Rent set forth in Section 1(f) of the Lease shall be revised as follows:

                                                              AMEND TO LEASE 3.2

</TABLE>

      3. Rent Adjustment. So long as Tenant is not in default beyond the
expiration of any applicable notice and cure period, (a) Monthly Base Rent for
December 2004 through August 2005 shall be waived, and (b) Tenant shall be
entitled to a credit against Monthly Base Rent for the month of September 2005
in the amount of $3,244.08 (collectively, the "RENT ADJUSTMENT").
Notwithstanding the Rent Adjustment, Tenant shall remain liable for Tenant's
share of Operating Costs and Real Property Taxes in accordance with Section 5 of
the Lease.

      4. Termination of Additional Allowance Reimbursement. So long as Tenant is
not in default beyond the expiration of any applicable notice and cure period,

(additional Tenant Improvement costs) advanced by Landlord under Exhibit D to
the Lease and confirmed in the Confirmation of Lease Terms dated August 28,
2000.

      5. Tenant's Share of Operating Costs and Real Property Taxes. Effective
December 1, 2004, Section 5(b)(i) of the Lease is hereby amended as follows:

      (a)   The 5% administrative fee on Operating Costs described in the first
            sentence shall be eliminated.

      (b)   In no event shall the controllable components of Tenant's Share of
            Operating Costs and Real Property Taxes (e.g., components other than
            taxes, insurance, utility charges or snow removal) be increased for
            any given Lease Year by more than five percent (5%) over the prior
            Lease Year.

      (c)   "Operating Costs" shall not include costs incurred by Landlord for
            the replacement or repair of capital expense items which are
            Landlord's responsibility to maintain, such as foundation, walls,
            and roof structure (except maintenance of roof overlays).

                                                              AMEND TO LEASE 3.2

<PAGE>

      6. Waiver of Right to Terminate. Section 28(e) of the Lease is hereby
deleted in its entirety.

      7. Right of First Opportunity. Section 28(g) of the Lease is deleted in
its entirety and replaced with the following:

            (g)   Right of First Opportunity. Tenant shall have an ongoing right
                  of first opportunity (the "RFO") to lease any space on the
                  Fourth (4th) Floor of the Building which becomes available for
                  lease during the current Lease Term (the "RFO Space").
                  Tenant's rights to the RFO Space shall be subject to the
                  expansion and extension rights of other tenants of the
                  Building, and space will not be considered available if the
                  tenant then occupying the RFO Space agrees with Landlord to
                  extend the term of its lease with respect to all or a portion
                  of the RFO Space. Prior to leasing any RFO Space to a third
                  party, Landlord will first advise Tenant in writing (the "RFO
                  Notice") of the amount of any RFO Space which is available and
                  the terms and conditions under which Landlord is prepared to
                  lease the subject RFO Space to Tenant. If the RFO Notice is
                  given during the last thirty six (36) months of the current
                  Lease Term, Landlord may require that Tenant exercise the
                  Extension Option described in Section 3(c) of the Lease.
                  Tenant shall have ten (10) business days after receiving an
                  RFO Notice to notify Landlord in writing that Tenant desires
                  to lease all of the subject RFO Space under the terms and
                  conditions set forth in the RFO Notice. Such terms shall
                  reflect market terms in the local South King County submarket,
                  including but not limited to any and all concessions that
                  might be offered to any other prospective tenant, rental rate,
                  escalations, allowances, commissions and tenant rights. If
                  Tenant fails to timely notify Landlord of its interest in
                  leasing all of the subject RFO Space, Landlord shall be free
                  to lease the RFO Space to any other person or entity,
                  regardless of the length of time it takes Landlord to re-let
                  the RFO Space or the terms upon which it is ultimately re-let.
                  The RFO would again apply to any RFO Space which later becomes
                  available for lease only after re-letting and subsequent
                  expiration of the new lease.

      8. Survival of Extension Option. The Extension Option set forth in Section
3(c) of the Lease shall remain available to Tenant at the end of the Term, as
extended by the terms of this Agreement.

      9. Waiver of Recapture Right. Section 16(b) of the Lease is hereby deleted
in its entirety. In lieu of Landlord's Recapture Right, any rent payable to
Tenant under an approved sublease in excess of Base Rent (per square foot)
payable hereunder, or any additional consideration paid to Tenant arising from
an assignment or sublease approved by Landlord, shall be divided equally between
Landlord and Tenant, and Landlord's portion shall be payable by Tenant to
Landlord as additional rent under the Lease.

                                                              AMEND TO LEASE 3.2

<PAGE>

      10. Alterations by Tenant; Construction Labor Matters. Tenant acknowledges
that Landlord may condition its consent to any proposed alterations to the
Premises by Tenant pursuant to Section 11 of the Lease upon the management of
the construction of such alterations by Landlord or its property manager, for a
reasonable fee which shall not exceed five percent (5%) of the cost of the
project. Also notwithstanding any provision of the Lease to the contrary, Tenant
agrees that if, at any time during the Lease Term, it shall construct or alter
the improvements on or about the Premises, Tenant shall cause such construction
or alteration work to be performed by contractors who shall employ craft workers
who are members of unions that are affiliated with the AFL-CIO Building and
Construction Trades Department (the "LABOR COVENANT"). Tenant shall include the
Labor Covenant in each of its contracts for such construction or alteration
work. Tenant shall provide such evidence as Landlord may reasonably require,
from time to time during the course of such construction or alteration work,
that the Labor Covenant is being fully and faithfully observed and Tenant shall
include the obligation to provide such evidence in each contract entered into by
Tenant for such construction or alteration work. Tenant agrees that it shall
incorporate the foregoing requirements in any sublease of the Premises.

      11. Confidentiality. Landlord and Tenant shall keep the terms of the
Lease, as amended by this Agreement, confidential and shall not disclose the
material terms of the Lease, or disseminate or distribute any information
concerning the terms of the Lease to any third party without the prior written
consent of the non-disclosing party. Notwithstanding the foregoing, the
foregoing restrictions shall not preclude Tenant from making disclosures of
financial and other information required to be made by Tenant in connection with
financial or other reporting required of Tenant as a publicly traded company.
Furthermore, the foregoing shall not prohibit Landlord from providing such
information to prospective purchasers or lenders in connection with any proposed
sale or financing of the land and building. Finally, the foregoing shall not
preclude Landlord or Tenant from disclosing information regarding the terms of
the Lease with financial and legal advisors, accountants, investors, in
financial statements, or as required by law.

      12. No Other Changes. Except as expressly modified or amended by this
Agreement, all of the terms and conditions of the Lease shall remain unchanged
and in full force and effect. To the extent any of the terms and conditions of
the Lease conflict with any of the terms or conditions of this Agreement, this
Agreement shall control.

                                                              AMEND TO LEASE 3.2
