SEC 1913 (02-02) IMPORTANT NOTICE TO DIRECTORS AND EXECUTIVE OFFICERS OF WALLACE COMPUTER SERVICES, INC. CONCERNING THE BLACKOUT PERIOD UNDER THE THE WALLACE PROFIT SHARING AND RETIREMENT PLAN AND THE WALLACE COMMERCIAL PRINT 401(K) RETIREMENT PLAN (THE "PLANS") APRIL 11, 2003 1. This notice is being provided to you to inform you that in connection with the proposed merger of Wallace Computer Services, Inc. ("Wallace") with a wholly owned subsidiary of Moore Corporation Limited ("Moore"), as a result of which Wallace will become a wholly owned subsidiary of Moore (the "Merger"), each of the Wallace Stock Funds under the Wallace Profit Sharing and Retirement Plan and the Wallace Commercial Print 401(k) Retirement Plan (the "Plans") will be converted into a stock fund primarily holding Moore common shares (the "Moore Wallace Stock Fund") as soon as administratively practicable after the effective time of the consummation of the Merger (the "Effective Time"). 2. In connection with this proposed Merger, participants in the Plans will be temporarily unable to transfer any portion of their account balances either into or out of the Wallace Stock Fund. Moreover, participants with all or a portion of their account balances invested in the Wallace Stock Fund will be temporarily unable to receive a distribution of all or such portion of their account balance. Finally, participants who have elected to have all or a portion of their contributions under the Plans invested in the Wallace Stock Fund will be temporarily suspended from investing new contributions in the Wallace Stock Fund. This period during which participants will temporarily be unable to exercise these rights otherwise available to them under the Plans is called a "blackout period." 3. The blackout period for the Plans is expected to begin during the week of May 4, 2003 and is expected to end the week of May 18, 2003. During these weeks, you can determine whether the blackout period has started or ended by calling Lewis Jacobson or Chris Gicela of the Wallace Retirement Plans department toll-free at 1-877-799-9350. 4. Pursuant to Section 306(a) of the Sarbanes-Oxley Act of 2002, as a director or executive officer of Wallace, during this blackout period you will not be permitted to purchase, sell or otherwise acquire or transfer, directly or indirectly, any Wallace common shares to the extent such shares are, or were, acquired in connection with your service or employment as a director or executive officer of Wallace (including, but not limited to, any Wallace common shares you hold in order to comply with share ownership guidelines). Moreover, if you are or become a director or executive officer of Moore after the Effective Time, for the duration of the blackout period you will similarly be prohibited from purchasing, selling or otherwise acquiring or transferring, directly or indirectly, any Moore common shares which you receive in respect of Wallace common shares acquired in connection with your service or employment as a director or executive officer of Wallace. While the receipt of Moore common shares in exchange for Wallace common shares in connection with the Merger is exempt from this prohibition, if you are contemplating any other transactions involving Wallace common shares or Moore common shares, please contact James Benak, General Counsel, Wallace Computer Services, Inc. 2275 Cabot Drive, Lisle, IL, 60532-3630, (630) 588-6475 for more information on whether such shares are, or were, "acquired in connection with your service or employment as a director or executive officer of Wallace." 5.
