Section 5.01 Remedies. (a) Should any Event of Default (or, with respect to clause (v), a Specified Event of Default) occur and be continuing, the Indenture Trustee is hereby authorized and empowered, at its election, to do any of the following without liability (except to the extent liability results from the gross negligence or willful misconduct of the Indenture Trustee) except to account for money and other property actually received by it, but the Indenture Trustee shall have no duty to exercise any such right, privilege or options and shall not be responsible for any failure to so or delay in so doing:

(i) to transfer and register in its or its nominee’s name the whole or any part of the Collateral, including by means of the completion of the instruments of transfer referred to in Sections 2.01, 2.02 or 3.02(f);

11

(ii) to exercise all voting rights with respect to the Collateral;

(iii) to demand, sue for, collect, receive and give acquittance for any and all cash distributions (including distributions to which any Pledgor would otherwise be entitled pursuant to Section 3.06 of this Agreement) or Monies due or to become due upon or by virtue thereof, and to settle, prosecute or defend any action or proceeding with respect thereto;

(iv) to sell in one or more sales (public or private) the whole or any part of the Collateral or otherwise to transfer or assign the same, in each case, however, to the extent permitted and in the manner provided in the UCC;

(v) to receive and retain all distributions on the Collateral;

(vi) to otherwise enforce and act with respect to the Collateral or the Proceeds as though the Indenture Trustee were the outright owner thereof;

(vii) to exercise all other rights and remedies available under law or in equity; and

(viii) upon the exercise by the Indenture Trustee of any right, privilege or option pertaining to the Pledged Interests, and in connection therewith, the right to deposit and deliver any and all of the Pledged Interests with any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine. The Indenture Trustee is hereby granted a power of attorney to effect the aforesaid registration in the name of the Indenture Trustee or its nominee of the Pledged Interests.

Notwithstanding anything herein to the contrary, unless a Specified Event of Default has occurred and is continuing, the Indenture Trustee shall not, and is not authorized and empowered to, take any action or exercise any right, privilege, remedy or option pursuant to this Section 5.01 or otherwise that would impede, interfere with or otherwise restrict or prevent any Pledgor from receiving or using, free and clear of any Lien created hereby or any security interest granted by such Pledgor to the Indenture Trustee hereunder, for any purpose, any distributions actually made, and any allocations actually made, with respect to the Pledged Interests (whether as a distribution of net cash flow or otherwise).

(b) In the event of any disposition of the Collateral as provided in Section 5.01(a)(iv), the Indenture Trustee shall give to the Pledgors at least ten (10) Business Days prior written notice of the time and place of any public sale of the Collateral or of the time after which any private sale (to the extent permitted by applicable law) or any other intended disposition is to be made, unless a longer period is required by applicable law.

12

be reasonable notice.

(c) The Pledgors recognize that the Indenture Trustee may be unable to effect a public sale of the Collateral, or any part thereof by reason of certain prohibitions contained in the Securities Act, and other applicable laws, but may be compelled to resort to one or more private sales thereof (to the extent permitted by applicable law) to a restricted group of purchasers and may otherwise be required to impose additional limitations on sales as a result thereof. The Pledgors agree that any such private sales may be at prices and other terms less favorable to the seller than if sold at public sales and that such private sales shall not by reason thereof be deemed not to have been made in a commercially reasonable manner. Each Pledgor agrees to use its best efforts to cause the respective Corporations and the LLCs to execute and deliver all such instruments and documents and to do or cause to be done all such other acts and things as may be necessary or, in the reasonable opinion of the Indenture Trustee, advisable (i) to cause the Collateral, or any part thereof, to be exempt from registration under the provisions of the Securities Act, (ii) to amend such instruments and documents which, in the opinion of the Indenture Trustee, are necessary or advisable to meet the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto, and (iii) to make any sales of any portion or all of the Collateral pursuant to this Section 5.01 valid and binding and in compliance with any and all applicable laws, provided that nothing herein shall require or imply that the Pledged Interests are to be registered under the Securities Act or other similar laws. Each Pledgor further agrees to use its best efforts to cause the Corporations to comply with the provisions of the state securities or “Blue Sky” laws of any jurisdiction which the Indenture Trustee shall designate, to the extent that any such laws apply under circumstances under which the Collateral is exempt from registration under the provisions of the Securities Act.

Section 5.02 Limitation on Duties Regarding Collateral.

(a) Beyond the exercise of reasonable care in the custody thereof, the Indenture Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Indenture Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Indenture Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Indenture Trustee in good faith.

After the occurrence and during the continuance of an Event of Default, in the event of any legal action between a Pledgor and the Indenture Trustee hereunder, such Pledgor expressly waives, to the extent permitted by law, any and all rights such Pledgor may have under the law as now constituted or hereafter amended that may constitute a limitation on prejudgment remedies, and the Indenture Trustee may invoke any prejudgment remedy available to it, including garnishment, attachment, foreign attachments and replevin, with respect to the Collateral, to enforce the provisions of this Agreement.

Section 5.04 Application of Proceeds. Except as otherwise provided herein or in the other Transaction Documents, the Indenture Trustee shall apply any Proceeds from time to time held by it and the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable out-of-pocket costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Indenture Trustee hereunder, including, without limitation, reasonable attorney’s fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Indenture Trustee may elect, and only after such application and after the payment by the Indenture Trustee of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Indenture Trustee account for the surplus, if any, to any Pledgor.

Section 5.06 Appointment of Indenture Trustee as Pledgor’s Lawful Attorney. Each Pledgor irrevocably designates, makes, constitutes and appoints the Indenture Trustee (and all Persons designated by the Indenture Trustee) as its true and lawful proxy and attorney-in-fact (coupled with an interest) upon the occurrence and continuance of an Event of Default to take the following actions:

(a) To Endorse Pledgor’s Name. At such time or times hereafter as the Indenture Trustee or its agent in its sole discretion may determine, in such Pledgor’s or the Indenture Trustee’s name, to endorse such Pledgor’s name on any checks, notes, drafts, instruments, documents or any other payment relating to the Collateral or Proceeds which come into the possession of the Indenture Trustee or come under the Indenture Trustee’s control;

14

All reasonable sums expended by the Indenture Trustee in connection with the exercise of any right or remedy provided for herein shall be and shall remain the obligation of the Pledgors. At the option of the Indenture Trustee, all such reasonable sums may be paid from the Collateral or may be advanced by the Indenture Trustee, in which event they shall be deemed to have been advanced to any Pledgor and shall be reimbursed by such Pledgor to the Indenture Trustee within five (5) Business Days after the Indenture Trustee’s written notice to such Pledgor therefor. Such sums shall constitute part of the Obligations.

(b) Pledgor to Reimburse Indenture Trustee for Collateral- Preservation Fees and Taxes. Without limiting the application of Section 5.08(a), each Pledgor shall pay or reimburse the Indenture Trustee for all reasonable, out-of-pocket fees and taxes (but excluding any income or other similar tax imposed on the Indenture Trustee) in connection with preserving the Collateral and the Indenture Trustee’s interest therein, whether through judicial proceedings or otherwise, or in defending or prosecuting any actions, suits or proceedings arising out of or relating to the Collateral, except to the extent such fees and taxes result from the fraud, gross negligence or willful misconduct of the Indenture Trustee. Such fees and taxes will constitute part of the Obligations.

15

Section 5.09 Waiver of Redemption and Deficiency Rights. Each Pledgor hereby waives, to the fullest extent permitted by law, every statute of limitation, any right of redemption, any moratorium or redemption period, and any right which such Pledgor may have to direct the order in which any of the Collateral shall be disposed of in the event of any disposition thereof pursuant hereto, except as otherwise provided herein or in the other Transaction Documents.
