As provided in the Issuer’s Amended and Restated Certificate of Incorporation, each share of Class B Common Stock is convertible at any time, at the option of the holder, into one share of Class A Common Stock.	
The Reporting Person is party to certain agreements with the Separately Filing Group Members (as defined in the Schedule 13D), which agreements contain, among other things, certain voting agreements and limitations on the sale of their shares of Common Stock. As a result, the Reporting Person may be deemed to be a member of a “group,” within the meaning of Section 13(d)(3) of the Act (as defined in the Schedule 13D), comprised of the Reporting Person and the Separately Filing Group Members. Shares listed as beneficially owned by the Reporting Person exclude shares held by any other Reporting Person or by any of the Separately Filing Group Members, in each case as to which the Reporting Person disclaims beneficial ownership.
All references to the number of shares outstanding are as of May 30, 2013, as reported in the Issuer’s Current Report on Form 8-K, filed on May 30, 2013. The percentage is calculated using the total number of shares of Common Stock beneficially owned by the Reporting Person and based on 159,551,851 shares of Common Stock outstanding as of May 30, 2013. With respect to matters upon which the Issuer’s stockholders are entitled to vote, the holders of Class A Common Stock and Class B Common Stock vote together as a single class, and each holder of Class A Common Stock is entitled to one vote per share and each holder of Class B Common Stock is entitled to ten votes per share. The shares of Class B Common Stock owned by the Reporting Person represent 5.9% of the total voting power of the Common Stock as of May 30, 2013. The percentage of total voting power of the Common Stock is calculated based on the total voting power of the Common Stock outstanding as of May 30, 2013, which is comprised of 45,910,600 shares of Class A Common Stock and 113,641,251 shares of Class B Common Stock and assumes that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.

As provided in the Issuer’s Amended and Restated Certificate of Incorporation, each share of Class B Common Stock is convertible at any time, at the option of the holder, into one share of Class A Common Stock.	
The Reporting Person is party to certain agreements with the Separately Filing Group Members (as defined in the Schedule 13D), which agreements contain, among other things, certain voting agreements and limitations on the sale of their shares of Common Stock. As a result, the Reporting Person may be deemed to be a member of a “group,” within the meaning of Section 13(d)(3) of the Act (as defined in the Schedule 13D), comprised of the Reporting Person and the Separately Filing Group Members.

All references to the number of shares outstanding are as of May 30, 2013, as reported in the Issuer’s Current Report on Form 8-K, filed on May 30, 2013. The percentage is calculated using the total number of shares of Common Stock beneficially owned by the Reporting Person and based on 159,551,851 shares of Common Stock outstanding as of May 30, 2013.

The shares of Class B Common Stock owned by the Reporting Person represent less than 0.1% of the total voting power of the Common Stock as of May 30, 2013.

Each SAR gives the holder the right to receive a number of shares of Class A Common Stock equal to the excess of the value of one share of Class A Common Stock at the exercise date, over the exercise price. The number of shares of Class A Common Stock that Mr. Pritzker will receive upon exercise of such SARs is not determinable until the date of exercise and therefore is not included in the information above.

Form 8-K, filed May 30, 2013.	
2  	The information shown in the table with respect to the percentage of Class A Common Stock beneficially owned is based on 45,910,600 shares of the Class A Common Stock outstanding as of May 30, 2013, assuming that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.	
3  	The information shown in the table with respect of the percentage of Class B Common Stock beneficially owned is based on 113,641,251 shares of Class B Common Stock outstanding as of May 30, 2013.	
4  	The information shown in the table with respect to the percentage of total Common Stock beneficially owned is based on 45,910,600 shares of Class A Common Stock and 113,641,251 shares of Class B Common Stock outstanding as of May 30, 2013.

The percentage of total voting power of the shares of Common Stock is calculated based on the total voting power of the shares of Common Stock outstanding as of May 30, 2013, which is comprised of 45,910,600 shares of Class A Common Stock and 113,641,251 shares of Class B Common Stock and assumes that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.

Each SAR gives the holder the right to receive a number of shares of Class A Common Stock equal to the excess of the value of one share of Class A Common Stock at the exercise date, over the exercise price. The number of shares of Class A Common Stock that Mr. Pritzker will receive upon exercise of such SARs is not determinable until the date of exercise and therefore is not included in the information above.
