Notice-and-Access

As permitted by Canadian securities regulators, you are receiving this notification as the Corporation has decided to use the "notice-and-access" mechanism for delivery to the Shareholders of this notice of annual meeting of Shareholders, the management information circular of the Corporation dated March 13, 2020 prepared in connection with the Meeting and other proxy-related materials (the "Meeting Materials") as well as the annual audited consolidated financial statements of the Corporation for the financial year ended December 31, 2019, together with the independent auditor's report thereon, and related management's discussion and analysis (together, the "Financial Statements"). This year, the Corporation has adopted notice-and-access for both registered and non-registered Shareholders. Notice-and-access is a set of rules that allows issuers to post electronic versions of proxy-related materials online, via SEDAR and one other website, rather than mailing paper copies of such materials to Shareholders. Under notice-and-access, Shareholders still receive a proxy form or voting instruction form enabling them to vote at the Meeting. However, instead of paper copies of the Meeting Materials and of the Financial Statements, Shareholders receive this notice which contains information on how they may access the Meeting Materials and the Financial Statements online and how to request paper copies of such documents. The use of notice-and-access will directly benefit the Corporation by substantially

How to Request a Paper Copy of the Meeting Materials and of the Financial Statements

Before the Meeting

If your name appears on a share certificate, you are considered as a "registered Shareholder". If your Shares are listed in an account statement provided to you by an intermediary, you are considered as a "non-registered Shareholder". Whether you are a registered Shareholder or a non-registered Shareholder, you may request paper copies of the Meeting Materials and of the Financial Statements at no cost to you by contacting Broadridge Investor Communications Corporation ("Broadridge") by one of the following methods: on-line at www.proxyvote.com and entering the 16-digit control number located on your proxy or voting instruction form and following the instructions provided. Alternatively, you may submit a request by calling 1-877-907-7643 (toll free within North America) or 905-507-5450 (outside of North America), or by email to noticeandaccess@broadridge.com.

Please note that you will not receive another form of proxy or voting instruction form; please retain your current one to vote your Shares.

In any case, requests for paper copies should be received at least five (5) business days prior to the proxy deposit date and time, which is set for May 5, 2020 at 5:00 p.m. (Eastern Time) in order to receive the Meeting Materials and the Financial Statements in advance of such date and the Meeting date.
