“Consolidated EBITDA” means, with respect to any Person, for any period, the sum (without duplication) of such Person’s: (i) Consolidated Net Income; and (ii) to the extent Consolidated Net Income has been reduced thereby: (A) all income taxes and foreign withholding taxes of such Person and its Restricted Subsidiaries paid or accrued in accordance with GAAP for such period; (B) Consolidated Interest Expense; (C) Consolidated Non-cash Charges less any non-cash items increasing Consolidated Net Income for such period (other than normal accruals in the ordinary course of business), all as determined on a consolidated basis for such Person and its Restricted Subsidiaries in accordance with GAAP; (D) facilities relocation costs, restructuring costs and acquisition integration costs and, in each case, related fees, including cash severance payments made in connection with acquisitions; and (E) any expenses or charges (other than depreciation or amortization expense) related to any Equity Offering, Permitted Investment, acquisition, disposition, recapitalization or the incurrence of Indebtedness permitted to be incurred by this Indenture (including a Refinancing thereof) (whether or not successful), including such fees, expenses or charges relating to the offering of the Notes.

Notwithstanding the preceding sentence: (x) amounts under clauses (ii)(A)-(D) relating to a Restricted Subsidiary of a Person will be added to Consolidated Net Income to compute Consolidated EBITDA of such Person only if (and in the same proportions) that net income (loss) of such Restricted Subsidiary was included in calculating Consolidated Net Income of such Person; and (y) to the extent the amounts set forth in clauses (ii)(A)-(D) are in excess of those necessary to offset a net loss of such Restricted Subsidiary, such excess will be added to

Consolidated Net Income to compute Consolidated EBITDA only if (and in the same proportion that) net income of such Restricted Subsidiary would be included in calculating Consolidated Net Income of such Person if such Restricted Subsidiary had generated net income instead of net loss.

“Consolidated Fixed Charge Coverage Ratio” means, with respect to any Person, the ratio of Consolidated EBITDA of such Person during the Four-Quarter Period to Consolidated Fixed Charges of such Person for the Four-Quarter Period. In addition to and without limitation of the foregoing, for purposes of this definition, “Consolidated EBITDA” and “Consolidated Fixed Charges” shall be calculated after giving effect on a pro forma basis for the period of such calculation to: (i) the incurrence or repayment of any Indebtedness or the issuance of any Designated Preferred Stock of such Person or any of its Restricted Subsidiaries (and the application of the proceeds thereof) giving rise to the need to make such calculation and any incurrence or repayment of other Indebtedness or the issuance or redemption of other Preferred Stock (and the application of the proceeds thereof), other than the incurrence or repayment of Indebtedness in the ordinary course of business for working capital purposes pursuant to revolving credit facilities, occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four-Quarter Period and on or prior to the Transaction Date, as if such incurrence or repayment or issuance or redemption, as the case may be (and the application of the proceeds thereof), had occurred on the first day of the Four-Quarter Period; and (ii) any Asset Sales or other dispositions or Asset Acquisitions (including, without limitation, any Asset Acquisition giving rise to the need to make such calculation as a result of such Person or one of its Restricted Subsidiaries (including any Person who becomes a Restricted Subsidiary as a result of the Asset Acquisition) incurring, assuming or otherwise being liable for Acquired Indebtedness and also including any Consolidated EBITDA attributable to the assets which are the subject of the Asset Acquisition or Asset Sale or other disposition and without regard to clause (iv) of the definition of Consolidated Net Income) occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four Quarter Period and on or prior to the Transaction Date, as if such Asset Sale or other disposition or Asset Acquisition (including the incurrence or assumption of any such Acquired Indebtedness) occurred on the first day of the Four-Quarter Period. If such Person or any of its Restricted Subsidiaries directly or indirectly guarantees Indebtedness of a third Person, the preceding sentence shall give effect to the incurrence of such guaranteed Indebtedness as if such Person or any Restricted Subsidiary of such Person had directly incurred or otherwise assumed such other Indebtedness that was so guaranteed.

Furthermore, in calculating “Consolidated Fixed Charges” for purposes of determining the denominator (but not the numerator) of this “Consolidated Fixed Charge Coverage Ratio”: (i) interest on outstanding Indebtedness determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Indebtedness in effect on the Transaction Date; (ii) notwithstanding clause (i) of this paragraph, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Interest Swap Obligations, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements; (iii) interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Company to be the rate of interest implicit in such Capitalized Lease

Obligation in accordance with GAAP; (iv) for purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period; and (v) interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate.

For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting officer of the Company (including pro forma expense and cost reductions). In addition, any such pro forma calculation, to reflect operating expense reductions reasonably expected to result from any acquisition or merger, may include adjustments as appropriate, in the reasonable determination of the Company as set forth in an Officers’ Certificate, that either (a) would be permitted pursuant to Rule 11-02 of Regulation S-X of the Securities Act or (b) have been realized or for which substantially all the steps necessary for realization have been taken or at the time of determination are reasonably expected to be taken within 12 months following any such acquisition, including, but not limited to, the execution or termination of any contracts, the termination of any personnel or the closing of any facility, as applicable, provided that such adjustments shall be calculated on an annualized basis and will be set forth in an Officers’ Certificate signed by the Company’s chief financial officer and another officer which states in detail (i) the amount of such adjustment or adjustments, and (ii) that such adjustment or adjustments are based on the reasonable good faith beliefs of the officers executing such Officers’ Certificate at the time of such execution.

“Consolidated Fixed Charges” means, with respect to any Person for any period, the sum of, without duplication: (i) Consolidated Interest Expense; plus (ii) the product of (x) the amount of all cash dividend payments on any series of Disqualified Capital Stock of such Person times (y) a fraction, the numerator of which is one and the denominator of which is one minus the then current effective consolidated Federal, state and local income tax rate of such Person, expressed as a decimal (as estimated in good faith by the chief financial officer of the Company, which estimate shall be conclusive); plus (iii) the product of (x) the amount of all dividend payments on any series of Preferred Stock of a Restricted Subsidiary times (y) a fraction, the numerator of which is one and the denominator of which is one minus the then current effective consolidated Federal, state and local income tax rate of such Person, expressed as a decimal (as estimated in good faith by the chief financial officer of the Company, which estimate shall be conclusive); provided that with respect to any series of Preferred Stock that did not pay cash dividends during such period but that is eligible to pay cash dividends during any period prior to the maturity date of the Notes, cash dividends shall be deemed to have been paid with respect to such series of Preferred Stock during such period for purposes of this clause (iii).

“Consolidated Interest Expense” means, with respect to any Person for any period, the sum of, without duplication: (i) the aggregate of all cash and non-cash interest expense with respect to all outstanding Indebtedness of such Person and its Restricted Subsidiaries, including the net costs associated with Interest Swap Obligations and Obligations under Hedging

On the Issue Date, the Trustee shall authenticate and deliver $365,000,000 aggregate principal amount of 7.5% Senior Notes due 2017 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers or by an Officer and an Assistant Secretary of the Company (each an “Authentication Order”). Such order shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated, whether the Notes are to

be Initial Notes, Additional Notes or Exchange Notes, or such other information as the Trustee shall reasonably request and, in the case of an issuance of Additional Notes pursuant to Section 2.14 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09.

The Notes shall be issued only in registered form, without coupons and only in denominations of $2,000 and integral multiples of $1,000.

The Officer signing the Notes for the Company may do so either by way of a manual or facsimile signature.

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

A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Company to authenticate the Notes. Unless limited by the terms of such appointment, 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 the Registrar, or any Paying Agent or agent for service of notices and demands.

The Trustee is hereby authorized to enter into a letter of representations with the Depository (as defined in the Appendix), as the case may be, in the form provided by the Company and to act in accordance with such letter.

Registrar and Paying Agent.

