Notwithstanding the foregoing to the contrary, Landlord hereby agrees to demise the Premises from the immediately adjacent and currently vacant space and to cut an opening in the exterior wall of the building and install one 8'x8' overhead roll-up door in that portion, of the Premises identified as the "new loading dock area" on Exhibit B to this Lease.

It is also agreed and understood that Landlord shall not be deemed to be unreasonable in denying its consent to alterations, additions and improvements to the Premises which affect "Base Building Systems" (as said term is hereafter defined). - 6 - 11 As used herein, the term "Base Building Systems" shall mean (i) any mechanical, electrical or plumbing system or component of the Building (including the Premises) (ii) the exterior of the Building (iii) the Building HVAC distribution system (iii) any fire safety prevention/suppression system and (iv) any structural element or component of the Building.

(c) Notice is hereby given that Landlord shall not be liable for any labor or materials furnished or to be furnished to Tenant upon credit, and that no mechanic's or other lien for any such labor or materials shall attach to or affect the reversion or other estate or interest of Landlord in and to the Premises. Whenever and as often as any mechanic's lien shall have been filed against the Premises based upon any act or interest of Tenant or of anyone claiming through Tenant, Tenant shall forthwith take such actions by bonding, deposit or payment as will remove or satisfy the lien. (d) All of the Tenant's alterations, 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 damage the Property or interfere with Building construction or operation and, except for installation of furnishings, shall be performed by Landlord's general contractor or, at Landlord's election, by contractors or workmen first approved by Landlord. Installation and moving of furnishings, equipment and the like shall be performed only with labor compatible with that being employed by Landlord for work in or to the Building and not to employ or permit the use of any labor or otherwise take any action which might result in a labor dispute involving personnel providing services in the Building.

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 Property and immediately to discharge any such liens which may so attach and, at the request of Landlord to deliver to Landlord security satisfactory to Landlord against liens arising out of the furnishing of such labor and material. Upon completion of any work done on the Premises by Tenant, its agents, employees, or independent contractors, Tenant shall promptly deliver to Landlord original lien releases and waivers executed by each contractor, subcontractor, supplier, materialmen, architect, engineer or other party which furnished labor, materials or other services in connection with such work and pursuant to which all liens, claims and other rights of such party with respect to labor, material or services furnished in connection with such work are unconditionally released and waived. Tenant shall pay within fourteen (14) days after being billed therefor by Landlord, as an additional charge hereunder, one hundred percent (100%) of any increase in real estate taxes on the Property not otherwise billed to Tenant which shall, at any time after commencement of the Term, result from any alteration, addition or improvement to the Premises made by or on behalf of Tenant (including Tenant's original installation and Tenant's subsequent alterations, additions, substitutions and improvements), whether done prior to or after the commencement of the Term of this Lease. (e) In connection with the performance of any alterations,. improvements, changes or additions to the Premises as contemplated by Article IV or Section 5.2 of this Lease, in the event that any such improvement, alteration, change or addition to the Premises to be performed by Tenant ("Work') affects so-called "Base Building Building Systems" and to the extent that such Work is not performed by Landlord or a general contractor employed directly by Landlord, Tenant hereby agrees to use the services of a construction management firm designated by Landlord to oversee, coordinate and review all aspects of any such Work. The cost and expense of the services of such construction manager shall be borne by Tenant but only to the extent that such costs and expenses are comparable to and competitive with the costs and expenses charged by other firms engaged in - 8 - 13 construction management and oversight services in the general geographic location of the Building for services of a similar scope and type.

(a) Tenant covenants and agrees that whether voluntarily, involuntarily, by operation of law or otherwise, neither this Lease nor the term and estate hereby granted, nor any interest herein or therein, will be assigned, mortgaged, pledged, encumbered or otherwise transferred and that neither the Premises nor any part thereof will be encumbered in any manner by reason of any act or omission on the part of Tenant, or used or occupied, by anyone other than Tenant, or for any use or purpose other than a Permitted Use, or be sublet (which term, without limitation, shall include granting of concessions, licenses and the like) in whole or in part, or be offered or advertised for assignment or subletting. (b) The provisions of paragraph (a) of this Section shall apply to a transfer (by one or more transfers) of a majority of the stock or partnership interests, or other evidences of ownership of Tenant as if such transfer were an assignment of this Lease; but such provisions shall not apply to transactions with an entity into or with which Tenant is merged or consolidated or to which substantially all of Tenant's assets are transferred or to any entity which controls or is controlled by Tenant or is under common control with Tenant, provided that in any of such events (i) the successor to Tenant has a net worth computed in accordance with generally accepted accounting principles at least equal to the net worth of Tenant immediately prior to such merger, consolidation or transfer, (ii) proof satisfactory to Landlord of such net worth shall have been delivered to Landlord at least 10 days prior TO the effective date of any such transaction, and (iii) the assignee agrees directly with Landlord, by written instrument in form satisfactory to Landlord, to be bound by all the obligations of Tenant hereunder including, without limitation, the covenant against further assignment or subletting.

Notwithstanding the foregoing, Landlord may elect to take action hereunder immediately and without notice to Tenant if Landlord reasonably believes an emergency to exist. 7.3 FLOOR LOAD - HEAVY MACHINERY. (a) Tenant shall not place a load upon any floor in the Premises exceeding the floor load per square foot of area which such floor was designed to carry and which is allowed by law. Landlord reserves the right to prescribe the weight and position of all business machines and mechanical equipment, including safes, which shall be placed so as to distribute the weight. Business machines and mechanical equipment shall be placed and maintained by Tenant at Tenant's expense in settings sufficient, in Landlord's judgment, to absorb and prevent vibration, noise and annoyance. Tenant shall not move any safe, heavy machinery, heavy equipment, freight, bulky matter or fixtures into or out of the Building without Landlord's prior consent, which consent may include a requirement to provide insurance, naming Landlord as an insured, in such amounts as Landlord may deem reasonable. (b) If such safe, machinery, equipment, freight, bulky matter or fixtures requires special handling, Tenant agrees to employ only persons holding a Master Rigger's License to do such work, and that all work in connection therewith shall comply with applicable laws and regulations. Any such moving shall be at the sole risk and hazard of Tenant, and Tenant will exonerate, indemnity and save Landlord harmless against and from any liability, loss, injury, claim or suit resulting directly or indirectly from such moving. 7.4 BUILDING SERVICES. (a) Landlord shall also provide: (i) Cold water (at temperatures supplied by the Town of Chelmsford) for drinking, lavatory and toilet purposes. If Tenant uses water for any purpose other than for ordinary lavatory and drinking purposes, Landlord may assess a reasonable charge for the additional water so used, or install a water meter and thereby measure Tenant's water consumption for all purposes. In the latter event, Tenant shall pay the cost of the meter and the cost of installation thereof and - 12 - 17 shall keep such meter and installation equipment in good working order and repair. Tenant agrees to pay for water consumed, as shown on such meter, together with the sewer charge based on such meter charges, as and when bills are rendered, and in default in making such payment Landlord may pay such charges and collect the same from Tenant as an additional charge. (ii) Access to the Premises twenty-four hours per day, subject to reasonable security restrictions and restrictions based on emergency conditions and all other applicable provisions of this Lease. (b) Landlord reserves the right to curtail, suspend, interrupt and/or stop the supply of water, sewage, electrical current, cleaning, and other services, and to curtail, suspend, interrupt and/or stop use of entrances and/or lobbies serving access to the Building, without thereby incurring any liability to Tenant, when necessary by reason of accident or emergency, or for repairs, alterations, replacements or improvements in the judgment of Landlord desirable or necessary, or when prevented from supplying such services or use by strikes, lockouts, difficulty in obtaining materials, accidents or any other cause beyond Landlord's control, or by laws, orders or inability, by exercise of reasonable diligence, to obtain electricity, water, gas, steam, coal, oil or other suitable fuel or power. No diminution or abatement of rent or other compensation, nor any direct, indirect or consequential damages shall or will be claimed by Tenant as a result of, nor shall this Lease or any of the obligations of Tenant be affected or reduced by reason of, any such interruption, curtailment, suspension or stoppage in the furnishing of the foregoing services or use, irrespective of the cause thereof. Failure or omission on the part of Landlord to furnish any of the foregoing services or use shall not be construed as an eviction of Tenant, actual or constructive, nor entitle Tenant to an abatement of rent, nor to render the Landlord liable in damages, nor release Tenant from prompt fulfillment of any of its covenants under this Lease. 7.5 ELECTRICITY. (a) Landlord shall permit Landlord's existing wires, pipes, risers, conduits and other electrical equipment of Landlord to be used for the purpose of providing electrical service to the Premises. Tenant covenants and agrees that its electrical usage and consumption will not disproportionately "siphon off" electrical service necessary for other tenants of the Building and that its total connected load will not exceed the maximum load from time to time permitted by applicable governmental regulations nor the design criteria of the existing Building electrical capacity. -13- 18 Landlord shall not in any way be liable or responsible to Tenant for any loss or damage or expense which Tenant may sustain or incur if, during the Term of this Lease, either the quantity or character of electric current is changed or electric current is no longer available or suitable for Tenant's requirements due to a factor or cause beyond Landlord's control. Tenant shall purchase and install all lamps, tubes, bulbs, starters and ballasts. Tenant shall pay all charges for electricity, gas and other utilities used or consumed in the Premises. Tenant shall bear the cost of repair and maintenance of any electric or gas meter used or to be installed in (or serving) the Premises. (b) In order to insure that the foregoing requirements are not exceeded and to avert possible adverse affect on the Building's electrical system, Tenant shall not, without Landlord's prior consent, connect any fixtures, appliances or equipment to the Building's electrical distribution system, which operates on a voltage in excess of 120 volts nominal. If Landlord shall consent to the connection of any such fixtures, appliances or equipment, all additional risers or other electrical facilities or equipment required therefor shall be provided by Landlord and the cost thereof shall be paid by tenant upon Landlord's demand as Additional Rent. From time to time during the Term of this Lease, Landlord shall have the right to have an electrical consultant selected by Landlord make a survey of Tenant's electric usage, the result of which shall be conclusive and binding upon Landlord and Tenant. In the event that such survey shows that Tenant has exceeded the requirements set forth in paragraph (a), in addition to any other rights Landlord may have hereunder, Tenant shall, upon demand, reimburse Landlord for the costs of such survey. (c) Electricity and Gas Consumption. (i) Electricity and Natural Gas used and consummed in the Premises is measured by a single gas meter (the "Existing Gas Meter") and a single Electric Meter (the "Existing Electric Meter"). In addition to measuring consumption of Natural Gas and Electricity in the Premises, the Existing Gas Meter and Existing Electric Meter measure consumption of those utilities used and consumed in a portion of the Building which is immediately adjacent to the Premises