SECTION 1 DEMISE AND PREMISES

1.1 Demise

Landlord hereby leases to Tenant and Tenant hereby leases from Landlord, upon the terms and conditions set forth in this Lease, the Premises described in Section 1.2 in the Building described in the Summary of Fundamental Provisions (the “Building”). The Building is located upon the land described on the attached Exhibit B (the “Land”). The Land, the Building, and all other improvements on the Land whether now in existence or constructed during the term of this Lease are part of Sunset Center at Tanasbourne (the “Project”).

1.2 Premises

The Premises (the “Premises”) leased to Tenant are identified by the outlining on the floor plan(s) attached as Exhibit A and are described in the Summary of Fundamental Provisions.

1.3 Commencement and Expiration Dates

The term of this Lease shall commence on the earlier of (a) the date on which Tenant takes possession of the Premises or (b) the date on which Landlord’s work, if any, in the Premises as described in the Work Agreement attached as Exhibit C to the Lease (“Landlord’s Work”) is substantially completed. If Landlord is unable to give possession of the Premises on the estimated commencement date set forth in the Summary of Fundamental Provisions, Landlord shall not be subject to any liability, and the validity of this Lease shall not be impaired under such circumstances, but Base Rent and Additional Rent shall be abated (provided Tenant is not responsible for the delay) until Landlord has given notice to Tenant that the Premises are ready for Tenant’s possession. If Landlord has given Tenant permission to take possession of the Premises prior to the date on which Landlord’s Work is substantially completed, such possession shall be deemed to be upon all the terms, covenants, conditions and provisions of this Lease, including, without limitation, the payment of Base Rent and the Additional Rent. The term of this Lease shall expire, unless sooner terminated pursuant to the provisions of this Lease, sixty-six (66) months after the Commencement Date (the “Expiration Date”).

All Rents shall be paid in lawful money of the United States to Landlord at its office set forth in the Summary of Fundamental Provisions, or such other place as Landlord shall designate by written notice to Tenant. Tenant shall pay all Rents promptly when due without notice or demand therefor and without any abatement, deduction or setoff, for any reason whatsoever, except as may be expressly provided in this Lease. If the Commencement Date occurs on a day other than the first day of a calendar month, the Rents for that partial calendar month shall be prorated based on the number of days in such month.

2.2 Base Rent

The Base Rent shall be as set forth in the Summary of Fundamental Provisions.

SECTION 3 ADDITIONAL RENT

3.1 Operating Expenses

Tenant agrees to pay its Proportionate Share of all increases in Operating Expenses in excess of those incurred by Landlord during the Base Year. Tenant’s Proportionate Share of Operating Expenses is set forth in the Summary of Fundamental Provisions and is determined by dividing the number of rentable square feet in the Premises by the number of rentable square feet in the Building. The term “Operating Expenses” shall mean all costs, fees, and expenses paid or incurred by Landlord or on Landlord’s behalf as determined by Landlord to be necessary or appropriate for the efficient operation, maintenance, repair, replacement, management, administration and insurance of the Project and the curbs, sidewalks, common areas, parking garage, and plazas adjoining the Project, except for Taxes which shall be paid in accordance with Sections 3.3 and 4 below.

3.1.12 The costs of any capital improvements or repairs to the Project and/or of any machinery or equipment installed in the Project amortized over the useful life of the improvements, machinery and/or equipment as estimated by Landlord, which is made or becomes operational, as the case may be, after the completion of the initial construction of the Building.

3.1.13 ~~The rental costs or rental value of the management offices serving the Project~~;

3.1.14 Legal, accounting and other professional fees incurred in connection with operation, maintenance and management of the Project; and

3.3 Taxes

Tenant agrees to pay its Proportionate Share of all increases in Taxes (as defined below) in excess of the Taxes payable by Landlord during the Base Year. Tenant’s Proportionate Share of Taxes shall be the same as Tenant’s Proportionate Share of Operating Expenses, as provided in Section 3.1 of this Lease. “Taxes” shall mean all taxes and assessments of all public, quasi-public, and governmental authorities and owner associations against the Project or the ownership, management, or operation of the Project, all rent taxes, local improvement districts, special and general assessments, gross receipts taxes, taxes on Landlord’s interest under this Lease, all taxes in lieu of or in addition to the foregoing, whether or not such taxes are now in effect (excluding, however, any tax based upon Landlord’s net income and any inheritance taxes), and the cost of contesting any such taxes or assessments.

SECTION 4 PAYMENT OF ADDITIONAL RENT

4.1 Written Statement of Estimate

Prior to the beginning of each calendar year during the term of this Lease after the Base Year, or as soon thereafter as practical, Landlord shall furnish Tenant with a written statement setting forth Tenant’s Proportionate Share of the increase in the estimated Operating Expenses and Taxes for the next calendar year. Failure of Landlord to deliver the statement of estimated Operating Expenses and Taxes shall not relieve Tenant of its obligation to pay Tenant’s Proportionate Share of Operating Expenses and Taxes. Tenant shall each month pay to Landlord as Additional Rent an amount equal to Tenant’s Proportionate Share as shown in Landlord’s written statement.

4.2 Final Written Statement

Within ninety (90) days after the close of each calendar year after the Base Year during the term of this Lease, or as soon thereafter as practical, Landlord shall deliver to Tenant a written statement (the “Operating Statement”) setting forth Tenant’s actual Proportionate Share of the increases, if any, in Operating Expenses and of the Taxes for the preceding calendar year over the Base Year. In the event Tenant’s share of the actual Operating Expenses is in excess of the amount actually paid by Tenant for Operating Expenses on an estimated basis for the year in question, Tenant shall pay the amount of such deficiency to Landlord within thirty (30) days following the date of such statement. In the event Tenant’s share of actual Operating Expenses is less than the amount actually paid by Tenant for Operating Expenses on an estimated basis for the year in question, then Landlord shall either apply the overpayment to Tenant’s next Rent payment, or promptly reimburse the excess to Tenant. In the event Tenant’s share of the actual Taxes is in excess of the amount actually paid by Tenant for Taxes on an estimated basis for the year in question, Tenant shall pay the amount of such deficiency to Landlord within thirty (30) days following

the date of such statement. In the event Tenant’s share of actual Taxes is less than the amount actually paid by Tenant for Taxes on an estimated basis for the year in question, then Landlord shall either apply the overpayment to Tenant’s next Rent payment, or promptly reimburse the excess to Tenant. In no event shall Base Rent decrease pursuant to the provisions of Section 3 or Section 4 of this Lease.

4.3 Adjustment for Reduced Occupancy

If during any calendar year, less than 95 percent of the rentable area of the Building is occupied, Landlord’s estimation and determination of Operating Expenses shall be based on Landlord’s estimate of Operating Expenses as if the Building were at least 95 percent occupied. Landlord shall use sound accounting and management principles to make appropriate adjustments in occupancy-related Operating Expenses for the year in question for the purpose of avoiding distortion in the amount of Operating Expenses by reason of variation in the total occupancy of the Building. The amount so determined by Landlord shall be deemed to be the Operating Expenses for the Building for the year in question.

4.4 Tenant Examination

Any objections by Tenant to the Operating Statement shall be made in writing given to Landlord within 60 days after the Operating Statement is submitted to Tenant. If no objections are made within such time period, the Operating Statement shall be conclusive and binding on Tenant. If Tenant makes any such objection within the time period required by this Section 4.4, Tenant shall have the right to inspect, at Tenant’s sole cost and expense, Landlord’s records pertaining to the computation of Operating Expenses and Taxes, so long as the following provisions are complied with: (a) Tenant shall perform such inspection within 75 days following the receipt of the Operating Statement pertaining to the year in question, (b) Tenant shall provide to Landlord a copy of the inspection report, (c) Tenant shall keep the report confidential and shall not share the contents, results, or the fact that Tenant is investigating the Operating Expenses or the Taxes, or adjustments with any other person, except for its advisors on a need-to-know basis, and (d) Tenant shall pay to Landlord within ten (10) days following its inspection any amount determined to be owing by Tenant. Tenant’s inspection may only be conducted by Tenant’s employees, advisors or by Tenant’s certified public accountant paid on an hourly basis (and not a contingent fee basis). Landlord agrees to pay Tenant any amount determined to be owing to Tenant within ten (10) days following Landlord’s receipt of the inspection report or, if Landlord does not agree with Tenant’s inspection report, as determined by an independent certified public accountant within ten (10) days following the date on which a report by such independent certified public accountant is given to Landlord and Tenant. Such independent certified public accountant shall be selected by Landlord and approved in advance by Tenant, which approval shall not be unreasonably withheld.

SECTION 5 SECURITY DEPOSIT

Tenant has deposited with Landlord the sum shown on the Summary of Fundamental Provisions as security for the full and faithful performance by Tenant of Tenant’s obligations under this Lease. The security deposit shall not earn interest, and shall not be considered an advance payment of rent or a measure of Landlord’s damages in the event of a default by Tenant. If Tenant defaults in the performance of any of Tenant’s obligations under this Lease, including the payment of Rents, Landlord may, but shall not be obligated to, use, apply or retain all or any part of the security deposit to the extent required for the payment of any sum in default. If Landlord shall so use, apply or retain all or any part of the security deposit, Tenant shall upon demand immediately deposit with Landlord a sum equal to the amount so used, applied or retained. If Tenant shall fully and faithfully comply with all of Tenant’s obligations under this Lease, the security deposit or any balance thereof shall be paid to Tenant within thirty (30) days after the date on which this Lease shall expire or sooner terminate, and after delivery to Landlord of possession of the Premises and after all payments required to be made by Tenant in this Lease, have been paid.

SECTION 6 USE

6.1 General

Tenant shall use ~~and occupy~~ the Premises ~~continuously~~ during the term of this Lease for general office use and for no other purpose without the prior written consent of Landlord. If any governmental license or

permit shall be required for the proper and lawful conduct of Tenant’s business in the Premises, Tenant, at its expense, shall procure, maintain and comply with the terms and conditions of each such license or permit. Tenant shall, at Tenant’s expense, comply with all laws, codes, rules, statutes, regulations, orders and other requirements of public authorities (“Laws”) relating to Tenant’s use and occupancy of the Premises.

6.2 Negative Covenants as to Use

Tenant shall not, without the prior written consent of Landlord, use any apparatus, machinery or device in or about the Premises which will cause any noise, vibration, fumes or electronic interference or which will overload the floors or structure of the Premises. Tenant shall not at any time use or occupy, or suffer or permit anyone to use or occupy the Premises, or permit anything to be done in the Premises, in any manner which:(a) violates the Certificate of Occupancy for the Premises or for the Building; or (b) causes or is liable to cause injury to the Premises or the Building or any equipment, facilities or systems therein; or (c) constitutes a violation of Laws or the requirements of insurance bodies; or (d) impairs or tends to impair the character, reputation or appearance of the Building as a first-class office building; or (e) impairs or tends to impair the proper and economic maintenance, operation and repair of the Building and/or its equipment, facilities or systems; or (f) annoys or inconveniences or tends to annoy or inconvenience other tenants or occupants of the Project; or (g) generates, releases, stores, or deposits on or about the Premises any environmentally hazardous or toxic substances, materials, wastes, pollutants, oils, or contaminants, as defined by any Law.

SECTION 7 SUBORDINATION

This Lease, and all rights of Tenants hereunder, are and shall be subject and subordinate to any ground leases or master leases (“Master Leases”) covering the Land and/or the Building now or hereafter existing, and to all mortgages, trust deeds and other financing and security instruments (“Mortgages”), which may now or hereafter affect the Land and/or the Building, and to all renewals, modifications, replacements and extensions of such Master Leases and Mortgages. This Section shall be self-operative, and no further instrument of subordination shall be required. In confirmation of such subordination, Tenant shall execute, acknowledge and deliver to Landlord any instrument that Landlord may reasonably request to evidence such subordination within ten days after a request therefor. If the interest of Landlord under this Lease is transferred, whether through possession, foreclosure or delivery of a new lease or deed, then Tenant shall recognize the party succeeding to Landlord’s rights and obligations (the “Successor Landlord”) as the Landlord under this Lease and shall promptly execute and deliver any instrument that such Successor Landlord may reasonably request to evidence such attornment. Upon such attornment, Tenant’s rights hereunder shall continue in full force and effect as a direct Lease between the Successor Landlord and Tenant upon all of the terms, conditions and covenants as set forth in this Lease so long as Tenant is not in default. Landlord shall use commercially reasonable effort to obtain customary nondisturbance agreements from holders of encumbrances in the building.

