Change of Control:

A “Change of Control” is when, after the original issuance of the Series C 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, or the Exchange Act, 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 our capital stock entitling that person to exercise more than 50% of the total voting power of all shares of our capital stock 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 point above, neither we nor the acquiring or surviving entity has a class of common securities (or ADRs representing such common securities) listed on the NYSE, the NYSE Amex or NASDAQ, or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE Amex or NASDAQ.

Conversion Rights:

Upon the occurrence of a Change of Control (as defined above), you will have the right (unless we have elected to exercise our special optional redemption right to redeem your Series C Preferred Stock) to convert some or all of your Series C Preferred Stock into a number of shares of our common stock, par value $0.01 per share, equal to the lesser of (A) the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference plus the amount of any accrued and unpaid dividends (whether or not declared) 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 C Preferred Stock dividend payment and prior to the corresponding Series C Preferred Stock 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 Stock Price; and (B) 1.9231 (i.e., the Share Cap), subject, in each case, to certain adjustments and provisions for the receipt of alternative consideration of equivalent value as described in the prospectus supplement.

If we have provided a redemption notice with respect to some or all of the Series C Preferred Stock, holders of any Series C Preferred Stock that we have called for redemption will not be permitted to exercise their Change of Control Conversion Right in respect of any of their shares of Series C Preferred Stock that have been called for redemption, and any Series C Preferred Stock subsequently called for redemption that has been tendered for conversion will be redeemed on the applicable date of redemption instead of converted on the Change of Control Conversion Date.
