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 Asset Acquisitions, dispositions, mergers,
consolidations and discontinued operations (and the change of any associated Fixed Charges and the change in Consolidated Adjusted EBITDA resulting therefrom) had occurred on the first day of the four–quarter reference period, including any pro
forma expense and cost reductions and other operating improvements that have occurred or are reasonably expected to occur, in the reasonable judgment of the chief financial officer of the Issuer (regardless of whether these cost savings or operating
improvements could then be reflected in pro forma financial statements in accordance with Regulation S–X promulgated under the Securities Act or any other regulation or policy of the SEC related thereto). Any Person that is a Restricted
Subsidiary on the Calculation Date will be deemed to have been a Restricted Subsidiary at all times during such four–quarter period, and if, since the beginning of the four–quarter reference period, any Person that subsequently became a

each case with respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be adjusted giving pro forma effect thereto for such period as if such Asset
Acquisition, disposition, discontinued operation, merger or consolidation had occurred at the beginning of the applicable four–quarter reference period. Any Person that is not a Restricted Subsidiary on the Calculation Date will be deemed not
to have been a Restricted Subsidiary at any time during such four–quarter period. 
 For purposes of this definition,
whenever pro forma effect is to be given to any transaction, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Issuer. If any Indebtedness bears a floating rate of interest and is being

Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capital Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the
Issuer to be the rate of interest implicit in such Capital Lease Obligation. 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 

  
 -17-








 
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 Issuer may designate. Any such pro forma calculation may include adjustments appropriate, in the reasonable determination of the Issuer as set
forth in an Officer’s Certificate, to reflect operating expense reductions reasonably expected to result from any acquisition or merger.

(2) the consolidated interest expense of such Person and its Restricted Subsidiaries that was capitalized during such

and Hedging (formerly SFAS 133) and related interpretations as a result of the terms of the Indebtedness to which such consolidated interest expense relate; plus 

(3) all cash dividend payments or other cash distributions on any series of preferred equity of such Person and all other

of $2,000 and integral multiples of $1,000 in excess of $2,000. 
 The terms and provisions contained in the Notes will
constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to

 (b) Global Notes. Notes issued in global form will be substantially in the form of Exhibits A1 or A2 hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of
Interests in the Global Note” attached thereto). Notes issued in definitive form 

  
 -47-








 
will be substantially in the form of Exhibit A1 hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached
thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the written direction of the Trustee, in accordance with instructions given by the Holder thereof as required by
Section 2.06 hereof. 
 (c) None of the Trustee or any Agent shall have any responsibility or obligation to any beneficial
owner of an interest in a Global Note, a member of, or a Participant or Indirect Participant in, the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Participant or Indirect

(including any notice of redemption) or the payment of any amount or delivery of any Notes (or other security or property) 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 in respect of the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary 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 Depositary subject to the Applicable Procedures of the Depositary. The Trustee and each Agent may conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its
members, Participants, Indirect Participants and any beneficial owners. Neither the Trustee nor any Agent shall have any responsibility or liability for actions take or not taken by the Depositary.

 (b) The Issuer will maintain an office or agency where Notes may be presented for registration of transfer or for exchange

appoint one or more co–registrars and one or more additional Paying Agents. The term “Registrar” includes any co–registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any
Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. The Issuer or any of the Issuer’s Subsidiaries may act as Paying Agent or

benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or interest on the Notes, and will notify the Trustee in writing of any default by the Issuer in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent
(if other than the Issuer or a Subsidiary of the Issuer) will have no further liability for the money. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the
Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes.

of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note

CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.” 

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note
have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with
Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or
for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an
endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (h) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Issuer will execute and the Trustee will authenticate Global
Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request.

exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Issuer, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (5) Neither the Registrar nor the Issuer will be required: 
 (A) to
issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes to be redeemed under Section 3.02 hereof or purchased pursuant to an

in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to

 Section 2.07 Replacement Notes. 

(a) If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder
that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in
replacing a Note. 
 (b) Every replacement Note is an additional obligation of the Issuer and will be entitled to all of the

it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer shall not be deemed to be outstanding for purposes of
Section 3.07(a) and Section 9.02(a) hereof.

hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 (c) If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

(d) If the Paying Agent (other than the Issuer, a Subsidiary of the Issuer or an Affiliate of any thereof) holds, on a redemption date or
maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 
 Section 2.09 Treasury Notes. 
 In determining whether the Holders of
the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control
with the Issuer or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible
Officer of the Trustee actually knows are so owned will be so disregarded. 

  
 -61-








 Section 2.10 Temporary Notes. 

(a) Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an
Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to
the Trustee. Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 (b) Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 

Section 2.11 Cancellation. 
 The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of such canceled Notes in its customary manner (subject to the record retention
requirement of the Exchange Act). Certification of the disposition of all canceled Notes will be delivered to the Issuer at the Issuer’s written request. The Issuer may not issue new Notes to replace Notes that it has paid or that have been
delivered to the Trustee for cancellation. 
 Section 2.12 Defaulted Interest. 

If the Issuer defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer will notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be
less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will
mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 Section 2.13 CUSIP Numbers. 
 The Issuer in issuing the Notes may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as
to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be
affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

8 or 11 hereof. 
 (b) The notice will identify the Notes (including CUSIP Numbers) to be redeemed and will state: 

(1) the redemption date; 
 (2) the redemption price; 
 (3) if any Note is being redeemed in
part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the
original Note; 
 (4) the name and address of the Trustee;

 (8) that no representation is made as to
the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and 

(9) if in connection with any conditional notice of redemption pursuant to Section 3.07 hereof, any condition to
the related redemption. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice of redemption shall describe each such condition, and if applicable, shall state that, in the Issuer’s
discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been
satisfied by the stated redemption date, or by the redemption date as so delayed. 
 (c) At the Issuer’s written request,
the Trustee will give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least 45 days prior to the redemption date, an Officer’s Certificate
requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(b). 

Section 3.04 Effect of Notice of Redemption.

provided for in Section 3.07(h) hereof. The notice, if mailed in accordance with Section 3.03 hereof, shall be conclusively presumed to have been given, 

  
 -64-








 
whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder designated for redemption in whole or in part shall not
affect the validity of the proceedings for the redemption of any other Note. 
 Section 3.05 Deposit of Redemption Price.

 (a) One Business Day prior to the redemption date, the Issuer will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in
excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. 
 (b) If the
Issuer complies with the provisions of Section 3.05(a), on and after the redemption date, interest will cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but
on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption is not so paid
upon surrender for redemption because of the failure of the Issuer to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest
not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

 (d) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the
Issuer or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. In the event that a Restricted Payment meets the criteria of more than one of the exceptions described in (1) through (20) above or is entitled
to be made pursuant to Section 4.05(a), Section 4.05(b)(1) or Section 4.05(b)(2), as applicable, the Issuer shall, in its sole discretion, classify such Restricted Payment (or portion thereof) on the date made or later reclassify such
Restricted Payment (or portion thereof) in any manner that complies with this Section 4.05.

encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness
was permitted by the terms of this Indenture to be incurred;

or assets of a Restricted Subsidiary of the Issuer that restricts distributions by that Restricted Subsidiary pending closing of the sale or other disposition; 
 (8) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a
whole, than those contained in the agreements governing the Indebtedness being refinanced; 
 (9) Liens permitted
to be incurred under Section 4.10 hereof that limit the right of the debtor to dispose of the assets securing such Indebtedness; 
 (10) provisions limiting the disposition or distribution of assets or property or transfer of Capital Stock in joint venture agreements, asset sale agreements, sale–leaseback agreements, stock sale
agreements, limited liability company organizational documents, and other similar agreements entered into in the ordinary course of business, consistent with past practice or with the approval of the Issuer’s Board of Directors, which

which such Unrestricted Subsidiary became a Restricted Subsidiary of the Issuer; provided that such agreement was not entered into in anticipation of the Unrestricted Subsidiary becoming a Restricted Subsidiary of the Issuer and any such
encumbrance or restriction does not extend to any assets or property of the Issuer or any Restricted Subsidiary other than the assets and property of such Unrestricted Subsidiary; 

(18) any encumbrance or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such

such encumbrance or restriction will not materially affect the Issuer’s ability to make principal or interest payments on the Notes, as determined in good faith by the Issuer, whose determination shall be conclusive; 

(19) provisions with respect to the receipt of a rebate on an operating lease until all obligations due to a lessor on
other operating leases are satisfied or other customary restrictions in respect of assets or contract rights acquired by a Restricted Subsidiary of the Issuer in connection with a Sale/Leaseback Transaction;

compliance with this Section 4.06, (i) the priority of any preferred stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on ordinary shares shall not be deemed a restriction
on the ability to make distributions on Capital Stock and (ii) the subordination of loans or advances made to the Issuer or a Restricted Subsidiary of the Issuer to other Indebtedness incurred by the Issuer or any such Restricted Subsidiary

 Section 4.07 Incurrence of Indebtedness and Issuance of Preferred Equity. 

(a) The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Issuer will not issue any Disqualified Stock and
will not permit any of its Restricted Subsidiaries to issue any shares of preferred equity; provided, however, that the Issuer may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Issuer or any
Restricted Subsidiary of the Issuer may incur Indebtedness (including Acquired Debt) or issue preferred equity, if on the date thereof the Fixed Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such preferred equity is issued, as the case may be, would have been at least 2.0 to 1.0,
determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred equity had been issued, as the case may be, at the
beginning of such four–quarter period; provided, further, that Restricted Subsidiaries of the Issuer that are not Guarantors may not incur Indebtedness or issue any shares of preferred equity if, after giving pro forma effect to
such incurrence or issuance (including a pro forma application of the net proceeds therefrom), Indebtedness or preferred equity at any one time outstanding and incurred by Restricted Subsidiaries of the Issuer that are not Guarantors pursuant to
this Section 4.07(a) shall exceed $50.0 million. 
 (b) The provisions of Section 4.07(a) hereof will not
prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
 (1) the incurrence under Credit Facilities by the Issuer or any of its Restricted Subsidiaries of Indebtedness and letters of credit and bankers’ acceptances thereunder in an aggregate principal
amount under this clause (1) (with letters of credit deemed to have a principal amount equal to the maximum potential liability of the Issuer and its Restricted Subsidiaries thereunder) not to exceed the greater of (x) $400.0 million and
(y) the Borrowing Base as of the date of incurrence of such Indebtedness outstanding at any one time; 
 (2)
the incurrence by the Issuer and its Restricted Subsidiaries of Indebtedness to the extent outstanding on the Issue Date; 
 (3) the incurrence by the Issuer and its Restricted Subsidiaries (including any future Guarantor) of Indebtedness represented by the Notes and the related Note Guarantees to be issued on the Issue Date;

 (4) Indebtedness (including Capitalized Lease Obligations), Disqualified Stock and preferred stock incurred by
the Issuer or any Restricted Subsidiary of the Issuer, to finance the purchase, lease, design, construction, installation, repair, replacement or improvement of property (real or personal) or equipment that is used or useful in a Permitted Business,
whether through the direct purchase of assets or the 

  
 -80-








 
Capital Stock of any Person owning such assets and Indebtedness arising from the conversion of the obligations of the Issuer or any Restricted Subsidiary of the Issuer under or pursuant to any
“synthetic lease” transactions to on-balance sheet Indebtedness of the Issuer or such Restricted Subsidiary, in an aggregate principal amount which, when aggregated with the principal amount of all other Indebtedness, Disqualified Stock
and preferred stock incurred pursuant to this clause (4), does not exceed the greater of (x) $40.0 million and (y) 5.0% of Total Assets at the time of incurrence; provided that Capitalized Lease Obligations incurred by the Issuer or
any Restricted Subsidiary of the Issuer pursuant to this clause (4) in connection with a Sale/Leaseback Transaction shall not be subject to the foregoing limitation so long as the proceeds of such Sale/Leaseback Transaction are used by the
Issuer or such Restricted Subsidiary to permanently repay outstanding Indebtedness of the Issuer and the Restricted Subsidiaries; 
 (5) the incurrence by the Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace,
defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.07(a) hereof or clauses (2), (3), (4), (5), (12), (16) or (17) of this
Section 4.07(b); 
 (6) the incurrence by the Issuer or any of its Restricted Subsidiaries of intercompany
Indebtedness and cash management pooling obligations and arrangements between or among the Issuer and any of its Restricted Subsidiaries; provided, however, that: 

(A) if the Issuer or any Guarantor is the obligor on such Indebtedness (other than cash management pooling obligations)
and the payee is not the Issuer or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Issuer, or the Note Guarantee, in the
case of a Guarantor; and 
 (B) (i) any subsequent issuance or transfer of Equity Interests that results in
any such Indebtedness being held by a Person other than the Issuer or a Restricted Subsidiary of the Issuer, and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Issuer or a Restricted Subsidiary of
the Issuer, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

(7) the issuance by any of the Issuer’s Restricted Subsidiaries to the Issuer or to any of its Restricted
Subsidiaries of shares of preferred equity; provided, however, that: 
 (A) any subsequent issuance
or transfer of Equity Interests that results in any such preferred equity being held by a Person other than the Issuer or a Restricted Subsidiary of the Issuer, and 

  
 -81-








 (B) any sale or other transfer of any such preferred equity to a Person that
is not either the Issuer or a Restricted Subsidiary of the Issuer, 
 will be deemed, in each case, to constitute an issuance of
such preferred equity by such Restricted Subsidiary that was not permitted by this clause (7); 
 (8) the
incurrence by the Issuer or any of its Restricted Subsidiaries of Hedging Obligations other than for speculative purposes; 
 (9) the Guarantee by the Issuer or any of its Restricted Subsidiaries of Indebtedness and cash management pooling obligations and arrangements of the Issuer or a Restricted Subsidiary of the Issuer that
was permitted to be incurred by another provision of this Section 4.07 (including Section 4.07(a) hereof); provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the
Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (10) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, payment obligations in connection with health or other types of
social security benefits, unemployment or other insurance or self–insurance obligations, reclamation, statutory obligations, bankers’ acceptances, bid, performance, surety or similar bonds and letters of credit or completion or performance
guarantees (including without limitation, performance guarantees pursuant to flying contracts, supply agreements or equipment leases), or other similar obligations in the ordinary course of business or consistent with past practice; 

(11) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a
bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds; 
 (12) Indebtedness, Disqualified Stock or preferred equity of the Issuer or any Restricted Subsidiary of the Issuer incurred or issued to finance an acquisition or of Persons that are acquired by the
Issuer or any of its Restricted Subsidiaries or merged into a Restricted Subsidiary of the Issuer in accordance with the terms of this Indenture; provided, however, that for any such indebtedness outstanding under this clause
(12) in excess of $40.0 million, after giving effect to such acquisition and the incurrence of such Indebtedness, Disqualified Stock and preferred equity either: 

(A) the Issuer would be permitted to incur at least $1.00 of additional Indebtedness pursuant to Section 4.07(a)
hereof; or 
 (B) the Fixed Charge Coverage Ratio would not be less than immediately prior to such acquisition;

 (13) Indebtedness incurred by a Receivables Subsidiary in a Qualified Receivables Financing that is not
recourse to the Issuer or any Restricted Subsidiary of the Issuer other than a Receivables Subsidiary (except for Standard Securitization Undertakings); 

  
 -82-








 (14) the incurrence of Indebtedness arising from agreements of the Issuer or
a Restricted Subsidiary of the Issuer providing for indemnification, adjustment of purchase price, earn outs, or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or a
Subsidiary in accordance with the terms of this Indenture, other than Guarantees of Indebtedness incurred or assumed by any Person acquiring all or any portion of such business, assets or Subsidiary for the purpose of financing such acquisition;

 (15) the incurrence by the Issuer or any of its Restricted Subsidiaries of additional Indebtedness or the
issuance of Disqualified Stock or preferred equity in an aggregate principal amount (or accreted value, as applicable) or having an aggregate liquidation preference at any time outstanding not to exceed the greater of (x) $100.0 million and
(y) 7.5% of Total Assets (it being understood that any Indebtedness, Disqualified Stock or preferred equity incurred pursuant to this clause (15) shall cease to be deemed incurred or outstanding for purposes of this Section 4.07 from
and after the date on which the Issuer could have incurred such Indebtedness or Disqualified Stock or preferred equity under Section 4.07(a) hereof without reliance upon this clause (15)); 

(16) Contribution Indebtedness; 
 (17) Indebtedness of Restricted Subsidiaries of the Issuer that are not Guarantors in an amount not to exceed, in the aggregate at any one time outstanding the greater of (x) $40.0 million and

under Section 4.07(a) from and after the first date on which such Restricted Subsidiary could have incurred such Indebtedness under Section 4.07(a) without reliance on this clause (17)); 

(18) any “bad boy”, or springing recourse, Guarantee by the Issuer or any Restricted Subsidiary of the Issuer
that is the parent of an MTBE Subsidiary or Permitted MTBE Joint Venture of Indebtedness of an MTBE Subsidiary or Permitted MTBE Joint Venture so long as such Indebtedness (x) is incurred by such MTBE Subsidiary or Permitted MTBE Joint Venture
in connection with its ownership, development, use or operation of its MTBE Assets and (y) such Indebtedness is otherwise non-recourse to the Issuer and its Restricted Subsidiaries (other than any MTBE Subsidiary); 

(19) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in connection with the MLP

 (20) Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer supported by a letter of credit or bank guarantee issued pursuant to a Credit Facility, in a principal amount not in excess of
the stated amount of such letter of credit or bank guarantee; and 

  
 -83-








 (21) Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer
consisting of (x) the financing of insurance premiums or (y) take or pay obligations contained in supply arrangements, in each case, in the ordinary course of business. 

(c) The Issuer will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is
contractually subordinated in right of payment to any other Indebtedness of the Issuer or such Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially
identical terms; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured on a first or
junior Lien basis. 
 (d) For purposes of determining compliance with this Section 4.07, in the event that an item of
proposed Indebtedness, Disqualified Stock or preferred equity meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (21) above or is entitled to be incurred pursuant to
Section 4.07(a) hereof, the Issuer will be permitted to classify such item of Indebtedness, Disqualified Stock or preferred equity on the date of its incurrence and will only be required to include the amount and type of such Indebtedness,
Disqualified Stock or preferred equity in one of the above clauses, although the Issuer may divide and classify an item of Indebtedness, Disqualified Stock or preferred equity in one or more of the types of Indebtedness, Disqualified Stock or
preferred equity and may later reclassify all or a portion of such item of Indebtedness, Disqualified Stock or preferred equity, in any manner that complies with this Section 4.07. The accrual of interest or dividends, the accretion or
amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred equity as Indebtedness due to a change in accounting principles, the
payment of dividends on Disqualified Stock or preferred equity in the form of additional shares of the same class of Disqualified Stock or preferred equity and unrealized losses or charges in respect of Hedging Obligations (including those resulting
from the application of Standards Codification No. 815—Derivatives and Hedging (formerly SFAS 133)) will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred equity for purposes of this
Section 4.07; provided, in each such case (other than preferred stock that is not Disqualified Stock), that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Issuer as accrued. Notwithstanding any
other provision of this Section 4.07, the maximum amount of Indebtedness that the Issuer or any Restricted Subsidiary of the Issuer may incur pursuant to this Section 4.07 shall not be deemed to be exceeded solely as a result of
fluctuations in exchange rates or currency values. 
 (e) For purposes of determining compliance with any U.S. dollar
denominated restriction on the incurrence of Indebtedness where the Indebtedness incurred is denominated in a different currency, the amount of such Indebtedness will be the U.S. Dollar Equivalent determined on the date of the establishment of
the facility or instrument under which such Indebtedness was incurred; provided, however, that if such Indebtedness denominated in a different currency is subject to a Currency Agreement with respect to U.S. dollars, covering all
principal, premium, if any, and interest payable on such Indebtedness, the amount of such Indebtedness expressed in U.S. dollars will be as provided in such Currency Agreement. The principal amount of any refinancing Indebtedness incurred in the
same currency as the 

  
 -84-








 
Indebtedness being refinanced will be the U.S. Dollar Equivalent of the Indebtedness refinanced, except to the extent that (i) such U.S. Dollar Equivalent was determined based on a
Currency Agreement, in which case the refinancing Indebtedness will be determined in accordance with the preceding sentence, and (ii) the principal amount of the refinancing Indebtedness exceeds the principal amount of the Indebtedness being
refinanced, in which case the U.S. Dollar Equivalent of such excess, as appropriate, will be determined on the date such refinancing Indebtedness is incurred. 
 (f) The amount of any Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; (2) the principal amount of the Indebtedness, in the case of any other Indebtedness;
and 
 (2) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person,
the lesser of: 
 (A) the Fair Market Value of such assets at the date of determination; and 

(B) the amount of the Indebtedness of the other Person. 
 Section 4.08 Asset Sales. 
 (a) The Issuer will not, and will not
permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Issuer (or the
Restricted Subsidiary of the Issuer, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale)
of the assets or Equity Interests issued or sold or otherwise disposed of; 
 (2) except in the case of a
Permitted Asset Swap, at least 75% of the aggregate consideration received from such Asset Sale and all other Asset Sales since the Issue Date, on a cumulative basis, by the Issuer or such Restricted Subsidiary is in the form of cash, Cash
Equivalents, Marketable Securities or Additional Assets, or any combination thereof. For purposes of this provision, each of the following shall be deemed to be cash: 

(A) any liabilities of the Issuer or any Restricted Subsidiary of the Issuer (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets and as a result of which the Issuer or such Restricted Subsidiary is released from further liability;

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


  
 -85-








 (C) any Designated Non–cash Consideration received by the Issuer or any
of its Restricted Subsidiaries in such Asset Sale; provided that the aggregate Fair Market Value of such Designated Non–cash Consideration, taken together with the Fair Market Value at the time of receipt of all other Designated
Non–cash Consideration received pursuant to this clause (C) less the amount of Net Proceeds previously realized in cash from prior Designated Non–cash Consideration is less than the greater of (x) $40.0 million and (y) 5.0%
of Total Assets at the time of the receipt of such Designated Non–cash Consideration (with the Fair Market Value of each item of Designated Non–cash Consideration being measured at the time received and without giving effect to subsequent
changes in value); and 
 (D) accounts receivable of a business retained by the Issuer or any of its Restricted
Subsidiaries, as the case may be, following the sale of such business; provided that such accounts receivable (i) are not past due more than 90 days and (ii) do not have a payment date greater than 120 days from the date of the
invoices creating such accounts receivable; and 
 (E) any Capital Stock or assets of the kind referred to in
Section 4.08(b)(1)(F), (G) or (H). 
 (3) if such Asset Sale involves the disposition of Collateral,
the Issuer or such Restricted Subsidiary has complied with the provisions of this Indenture and the Security Documents; and 
 (4) if such Asset Sale involves the disposition of Notes Priority Collateral or, after the discharge of ABL Obligations, the disposition of ABL Priority Collateral, the Net Proceeds thereof shall be
delivered to the Collateral Agent for deposit into the Collateral Account, and, if any property other than cash or Cash Equivalents is included in such Net Proceeds, such property shall be made subject to the Note Liens. 

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

(A) to the extent such Net Proceeds constitute proceeds from the sale of ABL Priority Collateral, to repay Indebtedness
under the Credit Agreement secured by such ABL Priority Collateral; 
 (B) to the extent such Net Proceeds
constitute proceeds from the sale of Notes Priority Collateral, to permanently repay, equally and ratably, the Notes and any Permitted Additional Pari Passu Obligations; 

(C) if the assets subject of such Asset Sale do not constitute Collateral, but constitute collateral for other pari passu
Indebtedness, which Lien is permitted by this Indenture, to reduce Obligations under such other pari passu Indebtedness that is secured by such Lien (provided that such reduction, in the case of revolving credit Indebtedness, correspondingly and
permanently reduces commitments thereunder); 

  
 -86-








 (D) if the assets subject of such Asset Sale do not constitute Collateral or
collateral for any pari passu Indebtedness, to permanently reduce (or offer to reduce) Obligations under the Notes and other pari passu Indebtedness (and to correspondingly and permanently reduce commitments with respect thereto), provided that the
Issuer shall equally and ratably reduce Obligations under the Notes and any Pari Passu Payment Lien Obligations on a pro rata basis, provided that all reductions of or offers to reduce Obligations under the Notes shall be made pursuant to and in
compliance with Section 3.07 or through open–market purchases (to the extent such purchases are at or above 100.0% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for an Asset Sale
Offer) to all Holders to purchase their Notes at 100.0% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes to be repurchased; 

(E) if the assets subject of such Asset Sale are the property or assets of a Restricted Subsidiary of the Issuer that is
not a Guarantor, to permanently reduce Indebtedness of such Restricted Subsidiary (and to correspondingly and permanently reduce commitments with respect thereto), other than Indebtedness owed to the Issuer or another Restricted Subsidiary of the
Issuer; 
 (F) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted
Business; provided, that in the case of any such acquisition of Capital Stock, such Person is or becomes a Restricted Subsidiary of the Issuer; 
 (G) to acquire other short– or long–term assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business; or 

(H) to invest in Additional Assets; or 

(2) enter into a binding commitment to apply the Net Proceeds pursuant to Section 4.08(b)(1)(F), (G) or (H),
provided that such binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment until the earlier of (x) the date on which such acquisition or expenditure is consummated, and
(y) the 180th day following the expiration of the aforementioned 365 day period. 
 In the case of
Section 4.08(b)(1)(F), (G) and (H), the assets acquired with the Net Proceeds from an Asset Sale of assets constituting Collateral (or assets received in exchange therefor pursuant to Section 4.08(a)(2)) shall be pledged as
Collateral under the Security Documents (except that the aggregate Net Proceeds from Asset Sales of assets constituting Collateral (or assets received in exchange therefor pursuant to Section 4.08(a)(2)), taken together with all other Net
Proceeds from Asset Sales of assets constituting Collateral (or assets received in exchange therefor pursuant to Section 4.08(a)(2)) previously excluded, may be excluded from this requirement in an aggregate amount not to exceed the greater of
(x) $40.0 million and (y) 5.0% of Total Assets at the time of the receipt of such Net Proceeds or such exchange. 

  
 -87-








 (c) Pending the final application of any Net Proceeds, the Issuer may temporarily reduce
revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 
 (d)
Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.08(b) will constitute “Excess Proceeds.” Not later than the 366th day (or such later date as permitted by Section 4.08(b)(2))
from the later of the date of such Asset Sale or the receipt of such Net Proceeds, if the aggregate amount of Excess Proceeds exceeds $25.0 million, within ten Business Days thereof, the Issuer will make an offer to all Holders of Notes (an
“Asset Sale Offer”) and (x) in the case of Net Proceeds from Notes Priority Collateral, to the holders of any other Permitted Additional Pari Passu Obligations containing provisions similar to those set forth in this Indenture
with respect to offers to purchase or redeem with the proceeds of sales of assets or (y) in the case of any other Net Proceeds, to all holders of other Pari Passu Payment Lien Obligations containing provisions similar to those set forth in this
Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and Permitted Additional Pari Passu Obligations or other Pari Passu Payment Lien Obligations, as
appropriate, that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to, but excluding, the date of purchase and will be
payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer or any Restricted Subsidiary of the Issuer may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the
aggregate principal amount of Notes and Permitted Additional Pari Passu Obligations or other Pari Passu Payment Lien Obligations, as appropriate, tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the
Notes to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 (e) The Issuer will comply with the requirements of Rule 14e–1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable
in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Issuer will comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such compliance. 

(f) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided above, the Issuer
shall deliver to the Trustee an Officer’s Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the
compliance of such allocation with the provisions of this Section 4.08. Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer Period”), the Issuer shall deliver to the Trustee for
cancellation the Notes or portions thereof that have been properly tendered to and are to be accepted by the Issuer. No later than one Business Day preceding any date of purchase, the Issuer shall deposit with the Trustee (or a Paying Agent, if not
the Trustee) the purchase price for the tendered Notes and the Trustee (or a Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering Holder in


  
 -88-








 
the amount of the purchase price. In the event that the Excess Proceeds delivered by the Issuer to the Trustee is greater than the purchase price of the Notes tendered, the Trustee shall deliver
the excess to the Issuer immediately after the expiration of the Offer Period for application in accordance with this Section 4.08. 
 (g) Holders electing to have a Note purchased shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Note duly completed, to the
Issuer at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Trustee or the Issuer receives not later than one Business Day prior to the purchase
date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered by the Holder for purchase and a statement that such Holder is withdrawing his election to have such
Note purchased. If at the end of the Offer Period more Notes are tendered pursuant to an Asset Sale Offer than the Issuer is required to purchase, selection of such Notes for purchase shall be made by the Trustee in compliance with the requirements
of the principal national securities exchange, if any, on which such Notes are listed, or if such Notes are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as
complies with applicable legal requirements); provided that no Notes of $2,000 or less shall be purchased in part. 
 (h)
Notices of an Asset Sale Offer shall be mailed by the Issuer by first class mail, postage prepaid, at least 30 but not more than 60 days before the purchase date to each Holder at such Holder’s registered address. If any Note is to be purchased
in part only, any notice of purchase that relates to such Security shall state the portion of the principal amount thereof that is to be purchased. 
 (i) A new Note in principal amount equal to the unpurchased portion of any Note purchased in part shall be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the
purchase date, unless the Issuer defaults in payment of the purchase price, interest shall cease to accrue on Notes or portions thereof purchased. 
 Section 4.09 Transactions with Affiliates. 
 (a) The Issuer will not,
and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any
transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Issuer (each, an “Affiliate Transaction”), involving aggregate consideration in excess of $10.0 million,
unless: 
 (1) the Affiliate Transaction is on terms that are not materially less favorable to the Issuer or the
relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person; and 

(2) the Issuer delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $40.0 million, a resolution of the Board of Directors of the Issuer certifying that 

  
 -89-








 
such Affiliate Transaction complies with this Section 4.09 and that such Affiliate Transaction has been approved by a majority of the disinterested members, if any, of the Board of Directors
of the Issuer. 
 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to
the provisions of Section 4.09(a) hereof: 
 (1) any employment agreement, employee benefit plan,
officer or director indemnification agreement or any similar arrangement entered into by the Issuer or any of its Restricted Subsidiaries in the ordinary course of business or consistent with past practice and payments pursuant thereto; 

(2) transactions (including a merger) between or among the Issuer and/or any of its Restricted Subsidiaries; 

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Issuer) that is an Affiliate of the Issuer
solely because the Issuer owns, directly or through a Restricted Subsidiary of the Issuer, an Equity Interest in, or controls, such Person; 
 (4) payment of reasonable fees to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Issuer or any of its Restricted Subsidiaries or any direct or indirect parent
of the Issuer; 
 (5) any contribution to the capital of the Issuer or any issuance of Equity Interests (other

(6) Restricted Payments and Investments that do not violate Section 4.05 hereof; 

(7) the entering into any agreement to pay, and the payment of, customary annual management, consulting, monitoring and
advisory fees to the Equity Investors in an amount not to exceed in any four quarter period the greater of (x) $2.5 million and (y) 1.0% of Consolidated Adjusted EBITDA of the Issuer and its Restricted Subsidiaries for such period and
related expenses; 
 (8) loans or advances to employees or consultants in the ordinary course of business or
consistent with past practice; 
 (9) any transaction effected as part of a Qualified Receivables Financing;

 (10) any transaction in which the Issuer or any of its Restricted Subsidiaries, as the case may be, delivers
to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Issuer or such Restricted Subsidiary from a financial point of view or that such transaction meets the
requirements of clause (1) of Section 4.09(a); 
 (11) the existence of, or the performance by the
Issuer or any of its Restricted Subsidiaries of its obligations under the terms of, any acquisition agreements or members’ or stockholders’ agreement or related documents to which it is a party as of the Issue Date and any amendment
thereto or similar agreements which it may enter 

  
 -90-








 
into thereafter; provided, however, that the existence of, or the performance by the Issuer or any of its Restricted Subsidiaries of its obligations under, any future amendment to
any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (11) to the extent that the terms of any such existing agreement, together with all amendments thereto, taken as
a whole, or such new agreement are not otherwise more disadvantageous to the Holders taken as a whole than the original agreement as in effect on the Issue Date; 

(12) transactions with Unrestricted Subsidiaries, customers, clients, suppliers, joint ventures, joint venture partners or
purchasers or sellers of goods or services or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are, in the aggregate (taking into account all the costs
and benefits associated with such transactions), materially no less favorable to the Issuer or its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an
unrelated Person, in the reasonable determination of the Board of Directors of the Issuer or senior management of either of them, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

 (13) (x) guarantees of performance by the Issuer and its Restricted Subsidiaries of Unrestricted
Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (y) pledges of Equity Interests of Unrestricted Subsidiaries for the benefit of lenders of Unrestricted Subsidiaries;

 (14) if such Affiliate Transaction is with a Person in its capacity as a holder of Indebtedness or Capital
Stock of the Issuer or any Restricted Subsidiary of the Issuer where such Person is treated no more favorably than the holders of Indebtedness or Capital Stock of the Issuer or any Restricted Subsidiary of the Issuer; 

(15) transactions effected pursuant to agreements in effect on the Issue Date and any amendment, modification or
replacement of such agreement (so long as such amendment or replacement is not materially more disadvantageous to the Holders, taken as a whole); 
 (16) payments to the Equity Investors made for any financial advisory, financing or other investment banking activities, including without limitation, in connection with acquisitions or divestitures,
which payments are approved by a majority of the Board of Directors; 
 (17) the Transactions and the payment of

 -91-








 (21) transactions with any MLP Subsidiary if approved by the MLP’s
conflicts committee; and 
 (22) transactions between the Issuer or any of its Restricted Subsidiaries and any
Person, a director of which is also a director of the Issuer; provided, however, that such director abstains from voting as a director of the Issuer on any matter involving such other Person. 

Section 4.10 Liens. 

(a) The Issuer will not, and will not permit any Restricted Subsidiary of the Issuer to, directly or indirectly, create, incur or assume
any Lien (other than Permitted Liens) on any asset or property of the Issuer or such Restricted Subsidiary that secures any Indebtedness of the Issuer or such Restricted Subsidiary or any related Guarantees, except that the Issuer and any Restricted
Subsidiary of the Issuer may incur or suffer to exist Liens on assets not constituting Collateral, so long as the Issuer or such Restricted Subsidiary effectively provides that the Notes or the applicable Note Guarantee, as the case may be, shall be
equally and ratably secured with (or on a senior basis to, in the case such Lien secures any Indebtedness that is contractually subordinated in right of payment to the Notes or the applicable Note Guarantee) the Indebtedness or related Guarantees
secured by such Lien. 
 (b) Section 4.10(a) will not require the Issuer or any Restricted Subsidiary of the Issuer to
secure the Notes if the relevant Lien consists of a Permitted Lien. Any Lien which is granted to secure the Notes or such Note Guarantee under Section 4.10(a) shall be automatically released and discharged at the same time as the release of the
Lien that gave rise to the obligation to secure the Notes or such Note Guarantee under Section 4.10(a). 
 Section 4.11 Business
Activities. 
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other
than Permitted Businesses, except to such extent as would not be material to the Issuer and its Restricted Subsidiaries taken as a whole. 

Section 4.12 Offer to Repurchase Upon Change of Control. 
 (a) Upon the occurrence of a Change of Control, the Issuer will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral
multiple of $1,000 in excess of $2,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to, but not
including, the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of
Control, except to the extent that the Issuer has exercised its right to redeem the Notes in accordance with Article 3 of this Indenture, the Issuer will mail a notice to each Holder describing the transaction or transactions that constitute the
Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to this
Section 4.12 and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment; 

  
 -92-








 (2) the purchase price and the purchase date, which shall be no earlier than
30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not tendered will continue to accrue interest; 

(4) that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender
the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book–entry transfer, to the Trustee at the address specified in the notice prior to the close of business on the
third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders will be entitled to withdraw
their election if the Trustee receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be
equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000. 
 The Issuer will comply with the
requirements of Rule 14e–1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of
Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.12 hereof, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have
breached its obligations under this Section 4.12 by virtue of such compliance. 
 (b) On the Business Day immediately
preceding the Change of Control Payment Date, the Issuer will, to the extent lawful, deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes accepted for payment. 

  
 -93-








 (c) On the Change of Control Payment Date, the Issuer will, to the extent lawful:

 (1) accept for payment all Notes or portions of Notes (in a minimum principal amount of $2,000 and integral
multiples of $1,000 in excess of $2,000) properly tendered pursuant to the Change of Control Offer and not properly withdrawn; and 
 (2) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being
purchased by the Issuer. 
 The Paying Agent will promptly mail to each Holder properly tendered the Change of Control Payment
for such Notes, and the Trustee, upon receipt of an Authentication Order, will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided, that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as
reasonably practicable after the Change of Control Payment Date. 
 (d) If Holders of not less than 90% in aggregate principal
amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuer, or any other Person making a Change of Control Offer in lieu of the Issuer as described below, purchases all of the Notes
validly tendered and not withdrawn by such Holders, the Issuer shall have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer
described above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and
unpaid interest, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). 

(e) Notwithstanding anything to the contrary in this Section 4.12, the Issuer will not be required to make a Change of Control Offer
upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.12 and purchases all Notes properly tendered and not
withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption price. 

(f) The Issuer’s obligation to make a Change of Control Offer pursuant to this Section 4.12 may be waived or modified or
terminated with the written consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes) prior to the occurrence of such Change
of Control. 
 Section 4.13 Payments for Consent. 
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any cash consideration to or for the benefit of any Holder for any consent,
waiver or amendment of any of the terms or provisions of this Indenture, 

  
 -94-








 
the Notes, or the Security Documents unless such consideration is offered to be paid and is paid to all Holders that are QIBs and that consent, waive or agree to amend in the time frame set forth
in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.14 Additional Note Guarantees. 

If the Issuer or any of its Restricted Subsidiaries acquires or creates another Restricted Subsidiary of the Issuer that is a Domestic
Subsidiary after the Issue Date, then that newly acquired or created Restricted Subsidiary, if such Restricted Subsidiary Guarantees any Credit Facilities of the Issuer (unless such Restricted Subsidiary is a Receivables Subsidiary), will become a
Guarantor and execute a supplemental indenture substantially in the form of Exhibit D hereto and the applicable Security Documents or joinders or supplements thereto and deliver an Opinion of Counsel satisfactory to the Trustee within 30 days of the
date on which it was acquired or created; provided that this Section 4.14 shall not be applicable to any Guarantee of any Restricted Subsidiary of the Issuer that existed at the time such Person became a Restricted Subsidiary of the
Issuer and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary of the Issuer. 

Section 4.15 Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Board of Directors of the Issuer may designate any Restricted Subsidiary of the Issuer to be an Unrestricted Subsidiary if that
designation would not cause a Default. If a Restricted Subsidiary of the Issuer is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Issuer and its Restricted Subsidiaries in the
Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.05 hereof or under one or more clauses of
the definition of Permitted Investments, as determined by the Issuer. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors of the Issuer may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. 
 (b) Any designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors
giving effect to such designation and an Officer’s Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.05 hereof. If, at any time, any Unrestricted Subsidiary would fail to
meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary
of the Issuer as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.07 hereof, the Issuer will be in default of such covenant. The Board of Directors of the Issuer may at any time designate
any Unrestricted Subsidiary to be a Restricted Subsidiary of the Issuer; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Issuer of any outstanding Indebtedness of such
Unrestricted Subsidiary, and such designation will only be permitted if (1) (x) the Issuer could incur such Indebtedness 

  
 -95-








 
pursuant to Section 4.07(a) hereof, or (y) the Fixed Charge Coverage Ratio for the Issuer and its Restricted Subsidiaries would be equal to or greater than such ratio for the
Issuer and its Restricted Subsidiaries immediately prior to such designation, in each case on a pro forma basis taking into account such designation; and (2) no Default or Event of Default would be in existence following such designation.

 Section 4.16 Changes in Covenants upon Notes being Rated Investment Grade. 

(a) During any period of time and beginning on the day that (a) the Notes have an Investment Grade Rating and (b) no Default or
Event of Default has occurred and is continuing under this Indenture, the Issuer and its Restricted Subsidiaries will not be subject to the covenants contained in Sections 4.05, 4.06, 4.07, 4.08, 4.09, 4.11 and 4.15 hereof, and
Section 5.01(a)(4) shall terminate. If the Issuer and its Restricted Subsidiaries are not subject to these covenants for any period of time as a result of the previous sentence (a “Fall–Away Period”) and,
subsequently, the ratings assigned to the Notes are withdrawn or downgraded so the Notes no longer have an Investment Grade Rating or an Event of Default (other than with respect to a suspended covenant) occurs and is continuing, then the Issuer and
its Restricted Subsidiaries will thereafter again be subject to these covenants. The ability of the Issuer and its Restricted Subsidiaries to make Restricted Payments after the time of such withdrawal, downgrade or Event of Default will be
calculated as if the covenant governing Restricted Payments had been in effect during the entire period of time from the Issue Date. Notwithstanding the foregoing, the continued existence after the end of the Fall–Away Period of facts and
circumstances or obligations arising from transactions that occurred during a Fall–Away Period shall not constitute a breach of any covenant set forth in this Indenture or cause an Event of Default hereunder. 

(b) Neither the Trustee nor any Agent shall have any liability or responsibility with respect to, or obligation or duty to monitor,
determine or inquire (i) as to the Issuer’s or any Guarantor’s compliance with any covenant under this Indenture (other than the covenant to make payment on the Notes), (ii) as to whether or not the rating of the Notes has been
adjusted, or (iii) as to whether or not a Fall–Away Period has occurred or is continuing. 
 Section 4.17 Further Assurances,
Instruments and Acts. 
 (a) The Issuer shall execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 (b) The Issuer and the Guarantors
shall execute and deliver such additional instruments, certificates or documents, and take all such actions as may be reasonably required from time to time in order to: 

(1) carry out more effectively the purposes of the Security Documents; 

(2) create, grant, perfect and maintain the validity, effectiveness and priority of any of the Security Documents and the
Liens created, or intended to be created, by the Security Documents; and 

  
 -96-








 (3) ensure the protection and enforcement of any of the rights granted or
intended to be granted to the Trustee under any other instrument executed in connection therewith. 
 Section 4.18 Real Property.

