VANCOUVER, March 20, 2014 /PRNewswire/ -- Silver Wheaton Corp. ("Silver Wheaton" or the "Company") (TSX:SLW) (NYSE:SLW) announces the adoption by its Board of Directors (the "Board") of amendments to its by-laws to (i) add a provision that requires advance notice to the Company for director nominations, (ii) increase the quorum for shareholder meetings from 10% to 25%, and (iii) update of notice and signature provisions. AdvanceNoticeBy-LawforDirectorNominations The advance notice for director nominations provision would apply in circumstances where director nominations are made by shareholders of the Company, other than in connection with (i) the requisition of a shareholders' meeting, or (ii) a shareholder proposal, in each case made pursuant to the BusinessCorporationsAct ( Ontario) (the "Advance Notice Provision"). Among other things, the Advance Notice Provision fixes a deadline by which holders of record of common shares of the Company must submit director nominations to the Company prior to any annual or special meeting of shareholders and sets forth the information that a shareholder must include in the notice to the Company. In the case of an annual meeting of shareholders, notice to the Company must be made not less than 30 days and not more than 65 days prior to the date of the annual meeting; provided, however, that 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 was made, notice may be made not later than the close of business on the 10 th day following such public announcement. In the case of a special meeting of shareholders (which is not also an annual meeting), notice to the Company must be made no later than the close of business on the 15 th day following the day on which the first public announcement of the date of the special meeting was made. The Advance Notice Provision provides a clear process for shareholders to follow for director nominations and sets out a reasonable time frame for nominee submissions and the provision of accompanying information. The Advance Notice Provision should ensure that all shareholders 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 Provision should assist in facilitating an orderly and efficient meeting process.
