Lease Grant. Subject to the terms of this Lease, Landlord leases to Tenant, and Tenant leases from Landlord, real property located at 2 Omni Way, Chelmsford, Massachusetts together with all improvements located thereon including the office building located thereon containing approximately 82,228 rentable square feet (the "Premises"), as shown on the site plan attached hereto as Exhibit A. The office building located on the Premises shall hereinafter be referred to as the "Building"). The legal description of the Premises is attached hereto as Exhibit B. 2. Term. The term of this Lease shall commence on the earlier of (i) the date which is one hundred twenty (120) days after the date upon which Landlord provides to Tenant written notice of availability of the Premises or (ii) the date upon which Tenant occupies the Premises for the Permitted Use, but in no event shall such date be later than July 1, 1999 (the "Commencement Date"), and expiring on the last day of the month in which the thirteenth (13th) anniversary of the Commencement Date occurs (the "Term", which definition shall include all renewals of the initial Term). If the Premises are not delivered to Tenant on the Commencement Date, then (a) Tenant's obligation to pay Basic Rent and Additional Rent (as defined in Section 3) shall be waived until Landlord tenders possession of the Premises to Tenant, (b) Landlord shall not be in default hereunder or be liable for damages therefor, and (c) Tenant shall accept possession of the Premises when Landlord tenders possession thereof to Tenant. Use and occupancy of the Premises by Tenant prior to the Commencement Date shall be subject to all of the provisions of this Lease excepting only those requiring the payment of Basic Rent. 3. Rent. (a)......Basic Rent. "Basic Rent" (herein so called) shall be the following amounts for the following periods of time: ------------------------------------- ------------------------------------- Time Period Annual Basic Rent Monthly Basic Rent Lease Years 1-2 $657,824.00 $54,818.67 Lease Years 3-5 $945,622.00 $78,801.83 Lease Years 6-8 $986,736.00 $82,228.00 Lease Years 9-13 $1,068,964.00 $89,080.33 33 The term "Lease Year" shall mean any period of twelve (12) months commencing on the first day of the first full month of the Term or any anniversary of such date or, if fewer than twelve (12) months remain in the Term after any such anniversary period, commencing on such anniversary date through the last day of the Term. (b)......Payment. Tenant shall timely pay to Landlord Basic Rent and all additional sums to be paid by Tenant to Landlord under this Lease (collectively, the "Rent"), without notice, deduction or set off, except as otherwise provided herein, at Landlord's address provided for in this Lease or as otherwise specified by Landlord. Basic Rent, adjusted as herein provided, shall be payable monthly in advance, and shall be accompanied by all applicable state and local sales or use taxes. Basic Rent shall be payable on the first day of each month beginning on the first day of the first full calendar month of the Term. The monthly Basic Rent for any partial month at the beginning of the Term shall equal the product of 1/365 of the annual Basic Rent in effect during the partial month and the number of days in the partial month from and after the Commencement Date, and shall be due on the Commencement Date. (c)......Operating Costs. (1)......Tenant shall pay, as "Additional Rent", the Operating Costs (defined below). Landlord may make a good faith estimate of the Additional Rent to be due by Tenant for any calendar year or part thereof during the Term, and Tenant shall pay to Landlord, on the Commencement Date and on the first day of each calendar month thereafter, an amount equal to the estimated Additional Rent for such calendar year or part thereof divided by the number of months therein. From time to time, but not more often than twice in any twelve (12) month period, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant and deliver a detailed line item copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimations so that, by the end of the calendar year in question, Tenant shall have paid all of the Additional Rent as estimated by Landlord. Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Operating Costs are available for each calendar year. (2)......The term "Operating Costs" shall mean all expenses and disbursements (subject to the limitations set forth below) that Landlord incurs in connection with the ownership, operation, and maintenance of the Premises, determined in accordance with generally accepted accounting principles ("GAAP") consistently applied, including, but not limited to, the following costs: (A) wages and salaries (including management fees) of all employees engaged in the operation, maintenance, and security of the Premises, including taxes, insurance and benefits relating thereto; (B) all supplies and materials used in the operation, maintenance, repair, replacement, and security of the Premises; (C) costs for improvements made to the Premises which, if capital in nature, shall be amortized over the useful economic life of such improvements as determined by Landlord in its reasonable discretion; (D) cost of all utilities, except the cost of utilities paid directly by Tenant or reimbursable to Landlord by Tenant other than pursuant to a provision similar to this Section 3.(c); (E) insurance expenses; (F) repairs, replacements, and general maintenance of the Premises; and (G) service or maintenance contracts with independent contractors for the operation, maintenance, repair, replacement, or security of the Premises (including, without limitation, alarm service, window cleaning, and elevator maintenance). Operating Costs shall not include costs for (i) repair, replacements and general maintenance paid by proceeds of insurance or by Tenant or other third parties; (ii) interest, amortization or other payments on loans to Landlord; (iii) depreciation; (iv) leasing commissions; (v) legal expenses for services, other than those that benefit Tenant (e.g., tax disputes); (vi) Taxes (defined below); (vii) federal income taxes imposed on or measured by the income of Landlord from the operation of the Premises; (viii) any cost or expense to the extent to which Landlord is paid or reimbursed (other than as a payment for Operating Costs), including but not necessarily limited to, (1) work or service performed for any tenant (including Tenant) at such tenant's costs, (2) the cost of any item for which Landlord is paid or reimbursed by insurance warranties, service contracts, condemnation proceeds or otherwise, (3) charges (including applicable taxes) for electricity, water and other utilities for which Landlord is entitled to reimbursement pursuant to other provisions of this Lease, and (4) the cost of any HVAC, janitorial or other services provided to tenants on an extra-cost basis after regular business hours as defined in the Lease; (ix) the cost of correcting initial defects in the design, construction or equipment of the Building; (x) salaries and bonuses of officers and executives of Landlord; (xi) any cost included in Operating Costs representing an amount paid to a person, firm, corporation or other entity related to Landlord which is in excess of the amount which would have been paid on an arms length basis in the absence of such relationship; (xii) any capital cost necessary to cure any violation of any law, ordinance or regulation applicable to the Building existing as of the Commencement Date or to remediate any environmental condition (existing as of the date of the Lease) provided Tenant in no way exacerbates any such condition; (xiii) the cost of acquiring sculptures, paintings and other objects of art in excess of $2,000 per item; and (xiv) the cost of advertising or promotion for the Building. (3)......Tenant shall also pay the Taxes for each year and partial year falling within the Term, in the same manner as provided above for Additional Rent with regard to Operating Costs. "Taxes" shall mean taxes, assessments, and governmental charges whether federal, state, county or municipal, and whether they be by taxing districts or authorities presently taxing or by others, subsequently created or otherwise, and any other taxes and assessments attributable to the Building (or its operation), excluding, however, penalties and interest thereon and federal and state taxes on income (if the present method of taxation changes so that in lieu of the whole or any part of any Taxes, there is levied on Landlord a capital tax directly on the rents received therefrom or a franchise tax, assessment, or charge based, in whole or in part, upon such rents for the Building, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be included within the term "Taxes" for purposes hereof). Tenant shall, at its sole cost and expense and upon prior written notice to Landlord, have the right to seek an abatement of the Taxes provided that Tenant shall promptly provide Landlord with copies of all papers filed with various authorities in connection with seeking such an abatement and with copies of all papers received from other parties relating to any such abatement. Taxes shall include the costs of consultants retained in an effort to lower taxes and all costs incurred in disputing any taxes or in seeking to lower the tax valuation of the Building. The following items shall be excluded from Taxes: (A) inheritance taxes; (B) gift taxes; (C) transfer taxes; (D) franchise taxes; (E) excise taxes; (F) income taxes; (G) profit taxes; and (H) late payment charges and penalties provided Tenant is not in default of any of its payment obligations under this Lease. Subject to the provisions of the next succeeding sentence, any real estate related betterment assessments shall be payable over the longest period of time permitted by law. If Landlord elects to pay any such assessments over a shorter period of time, Tenant shall only be required to pay during any given period of time that portion of any given assessment that would have been required to be paid during such period of time if such assessment had been paid over the longest period of time permitted by law. (4)......By April 1 of each calendar year, or as soon thereafter as practicable, Landlord shall furnish to Tenant a statement of Operating Costs for the previous year, adjusted as provided in Section 3.