Exhibit 3.2.1

Bylaw Amendment Adopted Effective August 8, 2016

(g)    Voting; Proxies. Except as otherwise expressly required by law or provided in the Certificate of Incorporation, each share of capital stock of the Corporation shall entitle the holder thereof to one vote. Except as provided in the next paragraph of this Section 6(g) with respect to the election of directors, any action shall be authorized by a majority of the votes cast except where the Delaware General Corporation Law prescribes a different percentage of votes and/or a different exercise of voting power, and except as may be otherwise prescribed by the provisions of the Certificate of Incorporation and these Bylaws. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by delivering to the Secretary of the Corporation a revocation of the proxy or a new proxy bearing a later date. In the election of directors, and for any other action, voting need not be by ballot.

Except as otherwise provided by these Bylaws, each director shall be elected by the vote of the majority of the votes cast with respect to that director’s election at any meeting for the election of directors at which a quorum is present, provided that if, as of the tenth (10th) day preceding the date the Corporation first mails its notice of meeting for such meeting to the stockholders of the Corporation, the number of nominees exceeds the number of directors to be elected (a “Contested Election”), the directors shall be elected by the vote of a plurality of the votes cast. For purposes of this paragraph, a majority of votes cast shall mean that the number of votes cast “for” a director’s election exceeds the number of votes cast “against” that director’s election (with “abstentions” and “broker nonvotes” not counted as a vote cast either “for” or “against” that director’s election). In order for any incumbent director to become a nominee of the Board of Directors for further service on the Board of Directors, such person must submit an irrevocable resignation, contingent on (i) that person not receiving a majority of the votes cast in an election that is not a Contested Election, and (ii) acceptance of that resignation by the Board of Directors in accordance with the policies and procedures adopted by the Board of Directors for such purpose. In the event an incumbent director fails to receive a majority of the votes cast in an election that is not a Contested Election, the Governance Committee, or such other committee designated by the Board of Directors pursuant to these Bylaws, shall make a recommendation to the Board of Directors as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken. The Board of Directors shall act on the resignation, taking into account the committee’s recommendation, and publicly disclose (by a press release and filing an appropriate disclosure with the Securities and Exchange Commission) its decision regarding the resignation and, if such resignation is rejected, the rationale behind the decision within ninety (90) days following certification of the election results. The committee in making its recommendation and the Board of Directors in making its decision each may consider any factors and other information that they consider appropriate and relevant. Any nominee who tenders his or her resignation pursuant to this Section 6(g) will not participate in the deliberations of the committee or the Board of Directors regarding whether to accept the resignation.
