“Consolidated Interest Coverage Ratio” means the ratio of Consolidated Cash Flow during the most recent four consecutive full fiscal quarters for which financial statements are available (the “Four-Quarter Period”) ending on or prior to the date of the transaction giving rise to the need to calculate the Consolidated Interest Coverage Ratio (the “Transaction Date”) to Consolidated Interest Expense for the Four-Quarter Period. For purposes of this definition, “Consolidated Cash Flow” and “Consolidated Interest Expense” shall be calculated after giving effect on a pro forma basis for the period of such calculation to:

(1) the incurrence of any Indebtedness or the issuance of any Preferred Stock of the Issuer or any Restricted Subsidiary (and the application of the proceeds thereof) and any repayment of other Indebtedness or redemption of other Preferred Stock (and the application of the proceeds therefrom) (other than the incurrence or repayment of Indebtedness in the ordinary course of business for working capital purposes pursuant to any revolving credit arrangement) 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, repayment, issuance or redemption, as the case may be (and the application of the proceeds thereof), occurred on the first day of the Four-Quarter Period; and

(2) any Investment, acquisition, disposition, merger, consolidation or disposed operation (as determined in accordance with GAAP) (including, without limitation, any acquisition giving rise to the need to make such calculation as a result of the Issuer or any Restricted Subsidiary (including any Person who becomes a Restricted Subsidiary as a result of such acquisition) incurring Acquired Indebtedness and also including any Consolidated Cash Flow (including any pro forma expense and cost reductions calculated on a basis consistent with Regulation S-X under the Exchange Act) associated with any such acquisition) 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 Investment, acquisition, disposition, merger, consolidation or disposed operation (including the incurrence of, or assumption or liability for, any such Acquired Indebtedness) occurred on the first day of the Four-Quarter Period. If since the beginning of such Four-Quarter Period any Person that subsequently became a Restricted Subsidiary or was merged with or into the Issuer or any of its Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation or disposed operation that would have required adjustment pursuant to this definition, then the Consolidated Interest Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, consolidation or disposed operation had occurred at the beginning of the applicable Four-Quarter Period.

If the Issuer or any Restricted Subsidiary directly or indirectly guarantees Indebtedness of a third Person, the preceding sentence shall give effect to the incurrence of such guaranteed Indebtedness as if the Issuer or such Restricted Subsidiary had directly incurred or otherwise assumed such guaranteed Indebtedness.

For purposes of calculating the Consolidated Interest Coverage Ratio prior to the expiration of the first Four-Quarter Period subsequent to the Issue Date, such calculation shall be on the same pro forma basis as the pro forma financial statements that are presented in the Offering Memorandum.

In calculating Consolidated Interest Expense for purposes of determining the denominator (but not the numerator) of this Consolidated Interest Coverage Ratio:

(1) 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 this Indebtedness in effect on the Transaction Date;

(2) if interest on any Indebtedness actually incurred on the Transaction Date 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 rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four-Quarter Period; and

(3) notwithstanding clause (1) or (2) above, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Hedging Obligations, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of these agreements.

“Consolidated Interest Expense” for any period means the sum, without duplication, of the total interest expense minus the interest income of the Issuer and the Restricted Subsidiaries for such period, determined on a consolidated basis in accordance with GAAP and including without duplication,

(1) imputed interest on Capitalized Lease Obligations and Attributable Indebtedness,

(2) commissions, discounts and other fees and charges owed to Persons other than the Issuer or any Restricted Subsidiary with respect to letters of credit securing financial obligations, bankers’ acceptance financing and receivables financings,

(3) the net costs associated with Hedging Obligations,

(4) amortization of debt issuance costs and original issue discount resulting from the issuance of Indebtedness at less than par,

(5) the interest portion of any deferred payment obligations,

(6) all other non-cash interest expense (but excluding any non-cash interest expense attributable to the movement in the mark to market valuation of Hedging Obligations or other derivative instruments pursuant to GAAP),

(7) capitalized interest, and

(8) all cash dividend payments on any series of Disqualified Equity Interests of the Issuer or any Preferred Stock of any Restricted Subsidiary (other than any such Disqualified Equity Interests or any Preferred Stock held by the Issuer or a Wholly-Owned Restricted Subsidiary or to the extent paid in Qualified Equity Interests).

Notwithstanding the preceding, all such amounts relating to the 8% Senior Subordinated Notes and the Floating Rate Notes to be purchased or redeemed in connection with the Transactions and the amortization of debt issuance costs, debt discount or premium and other financing fees and expenses incurred in connection with the Transactions shall be excluded in the calculation of Consolidated Interest Expense to the extent otherwise included therein.

Consolidated Interest Expense shall be calculated after giving effect to Hedging Obligations (including associated costs) but excluding unrealized gains and losses with respect to Hedging Obligations.

“Consolidated Net Income” for any period means the net income (or loss) of the Issuer and the Restricted Subsidiaries for such period determined on a consolidated basis in accordance with GAAP; provided that there shall be excluded from such net income (to the extent otherwise included therein), without duplication:

SECTION 2.02. Execution, Authentication and Denomination; Additional Notes; Exchange Notes.

One Officer of the Issuer (who shall have been duly authorized by all requisite corporate actions) shall sign the Notes for such Issuer by manual or facsimile signature.

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

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 shall authenticate (i) on the Issue Date, Notes for original issue in the aggregate principal amount not to exceed $215,000,000 (the “Initial Notes”), (ii) additional Notes (the “Additional Notes”) in an unlimited amount (so long as not otherwise prohibited by the terms of this Indenture, including, without limitation, Section 4.10) and (iii) Exchange Notes or Private Exchange Notes (x) in exchange for a like principal amount of Initial Notes or (y) in exchange for a like principal amount of Additional Notes in each case upon a written order of the Issuer in the form of a certificate of an Officer of the Issuer (an “Authentication Order”).

In addition, with respect to authentication pursuant to clause (ii) or (iii) of the first sentence of this paragraph, the first such Authentication Order from the Issuer shall be accompanied by an Opinion of Counsel of the Issuer in a form reasonably satisfactory to the Trustee.

All Notes issued under this Indenture shall be treated as a single class for all purposes under this Indenture. The Additional Notes and the Private Exchange Notes shall bear any legend required by applicable law.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate Notes. Unless otherwise provided in the 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 an Agent to deal with the Issuer and Affiliates of the Issuer. The Trustee shall have the right to decline to authenticate and deliver any Notes under this Indenture if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability.

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

The Issuer 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 Issuer of its obligation to maintain or cause to be maintained an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Issuer may act as Registrar or Paying Agent, except that for the purposes of Articles Three and Eight and Sections 4.09 and 4.13, neither the Issuer nor any Affiliate of the Issuer shall act as Paying Agent. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer, upon notice to the Trustee, may have one or more co-registrars and one or more additional paying agents reasonably acceptable to the Trustee. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer initially appoints the Trustee as Registrar and Paying Agent until such time as the Trustee has resigned or a successor has been appointed.

The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee, in advance, of the name and address of any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such.

SECTION 2.04. Paying Agent To Hold Assets in Trust.

The Issuer shall require each Paying Agent other than the Trustee or the Issuer or any Subsidiary to agree in writing that each Paying Agent shall hold in trust for the benefit of Holders or the Trustee all assets held by the Paying Agent for the payment of principal of, or interest on, the Notes (whether such assets have been distributed to it by the Issuer or any other obligor on the Notes), and shall notify the Trustee of any Default by the Issuer (or any other obligor on the Notes) in making any such payment. The Issuer at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon distribution to the Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying Agent shall have no further liability for such assets.

SECTION 2.05. Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least two (2) Business Days prior to 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, which list may be conclusively relied upon by the Trustee.

SECTION 2.06. Transfer and Exchange.

Subject to Sections 2.15 and 2.16, when Notes are presented to the Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Notes surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his or her attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

Without the prior written consent of the Issuer, the Registrar shall not be required to register the transfer of or exchange of any Note (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing, (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Note being redeemed in part, and (iii) beginning at the opening of business on any Record Date and ending on the close of business on the related Interest Payment Date.

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 the Holder of such Global Note (or its agent) in accordance with the applicable legends thereon, and that ownership of a beneficial interest in the Note shall be required to be reflected in a book-entry system.

