Dear Mike:

This letter sets forth our agreement regarding your resignation from Marcam

         1. You will step down as President and Chief Executive Officer and an
officer of the Company, as well as an officer or director of any subsidiary of
the Company, effective November 17, 1997. You will remain an employee of the
Company through January 27, 1998 at which time you will resign as an employee of
the Company (the "Resignation Date"). You will remain a director of the Board of
the Company through a period to be mutually agreed.

         2. From November 17, 1997 through the Resignation Date, you will
receive a base salary of $9,230.77 bi-weekly and remain eligible to participate
in the Company's then current benefits. You will not be eligible for any bonus
for performance during the Company's 1998 fiscal year. As of the Resignation
Date, your salary will cease and any entitlement you have or might have had
under any Company-provided bonus plan or benefit plan, program or practice will
terminate, except as required by federal or state law or as otherwise described
in this letter. The Resignation Date shall be treated as your "qualifying event"
under the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), and
you will receive COBRA information under separate cover.

         3. On the date you sign this letter agreement, you will be granted an
incentive stock option to purchase 25,000 shares of Common Stock of the Company
under the Company's 1997 Stock Plan, at an exercise price equal to the fair
market value of the Common Stock on the date of the grant, and which will be
100% vested immediately.

         4. As of the Resignation Date, all stock options (the "Options")
granted to you during your employment but not yet vested will be forfeited in
accordance with their terms. Any options granted to you during your employment
and vested as of the Resignation Date shall be governed by paragraph 5 of the
letter agreement dated June 10, 

<PAGE>

1997 by and among you, Marcam Corporation and the Company (the "Letter 
Agreement").

         5. As of the Resignation Date, as a non-employee director, you will be
eligible to receive the then current cash compensation for each Board meeting
attended (currently $1000 per meeting) and to participate in the Company's
Non-Employee Director Stock Option Plan (the "Directors' Plan") under which you
will (i) automatically be granted an option to purchase 10,000 shares of Common
Stock of the Company in accordance with the Directors' Plan and (ii) be eligible
to automatically be granted an option to purchase 1,500 shares of Common Stock
of the Company on January 1 of each year as long as you are a current
non-employee director of the Company on such date.
