After the Closing Date, the holders of the Class A Common Shares shall no longer as such be shareholders of the Corporation, shall cease to be entitled to dividends in respect of such shares and shall not be entitled to exercise any of the rights of the holders thereof and shall be limited to receiving the Final Purchase Option Exercise Price, the whole against presentation and surrender of the certificates representing such Class A Common Shares.

The Corporation shall not enter into any arrangement agreement or understanding, whether oral or in writing, that is inconsistent with or limits or impairs the rights of the Majority Holder and the obligations of the Corporation hereunder, including, without limitation, any arrangement, agreement or understanding which imposes any obligation upon the Corporation or deprives the Corporation of any material rights, as a consequence of the exercise of the Purchase Option or the acquisition of the outstanding Class A Common Shares pursuant thereto. In addition, until the Purchase Option Expiration Time, any resolution to liquidate, dissolve or wind-up the Corporation will confer upon the holders of Class B Common Shares a right to vote and such Class B Common Shares will carry a number of votes equal to the total number of votes carried by the Class A Common Shares at the time outstanding. 3.17 Until the Purchase Option Expiration Time, no alteration, change or amendment to the Articles of Incorporation of the Corporation, as amended or restated from time to time, that would alter the rights of the Majority Holder under the Purchase Option, authorize the creation or issuance of any additional class or series of shares, result in the voluntary dissolution, liquidation or winding-up of the Corporation, effectuate an amalgamation or a consolidation of the Corporation with or into any other corporation or entity, alter the right of the Majority Holder to elect one director, or amend this paragraph 3.17 shall have any force or effect until it has been approved by a majority of not less than two-thirds (2/3) of the votes cast by the holders of the Class B Common Shares, voting separately as a class at a meeting of such holders specially called for that purpose, or by a resolution in writing signed by all the holders of the Class B Common Shares, in addition to any other approval required by the Act. 11 B) Section 4 of the articles of incorporation be and the same is hereby deleted and replaced by the following: 4 - RESTRICTIONS, IF ANY, ON SHARE TRANSFERS None.
