. Acceleration. If an Event of Default occurs and is continuing, then, and in each and every such case, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Debt Securities of such series then outstanding by notice in writing to the Company (and to the Trustee if given by Holders), may declare the entire outstanding principal amount of all Debt Securities of such series, and the interest accrued thereon, if any, to be immediately due and payable (collectively, the Default Amount). Upon such a declaration, the Default Amount shall be due and payable immediately. Notwithstanding the foregoing, in case of an Event of Default specified in clause 6.01(iv) or clause 6.01(v) of Section 6.01 with respect to a series of Debt Securities, then the principal amount of all the Debt Securities of such series then outstanding and interest accrued thereon, if any, shall be and become immediately due and payable, without any notice or other action by any Holder of the Debt Securities of such series or the Trustee to the full extent permitted by applicable law. The Holders of a majority in aggregate principal amount of the then outstanding Debt Securities of such series by written notice to the Trustee may on behalf of all of the Holders of the Debt Securities of such series rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived.
