        1.  MASTER LEASE.  Sublessor is the lessee under a written lease
dated September 14, 1984, as amended (the "Master Lease"), wherein The

property located in the City of Bellevue, County of King, State of Washington,
described as the entire 20th floor of the Skyline Tower consisting of a
Rentable Area of 16,989 square feet of space ("Master Premises").  The Trustees
under the Will and of the Estate of James Campbell, Deceased ("Landlord"), are
the successor-in-interest to The Prudential Insurance Company of America, a New
Jersey corporation, and Sublessor is the successor-in-interest to Williams,
Lanza, Kastner & Gibbs, a Washington general partnership.  The Master Lease is
attached hereto as Exhibit "A".

        2.  PREMISES.  Sublessor hereby subleases to Sublessee on the terms and
conditions set forth in this Sublease the following portion of the Master
Premises ("Premises"):

        The portion of the Master Premises outlined in black on the attached
        Exhibit "B" consisting of a Rentable Area of 13,589 square feet of
        space.

        3.  WARRANTY BY SUBLESSOR.  Sublessor warrants and represents to
Sublessee that the Master Lease has not been amended or modified except as
expressly set forth herein, that Sublessor is not now, and as of the
commencement of the Term hereof will not be, in default or breach of any of the
provisions of the Master Lease, and that Sublessor has no knowledge of any
claim by Landlord that Sublessor is in default or breach of any of the
provisions of the Master Lease.

        4.  TERM.  The Term of this Sublease shall commence on January 1,
1997 (the "Commencement Date") and end on November 30, 1999 (the "Termination
Date"), unless otherwise sooner terminated in accordance with the provisions of
this Sublease.  Possession of the Premises ("Possession") shall be delivered to
Sublessee on the Commencement Date.  If for any reason Sublessor does not
deliver Possession to Sublessee on the Commencement Date, Sublessor shall not
be subject to any liability for such failure, the Termination Date shall not be
extended by the delay, and the validity of this Sublease shall not be impaired,
but rent shall abate until delivery of Possession.  Notwithstanding the
foregoing, if Sublessor has not delivered Possession to Sublessee within thirty
(30) days after the Commencement Date, then at any time thereafter and before
delivery of Possession, Sublessee may give written notice to Sublessor of
Sublessee's intention to cancel this Sublease.  Said notices shall set forth
an effective date for such cancellation which shall be at least ten (10) days
after delivery of said notice to Sublessor.  If

<PAGE>   3
Sublessor delivers Possession to Sublessee on or before such effective date,
this Sublease shall remain in full force and effect.  If Sublessor fails to
deliver Possession to Sublessee on or before such effective date, this Sublease
shall be cancelled, in which case all consideration previously paid by
Sublessee to Sublessor on account of this Sublease shall be returned to
Sublessee, this Sublease shall thereafter be of no further force or effect, and
Sublessor shall have no further liability to Sublessee on account of such delay
or cancellation.  If Sublessor permits Sublessee to take Possession prior to
the commencement of the Term for the purpose of occupying the Premises and if
Sublessee elects to take Possession prior to the commencement of the Term for
such purpose, such early Possession shall not advance the Commencement Date or
the Termination Date and shall be subject to the provisions of this Sublease,
including without limitation, the payment of rent, provided, however, that
Sublessee may have access to the Premises no later than December 1, 1996 for
the limited purposes of utilization of up to ten perimeter offices, space
planning, planning of Sublessee's move to the Premises, and installation of
Sublessee's fixtures, furnishings and equipment without payment of rent.  The

