2. PREMISES.

(A) PREMISES. Landlord does hereby lease to Tenant, upon the terms and conditions set forth herein, the premises described in Section 1(d) and shown on Exhibit A attached hereto (the "Premises"), within the Building described in Section 1(e) and in Section 4(a) below and depicted on Exhibit B hereto (the "Building"), which Building shall be located at 333 Elliott Avenue West, Seattle, Washington 98119 on the real property described as follows (the "Property"):

Lots 1, 2, 3, 4, 5, and 6 in Block 160 of Seattle Tide Lands, according to the official maps on file in the office of the Commission of public lands in Olympia, Washington.

Except any portion thereof lying within the railroad right of way.

Upon completion of the Tenant Improvements to the Premises, Landlord shall cause the rentable square footage of the Premises to be measured by Landlord's architect using the BOMA American National Standard Institute Publication, ANSI Z65.1-1996 Standards (the "Rentable Square Footage"), to determine the Building Rentable Area, which measurement shall govern with respect to the Premises Area of Section 1(d). Tenant shall have the right to have a Washington-licensed surveyor approved by Landlord and jointly responsible to Landlord and Tenant verify the Premises Rentable Square Footage determined by Landlord's Architect, if it does so within twenty (20) days after receipt of the notice from Landlord's Architect. If based on such verification Tenant disagrees with the Rentable

-3-

Square Footage determined by Landlord's Architect it shall advise Landlord and its Architect of the deviation within ten (10) days thereafter or be deemed to have accepted Landlord's Architect's determination. If Tenant gives a timely notification of disagreement, then the parties shall jointly select a Washington-licensed surveyor or architect to review the calculations of Landlord's architect and the Tenant selected surveyor and make the determination of Premises Rentable Square Footage, which determination shall be final and binding on the parties.

(B) COMMON AREAS. As used in this Lease, "Common Areas" shall mean all portions of the Building and Property leased but not demised to specific tenants. During the term of this Lease, Tenant and its licensees, invitees, customers and employees shall have the exclusive right to use the Common Areas, including all parking areas, landscaped areas, entrances, lobbies, elevators, stairs, corridors, and public restrooms, and shall have exclusive control and management of the same.

3. TERM.

(A) INITIAL TERM. The Lease Commencement Date shall occur on the latter of the ninetieth (90th) day after the Delivery Date or upon Substantial Completion, as both terms are hereinafter defined, and shall expire on the last day of the one hundred twentieth (120th) full calendar month after the Lease Commencement Date (the "Initial Term").

(B) EARLY POSSESSION. Commencing on the Effective Date, Tenant and Tenant's contractors shall have the non-exclusive right to possess the Premises seven days per week and twenty-four hours per day (the "Early Possession Period") for the purpose of the installation of Tenant's improvements, furniture, fixtures and equipment and completion of Tenant's Work (as defined in the Tenant Work Letter attached hereto as Exhibit C), and to perform such other activities in order to permit and facilitate Tenant's ability to fully occupy and conduct its business on all portions of the Premises as of the Lease Commencement Date. During the Early Possession Period, Tenant shall not be charged Base Monthly Rent, parking charges for stalls located in the Parking Garage or in surface parking lots on the Property, or operating expense charges. Tenant shall coordinate Tenant's Work move-in activities with the contractors working on the site so as not to impede Landlord's Work and the final completion of the Shell and Core Improvements, including punch list type activities. Tenant shall be responsible for the removal and disposal of Tenant's furniture and fixture vendor's cartons and trash.

(C) RENEWAL. Provided that Tenant is not then in material default under the terms of this Lease, Tenant shall have the option(s) to renew this Lease for two (2) additional terms of five (5) years each or, if Tenant so elects, for one (1) additional term of ten (10) years (the "Renewal Terms"). If Tenant elects to renew this Lease, Tenant shall notify Landlord in writing of its intent to exercise such renewal option(s) no later than twelve (12) months prior to the expiration of the then existing Lease term; in the event Tenant exercises its right to initially renew for one (1) additional five (5) year Renewal Term (rather than an additional term of ten (10) years), Tenant shall notify Landlord no later than twelve (12) months prior to the expiration of the first five (5) year Renewal Term if Tenant elects to renew for an additional five (5) year Renewal Term. All provisions of this Lease shall continue in full force and effect during any Renewal Term, except Base Monthly Rent for the Renewal Term shall be at the then fair market rate (as determined based on the following criteria) for comparable space in a comparable Seattle location taking into account and making appropriate modifications for concessions and costs, such as Tenant improvement allowances, free or

-4-

reduced rent periods, construction periods during which rent is not payable and the like, which would be incident to a new lease but that are avoided by Landlord by virtue of the extension of the term of this Lease. If Landlord and Tenant are unable to agree as to the fair market rent within sixty (60) days following Tenant's notice to Landlord of its intent to renew the Lease, fair market rent shall then be determined by appraisal as follows:

Within ten (10) days after expiration of the sixty (60) day period, Landlord and Tenant shall give notice to each other stating the name and address of an impartial person to act as appraiser. Each party's appraiser shall be a licensed commercial real estate broker doing business in Seattle having not less than ten years of active experience as a commercial real estate broker in Seattle, or may be an MAI appraiser with commercial property experience in the Seattle area. The named appraisers shall, together, determine the fair market rent as of the commencement of the particular Renewal Term and according to the standards provided for above herein within thirty (30) days after their appointment. If the two appraisers shall fail to agree upon fair market rent within thirty (30) days of their appointments, and the difference in their conclusions about fair market rent is ten percent (10%) or less of the lower of the two determinations, then fair market rent shall be the average of the two determinations. If the two appraisers fail to agree on fair market rent and the difference between the two determinations exceeds ten percent (10%) of the lower of the two determinations, then the appraisers shall appoint a third appraiser similarly impartial and qualified to determine fair market rent. Such third expert shall determine the market rent within thirty
(30) day of his/her appointment and the average of the determinations of the two closest experts shall be final, conclusive and binding on Landlord and Tenant. Landlord and Tenant shall then execute and deliver an amendment to this Lease confirming Base Monthly Rent to be applicable during the particular Renewal Term. Landlord and Tenant shall each pay the fees of any appraiser appointed by Landlord and Tenant respectively, and Landlord and Tenant shall each pay one-half of the fees of any third appraiser appointed pursuant to the provisions of this paragraph.

(D) EARLY TERMINATION. Without limiting any other provisions set forth herein, in the event Tenant vacates its offices in the 401 Elliott Avenue Building, Tenant shall have the one-time right and option to cancel and terminate this Lease effective as of the expiration of the fifth (5th) year of the Initial Term by giving Landlord no less than twelve (12) months prior written notice and paying to Landlord an Early Termination Fee calculated as follows: (i) the unamortized portion of the Tenant Allowance, (ii) the unamortized portion of Pre-Paid Rent for months 12, 24 and 48 of the Initial Term, paid on behalf of Landlord for a portion of the Leasing Fee, and (iii) the unamortized portion of the Rent that would have been payable by Tenant to Landlord on Space Pocket Areas (defined in Section 5(d) below), had no portion of the Premises been designated as a Space Pocket Areas pursuant to Section 5(d), all amortized on a straight-line basis with interest at 8% per annum over the Initial Term, such payment to be made to Landlord no later than one hundred twenty (120) days prior to the effective Lease termination date; provided, however, that the Early Termination Fee shall be reduced by the Base Monthly Rent otherwise due, and pre-paid, for the said 72nd month of the Initial Term.

4. DESIGN, CONSTRUCTION AND COMPLETION.

(A) DESIGN. Landlord shall cause the Building to be designed, constructed and completed according to the design criteria, specifications and construction standards described on Exhibit D ("Building Shell and Core Outline Specifications"), the architectural, structural and mechanical plans referred to on Exhibit E (the "Plans", which plans are incorporated

-5-

herein as if fully set forth) and the floor plans depicted on Exhibit A, each of which Exhibits is attached hereto and incorporated herein by this reference, together with the other terms and conditions of this Lease. Landlord shall provide Tenant true and correct copies of all plans and specifications, and all material modifications thereto as they occur.

