In connection with the Agreement defined and described in Item 4 below, Messrs. Morphy and Shea are no longer members of the Section 13(d) group and shall cease to be Reporting Persons immediately after the filing of this Amendment No. 4. The remaining Reporting Persons will continue filing as a group statements on Schedule 13D with respect to their beneficial ownership of securities of the Issuer to the extent required by applicable law. Each of the remaining Reporting Persons is party to the Joint Filing Agreement, as further described in Item 6 below.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended to read as follows:

The 1,945 Shares beneficially owned by Mr. Feld, which include Shares of restricted stock that vest within 60 days hereof, were granted to Mr. Feld by the Issuer in his capacity as a director of the Issuer.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On May 18, 2016, Starboard Value LP and certain of its affiliates (collectively, “Starboard”) entered into an agreement with the Issuer (the “Agreement”) regarding the composition of the Issuer’s Board of Directors (the “Board”), which, except as otherwise set forth in the Agreement, supersedes and replaces the initial agreement between Starboard and the Issuer, dated March 21, 2015 (the “Initial Agreement”), pursuant to which Peter A. Feld and Michelle McKenna-Doyle (collectively with Norman R. Sorenson, the “Initial Directors”) were appointed to the Board as Class I directors with terms expiring at the Issuer’s 2017 annual meeting of stockholders (the “2017 Annual Meeting”) and Mr. Sorensen was appointed to the Board as a Class II director with a term expiring at the Issuer’s 2018 annual meeting of stockholders (the “2018 Annual Meeting”). 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, the Issuer agreed, among other things, to: (i) appoint John Morphy as a Class III director (the “First New Independent Director”) with a term expiring at the 2016 annual meeting of stockholders (the “2016 Annual Meeting”) and set the size of the Board at ten (10) members; (ii) commence a search for one (1) new independent director (the “Second New Independent Director” and together with the First New Independent Director, the “New Independent Directors”) to be appointed to the Board as a Class II director with a term expiring at the 2018 Annual Meeting and retain a nationally-recognized director search firm to assist with the Nominating and Corporate Governance Committee’s search for such new independent director; (iii) nominate, recommend, support and solicit proxies for the election of the First New Independent Director to the Board at the 2016 Annual Meeting together with the Issuer’s incumbent Class III directors, Michael W. Brown and Richard G. Rawson (collectively, the “Class III directors”); (iv) accept Carol R. Kaufman’s irrevocable letter pursuant to which Ms. Kaufman has agreed to reduce her term of service as a director on the Board and any applicable committee or subcommittee of the Board, to end at the conclusion of the 2017 Annual Meeting, provided that Ms. Kaufman may revoke her letter under certain circumstances; (v) immediately reconstitute the Nominating and Corporate Governance Committee with the following members: Austin P. Young, Mr. Brown, Mr. Feld and Ms. McKenna-Doyle, with the Chairperson to be Ms. McKenna-Doyle and to fix the size of the Nominating and Corporate Governance Committee at four (4) members during the Standstill Period (defined below); (vi) reconstitute the Compensation Committee with the following members: Mr. Brown, Ms. McKenna-Doyle, Mr. Feld and the Second New Independent Director, with the Chairperson to be Mr. Brown, provided that during the Standstill Period, Mr. Feld shall at all times be a member of the Compensation Committee; (vii) reconstitute the Finance, Risk Management and Audit Committee with the following members: Mr. Morphy, Mr. Sorensen, Mr. Young and Ms. Kaufman, with the Chairperson to be Mr. Young; (viii) ensure that during the Standstill Period, each committee of the Board includes at least one of the Initial Directors and the First New Independent Director, subject to meeting certain criteria; (ix) not increase the size of the Board to more than (10) members or seek to change the classes on which the Board members serve, in each case without the prior written consent of Starboard during the Standstill Period; and (x) hold the 2016 Annual Meeting no later than July 8, 2016.

The Agreement also provides that if any of the Initial Directors (or any replacement director) is unable to serve as a director, resigns or is removed as a director prior to the 2017 Annual Meeting, with respect to Mr. Feld and Ms. McKenna-Doyle (or their replacement directors), or the 2018 Annual Meeting, with respect to Mr. Sorenson (or his replacement director) and at such time Starboard beneficially owns in the aggregate at least the lesser of (i) three percent (3.0%) of the Issuer’s then outstanding Shares and (ii) 641,581 Shares (the “Minimum Ownership Threshold”), then Starboard has the ability to recommend a substitute person, who meets certain independence and experience criteria. In addition, the Agreement provides that if any of the New Independent Directors (or any replacement director) is unable to serve as a director, resigns or is removed as a director prior to the 2019 annual meeting of stockholders, with respect to the First New Independent Director, or the 2018 Annual Meeting, with respect to the Second New Independent Director and at such time Starboard meets the Minimum Ownership Threshold, then a replacement director will be appointed in accordance with the same procedures set forth in the Agreement with respect to the appointment of the Second New Independent Director.

Pursuant to the terms of the Agreement, Starboard agreed, among other things: (i) to withdraw its notice of stockholder nomination of individuals for election as directors at the 2016 Annual Meeting submitted to the Issuer on March 12, 2016; (ii) not to nominate any person for election at the 2016 Annual Meeting; (iii) not to submit any proposal for consideration at, or bring any other business before, the 2016 Annual Meeting; (iv) not to initiate, encourage or participate in any “withhold” or similar campaign with respect to the 2016 Annual Meeting; and (v) to appear in person or by proxy at the 2016 Annual Meeting and vote all Shares beneficially owned by it (a) in favor of the election of the Class III Directors, (b) in favor of the ratification of the appointment of Ernst & Young LLP as the Issuer’s independent registered public accounting firm for the fiscal year ending December 31, 2016, and (c) in accordance with the Board’s recommendation with respect to the Issuer’s “say-on-pay” proposal. In addition, Starboard agreed that Mr. Feld’s irrevocable resignation letter submitted in accordance with the terms of the Initial Agreement shall remain in full force and effect, pursuant to which Mr. Feld shall resign from the Board and all applicable committees and subcommittees thereof if at any time Starboard’s aggregate beneficial ownership of the Issuer’s Shares decreases to less than the Minimum Ownership Threshold.

Starboard also agreed to certain customary standstill provisions, effective as of the date of the Agreement through the earlier of (i) fifteen (15) business days prior to the deadline for the submission of stockholder nominations for the 2017 Annual Meeting or (ii) one hundred (100) days prior to the anniversary date of the 2016 Annual Meeting (the “Standstill 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 stockholder proposals or offers with respect to mergers, acquisitions and other business combinations; or (v) seeking board representation other than as provided in the Agreement.
