        <footnote id="F1">Pursuant to Rule 12g-3(a) under the Exchange Act, Ovintiv is the successor issuer to Encana Corporation (&quot;Encana&quot;).</footnote>
        <footnote id="F2">The shares of Common Stock were purchased in Canadian dollars at a price of CAD $5.556 per share. The price has been converted to U.S. dollars using the Bank of Canada exchange rate on the transaction date.</footnote>
        <footnote id="F3">On January 24, 2020, Encana completed a corporate reorganization (the &quot;Reorganization&quot;) which included, among other things, a share consolidation on the basis of one post-consolidation share for each five pre-consolidation shares (the &quot;Share Consolidation&quot;) and Ovintiv Inc. ultimately acquiring all of the issued and outstanding common shares of Encana in exchange for shares of Ovintiv on a one-for-one basis. The amount of securities beneficially owned reflect completion of the Reorganization, including the Share Consolidation.</footnote>
