2.             PREMISES.

In consideration of the rents and covenants herein agreed to be paid and performed, Landlord hereby leases to Tenant and Tenant hereby leases from Landlord, on the terms and conditions hereinafter set forth, that certain space (the “Premises”) consisting of approximately twenty-two thousand seven hundred eighty-nine (22,789) usable square feet and other improvements in a building (the “Building”) located at ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇-▇▇▇▇.

3.             TERM.

The term of this Lease shall be eighty-four (84) months commencing on June 15, 1995 (the “Commencement Date”), and ending at midnight on June 14, 2002, unless sooner terminated as hereinafter provided (the “Term”). Notwithstanding the foregoing, Landlord shall not be liable under this Lease Agreement for a failure to tender possession of the Premises to Tenant on the commencement date if such failure is attributable to reasons beyond Landlord’s control; and provided further, Tenant shall not be liable under this Lease Agreement until all utilities and services agreed to be furnished by Landlord are available for Tenants’ use.

4.             OPTION TO EXTEND LEASE

Tenant shall have the right and option (the “Option”) to extend this Lease for all (but not part) of the Premises, as hereinafter provided, for two (2) periods of three (3) years each (hereinafter referred to as “Renewal Term One” and “Renewal Term Two”) provided that (i) there is not then an Event of Default at the time of exercise of the Option nor at the commencement of either of the Renewal Terms; and (ii) that there has not been a material adverse change to Tenant’s financial status. Tenant’s right to extend for any Renewal Term shall lapse without further act or deed if Tenant has not exercised its option to extend for all available preceding Renewal Terms.

The Option shall be exercised by Tenant giving written notice to Landlord of Tenant’s intention to exercise said Option on or before that date which is not more than twelve (12) months nor less than nine (9) months prior to the then applicable expiration date for the Term. Unless Landlord has received such written notice of Tenant’s intention to exercise said Option within the time period specified herein, then Landlord shall have no further obligation to offer the Premises to the Tenant. If Tenant has not exercised its Option to extend the Terms as

1

outlined herein, Landlord shall be entitled to show the Premises at least nine (9) months prior to the expiration of each Term and offer the Premises for lease to any other prospective tenants. The Option contained herein is personal to Tenant and shall not be assigned or sublet to another party, except as to such party that purchases Tenant.

Rental rates will be at then Fair Market Rate, but, in no case, less than the current Base Rent then in effect for the Premises. The Fair Market Rent shall be established by agreement between Landlord and Tenant in accordance with the FAIR MARKET RENT DEFINITION section or, failing agreement, in accordance with the ARBITRATION PROCEDURES section.

Tenant shall have the right to terminate this Lease effective as of the expiration of the sixtieth (60th) month of the term upon nine (9) months prior written notice to Landlord and payment of a termination fee prior to the effective date of termination. The termination fee shall be (a) the then unamortized portion of any Tenant Leasehold Improvement Allowance (as defined in the TENANT LEASEHOLD IMPROVEMENT ALLOWANCE section) expended by Tenant, plus (b) the then unamortized portion of the brokers commissions (as defined in the BROKER section), plus (c) interest at ten percent (10%) per annum, plus (d) four (4) times the monthly rent in effect during the sixtieth (60th) month of the term. Additional Early Termination Fees will be proportionately added as applicable if Tenant elects to lease additional space as provided for herein.

During the first thirty-six (36) months of the term of this Lease, Tenant shall pay $5.77 per square foot per annum for Operating Expenses (as defined in the OPERATING EXPENSES section), payable monthly with Base Rent, subject to increase only to the extent that Tenant’s pro rata share of real estate taxes increase above $1.30 per square foot per annum. Effective at the beginning of month thirty-seven (37) of the Term, Tenant’s pro rata share of Operating Expenses shall reflect an increase in Operating Expenses equivalent to three percent (3%) per year for each of the preceding three years. On each January 1 of the Term thereafter, Tenant’s pro rata share

2

of Operating Expenses shall increase three percent (3%) over Tenant’s pro rata share for the previous year, with the exception of Tenant’s pro rata share of real estate taxes which shall reflect the actual increases.

Any items of additional rent shall be invoiced on a monthly basis by Landlord and shall be payable by Tenant within fifteen (15) days of the date of such invoice.

7.             OPERATING EXPENSES

(a)           Operating Expenses as Additional Rent. During the Term of the Lease, Tenant shall pay to Landlord as additional rent, without any set-off or deduction except as described herein, a prorata share (“Tenant’s Proportionate Share”) of all costs which Landlord may incur in owning, maintaining and operating the Building (“Operating Expenses”). Tenant’s Proportionate Share of Operating Expenses shall be that fraction, the numerator of which is the area of the Premises and the denominator of which is the total area of the Building (204,778 square feet).

(b)           Definition of Operating Expenses. The term “Operating Expenses” shall mean all of the following: (i) all of Landlord’s direct costs and expenses of operation, repair and maintenance of the Building, the property and the common areas and supporting facilities, as determined by Landlord in accordance with generally accepted accounting principles or other recognized accounting principles, consistently applied; (ii) costs, or a portion thereof, properly allocable to the Building, property or common areas of any capital improvements made to the Building, property or common areas by Landlord which comprise labor-saving devices or other equipment intended to improve the operating efficiency of any system within the Building, property or common areas (such as an energy management computer system) to the extent of cost savings in Operating Expenses as a result of the device or equipment, as reasonably determined by Landlord; and (iii) costs properly allocable to the Building, property or common areas of any capital improvements made to the Building, property or common areas by Landlord that are required under any governmental law or regulation that was not applicable to the Building, property and common areas at the time they were constructed, or that are reasonably required for the health and safety of tenants in the property or Building, the costs, or allocable portion thereof, to be amortized over its useful life as reasonably determined by Landlord and Tenant will pay Tenant’s Proportionate Share based on the time remaining in the lease term, together with interest upon the unamortized balance at the interest rate or such higher rate as may have been paid by Landlord on funds borrowed for the purpose of constructing the capital improvements.

3

percent (10%) of Operating Expenses; and the Real Property Taxes. If Landlord elects to self-insure or includes the Building under blanket insurance policies covering multiple properties, then the term “Operating Expenses” shall include the portion of the cost of such self-insurance properly allocated by Landlord to this Building.

(c)           Exclusions From Operating Expenses. The term “Operating Expenses” shall not include (i) costs paid directly by Tenant; (ii) principal and interest payments on loans secured by deeds of trust recorded against property; (iii) real estate sales or leasing brokerage commissions; or (iv) executive salaries of off-site personnel employed by Landlord except for the charge (or pro rata share) of the manager of the property and building; (v) any costs or expenses resulting from defective design or construction of the Building, or the presence of Hazardous Substances, except for such Hazardous Substances as are attributable to Tenant, (as described in Exhibit E) on the date hereof or at any time during the Term.

8.             TENANT LEASEHOLD IMPROVEMENT ALLOWANCE.

Landlord shall provide an allowance for the planning and design of Tenant Leasehold Improvements of up to a maximum of two thousand five hundred ($2,500) dollars.

Landlord will also provide an allowance for the construction of Tenant leasehold improvements (the “Tenant Leasehold Improvement Allowance”) of up to fifteen ($15.00) dollars per usable square foot. This Tenant Leasehold Improvement Allowance shall not exceed three hundred fifty-three thousand fifty-five ($353,055.00) dollars which also includes a fifteen dollar ($15.00) allowance per usable square foot for the December 15, 1995 expanded space. The Tenant Leasehold Improvement Allowance shall be the maximum contribution by Landlord for the cost of Tenant Leasehold Improvements. The Landlord Provided Work which is outlined on Exhibit G will not be included in this Tenant Leasehold Improvement Allowance.

Tenant shall have completed and submitted to Landlord its approved plan (Exhibit I) for Tenant Leasehold Improvements not less than ninety (90) days prior to the Commencement Date. Tenant and Landlord agree that changes to the plan may be submitted; however, any changes made or agreed to by Tenant after the 90th day prior to the Commencement Date which delay the occupancy of the Premises beyond the Commencement Date will be the sole responsibility of the Tenant and, in no case, will the Commencement Date originally agreed to herein be changed. It is further understood that Base and Additional Rent payments will begin on the Commencement Date so established. If Landlord does not complete the Tenant Leasehold Improvements by the Commencement Date to the reasonable satisfaction of Tenant for any reason other than Tenant changes after the 90th day prior to the Commencement Date, Tenant may, but is not obligated to, take possession of the Premises. If Tenant elects to take possession of the Premises but cannot conduct its business in the usual manner with respect to any portion of the Premises, Base Rent will be abated as to that portion of the Premises which cannot be utilized by Tenant in such usual manner. In no event shall Tenant’s obligation to pay rent be reduced by any unexpended amount of the Tenant Improvement Allowance. Tenant shall have the right to apply the Tenant Improvement Allowance only to costs and fees incurred by Tenant in the construction of the Tenant improvements. In no case, will such Tenant Improvement Allowance be used for the installation of phone and/or computer systems or the personal property of Tenant.

4

All such improvements and/or purchases utilizing this Tenant Leasehold Improvement Allowance will be deemed the sole property of the Landlord.

This Section of the Lease shall survive termination of the Lease.

9.             CONSTRUCTION OF LEASEHOLD IMPROVEMENTS

Tenant shall have the right to hire its own architect. Landlord will be responsible for the selection of the general and subcontractors, provided that all contractors and subcontractors shall be reasonably acceptable to Tenant. Landlord shall be responsible for supervision of completion of the Tenant Leasehold Improvements. Landlord will not charge any additional construction fees or any management fees related to the construction of the leasehold improvements unless Landlord serves as the general contractor, whereby, the Landlord’s general contracting fee and markups shall not exceed five percent (5%) of the total constructional costs and such additional fees will be disclosed in the bid. All work must conform to specified plans, code, ordinances and other legal requirements.

The same conditions shall apply to the construction of leasehold improvements pertaining to any additional and expansion option space later added to the initial Premises which shall be reasonably agreed to by Landlord and Tenant in order to effect occupancy by the due date.

10.           OPTION TO EXPAND

Tenant will have the first right to lease, upon three (3) months advance written notice to Landlord, a portion of the upper level of Building Two under the same terms and conditions with a term that runs coterminous with the Term of the Lease Agreement, hereinafter referred to as Expansion One and Expansion Two, according to the following:

(a)           Expansion One - up to three thousand one hundred sixty-four (3,164) usable square feet at the commencement of the twenty-fifth (25th) month of the Term. This Expansion One space is more particularly identified on the plan attached hereto as Exhibit A and made part of this Lease Agreement. For such Expansion One space Tenant shall pay (1) Base Rent of nine dollars and six cents ($9.06), Operating Expenses of four dollars and forty-seven cents ($4.47) and real estate taxes of one dollar thirty cents ($1.30) as stated in Section 6, plus (2) Tenant’s pro rata share of any actual increases in real estate taxes since the Commencement Date, plus (3) Tenant’s pro rata share of an increase in Operating Expenses of three percent (3%) for each year since the Commencement Date.

(b)           Expansion Two - up to an additional three thousand five hundred (3,500) usable square feet, which space shall be contiguous to and in reasonably the same proportion of internal and perimeter footage as the Premises, at the commencement of the forty ninth (49th) month of the Term. Rental rates for such Expansion Two space will be at then Fair Market Rent established by agreement between Landlord and Tenant in accordance with the FAIR MARKET RENT DEFINITION section or, failing agreement, in accordance with the ARBITRATION PROCEDURES section but, in no case, less than the lower of the two rental rates currently in effect for the initial Premises or the Expansion One space.

5

To the extent that Tenant does not exercise its option for the full amount of square feet of the first expansion space, the unused portion will be carried forward and added to the next option for expansion space.

Landlord will also provide a maximum Tenant Leasehold Improvement Allowance of up to fifteen dollars ($15.00) per usable square foot to be utilized for Expansion One and Expansion Two space. If less than this amount is expended by Landlord for leasehold improvements, then the Tenant’s rent as stated above, will be adjusted accordingly to reflect only that amount actually utilized. Tenant can utilize the expansion space Tenant Leasehold Improvement Allowance for leasehold improvements elsewhere in the Premises which are directly required to effect the expansion space operational changes. However, such Tenant Improvement Allowance will only be used for costs and fees incurred in the construction of Tenant improvements and not for the installation of phone and/or computer systems or the personal property of Tenant.

11.           FAIR MARKET RENT DEFINITION

“Fair Market Rent” shall mean the base rent that the Landlord would receive as of the commencement date in question if it were to lease to a tenant with a credit standing which Landlord reasonably determines is comparable to that of Tenant for similar sized space, similar leasehold improvements and similar other terms and conditions. For purposes of the determination of “Fair Market Rent,” it shall be assumed that Landlord and Tenant are each ready, willing and able to enter into such a lease but are under no compulsion to do so.

12.           ARBITRATION PROCEDURES

The parties to this Lease will initially attempt to agree upon the Fair Market Rate. If they have been unable to so agree within the period that they are required to agree as to such matter under the Lease, then either party may request by written notice to the other party (“Arbitration Request”) that the matter be determined by binding arbitration by an arbitration board consisting of three reputable MAI appraisers who are recognized experts regarding office leases in the Twin Cities area. One arbitrator will be appointed by each party, and each such arbitrator will have no material financial or other business interest in common with the party selecting such arbitrator. If a party fails to appoint an arbitrator and notify the other party of such appointment within thirty (30) days after the Arbitration Request is made, then the arbitrator that was appointed by the other party within such 30-day period will be the sole arbitrator. If two arbitrators are properly appointed and such first two arbitrators are unable to agree on a third arbitrator within thirty (30) days after the appointment of the second arbitrator, then such third arbitrator will be appointed by the presiding judge of ▇▇▇▇▇▇ County District Court, or by any person to whom such presiding judge formally delegates the matter, or, if such methods of appointment fail, by the American Arbitration Association.

The parties will submit a copy of this Lease to the sole arbitrator or the three arbitrators, as the case may be. In establishing the definition of Fair Market Rent, the arbitrator or arbitrators shall apply the standard described in the FAIR MARKET RENT DEFINITION section. If the arbitration is conducted by a sole arbitrator, such sole arbitrator will render his or her determination of the Fair Market Rate applicable during the period in question to the parties by the thirtieth (30th) day after the Arbitration Request was made. If the arbitration is conducted

6

by three arbitrators, each arbitrator will submit his or her determination(s) of the Fair Market Rate applicable during the period in question in a sealed envelope by the thirtieth (30th) day following appointment of the last arbitrator, and any determinations not submitted by such time shall be disregarded. In such cases, the parties will meet on such thirtieth (30th) day (or if it is not a business day, on the first business day thereafter) at the office of Landlord, or such other place as the parties may agree, and simultaneously deliver the determinations. If the determinations of at least two of the arbitrators are identical in amount, such amount will be deemed the decision of the arbitrators. If the determination of the three arbitrators are different in amount, the decision as to the Fair Market Rate will be independently determined as follows:

(i)            If neither the highest nor lowest determination differs from the middle determination by more than fifteen (15%) percent of such middle determination, then the decision will be deemed to be the average of the three determinations; and

(ii)           If clause (i) does not apply, then the decision will be deemed to be the average of the middle determination and the determination closest in amount to such middle determination.

The decision of the arbitrators, determined as above set forth, will be final and nonappealable. The fees and expenses of the arbitrator or arbitrators will be shared equally by Landlord and Tenant. During the period of time that any arbitration is pending under this Lease, the parties to this Lease will continue to comply with all those terms and provisions that are not the subject of the arbitration.

13.           LANDLORD PROVIDED WORK

Landlord will, at Landlord’s expense, provide for the work outlined on Exhibit G, Landlord Provided Work. Anything to the contrary in this Section notwithstanding, if Landlord does not complete for any reason, the Landlord Provided Work as described in Exhibit G by the dates specified therein, to the reasonable satisfaction of the Tenant, Tenant’s Base Rent shall be abated by twenty-five (25%) for each day until such Landlord Provided Work is completed.

14.           USE.

Tenant shall use the Premises only for general office, electronics design, manufacturing, storage and laboratory research (including laboratory research with rodents) or only as otherwise outlined and stated in this Lease, and for no other purpose without the Landlord’s prior written consent. Tenant shall not do, bring or keep anything in or about the Premises that will cause a cancellation of any insurance covering the Premises or the building in which the Premises are located. If the rate of any insurance carried by the Landlord is increased as a result of Tenant’s use, Tenant shall pay to Landlord within ten (10) days after written demand from Landlord, the amount of any such increase. Tenant shall comply with all laws concerning the Premises or Tenant’s use of the Premises, including without limitation, the obligation at Tenant’s cost to alter, maintain, or restore the Premises in compliance and conformity with all laws relating to the condition, use, or occupancy of the Premises by Tenant during the term of this Lease. Tenant shall not use or permit the use of the Premises in any manner that will tend to create waste or a nuisance or, if there shall be more than one tenant of the building containing the Premises, which shall unreasonably disturb any other tenant.

7

Subject to satisfactory completion of Tenant Leasehold Improvements, Tenant hereby accepts the Premises in their condition existing as of the date that Tenant possesses the Premises, subject to all applicable zoning, municipal, county and state laws, ordinances, regulations governing or regulating the use of the Premises and accepts this Lease subject thereto and to all matters disclosed thereby. Tenant hereby acknowledges that neither the Landlord nor the Landlord’s agent has made any representation or warranty to Tenant as to the suitability of the Premises for the conduct of Tenant’s business.

15.           TAXES.

(a)           Real Property Taxes.

Landlord shall pay all real property taxes and general assessments levied and assessed against the Premises during the Term of this Lease (other than assessments payable under an assessment agreement used in connection with tax increment financing).

(b)           Personal Property Taxes.

Tenant shall pay prior to the delinquency all taxes assessed against and levied upon the trade fixtures, furnishings, equipment and other personal property of Tenant contained in the Premises. Tenant shall endeavor to cause such trade fixtures, furnishings and equipment and all other personal property to be assessed and billed separately from the property of the Landlord. If any of Tenant’s said personal property shall be assessed with Landlord’s property, Tenant shall pay to Landlord the taxes attributable to Tenant within ten (10) days after receipt of a written statement from Landlord setting forth the taxes applicable to Tenant’s property.

(c)           Other Taxes

Tenant shall pay all taxes (whether characterized as a sales tax or otherwise) upon the Base Rent payable hereunder if it is clearly demonstrable from legislative history that such taxes are levied in lieu of real property taxes or additional real property taxes. Tenant shall not be obligated to pay any income, excess profits, estate, single business, inheritance, succession, transfer, franchise, capital or other tax assessments upon Landlord or, except as provided in this clause, upon the Base Rent or additional rent payable under this Lease.

16.           SERVICES.

(a)           Landlord agrees to provide during the Term, at no additional cost to Tenant, the services listed on Exhibit B, Section I. Landlord shall not be liable for full or partial stoppage or interruption of any of the above services, if such stoppage or interruption arises from conditions beyond Landlord’s reasonable control.

(b)           Additional services set forth on Exhibit B, Section II, are not available.

17.           MAINTENANCE AND REPAIRS.

(a)           Landlord’s Obligations. Except as provided in the DAMAGE OR DESTRUCTION section, and except for damage caused by any negligent or intentional act or

8

omission of Tenant, Tenant’s agents, employees, or invitees, Landlord at its sole cost and expense shall keep in good condition and repair the foundations, exterior walls, and exterior roof of the Premises. Landlord shall also maintain the electrical, plumbing and sewage fixtures and systems including, without limitation, those portions of the systems lying outside the Premises; window frames, gutters and down spouts on the building, all sidewalks, landscaping and other improvements that are a part of the Building or of which the Premises are a part. The Landlord shall also maintain the heating, ventilating and air-conditioning systems and the elevators servicing the Premises. Landlord shall have seven (7) days after notice from Tenant to commence to perform its obligations under this section, except that Landlord shall perform its obligations immediately if the nature of the problem presents a hazard or emergency situation. If Landlord fails to begin and diligently pursue maintenance and repair or if Landlord refuses or neglects to maintain or repair the Premises or parts of the Building affecting the Premises within seven (7) days of notice by Tenant to Landlord, and such failure to begin, refusal or neglect adversely affects Tenant’s ability to conduct its business, including without limitation Tenant’s ability to carry out its electronics manufacturing, Tenant may make the repairs necessary to permit it to conduct its business and Landlord shall pay to Tenant all actual and reasonable costs incurred by Tenant in making such repairs. If Landlord does not pay such amount to Tenant upon presentation to Landlord of a ▇▇▇▇ therefore, Tenant may offset such amount against future payments of Base Rent and additional rent in the order due.

(b)           Tenant’s Obligations. Subject to the provisions of Sub-paragraph (a) above and the DAMAGE OR DESTRUCTION section, Tenant at Tenant’s sole cost and expense shall keep in good order, condition and repair the Premises and every part thereof, including, without limitation, all Tenant’s personal property, fixtures, signs, store fronts, plate glass, show windows, doors, interior walls, interior ceiling, and lighting facilities.

If Tenant fails to perform Tenant’s obligations as stated herein, Landlord may at its option (but shall not be required to), enter the Premises, after ten (10) days prior written notice to Tenant, put the same in good order, condition and repair, and the costs thereof, together with interest thereon at the rate of ten (10%) percent per annum, shall become due and payable as additional rent to Landlord together with Tenant’s next rental installment.

18.           ADDITIONAL ALTERATIONS AND ADDITIONS.

Except for the Tenant Improvements as set forth in the TENANT LEASEHOLD IMPROVEMENT ALLOWANCE and CONSTRUCTION OF LEASEHOLD IMPROVEMENTS sections, Tenant shall not, without the Landlord’s prior written consent, make any alterations, improvements or additions in or about the Premises except for nonstructural work. As a condition to giving any such consent, the Landlord may require the Tenant to remove any such alterations, improvements, or additions at the expiration of the Term, and to restore the Premises to their prior condition by giving Tenant thirty (30) days written notice prior to the expiration of the Term that Landlord requires Tenant to remove any such alterations, improvements or additions that Tenant has made to the Premises. If Landlord so elects, Tenant at its sole cost shall restore the Premises to the condition designated by Landlord in its election before the last day of the Term of the Lease.

9

Before commencing any work relating to the alterations, additions, or improvements affecting the Premises, Tenant shall notify Landlord in writing of the expected date of the commencement of such work so that Landlord can post and record the appropriate notices of non-responsibility to protect Landlord from any mechanic’s liens, materialman liens, or any other liens. In any event, Tenant shall pay, when due, all claims for labor and materials furnished to or for Tenant at or for use in the Premises. Tenant shall not permit any mechanic’s liens or materialman’s liens to be levied against the Premises for any labor or material furnished to Tenant or claimed to have been furnished to Tenant or Tenant’s agents or contractors in connection with work of any character performed or claimed to have been performed on the Premises by or at the direction of Tenant. Tenant shall have the right to protest the validity of any such lien if, immediately on demand by Landlord, Tenant procures and records a lien release bond meeting the requirements of Minnesota law providing for the payment of any sum that the claimant may recover on the claim (together with the costs of suit, if it is recovered in the action).

Unless the Landlord requires their removal as set forth above, all alterations, improvements or additions which are made on the Premises by the Tenant shall become the property of the Landlord and remain upon and be surrendered with the Premises at the expiration of the Term. Notwithstanding the provisions of this paragraph, Tenant’s trade fixtures, furniture, equipment and other machinery, except for that included under the TENANT LEASEHOLD ALLOWANCE section, and other than that which is affixed to the Premises so that it cannot be removed without material or structural damage to the Premises, shall remain the property of the Tenant and removed by Tenant at the expiration of the term of this Lease.

19.           INSURANCE; INDEMNITY.

(a)           Fire Insurance.

Landlord at its cost shall maintain during the term of this Lease on the Premises a policy or policies of standard fire and extended coverage insurance to the extent of at least eighty (80%) percent of full replacement value thereof.

Tenant at its cost shall maintain during the term of this Lease on all its personal property, Tenant’s improvements, and alterations in or about the Premises, a policy of standard fire and extended coverage insurance, with vandalism and malicious mischief endorsements. The proceeds from any such policy shall be used by Tenant for the replacement of personal property or the restoration of Tenant’s improvements or alterations unless this Lease is terminated pursuant to the provisions hereof because of damage or destruction to the Premises or the Building.

10

The limits of such insurance shall not, however, limit the liability of Tenant hereunder. Both Landlord and Tenant shall be named as additional insureds. All public liability, property damage and other casualty insurance policies shall be written as primary policies, not contributing with, and not as excess to coverage which Landlord may carry. Prior to occupancy and thereafter, within at least fifteen (15) days of the expiration of any such policies, Tenant agrees to deliver to Landlord, certificates evidencing such insurance, provided said certificates contain an endorsement stating that such insurance cannot be modified or canceled, nor the amount thereof reduced, except upon thirty (30) days prior written notice to Landlord. If Tenant shall fail to procure and maintain such insurance the Landlord may, but shall not be required to, procure and maintain same at the expense of Tenant and the cost thereof, together with interest thereon at the rate of ten (10%) percent per annum, shall become due and payable as additional rental to Landlord together with Tenant’s next rental installment.

(c)           Waiver of Subrogation.

Tenant and Landlord each waives any and all rights of recovery against the other, or against the officers, employees, agents, and representatives of the other, for loss of or damage to such waiving party’s property or the property of others under its control, where such loss or damage is insured against under any insurance policy in force at the time of such loss or damage, even if such loss or damage may have been caused by the negligence (but not the willful act) of the other party or one for whom such party may be responsible. Each party shall cause each insurance policy obtained by it hereunder to provide that the insurance company waives all right of recovery by way of subrogation against either party in connection with any damage covered by any such policy.

(d)           Hold Harmless.

Tenant and Landlord shall each indemnify and hold the other harmless from and against any and all claims arising from the conduct of its business or from any activity, work, or things which may be permitted or suffered by either in or about the Premises or Building including all damage, costs, attorney’s fees, expenses and liabilities incurred in the defense of any claim or action or proceeding arising therefrom unless arising from the willful misconduct or gross negligence of the other party or the employees or agents of the other party.

(e)           Exemption of Landlord from Liability.

Landlord shall not be liable to Tenant for any damages arising solely from any act or neglect of any other tenant, if any, of the Building in which the Premises are located.

20.           DAMAGE OR DESTRUCTION.

(a)           Damage - Insured.

If, during the term of this Lease, the Premises and/or the Building are totally or partially destroyed rendering the Premises totally or partially inaccessible or unusable, and such damage or destruction was caused by a casualty covered under an insurance policy required to be maintained hereunder, Landlord shall restore the Premises and/or the building and other improvements in which the Premises are located into substantially the same condition as they

11

were in immediately before such damage or destruction, provided that the restoration can be made under the existing laws and can be completed within one hundred twenty (120) days after the date of such destruction or damage.

If the existing laws do not permit the restoration, either party can terminate this Lease immediately by giving notice to the other party.

(b)           Damage - Uninsured.

In the event that the Premises are damaged or destroyed by a casualty which is not covered by the fire and extended coverage insurance which is required to be carried by the party designated in the INSURANCE; INDEMNITY section above, then Landlord shall restore the same; provided that if the damage or destruction is to an extent greater than ten (10%) percent of the then replacement cost of the improvements on the Premises (exclusive of Tenant’s trade fixtures and equipment and exclusive of foundations and footings), then Landlord may elect not to restore and to terminate this Lease. Landlord must give to Tenant written notice of its intention not to restore within thirty (30) days from the date of such damage or destruction and, if not given, Landlord shall be deemed to have elected to restore and in such event shall repair any damage as soon as reasonably possible. In the event that Landlord elects to give such notice of Landlord’s intention to cancel and terminate this Lease, Tenant shall have the right, within ten (10) days after receipt of such notice, to give written notice to Landlord of Tenant’s intention to repair such damage at Tenant’s expense, without reimbursement from Landlord, in which event the Lease shall continue in full force and effect and Tenant shall proceed to make such repairs as soon as reasonably possible. If the Tenant does not give such notice within such 10 day period, this Lease shall be canceled and be deemed terminated as of the date of the occurrence of such damage or destruction.

(c)           Damage Near the End of the Term.

If the Premises are totally or partially destroyed or damaged during the last twelve (12) months of the Term of this Lease or any renewals of this Lease, Landlord may, at Landlord’s option, cancel and terminate this Lease as of the date of the cause of such damage by giving written notice to Tenant of Landlord’s election to do so within 30 days after the date of the occurrence of such damage; provided, however, that, if the damage or destruction occurs within the last twelve (12) months of the Term and if within fifteen (15) days after the date of such damage or destruction Tenant exercises any option to extend the term provided herein, Landlord shall restore the Premises if obligated to do so as provided in subparagraph (a) or (b) above.

12

(d)           Abatement of Rent.

If the Premises are partially or totally destroyed or damaged and Landlord or Tenant repairs or restores them pursuant to the provisions of this section, the rent payable from the date of such damage and for the period during which such damage, repair or restoration continues shall be abated in proportion to the degree to which Tenant’s reasonable use of the Premises is impaired. Except for the abatement of rent, if any, Tenant shall have no claim against Landlord for any damages suffered by reason of any such damage, destruction, repair or restoration.

(e)           Trade Fixtures and Equipment

If Landlord is required or elects to restore the Premises as provided in this section, Landlord shall not be required to restore Tenant’s improvements, trade fixtures, equipment or alterations made by Tenant, such excluded items being the sole responsibility of Tenant to restore hereunder.

21.           PARKING AND TENANT ENTRANCE

At no additional cost, Landlord agrees to maintain (including snow removal when appropriate) and allow Tenant to use a general parking and entrance area for Tenants’ use and for Tenants’ visitors’ use. The area the entrance and parking spaces are located in is designated on Exhibit C.

22.           CONDEMNATION.

If the Premises or any portion thereof are taken by the power of eminent domain, or sold by Landlord under the threat of exercise of said power (all of which is herein referred to as “condemnation”), this Lease shall terminate as to the part so taken as of the date the condemning authority takes title or possession, whichever occurs first. If more than twenty (20%) percent of the floor area of the Building, or more than twenty (20%) percent of the land on which the Building is located is taken by condemnation, unless such taking does not affect Tenant’s use of the Premises, either Landlord or Tenant may terminate this Lease as of the date the condemning authority takes possession by notice in writing of such election within twenty (20) days after Landlord shall have notified Tenant of such taking or, in the absence of such notice, then within twenty (20) days after the condemning authority shall have taken possession.

If this Lease is not terminated by either Landlord or Tenant as provided herein above, then it shall remain in full force and effect as to the portion of the Premises remaining, provided that the rental shall be reduced in proportion to the floor area of the buildings taken within the Premises as bears to the total floor area of all buildings located on the Premises. In the event this Lease is not so terminated, then Landlord agrees at Landlord’s sole cost and expense, to as soon as reasonably possible, restore the Premises to a complete unit of like quality and character as existed prior to the condemnation.

All awards for the taking of any part of the Premises or any payment made under the threat of the exercise of the power of· eminent domain shall be the property of the Landlord, whether made as compensation for the diminution of the value of the leasehold or for the taking of the fee or as severance damages; provided, however, that Tenant shall be entitled to any award

13

for loss of or damage to Tenant’s trade fixtures and removable personal property, good will and going-concern value.

Rent, including additional rent, shall be abated or reduced during the period from the date of taking until the completion of restoration by Landlord, but all other obligations of Tenant under this Lease shall remain in full force and effect. The abatement or reduction of the rent shall be based on the extent to which the restoration interferes with Tenant’s use of the Premises.

23.           ASSIGNMENT AND SUBLETTING.

Landlord’s rights under this Lease may be assigned or conveyed without notice to Tenant, but such assignment or conveyance shall not relieve Landlord of any of its obligations hereunder and shall not be valid as to Tenant until ten (10) days after Tenant receives written notice thereof. Tenant shall not voluntarily or by operation of law assign, transfer, sublet, mortgage, or otherwise transfer or encumber all or any part of Tenant’s interest in this Lease or in the Premises without Landlord’s prior written consent which consent shall not be unreasonably withheld or delayed, provided that Tenant shall have the right to transfer, with notice but without consent, to any entity which acquires all or substantially all of the assets of Tenant or to an entity controlled by, controlling or under common control of Tenant. Any attempted assignment, transfer, mortgage, encumbrance, or subletting without such consent shall be void and shall constitute a breach of this Lease. Tenant’s extension rights in this Lease Agreement are not assignable. Regardless of Landlord’s consent, no subletting or assignment shall release Tenant of Tenant’s obligation to pay the rent and to perform all other obligations to be performed by Tenant hereunder for the term of this Lease. The acceptance of rent by Landlord from any other person shall not be deemed a waiver by Landlord of any provision hereof. Consent to one assignment or subletting shall not be deemed consent to any subsequent assignment or subletting.

24.           DEFAULT

(a)           Events of Default.

The occurrence of any one or more of the following events shall constitute a default and breach of this Lease by Tenant:

(1)           Failure to pay rent when due, if the failure continues for five (5) days after written notice has been given to Tenant.

(2)           Tenant shall be considered in default under the Lease for the abandonment of the Premises if the Premises are not kept in an orderly condition and the rent is not paid in accordance with the terms of the lease.

(3)           Failure to perform any other provision of this Lease if the failure to perform is not cured within thirty (30) days after written notice thereof has been given to Tenant by Landlord. If the default cannot reasonably be cured within said thirty (30) day period, Tenant shall not be in default under this Lease if Tenant commences to cure the default within the thirty (30) day period and diligently prosecutes the same to completion.

14

(4)           The making by Tenant of any general assignment, or general arrangement for the benefit of creditors; the filing by or against Tenant of a petition to have Tenant adjudged a bankrupt or a petition for reorganization or arrangement under any law relating to bankruptcy unless the same is dismissed within sixty (60) days; the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in the Lease, where possession is not restored to Tenant within thirty (30) days; or the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in the Lease, where such seizure is not discharged within thirty (30) days.

Notices given under this paragraph shall specify the alleged default and the applicable lease provisions, and shall demand that Tenant perform the provisions of this Lease or pay the rent that is in arrears as the case may be, within the applicable period of time. No such notice shall be deemed a forfeiture or a termination of this Lease unless Landlord so elects in the notice.

(b)           Landlord’s Remedies.

The Landlord shall have the following remedies if Tenant commits a default under this Lease. These remedies are not exclusive but are cumulative and in addition to any remedies now or hereafter allowed by law.

Landlord can continue this Lease in full force and effect, and the Lease will continue in effect so long as Landlord does not terminate Tenant’s right to possession, and the Landlord shall have the right to collect rent when due. During the period that Tenant is in default, Landlord can enter the Premises and relet them, or any part of them, to third parties for Tenant’s account. Tenant shall be liable immediately to the Landlord for all costs the Landlord incurs in reletting the Premises, including, without limitation, brokers’ commissions, expenses of remodeling the Premises required by the reletting, and like costs. Reletting can be for a period shorter or longer than the remaining term of this Lease. Tenant shall pay to Landlord the rent due under this Lease on the dates the rent is due, less the rent Landlord receives from any reletting. No act by Landlord allowed by this paragraph shall terminate this Lease unless Landlord notifies Tenant that Landlord elects to terminate this Lease. After Tenant’s default and for so long as Landlord has not terminated Tenant’s right to possession of the Premises, if Tenant obtains Landlord’s consent, Tenant shall have the right to assume or sublet its interest in the Lease, but Tenant shall not be released from liability. Landlord’s consent to the proposed assignment or subletting shall not be unreasonably withheld.

If Landlord elects to relet the Premises as provided in this paragraph, any rent that Landlord receives from such reletting shall apply first to the payment of any indebtedness from Tenant to Landlord other than the rent due from Tenant to Landlord; secondly, to all costs, including maintenance, incurred by Landlord in such reletting; and third, to any rent due and unpaid under this Lease. After deducting the payments referred to in this paragraph, any sum remaining from the rent Landlord receives from such reletting shall be held by Landlord and applied in payment of future rent as rent becomes due under this Lease. In no event shall tenant be entitled to any excess rent received by Landlord. If, on the date rent is due under this Lease, the rent received from the reletting is less than the rent due on that date, Tenant shall pay to

15

Landlord, in addition to the remaining rent due, all costs, including maintenance, that Landlord shall have incurred in reletting that remain after applying the rent received from the reletting as provided in this paragraph.

If Tenant is in default and such default is continuing, Landlord can terminate Tenant’s right to possession of the Premises at any time at Landlord’s option. No act by Landlord other than giving written notice to Tenant shall terminate this Lease. Act of maintenance or efforts to relet the Premises shall not constitute a termination of Tenant’s right to possession.

In the event of termination of Tenant’s right to possession of the Premises, Landlord has the right to recover from Tenant:

(1)           The unpaid rent that had been earned at the time of termination of this Lease;

(2)           As and for liquidated and agreed final damages for Tenant’s default (the “Final Damages”), an amount equal to the then present value of the excess of the Base Rent, Additional Rent and other sums or charges reserved under this Lease from the day of such default through what would be the then unexpired Term if the same had remained in effect, less proceeds of reletting, said present value to be arrived at on the basis of a discount rate of eight percent (8%) per annum. Landlord will use reasonable effort to promptly re-lease the Premises at Fair Market Rent. If Landlord and Tenant cannot agree on the Fair Market Rent for purposes of this clause, Fair Market Rent shall be established in accordance with the FAIR MARKET RENT DEFINITION section or, failing agreement, in accordance with the ARBITRATION PROCEDURES section; and

(3)           Costs of collection and reasonable attorneys’ fees in connection with termination and recovery.

At any time after an Event of Default occurs and is continuing hereunder, Landlord can cure the default at Tenant’s cost and expense. If Landlord at any time, by reason of Tenant’s Event of Default, pays any sum or does any act that requires the payment of any sum, the sum paid by Landlord shall be due immediately from Tenant to Landlord at the time the sum is paid, and if paid at a later date shall bear interest at the maximum rate an individual is permitted by law to charge from the date the sum is paid by Landlord until Landlord is reimbursed by Tenant. The sum, together with interest thereon, shall be considered additional rent.

25.           SIGNS.

Tenant will be allowed a building standard (approximately 1’ by 1’) suite sign, a directional sign at the top of the south entrance stairwell and signage on a new monument sign to be erected by the Landlord on the south boulevard for the Term and any renewal Term of this Lease Agreement. Tenant will be responsible for the cost of placement, replacement and maintenance of its lettering, including removal at Lease termination, over the life of the Lease. Such installation of monument signage shall be completed as designated in Exhibit G.

Tenant shall not have the right to place, construct or maintain any additional sign, advertisement, awning, banner, or other exterior decorations on the building or property of the Landlord or other improvements that are a part of the Premises without Landlord’s prior, written

16

consent. Any signs that are placed on the Landlord’s property or the Premises shall be at the sole expense of Tenant and shall conform with all applicable zoning laws. Tenant agrees to maintain its signs in good repair, to remove its signs at the end of the term or any intended term, repairing any damage caused by such removal, and to hold Landlord harmless from any loss, cost or damages resulting from the erection, existence, maintenance or removal of Tenant’s signs.

Landlord has no intent, at the current time, of changing the name of the Building on behalf of another tenant, however, Landlord reserves the right to do so. In no case, will Landlord allow signage, other than the building address, to be placed on the entrance canopy. If Landlord allows any tenant to place signage on the south entrance vestibule, Landlord will give the Tenant the option of placing similar style signage on the south entrance vestibule.

26.           SUBORDINATION.

This Lease, at Landlord’s option, shall be subordinate to any ground lease, mortgage, deed of trust, or any other hypothecation for security now or hereafter placed upon the real property of which the Premises are a part and to any and all advances made on the security thereof and to all renewal, modifications, and extensions thereof. Notwithstanding any such subordination, Tenant’s right to quiet possession of the Premises shall not be disturbed if Tenant is not in default and so long as Tenant shall pay the rent and observe and perform all the other provisions of this Lease, unless this Lease is otherwise terminated pursuant to its terms. If any mortgagee, trustee, or ground lessor shall elect to have this Lease prior to the lien of its mortgage or deed of trust or ground lease, and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such mortgage, deed of trust or ground lease, whether this Lease is dated prior to or subsequent to the date of such mortgage, deed of trust or ground lease, or the date of recording thereof. Tenant agrees to execute any documents required to effect such subordination or to make this Lease prior to the lien of any mortgage, deed of trust, or ground lease, as the case may be, and failing to do so within ten (10) days after written demand from Landlord does hereby make, constitute and irrevocably appoint Landlord as Tenant’s attorney in fact and in Tenant’s name, place and stead to do so provided that Tenant shall have received a customary non disturbance agreement from the mortgagee, trustee, or ground lessor.

27.           SURRENDER.

On the last day of the term hereof, or on any sooner termination, Tenant shall surrender the Premises to Landlord in good condition, broom clean, ordinary wear and tear excepted. Tenant shall repair any damage to the Premises occasioned by its use thereof, or by the removal of Tenant’s trade fixtures, furnishings and equipment which repair shall include the patching and filling of holes and repair of structural damage. Tenant shall remove all of its personal property and fixtures on the Premises prior to the expiration of the term of this Lease and if required by Landlord pursuant to the ADDITIONAL ALTERATIONS AND ADDITIONS section, subsection (a), above, any alterations, improvements or additions made by Tenant to the Premises. If Tenant fails to surrender the Premises to Landlord on the expiration of the Lease as required by this paragraph, Tenant shall hold Landlord harmless from all damages resulting from Tenant’s failure to vacate the Premises, including, without limitation, claims made by any succeeding tenant resulting from Tenant’s failure to surrender the Premises.

17

28.           HOLDING OVER.

If the Tenant, with the Landlord’s consent, remains in possession of the Premises after the expiration or termination of the Term of this Lease, such possession by Tenant shall be deemed to be a tenancy from month-to-month at a rental of one hundred fifty percent (150%) the amount of the last monthly rental plus all other charges payable hereunder, upon all the provisions of this Lease applicable to month-to-month tenancy. If Landlord’s consent to holding over is not given, Tenant shall become a tenant-at-sufferance.
