3.             TERM OF LEASE

3.1           Term. The Term of this Lease is ten (10) years (or until such Term shall sooner cease or expire) commencing on the Term Commencement Date and ending on the day immediately prior to the tenth (10th) anniversary thereof, except that if the Term Commencement Date is other than the first day of a calendar month, the Term of this Lease shall end on the last day of the calendar month in which said tenth (10th) anniversary occurs.

4.             WORK BY LANDLORD; TENANT’S ACCESS

4.1           Completion Date - Delays. Subject to delay by causes beyond the reasonable control of Landlord or caused by the action or inaction of Tenant, Landlord shall use reasonable diligence in order to have the Demised Premises ready for occupancy by Tenant as soon as practicable. The failure to have the Demised Premises so ready by a particular date shall in no way affect the validity of this Lease or the obligations of Tenant hereunder, provided however that Tenant may terminate this Lease by notice given to Landlord at any time after May 31, 2001 if the Demised Premises are not ready for Tenant’s occupancy within fifteen (15) days following receipt of such notice.

4.2           When Premises Deemed Ready. The Demised Premises shall be conclusively deemed ready for Tenant’s occupancy after Landlord gives notice to Tenant, together with a certificate from Landlord’s Architect, that the installations to be done by Landlord in the Demised Premises (as hereinafter set forth in this Article) have been substantially completed by Landlord insofar as is practicable in view of delays or defaults, if any, of Tenant. Such work shall not be deemed incomplete if only minor or insubstantial details of construction or

3

mechanical adjustments remain to be done, or if a delay is caused in whole or in part by Tenant through the delay of Tenant in submitting any plans and/or specifications, supplying information, approving plans, specifications or estimates, giving authorization or otherwise. Landlord’s Architect’s certificate of substantial completion, as hereinabove stated, given in good faith, or of any other facts pertinent to this Article, shall be deemed conclusive of the statements therein contained and binding upon Tenant.   Following the completion of the work to be performed by Landlord pursuant to this Article, Landlord shall obtain from the Boston Inspectional Services Department a certificate authorizing the use and occupancy of the Demised Premises pursuant to the applicable provisions of the Massachusetts State Building Code. Landlord will save Tenant harmless, and will exonerate and indemnify Tenant from and against, any claims, liabilities, penalties, damages, losses, costs and expenses (including without limitation reasonable attorneys’ fees) resulting from Landlord’s failure to obtain such certificate.

4.3           Landlord’s Work. Landlord shall, at Landlord’s expense, perform the work described in Exhibit B attached hereto and made a part hereof in order to make certain improvements to the so-called shell and core of the Building (hereinafter referred to as the “Base Building Work”). In addition, Landlord shall perform such further work as may be necessary to lay out the Demised Premises for Tenant’s occupancy (hereinafter referred to as the “Premises Work”). Tenant shall furnish final architectural, electrical and mechanical construction drawings and specifications describing the Premises Work (hereinafter referred to as the “Plans”). The Plans shall be subject to approval by Landlord and Landlord’s Architect (which approval shall not be unreasonably withheld or delayed in the case of any proposed Premises Work of an interior, non-structural nature) and shall be prepared so as to comply with their requirements in order to avoid conflict with the design and function of the Building. It shall be Tenant’s responsibility to assure that the Plans have been delivered to Landlord and approved as aforesaid on or before the Final Plans Date. Tenant has assured itself by direct communication with architects and engineers that the final, approved Plans can be delivered to Landlord on or before the Final Plans Date, provided that Tenant promptly furnishes complete information concerning its requirements to said architects and engineers as and when requested by them; and Tenant covenants and agrees to cause said final, approved Plans to be delivered to Landlord on or before said Final Plans Date and to devote such time as may be necessary in consultation with said architects and engineers to enable them to complete and submit all Plans within the required time limit. Following the presentation to Landlord of invoices and receipts evidencing to Landlord’s reasonable satisfaction the architectural and engineering costs incurred by Tenant with respect to the Plans, Landlord shall pay to Tenant an amount equal to such costs (hereafter referred to as the “Design Allowance”). Landlord shall solicit bids from the contractors identified on Exhibit B-1 attached hereto and made a part hereof for the performance of the Premises Work subject to such terms and conditions as Landlord may customarily prescribe for projects of such type. Landlord shall provide copies of such bids to Tenant and Tenant shall, within seven (7) days thereafter, select a contractor from among the bidders to perform the Premises Work.

4.4           Conclusiveness of Landlord’s Performance. Tenant shall be conclusively deemed to have agreed that Landlord has performed all of its obligations under this Article 4 unless not later than the end of the ninth calendar month next beginning after Landlord’s notice of substantial completion under Section 4.2 Tenant shall give Landlord written notice specifying the respects in which Landlord has not performed such obligations. Landlord shall promptly correct any defective or incomplete items of work specified in any such notice. Landlord shall in

4

all events be responsible throughout the Term of this Lease for performance of the repairs described in Section 7.4, and shall further use reasonable efforts to enforce on Tenant’s behalf any warranties received by Landlord in connection with the work described in the Plans.

4.5           Entry by Tenant; Interference With Construction. In the event that Tenant is permitted by Landlord to enter the Demised Premises prior to the Term Commencement Date to undertake such work as is to be performed by Tenant pursuant to this Lease in order to prepare the Demised Premises for Tenant’s occupancy, such entry shall be deemed to be pursuant to a license from Landlord to Tenant and shall be at the risk of Tenant. In no event shall Tenant interfere with any construction work being performed by or on behalf of Landlord in or around the Building; without limiting the generality of the foregoing, Tenant shall comply with all instructions issued by Landlord’s contractors relative to the moving of Tenant’s equipment and other property into the Demised Premises and shall pay any fees or costs imposed in connection therewith.

4.6           Tenant’s Cost. Tenant shall bear all costs incurred by Landlord in order to perform the Premises Work to the extent that such costs exceed Landlord’s Contribution (as such term is hereinafter defined). Payment of such excess costs shall be made prorata as the Premises Work progresses, and within ten (10) days next following periodic billings by Landlord to Tenant. For purposes hereof, “Landlord’s Contribution” shall mean the sum of $938,775 less the Design Allowance.

4.7           Change Orders. Tenant may from time to time propose revisions to the Plans. Landlord shall not unreasonably withhold its consent to any such revisions of a non-structural nature which will not tend to delay completion of Landlord’s work hereunder and do not affect the common areas or facilities of the Property. To the extent that the Plans are revised hereunder so as to result in any increase or decrease in the cost of such work, the amount of such increase shall be added to and the amount of such decrease shall subtracted from the amount which Tenant is obligated to pay pursuant to Section 4.6.

5.             USE OF PREMISES

5.1           Permitted Use. Tenant may during the Term of this Lease occupy and use the Demised Premises for the permitted Use set forth in Article 1 and for no other purpose.

5.2           Prohibited Uses. Tenant shall not use, or suffer or permit the use of, or suffer or permit anything to be done in or anything to be brought into or kept in, the Demised Premises or any part thereof (i) which would violate any of the covenants, agreements, terms, provisions and conditions of this Lease, (ii) for any unlawful purposes or in any unlawful manner, or (iii) which, in the reasonable judgment of Landlord shall in any way (a) impair or tend to impair the appearance or reputation of the Building, (b) impair or interfere with or tend to impair or interfere with any of the Building services or the proper and economic heating, cleaning, air conditioning or other servicing of the Building or with the use of any of the other areas of the Building, or (c) occasion discomfort, inconvenience or annoyance to any of the other tenants or occupants of the Building, whether through the transmission of noise or odors or otherwise.

Tenant, at Tenant’s expense, shall at all times comply with the terms and conditions of each such license or permit.

6.             RENT

6.1           Yearly Fixed Rent. Tenant shall pay to Landlord, without any set-off or deduction, at Landlord’s office, or to such other person or at such other place as Landlord may designate by notice to Tenant, the Yearly Fixed Rent set forth in Article 1, provided however that, if Tenant duly exercises its option pursuant to Section 3.3 to extend the Term hereof, the Yearly Fixed Rent shall be increased effective as of the commencement of such extension period to reflect the fair market rental value of the Demised Premises for the balance of the Term of this Lease, taking into account Tenant’s obligations to pay Additional Rent and all other provisions of this Lease. If Tenant so requests in writing, Landlord shall, within ten (10) days following receipt of such request (but no sooner than fifteen (15) months prior to the originally-scheduled Termination Date) notify Tenant of Landlord’s opinion as to said fair market rental value. If no such request has been received by Landlord, Landlord shall render such opinion following Tenant’s exercise of its option to extend the Term of the Lease as aforesaid, and if Landlord and Tenant have not in any event mutually agreed upon the same as of the thirtieth (30th) day following Landlord’s receipt of Tenant’s notice of such exercise, then in such event said fair market rental value shall be determined by appraisers, one to be chosen by Landlord, one to be chosen by Tenant, and a third to be selected by the two first chosen. All appraisers chosen or selected hereunder shall be independent of the parties, shall have received the M.A.I. (Member, Appraisal Institute) designation from the American Institute of Real Estate Appraisers and shall have had at least ten (10) years of experience in appraising office space in the downtown or Fort Point Channel sections of the City of Boston. The unanimous written decision of the first two chosen, without selection and participation of a third appraiser, or otherwise the written decision of a majority of three appraisers chosen and selected as aforesaid, shall be conclusive and binding upon Landlord and Tenant. Landlord and Tenant shall each notify the other of its chosen appraiser within ten (10) days following expiration of the aforesaid thirty (30) day period and, unless such two appraisers shall have reached a unanimous decision within thirty (30) days

6

after having been chosen, they shall within a further ten (10) days elect a third appraiser and notify Landlord and Tenant thereof. Each party shall bear the expense of the appraiser chosen by such party pursuant to this Section, and the parties shall equally share the expense of the third appraiser (if any). If the Yearly Fixed Rent for such extension period shall not have been “ determined prior to the commencement thereof, Tenant shall continue to pay Yearly Fixed Rent at the rate most recently in effect, subject to retroactive adjustment once the Yearly Fixed Rent for such period has in fact been determined. In no event shall the foregoing provisions be construed so as to result in any reduction in the Rent payable by Tenant or in any increase in Yearly Fixed Rent so as to exceed the value set forth in the opinion rendered by Landlord as aforesaid. Yearly Fixed Rent shall be paid in equal monthly installments in advance on or before the first Business Day of each calendar month during the Term of this Lease and shall be apportioned for any fraction of a month in which Yearly Fixed Rent first becomes payable or in which the last day of the Term of this Lease may fall.

6.2           Taxes. Tenant shall pay to Landlord as Additional Rent a proportionate share (as defined in Section 6.4) of all real estate taxes (including without limitation all betterment assessments, all fire service availability fees and similar charges for customary governmental services, all other charges in lieu of such taxes and any tax on any fixture installed in the Building, even if taxed as personal property) imposed against the Building and the Land, in excess of $222,732.50, pro-rated with respect to any portion of a fiscal year in which the Term of this Lease begins or ends. Such payments shall be due and payable in installments corresponding to those in which such taxes are payable by Landlord, and within fifteen (15) days after Tenant shall have received a copy of the relevant tax bills. If Landlord shall receive any refund of real estate taxes of which Tenant has paid a portion pursuant to this Section, then, out of any balance remaining after deducting Landlord’s expenses incurred in obtaining such refund, Landlord shall pay to Tenant the same proportionate share of said balance, prorated as set forth above. Tenant shall, if as and when demanded by Landlord and with each monthly installment of Yearly Fixed Rent, make tax fund payments to Landlord. “Tax fund payments” refer to such payments as Landlord shall reasonably determine to be sufficient to provide in the aggregate a fund adequate to pay, when they become due and payable, all payments required from Tenant under this Section. In the event that said tax fund payments are so demanded, and if the aggregate of said tax fund payments is not adequate to pay Tenant’s share of such taxes, Tenant shall pay to Landlord the amount by which such aggregate is less than the amount of said share such payment to be due and payable at the time set forth above. Any surplus tax fund payments shall be accounted for to Tenant after payment by Landlord of the taxes on account of which they were made, and shall be credited by Landlord against future tax fund payments or refunded to Tenant at Tenant’s option.

6.3           Operating Expenses. Tenant shall pay to Landlord as Additional Rent a proportionate share (as defined in Section 6.4) of all annual costs and expenses incurred by Landlord in the operation and maintenance of the Building and the Land in excess of $445,465, including, without limiting the generality of the foregoing, all such costs and expenses in connection with (1) insurance, sprinkler service, license fees, security, trash and rubbish removal, janitorial service, landscaping, and snow removal, (2) wages, salaries, management fees (not exceeding 5% of rents and other Building revenue), employee benefits, payroll taxes, administrative and auditing expenses, and equipment and materials for the operation, management and maintenance of the Property, (3) any capital expenditure (amortized, with

7

interest, on such reasonable basis as Landlord shall determine) made by Landlord for the purpose of achieving a reasonably-corresponding reduction of other operating expenses or complying with any governmental requirement imposed after the date of this Lease, (4) the furnishing of heat, air conditioning, water and other utilities, (5) the operation and servicing of any computer system installed to regulate Building equipment, (6) the furnishing of the repairs and services referred to in Section 7.4 and (7) unless such costs and expenses for a particular year include management fees, a supervisory and overhead fee which shall be in an amount equal to ten percent (10%) of all other such costs and expenses (the foregoing being hereinafter referred to as “operating expenses”). If, during any portion of a fiscal year for which operating expenses are being computed pursuant to this Section, less than the entire rentable area of the Building is occupied or Landlord is not supplying all occupants with the same services being supplied hereunder, such costs and expenses shall be reasonably extrapolated in order to take into account the costs and expenses which would have been incurred had the entire rentable area of the Building been occupied and had such services been supplied to all occupants. As soon as Tenant’s share of operating expenses with respect to any fiscal year established from time to time by Landlord can be determined, the same will be certified by Landlord to Tenant and will become payable to Landlord within thirty (30) days following such certification, subject to proration with respect to any portion of a fiscal year in which the Term of this Lease begins or ends or in the event that Landlord designates a different fiscal year. Tenant shall, if as and when demanded by Landlord and with each monthly installment of Yearly Fixed Rent, make operating fund payments to Landlord. “Operating fund payments” refer to such payments as Landlord shall reasonably determine to be sufficient to provide in the aggregate a fund adequate to pay, when they become due and payable, all payments required from Tenant under this Section. In the event that operating fund payments are so demanded, and if the aggregate of said operating fund payments is not adequate to pay Tenant’s share of operating expenses, Tenant shall pay to Landlord the amount by which such aggregate is less than the amount of said share, such payment to be due and payable at the time set forth above. Any surplus operating fund payments shall be accounted for to Tenant after such surplus has been determined, and shall be credited by Landlord against future operating fund payments or refunded to Tenant at Tenant’s option.

6.4           Tenant’s Proportionate Share. Tenant’s proportionate share of taxes and operating expenses pursuant to Sections 6.2 and 6.3 shall be computed according to the ratio (initially 42.14%, but subject to adjustment as of the last day of the relevant fiscal year in the event of any reconfiguration of the Demised Premises or structural expansion of the Building) between the Rentable Area of the Demised Premises (as defined in Article 1) and the total rentable area of all space in the Building. Computations of rentable area other than in the Demised Premises shall be made by Landlord’s Architect, whose good faith determination shall be conclusive and binding on Tenant.

6.5           Payment to Mortgagee. Landlord reserves the right to provide in any Mortgage given by it of the Property that some or all rents, issues, and profits and all other amounts of every kind payable to the Landlord under this Lease shall be paid directly to the Mortgagee for Landlord’s account and Tenant covenants and agrees that it will, after receipt by it of notice from Landlord designating such Mortgagee to whom payments are to be made by Tenant, pay such amounts thereafter becoming due directly to such Mortgagee until excused therefrom by notice from such Mortgagee.

Landlord shall not be liable in any way to Tenant for any failure or defect in the supply or character of electrical energy furnished to the Demised Premises by reason of any requirement, act or omission of the public utility serving the Building with electricity unless due to the act or omission of Landlord.

Tenant agrees that it will not make any alteration or material addition to the electrical equipment and/or appliances in the Demised Premises without the prior written consent of Landlord in each instance first obtained, which consent will not be unreasonably withheld, and will promptly advise Landlord of any alteration or addition to such electrical equipment and/or appliances.

In the latter event, Tenant shall pay the cost of the meter and the cost of installing any equipment required in connection therewith, and shall keep said meter and installation equipment in good working order and repair, and shall pay for water consumed, as shown on said meter, together with the sewer charge based on said meter charges, as and when bills are rendered.

Tenant agrees to lower and close the blinds or drapes when

(b)           Landlord’s only obligation under this Lease with respect to the air conditioning of the Demised Premises is to maintain the Building equipment servicing the Demised Premises and to furnish chilled water therefor. The distribution of air conditioning within the Demised Premises utilizes, as part of said equipment, handlers which are operated electrically at Tenant’s expense pursuant to Section 7.1.

(c)           Landlord will endeavor, upon reasonable advance written notice from Tenant of its requirements, to furnish additional heat or air conditioning service to the Demised Premises on days and at times other than as provided in this Article.

Landlord shall have no responsibility or liability for any such interruption, curtailment, stoppage, or suspension of services or systems, except that Landlord shall exercise reasonable diligence to eliminate the cause of same.

8.             CHANGES OR ALTERATIONS BY LANDLORD

Landlord reserves the right, exercisable by itself or its nominee, at any time and from time to time without the same constituting an actual or constructive eviction and without incurring any liability to Tenant therefor or otherwise affecting Tenant’s obligations under this Lease, to make such changes, alterations, additions, improvements, repairs or replacements in or

10

to the Building (including the Demised Premises) and the fixtures and equipment thereof, as well as in or to the street entrances, halls, passages, elevators, and stairways thereof, as it may deem necessary or desirable, and to change the arrangement and/or location of entrances or passageways, doors and doorways, and corridors, elevators, stairs, toilets, or other public parts of the Building, provided, however, that there be no unreasonable obstruction of the right of access to, or unreasonable interference with the use and enjoyment of, the Demised Premises by Tenant, except that Landlord shall not be obligated to employ labor at so-called “over-time” or other premium pay rates. Nothing contained in this Article shall be deemed to relieve Tenant of any duty, obligation or liability of Tenant with respect to making or causing to be made any repair, replacement or improvement or complying with any law, order or requirement of any governmental or other authority. Landlord reserves the right to from time to time change the address of the Building.

9.             FIXTURES, EQUIPMENT AND IMPROVEMENTS - REMOVAL BY TENANT

Tenant shall make, as and when needed as a result of misuse by, or neglect or improper conduct (including without limitation the placement of any equipment exceeding the floor load or causing vibrations) of Tenant or Tenant’s servants, employees, agents, invitees or licensees or otherwise, all repairs in and about the Demised Premises necessary to preserve them in such repair, order and condition.

