The Grantors and, by accepting the benefits of this Agreement and the other Security Documents, the holders of the Guaranteed Obligations, expressly acknowledge and agree that such instructions set forth in an Act of Guaranteed Debtholders may include the exercise and enforcement of rights, powers and remedies under the Security Documents upon the occurrence and during the continuance of a Default prior to the Collateral Trustee’s receipt of a Notice of Default. If the Collateral Trustee at any time receives a Notice of Default, it shall promptly deliver written notice thereof to the Company and each Secured Debt Representative and shall await direction or instruction, and shall act or decline to act, as directed in an Act of Guaranteed Debtholders in accordance with the Security Documents. The Collateral Trustee shall be entitled to assume conclusively that no Default has occurred and is continuing until it receives a written notice of such.

Further, during a Default Period, prior to taking any foreclosure action under Section 4.01(a), the Collateral Trustee may, as a condition to taking any such foreclosure action, require the receipt of the security or indemnity requested by it pursuant to Section 7.05(d).

Section 4.02. Direction by Act of Guaranteed Debtholders. As to any matters not expressly provided for under this Agreement or the other Security Documents (including, without limitation, matters relating to enforcement and collection of the Guaranteed Obligations), the Collateral Trustee shall not be required to exercise any discretion or to take any action under this Agreement or any of the other Security Documents, or in respect of the Collateral, but shall be required to act or to refrain from acting (and shall be fully protected in acting or refraining from acting) in accordance with the instructions set forth in an Act of Guaranteed Debtholders, provided that neither the foregoing, nor any other provision of this Agreement shall constitute a grant of any rights or Liens by the Grantors that are not set forth in the Security Documents.

(b) No delay or omission of the Collateral Trustee to exercise any right, remedy or power accruing upon any Default shall impair any such right, remedy or power or shall be

(c) In case the Collateral Trustee, at the direction of an Act of Guaranteed Debtholders, shall have proceeded to enforce any right, remedy or power under any Security Document and the proceeding for the enforcement thereof shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Trustee, then and in every such case the Grantors, the Collateral Trustee, the Secured Debt Representatives and the holders of Guaranteed Obligations shall, subject to any determination in such proceeding, severally be restored to their former positions and rights hereunder and under such other Security Documents with respect to the Collateral Trust Estate (including, without limitation, the Collateral Account); and thereafter all rights, remedies and powers of such Collateral Trustee shall continue as though no such proceeding had been taken.

Section 4.05. Waiver of Certain Rights. The Grantor, on behalf of itself and all who may claim through or under it, including, without limitation, any and all subsequent Affiliates, creditors, vendees, assignees and lienors, expressly waives and releases, to the fullest extent permitted by law, any, every and all rights to demand or to have any marshalling of the Collateral Trust Estate upon any enforcement of any Security Document, including, without limitation, upon any sale, whether made under any power of sale herein granted or pursuant to judicial proceedings or upon any foreclosure or any enforcement of any Security Document, and consents and agrees that all the Collateral Trust Estate may be offered and sold as an entirety or in parcels.

Section 4.06. Limitation on Collateral Trustee’s Duties in Respect of Collateral. Beyond the duties set forth in this Agreement, the Collateral Trustee shall not have any duty to the Grantors, any of the Secured Debt Representatives or any other holder of Guaranteed Obligations as to any Collateral in the Collateral Trustee’s possession or control or in the possession or control of any agent or nominee of the Collateral Trustee or as to any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto, except that the Collateral Trustee shall be liable for its failure to exercise ordinary care in the handling of moneys and securities and other property actually received by it.

- 16 -

Section 4.07. Limitation by Law. All rights, remedies and powers provided by this Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Agreement invalid or unenforceable in whole or in part.

Section 4.08. Absolute Rights of Secured Parties and Representatives. Notwithstanding any other provision of this Agreement or any of the other Security Documents to the contrary, each of the Secured Debt Representatives and each of the other holders of Guaranteed Obligations has an absolute and unconditional right to receive payment in cash of all of the Guaranteed Obligations owing to it when the same becomes due and payable and at the time and place and otherwise in the manner set forth in the applicable Secured Debt Document, subject to the provisions of the applicable Secured Debt Document, and the right of each such Secured Debt Representative and each such other holder of Guaranteed Obligations to institute proceedings for the enforcement of such payment on or after the date such payment becomes due and to assert its position as a secured creditor in a proceeding under the Bankruptcy Law in which the Grantor is a debtor, and the obligation of the Grantor to pay all of the Guaranteed Obligations at the time and place expressed in the applicable Secured Debt Document, shall not be impaired or affected by this Agreement or the other Security Documents. In addition, the right of any Secured Debt Representative, on behalf of itself or on behalf of any such holders of Guaranteed Obligations or the right of holders of Guaranteed Obligations, to receive payment or security from sources other than the Collateral shall not be, and is not hereby, impaired or affected in any manner. Without limiting the generality of the foregoing provisions of this Section 4.08, no Secured Debt Representative, on behalf of itself or on behalf of any holders of Guaranteed Obligations, and no other holder of Guaranteed Obligations shall be obligated to share with any other Secured Debt Representative or any other holders of Secured Obligations any proceeds of any collateral, guarantee or right of setoff other than pursuant to, and to the extent expressly required under, this Agreement, the other Security Documents and/or the Secured Debt Documents to which it is a party; nor shall the right of any Secured Debt Representative or any holder of Guaranteed Obligations to receive its share of any amounts maintained in the Collateral Account, if any, or any proceeds of any of the Collateral, or any part thereof, under the terms of this Agreement and the other Security Documents be diminished or affected in any way by its right to receive proceeds of any other collateral or right of setoff, or payment upon a guarantee or from any other source (except to the extent expressly provided for in the Order of Application and the definition of “Equally and Ratably”).
