The Notes shall be issued only in registered form. The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. Any notation of Subsidiary Guarantee shall be substantially in the form of Exhibit D hereto, and shall be notated on the Notes. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The Notes shall be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Series A Notes and the Series B Notes shall be considered collectively to be a single class for all purposes of this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Notwithstanding the foregoing, to the extent any provision of any Note or any notation of Subsidiary Guarantee conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling to the extent permitted by law.

- 21 -

(a) Global Notes. Series A Notes offered and sold to QIBs in reliance on Rule 144A shall be issued initially in the form of one or more 144A Global Notes, which shall be deposited on behalf of the purchasers of the Series A Notes represented thereby with the Note Custodian and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided. If beneficial interests in any such 144A Global Note or in any Regulation S Global Note are transferred to an Institutional Accredited Investor, then, for so long as the Applicable Procedures shall so permit, such beneficial interests shall be represented by an IAI Global Note having an initial principal amount equal to the aggregate amount of such beneficial interests, and such IAI Global Note shall be deposited on behalf of the beneficial owners of the Series A Notes represented thereby with the Note Custodian and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

Any Series A Notes offered and sold in reliance on Regulation S shall be issued initially in the form of a Regulation S Global Note, which shall be deposited on behalf of the purchasers of the Series A Notes represented thereby with the Note Custodian and registered in the name of the Depository or the nominee of the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

Each Global Note shall represent such of the outstanding Notes as shall be specified therein, and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, repurchases and transfers of interests. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee, as Registrar and Note Custodian, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

(b) Book-Entry Provisions. Participants shall have no rights either under this Indenture with respect to any Global Note held on their behalf by the Depository or by the Note Custodian as custodian for the Depository or under such Global Note, and the Depository (or its nominee, if the Depository is not the Holder) may be treated by the Company, the Trustee and any Agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any Agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in any Global Note.

Section 2.02 EXECUTION AND AUTHENTICATION.

One Officer shall sign the Notes for the Company by manual or facsimile signature. If the Company has a corporate seal, it may be reproduced on the Notes and, if so, it may be in facsimile form.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

A Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee. Such signature shall be conclusive evidence that the Note has been authenticated under this Indenture. The form of Trustee’s certificate of authentication to be borne by the Notes shall be substantially as set forth in Exhibit A hereto.

Each Note shall be dated the date of its authentication.

The Trustee shall authenticate (i) the Series A Notes for original issue on the Issue Date in the aggregate principal amount of $250,000,000 (the “Original Notes”), (ii) subject to compliance with Section 4.09 hereof, additional Series A Notes for original issue from time to time after the Issue Date in such principal amounts as may be set forth in a written order of the Company described in this sentence and (iii) the Series B Notes for original issue from time to time for issue only in exchange for a like principal amount of Series A Notes, in each case upon a written order of the Company signed by one Officer, which written order shall specify (a) the amount of Notes to be authenticated and the date of original issue thereof, (b) whether the Notes are Series A Notes or Series B Notes, and (c) the amount of Notes to be issued in global form or definitive form. The aggregate principal amount of Notes outstanding at any time may not exceed $250,000,000 plus such additional principal amounts as may be issued and authenticated pursuant to clause (ii) of this paragraph, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company, any Guarantor or an Affiliate of the Company.

The Company shall maintain an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (“Registrar”), and it shall maintain an office or agency in New York, New York, where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co registrars and one or more additional paying agents. The term “Registrar” includes any co registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not named in this

- 23 -

Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, and such agreement shall incorporate the TIA’s provisions of this Indenture that relate to such Agent. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints the Trustee to act as Registrar, Paying Agent and Note Custodian with respect to the Global Notes at its Corporate Trust Office.

Section 2.04 PAYING AGENT TO HOLD MONEY IN TRUST.

The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium or interest on, the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon the occurrence and during the continuance of any Event of Default described in clause (h) or (i) of Section 6.01 hereof, the Trustee shall serve as Paying Agent for the Notes.

Section 2.05 HOLDER LISTS.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA §312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA §312(a).

(c)(B) of the preceding paragraph; (c) 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; (d) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to the Company or any Wholly Owned Restricted Subsidiary of the Company; (e) so long as no Default or Event of Default has occurred and is continuing, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any employee of the Company or any of its Restricted Subsidiaries, provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $500,000 in any calendar year; (f) the acquisition of Equity Interests by the Company in connection with the exercise of stock options or stock appreciation rights by way of cashless exercise or in connection with the satisfaction of withholding tax obligations; (g) in connection with an acquisition by the Company or by any of its Restricted Subsidiaries, the return to the Company or any of its Restricted Subsidiaries of Equity Interests of the Company or any of its Restricted Subsidiaries constituting a portion of the purchase price consideration in settlement of indemnification claims; and (h) the purchase by the Company of fractional shares of Equity Interests arising out of stock dividends, splits or combinations or business combinations;.

