                                LEASE AGREEMENT

THIS LEASE is made as of this 23rd day of April, 1998, between Pine Forest Co.,
a Washington corporation (hereinafter called "Landlord") and INTERLINQ Software 
Corporation, a Washington corporation (hereinafter called "Tenant").

1.   PREMISES.

     Landlord hereby leases to Tenant and Tenant hereby leases from Landlord 
     the entire two story office building and all related improvements and 
     appurtenances (including without limitation pavement, curbs and gutters, 
     sidewalks and landscaping located on real property at 12000 N.E. 24th 
     Street, Bellevue, Washington 98005, and legally described in Exhibit "A" 
     attached hereto and incorporated by this reference (hereinafter 
     collectively called "Premises"). Tenant shall use and occupy the Premises 
     for general office purposes, with a computer server room, lunch room with 
     food preparation for employees, athletic facilities for employees, and 
     other uses customary for a software development company, and for no other 
     use or purpose without the prior written consent of Landlord.

2.   TERM AND POSSESSION.

          (a)  The Term of this Lease shall be for the period specified in the 
     Basic Lease Information, as that Term may be extended or terminated as 
     provided herein. Landlord shall use its best reasonable efforts to 
     deliver the Premises to Tenant on November 1, 1998. All permits required 
     to construct the structural portions of the building shell and core have 
     been obtained. The applications for tenant improvement permits have not 
     yet been submitted. If Landlord cannot deliver possession by November 1, 
     1998, and such failure is not attributable to Landlord's gross negligence 
     or willful misconduct, this Lease shall not be void or voidable, nor shall 
     Landlord or its agent be liable to Tenant for any loss or damage 
     resulting therefrom. Tenant shall not be liable for any rent until the 
     Commencement Date (defined below) unless Tenant is responsible for a delay 
     as provided in Exhibit B, Paragraph 14, in which case Tenant shall begin 
     paying Rent as of the date that would have been the Commencement Date but 
     for the Tenant Delay. If Landlord tenders possession of the Premises to 
     Tenant prior to November 1, 1998, and the requirements for the 
     Commencement Date have been met then the Term of this Lease and Tenant's 
     obligations hereunder shall commence on the date that Landlord delivers 
     such possession, if Tenant takes possession. Any failure to deliver
     possession by November 1, 1998 or delivery of possession prior to the
     Commencement Date shall not in any way affect the obligations of Tenant
     hereunder to lease the Premises.

          (b)  The Commencement Date shall be the later of November 1, 1998, or 
     the date on which one of the following sets of events has occurred: (i) 
     the Premises have been Substantially Completed in accordance with the 
     plans and specifications approved by Tenant and, the City of Bellevue has 
     completed its inspection, approved the 


                                       4
<PAGE>   7
     Premises for occupancy by Tenant for its business operations as evidenced
     by issuance of a temporary certificate of occupancy, and the Premises have
     been tendered to Tenant, or (ii) the tenant takes possession of any or all
     of the Premises (except to the extent Tenant is entitled to early access
     pursuant to Paragraph 11, Exhibit B). Tenant's duty to pay Rent under this
     Lease shall commence on the Commencement Date. This Lease shall terminate
     on the day before the anniversary of the Commencement Date in the
     eighty-fourth (84th) month after the Commencement Date, unless sooner
     terminated (the "Termination Date") or extended under the terms of the
     Lease or by agreement of the parties. For example, if the Commencement Date
     were November 1, 1998, then the Termination Date would be October 31, 2005,
     if the Tenant does not exercise its option to extend the term.

          (c)  Landlord agrees to complete construction of the Premises and to
     provide the Tenant Improvements as required in a separate Work Letter
     Agreement attached hereto as Exhibit "B" and made a part hereof. The term
     Substantial Completion as used in this Lease shall have the same meaning as
     that term is used in the Work Letter Agreement.

          (d)  At either party's request both Landlord and Tenant will execute
     and deliver to each other a written statement specifying the Commencement
     Date and Termination Date.

          (e)  If the Commencement Date has not occurred by March 1, 1999, and
     said delay is not caused by tenant's Delay or force majeure as described in
     paragraph 36 of this Lease, then tenant may terminate this Lease by written
     notice to Landlord; provided however that if the delay in the Commencement
     Date is caused by Tenant Delay or by force majeure as described in
     Paragraph 36 of this Lease, then Tenant's termination right in this
     sentence does not arise until June 1, 1999.

3.   RENT.

          (a)  Tenant shall pay Base Rent to Landlord throughout the term of
     this Lease as specified in the Basic Lease Information, without notice.
     Base Rent shall be payable in monthly installments in advance on the first
     day of each month during every year of the term in lawful money of the
     United States, without deduction or offset. It shall be paid to Landlord at
     the address specified in the Basic Lease Information, or to such other firm
     or to such other place as Landlord may from time to time designate in
     writing by notice to Tenant. If this Lease commences on a day other than
     the first day of a calendar month or ends on a day other than the last day
     of a calendar month, the monthly rental for the fractional month shall be
     appropriately prorated based on a thirty (30) day month. "Rent" means Base
     Rent, Tenant's Proportionate Share of Basic Operating Costs and all other
     amounts due pursuant to this Lease.

          (b)  Tenant recognizes that late payment of any Rent or other sum due
     hereunder from Tenant to Landlord will result in administrative expense to
     Landlord, the extent of which additional expense is extremely difficult and
     economically impractical to ascertain. Tenant therefore


                                       5
<PAGE>   8
     agrees that if Rent due hereunder from Tenant to Landlord remains unpaid
     ten (10) days after said amount is due, or any other payment due hereunder
     remains unpaid ten (10) days after written notice from Landlord, then the
     amount of such unpaid Rent or other payment shall be increased by a late
     charge to be paid to Landlord by Tenant in an amount equal to five percent
     (5%) of the amount of delinquent Rent or other payment. The amount of the
     late charge to be paid to Landlord by Tenant on any unpaid Rent or other
     payment shall be reassessed and added to Tenant's obligation for each
     successive monthly period accruing after the date on which the late charge
     is initially imposed. Tenant agrees that such amount is a reasonable
     estimate of the loss and expense to be suffered by Landlord as a result of
     such late payment by Tenant and may be charged by Landlord to defray such
     loss and expense. The provisions of this paragraph in no way relieve Tenant
     of the obligations to pay Rent or other payments on or before the date on
     which they are due, nor do the terms of this paragraph in any way affect
     Landlord's remedies pursuant to paragraph 19 of this Lease in the event
     said Rent or other payment is unpaid after the date due.

4.   RESTRICTIONS ON USE.

     Tenant shall not use or allow the Premises to be used for any unlawful
     purpose. Tenant shall not cause or maintain or permit any nuisance in,  on,
     or about the Premises. Tenant shall not commit or suffer the commission of
     any waste in, on or about the Premises, nor permit any use of the Premises
     which may be hazardous to persons or property. Tenant shall not do or
     permit anything to be done on or about the Premises or bring or keep
     anything therein which will cause an increase in the rate of any insurance
     of the Premises or cause a cancellation of the property and casualty
     insurance or any other insurance on the Premises or otherwise restrict the
     availability of said insurance in any manner.

5.   COMPLIANCE WITH LAWS.

     (a)  Except to the extent any non-compliance is a result of the Tenant
     Improvement Construction Documents (as defined in Exhibit B), Landlord
     warrants that upon delivery to Tenant the Premises shall be in compliance
     with all applicable rules, regulations and codes in effect at the time of
     delivery. Tenant shall not use the Premises or permit anything to be done
     in or about the Premises which would conflict with any law, statute,
     ordinance or governmental rule or regulation now in force or which may
     hereafter be enacted or promulgated. Tenant shall, at its sole cost and
     expense, promptly comply with all laws, statutes, ordinances, and
     governmental rules, regulations, or requirements now in force or which may
     hereafter be in force and with the requirements of any board of fire
     underwriters or other similar body now or hereafter constituted relating to
     its conditions, use or occupancy of the Premises, excluding structural
     changes and other improvements not specifically related to or affected by
     alterations or improvements made by or for Tenant or Tenant's acts. The
     judgment of any court of competent jurisdiction or the admission of Tenant
     in an action against Tenant, whether Landlord be a party thereto or not,
     that Tenant has so


                                       6
<PAGE>   9
     violated any such law, statute, ordinance, rule, regulation, or
     requirement, shall be conclusive of such violation as between Landlord and
     Tenant.

     (b)  "Accessibility Law" means any local, state or federal law, regulation,
     ordinance, order or directive relating to access, use or enjoyment of the
     Premises by, or employment there of disabled persons, or to the removal of
     any tangible or intangible barrier or impediment to access, use or
     enjoyment of the Premises by disabled persons, including, but not limited
     to, the Americans With Disabilities Act and similar state legislation.

     (c)  Notwithstanding anything in this Lease to the contrary, Tenant shall
     make no Tenant alterations after the Commencement Date that violates any
     provision of any applicable rules, regulations and codes, including any
     Accessibility Laws, and all Tenant Improvements shall be in full compliance
     with all such rules, regulations and codes. Tenant shall not adopt or
     otherwise allow to exist any policy or practice related to its use or
     occupancy of the Premises or the conduct of its activities thereon that
     violates any rule, regulation or code. Tenant shall adopt any economically
     feasible policy or practice relating to the conduct of its business at the
     Premises that would cure any existing or future violation of any
     Accessibility Law relating to  the Premises. Tenant shall bear all cost and
     expense of performing its duties under this paragraph. Tenant shall
     reimburse Landlord on demand for any cost or expense required to alter any
     portion of the Premises to comply with any Accessibility Law as a result of
     any Tenant alteration.

     (d)  Notwithstanding any contrary provision of this Lease, Landlord shall
     have no obligation to approve any Tenant alterations if Landlord, in its
     sole discretion, determines that the Tenant alterations would obligate
     Landlord to make alterations of or additions to any part of the Premises in
     order to comply with any Accessibility Law or any other law, ordinance,
     code or regulation, unless Tenant agrees to make such alterations or
     additions at its own cost in the manner provided for other Tenant
     alterations, and Tenant deposits with Landlord, before undertaking the
     design or construction of such alternations, a sum equal to Landlord's
     estimate of the total cost of design and construction of such alterations.
     Notwithstanding the foregoing, Landlord shall have the right at any time,
     without the same constituting an actual or constructive eviction and
     without incurring any liability to Tenant therefor, to change the
     arrangement and/or location of entrances, passageways, doors and doorways,
     corridors, elevators, stairs, toilets, or other public parts of the
     building to the extent such change does not materially affect Tenant's
     business operations if said change is necessary for Landlord to bring the
     Premises into compliance with any rule, regulation or code, including any
     Accessibility Law.


                                       7
<PAGE>   10
     (e)  If any claim is asserted against one or both parties to this Lease
     under any Accessibility Law relating directly or indirectly to any
     violation by either of any of the provisions of this paragraph, such
     alleged violator shall defend, indemnify and hold the other party harmless
     from and against any claims, charges, liabilities, obligations, penalties,
     damages, judgments, costs and expenses (including reasonable attorneys'
     fees and costs) arising directly or indirectly from such violation upon
     determination of a court of competent jurisdiction that such a violation
     did occur and the extent to which the alleged violator is responsible for
     the violation. No approval by either party of any plans or specifications
     for any construction or alterations of the Premises, or failure to
     disapprove any such plans or specifications for construction or alterations
     of the Premises, shall constitute a representation or warranty by either
     party, whether express or implied, that such plans will comply with any
     Accessibility Law.

     (f)  Landlord represents and warrants to Tenant that to the best of
     Landlord's knowledge there are no Hazardous Materials (as defined below) on
     the Premises as of the Commencement Date. Landlord agrees that Tenant is
     not responsible for Hazardous Materials on the Premises prior to the date
     Tenant commences Tenant's Work (as defined in Exhibit B) on the Premises.
     Tenant shall not cause or permit any Hazardous Materials to be brought
     upon, kept or used in or about the Premises, except in compliance with the
     labels on the products, and consistent with the intended use of the
     products for cleaning or other janitorial or maintenance purposes. If
     Tenant breaches its obligations in this paragraph, or if the presence of
     Hazardous Materials caused or permitted by Tenant results in contamination
     of the Premises or any part of any other property or if contamination of
     the Premises or other property otherwise occurs for which Tenant may be
     legally liable to Landlord, unless the contamination is caused solely by
     Landlord or its agents, employees, contractors or invitees, Tenant shall
     defend, indemnify and hold Landlord harmless from any and all claims,
     judgments, damages, penalties, fines, liabilities or losses (including,
     without limitation diminution in value of the Premises, damages for the
     loss or restriction on use of the Premises, damage arising from any adverse
     impact on marketing or leasing of the Premises, damages to any other
     property and amounts paid in settlement of claims, attorney fees and costs,
     consultant fees and expert fees) which arise during or within five (5)
     years after the end of the Term or extended Term as a result of such
     contamination. If Landlord breaches its warranty above, or if the  presence
     of Hazardous Materials which is caused solely by Landlord results in
     contamination of the Premises or any part of any other property. Landlord
     shall defend, indemnify and hold Tenant harmless from any and all claims,
     judgments, damages, penalties, fines, liabilities or losses (including,
     without limitation diminution in value of the leasehold estate in the
     Premises, damages for the loss or restriction on use of the Premises,
     damages to any other property and amounts paid in settlement of claims,
     attorney fees and costs, consultant fees and expert fees) which arise
     during or within five years after the end of the Term or extended Term as a
     result of such 


                                       8
<PAGE>   11
     contamination. Without limiting the foregoing, the indemnification stated
     above includes, without limitation, reasonable costs incurred in connection
     with any investigation of site condition or any clean up, remedial, removal
     or restorative work required by any federal, state or local government
     agency or political subdivision because of Hazardous Materials present at
     the Premises due to acts of the indemnifying party. If the presence of any
     Hazardous Material caused or permitted by either party results in any
     contamination of the Premises or any other part of the property, then that
     party shall promptly take all actions, at its sole expense, as are
     necessary to return the Premises and any other property to the condition
     existing prior to the introduction of such Hazardous Material. Prior to
     commencing such action, the acting party shall obtain the other party's
     approval, which approval shall not be unreasonably withheld, or delayed so
     long as such actions would not potentially have any material adverse
     long- or short-term effect on the Premises or other property. As used
     herein, the term "Hazardous Materials" means any hazardous, dangerous,
     toxic or harmful substance material or waste which is or becomes regulated
     by any local or federal governmental authority, including the State of
     Washington or the United States government.

