. Waiver of Past Defaults. Holders of at least a majority in principal amount of the outstanding Debt Securities of any series, by notice to the Trustee, may waive an existing Default or Event of Default and its consequences, except (i) a Default in the payment of principal of or interest on any Debt Securities of such series as specified in clauses 6.01(i) or 6.01(ii) of Section 6.01 or (ii) a Default in respect of a covenant or provision that under Section 9.02 cannot be modified or amended without the consent of the Holder of each outstanding Debt Securities of such series affected. Upon any such waiver, such Default shall cease to exist with respect to the Debt Securities of such series, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.
