How Proxy Votes Are Tabulated

Only the shares of Common Stock represented by valid proxies that have been received and which have not been revoked prior to the time that polls are closed for voting during the meeting will be voted and tallied by the Inspector of Election at the meeting. Votes cast at the meeting by proxy or electronically by attending shareholders will be tabulated by the Inspector of Election. The Inspector of Election will treat shares of Common Stock represented by a valid proxy as present at the meeting for purposes of determining a quorum, whether or not the proxy is marked as casting a vote or abstaining on any or all matters.
