            (b) Executive is entitled to extend coverage under any group
health plan in which Executive and Executive's dependents are enrolled at the
time of termination of employment under the COBRA continuation laws for the

equivalent to the reasonably estimated cost Executive may incur to extend for

                                      2
<PAGE>

payment in an amount equivalent to the reasonably estimated cost Executive
may incur to extend for a period of 24 months under the COBRA continuation
laws Executive's group health and dental plan coverage in effect at the time
of termination. Executive may use this payment, as well as any payment made
under Section 3.2(a), for such COBRA continuation coverage or for any other
purpose.

Executive will be entitled to receive an amount equal to the Executive's full
target bonus amount for the year and any partial year period in which the
Termination occurred under any cash incentive plans in effect at the time of
a Termination of Executive's Employment. For example, if there is a target
annual bonus amount and a target semi-annual bonus amount in place, the
Executive will be entitled to receive the full annual target bonus amount for
the year in which the Termination occurred and the full semi-annual target
bonus amount for the six-month period in which the Termination occurred. The
amount payable pursuant to this section shall be paid on the same date that
the Section 3.2(a) payment is payable.

            (d) All stock options granted to the Executive under the
Company's 1995 Stock Incentive Plan or any other equity plan shall become
immediately exercisable in full in accordance with the applicable provisions
of the relevant option agreement and plan.

        3.3 Notwithstanding the foregoing, if the total payments and benefits
to be paid to or for the benefit of Executive under this Agreement would
cause any portion of those payments and benefits to be "parachute payments"
as defined in section 280G(b)(2) of the Internal Revenue Code of 1986, as
amended, or any successor provision, the total payments and benefits to be
paid to or for the benefit of Executive under this Agreement shall be reduced

to constitute "parachute payments."

        4.1 WITHHOLDING. All payments provided for in this Agreement are
subject to applicable withholding obligations imposed by federal, state and
local laws and regulations.

        4.2 OFFSET. The amount of any payment provided for in this Agreement

of any compensation earned by Executive as the result of employment by
another employer after termination.

under any other agreement with the Company in effect at the time of
termination (including but not limited to any employment agreement, but
excluding for this purpose any stock option agreement that may provide for
accelerated vesting or related benefits upon the occurrence of a change in
control), the benefits provided in this Agreement shall not be payable to
Executive. Executive may, however, elect to receive all of the benefits
provided for in this Agreement in lieu of all of the benefits provided in all
such other agreements. Any such election shall be

                                      3

some benefits from one agreement and other benefits from this Agreement.

           (a) a significant reduction by the Company or the surviving company
       in Executive's base pay as in effect immediately prior to the Change of
       Control, other than a salary reduction that is part of a general salary
       reduction affecting employees generally:

           (b) a significant reduction by the Company or the surviving company
       in total benefits available to Executive under cash incentive, stock
       incentive and other employee benefit plans after the Change of Control
       compared to the total package of such benefits as in effect prior to the
       Change of Control;

           (c) The Company or the surviving company requires Executive to be
       based more than 50 miles from where Executive's office is located
       immediately prior to the Change of Control except for required travel on
       company business to an extent substantially consistent with the business
       travel obligations which Executive undertook on behalf of the Company
       prior to the Change of Control; or

           (d) The assignment of Executive to a different title, job or
       responsibilities that results in a material decrease in the level of
       responsibility of Executive with respect to the surviving company after
       the Change of Control when compared to Executive's level of
       responsibility for the Company's operations prior to the Change of
       Control; PROVIDED, that Good Reason shall not exist if Executive
       continues to have substantially the same or a greater general level of
       responsibility with respect to the former operations of the Company after
       the Change of Control as Executive had prior to the Change of Control
       even if the former such operations are a subsidiary or division of the
       surviving company.

    6.2  CAUSE.  Termination of Executive's Employment for "Cause" shall mean
termination upon (a) the willful and continued failure by Executive to

physical or mental illness) after a demand for substantial performance is
delivered to Executive by the Board of Directors, the Chief Executive Officer
or the President of the Company which specifically identifies the manner in
which the Board of Directors or the Company believes that Executive has not
substantially performed Executive's duties or (b) the willful engaging by
Executive in illegal conduct which is materially and demonstrably injurious
to the Company. No act, or failure to act, on Executive's part shall be
considered "willful" unless done, or omitted to be done, by Executive without
reasonable belief that Executive's action or omission was in, or not opposed
to, the best interests of the Company. Any act, or failure to act, based upon
authority given pursuant to a resolution duly adopted by the Board of
Directors shall be conclusively presumed to be done, or omitted to be done,
by Executive in the best interests of the Company.

         (a) The shareholders of the Company approve one of the following:

             (i) Any merger or statutory plan of exchange involving the

           surviving corporation or pursuant to which Common Stock would be
           converted into cash, securities or other property, other than a
           Merger involving the Company in which the holders of Common Stock
           immediately prior to the Merger continue to represent more than
           50 percent of the voting securities of the surviving corporation
           after the Merger; or

              (ii) Any sale, lease, exchange, or other transfer (in one
           transaction or a series of related transactions) of all or
           substantially all of the assets of the Company.

           (b) A tender or exchange offer, other than one made by the Company,
       is made for Common Stock (or securities convertible into Common Stock)
       and such offer results in a portion of those securities being purchased
       and the offer or after the consummation of the offer is the beneficial
       owner (as determined pursuant to Section 13(d) of the Securities Exchange
       Act of 1934, as amended (the "Exchange Act")), directly or indirectly, of
       securities representing more than 50 percent of the voting power of

       a tender offer or exchange offer described in (b) above, a Change of
       Control shall not take place until the conclusion of such offer.

Notwithstanding anything in the foregoing to the contrary, no Change of Control

Executive, acquiring, directly or indirectly, securities representing
20 percent or more of the voting power of outstanding securities of the Company.

        6.4 DISABILITY. "Disability" means Executive's absence from
Executive's full-time duties with the Company for 180 consecutive days as a
result of Executive's incapacity due to physical or mental illness, unless
within 30 days after notice of termination by the Company following such
absence Executive shall have returned to the full-time performance of
Executive's duties. This Agreement does not apply if the Executive is
terminated due to Disability.

    7.  SUCCESSORS; BINDING AGREEMENT.  This Agreement shall be binding on and

and governed by the laws of the State of Oregon

    10.  AMENDMENT.  No provision of this Agreement may be modified unless

    11.  SEVERABILITY.  If any of the provisions or terms of this Agreement
shall for any reason be held invalid or unenforceable, such invalidity or
unenforceability shall not affect any other terms of this Agreement, and this
Agreement shall be construed as if such unenforceable term had never been
contained in this Agreement.
