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

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 EBITDA resulting therefrom) had occurred on the first day of the reference period. If since the beginning of such period any Person (that
subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted 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. 
 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. Any such pro forma calculation may include, without duplication, adjustments appropriate to reflect
(1) operating expense reductions and other operating improvements or synergies reasonably expected to result from the applicable event and (2) all adjustments of the nature used in connection with the calculation of “Adjusted
EBITDA” as set forth in the Offering Memorandum to the extent such adjustments, without duplication, continue to be applicable to the reference period. 

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 Financing 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 Financing 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.

Company shall have no obligation to do so. Such record date shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If
such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and
for that purpose the Outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than eleven months after the record date. Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and
the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Company or any Guarantor in reliance thereon,
whether or not notation of such action is made upon such Note. 
 Without limiting the foregoing, a Holder entitled to take any action
hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part
of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such
different part. 
 Without limiting the generality of the foregoing, a Holder, including the Depository that is the Holder of a Global Note,
may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and the Depository that
is the Holder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such depositary’s standing instructions and customary practices. 

The Company may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any Global Note held by
the Depository entitled under the procedures of such depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture
to be made, given or taken by Holders. 
 SECTION 106. Notices, Etc., to Trustee, Company and Any Guarantor. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 

(1) the Trustee by any Holder or by the Company or any Guarantor shall be sufficient for every purpose hereunder if made,
given, furnished or filed in writing (which may be via facsimile, .pdf transmission or other electronic means) to or with the Trustee at U.S. Bank National Association, 535 Griswold Street, Suite 550, Detroit, MI 48226, Attn: Global Corporate

SECTION 107. Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders by the Company or the Trustee,
such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and either (1) mailed, first-class postage prepaid, to each Holder affected by such event, at his 

  
 -37- 








 
address as it appears in the Note Register, within the time prescribed for the giving of such notice or (2) in the case of Notes held through the Depository, sent or transmitted to Holders
in any manner that is in accordance with the procedures of the Depository. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect
the sufficiency of such notice with respect to other Holders. Notices given by publication or electronic delivery shall be deemed given on the first date on which publication or electronic delivery is made and notices given by first-class mail,
postage prepaid, shall be deemed given five calendar days after mailing. 
 In case by reason of the suspension of or irregularities in
regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder. 
 Where this
Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 

Notwithstanding anything herein to the contrary, where this Indenture provides for notice in any manner, such notice may be sent or
transmitted to Holders in any manner that is in accordance with the procedures of the Depository and shall be deemed to be a sufficient giving of such notice for every purpose hereunder.

agreements of the Trustee in this Indenture shall bind its successors. All agreements of each Guarantor in this Indenture shall bind its successors, except as otherwise provided in Section 1208 hereof. 

SECTION 110. Separability Clause. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 111.
Benefits of Indenture. Nothing in this Indenture or in the Notes or in any other Notes Document, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Note Registrar and their successors hereunder
and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 112. Governing Law; Waiver

the State of New York. 
 (b) EACH OF THE COMPANY, THE GUARANTORS, THE TRUSTEE, THE COLLATERAL AGENT, THE PAYING AGENT, AND THE NOTE
REGISTRAR HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES, THE NOTES GUARANTEES OR THE TRANSACTIONS
CONTEMPLATED HEREBY. 
 SECTION 113. Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity
or Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Notes) payment of principal (or premium, if any) or interest need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date, or at the Stated Maturity or Maturity; provided that no interest shall accrue for purposes of such payment for the period from
and after such Interest Payment Date, Redemption Date, Stated Maturity or Maturity, as the case may be.

 SECTION 114. No Personal Liability of Directors, Officers, Employees and Stockholders. No
past, present or future director, officer, employee, incorporator or stockholder of the Company or any Guarantor (other than in the case of stockholders of any Guarantor, the Company or another Guarantor) or any of their parent companies shall have
any liability for any obligations of the Company or the Guarantors under the Notes, the Notes Guarantees and this Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Notes Guarantees. 

SECTION 115. Limited Condition Transaction. Notwithstanding anything to the contrary herein or in any other Notes Document, in
connection with any action required to be taken in connection with a Limited Condition Transaction, for purposes of: (i) calculating the Consolidated Priority Secured Debt Ratio, Consolidated Secured Debt Ratio, Consolidated Total Debt Ratio,
the Fixed Charge Coverage Ratio and other financial calculations; (ii) determining compliance with Defaults or Events of Defaults; or (iii) testing availability under covenant baskets set forth in this Indenture (including covenant baskets
measured as a percentage of Consolidated Total Assets), in each case, at the option of the Company (the Company’s election to exercise such option in connection with any Limited Condition Transaction, an “LCT Election”), the
date of determination shall be deemed to be the date the definitive agreement for such Limited Condition Transaction is entered into (the “LCT Test Date”), and if, after giving pro forma effect to the Limited Condition Transaction
and the other transactions required to be entered into in connection therewith (including any incurrence or repayment of Indebtedness and the use of proceeds thereof) as if they had occurred at the beginning of the most recent test period ending
prior to the LCT Test Date, the Company could have taken such action on the relevant LCT Test Date in compliance with such ratio, test or basket, such ratio, test or basket shall be deemed to have been complied with; provided that
availability under any ratio and the determination of whether the relevant condition is satisfied may in any event be recalculated, at the option of the Company, on the closing date of the Limited Condition Transaction. For the avoidance of doubt,
if the Company has made an LCT Election and any of the ratios, tests or baskets for which compliance was determined or tested as of the LCT Test Date are exceeded as a result of fluctuations in any such ratio, test or basket, including due to
fluctuations in EBITDA of the Company or the Person subject to such Limited Condition Transaction, at or prior to the consummation of the relevant transaction or action, such baskets, tests or ratios will not be deemed to have been exceeded as a
result of such fluctuations. If the Company has made an LCT Election for any Limited Condition Transaction, then in connection with any calculation of any ratio, test or basket availability with respect to any transaction required to be entered into
in connection with such Limited Condition Transaction following the relevant LCT Test Date and prior to the earlier of (i) the date on which such Limited Condition Transaction is consummated or (ii) the date that the definitive agreement
for such Limited Condition Transaction is terminated or expires without consummation of such Limited Condition Transaction, for purposes of determining whether any such required transaction is permitted under this Indenture or any other Notes
Document, any such ratio, test or basket shall be calculated on a pro forma basis assuming such Limited Condition Transaction and other transactions in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof)
have been consummated. If the Company has made an LCT Election for any Limited Condition Transaction, then in connection with any calculation of any other ratio, test or basket availability with respect to the incurrence of Indebtedness or Liens,
the making of Restricted Payments (subject to the proviso at the end of this sentence), the making of any Permitted Investment, mergers, the conveyance, lease or other transfer of all or substantially all of the assets of the Company, the
prepayment, redemption, purchase, defeasance or other satisfaction of Indebtedness, or the designation of an Unrestricted Subsidiary, in each case, not required to be entered into in connection with the applicable Limited Condition Transaction (a
“Subsequent Transaction”) following the relevant LCT Test Date and prior to the earlier of (x) the date on which such Limited Condition Transaction is consummated or (y) the date that the definitive agreement for such
Limited Condition Transaction is terminated or expires without consummation of such Limited Condition Transaction (or the date on which the Company demonstrates to the Trustee that it has elected not to pursue such Limited Condition Transaction),
for purposes of determining whether such Subsequent Transaction is permitted under this Indenture, any such ratio, test or basket shall be required to be satisfied on a pro forma basis assuming such Limited Condition Transaction and other
transactions required to be entered into in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) have been consummated; provided, in the case of Restricted Payments (other than Investments) such
ratio tests and baskets will be tested both as if such transaction had been consummated and as if such transaction had not been consummated.

 SECTION 116. Counterparts. This Indenture and any other Notes Document may be executed in
any number of counterparts, each of which shall be original; but such counterparts shall together constitute but one and the same instrument. One signed copy is enough to prove this Indenture. The exchange of copies of this Indenture and any other
Notes Document and of signature pages by facsimile, .pdf transmission or other electronic means shall constitute effective execution and delivery of this Indenture and any other Notes Document for all purposes. Signatures of the parties hereto
transmitted by facsimile or .pdf transmission or other electronic means shall be deemed to be their original signatures for all purposes.

 In case the Company, pursuant to Article Eight of this Indenture, shall, in one or more related

purposes of the provisions of this Indenture relating to transfer and exchange as a separate class that does not trade fungibly with Notes that have differing treatment under U.S. Federal income tax law and will be assigned a different CUSIP or
other identification number). Any Additional Notes shall be issued pursuant to a supplemental indenture to this Indenture. 
 The Notes
shall be known and designated as the “10.750% Senior Secured Junior Priority Notes due 2023” of the Company. The Stated Maturity of the Notes shall be July 15, 2023. The Notes shall bear interest at the rate set forth below from
June 25, 2018, or from the most recent Interest Payment Date to which interest has been paid or duly provided for. Interest on the Notes is payable on January 15, 2019 and semi-annually thereafter on January 15 and July 15 in
each year and at said Stated Maturity, until the principal thereof is paid or duly provided for and to the Person in whose name the Note (or any Predecessor Note) is registered at the close of business on the January 1 and July 1
immediately preceding such Interest Payment Date (each, a “Regular Record Date”). 
 The principal of (and premium, if any)
and interest on the Notes shall be payable at the office or agency of the Company maintained for such purpose in the City of New York or, at the option of the Company, payments of interest may be made by check mailed to the Holders of the Notes at
their respective addresses set forth in the Note Register of Holders; provided that all payments of principal, premium, if any, and interest, if any, with respect to Notes represented by one or more global notes registered in the name of or
held by the Depository or its nominee shall be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof. 

Holders shall have the right to require the Company to purchase their Notes, in whole or in part, in the event of a Change of Control pursuant
to Section 1017. The Notes shall be subject to repurchase pursuant to an Asset Sale Offer as provided in Section 1018 and a Loss Proceeds Offer as provided in Section 1020. 

The Notes shall be redeemable as provided in Article Eleven of this Indenture and Paragraph 6 of the Notes. 

The due and punctual payment of principal of, premium, if any, and interest on the Notes payable by the Company is irrevocably unconditionally
guaranteed, to the extent set forth herein, by each of the Guarantors.

 SECTION 302. Denominations. The Notes shall be issuable only in registered form without
coupons and only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. 
 SECTION 303. Temporary Notes.
Pending the preparation of definitive Notes, the Company may execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced,
in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may
determine, as conclusively evidenced by their execution of such Notes. 
 If temporary Notes are issued, the Company shall cause definitive
Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for
such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes. 

SECTION 304. Note Registrar; Paying Agent; Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate
Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”) in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or any other form capable of being converted into written form within a
reasonable time. At all reasonable times, the Note Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as note registrar (the “Note Registrar”) for the purpose of registering Notes and
transfers of Notes as herein provided. The Trustee is hereby initially appointed to act as the Paying Agent and to act as Notes Custodian with respect to the Global Notes. 

Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 1002, the
Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount. 

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is
entitled to receive. 
 All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Note Registrar)
be duly endorsed, or be accompanied by written instruments of transfer, in form satisfactory to the Company and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Company may require payment of a
sum sufficient to cover any taxes, fees or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Sections 202, 303, 906, 1017, 1018, 1020 or 1108 not
involving any transfer. 
 SECTION 305. Mutilated, Destroyed, Lost and Stolen Notes. If (1) any mutilated Note is surrendered to
the Trustee or (2) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company and the Trustee such security or indemnity as may be 

  
 -42- 








 
required to protect the Company, the Trustee, any agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced, then, in the absence of notice to the Company
or the Trustee that such Note has been acquired by a Protected Purchaser (as defined in Section 8-303 of the UCC) (a “Protected Purchaser”), the Company shall execute and upon Company
Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Note, pay such Note. 
 Upon the issuance of any new Note under this Section 305, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in replacing a Note. 

Every new Note issued pursuant to this Section 305 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company and each Guarantor, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder. 
 The provisions of this Section 305 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 

SECTION 306. Payment of Interest; Interest Rights Preserved. 

(a) Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 1002;
provided, however, that, subject to Section 301 hereof, each installment of interest may at the Company’s option be paid by (1) mailing a check for such interest, payable to or upon the written order of the Person
entitled thereto pursuant to Section 307, to the address of such Person as it appears in the Note Register or (2) transfer to an account located in the United States maintained by the payee. 

(b) Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith
cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and
interest thereon herein collectively called “Defaulted Interest”) may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their
respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10
days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor to be given in the manner provided for in Section 107, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no
longer be payable pursuant to the following clause (2). 

  
 -43- 








 (2) The Company may make payment of any Defaulted Interest in any other lawful
manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment
pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 (c) Subject to the foregoing provisions of
this Section 306, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other
Note. 
 SECTION 307. Persons Deemed Owners. Prior to the due presentment of a Note for registration of transfer, the Company, any
Guarantor, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to
Section 306) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 

SECTION 308. Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to
any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold, and all Notes so
delivered shall be promptly cancelled by the Trustee. If the Company shall so acquire any of the Notes, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the
same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section 308, except as expressly permitted by this Indenture. All cancelled Notes held
by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures (subject to the record retention requirements of the Exchange Act). Certification of the destruction of all cancelled Notes shall be delivered to the
Company by the Trustee. The Trustee shall maintain a record of all cancelled Notes. The Trustee shall provide the Company a list of all Notes that have been cancelled from time to time as requested by the Company. 

SECTION 309. Computation of Interest. Interest on the Notes shall be computed on the basis of a
360-day year of twelve 30-day months. 
 SECTION 310.
Transfer and Exchange. The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Note Registrar or a
co-registrar with a request to register a transfer, the Note Registrar shall register the transfer as requested if the requirements of this Indenture and
Section 8-401(a) of the UCC are met. When Notes are presented to the Note Registrar or a co-registrar with a request to exchange them for an equal principal amount
of Notes of other denominations, the Note Registrar shall make the exchange as requested if the same requirements are met. 
 The Company
shall not be required, and without the prior written consent of the Company, the Note Registrar shall not be required, to register the transfer of or exchange of any Note (i) during a period beginning at the opening of business 15 days before
sending a notice of redemption of Notes and ending at the close of business on the day such notice is sent, (ii) selected for redemption in whole or in part, (iii) that has been tendered in a Change of Control Offer or (iv) beginning
at the opening of business on any record date and ending on the close of business on the related Interest Payment Date. 
 SECTION 311.
CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case, if then generally in use) in addition to serial numbers, and, if so, the Trustee shall use such
“CUSIP” numbers, ISINs and “Common Code” numbers in addition to serial numbers in 

  
 -44- 








 
notices of redemption, repurchase or other notices to Holders as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of
such “CUSIP” numbers, ISINs and “Common Code” numbers either as printed on the Notes or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers
printed on the Notes, and any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers, ISINs and
“Common Code” numbers applicable to the Notes. 
 SECTION 312. Issuance of Additional Notes. The Company may, subject to
Sections 1011 and 1012 of this Indenture, issue additional Notes having identical terms and conditions to the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, the issue price and the date from which interest
first begins to accrue (the “Additional Notes”). The Initial Notes issued on the Issue Date and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture (except that any
series of Notes that is not fungible with the Initial Notes for U.S. Federal income tax purposes may be treated for purposes of the provisions of this Indenture relating to transfer and exchange as a separate class that does not trade fungibly with
Notes that have differing treatment under U.S. Federal income tax law and will be assigned a different CUSIP or other identification number). 

Notwithstanding anything else herein, with respect to any Additional Notes issued subsequent to the date of this Indenture, when the context
requires, all provisions of this Indenture, subject to Sections 1011 and 1012 of this Indenture, shall be construed and interpreted to permit the issuance of such Additional Notes and to allow such Additional Notes to become fungible and
interchangeable with the Initial Notes originally issued under this Indenture. 
 ARTICLE FOUR 

SATISFACTION AND DISCHARGE 

SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request and at the Company’s expense cease
to be of further effect as to all Notes issued hereunder and then Outstanding, and all Liens on the Collateral granted under the Security Documents shall be automatically released (except as set forth in the last paragraph of this Section and as to
surviving rights of registration of transfer or exchange of Notes expressly provided for herein or pursuant hereto), and the Trustee and the Collateral Agent, at the expense of the Company, shall execute proper instruments acknowledging satisfaction
and discharge of this Indenture when: 
 (1) either: 

(A) all Notes theretofore authenticated and delivered (other than (i) Notes which have been destroyed, lost or stolen and
which have been replaced or paid as provided in Section 305 and (ii) Notes for whose payment money has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by the Company and thereafter
repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 

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

(i) have become due and payable by reason of the making of a notice of redemption pursuant to Section 1106 or otherwise,
or 
 (ii) shall become due and payable at their Stated Maturity within one year, or 

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice
of redemption by the Trustee in the name, and at the expense, of the Company, 

  
 -45- 








 and the Company or any Guarantor, in the case of (i), (ii) or (iii) of this subclause (B),
has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination
thereof, in such amounts as shall be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if
any, and accrued interest to the date of maturity or redemption, as the case may be; 
 (2) no Default (other than that
resulting from borrowing funds to be applied to make such deposit and the granting of Liens in connection therewith) with respect to this Indenture or the Notes issued hereunder shall have occurred and be continuing on the date of such deposit or
shall occur as a result of such deposit and such deposit shall not result in a breach or violation of, or constitute a default under, any Credit Facility, the 6% Senior Subordinated Debt Documents, the 6% Senior Subordinated Exchangeable Notes or
any other material agreement or instrument (other than this Indenture) to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 

(3) the Company has paid or caused to be paid all sums payable by it under this Indenture and the Company and the Guarantors
have paid or caused to be paid all sums payable to the Trustee and/or the Collateral Agent under the Security Documents; 

(4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward
the payment of such Notes at Maturity or the Redemption Date, as the case may be; and 
 (5) the Company has delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein to the satisfaction and discharge of this Indenture have been satisfied. 

Notwithstanding the satisfaction and discharge of this Indenture, if money or Government Securities shall have been deposited with the Trustee
pursuant to subclause (B) of clause (1) of this Section 401, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive such satisfaction and discharge. In addition, nothing in this
Section 401 shall be deemed to discharge the obligations of the Company and the Guarantors to the Trustee under Section 607, the obligations of the Company and the Guarantors to the Collateral Agent under Section 1502(a) and the
obligations of the Company to any Authenticating Agent under Section 612 that, in each case, by their terms, survive the satisfaction and discharge of this Indenture. 

SECTION 402. Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money or Government
Securities deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including
the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money or Government Securities has been deposited with the Trustee,
but such money or Government Securities need not be segregated from other funds except to the extent required by law. 
 If the Trustee or
Paying Agent is unable to apply any money or Government Securities in accordance with Section 401 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 any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 until such time as the Trustee or
Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 401; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

Indebtedness or guarantee now exists or is created after the Issue Date, if both: 
 (A) such default either: 

(i) results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to
any applicable grace periods); or

Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity; and 

(B) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for

the Security Documents or (B) to the extent any such loss is covered by title insurance for which the insurer has not denied coverage. 

SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

(a) If any Event of Default (other than an Event of Default specified in Section 501(6) with respect to the Company) occurs and is
continuing under this Indenture, the Trustee or the Holders of at least 30% in principal amount of the Outstanding Notes issued under this Indenture may declare the principal, premium, if any, interest and any other monetary Obligations on all the
Outstanding Notes issued under this Indenture to be due and payable immediately by a notice in writing to the Company (and to the Trustee and the Collateral Agent if given by the Holders). 

  
 -48- 








 (b) Upon the effectiveness of such declaration, such principal of and premium, if any, and
interest on the Notes shall be due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in Section 501(6) with respect to the Company occurs and is continuing, then the principal amount of all Outstanding
Notes shall ipso facto become and be immediately due and payable without any notice, declaration or other act on the part of the Trustee or any Holder. 

(c) At any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter provided in this Article Five, the Holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its
consequences if: 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay: 

(A) all overdue interest on all Outstanding Notes, 

(B) all unpaid principal of (and premium, if any, on) any Outstanding Notes which has become due otherwise than by such
declaration of acceleration, and interest on such unpaid principal at the rate borne by the Notes,

payment of such interest is lawful, interest on overdue interest at the rate borne by the Notes, and 
 (D) all sums paid or
advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

(2) Events of Default, other than the non-payment of amounts of principal of (or
premium, if any, on) or interest on Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 

No such rescission shall affect any subsequent default or impair any right consequent thereon. 

(d) Notwithstanding the preceding clause (c), in the event of any Event of Default specified in Section 501(4) above, such Event of
Default and all consequences thereof (excluding any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if, within 30 days after such Event of Default arose, 

(1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged, or 

(2) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such
Event of Default, or 
 (3) the default that is the basis for such Event of Default has been cured. 

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. If an Event of Default specified in Section 501(1)
or (2) occurs and is continuing, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums due hereunder pursuant to this Article Five and unpaid, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. The Trustee may prosecute such proceeding
to judgment or final decree and may enforce the same against the Company, any Guarantor or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company,
any Guarantor or any other obligor upon the Notes, wherever situated. 

  
 -49- 








 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders under this Indenture and the Notes Guarantees by the judicial proceedings discussed above as the Trustee shall deem necessary to protect and enforce any such rights, including seeking
recourse against any Guarantor. 
 SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor, including any Guarantor, upon the Notes or the property of the Company or of such
other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, 

(1) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect
of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and of the Holders allowed in such judicial proceeding, and 
 (2) to collect, receive and distribute any moneys
or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay
the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

SECTION 505. Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes
may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee
of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in
respect of which such judgment has been recovered. 
 SECTION 506. Application of Money Collected. Subject to the terms of the
Security Documents, any money or property collected by the Trustee pursuant to this Article Five, together with any amounts received from the Collateral Agent, shall be applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee and the Collateral Agent, and their agents and attorneys, under
Section 607, whether arising under this Indenture or the Security Documents; 
 SECOND: To the payment of the
amounts then due and unpaid for principal of (and premium, if any) and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts
due and payable on such Notes for principal (and premium, if any) and interest, respectively; and 

  
 -50- 








 THIRD: The balance, if any, to the Company or as a court of competent
jurisdiction may direct in writing; provided that all sums due and owing to the Holders, the Collateral Agent and the Trustee have been paid in full as required by this Indenture and the Security Documents. 

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 506. 

SECTION 507. Limitation on Suits. Subject to Section 508 and compliance with the Intercreditor Agreements and any other
intercreditor agreement entered into in accordance with the terms of this Indenture, no Holder of any Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless: 
 (1) such Holder has previously given the Trustee and the Collateral
Agent notice that an Event of Default is continuing; 
 (2) Holders of at least 30% in principal amount of the Outstanding
Notes have requested the Trustee and the Collateral Agent to pursue the remedy; 
 (3) such Holders have offered the Trustee
and the Collateral Agent reasonable security or indemnity against any loss, liability or expense; 
 (4) the Trustee and the
Collateral Agent have 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 Notes have not given the Trustee or the Collateral Agent a
direction inconsistent with such request within such 60-day period, 
 it being understood and intended that no one
or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture, the Security Documents or the Notes Guarantees to affect, disturb or prejudice the rights of any other Holders, or to
obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, the Security Documents or the Notes Guarantees, except in the manner herein provided and for the equal and ratable benefit of all
the Holders (it being further understood that the Trustee and the Collateral Agent do not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders). 

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this
Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Eleven) and in such Note of the principal of (and premium, if any) and (subject to
Section 306) interest on such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date), and to institute suit for the enforcement of any such payment on or after such respective
dates, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 509. Restoration of Rights and Remedies.
If the Trustee, the Collateral Agent or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture, the Security Documents or the Notes Guarantees and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee, to the Collateral Agent or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, any Guarantor, any other obligor of the Notes, the
Trustee, the Collateral Agent and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee, the Collateral Agent and the Holders shall continue as though no
such proceeding had been instituted. 

  
 -51- 








 SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 305, no right or remedy herein conferred upon or reserved to the Trustee, the Collateral Agent or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

SECTION 511. Delay or Omission Not Waiver. No delay or omission of the Trustee, the Collateral Agent or of any Holder of any Note to
exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article Five or by law to the
Trustee, the Collateral Agent or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee, the Collateral Agent or by the Holders, as the case may be. 

SECTION 512. Control by Holders. Subject to the terms of the Security Documents and the terms of Article Six and Article Fifteen
hereof, the Holders of not less than a majority in principal amount of the Outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Collateral Agent, or
exercising any trust or power conferred on the Trustee or the Collateral Agent; provided that: 
 (1) such direction
shall not be in conflict with any rule of law or with this Indenture or with the Security Documents; and 
 (2) the Trustee
and the Collateral Agent may take any other action deemed proper by the Trustee or the Collateral Agent, as applicable, which is not inconsistent with such direction. 

Notwithstanding the foregoing and notwithstanding the terms of the Security Documents, neither the Trustee nor the Collateral Agent need take
any action which might involve it in personal liability or which would be unduly prejudicial to the Holders not consenting as set forth above. 

Without such direction, neither the Trustee nor the Collateral Agent will be obligated to act upon directions purported to be delivered to it
by any other Person, to foreclose upon or otherwise enforce any Lien or to take any other action whatsoever with regard to any or all of the Security Documents, the Lien created thereby or the Collateral. 

SECTION 513. Waiver of Default. Subject to Sections 508 and 902, the Holders of not less than a majority in principal amount of the
Outstanding Notes may on behalf of the Holders of all such Notes waive any Default hereunder and its consequences, except a continuing Default or Event of Default (1) in respect of the payment of interest on, premium, if any, or the principal
of any such Note held by a non-consenting Holder or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Note affected. 
 Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be
deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

SECTION 514. Waiver of Stay or Extension Laws. Each of the Company, the Guarantors and any other obligor on the Notes covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force that
would prohibit or forgive the Company or a Guarantor from paying any portion of the principal of, and premium, if any, and interest on the Notes. 

