Any such share repurchases will be made by the Company from time to time in the open market at the prevailing open market price using cash on hand, in compliance with the applicable rules and regulations of the New York Stock Exchange and federal and state securities laws and the terms of the Company's senior secured debt. The Company will cancel all of the shares repurchased. The Company expects to continue the share repurchase program indefinitely. The Company will base the timing and amounts of any purchases on market conditions and other factors including price, regulatory requirements and capital availability. The share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares of Class A Stock. Depending on market conditions and other factors, the Company may commence or suspend repurchases from time to time without notice.