(B) CONSTRUCTION. The contract(s) for construction of the Building shall impose schedules and deadlines on Landlord's contractor(s) so as to assure timely Substantial Completion and a timely Delivery Date. Whenever the construction schedule is revised, Landlord shall notify Tenant and promptly provide Tenant with a true and correct copy of the revised schedule.

(C) PROGRESS. Landlord shall instruct its architect to issue a certificate to Tenant at such times as the Building is at seventy-five percent (75%) and one hundred percent (100%) of Substantial Completion, stating that the completed work fully complies with (i) the plans approved by all necessary governmental agencies and (ii) Exhibits C and D attached hereto. To the extent that City of Seattle inspectors or inspectors for Landlord's construction lender also provide progress certifications, copies of the same shall be provided to Tenant promptly after being received by Landlord.

(D) DELIVERY AND COMPLETION. Landlord shall achieve Substantial Completion of the Building and the Premises in accordance with the permitted plans and specifications, and terms of the Exhibits hereto, by no later than January 31, 2008. For purposes of this Lease, "Substantial Completion" means issuance of the final City of Seattle shell and core Certificate of Occupancy for the Building and with respect to each floor of the Building and the parking garage. For purposes of this Lease, "Delivery Date" shall mean the date on which:

(1) The Building is fully enclosed and water tight, including the roof and permanent exterior walls and windows;

(2) Power and lighting and electrical service are available as described in Exhibit D to the Lease for distribution by Tenant; and

(3) There shall be evidence reasonably satisfactory to Tenant that:

(i) The balance of the Landlord Work can be completed prior to Lease Commencement; and

(ii) The Tenant's contractor is able to proceed efficiently with the Tenant Work, subject to a requirement of reasonable coordination and cooperation with the Landlord's shell and core contractor.

(E) LATE DELIVERY. For each day that Delivery Date is delayed past November 1, 2007, Tenant shall be entitled to a credit as provided below against its Rent otherwise first falling due (exclusive of pre-paid rent) under this Lease during the Initial Term, except to the extent any such delay was caused by a Force Majuere Event. A "Force Majeure Event" means only acts of God, strikes, lockouts, labor troubles, inability to procure materials despite commercially reasonable efforts to do so, discovery of archeologically significant artifacts which halt construction, reasonably unforeseen sub-surface conditions materially delaying project excavation, acts of civil or military authorities, fires, floods and earthquakes. Landlord shall notify Tenant in writing of each delay Landlord contends was caused by a Force Majeure Event within ten (10) business days of its occurrence, describing the impact on the then current construction schedule.

-6-

More specifically:

(1) In the event the Delivery Date is delayed for up to sixty (60) days past November 1, 2007, then Tenant shall be entitled to rent abatement in an amount equal to two (2) days pro-rata Base Monthly Rent for each one (1) day of such delay;

(2) In the event the Delivery Date is delayed for up to an additional one hundred twenty (120) days after December 30, 2007, then Tenant shall be entitled to rent abatement in an amount equal to three (3) days pro-rata Base Monthly Rent for each one (1) day of such additional delay; and

(3) Notwithstanding the foregoing, in the event the Delivery Date is delayed past April 29, 2008, or in the event at any time the construction schedule prepared by Landlord's prime contractor or certified by Landlord's architect reasonably indicates the Delivery Date will occur after April 29, 2008, then in either event Tenant may terminate this Lease after thirty (30) days written notice to the Landlord unless the Delivery Date is attained during such thirty (30) day period.

(F) LATE COMPLETION. For each day that Substantial Completion is delayed past January 31, 2008, Tenant shall be entitled to a credit as provided below against its Rent otherwise first falling due (exclusive of pre-paid rent) under this Lease during the Initial Term, except to the extent any such delay was caused by a Force Majuere Event. A "Force Majeure Event" means only acts of God, strikes, lockouts, labor troubles, inability to procure materials despite commercially reasonable efforts to do so, discovery of archeologically significant artifacts which halt construction, reasonably unforeseen sub-surface conditions materially delaying project excavation, acts of civil or military authorities, fires, floods and earthquakes. Landlord shall notify Tenant in writing of each delay Landlord contends was caused by a Force Majeure Event within ten (10) business days of its occurrence, describing the impact on the then current construction schedule.

More specifically:

(1) In the event Substantial Completion is delayed for up to sixty
(60) days past January 31, 2008, then Tenant shall be entitled to rent abatement in an amount equal to two (2) days pro-rata Base Monthly Rent for each one (1) day of such delay;

(2) In the event Substantial Completion is delayed for up to an additional one hundred twenty (120) days after March 31, 2008, then Tenant shall be entitled to rent abatement in an amount equal to three (3) days pro-rata Base Monthly Rent for each one
(1) day of such additional delay; and

(3) Notwithstanding the foregoing, in the event Substantial Completion is delayed past July 29, 2008, or in the event at any time the construction schedule prepared by Landlord's prime contractor or certified by Landlord's architect reasonably indicates Substantial Completion will occur after July 29, 2008, then in either event Tenant may terminate this Lease after thirty
(30) days written notice to the Landlord unless Substantial Completion is attained during such thirty (30) day period.

5. RENT.

(A) BASE MONTHLY RENT. Subject to Section 5(d), Tenant shall pay Landlord monthly base rent in the initial amount set forth in Section 1 which shall be payable monthly in advance on the

-7-

first day of each and every calendar month ("Base Monthly Rent") beginning on the Lease Commencement Date until the expiration or earlier termination of this Lease.

(B) PRE-PAID RENT. As otherwise provided in Section 37 below herein, upon Broker's certification to Landlord that the Leasing Fee has been paid, Tenant shall be deemed to have paid in full all Base Monthly Rent otherwise due hereunder applicable to months twelve (12), twenty-four
(24), forty-eight (48) and seventy-two (72) of the Initial Term hereof.

(C) RENT ADJUSTMENT. Base Monthly Rent shall be increased on each anniversary of the Lease Commencement Date by an amount equal to $1.00 per rentable square foot per annum as set forth in Section 1(j).

(D) RENT ABATEMENT. Notwithstanding anything to the contrary herein, within thirty (30) days after commencing to conduct business in the Building, Tenant shall have the option to designate up to 20,000 RSF as a space pocket area, which area may be comprised of space located in various areas and floors of the Building as Tenant may select (collectively, the "Space Pocket Area"), thereafter, space pockets may not be switched or otherwise reconfigured. For each of the eighteen
(18) months immediately following the Lease Commencement Date, Tenant shall not pay Rent on the Space Pocket Area as long as the Space Pocket Area remains unoccupied by Tenant. Tenant shall promptly notify Landlord of its use and occupancy of any portion of the Space Pocket Area, and shall commence paying Rent on each portion of the Space Pocket Area at such time as Tenant occupies such area. Occupancy of any portion of the Space Pocket Area shall mean the date on which Tenant first has an employee actually working in such area.

(E) RENT WITHOUT OFFSET AND LATE CHARGE. All Base Monthly Rent shall be paid by Tenant to Landlord without prior notice or demand in advance on the first day of every calendar month, at the address shown in
Section 1(c), or such other place as Landlord may designate in writing from time to time. Whether or not so designated, all other sums due from Tenant under this Lease shall constitute Additional Rent, payable without prior notice or demand when specified in this Lease, but if not specified, then within thirty (30) days of demand, during which time the parties will work to resolve any good faith disagreements on the amount due. All Rent shall be paid without any deduction or offset whatsoever except as otherwise specifically provided herein. All Rent shall be paid in lawful currency of the United States of America. Proration of Rent due for any partial month shall be calculated by dividing the number of days in the month for which Rent is due by the actual number of days in that month and multiplying by the applicable monthly rate. Tenant acknowledges that late payment by Tenant to Landlord of any Rent, Additional Rent or other sums due under this Lease will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such cost being extremely difficult and impracticable to ascertain. Such costs include, without limitation, processing and accounting charges and late charges that may be imposed on Landlord by the terms of any encumbrance or note secured by the Premises. Therefore, if any Rent or other sum due from Tenant is not received within ten (10) business days of the date due, Tenant shall pay to Landlord a sum equal to five percent (5%) of such overdue payment. Landlord and Tenant hereby agree that such late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of any such late payment and that the late charge is in addition to any and all remedies available to the Landlord and that the assessment and/or collection of the late charge shall not be deemed a waiver of any other default.

