NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound hereby, agree as follows:

1.                                       Board Appointments and Related Agreements .

(a)                                  Board Appointments .

(i)                                      The Company agrees that immediately following the execution of this Agreement, the Board and all applicable committees of the Board shall take all necessary actions to appoint Marran H. Ogilvie, George W. Wurtz III, and Robert H. Yanker (each an “ Appointed Director ” and, collectively, the “ Appointed Directors ”) and Guillermo Novo (the “ Additional Independent Director ” and, collectively with the Appointed Directors, the “ New Directors ”) as directors of the Company.  Prior to the date of this Agreement, each of the New

Directors has submitted to the Company a fully completed copy of the Company’s standard director & officer questionnaire (the “ D&O Questionnaire” ).

(ii)                                   The Company agrees that (A) the Board shall nominate the following individuals, and only the following individuals, for election to the Board at the 2018 Annual Meeting for terms expiring at the Company’s 2019 annual meeting of shareholders (the “ 2019 Annual Meeting ”) and subject to their consent to serve:  (x) each Appointed Director (including any Replacement Director); (y) the Additional Independent Director; and (z) William F. Austen, Katherine C. Doyle, Adele M. Gulfo, David S. Haffner, Timothy M. Manganello, Arun Nayar, David T. Szczupak, Holly A. Van Deursen, and Philip G. Weaver (collectively, the “ Continuing Directors ”), and (B) the Company shall recommend, support and solicit proxies for the Appointed Directors at the 2018 Annual Meeting in the same manner as it recommends, supports, and solicits proxies for the election of the Continuing Directors and the Additional Independent Director.  The Company shall use its reasonable best efforts to hold the 2018 Annual Meeting no later than May 31, 2018.

(iii)                                If any Appointed Director (or any Replacement Director, as defined below) is unable or unwilling to serve as a director and ceases to be a director, resigns as a director or is removed as a director prior to the expiration of the Standstill Period (as defined below), and at such time Starboard beneficially owns (as determined under Rule 13d-3 promulgated under the Exchange Act) in the aggregate at least the lesser of 1.5% of the Company’s then-outstanding Common Stock (on an as-converted basis, if applicable) and 1,364,633 shares of Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments) (such lesser amount, the “ Minimum Ownership Threshold ”), Starboard shall have the ability to recommend a substitute person in accordance with this Section 1(a)(iii)  (any such replacement nominee shall be referred to as a “ Replacement Director ”).  Any Replacement Director must (A) be reasonably acceptable to the Board (such acceptance not to be unreasonably withheld), (B) qualify as “independent” pursuant to New York Stock Exchange (“ NYSE ”) listing standards, (C) have the relevant financial and business experience to be a director of the Company and (D) be independent of Starboard (for the avoidance of doubt, the nomination by Starboard of such person to serve on the board of any other company shall not, in and of itself, cause such person to not be deemed independent of Starboard).  The Nominating and Corporate Governance Committee of the Board (the “ Nominating Committee ”) shall make its determination and recommendation regarding whether such Replacement Director meets the foregoing criteria within five (5) business days after (1) such nominee has submitted to the Company the D&O Questionnaire and (2) representatives of the Board have conducted customary interviews of such nominee.  The Company shall use its reasonable best efforts to conduct any interviews contemplated by this Section 1(a)(iii)  as promptly as practicable, but in any case, assuming reasonable availability of the nominee, within ten (10) business days after Starboard’s submission of such nominee.  In the event the Nominating Committee does not accept a person recommended by Starboard as a

2

Replacement Director, Starboard shall have the right to recommend additional substitute persons whose appointment shall be subject to the Nominating Committee recommending such persons in accordance with the procedures described above.  Upon the recommendation of a Replacement Director nominee by the Nominating Committee, the Board shall vote on the appointment of such Replacement Director to the Board no later than five (5) business days after the Nominating Committee’s recommendation of such Replacement Director; provided , however , that if the Board does not appoint such Replacement Director to the Board pursuant to this Section 1(a)(iii) , the Parties shall continue to follow the procedures of this Section 1(a)(iii)  until a Replacement Director is elected to the Board.  Subject to NYSE rules and applicable law, upon a Replacement Director’s appointment to the Board, the Board and all applicable committees of the Board shall take all necessary actions to appoint such Replacement Director to any applicable committee of the Board of which the replaced director was a member immediately prior to such director’s resignation or removal. Subject to NYSE rules and applicable law, until such time as any Replacement Director is appointed to any applicable committee of the Board, one of the other Appointed Directors (as designated by Starboard) will serve as an interim member of such applicable committee. Any Replacement Director designated pursuant to this Section 1(a)(iii)  replacing an Appointed Director prior to the 2018 Annual Meeting shall stand for election at the 2018 Annual Meeting together with the Company’s other nominees.  Starboard shall promptly (and in any event within five business days) inform the Company in writing if Starboard fails to satisfy the Minimum Ownership Threshold at any time.

(iv)                               During the period commencing with the 2018 Annual Meeting through the expiration of the Standstill Period, the Board shall take all necessary actions to set the size of the Board at no more than 13 directors, unless Starboard consents in writing to any proposal to increase the size of the Board.

(b)                                  Board Committees .

(i)                                      Immediately following the execution of this Agreement, the Board and all applicable committees of the Board shall take all necessary actions to appoint David S. Haffner, Marran H. Ogilvie, Philip G. Weaver, and Robert H. Yanker to the Finance and Strategy Committee of the Board (the “ Finance and Strategy Committee ”) and to appoint Philip G. Weaver as its Chairman.  During the Standstill Period, unless otherwise agreed by the Finance and Strategy Committee, the Finance and Strategy Committee shall be composed of four directors, including two Appointed Directors (or Replacement Directors).  Subject to NYSE rules and applicable law, until such time as a Replacement Director is appointed to the Finance and Strategy Committee, one of the other Appointed Directors (as designated by Starboard) will serve as an interim member of the Finance and Strategy Committee.

3

(ii)                                   The Company agrees that the Board shall not amend the Finance and Strategy Committee charter during the Standstill Period without Starboard’s prior written consent.

(iii)                                Subject to NYSE rules and applicable laws, during the Standstill Period, the Board and all applicable committees of the Board shall give each of the New Directors the same due consideration for membership to each other committee of the Board as any other independent director.

(iv)                               Subject to NYSE rules and applicable laws, during the Standstill Period, the Board and all applicable committees of the Board shall take all action necessary to ensure that each committee of the Board formed after the date of this Agreement and during the Standstill Period includes at least one Appointed Director.

(c)                                   Additional Agreements.