The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default. For purposes of making such designation, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time of such designation (except to the extent they qualify as Permitted Investments), in an amount equal to the greater of (a) the net book value of such Investments at the time of such designation and (b) the fair market value of such Investments at the time of such designation. Such designation shall only be permitted if such Restricted Payments would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of “Unrestricted Subsidiary.”

The Board of Directors may also redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if such redesignation complies with the requirements described in the definition of “Unrestricted Subsidiary.” If the aggregate amount of all Restricted Payments calculated for purposes of the first paragraph of this Section 4.07 includes an Investment in an Unrestricted Subsidiary that subsequently becomes a Restricted Subsidiary pursuant to the terms of this paragraph, then the aggregate amount of such Restricted Payments shall be reduced by the lesser of (a) an amount equal to the fair market value of the Investments previously made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary at the time it becomes a Restricted Subsidiary and (b) the amount of such Investments.

Any designation or redesignation of a Subsidiary shall be evidenced to the Trustee by filing with the Trustee a Board Resolution giving effect to such action and evidencing the valuation of any Investment relating thereto (as determined in good faith by the Board of Directors) and an Officers’ Certificate certifying that such action complied with the terms of the definition of “Unrestricted Subsidiary” set forth in this Indenture and with this Section 4.07.

- 43 -

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,” and the results of such determination shall be evidenced by an Officers’ Certificate delivered to the Trustee. Not later than the date of making any Restricted Payment (other than a Restricted Payment permitted by clause (b), (c), (d), (f), (g) or (h) of the second full paragraph of this Section 4.07), the Company shall deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 4.07 were computed.

Section 4.08 DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to do any of the following: (a)(i) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or (ii) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; (b) make loans or advances to the Company or any of its Restricted Subsidiaries or (c) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries, except for such encumbrances or restrictions existing under or by reason of (1) the Credit Facility or Existing Indebtedness, each as in effect on the Issue Date, (2) this Indenture, the Notes and the Subsidiary Guarantees, (3) applicable law, (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 assets of any Person, other than the Person, or the assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, (5) by reason of customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices, (6) by reason of customary provisions restricting the transfer of copyrighted or patented materials consistent with industry practice, (7) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (c) above on the property so acquired, (8) customary provisions in bona fide contracts for the sale of properties or assets, (9) Permitted Refinancing Indebtedness with respect to any Indebtedness referred to in clauses (1), (2) and (4) above, provided that the restrictions referred to in this Section 4.08 that are 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 being refinanced or (10) provisions with respect to the disposition or distribution of assets in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business.

- 44 -

Section 4.09 INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF DISQUALIFIED STOCK.

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 (including, without limitation, Acquired 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 and its Restricted Subsidiaries may incur Indebtedness, and the Company may issue Disqualified Stock, in each case 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 at the time such additional Indebtedness is incurred or such Disqualified Stock is issued (such time being called the “Incurrence Time”), in each case as 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 issued or incurred, as the case may be, at the beginning of such four-quarter period.

The foregoing provisions shall not apply to the incurrence by the Company or any of its Restricted Subsidiaries of any of the following Indebtedness:

(a) Indebtedness under the Credit Facility in an aggregate principal amount at any one time outstanding not to exceed the greater of (1) $250,000,000 and (2) 20% of the Company’s Consolidated Net Tangible Assets determined as of the end of the Company’s most recently completed fiscal quarter for which internal financial statements are available;

(b) Existing Indebtedness;

(d) Indebtedness represented by the Original Notes, any Series B Notes issued in exchange for Series A Notes pursuant to an Exchange Offer or the Subsidiary Guarantees;

(e) intercompany Indebtedness between or among the Company and any of its Wholly Owned Restricted Subsidiaries, provided that any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Wholly Owned Restricted Subsidiary of the Company, or any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Wholly Owned Restricted Subsidiary of the Company, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, as of the date of such issuance, sale or other transfer that is not permitted by this clause (e);

(f) Indebtedness in respect of bid, performance or surety bonds issued for the account of the Company or any Restricted Subsidiary thereof in the ordinary course of business, including guarantees or obligations of the Company or any Restricted Subsidiary thereof with respect to letters of credit supporting such bid, performance or surety obligations (in each case other than for an obligation for money borrowed);

- 45 -

(g) the guarantee by the Company of Indebtedness of any of its Restricted Subsidiaries or by any Restricted Subsidiary of Indebtedness of the Company or another Restricted Subsidiary, in each case, that was permitted to be incurred by another provision of this Section 4.09;

(h) Permitted Refinancing Indebtedness incurred in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness incurred pursuant to the first paragraph and clause (b), (d) or (h) of the second paragraph of this Section 4.09; and

(i) any additional Indebtedness in an aggregate principal amount not in excess of $25,000,000 at any one time outstanding.

The Company shall not, and shall not permit any Guarantor to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or of such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Notes or the Subsidiary Guarantee of such Guarantor, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Company or of such Guarantor, as the case may be; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Indebtedness described in clauses (a) through (i) of the second paragraph, or is entitled to be incurred pursuant to the first paragraph, of this Section 4.09, the Company shall be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09, and such item of Indebtedness will be treated as having been incurred pursuant to such category.

Section 4.10 ASSET SALES.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale (excluding for this purpose an Event of Loss) unless (a) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in accordance with the definition of such term, the results of which determination shall be set forth in an Officers’ Certificate delivered to the Trustee) of the properties, assets, rights or Equity Interests issued or sold or otherwise disposed of and (b) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents; provided, however, that the amount of (i) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of

- 46 -

the Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets, properties, rights or Equity Interests pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability, (ii) Liquid Securities and (iii) any securities, notes or other obligations received by the Company or such Restricted Subsidiary from such transferee that are converted within 180 days by the Company or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion) shall each be deemed to be Cash Equivalents for purposes of this Section 4.10.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale (including, without limitation, any Event of Loss), the Company or any such Restricted Subsidiary may apply such Net Proceeds to (a) permanently repay all or any portion of the principal of any secured Indebtedness (to the extent of the fair value of the assets collateralizing such Indebtedness, as determined by the Board of Directors) or (b) acquire (including by way of a purchase of assets or stock, merger, consolidation or otherwise) Productive Assets, provided that if the Company or such Restricted Subsidiary enters into a binding agreement to acquire such Productive Assets within such 365-day period, but the consummation of the transactions under such agreement has not occurred within such 365-day period, and the agreement has not been terminated, then the 365-day period will be extended to 18 months to permit such consummation; provided further, however, if such consummation does not occur, or such agreement is terminated within such 18-month period, then the Company may apply, or cause such Restricted Subsidiary to apply, within 90 days after the end of the 18-month period or the effective date of such termination, whichever is earlier, such Net Proceeds as provided in clauses (a) and (b) of this paragraph. Pending the final application of any such Net Proceeds, the Company or any such Restricted Subsidiary may temporarily reduce outstanding revolving credit borrowings, including borrowings under the Credit Facility, or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (a) and (b) of this paragraph shall be deemed to constitute “Excess Proceeds.”

Within 30 days of each date on which the aggregate amount of Excess Proceeds exceeds $20,000,000, the Company shall commence an Asset Sale Offer pursuant to Section 3.09 hereof to purchase the maximum principal amount of Notes that may be purchased out of Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon, to the date of purchase, in accordance with the procedures set forth in Section 3.09 hereof; provided, however, that, if the Company is required to apply such Excess Proceeds to purchase, or to offer to purchase, any Pari Passu Indebtedness, the Company shall only be required to offer to purchase the maximum principal amount of 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 Notes outstanding and the denominator of which is the aggregate principal amount of Notes outstanding plus the aggregate principal amount of Pari Passu Indebtedness outstanding. To the extent that the aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is less than the amount that the Company is required to purchase, the Company may use any remaining Excess Proceeds for general corporate purposes in any manner not prohibited by this Indenture. If the aggregate principal amount of Notes surrendered by Holders

- 47 -

thereof exceeds the amount that the Company is required to purchase, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, shall be purchased). Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero.

The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or suffer to exist any agreement (other than any agreement governing the Credit Facility) that would place any restriction of any kind (other than pursuant to law or regulation) on the ability of the Company to make an Asset Sale Offer.

Section 4.11 TRANSACTIONS WITH AFFILIATES.

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 (each of the foregoing, an “Affiliate Transaction”), unless (a) 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 (b) the Company delivers to the Trustee (i) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10,000,000, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (a) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors and (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20,000,000, 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, provided that such opinion will not be required with respect to any Affiliate Transaction or series of related Affiliate Transactions involving either (i) shipyard contracts that are awarded following a competitive bidding process and approved by a majority of the disinterested members of the Board of Directors or (ii) an Affiliate in which an unrelated third person owns Voting Stock in excess of that owned by the Company or any of its Restricted Subsidiaries; provided, however, that the following shall be deemed not to be Affiliate Transactions: (A) any employment agreement or other employee compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business of the Company or such Restricted Subsidiary; (B) transactions between or among the Company and its Restricted Subsidiaries; (C) Permitted Investments and Restricted Payments that are permitted by the provisions of Section 4.07 of this Indenture; (D) loans or advances to officers, directors and employees of the Company or any of its Restricted Subsidiaries made in the ordinary course of business and consistent with past practices of the Company and its Restricted Subsidiaries in an aggregate amount not to exceed $500,000 outstanding at any one time;

- 48 -

(E) indemnities of officers, directors and employees of the Company or any of its Restricted Subsidiaries permitted by bylaw or statutory provisions; (F) maintenance in the ordinary course of business of customary benefit programs or arrangements for officers, directors and employees of the Company or any Restricted Subsidiary, including without limitation vacation plans, health and life insurance plans, deferred compensation plans, retirement or savings plans and similar plans; (G) registration rights or similar agreements with officers, directors or significant shareholders of the Company or any Restricted Subsidiary; (H) issuance of Equity Interests (other than Disqualified Stock) by the Company; and (I) the payment of reasonable and customary regular fees to directors of the Company or any of its Restricted Subsidiaries who are not employees of the Company or any Affiliate.