Such insurance shall be effected with insurers authorized to do business in Massachusetts under valid and enforceable policies, and such policies shall name Landlord and Tenant and any additional parties designated by Landlord pursuant to Section 13.1 as the insureds, as their respective interests appear. Such insurance shall provide that it shall not be cancelled without at least ten (10) days’ prior written notice to each insured named therein. Prior to entry by Tenant and/or its contractors into the Demised Premises in accordance with Article 4 of this Lease, and thereafter not less than fifteen (15) days prior to the expiration date of each expiring policy, original copies of the policies provided for in Section 13.1 issued by the respective insurers, or certificates of such policies setting forth in full the provisions thereof and issued by such insurers together with evidence satisfactory to Landlord of the payment of all premiums for such policies, shall be delivered by Tenant to Landlord and certificates as aforesaid of such policies shall upon request of Landlord be delivered by Tenant to any additional parties designated by Landlord pursuant to Section 13.1 as the insureds.

13.3         General. Tenant will save Landlord harmless, and will exonerate and indemnify Landlord, from and against any and all claims, liabilities or penalties asserted by or on behalf of any person, firm, corporation or public authority:

(a)           On account of or based upon any injury to person, or loss of or damage to property sustained or occurring on the Demised Premises on account of or based upon the act, omission, fault, negligence or misconduct of any person whomsoever (other than Landlord or its agents, contractors or employees);

(b)           On account of or based upon any injury to person or loss of or damage to property, sustained or occurring elsewhere (other than on the Demised Premises) in or about the Building (and, in particular, without limiting the generality of the foregoing on or about the elevators, stairways, public corridors, sidewalks or other appurtenances and facilities used in connection with the Building or Demised Premises) arising out of the use or occupancy of the Building or Demised Premises by Tenant, or any person claiming by, through or under Tenant;

13

(c)           On account of or based upon (including moneys due on account of) any work or thing whatsoever done (other than by Landlord or its contractors, or agents or employees of either) in the Demised Premises; and

and, in respect of any of the foregoing items (a)-(d), from and against all costs, expenses (including without limitation reasonable attorneys’ fees), and liabilities incurred in or in connection with any such claim, or any action or proceeding brought thereon; and in case any action or proceeding be brought against Landlord by reason of any such claim, Tenant upon notice from Landlord shall at Tenant’s expense resist or defend such action or proceeding and employ counsel therefor reasonably satisfactory to Landlord, it being agreed that such counsel as may act for insurance underwriters of Tenant engaged in such defense shall be deemed satisfactory.

Landlord will save Tenant harmless, and will exonerate and indemnify Tenant from and against, any and all claims, liabilities, penalties, damages, losses, costs and expenses (including reasonable attorneys’ fees) asserted against or incurred by Tenant on account of or based upon the act, omission, fault, negligence or misconduct of Landlord or its agents, contractors or employees; and, in case any action or proceeding be brought against Tenant by reason of any of the foregoing, Landlord upon notice from Tenant shall at Landlord’s expense resist or defend such action or proceeding and employ counsel therefor reasonably satisfactory to Tenant, it being agreed that such counsel as may act for insurance underwriters of Landlord engaged in such defense shall be deemed satisfactory.

Each party, upon receiving notice of any claim against which the other party has agreed to provide indemnification pursuant to this Section or elsewhere in this Lease, shall promptly so notify the other party.

13.4         Property of Tenant. In addition to and not in limitation of the foregoing, and subject only to the provisions of applicable law, Tenant covenants and agrees that all merchandise, furniture, fixtures and property of every kind, nature and description which may be in or upon the Demised Premises or the Building or the Land during the Term of this Lease shall be at the sole risk and hazard of Tenant, and that if the whole or any part thereof shall be damaged, destroyed, stolen or removed from any cause or reason whatsoever no part of said damage or loss shall be charged to, or borne by Landlord.

13.5         Bursting of Pipes, etc. Landlord shall not be liable for any injury or damage to persons or property resulting from fire, explosion, falling plaster, steam, gas, electricity, electrical disturbance, water, rain or snow or leaks from any part of the Building or from the pipes, appliances or plumbing works or from the roof, street or sub-surface or from any other place or caused by any other cause of whatever nature, unless caused by or due to the negligence of Landlord, its agents, servants or employees, and then only after (i) notice to Landlord of the condition claimed to constitute negligence and (ii) the expiration of a reasonable time after such notice has been received by Landlord without such condition having been cured or corrected; nor shall Landlord or its agents be liable for any such damage caused by other tenants or persons in

14

the Building or caused by operations in construction of any private, public or quasi-public work; nor shall Landlord be liable (subject only to its repair obligations hereunder) for any latent defect in the Demised Premises or in the Building.

14.           ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

Tenant covenants and agrees that neither this Lease nor the term and estate hereby granted nor any interest herein or therein, will be assigned, mortgaged, pledged, encumbered or otherwise transferred (whether voluntarily or by operation of law), and that neither the Demised Premises, nor any part thereof, will be encumbered in any manner by reason of any act or omission on the part of Tenant, or used or occupied, or permitted to be used or occupied, or utilized for any reason whatsoever, by anyone other than Tenant, or for any use or purpose other than as stated in Article 1, or be sublet, or offered or advertised for subletting, without the prior written consent of Landlord in every case. Such consent shall not, in the case of a proposed subletting, be unreasonably withheld or delayed.

In connection with any request by Tenant for such consent, Tenant shall submit to Landlord, in writing, a statement containing all of the terms and provisions upon which the proposed transaction is to occur. If the rent received by Tenant on account of a proposed assignment or sublease exceeds the Yearly Fixed Rent and Additional Rent, allocated to the space subject to the assignment or sublease in the proportion of the area of such space to the area of the entire Demised Premises, plus actual out-of-pocket expenses incurred by Tenant in connection therewith, including brokerage commissions and the cost of preparing such space for occupancy, Tenant shall pay to Landlord fifty (50) percent of such excess, as received by Tenant.  Notwithstanding the foregoing provisions of this paragraph, (1) in the event Tenant proposes to assign this Lease or enter into a sublease such that all or substantially all of the Demised Premises will have been sublet, Landlord, at Landlord’s option, may give to Tenant, within thirty (30) days after the submission by Tenant to Landlord of such proposal, a notice terminating this Lease on the date (referred to as the “Earlier Termination Date”) immediately prior to the effective date of the proposed assignment or the proposed commencement date of the term of the proposed subletting, as set forth in such proposal, and, in the event such notice is given, this Lease and the Term shall come to an end and expire on the Earlier Termination Date with the same effect as if it were the date originally fixed in this Lease for the end of the Term of this Lease, and the Rent shall be apportioned as of said Earlier Termination Date and any prepaid portion of Rent for any period after such date shall be refunded by Landlord to Tenant, or (2) in the event Tenant proposes to sublet any portion of the Demised Premises such that more than 40% of the floor area of the Demised Premises will have been sublet, Landlord, at Landlord’s option, may give to Tenant, within thirty (30) days after the submission by Tenant to Landlord of the statement required to be submitted in connection with such proposed subletting, a notice electing to eliminate such portion of the Demised Premises (said portion is referred to as the “Eliminated Space”) from the Demised Premises during the period (referred to as the “Elimination Period”) commencing on the date (referred to as the “Elimination Date”) immediately prior to the proposed commencement date of the term of the proposed subletting, as set forth in such statement, and ending on the proposed expiration date of the term of the proposed subletting, as set forth in such statement, and in the event such notice is given (i) the Eliminated Space shall be eliminated from the Demised Premises during the Elimination Period; (ii) Tenant shall surrender the Eliminated Space to Landlord on or prior to the Elimination Date

15

in the same manner as if said Date were the date originally fixed in this Lease for the end of the Term of this Lease; (iii) if the Eliminated Space shall constitute less than an entire floor, Landlord, at Landlord’s expense, shall have the right to make any alterations and installations in the Demised Premises required, in Landlord’s judgment, reasonably exercised, to make the Eliminated Space a self-contained rental unit with access through corridors to the elevators and core toilets serving the Eliminated Space, and if the Demised Premises shall contain any core toilets or any corridors (including any corridors proposed to be constructed by Landlord pursuant to this subdivision (iii) providing access from the Eliminated Space to the core area), Landlord and any tenant or other occupant of the Eliminated Space shall have the right to use such toilets and corridors in common with Tenant and any other permitted occupants of the Demised Premises, and the right to install signs and directional indicators in or about such corridors indicating the name and location of such tenant or other occupant; (iv) during the Elimination Period, the Yearly Fixed Rent shall be reduced in the proportion which the area of the Eliminated Space bears to the total area of the Demised Premises immediately prior to the Elimination Date (including an equitable portion of the area of any corridors referred to in subdivision (iii) of this sentence as part of the area of the Eliminated Space for the purpose of computing such reduction), and any prepaid Rent for any period after the Elimination Date allocable to the Eliminated Space shall be refunded by Landlord to Tenant; (v) there shall be an equitable apportionment of any Additional Rent payable pursuant to Article 6 for the relevant fiscal and calendar years in which said Elimination Date shall occur; and (vi) if the Elimination Period shall end prior to the date originally fixed in this Lease for the end of the Term of this Lease, the Eliminated Space, in its then existing condition, shall be deemed restored to and once again a part of the Demised Premises subject to the provisions of this Lease as if said elimination had not occurred during the period (referred to as the “Restoration Period”) commencing on the date next following the expiration of the Elimination Period and ending on the date originally fixed in this Lease for the end of the Term of this Lease, except in the event that Landlord is unable to give Tenant possession of the Eliminated Space at the expiration of the Elimination Period by reason of the holding over or retention of possession of any tenant or other occupant, in which event (x) the Restoration Period shall not commence, and the Eliminated Space shall not be deemed restored to or a part of the Demised Premises, until the date upon which Landlord shall give Tenant possession of such Space free of occupancies, (y) neither the date fixed in this Lease for the end of the Term of the Lease, nor the validity of this Lease shall be affected, and (z) Tenant waives any right to recover any damages which may result from the failure of Landlord (despite the exercise of diligent efforts) to deliver possession of the Eliminated Space at the end of the Elimination Period. At the request of Landlord, Tenant shall execute and deliver an instrument or instruments, in form satisfactory to Landlord, setting forth any modifications to this Lease contemplated in or resulting from the operation of the foregoing provisions of this paragraph; however, neither Landlord’s failure to request any such instrument nor Tenant’s failure to execute or deliver any such instrument shall vitiate the effect of the foregoing provisions of this paragraph.

