2.   Premises.

     (a) Tenant hereby acknowledges that the premises shall be delivered in an
"as

                                                          3





is" condition and that Landlord, except as may be expressly agreed by Landlord
in writing, has no obligation to alter, repair, renovate, or render fit for
tenant's occupancy, any part of the premises. Landlord reserves to itself the
use of the roof, exterior walls and the area beneath the premises, together with
the right to install, maintain, use, repair and replace plumbing, telephone
facilities, equipment, machinery, connections, pipes, ducts, conduits, and wires
leading through the premises and serving other parts of the Building in a manner
and in locations which will not unreasonably interfere with Tenant's use.

     (b) In the event Landlord determines to permit early occupancy of the
premises and, therefore, informs Tenant in writing that the premises are ready
for occupancy prior to the date set forth in the Basic Lease Information for the
commencement of the term of the Lease, Tenant shall have the right to take early
occupancy of the premises on such date as Landlord and Tenant shall agree, and
notwithstanding the provisions of paragraph 3 below, the term of the Lease shall
commence upon such occupancy.

     (c) The occupancy by Tenant of the premises shall constitute an
acknowledgment by Tenant that the premises are then in good, sanitary and
tenantable condition and repair. Notwithstanding the foregoing, Iandlord
represents and warrants, to (he best of its knowledge without inquiry, to Tenant
that, as of the Commencement Date, tile Premises, including any improvements
made by Landlord, shall be in compliance with all laws and regulations, and
built in a good and workmanlike manner with good materials and the equipment and
Building services serving the Premises shall be in good working order.

3.   Term. The term of this Lease shall commence and, unless sooner terminated,
shall end on the date respectively specified in the Basic Lease Information. If
Landlord for any reason cannot deliver possession of the premises to Tenant by
the date specified for term commencement, this Lease shall not be void or
voidable nor shall Landlord be liable to Tenant for any damage resulting
therefrom, but in that event, provided that the delay is not occasioned by the
act or omission of tenant, rental shall be waived for the period between the
commencement of such term and the date when possession is delivered. Provided,
however, if Landlord has not delivered the premises to Tenant within sixty (60)
days of the Term Commencement, this Lease shall be deemed null and void without
liability to either party, so long as such failure is not due to a delay caused
by the act of omission of Tenant.

4.   Rent. Tenant shall pay to Landlord as rental for the use and occupancy of
the premises, at the times and in the manner hereinafter provided, the following
sums of money:

     (a) Tenant shall pay to Landlord minimum rent in the amount specified in
the Basic Lease Information per year, payable in equal monthly installments in
advance on the commencement of the term hereof and on or before the first day of
each and every successive calendar month during the term hereof. If the term
commences on other than

                                        4





the first day of a calendar month, the first payment of rent shall be
appropriately prorated on the basis of a 30-day month.

     (b) Tenant shall pay, as additional rent, all sums of money required to be
paid to Landlord pursuant to paragraphs 5, 6, 7, 10, 13 and 16 below, and all
other sums of money or charges required to be paid by Tenant hereunder in
addition to minimum rental, whether or not the some are designated "additional
rent". If such amounts or charges are not paid at the time provided in this
Lease, they shall nevertheless be collectible as additional rent with the next
installment of minimum rental thereafter falling due, but nothing herein
contained shall be deemed to suspend or delay the payment of any amount of money
or charge at the time the same becomes due and payable hereunder, or limit any
other remedy of Landlord. All amounts of money payable by Tenant to Landlord
under this Lease, if not paid when due, shall bear interest from the due date
until paid at the rate of the greater of 15% per annum or the prime rate
publicly announced by the Seafirst Bank at its main office in Seattle Washington
or its successor or its equivalent size competitor in the Seattle market place
should Seafirst Bank cease to exist, but not to exceed the maximum rate of
interest permitted by law ("Default Interest"). All payments due from Tenant to
Landlord hereunder shall be made to Landlord without deduction or offset in
lawful money of the United States of America at Landlord's address for notices
hereunder, or to such other person at such other place as Landlord may from time
to time designate in writing to Tenant.

     (c)Tenant hereby acknowledges that late payment by Tenant to Landlord of
rent and other sums due hereunder after the expiration of any applicable grace
period will cause Landlord to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain. Such costs
include, but are not limited to, processing and accounting charges, and late
charges which may be imposed on Landlord by the terms of any mortgage or trust
deed covering the premises. Accordingly, if any installment of rent or any other
sums due from Tenant shall not be received by Landlord when due Tenant shall pay
to Landlord a late charge equal to 6% of such overdue amount. The parties hereby
agree that such late charge represents a fair and reasonable estimate of the
costs Landlord will incur by reason of late payment by Tenant, Acceptance of
such late charge by Landlord shall in no event constitute a waiver of Tenant's
default as provided above, or prevent Landlord from exercising any of the other
rights and remedies available to Landlord hereunder or at law.

5.   Taxes and Assessments. In addition to the monthly rental and other charges
to be paid by Tenant hereunder, Tenant shall reimburse Landlord upon demand for
any and all taxes, assessments, levies, fees, charges and impositions whatsoever
levied or imposed or assessed by any authority having the direct or indirect
power to tax, including, without limitation, any city, county, state or federal
government or any improvement or other assessment district, whether or not
consented to or joined in by Landlord, payable by Landlord (other than income
taxes, measured by the net income of Landlord from all

                                        5





sources), whether or not now customary or within the contemplation of the
parties hereto on the date of this Lease: (a) upon, measured by or reasonably
attributable to the cost or value of tenant's equipment, furniture, fixtures and
other personal property located in the premises or by the cost or value of any
leasehold improvements made in or to the premises by or for Tenant, other then
building standard tenant improvements made by Landlord, regardless of whether
title to such improvements shall be in Tenant or Landlord; (b) upon or measured
by the rental payable hereunder, including without limitation any gross income
tax or excise tax levied by any city, county, state, federal or other
governmental body with respect to the receipt of such rental; (c) upon or with
respect to the possession, leasing, operation, management, maintenance,
improvement, alteration, repair, use or occupancy by Tenant of the premises or
any portion thereof; (d) upon (his transaction or any document to which Tenant
is a party creating or transferring an interest or an estate in the premises. In
the event that it shall not be lawful for Tenant so to reimburse Landlord, the
monthly rental payable to Landlord under this Lease shall be revised to net

$2,000,000. This insurance shall carry a contractual coverage endorsement
specifically insuring the performance by Tenant of its indemnity agreement
contained in paragraph 15 above. If in the opinion of Landlord's insurance
advisor, based on a substantial increase in recovered liability claims, the
aforesaid amounts of coverage are no longer adequate, then such coverage shall
be proportionately increased.


                                       14





          (2) Worker's Compensation Insurance and Employer's Liability Insurance

Employer's Liability Insurance shall have a minimum coverage of $1,000,000 per
person and per occurrence.

          (3) Fire insurance with standard extended coverage of "all risk"
endorsement, including, without limitation, vandalism and malicious mischief, to
extent of 90% of the replacement value of all furnishings, trade fixtures,
leasehold improvements, equipment, merchandise and other personal property and

from any such insurance shall be held in trust to be used only for the repair or
replacement of the improvements, fixtures and other property so insured.

     (b) Landlord may elect to procure and maintain liability insurance and
insurance covering fire and such other risks of direct indirect loss or damage
as it reasonably deems appropriate, including extended and broad form coverage
risks, mudslide, land subsidence, volcanic eruption, flood and earthquake, on
leasehold as improvements in the Building. Tenant shall reimburse Landlord for
the costs of all such insurance as part of Operating Expenses reimbursable
pursuant to paragraph (6). Any insurance coverage herein provided shall be for
the benefit of Landlord, Tenant and any additional designated insured, as their
interests may appear, Tenant shall not adjust losses or execute proofs of loss
under such policies without Landlords prior written approval.

     (c) Should this Lease be canceled pursuant to the provisions of paragraph
14 above by reason of damage or destruction and Tenant is thus relieved of its
obligation to restore or rebuild the improvements on the premises, any insurance
proceeds for damage to the premises, including all fixtures and leasehold
improvements thereon, shall belong to Landlord, free and clear of any claims by
Tenant.

     (d) All policies of insurance described in this paragraph 16 of which
Tenant is to procure and maintain, shall be issued by good, responsible
companies, reasonably acceptable to Landlord and qualified to do business in the
state in which the Building is situated. Executed copies of such policies of
insurance or, at Landlord's election, certificates thereof, shall be delivered
to Landlord and any additional designated insureds within 10 days after delivery
of possession of the premises to Tenant and thereafter within 30 days prior to
the termination or expiration of the term of each existing policy. All public
liability and property damage policies shall contain the following provisions:
(1) Landlord, and any additional designated insureds although named as insured,
shall nevertheless be entitled to recovery under said policies for any loss
occasioned to them, their servant , agents and employees by reason of the
negligence of Tenant, its officers, agents or employees; (2) the company writing
such policy shall agree to give Landlord and any additional designated insured
not less than 30 days' notice in writing prior to any cancellation, reduction or
modification of such insurance; and (3) at the election of

                                       15





Landlord's mortgagee, the proceeds of any insurance shall be paid to a trustee
or depository designated by Landlord's mortgagee. All public liability, property
damage and other casualty policies shall be written as primary policies, not
entitled to contribution from, nor contributing with, any coverage which
Landlord may carry.

     Tenant hereby acknowledges that the late delivery by Tenant to Landlord of
the insurance certificates or policies referred to above will cause Landlord to
incur costs nol contemplated by this lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges and penalties which may be imposed on Landlord
by the terms of any mortgage or trust deed covering the premises. Accordingly,
if any insurance certificate or policy required to be delivered by Tenant above
shall not be received by Landlord at the time prescribed above, Tenant shall pay
to Landlord a charge in the sum of $300. The parties hereby agree that such
charge represents a fair and reasonable estimate of the costs Landlord will
incur by reason of late delivery by Tenant, and acceptance of such charge by
Landlord shall in no event constitute a waiver of Tenant's default with respect
to such late delivery, nor prevent Landlord from exercising any of the other
rights and remedies available to Landlord hereunder or at law.

     (e) Notwithstanding anything to the contrary contained within this
paragraph, Tenant's obligations to carry the insurance provided for herein may
be brought within the coverage of the so-called blanket policy or policies of
insurance carried and maintained by Tenant; provided, however, that (1) Landlord
and such other persons shall be named as additional insureds thereunder as their
interests may appear; (2) the coverage afforded to Landlord and such other
persons will not be reduced of diminished by reason of the use of such blanket
policy of insurance; and (3) all other requirements set forth herein are
otherwise satisfied.

     If Tenant should fail either to acquire the insurance required pursuant to
this paragraph 16 and to pay the premiums therefor or to deliver required
certificates or policies, Landlord may in addition to any other rights and
remedies available to Landlord, acquire such insurance and pay the requisite
premiums therefor, which premiums shall be payable by Tenant to Landlord
immediately upon demand.

     (g) Landlord and Tenant hereby waive any rights each may have against the
other for loss or damage to its property or property in which it may have an
interest where such loss is caused by a peril of the type generally covered by
fire insurance with extended coverage or arising from any cause which the
claiming party was obligated to insure against under this Lease, and each party
on behalf of its insurer waives any right of subrogation that the insurer might
otherwise have against the other party. The parties agree to cause their
respective insurance companies insuring the premises or insuring their property
on or in the premises to execute a waiver of any such rights of subrogation.


                                       16

master leasehold estate to so much of the premises or a portion of the Building
necessary for Tenant's occupancy by right of eminent domain or other authority
of law, or a voluntary transfer tinder the threat of the exercise thereof, that
the premises are not suitable for Tenant's intended use. The term "partial
taking" means the taking of only a portion of the premises or the Building which
does not constitute a total taking as above defined.

     (b) If during the term hereof there shall be a total taking then this
Lease, and the leaschold estate of Tenant in and to the premises, shall cease
and terminate as of the date possession is taken. As used in this paragraph, the
phrase "date possession is taken" means the date of taking actual physical
possession thereof by the condemning authority or such earlier date as the

such event, Tenant shall not be entitled to any portion of the profit, if any,
which Landlord may realize on account of such termination and reletting.