6.   ALTERATIONS.

     (a)  Tenant shall not make or suffer to be made any alterations, additions,
     or improvements in, on, or to the Premises or any part thereof after the
     Commencement Date ("Tenant Alterations") without the prior written consent
     of Landlord, which shall not be unreasonably withheld or delayed. All
     contractors, laborers, materialmen and professionals who perform work on
     the Premises shall agree to provide to Landlord a conditional lien release
     prior to release of any payment to them for work they performed as required
     in paragraph 8 herein.

     (b)  At the time Tenant requests Landlord's permission to make Tenant
     Alterations, Tenant may request Landlord to designate in writing whether
     said proposed Tenant Alteration shall become part of the leasehold or
     whether Landlord wishes Tenant to remove said Tenant Alteration upon
     termination the Lease. Landlord and Tenant shall be bound by any such
     written agreement. If Tenant does not request Landlord to designate in
     writing whether said Tenant Alteration will become part of the leasehold,
     Landlord may make that determination when the Lease is terminated. Said
     determination by Landlord shall be at Landlord's sole option and shall be
     binding on Tenant.

     Notwithstanding the foregoing, Tenant's movable furniture, equipment and
     trade fixtures are Tenant's personal property. Upon the expiration or
     sooner termination of the Term, Tenant shall, at Tenant's sole cost and
     expense, forthwith and with all due diligence remove all Tenant's personal
     property and any or all Tenant Alterations which were designated by
     Landlord to be removed either at the time installed or, if not determined
     at that time as provided above, then prior to or when the Lease is
     terminated. Tenant shall forthwith and with all due diligence, at its sole
     cost and expense, repair any damage to the Premises resulting from removal
     of Tenant's personal property and


                                       9
    
<PAGE>   12
     Tenant Alterations at the end of the Term, so as to restore the Premises to
     the condition that existed on the Commencement Date subject to ordinary
     wear and tear, damage by casualty or by the negligence or willful
     misconduct of Landlord or the gross negligence or willful misconduct of
     Landlord's agents or employees.

     (c)  If, after the Commencement Date, Landlord makes any changes,
     alterations or additions to the Premises, landlord will use its best
     efforts to make such changes, alterations or additions without unreasonably
     interfering with the public access to the Premises, including Tenant's
     parking, and without interfering with Tenant's utility services, including
     without limitation all electricity, gas, water, sewer, HVAC and
     telecommunications services to the Premises. If such interference to
     utility services should occur, Landlord shall make reasonable efforts to
     restore such accessibility or services in coordination and cooperation with
     Tenant. If such interference with electricity, gas, water, sewer or
     telecommunication services occurs due to the acts or omissions of Landlord,
     its agents or employees and such interference is not cured within five (5)
     days of Tenant's written notice to Landlord, on the sixth day all Rent due
     under the lease shall abate until such interference is cured, and Tenant
     may engage in such measures as it sees fit to cure the interference at
     Tenant's sole cost so long as Tenant gives Landlord twenty four (24) hours
     prior actual notice of its intended actions hereunder and Landlord
     expresses no reasonable objection to such actions within twenty four (24)
     hours of receiving the notice. If the flow of electricity to the Premises
     is interrupted, Tenant may install a generator on the Premises at Tenant's
     sole expense and risk so long as such installation is in full compliance
     with all applicable rules, regulations and codes. Tenant hereby agrees to
     defend, indemnify and hold Landlord harmless from any loss, injury to
     persons or property, death of any person or any other damage or loss
     related to Tenant's installation or use of the generator and/or replacement
     of Tenant's uninterruptible power supply with said generator.

7.   REPAIRS.

     (a)  By taking possession of the Premises, Tenant accepts the Premises as
     being in the condition in which Landlord is obligated to deliver them and
     otherwise in good order, condition and repair. Landlord shall provide
     janitorial service and keep the Premises in clean condition and good
     repair, maintain all plumbing fixtures, HVAC systems, window and door
     glass, landscaping and all other systems so they remain in good condition
     and shall otherwise maintain the cleanliness and condition of the Premises,
     ordinary wear and tear, damage by Tenant's negligence or that of its
     agents, employees, invitees and licensees and damage from condemnation or
     casualty excepted. Tenant shall, at all times during the Term, reimburse
     the Landlord for the cost of keeping the Premises and every part thereof in
     good order, condition and repair, ordinary wear and tear and damage by
     casualty or Landlord's negligence or the gross negligence of Landlord's
     agents and employees excepted. Tenant shall pay said costs as part of Basic
     Operating Costs pursuant to paragraph 27. Tenant shall upon the expiration
     or sooner termination of



                                       10
<PAGE>   13
     the Term, surrender to Landlord the Premises, neat and clean and in the
     same condition as when received, ordinary wear and tear and damage caused
     by Landlord's negligence and the gross negligence of Landlord's agents or
     employees, casualty or condemnation excepted. Tenant agrees that Landlord
     has no obligation to alter, remodel, improve, or decorate, or paint the
     interior of the Premises or any part thereof after the Commencement Date
     and that no representations respecting the condition of the Premises have
     been made by Landlord to Tenant, except as specifically set forth in this
     Lease.

     (b)  Landlord shall at its cost without pass-through to Tenant keep the
     roof, gutters, power service to the Premises, exterior walls, foundations
     and building structure of the Premises in a good state of repair, and shall
     accomplish such repairs as may be needed within a reasonable time after
     receipt of written notice from Tenant. Except as expressly provided for
     herein, there shall be no abatement of Rent and no liability of Landlord by
     reason of any injury to or interference with Tenant's business arising from
     the making of any repairs, alterations or improvements in or to any portion
     of the Premises, building or in or to any fixtures, appurtenances and
     equipment therein except to the extent caused by the Landlord's negligence
     or the gross negligence or willful misconduct of Landlord's agents or
     employees.

     (c)  If the Landlord fails to make any repairs or perform any work required
     herein or otherwise fails to maintain the Premises in the condition
     provided herein, Tenant shall so notify Landlord in writing. If after
     thirty (30) days prior written notice from Tenant (except in emergency or
     cases of urgent necessity, or for anything that cannot be done in such time
     period, or after such longer period as may reasonably be required to
     accomplish the required tasks), Landlord fails to keep and preserve the
     Premises as set forth in this paragraph, Tenant may, put or cause the same
     to be put in the appropriate condition and state of repair, at its option.
     Tenant must first give twenty (20) days written notice to Landlord of
     Tenant's intention of making the repair and the cost to be incurred. In
     such case, upon receipt of written statements and evidence of payment from
     Tenant, Landlord shall promptly reimburse the entire cost thereof to
     Tenant. If Landlord fails to reimburse Tenant within thirty (30) days of
     demand and receipt of the written statements and evidence of payment from
     Tenant, Tenant may offset the unreimbursed portion of the cost from the
     Rent, so long as Tenant is in complete compliance with this paragraph and
     there is no dispute as to Tenant's right to reimbursement. Notwithstanding
     the foregoing, if such work was required because of Tenant's negligent acts
     or failure to abide by this Lease, Tenant shall promptly pay Landlord for
     the total cost of all such work as Additional Rent.

8.   LIENS.
     
     Tenant shall keep the Premises free from any liens arising out of any work 
     performed, material furnished, or obligations incurred by Tenant subject 
     to Tenant having the right to contest any lien in good faith and by 
     taking the steps necessary to protect Landlord and its interest from any 
     negative consequence of such contest. Tenant shall not permit

                                       11

 

   
<PAGE>   14
     any person or entity to commence work on the Premises unless said person 
     has agreed to provide Tenant and Landlord with conditional lien releases 
     upon payment of each draw request. Tenant shall deliver to Landlord a duly 
     executed conditional lien release in which said person or entity agrees to 
     waive and release all his/her/its right to claim a lien on the Premises 
     for work performed and paid for and shall deliver a final lien release at 
     completion of the work. In the event that Tenant has not, within ten (10) 
     days following the imposition of any lien, caused the same to be released 
     of record by payment or posting of a proper bond or otherwise satisfying 
     Landlord's concern, Landlord shall, in addition to all other remedies 
     provided herein and at law, have the right, but not the obligation, to 
     cause the same to be released by such means as it shall deem proper, 
     including payment of the claim giving rise to such lien. All such sums 
     paid by Landlord and all reasonable expenses incurred by it in connection 
     therewith shall be considered Additional Rent and shall be payable to it 
     by Tenant on demand with interest at the rate payable of twelve percent 
     (12%) per annum or four percent (4%) above the prime rate of US Bank, 
     whichever is greater. Landlord shall have the right at all times to post 
     and keep posted on the Premises any notices permitted or required by law, 
     or which Landlord shall deem proper, for the protection of Landlord, the 
     Premises, and any other party having an interest therein, from mechanics' 
     and materialmen's liens. Tenant shall give to Landlord at least five (5) 
     business days prior notice of commencement of any construction on the 
     Premises. Tenant shall not permit any lien to be placed on the Tenant's 
     interest in the Premises by operation of law.

9.   ASSIGNMENT OR SUBLETTING.
     
     Tenant shall not sell, assign, encumber or otherwise transfer by operation 
     of law or otherwise this Lease or any interest herein, sublet the Premises 
     or any part thereof, or suffer a person to occupy or use the Premises or 
     any portion thereof, without the prior written consent of Landlord, which 
     shall not be unreasonably withheld or delayed. A transfer by the present 
     majority shareholders of ownership and control of the voting stock of a 
     corporate tenant, or a transfer of a controlling interest in a partnership,
     limited liability company, or proprietorship, as applicable, shall be 
     deemed an assignment for the purposes of this paragraph except as follows 
     in paragraph 9a:

     (a)  Any change in ownership of Tenant resulting from (i) a public offering
     of the stock of Tenant or any parent of Tenant or (ii) any transfer of
     stock or assets from Tenant to an affiliate or subsidiary corporation or
     other entity that controls or is controlled by Tenant or (iii) as a result
     of any merger, consolidation or other reorganization of Tenant or parent of
     Tenant shall not be deemed an assignment if all of the following conditions
     are met: Said assignee is an entity organized in the United States with its
     principal office in the United States and is as financially sound as
     Tenant. If the assignee is not organized in the United States and/or does
     not have its principal business office located in the United States, Tenant
     may assign the Lease to said entity if the assignee provides a guarantor
     whose assets are located in the United States that is as financially sound
     as the

                                       12

      
<PAGE>   15
     Tenant. The assignee or guarantor shall be deemed to be as financially
     sound as Tenant if (i) the assignee or guarantor has unencumbered liquid
     assets located in the United States which are equal to or greater in value
     than 125 percent of the value of the unencumbered liquid assets of Tenant
     on the Commencement Date, and (ii) the assignee's or guarantor's net assets
     located in the United States as determined using Generally Accepted
     Accounting Principles consistently applied, are equal to or greater in
     value than 125 percent of the value of Tenant's net assets on the
     Commencement Date, and (iii) the assignee or guarantor has not been the
     subject of any bankruptcy proceeding or action by a prior Landlord within
     the seven years prior to the date of the assignment, (iv) the assignee has
     been in continuous operation of its business for the five years prior to
     the date of the assignment, and (v) no prior Landlord has commenced
     proceedings or refused to renew or extend a lease because of untimely
     payment of rent or damage to the Premises, as evidenced in writing by such
     prior landlord, within ten (10) years prior to the proposed assignment. In
     addition, the Landlord may agree with Tenant that a proposed assignee or
     guarantor is as financially sound as Tenant without regard to the foregoing
     objective standard.

     (b)  Any other transfer, assignment or subletting shall be deemed a
     prohibited transfer pursuant to this paragraph and shall be subject to
     prior written permission of the Landlord, which shall not be unreasonably
     withheld or delayed.

     (c)  Tenant shall, by written notice, advise Landlord of its desire from
     and after a stated date (which shall not be less than thirty (30) days or
     more than ninety (90) days after the date of Tenant's notice), to assign
     the Lease or sublet the premises or any portion thereof. Said notice by
     Tenant shall state the name and address of the proposed assignee or
     subtenant. Requests shall include audited or reviewed financial statements
     of assignee or sublessee and such other financial information as Landlord
     reasonably requests. Tenant shall include a true and complete copy of the
     proposed terms of the assignment or sublease. Such notice shall specify an
     effective date which shall be the first day of a calendar month and shall
     be not less than 30 days after the date of such notice. Landlord agrees to
     respond to Tenant's request for consent within ten (10) business days of
     receipt of the request and all required information. Failure to respond to
     Tenant within the ten-day period is deemed to be Landlord's denial of the
     proposal.

     If Landlord's consent to the transfer, sublease or assignment is required
     pursuant to this paragraph 9, Landlord shall have the right, by giving
     written notice to tenant ten (10) business days after receipt of Tenant's
     notice, to terminate this Lease as to the portion of the Premises described
     in Tenant's notice. Such notice shall, if given, terminate this Lease with
     respect to the portion of the premises described in Tenant's notice as of
     the date stated in Tenant's notice.

     If this Lease terminates pursuant to the foregoing with respect to less
     than all of the Premises, the rent shall be prorated to that date. If




                                       13
<PAGE>   16
     Tenant proposes to sublet only a portion of the Premises, and Landlord
     exercises its right to recapture that portion, the effective date of
     recapture by Landlord shall be the effective date of the proposed
     subletting. On such date:

        (i)     that portion shall not be part of the Premises;

        (ii)    the Base Rent payable under this Lease shall be reduced by the
                rate per rentable square foot payable for such portion
                multiplied by the number of rentable square feet in such
                portion; the rental rate per rentable square foot is as follows:

                1st year        $18.50 per Rentable Square Foot
                2nd year        $19.00 per Rentable Square Foot
                3rd year        $19.50 per Rentable Square Foot
                4th year        $20.00 per Rentable Square Foot
                5th year        $20.50 per Rentable Square Foot
                6th year        $21.00 per Rentable Square Foot
                7th year        $21.50 per Rentable Square Foot

                The rate per rentable square foot shall be calculated according 
                to BOMA Standards for a single tenant building as that phrase 
                is defined in the Standard Method for Measuring Floor Area in 
                Office Buildings (an American National Standard ANSI/BOMA 265.1 
                1996 (Revised and readapted June 7, 1996) published by Building 
                Owners & Managers Association International;

        (iii)   Tenant's share of operating costs and real estate taxes shall 
                be reduced proportionately; and

        (iv)    Landlord shall, at its sole cost and expense, do all that is 
                necessary to separate the remainder of the Premises from the 
                portion recaptured by Landlord.

