Under changes to Canadian security rules in 2013, Canadian companies are no longer required to distribute physical copies of certain annual meeting related materials such as proxy circulars and annual financial statements to their investors. Instead, they may post electronic versions of such material on a website for investor review. This process, known as “notice-and-access”, directly benefits the company through a substantial reduction in both postage and material costs and helps the environment through a decrease in paper documents that are ultimately discarded.

Electronic copies of investor materials related to this meeting may therefore be found at and downloaded from www.meetingdocuments.com/ASTca/DSV. We have added features that will make searching for relevant sections and specific items a much easier process than finding this information in the paper versions of these documents.

You have several options to vote your proxy:

• Cast your vote on the Internet at www.astvotemyproxy.com

• Fax your signed proxy to 1-866-781-3111 or 416-368-2502

• Return your signed proxy by mail using the enclosed business reply envelope

• • Scan and send your signed proxy to proxyvote@astfinancial.com.

However you choose to vote, we must receive your vote by June 24, 2020 at 11:00am EDT. We also strongly encourage you to first review the matters under discussion for the meeting as described in our proxy circular at www.meetingdocuments.com/ASTca/DSV.

Should you wish to receive paper copies of investor materials related to this meeting, or have any questions, please contact us at 888-433-6443 or fulfilment@astfinancial.com prior to June 10, 2020 and we will send them within three business days, giving you sufficient time to vote your proxy. Following the meeting the documents will remain available at the website listed above for a period of one year.
