The Amendments became effective on April 22, 2016.

Elimination of References to Rule 14a-11

The Amendments delete Article I, Section 7(e) of the Regulations in its entirety and amend Article I, Section 7(k) to remove all references to Rule 14a-11 of the Exchange Act, which was vacated by the U.S. Court of Appeals for the D.C. Circuit.

The Amendments also amend Article II, Section 1 of the Regulations to fix the number of Directors of the Company at 13 until the annual meeting of shareholders taking place on August 17, 2016 and thereafter fix such number of Directors at 12.

Elimination of Board Classification Provisions

The Amendments further amend Article II, Section 1 of the Regulations to eliminate all remaining board classification provisions.