SECTION 2.07. Replacement Notes.

If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the Trustee’s requirements are met. Such Holder must provide an indemnity bond or other indemnity, sufficient in the judgment of both the Issuer and the Trustee, to protect the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Issuer may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note pursuant to this Section 2.07, including reasonable fees and expenses of counsel and of the Trustee.

Every replacement Note is an additional obligation of the Issuer and of the Guarantors thereof.

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 lost, destroyed or wrongfully taken Notes.

SECTION 2.08. Outstanding Notes.

Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Note does not cease to be outstanding because the Issuer, the Guarantors or any of their respective Affiliates hold the Note (subject to the provisions of Section 2.09).

If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless a Responsible Officer of the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide 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, it ceases to be outstanding and interest ceases to accrue. If on a Redemption Date or the Maturity Date the Trustee or Paying Agent (other than the Issuer or an Affiliate thereof) holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal and interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. 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 Issuer or any of its Affiliates shall be disregarded, 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 a Responsible Officer of the Trustee actually knows are so owned shall be disregarded.

SECTION 2.10. Temporary Notes.

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes. Notwithstanding the foregoing, so long as the Notes are represented by a Global Note, such Global Note may be in typewritten form.

SECTION 2.11. Cancellation.

The Issuer 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 transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent (other than the Issuer or a Subsidiary), and no one else, shall cancel and, at the written direction of the Issuer, shall dispose of all Notes surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. Subject to Section 2.07, the Issuer may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Issuer or any Guarantor shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11.

SECTION 2.12. Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, in any lawful manner. The Issuer may pay the defaulted interest to the persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before any such subsequent special record date, the Issuer shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid.

SECTION 2.13. CUSIP and ISIN Numbers.

The Issuer in issuing the Notes may use “CUSIP” or “ISIN” numbers, and if so, the Trustee shall use the “CUSIP” or “ISIN” numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the “CUSIP” or “ISIN” numbers printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer will promptly notify the Trustee of any change in the “CUSIP” or “ISIN” numbers.

SECTION 2.14. Deposit of Moneys.

Subject to Section 2 of the Notes, prior to 10:00 a.m. New York City time on each Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, the Issuer shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, as the case may be.

SECTION 2.15. Book-Entry Provisions for Global Notes.

(a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in Exhibit B, as applicable.

Members of, or participants in, the Depository (“Participants”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Note, and the Depository may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(b) Transfers of Global Notes shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depository and the provisions of Section 2.16. In addition, Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in Global Notes if (i) the Depository notifies the Issuer that it is unwilling or unable to act as Depository for any Global Note, the Issuer so notifies the Trustee in writing and a successor Depository is not appointed by the Issuer within 90 days of such notice, (ii) the Issuer, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Notes in the form of Physical Notes under this Indenture, or (iii) a Default or Event of Default has occurred and is continuing and the Registrar has received a written request from any owner of a beneficial interest in a Global Note to issue Physical Notes. Upon any issuance of a Physical Note in accordance with this Section 2.15(b) the Trustee is required to register such Physical Note in the name of, and cause the same to be delivered to, such person or persons (or the nominee of any thereof). All such Physical Notes shall bear the applicable legends, if any.

(c) In connection with any transfer or exchange of a portion of the beneficial interest in a Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.15, the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Issuer shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of authorized denominations in an aggregate principal amount equal to the principal amount of the beneficial interest in the Global Note so transferred.

(d) In connection with the transfer of a Global Note as an entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and (i) the Issuer shall execute and (ii) the Trustee shall upon written instructions from the Issuer authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Physical Notes of authorized denominations.

(e) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant to paragraph (b) or (c) of this Section 2.15 shall, except as otherwise provided by Section 2.16, bear the Private Placement Legend.

(f) The Holder of any Global Note may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Notes.

REDEMPTION

SECTION 3.01. Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to Section 5 of the Notes, it shall notify the Trustee in writing of the Redemption Date, the Redemption Price and the principal amount of Notes to be redeemed. The Issuer shall give notice of redemption to the Trustee at least 30 days but not more than 60 days before the Redemption Date, together with such documentation and records as shall enable the Trustee to select the Notes to be redeemed.

SECTION 3.02. Selection of Notes To Be Redeemed.

If less than all of the Notes are to be redeemed at any time pursuant to Section 5 of the Notes, the Trustee will select Notes for redemption as follows:

(x) if the Notes are listed on a national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or

(y) if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate;

provided that, in the case of such redemption pursuant to Section 5(c) of the Notes, the Trustee will select the Notes on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the procedures of the Depository) unless that method is otherwise prohibited.

No Notes of $1,000 or less shall be redeemed in part.

SECTION 3.03. Notice of Redemption.

At least 30 days but not more than 60 days before a Redemption Date, the Issuer shall mail a notice of redemption by first class mail, postage prepaid, to each Holder whose Notes are to be redeemed at its registered address (except that a notice issued in connection with a redemption referred to in Section 8.01 or 8.02 may be more than 60 days before such Redemption Date). At the Issuer’s request delivered at least 5 days before such notice is to be given (unless a shorter period shall be acceptable to the Trustee), the Trustee shall forward the notice of redemption in the Issuer’s name and at the Issuer’s expense. Each notice for redemption shall identify the Notes (including the CUSIP or ISIN number) to be redeemed and shall state:

(1) the Redemption Date;

(2) the Redemption Price and the amount of accrued interest, if any, to be paid;

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

(4) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued interest, if any;

(5) that, unless the Issuer defaults in making the redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Notes redeemed;

(6) 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, and upon surrender and cancellation of such Note, a new Note or Notes in aggregate principal amount equal to the unredeemed portion thereof will be issued;

(7) if fewer than all the Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption; and

(8) the Section of the Notes or this Indenture, as applicable, pursuant to which the Notes are to be redeemed.

The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Except with respect to redemption pursuant to Section 5(c) of the Notes, notices of redemption may not be conditional. Notice of any redemption pursuant to Section 5(c) of the Notes may be given prior to the completion of the related Qualified Equity Offering, and any such redemption or notice may, at the Issuer’s discretion, be subject to the closing of such Qualified Equity Offering.

SECTION 3.04. Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price plus accrued interest, if any. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price (which shall include accrued interest thereon to, but not including, the Redemption Date), but installments of interest, the maturity

of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption unless the Issuer shall have not complied with its obligations pursuant to Section 3.05.

SECTION 3.05. Deposit of Redemption Price.

On or before 10:00 a.m. New York time on the Redemption Date, the Issuer shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued and unpaid interest, if any, of all Notes to be redeemed on that date.

If the Issuer complies with the preceding paragraph, then, unless the Issuer defaults in the payment of such Redemption Price plus accrued interest, if any, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment.

SECTION 3.06. Notes Redeemed in Part.

If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note or Notes in principal amount equal to the unredeemed portion of the original Note or Notes shall be issued in the name of the Holder thereof upon surrender and cancellation of the original Note or Notes.

The provisions of this Article Three notwithstanding, the Issuer may acquire Notes by means other than a redemption, whether pursuant to an issuer tender offer, open market purchase or otherwise, so long as the acquisition does not otherwise violate the terms of this Indenture.

ARTICLE FOUR

COVENANTS

SECTION 4.01. Payment of Notes.

The Issuer shall pay the principal of (and premium, if any) and interest on the Notes in the manner provided in the Notes, the Registration Rights Agreement and this Indenture. An installment of principal of, or interest on, the Notes shall be considered paid on the date it is due if the Trustee or Paying Agent (other than the Issuer or an Affiliate thereof) holds on that date U.S. Legal Tender designated for and sufficient to pay the installment. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Issuer shall pay interest on overdue principal (including, without limitation, post petition interest in a proceeding under any Bankruptcy Law), and overdue interest, to the extent lawful, at the same rate per annum borne by the Notes.

SECTION 4.02. Maintenance of Office or Agency.

The Issuer shall maintain in the Borough of Manhattan, The City of New York, the office or agency required under Section 2.03 (which may be an office of the Trustee or an affiliate of the Trustee or Registrar). The Issuer 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 Issuer 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 address of the Trustee set forth in Section 12.02.