 The Issuer shall notify the Collateral Agent in writing within 30 days after the acquisition of any real property owned by the
Issuer or any Guarantor that has a fair market value in excess of $5,000,000 that is not subject to the existing Mortgages (the “After–Acquired Real Property”), and, within 180 days after the acquisition of such owned real
property, as such date may be extended by the Collateral Agent, deliver to the Collateral Agent, with respect to such owned real property, each of the documents described in Section 4.19 hereof (but excluding the documents described in clause
(h) thereof) and such other documents as may be reasonably requested by the Collateral Agent to evidence the Liens contemplated by this Indenture and the Mortgages. 
 Section 4.19 Post-Closing Matters. 
 The Issuer and the Guarantors
shall deliver to the Collateral Agent within 180 days after the Closing Date, to the extent not previously provided, each of the following documents, which shall be reasonably satisfactory in form and substance to the Collateral Agent and its
counsel with respect to the Notes Priority Collateral, as appropriate:

Property, counterparts of a Mortgage, together with the assignments of leases and rents referred to therein, in proper form for recording in the appropriate recording office of the political subdivision where such Mortgaged Property is located, duly
executed and acknowledged by the Issuer or the applicable Guarantor effective to create a valid and enforceable first-priority (with respect to Notes Priority Collateral) mortgage Lien, subject to no Liens other than Permitted Liens, on each
Mortgaged Property, except to the extent such Mortgaged Property is located in a jurisdiction which imposes mortgage recording taxes, intangible taxes, documentary taxes or other similar fees and charges, the subject Mortgage shall only secure an
amount equal to the fair market value of such Mortgaged Property as reasonably determined, in good faith, by the Issuer and reasonably acceptable to the Collateral Agent, and such financing statements in respect of such Mortgage, any other
instruments necessary to grant the interests purported to be granted by such Mortgage (and to record such Mortgage in the appropriate recording offices) under the laws of any applicable jurisdiction. 

(b) Title Insurance. With respect to each Mortgage encumbering any Mortgaged Property, a policy of title insurance (or commitment

“Mortgage Policies”) issued by any title insurance company reasonably acceptable to the Collateral Agent (the “Title Company”), insuring (or committing to insure) that such Mortgage constitutes a valid and
enforceable first-priority (with respect to Notes Priority Collateral) mortgage Lien on the respective Mortgaged Property, free and clear of all Liens other than Permitted Liens, which Mortgage Policies shall (A) not include the general title
exception for mechanics’ liens, (B) provide for such affirmative insurance as the 

  
 -97-








 
Collateral Agent may reasonably request and which is available in the applicable jurisdiction at commercially reasonable rates and (C) otherwise be in form and substance reasonably
satisfactory to the Collateral Agent. 
 (c) Surveys. With respect to each Mortgaged Property, the Issuer shall deliver
either an as-built ALTA survey certified to the Collateral Agent for its benefit, for the benefit of the Trustee, for the benefit of the Holders and for the benefit of the Title Company prepared by an independent professional licensed land surveyor
or an affidavit of “no change” executed by the Issuer with respect to any existing survey, sufficient for the Title Company to delete the survey exception and issue a “same-as-survey” endorsement to the Mortgage Policies to the
extent such endorsement is available in the relevant jurisdiction at commercially reasonable rates. 
 (d) Fixture
Filings. With respect to each Mortgaged Property, to the extent the Mortgages are not sufficient to qualify as a fixture filing under applicable laws of the jurisdiction, a copy of a filed UCC-1 in the jurisdiction in which such Mortgaged
Property is located in order to perfect the Lien on and security interest in the fixtures encumbered by the applicable Mortgage in favor of the Collateral Agent for its benefit and the benefit of the Trustee and the Holders. 

(e) Flood Hazard Determinations and Insurance. With respect to each Mortgaged Property, subject to the Flood Insurance Laws (as
defined below), a “Life-of Loan” Federal Emergency Management Agency Standard Flood Hazard Determination and, if the area in which any Building (as defined in the Flood Insurance Laws) is located on any Mortgaged Property is designated a
“special flood hazard area” in any Flood Insurance Rate Map published by the Federal Emergency Management Agency (or any successor agency), a notice with respect to special flood hazard area status, duly executed by the Issuer and, to the
extent required, the applicable Subsidiary and evidence of flood insurance, naming the Collateral Agent for its benefit and the benefit of the Trustee and the Holders as mortgagee/loss payee to the extent (including with respect to amounts) required
in order to comply with the Flood Insurance Laws. “Flood Insurance Laws” means, collectively, (i) the National Flood Insurance Act of 1968 as now or hereafter in effect or any successor statute thereto, (ii) the Flood
Disaster Protection Act of 1973 as now or hereafter in effect or any successor statute thereto, (iii) the National Flood Insurance Reform Act of 1994 as now or hereafter in effect or any successor statute thereto and (iv) the Flood
Insurance Reform Act of 2004 as now or hereafter in effect or any successor statute thereto 
 (f) Title Insurance
Documents. With respect to each Mortgaged Property, such affidavits, certificates, information and instruments as shall be reasonably and customarily required to induce the Title Company to issue the Mortgage Policies.

another Holder.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and
interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired

to the Holders, to pay to the Trustee or the Collateral Agent any amount due to it for the reasonable and documented compensation, expenses, disbursements and advances of the Trustee or the Collateral Agent, their agents and counsel, and any other
amounts due the Trustee or the Collateral Agent under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee or the Collateral Agent, their agents and counsel, and any
other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the
Trustee or the Collateral Agent to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee or
the Collateral Agent to vote in respect of the claim of any Holder in any such proceeding.

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

time to time, for its acceptance and administration of this Indenture, the Intercreditor Agreement and/or the other the Security Documents and services hereunder. The Trustee’s and the Collateral Agent’s compensation will not be limited by
any law on compensation of a trustee of an express trust. The Issuer will reimburse each of the Trustee and the Collateral Agent promptly upon request for all reasonable and documented disbursements, advances and expenses incurred or made by it in
addition to the compensation for its services. Such expenses will include the reasonable and documented compensation, disbursements and expenses of each of the Trustee’s and the Collateral Agent’s agents and counsel. 

(b) The Issuer and each Guarantor, jointly and severally, will indemnify each of the Trustee and the Collateral Agent and hold each of
them harmless from and against any and all losses, liabilities, claims, damages, costs or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties or the exercise of its rights under this Indenture,
the Intercreditor Agreement and/or the other the Security Documents, including the reasonable and documented costs and expenses of enforcing this Indenture, the Intercreditor Agreement and/or the other the Security Documents against the Issuer and
the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its
powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its own gross negligence or willful misconduct. The Trustee or the Collateral Agent, as the case may be, will notify the Issuer promptly of
any claim of which it or a Responsible Officer has received written notice for which it may seek indemnity. Failure by the Trustee or the Collateral Agent, as the case may be, to so notify the Issuer will not relieve the Issuer or any of the
Guarantors of their obligations hereunder. 
 (c) The obligations of the Issuer and the Guarantors under this Section 7.07
will survive the satisfaction and discharge of this Indenture, the payment of the Notes and/or the resignation or removal of the Trustee or the Collateral Agent. 
 (d) To secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.07, each of the Trustee and the Collateral Agent will have a Lien prior to the Notes on all money or
property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture, the payment of the Notes and/or the resignation or
removal of the Trustee or the Collateral Agent. 
 (e) When the Trustee or the Collateral Agent incurs expenses or renders
services after an Event of Default specified in clause (6) or (7) of Section 6.01 hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law. 

  
 -111-








 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the
extent applicable. 
 Section 7.08 Replacement of Trustee. 
 (a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this
Section 7.08. 
 (b) The Trustee may resign at any time and be discharged from the trust hereby created by so notifying the
Issuer in writing. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing not less than 30 days prior to the effective date of such removal.
The Issuer may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof;

 (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the
Trustee under any Bankruptcy Law; 
 (3) a custodian or public officer takes charge of the Trustee or its
property; or 
 (4) the Trustee becomes incapable of acting. 

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer will promptly appoint
a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Issuer. 
 (d) If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the
retiring or removed Trustee, the Issuer, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may, at the expense of the Issuer, petition any court of competent jurisdiction for the appointment of a successor
Trustee. 
 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to
comply with Section 7.10 hereof, such Holder may petition at the expense of the Issuer any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

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

  
 -112-








 
paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under
Section 7.07 hereof will continue for the benefit of the retiring Trustee. 
 (g) The retiring Trustee shall have no
responsibility or liability for any action or inaction of a successor Trustee. 
 Section 7.09 Successor Trustee by Merger, etc.

 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business
(including this transaction) to, another corporation, the successor corporation without any further act will be the successor Trustee. 

Section 7.10 Eligibility; Disqualification. 
 There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws
to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of
condition. 
 This Indenture will always have a Trustee who satisfies the requirements of TIA § 310(a)(1),
(2) and (5). The Trustee is subject to TIA§ 310(b). 
 Section 7.11 Preferential Collection of Claims Against the
Issuer. 
 The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA
§ 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Issuer may at any time, at the option of the Issuer’s Board of Directors evidenced by a resolution set forth in an Officer’s
Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes and Note Guarantees upon compliance with the conditions set forth below in this Article 8. 

Section 8.02 Legal Defeasance and Discharge. 
 (a) Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and each of the Guarantors will, subject to the satisfaction of the
conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter,
“Legal 

  
 -113-








 
Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and
(2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuer, shall execute instruments acknowledging the same),
except for the following provisions which will survive until otherwise terminated or discharged hereunder: 
 (1)
the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.05 hereof; 

(2) the Issuer’s obligations with respect to such Notes under Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08,
2.09, 2.10 and Section 4.02 hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and the Issuer’s and the Guarantors’ obligations in connection therewith; and 
 (4) this
Article 8. 
 (b) Subject to compliance with this Article 8, the Issuer may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and each of
the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12,
4.13, 4.14, 4.15, 4.16, 4.17, 4.18 and 4.19 and Section 5.01(a)(3) and 5.01(a)(4) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with
such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that,
with respect to the outstanding Notes and Note Guarantees, the Issuer and the Guarantors may omit to comply with and will 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 with such covenants will not
constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified in this Section 8.03, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the
Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, clauses (3) through (5) of Section 6.01
hereof will not constitute Events of Default. 

  
 -114-

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

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars,
non–callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the case of non-callable Government Securities, in the written opinion of a U.S. nationally recognized investment bank, appraisal firm, or
firm of independent public accountants delivered to the Trustee, to pay the principal of, premium, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and
the Issuer must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date; 
 (2) in the case of an election under Section 8.02 hereof, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee (subject to customary exceptions and
exclusions) confirming that: 
 (A) the Issuer has received from, or there has been published by, the Internal
Revenue Service a ruling; or 
 (B) since the Issue Date there has been a change in the applicable federal income
tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been
the case if such Legal Defeasance had not occurred; 
 (3) in the case of an election under Section 8.03
hereof, the Issuer must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee (subject to customary exceptions and exclusions) confirming that the Holders of the outstanding Notes will not recognize income, gain or loss
for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other
than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing); 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the
Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound; 

  
 -115-








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

 (7) the Issuer must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each
stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05
Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 (a) Subject to
Section 8.06 hereof, all money and non–callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the
“Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either
directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such
money need not be segregated from other funds except to the extent required by law. 
 (b) The Issuer will pay and indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against the cash or non–callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any
such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
 (c) Notwithstanding
anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuer from time to time upon the written request of the Issuer any money or non–callable Government Securities held by it as provided in Section 8.04
hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under clause (1) of Section 8.04
hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to the Issuer. 
 Any money deposited with the
Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium or interest on, any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall
be paid to the Issuer on its written request or (if then held by the Issuer) will be discharged from such trust; and the Holders will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such


  
 -116-








 
repayment, shall, at the expense of the Issuer, cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and
that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. 

Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non–callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be
revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the
case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Issuer will be subrogated to the rights of the Holders
of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 9 

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 9.01 Without Consent of Holders. 
 (a) Notwithstanding Section 9.02 of this Indenture, the Issuer and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees or any Security Document without the consent

(b) Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amendment
or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the Issuer and the Guarantors in the execution of any amendment or supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amendment or supplemental indenture that affects its own
rights, duties or immunities under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders. 

(a) Except as provided in this Section 9.02, the Issuer, the Guarantors and the Trustee and, if applicable, the Collateral Agent, may
amend or supplement this Indenture (including, without limitation, Sections 4.08 and 4.12 hereof) and the Notes or the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes
voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default
(other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this
Indenture, any Security Document or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including, without limitation,
consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

 (b) Upon the written request of the Issuer accompanied by a resolution of its Boards of Directors authorizing the execution
of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the 

  
 -118-








 
Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the Issuer and the Guarantors in the execution of such
amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be
obligated to, enter into such amended or supplemental Indenture. 
 (c) It is not be necessary for the consent of the Holders
under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof. 

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer will mail to the Holders affected
thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.
Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Issuer or any Guarantor with any provision
of this Indenture, the Intercreditor Agreement, the other the Security Documents or the Notes or the Note Guarantees. However, without the consent of each Holder affected thereby, an amendment, supplement or waiver under this Section 9.02 may
not (with respect to any Notes held by a non–consenting Holder): 
 (1) reduce the principal amount of Notes
whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or extend the
fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (for the avoidance of doubt, repurchases of the Notes by the Issuer pursuant to Sections 4.08 and 4.12 hereof are not redemptions of the Notes);

 (3) reduce the rate of or extend the time for payment of interest, including default interest, or premium on
any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or
interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

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

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or impair the rights of
Holders to receive payments of principal of, or interest or premium, if any, on, the Notes; 
 (7) waive a
redemption payment with respect to any Note (for the avoidance of doubt, any payment required by Sections 4.08 or 4.12 hereof is not a redemption payment); 

  
 -119-








 (8) release any Guarantor that is a Significant Subsidiary of the Issuer
from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; 
 (9) make any change in the preceding amendment and waiver provisions; or 
 (10) make any change in the provisions in the Intercreditor Agreement or this Indenture dealing with the application of proceeds of Collateral that would adversely affect the Holders. 

(e) In addition, any amendment to, or waiver of, the provisions of this Indenture, any Security Document or any other indenture governing
Permitted Additional Pari Passu Obligations that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Notes or otherwise modifies the Intercreditor Agreement or other Security Documents in any manner
adverse in any material respect to the Holders will require the consent of the holders of at least 66- 2/3% in aggregate principal amount of the Notes and any Permitted Additional Pari Passu Obligations then outstanding. 

Section 9.03 Intentionally Omitted. 

Section 9.04 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder or portion of a Note that evidences the same debt
as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date
the amendment, supplement or waiver becomes effective. After an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder. 
 Section 9.05 Notation on or Exchange of Notes. 
 The Trustee may place
an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect
the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the
validity and effect of such amendment, supplement or waiver. 
 Section 9.06 Trustee to Sign Amendments, etc. 

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Issuer’s Board of Directors approves it. In executing any amended or supplemental indenture,
the Trustee will be provided with and (subject to Section 7.01 hereof) will be fully protected in conclusively relying upon, in addition to the documents required by Section 14.04 hereof, an Officer’s Certificate and an Opinion of
Counsel stating that the 

  
 -120-








 
execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such amended or supplemental indenture is the legal, valid and binding obligation of the
Issuer or Guarantor, as applicable, enforceable against the Issuer or the Guarantor, as applicable, in accordance with its terms. 
 ARTICLE 10 
 NOTE GUARANTEES 

Section 10.01 Guarantee. 
 (a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally Guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and
the Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: 

(1) the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at
maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee or the Collateral Agent hereunder or
thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will
be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each
Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection. 
 (b) The Guarantors hereby agree that
their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of either Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and
covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 (c) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting


  
 -121-








 
in relation to either the Issuer or the Guarantors, any amount paid by either to the Trustee or the Collateral Agent or such Holder, this Note Guarantee, to the extent theretofore discharged,
will be reinstated in full force and effect. 
 (d) Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders, the
Collateral Agent and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and
payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non–paying Guarantor so long as the exercise of such right does not impair
the rights of the Holders under the Note Guarantee. 
 Section 10.02 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state or provincial law in any
jurisdiction to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Collateral Agent, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to
the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive
contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent
transfer or conveyance. 
 Section 10.03 Intentionally Omitted. 
 Section 10.04 Guarantors May Consolidate, etc., on Certain Terms. 

(a) Except as otherwise provided in this Section 10.04, a Guarantor may not sell or otherwise dispose of all or substantially all of
its assets to, or consolidate with or merge or amalgamate with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuer or another Guarantor, unless: 

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

(2) either: 
 (a) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all


  
 -122-








 
the obligations of that Guarantor under this Indenture, its Note Guarantee, the Intercreditor Agreement and the other Security Documents, pursuant to, in the case of this Indenture and the
relevant agreements, a supplemental indenture in form and substance satisfactory to the Trustee; or 
 (b) the
Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture. 
 In
case of any such consolidation, merger, amalgamation, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee
and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the
Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such
Note Guarantees had been issued at the date of the execution hereof. 
 (b) Except as set forth in Articles 4 and 5 hereof, and
notwithstanding clauses 2(a) and 2(b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation, merger or amalgamation of a Guarantor with or into the Issuer or another Guarantor, or will prevent any
sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor. 

Section 10.05 Releases. 
 (a) The Note Guarantee of a Guarantor will be automatically released and discharged: 
 (1) in connection with any sale, disposition or transfer of all or substantially all of the assets of that Guarantor (including by way of merger, amalgamation, or consolidation) to a Person that is not
(either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary of the Issuer, if the sale, disposition or transfer does not violate Section 4.08 hereof; 

(2) in connection with any sale, disposition or transfer of all of the Capital Stock of that Guarantor to a Person that is
not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary of the Issuer, if the sale, disposition or transfer does not violate Section 4.08 hereof; 

(3) if the Issuer designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance
with the applicable provisions of this Indenture; 
 (4) upon Legal Defeasance in accordance with Article 8
hereof or satisfaction and discharge of this Indenture in accordance with Article 11 and Article 8 hereof; or 

  
 -123-








 (5) upon the release of such Guarantors’ Guarantee under the Credit

 (b) Any Guarantor not released from
its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture

(a) This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 

(1) either: 
 (a) all Notes that have been authenticated and, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held
in trust by the Issuer and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or 
 (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within
one year or may be called for redemption within one year and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars,
non–callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness (including all principal and interest) on
the Notes not delivered to the Trustee for cancellation; 
 (2) the Issuer or any Guarantor has paid or caused to
be paid all sums payable by it under this Indenture; and 
 (3) the Issuer has delivered irrevocable written
instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 (b) In addition, an Officer’s Certificate and an Opinion of Counsel have been delivered to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

 (c) Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant

Sections 11.02 and 8.06 hereof will survive such satisfaction and discharge. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07

Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as
its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from
other funds except to the extent required by law. 
 (b) If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the
Issuer’s and any Guarantor’s obligations under this Indenture and the Notes and Note Guarantees, as applicable, shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that
if the Issuer has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from
the money or Government Securities held by the Trustee or Paying Agent.

Security Documents and all rights and obligations of the Trustee and Collateral Agent hereunder are expressly subject to the Intercreditor Agreement and (ii) the exercise of any right or remedy by the Trustee hereunder is subject to the
limitation and provisions of the Intercreditor Agreement. In the event of any conflict or inconsistency between the terms of the Intercreditor Agreement and the terms of this Indenture, the terms of the Intercreditor Agreement, shall govern.

 Section 12.02 Intentionally Omitted. 
 Section 12.03 Release of Collateral. 
 The Liens securing the Notes
and the Guarantees will, automatically and without the need for any further action by any Person be released: 
 (a) in whole or
in part, as applicable, as to all or any the portion of property subject to such Liens which has been taken by eminent domain, condemnation or other similar circumstances in accordance with the terms of Section 4.08;

securing the Notes, with the consent of the Holders of at least 66 2/3% of the aggregate principal amount of Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, Notes) and
any Permitted Additional Pari Passu Obligations outstanding; 
 (f) as to any MTBE Assets (including the Capital Stock of any
Permitted MTBE Joint Venture) subject to a security interest granted under a mortgage, security agreement or other security interest in favor of the Collateral Agent, upon the earlier of (a) the Issuer’s written request and (b) the
disposition of such MTBE Asset; 
 (g) as to (A) any Capital Stock of any MTBE Subsidiary that is a Restricted Subsidiary

Mortgaged Property; and 
 (h) in part or in whole, in accordance with the applicable provisions of the Intercreditor Agreement

not be included in the Collateral with respect to the Notes (or any Permitted Additional Pari Passu Obligations outstanding) so affected and shall not be subject to the Liens securing such Notes and any Permitted Additional Pari Passu Obligations.
In determining whether any such release is permitted, the Collateral Agent may rely upon a certificate of the Issuer that the Collateral is permitted to be released under this Indenture.

the Security Agreement and the other Security Documents in contravention thereof.

exchange or otherwise dispose of any portion of the Collateral that, under the terms of this Indenture may be sold, exchanged or otherwise disposed of by the Issuer or any Guarantor, and the Issuer or such Guarantor requests the Trustee in writing
to furnish a written disclaimer, release or quitclaim of any interest in such property under this Indenture, the applicable Guarantee and the Security Documents, upon receipt of an Officer’s Certificate and Opinion of Counsel to the effect that
such release complies with Section 12.03

 Subject to the provisions of the Security Documents, the Issuer and the Guarantors shall have the right to
remain in possession and retain exclusive control of and to exercise all rights with respect to the Collateral (other than Trust Monies held by the Collateral Agent, other monies or U.S. Government Obligations deposited pursuant to Article 8 or
Article 11, and other than as set forth in the Security Documents and this Indenture), to freely operate, manage, develop, lease, use, consume and enjoy the Collateral (other than Trust Monies held by the Collateral Agent, other monies and U.S.
Government Obligations deposited pursuant to Article 8 or Article 11 and other than as set forth in the Security Documents and this Indenture), to alter or repair any Collateral so long as such alterations and repairs do not materially impair the
Lien of the Security Documents thereon, and to collect, receive, use, invest and dispose of the reversions, remainders, interest, rents, lease payments, issues, profits, revenues, proceeds and other income thereof and to effect transactions
permitted under Sections 4.08 and 5.01.

Section 12.07 Collateral Agent. 
 (a) The Trustee and each of the Holders by acceptance of the Notes hereby acknowledge the Issuer’s appointment of the Collateral Agent as the Trustee’s collateral agent under this Indenture and
the Security Documents and the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture and the Security Documents and to
exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto. The Collateral Agent agrees to
act as such on the express conditions contained in this Section 12.07. The provisions of this Section 12.07 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor the Issuer or any of the
Guarantors shall have any rights as a third party beneficiary of any of the provisions contained herein other than as expressly provided in Section 12.03. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and
the Security Documents, the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein or in the Security Documents, nor shall the Collateral Agent have or be deemed to have any fiduciary relationship
with the Trustee, any Holder or the Issuer or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the
Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent shall not be construed to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any 

  
 -128-








 
applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.
Except as expressly otherwise provided in this Indenture and the Security Documents, the Collateral Agent shall exercise or refraining from exercising any discretionary rights or taking or refraining from taking any actions which the Collateral
Agent is expressly entitled to take or assert under this Indenture and the Security Documents, including the exercise of remedies pursuant to Article 6, and any action so taken or not taken shall be deemed consented to by the Trustee and the
Holders. 
 (b) The Collateral Agent may execute any of its duties under this Indenture and the Security Documents by or through
agents, employees or attorneys–in–fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agent, employee or
attorney–in–fact that it selects as long as such selection was made with due care. 
 (c) None of the Collateral Agent
or any of its agents or employees shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful
misconduct) or under or in connection with any Security Document or the transactions contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to the Trustee or any Holder for any
recital, statement, representation, warranty, covenant or agreement made by the Issuer or any Guarantor, contained in this Indenture or any indenture, or in any certificate, report, statement or other document referred to or provided for in, or
received by the Collateral Agent under or in connection with, this Indenture or any other indenture, the Security Documents, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture or any other indenture or the
Security Documents, or for any failure of the Issuer or any Guarantor or any other party to this Indenture or the Security Documents to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its agents or employees
shall be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture or any other indenture or the Security Documents or to
inspect the properties, books or records of the Issuer or any Guarantor. 
 (d) The Collateral Agent shall not be deemed to have
actual knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee or the Issuer referring to this Indenture, describing such Default or Event of Default
and stating that such notice is a “notice of default.” The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 (subject to this
Section 12.07); provided, however, that unless and until the Collateral Agent has received any such request, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable. 
 (e) A resignation or removal of the Collateral Agent and appointment
of a successor Collateral Agent shall become effective only upon the successor Collateral Agent’s acceptance of appointment as provided in this Section 12.07(e). The Collateral Agent may


  
 -129-








 
resign in writing at any time by so notifying the Issuer, the Trustee and each trustee, agent or representative of holders of Permitted Additional Pari Passu Obligations at least 30 days prior to
the proposed date of resignation. The Issuer may remove the Collateral Agent if: (i) the Collateral Agent (x) fails to meet the requirements for being a Trustee under Section 7.10 (prior to the discharge or defeasance of this
Indenture) and (y) following the discharge or defeasance of this Indenture, fails to meet the requirements for being the trustee, agent or representative of holders of any extant Permitted Additional Pari Passu Obligations; (ii) the
Collateral Agent is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Collateral Agent under any Bankruptcy Law; (iii) a custodian or public officer takes charge of the Collateral Agent or its property;
or (iv) the Collateral Agent becomes incapable of acting. If the Collateral Agent resigns or is removed or if a vacancy exists in the office of Collateral Agent for any reason, the Issuer shall promptly appoint a successor Collateral Agent
which complies with the eligibility requirements contained in this Indenture and each indenture, credit agreement or other agreements which any Permitted Additional Pari Passu Obligations (other than Additional Notes) are incurred. If a successor
Collateral Agent does not take office within ten days after the retiring Collateral Agent resigns or is removed, the retiring or removed Collateral Agent, the Issuer or the holders of at least 10% in principal amount of the then outstanding
principal amount of (x) the Notes (other than any Additional Notes except to the extent constituting Permitted Additional Pari Passu Obligations) and (y) Permitted Additional Pari Passu Obligations (to the extent the trustee, agent or
representative of holders of such Permitted Additional Pari Passu Obligations executed a joinder to the Security Agreement) may petition any court of competent jurisdiction, at the expense of the Issuer for the appointment of a successor Collateral
Agent. A successor Collateral Agent shall deliver a written acceptance of its appointment to the retiring Collateral Agent and to the Issuer. Thereupon, the resignation or removal of the retiring Collateral Agent shall become effective, and the
successor Collateral Agent shall have all the rights, powers and the duties of the Collateral Agent under this Indenture and the Security Documents. The successor Collateral Agent shall mail a notice of its succession to the Trustee and each
trustee, agent or representative of holders of Permitted Additional Pari Passu Obligations. The retiring Collateral Agent shall promptly transfer all property held by it as Collateral Agent to the successor Collateral Agent, provided that all sums
owing to the Collateral Agent hereunder have been paid. Notwithstanding replacement of the Collateral Agent pursuant to this Section 12.07(e), the Issuer’s obligations under this Section 12.07 and Section 12.12 shall continue for
the benefit of the retiring Collateral Agent. 
 (f) Except as otherwise explicitly provided herein or in the Security
Documents, neither the Collateral Agent nor any of its officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to
sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own willful misconduct, gross
negligence or bad faith. 
 (g) The Trustee is authorized and directed in writing by the Holders and the Holders by acquiring
the Notes are deemed to have authorized the Trustee, as applicable, to (i)

  
 -130-








 
enter into the Security Documents, (ii) bind the Holders on the terms as set forth in the Security Documents and (iii) perform and observe its obligations under the Security Documents.
The Collateral Agent is authorize and directed by the Trustee and the Holders and the Holders by acquiring the Notes and deemed to have authorized the Collateral Agent to (i) enter into the Security Documents, (ii) bind the Trustee and the
Holders on the terms as set forth in the Security Documents and (iii) perform and observe its obligations under the Security Documents. 
 (h) Neither the Collateral Agent nor the Trustee shall have any obligation whatsoever to assure that the Collateral exists or is owned by the Issuer and the Guarantors or is cared for, protected or
insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of
the Grantor’s property constituting collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity,
marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to
the Collateral Agent pursuant to this Indenture or any Security Document, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent may act in any manner it may deem
appropriate, in its sole discretion given the Collateral Agent’s own interest in the Collateral, and that neither the Collateral Agent nor the Trustee shall have any other duty or liability whatsoever as to any of the foregoing. 

(i) The Collateral Agent (i) shall not be liable for any action it takes or omits to take in good faith which it reasonably believes
to be authorized or within its rights or powers, or for any error of judgment made in good faith by an authorized officer, unless it is proved that the Collateral Agent was negligent in ascertaining the pertinent facts, (ii) shall not be liable
for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuer (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent required by law), and
(iii) may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it in
good faith and in accordance with the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act. In no event shall the Collateral Agent be responsible or liable
for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Collateral Agent has been advised of the likelihood of such loss or damage and
regardless of the form of action. 
 (j) Notwithstanding anything to the contrary in this Indenture (including this Article 12),
in the event of a foreclosure on the Mortgaged Property and/or the exercise of its remedies under the Security Documents, the Trustee and Collateral Agent agree that they shall not take any action that results in the disturbance, extinguishment or
termination of any Permitted Liens granted pursuant to clause 14(B) of the definition thereof. Upon the request of the Issuer, the Collateral Agent shall enter into (x) in the case of any such Permitted Lien that is a lease, a subordination
non–disturbance and attornment agreement and (y) in the case of 

  
 -131-








 
any such other Permitted Lien, a nondisturbance agreement, consent or such other agreement which, in each case, confirms that in the event of a foreclosure on the Mortgaged Property and/or
exercise of remedies under the Security Documents, the Collateral Agent (and its successors and assigns) will not disturb, extinguish or terminate any such Permitted Liens (or the rights thereunder). Any request by the Issuer pursuant to the
preceding sentence shall be evidenced by a certificate from an officer of the Issuer which certificate shall certify that (1) the Permitted Liens in question do not materially adversely affect or impair (A) the business operations of the
Issuer and its Restricted Subsidiaries as a whole or (B) the validity or priority of the Lien of the Mortgages on the balance of the Mortgaged Property and (2) the applicable non–disturbance agreement, consent or other agreement
provides that the Permitted Liens in question are subordinate to the Lien in favor of the Collateral Agent on the Mortgaged Property. 
 (k) The Trustee and the Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in their possession if the Collateral is accorded treatment substantially equal
to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any Collateral, by reason of the act or omission of any carrier, forwarding agent or other agent or bailee selected by the
Trustee or the Collateral Agent in good faith. Neither the Trustee nor the Collateral Agent shall be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times
or otherwise perfecting or maintaining the perfection of any security interest in the Collateral.

satisfied.

deemed the equivalent of any similar instrument of the Issuer or any Guarantor, as applicable, or of any officer or officers thereof required by the provisions of this Article 12.

Equivalents pursuant to a written request by the Issuer in the form of an Officer’s Certificate, which shall specify the Cash Equivalents in which such Trust Monies shall be invested and shall certify that such investments constitute Cash
Equivalents; and the Collateral Agent shall sell any such Cash Equivalent only upon receipt of such a written request by the Issuer specifying the particular Cash Equivalent to be sold. So long as no Event of Default occurs and is continuing, any

Equivalents shall be held by the Collateral Agent as a part of the Collateral, subject to the same provisions hereof as the cash used by it to purchase such Cash Equivalents.

 [Back of 144A Global Note] 

8.75% Senior Secured Notes due 2020 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. TPC Group Inc., a Delaware corporation (the “Issuer”), promises to pay interest on the principal amount of this Note at 8.75% per annum from December 20,
2012 until maturity. The Issuer will pay interest semi–annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment
Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 20, 2012 until the principal hereof is due. The first Interest Payment Date shall be
June 15, 2013. The Issuer will pay interest on overdue principal at the rate borne by the Notes, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. Interest will be computed on the basis of a
360–day year of twelve 30–day months. 
 (2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders at the close of business on the June 1 or December 1 immediately preceding the Interest Payment Date (whether or not a Business Day), even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Payments in respect of Notes represented by Global Notes (including principal, premium,
if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depositary. The Issuer will make all payments in respect of a Definitive Note (including
principal, premium, if any, and interest), at the office of each Paying Agent, except that, at the option of the Issuer, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Notes may also be made in the case of a Holder of at least $1,000,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if
such Holder elects payment by wire transfer by giving written notice to the Trustee or a Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the
Trustee may accept in its discretion). Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3) PAYING AGENT AND REGISTRAR. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of the Issuer’s Subsidiaries may act in any such capacity. 

(4) INDENTURE. The Issuer issued the Notes under an Indenture dated as of December 20, 2012 (the
“Indenture”) among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture.
The Notes are subject to all the terms and provisions of the Indenture, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. 