(c)(6), and of the Taxes for the previous year (the "Operating Costs and Tax Statement"). If the Operating Costs and Tax Statement reveals that Tenant paid more for Operating Costs than the actual amount for the year for which such statement was prepared, or more than its actual share of Taxes for such year, then Landlord shall promptly credit or reimburse Tenant for such excess; likewise, if Tenant paid less than the actual Additional Rent or Taxes due, then Tenant shall promptly pay Landlord such deficiency within thirty (30) days after receiving written notice from Landlord of the amount of such deficiency. Any such Operating Costs and Tax Statement furnished by Landlord shall be binding and conclusive upon Tenant unless Tenant shall notify Landlord that Tenant disputes the correctness of such Operating Costs and Tax Statement within one hundred eighty (180) days after the submission thereof by Landlord. If Tenant disputes such Operating Cost and Tax Statement as aforesaid, and Tenant is not in default of its monetary obligations under this Lease, Tenant shall have the right to audit Landlord's books used to determine said Operating Cost and Tax Statement within one hundred eighty (180) days after submission thereof by Landlord, which right Tenant agrees not to exercise more than once annually. Access to said Operating Cost and Tax Statement books shall be provided within thirty (30) days of Tenant's request. Any information obtained by Tenant pursuant to the provisions of this Section 3(d)(4) shall be treated as confidential. If any such audit discloses Tenant paid in excess of Tenant's proportionate share of Operating Costs or Tax Escalation, Landlord shall promptly reimburse such excess to Tenant within thirty (30) days after Tenant's demand therefor. Landlord shall maintain its books used to determine the Operating Cost and Tax Statement in a manner consistent with reputable professional standards used to maintain the books of comparable properties. 4. Delinquent Payment; Handling Charges. All payments past due by five (5) days beyond the due date required of Tenant hereunder shall bear interest from the fifth (5th) day beyond the date due until paid at the lesser of 18% per annum (the "Interest Rate") or the maximum lawful rate of interest. In no event, however, shall the charges permitted under this Section 4 or elsewhere in this Lease, to the extent they are considered to be interest under law, exceed the maximum lawful rate of interest. 5. Security Deposit. Contemporaneously with the execution of this Lease, Tenant shall pay to Landlord $160,000.00 (the "Security Deposit"), which shall be held by Landlord to secure Tenant's performance of its obligations under this Lease. The Security Deposit is not an advance payment of Rent or a measure or limit of Landlord's damages upon an Event of Default (defined in Section 16). Landlord may, from time to time and without prejudice to any other remedy, use all or a part of the Security Deposit to perform any obligation Tenant fails to perform hereunder. Following any such application of the Security Deposit, Tenant shall pay to Landlord on demand the amount so applied in order to restore the Security Deposit to its original amount. Provided that Tenant has performed all of its obligations hereunder, Landlord shall, within thirty (30) days after the Term ends, return to Tenant the portion of the Security Deposit which was not applied to satisfy Tenant's obligations. The Security deposit may be commingled with other funds, and no interest shall be paid thereon. If Landlord transfers its interest in the Premises and the transferee assumes Landlord's obligations under this Lease, then Landlord may assign the Security Deposit to the transferee and Landlord thereafter shall have no further liability for the return of the Security Deposit. In lieu of a cash Security Deposit, simultaneously with the execution and delivery of this Lease, Tenant may deliver to Landlord an irrevocable and unconditional standby letter of credit made payable to Landlord, its successors and assigns, in the sum of $160,000.00 (the "Letter of Credit"), substantially in the form of the sample letter of credit attached hereto as Exhibit F or in such other form as is reasonably acceptable to Landlord, which shall secure the performance by Tenant of all obligations on the part of Tenant hereunder. The issuer of the Letter of Credit shall be a banking institution with at least a rating of A and otherwise reasonably acceptable to Landlord. Although Landlord shall only have the right to draw under the Letter of Credit as set forth herein, under the terms of the Letter of Credit, the sole condition to Landlord's draw upon the Letter of Credit shall be presentment to the issuer thereof, prior to or on the expiration date, of a demand for payment. The Letter of Credit shall be self-renewing from year to year during the Term of this Lease so as to expire no earlier than thirty (30) days following the Lease expiration date and shall contain such other customary terms as Landlord requires in its reasonable discretion. It is agreed: (i) that the Letter of Credit may be drawn upon to cure any Event of Default that may exist, without prejudice to any other remedy or remedies which Landlord may have on account thereof, and upon Landlord's demand, Tenant shall reimburse the issuer for the amount so drawn so that the Letter of Credit will be restored to its original amount; (ii) subject to the provisions of clause (iv) below, that the Letter of Credit may be drawn upon if the Letter of Credit has not been extended or renewed without amendment at least forty-five (45) days prior to any then-current expiration date thereof; (iii) that if the rating of the issuer of the Letter of Credit at any time drops below A, then, within sixty (60) days of Landlord's demand, Tenant shall replace the Letter of Credit with another Letter of Credit in a form reasonably acceptable to Landlord and with an issuer with a rating of at least an A and otherwise reasonably acceptable to Landlord; Landlord may draw on the existing Letter of Credit if, after Landlord requests that Tenant replace the Letter of Credit as aforesaid, Landlord is not provided with a substitute Letter of Credit in a form, and from an issuer, satisfactory to Landlord as provided above at least fifteen (15) days prior to the then-current expiration date of the Letter of Credit; (iv) if at any time, but in any event, at least sixty (60) days prior to the expiration of the Letter of Credit, Tenant may seek Landlord's consent to switch issuers of the Letter of Credit provided the prospective issuer has a rating of at least an A and is otherwise reasonably acceptable to Landlord and the new form of Letter of Credit satisfies the requirements of Landlord hereunder and is otherwise reasonably acceptable to Landlord; Landlord may draw on the existing Letter of Credit if, after Tenant requests Landlord's consent to switch issuers as aforesaid, Landlord is not provided with a substitute Letter of Credit in a form, and from an issuer, satisfactory to Landlord in its sole and absolute discretion at least forty-five (45) days prior to the then-current expiration date of the Letter of Credit; (v) that should the Premises be conveyed by Landlord, the Letter of Credit or any portion thereof shall be assigned to Landlord's grantee, and if the same be assigned as aforesaid, Tenant hereby releases Landlord from any and all liability with respect to the Letter of Credit and its application or return, and Tenant agrees to look to such grantee for such application or return, provided such grantee assumes Landlord's obligations under this Lease (including this Section 5); and (vi) that the Letter of Credit shall be returned to Tenant upon the later of (a) thirty (30) days after the expiration of the Term or any renewal or extension thereof, or (b) the date Tenant has vacated the Premises and surrendered possession thereof to Landlord at the expiration of the Term or any extension thereof as provided herein and has paid Landlord all sums due and owing under this Lease. If Tenant initially provides Landlord with a cash Security Deposit, Tenant may replace such cash Security Deposit with a Letter of Credit in accordance with the provisions of the preceding paragraph. Upon Landlord's receipt of a Letter of Credit satisfying the terms and conditions of the preceding paragraph, Landlord shall promptly return the cash Security Deposit to Tenant. For the purposes of this Section 5, a rating of at least A (or its equivalent) shall mean that such issuer has a rating of at least A (or its equivalent) from two (2) of the following four (4) rating agencies: Fitch Investors Service, Moody's Investor Service, Standard & Poor's Corporation and Duff & Phelps. 6. Landlord's Obligations. (a)......Services. Landlord shall furnish to Tenant the following services (the cost of which services shall be considered Operating Costs): (1) hot and cold water at bathroom sinks provided for general use of tenants of the Building; (2) heated and refrigerated air conditioning as appropriate, at such temperatures and in such amounts as are standard for comparable buildings in the vicinity of the Building; (3) janitorial service (which janitorial service shall include service to the interior and exterior of the Building and the Premises and shall include the services customarily provided to comparable properties by reputable professional management companies, including, without limitation, maintenance, repairs and replacement of (u) the parking area associated with the Building and located on the Premises, (v) all grass, shrubbery and other landscape treatments on the Premises, (w) the exterior of the Building (including painting), (x) sprinkler systems and sewage lines, and (y) any other maintenance, repair or replacement items normally associated with the foregoing) to the Premises on weekdays, other than the holidays enumerated on Exhibit I attached hereto (collectively, "Building Holidays"), for Building-standard installations and such window washing as may from time to time be reasonably required but not less than twice a year; (4) elevators for ingress and egress to the floors of the Building, provided that Landlord may reasonably limit the number of operating elevators during non-business hours and holidays; and (5) electrical current during normal business hours for equipment that does not require more than 110 volts and whose electrical energy consumption does not exceed normal office usage. While Tenant is the sole occupant of the Building, Tenant may, with Landlord's prior written consent (which consent shall not be unreasonably withheld or delayed), substitute at Tenant's expense any of the providers of the services described in this Section 6.(a) with reputable, licensed third party service providers located in the area in which the Building is located; provided, however, Tenant shall provide Landlord with copies of all contracts with any such service provider and said contracts shall be in form and substance reasonably satisfactory to Landlord. If, in accordance with the provisions of the preceding sentence, Tenant engages (at its own cost) providers for all of the services to be provided by Landlord under this Section 6.(a), the management fee included in Operating Costs shall be reduced to the greater of (i) $1,300.00 per month or (ii) one and one-quarter percent (1 1/4%) of the gross revenues derived by Landlord from the Premises. If Tenant engages providers of the services set forth in this Section 6.(a) as aforesaid and any such services are provided, in Landlord's reasonable discretion, at an unsatisfactory level as would customarily be provided to comparable buildings, Landlord may, upon prior written notice to Tenant, elect to provide such services and the management fee shall no longer be reduced. If Landlord is providing the services set forth in this Section 6.(a) and Tenant desires any of the services specified in Section 6.(a)(2): (A) at any time other than between 8:00 a.m. and 6:00 p.m. on weekdays (excluding Building Holidays), or (B) on Saturday, Sunday or Building Holidays, then such services shall be supplied to Tenant upon the written request of Tenant delivered to Landlord before 3:00 p.m. on the business day preceding such extra usage, and Tenant shall pay to Landlord the cost of such services within ten (10) days after Landlord has delivered to Tenant an invoice therefor. The costs incurred by Landlord in providing after-hour HVAC service to Tenant shall include costs for electricity, water, sewage, water treatment, labor, metering, filtering, and maintenance reasonably allocated by Landlord to providing such service. Landlord and Tenant hereby acknowledge and agree that, as of the Commencement Date, Tenant shall engage providers of the services set forth in this Section 6.(a). However, upon sixty (60) days prior written notice to Landlord, Tenant may elect to have Landlord provide such services. If, during the last two (2) years of the Term (inclusive of the five-year extension if Tenant elects to exercise the same in accordance with the provisions of Exhibit G) and during a time when Tenant is engaging providers of the services set forth in this Section 6.(a), Tenant elects to make a capital improvement to the Base Building (as hereinafter defined) because that portion of the Base Building fails to operate (as opposed to operates less efficiently), Landlord agrees to pay the unamortized cost of any such capital improvement on the following terms and conditions provided such failure is not a result of any act, omission, fault, negligence or neglect of Tenant, its agents, employees, invitees or contractors: (i) Landlord and Tenant agree in writing on the cost of any such capital improvement and the useful life over which any such capital improvement shall be amortized prior to the installation of any such capital improvement (ii) to the extent capital improvements are devoted to Building systems, the Building systems shall not be in excess of standard building design for comparable buildings in the 495 North market; and (iii) Landlord agrees to pay the unamortized cost of any such capital improvement as previously agreed to in writing by the parties within sixty (60) days after the later of the expiration of this Lease or the date Tenant surrenders the Premises in accordance with this Lease provided Tenant is not in default hereunder, this Lease does not terminate prior to the stated expiration date and Tenant has maintained and repaired any such capital improvement in accordance with the provisions of this Lease. For the purposes of this Lease, the "Base Building" shall mean the roof, foundation, structural columns and Building systems to the extent any of the foregoing have not been altered or improved by Tenant in any manner. (b)......Landlord's Maintenance Obligations. This Lease is intended to be a net lease; accordingly, Landlord's maintenance obligations are limited to the repair, maintenance and replacement of the Building's roof and the repair, maintenance and replacement of the foundation and structural members of exterior walls (the "Building's Structure"); Landlord shall not be responsible for (1) any such work until Tenant notifies Landlord of the need therefor in writing, (2) for alterations to the Building's Structure required by applicable law because of Tenant's use of the Premises (which alterations shall be Tenant's responsibility), (3) any such work caused by Tenant's negligence or its failure to comply with the provisions of this Lease, or (4) any costs incurred by Landlord in connection with the repair and maintenance of the roof, which repair and maintenance costs shall be considered an Operating Cost and paid by Tenant in accordance with Section 3 above. The Building's Structure does not include skylights, windows, glass or plate glass, doors, special fronts, or office entries, all which shall be maintained by Tenant. Landlord's liability for any defects, repairs, replacements or maintenance for which Landlord specifically is responsible for under this Lease shall be limited to the cost of performing the work. (c)......Excess Utility Use. Landlord shall not be required to furnish electrical current for equipment that requires more than the electrical capacity currently provided in the Building (the "Base Building Electrical Capacity"). If Tenant's requirements for or consumption of electricity exceed the Base Building Electrical Capacity, Landlord shall, at Tenant's expense, make reasonable efforts to supply such service through the then-existing feeders and risers serving the Building, and Tenant shall pay to Landlord the cost of such service within ten (10) days after Landlord has delivered to Tenant an invoice therefor. Landlord may determine the amount of such additional consumption and potential consumption by any verifiable method, including installation of a separate meter in the Premises installed, maintained, and read by Landlord, at Tenant's expense. Tenant shall not install any electrical equipment requiring special wiring or requiring voltage in excess of the Base Building Electrical Capacity unless approved in advance by Landlord. The use of electricity in the Premises shall not exceed the capacity of existing feeders and risers to or wiring in the Building. Any risers or wiring required to meet Tenant's excess electrical requirements shall, upon Tenant's written request, be installed by Landlord, at Tenant's cost, if, in Landlord's judgment, the same are necessary and shall not cause permanent damage to the Building or the Premises, cause or create a dangerous or hazardous condition, entail excessive or unreasonable alterations, repairs, or expenses, or interfere with or disturb other tenants of the Building. If Tenant uses machines or equipment in the Building which affect the temperature otherwise maintained by the air conditioning system or otherwise overload any utility, Landlord may install supplemental air conditioning units or other supplemental equipment in the Building, and the cost thereof, including the cost of installation, operation, use, and maintenance, shall be paid by Tenant to Landlord within ten (10) days after Landlord has delivered to Tenant an invoice therefor. (d)......Restoration of Services; Abatement. Landlord shall use reasonable efforts to restore any service required of it that becomes unavailable; however, such unavailability shall not render Landlord liable for any damages caused thereby, be a constructive eviction of Tenant, constitute a breach of any implied warranty, or, except as provided in the next sentence, entitle Tenant to any abatement of Tenant's obligations hereunder. If, however, Tenant is prevented from using the Premises for ten (10) consecutive business days because of the unavailability of any such service, then Tenant shall, as its exclusive remedy be entitled to a reasonable abatement of Rent for each consecutive day (after such ten (10) day period) that Tenant is so prevented from using the Premises. (e)......Taxes. Provided Tenant is not in default of any of its monetary obligations under this Lease, Landlord shall pay promptly when due to the taxing authority having jurisdiction all taxes, rates, duties, levies and assessments whatsoever, whether municipal, state, Federal or otherwise, levied, imposed or assessed against the Building or upon Landlord in respect thereof or from time to time levied, imposed or assessed in the future in lieu thereof, including those levied, imposed or assessed for education, schools and local improvements. (f)......Landlord's Insurance. Landlord shall carry throughout the Term of this Lease fire and extended coverage --------------------- insurance on the Building for the full replacement value. 7. Improvements; Alterations; Repairs; Maintenance. (a)......Improvements; Alterations. Improvements to the Premises shall be installed at Tenant's expense only in accordance with plans and specifications which have been previously submitted to and approved in writing by Landlord. No alterations or physical additions in or to the Premises may be made without Landlord's prior written consent, which shall not be unreasonably withheld or delayed; however, Landlord may withhold its consent to any alteration or addition that would affect the Building's structure or its HVAC, plumbing, electrical, or mechanical systems. Notwithstanding the foregoing, Tenant may from time to time make alterations, additions or improvements to the Premises, without the consent of Landlord and without Landlord's approval of plans, provided: (i) the cost thereof shall not exceed Fifty Thousand Dollars ($50,000.00) in the aggregate in any consecutive twelve-month period; (ii) Tenant shall, prior to commencing any such alterations, additions and/or improvements in the Premises in connection therewith, furnish Landlord with a complete set of plans and specifications for any such alterations, additions and/or improvements; (iii) such alterations, additions and/or improvements shall not involve or affect the exterior or the structure of the Building or any of the mechanical, electrical or plumbing systems of the Building; and (iv) Tenant shall comply with all requirements of this Lease with respect to such alterations, additions and/or improvements other than obtaining the prior approval of Landlord. Tenant shall not paint or install lighting or decorations, signs, window or door lettering, or advertising media of any type on or about the Premises which might affect the appearance of the exterior of the Building or any other portion of the Premises other than the interior of the Building without the prior written consent of Landlord, which shall not be unreasonably withheld or delayed; however, Landlord may withhold its consent to any such painting or installation which would affect the appearance of the exterior of the Building or of any common areas of the Building. All alterations, additions, or improvements made in or upon the Premises shall be removed by Tenant prior to the end of the Term (and Tenant shall repair all damage caused thereby) if Landlord conditioned its consent to the initial installation of any such alterations, additions or improvements upon such removal; otherwise, in the absence of such a removal condition with respect to each and every alteration, addition or improvement, all such alterations, additions or improvements (excluding moveable partitions) shall remain on the Premises at the end of the Term without compensation to Tenant. All alterations, additions, and improvements shall be constructed, maintained, and used by Tenant, at its risk and expense, in accordance with all Laws; Landlord's approval of the plans and specifications therefor shall not be a representation by Landlord that such alterations, additions, or improvements comply with any Law. (b)......Repairs; Maintenance. Tenant shall maintain the Premises in a clean safe, and operable condition consistent with the operation of a first class office building, and shall not permit or allow to remain any waste or damage to any portion of the Premises. If Tenant elects to engage providers for all services in accordance with Section 6.(a) above, Tenant shall enter into preventative maintenance/service contract(s) with maintenance contractor(s) approved by Landlord for servicing the landscaping of the Premises and all air conditioning, heating and ventilating equipment, elevators and other equipment located within or serving the Premises. All preventative maintenance/service contracts shall be in form and substance reasonably satisfactory to Landlord and shall provide that the maintenance contractor shall provide Landlord with quarterly reports respecting the maintenance of the subject equipment. Tenant shall provide Landlord with copies of all such preventative maintenance/service contracts maintained by Tenant. Irrespective of whether or not Tenant elects not to engage providers for all services in accordance with Section 6.(a) above, Tenant shall repair or replace, subject to Landlord's reasonable direction and supervision, any improvement or system installed by Tenant within the Premises and any damage to the Building caused by Tenant, Tenant's transferees, or their respective agents, contractors, or invitees. If Tenant fails to make such repairs or replacements within thirty (30) days (or such shorter period of time required to prevent any damage from occurring to the Premises) after the occurrence of such damage, then Landlord may make the same at Tenant's cost. (c)......Performance of Work. All work described in this Section 7 shall be performed only by Landlord or by contractors and subcontractors reasonably approved in writing by Landlord and Tenant. Tenant shall cause all contractors and subcontractors to procure and maintain insurance coverage naming Landlord as an additional insured against such risks, in such amounts, and with such companies as Landlord may reasonably require. All such work shall be performed in accordance with all Laws and in a good and workmanlike manner so as not to damage the Premises, the Building, or the components thereof. Tenant shall provide the names, addresses and copies of contracts for all contractors, and upon completion of any work shall promptly furnish Landlord with full and final waivers of lien covering all labors and materials included in the work in question. (d)......Mechanic's Liens. Tenant shall not permit any mechanic's liens to be filed against the Premises or the Building for any work performed, materials furnished, or obligation incurred by or at the request of Tenant. If such a lien is filed, then Tenant shall, within ten (10) days after Landlord has delivered notice of the filing thereof to Tenant, either pay the amount of the lien or diligently contest such lien and deliver to Landlord a bond or other security reasonably satisfactory to Landlord. If Tenant fails to timely take either such action, then Landlord may pay the lien claim, and any amounts so paid, including expenses and interest, shall be paid by Tenant to Landlord within ten days after Landlord has invoiced Tenant therefor. (e)......Utilities. Tenant shall obtain and pay for all water, gas, electricity, heat, telephone, sewer, sprinkler charges and other utilities and services used at the Premises, together with all taxes, penalties, surcharges, and maintenance charges pertaining thereto. Landlord shall not be liable for any interruption or failure of utility service to the Premises unless caused by Landlord's gross negligence. To the extent Tenant is not billed directly for any such utilities, any amounts payable by Tenant under this Section shall be due within ten (10) days after Landlord has invoiced Tenant therefor. (f)......Floor Load; Heavy Machinery. (i) Tenant shall not place a load upon any floor in the Building exceeding the floor load per square foot of area which such floor was designed to carry or which is allowed by law. Landlord reserves the right to prescribe the weight and position of all business machines and mechanical equipment, including safes, which shall be placed so as to distribute the weight. Business machines and mechanical equipment shall be placed and maintained by Tenant at Tenant's expense in settings sufficient, in Landlord's judgment, to absorb and prevent vibration, noise and annoyance. Tenant shall not move any safe, heavy machinery and/or heavy equipment into or out of the Building without Landlord's prior consent, which consent may include a requirement to provide insurance, naming Landlord as an insured, in such amounts as Landlord may deem reasonable. (ii).....If such safe, machinery, equipment, freight, bulky matter or fixtures requires special handling, Tenant agrees that all work in connection therewith shall comply with applicable laws and regulations. Any such moving shall be at the sole risk and hazard of Tenant, and Tenant will exonerate, indemnify and save Landlord harmless against and from any liability, loss, injury, claim or suit resulting directly or indirectly from such moving. 8. Use. Tenant shall continuously occupy and use the Premises only for general office, research and development, manufacturing, training, sales, service and engineering use (the "Permitted Use"), provided the Permitted Use complies with all applicable laws, and shall comply with all Laws relating to the use, condition, access to, and occupancy of the Premises. The Premises shall not be used for any use which is disreputable, creates extraordinary fire hazards, or results in an increased rate of insurance on the Premises, the Building or its contents, or for the storage of any hazardous materials or substances. If, because of a Tenant Party's acts, the rate of insurance on the Building or its contents increases, then such acts shall be an Event of Default, Tenant shall pay to Landlord the amount of such increase on demand, and acceptance of such payment shall not waive any of Landlord's other rights. Tenant shall conduct its business and control each other Tenant Party so as not to create any nuisance or unreasonably interfere with Landlord in its management of the Building. 9. Assignment and Subletting. (a)......Transfers; Consent. Tenant shall not, without the prior written consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (2) permit any other entity to become Tenant hereunder by merger, consolidation, or other reorganization, (3) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as to result in a change in the current control of Tenant, (4) sublet any portion of the Premises, (5) grant any license, concession, or other right of occupancy of any portion of the Premises, or (6) permit the use of the Premises by any parties other than Tenant (any of the events listed in Section 9.(a)(1) through 9.(a)(6) being a "Transfer"). If Tenant requests Landlord's consent to a Transfer, then Tenant shall provide Landlord with a written description of all terms and conditions of the proposed Transfer, copies of the proposed documentation, and the following information about the proposed transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and general references sufficient to enable Landlord to determine the proposed transferee's creditworthiness and character. Landlord shall not unreasonably withhold or delay its consent to any assignment or subletting of the Premises, provided that the proposed transferee (A) is creditworthy, (B) has a good reputation in the business community, and (C) is not a person or entity with whom Landlord is negotiating to lease space in an Affiliated Building; otherwise, Landlord may withhold its consent in its sole discretion. Concurrently with Tenant's notice of any request for consent to a Transfer, Tenant shall pay to Landlord a fee of $500.00 to defray Landlord's expenses in reviewing such request, and Tenant shall also reimburse Landlord immediately upon request for its reasonable attorneys' fees incurred in connection with considering any request for consent to a Transfer. If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes Tenant's obligations hereunder; however, any transferee of less than all of the space in the Premises shall be liable only for obligations under this Lease that are properly allocable to the space subject to the Transfer for the period of the Transfer. No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable therefor. Landlord's consent to any Transfer shall not waive Landlord's rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord, in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Rent. Tenant authorizes its transferees to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so. Tenant shall pay for the cost of any demising walls or other improvements necessitated by a proposed subletting or assignment. Notwithstanding any provisions of this Section 9(a) to the contrary, Tenant may assign or sublet, without Landlord's prior written consent, to any entity into or with which Tenant is merged or consolidated or to which all or substantially all of Tenant's assets are transferred or to any entity which controls or is controlled by Tenant or is under common control with Tenant ("Affiliate of Tenant"), provided that (i) the assignee agrees directly with Landlord, by written instrument in form satisfactory to Landlord, to be bound by all obligations of Tenant hereunder, including, without limitation, the covenant against further Transfer, (ii) Tenant provides Landlord with notice of and information (reasonably satisfactory to Landlord) regarding any such Affiliate of Tenant and such assignment to such Affiliate of Tenant before the effective date thereof, (iii) Tenant shall remain fully liable for all obligations of Tenant hereunder, and (iv) the Affiliate of Tenant has a net worth equal to or greater than the greater of (A) ninety-five percent (95%) of Tenant's net worth as of the date hereof or (B) ninety-five percent (95%) of Tenant's net worth at the time of the Transfer. (b)......Cancellation. Landlord may, within thirty (30) days after submission of Tenant's written request for Landlord's consent to an assignment or subletting (except for an assignment or sublease to an Affiliate of Tenant), cancel this Lease as to the portion of the Premises proposed to be sublet or assigned as of the date the proposed Transfer is to be effective, unless, and subject to the provisions of the succeeding sentence, Tenant withdraws its request for Landlord's consent within ten (10) days after Landlord's notice to Tenant of Landlord's cancellation of this Lease as to a portion of such Premises. Tenant shall only have the right to withdraw its request for Landlord's consent if it pertains to a sublease of a portion of the Building or a sublease of the Premises for less than the remainder of the Term. If Landlord cancels this Lease as to any portion of the Premises (assuming Tenant does not withdraw its request as aforesaid), then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant. (c)......Additional Compensation. Tenant shall pay to Landlord, immediately upon receipt thereof, the excess of (1) all compensation received by Tenant for a Transfer less the costs reasonably incurred by Tenant with unaffiliated third parties in connection with such Transfer (i.e., brokerage commissions, tenant finish work, and the like) over (2) the Rent allocable to the portion of the Premises covered thereby. 