     If Tenant requests the right to sublet a portion of the Premises and the
     proposed sublease is for less than the remaining Term of the Lease and if
     the Landlord elects to exercise its rights of recapture, as described
     above, then at the end of the sublessee's term, the Tenant shall take back
     possession of the subleased portion of the Premises for the remainder of
     the then current Term of this Lease, as renewed, if applicable. When Tenant
     regains possession of the sublessee's portion of the Premises, Tenant shall
     be subject to all the terms of this Lease and shall pay rent at the rate
     provided in this Lease, even if the rent paid by the sublessee was greater
     than the Rent required by this Lease. Landlord and Tenant shall execute an
     amendment to this Lease to revive the Lease for the sublet portion of the
     Premises being returned for the balance of the then current Term. The
     rights to renewal shall be as provided in paragraph 42.

     (d)   As a condition to Landlord's written consent and to any subleasing,
     or assignment, assignees or the subtenants shall agree in writing to 



                                       14
<PAGE>   17

     comply with and be bound by all of the terms, covenants, conditions,
     provisions, and agreements of this Lease. Tenant shall deliver to Landlord,
     an executed copy of each assignment and sublease and an agreement to comply
     with the terms of the Lease signed by each assignee or sublessee.

     (e)  Landlord's consent to any sale, assignment, encumbrance, subletting,
     occupation, lien or other transfer shall not release Tenant from any of
     Tenant's obligations hereunder, except as agreed in writing by Landlord, or
     be deemed to be a consent to any subsequent occurrence. Any sale,
     assignment, encumbrance, subletting, occupation, lien or other transfer of
     this Lease which does not substantially comply with the provision of this
     Paragraph shall be void.

     (f)  The liability of the Tenant named in this Lease and any immediate or
     remote successor in interest of Tenant (by assignment or sublease), and the
     due performance of the obligations of this Lease on Tenant's part to be
     performed or observed, shall not in any way be discharged, released, or
     impaired by any (i) agreement which modifies any of the rights or
     obligations of the parties under the Lease, (ii) stipulation that extends
     the time with which an obligation under the Lease is to be performed, (iii)
     waiver of the performance of an obligation required under this Lease, or
     (iv) failure to enforce any of the obligations set forth in the Lease.
     Landlord shall use its best efforts to notify Tenant if any of the above
     enumerated actions would substantially increase Tenant's liability.

     (g)  If Landlord elects to allow Tenant to assign or sublet all or any
     portion of the Premises, and the sublease rent paid by the assignee or
     sublessee for the Premises or the portion thereof being assigned or sublet
     exceeds one hundred percent (100%) of the Rent provided by this Lease, (the
     "Excess Subrent"), if the Landlord does not exercise his right to recapture
     the space as provided herein, then such Excess Subrent shall be shared
     equally between Tenant and Landlord. Such party's pro rata share of the
     Excess Subrent shall be paid to the party within fifteen (15) business days
     of receipt by the other party.

     (h)  Without limiting any of the provisions of this paragraph, if Tenant
     has entered into any sublease of any portion of the Premises, the voluntary
     or other surrender of this Lease by Tenant, or a mutual cancellation by
     Landlord and Tenant, shall not work a merger (unless Landlord at its option
     by notice to the subtenant elects a merger to occur) and shall not
     terminate all or any subleases or subtenancies, but shall, at the option of
     the Landlord, operate as an assignment to Landlord of any or all such
     subleases or subtenancies.

10.  INSURANCE AND INDEMNIFICATION.

     (a)  Tenant shall purchase at its own expense and keep in force during the
     term of this Lease a policy or policies of workman's compensation and
     commercial general liability insurance, including personal injury and
     property damage, in the amount of no less than Two Million Dollars
     ($2,000,000) for property damage and Two Million Dollars ($2,000,000) 



                                       15
<PAGE>   18
     per claim for personal injuries or death of persons occurring in or about
     the Premises, or such other amount as Landlord shall reasonably deem
     necessary, based on periodic insurance reviews in respect to injury or
     damage to persons or property. Said policies shall: (i) name Landlord as an
     additional insured and insure Landlord's contingent liability under the
     Lease, (ii) be issued by an insurance company which is acceptable to
     Landlord and licensed to do business in the State of Washington, and, (iii)
     provide that such insurance shall not be canceled unless thirty (30) days
     prior written notice shall have been given to Landlord. Certificates of
     said policies shall be delivered to Landlord by Tenant on the Commencement
     Date and upon each renewal of said insurance.

     (b)  If Tenant serves, distributes or sells any alcoholic beverages, the
     insurance carried by Tenant shall not exclude violation of any governmental
     statute, ordinance, regulation or rule pertaining to the sale, gift,
     distribution or use of any alcoholic beverages and shall extend coverage
     for any damages occurring at locations other than the Premises and
     resulting from risks insurable by Host liquor license liability insurance.

     (c)  In addition to the insurance required above, Tenant shall, at its own
     cost and expenses, keep and maintain in full force and effect during the
     term, property insurance covering Tenant's supplies, inventory and other
     personal property as well as all improvements, additions and modifications
     to the Premises in an amount equal to one hundred percent of the
     replacement cost. The insurance policy shall bear an endorsement that the
     policy shall not be cancelled or the policy limits reduced below the
     coverage required by this Lease for any reason other than non-payment of
     premiums, except upon thirty (30) days prior written notice to Landlord.
     Tenant shall deliver certificates of said policies to Landlord upon the
     Commencement Date and upon each renewal of said insurance.

     (d)  If Tenant fails or refuses to maintain any insurance required herein,
     Landlord may at its discretion, obtain and maintain insurance for such
     items of interest to protect Landlord in such amounts as Landlord
     determines to be appropriate and all premiums paid or payable by Landlord
     shall be deemed to be Additional Rent and payable by Tenant as provided in
     Paragraph 3 of this Lease for the payment of Rent. Failure to obtain and
     maintain insurance required by this paragraph after twenty (20) days'
     written notice by Landlord to Tenant of such failure shall constitute a
     material breach of this Lease.

     (e)  Landlord shall not be liable to Tenant and Tenant hereby waives all
     claims against Landlord for any injury or damage to any person or property
     in or about the Premises by or from any cause whatsoever, other than
     Landlord's negligence or willful acts or omissions or the gross negligence
     or willful acts or omissions of Landlord's agents or employees. Landlord
     shall during the term maintain such insurance as Landlord deems necessary
     including replacement cost standard form property insurance and liability
     insurance and shall make Tenant an 



                                       16
<PAGE>   19
      additional insured under the liability insurance and provide Tenant
      certificates of insurance, upon request.

      (f) Tenant shall indemnify, defend and hold Landlord harmless from and
      against any and all claims and liability, including any claims brought by
      employees under any workman's compensation statute, for any injury or
      damage to any person or property whatsoever occurring in, on, or about the
      Premises, or any part thereof when such injury or damage is caused in part
      or in whole by the act, neglect, fault, or omission of Tenant or Tenant's
      officers, contractors, licensees, agents, servants, employees, guests,
      invitees, or visitors on or about the Premises. Tenant further agrees to
      indemnify and hold Landlord harmless against and from any and all claims
      by or on behalf of any person, firm or corporation arising from the
      conduct or management of any work or thing whatsoever done by the Tenant
      in or about the Premises or from the transactions of the Tenant concerning
      the Premises, and will further indemnify and hold Landlord harmless
      against and from any and all claims arising from any breach or default on
      the part of the Tenant in the performance of any covenant or agreement of
      this Lease on the part of Tenant, or any of its officers, contractors,
      licensees, agents, servants, employees, guests, invitees, or visitors on
      or about the Premises together with all costs, reasonable attorneys' fees,
      expenses, and liabilities incurred in connection with any such claim or
      action or proceeding brought thereon. If any action or proceeding is
      brought against Landlord by reason of any claim or liability, Tenant
      agrees to defend such action or proceeding at Tenant's sole expense by
      counsel selected by Tenant and reasonably satisfactory to Landlord. The
      provisions of this Paragraph shall survive the expiration or termination
      of the Lease with respect to any claims or liability occurring prior to
      such expiration or termination for a period ending five years after the
      Termination Date of this Lease.

      (g) Landlord shall indemnify, defend and hold Tenant harmless from and
      against any and all claims and liability for any injury or damage to any
      person or property whatsoever occurring in, on or about the Premises or
      any part thereof when such injury or damage is caused by the negligence or
      willful misconduct of Landlord or the gross negligence or willful
      misconduct of Landlord's employees or agents on or about the Premises.
      Landlord further agrees to indemnify and hold Tenant harmless against and
      from any and all claims by or on behalf of any person, firm or corporation
      arising solely from the conduct of any work done by the Landlord in or
      about the Premises, and will further indemnify and hold Tenant harmless
      against and from any and all claims arising from any breach or fault on
      the part of the Landlord in the performance of any covenant or agreement
      of this Lease on the part of Landlord, and all costs, reasonable
      attorneys' fees, expenses, and liabilities incurred in connection with any
      such claim or action or proceeding brought thereon. If any action or
      proceeding is brought against Tenant by reason of any claim or liability,
      Landlord agrees to defend such action or proceeding at Landlord's sole
      expense by counsel selected by Landlord and reasonably satisfactory to
      Tenant. The provisions of this paragraph shall survive the expiration or



                                       17
<PAGE>   20
      termination of the Lease with respect to any claims or liability occurring
      prior to such expiration or termination for a period ending five years
      after the Termination Date of this Lease.

11.   WAIVER OF SUBROGATION.

      Landlord and Tenant hereby waive any right that each may have against the 
      other on account of any loss or damage arising in any manner which is 
      covered by policies of insurance for fire and extended coverage, theft, 
      public liability, workmen's compensation or other insurance now or 
      hereafter existing during the term hereof, provided, however, the parties 
      hereby covenant with each other that no insurer shall hold any right of 
      subrogation against either Landlord or Tenant, as the case may be. 
      Nothing in this paragraph shall be interpreted to have the effect of 
      relieving or modifying any obligation of any insurance company, and shall 
      be void to the extent it would have such effect.

12.   SERVICES TO LANDLORD.

      Landlord shall pay as part of Basic Operating Costs, all charges for
      water, gas, heat, electricity, power, telephone service, sewer service and
      sewer rentals charged or attributable to the Premises, and all other
      services or utilities used in, upon or about the Premises during the Term
      and the cost of installing meters or check meters. Such amounts shall be
      billed by Landlord to Tenant at the time and in the manner Basic Operating
      Costs are billed and Tenant shall pay to Landlord as Additional Rent all
      such costs, expenses and charges so billed. Tenant shall not at any time
      overburden or exceed the capacity of the mains, feeders, ducts, conduits
      or other facilities by which utilities are supplied, distributed or
      serving the Premises. In no event shall Landlord be liable for an
      interruption or failure in the supply of any such utilities to the
      Premises and the same shall not constitute a termination of this Lease or
      eviction of Tenant except Tenant shall have the right to abatement
      described in paragraph 6(c) herein.

13.   ESTOPPEL CERTIFICATE.

      (a) Within ten (10) days following any written request which Landlord may 
      make from time to time, Tenant shall execute and deliver to Landlord a 
      certificate substantially in the form attached hereto as Exhibit "C" and 
      made a part hereof, indicating thereon any exceptions thereto which may 
      exist at that time. Failure of the Tenant to execute and deliver such 
      certificate within ten (10) days of notice that such certificate is 
      overdue shall constitute a material default under the terms of this Lease 
      and an acknowledgment by Tenant that the statements included in Exhibit 
      "C" are true and correct without exception. Landlord and Tenant intend 
      that any statement delivered pursuant to this Paragraph may be relied 
      upon by any mortgagee, beneficiary, purchaser or prospective purchaser of 
      the Premises or any interest therein.



                                       18

<PAGE>   21
     (b)  Within ten (10) days following any written request from Landlord,
     Tenant shall furnish its most recently publicly published financial
     statements to Landlord.

14.  HOLDING OVER.

     (a)  Any holding over after the expiration of the Term with the written
     consent of the Landlord of this Lease shall be a tenancy from month to
     month. The terms, covenants and conditions of such tenancy shall be the
     same as provided herein and the monthly Base Rent shall be one hundred
     fifty percent (150%) of the Base Rent paid monthly for the last month prior
     to the expiration, plus the monthly portion of Tenant's Proportionate Share
     of Basic Operating Costs. Acceptance by Landlord of Rent after such
     expiration shall not result in any other tenancy or any renewal of the
     Term, and the provisions of this paragraph are in addition to and do not
     affect Landlord's right of re-entry or other rights provided under this
     Lease or by applicable law.

     (b)  If Tenant shall retain possession of the Premises or any part
     therefore without Landlord's consent following the expiration or sooner
     termination of this Lease for any reason, then Tenant shall pay to Landlord
     for each day of such retention as Base Rent two hundred percent (200%) of
     the amount of the daily Base Rent for the last month prior to the date of
     such expiration or termination plus a monthly portion of Tenant's
     Proportionate Share of Basic Operating Expenses. Tenant shall also
     indemnify and hold Landlord harmless from any loss or liability resulting
     from delay by Tenant in surrendering the Premises, including, without
     limitation, any claims made by any succeeding tenant founded on such delay.
     Acceptance of rent by Landlord following expiration or termination shall
     not constitute a renewal of this Lease, and nothing contained in this
     paragraph shall waive Landlord's right of re-entry or any other right.
     Tenant shall be only a Tenant at sufferance, whether or not Landlord
     accepts any rent from Tenant while Tenant is holding over without
     Landlord's written consent.

