The debentures will bear quarterly interest at a rate of 8.7% per annum, will have a term to maturity of 8-1/2 years from the date of issue and be convertible at a price of U.S. $3.25 per share into common shares of Moore. If fully exercised, the conversion feature will entitle the holders of the debentures to acquire an approximately 19.7% interest in Moore, based on 88,456,940 common shares of Moore presently outstanding. The debentures will be redeemable at Moore's option at any time on or after the fifth anniversary of the issue date at a declining premium. In addition, Moore will have an obligation to make an offer to purchase the debentures and the right to redeem the debentures at a premium upon a change of control of Moore. Chancery Lane/GSC and its affiliates will be subject to a standstill arrangement which generally will limit their ownership interest in Moore to the greater of 19.9% of Moore's common shares on a fully-diluted basis or the ownership level of Moore's largest non-institutional shareholder, subject to certain exceptions. Chancery Lane/GSC has also agreed to certain restrictions on its right to transfer the debentures and its common shares in Moore. Moore will reimburse Chancery Lane/GSC for fees and expenses of up to US $7.5 million upon completion of the transaction. Completion of the financing, expected before year-end, is subject to acceptance of the private placement notice relating thereto by The Toronto Stock Exchange and certain other customary conditions. In connection with this investment, Moore has agreed to appoint Theodore Ammon and Alfred C. Eckert III, Chairman and CEO of GSC Partners and a former partner of Goldman, Sachs & Co., to the board of directors of Moore. As well, Moore has agreed to appoint two additional independent directors. Mr. Robert Burton, former Chairman and CEO of World Color Press, Inc., who will be appointed President and Chief Executive Officer of Moore upon completion of the financing, also will be appointed to the board of directors. W. Ed Tyler has resigned from the Company to pursue other interests. The investment by Chancery Lane/GSC in Moore represents the culmination of a review of Moore's strategic options initiated by the board of directors early in 2000.