The Issuer 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. The Issuer will 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.

The Issuer hereby initially designates the office or agency of the Trustee located in The Borough of Manhattan, The City of New York, as such office of the Issuer in accordance with Section 2.03.

SECTION 4.03. Corporate Existence.

Except as otherwise permitted by Article Five, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each of its Restricted Subsidiaries in accordance with the respective organizational documents of each such Restricted Subsidiary and the material rights (charter and statutory) and material franchises of the Issuer and each of its Restricted Subsidiaries; provided, however, that the Issuer shall not be required to preserve any such right, franchise or corporate existence with respect to itself or any Restricted Subsidiary if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

SECTION 4.04. Payment of Taxes.

The Issuer and the Guarantors shall, and shall cause each of the Restricted Subsidiaries to, pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all material taxes, assessments and governmental charges levied or imposed upon it or any of the Restricted Subsidiaries or upon the income, profits or property of it or any of the Restricted Subsidiaries and (b) all lawful claims for labor, materials and supplies which, in each case, if unpaid, might by law become a material liability or Lien upon the property of it or any of the Restricted Subsidiaries; provided, however, that the Issuer and the Guarantors shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount the applicability or validity is being contested in good faith by appropriate actions and for which appropriate provision has been made.

SECTION 4.05. Suspension of Covenants.

(a) During any period of time that (1) the Notes have Investment Grade Ratings from both Rating Agencies and (2) no Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (1) and (2) being collectively referred to as a “Covenant Suspension Event” and the date thereof being referred to as the “Suspension Date”) then, Sections 4.10, 4.11, 4.13, 4.14, 4.15, 4.17 and 5.01(a)(3) (collectively, the “Suspended Covenants”) will not be applicable to the Notes. Following any Suspension Date and prior to a corresponding Reversion Date, the Issuer may not designate any Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.19. In the event that the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating, then the Issuer and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. The period of time between the Suspension Date and the Reversion Date is referred to as the “Suspension Period.” Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Net Available Proceeds shall be reset to zero.

(b) Notwithstanding the foregoing, in the event of any such reinstatement, no action taken or omitted to be taken by the Issuer or any of its Restricted Subsidiaries prior to such reinstatement will give rise to a Default or Event of Default under this Indenture; provided that (1) with respect to Restricted Payments made after such reinstatement, the amount of Restricted Payments made will be calculated as though the Section 4.11 had been in effect prior to, but not during, the Suspension Period (and, for avoidance of doubt, all Consolidated Net Income and other amounts attributable to the Suspension Period that would otherwise increase the amount of the Restricted Payments Basket shall be excluded in determining the amount of the Restricted Payments Basket following the Reversion Date); and (2) all Indebtedness incurred, or Disqualified Equity Interests issued, during the Suspension Period will be classified to have been incurred or issued pursuant to Section 4.10(b)(3).

SECTION 4.06. Compliance Certificate; Notice of Default.

(a) The Issuer shall deliver to the Trustee, within 120 days after the close of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Issuer and its Subsidiaries has been made under the supervision of the signing Officers with a view to determining whether the Issuer and the Guarantors have kept, observed, performed and fulfilled their obligations under this Indenture and further stating, as to each such Officer signing such certificate, that to the best of such Officer’s knowledge, the Issuer and the Guarantors during such preceding fiscal year has kept, observed, performed and fulfilled each and every such covenant and no Default occurred during such year and at the date of such certificate there is no Default that has occurred and is continuing or, if such signers do know of such Default, the certificate shall specify such Default and what action, if any, the Issuer is taking or proposes to take with respect thereto. The Officers’ Certificate shall also notify the Trustee should the Issuer elect to change the manner in which it fixes the fiscal year end.

(b) The Issuer shall deliver to the Trustee, upon any Officer of the Issuer becoming aware of the occurrence of any Default, an Officers’ Certificate specifying the Default and what action, if any, the Issuer is taking or proposes to take with respect thereto.

SECTION 4.07. Business Activities.

The Issuer will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business.

SECTION 4.08. Waiver of Stay, Extension or Usury Laws.

The Issuer and each Guarantor covenants (to the extent permitted by applicable law) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive such Issuer or such Guarantor from paying all or any portion of the principal of and/or interest on the Notes, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and (to the extent permitted by applicable law) each hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 4.09. Change of Control.

Upon the occurrence of any Change of Control, unless the Issuer has previously or concurrently mailed a redemption notice with respect to all the outstanding Notes pursuant to Section 5 of the Notes, each Holder will have the right to require that the Issuer purchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder’s Notes pursuant to a Change of Control Offer (the “Change of Control Offer”). In the Change of Control Offer, the Issuer will offer to pay an amount in cash (the “Change of Control Purchase Price”) equal to 101% of the aggregate principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase. Within 30 days following any Change of Control, the Issuer will mail, or cause to be mailed, a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to purchase Notes on the date (the “Change of Control Payment Date”) specified in such notice, which date shall be a Business Day no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures described below. Such notice shall state:

(1) that the Change of Control Offer is being made pursuant to this Section 4.09 and that all Notes tendered and not withdrawn will be accepted for payment;

(2) the purchase price (including the amount of accrued interest) and the Change of Control Payment Date;

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

(4) that, unless the Issuer defaults in making payment therefor, any Note accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have a Note purchased pursuant to a Change of Control Offer will 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;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the second Business Day prior to the Change of Control Payment Date, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(7) that Holders whose Notes are purchased only in part will be issued new Notes in a principal amount equal to the unpurchased portion of the Notes surrendered (equal to $1,000 or an integral multiple of $1,000); and

(8) the circumstances and relevant facts regarding such Change of Control.

On or before the Change of Control Payment Date, the Issuer will, to the extent lawful:

(i) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;

(ii) deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Change of Control Purchase Price in respect of all Notes or portions thereof so tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Issuer.

The Paying Agent will promptly mail to each Holder of Notes so tendered the Change of Control Purchase Price for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $1,000 or an integral multiple of $1,000.

The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The Issuer will 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 Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer.

Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

The Issuer shall cause the Change of Control Offer to remain open for at least 20 Business Days or for such longer period as may be required by law. The Issuer will comply with applicable tender offer rules, including 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 a Change of Control Offer. To the extent the provisions of any applicable securities laws or regulations conflict with the provisions of this Section 4.09, the Issuer

will not be deemed to have breached their obligations under this Section 4.09 by virtue of complying with such laws or regulations.

SECTION 4.10. Limitations on Additional Indebtedness.

(b) the Consolidated Interest Coverage Ratio of the Issuer and the Restricted Subsidiaries is equal to or greater than immediately prior to such transaction;

In addition, for purposes of determining any particular amount of Indebtedness under this Section 4.10, guarantees, Liens or letter of credit obligations supporting Indebtedness otherwise included in the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness.

(c) the aggregate amount by which Indebtedness (other than any Subordinated Indebtedness) incurred by the Issuer or any Restricted Subsidiary subsequent to the Issue Date is reduced on the Issuer’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Issuer) into Qualified Equity Interests (less the amount of any cash, or the fair value of assets, distributed by the Issuer or any Restricted Subsidiary upon such conversion or exchange), plus

(d) in the case of the disposition or repayment of or return on any Investment that was treated as a Restricted Payment made after the Issue Date, an amount (to the extent not included in the computation of Consolidated Net Income) equal to 100% of the aggregate amount received by the Issuer or any Restricted Subsidiary in cash or other property (valued at the Fair Market Value thereof) as the return of capital with respect to such Investment, less the cost of the disposition of such Investment and net of taxes, plus

provided that (a) in the case of any Restricted Payment pursuant to clauses (3), (8), (9) or (10) above, no Default shall have occurred and be continuing or occur as a consequence thereof and (b) to the extent the issuance and sale of Qualified Equity Interests or contributions to the common equity capital of the Issuer are used to make a payment pursuant to clause (2) or (3) above, such issuance and sale or contribution shall not increase the Restricted Payments Basket.

SECTION 4.12. Limitations on Liens.

