support to the agreed objectives.

ANNUAL INCENTIVE COMPENSATION COMPONENTS

1.   General Corporate Financial Objectives (80%)- Incentive compensation
     payment is subject to the achievement of the Company's overall financial
     objectives as defined by the 2001 Plan as approved by the Board of
     Directors. Should the Company not achieve these financial objectives,
     incentive compensation will be subjectively determined based upon your
     performance against your objectives and the Company's determination as to
     available incentive compensation funding.

     A. Achieve * in QRS Revenue (40%)- Paid at year-end on a pro rata basis
        from a minimum of 95% of plan and linearly thereafter with results to
        105% of plan. The payout rate doubles on revenue performance over

     B. Achieve * in QRS Earnings before Amortization of Goodwill (40%) -

        payout of $250,000 on this incentive.

2.   Personal Strategies and Objectives (20%) - Incentive compensation payment
     is subject to fulfillment of your specific objectives as CEO. While
     specific objectives have been noted above to measure your performance for
     incentive compensation, such measurements assume the overall performance of
     you and your direct reporting organization in the achievement of Company
     responsibilities, customer services levels, employee satisfaction and
     turnover, and the support of overall Company objectives, including the
     effective integration of Tradeweave and the repositioning of QRS under the
     Tradeweave brand with an integrated sales, marketing, and product plan.

LONG TERM INCENTIVES

As an officer of QRS, on January 2, 2001, you were entitled to convert certain
of your stock options into restricted QRS stock. For your stock options
converted into restricted shares, the restricted shares will have the same
provisions as your original stock options with the exception of a different
vesting schedule as outlined in your Restricted Stock Agreement (i.e.
acceleration, change of control protection, etc.). As CEO you were granted two
stock option grants of 15,000 shares each on March 8, 2000 with special vesting
provisions based on Company growth in 2000/2001 and 2000/2001/2002. The first of
these has been cancelled based on 2000 performance, and the second has been
converted to restricted stock with standard vesting provisions per Restricted
Stock Agreement.

 The Board of Directors may grant you more stock options in the future with the
approval of the Compensation Committee. The details of your current stock option
grants and restricted stock is attached in Addendum B.

This position is for no set period or term and just as you have the right to
resign your position, at any time, for any reason, QRS reserves the right to
terminate your employment, at any time, with or without cause, with or without
notice.

In the event your employment is terminated without cause, you will become
entitled to twelve (12) months of severance pay equal in the aggregate to your

accordance with the Company's standard payroll practices for current employees
and will be subject to the Company's collection of all applicable withholding

of your employment for any of the following reasons: (1) your failure to
substantially perform the material duties of your position with the Company
after a written demand for substantial performance is delivered to you by the
Company which specifically identifies the manner in which you have not
substantially performed those duties and which provides a reasonable period for
you to cure those deficiencies; (2) a material breach by you of your obligations
under any confidential or proprietary information agreements with the Company or
of any of your fiduciary obligations as an officer of the Company, (3) your
failure to follow in a material respect the reasonable policies or directives
established on an employee-wide basis by the Company, after written notice to
you indicating the policies or directives with which you are not in material
compliance, (4) any willful misconduct on your part having a material
detrimental effect on the Company or (5) any





unauthorized activity on your part which creates a material conflict of interest
between you and the Company after you have been provided with a reasonable
opportunity to refrain from that activity.

CHANGE OF CONTROL BENEFITS

A.       Should there occur a Corporate Transaction or a Change in Control (as
         those terms are defined in the Company's 1993 Stock Option/Stock
         Issuance Plan) and either (i) your employment is subsequently
         terminated without cause or (ii) you subsequently resign by reason of a
         material change in your base compensation, your targeted annual
         incentive compensation, your annual total target compensation, or your
         benefits (for this purpose, 15% will be deemed a material reduction), a
         material reduction in your duties or responsibilities, or a change in
         your principal place of employment by more than 50 miles, then you will
         be entitled to twelve (12) months of severance pay equal in the
         aggregate to your targeted total annual compensation and benefits at
         the level in effect at the time of your termination or resignation or
         (if greater) at the level in effect immediately prior to the Corporate
         Transaction or Change in Control. Your severance payments will be made
         in accordance with the Company's standard payroll practices for current
         employees and will be subject to the Company's collection of all
         applicable withholding taxes.

B.       This Paragraph B incorporates the special acceleration provisions of
         the Company's 1993 Stock Option/Stock Issuance Plan and accordingly
         applies to any and all options which you hold under the 1993 Plan at
         the time of a Corporate Transaction or Change in Control, including all
         options you currently hold and any options subsequently granted to you
         under the 1993 Plan. To extent any of those options are not to be
         assumed by the successor entity (or parent company) in the Corporate
         Transaction or otherwise continued in effect following the Change in
         Control or are not replaced with a cash incentive program which
         preserves the spread existing at the time of such Corporate Transaction
         or Change in Control on any shares for which your options are not
         otherwise at that time exercisable (the excess of the fair market value
         of those shares over the exercise price), then those options shall,
         immediately prior to the specified effective date for the Corporate
         Transaction or Change in Control, become exercisable for all the shares
         at the time subject to those options and may be exercised for all or
         any portion of those shares as fully vested shares. The acceleration of
         your options pursuant to this Paragraph B will not be subject to the
         limitation of Paragraph C below, even if the options which are not to
         be assumed or continued in effect or otherwise replaced with a cash
         incentive program were granted on or after December 24, 1997.

C.       This Paragraph C applies only to options granted to you under the
         Company's 1993 Stock Option/Stock Issuance Plan on or after December
         24, 1997. In the event of a Corporate Transaction or Change in Control
         during your period of employment with the Company, all of your post
         December 23, 1997 options will, immediately prior to the specified
         effective date for the Corporate Transaction or Change in Control,
         become exercisable for all the shares at the time subject to those
         options, whether or not those options are to be assumed or replaced
         with a cash incentive program and those accelerated options may be
         exercised for all or any portion of the option shares as fully vested
         shares. Such acceleration of your post December 23, 1997 options will,
         however, be limited to the extent and only to the extent necessary to
         assure that the option parachute payment attributable to the
         accelerated besting of those options would not constitute an excess
         parachute payment under Internal Revenue Code Section 280G(b).

D.       To the extent one of more of your options do not accelerate upon a
         Corporate Transaction or Change in Control by reason of the provisions
         of Paragraph B or the limitation of Paragraph C above, those options
         will continue to become exercisable in accordance with the original
         exercise





         schedule indicated in the respective grant notices for those options.
         However, should either (i) your employment be subsequently terminated
         without cause or (ii) you subsequently resign by reason of a material
         change in your base compensation, your targeted annual incentive
         compensation, your annual total target compensation, or your benefits
         (for this purpose, 15% will be deemed a material reduction), a material
         reduction in your duties or responsibilities, or a change in your
         principal place of employment by more than 50 miles, within twenty four
         (24) months following such Corporate Transaction or Chance in Control,
         then each of your post December 23, 1997 options, to the extent
         outstanding at that time but not otherwise fully exercisable, shall
         automatically accelerate and become immediately exercisable for all the
         option shares and may be exercised for any or all of those shares as
         fully vested shares at any time prior to the expiration or sooner
         termination of the option term. Your pre-December 24, 1997 options will
         not be subject to acceleration upon such an involuntary termination or
         resignation.

E.       Any of your options (whether granted before or after December 23, 1997)
         which are assumed by the successor entity (or parent company) in the
         Corporate Transaction or are otherwise continue in effect following the
         Change in Control transaction shall be appropriately adjusted to apply
         and pertain to the number and class of securities which would have been
         issued to you in the consummation of such Corporate Transaction or
         Change in Control had the options been exercised immediately prior to
         such event. Appropriate adjustments shall also be made to the option
         prices payable per share, provided the aggregate option prices payable
         shall remain the same.
