Tenant's Space as the same may be expanded pursuant to Exhibit R, with such appurtenances, is hereinafter collectively referred to as "the Premises". 4 8 Tenant shall have, as appurtenant to the Premises, the right to use the areas shown on the Plan attached as Part of hereto as Exhibit A as "Building Parking Area", all subject to and as further provided in Section 10.14 hereof and the Landlord's reserved expansion rights set forth in Exhibit R. Tenant shall also have, as appurtenant to the Premises, the right to use in common with others entitled thereto, subject to reasonable rules of general applicability to tenants and owners of other lots in the park, commonly known and referred to as the Michelson Farm-Westford Technology Park and shown on the Plan of the Park attached hereto as part of Exhibit A (the "Park") from time to time made by Landlord in accordance with Section 6.1.4 of which Tenant is given written notice: (a) the common areas now or hereafter located at the Park (the "Common Areas"), including, without limitation, the Common Areas shown on the Plan of the Park attached hereto as part of Exhibit A, as such Common Areas may be amended or modified by Landlord from time to time during the Term hereof (b) all rights to access, all service areas, drainage of surface water runoff, including, without limitation, storm drainage systems and detention areas, (c) all grades, driveways, roadways, sidewalks and footways, lighting systems and traffic flow patterns, (d) all parking areas designated as common or visitors parking areas for use of the entire Park, if any, (e) all other rights appurtenant to the Lot and the Building, (f) all means of access to and from the Building to the Common Areas, including, without limitation, all sidewalks, roads, driveways and the like, and (g) all utility lines, electricity, water and sewage disposal. The Landlord and the Tenant acknowledge and agree that as a condition of the Tenant's obligations under the Lease, the Tenant shall require a leasehold title insurance policy insuring the Tenant's leasehold interest in the Premises. Inasmuch as the lot plans, easements and related matters are being finalized coterminously with the execution of the Lease, the Landlord covenants with the Tenant that it shall cooperate with the Tenant during the construction of the Premises to finalize a leasehold title insurance policy in form and content reasonably acceptable to the Tenant. A loan policy will be generated by the Landlord in connection with the construction financing to be secured by Landlord and the Tenant's leasehold title policy shall be generated simultaneously therewith. The cost of the Tenant's leasehold title insurance policy shall be the sole responsibility of the Tenant. The Tenant's leasehold title insurance policy shall insure Tenant's right of access to the Premises and all easements required for drainage, utilities and other matters necessary for the Tenant's operations in the Premises. It shall also provide that the improvements to be located on the Lot, including without limitation the parking, shall not interfere with, encroach upon, be prohibited by or cause a violation of any easements which encumber the Lot. 5 9 2.2 TERM To have and to hold for a period (the "Term") commencing on the Term Commencement Date determined in accordance with Section 3.2 (which said date is at times being hereafter referred to as the "Commencement Date") and continuing until the Term Expiration Date, unless sooner terminated as provided in Sections 3.2 or 7.1 or in Article IX, or unless extended pursuant to Exhibit F. ARTICLE III CONSTRUCTION 3.1 INITIAL CONSTRUCTION Landlord shall fully construct the base Building in accordance with the preliminary base building plans, including, without limitation, floor plans, elevations and site plan(s) (collectively, the "PBBP") and Base Building Outline Specifications attached hereto as Exhibits B-1 and B-2, respectively (all of such work being collectively referred to as the "Landlord's Work"). In the event of differences between the PBBP or the Landlord's Plans (as hereinafter defined) and the Base Building Outline Specifications, the Base Building Outline Specifications shall govern and control until the Landlord's Plans (as hereinafter defined) are prepared. A complete set of final base Building plans and construction drawings and specifications, such drawings and specifications to include a detail schedule of core base Building finish items such as, but not limited to, carpets, doors, hardware, ceiling grids/tiles, lavatory fixtures, light fixtures, window blinds, lobby finishes and paint/wall coverings (collectively, the "Landlord's Plans") shall be prepared by Landlord, at its sole cost and expense. Landlord and Tenant agree to work together with Landlord's architect, Symmes Maini and McKee Associates, Inc. in order to achieve a design that meets the standard set forth below. Furthermore, Landlord agrees to use good faith and diligent efforts to deliver the Landlord's Plans to Tenant on or before May 1, 2000. Upon receipt, Tenant shall have seven (7) business days to comment upon the Landlord's Plans. Landlord and Tenant shall use reasonable efforts to reach agreement on the Landlord's Plans as soon thereafter as possible. In reaching agreement, Landlord and Tenant shall each approve portions of the Landlord's Plans that are in acceptable form and shall note their respective objections to the portions that are unacceptable to each of them so as to enable Landlord to continue construction and order materials in a timely manner. In the event that Landlord's Plans conform with the PBBP, but Tenant does not approve the Landlord's Plans within seven (7) business days of receipt thereof from Landlord, then the Outside Delivery Date (as hereinafter defined) shall be extended for a number of days equal to the number of Tenant Plan Delay Days, as such term is hereinafter defined. The number of Tenant Plan Delay Days are defined as and shall be calculated by determining the actual number of days as certified by Landlord and its architect that the Term Commencement Date was delayed by such Tenant's failure to approve the Landlord's Plans within the required seven (7) business days. Landlord agrees to provide Tenant with written notice of such determination, such notice to include reasonable detail describing the cause of the delay and the number of Tenant Plan Delay Days as certified by Landlord and its architect. If Tenant and Tenant's Architect (as hereinafter defined) 6 10 disagree with the existence or calculation of Tenant Plan Delay Days as determined by Landlord and its architect, then Tenant shall, within seven (7) business days of receipt of Landlord's notice, notify Landlord of its disagreement, whereupon the dispute shall be determined pursuant to the arbitration procedures described in Section 3.6 hereof. Landlord and Tenant hereby acknowledge and agree that, except as otherwise set forth herein, following approval by Landlord and Tenant (which shall be in writing as hereinafter provided), no amendments, modifications or changes shall be made to the Landlord's Plans without Tenant's prior written approval in each instance, which such approval shall not be unreasonably withheld or delayed; provided, however, no such prior approval of Tenant shall be required if the proposed amendments, modifications or changes are, in Landlord's reasonable opinion (i) non-material in nature, (ii) replaced by substantially equivalent or better items and at all times equal to or better than that of the building located at 7 Technology Park Drive, Westford, Massachusetts, and (iii) do not adversely affect the Premises. Without limiting the foregoing, Landlord shall exercise reasonable efforts to provide Tenant with prior written notice of all proposed amendments, modifications or changes to the Landlord's Plans. A complete set of construction plans and specifications for Tenant's Work (as hereinafter defined) shall be prepared by Tenant's Architect, as hereinafter defined (collectively, the "Tenant's Plans"). The Tenant's Plans shall be furnished to Landlord as herein provided. Landlord and Tenant hereby acknowledge and agree that Tenant has selected Symmes Maini and McKee Associates, Inc. to be "Tenant's Architect" for preparation of Tenant's Plans, and the costs of services of such Tenant's Architect shall be borne solely by Tenant (other than such portion of the cost to be paid by Landlord pursuant to Exhibit M). Tenant's Architect (and Tenant's Representatives) shall be actively involved in the design decisions and shall be allowed reasonable access to the Lot and the Premises during construction to monitor Landlord's compliance with the terms and provisions of this Lease. Landlord and Tenant hereby further agree that Tenant shall be solely responsible for coordinating with Tenant's Architect for the timely preparation of Tenant's Plans in accordance with the terms and provisions of this Section 3.1. Attached as Exhibit S is a schedule (the "Schedule") setting forth the respective dates by which Landlord and Tenant anticipate that (i) Landlord's Plans shall have been delivered to and approved by Tenant, (ii) Tenant's Plans shall have been delivered to and approved by Landlord, and (iii) certain portions of Landlord's Work and Tenant's Work shall be substantially completed. The parties agree to cooperate with each other and to exercise reasonable efforts to complete the tasks described in the Schedule by the respective dates set forth therein, Landlord and Tenant hereby further agreeing that, unless otherwise expressly set forth herein, failure to meet any of such dates on the Schedule shall not constitute a default or a delay of any type hereunder. Tenant shall deliver the Tenant's Plans to the Landlord by not later than the Scheduled Tenant's Design Completion Date, provided, however, that (i) Tenant furnishes to Landlord by not later than April 14, 2000 all information relating to changes in the structural steel (i.e. rooftop equipment, floor and roof openings, and other equipment exceeding 100 psf live load), and (ii) Tenant furnishes to Landlord by not later than May 1, 2000 all information relating to any added doors at the first floor exterior wall and relating to proposed changes to or additions to the 7 11 elevators and all information relating to any proposed changes or additions to the base building rooftop HVAC equipment and to the electrical service and switchgear. Tenant shall permit Landlord to review and provide input during the preparation of Tenant's Plans. Upon receipt, Landlord shall have five (5) business days to comment upon the Tenant's Plans. Landlord and Tenant shall use reasonable efforts to reach agreement on the Tenant's Plans within ten (10) days of Tenant's receipt of Landlord's comments thereto. In reaching such agreement, Landlord and Tenant shall each approve portions of Tenant's Plans that are acceptable and shall note their respective objections to the portions that are unacceptable to each of them so as to enable Landlord to continue construction and order materials in a timely manner. In connection with Landlord's review of the Tenant's Plans, or if Tenant fails to deliver Tenant's Plans (or any modifications thereto) by the date set forth above, Landlord may require by prompt written notice to Tenant (i) modifications in Tenant's Plans (i.e. if Tenant's Plans are not compatible with Landlord's Plans), and/or (ii) an adjustment in the Outside Delivery Date (such adjustment to be determined by Landlord in its reasonable judgment). Landlord's notice to Tenant shall include reasonable detail describing the cause of the adjustment and/or the extent of the incompatibility with reasonable specificity. Any such extension in time, whether mutually agreed to by Landlord and Tenant or determined by their respective architects in the event of dispute pursuant to Section 3.6, shall result in Tenant's Plan Delay Days as hereinbefore determined. In addition, Landlord will not approve Tenant's Plans which involve any construction, alterations or additions requiring unusual expense to readapt the Premises to normal office use on the Term Expiration Date, unless Tenant first gives assurances acceptable to Landlord that such readaptation shall be made prior to such termination without expense to Landlord. Notwithstanding the preceding sentence, Landlord hereby acknowledges and agrees that such cafeterias, laboratories and other initial Tenant improvements described in Landlord's Plans or Tenant's Plans shall not require removal by Tenant at the expiration of the Term and such initial Tenant improvements shall be allowed to remain without additional cost to Tenant. All revisions and modifications to the Tenant's Plans shall be made promptly by Tenant and revised sets of Tenant's Plans shall be forthwith furnished to Landlord upon Tenant's receipt thereof, Landlord hereby agreeing to inform Tenant during the plan approval process and, in any event, prior to the installation thereof, of any such items that may require unusual expense to readapt the Premises as aforesaid. All revisions and modifications to the Tenant's Plans shall be made promptly by Tenant and revised sets of Tenant's Plans shall be forthwith furnished to Landlord upon Tenant's receipt thereof. Landlord and Tenant hereby further agree to acknowledge in writing when final approval by Landlord and Tenant of Tenant's Plans (and Landlord's Plans) has occurred. No changes or modifications to Tenant's Plans or Tenant's Work being constructed by Landlord pursuant thereto shall be made without Tenant's consent, such consent not to be unreasonably withheld or delayed by Tenant. Landlord shall have fifteen (15) days after final approval of Tenant's Plans and Landlord's receipt of final and complete sets of approved Tenant's Plans, which such final approval has been acknowledged in writing by Landlord and Tenant as aforesaid, to price the cost of Tenant's Work (as hereinafter defined) in accordance with the last paragraph of Section 3.1.1. 8 12 Landlord and Tenant shall cooperate during the above time periods so that each party makes the other aware of their progress with respect to the foregoing plans, selections and pricing, as well as timing, availability or cost constraints of Tenant's selections or specifications and proposed alternates. Landlord shall cause the Premises to be completed in accordance with Landlord's Plans and Tenant's Plans, all of such work to be performed by Landlord's general contractor, Gutierrez Construction Co., Inc. After final approval of Landlord's Plans and Tenant's Plans by Landlord and Tenant, the Tenant may request changes to Landlord's Work or Tenant's Work (as applicable) by altering, adding to, or deducting from Landlord's Work or Tenant's Work (as applicable) as set forth in the agreed form of Landlord's Plans or Tenant's Plans, as applicable (each such requested change is referred to herein as a "Change Order"). A Change Order requested by Tenant in Landlord's Work (or in Tenant's Work as such term is defined in Section 3.1.1 hereof) which affects Landlord's Work may also necessitate an adjustment in the Outside Delivery Date (as defined in Section 3.2 hereof) and may result in Tenant Alteration Delay Days (as hereinafter defined), in accordance with and subject to the terms and conditions set forth below. Landlord shall notify Tenant in writing if such requested Change Order shall result in Tenant Alteration Delay Days, and therefore an adjustment in the Outside Delivery Date. In addition, Landlord agrees to provide Tenant, upon Tenant's request, with sufficient itemization and back-up documentation to facilitate analysis and to confirm the cost of any such changes in the Landlord's Work or the Tenant's Work initiated by Tenant. Tenant shall pay to Landlord an amount equal to the actual cost (as defined in Section 3.1.1 hereof) of Landlord's Work, including the costs of any such changes initiated by Tenant, less any appropriate credits for any Landlord's Work deleted, (hereinafter, the "Net Additional Cost of Landlord's Work"). The Net Additional Cost of Landlord's Work shall be due and payable to Landlord in the manner provided for in Section 3.1.1 hereof. In the event that Tenant requests a Change Order which would, due to materials or equipment having long delivery times or due to resulting sequencing delays, and notwithstanding Landlord's diligent efforts, result in a delay in the Term Commencement Date, then Tenant shall be deemed to have agreed that it will pay Fixed Rent (as hereinafter provided in Section 4.1) and additional rent hereunder for a number of days equal to the actual number of days (the "Tenant Alteration Delay Days") as certified by Landlord and its architect, and agreed to by Tenant and Tenant's Architect as hereinafter provided, by which the Term Commencement Date would be delayed by such alterations or additions, giving due consideration to Landlord's obligation to use diligent efforts to accelerate construction to make up for lost time due to delays. Landlord agrees to promptly provide Tenant with written notice of such determination, such notice to include reasonable detail describing the cause of the delay and the number of Tenant Alteration Delay Days as certified by Landlord and its architect. Should Tenant and Tenant's Architect disagree with the calculation of Tenant Alteration Delay Days as hereinabove determined, then such disagreement shall be resolved pursuant to the provisions of Section 3.6 hereof. All Tenant improvements, changes and additions shall be part of the Premises (and shall remain therein at the end of the Term), except for Tenant's business fixtures, equipment and personal property (which such personal property shall include, without limitation, demountable 9 13 partitions, equipment and telephone or computer systems), all of which fixtures, equipment and personal property shall remain the property of the Tenant and shall be removed at the expiration of the Term; and such other items shall be removed or left as the Landlord and Tenant agree in writing at the time of Landlord's approval of the plans and specifications therefor. Tenant agrees to repair, at its sole cost and expense, any damage to the Premises caused by any such removal by Tenant in accordance with this paragraph. As aforesaid, notwithstanding the foregoing provisions on this paragraph, Tenant shall not be required to remove cafeterias, laboratories or other initial Tenant improvements described in Landlord's Plans or Tenant's Plans upon expiration of the Term and such initial Tenant improvements shall be allowed to remain without additional cost to Tenant. 