Preferred Stock tendered pursuant to the Exchange Offer may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date or, if not previously returned by the Company, after 40 business days from the commencement of the Exchange Offer if the Company has not accepted the tendered Preferred Stock for exchange by that date.
