LEASE

This Lease Agreement (this "Lease") is entered into as of September , 2006, between HI/OCC, INC., a Minnesota corporation ("Landlord"), and PDSHEART, Inc., a Delaware corporation ("Tenant").

1. Definitions and Basic Provisions. The definitions and basic provisions set forth in the Basic Lease Information (the "Basic Lease Information") executed by Landlord and Tenant contemporaneously herewith are incorporated herein by reference for all purposes. Additionally, the following terms shall have the following meanings when used in this Lease: "Affiliate" means any person or entity which, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with the party in question; "Building's Structure" means the Building's exterior walls, roof, elevator shafts, footings, foundations, structural portions of load-bearing walls, structural floors and subfloors, and structural columns and beams; "Building's Systems" means the Building's HVAC, life-safety, plumbing, electrical, and mechanical systems; "Including" means including, without limitation; "Laws" means all federal, state, and local laws, ordinances, rules and regulations, all court orders, governmental directives, and governmental orders and all interpretations of the foregoing, and all restrictive covenants affecting the Project, and "Law" shall mean any of the foregoing; "Tenant's Off-Premises Equipment" means any of Tenant's equipment or other property that may be located on or about the Project (other than inside the Premises); and "Tenant Party" means any of the following persons: Tenant; any assignees claiming by, through, or under Tenant; any subtenants claiming by, through, or under Tenant; and any of their respective agents, contractors, employees, licensees, guests and invitees.

2. Lease Grant. Subject to the terms of this Lease, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises.

3. Tender of Possession. Landlord and Tenant presently anticipate that possession of the Premises will be tendered to Tenant in the condition required by this Lease on or about October 1, 2006 (the "Estimated Delivery Date"). If Landlord is unable to tender possession of the Premises in such condition to Tenant by the Estimated Delivery Date, then, subject to the exceptions in this paragraph, (a) the validity of this Lease shall not be affected or impaired thereby, (b) Landlord shall not be in default hereunder or be liable for damages therefor, and (c) Tenant shall accept possession of the Premises when Landlord tenders possession thereof to Tenant. If Landlord is unable to tender possession of the Premises in the condition required by this lease on to Tenant by the thirtieth day following the Estimated Delivery Date (the "Required Delivery Date"), then for each day after the Required Delivery Date that Landlord has failed to tender possession of the Premises to Tenant, provided such delay has not been caused by Tenant, Tenant shall be entitled to one free day of Base Rent once this lease commences. In the event that Landlord is unable to tender possession of the Premises to Tenant within 120 days following the Estimated Delivery Date, then Tenant, at its option may terminate this Lease.

By occupying the Premises, Tenant shall be deemed to have accepted the Premises in their condition as of the date of such occupancy, subject to the performance of punch-list items that remain to be performed by Landlord, if any. Prior to occupying the Premises, Tenant shall execute and deliver to Landlord a letter substantially in the form of Exhibit E hereto confirming (1) the Commencement Date and the expiration date of the initial Term, (2) that Tenant has accepted the Premises, and (3) that Landlord has performed all of its obligations with respect to the Premises (except for punch-list items specified in such letter); however, the failure of the parties to execute such letter shall not defer the Commencement Date or otherwise invalidate this Lease. Occupancy of the Premises by Tenant prior to the Commencement Date shall be subject to all of the provisions of this Lease excepting only those requiring the payment of Basic Rent, Additional Rent, Taxes and Electrical Costs (each as defined herein). Notwithstanding anything herein to the contrary, Tenant shall have access to

the Premises two (2) weeks prior to the Commencement Date for furniture delivery and telecom set-up, subject to all the terms and conditions of this Lease other than those requiring payment of Basic Rent, Taxes, and Operating Costs.

4. Rent.

(a) Payment. Tenant shall timely pay to Landlord Rent, without notice, demand, deduction or set off (except as otherwise expressly provided herein), by good and sufficient check drawn on a national banking association at Landlord's address provided for in this Lease or as otherwise specified by Landlord and shall be accompanied by all applicable state and local sales or use taxes. The obligations of Tenant to pay Basic Rent and other sums to Landlord and the obligations of Landlord under this Lease are independent obligations. Basic Rent, adjusted as herein provided, shall be payable monthly in advance. The first monthly installment of Basic Rent shall be payable contemporaneously with the execution of this Lease; thereafter, Basic Rent shall be payable on the first day of each month beginning on the first day of the second full calendar month of the Term. The monthly Basic Rent for any partial month at the beginning of the Term shall equal the product of 1/365 of the annual Basic Rent in effect during the partial month and the number of days in the partial month and shall be due on the Commencement Date. Payments of Basic Rent for any fractional calendar month at the end of the Term shall be similarly prorated. Tenant shall pay Additional Rent at the same time and in the same manner as Basic Rent.

(b) Operating Costs; Taxes; Electrical Costs.

(1) Tenant shall pay to Landlord the amount (per each rentable square foot in the Premises) ("Additional Rent") by which the annual Operating Costs (defined below) per rentable square foot in the Building exceed the Expense Stop (per rentable square foot in the Building). Landlord may make a good faith estimate of the Additional Rent to be due by Tenant for any calendar year or part thereof during the Term. During each calendar year or partial calendar year of the Term (after the base year, if the Expense Stop is calculated on a base year basis), Tenant shall pay to Landlord, in advance concurrently with each monthly installment of Basic Rent, an amount equal to the estimated Additional Rent for such calendar year or part thereof divided by the number of months therein. From time to time, Landlord may estimate and re-estimate the Additional Rent to be due by Tenant and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Additional Rent payable by Tenant shall be appropriately adjusted in accordance with the estimations so that, by the end of the calendar year in question, Tenant shall have paid all of the Additional Rent as estimated by Landlord. Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Operating Costs are available for each calendar year.

(2) The term "Operating Costs" shall mean all expenses and disbursements (subject to the limitations set forth below) that Landlord incurs in connection with the ownership, operation, and maintenance of the Project, determined in accordance with sound accounting principles consistently applied, including the following costs: (A) wages and salaries of all on-site employees at or below the grade of senior building manager engaged in the operation, maintenance or security of the Project (together with Landlord's reasonable allocation of expenses of off-site employees at or below the grade of senior building manager who perform a portion of their services in connection with the operation, maintenance or security of the Project), including taxes, insurance and benefits relating thereto; (B) all supplies and materials used in the operation, maintenance, repair, replacement, and security of the Project; (C) costs for improvements made to the Project which, although capital in nature, are expected to reduce the normal operating costs (including all utility costs) of the Project, as amortized using a commercially reasonable interest rate over the time period reasonably estimated by

Landlord to recover the costs thereof taking into consideration the anticipated cost savings, as determined by Landlord using its good faith, commercially reasonable judgment, as well as capital improvements made in order to comply with any Law hereafter promulgated by any governmental authority or any interpretation hereafter rendered with respect to any existing Law, as amortized using a commercially reasonable interest rate over the useful economic life of such improvements as determined by Landlord in its reasonable discretion; (D) cost of all utilities, except Electrical Costs and the cost of other utilities reimbursable to Landlord by the Project's tenants other than pursuant to a provision similar to this Section 4(b); (E) insurance expenses; (F) repairs, replacements, and general maintenance of the Project; (G) fair market rental and other costs with respect to the management office for the Building; and (H) service, maintenance and management contracts with independent contractors for the operation, maintenance, management, repair, replacement, or security of the Project (including alarm service, window cleaning, and elevator maintenance). If the Building is part of a multi-building office complex (the "Complex"), Operating Costs, Taxes and Electrical Costs for the Complex may be prorated among the Project and the other buildings of the Complex, as reasonably determined by Landlord.

Operating Costs shall not include costs for (i) capital improvements made to the Building (including any expense that would be considered capital in nature under Generally Accepted Accounting Principals ("GAAP")), other than capital improvements described in Section 4(b)(2)(C) and except for items which are generally considered maintenance and repair items, such as painting of common areas, replacement of carpet in elevator lobbies, and the like; (ii) repair, replacements and general maintenance paid by proceeds of insurance or by Tenant or other third parties; (iii) interest, amortization or other payments on loans to Landlord; (iv) depreciation; (v) leasing commissions; (vi) legal expenses for services, other than those that benefit the Project tenants generally (e.g., tax disputes); (vii) renovating or otherwise improving space for occupants of the Project or vacant space in the Project; (viii) Taxes; and (ix) federal income taxes imposed on or measured by the income of Landlord from the operation of the Project. If the Expense Stop is calculated on a base year basis, Operating Costs for the base year only shall not include market-wide labor-rate increases due to extraordinary circumstances, including boycotts and strikes; utility rate increases due to extraordinary circumstances, including conservation surcharges, boycotts, embargos or other shortages; or amortized costs relating to capital improvements.

(3) Tenant shall also pay Tenant's Proportionate Share of any increase in Taxes for each year and partial year falling within the Term over the Taxes for the Base Tax Year. Tenant shall pay Tenant's Proportionate Share of Taxes in the same manner as provided above for Tenant's Proportionate Share of Operating Costs. "Taxes" shall mean taxes, assessments, and governmental charges or fees whether federal, state, county or municipal, and whether they be by taxing districts or authorities presently taxing or by others, subsequently created or otherwise, and any other taxes and assessments (including non-governmental assessments for common charges under a restrictive covenant or other private agreement that are not treated as part of Operating Costs) now or hereafter attributable to the Project (or its operation), excluding, however, penalties and interest thereon and federal and state taxes on income (if the present method of taxation changes so that in lieu of or in addition to the whole or any part of any Taxes, there is levied on Landlord a capital tax directly on the rents received therefrom or a franchise tax, assessment, or charge based, in whole or in part, upon such rents for the Project, then all such taxes, assessments, or charges, or the part thereof so based, shall be deemed to be included within the term "Taxes" for purposes hereof). Taxes shall include the costs of consultants retained in an effort to lower taxes and all costs incurred in disputing any taxes or in seeking to lower the tax valuation of the Project. For property tax purposes,

Tenant waives all rights to protest or appeal the appraised value of the Premises, as well as the Project, and all rights to receive notices of reappraisement.

(4) Tenant shall also pay to Landlord Tenant's Proportionate Share of the cost of all electricity used by the Project ("Electrical Costs"). Such amount shall be payable in monthly installments on the Commencement Date and on the first day of each calendar month thereafter. Each installment shall be based on Landlord's estimate of the amount due for each month. From time to time during any calendar year, Landlord may estimate or re-estimate the Electrical Costs to be due by Tenant for that calendar year and deliver a copy of the estimate or re-estimate to Tenant. Thereafter, the monthly installments of Electrical Costs payable by Tenant shall be appropriately adjusted in accordance with the estimations.

(5) By April 1 of each calendar year, or as soon thereafter as practicable, Landlord shall furnish to Tenant a statement of Operating Costs and Electrical Costs for the previous year, in each case adjusted as provided in Section 4(b)(6), and of the Taxes for the previous year (the "Operating Costs and Tax Statement"). If Tenant's estimated payments of Operating Costs, Electrical Costs or Taxes under this Section 4(b) for the year covered by the Operating Costs and Tax Statement exceed Tenant's Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Landlord shall promptly credit or reimburse Tenant for such excess; likewise, if Tenant's estimated payments of Operating Costs, Electrical Costs or Taxes under this Section 4(b) for such year are less than Tenant's Proportionate Share of such items as indicated in the Operating Costs and Tax Statement, then Tenant shall promptly pay Landlord such deficiency.

(6) With respect to any calendar year or partial calendar year in which the Building is not occupied to the extent of 95% of the rentable area thereof, or Landlord is not supplying services to 95% of the rentable area thereof, the Operating Costs and Electrical Costs for such period shall, for the purposes hereof, be increased to the amount which would have been incurred had the Building been occupied to the extent of 95% of the rentable area thereof and Landlord had been supplying services to 95% of the rentable area thereof.

5. Delinquent Payment; Handling Charges. All past due payments required of Tenant hereunder shall bear interest from the date due until paid at the lesser of eighteen percent per annum or the maximum lawful rate of interest (such lesser amount is referred to herein as the "Default Rate"); additionally, Landlord, in addition to all other rights and remedies available to it, may charge Tenant a fee equal to five percent of the delinquent payment to reimburse Landlord for its cost and inconvenience incurred as a consequence of Tenant's delinquency. In no event, however, shall the charges permitted under this Section 5 or elsewhere in this Lease, to the extent they are considered to be interest under applicable Law, exceed the maximum lawful rate of interest. Notwithstanding the foregoing, the late fee referenced above shall not be charged with respect to the first occurrence (but not any subsequent occurrence) during any 12-month period that Tenant fails to make payment when due, until five days after Landlord delivers written notice of such delinquency to Tenant.

6. Security Deposit. Contemporaneously with the execution of this Lease, Tenant shall pay to Landlord the Security Deposit, which shall be held by Landlord to secure Tenant's performance of its obligations under this Lease. The Security Deposit is not an advance payment of Rent or a measure or limit of Landlord's damages upon an Event of Default (as defined herein). Landlord may, from time to time following an Event of Default and without prejudice to any other remedy, use all or a part of the Security Deposit to perform any obligation Tenant fails to perform hereunder. Following any such application of the Security Deposit, Tenant shall pay to Landlord on demand the amount so applied in order to restore the Security Deposit to its original amount. Provided that Tenant has performed all of its obligations hereunder, Landlord shall, within 30 days after the Term ends, return to Tenant the portion of the Security Deposit which was not applied to satisfy Tenant's obligations. The Security

Deposit may be commingled with other funds, and no interest shall be paid thereon. If Landlord transfers its interest in the Premises and the transferee assumes Landlord's obligations under this Lease, then Landlord may assign the Security Deposit to the transferee and Landlord thereafter shall have no further liability for the return of the Security Deposit.

7. Landlord's Obligations.

(a) Services. Landlord shall use all reasonable efforts to furnish to Tenant (1) water at those points of supply provided for general use of tenants of the Building; (2) heated and refrigerated air conditioning ("HVAC") as appropriate, at such temperatures and in such amounts as are standard for comparable buildings in the vicinity of the Building; (3) janitorial service to the Premises on weekdays, other than holidays, for Building-standard installations and such window washing as may from time to time be reasonably required; (4) elevators for ingress and egress to the floor on which the Premises are located, in common with other tenants, provided that Landlord may reasonably limit the number of operating elevators during non-business hours and holidays; and (5) electrical current during normal business hours for equipment that does not require more than 110 volts and whose electrical energy consumption does not exceed normal office usage. Landlord shall maintain the common areas of the Building in reasonably good order and condition, except for damage caused by a Tenant Party. Notwithstanding anything herein to the contrary, Landlord shall charge Tenant $100.00 per month throughout the Term to run HVAC service in the Premises 7 days per week, and 24 hours per day, which sum is to be paid by Tenant as Additional Rent.

(b) Excess Utility Use. Landlord shall not be required to furnish electrical current for equipment that requires more than 110 volts or other equipment whose electrical energy consumption exceeds normal office usage. If Tenant's requirements for or consumption of electricity exceed the electricity to be provided by Landlord as described in Section 7(a), Landlord shall, at Tenant's expense, make reasonable efforts to supply such service through the then-existing feeders and risers serving the Building and the Premises, and Tenant shall pay to Landlord the cost of such service within 30 days after Landlord has delivered to Tenant an invoice therefor. Landlord may determine the amount of such additional consumption and potential consumption by any verifiable method, including installation of a separate meter in the Premises installed, maintained, and read by Landlord, at Tenant's expense. Tenant shall not install any electrical equipment requiring special wiring or requiring voltage in excess of 110 volts unless approved in advance by Landlord, which approval shall not be unreasonably withheld. Tenant shall not install any electrical equipment requiring voltage in excess of Building capacity unless approved in advance by Landlord, which approval may be withheld in Landlord's sole discretion. The use of electricity in the Premises shall not exceed the capacity of existing feeders and risers to or wiring in the Premises. Any risers or wiring required to meet Tenant's excess electrical requirements shall, upon Tenant's written request, be installed by Landlord, at Tenant's cost, if, in Landlord's judgment, the same are necessary and shall not cause permanent damage to the Building or the Premises, cause or create a dangerous or hazardous condition, entail excessive or unreasonable alterations, repairs, or expenses, or interfere with or disturb other tenants of the Building. If Tenant uses machines or equipment in the Premises which affect the temperature otherwise maintained by the air conditioning system or otherwise overload any utility, Landlord may install supplemental air conditioning units or other supplemental equipment in the Premises, and the cost thereof, including the cost of installation, operation, use, and maintenance, shall be paid by Tenant to Landlord within 30 days after Landlord has delivered to Tenant an invoice therefor.

(c) Restoration of Services; Abatement. Landlord shall use reasonable efforts to restore any service required of it that becomes unavailable; however, such unavailability shall not, provided such services are restored in five (5) business days following Landlord's receipt of written notice regarding such unavailability, render Landlord liable for any damages caused thereby, be a

constructive eviction of Tenant, constitute a breach of any implied warranty, or, except as provided in the next sentence, entitle Tenant to any abatement of Tenant's obligations hereunder. If, however, Tenant is prevented from using the Premises because of the unavailability of any such service for a period of five (5) consecutive business days following Landlord's receipt from Tenant of a written notice regarding such unavailability, the restoration of which is within Landlord's reasonable control, and such unavailability was not caused by a Tenant Party or a governmental directive, then Tenant shall, as its exclusive remedy be entitled to a reasonable abatement of Rent for each consecutive day (after such 5-day period) that Tenant is so prevented from using the Premises.

8. Improvements; Alterations; Repairs; Maintenance.

(a) Improvements; Alterations. Improvements to the Premises shall be installed at Tenant's expense only in accordance with plans and specifications which have been previously submitted to and approved in writing by Landlord, which approval shall be governed by the provisions set forth in this Section 8(a). No alterations or physical additions in or to the Premises may be made without Landlord's prior written consent, which shall not be unreasonably withheld or delayed; however, Landlord may withhold its consent to any alteration or addition that would adversely affect (in the reasonable discretion of Landlord) the (1) Building's Structure or the Building's Systems (including the Building's restrooms or mechanical rooms), (2) exterior appearance of the Building, (3) appearance of the Building's common areas or elevator lobby areas, or (4) provision of services to other occupants of the Building. Tenant shall not paint or install lighting or decorations, signs, window or door lettering, or advertising media of any type visible from the exterior of the Premises without the prior written consent of Landlord, which consent may be withheld in Landlord's sole and absolute discretion. All alterations, additions, and improvement shall be constructed, maintained, and used by Tenant, at its risk and expense, in accordance with all Laws; Landlord's consent to or approval of any alterations, additions or improvements (or the plans therefor) shall not constitute a representation or warranty by Landlord, nor Landlord's acceptance, that the same comply with sound architectural and/or engineering practices or with all applicable Laws, and Tenant shall be solely responsible for ensuring all such compliance.

(b) Repairs; Maintenance. Tenant shall maintain the Premises in a clean, safe, and operable condition, and shall not permit or allow to remain any waste or damage to any portion of the Premises. Additionally, Tenant, at its sole expense, shall repair, replace and maintain in good condition and in accordance with all Laws and the equipment manufacturer's suggested service programs, all portions of the Premises, Tenant's Off-Premises Equipment and all areas, improvements and systems exclusively serving the Premises. Tenant shall repair or replace, subject to Landlord's direction and supervision, any damage to the Building caused by a Tenant Party. If Tenant fails to make such repairs or replacements within 15 days after the occurrence of such damage, then Landlord may make the same at Tenant's cost. If any such damage occurs outside of the Premises, then Landlord may elect to repair such damage at Tenant's expense, rather than having Tenant repair such damage. The cost of all maintenance, repair or replacement work performed by Landlord under this Section 8 shall be paid by Tenant to Landlord within 30 days after Landlord has invoiced Tenant therefor.

(c) Performance of Work. All work described in this Section 8 shall be performed only by Landlord or by contractors and subcontractors approved in writing by Landlord. Tenant shall cause all contractors and subcontractors to procure and maintain insurance coverage naming Landlord, Landlord's property management company and Landlord's asset management company as additional insureds against such risks, in such amounts, and with such companies as Landlord may reasonably require. Tenant shall provide Landlord with the identities, mailing addresses and telephone numbers of all persons performing work or supplying materials prior to beginning such construction and Landlord may post on and about the Premises notices of non-responsibility

pursuant to applicable Laws. All such work shall be performed in accordance with all Laws and in a good and workmanlike manner so as not to damage the Building (including the Premises, the Building's Structure and the Building's Systems). All such work which may affect the Building's Structure or the Building's Systems must be approved by the Building's engineer of record, at Tenant's expense and, at Landlord's election, must be performed by Landlord's usual contractor for such work. All work affecting the roof of the Building must be performed by Landlord's roofing contractor and no such work will be permitted if it would void or reduce the warranty on the roof.

(d) Mechanic's Liens. All work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party shall be deemed authorized and ordered by Tenant only, and Tenant agrees to promptly pay all sums of money in respect of any labor, services, materials, supplies or equipment furnished or alleged to have been furnished to Tenant or anyone holding the Premises or any part thereof, through, or under Tenant in, at or about the Premises, or furnished to Tenant's agents, employees, contractors or subcontractors, which may be secured by any mechanic's, material supplier's or other type of lien against any part of the Project or Landlord's interest therein (a "Lien"). Tenant shall notify Landlord of the filing of any Lien within three days after receiving notice of such filing. If Tenant fails, within 20 days after the date of the filing of the Lien, to discharge such Lien or pursuant to Minn. Stat. § 514.10 deposit into court a sum determined by the court, Landlord may, but shall not be required or expected to, remove such Lien in such manner as Landlord may, in its sole discretion, determine, and the full cost thereof, together with all Landlord's fees and costs, including attorney fees, shall be due and payable by Tenant to Landlord immediately upon Tenant's receipt of Landlord's notice therefor. Tenant acknowledges that Landlord may post notice on the Premises of non-responsibility for such Liens and, in such event, Tenant shall so advise all contractors, materialmen, suppliers and other persons performing work or providing services and/or supplies to the Premises on behalf of Tenant. Landlord and Tenant acknowledge and agree that their relationship is and shall be solely that of "landlord-tenant" (thereby excluding a relationship of "owner-contractor," "owner-agent" or other similar relationships). Accordingly, all materialmen, contractors, artisans, mechanics, laborers and any other persons now or hereafter contracting with Tenant, any contractor or subcontractor of Tenant or any other Tenant Party for the furnishing of any labor, services, materials, supplies or equipment with respect to any portion of the Premises, at any time from the date hereof until the end of the Term, are hereby charged with notice that they look exclusively to Tenant to obtain payment for same. Nothing herein shall be deemed a consent by Landlord to any liens being placed upon the Premises, the Project or Landlord's interest therein due to any work performed by or for Tenant or deemed to give any contractor or subcontractor or materialman any right or interest in any funds held by Landlord to reimburse Tenant for any portion of the cost of such work. Tenant shall defend, indemnify and hold harmless Landlord and its agents and representatives from and against all claims, demands, causes of action, suits, judgments, damages and expenses (including attorneys' fees) in any way arising from or relating to the failure by any Tenant Party to pay for any work performed, materials furnished, or obligations incurred by or at the request of a Tenant Party. This indemnity provision shall survive termination or expiration of this Lease.

9. Use. Tenant shall continuously occupy and use the Premises only for the Permitted Use and shall comply with all Laws relating to the use, condition, access to, and occupancy of the Premises and will not commit waste, overload the Building's Structure or the Building's Systems or subject the Premises to use that would damage the Premises. The population density within the Premises as a whole shall at no time exceed one person for each 300 rentable square feet in the Premises. Tenant shall not conduct second or third shift operations within the Premises, however, Tenant may use the Premises after normal business hours, so long as Tenant is not generally conducting business from the Premises after normal business hours. Notwithstanding anything in this Lease to the contrary, as

between Landlord and Tenant, (a) Tenant shall bear the risk of complying with Title III of the Americans With Disabilities Act of 1990, any state laws governing handicapped access or architectural barriers, and all rules, regulations, and guidelines promulgated under such laws, as amended from time to time (the "Disabilities Acts") in the Premises, and (b) Landlord shall bear the risk of complying with the Disabilities Acts in the common areas of the Building, other than compliance that is necessitated by the use of the Premises for other than the Permitted Use or as a result of any alterations or additions, including any initial tenant improvement Work, made by or on behalf of a Tenant Party (which risk and responsibility shall be borne by Tenant). The Premises shall not be used for any use which is disreputable, creates extraordinary fire hazards, or results in an increased rate of insurance on the Building or its contents, or for the storage of any Hazardous Materials (other than typical office supplies [e.g., photocopier toner] and then only in compliance with all Laws). Tenant shall not use any substantial portion of the Premises for a "call center," any other telemarketing use, or any credit processing use. If, because of a Tenant Party's acts or because Tenant vacates the Premises, the rate of insurance on the Building or its contents increases, then such acts shall be an Event of Default, Tenant shall pay to Landlord the amount of such increase on demand, and acceptance of such payment shall not waive any of Landlord's other rights. Tenant shall conduct its business and control each other Tenant Party so as not to create any nuisance or unreasonably interfere with other tenants or Landlord in its management of the Building.

10. Assignment and Subletting.

(a) Transfers. Except as provided in Section 10(h), Tenant shall not, without the prior written consent of Landlord, (1) assign, transfer, or encumber this Lease or any estate or interest herein, whether directly or by operation of law, (2) permit any other entity to become Tenant hereunder by merger, consolidation, or other reorganization, (3) if Tenant is an entity other than a corporation whose stock is publicly traded, permit the transfer of an ownership interest in Tenant so as to result in a change in the current control of Tenant, (4) sublet any portion of the Premises, (5) grant any license, concession, or other right of occupancy of any portion of the Premises, or (6) permit the use of the Premises by any parties other than Tenant (any of the events listed in Section 10(a)(1) through 10(a)(6) being a "Transfer").

(b) Consent Standards. Landlord shall not unreasonably withhold its consent to any assignment or subletting of the Premises, provided that the proposed transferee (1) is creditworthy, (2) has a good reputation in the business community, (3) will use the Premises for the Permitted Use (thus, excluding, without limitation, uses for credit processing and telemarketing) and will not use the Premises in any manner that would conflict with any exclusive use agreement or other similar agreement entered into by Landlord with any other tenant of the Building or Complex, (4) will not use the Premises, Building or Project in a manner that would materially increase the pedestrian or vehicular traffic to the Premises, Building or Project, (5) is not a governmental entity, or subdivision or agency thereof, (6) is not another occupant of the Building or Complex, and (7) is not a person or entity with whom Landlord is then, or has been within the six-month period prior to the time Tenant seeks to enter into such assignment or subletting, negotiating to lease space in the Building or Complex or any Affiliate of any such person or entity; otherwise, Landlord may withhold its consent in its sole discretion. Additionally, Landlord may withhold its consent in its sole discretion to any proposed Transfer if any Event of Default by Tenant then exists.

(c) Request for Consent. If Tenant requests Landlord's consent to a Transfer, then, at least 15 business days prior to the effective date of the proposed Transfer, Tenant shall provide Landlord with a written description of all terms and conditions of the proposed Transfer, copies of the proposed documentation, and the following information about the proposed transferee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises, banking, financial, and other credit information; and general

references sufficient to enable Landlord to determine the proposed transferee's creditworthiness and character. Concurrently with Tenant's notice of any request for consent to a Transfer, Tenant shall pay to Landlord a fee of $1,000 to defray Landlord's expenses in reviewing such request, and Tenant shall also reimburse Landlord immediately upon request for its reasonable attorneys' fees incurred in connection with considering any request for consent to a Transfer.

(d) Conditions to Consent. If Landlord consents to a proposed Transfer, then the proposed transferee shall deliver to Landlord a written agreement whereby it expressly assumes Tenant's obligations hereunder, however, any transferee of less than all of the space in the Premises shall be liable only for obligations under this Lease that are properly allocable to the space subject to the Transfer for the period of the Transfer. No Transfer shall release Tenant from its obligations under this Lease, but rather Tenant and its transferee shall be jointly and severally liable therefor. Landlord's consent to any Transfer shall not waive Landlord's rights as to any subsequent Transfers. If an Event of Default occurs while the Premises or any part thereof are subject to a Transfer, then Landlord, in addition to its other remedies, may collect directly from such transferee all rents becoming due to Tenant and apply such rents against Rent. Tenant authorizes its transferees to make payments of rent directly to Landlord upon receipt of notice from Landlord to do so following the occurrence of an Event of Default hereunder. Tenant shall pay for the cost of any demising walls or other improvements necessitated by a proposed subletting or assignment.

(e) Attornment by Subtenants. Each sublease by Tenant hereunder shall be subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord under this Lease, Landlord may, at its option, take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord's option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not be (1) liable for any previous act or omission of Tenant under such sublease, (2) subject to any counterclaim, offset or defense that such subtenant might have against Tenant, (3) bound by any previous modification of such sublease not approved by Landlord in writing or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent shall remain due and owing, notwithstanding such advance payment, (4) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look solely to Tenant for refund or reimbursement, or (5) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any instruments Landlord may reasonably request to evidence and confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have agreed to be bound by the terms and conditions set forth in this Section 10(e). The provisions of this Section 10(e) shall be self-operative, and no further instrument shall be required to give effect to this provision.

(f) Cancellation. Landlord may, within 30 days after submission of Tenant's written request for Landlord's consent to an assignment or subletting, cancel this Lease as to the portion of the Premises proposed to be sublet or assigned as of the date the proposed Transfer is to be effective. If Landlord cancels this Lease as to any portion of the Premises, then this Lease shall cease for such portion of the Premises and Tenant shall pay to Landlord all Rent accrued through the cancellation date relating to the portion of the Premises covered by the proposed Transfer. Thereafter, Landlord may lease such portion of the Premises to the prospective transferee (or to any other person) without liability to Tenant.

(g) Additional Compensation. Tenant shall pay to Landlord, immediately upon receipt thereof, the excess of (1) all compensation received by Tenant for a Transfer less the actual

out-of-pocket costs reasonably incurred by Tenant with unaffiliated third parties (i.e., brokerage commissions and tenant finish work) in connection with such Transfer (such costs shall be amortized on a straight-line basis over the term of the Transfer in question) over (2) the Rent allocable to the portion of the Premises covered thereby.

(h) Permitted Transfers. Notwithstanding Section 10(a), Tenant may Transfer all or part of its interest in this Lease or all or part of the Premises (a "Permitted Transfer") to the following types of entities (a "Permitted Transferee") without the written consent of Landlord:

(1) an Affiliate of Tenant;

(2) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or with which Tenant, or its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions governing merger and consolidation of business entities, so long as (A) Tenant's obligations hereunder are assumed by the entity surviving such merger or created by such consolidation; and (B) the Tangible Net Worth of the surviving or created entity is not less than the Tangible Net Worth of Tenant as of the date hereof; or

(3) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all or substantially all of Tenant's assets if such entity's Tangible Net Worth after such acquisition is not less than the Tangible Net Worth of Tenant as of the date hereof.

Tenant shall promptly notify Landlord of any such Permitted Transfer. Tenant shall remain liable for the performance of all of the obligations of Tenant hereunder, or if Tenant no longer exists because of a merger, consolidation, or acquisition, the surviving or acquiring entity shall expressly assume in writing the obligations of Tenant hereunder. Additionally, the Permitted Transferee shall comply with all of the terms and conditions of this Lease, including the Permitted Use, and the use of the Premises by the Permitted Transferee may not violate any other agreements affecting the Premises, the Building or the Complex, Landlord or other tenants of the Building or the Complex. No later than 30 days after the effective date of any Permitted Transfer, Tenant agrees to furnish Landlord with (A) copies of the instrument effecting any of the foregoing Transfers, (B) documentation establishing Tenant's satisfaction of the requirements set forth above applicable to any such Transfer, and (C) evidence of insurance as required under this Lease with respect to the Permitted Transferee. The occurrence of a Permitted Transfer shall not waive Landlord's rights as to any subsequent Transfers. "Tangible Net Worth" means the excess of total assets over total liabilities, in each case as determined in accordance with generally accepted accounting principles consistently applied ("GAAP"), excluding, however, from the determination of total assets all assets which would be classified as intangible assets under GAAP including goodwill, licenses, patents, trademarks, trade names, copyrights, and franchises. Any subsequent Transfer by a Permitted Transferee shall be subject to the terms of this Section 10.

(i) Assignment of Subrents. Tenant hereby irrevocably assigns to Landlord all rents due or to become due from any assignee or transferee of or sublessee under this Lease or any tenant or occupant of the Premises or any part thereof, and authorizes and empowers Landlord in the name of Tenant or otherwise, to collect and receive the same, provided that, so long as Tenant is not in default under this Lease beyond the expiration of the applicable cure periods, if any, provided herein, Tenant shall have the right to collect and receive such rents for its own uses and purposes. Upon any default by Tenant under this Lease, Landlord shall have absolute title to such rents and the absolute right to collect and receive the same. Landlord shall apply to the Rent due under this Lease the net amount (after deducting all costs and expenses of collection, including, without limitation, attorneys' fees and expenses) of any rents so collected and received by it.

11. Insurance; Waivers; Subrogation; Indemnity.

(a) Tenant's Insurance. Effective as of the earlier of (1) the date Tenant enters or occupies the Premises, or (2) the Commencement Date, and continuing throughout the Term, Tenant shall maintain the following insurance policies: (A) commercial general liability insurance in amounts of $2,000,000 per occurrence or, following the expiration of the initial Term, such other amounts as Landlord may from time to time reasonably require (and, if the use and occupancy of the Premises include any activity or matter that is or may be excluded from coverage under a commercial general liability policy [e.g., the sale, service or consumption of alcoholic beverages], Tenant shall obtain such endorsements to the commercial general liability policy or otherwise obtain insurance to insure all liability arising from such activity or matter [including liquor liability, if applicable] in such amounts as Landlord may reasonably require), insuring Tenant, Landlord, Landlord's property management company and Landlord's asset management company against all liability for injury to or death of a person or persons or damage to property arising from the use and occupancy of the Premises and (without implying any consent by Landlord to the installation thereof) the installation, operation, maintenance, repair or removal of Tenant's Off-Premises Equipment, (B) insurance covering the full value of all alterations and improvements and betterments in the Premises, naming Landlord and Landlord's Mortgagee as additional loss payees as their interests may appear, (C) insurance covering the full value of all furniture, trade fixtures and personal property (including property of Tenant or others) in the Premises or otherwise placed in the Project by or on behalf of a Tenant Party (including Tenant's Off-Premises Equipment), (D) contractual liability insurance sufficient to cover Tenant's indemnity obligations hereunder (but only if such contractual liability insurance is not already included in Tenant's commercial general liability insurance policy), (E) worker's compensation insurance, and (F) business interruption insurance. Tenant's insurance shall provide primary coverage to Landlord when any policy issued to Landlord provides duplicate or similar coverage, and in such circumstance Landlord's policy will be excess over Tenant's policy. Tenant shall furnish to Landlord certificates of such insurance and such other evidence satisfactory to Landlord of the maintenance of all insurance coverages required hereunder at least ten days prior to the earlier of the Commencement Date or the date Tenant enters or occupies the Premises, and at least 15 days prior to each renewal of said insurance, and Tenant shall obtain a written obligation on the part of each insurance company to notify Landlord at least 30 days before cancellation or a material change of any such insurance policies. All such insurance policies shall be in form, and issued by companies with an A.M. Best rating of A or better, reasonably satisfactory to Landlord. If Tenant fails to comply with the foregoing insurance requirements or to deliver to Landlord the certificates or evidence of coverage required herein, Landlord, in addition to any other remedy available pursuant to this Lease or otherwise, may, but shall not be obligated to, obtain such insurance and Tenant shall pay to Landlord on demand the premium costs thereof, plus an administrative fee of 15% of such cost.

(b) Landlord's Insurance. Throughout the Term of this Lease, Landlord shall maintain, as a minimum, the following insurance policies: (1) property insurance for the Building's replacement value (excluding property required to be insured by Tenant), less a commercially-reasonable deductible if Landlord so chooses, and (2) commercial general liability insurance in an amount of not less than $3,000,000. Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it may deem necessary. The cost of all insurance carried by Landlord with respect to the Project shall be included in Operating Costs. The foregoing insurance policies and any other insurance carried by Landlord shall be for the sole benefit of Landlord and under Landlord's sole control, and Tenant shall have no right or claim to any proceeds thereof or any other rights thereunder.

