Shares: (i) debt securities, which may be in one or more series (the "Debt

been filed as an exhibit to the Registration Statement (the "Indenture"), which
Indenture is proposed to be entered into between the Company and a trustee to be

into and perform all obligations thereunder and have also assumed the due
authorization by all requisite action, corporate or other, and execution,
countersignature (if necessary) and delivery by such parties of such documents
and that such documents constitute or will constitute valid and binding
obligations of such parties enforceable against such parties in accordance with
