Section 5.2 Waiver of Notice and Demand. The Guarantor hereby waives notice of acceptance of this Preferred Securities Guarantee and of any liability to which it applies or may apply, presentment, demand for payment, any right or remedy to require a proceeding first against the Issuer or any other Person before proceeding directly against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice of redemption and all other notices and demands.
