(7) except as permitted by this Indenture, any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee;

(b) The first paragraph of Section 5.2 of the Original Indenture is amended in its entirety with respect to the 8.5% Notes to read as follows:

Section 5.2. Acceleration of Maturity; Rescission and Annulment.

If an Event of Default (other than an Event of Default specified in Section 5.1(8) or 5.1(9)) with respect to the 8.5% Notes occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding 8.5% Notes may declare the principal amount of all the 8.5% Notes, together with all accrued but unpaid interest thereon, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount, together with all accrued but unpaid interest thereon, shall become immediately due and

payable. If an Event of Default specified in Section 5.1(8) or 5.1(9) with respect to the 8.5% Notes occurs, the principal amount of all the 8.5% Notes, together with all accrued but unpaid interest thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.

(3) immediately after such transaction, no Default or Event of Default exists; and

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.1. Without Consent of Holders of 8.5% Notes.

Notwithstanding Section 9.2 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture as it relates to the 8.5% Notes or the 8.5% Notes or the Subsidiary Guarantees without the consent of any Holder of a 8.5% Note:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated 8.5% Notes in addition to or in place of certificated 8.5% Notes;

(3) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the 8.5% Notes and Subsidiary Guarantees by a successor to the Company or such Guarantor pursuant to Article Eight or Article Fourteen of this Indenture;

(4) to make any change that would provide any additional rights or benefits to the Holders of the 8.5% Notes or that does not adversely affect the legal rights hereunder of any Holder;

(5) to secure the 8.5% Notes or the Subsidiary Guarantees pursuant to the requirements of Section 10.13 of this Indenture;

(6) to add any Guarantor to or release any Guarantor from its Subsidiary Guarantee, in each case pursuant to Article Fourteen of this Indenture;

(7) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

(9) to provide for the issuance of Additional 8.5% Notes in accordance with the limitations set forth in this Indenture as of the date hereof; or

(10) to provide for a successor Trustee with respect to the 8.5% Notes pursuant to Article Six of this Indenture.

Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.6 of this Indenture, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Nothing in this Section 9.1 shall require the consent of any Holder to any amendment or supplement to the Original Indenture insofar as it relates to any series of Securities other than the 8.5% Notes.

Section 9.2. With Consent of Holders of 8.5% Notes.

The Company, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Section 10.14 and 10.16 of this Indenture) and the 8.5% Notes and the Subsidiary Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then Outstanding 8.5% Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the 8.5% Notes), and, subject to Sections 5.8 and 5.13 of this Indenture, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on, the 8.5% Notes and except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the 8.5% Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then Outstanding 8.5% Notes voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the 8.5% Notes). However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.2 may not (with respect to any 8.5% Notes held by a non-consenting Holder):

(1) reduce the principal amount of 8.5% Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any 8.5% Note or alter any of the provisions with respect to the redemption of the 8.5% Notes; provided, however, that any purchase or repurchase of 8.5% Notes, including pursuant to Sections 10.14 and 10.16 hereof, shall not be deemed a redemption of the 8.5% Notes;

(3) reduce the rate of or change the time for payment of interest, including default interest, on any 8.5% Note;

(4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or interest on, the 8.5% Notes (except a rescission of acceleration of the 8.5% Notes by the Holders of at least a majority in aggregate principal amount of the then Outstanding 8.5% Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any 8.5% Note payable in money other than that stated in the 8.5% Notes;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults with respect to the 8.5% Notes or the rights of Holders of 8.5% Notes to receive payments of principal of, or interest or premium if any, on, the 8.5% Notes;

(7) waive a redemption payment with respect to any 8.5% Note; provided, however, that any purchase or repurchase of 8.5% Notes, including pursuant Sections 10.14 and 10.16 hereof, shall not be deemed a redemption of the 8.5% Notes;

(8) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(9) make any change in the preceding amendment, supplement and waiver provisions.

Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of 8.5% Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.6 of this Indenture, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

It is not be necessary for the consent of the Holders of 8.5% Notes under this Section 9.2 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company will mail to the Holders of 8.5% Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 9.3. Compliance with Trust Indenture Act.

Every amendment or supplement to this Indenture, or the 8.5% Notes or the Subsidiary Guarantees will be set forth in an amended or supplemental indenture that complies with the TIA as then in effect.

Section 9.4. Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of an 8.5% Note is a continuing consent by the Holder of an 8.5% Note and every subsequent Holder of an 8.5% Note or portion of an 8.5% Note that evidences the same debt as the consenting Holder’s 8.5% Note, even if notation of the consent is not made on any 8.5% Note. However, any such Holder of an 8.5% Note or subsequent Holder of an 8.5% Note may revoke the consent as to its 8.5% Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

The Company may fix a record date for determining which Holders must consent to such amendment, supplement or waiver in accordance with Section 1.5 of this Indenture.

Section 9.5. Notation on or Exchange of 8.5% Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any 8.5% Note thereafter authenticated. The Company in exchange for all 8.5% Notes may issue and the Trustee shall, upon receipt of a Company Order, authenticate new 8.5% Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new 8.5% Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.6. Trustee to Sign Amendments.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article Nine if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 6.1 of this Indenture) will be fully protected in relying upon, in addition to the documents required by Section 1.3 of this Indenture, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

SECTION 6. Amendments to Article Ten of the Original Indenture.

(a) Section 10.1 of the Original Indenture is amended with respect to the 8.5% Notes by adding the following paragraphs thereto:

Principal, premium, if any, and interest shall be considered paid on the date due if by 11:00 a.m., New York City time, on such date the Trustee or the Paying Agent holds in accordance with this Indenture Dollars, in immediately available funds, sufficient to pay all principal, premium, if any, and interest then due.

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the rate specified therefor in the 8.5% Notes, and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest from time to time on demand at the same rate to the extent lawful.

(b) The second paragraph of Section 10.3 of the Original Indenture is amended with respect to the 8.5% Notes by inserting the words “11:00 a.m., New York City time, on” immediately before the words “each due date” appearing in the second line of such paragraph.

(c) Article Ten of the Original Indenture is amended with respect to the 8.5% Notes by adding Sections 10.8 through 10.20, inclusive, as follows:

Section 10.8. Payments for Consent.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of 8.5% Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the 8.5% Notes unless such consideration is offered to be paid and is paid to all Holders of the 8.5% Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 10.9. Commission Reports; Default Notices.

(a) Whether or not required by the rules and regulations of the SEC, so long as any 8.5% Notes are outstanding, the Company shall furnish to the Holders of 8.5% Notes or cause the Trustee to furnish to the Holders of 8.5% Notes, within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such reports; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

All such reports shall be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K shall include a report on the Company’s consolidated financial statements by the Company’s certified independent accountants. In addition, the Company shall file a copy of each of the reports referred to in clauses (1) and (2) of this Section 10.9(a) with the SEC for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the SEC will not accept such a filing) and shall post the reports on its website within those time periods.

(b) If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue filing the reports specified in the preceding paragraph with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company shall not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company shall post the reports referred to in Section 10.9(a) on its website within the time periods that would apply if the Company were required to file those reports with the SEC.

(c) In addition, the Company and the Guarantors agree that, for so long as any 8.5% Notes remain outstanding, at any time they are not required to file the reports required by this Section 10.9 with the SEC, the Company and the Guarantors shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(d) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to this Section 10.9 shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article Eight or Article Ten hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation.

(e) So long as any of the 8.5% Notes are outstanding, the Company will deliver to the Trustee, forthwith upon any officer of the Company becoming aware of any Default or Event of Default with respect to the 8.5% Notes, an Officer’s Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

Section 10.10. Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur” or an “incurrence”) any Indebtedness, and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any Disqualified Stock; provided, however, that the Company or any Guarantor may incur Indebtedness or issue Disqualified Stock, if the Consolidated Interest Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis, including a pro forma application of the net proceeds therefrom, as if the additional Indebtedness or Disqualified Stock had been incurred or issued at the beginning of such four-quarter period.

(b) Notwithstanding the foregoing, the provisions of Section 10.10(a) hereof will not prohibit the incurrence of any Permitted Indebtedness.

(c) The Company shall not incur any Indebtedness (including Permitted Indebtedness) that is contractually subordinated in right of payment to any other Indebtedness of the Company, unless such Indebtedness is also contractually subordinated in right of payment to the 8.5% Notes on substantially identical terms; provided, however, that solely for the avoidance of doubt and without any other implication, no Indebtedness of the Company shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured.

(d) For purposes of determining compliance with this Section 10.10, in the event that an item of proposed Indebtedness or Disqualified Stock meets the criteria of more than one of the categories contained in clauses (1) through (15) of the definition of Permitted Indebtedness, or is entitled to be incurred pursuant to Section 10.10(a) hereof, the Company will be permitted to classify such item of Indebtedness or Disqualified Stock on the date of its incurrence or issuance, or later reclassify all or a portion of such item of Indebtedness or Disqualified Stock, in any manner that complies with this Section 10.10. The accrual of interest, the accumulation of dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock, will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 10.10; provided, in each such case, that the amount thereof is included in Consolidated Interest Expense as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 10.10 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(A) the fair market value of such asset at the date of determination; and

(B) the amount of the Indebtedness of the other Person; and

(3) the principal amount of the Indebtedness, in the case of any other Indebtedness.

Section 10.11. Restricted Payments.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including any such payment in connection with any merger or consolidation involving the Company) or to the direct or indirect holders of the Company’s Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company);

(2) purchase, redeem or otherwise acquire or retire for value (including without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company (other than any such Equity Interests owned by the Company or any Restricted Subsidiary of the Company);

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, any Subordinated Indebtedness (other than intercompany Indebtedness between or among the Company and its Restricted Subsidiaries), except a payment of interest or principal at Stated Maturity (or within one year thereof); or

(4) make any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”),

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence of such Restricted Payment;

(2) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in Section 10.10(a) hereof; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (the amount expended for such purposes, if other than cash, being the fair market value on the date of transfer or issue), is less than the sum of the following amounts, without duplication:

(A) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from July 1, 2008 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(B) 100% of (x) the aggregate net cash proceeds and the fair market value of any non-cash proceeds received by the Company since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale of Disqualified Stock or convertible or exchangeable debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company), (y) the amount by which Indebtedness of the Company or any Restricted Subsidiary is reduced on the Company’s consolidated balance sheet upon the conversion or exchange after the Issue Date of any such Indebtedness into or for Equity Interests of the Company (other than Disqualified Stock), and (z) the aggregate net cash proceeds, if any, received by the Company or any of its Restricted Subsidiaries upon any conversion or exchange described in clause (x) or (y) above; plus

(C) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or Cash Equivalents, or otherwise is liquidated or repaid for cash or Cash Equivalents, an amount equal to such cash or Cash Equivalents (less the cost of disposition, if any); plus

(D) the amount equal to the net reduction in Investments in Unrestricted Subsidiaries after the Issue Date resulting from (A) payments of dividends or interest or other transfers of assets to the Company or any Restricted Subsidiary from Unrestricted Subsidiaries, (B) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries or (C) the receipt of proceeds by the Company or any Restricted Subsidiary from the sale or other disposition of any portion of any Investment in an Unrestricted Subsidiary’ plus

(E) $218.8 million.