-8-

6. USE AND ACCESS.

(A) TENANT'S USE. Tenant may use and occupy the Premises for any lawful commercial purpose. Tenant shall have access to the Premises and to the parking 24 hours per day, 7 days per week, 365 days per year, including all holidays. Tenant shall promptly comply with all laws, ordinances, orders and regulations affecting the Premises and the Building, including, without limitation, any rules and regulations that may be attached to this Lease and to any reasonable modifications to these rules and regulations as Landlord may adopt from time to time. Tenant will not knowingly use or permit to be used in said Premises anything that will materially increase the rate of insurance on said Building or any part thereof, nor anything that may be dangerous to life or limb; nor in any manner deface or injure said Building or any part thereof; nor overload any floor or part thereof; nor permit any unreasonably objectionable noise or odor to escape or to be emitted from said Premises, or do anything or permit anything to be done upon said Premises in any way tending to create a nuisance or to disturb any other tenant or occupant of any part of said Building. Tenant, at Tenant's expense, will comply with all health, fire and police regulations respecting said Premises.

(B) LANDLORD ACCESS. Landlord, its engineer or other agents may retain a pass key to said Premises to enable Landlord to examine the Premises from time to time with reference to any emergency or to the general maintenance of said Premises. In recognition that Tenant will be conducting business that may involve matters of a non-public or confidential nature, if no emergency exists, Landlord shall provide Tenant at least 24 hours notice of any entry into the Premises, and Tenant shall have the right to have a party present during any such entry by Landlord, Landlord's engineer or any other agents.

(C) LANDLORD ALTERATIONS. Tenant acknowledges that Landlord may from time to time, at its reasonable discretion, make such modifications, alterations, deletions or improvements to the Building as Landlord may deem necessary or desirable, without compensation or notice to Tenant as long as such modifications, alterations, deletions or improvements do not materially alter Tenant's use of its Premises.

7. HAZARDOUS SUBSTANCES. Landlord hereby covenants and warrants to Tenant that the Premises will not contain any Hazardous Material, or if such material does exist, it exists in compliance with all applicable federal, state or local law, and agrees that if during the term of the Lease Hazardous Material not introduced by Tenant is discovered within the Premises, or any state, federal or local governmental authority or agency having jurisdiction requires the removal of any Hazardous Material, Landlord shall at Landlord's expense remove, encapsulate or take other accepted abatement measures with respect to such Hazardous Material in compliance with or as required by all applicable laws, rules and regulations of local, state and federal governmental authorities. Landlord shall defend, indemnify and save Tenant harmless from and against any injuries, claims, accidents, damages, liabilities and expenses (including reasonable counsel fees) arising out of any breach of the foregoing representation and warranty of Landlord. The provisions of this paragraph shall survive the expiration or termination of the Lease.

For purposes of this Section 7, Hazardous Material shall include flammables, explosives, radioactive materials, hazardous wastes or materials, toxic wastes or materials, or other similar substances, petroleum products or derivatives thereof or any substance subject to regulation by or under any federal, state and local laws and ordinances relating to the protection of the environment or the keeping, use or disposition of environmentally hazardous materials, substances, or wastes,

-9-

presently in effect or hereafter adopted, all amendments to any of them, and all rules and regulations issued pursuant to any of such laws or ordinances.

The parties anticipate that Landlord may be required to conduct certain environmental work at, about or beneath the Building following completion of the Building and commencement of the Initial Term, which may involve monitoring and pumping sub-surface water. Any and all such work shall be the entire responsibility of Landlord to be conducted at Landlord's sole cost and risk including additional water/sewer charges for such water, and without interference to Tenant's quiet enjoyment of the Premises.

8. BUILDING SERVICES, COSTS AND REPAIRS. This is a "triple net", NNN Lease. During the term of this Lease, Tenant shall be responsible for payment of all costs and expenses incurred for electric light and power, heat, air conditioning, elevators, water, sewer, janitorial services, parking services, all building maintenance contracts (except those which are Landlord's responsibility as provided in Section 12 below), recycling and trash removal, window washing, security, landscaping, real estate taxes and insurance, and all other services to the Building. Tenant shall contract directly with utility and service providers for the provision and payment of all such utilities and other services. Landlord shall be fully responsible for the cost of, and shall promptly and regularly perform, all repairs and maintenance to the roof, exterior walls and foundation. To the extent Tenant's repair and maintenance obligations hereunder relate to work performed for or goods supplied to Landlord, Landlord shall assign to Tenant all applicable warranties and service contracts. In the event this Lease is hereafter amended to contract the scope of the Premises, such amendment shall then also provide for pro-ration or separate metering of Tenant's utility/operating/repair costs, taxes to be paid by Tenant and insurance premiums to be paid by Tenant to reflect Tenant's reduced occupancy.

9. TAXES AND OTHER CHARGES.

(A) OBLIGATION FOR PAYMENT. Tenant shall pay, satisfy and discharge as the same become due and payable and prior to delinquency all ad valorem real and personal property taxes and assessments and any other taxes or charges levied or imposed upon or against Tenant's proportionate share of the real estate on which the Building is to be situated and/or any improvements now or hereafter made or constructed upon the real estate on which the Building is to be situated (the "Improvements") during the term of this Lease (collectively, "Taxes"). If any Taxes are levied against Landlord or Landlord's property and if Landlord elects to pay the same or if the assessed value of Landlord's property is increased by inclusion of personal property and trade fixtures placed by Tenant in the Premises and Landlord elects to pay the Taxes based on such increase, Tenant shall pay to Landlord upon demand that part of such Taxes for which Tenant is primarily liable hereunder.

(B) TAXES PAYABLE IN INSTALLMENTS. If, by law, any Taxes may, at the option of the taxpayer, be paid in installments (whether or not interest accrues on the unpaid balance of such tax), Tenant may pay such Taxes (and any accrued interest on the unpaid balance of such Taxes) in installments, as they become due during the Term of this Lease.

(C) PRORATION OF TAXES FOR PERIOD OTHER THAN TERM. Any Taxes, including Taxes which have been converted into installment payments, relating to a part of a fiscal period of the taxing authority which has been included within the term and a part of which has been included in a period of time prior to the commencement or after the end of the term, shall, whether or not the Taxes are assessed, levied, confirmed, imposed upon or in respect of,

-10-

or become a lien upon the Premises, or become payable during the term, be adjusted between Landlord and Tenant as of the commencement or end of the term, so that Tenant will only pay that portion of such Taxes applicable to the term, and Landlord will pay the remainder.

(D) RIGHT TO CONTEST TAXES. Tenant shall have the right to contest the amount or validity, in whole or in part, of any Taxes by appropriate proceedings diligently conducted in good faith, only after paying the same or posting such security as Landlord may reasonably require in order to protect the Premises against loss or forfeiture. Upon the termination of any such proceedings, Tenant will pay the amount of such Taxes or part of such Taxes as finally determined to be due and payable, the payment of which may have been deferred during the prosecution of such proceedings, together with any costs, fees, interest, penalties, or other related liabilities. Landlord will not be required to join in any such contest or proceedings unless the provisions of any law or regulations then in effect require that such proceedings be brought by or in the name of Landlord. In that event, Landlord will join in such proceedings or permit them to be brought in its name; however, Landlord will not be subject to any liability for the payment of any costs or expenses in connection with any such contest or proceedings, and Tenant shall indemnify Landlord against and save Landlord harmless from any such costs and expenses.

(E) ADDITIONAL TAXES OR ASSESSMENTS. Should there presently be in effect or should there be enacted during the term of this Lease, any law, statute or ordinance levying any assessments or any tax upon the Premises other than federal or state income taxes, Tenant shall reimburse Landlord for Tenant's proportionate share of said taxes or assessments at the same time as rental payments.

10. SIGNAGE. Tenant shall have the exclusive right to name the Building the "F5 Building" or such other appropriate name as Tenant may select. Tenant shall have the exclusive right, at Tenant's expense, to place its corporate logo or other identifying signage on the exterior of the Building, the size, location and design of which are depicted on Exhibit B hereto, or as otherwise reasonably approved by Landlord; provided, however, that Landlord hereby approves exterior signage consistent with the size, scope and nature of that currently in place at the 401 Elliott Building. No other sign, picture, advertising or notice shall be displayed, inscribed, painted or affixed to any of the glass or exterior of the Building without the prior approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed.

