Purpose of Transaction.

Item 4 is hereby amended to add the following:

On March 28, 2017, Starboard Value LP and certain of its affiliates (collectively, “Starboard”) entered into a Cooperation and Support Agreement with the Issuer (the “Agreement”) to implement certain changes to the leadership and governance of the Issuer, which include the following: (i) the appointment of three (3) new directors, including Arthur Higgins, the newly appointed President and CEO of the Issuer, Gavin Molinelli, a Partner of Starboard Value LP, and William McKee, former Executive Vice President and Chief Financial Officer of Barr Pharmaceuticals, LLC; and (ii) the appointment of James Fogarty as the new Chairman of the Board. The following description of the Agreement is qualified in its entirety by reference to the Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

Pursuant to the terms of the Agreement, (i) the Board was reconstituted to consist of the following nine (9) directors: Karen Dawes, James Fogarty, Arthur Higgins, Louis Lavigne, William McKee, Gavin Molinelli, Robert Savage, Peter Staple and James Tyree (the “Directors”), with Mr. Fogarty appointed as Chairman of the Board; (ii) the Issuer’s slate of nominees for election as directors at the Issuer’s 2017 Annual Meeting of Shareholders (the “2017 Annual Meeting”) shall consist of the Directors (the “2017 Slate”); (iii) the standing committees of the Board shall be reconstituted as follows: (a) the Nominating and Corporate Governance Committee shall consist of Messrs. Molinelli (Chairman), Lavigne, McKee and Savage; (b) the Compensation Committee shall consist of Messrs. Savage (Chairman), McKee, Molinelli and Staple; and (c) the Audit Committee shall consist of Messrs. Lavigne (Chairman), Staple and Tyree and Ms. Dawes.

Pursuant to the terms of the Agreement, Starboard agreed, among other things, to appear in person or by proxy at the 2017 Annual Meeting and vote all Shares beneficially owned by it (a) in favor of the 2017 Slate, and (b) during the Period, in a manner consistent with the recommendation of the Board, provided, however, that if Mr. Molinelli has voted against any such matter (other than the 2017 Slate) in a vote of the Board, Starboard shall be permitted to vote against the Board’s recommendation with respect to such matter.

Pursuant to the terms of the Agreement, Starboard agreed to certain customary standstill provisions, effective as of the date of the Agreement until 12:01 a.m., Eastern time, on the date that is fifteen (15) business days prior to the deadline for the submission of shareholder nominations for the Issuer’s 2018 Annual Meeting of Shareholders (the “Period”). The standstill provisions generally prohibit Starboard from taking specified actions with respect to the Issuer and its securities, including, among others: (i) soliciting or participating in the solicitation of proxies; (ii) joining any “group” or becoming party to any voting arrangement or agreement; (iii) seeking or encouraging others to submit nominations for election or removal of directors; (iv) making shareholder proposals or offers with respect to mergers, acquisitions and other business combinations; or (v) seeking board representation other than as provided in the Agreement.