(a) The Company shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an office or agency in the Borough of Manhattan, the City of New York, the State of New York where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their registration of transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Company initially appoints the Trustee as (i) Registrar and Paying Agent in connection with the Notes and (ii) the Notes Custodian with respect to the Global Notes.

(b) The Company shall enter into an appropriate agency agreement with the Registrar or any Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agency agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of any such agent. If the Company fails to appoint or maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly-Owned Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar or transfer agent.

The Registrar and Paying Agent shall be entitled to the rights and immunities of the Trustee hereunder.

Paying Agent to Hold Money in Trust.

Prior to each due date of the principal, premium, if any, and interest on any Note, the Company shall deposit with each Paying Agent (or if the Company or a Wholly-Owned Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal, premium and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on the Notes and shall notify the Trustee in writing 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. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

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 Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish, or cause the Registrar to furnish, to the Trustee, at least five 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 Holders and the Company shall otherwise comply with TIA §312(a).

Transfer and Exchange.

(c) The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note being transferred for registration of transfer and in compliance with the Appendix. When a Note is presented to the Registrar with a request to register a transfer, such Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met.

No service charge shall be made for any registration of transfer or exchange or redemption of the Notes, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 or 9.05 hereof).

(d) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(e) All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

(f) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of the mailing of notice of redemption under Section 3.03 hereof and ending at the close of business on such day, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (c) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

(g) Any holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the holder of such Global Note (or its agent or the person on whose behalf the Global Note is held) or (b) any Holder of a beneficial interest in such Global Note, and that ownership of beneficial interest in such Global Note shall be required to be reflected in a book entry.

(h) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Paying Agent, the Registrar and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if any, and interest on such Notes and for all other purposes, and none of the Trustee, any Paying Agent, the Registrar or the Company shall be affected by notice to the contrary.

(i) None of the Company, the Trustee, any agent of the Company or the Trustee (including any Paying Agent or Registrar) will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

(j) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among depositary participants or beneficial owners of interest in any global security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Replacement Notes.

If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Company or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity or a security bond sufficient in the judgment of the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionally with all other Notes duly issued hereunder.

The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.

Outstanding Notes.

Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions of this Indenture, those delivered to it for cancellation and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal, premium, if any, and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) shall cease to be outstanding and interest on them shall cease to accrue.

Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded.

Temporary Notes.

In the event that Definitive Notes are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes and deliver them in exchange for temporary Notes upon surrender of such temporary Notes at the office or agency of the Company, without charge to the Holder. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as Definitive Notes and to all of the benefits of this Indenture.

Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation in accordance with its customary procedures and, if requested in writing, deliver a certificate of such destruction to the Company unless the Company directs the Trustee in writing to deliver canceled Notes to the Company. The Company may not issue new Notes to replace Notes that it has redeemed, paid or that have been delivered to the Trustee for cancellation. The Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this Indenture.

Defaulted Interest.

If the Company defaults in a payment of interest on the Notes, the Company shall pay defaulted interest then borne by the Notes, as the case may be (plus interest on such defaulted interest at the applicable interest rate on the Notes to the extent lawful), in any lawful manner. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail or cause to be mailed to each affected Holder a notice that states the special record date, the related payment date and the amount of defaulted interest to be paid.

CUSIP or ISIN Numbers.

The Company in issuing the Notes may use “CUSIP”, “ISIN”, or other similar identification numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP”, “ISIN” or such other similar identification numbers in notices of redemption or repurchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or the omission of such numbers. The Company shall promptly notify the Trustee of any change in the “CUSIP”, “ISIN” or such other similar identification numbers.

Issuance of Additional Notes.

The Company shall be entitled, subject to its compliance with Section 4.09, to issue Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Notes issued on the Issue Date, any Additional Notes and all Exchange Notes issued in exchange therefor shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Company shall set forth in a Board Resolution and an Officers’ Certificate of the Company, a copy of each which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(2) the issue price, the issue date and the “CUSIP”, “ISIN” or other similar identification numbers of such Additional Notes; provided, however, that no Additional Notes may be issued at a price that would cause such Additional Notes to have “original issue discount” within the meaning of Section 1273 of the Code; and

(3) whether such Additional Notes shall be Transfer Restricted Notes and issued in the form of Initial Notes as set forth in the Appendix to this Indenture or shall be issued in the form of Exchange Notes as set forth in Exhibit A or Exhibit B, as the case may be, to the Appendix.

Calculation of Amounts.

The maximum amount of Indebtedness, Investments and other threshold amounts that the Company and its Restricted Subsidiaries may incur shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, Investments and other threshold amounts solely as a result of fluctuations in the exchange rate of currencies. When calculating capacity for the incurrence of additional Indebtedness, Investments and other threshold amounts by the Company and its Restricted Subsidiaries, the exchange rate of currencies shall be measured as of the date of such calculation.

ARTICLE 3

REDEMPTION AND PREPAYMENT

Notices to Trustee.

If the Company elects to redeem the Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall notify the Trustee in writing of (i) the Section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed, (iv) the redemption price and (v) the “CUSIP”, “ISIN” or other similar identification numbers of the Notes to be redeemed. The Company shall give notice to the Trustee provided for in this paragraph at least 40 days but not more than 60 days before a redemption date if the redemption is pursuant to Section 3.07 hereof, unless a shorter period is acceptable to the Trustee. Such notice shall be accompanied by an Officers’ Certificate and Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein. If fewer than all the Notes are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which record date shall be not fewer than 15 days after the date of notice to the Trustee. Any such notice may be canceled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect.

Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers fair and appropriate. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; provided that no Notes of a principal amount of $2,000 or less shall be redeemed in part. The provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Notice of Redemption.

Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address.

The notice shall identify the Notes to be redeemed, including “CUSIP”, “ISIN” or other similar identification numbers, if any, and shall state:

(a) the redemption date;

(b) the redemption price and the amount of accrued interest to the redemption date;

(c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

(d) the name and address of the Paying Agent;

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price, plus accrued interest;

(f) that, unless the Company defaults in making such redemption payment or any Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Notes (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

(g) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(h) that no representation is made as to the correctness or accuracy of the “CUSIP”, “ISIN” or other similar identification number, if any, listed in such notice or printed on the Notes.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter period shall be acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price stated in the notice. A notice of redemption may not be conditional. Upon surrender to any Paying Agent, such Notes shall be paid at the redemption price stated in the notice, plus accrued interest, to the redemption date; provided, however, that if the redemption date is after a regular record date and on or prior to the interest payment date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant record date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

Deposit of Redemption Price.

With respect to any Notes, prior to 10:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Wholly-Owned Subsidiary is a Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest, on all Notes or portions thereof to be redeemed on that date other than Notes or portions of Notes called for redemption that have been delivered by the Company to the Trustee for cancellation. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the Company has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Notes to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture.

Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company’s written request, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

Optional Redemption.

(i) Optional Redemption. Except as provided in Sections 3.07(b) and (c) hereof, the Notes, shall not be redeemable at the Company’s option prior to November 15, 2013. On or after November 15, 2013, the Notes shall be subject to redemption at any time at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount thereof) set forth below plus accrued and unpaid interest and additional amounts, if any, to the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date) to the applicable redemption date, if redeemed during the twelve month period commencing on November 15 of the year set forth below:

2014	103.750	%
2015	101.875	%

(j) In addition, prior to November 15, 2013, the Company may redeem the Notes, at its option, in whole at any time or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s registered address, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest and additional amounts, if any to the applicable redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(k) Notwithstanding the foregoing, prior to November 15, 2013, the Company may at its option on one or more occasions redeem the Notes (which includes Additional Notes, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Notes (which includes Additional Notes, if any) originally issued at a redemption price (expressed as a percentage of the principal amount) of 107.5%, plus accrued and unpaid interest to the applicable redemption date, with the net cash proceeds from one or more Equity Offerings; provided, however, that (1) at least 65% of the aggregate principal amount of the Notes remain outstanding immediately after the occurrence of each such redemption (other than Notes held, directly or indirectly, by the Company or its Affiliates); and (2) each such redemption occurs within 60 days after the date of the related Equity Offering.

(l) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Mandatory Redemption; Open Market Purchases.

The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Notes. The Company may at any time and from time to time purchase Notes in the open market or otherwise.

Offer to Purchase by Application of Net Proceeds Offer Amount.

In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence a Net Proceeds Offer (as defined in Section 4.10 hereof), it shall follow the procedures specified below.

The Net Proceeds Offer shall remain open for a period of 20 Business Days following its commencement or such longer period as may be required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company shall purchase the Net Proceeds Offer Amount or, if less than the Net Proceeds Offer Amount has been tendered, all Notes tendered in response to the Net Proceeds Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Net Proceeds Offer.

Upon the commencement of a Net Proceeds Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Net Proceeds Offer. The Net Proceeds Offer shall be made to all Holders. The notice, which shall govern the terms of the Net Proceeds Offer, shall state:

(m) that the Net Proceeds Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Net Proceeds Offer shall remain open and, if the Net Proceeds Offer is also made to holders of Pari Passu Indebtedness of the Company or

Indebtedness of a Restricted Subsidiary of the Company pursuant to Section 4.10 hereof, the notice shall identify such Pari Passu Indebtedness or Indebtedness and state that the Net Proceeds Offer is also made to holders of such Pari Passu Indebtedness or Indebtedness;

(n) the Net Proceeds Offer Amount, the purchase price and the Purchase Date;

(o) that any Note not tendered or accepted for payment shall continue to accrue interest;

(p) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Net Proceeds Offer shall cease to accrue interest after the Purchase Date;

(q) that Holders electing to have a portion of a Note purchased pursuant to a Net Proceeds Offer may only elect to have such Note purchased in integral multiples of $1,000;

(r) that Holders electing to have a Note purchased pursuant to any Net Proceeds Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

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

(t) that, if the aggregate principal amount of the Notes surrendered by Holders and Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company surrendered by the holders thereof exceeds the Offer Amount, the Company shall select the Notes and Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company to be purchased on a pro rata basis (based on the amounts of Notes and such Pari Passu Indebtedness of the Company and Indebtedness of a Restricted Subsidiary of the Company tendered and with such adjustments as may be deemed appropriate by the Company so that only Notes or Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company in denominations of $1,000 or integral multiples thereof shall be purchased); provided that no notes of $2,000 or less shall be tendered in part; and

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

On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Net Proceeds Offer Amount of Notes and Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company or portions thereof tendered pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer Amount has been tendered, all Notes and Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company or portions thereof

tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes or such Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depository or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon written request from the Company, shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Net Proceeds Offer on the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

To the extent that the provisions of any securities laws or regulations conflict with this Section 3.09 or Section 4.10 hereof, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 3.09 or Section 4.10 hereof if the Company so complies.

ARTICLE 4

COVENANTS

Payment of Notes.

The Company shall pay or cause to be paid the principal amount, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. The principal amount, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00 a.m. New York time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay the principal amount, premium, if any, and interest then due. The Company shall pay all Additional Interest, if any, in the same manner on the same dates and in the amounts set forth in the Registration Rights Agreement.

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including postpetition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

Maintenance of Office or Agency.

(a) The Company shall maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or any Registrar) where Notes may be surrendered for registration of transfer or for exchange and where

notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

(b) The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(c) The Company hereby designates the Corporate Trust Office of the Trustee or its Agent, in the Borough of Manhattan, The City of New York, as such office or agency of the Company in accordance with Section 2.03 hereof.

Reports.

(d) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company shall furnish to the Holders of Notes, if not filed electronically with the SEC (i) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, either on the face of the financial statements or in the footnotes thereto and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, the financial condition and results of operations of the Company and its consolidated Subsidiaries) and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants and (ii) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports, in each case, within the time periods specified in the SEC’s rules and regulations. The filing of such reports with the SEC shall constitute delivery thereof to the Holders of the Notes. Whether or not required by the rules and regulations of the SEC, the Company shall file a copy of all such information and reports with the SEC for public availability within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing). The Company shall not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company shall post the reports referred to in the preceding paragraph on its website within the time periods that would apply if the Company were required to file those reports with the SEC. Notwithstanding the foregoing, such requirements shall be deemed satisfied prior to the commencement of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement by the filing when required with the SEC of the Exchange Offer Registration Statement (as defined in the Registration Rights Agreement) and/or Shelf Registration Statement, and any amendments thereto, with such

financial information that satisfies Regulation S-X of the Securities Act. The Company shall at all times comply with TIA § 314(a).

(e) For so long as any Notes remain outstanding, the Company and the Guarantors shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(f) Should the Company deliver to the Trustee any such information, reports or certificates or any annual reports, information, documents and other reports pursuant to TIA § 314(a), delivery of such information, reports or certificates or any annual reports, information, documents and other reports to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Compliance Certificate.

(g) The Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. For purposes of this paragraph, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture. The Company also shall comply with Section 314(a)(4) of the TIA.

(h) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

[Intentionally Omitted].

Stay, Extension and Usury Laws.

The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

Restricted Payments.

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

(1) declare or pay any dividend or make any distribution on or in respect of shares of the Company’s or any Restricted Subsidiary’s Capital Stock to holders of such Capital Stock, including any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries (other than dividends or distributions payable in Qualified Capital Stock of the Company or in options, warrants or other rights to purchase such Qualified Capital Stock and dividends or distributions payable to the Company or a Restricted Subsidiary and other than pro rata dividends or other distributions made by a Subsidiary that is not a Wholly-Owned Subsidiary to minority stockholders (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation));

(2) purchase, redeem or otherwise acquire or retire for value any (i) Capital Stock of the Company, (ii) Capital Stock of any direct or indirect parent of the Company held by Persons other than the Company, (iii) Capital Stock of a Restricted Subsidiary of the Company held by any Affiliate of the Company (other than a Restricted Subsidiary of the Company) or (iv) warrants, rights or options to purchase or acquire shares of any class of such Capital Stock;

(3) make any principal payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire or retire for value, prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Indebtedness of the Company, or of any Guarantor, that is subordinate or junior in right of payment to the Notes or any Guarantee, as applicable (other than the purchase, defeasance or other acquisition of such Indebtedness purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of such purchase, defeasance or other acquisition); or

(4) make any Investment (other than Permitted Investments) (each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a “Restricted Payment”);

if at the time of such Restricted Payment or immediately after giving effect thereto:

(i) a Default or an Event of Default shall have occurred and be continuing (or would result therefrom); or

(ii) the Company is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 4.09 hereof; or

(iii) the aggregate amount of Restricted Payments (including such proposed Restricted Payment) declared or made subsequent to July 1, 2007 (other than Restricted Payments made pursuant to clauses (2), (3), (4), (5), (6), (7), (8), (9), (10), (11) and (12) of the following paragraph) shall exceed the sum of, without duplication:

(u) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Company earned subsequent to July 1, 2007 and on or prior to the date the Restricted Payment occurs (the “Reference Date”) (treating such period as a single accounting period); plus

(v) 100% of the aggregate net cash proceeds (including the fair market value of property other than cash that would constitute Marketable Securities or a Permitted Business) received by the Company from any Person (other than (1) a Subsidiary of the Company and (2) Excluded Contributions) from the issuance and sale subsequent to July 1, 2007 and on or prior to the Reference Date of Qualified Capital Stock of the Company; plus

