any reason or for no reason.  Similarly, Consilium is free to terminate our at-
will employment relationship with you at any time, with or without cause.
Thirty days notice of termination shall be provided by you or the Company in the
event that either elects to terminate the employment relationship for any reason
other than cause or transfer of control.  During such thirty day period you
shall continue to provide full and proper service to the Company in your then
current employment capacity unless the Company waives such notice period.

In the event of any dispute or claim relating to or arising out of our
employment relationship, this agreement or the termination of our employment
relationship, including but not limited to any claims of wrongful 
<PAGE>
 
termination or age or other discrimination, you and Consilium agree that all
such disputes shall be fully and finally resolved by binding arbitration
conducted by an employment lawyer selected by the American Arbitration
Association in San Jose, California and we waive our rights to have such
disputes or claims tried by a court or jury. However, we agree that this
mediation provision shall not apply to any dispute or claims relating to or
arising out of the misuse or misappropriation of Consilium's trade secrets or
proprietary or confidential information.

This letter agreement, the Company's standard employment proprietary rights
agreement, and other agreements referred to above, all of which you agree to
sign as a condition of your employment, define the terms of your employment and
supersede all prior agreements, both written and verbal.  This letter can not be
modified or amended except in a writing that is signed by an authorized
Consilium representative and you.

We are very happy to confirm your employment offer with this letter, and we look
forward to you joining Consilium.  Please indicate your acceptance of this offer
by signing one copy of this letter and returning it me.

Sincerely,

/s/ Linda Kato Ujihara

by Consilium during the pre-employment process.
