EXHIBIT 99.1
                                    AMENDMENT
                                     TO THE
                         WALLACE COMPUTER SERVICES, INC.
                      RETIREMENT PLAN FOR OUTSIDE DIRECTORS

         Effective as set forth below, this Amendment is made by WALLACE
COMPUTER SERVICES, INC. (the "Company"), a corporation organized and existing
under the laws of the State of Delaware.

         WHEREAS, the "Wallace Computer Services, Inc. Retirement Plan for
Outside Directors" (the "Plan") was previously established and maintained by the
Company for the benefit of its Outside Directors (as defined therein);

         WHEREAS, effective June 30, 2001, the board of directors of the Company
(the "Board") terminated the Plan with the result that (i) no individual who
became an Outside Director after such date was able to participate in the Plan
and (ii) no additional benefits accrued under the Plan with respect to Years of
Board Service (as defined therein) performed after June 30, 2001;

         WHEREAS, the Plan provides that benefits accrued under the Plan prior
to the effective date of its termination shall not be reduced on account of such
termination and shall be payable to each Outside Director who completes at least
five Years of Board Service upon the later of his or her attainment of age 60 or
retirement as an Outside Director;

         WHEREAS, in connection with its termination, the Board amended the Plan
to provide that, although no benefits will accrue with respect to Years of Board
Service after June 30, 2001, such Years of Board Service will continue to be
credited solely for purposes of determining whether an Outside Director has
completed at least five Years of Board Service in order to be eligible to
receive benefits accrued under the Plan prior to and through June 30, 2001;

         WHEREAS, the Board also amended the Plan to provide that,
notwithstanding any terms of the Plan to the contrary, individuals serving as
Outside Directors as of the effective date of the termination who attain the
mandatory retirement age of 70 years prior to completing five Years of Board
Service (the "Affected Outside Directors") will be eligible for benefits under
the Plan upon attainment of age 70 provided he or she serves on the Board until
he or she attains age 70;

         WHEREAS, in connection with the transaction contemplated by the
Agreement and Plan of Merger, dated as of January 16, 2003 (and as amended and
restated as of April 14, 2003), among Moore Corporation Limited ("Moore"), Moore
Holdings U.S.A. Inc., M-W Acquisition, Inc. and Wallace Computer Services, Inc.
(the "Merger Agreement"), Moore has offered three members of the Board the
opportunity to serve on the board of directors of Moore (as may be renamed Moore
Wallace Incorporated) (the "Moore Board") after the Effective Time (as defined
in the Merger Agreement);



         WHEREAS, as a result of the transaction contemplated by the Merger
Agreement, Mr. William J. Devers, Jr., one of the Affected Outside Directors,
shall retire as an Outside Director prior to his completion of five Years of
Board Service and prior to his attainment of age 70;

         WHEREAS, pursuant to Section 6.01 of the Plan, the Board at any time
may amend the Plan;

         WHEREAS, the Board desires to amend the Plan to recognize service on
the Moore Board by a former member of the Board for purposes of determining (i)
when an Outside Director shall commence receiving benefits accrued under the
Plan prior to and through June 30, 2001 and (ii) whether an Outside Director has
completed at least five Years of Board Service in order to be eligible to
receive benefits accrued under the Plan prior to and through June 30, 2001; and

         WHEREAS, the Board desires to further amend the Plan to provide that,
notwithstanding any terms of the Plan to the contrary, if Mr. Devers, as a
result of the transaction contemplated by the Merger Agreement, retires as an
Outside Director prior to his completion of five Years of Board Service and
prior to his attainment of age 70, he shall be eligible to receive benefits
accrued under the Plan prior to and through June 30, 2001, which benefits equal
$30,250, in accordance with Section 4 of the Plan, provided that he continues to
serve as an Outside Director until the Effective Time.

         NOW, THEREFORE, effective as of the Effective Time, the Plan is hereby
amended as follows:

         1.    Section 2.06 of the Plan is amended to add a new clause at the