3.1.1 TENANT'S WORK. Landlord and Tenant agree that Gutierrez Construction Co., Inc. will construct the tenant improvements set forth on the Tenant's Plans (hereinafter "Tenant's Work") with respect to the Premises at cost (as hereinafter defined), plus an amount for general conditions of seven percent (7%) (not to exceed $420,000.00) and a Landlord's contractor's fee of six percent (6%) of such aggregate cost, less an amount equal to the allowance set forth on Exhibit M attached hereto and made a part hereof. In order to provide for payment by Tenant of the cost of Tenant's Work, the Net Additional Cost of Landlord's Work, and any additional costs due to Change Orders provided for hereunder, less said allowance, Tenant expressly covenants with Landlord that Tenant agrees to deposit into an interest-bearing account to be established and maintained by Landlord's mortgagee (or such other escrow agent mutually agreed upon by the parties), (i) by April 1, 2000, $3,000,000.00 (i.e. forty-three percent (43%) of the Total Estimated Cost set forth below), and (ii) by October 1, 2000, an additional $4,000,000.00 (i.e. fifty-seven percent (57%) of the Total Estimated Cost as set forth below). Tenant's deposits into escrow shall be released by Landlord's construction mortgagee, as escrow agent, to Landlord, or its contractors, as the case may be, upon Substantial Completion of Landlord's Work and Tenant's Work, as provided in Section 3.2 hereof. Tenant shall be responsible for payment of escrow fees, if any, incurred by Landlord or Tenant in connection with such escrow account. In addition, Tenant shall be responsible for interest costs and one-half percent (1/2 %) commitment fee incurred by Landlord in connection with its financing of the cost of Tenant's Work and Change Orders, as applicable. Any and all interest earned on the escrowed funds shall be payable to Tenant at such time as the escrow is released by Landlord's mortgagee, or such other mutually agreed upon escrow agent as aforesaid. It is acknowledged and agreed by Landlord and Tenant that Landlord's mortgagee shall have no right to set off such escrow account against any of Landlord's obligations with its mortgagee. In the event that this Lease is terminated by Tenant pursuant to the provisions of Section 3.2, Landlord's mortgagee shall release all amounts in the escrow account (including interest) to Tenant. The total estimated cost to complete the Tenant's Work under this Lease is seven million dollars ($7,000,000.00) or forty dollars ($46.67) per square foot (hereinafter, the "Total Estimated Cost"). To the extent that the actual cost of the Tenant's Work, Net Additional Cost of Landlord's Work and/or Change Orders, as determined by this Article, is greater than the Total Estimated Cost, Landlord shall provide Tenant with written notice of such fact together with 10 14 reasonable supporting information. In such event Landlord shall provide Tenant with monthly construction requisitions for the construction of the portion of the Tenant's Work, Net Additional Cost of Landlord's Work and/or Change Orders in excess of the Total Estimated Cost, and Tenant agrees to deposit into said escrow account monthly the total amount of any such monthly requisitions based on a percentage of completion basis within five (5) business days of receipt thereof, and any such additional deposits made by Tenant shall be released to Landlord at the time and in the manner as the two (2) deposits noted above. Notwithstanding the foregoing, it is hereby acknowledged and agreed that Landlord shall, at Tenant's option, use good faith efforts to obtain third party permanent non-recourse financing for the financing of the foregoing costs due from Tenant hereunder, which shall be subject to the financability of Tenant. If such financing is obtained, Landlord agrees to notify Tenant and to amortize the amount so financed into the Rent due hereunder on such terms to be mutually agreed to by the parties, each acting reasonably and in good faith. Landlord and Tenant hereby further agree (i) to amend this Lease so as to reflect any amount so financed by Landlord hereunder and (ii) the amount so deposited into escrow by Tenant hereunder shall be offset proportionately by the amount financed by Landlord as aforesaid. Landlord and Tenant hereby further acknowledge and agree to enter into a formal escrow agreement with Landlord's mortgagee or such other escrow agent as aforesaid, to implement the foregoing arrangements prior to April 1, 2000, such date being the first date upon which Tenant is required to deposit funds into escrow. A proposed draft of such escrow agreement has been forwarded to Tenant for review and approval. Each requisition shall include copies of all subcontractor's and supplier's applications for payment and satisfactory evidence of payment of all previous invoices submitted by subcontractors and suppliers. In addition, Landlord's architect shall certify that the subject work specified in each of such monthly requisitions has been substantially completed, and a copy of such certification shall accompany each requisition furnished to Tenant hereunder. In no event shall any of such costs due and payable hereunder remain unpaid by Tenant as of the Term Commencement Date. Tenant and Tenant's Architect shall have the opportunity to inspect the subject work and to confirm the foregoing certification by Landlord's architect, and any disputes following such inspection(s) shall be determined pursuant to Section 3.6 hereof. For purposes hereof, Landlord and Tenant further agree that the certification of cost by Gutierrez Construction Co., Inc. shall be based on the definition of cost as more particularly set forth in Exhibit L hereto. Any changes to the Tenant's Plans after the approval of the Tenant's Plans (and any changes to Landlord's Plans after the approval thereof as set forth in Section 3.1 above) shall be in accordance with the form of Work Change Order attached hereto as Exhibit K. If Tenant informs Landlord in writing of its election to require that Landlord bid out the major contracts in the pricing of the cost of Tenant's Work (specifically excluding Landlord's Work hereunder), Landlord agrees to obtain three (3) qualified bids from subcontractors selected from a master list of subcontractors mutually prepared and agreed upon by Landlord and Tenant prior to the soliciting of bids for any item of Tenant's Work exceeding twenty-five thousand 11 15 dollars ($25,000.00). The subcontractor selected for the performance of the work shall be, subject to Tenant's right to select the final bidder as hereinafter provided, the subcontractor with the lowest bid price; provided, however, that if Landlord, in its reasonable judgment, determines that due to changed conditions (such as increased work commitments on the part of the respective subcontractor, or other pertinent factors) the selection of such low bidder could result in Subcontractor Delay Days (as hereinafter defined), then Landlord shall provide written notice (a "Landlord's Subcontractor Notice") thereof to Tenant, which notice shall identify the low bidder and next lowest bidder and indicate the number of Subcontractor Delay Day(s) that would result from selection of the low bidder (giving due consideration of Landlord's obligations to use diligent efforts to accelerate construction to make up for lost time to delays). Tenant shall have four (4) business days upon receipt of such Landlord's Subcontractor Notice to notify Landlord that either (i) Landlord should proceed with the original low bidder (in which event the Outside Delivery Date shall be extended for the number of days (the "Subcontractor Delay Day(s)") equal to the number of Subcontractor Delay Days indicated in Landlord's Subcontractor Notice), or (ii) Landlord's selection of the next lowest bidder is acceptable to Tenant (in which event the Outside Delivery Date shall not be extended), or (iii) Landlord shall select the third bidder if Tenant, in its reasonable discretion, determines that the third bidder should be the one selected for performance of the work (in which event Landlord shall notify Tenant if such selection shall result in Subcontractor Delay Days and if so, the number of delay days, whereupon Tenant shall have an additional four (4) business days to advise Landlord as to its selection). If Tenant so selects such third bidder, then Landlord shall proceed with such bidder and the Outside Delivery Date shall be extended for the number of Subcontractor Delay Days indicated in Landlord's notice. Failure by Tenant to respond within either of said four (4) day periods shall be deemed to constitute acceptance by Tenant of Landlord's selection of the next lowest bidder. Landlord agrees to use reasonable efforts to notify Tenant simultaneously or forthwith upon Tenant's notification to Landlord as to its election set forth in (i), (ii) or (iii) above, if Landlord has knowledge or a reasonable basis to believe that a Subcontractor Delay Day(s) will likely result due to Landlord's notification requirements hereunder, regardless of whether or not Tenant elects to proceed with the original lowest bidder or not. In addition, in the event that Landlord and Tenant are unable to agree on the cost of any portion of said work, any disagreement shall be resolved pursuant to the provisions of Section 3.6 hereof. Upon commencement of the Tenant's Work, Landlord and Tenant hereby further agree, each acting reasonably and in good faith, to attend and participate in weekly construction meetings with Landlord's general contractor's construction manager(s) during such construction process. 3.1.2 TENANT'S CONSTRUCTION WORK. Tenant agrees that any construction included in Tenant's Plans which Tenant specifies to be done by itself or its contractors (hereinafter referred to as "Tenant's Construction Work"), which shall include, for example, Tenant's installation of furnishings, lab equipment, IT/MIS, security and later changes or additions, shall be completed by and coordinated with any work being performed by Landlord in such manner as to maintain harmonious labor relations and not materially damage the Premises or Lot or materially interfere with the operation of the Building 12 16 or with any of Landlord's construction work hereunder, including but not limited to the construction of the Landlord's Work and Tenant's Work. Tenant (including its contractors, agents or employees) shall have access to the Premises and may perform Tenant's Construction Work prior to the Scheduled Term Commencement Date and prior to the commencement of the Term so as to prepare the Premises for occupancy by Tenant ("Pre-Occupancy"), provided that (i) Tenant's contractors, agents or employees work in a harmonious labor relationship with Landlord's general contractor, (ii) reasonable prior written notice is given to Landlord's general contractor specifying the work to be done, and (iii) no work, as reasonably determined by Landlord, shall be done or fixtures or equipment installed by Tenant in such manner as to materially interfere with the completion of Landlord's Work and the Tenant's Work being done by or for Landlord on the Premises. During the period of preoccupancy of the Premises by Tenant in connection with Tenant's Construction Work prior to the commencement of the Term, no Fixed Rent or additional rent or other charges shall accrue or be payable, but otherwise such preoccupancy shall be subject to all the terms, covenants and conditions contained in this Lease. 3.2 PREPARATION OF PREMISES FOR OCCUPANCY. Landlord shall perform the construction work set forth in the Landlord's Plans and the Tenant's Plans, and, therefore, Landlord agrees to use diligent efforts to have the Premises ready for occupancy on the Scheduled Term Commencement Date. Landlord and Tenant agree that time is of the essence, and Landlord agrees to use diligent efforts to accelerate construction to make up for time lost due to any delay. Unless sooner terminated by Tenant pursuant to the provisions of Section 3.2, the Term of this Lease shall commence on the date the Premises are deemed ready for occupancy as set forth below (the "Term Commencement Date"). The Premises shall be deemed "ready for occupancy" on the earlier of: (a) the date on which Tenant occupies all or any portion of the Premises for the Permitted Uses (except this shall not include periods of Pre-Occupancy by Tenant as set forth in Section 3.1.2); or (b) (1) the date on which the construction of all of the Landlord's Work and the Tenant's Work is Substantially Completed, as defined below, and (2) Landlord has delivered to Tenant copies of all permits and approvals (the "Permits") required to be obtained from any governmental agency either in connection with the (i) construction of the Building or the Park, or any part thereof, or (ii) prior to occupancy of the Premises by Tenant, including, without limitation, a permanent certificate of occupancy from the Town of Westford or a temporary certificate of occupancy from the Town of Westford which allows Tenant to use and occupy the Premises, including in all cases use of the elevator(s), and which temporary certificate of occupancy is not conditional on the performance of any work other than the Punch List Work as defined below, except that such Permits shall not be required as a condition of Substantial Completion if Landlord is unable to secure the same due solely to Tenant's failure to complete Tenant's Construction Work as specified in Section 3.1.2 above (which such date, subject to 13 17 additional terms and provisions of this Section 3.2, shall hereinafter be referred to as the date of "Substantial Completion" or which such work shall hereinafter be referred to as "Substantially Completed"). In any event, notwithstanding the achievement of Substantial Completion, all Punch List Work shall be completed by no later than thirty (30) days after the date of Substantial Completion, except as hereinafter provided. An AIA Certificate of Substantial Completion by the Landlord's architect and approved by Tenant's Architect (which such Certificate shall be in the form attached hereto as Exhibit C-1), shall evidence the Landlord's determination that it has performed all such obligations, except for completing the landscaping work and completing the final paving course, and minor items stated in such Certificate to be incomplete or not in conformity with such requirements, or will not materially interfere with Tenant's use or occupancy of the Premises and all of which work shall be identified and specified in the Certificate of Substantial Completion (collectively such landscaping work, finish paving course work and minor items are referred to herein as the "Punch List Work") shall be promptly completed. Tenant shall have the right within fifteen (15) days after Tenant's receipt of said Certificate of Substantial Completion to notify Landlord of its disagreement with said Certificate and to identify additional items of Punch List Work, all of which shall be completed by Landlord within thirty (30) days after notice thereof from Tenant. If weather materially and adversely interferes with Landlord's ability to finish the final course of paving and outside work or such other Punch List Work, which such work does not materially interfere with Tenant's occupancy, and the operation of Tenant's business therein, said work can be completed by Landlord reasonably thereafter, so long as such delay does not and will not interfere with or prevent Landlord from obtaining a certificate of occupancy upon completion of all other work herein described. Notwithstanding the foregoing, in the event that the Punch List Work is not completed by Landlord on or before such date which is six (6) months following the date of Substantial Completion, then Tenant shall have the right, but not the obligation, to complete the Punch List Work and charge the Landlord the difference, if any, between the costs reasonably incurred by Tenant in completing the same, provided that at least thirty (30) days prior written notice has been provided to Landlord, its mortgagee (of whose address Tenant has been given written notice) and The Gutierrez Company (as guarantor under the Guaranty of Completion to be furnished to Tenant upon execution of this Lease, such guaranty to be in the form attached hereto as Exhibit O) and Landlord shall have not cured (or commenced to cure and is not prosecuting curing of the same to completion with due diligence) the same. Landlord agrees to reimburse Tenant pursuant to the provisions of 10.10(b) hereof and shall be entitled to such offset rights as set forth therein. After Landlord has completed all Landlord's Work and Tenant's Work, including all Punch List Work, Landlord's architect shall forward to Tenant its Certificate of Final Completion, such Certificate to be in the form attached hereto as Exhibit C-2. In addition, promptly after completion of all such work, including all Tenant's Construction Work by Tenant, Landlord shall forward to Tenant a final certificate of occupancy from the Town of Westford. 14 18 The phrase "Tenant's Delay" shall mean the aggregate number of days (excluding any days of delay caused by or resulting from Force Majeure) equal to the actual number of days that, notwithstanding its diligent and good faith efforts to complete construction by the Scheduled Term Commencement Date, the Landlord is delayed in completing its construction by the Scheduled Term Commencement Date due to (i) the failure of the Tenant to deliver the Tenant's Plans (or modifications thereto) to Landlord on the dates established pursuant to Section 3.1 hereof, or (ii) a delay caused by Tenant performing the Tenant's Construction Work pursuant to Section 3.1.2 hereof, or (iii) the number of Subcontractor Delay Days pursuant to Section 3.1.1 hereof, or (iv) a delay or stoppage requested in writing by Tenant, or (v) the number of Tenant Alteration Delay Days resulting from Change Orders requested by Tenant pursuant to Section 3.1 hereof, or (vi) the number of Tenant Plan Delay Day(s) pursuant to Section 3.1 hereof, then the Term Commencement Date shall be deemed to have occurred on the date, as certified by Landlord and its architect, and agreed upon by Tenant's Architect, that Substantial Completion would have occurred had there not occurred such Tenant's Delay, calculated by determining the number of days of Tenant's Delay as aforesaid, giving consideration to Landlord's obligation under the second paragraph of this Section 3.2 to accelerate to make up for time lost due to any delays. Landlord agrees to promptly provide Tenant with written notice of such Tenant's Delay promptly after the occurrence of such Tenant's Delay, such notice to include reasonable detail describing the cause of the delay as certified by Landlord's architect. Notwithstanding the foregoing provisions, if the Premises are not deemed ready for occupancy on or before the Outside Delivery Date (as defined below) for whatever reason, Tenant may elect (i) to cancel this Lease at any time thereafter while the Premises are not deemed ready for occupancy by giving notice to Landlord of such cancellation which shall be effective ten (10) days after such notice, unless within such ten (10) day period Landlord delivers the Premises ready for occupancy as defined herein, in which event such notice of cancellation shall be rendered null and void and of no further force or effect, or (ii) to enforce Landlord's covenants to construct the Premises in accordance with the terms of this Lease. In the event Tenant elects to enforce Landlord's agreement to construct the Premises in accordance with this Lease, Tenant shall also have the right to terminate this Lease if Landlord fails to complete the Premises within the period of time set by any court of competent jurisdiction for such work to be completed, or within such additional period of time from the date of Landlord's default as may be mutually agreed to by Landlord and Tenant. Notwithstanding any provisions of this Lease to the contrary, in the event that the Premises are not deemed ready for occupancy on or prior to such date which is ninety (90) days following the Scheduled Term Commencement Date (as such date may be extended for reasons due to Force Majeure and/or to Tenant's Delay), then Tenant may elect to receive from Landlord as liquidated damages an abatement of Fixed Rent, less the Annual Estimated Operating Costs (following commencement of rental obligations pursuant to Section 4.1) equal to one hundred percent (100%) of the Fixed Rent, less the Annual Estimated Operating Costs, for each day the Tenant's Work and Landlord's Work is not Substantially Completed ninety (90) days beyond the Scheduled Term Commencement Date (as such date may be extended as aforesaid). The foregoing remedies shall be Tenant's sole and exclusive remedies for not having the Premises completed on or before the Outside Delivery Date. 15 19 For purposes hereof, the Outside Delivery Date shall be deemed to refer to that certain date which is sixty (60) days following the Scheduled Term Commencement Date, as such date may be extended for a period equal to that of (i) any delays due to Force Majeure as defined in Section 3.5 hereof, (ii) the number of delay days caused by a Tenant's Delay as hereinbefore determined; provided, however, that there shall be no extensions for the matters set forth in clause (i) above (specifically excluding the matters set forth in clause (ii) above) for more than forty-five (45) days in the aggregate. 3.2.1 PARTIAL OCCUPANCY AND RENT COMMENCEMENT. If the entire Premises are not ready for occupancy on the Scheduled Term Commencement Date, the Tenant may elect, but shall have no obligation to, occupy any portion or portions of the Premises which are ready for occupancy when, in Landlord's opinion, it can be done without material interference with remaining work. In such event, Tenant agrees not to materially interfere with Landlord's construction of the Premises. In the event Tenant elects to take occupancy of a portion of the Premises, that portion shall be deemed ready for occupancy as to said portion on the date of occupancy of such portion and Tenant's obligation to pay Fixed Rent and additional rent shall commence on said date pro rata based on the square footage occupied compared to the total square footage in the Premises. The foregoing provisions of this Section 3.2.1 shall not apply to the rights of Tenant set forth in Section 3.1.2 hereof. 3.3 GENERAL PROVISIONS APPLICABLE TO CONSTRUCTION All construction work required or permitted by this Lease, whether by Landlord or by Tenant (or their respective subcontractors), shall be done in a good and workmanlike manner and in compliance with Landlord's Plans and Tenant's Plans and all applicable laws and all lawful ordinances, regulations and orders of governmental authority and insurers of the Building. Either party may inspect the work of the other at reasonable times and shall promptly give notice of observed defects. Notice of said defects shall be in writing and shall be rectified by Landlord or Tenant, as the case may be, within thirty (30) days of the original date of notice. Except as otherwise provided in Section 3.7 hereof, failure to provide notice hereunder shall not be the basis for any liability or for injury or damage caused by such defect of or waiver of right to cause any defect to be corrected. 