Property Taxes (as defined in the Master


                                       2
<PAGE>   4

Lease) and Operating Expenses (as defined in the Master Lease) incurred by
Landlord in the operation of the Building during the term of the Lease. This
Sublease is a "gross lease" which requires Sublessee to pay to Sublessor
Sublessee's proportionate share of increases in Property Taxes (as defined in
the Master Lease) and Operating Expenses (as defined in the Master Lease)
during the Term. The Building Area is 390,160 square feet, the Premises Area is
13,589 square feet and Sublessee's proportionate share is, accordingly, three
and 38/100 percent (3.48%). Sublessee shall pay to Sublessor as additional rent
in equal monthly installments, in advance, three and 38/100 percent (3.48%) of
the increase, if any, in Property Taxes (as defined in the Master Lease) and
Operating Expenses (as defined in the Master Lease) incurred by Landlord in the
operation of the Building during each year of the Term over the Property Taxes
(as defined in the Master Lease) and Operating Expenses (as defined in the
Master Lease) incurred by Landlord in the operation of the Building during the
calendar year 1997 (the "Base Year"), as reasonably estimated by Sublessor. The
Master Lease provides for the payment by Sublessor or Property Taxes (as
defined in the Master Lease) and Operating Expenses (as defined in the Master
Lease) in equal monthly installments, in advance, on the basis of an estimate
thereof by Landlord and adjustments to such estimates within ninety (90) days
after the end of each calendar year. Sublessor's estimate shall be based on
Landlord's estimate. Sublessee shall have the same right to dispute Sublessor's
estimate and Sublessor's statement as Sublessor has to dispute Landlord's
estimate and Landlord's statement pursuant to Section 3.b. of the Master Lease.
Sublessor's estimate shall be adjusted as and when adjustments between
estimated and actual Property Taxes (as defined in the Master Lease) and
Operating Expenses (as defined in the Master Lease) incurred by Landlord in the
operation of the Building are made under the Master Lease. If any such
adjustment shall occur after the expiration or earlier termination of the Term,
then the obligations of Sublessor and Sublessee under this Section 5(b) shall
survive such expiration or termination. Sublessor shall furnish to Sublessee
copies of all statements submitted by Landlord to Sublessor of actual or
estimated Property Taxes (as defined in the Master Lease) and Operating
Expenses (as defined in the Master Lease) during the Term.

        6.  SECURITY DEPOSIT.  Sublessee shall not be required to pay a
Security Deposit.

        7.  USE OF PREMISES.  The Premises shall be used and occupied only for
general office purposes in accordance with the Master Lease, and for no other
use or purpose without the prior written consent of Landlord in accordance with
the Master Lease and the prior written consent of Sublessor, which consent
shall not be unreasonably withheld.

        8.  ASSIGNMENT AND SUBLETTING.  Sublessee shall not assign this
Sublease or further sublet all or any part of the Premises without the prior
written consent of Landlord in accordance with the Master Lease and the prior
written consent of Sublessor, which consent shall not be unreasonably withheld.

        9.  OTHER PROVISIONS OF SUBLEASE.  All applicable terms and conditions
of the Master Lease are incorporated into and made a part of this Sublease as
if Sublessor were the lessor thereunder, Sublessee the lessee thereunder, and
the Premises the Master Premises, except for the 

                                       3
<PAGE>   5

following: Paragraph 43-3 captioned "Right of First Refusal/Option on
Additional Space", Paragraph 43-4 captioned "Option to Extend the Lease Term",
Paragraph 43-6 captioned "Death or Retirement of Tenant's Partners", and
Exhibit C Tenant Workletter, all as set forth in the Skyline Tower Lease
Agreement dated September 14, 1984 and the addendums and exhibits thereto, and
Paragraph 3 captioned "Space Pocket", Paragraph 6 captioned "Rental Abatement",
Paragraph 7 captioned "Tenant Improvements", Paragraph 8 captioned "Right of
First Refusal; Expansion Options", Paragraph 11 captioned "Rental Adjustment
for Weatherly Space" and Paragraph 12 captioned "No Further Renewal Rights",
all as set forth in the Lease Extension and Modification Agreement dated
October 2, 1989. Notwithstanding anything to the contrary in the Master Lease,
Sublessor shall not have any obligation to make tenant improvements to the
Premises, except as expressly set forth in this Sublease, and Sublessee shall
not have any right to expand the Premises or extend the Term. Sublessee assumes
and agrees to perform the lessee's obligations under the Master Lease during
the Term to the extent that such obligations are applicable to the Premises,
except that the obligation to pay rent to Landlord under the Master Lease shall
be considered performed by Sublessee to the extent and in the amount rent is
paid to Sublessor in accordance with Section 5 of this Sublease. Sublessee
shall not commit or suffer any act or omission that will violate any of the
provisions of the Master Lease. Sublessor shall exercise due diligence in
attempting to cause Landlord to perform its obligations under the Master Lease
for the benefit of Sublessee. If the Master Lease terminates, this Sublease
shall terminate and the parties shall be relieved of any further liability or
obligation under this Sublease, provided however, that if the Master Lease
terminates as a result of a default or breach by Sublessor or Sublessee under
this Sublease and/or the Master Lease, then the defaulting party shall be
liable to the nondefaulting party for the damage suffered as a result of such
termination. Notwithstanding the foregoing, if the Master Lease gives Sublessor
any right to terminate the Master Lease in the event of the partial or total
damage, destruction, or condemnation of the Master Premises or the building or
project of which the Master Premises are a part, the exercise of such right by
Sublessor shall not constitute a default or breach hereunder.

        10.  TENANT IMPROVEMENTS.  The Premises shall be subleased in "AS IS"
condition except for the following work (the "Tenant Improvements") which is
described with reference to Exhibit "C" attached hereto:

Sublessee agree to all of the terms and conditions set forth in this Consent
and Agreement (execution of this Consent and Agreement by the Sublessor and
Sublessee will constitute such agreement by the respective entities). Landlord
also hereby consents to the installation of the Tenant Improvements set forth
in the Sublease. The capitalized terms used in this Consent and Agreement and
not defined herein shall have the meaning given to such terms in the Sublease.

        2.  Neither the Sublease nor this Consent and Agreement shall be
construed to relieve Sublessor of any liabilities or obligations whatsoever
under the Master Lease. Sublessor shall continue to be fully and primarily
liable for the full performance of all obligations of the tenant under the
Master Lease.

        3.  If Sublessor is in default under the terms of the Master Lease,
Landlord shall have the right to take all actions available to Landlord under
the Master Lease by law, including without limitation, the right to commence an
unlawful detainer action against Sublessor and Sublessee.

        4.  All improvements to be made to the subleased premises ("Subleased
Premises") pursuant to the Sublease are subject to Landlord's consent and
approval as provided in the Master Lease.

        5.  Whenever the Master Lease gives Landlord a right of involvement,
such as a right to approve, consent, cooperate or decide, Landlord shall have
and keep that right with respect to

                                       1
<PAGE>   11

both Sublessor under the Master Lease and Sublessee under the Sublease. If
Landlord and Sublessor disagree over any decision, Landlord's decision shall
control. If, for example, the Master Lease requires Landlord's prior consent to
any alterations or additions to the Sublease Premises and if Sublessee desires
to make alterations or additions to the Sublease Premises, it must obtain the
prior consent of both Landlord and Sublessor.

        6.  If the Master Lease terminates or is terminated prior to the
expiration of the term of the Sublease, the Sublease also shall terminate,
except as otherwise provided below. Neither Sublessor nor Sublessee shall have
any claim or cause of action against Landlord as a result of such termination
of the Sublease. Landlord, at its sole option, to be exercised by written
notice to Sublessee, may elect to keep the Sublease in effect even though the
Master Lease is terminated. If Landlord so elects to keep the Sublease in
effect, the Sublease shall continue in full force and effect as a direct lease
between Landlord and Sublessee on the terms and conditions contained therein.
In such event, Sublessee agrees to recognize Landlord as the sublessor under
the Sublease.

        7.  Sublessor will pay Landlord's reasonable attorneys' fees in
reviewing the Sublease and preparing this Consent and Agreement. Landlord also
shall be reimbursed by either Sublessor or Sublessee (as they shall agree
between them) for the cost of a new suite plaque for the Subleased Premises,
new signage in the Building directory and rekeying the Subleased Premises;
provided Sublessor and Sublessee shall be jointly and severally obligated to
Landlord for such costs until they are paid.

        8.  The indemnity and other agreements contained in the Sublease and in
the Master Lease shall apply with equal force and effect between Sublessee and
Landlord (with Sublessee indemnifying Landlord in accordance with the terms of
the Sublease and the Master Lease) and Landlord shall be named as an additional
insured on any insurance required to be maintained by Sublessee under the
Sublease.

        9.  This Consent and Agreement shall not relieve Sublessor of its
obligation to obtain Landlord's consent to (a) any further sublease of all or
part of the Subleased Premises (or any additional premises leased to Sublessor
pursuant to the Master Lease and not covered by the Sublease), or (b) any
assignment of the Master Lease. Neither the Sublease nor this Consent and
Agreement shall confer upon the Sublessee any right to further sublease the
Subleased Premises or assign its rights under the Sublease in either case
without Landlord's consent.

        10.  A failure by Sublessor or Sublessee to comply with any of the
terms or conditions of this Consent and Agreement shall constitute a default
under the Master Lease. If any party to this Consent and Agreement commences an
action or other legal proceeding to enforce performance of any of the terms or
provisions hereof or of the Master Lease or to secure damages for or an
injunction against the breach thereof (including assertion of any counterclaim,
cross-

claim or cross-complaint or claim in a proceeding in bankruptcy, receivership
or other proceeding instituted  by a party hereto or by others), the prevailing
party in such action or proceeding shall, in addition to such other relief as
it may obtain, be entitled to recover from the other party all of its costs
incurred, including reasonable attorneys' fees, in any such action or
proceeding or any appeal from any order, award or judgment therein.

        11.  Any options to extend the Master Lease, rights of first offer,
rights of first refusal or other rights to lease additional space or rights to
expand the premises may not be exercised by or for the benefit of Sublessee. *

        12.  Sublessor and Sublessee shall not amend or modify the Sublease
without Landlord's prior written consent.

        13.  This Consent and Agreement shall not be effective until and unless
an original executed by Sublessor and Sublessee has been delivered to Landlord.

        Dated as of the day and year first above written.

                                        LANDLORD:
