investment opportunities available to the Reporting Persons, conditions in

Reporting Persons may in the future take actions with respect to its
investment position in the Issuer as it deems appropriate, including, without
limitation, purchasing additional Common Stock or other instruments that are

     ValueAct Master Fund entered into the Master Confirmation and the
Forward Transactions in accordance with the trade details set forth in Item 5
(c) hereto.

     Pursuant to each Forward Transaction, ValueAct Master Fund will be
obligated either to (i) purchase from the Counterparty, on the Settlement
Date of August 9, 2018 with respect to 4,859,200 of the Forward Transactions
and February 12, 2020 with respect to 15,165,268 of the Forward Transactions
(or earlier if such Forward Transaction is terminated early in accordance
with its terms), the Number of Forward Shares with respect to such Forward
Transaction (or the applicable portion thereof to which any such early
termination applies) at a price equal to the Forward Price, as set forth in
Item 5 (c) hereto ("Physical Settlement"), or (ii) pay to the Counterparty
the product of (x) the Number of Forward Shares multiplied by (y) the Forward
Price minus the volume-weighted average price per share for on August 9, 2018
and February 12, 2020 (or earlier if such Forward Transaction is terminated
early in accordance with its terms), if such amount is positive, or receive
from the Counterparty the absolute value of such amount if such amount is
negative ("Cash Settlement").

     A financing charge will be added to the amount, if any, owing by
ValueAct Master Fund to the Counterparty pursuant to Cash Settlement or
Physical Settlement or subtracted from the amount, if any, owing by the
Counterparty to ValueAct Master Fund pursuant to Cash Settlement, and an
amount equal to the value of any dividends paid in respect of the Number of
Forward Shares for which the record date occurs during the term of the
applicable Forward Transaction will be subtracted from the amount, if any,
owing by ValueAct Master Fund to the Counterparty pursuant to Cash Settlement
or Physical Settlement or added to the amount, if any, owing by the
Counterparty to ValueAct Master Fund pursuant to Cash Settlement.

     Under the terms of the Master Confirmation, ValueAct Master Fund shall
have the option to elect Physical Settlement or Cash Settlement for the
Forward Transactions, but Physical Settlement, which is the default
settlement method, shall only be available if the receipt of such shares by
ValueAct Master Fund would not violate the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Condition"). If, on the
Settlement Date, the HSR Condition is not satisfied and ValueAct Master Fund
has not elected Cash Settlement, the Settlement Date automatically will be
postponed until the HSR Condition is satisfied.

     ValueAct Master Fund has the right to elect early termination of the
Forward Transactions, in whole or in part, at any time in accordance with the
Master Confirmation, and the Counterparty has the right to elect early
termination of the Forward Transactions, in whole or in part, upon prior
written notice to ValueAct Master Fund.

     The Forward Transactions do not give the Reporting Persons direct or
indirect voting, investment or dispositive control over any securities of the
Issuer and do not require the Counterparty to acquire, hold, vote or dispose
of any securities of the Issuer. Accordingly, the Reporting Persons disclaim
any beneficial ownership of any shares of Common Stock that may be referenced
in such contracts and of any shares of Common Stock or other securities or
financial instruments that may be held from time to time by the Counterparty.

-----------------------------------------------------------------------------

     The Reporting Persons may, from time to time, enter into and dispose of
swaps, options or other derivative transactions with one or more
counterparties that are based upon the value of shares of the Common Stock,
which transactions may be significant in amount. The profit, loss and/or
return on such contracts may be wholly or partially dependent on the market
value of the shares of the Common Stock.

     Other than as described in this Report and as previously reported, the
Reporting Persons have no understandings, arrangements, relationships or
contracts relating to the Issuer's Common Stock which are required to be
described hereunder.
