About Notice and Access

Exco has elected to use the notice-and-access rules adopted by Canadian Securities Administrators in an effort to be more environmentally friendly and reduce printing and mailing costs by reducing the volume of materials that must be physically mailed to our shareholders. Exco will instead post the information circular and any additional materials online. Shareholders will receive a notice package which includes a form of proxy and may choose to receive a hard copy of the information circular. Exco will not use procedures known as “stratification”. Stratification occurs when a reporting issuer using the notice-and-access provisions provides a paper copy of the information circular to some shareholders with the notice package. In relation to the Meeting, all Exco shareholders will receive the required documentation under the notice-and-access provisions, which will not include a paper copy of the information circular. The Meeting material can be viewed online at https://docs.tsxtrust.com/2086 or under Exco’s profile on SEDAR+ (www.sedarplus.ca).
