| • |     | preferred stockholders’ rights relative to common stockholders, such as the right of preferred stockholders                                    
 to receive dividends and amounts on our liquidation, dissolution or winding-up before any such amounts may be paid to our common shareholders; |

Preferred Stockholders’ Rights Rank Shares of each series of preferred stock will rank senior to our common stock with respect to dividends and distributions of assets. However, we will generally be able to pay dividends and distributions of assets to holders of our preferred stock only if we have satisfied our obligations on our indebtedness then due and payable. Dividends Holders of each series of preferred stock will be entitled to receive cash dividends when, as and if declared by our board of directors, from funds legally available for the payment of dividends. The rates and dates of payment of dividends for each series of preferred stock will be stated in your prospectus supplement. Dividends will be payable to holders of record of preferred stock as they appear on our books on the record dates fixed by our board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative, as set forth in the prospectus supplement. 29

Redemption If specified in your prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or the holder’s, and may be redeemed mandatorily. Any restriction on the repurchase or redemption by us of our preferred stock while there is an arrearage in the payment of dividends will be described in your prospectus supplement. Any partial redemptions of preferred stock will be made in a way that our board of directors decides is equitable. Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of these shares, including voting rights, will terminate except for the right to receive the redemption price
