(7) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part of any mortgage existing at the date of this Indenture or any mortgage referred to in the foregoing clauses (1) through (6), inclusive, provided, however, that the principal amount of indebtedness secured thereby shall not exceed the principal amount of indebtedness so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property (plus improvements and construction on such property), shares of capital stock or indebtedness which was subject to the mortgage so extended, renewed or replaced.
(c) Notwithstanding the provisions of paragraph (a) of this Section 4.06, the Company or any Restricted Subsidiary may, without equally and ratably securing the Securities, issue, incur, assume or guarantee indebtedness secured by a mortgage not excepted by clauses (1) through (7) of paragraph (b) of this Section 4.06, if the aggregate amount of such indebtedness, together with all other indebtedness of, or indebtedness guaranteed by, the Company and its Restricted Subsidiaries existing at such time and secured by mortgages not so excepted and the Attributable Debt in respect of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions permitted by clause (i) of Section 4.08 and other than Sale and Lease-Back Transactions the proceeds of which have been applied in accordance with clause (iii) of Section 4.08), does not at the time exceed 15% of Consolidated Net Tangible Assets.
Section 4.07 Restrictions on Future Liens.
If, on or following the date of the Indenture, any indebtedness of the Company and/or any Restricted Subsidiary (as defined, solely for purposes of this Section 4.07, in the Term Loan Facility) with an outstanding aggregate principal amount in excess of $10.0 million is secured on a junior lien basis to the Term Loan Facility or ABL Credit Facility, then within 15 Business Days of the provision of such security, the Company will cause the Securities to be secured on an equal and ratable basis with such indebtedness for so long as such indebtedness is so secured. For the avoidance of doubt, to the extent that the Company or any such Restricted Subsidiary issues or incurs any indebtedness that is secured (or any indebtedness becomes secured) on an equal or senior lien basis to the Term Loan Facility or ABL Credit Facility, the immediately preceding sentence shall not apply with respect to such collateral (it being understood that the ability to control remedies or take actions pursuant to any intercreditor agreement relating to the Term Loan Facility or ABL Credit Facility shall not impact lien priority).
Without limiting the foregoing or any other provision of this Indenture, the Company, at its sole cost and expense, will, and will cause such Restricted Subsidiaries to, execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register, as applicable, any and all such further acts, deeds, conveyances, security agreements, joinders, account control agreements, assignments, financing statements and continuations thereof, termination statements, notices of assignment, transfers, certificates, assurances and other instruments, consents, authorizations, approvals and orders, and shall take all further action, as may be required from time to time in order to carry out the terms and provisions of this Section 4.07; perfect and maintain the validity, enforceability, effectiveness and priority of any of the liens created pursuant to this Section 4.07 (it being understood that, to the extent that any such lien secures a guaranty, the Securities shall also be guaranteed and secured to a similar extent); and assure, convey, grant, assign, transfer, preserve, protect and confirm to the applicable collateral agent any of the rights intended to be granted to such collateral agent under this Section or any collateral documents executed in connection with compliance with this Section 4.07.
