An issuable PIK Class A-2 Common Share shall not be issued and paid to any holder who is not also the holder of the underlying share of Class A-2 Common Stock in respect of which such PIK Class A-2 Common Share became accrued and issuable. The holder of a share of Class A-2 Common Stock that is to be permissibly transferred must notify the Secretary of the Corporation and any transfer agent for the Class A-2 Common Stock, according to instructions provided by the Corporation or any such transfer agent, of such proposed sale, transfer or other disposition at least three (3) business days in advance of the effective date of such permitted sale, transfer or other disposition.

(F)                                  Conversion . Upon the Conversion End Date, any PIK Class A-2 Common Shares that remain issuable but unpaid as of such date shall be issued and paid, prior to the Conversion. Immediately thereafter, each share of Class A-2 Common Stock shall automatically be converted into the right to receive one (1) fully paid and non-assessable share of Class A Common Stock (including fractional shares) (the “ Conversion ”). The “ Conversion End Date ” shall mean the earlier to occur of (1) the end of the Maximum Accrual Period and (2) the date on

The issuance of shares of Class A Common Stock to holders of shares of Class A-2 Common Stock pursuant to Section 4.4(F) shall be conditioned on delivery by such holders to the Corporation or any transfer agent or exchange agent designated by the Corporation of any transmittal form or transfer instruction and supplemental material as may be required by the Corporation or such designated transfer agent or exchange agent. Such transmittal form or transfer instruction shall state the number of shares of Class A-2 Common Stock held by such holder; provided , that the Corporation shall certify the number of shares of Class A-2 Common Stock held by such holder to facilitate such Conversion. Thereupon, the Corporation shall (1) promptly issue and deliver, or cause its designated transfer agent or exchange agent to issue and deliver, to such holder the number of whole shares of Class A Common Stock to which such holder is entitled, in book-entry form (or, at the election of the holder, in certificated form) and (2) pay to such holder in cash (based on the Class A Common Stock’s fair market value determined by the Board as of the date of Conversion) the value of any fractional share of Class A Common Stock that would be otherwise issuable to such holder. Such Conversion shall be deemed to have been made at the close of business on the Conversion End Date, and the person entitled to receive the shares of Class A Common Stock issuable upon such Conversion shall be treated for all purposes as the record holder of such shares of Class A Common Stock on such date.

(H)                               Notice . Subject to Section 4.4(J), the Corporation shall make available to each holder of Class A-2 Common Stock information regarding the occurrence of any (1) Special Dividend Accrual Event (for the first day on which the Special Dividends accrue and for the day on which such Special Dividends cease), (2) Special Dividend Satisfaction Date, and (3) Conversion End Date, in each case within three (3) business days following such occurrences.
