The following constitutes Amendment No. 4 to the Schedule 13D filed by the undersigned ("Amendment No. 4"). This Amendment No. 4 amends the Schedule 13D as specifically set forth herein. Capitalized terms used herein and not otherwise defined in this Amendment No. 4 have the meanings set forth in the Schedule 13D.

The 8,736,867 Shares reported herein by the Reporting Person were acquired at an aggregate purchase price of approximately $171.4 million. Such Shares were acquired with investment funds in accounts managed by JANA and margin borrowings described in the following sentence. Such Shares are held by the investment funds managed by JANA in commingled margin accounts, which may extend margin credit to JANA from time to time, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account. The margin accounts bear interest at a rate based upon the broker's call rate from time to time in effect. Because other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Shares reported herein.

(a) The aggregate percentage of Shares reported to be beneficially owned by the Reporting Person is based upon 161,070,907 Shares outstanding as of January 29, 2021, as reported in the Issuer's Quarterly Report on Form 10-Q for the quarterly period ended January 1, 2021 filed with the Securities and Exchange Commission on February 5, 2021.

As of the close of business on the date hereof, JANA may be deemed to beneficially own 8,736,867 Shares, representing approximately 5.4% of the Shares outstanding.

(b) JANA has sole voting and dispositive power over 8,736,867 Shares, which power is exercised by the Principal.

(c) Information concerning transactions in the Shares effected by the Reporting Person since the filing of Amendment No. 3 to the Schedule 13D is set forth in Exhibit E hereto and is incorporated herein by reference. All of the transactions in Shares listed hereto were effected in the open market through various brokerage entities.