(b) The provisions of Section 4.07(a) hereof will not prohibit:

(1) the payment of any dividend within 60 days after the date of declaration thereof if at said date of declaration such payment would have complied with the provisions of this Indenture;

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock) or from the substantially concurrent contribution (other than by a Subsidiary of the Company) of capital to the Company in respect of its Equity Interests (other than Disqualified Stock); provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition shall be excluded from clause (3)(B) of Section 4.07(a) hereof;

(3) the defeasance, redemption, repurchase, retirement or other acquisition of Subordinated Indebtedness of the Company or any Guarantor with the net cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness;

(4) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to (i) the holders of its common Equity Interests on a pro rata basis or (ii) the Company or a Subsidiary of the Company;

(5) so long as no Default or Event of Default shall have occurred and be continuing, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company held by any future, present or former employee or director (or any of their respective heirs or estates or permitted transferees) of the Company or any of the Company’s Restricted Subsidiaries pursuant to any agreements (including employment agreements) or management equity plan or stock option plan or any other management or employee benefit plan or agreement (including any management equity subscription agreement, stock option agreement or similar written arrangement) approved by the Board of Directors; provided, that the aggregate Restricted Payments made under this clause (e) do not exceed in any calendar year $5.0 million (with unused amounts in any calendar year being carried over to succeeding calendar years subject to a maximum of $10.0 million in any calendar year);

(6) repurchases, redemptions or other acquisitions or retirements for value of Equity Interests of the Company deemed to occur upon exercise or exchange of warrants, options or rights to acquire Equity Interests if such Equity Interests represent a portion of the exercise or exchange price of such warrants, options or rights, and any repurchases, redemptions or other acquisitions or retirements for value of Equity Interests made in lieu of withholding taxes in connection with any exercise or exchange of warrants, options or rights to acquire Equity Interests;

(7) payments or distributions to dissenting shareholders pursuant to applicable law in connection with a merger, consolidation or transfer of assets that complies with the provisions of Section 8.1 hereof;

(8) cash payments in lieu of the issuance of fractional shares;

(9) the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any Restricted

Subsidiary of the Company, or any class or series of preferred stock of a Restricted Subsidiary of the Company, in each case issued after the Issue Date in accordance with the Consolidated Interest Coverage Ratio test described in Section 10.10(a) hereof and

(10) other Restricted Payments not to exceed $25.0 million in the aggregate since the Issue Date.

In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date in accordance with clause (3) of Section 10.11(a), amounts expended pursuant to clauses (2), (3), (4), (6), (7), (8), (9) and (10) of this Section 10.11(b) shall be excluded from the calculation, and amounts expended pursuant to clauses (1) and (5) of this Section 10.10(b) shall be included in the calculation.

(c) The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the greater of (1) the net book value of such Investments at the time of such designation and (2) the fair market value of such Investments at the time of such designation. Such designation will only be permitted if such Restricted Payment would be permitted at such time.

(d) The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any non-cash Restricted Payment shall be determined in the manner contemplated by the definition of the term “fair market value.”

Section 10.12. Dividend and Other Payment Restrictions Affecting Subsidiaries.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to:

(1) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock;

(2) make loans or advances, or pay any Indebtedness owed, to the Company or any of its Restricted Subsidiaries; or

(3) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

(b) The restrictions in Section 10.12(a) hereof will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements or instruments governing Existing Indebtedness or Capital Stock as in effect on the Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements or instruments; provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements or instruments on the Issue Date;

(2) this Indenture, the 8.5% Notes and the Subsidiary Guarantees;

(3) applicable law, rule, regulation or order;

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(5) any encumbrance or restriction consisting of customary non-assignment provisions (including provisions forbidding subletting) in leases governing leasehold interests to the extent such provisions restrict the transfer of the lease, the property leased thereunder or the other interests therein;

(6) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 10.12(a) hereof;

(7) customary provisions in bona fide contracts for the sale of property or assets;

(8) any agreement for the sale or other disposition of a Subsidiary that restricts distributions by that Subsidiary pending its sale or other disposition;

(9) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(10) any encumbrance or restriction contained in the terms of any Indebtedness or preferred stock, or any agreement pursuant to which such Indebtedness or preferred stock was incurred or issued, if such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments on the 8.5% Notes, as determined in good faith by the Company’s Board of Directors, whose determination shall be conclusive;

(11) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness or preferred stock being refinanced; and

(12) secured Indebtedness that limits the right of the debtor to dispose of the assets securing such Indebtedness and any encumbrance or restriction contained in related security agreements, mortgages or purchase money agreements.

Section 10.13. Liens.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create, incur, assume or suffer to exist, any Lien (except Permitted Liens) on any asset owned on the Issue Date or acquired after the Issue Date, securing:

(1) any Indebtedness of the Company or such Restricted Subsidiary (if it is not also a Guarantor), unless prior to, or contemporaneously therewith, the 8.5% Notes are equally and ratably secured; or

(2) any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantee of such Guarantor is equally and ratably secured;

provided, however, that if such Indebtedness is expressly subordinated to the 8.5% Notes or the Subsidiary Guarantees, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the 8.5% Notes or the Subsidiary Guarantees, as the case may be, with the same relative priority as such Indebtedness has with respect to the 8.5% Notes or the Subsidiary Guarantees.

Section 10.14. Asset Sales.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale (excluding an Event of Loss for this purpose) unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received by the Company or such Restricted Subsidiary, as the case may be, from the Asset Sale is in the form of (A) cash or Cash Equivalents or (B) properties and capital assets to be used by the Company or any Restricted Subsidiary in the Principal Business, or Capital Stock of a Person engaged in the Principal Business which becomes a Restricted Subsidiary of the Company, or any combination thereof (collectively, the “Cash Consideration”):

provided, however, that the amount of (a) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the 8.5%

Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to (1) a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability or (2) an assignment agreement that includes, in lieu of such a release, the agreement of the transferee or its parent company to indemnify and hold harmless the Company or such Restricted Subsidiary from and against any loss, liability or cost in respect of such assumed liability (provided, however, that such indemnifying party (or its long term debt securities) shall have an Investment Grade Rating (with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating) at the time the indemnity is entered into) and (b) any non-Cash Consideration received by the Company or such Restricted Subsidiary from such transferee that is converted by the Company or such Restricted Subsidiary into cash within 90 days of the receipt thereof (to the extent of the cash received) shall be deemed to be cash for purposes of this Section 10.14(a).

(b) Notwithstanding the foregoing, the 75% limitation referred to in Section 10.14(a) shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.

(c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any such Restricted Subsidiary may apply such an amount equal to those Net Proceeds, at its option, to:

(1) prepay, repay, defease, redeem, purchase or otherwise retire any Secured Indebtedness, and, if the Secured Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2) make a capital expenditure; or

(3) acquire assets used in the Principal Business or to acquire all or substantially all of the assets of, or any Capital Stock of, another Person engaged in the Principal Business.

Notwithstanding the foregoing, if within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) enters into a binding written agreement irrevocably committing the Company or such Restricted Subsidiary to an application of funds of the kind described in clause (2) or (3) of this Section 10.14(c), and as to which the only condition to closing is the receipt of required governmental approvals, the Company or such Restricted Subsidiary shall be deemed not to be in violation of this Section 10.14(c). Any Net Proceeds that are applied pursuant to clause (2) or (3) of this Section 10.14(c) pursuant to any such binding agreement shall be deemed to have been applied for such purpose within such 365-day period so long as they are so applied within two years after the date of receipt of such Net Proceeds.

(d) Pending the final application of any Net Proceeds, the Company or any such Restricted Subsidiary may temporarily reduce outstanding revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture.

(e) An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in preceding paragraphs of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $30.0 million, the Company shall make an Asset Sale Offer to all Holders of 8.5% Notes and all holders of Pari Passu Indebtedness to purchase the maximum principal amount of 8.5% Notes and such Pari Passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of the Indebtedness to be purchased plus accrued and unpaid interest to the date of purchase (subject to the rights of Holders on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the date of purchase), and will be payable in cash, in accordance with the procedures set forth in this Indenture, in the case of the 8.5% Notes, or in the instruments governing the terms of the Pari Passu Indebtedness, in the case of such Pari Passu Indebtedness; provided, however, that, if the Company is required to apply such Excess Proceeds to repurchase, or to offer to repurchase, any Pari Passu Indebtedness, the Company shall only be required to offer to repurchase the maximum principal amount of 8.5% Notes that may be purchased out of the amount of such Excess Proceeds multiplied by a fraction, the numerator of which is the aggregate principal amount of 8.5% Notes outstanding and the denominator of which is the aggregate principal amount of 8.5% Notes outstanding plus the aggregate principal amount of such Pari Passu Indebtedness outstanding. To the extent that the aggregate principal amount of 8.5% Notes tendered pursuant to an Asset Sale Offer is less than the amount that the Company is required to repurchase, the Company may use the difference between such amounts for purposes not otherwise prohibited by this Indenture. If the aggregate principal amount of 8.5% Notes surrendered by Holders thereof exceeds the amount that the Company is required by this Section 10.14 to repurchase, the Trustee shall select the 8.5% Notes to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(f) Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Sections 8.1 and/or 10.16 and not by this Section 10.14.

(g) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with each repurchase of 8.5% Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 10.14 (or compliance with the provisions of this Section 10.14 would constitute a violation of any such laws or regulations), the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 10.14 by virtue of such compliance.

(h) In the event that, pursuant to the preceding provisions of this Section 10.14, the Company is required to commence an offer to all Holders to purchase 8.5% Notes (an “Asset Sale Offer”), it will follow the procedures specified below.

(i) The Asset Sale Offer shall be made to all Holders and all holders of Pari Passu Indebtedness containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of 8.5% Notes and such other Pari Passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all 8.5% Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any 8.5% Notes so purchased will be made in the same manner as interest payments are made.

(j) Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender 8.5% Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 10.14 and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the Purchase Date;

(3) that any 8.5% Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Company defaults in making such payment, any 8.5% Note or portion thereof accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a 8.5% Note purchased pursuant to an Asset Sale Offer may elect to have 8.5% Notes purchased in integral multiples of $1,000 only;

(6) that Holders electing to have 8.5% Notes purchased pursuant to any Asset Sale Offer will be required to surrender the 8.5% Note, with the form entitled “Option of Holder to Elect Purchase” attached to the 8.5% Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(7) that Holders will be entitled to withdraw their election if the Company, the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the 8.5% Note the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such 8.5% Note purchased;

(8) that, if the aggregate principal amount of 8.5% Notes and any Pari Passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Company will select the 8.5% Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis based on the principal amount of 8.5% Notes and such Pari Passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only 8.5% Notes in denominations of $1,000, or integral multiples thereof, will be purchased); and

(9) that Holders whose 8.5% Notes were purchased only in part will be issued new 8.5% Notes equal in principal amount to the unpurchased portion of the 8.5% Notes surrendered (or transferred by book-entry transfer).

(k) No later than 11:00 a.m., New York City time, on the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of 8.5% Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all 8.5% Notes tendered, and will deliver or cause to be delivered to the Trustee the 8.5% Notes properly accepted together with an Officers’ Certificate stating that such 8.5% Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 10.14. The Company, the depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the 8.5% Notes tendered by such Holder and accepted by the Company for purchase, and the Company, will promptly issue a new 8.5% Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new 8.5% Note to such Holder, in a principal amount equal to any unpurchased portion of the 8.5% Note surrendered. Any 8.5% Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Section 10.15. Transactions with Affiliates.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing an “Affiliate Transaction”), unless:

(1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if there is no such comparable transaction, on terms that are fair and reasonable to the Company or such Restricted Subsidiary; and

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, a resolution of the Board of Directors certifying that such Affiliate Transaction complies with clause (1) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $30.0 million, an opinion as to the fairness to the Company or the relevant Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm that is, in the judgment of the Board of Directors, qualified to render such opinion and is independent with respect to the Company.