3.4 REPRESENTATIVES Landlord hereby acknowledges and agrees that only the following persons, Robert T. Curtin, Andrew Currie or Stephen Hassell, or any successors to either of them holding the same title or any other person delegated the authority from either of them in writing (hereinafter "Tenant's Construction Representatives") have the authority to act on Tenant's behalf and represent Tenant's interest with respect to all matters requiring Tenant's action in this Article. No consent, authorization or other action by Tenant with respect to matters set forth in this Article shall bind Tenant unless in writing and signed by one of the aforementioned persons. Landlord hereby expressly recognizes and agrees that no other person claiming to act on behalf of Tenant is authorized to do so. If Landlord complies with any request or direction presented to it by 16 20 anyone claiming to act on behalf of Tenant who does not have the title and position mentioned above, such compliance shall be at Landlord's sole risk and responsibility and shall not in any way alter or diminish the obligations and requirements created and imposed by this Article, and Tenant shall have the right to enforce compliance with this Article without suffering any waiver or abrogation of any of its rights hereunder. Tenant hereby acknowledges and agrees that only the following persons, Arturo J. Gutierrez, John A. Cataldo or P. Agustin Rios or any successors to either of them holding the same title or any other person delegated the authority from either of them in writing (hereinafter "Landlord's Construction Representatives") have the authority to act on Landlord's behalf and represent Landlord's interests with respect to all matters requiring Landlord's action in this Article. No consent, authorization or other action by Landlord with respect to matters set forth in this Article shall bind Landlord unless in writing and signed by one of the aforementioned persons. Tenant hereby expressly recognizes and agrees that no other person claiming to act on behalf of Landlord is authorized to do so. If Tenant complies with any request or direction presented to it by anyone claiming to act on behalf of Landlord who does not have the title and position mentioned above, such compliance shall be at Tenant's sole risk and responsibility and shall not in any way alter or diminish the obligations and requirements created and imposed by this Article, and Landlord shall have the right to enforce compliance with this Article without suffering any waiver or abrogation of any of its rights hereunder. 3.5 FORCE MAJEURE. As used in this Article and elsewhere in the Lease, "Force Majeure" shall mean a time extension equal to that of any delays when the party required to perform the respective obligation is prevented from doing so, despite the exercise of reasonable diligence, and such delay is caused by: (i) Acts of God, (ii) changes in government regulations, (iii) casualty, (iv) strike or other such labor difficulties, (v) unusual weather conditions, (vi) unusual scarcity of or inability to obtain supplies, parts or employees to furnish such services, or (vii) other acts reasonably beyond Landlord's control, but in no event shall the term include economic or financing difficulties. Landlord shall provide Tenant with written notice of the occurrence of a Force Majeure event promptly after the occurrence thereof, and shall comply with its respective obligation(s) as soon as the cause for the delay has (have) been eliminated. As hereinbefore provided in Section 3.2, extensions due to Force Majeure shall be limited to forty-five (45) days in the aggregate. 3.6 ARBITRATION BY ARCHITECTS. Whenever there is a disagreement between the parties with respect to construction by Landlord of Landlord's Work or Tenant's Work, such disagreement shall be definitively determined by the following procedure: Each of Landlord and Tenant shall appoint one (1) independent architect (which such architect may be Landlord's Architect and Tenant's Architect referenced in section 3.1 above), such two (2) architects will then (within five (5) days of their appointment) appoint a third independent architect licensed in the Commonwealth of Massachusetts with not less than ten (10) years experience. Each architect shall establish within ten (10) days of their appointment the matter in dispute. In case of any dispute with respect to 17 21 dollar amounts or lengths of time or dates such as the date of Substantial Completion, the dollar amount or length of time or date shall be the average of the two closest determinations by the three (3) architects, with the determination of the architect which was not closest to another architect's determination excluded from such calculation. In case of any dispute not involving dollar amounts or lengths of time or dates (i.e. the approval of plans) the determination by at least two (2) of the three (3) architects shall be required in order to resolve the matter in dispute. Landlord and Tenant shall each bear the cost of the architect selected by them respectively and shall share equally the cost of the third architect. During such arbitration period, the parties agree to cooperate with one another so as to proceed with construction and with their respective obligations hereunder in a timely manner. Each determination under this Section 3.6 shall be binding upon Landlord and Tenant. 3.7 WARRANTY OF LANDLORD'S WORK AND TENANT'S WORK. Notwithstanding the provisions of Section 3.3, Landlord hereby warrants and guarantees that the Landlord's Work and the Tenant's Work shall be free from defects in workmanship and materials for a period of one (1) year after the Term Commencement Date or such later date upon which all such work has been completed (including Punch List Work). Upon the expiration of said one (1) year period, Landlord shall assign to Tenant any and all warranties and guarantees with respect to Landlord's Work and Tenant's Work and, to the extent that any such warranties and guarantees are not assignable, Landlord agrees to enforce the same for the benefit of Tenant, at Tenant's sole cost and expense. Tenant shall not be responsible to pay for any such warranties of less than one (1) year duration or enforcement by Landlord against its own employees or against Gutierrez Construction Co., Inc. or against any of its other affiliates (including their respective employees). Landlord agrees to repair, at its sole cost and expense any latent defects in Landlord's Work or Tenant's Work promptly after receipt of notice therefrom from Tenant, provided that such notice from Tenant is received by Landlord on or before such date which is three (3) years after the Term Commencement Date or such later date upon which all such work has been completed (including Punch List Work). In connection therewith, Tenant shall notify Landlord promptly after it becomes aware of any such latent defects. Any repairs or replacements or alterations to Landlord's Work or Tenant's Work after said initial one (1) year period, and any work required because of latent defects after said three (3) year period, shall be chargeable to Tenant in accordance with and subject to the provisions of Section 4.2 hereof. ARTICLE IV RENT 4.1 RENT Tenant agrees to pay, without any offset or reduction, except as expressly set forth herein, Fixed Rent equal to 1/12th of the annual Fixed Rent set forth in Section 1.1 in equal installments in advance on the first day of each calendar month included in the Term; and for any portion of a calendar month occurring at the beginning or end of the Term, at the rate payable for such portion in advance. Landlord hereby further agrees to credit the option funds paid by Tenant 18 22 totaling Four Hundred Eighty Five Thousand ($485,000.00) and interest earned thereon (commencing on April 1, 2000) against Tenant's rental obligations due hereunder. 4.2 OPERATING COST ESCALATION With respect to the First Fiscal Year for Tenant's Paying Operating Cost Escalation, or fraction thereof, and any Fiscal Year or fraction thereafter during the Term, Tenant shall pay to Landlord, as additional rent, Operating Cost Escalation (as defined below), if any, on or before the thirtieth day following receipt by Tenant of Landlord's Statement (as defined below). As soon as practicable after the end of each Fiscal Year ending during the Term and after Lease termination, Landlord shall render a statement ("Landlord's Statement") in reasonable detail and according to generally accepted accounting principles, consistently applied, certified by Landlord, and showing for the preceding Fiscal Year or fraction thereof, as the case may be, "Landlord's Operating Costs," EXCLUDING the interest and amortization on mortgages for the Building and Lot or leasehold interests therein and the cost of special services rendered to tenants (including Tenant) for which a special charge is made, BUT INCLUDING, without limitation: real estate taxes on the Building, the Lot and the Common Areas of the Park (including without limitation the sewer treatment plant servicing the Park); installments and interest on assessments for public betterments or public improvements; expenses of any proceedings for abatement of taxes and assessments with respect to any Fiscal Year or fraction of a Fiscal Year; premiums for insurance required to be maintained by Landlord pursuant to this Lease; compensation and all fringe benefits, workmen's compensation, insurance premiums and payroll taxes paid by Landlord to, for or with respect to all persons engaged in the operating, maintaining, or cleaning of the Building and Lot; steam, water, sewer, electric, gas, telephone, and other utility charges not billed directly to tenants by Landlord or the utility, but not including the cost to Landlord of electricity furnished for lighting, electrical facilities, equipment, machinery, fixtures and appliances used by Tenant in Tenant's Space (other than Building heating, ventilating and air conditioning equipment) as set forth in Paragraph VII of Exhibit D; costs of building and cleaning supplies and equipment (including rental); cost of maintenance, cleaning and repairs; cost of snow plowing or removal, or both, and care of landscaping; payments to independent contractors under service contracts for cleaning, operating, managing, maintaining and repairing the Building and Lot (which payments may be to affiliates of Landlord provided the same are at reasonable rates consistent with similar contracts with unaffiliated third parties); the Building's pro rata share (as hereinafter defined) of the cost of operating, maintaining and repairing the Common Areas of the Park (such as, but not limited to, snow plowing, sanding, landscaping, common area and street lighting, security, management and sewer treatment plant maintenance); and all other reasonable and necessary expenses paid in connection with the operation, cleaning, maintenance, and repair of the Building and Lot, or either, and properly chargeable against income, it being agreed that if Landlord installs a new or replacement capital item for the purpose of reducing Landlord's Operating Costs, the costs thereof as reasonably amortized by Landlord over the useful life in years of the capital item so installed in accordance with generally accepted accounting principles ("GAAP"), consistently 19 23 applied, with legal interest on the unamortized amounts, shall be included in Landlord's Operating Costs. Landlord agrees that all of such services to be included in Landlord's Operating Costs shall be obtained by Landlord at commercially reasonable, competitive market rates consistent with the operation and management of comparable "Class A" office buildings in the suburban Boston area. Notwithstanding anything to the contrary contained herein, in no event shall Landlord's Operating Costs include (nor shall Tenant have any obligation to pay any Operating Cost Escalation on account of) the following: (a) Costs, expenses and fees relating to solicitation of, advertising for and entering into leases and other occupancy arrangements for space in the Park, including but not limited to legal fees, space planners' fees, real estate brokers' leasing commissions and advertising expenses. (b) Costs of defending any lawsuits with any mortgagee , costs of selling, syndicating, financing, mortgaging or hypothecating any of Landlord's interest in the Park (or any part thereof), costs of any disputes between Landlord and its employees, disputes of Landlord with building management, or outside fees paid in connection with disputes with other tenants or adjacent property owners. (c) Costs of correcting defects in the Building or the Building equipment or replacing defective equipment at any time during the three (3) year period described in Section 3.7, subject to the provisions of said Section 3.7, and thereafter solely to the extent such costs relate to items covered by warranties of manufacturers, suppliers or contractors or are otherwise borne by parties other than Landlord and for which Landlord receives reimbursement. (d) Costs of installations or improvements of any type paid by or constructed for specific tenants or other occupants. (e) Interest, points, other finance charges and principal payments on mortgages, and other costs of indebtedness, if any. (f) All amounts which are specifically charged to or otherwise paid by any other tenant or other occupant of the Building or the Park, or for items or services which Landlord provides selectively to one or more tenants (other than Tenant) without reimbursement. (g) Any bad debt loss, rent loss or reserves for bad debts or rent loss. (h) The salary and indirect compensation (including, without limitation, all fringe benefits, workmen's compensation, insurance premiums and payroll taxes) of any employee above the trade of building manager, and the wages and indirect 20 24 compensation of any employee to the extent such employee devotes his or her time to property other than the Building. (i) Amounts, if any, paid as ground rental by Landlord. (j) Expenses related to landlord-tenant disputes. (k) Management fees in excess of five percent (5%) of gross collected rents. (l) Costs related to hazardous material clean-up, remediation and other expenses (unless due to Tenant's actions), Landlord and Tenant hereby agreeing that in no way shall this exclusion limit or impair Tenant's obligations set forth in Section 6.1.17 hereof. (m) Costs of capital improvements, except for such capital improvements specifically provided for in this Section 4.2. Notwithstanding any language to the contrary contained herein, Landlord's Operating Costs shall be reduced by reimbursements, credits, discounts, reductions or other allowances received or receivable by Landlord for items of cost included in Landlord's Operating Costs (except for reimbursements to Landlord by tenants under the additional rent provisions of their respective leases), including any tax refunds realized as a result of any abatement proceeding or otherwise. Tenant shall be responsible to pay its share of Operating Cost Escalation (as defined below) for the Building based upon the proportion that the Rentable Floor Area of Tenant's Space bears to the Total Rentable Floor Area of the Building as the same may be expanded pursuant to the terms of Exhibit R hereto. Landlord and Tenant hereby acknowledge and agree that the Building's pro rata share of Park-related costs shall be allocated by Landlord in a commercially reasonable manner based upon the following: upon the ratio of the square footage of the Premises to the aggregate square footage of all completed buildings in the Park, as such buildings are completed from time to time, and, with respect to sewer treatment plant expenses, connected for service from time to time to the sewer treatment plant, and upon factors such as usage of a particular tenant in the Park and/or such other pertinent factors as reasonably determined by Landlord. "Operating Cost Escalation" shall be equal to the difference, if any, between: (a) the product of Landlord's Operating Costs per rentable square foot as indicated in Landlord's Statement times the Rentable Floor Area of Tenant's Space; and (b) the product of the Annual Estimated Operating Costs per rentable square foot times the Rentable Floor Area of Tenant's Space. 21 25 If, with respect to any Fiscal Year or fraction thereof during the Term, Tenant is obligated to pay Operating Cost Escalation, then Tenant shall pay, as additional rent, on the first day of each month of each ensuing Fiscal Year thereafter, until Landlord's Statement for an ensuing Fiscal Year reflects that Tenant is not obligated to pay Operating Cost Escalation, Estimated Monthly Escalation Payments equal to 1/12th of the annualized Operating Cost Escalation for the immediately preceding Fiscal Year, Estimated Monthly Escalation Payments for each ensuing Fiscal Year shall be made retroactively from the first day of such Fiscal Year and on account of the payment to be made pursuant to the first sentence of this Section 4.2 for such Fiscal Year, with an appropriate additional payment or refund to be made at the time such payment is due. The term "Fiscal Year" as used in this Article shall mean the period of twelve (12) consecutive months commencing on January 1 and ending on December 31. The term "real estate taxes" as used above shall mean all ad valorem real estate taxes assessed by any governmental authority on the Lot, the Building and improvements, or both, and the Common Areas of the Park, subject to the following: There shall be excluded from such taxes (i) any governmental or business park "special assessments" (i.e. roads and sewers) not considered to be "property" taxes hereunder, and (ii) all income taxes, excess profits taxes, excise taxes, franchise taxes, estate, succession, inheritance and transfer taxes, provided, however, that if at any time during the Term the present system of ad valorem taxation of real property shall be changed so that in lieu of the whole or any part of the ad valorem tax on real property, there shall be assessed on Landlord a capital levy or other tax on the gross rents received with respect to the Lot, Building and improvements, or both, and the Common Areas of the Park, a federal, state, county, municipal, or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect) measured by or based, in whole or primarily, upon any such gross rents, then any and all of such taxes, assessments, levies or charges, to the extent so measured or based, shall be deemed to be included within the term "real estate taxes". If the total of the monthly payments paid by Tenant with respect to any Fiscal Year exceeds the actual Operating Cost Escalation for such Fiscal Year, then, at Landlord's option, such excess shall be either (i) credited against payments on account of Operating Cost Escalation next due hereunder, or (ii) refunded by Landlord to Tenant. The amount of any refund of real estate taxes shall be credited against real estate taxes for the Fiscal Year in which such refund is received; provided, however, in the event that Landlord receives a refund on account of real estate taxes after the expiration of the Term, which refund relates to a Fiscal Year during the Term, the amount of such refund fairly allocable to Tenant shall be refunded to Tenant by Landlord. All references to real estate taxes "for" a particular Fiscal Year shall be deemed to refer to real estate taxes due and payable during such Fiscal Year without regard to when such impositions are assessed or levied. All records that the Landlord is required to maintain hereunder shall be maintained by the Landlord for a period of two (2) years following the expiration of the Fiscal Year to which such records relate. Tenant shall have the right, through its representatives, but not an obligation, to examine, copy and audit such records at reasonable times, but no more than once per Fiscal Year, 22 26 upon not less than thirty (30) days prior written notice. Such records shall be maintained at Landlord's Address set forth in Section 1.1, or such other place within the Commonwealth of Massachusetts as Landlord shall designate from time to time for the keeping of such records. The costs of such audits shall be borne by Tenant; provided, however, that if such audit establishes that the actual Operating Cost Escalation for the Fiscal Year in question is less than the Landlord's final determination of the Operating Cost Escalation as set forth in the Landlord's Statement submitted to Tenant by at least ten (10%) percent, then Landlord shall pay the reasonable cost of such audit. If, as a result of such audit, it is determined that Tenant must pay additional amounts to Landlord on account of the Operating Cost Escalation, or that Tenant has overpaid Landlord on account of the Operating Cost Escalation, then the undercharged or overpaid party shall reimburse the other party for the payment due, together with interest thereon from the date of Landlord's Statement at the interest rate set forth in Section 4.3 hereof. In no event shall the provisions of this paragraph require Tenant to complete any such audit. Notwithstanding anything contained to the contrary in this Lease, the initial responsibility for the payment of all real estate taxes with respect to the Building and the Park shall be upon the Landlord and the Landlord agrees to pay the same as required by law. Landlord shall provide Tenant with a computation of Tenant's pro rata share thereof, and upon Tenant's request, copies of all tax bills. Landlord shall have the right from time to time to change the periods of accounting under this Section 4.2 to any annual period other than the Fiscal Year and upon any such change all items referred to in this Section shall be appropriately apportioned. In all Landlord's Statements, rendered under this Section, amounts for periods partially within and partially without the accounting periods shall be appropriately apportioned, and any items which are not determinable at the time of a Landlord's Statement shall be included therein on the basis of Landlord's estimate, and with respect thereto Landlord shall render promptly after determination a supplemental Landlord's Statement, and appropriate adjustment shall be made according thereto.

In no event shall Landlord be obligated to indemnify Tenant for any willful or negligent act or omission of Tenant or of any of Tenant's employees, agents, contractors or licensees; 5.1.8 Hazardous Materials - Landlord represents and warrants that, to the best of Landlord's knowledge as of the date of this Lease and as of the date of Substantial Completion (i) there does not exist (and will not exist as of the date of Substantial Completion) any leak, spill, release, discharge, emissions or disposal of Hazardous Materials on the Lot (including the Building to be located thereon), and (ii) the Premises do not (and will not as of the date of Substantial Completion) contain any Hazardous Materials, except as may be contained in customary cleaning supplies or in such other supplies (e.g. paint) that are necessary for Landlord to perform its obligations hereunder. In the event that any such leak, spill, release, discharge, emission or disposal of Hazardous Materials shall occur on the Lot or (apart from DE MINIMIS amounts of such materials used for cleaning and maintenance purposes or in connection with the operation of loading docks) the Park not caused by Tenant or its officers, employees, agents, contractors or licensees, Landlord shall take any and all actions necessary to bring the Premises, the Park and/or the Building (excluding all portions thereof leased or leasable to tenants) into compliance with applicable law and other governmental requirements relating thereto. Landlord agrees to notify Tenant immediately upon discovery of any Hazardous Materials on the Premises or in the Park and to indemnify, defend and hold harmless Tenant and its officers, employees and agents from and against any claims, judgments, damages, penalties, fines, costs, liabilities or loss (including without limitation reasonable attorneys' fees) which arise during or after the date hereof from or in connection with the presence or suspected presence of Hazardous Materials on the Premises or in the Park caused directly by the negligent acts or willful misconduct of Landlord. Notwithstanding any language to the contrary set forth in this Lease, in no event shall Landlord be obligated to indemnify Tenant for any Hazardous Materials which arise, as a result of the negligent acts or willful misconduct of Tenant, its officers, employees, agents, contractors or licensees. The covenants and indemnifications set forth in this Section 5.1.8 shall survive the expiration or earlier termination of this Lease; and 5.1.9 Tenant's Costs - In case Tenant shall, without any fault on its part, be made party to any litigation commenced by or against Landlord or by or against any parties in possession of the Premises or any part thereof claiming under Landlord, Landlord agrees to reimburse Tenant for all reasonable costs, including without implied limitation, reasonable counsel fees, incurred by or imposed upon Tenant in connection with such litigation and to pay all such reasonable costs and fees incurred in connection with the successful enforcement by Tenant of any obligations of Landlord under this Lease. 26 30 Except as specifically provided to the contrary in Section 4.2, Landlord shall charge Tenant under the provisions of Section 4.2 for the costs incurred by Landlord in connection with the services and/or repairs set forth in Sections 5.1.1, 5.1.2, 5.1.3 and 5.1.6 above; provided, however, Landlord shall be responsible to pay the following, at its sole cost and expense: (i) repairs or replacements which are necessary to maintain the structural integrity of the Building and the roof during the Term of this Lease (expressly including any renewal terms hereunder), and (ii) maintenance and repairs (and replacements, if necessary) during the initial one (1) year period (or three (3) year period as to latent defects) described in Section 3.7 or otherwise covered by Landlord's or manufacturers warranties described in Section 3.7 above. 5.2 INTERRUPTIONS Except as otherwise set forth below in this Section 5.2, Landlord shall not be liable to Tenant for any compensation or reduction of rent by reason of inconvenience or annoyance or for loss of business arising from power losses or shortages or from the necessity of Landlord's entering the Premises for any of the purposes in this Lease authorized, or for repairing the Premises or any portion of the Building or Lot. In case, notwithstanding Landlord's diligent efforts in connection therewith (which such efforts shall never obligate Landlord to pay for overtime and/or premium time work, or to pay a premium for expedited delivery, except as such additional costs are so authorized and paid for by Tenant), Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any service or performing any other covenant or duty to be performed on Landlord's part, by reason of any cause reasonably beyond Landlord's control (expressly excluding Landlord's financial inability), Landlord shall not be liable to Tenant therefore, nor, except as expressly otherwise provided in Article III or Article VII, shall Tenant be entitled to any abatement or reduction of rent by reason thereof, nor shall the same give rise to a claim in Tenant's favor that such failure constitutes, actual or constructive, total or partial, eviction from the Premises. Landlord reserves the right to stop any service or utility system when necessary by reason of accident or emergency or until necessary repairs have been completed. Except in case of emergency repairs, Landlord will give Tenant reasonable advance notice of any contemplated stoppage and will use reasonable efforts to avoid unnecessary inconvenience to Tenant by reason thereof. Notwithstanding any language to the contrary, if, due solely to any act or omission on the part of Landlord, electricity, heat, air conditioning, water or any other service or utility that Tenant is entitled to receive under this Lease is interrupted, and such interruption renders the Premises untenantable, or any portion thereof is reasonably inaccessible by Tenant, or makes it impracticable for Tenant to conduct its business in the Premises, then if such interruption or cessation shall continue for a period of thirty (30) consecutive days after notice thereof from Tenant to Landlord that the Premises are untenantable, or reasonably inaccessible, or Tenant cannot conduct its business as a result thereof, then the Fixed Rent and additional rent shall be proportionately abated for each successive day such interruption or cessation continues based upon that certain portion of the Premises that are affected by such interruption (other than for 27 31 reasons of casualty or eminent domain where the provisions of Article VII shall govern). In addition, in the event that any such interruption or cessation shall continue for more than ninety (90) successive days, after notice thereof from Tenant to Landlord that the Premises are untenantable, or reasonably inaccessible, or Tenant cannot conduct its business as a result thereof, then Tenant shall have the right to cancel this Lease by giving written notice to Landlord and its mortgagee(s) (of which Tenant has received written notice) of such cancellation, provided that at least ten (10) days prior written notice to Landlord and thirty (30) days prior written notice to Landlord's mortgagee has been given (which such notice may be given prior to or after the expiration of said ninety (90) day period), unless within such ten (10) day period Landlord repairs or restores such interruption as herein required, in which event such notice of cancellation from Tenant shall be rendered null and void and of no further force or effect. For purposes of this Section, Landlord and Tenant hereby acknowledge and agree that if the Premises (or portion thereof) is rendered inaccessible by elevator, but accessible by stairway(s), then the Premises (or such portion) will not be deemed "reasonably inaccessible" for the purposes hereof. Notwithstanding anything to the contrary contained in this Section 5.2, in no event shall Tenant be entitled to any such abatement or reduction of rent or to any such right of termination if such interruption resulting in the Premises being untenantable or unfit for Tenant's business operations therein is due to an event of default by Tenant as set forth in Section 9.1 hereof or is not due to any act or omission on the part of Landlord. Except as set forth in this Section 5.2 or in Article VII, the foregoing rights shall be Tenant's sole remedy at law or in equity for any interruptions described in this Section 5.2. ARTICLE VI TENANT'S COVENANTS 6.1 TENANT'S COVENANTS DURING THE TERM Tenant covenants during the Term: 6.1.1 Tenant's Payments - To pay when due (a) all Fixed Rent and additional rent, (b) all taxes which may be imposed on Tenant's personal property in the Premises (including, without limitation, Tenant's fixtures and equipment) (c) directly to the utility provider (if not payable to Landlord), subject however, to Tenant's right to contest and seek abatement thereof, all charges by public utility for telephone and other utility services (including service inspections therefor and the charges as may be imposed pursuant to Exhibit D hereof including all electric and gas consumed on the Premises) rendered to the Premises not otherwise required hereunder to be furnished by Landlord without charge and not consumed in connection with any services required to be furnished by Landlord without charge, and (d) as additional rent, all reasonable charges of Landlord for services rendered pursuant to Section 5.1.1, 5.1.2, 5.1.3, and 5.1.6 hereof, except as set forth in the last paragraph of Section 5.1. 28 32 6.1.2 Repairs and Yielding Up - Except as otherwise provided in Article VII and Section 5.1.3, to keep the interior, non-structural and non-building system elements of the Premises in good order, repair and condition, reasonable wear and damage or destruction by casualty or eminent domain excepted, and at the expiration or termination of this Lease peaceably to yield up the Premises and all changes and additions therein in such order, repair and condition, first removing all goods and effects of Tenant and any items, the removal of which is required by agreement or specified therein to be removed at Tenant's election and which Tenant elects to remove, Landlord and Tenant hereby acknowledging and agreeing, however, that the initial improvements constructed by Landlord pursuant to Article III and described in Landlord's Plans and Tenant's Plans referenced therein (including without limitation any cafeteria(s) and laboratories) shall not be required to be removed by Tenant upon expiration of the Term, as hereinbefore provided in Section 3.1, and repairing all damage caused by such removal and leaving them clean and neat; any property not so removed shall be deemed abandoned and may be removed and disposed of by Landlord, in such manner as Landlord shall determine, and Tenant shall pay Landlord the entire reasonable cost and expense incurred by it by effecting such removal and disposition; 6.1.3 Occupancy and Use - To use and occupy the Premises only for the Permitted Uses; and not to injure or deface the Premises, Building or Lot; and not to permit in the Premises any auction sale, nuisance, or the emission from the Premises of any objectionable noise or odor, nor to permit any use thereof which is improper, offensive, contrary to law or ordinances, or liable to invalidate or increase the premiums for any insurance on the Building or its contents or liable to render necessary any alteration or addition to the Building, unless Tenant agrees to pay such increased premiums and/or costs, and such use (if other than Permitted Uses) is approved by Landlord in advance; 6.1.4 Rules and Regulations - To comply with the Rules and Regulations set forth in Exhibit E and all other reasonable Rules and Regulations hereafter made by Landlord, of which Tenant has been given notice, for the care and use of the Building, Lot and Common Areas of the Park (and their facilities and approaches as further described in the Park Covenants attached hereto as Exhibit I), it being understood that Landlord shall not be liable to Tenant for the failure of other tenants of the Building or Park to conform to such Rules and Regulations; provided that (i) such Rules and Regulations are enforced in a non-discriminatory fashion, (ii) such Rules and Regulations do not materially interfere with or otherwise diminish Tenant's use of the Premises and the Building Parking Area or Tenant's rights under this Lease, (iii) result in no additional cost or expense to Tenant, and (iv) do not impose any additional obligation on Tenant. 6.1.5 Compliance with Laws and Safety Appliances - To keep, from and after the initial installation thereof by Landlord, subject to the provisions of Section 10.18 (c), the 29 33 Premises equipped with all safety appliances required by law or ordinance or any other regulation of any and public authority because of any particular manner of use made by Tenant and to procure and comply with all licenses and permits so required because of such use, it being understood that the foregoing provisions shall not be construed to broaden in any way Tenant's Permitted Uses. Tenant shall have the right, upon giving notice to the Landlord, to contest any obligation imposed upon it pursuant to the provisions of this Section 6.1.5, and provided the enforcement of such requirement or law is stayed during such contest and such contest will not subject the Landlord to penalty or jeopardize the title to the Premises or otherwise affect the Premises in any adverse way. Landlord shall cooperate with Tenant in such contest and shall execute any documents reasonably required in the furtherance of such purpose. Notwithstanding the foregoing or any other provision of this Lease, however, Tenant shall not be responsible for compliance with any such laws, regulations, or the like requiring (i) structural repairs or modifications or (ii) repairs or modifications to the utility or building service equipment located outside of and not exclusively serving the Premises or (iii) installation of new building service equipment, such as fire detection or suppression equipment, unless such repairs, modifications, or installations shall (a) be due to Tenant's Construction Work, alterations, or repairs in the Premises or Tenant's particular manner of use of the Premises (as opposed to commercial office operations, generally), or (b) be due to the negligence or willful misconduct of Tenant's or any agent, employee, or contractor of Tenant. 6.1.6 Assignment and Subletting -Tenant shall have the right, subject to the requirement of obtaining Landlord's prior written consent, such consent not to be unreasonably withheld or delayed by Landlord, to assign this Lease or sublet the whole or any portion of the Premises, which assignment or sublease shall be only for the Permitted Uses, it being understood that Tenant shall, as additional rent, reimburse Landlord promptly for reasonable legal and other expenses incurred by Landlord in connection with any request by Tenant for consent to assignment or subletting. No assignment or subletting shall affect the continuing primary liability of Tenant (which, following assignment, shall be joint and several with the assignee). Such consent by Landlord to any of the foregoing in a specific instance (i) shall be reasonable, subject to the provisions hereinafter provided, and (ii) shall be subject to the prior written approval of Landlord's mortgagee(s). Landlord's consent shall not be treated as having been withheld unreasonably if, in connection with any such proposed assignment or subletting: (i) the terms of the proposed assignment or subletting do not prohibit further assignments of the Lease or subletting of the Premises without the written consent of Landlord, the granting of which consent shall be subject to the terms and conditions hereof, and in any event shall not be unreasonably withheld or delayed; and/or (ii) in connection with an assignment of this Lease, the assignee does not agree directly with Landlord, by written instrument in form reasonably satisfactory to Landlord, to be bound by all the obligations of Tenant hereunder including, without limitation, the covenant against further assignment and subletting without the 30 34 written consent of Landlord; and/or (iii) the proposed assignment or subletting violates any exclusive use restrictions or exclusions of the Building or Park as set forth in Exhibit Q. Tenant hereby acknowledges and agrees that the foregoing is not intended to be an exclusive list of the reasons for which Landlord may reasonably withhold consent to a proposed request by Tenant for consent to assignment or subletting. No consent to any of the foregoing in a specific instance shall operate as waiver in any subsequent instance. If an assignment or subletting is proposed to be made and Landlord's consent is required as hereinabove provided, Tenant shall give Landlord prior notice of such proposal, which such notice shall include such information as Landlord may reasonably request relative to facts which would bear upon the factors entering into the determination whether Landlord's approval is to be granted, and it is understood that Landlord shall use diligent efforts within a period of thirty (30) days after the submission of such information by Tenant to make its determination whether Landlord's approval is to be granted hereunder. If Tenant requests Landlord's consent to assign this Lease or sublet more than sixty percent (60%) of the Premises, Landlord shall have the option, exercisable by written notice to Tenant given within thirty (30) days after receipt of such request, to recapture the portion of the Premises proposed to be assigned or sublet as of a date specified in such notice which shall be not less than forty-five (45), or more than sixty (60) days after the date of such notice, in such event the recaptured area of the Premises shall be removed from the Premises and Tenant shall have no further liabilities or obligations with respect thereto, including obligations to pay Fixed Rent, additional rent or other charges with respect thereto; and any rental received by Tenant from sub-tenant must be remitted to Landlord; provided, however, upon Tenant's receipt of any such written notice from Landlord exercising its right of recapture hereunder, Tenant shall have the option, exercisable by written notice to Landlord given within ten (10) days after receipt of such Landlord's notice, to withdraw its request to assign or sublet all or a portion of the Premises, whereupon Landlord's notice to Tenant exercising its right of recapture hereunder shall become null and void and of no force or effect as to Tenant's particular request for Landlord's consent hereunder. Notwithstanding any provision contained in this Lease, no consent of Landlord shall be required for the assignment of this Lease or the subletting of any portion (or the whole) of the Premises for the Permitted Uses, (i) to a subsidiary of Tenant, (ii) to a corporation or other entity into or with which Tenant has merged or consolidated or to which substantially all of Tenant's stock or assets are transferred, (iii) to any corporation or other entity which controls, is controlled by, or is under common control with Tenant, or (iv) to any corporation or other entity with which Tenant is otherwise affiliated (collectively, the "Permitted Transferees"); provided that, in any of such events, Tenant shall remain directly and primarily liable and any such sublessee or assignee agrees directly with Landlord by written instrument reasonably satisfactory to Landlord and such 31 35 assignee or sublessee to be bound by all of the obligations of Tenant. In the event of any such assignment or subletting for which no consent by Landlord is required hereunder, Tenant shall not be obligated to share Rent Differential as hereinafter set forth, nor shall the recapture rights of Landlord set forth in the preceding paragraph be applicable. If this Lease shall be assigned, or if the Premises or any part hereof shall be sublet or occupied by any person other than Tenant, Landlord may, at any time and from time to time, collect rent from the assignee, subtenant or occupant and apply the net amount collected to the annual Fixed Rent, additional rent and all other charges herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of the provisions of this Section 6.1.6, or acceptance of the assignee, subtenant or occupant as tenant, or a release of Tenant from the further performance of the terms, covenants and conditions of this Lease on the part of Tenant to be performed. Further, no liability hereunder of Tenant shall be discharged, reduced, released or impaired in any respect by any waiver, indulgence or extension of time which Landlord may grant to the then owner of Tenant's interest in this Lease, whether or not notice thereof has been given or consent from Tenant has been obtained. Landlord shall have the option to require that any portion of rental received by Tenant from subtenant or assignee to which Landlord is entitled pursuant to this Section 6.1.6 be remitted directly to Landlord, provided that such amounts are credited pro tanto against Tenant's rental obligations. If Landlord approves a sublease or assignment, and said sublease or assignment is for a total rental amount which on an annualized basis is greater than the Fixed Rent and additional rent due from Tenant to Landlord under this Lease, Tenant shall pay to Landlord, forthwith upon Tenant's receipt of each installment of such excess rent, during the term of any approved sublease or assignment, as additional rent hereunder, in addition to the Fixed Rent and other payments due under this Lease, an amount equal to fifty percent (50%) of the positive excess between all fixed rent and additional rent received by Tenant under the sublease or assignment and the Fixed Rent and the additional rent due hereunder after Tenant has recouped its reasonable out-of-pocket expenses with respect to such sublease or assignment, including without limitation, reasonable real estate brokerage commissions, reasonable legal fees, reasonable free rent, reasonable marketing costs and the