General By-Law

The Corporation's previous general by-laws were carried over from the amalgamation of Dynamic Fuel Systems Inc. (dynaCERT's predecessor entity) and Chancellor Enterprises Holdings Inc. on January 1, 2004.  Having regard to changes in the Corporation's corporate and management structure, certain amendments are warranted in order for the By-laws to more accurately reflect the Corporation's day-to-day operations and corporate administration.  The General By-Law must be approved by a majority of the votes cast at the Annual and Special Meeting in order to be properly approved and ratified by shareholders.

Advance Notice By-Law

The Advance Notice By‐Law establishes a framework for advance notice of nominations of directors by shareholders of the Corporation.  Among other things, the Advance Notice By‐Law fixes deadlines by which shareholders must submit a notice of director nominations to the Corporation prior to any annual or special meeting of shareholders where directors are to be elected, sets out the information that a shareholder must include in the notice and establishes the form in which the shareholder must submit the notice for that notice to be in proper written form. The Advance Notice By‐Law is intended to facilitate an orderly and efficient shareholder meeting process.  The Advance Notice By-Law must be approved by a majority of the votes cast at the Annual and Special Meeting in order to be properly approved and ratified by shareholders.