The failure by Landlord to exercise its option under this Article with respect to any assignment or subletting shall not be deemed a waiver of such option with respect to any extension of such sublease or any subsequent assignment or subletting. Tenant shall reimburse Landlord promptly, as Additional Rent, for reasonable legal and other expense incurred by

16

Landlord in connection with any request by Tenant for any consent required under the provisions of this Article.

Notwithstanding the foregoing, Tenant may, following notice to Landlord but without the requirement of obtaining Landlord’s consent or affording Landlord an opportunity to terminate this Lease or eliminate any portion of the Demised Premises therefrom or share any excess rent, all as hereinabove set forth, and so long as Tenant is not in default hereunder beyond the applicable grace period, assign this Lease or sublease all or any portion of the Demised Premises to any entity which is controlled by, or which controls, or which is under common control with, Tenant, or assign this Lease to any entity with which Tenant may merge or consolidate or to which Tenant may sell all or substantially all of its assets as a going concern or to which a controlling interest in the corporation or other entity constituting Tenant may be transferred (such entity with which Tenant may merge or consolidate or to which Tenant may sell all or substantially all of its assets or to which a controlling interest in the corporation or other entity constituting Tenant may be transferred as aforesaid being hereinafter referred to as a “Successor”), provided however that, forthwith upon any assignment allowed pursuant to this paragraph, Tenant shall deliver to Landlord an agreement in form and substance reasonably satisfactory to Landlord which contains an appropriate covenant of assumption by such assignee, and provided further that in the case of any such assignment to a Successor, such Successor shall have financial resources and a general business reputation comparable to those of Tenant as of the time of such assignment.

The listing of any name other than that of Tenant, whether on the doors of the Demised Premises or on the Building directory, or otherwise, shall not operate to vest any right or interest in this Lease or in the Demised Premises or be deemed to be the written consent of Landlord mentioned in this Article, it being expressly understood that any such listing is a privilege extended by Landlord revocable at will by written notice to Tenant.

If this Lease be assigned, or if the Demised Premises or any part thereof be sublet or occupied by anybody other than Tenant, Landlord may at any time and from time to time, collect rent and other charges from the assignee, subtenant or occupant, and apply the net amount collected to the Rent and other charges herein reserved, but no such collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, subtenant or occupant as a tenant, or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained. The consent by Landlord to an assignment or subletting or occupancy shall not in any way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting or occupancy.

15.           MISCELLANEOUS COVENANTS

15.1         Rules and Regulations. Tenant and Tenant’s servants, employees, agents, visitors and licensees will faithfully observe such Rules and Regulations as are attached hereto as Exhibit D and made a part hereof or as Landlord hereafter at any time or from time to time may make and may communicate in writing to Tenant and which in the reasonable judgment of Landlord shall be necessary for the reputation, safety, care or appearance of the Property, or the preservation of good order therein, or the operation or maintenance of the Property, or the equipment thereof, or the comfort of tenants or others in the Building, provided however that in

17

the case of any conflict between the provisions of this Lease and any such Rules and Regulations, the provisions of this Lease shall control. Such Rules and Regulations shall be applied in a non-discriminatory manner so as to be generally applicable to other tenants of the Building whose permitted business activities are comparable to those of Tenant hereunder, provided however that nothing contained in this Lease shall be construed to impose upon Landlord any duty or obligation to enforce such Rules and Regulations or the terms, covenants or conditions in any other lease as against any other tenant and Landlord shall not be liable to Tenant for violation of the same by any other tenant, its servants, employees, agents, visitors, invitees or licensees.

15.2         Access to Premises - Shoring. Tenant shall: (i) permit Landlord to erect, use and maintain pipes, ducts and conduits in and through the Demised Premises, provided the same do not materially reduce the floor area or materially adversely affect the appearance thereof; (ii) permit Landlord and any Mortgagee to have free and unrestricted access to and to enter upon the Demised Premises at all reasonable hours for the purposes of inspection or of making repairs, replacements or improvements in or to the Demised Premises or the Building or equipment (including, without limitation, sanitary, electrical, heating, air conditioning or other systems) or of complying with all laws, orders and requirements of governmental or other authority or of exercising any right reserved to Landlord by this Lease (including the right during the progress of any such repairs, replacements or improvements or while performing work and furnishing materials in connection with compliance with any such laws, orders or requirements to take upon or through, or to keep and store within, the Demised Premises all necessary materials, tools and equipment); and (iii) permit Landlord, at reasonable times, to show the Demised Premises during ordinary business hours to any Mortgagee, prospective purchaser of any interest of Landlord in the Property, prospective Mortgagee, or prospective assignee of any Mortgage, and during the period of twelve months next preceding the Termination Date to any person contemplating the leasing of the Demised Premises or any part thereof. If during the last month of the Term, Tenant shall have removed all of Tenant’s property therefrom, Landlord may immediately enter and alter, renovate and redecorate the Demised Premises, without elimination or abatement of Rent, or incurring liability to Tenant for any compensation, and such acts shall have no effect upon this Lease. If Tenant shall not be personally present to open and permit any entry into the Demised Premises at any time when for any reason an entry therein shall be necessary or permissible, Landlord or Landlord’s agents must nevertheless be able to gain such entry by contacting a responsible representative of Tenant, whose name, address and telephone number shall be furnished by Tenant, or (at Landlord’s election) by using keys to the Demised Premises in Landlord’s possession. Locks serving the Demised Premises shall not be altered or replaced, nor shall new locks be added by Tenant without the prior written consent of Landlord in every case. Provided that Landlord shall incur no additional expense thereby, Landlord shall exercise its rights of access to the Demised Premises permitted under any of the terms and provisions of this Lease in such manner as to minimize to the extent practicable interference with Tenant’s use and occupation of the Demised Premises. If an excavation shall be made upon land adjacent to the Demised Premises or shall be authorized to be made, Tenant shall afford, to the person causing or authorized to cause such excavation, license to enter upon the Demised Premises for the purpose of doing such work as said person shall deem necessary to preserve the Building from injury or damage and to support the same by proper foundations without any claim for damage or indemnity against Landlord, or diminution or abatement of Rent.

18

15.3         Accidents to Sanitary and other Systems. Tenant shall give to Landlord prompt notice of any fire or accident in the Demised Premises or in the Building and of any damage to, or defective condition in, any part or appurtenance of the Building’s systems located in, or passing through, the Demised Premises.

15.4         Signs, Blinds and Drapes. Tenant shall not place any signs on the exterior of the Building or on or in any window, public corridor or door visible from the exterior of the Demised Premises without the prior written consent of Landlord in every case. Landlord shall include Tenant’s name in any standard Building directory maintained by Landlord. No blinds may be put on or in any window nor may any Building drapes or blinds be removed by Tenant. Tenant may hang its own drapes, provided that they shall not, without the prior written approval of Landlord, in any way interfere with any Building drapery or blinds or be visible from the exterior of the Building.

15.5         Estoppel Certificate. Tenant shall at any time and from time to time upon not less than ten (10) days’ prior notice by Landlord to Tenant, execute, acknowledge and deliver to Landlord a statement in writing certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications), and the dates to which Rent has been paid in advance, if any, and stating whether or not to the best knowledge of the signer of such certificate Landlord is in default in performance of any covenant, agreement, term, provision or condition contained in this Lease and, if so, specifying each such default of which the signer may have knowledge, it being intended that any such statement delivered pursuant hereto may be relied upon by any prospective purchaser of any interest of Landlord in the Property, any Mortgagee or prospective Mortgagee, any lessee or prospective lessee thereof, any prospective assignee of any Mortgage, or any other party designated by Landlord.

15.6         Prohibited Items. Tenant shall not bring or permit to be brought or kept in or on the Demised Premises or elsewhere in the Building any hazardous, inflammable, combustible or explosive fluid, material, chemical or substance (except such as are related to Tenant’s use of the Demised Premises, provided that the same are stored and handled in a proper fashion consistent with applicable legal standards).

15.7         Requirements of Law - Fines and Penalties. Tenant at its sole expense shall comply with all laws, rules, orders and regulations of Federal, State, County and Municipal authorities and with any direction of any public officer or officers, pursuant to law, which shall impose any duty upon Landlord or Tenant with respect to and arising out of Tenant’s use or occupancy of the Demised Premises, provided however that Landlord shall be responsible for compliance therewith to the extent necessary to allow the continued use of the Demised Premises for general office purposes. In particular, Tenant shall be responsible for compliance with requirements imposed by the Americans with Disabilities Act relative to the layout of the Demised Premises or any work performed by Tenant therein, including without limitation all such requirements applicable to removing barriers, furnishing auxiliary aids and insuring that, whenever alterations are made, the affected portions of the Demised Premises are readily accessible to and usable by individuals with disabilities. Landlord shall be responsible for compliance with requirements imposed by said Act relative to the common areas of the Property and the work to be performed by Landlord pursuant to Article 4. If Tenant receives notice of any

19

violation of law, ordinance, order or regulation applicable to the Demised Premises, it shall give prompt notice thereof to Landlord.

15.8         Tenant’s Acts - Effect on Insurance. Tenant shall not do or permit to be done any act or thing upon the Demised Premises or elsewhere in the Building which will invalidate or be in conflict with any insurance policies covering the Building and the fixtures and property therein and shall not do, or permit to be done, any act or thing upon the Demised Premises which shall subject Landlord to any liability or responsibility for injury to any person or persons or to property by reason of any business or operation being conducted on the Demised Premises or for any other reason. Tenant at its own expense shall comply with all rules, orders, regulations or requirements of the Board of Fire Underwriters or any other similar body having jurisdiction, and shall not (i) do, or permit anything to be done, in or upon the Demised Premises, or bring or keep anything therein, except as now or hereafter permitted by the Fire Department, Board of Underwriters, Fire Insurance Rating Organization, or other authority having jurisdiction, and then only in such quantity and manner of storage as will not increase the rate for any insurance applicable to the Building, or (ii) use the Demised Premises in a manner which shall increase such insurance rates on the Building or on property located therein, over that applicable when Tenant first took occupancy of the Demised Premises hereunder. If by reason of failure of Tenant to comply with the provisions hereof the insurance rate applicable to any policy of insurance shall at any time thereafter be higher than it otherwise would be, then Tenant shall reimburse Landlord for that part of any insurance premiums thereafter paid by Landlord, which shall have been charged because of such failure by Tenant.

15.9         Miscellaneous. Tenant shall not suffer or permit the Demised Premises or any fixtures, equipment or utilities therein or serving the same, to be overloaded, damaged or defaced, nor permit any hole to be drilled or made in any part thereof. For purposes hereof, the capacity of the floors in the Demised Premises is agreed to be 250 pounds dead load per square foot.

16.           DAMAGE BY FIRE, ETC.

Landlord shall keep in force casualty insurance with respect to the Building (including for purposes hereof all improvements of a permanent nature made thereto) in an amount no less than the full replacement cost thereof. Such insurance shall afford protection against fire and the other perils customarily covered by a so-called “all risk” policy.

In the event of loss of, or damage to, the Demised Premises or the Building by fire or other casualty, the rights and obligations of the parties hereto shall be as follows:

(a)           If the Demised Premises, or any part thereof, shall be damaged by fire or other casualty, Tenant shall give prompt notice thereof to Landlord, and Landlord, upon receiving such notice, shall proceed promptly and with due diligence, subject to unavoidable delays, to repair, or cause to be repaired, such damage. If the Demised Premises or any part thereof shall be rendered untenantable by reason of such damage, whether to the Demised Premises or to the Building, Yearly Fixed Rent shall proportionately abate for the period from the date of such damage to the date when such damage shall have been repaired.

20

(b)           If, as a result of fire or other casualty, the whole or a substantial portion of the Building or the Demised Premises is rendered untenantable, Landlord, within ninety (90) days from the date of such fire or casualty, may terminate this Lease by notice to Tenant, specifying a date not less than twenty (20) nor more than forty (40) days after the giving of such notice on which the Term of this Lease shall terminate. If Landlord does not so elect to terminate this Lease, then Landlord shall proceed with diligence to repair the damage to the Demised Premises and all facilities serving the same, if any, which shall have occurred, and the Yearly Fixed Rent shall meanwhile proportionately abate, all as provided in Paragraph (a) of this Section. However, if such damage is not repaired and the Demised Premises restored to substantially the same condition as they were prior to such damage within six (6) months from the date of such damage, Tenant within fifteen (15) days from the expiration of such six (6) month period or from the expiration of any extension thereof by reason of unavoidable delays as hereinafter provided, may terminate this Lease by notice to Landlord, specifying a date not more than sixty (60) days after the giving of such notice on which the Term of this Lease shall terminate. The period within which the required repairs may be accomplished shall be extended by the number of days, not to exceed ninety (90) days, lost as a result of unavoidable delays, which term shall be defined to include all delays referred to in Article 24.

(c)           If the Demised Premises shall be rendered untenantable by fire or other casualty during the last year of the Term of this Lease, either party may terminate this Lease effective as of the date of such fire or other casualty upon notice to the other given within thirty (30) days after such fire or other casualty.

(d)           Landlord shall not be required to repair or replace any of Tenant’s business machinery, equipment, cabinet work, furniture, personal property or other installations (all of which shall, however, be restored by Tenant as soon as practicable after Landlord shall have completed any repair or restoration required under the terms of this Article), and no damages, compensation or claim shall be payable by Landlord for inconvenience, loss of business or annoyance arising from any repair or restoration of any portion of the Demised Premises or of the Building. Any insurance proceeds received by Tenant in connection with such loss or damage shall be applied by Tenant to such repair or restoration to the extent reasonably necessary to accomplish the same.

(e)           The provisions of this Article shall be considered an express agreement governing any instance of damage or destruction of the Building or the Demised Premises by fire or other casualty, and any law now or hereafter in force providing for such a contingency in the absence of express agreement shall have no application.

(f)            In the event of any termination of this Lease pursuant to this Article, the Term of this Lease shall expire as of the effective termination date as fully and completely as if such date were the date herein originally scheduled as the Termination Date.

(g)           Landlord’s Architect’s certificate, given in good faith, shall be deemed conclusive of the statements therein contained and binding upon Tenant with respect to the performance and completion of any repair or restoration work undertaken by Landlord pursuant to this Article or Article 18.

21

17.           WAIVER OF SUBROGATION

In any case in which Tenant shall be obligated under any provision of this Lease to pay to Landlord any loss, cost, damage, liability, or expense suffered or incurred by Landlord, Landlord shall allow to Tenant as an offset against the amount thereof the net proceeds of any insurance collected by Landlord for or on account of such loss, cost, damage, liability or expense, provided that the allowance of such offset does not invalidate or prejudice the policy or policies under which such proceeds were payable.

In any case in which Landlord shall be obligated under any provision of this Lease to pay to Tenant any loss, cost, damage, liability or expense suffered or incurred by Tenant, Tenant shall allow to Landlord as an offset against the amount thereof (i) the net proceeds of any insurance collected by Tenant for or on account of such loss, cost, damage, liability, or expense, provided that the allowance of such offset does not invalidate the policy or policies under which such proceeds were payable and (ii) if such loss, cost, damage, liability or expense shall have been caused by a peril against which Tenant has agreed to procure insurance coverage under the terms of this Lease, the amount of such insurance coverage, whether or not actually procured by Tenant.

The parties hereto shall each endeavor to procure an appropriate clause in, or endorsement on, any fire or extended coverage insurance policy covering the Demised Premises and the Building and personal property, fixtures and equipment located thereon or therein, pursuant to which the insurance companies waive subrogation or consent to a waiver of right of recovery, and having obtained such clauses and/or endorsements of waiver of subrogation or consent to a waiver of right of recovery each party hereby agrees that it will not make any claim against or seek to recover from the other for any loss or damage to its property or the property of others resulting from fire or other perils covered by such fire and extended coverage insurance; provided, however, that the release, discharge, exoneration and covenant not to sue herein contained shall be limited by the terms and provisions of the waiver of subrogation clauses and/or endorsements or clauses and/or endorsements consenting to a waiver of right of recovery and shall be co-extensive therewith. If either party may obtain such clause or endorsement only upon payment of an additional premium, such party shall promptly so advise the other party and shall be under no obligation to obtain such clause or endorsement unless such other party pays the premium.

18.           CONDEMNATION - EMINENT DOMAIN

In the event that the whole or any part of the Building shall be taken or appropriated by eminent domain or shall be condemned for any public or quasi-public use, or (by virtue of any such taking, appropriation or condemnation) shall suffer any damage (direct, indirect or consequential) for which Landlord or Tenant shall be entitled to compensation then (and in any such event) this Lease and the Term hereof may be terminated at the election of Landlord by a notice in writing of its election so to terminate which shall be given by Landlord to Tenant within sixty (60) days following the date on which Landlord shall have received notice of such taking, appropriation or condemnation. In the event that a substantial part of the Demised Premises or of the means of access thereto within the perimeter of the Property shall be so taken, appropriated or condemned, then (and in any such event) this Lease and the Term hereof may be

22

terminated at the election of Tenant by a notice in writing of its election so to terminate which shall be given by Tenant to Landlord within sixty (60) days following the date on which Tenant shall have received notice of such taking, appropriation or condemnation.

Upon the giving of any such notice of termination (either by Landlord or Tenant) this Lease and the Term hereof shall terminate on or retroactively as of the date on which Tenant shall be required to vacate any part of the Demised Premises or shall be deprived of a substantial part of the means of access thereto, provided, however, that Landlord may in Landlord’s notice elect to terminate this Lease and the Term hereof retroactively as of the date on which such taking, appropriation or condemnation became legally effective. In the event of any such termination, this Lease and the Term hereof shall expire as of the effective termination date as fully and completely as if such date were the date herein originally scheduled as the Termination Date. If neither party (having the right so to do) elects to terminate this Lease, Landlord will, with reasonable diligence and at Landlord’s expense, restore the remainder of the Demised Premises, or the remainder of the means of access thereto, as nearly as practicably may be to the same condition as obtained prior to such taking, appropriation or condemnation in which event (i) a just proportion of the Yearly Fixed Rent, according to the nature and extent of the taking, appropriation or condemnation and the resulting permanent injury to the Demised Premises and the means of access thereto, shall be permanently abated, and (ii) a just proportion of the remainder of the Yearly Fixed Rent, according to the nature and extent of the taking, appropriation or condemnation and the resultant injury sustained by the Demised Premises and the means of access thereto, shall be abated until what remains of the Demised Premises and the means of access thereto shall have been restored as fully as may be for permanent use and occupation by Tenant hereunder. Except for any award specifically reimbursing Tenant for moving or relocation expenses, there are expressly reserved to Landlord all rights to compensation and damages created, accrued or accruing by reason of any such taking, appropriation or condemnation, in implementation and in confirmation of which Tenant does hereby acknowledge that Landlord shall be entitled to receive and retain all such compensation and damages, grants to Landlord all and whatever rights (if any) Tenant may have to such compensation and damages, and agrees to execute and deliver all and whatever further instruments of assignment as Landlord may from time to time request. In the event of any taking of the Demised Premises or any part thereof for temporary use, so long as the period thereof is not more than twelve (12) consecutive months and will not extend beyond the Termination Date, (i) this Lease shall be and remain unaffected thereby, and (ii) Tenant shall be entitled to receive for itself any award made for such use, provided, that if any taking is for a period extending beyond the Term of this Lease, such award shall be apportioned between Landlord and Tenant as of the Termination Date.

19.           DEFAULT

19.1         Conditions of Limitation - Re-entry - Termination. This Lease and the herein term and estate are upon the condition that if (a) Tenant shall neglect or fail to perform or observe any of the Tenant’s covenants herein, including (without limitation) the covenants with regard to the payment when due of Rent; or (b) Tenant shall be involved in financial difficulties as evidenced by an admission in writing by Tenant of Tenant’s inability to pay its debts generally as they become due, or by the making or offering to make a composition of its debts with its creditors; or (c) Tenant shall make an assignment or trust mortgage, or other conveyance or

23

transfer of like nature, of all or a substantial part of its property for the benefit of its creditors; or (d) the leasehold hereby created shall be taken on execution or by other process of law and shall not be revested in Tenant within sixty (60) days thereafter; or (e) a receiver, sequester, trustee or similar officer shall be appointed by a court of competent jurisdiction to take charge of all or a substantial part of Tenant’s property and such appointment shall not be vacated within sixty (60) days; or (f) any proceeding shall be instituted by or against Tenant pursuant to any of the provisions of any Act of Congress or State law relating to bankruptcy, reorganization, arrangements, compositions or other relief from creditors, and, in the case of any such proceeding instituted against it, if Tenant shall fail to have such proceeding dismissed within sixty (60) days or if Tenant is adjudged bankrupt or insolvent as a result of any such proceeding; or (g) any event shall occur or any contingency shall arise whereby this Lease, or the term and estate thereby created, would (by operation of law or otherwise) devolve upon or pass to any person, firm or corporation other than Tenant, except as expressly permitted under Article 14 hereof - then, and in any such event (except as hereinafter in Article 19.2 otherwise provided) Landlord may, in a manner consistent with applicable law, immediately or at any time thereafter declare this Lease terminated by notice to Tenant or, without further demand or notice, enter into and upon the Demised Premises (or any part thereof in the name of the whole), and in either such case (and without prejudice to any remedies which might otherwise be available for arrears of Rent or preceding breach of covenant and without prejudice to Tenant’s liability for damages as hereinafter stated), this Lease shall terminate.  The words “re-entry” and “re-enter” as used in this Lease are not restricted to their technical legal meaning. As used in items (b), (c), (e) and (f) of this Section, the term “Tenant” shall also be deemed to refer to any guarantor of Tenant’s obligations hereunder.

19.2         Damages - Assignment for Benefit of Creditors. For the more effectual securing by Landlord of the rent and other charges and payments reserved hereunder, it is agreed as a further condition of this Lease that if at any time Tenant shall make an assignment of its property for the benefit of its creditors under the terms of which the debts provable by its creditors shall be debts provable against the estate of insolvent debtors either under the laws of the Commonwealth of Massachusetts or under some law or laws other than the Bankruptcy Act as now or hereafter enacted, then and in any such case the same shall constitute a breach of this Lease, and the term and estate hereby created shall terminate ipso facto, without entry or other action by Landlord; and notwithstanding any other provisions of this Lease, Landlord shall forthwith upon such termination, without prejudice to any remedies which might otherwise be available for arrears of rent or other charges due hereunder or preceding breach of this Lease, be ipso facto entitled to recover as liquidated damages the sum of (a) the amount (reasonably discounted to present value) by which, at the time of such termination of this Lease, (i) the aggregate of the Rent projected over the period commencing with such termination and ending with the Termination Date stated in Article 1 exceeds (ii) the aggregate projected rental value of the Demised Premises for such period and (b) (in view of the uncertainty of prompt re-letting and the expense entailed in re-letting the Demised Premises) an amount equal to the Rent payable for and in respect of the calendar year next preceding the date of termination, as aforesaid. Upon such termination Landlord, may immediately or at any time thereafter, without demand or notice, enter into or upon the Demised Premises (or any part thereof in the name of the whole), and (without being taken or deemed to be guilty of any manner of trespass or conversion, and without being liable to indictment, prosecution or damages thereof) may, forcibly if necessary,

24

expel Tenant and those claiming under Tenant from the Demised Premises and remove therefrom the effects of Tenant and those claiming under Tenant.

19.3         Damages - Termination. Upon the termination of this Lease under the provisions of this Article, then except as hereinabove in Section 19.2 otherwise provided, Tenant shall pay to Landlord the Rent payable by Tenant to Landlord up to the time of such termination, shall continue to be liable for any preceding breach of covenant, and in addition, shall pay to Landlord as damages, at the election of Landlord

either:

(x)            the amount by which, at the time of the termination of this Lease (or at any time thereafter if Landlord shall have initially elected damages under Subparagraph (y), below), (i) the aggregate of the Rent projected over the period commencing with such time and ending on the originally-scheduled Termination Date as stated in Article 1 exceeds (ii) the aggregate projected rental value of the Demised Premises for such period, reasonably discounted in each case to present value,

or,

(y)           amounts equal to the Rent which would have been payable by Tenant had this Lease not been so terminated, payable upon the due dates therefor specified herein following such termination and until the originally-scheduled Termination Date as specified in Article 1, provided, however, if Landlord shall re-let the Demised Premises during such period, that Landlord shall credit Tenant with the net rents received by Landlord from such re-letting, such net rents to be determined by first deducting from the gross rents as and when received by Landlord from such re-letting the expenses incurred or paid by Landlord in terminating this Lease, as well as the expenses of re-letting, including altering and preparing the Demised Premises for new tenants, brokers’ commissions, and all other similar and dissimilar expenses properly chargeable against the Demised Premises and the rental therefrom, it being understood that any such re-letting may be for a period equal to or shorter or longer than the remaining term of this Lease; and provided, further, that (i) in no event shall Tenant be entitled to receive any excess of such net rents over the sums payable by Tenant to Landlord hereunder and (ii) in no event shall Tenant be entitled in any suit for the collection of damages pursuant to this Subparagraph (y) to a credit in respect of any net rents from a re-letting except to the extent that such net rents are actually received by Landlord prior to the commencement of such suit. If the Demised Premises or any part thereof should be re-let in combination with other space, then proper apportionment on a square foot area basis shall be made of the rent received from such re-letting and of the expenses of re-letting. Landlord shall endeavor in good faith to mitigate damages payable pursuant to the provisions of this subparagraph.

Suit or suits for the recovery of such damages, or any installments thereof, may be brought by Landlord from time to time at its election, and nothing contained herein shall be deemed to require Landlord to postpone suit until the date when the term of this Lease would have expired if it had not been terminated hereunder.

25

Nothing herein contained shall be construed as limiting or precluding the recovery by Landlord against Tenant of any sums or damages to which, in addition to the damages particularly provided above, Landlord may lawfully be entitled by reason of any default hereunder on the part of Tenant.

19.4         Fees and Expenses.  If Tenant shall default in the performance of any covenant on Tenant’s part to be performed as in this Lease contained, Landlord may immediately, or at any time thereafter, subject (except in case of emergency) to expiration of the applicable grace period, perform the same for the account of Tenant. If Landlord at any time is compelled to pay or elects to pay any sum of money, or do any act which will require the payment of any sum of money, by reason of the failure of Tenant to comply with any provision hereof, or if Landlord is compelled to or does incur any expense, including without limitation reasonable attorneys’ fees, in instituting, prosecuting and/or defending any action or proceeding arising by reason of any default of Tenant hereunder, Tenant shall on demand pay to Landlord by way of reimbursement the sum or sums so paid by Landlord with all interest, costs and damages. Without limiting the generality of the foregoing, in the event that any Rent is more than ten (10) days in arrears, Tenant shall pay, as Additional Rent, a delinquency charge equal to two and one-half percent (2-1/2%) of the arrearage for each calendar month (or fraction thereof) during which it remains unpaid.

19.5         Landlord’s Remedies Not Exclusive.  The specified remedies to which Landlord may resort hereunder are cumulative and are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be lawfully entitled, and Landlord may invoke any remedy (including without limitation the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for.

19.6         Grace Period.  Notwithstanding anything to the contrary in this Article contained, Landlord agrees not to take any action to terminate this Lease (a) for default by Tenant in the payment when due of Rent, if Tenant shall cure such default within ten (10) days after written notice thereof given by Landlord to Tenant, or (b) for default by Tenant in the performance of any other covenant, if Tenant shall cure such default within a period of thirty (30) days after written notice thereof given by Landlord to Tenant, or with respect to covenants other than to pay a sum of money within such additional period as may reasonably be required to cure such default if (because of governmental restrictions or any other cause beyond the reasonable control of Tenant) the default is of such a nature that it cannot be cured within such thirty (30)-day period, provided, however, (1) that there shall be no extension of time beyond such thirty (30)-day period for the curing of any such default unless, not more than twenty (20) days after the receipt of the notice of default, Tenant in writing (i) shall specify the cause on account of which the default cannot be cured during such period and shall advise Landlord of its intention duly to institute all steps necessary to cure the default and (ii) shall as soon as may be reasonable duly institute and thereafter diligently prosecute to completion all steps necessary to cure such default and, (2) that no notice of the opportunity to cure a default need be given, and no grace period whatsoever shall be allowed to Tenant, if the default is incurable or if the covenant or condition the breach of which gave rise to the default had, by reason of a breach on two (2) prior occasions during the preceding twelve (12) month period, been the subject of a notice hereunder to cure such default.

26

20.           END OF TERM - ABANDONED PROPERTY

Upon the expiration or other termination of the Term of this Lease, Tenant shall peaceably quit and surrender to Landlord the Demised Premises and all alterations and additions thereto which Tenant is not entitled or required to remove under the provisions of this Lease, broom clean in good order, repair and condition excepting only reasonable use and wear and damage by fire or other casualty for which, under other provisions of this Lease, Tenant has no responsibility of repair or restoration. Tenant’s obligation to observe or perform this covenant shall survive the expiration or other termination of the Term of this Lease. If the last day of the Term of this Lease or any renewal thereof falls on a day other than a Business Day, this Lease shall expire on the Business Day immediately preceding.

Any personal property in which Tenant has an interest which shall remain in the Building or on the Demised Premises after the expiration or termination of the Term of this Lease shall be conclusively deemed to have been abandoned, and may be disposed of in such manner as Landlord may see fit; provided, however, notwithstanding the foregoing, that Tenant will, upon request of Landlord made not later than thirty (30) days after the expiration or termination of the Term hereof, promptly remove from the Building any such personal property or, if any part thereof shall be sold, that Landlord may receive and retain the proceeds of such sale and apply the same, at its option, against the expenses of the sale, the cost of moving and storage, any arrears of Rent payable hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under Article 19 hereof or pursuant to law, with the balance if any, to be paid to Tenant.

21.           RIGHTS OF MORTGAGEES

21.1         Superiority of Lease. Except to the extent that it may be provided otherwise by written agreement between Tenant and a Mortgagee, this Lease shall be superior, and shall not be subordinated, to a Mortgage or to any other voluntary lien or encumbrance affecting the Land or Building or any part thereof and hereafter granted by Landlord. Any Mortgagee shall have the right, at its option, to subordinate its Mortgage to this Lease, in whole or in part, by recording a unilateral declaration to such effect.

21.2         Entry and Possession. Upon entry and taking possession of the Property by a Mortgagee, for the purpose of foreclosure or otherwise, such Mortgagee shall have all the rights of Landlord, and shall be liable to perform all the obligations of Landlord arising during the period of such possession, provided, however, that upon the return of possession to Landlord by such Mortgagee, such rights and obligations of Mortgagee shall cease until a subsequent entry.

21.3         Right to Cure. No act or failure to act on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, to be relieved of Tenant’s obligations hereunder or to terminate this Lease, shall result in a release or termination of such obligations or a termination of this Lease unless (i) Tenant shall have first given written notice of Landlord’s act or failure to act to first Mortgagees of record, if any, and to any other Mortgagees of whom Tenant has been given written notice, specifying the act or failure to act on the part of Landlord which could or would give basis to Tenant’s rights; and (ii) such Mortgagees, after receipt of such notice, have failed or refused to correct or cure the condition complained of within a

27

reasonable time thereafter, but nothing contained in this paragraph shall be deemed to impose any obligation on any such Mortgagees to correct or cure any such condition. “Reasonable time” as used above means and includes a reasonable time to obtain possession of the Land and Building if any such Mortgagee elects to do so and a reasonable time to correct or cure the condition if such condition is determined to exist.

21.4         Prepaid Rent. No Rent shall be paid more than thirty (30) days prior to the due dates thereof and, as to a first Mortgagee of record and any other Mortgagees of whom Tenant has been given written notice, payments made in violation of this provision shall (except to the extent that such Rent is actually received by such Mortgagee) be a nullity as against such Mortgagee and Tenant shall be liable for the amount of such payments to such Mortgagee.

21.5         Continuing Offer. The covenants and agreements contained in this Lease with respect to the rights, powers and benefits of a Mortgagee (particularly, without limitation thereby, the covenants and agreements contained in this Article) constitute a continuing offer to any person, corporation or other entity, which by accepting or requiring an assignment of this Lease or by entry or foreclosure assumes the obligations herein set forth with respect to such Mortgagee; every such Mortgagee is hereby constituted a party to this Lease as an obligee hereunder to the same extent as though its name was written hereon as such; and such Mortgagee shall be entitled to enforce such provisions in its own name.

21.6         Subordination. Notwithstanding the foregoing provisions of this Article, Tenant agrees, at Landlord’s request, to execute and deliver promptly any certificate or other instrument which Landlord may request subordinating this Lease and all rights of Tenant hereunder to any Mortgage, and to all advances made under such Mortgage and/or agreeing to attorn to such Mortgagee in the event that it succeeds to Landlord’s interest in the Property, provided that the holder of any such Mortgage shall execute and deliver to Tenant a non-disturbance agreement to the effect that, in the event of any foreclosure of such Mortgage, such holder will not name Tenant as a party defendant to such foreclosure nor disturb its possession under the Lease and will otherwise recognize Tenant’s rights hereunder. Landlord warrants and represents that the Property is not presently subject to any Mortgage.

21.7         Limitations on Liability. Nothing contained in the foregoing Section 21.6 or in any such non-disturbance agreement or non-disturbance provision shall however, affect the prior rights of the holder of any Mortgage with respect to the proceeds of any award in condemnation or of any fire insurance policies affecting the Building, or impose upon any such holder any liability (i) for the erection or completion of the Building, or (ii) in the event of damage or destruction to the Building or the Demised Premises by fire or other casualty, for any repairs, replacements, rebuilding or restoration except such repairs, replacements, rebuilding or restoration as can reasonably be accomplished from the net proceeds of insurance actually received by, or made available to, such holder, or (iii) for any default by Landlord under the Lease occurring prior to any date upon which such holder shall become Tenant’s landlord, or (iv) for any credits, offsets or claims against the Rent as a result of any acts or omissions of Landlord committed or omitted prior to such date, or (v) for return of any security deposit or other funds unless the same shall have been received by such holder, and any such agreement or provision may so state.

28

22.           QUIET ENJOYMENT

Landlord covenants that if, and so long as, Tenant keeps and performs each and every covenant, agreement, term, provision and condition herein contained on the part and on behalf of Tenant to be kept and performed, Tenant shall quietly enjoy the Demised Premises from and against the claims of all persons claiming by, through or under Landlord subject, nevertheless, to the covenants, agreements, terms, provisions and conditions of this Lease and to all Mortgages to which this Lease is subject and subordinate.

Without incurring any liability to Tenant, Landlord may permit access to the Demised Premises and open the same, whether or not Tenant shall be present, upon any demand of any receiver, trustee, assignee for the benefit of creditors, sheriff, marshall or court officer entitled to, or reasonably purporting to be entitled to, such access for the purpose of taking possession of, or removing Tenant’s property or for any other lawful purpose (but this provision and any action by Landlord hereunder shall not be deemed a recognition by Landlord that the person or official making such demand has any right or interest in or to this Lease, or in or to the Demised Premises), or upon demand of any representative of the fire, police, building, sanitation or other department of the city, county, state or federal governments.

23.           ENTIRE AGREEMENT - WAIVER - SURRENDER

23.1         Entire Agreement. This Lease and the Exhibits made a part hereof contain the entire and only agreement between the parties and any and all statements and representations, written and oral, including previous correspondence and agreements between the parties hereto, are merged herein. Tenant acknowledges that all representations and statements upon which it relied in executing this Lease are contained herein and that Tenant in no way relied upon any other statements or representations, written or oral. Any executory agreement hereafter made shall be ineffective to change, modify, discharge or effect an abandonment of this Lease in whole or in part unless such executory agreement is in writing and signed by the party against whom enforcement of the change, modification, discharge or abandonment is sought. Nothing herein shall prevent the parties from agreeing to amend this Lease and the Exhibits made a part hereof as long as such amendment shall be in writing and shall be duly signed by both parties.

23.2         Waiver by Landlord. The failure of Landlord to seek redress for violation, or to insist upon the strict performance, of any covenant or condition of this Lease, or any of the Rules and Regulations promulgated hereunder, shall not prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by Landlord of Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of such Rules and Regulations against Tenant and/or any other tenant or subtenant in the Building shall not be deemed a waiver of any such Rules and Regulations. No provisions of this Lease shall be deemed to have been waived by Landlord unless such waiver be in writing signed by Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than the Rent herein stipulated shall be deemed to be other than on account of the stipulated Rent, 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

29

Landlord’s right to recover the balance of such Rent or pursue any other remedy in this Lease provided.