reasonable costs of refurbishment of the Premises for such sublease or assignment (the "Rent Differential"). In the event the sublease is for less than the full Premises hereunder, the above rent adjustment shall be equitably pro rated on a square foot basis. Anything contained in the foregoing provisions of this section to the contrary notwithstanding, neither Tenant nor any other person having interest in the possession, use, occupancy or utilization of the Premises shall enter into any lease, sublease, license, concession or other agreement for use, occupancy or utilization of space in the Premises which provides for rental or 32 36 other payment for such use, occupancy or utilization based, in whole or primarily on the net income or profits derived by any person from the Premises leased, used, occupied or utilized (other than an amount based on a fixed percentage or percentages of receipts or sales), and any such purported lease, sublease, license, concession or other agreement shall be absolutely void and ineffective as a conveyance of any right or interest in the possession use, occupancy or utilization of any part of the Premises; 6.1.7 Indemnity - To defend, with counsel reasonably acceptable to Landlord, save harmless, and indemnify Landlord from any liability for injury, loss, accident or damage to any person or property occurring on the Premises, in the Building, or elsewhere in the Park, and from any claims, actions, proceedings and expenses and costs in connection therewith or elsewhere in the Park (including, without implied limitation, reasonable counsel fees): (i) arising from the negligent acts or gross misconduct of Tenant or any of Tenant's employees, agents, contractors, licensees or invitees and not caused directly by the negligent acts or gross misconduct of Landlord, or (ii) resulting from the failure of Tenant to perform and discharge its covenants and obligations under this Lease. In no event shall Tenant be obligated to indemnify Landlord for any willful or negligent act or omission of Landlord or any of Landlord's employees, agents, contractors or licensees. The covenants and indemnifications set forth in this Section 6.1.7 shall survive the expiration or earlier termination of this Lease; 6.1.8 Tenant's Liability Insurance - To maintain public liability insurance in the Premises in amounts which shall, at the beginning of the Term, be at least equal to the limits set forth in Section 1.1 and from time to time during the Term, shall be for such higher limits, if any, as are customarily carried in the area in which the Premises are located on property similar to the Premises and used for similar purposes and, upon written request therefor, to furnish Landlord (and/or its mortgagees) with certificates thereof; 6.1.9 Tenant's Workmen's Compensation Insurance - To keep all Tenant's employees working in the Premises covered by workmen's compensation insurance in statutory amounts and to furnish Landlord with certificates thereof; 6.1.10 Landlord's Right of Entry - Upon not less than twenty-four (24) hours advance notice (except in the event of emergencies), at times reasonably acceptable to Landlord and Tenant, to permit Landlord and Landlord's agents entry; to examine the Premises at reasonable times and, if Landlord shall so elect, to make repairs or replacements; to remove, at Tenant's expense, any changes, additions, signs, curtains, blinds, shades, awnings, aerials, flagpoles, or other improvements visible outside the Building not consented to in writing by Landlord (Landlord hereby acknowledging that the initial improvements constructed by Landlord pursuant to Article III shall be permitted and may remain upon expiration of the Term as hereinbefore provided in Sections 3.1 and 6.1.2); and to show the Premises to 33 37 prospective tenants during the twelve (12) months preceding expiration of the Term and to prospective purchasers and mortgagees at all reasonable times; 6.1.11 Loading - Not to place a load upon the Premises exceeding an average rate of one hundred (100) pounds of live load per square foot of floor area; and not to move any safe, vault or other heavy equipment in, about or out of the Premises except in such a manner and at such times as Landlord shall in each instance approve; Tenant's business machines and mechanical equipment which cause vibration or noise that may be transmitted to the Building structure shall be placed and maintained by Tenant in settings of cork, rubber, spring, or other types of vibration eliminators sufficient to eliminate such vibration or noise; 6.1.12 Landlord's Costs - In case Landlord shall, without any fault on its part, be made party to any litigation commenced by or against Tenant or by any party claiming under Tenant, to pay, as additional rent, all actual third party reasonable costs including, without implied limitation, reasonable counsel fees incurred by or imposed upon Landlord in connection with such litigation, and, as additional rent, also to pay all such reasonable costs and fees incurred by Landlord in connection with the successful enforcement by Landlord of any obligations of Tenant under this Lease; 6.1.13 Tenant's Property - All the furnishings, fixtures, equipment, effects and property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant which, during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming under Tenant, may be on the Premises or on the Lot shall be at the sole risk and hazard of Tenant, except for Landlord's gross negligence or willful act or omission, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft, or from any other cause, no part of said loss or damage is to be charged to or to be borne by Landlord, except if caused directly by Landlord's gross negligence or willful misconduct; 6.1.14 Labor or Materialmen's Liens - To pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees, or independent contractors; not to cause or permit any liens for labor or material performed or furnished in connection therewith to attach to the Premises; and within ten (10) days after Tenant's receipt of notice thereof, to discharge or bond over any such liens which may so attach; 6.1.15 Changes or Additions - Not to make any material changes or additions to the Premises without Landlord's prior written consent, which such consent shall not be unreasonably withheld or delayed. Notwithstanding the foregoing, Tenant may, from time to time, at its own cost and expense and without the consent of Landlord, make non-structural alterations, additions or improvements to the 34 38 Premises, so long as they do not affect any of the mechanical, electrical or plumbing systems of the Building (collectively herein called "Alterations") whose cost in any one instance is Twenty-Five Thousand Dollars ($25,000.00) or less, provided that Tenant first notifies Landlord in writing of any such Alterations. If Tenant desires to make any Alterations costing in excess of Twenty-Five Thousand Dollars ($25,000.00) in any one instance or any other alteration, including any structural alteration or alteration affecting any of the mechanical, electrical or plumbing systems of the Building, Tenant must first obtain the consent of Landlord thereto, which consent shall not be unreasonably withheld or delayed. If Landlord reasonably concludes that the Alterations involve any construction, alterations or additions requiring unusual expense to readapt the Premises to normal office use on the Term Expiration Date, Landlord shall notify Tenant in writing at the time of approval that such readaptation will be required to be made by Tenant prior to such Term Expiration Date without expense to Landlord. Any and all such alterations, including, Alterations may be done by any contractor chosen by Tenant provided any such contractor is reputable, bondable by reputable bonding companies, carries the kind of insurance and in the amounts set forth herein, and will work in harmony with Landlord's contractors and laborers in the Building; Tenant in making any alterations, including Alterations, shall cause all work to be done in a good and workmanlike manner using materials substantially equal to or better than those used in the construction of the Premises or original Tenant's Work and shall comply with or cause compliance with all laws and with any direction given by any public officer pursuant to law. Tenant shall obtain or cause to be obtained and maintain in effect, as necessary, all building permits, licenses, temporary and permanent certificates of occupancy and other governmental approvals which may be required in connection with the making of the alterations, including the Alterations. Landlord shall cooperate with Tenant in the obtaining thereof and shall execute any documents reasonably required in furtherance of such purpose, provided any such cooperation shall be without expense and/or liability to Landlord. At least annually if such Alterations or any other alterations hereunder have occurred during the past calendar year, Tenant shall furnish to Landlord as-built sepias and, if applicable, operating manuals, or, at Landlord's option and only if Tenant's computer system is compatible with that of Landlord's, computer disk specifications compatible with Landlord's computer system of the work done by Tenant during such past year and copies of all permits issued in connection therewith. Tenant shall have its contractor procure and maintain in effect during the term of such alterations, including Alterations, satisfactory insurance coverages with an 35 39 insurance company or companies authorized to do business in the Commonwealth of Massachusetts, and shall, upon Landlord's request, furnish Landlord with certificates thereof; 6.1.16 Holdover - To pay to Landlord two hundred percent (200%) the total of the Fixed and additional rent then applicable for each month or portion thereof Tenant shall retain possession of the Premises or any part thereof after the termination of this Lease, whether by lapse of time or otherwise and, also to pay all damages sustained by Landlord on account thereof; provided, however (i) Tenant shall be responsible to pay to Landlord only one hundred fifty percent (150%), and not two hundred percent (200%) as aforesaid, of the total Fixed Rent and additional rent then applicable for the first thirty (30) days Tenant retains possession of the Premises or any part thereof after termination of this Lease, and (ii) during such initial thirty (30) day period only, Landlord hereby acknowledges and agrees that no consequential damages shall be due from Tenant hereunder. The provisions of this subsection shall not operate as a waiver by Landlord of any right of re-entry provided in this Lease; 6.1.17 Hazardous Materials - Tenant shall not (either with or without negligence) cause or permit the escape, disposal or release of any biologically or chemically active or other hazardous substances or materials onto the Premises or the Lot, except in accordance with the requirements of applicable laws and regulations. Tenant shall not allow the storage or use of such substances or materials in any manner not permitted by law, nor allow to be brought into the Premises any such materials or substances except to use in the ordinary course of Tenant's business. Upon Landlord's written request, Tenant shall furnish to Landlord an inventory of the identity of such substances or materials used in the ordinary course of Tenant's business. Without limitation, hazardous substances and materials shall include those described in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section 9601 et seq., the Resource Conservation and Recovery Act, as amended, 42 U.S.C. Section 6901 et seq., the Massachusetts Hazardous Waste Management Act, as amended, M.G.L. c.21C, the Massachusetts Oil and Hazardous Material Release Prevention and Response Act, as amended, M.G.L. c.21E, any applicable local ordinance or bylaw, and the regulations adopted under these acts, as amended (collectively, the "Hazardous Waste Laws"). If any lender or governmental agency shall ever require testing to ascertain whether or not there has been any release of hazardous substances or materials, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand as additional charges if and only if the following conditions are satisfied; (i) if such requirement applies to the Premises and (ii) if an independent, reputable third party engineer employed by Landlord or persons acting under Landlord conclusively determines that such release had been or is likely to have been solely and exclusively caused by Tenant or persons acting under Tenant. If Tenant receives from any federal, state or local governmental agency any notice of violation or alleged violation of any Hazardous Waste Law, 36 40 or if Tenant is obligated to give any notice under any Hazardous Waste Law, Tenant agrees to forward to Landlord a copy of any such notice within three (3) days of Tenant's receipt or transmittal thereof. In addition, Tenant shall execute affidavits, representations and the like from time to time at Landlord's request concerning Tenant's best knowledge of belief regarding the presence of hazardous substances or materials on the Premises. In all events, Tenant shall indemnify Landlord in the manner provided in Section 6.1.7 of this Lease from any release of hazardous substances or materials on the Premises or elsewhere in the Park to the extent caused by Tenant or persons acting under Tenant. Landlord retains the right to inspect the Premises at all reasonable times, upon reasonable notice to Tenant, to ensure compliance with this paragraph. The within covenants shall survive the expiration or earlier termination of the Lease Term; 6.1.18 Signs - Tenant shall not, without prior written consent of Landlord (which such consent shall not be unreasonably withheld or denied but may be withheld in Landlord's sole discretion if Tenant is not then leasing (including subleasing) one hundred percent (100%) of the initial Building, expressly excluding any expansion hereunder), (a) place any exterior signs visible outside the Building, on the Lot or the Premises or anywhere on the exterior of the Building, or (b) place any curtains, blinds (other than standard vertical blinds), shades, awnings, or flagpoles, or the like, in the Premises or anywhere on or in the Building visible from outside the Premises, except as otherwise expressly set forth below in this Section 6.1.18 or elsewhere in this Lease. Tenant shall pay the expenses involved in the erection of any sign and of obtaining all necessary permits and approvals therefor. Except as otherwise provided below with respect to the initial Building signage, Tenant warrants that it shall obtain (and furnish copies thereof to Landlord) all necessary permits and approvals in compliance with local codes and ordinances prior to erecting any such sign(s). Tenant shall remove any of such sign(s) erected by Tenant or on behalf of Tenant upon the termination of this Lease. In connection with Tenant's initial Building signage, Landlord shall use reasonable efforts to obtain, on Tenant's behalf, all necessary permits and approvals required pursuant to local codes and ordinances for the building and site signage (i.e., two exterior signs on the Building and a monument sign consistent with the other signs in the Park). Tenant's signage on the Building shall be exclusive until such time as Tenant fails to lease (including subleasing) at least one hundred percent (100%) of the Building. Tenant shall reimburse Landlord for the actual third-party reasonable costs and expenses incurred by Landlord in connection with obtaining said permits and approvals, including reasonable attorneys fees and disbursements. Tenant agrees to cooperate with Landlord during the permitting process by (i) promptly executing the necessary documentation reasonably requested by Landlord, and (ii) by furnishing the same to Landlord promptly upon Landlord's request, but in no event later than seven (7) days following Landlord's request. Further, the construction and erection of any 37 41 such signage shall be Tenant's sole responsibility and at Tenant's sole cost and expense; 6.1.19 Tenant's Authority - Tenant has the power and authority to enter into this Lease and perform the obligations of Tenant hereunder. This Lease and all other documents executed and delivered by Tenant in connection herewith constitute legal, valid, binding and enforceable obligations of Tenant; and 6.1.20 Confidentiality - This Lease document is a confidential document by and between Landlord and Tenant and Tenant agrees that this Lease shall not be copied and distributed or circulated to any person(s) other than to such parties, and their respective mortgagees, successors or assigns, their legal counsel or their accountants or to any prospective sublessees and assignees or affiliates of Tenant, or to any prospective acquirers, investors, or lenders of Tenant, or to regulatory authorities, or to the directors, shareholders or officers of Tenant, or as required by law, without the prior written consent of Landlord. Nothing contained in this Section shall prohibit the disclosure by Tenant of the essential terms of this Lease. ARTICLE VII CASUALTY AND TAKING 7.1 CASUALTY AND TAKING In case during the Term all or any substantial part of the Premises, and/or the Building Parking Area, or any part thereof, or both (i.e. in the case of a fire or casualty, requiring greater than twelve (12) months to rebuild in Landlord's reasonable judgment; or in the case of a condemnation or a taking, more than thirty-five percent (35%) of the floor area of the Premises or any material part of the means of access thereto or more than twenty-five percent (25%) of Building Parking Area) are damaged by fire or any other casualty or by action of public or other authority in consequence thereof or are taken by eminent domain Landlord shall give prompt notice, (i.e. within thirty (30) days thereof) to Tenant (the "Landlord's Notice") and this Lease shall terminate at Tenant's election, which may be made by notice given to Landlord within thirty (30) days after the date of Landlord's Notice, which termination shall be effective (i) in the event of a casualty, not less than thirty (30) nor more than sixty (60) days after the date of notice of such termination, and (ii) in the event of eminent domain event, as of the date on which such taking becomes effective and Tenant is deprived of the use and enjoyment of the Premises, or part thereof, and/or the Building Parking Area, or part thereof. If in any such case the Lease is not so terminated, Landlord shall proceed promptly and use due diligence to put the Premises, or part thereof, and/or the Building Parking Area, or part thereof, or in case of taking, what may remain thereof (excluding any items installed by Tenant which Tenant may be permitted to remove upon the expiration of the Term) into as near as possible to the condition and character thereof prior to such damage or taking, and in any event shall apply all insurance proceeds or eminent domain awards received by it toward such work, for use and occupation to the extent permitted by the net award of insurance plus any deductibles and such amounts as Tenant may 38 42 elect to make available for such work as hereinafter provided, or the amount of the eminent domain award, and an equitable proportion of the Fixed Rent and additional rent according to the nature and extent of the injury shall be abated until the Premises or such remainder and the Building Parking Area shall have been put by Landlord in such condition; and in case of a taking which permanently reduces the area of the Premises, an equitable proportion of the Fixed Rent and additional rent shall be abated for the remainder of the Term and an appropriate adjustment shall be made to the Annual Estimated Operating Costs and other additional rent payable hereunder. However, in the case of a casualty, if such damage is not repaired and the Premises, or portion thereof, and/or Building Parking Area or part thereof, restored to the same condition as they were prior to such damage within twelve (12) months from the date of Landlord's Notice, then Tenant, within thirty (30) days from the expiration of such twelve (12) month period or from the expiration of any extension thereof by reason of any Tenant's Delay (as defined in Section 3.2 hereof) and/or Force Majeure (as defined in Section 3.5 hereof and subject to the provisions set forth below) as hereinafter provided, may terminate this Lease by notice to Landlord and Landlord's mortgagee(s), given in accordance with Section 10.3 hereof, specifying a date not more than thirty (30) days after the giving of such notice on which the Term of this Lease shall terminate. Notwithstanding such termination notice by Tenant, in the event that Landlord repairs such damage and restores the Premises to the same condition prior to such casualty during such period, not to exceed thirty (30) days, as specified in Tenant's notice, then such notice of termination given by Tenant to Landlord hereunder shall be null and void and of no further force or effect. The period within which the required repairs may be accomplished hereunder shall be extended by (a) the number of days lost as a result of a Tenant's Delay, as defined in and subject to the provisions of Section 3.2, with such term, however, relating to restoration or repair as referenced herein and not to the initial construction of the Building, and (b) the number of days lost as a result of Force Majeure, as defined in Section 3.5 (up to a maximum of forty-five (45) days in the aggregate as aforesaid). If less than a substantial part of the Premises or Lot, or portion thereof, and/or the Building Parking Area, or portion thereof (i.e. in the case of a fire or casualty, requiring less than twelve (12) months to rebuild in Landlord's reasonable judgment; or in the case of a condemnation or taking thirty-five percent (35%) or less of the floor area of the Premises or any part of the means of access thereto or twenty-five percent (25%) or less of the Building Parking Area) are damaged by fire or any other casualty or are taken by eminent domain, then Landlord shall give prompt notice (i.e. within thirty (30) days) thereof to Tenant, which notice