SECTION 8 TRANSFERS BY TENANT

8.1 General

Tenant shall not assign this Lease or any interest therein, or sublet the Premises or any part thereof, or mortgage, encumber or otherwise transfer or dispose of Tenant’s interest in the Premises, either voluntarily or involuntarily, without the prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed. If Tenant requests consent to a proposed transfer, Tenant shall pay for Landlord’s reasonable legal and administrative expenses incurred in reviewing the request for consent to transfer. Consent to one such transfer shall not imply any future consent, and all subsequent transfers shall be made only upon obtaining prior written consent of Landlord. Assignees shall become directly liable to Landlord for all obligations of Tenant hereunder, but Tenant shall remain liable for all obligations under this Lease.

It shall be the responsibility of Tenant to provide Landlord, in a manner reasonably acceptable to Landlord, with such information as Landlord determines is necessary for Landlord to grant or withhold its consent. Landlord may withhold its consent if the proposed transferee fails to satisfy the criteria then generally (but not necessarily

uniformly) used by Landlord in selecting new tenants, which criteria may include, without limitation, financial capability, business reputation, business experience, ~~existing and future space requirements~~ of ~~other tenants, existing and future space requirements of the proposed transferee~~, the intended use, and the anticipated demand for services by the transferee., ~~and the transferee’s anticipated contribution to the prestige of the Project.~~ Landlord shall not be obligated to approve a transfer to an existing Project tenant or another party with whom Landlord has been negotiating to lease space in the Project.

Landlord shall have fifteen (15) ~~thirty~~ ~~(30)~~ days following receipt of Tenant’s notice to make an election to recapture under this Section 8.2. ~~Landlord may require Tenant to assign or sublease to Landlord all or any portion of the Premises Tenant desires to assign or sublease.~~ In the event Landlord shall elect to recapture all or any portion of the Premises, Base Rent shall be reduced by a fraction the numerator of which is the Net Rentable area of that portion of the Premises being recaptured by Landlord and the denominator of which is the total Net Rentable area of the Premises.

8.3 Landlord’s Option to Increase Rent

SECTION 29 MISCELLANEOUS

29.1 Entire Agreement

All understandings and agreements between the parties are merged in this Lease and neither party is relying upon any statement or representation not embodied in this Lease. No agreement shall be effective to change or modify this Lease, unless such agreement is in writing, refers expressly to this Lease and is signed by the party against whom enforcement is sought.

29.2 Successors and Assigns

Except as otherwise expressly provided in this Lease, the obligations of this Lease bind and benefit the successors and assigns of the parties.

29.3 Nonrecourse Lease

Tenant shall look only to Landlord’s estate and property in the Land and the Building (or the proceeds thereof) for the satisfaction of Tenant’s remedies for the collection of a judgment (or other judicial process) requiring the payment of money by Landlord in the event of any default by Landlord hereunder, and no other property or assets of Landlord or its partners or principals, disclosed or undisclosed, shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this Lease.

29.4 Force Majeure

The obligations of Tenant hereunder shall in no way be affected, impaired or excused, nor shall Landlord have any liability whatsoever to Tenant, because: Landlord is unable to fulfill, or is delayed in fulfilling, any of its obligations under this Lease by reason of strike, other labor trouble, governmental preemption of priorities or other controls in connection with a national or other public emergency or shortages of fuel, supplies or labor resulting therefrom, or any other cause, whether similar or dissimilar, beyond Landlord’s reasonable control; or of any failure or defect in the supply, quantity or character of electricity, water or other utilities furnished to the Premises, by reason of any requirement, act or omission of the public utility or others serving the Building with electric energy, oil, gas or water, or for any other reason whether similar or dissimilar, beyond Landlord’s reasonable control.

29.5 Effect of Failure to Consent

If Tenant shall request Landlord’s consent and Landlord shall fail or refuse to give such consent, Tenant shall not be entitled to any damages for any withholding by Landlord of its consent, it being intended that Tenant’s sole remedy shall be an action for specific performance or injunction, and that such remedy shall be available only in those cases where Landlord has expressly agreed in writing not unreasonably to withhold its consent or where as a matter of law Landlord may not unreasonably withhold its consent.

29.6 Rules and Regulations

Tenant and its employees and agents shall faithfully observe and comply with the rules and regulations attached to this Lease as Exhibit E and such changes therein as Landlord may from time to time hereafter make and give notice of to Tenant (the “Rules and Regulations”). Landlord shall not be liable to Tenant for violation of the Rules and Regulations by any other tenant or its employees, agents, invitees or licensees.

29.7 Tenant Holdover

If, without objection by Landlord, Tenant fails to vacate the Premises after the Expiration Date of this Lease, or any earlier termination hereof, Tenant shall at the election of Landlord become a tenant from month to month upon the terms of this Lease; provided, however that Base Rent shall be adjusted beginning on the first day after the Expiration Date to be the equal to 110% of the Base Rent in effect at the expiration of the Lease for the first two (2) months and 200% of the Base Rent in effect at the expiration of the Lease thereafter. Notwithstanding anything contained herein to the contrary, Tenant shall be liable to Landlord for any and all damages caused by such failure to vacate the Premises after the Expiration Date of this Lease or any earlier termination hereof, including but not limited to incidental and consequential damages to Landlord.

29.8 Tenant Representations

If Tenant is a corporation or other entity, each person executing this Lease on behalf of Tenant hereby covenants and warrants that Tenant is duly formed and validly existing under the laws of its state of formation; Tenant has full right and authority to enter into this Lease and to perform all Tenant’s obligations hereunder; and each person (and both of the persons if more than one signs) signing this Lease on behalf of Tenant is duly and validly authorized to do so.

29.9 Non-Waiver

No provision of this Lease shall be deemed to have been waived by Landlord unless such waiver is in writing signed by Landlord. Landlord’s waiver of a breach of any term or condition of this Lease shall not be deemed a waiver of any subsequent breach. Acceptance of any Rents or other payments shall not be deemed a waiver of such breach.

29.10 Square Footage Calculations Approximate

The parties acknowledge and agree that any calculations of square footage in the Premises and in the Project are approximations. No recalculation of square footage shall affect the obligation of Tenant under this Lease including, without limitation, the amount of Base Rent payable by Tenant or the amount of Tenant’s Proportionate Share of Operating Expenses or the amount of Tenant’s Proportionate Share of Taxes.

29.11 Time

Time is of the essence of this Lease.

29.12 Late Fees

Tenant acknowledges that late payment by Tenant to Landlord of any Rent due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs may include, without limitation, processing and accounting charges and late charges which may be imposed on Landlord under the terms of any Mortgage. Accordingly, if any Rent payment is not received by Landlord within five days after it is due, Tenant shall pay to Landlord a late charge equal to ten percent (10%) of the overdue amount. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs incurred by Landlord by reason of the late payment by Tenant. Acceptance of any late charge by Landlord shall in no event constitute a waiver of Tenant’s default with respect to the overdue amount in question, nor prevent Landlord from exercising any of the other rights and remedies granted hereunder.

29.13 Attorneys’ Fees

In the event a suit, action, arbitration, or other proceeding of any nature whatsoever, including without limitation any proceeding under the U.S. Bankruptcy Code, is instituted, or the services of an attorney are retained, to interpret or enforce any provision of this Lease or with respect to any dispute relating to this Lease, the prevailing ~~or non defaulting~~ party shall be entitled to recover from the losing ~~or defaulting~~ party its attorneys’, paralegals’, accountants’, and other experts’ fees and all other fees, costs, and expenses actually incurred and reasonably necessary in connection therewith. In the event of suit, action, arbitration, or other proceeding, the amount thereof shall be determined by the judge or arbitrator, shall include fees and expenses incurred on any appeal or review, and shall be in addition to all other amounts provided by law.

29.14 Quiet Enjoyment

So long as Tenant pays all Rents and complies with all of the terms and conditions of this Lease, Tenant shall peaceably and quietly have, hold and enjoy the Premises. This covenant shall be binding upon the subsequent successors in interest of Landlord’s interest in this Lease.

29.15 Severability

If any portion of this Lease is held to be illegal, invalid or unenforceable under present or future law effective during the term of this Lease, the remainder of this Lease shall not be affected thereby.

ADDENDUM TO THE LEASE DATED JUNE 1, 2005 BY AND BETWEEN
SUNSET CENTER, LLC, AN OREGON LIMITED LIABILITY COMPANY, LANDLORD
AND MATHSTAR, A MINNESOTA CORPORATION, TENANT

29.17 OPTION TO EXPAND.

So long as Tenant is not then in default of the Lease beyond any applicable cure periods, Tenant shall have a one-time option to expand the Premises (the “Second Floor Expansion Option”) by adding approximately 2,072 rentable square feet located on the second floor of the Building as outlined on the attached Exhibit A-1 ((the “Second Floor Expansion Option”), in accordance with the terms of this Section 29.17. If Tenant wishes to exercise the Second Floor Expansion Option, Tenant shall do so by giving Landlord written notice of its exercise of the Second Floor Expansion Option (the “Second Floor Expansion Notice”) no later than on June 30, 2006. If Tenant does not give Landlord a written notice exercising Tenant’s Second Floor Expansion Option, then the Option shall terminate and shall be of no further force or effect.

If Tenant gives Landlord written notice of its exercise of the Second Floor Expansion Option on or before June 30, 2006, then, effective on the earlier of (a) the date on which tenant improvements in the Second Floor Expansion Space are substantially completed or (b) September 1, 2006 (the “Second Floor Expansion Space Commencement Date”), the Second Floor Expansion Space shall be added to the Premises. The annual Base Rent for the Second Floor Expansion Space (the “Second Floor Expansion Space Base Rent”) shall equal the rate per square foot at the time of the Second Floor Expansion Space Commencement Date, as set forth in the Summary of Fundamental Provisions, Item #5 of this Lease, multiplied by 2,072’, and the Second Floor Expansion Space Base Rent shall increase as set forth in the Summary of Fundamental Provisions, Item #5 of the Lease. The tenant improvement allowance to be provided by Landlord for the Second Floor Expansion Space shall equal $23.86 per rentable square foot.

Effective on the Second Floor Expansion Space Commencement Date, the following shall occur: (a) the Second Floor Expansion Space shall be added to the Premises for the remainder of the Term of the Lease, (b) Base Rent for the Premises shall be increased by an amount equal to the Second Floor Base Rent determined as provided in this Section 29.17, and (c) Tenant’s Proportionate Share of Operating Expenses shall increase proportionately based on the increase in square footage in the Premises. Subject to the tenant improvement allowance to be provided by Landlord and Landlord’s obligations regarding common areas described above in this Section 29.17, Tenant shall lease the Second Floor Expansion Space in its “as-is” condition as of the Second Floor Expansion Space Commencement Date. The terms of the work agreement attached as Exhibit C to this Amendment shall apply to the improvements to the Second Floor Expansion Space and the use of such tenant improvement allowance as if the Second Floor Expansion Space were the original Premises leased under this Lease.

29.18 RIGHT OF FIRST REFUSAL.

During the first eighteen (18) months of the Lease, in the event a third party is interested in space on the second floor, Landlord agrees to give Tenant prior written notice. Tenant shall have seventy-two (72) hours to respond to the notice and to negotiate a lease satisfactory to Landlord, or Landlord may lease the area to the third party and Tenant shall have no further rights to this space. The same terms and conditions shall apply to said expansion space including, but not limited to, the base rental rate and an improvement allowance equal to $.46 per foot for each month remaining in the lease term effective with the addition of the additional space to the leased Premises. This Right of First Refusal shall expire on December 31, 2006.

29.19 OPTION TO TERMINATION.

Provided Tenant is not in default, Tenant shall have the option to terminate the Lease effective December 31, 2008 by giving Landlord one hundred-eighty (180) days prior written notice. Upon said termination, Tenant shall be required to pay Landlord the unamortized balance of the cost of tenant improvements and all leasing commissions.
