reorganization or other similar laws affecting creditors' rights or debtors'

authorized by the respective Relevant Subsidiary and when executed,
authenticated and delivered in accordance with the terms of the Indenture and

binding obligation of each Relevant Subsidiary, enforceable against each
Relevant Subsidiary in accordance with its terms, subject to applicable
bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization or
other similar laws affecting creditors' rights or debtors' obligations and to
general principles of equity.