(b) Notwithstanding the preceding, the following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 10.15(a) hereof:

(1) reasonable fees and compensation paid to or for the benefit of any employee, officer or director of the Company or any of its Subsidiaries, and any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Subsidiaries existing on the Issue Date, or entered into thereafter in the ordinary course of business, and any indemnities or other transactions permitted or required by bylaw, statutory provisions or any of the foregoing agreements, plans or arrangements;

(2) transactions between or among the Company and its Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) any Permitted Investments and any Restricted Payments that do not violate the provisions of Section 10.11 of this Indenture;

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of any capital contribution from, any Affiliate of the Company;

(6) the payment of reasonable directors’ fees to directors of the Company or any of its Subsidiaries;

(7) any contracts, agreements or understandings existing as of the Issue Date and any amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto or any replacement agreement thereof so long as any such

amendment or replacement agreement is not more disadvantageous to the Holders of the 8.5% Notes in any material respect than the original agreement as in effect on the Issue Date); and

(8) transactions with customers, clients, suppliers, joint venture partners or purchasers or sellers of goods or services, in each case in the ordinary course of business (including pursuant to joint venture agreements) and otherwise in compliance with the terms of this Indenture and which comply with the terms of clause (2) of Section 10.15(a).

Section 10.16. Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, Holders of 8.5% Notes will have the right to require the Company to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder’s 8.5% Notes at a purchase price in cash equal to 101% of the aggregate principal amount of 8.5% Notes repurchased plus accrued and unpaid interest on the 8.5% Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to such 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 describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 10.16 and that all 8.5% Notes tendered will be accepted for payment;

(2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) that any 8.5% Note not tendered will continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all 8.5% Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any 8.5% Notes purchased pursuant to a Change of Control Offer will be required to surrender the 8.5% Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the 8.5% Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Company, the depositary or Paying Agent, as the case may be, receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a

telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of 8.5% Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the 8.5% Notes purchased; and

(7) that Holders whose 8.5% Notes are being purchased only in part will be issued new 8.5% Notes equal in principal amount to the unpurchased portion of the 8.5% Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the 8.5% Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 10.16 (or compliance with this Section 10.16 would constitute a violation of any such laws or regulations), the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 10.16 by virtue of such compliance.

(b) No later than 11:00 a.m., New York City time, on the Change of Control Payment Date, the Company will, to the extent lawful:

(1) accept for payment all 8.5% Notes or portions of 8.5% Notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the depositary or Paying Agent, as the case may be, an amount equal to the Change of Control Payment in respect of all 8.5% Notes or portions of 8.5% Notes properly tendered and not properly withdrawn; and

(3) deliver or cause to be delivered to the Trustee the 8.5% Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of 8.5% Notes or portions of 8.5% Notes being purchased by the Company.

The Company, the depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Change of Control Payment Date) mail or deliver to each Holder of 8.5% Notes properly tendered and accepted by the Company for purchase the Change of Control Payment for such 8.5% Notes, and the Company will promptly issue, and the Trustee, upon written request from the Company, will promptly authenticate and mail or deliver (or cause to be transferred by book entry) to each Holder a new 8.5% Note equal in principal amount to any unpurchased portion of the 8.5% Notes surrendered; provided that each new 8.5% Note will be in a principal amount of $1,000 or an integral multiple of $1,000. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Notwithstanding anything to the contrary in this Section 10.16, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with

the requirements set forth in this Section 10.16 of this Indenture and purchases all 8.5% Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 11.4 of this Indenture, unless and until there is a default in payment of the applicable Redemption Price.

(d) Prior to complying with any of the provisions of this Section 10.16, but in any event no later than the Change of Control Purchase Date, the Company (or any Guarantor) must either repay all of its other outstanding senior Indebtedness or obtain the requisite consents, if any, under all agreements governing such senior Indebtedness to the extent necessary to permit the repurchase of 8.5% Notes required by this Section 10.16.

Section 10.17. Additional Guarantors.

If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary after the Issue Date, then the Company shall cause that newly acquired or created Domestic Restricted Subsidiary to become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit B to the First Supplemental Indenture and delivering an Opinion of Counsel satisfactory to the Trustee within ten Business Days of the date on which it was acquired or created to the effect that such supplemental indenture has been duly authorized, executed and delivered by that Domestic Restricted Subsidiary and constitutes a valid and binding agreement of that Domestic Restricted Subsidiary, enforceable in accordance with its terms (subject to customary exceptions); provided that any Domestic Restricted Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it ceases to be an Immaterial Subsidiary.

Section 10.18. Sale-and-Leaseback Transactions.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any sale-and-leaseback transaction; provided, however, that the Company or any Restricted Subsidiary, as applicable, may enter into a sale-and-leaseback transaction if:

(1) the Company or such Restricted Subsidiary could have

(a) incurred Indebtedness in an amount equal to the Attributable Indebtedness relating to such sale-and-leaseback transaction pursuant to the Consolidated Interest Coverage Ratio test set forth in Section 10.10(a) of this Indenture and

(b) incurred a Lien to secure such Indebtedness pursuant to Section 10.13 of this Indenture;

(2) the gross cash proceeds of such sale-and-leaseback transaction are at least equal to the fair market value of the property that is the subject of such sale-and-leaseback transaction; and

(3) the disposition of assets in such sale-and-leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 10.14 of this Indenture.

Section 10.19. Line of Business.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, engage in any business or activity other than the Principal Business, except to the extent as would not be material to the Company and its Subsidiaries considered as one enterprise.

Section 10.20. Covenant Suspension.