(c) No Subrogation. Landlord and Tenant each waives any claim it might have against the other for any damage to or theft, destruction, loss, or loss of use of any property, to the extent the

same is insured against under any insurance policy of the types described in this Section 11 that covers the Project, the Premises, Landlord's or Tenant's fixtures, personal property, leasehold improvements, or business, or is required to be insured against under the terms hereof, regardless of whether the negligence of the other party caused such Loss (defined below). Additionally, Tenant waives any claim it may have against Landlord for any Loss to the extent such Loss is caused by a terrorist act. Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier's rights of recovery under subrogation or otherwise against the other party.

(d) Indemnity. Subject to Section 11(c), Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages, and expenses (including reasonable attorneys' fees) arising from any injury to or death of any person or the damage to or theft, destruction, loss, or loss of use of any property or inconvenience (a "Loss"), occurring on the Premises or arising out of the installation, operation, maintenance, repair or removal of any of Tenant's Off-Premises Equipment, except to the extent that such Loss is caused by the negligence of Landlord. Subject to Section 11(c), Landlord shall defend, indemnify, and hold harmless Tenant and its agents from and against all claims, demands, liabilities, causes of action, suits, judgments, and expenses (including reasonable attorneys' fees) for any Loss arising from any occurrence in the Building's common areas, except to the extent that such Loss is caused by the negligence of Tenant. The indemnities set forth in this Lease shall survive termination or expiration of this Lease for a period of six (6) months after its termination, and shall not terminate or be waived, diminished or affected in any manner by any abatement or apportionment of Rent under any provision of this Lease. If any proceeding is filed for which indemnity is required hereunder, the indemnifying party agrees, upon request therefor, to defend the indemnified party in such proceeding at its sole cost utilizing counsel satisfactory to the indemnified party.

12. Subordination; Attornment; Notice to Landlord's Mortgagee.

(a) Subordination. This Lease shall be subordinate to any deed of trust, mortgage, or other security instrument (each, a "Mortgage"), or any ground lease, master lease, or primary lease (each, a "Primary Lease"), that now or hereafter covers all or any part of the Premises (the mortgagee under any such Mortgage, beneficiary under any such deed of trust, or the lessor under any such Primary Lease is referred to herein as a "Landlord's Mortgagee"). Any Landlord's Mortgagee may elect, at any time, unilaterally, to make this Lease superior to its Mortgage, Primary Lease, or other interest in the Premises by so notifying Tenant in writing. The provisions of this Section shall be self-operative and no further instrument of subordination shall be required; however, in confirmation of such subordination, Tenant shall execute and return to Landlord (or such other party designated by Landlord) within ten days after written request therefor such documentation, in recordable form if required, as a Landlord's Mortgagee may reasonably request to evidence the subordination of this Lease to such Landlord's Mortgagee's Mortgage or Primary Lease (including a subordination, non-disturbance and attornment agreement) or, if the Landlord's Mortgagee so elects, the subordination of such Landlord's Mortgagee's Mortgage or Primary Lease to this Lease.

(b) Attornment. Tenant shall attorn to any party succeeding to Landlord's interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon such party's request, and shall execute such agreements confirming such attornment as such party may reasonably request.

(c) Notice to Landlord's Mortgagee. Tenant shall not seek to enforce any remedy it may have for any default on the part of Landlord without first giving written notice by certified mail, return receipt requested, specifying the default in reasonable detail, to any Landlord's Mortgagee whose address has been given to Tenant, and affording such Landlord's Mortgagee a reasonable opportunity to perform Landlord's obligations hereunder.

(d) Landlord's Mortgagee's Protection Provisions. If Landlord's Mortgagee shall succeed to the interest of Landlord under this Lease, Landlord's Mortgagee shall not be: (1) liable for any act or omission of any prior lessor (including Landlord); (2) bound by any rent or additional rent or advance rent which Tenant might have paid for more than the current month to any prior lessor (including Landlord), and all such rent shall remain due and owing, notwithstanding such advance payment; (3) bound by any security or advance rental deposit made by Tenant which is not delivered or paid over to Landlord's Mortgagee and with respect to which Tenant shall look solely to Landlord for refund or reimbursement; (4) bound by any termination, amendment or modification of this Lease made without Landlord's Mortgagee's consent and written approval, except for those terminations, amendments and modifications permitted to be made by Landlord without Landlord's Mortgagee's consent pursuant to the terms of the loan documents between Landlord and Landlord's Mortgagee; (5) subject to the defenses which Tenant might have against any prior lessor (including Landlord); and (6) subject to the offsets which Tenant might have against any prior lessor (including Landlord) except for those offset rights which (A) are expressly provided in this Lease, (B) relate to periods of time following the acquisition of the Building by Landlord's Mortgagee, and (C) Tenant has provided written notice to Landlord's Mortgagee and provided Landlord's Mortgagee a reasonable opportunity to cure the event giving rise to such offset event. Landlord's Mortgagee shall have no liability or responsibility under or pursuant to the terms of this Lease or otherwise after it ceases to own an interest in the Project. Nothing in this Lease shall be construed to require Landlord's Mortgagee to see to the application of the proceeds of any loan, and Tenant's agreements set forth herein shall not be impaired on account of any modification of the documents evidencing and securing any loan.

13. Rules and Regulations. Tenant shall comply with the rules and regulations of the Project which are attached hereto as Exhibit C. Landlord may, from time to time, change such rules and regulations for the safety, care, or cleanliness of the Project and related facilities, provided that such changes are applicable to all tenants of the Project, will not unreasonably interfere with Tenant's use of the Premises and are enforced by Landlord in a non- discriminatory manner. Tenant shall be responsible for the compliance with such rules and regulations by each Tenant Party.

14. Condemnation.

(a) Total Taking. If the entire Building or Premises are taken by right of eminent domain or conveyed in lieu thereof (a "Taking"), this Lease shall terminate as of the date of the Taking.

(b) Partial Taking—Tenant's Rights. If any part of the Building becomes subject to a Taking and such Taking will prevent Tenant from conducting on a permanent basis its business in the Premises in a manner reasonably comparable to that conducted immediately before such Taking, then Tenant may terminate this Lease as of the date of such Taking by giving written notice to Landlord within 30 days after the Taking, and Basic Rent and Additional Rent shall be apportioned as of the date of such Taking. If Tenant does not terminate this Lease, then Rent shall be abated on a reasonable basis as to that portion of the Premises rendered untenantable by the Taking.

(c) Partial Taking—Landlord's Rights. If any material portion, but less than all, of the Building becomes subject to a Taking, or if Landlord is required to pay any of the proceeds arising from a Taking to a Landlord's Mortgagee, then Landlord may terminate this Lease by delivering written notice thereof to Tenant within 30 days after such Taking, and Basic Rent and Additional

Rent shall be apportioned as of the date of such Taking. If Landlord does not so terminate this Lease, then this Lease will continue, but if any portion of the Premises has been taken, Rent shall ▇▇▇▇▇ as provided in the last sentence of Section 14(b).

(d) Temporary Taking. If all or any portion of the Premises becomes subject to a Taking for a limited period of time, this Lease shall remain in full force and effect and Tenant shall continue to perform all of the terms, conditions and covenants of this Lease, including the payment of Basic Rent and all other amounts required hereunder. Tenant shall be entitled to receive the entire award made in connection with any other temporary condemnation or other taking attributable to any period within the Term. Landlord shall be entitled to the entire award for any such temporary condemnation or other taking which relates to a period after the expiration of the Term or which is allocable to the cost of restoration of the Premises. If any such temporary condemnation or other taking terminates prior to the expiration of the Term, Tenant shall restore the Premises as nearly as possible to the condition prior to the condemnation or other taking, at Tenant's sole cost and expense; provided that, Tenant shall receive the portion of the award attributable to such restoration.

(e) Award. If any Taking occurs, then Landlord shall receive the entire award or other compensation for the Land, the Building, and other improvements taken; however, Tenant may separately pursue a claim (to the extent it will not reduce Landlord's award) against the condemnor for the value of Tenant's personal property which Tenant is entitled to remove under this Lease, moving costs, loss of business, and other claims it may have.

15. Fire or Other Casualty.

(a) Repair Estimate. If the Premises or the Building are damaged by fire or other casualty (a "Casualty"), Landlord shall, within 60 days after such Casualty, deliver to Tenant a good faith estimate (the "Damage Notice") of the time needed to repair the damage caused by such Casualty.

(b) Tenant's Rights. If a material portion of the Premises is damaged by Casualty such that Tenant is prevented from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Casualty and Landlord estimates that the damage caused thereby cannot be repaired within 270 days after the date of the Casualty (the "Repair Period"), then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant. If Landlord undertakes to repair the Premises and does not do so within the Repair Period, and provided that such delay is not caused by Tenant, then Tenant shall have the option to terminate this Lease on the day following the Repair Period if the Premises are not, on said date, in a condition that is substantially similar to the condition the Premises were in prior to the Casualty.

(c) Landlord's Rights. If a Casualty damages the Premises or a material portion of the Building and (1) Landlord estimates that the damage to the Premises cannot be repaired within the Repair Period, (2) the damage to the Premises exceeds 50% of the replacement cost thereof (excluding foundations and footings), as estimated by Landlord, and such damage occurs during the last two years of the Term, (3) regardless of the extent of damage to the Premises, the damage is not fully covered by Landlord's insurance policies or Landlord makes a good faith determination that restoring the Building would be uneconomical, or (4) Landlord is required to pay any insurance proceeds arising out of the Casualty to a Landlord's Mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant.

(d) Repair Obligation. If neither party elects to terminate this Lease following a Casualty, then Landlord shall, within a reasonable time after such Casualty, begin to repair the Premises and shall proceed with reasonable diligence to restore the Premises to substantially the same condition

as they existed immediately before such Casualty; however, Landlord shall not be required to repair or replace any alterations or betterments within the Premises that were installed by Tenant and were not a part of Tenant's Rent (which, if Tenant desires to rebuild such alterations or betterments, shall be promptly and with due diligence repaired and restored by Tenant at Tenant's sole cost and expense) or any furniture, equipment, trade fixtures or personal property of Tenant or others in the Premises or the Building, and Landlord's obligation to repair or restore the Premises shall be limited to the extent of the insurance proceeds actually received by Landlord for the Casualty in question. If this Lease is terminated under the provisions of this Section 15, Landlord shall be entitled to the full proceeds of the insurance policies providing coverage for all alterations, improvements and betterments in the Premises (and, if Tenant has failed to maintain insurance on such items as required by this Lease, Tenant shall pay Landlord an amount equal to the proceeds Landlord would have received had Tenant maintained insurance on such items as required by this Lease).

(e) Abatement of Rent. If the Premises are damaged by Casualty, Rent for the portion of the Premises rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the completion of Landlord's repairs (or until the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be), unless a Tenant Party caused such damage, in which case, Tenant shall continue to pay Rent without abatement.

16. Personal Property Taxes. Tenant shall be liable for all taxes levied or assessed against personal property, furniture, or fixtures placed by Tenant in the Premises or in or on the Building or Project. If any taxes for which Tenant is liable are levied or assessed against Landlord or Landlord's property and Landlord elects to pay the same, or if the assessed value of Landlord's property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, then Tenant shall pay to Landlord, within 30 days following written request therefor, the part of such taxes for which Tenant is primarily liable hereunder; however, Landlord shall not pay such amount if Tenant notifies Landlord that it will contest the validity or amount of such taxes before Landlord makes such payment, and thereafter diligently proceeds with such contest in accordance with Law and if the non-payment thereof does not pose a threat of loss or seizure of the Project or interest of Landlord therein or impose any fee or penalty against Landlord.

17. Events of Default. Each of the following occurrences shall be an "Event of Default":

(a) Payment Default. Tenant's failure to pay Rent within five days after Landlord has delivered written notice to Tenant that the same is due; however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice if Tenant fails to pay Rent when due and, during the 12 month interval preceding such failure, Landlord has given Tenant written notice of failure to pay Rent on one or more occasions;

(b) Abandonment. Tenant (1) abandons or vacates the Premises or any substantial portion thereof or (2) fails to continuously operate its business in the Premises;

(c) Estoppel. Tenant fails to provide any estoppel certificate after Landlord's written request therefor pursuant to Section 25(e) and such failure shall continue for five days after Landlord's second written notice thereof to Tenant;

(d) Insurance. Tenant fails to procure, maintain and deliver to Landlord evidence of the insurance policies and coverages as required under Section 11(a);

(e) Mechanic's Liens. Tenant fails to pay and release of record, or diligently contest and bond around, any mechanic's lien filed against the Premises or the Project for any work performed, materials furnished, or obligation incurred by or at the request of Tenant, within the time and in the manner required by Section 8(d);

(f) Other Defaults. Tenant's failure to perform, comply with, or observe any other agreement or obligation of Tenant under this Lease and the continuance of such failure for a period of more than 30 days after Landlord has delivered to Tenant written notice thereof; and

(g) Insolvency. The filing of a petition by or against Tenant (the term "Tenant" shall include, for the purpose of this Section 17(g), any guarantor of Tenant's obligations hereunder) (1) in any bankruptcy or other insolvency proceeding; (2) seeking any relief under any state or federal debtor relief law; (3) for the appointment of a liquidator or receiver for all or substantially all of Tenant's property or for Tenant's interest in this Lease; (4) for the reorganization or modification of Tenant's capital structure; or (5) in any assignment for the benefit of creditors proceeding; however, if such a petition is filed against Tenant, then such filing shall not be an Event of Default unless Tenant fails to have the proceedings initiated by such petition dismissed within 90 days after the filing thereof.

18. Remedies. Upon any Event of Default, Landlord may, at its election and in addition to all other remedies available at law or in equity, terminate this Lease through the delivery of written notice to that effect to Tenant or terminate Tenant's right to possession only, without terminating this Lease. In the event Landlord elects to terminate this Lease pursuant to this Section 18, the Term shall expire and terminate as of the later of the fifth day after Landlord delivers such notice of termination or the termination date stated in the notice with the same force and effect as though such termination date were the date originally set forth in this Lease as the expiration date of the Term.

(a) Re-Entry Without Termination. Upon any termination of Tenant's right to possession of the Premises without termination of this Lease, Landlord may, at Landlord's option, enter into the Premises pursuant to applicable law, remove all signs and other evidence of Tenant's tenancy, remove all property from the Premises and store such property in a public warehouse or elsewhere, at the cost of, and for the account of Tenant, and take and hold possession of the Premises without: (1) being deemed guilty of trespass; (2) becoming liable for any loss or damage which may be occasioned by such entry and/or possession; (3) such entry and/or possession terminating this Lease; and (4) releasing Tenant, in whole or in part, from any obligation, including Tenant's obligation to pay Rent for the full Term. Landlord may, but need not, relet the Premises or any part thereof for such rent and upon such terms as Landlord, in its sole discretion, shall determine (including the right to relet the Premises as part of a larger area, the right to change the character or the use made of the Premises, and the right to lease all or any portion of the Premises for a term extending beyond the Term of this Lease), and Landlord shall not be required to accept any tenant offered by Tenant or to observe any instructions given by Tenant about such reletting. In any such case, Landlord may make repairs, alterations and additions in or to the Premises, and redecorate the same to the extent Landlord deems necessary or desirable, in its sole discretion. All rentals and other sums received by Landlord from any such reletting shall be applied as follows: first, to the payment of any indebtedness other than Rent due hereunder from Tenant to Landlord; second, to the payment of any costs and expenses of such alterations and repairs; third, to the payment of Landlord's expenses of reletting, including, without limitation, broker's commissions, attorneys' fees and lease inducements, such as moving or leasehold improvement allowances; fourth, to the payment of Rent; and the residue, if any, shall be held by Landlord and applied in payment of future Rent as the same may become due and payable hereunder. If such rentals and other sums received from such reletting during any month be less than the Rent to be paid during said month by Tenant hereunder, Tenant shall pay such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. Notwithstanding any such re-entry and possession by Landlord, Landlord may at any time hereafter elect to terminate this Lease for such previous breach.

(b) Damages in the Event of Termination. Tenant acknowledges that the damages Landlord would incur in connection with terminating this Lease following a default by Tenant would be

difficult to estimate or ascertain. In the event Landlord elects to terminate this Lease, Landlord may, in addition to other remedies available at law or in equity, recover from Tenant, as liquidated damages, an amount equal to the sum of the following: (1) all unpaid Rent that is payable by Tenant hereunder and that accrues as of the effective date of termination; plus (2) a sum of money equal to the entire amount of Rent that would be payable under the Lease for the lesser of the following two periods, which amount shall be immediately due and payable upon demand but which shall be discounted to present value using a discount rate equal to the discount rate of the Federal Reserve Bank of Minneapolis as of the date of termination plus one percent (1%): (A) the one year period commencing upon the effective date of termination, or (B) the period commencing upon the effective date of termination and ending upon the original date of the expiration of the Term. For purposes of calculating the amount of Rent that would be payable under this Lease for the period succeeding the effective date of termination, such Rent shall be computed on the basis of the average monthly amount of Rent accruing during the 24 month period immediately preceding the default to which such termination relates (exclusive of any months in which Tenant received "free" or abated rent concessions); provided, however, if the default occurs prior to the expiration of the first 24 months of this Lease, then the Rent shall be computed on the basis of the average monthly amount of Rent accruing during all months preceding the month in which said default occurred (exclusive of any months in which Tenant received "free" or abated rent concessions). Landlord's failure to relet the Premises shall not affect Tenant's liability. The terms "enter," "entry," "re-enter," and "re-entry" are not limited to their technical meanings.

(c) Miscellaneous. Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the remedies herein provided or any other remedies available at law or in equity, nor shall pursuit of any remedy herein provided constitute a forfeiture or waiver of any Rent due to Landlord hereunder or of any damages accruing to the non-breaching party by reason of the violation of any term, provision and/or covenant herein contained. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event Tenant is evicted or dispossessed for any cause, or in the event Landlord obtains possession of the Premises by reason of Tenant's violation of any term of this Lease.

19. Payment by Tenant; Non-Waiver; Cumulative Remedies.

(a) Payment by Tenant. Upon any Event of Default, Tenant shall pay to Landlord all costs incurred by Landlord (including court costs and reasonable attorneys' fees and expenses) in (1) obtaining possession of the Premises, (2) removing and storing Tenant's or any other occupant's property, (3) repairing, restoring, altering, remodeling, or otherwise putting the Premises into condition acceptable to a new tenant, (4) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part of the Premises (including brokerage commissions, cost of tenant finish work, and other costs incidental to such reletting), (5) performing Tenant's obligations which Tenant failed to perform, and (6) enforcing, or advising Landlord of, its rights, remedies, and recourses arising out of the default. To the full extent permitted by law, Landlord and Tenant agree the federal and state courts of the state in which the Premises are located shall have exclusive jurisdiction over any matter relating to or arising from this Lease and the parties' rights and obligations under this Lease.

(b) No Waiver. Landlord's acceptance of Rent following an Event of Default shall not waive Landlord's rights regarding such Event of Default. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord's rights regarding any future violation of such term. Landlord's acceptance of any partial payment of Rent shall not waive Landlord's rights with regard to the remaining portion of the Rent that is due, regardless of any endorsement or other statement on any instrument delivered in payment of Rent or any writing

delivered in connection therewith; accordingly, Landlord's acceptance of a partial payment of Rent shall not constitute an accord and satisfaction of the full amount of the Rent that is due.

(c) Cumulative Remedies. Any and all remedies set forth in this Lease: (1) shall be in addition to any and all other remedies Landlord may have at law or in equity, (2) shall be cumulative, and (3) may be pursued successively or concurrently as Landlord may elect. The exercise of any remedy by Landlord shall not be deemed an election of remedies or preclude Landlord from exercising any other remedies in the future. Additionally, Tenant shall defend, indemnify and hold harmless Landlord, Landlord's Mortgagee and their respective representatives and agents from and against all claims, demands, liabilities, causes of action, suits, judgments, damages and expenses (including reasonable attorneys' fees) arising from Tenant's failure to perform its obligations under this Lease.

20. Intentionally Omitted.

21. Surrender of Premises. No act by Landlord shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless it is in writing and signed by Landlord. At the expiration or termination of this Lease, Tenant shall deliver to Landlord the Premises with all improvements located therein in good repair and condition, free of Hazardous Materials placed on the Premises during the Term, broom-clean, reasonable wear and tear (and condemnation and Casualty damage not caused by Tenant, as to which Sections 14 and 15 shall control) excepted, and shall deliver to Landlord all keys to the Premises. Provided that Tenant has performed all of its obligations hereunder, Tenant may remove all unattached trade fixtures, furniture, and personal property placed in the Premises or elsewhere in the Building by Tenant (but Tenant may not remove any such item which was paid for, in whole or in part, by Landlord or any wiring or cabling unless Landlord requires such removal). Additionally, at Landlord's option, Tenant shall remove such alterations, additions, improvements, trade fixtures, personal property, equipment, wiring, conduits, cabling, and furniture (including Tenant's Off-Premises Equipment) as Landlord may request; however, Tenant shall not be required to remove any addition or improvement to the Premises or the Project if Landlord has specifically agreed in writing that the improvement or addition in question need not be removed. Tenant shall repair all damage caused by such removal. All items not so removed shall, at Landlord's option, be deemed to have been abandoned by Tenant and may be appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant and without any obligation to account for such items. The provisions of this Section 21 shall survive the end of the Term.

22. Holding Over. If Tenant fails to vacate the Premises at the end of the Term, then Tenant shall be, at Landlord's option without Tenant's execution of any document or receipt of any notice, a tenant at sufferance and, in addition to all other damages and remedies to which Landlord may be entitled for such holding over, (a) Tenant shall pay, in addition to the other Rent, Basic Rent equal to the greater of (1) 150% of the Rent payable during the last month of the Term, or (2) 125% of the prevailing rental rate in the Building for similar space, and (b) Tenant shall otherwise continue to be subject to all of Tenant's obligations under this Lease. The provisions of this Section 22 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys' fees) and liability resulting from such failure, including any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom.

23. Certain Rights Reserved by Landlord. Provided that the exercise of such rights does not unreasonably interfere with Tenant's occupancy of the Premises, Landlord shall have the following rights:

(a) Building Operations. To decorate and to make inspections, repairs, alterations, additions, changes, or improvements, whether structural or otherwise, in and about the Project, or any part thereof; to enter upon the Premises (after giving Tenant reasonable notice thereof, which may be oral notice, except in cases of real or apparent emergency, in which case no notice shall be required) and, during the continuance of any such work, to temporarily close doors, entryways, public space, and corridors in the Building; to interrupt or temporarily suspend Building services and facilities; to change the name of the Building; and to change the arrangement and location of entrances or passageways, doors, and doorways, corridors, elevators, stairs, restrooms, or other public parts of the Building;

(b) Security. To take such reasonable measures as Landlord deems advisable for the security of the Building and its occupants; evacuating the Building for cause, suspected cause, or for drill purposes; temporarily denying access to the Building; and closing the Building after normal business hours and on Sundays and holidays, subject, however, to Tenant's right to enter when the Building is closed after normal business hours under such reasonable regulations as Landlord may prescribe from time to time;

(c) Prospective Purchasers and Lenders. To enter the Premises at all reasonable hours to show the Premises to prospective purchasers or lenders; and

(d) Prospective Tenants. At any time during the last 12 months of the Term (or earlier if Tenant has notified Landlord in writing that it does not desire to renew the Term) or at any time following the occurrence of an Event of Default, to enter the Premises at all reasonable hours to show the Premises to prospective tenants.

24. Substitution Space. Landlord may, at Landlord's expense, relocate Tenant within the Building to space which is comparable in size, utility and condition to the Premises. If Landlord relocates Tenant, Landlord shall reimburse Tenant for Tenant's reasonable out-of-pocket expenses for moving Tenant's furniture, equipment, and supplies from the Premises to the relocation space and for reprinting Tenant's stationery of the same quality and quantity as Tenant's stationery supply on hand immediately before Landlord's notice to Tenant of the exercise of this relocation right. Upon such relocation, the relocation space shall be deemed to be the Premises and the terms of the Lease shall remain in full force and shall apply to the relocation space. No amendment or other instrument shall be necessary to effectuate the relocation contemplated by this Section; however, if requested by Landlord, Tenant shall execute an appropriate amendment document within ten business days after Landlord's written request therefor. If Tenant fails to execute such relocation amendment within such time period, or if Tenant fails to relocate within the time period stated in Landlord's relocation notice to Tenant (or, if such relocation space is not available on the date specified in Landlord's relocation notice, as soon thereafter as the relocation space becomes available and is tendered to Tenant in the condition required by this Lease), then, in addition to Landlord's other remedies set forth in this Lease, at law and/or in equity, Landlord may terminate this Lease by notifying Tenant in writing thereof at least 60 days prior to the termination date contained in Landlord's termination notice. Time is of the essence with respect to Tenant's obligations under this Section.

25. Miscellaneous.

(a) Landlord Transfer. Landlord may transfer any portion of the Project and any of its rights under this Lease. If Landlord assigns its rights under this Lease, then Landlord shall thereby be released from any further obligations hereunder arising after the date of transfer, provided that the

assignee assumes in writing Landlord's obligations hereunder arising from and after the transfer date.

(b) Landlord's Liability. The liability of Landlord (and its partners, shareholders or members) to Tenant (or any person or entity claiming by, through or under Tenant) for any default by Landlord under the terms of this Lease or any matter relating to or arising out of the occupancy or use of the Premises and/or other areas of the Building shall be limited to Tenant's actual direct, but not consequential, damages therefor and shall be recoverable only from the interest of Landlord in the Building, and Landlord (and its partners, shareholders or members) shall not be personally liable for any deficiency.

(c) Force Majeure. Other than for Tenant's obligations under this Lease that can be performed by the payment of money (e.g., payment of Rent and maintenance of insurance), whenever a period of time is herein prescribed for action to be taken by either party hereto, such party shall not be liable or responsible for, and there shall be excluded from the computation of any such period of time, any delays due to strikes, riots, acts of God, shortages of labor or materials, war, terrorist acts or activities, governmental laws, regulations, or restrictions, or any other causes of any kind whatsoever which are beyond the control of such party.

(d) Brokerage. Neither Landlord nor Tenant has dealt with any broker or agent in connection with the negotiation or execution of this Lease, other than Colliers ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ and Northstar Partners, whose commissions shall be paid by Landlord pursuant to a separate written agreement. Tenant and Landlord shall each indemnify the other against all costs, expenses, attorneys' fees, liens and other liability for commissions or other compensation claimed by any broker or agent claiming the same by, through, or under the indemnifying party.

(e) Estoppel Certificates. From time to time, Tenant shall furnish to any party designated by Landlord, within ten days after Landlord has made a request therefor, a certificate signed by Tenant confirming and containing such factual certifications and representations as to this Lease as Landlord may reasonably request. Unless otherwise required by Landlord's Mortgagee or a prospective purchaser or mortgagee of the Project, the initial form of estoppel certificate to be signed by Tenant is attached hereto as Exhibit F. If Tenant does not deliver to Landlord the certificate signed by Tenant within such required time period, Landlord, Landlord's Mortgagee and any prospective purchaser or mortgagee, may conclusively presume and rely upon the following facts: (1) this Lease is in full force and effect, (2) the terms and provisions of this Lease have not been changed except as otherwise represented by Landlord, (3) not more than one monthly installment of Basic Rent and other charges have been paid in advance, (4) there are no claims against Landlord nor any defenses or rights of offset against collection of Rent or other charges, and (5) Landlord is not in default under this Lease. In such event, Tenant shall be estopped from denying the truth of the presumed facts.

(f) Notices. All notices and other communications given pursuant to this Lease shall be in writing and shall be (1) mailed by first class, United States Mail, postage prepaid, certified, with return receipt requested, and addressed to the parties hereto at the address specified in the Basic Lease Information, (2) hand delivered to the intended addressee, (3) sent by a nationally recognized overnight courier service, or (4) sent by facsimile transmission during normal business hours followed by a confirmatory letter sent in another manner permitted hereunder. All notices shall be effective upon delivery to the address of the addressee. The parties hereto may change their addresses by giving notice thereof to the other in conformity with this provision.

(g) Separability. If any clause or provision of this Lease is illegal, invalid, or unenforceable under present or future laws, then the remainder of this Lease shall not be affected thereby and in lieu of such clause or provision, there shall be added as a part of this Lease a clause or provision

as similar in terms to such illegal, invalid, or unenforceable clause or provision as may be possible and be legal, valid, and enforceable.

(h) Amendments; Binding Effect; No Electronic Records. This Lease may not be amended except by instrument in writing signed by Landlord and Tenant. No provision of this Lease shall be deemed to have been waived by Landlord unless such waiver is in writing signed by Landlord, and no custom or practice which may evolve between the parties in the administration of the terms hereof shall waive or diminish the right of Landlord to insist upon the performance by Tenant in strict accordance with the terms hereof. Landlord and Tenant hereby agree not to conduct the transactions or communications contemplated by this Lease by electronic means, except by facsimile transmission as specifically set forth in Section 25(f); nor shall the use of the phrase "in writing" or the word "written" be construed to include electronic communications except by facsimile transmissions as specifically set forth in Section 25(f). The terms and conditions contained in this Lease shall inure to the benefit of and be binding upon the parties hereto, and upon their respective successors in interest and legal representatives, except as otherwise herein expressly provided. This Lease is for the sole benefit of Landlord and Tenant, and, other than Landlord's Mortgagee, no third party shall be deemed a third party beneficiary hereof.

(i) Quiet Enjoyment. Provided Tenant has performed all of its obligations hereunder, Tenant shall peaceably and quietly hold and enjoy the Premises for the Term, without hindrance from Landlord or any party claiming by, through, or under Landlord, but not otherwise, subject to the terms and conditions of this Lease.

(j) No Merger. There shall be no merger of the leasehold estate hereby created with the fee estate in the Premises or any part thereof if the same person acquires or holds, directly or indirectly, this Lease or any interest in this Lease and the fee estate in the leasehold Premises or any interest in such fee estate.

(k) No Offer. The submission of this Lease to Tenant shall not be construed as an offer, and Tenant shall not have any rights under this Lease unless Landlord executes a copy of this Lease and delivers it to Tenant.

(1) Entire Agreement. This Lease constitutes the entire agreement between Landlord and Tenant regarding the subject matter hereof and supersedes all oral statements and prior writings relating thereto. Except for those set forth in this Lease, no representations, warranties, or agreements have been made by Landlord or Tenant to the other with respect to this Lease or the obligations of Landlord or Tenant in connection therewith. The normal rule of construction that any ambiguities be resolved against the drafting party shall not apply to the interpretation of this Lease or any exhibits or amendments hereto.

(m) Waiver of Jury Trial. TO THE MAXIMUM EXTENT PERMITTED BY LAW, LANDLORD AND TENANT EACH WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY LITIGATION OR TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE ARISING OUT OF OR WITH RESPECT TO THIS LEASE OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO.

(n) Governing Law. This Lease shall be governed by and construed in accordance with the laws of the State of Minnesota.

(o) Recording. Tenant shall not record this Lease or any memorandum of this Lease without the prior written consent of Landlord, which consent may be withheld or denied in the sole and absolute discretion of Landlord, and any recordation by Tenant shall be a material breach of this Lease. Tenant grants to Landlord a power of attorney to execute and record a release releasing

any such recorded instrument of record that was recorded without the prior written consent of Landlord.

(p) Joint and Several Liability. If Tenant is comprised of more than one party, each such party shall be jointly and severally liable for Tenant's obligations under this Lease. All unperformed obligations of Tenant hereunder not fully performed at the end of the Term shall survive the end of the Term, including payment obligations with respect to Rent and all obligations concerning the condition and repair of the Premises.

(q) Financial Reports. Within 15 days after Landlord's request, Tenant will furnish Tenant's most recent audited financial statements (including any notes to them) to Landlord, or, if no such audited statements have been prepared, such other financial statements (and notes to them) as may have been prepared by an independent certified public accountant or, failing those, Tenant's internally prepared financial statements. If Tenant is a publicly traded corporation, Tenant may satisfy its obligations hereunder by providing to Landlord Tenant's most recent annual and quarterly reports. Tenant will discuss its financial statements with Landlord and, following the occurrence of an Event of Default hereunder, will give Landlord access to Tenant's books and records in order to enable Landlord to verify the financial statements. Landlord will not disclose any aspect of Tenant's financial statements that Tenant designates to Landlord as confidential except (1) to Landlord's Mortgagee or prospective mortgagees or purchasers of the Building, (2) in litigation between Landlord and Tenant, and/or (3) if required by court order. Tenant shall not be required to deliver the financial statements required under this Section 25(q) more than once in any 12-month period unless requested by Landlord's Mortgagee or a prospective buyer or lender of the Building or an Event of Default occurs.

(r) Landlord's Fees. Whenever Tenant requests Landlord to take any action not required of it hereunder or give any consent required or permitted under this Lease, Tenant will reimburse Landlord for Landlord's reasonable, out-of-pocket costs payable to third parties and incurred by Landlord in reviewing the proposed action or consent, including reasonable attorneys', engineers' or architects' fees, within 30 days after Landlord's delivery to Tenant of a statement of such costs. Tenant will be obligated to make such reimbursement without regard to whether Landlord consents to any such proposed action.

(s) Telecommunications. Tenant and its telecommunications companies, including local exchange telecommunications companies and alternative access vendor services companies, shall have no right of access to and within the Building, for the installation and operation of telecommunications systems, including voice, video, data, Internet, and any other services provided over wire, fiber optic, microwave, wireless, and any other transmission systems ("Telecommunications Services"), for part or all of Tenant's telecommunications within the Building and from the Building to any other location without Landlord's prior written consent. All providers of Telecommunications Services shall be required to comply with the rules and regulations of the Building, applicable Laws and Landlord's policies and practices for the Building. Tenant acknowledges that Landlord shall not be required to provide or arrange for any Telecommunications Services and that Landlord shall have no liability to any Tenant Party in connection with the installation, operation or maintenance of Telecommunications Services or any equipment or facilities relating thereto. Tenant, at its cost and for its own account, shall be solely responsible for obtaining all Telecommunications Services.

(t) Confidentiality. Tenant acknowledges that the terms and conditions of this Lease are to remain confidential for Landlord's benefit, and may not be disclosed by Tenant to anyone, by any manner or means, directly or indirectly, without Landlord's prior written consent. The consent by Landlord to any disclosures shall not be deemed to be a waiver on the part of Landlord of any prohibition against any future disclosure.

(u) Legal Fees. In the event of any litigation to enforce or interpret the terms hereof, the prevailing party shall be entitled to an award of its attorneys' fees and disbursements, through all appellate levels, and, as to Tenant, Landlord's attorneys' fees and disbursements shall constitute Rent hereunder. Notwithstanding the foregoing, if Landlord commences any action against Tenant which action settles in favor of Landlord at or prior to any trial in connection therewith, Landlord shall be entitled to recover from Tenant Landlord's attorneys' fees and disbursements and the same shall be payable by Tenant to Landlord with the next installment of Rent coming due and shall constitute Rent hereunder.

(v) Authority. Tenant (if a corporation, partnership or other business entity) hereby represents and warrants to Landlord that Tenant is a duly formed and existing entity qualified to do business in the state in which the Premises are located, that Tenant has full right and authority to execute and deliver this Lease, and that each person signing on behalf of Tenant is authorized to do so. Landlord hereby represents and warrants to Tenant that Landlord is a duly formed and existing entity qualified to do business in the state in which the Premises are located, that Landlord has full right and authority to execute and deliver this Lease, and that each person signing on behalf of Landlord is authorized to do so.

(w) Hazardous Materials. The term "Hazardous Materials" means any substance, material, or waste which is now or hereafter classified or considered to be hazardous, toxic, or dangerous under any Law relating to pollution or the protection or regulation of human health, natural resources or the environment, or poses or threatens to pose a hazard to the health or safety of persons on the Premises or in the Project. Tenant shall not use, generate, store, or dispose of, or permit the use, generation, storage or disposal of Hazardous Materials on or about the Premises or the Project except in a manner and quantity necessary for the ordinary performance of Tenant's business, and then in compliance with all Laws. If Tenant breaches its obligations under this Section 25(w), Landlord may immediately take any and all action reasonably appropriate to remedy the same, including taking all appropriate action to clean up or remediate any contamination resulting from Tenant's use, generation, storage or disposal of Hazardous Materials. Notwithstanding Landlord's indemnity contained in Section 11(d), Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against any and all claims, demands, liabilities, causes of action, suits, judgments, damages and expenses (including reasonable attorneys' fees and cost of clean up and remediation) arising from Tenant's failure to comply with the provisions of this Section 25(w). This indemnity provision shall survive termination or expiration of this Lease.
