 INDENTURE dated as of January 25, 2007 (this “Indenture”), among METAL SERVICES
MERGER SUB CORP., a Delaware corporation (the “Company”), and the Guarantor (as defined herein) listed on the signature pages hereto and THE BANK OF NEW YORK, a New York banking corporation, as Trustee (the
“Trustee”). 
 Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of
the Holders of the Company’s Initial Securities, Exchange Securities and Private Exchange Securities (collectively, the “Securities”): 
 Article I 
 Definitions And Incorporation By Reference 
 SECTION 1.01. Definitions. 
 “ABL
Facility” means the credit agreement among the Company, Metal Services Acquisition Corp., certain Subsidiaries of the Company, the financial institutions named therein, Credit Suisse, as Administrative Agent, and CIT Business Capital, as
Collateral Agent, dated as of the Issue Date, as amended, extended, renewed, restated, supplemented, waived, replaced (whether or not upon termination, and whether with the original agents, lenders or otherwise), restructured, repaid, refunded,
refinanced or otherwise modified from time to time, including any agreement or indenture or multiple agreements and indentures extending the maturity thereof, refinancing, replacing or otherwise restructuring all or any portion of the Indebtedness
under such agreement or agreements or indenture or indentures or any successor or replacement agreement or agreements or indenture or indentures or increasing the amount loaned or issued thereunder or altering the maturity thereof and adding
Restricted Subsidiaries as additional borrowers, issuers or guarantors thereunder. 
 “Acquired Debt” means, with respect to
any specified Person: 
 (1) Indebtedness of any other Person existing at the time such other Person is merged with or into or
became a Subsidiary of such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Subsidiary of such specified Person; and 
 (2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person. 
 “Additional Securities” means Securities issued under this Indenture after the Issue Date and in compliance with Section 2.14 and
4.03, it being understood that any Securities issued in exchange for or replacement of any Initial Security issued on the Issue Date shall not be an Additional Security, including any such Securities issued pursuant to a Registration Rights
Agreement. 







 “Adjusted Treasury Rate” means, with respect to any redemption date, (1) the yield,
under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of
Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities”, for the maturity corresponding to the
Comparable Treasury Issue (if no maturity is within three months before or after February 1, 2011, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury
Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not
contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, in each
case calculated on the third Business Day immediately preceding the redemption date, in each case, plus 0.50%. 
 “Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For purposes of this definition,
“control,” as used with respect to any Person, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting
securities, by agreement or otherwise. For purposes of this definition, the terms “controlling,” “controlled by” and “under common control with” shall have correlative meanings. 
 “Applicable Premium” means with respect to a Security at any redemption date, the greater of (1) 1.00% of the principal
amount of such Security and (2) the excess of (A) the present value at such redemption date of (i) the redemption price of such Security on February 1, 2011 (such redemption price being described in the second paragraph of
paragraph 5 of the Securities, exclusive of any accrued interest) plus (ii) all required remaining scheduled interest payments due on such Security through February 1, 2011 (but excluding accrued and unpaid interest to the redemption
date), computed using a discount rate equal to the Adjusted Treasury Rate, over (B) the principal amount of such Security on such redemption date. 
 “Asset Sale” means: 
 (1) the sale, lease, conveyance or other disposition
(a “Disposition”) of any assets or rights (including by way of a sale and leaseback) outside of the ordinary course of business (provided, however, that the sale, lease, conveyance or other disposition of all or
substantially all of the assets of the Company and its Restricted Subsidiaries taken as a whole will be governed by Sections 4.10 and 5.01 and not by Section 4.03); and 
  

 2 








 (2) the issue or sale by the Company or any Restricted Subsidiary of Equity Interests of
any of the Company’s Restricted Subsidiaries; 
 in the case of either clause (1) or (2), whether in a single
transaction or a series of related transactions: 
 (a) that have a fair market value in excess of $3.0 million; or

 (b) for net proceeds in excess of $3.0 million. 
 Notwithstanding the preceding, the following items shall not be deemed to be Asset Sales: 
 (1) a Disposition of assets by the Company to the Company or a Restricted Subsidiary or by a Restricted Subsidiary to the Company or to
any other Restricted Subsidiary; 
 (2) an issuance of Equity Interests by a Restricted Subsidiary to the Company or to
another Restricted Subsidiary; 
 (3) the issuance of Equity Interests by a Restricted Subsidiary in which the percentage
interest (direct and indirect) in the Equity Interests of such Person owned by the Company after giving effect to such issuance, is at least equal to the percentage interest prior to such issuance; 
 (4) a Restricted Payment that is permitted by Section 4.04; 
 (5) a Disposition in the ordinary course of business; 
 (6) any Liens permitted by this Indenture and foreclosures thereon; 
 (7) any exchange of property pursuant to Section 1031 of the Code, for use in a Permitted Business; 
 (8) the license, lease, assignment, sublicense or sublease of any property, or any termination or expiration of any of the foregoing, so
long as the same does not materially interfere with the business of the Company and its Restricted Subsidiaries taken as a whole; 
 (9) the unwinding of any Hedging Obligations; 
 (10) sales or forgiveness of accounts receivable in the ordinary
course of business in connection with the collection or compromise thereof; 
  

 3 








 (11) the abandonment or other disposition of intellectual property that is no longer
economically practicable to maintain or useful in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole; 
 (12) any Disposition of property resulting from a casualty event or the taking thereof by any Person pursuant to the power of eminent domain, condemnation or otherwise, or pursuant to a sale of thereof to a purchaser
with such power under threat of such a taking; and 
 (13) the sale or other disposition of cash or Cash Equivalents.

 “Attributable Debt” in respect of a Sale and Leaseback Transaction means, at the time of determination, the present value
of the total obligations of the lessee for net rental payments during the remaining term of the lease included in such Sale and Leaseback Transaction. For purposes hereof such present value shall be calculated using a discount rate equal to the rate
of interest then borne by loans outstanding under the Term Facility; provided, however, that if such sale and leaseback transaction results in a Capital Lease Obligation, the amount of Indebtedness represented thereby will be
determined in accordance with the definition of “Capital Lease Obligation.” 
 “Board of Directors” means
(1) with respect to a Person that is a corporation or limited liability company, the board of directors, board of managers or equivalent governing board of such Person or any duly authorized committee thereof, (2) with respect to a Person
that is a limited partnership, the board of directors, board of managers or equivalent governing board of such Person’s general partner, and (3) with respect to any other Person, the governing body of such Person most closely approximating
the governing bodies contemplated in the preceding clauses (1) and (2). 
 “Board Resolution” means a copy of a
resolution certified by the Secretary or an Assistant Secretary of any Person to have been duly adopted by the Board of Directors of such Person and to be in full force and effect on the date of such certification, and delivered to the Trustee.

 “Business Day” means each day which is not a Legal Holiday. 
 “Capital Lease Obligation” of any Person means the obligations of such Person to pay rent or other amounts under any lease of (or other
arrangement conveying the right to use) real or personal property, or a combination thereof, which obligations are required to be classified and accounted for as capital leases on a balance sheet of such Person under GAAP, and the amount of such
obligations shall be the amount thereof accounted for as a liability determined in accordance with GAAP; and the Stated Maturity thereof shall be the date of the last payment of rent or any other amount due under such lease prior to the first date
upon which such lease may be prepaid by the lessee without payment of a penalty. 
 “Capital Stock” means: 
 (1) in the case of a corporation, corporate stock;

 (2) in the case of an association or business entity, any and all shares, interests,
participations, rights or other equivalents (however designated) of corporate stock; 
 (3) in the case of a partnership or
limited liability company, partnership or membership interests (whether general or limited); and 
 (4) any other interest or
participation that confers on a Person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing Person. 
 “Cash Equivalents” means:

 (2) Canadian dollars, Japanese yen, pounds sterling, euro or, in the case of any Foreign Subsidiary, such local currencies held by it from
time to time in the ordinary course of business;

 (4) certificates of deposit, time deposits, bankers acceptances and eurodollar time
deposits with maturities of one year or less from the date of acquisition, bankers’ acceptances with maturities not exceeding one year and overnight bank deposits, in each case with any commercial bank having, at the time of acquisition
thereof, capital and surplus in excess of $250,000,000; 
 (5) repurchase obligations for underlying securities of the types

 In the event that the Company or any Subsidiary incurs, assumes, guarantees, redeems, retires or
extinguishes any Indebtedness or issues or redeems Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the Fixed Charge Coverage Ratio is being calculated but prior to or simultaneously with the event for
which the calculation of the Fixed Charge Coverage Ratio is made (the “Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee, redemption,
retirement or extinguishing of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period (the “reference period”).

 For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and disposed
operations (as determined in accordance with GAAP) that have been made by the Company or any Subsidiary during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Calculation Date
shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (and the change in any associated Fixed Charges and the change in Consolidated Cash Flow
resulting therefrom) had occurred on the first day of the reference period; provided that any such pro forma adjustments shall be limited to those permitted or required by Article 11 of Regulation S-X under the Securities Act or as otherwise
reasonably determined in good faith by the chief financial officer of the Company. If since the beginning of such period any Person (that subsequently became a Subsidiary or was merged with or into the Company or any Subsidiary since the beginning
of such period) shall have made any Investment, acquisition, disposition, merger, consolidation or disposed operation that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving
pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, consolidation or disposed operation had occurred at the beginning of the reference period. If (i) any Restricted Subsidiary is designated as an
Unrestricted Subsidiary or (ii) any Unrestricted Subsidiary is designated as a Restricted Subsidiary, in either case during the reference period or subsequent to such reference period and on or prior to the Calculation Date, such designation
shall be deemed to have 

  

 13 








 
occurred on the first day of the reference period. Notwithstanding anything to the contrary in the foregoing, Consolidated Cash Flow shall be calculated
(a) without giving effect to the effects of purchase accounting or similar adjustments required or permitted by GAAP in connection with the Acquisition or any other acquisition of all or substantially all the assets or businesses of a Person or
of assets constituting a business unit, line of business or division of such a Person or not less than 100% (or such lesser percentage, when combined with the percentage of Equity Interest owned by the Company or a Subsidiary prior to such
acquisition, would equal 100%) of the Equity Interests (other than directors’ qualifying shares) of a Person and (b) with respect to any period during which such an acquisition occurs, on a pro forma basis after giving effect to such
acquisition (but only to the extent that an adjustment resulting from such acquisition would be a permitted or required adjustment to pro forma financial statements in compliance with Article 11 of Regulation S-X promulgated under the Securities Act
or to the extent such adjustment is reasonably determined in good faith by the chief financial officer of the Company). 
 For purposes of
this definition, whenever pro forma effect is to be given to a transaction, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Company. If any Indebtedness bears a floating rate of interest
and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to
such Indebtedness). Interest on a Capital Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Company to be the rate of interest implicit in such Capital Lease
Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such
Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have
been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate. 
 “Fixed Charges” means, with respect to any Person for any period, the sum, without duplication, of:

definition. 
 The amount of Indebtedness of any Person at any date shall be the outstanding balance at such date of all unconditional

longer a Restricted Subsidiary, then the Company shall be deemed to have made an Investment on the date of any such sale or disposition equal to the fair market value of the Equity

Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an 

  

 32 








 
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as
of such date and, if such Indebtedness is not permitted to be incurred as of such date by Section 4.03, the Company shall be in default of such Section 4.03. The Board of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary; provided, however, that such designation shall be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall be permitted only if (1) such Indebtedness is permitted by Section 4.03 and (2) no Default would be in existence following such designation. 
 “U.S. Government Obligations” means direct obligations (or certificates representing an ownership interest in such obligations) of the
United States of America (including any agency or instrumentality thereof) for the payment of which the full faith and credit of the United States of America is pledged and which are not callable at the issuer’s option.

 (1) the
sum of the products obtained by multiplying: (a) the amount of each then remaining installment, sinking fund, serial maturity or other required payments of principal, including payment at final maturity, in respect thereof, by (b) the
number of years (calculated to the nearest one-twelfth) that will elapse between such date and the making of such payment, by 
 (2) the then outstanding principal amount of such Indebtedness. 
 “Wholly Owned Subsidiary” means a Restricted
Subsidiary all the Capital Stock of which (other than directors’ qualifying shares) is owned by the Company or one or more other Wholly Owned Subsidiaries.

 Article II 
 The Securities 
 SECTION 2.01. Form
and Dating. Provisions relating to the Initial Securities, the Private Exchange Securities and the Exchange Securities are set forth in the Rule 144A/Regulation S/IAI Appendix attached hereto (the “Appendix”) which is hereby
incorporated in, and expressly made part of, this Indenture. The Initial Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in, and expressly
made a part of, this Indenture. The Exchange Securities, the Private Exchange Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part
of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form
acceptable to the Company). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture. 
 SECTION 2.02. Execution and Authentication. One Officer shall sign the Securities for the Company by manual or facsimile signature. 
 If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless. 
  

 35 








 A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate
of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 On the Issue Date, the Trustee shall authenticate and deliver $225,000,000 of 9 3/4% Senior Subordinated Notes Due 2015 and, at any time and from time to time thereafter, the Trustee shall
authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed (by manual or facsimile signature) by two Officers or by an Officer and either
an Assistant Treasurer or an Assistant Secretary of the Company. Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of an issuance
of Additional Securities pursuant to Section 2.14 after the Issue Date, shall certify that such issuance is in compliance with Section 4.03. 
 The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and
demands. 
 SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented
for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their
transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent. 
 The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall
incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar
or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly Owned Subsidiary incorporated or organized within The United States of America may act
as Paying Agent, Registrar, co-registrar or transfer agent. 
 The Company initially appoints the Trustee as Registrar and Paying Agent in
connection with the Securities. 
 SECTION 2.04. Paying Agent To Hold Money in Trust. On or prior to each due date of the principal
and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to 

  

 36 








 
agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the
payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent
and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall
have no further liability for the money delivered to the Trustee. 
 SECTION 2.05. Securityholder 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 Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days
before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. 
 SECTION 2.06. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and
Section 8-401(a) of the Uniform Commercial Code are met. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall
make the exchange as requested if the same requirements are met. 
 SECTION 2.07. Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of
the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their
expenses in replacing a Security. 
 Every replacement Security is an additional Obligation of the Company. 
 SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this Section as not outstanding. Except as set forth in Section 2.09, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the
Security; provided, however, that Securities held, directly or indirectly, by the Company or its Affiliates shall not be deemed outstanding for purposes of the third paragraph of paragraph 5 of the Securities. 
  

 37 








 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee
and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code). 
 If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all
principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Securityholders on that date
pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 
 SECTION 2.09. Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or any
Subsidiary Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary Guarantor, will be considered as though not outstanding, except that for the
purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Securities that a Trust Officer of the Trustee actually knows are so owned will be so disregarded. 
 SECTION 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. 
 SECTION 2.11.
Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and deliver a certificate
of such disposition to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for
cancellation. 
 SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company
shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner, in each case as provided in the Notes. The Company may pay the defaulted interest to the persons 

  

 38 








 
who are Securityholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 
 SECTION 2.13. CUSIP Numbers, ISINs, etc. The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common
Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such
notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers
applicable to the Securities. 
 SECTION 2.14. Issuance of Additional Securities. After the Issue Date, the Company shall be entitled,
subject to its compliance with Section 4.03, to issue Additional Securities under this Indenture, which Securities shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance
and issue price. All the Securities issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase. 
 With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a
copy of each which shall be delivered to the Trustee, the following information: 
 (1) the aggregate principal amount of such
Additional Securities to be authenticated and delivered pursuant to this Indenture and the provision of Section 4.03 that the Company is relying on to issue such Additional Securities; 
 (2) the issue price, the issue date and the CUSIP number of such Additional Securities; provided, however, that no
Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the Code; and 
 (3) whether such Additional Securities shall be Initial Securities or shall be issued in the form of Exchange Securities as set forth in
Exhibit A. 
 Article III 
 Redemption 
 SECTION 3.01. Notices to Trustee. If the Company elects to redeem Securities pursuant to paragraph 5 of
the Securities, it shall notify the Trustee in 

  

 39 








 
writing of the redemption date, the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption will
occur. 
 The Company shall give each notice to the Trustee provided for in this Section at least 60 days before the redemption date
unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein. 
 SECTION 3.02. Selection of Securities to Be Redeemed. If fewer than all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata to the extent practicable. The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have
denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in principal amounts of $2,000 or a whole multiple of $1,000 in excess of $2,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed. 
 SECTION 3.03. Notice of Redemption. At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall mail
a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address. 
 The
notice shall identify the Securities to be redeemed and shall state: 
 (1) the redemption date; 
 (2) the redemption price; 
 (3) the name and address of the Paying Agent; 
 (4) that Securities called for redemption
must be surrendered to the Paying Agent to collect the redemption price; 
 (5) if fewer than all the outstanding Securities
are to be redeemed, the identification and principal amounts of the particular Securities to be redeemed; 
 (6) that, unless
the Company defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and
after the redemption date; 
 (7) the “CUSIP” number, ISIN or “Common Code” number, if any, printed on the
Securities being redeemed; and 
  

 40 








 (8) that no representation is made as to the correctness or accuracy of the
“CUSIP” number, ISIN, or “Common Code” number, if any, listed in such notice or printed on the Securities. 
 At the
Company’s request delivered to the Trustee at least 10 days before such notice is to be given (unless a shorter period shall be acceptable to the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the
Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section. 
 SECTION 3.04.
Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice. Upon surrender to the Paying Agent, such
Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date),
and such Securities shall be canceled by the Trustee. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 
 SECTION 3.05. Deposit of Redemption Price. Prior to the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a
Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date other than Securities or portions of Securities called for
redemption which have been delivered by the Company to the Trustee for cancellation. 
 SECTION 3.06. Securities Redeemed in Part.
Upon surrender of a Security that is redeemed in part and upon the cancellation by the Trustee of the original Security, the Company shall execute and the Trustee shall authenticate for the Holder (at the Company’s expense) a new Security equal
in principal amount to the unredeemed portion of the Security surrendered. 
 Article IV 
 Covenants 
 SECTION 4.01. Payment
of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal and interest shall be considered paid on the date due if on
such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture. 
 The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

 41 








 SECTION 4.02. SEC Reports. So long as any Securities are outstanding, the Company will
(i) furnish to the Holders or cause the Trustee to furnish to the Holders in each case within the time periods that such information would have otherwise been required to have been provided to the SEC if the rules and regulations applicable to
the filing of such information were applicable to the Company and (ii) post on its website within 10 Business Days thereafter: 
 (1) all quarterly and annual information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of
Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s certified independent accountants in accordance with the professional standards
of the American Institute of Certified Public Accountants; and 
 (2) all current reports that would be required to be filed
with the SEC on Form 8-K if the Company were required to file such reports. 
 The availability of the foregoing materials on the SEC’s
Electronic Data Gathering, Analysis, and Retrieval (EDGAR) service shall be deemed to satisfy the Company’s delivery obligation under clauses (i) and (ii) of this Section 4.02. 
 Following the consummation of the exchange offer or registration of the Securities contemplated by the Registration Rights Agreement, whether or not
required by the SEC, the Company will file a copy of all the information and reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC’s rules and regulations
(unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. In addition, the Company has agreed that, for so long as any Securities remain outstanding, it will
furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d) (4) under the Securities Act. The Company will at all times comply with Trust
Indenture Act Section 314(a). 
 If Holdco has filed with the SEC and provided to the Trustee and the Holders the reports described
above with respect to Holdco (including any financial information required by Rule 3-10 of Regulation S-X and, if Holdco, directly or indirectly, holds any material assets or conducts any material business other than the assets of, or the business
conducted by, the Company and its Subsidiaries, a separate “Management’s Discussion and Analysis of Financial Condition and Results of Operations” with respect to the Company and its Restricted Subsidiaries on a consolidated basis),
the Company shall be deemed to be in compliance with this Section 4.02. 
 Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from 

  

 42 








 
information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officers’ Certificates). 
 SECTION 4.03. Limitation on Indebtedness and Issuance of Preferred Stock. (a) The
Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness (including Acquired Debt) and the Company shall not permit any of its Restricted Subsidiaries to issue any shares of
Preferred Stock; provided, however, that the Company or any of the Subsidiary Guarantors may Incur Indebtedness (including Acquired Debt) and any of the Subsidiary Guarantors may issue Preferred Stock if the Fixed Charge Coverage Ratio
for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Preferred Stock is issued would have
been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred, or Preferred Stock had been issued, as the case may be, at the
beginning of such four-quarter period. 
 (b) Section 4.03(a) will not prohibit the incurrence of any or the following
items of Indebtedness (collectively, “Permitted Debt”): 
 (1) the incurrence by the Company or any
Restricted Subsidiary of Indebtedness under the Senior Credit Facilities and the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a
principal amount equal to the face amount thereof) up to an aggregate principal amount then outstanding equal to $425.0 million less the amount of any such Indebtedness incurred pursuant to this Section 4.03(b)(1) that is permanently
retired with Net Proceeds applied from and after the Issue Date to reduce the outstanding amounts under the Senior Credit Facilities in accordance with Section 4.06; 
 (2) the incurrence by the Company or any Restricted Subsidiary of Existing Indebtedness; 
 (3) the incurrence by the Company and the Subsidiary Guarantors of Indebtedness represented by the Securities originally issued on the
Issue Date and the related Subsidiary Guaranties, and the Exchange Securities and related Subsidiary Guaranties to be issued pursuant to the Registration Rights Agreement in respect thereof; 
 (4) the incurrence by the Company or any Restricted Subsidiary of Indebtedness represented by Capital Lease Obligations, mortgage
financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used or useful in the business of the Company
or such Restricted Subsidiary (whether through the direct purchase of assets or the Capital Stock of any Person owning such assets) and Permitted Refinancing 

  

 43 








 
Indebtedness in respect thereof, in an aggregate principal amount or accreted value, as applicable, not to exceed at any time outstanding the greater of
$25.0 million and 3.5% of Total Assets at the time of any incurrence under this Section 4.03(b)(4); 
 (5) Indebtedness
or Preferred Stock (x) incurred or issued to finance the acquisition of any Person or assets or (y) of Persons that are acquired by the Company or any Restricted Subsidiary or merged into the Company or any Restricted Subsidiary pursuant
to a transaction not prohibited under the terms of this Indenture; provided that after giving effect to such acquisition or merger, the Fixed Charge Coverage Ratio of the Company is greater than 1.75 to 1.0; 
 (6) Indebtedness arising from agreements of the Company or any Restricted Subsidiary providing for indemnification, adjustment of purchase
price, earn-out or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, asset or Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such
business, assets or Subsidiary for the purpose of financing such acquisition; provided, however, that (a) such Indebtedness is not reflected on the balance sheet of the Company or any Restricted Subsidiary (contingent obligations
referred to in a footnote or footnotes to financial statements and not otherwise reflected on the balance sheet will not be deemed to be reflected on such balance sheet for purposes of this Section 4.03(b)(6)) and (b) the maximum assumable
liability in respect of such Indebtedness shall at no time exceed the gross proceeds including non-cash proceeds (the fair market value of such non-cash proceeds being measured at the time received and without giving effect to any such subsequent
changes in value) actually received by the Company or such Restricted Subsidiary in connection with such disposition; 
 (7)
the incurrence by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance, defease or discharge Indebtedness incurred pursuant to Section 4.03(a)
or Sections 4.03(b)(2), (3), (5), (7) or (15); 
 (8) the incurrence by the Company or any Restricted Subsidiary of
intercompany Indebtedness between the Company and any Restricted Subsidiary; provided, however, that: 
 (a) if
the Company or any Subsidiary Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Subsidiary Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with
respect to the Securities, in the case of the Company, or the Subsidiary Guaranty of such Subsidiary Guarantor, in the case of a Subsidiary Guarantor; and 
 (b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the 

  

 44 








 
Company or a Restricted Subsidiary or (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a
Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, not permitted by this Section 4.03(b)(8); 
 (9) the incurrence by the Company or any Restricted Subsidiary of Hedging Obligations incurred with a bona fide intention to limit
interest rate risk or exchange rate risk associated with Indebtedness or operations of the Company and its Subsidiaries; 
 (10) the guarantee by the Company or a Subsidiary Guarantor of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be incurred by another provision of this Section 4.03(b) (other than Indebtedness incurred
pursuant to Sections 4.03(b)(18) and (24)); 
 (11) the issuance by a Restricted Subsidiary to the Company or any Restricted

and (b) any sale or other transfer of any such Preferred Stock to a Person that is neither the Company nor a Restricted Subsidiary shall be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted Subsidiary
that is not permitted by this Section 4.03(b)(11); 
 (12) the incurrence by the Company or any Restricted Subsidiary of
Indebtedness in respect of workers’ compensation claims, self-insurance obligations, indemnities, bankers’ acceptances, performance, completion and surety bonds or guarantees, and similar types of obligations in the ordinary course of

of such Indebtedness or Preferred Stock, together with any other outstanding Indebtedness or Preferred Stock incurred pursuant to this Section 4.03(b)(14), does not exceed $20.0 million; 
 (15) the incurrence of Indebtedness of the Company and Indebtedness or Preferred Stock of any Subsidiary Guarantor equal to 100% of the

equity capital of the Company, Equity Interests of any of the Company’s direct or indirect parent entities (in each case, other than proceeds of sales of Equity Interests to any Subsidiary of the Company) to the extent such net cash proceeds

 (23) the incurrence by the Company or any Restricted Subsidiary of Subordinated Obligations or Preferred Stock owed or issued to one or
more Permitted Holders in an aggregate outstanding principal amount not to exceed $50.0 million at any time; provided, however, that (A) interest on such Subordinated Obligations is not payable in cash, (B) such Subordinated
Obligations do not mature and do not require any scheduled or mandatory prepayments until after the stated maturity date of the Securities and (C) such Subordinated Obligations are not secured; 
  

 46 








 (24) the incurrence by a Foreign Subsidiary of (x) Indebtedness or Preferred Stock

 (25) the incurrence by the Company or any Restricted

Section 4.03(b)(25), not to exceed $30.0 million. 
 (c) For purposes of determining compliance with this
Section 4.03, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in Section 4.03(b)(1) through (25) or is entitled to be incurred pursuant to
Section 4.03(a), the Company shall be permitted to classify such item of Indebtedness in any manner that complies with this Section 4.03 (except that Indebtedness incurred under the Senior Credit Facilities on the Issue Date shall be
deemed to have been incurred pursuant to Section 4.03(b)(1)). In addition, the Company may, at any time, change the classification of an item of Indebtedness or any portion thereof (except for Indebtedness incurred under
Section 4.03(b)(1)) to any other clause of Section 4.03(b) or Section 4.03(a); provided, however, that the Company would be permitted to incur such item of Indebtedness (or portion thereof) pursuant to such other clause
of Section 4.03(b) or Section 4.03(a), as the case may be, at such time of reclassification. The accrual of interest, the accrual of dividends, the accretion or amortization of original issue discount, the payment of interest on any
Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form of additional
shares of the same class of Disqualified Stock shall not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.03. 
 (d) Notwithstanding any other provision of this Section 4.03, the maximum amount of Indebtedness that the Company or any Restricted
Subsidiary may incur pursuant to this Section 4.03 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 (e) Notwithstanding Section 4.03(a) or 4.03(b), the Company shall not, and shall not permit its Restricted Subsidiaries to, Incur any
Indebtedness that 