Section 4.12 LIENS.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or assume any Lien on any property or asset owned on the Issue Date or thereafter acquired, or any income or profits therefrom, except Permitted Liens, to secure (a) any Indebtedness of the Company, unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured, until such time as such Indebtedness is no longer secured by a Lien (other than Permitted Liens) or (b) any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, its Subsidiary Guarantee is equally and ratably secured, until such time as such Indebtedness is no longer secured by a Lien (other than Permitted Liens); provided, however, that if such Indebtedness is expressly subordinated to the Notes or the Subsidiary Guarantees, the Lien securing such Indebtedness shall be subordinated and junior to the Lien securing the Notes or the Subsidiary Guarantees, as the case may be, with the same relative priority as such Indebtedness has with respect to the Notes or the Subsidiary Guarantees.

Section 4.13 ADDITIONAL SUBSIDIARY GUARANTEES.

If the Company or any of its Restricted Subsidiaries shall, after the Issue Date, acquire or create another Significant Subsidiary or if any other Restricted Subsidiary shall become such, then such Significant Subsidiary shall become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit E hereto and delivering it to the Trustee, together with a notation of Subsidiary Guarantee, an Opinion of Counsel and an Officers’ Certificate, in accordance with the terms of Section 10.02 of this Indenture; provided, however, that this requirement shall not apply to a Significant Subsidiary that is also a Foreign Subsidiary. If, after the Issue Date, any Restricted Subsidiary of the Company (including a Foreign Subsidiary) that is not already a Guarantor shall guarantee any other Indebtedness of the Company or any Indebtedness of a Domestic Subsidiary, then that Subsidiary shall become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit E hereto and delivering it to the Trustee, together with a notation of Subsidiary Guarantee, an Opinion of Counsel and an Officers’ Certificate, in accordance with the terms of such Section 10.02, within ten Business Days of the date on which it guaranteed such Indebtedness. Notwithstanding the preceding, any Subsidiary Guarantee of a Restricted Subsidiary (other than a Significant Subsidiary) shall be unconditionally released, as provided in Section 10.05 hereof, upon the release or discharge of its guarantee of all other Indebtedness of the Company or any of its Domestic Subsidiaries, except a release or discharge by, or as a result of payment under, such guarantee.

- 49 -

Section 4.14 CORPORATE EXISTENCE.

Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, and, subject to Article 10 hereof, the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary; provided, however, that the Company shall not be required to preserve the existence of any of its Restricted Subsidiaries, if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole.

Section 4.15 OFFER TO PURCHASE UPON CHANGE OF CONTROL.

(a) Upon the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to purchase all or any portion (equal to minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof) of each Holder’s Notes, at a purchase price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of purchase (the “Change of Control Payment”), subject to the right of Noteholders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to such date of purchase. Within 30 days following a Change of Control, the Company shall give notice to each Holder and the Trustee stating: (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered and not withdrawn will be accepted for payment; (2) the purchase price and the purchase date, which shall be no earlier than 30 days but no later than 60 days from the date such notice is given (the “Change of Control Payment Date”); (3) that any Note not tendered will continue to accrue interest; (4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date; (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed and such customary documents as the Company may reasonably request, to the 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 Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to a minimum of $2,000 in principal amount. If any of the Notes subject to a Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to repurchases. Further, the Company shall

- 50 -

comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of 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 relating to the Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Section 4.15 by virtue thereof.

(b) At or before 11:00 a.m., New York time, on the Change of Control Payment Date, the Company shall, to the extent lawful, (a) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered and (c) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly deliver to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a minimum principal amount of $2,000. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) The Change of Control provisions described above shall be applicable whether or nor any other provisions of this Indenture are applicable.

(d) The Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.16 ISSUANCES AND SALES OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES.

The Company (i) shall not, and shall not permit any Restricted Subsidiary of the Company to, transfer, convey, sell or otherwise dispose of any Capital Stock of any Restricted Subsidiary of the Company to any Person (other than the Company or a Wholly Owned Restricted Subsidiary of the Company), unless (a) such transfer, conveyance, sale or other disposition is of all the Capital Stock of such Restricted Subsidiary and (b) the Net Proceeds from such transfer, conveyance, sale or other disposition are applied in accordance with Section 4.10 hereof, and (ii) shall not permit any Restricted Subsidiary of the Company to issue any of its Equity Interests to any Person other than to the Company or a Wholly Owned Restricted Subsidiary of the Company, except, in the case of both clauses (i) and (ii) above, with respect to (1) dispositions or issuances by a Wholly Owned Restricted Subsidiary of the Company as contemplated in clauses (a) and (b) of the definition of “Wholly Owned Restricted Subsidiary” or (2) other dispositions or issuances of Capital Stock of a Restricted Subsidiary of the Company, provided that, after giving pro forma effect thereto, the Investment of the Company and its Restricted Subsidiaries in all Restricted Subsidiaries that are not Wholly Owned

- 51 -

Restricted Subsidiaries of the Company, determined on a consolidated basis in accordance with GAAP, does not exceed 25% of Consolidated Net Tangible Assets of the Company. For purposes of this Section 4.16, the creation or perfection of a Lien on any Capital Stock of a Restricted Subsidiary of the Company to secure any Indebtedness of the Company or any of its Restricted Subsidiaries shall not be deemed to be a disposition of such Capital Stock; provided, however, any sale by the secured party of such Capital Stock following foreclosure of its Lien shall be subject to this Section 4.16.

