In that offering, the underwriters also have the option to purchase an additional 675,000 shares of Class A common stock from those selling shareholders to cover over-allotments.

UNDERWRITING

        The selling shareholders are offering their shares of our Class A common stock through Merrill Lynch, Pierce, Fenner & Smith Incorporated, as underwriter. Subject to the terms and conditions described in a purchase agreement among us, the selling shareholders and the underwriter, the selling shareholders have agreed to sell to the underwriter, and the underwriter has agreed to purchase from the selling shareholders, 243,786 shares of Class A common stock.

        The underwriter has agreed to purchase all of the shares sold under the purchase agreement if any of these shares are purchased.

        We and the selling shareholders have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriter may be required to make in respect of those liabilities.

        The underwriter is offering the shares, subject to prior sale, when, as and if issued to and accepted by it, subject to approval of legal matters by its counsel, including the validity of the shares, and other conditions contained in the purchase agreement, such as the receipt by the underwriter of officer's certificates and legal opinions.

Price Stabilization and Short Positions

        Until the distribution of the shares is completed, Securities and Exchange Commission rules may limit the ability of the underwriter and selling group members from bidding for and purchasing our Class A common stock. However, the underwriter may engage in transactions that stabilize the price of our Class A common stock, such as bids or purchases to peg, fix or maintain that price.

        If the underwriter creates a short position in the Class A common stock in connection with the offering, i.e., if it sells more shares than are listed on the cover of this prospectus supplement, the underwriter may also elect to reduce any short position by purchasing shares in the open market. Purchases of the Class A common stock to stabilize its price or to reduce a short position may cause the price of the Class A common stock to be higher than it might be in the absence of such purchases.

        Neither we nor the underwriter makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our Class A common stock. In addition, neither we nor the underwriter makes any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.
