The close of business on April 20, 2021 has been fixed as the record date for the
determination of Stockholders entitled to notice of, and to vote at, the Meeting and any adjournment or postponement thereof. On that date, the Corporation had outstanding 752,740 shares of $2.50 cumulative preferred stock (the Preferred
Stock), each share being entitled to two votes, and 52,116,356.067 shares of common stock, par value $0.50 (the Common Stock), each share being entitled to one vote. For all matters to be voted upon, an abstention or broker
non-vote will not be considered a vote cast. Abstentions and broker non-votes, if any, will be considered present for the purpose of determining the presence of a quorum. For purposes of the vote on the election of each nominee for Director
(Proposal 1), abstentions and broker non-votes, if any, with respect to a Director will have the same effect as a vote against that Director. For purposes of the vote on ratification of the selection of an independent registered public accounting
firm (Proposal 2), abstentions and broker non-votes, if any, will have no effect on the result of the vote.
The presence
virtually or by proxy of Stockholders entitled to cast a majority of all the votes entitled to be cast at the Meeting shall constitute a quorum. In the event that a quorum is not present at the Meeting or, even if a quorum is so present, in the
event that sufficient votes in favor of any Board proposal (including the election of each of the Boards nominees for Director) are not received and tabulated prior to the time the Meeting is called to order, the chairman of the Meeting may
adjourn the Meeting with no notice other than an announcement at the Meeting and further solicitation may be made with respect to such Board proposal. If a vote to adjourn the Meeting with respect to one or more of the Boards proposals is
called, the votes of Stockholders indicating a vote for, or not providing instructions with respect to, a Board proposal in their Proxies will be cast for adjournment with respect to that proposal and votes of Stockholders indicating a vote against
such a Board proposal will be cast against adjournment with respect to that proposal.
