To the extent that the aggregate amount of Notes and such Other Pari Passu Lien Obligations tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuers

may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Notes or the Other Pari Passu Lien Obligations surrendered by such Holders and holders thereof exceeds the amount of Excess Proceeds or Excess ABL Proceeds, as applicable, the Issuers shall select the Notes and such Other Pari Passu Lien Obligations to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Other Pari Passu Lien Obligations tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. After the Issuers or any Restricted Subsidiary have applied the Net Proceeds from any Asset Sale of any assets that do not constitute ABL Collateral, the balance of such Net Proceeds, if any, from such Asset Sale shall be released by the Notes Collateral Agent to the Issuers or such Restricted Subsidiary for use by the Issuers or such Restricted Subsidiary for any purpose not prohibited by the terms of the Indenture. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Issuers prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuers need not exchange or register the transfer of any Note or portion of a Note selected for redemption or tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer, an Asset Sale Offer or other tender offer, in whole or in part, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuers need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

10.    PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

11.    AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture, the Guarantees or the Notes may be amended or supplemented as provided in the Indenture.

12.    DEFAULTS AND REMEDIES. The Events of Default relating to the Notes are defined in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount of the then total outstanding Notes may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the Notes or the Guarantees except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of

any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if and so long as it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences under the Indenture (except a continuing Default in the payment of interest on, premium, if any, or the principal of any Note held by a non-consenting Holder) and rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest, if any, or premium that has become due solely because of the acceleration) have been cured or waived. The Issuers and each Guarantor (to the extent that such Guarantor is so required under the Trust Indenture Act) is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuers are required within five (5) Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such event.

13.    AUTHENTICATION. This Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee.

14.    GOVERNING LAW. THE INDENTURE, THE NOTES AND ANY GUARANTEE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

15.    CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.