11. BUILDING PARKING GARAGE.

(A) GRANT OF EXCLUSIVE RIGHT. Landlord grants to Tenant and Tenant's customers, suppliers, employees and invitees, the exclusive right to use the Building Garage and the surface parking located on the Property. The Building Garage shall contain not less than one hundred twenty-three (123) parking stalls, there shall be not less than twenty-three (23) surface lot parking stalls on the Property, and Landlord shall provide to Tenant not less than one hundred (100) parking stalls at lots located within a two and one-half block radius of the Property (the "Off-Site Parking"). The initial charge will be $125.00 per month per stall for spaces within the Building Garage and $100.00 per month for spaces exterior to the Building Garage. In the event Landlord sells the Building, Landlord will no longer have an obligation to provide the Off-Site Parking.

(B) CHARGES. The initial monthly charge for the parking to be provided to Tenant by Landlord shall be the amounts set forth in Section 1(i) of the Lease. Such rate shall be in

-11-

effect upon the Commencement Date of the Lease, subject to adjustment during each year of the Lease term based upon comparable parking rates for similar Buildings in the Lower Queen Anne area (reflecting any applicable federal, state and local taxes and levies); provided, however, in no event shall the rates set forth in Section 1(i) be increased during the initial twelve (12) months of the Lease term. Tenant's monthly parking charge for all parking permits and the charges for all validated parking, if any, shall be billed to Tenant and shall be due as Additional Rent within ten (10) days after such billing.

12. MAINTENANCE. Landlord shall maintain and repair, in good condition, the structural parts of the Premises and the Building, which shall include the foundations, bearing and exterior walls (excluding glass), subflooring and roof (excluding skylights), the electrical, plumbing and sewerage systems outside the Building, gutters and downspouts (excluding cleaning, which shall be Tenant's responsibility) on the Building. Except as provided above, Tenant shall maintain and repair the Premises in good condition, including, without limitation, maintaining and repairing all walls, storefronts, floors, ceilings, HVAC systems, interior and exterior doors, exterior and interior windows and fixtures and interior plumbing. Upon expiration or termination of this Lease, Tenant shall surrender the Premises to Landlord in the same condition as existed on the Lease Commencement Date, except for reasonable wear and tear or damage caused by fire or other casualty. Except as provided below, Tenant shall have no obligation to remove Tenant's Work from the Premises at the time Tenant surrenders possession of the Premises to Landlord.

13. ALTERATIONS. Tenant shall have the right to make alterations or additions to the Premises, or construct additional improvements on the Premises, subject to the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed; provided, however, that Landlord's prior written consent will not be necessary for any alteration, addition, or improvement of a cosmetic and non-structural nature. All work shall be made with due diligence, in a good and workmanlike manner and in compliance with all laws, ordinances, orders, rules, regulations, certificates of occupancy, or other governmental requirements, and provided Tenant shall provide Landlord with thirty (30) days advance notice before commencing such work, excepting the cosmetic work. Title to all improvements constructed or installed by Tenant shall be and remain vested in Tenant during the term of this Lease. All alterations, additions, fixtures, and improvements, whether temporary or permanent in character, made to the Premises by Tenant, will immediately vest in Landlord at the end of the Term of this Lease and will remain on the Premises without compensation to Tenant. Notwithstanding anything to the contrary in this section, all equipment, shelves, bins, machinery and trade fixtures installed by Tenant may be removed by Tenant prior to the termination of this Lease if Tenant so elects, and shall be removed by the date of termination of this Lease or upon earlier vacating of the Premises if required by Landlord; upon any such removal, Tenant shall repair the portion of the Premises from which such equipment, shelves, bins, machinery or trade fixtures were removed. Upon Lease expiration, Tenant shall, upon Landlord's request, remove its cabling from the Premises and the Building. All such removals and restoration shall be accomplished in good workmanlike manner so as not to damage the primary structure or structural qualities of the Buildings and other improvements situated on the Premises.

14. RELEASE AND INDEMNITY. Either party (each as the "Indemnifying Party") will defend, indemnify and hold harmless the other from any claim, liability or suit including attorney's fees by any person, persons, and/or entity for any injuries or damages occurring in or about the said Premises or on or about the sidewalk, stairs, or thoroughfares adjacent thereto where said damages or injury was caused by the negligence or intentional act of the Indemnifying Party, its agents, employees, servants, customers or clients.

-12-

15. INSURANCE.

(A) CASUALTY INSURANCE. Landlord shall, at Tenant's expense, obtain and keep in force, throughout the Initial Term and any Renewal Term(s) of this Lease, a policy or policies of "all-risk" casualty insurance, insuring the Premises against loss or damage by fire or other casualty (including earthquake and flood), naming Tenant and such other parties as Landlord or Tenant may designate as additional insureds as their interests may appear. The amount of such insurance will be not less than the full replacement value of the Building. Tenant shall be provided with full copies of all policies as revised or supplemented from time to time.

(B) GENERAL LIABILITY INSURANCE. Landlord shall, at Tenant's expense, obtain and keep in force during the Initial Term and all Renewal Term(s) of this Lease, a policy or policies of general liability insurance with a combined single limit of not less than $1,000,000 for injury to or death of any one person, $100,000 for injury to or death of any number of persons in any one occurrence, and $100,000 for damage to property, insuring against any and all liability of Landlord and Tenant including, without limitation, coverage for contractual liability, broad form property damage, host liquor liability, and non-owned automobile liability, with respect to the Premises or arising out of the maintenance, use, or occupancy of the Premises. Such insurance will be separate from any insurance which may be carried by Tenant and will contain a provision that Tenant, as an additional named insured, will be entitled to recover under the policy for any loss, injury, or damage to Tenant, its agents, and employees, or the property of such persons.

(C) PASS-THROUGH PREMIUMS. Tenant shall be responsible for payment of all premiums for insurance provided by Landlord under this section to the extent such premiums are applicable only to the Premises, and shall reimburse Landlord for the same within thirty (30) days after receipt of Landlord's invoice for the same; provided, however, that if Tenant can replace Landlord's insurance provided for herein at a more economical rate to Tenant and otherwise fully consistent with the insurance requirements of this section, Tenant may with the Landlord's approval, which shall not be unreasonably withheld, delayed or conditioned, contract directly for such insurance coverage, with Landlord as an additional named insured, in which case Tenant shall no longer be responsible for reimbursement to Landlord for the cost of any insurance Landlord elects to retain.

(D) OTHER MATTERS. All insurance required in this paragraph and all renewals of it will be issued by companies authorized to transact business in the State of Washington. All insurance policies shall be subject to approval by Landlord and Tenant as to form and substance, shall expressly provide that such policies shall not be canceled or altered without thirty (30) days' prior written notice to Landlord and Tenant and shall, to the extent obtainable, provide that no act or omission of Tenant which would otherwise result in forfeiture or reduction of the insurance will affect or limit the obligation of the insurance company to pay the amount of any loss sustained. Upon issuance each insurance policy, a duplicate or certificate of such policy shall be delivered to Landlord and Tenant. Landlord may satisfy its obligation under this paragraph by appropriate endorsements of its blanket insurance policies.

-13-

(E) MUTUAL WAIVER. Landlord and Tenant waive all rights to recover against each other or against any other Tenant or occupant of the Building, or against the officers, directors, shareholders, partners, joint venturers, employees, agents, customers, invitees or business visitors of each of theirs or of any other Tenant or occupant of the Building, for any loss or damage arising from any cause covered by any insurance required to be carried by each of them pursuant to this section or any other insurance actually carried by each of them to the extent actually covered by any such insurance. Landlord and Tenant will cause their respective insurers to issue appropriate waiver of subrogation endorsements to all policies of insurance carried in connection with the Premises, Improvements or the contents of either of them. Tenant will cause all other occupants of the Premises claiming by, under, or through Tenant to execute and deliver to Landlord a waiver of claims similar to the waiver in this paragraph and to obtain such waiver of subrogation rights endorsements.