  

 47 








 
is both: (1) subordinate in right of payment to any Senior Indebtedness; and (2) senior in right of payment to the Securities or any Subsidiary
Guaranty. Neither the existence nor lack of a security interest nor the priority of any such security interest shall be deemed to affect the ranking or right of payment of any Indebtedness. 
 SECTION 4.04. Limitation on Restricted Payments. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, make a Restricted Payment if at the time the Company or such Restricted Subsidiary makes such Restricted Payment: 
 (1) a Default shall have occurred and be continuing or would occur as a consequence thereof; 
 (2) the Company is not able to Incur an additional $1.00 of Indebtedness under Section 4.03(a); or 
 (3) such
Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by Sections 4.04(b)(2), (3), (4), (6), (7),
(8), (9), (10) and (11)), is not greater than the sum, without duplication, of: 
 (A) 50% of the Consolidated Net Income
of the Company for the period (taken as one accounting period) from the beginning of the fiscal quarter in which the Issue Date occurs to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are
available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus 
 (B) 100% of the aggregate net proceeds received by the Company after the Issue Date as a contribution to its common equity capital or received by the Company from the issue or sale after the Issue Date (other than to
a Subsidiary of the Company) of Qualified Equity Interests or of Disqualified Stock or debt securities of the Company that have been converted into or exchanged for such Qualified Equity Interests (but excluding any such net proceeds applied to
permit the incurrence of any Contribution Indebtedness); plus 
 (C) 100% of the net proceeds received by the Company
by means of (i) the sale or other disposition (other than to the Company or a Restricted Subsidiary) of Restricted Investments made by the Company and its Restricted Subsidiaries and repurchases and redemptions of such Restricted Investments
from the Company and its Restricted Subsidiaries and repayments of loans or advances which constitute Restricted Investments by the Company and its Restricted Subsidiaries in each case 

  

 48 








 
after the Issue Date or (ii) the sale (other than to the Company or a Restricted Subsidiary) of the Capital Stock of an Unrestricted Subsidiary;
plus 
 (D) if any Unrestricted Subsidiary (i) is redesignated as a Restricted Subsidiary, the fair market value
of such redesignated Unrestricted Subsidiary (as certified to the Trustee in an Officers’ Certificate) as of the date of its redesignation or (ii) pays any cash dividends or cash distributions to the Company or any Restricted Subsidiary,
100% of any such dividends or distributions made after the Issue Date. 
 (b) The preceding provisions shall not prohibit:

 (1) the payment of any dividend within 60 days after the date of declaration thereof, if at such date of declaration such
payment would have complied with the provisions of this Indenture; 
 (2) the making of any Restricted Payment in exchange
for, or out of the net cash proceeds of the substantially concurrent sale or issuance (other than to a Subsidiary of the Company) of, (a) Indebtedness of the sort contemplated in Section 4.03(b)(23) or (b) Qualified Equity Interests
or (c) from the substantially concurrent contribution to the common equity capital of the Company (but excluding any such net proceeds applied to permit the incurrence of any Contribution Indebtedness); provided, however, that the
amount of any such net cash proceeds that are utilized for any such Restricted Payment shall be excluded from Section 4.04(a)(3)(B) and shall not be applied to permit the payment of any other Restricted Payment; 
 (3) the defeasance, redemption, repurchase, repayment or other acquisition of subordinated Indebtedness of the Company or any Restricted
Subsidiaries with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; 
 (4) the payment of any
dividend (or in the case of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary to the holders of its Equity Interests on a pro rata basis, taking into account the relative preferences, if
any, of the various classes of equity interests in such Restricted Subsidiary; 
 (5) the repurchase, redemption or other
acquisition or retirement for value (or the distribution of amounts to any other direct or indirect parent of the Company to fund any such repurchase, redemption or other acquisition or retirement) of any Equity Interests of the Company or any
direct or indirect parent of the Company held by any current or former officer, director, consultant or employee of the Company or any Restricted Subsidiary (or any permitted transferees, assigns, estates or heirs of any of the foregoing);
provided, however, 

  

 49 








 
the aggregate amount paid by the Company and its Restricted Subsidiaries pursuant to this Section 4.04(b)(5) shall not exceed $5.0 million in any
calendar year (excluding for purposes of calculating such amount the amount paid for Equity Interests repurchased, redeemed, acquired or retired with the proceeds from the repayment of outstanding loans previously made by the Company or a Restricted
Subsidiary for the purpose of financing the acquisition of such Equity Interests), with unused amounts in any calendar year being carried over for one additional calendar year, subject to a maximum (without giving effect to the following proviso) of
$10.0 million in any calendar year; provided further, however, that such amount in any calendar year may be increased by an amount not to exceed: 
 (A) the net cash proceeds from the sale of Qualified Equity Interests of the Company and, to the extent contributed to the common equity
capital of the Company, Equity Interests of any of the Company’s direct or indirect parent entities (but excluding any such net proceeds applied to permit the incurrence of any Contribution Indebtedness), in each case to members of management,
directors or consultants of the Company, any of its Subsidiaries or any of its direct or indirect parent entities that occurs after the Issue Date, to the extent such cash proceeds have not otherwise been and are not thereafter applied to permit the
payment of any other Restricted Payment; plus 
 (B) the cash proceeds of key man life insurance policies received by
the Company and its Restricted Subsidiaries after the Issue Date; less  
 (C) the amount of any Restricted Payments
previously made pursuant to Sections 4.04(b)(5)(A) and (B); 
 provided further, however, that cancellation of Indebtedness owing to the
Company from members of management of the Company, any of its direct or indirect parent entities or any Restricted Subsidiary in connection with a repurchase of Equity Interests of the Company or any of its direct or indirect parent entities will
not be deemed to constitute a Restricted Payment for purposes of this Indenture; 
 (6) the declaration and payment of
dividends on Disqualified Stock in accordance with the certificate of designations therefor; provided, however, that such issuance of Disqualified Stock is permitted by Section 4.03; 
 (7) repurchases of Equity Interests deemed to occur upon the exercise of stock options to the extent that such Equity Interests represent
a portion of the exercise price thereof; 
 (8) payments permitted under clauses (7), (8) and (9) of
Section 4.07; 
 (9) payments made to purchase, redeem, defease or otherwise acquire or retire for value any Equity
Interests of the Company or any Restricted 

  

 50 








 
Subsidiary or any Subordinated Obligations of the Company or a Subsidiary Guarantor (other than Equity Interests or Subordinated Obligations issued to or at
any time held by an Affiliate of any such Person), in each case, pursuant to provisions requiring such Person to offer to purchase, redeem, defease or otherwise acquire or retire for value such Equity Interests or Subordinated Obligations upon the
occurrence of a Change of Control or with the proceeds of Asset Sales as defined in the charter provisions, agreements or instruments governing such Equity Interests or Subordinated Obligations; provided, however, that a Change of
Control Offer or Asset Sale Offer, as applicable, has been made and the Company has purchased all Securities validly tendered in connection with that Change of Control Offer or Asset Sale Offer; 
 (10) the declaration and payment of dividends on the Company’s common stock (or the payment of dividends to Holdco to fund a payment
of dividends on Holdco’s common stock), following the first Public Equity Offering that results in a Public Market, of up to 6% per annum of the net cash proceeds received by the Company therefrom and, in the case of an offering of Holdco,
contributed to the Company’s common equity capital; and 
 (11) other Restricted Payments in an aggregate amount up to
$20.0 million; 
 provided, however, that, in the case of Section 4.04(b)(9), no Default shall have occurred and be continuing or would
occur as a consequence of the making of the Restricted Payment contemplated thereby. 
 (c) The amount of all Restricted
Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the assets or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the
Restricted Payment. The fair market value of any assets or securities that are required to be valued by Section 4.04 will be determined in good faith by the Board of Directors of the Company. Such determination must be based upon an opinion or
appraisal issued by an Independent Financial Advisor if the fair market value exceeds $30.0 million. 
 SECTION 4.05. Dividend and Other
Payment Restrictions Affecting Restricted Subsidiaries. The Company shall not, and shall not permit its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction
on the ability of any Restricted Subsidiary to: (a) pay dividends or make any other distributions to the Company or any Restricted Subsidiary (i) on its Capital Stock or (ii) with respect to any other interest or participation in, or
measured by, its profits; (b) pay any Indebtedness owed to the Company or any Restricted Subsidiary; (c) make loans or advances to the Company or any Restricted Subsidiary; or (d) transfer any of its properties or assets to the
Company or any Restricted Subsidiary; however, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of: 
 (1) Existing Indebtedness and the Senior Credit Facilities as in effect as of the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or
refinancings, of any thereof; provided, however, that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not, taken as a whole, materially more restrictive with
respect to such dividend and other payment restrictions than those contained in those agreements as in effect on the Issue Date; 
  

 51 








 (2) this Indenture, the Securities, the Subsidiary Guaranties, the Exchange Securities or
the Registration Rights Agreement; 
 (3) any applicable law, rule, regulation or order; 
 (4) any instrument or agreement of a Person acquired by the Company or any Restricted Subsidiary as in effect at the time of such
acquisition (except to the extent incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired; provided, however, that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; 
 (5) customary non-assignment provisions in contracts and licenses entered into in the ordinary course of business; 
 (6) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose
restrictions on the property so acquired or leased of the nature described in Section 4.05(a)(4); 
 (7) secured
Indebtedness otherwise permitted under this Indenture, the terms of which limit the right of the debtor to dispose of the assets securing such Indebtedness; 
 (8) Permitted Refinancing Indebtedness; provided, however, that the material restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are not, taken as a whole, materially more restrictive with respect to such dividend and other payment restrictions than those contained in the agreements governing the Indebtedness being Refinanced;

 (9) any agreement for the sale or other disposition of a Restricted Subsidiary or an asset that restricts distributions by
such Restricted Subsidiary or transfers of such asset pending the sale or other disposition; 
 (10) Liens permitted to be
incurred under Section 4.11 that limit the right of the debtor to dispose of the assets subject to such Liens; 
 (11)
provisions limiting the disposition, dividend or distribution of assets or property in joint venture agreements, partnership agreements, limited 

  

 52 








 
liability company operating agreements, asset sale agreements, sale-leaseback agreements, stock or equity sale agreements and other similar agreements, which
limitation is applicable only to the assets or property that are the subject of such agreements; and 
 (12) restrictions on
cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. 
 SECTION 4.06.
Limitation on Sales of Assets. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate any Asset Sale unless: 
 (1) the Company (or such Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal
to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
 (2) at least 75% of
the consideration received therefor by the Company (or such Restricted Subsidiary, as the case may be) is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: 
 (A) any liabilities of the Company or any Restricted Subsidiary (as shown on the most recent consolidated balance sheet of the Company and
its Restricted Subsidiaries other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or any Subsidiary Guaranty) that are assumed by the transferee of any such assets pursuant to an agreement that
releases the Company or any such Restricted Subsidiary from further liability with respect to such liabilities; 
 (B) any
securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents within 180 days (to the extent of the
cash or Cash Equivalents received in that conversion); 
 (C) any stock or assets of the kind referred to in
Section 4.06(b)(2) or (4); and 
 (D) any Designated Non-cash Consideration received by the Company or any Restricted
Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.06(a)(2)(D) that is at that time outstanding, not to exceed $15.0 million
at the time of receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value. 

 

 53 








 (b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company
or any such Restricted Subsidiary may apply such Net Proceeds, at its option: 
 (1) to repay or repurchase Senior
Indebtedness of the Company or any Subsidiary Guarantor or any Indebtedness of any Restricted Subsidiary that is not a Subsidiary Guarantor; 
 (2) to make an Investment in (provided such Investment is in the form of Capital Stock), or to acquire all or substantially all of the assets of, a Person engaged in a Permitted Business if such Person is, or will
become as a result thereof, a Restricted Subsidiary; 
 (3) to make a capital expenditure; or 
 (4) to acquire assets (other than securities) to be used in a Permitted Business. 
 Pending the final application of any such Net Proceeds, the Company may temporarily reduce the revolving Indebtedness under the Senior Credit Facilities or otherwise
invest such Net Proceeds in any manner that is not prohibited by this Indenture. 
 (c) Any Net Proceeds from Asset Sales that
are not applied or invested as provided in paragraph (b) of this Section 4.06 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will be required to make an
offer to purchase from all Holders (an “Asset Sale Offer”) and, if applicable, redeem or purchase (or make an offer to do so) any other Senior Subordinated Indebtedness of the Company, the provisions of which require the Company to
redeem or purchase (or make an offer to do so) such Indebtedness with the proceeds from any Asset Sales, the maximum aggregate principal amount of Securities and such other Senior Subordinated Indebtedness that may be purchased (on a pro rata
basis) with such Excess Proceeds. The offer price for the Securities in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash and the redemption
or purchase price for such other Senior Subordinated Indebtedness shall be as set forth in the related documentation governing such Indebtedness. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such
Excess Proceeds for any purpose not prohibited by this Indenture. If the aggregate purchase price of the Securities and the other Senior Subordinated Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company
shall select the Securities to be purchased on a pro rata basis but in round denominations, which in the case of the Securities will be denominations of $2,000 initial principal amount and multiples of $1,000 thereafter. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds related to such Asset Sale Offer shall be reset at zero. 
  

 54 








 (d) (1) Promptly, and in any event within 10 days after the Company becomes obligated to
make an Asset Sale Offer, the Company shall deliver to the Trustee and send, by first-class mail to each Holder, a written notice stating that the Holder may elect to have his Securities purchased by the Company either in whole or in part (subject
to prorating as described in paragraph (c) of this Section 4.06 in the event the Asset Sale Offer is oversubscribed) in a minimum amount of $2,000 or larger integral multiples of $1,000 of principal amount, at the applicable purchase
price. The notice shall specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and all instructions and materials necessary to tender Securities pursuant to the Asset
Sale Offer. 
 (2) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as
provided above, the Company shall deliver to the Trustee an Officers’ Certificate as to (A) the amount of the Asset Sale Offer (the “Asset Sale Offer Amount”) and (B) the compliance of such allocation with
Section 4.06. On such date, the Company shall also irrevocably deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) an amount equal to the Asset Sale Offer Amount to
be held for payment in accordance with this Section. If the Asset Sale Offer includes other Senior Subordinated Indebtedness, the deposit described in the preceding sentence may be made with any other paying agent pursuant to arrangements
satisfactory to the Trustee. Upon the expiration of the period for which the Asset Sale Offer remains open (the “Asset Sale Offer Period”), the Company shall deliver to the Trustee for cancellation the Securities or portions thereof
which have been properly tendered to and are to be accepted by the Company. The Trustee shall, on the Purchase Date, mail or deliver payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the
event that the aggregate purchase price of the Securities delivered by the Company to the Trustee is less than the Asset Sale Offer Amount applicable to the Securities, the Trustee shall deliver the excess to the Company immediately after the
expiration of the Asset Sale Offer Period for application in accordance with this Section 4.06. 
 (3) Holders electing
to have a Security purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be
entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the Purchase Date, a telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the
Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing his election to have such Security purchased. Holders whose Securities are purchased only in part shall be issued new Securities equal in
principal amount to the unpurchased portion of the Securities surrendered. 
  

 55 








 (4) At the time the Company delivers Securities to the Trustee which are to be accepted
for purchase, the Company shall also deliver an Officers’ Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section. A Security shall be deemed to have been accepted
for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. 
 (e) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this
Section 4.06. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.06, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this Section 4.06 by virtue of its compliance with such securities laws or regulations. 
 SECTION
4.07. Limitation on Affiliate Transactions. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to,
or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any of its Affiliates (each, an “Affiliate
Transaction”), unless 
 (1) such Affiliate Transaction is on terms that are not materially less favorable to the
Company or such Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (2) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million, a resolution of the Board of Directors of the Company and an
Officers’ Certificate certifying that such Affiliate Transaction complies with Section 4.07(a)(1) above and that such Affiliate Transaction has been approved by a majority of the disinterested members (if any) of such Board of Directors;
and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $30.0 million, an opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
 (b) The following items shall not be deemed to be Affiliate Transactions and, therefore, will not be subject to Section 4.07(a):

 (1) transactions between or among the Company and its Restricted Subsidiaries; 
  

 56 








 (2) any Restricted Payment that is permitted by Section 4.04; 
 (3) reasonable loans, advances, fees, benefits and compensation paid or provided to, and indemnity provided on behalf of, officers,
directors, employees or consultants of the Company or any Restricted Subsidiary; 
 (4) transactions pursuant to any contract
or agreement in effect on the Issue Date as the same may be amended, modified or replaced from time to time so long as any such amendment, modification or replacement, taken as a whole, is no less favorable in any material respect to the Company or
such Restricted Subsidiary than the contract or agreement as in effect on the Issue Date; 
 (5) transactions with a Person
(other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (6) the issuance or sale of Qualified Equity Interests (and the exercise of any warrants, options or other rights to acquire Qualified
Equity Interests); 
 (7) to the extent that the Company and one or more of its Restricted Subsidiaries are members of a
consolidated, combined or similar income tax group of which a direct or indirect parent of the Company is the common parent, payment of dividends or other distributions by the Company or one or more of its Restricted Subsidiaries pursuant to a tax
sharing agreement or otherwise to the extent necessary to pay, and that are used to pay, any income taxes of such tax group that are attributable to the Company and its Restricted Subsidiaries and are not payable directly by the Company or any of
its Restricted Subsidiaries; provided, however, that the amount of any such dividends or distributions (plus any such taxes payable directly by the Company and its Restricted Subsidiaries) shall not exceed the amount of such taxes that
would have been payable directly by the Company and its Restricted Subsidiaries had the Company been the U.S. common parent of a separate tax group that included only the Company and its Restricted Subsidiaries; 
 (8) (a) the payment of fees to Sponsor on the Issue Date related to the Transactions as disclosed in the Offering Circular and the
payment of fees to Sponsor pursuant to the Management Agreement not to exceed $2.0 million (plus any amounts accrued pursuant to the following proviso) in any fiscal year of the Company; provided, however, that such payments may accrue
but may not be paid during the existence of an Event of Default arising from Section 6.01(1), (2) or (7); (b) any termination or other fee payable to the Sponsor upon a change of control or initial public equity offering of the
Company or any direct or indirect parent thereof as contemplated by the terms of the Management Agreement in effect on the Issue Date; and (c) payments by the Company to or on behalf of the 

  

 57 








 
direct or indirect parent of the Company in an amount sufficient to pay out-of-pocket legal, accounting and filing and other general corporate overhead costs
of such parent, customary salary, bonus and other benefits payable to officers, directors and employees of a direct or indirect parent of the Company and franchise taxes and other fees required to maintain its existence, actually incurred by such
parent; provided, however, that such costs, salaries, bonuses, benefits, taxes and fees are attributable to the ownership of the Company and its Restricted Subsidiaries; 
 (9) reimbursements of bona fide out-of-pocket expenses of Sponsor incurred in connection with services provided under the Management
Agreement or otherwise in connection with the general administration and management of Metal Services Acquisition Corp., Holdco, the Company and any Restricted Subsidiaries of the Company; provided, however, that, in the case of Metal

 (10) loans or advances to employees of the Company or any Restricted Subsidiary (x) in the ordinary course of business or (y) in
connection with the purchase by such Persons of Equity Interests of any direct or indirect parent of the Company so long as the cash proceeds of such purchase received by such direct or indirect parent are contemporaneously contributed to the common
equity capital of the Company; and 
 (11) transactions with customers, clients, suppliers or purchasers or sellers of goods
or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture that are on terms no less favorable than those that would have been obtained in a comparable transaction with an unrelated
party or on terms that are approved by the Board of Directors of the Company, including a majority of the disinterested directors. 
 SECTION
4.08. Limitation on Line of Business. The Company shall not, and shall not permit any Restricted Subsidiary, to engage in any business other than a Permitted Business, except to such extent as would not be material to the Company and its
Restricted Subsidiaries taken as a whole. 
 SECTION 4.09. Designation of Restricted and Unrestricted Subsidiaries. The Board of
Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default and the conditions set forth in the definition of “Unrestricted Subsidiary” are met. If
a Restricted Subsidiary is designated as an Unrestricted Subsidiary, all outstanding Investments owned by the Company and its Restricted Subsidiaries (except to the extent repaid in cash or Cash Equivalents) in the Subsidiary so designated will be
deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments pursuant to Section 4.04 or under one or more of the clauses of the definition of Permitted Investments, as determined
by the Company. All such 

  

 58 








 
outstanding Investments will be valued at their fair market value at the time of such designation, as certified to the Trustee in an Officers’
Certificate. That designation will only be permitted if such Restricted Payment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 SECTION 4.10. Change of Control. (a) If a Change of Control occurs, each Holder will have the right to require the Company to repurchase all
or any part (equal to $2,000 or any greater amount in multiples of $1,000) of that Holder’s Securities pursuant to the Change of Control Offer (as defined below). In the Change of Control Offer, the Company will offer a payment in cash equal to
101% of the aggregate principal amount of Securities repurchased plus accrued and unpaid interest thereon, if any, to the date of purchase (the “Change of Control Payment”). 
 (b) Within 60 days following any Change of Control, the Company shall mail a notice (the “Change of Control Offer”) to
each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Securities on a date (the “Change of Control Payment Date”) no earlier than 30 days and no later than 60 days
from the date the notice is mailed, other than as may be required by law, pursuant to the procedures required by this Indenture and described in such notice. Such notice shall state: 
 (1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s
Securities at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to
receive interest on the relevant interest payment date); 
 (2) the circumstances and relevant facts regarding such Change of
Control (including information with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control); 
 (3) the Change of Control Payment Date; and 
 (4) the instructions, as determined by the Company, consistent with this Section 4.10, that a Holder must follow in order to have its Securities purchased. 
 (c) Holders electing to have a Security purchased will be required to surrender the Security, with an appropriate form duly completed, to
the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders will be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the
purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing his election
to have such Security purchased. 
  

 59 








 (d) On the Change of Control Payment Date, the Company will: 
 (1) accept for payment all Securities or portions thereof in minimum amounts equal to $2,000 or an integral multiple of $1,000 in excess
thereof properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the
Change of Control Payment in respect of all Securities or portions thereof so tendered; and 
 (3) deliver or cause to be
delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company. 
 (e) The Company shall cause the Paying Agent to promptly mail to each Holder of Securities so tendered the Change of Control Payment for
such Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any;
provided, however, that each such new Security will be in a principal amount of $2,000 or any greater amount in multiples of $1,000. 
 (f) Notwithstanding the foregoing provisions of this Section 4.10, the Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.10 applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under
such Change of Control Offer. 
 (g) If making a Change of Control Payment would violate any outstanding Senior Indebtedness
of the Company, prior to complying with this Section 4.10, but in any event within 90 days following a Change of Control, the Company will either repay such Senior Indebtedness or obtain the requisite consents under the agreements governing
such Senior Indebtedness to permit the repurchase of Securities required by this Section 4.10. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

 (h) The Company shall comply, to the extent applicable, 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 Securities pursuant to this Section 4.10. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Indenture relating to such Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and 

  

 60 








 
shall not be deemed to have breached its obligations under this Indenture by virtue of its compliance with such securities laws or regulations. 

SECTION 4.11. Limitation on Liens. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create,
incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any property or assets, now owned or hereafter acquired unless: 
 (1) in the case of Liens securing Indebtedness that is expressly subordinated or junior in right of payment to the Securities, the
Securities are secured on a senior basis to the obligations so secured until such time as such obligations are no longer secured by a Lien; and 
 (2) in all other cases, the Securities are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien. 
 SECTION 4.12. Future Guarantors. The Company shall not permit any Domestic Restricted Subsidiary, directly or indirectly, to incur Indebtedness,
or guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company or any Restricted Subsidiary or issue any Preferred Stock, unless: 
 (1) such Indebtedness is incurred or such Preferred Stock is issued by such Restricted Subsidiary pursuant to Section 4.03(b)(2),
(4), (5)(y), (6), (7) (with respect to Permitted Refinancing Indebtedness in respect of Indebtedness initially incurred under Section 4.03(b)(2) or (5)(y) only), (8), (11), (12), (13), (14), (16), (19), (20) or (21) or
pursuant to Section 4.03(b)(10) (with respect to Indebtedness incurred under any of the foregoing clauses); 
 (2) such
Restricted Subsidiary is a Subsidiary Guarantor; or 
 (3) such Restricted Subsidiary simultaneously executes and delivers a
Guaranty Agreement and becomes a Subsidiary Guarantor, which guarantee shall (a) with respect to the incurrence of Senior Indebtedness, be subordinated in right of payment on the same terms as the Securities are subordinated to such Senior
Indebtedness and (b) with respect to the incurrence of any other Indebtedness or the issuance of Preferred Stock, be senior to or pari passu with such Restricted Subsidiary’s other Indebtedness or guarantee of or pledge to
secure such other Indebtedness. 
 SECTION 4.13. Compliance Certificate; Statement as to Default. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of
any Default and whether or not the signers know of any Default that occurred during such period. If they do, the certificate shall describe the Default, its 

  

 61 








 
status and what action the Company is taking or proposes to take with respect thereto. The Company also shall comply with TIA § 314(a)(4).

 The Company shall deliver to the Trustee, as soon as possible and in any event within ten days after the Company becomes aware of the
occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default and the action which
the Company proposes to take with respect thereto. 
 SECTION 4.14. Liquidated Damages Notice. In the event that the Company is
required to pay Liquidated Damages to holders of Notes pursuant to the Registration Rights Agreement, the Company will provide written notice (“Liquidated Damages Notice”) to the Trustee of its obligation to pay Liquidated Damages
no later than fifteen days prior to the proposed payment date for the Liquidated Damages, and the Liquidated Damages Notice shall set forth the amount of Liquidated Damages to be paid by the Company on such payment date. The Trustee shall not at any
time be under any duty or responsibility to any holder of Notes to determine the Liquidated Damages, or with respect to the nature, extent, or calculation of the amount of Liquidated Damages owed, or with respect to the method employed in such
calculation of the Liquidated damages. 
 Article V 
 Successor Company 
 SECTION 5.01. When Company May Merge or Transfer Assets. (a) The
Company may not (other than pursuant to the Merger): (x) consolidate or merge with or into another Person (whether or not the Company is the surviving corporation); or (y) sell, assign, transfer, convey or otherwise dispose of all or
substantially all of its properties or assets, in one or more related transactions, to another Person unless: 
 (1) either
(a) the Company is the surviving corporation or (b) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition shall have been
made is a corporation, limited liability company or partnership organized or existing under the laws of the United States, any State thereof or the District of Columbia; provided, however, that if such Person is a limited liability
company or partnership, a corporate Wholly Owned Subsidiary of such Person organized under the laws of the United States, any state thereof or the District of Columbia becomes a co-issuer of the Securities in connection therewith; 
 (2) the entity or Person formed by or surviving any such consolidation or merger (if other than the Company) or the entity or Person to
which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Securities and this Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to
the Trustee; 
  

 62 








 (3) immediately after such transaction no Default exists; 
 (4) (a) the Company or the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or
to which such sale, assignment, transfer, conveyance or other disposition shall have been made will, after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable four-quarter period, be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.03(a) or (b) the Fixed Charge Coverage Ratio of the Company or the Person formed by or surviving any such
consolidation, amalgamation or merger (if other than the Company), or to which such sale, assignment, transfer, conveyance or other disposition has been made, determined on a pro forma basis as if such transaction had occurred at the
beginning of the applicable four-quarter period and after giving effect to the transaction and any related financings, would not be less than the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for
which internal financial statements are available immediately preceding the date on which such transaction occurred; and 
 (5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture.

