     will be prepared for the records of the Corporation and Securities Bureau.
     The original copy will be returned to the address appearing in the box
     above as evidence of filing.

     Since this document must be microfilmed, it is important that the filing be
     legible. Documents with poor black and white contrast, or otherwise
     illegible, will be rejected.

2.   This document is to be used pursuant to sections 641 through 643 of the Act
     for the purpose of restating the articles of incorporation of a domestic
     profit corporation. Restated articles of incorporation are an integration
     into a single instrument of the current provisions of the corporation's
     articles of incorporation, along with any desired amendments to those
     articles.

3.   Restated articles of incorporation which do not amend the articles of
     incorporation may be adopted by the board of directors without a vote of
     the shareholders. Restated articles of incorporation which amend the
     articles of incorporation require adoption by the shareholders. Restated
     articles of incorporation submitted before the first meeting of the board
     of directors require adoption by all of the incorporators.

     be stated.

7.   If the restated articles are adopted before the first meeting of the board
     of directors, this document must be signed in ink by all of the
     incorporators. If the restated articles merely restate and integrate the
     articles, but do not amend, this document must be signed in ink by an
     authorized officer or agent of the corporation. If the restated articles
     amend the articles of incorporation, this document must be signed in ink by
     the president, vice-president, chairperson, or vice-chairperson.