(w) without duplication of any amounts included in clause (iii)(v) above, 100% of the aggregate net cash proceeds of any equity contribution received subsequent to July 1, 2007 by the Company from a holder of the Company’s Capital Stock (other than Excluded Contributions) (excluding, in the case of clauses (iii)(v) and this (iii)(w), any net cash proceeds from an Equity Offering to the extent used to redeem the Notes in compliance with the provisions set forth under Section 3.07(c) hereof); plus

(x) the amount by which Indebtedness of the Company is reduced on the Company’s balance sheet upon the conversion or exchange subsequent to July 1, 2007 of any Indebtedness of the Company for Qualified Capital Stock of the Company (less the amount of any cash, or the fair value of any other property, distributed by the Company upon such conversion or exchange); provided, however, that the foregoing amount shall not exceed the net cash proceeds received by the Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding net cash proceeds from sales to a Subsidiary of the Company or to an employee stock ownership plan or a trust established by the Company or any of its Subsidiaries for the benefit of their employees); plus

(y) an amount equal to the sum of (I) 100% of the aggregate net proceeds (including the fair market value of property other than cash that would constitute Marketable Securities or a Permitted Business) received by the Company or any Restricted Subsidiary (A) from any sale or other disposition of any Investment (other than a Permitted Investment) in any Person (including an Unrestricted Subsidiary) made by the Company and its Restricted Subsidiaries and (B) representing the return of capital or principal (excluding dividends and distributions otherwise included in Consolidated Net Income) with respect to such Investment, and (II) the portion (proportionate to the Company’s equity interest in an Unrestricted Subsidiary) of the fair market value of the net assets of an

Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that, in the case of item (II), the foregoing sum shall not exceed, in the case of any Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary and; provided further, that no amount will be included under this clause (y) to the extent it is already included in Consolidated Net Income; plus

(z) $25,000,000.

Notwithstanding the foregoing, the provisions set forth in the immediately preceding paragraph shall not prohibit:

(1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of such dividend or notice of such redemption if the dividend or payment of the redemption price, as the case may be, would have been permitted on the date of declaration or notice;

(2) any Restricted Payment made out of the net cash proceeds of the substantially concurrent sale of, or made by exchange for, Qualified Capital Stock of the Company (other than Capital Stock issued or sold to a Subsidiary of the Company or an employee stock ownership plan or to a trust established by the Company or any of its Subsidiaries for the benefit of their employees) or a substantially concurrent cash capital contribution received by the Company from its shareholders; provided, however, that the net cash proceeds from such sale or such cash capital contribution (to the extent so used for such Restricted Payment) shall be excluded from the calculation of amounts under clauses (iii)(w) and (iii)(x) of the immediately preceding paragraph;

(3) the acquisition of any Indebtedness of the Company or a Guarantor that constitutes a Subordinated Obligation to the Notes or the applicable Guarantee through the application of net proceeds of a substantially concurrent sale for cash (other than to a Subsidiary of the Company) of Refinancing Indebtedness that constitutes a Subordinated Obligation to the Notes or the applicable Guarantee;

(4) if no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof, the declaration and payment of dividends to holders of any class or series of Designated Preferred Stock (other than Disqualified Capital Stock), issued after the Issue Date; provided that, at the time of the issuance of such stock, the Company, after giving effect to such issuance on a pro forma basis, would have had a Consolidated Fixed Charge Coverage Ratio of at least 2.0 to 1.0;

(5) the purchase, redemption or other acquisition, cancellation or retirement for value of Capital Stock, or options, warrants, equity appreciation rights or other rights to purchase or acquire Capital Stock of the Company or any Restricted Subsidiary or any direct or indirect parent of the Company held by any existing or former employees or management of the Company or any Subsidiary of the Company, or their assigns, estates or heirs, in each case in

connection with the repurchase provisions of employee stock option or stock purchase agreements or other agreements to compensate management employees, or upon the death, disability, retirement, severance or termination of employment of management employees; provided that all such redemptions or repurchases pursuant to this clause (5) shall not exceed in any fiscal year the sum of (A) $5.0 million plus (B) any amounts not utilized in any preceding fiscal year following the Issue Date that were otherwise available under this clause for such purchases (which aggregate amount shall be increased by the amount of any net cash proceeds received from the sale since the Issue Date of Capital Stock (other than Disqualified Capital Stock) to members of the Company’s management team that have not otherwise been applied to the payment of Restricted Payments pursuant to the terms of clause (iii) of the immediately preceding paragraph or clause (2) of this paragraph and by the cash proceeds of any “key-man” life insurance policies which are used to make such redemptions or repurchases); provided, further, that the cancellation of Indebtedness owing to the Company from members of management of the Company or any of its Restricted Subsidiaries in connection with any repurchase of Capital Stock of the Company (or warrants or options or rights to acquire such Capital Stock) will not be deemed to constitute a Restricted Payment under this Indenture;

(6) repurchases of Capital Stock deemed to occur upon the exercise of stock options, warrants or other convertible securities if such Capital Stock represents a portion of the exercise price thereof;

(7) additional Restricted Payments in an aggregate amount not to exceed $30.0 million;

(9) if no Default or Event of Default shall have occurred and be continuing, Restricted Payments made with Net Cash Proceeds from Asset Sales remaining after application thereof as required by Section 4.10 hereof (including after the making by the Company of any Net Proceeds Offer required to be made by the Company pursuant to such Section 4.10 and the application of the entire Net Proceeds Offer Amount to purchase Notes tendered therein);

(10) upon the occurrence of a Change of Control and within 60 days after the completion of the Change of Control Offer pursuant to Section 4.15 hereof (including the purchase of all Notes tendered), any purchase or redemption of Obligations of the Company that are subordinate or junior in right of payment to the Notes required pursuant to the terms thereof as a result of such Change of Control at a purchase or redemption price not to exceed 101% of the outstanding principal amount thereof, plus accrued and unpaid interest thereon, if any; provided, however, that (A) at the time of such purchase or redemption, no Default or Event of Default shall have occurred and be continuing (or would result therefrom), (B) the Company would be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 4.09 hereof after giving pro forma effect to such Restricted Payment and (C) such purchase or redemption is not made, directly or indirectly, from the proceeds of (or made in anticipation of) any issuance of Indebtedness by the Company or any Subsidiary;

(11) Investments that are made with Excluded Contributions; and

(12) the repayment of the Senior Subordinated Notes.

In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date in accordance with clause (iii) of the immediately preceding paragraph of this Section 4.07, (a) amounts expended pursuant to clause (1) of the immediately preceding paragraph shall be included in such calculation, and (b) amounts expended pursuant to clauses (2), (3), (4), (5), (6), (7), (8), (9), (10), (11) and (12) of the immediately preceding paragraph shall be excluded from such calculation.

The Board of Directors of the Company may designate any Restricted Subsidiary of the Company to be an Unrestricted Subsidiary as specified in the definition of “Unrestricted Subsidiary”. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time of the designation and shall reduce the amount available for Restricted Payments under the first paragraph of this Section 4.07. All of those outstanding Investments shall be deemed to constitute Investments in an amount equal to the fair market value of the Investments at the time of such designation. Such designation shall only be permitted if the Restricted Payment would be permitted at the time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Dividend and Other Payment Restrictions Affecting Subsidiaries.

The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Company to: (a) pay dividends or make any other distributions on or in respect of its Capital Stock (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock); (b) make loans or advances or pay any Indebtedness or other obligation owed to the Company or any Guarantor (it being understood that the subordination of loans or advances made to the Company or any Guarantor to other Indebtedness incurred by the Company or any Guarantor shall not be deemed a restriction on the ability to make loans or advances); or (c) transfer any of its property or assets to the Company or any Guarantor, except, with respect to clauses (a), (b) and (c), for such encumbrances or restrictions existing under or by reason of: (1) applicable law; (2) this Indenture; (3) non-assignment provisions of any contract or any lease of any Restricted Subsidiary of the Company entered into in the ordinary course of business; (4) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; (5) the Credit Facility as in effect on the Issue Date or any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that any restrictions imposed pursuant to any such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing are ordinary and customary with respect to syndicated bank loans (under the relevant circumstances), as determined in good faith by the Company’s Board of Directors, which determination will be conclusive; (6) agreements existing on the Issue Date to the extent and in the manner such agreements are in effect on the Issue Date; (7) restrictions on the transfer of

assets subject to any Lien permitted under this Indenture imposed by the holder of such Lien; (8) restrictions imposed by any agreement to sell assets or Capital Stock of a Restricted Subsidiary permitted under this Indenture to any Person pending the closing of such sale; (9) any agreement or instrument governing Capital Stock of any Person that is acquired; (10) any Purchase Money Note or other Indebtedness or other contractual requirements of a Securitization Entity in connection with a Qualified Securitization Transaction, as determined in good faith by the Company’s Board of Directors, which determination will be conclusive; provided that such restrictions apply only to such Securitization Entity; (11) other Indebtedness outstanding on the Issue Date or permitted to be issued or incurred under this Indenture; provided that any such restrictions are ordinary and customary with respect to the type of Indebtedness being incurred (under the circumstances), as determined in good faith by the Company’s Board of Directors, which determination will be conclusive; (12) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; and (13) any encumbrances or restrictions imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (2) through (4) and (6) through (12) above; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company’s Board of Directors (evidenced by a Board Resolution) whose judgment shall be conclusively binding, not materially more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

Incurrence of Indebtedness.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, “incur”) any Indebtedness (other than Permitted Indebtedness); provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Company and the Guarantors may incur Indebtedness (including, Acquired Indebtedness), and Restricted Subsidiaries of the Company that are not Guarantors may incur Acquired Indebtedness in an aggregate amount not to exceed $20.0 million at any time outstanding, in each case if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of the Company would have been greater than 2.0 to 1.0. The maximum amount of Indebtedness that the Company and its Restricted Subsidiaries may incur pursuant to this Section 4.09 shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies. When calculating capacity for the incurrence of additional Indebtedness by the Company and its Restricted Subsidiaries pursuant to this covenant the exchange rate of currencies shall be measured as of the date of such calculation.

Asset Sales.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (i) the Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets sold or otherwise disposed of (as determined in good faith by the Company’s Board of Directors, which determination will be conclusive); (ii) at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of cash or Cash Equivalents; provided, however, that the amount of: (a) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets; (b) any notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received); and (c) any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed 5% of Total Assets at the time of the receipt of such Designated Noncash Consideration (with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value), shall, in each of (a), (b) and (c) above, be deemed to be cash for the purposes of this provision or for purposes of the second paragraph of this Section 4.10; and (iii) upon the consummation of an Asset Sale, the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof (A) to prepay any Pari Passu Indebtedness of the Company or a Guarantor (including the Notes) or any Indebtedness (other than Disqualified Capital Stock) of a Restricted Subsidiary that is not a Guarantor and, in the case of any such Indebtedness under any revolving credit facility, effect a corresponding reduction in the availability under such revolving credit facility (or effect a permanent reduction in the availability under such revolving credit facility regardless of the fact that no prepayment is required in order to do so (in which case no prepayment should be required)), (B) to reinvest in Productive Assets (provided that this requirement shall be deemed satisfied if the Company or such Restricted Subsidiary by the end of such 365-day period has entered into a binding agreement under which it is contractually committed to reinvest in Productive Assets and such investment is consummated within 120 days from the date on which such binding agreement is entered into and, with respect to the amount of such investment, the reference to the 366th day after an Asset Sale in the first sentence of the following paragraph shall be deemed to be a reference to the 121st day after the date on which such binding agreement is entered into (but only if such 121st day occurs later than such 366th day)), or (C) a combination of prepayment and investment permitted by the foregoing clauses (iii)(A) and (iii)(B). Pending the final application of any such Net Cash Proceeds, the Company or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents. On the 366th day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company or of such Restricted Subsidiary determines by Board Resolution not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (iii)(A), (iii)(B) and (iii)(C) of the next preceding sentence (each, a “Net Proceeds Offer Trigger Date”), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (iii)(A),

(iii)(B) and (iii)(C) of the preceding paragraph (each a “Net Proceeds Offer Amount”) shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the “Net Proceeds Offer”) on a date (the “Net Proceeds Offer Payment Date”) not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, from all Holders and holders of any other Pari Passu Indebtedness of the Company or a Restricted Subsidiary of the Company requiring the making of such an offer, on a pro rata basis, the maximum amount of Notes and such other Pari Passu Indebtedness that may be purchased with the Net Proceeds Offer Amount at a price equal to 100% of their principal amount (or, in the event such other Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company was issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest thereon, if any, to the date of purchase (or, in respect of such other Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness of the Company or Indebtedness of a Restricted Subsidiary of the Company); provided, however, that if at any time any non-cash consideration (including any Designated Noncash Consideration) received by the Company or any Restricted Subsidiary of the Company, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this Section 4.10. Notwithstanding the foregoing, if a Net Proceeds Offer Amount is less than $15.0 million, the application of the Net Cash Proceeds constituting such Net Proceeds Offer Amount to a Net Proceeds Offer may be deferred until such time as such Net Proceeds Offer Amount plus the aggregate amount of all Net Proceeds Offer Amounts arising subsequent to the Net Proceeds Offer Trigger Date relating to such initial Net Proceeds Offer Amount from all Asset Sales by the Company and its Restricted Subsidiaries aggregates at least $15.0 million, at which time the Company or such Restricted Subsidiary shall apply all Net Cash Proceeds constituting all Net Proceeds Offer Amounts that have been so deferred to make a Net Proceeds Offer (the first date the aggregate of all such deferred Net Proceeds Offer Amounts is equal to $15.0 million or more shall be deemed to be a Net Proceeds Offer Trigger Date).

Notwithstanding the immediately preceding two paragraphs, the Company and its Restricted Subsidiaries shall be permitted to consummate an Asset Sale without complying with such paragraph to the extent that: (i) at least 75% of the consideration for such Asset Sale constitutes Productive Assets, cash, Cash Equivalents and/or Marketable Securities; and (ii) such Asset Sale is for fair market value; provided that any consideration consisting of cash, Cash Equivalents and/or Marketable Securities received by the Company or any of its Restricted Subsidiaries in connection with any Asset Sale permitted to be consummated under this paragraph shall constitute Net Cash Proceeds subject to the provisions of the two preceding paragraphs.

Notice of each Net Proceeds Offer will be mailed to the record Holders as shown on the register of Holders within 30 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in Section 3.09 hereof. To the extent that the aggregate amount of Notes and any Pari Passu Indebtedness of the Company or any Indebtedness of a Restricted Subsidiary of the Company tendered pursuant to a Net Proceeds Offer is less than the Net Proceeds Offer Amount, the Company may use any remaining Net

Proceeds Offer Amount for general corporate purposes or for any other purpose not prohibited by this Indenture. Upon completion of any such Net Proceeds Offer, the Net Proceeds Offer Amount shall be reset at zero.

The Company shall 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 repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue thereof.

Transactions with Affiliates.

(i) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to occur any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates involving aggregate consideration in excess of $3.0 million (an “Affiliate Transaction”), other than Affiliate Transactions on terms that are not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company; provided, however, that for a transaction or series of related transactions with an aggregate value of $10.0 million or more, at the Company’s option, either: (i) a majority of the disinterested members of the Board of Directors of the Company shall determine in good faith that such Affiliate Transaction is on terms that are not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company, or (ii) the Board of Directors of the Company or any such Restricted Subsidiary party to such Affiliate Transaction shall have received an opinion from a nationally recognized investment banking, appraisal or accounting firm that such Affiliate Transaction is either fair, from a financial standpoint, to the Company and its Restricted Subsidiaries or is on terms not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company; and provided, further, that for an Affiliate Transaction with an aggregate value of $20.0 million or more the Board of Directors of the Company or any such Restricted Subsidiary party to such Affiliate Transaction shall have received a written opinion from a nationally recognized investment banking, appraisal or accounting firm that such Affiliate Transaction is either fair, from a financial standpoint, to the Company and its Restricted Subsidiaries or is on terns not materially less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company.

(j) The restrictions set forth in Section 4.11(a) hereof shall not apply to: (i) reasonable fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary of the Company as determined in good faith by the Company’s Board of Directors or senior management; (ii) transactions between or among the Company and any of its Restricted Subsidiaries or any entity

that becomes a Restricted Subsidiary as a result of such transaction (other than a Securitization Entity) or exclusively between or among such Restricted Subsidiaries or any entity that becomes a Restricted Subsidiary as a result of such transaction, provided that such transactions are not otherwise prohibited by this Indenture; (iii) any agreement as in effect as of the Issue Date or any amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto) or by any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders in any material respect than the original agreement as in effect on the Issue Date as determined in good faith by the Board of Directors of Company; (iv) Restricted Payments or Permitted Investments permitted by this Indenture; (v) transactions effected as part of a Qualified Securitization Transaction; (vi) payments or loans allowed by law to employees or consultants that are approved by the Board of Directors of the Company in good faith; (vii) sales of Qualified Capital Stock; (viii) the existence of, or the performance by the Company or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders’ agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Company or any of its Restricted Subsidiaries of obligations under, any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (viii) to the extent that the terms of any such amendment or new agreement are not disadvantageous to the Holders of Notes in any material respect; (ix) transactions permitted by, and complying with, the provisions of Article 5 hereof; (x) any issuance of securities or other payments, awards, grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans approved by the Board of Directors of the Company; (xi) transactions in which the Company or any Restricted Subsidiary delivers to the Trustee a letter from a nationally recognized investment banking, appraisal or accounting firm stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view; and (xii) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture that are fair to the Company or the Restricted Subsidiaries, in the reasonable determination of the members of the Board of Directors of the Company, which determinations shall be conclusive, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party.

Liens.

The Company shall not and shall not cause or permit any Guarantor to incur any Secured Debt that is secured by a Lien (other than Permitted Liens) upon any of its property or assets (including Capital Stock of Subsidiaries), unless contemporaneously therewith such Person makes effective provision to secure the Indebtedness due under this Indenture and the Notes and, in respect of Liens on any Restricted Subsidiary’s property or assets, the relevant Guarantee, equally and ratably (or senior in priority to in the case of Liens with respect to Subordinated Obligations of the Company or the Guarantors) with such Secured Debt for so long as such Secured Debt is secured by a Lien (the “Initial Lien”).

Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall provide by its terms that such Lien shall be automatically and unconditionally

released and discharged upon the release and discharge of the Lien securing the other Secured Debt.

Conduct of Business.

The Company shall not and shall not permit any of its Restricted Subsidiaries to, engage in any businesses a majority of whose revenues are not derived from businesses that are the same or reasonably similar, ancillary or related to, or a reasonable extension, development or expansion of, the businesses in which the Company and its Restricted Subsidiaries are engaged on the Issue Date (which shall include, without limitation, business or operations of the Company’s suppliers and customers).

Corporate Existence.

Subject to Article 5 and Section 11.06 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and 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 and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors 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, and that the loss thereof would not have an adverse effect on the ability of the Company to perform its obligations under the Notes or this Indenture.

Offer to Repurchase upon Change of Control.

(k) If a Change of Control occurs, each Holder shall have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued interest to the date of purchase. Within 30 days following the date upon which the Change of Control occurred, the Company must send, by first class mail, a notice to the Trustee and each Holder, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). Holders electing to have a Note purchased pursuant to a Change of Control Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

(l) On the Change of Control Payment Date, the Company shall, to the extent lawful, (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (2) 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 (3) deliver or cause to be

delivered to the applicable Trustee the Notes so accepted together with an Officers’ Certificate stating the principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail or deliver (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 that each such new Note will be in a principal amount of $1,000 or an integral multiple thereof. 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.

Prior to the mailing of the notice referred to in Section 4.15(a) above, and as a condition to such mailing (i) the requisite holders of each issue of Indebtedness issued under an indenture or other agreement that may be violated by such payment shall have consented to such Change of Control Offer being made and waived the event of default, if any, caused by the Change of Control or (ii) the Company will repay all outstanding Indebtedness issued under an indenture or other agreement that may be violated by a payment to the holders of Notes under a Change of Control Offer or the Company must offer to repay all such Indebtedness, and make payment to the holders of such Indebtedness that accept such offer, and obtain waivers of any event of default from the remaining holders of such Indebtedness. The Company covenants to effect such repayment or obtain such consent within 30 days following any Change of Control. The Company’s failure to comply with the covenant described in the immediately preceding sentence shall constitute an Event of Default described in clause (c) and not in clause (b) under Section 6.01 hereof.

(m) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the Company complies with the provisions of any such securities laws or regulations, the Company shall not be deemed to have breached its obligations under this Section 4.15.

(n) Notwithstanding anything to the contrary in this Section 4.15, the Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 hereof and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

Limitation on Preferred Stock of Restricted Subsidiaries.

The Company shall not permit any of its Restricted Subsidiaries to issue any Preferred Stock (other than to the Company or to a Restricted Subsidiary of the Company) or permit any Person (other than the Company or a Restricted Subsidiary of the Company) to own any Preferred Stock of any Restricted Subsidiary of the Company, other than Permitted Subsidiary Preferred Stock. The provisions of this Section 4.16 will not apply to (w) any of the Guarantors for so long as such Restricted Subsidiary remains a Guarantor, (x) any transaction as a result of which neither the Company nor any of its Restricted Subsidiaries will own any Capital Stock of the Restricted Subsidiary whose Preferred Stock is being issued or sold and (y) Preferred Stock (including Disqualified Capital Stock) that is issued in compliance with Section 4.09 hereof.

Future Guarantees by Domestic Subsidiaries.

At any time at which the Company’s Credit Facilities require a guarantee of any of the Domestic Subsidiaries, the Company shall cause each of its Domestic Subsidiaries to execute and deliver a supplemental indenture to this Indenture, providing for a guarantee of payment on a senior basis of the Notes by such Domestic Subsidiary; provided, however, that such Domestic Subsidiary need not execute and deliver such a supplemental indenture for so long as such Domestic Subsidiary has Total Assets of $10,000 or less, total Indebtedness of $10,000 or less and does not own any of the material Intellectual Property of the Company and its Subsidiaries. In addition, to the extent the Company has no Credit Facilities in place, any Domestic Subsidiary that has $5.0 million or more of other then outstanding Indebtedness owed to a Person other than the Company or another Restricted Subsidiary, the Company will cause such Domestic Subsidiary to execute and deliver a supplemental indenture to this Indenture, providing for a guarantee of payment on a senior basis of the Notes by such Domestic Subsidiary.

However, transfer of assets (i) between or among the Company and its Restricted Subsidiaries, (ii) between and among Foreign Subsidiaries that are Restricted Subsidiaries or (iii) from Foreign Subsidiaries to the Company or a Guarantor will not be subject to this Section 5.01.

Upon any consolidation, combination or merger, or any transfer of all or substantially all of the assets of the Company in accordance with Section 5.01 hereof, in which the Company is not the continuing corporation, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture and the Notes with the same effect as if such surviving entity had been named as such and that, in the event of a conveyance or transfer (but not a lease), the conveyor or transferor (but not a lessor) shall be released from the provisions of this Indenture.

ARTICLE 6

DEFAULTS AND REMEDIES

Events of Default.

