The WAM Designees shall be selected by mutual agreement of the Company and WAM (such agreement between the parties prior to the end of the Socialization Period as contemplated by this Section 3(a), the " Mutual Agreement "); provided , however , that if the parties are unable to mutually agree on two of the three Candidates to serve as the WAM Designees within the Socialization Period, then (1) WAM shall have the right to submit within  ten (10) days of the end of the Socialization Period timely nominations of director candidates to be nominated for election to the Board at the 2018 annual meeting of stockholders of the Company (the " 2018 Annual Meeting "), (2) the Board shall accept any such nominations by WAM as timely and valid with no objection and (3) this Agreement, except for the nomination right granted in this Section 3(a) and the provisions set forth in Sections 8 and 17, shall terminate automatically without any further action by either of the parties hereto (the " Post-Socialization Period Termination ").  The Company further agrees that it shall not file any proxy statement or make any announcement in connection with the 2018 Annual Meeting prior to the end of the Socialization Period.

(c)

Each of the WAM Designees shall qualify as directors that are "independent" under the applicable independence rules of the Nasdaq Global Market (" Nasdaq "). WAM acknowledges that as a condition to the appointment and nomination of the WAM Designees, such WAM Designees shall have agreed to provide the information that is required to be or is customarily disclosed for candidates for directors and directors in a proxy statement and similar documents under the securities laws applicable to the Company and/or the rules and regulations of Nasdaq.

(d)

Concurrent with the Board's appointment of the WAM Designees to the Board, the Board shall take all necessary actions to immediately appoint at least one (1) WAM Designee (or Replacement Director, as applicable) to serve on each of the Audit Committee, the Nominating and Corporate Governance Committee (the " Nominating Committee ") and the Compensation Committee of the Board.

(e)

If a WAM Designee (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, WAM will designate substitute person(s) for appointment or election to the Board subject to review and approval by the Nominating Committee, with such approval not to be unreasonably withheld (any such replacement nominee, when appointed to the Board, shall be referred to as a " Replacement Director ").  Subject to Nasdaq 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.