shall specify Landlord's estimation of the time period within which such repairs shall be completed, and thereafter Landlord shall proceed promptly and with due diligence to the extent permitted by the net award of insurance plus any deductible amounts and such amount as Tenant may elect to make available for such work as hereinafter provided, or the amount of the eminent domain award. In the event that Landlord fails to repair such damage and restore the Premises to substantially the same condition prior to such fire and other casualty within the time period as reasonably estimated by Landlord, but in no event greater than such twelve (12) month period from the date of such Landlord's notice to Tenant, or any extension thereof permitted for delays lost due to any Tenant's Delay and/or Force Majeure (as hereinbefore provided), then Tenant 39 43 may terminate this Lease by written notice to Landlord and to Landlord's mortgagee(s), as provided in Section 10.3 hereof, specifying a date not more than thirty (30) days after the giving of such notice on which the Term of this Lease shall terminate. Notwithstanding such termination notice by Tenant, in the event that Landlord repairs such damage and restores the Premises to substantially the same condition prior to such fire or other casualty during such period, not to exceed thirty (30) days, as specified in Tenant's notice, then such notice of termination given by Tenant to Landlord hereunder shall be null and void and of no further force and effect. If less than a substantial part of the Premises and/or the Building Parking Area shall be so damaged, then Fixed Rent and additional rent due hereunder shall be equitably abated until the Premises and/or the Building Parking Area are so restored as set forth hereunder. Landlord's architect's certificate, given in good faith, shall be deemed conclusive 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 Section, except in the event of disagreement between Landlord and Tenant relating to this Section, in which event the dispute resolution provisions of Section 3.6 shall apply. Notwithstanding any language to the contrary, Landlord may construct "Replacement Parking" pursuant to the following: If not more than thirty-five percent (35%) of the Building Parking Area shall be so damaged, taken, appropriated, or condemned as aforesaid, then Landlord or Tenant may elect to provide Replacement Parking and render Tenant's notice of termination nugatory (if applicable) by, within thirty (30) days following the effective date of such destruction, taking, appropriation or condemnation, giving to Tenant notice in writing that Landlord will, at Landlord's expense, construct replacement parking spaces of the same quantity and quality and convenience as the parking spaces so taken, appropriated or condemned (i.e., Landlord using best efforts to locate the replacement parking spaces as close to the Building as possible). Any of such Replacement Parking shall be constructed by Landlord within a reasonable time period following the effective date of such destruction, taking, appropriation or condemnation, but in no event later than thirty (30) days after the occurrence of such destruction, taking, appropriation or condemnation, it being agreed by Landlord and Tenant that such time period shall be extended to include weather-related delays as aforesaid, in which event such Replacement Parking will be completed as reasonably possible thereafter, Landlord agreeing to proceed promptly and with due diligence to complete construction of any Replacement Parking. Landlord and Tenant acknowledge that if Landlord is prevented from performing the final paving for said Replacement Parking on account of weather, such final paving may be performed as soon thereafter as is feasible. Such notice shall be accompanied by (A) a site plan showing (i) the location of the Replacement Parking spaces, and (B) an opinion from counsel for Landlord that such Replacement Parking may be constructed as-of-right under then applicable zoning and land use regulations. 40 44 In the event of any other taking of the Premises, or any part thereof, for temporary use or for less than one (1) year, (i) this Lease shall be and remain unaffected thereby; and (ii) Landlord shall pay to Tenant its pro rata share of any such use, provided that if any taking is for a period extending beyond the Term of this Lease, such award shall be appointed between Landlord and Tenant as of the Term Expiration Date. Tenant has the option but not the obligation, in any fire or other casualty which creates a Landlord repair obligation in accordance with the terms of this Section to make available for such reconstruction all or a portion of the amount by which the cost of repair as certified by Landlord's architect exceeds the amount of proceeds received by Landlord. 7.2 RESERVATION OF AWARD Landlord reserves to itself any and all rights to receive awards made for damages to the Premises or Lot and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby releases and assigns to Landlord all Tenant's rights to such awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request. It is agreed and understood, however, that Landlord does not reserve to itself, and Tenant does not assign to Landlord, any damages payable for (i) movable trade fixtures installed by Tenant or anybody claiming under Tenant, at its own expense, or (ii) relocation expenses recoverable by Tenant from such authority in a separate action, or (iii) the value of Tenant's improvements installed in the Premises by or on behalf of Tenant, but not by Landlord. 7.3 ADDITIONAL CASUALTY PROVISIONS (a) Landlord shall not be required to repair or replace any of Tenant's business machinery, equipment, cabinet work, furniture, personal property or other installations not originally installed by Landlord. (b) In the event of any termination of this Lease pursuant to this Article VII, 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 Term Expiration Date, and Landlord shall assist Tenant to the extent necessary to secure Tenant's share of any insurance award relative to the Tenant's Work hereunder. Tenant shall have access to the Premises at Tenant's sole risk for a period of thirty (30) days after the date of termination in order to remove Tenant's personal property except as prohibited by any applicable governmental agency or official. (c) Notwithstanding any language to the contrary contained in this Article VII, if all or any substantial part of the Premises and/or the Building Parking Areas or any part thereof (as hereinabove defined), shall be damaged by fire or other casualty or taken by eminent domain during the last two (2) years of the Term of this Lease or the last two (2) years of either of the Extended Terms, as the case may be, then either Landlord or Tenant may terminate this Lease effective as of the date of such fire or other casualty or taking upon notice to the other as 41 45 aforesaid, except that Tenant may render Landlord's notice of termination nugatory by exercising early its option to extend the initial Term, or the applicable Extended Term, as the case may be, of this Lease for five (5) additional years in accordance with Exhibit F. In the event of such early exercise, Landlord and Tenant agree to determine the Fixed Rent for the applicable Extended Term at least nine (9) months prior to the commencement date of the applicable Extended Term in accordance with and in the manner set forth in said Exhibit F. ARTICLE VIII RIGHTS OF MORTGAGEE 8.1 PRIORITY OF LEASE Landlord shall have the option to subordinate this Lease to any mortgagee or deed of trust of the Lot or Premises, or both ("the mortgaged premises"), provided that the holder thereof enters into a Subordination, Non-Disturbance and Attornment Agreement substantially in the form attached hereto as Exhibit J (or such other form mutually agreeable to Landlord, Tenant and Landlord's mortgagee, each party agreeing to reasonably cooperate with each other in reaching mutual agreement on the content of any such other form, so long as such other form does not substantially reduce or alter Tenant's rights or obligations thereunder). 8.2 LIMITATION ON MORTGAGEE'S LIABILITY Upon entry and taking possession of the mortgaged premises for any purpose other than foreclosure, the holder of a mortgage shall have all rights of Landlord, and during the period of such possession, the duty to perform all Landlord's obligations hereunder. Except during such period of possession, no such holder shall be liable, either as mortgagee or as holder of a collateral assignment of this Lease, to perform, or be liable in damages for failure to perform any of the obligations of Landlord unless and until such holder shall enter and take possession of the mortgaged premises for the purpose of foreclosing a mortgage. Upon entry for the purpose of foreclosing a mortgage, such holder shall be liable to perform all of the obligations of Landlord, subject to the provisions of Section 8.3 provided that a discontinuance of any foreclosure proceeding shall be deemed a conveyance under the provisions of Section 10.4 to the owner of the equity of the mortgaged premises. From and after making entry and taking possession of the Premises, any such mortgagee shall be fully and completely liable for the obligations hereunder. 8.3 MORTGAGEE'S ELECTION Intentionally Deleted. 8.4 NO PREPAYMENT OR MODIFICATION, ETC. No Fixed Rent, additional rent, or any other charge shall be paid more than thirty (30) days prior to the due dates thereof, and payments made in violation of this provision shall (except to the extent that such payments are actually received by a mortgagee in possession or in the process of foreclosing its mortgage) be a nullity as against such mortgagee. No assignment of 42 46 this Lease (excepting only in accordance with the provisions of this Lease) and no agreement to make or accept any surrender, termination or cancellation of this Lease (excepting only in accordance with the provisions of this Lease) and no agreement to modify so as to reduce the rent, change the Term, or otherwise materially change the rights of Landlord under this Lease, or to relieve Tenant of any obligations or liability under this Lease, shall be valid unless consented to in writing by Landlord's mortgagees of which Tenant has received notice. 8.5 NO RELEASE OR TERMINATION 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 thirty (30) days prior written notice of Landlord's act or failure to act to Landlord's mortgagees of which Landlord has provided written notice to Tenant, if any, 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 reasonable time thereafter, but nothing contained in this Section 8.5 shall be deemed to impose any obligation on any such mortgagee to correct or cure any such condition. "Reasonable time" as used above means and includes a reasonable time to obtain possession of the mortgaged premises, if the mortgagee elects to do so, and a reasonable time to correct or cure the condition if such condition is determined to exist, however, in no event shall such time extend beyond sixty (60) days from the date Tenant provides notice to Landlord's mortgagee(s) as aforesaid. 8.6 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 VIII) 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, and such mortgagee shall be entitled to enforce such provisions in its own name. Tenant agrees on request of Landlord to execute and deliver from time to time any agreement which may reasonably be deemed necessary to implement the provisions of this Article VIII. 8.7 SUBMITTAL OF FINANCIAL STATEMENT At any time, but not more than annually during the Term of this Lease, and only to the extent Tenant becomes a publicly traded company, within fifteen (15) days after request therefor by Landlord (i.e. if requested by Landlord' mortgagee(s)), Tenant shall supply to Landlord and/or any mortgagee of Landlord a current financial statement, which such financial statement may be given by Tenant to Landlord in the form of Tenant's current annual report, or such other financial information as may be reasonably required by any such party. Landlord agrees to use diligent efforts to keep such information confidential and to request Landlord's mortgagee to keep such information confidential. 43 47 ARTICLE IX DEFAULT 9.1 EVENTS OF DEFAULT BY TENANT It shall be an Event of Default under this Lease, if (i) Tenant fails to pay Fixed Rent or additional rent for more than ten (10) days, after notice thereof specifying such failure and that such failure may be an Event of Default hereunder; (ii) Tenant fails to perform its other non-monetary obligations hereunder for more than thirty (30) days after notice thereof from Landlord, together with such additional time, if any, as is reasonably required to cure the default if the default is of such a nature that it cannot reasonably be cured in thirty (30) days; or (iii) if Tenant makes any assignment for the benefit of creditors, or files a petition under any bankruptcy or insolvency law; or (iv) if such a petition is filed against Tenant and is not dismissed within sixty (60) days; or (v) if a receiver becomes entitled to Tenant's leasehold hereunder and it is not returned to Tenant within ninety (90) days; or (vi) such leasehold is taken on execution or other process of law in any action against Tenant; then, and in any such cases, Landlord and the agents and servants of Landlord may, in addition to and not in derogation of any remedies for any preceding breach of covenant, immediately or at any time thereafter while such default continues and without further notice, enter into and upon the Premises or any part thereof in the name of the whole or mail a notice of termination addressed to Tenant at the Premises and repossess the same as of Landlord's former estate and expel Tenant and those claiming through or under Tenant and remove its and their effects without being deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used for arrears of rent or prior breach of covenant, and upon such entry or mailing as aforesaid, this Lease shall terminate, but Tenant shall remain liable as hereinafter provided. After the occurrence of an Event of Default as aforesaid, Tenant hereby waives all statutory rights of redemption, if any to the extent such rights may be lawfully waived, and Landlord, without notice to Tenant, may store Tenant's effects and those of any person claiming through or under Tenant at the expense and risk of Tenant and, if Landlord so elects, may sell such effects at public auction or private sale and apply the net proceeds to the payment of all sums due to Landlord from Tenant, if any, and pay over the balance, if any, to Tenant. 9.2 TENANT'S OBLIGATIONS AFTER TERMINATION In the event that this Lease is terminated under any of the provisions contained in Section 9.1, Tenant covenants to pay forthwith to Landlord, as compensation, a single lump-sum payment equal to the excess of the net present value of the total rent reserved for the residue of the Term (exclusive of any unexercised Extended Term(s) remaining at the time of termination) over the fair market rental value of the Premises (including additional rent) for said residue of the Term estimated as of the date of termination. If Landlord does not receive a single lump-sum payment from Tenant as aforesaid, Tenant covenants and agrees to pay punctually to Landlord all the sums and perform all the obligations which Tenant covenants in this Lease to pay and to perform in the same manner and to the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by Tenant under the foregoing covenants, 44 48 Tenant shall be credited with any amount paid to Landlord as compensation as provided in the first sentence of this Section 9.2 and also with the net proceeds of any rents obtained by Landlord by reletting the Premises, after deducting all Landlord's expenses in connection with such reletting, including, without implied limitation, all repossession costs, brokerage commissions, reasonable fees for legal services and reasonable expense of preparing the Premises for such reletting, it being agreed by Tenant that Landlord may (i) relet the Premises or any part or parts thereof for a term or terms which may, at Landlord's option, be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term and may grant such concessions and free rent as Landlord in its sole judgment considers advisable or necessary to relet the same, and (ii) make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary to relet the same, and no action of Landlord in accordance with the foregoing on failure to relet or to collect rent under reletting shall operate or be construed to release or reduce Tenant's liability as aforesaid. Landlord hereby agrees in all events to use reasonable efforts and due diligence to mitigate the foregoing damages and to relet the Premises. Nothing contained in this Lease shall, however, limit or prejudice the right of Landlord to prove and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. ARTICLE X MISCELLANEOUS 10.1 TITLES The titles of the Articles are for convenience and are not to be considered in construing this Lease. 10.2 NOTICE OF LEASE Concurrently with the executing of this Lease, Landlord and Tenant have executed and recorded a notice of lease in the form attached hereto as Exhibit T. If this Lease is terminated before the Term expires the parties will execute an instrument in such form acknowledging the date of termination. 10.3 NOTICES FROM ONE PARTY TO THE OTHER No notice, approval, consent requested or election required or permitted to be given or made pursuant to this Lease shall be effective unless the same is in writing. Communications shall be addressed, if to Landlord, at Landlord's Address with a copy to Paul A. Hedstrom, Esq., Hinckley, Allen & Snyder LLP, 28 State Street, Boston, Massachusetts 02109, or at such other address as may have been specified by prior notice to Tenant and, if to Tenant, at Tenant's 45 49 Address with a copy to Diane M. McDermott, Esq., Gadsby & Hannah, LLP, 225 Franklin Street, Boston, Massachusetts 02110 and to Suzanne M. Zabitchuck, Esq., c/o Siemens Corporation, 200 Wheeler Road, Burlington, Massachusetts 01803 or at such other place as may have been specified by prior notice to Landlord. Any communication so addressed shall be deemed duly served if actually received or delivery is refused at the foregoing addresses mailed by registered or certified mail, return receipt requested, delivered by hand, or by overnight express service by a carrier providing a receipt of delivery. 10.4 BIND AND INURE The obligations of this Lease shall run with the land, and this Lease shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and assigns, except that the Landlord named herein and each successive owner of the Premises shall be liable only for the obligations accruing during the period of its ownership, said liability terminating as to future liability upon termination of such ownership and passing to the successor in ownership. Neither the Landlord named herein nor any successive owner of the Premises whether an individual, trust, a corporation or otherwise shall have any personal liability beyond their equity interest in the Premises. 10.5 NO SURRENDER The delivery of keys to any employees of Landlord or to Landlord's agent or any employee thereof shall not operate as a termination of this Lease or a surrender of the Premises. 10.6 NO WAIVER, ETC. The failure of Landlord or of Tenant to seek redress for violation of, or to insist upon the strict performance of any covenant or condition of this Lease or, with respect to such failure of Landlord, any of the Rules and Regulations or Park Covenants referred to in Section 6.1.4, whether heretofore or hereafter adopted by Landlord, shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation, nor shall the failure of Landlord to enforce any of said Rules and Regulations or Park Covenants against any other tenant in the Park be deemed a waiver of any such Rules or Regulations or Park Covenants, as applicable. The receipt by Landlord of Fixed Rent or additional rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach by Landlord, unless such waiver shall be in writing signed by Landlord. No consent or waiver, express or implied, by Landlord or Tenant to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same agreement or duty in a previous or subsequent instance, or any other agreement or duty. 10.7 NO ACCORD AND SATISFACTION No acceptance by Landlord of a lesser sum than the Fixed Rent and additional rent then due shall be deemed to be other than on account of the earliest installment of such rent due, nor 46 50 shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed as accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such installment or pursue any other remedy in this Lease provided. 10.8 CUMULATIVE REMEDIES The specific remedies to which Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions. 10.9 PARTIAL INVALIDITY If any term of this Lease, or the application thereof to any person or circumstances shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such term to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each term of this Lease shall be valid and enforceable to the fullest extent permitted by law. 10.10 RIGHT TO CURE (a) If Tenant shall at any time fail to perform its obligation in accordance with the provisions of this Lease and Tenant does not commence the cure of such failure within thirty (30) days of notice thereof (except in the event of emergencies), and thereafter diligently prosecute such cure to completion, then Landlord shall have the right, but shall not be obligated, to enter upon the Premises and to perform such obligation, notwithstanding the fact that no specific provision for such substituted performance by Landlord is made in this Lease with respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by Landlord (together with interest at the rate set forth in Section 4.3 hereof), and all necessary incidental reasonable third party costs and expenses in connection with the performance of any such acts by Landlord, shall be deemed to be additional rent under this Lease and shall be payable to Landlord immediately on demand.