“Event of Defaults” are:

(a) the failure to pay interest or any Additional Interest (as required by the Registration Rights Agreement) on any Notes when the same becomes due and payable if the default continues for a period of 30 days;

(b) the failure to pay the principal of or premium, if any, on any Notes when such principal or premium, if any, becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer on the date specified for such payment in the applicable offer to purchase);

(c) a default in the observance or performance of any other covenant or agreement contained in this Indenture which default continues for a period of 60 days after the Company receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the case of a default with respect to Section 5.01 hereof, which will constitute an Event of Default with such notice requirement but without such passage of time requirement);

(d) the failure to pay at final stated maturity (after giving effect to any applicable grace periods and any extensions thereof) the principal amount of any Indebtedness of the Company or any Significant Subsidiary of the Company (other than a Securitization Entity) or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), or the acceleration of the final stated maturity of any such Indebtedness, if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness, whether such Indebtedness now exists, or is created after the date of this Indenture, in default for failure to pay principal at final maturity or which has been accelerated, aggregates $20.0 million or more at any time;

(e) one or more judgments in an aggregate amount in excess of $20.0 million (which are not covered by insurance or indemnity as to which the insurer or a creditworthy indemnitor has not disclaimed coverage) shall have been rendered against the Company or any of its Significant Subsidiaries or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable;

(f) the Company or any of its Significant Subsidiaries or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a 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; or

(iv) makes a general assignment for the benefit of its creditors;

(g) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(i) is for relief against the Company or any of its Significant Subsidiaries or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary;

(ii) appoints a custodian of the Company or any of its Significant Subsidiaries or for all or substantially all of the property of the Company or any of its Significant Subsidiaries or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary; or

(iii) orders the liquidation of the Company or any of its Significant Subsidiaries or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary;

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

(h) any Guarantee of a Significant Subsidiary, or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary, ceases to be in full force and effect (except as contemplated by the terms of this Indenture) or is declared null and void in a judicial proceeding or any Guarantor that is a Significant Subsidiary or group of Guarantors that taken together (as of the latest audited consolidated financial statements of the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary denies or disaffirms its obligations under this Indenture or its Guarantee.

Acceleration.

If any Event of Default (other than an Event of Default specified in clause (f) or (g) of Section 6.01 hereof with respect to the Company) shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare the principal of and accrued interest on all the Notes to be due and payable immediately by notice in writing to the Company and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration” (the “Acceleration Notice”), and the same shall become immediately due and payable. If an Event of Default specified in clause (f) or (g) of Section 6.01 hereof with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

At any time after a declaration of acceleration with respect to the Notes as described in the preceding paragraph, the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences: (i) if the rescission would not conflict with any judgment or decree; (ii) if all existing Events of Default have been cured or waived except nonpayment of principal of, premium, if any, and interest on the Notes that has become due solely because of the acceleration; (iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (iv) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and (v) in the event of the cure or waiver of an Event of Default of the type described in clause (f) or (g) of Section 6.01 hereof, the Trustee shall have received an

Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and 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.

Waiver of Past Defaults.

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an 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, premium and 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.

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, 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.

Limitation on Suits.

Except to enforce the right to receive payment of principal, premium, if any, or interest when due, a Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if:

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

(j) 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;

(k) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity reasonably satisfactory to the Trustee;

(l) 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 indemnity; and

(m) 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.

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, premium 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.

Collection Suit by Trustee.

If an Event of Default specified in Section 6.01 (a) or (b) hereof 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 amount of, premium and interest remaining unpaid on the Notes and interest on overdue principal 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.

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 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.

Priorities.

Any money collected by the Trustee pursuant to this Article and any other money or property distributable in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied in the following order:

FIRST: to the Trustee (including a predecessor 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 (including a predecessor Trustee) and the costs and expenses of collection;

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

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, 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.

ARTICLE 7

TRUSTEE

SECTION 7.01. Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

(b) Except during the continuance of an Event of Default:

(l) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(m) Notwithstanding Section 6.05 hereof, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of Indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. The Registrar or any Paying Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Notice of Defaults.

(t) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(u) Within the earlier of 90 days after the occurrence of a Default or an Event of Default or 30 days after it is actually known to a Responsible Officer, the Trustee shall mail to Holders of Notes, as their names and addresses appear in the security register for the Notes, a notice of the Default or Event of Default known to the Trustee, unless such Default or Event of Default shall have been cured or waived. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Reports by Trustee to Holders of the Notes.

As promptly as practical but within 60 days after each April 30 beginning with April 30, 2005, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange and any delisting thereof.

Compensation and Indemnity.

The Company shall pay to the Trustee from time to time such compensation for its services as the parties shall agree from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee’s agents and counsel. The Company and each Guarantor, jointly and severally shall indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or a Guarantee against the Company or a Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by the Company, any Guarantor, any Holder or any other Person). The Trustee shall notify the Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company or any Guarantor of its indemnity obligations hereunder. The Company shall defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company and the Guarantors, as applicable shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, or negligence.

The obligations of the Company and the Guarantors under this Section 7.07 shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the termination of this Indenture.

To secure the Company’s and the Guarantors’ payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, other than money or property held in trust to pay principal and interest on particular Notes. Such Lien shall survive the resignation or removal of the Trustee, the satisfaction and discharge and the termination of this Indenture.

In addition, and without prejudice to the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(f) or (g) 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 Bankruptcy Law.

“Trustee” for purposes of this Section shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence, or willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable.

Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing and may appoint a successor trustee. The Company may remove the Trustee if:

(v) the Trustee fails to comply with Section 7.10 hereof;

(w) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(x) a custodian or public officer takes charge of the Trustee or its property; or

(y) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee, after written request by any Holder of a Note who has been a bona fide holder of a Note for at least six months, fails to comply with Section 7.10, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.02. Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another Person, the resulting, surviving, transferee or successor Person without any further act shall be the successor Trustee. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

Eligibility; Disqualification.

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any State thereof, that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a). The Trustee is subject to TIA § 310(b).

Preferential Collection of Claims Against Company.

The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311 (a) to the extent indicated therein.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE SECTION

Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). 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, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 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 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 amount, premium, if any, and interest on such Notes when such payments are due, (b) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith and (d) the provisions of this Article 8 with respect to Legal Defeasance. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof 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 (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company 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(d) and 6.01(e) hereof shall not constitute Events of Default.

Conditions to Legal or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes:

In order to exercise either Legal Defeasance or Covenant Defeasance:

(a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Obligations, or a combination of United States dollars and Government Obligations, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal amount, premium, if any, and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States of America reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such Legal Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States of America reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such Covenant Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien to securing such borrowing);

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under this Indenture (other than a Default or an Event of

Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing) or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;

(g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and

(h) the Company shall have paid or duly provided for payment of all amounts then due to the Trustee pursuant to Section 7.07 hereof.

Notwithstanding the foregoing, the Opinion of Counsel required by clause (b) above with respect to a Legal Defeasance need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation (A) have become due and payable, or (B) will become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of the principal amount, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Obligations deposited pursuant to Section 8.04 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.

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Obligations held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification

thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Satisfaction and Discharge.

This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights or registration of transfer or exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes when (i) either (a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation or; (b) all Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable, (y) will become due and payable within one year, or (z) are to be called for redemption within one year under irrevocable arrangements satisfactory to the Trustee in its sole discretion for the giving of notice of redemption by the Trustee in the name and expense of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; (ii) the Company has paid all other sums payable under this Indenture by the Company; and (iii) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with.

Repayment to Company.

Each of the Trustee and each Paying Agent shall promptly turn over to the Company upon request any money or Government Obligations held by it as provided in this Article which, in the written opinion of nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if Government Obligations have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article.

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Company for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or noncallable Government Obligations in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or

otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided however, that, if the Company makes any payment of principal, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Survival.

