        <footnote id="F1">The price shown in Column 4 is a weighted average purchase price. The price range for the purchases is $69.095 to $69.25. The Reporting Persons undertake to provide upon request by the staff of the Securities and Exchange Commission, the Issuer or a security holder of the Issuer, full information regarding the number of shares purchased at each separate price.</footnote>
        <footnote id="F2">Trian Fund Management, L.P (&quot;Trian Management&quot;) serves as the management company for Trian Partners, L.P., Trian Partners Master Fund, L.P., Trian Partners Parallel Fund I, L.P., Trian Partners Strategic Investment Fund II, L.P., Trian Partners Strategic Investment Fund-A, L.P., Trian Partners Strategic Investment Fund-N, L.P., Trian Partners Strategic Investment Fund-D, L.P., Trian Partners Fund (Sub)-G, L.P., Trian Partners Strategic Fund-G II, L.P., Trian Partners Strategic Fund-G III, L.P., Trian Partners Strategic Fund-K, L.P. and Trian Partners Strategic Fund-C, Ltd. (collectively, the &quot;Trian Entities&quot;) and as such determines the investment and voting decisions of the Trian Entities with respect to the shares of the Issuer held by them.</footnote>
        <footnote id="F3">(FN 2, contd.) Mr. Garden 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. Garden 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.</footnote>
        <footnote id="F4">One of the Trian Entities has entered into a 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 November 20, 2018 (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;). 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</footnote>
        <footnote id="F5">(FN 4 contd.) 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. 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>
