(b) ENFORCEABILITY; PRIORITY OF SECURITY INTEREST. (i) This Agreement creates a security interest against the Collateral in which the Company now has rights and will

create a security interest which is enforceable against the Collateral in which the Company hereafter acquires rights at the time the Company acquires any such rights; and (ii) the Holders have a perfected security interest in the Collateral, in which the Company now has rights, and will have a perfected security interest in the Collateral in which the Company hereafter acquires rights at the time the Company acquires any such rights, in each case securing the payment and performance of the Secured Obligations except for and subject to Permitted Liens.

SECTION 8. MANAGING HOLDER’S DUTIES. Notwithstanding any provision contained in this Agreement, the Managing Holder shall have no duty to exercise any of the rights, privileges or powers afforded to it and shall not be responsible to the Company or any other Person for any failure to do so or delay in doing so.

Without limiting the generality of the foregoing, the Company agrees that to the extent permitted by applicable law:

The rights and remedies under this Agreement are cumulative and not exclusive of any rights, remedies, powers and privileges that may otherwise be available to any Holder.

SECTION 13. COSTS AND EXPENSES.