The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien of any nature whatsoever (other than Permitted Liens) against any assets of the Issuer or any Restricted Subsidiary (including Equity Interests of a Restricted Subsidiary), securing any

Indebtedness, whether owned at the Issue Date or thereafter acquired, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom, unless contemporaneously therewith:

(1) in the case of any Lien securing an obligation that ranks pari passu with the Notes or a Note Guarantee, effective provision is made to secure the Notes or such Note Guarantee, as the case may be, at least equally and ratably with or prior to such obligation with a Lien on the same assets of the Issuer or such Restricted Subsidiary, as the case may be; and

(2) in the case of any Lien securing an obligation that is subordinated in right of payment to the Notes or a Note Guarantee, effective provision is made to secure the Notes or such Note Guarantee, as the case may be, with a Lien on the same assets of the Issuer or such Restricted Subsidiary, as the case may be, that is prior to the Lien securing such subordinated obligation,

in each case, for so long as such obligation is secured by such Lien.

SECTION 4.13. Limitations on Asset Sales.

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets included in such Asset Sale; and

(2) at least 75% of the total consideration received in such Asset Sale consists of cash or Cash Equivalents.

(b) For purposes of clause (2) of Section 4.13(a), the following shall be deemed to be cash:

(1) the amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness) of the Issuer or such Restricted Subsidiary that is expressly assumed by the transferee in such Asset Sale and with respect to which the Issuer or such Restricted Subsidiary, as the case may be, is unconditionally released by the holder of such Indebtedness,

(2) the amount of any securities received from such transferee that are within 365 days converted by the Issuer or such Restricted Subsidiary to cash (to the extent of the cash actually so received), and

(3) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or (iii) a combination of (i) and (ii).

(c) If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary of the Issuer, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.13.

(d) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom to:

(1) repay obligations under the Credit Agreement, and in the case of any such repayment under any revolving credit facility, effect a permanent reduction in the availability under such revolving credit facility;

(2) repay any Indebtedness which was secured by the assets sold in such Asset Sale;

(3) repay any Pari Passu Indebtedness that is secured by a Lien (to the extent of the value of the assets (excluding any assets also pledged to secure the Notes or any Note Guarantee pursuant to clause (1) of Section 4.12) secured by such Lien), which Lien is permitted by this Indenture;

(4) repay any Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Issuer or another Restricted Subsidiary; and/or

(5) (A) invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities) to be used by the Issuer or any Restricted Subsidiary in a Permitted Business, (B) acquire Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition, (C) make capital expenditures or (D) a combination of (A), (B) and/or (C);

provided that the Issuer and its Restricted Subsidiaries will be deemed to have complied with the provisions described in clause (5) of this paragraph if and to the extent that, within 365 days after the Asset Sale that generated the Net Available Proceeds, the Issuer or such Restricted Subsidiary has entered into and not abandoned or rejected a binding agreement to effect the provisions of clause (5) of this paragraph, and the Net Available Proceeds are applied as described in clause (5) of this paragraph within 180 days after the end of such 365-day period; provided that if any Net Available Proceeds are not so applied, then such Net Available Proceeds shall constitute Excess Proceeds (as defined below) on such 180th day.

The amount of Net Available Proceeds not applied or invested as provided in this paragraph will constitute “Excess Proceeds.”

(e) When the aggregate amount of Excess Proceeds equals or exceeds $25.0 million, the Issuer will be required to make within 10 Business Days thereof, an offer to purchase from all Holders and, if applicable, redeem (or make an offer to do so) any Pari Passu Indebtedness of the Issuer the provisions of which require the Issuer to redeem such Indebtedness with the proceeds from any Asset Sales (or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows:

(1) the Issuer will (a) make an offer to purchase (a “Net Proceeds Offer”) to all Holders in accordance with the procedures set forth in this Indenture, and (b) redeem (or make an offer to do so) any such other Pari Passu Indebtedness, pro rata in proportion to the respective principal amounts of the Notes and such other Indebtedness required to be redeemed, the maximum principal amount of Notes and Pari Passu Indebtedness that may be redeemed out of the amount (the “Payment Amount”) of such Excess Proceeds;

(2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the “Offered Price”), in accordance with the procedures set forth in this Indenture and the redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness Price”) shall be as set forth in the related documentation governing such Indebtedness;

(3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the pro rata portion of the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a pro rata basis; and

(4) upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

(f) To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the aggregate Pari Passu Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a “Net Proceeds Deficiency”), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for general corporate purposes, subject to the provisions of this Indenture.

(g) Pending the final application of any Net Available Proceeds pursuant to this covenant, the holder of such Net Available Proceeds may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Available Proceeds in Cash Equivalents.

(h) Upon the commencement of a Net Proceeds Offer, the Issuer shall send, by first class mail, a notice to the Trustee and to each Holder at is registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Notes pursuant to the Net Proceeds Offer. Any Net Proceeds Offer shall be made to all Holders. The notice, which shall govern the terms of the Net Proceeds Offer, shall state:

(1) that the Net Proceeds Offer is being made pursuant to this Section;

(2) the Payment Amount, the Offered Price, and the date on which Notes tendered and accepted for payment shall be purchased, which date shall be at least 30 days and not later than 60 days from the date such notices is mailed (the “Net Proceeds Payment Date”);

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

(4) that, unless the Issuer defaults in making such payment, any Notes accepted for payment pursuant to the Net Proceeds Offer shall cease to accrue interest on and after the Net Proceeds Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to any Net Proceeds Offer shall be required to surrender the Notes, 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 Issuer, a depository, if appointed by the Issuer, or the Paying Agent at the address specified in the notice at least three days before the Net Proceeds Payment Date;

(6) that Holders shall be entitled to withdraw their election if the Issuer, the Depository or the Paying Agent, as the case may be, receives, not later than the Net Proceeds Payment Date, a notice 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;

(7) that if the aggregate principal amount of Notes surrendered by Holders exceeds the Payment Amount, the Issuer shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $1,000, or integral multiples of $1,000, shall be purchased); and

(8) 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).

(i) On the Net Proceeds Payment Date, the Issuer shall, to the extent lawful: (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Net Proceeds Offer, subject to pro ration if the aggregate Notes tendered exceed the Payment Amount allocable to the Notes; (2) deposit with the Paying Agent U.S. Legal Tender equal to the lesser of the Payment Amount allocable to the Notes and the amount sufficient to pay the Offered Price in respect of all Notes or portions thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being repurchased by the Issuer. The Issuer shall publicly announce the results of the Net Proceeds Offer on the Net Proceeds Payment Date.

(j) The Paying Agent shall promptly mail to each Holder of Notes so tendered the Offered Price for such Notes, and the Trustee shall promptly authenticate pursuant to an Authentication Order and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unrepurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in principal amount of $1,000 or an integral multiple of $1,000. However, if the Net Proceeds Payment 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.

(k) The Issuer will comply with applicable tender offer rules, including the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase 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 4.13, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.13 by virtue of this compliance.

SECTION 4.14. Limitations on Transactions with Affiliates.

(a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate involving aggregate payments or consideration in excess of $2.5 million (an “Affiliate Transaction”), unless:

(1) such Affiliate Transaction is on terms that are not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction at such time on an arm’s-length basis by the Issuer or that Restricted Subsidiary from a Person that is not an Affiliate of the Issuer or that Restricted Subsidiary; and

(2) the Issuer delivers to the Trustee:

(x) with respect to any Affiliate Transaction involving aggregate value in excess of $10.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by the Board of Directors approving such Affiliate Transaction; and

(y) with respect to any Affiliate Transaction involving aggregate value of $35.0 million or more, the certificates described in the preceding clause (x) and a written opinion as to the fairness of such Affiliate Transaction to the Issuer or such Restricted Subsidiary from a financial point of view issued by an Independent Financial Advisor.