 The preceding Section 5.01(a)(4) shall not prohibit: (a) a merger between the Company and a Restricted Subsidiary or between Restricted
Subsidiaries; or (b) a merger between the Company and an Affiliate incorporated solely for the purpose of reincorporating the Company in another state of the United States. 
 In addition, the Company may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related
transactions, to any other Person. This Section 5.01 shall not be applicable to a sale, assignment, transfer, conveyance or other disposition of assets between or among the Company and any of its Restricted Subsidiaries. 
 (b) The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one
transaction or a series of transactions, all or substantially all of its assets to any Person unless: 
 (1) the resulting,
surviving or transferee Person (if not such Subsidiary) shall be a Person organized and existing under the laws of the jurisdiction under which such Subsidiary was organized or under the laws of the United States of America, or any State thereof or
the District of Columbia, and 

  

 63 








 
such Person shall expressly assume, by a Guaranty Agreement, all the obligations of such Subsidiary, if any, under its Subsidiary Guaranty; provided,
however, that the foregoing requirement shall not apply in the case of a Subsidiary Guarantor (x) that has been disposed of in its entirety to another Person (other than to the Company or an Affiliate of the Company), whether through a
merger, consolidation or sale of Capital Stock or assets or (y) that, as a result of the disposition of all or a portion of its Capital Stock, ceases to be a Subsidiary; provided further, however, that in the case of
clause (x) and (y), the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.06; 
 (2) immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any Indebtedness
which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such transaction), no Default shall have occurred and be continuing; and 
 (3) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation,
merger or transfer and such Guaranty Agreement, if any, complies with this Indenture. 
 The preceding Section 5.01(b)(2) shall not prohibit any
Subsidiary Guarantor that is a limited liability company from merging with an Affiliate solely for the purpose of reincorporating such Subsidiary Guarantor as a corporation. 
 (c) Notwithstanding anything to the contrary, the Transactions (including the Merger contemplated by the Stock Purchase Agreement) shall
be permitted without compliance with this Section 5.01. 
 Article VI 
 Defaults and Remedies 
 SECTION 6.01. Events of Default. An
“Event of Default” occurs if: 
 (1) the Company defaults in any payment of interest on any Security when the
same becomes due and payable, whether or not such payment shall be prohibited by Article 10 of this Indenture, and such default continues for a period of 30 days; 
 (2) the Company (A) defaults in the payment of the principal of any Security when the same becomes due and payable at its Stated
Maturity, upon optional redemption, upon declaration of acceleration or otherwise, whether or not such payment shall be prohibited by Article 10 of this Indenture or (B) fails to redeem or purchase Securities when required pursuant to this
Indenture or the Securities, whether or not such redemption or purchase shall be prohibited by Article 10 of this Indenture; 
  

 64 








 (3) the Company fails to comply with Section 4.10 or Section 5.01; 

(4) the Company fails to comply with Sections 4.04, 4.03 or 4.06 and such failure continues for 30 days after notice the notice
specified below; 
 (5) the failure by the Company or any Subsidiary Guarantor to comply for 60 days after notice with
its other agreements contained in this Indenture; 
 (6) Indebtedness of the Company, any Subsidiary Guarantor or any
Significant Subsidiary is not paid within any applicable grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $15.0 million;

 (7) the Company, any Subsidiary Guarantor or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy
Law: 
 (A) commences a voluntary case; 
 (B) consents to the entry of an order for relief against it in an involuntary case; 
 (C) consents to the appointment of a Custodian of it or for any substantial part of its property; or 
 (D) makes a general assignment for the benefit of its creditors; 
 or takes any comparable action under any foreign laws relating to insolvency; 
 (8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law (or any similar relief is granted under any
foreign laws) that: 
 (A) is for relief against the Company, any Subsidiary Guarantor or any Significant Subsidiary in an
involuntary case; 
 (B) appoints a Custodian of the Company, any Subsidiary Guarantor or any Significant Subsidiary or for
any substantial part of its property; or 
 (C) orders the winding up or liquidation of the Company, any Subsidiary Guarantor
or any Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 days; 
 (9) any judgment or decree is rendered for the payment of money in an amount, net of any insurance or indemnity payments actually received
in respect thereof prior to or within 60 days from the entry thereof, or to be received in respect thereof in the event any appeal thereof shall be unsuccessful, in excess of 

  

 65 








 
$15.0 million against the Company or any Significant Subsidiary that is not discharged, bonded or insured by a third Person if either an enforcement
proceeding thereon is commenced, or such judgment or decree remains outstanding for a period of 60 days and is not discharged, waived or stayed; or 
 (10) except as permitted by this Indenture, any Subsidiary Guaranty ceases to be in full force and effect (other than in accordance with the terms of such Subsidiary Guaranty) or any Subsidiary Guarantor denies or
disaffirms its obligations under its Subsidiary Guaranty. 
 The foregoing will constitute Events of Default whatever the reason for any such
Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 
 The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors.
The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 
 A Default under Sections 6.01(4) and (5) will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does
not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”. 
 The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any
Event of Default under Section 6.01(6) or (10) and any event which with the giving of notice or the lapse of time would become an Event of Default under Section 6.01(4), (5) or (9), its status and what action the Company is
taking or proposes to take with respect thereto. 
 SECTION 6.02. Acceleration. If an Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the outstanding Securities may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest
shall be due and payable immediately; provided, however, that so long as any Indebtedness permitted to be incurred pursuant to the Senior Credit Facilities is outstanding, such acceleration will not be effective until the earlier of
(1) the acceleration of such Indebtedness under the Senior Credit Facilities or (2) five Business Days after receipt by the Company of written notice of such acceleration. If an Event of Default specified in Section 6.01(7) or
(8) with respect to the Company occurs and is continuing, the principal of and interest on all of the outstanding Securities will ipso facto become and be immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. The Holders of a majority in aggregate principal amount of the then outstanding Securities by notice to the Trustee may, on behalf of the Holders of 

  

 66 








 
all of such Securities, waive any existing Default and its consequences under this Indenture, except a continuing Default in the payment of principal of and
premium, if any, or interest on any such Securities held by a non-consenting Holder. 
 SECTION 6.03. Other Remedies. In case an Event
of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or
security satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder of a Security may pursue any remedy with respect to this Indenture or
the Securities unless: 
 (1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

 (2) Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee to pursue the
remedy; 
 (3) such Holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or
expense; 
 (4) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of
security or indemnity; and 
 (5) Holders of a majority in principal amount of the outstanding Securities have not given the
Trustee a direction inconsistent with such request within such 60-day period. 
 The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder 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. 
 SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the
principal of or interest on a Security (b) a Default arising from the failure to redeem or purchase any Security when required pursuant to this Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be
amended without the consent of each Securityholder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. 
 SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction 

  

 67 








 
that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other
Securityholders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action
hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 SECTION 6.06. Limitation on Suits. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the Securities unless: 
 (1) the Holder gives to the
Trustee written notice stating that an Event of Default is continuing; 
 (2) the Holders of at least 25% in principal amount
of the Securities make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to the
Trustee security or indemnity satisfactory to it against any loss, liability or expense; 
 (4) the Trustee does not comply
with the request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) the Holders of
a majority in principal amount of the Securities do not give the Trustee a direction inconsistent with the request during such 60-day period. 
 A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. In the event that the Definitive Securities are not issued to any beneficial
owner promptly after the Registrar has received a request from the Holder of a Global Security to issue such Definitive Securities to such beneficial owner or its nominee, the Company expressly agrees and acknowledges, with respect to the right of
any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial holder’s Securities as if such
Definitive Securities had been issued. 
 SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of
this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 SECTION 6.08. Collection Suit
by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the 

  

 68 








 
whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

 SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on
behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any
other amounts due the Trustee under Section 7.07. 
 Priorities. If the Trustee collects any money or property
pursuant to this Article 6, it shall pay out the money or property in the following order: 
 FIRST: to the Trustee for
amounts due under Section 7.07; 
 SECOND: to holders of Senior Indebtedness of the Company and, if such money or
property has been collected from a Guarantor, to holders of Senior Indebtedness of such Guarantor, in each case to the extent required by Article 10 and 12; 
 THIRD: to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority
of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and 
 FOURTH: to the Company. 
 The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this
Section. At least 15 days before such record date, the Company shall mail to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid. 
 SECTION 6.10. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the
Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees, 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 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Securities. 
  

 69 








 SECTION 6.11. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so)
shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance
of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had been enacted. 
 Article VII 
 Trustee 
 SECTION 7.01. Duties of
Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would
exercise or use under the circumstances in the conduct of such Person’s own affairs. 
 (b) Except during the continuance
of an Event of Default: 
 (1) the Trustee undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming
to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical
calculations or other facts stated therein). 
 (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except that: 
 (1) this paragraph does not limit the
effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee shall not be liable for any error of judgment made
in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05. 
  

 70 








 (d) Every provision of this Indenture that in any way relates to the Trustee is subject
to paragraphs (a), (b) and (c) of this Section 7.01. 
 (e) The Trustee shall not be liable for interest
on any money received by it except as the Trustee may agree in writing with the Company. 
 (f) Money held in trust by the
Trustee need not be segregated from other funds except to the extent required by law. 
 (g) No provision of this Indenture
shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that
repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
 (h) Every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the provisions of the TIA. 
 SECTION 7.02. Rights of Trustee. (a) The Trustee may conclusively rely and shall be protected in acting or refraining on any document
believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel. 
 (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 
 (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within
its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence. 
 (e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. 
 (f) Whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other
evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate. 
  

 71 








 (g) The Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or direction. 
 (h) The Trustee shall not be bound
to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness 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. 
 (i) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the
Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 (j) The Trustee
shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office
of the Trustee, and such notice references the Securities and this Indenture. 
 (k) The rights, privileges, protections,
immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person
employed to act hereunder. 
 (l) The Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture. 
 SECTION 7.03.
Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not
Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 
 SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for
the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than
the Trustee’s certificate of authentication. 
  

 72 








 SECTION 7.05. Notice of Defaults. If a Default occurs, is continuing and is known to the Trustee,
the Trustee shall mail to each Securityholder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Security (including payments pursuant to the mandatory redemption
provisions of such Security, if any), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is not opposed to the interests of the Securityholders. 
 SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee shall mail to each Securityholder a brief report dated as of May 15 that complies with TIA § 313(a). The Trustee also shall comply with TIA
§ 313(b). 
 A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock
exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. 
 SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as the Company
and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s
agents, counsel, accountants and experts. The Company shall indemnify the Trustee or any predecessor Trustee and their agents against any and all loss, liability or expense (including attorneys’ fees) and taxes (other than taxes based upon,
measured by or determined by the income of the Trustee) incurred by it in connection with the administration of this trust and the performance of its duties hereunder including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section. The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of
such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, negligence or bad faith. 
 To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or
collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities. 
  

 73 








 The Company’s payment obligations pursuant to this Section shall survive the discharge of this
Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

 SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in
principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall 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 otherwise becomes incapable of acting. 
 If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists
in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The
retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities 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
Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 
 SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its


  

 74 








 
corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act
shall be the successor Trustee. 
 In case at the time such successor or successors by merger, conversion or consolidation to the Trustee
shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such
Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 
 SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee 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. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded
from the operation of TIA § 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 § 310(b)(1) are met. 
 SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall
comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated. 
 Article VIII 
 Discharge of Indenture;
Defeasance 
 SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a) When (1) the Company delivers to the
Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (2) all outstanding Securities have become due and payable, whether at maturity or on a redemption date as a result of the
mailing of a notice of redemption pursuant to Article 3 hereof and the Company irrevocably deposits or causes to be deposited with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to paragraph
(c) of this Section 8.01, cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the
cost and expense of the Company. 
  

 75 








 (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate
(1) all its obligations under the Securities and this Indenture (“legal defeasance option”) or (2) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.12 and the operation
of Sections 6.01(3), (with respect only to obligations under Section 4.10), 6.01(4), 6.01(5), 6.01(6), 6.01(7) (with respect to Significant Subsidiaries), 6.01(8) (with respect to Significant Subsidiaries), 6.01(9), and 6.01(10) and the
limitations contained in Section 5.01(a)(4) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. 
 If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect
thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.01(3) (with respect only to obligations under Section 4.10), 6.01(4),
6.01(5), 6.01(6), 6.01(7) (with respect only to Significant Subsidiaries), 6.01(8), 6.01(9), 6.01(10) or because of the failure of the Company to comply with Section 5.01(a)(4). If the Company exercises its legal defeasance option or its
covenant defeasance option, each Subsidiary Guarantor, if any, shall be released from all its obligations with respect to its Subsidiary Guaranty. 
 Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates. 
 (c) Notwithstanding Sections 8.01(a) and (b) above, the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and
in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive. 
 SECTION 8.02. Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if:

 (1) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment of
principal of and interest on the Securities to maturity or redemption, as the case may be; 
 (2) the Company delivers to the
Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any
deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be; 
 (3) 123 days pass after the deposit is made and during the 123-day period no Default specified in Section 6.01(7) or
(8) with respect to the Company occurs which is continuing at the end of the period; 
  

 76 








 (4) the deposit does not constitute a default under any other agreement binding on the
Company and is not prohibited by Article 10; 
 (5) the Company delivers to the Trustee an Opinion of Counsel to the effect
that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 
 (6) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal
Revenue Service a ruling, or (B) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the
Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the
case if such defeasance had not occurred; 
 (7) in the case of the covenant defeasance option, the Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and 
 (8) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities as contemplated by this Article 8 have been
complied with. 
 Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities
at a future date in accordance with Article 3. 
 SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money
or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the
payment of principal of and interest on the Securities. Money and securities so held in trust are not subject to Article 10. 
 SECTION 8.04.
Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time. 
 Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the
payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors. 
  

 77 








 SECTION 8.05. Indemnity for Government Obligations. The Company shall pay and shall indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. 
 SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with
this Article 8 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 Guarantor’s obligations
under this Indenture, each Guaranty and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. 
 Article IX 
 Amendments 
 SECTION 9.01. Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities

this Indenture relating to the transfer and legending of Securities; provided, however, that (a) compliance with this Indenture as so amended would not result in Securities being transferred in violation of the Securities Act or
any other applicable securities law and (b) such amendment does not materially and adversely affect the rights of Holders to transfer Securities; 
 (9) to conform the text of this Indenture or the Subsidiary Guaranties or the Securities to any provision of the “Description of the Notes” section of the Offering Circular to the extent that such provision
in such “Description of the Notes” was intended to be a verbatim recitation of a provision of this Indenture or the Subsidiary Guaranties or the Securities; or 
 (10) to provide for the issuance of Additional Securities in accordance with the limitations set forth in this Indenture as of the date of
this Indenture. 
 An amendment under this Section may not make any change that adversely affects the rights under Article 10 or 12 of any
holder of Senior Indebtedness of the Company or of a Subsidiary Guarantor then outstanding unless the holders of such Senior Indebtedness (or their Representative) consent to such change. 
 After an amendment under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 
 SECTION 9.02. With Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture, the Security Documents or the Securities with the written consent of the Holders of at
least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities) and any past default or compliance with any provisions may also be waived with the
consent of the Holders of at least a majority in principal amount of the Securities then outstanding. However, without the consent of each Securityholder affected thereby, an amendment or waiver may not: 
 (1) reduce the principal amount of Securities whose Holders must consent to an amendment; 
 (2) reduce the rate of or extend the time for payment of interest on any Security; 
  

 79 








 (3) reduce the principal of or change the Stated Maturity of any Security;

 (7) make any change in the amendment provisions which require each Holder’s consent or in the waiver provisions; 
 (8) make any change in the ranking or priority of any Security that would adversely affect the Holders; or 
 (9) make any change in, or release other than in accordance with this Indenture, any Subsidiary Guaranty that would adversely affect the Holders. 
 It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, but it shall be
sufficient if such consent approves the substance thereof. 
 An amendment under this Section may not make any change that adversely affects
the rights under Article 10 or 12 of any holder of Senior Indebtedness of the Company or of a Subsidiary Guarantor then outstanding unless the holders of such Senior Indebtedness (or their Representative) consent to such change. 
 After an amendment under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 
 SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture or the Securities shall comply with the TIA as then in effect. 
 SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder
and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver 

  

 80 








 
becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes effective upon the
execution of such amendment or waiver by the Trustee. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding
paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or
not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 
 SECTION 9.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an
appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new
Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment. 
 SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of
the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in
relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. Notwithstanding the foregoing, except as required by Section 4.12 hereof, neither an Opinion of
Counsel nor an Officer’s Certificate will be required for the Trustee to execute (i) any amendment or supplement adding a new Guarantor under this Indenture or (ii) a supplemental indenture to this Indenture, whereby Tube City IMS
Corporation assumes the obligations of the Company under this Indenture in connection with the merger of the Company with and into Tube City IMS Corporation. 
 SECTION 9.07. Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to
any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to all Holders and is paid to all Holders that so consent, waive or
agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

 Article X 
 Subordination 
 SECTION 10.01. Agreement To Subordinate. The Company agrees, and each
Securityholder by accepting a Security agrees, that the Indebtedness evidenced by the Securities is subordinated in right of payment, to the extent and in the manner provided in this Article 10, to the prior payment of all Senior Indebtedness of the
Company and that the subordination is for the benefit of and enforceable by the holders of such Senior Indebtedness. The Securities shall in all respects rank pari passu with all other Senior Subordinated Indebtedness of the Company
and only Indebtedness of the Company which is Senior Indebtedness of the Company shall rank senior to the Securities in accordance with the provisions set forth herein. All provisions of this Article 10 shall be subject to Section 10.12.

 SECTION 10.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of the Company upon a total or
partial liquidation or dissolution or reorganization of or similar proceeding relating to the Company or its property: 
 (1)
the holders of Senior Indebtedness of the Company shall be entitled to receive payment in full in cash of such Senior Indebtedness before the Holders are entitled to receive any payment; and 
 (2) until the Senior Indebtedness of the Company is paid in full in cash, any payment or distribution to which Holders would be entitled
but for the subordination provisions of this Indenture will be made to holders of such Senior Indebtedness as their interests may appear, except that Holders may receive and retain Permitted Junior Securities and payments from either of the trusts
described under Article 8; and 
 (3) if a distribution is made to Holders that, due to the subordination provisions, should
not have been made to them, such Holders are required to hold it in trust for the holders of Senior Indebtedness of the Company and pay it over to them as their interests may appear. 
 SECTION 10.03. Default on Senior Indebtedness of the Company. The Company shall not pay the principal of or interest on the Securities or make any
deposit pursuant to Section 8.01 and may not purchase, redeem or otherwise retire any Securities (collectively, “pay the Securities”) (except that Holders of Securities may receive and retain Permitted Junior Securities and
payments made from either of the trusts described under Article 8) if either of the following (a “Payment Default”) occurs (a) any Obligation on any Designated Senior Debt of the Company is not paid in full in cash when due; or
(b) any other default on Designated Senior Debt of the Company occurs and the maturity of such Designated Senior Debt is accelerated in accordance with its terms unless, in either case, the Payment Default has been cured or waived and any such
acceleration has been rescinded or such Designated Senior Debt has been paid in

full in cash; provided, however, that the Company shall be entitled to pay the Securities without regard to the foregoing if the Company and
the Trustee receive written notice approving such payment from the Representatives of all Designated Senior Debt with respect to which a Payment Default has occurred and is continuing. During the continuance of any default (other than a Payment
Default) with respect to any Designated Senior Debt of the Company pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of
any applicable grace periods, the Company shall not pay the Securities for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee of (with a copy to the Company) written notice (a “Blockage
Notice”) of such default from the Representative of such Designated Senior Debt specifying an election to effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment
Blockage Period is terminated (1) by written notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice is cured, waived or otherwise no
longer continuing; or (3) because such Designated Senior Debt has been discharged or repaid in full in cash. Notwithstanding the provisions described in the immediately preceding two sentences (but subject to the provisions contained in the
first sentence of this Section), unless the holders of such Designated Senior Debt or the Representative of such Designated Senior Debt shall have accelerated the maturity of such Designated Senior Debt, the Company shall be permitted to resume
payments on the Securities after termination of such Payment Blockage Period, subject to the provisions in the first sentence of this Section 10.03. The Securities shall not be subject to more than one Payment Blockage Period in any consecutive
360-day period, irrespective of the number of defaults with respect to Designated Senior Debt of the Company during such period. For purposes of this Section, no default or event of default which existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated Senior Debt of the Company initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the
Representative of such Designated Senior Debt, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. 
 SECTION 10.04. Acceleration of Payment of Securities. If payment of the Securities is accelerated because of an Event of Default, the Company or
the Trustee shall promptly notify the holders of the Designated Senior Debt of the Company (or their Representatives) of the acceleration. If any Designated Senior Debt of the Company is outstanding, the Company shall not pay the Securities until
five Business Days after the Representatives of all the issues of Designated Senior Debt of the Company receive notice of such acceleration and, thereafter, shall be entitled to pay the Securities only if this Article 10 otherwise permits
payment at that time. 
 SECTION 10.05. When Distribution Must Be Paid Over. If a distribution is made to Securityholders that because
of this Article 10 should not have been made to them, the Securityholders who receive the distribution shall hold it in trust for holders of Senior Indebtedness of the Company and pay it over to them or their Representatives as their interests may
appear. 
  

 83 








 SECTION 10.06. Subrogation. After all Senior Indebtedness of the Company is paid in full and until
the Securities are paid in full, Securityholders shall be subrogated to the rights of holders of such Senior Indebtedness to receive distributions applicable to such Senior Indebtedness. A distribution made under this Article 10 to holders of such
Senior Indebtedness which otherwise would have been made to Securityholders is not, as between the Company and Securityholders, a payment by the Company on such Senior Indebtedness. 
 SECTION 10.07. Relative Rights. This Article 10 defines the relative rights of Securityholders and holders of Senior Indebtedness of the Company.
Nothing in this Indenture shall: 
 (1) impair, as between the Company and Securityholders, the obligation of the Company,
which is absolute and unconditional, to pay principal of and interest on the Securities in accordance with their terms; or 
 (2) prevent the Trustee or any Securityholder from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness of the Company to receive distributions otherwise payable to Securityholders.

 SECTION 10.08. Subordination May Not Be Impaired by Company. No right of any holder of Senior Indebtedness of the Company to
enforce the subordination of the Indebtedness evidenced by the Securities shall be impaired by any act or failure to act by the Company or by its failure to comply with this Indenture. 
 SECTION 10.09. Rights of Trustee and Paying Agent. Notwithstanding Section 10.03, the Trustee or Paying Agent shall continue to make payments
on the Securities and shall not be charged with knowledge of the existence of facts that under this Article 10 would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer
of the Trustee receives notice satisfactory to it that such payments are prohibited by this Article 10. The Company, the Registrar or co-registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of the Company shall be
entitled to give the notice; provided, however, that, if an issue of Senior Indebtedness of the Company has a Representative, only the Representative shall be entitled to give the notice. 
 The Trustee in its individual or any other capacity shall be entitled to hold Senior Indebtedness of the Company with the same rights it would have if it
were not Trustee. The Registrar and co-registrar and the Paying Agent shall be entitled to do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 10 with respect to any Senior Indebtedness of the
Company which may at any time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article 7 shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 10 shall apply to claims
of, or payments to, the Trustee under or pursuant to Section 7.07. 
  

 84 








 SECTION 10.10. Distribution or Notice to Representative. Whenever any Person is to make a
distribution or give a notice to holders of Senior Indebtedness of the Company, such Person shall be entitled to make such distribution or give such notice to their Representative (if any). 
 SECTION 10.11. Article 10 Not To Prevent Events of Default or Limit Right To Accelerate. The failure to make a payment pursuant to the Securities
by reason of any provision in this Article 10 shall not be construed as preventing the occurrence of a Default. Nothing in this Article 10 shall have any effect on the right of the Securityholders or the Trustee to accelerate the maturity of the
Securities. 
 SECTION 10.12. Trust Moneys Not Subordinated. Notwithstanding anything contained herein to the contrary, payments from
money or the proceeds of U.S. Government Obligations held in trust under Article 8 by the Trustee for the payment of principal of and interest on the Securities shall not be subordinated to the prior payment of any Senior Indebtedness of the
Company or subject to the restrictions set forth in this Article 10, and none of the Securityholders shall be obligated to pay over any such amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of the
Company. 
 SECTION 10.13. Trustee Entitled To Rely. Upon any payment or distribution pursuant to this Article 10, the Trustee and the
Securityholders shall be entitled to rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 10.02 are pending, (b) upon a certificate of the liquidating
trustee or agent or other Person making such payment or distribution to the Trustee or to the Securityholders or (c) upon the Representatives of Senior Indebtedness of the Company for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of such Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 10. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Company to participate in any payment or distribution
pursuant to this Article 10, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 10, and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such Person
pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 10. 
 SECTION 10.14. Trustee To Effectuate Subordination. Each Securityholder by accepting a Security authorizes and directs the Trustee on his behalf
to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Securityholders and the holders of Senior Indebtedness of the Company as provided in this Article 10 and appoints the Trustee as
attorney-in-fact for any and all such purposes. 
  

 85 








 SECTION 10.15. Trustee Not Fiduciary for Holders of Senior Indebtedness of the Company. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Securityholders or the Company or any other
Person, money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article 10 or otherwise. 
 SECTION 10.16. Reliance by Holders of Senior Indebtedness of the Company on Subordination Provisions. Each Securityholder by accepting a Security acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was created or acquired before or after the issuance of the Securities, to acquire and continue to hold, or
to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness. 
 Article XI 
 Guaranties 
 SECTION 11.01. Guaranties. Each Guarantor hereby unconditionally and irrevocably guarantees, jointly and
severally, on a senior subordinated basis, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by
redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this
Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part,
without notice or further assent from such Guarantor and that such Guarantor will remain bound under this Article 11 notwithstanding any extension or renewal of any Guaranteed Obligation. 
 Each Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of
protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (1) the failure of any Holder or the Trustee to assert
any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Guarantor) under this Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof;
(3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (4) the release of any security held by any Holder or 

  

 86 








 
the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any
other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 11.06, any change in the ownership of such Guarantor. 
 Each Guarantor further agrees that its Guaranty herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had
by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations. 
 Each Guaranty is, to the extent and in the
manner set forth in Article 12, subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Senior Indebtedness of the Guarantor giving such Guaranty and each Guaranty
is made subject to such provisions of this Indenture. 
 Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06, the
obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense
of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each
Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver
or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any
extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity. 
 Each
Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Obligation is rescinded or must otherwise be
restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 
 In furtherance of the foregoing
and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the
same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee,
forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the
extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee. 
  

 87 








 Each Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any
Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations and all obligations to which the Guaranteed Obligations are subordinated as provided in Article 12. Each Guarantor further agrees that, as between it,
on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Guarantor’s Guaranty herein, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in
Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section. 
 Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section. 
 SECTION 11.02. Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of
the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 
 SECTION 11.03. Successors and
Assigns. This Article 11 shall be binding upon each Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by
any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this
Indenture. 
 SECTION 11.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising
any right, power or privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the
Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise. 
 SECTION 11.05. Modification. No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by
any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice
to or demand on any 

  

 88 








 
Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances. 
 SECTION 11.06. Release of Guarantor. A Guarantor will be released from its obligations under this Article 11 (other than any obligation that may have
arisen under Section 11.07): 
 (1) upon the sale or other disposition (including by way of consolidation or merger) of a
Guarantor, including the sale or disposition of Capital Stock of a Subsidiary Guarantor following which such Subsidiary Guarantor is no longer a Subsidiary, 
 (2) upon the sale or disposition of all or substantially all the assets of such Guarantor, 
 (3) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture,

 (4) at such time as such Guarantor does not have any Indebtedness outstanding that would have required such Guarantor to
enter into a Guaranty Agreement pursuant to Section 4.12 and the Company provides an Officers’ Certificate to the Trustee certifying that no such Indebtedness is outstanding and that the Company elects to have such Guarantor released from
this Article 11, or 
 (5) upon defeasance of the Securities pursuant to Article 8, or 
 (6) upon the full satisfaction of the Company’s obligations under this Indenture pursuant to Section 8.01(a) or otherwise in
accordance with the terms of this Indenture; 
 provided, however, that in the case of clauses (1) and (2) above, (i) such sale
or other disposition is made to a Person other than the Company or a Subsidiary of the Company, (ii) such sale or disposition is otherwise permitted by this Indenture and (iii) the Company provides an Officers’ Certificate to the
Trustee to the effect that the Company will comply with its obligations under Section 4.06. 
 At the request of the Company, the
Trustee shall execute and deliver an appropriate instrument evidencing such release. 
 SECTION 11.07. Contribution. Each Guarantor
that makes a payment under its Guaranty shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such
payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP. 
  

 89 








 Article XII 
 Subordination of Guaranties 
 SECTION 12.01. Agreement To Subordinate. Each Guarantor agrees, and
each Securityholder by accepting a Security agrees, that the Indebtedness evidenced by such Guarantor’s Guaranty is subordinated in right of payment, to the extent and in the manner provided in this Article 12, to the prior payment of all
Senior Indebtedness of such Guarantor and that the subordination is for the benefit of and enforceable by the holders of such Senior Indebtedness. The Obligations of a Guarantor shall in all respects rank pari passu with all other Senior
Subordinated Indebtedness of such Guarantor and only Senior Indebtedness of such Guarantor (including such Guarantor’s Guaranty of Senior Indebtedness of the Company) shall rank senior to the Obligations of such Guarantor in accordance with the
provisions set forth herein. 
 SECTION 12.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of
any Guarantor upon a total or partial liquidation or dissolution or reorganization of or similar proceeding relating to such Guarantor or its property: 
 (1) the holders of Senior Indebtedness of such Guarantor shall be entitled to receive payment in full in cash of such Senior Indebtedness before the Holders are entitled to receive any payment; and 
 (2) until the Senior Indebtedness of such Guarantor is paid in full in cash, any payment or distribution to which Holders would be
entitled but for the subordination provisions of this Indenture will be made to holders of such Senior Indebtedness as their interests may appear, except that Holders may receive and retain Permitted Junior Securities and payments from either of the
trusts described under Article 8; and 
 (3) if a distribution is made to Holders that, due to the subordination provisions,
should not have been made to them, such Holders are required to hold it in trust for the holders of Senior Indebtedness of such Guarantor and pay it over to them as their interests may appear. 
 SECTION 12.03. Default on Senior Indebtedness of Guarantor. No Guarantor shall make its Guaranty or purchase, redeem or otherwise retire or
defease any Securities (collectively, “pay its Guaranty”) (except that Holders of Securities may receive and retain Permitted Junior Securities and payments made from either of the trusts described in Article 8) if either of the
following (a “Payment Default”) occurs (a) any Obligation on any Designated Senior Debt of such Guarantor is not paid in full in cash when due; or (b) any other default on Designated Senior Debt of such Guarantor occurs
and the maturity of such Designated Senior Debt is accelerated in accordance with its terms unless, in either case, the Payment Default has been cured or waived and any such acceleration has been rescinded or such Designated Senior Debt has been
paid in full in cash; provided, however, that any Guarantor shall be entitled to pay its Guaranty 

  

 90 








 
without regard to the foregoing if such Guarantor and the Trustee receive written notice approving such payment from the Representatives of all Designated
Senior Debt with respect to which a Payment Default has occurred and is continuing. During the continuance of any default (other than a Payment Default) with respect to any Designated Senior Debt of such Guarantor pursuant to which the maturity
thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, such Guarantor shall not pay its Guaranty for a period (a
“Payment Blockage Period”) commencing upon the receipt by the Trustee of (with a copy to such Guarantor) written notice (a “Blockage Notice”) of such default from the Representative of such Designated Senior Debt
specifying an election to effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment Blockage Period is terminated (1) by written notice to the Trustee and such Guarantor
from the Person or Persons who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice is cured, waived or otherwise no longer continuing; or (3) because such Designated Senior Debt has been discharged or
repaid in full in cash. Notwithstanding the provisions described in the immediately preceding two sentences (but subject to the provisions contained in the first sentence of this Section), unless the holders of such Designated Senior Debt giving
such Payment Notice or the Representative of such Designated Senior Debt shall have accelerated the maturity of such Designated Senior Debt, any Guarantor shall be permitted to resume payments pursuant to its Guaranty after termination of such
Payment Blockage Period, subject to the provisions in the first sentence of this Section 12.03. No Guarantor shall be subject to more than one Payment Blockage Period in any consecutive 360-day period, irrespective of the number of defaults
with respect to Designated Senior Debt of such Guarantor during such period. For purposes of this Section, no default or event of default which existed or was continuing on the date of the commencement of any Payment Blockage Period with
respect to the Designated Senior Debt of such Guarantor initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior Debt, unless
such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. 
 SECTION 12.04.
Demand for Payment. If a demand for payment is made on a Guarantor pursuant to Article 11, the Trustee shall promptly notify the holders of the Designated Senior Debt of such Guarantor (or their Representatives) of such demand. If any
Designated Senior Debt of such Guarantor is outstanding, no Guarantor shall pay its Guaranty until five Business Days after the Representatives of all the issues of Designated Senior Debt of such Guarantor receive notice of such acceleration and,
thereafter, shall be entitled to pay its Guaranty only if this Article 12 otherwise permits payment at that time. 
 SECTION 12.05. When
Distribution Must Be Paid Over. If a distribution is made to Securityholders that because of this Article 12 should not have been made to them, the Securityholders who receive the distribution shall hold it in trust for holders of Senior
Indebtedness of the applicable Guarantor and pay it over to them or their Representatives as their interests may appear. 
  

 91 








 SECTION 12.06. Subrogation. After all Senior Indebtedness of a Guarantor is paid in full and until
the Securities are paid in full, Securityholders shall be subrogated to the rights of holders of such Senior Indebtedness to receive distributions applicable to Senior Indebtedness of such Guarantor. A distribution made under this Article 12 to
holders of such Senior Indebtedness which otherwise would have been made to Securityholders is not, as between the relevant Guarantor and Securityholders, a payment by such Guarantor on such Senior Indebtedness. 
 SECTION 12.07. Relative Rights. This Article 12 defines the relative rights of Securityholders and holders of Senior Indebtedness of a Guarantor.
Nothing in this Indenture shall: 
 (1) impair, as between a Guarantor and Securityholders, the obligation of such Guarantor,
which is absolute and unconditional, to pay its Guaranty to the extent set forth in Article 11; or 
 (2) prevent the Trustee
or any Securityholder from exercising its available remedies upon a default by such Guarantor under its Guaranty, subject to the rights of holders of Senior Indebtedness of such Guarantor to receive distributions otherwise payable to
Securityholders. 
 SECTION 12.08. Subordination May Not Be Impaired by Company. No right of any holder of Senior Indebtedness of any
Guarantor to enforce the subordination of the Guaranty of such Guarantor shall be impaired by any act or failure to act by such Guarantor or by its failure to comply with this Indenture. 
 SECTION 12.09. Rights of Trustee and Paying Agent. Notwithstanding Section 12.03, the Trustee or Paying Agent shall continue to make payments
on any Guaranty and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the Trustee receives
written notice satisfactory to it that such payments are prohibited by this Article 12. The Company, the relevant Guarantor, the Registrar or co-registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of such Guarantor shall
be entitled to give the notice; provided, however, that, if an issue of Senior Indebtedness of any Guarantor has a Representative, only the Representative shall be entitled to give the notice. 
 The Trustee in its individual or any other capacity shall be entitled to hold Senior Indebtedness of any Guarantor with the same rights it would have if
it were not Trustee. The Registrar and co-registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 12 with respect to any Senior Indebtedness of any Guarantor which
may at any time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article 7 shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 12 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.07. 
  

 92 








 SECTION 12.10. Distribution or Notice to Representative. Whenever any Person is to make a
distribution or give a notice to holders of Senior Indebtedness of any Guarantor, such Person shall be entitled to make such distribution or give such notice to their Representative (if any). 
 SECTION 12.11. Article 12 Not To Prevent Events of Default or Limit Right To Demand Payment. The failure to make a payment pursuant to a Guaranty
by reason of any provision in this Article 12 shall not be construed as preventing the occurrence of a Default. Nothing in this Article 12 shall have any effect on the right of the Securityholders or the Trustee to make a demand for payment on any
Guarantor pursuant to its Guaranty. 
 SECTION 12.12. Trustee Entitled To Rely. Upon any payment or distribution pursuant to this
Article 12, the Trustee and the Securityholders shall be entitled to rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 12.02 are pending, (b) upon a
certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Securityholders or (c) upon the Representatives for the holders of Senior Indebtedness of any Guarantor for the purpose
of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Indebtedness and other Indebtedness of such Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 12. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of any Guarantor to
participate in any payment or distribution pursuant to this Article 12, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness of such
Guarantor held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 12, and, if such evidence is not furnished, the
Trustee shall be entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions of actions
by the Trustee pursuant to this Article 12. 
 SECTION 12.13. Trustee To Effectuate Subordination. Each Securityholder by accepting a
Security authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Securityholders and the holders of Senior Indebtedness of any Guarantor as
provided in this Article 12 and appoints the Trustee as attorney-in-fact for any and all such purposes. 
 SECTION 12.14. Trustee Not
Fiduciary for Holders of Senior Indebtedness of Guarantor. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of any Guarantor and shall not be liable to any such holders if it shall mistakenly pay
over or distribute to Securityholders or the Company or 

  

 93 








 
any other Person, money or assets to which any holders of such Senior Indebtedness shall be entitled by virtue of this Article 12 or otherwise. 

SECTION 12.15. Reliance by Holders of Senior Indebtedness of Guarantors on Subordination Provisions. Each Securityholder by accepting a
Security acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of any Guarantor, whether such Senior Indebtedness was created or
acquired before or after the issuance of the Securities, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

Compliance Period, may be exchanged for interests in a Rule 144A Global Security, an IAI Global Security or the Permanent Regulation S Global

exemption under the Securities Act and (2) the transferor of the Regulation S Global Security or Rule 144A Global Security, as applicable, first delivers to the trustee a written certificate (substantially in the form of Exhibit 2) to the

collectively referred to herein as “Global Securities”. The aggregate principal amount of the Global Securities may from time to time be increased
or decreased by adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter provided. 
 (b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Security deposited with or on behalf of the Depository.

Depository for such Global Security or Global Securities or the nominee of such Depository and (b) shall be delivered by the Trustee to such Depository or pursuant to such Depository’s instructions or held by the Trustee as custodian for
the Depository. 
 Members of, or participants in, the Depository (“Agent Members”) shall have no rights
under this Indenture with respect to any Global Security held on their behalf by the Depository or by the Trustee as the custodian of the Depository or under such Global Security, and the Company, the Trustee and any agent of the Company or the
Trustee shall be entitled to treat the Depository as the absolute owner of such Global Security 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 the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the
exercise of the rights of a holder of a beneficial interest in any Global Security.

 (i) shall be duly endorsed or accompanied by a written
instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and

to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

 (A) if such Definitive Securities are being delivered to the Registrar by a Holder for registration in the name of such
Holder, without transfer, a certification from such Holder to that effect; or 
 (B) if such Definitive Securities are being
transferred to the Company, a certification to that effect; or

of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred. 
 (iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Security
may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or

procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Securities intended to ensure that such transfers comply with Rule 144A,

 (ii) Upon any sale or
transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer
Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such
sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security). 
 (iii) After a transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or
Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Private Exchange
Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case without restrictive
transfer legends, will be available to the transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such 

  

 10 








 
transferring Holder’s certificated Initial Security or Private Exchange Security or directions to transfer such Holder’s interest in the Global
Security, as applicable. 
 (iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities,
all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and
Exchange Securities in certificated or global form, in each case without the restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

 (v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such
Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange Securities in
global form with the global securities legend and the applicable restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange. 
 (f) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have either been
exchanged for Definitive Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Depository for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial
interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records
of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction. 
 (g) No Obligation of the Trustee. 
 (i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the records of
the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository)
of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be
given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository
subject to the applicable rules and procedures of the Depository. 

  

 11 








 
The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any
beneficial owners. 
 (ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial owners in any
Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof. 
 2.4 Definitive Securities. 
 (a) A Global Security deposited with the Depository or with the Trustee as Securities Custodian for the Depository pursuant to
Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such
transfer complies with Section 2.3 hereof and (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security and the Depository fails to appoint a successor depository or if at any
time such Depository ceases to be a “clearing agency” registered under the Exchange Act, in either case, and a successor depository is not appointed by the Company within 90 days of such notice, or (ii) an Event of Default has
occurred and is continuing or (iii) the Company, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under this Indenture. 
 (b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this Section 2.4 shall be surrendered by

deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations. Any portion of a Global Security transferred pursuant to this Section 2.4 shall be
executed, authenticated and delivered only in denominations of $2,000 principal amount and any integral multiples of $1,000 in excess of $2,000 and registered in such names as the Depository shall direct. Any Definitive Security delivered in
exchange for an interest in the Transfer Restricted Security shall, except as otherwise provided by Section 2.3(e) hereof, bear the applicable restricted securities legend and definitive securities legend set forth in Exhibit 1 hereto.

 (c) Subject to the provisions of Section 2.4(b) hereof, the registered Holder of a Global Security shall be entitled
to grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 
  

 12 








 (d) In the event of the occurrence of one of the events specified in Section 2.4(a)
hereof, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons. In the event that such Definitive Securities are not issued, the Company
expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to Section 6.06, the right of any beneficial owner of Securities to pursue such remedy with respect to the portion of the Global Security that
represents such beneficial owner’s Securities as if such Definitive Securities had been issued.

 [FORM OF REVERSE SIDE OF INITIAL SECURITY] 
 9 3/4% Senior Subordinated Note Due 2015 
  

	1.	Interest 

 Metal Services Merger Sub Corp., a
Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate
per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of $0.05 per week per $1,000 principal amount
of Initial Securities for the first 90-day period immediately following the occurrence of a Registration Default (increasing by an additional $0.05 per week per $1,000 principal amount of Initial Securities with respect to each subsequent 90-day
period until all Registration Defaults have been cured, up to a maximum additional interest rate of $0.30 per week per $1,000 principal amount of Initial Securities) from and including the date on which any such Registration Default shall occur to
but excluding the date on which all Registration Defaults have been cured. The Company will pay interest semiannually on February 1 and August 1 of each year, commencing August 1, 2007. Interest on the Securities will accrue from the
most recent date to which interest has been paid or, if no interest has been paid, from January 25, 2007. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at
the rate borne by this Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	Method of Payment 

 The Company will pay interest on
the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 15 or July 15 next preceding the interest payment date even if Securities are canceled after the
record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the
Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
  

 8 









	3.	Paying Agent and Registrar 

 Initially, The Bank of
New York, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar. 
  

	4.	Indenture 

 The Company issued the Securities under
an Indenture dated as of January 25, 2007 (“Indenture”), among the Company, the Guarantor named therein and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities
are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. 
 The
Securities are general unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to Section 2.14 of the Indenture. The Initial
Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains
covenants that limit the ability of the Company and its Restricted Subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; engage in transactions with affiliates;
create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of Restricted Subsidiaries of the Company; and consolidate, merge or transfer all or substantially all of its assets and the assets of its
subsidiaries. These covenants are subject to important exceptions and qualifications. 
  

	5.	Optional Redemption 

 Except as set forth below, the
Company shall not be entitled to redeem the Securities. 
 On and after February 1, 2011, the Company shall be entitled at its option to
redeem all or a portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued interest to the redemption date (subject
to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on February 1 of the years set forth below: 
  

				
	 Period
	  	Redemption
Price	 
	 2011
	  	104.875	%
	 2012
	  	102.438	%
	 2013 and thereafter
	  	100.000	%

  

 9 








 Prior to February 1, 2010, the Company shall be entitled at its option on one or more occasions to
redeem Securities (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) originally issued at a redemption
price (expressed as a percentage of principal amount) of 109.75%, plus accrued and unpaid interest to the redemption date, with the net cash proceeds from one or more Public Equity Offerings; provided, however, that (1) at least
65% of such aggregate principal amount of Securities (which includes Additional Securities, if any) remains outstanding immediately after the occurrence of each such redemption (other than Securities held, directly or indirectly, by the Company or
its Affiliates); and (2) each such redemption occurs within 90 days after the date of the related Public Equity Offering. 
 Prior to February 1, 2011, the Company shall be entitled at its option to redeem all, but not less than all, of the Securities at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as
of, and accrued and unpaid interest to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date). The Company shall cause notice of such redemption to be mailed
by first-class mail to each Holder’s registered address, not less than 30 nor more than 60 days prior to the redemption date. 
  

	6.	Notice of Redemption 

 Notice of redemption will be
mailed at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in
whole multiples of $1,000. The Company shall redeem Securities of $2,000 principal amount or less in whole and not in part. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be
redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for
redemption. 
  

	7.	Put Provisions 

 Upon a Change of Control, any
Holder of Securities will have the right to cause the Company to repurchase all or any part of the Securities of such Holder at a repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest to the
date of repurchase (subject to the right of Holders 

  

 10 








 
of record on the relevant record date to receive interest due on the related interest payment date) as provided in, and subject to the terms of, the
Indenture. 
  

	8.	Guaranty 

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

	9.	Subordination 

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

	10.	Denominations; Transfer; Exchange 

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

	11.	Persons Deemed Owners 

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

	12.	Unclaimed Money 

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

	13.	Discharge and Defeasance 

 Subject to certain
conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the 

  

 11 








 
Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity,
as the case may be. 
  

	14.	Amendment, Waiver 

 Subject to certain exceptions
set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company,
Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in
addition to or in place of certificated Securities, or to add guarantees with respect to the Securities, including Guaranties, or to secure the Securities, or to add additional covenants or surrender rights and powers conferred on the Company or the
Guarantors, or to comply with any requirement of the SEC in connection with qualifying the Indenture under the Act, or to make any change that does not adversely affect the rights of any Securityholder, or to make amendments to provisions of the
Indenture relating to the form, authentication, transfer and legending of the Securities or to conform the text of the Indenture or the Securities to any provision set forth in the Offering Circular relating to the Securities, or to provide for the
issuance of Additional Securities in accordance with the limitations set forth in the Indenture as of the date of the Indenture. 
  

	15.	Defaults and Remedies 

 Under the Indenture, Events
of Default include (a) default for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration
or otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company or any Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse
of time; (d) certain accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the Company, any Subsidiary or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds
$15 million; (e) certain events of bankruptcy or insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $15 million; and (g) certain
defaults with respect to Guaranties. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events
of bankruptcy or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default. 
 Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the 

  

 12 








 
Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice
is in the interest of the Holders.

 [FORM OF REVERSE SIDE OF [EXCHANGE] SECURITY 
 [OR PRIVATE EXCHANGE SECURITY]] 
 9 3/4% Senior Subordinated Note Due 2015 
  

	1.	Interest 

 Metal Services Merger Sub Corp., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to
pay interest on the principal amount of this Security at the rate per annum shown above[; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on
this Security at a rate of $0.05 per week per $1,000 principal amount of Initial Securities for the first 90-day period immediately following the occurrence of a Registration Default (increasing by an additional $0.05 per week per $1,000 principal
amount of Initial Securities with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of $0.30 per week per $1,000 principal amount of Initial Securities) from and
including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured].2 The Company will pay interest semiannually on February 1 and August 1 of each year, commencing August 1, 2007. Interest on the Securities will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from January 25, 2007. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this
Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	Method of Payment 

 The Company will pay interest on
the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 15 or July 15 next preceding the interest payment date even if Securities are canceled after the
record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified
by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by 
  


	 2
	 Insert if at the date of issuance of the Exchange Security or Private Exchange Security (as the case may
be) any Registration Default has occurred with respect to the related Initial Securities during the interest period in which such date of issuance occurs.

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

	3.	Paying Agent and Registrar 

 Initially, The Bank of
New York, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar. 
  

	4.	Indenture 

 The Company issued the Securities under
an Indenture dated as of January 25, 2007 (“Indenture”), among the Company, the Guarantor named therein and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. 
 The Securities are general unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to
Section 2.14 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes
under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Restricted Subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments;
engage in transactions with affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of Restricted Subsidiaries of the Company; and consolidate, merge or transfer all or substantially
all of its assets and the assets of its subsidiaries. These covenants are subject to important exceptions and qualifications. 
  

	5.	Optional Redemption 

 Except as set forth below, the
Company shall not be entitled to redeem the Securities. 
 On and after February 1, 2011, the Company shall be entitled at its option to
redeem all or a portion of the Securities upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on February 1 of the years set forth below: 
  

				
	 Period
	  	Redemption
Price	 
	 2011
	  	104.875	%
	 2012
	  	102.438	%
	 2013 and thereafter
	  	100.000	%

  

 6 








 Prior to February 1, 2010, the Company shall be entitled at its option on one or more occasions to
redeem Securities (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) originally issued at a redemption
price (expressed as a percentage of principal amount) of 109.75%, plus accrued and unpaid interest to the redemption date, with the net cash proceeds from one or more Public Equity Offerings; provided, however, that (1) at least
65% of such aggregate principal amount of Securities (which includes Additional Securities, if any) remains outstanding immediately after the occurrence of each such redemption (other than Securities held, directly or indirectly, by the Company or
its Affiliates); and (2) each such redemption occurs within 90 days after the date of the related Public Equity Offering. 
 Prior to February 1, 2011, the Company shall be entitled at its option to redeem all, but not less than all, of the Securities at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as
of, and accrued and unpaid interest to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date). The Company shall cause notice of such redemption to be mailed
by first-class mail to each Holder’s registered address, not less than 30 nor more than 60 days prior to the redemption date. 
  

	6.	Notice of Redemption 

 Notice of redemption will be
mailed at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in
whole multiples of $1,000. The Company shall redeem Securities of $2,000 principal amount or less in whole and not in part. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be
redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for
redemption. 
  

	7.	Put Provisions 

 Upon a Change of Control, any
Holder of Securities will have the right to cause the Company to repurchase all or any part of the Securities of such Holder at a 

  

 7 








 
repurchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest to the date of repurchase (subject to the
right of Holders of record on the relevant record date to receive interest due on the related interest payment date) as provided in, and subject to the terms of, the Indenture. 
  

	8.	Guaranty 

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

	9.	Subordination 

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

	10.	Denominations; Transfer; Exchange 

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

	11.	Persons Deemed Owners 

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

	12.	Unclaimed Money 

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

 8 









	13.	Discharge and Defeasance 

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

	14.	Amendment, Waiver 

 Subject to certain exceptions
set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company,
Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in
addition to or in place of certificated Securities, or to add guarantees with respect to the Securities, including Guaranties, or to secure the Securities, or to add additional covenants or surrender rights and powers conferred on the Company or the
Guarantors, or to comply with any requirement of the SEC in connection with qualifying the Indenture under the Act, or to make any change that does not adversely affect the rights of any Securityholder, or to make amendments to provisions of the
Indenture relating to the form, authentication, transfer and legending of the Securities or to conform the text of the Indenture or the Securities to any provision set forth in the Offering Circular relating to the Securities, or to provide for the
issuance of Additional Securities in accordance with the limitations set forth in the Indenture as of the date of the Indenture. 
  

	15.	Defaults and Remedies 

 Under the Indenture, Events
of Default include (a) default for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption pursuant to paragraph 5 of the Securities, upon acceleration
or otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company or any Guarantor to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse
of time; (d) certain accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the Company, any Subsidiary or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds
$15 million; (e) certain events of bankruptcy or insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $15 million; and (g) certain
defaults with respect to Guaranties. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events
of bankruptcy or 

  

 9 








 
insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default.

 Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 
  

	16.	Trustee Dealings with the Company 

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

	17.	No Recourse Against Others 

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

	18.	Authentication 

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

	19.	Abbreviations 

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

	20.	CUSIP Numbers 

 Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of 

  

 10 








 
redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as
contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
  

	21.	[Holders’ Compliance with Registration Rights Agreement. 

 Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the
Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.] 3

 The undersigned represents and warrants to you that: 
 1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as
amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities
not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and 








 
business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to
the Securities in the normal course of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment. 
 2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf
of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is two years after the later of the date of original issue and the last date on which the Company or any
affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (i) to the Company, (ii) in the United States to a person whom the seller reasonably
believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A, (iii) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act that is an institutional accredited investor purchasing for its own account or for the account of an institutional accredited investor, in each case in a minimum principal amount of the Securities of $250,000, (iv) outside the
United States in a transaction complying with the provisions of Rule 904 under the Securities Act, (v) pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if available) or (vi) pursuant to an effective
registration statement under the Securities Act, in each of cases (i) through (vi) subject to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or
their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be
made pursuant to clause (iii) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among
other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Securities for investment purposes and
not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities
pursuant to clause (iii), (iv) or (v) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Company and the Trustee.
