ITEM 11. TEMPORARY SUSPENSION OF TRADING UNDER REGISTRANT'S EMPLOYEE BENEFIT
PLANS.

         On April 11, 2003, Wallace Computer Services, Inc. ("Wallace") filed a
Current Report on Form 8-K (the "Initial Form 8-K") in connection with a
temporary suspension of rights of participants in the Wallace Profit Sharing and
Retirement Plan and the Wallace Commercial Print 401(k) Retirement Plan (the
"Plans") known as a "blackout period". In connection with the proposed merger of
Wallace with a wholly owned subsidiary of Moore Corporation Limited (the
"Merger"), each of the Wallace Stock Funds under the Plans will be converted
into a stock fund primarily holding Moore common shares as soon as
administratively practicable after the effective time of the consummation of the
Merger (the "Effective Time"). The Initial Form 8-K stated that the blackout
period for the Plans was expected to begin during the week of May 4, 2003 and
was expected to end the week of May 18, 2003. These dates have been adjusted to
reflect the expected date of the Effective Time. The blackout period for the
Plans is now expected to begin during the week of May 11, 2003 and is expected
to end the week of May 25, 2003.

                  Pursuant to the requirements of the Securities Exchange Act of
