**TABLE OF CONTENTS

The terms of the indenture provide that, in certain circumstances, the obligations of the issuer under the debt securities may be assumed by another entity. Any such assumption might be treated for U.S. federal income tax purposes as a deemed disposition of debt securities by a U.S. holder in exchange for new debt securities issued by the new obligor. As a result of this deemed disposition, a U.S. holder could be required to recognize capital gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the issue price of the new debt securities (as determined for U.S. federal income tax purposes), and the U.S. holder’s tax basis in the debt securities. U.S. holders should consult their tax advisors concerning the U.S. federal income tax consequences to them of a change in obligor with respect to the debt securities.**
