<PAGE>

          4.6.1 Claim Notice. Any claim for indemnification must be made in
                ------------
writing, with notice delivered by the party seeking indemnification to the party
from whom indemnification is sought within the Indemnification Period. The claim
notice must specify in reasonable detail the nature and estimated amount of the
claim.

          4.6.2 Third-Party Claims. If the claim specified in the claim notice
                ------------------
relates to a third-party claim, the indemnifying person shall have 15 days after
its receipt of the claim notice to notify the indemnified person whether the
indemnifying person agrees that the claim is subject to indemnification pursuant
to this Section 4 and whether the indemnifying person elects to defend such
third-party claim at its own expense. If the claim relates to a third-party
claim that the indemnifying person elects to defend, the indemnifying person
shall control the defense or settlement of the claim and the indemnified person
shall not consent to the entry of any judgement or settle the claim and shall
reasonably cooperate with such defense or settlement. The indemnified person
shall, however, be entitled to participate in the defense or settlement of such
a third-party claim through its own counsel and at its own expense and shall be
entitled to approve or disapprove any proposed settlement that would impose a
duty or obligation on the indemnified person. If the indemnifying person does
not timely elect to defend a third-party claim, or if the indemnifying person
fails to conduct such defense with reasonable diligence, the indemnified party
may conduct the defense of, or settle, such claim at the risk and expense of the
indemnifying person. If the indemnifying person does not timely elect to defend
a third-party claim, it can later assume the defense of such claim. In such

                                      -12-
<PAGE>

event, the indemnifying person will reimburse the indemnified person for all
costs and expenses of defense (including attorneys" fees) incurred by the
indemnified person to defend the claim through the date the defense is assumed.

          4.6.3 Claims Other Than Third-Party Claims. If the claim does not
                ------------------------------------
relate to a third-party claim, the indemnifying person shall have 30 days after
receipt of the claim notice to notify the indemnified person in writing whether
the indemnifying person accepts liability for all or any part of the claim and
the method and timing of any proposed payment. If the indemnifying person does
not so notify the indemnified party, the indemnifying persons shall be deemed to
have accepted liability for all damages described in the claim notice if: (i)
the claim notice contains a statement that failure to respond will constitute
acceptance of liability; (ii) the indemnified person sends a second claim notice
by certified mail giving the indemnifying persons an additional 10 days in which
to respond and the indemnifying persons do not deny liability within the 10-day
period; and (iii) the indemnified person sends a copy of the second claim notice
to the indemnified person"s legal counsel named in this Agreement.

assigns.

     5.3  Amendment; Waiver. The provisions of this Agreement, or of any
agreement or document executed in connection with this Agreement, may be amended
or waived only in a written agreement signed by the party against which

breach under this Agreement shall not be construed as a waiver of any other or
any subsequent right or breach.

     5.4  Severability. If any portion of this Agreement is held to be invalid
by a court of competent jurisdiction, the remaining terms of this Agreement
shall remain in full force and effect to the extent possible.

be governed by the laws of the State of Washington (except for the choice of law
