If Tenant takes possession of any part of the Premises for the regular conduct of Tenant's business prior to the applicable Scheduled Commencement Date with Landlord's prior written consent, all of the covenants and conditions of the Lease will bind both parties with respect to such portion of the Premises, and Tenant will pay Landlord for such portion of the Premises for the period of such occupancy according to Section 4 of the Lease at the rates applicable to the first Lease Year (excluding any periods of excused or free rent, if any), prorated for the time and portion of the Premises so occupied. No early occupancy under this Section 3.2 will change the Commencement Date or the Expiration Date. 3.3 Delayed Occupancy Delayed Occupancy shall be governed by Paragraph 2 of Exhibit B attached hereto. 3.4 Surrender. Upon the expiration or other termination of the Term, Tenant will immediately vacate and surrender possession of the Premises in good order, repair and conditions, broom clean, except for ordinary wear and tear. Upon the expiration or other termination of the Term, at Landlord's option, Tenant agrees to (a) remove those changes, additions and improvements installed for or during Tenant's occupancy, whether made by Landlord (pursuant to Sections 7.3(b), 8.2, 12.2, or 14.2) or by Tenant, that were not approved in the initial buildout of the Premises or which Landlord, at the time that Tenant submitted plans for same for Landlord's approval pursuant to Section 9.1 herein, requested Tenant to remove, and (b) remove all of Tenant's trade fixtures, office furniture, office equipment and other personal property, including without limitation the items set forth in Exhibit G. Tenant will pay Landlord on demand the cost of repairing any damage to the Premises or Building caused by the installation or removal of any such items. Except as described herein in this Section 3.4, any of Tenant's property remaining in the Premises will be conclusively deemed to have been abandoned by Tenant and may be appropriated, stored, sold, destroyed or otherwise disposed of by Landlord without notice or obligation to account to or compensate Tenant, and Tenant will pay Landlord on demand all reasonable costs incurred by Landlord relating to such abandoned property. 3.5 Holding Over. Tenant understands that it does not have the right to hold over at any time unless agreed to by Landlord, in its sole discretion, and Landlord may exercise any and all remedies at law or in equity to recover possession of the premises, as well as any damages incurred by Landlord, due to Tenant's failure to vacate the Premises and deliver possession to Landlord as required by this Lease. If Tenant holds over after the Expiration Date without Landlord's prior written consent, Tenant will be deemed a tenant at sufferance, at a daily Base and Additional Rent, payable in advance, equal to 110% for the first thirty (30) days and 150% thereafter of the Base and Additional Rent per day payable during the last year of the Term, and Tenant will be bound by all of the other terms, covenants and agreements of this Lease as the same may apply to a tenancy at sufferance. The provisions of this Section 3.5 shall not operate as a waiver by Landlord of any right of re-entry hereinbefore provided. 7 12 4. RENT. 4.1 Base Rent Commencing on the Commencement Date and then throughout the Term, Tenant agrees to pay Landlord Base Rent according to the following provisions. Base Rent during each Lease Year (or portion of a Lease Year) described in Section 1.3(k) will be payable in monthly installments in the amount specified for such Lease Year (or portion) in Section 1.1(h), in advance, on or before the first day of each and every month during the Term. However, if the Term commences on other than the first day of a month or ends on other than the last day of a month, Base Rent for such month will be appropriately prorated. 4.2 Additional Rent. Tenant agrees to pay Landlord, as Additional Rent, in the manner provided below for each Fiscal Year that contains any part of the Term, Tenant's Share of (i) the amount of Expenses for such Fiscal Year ("Additional Expenses"); and (ii) the amount of Taxes for such Fiscal Year ("Additional Taxes"). (a) Estimated Payments. Prior to or as soon as practicable after the beginning of each Fiscal Year, Landlord will notify Tenant of Landlord's estimate of Tenant's Share of Additional Expenses and Additional Taxes for the ensuing Fiscal Year. On or before the first day of each month during the ensuing Fiscal Year, Tenant will pay to Landlord, in advance, 1/12 of such estimated amounts, provided that until such notice is given with respect to the ensuing Fiscal Year, Tenant will continue to pay on the basis of the prior Fiscal Year's estimate until the month after the month in which such notice is given. In the month Tenant first pays based on Landlord's new estimate, Tenant will pay to Landlord one-twelfth ((1)/12th) of the difference between the new estimate and the prior year's estimate for each month which has elapsed since the beginning of the current Fiscal Year. If at any time or times it appears to Landlord that Tenant's Share of Additional Expenses or Tenant's Share of Additional Taxes for the then-current Fiscal Year will vary from Landlord's estimate by more than 5%, Landlord may, by notice to Tenant, revise its estimate for such year and subsequent payments by Tenant for such year will be based upon the revised estimate, all of which are subject to the limitations contained in Section 4.7. (b) Annual Settlement. As soon as practicable, but no later than 120 days after the close of each Fiscal Year, Landlord will deliver to Tenant its statement of Tenant's Share of Additional Expenses and Additional Taxes for such Fiscal Year. If on the basis of such statement Tenant owes an amount that is less than the estimated payments previously made by Tenant for such Fiscal Year, Landlord will either refund such excess amount to Tenant or credit such excess amount against the next payment(s), if any, due from Tenant to Landlord. If on the basis of such statement Tenant owes an amount that is more than the estimated payments previously made by Tenant for such Fiscal Year, Tenant will pay the deficiency to Landlord within 30 days after the delivery of such statement. If this Lease commences on a day other than the first day of a Fiscal Year or terminates on a day other than the last day of a Fiscal Year, Tenant's Share of Additional Expenses and Additional Taxes applicable to the Fiscal Year in which such commencement or termination occurs will be prorated on the basis of the number of days within such Fiscal Year that are within the Term. (c) Final Payment. Tenant's obligation to pay the Additional Rent and Landlord's obligation to refund or credit any overpayment of Additional Rent provided for in this Section 4.2 which is accrued but not paid for periods prior to the expiration or early termination of the Term will survive such expiration or early termination. Prior to or as soon as practicable after the expiration or early termination of the Term, but no later than 120 days after the end of the Fiscal Year in which such expiration or early termination occurs, Landlord may submit an invoice to Tenant stating Landlord's estimate of the amount by which Tenant's Share of Additional Expenses and Additional Taxes through the date of such expiration or early termination will exceed Tenant's estimated payments of Additional Rent for the Fiscal Year in which such expiration or termination has occurred or will occur. Tenant will pay the amount of any such excess to Landlord or Landlord shall pay to Tenant the amount of any Tenant's overpayment within 30 days after the date of Landlord's invoice. 8 13 4.3 Other Taxes. Tenant will reimburse Landlord upon demand for any and all taxes payable by Landlord (other than net income taxes and taxes included in Taxes) whether or not now customary or within the contemplation of Landlord and Tenant: (a) upon, measured by or reasonably attributable to the cost or value of Tenant's equipment, furniture, fixtures and other personal property located in the Premises: (b) upon or measured by Rent; (c) upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Premises; and (d) upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. If it is not lawful for Tenant to reimburse Landlord, the Base Rent payable to Landlord under this Lease will be revised to yield to Landlord the same net rental after the imposition of any such tax upon Landlord as would have been payable to Landlord prior to the imposition of any such tax. 4.4 Terms of Payment. All Base Rent, Additional Rent and other Rent will be paid to Landlord (Solano Associates d/b/a TrizecHahn 120 South Riverside Management L.P.) in lawful money of the United States of America, at Old Kent Bank Slot 30243 PO Box 66973 Chicago IL 60666-0973 or to such other person or at such other place as Landlord may from time to time designate in writing, without notice or demand and without right of deduction, abatement or setoff, except as otherwise expressly provided in this Lease. 4.5 Interest on Late Payments. All amounts payable under this Lease by Tenant to Landlord, if not paid within 5 days of when due, will bear interest from the due date until paid at the lesser of the highest interest rate permitted by law or the then-current Prime Rate. 4.6 Right to Accept Payments. No receipt by Landlord of an amount less than Tenant's full amount due will be deemed to be other than payment "on account", nor will any endorsement or statement on any check or any accompanying letter effect or evidence an accord and satisfaction. Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance or pursue any right of Landlord. No payments by Tenant to Landlord after the expiration or other termination of the Term, or after the giving of any notice (other than a demand for payment of money) by Landlord to Tenant, will reinstate, continue or extend the Term or make ineffective any notice given to Tenant prior to such payment. After notice or commencement of a suit, or after final judgment granting Landlord possession of the Premises, Landlord may receive and collect any sums of Rent due under this Lease, and such receipt will not void any notice or in any manner affect any pending suit or any judgment obtained. 4.7 Expense Cap. "Capped Expenses" shall mean all Expenses exclusive of Non-Capped Expenses as defined below. For the purpose of determining Additional Rent, during the initial Term of the Lease only, Capped Expenses for any calendar year shall not be increased over the amount of Capped Expenses during the calendar year in which the term of this Lease commences by more than five percent (5%) per year on a cumulative basis, compounded annually. For example, if Capped Expenses during the calendar year in which the term of this Lease commences were $100,000, the cap on Capped Expenses for the fifth full calendar year would be $121,550.63 ($100,000 times 1.05 times 1.05 times 1.05 times 1.05). Notwithstanding what is set forth herein, Landlord shall not increase Capped Expenses more than ten percent (10%) in any one year, however, Landlord may carry over any increase in Capped Expenses over ten percent for a particular year to apply toward Capped Expenses in future years until recovered. It is understood and agreed that there shall be no cap on Non-Capped Expenses, which are hereby defined to mean all Expenses that in Landlord's sole discretion and judgment may be subject to increases which are outside of Landlord's control, including but not limited to, all utility expenses, snow removal expenses, insurance premiums, costs governed by collective bargaining, costs incurred due to requirements of Law or insurance carriers, major repairs, or costs incurred due to casualty or condemnation to the extent same are not reimbursed by insurance required to be carried under this Lease or by condemnation award. At no time shall there be any cap on Taxes. 9 14 4.8 Tenant's Right to Audit. Landlord shall maintain complete and accurate books and records detailing all Expenses and Taxes for not less than the preceding one (1) year. Landlord may keep the books and records at the Building or at Landlord's regional office. Within ninety days of receipt of Landlord's annual statement for Tenant's Share of Additional Expenses and Additional Taxes as described in Section 4.2(b) above and upon thirty (30) days written notice Tenant and/or its representatives (which shall be members of one of the "Big Five" accounting firms and shall not be compensated on a contingency fee basis for this audit) shall have the right, at Tenant's expense, to examine (but not to copy), and audit during normal business hours, Landlord's books and records pertaining to the Expenses and Taxes for the preceding year to enable Tenant to verify the accuracy thereof. Landlord shall reasonably cooperate with Tenant in any such examination. Any information reviewed by Tenant and/or its representatives shall be kept confidential and may only be disclosed as set forth in Section 26.10. If it is determined that the Expenses and Taxes reported by Landlord are in excess of one hundred five (105%) percent of the actual amount of Expenses and Taxes, then if (i) Landlord fails to dispute such finding, or (ii) Landlord agrees with such finding, or (iii) following a dispute of Tenant's audit by Landlord the reconciled audits still evidence that Tenant was overcharged by more than 5% as set forth above, then Tenant's reasonable actual costs of said audit shall be payable by Landlord on demand. Any overpayment by Tenant shall be credited to Tenant and any undercharge shall be paid by Tenant as soon as reasonably possible. Failure by Tenant to contest or dispute the allocation of Additional Rent within ninety days of receipt of Landlord's annual statement for Tenant's Share of Additional Expenses and Additional Taxes as described in Section 4.2(b) above (a) is deemed a waiver of the applicable audit or dispute right and any right to contest the Additional Rent charges (undercharges or overcharges) for the applicable Lease year; (b) is deemed acceptance of the Additional Rent charges as submitted to and reviewed by Tenant; and (c) CONSTITUTES FULL RELEASE OF LANDLORD BY TENANT FOR ANY OVERCHARGES of Additional Rent for the applicable Lease year . Such audit review by Tenant shall not postpone or alter the liability and obligation of Tenant to pay any amounts due under the Terms of the Lease, nor shall Tenant be entitled to conduct such an audit if Tenant is otherwise in Default under this Lease. No subtenant shall have any right to conduct an audit and no assignee shall conduct an audit for any period during which such assignee was not in possession of the Premises. The foregoing provisions shall survive termination or expiration of the Lease. 5. CONDITION OF PREMISES. Subject to any provision of this Lease concerning the making of Leasehold Improvements by Landlord in the Premises, including without limitation Exhibit B herein, by taking possession of the Premises hereunder, Tenant accepts the Premises as being in good order, condition and repair, and otherwise as is, where is and with all faults.

