 dividend payment date to, but excluding, the next succeeding dividend payment date, except for the initial dividend period, which will be the 
 period from, and including, the date of issuance of the Series B Preferred Stock to, but excluding, the first dividend payment date.                                                                         |

| If a dividend on the Series B Preferred Stock is declared for any dividend period, such dividend will be calculated on the basis of a 360-day year consisting of twelve 30-day months. In the event that any dividend payment date is not a business day (as defined in “Description of the Series B Preferred Stock — Dividends” beginning on page S-24), then the dividend with respect to that dividend payment date will be paid on the next succeeding business day, without interest or other payment in respect of such delayed payment. For the avoidance of doubt, 
 the succeeding dividend period will be from, and including, the previous dividend payment date (that was not a business day) to, but excluding, the next succeeding dividend period’s dividend payment date.                                                                                                                                                                                                                                                                                                                                                                |

| So long as any Series B Preferred Stock remains outstanding, unless full dividends for the most recently completed dividend 
 period have                                                                                                                 |