16. DESTRUCTION. If during the Term, more than twenty-five percent (25%) of the Premises are destroyed from any cause, or rendered inaccessible or unusable from any cause, Landlord may, in its sole discretion, terminate this Lease by delivery of notice to Tenant within thirty (30) days of such event without compensation to Tenant. If in Landlord's estimation, the Premises cannot be restored within one hundred eighty (180) days following such destruction, then Landlord shall notify Tenant and Tenant may terminate this Lease by delivery of notice to Landlord within thirty (30) days of receipt of Landlord's notice. If neither Landlord nor Tenant terminates this Lease as provided above, then Landlord shall commence to restore the Premises in compliance with then existing laws and shall complete such restoration with due diligence. In such event, this Lease shall remain in full force and effect, but there shall be an abatement of Base Monthly Rent and Tenant's obligation for the payment of expenses under Section 8 above between the date of destruction and the date of completion of restoration, based on the extent to which destruction interferes with Tenant's use of the Premises.

17. CASUALTY; CONDEMNATION.

(A) CASUALTY. In the event the leased Premises or the Building is destroyed or injured by fire, earthquake or other casualty to the extent that they are no longer satisfactory for the conduct of Tenant's business, in whole or in part, then Landlord will engage a registered architect to certify within sixty (60) days after such destruction or injury to Landlord and Tenant the amount of time needed to restore the Building and the Premises to substantially the same condition as existed immediately prior to the casualty. If the time needed to so restore the Building and Premises exceeds twelve (12) months from the date of the casualty, then either the Landlord or Tenant may terminate this Lease by giving the other party such notice of termination within thirty (30) days after the notifying party's receipt of the architect's certificate. If a casualty causes damages to the Building and this Lease is not terminated by either party under the provisions of this section, then Landlord shall diligently rebuild and restore the Building and the Premises. Upon a casualty event, the rent shall be abated equitably on a per diem basis for the portion of the Premises that is unfit for occupancy commencing upon the date of the casualty and ending on the completion of the repair and restoration so as to permit Tenant's full and regular occupancy thereof or the earlier termination of this Lease. During any period of abatement of rent due to casualty or destruction of the Premises, unless this Lease has been terminated, Landlord shall use its best efforts to locate comparable space for Tenant at the fair market rate not to exceed Tenant's rental rate hereunder. Landlord shall not be liable for any consequential damages by reason of inability, after use of its best efforts, to locate alternative space comparable to the Premises. Notwithstanding anything to the contrary in this

-14-

Section 17(a). if the casualty occurs in the last eighteen (18) months of the then current term of the Lease, either Landlord or Tenant may terminate this Lease upon thirty (30) days written notice.

(B) CONDEMNATION. If the whole of the Premises are taken by any public authority under the power of eminent domain, or purchased by the condemnor in lieu thereof, the term of this Lease shall terminate as of the date possession is taken by such public authority. If only a part of the Premises are taken, the Lease shall terminate only as to the portion taken, and shall continue in full force and effect as to the remainder of the Premises, and the Base Monthly Rent shall be reduced proportionately; provided, however, if the remainder of the Premises cannot be made tenantable for the purposes for which Tenant has been using the Premises, or if more than twenty-five percent (25%) of the rentable square footage of the Premises are taken, then either party, by written notice to the other, given at least thirty (30) days prior to the date that possession must be surrendered to the public authority, may terminate this Lease effective as of such surrender of possession. If this Lease is not terminated and the Premises have been damaged as a consequence of a partial taking, Landlord shall restore the Premises continuing under this Lease at Landlord's cost and expense; provided, however, that Landlord shall not be required to repair or restore any injury or damage to the property of Tenant or to make any repairs or restoration of any alterations, additions, fixtures or improvements installed on the Premises, regardless of whether any of such items were initially installed or paid for by Landlord or Tenant.

18. ASSIGNMENT OR SUBLEASE. Tenant will not assign this Lease, or any interest hereunder, or sublet all or any portion of the Premises or permit the use of the Premises by any party other than Tenant and its agents, and this Lease, or any interest hereunder, shall not be assigned by operation of law without Landlord's prior written consent, which shall not be unreasonably withheld, conditioned or delayed, except that this Lease may be assigned and all or any portion of the Premises sublet without Landlord's consent to a wholly owned subsidiary or parent of Tenant, or to the entity with which or into which Tenant may merge, whether or not Tenant is the survivor of such merger, or to the purchaser of substantially all of the assets of Tenant located at the Premises, provided Tenant shall give Landlord written notice of such assignment. A transfer of Tenant's stock shall not be deemed an assignment. In the event such written consent shall be given, no other or subsequent assignment or subletting shall be made without the previous written consent of Landlord, whose consent shall not be unreasonably withheld, conditioned or delayed. In the event the Premises or a portion thereof is sublet (other than in the event of a permitted transfer) rent paid to Tenant in excess of the rent payable hereunder shall be split equally between Landlord and Tenant after all costs are deducted which were incurred by Tenant attributable to subleasing such space.

19. TENANT DEFAULT. If Tenant fails to comply with any obligation set forth in this Lease within thirty (30) days (or five (5) business days for any monetary default) after receipt of notice of such failure, then, Landlord may with or without further notice or demand, at Landlord's option, and without being deemed guilty of trespass and/or without prejudicing any remedy or remedies which might otherwise be used by Landlord for arrearages or preceding breach of covenant or condition of this Lease, enter into and repossess said Premises and expel the Tenant and all those claiming under Tenant. In such event Landlord may eject and remove from the Premises all goods and effects (forcibly if necessary). This Lease if not otherwise terminated may immediately be declared by Landlord as terminated. The termination of this Lease pursuant to this Section 19 shall not relieve Tenant of its obligations to make the payments required herein. In the event this Lease is terminated pursuant to this Section 19, or if Landlord enters the Premises without terminating this Lease and Landlord relets all or a portion of the Premises, Tenant shall be liable to Landlord for all

-15-

reasonable costs of reletting. Tenant shall remain liable for all unpaid rental which has been earned plus late payment charges and any deficiency between the net amounts received following reletting and the gross amounts due from Tenant, or if Landlord elects, Tenant shall be immediately liable for all rent that would be owing to the end of the term, less any rental loss Tenant proves could be reasonably avoided, which amount shall be discounted by the discount rate of the Federal Reserve Bank, situated nearest to the Premises. Waiver by the Landlord of any default, monetary or non-monetary, under this Lease shall not be deemed a waiver of any future default under the Lease. Acceptance of Rent by Landlord after a default shall not be deemed a waiver of any defaults (except the default pertaining to the particular payment accepted) and shall not act as a waiver of the right of Landlord to terminate this Lease as a result of such defaults by an unlawful detainer action or otherwise. Landlord shall promptly and continually pursue all commercially reasonable efforts and means to relet the Premises following a default by Tenant.

20. SUBORDINATION; ESTOPPEL CERTIFICATE. This Lease and all interest and estate of Tenant hereunder is subject to and is hereby subordinated to all present and future mortgages and deeds of trust affecting the Premises or the property of which said Premises are a part; provided, however, that a condition precedent to Tenant's agreement to subordinate this Lease pursuant to this section shall be Tenant's receipt of a non-disturbance agreement duly executed and acknowledged by the mortgagee or beneficiary of any deed of trust, and in recordable form, that in the event of foreclosure sale or deed in lieu of foreclosure, for so long as Tenant is not in default under the terms, covenants and conditions of this Lease, this Lease shall continue in full force and effect as a direct Lease between the Tenant and the lender or other succeeding owner of the Premises. Tenant agrees to execute at no expense to the Landlord, any instrument which may be deemed necessary or desirable by Landlord to further effect the subordination of this Lease to any such mortgage or deed of trust. In the event of a sale or assignment of Landlord's interest in the Premises, or in the event of any proceedings brought for the foreclosure of, or in the event of exercise of the power of sale under any mortgage or deed of trust made by Landlord covering the Premises, Tenant shall attorn to the purchaser and recognize such purchaser as Landlord. Tenant agrees to execute, at no expense to Tenant, an estoppel certificate certifying as to the following matters:

(i) that this Lease is in full force and effect, is binding upon Tenant and that the Lease has not been modified (or stating all modifications to this Lease);

(ii) the date to which Rent has been paid, the dates to which Rent has been paid in advance, and the amount of any security deposit, if any, or prepaid rent;

(iii) the rentable square footage of the Premises;

(iv) that there are no current defaults which with the giving of notice or the passage of time or both would constitute a breach or default under the Lease by Tenant, or to Tenant's knowledge, by Landlord (or specifying any such defaults);

(v) the Base Rent for the remainder of the Lease term, the Commencement Date, and the Expiration Date; and

(vi) such other matters pertaining to the Lease as may be reasonably requested by Landlord or any mortgagee, beneficiary, purchaser or prospective purchaser of the Premises, the Building or any interest therein.

21. TENANT IMPROVEMENTS/ALLOWANCE. Landlord shall provide Tenant with a cash allowance equivalent to $35.00 per rentable square foot or $4,802,035.00 (the "Tenant

-16-

Allowance"). The Tenant Allowance may be used by Tenant for all "hard" and "soft" costs associated with the Tenant's Work, including, without limitation, architect and engineer fees, the fee of a Tenant improvement coordinator, permit and plan costs and fees, paint, carpet, wiring and cabling, communication systems of every nature, construction and other costs Tenant incurs in order to build-out the Premises for Tenant's intended use. Any Tenant cost for Tenant's Work in excess of the Tenant Allowance shall be entirely the responsibility of Tenant; provided, however, that in addition to the Tenant Allowance, Landlord shall pay to Tenant $32,000.00 for Tenant's security system and $50,000.00 for Building lobby improvements, due upon completion of the security system and/or lobby improvements as the case may be. The Tenant's Work and the Tenant Allowance are more fully described in the Tenant Work Letter attached hereto as Exhibit C.

22. FIBER OPTICS. Tenant shall have the right to install satellite dishes, fiber optics and related equipment for Tenant's sole use at Tenant's sole cost, expense and liability, subject to Landlord's approval of the location and method of installation, which shall not be unreasonably withheld or delayed for installations that do not interfere with other electronic installations on the Building. Tenant's rights pursuant to this section shall include the right to make reasonable replacements, upgrades and additions subject to the terms of this section.

23. USE OF THE ROOF FOR BUSINESS PURPOSES. Tenant shall have the right to enter on the roof of the Building from time to time, in accordance with the provisions of this section and with the prior approval of Landlord, for the purpose of installing and maintaining, at Tenant's sole cost and expense, equipment in connection with Tenant's use of the Premises (the "Tenant's Equipment") at locations, designated by Landlord. Tenant shall submit drawings, specifications, and installation data for Tenant's Equipment to Landlord for its approval prior to installation.

Installation of Tenant's Equipment shall be accomplished under the direct supervision of Landlord and in accordance with reasonable rules and regulations prescribed by Landlord. Tenant's Equipment shall be grounded in accordance with Underwriters Laboratories, Inc. requirements.

Tenant shall make no penetration of the Building's roof during installation or removal of Tenant's Equipment without the prior written consent of Landlord. Tenant shall be responsible for the cost of repairing all damages to Landlord's property caused by the installation, operation, repair, or removal of Tenant's Equipment, except to the extent caused by Landlord, its contractors, or employees. Furthermore, in the event Landlord determines that the Building roof must be repaired or resealed as a direct or indirect result of the installation, maintenance, repair, or removal of Tenant's Equipment, except to the extent caused by Landlord, its contractors, or employees, all such repairing and/or resealing shall be performed by Landlord's designated contractor at Tenant's sole cost and expense.

Upon termination of this Lease, Tenant, at its sole cost, shall at the request of Landlord remove Tenant's Equipment from the roof of the Building, subject to the provisions of this section. Removal of Tenant's Equipment shall be done in a manner satisfactory to Landlord.

If access to the Building roof is required by Tenant at times other than normal business hours, Landlord reserves the right to charge Tenant any actual costs incurred by Landlord for overtime wages to Landlord's employees or contractors.

-17-

Tenant shall obtain and maintain all necessary FCC licenses, if any, and all other governmental approvals, licenses, and permits required to operate Tenant's Equipment, which operation shall not interfere with the quiet enjoyment of any other tenants within the Building.

Tenant agrees that Landlord hereafter shall have the right to install and to grant others the right to install transmitting equipment, satellite dishes, antennae, and similar equipment on the roof of the Building, so long as neither the installation nor operation of such equipment interferes with the operation of Tenant's Equipment.

Tenant agrees that transmissions from Tenant's Equipment shall not cause interference with transmissions of other persons currently operating communications equipment in the business community in which the Building is located. Upon written notification from Landlord of such interference, Tenant shall immediately stop operation of Tenant's Equipment and not resume operation until such interference is cured. Any future agreement granting another tenant of the Building or any other person the right to make rooftop installations shall contain a covenant by such other tenant or person that its installation and operation of rooftop equipment will not interfere with the operation of Tenant's Equipment, and that if such interference occurs, such other tenant or other user shall cease installation or operation of its equipment until such interference is cured.

24. PURCHASE OPTION. Prior to Landlord listing or actively marketing the Building for sale, Tenant shall have the right of first offer to purchase the Building and the real property on which the Building is located. Prior to listing the Building for sale or otherwise offering the Building for sale to any party, unless in the event of exchange or trade, Landlord shall provide Tenant with notice of the availability of the Building for purchase. This notice will identify the Landlord's intended purchase price for the property (assuming no sales commissions) and any other material terms of a proposed sale. Tenant shall have ten (10) business days following receipt of such notice to notify Landlord of its intent to accept the same, in which event the parties shall promptly enter into a mutually acceptable real property purchase and sale agreement containing the agreed material terms and other terms generally consistent with comparable commercial real property sales agreements in the Seattle metropolitan area.

25. TELEPHONE SERVICE. If Tenant desires telephonic or any other electric connection, Landlord, with Tenant's help, will direct the electricians as to where and how the wires are to be introduced, and without such directions no boring or cutting external to the Premises for wires in installation thereof will be permitted. Tenant shall supply its own requirements for telephone service with respect to the Premises and shall be allowed to select its providers for telecommunications and other services. Tenant or its service providers, without charge, shall be allowed to install T-1 lines, multiple points of entry, and other special telecommunication facilities, including cabling and connections from service providers to the Premises. Landlord shall, without charge, cooperate as needed with Tenant's telecommunications and other service providers, including, without limitation providing Building information, providing closet space in the basement of the Building, and signing required authorizations for installation.

26. RISK. All personal property of any kind or description whatsoever in the demised Premises shall be at Tenant's sole risk. Landlord shall not be liable for any damage done to or loss of such personal property or damage or loss suffered by the business or occupation of the Tenant arising from any acts or neglect of co-tenants or other occupants of the Building, or of Landlord or the employees of Landlord, or of any other persons, or from bursting, overflowing or leaking of water, sewer or steam pipes, or from the heating or plumbing or sprinklering fixtures, or from electric wires, or from gas, or odors, or caused in any other manner whatsoever except in the case of

-18-

negligence or intentional acts on the part of Landlord or its agents. Tenant shall keep in force throughout the term of this lease such casualty, general liability and business interruption insurance as a prudent tenant occupying and using the Premises would keep in force.

27. INSOLVENCY. If Tenant becomes insolvent, or makes an assignment for the benefit of creditors, or a receiver is appointed for the business or property of Tenant, or a petition is filed in a court of competent jurisdiction to have Tenant adjudged bankrupt and either remains undismissed or a period of sixty (60) days or results in the entry of an order of relief against Tenant which is not fully stayed within sixty (60) days after entry, then Landlord may at Landlord's option terminate this Lease. Said termination shall reserve unto Landlord all of the rights and remedies available under Section 19 hereof, and Landlord may accept rents from such assignee or receiver without waiving or forfeiting said right of termination.

28. BINDING EFFECT. The parties hereto further agree with each other that each of the provisions of this Lease shall extend to and shall, as the case may require, bind and inure to the benefit, not only of Landlord and Tenant, but also of their respective heirs, legal representatives, successors and assigns, subject, however, to the provisions of Section 18 of this Lease.

It is also understood and agreed that the terms "Landlord" and "Tenant" and verbs and pronouns in the singular number are uniformly used throughout this Lease regardless of gender, number or fact of incorporation of the parties hereto. The typewritten riders or supplemental provisions, if any, attached or added hereto are made a part of this Lease by reference. It is further mutually agreed that no waiver by Landlord of a breach by Tenant of any covenant or condition of this Lease shall be construed to be a waiver of any subsequent breach of the same or any other covenant or condition.

29. HOLDING OVER. If Tenant holds possession of the Premises after the term of this Lease, Tenant shall be deemed to be a month-to-month tenant upon the same terms and conditions as contained herein, except rent which shall be revised to reflect 125% of the then current amount due under the Lease. During any month-to-month tenancy, Tenant acknowledges Landlord will be attempting to relet the Premises. Tenant agrees to cooperate with Landlord and Tenant further acknowledges Landlord's right to terminate the Lease with proper notice.

30. TIME FOR PERFORMANCE. If any date for performance hereunder falls on a day that is a Saturday, Sunday or legal holiday, then such performance shall be due on the next business day thereafter.

31. ATTORNEY'S FEES. If any legal action is commenced to enforce any provision of this Lease, the prevailing party shall be entitled to an award of reasonable attorney's fees and disbursements including those on appeal.

32. NO REPRESENTATIONS. Neither party has made any representations or promises except as contained herein.

33. QUIET ENJOYMENT. So long as Tenant pays the rent and performs the covenants contained in this Lease, Tenant shall hold and enjoy the Premises peaceably and quietly, subject to the provisions of this Lease.

-19-

34. RECORDATION. Tenant shall not record this Lease without the prior written consent of Landlord, whose consent shall not be unreasonably withheld, conditioned or delayed. However, at the request of Landlord, both parties shall execute a memorandum or "short form" of this Lease for the purpose of recordation in a form customarily used for such purpose. Said memorandum or short form of this Lease shall describe the parties, the Premises and the Lease term, and shall incorporate this Lease by reference. Notwithstanding the foregoing, however, Tenant may record or file this Lease with the SEC as required by SEC rules and other regulations.

35. MUTUAL PREPARATION OF LEASE. It is acknowledged and agreed that this Lease was prepared mutually by both parties. In the event of ambiguity, it is agreed by both parties that it shall not be construed against either party as the drafter of this Lease.

36. GOVERNING LAW. This Lease shall be exclusively governed by, construed and enforced in accordance with the laws of the State of Washington.

37. REAL ESTATE COMMISSION. Landlord and Tenant hereby acknowledge that Washington Partners, Inc. ("Broker") represented Tenant in this transaction and is due a Leasing Fee equivalent to $7.50 per RSF leased. This Leasing Fee is an agreed obligation payable by Landlord to Broker. However, the parties agree that Tenant shall pay the Leasing Fee to Broker in full upon full execution and delivery of this Lease and, in turn, shall be entitled to credits therefor as pre-paid rent for months 12, 24, 48 and 72 of the Initial Term hereof as otherwise provided in Sections 1(n) and 5(b) above herein. To the extent, if any, that the Pre-Paid Rent attributable to months 12, 24, 48 and 72 exceeds the Leasing Fee, Tenant shall pay any such excess to Landlord as soon as the same is ascertainable. Each party shall indemnify and hold the other harmless from any claim for a commission by any other broker allegedly acting on such party's behalf.

38. NOTICES. Any notice under this Lease must be in writing and be personally delivered, delivered by recognized overnight courier service or given by mail or via facsimile. Any notice given by mail must be sent, postage prepaid, by certified or registered mail, return receipt requested.

TENANT WORK LETTER

F5 Networks, Inc. (hereinafter called "Tenant") and Selig Real Estate Holdings XXV, LLC (hereinafter called "Landlord") are executing simultaneously with this Tenant Improvement Work Letter (the "Work Letter") and a written Lease (the "Lease") for space in the building known as 333 Elliott West, Seattle, Washington 98119. As further consideration to entering into the Lease, Landlord and Tenant mutually agree to the following terms and conditions.

I. LANDLORD WORK AT LANDLORD EXPENSE

Landlord shall complete the Building Shell and Core in substantial accordance with Exhibit D to the Lease entitled Building Shell and Core Outline Specifications (the "Landlord Work"). As used in this Lease, the "Delivery Date" shall be the date the Premises are sufficiently complete to allow Tenant to commence construction of Tenant's improvement work (the "Tenant Work") when Landlord has substantially completed the following items of its Landlord Work and delivered possession of the Building to Tenant for the purpose of commencing the Tenant Work including the following, provided that in the event the Delivery Date is delayed due to Tenant Delay, then the Delivery Date shall be the date on which the Delivery Date would have occurred but for the Tenant Delay:

A. Building is fully enclosed and water tight, including the roof and permanent exterior walls and windows.

B. Power and lighting and electrical service all available as described in Exhibit D to the Lease for distribution by the Tenant; and

C. There shall be evidence reasonably satisfactory to Tenant that:

1. The balance of the Landlord Work can be completed prior to the Lease Commencement Date; and

2. The Tenant's contractor is able to proceed efficiently with the Tenant Work, subject to a requirement of reasonable coordination and cooperation with Landlord's Shell and Core contractor.

Tenant may begin the Tenant Work prior to the above items being completed at Tenant's election, provided that the Tenant's decision to begin the Tenant Work shall not interfere with the Landlord's Substantial Completion of the Premises.

Except as set forth above and as defined in Exhibit D, all work, improvements, finishes and/or equipment required by Tenant and/or specified in the approved Tenant Plans for the Premises shall be considered the Tenant Work.

II. LANDLORD WORK AT TENANT EXPENSE

C-1

Upon request by Tenant, Landlord will have certain Building Shell and Core work that exceeds the scope of the Landlord Work, as defined above, completed during the normal course of construction of the Building Shell and Core. This work shall hereinafter be referred to as "Shell and Core Tenant Upgrades." Once the scope of the Shell and Core Tenant Upgrades are known, Landlord shall provide Tenant with a budget for these Upgrades. All Shell and Core Tenant Upgrades, including the cost for same, shall be authorized in writing by Tenant and approved in writing by Landlord on the same basis as the approval of Tenant's Plans (see Section III.A.4 below). All Shell and Core Tenant Upgrades shall be performed by Landlord's contractor under Landlord's supervision.

III. THE TENANT WORK

A. TENANT'S PLANS. Tenant shall employ an architect/space planner ("Tenant's Architect") as its architect to provide information to Landlord as necessary for the completion of Shell and Core Tenant Upgrades and to prepare architectural drawings and specifications for all layout and improvements to the Premises not included in the Landlord Work. Tenant shall also employ all necessary engineers (the "Tenant's Engineers") to prepare technical working drawings and specifications for all the Tenant Work, including structural alterations, mechanical and electrical work. All such drawings and specifications are referred to herein as "Tenant's Plans" and shall include the "Preliminary Plans", "M&E Working Drawings" and "Issued for Construction Documents" all of which are hereinafter defined. Tenant's Plans shall be in form and detail sufficient to secure all required governmental approvals and shall be completed on Auto-Cad (Version 14 or higher).

Tenant's Architect and Tenant's Engineers shall be reasonably acceptable to Landlord and Tenant. McKinstry Co. (mechanical) and the Gerber (electrical) are hereby approved as Tenant's Engineers for mechanical and electrical engineering work. Other architects and engineers required in the course of Tenant's Plans will be as mutually approved.

1. PRELIMINARY PLANS. The Preliminary Plans shall be a schematic plan (1/8" scale) for the Premises for special structural and loading requirements in excess of those provided for in Exhibit D __________________ will be provided to Landlord prior to January 1, 2007. The cost of increasing the floor loads beyond those identified in Exhibit D, shall be a Shell and Core Tenant Upgrade.

2. MECHANICAL AND ELECTRICAL ENGINEERED WORKING DRAWINGS AND SPECIFICATIONS ("M & E WORKING DRAWINGS"). The Tenant Plans shall be engineered to provide for complete mechanical and electrical operating systems. Tenant shall contract with Tenant Engineers and cause them to prepare M & E Working Drawings showing complete plans for electrical and mechanical systems including but not limited to, life safety, automation, plumbing, and air cooling, ventilating, heating and temperature controls. Tenant shall use Landlord's engineers for this work: Key (mechanical) and Sparling & Associates (electrical) with the Tenant also having the option to use McKinstry Co. and Gerber.

3. ISSUED FOR CONSTRUCTION DOCUMENTS. The Issued for Construction Documents shall consist of all drawings (1/8" scale) and specifications necessary to construct all Tenant Work in form and detail sufficient to secure all required governmental approvals and to demonstrate conformity with the Landlord's standards and quality. Tenant's Architect and

C-2

Tenant's Engineers are responsible for having all mechanical, electrical, life safety and Tenant Work required structural drawings complete.

4. APPROVAL BY LANDLORD. Tenant's Plans shall be subject to Landlord's approval, which approval shall not be unreasonably withheld, conditioned or delayed. Landlord shall be entitled to withhold approval if the proposed plans and specifications (i) interfere with the structural integrity of the Building, (ii) overload the utility systems of the Building, (iii) violate any applicable laws or regulations, or (iv) materially affect the architectural integrity of the Building. If Landlord disapproves of any of Tenant's Plans, Landlord shall advise Tenant in reasonable detail of required revisions and the reasons therefor. After being so advised by Landlord, Tenant shall promptly submit a redesign, incorporating the revisions required by Landlord, for Landlord's approval. If Tenant has reason to dispute any Landlord disapproval, then the parties shall meet within 5 days and attempt to resolve the dispute.

If the Parties are unable to resolve their differences as to Tenant's Preliminary Plans within 5 days after meeting, then either party may initiate an arbitration procedure by notifying the other Party of the need to submit their disagreements to binding and final arbitration by a mutually acceptable arbitrator with at least ten (10) years commercial office design experience. If the parties are unable to agree on the arbitrator within a period often (10) days of notice, then either party may request resolution by a single arbitrator before the American Arbitration Association, as set forth at the end of Lease Section 3(c).

5. SUBMISSION BY TENANT. Tenant shall submit Tenant's Plans to Landlord on or before the following dates:

January 1, 2007: Structural floor load requirements.

August 1, 2007: All remaining Tenant Plans.

6. PERMITS. Tenant shall be responsible for the cost and scheduling of the submission of Tenant's Plans, in a timely manner, for plan check by the City of Seattle and the obtaining of a building permit for the Tenant Work; excepting all permits required for the communication conduits addressed in the "Communications and Data Considerations" section of Exhibit D to the Lease, which shall be Landlord's responsibility.

B. TENANT IMPROVEMENT CONSTRUCTION

1. Tenant shall be responsible for the construction of the Tenant Work in accordance with approved Tenant Plans.

2. Tenant shall, upon completion of Tenant's Plans, directly contract for the Tenant Work itself. When a contract is executed between the selected contractor and Tenant, said contractor shall be referred to as "Tenant's Contractor." Tenant agrees to cooperate with Landlord and Tenant's Contractor in the completion of the Tenant Work by responding to Landlord's and Tenant's Contractor's requests for information in a timely fashion and Landlord agrees to respond similarly to Tenant and Tenant's Contractor.

3. Tenant shall submit to Landlord a preliminary cost estimate for the Tenant Work

C-3

and shall provide to Landlord a final pricing for the Tenant Work when received from Tenant's Contractor but not later than fifteen
(15) days prior to the commencement of the Tenant Work.

4. Tenant's construction contract with Tenant's Contractor shall be a guaranteed maximum price contract (the "Tenant Improvement Construction Contract") and shall contain a construction schedule (the "Tenant Improvement Construction Schedule") for construction of the Tenant Work. The guaranteed maximum price specified in the Construction Contract shall include all costs and fees for construction of the Tenant Work with the exception of any required governmental permit fees, professional fees and Washington State Sales Tax.

C. SCHEDULE. Provided that Tenant meets the scheduled deadlines for preparation and approval of Tenant's Plans, the Delivery Date, subject to any Tenant Delay or Force Majure Event, shall be November 1, 2007.

D. LANDLORD'S ALLOWANCE FOR TENANT WORK

1. Landlord shall provide to Tenant a total "Tenant Allowance" as provided in Section 21 of the Lease. The Tenant Allowance shall be applied first toward the costs relating to Shell and Core Tenant Upgrades, if any, including applicable Washington State Sales Tax, then toward the construction of the Tenant Work shown on the final approved Tenant's Plans, including applicable Washington State Sales Tax. 2. Landlord shall pay the cost of the Tenant Work, up to the maximum allowance, directly to the Tenant as more fully described in Section IV below.

E. TENANT DELAY

The term "Tenant Delay" shall mean any delay in the occurrence of the Delivery Date or completion of Landlord's Work resulting from:

(a) Any Tenant materials, finishes or installations called for on the Tenant Plans which are not readily available and, as a result, adversely affect the schedule;

(b) Any modification by Tenant to the Tenant's Plans that adversely affects the schedule; or

C-4

(c) Any act by Tenant or its agents and contractors in installing any tenant fixtures or equipment that unreasonably delays the issuance of the Certificate of Occupancy or temporary Certificate of Occupancy for the Premises.

Landlord shall make commercially reasonable efforts to mitigate the effect of any event that would otherwise cause Tenant Delay, provided that Landlord shall not be required to expend additional funds to mitigate Tenant Delay unless Tenant agrees in writing to reimburse Landlord for such costs.

F. LANDLORD DELAY

The term "Landlord Delay" shall mean those construction events within the reasonable control of Landlord (i.e. excluding Tenant Delay or Force Majeure Event) to the extent such event causes:

(a) a material and unexpected interference with Tenant's construction of the Tenant Work and resulting delay in substantial completion of the Tenant Work, or

(b) a delay in the Delivery Date beyond the date specified in the Lease and this Exhibit C.

Tenant shall make commercially reasonable efforts to mitigate the effect of any event that would otherwise cause Landlord Delay, provided that Tenant shall not be required to expend additional funds to mitigate Landlord Delay unless Landlord agrees in writing to reimburse Tenant for such costs.

G. COOPERATION

The parties agree to use best efforts to cause each of their respective consultants, architects, engineers and contractors to cooperate with one another so that the Landlord Work and Tenant Work are promptly, diligently and efficiently constructed.

H. PUNCH LIST

Within twenty (20) days after Completion of the Building Shell and Core, Tenant shall supply to Landlord a written punch list setting forth readily apparent additional corrective non-warranty work to the Building Shell and Core which Tenant believes is required to be performed pursuant to the requirements of Exhibit D. Once Landlord has been provided with a punch list in accordance with the foregoing, and agrees with the content of the punch list, Landlord shall within thirty (30) days of receipt of the punch list take such measures as are necessary to correct such defective work.

IV. ADMINISTRATION OF WORK

A. LANDLORD REIMBURSEMENT

1. Landlord shall at the direction of Tenant either reimburse Tenant or directly pay Tenant's Contractor (up to the maximum amount of the Tenant Allowance remaining after reductions for Shell and Core Tenant Upgrades) for the Tenant Work on a monthly basis, within twenty (20) days after the receipt and approval from the representative of the Landlord's Construction Lender of a draw request from Tenant's contractor, accompanied by a signed Application and Certificate

C-5

for Payment (in AIA format) from Tenant's Architect confirming that the work covered by such draw request has been completed to its satisfaction. So long as the draw request is accompanied with the proper documentation as noted, Landlord's Construction Lender shall not withhold its approval and shall agree to pay such draw request when due; in the event Landlord's Construction Lender delays or withholds payment of any such draw request for any reason other than Tenant's non-compliance with the Lease and this Exhibit C, Landlord shall then promptly fund the draw request notwithstanding the Lender's position. This payment request shall also be accompanied by partial conditional lien releases from Tenant's Contractor covering the Tenant Work performed and/or materials and labor supplied through the date of each application for payment and full conditional lien releases from each subcontractor and supplier which has at that stage completed its work and confirmation from Tenant that its general contractor is not in default and that the percentage of work completed on the draw request is accurate. The reimbursement shall be calculated on a percentage-of-completion basis. After completion of one hundred percent (100%) of the Tenant Work, Landlord shall either reimburse Tenant or directly pay Tenant's Contractor for the then unreimbursed balance of the allowance for the Tenant Work minus any mutually agreed holdback for uncompleted punch list items, within thirty (30) days following receipt of a schedule reflecting such costs, together with paid invoices supporting such costs, and satisfaction of all of the following conditions:
