 THE NOTES 
  
 Section 2.01. Form and Dating. 
  
 The Initial Notes and the Additional Notes and the Trustee’s
certificate of authentication thereon shall be substantially in the form of Exhibit A hereto. The Exchange Notes and the Trustee’s certificate of authentication thereon shall be substantially in the form of Exhibit B hereto. The
Notes may have notations, legends or endorsements required by law, stock exchange rule or DTC rule or usage. The Company and the Trustee shall approve the form of the Notes and any notation, legend or endorsement on them. Each Note shall be dated
the date of its authentication. 
  
 The terms and provisions
contained in the forms of the Notes annexed hereto as Exhibit A and Exhibit B, shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by
their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 
  
 Notes offered and sold in reliance on Rule 144A shall be issued initially in the form of one or more permanent global notes in registered form,
substantially in the form set forth in Exhibit A (the “144A Global Notes”), deposited with the Trustee, as custodian for DTC, duly executed by the Company and authenticated by the Trustee as hereinafter provided and shall
bear the legend set forth in Exhibit C. 
  
 Notes offered
and sold to Institutional Accredited Investors in reliance on Rule 501(a)(1), (2), (3) or (7) under the Securities Act shall be issued initially in the form of one or more permanent global notes in registered form, substantially in the form set
forth in Exhibit A (the “IAI Global Notes”), deposited with the Trustee, as custodian for DTC, duly executed by the Company and authenticated by the Trustee as hereinafter provided and shall bear the legend set forth in

 Notes offered and sold in offshore

nominee of the 
  

 27 

 Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the
Company and authenticated by the Trustee as hereinafter provided and shall bear the legend set forth in Exhibit C. 
  
 Following the termination of the Restricted Period, beneficial interests in a Regulation S Temporary Global Note will be exchanged for beneficial
interests in a Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the authentication of a Regulation S Permanent Global Note, the Trustee will cancel the related Regulation S Temporary Global Note.

  
 The provisions of the “Operating Procedures of the
Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of
beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Note that are held by participants through Euroclear or Clearsteam. 
  
 The aggregate principal amount of any Global Note may from time to time be increased or decreased by adjustments made on the
records of the Trustee, as custodian for DTC, as hereinafter provided. 
  
 The definitive Notes shall be typed, printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which the Notes may be
listed, all as determined by the Officer executing such Notes, as evidenced by their execution of such Notes. 
  
 Section 2.02. Execution and Authentication; Aggregate Principal Amount. 
  
 An Officer (who shall have been duly authorized by all requisite corporate
actions) shall sign the Notes for the Company by manual or facsimile signature. 
  
 If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office or position at the time the Trustee authenticates the Note, the Note shall nevertheless be valid.

  
 A Note shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
  
 The Trustee shall authenticate (i) Initial Notes for original issue in the aggregate principal amount not to exceed
$80,000,000, (ii) Exchange Notes from time to time for issue only in exchange for a like principal amount of Initial Notes or Additional Notes, and (iii) subject to compliance with Section 4.08, one or more series of Additional Notes in an
unlimited amount in each case upon written orders of the Company in the form of an Officers’ Certificate, which Officers’ Certificate shall, in the case of any issuance of Additional Notes, certify that such issuance is in compliance with
Section 4.08. In addition, each Officers’ Certificate shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Initial Notes, Exchange Notes or Additional
Notes. All Notes issued under this Indenture shall vote and consent together on all matters as one class and no series of Notes shall have the right to vote or consent as a separate class on any matter. 
  
 The Trustee may appoint an authenticating agent (the “Authenticating
Agent”) reasonably acceptable to the Company to authenticate Notes. Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this 
  

 28 

 Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An Authenticating Agent
has the same rights as an Agent to deal with the Company and Affiliates of the Company. 
  
 The Notes shall be issuable in fully registered form only, without coupons, in denominations of $1,000 in principal amount and any integral multiple thereof. 
  
 Section 2.03. Registrar and Paying Agent. 

 
 The Company shall maintain an office or agency which shall initially be
the office of U.S. Bank Trust National Association, an Affiliate of the Trustee, in the Borough of Manhattan, The City of New York, where (a) Notes may be presented or surrendered for registration of transfer or for exchange (the
“Registrar”), (b) Notes may be presented or surrendered for payment (the “Paying Agent”) and (c) notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Registrar
shall keep a register of the Notes and of their transfer and exchange (the “Register”). The Company, upon prior written notice to the Trustee, may have one or more co-Registrars and one or more additional Paying Agents reasonably
acceptable to the Trustee. The term “Paying Agent” includes any additional Paying Agent. Neither the Company nor any Affiliate of the Company may act as Paying Agent. 
  
 The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement
shall incorporate the provisions of the TIA and implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in writing, in advance, of the name and address of any such Agent and otherwise be reasonably
satisfactory to the Trustee. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such. 
  

The Company initially appoints each of the Trustee and U.S. Bank Trust National Association, an Affiliate of the Trustee, as Registrar, Paying Agent
and agent for service of demands and notices in connection with the Notes. Any Paying Agent or Registrar may resign upon thirty (30) days’ written notice to the Company. 
  
 Section 2.04. Obligations of Paying Agent. 
  
 The Company shall require each Paying Agent other than the Trustee to agree
in writing that such Paying Agent shall hold separate and apart from, and not commingle with any other properties, for the benefit of the Holders or the Trustee, all assets held by the Paying Agent for the payment of principal of, or interest and
Additional Interest, if any, on, the Notes (whether such assets have been distributed to it by the Company or any other obligor on the Notes), and the Company and the Paying Agent shall notify the Trustee in writing of any Default by the Company (or
any other obligor on the Notes) in making any such payment. The Company at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the
continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon receipt by the Trustee of all assets that shall
have been delivered by the Company to the Paying Agent, the Paying Agent shall have no further liability for such assets. 
  
 Section 2.05. Holder Lists. 
  
 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the
Holders and shall otherwise comply with TIA 
  

 29 

 Section 312(a). If the Trustee is not the Registrar, the Company shall furnish or cause the Registrar to furnish to the
Trustee before each Record Date and at such other times as the Trustee may request in writing a list as of such date and in such form as the Trustee may reasonably request of the names and addresses of the Holders, which list may be conclusively
relied upon by the Trustee. 
  
 Section 2.06.
Transfer and Exchange. 
  
 Subject to the provisions of
Sections 2.14 and 2.15, when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized
denominations, the Registrar or co-Registrar shall register the transfer or make the exchange as requested; provided, however, that the Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing and such other documents as the Registrar or
co-Registrar may reasonably require. To permit registrations of transfers and exchanges, the Company shall issue and the Trustee shall authenticate Notes at the Registrar’s or co-Registrar’s request. No service charge shall be made for any
registration of transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchanges or transfers pursuant to Section 2.10, 3.06, 4.10 or 4.23, in which event the Company shall be responsible for the payment of such taxes). 
  
 The Registrar or co-Registrar shall not be required to register the transfer
or exchange of any Note (i) during a period beginning at the opening of business fifteen (15) days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing and (ii) selected for redemption
in whole or in part pursuant to Article Three, except the unredeemed portion of any Note being redeemed in part. 
  
 Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Note may be effected
only through DTC, in accordance with this Indenture and the Applicable Procedures. 
  
 Section 2.07. Replacement Notes. 
  
 If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims in writing that the Note has been lost, destroyed or wrongfully taken,
then, in the absence of written notice to the Company upon its request or the Trustee that such Note has been acquired by a protected purchaser, the Company shall issue and the Trustee shall authenticate a replacement Note of like tenor and
principal amount and bearing a number not contemporaneously outstanding if the Trustee’s requirements are met. Except with respect to mutilated Notes, if required by the Trustee or the Company, such Holder must provide an affidavit of lost
certificate and an indemnity bond or other indemnity reasonably satisfactory to the Company, sufficient in the judgment of both the Company and the Trustee, to protect the Company, the Trustee or any Agent from any loss which any of them may suffer
if a Note is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note, including reasonable fees and expenses of its counsel and of the Trustee and its counsel. In case any mutilated, lost, destroyed
or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. Every replacement Note shall constitute an additional obligation of the
Company, entitled to the benefits of this Indenture. 
  

 30 

 Section 2.08. Outstanding Notes. 
  
 Notes outstanding at any time are all the Notes that have been authenticated
by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Subject to the provisions of Section 2.09, a Note does not cease to be outstanding because
the Company or any of its Affiliates holds the Note. 
  
 If a Note
is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless each of the Company and the Trustee receives proof satisfactory to it that the replaced Note is held by a
bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07. 
  
 If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the
principal and interest, and Additional Interest, if any, due on the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes cease
to be outstanding and interest, and Additional Interest, if applicable, on them ceases to accrue. 
  
 Section 2.09. Treasury Notes; When Notes are Disregarded. 
  
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or
consent, Notes owned by the Company or any of its Affiliates shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes which the Trustee actually knows are so owned shall be so considered. Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or of such other obligor. The Company shall notify the Trustee, in writing (which
notice shall constitute actual notice for purposes of the foregoing sentence), when it or any of its Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired.

  
 Section 2.10. Temporary Notes.

  
 Until definitive Notes are ready for delivery, the Company
may prepare and execute and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Company in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without
unreasonable delay, the Company shall prepare and the Trustee shall authenticate upon receipt of a written order of the Company pursuant to Section 2.02 definitive Notes in exchange for temporary Notes. Until so exchanged, the temporary Notes
shall be entitled to the same benefits under this Indenture as definitive Notes. 
  
 Section 2.11. Cancellation. 
  
 The Company at any time may deliver Notes previously authenticated hereunder which the Company has acquired in any lawful manner, to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall
cancel all Notes surrendered for transfer, exchange, payment or cancellation. Subject to 
  

 31 

 Section 2.07, the Company may not issue new Notes to replace Notes that it has paid or delivered to the Trustee
for cancellation. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for
cancellation pursuant to this Section 2.11. The Trustee shall dispose of all cancelled Notes in accordance with customary procedures or, at the written request of the Company, shall return the same to the Company. 
  
 Section 2.12. CUSIP Numbers. 
  
 A “CUSIP” number shall be printed on the Notes, and the
Trustee shall use the CUSIP number in notices of redemption, purchase or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee of any change in the CUSIP number. 
  
 Section 2.13. Deposit of Moneys. 
  
 Prior to 11:00 a.m. New York City time on each Interest Payment Date and the
Maturity Date, the Company shall deposit with the Paying Agent U.S. Legal Tender sufficient to make cash payments, if any, due on such Interest Payment Date or the Maturity Date, as the case may be. 
  
 Section 2.14. Book-Entry Provisions for Global Notes.

  
 (a) The Global Notes initially shall (i) be registered in the
name of DTC or the nominee of DTC, (ii) be delivered to the Trustee as custodian for DTC and (iii) bear legends as set forth in Exhibit C. 
  
 Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on
their behalf by DTC, or the Trustee as its custodian, or under any Global Note, and DTC may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC
and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 
  
 (b) Transfers of the Global Notes shall be limited to transfers in whole, but not in part, to DTC, its successors or their respective nominees. Interests
of beneficial owners in the Global Notes may be transferred or exchanged in accordance with the Applicable Procedures of DTC and the provisions of Section 2.15; provided, however, that prior to the expiration of the Restricted
Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). In addition, Notes in the form of certificated
Notes in registered form in substantially the form set forth in Exhibit A hereto (the “Physical Notes”) shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Notes if (i) DTC
notifies the Company that it is unwilling or unable to continue as depository for the Global Notes and a successor Depository is not appointed by the Company within ninety (90) days of such notice or (ii) an Event of Default has occurred and is
continuing and the Registrar has received a request from DTC to issue Physical Notes; provided that a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for a Physical Note or transferred to a Person who takes
delivery thereof in the form of a Physical Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the 
  

 32 

 Securities Act, except in the case of a transfer pursuant to an exemption from the registration requirements of the
Securities Act other than Rule 903 or Rule 904. 
  
 (c) Any
beneficial interest in one of the Global Notes that is transferred to a person who takes delivery in the form of an interest in another Global Note shall, upon transfer, cease to be an interest in such Global Note and become a beneficial interest in
such other Global Note and, accordingly, shall thereafter be subject to all transfer restrictions, if any, and other procedures applicable to a beneficial interest in such other Global Notes for as long as it remains such an interest. 
  
 (d) In connection with any transfer or exchange of a portion of the
beneficial interest in the Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.14, the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease
in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more
Physical Notes of like tenor and aggregate principal amount. 
  