(b) The foregoing restrictions shall not apply to:

(1) transactions exclusively between or among (a) the Issuer and one or more Restricted Subsidiaries or (b) Restricted Subsidiaries; provided, in each case, that no Affiliate of the Issuer (other than another Restricted Subsidiary) owns Equity Interests of any such Restricted Subsidiary;

(2) reasonable director, officer and employee compensation (including bonuses) and other benefits (including retirement, health, stock option and other benefit plans) and indemnification and employment arrangements, in each case approved by the Board of Directors, and payments to Parent or on behalf of Parent to pay such amounts incurred by Parent;

(3) payments by the Issuer and/or one or more Subsidiaries to any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes, to be used by such Person to

pay taxes, and which payments by the Issuer and such Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis;

(4) payments by the Issuer to or on behalf of Parent in an amount sufficient to pay out-of-pocket legal, accounting and filing costs, franchise taxes, general operating and overhead expenses and other fees required to maintain the corporate existence of Parent or that are otherwise attributable to the ownership or operation of the Issuer and fees and expenses related to any unsuccessful securities offering of Parent actually incurred by Parent;

The Issuer will not, and will not permit any Restricted Subsidiary 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 to:

(a) pay dividends or make any other distributions on or in respect of its Equity Interests;

(b) make loans or advances or pay any Indebtedness or other obligation owed to the Issuer or any other Restricted Subsidiary; or

except for:

(1) encumbrances or restrictions existing under or by reason of applicable law;

(2) encumbrances or restrictions existing under this Indenture, the Notes and the Note Guarantees;

(3) non-assignment provisions of any contract or any lease or license entered into in the ordinary course of business;

(4) encumbrances or restrictions existing under agreements existing on the date of this Indenture (including, without limitation, the Credit Facilities) as in effect on that date;

(5) restrictions on the transfer of assets subject to any Lien permitted under this Indenture imposed by the holder of such Lien;

(6) restrictions on the transfer of assets imposed under any agreement to sell such assets permitted under this Indenture to any Person pending the closing of such sale;

(7) 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;

(8) any other agreement governing Indebtedness entered into after the Issue Date that contains encumbrances and restrictions that are no more materially restrictive, taken as a whole, than those in effect on the Issue Date pursuant to agreements in effect on the Issue Date;

(9) customary provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements and other similar agreements entered into in the ordinary course of business that restrict the transfer of ownership interests in such partnership, limited liability company, joint venture or similar Person;

(10) Purchase Money Indebtedness and Capitalized Lease Obligations incurred in compliance with Section 4.10 that impose restrictions of the nature described in clause (c) above on the assets acquired;

(12) any encumbrances or restrictions imposed by any amendments or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (10) above; provided that such amendments or refinancings are, in the good faith judgment of the Issuer’s Board of Directors, no more materially restrictive taken as a whole with respect to such encumbrances and restrictions than those prior to such amendment or refinancing.

SECTION 4.16. Additional Note Guarantees.

(a) If, after the Issue Date, (x) the Issuer or any Restricted Subsidiary shall acquire or create another Subsidiary (other than an Excluded Subsidiary), (y) any Unrestricted Subsidiary is designated a Restricted Subsidiary (other than an Excluded Subsidiary) or (z) the Issuer otherwise elects to have any Restricted Subsidiary become a Guarantor, then, in each such case, the Issuer shall cause such Restricted Subsidiary to:

(1) execute and deliver to the Trustee a supplemental indenture in form and substance reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and this Indenture to the same extent as the Note Guarantees; and

(2) deliver to the Trustee one or more Opinions of Counsel that such supplemental indenture (a) has been duly authorized, executed and delivered by such Restricted Subsidiary and (b) constitutes a valid and legally binding obligation of such Restricted Subsidiary in accordance with its terms (provided, that such Opinion of Counsel shall not be given in connection with the execution of the supplemental indenture on the Issue Date).

Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture.

(b) Notwithstanding Section 4.16(a), a Subsidiary Guarantor will be automatically and unconditionally released and discharged from its obligations under its Note Guarantee, this Indenture and the Registration Rights Agreement under the circumstances set forth in Section 11.05(a).

SECTION 4.17. Limitation on Layering Indebtedness.

The Issuer will not, and will not permit any Guarantor to, directly or indirectly, incur any Indebtedness that is or purports to be by its terms (or by the terms of any agreement governing such Indebtedness) subordinated in right of payment to any other Indebtedness of the Issuer or of such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate in right of payment to the Notes or the Note Guarantee of such Guarantor, to the same extent and in the same manner as such Indebtedness is subordinated in right of payment to such other Indebtedness of the Issuer or such Guarantor, as the case may be.

For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Issuer or any Guarantor solely by virtue of being unsecured or secured by a junior priority lien or by virtue of the fact that the holders of such Indebtedness have entered into intercreditor agreements or other arrangements giving one or more of such holders priority over the other holders in the collateral held by them, including intercreditor agreements that contain customary provisions requiring turnover by holders of junior prior liens of proceeds of collateral in the event that the security interests in favor of the holders of the senior priority in such intended collateral are not perfected or invalidated and similar customary provisions protecting the holders of senior priority liens.

SECTION 4.18. Reports to Holders.

Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer or Parent will furnish to the Holders of Notes, or file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system), within 15 days of the time periods that would be applicable to the Issuer or Parent, as applicable, if it were subject to Section 13(a) or 15(d) of the Exchange Act as a non-accelerated filer:

(1) 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 Issuer or Parent, as applicable, were required to file these Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Issuer’s or Parent’s, as applicable, certified independent accountants; and

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

In addition, whether or not required by the SEC, the Issuer will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within 15 days of the time periods specified in the SEC’s rules and regulations for a non-accelerated filer required to file reports under Section 13(a) or 15(d) of the Exchange Act (unless the SEC will not accept the filing) and make the information available to prospective investors upon request. The Issuer agrees that it will not take any action (including, following the Registered Exchange Offer (as defined in the Registration Rights Agreement entered into on the Issue Date), terminating its registration under Section 15(d) of the Exchange Act) for the purpose of causing the SEC not to accept such filings. The Issuer and the Guarantors have agreed that, for so long as any Notes remain outstanding, the Issuer will furnish to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

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 required by the Registration Rights Agreement by (1) the filing with the SEC of the exchange offer registration statement or shelf registration statement (or any other similar registration statement), and any amendments thereto, with such financial information

that satisfies Regulation S-X of the Securities Act or (2) by posting publicly on its website, within 15 days of the time periods after the Issuer or Parent would have been required to file annual and interim reports with the SEC as a non-accelerated filer, the information (including a “Management’s discussion and analysis of financial condition and results of operations” section) that would be required to be included in such reports, subject to exceptions consistent with the presentation of financial information in the Offering Memorandum.

Neither the Issuer nor any Guarantor shall provide information to any Person or the public not otherwise authorized to receive such information relative to performance requirements or performance contracts when such information requires access to information classified pursuant to Executive Order 12356, April 2, 1982 (47 Federal Register 14874, April 6, 1982), or successor or predecessor orders, or the Atomic Energy Act of 1954 (as amended). Neither the Issuer nor any Guarantor shall be required to acknowledge to any Person or the public not otherwise authorized to receive such information the existence or non-existence of work under special access or compartmented programs. Notwithstanding the foregoing, should the Issuer or any Guarantor withhold information permitted pursuant to this paragraph, such entity shall nonetheless use its commercially reasonable efforts to comply with the rules and regulations of the SEC relating to the information to be provided pursuant to the first paragraph above, but shall not be obligated to make disclosures required by the rules and regulations of the SEC to the extent such disclosures would conflict with the two preceding sentences.

SECTION 4.19. Limitations on Designation of Unrestricted Subsidiaries.

(a) The Issuer may designate any Subsidiary of the Issuer as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, an Investment in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

(b) No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless such Subsidiary:

(1) has no Indebtedness other than Non-Recourse Debt;

(2) is not party to any agreement, contract, arrangement or understanding with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are no less favorable to the Issuer or the Restricted Subsidiary, taken as a whole, than those that might be obtained at the time from Persons who are not Affiliates;

(3) is a Person with respect to which neither the Issuer nor any Restricted Subsidiary has any direct or indirect obligation (a) to subscribe for additional Equity Interests or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results; and

(4) has not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Issuer or any Restricted Subsidiary, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary.

(c) If, at any time, any Unrestricted Subsidiary fails to meet the requirements of Section 4.19(a) and (b) as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of such date and, if the Indebtedness is not permitted to be incurred under Section 4.10 or the Lien is not permitted under the covenant described under Section 4.12, the Issuer shall be in default of the applicable covenant.

(d) The Issuer may designate an Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if:

(1) no Default shall have occurred and be continuing at the time of and after giving effect to such Redesignation; and

(2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture.

