How to Vote if Your Securities Trade on the Nasdaq Stockholm Exchange

The information in this section is of significance to shareholders who hold their securities ("Euroclear Registered Securities") through Euroclear Sweden AB, which securities trade on the Nasdaq Stockholm Exchange.  Shareholders who hold Euroclear Registered Securities are not registered holders of voting securities for the purposes of voting at the Meeting.  Instead, Euroclear Registered Securities are registered under CDS & Co., the registration name of the Canadian Depositary for Securities.  Holders of Euroclear Registered Securities will receive a Form of Proxy (the "Swedish Proxy") by mail directly from Computershare AB ("Computershare Sweden").  The Swedish Proxy cannot be used to vote securities directly at the Meeting.  Instead, the Swedish Proxy must be completed and returned to Computershare Sweden, strictly in accordance with the instructions and deadlines that will be described in the instructions provided with the Swedish Proxy.