23.3         Surrender. No act or thing done by Landlord during the term hereby demised shall be deemed an acceptance of a surrender of the Demised Premises, and no agreement to accept such surrender shall be valid, unless in writing signed by Landlord. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Demised Premises prior to the termination of this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a surrender of the Demised Premises.

24.           INABILITY TO PERFORM - EXCULPATORY CLAUSE

Except as otherwise expressly provided in this Lease, this Lease and the obligations of Tenant to pay Rent hereunder and perform all other covenants, agreements, terms, provisions and conditions hereunder on the part of Tenant to be performed shall in no way be affected, impaired or excused because Landlord is unable to fulfill any of its obligations under this Lease or is unable to supply or is delayed in supplying any service expressly or impliedly to be supplied or is unable to make or is delayed in making any repairs, replacements, additions, alterations, improvements or decorations or is unable to supply or is delayed in supplying any equipment or fixtures if Landlord is prevented or delayed from doing so by reason of strikes or labor troubles or any other similar or dissimilar cause whatsoever beyond Landlord’s reasonable control, including but not limited to, governmental preemption in connection with a national emergency or by reason of any rule, order or regulation of any department or subdivision thereof of any governmental agency or by reason of the conditions of supply and demand which have been or are affected by war, hostilities or other similar or dissimilar emergency. In each such instance of inability of Landlord to perform, Landlord shall exercise reasonable diligence to eliminate the cause of such inability to perform.

Tenant shall neither assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than Landlord’s interest in the Property and in the rents, issues and profits thereof, and Tenant agrees to look solely to such interest for the satisfaction of any liability of Landlord under this Lease, it being specifically agreed that in no event shall Landlord (which term shall include, without limitation any of the officers, trustees, directors, partners, beneficiaries, joint venturers, members, stockholders or other principals or representatives, disclosed or undisclosed, of Landlord or any managing agent) ever be personally liable for any such liability. This paragraph shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or to take any other action which shall not involve the personal liability of Landlord to respond in monetary damages from Landlord’s assets other than the Landlord’s interest in said real estate, as aforesaid. In no event shall Landlord ever be liable for consequential damages. In no event shall Tenant be liable for consequential damages not expressly provided for in this Lease unless such damages are a reasonably foreseeable result of Tenant’s failure to fulfill its obligations hereunder.

30

25.           BILLS AND NOTICES

Any notice, consent, request, bill, demand or statement hereunder by either party to the other party shall be in writing and shall be either delivered or served personally or sent by certified mail, return receipt requested, in a postpaid envelope, deposited in the United States mails addressed to the respective party at its Address as stated in Article 1, or if any Address for notices shall have been duly changed as hereinafter provided, at such changed Address. Either party may at any time change the Address for such notices, consents, requests, bills, demands or statements by delivering or mailing, as aforesaid, to the other party a notice stating the change and setting forth the changed Address, provided such changed address is within the United States. Any such notice, consent, request, bill, demand or statement shall be effective when received or refused.

All bills and statements for reimbursement or other payments or charges due from Tenant to Landlord hereunder shall be due and payable in full thirty (30) days, unless herein otherwise provided, after submission thereof by Landlord to Tenant. Tenant’s failure to make timely payment of any amounts indicated by such bills and statements, whether for work done by Landlord at Tenant’s request, reimbursement provided for by this Lease or for any other sums properly owing by Tenant to Landlord, shall be treated as a default in the payment of Rent, in which event Landlord shall have all rights and remedies provided in this Lease for the nonpayment of Rent.

26.           PARTIES BOUND - SEIZIN OF TITLE

The covenants, agreements, terms, provisions and conditions of this Lease shall bind and benefit the successors and assigns of the parties hereto with the same effect as if mentioned in each instance where a party hereto is named or referred to, except that no violation of the provisions of Article 14 hereof shall operate to vest any rights in any successor or assignee of Tenant and that the provisions of this Article shall not be construed as modifying the conditions of limitation contained in Article 19 hereof.

If in connection with or as a consequence of the sale, transfer or other disposition of the real estate (Land and/or Building, either or both, as the case may be) of which the Demised Premises are a part Landlord ceases to be the owner of the reversionary interest in the Demised Premises, Landlord shall be entirely freed and relieved from the performance and observance thereafter of all covenants and obligations hereunder accruing thereafter on the part of Landlord to be performed and observed (other than the duty to properly account for any security deposit held by Landlord pursuant to Section 27.7 until said deposit, or any balance thereof, is transferred to Landlord’s successor), it being understood and agreed in such event (and it shall be deemed and construed as a covenant running with the land) that the person succeeding to Landlord’s ownership of said reversionary interest shall thereupon and thereafter assume, and perform and observe, any and all of such covenants and obligations of Landlord.

27.           MISCELLANEOUS

27.1         Separability. If any provision of this Lease or portion of such provision or the application thereof to any person or circumstance is for any reason held invalid or unenforceable,

31

the remainder of the Lease (or the remainder of such provision) and the application thereof to other persons or circumstances shall not be affected thereby.

27.2         Captions. The captions are inserted only as a matter of convenience and for reference, and in no way define, limit or describe the scope of this Lease nor the intent of any provisions thereof.

27.3         Brokers. Each party represents and warrants that it has not directly or indirectly dealt, with respect to the leasing of space in the Building, with any broker or had its attention called to the Demised Premises or other space to let in the Building, by any broker other than the Brokers listed in Article 1, whose commission shall be the responsibility of Landlord. Each party agrees to exonerate and save harmless and indemnify the other against any claims for a commission by any other broker, person or firm, with whom such party has dealt in connection with the execution and delivery of this Lease or out of negotiations between Landlord and Tenant with respect to the leasing of other space in the Building.

27.4         Governing Law. This Lease is made pursuant to, and shall be governed by, and construed in accordance with, the laws of the Commonwealth of Massachusetts.

27.5         Assignment of Lease and/or Rent. With reference to any assignment by Landlord of its interest in this Lease and/or the Rent payable hereunder, conditional in nature or otherwise, which assignment is made to or held by a bank, trust company, insurance company or other institutional lender holding a Mortgage on the Building, Landlord and Tenant agree:

(a)           that the execution thereof by Landlord and acceptance thereof by such Mortgagee shall never be deemed an assumption by such Mortgagee of any of the obligations of Landlord hereunder, unless such Mortgagee shall, by written notice sent to the Tenant, specifically otherwise elect; and

(b)           that, except as aforesaid, such Mortgagee shall be treated as having assumed the Landlord’s obligations hereunder only upon foreclosure of such Mortgagee’s Mortgage and the taking of possession of the Demised Premises after having given notice of its intention to succeed to the interest of Landlord under this Lease.

27.6         Notice of Lease. Neither party shall record this Lease in any Registry of Deeds or Registry District, provided however that either party shall at the request of the other, execute and deliver a recordable Notice of this Lease in the form prescribed by Chapter 183, Section 4 of the Massachusetts General Laws.

27.7         Security Deposit. A deposit in the amount of $596,122 shall be paid by Tenant upon execution hereof and held by Landlord as security for the full, faithful and punctual performance by Tenant of all the covenants of this Lease on Tenant’s part to be performed, it being understood that said deposit is not to be considered prepaid rent, nor shall damages be limited to the amount of said deposit, nor shall Landlord be required, because of said deposit, to waive its right under Article 19 to terminate this Lease in the event of default. In no event shall Landlord be obligated to pay interest on said deposit. Said deposit, or any balance thereof, shall be refunded to Tenant, subject to Tenant’s satisfactory compliance with its covenants hereunder,

32

within thirty (30) days following the end of the Term of this Lease. Tenant shall be entitled to pay said deposit, either initially or to replace a previous cash payment (it being understood that no further substitutions in the form of said deposit shall be allowed), by furnishing an irrevocable letter of credit subject to the following terms and conditions. Said letter of credit shall be issued by a commercial bank approved by Landlord and shall be in form and content satisfactory in all respects to Landlord. In the event of any default by Tenant, Landlord shall be entitled to receive from the issuer of such letter of credit upon demand so much of the amount which may be drawn therefrom as shall be necessary to cure such default and compensate Landlord for all losses, liabilities, damages and other expenses, including without limitation reasonable attorneys’ fees, which may be imposed upon, incurred by or asserted against Landlord by reason of such default, and Tenant shall thereafter promptly restore such letter of credit to its original amount. If Tenant fails to restore such letter of credit to its original amount as hereinabove required, or if such letter of credit is about to expire and shall not have been renewed as herein required within thirty (30) days preceding such expiration, or if Landlord otherwise reasonably deems itself insecure with regard to the performance by Tenant of its covenants hereunder, then in any such event Landlord may upon demand withdraw all remaining available funds under such letter of credit and hold the same as a cash security deposit pursuant to the preceding provisions of this Section.

27.8         Parking. So long as this Lease remains in full force and effect, Landlord shall allocate to Tenant nine (9) unreserved spaces in the parking area to be contained in the Building.  Tenant shall comply with all regulations of general applicability imposed by Landlord with respect to the use of such spaces by Tenant hereunder, including without limitation payment of such fees as may be generally applicable from time to time, calculated at the same monthly rate applicable from time to time to spaces located in the garage at 10 Necco Street, Boston, Massachusetts (or, if Landlord no longer owns or operates said garage, at the same monthly rate applicable from time to time to spaces located in any comparable garage facility designated by Landlord). To the fullest extent permitted by law, Landlord shall have no responsibility for securing such parking area, nor shall Landlord be liable for any theft, injury or damage occurring therein.

33

IN WITNESS WHEREOF, Landlord and Tenant have caused this instrument to be executed under seal, all as of the day and year first above written.
