Mr. Michael Wheeler

Dear Michael:

      On behalf of Mercator Software, I am pleased to extend an offer of
employment to you as Senior Vice President Product Intensive Enterprises,
Worldwide. Your first day of employment will commence on or before October 8,
2001. Michael, I look forward to bringing you on board as a key member of our
executive leadership team. In addition to this worldwide role, you will be a key
member of Mercator's Operating Committee. Following are details of our offer to
you.

1. Position. You will start in a full-time position as Senior Vice President,
Product Intensive Enterprises, Worldwide reporting to me. By signing this
letter, you confirm to the Company that you are under no contractual or other
legal obligations that would prohibit you from entering employment with or
performing your duties for the Company.

2. Compensation and Employee Benefits. You will be paid a starting salary at the
rate of $250,000 annually, subject to an annual compensation review each year
beginning February 1, 2002, and payable in accordance with the Company's
standard payroll schedule. We will also offer you the opportunity to participate
in the Company's annual incentive bonus plan, under which you will be eligible
to earn, at par, a bonus of 100% of your base salary. The bonus payout is based
upon corporate and business unit performance and individual contribution in
meeting our objectives. The payout range is zero to 300%. Your 2001 bonus is
guaranteed to be no less than $200,000. It will be payable in the first quarter
of 2002, consistent with when other executives at this level are paid. As a
senior executive of the Company, you will be eligible to participate in the
company-sponsored benefits that the Company makes available to senior executives
(e.g., health insurance, dental insurance, etc.).

3. Options. You will be granted 300,000 options upon joining the company with an
exercise price equal to the fair market value on the date of grant. All of these
options will be subject to the attached vesting schedule.

longer publicly traded. The options that you acquire shall be subject to the
terms and conditions of the relevant stock option plan and stock option
agreement and other related agreements to be entered into by and between you and
the Company. In the event your employment is terminated by death or disability,
options to be vested within six (6) months of your death or disability will be
vested and be exercisable for the balance of their original term.

4. Sign-On Bonus. You will be given a sign-on bonus of $100,000 payable in two

7. Severance. If you are terminated for any reason other than for cause, you
will be entitled to twelve months' salary payable biweekly. In addition,
executive benefits for medical insurance and other executive perquisites will be
provided for six months.

If there is a change of control of the Company as defined in paragraph 3 herein,
within one year following a change of control of the Company, you may terminate
your employment with the Company if, during that one year period without your
written consent, there has occurred a significant diminution of, or assignment
to you of any duties inconsistent with your title, status, duties or
responsibilities as in effect as of the beginning of your employment with
Mercator. This right of termination can be exercised only if you give written
notice to the Company within thirty (30) days of the occurrence of the
significant diminution of, or assignment to you of any duties inconsistent with
your title, status, duties or responsibilities as in effect as of the beginning
of your employment with Mercator which you rely upon to terminate this
agreement. If you elect to terminate your employment pursuant to this provision,
upon such termination Mercator shall pay you twelve (12) months of base salary
in accordance with the Company's usual payroll practices.

8. Employment Relationship. The term of your employment with the Company is for
no specific period of time. Your employment with the Company will be "at will,"
meaning that either you or the Company may terminate your employment at any time
and for any reason, with or without cause with 30 days notice. This is the full
and complete agreement between you and the Company on this term. Although your
job duties, title, compensation and benefits, as well as the Company's personnel
policies and procedures, may change from time to time, the "at will" nature of
your employment may only be changed in an express written agreement signed by
you and the Company.
