If you are not a registered shareholder but you are a beneficial owner, please follow the instructions contained in the Circular. Notice and Access The Corporation is utilizing the notice and access mechanism (the “Notice and Access Provisions”) under Regulation 54-101 respecting Communication with Beneficial Owners of Securities of a Reporting Issuer and Regulation 51-102 respecting Continuous Disclosure Obligations, for distribution of proxy-related materials to registered and beneficial shareholders. The Notice and Access Provisions are a set of rules that allow reporting issuers to post electronic versions of proxy-related materials (including management information circulars) via the System for Electronic Document Analysis and Retrieval (“SEDAR”) and one other website, rather than mailing paper copies of such materials to shareholders. Shareholders will still receive a notice of meeting and a form of proxy. Shareholders with question about the Notice and Access Provisions can contact AST Trust Company (Canada) toll free at 1-888-433-6443 or by email at email@example.com. Shareholders may choose to receive a paper copy of the Circular by contacting AST Trust Company (Canada) toll free at 1-888-433- 6443 or by email at firstname.lastname@example.org. Electronic copies of the notice of the annual general and special meeting, the Circular and proxy form may be found on the Corporation’s SEDAR profile at www.sedar.com, the Corporation’s website at https://nouveaumonde.group/ and www.meetingdocuments.com/ASTCA/NOU as of May 28, 2021. The Corporation will not use the procedure known as “stratification” in relation to the use of Notice and Access Provisions. Stratification occurs when a reporting issuer using the Notice and Access Provisions provides a paper copy of the Circular to certain shareholders with the notice package. In relation to the Meeting, all shareholders will receive the required documentation under the Notice and Access Provisions, which will not include a paper copy of the Circular. Please review the Circular carefully and in full prior to voting as the Circular has been prepared to help you make an informed decision on the matters to be acted upon. The Circular is available under the Corporation’s profile on SEDAR at www.sedar.com. In order to ensure that a paper copy of the Circular can be delivered to a requesting shareholder in time for such shareholder to review the Circular and return a voting instruction form or proxy form prior to the deadline, it is strongly suggested that a shareholder ensure their request is received no later than on June 16, 2021.
