 SECTION 103. Form of Documents Delivered to Trustee. In any case where
several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or
covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or
several documents. 
  
 Any certificate or opinion of an officer of
the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or

 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument. 
  
 SECTION 104. Acts of Holders;
Record Date. 
  
 (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent
duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of 

  

 33 

 
this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 

 
 (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or
writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date
of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 
  
 (c) The ownership of Securities shall be proved by the Notes Register. 
  
 (d) Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done,
omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
  
 (e) The Company may set any day as a record day for the purpose of determining the Holders of Outstanding Securities entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders; provided that the Company may not set a record date for, and the provisions of
this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities on
such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to
the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause
notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder in the manner set forth in Section 106. 
  
 The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to join in the giving or making of (i) any notice of Default, (ii) any declaration of acceleration referred to in Section 502, 

  

 34 

 
(iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512. If any record date is set pursuant
to this paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any
Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each
Holder in the manner set forth in Section 106. 
  
 With respect to
any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided
that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. 
  
 (f) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard
to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 
  
 (g) Notwithstanding any provision herein to the contrary, all Securities
issued under this Indenture shall vote and consent together on all matters (as to which the Holders may vote or consent) as one class and no series of Securities will have the right to vote or consent as a separate class on any matter. 

 
 SECTION 105. Notices, Etc., to Trustee and Company. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  
 (1) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing (which 

  

 35 

 
may be via facsimile) to or with the Trustee at its Corporate Trust Office at The Bank of New York, 101 Barclay Street, Fl. 8W, New York, New York 10286,
Attention: Corporate Trust Administration, or 
  
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the
address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company. 
  
 Notice to the Trustee shall not be effective until it is actually received by a Responsible Officer. 
  
 SECTION 106. Notice to Holders; Waiver. Where this Indenture provides
for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in
the Note Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver. 
  
 In
case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient
notification for every purpose hereunder. 
  
 SECTION 107.
Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be part of and govern this Indenture, the latter provision shall control.
If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may
be. 
  
 SECTION 108. Effect of Headings and Table of
Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
  
 SECTION 109. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether
so expressed or not. 
  

 36 

 SECTION 110. Separability Clause. In case any provision in this Indenture or in the Securities
shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
  
 SECTION 111. Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to
any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
  
 SECTION 112. Governing Law. This Indenture, the Securities and the Subsidiary Guarantees shall be governed by and
construed in accordance with the laws of the State of New York. 
  
 SECTION 113. Legal Holidays. In any case where any Interest Payment Date, Redemption Date, Purchase Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or
of the Securities) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date or
Purchase Date, or at the Stated Maturity; provided that to the extent such payment is made on such next succeeding Business Day, no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Purchase Date
or Stated Maturity, as the case may be. 
  
 SECTION 114. No
Personal Liability of Directors, Officers, Employees and Stockholders. No director, officer, employee, incorporator or stockholder of the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or the
Guarantors under the Securities, the Subsidiary Guarantees, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Securities.

 SECTION 301. Title and Terms. Except as set forth in the next paragraph, the aggregate principal amount of Securities which may be authenticated
and delivered under this Indenture is limited to $150,000,000 million, except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities pursuant to Section 304, 305, 306, 906 or
1108 or in connection with an Asset Sale Offer or Change of Control Offer pursuant to Sections 1015 or 1014, respectively. 
  
 After the Issue Date, the Company shall be entitled, subject to its compliance with Section 1008, to issue Additional Securities under this Indenture,
which Securities shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. All the Securities issued under this Indenture shall be treated as a single class for
all purposes of this Indenture. 
  
 With respect to any Additional
Securities, the Company shall set forth in a resolution of the Board of Directors, an Officers’ Certificate and a supplemental indenture pursuant to Section 901, a copy of each which shall be delivered to the Trustee, the following information:

  
 (1) the aggregate principal amount of such
Additional Securities to be authenticated and delivered pursuant to this Indenture and the provision of Section 1008 that the Company is relying on to issue such Additional Securities; 
  
 (2) the issue price, the issue date and the CUSIP number of such Additional Securities; provided,
however, that no Additional Securities may be issued at a price that would cause such Additional Securities 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 Securities shall
be Initial Securities or shall be issued in the form of Exchange Securities as set forth in Exhibit 2. 
  

 38 

 The Securities shall be known and designated as the “91⁄2% Senior Subordinated Notes due
2010” of the Company. 
  
 The Securities are general senior
subordinated unsecured obligations of the Company, are subordinated in right of payment to all existing and future Senior Indebtedness of the Company and shall rank senior or pari passu in right of payment to all existing and future
subordinated Indebtedness of the Company and are unconditionally guaranteed by the Guarantors. 
  
 Holders shall be entitled to the benefits of the Subsidiary Guarantees. The Subsidiary Guarantees are general unsecured obligations of each Guarantor, are subordinated in right of payment to all existing and future
Senior Indebtedness of each Guarantor, are pari passu in right of payment to the Guarantees of the Company’s 13% Senior Subordinated Notes and are senior or pari passu in right of payment to all existing and future subordinated
Indebtedness of each Guarantor. 
  
 If a Holder has given wire
transfer instructions to the Company, the Company shall make all principal, premium and interest payment on the Holder’s Securities in accordance with such instruction. All other payments of the principal of (and premium, if any) and interest
(and Additional Interest, if any) on the Securities shall be payable at the office or agency of the Paying Agent and Notes Registrar within the City and State of New York maintained for such purpose and at any other office or agency maintained by
the Company for such purpose; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Securities Register.

  
 The Company initially appoints the Trustee as the Paying Agent
and the Notes Registrar. The Company may change the Paying Agent or Notes Registrar without prior notice to the Holders, and the Company or any of its Subsidiaries may act as Paying Agent or Notes Registrar. The Company shall promptly notify the
Trustee in writing of the name and address of any Notes Registrar or Paying Agent not a party to this Indenture. 
  
 SECTION 302. Denominations. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 and any
integral multiple thereof. 
  
 SECTION 303. Execution,
Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President, its Chief Executive Officer or one of its Vice Presidents. The signature of any of these officers on the
Securities may be manual or facsimile. 
  
 Securities bearing the
manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such Securities. 
  

 39 

 At any time and from time to time after the execution and delivery of this Indenture, the Company may
deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall authenticate and deliver
such Securities as provided in this Indenture and not otherwise. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
  
 SECTION 304. Temporary Securities. Pending the preparation of
definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by
their execution of such Securities. 
  
 If temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the
temporary Securities at any office or agency of the Company designated pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities. 
  
 SECTION 305. Register; Transfer and
Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes
collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby
appointed “Notes Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
  
 The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a
Security is presented to the Notes Registrar with a request to register a transfer, the Notes Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(1) of the Uniform Commercial Code are met. When
Securities are 

  

 40 

 
presented to the Notes Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Notes Registrar
shall make the exchange as requested if the same requirements are met. The Securities shall be subject to the transfer and exchange provisions set forth in the Appendix. 
  
 SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the
Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor
and principal amount and bearing a number not contemporaneously outstanding. 
  
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
  
 Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security issued pursuant to this Section in lieu of any mutilated,
destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
  
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities. 
  
 SECTION 307. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security
(or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date immediately preceding such Interest Payment Date. 
  
 Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by 
  

 41 

 
virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2)
below: 
  
 (1) The Company may elect to make
payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more
than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at his address as it
appears in the Note Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the
Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
  
 (2) The Company may make payment of any Defaulted Interest
in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
  
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration or transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
  
 SECTION 308. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 309) interest (and Additional
Interest, if any) on 

  

 42 

 
such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary. 
  
 SECTION 309. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Notes Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and
deliver a certificate of such destruction to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the
Trustee for cancellation. 
  
 SECTION 310. CUSIP and ISIN
Numbers. The Company in issuing Securities may use “CUSIP” and “ISIN” numbers (if then generally in use) in addition to serial numbers; if so, the Trustee shall use such “CUSIP” and “ISIN” numbers in
addition to serial numbers in notices of redemption and repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such CUSIP and ISIN numbers either as printed on
the Securities or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Securities, and any such redemption or repurchase shall not be affected by
any defect in or omission of such CUSIP and ISIN numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers. 
  
 ARTICLE FOUR 
  
 Satisfaction and Discharge 
  
 SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly
provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when 
  
 (1) either 
  
 (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such
trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 
  

 43 

 (B) all such Securities not theretofore delivered to the Trustee for cancellation

  
 (i) have become due and payable, or

  
 (ii) shall become due and payable at their
Stated Maturity within one year, or 
  
 (iii)
are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
  
 and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and
premium, if any) and interest (and Additional Interest, if any) to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
  
 (2) the Company has paid or caused to be paid all other sums
payable hereunder by the Company; and 
  
 (3) the
Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

  
 Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402, the provisions of
Sections 303, 305 and 306 and the last paragraph of Section 1003 shall survive such satisfaction and discharge. 
  
 SECTION 402. Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee
pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company 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 (and Additional Interest, if any) for whose payment such money has been deposited with the Trustee.

assignment for the benefit of creditors, or the admission by the Company or any such Significant Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any such
Significant Subsidiary in furtherance of any such action. 

  
 In the event of a declaration of acceleration of the Securities because an Event of Default has occurred and is continuing as a result of the acceleration of any Indebtedness described in clause (6) of this Section
501, the declaration of acceleration of the Securities shall be automatically annulled if the holders of any Indebtedness described in clause (6) of this Section 501 have rescinded the declaration of acceleration in respect of such Indebtedness
within 30 days of the date of such declaration and if: 
  
 (a) the annulment of the acceleration of Securities would not conflict with any judgment or decree of a court of competent jurisdiction; and 
  
 (b) all existing Events of Default, except nonpayment of principal or interest on the Securities that became due solely because of the
acceleration of the Securities, have been cured or waived. 
  
 SECTION 502. Acceleration of Maturity; Rescission and Annulment. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities may declare the principal
of the Securities to be due and payable immediately; provided that so long as any Indebtedness permitted to be incurred pursuant to the Senior Credit Facilities shall be outstanding, such acceleration shall not be effective until the earlier
of: 
  

	 	(1)	 	an acceleration of any such Indebtedness under the Senior Credit Facilities, or 

  

	 	(2)	 	 five business days after receipt by the Company and the Credit Agent on the Issue Date (or to such other Credit Agent as the Trustee may hereafter be notified in
writing) of written notice of 

  

 47 

	 	 
such acceleration (provided that the notification of the replacement Credit Agent and its address shall be received by the Trustee prior to the
issuance of such notice of acceleration). 

  
 Notwithstanding the preceding paragraph, in the case of an Event of Default described in clause (9) or (10) of Section 501, with respect to the Company or any of its Significant Subsidiaries, the principal and unpaid interest on all
Outstanding Securities shall become due immediately without further action or notice. 
  
 In the case of any Event of Default occurs on or after August 15, 2007 by reason of any willful action or inaction taken or not taken by or on behalf of the Company with the intention of avoiding payment of the
premium that the Company would have had to pay if the Company then had elected to redeem the Securities pursuant to paragraph 5 of the Securities an equivalent premium shall also become and be immediately due and payable to the extent permitted by
law upon the acceleration of the Securities. If an Event of Default occurs prior to August 15, 2007 by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Securities prior to August 15, 2007, then, an additional premium shall also become immediately due and payable to the extent permitted by law upon acceleration of the Securities in an amount, for each of the years beginning on
August 15 of the years set forth below, as set forth below (such total amount due is expressed as a percentage of the principal amount of the Securities on the date of payment that would otherwise be due but for the provisions of this sentence):

  

	 Year

	  	Percentage

	 
	 2003
	  	109.500	%
	 2004
	  	108.313	%
	 2005
	  	107.126	%
	 2006
	  	105.939	%

  
 At any time after such
a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the
Outstanding Securities or the holders of a supermajority in aggregate principal amount of the Securities with respect to a default in respect of any provision requiring a supermajority for an amendment to such provision, as the case may be, by
written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on the Securities, (B) the
principal of (and premium, if any, on) any Securities which have become due otherwise than by such declaration of acceleration (including any Securities required to have been purchased on the Purchase Date pursuant to an offer to purchase made by
the Company) and interest thereon at the rate provided therefor in the Securities, (C) interest upon 
  

 48 

 
overdue interest at the rate provided therefor in the Securities and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and (2) all existing Events of Default, other than the non-payment of the principal of, premium, if any, and interest (and Additional Interest, if any) on the Securities
which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
  
 No such rescission shall affect any subsequent Default or impair any right consequent thereon. 
  
 SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

  
 The Company covenants that if 
  
 (1) Default is made in the payment of any interest (and
Additional Interest, if any) on any Security when such interest (and Additional Interest, if any) becomes due and payable and such Default continues for a period of 30 days, or 
  
 (2) Default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity
thereof or, with respect to any Security required to have been purchased pursuant to an Asset Sale Offer or Change of Control Offer made by the Company, at the Purchase Date thereof, 
  
 the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest (and Additional Interest, if any), and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and
on any overdue interest and Additional Interest, at the rate provided by the Securities, and, in addition thereto, 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. 
  
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or any other obligor upon the Securities, wherever situated. 
  
 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such judicial proceedings as the Trustee shall deem
appropriate, whether for the specific 

  

 49 

 
enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

  
 SECTION 504. Trustee May File Proofs of Claim. In case
of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable
on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized and directed by each Holder to make such payments
to the Trustee and, in the event that the Trustee requests the making of such payments directly to the Holders, is authorized and directed to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 
  
 No provision of this Indenture 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 Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a Trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
  
 SECTION 505. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this
Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
  
 SECTION 506. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest (or Additional Interest, if any), upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid: 
  
 FIRST: To the payment of all amounts due the Trustee under Section 607; 
  
 SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest (and Additional Interest, if
any) on 

  

 50 

 
the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according
to the amounts due and payable on such Securities for principal (and premium, if any) and interest (and Additional Interest, if any), respectively; and 
  
 THIRD: To the Company or to such party as a court of competent jurisdiction may direct. 
  
 SECTION 507. Limitation on Suits. No Holder of any Security shall have
any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
  
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default;

  
 (2) the Holders of not less than 25% in
principal amount of the Outstanding Securities shall have made written request to the Trustee institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  
 (3) such Holder or Holders have offered to the Trustee
indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; 
  
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
  
 (5) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities; 
  
 it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture
to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all the Holders. 
  
 SECTION 508.
Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the
principal of (and premium, if any) and (subject to Section 307) interest (and Additional Interest, if any) on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date or in
the case of an Asset Sale Offer or Change of Control Offer made by the Company and required to be accepted as to such Security, on the Purchase Date) and to institute suit for 

  

 51 

 
the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
  
 SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted. 
  
 SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or
remedy. 
  
 SECTION 511. Delay or Omission Not Waiver. No
delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
  
 SECTION 512. Control by Holders. The Holders of a majority in
aggregate principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee;
provided that: 
  
 (1) such direction
shall not be in conflict with any rule of law or with this Indenture or involve the Trustee in personal liability, and 
  
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
  
 SECTION 513. Waiver of Past Defaults. The Holders of not less than a
majority in aggregate principal amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any existing Default or Event of Default hereunder and its consequences hereunder, except 
  
  

 52 

 (1) a Default or Event of Default with respect to any provision requiring a supermajority
to amend, which Default or Event of Default may only be waived by such a supermajority, 
  
 (2) a continuing Default or Event of Default in the payment of the principal of (or premium, if any) or interest (or Additional Interest,
if any) on any Security (including any Security which is required to have been purchased pursuant to an Asset Sale Offer or Change of Control Offer which has been made by the Company), or 
  
 (3) a Default or Event of Default in respect of a covenant
or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security affected. 
  
 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 Event of Default or impair any right consequent thereon. 
  
 SECTION 514. 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, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs, including reasonable attorney’s fees and expenses,
against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Trustee or the Company. 
  
 SECTION 515. Waiver of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as
though no such law had been enacted. 
  
 ARTICLE SIX 
  
 The Trustee 
  
 SECTION 601. Certain Duties and Responsibilities. 
  
 (a) The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture 

  

 53 

 
shall require the Trustee to expend or risk own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so
provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to provisions of this Section. In case an Event of Default shall occur and be continuing, the
Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. 
  
 (b) Except during the continuance of a Default or an Event of Default: 
  
 (1) The Trustee need undertake to perform only those duties as are specifically set forth in this Indenture
and no covenants or obligations shall be implied in this Indenture against the Trustee. 
  
 (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 such certificates or opinions to determine whether or not they conform to the requirements of this Indenture. 
  
 (c) The Trustee shall have no liability except for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

  
 (1) This paragraph does not limit the effect
of paragraph (b) of this Section 601. 
  
 (2) The
Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. 
  
 (3) The Trustee shall not be liable with respect to any action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 512. 
  
 SECTION 602. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders a notice of the Default or Event of Default within 90 days after it
occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Security, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a
committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders. 
  
 SECTION 603. Certain Rights of Trustee.  
  

 54 

 Subject to the provisions of Section 601: 
  
 (a) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon

 (j) the rights, privileges, protections, immunities and
benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed by the

 SECTION 604. Not Responsible for
Recitals or Issuance of Securities. The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for

any Paying Agent, any Notes Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company with the same

combined capital and surplus of at least $50,000,000 and a Corporate Trust Office in the Borough of Manhattan, The City of New York. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
  
 SECTION 610. Resignation and Removal; Appointment of Successor. (a) No

for the appointment of a successor Trustee.

 (d) If at any time: 
  
 (1) the Trustee shall fail to comply with Section 608 after
written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its of property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, 
  
 then, in any such
case, (i) the Company by a Board Resolution may remove the Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the
successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for
at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  

 58 

 (f) The Company shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor Trustee to all Holders in the manner provided in Section 106. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 
  
 SECTION 611. Acceptance of Appointment by Successor. Every successor
Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and
trusts. 
  
 No successor Trustee shall accept its appointment
unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 
  
 SECTION 612. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder, provided that such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties
hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
  
 SECTION 613. Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company or any

 The Company may also from
time to time designate one or more other offices or agencies (in or outside the Borough of Manhattan, The City of New York) where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
  
 SECTION 1003. Money for Security Payments to be Held in Trust. If the Company shall at any time act as its own Paying
Agent, it shall, on or before each due date of the principal of (and premium, if any) or interest (and Additional Interest, if any) on any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal (and premium, if any) or interest (and Additional Interest, if any) so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of
its action or failure so to act. 
  
 Whenever the Company shall
have one or more Paying Agents, it shall, prior to each due date of the principal of (and premium, if any) or interest (and Additional Interest, if any) on any Securities, deposit with a Paying Agent a sum sufficient to pay the principal (and
premium, if any) or interest (and Additional Interest, if any) so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium, interest or Additional Interest, and (unless such Paying Agent is the
Trustee) the Company shall promptly notify the Trustee of its action or failure so to act. 
  
 The Company shall cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent shall: 
  
 (1) hold all
sums held by it for the payment of the principal of (and premium, if any) or interest (and Additional Interest, if any) on Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as herein provided;

the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
  
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums
held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such money. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest (and Additional Interest, if any) on any Security
and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of general circulation in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the

things necessary to preserve and keep in full force and effect their existence, rights (charter and statutory) and franchises; provided, however, that the Company and its Restricted Subsidiaries shall not be required to preserve any
such right or franchise if the Board of Directors of the Company in good faith shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company or its Restricted Subsidiaries and that the loss
thereof is not disadvantageous in any material respect to the Holders. 
  
 SECTION 1005. Maintenance of Properties. The Company shall cause all properties used or useful in the conduct of its business or the business of any Restricted Subsidiary of the Company to be maintained and kept in good condition,
repair and working order and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from 

  

 67 

 
discontinuing the operation or maintenance of any of such properties if such discontinuance is, as determined by the Board of Directors of the Company in
good faith, desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders. 
  
 SECTION 1006. Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any of its Restricted Subsidiaries or upon the income, profits or property of the Company or any of its Restricted Subsidiaries, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any of its Restricted Subsidiaries; provided, however, that the Company shall not be required to pay or discharge
or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings or where the failure to effect such payment is not adverse in any
material respect to the Holders. 
  
 SECTION 1007. Maintenance
of Insurance. The Company shall, and shall cause its Restricted Subsidiaries to, keep at all times all of their properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible or
in the case of insurance coverage, to self insure in each case to the extent, in the judgment of the Company, to do so comports with good business practice. 
  
 SECTION 1008. Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock. The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired
Debt) and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any Disqualified Stock or preferred stock; provided, however, that the Company may incur Indebtedness
(including Acquired Debt) or issue Disqualified Stock and the Company’s Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) and issue Disqualified Stock or preferred stock if the Fixed Charge Coverage Ratio for the
Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is
issued would have been at least 2.50 to 1; 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 preferred
stock, as applicable, had been issued, as the case may be, at the beginning of such four-quarter period. 
  
 The first paragraph of this Section 1008 shall not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted
Debt”): 
  
 (1) the incurrence by the
Company or any of its Restricted Subsidiaries of Indebtedness and letters of credit pursuant to the Senior Credit 

  

 68 

 
Facilities; provided that the aggregate amount of all Indebtedness of the Company and the Guarantors outstanding under the Senior Credit Facilities
after giving effect to such incurrence does not exceed an amount equal to $475.0 million at any one time; 
  
 (2) the incurrence by the Company and its Restricted Subsidiaries of Existing Indebtedness; 
  
 (3) the incurrence by the Company and the Guarantors of
Indebtedness represented by the Securities (other than any Additional Securities) and the Subsidiary Guarantees; 
  
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage
financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such
Restricted Subsidiary (whether through the direct purchase of assets or the Capital Stock of any Person owning such Assets), in an aggregate principal amount or accreted value, as applicable, not to exceed $15 million at any time outstanding;

  
 (5) the incurrence by the Company or any of
its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be
incurred under the first paragraph of this covenant or clauses (2), (3) or (14) of this Section 1008; 
  
 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any
of its Restricted Subsidiaries; provided, however, that: 
  
 (a) if the Company or any Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Securities, in the
case of the Company, or the Subsidiary Guarantee of such Guarantor, in the case of a Guarantor; and 
  
 (b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than
the Company or a Wholly Owned Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Wholly Owned Restricted Subsidiary shall be deemed, in each case, to constitute an
incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 
  

 69 

 (7) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging
Obligations that are incurred for the purpose of hedging interest rate risk with respect to any Indebtedness that is permitted by the terms of this Indenture to be outstanding; 
  
 (8) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a
Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Section 1008; 
  
 (9) the incurrence by the Company’s Unrestricted Subsidiaries of Non-Recourse Debt; provided, however, that if any such
Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was not permitted by this clause (9); 
  
 (10) Indebtedness incurred by the Company or any of its
Restricted Subsidiaries constituting reimbursement obligations with respect to letters of credit issued in the ordinary course of business, including without limitation in respect of workers’ compensation claims or self-insurance, or other
Indebtedness with respect to reimbursement type obligations regarding workers’ compensation claims; provided, however, that upon the drawing of such letters of credit or the incurrence of such Indebtedness, such obligations are
reimbursed within 30 days following such drawing or incurrence; 
  
 (11) Indebtedness arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection
with the disposition of any business, asset or Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Subsidiary for the purpose of financing such acquisition;
provided that (a) such Indebtedness is not reflected on the balance sheet of the Company or any Restricted Subsidiary (contingent obligations referred to in a footnote or footnotes to financial statements and otherwise reflected on the
balance sheet shall not deemed to be reflected on such balance sheet for purposes of this clause (a)) and (b) the maximum aggregate liability in respect of such Indebtedness shall at no time exceed the gross proceeds including non-cash proceeds (the
fair market value of such non-cash proceeds being measured at the time and without giving effect to any such subsequent changes in value) actually received by the Company and/or such Restricted Subsidiary in connection with such disposition;

  
 (12) obligations in respect of performance,
surety and similar bonds and completion guarantees provided by the Company or any Restricted Subsidiary in the ordinary course of business; 
  
 (13) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument (except in
the case of daylight overdrafts) drawn against insufficient funding in the ordinary course of business; 
  

 70 

 provided, however, that such Indebtedness is extinguished within five business days of
incurrence; and 
  
 (14) the incurrence by the
Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or
replace any other Indebtedness incurred pursuant to this clause (14), not to exceed $25 million. 
  
 For purposes of determining compliance with this Section 1008, in the event that an item of proposed Indebtedness meets the criteria of more than one of
the categories of Permitted Debt described in clauses (1) through (14) above or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company shall be permitted to classify such item of Indebtedness in any manner that
complies with this covenant. In addition, the Company may, at any time, change the classification of an item of Indebtedness (or any portion thereof) to any other clause or to the first paragraph hereof, provided that the Company would be
permitted to incur such item of Indebtedness (or the portion thereof) pursuant to such other clause or the first paragraph hereof, as the case may be, at such time of reclassification. Accrual of interest, accretion or amortization of original issue
discount and the accretion of accreted value shall not be deemed to be an incurrence of Indebtedness for purposes of this covenant. 
  
 SECTION 1009. Limitation on Restricted Payments. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly: 
  
 (1) declare or pay any dividend
or make any other payment or distribution on account of the Company’s or any its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment on such Equity Interests in connection with any merger or consolidation
involving the Company) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other
Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary of the Company); 
  
 (2) purchase, redeem or otherwise acquire or retire for value (including without limitation, in connection with any merger or
consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company or any Restricted Subsidiary of the Company (other than any such Equity Interests owned by the Company or any Restricted
Subsidiary of the Company); 
  
 (3) make any
payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness of the Company or any Guarantor that is subordinate or junior in right of payment to the Securities or any Subsidiary Guarantee, as
applicable, except scheduled payments of interest or principal at Stated Maturity thereof; or 
  

 71 

 (4) make any Restricted Investment (all such payments other actions set forth in clauses
(1) through (4) above being collectively referred to as “Restricted Payments”), 
  
 unless, at the time of and after giving effect to such Restricted Payment: 
  
 (1) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof; 
  
 (2) the Company would, after giving pro forma
effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
the first paragraph of Section 1008; and 
  
 (3)
such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Reference Date (excluding Restricted Payments permitted by clauses (1) through (6), (9), (12),
(14) and (15) of the next succeeding paragraph), is less than the sum, without duplication, of: 
  
 (a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the first full
fiscal quarter commencing after the Reference Date to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income
for such period is a deficit, less 100% of such deficit); plus 
  
 (b) 100% of the aggregate net proceeds (including the fair-market value of property other than cash; provided that fair market value of property other than cash shall be determined in good faith by the Board of
Directors whose Board Resolution with respect thereto shall be delivered to the Trustee and such determination must be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair
market value exceeds $35 million) received by the Company as a contribution to the Company’s capital or received by the Company from the issue or sale since the Reference Date of Equity Interests of the Company (other than Disqualified Stock)
or of Disqualified Stock or debt securities of the Company that have been converted subsequent to the Reference Date into such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Restricted Subsidiary
of the Company and other than Disqualified Stock or convertible debt securities that have been converted into Disqualified Stock); plus 
  

 72 

 (c) to the extent that any Restricted Investment in any Person that was made after the
Reference Date is sold for cash or otherwise liquidated or repaid for cash, or an Unrestricted Subsidiary is designated a Restricted Subsidiary, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost
of disposition, if any), or the portion (proportionate to the Company’s equity interest in such Subsidiary) of the fair market value of the net assets of such Unrestricted Subsidiary upon becoming a Restricted Subsidiary, as the case may be,
and (ii) the initial amount of such Restricted Investment made after the Reference Date in such Person or Unrestricted Subsidiary; plus 
  
 (d) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon the
conversion or exchange subsequent to the Reference Date of any Indebtedness of the Company convertible or exchangeable for Equity Interests (other than Disqualified Stock) of the Company (less the amount of any cash, or other property, distributed
by the Company or any Restricted Subsidiary upon such conversion or exchange); plus 
  
 (e) if any Unrestricted Subsidiary pays any cash dividends or cash distributions to the Company or any of its Restricted Subsidiaries,
100% of any such cash dividends or cash distributions made after the Reference Date. 
  
 So long as no Default has occurred and is continuing or would be caused thereby, the preceding provisions shall not prohibit: 
  

(1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would
have complied with the provisions of this Indenture; 
  
 (2) the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness or Equity Interests of the Company or any Restricted Subsidiary in exchange for, or out of the net cash proceeds of the
substantially concurrent sale or issuance (other than to a Subsidiary of the Company) of, other Equity Interests of the Company (other than Disqualified Stock); provided that the amount of any such net cash proceeds that are utilized for such
redemption, repurchase, retirement, defeasance or other acquisition shall be excluded from clause (3)(b) of the preceding paragraph; 
  
 (3) the defeasance, redemption, repurchase or other acquisition of Indebtedness of the Company or any Guarantor that is subordinate or
junior in right of payment to the Securities or any Subsidiary Guarantee, as applicable, with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; 
  

 73 

 (4) the payment of any dividend by a Restricted Subsidiary of the Company to the holders
of its Equity Interests on a pro rata basis regardless of whether any Default has occurred or is continuing; 
  
 (5) the redemption, repurchase, acquisition or retirement of Equity Interests in a Permitted Joint Venture of the Company or of any of the
Company’s Restricted Subsidiaries in accordance with the organizational documents for, and agreements among holders of Equity Interests in, such Permitted Joint Venture or Restricted Subsidiary, provided that as a result of such
redemption, repurchase, acquisition or retirement of Equity Interests in any such Permitted Joint Venture, any such Permitted Joint Venture shall become a Wholly Owned Restricted Subsidiary of the Company and a Guarantor under this Indenture;

  
 (6) the redemption, repurchase, acquisition
or retirement of Equity Interests in and Indebtedness of the Development Corporations in accordance with the respective securities purchase agreements entered into and notes issued by such Development Corporations; provided that as a result
of such redemption, repurchase, acquisition or retirement, such Development Corporations shall become Wholly Owned Restricted Subsidiaries of the Company and Guarantors under this Indenture; 
  
 (7) the purchase, redemption or other acquisition,
cancellation or retirement for value of Equity Interests of the Company or any Restricted Subsidiary of the Company or any parent of the Company held by any existing or former employees of the Company or Holdings or any Subsidiary of the Company or
their assigns, estates or heirs, in each case in connection with the repurchase provisions under employee stock option or stock purchase agreements or other agreements to compensate management employees; provided that such redemptions or
repurchases pursuant to this clause shall not exceed $2 million in any calendar year subsequent to the Reference Date with unused amounts in any calendar year being carried over to succeeding calendar years subject to a maximum of $10 million in any
calendar year; provided that the amount of any such payments will be included in calculations of the amount of Restricted Payments subsequent to the Reference Date; 
  
 (8) loans or advances to employees or directors of the Company or Holdings or any Subsidiary of the Company
made in the ordinary course of business subsequent to the Reference Date the proceeds of which are used to purchase Capital Stock of the Company or Holdings, in an aggregate amount not to exceed $5 million at any one time outstanding;
provided that the amount of any such payments will be included in calculations of the amount of Restricted Payments subsequent to the Reference Date; 
  
 (9) repurchases of Capital Stock subsequent to the Reference Date deemed to occur upon exercise of stock options if such Capital Stock
represents a portion of the exercise price thereof; 
  

 74 

 (10) if immediately before and immediately after giving effect thereto, no Default or
Event of Default has occurred and the Company would have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 1008, payments of cash dividends,
or loans or other payments, to Holdings in an amount sufficient to enable Holdings to make semi-annual payments after August 15, 2004 of cash interest not in excess of 14% per annum on the principal amount of Holdings Senior Discount Debentures (or
100 basis points higher if required to be made in respect of the Holdings Senior Discount Debentures in accordance with the terms thereof in effect on the Issue Date); provided that Holdings is otherwise unable to pay such interest and such
dividends, loans or other payments are applied directly to the payment of such interest; and provided further, that the amount of any such payments shall be included in calculations of the amount of Restricted Payments subsequent to
the Reference Date; 
  
 (11) if immediately
before and immediately after giving effect thereto no Default or Event of Default has occurred, payments subsequent to the Reference Date of principal, interest, premium (if any) or payment due upon redemption, repurchase, conversion, acquisition or
retirement of Holdings’ 6.0% Convertible Subordinated Notes due 2001 and 4.5% Convertible Subordinated Notes due 2003 in accordance with the respective terms thereof in effect on the Reference Date; provided that the amount of any such
payments shall be included in calculations of the amount of Restricted Payments subsequent to the Reference Date; 
  
 (12) payments to Holdings in an amount equal to the amount of income tax that the Company and the Restricted Subsidiaries would have paid
had they filed consolidated tax returns on a separate Company basis in any given year, less the amount of such taxes paid or to be paid directly by the Company and the Restricted Subsidiaries for such years; 
  
 (13) an amount not to exceed $1.0 million in any fiscal year
subsequent to the Reference Date to permit Holdings to pay: 
  
 (i) franchise taxes and other fees required to maintain its legal existence; and 
  
 (ii) its corporate overhead expenses incurred in the ordinary course of business, its audit expenses, any filing fees required by the
Commission and to pay salaries or other compensation of employees who perform services for both Holdings and the Company; 
  
 provided that the amount of any such payments will be included in calculations of the amount of Restricted Payments subsequent to the Reference
Date; 
  

 75 

 (14) Permitted Investments; 
  
 (15) distributions to fund the 1999 Transactions; and

  
 (16) other Restricted Payments subsequent to
the Reference Date in an aggregate amount not to exceed $5 million at any one time; provided that the amount of any such payments will be included in calculations of the amount of Restricted Payments subsequent to the Reference Date.

  
 The amount of all Restricted Payments (other than cash) shall
be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any
non-cash Restricted Payment shall be determined in good faith by the Board of Directors whose resolution with respect thereto shall be delivered to the Trustee. Not later than the date of making any Restricted Payment, the Company shall deliver to
the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 1009 were computed, together with a copy of any fairness opinion or
appraisal required by this Indenture. 
  
 SECTION 1010.
Limitations on Dividends and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to: 
  
 (1) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (i) on its Capital Stock or (ii)
with respect to any other interest or participation in, or measured by, its profits; 
  
 (2) pay any Indebtedness owed to the Company or any of the Company’s Restricted Subsidiaries; 
  
 (3) make loans or advances to the Company or any of the
Company’s Restricted Subsidiaries; or 
  
 (4) transfer any of its properties or assets to the Company or any of the Company’s Restricted Subsidiaries. 
  
 However, the preceding restrictions shall not apply to encumbrances or restrictions existing under or by reason of: 
  
 (1) any encumbrance or restriction pursuant to an agreement
in effect at or entered into on the Issue Date, including: 
  
 (a) the Senior Credit Facilities as in effect as of the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof, provided

  

 76 

 
that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken
as a whole (as determined in the good faith judgment of the Company’s Board of Directors), with respect to such dividend and other payment restrictions than those contained in the Senior Credit Facilities as in effect on the Issue Date; and

  
 (b) this Indenture and the Securities;

  
 (2) any applicable law, rule, regulation or
order; 
  
 (3) any instrument governing
Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness
was permitted by the terms of this Indenture to be incurred; 
  
 (4) customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices; 
  
 (5) any Purchase Money Note or other Indebtedness or contractual requirements incurred with respect to a
Qualified Receivables Transaction relating exclusively to a Receivables Entity that, in the good faith determination of the Board of Directors of the Company, are necessary to effect such Qualified Receivables Transaction; 
  
 (6) purchase money obligations for property acquired in the
ordinary course of business that impose restrictions on the property so acquired of the nature described in the last clause of the preceding paragraph; 
  
 (7) restrictions with respect solely to a Restricted Subsidiary of the Company imposed pursuant to a binding agreement which has been
entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Restricted Subsidiary; provided that such restrictions apply solely to the Capital Stock or assets being sold of such Restricted
Subsidiary; 
  
 (8) provisions with respect to
the disposition or distribution of assets or property in connection with Permitted Joint Ventures entered into in accordance with past practice made in the ordinary course of business; 
  
 (9) Permitted Refinancing Indebtedness, provided that the material restrictions contained in the
agreements governing such Permitted Refinancing Indebtedness are no more restrictive, in the good faith judgment of the Company’s Board of Directors, taken as a whole, to the Holders than those contained in the agreements governing the
Indebtedness being refinanced; and 
  

 77 

 (10) restrictions on cash or other deposits or net worth imposed by customers under
contracts entered into in the ordinary course of business. 
  
 Notwithstanding the foregoing, neither (a) customary provisions restricting subletting or assignment of any lease entered into in the ordinary course of business, consistent with industry practice, nor (b) Liens permitted under the terms of
this Indenture shall in and of themselves be considered a restriction on the ability of the applicable Restricted Subsidiary to transfer such agreement or assets, as the case may be. 
  
 SECTION 1011. Limitation on Liens Securing Indebtedness. The Company 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 securing trade payables or Indebtedness that does not constitute Senior Indebtedness (other than Permitted Liens) upon
any of their property or assets, now owned or hereafter acquired unless: 
  
 (1) in the case of Liens securing Indebtedness that is expressly subordinated or junior in right of payment to the Securities, the
Securities are secured on a senior basis to the obligations so secured until such time as such obligations are no longer secured by a Lien; and 
  
 (2) in all other cases, the Securities are secured on an equal and ratable basis with the obligations so secured until such time as such
obligations are no longer secured by a Lien. 
  
 SECTION 1012.
Limitation on Transactions With Affiliates. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate or any affiliated professional associations or
professional corporations which employ physicians and other professionals who provide healthcare services for the Company’s occupational and health services centers (each, an “Affiliate Transaction”), unless: 
  
 (1) such Affiliate Transaction is on terms that are no less
favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary made on an arm’s-length basis with an unrelated Person; and

  
 (2) the Company delivers to the Trustee:

  
 (a) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies
with clause (1) above and that such Affiliate 

  

 78 

 
Transaction has been approved by a majority of the disinterested members of the Board of Directors; and 
  
 (b) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of $15 million, an opinion as to the fairness to the holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment
banking firm of national standing. 
  
 The following items shall
not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of the prior paragraph: 
  
 (1) customary directors’ fees to Persons who are not otherwise Affiliates of the Company; 
  
 (2) transactions between or among the Company and/or its
Restricted Subsidiaries; 
  
 (3) the payment of
Affiliate Management Fees in an amount in any calendar year not to exceed the greater of (a) $1 million and (b) 1% of Consolidated EBITDA; 
  
 (4) payments by the Company or any of its Restricted Subsidiaries to Welsh Carson, Ferrer Freeman and their respective Affiliates made for
any financial advisory, financing, underwriting or placement services or in respect of other investment banking activities, including, without limitation, in connection with acquisitions or divestitures, which payments are approved in good faith by
a majority of the Board of Directors of the Company or a committee thereof consisting of disinterested members; 
  
 (5) loans or advances to employees in accordance with past practice made in the ordinary course of business which are approved in good
faith by a majority of the Board of Directors of the Company or a committee thereof consisting of disinterested members; 
  
 (6) any agreement as in effect on the Issue Date or any amendment thereto (so long as any such amendment is no less favorable to the
Company and its Restricted Subsidiaries); 
  
 (7)
any payment pursuant to any tax sharing agreement between the Company and Holdings or any other Person with which the Company is required or permitted to file a consolidated tax return or with which the Company is or could be part of a consolidated,
combined or unitary group for tax purposes; provided that in no event shall the amount permitted to be paid pursuant to all such agreements exceed the tax liabilities attributable solely to the Company and its Restricted Subsidiaries (whether
as a consolidated, combined or unitary group); 
  

 79 

 (8) Restricted Payments that are permitted by Section 1009; 
  
 (9) customary fees and compensation paid to, and indemnity
provided on behalf of, officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries; 
  
 (10) any transaction involving ordinary course investment banking, merchant banking, commercial banking or related activities; and

  
 (11) issuances or sales by the Company of
Equity Interests (other than Disqualified Stock) or any contribution to the capital of the Company or any Restricted Subsidiary. 
  
 Notwithstanding the foregoing, the Holders will be entitled to receive payment in full in cash of all amounts due or to become due in respect of the
Securities before any payment is made with respect to Affiliate Management Fees in the event of any distribution to creditors of the Company in any Insolvency or Liquidation Proceeding with respect to the Company. No payments of Affiliate Management
Fees shall be made by the Company or any of its Restricted Subsidiaries if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately
preceding the date on which Affiliate Management Fees are to be paid is less than 1.75 to 1; provided, however, that such payments due but not paid shall accrue and shall be paid only after such time as the Fixed Charge Coverage Ratio
for a four full fiscal quarter period is no longer less than or equal to 1.75 to 1. 
  
 For the avoidance of doubt, in connection with any transaction between Holdings and the Company, a member of the Board of Directors of the Company shall not cease to be a disinterested director solely because such
director also serves on the board of directors of Holdings. 
  
 SECTION 1013. Limitation on Issuances and Sales of Equity Interests in Restricted Subsidiaries. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of
any Equity Interests in any Restricted Subsidiary or to issue any of its Equity Interests (other than, if necessary, Equity Interests constituting directors’ qualifying shares) to any Person except: 
  
 (1) to the Company or a Wholly Owned Subsidiary (other than
a Receivables Entity); or 
  
 (2) in compliance
with Section 1015 and immediately after giving effect to such issuance or sale, such Restricted Subsidiary would continue to be a Restricted Subsidiary. 
  
 Notwithstanding the preceding paragraph, the Company may sell all the Equity Interests of a Restricted Subsidiary as long as the Company complies with
Section 1015.

 SECTION 1014. Repurchase of Securities at the Option of the Holder Upon a Change of Control.

  
 (1) Upon the occurrence of a Change of
Control, each Holder shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Securities pursuant to the offer described below (the “Change of Control
Offer”) at an offer price in cash equal to 101% of the aggregate principal amount of repurchased Securities plus accrued and unpaid interest and Additional Interest thereon, if any, to the Purchase Date (the “Change of Control
Payment”). Within 60 Business Days following any Change of Control, the Company shall mail a notice to each Holder stating: 
  

	 	(a)	 	that the Change of Control Offer is being made pursuant to this Section 1014 and that all Securities tendered shall be accepted for payment; 

  

	 	(b)	 	that the Change of Control Offer shall remain open for 20 Business Days; 

  

	 	(c)	 	the Purchase Price and the Purchase Date; 

  

	 	(d)	 	that any Security not tendered shall continue to accrue interest; 

  

	 	(e)	 	that, unless the Company defaults in the payment of the Change of Control Payment, all Securities accepted for payment pursuant to the Change of Control Offer shall cease to accrue
interest after the Purchase Date; 

  

	 	(f)	 	that Holders electing to have any Securities purchased pursuant to a Change of Control Offer shall be required to surrender the Securities, with the form entitled “Option of
Holder to Elect Purchase” on the reverse of the Securities completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Purchase Date; 

  

	 	(g)	 	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 Purchase Date,
a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Securities delivered for purchase and a statement that such Holder is withdrawing his election to have the Securities purchased; and

  

 81 

	 	(h)	 	that Holders whose Securities are being purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered,
which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. 

  
 The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
such laws and regulations are applicable in connection with the repurchase of the Securities 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 this Indenture relating to such Change of Control
Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 
  
 (2) By 12:00 p.m. (noon) Eastern Time on the Purchase Date,
the Company shall, to the extent lawful: 
  

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

  

	 	(b)	 	deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions thereof so tendered; and 

  

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

  
 The Paying Agent shall promptly mail to each Holder of Securities so tendered the Change of Control Payment for such Securities, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book
entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each such new Security shall be in a principal amount of $1,000 or an integral multiple thereof.
The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Purchase Date. 
  
 (3) If the Purchase Date hereunder is on or after an interest payment Regular Record Date and on or before the associated Interest Payment
Date, any accrued and unpaid interest (and Additional Interest, if any) due on such Interest Payment Date shall be paid to the Person in whose name a Security is registered at the close of business on such Regular Record Date, and such interest (and
Additional Interest, if applicable) shall not be payable to Holders who tender the Securities pursuant to such Change of Control Offer. 
  

 82 

 (4) Prior to making a Change of Control Offer pursuant to paragraph (1), but in any event
within 90 days following such Change of Control, the Company shall either (i) obtain any required consents, if any, under all agreements governing outstanding Senior Indebtedness to permit the making of the Change of Control Offer and the purchase
of Securities pursuant to this Section 1014, or (ii) repay all or a portion of the outstanding Senior Indebtedness to the extent necessary (including, if necessary, payment in full of such Indebtedness and payment of any prepayment premiums, fees,
expenses or penalties) to permit the repurchase of the Securities pursuant to this Section 1015 without such consent. 
  
 (5) The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of
Control Payment Date. 
  
 (6) The provisions
described above that require the Company to make a Change of Control Offer following a Change of Control will be applicable regardless of whether or not any other provisions of the Indenture are applicable. Except as described above with respect to
a Change of Control, the Company is not required to make mandatory repurchases or redemptions of the Securities in the event of a takeover, recapitalization or similar transaction. 
  
 (7) Notwithstanding anything to the contrary in this Section 1014, the Company shall not be required to make
a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 1014 hereof and all other provisions of
this Indenture applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer. 
  
 (8) The provisions of this Section 1014 relating to the Company’s obligation to make a Change of
Control Offer may be waived or modified with the consent of the Holders of a majority in principal amount of the Securities. 
  
 SECTION 1015. Repurchase of Securities at the Option of the Holder Upon an Asset Sale. The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless: 
  

	 	(1)	 	the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets or Equity
Interests issued or sold or otherwise disposed of; 

  

	 	(2)	 	such fair market value is determined by the Company’s Board of Directors and evidenced by a resolution of the Board of Directors set forth in an Officers’ Certificate
delivered to the Trustee; and 

  

 83 

	 	(3)	 	at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of
the following shall be deemed to be cash: 

  

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

  

	 	(b)	 	any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are contemporaneously (subject to ordinary settlement
periods) converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash received in that conversion); and 

  

	 	(c)	 	any Permitted Business Assets (so long as such Permitted Business Assets are acquired for fair market value, as determined in good faith by the Board of Directors of the Company, in
connection with the transaction giving rise to such Asset Sale; provided that the Board of Directors’ determination must be based on an opinion or appraisal issued by an independent accounting, appraisal or investment baking firm of
national standing if such fair market value exceeds $25 million), which Permitted Business Assets shall be deemed to have been acquired pursuant to the second succeeding paragraph in connection with such Asset Sale. 

  
 The 75% limitation referred to 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 preceding sentence, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the
75% limitation. 
  
 Within 365 days after the receipt of any Net
Proceeds from an Asset Sale, the Company or any such Restricted Subsidiary may apply such Net Proceeds, at its option: 
  
 (1) to repay or repurchase Senior Indebtedness of the Company or any Restricted Subsidiary; 
  

 84 

 (2) to the extent any proceeds remain after the prepayment of all outstanding Senior
Indebtedness, if any, that is prepayable at the option of the Company or such Restricted Subsidiary, to repay or repurchase the Company’s 13% Senior Subordinated Notes pursuant to the terms of the “Asset Sales” covenant in the
indenture governing the 13% Senior Subordinated Notes; 
  
 (3) to acquire all or substantially all the assets of, or a majority of the Voting Stock of, another Permitted Business; 
  
 (4) to make a capital expenditure in a Permitted Business; 
  
 (5) to acquire other assets (other than securities) that are used or useful in a Permitted Business; or

  
 (6) to make an Asset Sale Offer, treating the
Net Proceeds as Excess Proceeds for all purposes. 
  
 Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph shall constitute “Excess Proceeds”. When the aggregate amount of Excess Proceeds exceeds $15 million, the Company shall be required to make
an offer to all Holders of Securities (an “Asset Sale Offer”) and other pari passu Indebtedness of the Company or any Guarantor (other than the 13% Senior Subordinated Notes) to the extent required pursuant to the terms of that
pari passu Indebtedness to purchase the maximum principal amount of such Securities or other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer shall be equal to 100% of
the principal amount (or, in the case of such other pari passu Indebtedness that issued with significant original issue discount, 100% of the accreted value thereof) plus accrued and unpaid interest, if any, to the Purchase Date, and shall be
payable in cash (or in the case of such pari passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such other pari passu Indebtedness). If any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Company may use such Excess Proceeds for general corporate purposes. If the aggregate principal amount of Securities tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Securities to be
purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 
  
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
such laws and regulations are applicable in connection with the repurchase of the Securities as a result of an Asset Sale Offer. 
  
 To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to such Asset Sale Offer,
the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. 
  

 85 

 SECTION 1016. Investment Company. The Company shall not, and shall not permit any of its
Subsidiaries to, be required to register as an “Investment Company” (as that term is defined in the Investment Company Act of 1940, as amended), or otherwise become subject to registration under the Investment Company Act. 

  
 SECTION 1017. Limitations on Issuances of Guarantees of
Indebtedness. The Company shall not permit any Restricted Subsidiary, directly or indirectly, to incur Indebtedness or Guarantee or pledge any assets to secure the payment of any Indebtedness of the Company or any Restricted Subsidiary unless
either such Restricted Subsidiary (1) is a Guarantor or (2) simultaneously executes and delivers a supplemental indenture to this Indenture and becomes a Guarantor, which Guarantee shall (a) with respect to any Guarantee of Senior Indebtedness, be
subordinated in right of payment on the same terms as the Securities are subordinated to such Senior Indebtedness and (b) with respect to any Guarantee of any other Indebtedness, be senior to or pari passu with such Restricted
Subsidiary’s other Indebtedness or Guarantee of or pledge to secure such other Indebtedness. 
  
 Notwithstanding the preceding paragraph, any Subsidiary Guarantee of the Securities shall provide by its terms that it shall be automatically and
unconditionally released and discharged: 
  
 (1)
in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) if the Company applies the Net Proceeds of that sale or other disposition in accordance with
the applicable provisions of this Indenture; or 
  
 (2) in connection with the sale of all of the Capital Stock of a Guarantor if the Company applies the Net Proceeds of that sale in accordance with the applicable provisions of this Indenture; or 
  
 (3) if the Company designates such Restricted Subsidiary
that is a Guarantor as an Unrestricted Subsidiary. 
  
 SECTION
1018. Additional Guarantees. If (a) the Company shall acquire or create a Domestic Restricted Subsidiary (other than a Permitted Joint Venture or a Receivables Entity) after the Issue Date, or (b) any Subsidiary of the Company becomes (1) a
Domestic Restricted Subsidiary (other than a Permitted Joint Venture or a Receivables Entity) or (2) guarantees any Indebtedness of the Company or a Domestic Restricted Subsidiary, then, in each case, such newly acquired or created Restricted
Subsidiary or such other Subsidiary, as the case may be, shall become a Guarantor and execute a supplemental indenture that subjects such Person to the provisions of this Indenture as a Guarantor and the Company shall deliver an Opinion of Counsel
to the Trustee, in accordance with the terms of this Indenture, stating that such supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this Indenture constitute valid, legal, binding and enforceable
obligations of such Person (subject to customary exceptions concerning creditors’ rights and to equitable principles as may be acceptable to the Trustee). 
  

 86 

 SECTION 1019. Limitation on Lines of Business. The Company shall not, and shall not permit any
Restricted Subsidiary to, engage in any business other than a Permitted Business. 
  
 SECTION 1020. Anti-Layering. The Company shall not, and shall not permit any Guarantor to, incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is both: 
  
 (1) subordinate or junior in right of payment to any Senior
Indebtedness; and 
  
 (2) senior in any respect
in right of payment to the Securities. 
  
 No Guarantor shall
incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is both: 
  
 (1) subordinate or junior in right of payment to any Senior Indebtedness of such Guarantor; and 
  
 (2) senior in any respect in right of payment to the
Subsidiary Guarantees. 
  
 SECTION 1021. [NOT USED]

  
 SECTION 1022. [NOT USED] 
  
 SECTION 1023. Designation of Restricted and Unrestricted Subsidiaries.
The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, all outstanding
Investments owned by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments made at the time of such designation (to the extent not designated a
Permitted Investment) and shall reduce the amount available for Restricted Payments under the first paragraph of Section 1009. All such outstanding Investments shall be valued at their fair market value at the time of such designation, as determined
in good faith by the Board of Directors. That designation shall only be permitted if such Restricted Payment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of
Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default. 
  
 SECTION 1024. Advances to Subsidiaries. All advances to Restricted Subsidiaries made by the Company after the Issue Date shall be evidenced by
intercompany notes in favor of the Company substantially in the form of Exhibit B. Each intercompany note shall be payable upon demand and shall bear interest at the same rate as the Securities. 
  

 87 

 SECTION 1025. Payments for Consents. The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities
unless such consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
  
 SECTION 1026. Statement by Officers as to Default; Compliance
Certificates. (a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the
performance and observance of any of the terms, provisions and conditions of Section 801 or Sections 1004 to 1025, inclusive, and if the Company shall be in default, specifying all such Defaults and the nature and status thereof of which they may
have knowledge. 
  
 (b) The Company shall deliver to the Trustee,
as soon as possible and in any event within 10 days after the Company becomes aware or should reasonably become aware of the occurrence of a Default or an Event of Default, an Officers’ Certificate setting forth the details of such Default or
Event of Default, and the action which the Company proposes to take with respect thereto. 
  
 (c) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the Company shall deliver to the Trustee within 90 days after the end of each fiscal year a
written statement by the Company’s independent public accountants stating (A) that their audit examination has included a review of the terms of this Indenture and the Securities as they relate to accounting matters, and (B) whether, in
connection with their audit examination, any Default has come to their attention and, if such a Default has come to their attention, specifying the nature and period of the existence thereof. 
  
 SECTION 1027. Waiver of Covenants. The Company may omit in any
particular instance to comply with any covenant or condition set forth in Section 801 and Sections 1004 to 1025, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities shall, by
Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect; provided, however, with respect to any provision
requiring a supermajority approval to waive, such provision may only be waived by such a supermajority, and with respect to a covenant or provision which cannot be modified or amended without the consent of the Holder of each outstanding Security
affected, such provision may only be waived by the consent of each and every Holder of outstanding Security affected.

 The Trustee shall promptly notify the Company and each Notes Registrar in writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be redeemed. 
  
 Securities and portions of Securities selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Securities of a Holder are to be redeemed, the entire outstanding amount of
Securities held by such Holder, even if not a multiple of $1,000, shall be redeemed. 
  
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any 
  

 89 

 Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has
been or is to be redeemed.

 (1) the Redemption Date; 
  
 (2) the Redemption Price; 
  
 (3) if less than all the Outstanding Securities are to be
redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed, and in the case of partial redemption, a statement to the effect that upon surrender of such Securities, a new
Security in a principal amount equal to the unredeemed portion thereof shall be issued upon cancellation of the original Security;

 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company if the Company gives notice to
the Trustee at least 45 days prior to the Redemption Date (unless shorter notice shall be acceptable to the Trustee). 
  
 Notices of redemption may not be conditional. 
  
 SECTION 1106. Deposit of Redemption Price. Prior to 11:00 a.m. Eastern Time on any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) any applicable accrued interest and Additional Interest on, all the Securities which are to be redeemed on that date. The Trustee or the Paying Agent shall no later than 30 days after the expiration of the Redemption Date return to the
Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the Redemption Price of, and any applicable accrued interest and Additional Interest on, all Securities to be redeemed.

  

 90 

 SECTION 1107. Securities Payable on Redemption Date. Notice of redemption having been given as
aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and
any applicable accrued interest) such Securities or portions of them called for redemption shall not bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with any applicable accrued interest and Additional Interest to (but excluding) the Redemption Date; provided, however, that installments of interest whose Interest Payment Date is on or prior to the Redemption Date shall
be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. 
  
 If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate provided by the Security. 
  
 SECTION 1108. Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the
Company designated for that purpose pursuant to Section 1002 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

 SECTION 1201. Company’s Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at its option and at any time, by Board
Resolution elect to have either Section 1202 or 1203 hereof be applied with respect to the Outstanding Securities upon compliance with the conditions set forth below in this Article Twelve. 
  
 SECTION 1202. Legal Defeasance and Discharge. Upon the Company’s
exercise of the option provided in Section 1201 applicable to this Section, the Company shall be deemed to have been discharged from its obligations with respect to the Outstanding Securities and the Guarantors shall be deemed to have been
discharged from their obligations under the Subsidiary Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company and the Guarantors
shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Securities and to 
  

 91 

 have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are
concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except as to (i) rights of Holders to receive payments in respect of the principal of, premium, if any, and interest (and Additional
Interest, if any) on such Securities when such payments are due from the trust funds; (ii) the Company’s obligations with respect to such Securities concerning Sections 304, 305, 306, 1002 and 1003; (iii) the rights, powers, trust, duties, and
immunities of the Trustee, and the Company’s obligations in connection therewith; and (iv) the Legal Defeasance provisions of this Article Twelve, all of which shall survive until otherwise terminated or discharged hereunder. Subject to
compliance with this Article Twelve, the Company may exercise its option under this Section 1202 notwithstanding the prior exercise of its option under Section 1203. 
  
 SECTION 1203. Covenant Defeasance. Upon the Company’s exercise of the option provided in Section 1201 applicable
to this Section, the Company may, at its option and at any time, elect to have the obligations of the Company and the Guarantors released with respect to its (i) obligations under Sections 1005 through 1025, inclusive, and clause (4) of Section 801
and (ii) the occurrence of an event specified in Sections 501(5), (with respect to any of Sections 1005 through 1025, inclusive), 501(6) and 501(7) shall not be deemed to be a Default or an Event of Default on and after the date the conditions set
forth below are satisfied (hereinafter, “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth
in any such Section or clause, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or clause or by reason of any reference in any such Section or clause to any other provision herein or in any other
document, but the remainder of this Indenture and such Securities shall be unaffected thereby. 
  
 SECTION 1204. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 1202 or Section 1203 to the then Outstanding Securities: 
  
 (1) the Company shall irrevocably have deposited or caused
to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as shall be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest, Additional Interest,
if any, on the Outstanding Securities on the Stated Maturity of the Securities or on the applicable Redemption Date, as the case may be, and the Company must specify whether the Securities are being defeased to maturity or to a particular Redemption
Date; 
  
 (2) in the case of an election of Legal
Defeasance under Section 1202, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (a) the 
  

 92 

 Company 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, subject to customary assumptions and exclusions, the Holders of
the Outstanding Securities 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 an election of Covenant Defeasance under Section 1203, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that, subject to customary assumptions and exclusions, the Holders of the Outstanding Securities 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) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit); 
  
 (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or
any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; 
  
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company or with the
intent of preferring the Holders over the other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; 
  
 (7) no event which is, or after notice or lapse of time or both would become, an Event of Default with
respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in paragraphs (7) or (8) of Section 501, at any time on or prior to the 90th day after
the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day); and 
  
 (8) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, which opinion may be subject
to customary assumptions and exclusions, each stating that all conditions precedent provided for relating to either the Legal Defeasance under Section 1202 or the 
  

 93 

 Covenant Defeasance under Section 1203 (as the case may be) have been complied with. 
  
 SECTION 1205. Deposited Money and U.S. Government Obligations to be Held
in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 1204 in respect
of the Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal (and premium, if any) and interest (and Additional Interest, if any), but such money need not be segregated
from other funds except to the extent required by law. 
  
 The
Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1204 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 Securities. 
  
 Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request
any money or U.S. Government Obligations held by it as provided in Section 1204 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
  
 SECTION 1206. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 1202 or 1203 by reason of
any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if a Default from a bankruptcy or insolvency event occurs at any time during the period ending on the 91st day after
the date of a deposit by the Company hereunder, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article Twelve until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1202 or 1203; provided, that if the Company makes any payment of principal of (and premium, if any) or interest (and Additional Interest, if any) on any
Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or the Paying Agent. 
  

 94 

 ARTICLE THIRTEEN 
  

Subordination 
  
 SECTION 1301. Agreement to Subordinate. The Company agrees, and each Holder by accepting a Security agrees, that the Indebtedness evidenced by the
Securities and all Obligations in respect of the Securities (including but not limited to Additional Interest) are subordinated in right of payment, to the extent and in the manner provided in this Article Thirteen, to the prior payment in full in
cash of all Senior Indebtedness (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Indebtedness. 
  
 SECTION 1302. Liquidation; Dissolution; Bankruptcy. Upon any
distribution of assets of the Company upon any Insolvency or Liquidation Proceeding: 
  
 (1) the holders of all Senior Indebtedness of the Company shall be entitled to receive payment in full in cash or Cash Equivalents before
the Holders shall be entitled to receive any payment on account of the principal of, premium, if any, and interest on the Securities or any Obligation in respect to the Securities (except that Holders may receive (i) Reorganization Securities and
(ii) payments made from any defeasance trust created pursuant to Section 1201 hereof); and 
  
 (2) any payment or distribution of assets of the Company of any kind or character from any source, whether in cash, property or securities
(other than (i) Reorganization Securities and (ii) payments made from any defeasance trust created pursuant to Section 1201 hereof), to which the Holders or the Trustee on behalf of the Holders would be entitled (by set-off or otherwise), except for
this Article, shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, or by the Holders or by the Trustee if received by them, directly to the holders of
Senior Indebtedness (pro rata to such holders on the basis of the amounts of Senior Indebtedness held by such holders) or their Representative or Representatives, as their interests may appear, for application to the payment of the Senior
Indebtedness remaining unpaid until all such Senior Indebtedness has been paid in full in cash, after giving effect to any concurrent payment, distribution or provision therefor to or for the holders of Senior Indebtedness. 
  
 SECTION 1303. Default on Senior Indebtedness. (a) In the event of and
during the continuation of any default in the payment of principal of, interest or premium, if any, on any Senior Indebtedness, or any Obligation owing from time to time under or in respect of Senior Indebtedness, or in the event that any event of
default (other than a payment default) with respect to any Senior Indebtedness shall have occurred and be continuing and shall have resulted in such Senior Indebtedness becoming or being declared due and payable prior to the date on which it would
otherwise have become due and payable, then no payment shall be made by or on behalf of the Company on account of principal of, premium, if any, and interest (and Additional Interest, if any) on the 
  

 95 

 Securities (other than payments in the form of Reorganization Securities), unless and until such default shall have been
cured or waived in writing in accordance with the instruments governing such Senior Indebtedness or such acceleration shall have been rescinded or annulled; 
  
 (b) If any event of default other than as described in clause (a) above with respect to any Designated Senior Indebtedness
shall have occurred and be continuing permitting the holders of such Designated Senior Indebtedness (or their Representative or Representatives) to declare such Designated Senior Indebtedness due and payable prior to the date on which it would
otherwise have become due and payable, then no payment shall be made by or on behalf of the Company on account of the principal of, premium, if any, and interest (and Additional Interest, if any) on the Securities (other than payments in the form of
Reorganization Securities) during the period (a “Payment Blockage Period”) commencing on the date the Company or the Trustee receives written notice (a “Payment Notice”) of such event of default (which notice shall be binding on
the Trustee and the Holders as to the occurrence of such a payment default or nonpayment event of default) from the Credit Agent (or other holders of Designated Senior Indebtedness or their Representative or Representatives) and ending on the
earliest of: 
  
 (A) 179 days after such date;

  
 (B) the date, if any, on which such
Designated Senior Indebtedness to which such default relates is paid in full in cash or such default is cured or waived in writing in accordance with the instruments governing such Designated Senior Indebtedness by the holders of such Designated
Senior Indebtedness; and 
  
 (C) the date on
which the Trustee receives written notice from the Credit Agent (or other holders of Designated Senior Indebtedness or their Representative or Representatives), as the case may be, terminating the Payment Blockage Period, unless the maturity of any
Designated Senior Indebtedness has been accelerated. 
  
 (c)
During any consecutive 360-day period, the aggregate of all Payment Blockage Periods shall not exceed 179 days and there shall be a period of at least 181 consecutive days in each consecutive 360-day period when no Payment Blockage Period is in
effect. No event of default which existed or was continuing with respect to the Senior Indebtedness for which notice commencing a Payment Blockage Period was given on the date such Payment Blockage Period commenced shall be or be made the basis for
the commencement of any subsequent Payment Blockage Period unless such event of default is cured or waived for a period of not less than 90 consecutive days. 
  

 96 

 SECTION 1304. Acceleration of Securities. If payment of the Securities is accelerated because of
an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the acceleration. 
  
 SECTION 1305. When Distribution Must be Paid Over. In the event that, notwithstanding the other provisions of this Article Thirteen, the Trustee
receives any payment or distribution in respect of the Securities or of any Obligations with respect to the Securities at a time when the Trustee has received notice in accordance with Section 1310 that such payment or distribution is prohibited by
Section 1303 hereof, such payment or distribution shall be held by the Trustee in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to, the holders of Senior Indebtedness remaining unpaid or unprovided
for or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments representing any of such Senior Indebtedness may have been issued, ratably according to aggregate principal amounts
remaining unpaid on account of such Senior Indebtedness held or represented by each, for application to the payment of all obligations with respect to Senior Indebtedness remaining unpaid, to the extent necessary to pay or to provide for the payment
of all such obligations in full in cash or Cash Equivalents in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. 
  
 In the event that, notwithstanding the other provisions of this Article
Thirteen, a Holder receives any payment or distribution of any Obligations with respect to the Securities at a time when such payment or distribution is prohibited by Section 1303 hereof, such payment or distribution shall be paid forthwith over and
delivered, upon written request, to, the holders of Senior Indebtedness remaining unpaid or unprovided for or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments representing
any of such Senior Indebtedness may have been issued, ratably according to aggregate principal amounts remaining unpaid on account of such Senior Indebtedness held or represented by such, for application to the payment of all obligations with
respect to Senior Indebtedness remaining unpaid, to the extent necessary to pay or to provide for the payment of all such obligations in full in cash or Cash Equivalents in accordance with their terms, after giving effect to any concurrent payment
or distribution to or for the holders of Senior Indebtedness. 
  
 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article Thirteen, and no implied covenants or obligations with
respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company or any other Person money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article Thirteen, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee. 
  

 97 

 SECTION 1306. Notice by Company. The Company shall promptly notify the Trustee and the Paying
Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Securities to violate this Article Thirteen, but failure to give such notice shall not affect the subordination of the Securities to the Senior
Indebtedness as provided in this Article Thirteen. 
  
 SECTION
1307. Subrogation. After all Senior Indebtedness is paid in full in cash or Cash Equivalents and until the Securities are paid in full, Holders shall be subrogated (equally and ratably with all other Indebtedness pari passu with the
Securities) to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness to the extent that distributions otherwise payable to the Holders have been applied to the payment of Senior Indebtedness. A
distribution made under this Article Thirteen to holders of Senior Indebtedness that otherwise would have been made to Holders is not, as between the Company and Holders, a payment by the Company on the Securities. No holder of Senior Indebtedness
shall be obligated to create, warrant, preserve or protect any such subrogation right or shall suffer any loss or diminution of its rights hereunder if for any reason such right of subrogation is not available to any Holder. 
  
 SECTION 1308. Relative Rights. This Article defines the relative
rights of Holders and holders of Senior Indebtedness. Nothing in this Indenture shall: 
  
 (1) impair, as between the Company and Holders, the obligation of the Company, which is absolute and unconditional, to pay principal of
(and premium, if any) and interest (and Additional Interest, if any) on the Securities in accordance with their terms; 
  
 (2) affect the relative rights of Holders and creditors of the Company other than their rights in relation to holders of Senior
Indebtedness; or 
  
 (3) prevent the Trustee or
any Holder from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders of Senior Indebtedness to receive distributions and payments otherwise payable to Holders. 
  
 If the Company fails because of this Article to pay principal of (or premium,
if any) or interest (or Additional Interest, if any) on a Security on the due date, the failure is still a Default or Event of Default. 
  
 SECTION 1309. Subordination May Not be Impaired by Company. No right of any holder of Senior Indebtedness to enforce the subordination of the
Indebtedness evidenced by the Securities shall be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company or any holder of Senior Indebtedness to comply with this Indenture. 
  
 Without in any way limiting the generality of the foregoing paragraph, the
holders of the Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or Holders, without incurring responsibility to the 
  

 98 

 Holders and without impairing or releasing the subordination provided in this Article Thirteen or the obligations
hereunder of the Holders to the holders of Senior Indebtedness, do any one or more of the following: (a) change the manner, place or terms of payment or extend the time or payment of, or renew or alter, Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is outstanding; provided, however, that any such alteration shall not (i) increase the amount of Senior Indebtedness outstanding in a manner prohibited by this
Indenture or (ii) otherwise violate Section 1008 hereof; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (c) release any Person in any manner for the collection of Senior
Indebtedness; and (d) exercise or refrain from exercising any rights against the Company or any other Person; provided, however, that in no event shall any such actions limit the right of the Holders to take any action to accelerate
the maturity of the Securities in accordance with the provisions set forth in Section 502 or to pursue any rights or remedies against the parties to this Indenture under this Indenture or under applicable laws if the taking of such action does not
otherwise violate the terms of this Article Thirteen. 
  
 SECTION
1310. Rights of Trustee and Paying Agent. Notwithstanding the provisions of this Article Thirteen or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the
making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Securities, unless the Trustee shall have received at its Corporate Trust Office at least five Business Days prior to the
date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Securities to violate this Article Thirteen. Only the Company or the Representative may give the notice. Nothing in this Article
Thirteen shall impair the claims of, or payments to, the Trustee under or pursuant to Section 607 hereof. 
  
 The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. 
  
 SECTION 1311. Authorization to Effect Subordination. Each Holder of a
Security by the Holder’s acceptance thereof authorizes and directs the Trustee on the Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article Thirteen, and appoints
the Trustee to act as the Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of Indebtedness in the form required in any proceeding referred to in Section 504 hereof at least
30 days before the expiration of the time to file such claim, the Representative is hereby authorized to file an appropriate claim for and on behalf of the Holders. 
  
 SECTION 1312. Amendments. The provisions of this Article Thirteen or any related definitions shall not be amended or
modified in a manner adverse to the holders of Senior Indebtedness without the written consent of the holders of all Senior Indebtedness. 
  

 99 

 SECTION 1313. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other person
cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its
covenants or obligations as are specifically set forth in this Article and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee. 
  
 ARTICLE FOURTEEN 
  
 Subsidiary Guarantees 
  
 SECTION 1401. Subsidiary Guarantees. Subject to the provisions of
this Article Fourteen, each of the Company’s Domestic Restricted Subsidiaries (other than Permitted Joint Ventures and Receivables Entities), jointly and severally, hereby irrevocably and unconditionally fully guarantees to each Holder of a
Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns (the “Subsidiary Guarantee”), that: (a) the principal of, and premium, if any, and interest (and Additional Interest, if any) on the
Securities shall be duly and punctually paid in full when due, whether at maturity, by acceleration or otherwise, and interest on overdue principal, and premium, if any, and (to the extent permitted by law) interest on any interest and Additional
Interest, if any, on the Securities and all other obligations of the Company to the Holders or the Trustee hereunder or under the Securities (including fees, expenses or other) shall be promptly paid in full or performed, all in accordance with the
terms hereof; and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, the 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 failing performance of any other obligation of the Company to the Holders, for whatever reason, each Guarantor shall be obligated to
pay, or to perform or to cause the performance of, the same immediately. An Event of Default under this Indenture or the Securities shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Trustee or the Holders to
accelerate the obligations of each Guarantor hereunder in the same manner and to the same extent as the obligations of the Company. Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any thereof, the entry of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives and relinquishes: (a) any right to require the Trustee, the Holders or the Company (each, a
“Benefitted Party”) to proceed against the Company, the Subsidiaries or any other Person or to proceed against or exhaust any security held by a Benefitted Party at 
  

 100 

 any time or to pursue any other remedy in any secured party’s power before proceeding against the Subsidiaries; (b)
any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or Persons or the failure of a Benefitted Party to file or enforce a claim against the estate (in administration, bankruptcy or any
other proceeding) of any other Person or Persons; (c) demand, protest and notice of any kind (except as expressly required by this Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional
Indebtedness or obligation or of any action or non-action on the part of the Guarantors, the Company, the Subsidiaries, any Benefitted Party, any creditor of the Guarantors, the Company or the Subsidiaries or on the part of any other Person
whomsoever in connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Benefitted Party, including but not limited to an election to proceed against the Guarantors for
reimbursement; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any defense arising because of
a Benefitted Party’s election, in any proceeding instituted under the Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Code; and (g) any defense based on any borrowing or grant of a security interest under Section 364
of the Bankruptcy Code. The Guarantors hereby covenant that the Subsidiary Guarantees shall not be discharged except by payment in full of all principal, premium, if any, and interest on the Securities and all other costs provided for under this
Indenture, or except as provided in Sections 1202 and 1404. 
  
 If
any Holder or the Trustee is required by any court or otherwise to return to either the Company or the Guarantors, or any trustee or similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or the
Guarantors to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each of the Guarantors agrees that it shall not be entitled to any right of subrogation in
relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x)
the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Five hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purpose of its
Subsidiary Guarantee. 
  
 SECTION 1402. Execution and Delivery
of Subsidiary Guarantees. To evidence the Subsidiary Guarantees set forth in Section 1401 hereof, each of the Guarantors agrees that a Subsidiary Guarantee substantially in the form of Exhibit A hereto shall be endorsed on each Security
authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Guarantor by its Chairman of the Board, its President or one of its Vice Presidents. 
  

 101 

 Each of the Guarantors agrees that the Subsidiary Guarantees set forth in this Article Fourteen shall
remain in full force and effect and apply to all of the Securities notwithstanding any failure to endorse on each Security a notation of the Subsidiary Guarantees. 
  
 If an individual whose manual or facsimile signature is on a Security shall have ceased to hold such office prior to the
authentication and delivery of the Security on which the Subsidiary Guarantees are endorsed, the Subsidiary Guarantees shall be valid nevertheless. 
  
 The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantees
endorsed thereon and set forth in this Indenture and shall bind each Guarantor notwithstanding the fact that a Subsidiary Guarantee does not bear the signature of such Guarantor. Each of the Guarantors hereby jointly and severally agrees that its
form of Subsidiary Guarantee set forth in Section 1401 and in the form of Subsidiary Guarantee established pursuant to Exhibit A shall remain in full force and effect notwithstanding any failure to endorse a Subsidiary Guarantee on any Security.

  
 SECTION 1403. Guarantors May Consolidate, etc., on Certain
Terms. 
  
 (a) Nothing contained in this Indenture or in the
Securities shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent the transfer of all or substantially all of the assets of a Guarantor to the Company or another Guarantor. Upon any
such consolidation, merger, transfer or sale, the Subsidiary Guarantee of such Guarantor shall no longer have any force or effect. 
  
 (a) Except as provided in Section 1403(a), or a transaction referred to in Section 1404, no Guarantor shall consolidate with or merge with or into
(whether or not such Guarantor is the surviving corporation) another Person other than the Company or another Guarantor, whether in a single transaction or a series of related transactions, unless (i) subject to the provisions of Section 1404
hereof, the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor in connection with the Subsidiary Guarantees and this Indenture pursuant to a supplemental
indenture in a form reasonably satisfactory to the Trustee, pursuant to which such Person shall unconditionally guarantee on a senior subordinated basis all of such Guarantor’s obligations under such Guarantor’s Subsidiary Guarantee and
this Indenture on the terms set forth in this Indenture; (ii) immediately before and immediately after giving effect to such transaction on a pro forma basis, no Default or Event of Default shall have occurred and be continuing; and (iii)
such Guarantor shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel addressed to the Trustee, each stating that such consolidation or merger and such supplemental indenture, if any, comply with this Indenture
and that such supplemental indenture is enforceable. In case of any such consolidation or merger and upon the assumption by the successor corporation, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Subsidiary 
  

 102 

 Guarantees endorsed upon the Securities and the due and punctual performance of all of the covenants and conditions of
this Indenture to be performed by such Guarantor, such successor corporation shall succeed to and be substituted for such Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor corporation thereupon may cause to
be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Securities issuable hereunder which theretofore shall have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued shall in all
respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date
of the execution hereof. 
  
 (b) The Trustee, subject to the
provisions of Section 1404 hereof, shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale or conveyance, and any such assumption of obligations, comply
with the provisions of this Section 1403. 
  
 SECTION 1404.
Releases Following Sale of Assets. Upon the sale or disposition (whether by merger, stock purchase, asset sale or otherwise) of a Guarantor (or all or substantially all of the assets of any such Guarantor or 50% or more of the Equity
Interests of any such Guarantor) to an entity which is not a Guarantor or the designation of a Subsidiary to become an Unrestricted Subsidiary, which transaction is otherwise in compliance with this Indenture, including without limitation Section
1015 hereof, such Guarantor shall be deemed released from its obligations under its Subsidiary Guarantee. Upon delivery by the Company to the Trustee of an Officer’s Certificate and Opinion of Counsel, to the effect that such sale or other
disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 1015 hereof, the Trustee shall execute any documents reasonably required in order to evidence the release of any such
Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest on the Securities and for the other
obligations of any Guarantor under this Indenture as provided in this Article Fourteen. 
  
 SECTION 1405. Limitation of Guarantor’s Liability. Each Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such
Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To
effectuate the foregoing intention, the Holders and such Guarantor hereby irrevocably agree that the obligations of such Guarantor under this Article Fourteen shall be limited to the maximum amount as shall, after giving effect to all other
contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article Fourteen, result in
the obligations of such Guarantor under the Subsidiary Guarantee of such Guarantor not constituting a fraudulent transfer or conveyance. 
  

 103 

 SECTION 1406. Application of Certain Terms and Provisions to the Guarantors. (a) For purposes of
any provision of this Indenture which provides for the delivery by any Guarantor of an Officers’ Certificate and/or an Opinion of Counsel, the definitions of such terms in Section 101 shall apply to such Guarantor as if references therein to
the Company were references to such Guarantor. 
  
 (b) Any
request, demand, authorization, direction, notice, consent, waiver or other document which by any provision of this Indenture is to be made by any Guarantor, shall be sufficient if evidenced as described in Section 105 as if references therein to
the Company were references to such Guarantor. 
  
 (c) Any
request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document which by any provision of this Indenture is required or permitted to be given or served by the Trustee or by any Holder may be given or served as

 2.3 Transfer and Exchange 
  
 (a) Transfer and Exchange of Definitive Securities. When Definitive Securities are presented to the Notes Registrar with a request: 
  

	 	(x)	 	to register the transfer of such Definitive Securities; or 

  

	 	(y)	 	to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other authorized denominations, 

  
 the Notes Registrar shall register the transfer or make the exchange as requested if its
reasonable requirements for such transaction are met; provided, however, that the Definitive Securities surrendered for transfer or exchange: 
  
 (i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Notes
Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 
  
 (ii) if such Definitive Securities are required to bear a restricted securities legend, are being transferred or exchanged pursuant to an
effective registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable: 
  
 (A) if such Definitive Securities are being delivered to the
Notes Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or 
  
 (B) if such Definitive Securities are being transferred to the Company, a certification to that effect; or 
  
 (C) if such Definitive Securities are being transferred (x)
pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act: (i) a certification to that effect (in
the form set forth on the reverse of the Security) and (ii) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section
2.3(e)(i). 
  
 (b) Restrictions on Transfer of a Definitive
Security for a Beneficial Interest in a Global Security. A Definitive Security may not be exchanged for a beneficial interest in a Rule 144A Global Security, an IAI Global Security or a Permanent Regulation S Global Security except upon
satisfaction of the requirements set forth 

  

 6 

 
below. Upon receipt by the Trustee of a Definitive Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the
Trustee, together with: 
  
 (i) certification, in
the form set forth on the reverse of the Security, that such Definitive Security is either (A) being transferred to a QIB in accordance with Rule 144A, (B) being transferred to an IAI or (C) being transferred after expiration of the Distribution
Compliance Period by a Person who initially purchased such Security in reliance on Regulation S to a purchaser who elects to hold its interest in such Security in the form of a beneficial interest in the Permanent Regulation S Global Security; and

  
 (ii) written instructions directing the
Trustee to make, or to direct the Securities Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause (b)(i)(A)), IAI Global Security (in the case of a
transfer pursuant to clause (b)(1)(B)) or Permanent Regulation S Global Security (in the case of a transfer pursuant to clause (b)(i)(C)) to reflect an increase in the aggregate principal amount of the Securities represented by the Rule 144A Global
Security, IAI Global Security or Permanent Regulation S Global Security, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase, 
  
 then the Trustee shall cancel such Definitive Security and cause, or direct the Securities
Custodian to cause, in accordance with the standing instructions and procedures existing between the Depository and the Securities Custodian, the aggregate principal amount of Securities represented by the Rule 144A Global Security, IAI Global
Security or Permanent Regulation S Global Security, as applicable, to be increased by the aggregate principal amount of the Definitive Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such
instructions a beneficial interest in the Rule 144A Global Security, IAI Global Security or Permanent Regulation S Global Security, as applicable, equal to the principal amount of the Definitive Security so canceled. If no Rule 144A Global
Securities, IAI Global Securities or Permanent Regulation S Global Securities, as applicable, are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’
Certificate of the Company, a new Rule 144A Global Security, IAI Global Security or Permanent Regulation S Global Security, as applicable, in the appropriate principal amount. 
  
 (c) Transfer and Exchange of Global Securities. 
  
 (i) The transfer and exchange of Global Securities or beneficial interests therein shall be effected through
the Depository, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Security shall deliver to the
Notes Registrar a written order given in accordance with the Depository’s procedures containing information regarding 

  

 7 

 
the participant account of the Depository to be credited with a beneficial interest in the Global Security. The Notes Registrar shall, in accordance with
such instructions, instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global Security and to debit the account of the Person making the transfer the beneficial interest in the
Global Security being transferred. 
  
 (ii) If
the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the
Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the
principal amount of the Global Security from which such interest is being transferred. 
  
 (iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Security may
not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a
nominee of such successor Depository. 
  
 (iv) In
the event that a Global Security is exchanged for Definitive Securities pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such
Securities, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Securities
intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company. 
  
 (d) Restrictions on Transfer of Temporary Regulation S Global
Securities. During the Distribution Compliance Period, beneficial ownership interests in Temporary Regulation S Global Securities may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (i) to the Company,
(ii) in an offshore transaction in accordance with Regulation S (other than a transaction resulting in an exchange for an interest in a Permanent Regulation S Global Security), (iii) pursuant to an effective registration statement under the
Securities Act, in each case in accordance with any applicable securities laws of any State of the United States. 
  
 (e) Legend. 
  
 (i) Except as permitted by the following paragraphs (ii), (iii) and (iv), each Security certificate evidencing the Global Securities (and
all Securities 

  

 8 

 
issued in exchange therefor or in substitution thereof), in the case of Securities offered otherwise than in reliance on Regulation S, shall bear a legend in
substantially the following form: 
  
 THIS SECURITY (OR ITS
PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE
ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY
RULE 144A THEREUNDER. 
  
 THE HOLDER OF THIS SECURITY AGREES FOR
THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO THE COMPANY, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS
DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) TO AN “ACCREDITED INVESTOR” WITHIN THE MEANING OF RULE 501(A)(1),(2),(3) OR (7) UNDER THE SECURITIES ACT THAT IS AN INSTITUTIONAL
INVESTOR ACQUIRING THE SECURITIES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF SUCH AN INSTITUTIONAL ACCREDITED INVESTOR, IN EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF THE SECURITIES OF $250,000, FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO OR FOR
OFFER OR SALE IN CONNECTION WITH ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, (IV) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (V) PURSUANT TO EXEMPTION FROM REGISTRATION UNDER

 9 

 Each certificate evidencing a Security offered in reliance on Regulation S shall, in
addition to the foregoing, bear a legend in substantially the following form: 
  
 THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE
TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE
HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT. 
  
 Each Definitive Security shall also bear the following additional legend: 
  
 IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER
AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS. 
  
 (ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global
Security) pursuant to Rule 144 under the Securities Act, the Notes Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any
restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the
reverse of the Security). 
  
 (iii) After a
transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Private Exchange Securities, as the case may be,
all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Private Exchange Security issued to certain Holders be issued in
global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case without restrictive transfer legends, will be available to the
transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such 

  

 10 

 
transferring Holder’s certificated Initial Security or Private Exchange Security or directions to transfer such Holder’s interest in the Global
Security, as applicable. 
  
 (iv) Upon the
consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to
Holders of such Initial Securities that do not exchange their Initial Securities, and Exchange Securities in certificated or global form, in each case without the restricted securities legend set forth in Exhibit 1 hereto will be available to
Holders that exchange such Initial Securities in such Registered Exchange Offer. 
  
 (v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such Initial
Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange Securities in global form
with the global securities legend and the applicable restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange. 
  
 (f) Cancellation or Adjustment of Global Security. At such time as all
beneficial interests in a Global Security have either been exchanged for Definitive Securities, redeemed, purchased or canceled, such Global Security shall be retained and canceled by the Trustee. At any time prior to such cancellation, if any
beneficial interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books
and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction. 
  
 (g) No Obligation of the Trustee. 
  
 (i) The Trustee shall have no responsibility or obligation to
any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any
ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or
with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the
Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely
and shall be fully protected in relying upon information 

  

 11 

 
furnished by the Depository with respect to its members, participants and any beneficial owners. 
  
 (ii) The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository
participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of
this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
  
 2.4 Certificated Securities 
  
 (a) A Global Security deposited with the Depository or with the Trustee as Securities Custodian for the Depository pursuant to Section 2.1 shall be
transferred to the beneficial owners thereof in the form of Definitive Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such transfer complies with
Section 2.3 hereof and (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security and the Depository fails to appoint a successor depositary or if at any time such Depository ceases to

and delivered only in denominations of $1,000 principal amount and any integral multiple thereof and registered in such names as the Depository shall direct. Any Definitive Security delivered in exchange for an interest in the Transfer Restricted
Security shall, except as otherwise provided by Section 2.3(e) hereof, bear the applicable restricted securities legend and definitive note legend set forth in Exhibit 1 hereto. 
  
 (c) Subject to the provisions of Section 2.4(b) hereof, the registered Holder of a Global Security shall be entitled to
grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 
  

 12 

 (d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Company
shall promptly make available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons.

 [FORM OF REVERSE SIDE OF INITIAL SECURITY] 
  
 9 1/2% Senior Subordinated Note Due 2010 
  

	1.	 	Interest 

  
 Concentra Operating Corporation, a Nevada corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being
herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights
Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum for the first 90-day period immediately following the occurrence of a Registration Default (increasing by an additional 0.25% per annum with respect to
each subsequent 90-day period up to a maximum additional interest rate of 2.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. The Company
will pay interest semiannually on February 15 and August 15 of each year, commencing February 15, 2004. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from August
13, 2003. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Security, and it will pay interest on overdue installments of interest at the
same rate to the extent lawful. 
  

	2.	 	Method of Payment 

  
 The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of
business on the February 1 or August 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security
(including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company will make all payments in respect of a certificated Security (including principal,
premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with
a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion). 

	3.	 	Paying Agent and Notes Registrar 

  
 Initially, The Bank of New York, a New York banking corporation (the “Trustee”), will act as Paying Agent and Notes Registrar. The Company may
appoint and change any Paying Agent, Notes Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Notes Registrar or co-registrar. 
  

	4.	 	Indenture 

  
 The Company issued the Securities under an Indenture dated as of August 13, 2003 (the “Indenture”), among the Company, the Guarantors and the
Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture
(the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of
those terms. 
  
 The Securities are general unsecured obligations
of the Company. The Company shall be entitled, subject to its compliance with Section 1008 of the Indenture, to issue Additional Securities pursuant to Section 301 and Section 901(6) of the Indenture. The Initial Securities issued on the Issue Date,

Company and its subsidiaries to incur or guarantee additional indebtedness and issue certain preferred stock; pay dividends or make distributions to its stockholders; repurchase or redeem capital stock or subordinated indebtedness; make investments;
create liens; issue or sell capital stock of subsidiaries; engage in transactions with affiliates; transfer or sell assets; restrict dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially all of its assets
and the assets of its subsidiaries. These covenants are subject to important exceptions and qualifications.

 On or after August 15, 2007, the Company shall be entitled at its option to redeem all or a portion of
the Securities (including Additional Securities, if any) upon not less than 30 nor more than 60 days’ notice, at the Redemption Prices (expressed in percentages of principal amount on the Redemption Date) plus accrued and unpaid interest
thereon to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month period commencing on August 15 of the years set

	 2009 and thereafter
	  	100.000	%

  
 In addition, prior to
August 15, 2006, the Company shall be entitled at its option on one or more occasions to redeem Securities (including Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the
Securities (which includes Additional Securities, if any) originally issued under the Indenture at a Redemption Price (expressed as a percentage of principal amount) of 109.500%, plus accrued and unpaid interest to the Redemption Date, with the net
cash proceeds from one or more Equity Offerings; provided, however, that (1) at least 65% of such aggregate principal amount of Securities (which includes Additional Securities, if any) remains outstanding immediately after the
occurrence of each such redemption (excluding Securities held by the Company or its Subsidiaries); and (2) each such redemption occurs within 90 days of the date of the closing of the related Equity Offering. 
  
 Prior to August 15, 2007 the Company may at its option redeem all, but not
less than all, of the Securities (including Additional Securities, if any) at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and accrued and unpaid interest to, the Redemption Date
(subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date). Notice of such redemption must be mailed by first-class mail to each Holder’s registered address, not less than 30 or
more than 60 days prior to the Redemption Date. 
  

	6.	 	Notice of Redemption 

  
 Notice of redemption will be mailed by first-class mail, postage prepaid, at least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the Redemption Price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent on or before the Redemption Date and certain other conditions are 

 
satisfied, on and after such date interest shall cease to accrue on such Securities (or such portions thereof) called for redemption. 
  

	7.	 	Put Provisions 

  
 Upon a Change of Control, any Holder of Securities will have the right to cause the Company to repurchase all or any part of the Securities of such Holder
at a repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the
related Interest Payment Date) as provided in, and subject to the terms of, the Indenture.

 The payment by the Company of the principal of, and premium and interest on, the Securities is fully and unconditionally guaranteed on a joint and several
senior subordinated basis by each of the Guarantors to the extent set forth in the Indenture. 
  

	9.	 	Subordination 

  
 The Securities are subordinated to Senior Indebtedness of the Company and the Guarantors on the terms and subject to the conditions set forth in the
Indenture. To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid. Each Holder by accepting a Security agrees to the subordination provisions contained in the Indenture and authorizes the Trustee
to give effect to such provisions and appoints the Trustee as attorney-in-fact for such purpose. 
  

	10.	 	Denominations; Transfer; Exchange 

  
 The Securities are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Notes Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Notes Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a
period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 
  

	11.	 	Persons Deemed Owners 

  
 The registered Holder of this Security may be treated as the owner of it for all purposes. 

	12.	 	Unclaimed Money 

  
 If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at
its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 
  

	13.	 	Discharge and Defeasance 

  
 Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 
  

	14.	 	Amendment, Waiver 

  
 Subject to certain exceptions set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of the Holders of
at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company, the Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Securities in addition to or in place of certificated Securities, to provide for the assumption of the Company’s obligations to Holders in the case of a merger or consolidation or the sale of all or substantially all
of the Company’s assets, to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect in any material respect the legal rights under the Indenture of any such Holder, to comply with
the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Act, to provide for the issuance of Additional Securities in accordance with the limitations set forth in the Indenture or to allow any
Subsidiary to guarantee the Securities. 
  

	15.	 	Defaults and Remedies 

  
 Under the Indenture, Events of Default include (a) default for 30 days in payment of interest on the Securities, whether or not prohibited by the
subordination provisions of the Indenture; (b) default in payment of principal or premium, if any on the Securities, whether or not prohibited by the subordination provisions of the Indenture; (c) failure by the Company to comply with a covenant
providing for certain limitations on mergers, consolidations or sales of assets; (d) failure by the Company, subject to certain notice, to comply with the covenants providing for repurchases at the option of holders upon a Change of Control and upon
certain asset sales, limitations on Restricted Payments or limitations on incurrence of certain indebtedness; (e) failure by the 

 
Company or any Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (f)
certain accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds $20.0 million; (g) certain events of bankruptcy or insolvency with
respect to the Company and the Company’s Significant Subsidiaries; (h) certain judgments or decrees for the payment of money in excess of $20.0 million; and (i) certain defaults with respect to Subsidiary Guarantees. If an Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will
result in the Securities being due and payable immediately upon the occurrence of such Events of Default. 
  
 Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the
Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 
  

	16.	 	Trustee Dealings with the Company 

  
 Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	17.	 	No Recourse Against Others 

  
 A director, officer, employee, incorporator or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the
Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Securities. 
  

	18.	 	Authentication 

  
 This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security. 
  

	19.	 	Abbreviations 

  
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the 

 
entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

  

	20.	 	CUSIP Numbers 

  
 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed
on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice
of redemption and reliance may be placed only on the other identification numbers placed thereon. 
  

	21.	 	Holders’ Compliance with Registration Rights Agreement 

  
 Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations
of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.

 9 1/2% Senior Subordinated Note Due 2010 
  

	1.	 	Interest 

  
 Concentra Operating Corporation, a Nevada corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being
herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; [provided, however, that if a Registration Default (as defined in the Registration Rights
Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum for the first 90-day period immediately following the occurrence of Registration Default (increasing by an additional 0.25% per annum after with respect
to each subsequent 90-day period up to a maximum additional interest rate of 2.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been
cured.]1 The Company will pay interest semiannually on February 15 and August 15 of each year, commencing February
15, 2004. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from August 13, 2003. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The
Company will pay interest on overdue principal at the rate borne by this Security, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	 	Method of Payment 

  
 The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of
business on the February 1 or August 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security
(including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company will make all payments in respect of a certificated Security (including principal,
premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with
a bank in 

 1 Insert if at the date of issuance of the Exchange Security or the Private Exchange Security (as the case may be) any Registration Default has occurred with
respect to the related Initial Securities during the interest period in which the date of issuance occurs. 

 
the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such
account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
  

	3.	 	Paying Agent and Notes Registrar 

  
 Initially, The Bank of New York, a New York banking corporation (the “Trustee”), will act as Paying Agent and Notes Registrar. The Company may
appoint and change any Paying Agent, Notes Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Notes Registrar or co-registrar. 
  

	4.	 	Indenture 

  
 The Company issued the Securities under an Indenture dated as of August 13, 2003 (the “Indenture”), among the Company, the Guarantors and the
Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture
(the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of
those terms. 
  
 The Securities are general unsecured obligations
of the Company. The Company shall be entitled, subject to its compliance with Section 1008 of the Indenture, to issue Additional Securities pursuant to Section 301 and Section 901(6) of the Indenture. The Initial Securities issued on the Issue Date,
any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the
Company and its subsidiaries to incur additional indebtedness and issue certain preferred stock; pay dividends or make distributions to its stockholders; repurchase or redeem capital stock or subordinated indebtedness; make investments; create
liens; issue or sell capital stock of subsidiaries; engage in transactions with affiliates; transfer or sell assets; restrict dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially all of its assets and the
assets of its subsidiaries. These covenants are subject to important exceptions and qualifications. 
  

	5.	 	Optional Redemption 

  
 Except as set forth below, the Company shall not be entitled to redeem the Securities. 
  
 On or after August 15, 2007, the Company shall be entitled at its option to redeem all or a portion of the Securities
(including Additional Securities, if any) upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the Redemption Date) plus accrued and unpaid interest to the Redemption
Date (subject to the right of Holders of record on the relevant record date to 

 
receive interest due on the relevant Interest Payment Date),if redeemed during the 12-month period commencing on August 15 of the years set forth below:

  

	 Period

	  	 Redemption

	 2007

	 2008
	  	102.375	%
	 2009 and thereafter
	  	100.000	%

  
 In addition, prior to
August 15, 2006, the Company shall be entitled at its option on one or more occasions to redeem Securities (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the
Securities (which includes Additional Securities, if any) originally issued under the Indenture at a Redemption Price (expressed as a percentage of principal amount) of 109.500%, plus accrued and unpaid interest to the Redemption Date, with the net
cash proceeds from one or more Equity Offerings; provided, however, that (1) at least 65% of such aggregate principal amount of Securities (which includes Additional Securities, if any) remains outstanding immediately after the
occurrence of each such redemption (excluding Securities held by the Company or its Subsidiaries); and (2) each such redemption occurs within 90 days of the date of the closing of the related Equity Offering. 
  
 Prior to August 15, 2007 the Company may at its option redeem all, but not
less than all, of the Securities (including Additional Securities, if any) at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and accrued and unpaid interest to, the Redemption Date
(subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date). Notice of such redemption must be mailed by first-class mail to each Holder’s registered address, not less than 30 or
more than 60 days prior to the Redemption Date. 
  

	6.	 	Notice of Redemption 

  
 Notice of redemption will be mailed by first-class mail, postage prepaid, at least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the Redemption Price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent on or before the Redemption Date and certain other conditions are satisfied, on and after such date interest shall
cease to accrue on such Securities (or such portions thereof) called for redemption. 

	7.	 	Put Provisions 

  
 Upon a Change of Control, any Holder of Securities will have the right to cause the Company to repurchase all or any part of the Securities of such Holder
at a repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the
related Interest Payment Date) as provided in, and subject to the terms of, the Indenture. 
  

	8.	 	Guaranty 

  
 The payment by the Company of the principal of, and premium and interest on, the Securities is fully and unconditionally guaranteed on a joint and several
senior subordinated basis by each of the Guarantors to the extent set forth in the Indenture. 
  

	9.	 	Subordination 

  
 The Securities are subordinated to Senior Indebtedness of the Company and the Guarantors on the terms and subject to the conditions set forth in the
Indenture. To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid. Each Holder by accepting a Security agrees to the subordination provisions contained in the Indenture and authorizes the Trustee
to give effect to such provision and appoints the Trustee as attorney-in-fact for such purpose. 
  

	10.	 	Denominations; Transfer; Exchange 

  
 The Securities are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Notes Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Notes Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a
period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date. 
  

	11.	 	Persons Deemed Owners 

  
 The registered Holder of this Security may be treated as the owner of it for all purposes. 
  

	12.	 	Unclaimed Money 

  
 If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at
its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment. 

	13.	 	Discharge and Defeasance 

  
 Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 
  

	14.	 	Amendment; Waiver 

  
 Subject to certain exceptions set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of the Holders of
at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company, the Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Securities in addition to or in place of certificated Securities, to provide for the assumption of the Company’s obligations to Holders in the case of a merger or consolidation or the sale of all or substantially all
of the Company’s assets, to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect in any material respect the legal rights under the Indenture of any such Holder, to comply with
the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Act, to provide for the issuance of Additional Securities in accordance with the limitations set forth in the Indenture or to allow any
Subsidiary to guarantee the Securities. 
  

	15.	 	Defaults and Remedies 

  
 Under the Indenture, Events of Default include (a) default for 30 days in payment of interest on the Securities, whether or not prohibited by the
subordination provisions of the Indenture; (b) default in payment of principal on the Securities, (c) failure by the Company or any Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and
lapse of time; (c) failure by the Company to comply with a covenant providing for certain limitations on mergers, consolidations or sales of assets; (d) failure by the Company, subject to certain notice, to comply with the covenants providing for
repurchase at the option of holders upon a Change of Control and upon certain asset sales, limitations on Restricted Payments or limitations on incurrence of certain indebtedness; (e) certain accelerations (including failure to pay within any grace
period after final maturity) of other Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds $20.0 million; (f) certain events of bankruptcy or insolvency with respect to the Company and the Company’s Significant
Subsidiaries; (g) certain judgments or decrees for the payment of money in excess of $20.0 million; and (h) certain defaults with respect to Subsidiary Guarantees. If an Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. 

 
Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of
such Events of Default. 
  
 Holders may not enforce the Indenture
or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal
amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding
notice is in the interest of the Holders. 
  

	16.	 	Trustee Dealings with the Company 

  
 Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	17.	 	No Recourse Against Others 

  
 A director, officer, employee, incorporator or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the
Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Securities. 
  

	18.	 	Authentication 

  
 This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security. 
  

	19.	 	Abbreviations 

  
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT
TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 
  

	20.	 	CUSIP Numbers 

  
 Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed
on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of 

 
such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification
numbers placed thereon. 
  

	21.	 	Holders’ Compliance with Registration Rights Agreement 

  
 Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations
of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.

 The undersigned represents

 1. We are an institutional

“accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such
knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to the Securities in the normal course of our
business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment. 
  
 2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is two years after the later of the date of
original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (i) to the 

 
Company, (ii) in the United States to a person whom the seller reasonably believes is a qualified institutional buyer in a transaction meeting the
requirements of Rule 144A, (iii) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is an institutional accredited investor purchasing for its own account or for
the account of an institutional accredited investor, in each case in a minimum principal amount of the Securities of $250,000, (iv) outside the United States in a transaction complying with the provisions of Rule 904 under the Securities Act, (v)
pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if available) or (vi) pursuant to an effective registration statement under the Securities Act, in each of cases (i) through (vi) subject to any requirement of
law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (iii) above prior to the Resale Restriction Termination Date, the transferor shall deliver a
letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve
the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to clause (iii), (iv) or (v) above to require the delivery of an opinion of counsel certifications or other information
satisfactory to the Company and the Trustee.

 TO 9 1/2% SENIOR SUBORDINATED NOTES DUE 2010]

  
 For value received, each of the Guarantors listed
below (which term includes any successors or assigns under the Indenture, dated as of August 13, 2003 (the “Indenture”), among the Company, the Guarantors listed below and The Bank of New York, as Trustee, and any additional Guarantors
that become such following the date hereof), jointly and severally, fully and unconditionally, irrevocably, guarantees, as principal obligor and not only as surety, to the Holder of the Security on which this Subsidiary Guarantee is endorsed, and to
the Trustee on behalf of such Holders, (i) the due and punctual payment of the principal of, premium, if any, and interest (and Additional Interest, if any) on the Securities, whether at Stated Maturity, by acceleration or otherwise, the due and
punctual payment of interest on the overdue principal, and premium if any, and (to the extent permitted by law) interest on any interest and Additional Interest, if any, on the Securities, and the due and punctual performance of all other
obligations of the Company, all in accordance with the terms set forth in Article Fourteen of the Indenture, (ii) in case of any extension of time of payment or renewal of any Securities or any such other obligations, that the 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, and (iii) the payment of any and all costs and expenses (including reasonable attorneys’
fees) incurred by the Trustee or any Holder in enforcing any rights under this Subsidiary Guarantee. 
  
 The obligations of each Guarantor to the Holder and to the Trustee pursuant to this Subsidiary Guarantee and the Indenture are expressly set forth in
Article Fourteen of the Indenture and reference is hereby made to such Indenture for the precise terms of this Subsidiary Guarantee and other matters in respect of this Subsidiary Guarantee. 
  
 No reference herein to the Indenture and no provision of this Security or of
the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest and Additional Interest, if any, on this Security at the times, place and rate, and in
the coin or currency, herein prescribed. 
  
 Until the Indenture
is discharged and all of the Securities are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Company that arise from the
existence, payment, performance or enforcement of the Company’s obligations under the Securities or the Indenture and each Guarantor’s obligations under this Subsidiary Guarantee and this Indenture, in any such instance including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders and the Trustees against the Company, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or 

 
by set-off or in any other manner, payment or security on account of such claim or other rights. 
  
 No stockholder, officer, director, employee or incorporator, as such, past,
present or future of each Guarantor shall have any liability by reason of his or its status as such stockholder, officer, director, employee or incorporator for any obligations of any Guarantor under the Securities, the Indenture or its Subsidiary
Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. 
  
 This is a continuing guarantee and shall remain in full force and effect and shall be binding upon each Guarantor and its successors and assigns until
full and final payment of all of the Company’s obligations under the Securities and Indenture and shall inure to the benefit of the successors and assigns of the Trustee and the Holders, and, in the event of any transfer or assignment of rights
by any Holder or the Trustee, the rights and privileges herein conferred upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof and the Indenture. This is a
guarantee of payment and not of collectibility. 
  
 The
obligations of each Guarantor under its Subsidiary Guarantee shall be limited to the extent necessary to insure that it does not constitute a fraudulent transfer or conveyance under applicable law. 
  
 By delivery of a supplemental indenture to the Trustee in accordance with the
terms of the Indenture, each Person that becomes a Guarantor after the date of the Indenture will be deemed to have executed and delivered this Subsidiary Guarantee for the benefit of the Holder of the Note upon which this Subsidiary Guarantee is
endorsed with the same effect as if such Guarantor was named below and has executed and delivered this Subsidiary Guarantee. 
  
 All terms used in this Subsidiary Guarantee which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
  
 THIS SUBSIDIARY GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK. 
  
 (The remainder of this
page is blank) 

 IN WITNESS WHEREOF, each of the Guarantors has caused this Subsidiary Guarantee to be duly executed.

 Dear Sirs: 
  
 Concentra Operating Corporation, a Nevada corporation (the
“Issuer”), proposes to issue and sell to Credit Suisse First Boston LLC, Citigroup Global Markets Inc., Deutsche Bank Securities, Inc., J. P. Morgan Securities Inc. and Banc One Capital Markets, Inc. (collectively, the “Initial
Purchasers”), upon the terms set forth in a purchase agreement of even date herewith (the “Purchase Agreement”), $150,000,000 aggregate principal amount of its 9 1/2% Senior Subordinated Notes due 2010 (the “Initial Securities”) to be unconditionally guaranteed by each of the Subsidiaries listed on Schedule B to the Purchase
Agreement (the “Guarantors and, together with the Issuer, the “Company”). The Initial Securities will be issued pursuant to an Indenture, dated as of August 13 , 2003, (the “Indenture”) among the Company, the Guarantors and
The Bank of New York (the “Trustee”). As an inducement to the Initial Purchasers, the Company agrees with the Initial Purchasers, for the benefit of the holders of the Initial Securities (including, without limitation, the Initial
Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively the “Holders”), as follows: 
  
 1. Registered Exchange Offer. The Company shall, at its own cost, prepare and, not later than 90 days after (or if
the 90th day is not a business day, the first business day thereafter) the date of original issue of the Initial Securities (the “Issue Date”), file with the Securities and Exchange Commission (the “Commission”) a registration
statement (the “Exchange Offer Registration Statement”) on an appropriate form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer (the “Registered Exchange Offer”) to
the Holders of Transfer Restricted Securities (as defined in Section 6 hereof), who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for
the Initial Securities, a like aggregate principal amount of debt securities (the “Exchange Securities”) of the Company issued under the Indenture and identical in all material respects to the Initial Securities (except for the transfer
restrictions relating to the Initial Securities and the provisions relating to the matters described in Section 6 hereof) that would be registered under the Securities Act. The Company shall use its reasonable best efforts to cause such Exchange
Offer Registration Statement to become effective under the Securities Act within 180 days (or if the 180th day is not a business day, the first business day thereafter) after the Issue Date of the Initial Securities and shall keep the Exchange Offer
Registration Statement effective for not less than 30 days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such period being called the “Exchange Offer Registration
Period”). 

 If the Company effects the Registered Exchange Offer, the Company will be entitled to close the
Registered Exchange Offer 40 days after the commencement thereof provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer. 
  
 Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as defined in Section 6 hereof) electing to
exchange the Initial Securities for Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business
and has no arrangements with any person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities
from and after their receipt without any limitations or restrictions under the Securities Act and without material restrictions under the securities laws of the several states of the United States. 
  
 The Company acknowledges that, pursuant to current interpretations by the
Commission’s staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom, (i) each Holder which is a broker-dealer electing to exchange Securities, acquired for its own account as a result of market making
activities or other trading activities, for Exchange Securities (an “Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange
Offer Procedures” section and the “Purpose of the Exchange Offer” section, and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities received by
such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell Exchange Securities acquired in exchange for Initial Securities constituting any portion of an unsold allotment is required to deliver
a prospectus containing the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale. 
  
 The Company shall use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus
contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order
to resell the Exchange Securities; provided, however, that (i) in the case where such prospectus and any amendment or supplement thereto must be delivered by an Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of 180 days
and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment
or supplement thereto, available to any broker-dealer for use in connection with any resale of any Exchange Securities for a period of not less than 90 days after the consummation of the Registered Exchange Offer. 
  
 If, upon consummation of the Registered Exchange Offer, any Initial Purchaser
holds Initial Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon
the written request of such Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held by such Initial Purchaser, a like principal amount of debt securities of the Company issued under the Indenture and
identical in all material respects (including the existence of restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding provisions relating to the matters described in
Section 6 hereof) to the Initial Securities (the “Private Exchange Securities”). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the “Securities”. 
  
 In connection with the Registered Exchange Offer, the Company shall:

  

 2 

 (a) mail to each Holder a copy of the prospectus forming part of the Exchange Offer
Registration Statement, together with an appropriate letter of transmittal and related documents; 
  
 (b) keep the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice
thereof is mailed to the Holders; 
  
 (c) utilize
the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee; 
  
 (d) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York
time, on the last business day on which the Registered Exchange Offer shall remain open; and 
  
 (e) otherwise comply with all applicable laws. 
  
 As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall: 
  
 (x) accept for exchange all the Securities validly tendered
and not withdrawn pursuant to the Registered Exchange Offer and the Private Exchange; 
  
 (y) deliver to the Trustee for cancellation all the Initial Securities so accepted for exchange; and 
  
 (z) cause the Trustee to authenticate and deliver promptly
to each Holder of the Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for exchange. 
  
 The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one
another on any matter. 
  
 Interest on each Exchange Security and
Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if no
interest has been paid on the Initial Securities, from the date of original issue of the Initial Securities. 
  
 Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any person to participate in the distribution of the
Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will comply with
the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange
Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making activities or other trading activities and that it
will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. 
  
 Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any supplement thereto comply in all material respects with the Securities Act and the rules and regulations 

  

 3 

 
thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto do not, when they become effective, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any prospectus forming part of any Exchange Offer Registration Statement, and any supplement to such
prospectus, do not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading. 
  
 2. Shelf Registration. If, (i) because of
any change in law or in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not consummated
within 220 days of the Issue Date, (iii) any Initial Purchaser shall notify the Company following consummation of the Registered Exchange Offer that the Initial Securities (or the Private Exchange Securities) held by it are not eligible to be
exchanged for Exchange Securities in the Registered Exchange Offer; or (iv) any Holder (other than an Exchanging Dealer) notifies the Company in writing that it is prohibited by law or SEC policy from participating in the Registered Exchange Offer
or may not resell the Exchange Notes acquired by it in the Registered Exchange Offer to the public without delivering a prospectus, and the prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such
resales by it, the Company shall take the following actions: 
  
 (a) The Company shall, at its cost, as promptly as practicable (but in no event more than 60 days after so required or requested pursuant to this Section 2) file with the Commission a registration statement (the
“Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted
Securities (as defined in Section 6 hereof) by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf
Registration”); provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the
provisions of this Agreement applicable to such Holder. 
  
 (b) The Company shall (x) in the case of clause (i) above, use its reasonable best efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act on or prior to the 180th day after
the Issue Date and (y) in the case of clause (ii), (iii) or (iv) above, use its reasonable best efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act on or prior to the 60th day after the date on which
the Shelf Registration Statement is required to be filed. 
  
 (c) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the
relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the date of its effectiveness or such shorter period that will terminate when all the Securities covered by the Shelf
Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted securities (as defined in Rule 144 under the Securities Act, or any successor rule thereof). The Company shall be deemed not to have used its reasonable best
efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period,
unless such action is required by applicable law. 
  
 (d) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf
Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities 

  

 4 

 
Act and the rules and regulations thereunder and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. 
  
 3. Registration Procedures. In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent applicable, any
Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 
  
 (a) The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration
Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the
Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose;
(ii) include the information set forth in Annex A hereto on the cover, in Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section and in Annex C hereto in the “Plan of
Distribution” section of the prospectus forming a part of the Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer; (iii)
if requested by an Initial Purchaser within a reasonable time after receipt of any such document, include the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in the prospectus forming a part of the
Exchange Offer Registration Statement; (iv) include within the prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchasers, which shall
contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential “underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a “Participating Broker-Dealer”), whether such positions or policies have
been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing views of the staff
of the Commission; and (v) in the case of a Shelf Registration Statement, include the names of the Holders, who propose to sell Securities pursuant to the Shelf Registration Statement, as selling securityholders; provided, however, that each such
Holder shall have furnished to the Company on a timely basis such information regarding the Holder as the Company may require pursuant to Section 3(n) hereof. 
  

(b) The Company shall give written notice to the Initial Purchasers, the Holders of the Securities proposed to be sold under the Shelf
Registration Statement and any Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall
be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made): 
  
 (i) when the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration Statement or any
post-effective amendment thereto has become effective; 
  
 (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information; 
  

 5 

 (iii) of the issuance by the Commission of any stop order suspending the effectiveness of
the Registration Statement or the initiation of any proceedings for that purpose; 
  
 (iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the
Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 
  
 (v) of the happening of any event that requires the Company to make changes in the Registration Statement or the prospectus in order that
the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light
of the circumstances under which they were made) not misleading. 
  
 (c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the Registration Statement. 
  
 (d) The Company shall furnish to each Holder of Securities
included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Holder so requests in
writing, all exhibits thereto (including those, if any, incorporated by reference). 
  
 (e) The Company shall deliver to each Exchanging Dealer and each Initial Purchaser, and to any other Holder who so requests, without
charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if any Initial Purchaser or any such Holder requests, all exhibits thereto (including
those incorporated by reference). 
  
 (f) The
Company shall, during the Shelf Registration Period, deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in
the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by
each of the selling Holders of the Securities in connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 
  
 (g) The Company shall deliver to each Initial Purchaser, any
Exchanging Dealer, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration
Statement and any amendment or supplement thereto as such persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Initial
Purchaser, if necessary, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus,
or any amendment or supplement thereto, included in such Exchange Offer Registration Statement. 
  
 (h) Prior to any public offering of the Securities, pursuant to any Registration Statement, the Company shall register or qualify or
cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue sky” laws of such states of
the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts 

  

 6 

 
or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided,
however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any
jurisdiction where it is not then so subject. 
  
 (i) The Company shall cooperate with the Holders of the Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any Registration Statement free of any restrictive
legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement. 
  
 (j) Upon the occurrence of any event contemplated by
paragraphs (ii) through (v) of Section 3(b) above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration
Statement or a supplement to the related prospectus and any other required document so that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchasers, the Holders of the
Securities and any known Participating Broker-Dealer in accordance with paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers,
the Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration
Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders of the Securities and any known
Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j) or the Company shall have notified such Holders that disposition of such Transfer Restricted Securities may resume under the
existing prospectus. 
  
 (k) Not later than the
effective date of the applicable Registration Statement, the Company will provide a CUSIP number for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable trustee with
certificates for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company. 
  
 (l) The Company will comply with all rules and regulations of the Commission to the extent and so long as
they are applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying
the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter commencing after
the effective date of the Registration Statement, which statement shall cover such 12-month period. 
  
 (m) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and
containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to
the applicable provisions of the Indenture. 
  

 7 

 (n) The Company may require each Holder of Securities to be sold pursuant to the Shelf
Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company
may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 
  
 (o) The Company shall enter into such customary agreements (including, if requested, an underwriting
agreement in customary form) and take all such other action, if any, as Holders of not less than a majority of the aggregate principal amount of the Securities to be included in the Registration Statement shall reasonably request in order to
facilitate the disposition of the Securities pursuant to any Shelf Registration Statement. 
  
 (p) In the case of any Shelf Registration, the Company shall (i) make reasonably available for inspection by the Holders of the
Securities, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of the Securities or any such underwriter all relevant financial and other
records, pertinent corporate documents and properties of the Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders of the Securities
or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11
of the Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such
other parties as described in Section 4 hereof and shall be subject to any confidentiality procedures reasonably instituted by the Company and reasonably approved by you. 
  
 (q) In the case of any Shelf Registration, the Company, if requested by the Holders of at least a majority
of the aggregate principal amount of the Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any,
thereof and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation but subject to customary and reasonable
qualifications and exceptions, the due incorporation and good standing of the Company and its subsidiaries; the qualification of the Company and its subsidiaries to transact business as foreign corporations; the due authorization, execution and
delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution, authentication and issuance, and the validity and enforceability, of the applicable Securities; the absence of material legal or
governmental proceedings involving the Company and its subsidiaries; the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the applicable Securities, or any
agreement of the type referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the
Trust Indenture Act, respectively; and, as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence from such Shelf Registration
Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference therein of an untrue statement of a material fact or the omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its
officers to execute and deliver all customary documents and certificates and updates thereof requested by any underwriters of the applicable Securities and (iii) its independent public accountants to provide to the selling Holders of the applicable
Securities and any 

  

 8 

 
underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary
underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72. 
  
 (r) In the case of the Registered Exchange Offer, if requested by any Initial Purchaser or any known Participating Broker-Dealer, the
Company shall cause (i) its counsel to deliver to such Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set forth in Section 6(c) and (d) of the Purchase Agreement with such changes as are customary in connection
with the preparation of a Registration Statement and (ii) its independent public accountants to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the substance
thereof as set forth in Section 6(a) of the Purchase Agreement, with appropriate date changes. 
  
 (s) If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Securities by Holders to the
Company (or to such other Person as directed by the Company) in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company shall mark, or cause to be marked, on the Initial Securities so exchanged that
such Initial Securities are being canceled in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial Securities be marked as paid or otherwise satisfied. 
  
 (t) The Company will use its reasonable best efforts to (a)
if the Initial Securities have been rated prior to the initial sale of such Initial Securities, confirm such ratings will apply to the Securities covered by a Registration Statement, or (b) if the Initial Securities were not previously rated, cause
the Securities covered by a Registration Statement to be rated with the appropriate rating agencies, if so requested by Holders of a majority in aggregate principal amount of Securities covered by such Registration Statement, or by the managing
underwriters, if any. 
  
 (u) In the event that
any broker-dealer registered under the Exchange Act shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the
“Rules”) of the National Association of Securities Dealers, Inc. (“NASD”)) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise,
the Company will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by (i) if such Rules, including Rule 2720, shall so require, engaging a “qualified independent underwriter” (as
defined in Rule 2720) to participate in the preparation of the Registration Statement relating to such Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Registration
Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters
provided in Section 5 hereof and (iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 
  
 (v) The Company shall use its reasonable best efforts to take all other steps necessary to effect the
registration of the Securities covered by a Registration Statement contemplated hereby. 
  
 4. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance of its obligations under Sections 1 through 3 hereof (including the reasonable fees and
expenses, if any, of Cravath, Swaine & Moore LLP, counsel for the Initial Purchasers, incurred in connection with the Registered Exchange Offer), whether or not the Exchange Offer Registration Statement or a Shelf Registration Statement is filed
or becomes effective, and, in the event of a Shelf Registration, shall bear or reimburse the Holders of the Securities covered thereby for the reasonable fees and disbursements of one firm of counsel designated by the Holders of a majority in
principal amount of the 

  

 9 

 
Initial Securities covered thereby to act as counsel for the Holders of the Initial Securities in connection therewith. 
  
 5. Indemnification. (a) The Company agrees to indemnify and hold
harmless each Holder of the Securities, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any
Participating Broker-Dealer and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof
(including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement
thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect
thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged
omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder
and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf
Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the
Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage
or liability of such Holder or Participating Broker-Dealer results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final prospectus
if the Company had previously furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such
Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with
respect to the indemnification of the Holders of the Securities if requested by such Holders. 
  
 (b) Each Holder of the Securities, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and each
of its officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any
such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration Statement, or arise out of or are based upon the omission or alleged
omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in
conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall
reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This

  

 10 

 
indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons. 

 
 (c) Promptly after receipt by an indemnified party under
this Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify
the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have under subsection (a) or (b) above except to the extent that it has been
materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party
otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein
and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the
indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party
under this Section 5 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the
indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded, based on the advice of legal counsel, that there may be legal
defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified
party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or
related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm for any Purchaser, its affiliates, directors and officers and any control persons of such Purchaser shall be designated in writing by CSFB and any such separate firm for the Company, the Guarantors, their directors
and officers and any control persons of the Company and the Guarantors shall be designated in writing by the Company. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party
from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
  
 (d) If the indemnification provided for in this Section 5 is
unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party
on the other from the exchange of the Initial Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the indemnified 

  

 11 

 
party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect
thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section
5(d), the Holders of the Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of
damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the
Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company. 
  
 (e) The
agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made
by or on behalf of any indemnified party. 
  
 6. Additional
Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”) with respect to the Initial Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through
(vi) below a “Registration Default”: 
  
 (i) If the Company fails to file an Exchange Offer Registration Statement with the Commission on or prior to the 90th day after the Issue Date, 
  
 (ii) If the Exchange Offer Registration Statement is not declared effective by the Commission on or prior to the 180th day after the Issue
Date or, if filing a Shelf Registration Statement in the circumstances referenced in clause 2(i) above, a Shelf Registration Statement is not declared effective by the Commission on or prior to the 180th day after the Issue Date, 
  
 (iii) if the Exchange Offer is not consummated on or before
the 40th day after the Exchange Offer Registration Statement is declared effective, 
  
 (iv) if filing a Shelf Registration Statement in the circumstances referenced in clause 2(ii), (iii) or (iv) above, the Company fails to
file the Shelf Registration Statement with the Commission on or prior to the 60th day (the “Shelf Filing Date”) after the date on which the obligation to file a Shelf Registration Statement arises, 
  
 (v) if filing a Shelf Registration Statement in the
circumstances referenced in clause 2(ii), (iii) or (iv) above, the Shelf Registration Statement is not declared effective on or prior to the 60th day after the Shelf Filing Date, or 
  
 (vi) after the Exchange Offer Registration Statement or the Shelf Registration Statement, as the case may
be, is declared effective, (A) such Registration Statement 

  

 12 

 
thereafter ceases to be effective; or (B) such Registration Statement or the related prospectus ceases to be usable (except as permitted in paragraph (b)) in
connection with resales of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue
statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or (2) it shall be necessary to amend such Registration Statement
or supplement the related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder. 
  
 Additional Interest shall accrue on the Initial Securities over and above the interest set forth in the title of the Securities from and including the date on which any
such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of 0.25% per annum for the first 90-day period immediately following the occurrence of a Registration Default, and
such rate will increase by an additional 0.25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of 2.0% per annum. Such Additional Interest will be in
addition to any other interest payable from time to time with respect to the Initial Securities and the Exchange Notes. 
  
 (b) A Registration Default referred to in Section 6(a)(vi)(B) hereof shall be deemed not to have occurred and be continuing in relation to
a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited financial
information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events, with respect to the Company that would
need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related
prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in accordance with the above paragraph from the day such
Registration Default occurs until such Registration Default is cured. 
  
 (c) Any amounts of Additional Interest due pursuant to Section 6(a) above will be payable in cash on the regular interest payment dates with respect to the Initial Securities. The amount of Additional Interest will be
determined by multiplying the applicable Additional Interest rate by the principal amount of the Initial Securities, multiplied by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such
period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. 
  
 (d) “Transfer Restricted Securities” means each Security until (i) the date on which such Transfer Restricted Security has been
exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an Initial Security for an Exchange
Note, the date on which such Exchange Note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement, (iii) the date on which such
Initial Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (iv) the date on which such Initial Securities is distributed to the public pursuant to Rule 144 under
the Securities Act or is saleable pursuant to Rule 144(k) under the Securities Act. 
  
 7. Rules 144 and 144A. The Company shall use its reasonable best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the
Company is not required to file such reports, it will, upon the request of any Holder of Initial 

  

 13 

 
Securities, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company
covenants that it will take such further action as any Holder of Initial Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Initial Securities without registration under the Securities Act
within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Initial Securities identified to the Company by
the Initial Purchasers upon request. Upon the request of any Holder of Initial Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in
this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. 
  
 8. Underwritten Registrations. If any of the Transfer Restricted Securities covered by any Shelf Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers that will administer the offering (“Managing Underwriters”) will be selected by the Holders of a majority in aggregate principal amount of such Transfer
Restricted Securities to be included in such offering. 
  
 No
person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons
entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.
Except as provided in Section 4, the Holders participating in any underwritten offering shall be responsible for any expenses customarily borne by selling securityholders, including underwriting discounts and commissions and fees and expenses of
counsel to selling securityholders. 
  
 9. Miscellaneous.

  
 (a) Amendments and Waivers. The
provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal
amount of the Securities affected by such amendment, modification, supplement, waiver or consents. 
  
 (b) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery,

 (i) Securities Held by the Company. Whenever the consent or approval of Holders of a specified percentage of principal amount of
Securities is required hereunder, Securities held by the Company or its affiliates (other than subsequent Holders of Securities if such subsequent Holders 

  

 15 

 
are deemed to be affiliates solely by reason of their holdings of such Securities) shall not be counted in determining whether such consent or approval was
given by the Holders of such required percentage.

Issuer a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the several Initial Purchasers and the Company in accordance with its terms.

 ANNEX A 
  
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning
of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial
Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.” 
  

 ANNEX B 
  
 Each broker-dealer that receives Exchange Securities for its own account in exchange for Securities, where such Initial Securities were acquired by such
broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.” 
  

 ANNEX C 
  
 PLAN OF DISTRIBUTION 
  
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial
Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the Expiration Date, it will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until             , 200 , all dealers effecting transactions in the Exchange Securities
may be required to deliver a prospectus.(1) 
  
 The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their
own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the
Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities
and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. 
  
 For a period of 180 days after the Expiration Date the Company will promptly send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to the Exchange Offer (including the expenses of one counsel for the Holders of the Securities) other
than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Securities (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. 

	(1)	 	In addition, the legend required by Item 502(e) of Regulation S-K will appear on the back cover page of the Exchange Offer prospectus.

 If the undersigned is not a
broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of Exchange Securities. If the undersigned is a broker-dealer that will receive Exchange Securities for its own account in exchange
for Initial Securities that were acquired as a result of market-making activities or other trading activities, it acknowledges that it will deliver a prospectus in connection with any resale of such Exchange Securities; however, by so acknowledging
and by delivering a prospectus, the undersigned will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.
