The remaining shares from the option exercise were held.
(2)	The reported price in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $108.205 to $108.545 per share. Mr. Vitale undertakes to provide to the issuer, any security holder of the issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote.
