 a proxyholder to vote Common Shares in favor of the Arrangement Resolution) is entitled, in addition to any other rights the holder may have, to exercise Dissent Rights and to be paid the fair value of the Common Shares held by the
holder, determined, notwithstanding anything to the contrary contained in Chapter XIV – Division I of the QBCA, as of the close of business on the day before the Arrangement Resolution was adopted at the Special Meeting. Only Registered
Shareholders may exercise Dissent Rights. Beneficial Shareholders who wish to exercise Dissent Rights should be aware that they may do so only through the registered owner of their Common Shares. Accordingly, a non-registeredowner of Common Shares desiring to exercise Dissent Rights must make arrangements for the Common Shares beneficially owned by that holder to be registered in the name of the Shareholder prior to the time the Dissent Notice is required to be received by the Company or, alternatively, make arrangements for the registered holder of such Common Shares to exercise Dissent Rights on behalf of the holder. In such case, the Dissent Notice should specify the number of Common Shares. A Dissenting Shareholder may only dissent with respect to all the Common Shares held on behalf of any one beneficial owner and registered in the name of the Dissenting Shareholder, subject to such Dissenting Shareholder exercising all the voting rights carried by such Common Shares against the Arrangement Resolution. Note that Chapter XIV – Division I of the QBCA, the text of which is attached as Annex C to this Circular and Proxy Statement, sets forth special provisions which are required to be followed with respect to the exercise of Dissent Rights by Beneficial Shareholders (or non-registeredShareholders).
