Upon presentation to the Trustee of any Senior Note Series B Bonds by the Senior Note Trustee for payment, such Senior Note Series B Bonds so presented shall be redeemed and paid in full. In the event the principal of all Senior Notes Due 1999 is declared due and payable or becomes automatically due and payable pursuant to Section 602 of the Senior Note Indenture, upon the filing with the Trustee of a written demand for the acceleration of the payment of principal of all Senior Note Series B Bonds, the payment of principal on all Senior Note Series B Bonds shall become immediately due and payable and the Trustee shall provide to the Senior Note Trustee an irrevocable, valid and unconditional notice of acceleration of all Senior Note Series B Bonds.