and comprised of 13,619 rentable square feet (the "Adjacent Space"). The Adjacent Space is presently vacant and unoccupied and is not a portion of the Premises demised to Tenant under this Lease. The provisions of this paragraph 7.5(c) are intended to allocate certain responsibilities as to the payment of electricity and natural gas costs and expenses between Landlord (with respect to the Adjacent Space) and -14- 19 Tenant (with respect to the Premises) as measured by the Existing Gas Meter and the Existing Electric Meter. (ii) Tenant hereby acknowledges that the Tenant is the current named billing party with respect to the Existing Gas Meter and the Existing Electricity Meter. Tenant hereby acknowleges and agrees that subject to the terms and provisions hereafter set forth and until receipt of written notice from the Landlord to the contrary, all electricity and natural gas used and consumed in the Adjacent Space shall be provided through the Existing Gas Meter and the Existing Electric Meter with the allocation of expenses resulting from such meters between Landlord and Tenant as hereafter provided. Landlord and Tenant hereby acknowledge and agree that the aggregate per square foot cost of providing natural gas and electric service to the Adjacent Space is $0.20 per rentable square foot contained in the Adjacent Space per annum. (hereafter the "Per Square Foot Utility Cost"). The Per Square Foot Utility Cost is based upon the assumption that the Adjacent Space is vacant and unoccupied and is comprised of $0.12 per rentable square foot per annum with respect to electricity and $0.08 per rentable square foot per annum with respect to natural gas. Until further written notice from Landlord as hereafter set forth, Tenant shall be responsible for payment of all costs and expenses for gas and electricity billed to the Existing Electric Meter and the Existing Gas Meter for such time as the Existing Electric Meter and/or the Existing Gas Meter shall remain in Tenant's name. In order to reimburse Tenant for the cost of electricity and gas used and consumed in the Adjacent Space, Landlord shall pay Tenant an amount (the "Landlord's Utility Cost") equal to the number of rentable square feet contained in the Adjacent Space which shall from time to time be vacant (as designated by Landlord in a "Landlord's Utility Statement" as hereafter defined) multiplied by the Per Square Foot Utility Cost. Tenant shall from time to time, but not more often than once every three full calendar months while all or any portion of the Adjacent Space shall remain unoccupied (or until further notice from Landlord) invoice Landlord for the Landlord's Utility Cost attributable to the three full calendar month period setting forth the number of of such invoice (provided that the LST, such invoice shall be applicable only to the three full calendar month period immediately following the Commencement Date hereunder). Upon the written request of Tenant, or at any time at the Landlord's election, Landlord shall provide Tenant with a written calculation of the Landlord's Utility Costs applicable to any such three full-calendar month period setting forth the number of rentable square feet of the Adjacent Space which was -15- 20 unoccupied during such three month period and the actual number of days of vacancy ("Landlord's Utility Statement"). Landlord's Utility Statement shall be conclusive and binding upon Landlord and Tenant. At Landlord's option, Landlord shall be entitled to offset Landlord's Utility Costs against and apply amounts owing to Tenant hereunder against obligations of Tenant to Landlord under this Lease. Any failure by Tenant to pay amounts due and owing to the applicable utilities for gas and electricity billed to the Existing Gas Meter and/or the Existing Electric Meter shall entitle Landlord to the same rights and remedies against Tenant as Landlord has for a failure by Tenant to pay Basic Rent when due under this Lease. (iii) Notwithstanding the terms and provisions contained in paragraphs (i) and (ii) of this paragraph (c) to the contrary, at such time as Landlord shall procure a tenant to occupy all or any portion of the Adjacent Space, Landlord's obligation to pay Landlord's Utility Costs with respect to the portion of the Adjacent Space occupied by such third party shall cease and come to an end. At Landlord's option, Landlord shall be entitled to continue paying Landlord's Utility Cost with respect to any portion of the Adjacent Space which would then remain unoccupied based upon the number of rentable square feet contained in the Adjacent Space as shall then be unoccupied and the provisions of paragraphs (i) and (ii) of this paragraph (c) shall remain in force and effect and shall be applicable to such portions of the Adjacent Space as remain vacant. (iv) Tenant hereby acknowledges and agrees, and Landlord hereby reserves unto Landlord the right, exercisable by Landlord at any time and from time to time during the Term of this Lease to cause the Existing Electric Meter and the Existing Gas Meter (or either of them) to be placed in Landlord's name for billing purposes. In the event Landlord shall elect to implement the procedure described in the first sentence of this paragraph (iv), Landlord shall provide Tenant with written notice of such election and Tenant hereby agrees to execute such documents and instruments as may be required in order to effect a change of the named billing party on the Existing Electric Meter and the Existing Gas Meter (or either of them) to Landlord's name. The change of named party provided herein shall be deemed effective as of the date such change is made effective by the applicable utility (the "Change Date"). Tenant shall be responsible for all bills for the applicable utility being changed to Landlord's name prior to the Change Date. From and after the Change Date, Landlord shall have the right to cause electricity and natural gas used and consummed in the Premises to be check-metered off of -16- 21 the Existing Gas Meter and/or the Existing Electric Meter, as applicable. As an additional charge hereunder, Tenant shall reimburse Landlord for the cost of electricty and/or gas used and consummed in the Premises as measured by the applicable check meter within 15 days after being billed therefor by Landlord. Landlord shall have the right to collect from Tenant monthly estimated payments of the amounts Landlord reasonably estimates will be sufficient to pay Tenant's electricity and/or gas bills resulting from the Existing Gas Meter and the Existing Electric Meter pursuant to this paragraph (iv). ARTICLE VIII REAL ESTATE TAXES 8.1 PAYMENTS ON ACCOUNT OF REAL ESTATE TAXES. (a) For the purposes of this Article, the term "Tax Year" shall mean the twelve-month period commencing on the July 1 immediately preceding the Commencement Date and each twelve-month period thereafter commencing during the Term of this Lease; and the term "Taxes" shall mean all real estate taxes, special assessments and betterment assessments assessed with respect to the Property for any Tax Year. (b) Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) Taxes for each Tax Year (or partial Tax Year) falling within the Term of this Lease, multiplied by (ii) the Escalation Factor, such amount to be apportioned for any fraction of a Tax Year in which the Commencement Date falls or the Term of this Lease ends. (c) Estimated payments by Tenant on account of Taxes shall be made monthly and at the time and in the fashion herein provided for the payment of Basic Rent. The monthly amount so to be paid to Landlord shall be sufficient to provide Landlord by the time real estate tax payments are due a sum equal to Tenant's required payments, as estimated by Landlord from time to time, on account of Taxes for the then current Tax Year. Promptly after receipt by Landlord of bills for such Taxes, Landlord shall advise Tenant of the amount thereof and the computation of Tenant's payment on account thereof. If estimated payments theretofore made by Tenant for the Tax Year covered by such bills exceed the required payments on account thereof for such Year, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant on account of Taxes (or refund such overpayment if the Term of this Lease has ended and Tenant has no further obligation to Landlord); but if the -17- 22 required payments on account thereof for such Year are greater than estimated payments theretofore made on account thereof for such Year, Tenant shall make payment to Landlord within 30 days after being so advised by Landlord. Landlord shall have the same rights and remedies for the non-payment by Tenant of any payments due on account of Taxes as Landlord has hereunder for the failure of Tenant to pay Basic Rent. 8.2 ABATEMENT. If Landlord shall receive any tax refund or reimbursement of Taxes or sum in lieu thereof with respect to any Tax Year which is not due to vacancies in the Building, then out of any balance remaining thereof after deducting Landlord's expenses reasonably incurred in obtaining such refund, Landlord shall, provided there does not then exist a Default of Tenant, credit an amount equal to such refund or reimbursement or sum in lieu thereof (exclusive of any interest) multiplied by the Escalation Factor against the obligations of Tenant next falling due under this Article VIII; provided, that in no event shall Tenant be entitled to receive a credit equal to more than the payments made by Tenant on account of real estate tax increases for such Year pursuant to paragraph (b) of Section 8.1 or to receive any payments or abatement of Basic Rent if Taxes for any Year are less than Base Taxes or Base Taxes are abated. 8.3 ALTERNATE TAXES. (a) If some method or type of taxation shall replace the current method of assessment of real estate taxes in whole or in part, or the type thereof, or if additional types of taxes are imposed upon the Property or Landlord relating to the Property, Tenant agrees that Tenant shall pay a proportionate share of the same as an additional charge computed in a fashion consistent with the method of computation herein provided, to the end that Tenant's share thereof shall be, to the maximum extent practicable, comparable to that which Tenant would bear under the foregoing provisions. (b) If a tax (other than Federal or State net income tax) is assessed on account of the rents or other charges payable by Tenant to Landlord under this Lease, Tenant agrees to pay the same as an additional charge within ten (10) days after billing therefor, unless applicable law prohibits the payment of such tax by Tenant. ARTICLE IX OPERATING EXPENSES 9.1 DEFINITIONS. For the purposes of this Article, the following terms shall have the following respective meanings: - 18 - 23 (i) Operating Year: Each calendar year in which any part of the Term of this Lease shall fall. (ii) Operating Expenses: The aggregate costs or expenses reasonably incurred by Landlord with respect to the operation, administration, cleaning, repair, maintenance and management of the Property (but specifically excluding Utility Expenses) all as set forth in Exhibit E annexed hereto, provided that, if during any portion of the Operating Year for which Operating Expenses are being computed, less than all of Building Rentable Area was occupied by tenants or if Landlord is not supplying all tenants with the services being supplied hereunder, actual Operating Expenses incurred shall be reasonably extrapolated by Landlord on an item by item basis to the estimated Operating Expenses that would have been incurred if the Building were fully occupied for such Year and such services were being supplied to all tenants, and such extrapolated amount shall, for the purposes hereof, be deemed to be the Operating Expenses for such Year. (iii) Utility Expenses: The aggregate costs or expenses reasonably incurred by Landlord with respect to supplying electricity (other than electricity supplied to those portions of the Building leased to tenants), oil, steam, gas, water and sewer and other utilities supplied to the Property and not paid for directly by tenants, provided that, if during any portion of the Operating Year for which Utility Expenses are being computed, less than all Building Rentable Area was occupied by tenants or if Landlord is not supplying all tenants with the utilities being supplied hereunder, actual utility expenses incurred shall be reasonably extrapolated by Landlord on an item-by-item basis to the estimated Utility Expenses that would have been incurred if the Building were fully occupied for such Year and such utilities were being supplied to all tenants, and such extrapolated amount shall, for the purposes hereof, be deemed to be the Utility Expenses for such Year. 9.2 TENANT'S PAYMENTS. (a) Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) Operating Expenses for each Operating Year (or partial Operating Year) falling within in the Term of this Lease multiplied by (ii) the Escalation Factor, such amount to be apportioned for any partial Operating Year in which the Commencement Date falls or the Term of this Lease ends. (b) Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) Utility Expenses for each Operating Year (or partial Operating Year) falling within the Term of this Lease multiplied by (ii) the Escalation Factor, such amount to be apportioned for any partial -19- 24 Operating Year in which the Commencement Date falls or the Term of this Lease ends. (c) Estimated payments by Tenant on account of Operating Expenses shall be made monthly and at the time and in the fashion herein provided for the payment of Basic Rent. The monthly amount so to be paid to Landlord shall be sufficient to provide Landlord by the end of each Operating Year a sum equal to Tenant's required payments, as estimated by Landlord from time to time during each Operating Year, on account of Operating Expenses and Utility Expenses for such Operating Year. After the end of each Operating Year, Landlord shall submit to Tenant a reasonably detailed accounting of Operating Expenses and Utility Expenses for such Year, and Landlord shall certify to the accuracy thereof. If estimated payments theretofore made for such Year by Tenant exceed Tenant's required payment on account thereof for such Year, according to such statement, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant with respect to Operating Expenses and Utility Expenses (or refund such overpayment if the Term of this Lease has ended and Tenant has no further obligation to Landlord), but, if the required payments on account thereof for such Year are greater than the estimated payments (if any) theretofore made on account thereof for such Year, Tenant shall make payment to Landlord within thirty (30) days after being so advised by Landlord. Landlord shall have the same rights and remedies for the nonpayment by Tenant of any payments due on account of Operating Expenses and Utility Expenses as Landlord has hereunder for the failure of Tenant to pay Basic Rent. ARTICLE X INDEMNITY AND PUBLIC LIABILITY INSURANCE 10.1 TENANT'S INDEMNITY. To the maximum extent this agreement may be made effective according to law, Tenant agrees to defend, indemnify and save harmless Landlord from and against all claims, loss, liability, costs and damages of whatever nature arising from any default by Tenant under this Lease and the following: (i) from any accident, injury, death or damage whatsoever to any person, or to the property of any person, occurring in or about the Premises; (ii) from any accident, injury, death or damage occurring outside of the Premises but on the Property, where such accident, damage or injury results or is claimed to have resulted from an act or omission on the part of Tenant or Tenant's agents, employees, invitees or independent contractors; or (iii) in connection with the conduct or management of the Premises or of any business -20- 25 therein, or any thing or work whatsoever done, or any condition created (other than by Landlord) in or about the Premises; and, in any case, occurring after the date of this Lease, until the end of the Term of this Lease, and thereafter so long as Tenant is in occupancy of the Premises. This indemnity and hold harmless agreement shall include indemnity against all costs, expenses and liabilities incurred in, or in connection with, any such claim or proceeding brought thereon, and the defense thereof, including, without limitation, reasonable attorneys' fees and costs at both the trial and appellate levels. The provisions of this Section 10.1 shall survive the expiration or any earlier termination of this Lease. 10.2 PUBLIC LIABILITY INSURANCE. Tenant agrees to maintain in full force from the date upon which Tenant first enters the Premises for any reason, throughout the Term of this Lease, and thereafter so long as Tenant is in occupancy of any part of the Premises, a policy of general liability and property damage insurance (including broad form contractual liability, independent contractor's hazard and completed operations coverage) under which Landlord, Manager (and such other persons as are in privity of estate with Landlord as may be set out in notice from time to time) and Tenant are named as insureds, and under which the insurer agrees to defend, indemnify and hold Landlord, Manager, and those in privity of estate with Landlord, harmless from and against all cost, expense and/or liability arising out of or based upon any and all claims, accidents, injuries and damages set forth in Section 10.1. Each such policy shall be non-cancellable and non-amendable with respect to Landlord, Manager and Landlord's said designees without thirty (30) days' prior notice to Landlord and shall be in at least the amounts of the Initial Public Liability Insurance specified in Section 1.3 or such greater amounts as Landlord shall from time to time request, and a duplicate original or certificate thereof shall be delivered to Landlord. 10.3 TENANT'S RISK. To the maximum extent this agreement may be made effective according to law, Tenant agrees to use and occupy the Premises and to use such other portions of the Property as Tenant is herein given the right to use at Tenant's own risk; and Landlord shall have no responsibility or liability for any loss of or damage to Tenant's Removable Property or for any inconvenience, annoyance, interruption or injury to business arising from Landlord's making any repairs or changes which Landlord is permitted by this Lease or required by law to make in or to any portion of the Premises or other sections of the Property, or in or to the fixtures, equipment or appurtenances thereof. Tenant shall carry - 21 - 26 "all-risk" property insurance on a "replacement cost" basis (including so-called improvements and betterments), and provide a waiver of subrogation as required in Section 14.20. The provisions of this Section 10.3 shall be applicable from and after the execution of this Lease and until the end of the Term of this Lease, and during such further period as Tenant may use or be in occupancy of any part of the Premises or of the Building. 10.4 INJURY CAUSED BY THIRD PARTIES. To the maximum extent this agreement may be made effective according to law, Tenant agrees that Landlord shall not be responsible or liable to Tenant, or to those claiming by, through or under Tenant, for any loss or damage that may be occasioned by or through the acts or omissions of persons occupying adjoining premises or any part of the premises adjacent to or connecting with the Premises or any part of the Property or otherwise. The provisions of this Section 10.4 shall survive the expiration or any earlier termination of this Lease. ARTICLE XI LANDLORD'S ACCESS TO PREMISES 11.1 LANDLORD'S RIGHTS. Landlord shall have the right to enter the Premises at all reasonable hours for the purpose of inspecting or making repairs to the same, and Landlord shall also have the right to make access available at all reasonable hours to prospective or existing mortgagees, purchasers or tenants of any part of the Property. ARTICLE XII FIRE, EMINENT DOMAIN, ETC. 12.1 ABATEMENT OF RENT. If the Premises shall be damaged by fire or casualty, Basic Rent and Escalation Charges payable by Tenant shall abate proportionately for the period in which, by reason of such damage, there is substantial interference with Tenant's use of the Premises, having regard to the extent to which Tenant may be required to discontinue Tenant's use of all or a portion of the Premises, but such abatement or reduction shall end if and when Landlord shall have substantially restored the Premises (excluding any alterations, additions or improvements made by Tenant pursuant to Section 5.2) to the condition in which they were prior to such damage. If the Premises shall be affected by any -22- 27 exercise of the power of eminent domain, Basic Rent and Escalation Charges payable by Tenant shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant. In no event shall Landlord have any liability for damages to Tenant for inconvenience., annoyance, or interruption of business arising from such fire, casualty or eminent domain. 12.2 LANDLORD'S RIGHT OF TERMINATION. If the Premises or the Building are substantially damaged by fire or casualty (the term "substantially damaged" meaning damage of such a character that the same cannot, in ordinary course, reasonably be expected to be repaired within sixty (60) days from the time the repair work would commence), or if any part of the Building is taken by any exercise of the right of eminent domain, then Landlord shall have the right to terminate this Lease (even if Landlord's entire interest in the Premises may have been divested) by giving notice of Landlord's election so to do within 90 days after the occurrence of such casualty or the effective date of such taking, whereupon this Lease shall terminate thirty (30) days after 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. 12.3 RESTORATION, If this Lease shall not be terminated pursuant to Section 12.2, Landlord shall thereafter use due diligence to restore the Premises (excluding any alterations, additions or improvements made by Tenant) to proper condition for Tenant's use and occupation, provided that Landlord's obligation shall be limited to the amount of insurance proceeds available therefor. If, for any reason, such restoration shall not be substantially completed within six months after the expiration of the 90-day period referred to in Section 12.2 (which six-month period may be extended for such periods of time as Landlord is prevented from proceeding with or completing such restoration for any cause beyond Landlord's reasonable control, but in no event for more than an additional three months), Tenant shall have the right to terminate this Lease by giving notice to Landlord thereof within thirty (30) days after the expiration of such period (as so extended). Upon the giving of such notice, this Lease shall cease and come to an end without further liability or obligation on the part of either party unless, within such 30-day period, Landlord substantially completes such restoration. Such right of termination shall be Tenant's sole and exclusive remedy at law or in equity for Landlord's failure so to complete such restoration. 12.4 AWARD. Landlord shall have and hereby reserves and excepts, and Tenant hereby grants and assigns to -23- 28 Landlord, all rights to recover for damages to the Property and the leasehold interest hereby created, and to compensation accrued or hereafter to accrue by reason of such taking, damage or destruction, and by way of confirming the foregoing, Tenant hereby grants and assigns, and covenants with Landlord to grant and assign to Landlord, all rights to such damages or compensation. Nothing contained herein shall be construed to prevent Tenant from, at its sole cost and expense, prosecuting a separate condemnation proceeding with respect to a claim for the value of any of Tenant's Removable Property installed in the Premises by Tenant at Tenant's expense and for relocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by Landlord from the taking authority. ARTICLE XIII DEFAULT 13.1 TENANT'S DEFAULT. (a) If at any time subsequent to the date of this Lease any one or more of the following events (herein referred to as a "Default of Tenant") shall happen: (i) Tenant shall fail to pay the Basic Rent, Reimbursement Rent, Escalation Charges or other sums payable as additional charges hereunder when due; or (ii) Tenant shall neglect or fail to perform or observe any other covenant herein contained on Tenant's part to be performed or observed, or Tenant shall desert or abandon the Premises or the Premises shall become, or appear to have become vacant (regardless whether the keys shall have been surrendered or the rent and all other sums due shall have been paid), 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 (iii) Tenant's leasehold interest in the Premises shall be taken on execution or by other process of law directed against Tenant; or (iv) 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 -24- 29 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 (v) 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 (whether or not consecutive), 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 (whether or not consecutive); or (vi) If a Default of Tenant of the kind set forth in clauses (i) or (ii) above shall occur and if either (a) Tenant shall cure such Default within the applicable grace period or (b) Landlord shall, in its sole discretion , permit Tenant to cure such Default after the applicable grace period has expired, and an event which would constitute a similar Default if not cured within the applicable grace period shall occur more than once within the next 365 days, whether or not such event is cured within the applicable grace period; then in any such case (1) if such Default of Tenant shall occur prior to the Commencement Date, this Lease shall ipso facto, and without further act on the part of Landlord, terminate, and (2) if such Default of Tenant shall occur after the Commencement Date, Landlord may terminate this Lease by notice to Tenant, and thereupon this Lease shall come to an end as fully and completely as if such date were the date herein originally fixed for the expiration of the Term of this Lease, and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided. (b) If this Lease shall be terminated as provided in this Article, or if any execution or attachment shall be issued against Tenant or any of Tenant's property whereupon the Premises shall be taken or occupied by someone other than Tenant, then Landlord may, without notice, re-enter the Premises, either by force, summary -25- 30 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 of any termination, Tenant shall pay the Basic Rent, Escalation Charges and other sums payable hereunder up to the time of such termination, and thereafter Tenant, until the end of what would have been the Term of this Lease in the absence of such termination, and whether or not the Premises shall have been relet, shall be liable to Landlord for, and shall pay to Landlord, as liquidated current damages, the Basic Rent, Escalation Charges and other sums which would be payable hereunder if such termination had not occurred, less the net proceeds, if any, of any reletting of the Premises, after deducting all expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, legal expenses, attorneys' fees, advertising, expenses of employees, alteration costs and expenses of preparation for such reletting. Tenant shall pay such current damages to Landlord monthly on the days which the Basic Rent would have been payable hereunder if this Lease had not been terminated. (d) At any time after such termination, whether or not Landlord shall have collected any such current damages, as liquidated final damages and in lieu of all such current damages beyond the date of such demand, at Landlord's election Tenant shall pay to Landlord and amount equal to the excess, if any, of the Basic Rent, Escalation Charges and other sums as hereinbefore provided which would be payable hereunder from the date of such demand (assuming that, for the purposes of this paragraph, annual payments by Tenant on account of Taxes, Utility Expenses and Operating Expenses would be the same as the payments required for the immediately preceding Operating or Tax Year) for what would be the then unexpired Term of this Lease if the same had remained in effect, over the then fair net rental value of the Premises for the same period. (e) In the case of any Default by Tenant, re-entry, expiration and dispossession by summary proceeding 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 and -26- 31 necessary to re-let the same and (ii) may make such reasonable alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable and 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 such 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) If a Guarantor of this Lease is named in Section 1.2, the happening of any of the events described in paragraphs (a)(iv) or (a)(v) of this Section 13.1 with respect to the Guarantor shall constitute a Default of Tenant hereunder. (g) 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 to 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. (h) All costs and expenses incurred by or on behalf of Landlord (including, without limitation, attorneys' fees and expenses) in enforcing its rights hereunder or occasioned by any Default of Tenant shall be paid by Tenant. 13.2 LANDLORD'S DEFAULT. Landlord shall in no event be in default of the performance of any of Landlord's obligations hereunder unless and until Landlord shall have unreasonably failed to perform such obligation within a period of time reasonably required to correct any such default, after notice by Tenant to Landlord specifying wherein Landlord has failed TO perform any such obligations. ARTICLE XIV MISCELLANEOUS PROVISIONS 14.1 EXTRA HAZARDOUS USE. Tenant covenants and agrees that Tenant will not do or permit anything to be done in or -27- 32 upon the Premises, or bring in anything or keep anything therein, which shall increase the rate of property or liability insurance on the Premises or of the Building above the standard rate applicable to premises being occupied for Permitted Uses; and Tenant further agrees that, in the event that Tenant shall do any of the foregoing, Tenant will promptly pay to Landlord, on demand, any such increase resulting therefrom, which shall be due and payable as an additional charge hereunder. 14.2 WAIVER. (a) 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 the other's 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 any subsequent similar act by the other. (b) No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account of the earliest installment of any payment due from Tenant under the provisions hereof. The acceptance by Landlord 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 may, accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant. 14.3 COVENANT OF QUIET ENJOYMENT. Tenant, subject to the terms and provisions of this Lease, on payment of the Basic Rent and Escalation Charges and observing, keeping and performing all of the other 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 hereof, without hindrance or ejection by any persons lawfully claiming under Landlord to have title to the Premises superior to Tenant; the foregoing covenant of quiet enjoyment is in lieu of any other covenant, express or implied. 14.4 LANDLORD'S LIABILITY. (a) Tenant specifically agrees to look solely to Landlord's then equity interest in the -28- 33 Property at the time owned, for recovery of any judgment from Landlord; it being specifically agreed that Landlord (original or successor) shall never 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 to take any action not involving the personal liability of Landlord (original or successor) to respond in monetary damages from Landlord's assets other than Landlord's equity interest in the Property. (b) With respect to any services or utilities to be furnished by Landlord to Tenant, Landlord shall in no event be liable for failure to furnish the same when prevented from doing so by Force Majeure, strike, lockout, breakdown, accident, order or regulation of or by any governmental authority, or failure of supply, or inability by the exercise of reasonable diligence to obtain supplies, parts or employees necessary to furnish such services, or because of war or other emergency, or for any cause beyond Landlord's reasonable control, or for any cause due to any act or neglect of Tenant or Tenant's servants, agents, employees, licensees or any person claiming by, through or under Tenant; nor shall any such failure give rise to any claim in Tenant's favor that Tenant has been evicted, either constructively or actually, partially or wholly. (c) In no event shall Landlord ever be liable to Tenant for any loss of business or any other indirect or consequential damages suffered by Tenant from whatever cause. (d) With respect to any repairs or restoration which are required or permitted to be made by Landlord, the same may be made during normal business hours and Landlord shall have no liability for damages to Tenant for inconvenience, annoyance or interruption of business arising therefrom. 14.5 NOTICE TO MORTGAGEE OR GROUND LESSOR. After receiving notice from any person, firm or other entity that it holds a mortgage or a ground lease which includes the Premises, no notice from Tenant to Landlord alleging any default by Landlord shall be effective unless and until a copy of the same is given to such holder or ground lessor (provided Tenant shall have been furnished with the name and address of such holder or ground lessor), and the curing of any of Landlord's defaults by such holder or ground lessor shall be treated as performance by Landlord. -29- 34 14.6 ASSIGNMENT OF RENTS AND TRANSFER OF TITLE. (a) 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 on property which includes the Premises, Tenant agrees that the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage, shall never be treated as an assumption by such holder of any of the obligations of Landlord hereunder unless such holder shall, by notice sent to Tenant, specifically otherwise elect and that, except as aforesaid, such holder 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. (b) In no event shall the acquisition of Landlord's interest in the Property by a purchaser which, simultaneously therewith, leases Landlord's entire interest in the Property back to the seller thereof be treated as an assumption 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. In any such event, this Lease shall be subject and subordinate to the lease 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. (c) Except as provided in paragraph (b) of this Section, in the event of any transfer of title to the Property by Landlord, Landlord shall thereafter be entirely freed and relieved from the performance and observance of all covenants and obligations hereunder. 14.7 RULES AND REGULATIONS. Tenant shall abide by rules and regulations set forth in Exhibit C attached hereto and those rules and regulations from time to time established by Landlord, it being agreed that such rules and regulations will established and applied by Landlord in a non- discriminatory fashion, such that all rules and regulations shall be generally applicable to other tenants of the Building of similar nature to the Tenant named herein.

