The 10b5-1 Plan, which will increase Ms. Hund-Mejean's overall net share holdings, allows for: (i) the exercise of 7,500 shares of Class A common stock underlying stock option awards, with Ms. Hund-Mejean selling sufficient shares to cover the stock option exercise cost as well as taxes due in respect of the vested stock options while she continues to own the underlying shares following the stock option exercise (the "Net Shares"), and (ii) the simultaneous sale of an amount of shares of Class A common stock (associated with restricted stock unit awards) greater than the Net Shares. Accordingly, following these transactions, Ms. Hund-Mejean's overall number of shares of Class A common stock expected to be owned would increase. The 10b5-1 Plan provides for sales of specified share amounts at specified market prices, subject to specified limitations. Sales pursuant to the 10b5-1 Plan are expected to begin as early as May 15, 2012 and will end no later than July 15, 2012. The 10b5-1 Plan may terminate sooner in accordance with its terms.

Ms. Hund-Mejean will continue to be subject to the Company's executive stock ownership guidelines until reaching the age of 62, whereby she is encouraged to hold at least four times her base salary in stock. For purposes of the stock ownership guidelines, shares of Class A Common Stock held directly or indirectly by Ms. Hund-Mejean are included; however, restricted stock units, performance stock units and unexercised stock options held are excluded.
