Dear Mary:

This letter will amend our May 16, 2000 employment offer to you.

I am very pleased to confirm our offer of employment as Executive Vice
President, Corporate Controller, reporting to me. In this role you will be a
member of the Senior Management team and will work closely with Joe and me on
managing and establishing financial strategies for IRI.

Your initial salary will be at the rate of $180,000 annualized $6,923.08
bi-weekly (Band A). At IRI, we review all performance at one time each year with
performance increases, if earned, effective May 1. Your first performance
increase will be effective May 1, 2001 and will be prorated to your start date.

Consistent with our Management Incentive Plan (MIP), you will be eligible to
participate in the MIP effective on your first day of employment. Under the plan
guidelines established annually you will have a 28 percent bonus target. Your
final bonus will be based on Company performance and your personal performance.
For 2000 we will guarantee you 50 percent of your bonus which will equal
$25,200. Enclosed is a copy of the plan document.

As a senior executive of IRI you will be eligible to participate in our
Executive Deferred Compensation Program (EDCP). Specific details about the
program and enrollment materials will be sent to you on your one month
anniversary with IRI. Attached is an executive summary of the plan.

You will be granted 30,000 options of IRI stock with an exercise price no higher
than the closing price on the day you start work. These options have a vesting
schedule of one-third vested after two years and an additional third vested per
year for two years thereafter. To receive your stock options, you are required
to sign the attached non-competition and forfeiture agreement.

Effective upon your first day of full-time employment you will be eligible for
coverage under IRI's medical, dental and prescription drug plan. You will be
eligible to participate in our 401(k) plan on the first of the month following
the month you start. You will be entitled to three weeks vacation, pro-rated for
2000 based on your start date. Finally, if you are terminated for any reason
other than cause, we will provide you with six months severance and outplacement
services.

Employment with Information Resources, Inc. is contingent upon verification of
work eligibility.  This request is in compliance with the current Immigration

are legally obligated to tell you that this letter is not to be construed as an

you. I am sure you will find this new opportunity to be exciting, challenging
and rewarding. Please confirm your acceptance of this offer by signing and
returning one copy of this letter and the non-competition and forfeiture
