(a)                                  General.  The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibits A1 or A2 attached hereto.  The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form reasonably acceptable to the Issuer).  Each Note shall be dated the date of its authentication.  The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.  However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

(b)                                 Global Notes.  Notes issued in global form shall be substantially in the form of Exhibits A1 or A2 attached hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Global Note” or “Schedule of Exchanges of Regulation S Temporary Global Note”, respectively, attached thereto).  Notes issued in definitive form shall be substantially in the form of Exhibit A1 attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Global Note” attached thereto).  Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, repurchases, and redemptions.  Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 and shall be made on the records of the Trustee and the Depositary.

(c)                                  Temporary Global Notes.  Notes offered and sold in reliance on Regulation S shall be issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary, duly executed by the Issuer

34

and authenticated by the Trustee as hereinafter provided.  The Restricted Period shall be terminated upon the receipt by the Trustee of:

(1)                                  a written certificate from the Depositary certifying that it has received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Note (except to the extent of any Beneficial Owners thereof who acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who shall take delivery of a beneficial ownership interest in a 144A Global Note bearing a Private Placement Legend, all as contemplated by Section 2.06(b)); and

(2)                                  an Officer’s Certificate from the Issuer.

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures.  Simultaneously with the authentication of the Regulation S Permanent Global Note, the Trustee shall cancel the Regulation S Temporary Global Note.  The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

SECTION 2.02                                       Execution and Authentication.

At least one Officer must sign the Notes for the Issuer by manual or facsimile signature.

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

A Note shall not be valid until authenticated by the manual signature of the Trustee.  The signature of the Trustee shall be conclusive evidence that the Note has been duly authenticated under this Indenture.

The Trustee shall authenticate and deliver:  (i) on the Issue Date, an aggregate principal amount of $350,000,000 8.00% Senior Secured Notes due 2016, (ii) Additional Notes for an original issue in an aggregate principal amount specified in an Authentication Order pursuant to this Section 2.02 and (iii) Exchange Notes for issue only in an Exchange Offer pursuant to the Registration Rights Agreement, for a like principal amount of Initial Notes or Additional Notes, in each case upon a written order of the Issuer signed by one Officer (an “Authentication Order”).  Such Authentication Order shall specify the amount of the Notes to be authenticated and the date on which the original issue of the Notes is to be authenticated.

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

SECTION 2.03                                       Registrar and Paying Agent.

The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment

35

(“Paying Agent”).  The Registrar shall keep a register of the Notes and of their transfer and exchange.  The Issuer may appoint one or more co-registrars and one or more additional paying agents.  The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent.  The Issuer may change any Paying Agent or Registrar without notice to any Holder.  The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture.  If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such.  The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

The Issuer initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

SECTION 2.04                                       Paying Agent To Hold Money in Trust.

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and shall notify the Trustee of any default by the Issuer in making any such payment.  While any such default continues, the Trustee may require in writing a Paying Agent to pay all money held by it in trust to the Trustee.  The Issuer at any time may require in writing a Paying Agent to pay all money held by it in trust to the Trustee.  Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money.  If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent.  Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.05                                       Holder Lists.

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

Concurrently with the issuance of such Notes, the Trustee shall cause the aggregate principal amount of the applicable Restricted Global Notes to be reduced accordingly, and the Issuer shall execute and the Trustee shall authenticate and deliver to the Persons designated by the Holders of Restricted Definitive Notes so accepted Unrestricted Definitive Notes in the appropriate principal amount.

(A)                              Except as permitted by subparagraph (B) below, each Global Note and each Definitive Note (and all Notes issued in exchange therefor or substitution thereof) shall bear the legend in substantially the following form.

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT OR (C) IT IS AN ACCREDITED INVESTOR (AS DEFINED IN RULE 501(a)(1), (2), (3), OR (7) UNDER THE SECURITIES ACT (AN “ACCREDITED INVESTOR”), (2) AGREES THAT IT WILL NOT WITHIN ONE YEAR AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES (OR HAS FURNISHED ON ITS BEHALF BY A U.S. BROKER-DEALER) TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE FOR THIS SECURITY), (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (F) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE ISSUER SO REQUESTS), OR (G) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN ONE YEAR AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY, IF THE PROPOSED TRANSFEREE IS AN ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

“THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN).  NEITHER THE HOLDER NOR THE BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF PRINCIPAL HEREOF OR INTEREST HEREON.”

46

(h)                                 Cancellation and/or Adjustment of Global Notes.  At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11.  At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(i)                                     General Provisions Relating to Transfers and Exchanges.

(1)                                  To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 or at the Registrar’s request.

(2)                                  No service charge shall be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note 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 (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.06).

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

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

(5)                                  The Issuer shall not be required:

(A)                              to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection;

(B)                                to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(C)                                to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

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

47

(7)                                  The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02.

(8)                                  All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

(9)                                  Neither the Trustee nor the Registrar shall be under any obligation or duty to determine or inquire as to compliance with the Securities Act (including any rules or regulations promulgated thereunder) or any state securities laws that may be applicable in connection with or with respect to any transfer of any interest in any Note (including any transfers between or among Beneficial Owners of interests in any Global Note) or to monitor, determine or inquire as to compliance with any restriction on transfer imposed under this Indenture with respect to transfers of interests in any security (including any transfers between or among Beneficial Owners of interests in any Global Notes); except that the Trustee shall be under a duty to require delivery of such certificates and other documentation, if any, as are expressly required in the applicable circumstance, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance on their face with the express requirements hereof. The Trustee shall have no responsibility for (i) the actions or omissions of the Depositary, or for the accuracy of the books or records of the Depositary and (ii) transfers, of which it has no knowledge, between or among Beneficial Owners of interests in the same Global Note.

SECTION 2.07                                       Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Registrar and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met.  If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced.  The Issuer may charge for its expenses in replacing a Note.

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

SECTION 2.08                                       Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding.  Subject to Section 2.09, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

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

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

48

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 Subsidiaries, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.10                                       Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes (“Temporary Notes”).  Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for Temporary Notes and as may be reasonably acceptable to the Trustee.  Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Notes in exchange for Temporary Notes.

Holders of Temporary Notes shall be entitled to all of the benefits of this Indenture.

SECTION 2.11                                       Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation.  The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment.  The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such canceled Notes (subject to the record retention requirement of the Exchange Act).  Certification of the disposal of all canceled Notes shall be delivered to the Issuer upon its request therefor.  The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.  If the Issuer 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 in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01.  The Issuer shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment.  The Issuer shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest.  At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

SECTION 2.13                                       CUSIP Numbers.

The Issuer in issuing the Notes may use CUSIP numbers and corresponding ISIN numbers (if then generally in use), and, if so, the Trustee will use CUSIP numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and

49

that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption will not be affected by any defect in or omission of such numbers.  The Issuer will promptly notify the Trustee of any change in the CUSIP numbers.

SECTION 2.14                                       Issuance of Additional Notes.

The Issuer will be entitled, from time to time, subject to its compliance with Section 4.09, without consent of the Holders, to issue Additional Notes under this Indenture with identical terms as the Initial Notes issued on the Issue Date other than with respect to (i) the date of issuance, (ii) the issue price, (iii) the amount of interest payable on the first interest payment date and (iv) any adjustments in order to conform to and ensure compliance with the Securities Act (or other applicable securities laws).  The Initial Notes issued on the Issue Date, any Additional Notes and all Exchange Notes issued in exchange therefor will be treated as a single class for all purposes under this Indenture; provided that, if any Additional Notes are not fungible for U.S. federal income tax purposes or securities law purposes with any Notes previously issued, such Additional Notes shall trade separately from such previously issued Notes under a separate CUSIP number but shall otherwise be treated as a single class with all other Notes issued under this Indenture.

With respect to any Additional Notes, the Issuer will set forth in an Officer’s Certificate pursuant to a resolution of the Board of Directors of the Issuer, copies of which will be delivered to the Trustee, the following information:

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

(2)                                  the issue price, the issue date and the CUSIP number of such Additional Notes; and

(3)                                  whether such Additional Notes will be subject to transfer restrictions or will be issued in the form of Exchange Notes.

ARTICLE 3.

REDEMPTION AND PREPAYMENT

SECTION 3.01                                       Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 5 of the Notes, the Issuer shall furnish to the Trustee, at least 30 days but not more than 60 days before the redemption date, an Officer’s Certificate setting forth:

(1)                                  the clause of this Indenture pursuant to which the redemption shall occur;

(2)                                  the redemption date;

(3)                                  the principal amount of the Notes to be redeemed; and

(4)                                  the redemption price.

