Landlord represents that it holds title to the FFE and, in consideration for the terms set forth in this Lease, Landlord agrees to allow Tenant to utilize the FEE during the Lease Term. Tenant may, as it deems appropriate or necessary, reconfigure the furniture and petitions included in the FFE to combine with any of Tenant’s furniture, fixtures and equipment, however, Tenant may not remove any FFE from the Premises without Landlord’s prior consent. With respect to the HVAC and back-up generator systems and accompanying equipment, Tenant agrees to maintain at all times a service contract satisfactory to Landlord with respect thereto, furnishing evidence thereof (including renewals) to Landlord. Such contracts shall provide, at a minimum, for at least quarterly servicing. Landlord makes no representation as to the fitness or suitability of the FFE for Tenant’s purposes.

Further, Landlord assumes no responsibility whatsoever for loss or damage due to fire, theft or otherwise to any automobile(s) parked on the Site or to any personal property therein, however caused, except to the extent of any such loss caused by the gross negligence or willful misconduct of Landlord or Landlord’s agents, contractors, or employees. Tenant covenants and agrees, upon request from Landlord from time to time, to notify its officers, employees, agents and invitees of such limitation of liability.

Annual Fixed Rent for any partial month shall be paid by Tenant to Landlord at such rate on a pro rata basis, and, if the Commencement Date is a day other than the first day of a calendar month, the first payment of Annual Fixed Rent which Tenant shall make to Landlord shall be a payment equal to a proportionate part of such monthly Annual Fixed Rent for the partial month from the Commencement Date to the first day of the succeeding calendar month.

Additional Rent payable by Tenant on a monthly basis, as hereinafter provided, likewise shall be prorated, and the first payment on account thereof shall be determined in similar fashion but shall commence on the Commencement Date; and other provisions of this Lease calling for monthly payments shall be read as incorporating this undertaking by Tenant.

“Operating Expenses Allocable to the Premises” shall mean (a) the same proportion of Landlord’s Operating Expenses for and pertaining to the Building as the Rentable Floor Area of Tenant’s Space bears to the Total Rentable Floor Area of the Building (which proportion as of the Commencement Date is 100%) plus (b) the same proportion of Landlord’s Operating Expenses for and pertaining to the Site as the Rentable Floor Area of Tenant’s Space bears to the Total Rentable Floor Area of the Buildings (which proportion as of the Commencement Date is 64.24%).

If with respect to any calendar year falling within the Term, or fraction of a calendar year falling within the Term at the beginning or end thereof, the Operating Expenses Allocable to the Premises for a full calendar year exceed Base Operating Expenses Allocable to the Premises, or for any such fraction of a calendar year exceed the corresponding fraction of Base Operating Expenses Allocable to the Premises then, Tenant shall pay to Landlord, as Additional Rent, the amount of such excess. Such payments shall be made at the times and in the manner hereinafter provided in this Section 2.6.

Not later than one hundred and twenty (120) days after the end of the first calendar year or fraction thereof ending December 31 and of each succeeding calendar year during the Term or fraction thereof at the end of the Term, Landlord shall render Tenant a statement in reasonable detail and according to usual accounting practices certified by a representative of Landlord, showing for the preceding calendar year or fraction thereof, as the case may be, Landlord’s Operating Expenses and Operating Expenses Allocable to the Premises (identifying in detail those expenses solely attributable to the Building and those attributable to the Complex). Said statement to be rendered to Tenant shall also show for the preceding year or fraction thereof as the case may be the amounts of operating expenses already paid by Tenant as Additional Rent, and the amount of operating expenses remaining due from, or overpaid by, Tenant for the year or other period covered by the statement. Within thirty (30) days after the date of delivery of such statement, Tenant shall pay to Landlord the balance of the amounts, if any, required to be paid pursuant to the above provisions of this Section 2.6 with respect to the preceding year or fraction thereof, or Landlord shall credit any amounts due from it to Tenant pursuant to the above provisions of this Section 2.6 against (i) monthly installments of fixed rent next thereafter coming due or (ii) any sums then due from Tenant to Landlord under this Lease (or refund such portion of the overpayment as aforesaid if the Term has ended and Tenant has no further obligation to Landlord). Upon no less than three (3) business days prior notice to Landlord (given within thirty (30) days after Tenant’s receipt of such annual statement) (“Tenant’s Audit Notice”), Tenant, at Tenant’s expense, may examine Landlord’s books and records regarding such statement at any reasonable time specified by Landlord during Landlord’s business hours at a place designated by Landlord. Such audit must be completed within sixty (60) days of the effective date of Tenant’s Audit Notice. Tenant shall hold such books and records in confidence and not disclose the same to any other party, including, without limitation, any other tenant in the Complex. If such examination reveals that Landlord’s Operating Expenses for such calendar year have been (a) overstated by Landlord, then an equitable adjustment shall be made in the amount paid or payable pursuant to this Section 2.6 for such calendar year, and appropriate credit shall be made against (i) monthly installments of Annual Fixed Rent or Additional Rent next thereafter coming due or (ii) any other sums due from Tenant to Landlord under this Lease (or refund such amount if the Term has ended and Tenant has no further obligation to Landlord other than an indemnification obligation for which no claim has been made) or (b) understated by Landlord, then an equitable adjustment shall be made in the amount paid or payable pursuant to this Section 2.6 for such calendar year and an appropriate payment shall be made by Tenant to Landlord within thirty (30) days after Landlord bills Tenant therefor. In addition, if Tenant’s examination determines that Landlord has overcharged Tenant on account of the Landlord’s Operating Expenses by more than five percent (5%), Landlord shall reimburse Tenant for the reasonable, out-of-pocket expenses incurred by Tenant in performing such examination.

In addition, Tenant shall make payments monthly on account of Tenant’s share of increases in Landlord’s Operating Expenses anticipated for the then current year at the time and in the fashion herein provided for the payment of fixed rent. The amount to be paid to Landlord shall be an amount reasonably estimated annually by Landlord to be sufficient to cover, in the aggregate, a sum equal to Tenant’s share of such increases in operating expenses for each calendar year during the Term.

Notwithstanding the foregoing provisions, no decrease in Landlord’s Operating Expenses shall result in a reduction of the amount otherwise payable by Tenant if and to the extent said decrease is attributable to vacancies in the Buildings rather than to any other causes.

2.7 REAL ESTATE TAXES. If with respect to any full Tax Year or fraction of a Tax Year falling within the Term, Landlord’s Tax Expenses Allocable to the Premises as hereinafter defined for a full Tax Year exceed Base Taxes Allocable to the Premises, or for any such fraction of a Tax Year exceed the corresponding fraction of Base Taxes Allocable to the Premises then, on or before the thirtieth (30th) day following receipt by Tenant of the certified statement referred to below in this Section 2.7, Tenant shall pay to Landlord, as Additional Rent, the amount of such excess. Not later than ninety (90) days after Landlord’s Tax Expenses Allocable to the Premises are determined for the first such Tax Year or fraction thereof and for each succeeding Tax Year or fraction thereof during the Term, Landlord shall render Tenant a statement in reasonable detail certified by a representative of Landlord showing for the preceding year or fraction thereof, as the case may be, real estate taxes on the Building and the Site and abatements and refunds of any taxes and assessments. Expenditures for legal fees and for other expenses incurred in obtaining the tax refund or abatement may be charged against the tax refund or abatement before the adjustments are made for the Tax Year. Said statement to be rendered to Tenant shall also show for the

preceding year or fraction thereof as the case may be the amounts of real estate taxes already paid by Tenant as Additional Rent, and the amount of real estate taxes remaining due from, or overpaid by, Tenant for the year or other period covered by the statement. Within thirty (30) days after the date of delivery of the foregoing statement, Tenant shall pay to Landlord the balance of the amounts, if any, required to be paid pursuant to the above provisions of this Section 2.7 with respect to the preceding year or fraction thereof, or Landlord shall credit any amounts due from it to Tenant pursuant to the provisions of this Section 2.7 against (i) monthly installments of fixed rent next thereafter coming due or (ii) any sums then due from Tenant to Landlord under this Lease (or refund such portion of the over-payment as aforesaid if the Term has ended and Tenant has no further obligation to Landlord).

To the extent permitted by applicable law and provided there shall not then be existing an Event of Default, there is a minimum of twelve (12) full calendar months remaining in the Term (as it may have been extended) and Tenant has given prior written notice to Landlord, Tenant shall have the right to contest the amount or validity, in whole or in part, of any of the real estate taxes by appropriate proceedings diligently conducted in good faith; provided, however, that as a continuing condition to such right, Tenant shall be required to make those payments respecting real state taxes as and at the times required by law notwithstanding any such contest. Tenant further agrees that each such contest shall be promptly and diligently prosecuted in good faith to a final conclusion except only as provided herein. Landlord agrees to cooperate with Tenant in any such proceeding provided that the same shall be at the sole cost and expense of Tenant. Tenant will pay and save Landlord harmless against any and all losses, judgments, decrees and costs incurred by Landlord (including reasonable attorneys’ fees) relating to the Premises and the Term hereof and being the direct or proximate result of Tenant’s initiation of such contest and will, promptly after the final settlement, compromise or determination of such contest, fully pay and discharge Tenant’s obligations under this Section 2.7, together with all penalties, fines, interests, costs and expenses. Further, any such contest by Tenant shall not be discontinued unless and until Tenant has given to Landlord written notice of Tenant’s intent to so discontinue and if Landlord shall not by notice to Tenant (the “Assumption Notice”) within thirty (30) days after receipt of Tenant’s notice elect to assume, at Landlord’s sole cost and expense, the continued prosecution and conduct of such contest. In the event Landlord shall give such Assumption Notice, Tenant shall cooperate with Landlord in all respects as may be necessary for Landlord’s continuation of such contest, but Tenant shall have no other obligation for the prosecution and conduct of such contest.

In addition, payments by Tenant on account of increases in real estate taxes anticipated for the then current year shall be made monthly at the time and in the fashion herein provided for the payment of fixed rent. The amount so to be paid to Landlord shall be an amount reasonably estimated by Landlord to be sufficient to provide Landlord, in the aggregate, a sum equal to Tenant’s share of such increases, at least ten (10) days before the day on which such payments by Landlord would become delinquent.

To the extent that real estate taxes shall be payable to the taxing authority in installments with respect to periods less than a Tax Year, the foregoing statement shall be rendered and payments made on account of such installments. Notwithstanding the foregoing provisions, no decrease in Landlord’s Tax Expenses with respect to any Tax Year shall result in a reduction of the amount otherwise payable by Tenant if and to the extent said decrease is attributable to vacancies in the Building or partial completion of the Building rather than to any other causes.

Terms used herein are defined as follows:

(i) “Tax Year” means the twelve-month period beginning July 1 each year during the Term or if the appropriate governmental tax fiscal period shall begin on any date other than July 1, such other date.

(ii) “Landlord’s Tax Expenses Allocable to the Premises” shall mean (a) the same proportion of Landlord’s Tax Expenses for and pertaining to the Building as the Rentable Floor Area of Tenant’s Space bears to the Total Rentable Floor Area of the Building plus (b) the same proportion of Landlord’s Tax Expenses for and pertaining to the Site as the Rentable Floor Area of Tenant’s Space bears to the Total Rentable Floor Area of the Buildings.

Such assignment or subletting shall not relieve the Tenant named herein of any of the obligations of the Tenant hereunder and Tenant shall remain fully and primarily liable therefor and the liability of Tenant and such assignee (or subtenant, as the case may be) shall be joint and several. Further, and notwithstanding the foregoing, the provisions hereof shall not constitute a recognition of the assignment or the assignee thereunder or the sublease or the subtenant thereunder, as the case may be, and at Landlord’s option, upon the termination or expiration of the Lease (whether such termination is based upon a cause beyond Tenant’s control, a default of Tenant, the agreement of Tenant and Landlord or any other reason), the assignment or sublease shall be terminated.

(B) As Additional Rent, Tenant shall reimburse Landlord promptly for reasonable out of pocket legal and other expenses incurred by Landlord in connection with any request by Tenant for consent to assignment or subletting which shall not exceed $1,500 for each request.

(D) The consent by Landlord to an assignment or subletting under any of the provisions of Sections 5.6.1 or 5.6.2 shall in no way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting.

(E) On or after the occurrence of an “Event of Default” (defined in Section 7.1), Landlord shall be entitled to one hundred percent (100%) of any Assignment/Sublease Profits.

That all of 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 elsewhere in the Building or on the Site, shall be at the sole risk and hazard of Tenant, 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 be borne by Landlord, except that Landlord shall in no event be indemnified or held harmless or exonerated from any liability to Tenant or to any other person, for any injury, loss, damage or liability to the extent such indemnity, hold harmless or exoneration is prohibited by law. Further, Tenant, at Tenant’s expense, shall maintain at all times during the Term of this Lease business interruption insurance and insurance against loss or damage covered by so-called “all risk” type insurance coverage with respect to Tenant’s fixtures, equipment, goods, wares and merchandise, tenant improvements made by or paid for by Tenant, and other property of Tenant

In addition, during such time as Tenant is performing work in or to the Premises, Tenant, at Tenant’s expense, shall also maintain builder’s risk insurance (or equivalent insurance) for the full insurable value of such work.

Notwithstanding the foregoing, the building superintendent and those individuals involved in the cleaning and regular daily maintenance of the Building shall not be subject to the Entry Requirements (except when entering the “Engineering Area” as shown on Exhibit D attached hereto when such Entry Requirements shall apply). Further notwithstanding anything in the foregoing to the contrary, in the event of an emergency that could cause damage to health, safety or property, Landlord shall use good faith efforts to follow Tenant’s security requirements and in such event Landlord will be required to give only such notice that it in good faith believes is feasible under the circumstances and need not wait to be accompanied by Tenant or its employees or representatives (although these parties may still accompany Landlord if they are available and wish to do so).

5.10 FLOOR LOAD; PREVENTION OF VIBRATION AND NOISE. Not to place a load upon the Premises exceeding an average rate of 70 pounds of live load per square foot of floor area (partitions shall be considered as part of the live load); and not to move any safe, vault or other heavy equipment in, about or out of the Premises except in such manner and at such time as Landlord shall in each instance authorize; Tenant’s business machines and mechanical equipment which cause vibration or noise that may be transmitted to the Building structure or to any other space in the Building shall be so installed, maintained and used by Tenant so as to eliminate such vibration or noise.

Tenant shall promptly pay all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Section 5.12.

5.13 Intentionally Omitted.

5.14 ALTERATIONS. (A) Tenant shall not make alterations and additions to Tenant’s space except in accordance with plans and specifications therefor first approved by Landlord, which approval shall not be unreasonably withheld. However, Landlord’s determination of matters relating to aesthetic issues relating to alterations, additions or improvements which are visible outside the Premises shall be in Landlord’s sole discretion. Without limiting such standard Landlord shall not be deemed unreasonable for withholding approval of any alterations or additions which (a) in Landlord’s opinion might adversely affect any structural or exterior element of the Building, any area or element outside of the Premises, or any facility or base building mechanical system serving any area of the Building outside of the Premises, or (b) involve or affect the exterior design, size, height, or other

exterior dimensions of the Building or (c) will require unusual expense to readapt the Premises to normal office use on Lease termination or expiration or increase the cost of insurance or taxes on the Building unless Tenant first gives assurance acceptable to Landlord for payment of such increased cost and that such readaptation will be made prior to such termination or expiration without expense to Landlord, or (d) enlarge the Rentable Floor Area of the Premises. Landlord’s review and approval of any such plans and specifications and consent to perform work described therein shall not be deemed an agreement by Landlord that such plans, specifications and work conform with applicable Legal Requirements and requirements of insurers of the Building and the other requirements of this Lease with respect to Tenant’s insurance obligations (herein called “Insurance Requirements”) nor deemed a waiver of Tenant’s obligations under this Lease with respect to applicable Legal Requirements and Insurance Requirements nor impose any liability or obligation upon Landlord with respect to the completeness, design sufficiency or compliance of such plans, specifications and work with applicable Legal Requirements and Insurance Requirements. Within thirty (30) days after receipt of an invoice from Landlord, Tenant shall pay to Landlord as a fee for Landlord’s review of any work or plans (excluding any review respecting additions, alterations or improvements which do not require Landlord’s consent), as Additional Rent, an amount equal to the sum of: (i) $150.00 per hour for senior staff and $100.00 per hour for junior staff (not to exceed $2,000 in any instance), plus (ii) reasonable, actual third party expenses incurred by Landlord to review Tenant’s plans and Tenant’s work. All alterations and additions shall be part of the Building unless and until Landlord shall specify the same for removal pursuant to Section 5.2. Except for any additions or alterations which Tenant requests to remain in the Premises in Tenant’s notice seeking Landlord’s consent for the installation thereof (which notice shall specifically refer to this Section 5.14) and for which Landlord specifically agrees in writing may remain, all of Tenant’s alterations and additions and installation of furnishings shall be coordinated with any work being performed by Landlord and in such manner as to maintain harmonious labor relations and not to damage the Buildings or Site or interfere with construction or operation of the Additional Building and other improvements to the Site and, except for installation of furnishings, shall be performed by contractors or workers first approved by Landlord, such approval not to be unreasonably withheld or delayed. Except for work by Landlord’s general contractor, Tenant, before its work is started, shall secure all licenses and permits necessary therefor; deliver to Landlord a statement of the names of all its contractors and subcontractors and the estimated cost of all labor and material to be furnished by them and security satisfactory to Landlord protecting Landlord against liens arising out of the furnishing of such labor and material; and cause each contractor to carry worker’s compensation insurance in statutory amounts covering all the contractor’s and subcontractor’s employees and commercial general liability insurance or comprehensive general liability insurance with a broad form comprehensive liability endorsement with such limits as Landlord may reasonably require, but in no event less than $2,000,000.00 combined single limit per occurrence on a per location basis (all such insurance to be written in companies approved by Landlord and naming and insuring Landlord and Landlord’s managing agent as additional insureds and insuring Tenant as well as the contractors), and to deliver to Landlord certificates of all such insurance. Tenant shall also prepare and submit to Landlord a set of as-built plans, in both print and electronic forms, showing such work performed by Tenant to the Premises promptly after any such alterations, improvements or installations are substantially complete and promptly after any wiring or cabling for Tenant’s computer, telephone and other communications systems is installed by Tenant or Tenant’s contractor. Without limiting any of Tenant’s obligations hereunder, Tenant shall be responsible, as Additional Rent, for the costs of any alterations, additions or improvements in or to the Building that are required in order to comply with Legal Requirements as a result of any work performed by Tenant. Landlord shall have the right to provide such rules and regulations relative to the performance of any alterations, additions, improvements and installations by Tenant hereunder and Tenant shall abide by all such reasonable rules and regulations and shall cause all of its contractors to so abide including, without limitation, payment for the costs of using Building services. Tenant agrees to pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees, or independent contractors, and not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the Premises or the Buildings or the Site and immediately to discharge any such liens which may so attach by payment, bond or otherwise. Notwithstanding the foregoing to the contrary, Tenant may contest, and need not discharge or bond any such lien while so doing, provided that: (i) no action to foreclose any such lien has been brought in any judicial or quasi-judicial action, (ii) such contest shall be at Tenant’s sole cost and expense, (iii) such contest shall be by appropriate legal proceedings conducted in good faith and with due diligence, (iv) such contest will not materially and adversely interfere with the possession, use or occupancy or sale or financing of the Building or Complex, (v) such contest will not subject Landlord to any civil or criminal liability (other than for the amounts being contested), (vi) no Event of Default is then continuing and (vii) such contest will not cause Landlord or any affiliate of Landlord to be in violation of any agreement to which it is bound, including, without limitation, any loan document.

(B) Notwithstanding the terms of Section 5.14(A), Tenant shall have the right, without obtaining the prior consent of Landlord, to make alterations, additions or improvements to the Premises where:

(i) the same are within the interior of the Premises within the Building, and do not affect the exterior of the Premises and the Building (including no signs on windows);

(ii) the same do not affect the roof, any structural element of the Building, the mechanical, electrical, plumbing, heating, ventilating, air-conditioning and fire protection systems of the Building;

(iii) the cost of any individual alteration, addition or improvement shall not exceed $15,000.00 and the aggregate cost of said alterations, additions or improvements made by Tenant during the Lease Term shall not exceed $70,000.00 in cost; and

(iv) Tenant shall comply with the provisions of this Lease and if such work increases the cost of insurance or taxes or of services, Tenant shall pay for any such increase in cost;

provided, however, that Tenant shall, within fifteen (15) days prior to the making of such changes, send to Landlord plans and specifications describing the same in reasonable detail and provided further that Landlord, by notice to Tenant given at least thirty (30) days prior to the expiration or earlier termination of the Lease Term, may require Tenant to restore the Premises to its condition prior to such alteration, addition or improvement at the expiration or earlier termination of the Lease Term. Landlord and Tenant acknowledge and agree that carpeting and painting of the interior of the Premises are not alterations or additions, and do not require Landlord’s consent.

5.15 VENDORS. Any vendors engaged by Tenant to perform services in or to the Premises including, without limitation, janitorial contractors and moving contractors shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations and not to damage the Building or the Property (unless such damage is promptly repaired by Tenant) or unreasonably interfere with Building construction or operation and shall be performed by vendors first approved by Landlord.

5.16 ROOF INSTALLATIONS. Notwithstanding anything contained in this Lease to the contrary, Tenant shall be permitted to install antennas and other telecommunications equipment (“Telecom Equipment”) on the rooftop of the Building only: (i) with Landlord’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), (ii) if Tenant has obtained all necessary permits and approvals required therefor, (iii) for the purpose of Tenant’s conduct of the Permitted Uses within the Premises, (iv) such installation and the operation thereof shall not interfere with any existing communication equipment on the Building or any neighboring property and (v) such installation does not adversely affect the structural element of the Building or the visual aesthetic of the Building in Landlord’s sole discretion. Upon the earlier of (x) the date upon which Tenant discontinues all use of such Telecom Equipment or (y) the expiration or earlier termination of the Lease Term, Tenant shall remove the Telecom Equipment and repair any damage to the roof caused by any such installation or removal. The indemnification provisions of Section 5.7 of this Lease shall be deemed to include any claims, liabilities, damages and expenses, including reasonable attorneys fees, relating to, or claimed to relate to, the installation, maintenance, operation or use of the Telecom Equipment installed by Tenant. Tenant shall have no right to license, sublease, assign or otherwise transfer its rights to install and use Telecom Equipment on the Site (other than to an assignee or subtenant permitted under Section 5.6.1 above). Landlord hereby reserves the right (at its sole discretion) to install and to permit others to install, use and maintain telecommunications equipment, antennas and similar installations on the rooftop of the Building and elsewhere on the Site provided that any agreement with a third party granting the right to install telecommunication equipment subsequent to the Commencement Date hereof shall contain language prohibiting interference with Tenant’s Telecom Equipment then existing and shall provide Landlord with a termination right if such interference is not remedied after a reasonable period of time. If measurable interference shall occur, Tenant shall provide notice thereof to Landlord and Landlord shall use reasonable efforts to cause the same to be remedied, however, if despite such efforts the same are not remedied within a period reasonably necessary to cure such interference), Landlord shall exercise the termination right set forth in its agreement with such interfering party. Further, Landlord shall at all times during the Term reserve a minimum of 20 square feet of cumulative and not necessarily contiguous space on the roof for Tenant’s Telecom Equipment.

ARTICLE VI

CASUALTY AND TAKING

6.1 DAMAGE RESULTING FROM CASUALTY. In case during the Lease Term the Building or the Site are damaged by fire or casualty and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within one hundred twenty (120) days from the time that repair work would commence, Landlord may, at its election, terminate this Lease by notice given to Tenant within forty-five (45) days after the date of such fire or other casualty, specifying the effective date of termination. The effective date of termination specified by Landlord shall not be less than thirty (30) days nor more than forty-five (45) days after the date of notice of such termination.

In case during the last year of the Lease Term, the Premises are damaged by fire or casualty and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within one hundred eighty (180) days from the date of such fire, casualty or damage, Tenant may, at its election, terminate this Lease by notice given to Landlord within thirty (30) days after the date of such fire or other casualty, specifying the effective date of termination. The effective date of termination specified by Tenant shall be not less than thirty (30) days nor more than forty-five (45) days after the date of notice of such termination.

Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such damage subject, however, to the following provisions.

If the Building or the Site or any part thereof are damaged by fire or other casualty and this Lease is not so terminated, or Landlord or Tenant have no right to terminate this Lease, and in any such case the holder of any mortgage which includes the Building as a part of the mortgaged premises or any ground lessor of any ground lease which includes the Site as part of the demised premises allows the net insurance proceeds to be applied to the restoration of the Building (and/or the Site), Landlord promptly after such damage and the determination of the net amount of insurance proceeds available shall use due diligence to restore the Premises and the Building in the event of damage thereto (excluding Tenant’s Property) into proper condition for use and occupation and a just proportion of the Annual Fixed Rent, Tenant’s share of Operating Expenses and Tenant’s share of real estate taxes according to the nature and extent of the injury to the Premises shall be abated until the Premises shall have been put by Landlord substantially into such condition except for punch list items and long lead items. Notwithstanding anything herein contained to the contrary, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net insurance proceeds.

Unless such restoration is completed within nine (9) months from the date of the casualty (whether or not the casualty is the result of a risk covered by the forms of insurance at the time maintained by Landlord) or taking, such period to be subject, however, to extension where the delay in completion of such work is due to Force Majeure, as defined hereinbelow, (but in no event beyond fifteen (15) months from the date of the casualty or taking), Tenant, as its sole and exclusive remedy, shall have the right to terminate this Lease at any time after the expiration of such nine-month (as extended) period until the restoration is substantially completed, such termination to take effect as of the thirtieth (30th) day after the date of receipt by Landlord of Tenant’s notice, with the same force and effect as if such date were the date originally established as the expiration date hereof unless, within thirty (30) days after Landlord’s receipt of Tenant’s notice, such restoration is substantially completed, in which case Tenant’s notice of termination shall be of no force and effect and this Lease and the Lease Term shall continue in full force and effect. When used herein, “Force Majeure” shall mean any prevention, delay or stoppage due to governmental regulation, strikes, lockouts, acts of God, acts of war, terrorists acts, civil commotions, unusual scarcity of or inability to obtain labor or materials, labor difficulties, casualty or other causes reasonably beyond Landlord’s control or attributable to Tenant’s action or inaction.

6.2 UNINSURED CASUALTY. Notwithstanding anything to the contrary contained in this Lease, if the Building or the Premises shall be substantially damaged by fire or casualty as the result of a risk not covered by the forms of casualty insurance at the time maintained by Landlord and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within ninety (90) days from the time that repair work would commence, Landlord may, at its election, terminate the Term of this Lease by notice to the Tenant given within sixty

(60) days after such loss. If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof.

6.3 RIGHTS OF TERMINATION FOR TAKING. If the entire Building, or such portion of the Premises as to render the balance (if reconstructed to the maximum extent practicable in the circumstances) unsuitable for Tenant’s purposes, shall be taken by condemnation or right of eminent domain, Landlord or Tenant shall have the right to terminate this Lease by notice to the other of its desire to do so, provided that such notice is given not later than thirty (30) days after Tenant has been deprived of possession. If either party shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof.

Further, if so much of the Building shall be so taken that continued operation of the Building would be uneconomic as a result of the taking, Landlord shall have the right to terminate this Lease by giving notice to Tenant of Landlord’s desire to do so not later than thirty (30) days after Tenant has been deprived of possession of the Premises (or such portion thereof as may be taken). If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof.

Should any part of the Premises be so taken or condemned during the Lease Term hereof, and should this Lease not be terminated in accordance with the foregoing provisions, and the holder of any mortgage which includes the Premises as part of the mortgaged premises or any ground lessor of any ground lease which includes the Site as part of the demised premises allows the net condemnation proceeds to be applied to the restoration of the Building, Landlord agrees that after the determination of the net amount of condemnation proceeds available to Landlord, Landlord shall use due diligence to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior to such taking as shall be practicable (excluding Tenant’s Property). Notwithstanding the foregoing, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net condemnation proceeds made available to it.

If the Premises shall be affected by any exercise of the power of eminent domain, then the Annual Fixed Rent, Tenant’s share of operating costs and Tenant’s share of real estate taxes shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant; and in case of a taking which permanently reduces the Rentable Floor Area of the Premises, a just proportion of the Annual Fixed Rent, Tenant’s share of operating costs and Tenant’s share of real estate taxes shall be abated for the remainder of the Lease Term.

6.4 AWARD. Landlord shall have and hereby reserves to itself any and all rights to receive awards made for damages to the Premises, the Buildings, the Complex and the Site 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 grants, releases and assigns to Landlord all Tenant’s rights to such awards, and covenants to execute and deliver such further assignments and assurances thereof as Landlord may from time to time request, and if Tenant shall fail to execute and deliver the same within fifteen (15) days after notice from Landlord, Tenant hereby covenants and agrees that Landlord shall be irrevocably designated and appointed as its attorney-in-fact to execute and deliver in Tenant’s name and behalf all such further assignments thereof which conform with the provisions hereof.

Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceeding a claim for the value of any of Tenant’s trade fixtures installed in the Premises by Tenant at Tenant’s expense and for relocation and moving expenses, provided that such action and any resulting award shall not affect or diminish the amount of compensation otherwise recoverable by Landlord from the taking authority.

ARTICLE VII

7.1 TENANT’S DEFAULT. (a) If at any time subsequent to the date of this Lease any one or more of the following events (herein sometimes called an “Event of Default”) shall occur:

(i) Tenant shall fail to pay the fixed rent and regularly scheduled payments of Additional Rent on or before the date on which the same become due and payable, and the same continues for five (5) days after notice from Landlord thereof; or

(v) Tenant shall neglect or fail to perform or observe any other covenant herein contained on Tenant’s part to be performed or observed and Tenant shall fail to remedy the same within thirty (30) days after notice to Tenant specifying such neglect or failure, or if such failure is of such a nature that Tenant cannot reasonably remedy the same within such thirty (30) day period, Tenant shall fail to commence promptly to remedy the same and to prosecute such remedy to completion with diligence and continuity; or

(vi) Tenant’s leasehold interest in the Premises shall be taken on execution or by other process of law directed against Tenant; or

(vii) Tenant shall make an assignment for the benefit of creditors or shall file a voluntary petition in bankruptcy or shall be adjudicated bankrupt or insolvent, or shall file any petition or answer seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief for itself under any present or future Federal, State or other statute, law or regulation for the relief of debtors, or shall seek or consent to or acquiesce in the appointment of any trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties, or shall admit in writing its inability to pay its debts generally as they become due; or

(viii) A petition shall be filed against Tenant in bankruptcy or under any other law seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution, or similar relief under any present or future Federal, State or other statute, law or regulation and shall remain undismissed or unstayed for an aggregate of sixty (60) days, or if any debtor in possession (whether or not Tenant) trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties or of the Premises shall be appointed without the consent or acquiescence of Tenant and such appointment shall remain unvacated or unstayed for an aggregate of sixty (60) days then, and in any of said cases (notwithstanding any license of a former breach of covenant or waiver of the benefit hereof or consent in a former instance), Landlord lawfully may, immediately or at any time thereafter, and without demand or further notice terminate this Lease by notice to Tenant, specifying a date not less than ten (10) days after the giving of such notice on which this Lease shall terminate, and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Lease Term (Tenant hereby waiving any rights of redemption), and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided.

(b) If this Lease shall have been terminated as provided in this Article, then Landlord may, without notice, re- enter the Premises, either by force, summary proceedings, ejectment or otherwise, and remove and dispossess Tenant and all other persons and any and all property from the same, as if this Lease had not been made, and Tenant hereby waives the service of notice of intention to re-enter or to institute legal proceedings to that end.

(c) In the event that this Lease is terminated under any of the provisions contained in Section 7.1 (a) or shall be otherwise terminated by breach of any obligation of Tenant, Tenant covenants and agrees forthwith to pay and be liable for, on the days originally fixed herein for the payment thereof, amounts equal to the several installments of

rent and other charges reserved as they would, under the terms of this Lease, become due if this Lease had not been terminated or if Landlord had not entered or re-entered, as aforesaid, and whether the Premises be relet or remain vacant, in whole or in part, or for a period less than the remainder of the Term, and for the whole thereof, but in the event the Premises be relet by Landlord, Tenant shall be entitled to a credit in the net amount of rent and other charges received by Landlord in reletting, after deduction of all reasonable expenses incurred in reletting the Premises (including, without limitation, remodeling costs, brokerage fees and the like (at market rates)), and in collecting the rent in connection therewith, in the following manner:

Amounts received by Landlord after reletting shall first be applied against such Landlord’s expenses, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease (Tenant’s liability prior to any such reletting and such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such expenses have been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would fall due under this Lease, and only the net amount thereof shall be payable by Tenant. Further, amounts received by Landlord from such reletting for any period shall be credited only against obligations of Tenant allocable to such period, and shall not be credited against obligations of Tenant hereunder accruing subsequent or prior to such period; nor shall any credit of any kind be due for any period after the date when the term of this Lease is scheduled to expire according to its terms.

(d) (i) At any time after such termination and whether or not Landlord shall have collected any damages as aforesaid, as liquidated final damages and in lieu of all other damages beyond the date of notice from Landlord to Tenant, at Landlord’s election, Tenant shall promptly pay to Landlord (in addition to any damages collected or due from Tenant from any period prior to such notice and all expenses which Landlord may have incurred with respect to the collection of such damages), such a sum as at the time of such notice represents the amount of the excess, if any, of (a) the discounted present value, at a discount rate of 6%, of the Annual Fixed Rent, Additional Rent and other charges which would have been payable by Tenant under this Lease for the remainder of the Lease Term if the Lease terms had been fully complied with by Tenant, over and above (b) the discounted present value, at a discount rate of 6%, of the Annual Fixed Rent, Additional Rent and other charges that would be received by Landlord if the Premises were re- leased at the time of such notice for the remainder of the Lease Term at the fair market value (including provisions regarding periodic increases in Annual Fixed Rent if such are applicable) prevailing at the time of such notice as reasonably determined by Landlord.

(d) (ii) For the purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with the immediately preceding paragraph, the total fixed rent and regularly scheduled payments of Additional Rent shall be computed by assuming that Tenant’s share of excess taxes, Tenant’s share of excess operating costs and Tenant’s share of excess electrical costs would be, for the balance of the unexpired Term from the date of such notice, the amount thereof (if any) for the immediately preceding annual period payable by Tenant to Landlord.

(e) In case of any Event of Default, re-entry, dispossession by summary proceedings or otherwise, Landlord may (i) re-let the Premises or any part or parts thereof, either in the name of Landlord or otherwise, 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 of this Lease and may grant concessions or free rent to the extent that Landlord considers advisable or necessary to re-let the same and (ii) may make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary for the purpose of reletting the Premises; and the making of such alterations, repairs and decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall in no event be liable in any way whatsoever for failure to re-let the Premises, or, in the event that the Premises are re-let, for failure to collect the rent under re-letting. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being evicted or dispossessed, or in the event of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease.

(f) The specified remedies to which Landlord may resort hereunder are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be entitled lawfully, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not

herein provided for. Further, nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for 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.

(g) In lieu of any other damages or indemnity and in lieu of the recovery by Landlord of all sums payable under all the foregoing provisions of this Section 7.1, Landlord may elect to collect from Tenant, by notice to Tenant, at any time after this Lease is terminated under any of the provisions contained in this Article VII or otherwise terminated by breach of any obligation of Tenant and before full recovery under such foregoing provisions, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the sum of the Annual Fixed Rent and all Additional Rent payable for the twelve (12) months ended next prior to such termination plus the amount of Annual Fixed Rent and Additional Rent of any kind accrued and unpaid at the time of such election plus any and all expenses which the Landlord may have incurred for and with respect of the collection of any of such rent.

7.2 LANDLORD’S DEFAULT. Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord shall have failed to (i) make any payments to Tenant within the time period set forth under this Lease and such failure continues for ten (10) days after notice thereof from Tenant to Landlord, or (ii) perform such non-monetary obligations within thirty (30) days after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation; provided, however, that if such failure is of such a nature that Landlord cannot reasonably remedy the same within such thirty (30) day period and Landlord has commenced such cure within such thirty (30) day period, Landlord shall have such additional time as is reasonably required to cure any such default provided Landlord diligently and continually prosecutes such cure to completion. Except as specifically set forth in Section 8.17(B), the Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against the Landlord from rent thereafter due and payable, but shall look solely to the Landlord for satisfaction of such claim.

ARTICLE VIII

8.1 EXTRA HAZARDOUS USE. Tenant covenants and agrees that Tenant will not do or permit anything to be done in or upon the Premises, or bring in anything or keep anything therein, which shall increase the rate of insurance on the Premises or on the Building above the standard rate applicable to premises being occupied for the use to which Tenant has agreed to devote the Premises; and Tenant further agrees that, in the event that Tenant shall do any of the foregoing, Tenant will promptly pay to Landlord, within thirty (30) days of notice thereof together with reasonable evidence of any such increase, any such increase resulting therefrom, which shall be due and payable as Additional Rent thereunder.

8.2 WAIVER. Failure on the part of Landlord or Tenant to complain of any action or non-action on the part of the other, no matter how long the same may continue, shall never be a waiver by Tenant or Landlord, respectively, of any of its rights hereunder. Further, no waiver at any time of any of the provisions hereof by Landlord or Tenant shall be construed as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions hereof shall not be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or Tenant to or of any action by the other requiring such consent or approval shall not be construed to waive or render unnecessary Landlord’s or Tenant’s consent or approval to or of subsequent similar act by the other.

No payment by Tenant or Landlord, or acceptance by Landlord or Tenant, of a lesser amount than shall be due from Tenant to Landlord, or Landlord to Tenant, as the case may be, shall be treated otherwise than as a payment on account. The acceptance by Landlord or Tenant of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord or Tenant may accept such check without prejudice to any other rights or remedies which Landlord or Tenant may have against the other.

8.3 CUMULATIVE REMEDIES. Except as expressly provided in this Lease, the specific remedies to which Landlord or Tenant 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 such party may be lawfully entitled in case of any breach or

threatened breach by Tenant or Landlord of any provisions of this Lease. In addition to the other remedies provided in this Lease, Landlord or Tenant 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.

8.4 QUIET ENJOYMENT. Tenant, subject to the terms and provisions of this Lease on payment of the rent and observing, keeping and performing all of the terms and provisions of this Lease on Tenant’s part to be observed, kept and performed, shall lawfully, peaceably and quietly have, hold, occupy and enjoy the Premises during the Term (exclusive of any period during which Tenant is holding over after the termination or expiration of this Lease without the consent of Landlord), without hindrance or ejection by Landlord or any persons lawfully claiming under Landlord to have title to the Premises superior to Tenant, subject, however, to the terms of this Lease; the foregoing covenant of quiet enjoyment is in lieu of any other covenant, express or implied; and it is understood and agreed that this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and Landlord’s successors, including ground or master lessees, only with respect to breaches occurring during Landlord’s or Landlord’s successors’ respective ownership of Landlord’s interest hereunder, as the case may be.

Further, Tenant specifically agrees to look solely to Landlord’s then interest in the Building at the time owned, or in which Landlord holds an interest as ground lessee, for recovery of any judgment from Landlord; it being specifically agreed that neither Landlord (original or successor), nor any beneficiary of any trust of which any person holding Landlord’s interest is trustee, nor any member, manager, partner, director or stockholder, nor Landlord’s managing agent, shall ever be personally liable for any such judgment, or for the payment of any monetary obligation to Tenant. The provision contained in the foregoing sentence is not intended to, and shall not, limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord’s successors in interest, or any action not involving the personal liability of Landlord (original or successor), any successor trustee to the persons named herein as Landlord, or any beneficiary of any trust of which any person holding Landlord’s interest is trustee, or of any manager, member, partner, director or stockholder of Landlord or of Landlord’s managing agent to respond in monetary damages from Landlord’s assets other than Landlord’s interest aforesaid in the Building, but in no event shall Tenant have the right to terminate or cancel this Lease or to withhold rent or to set-off any claim or damages against rent as a result of any default by Landlord or breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the demised premises (constructive or actual) by Landlord continuing after notice to Landlord thereof and a reasonable opportunity for Landlord to cure the same. In no event shall Landlord ever be liable to Tenant for any indirect or consequential damages or loss of profits or the like. In the event that Landlord shall be determined to have acted unreasonably in withholding any consent or approval under this Lease, the sole recourse and remedy of Tenant in respect thereof shall be to specifically enforce Landlord’s obligation to grant such consent or approval, and in no event shall the Landlord be responsible for any damages of whatever nature in respect of its failure to give such consent or approval nor shall the same otherwise affect the obligations of Tenant under this Lease or act as any termination of this Lease.

8.5 NOTICE TO MORTGAGEE AND GROUND LESSOR. After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises as part of the mortgaged premises, or that it is the ground lessor under a lease with Landlord, as ground lessee, which includes the Premises as a part of the demised premises, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given to such holder or ground lessor, and the curing of any of Landlord’s defaults by such holder or ground lessor within a reasonable time thereafter shall be treated as performance by Landlord. For the purposes of this Section 8.5 or Section 8.15, the term “mortgage” includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest). Landlord represents that as of the date of this Lease that there is no mortgage or ground lease affecting the Building.

8.6 ASSIGNMENT OF RENTS. With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder, conditional in nature or otherwise, which assignment is made to the holder of a mortgage or ground lease on property which includes the Premises, Tenant agrees:

(a) That the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage or the ground lessor, shall never be treated as an assumption by such holder or ground lessor of any of the

obligations of Landlord hereunder, unless such holder, or ground lessor, shall, by notice sent to Tenant, specifically otherwise elect; and

(b) That, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlord’s obligations hereunder only upon foreclosure of such holder’s mortgage and the taking of possession of the Premises, or, in the case of a ground lessor, the assumption of Landlord’s position hereunder by such ground lessor.

In no event shall the acquisition of title to the Building and the land on which the same is located by a purchaser which, simultaneously therewith, leases the entire Building or such land back to the seller thereof be treated as an assumption by such purchaser-lessor, by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder subject to the provisions of Section 8.4 hereof. In any such event, this Lease shall be subject and subordinate to the lease to such purchaser provided that such purchaser agrees to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder and provided that Tenant agrees to attorn to such purchaser. For all purposes, such seller-lessee, and its successors in title, shall be the landlord hereunder unless and until Landlord’s position shall have been assumed by such purchaser-lessor.

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

8.8 BROKERAGE. (A) Tenant warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm, if any, designated in Section 1.1 hereof; and in the event any claim is made against the Landlord relative to dealings by Tenant with brokers other than the Brokers, if any, designated in Section 1.1 hereof, Tenant shall defend the claim against Landlord with counsel of Tenant’s selection first approved by Landlord (which approval will not be unreasonably withheld) and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim.

(B) Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm, if any, designated in Section 1.1 hereof; and in the event any claim is made against the Tenant relative to dealings by Landlord with brokers other than the Brokers, if any, designated in Section 1.1 hereof, Landlord shall defend the claim against Tenant with counsel of Landlord’s selection and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the Broker for the Original Term of this Lease, if any, designated in Section 1.1 hereof.

8.9 INVALIDITY OF PARTICULAR PROVISIONS. If any term or provision of this Lease, or the application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law.

8.10 PROVISIONS BINDING, ETC. The obligations of this Lease shall run with the land, and except as herein otherwise provided, the terms hereof shall be binding upon and shall inure to the benefit of the successors and assigns, respectively, of Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. Each term and each provision of this Lease to be performed by Tenant shall be construed to be both a covenant and a condition. The reference contained to successors and assigns of Tenant is not intended to constitute a consent to subletting or assignment by Tenant.

8.11 RECORDING. Tenant agrees not to record the within Lease, but each party hereto agrees, on the request of the other, to execute a so-called Notice of Lease or short form lease in form recordable and complying with applicable law and reasonably satisfactory to both Landlord’s and Tenant’s attorneys. In no event shall such

document set forth rent or other charges payable by Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease.

8.12 NOTICES. Whenever, by the terms of this Lease, any (unless otherwise specified herein) notice, claim, demand, consent or other communication shall or may be given either to Landlord or to Tenant, such notice shall be in writing and shall be sent by overnight commercial courier or by registered or certified mail postage or delivery charges prepaid, as the case may be:

If intended for Landlord, addressed to Landlord at the address set forth on the first page of this Lease (or to such other address or addresses as may from time to time hereafter be designated by Landlord by like notice) with a copy to Landlord, Attention: General Counsel.

If intended for Tenant, addressed to Tenant at the address set forth on the second page of this Lease Attention : Controller except that from and after the Commencement Date the address of Tenant shall be the Premises (or to such other address or addresses as may from time to time hereafter be designated by Tenant by like notice) with a copy to ▇▇▇▇ and ▇▇▇▇ LLP, ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇, Attention: ▇▇▇ ▇▇▇▇▇▇▇▇▇, Esq..

Except as otherwise provided herein, all such notices shall be effective when received; provided, that (i) if receipt is refused, notice shall be effective upon the first occasion that such receipt is refused or (ii) if the notice is unable to be delivered due to a change of address of which no notice was given, notice shall be effective upon the date such delivery was attempted.

Where provision is made for the attention of an individual or department, the notice shall be effective only if the wrapper in which such notice is sent is addressed to the attention of such individual or department.

Any notice given by an attorney on behalf of Landlord or Tenant or by Landlord’s managing agent shall be considered as given by Landlord or Tenant and shall be fully effective.

Time is of the essence with respect to any and all notices and periods for giving notice or taking any action thereto under this Lease.

8.13 WHEN LEASE BECOMES BINDING. Employees or agents of Landlord have no authority to make or agree to make a lease or any other agreement or undertaking in connection herewith. The submission of this document for examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant. All negotiations, considerations, representations and understandings between Landlord and Tenant are incorporated herein and may be modified or altered only by written agreement between Landlord and Tenant, and no act or omission of any employee or agent of Landlord or Tenant shall alter, change or modify any of the provisions hereof.

8.14 SECTION HEADINGS. The titles of the Articles throughout this Lease are for convenience and reference only, and the words contained therein shall in no way be held to explain, modify, amplify or aid in the interpretation, construction or meaning of the provisions of this Lease.

8.15 RIGHTS OF MORTGAGEE. This Lease shall be subject and subordinate to any mortgage now or hereafter on the Site or the Building, or both, and to each advance made or hereafter to be made under any mortgage, and to all renewals, modifications, consolidations, replacements and extensions thereof and all substitutions therefor provided that the holder of such mortgage agrees to recognize the rights of Tenant under this Lease (including the right to use and occupy the Premises) upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder. In confirmation of such subordination and recognition, Tenant shall execute and deliver promptly such instruments of subordination and recognition as such mortgagee may reasonably request subject to receipt of such instruments of recognition from such mortgagee as Tenant may reasonably request. In the event that any mortgagee or its respective successor in title shall succeed to the interest of Landlord, then, this Lease shall nevertheless continue in full force and effect and Tenant shall and

does hereby agree to attorn to such mortgagee or successor and to recognize such mortgagee or successor as its landlord. If any holder of a mortgage which includes the Premises, executed and recorded prior to the date of this Lease, shall so elect, this Lease and the rights of Tenant hereunder, shall be superior in right to the rights of such holder, with the same force and effect as if this Lease had been executed, delivered and recorded, or a statutory Notice hereof recorded, prior to the execution, delivery and recording of any such mortgage. The election of any such holder shall become effective upon either notice from such holder to Tenant in the same fashion as notices from Landlord to Tenant are to be given hereunder or by the recording in the appropriate registry or recorder’s office of an instrument in which such holder subordinates its rights under such mortgage to this Lease.

8.16 STATUS REPORTS AND FINANCIAL STATEMENTS. Recognizing that Landlord or Tenant may find it necessary to establish to potential or existing mortgagees, potential purchasers, ground lessors, permitted assignees or subtenants or the like, as applicable, or the like, the then current status of performance hereunder, Tenant or Landlord, on the request of the other made from time to time, will promptly furnish to Landlord, or any existing or potential holder of any mortgage encumbering the Premises, the Building, the Site and/or the Complex or any potential purchaser of the Premises, the Building, the Site and/or the Complex or to any permitted assignee or subtenant of the Premises or Building (each an “Interested Party”), a statement of the status of any matter pertaining to this Lease customarily provided in a so-called “estoppel certificate”, including, without limitation, acknowledgments that (or the extent to which) each party is in compliance with its obligations under the terms of this Lease. In addition, not more than once in any calendar year, Tenant shall deliver to Landlord, or any Interested Party designated by Landlord, financial statements of Tenant, as reasonably requested by Landlord, including, but not limited to financial statements for the past three (3) years. Any such status statement or financial statement delivered by Tenant pursuant to this Section 8.16 may be relied upon by any Interested Party.

8.17 SELF-HELP. (A) If an Event of Default then exists, 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 to the extent required to cure any such default. All sums so paid by Landlord (together with interest at the rate of two percentage points over the then prevailing prime rate in Boston as set by Fleet National Bank or its successor (but in no event greater than the maximum rate permitted by applicable law) and all costs and expenses in connection with the performance of any such act by Landlord, shall be deemed to be Additional Rent under this Lease and shall be payable to Landlord immediately on demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease.

(B) Landlord shall never be liable for any failure to make repairs which, under the provisions of this Lease, Landlord has undertaken to make unless:

(a) Tenant has given notice to Landlord of the need to make such repairs, or of a condition in the Building or in the Premises requiring any repair for which Landlord is responsible; and

(b) Landlord has failed to commence to make such repairs within a reasonable time after receipt of such notice.

In the event Landlord fails to make such repairs as are required of Landlord within thirty (30) days after written notice from Tenant to Landlord and to the holder of any mortgage on the Premises of which Landlord has given Tenant notice or of which Tenant has actual notice, specifying the nature of such repairs (or if such repairs are of the type which cannot be completed within thirty (30) days, then if Landlord or the holder of any such mortgage (at the option of such mortgagee) fails to (i) commence making such repairs within thirty (30) days after such written notice from Tenant and (ii) thereafter prosecute such repairs to completion with due diligence given the nature of such repairs), then thereafter at any time prior to Landlord’s or such mortgagee’s commencing such repairs or subsequent to Landlord or such mortgagee commencing such repairs if Landlord or such mortgagee has not prosecuted such repairs to completion with due diligence given the nature of such repairs, Tenant may, but need not, make such repairs to the extent required to remedy any such situation and charge the reasonable cost thereof to Landlord; provided, however, that in the case of emergency repairs (i) such notice by Tenant to Landlord and such mortgagee need not be in writing, and (ii) Tenant may make such emergency repairs and charge the reasonable cost thereof to

Landlord if either Landlord or such mortgagee has not made such emergency repairs within a reasonable time after such notice. However, in no event shall Tenant have the right to offset against, withhold or deduct from Annual Fixed Rent or additional rent payable under this Lease for any reason relating to this Section.

8.18 HOLDING OVER. Any holding over by Tenant after the expiration of the term of this Lease shall be treated as a tenancy at sufferance and shall be on the terms and conditions as set forth in this Lease, as far as applicable except that Tenant shall pay as a use and occupancy charge an amount equal to the greater of (x) 150% of the Annual Fixed Rent and Additional Rent calculated (on a daily basis) at the highest rate payable under the terms of this Lease, or (y) the fair market rental value of the Premises, in each case for the period measured from the day on which Tenant’s hold-over commences and terminating on the day on which Tenant vacates the Premises. In addition, Tenant shall save Landlord, its agents and employees harmless and will exonerate, defend and indemnify Landlord, its agents and employees from and against any and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the term of this Lease. Nothing in the foregoing nor any other term or provision of this Lease shall be deemed to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. All property which remains in the Building or the Premises after the expiration or termination of this Lease shall be conclusively deemed to be abandoned and may either be retained by Landlord as its property or sold or otherwise disposed of in such manner as Landlord may see fit. If any part thereof shall be sold, then Landlord may receive the proceeds of such sale and apply the same, at its option against the expenses of the sale, the cost of moving and storage, any arrears of rent or other charges payable hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under this Lease and at law and in equity, with the balance, if any, paid to Tenant.

8.19 NON-SUBROGATION. Any insurance carried by either party with respect to the Premises or property therein or occurrences thereon shall, if it can be so written without additional premium or with an additional premium which the other party agrees to pay, include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any rights of recovery against the other for injury or loss due to hazards covered by such insurance (or which would have been covered had such party carried the insurance required to be carried by it under the Lease) to the extent of the indemnification received thereunder. This waiver of rights by Tenant shall apply to, and be for the benefit of, Landlord’s managing agent.

8.20 EXTENSION OPTION. (A) On the conditions (which conditions Landlord may waive by written notice to Tenant) that at the time of exercise of the option to extend and at the commencement date of the extension option period (i) there exists no Event of Default (defined in Section 7.1), (ii) this Lease is still in full force and effect, and (iii) Tenant has neither assigned this Lease nor sublet the Premises (except for an assignment or subletting permitted under Section 5.6.1 hereof), Tenant shall have the right to extend the Term hereof upon all the same terms, conditions, covenants and agreements herein contained (except for the Annual Fixed Rent which shall be adjusted during the option period as herein below set forth) for one (1) period of three (3) years as hereinafter set forth. The option period is sometimes herein referred to as the “Extended Term”. Notwithstanding any implication to the contrary Landlord has no obligation to make any additional payment to Tenant in respect of any construction allowance or the like or to perform any work to the Premises as a result of the exercise by Tenant of such option.

(B) If Tenant desires to exercise its option to extend the Term, then Tenant shall give notice (“Exercise Notice”) to Landlord, not earlier than twelve (12) months nor later than nine (9) months prior to the expiration of the then Term, exercising such option to extend. Promptly after Landlord’s receipt of the Exercise Notice, Landlord shall provide Landlord’s quotation to Tenant of a proposed annual rent for the Extended Term (“Landlord’s Rent Quotation”). If at the expiration of thirty (30) days after the date when Landlord provides such quotation to Tenant (the “Negotiation Period”), Landlord and Tenant have not reached agreement on a determination of an annual rental for the Extended Term and executed a written instrument extending the Term of this Lease pursuant to such agreement, then Tenant shall have the right, for thirty (30) days following the expiration of the Negotiation Period, to make a request to Landlord for a broker determination (the “Broker Determination”) of the Prevailing Market Rent (as defined in Exhibit E) for the Extended Term, which Broker Determination shall be made in the manner set forth in Exhibit E. If Tenant timely shall have requested the Broker Determination, then the Annual Fixed Rent for the Extended Term shall be the greater of (a) 95% of the Prevailing Market Rent as determined by the Broker

Determination or (b) the Annual Fixed Rent in effect during the last twelve (12) month period of the Lease Term immediately prior to the Extended Term. If Tenant does not timely request the Broker Determination, then Annual Fixed Rent during the Extended Term shall be equal to the greater of (a) Landlord’s Rent Quotation or (b) the Annual Fixed Rent in effect during the last twelve (12) month period of the Lease Term immediately prior to such Extended Term.

(C) Upon the giving of the Exercise Notice by Tenant to Landlord exercising Tenant’s option to extend the Lease Term in accordance with the provisions of Section B above, then this Lease and the Lease Term hereof shall automatically be deemed extended, for the Extended Term, without the necessity for the execution of any additional documents, except that Landlord and Tenant agree to enter into an instrument in writing setting forth the Annual Fixed Rent for the Extended Term as determined in the relevant manner set forth in this Section 8.20; and in such event all references herein to the Lease Term or the term of this Lease shall be construed as referring to the Lease Term, as so extended, unless the context clearly otherwise requires, and except that there shall be no further option to extend the Lease Term. Notwithstanding anything contained herein to the contrary, in no event shall the Lease Term hereof be extended for more than three (3) years after the expiration of the Original Lease Term.

8.21 SECURITY DEPOSIT. (A) Concurrently with the execution of this Lease, Tenant shall pay to Landlord a security deposit in the amount of Two Hundred Seventy Nine Thousand Dollars ($279,000.00) and Landlord shall hold the same, throughout the Term of this Lease (including the Extended Term, if applicable), unless sooner returned to Tenant as provided in this Section 8.21, as security for the performance by Tenant of all obligations on the part of Tenant to be performed under this Lease. Such deposit shall be in the form of an irrevocable, unconditional, negotiable letter of credit (the “Letter of Credit”). The Letter of Credit shall (i) be issued by and drawn on a bank reasonably approved by Landlord and at a minimum having a corporate credit rating from Standard and Poor’s Professional Rating Service of BBB- or a comparable minimum rating from ▇▇▇▇▇’▇ Professional Rating Service as of the Commencement Date, (ii) be in a form reasonably acceptable to Landlord, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord that pursuant to the terms of this Lease, Landlord is entitled to apply such Letter of Credit and the proceeds thereof to an Event of Default of Tenant under this Lease, (iv) permit transfers at any time with reasonable or no charge and (v) permit presentment in Boston, Massachusetts. Any such Letter of Credit shall be for a term of two (2) years (or for one (1) year if the issuer thereof regularly and customarily only issues letters of credit for a maximum term of one (1) year) and shall in either case provide for automatic renewals through the date which is thirty (30) days subsequent to the scheduled expiration of this Lease (as the same may be extended) or if the issuer will not grant automatic renewals, the Letter of Credit shall be renewed by Tenant each year and each such renewal shall be delivered to and received by Landlord not later than thirty (30) days before the expiration of the then current Letter of Credit (herein called a “Renewal Presentation Date”). In the event of a failure to so deliver any such renewal Letter of Credit on or before the applicable Renewal Presentation Date, Landlord shall be entitled to present the then existing Letter of Credit for payment and to receive the proceeds thereof, which proceeds shall be held as Tenant’s security deposit, subject to the terms of this Section 8.21. Upon the occurrence of any Event of Default, Landlord shall have the right from time to time without prejudice to any other remedy Landlord may have on account thereof, to draw on all or any portion of such deposit held as a Letter of Credit and to apply the proceeds of such Letter of Credit or any cash held as such deposit (in lieu of the original Letter of Credit), or any part thereof, to Landlord’s damages arising from such Event of Default on the part of Tenant under the terms of this Lease. If Landlord so applies all or any portion of such deposit, Tenant shall within seven (7) days after notice from Landlord deposit cash with Landlord or deliver a substitute Letter of Credit in an amount sufficient to restore such deposit or initial Letter of Credit to the full amount stated in this Section 8.21. While Landlord holds any cash deposit Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the same with Landlord’s other funds. Neither the holder of a mortgage nor the Landlord in a ground lease on property which includes the Premises shall ever be responsible to Tenant for the return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been received in hand by such holder or ground Landlord.

(B) Landlord shall return a One Hundred Thirty Nine Thousand Five Hundred Dollars ($139,500.00) portion of such deposit to Tenant so that the remainder of such deposit shall be One Hundred Thirty Nine Thousand Five Hundred Dollars ($139,500.00) (or if such deposit is in the form of a Letter of Credit, Landlord shall exchange the Letter of Credit for a Letter of Credit delivered by Tenant which reduces the amount secured by the Letter of Credit by the amount stated hereinabove) on the first day of the twenty-fifth (25^th) month of the Lease Term if (i) Tenant is not

then in default under the terms of this Lease without the benefit of notice or grace, and (ii) Landlord has not applied such deposit or any portion thereof to Landlord’s damages arising from any default on the part of Tenant, whether or not Tenant has restored the amount so applied by Landlord.

(C) Tenant not then being in default and having performed all of its obligations under this Lease, including the payment of all Annual Fixed Rent, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied or returned in accordance with the terms of this Section 8.21, to Tenant on the expiration or earlier termination of the term of this Lease (as the same may have been extended) and Tenant’s surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such time.

8.22 LATE PAYMENT. If Landlord shall not have received any payment or installment of Annual Fixed Rent or Additional Rent (the “Outstanding Amount”) on or before the date on which the same first becomes payable under this Lease (the “Due Date”), the amount of such payment or installment shall incur a late charge equal to the sum of: (a) five percent (5%) of the Outstanding Amount for administration and bookkeeping costs associated with the late payment and (b) interest on the Outstanding Amount from the Due Date through and including the date such payment or installment is received by Landlord, at a rate equal to the lesser of (i) the rate announced by Fleet National Bank (or its successor) from time to time as its prime or base rate (or if such rate is no longer available, a comparable rate reasonably selected by Landlord), plus two percent (2%), or (ii) the maximum applicable legal rate, if any (the “Late Charge Rate”). Such interest shall be deemed Additional Rent and shall be paid by Tenant to Landlord upon demand. If Tenant shall not have received any payment from Landlord when due, the amount of such payment shall incur a late charge equal to the Late Charge Rate.

8.23 LANDLORD’S AND TENANT’S PAYMENTS. (A) Each and every payment and expenditure, other than Annual Fixed Rent, shall be deemed to be Additional Rent hereunder, whether or not the provisions requiring payment of such amounts specifically so state, and shall be payable, unless otherwise provided in this Lease, within thirty (30) days after written demand by Landlord, and in the case of the non-payment of any such amount, Landlord shall have, in addition to all of its other rights and remedies, all the rights and remedies available to Landlord hereunder or by law in the case of non-payment of Annual Fixed Rent. Unless expressly otherwise provided in this Lease, the performance and observance by Tenant of all the terms, covenants and conditions of this Lease to be performed and observed by Tenant shall be at Tenant’s sole cost and expense.

(B) Unless otherwise specifically set forth herein, all payments required to be made by Landlord to Tenant shall be paid within thirty (30) days after request from Tenant.

8.24 WAIVER OF TRIAL BY JURY. Tenant and Landlord hereby waive any right to trial by jury in any action, proceeding or counterclaim brought by either Landlord or Tenant on any matters whatsoever arising out of or any way connected with this Lease, the relationship of the Landlord and the Tenant, the Tenant’s use or occupancy of the Premises and/or any claim of injury or damage, including but not limited to, any summary process eviction action.

8.25 TENANT’S SIGNAGE. Tenant shall have the right to (i) install a sign on the lobby level entrance to the Building to the right of the building entrance in the landscaped area immediately adjacent to the Building (the “Building Entrance Sign”) which sign (exclusive of any monument or ballasts) shall not exceed 5’ in width and 2’ in height and shall fall below the window line of the Building (inclusive of any monument or ballasts) and (ii) erect an exterior sign on the Building (the “Building Signage”) containing Tenant’s name in a location first approved by Landlord provided that (a) Tenant complies with all applicable “Governmental Requirements” and obtains all permits, approvals, consents and the like required by the Governmental Requirements, (b) the graphics, design, proportions, lighting component and color of such signage shall be subject to the prior approval of Landlord and shall be further subject to the requirements of the Town of Lexington Zoning By-Law and any other applicable laws, and (c) Tenant shall be solely responsible for all costs and expenses regarding the Building Signage and the Building Entrance Sign including, without limitation, fabrication costs, design costs, installation costs and all application, permit and approval costs. Landlord shall, at its expense, install the VistaPrint name on the existing free standing sign located at the Hayden Avenue entrance to the Site (the “Hayden Avenue Entrance Sign”). Tenant acknowledges that rights to the Hayden Avenue Entrance Sign are non-exclusive. In addition, Landlord shall remove, at Landlord’s sole cost and expense, the signs of any prior tenant on or before thirty (30) days after the Commencement Date. Landlord agrees to cooperate with Tenant regarding Tenant’s obtaining approvals of the Building Entrance Sign and the Building Signage including without limitation, joining in any applications for any permits, approvals or

certificates from any governmental authorities required to be obtained by Tenant, and shall sign such applications reasonably promptly after request by Tenant provided that (i) the provisions of the Applicable Legal Requirement shall require that Landlord join in such application, and (ii) Landlord shall not be required to expend any monies, assume any costs or expenses or undertake any liability. The rights set forth in this Section 8.25 shall not be available to any subtenant and in no event shall any such signage identify more than one (1) occupant of the Building. Upon the expiration or earlier termination of the Lease Term, Tenant, at its expense shall remove the Building Signage and restore the affected area of the Building to the condition immediately prior to such installation.

8.26 RECIPROCAL LITIGATION COSTS. In the event of any litigation between Landlord and Tenant, the unsuccessful party as determined by a court of competent jurisdiction shall reimburse the successful party for all reasonable legal fees and expenses incurred by the successful party in prosecuting or defending any such action.

8.27 FORCE MAJEURE. Except for Landlord’s or Tenant’s payment obligations, or as otherwise provided under this Lease, if either party is delayed in performing its obligations hereunder, by reason of delay or stoppage due to governmental regulation; strikes, lockouts, acts of God, acts of war, terrorist acts, civil commotions, unusual scarcity of or inability to obtain labor or materials, labor difficulties, casualty or other causes beyond the reasonable control of Landlord or Tenant (as the case may be), or attributable to Landlord’s or Tenant’s action or inaction (as the case may be) the time for Landlord’s or Tenant’s performance shall be extended for the period of any such delay.

8.28 REPRESENTATION OF LANDLORD REGARDING CERTAIN ENCUMBRANCES. Landlord represents to Tenant that as of the date hereof there is no mortgage or ground lease encumbering the Complex and there are no space leases which effect the Premises.

Landlord agrees to use due diligence to obtain from CIGNA and record a discharge of (i) above and to record an affidavit from Landlord with respect to (ii), and (iv) above stating that such leases are no longer in effect. The Highland Lease relates to ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ and is still in full force and effect, however, Landlord represents that such tenant does not have any rights with respect to the Premises. Further, Landlord agrees to indemnify Tenant from and against all claims and liability arising from such Matters of Record (except for the Highland Lease).

8.29 GOVERNING LAW. This Lease shall be governed exclusively by the provisions hereof and by the law of the Commonwealth of Massachusetts, as the same may from time to time exist.
