( 1 )These shares of the Issuer's Class A Common Stock (each, a "Class A Share") were acquired by the Reporting Person upon the conversion of an equal number of shares of the Issuer's Class B Common Stock (each, a "Class B Share") that had been beneficially owned by the Reporting Person. ( 2 )This transaction was executed in multiple trades with sales prices ranging from $225.030 to $226.029. The price reported above reflects the weighted average sales price for the cumulative trades. The Reporting Person hereby undertakes to provide upon request to the SEC staff, the Issuer or a security holder of the Issuer information regarding the individual trades. ( 3 )This transaction was executed in multiple trades with sales prices ranging from $226.310 to $227.309.

The Reporting Person hereby undertakes to provide upon request to the SEC staff, the Issuer or a security holder of the Issuer information regarding the individual trades. ( 4 )This transaction was executed in multiple trades with sales prices ranging from $227.320 to $228.319.

In addition, each Class B Share will convert automatically into one Class A Share upon any transfer, except for any transfers (i) by a partnership or limited liability company that was a registered holder of Class B Shares to anyone who was a partner or member of any such partnership or limited liability company at the effective time, and (ii) to a "qualified recipient," as defined in the Issuer's amended and restated certificate of incorporation. The Class B Shares have no expiration date. ( 7 )All of the outstanding Class B Shares will convert automatically into Class A Shares, on a one share for one share basis, on the date when the number of the outstanding Class B Shares represent less than 10% of the sum of the outstanding Class A Shares and Class B Shares. ( 8 )The reported securities, which were previously reported as indirectly owned by the Reporting Person through his spouse, were transferred to, and are now held directly by the Reporting Person.
