of the Indenture The Holders of a majority in aggregate Liquidation Amount of the Preferred Securities may, on behalf of the Holders of all the Preferred Securities, waive any past default under the Indenture, except a default in the payment of principal or interest (unless such default has been cured and a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been deposited with the Debenture Trustee) or a default in respect of a covenant or provision which under the Indenture cannot be modified or amended without the consent of the holder of each outstanding Debenture. No such rescission shall affect any subsequent default or impair any right consequent thereon. Upon receipt by the Property Trustee of written notice declaring such an acceleration, or rescission and annulment thereof, by Holders of the Preferred Securities all or part of which is represented by Book-Entry Preferred Securities Certificates, a record date shall be established for determining Holders of Outstanding Preferred Securities entitled to join in such notice, which record date shall be at the close of business on the day the Property Trustee receives such notice. The Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to join in such notice, whether or not such Holders remain Holders after such record date; provided, that, unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having joined in such notice prior to the day which is 90 days after such record date, such notice of declaration of acceleration, or rescission and annulment, as the case may be, shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new written notice of declaration of acceleration, or rescission and annulment thereof, as the case may be, that is identical to a written notice which has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 5.14(b).
