THE NOTES

SECTION 2.01           Form and Dating.

(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 Interests in the Global Note” 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 Interests in the 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, at its New York office, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary, duly executed by the Issuer 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 or Concentra.

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 $650.0 million 6.875% Senior Notes due 2032 and (ii) Additional Notes for an original issue in an aggregate principal amount specified in an Authentication Order pursuant to this Section 2.02, 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 (“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, 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. 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.

SECTION 2.06          Transfer and Exchange.

(a)            Transfer and Exchange of Global Notes. A Global Note may not be transferred except in whole (but not in part) by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes shall be exchanged by the Issuer for Definitive Notes if:

(1)          the Depository (a) notifies the Issuer that it is unwilling or unable to continue as Depositary for the Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days after the date of such notice from the Depositary;

(2)          there has occurred and is continuing a Default or an Event of Default with respect to the Notes.

Upon the occurrence of any of the preceding events in (1) or (2) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c).

(b)           Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also shall require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).

(2)           All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(1) above, the transferor of such beneficial interest must deliver to the Registrar either:

(3)           Transfer of Beneficial Interests to Another Restricted Global Note.

(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.

(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.

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 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 and any Additional Notes will be treated as a single class for all purposes 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 Concentra, 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; provided, however, that no Additional Notes may be issued at a price that would cause such Additional Notes to have “original issue discount” within the meaning of Section 1273 of the Internal Revenue Code of 1986, as amended; and

(3)           whether such Additional Notes will be subject to transfer restrictions.

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 10 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 Notes to be redeemed; and

(4)           the redemption price.

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 10 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 and 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 10 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 11 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;

(6)           that, unless the Issuer defaults in making such redemption payment and interest 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 a 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, except as otherwise set forth in this Section 3.04. Notice of any redemption of the Notes in connection with a transaction or an event (including an Equity Offering, an incurrence of Indebtedness or a Change of Control) may, at the Issuer’s discretion, be given prior to the completion or the occurrence thereof and any such redemption or notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of the related transaction or event. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was delivered) as any or all conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. In addition, the Issuer may provide in such notice that payment of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

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 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 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 shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase unless the applicable notice of redemption is conditional in accordance with Section 3.04 and the relevant conditions are not satisfied or waived. 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.

SECTION 3.07           Optional Redemption.

The Notes are subject to optional redemption as provided in Section 5 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

Except as set forth with respect to the Special Mandatory Redemption, other than with respect to any such obligations that may arise as set forth under Sections 4.10 or 4.15, 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 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 the denomination of $2,000 and integral multiples of $1,000 in excess thereof only;

(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).

On or before the Purchase Date, the Issuer shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and shall deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase, and the Issuer shall promptly issue a new Note, and the Trustee, upon written request from the Issuer, shall authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Asset Sale Offer on the Purchase Date.

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

SECTION 3.10            Escrow of Proceeds; Special Mandatory Redemption.

(a)            The initial funds deposited in the Escrow Account, and all other funds, securities, interest, dividends, distributions, earnings and other property and payments credited to the Escrow Account in connection with the notes are referred to, collectively, as the “Escrowed Funds.” In the Escrow Agreement, the Escrow Issuer will grant the Trustee, for the benefit of the Trustee and the Holders of the Notes, a security interest in the Escrow Account and the Escrowed Funds to secure the Special Mandatory Redemption (as defined below); provided, however, that such Lien and security interest shall be automatically extinguished on and terminate at the time of the Escrow Release (as defined below).

(b)            Pursuant to the Escrow Agreement, the Escrow Agent will release the Escrowed Funds (the “Escrow Release”) to, or at the order of, the Escrow Issuer (the date of such release being referred to as the “Escrow Release Date”) upon receipt by each of the Escrow Agent and the Trustee of an Officer’s Certificate from the Escrow Issuer or Concentra addressed to the Escrow Agent and the Trustee on or prior to September 30, 2024 (the “Outside Date”), certifying that the Escrow Release Conditions (as defined in the Escrow Agreement) will be met promptly following the Escrow Release on the Escrow Release Date. Upon the occurrence of the Escrow Release, the Escrow Account shall be reduced to zero and the Escrowed Funds and interest accrued thereon from the date of deposit shall be paid out in accordance with the terms of the Escrow Agreement.

(c)            In the event that (i) the Escrow Agent shall not have received the Officer’s Certificate described above on or prior to the Outside Date or (ii) Concentra shall notify the Escrow Agent in writing that Concentra has determined that the Separation will not be consummated on or prior to the Outside Date or otherwise announces that the Separation and the Initial Public Offering have been or will be abandoned (each such event being a “Special Mandatory Redemption Event”), the Escrow Issuer will redeem the notes (the “Special Mandatory Redemption”) at a price equal to 100% of the initial issue price of the Notes, plus accrued and unpaid interest from the Issue Date, or from the most recent date to which interest has been paid, to, but not including the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”). Within three Business Days following the occurrence of a Special Mandatory Redemption Event, the Escrow Issuer shall deliver a notice to the Trustee and the Escrow Agent of the occurrence thereof (a “Special Redemption Notice”). Within five Business Days after the Special Mandatory Redemption Event or as otherwise required by DTC’s procedures, the Escrow Issuer will redeem the notes at the Special Mandatory Redemption Price pursuant to the procedures described in Section 3.10(d) (the date of such redemption, the “Special Mandatory Redemption Date”).

(d)            If the Escrow Agent receives a Special Redemption Notice, the Escrow Agent will liquidate all Escrowed Funds then held by it not later than the last Business Day prior to the Special Mandatory Redemption Date. On the Business Day prior to the Special Mandatory Redemption Date, the Escrow Agent shall pay to the Trustee for payment to each Holder the Special Mandatory Redemption Price for such Holder’s notes. Any redemption made pursuant to this Section 3.10 shall be made pursuant to the procedures set forth in this Indenture and the Escrow Agreement, except to the extent inconsistent with this Section 3.10, which shall control in the event of a conflict.

COVENANTS

SECTION 4.01           Payment of Notes.

The Issuer shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than Concentra 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 principal, premium, if any, and interest then due.

The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at 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 (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.

The Issuer hereby designates the New York Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.03.

SECTION 4.03           Reports.

(a)            Whether or not required by the rules and regulations of the SEC, from and after the Escrow Release Date, so long as any Notes are outstanding, Concentra shall furnish to the Trustee and the Holders:

(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 Concentra were a non-accelerated filer that was required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that describes Concentra’s consolidated financial condition and results of operation and, with respect to the annual information only, a report thereon by Concentra’s independent registered public accountants,

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

(3)            simultaneously with the delivery of each set of consolidated annual and quarterly financial information referred to in clause (1) above, reasonably detailed unaudited financial information showing separately the financial position and results of Concentra and its Restricted Subsidiaries, on the one hand, and the Unrestricted Subsidiaries, on the other hand, as of and for the applicable periods covered by such financial information; provided that (x) in the case of the information required by this clause (3) to accompany delivery of each set of annual financial information referred to in clause (1) above, (A) condensed consolidating balance sheets shall only be required to be provided as of the end of the relevant fiscal year, (B) condensed consolidating statements of operations shall only be required to be provided for the relevant fiscal year, and not for any prior periods, and (C) no condensed consolidating statements of cash flows shall be required, and (y) in the case of the information required by this clause (3) to accompany delivery of each set of quarterly financial information referred to in clause (1) above, (A) condensed consolidating balance sheets shall only be required to be provided as of the end of the relevant fiscal quarter, (B) condensed consolidating statements of operations shall only be required to be provided for the relevant fiscal quarter and the then-elapsed portion of the current fiscal year, and not for any prior periods, and (C) no condensed consolidating statements of cash flows shall be required; provided, further, that in no event shall Concentra be required by this clause (3) to provide any financial information with respect to the Unrestricted Subsidiaries that would not otherwise be required with respect to non-guarantor subsidiaries by Rule 13-10 of Regulation S-X promulgated by the SEC (or any successor provision), as amended and then in effect, if Concentra had guaranteed debt securities registered with the SEC.

(b)           Notwithstanding anything to the contrary in clause (a) above, no reports required thereby will be required to contain the separate financial information for Guarantors contemplated by Rule 13-10 of Regulation S-X promulgated by the SEC. Concentra may satisfy its obligation to furnish such information to the Trustee, Cede & Co. and the Holders at any time by filing such information with the SEC. In addition, for so long as any Notes remain outstanding, Concentra shall 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 any direct or indirect parent holding company of Concentra becomes a Guarantor of the Notes (there being no obligation of any direct or indirect parent holding company of Concentra to do so), and such parent holding company complies with the requirements outlined above, the reports, information and other documents required to be furnished to the Trustee, Cede & Co. and the Holders or filed with the SEC pursuant to this Section 4.03 may, at the option of Concentra, be those of such parent holding company rather than Concentra.

(d)           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 Concentra, an Officer’s Certificate stating that a review of the activities of Concentra and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuer has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each 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.

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 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.

SECTION 4.07           Restricted Payments.

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

(A)            declare or pay any dividend or make any other payment or distribution on account of Concentra’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving Concentra or any of its Restricted Subsidiaries) or to the direct or indirect holders of Concentra’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of Concentra); provided that the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of a Restricted Subsidiary of Concentra shall not constitute a Restricted Payment;

(a)            Concentra 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 Concentra 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 the Guarantors may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or preferred stock, if the Fixed Charge Coverage Ratio of Concentra for Concentra’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.

(b)            Section 4.09(a) shall not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, “Permitted Debt”):

(2)            the incurrence by Concentra and its Restricted Subsidiaries of the Existing Indebtedness;

(4)            the incurrence or issuance by Concentra or any of its Restricted Subsidiaries of Indebtedness (including Capital Lease Obligations), Disqualified Stock or preferred stock, in each case, incurred or issued for the purpose of financing all or any part of the purchase price or cost of design, construction, lease, installation or improvement of any fixed or capital assets and any Indebtedness assumed by Concentra or any of its Restricted Subsidiaries in connection with the acquisition of any such assets or secured by a Lien on any such assets prior to the acquisition thereof, in an aggregate principal amount, including all Permitted Refinancing Indebtedness (except as permitted by the definition of “Permitted Refinancing Indebtedness”) and Replacement Preferred Stock (except as permitted by the definition of “Replacement Preferred Stock”) incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of $87.5 million and 25% of LTM Adjusted EBITDA at such time;

(5)            the incurrence by Concentra 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), (4), (5), (13), (15), (17) or (18) of this Section 4.09(b);

(6)            the incurrence by Concentra or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Concentra and any of its 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 Concentra or a Restricted Subsidiary of Concentra and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either Concentra or a Restricted Subsidiary of Concentra, shall be deemed, in each case, to constitute a new incurrence of such Indebtedness by Concentra or such Restricted Subsidiary, as the case may be, which new incurrence is not permitted by this clause (6);

(7)            the issuance by any of Concentra’s Restricted Subsidiaries to Concentra or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that:

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

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 Concentra or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business;

(10)            the incurrence by Concentra 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; provided, however, that upon the drawing of letters of credit for reimbursement obligations, including with respect to workers’ compensation claims, or the incurrence of other Indebtedness with respect to reimbursement type obligations regarding workers’ compensation claims, such obligations are reimbursed within 30 days following such drawing or incurrence;

(11)            the incurrence by Concentra 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 Concentra 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 Concentra or any Restricted Subsidiary;

(13)            the incurrence of Indebtedness or the issuance of any Disqualified Stock or preferred stock by any Non-Guarantor Subsidiary and any Foreign Subsidiary of Concentra, collectively, in an amount not to exceed $87.5 million at any time outstanding;

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

(A)            the Issuer would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) or

(B)            Concentra’s Fixed Charge Coverage Ratio after giving pro forma effect to such acquisition, merger or consolidation would be greater than Concentra’s actual Fixed Charge Coverage Ratio immediately prior to such acquisition, merger or consolidation;

(18)            the incurrence or issuance by Concentra or any of its Restricted Subsidiaries of additional Indebtedness, Disqualified Stock or preferred stock in an aggregate principal amount (or accreted value or liquidation preference, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness (except as permitted by the definition of “Permitted Refinancing Indebtedness”) and all Replacement Preferred Stock (except as permitted by the definition of “Replacement Preferred Stock”) incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness, Disqualified Stock and preferred stock incurred or issued pursuant to this clause (18), not to exceed the greater of $300.0 million and 75% of LTM Adjusted EBITDA at such time;

(19)            the incurrence by Concentra or any of its Restricted Subsidiaries of Indebtedness in the form of loans from a Captive Insurance Subsidiary;

(22)            Indebtedness owing to Select or its subsidiaries incurred in connection with the Transactions.

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (or any portion thereof) at any time, whether at the time of incurrence or upon the application of all or a portion of the proceeds thereof or subsequently 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 incurred or outstanding on the Escrow Release Date will be deemed to have been incurred 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; provided in each such case, that the amount thereof is included in Fixed Charges of Concentra as accrued (other than the reclassification of preferred stock as Indebtedness due to a change in accounting principles).

For purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness, the dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to extend, replace, refund, refinance, renew or defease other Indebtedness denominated in a foreign currency, and such extension, replacement, refunding, refinancing, renewal or defeasance would cause the applicable dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such extension, replacement, refunding, refinancing, renewal or defeasance, such dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased, plus the aggregate amount of fees, underwriting discounts, premiums (including tender premiums) and other costs and expenses (including original issue discount) incurred in connection with such refinancing.

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

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

SECTION 4.10              Asset Sales.

(a)            Concentra 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; and

(2)            at least 75% of the consideration received in the Asset Sale by Concentra or such Restricted Subsidiary is in the form of cash. For purposes of this paragraph (2), each of the following shall be deemed to be cash:

(A)            Cash Equivalents;

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

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

(D)            any Designated Noncash Consideration the Fair Market Value of which, when taken together with all other Designated Noncash Consideration received pursuant to this clause (d) (and not subsequently converted into Cash Equivalents that are treated as Net Proceeds of an Asset Sale), does not exceed $50.0 million since the Escrow Release 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 clauses (2) or (4) of Section 4.10(b).

Notwithstanding the foregoing, the 75% limitation referred to in clause (2) above shall not apply to any Asset Sale in which the cash or Cash Equivalents 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% limitation.

(b)            Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Concentra (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds at its option:

(1)            to repay Indebtedness outstanding pursuant to Section 4.09(b)(1) and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2)            to 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 Restricted Subsidiary of Concentra;

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

(4)            to acquire Additional Assets; or

(5)            to repay (i) Notes or (ii) any other Indebtedness (other than Indebtedness owing to Concentra or a Restricted Subsidiary) that is pari passu in right of payment with the Notes, and in the case of revolving Indebtedness, to correspondingly reduce commitments with respect thereto; provided that if Concentra or any of its Restricted Subsidiaries shall so repay any Indebtedness other than the Notes, the Issuer will repay the Notes on a pro rata basis by, at its option, (A) redeeming Notes pursuant to Section 3.07 or (B) purchasing Notes through open-market purchases, at a price equal to or higher than 100% of the principal amount thereof, or making an offer (in accordance with the procedures set forth below) to all Holders to purchase their Notes on a ratable basis with such other Indebtedness for no less than 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, thereon up to the principal amount of Notes to be repurchased;

provided that the requirements of clauses (2) through (4) above 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) above is entered into by Concentra or its Restricted Subsidiary within 365 days after the receipt of such Net Proceeds and such Net Proceeds are applied in accordance with such agreement.

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 $60.0 million, within ten Business Days thereof, the Issuer shall make an Asset Sale Offer to all Holders and if the Issuer elects (or is required by the terms of such other pari passu Indebtedness), any holders of other Indebtedness that is pari passu in right of payment with the Notes. The offer price in any Asset Sale Offer shall be equal to 100% of the principal amount plus accrued and unpaid 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 Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Notes and such other pari passu Indebtedness shall be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall 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)            Concentra 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 Concentra involving aggregate consideration in excess of $5.0 million for any individual transaction or series of related transactions (each, an “Affiliate Transaction”), unless:

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

(2)            with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, the Issuer delivers to the Trustee an Officer’s Certificate certifying that such Affiliate Transaction complies with this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of Concentra, together with a certified copy of the resolutions of the Board of Directors of Concentra 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, change of control agreement, severance agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by Concentra or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto;

(2)            transactions between or among Concentra, its Restricted Subsidiaries and/or any entity that becomes a Restricted Subsidiary as a result of such transaction;

Concentra shall not, and shall not permit any of its Restricted Subsidiaries to create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, 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.

(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, 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:

(1)            that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered shall be accepted for payment;

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

(7)            that Holders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof; and

(8)            that Holders electing to have a Note purchased pursuant to a Change of Control Offer may elect to have Notes purchased in denominations of $2,000 and integral multiples of $1,000 in excess thereof only.

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 those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Sections 3.09 or 4.15 of this Indenture, 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 4.15 by virtue of such compliance.

(b)            On the Change of Control Payment Date, the Issuer shall, to the extent lawful:

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

(2)            deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

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

The Paying Agent shall promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c)            Notwithstanding anything to the contrary in this Section 4.15, the Issuer shall not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes validly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given in respect of all Notes pursuant to Section 3.07 of this Indenture, unless and until there is a Default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of, and conditioned upon the occurrence of, a 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.

(d)            Notwithstanding anything to the contrary in this Section 4.15, in no event will the consummation of the Escrow Merger, the Transactions or the Distribution constitute a Change of Control.

SECTION 4.16             Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of Concentra may designate any Restricted Subsidiary (other than the Issuer or a direct or indirect parent company of the Issuer) to be an Unrestricted Subsidiary if no Default would be in existence following such designation. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Concentra and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of the designation and shall reduce the amount available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of Permitted Investments, as determined by the Issuer. That designation shall only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

The Board of Directors of Concentra may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of Concentra; provided that such designation shall be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Concentra of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation shall only be permitted if such Indebtedness is permitted under Section 4.09 and no Default or Event of Default would be in existence following such designation.

SECTION 4.17             [Reserved].

SECTION 4.18             Additional Note Guarantees.

If Concentra or any of its Restricted Subsidiaries acquires or creates another Subsidiary, other than a Non-Guarantor Subsidiary or if any Non-Guarantor Subsidiary otherwise ceases to be a Non-Guarantor Subsidiary, in each case, after the Escrow Release Date then such Subsidiary shall become a Guarantor and execute a supplemental indenture substantially in the form attached hereto as Exhibit E2 and deliver an Opinion of Counsel to the Trustee within 30 Business Days of the date on which it was acquired or created or ceased to be a Non-Guarantor Subsidiary, as applicable.

SECTION 4.19             Activities Prior to Escrow Release.

Prior to the Escrow Merger, the Escrow Issuer will be a wholly owned subsidiary of CHSI and its primary activities will be restricted to issuing the Notes, performing its obligations in respect of the Notes under this Indenture and the Escrow Agreement, instructing the Escrow Agent with respect to the investment of the Escrowed Funds in specified cash and Cash Equivalents in accordance with the terms of the Escrow Agreement, consummating the Assumption, redeeming the Notes pursuant to Section 3.10 on the Special Mandatory Redemption Date, if applicable, and conducting such other activities as are necessary or appropriate to carry out the activities described above. The Escrow Issuer will not own, hold or otherwise have any interest in any assets other than the Escrowed Funds and the Escrow Account. Prior to the Assumption, the Escrow Issuer will not engage in any business operations or other activities other than those contemplated in this Section 4.19.

(A)            is caused by a failure to pay principal at the final Stated Maturity of such Indebtedness (a “Payment Default”); or

(B)            results in the acceleration of such Indebtedness prior to its express maturity;

and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $75.0 million or more;

(6)            with respect to any judgment or decree for the payment of money (net of any amount covered by insurance issued by a reputable and creditworthy insurer that has not contested coverage or reserved rights with respect to an underlying claim) in excess of $75.0 million or its foreign currency equivalent against Concentra or any Significant Subsidiary of Concentra, the failure by Concentra or such Significant Subsidiary, as applicable, to pay such judgment or decree, which judgment or decree has remained outstanding for a period of 60 days after such judgment or decree became final and nonappealable without being paid, discharged, waived or stayed;

(7)            except as permitted by this Indenture, any Note Guarantee of any Significant Subsidiary is declared to be unenforceable or invalid by any final and nonappealable judgment or decree or ceases for any reason to be in full force and effect, or any Guarantor that is a Significant Subsidiary or any Person acting on behalf of any Guarantor that is a Significant Subsidiary denies or disaffirms its obligations in writing under its Note Guarantee and such Default continues for 10 days after notice thereof is delivered to the Issuer by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class;

SECTION 6.02             Acceleration.

In the case of an Event of Default arising under clauses (8) or (9) of Section 6.01, all outstanding Notes shall become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

Upon any such declaration, the Notes shall become due and payable immediately. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes.

SECTION 6.03             Other Remedies.

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

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

SECTION 6.04             Waiver of Past Defaults.

Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. In case of any such waiver, the Issuer, the Trustee and the Holders shall be restored to their former positions and rights hereunder and under the Notes, respectively.

SECTION 6.05             Control by Majority.

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to reasonable indemnification against all losses and expenses caused by taking or not taking such action.

SECTION 6.06             Limitation on Suits.

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

(1)            such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2)            Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

(3)            such Holders have offered the Trustee reasonable security or indemnity reasonably satisfactory to it against any loss, liability or expense;

(4)            the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity; and

(5)            Holders of a majority in aggregate principal amount of the then outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

SECTION 6.07             Rights of Holders To Receive Payment.

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

SECTION 6.08             Collection Suit by Trustee.

If an Event of Default specified in clauses (1) or (2) of Section 6.01 or occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer and each Guarantor for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09             Trustee May File Proofs of Claim.

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

SECTION 6.10             Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

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

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

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

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

SECTION 6.11             Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

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

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

(1)            the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2)            in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions specifically required by any provision hereof to be furnished to it, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(c)            The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(a)            The Issuer shall pay to the Trustee from time to time reasonable compensation as agreed to between the Issuer and the Trustee for its acceptance of this Indenture and 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 promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b)            The Issuer shall indemnify the Trustee against any and all losses, liabilities, claims, damages or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense shall be determined to have been caused by its own negligence or willful misconduct. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel; provided that the Issuer shall not be required to pay such fees and expenses if it assumes the Trustee’s defense, and, in the Trustee’s reasonable judgment, there is no conflict of interest between the Issuer and the Trustee in connection with such defense. The Issuer shall not be required to pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

(c)            The obligations of the Issuer under this Section 7.07 shall survive the satisfaction and discharge of this Indenture.

Such Lien shall survive the satisfaction and discharge of this Indenture.

(e)            When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.08             Replacement of Trustee.

(a)            A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

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

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

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

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

(4)            the Trustee becomes incapable of acting.

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

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

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

(f)            A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07. 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.

ARTICLE 8.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01             Option To Effect Legal Defeasance or Covenant Defeasance.

The Issuer may, at any time, elect to have either Section 8.02 or 8.03 be applied to all outstanding Notes and all obligations of the Guarantors with respect to the Note Guarantees upon compliance with the conditions set forth below in this Article 8.

SECTION 8.02             Legal Defeasance and Discharge.

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.02, the Issuer and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth in Section 8.04 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 (including the Note Guarantees), which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, 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:

(1)            the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2)            the Issuer’s obligations with respect to such Notes under Sections 2.05, 2.06, 2.07, 2.08 and 4.02 hereof;

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

(4)            this Article 8.

Subject to compliance with this Section 8.02, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

SECTION 8.03             Covenant Defeasance.

Upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04, be released from each of their obligations under Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.15, 4.16, 4.17 and 4.18 and Section 5.01(a) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 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 and the Note Guarantees, 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 a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 of the option applicable to this Section 8.03 subject to the satisfaction of the conditions set forth in Section 8.04, Sections 6.01(4) through 6.01(7) and, to the extent relating to a Significant Subsidiary, 6.01(8) and 6.01(9) shall not constitute Events of Default.

SECTION 8.04             Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

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

(2)            in the case of Legal Defeasance, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and shall be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3)            in the case of Covenant Defeasance, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and shall be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4)            such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement (including, without limitation, the Credit Agreement) or instrument (other than this Indenture) to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound;

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

(6)            the Issuer must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

SECTION 8.05             Deposited Money and Government Securities To Be Held in Trust; Other Miscellaneous Provisions.

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

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

Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Issuer from time to time upon the request of the Issuer any money or non-callable Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04 hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.06             Repayment to Issuer.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

SECTION 8.07             Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of their obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the cash or Government Securities held by the Trustee or Paying Agent.

ARTICLE 9.

SECTION 9.01             Without Consent of Holders.

(a)            Notwithstanding Section 9.02 of this Indenture, the Issuer and the Trustee may amend or supplement this Indenture, the Note Guarantees or the Notes without the consent of any Holder of a Note:

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

(6)            to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date;

(7)            to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes, or to secure the Notes; or

(8)            to issue the Notes.

(b)            Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee shall join with the Issuer in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02             With Consent of Holders.

(a)            Except as provided below in this Section 9.02, the Issuer and the Trustee may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.10 and 4.15 hereof), the Note Guarantees and the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Note Guarantees or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes).

(b)            Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee shall join with the Issuer in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

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

(d)            After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the Notes then outstanding, voting as a single class, may waive compliance in a particular instance by the Issuer and the Guarantors with any provision of this Indenture, the Notes, or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2)            reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the optional redemption of the Notes contained in Section 5 of the Notes (except the notice period contained therein or in Sections 3.01, 3.02 and 3.03);

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

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

(7)            make any change in the preceding amendment and waiver provisions;

(8)            [Reserved.]; or

(9)            make any material change in the provisions of the Indenture or the Escrow Agreement described under Section 3.10.

SECTION 9.03             [Reserved].

SECTION 9.04             Revocation and Effect of Consents.

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

SECTION 9.05             Notation on or Exchange of Notes.

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

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

SECTION 9.06             Trustee To Sign Amendments, etc.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.03, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10.

NOTE GUARANTEES

SECTION 10.01             Guarantee.

(a)            Subject to this Article 10, from and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each of the Guarantors shall, jointly and severally, unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that:

(1)            the principal of, premium, if any, and interest on the Notes shall 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 shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2)            in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that same shall 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.

(b)            From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each of the Guarantors shall 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. From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each Guarantor shall waive 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 or by release in accordance with the provisions of this Indenture.

(c)            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 the Issuer or the Guarantors to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d)            From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each Guarantor shall agree 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. From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each Guarantor shall further agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 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 in the event of any declaration of acceleration of such Obligations as provided in Article 6, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, the Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

SECTION 10.02             Limitation on Guarantor Liability.

From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each 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 Guarantors, from and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, shall irrevocably agree that the obligations of such Guarantor shall be limited to the maximum amount that shall, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

SECTION 10.03             Execution and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01, each Guarantor shall agree that a notation of such Note Guarantee substantially in the form attached hereto as Exhibit D shall be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Guarantor by one of its Officers.

From and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, each Guarantor shall agree that its Note Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

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

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

In the event that Concentra or any of its Restricted Subsidiaries creates or acquires any Subsidiary after the date of this Indenture, if required by Section 4.18, Concentra shall cause such Subsidiary to comply with the provisions of Section 4.18 and this Article 10, to the extent applicable.

SECTION 10.04             Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in this Section 10.04, from and after the Assumption and upon execution and delivery of the Assumption Date Supplemental Indenture, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into another Person (other than either of the Issuer or another Guarantor) or consummate a Division as the Dividing Person (in each case, whether or not such Guarantor is the surviving Person), unless:

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

(2)            either:

(a)            the Person (if other than either of the Issuer or a Guarantor) acquiring the property in any such sale or disposition or the Person (if other than either of the Issuer or a Guarantor) formed by or surviving any such consolidation, merger or Division unconditionally assumes all the obligations of that Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under this Indenture and the Note Guarantee on the terms set forth herein or therein; or

(b)            except in the case of Concentra, such transaction does not violate Section 4.10.

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

Except as set forth in Articles 4 and 5, and notwithstanding clauses and above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation, merger or Division of a Guarantor with or into either of the Issuer 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.

SECTION 10.05             Releases.

The Note Guarantee of a Guarantor will be released:

(a)            except in the case of Concentra, in connection with any sale or other disposition of all of the assets of that Guarantor (including by way of merger, consolidation or Division) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary (other than a Non-Guarantor Subsidiary), if the sale or other disposition does not violate Section 4.10;

(b)            except in the case of Concentra, in connection with any sale of the Capital Stock of that Guarantor following which such Guarantor is no longer a Restricted Subsidiary, if the sale or other disposition does not violate Section 4.10;

(c)            if Concentra designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with Section 4.16 or a Non-Guarantor Subsidiary in accordance with the definition of that term;

(d)            except in the case of Concentra, if that Guarantor is released from its guarantee under the Credit Agreement; or

(e)            upon legal defeasance or covenant defeasance in accordance with Article 8 or satisfaction and discharge in accordance with Article 12.

If any Guarantor is released from its Note Guarantee, any of its Subsidiaries that are Guarantors will be released from their Note Guarantees, if any.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11.

SATISFACTION AND DISCHARGE

SECTION 11.01             Satisfaction and Discharge.

This Indenture shall be discharged and shall cease to be of further effect as to all Notes issued hereunder, when:

(1)            either:

(a)            all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or

(b)            all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or shall become due and payable within one year and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as shall be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(2)            no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit shall not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound;

(3)            the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

(4)            the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be.

In addition, the Issuer must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 shall survive. In addition, nothing in this Section 11.01 shall be deemed to discharge those provisions of Section 7.07, that, by their terms, survive the satisfaction and discharge of this Indenture.

SECTION 11.02             Application of Trust Money.

Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

To the extent that and so long as the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 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, the Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided, however, that if the Issuer has made any payment of principal of, premium, if any, or interest on any Notes following the reinstatement of their obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

The Escrow Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Escrow 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 (other than payment in full of all of the Obligations of the Escrow Issuer hereunder or under the Notes). The Escrow Guarantor hereby waives, to the fullest extent permitted by law, diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Escrow Issuer, any right to require a proceeding first against the Escrow Issuer, protest, notice and all demands whatsoever and covenants that the Escrow Guarantee shall not be discharged except by full payment of the obligations contained in the Notes and this Indenture or by release in accordance with the provisions of this Indenture.

SECTION 13.02             Continuing Obligation.

The Escrow Guarantor acknowledges that the Trustee has entered into this Indenture in reliance on this Article 13 being a continuous irrevocable agreement, and the Escrow Guarantor agrees that its guarantee may not be revoked in whole or in part and that its obligations hereunder shall terminate only in accordance with Section 13.06.

SECTION 13.04             Subordination.

The Escrow Guarantor covenants and agrees that all Indebtedness, claims and liabilities now or hereafter owing by the Escrow Issuer or any other guarantor to the Escrow Guarantor, whether arising hereunder or otherwise, are subordinated to the prior payment in full of the Escrow Guaranteed Obligations and are so subordinated as a claim against the Escrow Guarantor or any of its assets, whether such claim be in the ordinary course of business or in the event of voluntary or involuntary liquidation, dissolution, insolvency or bankruptcy, so that no payment with respect to any such Indebtedness, claim or liability will be made or received while any Event of Default exists.

SECTION 13.05             Assignment.

Within 30 days following any Change of Control, the Issuer shall mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b)            If the Issuer or a Restricted Subsidiary consummates any Asset Sales, within 10 Business Days of each date on which the aggregate amount of Excess Proceeds exceeds $60.0 million, the Issuer shall commence an Asset Sale Offer to all Holders and if the Issuer elects (or is required by the terms of such other pari passu indebtedness) any holders of other Indebtedness that is pari passu in right of payment with the Notes pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes and other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest to the Purchase Date in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer (or such Restricted Subsidiary) may use the remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase).

The Issuer shall pay interest semi-annually in arrears on January 15 and July 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”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be January 15, 2025. 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 at a rate that is the rate then in effect; 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 shall be computed on the basis of a 360-day year of twelve 30-day months.

(2)            METHOD OF PAYMENT. The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders at the close of business on the January 1 or July 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 shall be payable as to principal, interest and premium, if any, at the office or agency of the Paying Agent within the City and State of New York, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal of and interest, premium, if any, on, all Global Notes and all other Notes the Holder (if such Holder holds at least $1.0 million in aggregate principal amount of Notes) of which shall have provided wire transfer instructions to the Issuer prior to the record date. Payment of principal of, premium, if any, and interest on, Global Notes registered in the name of or held by DTC or any successor depositary or its nominee will be made by wire transfer of immediately available funds to such depositary or its nominee, as the case may be, as the registered Holder of such Global Note.