15.  SUBORDINATION.

     Without the necessity of any additional document being executed by Tenant
     for the purpose of effecting a subordination, this Lease shall be subject
     and subordinate at all times to the lien of any mortgage or deed of trust
     which may now exist or hereafter be executed in any amount for which said
     building, land, or Landlord's interest or estate in any of said items, is
     specified as security; provided however that Tenant's subordination to any
     lien arising after the date of this Lease (except only a subsequent lien
     which represents the conversion of the existing construction loan secured
     by the Premises to a permanent financing loan of approximately the same
     principal amount) is subject to receipt by Tenant of an executed
     nondisturbance agreement (in the form attached as Exhibit C or other form
     acceptable to Tenant) between Tenant and the person or entity seeking
     subordination of Tenant's interest. Such nondisturbance agreement is not
     effective unless and until Tenant signs the Estoppel Certificate required
     under paragraph 13. Landlord will use its best efforts to obtain a
     nondisturbance



                                       19
<PAGE>   22
     agreement in favor of Tenant from the holder of the permanent loan secured 
     by the Premises. Landlord shall also have the right to subordinate or 
     cause to be subordinated such liens to this Lease. In the event that any 
     mortgage or deed of trust is foreclosed or a conveyance in lieu of 
     foreclosure is made for any reason, Tenant shall, notwithstanding any 
     subordination, attorn to and become the Tenant of the successor in 
     interest to Landlord at the option of such successor in interest and 
     subject to the terms of a non-disturbance agreement, and thus the 
     successor in interest to Landlord shall respect Tenant's possession of the 
     Premises under the Lease. Tenant covenants and agrees to execute and 
     deliver, upon demand by Landlord and in the form reasonably requested by 
     Landlord, any additional documents evidencing the priority or 
     subordination of this Lease with respect to the lien of any such mortgage 
     or deed of trust.

16.  RULES AND REGULATIONS.

     Tenant shall faithfully observe and comply with the rules and regulations 
     printed on or annexed to this Lease as Exhibit "D" and all reasonable 
     modifications thereof and additions thereto from time to time put into 
     effect by Landlord to the extent such rules and regulations are not 
     inconsistent with the terms of this Lease or contrary to Laws, do not 
     interfere with Tenant's operations, are not discriminatory, and do not 
     substantially increase the costs of Tenant to comply.

17.  RE-ENTRY BY LANDLORD.

     Landlord reserves and shall at all times have the right to re-enter the
     Premises to inspect the same, after reasonable prior notice to Tenant, to
     supply janitor service and any other service to be provided by Landlord to
     Tenant hereunder, to show said Premises to prospective purchasers or
     mortgagees or to show said Premises to prospective tenants during the last
     six (6) months of the term, to post notice of non-responsibility, and to
     alter, improve, or repair the Premises and any portion of the Premises,
     without abatement of Rent, (except as provided in paragraph 6(c)) and may
     for that purpose erect, use, and maintain scaffolding, pipes, conduit, and
     other necessary structures in and through the Premises where reasonably
     required by the character of the work to be performed, provided that
     entrance to the Premises shall not be blocked thereby, and further provided
     that the business of Tenant shall not be interfered with unreasonably or
     for prolonged periods of time. For each of the aforesaid purposes, Landlord
     shall at all times have and retain a key with which to unlock all of the
     doors in, upon, and about the Premises, excluding Tenant's vaults and
     safes, or special security areas (designated in advance by written notice
     to Landlord), and Landlord shall have the right to use any and all means
     which Landlord may deem necessary or proper to open said doors in an
     emergency, in order to obtain entry to any portion of the Premises. Any
     such emergency entry to the Premises, or portions thereof obtained by
     Landlord by any of said means, or otherwise, shall not under any
     circumstances be construed or deemed to be a forcible or unlawful entry



                                       20
<PAGE>   23
     into, or a detainer of, the Premises, or an eviction, actual or
     constructive, of Tenant from the Premises or any portions thereof.

18.  INSOLVENCY OR BANKRUPTCY.

     (a) If Tenant becomes a debtor under Chapter 7 of the Bankruptcy Code
     ("Code"), or if a petition for reorganization or adjustment of debts is
     filed concerning Tenant under Chapters 11 or 13 of the Code, or a
     proceeding is filed under Chapter 7 of the Code and is transferred to
     Chapters 11 or 13 of the Code, the Trustee or Tenant, and as
     debtor-in-possession, may not elect to assume this Lease unless, at the
     time of such assumption, the Trustee or Tenant has:

          (i)   cured all defaults under the Lease and paid all sums due and
                owing under the Lease, or provided Landlord with "adequate
                assurance" (as defined below) that (1) within ten (10) days from
                the date of such assumption, the Trustee or Tenant will
                completely pay all sums due and owing under this Lease and
                compensate Landlord for any actual pecuniary loss resulting from
                any existing defaults or breach of this Lease, including,
                without limitation, Landlord's reasonable costs, expenses,
                accrued interest, and attorney fees and costs incurred as a
                result of the default or breach and/or as a result of the filing
                of the petition in bankruptcy;

          (ii)  within twenty (20) days from the date of such assumption, the
                Trustee or Tenant will cure all non-monetary defaults and
                breaches under the Lease, or if the nature of such non-monetary
                defaults is such that more than twenty (20) days are reasonably
                required for such cure that the Trustee or Tenant will commence
                to cure such non-monetary defaults within twenty (20) days and
                thereafter diligently prosecute such cure to completion; and

          (iii) the assumption will be subject to all of the provisions of the
                Lease.

     (b) For purposes of this paragraph, Landlord and Tenant acknowledge that in
     the context of a bankruptcy proceeding involving Tenant, at a minimum,
     "adequate assurance" shall mean (i) that Trustee or Tenant has and will
     continue to have sufficient funds to fulfill the obligations of Tenant
     under this Lease; (ii) the Bankruptcy Court shall have entered an order
     segregating sufficient cash payable to Landlord and/or the Trustee or
     Tenant shall have granted a valid and perfected first lien and security
     interest and/or mortgage in or on the property of Trustee or Tenant
     acceptable as to value and kind to Landlord to secure to Landlord the
     obligation of the Trustee or Tenant to cure the monetary and/or
     non-monetary defaults and breaches under this Lease within the time period
     set forth above; and (iii) the Trustee or Tenant, at the very minimum,
     shall deposit a sum equal to two (2) months Base Rent to be held by
     Landlord (without any


                                       21
<PAGE>   24

      allowance for interest thereon) to secure Tenant's future performance 
      under the Lease.

     (c)  If the Trustee or Tenant has assumed the Lease pursuant to the 
     provisions of this paragraph for the purpose of assigning Tenant's 
     interests hereunder to any other person or entity, such interest may be 
     assigned only after the Trustee, Tenant, or the proposed assignee has 
     complied with all the terms, covenants, and conditions of this Lease, 
     including without limitation those with respect to additional rent. 
     Landlord and Tenant acknowledge that such terms, covenants and conditions 
     are commercially reasonable in the context of a bankruptcy proceeding by 
     Tenant. Any person or entity to which the Lease is assigned pursuant to 
     the provisions of the Code shall be deemed without further act or deed to 
     have assumed all of the obligations arising under this Lease on and after 
     the date of such assignment. Any such assignee shall, upon request, 
     execute and deliver to Landlord an instrument confirming such assignment.

     (d)  Upon the filing of a petition by or against Tenant under the Code, 
     Tenant, as debtor and debtor-in-possession, and any Trustee who may be 
     appointed, agree to adequately protect Landlord as follows: (i) to perform 
     each and every obligation of Tenant under this Lease until such time as 
     this Lease is either rejected or assumed by order of the Bankruptcy Court; 
     (ii) to pay all monetary obligations required under this Lease, including 
     without limitation the payment of Base Rent, Tenant's share of the 
     increase in Operating Costs, and any other sums payable by Tenant to 
     Landlord under this Lease which is considered reasonable compensation for 
     the use and occupancy of the Premises; (iii) provide Landlord a minimum of 
     thirty (30) days prior written notice, unless a shorter period is agreed 
     to by the parties, of any proceeding relating to any assumption of the 
     Lease or any intent to abandon the Premises, which abandonment shall be 
     deemed a rejection of the Lease; and (iv) to perform for the benefit of 
     the Landlord as required otherwise under the Code.

     Failure of Tenant to comply with the above shall result in automatic 
     rejection of the Lease.

19.  DEFAULT.

     A party's failure to perform or honor any covenant, condition or 
     representation made under this Lease shall constitute a default hereunder 
     by the party acting or failing to act upon the expiration of the 
     applicable cure period set forth in this Paragraph following written 
     notice of the default. If the default is failure to pay Rent, Additional 
     Rent, or other monetary sum, then the defaulting party shall have a 
     period of ten (10) days from the date of the notice to cure as provided by 
     statute. Except as otherwise provided in this Lease, a party shall have a 
     period of thirty (30) days from the date of the notice to cure any default 
     under this Lease that is not a default in payment of Rent or Additional 
     Rent; provided, however, that with respect to any default which cannot 
     reasonably be cured within thirty (30) days, the party in default shall 
     have additional time necessary to 


                                       22

<PAGE>   25

     cure the default so long as that party commences to cure within thirty 
     (30) days from the other party's notice, and continues to prosecute 
     diligently the curing thereof. Upon a default under this Lease by either 
     party following failure to cure by the defaulting party within the 
     permissible time period, the non-defaulting party, as specified  below 
     and after due process of law, shall have any or all of the following 
     rights and remedies in addition to, or as an alternative to, at the 
     non-defaulting party's option, any other rights or remedies available to 
     the non-defaulting party at law or in equity. All such rights and remedies 
     are cumulative:

     (a)  If Tenant is the defaulting party, the unpaid balance of any amounts 
     advanced by Landlord to Tenant for Tenant Improvements shall be 
     immediately due and payable without notice of acceleration. Landlord may 
     avail itself of all remedies available to collect said amounts, which are 
     deemed to be Additional Rent, including commencing action for eviction 
     and/or exercising any and all other remedies available under this Lease or 
     in law and equity.

     (b)  If the Tenant is the defaulting party, the Lease may be terminated at 
     the option of Landlord by notice in writing to Tenant. If the Landlord 
     gives notice of termination, the Lease will be deemed terminated as of the 
     date specified in the notice and the Tenant shall have no further rights 
     or obligations under the Lease except as provided in this Paragraph 19, 
     which shall survive termination of the Lease.

     (c)  Unless the Lease is terminated as provided in subparagraph (b), the 
     Lease will continue in full force and effect, except Tenant's right to 
     possession of the Premises may be terminated at any time, at the option 
     of Landlord, by notice in writing to Tenant. If Landlord gives notice to 
     Tenant as herein provided, Tenant's right to possession of the Premises 
     will be deemed terminated as of the date specified in Landlord's notice, 
     and Landlord may from time to time, but shall not be obligated to, sublet 
     the Premises or any part thereof for such term or terms and at such rent 
     and such other terms as is commercially reasonable, with the right to make 
     alterations and repairs to the Premises. Upon each subletting, at the 
     option of Landlord: (i) either Tenant shall be immediately liable to pay 
     to Landlord, in addition to indebtedness other than rent due hereunder, 
     the cost of such subletting and such alterations and repairs incurred by 
     Landlord and the amount, if any, by which the rent received for the period 
     of such subletting is less than the amount to be paid as rent for the 
     Premises for such period, or (ii) Landlord shall apply rents received from 
     such subletting first, to payment of any indebtedness other than rent due 
     hereunder from Tenant to Landlord; second, to the payment of any costs of 
     subletting and of any alterations and repairs; third, to payment of rent 
     due and unpaid hereunder; and the residue, if any, shall be held by 
     Landlord and applied in payment of future rent as the same becomes due 
     hereunder. If, under option (i), the rent shall not be promptly paid to 
     Landlord by the subtenant(s), or if, under option (ii), the rentals 
     received from the subletting during any month are less than all amounts
     owed for that month by Tenant hereunder, Tenant shall pay any 


                                       23
<PAGE>   26
     such deficiency to Landlord. Such deficiency shall be calculated and paid
     monthly.

     Unless and until the Lease is terminated as provided in subparagraph (b),
     Tenant shall continue to be liable to Landlord for rent and all other
     amounts owing under the Lease when and as they become due, whether or not
     Tenant's possession of the Premises has been terminated, and whether or not
     the Premises are sublet by Landlord. No act or omission by Landlord shall
     be construed as an election on its part to terminate this Lease unless a
     written notice of such intention is given to Tenant as provided in
     subparagraph (b). Notwithstanding any action taken by Landlord under this
     subparagraph, Landlord may at any time thereafter elect to terminate this
     Lease for such previous uncured or continuing breach.

     (d) Upon termination of the Lease as provided in subparagraph (b) and/or
     upon termination of Tenant's right to possession of the Premises, as
     provided in subparagraph (c), Landlord may re-enter and take possession of
     the Premises, and may remove any persons or property by legal action or any
     other lawful means and without liability for damages. Any of Tenant's
     property remaining on the Premises, including, without limitation,
     equipment, inventory, furnishings and trade fixtures, shall be deemed to
     have been abandoned by Tenant, upon five (5) days written notice to Tenant,
     and shall be and become the property of Landlord; provided, however, that
     Landlord may, in its sole discretion, reject the property and elect instead
     to store such property in a public warehouse or elsewhere at the cost of
     and for the account of Tenant, and further may, but shall not be obligated
     to, upon five (5) days written notice to Tenant, sell such property and
     apply the proceeds therefrom in accordance with applicable law.

     (e) In the event the Lease is terminated as provided in subparagraph (b)
     above, Landlord shall be entitled to recover immediately, without waiting
     until the due date of any future Rent or until the date fixed for
     expiration of the Term provided in the Lease, all of the following amounts
     as damages:

          (1) All past due Rent and other amounts owing by Tenant to Landlord
     pursuant to the terms of this Lease as of the date of termination of the
     Lease; and

          (2) All costs associated with Tenant's default, whether or not suit
     was commenced, including, without limitation, costs of re-entry and
     re-letting, costs of clean-up, refurbishing, removal of Tenant's property
     and fixtures, other expenses occasioned by Tenant's failure to quit the
     Premises upon termination and to leave them in the required condition, any
     remodeling costs, reasonable attorneys fees, court costs, broker
     commissions, and advertising costs; and

          (3) The loss of the reasonable rental value of the Premises from the
     date of termination of the Lease until a new Tenant has been, or with the
     exercise of reasonable efforts, could have been secured; and


                                       24
<PAGE>   27
          (4) Any excess of the value of the rent and all of Tenant's other
     obligations under this Lease, as if the Lease had not been terminated, over
     the reasonable expected return from the Premises for the period commencing
     on the earlier of the date of trial or the date of the Premises are relet
     and continuing through the end of the term. The present value of future
     amounts will be computed using a discount rate equal to the lowest prime
     interest rate announced by a major Washington bank on short-term commercial
     loans for its most credit-worthy customers, in effect on the date of trial
     or the date the Premises are relet. Landlord is entitled to all said
     amounts to the extent they are required to make Landlord whole together
     with double damages as provided by law.

     (f) Landlord may, in its sole discretion, sue periodically to recover
     damages during the period corresponding with the remainder of the Term, if
     the Lease has not been terminated. No action for damages shall bar a later
     action for damages subsequently accruing or, in the alternative, Landlord
     may elect to call the entire amount of rental for the balance of the term,
     or what would have been the balance of the term if the Lease had not been
     terminated as provided in subparagraph (b), immediately due and payable,
     which rent shall be paid by Tenant to Landlord as liquidated damages.

     (g) To the extent required by law, both Landlord and Tenant have the
     obligation to take reasonable steps to mitigate their damages caused by any
     default under this Lease.

20.  DAMAGE BY FIRE, ETC.

     (a) If the Premises are damaged or destroyed by fire or other casualty such
     that the repairs can be made within one hundred fifty (150) days from the
     date of such damage, then Landlord shall forthwith repair the same to the
     condition that existed on the date of the damage, under the laws and
     regulations of the federal, state, and local governmental authorities
     having jurisdiction thereof. In such event, this Lease shall remain in full
     force and effect except that Tenant shall be entitled to a proportionate
     abatement of rent while such repairs to be made hereunder by Landlord are
     being made. Said proportionate abatement shall be based on the rental rates
     per rentable square foot in Paragraph 9(c) above, and the extent to which
     the making of such repairs to be made hereunder by Landlord shall interfere
     with the business carried on by Tenant on the Premises. If such damages or
     destruction resulted from the act, fault or neglect of Tenant, then rent
     shall abate only to the extent Landlord receives proceeds from Landlord's
     rental income insurance policy to compensate Landlord for the loss of such
     rent.

     Within thirty (30) days from the date of such damage, Landlord shall notify
     Tenant whether or not such repairs can be made within one hundred fifty
     (150) days from the date of such damage. If and to the extent such damage
     or destruction is not fully covered by Landlord's insurance policy,
     Landlord shall have the right to terminate this Lease upon written notice
     of such election to terminate within thirty (30)


                                       25
<PAGE>   28
     days from the date of such damage or destruction. If the Landlord
     determines that such repairs cannot be made within one hundred fifty (150)
     days from the date of such damage or destruction, then Landlord shall have
     the option within thirty (30) days of the date of such damage or
     destruction either to: (a) notify Tenant of Landlord's intention to repair
     the damage, in which event this Lease shall continue in full force and
     effect and the Rent shall be reduced as provided herein; or (b) notify
     Tenant of Landlord's intention to terminate this Lease as of the date
     specified in such notice which date shall be not less than thirty (30) days
     nor more than sixty (60) days after such notice is given. In case of
     termination of the Lease by Landlord, (i) the rent shall be partially
     abated by a proportionate amount based upon the rental rates per rentable
     square foot in Paragraph 9(c) above, and the extent to which said damage
     interfered with the business carried on by Tenant in the Premises, and the
     Tenant shall pay such reduced rent up to the date of termination specified
     in Landlord's notice; and (ii) the unused Security Deposit and unearned
     rent paid by the Tenant under this Lease shall be returned to Tenant
     immediately upon such termination. The repairs to be made hereunder by
     Landlord shall not include, and Landlord shall not be required to repair,
     any damage by fire or other cause to Tenant's Personal Property or any
     repairs or replacements of any paneling, decorations, railings, floor
     coverings, or any alterations, additions, fixtures or improvements
     installed on the Premises by or at the expense of Tenant.

     If Landlord determines that the repairs cannot be made within one hundred
     fifty (150) days and elects to terminate the Lease, Tenant may request that
     Landlord's determination be reviewed by a Repair Architect. If the parties
     cannot agree on a selection of a Repair Architect within ten (10) days
     following Tenant's written notice to Landlord that it wishes a Repair
     Architect to settle the matter, both Tenant and Landlord shall appoint a
     Repair Architect within five (5) days who shall in turn select a third
     Repair Architect. The decision of the third Repair Architect shall be
     rendered within thirty (30) days from the date he is appointed and shall be
     binding upon the parties. The matter shall not be submitted to a Repair
     Architect if Landlord's insurance would not cover the required repairs. If
     the Repair Architect determines that the repairs cannot be made within one
     hundred fifty (150) days, then the Lease shall be terminated as of the date
     the decision of the Repair Architect is rendered. The parties shall share
     equally the cost of the Repair Architect.

     (b) If at the time of any such damage, less than one (1) year remains in
     the Term and Tenant has not exercised its option to extend the Term then
     either Landlord or Tenant, at either's sole option, shall have the right to
     terminate this Lease.

21.  EMINENT DOMAIN.

     (a)  If any part of the Premises shall be taken or appropriated under the
     power of eminent domain or conveyed in lieu thereof and said taking
     materially interferes with Tenant's business or Landlord's ability to Lease
     the Premises, Landlord shall have the right to terminate this 



                                       26


<PAGE>   29
     Lease. In such event, Landlord shall receive, and Tenant shall assign to
     Landlord upon demand from Landlord, any and all income, rent, award or any
     interest thereon which may be paid or owed in connection with the exercise
     of such power of eminent domain or conveyance in lieu thereof. Tenant shall
     have no claim against Landlord or against the agency exercising such power
     or receiving such conveyance, for any part of such sum paid by virtue of
     such proceedings. Notwithstanding the foregoing, Tenant may pursue its
     remedies against the condemning agency for the value of the unexpired Term,
     and for reimbursement for the value of its personal property, moving and
     relocation expenses and value of improvements made to the Premises at
     Tenant's expense after the Commencement Date so long as said action does
     not act to diminish Landlord's recovery of its loss.

     If a part of the Premises shall be so taken or appropriated or conveyed and
     Landlord shall elect not to terminate this Lease, Landlord shall
     nonetheless receive (and Tenant shall assign to Landlord upon demand from
     Landlord) any and all income, rent, award or any interest thereon paid or
     owed in connection with such taking, appropriation or conveyance. If the
     Premises have been damaged as a consequence of such partial taking or
     appropriation or conveyance, Landlord shall restore the Premises continuing
     under this Lease at Landlord's cost and expense provided that such
     restoration can be made within one hundred fifty (150) days of the time the
     property so taken is appropriated or conveyed. If restoration cannot be
     made within one hundred fifty (150) days from the time of taking, Landlord
     shall notify Tenant within sixty (60) days of such taking and Landlord or
     Tenant shall have the right to cancel this Lease by giving the other
     written notice of its intention to cancel within thirty (30) days of the
     date of Landlord's notice.

     If Landlord determines that the repairs cannot be made within one hundred
     fifty (150) days and elects to terminate the Lease, Tenant may request that
     Landlord's determination be reviewed by a Repair Architect. If the parties
     cannot agree on the selection of a Repair Architect within ten (10) days
     following Tenant's written notice to Landlord that it wishes a Repair
     Architect to settle the matter, both Tenant and Landlord shall appoint a
     Repair Architect within five (5) days who shall in turn select a third
     party Architect. The decision of the third Repair Architect shall be
     rendered within thirty (30) days from the date he is appointed and shall be
     binding upon the parties. The matter shall not be submitted to a Repair
     Architect if Landlord's insurance would not cover the required repairs. If
     the Repair Architect determines that the Lease can be terminated as decided
     by the Landlord, the Lease shall be terminated as of the date the decision
     of the Repair Architect is rendered. The parties shall share equally the
     cost of the Repair Architect.

     (b)  If Landlord and/or Tenant elect not to cancel this Lease, it shall
     remain in full force and effect except that Tenant shall be entitled to a
     proportionate abatement in Rent while restoration is being made by
     Landlord. Such proportionate abatement shall be based upon the rental rates
     per rentable square foot in Paragraph 9(c) above, and the extent to which
     the taking, appropriation or conveyance and the restoration




                                       27
<PAGE>   30
     being made by Landlord interferes with the business operations carried on 
     by Tenant in the Premises. Landlord will not be required to repair or 
     restore any injury or damage to Tenant's Personal Property or make any 
     repairs or restoration to any alterations, additions, fixtures or 
     improvements installed in the Premises by or at the expense of Tenant.

     (c)  Notwithstanding anything to the contrary contained in this paragraph, 
     if the temporary use or occupancy of any part of the Premises is taken or 
     appropriated under power of eminent domain during the Term and such 
     temporary use or occupancy continues for one hundred fifty (150) days or 
     less and does not materially interfere with Tenant's ability to continue 
     to operate its business at the Premises, this Lease shall be and remain 
     unaffected by the taking or appropriation and Tenant shall continue to pay 
     in full all Rent payable hereunder by Tenant during the Term. In the event 
     of any temporary appropriation or taking, Tenant shall be entitled to 
     receive that portion of any award which represents compensation for the 
     use or occupancy of the Premises during the term of this Lease, and 
     Landlord shall be entitled to receive that portion of any award which 
     represents the cost of restoration of the Premises and the use and 
     occupancy of the Premises after the end of the term of this Lease.

22.  SALE BY LANDLORD.

     In the event of a sale or conveyance by Landlord of the Premises, the same 
     shall operate to release Landlord from any future liability upon any of 
     the covenants or conditions, express or implied, herein contained in favor 
     of Tenant and becoming due or arising thereafter, and in such event Tenant 
     agrees to look solely to the responsibility of the successor in interest 
     of Landlord in and to this Lease as to any liability becoming due or 
     arising thereafter. If Landlord transfers the Security Deposit and other 
     deposits held to its successor, Tenant hereby releases Landlord from 
     liability for all deposits paid by Tenant and released by Landlord to 
     Landlord's successor. This Lease shall not be affected by any such sale, 
     and Tenant agrees to attorn to the purchaser or assignee. As a material 
     consideration for entering into this Lease, Landlord agrees not to sell or 
     convey the Premises or assign Landlord's interest in this Lease before 
     Tenant takes possession of the Premises.

23.  RIGHT OF LANDLORD TO PERFORM.

     All covenants and agreements to be performed by Tenant under any of the
     terms of this Lease shall be performed by Tenant at Tenant's sole cost and 
     expense and, without any abatement of rent, except as otherwise provided 
     in this Lease. If Tenant shall fail to pay any sum of money, other than 
     Rent or Additional Rent, required to be paid by it hereunder or shall fail 
     to perform any other act on its part to be performed hereunder, and such 
     failure shall continue after expiration of the notice period required by 
     the Lease, if any, Landlord may, but shall not be obligated to do, and 
     without waiving or releasing Tenant from any obligations of Tenant, to 
     make any such payment or perform any such act on Tenant's part to be made 
     or performed as in this Lease provided.



                                       28
<PAGE>   31
     All sums so paid by Landlord and all necessary incidental costs (together 
     with interest thereon at the rate of twelve percent (12%) per annum or 
     four percent (4%) above the prime rate of US Bank per annum, whichever is 
     more, from the date of such payment by Landlord, and shall be payable as 
     Additional Rent to Landlord on demand, and Tenant covenants to pay any 
     such sums. Landlord shall have, in addition to any other right or remedy 
     of Landlord, the same rights and remedies in the event of nonpayment 
     thereof by Tenant as in the case of default by Tenant in the payment of 
     the Rent.

24.  SURRENDER OF PREMISES.

     (a)  At the end of the Term (as it may be extended) or other sooner 
     termination of this Lease, or upon termination of Tenant's right to 
     possession, Tenant will peaceably deliver up to Landlord possession of the 
     Premises, together with all improvements or additions upon or belonging to 
     same, by whomsoever made, in the same condition as received or first 
     installed, ordinary wear and tear, damage by fire, earthquake, Act of God, 
     the elements, other casualty condemnation, or the negligence or willful 
     misconduct of Landlord, or the gross negligence or willful misconduct of 
     Landlord's agents or employees excepted. Tenant may, prior to or upon the 
     termination of this Lease or termination of Tenant's right to possession, 
     remove any property or items which Tenant is entitled to remove under this 
     Lease, at Tenant's sole cost, repairing any material damage caused by such 
     removal. Property not so removed upon the termination of this Lease or 
     upon termination of Tenant's right to possession shall be deemed abandoned 
     by Tenant, and title to the same shall thereupon pass to Landlord. Upon 
     request by Landlord, unless otherwise agreed to in writing by Landlord, 
     Tenant shall remove, at Tenant's sole cost, any or all permanent 
     improvements or additions to the Premises installed by or at the expense 
     of Tenant after Tenant took possession of the Premises or which were 
     designated by Landlord at the time of construction to be removed by Tenant 
     upon termination and all movable furniture and equipment belonging to 
     Tenant which are not Tenant Alterations. Tenant shall repair any material 
     damage resulting from such removal.

     (b)  At Landlord's option, the voluntary or other surrender of this Lease 
     by Tenant, or mutual cancellation thereof, shall not work a merger, and 
     shall operate as an assignment of any and all subleases or subtenancies.

25.  WAIVER.

     If either Landlord or Tenant waives the performance of any term, covenant 
     or condition contained in this Lease, such waiver shall not be deemed to 
     be a waiver of any subsequent breach of the same or any other term, 
     covenant or condition contained herein. Furthermore, the acceptance of 
     Rent by Landlord shall not constitute a waiver of any preceding breach by 
     Tenant of any term, covenant or condition of this Lease, regardless of 
     Landlord's knowledge of such preceding breach at the time Landlord 
     accepted such Rent. Failure by either party to enforce any of the terms, 
     covenants or conditions of this Lease for any



                                       29
<PAGE>   32
      length of time shall not be deemed to waive or to decrease the right of 
      either party to insist thereafter upon strict performance by the other 
      party. Waiver by either party or any term, covenant or condition 
      contained in this Lease may only be made by a written document signed by 
      the party waiving such term, covenant or condition.

26.   NOTICES.

      All notices, requests and demands which may be or are required to be 
      given by either party to the other hereunder shall be in writing. All 
      notices and demands by Landlord to Tenant shall be sent by United States 
      certified or registered mail, postage prepaid, or by overnight courier 
      service, addressed to Tenant at the Premises address, or to such other 
      place as Tenant may from time to time designate in a notice to Landlord,

      prepaid, addressed to Landlord at the address specified in the Basic 
      Lease Information, or to such other firm or to such other place as 
      Landlord may from time to time designate in a notice to Tenant. All

      delivered to the address designated above or on the date mailed as

      as Rent, Tenant's Proportionate Share of Basic Operating Costs in the

      than the entire building, then Tenant's Proportional Shares of Basic 
      Operating Costs shall be reduced by the percentage of the space in the

<PAGE>   35
          (2)  "Estimated Basic Operating Costs" for any particular Fiscal Year 
     shall mean Landlord's estimate of the Basic Operating Costs for such 
     Fiscal Year as hereinafter provided. Landlord shall have the right from 
     time to time to revise its Fiscal Year and interim accounting periods so 
     long as the periods as so revised are reconciled with prior periods in 
     accordance with generally accepted accounting principles consistently 
     applied.

          (3)  "Basic Operating Cost Adjustment" shall mean the difference 
     between Basic Operating Costs and Estimated Basic Operating Costs for any 
     Fiscal Year determined as hereinafter provided.

     (b)  Payment of Estimated Basic Operating Costs. During the last month of
     each Fiscal Year during the Term, or as soon thereafter as practicable,
     Landlord shall give Tenant written notice of the Estimated Basic Operating
     Costs for such Fiscal Year. The Fiscal Year is as specified in the Basic
     Lease Information. The Estimated Basic Operating Costs for the Fiscal Year
     in which the Commencement Date falls is set forth in the Basic Lease
     Information sheet. Tenant shall pay in advance one twelfth (1/12th) of one
     hundred percent (100%) of the Estimated Basic Operating Costs with each
     monthly installment of Basic Rent required to be paid pursuant to paragraph
     3 above for the Fiscal Year to which the estimate applies on the first day
     of each calendar month during such Fiscal Year. Such payment shall be
     construed to be Rent for all purposes hereof. If at any time during the
     course of a Fiscal Year, Landlord determines that Basic Operating Costs
     will materially vary from the then Estimated Basic Operating Costs, 
     Landlord may, by written notice to Tenant, revise the Estimated Basic 
     Operating Costs for the balance of such Fiscal Year and Tenant shall pay 
     Tenant's Proportionate Share of Estimated Basic Operating Costs as so 
     revised for the balance of the then current Fiscal Year on the first day 
     of each calendar month thereafter. Such revised installment amounts are 
     Rent for all purposes hereof. Failure to revise the amount paid shall not 
     diminish Landlord's right to collect all Basic Operating Costs from Tenant 
     as Additional Rent.

     (c)  Computation of Basic Operating Costs Adjustment. Within ninety (90) 
     days after the end of each Fiscal Year, or as soon after the end of the 
     Fiscal Year as practicable, Landlord shall deliver to Tenant a statement 
     of Basic Operating Costs for the Fiscal Year just ended, accompanied by a 
     computation of the Basic Operating Costs Adjustment. If such statement 
     shows that Tenant's payments of Estimated Basic Operating Costs is less 
     than Tenant's Proportionate Share of Basic Operating Costs, then Tenant 
     shall pay the difference within thirty (30) days after receipt of such 
     statement, such payment to constitute Additional Rent hereunder. If such 
     statement shows that Tenant's payments of Estimated Basic Operating Costs 
     exceed Tenant's Proportional Share of Basic Operating Costs, then 
     (provided that Tenant is not in default under this Lease) Landlord shall 
     so notify Tenant and reimburse Tenant for the overpayment within thirty 
     (30) days of notification to Tenant of the overpayment. If this Lease has

     statement, then the Basic Operating Costs Adjustment shall be paid by the
     appropriate party within twenty (20) days after the date of delivery of the
     statement.

     (d) Net Lease. This shall be a net Lease and Base Rent shall be paid to
     Landlord net of all costs and expenses of repairing, operating and
     maintaining the Premises. The provisions for payment of Basic Operating
     Costs by means of periodic payments of Tenant's Proportionate Share of
     Estimated Basic Operating Costs and the Basic Operating Costs Adjustment
     are intended to pass on to Tenant and reimburse Landlord for the costs and
     expenses of the nature described in Paragraph 27(a)(1) above incurred in
     connection with ownership and operation of the Premises now and in
     subsequent years as may reasonably be determined by Landlord to be
     necessary to the Premises.

     (e) Tenant Audit. Tenant shall have the right, at Tenant's expense and upon
     not less than seven (7) days prior written notice to Landlord, to review at
     reasonable times Landlord's books and records for any Fiscal Year, or
     portion of which that falls within the Term for the purposes of verifying
     Landlord's determination and calculation of Basic Operating Costs and Basic
     Operating Costs Adjustment. In the event that Tenant shall dispute the
     amount set forth in any statement provided by Landlord under paragraph
     27(c) above, Tenant shall have the right, not later than sixty (60) days
     following the receipt of such statement to cause Landlord's books and
     records with respect to such Fiscal Year to be audited by certified public
     accountants selected by Tenant subject to Landlord's reasonable right of
     approval as to selection of the accountants and upon condition that Tenant
     shall first deposit with Landlord the full amount in dispute. The Basic
     Operating Costs Adjustment shall be appropriately adjusted on the basis of
     such audit. If such audit discloses a liability for a refund or credit by
     Landlord to Tenant in excess of ten percent (10%) of Tenant's Proportionate
     Share of Basic Operating Costs Adjustment previously reported, the cost of
     such audit shall be borne by Landlord. Otherwise the cost of such audit
     shall be paid by Tenant. If Tenant shall not request an audit in accordance
     with the provisions of this subparagraph 27(e) within sixty (60) days of
     receipt of Landlord's statement provided pursuant to paragraph 27(c), such
     statement shall be final and binding for all purposes hereof. Any
     discrepancy revealed by an audit under this subparagraph shall be promptly
     paid by the party owing the money based on the results. Amounts not paid
     upon demand shall bear interest at the rate of twelve percent (12%) per
     annum or four percent (4%) above the prime rate of US Bank per annum,
     whichever is more, from five (5) days after the date of the demand until
     paid in full.

28.  TAXES PAYABLE BY TENANT.

     Landlord shall pay and Tenant shall reimburse Landlord for any and all
     installments of taxes levied or assessed and which become payable by
     Landlord (or Tenant) during the term of this Lease (excluding, however,
     state and federal personal or corporate income taxes measured by the income
     of Landlord from all sources, capital stock taxes, and estate and
     inheritance taxes and taxes levied on Tenant's personal property), whether
     or not now customary or within the contemplation of the parties hereto,
     which are based upon, measured by or otherwise calculated with respect to:
     (a) the gross or net payable under this Lease, including, without
     limitation, any gross receipts tax levied by any taxing authority, or any
     other gross income tax or excise tax levied by any taxing authority with
     respect to the receipt of the rental hereunder, (b) the value of Tenant's
     equipment, furniture, fixtures or other personal property located in the
     Premises; (c) the possession, lease, operation, management, maintenance,
     alteration, repair, use or occupancy by Tenant of the Premises or any
     portion thereof; (d) the value of any leasehold improvements, alterations
     or additions made in or to the Premises, regardless of whether title to
     such improvements, alterations or additions shall be in Tenant or Landlord;
     or (e) this transaction or any document to which Tenant is a party creating
     or transferring an interest or an estate in the Premises. All such taxes
     shall be estimated, collected and paid in the same manner as Basic
     Operating Costs.

     In the event that it shall not be lawful for Tenant to so reimburse
     Landlord, the Rent payable to Landlord under this Lease shall be revised to
     provide Landlord with the same net Rent after imposition of any such tax
     upon Landlord as would have been payable to Landlord prior to the
     imposition of any such tax. All taxes payable by Tenant under this
     paragraph shall be deemed to be and shall be paid as Additional Rent.

     Tenant shall pay directly to the taxing authority before any such taxes
     become delinquent all taxes levied on Tenant's income or personal property
     and all other taxes directly related to Tenant's assets and business
     operations; provided Tenant may contest any such tax in good faith without
     violating this provision.

29.  SUCCESSORS AND ASSIGNS.

     Subject to the provisions of Paragraph 9 hereof, the terms, covenants and
     conditions contained herein shall be binding upon and inure to the benefit
     of the heirs, successors, executors, administrators and assigns of the
     parties hereto.



                                       35
<PAGE>   38

30.  ATTORNEY'S FEES.

     In the event that it is necessary for either party to retain an attorney to
     enforce or interpret the terms of the Lease, the prevailing party shall be
     entitled to recover, in addition to damages proven, all reasonable attorney
     fees and costs incurred in enforcing this Lease, whether said fees and
     costs are incurred in negotiation, mediation, arbitration, litigation,
     appeal, bankruptcy, pre- or post-judgment collection, declaratory action,
     or otherwise. In the event of litigation, the prevailing party shall be
     determined by a court of competent jurisdiction.

31.  SECURITY DEPOSIT.

     (a) Upon execution of this Lease, Tenant will pay Landlord a Security
     Deposit for the faithful performance of all terms, covenants and conditions
     of this Lease. The sum of said deposit is specified in the Basic Lease
     Information. Tenant agrees that Landlord may apply said Security Deposit to
     remedy any failure by Tenant to repair or maintain the Premises or to
     perform any other terms, covenants or conditions contained herein. If
     Tenant has kept and performed all terms, covenants and conditions of this
     Lease during the term hereof, Landlord will, on the termination hereof
     promptly return said sum to Tenant or the last permitted assignee of
     Tenant's interest hereunder at the expiration of the Lease Term or any
     extended Lease Term. Should Landlord use any portion of said sum to cure
     any default by Tenant hereunder, Tenant shall forthwith replenish said sum
     to such original amount. Landlord shall not be required to keep any
     Security Deposit separate from its general funds, and Tenant shall not be
     entitled to interest on any such deposit. Upon the occurrence of any events
     of default described in Paragraph 19 of this Lease. After the expiration of
     any applicable cure period without cure having been accomplished, said
     Security Deposit shall become the property of Landlord. Landlord may
     increase the amount of the deposit each time Tenant exercises its option to
     renew so that Landlord always has an amount equal to the last month's Base
     Rent as a Security Deposit.

     (b)  Tenant hereby agrees not to look to the mortgagee, as mortgagee,
     mortgagee in possession, or successor in title to the property, for
     accountability for any Security Deposit required by the Landlord hereunder,
     unless said sums have actually been received by such mortgagee as security
     for the Tenant's performance of this Lease.

32.  SIGNAGE.

     Subject to Landlord's prior approval, which shall not be unreasonably
     withheld or delayed, Tenant shall have the right to install signage on or
     in the Premises at its own cost. The right to install signage on or in the
     Premises shall be exclusive to the Tenant at all times during which Tenant
     leases more than ninety percent (90%) of the Premises except for
     identification and location signs for the other Tenants on the building
     directory and office doors or walls. Such signage shall be in accordance
     with all applicable codes, rules and regulations.



                                       36
<PAGE>   39
     Tenant shall provide to Landlord detailed plans for the exterior signage,
     including colors, scale, placement, and all other elements related to the
     signage, prior to submitting the same to the municipality for approval.
     Tenant shall be responsible for acquiring and paying for all municipal
     approvals and permits. Tenant shall pay all costs incurred to obtain
     Landlord's approval including review and/or redesign by Landlord's
     architect or other agents. At the termination of the Lease, Tenant shall
     pay all costs for removing all signs and restoring the Premises to their
     condition at the time the sign was installed, reasonable wear and tear,
     damage from casualty or condemnation or Landlord's negligence or Landlord's
     employees and agents' gross negligence excepted.

33.  CORPORATE AUTHORITY.

     Each of the persons executing this Lease on behalf of Landlord or Tenant
     does hereby covenant and warrant pertaining to the entity for whom they
     sign that it is a duly authorized and existing corporation, that the
     corporation has and is qualified to do business in Washington, that the
     corporation has full right and authority to enter into this Lease, and that
     each and all of the persons signing on behalf of the corporation are
     authorized to do so. Upon a party's request, the other party shall provide
     evidence reasonably satisfactory to the requesting party confirming the
     foregoing covenants and warranties.

34.  LEASE EFFECTIVE DATE.

     Submission of this instrument for examination or signature by Tenant does
     not constitute a reservation of or option for Lease, and it is not
     effective as a Lease or otherwise until execution and delivery by both
     Landlord and Tenant.

35.  BROKERAGE FEES.

     Tenant hereby represents and warrants that it has not used or dealt with
     any other broker, agent or other person in connection with this
     transaction, except Colliers MacAuley Nichols International, and that
     Tenant owes no brokerage fees or commission related to this Lease. Tenant
     agrees to defend, indemnify and hold Landlord harmless from and against any
     claims or liens filed by any other broker, agent, or other person claiming
     a commission or other form of compensation by virtue of having dealt with
     Tenant with regard to this leasing transaction. Landlord shall pay
     commissions due to Colliers MacAuley Nichols International and Leibsohn and
     Company for this Lease pursuant to the Listing Agreement with Leibsohn and
     Company. Landlord shall have no obligation to pay commissions to any agent
     upon Tenant's exercise of any of its options to extend the term pursuant to
     this Lease or if Tenant should enter into a Lease for subsequent terms.




                                       37
<PAGE>   40
36.  FORCE MAJEURE.

     Whenever a period of time is herein prescribed for action to be taken by 
     either party, the party required to act shall not be liable or responsible 
     for, and there shall be excluded from the computation for any such period 
     of time, any delays due to strikes, riots, Acts of God, shortages of labor
     or materials, war, governmental laws, regulations or restrictions or any 
     other causes of any kind whatsoever which are beyond the reasonable 
     control of the party required to act. The Tenant's rights of self-help in 
     this Lease are available during periods of force majeure delay or 
     interruption so long as required notice is given.

37.  CHANGE IN BUILDING NAME.

     The name of the Building will be INTERLINQ PLAZA upon the execution of 
     this Lease for as long as Tenant leases the building, subject to Paragraph 
     38(b)(i) below.

38.  CERTAIN RIGHTS RESERVED BY LANDLORD

     Landlord shall have the following rights, exercisable without notice and 
     without liability to Tenant, for damage or injury to property, persons or 
     business and without effecting an eviction, constructive or actual, or 
     disturbance of Tenant's use or possession or giving rise to any claim for 
     setoff or abatement of rent if any other tenant occupies the building:

     (a)  Landlord may, at its option, decorate and make repairs, alterations, 
     additions, changes or improvements, whether structural or otherwise, in 
     and about the public areas and any subleased or assigned portions of the 
     Premises not occupied by Tenant or subject to repossession by Tenant under 
     paragraph 9(c), ("Unoccupied Areas"), or any part thereof, and for such 
     purposes, upon reasonable notice to Tenant, may enter upon the public 
     areas or Unoccupied Areas of the Premises. During the continuance of any 
     such work, Landlord may temporarily close doors or entryways in the public 
     or unoccupied areas of the building, interrupt or temporarily suspend 
     non-essential building services and facilities all without abatement of 
     rent, except as otherwise provided herein, and without affecting any of 
     Tenant's obligations hereunder, so long as the public areas of the 
     Premises are reasonably accessible and reasonably tenantable.

     (b)  If Tenant subleases or assigns any portion of the Premises or if 
     another tenant enters into occupancy of the Premises, Landlord may, upon 
     reasonable notice to Tenant, (i) change the name by which the Premises is 
     designated if Tenant occupies less than fifty one percent (51%) of the 
     Premises; (ii) grant to anyone the exclusive right to conduct any business 
     or render any service in or to the Unoccupied Areas of the Premises, 
     provided such exclusive right shall not operate to exclude Tenant from the 
     use expressly permitted herein; (iii) have access for Landlord and other 
     tenants of the Premises to any mail chutes located on the Premises 
     according to the rules of the United



                                       38
<PAGE>   41
     States Postal Service; (iv) take all such reasonable measures as Landlord 
     may deem advisable for the security of the Project and its occupants. Said 
     actions may be taken under such reasonable regulations as Landlord may 
     prescribe from time to time generally applied to all Tenants.

39.  PERSONAL LIABILITY.

     The liability of Landlord to Tenant for any default by Landlord under the
     terms of this Lease shall be limited to the interest of Landlord in the
     Premises, and Landlord shall not be personally liable for any deficiency.
     This clause shall not be deemed to limit or deny any remedies which Tenant
     may have in the event of default by Landlord hereunder which do not involve
     the personal liability of Landlord. No personal liability is assumed by,
     nor shall at any time be asserted or enforceable against Landlord or its
     principals on account of the Lease or on account of any covenant or
     agreement of Landlord contained herein. Tenant's sole and exclusive remedy
     shall be against Landlord's interest in the Premises and the land on which
     it is located. No principal of Landlord shall be served or named as a party
     in any suit or shall be required to answer or otherwise plead to any
     service of or process, and no judgment shall be entered against any
     principal of Landlord. Any judgment entered against any principal of
     Landlord may be vacated and set aside at any time nunc pro tunc.

40.  QUIET ENJOYMENT.

     Provided Tenant observes its obligations under this Lease, Tenant shall 
     have peaceable and quiet enjoyment of the Premises throughout the Term, 
     and Landlord shall not act in any manner which would interfere with or 
     disrupt Tenant's business or frustrate Tenant's business purposes at the 
     Premises.

41.  MISCELLANEOUS.

     (a)  The paragraph headings herein are for convenience of reference and
     shall in no way define, increase, limit or describe the scope or intent of
     any provision of this Lease. The term "Landlord" in these presents shall
     include the Landlord, its successors, and assigns. The term "Tenant" or any
     pronoun used in place thereof shall indicate and include the masculine or
     feminine, the singular or plural number, individuals, firms or
     corporations, and their and each of their respective successors, executors,
     administrators, and permitted assigns, according to the context hereof.

     (b)  Time is of the essence of this Lease and all its provisions. This
     Lease shall in all respects be governed by the laws of the State of
     Washington. This Lease, together with its exhibits, contains all the
     agreements of the parties hereto and supersedes any previous negotiations.
     The terms of this Lease supersede any representations made by the Landlord
     or understandings made between the parties other than those set forth in
     this Lease and its exhibits. This Lease may not be modified except by a
     written instrument by the parties hereto.



                                       39
<PAGE>   42
     
     (c)  If for any reason whatsoever any of the provisions hereof shall be 
     unenforceable or ineffective, all of the other provisions shall be and 
     remain in full force and effect.

42.  OPTION TO RENEW.

     Tenant shall have two (2) consecutive options to extend the Term for an 
     additional five (5) years each. Tenant must give Notice of its intent to 
     exercise an option to Landlord not less than nine (9) months, nor more 
     than one (1) year, prior to expiration of the then existing Term. The 
     Lease shall continue in full force and effect during the Term (as so 
     extended), except the Base Rent will be adjusted for each five year 
     extension of the Term and Landlord may increase the amount of the Security 
     Deposit as provided in paragraph 31 so that the Security Deposit always 
     equals the last month's Base Rent for the Term.

     Commencing no later than twenty (20) days after Tenant's Notice of intent 
     to exercise an option to extend, the parties shall attempt to agree upon 
     the amount of the Base Rent for the Premises for the applicable extension 
     of the Term. The Base Rent for the extension of the Term shall be equal to 
     ninety-five percent (95%) of the current market rental rates for 
     comparable space in comparable Class A buildings in comparable locations 
     in Bellevue, Redmond, Kirkland and Mercer Island. If the parties cannot 
     agree on the Base Rent for the extension of the Term within sixty (60) 
     days of the date Landlord receives Tenant's Notice of intent to exercise 
     the option to extend, then, at the election of either party, the Base Rent 
     for the extension of the Term shall be established by an MAI appraiser 
     jointly selected by the parties. The party who wishes to have the Base 
     Rent determined for the extended term must so notify the other in writing 
     and designate an MAI appraiser. Said designation must be received by the 
     other party within thirty (30) days of Tenant's notice of exercise of its 
     option to extend, or Tenant's option will automatically terminate. If the 
     parties are unable to agree upon the selection of such an appraiser, then 
     they shall each select an MAI appraiser and the two so designated shall 
     select a third. The Base Rent for the extension of the Term determined by 
     the selected MAI appraiser or any two of the three MAI appraisers so 
     chosen shall be binding on the parties and may not be appealed. If either 
     party fails to notify the other of its appraiser within thirty (30) days 
     after written request to do so, the MAI appraiser selected by the other 
     party shall make the determination of the Base Rent. Tenant's right to 
     exercise each option to extend the Term is contingent  upon Tenant's then 
     being current in its payment of Rent and all other amounts due under this 
     Lease, and otherwise being in compliance with all terms of the Lease 
     (subject to any permitted cure periods), at the time Tenant gives its 
     Notice of intent to exercise an option and on the first date of the newly 
     extended Term. At the time that Landlord notifies Tenant of the proposed 
     Base Rent for each extension of the Term, Landlord shall also notify 
     Tenant of the cost of the covered parking stalls during the extension of 
     the Term, and any dispute regarding the proposed parking fees shall be 
     resolved in the same manner used to resolve a dispute over Base Rent for 
     the extension 


                                       40
<PAGE>   43

     of the Term. The right to extend the Term shall not be affected by Tenant's
     sublease or assignment of any party of the Premises if (1) Landlord's so 
     agreed in writing when it consented to such sublease or assignment, or 
     (2) the assignment was permitted without Landlord's consent under 
     Paragraph 9(a), or (3) the sublease ends and Tenant retakes the Premises 
     prior to the end of the then current Term and Tenant is not in default at 
     the end of the then current Term. Notwithstanding the foregoing, if Tenant 
     has elected to extend the Term, all the terms of such extension have been 
     agreed by Landlord and Tenant and set forth in a fully executed written 
     extension of the Lease, then Tenant may enter a sublease under the terms 
     of Paragraph 9 that commences prior to the end of the then current term 
     and expires before the end of the newly extended Term without the loss of 
     its rights to renew the Term as provided herein and in the written 
     extension.

43.  USE OF ROOF AND BUILDING STORAGE.

     Tenant may not use the roof and building storage areas without prior 
     written permission of Landlord which Landlord may refuse or condition. 
     Tenant shall be allowed to install a satellite dish on the roof. If Tenant 
     receives permission to use the roof, roof use shall be restricted to 
     non-commercial telecommunications and other similar uses. Landlord will 
     not install or allow others to install commercial telecommunications 
     equipment on the roof. Any alterations of the roof or building storage 
     areas shall be in accordance with the provisions of this Lease and 
     requires Landlord's prior written approval. Tenant shall not enter onto 
     the roof unless accompanied by an employee or agent of Landlord.

44.  DEFINITION OF LANDLORD'S NEGLIGENCE.

     "Landlord's negligence and willful misconduct" refers to the negligence of 
     Pine Forest Co.'s officers. The other employees of Pine Forest Co. and its 
     agents are held to the standard of gross negligence. Nothing herein shall 
     be construed to make any individuals personally liable.

                             WORK LETTER AGREEMENT

     1.   TENANT IMPROVEMENTS. Landlord shall construct Tenant Improvements on
the Premises pursuant to Tenant Improvements Construction Documents and in
accordance with the Tenant Improvements Construction Contract. The Tenant
Improvements Construction Documents shall be prepared by or at the direction of
Landlord based on the Tenant Improvements Schematic Plans in a form that is
mutually acceptable to Tenant and Landlord, and shall be completed and approved
in writing by both Landlord and Tenant no later than May 31, 1998. The Tenant
Improvements Schematic Plans shall be prepared by or at the direction of Tenant
in a form that is mutually acceptable to Tenant and Landlord and shall be
completed and approved in writing by both Landlord and Tenant no later than
April 30, 1998. Landlord shall obtain all necessary permits for construction of
the Tenant Improvements.

     2.   BUILDING SHELL. Landlord shall construct the Building Shell on the
Premises pursuant to the Building Shell Construction Documents and in accordance
with the Building Shell Construction Contract.

     3.   COSTS OF TENANT IMPROVEMENTS. Landlord's Maximum Contribution shall be
sued only to pay Tenant Improvements Costs which include the cost of preparing
the Tenant Improvement Documents and other design fees and costs, all permitting
and inspection fees and costs related to the Tenant Improvements, all costs of
construction, labor and materials, contractor's profit and overhead for the
Tenant Improvements, taxes, bonds and all other fees and costs incurred in
constructing the Tenant Improvements.

     4.   DETERMINATION OF THE COST OF CONSTRUCTION. Within thirty (30) days
after approval of the Tenant Improvements Schematic Plans by Landlord and
Tenant, Landlord shall notify Tenant of the Projected Tenant Improvements Costs
pursuant to the Tenant Improvements Schematic Plans under the Tenant
Improvements Construction Contract. If the Projected Tenant Improvements Costs
exceed the Landlord's Maximum Contribution, of Seven Hundred Thousand Dollars
($700,000) then Tenant may (1) request changes to the Tenant Improvements
Schematic Plans to bring the Projected Tenant Improvements Costs below the
Landlord's Maximum Contribution, (2) tender the difference between the Projected
Tenant Improvements Costs and the Landlord's Maximum Contribution to the
Landlord, or (3) request that the Landlord advance up to the maximum amount of
Two Hundred Thousand Dollars ($200,000) ("Landlord Advance") to Tenant to
complete the Tenant Improvements, or any combination of the three, at Tenant's
election. Tenant shall be responsible to pay Landlord any Excess Tenant
Improvements Costs as described in Paragraph 13 below.

     5.   REPAYMENT OF THE LANDLORD ADVANCE. If Tenant requests a Landlord
Advance to pay a portion of the Tenant Improvements Costs, then the amount
advanced shall bear interest at the rate of twelve percent (12%) per annum. It
shall be amortized over the Initial Term of the Lease and shall be paid as
Additional Rent in monthly installments in advance, without notice, commencing
with the first month Rent is due under the Lease. Landlord shall



                                       45
<PAGE>   48
have the same rights to enforce the payment of the Landlord Advance as it does
to enforce payment of all Rent and Additional Rent due under the Lease. Tenant
shall sign such Notes, Guaranties, Amendment to the Lease, and other documents
Landlord deems reasonably necessary in connection with the Landlord Advance.
Landlord has no obligation to commence construction of the Tenant Improvements
until Landlord has received the difference between the Tenant Improvements Costs
and Landlord's Maximum Contribution or Tenant has executed those documents
Landlord required prior to making any Landlord Advance.

     6.   CONTRACTS. Landlord shall contract with the appropriate members of the
Project Team (other than Tenant's Representative) for services necessary to
construct the Building Shell and Tenant Improvements pursuant to the Tenant
Improvement Plans. The final Tenant Improvements Construction Contract (with
dollar amounts) shall be provided to Tenant and must be approved in writing by
Tenant within seven (7) days of receipt by Tenant and prior to commencement of
construction of the Tenant Improvements or effectiveness of such contract.
Landlord shall also provide Tenant with copies of Building Shell Construction
Documents with costs expunged so Tenant can review which items are allocated to
Tenant Improvement Costs and which items are allocated to the Building Shell.

     7.   DETERMINATION OF TENANT IMPROVEMENTS SUBCONTRACTORS. Landlord and
Tenant have agreed that General Contractor shall serve as contractor for the
Tenant Improvements pursuant to the Tenant Improvements Construction Contract
and have further agreed that the Mechanical Subcontractor and the Electrical
Subcontractor shall provide those services for the Tenant Improvements. For
every other subcontractor for the Tenant Improvements, General Contractor shall
obtain competitive bids which bids shall be available for Tenant's review and
comment if Tenant so requests. After receipt of such bids, Landlord and Tenant
shall each review and consult with each other regarding the bids whereupon the
subcontractors shall be selected by Landlord and General Contractor. Bids will
distinguish between Building Shell and Tenant Improvement Work. Approval of
Tenant's Improvement Construction Contract by Tenant shall be deemed approved of
the subcontractor competitive bids used in preparing the Tenant Improvements
Construction Contract.

     8.   RESPONSIBILITY FOR CONSTRUCTION. Landlord shall be responsible for
construction of the Building Shell and Tenant Improvements and shall employ the
Project Team as provided above. Landlord shall make all decisions regarding the
Building Shell. Landlord shall have control over the construction of the Tenant
Improvements in cooperation with the Tenant, and shall have the right to make
all final decisions regarding interpretation of the Tenant Improvements
Construction Documents, after making a good faith attempt to get Tenant's
approval of any element regarding the Tenant Improvement Construction Documents
which is subject to several interpretations, provided, if Tenant is not
available or does not provide an interpretation within twenty four (24) hours,
Landlord's decision is final. In the event Tenant or Landlord wishes to make a
material change in the Tenant Improvement Construction Documents, the party
needing or wishing to make the change shall notify the other in writing of the
change in the form a written change order. The change order shall describe the
change, the cost associated with making the change, and the delay associated
with making the



                                       46
<PAGE>   49
change, if any. General Contractor, Landlord and Tenant shall sign all said
change orders. Failure to sign or object in writing to a change order within two
(2) business days of the date the change order is submitted for approval shall
be deemed approval of the change order. If construction will be delayed until
approval of the change order is received, the General Contractor, Landlord,
Tenant or TI Architect may impose a shorter time limit on approval. If the cost
of the change will increase the projected Tenant Improvements Costs, the Tenant
shall pay the cost as a Tenant Improvement Cost pursuant to paragraph 10. 
Tenant's approval of the change order or failure to respond within two (2) 
business days shall be conclusive evidence that Tenant has approved the change 
and any delay or increased cost associated with the change as disclosed in the 
change order. If Landlord or its agents determine that changes or modifications 
should be made in the space plans, plans or specifications because of 
permitting requirements, requests of governmental authorities, design or 
construction efficiencies or other reasons, Landlord shall make such changes 
which Landlord deems necessary; provided, that if such changes would result in 
an increase in the Projected Tenant Improvements Costs, then Tenant or TI 
Architect must have approve such change before Tenant is liable to pay such 
increase.

      9.    CONSTRUCTION ADMINISTRATION. Landlord and Tenant shall each proceed 
with all necessary due diligence and in good faith to complete such matters as 
require their respective action or approval, and both parties agree to promptly 
and diligently respond to all questions and concerns raised by architects, 
engineers and other consultants. Landlord and Tenant shall each endeavor to 
respond to submissions from General Contractor and TI Architect promptly, on 
an on-going basis in order that revisions required by Landlord, Tenant or 
applicable governmental agencies, can be promptly completed. When Tenant 
approval or comment is requested, Tenant or TI Architect shall respond within 
two (2) business days of request unless a different response period is provided 
in this Agreement or unless both parties agree following a request by either. 
If the TI Architect believes that a response to a request of either Landlord or 
Tenant is required in less than two (2) business days, then the party requested 
shall respond within such shorter time period as prescribed by the TI 
Architect. During construction of the Building Shell and Tenant Improvements, 
Landlord, Tenant, General Contractor and TI Architect together with other 
applicable consultants shall meet every week (unless meeting is cancelled) in 
order to review status and scheduling of Tenant Improvements construction and 
determine possible changes required, delays anticipated, costs being incurred 
and all related matters. At these meetings, change orders will be presented, 
discussed and executed (subject to the two-day deadline).

      10.   TENANT IMPROVEMENT COSTS. Landlord's Maximum Contribution, 
together with any Landlord Advance, shall be used only to pay Tenant 
Improvements Costs. Landlord agrees that the Landlord's Maximum Contribution 
and Landlord Advance, if any, shall not be applied against, nor shall Tenant be 
liable for, costs associated wit the construction of the Building Shell, 
landscaping, public area restrooms, electrical rooms, phone closets or other 
public areas of the Premises except for modifications requested by Tenant such 
as installation of cabinets, reception desk and other fixtures located in the 
reception area. Tenant shall be responsible for paying any Excess Tenant 
Improvements Costs if applicable and shall tender said amounts to



                                       47

<PAGE>   50
Landlord within five (5) days of written demand as a condition to Landlord
commencing or continuing with construction of the Tenant Improvements.

     11.  EARLY ACCESS. Tenant shall be given access to the Premises prior to 
installation of the ceiling grid in order to allow Tenant to install telephone 
and other communications and media lines and systems, computer cabling, and 
related similar matters. The date of Early Access to the Premises and the time 
by which installation of Tenant's Work must be completed will be coordinated 
with the General Contractor. Tenant and General Contractor shall work together 
to ensure that Tenant's Work is completed in an efficient and timely manner and 
will not unreasonably impede, interfere with or delay the progress of 
construction of the Tenant Improvements. Tenant shall perform such installation 
in accordance with all guidelines promulgated by General Contractor and shall 
execute and require its contractors and subcontractors to execute such 
releases, indemnifications and other documents that General Contractor requires 
of its own subcontractors. Any and all costs of installation of such items 
shall be at Tenant's sole cost and expense.

     Tenant shall also be given Early Access to the Premises for purposes of 
storing its furniture and personal property in portions of the Premises in 
which Tenant Improvements are substantially complete. General Contractor shall 
designate the areas in which such storage can occur to ensure that such storage 
will not interfere with the construction of the Tenant Improvements. Tenant 
hereby releases Landlord, General Contractor and all of their agents, 
employees, licensees, invitees and subcontractors from all liability for loss 
or damage to Tenant's personal property stored on the Premises prior to the 
Commencement Date. Tenant agrees to maintain insurance on all said property and 
hereby assumes full risk of loss or damage to said personal property and hereby 
agrees to defend, indemnify and hold Landlord, General Contractor, their 
agents, employees, licensees, invitees and subcontractors harmless from any 
claims, loss or liability related to said stored personal property.

     12.  INSPECTION AND PUNCHLIST. During the construction of the Building 
Shell and the Tenant Improvements, Tenant, Landlord and General Contractor 
shall meet weekly and shall inspect the Premises regularly. In the event Tenant 
notices any defects in construction or variations from the Building Shell 
Construction Documents or Tenant Improvement Construction Documents, Tenant 
shall bring such variations to General Contractor's and Landlord's attention, 
and any such discrepancies or defects shall be remedied as soon as practicable. 
Upon Substantial Completion of the Tenant Improvements, General Contractor 
and/or Landlord shall notify Tenant. Tenant shall, within forty eight (48) 
hours of such notification, conduct an inspection of the Premises and prepare 
and submit to Landlord an itemized list ("Punchlist") of all matters which must 
be installed, completed or corrected so as to bring the Tenant Improvements 
into compliance with the Tenant Improvement Construction Documents; provided, 
however, that no matter on the Punchlist shall exceed the scope, quality or 
quantity of the Tenant Improvements as set forth in the Tenant Improvement 
Construction Documents.

     Once Tenant has taken occupancy of the Premises, Tenant shall notify 
Landlord in writing within sixty (60) days of taking possession of the Premises 
of any defects in construction or variations from the Tenant

                                       48
 
 

 
<PAGE>   51
Improvement Construction Documents. Landlord shall undertake to repair said
deviations within sixty (60) days of receiving written notice of the need to
correct or repair said item. On the sixty first (61st) day after the Tenant has
taken possession of the Premises, Tenant shall be deemed to have accepted the
Premises "as is," in their then current condition subject only to corrections of
items already noted in writing to Landlord and not yet corrected or items
covered by warranty by third parties.

     13.  TENANT ADVANCES OF EXCESS TENANT IMPROVEMENTS COSTS. Landlord shall
advance all Tenant Improvements Costs up to the Landlord's Maximum Contribution
(and full Landlord's Advance, if applicable). Thereafter, Landlord's obligation
to continue with the construction is contingent upon Tenant paying 100% of all
Excess Tenant Improvements Costs upon five (5) business days of demand in
advance of construction. Unless Landlord agrees otherwise in writing, Tenant
shall be solely responsible for providing all Tenant's Personal Property for its
business at the Premises and Tenant shall not use any amounts provided by
Landlord for said property.

     14.  DELAYS. Landlord will use its best reasonable efforts to complete 
construction of the Tenant Improvements by November 1, 1998. Landlord and 
Tenant agree that the Commencement Date of the Lease, and the time periods for 
Substantial Completion may be extended in accordance with change orders as 
provided in paragraph 8 or by other causes not ascertainable at this time. If a 
delay is caused by Tenant's failure to make required payments for Change 
Orders, Excess Tenant Improvement Costs or failure to complete Tenant's Work on 
time or other reasons attributable to Tenant and such delays cause an extension 
of the Commencement Date beyond November 1, 1998 under this Agreement which has 
not been agreed to in a change order, Landlord shall give Tenant written notice 
of the expected delay and Commencement Date of the Lease shall be November 1, 
1998. The Notice shall set forth the reasons for Landlord's conclusion that the
delay is caused by Tenant. In the event Tenant believes that it is not 
responsible for the delay, it shall so notify Landlord of the reason for its 
conclusion. If Landlord and Tenant cannot agree, then the matter shall be 
submitted to binding arbitration. The Tenant may request arbitration only if 
Tenant commences tendering the Rent to Landlord on November 1, 1998 and 
continues to tender Rent each month until the dispute is resolved. If the 
arbitrator concludes that the delay was not attributable to Tenant, the Tenant 
shall be credited for Rent paid until the Premises are Substantially Complete.

Arbitration shall be conducted by an arbitrator mutually agreeable to the 
parties. If the parties cannot agree upon an arbitrator, each shall submit the 
name of an acceptable arbitrator and those two arbitrators shall select a third 
arbitrator who shall conduct the arbitration. The prevailing party shall bear 
the cost of the arbitration. The parties must designate an arbitrator who is 
familiar and experienced with construction issues. The arbitration shall be 
conducted in accordance with the rules and procedures set forth by the American 
Arbitration Association for the Construction Industry and shall be 
non-appealable and binding on the parties.

     14.1. Delays From Force Majeure. In the event Substantial Completion is 
delayed beyond November 1, 1998 by Force Majeure (as defined in paragraph 36 of 
the Lease), then the Scheduled Substantial Completion Date shall be

                                       49

    

 
<PAGE>   52
extended by the period of such delay, and the scheduled Commencement Date
of the Lease shall be likewise extended. The inability to obtain all required
permits and approvals for the construction of the Premises shall not be included
in Force Majeure, except to the extent such inability is caused by Tenant Delay.
Landlord nevertheless acknowledges that Substantial Completion prior to 
November 1, 1998, is critical to Tenant's business and that Landlord shall, upon
consultation with Tenant, attempt to determine measures which could be taken to
minimize any delay which may occur in the event of delay occurring due to Force
Majeure; provided, however, that neither Landlord nor Tenant shall be obligated
to incur additional costs other than those anticipated hereunder in the event of
delay occurring due to Force Majeure. In the event of Force Majeure occurring,
Landlord shall give Tenant written notice of the same, together with the
estimated period of such Force Majeure. Either Tenant or Landlord may elect, by
written notice to the other, to augment the construction schedule, at such
party's sole cost and expense, in order to avoid the effects of any Force
Majeure. Estimates of such costs of augmentation of the Construction Schedule
shall be provided by General Contractor.

     15.  TENANT'S DEFAULT. If Tenant fails to make any payments required to be
made hereunder, or otherwise fails to meet its obligations hereunder or under
the Lease, Landlord may (1) discontinue construction of the Tenant Improvements,
(2) terminate the Lease on ten (10) days written notice and/or (3) pursue all
other remedies available in the Lease and in law and equity including recovering
damages for lost profit, lost rent, attorney fees and costs incurred in
enforcing the terms of this Agreement and any and all other remedies available.

     16.  COOPERATION. Tenant and Landlord shall cooperate in good faith with
each other at all times while Landlord is obtaining the necessary approvals,
permits, plans and specifications and throughout construction. Both parties
shall provide prompt response to any questions or concerns that may arise
relating to the Tenant Improvements and shall respond in a timely and
professional manner to all questions and requests from the other.

     17.  INCORPORATION. This Work Letter Agreement is a part of and is
incorporated into the Office Lease by and between the parties and is in addition
to those provisions provided in paragraph 2 of said Office Lease relating to
Tenant Improvements.

mortgagee in possession or successor in title to the property, for 
accountability for any security deposit required by Landlord under said Lease 
unless such sums have actually been received by           ("Lender") as cash 
security for Tenant's performance of this Lease.

Tenant understands that its Lease may be assigned as collateral security for a 
mortgage loan to be granted to Landlord by (Lender) under a Collateral 
Assignments of Lease form containing (among others) agreements by and 
restrictions on Landlord. Tenant further understands that, without (Lender's) 
prior written authorization as Assignee, Landlord will not thereafter modify,

accept pre-payment of any Rent (except as the Lease may otherwise specify). By 
accepting this Estoppel Certificate, Lender agrees

Tenant's quiet enjoyment of the Premises and will respect Tenant's rights under
the Lease after a foreclosure, trustee's sale or deed in lieu thereof. Tenant

rights under said assignment and hereby agrees to be bound by said agreements 
and restrictions, to the extent such agreements do not reduce Tenant's rights 
or enlarge Tenant's obligations under the Lease or otherwise.

Tenant will not assign its leasehold without (Lender's) written consent, which 
shall not be unreasonably withheld, conditioned or delayed.