  
 -52- 








 SECTION 515. Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee or the Collateral Agent for any action taken or omitted by it as a Trustee or as a Collateral Agent, a court in its discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section 515 does not apply to a suit by the Trustee, a suit by the Collateral Agent, a suit by a Holder of a Note pursuant to Section 508 hereof, or a suit by Holders of more than 10%
in principal amount of the then outstanding Notes.

 (a) 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 or willful misconduct 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; but in the case of any such certificates or opinions specifically required by any provision hereof to be provided to it, the Trustee shall be under a duty to examine the same to determine whether or not they conform
to the requirements of this Indenture, but not to verify the contents thereof. 
 (b) Subject to the protections of Article Six and Article
Fifteen hereof (including, but not limited to, the provision of indemnity or security as set forth in Section 603(5)), if an Event of Default has occurred and is continuing of which written notice of such Event of Default or failure to make
such payment shall have been given to the Trustee and the Collateral Agent, as applicable, by the Company, any other obligor of the Notes or by any Holder, the Trustee or the Collateral Agent, as applicable, shall exercise such of the rights and
powers vested in it by this Indenture, and the Trustee shall 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. 

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that: 
 (1) this paragraph (c) shall not be construed to limit
the effect of paragraph (a) of this Section; 
 (2) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

Documents unless the Trustee has been offered security or indemnity reasonably satisfactory to it against any loss, liability or exposure; and 

(5) no provision of this Indenture or the Security Documents shall be deemed to require the Trustee to expend or risk its own
funds or otherwise incur any liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. 

  
 -53-

Default in the payment of the principal of (or premium, if any, on) or interest on any Note, the Trustee shall be protected in withholding such notice if it determines that the withholding of such notice is in the interest of the Holders. In

Officers’ Certificate and/or an Opinion of Counsel and shall not be liable for any action it takes or omits to take in good faith reliance on such Officers’ Certificate and/or Opinion of Counsel;

 -54-

negligence; 
 (9) The rights, privileges, protections, immunities and benefits given to the Trustee pursuant to this
Indenture and the Security Documents, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including as Collateral Agent), and each agent, custodian and other Person
employed to act hereunder; and 
 (10) 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. 

SECTION 604. Trustee Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the Notes, except for the
Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this
Indenture, the Security Documents or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture and the Security Documents, authenticate the Notes and perform its obligations hereunder and under
the Security Documents. The Trustee shall not be accountable for the use or application by the Company of Notes or the proceeds thereof. 

SECTION 605. May Hold Notes. The Trustee, the Collateral Agent, any Paying Agent, any Note Registrar or any other agent of the Company
or of the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not the Trustee, the

resign.

out-of-pocket expenses, disbursements and advances and to indemnify and hold harmless the Trustee and the Collateral Agent shall constitute additional indebtedness

and the Collateral Agent shall have a claim prior to the Notes upon all property and funds held or collected by the Trustee and/or the Collateral Agent as such, except funds held in trust for the payment of principal of (and premium, if any) or
interest on particular Notes. 
 When the Trustee or the Collateral Agent incurs expenses or renders services in connection with an Event of
Default specified in Section 501(6), the expenses (including the reasonable charges and expenses of its counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable Bankruptcy

delivered to the resigning Trustee or resigning Collateral Agent, as applicable, and a copy to the successor Trustee or successor Collateral Agent, as applicable. If the instrument of acceptance by a successor Trustee or successor Collateral Agent,

Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA
Section 310(b)(1) are met. 
 (e) If the Trustee or the Collateral Agent shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of Trustee or Collateral Agent for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or successor Collateral Agent, as applicable. If, within one year after such resignation,

by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee or successor Collateral Agent, as applicable. 
 (f) The Company shall
give notice of each resignation and each removal of the Trustee or the Collateral Agent and each appointment of a successor Trustee or successor Collateral Agent to the Holders in the manner provided for in Section 107. Each notice shall
include the name of the successor Trustee or successor Collateral Agent, as applicable, and the address of its Corporate Trust Office. 

SECTION 610. Acceptance of Appointment by Successor. 

(a) Every successor Trustee and successor Collateral Agent appointed hereunder shall execute, acknowledge and deliver to the Company and to the
retiring Trustee or retiring Collateral Agent, as applicable, an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee or retiring Collateral Agent, as applicable, shall become effective and such
successor Trustee or successor Collateral Agent, as applicable, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee or retiring Collateral Agent, as applicable; but,

such successor Trustee or successor Collateral Agent, as applicable, all the rights, powers and trusts of the retiring Trustee or retiring Collateral Agent, as applicable, and shall duly assign, transfer and deliver to such successor Trustee or
successor Collateral Agent, as applicable, all property and money held by such retiring Trustee or retiring Collateral Agent, as applicable, hereunder and under the Security Documents. Upon request of any such successor Trustee or successor
Collateral Agent, as applicable, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee or successor Collateral Agent, as applicable, all such rights, powers and trusts.

eligible under this Article Six. 
 SECTION 611. Merger, Conversion, Consolidation or Succession to Business. Any corporation into
which the Trustee or the Collateral Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee or the Collateral Agent, as applicable, shall
be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee or the Collateral Agent, as applicable, shall be the successor of the Trustee or the Collateral Agent, as applicable, hereunder and
under the Security Documents; provided that such corporation shall be otherwise qualified 

  
 -57- 








 
and eligible under this Article Six, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee
had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee.
In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee; provided, however, that the right to adopt the certificate of authentication
of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

SECTION 612. Appointment of Authenticating Agent. At any time when any of the Notes remain Outstanding, the Trustee may appoint an
authenticating agent or agents with respect to the Notes which shall be authorized to act on behalf of the Trustee to authenticate Notes (an “Authenticating Agent”) and the Trustee shall give written notice of such appointment to
all Holders of Notes with respect to which such Authenticating Agent shall serve, in the manner provided for in Section 107. Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Company.
Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the
Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or state authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this
Section 612, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be

Whenever the Company shall have one or more Paying Agents for the Notes, it shall, on or before each due date of the principal of (or premium,
if any) or interest on any Notes, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of such action or any failure so to act. 

The Company shall cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section 1003, that such Paying Agent shall:

provided;

payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as Trustee thereof, shall thereupon cease.

the respective organizational documents (as the same may be amended from time to time) of the Company or any such Guarantor; provided, however, that the Company shall not be required to preserve any such corporate, limited liability

however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment or charge whose amount, applicability or validity is being contested in good faith by appropriate proceedings or

 -68- 








 
when not otherwise filing such reports with the SEC, posted such reports on IntraLinks or any comparable password protected online data system requiring user identification and a confidentiality
acknowledgment; provided that in all cases the Company shall make such information available to securities analysts and prospective investors upon request. For purposes of this Section 1009, the term “Company Website” means the
collection of web pages that may be accessed on the World Wide Web using the URL address http://www.aleris.com or such other address as the Company may from time to time designate in writing to the Trustee. In addition, the Company has agreed that,
for so long as any Notes remain Outstanding, it shall 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.
Notwithstanding the foregoing, the Company will not be required to furnish any information required by Item 3-10 or 3-16 of Regulation
S-X; provided that when neither the Company nor Parent are filing reports with the SEC, the Company shall provide guarantor / non-guarantor financial data

shall not be subject to the TIA. 
 (c) In addition, at the option of the Company, if the Company elects to no longer file reports with the
SEC, all such reports (i) shall not be required to comply with Section 302, Section 404 or Section 906 of the Sarbanes-Oxley Act of 2002, or related Items 307 or 308 of Regulation S-K

(d) In any event, the reports, information and other documents required to be furnished to the Holders pursuant to this Section 1009 may,
at the option of the Company, be furnished by and be those of Parent rather than the Company; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information
relating to Parent, on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a standalone basis, on the other hand. If Parent ceases to be a Guarantor of the Notes and, if at any subsequent time any direct or
indirect parent company of the Company becomes a guarantor of the Notes (there being no obligation of such parent to do so), the reports, information and other documents required to be furnished to the Holders pursuant to this Section 1009 may,
at the option of the Company, be furnished by and be those of such parent rather than the Company; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information
relating to such parent, on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a standalone basis, on the other hand. 

(e) Notwithstanding anything herein to the contrary, (i) the Company shall not be deemed to have failed to comply with any of its
obligations under this Section 1009 for the purposes of Section 501(3) until 120 days after the date any report hereunder is due and (ii) any failure to comply with this Section 1009 shall be automatically cured when the Company
or any direct or indirect parent of the Company, as the case may be, furnishes all required reports to the Holders or files all required reports with the SEC.

of such dividend or distribution in accordance with its Equity Interests in such class or series of securities;

(A) the principal amount of such new Indebtedness or liquidation preference of such new Disqualified Stock does not exceed the
principal amount (or accreted value, if applicable) of the Subordinated Indebtedness or the liquidation preference of the Disqualified Stock being so defeased, redeemed, repurchased, acquired or retired for value, plus the amount of any reasonable

Subsidiaries shall be Restricted Subsidiaries, other than Aleris Asia Pacific Limited, Aleris Aluminum Zhenjiang Co. Ltd. and Aleris (Shanghai) Trading Co. Ltd. and any of their direct and indirect Subsidiaries, which shall be Unrestricted
Subsidiaries (such entities, each an “Issue Date Unrestricted Subsidiary” and together, the “Issue Date Unrestricted Subsidiaries”). The Company shall not permit any Unrestricted Subsidiary to become a Restricted
Subsidiary except pursuant to the penultimate paragraph of the definition of “Unrestricted Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Company and the
Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation
shall be permitted only if a Restricted Payment in such amount would be permitted at such time, whether pursuant to Section 1010(a) or under clause (11) or (14) of Section 1010(b) or pursuant to the definition of “Permitted
Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Unrestricted Subsidiaries shall not be subject to any of the restrictive covenants set forth in this Indenture.

(A) making a Restricted Payment using clause (b)(11) of this Section 1010 or (B) (i) making a Restricted Payment in accordance with Section 1010(a), (ii) using clauses (b)(1) or (b)(7) of this Section 1010 or
(iii) using clause (p) of the definition of 

  
 -74- 








 
“Permitted Investments,” in each case in this clause (B), unless immediately after making any such Restricted Payment, the Consolidated Total Debt Ratio of the Company would not exceed
5.00 to 1.00, calculated as of the end of the most recently completed four consecutive fiscal quarters for which internal financial statements are available on a pro forma basis after making any such Restricted Payment and giving effect to the
incurrence of any Indebtedness to finance such payment (incorporating such pro forma adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of “Fixed Charge Coverage Ratio” with
such calculations made in good faith by a responsible financial or accounting officer of the Company).

are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.00 to 1.00, determined on a pro forma basis (including a pro forma
application of the net proceeds therefrom), as if the additional Indebtedness had been incurred, or the Disqualified Stock or Preferred Stock had been issued, as the case may be, and the application of the proceeds therefrom had occurred at the
beginning of such four-quarter period; provided, further. that the amount of Indebtedness (including Acquired Indebtedness), Disqualified Stock and Preferred Stock that may be incurred or issued, as applicable, pursuant to the
foregoing by Restricted Subsidiaries that are not Subsidiary Guarantors shall not exceed the greater of (x) $125.0 million and (y) 4.5% of Consolidated Total Assets at any one time outstanding.

categories of Permitted Debt described in clauses (1) through (22) of Section 1011(b) or is entitled to be incurred pursuant to Section 1011(a), the Company, in its sole discretion, shall classify or reclassify, or later divide,
classify or reclassify (based on circumstances existing at the time of such reclassification), such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) and shall only be required to include the amount and type of
such Indebtedness, Disqualified Stock or Preferred Stock in one or more of the above clauses; provided that (i) all Indebtedness outstanding under the ABL Facility on the Issue Date shall be deemed to have been incurred on such date in
reliance on the exception in clause (1)(x) of Section 1011(b) and may not be reclassified and (ii) all Indebtedness under the Term Loan Facility outstanding on the Issue Date will be deemed to have been incurred on such date in reliance on
the exception in clause (1)(y)(i) of Section 1011(b) and may not be reclassified; 
 (2) at the time of incurrence, the
Company shall be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 1011(a) and (b) without giving pro forma effect to the Indebtedness incurred pursuant to
Section 1011(b) when calculating the amount of Indebtedness that may be incurred pursuant to Section 1011(a); 

(3) with respect to Indebtedness incurred under a Credit Facility, reborrowings of amounts previously repaid pursuant to
“cash sweep” provisions or any similar provisions under such Credit Facility that provide that Indebtedness is deemed to be repaid daily (or otherwise periodically) shall only be deemed for purposes of Section 1011 to have been
incurred on the date such Indebtedness was first incurred and not on the date of any subsequent reborrowing thereof; and 

(4) any Credit Facility incurred under clause (1) of Section 1011(b) may be refinanced at any time if such
refinancing does not exceed the greater of (i) the aggregate principal amount of Indebtedness permitted to be incurred pursuant to such clause (1) of Section 1011(b) and (ii) the aggregate principal amount of the Credit Facility
being refinanced (together with any premiums or fees associated with such refinancing) and (A) in the case of a refinancing of Indebtedness outstanding under the ABL Facility on the Issue Date, such refinancing shall be treated for all purposes

(e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S.

or incurred (as determined by the Company), in the case of revolving credit debt; provided that if such Indebtedness is incurred to extend, replace, refund, refinance, renew or defease other Indebtedness denominated in a foreign currency, and
such extension, replacement, refunding, refinancing, renewal or defeasance would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such extension,
replacement, refunding, refinancing, renewal or defeasance, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of
such Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased. 

