                    additions shall include property additions made,
                    constructed or acquired by the Company during the

                    officers' certificate of bondable value of property
                    additions delivered to the Trustee pursuant to this
                    paragraph B, and (ii) each officers' certificate other

                    of any application in connection with which such
                    officers' certificate is delivered to the Trustee, may,
                    unless such property additions are to be acquired in
                    exchange or substitution for bondable property, be
                    certified to the Trustee as property additions in such
                    officers' certificate and in such event shall be
                    treated for all purposes of this Indenture as having
                    been acquired on or before the date of such officers'
                    certificate."
