        <footnote id="F1">Fullerton Management Pte Ltd (&quot;Fullerton&quot;) may be deemed to beneficially own 219,695,826 shares through its wholly-owned subsidiaries, including Fullerton's direct wholly-owned subsidiary Cairnhill Investments (Mauritius) Pte Ltd (&quot;Cairnhill&quot;), which indirectly beneficially owns 214,529,160 shares through its wholly-owned subsidiaries. Except for Cairnhill, each of these subsidiaries beneficially owns less than 10% of the outstanding shares. Fullerton is a wholly-owned subsidiary of Temasek Holdings (Private) Ltd (&quot;Temasek&quot;), so Temasek may be deemed to beneficially own 219,695,826 shares.</footnote>
        <footnote id="F2">The filing of this statement shall not be deemed an admission that, for purposes of Section 16 of the Securities Exchange Act of 1934 or otherwise, any of the Reporting Persons is the beneficial owner of all such equity securities covered by this statement.</footnote>
