Submitting a proxy over the Internet or by telephone is convenient, saves on postage and mailing costs and is recorded immediately, minimizing risk that postal delays may cause votes to arrive late and therefore not be counted. Stockholders who attend the Express Scripts special meeting may vote in person, and any previously submitted proxies will be superseded by the vote cast at the Express Scripts special meeting. Shares that are held in a brokerage account in the name of the broker are said to be held in ‘‘street name.’’ Stockholders who hold their shares in ‘‘street name’’ will need to obtain a voting instruction card from the institution that holds their shares and must follow the voting instructions given by that institution. Stockholders who hold shares in ‘‘street name’’ and wish to vote at the Express Scripts special meeting must obtain a legal proxy form from the institution that holds their shares and bring that proxy to the Express Scripts special meeting.