(e) All Designations and Redesignations must be evidenced by resolutions of the Board of Directors of the Issuer, delivered to the Trustee certifying compliance with the foregoing provisions.

SECTION 4.20. Additional Interest Notice.

In the event that the Issuer is required to pay Additional Interest Holders of the Notes pursuant to the Registration Rights Agreement, the Issuer will provide written notice (an “Additional Interest Notice”) to the Trustee of its obligation to pay Additional Interest no later than fifteen days prior to the proposed payment date for the Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Issuer on such payment date. The Trustee shall not at any time be under any duty or responsibility to any Holder of Notes to determine the Additional Interest, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

(b) Parent will not, directly or indirectly, in a single transaction or a series of related transactions, consolidate or merge with or into another Person, or sell, lease, transfer, convey or otherwise dispose of or assign all or substantially all of the assets of Parent and its Subsidiaries (taken as a whole) unless:

(1) either:

(a) Parent will be the surviving or continuing Person; or

(b) the Person formed by or surviving such consolidation or merger or to which such sale, lease, conveyance or other disposition shall be made (collectively, the “Parent Successor”) is a corporation, limited liability company or limited partnership organized and existing under the laws of any State of the United States of America or the District of Columbia, and the Parent Successor expressly assumes, by supplemental indenture in form and substance reasonably satisfactory to the Trustee, all of the obligations of Parent under its Note Guarantee, this Indenture and the Registration Rights Agreement; and

Each of the following is an “Event of Default”:

(1) failure by the Issuer to pay interest on any of the Notes when it becomes due and payable and the continuance of any such failure for 30 days;

(2) failure by the Issuer to pay the principal on any of the Notes when it becomes due and payable, whether at stated maturity, upon redemption, upon purchase, upon acceleration or otherwise;

(3) failure by the Issuer to comply with Section 5.01 or in respect of its obligations to make a Change of Control Offer pursuant to Section 4.09;

(4) failure by the Issuer to comply with any other agreement or covenant in this Indenture and continuance of this failure for 60 days after notice of the failure has been given to the Issuer by the Trustee or by the Holders of at least 25% of the aggregate principal amount of the Notes then outstanding;

(5) default under any mortgage, indenture or other instrument or agreement under which there may be issued or by which there may be secured or evidenced Indebtedness of the Issuer or any Restricted Subsidiary, whether such Indebtedness now exists or is incurred after the Issue Date, which default:

(a) is caused by a failure to pay at final maturity, principal on such Indebtedness within the applicable express grace period and any extensions thereof,

(b) results in the acceleration of such Indebtedness prior to its express final maturity or

(c) results in the commencement of judicial proceedings to foreclose upon, or to exercise remedies under applicable law or applicable security documents to take ownership of, the assets securing such Indebtedness, and

in each case, the principal amount of such Indebtedness, together with any other Indebtedness with respect to which an event described in clause (a), (b) or (c) has occurred and is continuing, aggregates $35.0 million or more;

(6) one or more judgments or orders that exceed $35.0 million in the aggregate (net of amounts covered by insurance or bonded) for the payment of money have been entered by a court or courts of competent jurisdiction against the Issuer or any Restricted Subsidiary and such judgment or judgments have not been satisfied, stayed, annulled or rescinded within 60 days of being entered;

(7) the Issuer or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(a) commences a voluntary case,

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

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

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

(a) is for relief against the Issuer or any Significant Subsidiary as debtor in an involuntary case,

(b) appoints a Custodian of the Issuer or any Significant Subsidiary or a Custodian for all or substantially all of the assets of the Issuer or any Significant Subsidiary, or

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

(9) any Note Guarantee of any Significant Subsidiary ceases to be in full force and effect (other than in accordance with the terms of such Note Guarantee and this Indenture) or is declared null and void and unenforceable or found to be invalid or any Guarantor denies its liability under its Note Guarantee (other than by reason of release of a Guarantor from its Note Guarantee in accordance with the terms of this Indenture).

SECTION 6.02. Acceleration.

If an Event of Default specified in Section 6.01(7) or (8) with respect to the Issuer occurs, all outstanding Notes shall become due and payable without any further action or notice. If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8) with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable immediately. Upon such declaration of acceleration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable immediately; provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may rescind and annul such acceleration:

(1) if the rescission would not conflict with any judgment or decree;

(2) if all existing Defaults have been cured or waived except nonpayment of principal and interest that has become due solely because of this acceleration;

(3) 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;

(4) if the Issuer has paid to the Trustee its reasonable compensation and reimbursed the Trustee of its expenses, disbursements and advances; and

(5) in the event of a cure or waiver of a Default of the type set forth in Section 6.01(7) or (8), the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 6.03. Other Remedies.

If a Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or interest on, the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon a Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Past Defaults.

Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority in principal amount of the outstanding Notes (which may include consents obtained in connection with a tender offer or exchange offer of Notes) by notice to the Trustee may waive an existing Default and its consequences, except a Default in the payment of principal of, or interest on, any Note as specified in Section 6.01(1) or (2). The Issuer shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of Holders have consented to such waiver and attaching copies of such consents. When a Default is waived, it is cured and ceases.

SECTION 6.05. Control by Majority.

The Holders of not less than a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder, or that may involve the Trustee in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

In the event the Trustee takes any action or follows any direction pursuant to this Indenture, the Trustee shall be entitled to indemnification reasonably satisfactory to the Trustee against any loss or expense caused by taking such action or following such direction.

SECTION 6.06. Limitation on Suits.

No Holder will have any right to institute any proceeding with respect to this Indenture or for any remedy thereunder, unless the Trustee:

(1) has failed to act for a period of 60 days after receiving written notice of a continuing Event of Default by such Holder and a request to act by Holders of at least 25% in aggregate principal amount of Notes outstanding;

(2) has been offered indemnity satisfactory to it in its reasonable judgment; and

(3) has not received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request.

However, such limitations do not apply to a suit instituted by a Holder of any Note for enforcement of payment of the principal of or interest on such Note on or after the due date therefor.

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

SECTION 6.07. Rights of Holders To Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, and interest on, a Note, on or after the respective due dates therefor, 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 the Holder.

SECTION 6.08. Collection Suit by Trustee.

If a Default in payment of principal or interest specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount of principal and accrued interest and fees remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Notes and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

The Trustee may 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 compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relating to the Issuer, their creditors or their property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings 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 agent and counsel, and any other amounts due the Trustee under Section 7.07. 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 thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee shall be entitled to participate as a member of any official committee of creditors in the matters as it deems necessary or advisable.

SECTION 6.10. Priorities.

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

First: to the Trustee for amounts due under Section 7.07;

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

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

Fourth: to the Issuer or, if applicable, the Guarantors, as their respective interests may appear.

The Trustee, upon prior notice to the Issuer, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party

litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes.

TRUSTEE

SECTION 7.01. Duties of Trustee.

(a) If a 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.

However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(c) Notwithstanding anything to the contrary herein, the Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(2) The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts.

(3) The Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

(d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or to take or omit to take any action under this Indenture or take any action at the request or direction of Holders if it shall have reasonable grounds for believing that repayment of such funds is not assured to it.

(e) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to this Section 7.01.

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

SECTION 7.03. 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 Issuer, its Subsidiaries or its respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. 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 Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer in this Indenture or any document issued in connection with the sale of Notes or any statement in the Notes other than the Trustee’s certificate of authentication. The Trustee makes no representations with respect to the effectiveness or adequacy of this Indenture.

SECTION 7.05. Notice of Default.

If a Default occurs and is continuing and the Trustee receives actual notice of such Default, the Trustee shall mail to each Holder notice of the uncured Default within 30 days after such Default occurs. Except in the case of a Default in payment of principal of, or interest on, any Note, including an accelerated payment and the failure to make a payment on the Change of Control Payment Date pursuant to a Change of Control Offer or the Net Proceeds Payment Date pursuant to a Net Proceeds Offer, or a Default in complying with the provisions of Article Five, the Trustee may withhold the notice if and so long as the Board of Directors, the executive committee, or a trust committee of directors and/or Responsible Officers, of the Trustee in good faith determines that withholding the notice is in the interest of the Holders.