  
 -80- 








 (f) The principal amount of any Indebtedness incurred to extend, replace, refund, refinance,
renew or defease other Indebtedness, if incurred in a different currency from the Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased, shall be calculated based on the currency exchange rate applicable to the currencies
in which such respective Indebtedness is denominated that is in effect on the date of such extension, replacement, refunding, refinancing, renewal or defeasance.

Guarantors to, directly or indirectly, create, incur, assume or permit to exist any Lien that secures obligations under any Indebtedness on any asset or property of the Company or any Subsidiary Guarantor that does not constitute Collateral now
owned or hereafter acquired, or any income or profits therefrom, or assign or convey any right to receive income therefrom, unless: 
 (a)
such Lien is a Permitted Lien; or 
 (b) (1) in the case of any Lien securing Subordinated Indebtedness, the Notes or the applicable
Notes Guarantee of a Subsidiary Guarantor, as the case may be, are secured by a Lien on such property or assets that is senior in priority to such Lien and 

(2) in all other cases, the Notes or the applicable Notes Guarantee of a Subsidiary Guarantor, as the case may be, are secured
equally and ratably with (or prior to) the obligations secured by such Lien; 
 provided that any Lien which is granted to secure the Notes or a
Notes Guarantee under this sentence shall be discharged at the same time as the discharge of the Lien (other than through the exercise of remedies with respect thereto) that gave rise to the obligation to so secure the Notes or a Notes Guarantee.

 SECTION 1013. Limitations on Transactions with Affiliates.

involving aggregate payments or consideration in excess of $30.0 million, a Board Resolution adopted by the majority of the members of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officers’

 (d) Any Net Proceeds from any Asset Sale that are not invested or applied in accordance with the
preceding clauses (b) and (c) within 365 days or 35 days, as applicable, from the date of the receipt of such Net Proceeds shall be deemed to constitute “Excess Proceeds”; provided that if during such 365-day period the Company or a Restricted Subsidiary enters into a definitive binding agreement committing it to apply such Net Proceeds in excess of the Minimum Cash Consideration to the making of investments set

price in cash in an amount equal to 100% of the principal amount thereof (or, in the event such Other Second-Priority Obligations were issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid
interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Company shall commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date

Proceeds from an Asset Sale by making an Asset Sale Offer with respect to such Net Proceeds prior to the expiration of the relevant 365 day-period (or such longer period provided above) or 35 day period, as
applicable, or with respect to Excess Proceeds of $35.0 million or less. To the extent that the aggregate amount of Notes and such Other Second-Priority Obligations tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company may use any remaining Excess Proceeds for general corporate purposes (including for the avoidance of doubt pursuant to Section 1010, if available), subject to the other covenants contained in this Indenture. If the aggregate principal
amount of Notes and/or the Other Second-Priority Obligations surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Company shall select or cause to be selected the Notes and such Other Second-Priority Obligations to be
purchased on a pro rata basis based on, at the election of the Company, the accreted value or principal amount of the Notes or such Other Second-Priority Obligations tendered. Upon completion of any such Asset Sale Offer, the amount of Excess
Proceeds related to such Asset Sale Offer shall be reset at zero, and in the case of an Asset Sale Offer being effected in advance of being required to do so by this Indenture, the amount of Net Proceeds the Company is offering to apply in such
Asset Sale Offer shall be excluded in subsequent calculations of Excess Proceeds.

Collateral Account pending final application of any Net Proceeds of Non-ABL Priority Collateral pursuant to Section 1018(b) and in a manner that is otherwise permitted by this Indenture. Pending the final
application of any Net Proceeds pursuant to Section 1018(c), the Company or the applicable Restricted Subsidiary may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest
such Net Proceeds in any manner not prohibited by this Indenture. 
 (f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to an Asset Sale Offer.
To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations described in this Indenture by virtue thereof. 
 (g) If the Company is repurchasing less than all of the Notes at any time, the
Company shall select the Notes to be repurchased (a) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which such Notes are listed or (b) if
such Notes are not so listed, on a pro rata basis to the extent practicable; provided that no Notes of $2,000 or less shall be repurchased in part.

revolving credit facilities or other similar Indebtedness, to correspondingly permanently reduce commitments with respect thereto (other than Obligations owed to the Company or a Restricted Subsidiary); provided that if the Company or any
Subsidiary Guarantor shall so reduce Obligations under any Other Second-Priority Obligations, the Company or such Subsidiary Guarantor will either (x) equally and ratably, reduce Obligations under the Notes by, at its option, (A) redeeming
Notes as provided under Section 1011 or (B) purchasing Notes through open market purchases (to the extent such purchases are at a price equal to or higher than 100% of the principal amount thereof) in a manner that complies with this
Indenture and applicable securities law or (y) make an offer (in accordance with the procedures for a Loss Proceeds Offer set forth in Section 1020(c)) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the
amount of accrued and unpaid interest, if any, on the principal amount of Notes to be repurchased; or 

  
 -92- 








 (3) to make an investment in (A) any one or more businesses; provided
that such investment in any business is in the form of the acquisition of Capital Stock and results in the Company or any Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary;
provided, further. that such Capital Stock constitutes Collateral, (B) properties that constitute Collateral, (C) capital expenditures on or related to assets that constitute Collateral and (D) acquisitions of other assets that
constitute Collateral, that in each of subclause (A), (B), (C) and (D) of this clause (2), are used or useful in a Similar Business or replace the businesses, properties and assets that are the subject of such Event of Loss; or 

(4) any combination of the foregoing. 

(b) Any Net Loss Proceeds from any Event of Loss that are not invested or applied in accordance with the foregoing clause (a) within 365
days from the date of the receipt of such Net Loss Proceeds will be deemed to constitute “Excess Loss Proceeds”; provided that if during such 365-day period the Company or a Restricted
Subsidiary enters into a definitive binding agreement committing it to apply such Net Loss Proceeds to the making of investments set forth in Section 1020(a)(3) after such 365th day, such 365-day period
will be extended with respect to the amount of Net Loss Proceeds so committed until such Net Loss Proceeds are required to be applied in accordance with such agreement (but such extension will in no event be for a period longer than 180 days) (or,
if earlier, the date of termination of such agreement). 
 (c) When the aggregate amount of Excess Loss Proceeds exceeds $35.0 million,
the Company shall make an offer to all Holders and, if required by the terms of any Other Second-Priority Obligations, to the holders of such Other Second-Priority Obligations (other than with respect to Hedging Obligations) (a “Loss
Proceeds Offer”) to purchase the maximum aggregate principal amount of Notes and such Other Second-Priority Obligations that is in an amount equal to at least $2,000 that may be purchased out of the Excess Loss Proceeds at an offer price in
cash in an amount equal to 100% of the principal amount thereof (or, in the event such Other Second-Priority Obligations were issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest, if
any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Company shall commence a Loss Proceeds Offer with respect to Excess Loss Proceeds within ten Business Days after the date that
Excess Loss Proceeds exceed $35.0 million by mailing or electronically sending the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Company may satisfy the foregoing obligations with respect to any Excess
Loss Proceeds from an Event of Loss by making a Loss Proceeds Offer with respect to such Excess Loss Proceeds prior to the expiration of the relevant 365 day-period (or such longer period provided
above) or with respect to Excess Loss Proceeds of $35.0 million or less. 
 (d) To the extent that the aggregate amount of Notes and
such Other Second-Priority Obligations tendered pursuant to a Loss Proceeds Offer is less than the Excess Loss Proceeds, the Company may use any remaining Excess Loss Proceeds for general corporate purposes (including for the avoidance of doubt,
pursuant to Section 1010 of this Indenture, if available), subject to the other covenants contained in this Indenture. If the aggregate principal amount of Notes and/or the Other Second-Priority Obligations surrendered by such holders thereof
exceeds the amount of Excess Loss Proceeds, the Trustee shall select, or cause to be selected, the Notes and such Other Second-Priority Obligations to be purchased on a pro rata basis based on, at the election of the Company, the accreted value or
principal amount of the Notes or such Other Second-Priority Obligations tendered. Upon completion of any such Loss Proceeds Offer, the amount of Excess Loss Proceeds related to such Loss Proceeds Offer shall be reset at zero, and in the case of a
Loss Proceeds Offer being effected in advance of being required to do so by this Indenture, the amount of Net Loss Proceeds the Company is offering to apply in such Loss Proceeds Offer shall be excluded in subsequent calculations of Excess Loss
Proceeds. 
 (e) Pending the final application of any Excess Loss Proceeds pursuant to this Section 1020 and in a manner that is
otherwise permitted by this Indenture, when the amount of any Excess Loss Proceeds exceeds $10 million, the Company or the applicable Subsidiary Guarantor shall deposit such Excess Loss Proceeds into the Collateral Account; provided that
upon the occurrence and during the continuance of a Default, all such Excess Loss Proceeds shall be deposited into and remain in the Collateral Account pending the final application of any Excess Loss Proceeds pursuant to this Section 1020 and
in a manner that is otherwise permitted by this Indenture. 

  
 -93- 








 (f) The Company shall comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to a Loss
Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have
breached its obligations described in this Indenture by virtue thereof. 
 (g) If the Company is repurchasing less than all of the Notes at
any time, the Company shall select the Notes to be repurchased (a) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which such Notes are listed or
(b) if such Notes are not so listed, on a pro rata basis to the extent practicable; provided that no Notes of $2,000 or less shall be repurchased in part. 

(h) Within 30 days after the Company becomes obligated to make a Loss Proceeds Offer, the Company shall send notice of that Loss Proceeds Offer
electronically or by first class mail, with a copy to the Trustee, to each Holder to the address of that Holder appearing in the security register of Holders, or otherwise in accordance with the procedures of the Depository with a copy to the
Trustee, with the following information: 
 (1) a Loss Proceeds Offer is being made pursuant to this Section 1020, the
total amount of the Loss Proceeds Offer, and that all Notes properly tendered pursuant to the Loss Proceeds Offer shall be accepted for payment, subject to prorating if the aggregate principal amount of Notes tendered is greater than the amount of
the Loss Proceeds Offer, as contemplated by Sections 1020(d) and (g); 
 (2) the purchase price and the purchase date, which
shall be no earlier than 30 days nor later than 60 days from the date such notice is delivered (the “Event of Loss Payment Date”); 

(3) any Note not properly tendered shall remain outstanding and continue to accrue interest; 

(4) unless the Company defaults in the payment of the Loss Proceeds Offer, all Notes accepted for payment pursuant to the Loss
Proceeds Offer shall cease to accrue interest on the Event of Loss Payment Date; 
 (5) Holders electing to have any Notes
purchased pursuant to a Loss Proceeds Offer shall be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed, to the paying agent specified in the notice at the
address specified in the notice prior to the close of business on the third Business Day preceding the Event of Loss Payment Date; 

(6) Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase such
Notes; provided that the paying agent receives, not later than the close of business on the last day of the offer period, an electronic transmission, facsimile transmission, or letter setting forth the name of the Holder, the principal amount
of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; and 

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

(i) While the Notes are in global form and the Company makes a Loss Proceeds Offer, a Holder may exercise its option to elect for the purchase
of the Notes through the facilities of DTC, subject to its rules and regulations. 
 (j) On the Event of Loss Payment Date, the Company
shall, to the extent permitted by law, 

  
 -94- 








 (1) accept for payment all Notes or portions thereof properly tendered pursuant
to the Loss Proceeds Offer, 
 (2) deposit with the Paying Agent an amount equal to the aggregate payment of the Loss
Proceeds Offer, and 
 (3) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together
with an Officers’ Certificate stating that such Notes or portions thereof have been tendered to and purchased by the Company. 
 (k) The
Paying Agent shall promptly mail to each Holder the payment for such Notes in respect of the Loss Proceeds Offer, and the Trustee shall promptly authenticate and mail to each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company shall publicly announce the results of the Loss Proceeds Offer on or as
soon as practicable after the Event of Loss Payment Date. Subject to any laws relating to abandoned property, the Paying Agent, if not the Company, shall return to the Company any cash that remains unclaimed, together with interest, if any, thereon,
held by the Paying Agent for the payment of the amount required pursuant to the Loss Proceeds Offer. The Trustee shall have no requirement to invest any such cash unless directed by the Company in writing and such investment shall be mutually
acceptable to the Trustee and the Company. 
 SECTION 1021. Covenant Termination. 

