        <footnote id="F3">(FN 2, contd.) Mr. Peltz is a member of Trian Fund Management GP, LLC, which is the general partner of Trian Management, and therefore is in a position to determine the investment and voting decisions made by Trian Management on behalf of the Trian Entities. Accordingly, Mr. Peltz may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934) the shares beneficially owned by Trian Management and the Trian Entities. The Reporting Persons disclaim beneficial ownership of such shares except to the extent of their respective pecuniary interests therein and this report shall not be deemed an admission that the Reporting Persons are the beneficial owner of such securities for purposes of Section 16 or for any other purpose. Mr. Peltz is a director of the Issuer.</footnote>

        <footnote id="F7">One of the Trian Entities has entered into a series of privately negotiated back-to-back call and put transactions (the &quot;Options&quot;) with a counterparty through which it is entitled to the same economic gain or loss as if it has purchased the indicated shares.  More specifically, these transactions represent call options pursuant to which, on or prior to March 18, 2019 (the &quot;Exercise Date&quot;), the Trian Entity may acquire the number of shares set forth above at the exercise price set forth above (the &quot;Exercise Price&quot;).</footnote>
        <footnote id="F8">(FN 7, contd.) These call options may be exercised at any time, in whole or in part, on or prior to the Exercise Date. Simultaneously with the purchase of each call option, the Trian Entity also sold a put option to the counterparty for the same number of shares pursuant to which, if on the Exercise Date the call options have not been exercised by the Trian Entity and the Exercise Price is greater than the closing price of the shares on the Expiration Date (the &quot;Closing Price&quot;), the counterparty may require the Trian Entity to, at such person's election, either (i) pay the counterparty an amount in cash equal to the product of (a) the excess of the Exercise Price over the Closing Price and (b) the number of shares set forth above or (ii) acquire from the counterparty the number of shares set forth above at the Exercise Price.  With the exercise of any call option, a corresponding number of put options would be automatically terminated.</footnote>
        <footnote id="F9">(FN 8, contd.) As part of these transactions, the Trian Entity pays the counterparty a financing fee based on the number of days that the Options that it holds are outstanding, which fee is calculated using a monthly rate equal to one month LIBOR plus an applicable spread.  No premium was paid by either of the parties in connection with the Options. Until exercised, the Options do not give the Trian Entity any direct or indirect voting, investment or dispositive control over the underlying shares.</footnote>
