The prospectus supplement relating to a class series of preferred stock that is subject to mandatory redemption will specify the number of shares of the preferred stock that will be redeemed by us in each year commencing after a date to be specified, at a redemption price per share to be specified, together with an amount equal to all accumulated and unpaid dividends thereon, which will not, if the preferred stock does not have a cumulative dividend, include an accumulation in respect of unpaid dividends for prior dividends periods, to the date of redemption. The redemption price may be payable in cash or other property, as specified in the applicable prospectus supplement. If the redemption price for preferred stock of any series is payable only from the net proceeds of the issuance of our stock, the terms of the preferred stock may provide that, if no stock will have been issued or to the extent the net proceeds from any issuance are insufficient to pay in full the aggregate redemption price then due, the preferred stock will automatically and mandatorily be converted into shares of our applicable stock pursuant to conversion provisions specified in the applicable prospectus supplement.

 preferred stock of the class or series are simultaneously redeemed, and                                          |