SECTION 7.06. Reports by Trustee to Holders.

Within 60 days after each January 1, beginning with January 1, 2012, the Trustee shall, to the extent that any of the events described in Trust Indenture Act § 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with Trust Indenture Act § 313(a). The Trustee also shall comply with Trust Indenture Act §§ 313(b), 313(c) and 313(d).

A copy of each report at the time of its mailing to Holders shall be mailed to the Issuer and filed with the SEC and each securities exchange, if any, on which the Notes are listed.

The Issuer shall notify the Trustee if the Notes become listed on any securities exchange or of any delisting thereof and the Trustee shall comply with Trust Indenture Act § 313(d).

SECTION 7.07. Compensation and Indemnity.

The Issuer shall pay to the Trustee from time to time such compensation as the Issuer and the Trustee shall from time to time agree in writing for its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all

reasonable disbursements, expenses and advances (including reasonable fees and expenses of counsel) incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s negligence, bad faith or willful misconduct. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel.

The Issuer shall indemnify each of the Trustee or any predecessor Trustee and its agents for, and hold them harmless against, any and all loss, damage, claims including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), liability or expense incurred by them except for such actions to the extent caused by any negligence, bad faith or willful misconduct on their part, arising out of or in connection with the acceptance or administration of this trust including the reasonable costs and expenses of defending themselves against or investigating any claim or liability in connection with the exercise or performance of any of the Trustee’s rights, powers or duties hereunder. The Trustee shall notify the Issuer promptly of any claim asserted against the Trustee or any of its agents for which it may seek indemnity. The Issuer may, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), defend the claim and the Trustee shall cooperate in the defense. The Trustee and its agents subject to the claim may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel; provided, however, that the Issuer will not be required to pay such fees and expenses if, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), it assumes the Trustee’s defense and there is no conflict of interest between the Issuer and the Trustee and its agents subject to the claim in connection with such defense as reasonably determined by the Trustee. The Issuer need not pay for any settlement made without its written consent (which shall not be unreasonably withheld). The Issuer need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its negligence, bad faith or willful misconduct.

To secure the Issuer’s payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes against all money or property held or collected by the Trustee, in its capacity as Trustee, except money or property held in trust to pay principal and interest on particular Notes.

When the Trustee incurs expenses or renders services after a Default specified in Section 6.01(7) or (8) occurs, such expenses and the compensation for such services shall be paid to the extent allowed under any Bankruptcy Law.

Notwithstanding any other provision in this Indenture, the foregoing provisions of this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the appointment of a successor Trustee.

SECTION 7.08. Replacement of Trustee.

The Trustee may resign at any time by so notifying the Issuer in writing. The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee by so notifying the Issuer and the Trustee and may appoint a successor Trustee. The Issuer may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10;

(2) the Trustee is adjudged a bankrupt or an insolvent;

(3) a receiver or other public officer takes charge of the Trustee or its property; or

(4) 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 Issuer shall notify each Holder of such event and 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 Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer, after payment of all sums then owing to the Trustee

pursuant to Section 7.07, all property held by it as Trustee to the successor Trustee, subject to the Lien provided in Section 7.07, 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. A successor Trustee shall mail notice of its succession to each Holder.

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

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

SECTION 7.09. Successor Trustee by Merger, Etc.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee; provided that such corporation shall be otherwise qualified and eligible under this Article Seven.

SECTION 7.10. Eligibility; Disqualification.

This Indenture shall always have a Trustee who satisfies the requirement of Trust Indenture Act §§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a combined capital and surplus of at least $150,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture Act § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer are outstanding, if the requirements for such exclusion set forth in Trust Indenture Act § 310(b)(1) are met. The provisions of Trust Indenture Act § 310 shall apply to the Issuer and any other obligor of the Notes.

SECTION 7.11. Preferential Collection of Claims Against the Issuer.

The Trustee, in its capacity as Trustee hereunder, shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to the extent indicated.

(2) (a) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption within one year or (iii) have been called for redemption pursuant to Section 5 of the Notes and the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of Holders, U.S. Legal Tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Indebtedness (including all principal and accrued interest and premium, if any) on the Notes not theretofore delivered to the Trustee for cancellation,

In the case of clause (2) of this Section 8.01, and subject to the next sentence and notwithstanding the foregoing paragraph, the Issuer’s obligations in Sections 2.05, 2.06, 2.07, 2.08, 2.10, 4.01, 4.02, 4.03 (as to legal existence of the Issuer only), 7.07, 8.05 and 8.06 shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.08. After the Notes are no longer outstanding, the Issuer’s obligations in Sections 7.07, 8.05 and 8.06 shall survive.

After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

SECTION 8.02. Legal Defeasance and Covenant Defeasance.

(a) The Issuer may, at its option and at any time, elect to have either paragraph (b) or (c) below be applied to the outstanding Notes upon compliance with the conditions set forth in Section 8.03.

(b) Upon the Issuer’s exercise under Section 8.02(a) hereof of the option applicable to this Section 8.02(b), the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03, be deemed to have been discharged from their 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 Issuer and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and the Note Guarantees, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.04 hereof and the other Sections of this Indenture referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Notes and this Indenture and the Guarantors shall be deemed to have satisfied all of their obligations under the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(i) 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 8.04, payments in respect of the principal of , premium, if any, and interest on such Notes when such payments are due;

Subject to compliance with this Article Eight, the Issuer may exercise its option under this Section 8.02(b) notwithstanding the prior exercise of its option under Section 8.02(c) hereof.

(c) Upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03 hereof, be released from their respective obligations under the covenants contained in Sections 4.03 (other than with respect to the legal existence of the Issuer), 4.04, 4.07 and 4.09 through 4.19, clause (3) of Section 5.01(a) and Article 11 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.03 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 Issuer and the Guarantors 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 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 Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in Section 8.03 hereof, clauses (3), (4), (5), (6) and (9) of Section 6.01 hereof shall not constitute Events of Default.

SECTION 8.03. Conditions to Legal Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.02(b) or 8.02(c) hereof to the outstanding Notes:

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, U.S. Legal Tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without reinvestment), in the opinion of a nationally recognized firm of independent public accountants selected by the Issuer, to pay the principal of and interest and premium, if any, on the Notes on the stated date for payment or on the redemption date of the Notes,

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that:

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that, subject to customary assumptions and qualifications, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred,

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating

to other Indebtedness that is concurrently being defeased and, in each case, the granting of Liens in connection therewith),

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a Default under this Indenture or a default under any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound (other than any such Default or default resulting solely from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness that is concurrently being defeased and, in each case, the granting of Liens in connection therewith),

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

SECTION 8.04. Application of Trust Money.

The Trustee or Paying Agent shall hold in trust U.S. Legal Tender and U.S. Government Obligations deposited with it pursuant to this Article Eight, and shall apply the deposited U.S. Legal Tender and the money from U.S. Government Obligations in accordance with this Indenture to the payment of the principal of and the interest on the Notes. The Trustee shall be under no obligation to invest said U.S. Legal Tender and U.S. Government Obligations, except as it may agree with the Issuer.

The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Legal Tender and U.S. Government Obligations deposited pursuant to Section 8.03 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 Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the Issuer’s request any U.S. Legal Tender and U.S. Government Obligations held by it as provided in Section 8.03 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.05. Repayment to the Issuer.

The Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuer cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to such money must look to the Issuer for payment as general creditors unless an applicable law designates another Person.

SECTION 8.06. Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender and U.S. Government Obligations in accordance with this Article Eight by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if the funds deposited

with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of, and interest on, the Notes when due, the Issuer’s obligations under this Indenture, and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender and U.S. Government Obligations in accordance with this Article Eight; provided that if the Issuer has made any payment of interest on, or principal of, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the U.S. Legal Tender and U.S. Government Obligations held by the Trustee or Paying Agent.

SECTION 9.03. [Reserved].

SECTION 9.04. Compliance with the Trust Indenture Act.

From the date on which this Indenture is qualified under the Trust Indenture Act, every amendment, waiver or supplement of this Indenture or the Notes shall comply with the Trust Indenture Act as then in effect.

SECTION 9.05. Revocation and Effect of Consents.

Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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 or subsequent Holder may revoke the consent as to his Note or portion of his Note by notice to the Trustee or the Issuer received before the date on which the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be at least 30 days prior to the first solicitation of such consent. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. The Issuer shall inform the Trustee in writing of the fixed record date if applicable.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (1) through (10) of Section 9.02(b), in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of, and interest on, a Note, on or after the respective due dates therefor, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder.

SECTION 9.06. Notation on or Exchange of Notes.

If an amendment, supplement or waiver changes the terms of a Note, the Issuer may require the Holder of the Note to deliver it to the Trustee. The Issuer shall provide the Trustee with an appropriate notation on the Note about the changed terms and cause the Trustee to return it to the Holder at the Issuer’s expense. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue, and the Trustee shall authenticate, a new Note that reflects the changed terms.

NOTE GUARANTEE

SECTION 11.01. Guarantee.

Subject to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: (a) the principal of and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

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

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

Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee.

SECTION 11.02. [Reserved].

SECTION 11.03. Limitation on Guarantor Liability.

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

intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Guarantor will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Guarantor under this Article Eleven, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. Each Subsidiary Guarantor that makes a payment for distribution under its Note Guarantee is entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the adjusted net assets of each Subsidiary Guarantor.

SECTION 11.04. [Reserved].

SECTION 11.05. Release of a Subsidiary Guarantor; Release of Parent.

(a) A Subsidiary Guarantor shall be released from its obligations under this Indenture and the Registration Rights Agreement:

(1) in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Equity Interests of such Subsidiary Guarantor then held by the Issuer and the Restricted Subsidiaries;

(2) if such Subsidiary Guarantor is designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in each case in accordance with the provisions of this Indenture, upon effectiveness of such designation or when it first ceases to be a Restricted Subsidiary, respectively; or

(3) upon the exercise by the Issuer of its legal defeasance option or covenant defeasance option under Section 8.02 or the discharge of the Issuer’s obligations under this Indenture pursuant to Section 8.01.

The Trustee shall execute an appropriate instrument prepared by the Issuer evidencing the release of a Subsidiary Guarantor from its obligations under this Indenture upon receipt of a request by the Issuer or such Subsidiary Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 11.05; provided, however, that the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers’ Certificates of the Issuer.

Nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Issuer (in which case such Guarantor shall no longer be a Guarantor) or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor.

(b) Notwithstanding any other provisions of this Indenture or the Notes, the Guarantee of the Parent may be released at any time without the consent of any Holder.

8.00% Senior Notes due 2018

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

SECTION 1. Interest. CPI International Acquisition, Inc., a Delaware corporation (the “Issuer”) promises to pay interest on the principal amount of this Note at 8.00% per annum from February 11, 2011 until maturity. The Issuer will pay interest semi-annually on February 15 and August 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”), commencing August 15, 2011. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand to the extent lawful at the interest rate applicable to the Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 2. Method of Payment. The Issuer will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the February 1 or August 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be issued in denominations of $1,000 and integral multiples of $1,000. The Issuer shall pay principal, premium, if any, and interest on the Notes in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts (“U.S. Legal Tender”). Principal, premium, if any, and interest on the Notes will be payable at the office or agency of the Issuer maintained for such purpose except that, at the option of the Issuer, the payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the register of Holders of Notes; provided that for Holders of at least $5.0 million in principal amount of the Notes that have given wire transfer instructions to the Issuer at least ten Business Days prior to the applicable payment date, the Issuer will make all payments of principal, premium and interest by wire transfer of immediately available funds to the accounts specified by the Holders thereof. Notwithstanding the foregoing, all payments with respect to Notes represented by one or more global notes registered in the name of or held by DTC or its nominee will be made by wire transfer of immediately available funds to the account specified by the Holder. Until otherwise designated by the Issuer, the Issuer’s office or agency in New York will be the office of the Trustee maintained for such purpose.

SECTION 3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. Except as provided in the Indenture, the Issuer or any of its Subsidiaries may act in any such capacity.

SECTION 4. Indenture. The Issuer issued the Notes under an Indenture dated as of February 11, 2011 (“Indenture”) by and among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of such terms.

SECTION 5. Optional Redemption. (a) At any time or from time to time on or after February 15, 2015, the Issuer, at its option, may redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below, together with accrued and unpaid interest thereon, if any, to the applicable Redemption Date, if redeemed during the twelve-month period beginning on February 15 of the years indicated:

(c) At any time, and on one or more occasions, prior to February 15, 2014, the Issuer may redeem up to 35% of the aggregate principal amount of Notes with the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal to 108% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to the Redemption Date; provided that (i) at least 65% of the aggregate principal amount of Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption (excluding in such calculation Notes held by Parent and its Subsidiaries) and (ii) such redemption shall occur within 120 days of the date of the closing of any such Qualified Equity Offering. Notice of any redemption upon any Qualified Equity Offering may be given prior to the completion thereof, and any such redemption or notice may, at the Issuer’s discretion, be subject to the closing of the related Qualified Equity Offering.

SECTION 6. [Reserved].

SECTION 7. Notice of Redemption. Notice of redemption will be mailed by first class mail at least 30 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

SECTION 8. Mandatory Redemption. The Issuer shall not be required to make mandatory redemption payments with respect to the Notes, except as described in Section 9.

SECTION 9. Repurchase at Option of Holder. Upon the occurrence of a Change of Control, and subject to certain conditions set forth in the Indenture, the Issuer will be required to offer to purchase all of the outstanding Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase.

The Issuer is, subject to certain conditions and exceptions, obligated to make an offer to purchase Notes at 100% of their principal amount, plus accrued and unpaid interest, if any, thereon to the date of repurchase, with certain net cash proceeds of certain sales or other dispositions of assets in accordance with the Indenture.

The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer and the Registrar are not required to transfer or exchange any Note selected for redemption. Also, the Issuer and the Registrar are not required to transfer or exchange any Notes for a period of 15 days before a selection of Notes to be redeemed.

SECTION 11. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

SECTION 12. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture and the Notes may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or compliance with any provision may be

A-5

waived with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Notes to, among other things, cure any ambiguity, defect or inconsistency in the Indenture, provide for uncertificated Notes in addition to certificated Notes, comply with any requirements of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act, or make any change that does not materially adversely affect the rights of any Holder of a Note.

SECTION 13. Defaults and Remedies. If a Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes generally may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of a Default arising from certain events of bankruptcy or insolvency as set forth in the Indenture, with respect to the Issuer, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal or interest including an accelerated payment or the failure to make a payment on the Change of Control Payment Date or the Net Proceeds Payment Date pursuant to a Net Proceeds Offer or a Default in complying with the provisions of Article Five of the Indenture) 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 and its consequences under the Indenture except a continuing Default in the payment of interest on, or the principal of, or the premium on, the Notes.

SECTION 14. Restrictive Covenants. The Indenture contains certain covenants that, among other things, limit the ability of the Issuer and its Restricted Subsidiaries to make restricted payments, to incur indebtedness, to create liens, to sell assets, to permit restrictions on dividends and other payments by Restricted Subsidiaries of the Issuer, to consolidate, merge or sell all or substantially all of its assets or to engage in transactions with affiliates. The limitations are subject to a number of important qualifications and exceptions. The Issuer must annually report to the Trustee on compliance with such limitations and other provisions in the Indenture.

SECTION 15. No Recourse Against Others. No director, officer, employee, incorporator, stockholder, member or manager of the Issuer or any Guarantor shall have any liability for any obligations of the Issuer under the Notes or the Indenture, or of any Guarantor under its Note Guarantee or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

SECTION 16. Note Guarantees. This Note will be entitled to the benefits of certain Note Guarantees made for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors, the Trustee and the Holders.

SECTION 17. Trustee Dealings with the Issuer. Subject to certain terms, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, their Subsidiaries or their respective Affiliates as if it were not the Trustee.

SECTION 18. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

SECTION 19. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

Pursuant to, but subject to the exceptions in, the Registration Rights Agreement, the Issuer and the Guarantors will be obligated to consummate an exchange offer pursuant to which the Holder of this Note shall have the right to exchange this Note for an 8.00% Senior Note due 2018 of the Issuer which shall have been registered under the Securities Act, in like principal amount and having terms identical in all material respects to this Note (except that such
