Absent a compelling reason to do otherwise, the Board shall accept the resignation.

The amendments to the Bylaws are effective September 22, 2016. The text of Article II, Section 11 of the Bylaws, as amended, is attached hereto as Exhibit 3.1 and incorporated herein by reference. This description of the amendments is qualified in its entirety by reference to the text thereof.
