VANCOUVER, BRITISH COLUMBIA–(Marketwired – September 18, 2014) – Methanex Corporation (the “Company”) (TSX:MX)(NASDAQ:MEOH) announced today that its Board of Directors has approved the adoption of By-law No. 4. By-law No. 4 is a consolidation of By-laws Nos. 1, 2 and 3 and, in addition to certain amendments to the Company’s existing by-laws, includes the adoption of an advance notice by-law (the “Advance Notice By-Law”). By-laws Nos. 1, 2 and 3 have been repealed.

The Advance Notice By-law establishes a framework for advance notice of nominations of directors by shareholders of the Company. Among other things, the Advance Notice By-law fixes a deadline by which shareholders must submit a notice of director nomination to the Company prior to any annual or special meeting of shareholders at which directors are to be elected. The Advance Notice By-law also sets forth the information that a shareholder must include in the notice for it to be valid.

The Advance Notice By-law is similar to the advance notice by-laws adopted by many other Canadian public companies. The purpose of the Advance Notice By-law is to ensure that all shareholders, including those participating in a meeting by proxy rather than in person, receive adequate notice of the nominations to be considered at a meeting and can thereby exercise their voting rights in an informed manner. In addition, the Advance Notice By-law is intended to provide a reasonable framework for shareholders to nominate directors and should assist in facilitating an orderly and efficient meeting process.

In the case of an annual meeting of shareholders, notice to the Company must be given not less than 30 and no more than 65 days prior to the date of the annual meeting. In the event that the annual meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting is made, notice may be given not later than the close of business on the 10th day following the notice date.

In the case of a special meeting of shareholders (which is not also an annual meeting), notice to the Company must be given not later than the close of business on the 15th day following the day on which the first public announcement of the date of the meeting is made.

In addition to adopting the Advance Notice By-law, the Board of Directors of the Company has also adopted certain amendments to the Company’s existing by-laws. The principal purpose of these amendments is to ensure that the Company’s by-laws remain consistent with evolving corporate governance practices and the published guidelines of major proxy advisory firms. These amendments include increasing the quorum requirements for a directors’ meeting to a majority of directors, and removing the casting vote previously granted to the chairman of directors’ meetings. For shareholder meetings of the Company, the quorum has been increased to two or more persons holding or representing at least 25 per cent of the eligible vote, respectively.

By-law No. 4 is effective immediately. As required by the CBCA, shareholders of the Company will be asked to ratify and confirm the adoption of By-Law No. 4 at the next meeting of shareholders. The full text of By-law No. 4 has been filed under the Company’s profile at www.sedar.com.