The Trustee’s rights under this Article 8 shall survive termination of this Indenture.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

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, the Guarantees 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 (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code) or to alter the provisions of Article 2 or the Appendix hereof relating to the form of the Notes (including the related definitions) in a manner that does not adversely affect any Holder in any material respect;

(c) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the Notes by a successor to the Company or a Guarantor pursuant to Article 5 or Section 11.06 hereof;

(d) 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 Notes in any material respect;

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

(f) to provide for the issuance of Notes issued after the Issue Date in accordance with the limitations set forth in this Indenture;

(g) to release any Guarantor from its Guarantee in accordance with this Indenture;

(h) to allow any Guarantor to execute a supplemental indenture and/or a Guarantee with respect to the Notes;

(i) to secure the Notes;

(j) to provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or eliminated as appropriate) and which shall be treated, together with any outstanding Notes, as a single class of securities; or

(k) to conform the text of this Indenture, the Notes or the Guarantees to any provision of the “Description of notes” section of the Offering Memorandum to the extent that such provision in the “Description of notes” is intended to be a verbatim recitation of a provision of this Indenture, the Notes or the Guarantees.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 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.

With Consent of Holders of Notes.

(l) Except as provided below in this Section 9.02, this Indenture (including Sections 3.09, 4.10 and 4.15 hereof), the Guarantees 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 voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Guarantees or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

(m) Upon the request of the Company accompanied by a resolution of its Board of Directors 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 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the

Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture.

(n) 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 or waiver, but it shall be sufficient if such consent approves the substance thereof.

(o) 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 aggregate principal amount of the Notes then outstanding voting as a single class 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 or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any Note;

(3) reduce the principal of or change or have the effect of changing the fixed maturity of any Note, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor;

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

(5) make any change in the provisions of this Indenture protecting the right of each Holder to receive payment of principal of or interest on any Note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of Default;

(6) after the Company’s obligation to purchase Notes arises thereunder, amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control or modify any of the provisions or definitions with respect thereto after a Change of Control has occurred;

(7) make any change affecting the ranking of the Notes in a manner which adversely affects the Holders; or

(8) make any change in the amendment provisions which require each Holder’s consent or in the waiver provisions.

Compliance with Trust Indenture Act

From the date on which this Indenture is qualified under the TIA, every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental Indenture that complies with the TIA as then in effect.

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.

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, upon receipt of an Authentication Order, 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.

Trustee to Sign Amendments, etc.

ARTICLE 11

GUARANTEES

Guarantees.

Each Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Notes when due, whether at maturity, by acceleration, by redemption or otherwise, of all obligations of the Company under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal of, premium, if any, or interest on in respect of the Notes and all other monetary obligations of the Company under this Indenture and the Notes and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Notes whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor and that each such Guarantor will remain bound under this Article 11 notwithstanding any extension or renewal of any Guaranteed Obligation.

Each Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (a) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of this Indenture, the Notes or any other agreement; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any Guarantor; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Obligations; or (f) except as set forth in Section 11.07, any change in the ownership of such Guarantor.

Each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives any right to which it may be entitled to have the assets of the Company first be used and depleted as payment of the Company’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from

or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Company be sued prior to an action being initiated against such Guarantor.

Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

Except as expressly set forth in Sections 11.02 and 11.07 hereof, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (1) the unpaid principal amount of such Guaranteed Obligations, (2) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (3) all other monetary obligations of the Company to the Holders and the Trustee.

Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Guaranteed Obligations may be accelerated as provided in Article 6 for the purposes of such Guarantor’s Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such

Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section.

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section.

Upon request of the Trustee (which request the Trustee shall under no circumstances be obligated to make), each Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

Limitation on Liability.

Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Successors and Assigns.

This Article 11 shall be binding upon each Guarantor and its successors and assigns 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 upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

No Waiver.

Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise.

Modification.

No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Guarantors May Consolidate, etc., on Certain Terms.

Each Guarantor shall not, and the Company shall not permit any such Guarantor to, consolidate or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of, in a single transaction or series of related transactions, all or substantially all of its assets to any Person unless:

(1) (except in the case of such Guarantor that has been disposed of in its entirety to another Person (other than to the Company or a Restricted Subsidiary), whether through a merger, consolidation or sale of Capital Stock or through the sale of all or substantially all of its assets (such sale constituting the disposition of such Guarantor in its entirety), if in connection therewith the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.10 hereof in respect of such disposition) the resulting, surviving or transferee Person (if not such Guarantor) shall be a Person organized and validly existing under the laws of the jurisdiction under which such Guarantor was organized or under the laws of the United States of America, any State thereof or the District of Columbia, and such Person shall expressly assume, by a supplemental indenture (in form satisfactory to the Trustee), executed and delivered to the Trustee, all the obligations of such Guarantor, if any, under its Guarantee;

(2) except in the case of a merger of such Guarantor with or into the Company or another Restricted Subsidiary of the Company that is a Guarantor and except in the case of a merger entered into solely for the purpose of reincorporating such Guarantor in another jurisdiction, immediately after giving effect to such transaction and the assumption contemplated by the immediately preceding clause (1) (including, without limitation, giving effect to any Indebtedness and Acquired Indebtedness incurred and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred and be continuing; and

(3) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with the applicable provisions of this Indenture and that all conditions precedent in this Indenture relating to such transaction have been satisfied.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee of the Notes and the due and punctual performance of all of the covenants and conditions 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. Such successor Person thereupon may cause to be signed any or all of the Guarantees of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof.

Release of Guarantor.

(b) Upon the sale or other disposition (including by way of consolidation or merger) of a Guarantor that is a Restricted Subsidiary of the Company or the sale or disposition of all or substantially all the assets of such Guarantor (in each case other than a sale or disposition to the Company or an Affiliate of the Company and if in connection therewith the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.10 hereof in respect of such disposition),

(d) at such time, and for so long as, the Company’s Credit Facilities do not require any guarantees of the Domestic Subsidiaries, or

(e) to the extent the Company has no Credit Facilities in place, such Guarantor does not have $5.0 million or more of other than outstanding Indebtedness owed to a Person other than the Company or another Restricted Subsidiary,

such Guarantor shall be deemed released from all obligations under this Article 11 without any further action required on the part of the Trustee or any Holder.

If the Company exercises its Legal Defeasance option or its Covenant Defeasance option in accordance with the provisions of Article 8 hereof or if its obligations under this Indenture are discharged in accordance with Section 8.06 hereof, each Guarantor shall be released from all obligations under this Article 11 without any further action required on the part of the Trustee or any Holder.

At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing the release of a Guarantor pursuant to this Section 11.07.

Contribution.

Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all Guaranteed Obligations to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

Execution of Supplemental Indenture for Future Guarantors.

Each Subsidiary and other Person which is required to become a Guarantor pursuant to Section 4.17 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit D hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article 11 and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary or other Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of

such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

IN WITNESS WHEREOF, the parties have caused this Indenture to be duly executed as of the date first written above.

The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or Additional Interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest (including Additional Interest, if any) on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

Ladies and Gentlemen:

This certificate is delivered to request a transfer of $[ ] principal amount of the 7.5% Senior Notes due 2017 (the “Notes”) of POLYPORE INTERNATIONAL, INC. (such corporation, and its successors and assigns under the Indenture, being herein called the “Company”).

Upon transfer, the Notes would be registered in the name of the new beneficial owner as follows:

Name:

Address:

Taxpayer ID Number:

The undersigned represents and warrants to you that:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Notes, and we are acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes, and we invest in or purchase securities similar to the Notes in the normal course of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment.

2. We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is two years after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Company, (b) pursuant to a registration statement that has been declared effective under the Securities Act, (c) in a transaction complying with the

requirements of Rule 144A under the Securities Act (“Rule 144A”), to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Notes of $250,000, or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant to clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Company and the Trustee.
