It is acknowledged and agreed that new Subsidiaries of the Borrower or of a Guarantor may become Pledgors hereunder and will be bound hereby simply by executing and delivering to Collateral Trustee a Guarantor Joinder in the form of Exhibit 1.1(G)(1) to the Credit Agreement. In addition, upon such joinder, a new Schedule A hereto shall be provided to the Collateral Trustee showing the pledge of the capital stock or other equity interests in such new Subsidiary and any capital stock or other equity interests that such new Subsidiary owns in any other Person required to be pledged hereunder.

10. No Waiver; Cumulative Remedies.

No failure to exercise, and no delay in exercising, on the part of the Collateral Trustee, any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any further exercise thereof or the exercise of any other right, power or privilege. The remedies herein provided are cumulative and not exclusive of any remedies provided under the Debt Instruments or by Law. Each Pledgor waives any right to require the Collateral Trustee to proceed against any other Person or to exhaust any of the Pledged Collateral or other security for the Secured Obligations or to pursue any remedy in the Collateral Trustee’s power.

11. No Discharge Until Payment in Full of the Secured Obligations.

The pledge, security interests, and other Liens and the obligations of each Pledgor hereunder shall not be discharged or impaired or otherwise diminished by any failure, default, omission, or delay, willful or otherwise, by Collateral Trustee, or any other obligor on any of the Secured Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Pledgor or which would otherwise operate as a discharge of such Pledgor as a matter of law or equity except for, and to the extent of, payment and performance of the Secured Obligations.

10

(f) Any defense, setoff, or counterclaim which may at any time be available to or be asserted by any Pledgor or the Borrower or any other Person with respect to any Debt Instrument or any of the Secured Obligations, other than, and to the extent of, payment and performance of the Secured Obligations; or any discharge by operation of law or release of any Pledgor or the Borrower or any other Person from the performance or observance of any Debt Instrument or any of the Secured Obligations; and

(g) Any other event or circumstance, whether similar or dissimilar to the foregoing, and whether known or unknown, which might otherwise constitute a defense available to, or limit the liability of a guarantor or a surety, including any Pledgor, excepting only full, strict and indefeasible payment and performance of the Secured Obligations in full.
