Your failure to vote will have the same effect as a vote against the adoption of the Merger Agreement and the approval of the Merger. Therefore, your vote is very important.
As detailed in the proxy supplement attached to this notice, holders of Caremark common stock will be entitled to appraisal rights in connection with the Merger if they comply with procedures described in more detail in the proxy supplement. Merely voting against the adoption of the Merger Agreement will not preserve the right of Caremark stockholders to appraisal under Delaware law; rather, a stockholder wishing to demand appraisal rights must deliver to Caremark, before the special meeting, a separate written demand for appraisal of such stockholders shares and must hold such shares continuously through the effective time. Also, because a submitted proxy not marked against or abstain will be voted for the proposal to adopt the Merger Agreement, the submission of a proxy not marked against or abstain will result in the waiver of appraisal rights. Caremark stockholders who hold shares in the name of a bank, broker or other nominee must instruct their nominee to take the steps set forth in the proxy supplement to properly demand appraisal for their shares.
The close of business on January 15, 2007 has been fixed as the record date, which is referred to as the Caremark record date, for the determination of Caremark stockholders entitled to notice of, and to vote at, the Caremark special meeting or any adjournments or postponements of the Caremark special meeting. Only holders of record of Caremark common stock at the close of business on the Caremark record date are entitled to notice of, and to vote at, the Caremark special meeting. A complete list of stockholders entitled to vote at the Caremark special meeting will be available for examination by any of Caremarks stockholders at Caremarks headquarters at 211 Commerce Street, Suite 800, Nashville, Tennessee 37201 for purposes pertaining to the Caremark special meeting, during normal business hours, for a period of 10 days before the Caremark special meeting, and at the time and place of the Caremark special meeting.