10. Insurance; Waivers; Subrogation; Indemnity. (a)......Insurance. Tenant shall maintain throughout the Term the following insurance policies: (1) commercial general liability insurance in amounts of $5,000,000 per occurrence or such other amounts as Landlord may from time to time reasonably require, insuring Tenant, Landlord, Landlord's agents and their respective affiliates against all liability for injury to or death of a person or persons or damage to property arising from the use and occupancy of the Premises, (2) insurance covering the full value of Tenant's property and improvements, and other property (including property of others) in the Premises, (3) contractual liability insurance sufficient to cover Tenant's indemnity obligations hereunder, (4) worker's compensation insurance, and (5) business interruption insurance. Tenant's insurance shall provide primary coverage to Landlord when any policy issued to Landlord provides duplicate or similar coverage, and in such circumstance Landlord's policy will be excess over Tenant's policy. Tenant shall furnish to Landlord certificates of such insurance and such other evidence satisfactory to Landlord of the maintenance of all insurance coverages required hereunder, and Tenant shall obtain a written obligation on the part of each insurance company to notify Landlord at least thirty (30) days before cancellation or a material change of any such insurance policies. All such insurance policies shall be in form, and issued by companies, reasonably satisfactory to Landlord. (b)......Waiver of Negligence; No Subrogation. Landlord and Tenant each waives any claim it might have against the other for any injury to or death of any person or persons or damage to or theft, destruction, loss, or loss of use of any property (a "Loss"), to the extent the same is insured against under any insurance policy that covers the Building, the Premises, Landlord's or Tenant's fixtures, personal property, leasehold improvements, or business, or, in the case of Tenant's waiver, is required to be insured against under the terms hereof, regardless of whether the negligence of the other party caused such Loss; however, Landlord's waiver shall not include any deductible amounts on insurance policies carried by Landlord. Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier's rights of recovery under subrogation or otherwise against the other party. (c)......Indemnity. Subject to Section 10.(b), Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages, and expenses (including attorneys' fees) arising from (1) any Loss arising from any occurrence on the Premises (other than any Loss arising out of a breach of Tenant's obligations under Section 24.(u), which shall be subject to the indemnity in such section) or (2) Tenant's failure to perform its obligations under this Lease, unless caused solely by the negligence or fault of Landlord or its agents. This indemnity provision shall survive termination or expiration of this Lease. If any proceeding is filed for which indemnity is required hereunder, Tenant agrees, upon request therefor, to defend the indemnified party in such proceeding at its sole cost utilizing counsel satisfactory to the indemnified party. (d)......Landlord's Indemnity. Subject to Section 10(b), Landlord shall defend, indemnify, and hold harmless Tenant from and against all claims, demands, liabilities, causes of action, suits, judgments and expenses (including attorneys' fees) for any Loss arising from any occurrence at the Premises caused or materially contributed to by Landlord's gross negligence in acting or failing to act, and which Loss was not contributed to in any way by Tenant's actions or omissions. This indemnity shall survive the expiration or termination of this Lease. 11. Subordination; Attornment; Notice to Landlord's Mortgagee. (a)......Subordination. This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument, or any ground lease, master lease, or primary lease (any such security instrument or lease, a "Mortgage"), that now or hereafter covers all or any part of the Premises (the mortgagee under any such mortgage or the lessor under any such lease is referred to herein as a "Landlord's Mortgagee"). Any Landlord's Mortgagee may elect, at any time, unilaterally, to make this Lease superior to its mortgage, ground lease, or other interest in the Premises by so notifying Tenant in writing. Tenant shall execute agreements confirming the subordination or superiority of this Lease to any Mortgage upon Landlord or Landlord's Mortgagee's reasonable request. (b)......Attornment. Tenant shall attorn to any party succeeding to Landlord's interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon such party's request, and shall execute such agreements confirming such attornment as such party may reasonably request. (c)......Notice to Landlord's Mortgagee. Tenant shall not seek to enforce any remedy it may have for any default on the part of Landlord without first giving written notice by certified mail, return receipt requested, specifying the default in reasonable detail, to any Landlord's Mortgagee whose address has been given to Tenant, and affording such Landlord's Mortgagee a reasonable opportunity to perform Landlord's obligations hereunder. (d)......Landlord's Mortgagee's Protection Provisions. If Landlord's Mortgagee shall succeed to the interest of Landlord under this Lease, Landlord's Mortgagee shall not be: (1) liable for any act or omission of any prior lessor (including Landlord); (2) bound by any rent or additional rent or advance rent which Tenant might have paid for more than the current month to any prior lessor (including Landlord), and all such rent shall remain due and owing, notwithstanding such advance payment; (3) bound by any security or advance rental deposit made by Tenant which is not delivered or paid over to Landlord's Mortgagee and with respect to which Tenant shall look solely to Landlord for refund or reimbursement; (4) bound by any termination, amendment or modification of this Lease made without Landlord's Mortgagee's consent and written approval, except for those terminations, amendments and modifications permitted to be made by Landlord without Landlord's Mortgagee's consent pursuant to the terms of the loan documents between Landlord and Landlord's Mortgagee; (5) subject to the defenses which Tenant might have against any prior lessor (including Landlord); and (6) subject to the offsets which Tenant might have against any prior lessor (including Landlord) except for those offset rights which (A) are expressly provided in this Lease, (B) relate to periods of time following the acquisition of the Premises by Landlord's Mortgagee, and (C) Tenant has provided written notice to Landlord's Mortgagee and provided Landlord's Mortgagee a reasonable opportunity to cure the event giving rise to such offset event. Landlord's Mortgagee shall have no liability or responsibility under or pursuant to the terms of this Lease or otherwise after it ceases to own an interest in the Premises. Nothing in this Lease shall be construed to require Landlord's Mortgagee to see to the application of the proceeds of any loan, and Tenant's agreements set forth herein shall not be impaired on account of any modification of the documents evidencing and securing any loan. (e)......Subordination, Non-Disturbance and Attornment Agreement. Simultaneously upon Tenant's execution of this Lease, Tenant shall execute a Subordination, Non-Disturbance and Attornment Agreement in the form attached hereto as Exhibit J. Landlord shall return a fully executed Subordination, Non-Disturbance and Attornment Agreement in the form attached hereto as Exhibit J from the Lender named therein to Tenant as soon as reasonably possible. Landlord shall use reasonable efforts to obtain a so-called "nondisturbance agreement" from any further Landlord's Mortgagee. 12. Rules and Regulations. Tenant shall comply with the rules and regulations of the Building which are attached hereto as Exhibit C. Landlord may, from time to time, change such rules and regulations for the safety, care, or cleanliness of the Building and related facilities, provided that such changes will not unreasonably interfere with Tenant's use of the Premises. Tenant shall be responsible for the compliance with such rules and regulations by each Tenant Party. 13. Condemnation. (a)......Total Taking. If the entire Building or Premises are taken by right of eminent domain or conveyed in lieu ------------ thereof (a "Taking"), this Lease shall terminate as of the date of the Taking. ------ (b)......Partial Taking - Tenant's Rights. If any part of the Building becomes subject to a Taking and such Taking will prevent Tenant from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking for a period of more than one hundred eighty (180) days, then Tenant may terminate this Lease as of the date of such Taking by giving written notice to Landlord within thirty (30) days after the Taking, and Rent shall be apportioned as of the date of such Taking. If Tenant does not terminate this Lease, then Rent shall be abated on a reasonable basis as to that portion of the Premises rendered untenantable by the Taking. (c)......Partial Taking - Landlord's Rights. If any material portion, but less than all, of the Building becomes subject to a Taking, or if Landlord is required to pay at least $50,000.00 of any of the proceeds received for a Taking to a Landlord's Mortgagee, then Landlord may terminate this Lease by delivering written notice thereof to Tenant within thirty (30) days after such Taking, and Rent shall be apportioned as of the date of such Taking. If Landlord does not so terminate this Lease, then this Lease will continue, but if any portion of the Premises has been taken, Rent shall abate as provided in the last sentence of Section 13.(b). For the purposes of this Section 13 and Section 14, the term "material portion" shall be deemed to mean at least twenty percent (20%) of the rentable square feet of the Building. (d)......Award. If any Taking occurs, then Landlord shall receive the entire award or other compensation for the land on which the Building is situated, the Building, and other improvements taken, and Tenant may separately pursue a claim (to the extent it will not reduce Landlord's award) against the condemnor for the value of Tenant's personal property which Tenant is entitled to remove under this Lease, moving costs, loss of business, and other claims it may have. 14. Fire or Other Casualty. (a)......Repair Estimate. If the Premises or the Building are damaged by fire or other casualty (a "Casualty"), Landlord shall, within 90 days after such Casualty, deliver to Tenant a good faith estimate (the "Damage Notice") of the time needed to repair the damage caused by such Casualty. (b)......Landlord's and Tenant's Rights. If a material portion of the Building is damaged by Casualty such that Tenant is prevented from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Casualty and Landlord reasonably estimates that the damage caused thereby cannot be repaired within fifteen (15) months after the Casualty (as such period may be extended by the number of days lost as a result of force majeure events up to a maximum of one hundred eighty (180) days), then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within thirty (30) days after the Damage Notice has been delivered to Tenant. If Tenant does not so timely terminate this Lease, then (subject to Section 14.(c)) Landlord shall repair the Building as provided below, and Rent for the portion of the Building rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the completion of the repair, unless a Tenant Party caused such damage, in which case, Tenant shall continue to pay Rent without abatement. (c)......Landlord's Rights. If a Casualty damages a material portion of the Building during the last three (3) years of the Term (as the Term may be extended pursuant to the provisions of Exhibit G), and Landlord makes a good faith determination that restoring the Building would be uneconomical, or if Landlord is required to pay at least $50,000.00 of any insurance proceeds arising out of the Casualty to a Landlord's Mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within thirty (30) days after the Damage Notice has been delivered to Tenant, and Basic Rent and Additional Rent shall be abated as of the date of the Casualty. (d)......Repair Obligation. If neither party elects to terminate this Lease following a Casualty, then Landlord shall, within a reasonable time after such Casualty, begin to repair the Building and shall proceed with reasonable diligence to restore the Building to substantially the same condition as it existed immediately before such Casualty; however, Landlord shall not be required to repair or replace any of the furniture, equipment, fixtures, and other improvements which may have been placed by, or at the request of, Tenant or other occupants in the Building or the Premises, and Landlord's obligation to repair or restore the Building or Premises shall be limited to the extent of the insurance proceeds actually received by Landlord for the Casualty in question. 15. Personal Property Taxes. Tenant shall be liable for all taxes levied or assessed against personal property, furniture, or fixtures placed by Tenant in the Premises. If any taxes for which Tenant is liable are levied or assessed against Landlord or Landlord's property and Landlord elects to pay the same, or if the assessed value of Landlord's property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, then Tenant shall pay to Landlord, upon demand, the part of such taxes for which Tenant is primarily liable hereunder; however, Landlord shall not pay such amount if Tenant notifies Landlord that it will contest the validity or amount of such taxes before Landlord makes such payment, and thereafter diligently proceeds with such contest in accordance with law and if the non-payment thereof does not pose a threat of loss or seizure of the Building or interest of Landlord therein or impose any fee or penalty against Landlord. 16. Events of Default. Each of the following occurrences shall be an "Event of Default": (a)......Tenant's failure to pay Rent within five (5) days after Landlord has delivered written notice to Tenant that the same is due; however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice if Landlord has given Tenant written notice under this Section 16.(a) on two (2) occasions during the twelve (12) month interval preceding such failure by Tenant; (b)......For more than thirty (30) consecutive days or more than thirty (30) days in a ninety (90) day period, Tenant (1) abandons or vacates the Building or more than twenty-five percent (25%) thereof, or (2) fails to continuously operate its business in the Building for the Permitted Use set forth herein; (c)......Tenant fails to provide any estoppel certificate within the time period required under Section 24.(e) and such failure shall continue for five (5) days after written notice thereof from Landlord to Tenant; (d)......Tenant's failure to perform, comply with, or observe any other agreement or obligation of Tenant under this Lease and the continuance of such failure for a period of more than thirty (30) days after Landlord has delivered to Tenant written notice thereof; provided that if the default is of such a nature that it may not be reasonably cured within thirty (30) days, then no Event of Default shall occur hereunder if Tenant commences curing within such thirty (30) day period and thereafter diligently and continuously pursues such cure to completion within a period of not more than forty-five (45) days after the delivery of such notice; and (e)......The filing of a petition by or against Tenant (the term "Tenant" shall include, for the purpose of this Section 16.(e), any guarantor of Tenant's obligations hereunder); (1) in any bankruptcy or other insolvency proceeding; (2) seeking any relief under any state or federal debtor relief law; (3) for the appointment of a liquidator or receiver for all or substantially all of Tenant's property or for Tenant's interest in this Lease; or (4) for the reorganization or modification of Tenant's capital structure; however, if such a petition is filed against Tenant, then such filing shall not be an Event of Default unless Tenant fails to have the proceedings initiated by such petition dismissed within sixty (60) days after the filing thereof. 17. Remedies. Upon an Event of Default, Landlord may, in addition to all other rights and remedies afforded Landlord hereunder, take any of the following actions: (a)......Terminate this Lease by giving Tenant written notice thereof, in which event Tenant shall pay to Landlord the sum of (1) all Rent accrued hereunder through the date of termination, (2) all amounts dues under Section 18.(a), and (3) an amount equal to (A) the total Rent that Tenant would have been required to pay for the remainder of the Term plus Landlord's estimate of aggregate expenses of reletting to the Premises, minus (B) the then present fair rental rate value of the Premises for such period; (b)......Terminate Tenant's right to possess the Premises without terminating this Lease by giving written notice thereof to Tenant, in which event Tenant shall pay to Landlord (1) all Rent and other amounts accrued hereunder to the date of termination of possession, (2) all amounts due from time to time under Section 18.(a), and (3) all Rent and other net sums required hereunder to be paid by Tenant during the remainder of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during such period, after deducting all costs incurred by Landlord in reletting the Premises. Landlord shall use reasonable efforts to relet the Premises on such terms as Landlord in its sole discretion may determine (including a term different from the Term, rental concessions, and alterations to, and improvement of, the Premises); however, Landlord shall not be obligated to relet the Premises before leasing space in any building owned by Landlord or any Affiliate thereof within a one (1) mile radius of the Building (the "Affiliated Buildings"). Landlord shall not be liable for, nor shall Tenant's obligations hereunder be diminished because of, Landlord's failure to relet the Premises or to collect rent due for such reletting. Tenant shall not be entitled to the excess of any consideration obtained by reletting over the Rent due hereunder. Reentry by Landlord in the Premises shall not affect Tenant's obligations hereunder for the unexpired Term; rather, Landlord may, from time to time, bring an action against Tenant to collect amounts due by Tenant, without the necessity of Landlord's waiting until the expiration of the Term. Unless Landlord delivers written notice to Tenant expressly stating that it has elected to terminate this Lease, all actions taken by Landlord to dispossess or exclude Tenant from the Premises shall be deemed to be taken under this Section 17.(b). If Landlord elects to proceed under this Section 17.(b), it may at any time elect to terminate this Lease under Section 17.(a); and (c)......Additionally, without notice and provided Landlord has exercised its rights and remedies set forth in either clause (a) or clause (b) above, Landlord may alter locks or other security devices at the Premises to deprive Tenant of access thereto, and Landlord shall not be required to provide a new key or right of access to Tenant. Any and all remedies set forth in this Lease: (i) shall be in addition to any and all other remedies Landlord may have at law or in equity; (ii) shall be cumulative; and (iii) may be pursued successively or concurrently as Landlord may elect. The exercise of any remedy by Landlord shall not be deemed an election of remedies or preclude Landlord from exercising any other remedies in the future. Notwithstanding the foregoing, Landlord shall only recover its damages allowed hereunder once. 18. Payment by Tenant; Non-Waiver. (a)......Payment by Tenant. Upon any Event of Default, Tenant shall pay to Landlord all costs incurred by Landlord (including court costs and reasonable attorneys' fees and expenses) in (1) obtaining possession of the Premises, (2) removing and storing Tenant's or any other occupant's property, (3) repairing, restoring, altering, remodeling, or otherwise putting the Premises into condition reasonably acceptable to a new tenant, (4) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part of the Premises (including brokerage commissions, cost of tenant finish work, and other costs incidental to such reletting), (5) performing Tenant's obligations which Tenant failed to perform, and (6) enforcing, or advising Landlord of, its rights, remedies, and recourses arising out of the Event of Default. To the full extent permitted by law, Landlord and Tenant agree the federal and state courts of Massachusetts shall have exclusive jurisdiction over any matter relating to or arising from this Lease and the parties' rights and obligations under this Lease. (b)......No Waiver. Landlord's acceptance of Rent following an Event of Default shall not waive Landlord's rights regarding such Event of Default. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord's rights regarding any future violation of such term. Landlord's acceptance of any partial payment of Rent shall not waive Landlord's rights with regard to the remaining portion of the Rent that is due, regardless of any endorsement or other statement on any instrument delivered in payment of Rent or any writing delivered in connection therewith; accordingly, Landlord's acceptance of a partial payment of Rent shall not constitute an accord and satisfaction of the full amount of the Rent that is due. 19. Landlord's Lien. Intentionally omitted, provided that the deletion of this Section shall not be construed to be a waiver of Landlord's lien rights provided by law. 20. Surrender of Premises. No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless it is in writing and signed by Landlord. At the expiration or termination of this Lease, Tenant shall deliver to Landlord the Premises with all improvements located therein in good repair and condition, free of Hazardous Materials placed on the Premises during the Term, broom-clean, reasonable wear and tear (and condemnation and Casualty damage not caused by Tenant, as to which Sections 13 and 14 shall control) excepted, and shall deliver to Landlord all keys to the Premises. Provided that Tenant has performed all of its obligations hereunder, Tenant may remove all unattached trade fixtures, furniture, and personal property placed in the Premises by Tenant, and shall remove such alterations, additions, improvements, trade fixtures, personal property, equipment, wiring, and furniture as Landlord may request. Tenant shall repair all damage caused by such removal. All items not so removed shall be deemed to have been abandoned by Tenant and may be appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items. The provisions of this Section 20 shall survive the end of the Term. 21. Holding Over. If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be a tenant at will and, in addition to all other damages incurred by Landlord from and after ninety (90) days after the expiration of this Lease and remedies to which Landlord may be entitled for such holding over, Tenant shall pay, in addition to the other Rent, a daily Basic Rent equal to 200% of the daily Basic Rent payable during the last month of the Term. The provisions of this Section 21 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys' fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom. 22.

J-9 EXHIBIT J SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT This AGREEMENT is made and entered into as of ___________________, 1999, by and among LaSalle National Bank, as Trustee for GS Mortgage Securities Corporation II Commercial Mortgage Pass-Through Certificates, Series 1998-GSFL1 ("Lender"), W9/TIB Real Estate Limited Partnership ("Landlord") and Kronos Incorporated ("Tenant"). 1. RECITALS. 1.1 Mortgage. Lender is the holder of a Promissory Note dated ________________, 19____, in the original principal amount of $_________________ of Landlord, which is secured, inter alia, by a Mortgage and Security Agreement (the "Mortgage") and Assignment of Lease and Rents (the "Lease Assignment") covering premises more particularly described in the Mortgage (the "Premises"). 1.2 Lease. Landlord and Tenant entered into a Lease dated January __, 1999 (the "Lease"), whereby Landlord demised to Tenant a portion of the Premises (the "Demised Premises"). 2. CONSIDERATION. The terms of the Lease constitute a material inducement to Lender's consent thereto and entering into and performing this Agreement. 3. SUBORDINATION OF THE LEASE. This Lease shall be and is hereby made subject and subordinate to the Mortgage. 4. NON-DISTURBANCE. Lender shall not, in the exercise of any right, remedy, or privilege granted by the Mortgage or the Lease Assignment, or otherwise available to Lender at law or in equity, disturb Tenant's possession under the Lease so long as: (a) Tenant is not in default under any provision of the Lease or this Agreement beyond any applicable notice and/or cure periods at the time Lender exercises any such right, remedy or privilege; and (b) The Lease at that time is in force and effect according to its original terms, or with such amendments or modifications as Lender shall have approved, if such approval is required by the terms of the Mortgage or the Lease Assignment; and (c) Tenant thereafter continues to fully and punctually perform all of its obligations under the Lease without default thereunder beyond any applicable cure period; and (d) Tenant attorns to or at the direction of Lender, as provided in Paragraph 5. Without limiting the foregoing, and so long as the foregoing conditions are met, Lender agrees that (i) Tenant will not be named as a party to any foreclosure or other proceeding instituted by Lender to enforce the terms of the Mortgage or the Lease Assignment; (ii) any sale or other transfer of the Demised Premises or of the Landlord's interest in the Lease, pursuant to foreclosure or any voluntary conveyance or other proceeding in lieu of foreclosure, will be subject and subordinate to Tenant's possession under the Lease; and (iii) the Lease will continue in force and effect according to its original terms, or with such amendments as Lender shall have approved, if such approval is required by the terms and conditions of the Mortgage or the Lease Assignment. 5. ATTORNMENT. Tenant shall attorn to Lender, to any receiver or similar official for the Demised Premises appointed at the instance and request, or with the consent, of Lender and to any person who acquires the Demised Premises, or the Landlord's interest in the Lease, or both, pursuant to Lender's exercise of any right, remedy or privilege granted by the Mortgage, or otherwise at law or in equity. Without limitation, Tenant shall attorn to any person or entity that acquired the Demised Premises pursuant to foreclosure of the Mortgage, or by any proceeding or voluntary conveyance in lieu of such foreclosure, or from Lender, whether by sale, exchange or otherwise. Any attornment to anyone other than Lender shall be conditioned upon Tenant receiving a non-disturbance from such entity. Upon any attornment under this Paragraph 5, the Lease shall continue in full force and effect as a direct lease between Tenant and the person or entity to whom Tenant attorns, except that such person or entity shall not be: (i) liable for any breach, act or omission of any prior landlord; or (ii) subject to any offsets, claims or defenses which Tenant might have against any prior landlord; or (iii)bound by any rent or additional rent or other payment in lieu of rent which Tenant might have paid to any prior landlord more than 30 days in advance of its due date under the Lease or which such person or entity has physical possession of; or (iv) bound by any amendment or modification of the Lease made without Lender's written consent, where such consent is required by the Mortgage; or (v) bound by any notice given by Tenant to Landlord, whether or not such notice is given pursuant to the terms of the Lease, unless a copy thereof was then also given to Lender; or (vi) be liable for any security deposit or other sums held by any prior landlord, unless actually received. The person or entity to whom Tenant attorns shall be liable to Tenant under the Lease only during such person or entity's period of ownership, and such liability shall not continue or survive as to the transferor after a transfer by such person or entity of its interest in the Lease and the Demised Premises. 6. REPRESENTATIONS AND WARRANTIES. 6.1 Landlord and Tenant each hereby represent and warrant to Lender as follows regarding the Lease: (a) A true and correct copy of the Lease (inclusive of all riders and exhibits thereto) is attached to the counterpart of this Agreement being delivered to Lender. There are no other oral or written agreements, understandings or the like between Landlord and Tenant relating to the Demised Premises or the Lease transaction. (b) The term of the Lease is expected to commence on or about August 1, 1999. (c) Under the Lease, Tenant shall be obligated to pay rent without present right of defense or offset, at the rate of $54,818.67 per month. Rent is paid through and including N/A , 19__. No rent has been paid more than 30 days in advance, and Tenant has no claim against the Landlord for any deposits or other sums. (d) The Lease has not been modified, altered or amended in any respect. (e) All of the improvements contemplated by the Lease have been entirely completed as required therein. (f) The addresses for notices to be sent to Tenant and Landlord are as set forth in the Lease. (g) To Tenant's knowledge, Tenant has no right of first refusal, option or other right to purchase the Premises or any part thereof, including, without limitation, the Demised Premises. 6.2 Several. Landlord and Tenant severally represent and warrant to Lender with respect to themselves, but not with respect to the other: (a) The execution of the Lease was duly authorized, the Lease was properly executed and is in full force and effect and is valid, binding and enforceable against Tenant and Landlord and there exists no monetary default or, to the best of their knowledge, no non-monetary default, nor state of facts which with notice, the passage of time, or both, could ripen into a default, on the part of either Tenant or Landlord. (b) There has not been filed by or against nor, to the best of the knowledge and belief of the representing party, is there threatened against or contemplated by, Landlord or Tenant, a petition in bankruptcy, voluntary or otherwise, any assignment for the benefit of creditors, any petition seeking reorganization or arrangement under the bankruptcy laws of the United States or of any state thereof, or any other action brought under said bankruptcy laws. (c) There has not been any assignment, hypothecation or pledge of the Lease or rents accruing under the Lease, other than pursuant to the Mortgage and the Lease Assignment. Tenant makes the representation set forth in this subparagraph only to its best knowledge and belief. 7. RENTS. Landlord and Tenant jointly and severally acknowledge that the Lease Assignment provides for the direct payment to Lender of all rents and other monies due and to become due to Landlord under the Lease upon the occurrence of certain conditions as set forth in the Lease Assignment without Lender's taking possession of the Demised Premises or otherwise assuming Landlord's position or any of Landlord's obligations under the Lease. Upon receipt from Lender of written notice to pay all such rents and other monies to or at the direction of Lender, Landlord authorizes and directs Tenant thereafter to make all such payments to or at the direction of Lender, releases Tenant of any and all liability to Landlord for any and all payment so made, and shall defend, indemnify and hold Tenant harmless from and against any and all claims, demands, losses, or liabilities asserted by, through or under Landlord (except by Lender) for any and all payments so made. Upon receipt of such notice, Tenant thereafter shall pay all monies then due and becoming due from Tenant under the Lease to or at the direction of Lender, notwithstanding any provision of the Lease to the contrary. Tenant agrees that neither Lender's demanding or receiving any such payments, nor Lender's exercising any other right, remedy, privilege, power or immunity granted by the Mortgage or the Lease Assignment, will operate to impose any liability upon Lender for performance of any obligation of Landlord under the Lease unless and until Lender elects otherwise in writing. Such payments shall continue until Lender directs Tenant otherwise in writing. Tenant agrees not to pay any rent under the Lease more than 30 days in advance without Lender's consent. The provisions of this Paragraph 7 will apply from time to time throughout the term of the Lease. 8. CURE. If Tenant becomes entitled to terminate the Lease or offset, withhold or abate rents because of any default by Landlord, then Tenant shall give Lender written notice specifying Landlord's default. Lender then shall have the right, but not the obligation, to cure the specified default within the following time periods: (a) Fifteen days after receipt of such notice with respect to defaults that can be cured by the payment of money; or (b) Thirty days after receipt of such notice with respect to any other default; unless the cure requires Lender to obtain possession of the Demised Premises, in which case such thirty day period shall not commence until Lender acquires possession, so long as Lender proceeds promptly to acquire possession of the Demised Premises with due diligence, by foreclosure of the Mortgage or otherwise. Nothing contained in this Paragraph 8 shall require Lender to commence or continue any foreclosure or other proceedings, or, if Lender acquires possession of the Demised Premises, to continue such possession, if all defaults specified by Tenant in its notice are cured. Possession by a receiver, or other similar official appointed at the instance, or with the consent, of Lender shall constitute possession by Lender for all purposes under this Paragraph 8. 9. ESTOPPEL LETTERS. Whenever reasonably requested by Lender, Landlord and Tenant from time to time shall severally execute and deliver to or at the direction of Lender, and without charge to Lender, one or more written certifications of all of the matters as set forth in Paragraph 6, whether Tenant has exercised any renewal option or options and any other information the Lender may reasonably require to confirm the current status of the Lease, including, without limitation, a confirmation that the Lease is and remains subordinated as provided in this Agreement. 10. CASUALTY AND EMINENT DOMAIN. Landlord and Tenant jointly and severally agree that the Mortgage permits Lender, at its option, to apply to the indebtedness from time to time secured by the Mortgage any and all insurance proceeds payable with respect to any casualty loss at the Demised Premises and any and all awards or other compensation that may be payable for the condemnation of all or any portion of the Demised Premises, or any interest therein, or by way of negotiated settlement or conveyance in lieu of condemnation; and Landlord and Tenant jointly and severally consent to any such application by Lender. Notwithstanding the foregoing, Landlord and Lender agree that any and all insurance or condemnation proceeds payable with respect to Tenant's property or the interruption or relocation of Tenant's business (except for rental loss insurance proceeds) will be paid to Tenant, so long as they do not reduce the proceeds otherwise payable to Lender. 11. NOTICES. All notices, demands, and other communications that must or may be given or made in connection with this Agreement must be in writing and, unless receipt is expressly required, will be deemed delivered or made 5 days after having been mailed by registered or certified mail, return receipt requested, or by express mail, in any event with sufficient postage affixed, and addressed to the parties as follows: TO LENDER: c/o AMRESCO Services, L.P. 235 Peachtree Street, N.E., Suite 900 Atlanta, Georgia 30303 Attn.: Private Sector Servicing TO LANDLORD:W9/TIB Real Estate Limited Partnership c/o Archon Group, L.P. 1275 K Street NW, Suite 900 Washington, DC 20005 TO TENANT: Kronos Incorporated 400 Fifth Avenue Waltham, MA 02151 Such addresses may be changed by notice pursuant to this Paragraph 11; but notice of change of address is effective only upon receipt.

Subject to the foregoing, this Agreement shall bind and inure to the benefit of Landlord, Tenant and Lender, their legal representatives, successors and assigns. The terms Lease, Mortgage and Lease Assignment shall include any and all amendments, modifications, replacements, substitutions, extensions, renewals and supplements thereto. 13. FURTHER ASSURANCES. Landlord and Tenant from time to time shall execute and deliver at Lender's request all instruments that may be necessary or appropriate to evidence their agreement hereunder provided such instrument neither increases Tenant's obligations or decreases its rights under the Lease. 14. COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and all such counterparts shall constitute one and the same instrument. 15. SEVERABILITY. A determination that any provision of this Agreement is unenforceable or invalid shall not affect the enforceability or validity of any other provision, and any determination that the application of any provision of this Agreement to any person or to any person or to particular circumstances is illegal or unenforceable shall not affect the enforceability or validity of such provision as it may apply to other persons or circumstances. IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first above written.

Tenant shall notify Landlord in writing whether Tenant elects to lease the entire 4 Omni Way Offer Space on the terms set forth in the 4 Omni Way Offer Notice, within seven (7) business days after Landlord delivers to Tenant the 4 Omni Way Offer Notice. If Tenant timely elects to lease the 4 Omni Way Offer Space, then Landlord and Tenant shall, at Landlord's sole discretion, execute a new lease agreement for the 4 Omni Way Offer Space or an amendment to this Lease within thirty (30) days after Tenant's election, effective as of the date the 4 Omni Way Offer Space is available for lease, on the terms set forth in the 4 Omni Way Offer Notice and, to the extent not inconsistent with the 4 Omni Way Offer Notice terms, the terms of this Lease. If Tenant fails or is unable to timely exercise its right hereunder, then such right shall lapse, time being of the essence with respect to the exercise thereof, and Landlord may lease all or a portion of the 4 Omni Way Offer Space to third parties on such terms as Landlord may elect. Notwithstanding the foregoing, if Landlord leases less than one-half of the 4 Omni Way Offer Space to a third party, Tenant's right of first offer granted under this Exhibit shall continue with respect to the remainder of the 4 Omni Way Offer Space not leased to such third party; provided, however, if Tenant fails or is unable to timely exercise its rights hereunder with respect to the remainder of the 4 Omni Way Offer Space, then such right to lease the remainder of the 4 Omni Way Offer Space shall lapse, time being of the essence with respect to the exercise thereof, and Landlord may lease all or a portion of the remainder of the 4 Omni Way Offer Space to third parties on such terms as Landlord may elect. Further, but subject to the provisions of the preceding sentence, Tenant's right of first offer granted under this Exhibit with respect to the 4 Omni Way Offer Space shall continue during the initial Term on the same terms and conditions set forth herein to the extent the 4 Omni Way Offer Space again becomes available during the initial Term. Tenant may not exercise its rights under this Exhibit if an Event of Default exists, if Tenant is not then occupying at least seventy-five percent (75%) of the Premises, or if Tenant has a net worth that is less than ninety-five percent (95%) of Tenant's net worth as of the date hereof. For purposes hereof, if a 4 Omni Way Offer Notice is delivered for less than all of the 4 Omni Way Offer Space but such notice provides for an expansion, right of first refusal, or other preferential right to lease some of the remaining portion of the 4 Omni Way Offer Space, then such remaining portion of the 4 Omni Way Offer Space shall thereafter be excluded from the provisions of this Exhibit. Tenant's rights under this Exhibit shall terminate if (a) this Lease or Tenant's right to possession of the Premises is terminated, (b) Tenant assigns any of its interest in this Lease or sublets more than twenty-five percent (25%) of the Premises, or (c) the initial Term expires. Notwithstanding any provisions of this Lease to the contrary, if the fee title to the 4 Omni Way Offer Space is held by an entity other than Landlord or any Affiliate of Landlord and such entity fails to comply with the provisions of this Exhibit K, Tenant shall have no recourse, rights or remedies against Landlord if such entity fails to comply with the provisions of this Exhibit K and Tenant shall continue to comply with the provisions of this Lease.