  
 A1-3








 The Notes are senior secured obligations of the Issuer. This Note is one of the Notes
referred to in the Indenture. The Notes include the Initial Notes and any Additional Notes. The Initial Notes and any Additional Notes are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the
ability of the Issuer and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, incur Indebtedness, enter into consensual restrictions upon the payment of
certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of capital stock of the Issuer and such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or incur Liens and make
asset sales. The Indenture also imposes limitations on the ability of the Issuer and each Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of its property. 

To guarantee the due and punctual payment of the principal and interest on the Notes and all other amounts payable by the Issuer under
the Indenture, the Notes and the Security Documents when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have, jointly and severally,
unconditionally guaranteed the Obligations of the Issuer under the Notes on a senior secured basis pursuant to the terms of the Indenture. 
 The Notes shall be secured by Liens and security interests, subject to Permitted Liens, in the Collateral on the terms and conditions set forth in the Indenture, the Intercreditor Agreement and the other
Security Documents. The Collateral Agent holds the Collateral in trust for the benefit of the Holders of the Note Obligations and the Trustee and the Holders, in each case pursuant to the Security Documents. The Collateral will also secure
obligations under Permitted Additional Pari Passu Obligations and Indebtedness and other Obligations permitted under the Indenture to be secured. 
 Each Holder by accepting this Note consents and agrees to the terms of the Intercreditor Agreement and the other Security Documents as the same may be in effect or may be amended from time to time in
accordance with their terms and the Indenture authorizes and directs the Collateral Agent and the Trustee, as applicable, to enter into the Intercreditor Agreement and the other Security Documents and to perform its obligations and exercise its
rights thereunder in accordance therewith. 
 (5) OPTIONAL REDEMPTION. 

(a) At any time prior to December 15, 2015, the Issuer may on any one or more occasions redeem up to 35% of the aggregate principal
amount of Notes issued under the Indenture at a redemption price of 108.750% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the redemption date (subject to the right of Holders on the relevant record date to
receive interest due on the relevant interest payment date), with the net cash proceeds of one or more Equity Offerings; provided that: 
 (1) at least 50% of the aggregate principal amount of Notes issued under the Indenture (excluding Notes held by the Issuer and its Subsidiaries, including the Issuer) remains outstanding immediately after
the occurrence of such redemption (unless all of such Notes are redeemed); and 

  
 A1-4








 (2) the redemption occurs within 180 days of the date of the closing of such
Equity Offering. 
 (b) On or after December 15, 2016, the Issuer may redeem all or a part of the Notes at the redemption
prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but not including, the applicable redemption date, if redeemed during the 12–month period beginning on
December 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date: 

 

					
	 Year
	  	Percentage	 
	 2016
	  	 	104.375	% 
	 2017
	  	 	102.188	% 
	 2018 and thereafter
	  	 	100.000	% 

 Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the
Notes or portions thereof called for redemption on the applicable redemption date. 
 (c) During any 12–month period
commencing on the date that is one year after the Issue Date until December 15, 2016, the Issuer will be entitled at its option to redeem up to 10% of the aggregate principal amount of the Notes issued under the Indenture at a redemption price
equal to 103.000% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, on the Notes to be redeemed to, but not including, the redemption date (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date). 
 (d) The Notes will be subject to redemption as a whole, but not
in part, at the option of the Issuer at any time, at 100% of the principal amount, plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the redemption date (subject to the right of Holders on the relevant record date
to receive interest due on the relevant Interest Payment Date). 
 (e) At any time prior to December 15, 2016, the Issuer
may also redeem all or a part of the Notes, at a redemption price equal to 100% of the aggregate principal amount hereof plus the Applicable Premium as of, and accrued and unpaid interest to, but not including, the date of redemption, subject to the
rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. 
 (6) MANDATORY

 The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection
with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess of $2,000. 

(8) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a Change of Control, the Issuer will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of
$1,000 in excess of $2,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to, but not including, the date of
purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control, the Issuer will mail a notice to each Holder setting forth the
procedures governing the Change of Control Offer as required by the Indenture. 
 (b) If the Issuer or a Restricted Subsidiary
of the Issuer consummates any Asset Sales, within ten Business Days of each date on which the aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuer will commence an offer to all Holders and (x) in the case of Net Proceeds from
Notes Priority Collateral, to the holders of any other Permitted Additional Pari Passu Obligations containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets

 [Back of Regulation S Global Note] 

8.75% Senior Secured Note due 2020 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. TPC Group Inc., a Delaware corporation (the “Issuer”), promises to pay interest on the principal amount of this Note at 8.75% per annum from December 20,
2012 until maturity. The Issuer will pay interest semi–annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment
Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 20, 2012 until the principal hereof is due. The first Interest Payment Date shall be
June 15, 2013. The Issuer will pay interest on overdue principal at the rate borne by the Notes, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. Interest will be computed on the basis of a
360–day year of twelve 30–day months. 
 (2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders at the close of business on the June 1 or December 1 immediately preceding the Interest Payment Date (whether or not a Business Day), even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Payments in respect of Notes represented by Global Notes (including principal, premium,
if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depositary. The Issuer will make all payments in respect of a Definitive Note (including
principal, premium, if any, and interest), at the office of each Paying Agent, except that, at the option of the Issuer, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided, however, that
payments on the Notes may also be made in the case of a Holder of at least $1,000,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects
payment by wire transfer by giving written notice to the Trustee or a Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in
its discretion). Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3) PAYING AGENT AND REGISTRAR. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of the Issuer’s Subsidiaries may act in any such capacity. 

(4) INDENTURE. The Issuer issued the Notes under an Indenture dated as of December 20, 2012 (the
“Indenture”) among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture.
The Notes are subject to all the terms and provisions of the Indenture, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. 

  
 A2-3








 The Notes are senior secured obligations of the Issuer. This Note is one of the Notes
referred to in the Indenture. The Notes include the Initial Notes and any Additional Notes. The Initial Notes and any Additional Notes are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the
ability of the Issuer and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, incur Indebtedness, enter into consensual restrictions upon the payment of
certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of capital stock of the Issuer and such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or incur Liens and make
asset sales. The Indenture also imposes limitations on the ability of the Issuer and each Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of its property. 

To guarantee the due and punctual payment of the principal and interest on the Notes and all other amounts payable by the Issuer under
the Indenture, the Notes and the Security Documents when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have, jointly and severally,
unconditionally guaranteed the Obligations of the Issuer under the Notes on a senior secured basis pursuant to the terms of the Indenture. 
 The Notes shall be secured by Liens and security interests, subject to Permitted Liens, in the Collateral on the terms and conditions set forth in the Indenture, the Intercreditor Agreement and the other
Security Documents. The Collateral Agent holds the Collateral in trust for the benefit of the Holders of the Note Obligations and the Trustee and the Holders, in each case pursuant to the Security Documents. The Collateral will also secure
obligations under Permitted Additional Pari Passu Obligations and Indebtedness and other Obligations permitted under the Indenture to be secured. 
 Each Holder by accepting this Note consents and agrees to the terms of the Intercreditor Agreement and the other Security Documents as the same may be in effect or may be amended from time to time in
accordance with their terms and the Indenture authorizes and directs the Collateral Agent and the Trustee, as applicable, to enter into the Intercreditor Agreement and the other Security Documents and to perform its obligations and exercise its
rights thereunder in accordance therewith. 
 (5) OPTIONAL REDEMPTION. 

(a) At any time prior to December 15, 2015, the Issuer may on any one or more occasions redeem up to 35% of the aggregate principal
amount of Notes issued under the Indenture at a redemption price of 108.750% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the redemption date (subject to the right of Holders on the relevant record date to
receive interest due on the relevant interest payment date), with the net cash proceeds of one or more Equity Offerings; provided that: 
 (1) at least 50% of the aggregate principal amount of Notes issued under the Indenture (excluding Notes held by the Issuer and its Subsidiaries, including the Issuer) remains outstanding immediately after
the occurrence of such redemption (unless all of such Notes are redeemed); and 

  
 A2-4








 (2) the redemption occurs within 180 days of the date of the closing of such
Equity Offering. 
 (b) On or after December 15, 2016, the Issuer may redeem all or a part of the Notes at the redemption
prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but not including, the applicable redemption date, if redeemed during the 12–month period beginning on
December 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date: 

 

					
	 Year
	  	Percentage	 
	 2016
	  	 	104.375	% 
	 2017
	  	 	102.188	% 
	 2018 and thereafter
	  	 	100.000	% 

 Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the
Notes or portions thereof called for redemption on the applicable redemption date. 
 (c) During any 12–month period
commencing on the date that is one year after the Issue Date until December 15, 2016, the Issuer will be entitled at its option to redeem up to 10% of the aggregate principal amount of the Notes issued under the Indenture at a redemption price
equal to 103.000% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, on the Notes to be redeemed to, but not including, the redemption date (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date). 
 (d) The Notes will be subject to redemption as a whole, but not
in part, at the option of the Issuer at any time, at 100% of the principal amount, plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the redemption date (subject to the right of Holders on the relevant record date
to receive interest due on the relevant Interest Payment Date). 
 (e) At any time prior to December 15, 2016, the Issuer
may also redeem all or a part of the Notes, at a redemption price equal to 100% of the aggregate principal amount hereof plus the Applicable Premium as of, and accrued and unpaid interest to, but not including, the date of redemption, subject to the
rights of Holders on the relevant record date to receive interest due on the relevant interest payment date.

not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection
with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess of $2,000. 

(8) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a Change of Control, the Issuer will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of
$1,000 in excess of $2,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to, but not including, the date of
purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control, the Issuer will mail a notice to each Holder setting forth the
procedures governing the Change of Control Offer as required by the Indenture. 
 (b) If the Issuer or a Restricted Subsidiary
of the Issuer consummates any Asset Sales, within ten Business Days of each date on which the aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuer will commence an offer to all Holders and (x) in the case of Net Proceeds from
Notes Priority Collateral, to the holders of any other Permitted Additional Pari Passu Obligations containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets
or (y) in the case of any other Net Proceeds, to all holders of other Pari Passu Payment Lien Obligations containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales
of assets (an “Asset Sale Offer”) pursuant to Section 4.08 of the Indenture to purchase the maximum principal amount of Notes and Permitted Additional Pari Passu Obligations or other Pari Passu Payment Lien Obligations, as
appropriate, that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest thereon to, but excluding, the date of purchase, in accordance with
the procedures set forth in the Indenture. To the extent that any Excess Proceeds remain after the consummation of an Asset Sale Offer, the Issuer or any Restricted Subsidiary of the Issuer may use those Excess Proceeds for any purpose not otherwise
prohibited by the Indenture. If the aggregate principal amount of Notes and Permitted Additional Pari Passu Obligations or other Pari Passu Payment Lien Obligations, as appropriate, tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis. Holders that are the subject of an offer to purchase will receive an Asset Sale Offer from the Issuer prior to any related purchase date and may elect to have