Section 4.17 SALE-AND-LEASEBACK TRANSACTIONS.

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 (i) 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 the first paragraph of Section 4.09 hereof, provided, however, that this clause (2) shall no longer be effective if the Terminated Covenants shall have terminated in accordance with Section 4.19 hereof, and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.12 hereof, (ii) the gross cash proceeds of such sale-and-leaseback transaction are at least equal to the fair market value (as determined in accordance with the definition of such term, the results of which determination shall be set forth in an Officers’ Certificate delivered to the Trustee) of the properties or assets that are the subject of such sale-and-leaseback transaction and (iii) the transfer of such properties or assets in such sale-and-leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof.

Section 4.18 NO INDUCEMENTS.

The Company shall not, and the Company shall not permit any of its Subsidiaries, either directly or indirectly, to pay (or cause to be paid) any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver, amendment or supplement of any terms or provisions of this Indenture or the Notes, unless such consideration is offered to be paid (or agreed to be paid) to all Holders which so consent, waive or agree to amend or supplement in the time frame set forth on solicitation documents relating to such consent, waiver, agreement or supplement.

Section 4.19 COVENANT TERMINATION.

(a) Once the Notes have achieved an Investment Grade Rating and no Default has occurred and is continuing under this Indenture, the Company and its Restricted Subsidiaries shall no longer be subject to Sections 3.09, 4.07, 4.08, 4.09, 4.10, 4.11, 4.15, 4.16 and 4.21 of this Indenture (collectively, the “Terminated Covenants”) and any provision of the Notes inconsistent with the elimination of the Terminated Covenants; provided, however, the Company and its Restricted Subsidiaries shall remain subject to Sections 4.01-4.06, 4.12, 4.13, 4.14, 4.17 (except to the extent set forth therein), 4.18, 4.20 and 5.01 (except to the extent set forth therein) of this Indenture. The Company shall deliver promptly to the Trustee an Officers’ Certificate notifying it of such occurrence.

- 52 -

(b) After termination of the Terminated Covenants, for purposes of complying with Section 4.12, the Liens described in clauses (a) and (m) of the definition of “Permitted Liens” shall be Permitted Liens only to the extent those Liens secure Indebtedness not exceeding, at the time of determination, 10% of the Consolidated Net Tangible Assets of the Company.

Section 4.20 ENFORCEABILITY OF JUDGMENTS; INDEMNIFICATION FOR FOREIGN CURRENCY JUDGMENTS.

The obligations of the Company to any Holder or the Trustee shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than United States dollars (the “Agreement Currency”), be discharged only to the extent that on the day following receipt by such Holder or the Trustee, as the case may be, of any amount in the Judgment Currency, such Holder or the Trustee may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the amount originally to be paid to such Holder or the Trustee, as the case may be, in the Agreement Currency, the Company agrees, as a separate obligation and notwithstanding such judgment, to pay to such Holder or the Trustee, as the case may be, the difference, and if the amount of the Agreement Currency so purchased exceeds the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, shall pay to or for the account of the Company such excess, provided that such Holder or the Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default has occurred and is continuing, in which case such excess may be applied by such Holder or the Trustee, as the case may be, to such obligations.

DEFAULTS AND REMEDIES

Section 6.01 EVENTS OF DEFAULT.

An “Event of Default” occurs if:

(a) the Company defaults in the payment when due of interest (including any Additional Interest) on the Notes, and such default continues for a period of 30 days;

(b) the Company defaults in the payment when due of principal of or premium, if any, on the Notes;

(d) the Company fails to observe or perform any other then applicable covenant or other agreement in this Indenture or the Notes for 60 days after it receives written notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding of such failure;

(e) a default occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which default (i) is caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness, including any extension thereof (a “Payment Default”) or (ii) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates at least $10,000,000; and provided, further, that if such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

(f) a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company or any of its Restricted Subsidiaries and such judgment or judgments are not paid or discharged for a period (during which execution shall not be effectively stayed) of 60 days, provided that the aggregate of all such undischarged judgments exceeds $10,000,000;

(g) the failure of any Guarantor to perform any covenant set forth in its Subsidiary Guarantee or the repudiation by any Guarantor of its obligations under its Subsidiary Guarantee or the unenforceability of any Subsidiary Guarantee for any reason other than as provided in this Indenture;

- 55 -

(h) the Company or any Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law:

(i) commences a voluntary case,

(ii) consents to the entry of an order for relief against it in an involuntary case,

(iii) consents to the appointment of a Custodian of it or for all or substantially all of its property,

(iii) orders the liquidation of the Company or any Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days.

