Upon the occurrence of a Change of Control, investors will have the right (unless, prior to the Change of Control Conversion Date, the Issuer has provided or provides notice of its election to redeem the Series D Preferred Shares) to convert some or all of the Series D Preferred Shares held by such investor on the Change of Control Conversion Date (the “Change of Control Conversion Right”) into a number of the Issuer’s shares of common stock, par value $0.01 per share, per Series D Preferred Share to be converted equal to the lesser of:

•      the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference plus the amount of any accrued and unpaid dividends to, but not including, the Change of Control Conversion Date (unless the Change of Control Conversion Date is after a record date for a Series D Preferred Share dividend payment and prior to the corresponding Series D Preferred Share dividend payment date, in which case no additional amount for such accrued and unpaid dividend will be included in this sum) by (ii) the Common Share Price; and

•      4.9068, or the Share Cap, subject to certain adjustments;

subject, in each case, to provisions for the receipt of alternative consideration, as described in the prospectus supplement.

If the Issuer has provided or provides a redemption notice, whether pursuant to the Issuer’s special optional redemption right in connection with a Change of Control or the Issuer’s optional redemption right, investors will not have any right to convert the Series D Preferred

Shares in connection with the Change of Control Conversion Right and any Series D Preferred Shares subsequently selected for redemption that have been tendered for conversion will be redeemed on the related date of redemption instead of converted on the Change of Control Conversion Date.

A “Change of Control” is when, after the original issuance of the Series D Preferred Shares, the following have occurred and are continuing:

•     the acquisition by any person, including any syndicate or group deemed to be a “person” under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of shares of the Issuer entitling that person to exercise more than 50% of the total voting power of all shares of the Issuer entitled to vote generally in elections of directors (except that such person will be deemed to have beneficial ownership of all securities that such person has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition); and

•     following the closing of any transaction referred to in the bullet above, neither the Issuer nor the acquiring or surviving entity has a class of common securities (or American Depositary Receipts representing such securities) listed on the New York Stock Exchange, the NYSE Amex Equities or the NASDAQ Stock Market or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE Amex or NASDAQ.

The “Change of Control Conversion Date” will be a business day that is no less than 20 days nor more than 35 days after the date on which the Issuer provides the required notice of the occurrence of a Change of Control to the holders of Series D Preferred Shares.

The “Common Share Price” will be: (i) if the consideration to be received in the Change of Control by holders of the Issuer’s shares of common stock is solely cash, the amount of cash consideration per share of common stock, and (ii) if the consideration to be received in the Change of Control by holders of shares of common stock is other than solely cash, the average of the closing price per share of common stock on the 10 consecutive trading days immediately preceding, but not including, the effective date of the Change of Control.