If on any date following the date of this Indenture: 

(1) the Notes are rated Baa3 or better by Moody’s and BBB- or better by S&P
(or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” registered under
Section 15E of the Exchange Act selected by the Company as a replacement agency); and 
 (2) no Default or Event of
Default shall have occurred and be continuing, 
 then, beginning on that day, the Company and its Restricted Subsidiaries will no longer be
subject to the following provisions of this Indenture: 
 (1) Section 1018; 

(2) Section 1010; 

(3) Section 1011; 

(4) Section 1016; 

(5) Section 801(a)(4); 

(6) Section 1013; 

(7) Section 1014; and 

(8) Section 1015. 

SECTION 1022. After-Acquired Property. 

  
 -95- 








 Within the time periods (and subject to the thresholds) set forth in this Indenture or in the
Security Documents following the acquisition by the Company or any Guarantor of any After-Acquired Property (but subject to the limitations, if applicable, described under Article Fifteen and in the Security Documents), the Company or such Guarantor
shall comply with the requirements of Section 3.6 of the Security Agreement and execute and deliver such mortgages, deeds of trust, security instruments, title insurance policies, financing statements, certificates, opinions of counsel and all
ancillary documents thereto, as shall be reasonably necessary to vest in the Collateral Agent a perfected security interest (subject to Permitted Liens) in such After-Acquired Property and to have such After-Acquired Property added to the
Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect; provided that in the case of Collateral
that consists of real property and improvements, the Company or the applicable Guarantor shall only be required to use commercially reasonable efforts to effectuate the foregoing within one hundred and fifty (150) days or as soon as practicable
thereafter upon the acquisition of such After-Acquired Property and shall only be required to take ministerial actions to cure defects in title to the extent necessary to obtain a valid Mortgage and title insurance, but would not be required to pay
more than de minimis fees and expenses to cure any title defects. Notwithstanding anything in this Indenture or any Security Document to the contrary, no default under this Indenture or any Security Document will be triggered if the Company
or any Guarantor fails to deliver a Mortgage or title insurance in spite of its use of commercially reasonable efforts to do so. The Company and each Guarantor agrees that, in the event the Company or such Guarantor takes any action to grant or
perfect a Lien in favor of the First-Priority Collateral Agent (or other collateral agent with respect to any First-Priority Obligations) or the ABL Facility Collateral Agent in any assets, the Company or such Guarantor shall also take such action
to grant or perfect a Lien (subject to the Intercreditor Agreements) in favor of the Collateral Agent to secure the Indenture Obligations without request of the Collateral Agent; provided that such action shall not impose additional duties,
liabilities or obligations on the part of the Collateral Agent without its consent and shall provide for such indemnifications and protections as the Collateral Agent may reasonably request. No actions in any jurisdiction outside the United States
will be required in order to create any security interests in assets located or titled outside of the United States, or to perfect any security interests in such assets, including any intellectual property registered in any jurisdiction outside the
United States. Notwithstanding anything to the contrary herein, in no event shall the Collateral Agent be required to register in any foreign jurisdiction or pursuant to any foreign local law, and the Pledgors shall not be required to perfect the
security interest in any Collateral that would require the Collateral Agent to make such registration.

REDEMPTION OF NOTES 

SECTION 1101. Right of Redemption. 

(a) [Reserved]. 
 (b) At any time
prior to July 15, 2020, the Company may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium
as of, and accrued and unpaid interest, if any, to the Redemption Date, subject to the rights of Holders on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date. 

(c) From and after July 15, 2020, the Company may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’
prior notice at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, thereon to the applicable Redemption Date, subject to the right of Holders of record on the relevant
Regular Record Date to receive interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on July 15 of each of the years indicated below: 

 

					
	Year	  	Percentage	 
	 2020
	  	 	104.000	% 
	 2021
	  	 	102.000	% 
	 2022 and thereafter
	  	 	100.000	% 


  
 -96- 








 (d) Prior to July 15, 2020, the Company may, at its option, redeem up to 40% of the sum of
the original aggregate principal amount of Notes (and the original principal amount of any Additional Notes) issued under this Indenture at a redemption price equal to 110.750% of the aggregate principal amount thereof, plus accrued and unpaid
interest, if any, thereon to the applicable Redemption Date, subject to the right of Holders of record on the Regular Record Date to receive interest due on the relevant Interest Payment Date, with funds in an amount equal to all or a portion of the
net cash proceeds of one or more Equity Offerings of the Company or any direct or indirect parent of the Company to the extent such net cash proceeds are contributed to the Company; provided that: 

(1) at least 60% of the sum of the aggregate principal amount of the Notes originally issued under this Indenture and the
aggregate principal amount of any Additional Notes issued under this Indenture after the Issue Date remain Outstanding immediately after the occurrence of each such redemption (unless all Notes Outstanding on the Redemption Date are redeemed); and

 (2) that each such redemption occurs within 180 days of the date of closing of each such Equity Offering. 

(e) If a Change of Control occurs (x) at any time on or prior to July 15, 2019, the Company (or a third party on behalf of the
Company) may, at its option, redeem all, but not less than all, of the Notes, at a redemption price equal to 102.000% of the principal amount of the Notes and (y) at any time after July 15, 2019 but on or prior to July 15, 2020, the
Company (or a third party on behalf of the Company) may, at its option, redeem all, but not less than all, of the Notes, at a redemption price equal to 103.000% of the principal amount of the Notes, in each case, plus accrued and unpaid interest, if
any, thereon to the applicable Redemption Date, subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date (a “Change of Control Redemption”). If the
Company (or such third party) elects to exercise this redemption right, it must do so by sending a redemption notice to each Holder with a copy to the Trustee within 30 days following the Change of Control (or, at the Company’s option, prior to
such Change of Control but after the transaction giving rise to such Change of Control is publicly announced). Any such redemption may be conditioned upon the Change of Control occurring if the notice is sent prior to the Change of Control. If the
Company (or such third party) exercises the Change of Control Redemption right, the Company may elect not to make the Change of Control Offer pursuant to Section 1017 unless it defaults in payments due upon redemption. 

(f) Upon consummation by the Company or any Restricted Subsidiary of one or more Asset Sales generating Net Proceeds in excess of
$35.0 million in the aggregate (x) at any time on or prior to July 15, 2019, the Company may, at its option, redeem all or a portion of the Notes in an aggregate principal amount not to exceed such Net Proceeds, at a redemption price
equal to 102.000% of the principal amount of the Notes and (y) at any time after July 15, 2019 but on or prior to July 15, 2020, the Company may, at its option, redeem all or a portion of the Notes in an aggregate principal amount not
to exceed such Net Proceeds, at a redemption price equal to 103.000% of the principal amount of the Notes, in each case, plus accrued and unpaid interest, if any, thereon to the applicable Redemption Date, subject to the right of Holders of record
on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date (an “Asset Sale Redemption”). If the Company elects to exercise this redemption right, it must do so by sending a notice of an Asset
Sale Redemption at least 30 days prior to such Redemption Date to each Holder with a copy to the Trustee. Any such redemption may be conditioned upon the consummation of an Asset Sale if the notice is sent prior to consummation of such Asset Sale.
For the avoidance of doubt, any cash actually applied to redeem Notes pursuant to an Asset Sale Redemption shall be excluded from the calculation of Excess Proceeds and therefore the requirement to make an Asset Sale Offer. 

SECTION 1102. Mandatory Redemption. The Company shall not be required to make any mandatory redemption or sinking fund payments with
respect to the Notes. 
 SECTION 1103. Applicability of Article. Redemption of Notes at the election of the Company or otherwise, as
permitted or required by any provision of this Indenture or the Notes, shall be made in accordance with such provision and this Article Eleven.

(iii) the principal amount of the Notes to be redeemed and (iv) the Redemption Price. Any notice to the Trustee delivered pursuant to this Section 1104 may be revoked by the Company prior to the delivery of any notice of redemption
sent to Holders. 
 SECTION 1105. Selection by Trustee of Notes to Be Redeemed. 

(a) If the Company is redeeming less than all of the Notes at any time, the Trustee shall select the Notes to be redeemed (a) if the Notes
are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which such Notes are listed or (b) if such Notes are not so listed, on a pro rata basis to the extent
practicable; provided that no Notes of $2,000 or less shall be redeemed in part. 
 (b) If any Note is to be redeemed in part only,
any notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. 
 (c) A new Note
in principal amount equal to the unredeemed portion of any Note redeemed in part shall be issued in the name of the Holder thereof upon cancellation of the original Note. Subject to the second paragraph of Section 1106, Notes called for
redemption become due and payable on the date fixed for redemption. On and after the Redemption Date, unless the Company defaults in the redemption payment, interest shall cease to accrue on the Note or portions thereof called for redemption. 

SECTION 1106. Notice of Redemption. Notices of redemption shall be sent electronically or mailed by first-class mail, postage prepaid,
or otherwise provided in accordance with the procedures of the Depository, at least 30 days but not more than 60 days before the Redemption Date to each Holder at such Holder’s registered address or otherwise in accordance with the procedures
of the Depository, except that notices of redemption may be delivered more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. For Notes that
are represented by global certificates held on behalf of the Depository, notices may be given by delivery of the relevant notices to the Depository for communication to entitled account holders in substitution of the aforementioned delivery. 

In connection with any redemption of Notes (including with the net cash proceeds of an Equity Offering), any such redemption may, at the
Company’s discretion, be subject to satisfaction or waiver of one or more conditions precedent, including any related Equity Offering. 

All notices of redemption shall state: 

(1) the Redemption Date, 

(2) the Redemption Price and the amount of accrued interest to the Redemption Date payable as provided in Section 1108, if
any, 
 (3) if less than all Outstanding Notes are to be redeemed, the identification (and, in the case of a partial
redemption, the principal amounts) of the particular Notes to be redeemed, 
 (4) in case any Note is to be redeemed in part
only, the notice which relates to such Note shall state that on and after the Redemption Date, upon surrender of such Note, the Holder shall receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof
remaining unredeemed, 

  
 -98- 








 (5) that on the Redemption Date the Redemption Price (and accrued interest, if
any, to the Redemption Date payable as provided in Section 1108) shall become due and payable upon each such Note, or the portion thereof, to be redeemed, and that interest thereon shall cease to accrue on and after said date, subject to any
condition precedent in that notice, 
 (6) the place or places where such Notes are to be surrendered for payment of the
Redemption Price and accrued interest, if any, 
 (7) the name and address of the Paying Agent, 

(8) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price, 

(9) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to
accrue on and after the Redemption Date, 
 (10) the “CUSIP” number, ISIN or “Common Code” number and
that no representation is made as to the accuracy or correctness of the “CUSIP” number, ISIN or “Common Code” number, if any, listed in such notice or printed on the Notes, 

(11) the paragraph of the Notes or Section of this Indenture pursuant to which the Notes are to be redeemed, and 

(12) any conditions precedent to which the redemption or notice is subject to and that, in the Company’s discretion, the
Redemption Date may be delayed until such time as any or all such conditions shall be satisfied or waived, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied
or waived by the Redemption Date, or by the Redemption Date so delayed. 
 The Company may provide in any notice of redemption that payment
of the Redemption Price or performance of the Company’s obligations with respect to the redemption may be performed by a third party if such third party makes such payment and satisfies such obligations in compliance with the requirements set
forth in this Indenture. 
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at
its expense; provided that the Company shall have delivered to the Trustee, at least five Business Days before notice of redemption is required to be delivered or caused to be delivered to Holders pursuant to this Section 1106 (unless a
shorter notice shall be agreed to by the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 1104. 

SECTION 1107. Effect of Notice of Redemption. Once notice of redemption is delivered in accordance with Section 1106 hereof, Notes
called for redemption become irrevocably due and payable on the Redemption Date at the Redemption Price, subject to any condition precedent set forth in that notice. The notice, if delivered in a manner herein provided, shall be conclusively
presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity
of the proceedings for the redemption of any other Note. Subject to Section 1108 hereof, on and after the Redemption Date, interest shall cease to accrue on Notes or portions of Notes called for redemption. 

SECTION 1108. Deposit of Redemption Price. Prior to 1:00 p.m. (Eastern Time) on any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and accrued interest, if any, on, all
the Notes that are to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption
price of, and accrued and unpaid interest, if any, on, all Notes to be redeemed or purchased. In addition, all money, if any, earned on funds held by the Trustee or the Paying Agent shall be remitted to the Company. 

  
 -99- 








 SECTION 1109. Notes Payable on Redemption Date. 

(a) Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date and assuming the
satisfaction or waiver of any conditions precedent, become due and payable at the Redemption Price therein specified (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in
the payment of the Redemption Price and accrued interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price,
together with accrued interest, if any, to the Redemption Date and such Notes shall be canceled by the Trustee; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provisions of Section 306. 

