Atrion Corporation (the "Registrant") and Emile A Battat, the Registrant's Chairman, entered into a Third Amendment to Amended and Restated Employment Agreement, dated as of March 17, 2018 (the “Third Amendment”).  The Third Amendment (1) provides that Mr. Battat will receive the same benefits upon retirement as he would receive if his employment were terminated without just cause or with good reason, or due to death or disability; (2) changes the advance notice of nonrenewal from 30 days to six months; and (3) eliminates the obligation for the Registrant to pay to Mr. Battat a gross-up payment in the event the payments or benefits provided to him are subject to an excise tax under Section 4999 (Golden parachute payments) of the Internal Revenue Code of 1986, as amended.  

The foregoing summary of the Third Amendment is qualified in its entirety by the Third Amendment, which is attached to this Current Report on Form 8-K as Exhibit 10.1 and incorporated herein by this reference.

On March 13, 2018, the Board of Directors of the Registrant amended the Registrant’s Bylaws to change the voting standard for the election of directors from a plurality to a majority voting standard in uncontested elections. Section 1.09 of the Bylaws has been amended to provide that each director will be elected in an uncontested election by the vote of the majority of the votes cast with respect to that director’s election at a meeting of stockholders. Section 1.09 of the Bylaws has also been amended to set forth a director resignation procedure that will apply if a nominee for reelection as director in an uncontested election fails to receive a majority of the votes cast with respect to that director’s reelection. Section 2.10 of the Bylaws has been amended to state in greater detail the information that is to be provided by a stockholder who intends to nominate a person for election as director respecting the proposed nominee. The changes to the Bylaws also include certain non-substantive revisions.

The foregoing summary is qualified in its entirety by reference to the full text of the Bylaws, as amended, a copy of which is attached to this Current Report on Form 8-K as Exhibit 3.1 and incorporated herein by this reference.