Section 6.02 ACCELERATION.

If any Event of Default occurs and is continuing, the Trustee may, by written notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes may, by written notice to the Company and the Trustee, and the Trustee shall, upon the request of such Holders, declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (h) or (i) of Section 6.01 hereof occurs with respect to the Company, all outstanding Notes shall be due and payable immediately without further action or notice. The Holders of a majority in principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium, if any, that has become due solely because of such acceleration) have been cured or waived.

- 56 -

If an Event of Default occurs by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an equivalent premium shall also become and be immediately due and payable, to the extent permitted by law, anything in this Indenture or in the Notes to the contrary notwithstanding.

Section 6.03 OTHER REMEDIES.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, or interest on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 WAIVER OF PAST DEFAULTS.

Holders of a majority in principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on, the Notes (including in connection with an offer to purchase). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 CONTROL BY MAJORITY.

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

Section 6.06 LIMITATION ON SUITS.

A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if:

(a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default;

- 57 -

(b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of security or indemnity; and

(e) during such 60 day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, if any, and interest on, the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 COLLECTION SUIT BY TRUSTEE.

If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and premium, if any, and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 TRUSTEE MAY FILE PROOFS OF CLAIM.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and

- 58 -

counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 PRIORITIES.

If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the Trustee’s reasonable costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and

Third: to the Company or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11 UNDERTAKING FOR COSTS.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any applicable bankruptcy law.

For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, and each Guarantor shall be deemed to have paid and discharged its Subsidiary Guarantee (which in each case shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.06 hereof and the other Sections of this Indenture referred to in (a) and (b) below) and to have satisfied all its other obligations under such Notes or Subsidiary Guarantee 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 shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, and premium, if any, and interest on, such Notes when such payments are due, (b) the Company’s obligations with respect to such Notes under Sections 2.03, 2.04, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and any Guarantor’s obligations in connection therewith and (d) this Article 8.

Section 8.03 COVENANT DEFEASANCE.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their respective obligations under the covenants contained in Article 4 (other than those in Sections 4.01, 4.02, 4.06, and 4.14) on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and any Guarantor may omit to comply with and shall 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 shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c), 6.01(e) and 6.01(f) hereof shall not constitute Events of Default.

- 69 -

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Securities deposited pursuant to Section 8.04 or 8.05 hereof 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 Notes.

Section 8.07 REPAYMENT TO COMPANY.

Subject to applicable escheat and abandoned property laws, any money or U.S. Government Securities deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or U.S. Government Securities, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in Investor’s Business Daily and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Nothing contained in this Section 8.07 shall be deemed to affect any obligation of the Trustee or any Paying Agent to search for lost Holders pursuant to Rule 17Ad 17 under the Exchange Act.

Section 8.08 REINSTATEMENT.

If the Trustee or a Paying Agent is unable to apply any dollars or U.S. Government Securities in accordance with Section 8.05 or 8.06 hereof, 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, the Notes and the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02, 8.03 or 8.05 hereof until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 8.05 or 8.06 hereof, as the case may be; provided, however, that, if the Company or any Guarantor makes any payment of principal of, or premium, if any, or interest on, any Note following the reinstatement of its obligations, then it shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Securities held by the Trustee or such Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 WITHOUT CONSENT OF HOLDERS OF NOTES.

Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note:

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

(b) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(d) to secure the Notes pursuant to the requirements of Section 4.12 or otherwise;

(e) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note, provided that any change to conform this Indenture to the Company’s final offering memorandum relating to the Series A Notes shall not be deemed to adversely affect such legal rights;

(f) to add or to release any Guarantor, in each case as provided in Article 10 hereof; or

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

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 9.06 hereof, the Trustee shall 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 shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 WITH CONSENT OF HOLDERS OF NOTES.

Except as provided below in this Section 9.02, the Company, the Guarantors and the Trustee may amend or supplement this Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or

- 71 -

Event of Default or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for the Notes).

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 Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of 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, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

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

(b) reduce the principal of or change the fixed maturity of any Note or alter any of the provisions with respect to the redemption or purchase of the Notes by the Company (except other than the provisions of Sections 3.09, 4.10 and 4.15 hereof);

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

(e) make any Note payable in money other than that stated in the Notes;

- 72 -

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or Events of Default or the rights of Holders of Notes to receive payments of principal of, or premium, if any, or interest on, the Notes (except as permitted in clause (g) below);

(g) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 4.10 and 4.15 hereof);

(h) make any change in the ranking of the Notes relative to other Indebtedness of the Company or in any Subsidiary Guarantee relative to other Indebtedness of the Guarantors, in either case in a manner adverse to the Holders of Notes; or

(i) make any change in the foregoing amendment, supplement and waiver provisions.

Section 9.03 COMPLIANCE WITH TRUST INDENTURE ACT.

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect.

Section 9.04 REVOCATION AND EFFECT OF CONSENTS.

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

Section 9.05 NOTATION ON OR EXCHANGE OF NOTES.

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

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

Section 9.06 TRUSTEE TO SIGN AMENDMENTS, ETC.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Company shall deliver to the Trustee and (subject to Section 7.01) the Trustee shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10

GUARANTEES OF NOTES

Section 10.01 SUBSIDIARY GUARANTEES.

Subject to Section 10.06 hereof, the Guarantors hereby, jointly and severally, unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes held thereby and the Obligations of the Company hereunder and thereunder, that: (a) the principal of, and premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and premium, if any, and interest (to the extent permitted by law) on, the Notes, and all other payment Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise. Failing payment when so 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. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the Obligations of the Company. The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder 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 (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, 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 covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, the Trustee or any Custodian in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to, and hereby waives, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of the Obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article 6

- 74 -

hereof, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

Section 10.02 EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEE.

To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee in substantially the form of Exhibit D hereto may be endorsed by manual or facsimile signature by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that the supplemental indenture to this Indenture referred to in the next succeeding paragraph shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

To the extent required by the provisions of Section 4.13 hereof, the Company shall cause each of its Restricted Subsidiaries to execute a notation of Subsidiary Guarantee in substantially the form of Exhibit D hereto. Such notation of Subsidiary Guarantee shall be accompanied by a supplemental indenture in substantially the form of Exhibit E hereto, along with the Opinion of Counsel and Officers’ Certificate required under Section 9.06 of this Indenture; provided, however, that any Subsidiary that has been properly designated as an Unrestricted Subsidiary in accordance with this Indenture need not execute a notation of Subsidiary Guarantee or supplemental indenture for so long as it continues to constitute an Unrestricted Subsidiary.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantees on behalf of the Guarantors. Each Guarantor hereby agrees that its Subsidiary Guarantee shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee.

If an Officer whose signature is on the notation of Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a notation of Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall be valid nevertheless.

Section 10.03 GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

(a) Except as set forth in Articles 4 and 5 hereof, nothing contained in this Indenture shall prohibit a merger between a Guarantor and another Guarantor or a merger between a Guarantor and the Company.

(b) No Guarantor shall consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person (other than the Company or another Guarantor), whether or not affiliated with such Guarantor, unless: (i) subject to the provisions of Section 10.04 hereof, the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor under the Notes and this Indenture, pursuant to a supplemental indenture in substantially the form of Exhibit E hereto, accompanied by a notation of its Subsidiary Guarantee as provided in such supplemental indenture; (ii) immediately

- 75 -

after giving effect to such transaction, no Default or Event of Default exists; (iii) such Guarantor, or any Person formed by or surviving any such consolidation or merger, would have a Consolidated Net Worth (immediately after giving effect to such transaction) equal to or greater than the Consolidated Net Worth of such Guarantor immediately preceding the transaction; and (iv) the Company, immediately after giving pro forma effect to such transaction as if such transaction had occurred at the beginning of the applicable four-quarter period, would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof.

(c) In the case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and substantially in the form of Exhibit E hereto, of the Subsidiary Guarantee and the due and punctual performance of all of the covenants of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Section 10.04 RELEASES FOLLOWING SALE OF GUARANTOR.

In the event of a sale or other disposition of all or substantially all of the properties or assets or all of the Capital Stock of any Guarantor, by way of merger, consolidation or otherwise, then such Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the Person acquiring the properties or assets (in the event of a sale or other disposition of all or substantially all of the properties or assets of such Guarantor) shall be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture; provided, however, that in the event such transaction constitutes an Asset Sale, the Net Proceeds from such sale or other disposition are treated in accordance with the provisions of Section 4.10 hereof. Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect of the foregoing, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Indenture. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of, and premium, if any, and interest on, the Notes and for the other Obligations of such Guarantor under this Indenture as provided in this Article 10.

Section 10.05 RELEASES FOLLOWING DESIGNATION AS AN UNRESTRICTED SUBSIDIARY.

In the event that (i) the Company designates a Guarantor to be an Unrestricted Subsidiary or (ii) the guarantee by a Guarantor (other than a Significant Subsidiary) of all other Indebtedness of the Company or any of its Domestic Subsidiaries is released or discharged, except by, or as a result of payment under, such guarantee, then such Guarantor shall be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture; provided, however, that, in the case of clause (i), such designation is conducted in accordance with this Indenture. Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect of the foregoing or following the occurrence of either Legal Defeasance or the satisfaction and discharge of this Indenture pursuant to Section 8.05 hereof, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Indenture.

- 76 -

Section 10.06 LIMITATION ON GUARANTOR LIABILITY.

Each Guarantor and, by its acceptance of Notes, each Holder, hereby confirm 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 any applicable bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state or foreign 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 under its Subsidiary Guarantee and this Article 10 shall be limited to the maximum amount as 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 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.07 “TRUSTEE” TO INCLUDE PAYING AGENT.

In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 10 in place of the Trustee.

7. PUT OPTION OF HOLDER.

(a) If there is a Change of Control, the Company shall be required to make an offer (a “Change of Control Offer”) to purchase all or any portion (equal to minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof) of each Holder’s Notes, at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall give notice to each Holder and the Trustee describing the transaction that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b) If the Company or a Restricted Subsidiary consummates any Asset Sales, within 30 days of each date on which the aggregate amount of Excess Proceeds exceeds $20,000,000, the Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in the Indenture; provided, however, that, if the Company is required to apply such Excess Proceeds to purchase, or to offer to purchase, any Pari Passu Indebtedness, the Company shall only be required to offer to purchase the maximum principal amount of 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 Notes outstanding and the denominator of which is the aggregate principal amount of Notes outstanding plus the aggregate principal amount of Pari Passu Indebtedness outstanding. To the extent that the aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is less than the amount that the Company is required to purchase, the Company may use any remaining Excess Proceeds for general corporate purposes in any manner not prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof exceeds the amount that the Company is required to purchase, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, shall be purchased). Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes.

8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and

A-7

transfer documents and the Company may require a Holder to pay any transfer taxes or similar governmental charges. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

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

11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation, to secure the Notes, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder (provided that any change to conform the Indenture to the final offering memorandum of the Company relating to the Series A Notes will not be deemed to adversely affect such legal rights), to add any additional Guarantor or to release any Guarantor from its Subsidiary Guarantee, in each case as provided in the Indenture, or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest, including Additional Interest, if any, on the Notes; (ii) default in payment when due of the principal of or premium, if any, on the Notes; (iii) failure by the Company to comply with any of the then applicable provisions of Section 3.09, 4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the Company for 60 days after it receives written notice to observe or perform any other then applicable covenant or other agreement in the Indenture or the Notes; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists or is created after the Issue Date, which default (a) is caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness, including any extension thereof (a “Payment Default”) or (b) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates at least $10,000,000, and provided, further, that if such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid within a period of 10 days from the continuation of such default beyond the

A-8

applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as said rescission does not conflict with any judgment or decree; (vi) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $10,000,000, which judgments are not paid, discharged or stayed for a period of 60 days; (vii) failure by any Guarantor to perform any covenant set forth in its Subsidiary Guarantee, or the repudiation by any Guarantor of its obligations under its Subsidiary Guarantee or the unenforceability of any Subsidiary Guarantee for any reason other than as provided in the Indenture; and (viii) certain events of bankruptcy or insolvency with respect to the Company or any Significant Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may, by written notice, declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to a payment obligation on the Notes) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

13. DEFEASANCE. The Notes are subject to legal and covenant defeasance upon the terms and conditions specified in Article 8 of the Indenture.

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

15. NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator, member, partner or shareholder or other owner of Capital Stock of the Company or any Guarantor, as such, shall not have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

We acknowledge that the Notes will bear legends substantially to the foregoing effect. We understand that the registrar will not be required to accept for registration of transfer any Notes, except upon presentation of evidence satisfactory to the Company that the foregoing restrictions on transfer have been complied with.

NOTATION OF SUBSIDIARY GUARANTEE

Subject to Section 10.06 of the Indenture, each Guarantor has jointly and severally, unconditionally guaranteed to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes and the Obligations of the Company under the Notes or under the Indenture, that: (a) the principal of, and premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on overdue principal of, and premium, if any, and interest (to the extent permitted by law) on, the Notes and all other payment Obligations of the Company to the Holders or the Trustee under the Indenture or under the Notes will be promptly paid in full and performed, all in accordance with the terms thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other payment Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise. Failing payment when so 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. An Event of Default under the Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors under the Indenture in the same manner and to the same extent as the Obligations of the Company. The Guarantors have agreed that their Obligations under the Indenture shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder 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. Each Guarantor further, to the extent permitted by law, has waived 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 covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and the Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any Note Custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor has agreed that it shall not be entitled to, and hereby has waived, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed under the Indenture. Each Guarantor further has agreed that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed under the Indenture may be accelerated as provided in Article 6 of the Indenture for the purposes of its Subsidiary Guarantee, notwithstanding

D-1

any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article 6 of the Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

The obligations of the Guarantors to the Holders and to the Trustee pursuant to the Subsidiary Guarantees and the Indenture are expressly set forth in Article 10 of the Indenture, and reference is hereby made to such Indenture for the precise terms of the Subsidiary Guarantees. The terms of Article 10 of the Indenture are incorporated herein by reference. The Subsidiary Guarantees are subject to release as and to the extent provided in Sections 10.04 and 10.05 of the Indenture.

Each Subsidiary Guarantee is a continuing guarantee and shall remain in full force and effect and shall be binding upon each Guarantor and its respective successors and assigns to the extent set forth in the Indenture until full and final payment of all of the Company’s Obligations under the Notes and the Indenture and shall inure 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 in the Indenture upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. Each Subsidiary Guarantee is a guarantee of payment and not a guarantee of collection.

For purposes hereof, each Guarantor’s liability under its Subsidiary Guarantee shall be limited in amount as provided in Section 10.06 of the Indenture.

Capitalized terms used herein have the same meanings given in the Indenture unless otherwise indicated.
