Item 4. Purpose of Transaction.

Item 4 is hereby amended
to add the following:

Starboard Value LP (together
with its affiliates, “Starboard”) continues to believe that the Issuer is a great company with a market leading technology
portfolio and product set, but that substantial change is needed given the prolonged underperformance of the Issuer and the growing
disparity between the Issuer’s margins, growth, and stock price performance compared to its peer group. While Starboard hopes
to continue the constructive dialogue it has had with the Issuer’s management team and Board regarding opportunities to unlock
value at the Issuer, including changes to Board composition, in light of the upcoming deadline for shareholder nominations, as
set by the Issuer, and in order to preserve its right as a shareholder, on January 17, 2018, Starboard V&O Fund delivered a
letter to the Issuer (the “Nomination Letter”) nominating a slate of nine highly qualified director candidates, Mary
B. Cranston, Peter A. Feld, Jonathan Khazam, Thomas Lacey, Efrat Makov, Jon A. Olson, Jeffrey C. Smith, Jorge L. Titinger and Gregory
Waters (collectively, the “Nominees”), for election to the Board at the Issuer’s 2018 annual general meeting
of shareholders (the “Annual Meeting”). Starboard carefully selected this highly qualified slate of Nominees who, as
evidenced by their biographies below, collectively bring decades of experience as CEOs, CFOs, COOs, senior executives, and directors
of well-performing technology companies in the United States, Israel, and around the world. Starboard has indicated that it is
still in the process of evaluating the degree of change that it believes is necessary on the Board, and that to the extent it seeks
the election of all nine directors, its present intention would be to expand the size of the Board and add back up to two incumbent
directors, should they be willing to serve, in order to ensure a degree of continuity, as well as to provide additional local market
presence and expertise.

Also, on January 17, 2018,
Starboard issued an open letter to the shareholders of the Issuer, a copy of which is attached hereto as Exhibit 99.1 and is incorporated
herein by reference.