ESTOPPEL - Tenant hereby certifies to Lender that, as of the date of this Agreement: (i) the Lease, as described above, is the true, correct and complete Lease and has not been modified or amended and constitutes the entire agreement between Landlord and Tenant, (ii) to the best of Tenant's knowledge, without inquiry, there are no defaults of Landlord under the Lease and there are no existing circumstances which with the passage of time, or giving of notice, or both, would give rise to a default under the Lease and/or allow Tenant to terminate the Lease, and (iii) Tenant is satisfied with all of the work done by and required of Landlord to date, such work has been done in accordance with plans and specifications approved by Tenant, and as of the date hereof Tenant is not aware of any defect in the work or has not rejected any of the work done by Landlord on the Leased Premises. If this Agreement is being delivered prior to completion of all of Landlord's Work (as such term is defined in the Lease) on the Leased Premises, Tenant agrees that, promptly after request of the Lender therefor, it will provide an estoppel certificate to Lender following completion of such work indicating whether Tenant has accepted the work and begun payment of rent. 2. NON-DISTURBANCE - Lender agrees that if Lender comes into possession of or acquires title to all or any part of the Leased Premises or the Lot (as defined in the Lease) as a result of foreclosure or other enforcement of the Security Deed or the Assignment of Leases, or both, then so long as no default under the Lease by Tenant exists and continues beyond the expiration of all applicable cure periods (after notice, if any, required by the Lease) as would entitle the lessor under the Lease to terminate the Lease or would cause, without any further action on the part of such lessor, the termination of the Lease or would entitle the lessor under the Lease to exercise any other remedy available to it on account of Tenant defaults under the Lease, the Lease shall not be terminated, nor shall Tenant's use, possession or enjoyment of the Leased Premises and appurtenant rights and interests or rights under the Lease be interfered with. Following a foreclosure or other action or proceeding in the nature of foreclosure instituted under or in connection with the Security Deed or the Assignment of Leases, or the acquisition of title to the Leased Premises, the person or entity acquiring the interest of the lessor under the Lease as a result of any such action or proceeding or deed in lieu of any such action or proceeding (hereinafter called the "Purchaser") or Lender if Lender takes possession of the Property shall have all rights and obligations of Landlord under the Lease, except as expressly otherwise set forth herein, provided, however, that neither the Purchaser nor the Lender shall be (a) liable for any act or omission of any prior lessor under the Lease provided that nothing herein shall relieve such Purchaser or Lender from curing any continuing defaults of lessor after receipt of requisite notices from Tenant, all in accordance with the Lease; or (b) liable for the return of any security deposit which lessee under the Lease has paid under the Lease unless such security deposit is received by Lender; or (c) subject to any offsets or defenses which the lessee under the Lease might have against any prior lessor under the Lease unless Lender has received prior written notice of the offset or defense and opportunity to cure the same in accordance with Section 7 below; or (d) bound by any base rent, or any other payments which the lessee under the Lease might have paid for more than the current month to any prior lessor under the Lease; or (e) bound by any amendment or modification of the Lease made without Lender's prior written consent (Lender hereby agreeing not to unreasonably withhold or delay its consent); or (f) bound by any assignment or sublease of the lessee's interest in the Lease made without obtaining Lender's prior written consent (such consent not to be unreasonably withheld or delayed), except where the consent of the Landlord is 2 100 not required pursuant to the provisions of Section 6.1.6 of the Lease (in which event no consent of Lender shall be required); or (g) personally liable for any default under the Lease or any covenant or obligation on its part to be performed thereunder as lessor, it being acknowledged that Tenant's sole remedy in the event of such default shall be to proceed against Purchaser's or Lender's interest in the Property and the rents, or other proceeds arising therefrom. In the event that Lender acquires title to or possession of all or any part of the Leased Premises, whether pursuant to a foreclosure proceeding or otherwise, then within thirty (30) days thereafter, the Lender may elect to deliver a written notice to the Tenant stating that either (i) the Lender intends to perform the construction obligations of the Landlord set forth in Article III of the Lease (the "Construction Obligations"), or (ii) the Lender does not intend to perform the Construction Obligations. A notice delivered by the Lender pursuant to clause (i) is referred to herein as an "Opt-In Construction Notice" and a notice delivered by the Lender pursuant to clause (ii) is referred to herein as an "Opt-Out Construction Notice". In the event that the Lender does not deliver either an Opt-Out construction Notice or an Opt-In Construction Notice to the Tenant within said thirty (30) days after acquisition of title or possession, then Tenant may elect to deliver a written request (a "Construction Confirmation Request") to the Lender, requesting that Lender deliver either an Opt-Out Construction Notice or an Opt-In Construction Notice. If either (a) Lender delivers an Opt-Out Construction Notice to Tenant as aforesaid, or (b) Lender does not deliver an Opt-In Construction Notice to Tenant by not later than thirty (30) days after receipt of Tenant's Construction Confirmation Request, then Lender shall not be obligated to perform the Construction Obligations in accordance with the terms and provisions the Lease. If Lender delivers an Opt-In Construction Notice as aforesaid, then Lender shall be obligated to perform the Construction Obligations in accordance with the terms and provisions of the Lease. If Lender timely delivers an Opt-Out Construction Notice to Tenant by not later than thirty (30) days after receipt of Tenant's Construction Confirmation Request as aforesaid, or Lender does not deliver an Opt-In Construction Notice to Tenant by not later than thirty (30) days of its receipt of Tenant's Construction Confirmation Request, then (a) Lender shall have no obligation to perform the Construction Obligations, and (b) Tenant may elect to terminate the Lease by providing written notice of such election to Lender. If Tenant elects to terminate the Lease, the Lease shall be terminated effective as of the date specified in Tenant's notice. Thereafter the Lease shall be null and void and of no further force or effect, and neither the Tenant nor the Lender shall have any further liabilities or obligations thereunder. If (a) Lender sells, conveys, assigns, pledges or transfers its interest in the Loan, or (b) Lender sells the Leased Premises, or any part thereof, at a foreclosure sale, or (c) if Lender acquires title to the Leased Premises and subsequently conveys the Leased Premises, then, in any such event, concurrently with such transaction, Lender shall transfer, assign and convey all right, title and interest of the Lender in and to the Security Deposit then held by it, if applicable, to such purchaser, assignee, or transferee. Notwithstanding anything to the contrary contained in this Section, if Lender so transfers, assigns or conveys all right, title and interest of the Lender in and to the Security Deposit, if applicable, as aforesaid, then Lender shall have no liability for the return of the Security Deposit. 3 101 3. ATTORNMENT - Unless the Lease is terminated in accordance with Paragraph 2 or in accordance with the terms of the Lease, if the interests of the lessor under the Lease shall be transferred by reason of the exercise of the power of sale contained in the Security Deed (if applicable), or by any foreclosure or other proceeding for enforcement of the Security Deed, or by deed in lieu of foreclosure or such other proceeding, or if Lender takes possession of the Property pursuant to any provisions of the Security Deed, Tenant shall be bound to the Purchaser or Lender, as the case may be, under all of the terms, covenants and conditions of the Lease for the balance of the term thereof and any extensions or renewals thereof which may be effected in accordance with any option therefor in the Leases with the same force and effect as if the Purchaser or Lender were the lessor under the Lease, and Tenant, as lessee under the Lease, does hereby agree to attorn to the Purchaser and Lender if it takes possession of the Property, as its lessor under the Lease. Such attornment shall be effective and self-operative without the execution of any further instruments upon succession by Purchaser to the interest of the lessor under the Lease or the taking of possession of the Property by Lender. Nevertheless, Tenant shall, from time to time, execute and deliver such instruments evidencing such attornment as Purchaser or Lender may reasonably require. The respective rights and obligations of Purchaser, Lender and of the lessee under the Lease upon such attornment, to the extent of the then remaining balance of the term of the Lease and any such extensions and renewals, shall be and are the same as now set forth in the Lease, except as otherwise expressly provided in Paragraph 2 above. 4. SUBORDINATION - Subject to the provisions of this Agreement, Tenant hereby subordinates all of its rights, title and interest as lessee under the Lease to the right, title and interest of Lender under the Security Deed, and Tenant further agrees that the Lease now is and shall at all times continue to be subject and subordinate in each and every respect to the Security Deed and to any and all increases, renewals, modifications, extensions, substitutions, replacements and/or consolidations of the Security Deed and to all sums secured thereby with the same force and effect as if the Security Deed had been executed, delivered and recorded prior to the execution and delivery of the Lease. 5. OTHER CONDITIONS - Notwithstanding anything to the contrary contained in this Agreement or in the Lease, Lender, Tenant and Landlord agree: (a) that to the extent required by the Lease, and provided that (i) Tenant has not defaulted in the payment of rent or other charges under the Lease, (ii) Landlord has not defaulted in the payment of debt service or other payments under the loan documents and (iii) neither Landlord or Tenant has filed a voluntary petition in bankruptcy under Title 11 of the United States Code or had an order for relief issued against it and not dismissed within thirty (30) days of issuance or has filed any petition or answer seeking or acquiescing in any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief for itself under any present or future federal, state or other law or regulation relating to bankruptcy, insolvency or other relief of debtors or consented or acquiesced in the appointment of any custodian, trustee, receiver, conservator or liquidator for it or all or any substantial part of its property or made an assignment for the benefit of creditors, then in the event of an insured casualty to the Leased Premises, and if Landlord satisfies the conditions provided for hereafter, Lender shall hold the balance of any casualty proceeds after proof and adjustment and shall use such funds for the following purposes: (x) to pay costs and obligations secured by the Security Deed (the "Secured Obligations") as such become due during the course of reconstruction or repair of the Leased Premises (y) to reimburse Landlord, in accordance with the terms and conditions set forth below, for the costs of reconstruction or repair of the Leased Premises, and (z) upon completion of such reconstruction or repair, to apply any excess to the payment of the Secured Obligations. Such funds shall be made available as provided above upon the Landlord's prior 4 102 satisfaction of such conditions as the Lender may reasonably establish with respect thereto (each of which must be complied with in a manner reasonably satisfactory to the Lender, with all documents, instruments, agreements, or evidence to be in form and substance satisfactory to the Lender), including without limitation, the following (hereinafter referred to as the "Funding Requirements"): (i) delivery of estoppel certificate(s) or other satisfactory evidence that the Lease remains in full force and effect and will remain in full force and effect after such repair and restoration, without any right of termination or cancellation during the projected course of said repair or restoration; (ii) delivery of plans and specifications, construction budget, construction contract, and construction schedule for such repair and restoration, satisfactory to Lender; (iii) delivery of evidence of compliance with all applicable state, federal, and local laws, ordinances and regulations relating to such repair and restoration, and the issuance of all required permits, licenses and approvals relative thereto; (iv) delivery of evidence of the availability of any funds necessary to complete such repairs and restoration in excess of such proceeds, which funds, at the request of the Lender, shall be deposited with the Lender to be disbursed with such proceeds; (v) builder's all risk insurance; (vi) rent loss insurance sufficient to pay all operating costs and debt service confirmed by the insurer to be available for the period of repair and restoration; (vi) evidence that the insurer under such policies of fire or other casualty insurance does not assert any defense to payment under such policies against Lender, Landlord or any tenant of the Leased Premises; (vii) execution of any documentation deemed reasonably necessary by the Lender to provide for the disbursement of such funds in a manner typical to a construction loan; (viii) delivery of evidence that the repair or restoration can be completed prior to the then applicable maturity date of the note; (ix) Landlord delivers to Lender a written undertaking to expeditiously commence and to satisfactorily complete with due diligence the necessary restoration; and (x) compliance of such other reasonable non-financial terms and conditions customary for construction loans of the size and scope involved with such repairs and restoration. 6. ASSIGNMENT OF LEASES - Tenant hereby acknowledges that all of Landlord's right, title and interest as lessor under the Lease is being duly assigned to Lender pursuant to the terms of the Assignment of Leases, and that pursuant to the terms thereof all rental payments under the Lease shall 5 103 continue to be paid to Landlord in accordance with the terms of the Lease unless and until Tenant is otherwise notified in writing by Lender. Upon receipt of any such written notice from Lender, Tenant covenants and agrees to make payment of all rental payments then due or to become due under the Lease directly to Lender or to Lender's agent designated in such notice and to continue to do so until otherwise notified in writing by Lender. Landlord hereby irrevocably directs and authorizes Tenant to make rental payments directly to Lender following receipt of such notice and covenants and agrees that Tenant shall have the right to rely on such notice without any obligation to inquire as to whether any default exists under the Security Deed or the Assignment of Leases or the indebtedness secured thereby, and notwithstanding any notice of claim of Landlord to the contrary, that Landlord shall have no right or claim against Tenant for or by reason of any rental payments made by Tenant to Lender following receipt of such notice. Except as otherwise specifically set forth in the Lease, Tenant further acknowledges and agrees: (a) that under the provisions of the Assignment of Leases, the Lease cannot be terminated (nor can Landlord accept any surrender of the Lease) or modified in any of its terms, or consent be given to the waiver or release of Tenant from the performance or observance of any obligation under the Lease without the prior written consent of Lender, and without such consent, no rent may be collected or accepted by Landlord more than one month in advance; and (b) that the interest of Landlord as lessor under the Lease has been assigned to Lender for the purposes specified in the Assignment of Leases, and Lender assumes no duty, liability or obligation under the Lease, except only under the circumstances, terms and conditions specifically set forth in the Assignment of Leases or this Agreement. 7. NOTICE OF DEFAULT BY LESSOR - Tenant, as lessee under the Lease, hereby covenants and agrees to give Lender written notice properly specifying wherein the lessor under the Lease has failed to perform any of the covenants or obligations of the lessor under the Lease simultaneously with the giving of any notice of such default to the lessor under the provisions of the Lease. Tenant agrees that Lender shall have the right, but not the obligation, within thirty (30) days after receipt by Lender of such notice (or, with respect to non-monetary defaults only, within such additional time as is reasonably required to correct any such default) to correct or remedy, or cause to be corrected or remedied, each such default before the lessee under the Lease may take any action under the Lease by reason of such default; provided however, in no event shall such time extend for more than sixty (60) days after Tenant provides such notice to Lender, except if Lender has commenced to cure any such non-monetary default under the Lease (which shall in no event include foreclosure or exercise of other remedies available under the Security Deed) within thirty (30) days after such written notice to Lender and is diligently proceeding to cure such default and such non-monetary default cannot be cured within sixty (60) days despite such diligent efforts to cure on the part of Lender, in which event such time period may be extended for an additional period of not more than thirty (30) days.

NO FURTHER SUBORDINATION - Except as expressly provided to the contrary in Paragraph 4 hereof, Landlord and Tenant covenant and agree with Lender that there shall be no further subordination of the interest of lessee under the Lease to any lender or to any other party without first obtaining the prior written consent of Lender. Any attempt to effect a further subordination of lessee's interest under the Lease without first obtaining the first written consent of Lender shall be null and void. 9.

In the event of any transfer of the Security Deed or the note secured thereby, the Lender shall transfer and deliver to the transferee any security deposit under the Lease held by Lender or its agent, and provided the transferee assumes the obligations of Lender hereunder or otherwise recognizes the provisions hereof by written instrument, Lender shall thereupon become freed and relieved of all covenants and obligations of the Lender hereunder, except with respect to any breaches of this Agreement as shall have theretofore occurred. 16.

(b) If Tenant delivers Tenant's Rejection Notice and the Market Rent is not otherwise agreed upon by Landlord and Tenant within forty-five (45) days after Landlord's receipt of Tenant's notice that it intends to exercise its option to extend the Term, then the Market Rent shall be determined by the following appraisal procedure: 1. Within five (5) days of the expiration of said forty-five (45) day period, Tenant shall give notice to Landlord, which notice shall specify the name and address of the appraiser designated by Tenant (the "Tenant's Appraisal Notice"). Landlord shall within five (5) days after receipt of Tenant's Appraisal Notice, notify Tenant of the name and address of the appraiser designated by Landlord. Such two appraisers shall, within twenty (20) days after the designation of the second appraiser, make their determinations of the Market Rent in writing and give notice thereof to each other and to Landlord and Tenant. Such two (2) appraisers shall have twenty (20) days after the receipt of notice of each other's determination to confer with each other and to attempt to reach agreement as to the determination of the Market Rent. If such appraisers shall concur in such determination, they shall give notice thereof to Landlord and Tenant and such concurrence shall be final and binding upon Landlord and Tenant. If such appraisers shall fail to concur as to such determination within said twenty (20) day period, they shall give notice thereof to Landlord and Tenant and shall immediately designate a third appraiser. If the two appraisers shall fail to agree upon the designation of such third appraiser within five (5) days after said twenty (20) day period, then they or either of them shall give notice of such failure to agree to Landlord and Tenant and if Landlord and Tenant fail to agree upon the selection of such third appraiser within five (5) days after the appraiser(s) appointed by the parties give notice as aforesaid, then either party on behalf of both may apply to the American Arbitration Association or any successor thereto, or on his or her failure, refusal or inability to act, to a court of competent jurisdiction, for the designation of such third appraiser. 2. All appraisers shall be independent real estate appraisers or consultants who shall have had at least seven (7) years continuous experience in the business of appraising real estate in the suburban Boston area. 117 3. The third appraiser shall conduct such hearings and investigations as he or she may deem appropriate and shall, within ten (10) days after the date of his or her designation, make an independent determination of the Market Rent. 4. If none of the determinations of the appraisers varies from the mean of the determinations of the other appraisers by more than ten (10%) percent, the mean of the determinations of the three (3) appraisers shall be the Market Rent for the Premises. If, on the other hand, the determination of any single appraiser varies from the mean of the determinations of the other two (2) appraisers by more than ten (10%) percent, the mean of the determination of the two (2) appraisers whose determinations are closest shall be the Market Rent. 5. The determination of the appraisers, as provided above, shall be conclusive upon the parties and shall have the same force and effect as a judgment made in a court of competent jurisdiction. 6. Each party shall pay fees, costs and expenses of the appraiser selected by it, its own counsel fees, and one-half (1/2) of all other expenses and fees of any such appraisal. 2 118 EXHIBIT "Q" EXISTING EXCLUSIVE USES AND EXCLUSIONS EXCLUSIONS: Lotus - Building 3 Lease - Novell - Netscape - Microsoft - Hewlett Packard Emerson - Building 7 Lease - Tenants whose principal use is offering medical and diagnostic treatment services and/or health education and wellness promotion educational services Chili's - Restaurant exclusion for 3-mile radium of Westford Technology Park excluding cafeterias in buildings RIGHTS OF FIRST REFUSAL: Lotus - Building 3 Lease - Building 4 - Building 6 Lotus - Building 1 Lease - Building 1 Emerson - Building 7 Lease - Building 7 RIGHTS OF FIRST OFFER: ENSR - Building 2 Lease - Building 2 - any space that becomes available 119 EXHIBIT "R" EXPANSION OPTION Landlord (including Landlord's affiliates, successors and assigns and all other successors in title) agrees it shall hold available, subject to the conditions of this Exhibit R, for Tenant Lot 10E, as described in Exhibit A-1 and in Exhibit N of this Lease (the "Expansion Land") required to support one contiguous expansion of the Building by Landlord for Tenant for a total of up to seventy-five thousand (75,000) rentable square feet of additional space (the "Expansion Space"). Landlord acknowledges and agrees not to construct or permit the construction of any buildings in, on or under the Expansion Land, and not to use the Expansion Land for purposes other than for providing the required parking, additional parking and access to Tenant pursuant to the provisions of Section 10.14 of the Lease, subject to the conditions of this Exhibit R. The size and footprint of the Expansion Space shall be determined by Landlord and Tenant provided, however, that such expansion shall be a three (3) story building consisting of seventy-five thousand (75,000) square feet, and shall provide Tenant with an additional two hundred twenty-two (222) parking spaces, and that the footprint and parking of such expansion shall be within the general building footprint and parking areas shown on the Proposed Expanded Building Footprint & Site Plan, prepared by Symmes, Maini & McKee Associates, dated February 16, 2000, attached as Exhibit N to this Lease (the "Expanded Building Site Plan"), or such other area as is reasonably agreed upon by Landlord and Tenant. So long as there does not then exist any uncured, continuing Event of Default and this Lease is then in existence and in full force and effect, so long as Tenant is then leasing including (subleasing) at least one hundred percent (100%) of the Building, and so long as such expansion option has not been terminated in accordance with paragraph I. of this Exhibit R, Landlord shall be required to hold the Expansion Land available as aforesaid, or to cause an affiliate, successor or assign of Landlord or any other successor in title to hold the Expansion Land available as aforesaid, necessary for said Expansion Space, until the option for the Expansion Space has been terminated in accordance with paragraph I. of this Exhibit R or until such date which is twelve (12) months after the Term Commencement Date of this Lease, or until such expansion has been constructed, whichever is sooner. Landlord shall exercise good faith efforts to obtain, simultaneously with the approvals and permits necessary for construction of the original Building, any and all approvals and permits, including but not limited to all zoning, subdivision, wetlands and environmental permits and approvals, necessary for the construction of the Expansion Space generally similar to the footprint and site plan shown on the Expanded Building Site Plan. In the event that any of the applicable authorities require modifications to the Expanded Building Site Plan, then Landlord and Tenant hereby further agree that they will work and cooperate with each other to reach a mutual agreement on any such modifications, provided, however, that in no event shall such modifications result in the Expansion Space containing less than seventy-five thousand (75,000) rentable square feet. If, after having exercised good faith efforts, Landlord is unable to obtain all such necessary permits and approvals for the construction of the Expansion Space by the Expansion Permit Date, as defined in paragraph I. below, as it may be extended, then this Exhibit R, including paragraph I., shall be null and void and of no further force and effect, and Landlord, or its affiliate, shall no longer be required to hold the Expansion Land required for the Expansion Space for Tenant as contemplated hereunder. 120 I. EXPANSION SPACE (i) In the event that Tenant desires to exercise its option to lease and occupy the Expansion Space, and there does not then exist any uncured, continuing Event of Default hereunder, and Tenant is leasing and occupying at least one hundred percent (100%) of the Building, written notice of Tenant's intention to lease and occupy such Expansion Space (the "Expansion Notice") must be given to Landlord not later than such date which is twelve (12) months after the Term Commencement Date of this Lease (the "Expansion Exercise Date"). If Tenant elects to expand by leasing and occupying the Expansion Space (the "Lease for the Expansion Space") as herein provided, the annual Fixed Rent for the Expansion Space shall be an amount equal to the following: Years 1-5: $1,191,000.00/Year; $99,262.50/Month; $15.88/RSF Years 6-10: $1,415,250.00/Year; $117,938.00/Month; $18.87/RSF (Note: These figures reflect an adjustment for cleaning of an estimated 15,000 square feet of lab area) Notwithstanding anything to the contrary contained in this Paragraph I. of this Exhibit R, in the event that the Term of this Lease is extended beyond the initial ten (10) year Term of this Lease as a result of Tenant exercising its expansion option hereunder in conformity with the foregoing provisions, then such Term shall be extended, subject to the provisions of this Exhibit R (including the next full paragraph) for such additional period as necessary to comply with the terms of this paragraph I. (the "Additional Extension Term"). In such event, the Fixed Rent for the original Premises hereunder during the Additional Extension Term shall be $18.86 per square foot. The Lease for the Expansion Space shall be in the same form as this Lease, and, except as herein set forth, on the same terms and conditions as are set forth in this Lease and shall be for a Term of ten (10) years. The Lease for the Expansion Space shall provide for an Expansion Scheduled Term Commencement Date (Landlord and Tenant hereby agreeing that such date occur no later than twelve (12) months following the Expansion Notice by Tenant) and an Expansion Term Commencement Date, the former to be mutually agreed upon by Landlord and Tenant in good faith, but in no event less than thirty-six (36) weeks or more than forty-four (44) weeks after obtaining all required permits and approvals for construction of the Expansion Space, considering such factors as weather and material availability (it being agreed by Landlord and Tenant that such Expansion Notice by Tenant occurring between October 1 and March 1 shall add two (2) additional months to the Expansion Scheduled Term Commencement Date for such space beyond that which would otherwise be expected). The Lease for the Expansion Space shall also provide (i) for an Expansion Outside Delivery Date of sixty (60) days after the Expansion Scheduled Term Commencement Date, (ii) Tenant the right to cancel the Lease for the Expansion Space in the event that the Expansion Space is not delivered on or before the Expansion Outside Delivery Date, as extended for delays due to Force Majeure (up to an aggregate of forty-five (45) days) or Tenant's Delay as therein described, and (iii) that the Tenant's Plans for the Expansion Space prepared by and being delivered by Tenant to Landlord are attached as an Exhibit to the Lease for the Expansion Space. The proposed form of Lease for the Expansion Space shall be delivered by Landlord to Tenant promptly after such Expansion Notice to Tenant, and a mutually agreed upon form shall be executed by Landlord and Tenant within forty-five (45) days from the date of Tenant's receipt of a proposed form of Lease for the Expansion Space from Landlord in the form as herein required, 121 unless such date is extended by mutual agreement of both parties hereto. Tenant and Landlord shall use reasonable efforts, each acting in good faith, to execute the Lease for the Expansion Space within said forty-five (45) days from the date of Tenant's receipt of a proposed form from Landlord. Notwithstanding the foregoing, Landlord and Tenant agree that any such Lease for the Expansion Space may, at the sole option of Landlord, be in the form of a lease amendment to this Lease, whereupon any references herein to the Lease for the Expansion Space shall also be deemed to refer to any such amendment to this Lease, as the case may be. Landlord and Tenant hereby further agree that in the event that the parties enter into a Lease for the Expansion Space, as aforesaid, they shall enter into an amendment to this Lease evidencing an agreement to extend the initial Term of this Lease such that the expiration of the initial Term of this Lease for the original Premises hereunder and of the Lease for the Expansion Space for such additional space shall be coterminous. If not already obtained in connection with the construction of the original Building, Landlord agrees to exercise good faith efforts to obtain all necessary permits and approvals to construct the Expansion Space within twelve (12) months after receipt of the Expansion Notice (the "Expansion Permit Date"). If Tenant fails to exercise its option as to the Expansion Space, or exercises its option in a timely manner but thereafter fails to execute and deliver the Lease for the Expansion Space on or prior to the time period as hereinabove set forth in accordance with the provisions of this Exhibit R, or, if after proceeding diligently and using good faith efforts to obtain all required permits and approvals to construct such space by the Expansion Permit Date, Landlord is unable to obtain all of such permits and approvals, then, subject to the terms and provisions contained in this Exhibit R, Tenant's option as to the Expansion Space and the rights and obligations of both Landlord and Tenant under this paragraph I. shall terminate forthwith and be of no further force and effect. II. ADDITIONAL EXPANSION PROVISIONS The building quality, plans and specifications for the Expansion Space shall be in accordance with the Expanded Building Site Plan and specifications substantially comparable to the Building initially leased herein, except as hereinafter provided, which such plans and specifications shall be set forth in the Lease for the Expansion Space. Without limiting the foregoing, the building quality, fit and finish of the Expansion Space shall be substantially comparable to the Building initially leased herein based on Landlord's Plans and Tenant's Plans and specifications for the initial Building. In addition, the Expansion Space shall be landscaped to the mutual satisfaction of Landlord and Tenant, each acting reasonably. Landlord's obligation to construct the Expansion Space is contingent upon Landlord's ability, using a good faith diligent effort, (i) to finance the project cost of such Expansion Space, or such portion thereof as the Landlord elects to finance, at the annual Fixed Rent as determined in paragraph I. above, and (ii) to obtain applicable permits and approvals required under building, zoning and environmental laws, codes, rules and regulations and other laws then affecting the use and development of such land in order to construct the Expansion Space in accordance with all of the terms of this Lease. Further notwithstanding any language to the contrary contained in this Exhibit R, in the event that Tenant's option as to the Expansion Space expires or has otherwise been terminated pursuant to the above provisions of this Exhibit R, then Landlord shall have, at any time thereafter during the Term of this Lease, the right to construct the Expansion Space (or a portion thereof), and to determine whether it 122 shall be contiguous to the Building or not, adjacent to the Building or elsewhere on the Lot, and lease such space to any third party upon such terms and conditions as are negotiated by Landlord in its sole and absolute discretion and Tenant shall have no further rights thereto. Landlord and Tenant hereby further acknowledge and agree that in such event, the Expansion Space may be enlarged or reduced by Landlord, in accordance with applicable laws, codes, rules and regulations. Such Expansion Space, whether for the original contemplated square footage or greater or less than the amount as aforesaid, shall be subject to the terms and conditions set forth in the first complete paragraph of paragraph II. above (i.e. conditions as to building quality, fit and finish). In connection therewith, and in connection with any Expansion Space constructed pursuant to this Exhibit R, whether for Tenant or not, Landlord shall (i) if necessary, relocate such portion of the Building Parking Area, as designated on Exhibit A, to an area as close to the Building as reasonably possible, specifically as designated by Landlord so long as such area is within the relocation parking area shown on Exhibit A hereto (i.e. on Lots 10D and 10E), Tenant hereby agreeing that such relocation parking area described by Landlord on Exhibit A is acceptable to Tenant, (ii) have the right to temporarily access such portion of the Premises comprising a 5' area in side of the north wall on floors 1-3 of the Building, as such area is shown as cross-hatched on Exhibit A hereto, Landlord hereby agreeing to minimize any interruptions to Tenant in connection therewith, and, (iii) if such Expansion Space is not constructed for Tenant, (a) construct a demising wall between the two (2) phases shown on said Exhibit A such that the Premises hereunder (including all building systems) shall be independent of the Expansion Space, Tenant hereby acknowledging in such event loss of the window line along the north wall and (b) reduce the initial Building Parking Area by seventy-two (72) parking spaces, if necessary, in accordance with and subject to the provisions of Section 10.14 of this Lease. Subject to the foregoing provisions, Landlord and Tenant hereby further agree that they shall enter into an agreement amending, modifying or supplementing this Lease, if necessary, in order to reflect the occupancy of the Building by any such additional tenant(s) other than Tenant if the Expansion Space is constructed as so permitted by Landlord hereunder. 123 EXHIBIT S Westford Technology Park - Building 10 Preliminary Construction Schedule - 3/13/00

Such notice shall contain the proposed essential terms with respect to such rentable area (Landlord's summary thereof, shall herein be referred to as the "Offer" or "Landlord's Offer"). The Offer shall set forth all of the essential terms and conditions upon which Landlord proposes to lease such space (i.e. the annual fixed rent amounts, the operating expense base amounts, and the allowances). Upon receipt of such notice and the Offer from Landlord, and provided further that there does not then exist an uncured, continuing default under this Lease and provided further that the Tenant is then leasing (including subleasing) one hundred percent (100%) of the Premises, then Tenant shall have a right to lease any such space on the terms set forth in the Offer by giving notice to Landlord to such effect within five business (5) days after Tenant's receipt of Landlord's notice of such Offer. If such notice is not so timely given by Tenant, then Landlord shall be free to lease the subject space, or portion thereof, to any third party on the terms and conditions contained in the Offer (or on such other terms and conditions as are negotiated by Landlord in its sole discretion) at any time after the expiration of said five (5) day period. The non-exercise by Tenant of its rights under this Exhibit U as to any one Offer by Landlord shall not be deemed to waive any of Tenant's rights of first offer as to other Building(s) aforesaid. Notwithstanding any language to the contrary in this Exhibit U, Tenant's rights of first offer hereunder (i) shall be subject and subordinate to the pre-existing rights of other tenants, as such rights are set forth in Exhibit Q of this Lease (ii) shall not revive and continue should such Building become available after Tenant's waiver and subsequent leasing by Landlord, and (iii) shall apply to the leasing of the entire Building(s) specified in the Offer and not portions thereof. In the event that Tenant accepts Landlord's offer to lease such rentable space in said Building(s), which is the subject of Landlord's Offer to Tenant, then Landlord and Tenant hereby agree that they shall enter into a mutually acceptable agreement amending, modifying or supplementing this Lease, specifying that such rentable area is a part of the Premises under this Lease and demising said premises to Tenant, or at Landlord's election, shall enter into a separate lease agreement substantially in the form of this Lease, as modified to comply with the terms of the Offer, with respect to such rentable space. Such amendment (or separate lease agreement, as the case may be) shall also contain other appropriate terms and provisions relating to the addition of such rentable space to this Lease or the leasing of such rentable space, as applicable, and shall be signed by Tenant within thirty (30) days of receipt of the proposed agreement from the Landlord in the form as hereinabove required. Notwithstanding anything to the contrary in this Exhibit U, if Tenant notifies Landlord of its election to lease such rentable space in said Building(s) which was the subject of the Offer and then fails to execute and deliver the required amendment to this Lease (or separate lease agreement, as applicable) once the same has been mutually agreed upon by Landlord and Tenant in accordance with this Exhibit U, then (i) Tenant shall be deemed to have waived its rights to lease the offered space under this Exhibit U, (ii) Landlord shall have the unrestricted right to lease such space upon whatever terms and conditions as are negotiated by Landlord in its sole discretion; and (iii) Tenant's right of first offer as to rentable space in the Building hereunder shall terminate and be of no further force and effect. The recording by 5 129 the Landlord of an affidavit to such effect shall be conclusive evidence of the termination or waiver of Tenant's first offer option hereunder. Otherwise, if the Landlord and Tenant, each acting reasonably and in good faith, fail to agree on a mutually agreeable form of amendment to this Lease (or separate lease agreement, as the case may be) within said thirty (30) day period upon receipt of Landlord's proposed form of agreement, unless such date is extended by mutual agreement of both parties hereto, then such failure shall be treated as a non-exercise by Tenant of its right of first offer in accordance with the first Section of this Exhibit U and Landlord shall be free to lease the subject space, or portion thereof, to a third party as aforesaid. 6
