          (a)   Effective Date. This Agreement shall be effective from July 18,
                --------------
1997 (the "Effective Date").

          (b)   Term. The Company agrees to continue the Employee's Employment,
                ----
and the Employee agrees to remain in Employment with the Company, from the
Effective Date until the earlier of:

          (i)   July 18, 2001; or

          (ii)  The date when the Employee's Employment terminates pursuant to
     Subsections 1 (d), (e), (f) or (g) below.

          (c)   Renewal. In the event that neither the Company nor Employee give
                -------
notice to the other party of an intention to terminate this Agreement at least
30 days prior to the date set forth in clause (i) of Subsection 1(b) hereof,
this Agreement shall be automatically renewed for a one-year term. This
Agreement shall thereafter be automatically renewed far successive one-year
terms in the absence of 30-day notice by either party to the contrary.

          (d)   Early Termination. Subject to Section 8, the Company may
                -----------------
terminate the Employee's Employment without Cause by giving the Employee 30
days' advance notice in writing. The Employee may terminate his Employment
without Good Reason by giving the Company 30 days' advance notice in writing.
The Employee's Employment shall terminate automatically in the event of his
death. Any waiver of notice shall be valid only if it is made in writing and
expressly refers to the applicable notice requirement of this Section 1.

          (e)   Cause. The Company may terminate the Employee's Employment at
                -----
any time upon reasonable notice for Cause. For all purposes under this
Agreement, "Cause" shall mean (i) a knowing failure by the Employee to comply
with the material policies of the Company, (ii) gross negligence of Employee
which results in a materially adverse impact to the Company, (iii) a breach of a
fiduciary duty to the Company, (iv) conviction of, or a plea of "guilty" or "no
contest" to, a felony or (v) demonstrable and repeated (x) failure to follow the
directions of the Company's Board of Directors (the

"Board") or (y) failure to perform his obligations, duties or responsibilities
hereunder, other than a failure resulting from the Employee's complete or
partial incapacity due to physical or mental illness or impairment.

          (f)   Good Reason. Employee may terminate his Employment at any time
                -----------
upon reasonable notice for Good Reason. For all purposes under this Agreement,
"Good Reason" shall mean (i) a substantial reduction in Employee's position or
authority at the Company, (ii) a more than 25 percent reduction in Base
Compensation or benefits, (iii) a failure to pay compensation payable hereunder
or (iv) the filing by the Company of bankruptcy proceedings.

          (g)   Disability. The Company may terminate the Employee's active
                ----------
Employment due to Disability by giving the Employee 30 days' advance notice in
writing. For all purposes under this Agreement, "Disability" shall mean that the
Employee, at the time notice is given, has performed substantially none of his
duties under this Agreement for a period of not less than three consecutive
months as the result of his incapacity due to physical or mental illness. In the
event that the Employee resumes the performance of substantially all of his
duties hereunder before the termination of his active Employment under this
Subsection 1(g) becomes effective, the notice of termination shall automatically
be deemed to have been revoked.

          (h)   Rights Upon Termination. Except as expressly provided in Section
                -----------------------
8, upon the termination of the Employee's Employment pursuant to this Section 1,

reimbursements described in Sections 3, 4, 5 and 6 for the period preceding the
effective date of the termination. The payments under this Agreement shall fully
discharge all responsibilities of the Company to the Employee.

consolidation, reorganization, sale or transaction are holders of more than 50
percent of the voting equity securities of the surviving corporation.

                --------------------
provide that any successor (whether direct or indirect and whether by purchase,
lease, merger, consolidation, liquidation or otherwise) to all or substantially
all of the Company's business and/or assets, by an agreement in substance and
form satisfactory to the Employee, will assume this Agreement and agree
expressly to perform this Agreement in the same manner and to the same extent as
the Company would be required to perform it in the absence of a succession. For
all purposes under this Agreement, the term "Company" shall include any
successor to the Company's business and/or assets which executes and delivers
the assumption agreement described in this Subsection 9(a) or which becomes
bound by this Agreement by operation of law.

                ---------------------

                ------------------------------
or understandings (whether oral or written and whether express or implied) which

or the Confidentiality, Inventions and Noncompetition Agreement dated as of
November 1, 1996 between Employee and the Company's predecessor in interest,

          (g)   Dispute Resolution Procedure.
                ----------------------------

                (i)     The parties agree that any dispute arising out of or
related to the Employment relationship between them, including but not limited
to common law or statutory claims for discrimination, wrongful discharge, breach
of contract, breach of public policy, physical or mental harm or distress,
unpaid wages or any other dispute, shall be resolved by binding arbitration,
except where the law specifically forbids the use of arbitration as a final and
binding remedy.

                (ii)    The party claiming to be aggrieved shall furnish to the
other party a written statement of the grievance identifying any witnesses or
documents that support the grievance and the relief requested or proposed.

                (iii)   If the other party does not agree to furnish the relief
requested or proposed, or otherwise does not satisfy the demand of the party
claiming to be aggrieved, the parties shall submit the dispute to nonbinding
mediation before a mediator to be jointly selected by the parties. The Company
will pay the cost of the mediation.

                (iv)    If the mediation does not produce a resolution of the
dispute, the parties agree that the dispute shall be resolved by final and
binding arbitration in Seattle, Washington. The parties shall attempt to agree
to the identity of an arbitrator, and, if they are unable to do so, the parties
agree to assignment of an arbitrator from Judicial Arbitration and Mediation
Services (JAMS). The arbitrator shall have the authority to determine whether
the conduct complained of in section (g)(ii) violates the rights of the
complaining party and, if so, to grant any relief authorized by law; provided,
however, that the employee and the Company agree that for violations of the
employee's trade secret obligations, the Company reserves the right to seek
preliminary injunctive relief in court in order to preserve the status quo or
prevent irreparable injury before the matter can be heard in arbitration. The
arbitrator shall not have the authority to modify, change or refuse to enforce
the terms of this Agreement. In addition, the arbitrator shall not have the
authority to require the Company to change any lawful policy or benefit plan.
The hearing shall be transcribed. The Company shall bear the costs of the
arbitration if the Employee prevails. If the Company prevails, the Employee will
pay half the cost of the arbitration or $500, whichever is less. Each party
shall be responsible for paying its own attorneys fees, unless the law provides
otherwise. Arbitration shall be the exclusive final remedy for any dispute
between the parties, and the parties agree that no dispute shall be submitted to
arbitration where the party claiming to be aggrieved has not complied with the
preliminary steps provided for in clauses (ii) and (iii) above.

                (v)     Employee acknowledges that he has carefully read this
arbitration agreement and understands it, and is entering into the agreement
voluntarily after a reasonable period of time to consider it and review it with
personal legal counsel. Employee also acknowledges he may be giving up the
opportunity to

                                       7
<PAGE>

bring claims before a court or jury, and does so in order to gain the benefits
of a speedy, impartial and cost-effective resolution procedure.

          (h)   No Assignment. The rights of any person to payments or benefits
                -------------
under this Agreement shall not be made subject to option or assignment, either
by voluntary or involuntary assignment or by operation of law, including
(without limitation) bankruptcy, garnishment, attachment or other creditor's
process, and any action in violation of this Subsection 10(h) shall be void.

          (i)   Attorney's Fees. Within 30 days of the execution hereof, the
                ---------------
Company agrees to reimburse the reasonable legal fees and expenses incurred by
Employee, not to exceed $2,500, in connection with the negotiation of this
Agreement and related transactions.

          IN WITNESS WHEREOF, each of the parties has executed this Agreement,
          ------------------
in the case of the Company by its duly authorized officer, as of the day and
year first above written.