Tenant agrees that in the event it provides any plans or specifications for improvements, alterations or additions to the Premises pursuant to the terms and conditions of this Lease, Tenant shall be obligated to cause such plans to conform to all then applicable requirements of the ADA and shall otherwise cause them to be in accordance with the agreements contained in this Section 6.2(c) and Tenant shall notify Landlord of any particular requirements that Tenant may have to enable Landlord to meet its obligations under this Section 6.2(c).

Tenant agrees that its failure to comply with this Section 6.2(d) will constitute a material breach of the Lease; however, such agreement will not be deemed to limit the materiality of any other Tenant breach of the Lease for failure to comply with any other Rules and Regulations. 6.3 Occupancy. Tenant will not do or permit anything which obstructs or interferes with other tenants' rights or with Landlord's providing Building services, or which injures or annoys other tenants. Tenant will not cause, maintain or permit any nuisance in or about the Premises and will keep the Premises free of debris, and anything of a dangerous, noxious, toxic or offensive nature or which could create a fire hazard or undue vibration, heat or noise. If any item of equipment, building material or other property brought into the Building by Tenant or on Tenant's request causes a dangerous, noxious, toxic or offensive effect including an environmental effect) and in Landlord's reasonable opinion such effect will not be permanent but will only be temporary and is able to be eliminated, then Tenant will not be required to remove such item, provided that Tenant promptly and diligently causes such effect to be eliminated, pays for all costs of elimination and indemnifies Landlord against all liabilities arising from such effect. Tenant will not make or permit any use of the Premises which may jeopardize any insurance coverage, increase the cost of insurance or require additional insurance coverage. If by reason of Tenant's failure to comply with the provisions of this Section 6.3(a) any insurance coverage is jeopardized as evidenced by a written notice from Landlord's insurance carrier then Landlord will have the option to terminate this Lease after giving written notice to Tenant and providing that Tenant shall cure same as soon as reasonably possible after said notice but no less than 30 days thereafter and Tenant shall have failed to cure same within said cure period, or (b) insurance premiums are increased, then Landlord may require Tenant to immediately pay Landlord as Rent the amount of the increase in insurance premiums directly attributed to its use. Notwithstanding anything herein contained to the contrary, Landlord agrees that Tenant's Use of the Premises is an acceptable use under this Section 6.3 and this Lease and that occupancy of up to 1 person per 100 rentable square feet in the Premises is an acceptable level of occupancy for the Premises, except as otherwise specifically set forth in the Lease including Sections 7.1(b) and (f ) and shall not constitute a default hereunder. Notwithstanding what is set forth in the preceding sentence, Landlord makes no warranty or representation regarding the compliance of Tenant's Use or its occupancy of 1 person per 100 rentable square feet in the Premises with any zoning laws. 7.

A computer room will be constructed in the Premises at Tenant's cost and supplemental cooling provided therefore. If Tenant requires heating or air-conditioning for the Premises outside Business Hours, Landlord will furnish the same for the hours specified in a request from Tenant (which request will be made at the time and in the manner reasonably designated by Landlord for such requests from time to time), and for this service Tenant will pay Landlord, within 30 days after the date of Landlord's invoice, the hourly rate reasonably determined by Landlord from time to time; After hours charges for heating and cooling using interior VAV fan operation only shall be $45.00 per hour per floor; and (c) cold water from City of Chicago mains for small kitchens, hot and cold water for Building standard washrooms and water for drinking fountains (excluding water for air conditioning units for exclusive use by Tenant) Water for Tenant's supplemental air-conditioning systems, if any, is available at the rate reasonably determined by Landlord from time to time which as of the Date is $253.00 per ton per year.; and (d) janitorial services to the Premises and Building Common Areas, exclusive of Holidays.

Tenant's electrical use in the Premises shall not exceed the capacity of the existing system serving the Premises, nor shall Tenant use more than its proportionate share of the Building electrical riser capacity. Tenant may purchase from Landlord, Landlord's agent, or from a third party all lamps, bulbs, ballasts and starters used in the Premises (provided that Tenant may at its sole cost and expense engage directly a licensed union electrician to change lamps and bulbs used in the Premises). (b) Alternate Service Provider. Notwithstanding the foregoing, if permitted by Law, Landlord or Tenant shall have the right at any time and from time to time during the Term to either contract for service from a different company or companies providing electricity service (each such company shall hereinafter be referred to as an "Alternate Service Provider") or continue to contract for service from the Electric Service Provider. Tenant shall cooperate with Landlord, the Electric Service Provider, and any Alternate Service Provider at all times and, as reasonably necessary, shall allow Landlord, Electric Service Provider, and any Alternate Service Provider reasonable access to the Building's electric lines, feeders, risers, wiring, and any other machinery within the Premises. If Tenant selects an Alternate Service Provider to provide electricity service for the Building, Tenant shall make all necessary arrangements with the Alternate Service Provider for metering and paying for electric current furnished by the Alternate Service Provider to the Tenant and Tenant shall pay for all charges for electric current consumed on the Premises during the Term of this Lease.

Notwithstanding what is set forth herein, Tenant may not select an Alternate Service Provider that is different from the one selected for the Building by Landlord if Tenant's selection will adversely affect Landlord's selection of an Alternate Service Provider in any way. 7.3 Additional Services. (a) If Tenant requires electric current, water or any other utilities in excess of the amounts provided by Landlord according to Sections 7.1 and 7.2, such excess electric, water or other utility requirements will be supplied only with Landlord's consent, which consent will not be unreasonably withheld. If Landlord grants such consent, Tenant will pay all costs of meter service and installation of facilities or professional services necessary to measure and/or furnish 14 19 the required excess capacity. Tenant will also pay the entire cost at the prevailing rate of such additional electricity, water or other utility so required. (b) If Tenant installs any machines, equipment or devices in the Premises other than those approved by Landlord in the initial buildout of the Premises that do not constitute Customary Office Equipment and such machines, equipment or devices cause the temperature in any part of the Premises to exceed the temperature the Building's mechanical system would be able to maintain in the Premises were it not for such machines, equipment or devices, then Landlord reserves the right upon prior reasonable written notice and Tenant's failure to install same in a reasonable amount of time, to install supplementary air conditioning units in the Premises, and Tenant will pay Landlord all costs of installing, operating and maintaining such supplementary units. (c) If Tenant requires any janitorial or cleaning services in excess of the amounts provided by Landlord according to Section 7.1 (such as cleaning services beyond normal office janitorial services for areas such as kitchens, computer rooms or other special use areas), Landlord will provide such excess services to Tenant within a reasonable period after Tenant's request made to Landlord's Building manager ("Property Manager"), provided that such excess services are available from Landlord's regular janitorial or cleaning contractor. Tenant will pay the cost of such excess services at prevailing rates. Landlord will also provide, within a reasonable period after Tenant's request made to the Property Manager, at Tenant's cost and to the extent available to Landlord, replacement of bulbs, tubes or ballasts in any non-Building standard lighting fixtures in the Premises. (d) Tenant will pay as Rent, within 30 days after the date of Landlord's invoice, all costs which may become payable by Tenant to Landlord under this Section 7.3. 7.4 Interruption of Services. If any of the services provided for in this Section 7 are interrupted or stopped, Landlord will use due diligence to resume the service; provided, however, no irregularity or stoppage of any of these services will create any liability for Landlord (including, without limitation, any liability for damages to Tenant's personal property caused by any such irregularity or stoppage), constitute an actual or constructive eviction or, except as expressly provided below, cause any abatement of the Rent payable under this Lease or in any manner or for any purpose relieve Tenant from any of its obligations under this Lease. If, due to reasons within Landlord's reasonable control to remedy (provided such unavailability is not caused by Tenant, Tenant's Contractors or any of their respective agents or employees), any of the services required to be provided by Landlord under this Section 7 should become unavailable and should remain unavailable for a period in excess of three (3) days after notice of such unavailability from Tenant to Landlord, and if such unavailability should render all or any portion of the Premises where Tenant is actually unable to use any or all of the Premises for the normal conduct of its business ("Untenantable"), then commencing upon the expiration of such 3 day period, Tenant's Rent will equitably abate in proportion to the portion of the Premises so rendered Untenantable for so long as such services remain unavailable for such reasons. Without limiting those reasons for an irregularity or stoppage of services that may be beyond Landlord's control, any such irregularity or stoppage that is required in order to comply with any Laws will be deemed caused by a reason beyond Landlord's control. 8. REPAIRS. 8.1 Repairs Within the Premises. Subject to the terms of Sections 6, 7.1(a), 12 and 14, and except to the extent Landlord is required or elects to perform or pay for certain maintenance or repairs according to those sections, Tenant will, at Tenant's own expense: (a) at all times during the Term, maintain the Premises, including without limitation all glass, doors, fixtures, equipment, and appurtenances therein and those portions of any Exclusive Systems in good order and repair and in a condition that complies with all applicable Laws; and (b) promptly and adequately repair all damage to the Premises and replace or repair all of such glass, doors, fixtures, equipment and portions of the Exclusive Systems that are damaged or broken, all under the supervision of Landlord at Landlord's option and subject to the prior reasonable approval of 15 20 Landlord.

If Tenant fails to perform any of its obligations under Section 8.1, then Landlord may perform such obligations and Tenant will pay as Rent to Landlord the cost of such performance, including an amount sufficient to reimburse Landlord for overhead and supervision, within 30 days after the date of Landlord's invoice. For purpose of performing such obligations, or to inspect the Premises, Landlord may enter the Premises upon not less than 30 days' prior notice to Tenant provided that Tenant has not cured same within said period (except in cases of actual or suspected emergency, in which case no prior notice will be required or in cases where Tenant's failure to repair has an adverse affect on the Building or other tenants, in which case only 10 days notice will be required) without liability to Tenant for any loss or damage incurred as a result of such entry, provided that Landlord will take reasonable steps in connection with such entry to minimize any disruption to Tenant's business or its use of the Premises. 8.3 Notice of Damage. Tenant will notify Landlord promptly after Tenant learns of (a) any fire or other casualty in the Premises; (b) any damage to or defect in the Premises, including the fixtures and equipment in the Premises, for the repair of which Landlord might be responsible; and (c) any damage to or defect in any parts of appurtenances of the Building's sanitary, electrical heating, air conditioning, elevator or other systems located in or passing through the Premises. 9. ALTERATIONS. 9.1 Alterations by Tenant. Tenant may from time to time at its own expense make changes, additions and improvements to the Premises (individually or collectively referred to as "Alterations") to better adapt the same to its business, provided that any such Alterations: (a) will comply with all applicable Laws and Tenant will provide Landlord with permits evidencing same; (b) will be made only with the prior written consent of Landlord, which consent will not be unreasonably withheld; (c) will equal or exceed Building standard (d) will be carried out only by persons selected by Tenant and approved in writing by Landlord, who will if required by Landlord deliver to Landlord before commencement of the work performance and payment bonds; (e) do not exceed or adversely affect the capacity, maintenance, operating cost or integrity of the Building's structure or any of its heating, ventilating, air conditioning, plumbing, mechanical, electrical, communications or other systems; (f) is approved by the holder of any Encumbrance if so required by the terms of said Encumbrance; (g) does not violate any agreement which affects the Building or binds Landlord of which Tenant is given notice; (h) does not alter the exterior of the Building in any way. Tenant will maintain, or will cause the persons performing any such work to maintain, worker's compensation insurance and public liability and property damage insurance (with Landlord named as an additional insured), in amounts, with companies and in a form reasonably satisfactory to Landlord, which insurance will remain in effect during the entire period in which the work will be carried out. If requested by Landlord, Tenant will deliver to Landlord proof of all such insurance. Tenant will promptly pay, when due, the cost of all such work and, upon completion, Tenant will deliver to Landlord, to the extent not previously received by Landlord, evidence of payment, contractors' affidavits and full and final waivers of all liens for labor, services or materials. Tenant shall pay the Construction Administration Fee on all Alterations. Tenant will also pay any increase in property taxes on, or fire or casualty insurance premiums for, the Building attributable to such Alterations and the cost of any modifications to the Building outside the Premises that are required to be made in order to make the Alterations to the Premises. Tenant, at its expense, will have promptly prepared and submitted to Landlord reproducible as-built CAD plans of any such Alterations upon their completion. All permanent Alterations to the Premises, made or paid for by Landlord or Tenant will, without compensation to Tenant, become Landlord's property upon installation, subject to Section 3.4 herein. Notwithstanding the foregoing, Tenant shall have the right to make non-structural interior alterations to the Premises upon notice to 16 21 Landlord, but without first obtaining Landlord's prior written consent provided that: (i) such interior alterations shall be completed in a good and workman-like manner in accordance with Landlord's design criteria for the Building and the plans and specifications for the Premises originally approved by Landlord; (ii) the cost of any such interior alterations shall not exceed in the aggregate $25,000.00 per floor per Lease Year (the substitution of equipment in the Premises by Tenant shall not be included in the computation of said $25,000.00 amount); (iii) such interior alterations do not affect Building Systems and (iv) Tenant shall indemnify, defend and hold Landlord harmless from and against all claims, causes of action, damages and liabilities sustained by Landlord as a result of any such work performed by Tenant, its employees, agents or contractors, unless caused by the act or omission of Landlord. 9.2 Alterations by Landlord. Landlord may from time to time make repairs, changes, additions and improvements to the Building, Common Areas and those Building systems necessary to provide the services described in Section 7, and for such purposes Landlord may enter the Premises upon not less than 30 days' prior notice to Tenant (except in cases of actual or suspected emergency, in which case no prior notice will be required) without liability to Tenant for any loss or damage incurred as a result of such entry, provided that in doing so Landlord will not disturb or interfere with Tenant's use of the Premises and operation of its business any more than is reasonably necessary in the circumstances and will repair any damage to the Premises caused by such entry. No permanent change, addition or improvement made by Landlord will materially impair access to the Premises, however Landlord may temporarily close doors, entryways, public space and corridors within the Building and to interrupt or temporarily suspend services and facilities without being deemed or held guilty of an eviction of Tenant or for damages to Tenant's property, business or person, and the rent reserved herein shall in no way abate while said repairs, alterations, improvements or additions are being made, and Tenant shall not be entitled to maintain any set-off or counterclaim for damages of any kind against Landlord for any reason thereto. Landlord may, at its option, make all such repairs, alterations, improvements or additions in and about the Building and the Premises during ordinary business hours, but if Tenant desires to have the same done at any other time, Tenant shall pay for all overtime and additional expenses resulting therefrom. 10. LIENS. Tenant agrees to pay before delinquency all costs for work, services or materials furnished to Tenant for the Premises, the nonpayment of which could result in any lien against the Land or Building. Tenant will keep title to the Land and Building free and clear of any such lien. Tenant will immediately notify Landlord of the filing of any such lien or any pending claims or proceedings relating to any such lien and will indemnify and hold Landlord harmless from and against all loss, damages and expenses (including reasonable attorneys' fees) suffered or incurred by Landlord as a result of such lien, claims and proceedings. In case any such lien attaches, Tenant agrees to cause it to be immediately released and removed of record (failing which Landlord may do so at Tenant's sole expense), unless Tenant has a good faith dispute as to such lien in which case Tenant may contest such lien by appropriate proceedings so long as Tenant deposits with a title company acceptable to Landlord a bond or other security in an amount reasonably acceptable to Landlord which may be used by Landlord to release such lien. Upon final determination of any permitted contest, Tenant will immediately pay any judgment rendered and cause the lien to be released. 11. INSURANCE. 11.1 Landlord's Insurance. During the Term, Landlord will provide and keep in force the following insurance: (a) commercial general liability insurance relating to Landlord's operation of the Building, for personal and bodily injury and death, and damage to others' property; and 17 22 (b) all risk or fire insurance (including standard extended coverage endorsement perils, leakage from fire protective devices and other water damage) relating to the Land and Building (but excluding Tenant's fixtures, furnishings, equipment, personal property, documents, files, inventory, stock-in-trade and work products and all leasehold improvements in the Premises); and (c) loss of rental income insurance or loss of insurable gross profits commonly insured against by prudent landlords; and (d) boiler and machinery insurance; and (e) such other insurance as Landlord reasonably elects to obtain or any Building mortgagee requires. (f) workers' compensation insurance with limits as statutorily defined in the State of Illinois. Insurance effected by Landlord under this Section 11.1 will be in amounts which Landlord from time to time reasonably determines sufficient or any Building mortgagee requires; in the case of insurance under Section 11.1(b) will be for replacement value and for the insurance in Section 11.1(a) will not be less than the Liability Insurance Amount, will be subject to such deductibles and exclusions as Landlord reasonably determines; will, in the case of insurance under Sections 11.1 (b), (c) and (d), permit the release of Tenant from certain liability under Section 13.1 (as long as such permission can be obtained without material additional cost and without rendering void the protection afforded by the policy); and will otherwise be on such terms and conditions as Landlord from time to time reasonably determines sufficient. Tenant acknowledges that Landlord's loss of rental income insurance policy provides that payments by the insurer may be limited to a period of one year following the date of any damage or destruction and that no insurance proceeds will be payable in the case of damage or destruction caused by an occurrence not included in the policies described in Sections 11.1(b), (c) and (d). Landlord shall provide Tenant with a copy of certificates evidencing the above insurance prior to the Commencement Date and upon written request by Tenant but no more than once each Lease Year. 11.2 Tenant's Insurance. During the term, Tenant will provide and keep in force the following insurance: (a) commercial general liability insurance relating to Tenant's business (carried on, in or from the Premises) and Tenant's use and occupancy, for personal and bodily injury and death, and damage to others' property, with limits of not less than the Liability Insurance Amount for any one accident or occurrence; and (b) all risk or fire insurance (including standard extended endorsement perils, leakage from fire protective devices and other water damage) relating to Tenant's fixtures, furnishings, equipment, documents, files, work products, inventory, stock-in-trade and all leasehold improvements in the Premises on a full replacement cost basis in amounts sufficient to prevent Tenant from becoming a co-insurer and subject only to such deductibles and exclusions as Landlord may reasonably approve and (c) if any boiler or machinery is operated in the Premises, boiler and machinery insurance; and (d) business interruption insurance with a minimum limit equal to Tenant's annual rental expense; (e) workers' compensation insurance with limits as statutorily defined in the State of Illinois; (f) employers liability insurance with limits not less than $1,000,000. Landlord, the holder of any Encumbrance and any other entity requested by Landlord will be named as an additional insureds in the policy described in Section 11.2(a), which will include cross liability and severability of interests clauses and will be on an "occurrence" (and not a "claims made") form. Landlord, the holder of any Encumbrance and any other entity requested by Landlord will be named as a loss payee, as its interest may appear, in the policies described in Sections 11.2(b) and (c), and such policies will permit the release of Landlord 18 23 and the holder of any Encumbrance from certain liability under Section 13.2. Tenant's insurance policies will provide thirty (30) day notice to Landlord prior to cancellation and will otherwise be upon such terms and conditions as Landlord from time to time reasonably requires. Tenant will file with Landlord, on or before the Commencement Date and at least 10 days before the expiration date of expiring policies, such copies of either current policies, an insurance binder (countersigned by the insurer), Evidence of Insurance (in form Accord 27) or a binding certificate, or other proofs, as may be reasonably required to establish Tenant's insurance coverage in effect from time to time and payment of premiums. If Tenant fails to insure or pay premiums, or to file satisfactory proof as required, Landlord may, upon a minimum of 24-hours' notice, effect such insurance and recover from Tenant on demand any premiums paid. 11.3 Self Insurance Notwithstanding anything set forth to the contrary in this Lease, Tenant may, upon written notice to Landlord, self-insure the insurance coverage required under Section 11.2(b) above. However, the decision to self-insure shall not relieve Tenant of any liability as outlined in Section 11.2(b) above. Tenant shall hold Landlord harmless for any losses sustained that would have been covered by insurance had Tenant not elected to self-insure. This right to self insure is personal to Tenant and is not available to any subtenant or assignee without Landlord's prior written consent in its sole but reasonable discretion. 12. DAMAGE OR DESTRUCTION. 12.1 Termination Options. If the Premises or the Building are damaged by fire or other casualty Landlord will, promptly after learning of such damage, notify Tenant in writing of the time necessary to repair or restore such damage, as estimated by Landlord's architect, engineer or contractor (and shall use diligent efforts to provide same within 90 days of the casualty if commercially, reasonably possible). If such estimate states that repair or restoration of all of such damage that was caused to the Premises or to any other portion of the Building necessary for Tenant's occupancy cannot be completed within 180 days from the date of such damage (or within 30 days from the date of such damage if such damage occurred within the last 12 months of the Term), then Tenant will have the option to terminate this Lease. If such estimate states that repair or restoration of all such damage that was caused to the Building cannot be completed within 180 days from the date of such damage, or if such damage occurred within the last 12 months of the Term and such estimate states that repair or restoration of all such damage that was caused to the Premises or to any other portion of the Building necessary for Tenant's occupancy cannot be completed within 30 days from the date of such damage, or if such damage is not insured against by the insurance policies required to be maintained by Landlord according to Section 11.1, then Landlord will have the option to terminate this Lease. Any option to terminate granted above must be exercised by written notice to the other party given within 30 days after Landlord delivers to Tenant the notice of estimated repair time. If either party exercises its option to terminate this Lease, the Term will expire and this Lease will terminate 10 days after notice of termination is delivered; provided, however, that Rent for the period commencing on the date of such damage until the date this Lease terminates will be reduced to the reasonable value of any use or occupation of the Premises by Tenant during such period and Landlord will be entitled to all proceeds of the insurance policy described in Section 11.2(b) applicable to any damaged leasehold improvements in the Premises. 12.2 Repair Obligations. If the Premises or the Building are damaged by fire or other casualty and neither party terminates this Lease according to Section 12.1, Landlord shall be required to restore the Building and Premises to their condition prior to such destruction or damage, with reasonable promptness, subject to delays for insurance adjustments and delays caused by matters beyond Landlord's control. Landlord will have no liability to Tenant and Tenant will not be entitled to terminate this Lease if such repairs and restoration are not in fact completed within the estimated time period, provided that Landlord promptly commences and diligently pursues such repairs and restoration to completion. Notwithstanding what is set forth herein, Tenant may terminate this Lease if Landlord fails to repair the Premises or any portion of the Building necessary for Tenant's occupancy within 270 days from the date of casualty, subject to delays for insurance adjustments and delays caused by matters beyond Landlord's reasonable control, then Tenant may 19 24 terminate the Lease by written notice to Landlord. which notice shall be delivered to Landlord no later than fifteen (15) days after the date that such repairs should have been completed pursuant to the terms of the previous sentence, and then, unless such repairs have been completed the Lease will terminate thirty (30) days after Landlord's receipt of such notice. In no event will Landlord be obligated to repair, restore or replace any of the property required to be insured by Tenant according to Section 11.2; Tenant agrees to repair, restore or replace such property as soon as possible after the date of damage, to at least the condition existing prior to its damage, using materials at least equal to Building standard. However, in connection with its repair and restoration of such damage, Landlord may, at its option, elect to repair and restore the damage, if any, caused to all of the leasehold improvements required to be insured by Tenant according to Section 11.2(b). If Landlord makes such election, Landlord will be entitled to all proceeds of the insurance policy described in Section 11.2(b) applicable to the leasehold improvements Landlord so elects to repair or restore. 12.3 Rent Abatement. If any fire or casualty damage renders the Premises untenantable and if this Lease is not terminated according to Section 12.1 or 12.2, then Rent will abate beginning on the date of such damage. Such abatement will end on the date which is the earlier of (i) the date the Tenant fully reopens for business in such portion of the Premises, and (ii) the date which is ninety (90) days after the Landlord has substantially completed the repairs and restoration Landlord is required to perform according to Section 12.2. Such abatement will be in an amount bearing the same ratio to the total amount of Rent for such period as the Untenantable portion of the Premises bears to the entire Premises. In no event will Landlord be liable for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting in any way from damage caused by fire or other casualty or the repair of such damage, provided however that, to the extent Tenant remains in possession of a portion of the Premises, Landlord will take all reasonable steps to minimize the disruption to Tenant's business and use of such portion of the Premises during the period of repair. 13. WAIVERS AND INDEMNITIES. 13.1 Landlord's Waivers. As used in this Section 13, a party's "Affiliates" means that party's parent, subsidiary and affiliated corporations and its and their partners, directors, officers, shareholders, agents, servants and employees. Tenant and its Affiliates will not be liable or in any way responsible to Landlord for, and Landlord waives all claims against Tenant and its Affiliates for, any loss, injury or damage that is insured or required to be insured by Landlord under Sections 11.1(b), (c) or (d), so long as such loss, injury or damage results from or in connection with this Lease or Tenant's use and occupancy of the Premises. Landlord's waivers under this Section 13.1 will survive the expiration or early termination of the Term. 13.2 Tenant's Waivers. Except to the extent caused by the willful or negligent act or omission or breach of this Lease by Landlord or anyone for whom Landlord is legally responsible, Landlord, its Affiliates and the holder of any Encumbrance will not be liable or in any way responsible for, and Tenant waives all claims against Landlord, its Affiliates and the holder of any Encumbrance for any loss, injury or damage suffered by Tenant or others relating to (a) loss or theft of, or damage to, property of Tenant or others; (b) injury or damage to persons or property resulting from fire, explosion, falling plaster, escaping steam or gas, electricity, water, rain or snow, or leaks from any part of the Building or from any pipes, appliances or plumbing, or from dampness; or (c) damage caused by other tenants, occupants or persons in the Premises or other premises in the Building, or caused by the public or by construction of any private or public work. Landlord, its Affiliates and the holder of any Encumbrance will not be liable or in any way responsible to Tenant for, and Tenant waives all claims against Landlord, its Affiliates and the holder of any Encumbrance for, any loss, injury or damage that is insured or required to be insured by Tenant under Sections 11.2(b) or (c), so long as such loss, injury or damage results from or in connection with this Lease or Landlord's operation of the Building. Tenant's waivers under this Section 13.2 will survive the expiration or early termination of the Term. 20 25 13.3 Landlord's Indemnity. Subject to Section 7.4 and 13.2 and except to the extent caused by the willful or negligent act or omission or breach of this Lease by Tenant or anyone for whom Tenant is legally responsible, Landlord will indemnify and hold Tenant harmless from and against any and all liability, loss, claims, demand, damages or expenses (including reasonable attorneys' fees) due to or arising out of any willful or negligent act or omission or breach of this Lease by Landlord or anyone for whom Landlord is legally responsible. Landlord's obligations under this Section 13.3 will survive the expiration or early termination of the Term. 13.4 Tenant's Indemnity. Subject to Section 13.1 and except to the extent caused by the willful or negligent act or omission or breach of this Lease by Landlord or anyone for whom Landlord is legally responsible, Tenant will indemnify and hold Landlord and the holder of any Encumbrance harmless from and against any and all liability, loss, claims, demands, damages or expenses (including reasonable attorneys' fees) due to or arising out of any accident or occurrence on or about the Premises (including, without limitation, accidents or occurrences resulting in injury, death, property damage or theft) or any willful or negligent act or omission of or breach of this Lease by Tenant or anyone for whom Tenant is legally responsible. Tenant's obligations under this Section 13.4 will survive the expiration or early termination of the Term. 14. CONDEMNATION. 14.1 Full Taking. If all or substantially all of the Building or Premises are taken for any public or quasi-public use under any applicable Laws or by right of eminent domain, or are sold to the condemning authority in lieu of condemnation, then this Lease will terminate as of the date the earlier of when the condemning authority takes physical possession of or title to the Building or Premises. 14.2 Partial Taking. (a) Landlord's Termination of Lease. If only part of the Building or Premises is thus taken or sold, and if after such partial taking, in Landlord's reasonable judgment, alteration or reconstruction is not economically justified, then Landlord (whether or not the Premises are affected) may terminate this Lease by giving written notice to Tenant within 60 days after the taking. (b) Tenant's Termination. If over 20% of the Premises is thus taken or sold and Landlord is unable to provide Tenant with comparable replacement premises in the Building, Tenant may terminate this Lease if in Tenant's reasonable judgment the Premises cannot be operated by Tenant in an economically viable fashion because of such partial taking. Such termination by Tenant must be exercised by written notice to Landlord given not later than 60 days after Tenant is notified of the taking of the Premises. (c) Effective Date of Termination. Termination by Landlord or Tenant will be effective as of the date when physical possession of the applicable portion of the Building or Premises is taken by condemning authority. (d) Election to Continue Lease. If neither Landlord nor Tenant elects to terminate this Lease upon a partial taking of a portion of the Premises, the Rent payable under this Lease will be diminished by an amount allocable to the portion of the Premises which was so taken or sold. If this Lease is not terminated upon a partial taking of the Building or Premises, Landlord will, at Landlord's sole expense, promptly restore and reconstruct the Building and Premises to substantially their former condition to the extent the same is feasible. However, Landlord will not be required to spend for such restoration or reconstruction an amount in excess of the net amount received by Landlord as compensation or damages for the part of the Building or Premises so taken. 21 26 14.3 Awards. As between the parties to this Lease, Landlord will be entitled to receive, and Tenant assigns to Landlord, all of the compensation awarded upon taking of any part or all of the Building or Premises, including any award for the value of the unexpired Term. However, Tenant may assert a claim in a separate proceeding against the condemning authority for any damages resulting from the taking of Tenant's trade fixtures or personal property, or for moving expenses, business relocation expenses or damages to Tenant's business incurred as a result of such condemnation. 15. ASSIGNMENT AND SUBLETTING. 15.1 Limitation. Without Landlord's prior written consent, Tenant will not assign all or any of its interest under this Lease, sublet all or any part of the Premises or permit the Premises to be used by any parties other than Tenant, its employees and its Permitted Transferees pursuant to Section 15.7 herein. 15.2 Notice of Proposed Transfer; Landlord's Options. If Tenant desires to enter into any assignment of this Lease or a sublease of all or any part of the Premises, Tenant will first give Landlord written notice of the proposed assignment or sublease, which notice will contain the name and address of the proposed transferee, the proposed use of the Premises, statements reflecting the proposed transferee's current financial condition and income and expenses for the past 2 years, a copy of the fully executed proposed assignment or sublease and any other information reasonably requested by Landlord. Except in the case of any transfer permitted under Section 15.7, Landlord will have the option, upon the receipt of such notice to cancel this Lease in the case of a proposed assignment of this Lease or a proposed subletting of all the Premises, or to cancel this Lease with respect to the portion to be so subleased, in which latter event the Base Rent and Tenant's Share as defined herein shall be adjusted on the basis of the number of square feet of rentable area of the Premises retained by Tenant, and this Lease as so amended shall continue thereafter in full force and effect. If Landlord wishes to exercise such option to cancel, Landlord shall, within ten (10) business days after Landlord's receipt of such notice from Tenant, send to Tenant a notice so stating and in such notice Landlord shall specify the date as of which such cancellation is effective, which date shall be not less than thirty (30) and not more than ninety (90) days after the date on which Landlord sends such notice. Tenant shall pay Landlord's reasonable costs and attorney's fees for review of the assignment or subletting documentation, of not less than $500.00 but not more than $1,000.00 per assignment or sublease. 15.3 Consent Not to Be Unreasonably Withheld. If Landlord does not exercise its applicable option under Section 15.2, then within said ten (10) business days of the receipt of the documentation set forth in Section 15.2 above, Landlord will either consent to or disapprove of the proposed assignment or sublease. Landlord will not unreasonably withhold or delay its consent to the proposed assignment or subletting if each of the following conditions is satisfied: (a) the proposed transferee, in Landlord's reasonable opinion, has sufficient financial capacity and business experience to perform Tenant's obligations under this Lease; and (b) the proposed transferee will make use of the Premises which in Landlord's reasonable opinion (i) is lawful, (ii) is consistent with the permitted use of the Premises under this Lease, (iii) is consistent with the general character of business carried on by tenants of a first-class office building, (iv) does not conflict with any exclusive rights or covenants not to compete in favor of any other tenant or proposed tenant of the Building, (v) will not increase the likelihood of damage or destruction to the Building, (vi) will not cause an increase in insurance premiums for insurance policies applicable to the Building, and (viii) will not require new tenant improvements incompatible with then-existing Building systems and components; and (c) the proposed transferee does not have a poor business reputation or reputation as being an undesirable tenant in the general business community. 22 27 (d) the proposed transferee, at the time of the proposed transfer, is neither a tenant in the Building or the 10 South Riverside Building for whom Landlord has space of an adequate size to fulfill such tenant's needs in either building, nor a party with whom Landlord is then negotiating for the lease of space in the Building or the 10 South Riverside Building; and (e) Intentionally deleted; and (f) at the time of the proposed transfer no "Default" (as defined in Section 20.1) exists under this Lease. 15.4 Form of Transfer. If Landlord consents to a proposed assignment of sublease, Landlord's consent will not be effective unless and until Tenant delivers to Landlord an original duly executed assignment or sublease, as the case may be, that provides, in the case of a sublease, that the subtenant will comply with all applicable terms and conditions of this Lease, and, in the case of an assignment, an assumption by the assignee of all of the terms, covenants and conditions which this Lease requires Tenant to perform. 15.5 Payments to Landlord. If Landlord does not exercise its applicable option under section 15.2 and Tenant effects an assignment or sublease, then Landlord will be entitled to receive and collect, either from Tenant or directly from the transferee, 50% of the amount by which the consideration required to be paid by the transferee for the use and enjoyment of Tenant's rights under this Lease. (after deducting from such consideration Tenant's reasonable costs incurred in effecting the assignment or sublease) exceeds the Rent payable by Tenant to Landlord allocable to the transferred space. Such percentage of such amount will be payable to Landlord at the time(s) Tenant receives the same from its transferee (whether in monthly installments, in a lump sum, or otherwise). 15.6 Change of Ownership. Any change by Tenant in the form of its legal organization (such as, for example, a change from a general to a limited partnership), any transfer of 51% or more of Tenant's assets, and any other transfer of interest effecting a change in identity of persons exercising effective control of Tenant will be deemed an "assignment" of this Lease requiring Landlord's prior written consent. The transfer of any outstanding capital stock of a corporation whose stock is publicly-traded will not, however, be deemed a "transfer of interest" under this Section 15.6. 15.7 Permitted Transfers. Tenant may, upon notice to Landlord, but without obtaining Landlord's consent, assign this Lease or sublease all or any part of the Premises to (i) any corporation which controls, is controlled by, or is under common control with Tenant, (ii) any corporation resulting from the merger or consolidation of Tenant, or (iii) any person or entity which acquires all of the assets of Tenant as a going concern of the business that is being conducted on the Premises, provided that such transferee assumes in full the obligations of Tenant under the Lease ("Permitted Transferee"). Notwithstanding the foregoing, Tenant's right to assign or sublet without Landlord's consent is conditioned upon (x) the transferee having a net worth, as reflected by audited financial statements, equal to or greater than that of Tenant as of the date of this Lease, and (y) the transferee not being engaged in a business that violates the provisions of any existing leases governing in the Building 15.8 Effect of Transfers. No subletting or assignment will release Tenant from any of its obligations under this Lease unless Landlord agrees to the contrary in writing. Acceptance of Rent by Landlord from any person other than Tenant will not be deemed a waiver by Landlord of any provision of this Section 15. Consent to one assignment or subletting will not be deemed a consent to any subsequent assignment or subletting. In the event of any default by any assignee or subtenant or any successor of Tenant in the performance of any Lease obligation, Landlord may proceed directly against Tenant without exhausting remedies against such assignee, subtenant or successor. The voluntary or other surrender of this Lease 23 28 by Tenant or the cancellation of this Lease by mutual agreement of Tenant and Landlord will not work a merger and will, at Landlord's option, terminate all or any subleases or operate as an assignment to Landlord of all or any subleases; such option will be exercised by notice to Tenant and all known subtenants in the Premises. If Landlord shall choose to take an assignment of a sublease then the subtenant shall be bound to Landlord for the balance of the Term thereof and shall attorn directly to Landlord under all of the executory terms of the sublease except that Landlord shall not (a) be liable for any previous act, omission or negligence of Tenant, (b) be subject to any counterclaim, defense or offset not expressly provided for in the sublease and accruing against Tenant, (c) be bound by any previous modification or amendment of the sublease made without Landlord's consent or by any previous prepayment of more than one month's Rent, or (d) be obligated to perform any repairs or other work beyond Landlord's obligation under this Lease. Each subtenant shall execute and deliver such instruments as Landlord may reasonably request to evidence said attornment. 16. PERSONAL PROPERTY. 16.1 Installation and Removal. Tenant may install in the Premises its personal property (including Tenant's usual trade fixtures) in a proper manner, provided that no such installation will interfere with or damage the mechanical, plumbing or electrical systems or the structure of the Building, and provided further that if such installation would require any change, addition or improvement to the Premises, such installation will be subject to Section 9.1. Any such personal property installed in the Premises by Tenant (a) may be removed from the Premises from time to time in the ordinary course of Tenant's business or in the course of making any changes, additions or improvements to the Premises permitted under Section 9.1, and (b) will be removed by Tenant at the end of the Term according to Section 3.4. Tenant will promptly repair at its expense any damage to the Building resulting from such installation or removal. 16.2 Responsibility. Tenant will be solely responsible for all costs and expenses related to personal property used or stored in the Premises. Tenant will pay any taxes or other governmental impositions levied upon or assessed against such personal property, or upon Tenant for the ownership or use of such personal property, on or before the due date for payment. Such personal property taxes or impositions are not included in Taxes. 16.3 Landlord's Lien. Intentionally Deleted. 17. ESTOPPEL CERTIFICATES. Promptly upon Landlord's request after Tenant has occupied the Premises, Tenant will execute and deliver to Landlord an Occupancy Estoppel Certificate in the form of Exhibit C. In addition, the parties agree that at any time and from time to time (but on not less than 10 days prior written request by either party and not more than once each Lease Year by Tenant), the other party will execute, acknowledge and deliver to the requesting party a certificate indicating any or all of the following: (a) the Commencement Date and Expiration Date; (b) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect or the reason it is not, as modified, and stating the date and nature of each modification); (c) the date, if any, through which Base Rent, Additional Rent and any other Rent payable have been paid; (d) that no default by the requesting party, to the best of the other party's knowledge, or the other party exists which has not been cured, except as to defaults stated in such certificate; (e) provided such events have occurred, that Tenant has accepted the Premises and that all improvements required to be made to the Premises by Landlord have been completed according to this Lease; (f) that, except as specifically stated in such certificate, Tenant, and only Tenant, currently occupies the Premises; (g) the amount of Security Deposit held by Landlord and (h) such other matters as may be reasonably requested by said party. Any such certificate may be relied upon by the requesting party and any 24 29 prospective purchaser or present or prospective mortgagee, deed of trust beneficiary or ground lessor of all or a portion of the Building. 18. TRANSFER OF LANDLORD'S INTEREST. 18.1 Sale, Conveyance and Assignment. Nothing in this Lease will restrict Landlord's right to sell, convey, assign or otherwise deal with the Building or Landlord's interest under this Lease. 18.2 Effect of Sale, Conveyance or Assignment. A sale, conveyance or assignment of the Building will automatically release Landlord from liability under this Lease from and after the effective date of the transfer, except for any liability relating to the period prior to such effective date; and Tenant will look solely to Landlord's transferee for performance of Landlord's obligations relating to the period after such effective date. This Lease will not be affected by any such sale, conveyance or assignment and Tenant will attorn to Landlord's transferee. 18.3 Subordination and Nondisturbance. This Lease is and will be subject and subordinate in all respects to any ground lease, mortgage or deed of trust now or later encumbering the Building, and to all their renewals, modifications, supplements, consolidations and replacements (an "Encumbrance"). With respect to any Encumbrance first encumbering the Building subsequent to the Date of this Lease, Landlord will , at Landlord's sole cost and expense to cause the holder of such Encumbrance to agree (either in the Encumbrance or in a separate agreement with Tenant, which agreement shall be in a form reasonably acceptable to Tenant, with the parties acknowledging that the form set forth in Exhibit E is acceptable to Tenant) that so long as Tenant is not in default of its obligations under this Lease, this Lease will not be terminated and Tenant's possession of the Premises will not be disturbed by the termination or foreclosure, or proceedings for enforcement, of such Encumbrance. While such subordination will occur automatically, Tenant agrees, upon request by and without cost to Landlord or any successor in interest, to promptly execute and deliver to Landlord or the holder of an Encumbrance such instrument(s) as may be reasonably required to evidence such subordination. In the alternative, however, the holder of an Encumbrance may unilaterally elect to subordinate such Encumbrance to this Lease. This Lease is subject to the Tenant at Landlord's sole cost and expense obtaining a Subordination and Non-Disturbance Agreement in the form set forth in Exhibit E, attached and incorporated, from the Equitable Life Assurance Company, the existing holder of the mortgage covering the Building. Landlord agrees to use reasonable efforts to obtain, such agreement. If such agreement is not obtained within thirty (30) days after the Date, either Landlord or Tenant may terminate this Lease by giving written notice of termination to the other party within thirty five (35) days after the Date. Unless such agreement has then been obtained, this Lease will terminate upon the giving of such notice. Such termination right will be in full settlement of all claims that either party might otherwise have against the other by reason of Landlord's failure to deliver said Agreement. 18.4 Attornment. If the interest of Landlord is transferred to any person (a "Successor Landlord") by reason of the termination or foreclosure, or proceedings for enforcement, of an Encumbrance, or by delivery of a deed in lieu of such foreclosure or proceedings, Tenant will immediately and automatically attorn to the Successor Landlord. Upon attornment this Lease will continue in full force and effect as a direct lease between the Successor Landlord and Tenant, upon all of the same terms, conditions and covenants as stated in this Lease Lease except that a Successor Landlord shall not be (a) liable for any previous act or omission or negligence of Landlord under this Lease, (b) subject to any counterclaim defense or offset not expressly provided for in this Lease and asserted with reasonable promptness, which therefore shall have accrued to Tenant against Landlord, (c) bound by any previous modification or amendment of this Lease or by any previous prepayment of more than one month's rent, unless such modification or prepayment shall have been approved in writing by the holder of any Encumbrance through or by reason of which the Successor Landlord shall have succeeded to the rights of Landlord under this Lease or (d) obligated to perform any repairs or other work beyond Landlord's obligations under this Lease.. Tenant agrees, upon request by and without cost to 25 30 the Successor Landlord, to promptly execute and deliver to the Successor Landlord such instrument(s) as may be reasonably required to evidence such attornment. 19. rules and regulations. Tenant agrees to faithfully observe and comply with the Rules and Regulations set forth in Exhibit D and with all reasonable modifications and additions to such Rules and Regulations (which will be applicable to all Building tenants) from time to time adopted by Landlord and of which Tenant is notified in writing. No such modification or addition will contradict or abrogate any right expressly granted to Tenant under this Lease. Landlord's enforcement of the Rules and Regulations will be uniform and nondiscriminatory, but Landlord will not be responsible to Tenant for failure of any person to comply with the Rules and Regulations. Violation of any rule or regulation shall constitute a default under Section 20.1(b) herein and shall be subject to the notice and cure provisions thereunder. 20. TENANT'S DEFAULT AND LANDLORD'S REMEDIES. 20.1 Default. This Lease and the Term and estate hereby granted are subject to the following limitations which will each constitute a material breach by Tenant and a "Default" under this Lease: (a) Failure to Pay Rent. Tenant fails to pay Base Rent, Additional Rent or any other Rent payable by Tenant under the terms of this Lease when due, and such failure continues for 5 days after written notice from Landlord to Tenant of such failure; provided that with respect to Base Rent and Additional Rent, Tenant will be entitled to only 3 notices of such failure during any Lease Year and if, after 3 such notices are given in any Lease Year, Tenant fails, during such Lease Year, to pay any such amounts when due, such failure will constitute a Default without further notice by Landlord or additional cure period. (b) Failure to Perform Other Obligations. Tenant breaches or fails to comply with any other provision of this Lease applicable to Tenant, and such breach or noncompliance continues for a period of 30 days after notice by Landlord to Tenant; or, if such breach or noncompliance cannot be reasonably cured within such 30-day period, Tenant does not in good faith commence to cure such breach or noncompliance within such 30-day period or does not diligently complete such cure as soon as possible, but no later than 60 days after such notice from Landlord. However, if such breach or noncompliance causes or results in (i) a dangerous condition on the Premises or the Building, (ii) any insurance coverage carried by Landlord or Tenant with respect to the Premises or Building being jeopardized, or (iii) a material disturbance to another tenant, then a Default will exist if such breach or noncompliance is not cured as soon as reasonably possible after notice by Landlord to Tenant, and in any event is not cured within 30 days after such notice. For purposes of this Section 20.1 (b), financial inability will not be deemed a reasonable ground for failure to immediately cure any breach of, or failure to comply with, the provisions of this Lease. (c) Intentionally Deleted. (d) Transfer of Interest without Consent. Tenant's interest under this Lease or in the Premises is transferred or passes to, or devolves upon, any other party in violation of Section 15. (e) Execution and Attachment Against Tenant. Tenant's interest under this Lease or in the Premises is taken upon execution or by other process of law directed against Tenant, or is subject to any attachment by any creditor or claimant against Tenant and such attachment is not discharged or disposed of within 15 days after levy. (f) Bankruptcy or Related Proceedings. Tenant files a petition in bankruptcy or insolvency, or reorganization or arrangement under any bankruptcy or insolvency Laws, or voluntarily takes advantage of any such Laws by answer or otherwise, or dissolves or makes an assignment for the benefit of creditors, or involuntary proceedings under any such 26 31 Laws or for the dissolution of Tenant are instituted against Tenant, or a receiver or trustee is appointed for the Premises or for all or substantially all of Tenant's property, and such proceedings are not dismissed or such receivership or trusteeship vacated within 90 days after such institution or appointment. 20.2 Remedies. Time is of the essence. If any Default occurs, Landlord will have the right, at Landlord's election, then or at any later time, to exercise any one or more of the remedies described below. Exercise of any of such remedies will not prevent the concurrent or subsequent exercise of any other remedy provided for in this Lease or otherwise available to Landlord at law or in equity. Notwithstanding, Landlord shall be obligated at all times to use it's reasonable efforts to mitigate Landlord's damages caused by Tenant's Default. (a) Cure by Landlord. Landlord may, at Landlord's option, after providing tenant notice and the opportunity to cure as set forth in Section 20.1 above, but without obligation to do so, and without releasing Tenant from any obligations under this Lease, make any payment or take any action as Landlord deems necessary or desirable to cure any Default in such manner and to such extent as Landlord deems necessary or desirable. Landlord may do so without additional demand on, or additional written notice to, Tenant and without giving Tenant an additional opportunity to cure such Default. Tenant covenants and agrees to pay Landlord, upon demand, all advances, costs and expenses of Landlord in connection with making any such payment or taking any such action, including reasonable attorney's fees, together with interest at the rate described in Section 4.5, from the date of payment of any such advances, costs and expenses by Landlord (b) Termination of Lease and Damages. Landlord may terminate this Lease, effective at such time as may be specified by written notice to Tenant, and demand (and, if such demand is refused, recover) possession of the Premises from Tenant. Tenant will remain liable to Landlord for damages in an amount equal to the Base Rent, Additional Rent and other Rent which would have been owing by Tenant for the balance of the Term had this Lease not been terminated, less the net proceeds, if any, of any reletting of the Premises by Landlord subsequent to such termination, after deducting all Landlord's expenses in connection with such recovery of possession or reletting. Landlord will be entitled to collect and receive such damages from Tenant on the days on which the Base Rent, Additional Rent and other Rent would have been payable if this Lease had not been terminated. Alternatively, at Landlord's option, Landlord will be entitled to recover from Tenant, as damages for loss of the bargain and not as a penalty, an aggregate sum equal to (i) all unpaid Base Rent, Additional Rent and other Rent for any period prior to the termination date of this Lease (including interest from the due date to the date of the award at the rate described in Section 4.5), plus any other sum of money and damages owed by Tenant to Landlord for events or actions occurring prior to the termination date; plus (ii) the present value at the time of termination (calculated at the rate commonly called the discount rate in effect at the Federal Reserve Bank of New York on the termination date) of the amount, if any, by which (A) the aggregate of the Base Rent, Additional Rent and all other Rent payable by Tenant under this Lease that would have accrued for the balance of the Term after termination (with respect to Additional Rent, such aggregate will be calculated by assuming that Expenses and Taxes for the Fiscal Year in which termination occurs and for each subsequent Fiscal Year remaining in the Term if this Lease had not been terminated will increase by 8% per year over the amount of Expenses and Taxes for the prior Fiscal Year), exceeds (B) the amount of such Base Rent, Additional Rent and other Rent which Landlord will receive for the remainder of the Term from any reletting of the Premises occurring prior to the date of the award, or if the Premises have not been relet prior to the date of the award, the amount, if any, of such Base Rent, Additional Rent and other Rent which could reasonably be recovered by reletting the Premises for the remainder of the Term at the then-current fair rental value, in either case taking into consideration loss of rent while finding a new tenant, tenant improvements and rent abatements necessary to secure a new tenant, leasing brokers' commissions and other costs which Landlord has incurred or might incur in leasing the Premises to a new tenant; plus (iii) interest on the amount described in (ii) above from the termination date to the date of the award at the rate described in Section 4.5. (c) Repossession and Reletting. Landlord may, with due process of law, re-enter and take possession of all or any part of the Premises, without additional demand or notice but not until Tenant has exhausted all cure periods as set forth in Section 20.1 above, and repossess the same and expel Tenant and any party claiming by, through or under 27 32 Tenant, and remove the effects of both using such force for such purposes as may be necessary, without being liable for prosecution for such action or being deemed guilty of any manner of trespass, and without prejudice to any remedies for arrears of Rent or right to bring any proceeding for breach of covenants or conditions. No such reentry or taking possession of the Premises by Landlord will be construed as an election by Landlord to terminate this Lease unless a written notice of such intention is given to Tenant. No notice from Landlord or notice given under a forcible entry and detainer statute or similar Laws will constitute an election by Landlord to terminate this Lease unless such notice specifically so states. Landlord reserves the right, following any reentry or reletting, to exercise its right to terminate this Lease by giving Tenant such written notice, in which event the Lease will terminate as specified in such notice. After recovering possession of the Premises, Landlord may, from time to time, but will not be obligated to, relet all or any part of the Premises for Tenant's account, for such term or terms and on such conditions and other terms as Landlord, in its discretion, determines. Landlord may make such repairs, alterations or improvements as Landlord considers appropriate to accomplish such reletting, and Tenant will reimburse Landlord upon demand for all costs and expenses, including attorneys' fees, which Landlord may incur in connection with such reletting. Landlord may collect and receive the rents for such reletting but Landlord will in no way be responsible or liable for any failure to relet the Premises or for any inability to collect any rent due upon such reletting. Regardless of Landlord's recovery of possession of the Premises, Tenant will continue to pay on the dates specified in this Lease, the Base Rent, Additional Rent and other Rent which would be payable if such repossession had not occurred, less a credit for the net amounts, if any, actually received by Landlord through any reletting of the Premises. Alternatively, at Landlord's option, Landlord will be entitled to recover from Tenant, as damages for loss of the bargain and not as a penalty, an aggregate sum equal to (i) all unpaid Base Rent, Additional Rent and other Rent for any period prior to the repossession date (including interest from the due date to the date of the award at the rate described in Section 4.5), plus (ii) the present value at the time of repossession (calculated at the rate commonly called the discount rate in effect at the Federal Reserve Bank of New York on the repossession date) of the amount, if any, by which (A) the aggregate of the Base Rent, Additional Rent and all other Rent payable by Tenant under this Lease that would have accrued for the balance of the Term after repossession (with respect to Additional Rent, such aggregate will be calculated by assuming that Expenses and Taxes for the Fiscal Year in which repossession occurs and for each subsequent Fiscal Year remaining in the Term if Landlord had not repossessed the Premises will increase by 8% per year over the amount of Expenses and Taxes for the prior Fiscal Year), exceeds (B) the amount of such Base Rent, Additional Rent and other Rent which Landlord will receive for the remainder of the Term from any reletting of the Premises occurring prior to the date of the award, or if the Premises have not been relet prior to the date of the award, the amount, if any, of such Base Rent, Additional Rent and other Rent which could reasonably be recovered by reletting the Premises for the remainder of the Term at the then-current fair rental value, in either case taking into consideration loss of rent while finding a new tenant, tenant improvements and rent abatements necessary to secure a new tenant, leasing brokers' commissions and other costs which Landlord has incurred or might incur in leasing the Premises to a new tenant; plus (iii) interest on the amount described in (ii) above from the repossession date to the date of the award at the rate described in Section 4.5. (d) Bankruptcy Relief. Nothing contained in this Lease will limit or prejudice Landlord's right to prove and obtain as liquidated damages in any bankruptcy, insolvency, receivership, reorganization or dissolution proceeding, an amount equal to the maximum allowable by any Laws governing such proceeding in effect at the time when such damages are to be proved, whether or not such amount be greater, equal or less than the amounts recoverable, either as damages or Rent, under this Lease. 21. LANDLORD'S DEFAULT AND TENANT'S REMEDIES. 21.1 Default. If Tenant believes that Landlord has breached or failed to comply with any provision of this Lease applicable to Landlord, Tenant will give written notice to Landlord describing the alleged breach or noncompliance. Landlord will not be deemed in default under this Lease if Landlord cures the breach or noncompliance within 20 days after 28 33 receipt of Tenant's notice or, if the same cannot reasonably be cured within such 20-day period, if Landlord in good faith commences to cure such breach or noncompliance within such period and then diligently pursues the cure to completion. Tenant will also send a copy of such notice to the holder of any Encumbrance of whom Tenant has been so notified in writing by Landlord, and such holder will also have the right to cure the breach or noncompliance within the period of time described above. 21.2 Remedies. If Landlord breaches or fails to comply with any provision of this Lease applicable to Landlord, and such breach or noncompliance is not cured within the period of time described in Section 21.1, then Tenant may exercise any right or remedy available to Tenant at law or in equity, except to the extent expressly waived or limited by the terms of this Lease. 21.3 Cure by Encumbrance Holder. If any act or omission by Landlord shall give Tenant the right, immediately or after the lapse of time, to cancel or terminate this Lease or to claim a partial or total eviction, Tenant shall not exercise any such right until (a) it shall have given written notice of such act or omission to each holder of any Encumbrance and (b) a reasonable period for remedying such act or omission shall have elapsed following such notice and following the time when such holder of an Encumbrance shall have become entitled under its Encumbrance to remedy the same (which shall in no event be less than the period to which Landlord would be entitled under this Lease to effect such remedy) provided such holder of an Encumbrance shall, with reasonable diligence, give Tenant notice of its intention to remedy such act or omission and shall commence and continue to act upon such intention. 22. SECURITY DEPOSIT. INTENTIONALLY DELETED. 23. BROKERS. Landlord and Tenant represent and warrant that no broker or agent negotiated or was instrumental in negotiating or consummating this Lease except the Brokers.

Each party will indemnify and hold the other harmless from all damages paid or incurred by the other resulting from any claims asserted against the other party by brokers or agents claiming through the indemnifying party. 24.

All other terms of this Lease, except this Extension Option and any Landlord's work or Allowances shall apply during the 1st Extension Term. (C) Time is of the essence of the Extension Option. (D) For the purposes of this Section 27, a "Material non-monetary default" shall mean a breach or noncompliance by Tenant of the terms and/or conditions of this Lease that causes or results in (i) a dangerous condition in the Premises or the Building, (ii) any insurance coverage required to be carried under this Lease by Landlord or Tenant with respect to the Premises or Building being jeopardized (as evidenced by a written notice from Landlord's insurance carrier), including failure to provide same, (iii) an unreasonable disturbance to another tenant, (iv) a substantial failure by Tenant to comply with Laws with respect to the Premises or use thereof.; or (v) a substantial and adverse affect on the operation of Building systems.

By the above reference to the absence of a compulsion to enter into a renewal tenancy, Landlord and Tenant do not intend to exclude renewal tenancies arising out of a tenant's exercise of a fixed option to extend its lease term. (B) If Landlord and Tenant have not agreed on Market Rent on or prior to a date thirty (30) days after the Determination Date, then each party shall appoint an arbitrator who shall be an independent, disinterested person knowledgeable in rental rates and lease transactions in the Building and other comparable buildings.

The arbitration shall be conducted according to the Commercial Arbitration Rules of the American Arbitration Association, or its successor. The three arbitrators shall determine Market Rent on or before the effective date for the Base and Additional Rent and a decision of any two of the three arbitrators shall be controlling.

(E) Time is of the essence of this Termination Option.

(B) Tenant shall exercise this Expansion Option by written notice identifying what portion of Expansion Area 1 Tenant wishes to expand (provided that Tenant must expand into all or a portion of Expansion Area 1 that becomes available on the applicable Expansion Area Availability Date); which must be received by Landlord at least two hundred seventy (270) days prior to the applicable Expansion Area Availability Date;and (C) The Lease Term for the applicable portion for Expansion Area 1 shall commence the earlier of Tenant's occupancy of Expansion Area 1 for the regular conduct of business or ninety (90) days after the later of the applicable Expansion Area Availability Date or the vacation of the current tenant from the area ("Expansion Area 1 Commencement Date") and shall expire on the Expiration Date.

Provided that Tenant has not defaulted beyond any applicable cure periods, and, providing Tenant is not in (i) monetary default or Material non-monetary default or (ii) in non-monetary, non-material default beyond any applicable cure period set forth in this Lease, under the Lease at the time of its exercise of this First Offer Right Landlord hereby grants to Tenant the one time option to lease, upon the terms and conditions hereinafter set forth, all or a portion of the tenth (10th) floor, and the fourteenth (14th) floor of the Building, and the on-going right upon the terms and conditions hereinafter set forth, all or a portion of fourth (4th), floor (each a "ROFO Area" and collectively the "ROFO Area") when it becomes "available for leasing" (as determined in accordance with subsection (A) below) during the initial Term of the Lease ("First Offer Right"). (A) The ROFO Area shall be deemed to be "available for leasing" upon, and only upon, the occurrence of one of the following events: (i) The ROFO Area is not the subject of an Existing Lease (as hereinafter defined); (ii) if the ROFO Area is subject to a right or option granted in an Existing Lease (whether to extend/renew or to expand), all of which rights or options are not exercised, the expiration of the last of such unexercised right or option; and (iii) if the ROFO Area is subject to a right or option granted in an Existing Lease, which right or option is exercised, the expiration or termination of the term of such Existing Lease or any later date upon which the term of the demise of such portion of the ROFO Area created by the exercise of such right or option expires (including any renewals or extensions thereof granted in such Existing Lease); and 35 40 (iv) As to the fourth floor only, the ROFO Area is not subject to any rights granted to a tenant (including without limitation renewal options) in a lease entered into by Landlord after Tenant has been offered and has declined to lease the ROFO Area. (B) During the initial Term of the Lease, prior to Landlord's leasing all or a potion of the ROFO Area to a party other than a tenant leasing premises in the ROFO Area as of the Date, and subject to the rights of existing tenants in the ROFO Area as of the Date, Landlord shall give Tenant a written notice (the "Offer Notice") setting forth the availability date and the portion of the ROFO Area being offered to Tenant (the "the ROFO Area Availability Date"). The ROFO Area Availability Date shall not be less than sixty (60) days after the date such notice is given by Landlord. The Base and Additional Rent for the ROFO Area shall be Market Rent as determined in Section 28 above and the ROFO Area shall be delivered in "as-is" condition; and (C) Tenant's right to lease the ROFO Area on the terms described in the applicable Offer Notice shall be exercisable by written notice from Tenant to Landlord given not later than ten (10) days after the Offer Notice is delivered. Tenant shall be deemed to have declined a lease for the offered portion of the ROFO Area if its acceptance is delayed or if the acceptance changes any term or condition of the Offer Notice. If such right is not so exercised, then at such time Tenant's First Offer Right for the offered portion of the ROFO Area, except for any ROFO Area located on the 4th floor, shall be null and void and of no further force or effect and Landlord shall have the right to lease the all or any portion of the offered portion of the ROFO Area to a third party on the same or any other terms and conditions, whether or not such terms and conditions are more or less favorable than those offered to Tenant. As to any ROFO Area located on the 4th floor, if Tenant declines or is deemed to decline a lease as set forth above, then for the following one hundred eighty (180) days Landlord shall have the right to Lease said portion of the ROFO Area located on the 4th floor to a third party on materially the same terms as those offered to Tenant and otherwise shall follow the procedure set forth in subsection B above; and (D) If Tenant has validly exercised this First Offer Right for the offered portion of the ROFO Area in accordance with the terms hereof, Landlord and Tenant, within thirty (30) days after request by either party hereto, shall enter into a written amendment to this Lease confirming the terms, conditions and provisions applicable to such portion of the ROFO Area as determined in accordance herewith; and (E) The Lease Term for the ROFO Area shall commence the earlier of Tenant's occupancy of the ROFO Premises for the regular conduct of business or ninety (90) days after Landlord's delivery of same and shall expire on the Expiration Date; and (F) As used herein, the term "Existing Lease" shall mean (i) a lease (other than this Lease) of any space in the Building in effect as of the date hereof (including extensions and renewals thereof pursuant to options granted therein or otherwise), whether or not the term of such lease has yet commenced and (ii) any lease in effect as of the date of the commencement of the initial Term of the Lease, whether or not the term of such lease has then commenced. In the event two leases are in effect for any portion of the the ROFO Area (for example, the term of a lease which is now in effect for a portion of the the ROFO Area will soon expire, and another lease covering part or all of such space has already been executed with a new tenant for a term commencing after the expiration of the term of the former lease), only one of such leases shall be an Existing Lease. In such case, the Existing Lease shall be determined by comparing the dates upon which the respective terms of such two leases end, and the lease with the later expiration date shall be deemed to be the Existing Lease and the other lease shall be disregarded.; and (G) Time is of the essence of this First Offer Right; and (H) If Tenant leases this the ROFO Area under this First Offer Right, Tenant shall have the right to extend the term of the Lease for the ROFO Area upon the same terms and conditions in Section 27 above and to terminate the Lease for the ROFO area on the same terms and conditions in Section 29 above; and 36 41 (I) Notwithstanding what is set forth above, Landlord shall have the right to extend the term of any lease for any tenant occupying any portion of the ROFO Area which lease is in effect as of the Date, whether by exercise of a lease option or otherwise; and (J) Notwithstanding what is set forth above, Tenant's First Offer Right is subordinate to the rights of existing tenants as of the Date in the ROFO Area, which, to the best of Landlord's knowledge as of the Date, are those rights set forth in Exhibit H attached and incorporated herein. (K) For the purposes of this Section 31, a "Material non-monetary default" shall mean a breach or noncompliance by Tenant of the terms and/or conditions of this Lease that causes or results in (i) a dangerous condition in the Premises or the Building, (ii) any insurance coverage required to be carried under this Lease by Landlord or Tenant with respect to the Premises or Building being jeopardized (as evidenced by a written notice from Landlord's insurance carrier),, including failure to provide same, (iii) an unreasonable disturbance to another tenant, (iv) a substantial failure by Tenant to comply with Laws with respect to the Premises or use thereof.; or (v) a substantial and adverse affect on the operation of Building systems. This First Offer Right applies to Tenant only and shall be void if Tenant fails to exercise it precisely according to each and all of the conditions stated above, or if Tenant assigns the Lease or sublets the Premises or otherwise transfers all or part of its interest in the Lease or the Premises, except as allowed under Section 15.7 of the Lease. 32. SIGNAGE. During the Term of this Lease, including any renewal terms, provided that (i) Tenant is not in default of any of the terms or conditions of this Lease, (ii) Tenant has not assigned the Lease or sublet the Premises or otherwise transferred all or part of its interest in the Lease or the Premises, and (iii) Tenant is in occupancy of the entire Premises, Landlord shall provide Tenant, at Landlord's sole cost and expense, with identification signage on a monument sign in the exterior Plaza ("Monument Signage"), with ground floor lobby signage ("Lobby Signage") and with elevator button signage within the elevator cabs for the floors where Tenant occupies the entire floor ("Elevator Button Signage").

In addition, Landlord shall provide company and individual name listings for Tenant's employees, not to exceed fifty (50) names, in the Building's computerized directory, and Building standard Tenant identification signage in the elevator lobbies of the floors occupied by Tenant. 33. YEAR 2000 COMPLIANCE. Landlord shall be responsible for Year 2000 compliance of all services furnished by Landlord to Tenant pursuant to this Lease. If Landlord obtains actual knowledge that any of those services are not Year 2000 compliant, Landlord shall promptly take such measures as are appropriate to cause those services to become Year 2000 compliant, but Landlord shall have no obligations with respect to any failure of its services that arise because third party systems not under its control are not Year 2000 compliant 34. GENERATOR. Provided that Tenant is not in Default, throughout the Term of the Lease, including any Extension Term, Landlord shall provide Tenant with approximately 200-300 exclusive, restricted access rentable square feet 37 42 in the Building in a location to be determined by Landlord to house an emergency back-up electrical generator to service the Premises ("Generator Space") and for no other use, at Landlord's expense during the Term or any extension thereof. Tenant's occupancy and use of the Generator Space shall be pursuant to all of the terms and conditions of this Lease except that Tenant shall not be required to pay Base or Additional Rent for the Generator Space.

Tenant agrees that it will comply with all Laws governing, and all reasonable procedures established by Landlord for, the use, abatement, removal, storage, disposal or transport of any gasoline, fuel oil, propane or other fuels used to power the generator ("Fuels") and any substances, chemicals or materials declared to be, or regulated as, hazardous or toxic under any applicable Laws ("Hazardous Substances") and any required or permitted alteration, repair, maintenance, restoration, removal or other work in or about the Premises or Building that involves or affects any Fuels or Hazardous Substances. Upon the expiration of the Lease or sooner termination hereof, Tenant shall remove the generator, transfer switch, fuel storage tank and their accompanying Improvements (excluding any electrical panels, electrical meters, sprinklers or vents) and shall repair and restore the Generator Space to its original condition, normal wear and tear excepted. Tenant will indemnify and hold Landlord harmless from and against any and all claims, costs and liabilities (including reasonable attorney's fees) arising out of or in connection with any breach by Tenant of its covenants under this Section 34. Tenant's obligations under this Section will survive the expiration or early termination of the Term.

Failure to advise Landlord in writing within one year of the Commencement Date of any latent defects shall result in a waiver of any claims regarding said defects by Tenant. No promises to alter, remodel, or improve the Premises or Building and no representations concerning the condition of the Premises or Building have been made by Landlord to Tenant other than as may be expressly stated in the Lease (including this Work Letter). 6. Early Access. Tenant will not be entitled to exclusive possession of the Premises until Landlord's Work is completed. Landlord may, in its discretion, permit Tenant to enter the Premises prior to the Start Date so that Tenant may do such work as may be required to prepare the Premises for Tenant's Work. If Landlord permits such entry prior to the Start Date, Tenant shall work in harmony with Landlord and will not interfere with the performance of Landlord's Work, or with the work of any other tenant or occupant. If at any time such access causes or threatens to cause disharmony or interference, including labor disharmony, Landlord will have the right to immediately withdraw such permission. At all times while Tenant is in occupation of the Premises prior to the Commencement Date (including the Tenant Finish Period), B-3 50 Tenant will be subject to and will comply with all of the terms and provisions of the Lease, except that no Base Rent or Additional Rent will be payable by Tenant prior to the Commencement Date. 7. Landlord's Approval.

Such submittal will include one (1) sepia, five (5) sets of blueline prints and three (3) sets of those specifications not shown on the drawings. If the submitted materials are not acceptable to Landlord, Landlord will so notify Tenant by returning the sepia with required changes noted within five (5) business days of receipt of same. If Landlord so notifies Tenant of any required change to the Preliminary Plans, Tenant will cause the same to be revised according to the returned sepia and resubmitted to Landlord within seven (7) days after receipt of such notice. Within fifteen (15) days after Landlord notifies Tenant of Landlord's approval of the Preliminary Plans, Tenant, at its expense, will cause the Construction Documents to be prepared and submitted to Landlord for its approval. Such submittal will include one sepia, five (5) sets of blueline prints, three (3) sets of specifications and a complete color and finish board for Tenant's Work. The Construction Documents must strictly conform to the Preliminary Plans approved by Landlord and must be in all respects sufficient for the purpose of obtaining a building permit for Tenant's Work. If the submitted materials are not acceptable to Landlord, Landlord will so notify Tenant by returning the sepia with required changes noted within five (5) business days of receipt of same If required by Landlord, Tenant will cause the Construction Documents to be resubmitted to Landlord for its approval within seven (7) days after Landlord notifies Tenant of any required changes. Tenant's Work will not commence prior to Landlord's approval of the Construction Documents. If the Landlord fails to deliver to Tenant Landlord's written approval or its written request for revisions within five (5) business days after Landlord receives any required revisions to them, Tenant will receive a credit against Base Rent beginning on the Commencement Date equal to one day's Base Rent for each day subsequent to the fifth (5th) business day after Tenant's submittal until the day of Landlord's response. Except as provided in Paragraph 2 above, no delays in the design or performance of Tenant's Work will change the Start Date or the Commencement Date. Upon completion of Tenant's Work, Tenant will provide Landlord a complete set of reproducible as-built B-4 51 plans of the Premises. If Tenant fails to provide such plans, Landlord may obtain them, directly or by field verification, and charge Tenant for all costs incurred by Landlord in doing so. No approval by Landlord of the Preliminary Plans, the Construction Documents or any revisions to them will constitute a representation or warranty by Landlord as to the adequacy or sufficiency of such plans, or the improvements to which they relate, for any use, purpose or condition, but such approval will merely be the consent of Landlord to the construction or installation of improvements in the Premises according to such plans. 9. Tenant's Work. During the Tenant Finish Period, Tenant, at its expense, will construct or cause to be constructed in the Premises all of Tenant's Work according to the Construction Documents approved by Landlord.

Landlord's Allowances Landlord agrees to pay Tenant the "Allowances" as defined in Paragraph 1(j) of this Exhibit B above, to be applied to the cost of designing and performing Tenant's Work, in progress payments after the commencement of the Tenant Finish Period.

Such progress payments will be made payable to Tenant and Contractor, and will be for the amount of the submitted invoices, less a ten percent (10%) retainage. As a condition precedent to Landlord's issuing any such progress payment subsequent to the first such progress payment, Tenant will deliver to Landlord original lien waivers from Contractor B-8 55 and any applicable subcontractor or supplier indicating the claims for mechanics' or materialmen's liens with respect to the labor and materials reflected in the invoiced submitted for the immediately preceding progress payment have been waived. A further condition precedent to Landlord's issuing the last such payment for the amount of the retainage will be that Landlord has received from Tenant (either prior to or simultaneously with the issuance of such final payment) the following: (1) written notice from Contractor and Tenant`s Architect (or other evidence satisfactory or Landlord) that Tenant's Work has been completed (including completion of any punch list items); (2) final and unconditional original lien waivers from Contractor and all subcontractors, suppliers, materialmen and other parties who performed labor at, or supplied materials to, the Premises in connection with Tenant's Work; and (3) a copy of the certificate of occupancy for the Premises issued by the appropriate governmental authorities.

General. Failure by either party to pay any amounts due under this Work Letter will have the same effect as failure to pay Rent under the Lease as to Tenant and a Landlord's default under the Lease as to Landlord, and such failure or either parties failure to perform any of its other obligations under this Work Letter will constitute a Default under Section 20.1 of the Lease as to Tenant and Section 21 of the Lease as to Landlord, entitling the other party to all of its remedies under the Lease as well as all remedies otherwise available to the other party.
