have been declared to be due and payable under Section 8.1, the principal of and premium (if any) and interest on all
Debentures then outstanding, together with any other amounts due hereunder, the Trustee may in its discretion and
shall upon receipt of a request in writing signed by the holders of not less than 25% in principal amount of the
Debentures then outstanding and upon being funded and indemnified to its reasonable satisfaction against all costs,
expenses and liabilities to be incurred, proceed in its own name on behalf of the holders of Debentures and as the

and interest on all the Debentures then outstanding together with any other amounts due hereunder by such
proceedings authorized by this Indenture or by law or equity as the Trustee in such request shall have been directed
to take, or if such request contains no such direction, or if the Trustee shall act without such request, then by such
proceedings authorized by this Indenture or by suit at law or in equity as the Trustee shall deem expedient.
