Limitation on Guarantees of Indebtedness by Restricted Subsidiaries The Issuer shall not permit any of its Wholly-Owned Subsidiaries that are Restricted Subsidiaries (and non-Wholly-Owned Subsidiaries if such non-Wholly-Owned Subsidiaries guarantee other capital markets debt securities of the Issuer, the Co-Issuer or any Guarantor), other than a Guarantor, the Co-Issuer, a Foreign Subsidiary or a Securitization Subsidiary, to guarantee the payment of any Indebtedness of the Issuer, the Co-Issuer or any Guarantor unless: (a) such Restricted Subsidiary within 60 days after the guarantee of such Indebtedness executes and delivers a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Issuer, the Co-Issuer or any Guarantor, if such Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s Guarantee, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes; and (b) such Restricted Subsidiary waives and shall not in any manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other applicable rights against the Issuer or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee; provided that this Section 4.15 shall not be applicable to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary. The Issuer may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to be a Guarantor to become a Guarantor, in which case such Subsidiary shall not be required to comply with the 60 day period described in clause (a) of this Section 4.15.
