In addition, Tenant shall reimburse Landlord for the cost of any repairs to the Building necessitated by the acts or omissions of Tenant, its subtenants, assignees, invitees, employees, contractors and agents, to the extent Landlord is not reimbursed for such costs under its insurance policies. Subject to the preceding sentence, Landlord shall perform any maintenance or make any repairs to the Building as Landlord shall desire or deem necessary for the safety, operation or preservation of the Building, or as Landlord may be required or requested to do by any governmental authority or by the order or decree of any court or by any other proper authority. Except as otherwise provided in Sections 12 and 13 below and subject to Tenant's obligations set forth in the preceding paragraph or elsewhere in this Lease, Landlord shall keep and maintain or cause to be kept and maintained the structural components of the Building (including, without limitation, the roof and the roof membrane), all common areas of the Property, and all Building systems (excluding only those non-standard portions of Building systems which are located within a tenant's premises and service only such tenant's premises) in a neat, safe and orderly condition and shall make all necessary repairs thereto. Except as otherwise provided in this Lease, the cost of all such maintenance shall be borne by Landlord and shall be included as part of Expenses. 9. ALTERATIONS A. Requirements. Tenant shall not make any replacement, alteration, ------------ improvement or addition to or removal from the Premises (collectively an "alteration") costing more than $5,000 to complete without the prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed. In the event Tenant proposes to make any alteration, Tenant shall, prior to commencing such alteration, submit to Landlord for prior written approval: (i) detailed plans and specifications; (ii) sworn statements, including the names, addresses and copies of contracts for all contractors; (iii) all necessary permits evidencing compliance with all applicable governmental rules, regulations and requirements; (iv) certificates of insurance in form and amounts required by Landlord, naming Landlord and any other parties designated by Landlord as additional insureds; and (v) all other documents and information as Landlord may reasonably request in connection with such alteration. Tenant agrees to pay Landlord's standard charges for review of all such items and supervision of the alteration, which charge as of the date of this Agreement is five (5%) percent of the cost of the alteration. Neither approval of the plans and specifications nor supervision of the alteration by Landlord shall constitute a representation or warranty by Landlord as to the accuracy, adequacy, sufficiency or propriety of such plans and specifications or the quality of workmanship or the compliance of such alteration with applicable law. Tenant shall pay the entire cost of the alteration and, if reasonably requested by Landlord, shall deposit with Landlord prior to the commencement of the alteration, security for the payment and completion of the alteration in form and amount required by Landlord. Each alteration shall be performed in a good and workmanlike manner, in accordance with the plans and specifications approved by Landlord, and shall meet or exceed the standards for construction and quality of materials established by Landlord for the Building. In addition, each alteration shall be performed in compliance with all applicable governmental and insurance company laws, regulations and requirements. Each alteration shall be performed by union contractors if reasonably required by Landlord and in harmony with Landlord's employees, contractors and other tenants. Each alteration, whether temporary or permanent in character, made by Landlord or Tenant in or upon the Premises (excepting only Tenant's furniture, equipment and trade fixtures) shall become Landlord's property and shall remain upon the Premises at the expiration or termination of this Lease without compensation to Tenant; provided, however, that Landlord shall have the right to require Tenant to remove such alteration at Tenant's sole cost and expense in accordance with the provisions -11- of Section 15 of this Lease. Notwithstanding the foregoing, in the event of any permitted alteration costing Tenant more than $100,000 to fully complete, Landlord shall notify Tenant prior to Tenant's commencing such alteration work whether Landlord shall require removal of such alteration by Tenant at the end of the Term, and Tenant shall be entitled to rely on such notice. Tenant acknowledges that the Premises may constitute a place of public accommodation or a commercial facility under Title III of the Americans with Disabilities Act (the "ADA") and that the ADA is applicable to both an owner and a lessee of a place of public accommodation or commercial facility. Tenant further acknowledges that under the ADA any alteration to the Premises must comply with accessibility standards set forth in the rules promulgated by the Department of Justice at 28 C.F.R. 36. 101 et. seq. Notwithstanding anything in this Lease to the contrary, in the event Tenant makes any alteration to the Premises or conducts itself in a manner which would require compliance with Title III of the ADA and the accessibility standards promulgated by the Department of Justice, Tenant agrees to design and build such alterations to the Premises and/or to conduct itself in such a fashion as to comply with the ADA and the accessibility standards. B. Liens. Upon completion of any alteration, Tenant shall promptly ----- furnish Landlord with sworn owner's and contractors statements and full and final waivers of lien covering all labor and materials included in such alteration. Tenant shall not permit any mechanic's lien to be filed against the Building, or any part thereof, arising out of any alteration performed, or alleged to have been performed, by or on behalf of Tenant. If any such lien is filed, Tenant shall within ten (10) days thereafter (or such shorter period as required by the terms of any mortgage, provided Tenant has received notice of such shorter period) have such lien released of record or deliver to Landlord a bond in form, amount, and issued by a surety satisfactory to Landlord, indemnifying Landlord and the holder of a mortgage (a "mortgagee") against all costs and liabilities resulting from such lien and the foreclosure or attempted foreclosure thereof. If Tenant fails to have such lien so released or to deliver such bond to Landlord, Landlord or a mortgagee, without investigating the validity of such lien, may pay or discharge the same; and Tenant shall reimburse Landlord or the mortgagee, as applicable, upon demand for the amount so paid by Landl6rd or the mortgagee, including Landlord's reasonable and actual expenses and attorneys' fees. 10. INSURANCE A. Tenant's Insurance. Tenant, at its expense, shall maintain at all ------------------ times during the Term the following insurance policies: (i) all risk or equivalent special form coverage insuring the full replacement cost of all improvements, alterations or additions to the Premises made at Tenant's expense, and all other property owned or used by Tenant and located in the Premises; (ii) commercial general liability insurance, contractual liability insurance and property damage insurance with respect to the Building and the Premises, with limits to be set by Landlord from time to time but in any event not less than $3,000,000.00 combined single limit for personal injury, sickness or death or for damage to or destruction of property for any one occurrence; and (iii) insurance against such other risks and in such other amounts as Landlord may from time to time reasonably require. The form of all such policies and deductibles thereunder shall be subject to Landlord's prior reasonable approval. All such policies shall be issued by insurers reasonably acceptable to Landlord and licensed to do business in The Commonwealth of Massachusetts and shall contain a waiver of any rights of subrogation thereunder. In addition, the policies shall name Landlord, the mortgagee and its agents, and any other parties designated by Landlord as additional insureds, shall require at least thirty (30) days' prior written notice to Landlord, the mortgagee, and such other parties designated by Landlord of termination or modification and shall be primary and not contributory. Tenant shall at least fifteen (15) days prior to the Commencement Date, and within fifteen (15) days prior to the expiration of each such policy, deliver to Landlord either a duplicate original of all insurance -12- policies required to be maintained by Tenant hereunder or Evidence of Insurance (in form ACORD 27 or its equivalent) for each such policy evidencing the foregoing insurance or renewal thereof, as the case may be. B. Landlord's Insurance. Landlord shall take out and maintain in force -------------------- throughout the Term, in a company or companies authorized to do business in The Commonwealth of Massachusetts, (i) casualty insurance on the Building in an amount equal to the full replacement value of the Building (exclusive of foundations), covering all risks of direct physical loss or damage and so-called "extended coverage" risks and (ii) commercial general liability insurance with respect to the Building and Property in such amounts as Landlord may from time to time deem necessary or desirable. Any insurance required to be maintained by Landlord hereunder may be maintained in the form of a blanket policy covering the Building as well as other properties owned by Landlord or affiliates of Landlord so long as the blanket policy does not reduce the limits nor diminish the coverage required herein. 11. WAIVER AND INDEMNITY. A. Waiver. Tenant releases Landlord, its property manager and their ------ respective agents and employees from, and waives all claims for, damage or injury to person or property and loss of business sustained by Tenant and resulting from the Building or the Premises or any part thereof or any equipment therein becoming in disrepair, or resulting from any accident in or about the Building. This paragraph shall apply particularly, but not exclusively, to flooding, damage caused by Building equipment and apparatus, water, snow, frost, steam, excessive heat or cold, broken glass, sewage, gas, odors, excessive noise or vibration or the bursting or leaking of pipes, plumbing fixtures or sprinkler devices. Without limiting the generality of the foregoing, Tenant waives all claims and rights of recovery against Landlord, its property manager and their respective agents and employees for any loss or damage to any property of Tenant, which loss or damage is insured against, or required to be insured against, by Tenant pursuant to Section 10 above, whether or not such loss or damage is due to the fault or negligence of Landlord, its property manager or their respective agents or employees, and regardless of the amount of insurance proceeds collected or collectible under any insurance policies in effect. B. Indemnity. Tenant agrees to indemnify, defend and hold harmless --------- Landlord, its property manager and their respective agents and employees, from and against any and all claims, demands, actions, liabilities, damages, costs and expenses (including attorneys' fees), for injuries to any persons and damage to or theft or misappropriation or loss of property occurring in or about the Building and arising from the use and occupancy of the Premises or from any activity, work, or thing done, permitted or suffered by Tenant in or about the Premises (including, without limitation, any alteration by Tenant) or from any breach or default on the part of Tenant in the performance of any covenant or agreement on the part of Tenant to be performed under this Lease or due to any other act or omission of Tenant, its subtenants, assignees, invitees, employees, contractors and agents. Without limiting the foregoing, Tenant shall indemnify, defend and hold Landlord harmless from any claims, liabilities, damages, costs and expenses arising out of the use or storage of hazardous or toxic materials in the Building by Tenant. If any such proceeding is filed against Landlord or any such indemnified party, Tenant agrees to defend Landlord or such party in such proceeding at Tenant's sole cost by legal counsel reasonably satisfactory to Landlord, if requested by Landlord. 12. FIRE AND CASUALTY A. Obligation to Repair or Rebuild. If the Premises or the Building ------------------------------- shall be damaged or destroyed by fire or other casualty, Tenant shall promptly notify Landlord of any damage or destruction to the Premises of which Tenant has knowledge or is aware, and Landlord, subject to its mortgagee's consent and to the conditions -13- set forth in this Section 12, shall repair, rebuild or replace such damage and restore the Premises and/or the Building, subject to Section 12(D) and Section 12(F) below, to substantially the same condition in which they were immediately prior to such damage or destruction including restoration of the Base Building Elements (as defined in the Work Letter attached hereto as Exhibit D, but specifically excluding items (vii) and (viii) thereof); provided, however, that Landlord shall only be obligated to restore such damage which is covered by its fire and all risk insurance policy or policies. B. Commencement and Completion of Work. The work shall be commenced ----------------------------------- promptly and co~ipleted with due diligence, taking into account the time required by Landlord to effect a settlement with, and procure insurance proceeds from, the insurer, and for delays beyond Landlord's reasonable control. C. Application of Proceeds. The net amount of any insurance proceeds ----------------------- (excluding proceeds received pursuant to any rental interruption coverage obtained by Landlord), recovered by reason of the damage or destruction of the Building in excess of the cost of adjusting the insurance claim and collecting the insurance proceeds (such excess amount being hereinafter called the "net insurance proceeds") shall be applied towards the reasonable cost of the work required to be performed by Landlord under this Section 12. If the net insurance proceeds are more than adequate to complete such work, the amount by which the net insurance proceeds exceed the cost of such work shall be retained by Landlord. D. Tenant's Personal Property and Alterations. Landlord's obligation or ------------------------------------------ election to restore the Premises under this Section 12 shall not include the repair, restoration or replacement of the furniture or any other personal property owned by or in the possession of Tenant. In addition, Landlord shall not be under any obligation to repair, restore or replace any alterations or improvements to the Premises made by or on behalf of Tenant. E. Abatement of Rent. Tenant will receive an abatement of Rent to the ----------------- extent and during the time the Premises are rendered untenantable due to a fire or other casualty, such Rent to abate in such proportion as the part of the Premises thus destroyed or rendered untenantable bears to the total Premises from the date of such damage or destruction and until the earlier of the date that (i) Landlord obtains a certificate of occupancy with respect to completion of the work upon the Premises required to be performed by Landlord under this Section 12 or (ii) Tenant recommences use of such part of the Premises and, in cases in which the Premises are being restored by Landlord, to be conditioned upon Tenant not occupying such part of the Premises for the conduct of business. If the Premises are so slightly damaged by such fire or other casualty as not to be rendered in any part unteriantable, Landlord shall complete the work upon the Premises required to be performed by Landlord under this Section 12 with reasonable promptness and the payment of Rent shall not be affected thereby. Tenant shall, at its own cost and expense, remove so much of its furniture and furnishings and other belongings from the Premises as Landlord shall require in order to perform the work required to be performed by Landlord under this Section 12. F. Landlord's Option Not to Restore. Notwithstanding any of the -------------------------------- foregoing provisions of this Section 12 to the contrary, if there is substantial damage to the Building due to a fire or other casualty, or if, in the judgment of Landlord's architect, damage to the Premises due to a fire or other casualty is such that the work upon the Premises required to be performed by Landlord under this Section 12 with respect to such fire or other casualty cannot be completed within ninety (90) days after such fire or other casualty, then Landlord shall have the option not to perform the work upon the Premises required to be performed by Landlord under this Section 12 with respect to such fire or other casualty, and may elect to terminate this Lease by sending a written notice of -14- such termination to Tenant, the notice to specify a termination date not less than thirty (30) days after its transmission. Landlord shall notify Tenant in writing within sixty (60) days after the date of such fire or other casualty of such architect's estimate of the period of time required to perform the work upon the Premises required to be performed by Landlord with respect to such fire or other casualty. G. Tenant's Right to Terminate. Notwithstanding anything herein to the --------------------------- contrary, if the Premises are damaged by a fire or other casualty, then (i) if the fire or other casualty occurs prior to the date which is two hundred seventy (270) before the Expiration Date (as it may be extended pursuant to the Tenant's Renewal Option) and if Landlord fails to complete the work upon the Premises required to be performed by Landlord under this Section 12 with respect to such fire or other casualty within two hundred seventy (270) days after such fire or other casualty, Tenant may terminate this Lease by notice given to Landlord at any time after the end of such two hundred seventy (270) day repair period but prior to the date that Landlord has completed the work upon the Premises required to be performed under this Section 12 with respect to such fire or other casualty, and (ii) if the fire or other casualty occurs within two hundred seventy (270) days of the Expiration Date (as it may be extended pursuant to the Tenant's Renewal Option) and if as a consequence of such fire or other casualty the Premises are rendered substantially unusable, the Tenant may terminate this Lease by notice given to Landlord within thirty (30) days of the date on which the fire or other casualty occurs. 13. CONDEMNATION. If the Premises or the Building is rendered untenantable by reason of a condemnation (or by a deed given in lieu thereof), then either party may terminate this Lease by giving written notice of termination to the other party within thirty (30) days after such condemnation, in which event this Lease shall terminate effective as of the date of such condemnation. If this Lease so terminates, Rent shall be paid through and apportioned as of the date of such condemnation. If such condemnation does not render the Premises or the Building untenantable, this Lease shall continue in effect and Landlord shall promptly restore the portion not condemned to the extent reasonably possible to the condition existing prior to the condemnation. In such event, however, Landlord shall not be required to expend an amount in excess of the proceeds received by Landlord from the condemning authority. Landlord reserves all rights to compensation for any condemnation (except for any awards payable directly to Tenant for relocation expenses and except for any award for alterations to the Premises paid for by Tenant except to the extent any such award diminishes the award payable to Landlord on account of any such condemnation). Tenant hereby assigns to Landlord any right Tenant may have to such compensation (except as provided in the immediately preceding sentence), and Tenant shall make no claim against Landlord or the condemning authority for compensation (except as provided in the immediately preceding sentence) for termination of Tenant's leasehold interest under this Lease or interference with Tenant's business. 14. ASSIGNMENT AND SUBLETTING. A. Landlord's Consent. Tenant shall not, without the prior written ------------------ consent of Landlord: (i) assign, convey, mortgage or otherwise transfer this Lease or any interest hereunder, or sublease the Premises, or any part thereof, whether voluntarily or by operation of law; or (ii) permit the use of the Premises or any part thereof by any person other than Tenant and its employees. Any such transfer, sublease or use described in the preceding sentence (herein referred to as a "Transfer", which term shall include any reassignment of this Lease after any initial assignment of this Lease by the Tenant named herein, or any subsequent reassignment and any assignment of any sublease with respect to all or any portion of the Premises and any subsubleasing of any portion of the Premises previously subleased) occurring without the prior written consent of Landlord shall be void and of no -15- effect. Landlord's consent to any Transfer shall not constitute a waiver of Landlord's right to withhold its consent to any future Transfer. Landlord's consent to any Transfer or acceptance of rent from any party other than Tenant shall not release Tenant from any covenant or obligation under this Lease. Landlord may require as a condition to its consent to any assigninent of this Lease that the assignee execute an instrument in which such assignee assumes the obligations of Tenant hereunder. For the purposes of this paragraph, the transfer (whether direct or indirect) of all or substantially all of Tenant's assets (including Tenant's interest under this Lease), all or a majority of the capital stock in a corporate Tenant (whether by private sale or public offering of such stock), or the merger, consolidation or reorganization of such Tenant, or the transfer of all or any general partnership interest in any partnership Tenant, shall not be considered a Transfer provided that (exrept in case of a public offering of stock of a corporate Tenant) the Transferee of such assets or interest shall in all events have a positive net worth, as reasonably determined by Landlord. B. Standards for Consent. If Tenant desires the consent of Landlord to --------------------- a Transfer, Tenant shall submit to Landlord, at least forty-five (45) days prior to the proposed effective date of the Transfer, a written notice which includes such information as Landlord may require about the proposed Transfer and the transferee. If Landlord does not terminate this Lease, in whole or in part, pursuant to Section 14(C), Landlord shall not unreasonably withhold its consent to any assignment or sublease. Landlord shall provide Tenant with notice of its grant or withholding of consent within thirty (30) days of receipt of Tenant's notice described in the first sentence of this Section 14(B). Landlord shall not be deemed to have unreasonably withheld its consent if, in the judgment of Landlord (without implied limitation): (i) the transferee is of a character or engaged in a business which is not in keeping with the standards or criteria used by Landlord in leasing the Building; (ii) the financial condition of the transferee is such that it may not be able to perform its obligations in connection with this Lease; (iii) the purpose for which the transferee intends to use the Premises or portion thereof is in violation of the terms of this Lease or the lease of any other tenant in the Building; (iv) the transferee is a current tenant of the Building or is a user who is then, or has at any time during the Term been, in negotiations with Landlord for space at the Property and such transferee's space needs could be accommodated by space available in the Building under a direct lease from Landlord; (v) the rent to be charged the transferee is less than the then fair market rental value of space in the Building (which fair market rental value shall be deemed to be the rent set forth in the most current lease by Landlord of space in the Building); or (vi) consent to the Transfer would violate the terms and provisions of a mortgage. If Landlord wrongfully withholds its consent to any Transfer, Tenant's sole and exclusive remedy therefor shall be to seek specific performance of Landlord's obligation to consent to such Transfer. If Landlord consents to any Transfer, Tenant shall pay to Landlord one hundred percent (100%) of all rent and other consideration received by Tenant in excess of the Rent paid by Tenant hereunder for the portion of the Premises so transferred(after first deducting therefrom all reasonable costs incurred by Tenant in connection therewith, including, without limitation, reasonable legal, brokerage, space planning, and construction costs in connection therewith, proviaed, however, that at Landlord's option, Landlord shall have the right to require Tenant to deduct such costs by amortizing such costs on a straight-line basis over the remaining Term of the Lease (and including any Renewal Term, if so exercised) in equal monthly amounts). Such rent shall be paid as and when received by Tenant. In addition, Tenant shall pay to Landlord any attorneys' fees and expenses incurred by Landlord in connection with any proposed Transfer, whether or not Landlord consents to such Transfer. C. Recapture. Landlord shall have the right to terminate this Lease as --------- to that portion of the Premises covered by a Transfer. Landlord may exercise such right to terminate by giving notice to Tenant at any time within thirty (30) days after the date on which Tenant has furnished to Landlord all of the items required under Section 14(B) above. If Landlord exercises such right to terminate, Landlord shall be entitled to recover -16- possession of, and Tenant shall surrender such portion of, the Premises (with appropriate dernising partitions erected at the expense of Tenant) on the later of (i) the effective date of the proposed Transfer, or (ii) ninety (90) days after the date of Landlord's notice of termination. In the event Landlord exercises such right to terminate, Landlord shall have the right to enter into a lease with the proposed transferee without incurring any liability to Tenant on account thereof. Notwithstanding the foregoing, Landlord's right to terminate this Lease shall not apply to a proposed sublease of some or all of the Phase 11 Premises or the Phase III Premises which sublease is entered into prior to June 30, 2000 and which sublease has a term (including any option periods) which extends to a date not later than June 30, 2001. D. No Release. In no event shall any Transfer release or relieve Tenant ---------- from its obligations to fully observe or perforin all of the terms, covenants and conditions of this Lease on its part to be observed or performed (including liability arising during any renewal term of this Lease or with respect to any expansion space included in the Premises). It is agreed that the liabilities and obligations of Tenant hereunder are enforceable either before, simultaneously with or after proceeding against any assignee, sublessee or other transferee of Tenant. 15. SURRENDER. Upon the expiration or earlier termination of the Term or Tenant's right to possession of the Premises (and subject to the provisions of Sections 12 and 13 hereof), Tenant shall return the Premises to Landlord broom clean, and in good order and condition, ordinary wear only excepted. If Landlord requires Tenant to remove any alterations pursuant to Section 9 above, then such removal shall be done in a good and workmanlike manner; and, upon such removal, Tenant shall restore the Premises to its condition prior to the installation of such alterations. If Tenant does not remove such alterations after request to do so by Landlord, Landlord may remove the same and restore the Premises; and Tenant shall pay the cost of such removal and restoration to Landlord upon demand. Tenant shall also remove its furniture, equipment, trade fixtures and all other items of personal property from the Premises prior to the expiration or earlier termination of the Term or Tenant's right to possession of the Premises. If Tenant does not remove such items prior to the expiration or earlier termination of the Term or Tenant's right to possession of the Premises, Tenant shall be conclusively presumed to have conveyed the same to Landlord without further payment or credit by Landlord to Tenant; or at Landlord's sole option such items shall be deemed abandoned, in which event Landlord may cause such items to be removed and disposed of at Tenant's expense, without notice to Tenant and without obligation to compensate Tenant. 16. DEFAULTS AND REMEDIES. A. Default. The occurrence of any of the following shall constitute a ------- default (a "Default") by Tenant under this Lease: (i) Tenant fails to pay any Rent when due and such failure to pay is not cured within five (5) days after written notice from Landlord; however, a Default shall occur without any obligation of Landlord to give any notice if Landlord has given Tenant written notice under this Section 16(A)(i) on more than two (2) occasions during the twelve (12) month interval preceding such failure to pay by Tenant; (ii) Tenant fails to perform or observe any other covenant or obligation of Tenant set forth in this Lease and such failure to perforin is not cured within thirty (30) days (or iminediately if the failure involves a hazardous condition) after notice from Landlord, or, in the case of -17- a failure to observe any other covenant or obligation of Tenant set forth in this Lease which is not reasonably curable within thirty (30) days after notice from Landlord, Tenant fails to commence the cure of such failure promptly upon receipt of notice from Landlord to Tenant, or Tenant fails continuously to prosecute the cure of such failure, or Tenant fails to achieve such cure within ninety (90) days after such notice from Landlord to Tenant; (iii) the leasehold interest of Tenant is levied upon or attached under process of law and is not removed or bonded over to the satisfaction of Landlord within thirty (30) days; (iv) Tenant or any guarantor of this Lease dies or dissolves; (v) Tenant abandons or vacates the Premises; or (vi) any voluntary or involuntary proceedings are filed by or against Tenant or any guarantor of this Lease under any bankruptcy, insolvency or similar laws and, in the case of any involuntary proceedings, are not dismissed within sixty (60) days after filing. Notwithstanding any of the foregoing provisions of this Section 16(A) to the contrary, no notice of the opportunity to cure a failure to perform or observe any covenant or obligation of Tenant set forth in thi-s Lease need be given, and no cure period whatsoever with respect thereto shall be allowed to Tenant, if the failure to perform or observe is incurable. B. Right of Re-Entry. Upon the occurrence of a Default, Landlord may ----------------- elect to terminate this Lease, or, without terminating this Lease, terminate Tenant's right to possession of all or any portion of the Premises, in either case by written notice thereof to Tenant. Upon any such termination, Tenant shall immediately surrender and vacate the Premises and deliver possession thereof to Landlord. Tenant grants to Landlord the right, without notice to Tenant, to enter and repossess the Premises and to expel Tenant and any others who may be occupying the Premises and to remove any and all property therefrom, without being deemed in any manner guilty of trespass and without relinquishing Landlord's rights to Rent or any other right given to Landlord hereunder or by operation of law. C. Reletting. If Landlord terminates Tenant's right to possession of the --------- Premises without terminating this Lease, Landlord may relet the Premises or any part thereof In such case, Landlord shall use reasonable efforts to relet the Premises on such terms as Landlord shall reasonably deem appropriate; provided, however, Landlord may first lease Landlord's other available space and shall not be required to accept any tenant offered by Tenant or to observe any instructions given by Tenant about such reletting. Tenant shall reimburse Landlord for the costs and expenses of reletting the Premises including, but not limited to, all brokerage, advertising, legal, alteration and other expenses incurred to secure a nov; tenant for the Premises. In addition, if the consideration collected by Landlord upon any such reletting, after payment of the expenses of reletting the Premises which have not been reimbursed by Tenant, is insufficient to pay monthly the full amount of the Rent, Tenant shall pay to Landlord the amount of each monthly deficiency as it becomes due. If such consideration is greater than the amount necessary to pay the full amount of the Rent, the full amount of such excess shall be retained by Landlord and shall in no event be payable to Tenant. -18- D. Termination of Lease. If Landlord terminates this Lease pursuant to -------------------- the terms and provisions of this Section 16, Landlord may recover from Tenant and Tenant shall pay to Landlord, on demand, the Rent and other charges payable by Tenant to Landlord through the date of termination, and, in addition, shall pay to Landlord as damages, at the election of Landlord, either: (x) an accelerated lump sum amount equal to the present value (calculated using a discount rate equal to Landlord's reasonable estimate of the yield, as of the date of termination, produced by United States Treasury general obligation bills or notes (as the case may be) maturing on the date nearest in time to the Expiration Date) of the amount by which Landlord's reasonable estimate of the aggregate amount of Rent owing from the date of such termination through the Expiration Date plus Landlord's reasonable estimate of the aggregate expenses of reletting the Premises exceeds Landlord's reasonable estimate of the fair rental value of the Premises for the same period (after deducting from such fair rental value the time needed to relet the Premises and the amount of concessions which would normally be given to a new tenant); 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 Expiration Date; provided, however, if Landlord shall re-let the Premises during such period, then 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 tenninating this Lease, as well as the expenses of re-letting, including altering and preparing the Premises for new tenants, brokerage commissions, and all other similar and dissimilar expenses properly chargeable against the Premises and the rental therefrom, it being understood that any such re-letting rday be for a period equal to or shorter or longer than the remaining Tenn 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 or 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 Premises or any part thereof shall be re-let in combination with other space, a proper apportionment on a square foot area basis shall be made of the rent received from re-letting and other expenses of such reletting. 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. E. Other Remedies. At Landlord's election, and notwithstanding any -------------- subsequent or intervening cure thereof, Tenant's Default shall excuse Landlord from its obligations to deliver the Phase II or Phase III Premises to Tenant and/or to make any advance of funds to Tenant under the Work Letter, provided, however, that if Landlord shall elect to exercise either such remedy, Landlord shall be deemed to have elected to terminate the Lease as provided in Section 16(D) hereof. Further, Landlord may but shall not be obligated to perfonn any obligation of Tenant under this Lease; and, if Landlord so elects, all costs and expenses paid by Landlord in performing such obligation, together with interest at the Default.Rate, shall be reimbursed by Tenant to Landlord on demand. Any and all remedies set forth in this Lease: (i) shall be in addition to any and all other remedies Landlord may have at law or in equity, (ii) shall be cumulative, and (iii) may be pursued successively or concurrently as Landlord may elect. The exercise of any remedy by Landlord shall not be deemed an election of remedies or preclude Landlord from exercising any other remedies in the future. -19- F. Bankruptcy.

Tenant shall also pay, indemnify and defend Landlord from and against all claims and damages, consequential as well as direct, sustained by reason of Tenant's holding over. In addition, at any time while Tenant remains in possession, Landlord may elect instead, by written notice to Tenant and not otherwise, to have such retention of possession constitute a renewal of this Lease for one (1) year for the fair market rental value of the Premises as reasonably determined by Landlord but in no event less than the Rent payable immediately prior to such holding over. The provisions of this Section do not waive Landlord's right of re-entry or right to regain possession by actions at law or in equity or any other rights hereunder, and any receipt of payment by Landlord shall not be deemed a consent by Landlord to Tenant's remaining in possession or be construed as creating or renewing any lease or right of tenancy between Landlord and Tenant. 18. ESTOPPEL CERTIFICATES. A. Tenant agrees that, from time to time upon not less than ten (10) business days' prior request by Landlord, Tenant shall execute and deliver to Landlord a written certificate certifying: (a) that this Lease is unmodified and in full force and effect (or if there have been modifications, a description of such modifications and that this Lease as modified is in full force and effect); (b) the dates to which Rent has been paid; (c) that Tenant is in possession of the Premises, if that is the case; (d) that Landlord is not in default under this Lease, or, if Tenant believes Landlord is in default, the nature thereof in detail; (e) that Tenant has no off-sets or defenses to the performance of its obligations under this Lease (or if Tenant believes there are any off-sets or defenses, a full and complete explanation thereof); and (f) such additional matters as may be requested by Landlord, it being agreed that such certificate may be relied upon by any prospective purchaser, mortgagee or other person having or acquiring an interest in the Building. If Tenant fails to execute and deliver any such certificate within ten (10) business days after request, Tenant shall be deemed to be in Default of its obligations under the Lease and Landlord shall have the remedies provided hereunder and at law and in equity for such Default. B. Landlord agrees that, upon not less than thirty (30) days prior request by Tenant, and no more than once every twelve (12) months, Landlord shall execute and deliver to Tenant a certificate providing the certifications set forth in clauses (a)-(e) above (adjusted as applicable to Landlord), provided, however, that such certifications shall be qualified to Landlord's - -------- knowledge and belief, and in no event shall Landlord be estopped or barred from asserting facts contrary to such certifications in any proceeding (including, without limitation, in any litigation involving this Lease, Tenant or any successor to Tenant's interest under this Lease) so long as such contrary facts are based on circumstances first arising after the date of the certification or circumstances which were concealed from Landlord by Tenant,. -20- 19. SUBORDINATION. This Lease is and shall be expressly subject and subordinate at all times to (a) any present or future ground, underlying or operating lease of the Building, and all amendments, renewals and modifications to any such lease, and (b) the lien of any present or future mortgage or deed of trust encumbering fee title to the Building and/or the leasehold estate under any such lease. If any such mortgage or deed of trust shall be foreclosed, or if any such lease shall be terminated, the mortgagee, beneficiary or lessor, as the case may be, shall recognize the Tenant's interest in the Lease and the Tenant shall attorn to the purchaser at the foreclosure sale or to the lessor under such lease, subject to and in accordance with the terms of this Lease. Any such purchaser or lessor, shall not be: (i) subject to any credits, offsets, defenses, claims," counterclaims or demands that Tenant might have against any prior landlord (including, without limitation, Landlord); (ii) bound by any previous modification or amendment of the Lease or by any rent or additional rent that Tenant might have paid for more than the current month to any prior landlord, unless such modification or prepayment shall have been made with the prior written consent of the mortgagee, purchaser (after such purchaser has succeeded to the interest of the mortgagee or landlord) or lessor, as applicable; (iii) liable for any accrued obligation, act or omission of any prior landlord (including, without limitation, Landlord), whether prior to or after foreclosure or termination of the superior lease, as the case may be; (iv) bound by any covenant to undertake or complete any improvements to the Building or the Premises, or to reimburse or pay Tenant for the cost of any such improvement; (v) required to perform or provide any services not related to possession or quiet enjoyment of the Premises; or (vi) required to account for any security deposit other than any security deposit actually delivered to such successor. The foregoing provisions are declared to be self-operative and no further instruments shall be required to effect such subordination and/or attornment; provided, however, that upon Tenant's request Landlord shall request from any such mortgagee, beneficiary or lessor (and Tenant, upon the request of any such mortgagee, beneficiary, lessor or purchaser at foreclosure, as the case may be, agrees to execute) such subordination and/or attornment instruments as may be required by such person to confirm such subordination and/or attornment on the form customarily used by such party. Notwithstanding the foregoing to the contrary, any such mortgagee, beneficiary or lessor may elect to give the rights and interests of Tenant under this Lease (excluding rights in and to insurance proceeds and condemnation awards) priority over the lien of its mortgage or deed of trust or the estate of its lease, as the case may be. In the event of such election and upon the mortgagee, beneficiary or lessor notifying Tenant of such election, the rights and interests of Tenant shall be deemed superior to and to have priority over the lien of said mortgage or deed of trust or the estate of such lease, as the case may be, whether this Lease is dated prior to or subsequent to the date of such mortgage, deed of trust or lease. In such event, Tenant shall execute and deliver whatever instruments may be required by such mortgagee, beneficiary or lessor to confirm such superiority on the form customarily used by such party. If Tenant fails to execute any instrument required to be executed by Tenant under this Section 19 within ten (10) days after request, Tenant shall be deemed to be in Default of its obligations under the Lease and Landlord shall have the remedies provided hereunder and at law and in equity for such Default. As long as any mortgage is outstanding, Tenant agrees that Tenant shall not cancel, surrender, terminate, or enter into any agreement to cancel, surrender or terminate the Lease, without the prior written approval of such mortgagee. In the event of any default on the part of Landlord, arising out of or accruing under the Lease, whereby the validity or the continued existence of the Lease might be impaired or terminated by Tenant, or Tenant might have a claim for partial or total eviction or abatement of rent, Tenant shall not pursue any of its rights with respect to such default or claim, and no notice of termination of the Lease as a result of such default shall be effective, unless and until Tenant has given written notice of such default or claim to the applicable -21- mortgage (but not later than the time that Tenant notified Landlord of such default or claim) and granted to such mortgagee a reasonable time, which shall not be less than the greater of (i) the period of time granted to Landlord under the Lease, or (ii) thirty (30) days, after the giving of such notice by Tenant to such mortgagee, to cure or to undertake the elimination of the basis for such default or claim, after the time when Landlord shall have become entitled under the Lease to cure the cause of such default or claim; it being expressly understood that (a) if such default or claim cannot reasonably be cured within such cure period, such mortgagee shall have such additional period of time to cure same as it reasonably determines is necessary, so long as it continues to pursue such cure with reasonable diligence, and (b) such mortgagee's right to cure any such default or claim shall not be deemed to create any obligation for such mortgagee to cure or to undertake the elimination of any such default or claim. 20. QUIET ENJOYMENT. As long as no Default exists, which remains uncured, Tenant shall peacefully and quietly have and enjoy the Premises for the Tenn, free from interference by Landlord, subject, however, to the provisions of this Lease. The loss or reduction of Tenant's light, air or view will not be deemed a disturbance of Tenant's occupancy of the Premises nor will it affect Tenant's obligations under this Lease or create any liability of Landlord to Tenant. 21. BROKER. Tenant and Landlord each represent (for themselves only) to the other that they have dealt only with the broker(s) set forth in Item 16 of the Schedule (the "Broker(s)") in connection with this Lease and that, insofar as either knows, no other broker negotiated this Lease or is entitled to any commission in connection herewith. Tenant and Landlord each agree to indemnify, defend and hold the other, and Landlord's asset manager, its property manager and their respective employees harmless from and against any claims for a fee or commission made by any broker, other than the Broker(s), claiming to have acted by or on behalf of Tenant or Landlord in connection with this Lease. Landlord shall be responsible for payment of the fees and commissions payable to the Brokers in connection with this Lease. 22. NOTICES. All notices and demands to be given by one party to the other party under this Lease shall be given in writing, mailed or delivered to Landlord or Tenant, as the case may be, at the address of each party set forth in the Schedule or at such other address as either party may hereafter designate. Notices shall be delivered by hand or by United States certified or registered mail, postage prepaid, return receipt requested, or by a nationally recognized overnight air courier service. Notices shall be considered to have been given upon the earlier to occur of actual receipt or refusal to accept delivery thereof. 23. PARKING. During the Term, Tenant shall be permitted to use at no cost to Tenant its allocable share of vehicular parking spaces in the parking areas designated by Landlord for use by Building tenants, subject to such reasonable terms, conditions and regulations as are from time to time applicable to authorized users of such parking areas. Tenant's allocable share of such parking spaces shall be 3.5 parking spaces per 1,000 square feet of rentable floor area within the Premises, i.e. two hundred fifty-four (254) parking spaces. Such parking spaces shall be available for Tenant's use on an unassigned, non- reserved basis. So long as Landlord elects to make available to tenants of the Building, as matter of management practice, space in the Landlord's 300-space garage at the Property, Tenant shall have the option on a first-come, first- served basis to convert one unassigned parking space per 4,000 square feet of rentable space of the Premises (i.e., up to 18 spaces) to an unassigned space available in the garage for which Tenant shall pay Landlord's prevailing monthly rates. Landlord may, pursuant to Section 6 hereof, establish reasonable rules and regulations regarding Tenant's use of such parking -22- areas. Landlord represents that, as of the date of this Lease, eighteen (18) spaces are available for Tenant's use in said garage. 24. COOPERATIVE INTERRUPTIBLE SERVICE AGREEMENT. Landlord has entered into that certain Cooperative Interruptible Service Agreement dated March 21, 1994 with Massachusetts Electric Company. If Landlord shall be required to pay a penalty or extra fee under such Cooperative Interruptible Service Agreement because of Landlord's election not to allow interruption of electrical service to the Building after request thereof by Massachusetts Electric Company, Tenant shall reimburse Landlord for Tenant's Proportionate Share of the amount of such penalty or extra fee. Such reimbursement shall be made by Tenant to Landlord within thirty (30) days of receipt by Tenant of a statement setting forth the total amount of the penalty or extra fee and Tenant's Proportionate Share thereof. 25. SECURITY DEPOSIT. The security deposit set forth in Item 15 of the Schedule (the "Security Deposit"), shall be deposited and maintained with Landlord as follows: (a) upon full execution hereof Tenant shall deliver a letter of credit in the amount of $500,000, drawable on a national bank headquartered in Boston, Massachusetts and in all other respects acceptable to Landlord (the "LC"); (b) in the event Tenant shall elect to receive any Tenant Improvement Advance from Landlord, Tenant shall, on January 1, 2000, and again, on September 1, 2000 (if additional Tenant Improvement Advances have been made), cause the amount of the LC to be increased to an amount equal to (i) $500,000, plus (ii) the amount of all such Tenant Improvement Advance amounts advanced to Tenant prior to such date, and (c) so long as no Default has occurred under the Lease, Tenant shall be entitled to reduce the amount of the Security Deposit evidenced by the LC by $100,000 per year, beginning on September 1, 2001, and on each anniversary thereof, until the face amount of the LC equals $100,000. In no event shall the amount of the Security Deposit be reduced below $100,000. The Security Deposit is security for the performance of Tenant's obligations under this Lease. Upon the occurrence of a Default, Landlord may use all or any part of the Security Deposit for the payment of any Rent or for the payment of any amount which Landlord may pay or become obligated to pay by reason of such Default, or to compensate Landlord for any loss or damage which Landlord may suffer by reason of such Default. If any portion of the Security Deposit is used, Tenant shall within five (5) days after written demand therefor deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount. Landlord shall not be required to keep the Security Deposit separate from its general funds, and Tenant shall not be entitled to interest on the Security Deposit. In no event shall the Security Deposit be considered an advanced payment of Rent, and in no event shall Tenant be entitled to use the Security Deposit for the payment of Rent. If no default by Tenant exists hereunder, the Security Deposit or any balance thereof shall be returned to Tenant within thirty (30) days after the expiration of the Term and vacation of the Premises by Tenant. Landlord shall have the right to transfer the Security Deposit to any purchaser of the Building. Upon such transfer, Tenant shall look solely to such purchaser for return of the Security Deposit; and Landlord shall be relieved of any liability with respect to the Security Deposit. 26. DIRECTORY; SIGNS. Landlord will place Tenant's i name and suite number on the Building standard directory. Except for signs which are located wholly within the interior of the Premises and which are not visible from the exterior of the Premises, no signs shall be placed, erected, maintained or painted by Tenant at any place upon the Premises or the Property, except with Landlord's prior written approval, which approval shall not be unreasonably withheld or delayed. -23- 27. RENEWAL OPTION A. Provided Tenant is not in default under this Lease beyond applicable cure or grace periods and no event or condition exists which with notice and the expiration of any grace period would constitute a default under this Lease at the time the option may be exercised, and provided Tenant will be occupying all of the Premises on the commencement date of the applicable Renewal Tenn (as hereinafter defined), Landlord grants Tenant one (1) option (the "Renewal Option") to renew this Lease with respect to all of the Premises for one (1) additional period of five (5) years (the "Renewal Term"). The Renewal Option may be exercised by Tenant delivering written notice to Landlord at least twelve (12) months, but no earlier than fifteen (15) months, prior to the expiration date of the Term. Time is of the essence in the exercise of the Renewal Option. B. The Base Rent payable for the Renewal Term shall be one hundred percent (100%) percent of the market rental rate being charged by landlords to tenants renewing their leases in similarly dernised and improved premises in Class A office buildings of similar size and quality, offering a similar amenity package.

Tenant shall have fifteen (15) business days from the receipt of Landlord's notice to either accept or dispute Landlord's determination of the Renewal Rental Rate.

If Landlord and Tenant cannot agree upon the market rental rate within fifty (50) days of Tenant's original notice of its intent to exercise its Renewal Option, the following dispute resolution mechanism shall be utilized: The parties, within ten (10) days after the expiration of said fifty (50) day period, shall jointly appoint as arbitrator, a certified commercial real estate appraiser with a minimum of ten (10) years experience in the applicable market. If Landlord and Tenant cannot agree on an acceptable arbitrator, Landlord and Tenant shall each choose, within an additional ten (10) days thereafter, its own arbitrator who meets the qualifications described above. The arbitrators shall then jointly select, within an additional ten (10) days, an arbitrator to serve as the arbitrator hereunder. Within fifteen (15) days after appointment, the arbitrator shall choose either Landlord's or Tenant's determination of market rental rate. The cost of the arbitrator(s) shall bome equally by Landlord and Tenant. C. Landlord and Tenant shall execute an amendment to this Lease within thirty (30) days after the determination of the market rental rate for the Renewal Term, which amendment shall set forth th& Renewal Term, the annual Base Rent and all other terms and conditions for the Renewal Term.