50

SECTION 3.02                                       Selection of Notes To Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select Notes for redemption or purchase on a pro rata basis except:

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

(2)                                  if otherwise required by law.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased.  Notes and portions of Notes selected shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased.  Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

SECTION 3.03                                       Notice of Redemption.

Subject to the provisions of Section 3.09, at least 30 days but not more than 60 days before a redemption date, the Issuer shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 of this Indenture.

The notice shall identify the Notes to be redeemed (including CUSIP Number(s)) and shall state:

(1)                                  the redemption date;

(2)                                  the redemption price;

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

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

(5)                                  that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

51

(6)                                  that, unless the Issuer defaults in making such redemption payment, interest and Additional Interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

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

(8)                                  that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least 45 days prior to the redemption date (or such shorter period as to which the Trustee may agree), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

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 irrevocably due and payable on the redemption date at the redemption price.  A notice of redemption may be conditional.

SECTION 3.05                                       Deposit of Redemption or Purchase Price.

On the relevant redemption or purchase date, the Issuer shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed or purchased on that date.  The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or purchased.

If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest and Additional Interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase.  If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date.  If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

SECTION 3.06                                       Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Issuer shall issue and, upon receipt of an Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered; provided that each new Note will be in denominations of $2,000 or an integral multiple of $1,000 in excess thereof.

52

SECTION 3.07                                       Optional Redemption.

The Notes are subject to optional redemption as provided in Section 5 of each of the Notes.  Any redemption of the Notes pursuant to such Section shall be made pursuant to the provisions of Sections 3.01 through 3.06.

SECTION 3.08                                       Mandatory Redemption

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

SECTION 3.09                                       Offer To Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10, the Issuer is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it shall follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders and if the Issuer elects (or is required by the terms of other pari passu indebtedness), all holders of other Indebtedness that is pari passu with the Notes.  The Asset Sale Offer shall remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”).  No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuer shall apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness, if any, (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer.  Payment for any Notes so purchased shall be made pursuant to Section 4.01.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest and Additional Interest, if any, 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 Asset Sale Offer.

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

(1)                                  that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 and the length of time the Asset Sale Offer shall remain open;

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

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

(4)                                  that, unless the Issuer defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest after the Purchase Date;

(5)                                  that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in a minimum amount of $2,000 or an integral multiple of $1,000 in excess thereof only;

53

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

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

(8)                                  that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Issuer shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, shall be purchased); and

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

The Issuer shall pay or cause to be paid the principal of, premium, if any, and interest and Additional Interest, if any, on the Notes on the dates and in the manner provided in the Notes.  Principal, premium, if any, and interest and Additional Interest, if any, shall be considered paid on the date due if the Paying Agent, if other than the Issuer or a Subsidiary thereof, holds on the due date money deposited by or on behalf of the Issuer in immediately available funds and designated for and sufficient to pay all

54

principal, premium, if any, and interest then due.  The Issuer shall pay all Additional Interest, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement.

The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest (without regard to any applicable grace period) at the same rate to the extent lawful.  Interest on the Notes shall accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid.  Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

SECTION 4.02                                       Maintenance of Office or Agency.

The Issuer shall maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served.  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 fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

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 an office or agency in the Borough of Manhattan, the City of New York for such purposes.  The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 4.03                                       Reports.

(a)                                  Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Issuer shall furnish to the Trustee and to Cede & Co., the nominee of DTC, and the Holders of the Notes, within the time periods that are applicable to the Issuer (or, if not applicable, would be if the Issuer were required to file such reports under 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 was required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that describes the Issuer’s consolidated financial condition and results of operation and, with respect to the annual information only, a report thereon by the Issuer’s independent registered public accountants but not any assessment, attestation or audit of internal controls pursuant to Section 404 of the Sarbanes-Oxley Act or rules and regulations promulgated thereunder; and

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

(b)                                 The Issuer may satisfy its obligation to furnish such information to the Trustee and Cede & Co. at any time by filing such information with the SEC.  If, notwithstanding the foregoing, the SEC

55

will not accept such filings for any reason, the Issuer will post the reports specified in the preceding sentence on its website within the time periods that would apply if the Issuer were required to file those reports with the SEC.  In addition, the Issuer agrees that, for so long as any Notes remain outstanding, the Issuer will furnish to any Beneficial Owner of Notes or to any prospective purchaser of Notes in connection with any sale thereof, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(c)                                  If at any time Holdings (or any other direct or indirect parent company of the Issuer) becomes a Guarantor of the Notes (there being no obligation of Holdings or any other direct or indirect parent company of the Issuer to do so), and Holdings (or such other parent company) holds no material assets other than cash, Cash Equivalents and the Capital Stock of the Issuer, Holdings or any other direct or indirect parent company of the Issuer (and performs the related incidental activities associated with such ownership) and complies with the requirements of Rule 3-10 of Regulation S-X promulgated by the SEC (or any successor provision), the reports, information and other documents required to be furnished to the Trustee and Cede & Co. or filed with the SEC pursuant to this Section 4.03 may, at the option of the Issuer, be those of Holdings (or such other parent company) rather than the Issuer.

(d)                                 Notwithstanding anything herein to the contrary, the Issuer will not be deemed to have failed to comply with any of its obligations hereunder for purposes of Section 6.01(4) until 90 days after the date any report hereunder is due.

(e)                                  Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

SECTION 4.04                                       Compliance Certificate.

(a)                                  The Issuer shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Issuer, an Officer’s Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether the Issuer has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to such Officer signing such certificate, that to his or her knowledge the Issuer has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto).

(b)                                 So long as any of the Notes are outstanding, the Issuer shall deliver to the Trustee, within 30 days upon any Officer becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto.

SECTION 4.05                                       [Reserved].

SECTION 4.06                                       Stay, Extension and Usury Laws.

The Issuer and each of the Guarantors covenant (to the extent that they may lawfully do so) that they shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or

56

advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

(D)                               make any Restricted Investment;

(20)                            any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the Indebtedness, preferred stock, Liens, agreements, contracts, licenses, leases, subleases, instruments or obligations referred to in clauses (1), (2), (4) through (15) and (17) above; provided, however, that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, (as determined by the Issuer in good faith) than those restrictions contained in the Indebtedness, preferred stock, Liens, agreements, contracts, licenses, leases, subleases, instruments or obligations referred to in clauses (1), (2), (4) through (15) and (17) above, as applicable prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

For purposes of determining compliance with this covenant, (i) the priority of any preferred stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability to make distributions on Capital Stock and (ii) the subordination of loans or advances made to the Issuer or a Restricted Subsidiary of the Issuer to other Indebtedness incurred by the Issuer or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances.

(a)                                  The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Issuer shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Issuer and its Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or preferred stock, if the Fixed Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such preferred stock is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period; provided that the maximum amount of Indebtedness that may be incurred by Non-Guarantor Subsidiaries under this clause (a) shall be $15.0 million outstanding at any time.

(5)                                  the incurrence by the Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness or Replacement Preferred Stock in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) or any Disqualified Stock or preferred stock that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (2), (3), (5), (18) or (19) of this Section 4.09(b);

(6)                                  the incurrence by the Issuer, any Guarantors or any Restricted Subsidiaries of intercompany Indebtedness between or among the Issuer, Guarantors and any Restricted Subsidiaries; provided, however, that:

(B)                                (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Issuer or a Qualified Restricted Subsidiary of the Issuer and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Issuer or a Qualified Restricted Subsidiary of the Issuer, shall be deemed, in each case, to constitute a new incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be, which new incurrence is not permitted by this clause (6);

(7)                                  the issuance by any Restricted Subsidiaries to the Issuer, Guarantors or to any of their Restricted Subsidiaries of shares of preferred stock; provided, however, that:

(A)                              any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Issuer, or Guarantor or a Restricted Subsidiary of the Issuer; and

65

(B)                                any sale or other transfer of any such preferred stock to a Person that is not either the Issuer, a Guarantor or a Restricted Subsidiary of the Issuer,

will be deemed, in each case, to constitute a new issuance of such preferred stock by such Restricted Subsidiary which new issuance is not permitted by this clause (7);

(8)                                  the incurrence by the Issuer or any of its Restricted Subsidiaries of Hedging Obligations for the purpose of limiting interest rate, currency or commodity risk;

(A)                              by the Issuer or any of the Guarantors of Indebtedness of the Issuer or a Restricted Subsidiary of the Issuer that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to the Notes, then the Guarantee shall be subordinated to the same extent as the Indebtedness guaranteed; and

(B)                                by any Non-Guarantor Subsidiary of Indebtedness of a Non-Guarantor Subsidiary;

(10)                            the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, letters of credit, performance bonds, surety bonds, appeal bonds or other similar bonds in the ordinary course of business;

(11)                            the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business, so long as such Indebtedness is extinguished within five Business Days;

(12)                            the incurrence of Indebtedness arising from agreements of the Issuer or a Restricted Subsidiary providing for indemnification, adjustment of purchase price, holdback, contingency payment obligations or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or Capital Stock of the Issuer or any Restricted Subsidiary;

(14)                            the incurrence of Indebtedness resulting from endorsements of negotiable instruments for collection in the ordinary course of business;

(21)                            Indebtedness representing deferred compensation to employees of the Issuer and the Restricted Subsidiaries incurred in the ordinary course of business.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (21) above, or is entitled to be incurred pursuant to Section 4.09(a), the Issuer shall be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09 except that Indebtedness under the Credit Agreement outstanding on the Issue Date will be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of this Section 4.09(b).  The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock or preferred stock in the form of additional shares of the same class of Disqualified Stock or preferred stock shall not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock for purposes of this Section 4.09.

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

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

(2)                                  the principal amount of the Indebtedness, in the case of any other Indebtedness; and

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

(A)                              the Fair Market Value of such assets at the date of determination; and

67

(B)                                the amount of the Indebtedness of the other Person.

SECTION 4.10                                       Asset Sales.

(a)                                  The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1)                                  the Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of;

(2)                                  if such Asset Sale involves the disposition of Collateral, the Issuer or such Restricted Subsidiary has complied with the provisions of this Indenture and the Security Documents; and

(3)                                  at least 75% of the consideration received in the Asset Sale by the Issuer or such Restricted Subsidiary is in the form of cash.  For purposes of this paragraph (3), each of the following shall be deemed to be cash:

(A)                              Cash Equivalents;

(B)                                any liabilities (as shown on the Issuer’s most recent consolidated balance sheet) of the Issuer or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to an agreement that releases the Issuer or such Restricted Subsidiary from further liability;

(C)                                any securities, notes or other obligations received by the Issuer or any such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash within 180 days of receipt, to the extent of the cash received in that conversion;

(D)                               (i) any Designated Noncash Consideration received by the Issuer or a Restricted Subsidiary in connection with the sale or contribution of assets by the Issuer or a Restricted Subsidiary to a joint venture with a Strategic Investor; provided, however, that (x) any such Designated Noncash Consideration that is converted into Cash Equivalents shall be treated as Net Proceeds in the manner set forth in Section 4.10(b) and (y) in the event such Designated Noncash Consideration is an Investment (other than in the form of Indebtedness), such Designated Noncash Consideration shall be deemed to have been acquired and consequently reduce amounts available under clause (15) or (17) of the definition of “Permitted Investments,” as determined by the Issuer and (ii) any Designated Noncash Consideration the Fair Market Value of which, when taken together with all other Designated Noncash Consideration received pursuant to this clause (ii) (and not subsequently converted into Cash Equivalents that are treated as Net Proceeds of an Asset Sale), does not exceed the greater of $20.0 million and 2.5% of Total Assets at the time of receipt since the Issue Date, with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value; and

(E)                                 any stock or assets of the kind referred to in clause (2) or (4) of Section 4.10(b).

68

Notwithstanding the foregoing, the 75% requirement referred to in clause (3) above shall not apply to any Asset Sale in which the cash or Cash Equivalent portion of the consideration received therefrom, determined in accordance with the foregoing provision, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% requirement.

(b)                                 Within 450 days after the receipt of any Net Proceeds from an Asset Sale, the Issuer (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds at its option:

(1)                                  to repay or prepay (x) any Priority Payment Lien Obligations and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto or (y) Pari Passu Lien Indebtedness (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto) or redeem Notes as provided under “Optional Redemption” or by making an Asset Sale Offer (in accordance with the procedures set forth in Section 4.10(c)); provided that in the case of a reduction of Obligations other than under the Notes under this clause (y) the Issuer shall use commercially reasonable efforts to equally and ratably redeem Notes as provided under Section 3.07 or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders of Notes to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid;

(2)                                  to (x) acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Guarantor or a Qualified Restricted Subsidiary of the Issuer or (y) make Investments pursuant to clause (15) or (17) of the definition of “Permitted Investments”;

(3)                                  to make a capital expenditure with respect to a Permitted Business; or

(4)                                  to acquire Additional Assets;

provided that the requirements of clauses (2) through (4) of this Section 4.10(b) shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to in any of clauses (2) through (4) of this Section 4.10(b) is entered into by the Issuer or its Restricted Subsidiary within 450 days after the receipt of such Net Proceeds with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment in accordance with such agreement within 180 days of such commitment and if such Net Proceeds are not so applied within such 180-day period, then such Net Proceeds shall constitute Excess Proceeds (as defined in Section 4.10(c)).  In addition, to the extent that the assets that were the subject of the Asset Sale constituted Collateral, the assets acquired with the proceeds pursuant to any of clauses (2) through (4) above or acquired as consideration for such Asset Sale shall constitute Collateral.

Pending the final application of any Net Proceeds, the Issuer may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture.

(c)                                  Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, within ten Business Days thereof, the Issuer shall make an Asset Sale Offer to, (i) in the case of Net Proceeds from Collateral, all holders of First Lien Obligations containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets; and (ii) in the case of any other Net Proceeds, all holders of other Indebtedness that ranks pari

69

passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (“Pari Passu Debt”).

The offer price in any Asset Sale Offer shall be equal to 100% of the principal amount plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase, and shall be payable in cash.  If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture.  If the aggregate principal amount of First Lien Obligations (in the case of Net Proceeds from Collateral) or First Lien Obligations and Pari Passu Debt (in the case of any other Net Proceeds) tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased, and the representative(s) for the holders of other First Lien Obligations shall select such other First Lien Obligations (and, if applicable, Pari Passu Debt) to be purchased and prepaid, on a pro rata basis.  Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d)                                 The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer.  To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 or this Section 4.10, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Section 3.09 or this Section 4.10 by virtue of such compliance.

SECTION 4.11                                       Transactions with Affiliates.

(a)                                  The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Issuer involving aggregate consideration in excess of $5.0 million (each, an “Affiliate Transaction”), unless:

(1)                                  the Affiliate Transaction is on terms that, taken as a whole, are not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person; and

(2)                                  the Issuer delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the members of the Board of Directors of the Issuer, together with a certified copy of the resolutions of the Board of Directors of the Issuer approving such Affiliate Transaction or Affiliate Transactions.

(b)                                 The following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of Section 4.11(a):

(1)                                  any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Issuer or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto;

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

70

(5)                                  any issuance of Equity Interests (other than Disqualified Stock) of the Issuer to Affiliates of the Issuer;

(9)                                  loans (or cancellation of loans) or advances to employees in the ordinary course of business;

(10)                            transactions with joint ventures, Unrestricted Subsidiaries, customers, suppliers, contractors, joint venture partners (including without limitation, physicians) or purchasers or sellers of goods or services, in each case which are in the ordinary course of business (including, without limitation, pursuant to joint venture agreements) and otherwise in compliance with the terms of this Indenture;

(11)                            the existence of, or the performance by the Issuer or any Restricted Subsidiary of their obligations, if any, or obligations of Holdings under the terms of, any subscription, registration rights or stockholders agreement, partnership agreement, limited liability company agreement or similar agreement to which Holdings, the Issuer or any Restricted Subsidiary is a party as of the Issue Date and any similar agreements which the Issuer, any Restricted Subsidiary, Holdings or any other direct or indirect parent company of the Issuer may enter into thereafter; provided, however, that the entering into by the Issuer or any Restricted Subsidiary or the performance by the Issuer or any Restricted Subsidiary of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date will only be permitted by this clause (11) to the extent that the terms of any such amendment or new agreement, taken as a whole, are not materially disadvantageous to the holders of the Notes, as determined in good faith by the Board of Directors, chief executive officer or chief financial officer of the Issuer;

(12)                            the Transactions, including all payments made or to be made in connection with the Transactions as described in the Offering Memorandum;

The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind, on or with respect to the Collateral except Permitted Collateral Liens.  The Issuer will not, and will not permit any of the Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien (other than Permitted Liens) of any kind securing Indebtedness upon any of their property or assets (other than with respect to property or assets constituting Collateral), now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien.

SECTION 4.15                                       Offer To Repurchase Upon Change of Control.

(a)                                  If a Change of Control occurs, each Holder shall have the right to require the Issuer to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased to the date of purchase subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”).  Within 30 days following any Change of Control, the Issuer shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:
