      At a meeting of the Board of Trustees of Mercer held on January 11, 2006 as part of the process the board utilizes to assess its performance and to identify opportunities to strengthen its effectiveness, the board considered certain changes to its corporate governance practices. As a result, the special meeting of shareholders in connection with the proposed conversion of Mercer to a corporate form scheduled for January 20, 2006 was adjourned to February 17, 2006 at 10:00 a.m. (Vancouver time) at The Terminal City Club, 837 West Hastings Street, Vancouver, British Columbia, Canada. The special meeting was adjourned in order to permit shareholders to consider amendments implemented by the board to the Articles and Bylaws of Mercer International Regco Inc., which will be the successor to Mercer under the proposed conversion, which eliminate the provision for a classified board of directors and provide a right for specified shareholders to call special meetings.
      This Proxy Statement/ Prospectus Supplement amends and supplements information in the Proxy Statement/ Prospectus primarily resulting from the decision of the Board of Trustees of Mercer to eliminate a classified board structure, often referred to as a staggered board, upon consummation of the conversion of Mercer to a corporation and to provide for the right of specified shareholders of Amalgamated Mercer to call special meetings. As a result of these amendments, all directors of Amalgamated Mercer will be elected annually and shareholders holding not less than 20% of the outstanding shares of Amalgamated Mercer shall be entitled to call special meetings.
      The Proxy Statement/ Prospectus is hereby amended as follows:
  Under “Risk Factors”, the risk factor “Washington law and Amalgamated Mercer’s Articles of Incorporation and Bylaws will preserve and add to certain existing anti-takeover provisions of Mercer” is amended to delete the reference therein to “a classified board”;
 
  Under “Adoption and Approval of Proposed Delaware Reincorporation— Description of Capital Stock and Governing Documents of Amalgamated Mercer and Relevant Laws— Anti-takeover Provisions— Articles of Incorporation of Amalgamated Mercer”, the second paragraph, which relates to the classified board of Amalgamated Mercer, is deleted in its entirety;
 
  Under “Adoption and Approval of Proposed Delaware Reincorporation— Comparison of Shareholder Rights”, the disclosure relating to “Classified Board” is amended and restated in its entirety as follows:
           
 
Board Structure
  Our Declaration of Trust provides that trustees shall be divided into three classes as nearly equal in number as possible. Each class of trustees is to be elected in succeeding years and trustees of each class are to hold office for a three-year term.   Under the Articles of Incorporation of Amalgamated Mercer, directors are elected annually and hold office until the next annual meeting of shareholders.
  Under “Adoption and Approval of Proposed Delaware Reincorporation—Comparison of Shareholder Rights”, the disclosure relating to “Special Shareholder Meetings” is amended and restated in its entirety as follows:
           
  Special Shareholder Meetings   Our Declaration of Trust provides that special meetings of shareholders may be called by the Chairman or the President, or by our trustees, and shall be called upon the written consent of shareholders holding not less than 20% of the outstanding Shares entitled to vote.   The Bylaws of Amalgamated Mercer provide that special meetings of shareholders may be called by a majority of the board of directors or the Chairperson of the board or by the Chief Executive Officer or by one or more shareholders holding shares in the aggregate entitled to cast not less than 20% of the votes at that meeting.