During any period beginning on a date when the 8.5% Notes have an Investment Grade Rating and no Default has occurred and is continuing and continuing until the next subsequent Reinstatement Date (as defined in Section 10.20(b)), the Company and the Restricted Subsidiaries will not be subject to Sections 10.10, 10.11, 10.12, 10.14, 10.15, 10.16, 10.18 and 8.01(a)(4) (collectively, the “Suspended Covenants”); provided that if the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding portion of this sentence and, at any subsequent date the Notes do not have an Investment Grade Rating, then the Company and its Restricted Subsidiaries will on such date immediately become again subject to the Suspended Covenants, subject to the terms, conditions and obligations set forth in the Indenture (each such date of reinstatement being referred to as a “Reinstatement Date”). During any period that the Suspended Covenants have been suspended pursuant to the preceding sentence, the Board of Directors may not designate any of the Restricted Subsidiaries of the Company as Unrestricted Subsidiaries pursuant the definition of “Unrestricted Subsidiary.” Compliance with the Suspended Covenants with respect to Restricted Payments made after the Reinstatement Date will be calculated in accordance with the terms of the covenant in Section 10.11 as though such covenant had been in effect during the entire period of time from which the Notes are issued; provided, however, no actions taken by the Company or any Restricted Subsidiary during such period will constitute a Default or Event of Default.

SECTION 7. Amendments to Article Eleven of the Original Indenture.

(a) The first paragraph of Section 11.3 of the Original Indenture is amended with respect to the 8.5% Notes in its entirety to read as follows:

If less than all of the 8.5% Notes are to be redeemed at any time, the particular 8.5% Notes to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, form the Outstanding Securities of such series not previously called for redemption, (a) in compliance with the requirements of the principal national securities exchange on which the 8.5% Notes are listed, if the 8.5% Notes are listed on any national securities exchange, or (b) if the 8.5% Notes are not listed on any national securities exchange, on a pro rata basis or on as nearly a pro rata basis as is practicable, subject to the applicable procedures of the Depository, unless such method is otherwise prohibited. No 8.5% Notes of $1,000 or less principal amount will be redeemed in part.

(b) Section 11.4 of the Original Indenture is amended with respect to the 8.5% Notes to add the following sentence thereto:

Notices of redemption may not be conditional.

By 11:00 a.m., New York City time, on the Redemption Date for any 8.5% Notes, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money, in immediately available funds, sufficient to pay the Redemption Price of and accrued interest on (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date that is on or prior to the Redemption Date) such Securities or any portions thereof that are to be redeemed on that date.

(d) Article Eleven of the Original Indenture is amended with respect to the 8.5% Notes by adding Sections 11.8 and 11.9 as follows:

(1) at least 65% of the aggregate principal amount of 8.5% Notes originally issued under this Indenture remains outstanding immediately after the occurrence of such redemption (excluding 8.5% Notes held by the Company or its Affiliates); and

(2) the redemption occurs within 120 days of the date of the closing of each such Equity Offering.

(b) On or after September 15, 2012, the Company may redeem all or part of the 8.5% Notes at the following Redemption Prices (expressed as percentages of the principal amount), plus accrued and unpaid interest to the applicable Redemption Date (subject to the rights of Holders on the relevant record date to receive interest on an Interest Payment Date that is on or prior to the Redemption Date), if redeemed during the twelve-month period beginning on September 15 of the year indicated below:


Year	Percentage
2012	104.250	%
2013	102.125	%
2014 and thereafter	100.000	%

(c) At any time prior to September 15, 2012, the Company may redeem the 8.5% Notes, in whole or in part, at the Make-Whole Price, plus accrued and unpaid interest to the Redemption Date (subject to the rights of Holders on the relevant record date to receive interest on an Interest Payment Date that is on or prior to the Redemption Date).

(d) Any redemption pursuant to this Section 11.8 shall be made pursuant to the provisions of Sections 11.2 through 11.7 of the Indenture.

(e) Except pursuant to the preceding paragraphs (a), (b) and (c) of this Section 11.8, the 8.5% Notes will not be redeemable at the Company’s option prior to September 15, 2012.

Section 11.9. No Mandatory Redemption or Sinking Fund.

There will be no mandatory redemption or sinking fund payments for the 8.5% Notes.

SECTION 8. Amendments to Article Thirteen of the Original Indenture.

(a) Section 13.2 of the Original Indenture is superseded with respect to the 8.5% Notes by the following provisions:

ARTICLE THIRTEEN

DEFEASANCE

Section 13.1. Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officer’s Certificate, elect to have either Section 13.2 or 13.3 of this Indenture be applied to all outstanding 8.5% Notes upon compliance with the conditions set forth below in this Article Thirteen.

Section 13.2. Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 13.1 of this Indenture of the option applicable to this Section 13.2, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 13.4 of this Indenture, be deemed to have been discharged from their obligations with respect to all Outstanding 8.5% Notes (including the Subsidiary Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the Outstanding 8.5% Notes (including the Subsidiary Guarantees), which will thereafter be deemed to be “Outstanding” only for the purposes of Section 13.5 of this Indenture and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their

other obligations under such 8.5% Notes, the Subsidiary Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of Outstanding 8.5% Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such 8.5% Notes when such payments are due from the trust referred to in Section 13.4 of this Indenture;

(2) the Company’s obligations with respect to such 8.5% Notes under Sections 3.4, 3.5, 3.6, 10.2 and 10.3 of this Indenture;

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and

(4) this Article Thirteen.

Subject to compliance with this Article Thirteen, the Company may exercise its option under this Section 13.2 notwithstanding the prior exercise of its option under Section 13.3 of this Indenture.

Section 13.3. Covenant Defeasance.

Upon the Company’s exercise under Section 13.1 of this Indenture of the option applicable to this Section 13.3, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 13.4 of this Indenture, be released from, each of their obligations under the covenants contained in Sections 10.8 through 10.19, inclusive, of this Indenture and clause (4) of Section 8.1(a) of this Indenture with respect to the Outstanding 8.5% Notes on and after the date the conditions set forth in Section 13.4 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the 8.5% Notes will thereafter be deemed not “Outstanding” for the purposes of any direction, waiver, consent or declaration or other Act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “Outstanding” for all other purposes hereunder (it being understood that such 8.5% Notes will not be deemed Outstanding for accounting purposes to the extent permitted by GAAP). For this purpose, Covenant Defeasance means that, with respect to the Outstanding 8.5% Notes and Subsidiary Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default with respect to the 8.5% Notes under Section 5.1 of this Indenture, but, except as specified above, the remainder of this Indenture and such 8.5% Notes and Subsidiary Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 13.1 of this Indenture of the option applicable to this Section 13.3, subject to the satisfaction of the conditions set forth in Section 13.4 of this Indenture, Sections 5.1(3) through 5.1(6), inclusive, of this Indenture and, only with respect to Subsidiaries of the Company, Sections 5.1(8) and 5.1(9), will not constitute Events of Default with respect to the 8.5% Notes.

Section 13.4. Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 13.2 or 13.3 of this Indenture:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the 8.5% Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, or interest and premium, if any, on the Outstanding 8.5% Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Company must specify whether the 8.5% Notes are being defeased to such stated date for payment or to a particular Redemption Date;

(2) in the case of an election under Section 13.2 of this Indenture, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(B) since the Issue Date, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall Confirm that, the Holders of the Outstanding 8.5% Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of an election under Section 13.3 of this Indenture, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the Outstanding 8.5% Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default with respect to the 8.5% Notes shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Company must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of 8.5% Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others;

(7) the Company must deliver to the Trustee an Officer’s Certificate, stating that all conditions precedent set forth in clauses (1) through (6) of this Section 13.4 have been complied with; and

(8) the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent set forth in clauses (2), (3) and (5) of this Section 13.4 have been complied with; provided that the Opinion of Counsel with respect to clause (5) of this Section 13.4 may be to the knowledge of such counsel.

Section 13.5. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

(a) Subject to Section 13.6 of this Indenture, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 13.5, the “Trustee”) pursuant to Section 13.4 of this Indenture in respect of the Outstanding 8.5% Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such 8.5% Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent), to the Holders of such 8.5% Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

(b) The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 13.4 of this Indenture or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding 8.5% Notes.

Section 13.6. Repayment to Company.

(a) Notwithstanding anything in this Article Thirteen to the contrary, the Trustee and any Paying Agent will deliver or pay to the Company from time to time upon Company Request any money or Government Securities held by them as provided in Section 13.4 of this Indenture which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 13.4(1) of this Indenture), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

(b) The provisions of the last paragraph of Section 10.3 shall apply to any money held by the Trustee or any Paying Agent under this Article Thirteen that remains unclaimed for one year after the Maturity of the 8.5% Notes.

Section 13.7. Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or Government Securities in accordance with Section 13.2 or 13.3 of this Indenture, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the 8.5% Notes and the Subsidiary Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 13.2 or 13.3 of this Indenture until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 13.2 or 13.3 of this Indenture, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on, any 8.5% Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such 8.5% Notes to receive such payment from the money held by the Trustee or Paying Agent.

SECTION 9. Amendments to Article Fourteen of the Original Indenture.

(a) Article Fourteen of the Original Indenture is superseded with respect to the 8.5% Notes by the following provisions:

ARTICLE FOURTEEN

SUBSIDIARY GUARANTEES

Section 14.1. Subsidiary Guarantees.

(a) Subject to this Article Fourteen, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a 8.5% Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the 8.5% Notes or the obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium, if any, and interest on, the 8.5% Notes will be promptly paid in full when due, whether at final maturity, by acceleration, redemption or otherwise, and interest on any overdue principal of, premium, if any, and interest on the 8.5% Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any 8.5% Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at final maturity, by acceleration, redemption or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are, to the extent permitted by applicable law, unconditional, irrespective of the validity, regularity or enforceability of the 8.5% Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the 8.5% Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. To the extent permitted by applicable law, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the 8.5% Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, to the extent permitted by applicable law, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the Maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five of this Indenture for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article Five of this Indenture, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee.

Section 14.2. Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of 8.5% Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention,

the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article Fourteen, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 14.3. Execution and Delivery of Subsidiary Guarantee Notation.

To evidence its Subsidiary Guarantee set forth in Section 14.1 of this Indenture, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form set forth in Exhibit A to the First Supplemental Indenture will be endorsed by an officer of such Guarantor on each 8.5% Note authenticated and delivered by the Trustee.

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 14.1 of this Indenture will remain in full force and effect notwithstanding any failure to endorse on each 8.5% Note a notation of such Subsidiary Guarantee.

If an officer of a Guarantor whose signature is on a notation of the Subsidiary Guarantee of such Guarantor no longer holds that office at the time the Trustee authenticates the 8.5% Note on which such notation is endorsed, the Subsidiary Guarantee will be valid nevertheless.

The delivery of any 8.5% Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors.

Section 14.4. Guarantors May Consolidate, etc., on Certain Terms.

Subject to the provisions of Section 14.5 of this Indenture, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person (other than the Company or a Restricted Subsidiary of the Company), whether or not affiliated with such Guarantor, unless:

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and

(2) either:

(a) the Person acquiring the assets in any such sale or disposition, or the Person formed by or surviving any such consolidation or merger, assumes all of the obligations of that Guarantor under this Indenture and its Subsidiary Guarantee pursuant to a supplemental indenture satisfactory to the Trustee, in which case such successor Person will succeed to and be substituted for that Guarantor with the same effect as if it had been named herein as a Guarantor and the Subsidiary Guarantee of that Guarantor will be released as contemplated by Section 14.5 hereof; or

(b) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including Section 10.14 of this Indenture.

Section 14.5. Releases.

(a) In the event of any sale or other disposition, including by way of merger, consolidation or otherwise, of all or substantially all of the assets or all of the Capital Stock of any Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, then such Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture, if: (1) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including Section 10.14, and (2) upon such release, the obligations of such Guarantor in respect of any and all other guarantees of Indebtedness of the Company or a Guarantor are similarly released.

(b) Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture.

(c) Upon Legal Defeasance in accordance with Article Thirteen of this Indenture or satisfaction and discharge of this Indenture in accordance with Article Four of this Indenture, each Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture.

Upon request by the Company, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Indenture.

Section 14.6. Successors and Assigns.

This Article Fourteen shall be binding upon each Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the 8.5% Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 14.7. Contribution.

Each Guarantor that makes a payment under its Subsidiary Guarantee shall be entitled upon payment in full of all guaranteed obligations to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective Adjusted Net Assets of all the Guarantors at the time of such payment.

SECTION 10. Governing Law.

This First Supplemental Indenture and the 8.5% Notes shall be governed by and construed in accordance with the laws of the State of New York.

SECTION 11. Counterparts.

This First Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original but such counterparts shall together constitute but one and the same instrument.

SECTION 12. Supplemental Indenture Controls.

In the event there is any conflict or inconsistency between the Original Indenture and this First Supplemental Indenture, the provisions of this First Supplemental Indenture shall control.

IN WITNESS WHEREOF, the parties hereto have caused this First Supplemental Indenture to be duly executed as of the day and year first above written.

[FORM OF THE REVERSE OF 8.5% NOTE]

FRONTIER OIL CORPORATION

8.5% Senior Note due 2016

Indenture; Limitations.

The Company issued the 8.5% Notes under the Indenture dated as of September 17, 2008 (the “Original Indenture”), as supplemented and amended by the First Supplemental Indenture dated as of September 17, 2008 (the Original Indenture as so supplemented and amended being hereinafter referred to as the “Indenture”), among the Company, the Guarantors named therein and ▇▇▇▇▇ Fargo Bank, National Association, as trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the 8.5% Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The 8.5% Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this 8.5% Note and the terms of the Indenture, the terms of the Indenture shall control.

The 8.5% Notes are senior obligations of the Company and the aggregate principal amount of the 8.5% Notes which may be issued, executed, authenticated, delivered and outstanding is unlimited (subject to Section 1 of the First Supplemental Indenture). The Company may, subject to Section 10.10 of the Indenture, issue Additional 8.5% Notes under the Indenture in either a limited or an unlimited aggregate principal amount. This 8.5% Note is one of the Original 8.5% Notes referred to in the Indenture issued in an aggregate principal amount of $200,000,000. The Additional 8.5% Notes may be issued as part of the same or a different series of Securities as the Original 8.5% Notes, but all such 8.5% Notes shall be treated as a single class under the Indenture.

Principal and Interest.

The Company will pay the principal of this 8.5% Note on September 15, 2016.

The Company promises to pay interest on the principal amount of this 8.5% Note on each March 15 and September 15 (each an “Interest Payment Date”), as set forth below, at the rate per annum shown above.

A-4

Interest will be payable semiannually in arrears (to the holders of record of the 8.5% Notes at the close of business on the March 1 or September 1 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing March 1, 2009.

Interest on the 8.5% Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from September 17, 2008, provided that, if there is no existing Default in the payment of interest and this 8.5% Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal or premium, if any, from time to time on demand at the rate borne by the 8.5% Notes plus 0.75% per annum, and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, to the extent lawful, from time to time on demand, at the rate borne by the 8.5% Notes plus 0.75% per annum.

Method of Payment.

The Company will pay interest (except Defaulted Interest) on the principal amount of the 8.5% Notes as provided above on each Interest Payment Date to the Persons who are Holders (as reflected in the Security Register at the close of business on the March 1 or September 1 immediately preceding the relevant Interest Payment Date), in each case, even if the 8.5% Note is canceled on registration of transfer, registration of exchange, redemption or repurchase after such record date and on or before the Interest Payment Date, provided that, with respect to the payment of principal, the Company will make payment to the Holder that surrenders this 8.5% Note to a Paying Agent on or after its Maturity.

The Company will pay all principal, premium, if any, and interest due on the 8.5% Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. With respect to 8.5% Notes represented by a Definitive Security, it may mail an interest check to the Holder’s registered address (as reflected in the Security Register); provided that payment by wire transfer of immediately available funds will be available to the Holder of any Definitive Securities in the aggregate principal amount of $1.0 million or more, upon request and upon providing wire transfer instructions to the Company or the Paying Agent. All payments in respect of 8.5% Notes represented by a Global Security will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. If a payment date is a date other than a Business Day at a Place of Payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period.

A-5

Paying Agent and Security Registrar.

Initially, the Trustee will act as Security Registrar in relation to the 8.5% Notes at its Corporate Trust Office in Dallas, Texas and as Paying Agent at its corporate trust office in The City and State of New York, which on the Issue Date is located at ▇▇ ▇▇▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇-▇▇▇▇.

Repurchase Upon a Change of Control.

Upon the occurrence of a Change of Control, each Holder of 8.5% Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 in principal amount or an integral multiple thereof) of such Holder’s 8.5% Notes pursuant to the Change of Control Offer as provided in, and subject to the terms of, Section 10.16 of the Indenture at a purchase price in cash equal to 101% of the aggregate principal amount of the 8.5% Notes repurchased, plus accrued and unpaid interest to the date of purchase (subject to the rights of Holders on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to such date of purchase).

Denominations; Transfer; Exchange.

The 8.5% Notes are in registered form without coupons in denominations of $1,000 of principal amount and multiples of $1,000 in excess thereof. A Holder may register the transfer of or exchange 8.5% Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges imposed on the transaction. The Security Registrar need not register the transfer of or exchange any 8.5% Notes selected for redemption (except in the case of a 8.5% Note redeemed in part, the portion of the 8.5% Note not to be redeemed). Also, it need not register the transfer of or exchange any 8.5% Notes for a period of 15 days before the day of the mailing of a notice of redemption of 8.5% Notes selected for redemption and ending on the day of such mailing.

Persons Deemed Owners.

A Holder shall be treated as the owner of a 8.5% Note for all purposes.

After that, Holders entitled to the money must look to the Company for payment, and all liability of the Trustee and any Paying Agent with respect to such money shall cease.
