IMPORTANT MERGER VOTE

PLEASE ACT PROMPTLY TO VOTE YOUR SHARES

August 1, 2007

Dear Fellow Stockholder:

     According to our latest records, we have not received your voting instructions for the important special meeting of stockholders of Symbion, Inc. to be held on Wednesday, August 15, 2007. Your vote is extremely important, regardless of the number of common shares of Symbion that you own. Please note that approval of the merger described in the proxy statement dated July 17, 2007, requires the affirmative vote of at least a majority of our outstanding common shares entitled to vote on such matter. Accordingly, if you do not vote, it has the same effect as a vote “against” the proposal.

     Please use one of the following simple methods to promptly provide your voting instructions:

     If the merger is completed, you, as a holder of Symbion common stock, will be entitled to receive $22.35 in cash for each share of Symbion common stock held, as more fully described in the proxy statement. For the reasons set forth in the proxy statement, the Symbion Board of Directors recommends that you vote “FOR” the approval of the merger and all other proposals on the agenda. We respectfully request that you vote your shares at your earliest convenience.

     If you have any questions or need assistance voting your shares, please call D.F. King & Co., Inc. toll free at 1-800-758-5378.

     On behalf of your Board of Directors, thank you for your cooperation and continued support.
