(1) in the payment of the principal of or any premium or interest on any Security of such series,
(2) arising from the failure to redeem or purchase any Security when required under this Indenture; or
(3) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder
of each Outstanding Security of such series affected.
Upon any such waiver with respect to any series, such default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured, with respect to such series for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent
thereon. A waiver of any past default and its consequences given by or on behalf of any Holder of Securities in connection with a purchase of, or tender or exchange offer for, such Holders Securities will not be rendered invalid by such
purchase, tender or exchange.
Section 5.13. Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs,
including reasonable attorneys fees and expenses, against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any suit instituted by the Company, any Guarantor or the Trustee or, if applicable, in any suit for the enforcement of the right to convert any Security in accordance with its
Section 5.14. Waiver of Usury, Stay or Extension Laws. The Company and each Guarantor covenants (to the extent that it
may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect
the covenants or the performance of this Indenture; and the Company and each Guarantor (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.
Section 6.01. Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default,
(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and as are provided by
the Trust Indenture Act, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and
