Vast Provides Corporate Governance Update

CALGARY, ALBERTA--(Marketwired - June 5, 2013) - Vast Exploration Inc. (TSX VENTURE:VST) has amended its by-laws to adopt a new policy that requires advance notice to Vast for nominations of directors other than by management, through a requisition for a meeting or by way of a shareholder proposal.

Among other things, the policy 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 for the notice to be in proper written form.

In the case of an annual meeting of shareholders, notice to the company must be made not less than 30 nor more than 65 days prior to the date of the annual meeting, provided 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 tenth 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 not 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 new policy is intended to: (i) facilitate an orderly and efficient annual general or special meeting process; (ii) ensure that all shareholders receive adequate notice of the director nominations and sufficient information regarding all director nominees; and (iii) allow shareholders to register an informed vote after having been afforded reasonable time for appropriate deliberation.

The by-law amendment and policy is effective immediately and will be placed before Vast's shareholders for approval at Vast's annual general and special meeting of shareholders scheduled to be held on July 24, 2013.

The full text of the policy is available under Vast's profile at www.sedar.com.