Any holding over by Tenant after the expiration of the Term of this Lease shall be treated as a daily tenancy at sufferance at a rate equal to the then fair rental value of the Premises but in no event less twice the sum of (i) Fixed Rent and (ii) Escalation Charges in effect on the expiration date. Tenant shall also pay to Landlord all damages, direct and/or indirect (including any loss of a tenant or rental income), sustained by reason of any such holding over. Otherwise, such holding over shall be on the terms and conditions set forth in this Lease as far as applicable.

Tenant shall remove all of Tenant's Removable Property and, to the extent specified by Landlord, all alterations and additions made by Tenant and all partitions wholly within the Premises; and shall repair any damage to the Premises or the Building caused by such removal. Any Tenant's Removable Property which shall remain in the Building or on the Premises after the expiration or termination of the Term of this Lease shall be deemed conclusively to have been abandoned, and either may be retained by Landlord as its property or may be disposed of in such manner as Landlord may see fit, at Tenant's sole cost and expense. 14.22 SUBSTITUTE SPACE. If Landlord so requests, Tenant shall vacate the Premises and relinquish its rights with respect to the same provided that Landlord shall provide to Tenant substitute space in the Building, such space to be reasonably comparable in size, layout, finish and utility to the Premises, and further provided that Landlord shall, at its sole cost and expense, move Tenant and its Removable Property from the Premises to such new space in such manner as will minimize, to the greatest extent practicable, undue interference with the business or operation of Tenant. Any such substitute space shall, from and after such relocation, be treated as the Premises demised under this Lease, and shall be occupied by Tenant under the same terms, provisions and conditions as are set forth in this Lease. 14.23 BROKERAGE. Tenant warrants and represents that Tenant has dealt with no broker in connection with the consummation of this Lease and, in the event of any brokerage claims against Landlord predicated upon prior dealings with Tenant, Tenant agrees to defend the same and indemnify Landlord against any such claim (except any claim by the Broker). 14.24 SPECIAL TAXATION PROVISIONS. Landlord shall have the right at any time and from time to time, to unilaterally amend the provisions of this Lease if Landlord is advised by its Counsel that all or any portion of the monies paid -35- 40 by Tenant to Landlord hereunder are, or may be deemed to be, unrelated business income within the meaning of the United States Internal Revenue Code, or regulation issued thereunder, and Tenant agrees that it will execute all documents or instruments necessary to effect such amendment or amendments, provided that no such amendment shall result in Tenant having to pay in the aggregate more money on account of its occupancy of the demised premises under the provisions of this Lease as so amended and provided further, that no such amendment or amendments shall result in Tenant receiving under the provisions of this Lease less services than it is entitled to receive nor services of a lesser quality. Anything contained in the foregoing provisions of this Lease (including, without limitation, Article VI hereof) to the contrary notwithstanding, neither Tenant nor any other person having an interest in the possession, use, occupancy or utilization of the Premises, shall enter into any lease, sublease, license, concession or other agreement for use, occupancy, utilization of space in the Premises which provides for rental or other payment for such use, occupancy or utilization of space, in whole or in part, on the net income or profits derived by any person from the Premises leased, used, occupied or utilized (other than an amount based on a fixed percentage or percentage of receipts for sales) and any such recorded lease, sublease, license, concession or other agreement shall be absolutely void and ineffective as a conveyance of any right or interest in the possession, use, occupancy or utilization of any part of the Premises. 14.25 HAZARDOUS MATERIALS. Tenant shall not (either with or without negligence) cause or permit the escape, disposal, release or threat of release of any biologically or chemically active or other Hazardous Materials (as said term is hereafter defined) on, in, upon or under the Property or the Premises.

If any lender or governmental agency shall ever require testing to ascertain whether or not there has been any release of Hazardous Materials, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand as additional charges but only if such requirement applies to the Premises or may be the result of the acts or omissions of Tenant. In addition, Tenant shall execute affidavits, representations and the like, from time to time, at Landlord's request concerning Tenant's best knowledge and belief regarding the presence of Hazardous Materials on the Premises. In all events, Tenant shall indemnify and save Landlord harmless from any release on threat of release on the presence or existence of Hazardous Materials on the Premises occurring while Tenant is in possession, or elsewhere on the Property if caused by Tenant or persons acting under Tenant. The within covenants and indemnity shall survive the expiration or earlier termination of the Term of this Lease. Landlord expressly reserves the right to enter the Premises to perform regular inspections. 14.26 GOVERNING LAW.
