The Company will pay interest and Liquidated Damages, if any, semi-annually in arrears on February 15 and August 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be February 15, 2006.

The Company will pay interest on the Notes (except defaulted interest) and Liquidated Damages, if any, to the Persons who are registered Holders of Notes at the close of business on the February 1 or August 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, interest and Liquidated Damages, if any, at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest and Liquidated Damages, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Liquidated Damages, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent.

The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

(4) INDENTURE. The Company issued the Notes under an Indenture dated as of August 24, 2005 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

(5) Optional Redemption.

(a) Except as set forth in subparagraphs (a) and (b) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to August 15, 2009. Thereafter, the Company will have the option to redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on August 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date:

(6) Mandatory Redemption.

The Company will not be required to make mandatory redemption payments with respect to the Notes.

(7) Repurchase at Option of Holder.

(a) If there is a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b) If the Company or a Subsidiary consummates any Asset Sales, within 30 days of each date on which the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture

with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes (including any Additional Notes) and other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes (including any Additional Notes) and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company 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” on the reverse of the Notes.

Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

(9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

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

(11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Note Guarantees or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes and Additional Notes, if any, voting as a single class, and any existing default or compliance with any provision of the Indenture, the Note Guarantees or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes and Additional Notes, if any, voting as a single class. Without the consent of any Holder of a Note, the Indenture, the Note Guarantees or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or any Guarantor’s obligations to Holders of the Notes in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, to comply with the requirements of the SEC in order to

effect or maintain the qualification of the Indenture under the Trust Indenture Act, to provide for the Issuance of Additional Notes in accordance with the limitations set forth in the Indenture, or to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Note Guarantee with respect to the Notes.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in 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 or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

(14) SUBORDINATION. Payment of principal, interest and premium and Liquidated Damages, if any, on the Notes is subordinated to the prior payment of Senior Debt on the terms provided in the Indenture.

(15) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

(16) NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator or stockholder, of the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or such Guarantor under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.