(b) If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the Notes. 
 SECTION 1110. Notes Redeemed in Part. Any Note
which is to be redeemed only in part (pursuant to the provisions of this Article Eleven) shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to Section 1002 (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Note so surrendered; provided that no Note of $2,000 or less will be redeemed in part.

 NOTES GUARANTEES 

SECTION 1201. Notes Guarantees. Each Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees,
as primary obligor and not merely as surety, the Notes and obligations of the Company hereunder and thereunder and the obligations of the Company and each other Guarantor under the Security Documents, and guarantees to each Holder of a Note
authenticated and delivered by the Trustee, and to the Trustee for itself and on behalf of such Holder, that: (1) the principal of (and premium, if any) and interest on the Notes shall be paid in full when due, whether at Stated Maturity, by
acceleration or otherwise (including the amount that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Law), subject to any applicable grace period, together with interest on the overdue
principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be paid in full or performed, all in accordance with the terms hereof
and thereof; and (2) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at
Stated Maturity, by acceleration or otherwise, subject to any applicable grace period, and subject, however, in the case of clauses (1) and (2) above, to the limitation set forth in Section 1204 hereof. 

(a) Each Guarantor hereby agrees that (to the extent permitted by law) its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, any release of any other Guarantor, the
recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor (other than payment in full of the principal of, and
premium and interest, if any, on, the Notes). 

  
 -100- 








 (b) Each Guarantor hereby waives (to the extent permitted by law) the benefits of diligence,
presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or any other Person, protest, notice and all demands whatsoever and
covenants that the Notes Guarantee of such Guarantor shall not be discharged as to any Note except by complete performance of the obligations contained in such Note, this Indenture and such Notes Guarantee. Each Guarantor acknowledges that the Notes
Guarantee is a guarantee of payment, performance and compliance when due and not of collection. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal (or premium, if any) or interest on such Note, whether at
its Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of
the Guarantors to enforce such Guarantor’s Notes Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee
or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the Maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes,
such Guarantor shall pay to the Trustee for the account of the Holder, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

 (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company or any Guarantor, or any custodian,
trustee, liquidator or other similar official acting in relation to either the Company or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Notes Guarantee of each of the Guarantors, to the extent theretofore
discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (1) subject to this Article Twelve, the Maturity of
the obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of the Notes Guarantee of such Guarantor notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of
the obligations guaranteed hereby, and (2) in the event of any acceleration of such obligation as provided in Article Five hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for
the purpose of the Notes Guarantee of such Guarantor. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of
the Holders under the Notes Guarantees. 
 (d) Each Notes Guarantee shall remain in full force and effect and continue to be effective should
any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of
the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in
amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that
any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

 SECTION 1202. Severability. In case any provision of any Notes Guarantee shall be invalid, illegal or unenforceable, the validity,
legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby to the extent permitted by applicable law. 

SECTION 1203. Reserved. 

SECTION 1204. Limitation of Subsidiary Guarantors’ Liability. Each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder hereby confirms that it is the intention of all such parties that the Notes Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent
Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Notes Guarantee or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing
intention, the Trustee, the Holders and each such Subsidiary Guarantor hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Notes Guarantee shall be limited to the maximum amount as will, after giving effect to such
maximum amount and all other contingent and fixed liabilities of such Subsidiary Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any
other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article Twelve, result in the obligations of such Subsidiary Guarantor under its Notes Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under applicable law. 

  
 -101- 








 SECTION 1205. Contribution. Each Guarantor that makes a payment under its Notes Guarantee
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. 
 SECTION 1206. Subrogation. Each
Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 1201; provided, however, that, if a Default or Event of Default has occurred
and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Notes shall have been
paid in full. 
 SECTION 1207. Reinstatement. Each Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree) that
the Notes Guarantee provided for in Section 1201 shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligations or interest thereon is properly rescinded or must otherwise
be restored by a Holder to the Company upon the bankruptcy or insolvency of the Company or any Guarantor. 
 SECTION 1208. Release of a
Subsidiary Guarantor. The Notes Guarantee of a Subsidiary Guarantor, together with any pledge of the equity interests of such Subsidiary Guarantor or Lien on or security interest in any assets of such Subsidiary Guarantor, shall automatically
and unconditionally be released and discharged, and no further action by such Subsidiary Guarantor, the Company, the Trustee or the Collateral Agent is required for the release of such Subsidiary Guarantor’s Notes Guarantee, together with any
pledge of the equity interests of such Subsidiary Guarantor or Lien on or security interest in any assets of such Subsidiary Guarantor, upon: 

(1) (A) the sale, disposition or other transfer (including through merger or consolidation) of all of the Capital Stock (or any
sale, disposition or other transfer of Capital Stock following which such Subsidiary Guarantor is no longer a Restricted Subsidiary), or all or substantially all the assets, of such Subsidiary Guarantor (other than a sale, disposition or other
transfer to a Restricted Subsidiary that is not a Subsidiary Guarantor) if such sale, disposition or other transfer is made in compliance with Sections 802 and 1018(a) of this Indenture; 

(B) the designation by the Company of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with
Section 1010 of this Indenture and the definition of “Unrestricted Subsidiary”; 
 (C) with respect to any
entity that becomes a Subsidiary Guarantor after the Issue Date, the release or discharge of such Subsidiary Guarantor from its guarantee of Indebtedness under the ABL Facility and the Term Loan Facility (other than as a result of the payment of
such Indebtedness) or the guarantee that resulted in the obligation of such Subsidiary Guarantor to guarantee the Notes, in each case, if such Subsidiary Guarantor would not then otherwise be required to guarantee the Notes pursuant to
Section 1015 of this Indenture (treating any guarantees of such Subsidiary Guarantor that remain outstanding as incurred at least 45 days prior to such release or discharge); or 

(D) the exercise by the Company of its Legal Defeasance of the Notes under Section 1302 of this Indenture or its Covenant
Defeasance of the Notes under Section 1303 of this Indenture or if the Company’s obligations under this Indenture are discharged in accordance with Section 401 of this Indenture; and 

  
 -102- 








 (2) in the case of clause (1)(A) above, the release or discharge of such
Subsidiary Guarantor from its guarantee, if any, of and all pledges and security, if any, granted by such Subsidiary Guarantor in connection with, the ABL Facility and the Term Loan Facility.

arrangements contemplated by this Indenture and from its guarantee and waivers pursuant to its Notes Guarantees under this Article Twelve. 

ARTICLE THIRTEEN 
 LEGAL
DEFEASANCE AND COVENANT DEFEASANCE 
 SECTION 1301. Company’s Option to Effect Legal Defeasance or Covenant
Defeasance. The Company may, at its option, and at any time, elect to have either Section 1302 or Section 1303 be applied to all Outstanding Notes upon compliance with the conditions set forth below in this Article Thirteen. 

SECTION 1302. Legal Defeasance and Discharge. Upon the Company’s exercise under Section 1301 of the option applicable to this
Section 1302, each of the Company and the Guarantors shall be deemed to have been discharged from its respective obligations with respect to all Outstanding Notes and Notes Guarantees (including obligations under this Indenture and the Security
Documents) on the date the conditions set forth in Section 1304 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that each of the Company and the Guarantors shall be deemed to have
paid and discharged the entire indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1305 and the other Sections of this Indenture referred to in
clauses (1) and (2) below, and to have satisfied all its other obligations under such Notes, Notes Guarantees, this Indenture and the Security Documents insofar as such Notes and their related Notes Guarantees are concerned, the Collateral
shall be released and all then existing Events of Default shall be deemed cured (and the Trustee and the Collateral Agent, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder or under the Security Documents, as applicable: 
 (1) the rights
of Holders of Outstanding Notes to receive payments in respect of the principal of (and premium, if any, on) and interest on such Notes when such payments are due, solely out of the trust created pursuant to this Indenture (as described in Sections
1304 and 1305), 
 (2) the Company’s obligations with respect to such Notes under Sections 303, 304, 305, 1002 and 1003,

 (3) the rights, powers, trusts, duties and immunities of the Trustee and the Collateral Agent hereunder or under the
Security Documents, as applicable, and the obligations of each of the Company and the Guarantors in connection therewith and 

(4) this Article Thirteen. 

Subject to compliance with this Article Thirteen, the Company may exercise its option under this Section 1302 notwithstanding the prior
exercise of its option under Section 1303 with respect to the Notes. 
 SECTION 1303. Covenant Defeasance. Upon the
Company’s exercise under Section 1301 of the option applicable to this Section 1303, each of the Company and the Guarantors shall be released from its respective obligations under any covenant contained in Sections 801 and 802 and in
Sections 1005 through 1007 and 1009 through and including 1020 and any covenant contained in the Security Documents with respect to the Outstanding Notes on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Company or any Guarantor, as


  
 -103- 








 
applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under
Sections 501(3), 501(4), 501(5), 501(7) and 501(8) and, with respect to only any Significant Subsidiary and not the Company, Section 501(6), but, except as specified above, the remainder of this Indenture, such Notes and the Security Documents
shall be unaffected thereby. 
 SECTION 1304. Conditions to Legal Defeasance or Covenant Defeasance. The following shall be the
conditions to application of either Section 1302 or Section 1303 to the Outstanding Notes: 
 (1) the Company or
any Guarantor shall irrevocably have deposited with the Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Article Thirteen applicable to it) in trust for the benefit of
Holders of such Notes: (A) cash in U.S. dollars, (B) non-callable Government Securities or (C) a combination thereof, in such amounts as shall be sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay, and which shall be applied by the Trustee (or other qualifying trustee) to pay, the principal of, premium, if any, and
interest due on the Outstanding Notes on the Stated Maturity or Redemption Date, as the case may be; provided that the Trustee shall have been irrevocably instructed to apply such cash or the proceeds of such Government Securities to said
payments with respect to the Notes; before such a deposit, the Company may give to the Trustee, in accordance with Section 1104 hereof, a notice of its election to redeem all of the Outstanding Notes at a future date in accordance with Article
Eleven hereof, which notice shall be irrevocable; such irrevocable redemption notice, if given, shall be given effect in applying the foregoing; 

(2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, 
 (A) the Company has
received from, or there has been published by, the United States Internal Revenue Service a ruling, or 
 (B) since the
original issuance of the Notes, there has been a change in the applicable U.S. Federal income tax law, 
 in either case to the effect that,
and based thereon such Opinion of Counsel in the United States shall confirm that, subject to customary assumptions and exclusions, the beneficial owners of the Outstanding Notes shall not recognize income, gain or loss for U.S. Federal income tax
purposes as a result of such Legal Defeasance and shall be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the beneficial owners of the Outstanding Notes shall not recognize income, gain or loss for U.S. Federal income tax purposes as a result of
such Covenant Defeasance and shall be subject to such tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default (other than that resulting from borrowing funds to be applied to make such deposit and the granting of Liens in
connection therewith) shall have occurred and be continuing on the date of such deposit; 
 (5) such Legal Defeasance or
Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any Credit Facility, the 6% Senior Subordinated Debt Documents, the 6% Senior Subordinated Exchangeable Notes or any other material agreement or
instrument (other than this Indenture) to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 

  
 -104-

States of America (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for in this Indenture relating to the Legal Defeasance or the Covenant Defeasance, as the case
may be, have been complied with. 
 Notwithstanding the foregoing, the Opinion of Counsel required by clause (2) above with respect to
Legal Defeasance need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation (A) have become due and payable by reason of the making of a notice of redemption or otherwise, (B) will become due and payable
within one year or (C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 

SECTION 1305. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. All cash and Government
Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1305, the “Qualifying Trustee”) pursuant to Section 1304 in respect of the
Outstanding Notes shall be held in trust and applied by the Qualifying Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or a Subsidiary
acting as its own Paying Agent) as the Qualifying Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such money or Government Securities need
not be segregated from other funds except to the extent required by law. 
 The Company shall pay and indemnify the Qualifying Trustee
against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law
is for the account of the beneficial owners of the Outstanding Notes. 
 Anything in this Article Thirteen to the contrary notwithstanding,
the Qualifying Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Securities held by it as provided in Section 1304 which, in the opinion of a nationally recognized firm of independent
public accountants, expressed in a written certification thereof delivered to the Qualifying Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance,
as applicable, in accordance with this Article Thirteen. 
 SECTION 1306. Reinstatement. If the Trustee or any Paying Agent is unable
to apply any money or Government Securities in accordance with Section 1305 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and
each Guarantor’s obligations under this Indenture, the Outstanding Notes, the Notes Guarantees and the Security Documents shall be revived and reinstated as though no deposit had occurred pursuant to Section 1302 or 1303, as the case may
be, until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 1305; provided, however, that (a) if the Company makes any payment of principal of
(or premium, if any) or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the
Trustee or Paying Agent; and (b) unless otherwise required by any legal proceeding or any other order or judgment of any court or governmental authority, the Trustee or Paying Agent (if other than the Company) shall return all such money and
Government Securities to the Company promptly after receiving a written request therefor at any time, if such reinstatement of the Company’s obligations has occurred and continues to be in effect. 

  
 -105- 








 SECTION 1307. Repayment to Company. Subject to any laws relating to abandoned property,
any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if
any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

sold, transferred or otherwise disposed of by the Company or any Guarantor (other than to the Company or another Guarantor) in a transaction not prohibited by this Indenture at the time of such sale, transfer or disposition, (b) is owned or at
any time acquired by a Guarantor that has been released from its Notes Guarantee pursuant to Section 1208, concurrently with the release of such Notes Guarantee or (c) is or becomes an Excluded Asset pursuant to a transaction not
prohibited by this Indenture; or 
 (c) released in whole or in part as described in the Intercreditor Agreements; 

(d) to subordinate or release any Lien on any property to the holder of any Lien on such property that is permitted by clause (18) (in respect
of Indebtedness incurred under Section 1011(b)(18)) of the definition of “Permitted Liens” or, in the case of subordination only, clause (9) of the definition of “Permitted Liens,” in each case, to the extent and for so
long as the contract or other agreement in which such Lien is granted validly prohibits the creation of any other Lien (or, in the case of subordination, any senior Lien) on such property; and 

(e) in whole or in part, as described in Article Nine. 

SECTION 1505. Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or trustee,
lawfully appointed, the powers conferred in this Article Fifteen upon the Company or a Guarantor with respect to the release, subordination, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument
signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or a Guarantor or of any Officer or Officers thereof required by the provisions of this Article Fifteen; and if the Trustee or the Collateral
Agent shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee or the Collateral Agent, as the case may be. 

SECTION 1506. Post-Closing Collateral. Within 150 days after the Issue Date (or such later date as may be extended by the
First-Priority Collateral Agent pursuant to the terms of the Term Loan Facility) using commercially reasonable efforts, the Company shall deliver to the Initial Purchasers, the Trustee and the Collateral Agent each of the following documents, which
shall be substantially in the form of the comparable documents delivered by the Company to the First-Priority Collateral Agent pursuant to the terms of Term Loan Facility, and which shall be in customary form (as determined by the Company in its
sole reasonable discretion), and all ancillary documents thereto, which documents shall contain only such obligations, duties, benefits indemnities and protections on the part of the Collateral Agent which are reasonably acceptable to it: 

(i) Insurance. Policies or certificates of insurance covering the property and assets of the Company and the Guarantors,
which policies or certificates, including endorsements thereto, shall reflect the Collateral Agent for its benefit and the benefit of the Trustee and the holders of the Notes, as additional insured and loss payee and mortgagee, as applicable. 

  
 -109- 








 (ii) Mortgages. Fully executed counterparts of the Mortgages encumbering
the Mortgaged Property, it being understood that if a mortgage tax will be owed on the entire amount of the indebtedness, then the amount secured by said Mortgage shall be limited to the fair market value of the property at the time the Mortgage is
entered into if such limitation results in such mortgage tax being calculated upon such fair market value. 
 (iii) Title
Insurance. With respect to each Mortgage, a loan policy of title insurance (or commitment to issue such a policy having the effect of a loan policy of title insurance) insuring (or committing to insure) the lien of such Mortgage as a valid and
enforceable second priority mortgage or deed of trust lien on the fee estate of the Mortgaged Property described therein (each such policy, a “Mortgage Policy”) issued by such title insurance company in an amount equal to the fair
market value of the land and improvements on the Mortgaged Property (based on the most recently available tax assessments for such Mortgaged Property) and with customary endorsements so long as such endorsements are available in the applicable
jurisdiction and available at commercially reasonable rates, which Mortgage Policy provides that the Mortgage on such Mortgaged Property is a valid and enforceable mortgage lien on the Mortgaged Property, free and clear of all defects and
encumbrances other than Permitted Liens. All such Mortgage Policies may be subject to a survey exception. 
 (iv) Fixture
Filings. Proper fixture filings under the UCC on Form UCC-1 or in the applicable Mortgage for filing under the UCC in the appropriate jurisdiction in which the Mortgaged Properties are located as desirable
to perfect the security interests in fixtures purported to be created by the Mortgages in favor of the Collateral Agent for its benefit and the benefit of the Trustee and the Second-Priority Secured Parties; provided, however, that to
the extent local counsel opines that any Mortgage would constitute a valid and effective fixture filing in the jurisdiction in which the applicable Mortgaged Property is located, a fixture filing on Form UCC-1
shall not be required with respect to such Mortgaged Property. 
 (v) Counsel Opinions. Opinions addressed to the
Initial Purchasers and the Collateral Agent for its benefit and for the benefit of the Trustee and the Second-Priority Secured Parties of (i) local counsel in each jurisdiction where the Mortgaged Property is located with respect to the
enforceability and perfection of the Mortgages and other matters customarily included in such opinions and (ii) counsel for the Company regarding due authorization, execution and delivery of the Mortgages. 

(vi) Collateral Fees and Expenses. Evidence of payment by the Company of all Mortgage Policy premiums, search and
examination charges, mortgage recording taxes, fees, charges, costs and expenses required for the recording of the Mortgages, fixture filings and other documents and issuance of the Mortgage Policies referred to above. 

Notwithstanding anything to the contrary, (x) for purposes of this Section 1506, “commercially reasonable efforts” shall
include the Company and the Guarantors taking any necessary ministerial actions to cure defects in title to the extent necessary to obtain a valid Mortgage and Mortgage Policy to the extent required by clauses (ii) and (iii) above, but shall
not include the payment of more than de minimis fees and expenses to cure any title defects, the payment of more than $200,000 for the procurement of the Mortgage Policies, and (y) no default under the Purchase Agreement, this Indenture
or any Security Document will be triggered if the Company fails to deliver a Mortgage or Mortgage Policy on one or more of the Mortgaged Properties in spite of its use of commercially reasonable efforts to do so. For the avoidance of doubt, the
requirements set forth in clauses (iv) to (vi) hereof shall not be required to be satisfied if the Company is not required to deliver a Mortgage or Mortgage Policy pursuant to this Section 1506. 

Prior to delivery of any of the documentation set forth above, the Collateral Agent shall have the opportunity to request and receive an
Officers’ Certificate of the Company certifying that such documentation (i) is in customary form, (ii) will cause no default under any Intercreditor Agreement or any other intercreditor agreement entered into in accordance with the
terms of this Indenture that is then in effect and (iii) is in compliance with the terms of this Indenture. 

  
 -110- 








 Neither the Collateral Agent nor the Trustee undertakes any responsibility whatsoever to
determine whether any of the foregoing covenants in this Section 1506 have been satisfied, and neither shall have any liability whatsoever arising out of the failure of the Company or any of the Guarantors to satisfy such post-closing
requirements. 
 ARTICLE SIXTEEN 

COLLATERAL ACCOUNT 

SECTION 1601. Collateral Account. Not later than ninety (90) days following the date hereof, there shall be established by the
Company with the First-Priority Collateral Agent or, no later than (90) ninety days following the Discharge of First Lien Obligations (as defined in the First Lien/Second Lien Intercreditor Agreement), the Collateral Agent and, at all times
thereafter until this Indenture shall have terminated, there shall be maintained a deposit account subject to control (within the meaning of the UCC) of the First-Priority Collateral Agent or, no later than (90) ninety days following the
Discharge of First Lien Obligations (as defined in the First Lien/Second Lien Intercreditor Agreement), the Collateral Agent (the “Collateral Account”). The Company shall apply any amounts in the Collateral Account pursuant this
Indenture and the Intercreditor Agreements. The Collateral Agent shall have no obligation to monitor the amounts deposited, held or withdrawn from the Collateral Account. Notwithstanding anything in this Indenture to the contrary, prior to the
Discharge of First Lien Obligations (as defined in the First Lien/Second Lien Intercreditor Agreement), the requirements of this Section 1601 with respect to the Collateral Account shall be deemed satisfied by satisfaction of a provision with
respect to a collateral account that exists in substantially the same form in the Term Loan Facility Documents. 
 Neither the Collateral
Agent nor the Trustee undertakes any responsibility whatsoever to determine whether any of the foregoing covenants in this Section 1601 have been satisfied and neither shall have any liability whatsoever arising out of the failure of the
Company or any of the Guarantors to satisfy such requirements.

the Distribution Compliance Period and then, after the expiration of the Distribution Compliance Period, may be exchanged for interests in a Rule 144A Global Note or the Permanent Regulation S Global Note only upon certification in the form attached

 The Rule 144A Global Note, the Temporary Regulation S Global Note and the Permanent Regulation S
Global Note are collectively referred to herein as “Global Notes.” The aggregate principal amount of the Global Notes 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 Note
deposited with or on behalf of the Depository. 
 The Company shall execute and the Trustee shall, in accordance with this
Section 2.1(b), authenticate and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depository or the nominee of the Depository and (b) shall be delivered by the Trustee to the Depository or
pursuant to the 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 the Indenture with respect to any Global Note held on their behalf by the Depository or by the Trustee as the custodian of the Depository or under such Global Note, 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 Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by 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 Note. 
 (c)
Certificated Notes. Except as provided in this Section 2.1 or Section 2.3 or 2.4, owners of beneficial interests in Global Notes shall not be entitled to receive physical delivery of Certificated Notes. 

2.2 Authentication. The Trustee shall upon receipt of a Company Order specified in Section 202 of the Indenture authenticate and
deliver: (1) on the Issue Date, an aggregate principal amount of $400,000,000 10.750% Senior Secured Junior Priority Notes due 2023 and (2) any Additional Notes for an original issue in an aggregate principal amount specified in the
written order of the Company pursuant to Section 202 of the Indenture, in each case upon a Company Order signed by two Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Company. Such Company Order
shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of any issuance of Additional Notes pursuant to Section 312 of the Indenture, shall certify that
such issuance is in compliance with Sections 1011 and 1012 of the Indenture. 
 2.3 Transfer and Exchange. 

(a) Transfer and Exchange of Certificated Notes. When Certificated Notes are presented to the Note Registrar with a request: 

(x) to register the transfer of such Certificated Notes; or 

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

 the Note Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met;
provided, however, that the Certificated Notes surrendered for transfer or exchange: 
 (i) shall be duly
endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Note Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 

  
 -3- 








 (ii) if such Certificated Notes are required to bear a restricted notes legend,
they are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional
information and documents, as applicable: 
 (A) if such Certificated Notes are being delivered to the Note 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 Certificated Notes are being transferred to the Company, a certification to that effect; or 

(C) if such Certificated Notes are being transferred (x) pursuant to an exemption from registration in accordance with
Rule 144A or Regulation S under the Securities Act or (y) in reliance upon another exemption from the requirements of the Securities Act: (i) a certification to that effect (in the form set forth on the reverse of the Note) and
(ii) if the Company so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.3(e)(i). 

(b) Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated Note may not be
exchanged for a beneficial interest in a Rule 144A Global Note or a Permanent Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Certificated Note, duly endorsed or accompanied by
appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 
 (i) certification, in a form
substantially similar to that attached hereto as Exhibit 2, that such Certificated Note is either (A) being transferred to a QIB in accordance with Rule 144A or (B) being transferred after expiration of the Distribution Compliance Period
by a Person who initially purchased such Note in reliance on Regulation S to a buyer who elects to hold its interest in such Note in the form of a beneficial interest in the Permanent Regulation S Global Note; and 

(ii) written instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books
and records with respect to such Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)) or Permanent Regulation S Global Note (in the case of a transfer pursuant to clause (b)(i)(B)) to reflect an increase in the aggregate
principal amount of the Notes represented by the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase, 

then the Trustee shall cancel such Certificated Note and cause, or direct the Notes Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depository and the Notes Custodian, the aggregate principal amount of Notes represented by the Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, to be increased by the aggregate principal
amount of the Certificated Note to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Note or Permanent Regulation S Global Note, as
applicable, equal to the principal amount of the Certificated Note so canceled. If no Rule 144A Global Notes or Permanent Regulation S Global Notes, as applicable, are then outstanding, the Company shall issue and the Trustee shall authenticate,
upon receipt of a Company Order, a new Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, in the appropriate principal amount. 

(c) Transfer and Exchange of Global Notes. 

(i) The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with the
Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Note shall deliver to the Note Registrar a written order given in
accordance with the Depository’s procedures containing 

  
 -4- 








 
information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Note. The Note Registrar shall, in accordance with such instructions,
instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being
transferred. 
 (ii) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another
Global Note, the Note Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be
so transferred, and the Note Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note 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 Note may not be
transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee
of such successor Depository. 
 (iv) In the event that Global Note is exchanged for Certificated Notes pursuant to Section 2.4 of this
Appendix, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Notes (as
set forth in Exhibit 2, hereto) intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by
the Company. 
 (d) Restrictions on Transfer of Temporary Regulation S Global Notes. During the Distribution Compliance Period,
beneficial ownership interests in Temporary Regulation S Global Notes may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (i) to the Company, (ii) in an offshore transaction in accordance with
Regulation S (other than a transaction resulting in an exchange for an interest in a Permanent Regulation S Global Note), or (iii) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any
applicable securities laws of any State of the United States. 
 (e) Legend. 

Each Note certificate evidencing the Global Notes (and all Notes issued in exchange therefor or in substitution thereof) shall bear a legend
in substantially the following form: 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER
(1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH
RULE 904 UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO ALERIS INTERNATIONAL, INC. (THE “COMPANY”) OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A
QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (D) IN ACCORDANCE WITH AN EXEMPTION FROM
THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OTHER THAN RULE 144 (AND BASED UPON AN OPINION OF COUNSEL IF THE COMPANY SO REQUESTS) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT
IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE 

  
 -5- 








 
TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. NOTWITHSTANDING ANYTHING TO
THE CONTRARY, TRANSFERS PURSUANT TO RULE 144 WILL NOT BE PERMITTED, EVEN IF LEGALLY AVAILABLE. 
 Each certificate evidencing a Note offered
in reliance on Regulation S shall, in addition to the foregoing, bear a legend in substantially the following form: 
 THIS
SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR
BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE
SECURITIES ACT. 
 Each Certificated Note shall also bear the following additional legend: 

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE NOTE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS. 
 (f)
Cancellation or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have been exchanged for Certificated Notes, redeemed, purchased or canceled, such Global Note 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 Note is exchanged for certificated Notes, redeemed, purchased or canceled, the principal amount of Notes represented
by such Global Note shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes 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 Note, 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 Notes 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 Notes. All notices and communications to be given to the Holders and
all payments to be made to Holders under the Notes 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 Note). The rights of beneficial owners in any Global
Note shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information 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

 [FORM OF REVERSE SIDE OF INITIAL NOTE] 

10.750% Senior Secured Junior Priority Note due 2023 

Capitalized terms used herein but not defined herein shall have the meanings given to such terms in the Indenture. 

1. Principal and Interest. 
 Aleris
International, Inc. (the “Company”) shall pay the principal of this Note on July 15, 2023. 
 The Company promises to pay
interest on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate set forth below (subject to adjustment as provided below). 

Interest on the Notes shall accrue at the rate of 10.750% per annum and be payable in cash. 

Interest shall be payable semi-annually (to the Holders of the Notes at the close of business on January 1 or July 1 immediately
preceding the Interest Payment Date) on each Interest Payment Date, commencing January 15, 2019. 
 Interest on this Note shall accrue
from the most recent date to which interest has been paid or, if no interest has been paid, from June 25, 2018 (although any Additional Notes may accrue interest starting at other dates, and the first Interest Payment Date may be a different
date); provided that, if there is no existing Default in the payment of interest and if this Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. 

The Company shall pay interest on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent
lawful, at a rate per annum equal to the rate of interest applicable to the Notes. 
 2. Method of Payment. 

The Company shall pay interest (except Defaulted Interest) on the principal amount of the Notes on each January 15 and July 15 to the
Persons who are Holders (as reflected in the Note Register at the close of business on January 1 and July 1 immediately preceding the Interest Payment Date), in each case, even if the Note is transferred or exchanged after such Regular
Record Date, except as provided in Section 306(b) with respect to Defaulted Interest; provided that, with respect to the payment of principal, the Company shall make payment to the Holder that surrenders this Note to any Paying Agent on
or after July 15, 2023. 
 The Company shall pay principal, premium, if any, and interest in money of the United States that at the
time of payment is legal tender for payment of public and private debts. However, the Company may pay principal, premium, if any, and interest by its check payable in such money. The Company may pay interest on the Notes either (a) by mailing a
check for such interest to a Holder’s registered address (as reflected in the Note Register) or (b) by wire transfer to an account located in the United States maintained by the payee. If a payment date is a date other than a Business Day
at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period. 

3. Paying Agent and Note Registrar. 

Initially, U.S. Bank National Association (the “Trustee”) shall act as Paying Agent and Note Registrar. The Company may change any
Paying Agent or Note Registrar upon written notice thereto and without notice to the Holders. The Company, any Subsidiary or any Affiliate of any of them may act as Paying Agent, Note Registrar or
co-registrar. 

  
 -6- 








 4. Indenture. 

The Company issued the Notes under an Indenture dated as of June 25, 2018 (the “Indenture”), among the Company, the Guarantors,
the Trustee and the Collateral Agent. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of all such terms. In the event of any
inconsistency between (x) the terms of this Note and (y) the terms of the Indenture, the terms of the Indenture shall control. In the event of any inconsistency between (x) the terms of the Security Documents and (y) the terms of
this Note, the terms of the Security Documents shall control. 
 The Notes are senior secured obligations of the Company. The Indenture does
not limit the aggregate principal amount of the Notes. Subject to the conditions set forth in the Indenture, the Company may issue Additional Notes. 
 5.
Mandatory Redemption. 
 The Company is not required to make any mandatory redemption or sinking fund payments with respect to the
Notes. 
 6. Optional Redemption. 
 At
any time prior to July 15, 2020, the Company may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the
Applicable Premium as of, and accrued and unpaid interest, if any, to the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. 

From and after July 15, 2020, the Company may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’
prior notice at the Redemption Prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, thereon to the applicable 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 twelve-month period beginning on July 15 of each of the years indicated below: 

 

					
	 Year
	  	Percentage	 
	 2020
	  	 	104.000	% 
	 2021
	  	 	102.000	% 
	 2022 and thereafter
	  	 	100.000	% 

 Prior to July 15, 2020, the Company may, at its option, redeem up to 40% of the sum of the original
aggregate principal amount of Notes (and the original principal amount of any Additional Notes) issued under the Indenture at a redemption price equal to 110.750% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any,
thereon to the Redemption Date, subject to the right of Holders on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date, with funds in an amount equal to all or a portion of the net cash proceeds of one or
more Equity Offerings of the Company or any direct or indirect parent of the Company to the extent such net proceeds are contributed to the Company; provided that at least 60% of the sum of the aggregate principal amount of the Notes
originally issued under the Indenture and the aggregate principal amount of any Additional Notes issued under the Indenture after the Issue Date remain Outstanding immediately after the occurrence of each such redemption (unless all Notes
outstanding on the Redemption Date are redeemed); provided, further, each such redemption occurs within 180 days of the date of closing of each such Equity Offering. 

If a Change of Control occurs (x) at any time on or prior to July 15, 2019, the Company (or a third party on behalf of the Company)
may, at its option, redeem all, but not less than all, of the Notes, at a redemption price equal to 102.000% of the principal amount of the Notes and (y) at any time after July 15, 2019 but on or prior to July 15, 2020, the Company
(or a third party on behalf of the Company) may, at its option, redeem all, but not less than all, of the Notes, at a redemption price equal to 103.000% of the principal amount of the Notes, in each case, plus


  
 -7- 








 
accrued and unpaid interest, if any, thereon to the applicable Redemption Date, subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the
relevant Interest Payment Date (a “Change of Control Redemption”). If the Company (or such third party) elects to exercise this redemption right, it must do so by sending a redemption notice to each Holder with a copy to the Trustee within
30 days following the Change of Control (or, at the Company’s option, prior to such Change of Control but after the transaction giving rise to such Change of Control is publicly announced). Any such redemption may be conditioned upon the Change
of Control occurring if the notice is sent prior to the Change of Control. If the Company (or such third party) exercises the Change of Control Redemption right, the Company may elect not to make the Change of Control Offer pursuant to
Section 1017 unless it defaults in payments due upon redemption. 
 Upon consummation by the Company or any Restricted Subsidiary of
one or more Asset Sales generating Net Proceeds in excess of $35.0 million in the aggregate (x) at any time on or prior to July 15, 2019, the Company may, at its option, redeem all or a portion of the Notes in an aggregate principal
amount not to exceed such Net Proceeds, at a redemption price equal to 102.000% of the principal amount of the Notes and (y) at any time after July 15, 2019 but on or prior to July 15, 2020, the Company may, at its option, redeem all
or a portion of the Notes in an aggregate principal amount not to exceed such Net Proceeds, at a redemption price equal to 103.000% of the principal amount of the Notes, in each case, plus accrued and unpaid interest, if any, thereon to the
applicable Redemption Date, subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date (an “Asset Sale Redemption”). If the Company elects to exercise this
redemption right, it must do so by sending a notice of an Asset Sale Redemption at least 30 days prior to such Redemption Date to each Holder with a copy to the Trustee. Any such redemption may be conditioned upon the consummation of an Asset Sale
if the notice is sent prior to consummation of such Asset Sale. For the avoidance of doubt, any cash actually applied to redeem Notes pursuant to an Asset Sale Redemption shall be excluded from the calculation of Excess Proceeds and therefore the
requirement to make an Asset Sale Offer. 
 7. Repurchase upon a Change of Control, Asset Sales and Events of Loss. 

Subject to paragraph 6 above, upon the occurrence of (a) a Change of Control, the Holders shall have the right, pursuant to
Section 1017 of the Indenture, to require that the Company purchase such Holder’s Outstanding Notes, in whole or in part, at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of
purchase, (b) Asset Sales, the Company may be obligated, pursuant to Section 1018 of the Indenture, to make offers to purchase Notes and Other Second-Priority Obligations of the Company with a portion of the Net Proceeds of such Asset
Sales at a purchase price of 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase and (c) Events of Loss, the Company may be obligated, pursuant to Section 1020 of the Indenture, to make
offers to purchase Notes and Other Second-Priority Obligations of the Company with a portion of the Net Loss Proceeds of such Events of Loss at a purchase price of 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase. 
 8. Denominations; Transfer; Exchange. 

The Notes are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess
thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Note Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture. The Note Registrar need not register the transfer or exchange of a Note or portion of a Note selected for redemption (except, in the case of a Note to be redeemed in
part, the portion of the Note not to be redeemed) or any Note or portion of a Note for a period of 15 days before a selection of Notes to be redeemed or 15 days before an Interest Payment Date. 

9. Persons Deemed Owners. 
 A registered
Holder may be treated as the owner of a Note for all purposes. 

  
 -8- 








 10. Unclaimed Money. 

Subject to any laws relating to abandoned property, if money for the payment of principal, premium, if any, or interest remains unclaimed for
two years, the Trustee and the Paying Agent shall pay the money back to the Company at its request or (if then held by the Company) shall be discharged from such trust. After that, Holders entitled to the money must look to the Company for payment
and all liability of the Trustee and such Paying Agent with respect to such money, and all liability of the Company as trustee thereof, shall cease. 
 11.
Discharge and Defeasance Prior to Redemption or Maturity. 
 Subject to satisfaction of conditions set forth in the Indenture, the
Company and the Guarantors at any time may terminate their respective obligations under the Notes, the Notes Guarantees and the Indenture, whereupon all the Liens on and security interests in the Collateral securing the Indenture Obligations granted
under the Security Documents shall be automatically released, if the Company or any Guarantor irrevocably deposits with the Trustee cash or Government Securities or a combination thereof sufficient for the payment of the then outstanding principal
of and interest on the Notes to the applicable Redemption Date or Stated Maturity, as the case may be. 
 12. Amendment; Supplement; Waiver. 

The Indenture, the Notes, the Notes Guarantees and the Security Documents may be amended, supplemented or waived as provided in Article Nine of
the Indenture. 
 13. Restrictive Covenants. 

The Indenture contains certain covenants, including covenants with respect to the following matters: (i) Restricted Payments;
(ii) incurrence of Indebtedness and issuance of Disqualified Stock and Preferred Stock; (iii) Liens; (iv) transactions with Affiliates; (v) dividend and other payment restrictions affecting Restricted Subsidiaries;
(vi) guarantees of Indebtedness by Restricted Subsidiaries; (vii) changes to the terms of certain Subordinated Indebtedness; (viii) merger, consolidation or sale of all or substantially all assets; (ix) purchase of Notes upon a
Change of Control; (x) sale and lease-back transactions; (xi) disposition of proceeds of Asset Sales; and (xii) application of proceeds upon Events of Loss. Within 120 days after the end of each fiscal year beginning with the fiscal
year ending December 31, 2018, the Company must report to the Trustee on compliance with such limitations. 
 14. Successor Persons. 

When a successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor
Person shall be released from those obligations, subject to certain exceptions. 
 15. Remedies for Events of Default. 

If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount
of the Outstanding Notes may declare all Outstanding Notes to be immediately due and payable. If an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company occurs and is continuing, the Notes
automatically become immediately due and payable. Subject to the provisions of the Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any rights
or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Subject to certain restrictions, the Holders of
a majority in principal amount of the Outstanding Notes are given the right to 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. The
Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability.

 16. Notes Guarantees. 

The Company’s obligations under the Notes are fully, irrevocably and unconditionally guaranteed on a senior secured basis, to the extent
set forth in the Indenture, by each of the Guarantors. 
 17. Trustee Dealings with Company. 

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to,
accept deposits from, perform services for, and otherwise deal with, the Company and its Affiliates as if it were not the Trustee. 
 18.
Authentication. 
 This Note shall not be valid until the Trustee signs the certificate of authentication on the other side of this
Note. 
 19. Abbreviations. 
 Customary
abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and

 20. CUSIP and ISIN Numbers. 

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