to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (the &#147;MLI&#148;). On August&nbsp;29, 2019, Canada deposited its instrument of ratification with the Depositary of the MLI, and the MLI entered into force in
Canada on December&nbsp;1, 2019. Where applicable, the MLI provides that a benefit under an applicable tax treaty or convention with Canada (such as a reduced rate of Canadian withholding tax) shall not be granted in respect of an item of income or
capital (including dividends) if it is reasonable to conclude, having regard to all relevant facts and circumstances, that obtaining the benefit was one of the principal purposes of any arrangement or transaction that resulted directly or indirectly
in that benefit, unless it is established that granting that benefit in the circumstances would be in accordance with the object and purpose of the relevant provisions of the tax treaty or convention. Where applicable, the MLI may also limit or deny
other benefits under applicable tax treaties or conventions with Canada in other circumstances, including to a resident of another jurisdiction unless that resident is a &#147;qualified person&#148; as defined in the MLI. The MLI applies to
Canada&#146;s tax treaties and conventions with countries which have also deposited their instruments of ratification with the Depositary and which have mutually indicated that their treaties or conventions with Canada will be covered by the MLI. As
of the date hereof, the United States has not ratified the MLI. </P>
