At any time while the Trustee shall be holding cash or Bonds deposited with it or while Available Net Property Additions have been allocated in satisfaction of the Replacement Deficit and not reinstated, in all cases pursuant to the provisions of this Section, the Company may: 1. substitute Outstanding Bonds or Available Net Property Additions for such cash, Outstanding Bonds for Available Net Property Additions so allocated, or Available Net Property Additions for Bonds so deposited, the basis of substitution being the same as the basis for deposit hereinbefore set forth; Bonds may be substituted for cash or for Available Net Property Additions upon written application made by the Company accompanied by an Officers' Certificate substantially similar to the Officers' Certificate required in connection with the deposit of Bonds with the Trustee; Available Net Property Additions may be substituted for cash or for Bonds upon written application made by the Company accompanied by Certificates substantially similar to the Certificates required in connection with the allocation of Available Net Property Additions in satisfaction of a Replacement Deficit; 2. withdraw cash or Bonds upon written application therefor accompanied by an Officers' Certificate stating (i) the amount of cash or the aggregate principal amount of Bonds to be withdrawn; (ii) the Available Replacement Credit on the date of the Certificate, which shall at least equal the amount of the cash or the aggregate principal amount of the Bonds to be withdrawn, and the computation thereof; and (iii) that to the best of the knowledge and belief of such Officers the Company is not in default in the performance and observance of any terms, covenants, and conditions of the Indenture; 3. reinstate the Cost or Fair Value of Available Net Property Additions allocated in satisfaction of any Replacement Deficit or for the withdrawal of cash or of Bonds as above provided in an amount equal to any Available Replacement Credit upon the filing with the Trustee of an Officers' Certificate stating the Available Replacement Credit and the amount of the Available Net Property Additions to be reinstated and that the Company is not in default in the performance and observance of any terms, covenants and conditions of the Indenture, and thereupon the Available Net Property Additions so reinstated may be made the Basis for Action or Credit hereunder in all Certificates of Available Net Property Additions thereafter filed with the Trustee. Except as hereinbefore provided for the withdrawal of cash or Bonds, any cash deposited with the Trustee pursuant to the provisions of this Section shall be held and disposed of pursuant to the provisions of Section 8.02 of the Original Indenture, and any Bonds deposited with the Trustee shall be held by the Trustee and while so held shall not be made the basis for the certification of Bonds, the withdrawal, use or application of cash, or the release of property under the provisions of the Indenture or used to satisfy a Replacement Deficit or to satisfy any other requirements of the Indenture. No payment by way of principal, interest, or otherwise on any Bonds held by the Trustee shall be made or demanded by the Trustee while so held. ARTICLE VIII. MISCELLANEOUS PROVISIONS. Section 8.01.