 (e) In connection with the transfer of an entire Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.14, the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount of Physical Notes of authorized
denominations. 
  
 (f) Any Physical Note constituting a Restricted
Security delivered in exchange for an interest in the Global Note pursuant to paragraph (b) or (c) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 2.15, bear the legend regarding
transfer restrictions applicable to the Physical Notes set forth in Exhibit A. 
  
 (g) The Holder of a Global Note may 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 Notes. 
  
 Section 2.15. Special Transfer Provisions. 
  
 (a) Transfers to Non-QIB Institutional Accredited Investors and Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to any
Institutional Accredited Investor which is not a QIB or to any Non-U.S. Person: 
  
 (i) the Registrar shall register the transfer of any Note constituting a Restricted Security, whether or not such Note bears the Private
Placement Legend, if (x) the requested transfer is after August 12, 2006 or (y) (1) in the case of a transfer to an Institutional Accredited Investor which is not a QIB (excluding Non-U.S. Persons), the proposed transferee has delivered to the
Registrar a certificate substantially in the form of Exhibit D hereto or (2) in the case of a transfer to a Non-U.S. Person, the proposed transferor has delivered to the Registrar a certificate substantially in the form of Exhibit E
hereto; and 
  
 (ii) if the proposed transferor
is an Agent Member holding a beneficial interest in the Global Note, upon receipt by the Registrar of (x) the certificate, if any, required by paragraph (i) above and (y) instructions given in accordance with the Applicable Procedures and the
Registrar’s procedures, 
  

 33 

 whereupon (1) the Registrar shall reflect on its books and records the date and (if the transfer does not involve a
transfer of outstanding Physical Notes) a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and (2) the Company shall execute and the
Trustee shall authenticate and deliver one or more Physical Notes of like tenor and principal amount. 
  
 (b) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a
Restricted Security to a QIB (excluding transfers to Non-U.S. Persons): 
  
 (i) the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Note stating, or has otherwise advised the Company and the
Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Note stating, or has otherwise advised the Company and the Registrar in
writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is
being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is
relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and 
  
 (ii) if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to
be evidenced by an interest in the Global Note, upon receipt by the Registrar of instructions given in accordance with the Applicable Procedures and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and
an increase in the principal amount of the Global Note in an amount equal to the principal amount of the Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred. 
  
 (c) Private Placement Legend. Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Notes bearing the Private Placement Legend, the Registrar
shall deliver only Notes that bear the Private Placement Legend unless (i) the circumstance contemplated by paragraph (a)(i)(x) of this Section 2.15 exists or (ii) there is delivered to the Registrar an Opinion of Counsel reasonably
satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. The Registrar shall not register a
transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set forth in this Indenture. In connection with any transfer of Notes, each Holder agrees by its acceptance of the Notes to furnish the Registrar or
the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

  
 (d) General. By its acceptance of any Note bearing the
Private Placement Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it shall transfer such Note only as provided in this
Indenture. 
  

 34 

 The Registrar shall retain copies of all letters, notices and other written communications received
pursuant to Section 2.14 or this Section 2.15. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice
to the Registrar. 
  
 The Trustee shall have no obligation or duty
to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members
or beneficial owners of interests in any Global Note) 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. 
  
 Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by DTC. 
  
 Section 2.16. Transfers of Global Notes and Physical
Notes. 
  
 A transfer of a Global Note or a Physical Note
(including the right to receive principal and interest, and Additional Interest, if any, payable thereon) may be made only by the Registrar’s entering the transfer in the Register. Prior to such entry, the Company shall treat the person in
whose name such Note is registered as the owner of the Note for all purposes.

 REDEMPTION 
  
 Section 3.01.
Optional Redemption. 
  
 The Company may, at its option,
redeem the Notes, in whole or in part, at specified times and under specified conditions, as set forth in Paragraph 5 of the Notes. If the Company elects to redeem Notes pursuant to Paragraph 5 of the Notes, it shall, at least thirty-five (35) days
(or such shorter period as the Trustee may agree) before the Redemption Date, notify to the Trustee and Paying Agent in writing of the Redemption Date and the principal amount of the Notes to be redeemed and the clause of this Indenture or the Notes
pursuant to which the redemption shall occur. 
  
 Each
Officers’ Certificate provided for in this Section 3.01 shall be accompanied by an Opinion of Counsel stating that such redemption shall comply with the conditions contained herein and in the Notes.

(2) if such Notes are not then listed on a national securities exchange, on a pro rata basis by lot or by such method as the Trustee may
reasonably determine is fair and appropriate; provided that

 no partial redemption will reduce the principal amount of a Note not redeemed to less than $1,000; and provided
further, that if a partial redemption is made with the proceeds of an Equity Offering then the selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro
rata basis as is practicable (subject to the procedures of DTC), unless such method is prohibited. 
  
 The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Company in writing
of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount at maturity thereof, to be redeemed. Notes in denominations of $1,000 in principal amount at maturity may be redeemed only in
whole. The Trustee may select for redemption portions (equal to $1,000 in principal amount at maturity or any integral multiple thereof) of the principal of Notes that have denominations larger than $1,000. Provisions of this Indenture that apply to
Notes called for redemption also apply to portions of Notes called for redemption. 
  
 Section 3.03. Notice of Redemption. 
  
 At least thirty (30) days but not more than sixty (60) days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption
by first class mail, postage prepaid, to each Holder whose Notes are to be redeemed at its registered address, with a copy to the Trustee and any Paying Agent. At the Company’s written request, the Trustee shall give the notice of redemption in
the Company’s name and at the Company’s expense. Failure to give notice of redemption, or any defect therein to any Holder of any Note selected for redemption shall not impair or affect the validity of the redemption of any other Note.

  
 Each notice of redemption shall identify the Notes to be

of accrued interest and Additional Interest, if any, to be paid to (but not including) the Redemption Date; 
  
 (3) the name and address of the Paying Agent;

 (5) the subparagraph of the Notes pursuant to which such redemption is being made; 
  
 (6) the place where such Notes called for redemption must be
surrendered to the Paying Agent to collect the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date; 
  
 (7) that, unless the Company fails to deposit with the Paying Agent funds in satisfaction of the applicable
redemption price, interest and Additional Interest, if any, on Notes called for redemption ceases to accrue on and after the Redemption Date in accordance with Section 3.05, and the only remaining right of the Holders of such Notes is to
receive payment of the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date, upon surrender to the Paying Agent of the Notes redeemed; 
  
 (8) if any Note is being redeemed in part, the portion of
the principal amount of such Note to be redeemed and that, after the Redemption Date, and upon surrender of such Note, a new 
  

 36 

 Note or Notes in the aggregate principal amount equal to the unredeemed portion thereof shall be issued;
and 
  
 (9) if fewer than all the Notes are to be
redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption.

 Once notice of redemption is mailed in accordance with Section 3.03, Notes or portions thereof called for redemption
shall become irrevocably due and payable on the Redemption Date and at the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date. Upon surrender to the Trustee or Paying Agent, such Notes
or portions thereof called for redemption shall be paid at the Redemption Price plus accrued interest and Additional Interest, if any, thereon to (but not including) the Redemption Date, but installments of interest, the maturity of which is on or
prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates referred to in the Notes. 
  
 Section 3.05. Deposit of Redemption Price. 
  
 Not later than 10:00 a.m. local time in the place of payment on the Redemption Date, the Company shall deposit with the
Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date, of all Notes or portions thereof to be redeemed on that date. 
  
 The Paying Agent shall promptly return to the Company any U.S. Legal Tender
so deposited which is not required for that purpose, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven. 
  
 If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of such Redemption Price plus accrued interest and
Additional Interest, if any, to (but not including) the Redemption Date, on the Notes to be redeemed shall cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment. 
  
 Section 3.06. Notes Redeemed in Part. 
  
 Upon surrender of a Note that is to be redeemed in part, the Company shall
issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note or Notes equal in principal amount to the unredeemed portion of the Note surrendered.

principal of, premium, if any, or interest or Additional Interest, if any, on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to
the extent that it may lawfully do so) the Company hereby expressly waives all benefit or advantage of any such law, and covenant that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the

assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, “incur”) any Indebtedness (other than Permitted Indebtedness); provided,
however, that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Company or any of its Restricted Subsidiaries that is or, upon such

such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Obligations of the Company or such Domestic Restricted Subsidiary under (a) in the case of the Company, the Notes
and this Indenture or (b) in the case of such Domestic Restricted Subsidiary, its Guarantee and this Indenture, in each case, to the same extent and in the same manner as such Indebtedness is subordinated pursuant to subordination provisions that
are most favorable to the holders of any other Indebtedness of the Company or such Domestic Restricted Subsidiary.

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

thereof) shall exceed the sum of: 
  
 (A) 50% of
the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income is a loss, minus 100% of such loss) of the Company earned during the period beginning on May 1, 2005 and ending on the last day of the Company’s most recent fiscal
quarter ending prior to the date the Restricted Payment occurs for which financial statements are available (the ”Reference Date”) (treating such period as a single accounting period); plus 
  
 (B) 100% of the aggregate net cash proceeds received by the
Company from any Person (other than a Subsidiary of the Company) from the issuance and sale subsequent to the Issue Date and on or prior to the Reference Date of Qualified Capital Stock of the Company (excluding any net proceeds from an Equity
Offering to the extent used to redeem Notes pursuant to Section 5(c) of the Notes; plus 
  
 (C) 100% of the aggregate net cash proceeds received from the issuance of Indebtedness or shares of Disqualified Capital Stock of the
Company that have been converted into or exchanged for Qualified Capital Stock of the Company subsequent to the Issue Date and on or prior to the Reference Date; plus 
  
 (D) an amount equal to the sum of (i) the net reduction in the Investments (other than Permitted
Investments) made by the Company or any of its Restricted Subsidiaries in any Person resulting from repurchases, repayments or redemptions of such Investments by such Person, proceeds realized on the sale of such Investment and proceeds representing
the return of capital (excluding dividends and distributions), in each case received by the Company or any of its Restricted Subsidiaries, and (ii) to the 
  

 41 

 extent such Person is an Unrestricted Subsidiary, 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 at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that the foregoing sum
shall not exceed, in the case of any such Person or Unrestricted Subsidiary, the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any of its Restricted Subsidiaries in
such Person or Unrestricted Subsidiary; plus 
  
 (E) 100% of the aggregate net cash proceeds received from the exercise by any holder of a convertible note of the Company that has been converted into Qualified Capital Stock of the Company subsequent to the Issue Date and on or prior to
the Reference Date. 
  
 In the case of clause (iv)(B) or (E) above, any net cash
proceeds from issuances and sales of Qualified Capital Stock of the Company financed directly or indirectly using funds borrowed from the Company or any Subsidiary of the Company, shall be excluded until and to the extent such borrowing is repaid.

  
 Notwithstanding the foregoing, the provisions set forth in the
immediately preceding paragraph do not prohibit: 
  
 (2) the payment of any dividend or other distribution or redemption within 60 days after the date of declaration of such dividend or call for redemption if such payment would have been permitted on the date of declaration or call for
redemption;

 (6) if no Default or Event of Default has occurred and is continuing or would exist after giving effect
thereto, the repurchase or other acquisition of shares of Capital Stock of the Company from employees, former employees, directors or former directors of the Company (or permitted transferees of such employees, former employees, directors or former

 42

provided further, however, that such amount in any calendar year may be increased by an amount not to exceed the net cash proceeds of key man life insurance policies received by the Company after the Issue Date; 
  
 (7) repurchases of Capital Stock deemed to occur upon
exercise of stock options, warrants or other similar rights if such Capital Stock represents a portion of the exercise price of such options, warrants or other similar rights; 
  
 (8) payments or distributions to dissenting stockholders of Capital Stock of the Company pursuant to

Section 4.09 amounts expended pursuant to clauses (1), (2)(ii), 3(ii)(a), (4)(ii) and (9) of the immediately preceding paragraph shall be included in such calculation. 
  
 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 complies with this Indenture and setting forth in reasonable detail the basis upon which the required calculations were computed, which calculations may be
based upon the Company’s latest available internal quarterly financial statements. 
  
 Section 4.10. Limitation on Asset Sales. 
  

The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
  
 (1) the Company or the applicable Restricted Subsidiary, as
the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets sold or otherwise disposed; 
  
 (2) at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale is in
the form of cash or Cash Equivalents and is received at the time of such disposition; provided that the amount of any liabilities (as shown on the most recent applicable balance sheet) of the Company or such Restricted Subsidiary (other than
liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets shall be deemed to be cash for purposes of this provision so long as the documents governing such liabilities provide that there is
no further recourse to the Company or any of its Subsidiaries with respect to such liabilities; and 
  

 43 

 (3) the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash
Proceeds relating to such Asset Sale within 360 days of receipt thereof either: 
  
 (a) to repay (i) Permitted Indebtedness of the Company or any Restricted Subsidiary of the type described in (A) clause (3) of the
definition thereof that is secured by Permitted Liens of the type described in clause (14) of the definition thereof, (B) clause (10) of the definition thereof that is secured by Permitted Liens of the type described in clause
(6) or (7) of the definition thereof, or (C) clause (11) of the definition thereof that is secured by Permitted Liens of the type described in clause (17) of the definition thereof or (ii) Indebtedness of the type described
in clause (13) of the definition of the term Permitted Liens that is secured by Permitted Liens of the type described in clause (13) of the definition thereof, in each case, to the extent such Indebtedness is not by its terms
subordinated to the Notes or the Guarantees and such Permitted Liens are not subordinated to Permitted Liens of the type describe in clause (15) of the definition thereof; 
  
 (b) to the extent that the assets and property sold pursuant to such Asset Sale constitute Shared
Collateral of (i) the Company or any Guarantor (other than the Railway Subsidiary), to repay Indebtedness under the Credit Agreement or (ii) the Railway Subsidiary, to repay (A) Indebtedness under the Credit Agreement (and permanently reduce the
commitments thereunder) or (B) the Railway Term Loan; 
  
 (c) to make (or enter into a definitive agreement committing to do so within 180 days after the date that is 360 days following the date of receipt of such Net Cash Proceeds) an investment in property, plant, equipment or other non-current
assets that replace the properties and assets that were the subject of such Asset Sale or that will be used or useful in a Permitted Business (including expenditures for maintenance, repair or improvement of existing properties and assets) or the
acquisition of all of the Capital Stock of a Person engaged in a Permitted Business; or 
  
 (d) a combination of repayment and investment permitted by the foregoing clauses (3)(a), (3)(b) and (3)(c). 
  
 Pending the final application of Net Cash Proceeds, the Company may
temporarily reduce revolving credit borrowings or invest such Net Cash Proceeds in Cash Equivalents. On the 361st day after its receipt of Net Cash Proceeds relating to an Asset Sale or such earlier date, if any, as the Board of Directors of the
Company or of such Restricted Subsidiary determines not to apply such Net Cash Proceeds as set forth in clauses (3)(a), 3(b), 3(c) or 3(d) of the preceding paragraph (each, a ”Net Proceeds Offer Trigger Date”) (but subject to clause
(y) of the proviso in this sentence), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (3)(a), (3)(b), (3)(c) and 3(d) of the preceding paragraph (each a
”Net Proceeds Offer Amount”) shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the “Net Proceeds Offer”) on a date (the “Net Proceeds Offer Payment Date”)
not less than 30 nor more than 60 days following the applicable Net Proceeds Offer Trigger Date, from all Holders and all holders of other Applicable Indebtedness (other than Indebtedness of the type described in clause (3)(a) or (3)(b) of the
immediately preceding paragraph) containing provisions similar to those set forth in this Section 4.10 on a prorata basis, the maximum principal amount of Notes and such other Applicable Indebtedness that may be purchased with the Net
Proceeds Offer Amount at a price equal to 100% of the principal amount thereof (or if such Indebtedness was issued with original issue discount, 100% of the accreted value), plus accrued and unpaid interest and Additional Interest thereon, if any,
to the date of purchase; provided, however, that if (x) at any time any non-cash consideration received by the Company 
  

 44 

 or any Restricted Subsidiary of the Company, as the case may be, in connection with any Asset Sale is converted into or
sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder on the date of such conversion or
disposition, as the case may be, and the Net Cash Proceeds thereof shall be applied in accordance with this Section 4.10 and (y) any Net Cash Proceeds are not applied by the date provided in any definitive agreement described under clause
(3)(c) of the immediately preceding paragraph (as such date may be extended in accordance with the terms of such definitive agreement, but in any event, to a date no later than 180 days following such 361st date), such date (as extended, if
applicable) and the aggregate amount of such Net Cash Proceeds shall immediately be deemed to be a “Net Proceeds Trigger Date” and “Net Proceeds Offer Amount”, respectively, and such aggregate amount shall be subject to a Net
Proceeds Offer and such Net Cash Proceeds shall be applied in accordance with this paragraph. 
  
 The Company may defer any Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5.0 million resulting from one or more Asset Sales in which case the accumulation
of such amount shall constitute a Net Proceeds Offer Trigger Date (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5.0 million, shall be applied as required pursuant to the immediately preceding
paragraph). Upon the completion of each Net Proceeds Offer, the Net Proceeds Offer Amount will be reset at zero, and for the avoidance of doubt, if the aggregate principal amount of Notes properly tendered in connection with such Net Proceeds Offer
was less than the Net Proceeds Offer Amount, any Net Cash Proceeds relating to, and remaining following the completion of, such Net Proceeds Offer shall no longer constitute Net Cash Proceeds for purposes of this Section 4.10. 
  
 In the event of the transfer of substantially all (but not all) of the
property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted in Section 5.01, which transaction does not constitute a Change of Control, the successor entity shall be deemed to have
sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this Section 4.10, and shall comply with the provisions of this Section 4.10 with respect to such deemed sale as if it
constituted an Asset Sale. In addition, the Fair Market Value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section 4.10. 

 
 Each notice of a Net Proceeds Offer shall be mailed first class, postage
prepaid, to the record Holders as shown on the register of Holders within 20 days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with the procedures set forth in this Indenture. Upon receiving notice of
the Net Proceeds Offer, Holders may elect to tender their Notes in whole or in part in integral multiples of $1,000 in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of
tendering Holders will be purchased on a pro rata basis (based on amounts tendered). A Net Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law. 
  
 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 Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any

 Section
4.12. Limitation on Issuances and Sales of Capital Stock of Subsidiaries. 
  
 The Company will not permit or cause any of its Restricted Subsidiaries to issue or sell any Capital Stock (other than to the Company or to a Wholly-Owned Restricted Subsidiary of the Company) or permit any Person

 Section 4.14.
Limitations on Transactions with Affiliates. 
  
 (a) The
Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or
exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an “Affiliate Transaction”), other than 
  

 47 

 (x) Affiliate Transactions permitted under paragraph (b) below, and 
  
 (y) Affiliate Transactions on terms that are no less
favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary. 
  
 With respect to all Affiliate Transactions (other than those described in
clause (b) below), the Company shall deliver an Officers’ Certificate to the Trustee certifying that such transactions are in compliance with clause (a)(y) of the preceding paragraph. All Affiliate Transactions (and each series of
related Affiliate Transactions which are similar or part of a common plan) involving aggregate payments or other property with a Fair Market Value in excess of $2.5 million shall be approved by a majority of the members of the Board of Directors of
the Company (including a majority of the disinterested members thereof), as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing
provisions. If the Company or any Restricted Subsidiary of the Company enters into an Affiliate Transaction (or a series of related Affiliate Transactions related to a common plan) that involves an aggregate Fair Market Value of more than $5.0
million, the Company shall, prior to the consummation thereof, obtain a favorable opinion as to the fairness of the financial terms of such transaction or series of related transactions to the Company or the relevant Restricted Subsidiary, as the

provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary of the Company as determined in good faith by the Company’s Board of Directors or senior management; 
  
 (2) transactions exclusively between or among the Company
and any of its Restricted Subsidiaries or exclusively between or among such Restricted Subsidiaries; provided that such transactions are not otherwise prohibited by this Indenture; 
  
 (3) any agreement as in effect as of the Issue Date or any
transaction contemplated thereby and any amendment thereto or any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders in any material respect than the original agreement as
in effect on the Issue Date; 
  
 (4) Permitted
Investments of the type described under clauses (8), (9) and (11) of the definition thereof and Restricted Payments permitted by this Indenture; 
  
 (5) any merger or other transaction with an Affiliate solely for the purpose of reincorporating the Company
in another jurisdiction or creating a holding company of the Company; and 
  
 (6) any employment, stock option, stock repurchase, employee benefit compensation, business expense reimbursement, severance, termination or other employment-related agreements, arrangements or plans entered into by
the Company or any of its Restricted Subsidiaries in the ordinary course of business.

 Section 4.15. Additional Subsidiary Guarantees. 
  
 If the Company or any of its Restricted Subsidiaries acquires or creates
another Domestic Restricted Subsidiary after the Issue Date (other than an Unrestricted Subsidiary), then the Company shall cause such Domestic Restricted Subsidiary to: 
  
 (1) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the
Trustee pursuant to which such Domestic Restricted Subsidiary shall unconditionally guarantee on a senior secured basis all of the Company’s obligations under the Notes and this Indenture on the terms set forth in this Indenture; 
  
 (2) (a) execute and deliver to the Collateral Agent such
amendments to the Collateral Agreements as the Collateral Agent deems necessary or advisable in order to grant to the Collateral Agent, for the benefit of the Holders and the Lenders, a perfected security interest in the Capital Stock of such new
Domestic Restricted Subsidiary and any debt securities of such new Domestic Restricted Subsidiary, subject to the Permitted Liens, which are owned by the Company or such new Domestic Restricted Subsidiary and required to be pledged pursuant to the
Security Agreement, (b) deliver to the Collateral Agent any certificates representing such Capital Stock and debt securities, together with (i) in the case of such Capital Stock, undated stock powers or instruments of transfer, as applicable,
endorsed in blank, and (ii) in the case of such debt securities, endorsed in blank, in each case executed and delivered by an Officer of the Company or such Subsidiary, as the case may be; 
  
 (3) take such actions necessary or as the Collateral Agent
reasonably determines to be advisable to grant to the Collateral Agent for the benefit of the Holders a perfected security interest in the assets of such new Domestic Restricted Subsidiary, subject to the Permitted Liens, including the filing of
Uniform Commercial Code financing statements in such jurisdictions as may be required by the Security Agreement or by law or as may be reasonably requested by the Collateral Agent; 
  
 (4) take such further action and execute and deliver such other documents specified in this Indenture or
otherwise reasonably requested by the Trustee or the Collateral Agent to effectuate the foregoing; and 
  
 (5) deliver to the Trustee an Opinion of Counsel that such supplemental indenture and any other documents required to be delivered have
been duly authorized, executed and delivered by such Domestic Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligations of such Domestic Restricted Subsidiary and such other opinions regarding the perfection of such
Liens in the assets of such Domestic Restricted Subsidiary as provided for in this Indenture. 
  
 Thereafter, such Domestic Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture. 
  
 Section 4.16. Impairment of Security Interest. 
  
 Subject to the Intercreditor Agreement, neither the Company nor any of its Restricted Subsidiaries will take or omit to take
any action which would adversely affect or impair in any material respect the Liens in favor of the Collateral Agent with respect to the Collateral. Neither the Company nor any of its Domestic Restricted Subsidiaries shall grant to any Person (other
than the Collateral Agent), or permit any Person (other than the Collateral Agent), to retain any interest whatsoever in the Collateral other than Permitted Liens. Neither the Company nor any of its Restricted Subsidiaries will enter into

  

 49 

 any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or
otherwise acquire or retire any Indebtedness of any Person, other than as permitted by this Indenture, the Notes, the Intercreditor Agreement and the Collateral Agreements. The Company shall, and shall cause each Guarantor to, at their sole cost and
expense, execute and deliver all such agreements and instruments as the Collateral Agent or the Trustee shall reasonably request to more fully or accurately describe the property intended to be Collateral or the obligations intended to be secured by
the Collateral Agreements. The Company shall, and shall cause each Guarantor to, at their sole cost and expense, file any such notice filings or other agreements or instruments as may be reasonably necessary or desirable under applicable law to
perfect the Liens created by the Collateral Agreements at such times and at such places as the Collateral Agent or the Trustee may reasonably request.

recordings and filings of such Mortgage as may be necessary to create a valid, perfected Lien, subject to Permitted Liens, against the properties purported to be covered thereby; 
  
 (2) the Company shall deliver to the Collateral Agent mortgagee’s title insurance policies in favor of
the Collateral Agent, as mortgagee for the ratable benefit of the Collateral Agent, the Trustee and the Holders in an amount equal to 100% of the Fair Market Value of the Premises purported to be covered by the related Mortgage, insuring that title
to such property is marketable and that the interests created by the Mortgage constitute valid Liens thereon free and clear of all Liens, defects and encumbrances other than Permitted Liens, and such policies shall also include, to the extent
available, a revolving credit endorsement and such other endorsements as the Collateral Agent shall reasonably request and shall be accompanied by evidence of the payment in full of all premiums thereon; and 
  
 (3) the Company shall deliver to the Collateral Agent, with
respect to each of the covered Premises, the most recent survey of such Premises, together with either (i) an updated survey certification in favor of the Trustee and the Collateral Agent from the applicable surveyor stating that, based on a visual
inspection of the property and the knowledge of the surveyor, there has been no change in the facts depicted in the survey or (ii) an affidavit from the Company and the Guarantors stating that there has been no change, other than, in each case,
changes that do not materially adversely affect the use by the Company or Guarantor, as applicable, of such Premises for the Company or such Guarantor’s business as so conducted, or intended to be conducted, at such Premises; 
  
 provided, however, that the Company need not comply with its obligations under
this Section 4.17 with respect to the property located at 125 E. Morrow, Sand Springs, Oklahoma until the 60th day following the Issue Date.

the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Excess Cash Flow Offer Payment Date. If only a portion of a Note is purchased pursuant to an Excess Cash Flow Offer, a new
Note in a principal amount equal to the portion thereof not purchased will be issued in the name of the Holder thereof upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be
made). Notes (or portions thereof) purchased pursuant to an Excess Cash Flow Offer will be cancelled and cannot be reissued.

Excess Cash Flow Offer Amount with respect thereto by the aggregate repurchase price of any Notes theretofore repurchased by the Company in the open market (to the extent such amount has not previously reduced any Excess Cash Flow Offer Amount). If
the aggregate repurchase price of Notes tendered pursuant to any Excess Cash Flow Offer is less than the applicable Excess Cash Flow Offer Amount, the Company may, subject to the other provisions of the Indenture, use any such Excess Cash Flow for
any other lawful purpose. 
  
 (f) In each Excess Cash Flow Offer,
the Company will be required to repurchase Notes validly tendered in response to such Excess Cash Flow Offer in accordance with the procedures (including proration in the event of oversubscription) set forth in this Section 4.23. The Company
will not be required to make an Excess Cash Flow Offer relating to any Relevant Fiscal Year if the Excess Cash Flow for such Relevant Fiscal Year is less than $2.0 million. 
  
 (g) Notwithstanding the foregoing, the repurchase of Notes by the Company pursuant to any Excess Cash Flow Offer shall not
be required if it would breach any covenant under the Credit Agreement that prohibits the consummation of the applicable Excess Cash Flow Offer and shall be limited to amounts as provided under the Credit Agreement. 
  
 (h) 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 Notes pursuant to an Excess Cash Flow Offer. To the extent that the provisions of any
securities laws or regulations conflict with this Section 4.23, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.23 by virtue
thereof. 
  
 Section 4.24. Additional
Interest. 
  
 If Additional Interest becomes payable by the
Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an Officers’ Certificate stating (i) the amount of Additional Interest due and payable, (ii) the Section of the Registration Rights Agreement
pursuant to which Additional Interest is due and payable and (iii) the date on which Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives such an Officers’ Certificate, the Trustee may assume without
inquiry that no Additional Interest is payable; provided, that the failure of the Company to deliver to the Trustee such Officers’ Certificate shall not relieve the Company of its obligation to pay any such Additional Interest when due
and payable.

default with respect to Section 5.01 or 10.04, which will constitute an Event of Default with such notice requirement but without such passage of time requirement); 
  
 (4) the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions
thereof) the principal amount of any Indebtedness of the Company or any Restricted Subsidiary of the Company, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured
within 20 days from the date of acceleration) if the aggregate principal amount of such Indebtedness, together 
  

 58 

 with the principal amount of any other such outstanding Indebtedness in default for failure to pay
principal at final maturity or which has been accelerated (in each case with respect to which the 20-day period described above has elapsed), aggregates $5.0 million or more at any time; 
  
 (5) one or more judgments in an aggregate amount in excess of $5.0 million shall have been rendered against

judgment or judgments become final and non-appealable;

for substantially all of its property or (C) orders the winding-up or liquidation of its affairs; and such order or decree shall remain unstayed and in effect for a period of sixty (60) consecutive days; 
  
 (8) any Collateral Agreement at any time for any reason
shall cease to be in full force and effect in all material respects, or ceases to give the Collateral Agent the Liens, rights, powers and privileges purported to be created thereby, superior to and prior to the rights of all third Persons other than
the holders of Permitted Liens and subject to no other Liens except as expressly permitted by the applicable Collateral Agreement; 
  
 (9) the Company or any of the Guarantors, directly or indirectly, contest in any manner the effectiveness, validity, binding nature or

invalid or any Guarantor denies its liability under its Guarantee (other than by reason of release of such Guarantor in accordance with the terms of this Indenture). 
  
 Section 6.02. Acceleration. 
  
 (a) If an Event of Default (other than an Event of Default specified in Section 6.01(6) or (7) above with
respect to the Company) shall occur and be continuing and has not been waived, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of and premium, if any, accrued interest and Additional
Interest, if any, on all the Notes to be due and payable by notice in writing to the Company and the Trustee specifying the Event of Default and that it is a “notice of acceleration” (the “Acceleration Notice”), and the
same shall become immediately due and payable. 
  
 (b) If an Event
of Default specified in Section 6.01(6) or (7) above with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on all of
the outstanding Notes shall ipso facto become and 
  

 59 

 be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 

 
 (c) At any time after a declaration of acceleration with respect to the
Notes as described in Section 6.02(a) and (b), the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences: 
  
 (i) if the rescission would not conflict with any judgment or decree; 
  
 (ii) if all existing Events of Default have been cured or
waived except nonpayment of principal, premium, if any, interest or Additional Interest, if any, that has become due solely because of the acceleration; 
  
 (iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal and
premium, if any, and Additional Interest, if any, which has become due otherwise than by such declaration of acceleration, has been paid; and 
  
 (iv) in the event of the cure or waiver of an Event of Default of the type described in Section 6.01(6) or (7), the Trustee
shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. 
  
 (d) No such rescission shall affect any subsequent Default or impair any right consequent thereto. 
  
 Section 6.03. Other Remedies. 
  
 If an Event of Default occurs and is continuing, each of the Trustee and the
Collateral Agent may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, or interest, or Additional Interest, if any, on the Notes or to enforce the performance of any provision of
the Notes, this Indenture or any Collateral Agreement. 
  
 Each of
the Trustee and the Collateral Agent may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee, the Collateral Agent or any Holder in exercising any
right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent
permitted by law. 
  
 Section 6.04. Waiver of
Past Defaults. 
  
 Subject to Sections 2.09,
6.07 and 9.02, the Holders of a majority in principal amount of the Notes may waive any existing Default or Event of Default and its consequences, except (other than as provided in Section 6.02(c)) a default in the payment of
the principal of or premium, if any, interest or Additional Interest, if any, on any Notes. When a Default or Event of Default is waived, it is cured and ceases to exist. 
  
 Section 6.05. Control by Majority. 
  
 Subject to Section 2.09, the Holders of a majority in principal amount of the outstanding Notes may direct the time,
method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Collateral Agent, as the case may be, or exercising any trust or power conferred on 
  

 60 

 the Trustee or the Collateral Agent, as the case may be, including, without limitation, any remedies provided for in
Section 6.03. Subject to Section 7.01 and 7.02(f), however, the Trustee or the Collateral Agent, as the case may be, may refuse to follow any direction (which direction, if sent to the Trustee or the Collateral Agent, as the
case may be, shall be in writing) that the Trustee or the Collateral Agent, as the case may be, reasonably believes conflicts with any applicable law or this Indenture, that the Trustee or the Collateral Agent, as the case may be, determines may be
unduly prejudicial to the rights of another Holder, or that may subject the Trustee or the Collateral Agent, as the case may be, to personal liability; provided that the Trustee or the Collateral Agent, as the case may be, may take any other
action deemed proper by the Trustee or the Collateral Agent, as the case may be, which is not inconsistent with such direction (which direction, if sent to the Trustee or the Collateral Agent, as the case may be, shall be in writing). 
  
 Section 6.06. Limitation on Suits. 
  
 A Holder may not pursue any remedy with respect to this Indenture or the
Notes unless: 
  
 (1) the Holder gives to the
Trustee written notice of a continuing Event of Default; 
  
 (2) subject to Section 2.09, Holders of at least 25% in principal amount of the outstanding Notes make a written request to the Trustee to institute proceedings in respect of that Event of Default; 

 
 (3) such Holders offer to the Trustee indemnity
reasonably satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request; 
  
 (4) the Trustee does not comply with the request within sixty (60) days after receipt of the request and the offer of indemnity; and

  
 (5) during such sixty (60) day period the
Holders of a majority in principal amount of the outstanding Notes do not give the Trustee a written direction which, in the opinion of the Trustee, is inconsistent with the request. 
  
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over
such other Holder. 
  
 Section 6.07. Rights of
Holders to Receive Payment. 
  
 Notwithstanding any other
provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
  
 Section 6.08. Collection Suit by Trustee or Collateral Agent. 
  
 If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee or the
Collateral Agent may recover judgment (i) in its own name and (ii)(x) in the case of the Trustee, as trustee of an express trust or (y) in the case of the Collateral Agent, as collateral agent on behalf of each of the Secured Parties, in each case
against the Company or any other obligor on the Notes for the whole amount of principal of, premium, if any, and accrued interest, and Additional Interest, if any, remaining unpaid on, the Notes, together with interest on overdue principal and, to
the extent that payment of such interest is lawful, interest on overdue installments of interest at the rate set forth in 
  

 61 

 Section 4.01 and such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel and any other amounts due the Trustee under the Collateral Agreements and Section 7.07.

  
 Section 6.09. Trustee May File Proofs of
Claim. 
  
 The Trustee is authorized to file such proofs of
claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and
the Holders allowed in any judicial proceedings relating to the Company or any other obligor upon the Notes, any of their respective creditors or any of their respective property and shall be entitled and empowered to collect and receive any monies
or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under the Collateral Agreements and Section 7.07. The Company’s payment obligations under this Section 6.09 shall be secured in accordance with the provisions of Section 7.07. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or
to authorize the Trustee or the Collateral Agent, as the case may be, to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 6.10. Priorities. 
  
 If the Trustee collects any money or property pursuant to this Article Six, it shall pay out the money in the following order: 
  
 First: to the Trustee, the Collateral Agent, the Paying Agent and the
Registrar for amounts due under Section 7.07 (including payment of all compensation expense, all liabilities incurred and all advances made by the Trustee or the Collateral Agent, as the case may be, and the costs and expenses of collection);

  
 Second: if the Holders are forced to proceed against the
Company directly without the Trustee or the Collateral Agent, to Holders for their collection costs; 
  
 Third: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any
kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 
  
 Fourth: to the Company or any other obligor on the Notes, as their interests may appear, or as a court of competent jurisdiction may direct. 

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

 62 

 Section 6.11. Undertaking for Costs. 
  
 All parties to this Indenture agree, and each Holder by its acceptance of
its Note shall be deemed to have agreed, that in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the Collateral Agent, as the case may be, for any action taken or omitted by it as
Trustee or the Collateral Agent, as the case may be, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee
or the Collateral Agent, as the case may be, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes. 
  
 Section 6.12. Restoration of Rights and Remedies.

  
 If the Trustee, the Collateral Agent or any Holder has
instituted any proceedings 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, the Collateral Agent, or to such Holder, then and
in every such case, subject to any determination in such proceeding, the Company, the Trustee, the Collateral Agent and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee, the Collateral Agent and the Holders shall continue as though no such proceeding has been instituted.

 The duties and responsibilities of the Trustee shall be as provided by the TIA and as set forth herein. 
  
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such rights and powers vested in it by this Indenture and use the

in case of any such certificates or opinions furnished to the Trustee which by the provisions hereof are furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements
of this Indenture. 
  

 63 

 (c) Notwithstanding anything to the contrary herein contained, the Trustee may not be relieved from

such request, order or direction.

 64 

 (e) The Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond, debenture, or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled, upon reasonable notice to the Company, to examine the books, records and premises of the Company,
personally or by agent or attorney and to consult with the officers and representatives of the Company, including the Company’s accountants and attorneys. Except as expressly stated herein to the contrary, in no event shall the Trustee have any

by an Officer of the Company to have been duly adopted and in full force and effect on the date hereof. 
  
 (h) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless the Trustee
shall have received from the Company, any Guarantor or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 11.02 hereof, and such notice references the Notes and this Indenture.

  
 (i) 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

signed by any persons authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, any Subsidiary of the Company or its respective Affiliates with the same rights it would have if it were
not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11 of this Indenture, and the Trustee is subject to TIA Sections 310(b) and 311.

the Collateral Agreements or any other documents in connection with the issuance of the Notes other than the Trustee’s certificate of authentication, which shall be taken as the statement of Company, and the Trustee assumes no responsibility
for their correctness. 
  
 Beyond the exercise of reasonable care
in the custody thereof and the fulfillment of its obligations under this Indenture, the Intercreditor Agreement and the Collateral Agreements, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or
control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that which it accords its own property. 
  
 The Trustee makes no representations as to and shall not be responsible for the existence, genuineness, value, sufficiency or condition of any of the
Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any Collateral Agreement, or for the validity, perfection, priority or enforceability of the Liens or security interests in any of the Collateral created or
intended to be created by any of the Collateral Agreements, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or
willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral, any Collateral Agreements or any agreement or assignment contained in any thereof, for the validity of the title of the Company or any Guarantor to the
Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral.

written notice from the Company or any Holder, the Trustee shall mail to each Holder, with a copy to the Company, notice of the Default or Event of Default within thirty (30) days thereof. Except in the case of a Default or an Event of Default in
payment of principal of, premium, if any, interest or Additional Interest, if any, on, any Note, including an accelerated payment and the failure to make payment on the Change of Control Payment Date pursuant to a Change of Control Offer and, except
in the case of a failure to comply with Article Five, the Trustee may withhold the notice if and so long as its Board of Directors, the executive committee of its Board of Directors or a committee of its directors and/or Trust Officers in
good faith determines that withholding the notice is in the interest of the Holders. 
  
 Section 7.06. Reports by Trustee to Holders. 
  
 Within sixty (60) days after each May 15, beginning with May 15, 2005, the Trustee shall, to the extent that any of the
events described in TIA Section 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with TIA Section 313(a). The Trustee also shall comply with TIA Sections
313(b) and (c). 
  
 A copy of each report at the time of its
mailing to Holders shall be mailed to the Company and filed by the Company with the SEC and each stock exchange or market, if any, on which the Notes are listed or quoted. 
  
 The Company shall promptly notify the Trustee if the Notes become listed or quoted on any stock exchange or market and the
Trustee shall comply with TIA Section 313(d) and any delisting thereof.

 Section 7.07. Compensation and Indemnity. 
  
 The Company shall pay to the Trustee, Collateral Agent, the Paying Agent and
the Registrar (each an “Indemnified Party”) from time to time compensation for their respective services as Trustee, Collateral Agent, Paying Agent or Registrar, as the case may be, as agreed to between each of the Trustee, the
Collateral Agent, the Paying Agent and the Registrar, on the one hand and the Company, on the other. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse each
Indemnified Party upon request for all reasonable out-of-pocket expenses incurred or made by it in connection with the performance of its duties under, as the case may be, this Indenture or the Collateral Agreements. Such expenses shall include the
reasonable fees and expenses of each of such Indemnified Party’s agents and counsel. 
  
 The Company and the Guarantors, jointly and severally, hereby indemnify each Indemnified Party and its agents, employees, stockholders and directors and officers for, and holds each of them harmless against, any loss,
cost, claim, liability or expense (including taxes) incurred by any of them except for such actions to the extent caused by any gross negligence or willful misconduct on the part of such Indemnified Party, arising out of or in connection with this
Indenture or the Collateral Agreements, or the administration of this trust, including the reasonable costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending themselves against any claim
or liability in connection with the exercise or performance of any of their rights, powers or duties hereunder or thereunder (including the reasonable fees and expenses of counsel). The Trustee shall notify the Company promptly of any claim asserted
against an Indemnified Party for which such Indemnified Party has advised the Trustee that it may seek indemnity hereunder or under the Collateral Agreements. Failure by the Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder. At the Indemnified Party’s sole discretion, the Company shall defend the claim and the Indemnified Party shall cooperate and may participate in the defense; provided that any settlement of a claim shall be approved
in writing by the Indemnified Party. Alternatively, the Indemnified Party may at its option have separate counsel of its own choosing and the Company shall pay the reasonable fees and expenses of such counsel; provided that the Company shall
not be required to pay such fees and expenses if it assumes the Indemnified Party’s defense and there is no conflict of interest between the Company and the Indemnified Party in connection with such defense as reasonably determined by the
Indemnified Party. The Company need not pay for any settlement made without its written consent, which consent shall not be unreasonably withheld. 
  
 To secure the Company’s and each Guarantor’s payment obligations in this Section 7.07, each Indemnified Party shall have a lien prior to
the Notes on all Collateral held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or interest on particular Notes which have been called for redemption. 
  
 When an Indemnified Party incurs expenses or renders services after an Event
of Default specified in Section 6.01(6) or (7) occurs, such expenses (including the reasonable fees and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under any
Bankruptcy Code. 
  
 The obligations of the Company under this
Section 7.07 shall survive the satisfaction and discharge of this Indenture, termination of the Collateral Agreements or the resignation or removal of the Trustee. 
  
 The Trustee shall comply with the provisions of TIA Section 312(b)(2) to the extent applicable. 
  

 67 

 Section 7.08. Replacement of Trustee. 
  
 The Trustee may resign by so notifying the Company. The Holders of a
majority in aggregate principal amount of the outstanding Notes may remove the Trustee by so notifying the Company and the Trustee in writing and may appoint a successor Trustee. The Company, by a Board Resolution, may remove the Trustee if:

  
 (1) the Trustee fails to comply with
Section 7.10; 
  
 (2) the Trustee is
adjudged bankrupt or insolvent; 
  
 (3) a
receiver or other public officer takes charge of the Trustee or its property; or 
  
 (4) the Trustee becomes incapable of acting with respect to the Notes. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall
notify each Holder in writing of such event and shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company 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 rights, powers, trusts, duties and obligations of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such Trustee so ceasing to act hereunder subject nevertheless to its lien, if any, provided for in Section 7.07. Upon request of the Company or the successor Trustee, such retiring Trustee shall at the expense of the Company
and upon payment of the charges of the Trustee then unpaid, 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. 
  
 If a successor Trustee does not take office within thirty (30) days after the retiring Trustee resigns or is removed, the retiring Trustee, at the Company’s expense, the Company or the Holders of at least 10% in
principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 If the Trustee fails to comply with Section 7.10, any Holder who satisfies the requirements of TIA Section 310(b) may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 The Company shall give notice of any resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders in writing.
Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office and its notice address for purposes of Section 11.02. 
  
 Notwithstanding any resignation or replacement of the Trustee pursuant to this Section 7.08, the Company’s
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

 Section 7.09. Successor Trustee by Merger, Etc. 
  
 If the Trustee consolidates with, merges or converts into, or transfers all
or substantially all of its corporate trust business (including the administration of the trust created by this Indenture) to, another Person, the resulting, surviving or transferee Person without any further act shall, if such resulting, surviving
or transferee Person is otherwise eligible hereunder, be the successor Trustee; provided, however, that such Person shall be otherwise qualified and eligible under this Article Seven. 
  
 In case any Notes have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such
Notes. 
  
 Section 7.10. Eligibility;
Disqualification. 
  
 (a) This Indenture shall always have a
Trustee who satisfies the requirements of TIA Sections 310(a)(1), (2), (3) and (5). The Trustee (or, in the case of a corporation included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus
of at least $50,000,000 as set forth in its most recent published annual report of condition. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet
the capital requirements of TIA Section 310(a)(2). The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which
other securities, or certificates of interest or participation in other securities, of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. The provisions of TIA Section 310 shall apply to
the Company, as obligor of the Notes. 
  
 (b) If the Trustee has
or acquires a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. 
  
 Section 7.11. Preferential Collection of Claims Against
Company. 
  
 The Trustee shall comply with TIA Section
311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
  
 Section 7.12. Trustee as Paying Agent and Collateral
Agent. 
  
 References to the Trustee in Sections
7.01(f), 7.02, 7.03, 7.04, and 7.07 shall include the Trustee in its role as Paying Agent and as Collateral Agent. 
  
 Section 7.13. Co-Trustees , Co-Collateral Agent and Separate Trustees and Collateral Agent. 
  
 (a) At any time or times, for the purpose of meeting the legal requirements
of any jurisdiction in which any of the Collateral may at the time be located, the Company, the Trustee and the Collateral Agent shall have the power to appoint, and, upon the written request of the Trustee, the Collateral Agent or of the Holders of
at least 25% in principal amount of the Notes outstanding, the Company shall for such purpose, join with the Trustee or the Collateral Agent, as the case may be, in the execution, delivery and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons approved by the Trustee either to act as co-trustee, jointly with the Trustee, of all or 
  

 69 

 any part of the Collateral, to act as co-collateral agent, jointly with the Collateral Agent, or to act as separate
trustees or Collateral Agent of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons in the capacity aforesaid, any property, title, right or power, deemed
necessary or desirable, subject to the other provisions of this Section 7.13. 
  
 (b) Should any written instrument from the Company be required by any co-trustee, co-collateral agent or separate trustee or separate collateral agent so appointed for more fully confirming to such co-trustee or
separate trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company. 
  

(c) Every co-trustee, co-collateral agent or separate trustee or separate collateral agent shall, to the extent permitted by law, but to such extent
only, be appointed subject to the following terms, namely: 
  
 (i) The Notes shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be

exercised or performed by the Trustee or by the Trustee and such co-trustee or separate trustee, or by the Collateral Agent and such co-collateral agent or separate collateral agent, jointly as shall be provided in the instrument appointing such
co-trustee or separate trustee or co-collateral agent or separate collateral agent, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Trustee shall be incompetent or unqualified to
perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee, collateral agent or co-collateral agent or separate collateral agent. 
  
 (iii) The Trustee at any time, by an instrument in writing
executed by it, with the concurrence of the Company evidenced by a Board Resolution, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section 7.13, and, in case an Event of Default has occurred
and is continuing, the Trustee shall have power to accept the resignation of, or remove, any such co-trustee, co-collateral agent, separate trustee or separate collateral agent without the concurrence of the Company. Upon the written request of the
Trustee, the Company shall join with the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee, co-collateral agent, separate
trustee or separate collateral agent so resigned or removed may be appointed in the manner provided in this Section 7.13. 
  
 (iv) No co-trustee, co-collateral agent or separate trustee or separate collateral agent hereunder shall be personally liable by reason of
any act or omission of the Trustee or any other such trustee or collateral agent hereunder.

 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 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, or representation 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 or representation by counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows that the certificate or opinion or representations with
respect to such matters are erroneous. 
  
 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.

 SATISFACTION AND DISCHARGE OF INDENTURE 
  
 Section 8.01. Legal Defeasance and Covenant
Defeasance. 
  
 (a) The Company may, at its option and at any
time, elect to have either paragraph (b) or paragraph (c) below be applied to the outstanding Notes upon compliance with the applicable conditions set forth in paragraph (d). 
  
 (b) Upon the Company’s exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company and the Guarantors shall be deemed to have been released and discharged from their obligations with respect to the outstanding Notes, the Guarantees and the Collateral Agreements on the date the
applicable conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by
the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of the Sections and matters under this Indenture referred to in clause (i) and (ii) below, and the Company and the
Guarantors shall be deemed to have satisfied all their other obligations under such Notes and this Indenture, the Guarantees and the Collateral Agreements, except for the following which shall survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in paragraph (d) below and as more fully set forth in such paragraph payments in respect of the principal of, and premium, if any,
interest and Additional Interest, if any, on such Notes when such payments are due, (ii) obligations listed in Section 8.03, subject to compliance with this Section 8.01 and (iii) the rights, powers, trusts, duties and immunities of
the Trustee and the Company’s obligations in connection therewith. The Company may exercise its option under this paragraph (b) notwithstanding the prior exercise of its option under paragraph (c) below with respect to the Notes.

  

 71 

 (c) Upon the Company’s exercise under paragraph (a) of the option applicable to this
paragraph (c), the Company and its Restricted Subsidiaries shall be released and discharged from their obligations under any covenant contained in Section 4.05, Sections 4.08 through 4.20, Sections 4.22 through
4.24 and Section 5.01(2), with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed to be
not “outstanding” for the purpose of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all
other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby. In addition, upon the Company’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in paragraph (d)
below, Sections 6.01(3) through 6.01(10) (except, in the case of Section 6.01(6) and 6.01(7), with respect only to Significant Subsidiaries) shall not constitute Events of Default. 
  
 (d) The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Notes: 
  
 (1) The Company shall have irrevocably deposited in trust with the Trustee, pursuant to an irrevocable trust and security agreement in form and substance reasonably satisfactory to the Trustee, U.S. Legal Tender or
non-callable U.S. Government Obligations or a combination thereof, in such amounts and at such times as are sufficient, in the opinion of a nationally-recognized firm of independent public accountants, to pay the principal of, and premium, if any,
interest and Additional Interest, if any, on the outstanding Notes on the stated dates for payment or redemption, as the case may be; provided, however, that the Trustee (or other qualifying trustee) shall have received an irrevocable
written order from the Company instructing the Trustee (or other qualifying trustee) to apply such U.S. Legal Tender or the proceeds of such U.S. Government Obligations to said payments with respect to the Notes to maturity or redemption;

  
 (2) 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 arising in connection with the substantially contemporaneous borrowing of funds to fund the deposit referenced in clause (1) above and the granting of
any Lien securing such borrowing) or insofar as Defaults or Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of such deposit; 
  
 (3) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default hereunder (other
than a Default or Event of Default arising in connection with the substantially contemporaneous borrowing of funds to fund the deposit referenced in clause (1) above and the granting of any Lien securing such borrowing) or any other material
agreement or instrument to which the Company or any of it Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
  
 (4) (i) In the event the Company elects paragraph (b) above, the Company shall deliver to the Trustee an Opinion of Counsel in the
United States of America, in form and substance reasonably satisfactory to the Trustee, to the effect that (A) the Company has received 
  

 72 

 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 state that, Holders shall not recognize income, gain or loss for federal income tax purposes as a
result of such Legal Defeasance contemplated hereby and shall be subject to federal income tax in 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 or (ii) in the event
the Company elects paragraph (c) above, the Company shall deliver to the Trustee an Opinion of Counsel in the United States, in form and substance reasonably satisfactory to the Trustee, to the effect that Holders shall not recognize income,
gain or loss for federal income tax purposes as a result of such Covenant Defeasance contemplated hereby and shall be subject to federal income tax in 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; 
  
 (5) The
Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit under clause (1) was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the
intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; 
  
 (6) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent specified herein relating to the defeasance contemplated by this Section 8.01 have been complied with; and 
  
 (7) The Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary qualifications and exclusions) to the
effect that after the 91st day following the date of deposit, the trust funds will not be subject to the effect of
any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally. 
  
 Notwithstanding the foregoing, the Opinion of Counsel required by Section 8.01(d)(4)(i) above with respect to a Legal Defeasance need not be delivered if all Notes
not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) shall become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company. 
  
 In the event all or any portion of the Notes are to be redeemed through such irrevocable trust, the Company must make arrangements reasonably satisfactory to the Trustee, at the time of such deposit, for the giving of the notice of such
redemption or redemptions by the Trustee in the name and at the expense of the Company. 
  
 Section 8.02. Satisfaction and Discharge. 
  

In addition to the Company’s rights under Section 8.01, the Company may terminate all of its obligations under this Indenture (subject to
Section 8.03), and this Indenture, the Notes, the Guarantees and the Collateral Agreements, and all Liens created thereunder, shall be discharged and shall cease to be in effect when: 
  
 (1) either: 
  
 (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or paid as provided in Section 2.07 and Notes for whose payment money has theretofore been deposited in trust or segregated 
  

 73 

 and held in trust by the Company and thereafter repaid to the Company or discharged from such trust)
have been delivered to the Trustee for cancellation; or 
  
 (b) all Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable, (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 reasonably satisfactory to the Trustee, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on
the Notes not theretofore delivered to the Trustee for cancellation, for principal of, and premium, if any, interest and Additional Interest, if any, on the Notes to the date of deposit together with irrevocable instructions from the Company
directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; 
  
 (2) all other sums payable under this Indenture by the Company have been paid; and 
  
 (3) the Company has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with. 
  
 Section 8.03. Survival of Certain Obligations.

  
 Notwithstanding the satisfaction and discharge of this
Indenture and of the Notes referred to in Section 8.01 or 8.02, the respective obligations of the Company and the Trustee under Sections 2.03, 2.04, 2.05, 2.06, 2.07 and 2.08,
Sections 7.07 and 7.08 and Sections 8.05, 8.06 and 8.07 shall survive until the Notes are no longer outstanding, and thereafter the obligations of the Company and the Trustee under Sections 7.07,
8.04, 8.05 and 8.06 and 8.07 shall survive. 
  
 Section 8.04. Acknowledgment of Discharge by Trustee. 
  
 Subject to Section 8.07, after (i) the conditions of Section 8.01 or 8.02 have been satisfied, (ii) the Company has paid or caused to be paid all other sums payable hereunder by the Company and
(iii) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent referred to in clause (i) above relating to the satisfaction and discharge of this Indenture
have been complied with, the Trustee, upon written request, shall acknowledge in writing the discharge of the Company’s obligations under this Indenture except for those surviving obligations specified in Section 8.03 and the Trustee
shall execute and deliver to the Company any document reasonably requested by the Company to effect or evidence any release and discharge of Lien or Collateral Agreement contemplated by Section 12.05. 
  
 Section 8.05. Application of Trust Moneys. 

 
 The Trustee shall hold any U.S. Legal Tender or U.S. Government
Obligations deposited with it in the irrevocable trust established pursuant to Section 8.01. The Trustee shall apply the deposited U.S. Legal Tender or the U.S. Government obligations, together with earnings thereon, through the Paying Agent,
in accordance with this Indenture and the terms of the irrevocable trust agreement established pursuant to Section 8.01, to the payment of principal of, premium, if any, and interest, and Additional Interest, if any, on the Notes. Anything in
this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s request any U.S. Legal Tender or U.S. Government Obligations held by it as provided in Section
8.01(d) which, in the opinion of a nationally-recognized firm of independent public accountants expressed in a written certification thereof 
  

 74 

 delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance. 
  
 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 8.01 or 8.02 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 outstanding Notes. 
  
 Section 8.06. Repayment to the Company; Unclaimed Money. 
  
 Subject to Sections 7.07, 8.01 and 8.02, the Trustee and the Paying Agent shall promptly pay to the
Company upon written request from the Company any excess U.S. Legal Tender or U.S. Government Obligations held by them at any time. The Trustee and the Paying Agent shall pay to the Company, upon receipt by the Trustee or the Paying Agent, as the
case may be, of a written request from the Company any money held by it for the payment of principal, premium, if any, or interest and Additional Interest, if any, that remains unclaimed for two years after payment to the Holders is required,
without interest thereon; provided, however, that the Trustee and the Paying Agent before being required to make any payment may, but need not, at the expense of the Company cause to be published once in a newspaper of general
circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least thirty (30) days from the date of such publication or
mailing, any unclaimed balance of such money then remaining shall be repaid to the Company, without interest thereon. After payment to the Company, Holders entitled to money must look solely to the Company for payment as general creditors unless an
applicable abandoned property law designated another Person, and all liability of the Trustee or Paying Agent with respect to such money shall thereupon cease. 
  

Section 8.07. Reinstatement. 
  
 If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.01 or
8.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and each Guarantors’ obligations
under this Indenture and each other Indenture Document to which such person is a party shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 or 8.02 until such time as the Trustee or Paying Agent is
permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.01 or 8.02; provided, however, that if the Company has made any payment of premium, if any, or interest and
Additional Interest, if any, on or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

 (3) to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders in accordance with Section

provided, however, that (a) compliance with this Indenture as so amended would not result in the Notes being transferred in violation of the Securities Act or any other applicable securities law and (b) such amendment does not
materially affect the rights of Holders to transfer the Notes, 
  
 so long as such
amendment, modification, waiver or supplement does not, in the opinion of the Trustee and, if such amendment, modification or supplement relates to any Collateral Agreement or the Intercreditor Agreement, the Collateral Agent, adversely affect the
rights of any of the Holders in any material respect. In formulating its opinion on such matters, each of the Trustee and, if such amendment, modification, waiver or supplement relates to any Collateral Agreement or the Intercreditor Agreement, the

 Section
9.02. With Consent of Holders. 
  
 The Company and the
Guarantors, when authorized by a Board Resolution, and the Trustee, or the Collateral Agent, as applicable, together, with the written consent of the Holder or Holders of at least a majority in aggregate principal amount of the outstanding Notes,
may amend or supplement this Indenture, the Notes, any Collateral Agreement, the Guarantees or the Intercreditor Agreement without notice to any other Holders. The Holder or Holders of a majority in aggregate principal amount of the 
  

 76 

 outstanding Notes may waive compliance by the Company with any provision of this Indenture, any Collateral Agreement, the
Notes, or the Intercreditor Agreement without notice to any other Holder. However, no amendment, supplement or waiver, including a waiver pursuant to Section 6.04, shall without the consent of each Holder of each Note affected thereby:

  
 (1) reduce the principal amount of Notes
whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Notes; 
  
 (2) reduce the rate of or change or have the effect of changing the time for payment of interest, including default interest, or

provisions of this Indenture protecting the right of each Holder to receive payment of principal of, premium, if any, interest and Additional Interest, if any, on such Note on or after the due date thereof or to bring suit to enforce such payment,
or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of Default; 
  
 (6) amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer after
the occurrence of a Change of Control, make and consummate an Excess Cash Flow Offer with respect to any fiscal year of the Company (or portion thereof) following the ending thereof, or make and consummate a Net Proceeds Offer with respect to any
Asset Sale that has been consummated or, modify any of the provisions or definitions with respect thereto; 
  
 (7) modify or change any provision of this Indenture or the related definitions affecting the ranking of the Notes or any Guarantee or any

Indenture otherwise than in accordance with the terms of this Indenture; 
  
 (9) release all or substantially all of the Collateral otherwise than in accordance with the terms of this Indenture and the Collateral Agreements; or 
  
 (10) make any change to Section 9.01 or this Section 9.02. 
  
 It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the
Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver. 
  
 Section 9.03.
Compliance with TIA. 
  
 Every amendment, waiver or
supplement of this Indenture, the Notes, the Collateral Agreements, the Guarantees or the Intercreditor Agreement shall comply with the TIA as then in effect. 
  

Section 9.04. Revocation and Effect of Consents. 
  
 Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the
Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. Subject to the following paragraph, any such Holder or
subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by written notice to the Trustee and the Company received before the date on which the Trustee and if such amendment, waiver or supplement relates to any
Collateral Agreement or the Intercreditor Agreement, the Collateral Agent, receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the
amendment, supplement or waiver. An amendment, waiver or supplement shall become effective upon receipt by the Trustee or the Collateral Agent, as the case may be, of written consents from the Holders of the requisite percentage in principal amount
of the outstanding Notes or such Officers’ Certificate, whichever first occurs, and the execution thereof by the Trustee or the Collateral Agent, as the case may be. 
  
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to
consent to any amendment, supplement or waiver, which record date shall be either (i) at least thirty (30) days prior to the first solicitation of such consent or (ii) the date of the most recent list furnished to the Trustee under Section
2.05. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to
revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than ninety (90) days after such record date. 
  
 After an amendment, supplement or waiver becomes effective, it shall bind
every Holder unless it makes a change described in any of clauses (1) through (10) of Section 9.02, in which case, the 
  

 78 

 amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder
of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of, premium, if any, and
interest and Additional Interest, if any, on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder.

  
 Section 9.05. Notation on or Exchange of
Notes. 
  
 If an amendment, supplement or waiver changes the
terms of a Note, the Trustee may require the Holder of the Note to deliver the Note to the Trustee. The Trustee at the written direction of the Company may place an appropriate notation on the Note about the changed terms and return it to the Holder
and the Trustee may place an appropriate notation on any Note thereafter authenticated. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that
reflects the changed terms. Failure to make an appropriate notation, or issue a new Note, shall not affect the validity and effect of such amendment, supplement or waiver. Any such notation or exchange shall be made at the sole cost and expense of
the Company. Failure to make the appropriate notation or issue a new Note shall not effect the validity and effect of such amendment, supplement or waiver. 
  
 Section 9.06. Trustee to Sign Amendments, Etc. 
  
 The Trustee and/or the Collateral Agent, as applicable, shall execute any amendment, supplement or waiver authorized
pursuant to this Article Nine; provided that the Trustee or the Collateral Agent, as the case may be, may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the rights, duties or immunities
of the Trustee or the Collateral Agent, as the case may be, under this Indenture, any Collateral Agreement or the Intercreditor Agreement. The Trustee or the Collateral Agent, as the case may be, shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture.
Such Opinion of Counsel shall not be an expense of the Trustee or the Collateral Agent, as the case may be, and shall be paid for by the Company. 
  
 Section 9.07. Conformity with Trust Indenture Act. 
  
 Every supplemental indenture executed pursuant to this Article Nine shall conform to the requirements of the TIA as
then in effect. 
  
 ARTICLE TEN 
  
 GUARANTEE 
  
 Section 10.01. Guarantee. 
  
 Each Guarantor hereby fully, irrevocably and unconditionally, jointly and
severally, unconditionally and irrevocably guarantees (such guarantee to be referred to herein as the “Guarantee”), to each of the Holders, the Trustee and the Collateral Agent and its respective successors and assigns that (i) the
principal of, premium, if any and interest, and Additional Interest, if any, on the Notes shall be promptly paid in full when due, subject to any applicable grace period, whether upon redemption pursuant to the terms of the Notes, by acceleration or
otherwise, and interest on the overdue principal, if any, and 
  

 79 

 interest on any interest, if any, to the extent lawful, of the Notes and all other obligations of the Company to the
Holders, the Trustee and the Collateral Agent hereunder, thereunder or under any Collateral Agreement shall be promptly paid in full or performed, all in accordance with the terms hereof, thereof and of the Collateral Agreements; and (ii) in case of
any extension of time of payment or renewal of any of the Notes or of any 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, subject to any applicable grace
period, whether at stated maturity, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 10.03. The Guarantee of each Guarantor shall rank senior in
right of payment to all subordinated Indebtedness of such Guarantor and equal in right of payment with all other senior obligations of such Guarantor. Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective
of the validity, regularity or enforceability of the Notes, this Indenture or any Collateral Agreement, the absence of any action to enforce the same, any waiver or consent by any of the Holders with respect to any provisions hereof or thereof, any
release of any other Guarantor, the recovery 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 diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and in this Guarantee. The obligations of each Guarantor are limited to the maximum amount which,
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
its Guarantee or pursuant to its contribution obligations under this Indenture, shall result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. The net
worth of any Guarantor for such purpose shall include any claim of such Guarantor against the Company for reimbursement and any claim against any other Guarantor for contribution. Each Guarantor may consolidate with or merge into or sell its assets
to the Company or another Guarantor without limitation in accordance with Sections 5.01, 4.10 and 10.04. If any Holder, the Collateral Agent or the Trustee is required by any court or otherwise to return to the Company, any
Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee, the Collateral Agent or such Holder, this Guarantee, to
the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders, the Collateral Agent and the Trustee, on the other hand, (x) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose
of this Guarantee. 
  
 Section 10.02. Release
of a Guarantor. 
  
 A Guarantor will be automatically and
unconditionally released from its Guarantee (and may subsequently dissolve) without any action required on the part of the Trustee or any Holder: 
  
 (1) if (a) all of the Capital Stock issued by such Guarantor or all or substantially all of the assets of such Guarantor are sold or
otherwise disposed of (including by way of merger or consolidation) to a Person other than the Company or any of its Domestic Restricted Subsidiaries or (b) such Guarantor ceases to be a Restricted Subsidiary, and the Company otherwise complies, to
the extent applicable, with Section 4.10, or 
  

 80 

 (2) if the Company designates such Guarantor as an Unrestricted Subsidiary in accordance
with Section 4.09, or 
  
 (3) if the
Company exercises its legal defeasance option or its covenant defeasance option as described in Section 8.01, or 
  
 (4) upon satisfaction and discharge of this Indenture or payment in full of the principal of, premium, if any, accrued and unpaid interest
and Additional Interest, if any, on the Notes and all other Obligations that are then due and payable. 
  
 The Trustee shall promptly deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an
Officers’ Certificate certifying as to the compliance with this Section 10.02. Any Guarantor not so released remains liable for the full amount of its Guarantee as provided in this Article Ten. 
  
 Section 10.03. Limitation of Guarantor’s
Liability. 
  
 Each Guarantor and, by its acceptance hereof,
each of the Holders hereby confirms that it is the intention of all such parties that the guarantee by such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Code, 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 the
Guarantee 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 its Guarantee or pursuant to Section 10.05, result in the obligations of such Guarantor under the Guarantee not constituting such fraudulent transfer or conveyance. 
  
 Section 10.04. Guarantors May Consolidate, etc., on
Certain Terms. 
  
 Each Guarantor (other than any Guarantor
whose Guarantee is to be released in accordance with the terms of the Guarantee and this Indenture in connection with any transaction complying with Section 4.10) will not, and the Company will not cause or permit any Guarantor to,
consolidate with or merge with or into any Person other than the Company or any other Guarantor unless: 
  
 (1) the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease,
conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia; 
  
 (2) such entity assumes (a) by supplemental indenture (in form and substance reasonably satisfactory to the
Trustee), executed and delivered to the Trustee, all of the obligations of the Guarantor under the Guarantee and the performance of every covenant of the Guarantee, this Indenture and the Registration Rights Agreement and (b) by amendment,
supplement or other instrument (in form and substance satisfactory to the Trustee and the Collateral Agent) executed and delivered to the Trustee and the Collateral Agent, all obligations of the Guarantor under the Collateral Agreements and in
connection therewith shall cause such instruments to be filed and recorded in such jurisdictions and take such other actions as may be required by applicable law to perfect or continue the perfection of the Lien created under the Collateral
Agreements on the Collateral owned by or transferred to the surviving entity; and 
  

 81 

 (3) immediately after giving effect to such transaction, no Default or Event of Default
shall have occurred and be continuing. 
  
 Any merger or
consolidation of (i) a Guarantor with and into the Company (with the Company being the surviving entity) or another Guarantor (other than the Railway Subsidiary) or (ii) a Guarantor or the Company with an Affiliate organized solely for the purpose
of reincorporating such Guarantor or the Company in another jurisdiction in the United States or any state thereof or the District of Columbia need only comply with (A) in the case of a merger or consolidation described in clause (ii),
clause (4) of Section 5.01; and (B) (x) clause (1)(b)(y) of Section 5.01 and (y) clause (2) above. 
  
 Section 10.05. Contribution. 
  
 In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that each Guarantor that makes a payment or
distribution under a Guarantee shall be entitled to a pro rata contribution from each other Guarantor hereunder based on the net assets of each other Guarantor. The preceding sentence shall in no way affect the rights of the Holders of
Notes to the benefits of this Indenture, the Notes or the Guarantees. 
  
 Section 10.06. Waiver of Subrogation. 
  
 Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby.

  
 Section 10.07. Waiver of Stay, Extension or
Usury Laws. 
  
 Each Guarantor covenants to the extent
permitted by law that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive such Guarantor from
performing its Guarantee as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Guarantee; and each Guarantor hereby expressly waives to the extent permitted by
law 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.

 (REVERSE OF NOTE) 
  
 11 3/8% Senior Secured Note due 2011 
  

	 	1.	Interest. 

  
 Sheffield Steel Corporation (the ”Company”, which term includes any Surviving Entity) promises to pay interest on the principal amount
of this Note at the rate per annum shown above. Interest on the Note will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from and including the date of issuance. The Company will pay interest
semi-annually in arrears on each Interest Payment Date, commencing February 15, 2005. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. [FOR REGULATION S TEMPORARY GLOBAL NOTES INSERT: Until this Regulation
S Temporary Global Note is exchanged for one or more Regulation S Permanent Global Notes, the Holder hereof shall not be entitled to receive payments of interest hereon; until so exchanged in full, this Regulation S Temporary Global Note shall in
all other respects be entitled to the same benefits as other Notes under the Indenture]. 
  

	 	2.	Method of Payment. 

  
 The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the
Record Date immediately preceding the Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date, and on or before such Interest Payment Date. Holders must surrender Notes to
a Paying Agent to collect principal payments. The Company shall 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 (“U.S. Legal Tender”).
However, the Company may pay principal and interest by check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder’s registered address. 
  

	 	3.	Paying Agent and Registrar. 

  
 Initially, U.S. Bank National Association (the “Trustee”) will act as Paying Agent and Registrar. The Company may change any Paying
Agent, Registrar or co-Registrar without notice to the Holders. Neither the Company nor any Affiliate of the Company shall act as Paying Agent or Registrar. 
  

	 	4.	Indenture. 

  
 The Notes and the Guarantees were issued under an Indenture, dated as of August 12, 2004 (the “Indenture”), among the Company, the
Guarantors named therein and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the
“TIA”), as in effect on the date of the Indenture until such time as the Indenture is qualified 
  

 A-4 

 under the TIA, and thereafter as in effect on the date on which the Indenture is qualified under the TIA. Notwithstanding
anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of such terms. The Notes are senior secured obligations of the Company. Each Holder, by
accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. 
  

	 	5.	Redemption. 

  
 (b) Optional Redemption prior to August 15, 2008. At any time prior to August 15, 2008, the Company may, at its option, redeem the Notes, in whole
or in part, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to the greater of: 
  
 (1) 100% of the aggregate principal amount of the Notes being redeemed; and 
  
 (2) the sum of the present values of 105.688% of the aggregate principal amount of such Notes and scheduled
payments of interest on such Notes to and including August 15, 2008, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, together with, in
each case, accrued and unpaid interest and Additional Interest, if any, to the Redemption Date (subject to the right of the right of holders of record on the relevant record date to received interest due on the relevant Interest Payment Date).

  
 Any such redemption, purchase or notice pursuant to this
Section 5(a) may, at the Company’s discretion, be subject to satisfaction of one or more conditions precedent, including but not limited to the occurrence of a Change of Control. 
  
 (c) Optional Redemption on or after August 15, 2008. Except as described in Section 5(a) and (c), the Notes are not
redeemable before August 15, 2008. Thereafter, the Company may on any one or more occasions redeem the Notes. The Notes will be redeemed at their option, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following
redemption prices (expressed as percentages of the aggregate principal amount thereof) if redeemed during the twelve-month period commencing on August 15 of the year set forth below: 
  

				
	 Year

	  	Percentage

	 
	 2008
	  	105.688	%

 In addition, the Company must pay accrued and unpaid interest and Additional Interest, if any, on the
aggregate principal amount of the Notes redeemed to (but not including) the Redemption Date. 
  
 (d) Optional Redemption upon Equity Offerings. At any time, or from time to time, on or prior to August 15, 2007, the Company may, at its option, use an amount not to exceed the net cash proceeds of one or more
Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes ever issued under this Indenture. The Notes will be redeemed at a redemption price of 111.375% of the aggregate principal amount thereof, plus accrued and unpaid
interest and Additional Interest, if any, to the date of redemption, provided that: 
  
 (1) at least 65% of the original principal amount of Notes ever issued under this Indenture remains outstanding immediately after any such
redemption; and 
  
 (2) the Company makes such
redemption not more than 120 days after the consummation of any such Equity Offering. 
  
 (e) Notice of Redemption. Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such
Holder’s registered address. If fewer than all of the Notes are to be redeemed, at any time, selection of Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if
any, on which the Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee deems to be fair and appropriate; provided that no partial redemption will reduce the principal amount of a
Note not redeemed to a denomination of less than $1,000; and provided, further, that any such partial redemption made with the proceeds of an Equity Offering will be made only on a pro rata basis or on as nearly a pro rata basis as
practicable (subject to the procedures of the DTC or any other depository) unless such method is otherwise prohibited. Notes in denominations of $1,000 or more may be redeemed in part. 
  
 Any notice of redemption under Section 5(a) may provide that payment of the price and performance of the Company’s
obligations with respect to such redemption or purchase may be performed by any other Person. 
  
 Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for redemption on such redemption date sufficient to pay such
redemption price plus accrued and unpaid interest and Additional Interest, if any, to (but not including) the Redemption Date, the Notes called for redemption will cease to bear interest from and after such redemption date, and the only remaining
right of the Holders of such Notes will be to receive payment of the redemption price plus accrued and unpaid interest and Additional Interest, if any, as of the redemption date upon surrender to the Paying Agent of the Notes redeemed. 

 

	 	6.	Offers to Purchase. 

  
 Sections 4.10, 4.22 and 4.23 of the Indenture provide that after certain Asset Sales, upon the occurrence of a Change of Control and upon the Company
having Excess Cash Flow and subject to further limitations contained therein, the Company will make an offer 
  

 A-6 

 to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 
  

	 	7.	Registration Rights. 

  
 Pursuant to the Registration Rights Agreement among the Company, the Guarantors and the Initial Purchaser of the Initial Notes, the Company will be
obligated to consummate an exchange offer. Upon such exchange offering, the Holders of the Initial Notes shall have the right, subject to compliance with securities laws, to exchange such Initial Notes for 11 3/8% Senior Secured Exchange Notes due 2011, which have been registered under the Securities Act, in like principal
amount and having terms identical in all material respects to the Initial Notes. The Holders of the Initial Notes shall be entitled to receive certain additional interest payments in the event such exchange offer is not consummated and upon certain
other conditions, all pursuant to and in accordance with the terms of the Registration Rights Agreement. 
  

	 	8.	Denominations; Transfer; Exchange. 

  
 The Notes are in registered form, without coupons, in denominations of $1,000 and integral multiples thereof. A Holder shall register the transfer of or
exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes, fees or similar governmental charges payable in connection
therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption. 
  

	 	9.	Persons Deemed Owners. 

  
 The registered Holder of a Note shall be treated as the owner of it and the Notes of which it is composed for all purposes. 
  

	 	10.	Unclaimed Money. 

  
 If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent may pay the money without interest
thereon back to the Company. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 
  

	 	11.	Discharge Prior to Redemption or Maturity. 

  
 If the Company at any time deposits with the Trustee U.S. Legal Tender or U.S. Government Obligations sufficient to pay the principal of and interest on
the Notes to redemption or Maturity and complies with the other provisions of the Indenture relating thereto, the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, except for the rights
of Holders to receive payments in respect of the principal of, and premium, if any, interest and Additional Interest, if any, on the Notes when such payments are due from the deposits referred to above. 
  

 A-7 

	 	12.	Amendment; Supplement; Waiver. 

  
 Subject to certain exceptions, the Indenture, the Notes or the Guarantees may be amended or supplemented with the written consent of the Holders of at
least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or Event of Default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal
amount of the Notes then outstanding. Without consent of any Holder, the parties thereto may amend or supplement the Indenture, the Notes or the Guarantees to, among other things, cure any ambiguity, defect or inconsistency, provide for
uncertificated Notes or Guarantees in addition to or in place of certificated Notes or Guarantees, comply with the TIA, or comply with Article Five or Section 10.04 of the Indenture or make any other change that does not adversely affect in any
material respect the rights of any Holder of a Note.

Person, sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets or adopt a plan of liquidation. Such limitations are subject to a number of important qualifications and exceptions. The Company must
annually report to the Trustee on compliance with such limitations. 
  

	 	14.	Successors. 

  
 When a successor assumes, in accordance with the Indenture, all the obligations of its predecessor under the Notes, the Guarantees and the Indenture, the
predecessor will be released from those obligations. 
  

	 	15.	Defaults and Remedies. 

  
 If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding
may declare all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture except as provided in the Indenture. The Trustee is not obligated to enforce the
Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in
their interest.

	 	18.	Guarantees. 

  
 Payment of principal and interest and Additional Interest, if any (including interest on overdue principal and overdue interest, if lawful), is
unconditionally guaranteed, jointly and severally, by each of the Guarantors.

 (REVERSE OF NOTE) 
  
 11 3/8% Senior Secured Note due 2011 
  

	 	1.	Interest. 

  
 Sheffield Steel Corporation (the ”Company”, which term includes any Surviving Entity) promises to pay interest on the principal amount
of this Note at the rate per annum shown above. Interest on the Note will accrue (a) from the later of (i) the last interest payment date on which interest was paid on the note surrendered in exchange for this Note (the “Surrendered
Note”), or (ii) if the Surrendered Note is surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the
date of such interest payment date; or (b) if no interest has been paid on such Surrendered Note, from the Issue Date. The Company will pay interest semi-annually in arrears on each Interest Payment Date, commencing August 15, 2005. Interest will be
computed on the basis of a 360-day year comprised of twelve 30-day months. 
  

	 	2.	Method of Payment. 

  
 The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the
Record Date immediately preceding the Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date, and on or before such Interest Payment Date. Holders must surrender Notes to
a Paying Agent to collect principal payments. The Company shall 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 (“U.S. Legal Tender”).
However, the Company may pay principal and interest by check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the Paying Agent or to a Holder at the Holder’s registered address. 
  

	 	3.	Paying Agent and Registrar. 

  
 Initially, U.S. Bank National Association (the “Trustee”) will act as Paying Agent and Registrar. The Company may change any Paying
Agent, Registrar or co-Registrar without notice to the Holders. Neither the Company nor any Affiliate of the Company shall act as Paying Agent or Registrar. 
  

	 	4.	Indenture. 

  
 The Notes and the Guarantees were issued under an Indenture, dated as of August 12, 2004 (the “Indenture”), among the Company, the
Guarantors named therein and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the

 B-3 

 the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes
are referred to the Indenture and the TIA for a statement of such terms. The Notes are senior secured obligations of the Company. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same
may be amended from time to time. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. 
  

	 	5.	Redemption.

 (1) 100% of the aggregate principal amount of the Notes being redeemed; and 
  
 (2) the sum of the present values of 105.688% of the aggregate principal amount of such Notes and scheduled
payments of interest on such Notes to and including August 15, 2008, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, together with, in
each case, accrued and unpaid interest and Additional Interest, if any, to the Redemption Date (subject to the right of the right of holders of record on the relevant record date to received interest due on the relevant Interest Payment Date).

  
 Any such redemption, purchase or notice pursuant to this
Section 5(a) may, at the Company’s discretion, be subject to satisfaction of one or more conditions precedent, including but not limited to the occurrence of a Change of Control. 
  
 (b) Optional Redemption on or after August 15, 2008. Except as described in Section 5(a) and (c), the Notes are not
redeemable before August 15, 2008. Thereafter, the Company may on any one or more occasions redeem the Notes. The Notes will be redeemed at their option, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following
redemption prices (expressed as percentages of the aggregate principal amount thereof) if redeemed during the twelve-month period commencing on August 15 of the year set forth below:

Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes ever issued under this Indenture. The Notes will be redeemed at a redemption price of 111.375% of the aggregate principal amount thereof, plus accrued and unpaid
interest and Additional Interest, if any, to the date of redemption, provided that:

 (d) Notice of Redemption. Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such
Holder’s registered address. If fewer than all of the Notes are to be redeemed, at any time, selection of Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if
any, on which the Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee deems to be fair and appropriate; provided that no partial redemption will reduce the principal amount of a
Note not redeemed to a denomination of less than $1,000; and provided, further, that any such partial redemption made with the proceeds of an Equity Offering will be made only on a pro rata basis or on as nearly a pro rata basis as
practicable (subject to the procedures of the DTC or any other depository) unless such method is otherwise prohibited. Notes in denominations of $1,000 or more may be redeemed in part. 
  
 Any notice of redemption under Section 5(a) may provide that payment of the price and performance of the Company’s
obligations with respect to such redemption or purchase may be performed by any other Person.

 Attention: Elizabeth C. Hammer 
  
 Sheffield Steel Corporation, a Delaware corporation (“Tenant”), and the undersigned,
                                        
         (“Landlord”), are parties to a lease, dated
                                        
(the “Lease”), demising the premises legally (or otherwise) described on Exhibit A attached hereto and made a part hereof (the “Leased Premises”). A copy of the Lease is attached hereto as Exhibit B. 
  
 Tenant has entered into, or intends to enter into, certain financing
arrangements with U.S. Bank National Association, as Collateral Agent (“Collateral Agent”) for holders of certain Senior Secured Notes due in 2011 (“Senior Noteholders” and, together with the Collateral Agent, the “Secured
Parties”). 
  
 To induce Collateral Agent, the Senior
Noteholders and Tenant to enter into said financing arrangements, and for other good and valuable consideration, Landlord hereby agrees that: 
  
 1. Landlord hereby confirms that Tenant is the holder of the tenant’s interest under the Lease. 
  
 2. Landlord hereby consents to and approves of (to the extent such consent
and approval is required by the Lease) the execution and delivery by Tenant of one or more security agreements and UCC-1 Financing Statements (collectively, the “Security Agreements”), pursuant to which the Tenant will grant a security
interest in, among other things, all of its right, title and interest in and to all of Tenant’s assets and property located on or about the Leased Premises, including without limitation, all of Tenant’s machinery, equipment, furniture,
fixtures (excluding the Landlord’s overhead crane located on the Leased Premises), inventory and all additions, replacements or substitutions therefor, whether or not affixed to the Leased Premises (collectively, the “Collateral”) in
favor of Collateral Agent for the benefit of the Secured Parties). 
  
 3. Landlord acknowledges that this letter serves as a notification of the Secured Parties’ interests in the Collateral. 
  
 4. Neither Landlord nor Tenant is in default under the terms of the Lease and no event has occurred which, with the giving of notice or the passage of

 F-1-1 

 5. As of the date hereof Tenant has paid all rent, additional rent and other charges and amounts due to
Landlord under the Lease or with respect to the Leased Premises. 
  
 6. The Lease has not been amended, modified, terminated or revoked, is in full force and effect, and is binding and enforceable against Landlord. 
  
 7. None of the Collateral and no other moveable assets of Tenant (including, without limitation, equipment and trade fixtures which may or may not be
affixed to the Leased Premises) located on or about the Leased Premises will be deemed by Landlord to be fixtures or to constitute part of the Leased Premises. 
  

8. Landlord will not assert, and therefore waives, any liens, whether granted by the Lease, statute or otherwise (including, without limitation, rights
of levy or distraint for rent), against the Collateral or any other moveable property of Tenant located on the Leased Premises, including, without limitation, Tenant’s machinery, equipment, furniture, fixtures, inventory and all additions,
replacements or substitutions therefor, whether or not affixed to the Leased Premises (collectively, the “Property”) in which the Lenders have a security interest; provided, however, that the foregoing shall not prevent Landlord from
pursuing any causes of action for unpaid rent or breach of the Lease. 
  
 9. (a) Landlord will provide Collateral Agent with written notice of any default by Tenant under the Lease. Prior to terminating the Lease or exercising any of Landlord’s rights and remedies thereunder, Landlord will permit Collateral
Agent the same opportunity to cure or cause to be cured such default as is granted Tenant under the Lease, provided, however, that Collateral Agent shall have at least: (i) with respect to monetary defaults, ten (10) days following receipt of such
notice to cure such monetary defaults; and (ii) with respect to other defaults, thirty (30) days following receipt of such notice to cure such defaults (provided, however, that if the nature of any non-monetary default is such that the same cannot
be cured within said thirty (30) day period, Collateral Agent shall be given such additional period of time as may be necessary to cure the default provided that Collateral Agent commence the cure within said thirty (30) day period and proceeds
diligently thereafter to complete such cure). 
  
 (b) Landlord also will permit Collateral Agent or its designees to remain on the Leased Premises for a period of up to one hundred and eighty (180) days following receipt by Collateral Agent of written notice from Landlord that Landlord has
terminated the Lease; provided, however, that Tenant or Collateral Agent shall pay the rent and other amounts due under the Lease for the period of occupancy by the Collateral Agent or its designees, such amount to be pro-rated on a per diem basis.

  
 10. Collateral Agent may, at no expense to Landlord and in
accordance with the terms of their respective loan documents, enter onto the Leased Premises at any time or times and take possession of, sever, or remove the Collateral and the Property or any part thereof and said Collateral and Property upon
severance and/or removal may be sold, transferred or otherwise disposed of free and discharged of all liens, claims, demands, rights or interests of Landlord. In such event, Collateral Agent agrees to repair any damage to the Leased Premises.

  
 11. Notwithstanding anything in this Agreement to the
contrary, (i) Collateral Agent shall not be deemed to have assumed any other obligations or liabilities of Tenant under the 
  

 F-1-2 

 Lease by electing to occupy or enter the Leased Premises as provided above, and (ii) Collateral Agent shall not have any
duty or obligation to remove or dispose of all or any part of the Collateral or Property left on the Leased Premises by Tenant. 
  
 12. Landlord will give copies of all notices of default sent to Tenant under the Lease to Collateral Agent at:
