Supplemental Executive Retirement Plan

--------------------------------------------------------------------------------

        Whereas, DST Systems, Inc. ("DST") has adopted, effective January 1,
1999, the DST Systems, Inc. Supplemental Executive Retirement Plan (the "Plan")
which is administered by the Compensation Committee of the DST Board of
Directors; and

        Whereas, the Committee is authorized under the Plan to amend the Plan,
and the Committee has approved and authorized the following amendment;

        Now, Therefore, the Plan is hereby amended as follows:

1.Section 4.4 is hereby amended to read as follows:

"With respect to each Participant who has satisfied the requirements of
Section 4.3 for a Plan Year, the Committee or its delegate shall credit for such
Plan Year to such Participant's Account, as of March 31 next following the end
of such Plan Year, the sum of the following amounts:

(a)a percentage of Compensation, as defined for this purpose under the Qualified
Plan, determined in the sole discretion of the Committee to generally
approximate the percentage of employer contributions and forfeitures allocated
under the Qualified Plan for the Plan Year, multiplied by the Participant's
Compensation hereunder for the Plan Year in excess of the limit specified in
Section 4.3(a); and

(b)an additional percentage, if any, determined in the sole discretion of the
Committee, multiplied by the Participant's Compensation for such Plan Year.

Notwithstanding anything to the contrary, the allocation credit under this
Section 4.4 shall be at the discretion of the Committee. For a Plan Year, the
Committee may determine a zero percentage (0%) allocation credit under
(a) and/or (b) above. The formula of (a) above shall not be construed as an
obligation to exactly match the applicable percentage under the Qualified Plan."

2.A new Section 4.6 shall be added to read as follows:

"4.6(a)   A Participant may elect on a written election form to have his or her
account adjusted on the basis that amounts in the Participant's account had been
invested since the effective date of the Participant's latest dated written
election in any of the investment vehicles designated by the Committee or its
delegate, in such proportion as the Participant has designated on the written
election form.

(b)A Participant may change such election annually, to be effective March 31, by
written notice to DST's Corporate Secretary no later than ten days prior to
March 31.

(c)Any election made pursuant to this Section 4.6 shall remain in effect until
changed by the Participant as provided in Section 4.6 (b). If the Participant
makes no election pursuant to this Section 4.6, makes an election with respect
to only a part of the Participant's Account, or terminates an election, then all
portions of the Account not subject to an election pursuant to this Section 4.6
shall be credited with interest based on at the announced rate of return on an
investment or investments selected from time to time by this Committee or its
delegate. Subsequent to the Participant's Termination of Employment, the
Participant may

--------------------------------------------------------------------------------

change an election pursuant to this Section 4.6 with respect to amounts that are
not yet distributed pursuant to Section 5.3."

3.The amendment set forth herein shall be effective as of February 26, 2002.

4.The Plan, as amended herein, shall remain in full force and effect.
