other or additional rights or remedies granted to a secured party under the UCC. If, pursuant to Applicable Law, prior notice of any such action is required to be given to Member or any Borrower Subsidiary, Member and each Borrower Subsidiary hereby acknowledge and agree that the minimum time required by such Applicable Law, or if no minimum is specified, of ten (10) Business Days, shall be deemed a reasonable notice period. In addition, to the extent permitted by Applicable Law, Member waives any and all rights that it may have to notice from Collateral Agent or of a judicial hearing in advance of the enforcement of any of Collateral Agent’s rights hereunder.

(b) In addition to the foregoing remedies, Collateral Agent may, after written notice to Member, but shall not be obligated to, cure any Event of Default. Collateral Agent shall be the sole judge of the validity of any adverse claims, taxes, assessments, charges or encumbrances, and the amount to be paid in satisfaction thereof, and of the necessity for, and of the time and manner of doing everything herein authorized to be done, provided Collateral Agent shall be under no obligation to do any such acts or to make any such payments.

(c) If Collateral Agent shall decide to exercise its right, subject to the terms hereof and the other Loan Documents, to sell any or all of the Collateral, and if in the opinion of counsel for Collateral Agent it is necessary to have such Collateral registered under the provisions of the Securities Act of 1933, as amended, or otherwise registered or qualified under any federal or state securities laws or regulations (collectively, the “Securities Laws”), each Borrower Subsidiary and Member will execute and deliver all such instruments and documents which, in the opinion of Collateral Agent, are reasonably necessary to register or qualify such Collateral under the provisions of the Securities Laws and will use reasonable efforts to cause any registration statement relating thereto to become effective and to remain effective for a period of not less than six months from the date of the first public offering of such Collateral and to make all amendments thereto and/or to any related prospectus or similar document which, in the reasonable opinion of Collateral Agent, are necessary, all in conformity with the Securities Laws applicable thereto.

(g) Except as otherwise required by this Pledge Agreement, to the extent permitted under Applicable Law, Member hereby waives all rights and remedies of a debtor or grantor under the UCC or other Applicable Law, and all formalities prescribed by Applicable Law relative to the sale or disposition of the Collateral (other than notice of sale and any other formalities expressly provided in this Pledge Agreement and the other Loan Documents), after the occurrence and during the continuation of an Event of Default.

(h) Member hereby agrees that in respect of any sale of any of the Collateral pursuant to the terms hereof, Collateral Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is reasonably necessary in order to avoid any violation of Applicable Law, or in order to obtain any required approval of the sale or of the purchase by any Governmental Authority or official, and Member further agrees that such compliance shall not, in and of itself, result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall Collateral Agent be liable or accountable to Member for any discount allowed by reason of the fact that such Collateral is sold in compliance with any such limitation or restriction.

(i) If, in the exercise of any of its rights and remedies under this Pledge Agreement, Collateral Agent shall forfeit any of its rights or remedies, whether because of any Applicable Law pertaining to “election of remedies” or otherwise, Member hereby consents to such action by Collateral Agent and, to the extent permitted by Applicable Law, waives any claim based upon such action, even if such action by Collateral Agent shall result in a full or partial loss of any rights of subrogation, indemnification or reimbursement which Member might otherwise have had but for such action by Collateral Agent or the terms herein. Any election of remedies which results in the denial or impairment of the right of Collateral Agent to seek a deficiency judgment against Member in respect of the Collateral shall not, to the extent permitted by Applicable Law, impair Member’s obligation hereunder.

8. Remedies Cumulative; Delay Not Waiver.

(a) No right, power or remedy herein conferred upon or reserved to Collateral Agent or the other Secured Parties is intended to be exclusive of any other right, power or remedy, and every such right, power and remedy shall, to the extent permitted by Applicable Law, be cumulative and in addition to every other right, power and remedy given hereunder or now or hereafter existing at Applicable Law or in equity or otherwise. Resort to

5

any or all security now or hereafter held by Collateral Agent may be taken concurrently or successively and in one or several consolidated or independent judicial actions or lawfully taken nonjudicial proceedings, or both.

(b) No failure or delay on the part of Collateral Agent in exercising any right, power, remedy or privilege hereunder or under any other Loan Document and no course of dealing between Member and Collateral Agent shall operate as a waiver or impairment thereof, nor shall any single or partial exercise of any right, power, remedy or privilege hereunder or under any other Loan Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. No notice to or demand on Member in any case shall entitle Member to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of Collateral Agent to take any other or further action in any circumstances without notice or demand.

9. Marshalling. To the fullest extent permitted by Applicable Law, Member hereby agrees that it shall not invoke any Applicable Law relating to the marshalling of Collateral which might cause delay in or impede the enforcement of Collateral Agent’s rights under this Pledge Agreement or under any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations is outstanding or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the fullest extent permitted by Applicable Law, Member hereby irrevocably waives the benefits of all such laws.
