effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a

the Company or a Wholly Owned Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each
Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Securities, and shall
notify the Trustee of any default by the Company in making any such payment. If the Company or a Wholly Owned Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the
benefit of the Persons entitled thereto. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. During the continuance of an Event of Default under
this Indenture, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. 
  

 -41- 








 
Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent. Upon complying with this Section 2.05, a Paying Agent shall have no further
liability for the money delivered to the Trustee. 
 SECTION 2.06.    Holder Lists.  The
Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Paying Agent is not the same entity as the Registrar, the Company shall furnish, or cause
the Registrar to furnish, to the Paying Agent, in writing at least five Business Days before each interest payment date and at such other times as the Paying Agent may request in writing, a list in such form and as of such date as the Paying Agent
may reasonably require of the names and addresses of Holders. 
 SECTION 2.07.    Transfer and
Exchange.  The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with the Appendix. When a Security is presented to the
Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Securities are presented to the
Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the
Company shall execute and the Authentication Agent shall authenticate Securities at the Registrar’s request. The Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any
transfer or exchange pursuant to this Section 2.07 (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Section 3.08, 4.06, 4.08 or 9.05). The Company shall not be
required to make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or of any Securities for a period
of 15 days before a selection of Securities to be redeemed. 
 Prior to the due presentation for registration of transfer of
any Security, the Company, the Guarantors, the Trustee, each Paying Agent and the Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal
of and interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, any Guarantor, the Trustee, a Paying Agent or the Registrar shall be affected by notice to the
contrary. 
 Any Holder of a beneficial interest in a Global Security shall, by acceptance of such beneficial interest, agree
that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any Holder of a beneficial interest in such Global
Security, and that ownership of a beneficial interest in such Global Security shall be required to be reflected in a book entry. 
  

 -42- 








 All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture
shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange. 

SECTION 2.08.    Replacement Securities.  If a mutilated Security is surrendered to the Registrar
or if the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall issue and the Authentication Agent shall authenticate a replacement Security if the requirements of Section 8-405
of the Uniform Commercial Code are met, such that the Holder (a) notifies the Company or the Registrar within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a
transfer prior to receiving such notification, (b) makes such request to the Company or the Registrar prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a
“protected purchaser”) and (c) satisfies any other reasonable requirements of the Registrar. If required by the Registrar, Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of
(i) the Registrar or Trustee to protect the Registrar or Trustee or (ii) the Company, to protect the Company, the Trustee, the Paying Agent and the Registrar, from any loss that any of them may suffer if a Security is replaced. The
Company, the Registrar and the Trustee may charge the Holder for their expenses in replacing a Security (including, without limitation, attorneys’ fees and disbursements in replacing such Security). In the event any such Security has become or
is about to become due and payable, the Company in its discretion may direct the Registrar to pay the same without surrender thereof upon the Holder furnishing the Company and the Registrar with indemnity satisfactory to them and complying with such
other reasonable regulations as the Company may prescribe and paying such reasonable expense as the Company and the Registrar may incur in connection therewith. 

Every replacement Security is an additional obligation of the Company. 

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Securities. 
 SECTION
2.09.    Outstanding Securities.  Securities outstanding at any time are all Securities authenticated by the Authentication Agent except for those canceled by it or the Registrar, those delivered to it for
cancellation and those described in this Section 2.09 as not outstanding. Subject to Section 13.06, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 

If a Security is replaced pursuant to Section 2.08 (other than a mutilated Security surrendered for replacement), it ceases to be
outstanding unless the Trustee, Registrar and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser. A mutilated Security ceases to be outstanding upon surrender of such Security and replacement
thereof pursuant to Section 2.08. 
 If the Paying Agent segregates and holds in trust, in accordance with this Indenture,
on a redemption date or maturity date money sufficient to pay all principal and interest payable 
  

 -43- 








 
on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying such money to the Holders on that
date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

SECTION 2.10.    Temporary Securities.  In the event that Definitive Securities are to be issued
under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Company may prepare and the Authentication Agent shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of
Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Authentication Agent shall authenticate Definitive Securities and make them
available for delivery in exchange for temporary Securities upon surrender of such temporary Securities at the office or agency of the Company, without charge to the Holder. Until such exchange, temporary Securities shall be entitled to the same
rights, benefits and privileges as Definitive Securities. 
 SECTION
2.11.    Cancellation.  The Company at any time may deliver Securities to the Registrar for cancellation. Any person other than the Registrar shall forward to the Registrar any Securities surrendered to them for
registration of transfer, exchange or payment. The Registrar and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Securities in accordance with its
customary procedures (subject to the record retention requirements of the Exchange Act) or deliver copies of canceled Securities to the Company pursuant to written direction by an Officer of the Company. The Company may not issue new Securities to
replace Securities it has redeemed, paid or delivered to the Registrar for cancellation. The Authentication Agent shall not authenticate Securities in place of canceled Securities other than pursuant to the terms of this Indenture. 

SECTION 2.12.    Defaulted Interest.  If the Company defaults in a payment of interest on the
Securities, the Company shall pay the defaulted interest then borne by the Securities (plus interest on such defaulted interest to the extent lawful), in any lawful manner. The Company may pay the defaulted interest to the Persons who are Holders on
a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and Registrar and shall promptly mail or cause to be mailed to each affected
Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 

SECTION 2.13.    CUSIP Numbers, ISINs, etc.  The Company in issuing the Securities may use CUSIP
numbers, ISINs and “Common Code” numbers (if then generally in use) and, if so, the Registrar shall use CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided,
however, that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Securities or as contained in any notice of a redemption, that reliance may be placed only on the other
identification numbers printed on the Securities and that any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee 

 

 -44- 








 
and Registrar in writing of any change in the CUSIP numbers, ISINs and “Common Code” numbers. 

SECTION 2.14.    Calculation of Specified Percentage of Securities.  With respect to any matter
requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the Securities, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the
principal amount, as of such date of determination, of Securities, the Holders of which have so consented by (b) the aggregate principal amount, as of such date of determination, of the Securities then outstanding, in each case, as determined
in accordance with the preceding sentence, Section 2.09 and Section 13.06 of this Indenture. Any such calculation made pursuant to this Section 2.14 shall be made by the Company and delivered to the Trustee and the Registrar pursuant
to an Officers’ Certificate. 
 ARTICLE 3 

REDEMPTION 

SECTION 3.01.    Redemption.  Subject to the conditions and at the redemption prices set forth in
Paragraph 5 of the form of Securities set forth in Exhibit A and Exhibit B hereto, which are hereby incorporated by reference and made a part of this Indenture, the Securities may be redeemed, in whole, or from time to time in part,
together with accrued and unpaid interest to the redemption date. 
 SECTION 3.02.    Applicability of
Article.  Redemption of Securities at the election of the Company or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article 3. 

SECTION 3.03.    Notices to Trustee.  If the Company elects to redeem Securities pursuant to the
optional redemption provisions of Paragraph 5 of the applicable Security, it shall notify the Trustee and Registrar in writing of (i) the Section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date,
(iii) the principal amount of Securities to be redeemed and (iv) the redemption price. If the redemption is made pursuant to paragraph 5 of the applicable Security, the Company shall give notice to the Trustee and Registrar provided for in
this paragraph at least 40 days but not more than 60 days before the date of such redemption unless a shorter period is acceptable to the Trustee and Registrar. Such notice shall be accompanied by an Officers’ Certificate and Opinion
of Counsel from the Company to the effect that such redemption will comply with the conditions herein. If fewer than all the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and given in
writing to the Trustee and Registrar, which record date shall be not fewer than 15 days after the date of notice to the Trustee and Registrar. Any such notice may be canceled at any time prior to notice of such redemption being sent to any
Holder and shall thereby be void and of no effect. 
  

 -45- 








 SECTION 3.04.    Selection of Securities to Be
Redeemed.  In the case of any partial redemption, selection of the Securities for redemption will be made by the Registrar in compliance with the requirements of the principal national securities exchange, if any, on which such
Securities are listed, or if such Securities are not so listed, by lot or by such other method as the Registrar shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that, to the extent
practicable, the Registrar shall not select Securities for redemption which would result in a Holder of Securities having a principal amount of Securities less than the minimum denomination. The Registrar shall make the selection from outstanding
Securities not previously called for redemption. The Registrar may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Registrar selects shall be in amounts of
$2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Registrar shall notify the Company promptly of the
Securities or portions of Securities to be redeemed. 
 SECTION 3.05.    Notice of Optional
Redemption. 
 (a)       At least 30 days but not more than 60 days before the date
of redemption of Securities pursuant to Paragraph 5 of the applicable Security, the Company shall mail or cause to be mailed by first-class mail a notice of redemption to the registered address of each Holder whose Securities are to be redeemed or
otherwise in accordance with the procedures of the Depository. 
 Any such notice shall identify the Securities to be redeemed
and shall state: 
 (i)        the redemption date; 

(ii)       the redemption price and the amount of accrued and unpaid interest to the
redemption date; 
 (iii)      the name and address of a Paying Agent; 

(iv)      that Securities called for redemption must be surrendered to a Paying Agent to
collect the redemption price, plus accrued and unpaid interest; 

(v)       if fewer than all the outstanding Securities are to be redeemed, the
certificate numbers and principal amounts of the particular Securities to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial redemption;

 (vi)      that, unless the Company defaults in making such redemption payment
or any Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date; 

 

 -46- 








 (vii)      the CUSIP number, ISIN and/or
“Common Code” number, if any, printed on the Securities being redeemed; and 

(viii)     that no representation is made as to the correctness or accuracy of the CUSIP number
or ISIN and/or “Common Code” number, if any, listed in such notice or printed on the Securities. 
 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 Company’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. 
 (b)       At the Company’s request, the Registrar
shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company has delivered to the Trustee and Registrar, at least 45 days (unless a shorter period is acceptable
to the Trustee and Registrar) prior to the redemption date, an Officers’ Certificate requesting that the Registrar give such notice. In such event, the Company shall provide the Registrar in writing with the information required by this
Section 3.05. 
 SECTION 3.06.    Effect of Notice of Redemption.  Once notice of
redemption is mailed in accordance with Section 3.05, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice (except to the extent such redemption is conditional as set
forth in Section 3.05). Upon surrender to any Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest to the redemption date; provided, however, that if the
redemption date is after a regular record date and on or prior to the interest payment date, the accrued interest shall be payable to the Holder of the redeemed Securities registered on the relevant record date. Failure to give notice or any defect
in the notice to any Holder shall not affect the validity of the notice to any other Holder or the validity of the redemption. 

SECTION 3.07.    Deposit of Redemption Price.  Prior to 10:00 a.m., New York City time, on the
redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Wholly Owned Subsidiary is a Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all
Securities or portions thereof to be redeemed on that date other than Securities or portions of Securities called for redemption that have been delivered by the Company to the Registrar for cancellation. On and after the redemption date, interest
shall cease to accrue on Securities or portions thereof called for redemption so long as the Company has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Securities to be redeemed,
unless a Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture. 
 SECTION
3.08.    Securities Redeemed in Part.  Upon surrender of a Security that is redeemed in part, the Company shall execute and the Authentication Agent shall authenticate

  

 -47- 








 
for the Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered. 

ARTICLE 4 

COVENANTS 

SECTION 4.01.    Payment of Securities.  The Company shall promptly pay the principal of and
interest, on the Securities on the dates and in the manner provided in the Securities and in this Indenture. An installment of principal of or interest shall be considered paid on the date due if on such date the Paying Agent holds in accordance
with this Indenture money sufficient to pay all principal and interest then due and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. 

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on
overdue installments of interest at the same rate borne by the Securities to the extent lawful. 
 SECTION
4.02.    Reports and Other Information.  Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and
quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, the Company shall file with the SEC (and provide the Trustee and Holders with copies thereof, without cost to each
Holder, within 15 days after it files them with the SEC), 

(a)        within 90 days after the end of each fiscal year (or such longer
period as may be permitted by the SEC if the Company were then subject to such SEC reporting requirements as a required filer, voluntary filer or otherwise), annual reports on Form 10-K (or any successor or comparable form) containing the
information required to be contained therein (or required in such successor or comparable form), 

(b)        within 45 days after the end of each of the first three fiscal
quarters of each fiscal year (or such longer period as may be permitted by the SEC if the Company were then subject to such SEC reporting requirements as a required filer, voluntary filer or otherwise), quarterly reports on Form 10-Q (or any
successor or comparable form), 
 (c)        promptly from time to time
after the occurrence of an event required to be therein reported (and in any event within the time period specified for filing current reports on Form 8-K by the SEC), such other reports on Form 8-K (or any successor or comparable form), and

 (d)        any other information, documents and other reports which
the Company would be required to file with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act; 
  

 -48- 








 provided, however, that the Company shall not be so obligated to file such reports with the
SEC if the SEC does not permit such filing, in which event the Company shall put such information on its website, in addition to providing such information to the Trustee and the Holders, in each case within 15 days after the time the Company
would be required to file such information with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act. For avoidance of doubt, the obligations of the Company under this Section 4.02 shall commence with respect to the
Company’s first fiscal quarter that ends after the Issue Date. 
 In addition, to the extent not satisfied by the
foregoing, the Company shall, for so long as any Securities are outstanding, furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under
the Securities Act. 
 Notwithstanding the foregoing, the Company will be deemed to have furnished such reports referred to
above to the Trustee and the Holders if it has filed such reports with the SEC via the EDGAR filing system (or any successor thereto) and such reports are publicly available. 

Notwithstanding the foregoing, the requirement to provide the information and reports referred to in clauses (a) and (b) above
shall be deemed satisfied prior to the commencement of the Registered Exchange Offer or the effectiveness of a Shelf Registration Statement relating to the registration of the Securities under the Securities Act by the filing (within the time
periods specified for such filings in the registration rights agreement) with the SEC of a registration statement, and any amendments thereto, with such financial information that satisfies Regulation S-X under the Securities Act. 

In the event that: 

(i)        the rules and regulations of the SEC permit the Company and any direct
or indirect parent company of the Company to report at such parent entity’s level on a consolidated basis and such parent entity of the Company is not engaged in any business in any material respect other than incidental to its ownership,
directly or indirectly, of the capital stock of the Company, or 

(ii)        any direct or indirect parent of the Company becomes a Guarantor of
the Securities, 
 such consolidated reporting at such parent entity’s level in a manner consistent with that described in this
Section 4.02 for the Company will satisfy this Section 4.02; provided that such financial information is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to
such direct or indirect parent and any of its Subsidiaries other than the Company and its Subsidiaries, on the one hand, and the information relating to the Company and its Subsidiaries on a stand alone basis, on the other hand. 

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of
such shall not constitute constructive notice 
  

 -49- 








 
of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively (subject to Article 7) on Officers’ Certificates). 
 SECTION
4.03.      Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock. 

(a)      (i) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness) or issue any shares of Disqualified Stock; and (ii) the Company shall not permit any of its Restricted Subsidiaries to issue any shares of Preferred Stock;
provided, however, that the Company and any Restricted Subsidiary may Incur Indebtedness (including Acquired Indebtedness) or issue shares of Disqualified Stock and any Restricted Subsidiary may issue shares of Preferred Stock, in each
case if the Fixed Charge Coverage Ratio of the Company for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is Incurred or
such Disqualified Stock or Preferred Stock is issued would have been at least 2.00 to 1.00 determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been Incurred, or the
Disqualified Stock or Preferred Stock had been issued, as the case may be, and the application of proceeds therefrom had occurred at the beginning of such four-quarter period; provided, further, that Restricted Subsidiaries of the
Company that are not Guarantors may not Incur Indebtedness or issue any shares of Disqualified Stock or Preferred Stock pursuant to this paragraph if, after giving pro forma effect to such Incurrence or issuance (including a pro forma application of
the net proceeds therefrom), more than an aggregate of $10 million of Indebtedness, Disqualified Stock and Preferred Stock of Restricted Subsidiaries that are not Guarantors would be outstanding pursuant to this paragraph. 

(b)      The limitations set forth in Section 4.03(a) shall not apply to (collectively,
“Permitted Debt”): 
 (i)       the Incurrence by the
Company or any of its Restricted Subsidiaries of Indebtedness under one or more Credit Facilities and the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being
deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) up to an aggregate principal amount at any one time outstanding not to exceed the greater of (x) $200 million
and (y) the amount of the Borrowing Base, as of the date of such Incurrence; 

(ii)      the Incurrence by the Company and the Guarantors of Indebtedness represented by
the Original Securities and the Guarantees, as applicable (and any Exchange Securities and guarantees thereof); 

(iii)     Indebtedness existing on the Issue Date (other than Indebtedness described in
clauses (i) and (ii) of this Section 4.03(b)), including any Indebtedness being repaid with the proceeds of the offering as described in the Offering Memorandum; 

 

 -50- 








 (iv)      Indebtedness (including Capitalized
Lease Obligations) Incurred by the Company or any of its Restricted Subsidiaries to finance the purchase, lease, design, construction, installation, repair, replacement or improvement of property (real or personal) or equipment (whether through the
direct purchase of assets or the Capital Stock of any Person owning such assets (but no other material assets)) and related financing costs in an aggregate principal amount which, when aggregated with the principal amount of all other Indebtedness
then outstanding that was Incurred pursuant to this clause (iv), does not exceed $20 million at any one time outstanding; 

(v)       Indebtedness Incurred by the Company or any of its Restricted Subsidiaries
constituting reimbursement obligations with respect to letters of credit and bank guarantees issued in the ordinary course of business, including, without limitation, letters of credit in respect of workers’ compensation claims, health,
disability or other employee benefits (whether current or former) or property, casualty or liability insurance or self-insurance, or other Indebtedness with respect to reimbursement-type obligations regarding workers’ compensation claims;
provided, however, that upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing; 

(vi)      Indebtedness arising from agreements of the Company or a Restricted Subsidiary
providing for indemnification, adjustment of purchase price or similar obligations, in each case, Incurred in connection with the acquisition or the disposition of any business, assets or Subsidiary in accordance with the terms of this Indenture,
other than guarantees of Indebtedness Incurred by any Person acquiring all or any portion of such business, assets or Subsidiary for the purpose of financing such acquisition; 

(vii)     Indebtedness of the Company to a Restricted Subsidiary; provided that any
subsequent issuance or transfer of any Capital Stock or any other event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to the Company or another
Restricted Subsidiary) shall be deemed, in each case, to be an Incurrence of such Indebtedness; 

(viii)     shares of Preferred Stock of a Restricted Subsidiary issued to the Company or another
Restricted Subsidiary; provided that any subsequent issuance or transfer of any Capital Stock or any other event that results in any Restricted Subsidiary that holds such shares of Preferred Stock of another Restricted Subsidiary ceasing to
be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of shares of Preferred Stock; 

(ix)       Indebtedness of a Restricted Subsidiary to the Company or another
Restricted Subsidiary; provided that if a Guarantor incurs such Indebtedness to a Restricted Subsidiary that is not a Guarantor, such Indebtedness must be subordinated in right of payment to the Guarantee of such Guarantor; provided,
further, that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary lending such Indebtedness ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such
Indebtedness (except to the Company or another 
  

 -51- 








 
Restricted Subsidiary) shall be deemed, in each case, to be an Incurrence of such Indebtedness; 

(x)       Hedging Obligations that are Incurred in the ordinary course of business
(and not for speculative purposes): (1) for the purpose of fixing or hedging interest rate risk with respect to any Indebtedness that is permitted by the terms of this Indenture to be outstanding; (2) for the purpose of fixing or hedging
currency exchange rate risk with respect to any currency exchanges; or (3) for the purpose of fixing or hedging commodity price risk with respect to any commodity purchases; 

(xi)      obligations (including reimbursement obligations with respect to letters of
credit and bank guarantees) in respect of performance, bid, appeal and surety bonds and completion guarantees provided by the Company or any Restricted Subsidiary in the ordinary course of business; 

(xii)      (A) any guarantee by the Company or a Restricted Subsidiary of Indebtedness or
other obligations of the Company or any of its Restricted Subsidiaries so long as the Incurrence of such Indebtedness or other obligations by the Company or such Restricted Subsidiary is permitted under the terms of this Indenture; provided
that if such Indebtedness is by its express terms subordinated in right of payment to the Securities or the Guarantee of such Restricted Subsidiary, as applicable, any such guarantee of such Guarantor with respect to such Indebtedness shall be
subordinated in right of payment to the Securities or such Guarantor’s Guarantee with respect to the Securities substantially to the same extent as such Indebtedness is subordinated to the Securities or the Guarantee of such Restricted
Subsidiary, as applicable and (B) any “bad boy,” or springing recourse, guarantee by the Company or any Restricted Subsidiary that is the parent company 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 Company and its Restricted Subsidiaries (other than any MTBE Subsidiary); 

(xiii)      the Incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness or Disqualified Stock or the issuance by any Restricted Subsidiary of any Preferred Stock which serves to refinance, refund, renew, replace, defease, discharge or otherwise retire for value, in whole or in part, any Indebtedness,
Disqualified Stock or Preferred Stock Incurred as permitted under Section 4.03(a) and clauses (ii), (iii), (iv) and (xiii) of this Section 4.03(b) or any Indebtedness, Disqualified Stock or Preferred Stock Incurred to so
refinance, refund, renew, replace, defease, discharge or otherwise retire for value, such Indebtedness, Disqualified Stock or Preferred Stock, including any Indebtedness, Disqualified Stock or Preferred Stock Incurred to pay premiums, fees and
expenses in connection therewith (subject to the following proviso, “Refinancing Indebtedness”) prior to its respective maturity; provided, however, that: 

 

 -52- 








 (1)      such Refinancing Indebtedness has a
Weighted Average Life to Maturity at the time such Refinancing Indebtedness is Incurred which is not less than the remaining Weighted Average Life to Maturity of the Indebtedness being refunded, refinanced, renewed, replaced, defeased, discharged or
retired; 
 (2)      such Refinancing Indebtedness has a Stated Maturity which is
no earlier than the Stated Maturity of the Indebtedness being refinanced, refunded, renewed, replaced, defeased, discharged or retired; 

(3)      to the extent such Refinancing Indebtedness refinances, refunds, renews,
replaces, defeases, discharges, or retires (x) Indebtedness junior to the Securities or the Guarantee of such Restricted Subsidiary, as applicable, such Refinancing Indebtedness is junior to the Securities or the Guarantee of such Restricted
Subsidiary, as applicable or (y) Disqualified Stock or Preferred Stock, such Refinancing Indebtedness is Disqualified Stock or Preferred Stock; 

(4)      the aggregate principal amount (or, in the case of Disqualified Stock, the amount
thereof as determined in accordance with the definition of Disqualified Stock) of such Refinancing Indebtedness is equal to or less than the aggregate principal amount (or in the case of Disqualified Stock, the amount thereof as determined in
accordance with the definition of Disqualified Stock) then outstanding of the Indebtedness or Disqualified Stock being refinanced, refunded, renewed, replaced, defeased, discharged or retired plus all accrued interest on the Indebtedness or accrued
dividends on the Disqualified Stock, as the case may be, being refinanced, refunded, renewed, replaced, defeased, discharged or retired and all premiums, expenses and fees incurred in connection with such refinancing; and 

(5)      such Refinancing Indebtedness shall not include (x) Indebtedness of a
Restricted Subsidiary that is not a Guarantor that refinances Indebtedness of the Company or a Guarantor, or (y) Indebtedness of the Company or a Restricted Subsidiary that refinances Indebtedness of an Unrestricted Subsidiary; 

(xiv)      Indebtedness arising from the honoring by a bank or other financial institution
of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days of its Incurrence; 

(xv)       Indebtedness of the Company or any Restricted Subsidiary 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; 

(xvi)      Indebtedness of the Company or any Restricted Subsidiary 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; and 
  


 -53- 








 (xvii)      Indebtedness or Disqualified Stock
of the Company or any Restricted Subsidiary and Preferred Stock of any Restricted Subsidiary in an aggregate principal amount which, when aggregated with the principal amount or liquidation preference of all other Indebtedness, Disqualified Stock
and Preferred Stock then outstanding and Incurred pursuant to this clause (xvii) does not exceed the greater of (x) $25.0 million and (y) 3.5% of Consolidated Net Tangible Assets at the time of Incurrence, at any one time outstanding
(which Indebtedness may be incurred, in whole or in part, under a Credit Facility). 

(c)         Notwithstanding the foregoing, neither the Company nor any Guarantor may Incur
any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are used, directly or indirectly, to repay, prepay, redeem, defease, retire, refund or refinance any Subordinated Indebtedness unless such Indebtedness shall be subordinated
to the Securities or such Guarantor’s Guarantee, as applicable, to at least the same extent as such Subordinated Indebtedness. For purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness,
Disqualified Stock or Preferred Stock meets the criteria of more than one of the categories of Permitted Debt or is entitled to be Incurred pursuant to Section 4.03(a), the Company shall be permitted to divide or classify (or later divide,
classify or reclassify), in whole or in part in its sole discretion, such item of Indebtedness, Disqualified Stock or Preferred Stock in any manner that complies with this Section 4.03 and such item of Indebtedness, Disqualified Stock or
Preferred Stock shall be treated as having been Incurred pursuant to only one of the clauses in Section 4.03(b) or pursuant to Section 4.03(a); provided that all Indebtedness under the Credit Agreement outstanding on the Issue Date
shall be deemed to have been Incurred pursuant to clause (i) of Section 4.03(b) and the Company shall not be permitted to reclassify all or any portion of such Indebtedness. Accrual of interest, the accretion of accreted value, the
amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class, the
accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies shall not be deemed to be an Incurrence of Indebtedness for purposes of this
Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which are otherwise included in the determination of a particular amount of Indebtedness shall not be included in the determination of such
amount of Indebtedness; provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03. 

(d)          For purposes of determining compliance with any U.S. dollar-denominated
restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was
Incurred, in the case of term debt, or first committed or first Incurred (whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt; provided that if such Indebtedness is Incurred to refinance other Indebtedness
denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S.
dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such 
  

 -54- 








 
refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 

SECTION 4.04.        Limitation on Restricted Payments. 

(a)      The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly: 
 (i)      declare or pay any dividend or make any distribution on
account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests, including any payment made in connection with any merger or consolidation involving the Company (other than (A) dividends or distributions by the
Company payable solely in Equity Interests (other than Disqualified Stock) of the Company; or (B) dividends or distributions by a Restricted Subsidiary so long as, in the case of any dividend or distribution payable on or in respect of any
class or series of securities issued by a Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, the Company or a Restricted Subsidiary receives at least its pro rata share of such dividend or distribution in accordance with its
Equity Interests in such class or series of securities); 
 (ii)      purchase or
otherwise acquire or retire for value any Equity Interests of the Company or any Parent Company; 

(iii)     make any principal payment on, or redeem, repurchase, defease or otherwise acquire or
retire for value, in each case prior to any scheduled repayment or scheduled maturity, any Subordinated Indebtedness (other than the payment, redemption, repurchase, defeasance, acquisition or retirement of Subordinated Indebtedness in anticipation
of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such payment, redemption, repurchase, defeasance, acquisition or retirement; or 

(iv)      make any Restricted Investment 

(all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as “Restricted
Payments”), unless, at the time of such Restricted Payment: 

(1)      no Default or Event of Default shall have occurred and be continuing or would
occur as a consequence thereof; 
 (2)      immediately after giving effect to
such transaction on a pro forma basis, the Company could Incur $1.00 of additional Indebtedness under Section 4.03(a); and 

(3)      such Restricted Payment, together with the aggregate amount of all other
Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (including Restricted Payments permitted by clause (i) of Section 4.04(b), but excluding all other Restricted Payments permitted by
Section 4.04(b)), is less than the sum of, without duplication, 
  

 -55- 








 (A)      50% of the Consolidated Net Income
of the Company for the period (taken as one accounting period) from October 1, 2010 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted
Payment (or, in the case such Consolidated Net Income for such period is a deficit, minus 100% of such deficit), plus 

(B)      100% of the aggregate net proceeds, including cash and the Fair Market Value (as
determined in accordance with the next succeeding sentence) of property other than cash, received by the Company after the Issue Date from the issue or sale of Equity Interests of the Company (excluding (without duplication) Refunding Capital Stock,
Designated Preferred Stock, Excluded Contributions and Disqualified Stock), including Equity Interests issued upon conversion of Indebtedness or upon exercise of warrants or options (other than an issuance or sale to a Subsidiary of the Company or
an employee stock ownership plan or trust established by the Company or any of its Subsidiaries), plus 

(C)      without duplication of any amount included in clause (B) above, 100% of the
aggregate amount of contributions to the capital of the Company received in cash and the Fair Market Value (as determined in accordance with the next succeeding sentence) of all property other than cash received by the Company as a contribution to
its capital after the Issue Date (other than Excluded Contributions, Refunding Capital Stock, Designated Preferred Stock and Disqualified Stock), plus 

(D)      the principal amount of any Indebtedness, or the liquidation preference or
maximum fixed repurchase price, as the case may be, of any Disqualified Stock, of the Company or any Restricted Subsidiary thereof issued after the Issue Date (other than Indebtedness or Disqualified Stock issued to a Restricted Subsidiary) which
has been converted into or exchanged for Equity Interests in the Company or such Restricted Subsidiary (other than Disqualified Stock), plus 

(E)      the amount equal to the net reduction in Investments (other than Permitted
Investments) made by the Company or any of its Restricted Subsidiaries in any Person resulting from, and without duplication, (I) repurchases or redemptions of such Investments by such Person, proceeds realized upon the sale of such Investment
to an unaffiliated purchaser and repayments of loans or advances or other transfers of assets by such Person to the Company or any Restricted Subsidiary (including by way of dividend or distribution) or (II) the redesignation of Unrestricted
Subsidiaries as Restricted Subsidiaries or the merger or consolidation of an Unrestricted Subsidiary with and into the Company or any Restricted Subsidiary (valued in each case as provided in the definition of “Investment”) not to exceed,
in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any of its Restricted Subsidiaries in such 

 

 -56- 








 
Unrestricted Subsidiary, which amount was included in the calculation of Restricted Payments. 

The Fair Market Value of property other than cash covered by clauses (3)(B), (C), (D) and (E) of this Section 4.04(a)
shall be determined in good faith by the Company and in the event of property with a Fair Market Value in excess of $10 million, shall be set forth in a resolution approved by at least a majority of the Board of Directors of the Company.

 (b)      The provisions of Section 4.04(a) shall not prohibit: 

(i)      the payment of any dividend or distribution within 60 days after the date of
declaration thereof, if at the date of declaration such payment would have complied with the provisions of this Indenture; 

(ii)      (A) the redemption, repurchase, retirement or other acquisition of any
Equity Interests (“Retired Capital Stock”) of the Company, any Parent Company or any Guarantor or any Subordinated Indebtedness of the Company, any Parent Company or any Guarantor in exchange for, or out of the proceeds of the
substantially concurrent sale of, Equity Interests of the Company or any Parent Company or contributions to the equity capital of the Company or any Restricted Subsidiary (other than any Disqualified Stock or any Equity Interests sold to a
Subsidiary of the Company or to an employee stock ownership plan or any trust established by the Company or any of its Subsidiaries) (collectively, including any such contributions, “Refunding Capital Stock”); and (B) the
declaration and payment of accrued dividends on the Retired Capital Stock out of the proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company or to an employee stock ownership plan or any trust established by the
Company or any of its Subsidiaries) of Refunding Capital Stock; 
 (iii)      the
redemption, repurchase, defeasance or other acquisition or retirement of Subordinated Indebtedness of the Company or any Guarantor made by exchange for, or out of the proceeds of the substantially concurrent issuance of, new Indebtedness of the
Company or any Guarantor which is Incurred in accordance with Section 4.03 (with an Incurrence of such new Indebtedness being deemed substantially concurrent if such redemption, repurchase, defeasance, acquisition or retirement occurs not more
than 60 days after such Incurrence), so long as: 
 (A)      the principal amount
of such new Indebtedness does not exceed the principal amount of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired for value (plus all accrued and unpaid interest on such Subordinated Indebtedness and the
amount of any premiums required to be paid under the terms of the instrument governing the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired plus any fees and expenses incurred in connection therewith);

  

 -57- 








 (B)      such Indebtedness is subordinated to
the Securities or the related Guarantee, as the case may be, at least to the same extent as such Subordinated Indebtedness so redeemed, repurchased, defeased, acquired or retired for value; 

(C)      such Indebtedness has a final scheduled maturity date equal to or later than the
earlier of: (A) the final scheduled maturity date of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired and (B) 91 days following the last maturity date of any notes then outstanding; and

 (D)      such Indebtedness has a Weighted Average Life to Maturity equal to or
greater than the shorter of: (A) the remaining Weighted Average Life to Maturity of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired and (B) the Weighted Average Life to Maturity that would result
if all payments of principal on the Subordinated Indebtedness being redeemed, repurchased, defeased, acquired or retired that were due on or after the date that is 91 days following the last maturity date of any notes then outstanding were instead
due on such date; 
 (iv)      the repurchase, retirement or other acquisition for
value of Equity Interests of the Company or any Parent Company held by any future, present or former employee, director or consultant of the Company, any Parent Company or any Subsidiary of the Company, and any dividend payment or other distribution
by the Company or a Restricted Subsidiary to any Parent Company the proceeds of which are utilized for the repurchase, retirement or other acquisition for value of Equity Interests such Parent Company held by any future, present or former employee,
director or consultant of the Company, any Parent Company or any Subsidiary of the Company, in each case pursuant to any management equity plan or stock option plan or any other management or employee benefit plan or other agreement or arrangement;
provided, however, that the aggregate amounts paid under this clause (iv) do not exceed $5 million in any calendar year (with unused amounts in any calendar year being permitted to be carried over for the next calendar year);
provided further, however, that such amount in any calendar year may be increased by an amount not to exceed: 

(A)      the cash proceeds received by the Company or any of its Restricted Subsidiaries
from the sale of Equity Interests (other than Disqualified Stock) of the Company and, to the extent contributed to the capital of the Company, the Equity Interests of any Parent Company, in each case to members of management, directors or
consultants of the Company, any Parent Company or any Restricted Subsidiary after the Issue Date (provided that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend shall not increase
the amount available for Restricted Payments under Section 4.04(a)(3)); plus 

(B)      the cash proceeds of key man life insurance policies received by the Company and
its Restricted Subsidiaries after the Issue Date 
  

 -58- 








 (provided that the Company may elect to apply all or any portion of
the aggregate increase contemplated by clauses (A) and (B) above in any calendar year); 

(v)      the declaration and payment of dividends or distributions to holders of any class
or series of Disqualified Stock of the Company or any of its Restricted Subsidiaries issued or incurred in accordance with Section 4.03; 

(vi)      the declaration and payment of dividends or distributions to holders of any class
or series of Designated Preferred Stock (other than Disqualified Stock) issued after the Issue Date; provided, however, that (A) for the most recently ended four full fiscal quarters for which internal financial statements are
available immediately preceding the date of issuance of such Designated Preferred Stock, after giving effect to such issuance (and the payment of dividends or distributions) on a pro forma basis, the Company would have had a Fixed Charge Coverage
Ratio of at least 2.00 to 1.00 and (B) the aggregate amount of dividends declared and paid pursuant to this clause (vi) does not exceed the net cash proceeds actually received by the Company from any such sale of Designated Preferred Stock
(other than Disqualified Stock) issued after the Issue Date; 

(vii)      Restricted Payments consisting of the funding of one or more dividends or
distributions to any Parent Company for the purpose of funding one or more dividends or distributions to, repurchases of Capital Stock held by, or other transactions effecting a return of capital to, the holders of such Parent Company’s Capital

time of such Restricted Payment, at any one time outstanding; 
 (xii)      the
payment of dividends or distributions to any Parent Company for the purpose of funding the payment of dividends or distributions on such Parent Company’s common equity capital of up to $1 million per annum; and

retirement for value of Subordinated Indebtedness, Disqualified Stock or Preferred Stock of the Company and its Restricted Subsidiaries pursuant to provisions similar to those described under Section 4.06 and Section 4.08; provided
that, prior to such payment, purchase, redemption, defeasance or other acquisition or retirement for value, the Company (or a third party to the extent permitted by this Indenture) has made a Change of Control Offer or Asset Sale Offer, as the case
may be, with respect to the Securities as a result of 
  

 -59- 








 
such Change of Control or Asset Sale, as the case may be, and has repurchased all Securities validly tendered and not withdrawn in connection with such Change of Control Offer or Asset Sale
Offer, as the case may be; 
 provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted
under clauses (xi), (xii) and (xiii) of this Section 4.04(b), no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof. 

(c)      As of the Issue Date, all of the Company’s Subsidiaries shall be Restricted Subsidiaries.
The Company shall not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the definition of “Unrestricted Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary,
all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall be deemed to be Restricted Payments or Permitted Investments in an amount determined as set forth in the
last sentence of the definition of “Investments.” Such designation shall only be permitted if a Restricted Payment or Permitted Investment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition
of an Unrestricted Subsidiary. 
 SECTION 4.05.      Dividend and Other Payment Restrictions
Affecting Subsidiaries. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual
restriction on the ability of any Restricted Subsidiary to: 

(a)      (i) pay dividends or make any other distributions to the Company or any of
its Restricted Subsidiaries on its Capital Stock or (ii) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; 

(b)      make loans or advances to the Company or any of its Restricted Subsidiaries; or

 (c)      sell, lease or transfer any of its properties or assets to the Company
or any of its Restricted Subsidiaries, 
 except in each case for such encumbrances or restrictions existing under or by reason of: 

(1)      contractual encumbrances or restrictions in effect or entered into on the Issue
Date, including pursuant to the Credit Agreement; 
 (2)      this Indenture, the
Securities (and any Exchange Securities and guarantees thereof), the Guarantees and the Security Documents; 

(3)      applicable law or any applicable rule, regulation, order, approval, license,
permit or similar restriction; 
  

 -60- 








 (4)      any agreement or other instrument of
a Person acquired by the Company or any Restricted Subsidiary which was in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the Person, so acquired; 

(5)      contracts or agreements for the sale of assets, including customary restrictions
with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary; 

(6)      Permitted Additional Pari Passu Obligations or any other Secured Indebtedness
otherwise permitted to be Incurred pursuant to Sections 4.03 and 4.12 that limit the right of the debtor to dispose of the assets securing such Indebtedness; 

(7)      restrictions on cash or other deposits or net worth imposed by customers under
contracts entered into in the ordinary course of business; 
 (8)      customary
provisions in joint venture agreements and other similar agreements entered into (x) in the ordinary course of business or (y) with the approval of the Company’s Board of Directors, which limitations are applicable only to the assets,
property or Capital Stock that are the subject of such agreements; 

(9)      purchase money obligations for property acquired, construction loans for property
constructed and Capitalized Lease Obligations that impose restrictions of the type described in clause (c) above on the property so acquired, constructed or leased; 

(10)      customary provisions contained in leases, licenses, contracts and other similar
agreements entered into in the ordinary course of business that impose restrictions of the type described in clause (c) above on the property subject to such lease; 

(11)      other Indebtedness, Disqualified Stock or Preferred Stock of any Restricted
Subsidiary that is Incurred subsequent to the Issue Date pursuant to Section 4.03; provided that such encumbrances and restrictions contained in any agreement or instrument will not materially affect the Company’s ability to make
anticipated principal or interest payment on the Securities (as determined by the Company in good faith); 

(12)      any Restricted Investment not prohibited by Section 4.04 and any Permitted
Investment; 
 (13)      customary provisions in agreements of the type described
in the definition of “Hedging Obligations” permitted under this Indenture and entered into in the ordinary course of business; 

(14)      encumbrances and restrictions contained in contracts entered into in the ordinary
course of business, not relating to any Indebtedness, and that do not, individually 
  

 -61- 








 
or in the aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary or the ability of the Company or such Restricted Subsidiary to realize such value, or
to make any distributions relating to such property or assets in each case in any material respect; and 

(15)      any encumbrances or restrictions of the type referred to in clauses (a),
(b) and (c) above imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through
(14) above; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company, not materially more restrictive as a whole
with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

 For purposes of determining compliance with this Section 4.05, (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 Company or a Restricted Subsidiary to other Indebtedness Incurred by the Company or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances. 

SECTION 4.06.      Asset Sales. 

(a)      The Company shall not, and shall not permit any of its Restricted Subsidiaries to consummate an
Asset Sale, unless: 
 (1)      the Company or any of its Restricted Subsidiary,
as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value (as determined in good faith by the Company) of the assets sold or otherwise disposed of; 

(2)      except in the case of a Permitted Asset Swap, at least 75% of the consideration
therefor received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; provided that the amount of: 

(i)      any liabilities (as shown on the Company’s or any Restricted
Subsidiary’s most recent balance sheet or in the notes thereto) of the Company or any Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Securities) that are assumed by the transferee of any such assets,

 (ii)      any notes or other obligations or other securities or assets
received by the Company or any Restricted Subsidiary from such transferee that are converted by the Company 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), 
  

 -62- 








 (iii)      accounts receivable of a business
retained by the Company 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 

(iv)      any Designated Non-cash Consideration received by the Company or any of its
Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iv) that is at that time outstanding, not to exceed the greater
of (x) $15.0 million and (y) 2.5% of Consolidated Net Tangible 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) 
 shall each be deemed to be Cash Equivalents for the
purposes of this Section 4.06(a). 
 (3)      if such Asset Sale involves the
disposition of Collateral, the Company 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 Cash 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 Cash Proceeds, such property shall be made subject to the Note Liens. 

(b)      Within 365 days after the Company’s or any Restricted Subsidiary’s receipt of the
Net Cash Proceeds of any Asset Sale or Casualty or Condemnation Event, the Company or such Restricted Subsidiary may apply the Net Cash Proceeds from such Asset Sale or Casualty or Condemnation Event, at its option: 

(i)      to the extent such Net Cash Proceeds constitute proceeds from the sale of ABL
Priority Collateral, to repay Indebtedness under the Credit Agreement secured by such ABL Priority Collateral; 

(ii)      to the extent such Net Cash Proceeds constitute proceeds from the sale of Notes
Priority Collateral, to permanently repay, equally and ratably, the Securities and any Permitted Additional Pari Passu Obligations; 

(iii)      to permanently reduce Obligations under other Secured Indebtedness
(provided that if the Company or any Guarantor shall so reduce such Obligations, the Company shall equally and ratably reduce Obligations under the Securities and any Permitted Additional Pari Passu Obligations if the Securities and Permitted
Additional Pari Passu Obligations are then prepayable or, if the Securities may not then be prepaid, by 
  

 -63- 








 
making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus
accrued and unpaid interest, if any, the pro rata principal amount of Securities that would otherwise be prepaid) or Indebtedness of a Restricted Subsidiary that is not a Guarantor, in each case other than Indebtedness owed to the Company or an
Affiliate of the Company; 
 (iv)      to make an investment in any one or more
businesses, properties or assets (provided that if such investment is in the form of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Company), or to make capital
expenditures, in each case used or useful in a Similar Business; and/or 

(v)      to make an Investment in any one or more businesses, properties or assets
(provided that if such investment is in the form of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Company), that replace the properties and assets that are the
subject of such Asset Sale or Casualty or Condemnation Event; provided that with respect to the replacement or restoration of any property, equipment or assets of the Company that is the subject of a Casualty or Condemnation Event, if the
Company or the applicable Guarantor commences replacement or restoration of such property, equipment or assets of the Company within 365 days after receipt of the Net Cash Proceeds from such Casualty or Condemnation Event, the 365 day period shall
be extended for so long as the Company or the applicable Guarantor is diligently pursuing such replacement or restoration, subject to any force majeure event; provided, however, that if such Net Cash Proceeds are received in respect of Notes
Priority Collateral, such assets constitute Notes Priority Collateral. 
 In the case of clauses (iv) and (v) above, a binding
commitment shall be treated as a permitted application of the Net Cash Proceeds from the date of such commitment, provided that, in the event such binding commitment is later canceled or terminated for any reason before such Net Cash Proceeds
are so applied, the Company or such Restricted Subsidiary enters into another binding commitment within 180 days of such cancellation or termination of the prior binding commitment. 

Pending the final application of any such Net Cash Proceeds, the Company or the applicable Restricted Subsidiary may temporarily reduce
Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents or Investment Grade Securities. Any Net Cash Proceeds from any Asset Sale or Casualty or Condemnation Event that are not applied
as provided and within the time period set forth in this Section 4.06(b) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10 million, the Company shall make an offer
(an “Asset Sale Offer”) to all Holders of Securities and (x) in the case of Net Cash 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 Asset Sales or Casualty or Condemnation Event or (y) in the case of any other Net Cash Proceeds, to all holders of other Pari Passu Indebtedness

  

 -64- 








 
containing provisions similar to those set forth in this Indenture with respect to Assets Sales or Casualty or Condemnation Event, to purchase the maximum principal amount of such Securities and
Permitted Additional Pari Passu Obligations or Pari Passu Indebtedness, 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 (or such lesser price, if
any, as may be provided by the terms of such other Indebtedness), plus accrued and unpaid interest and Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this
Section 4.06 and, in the case of Securities, is an integral multiple of $2,000. The Company shall commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceed $10 million by
mailing the notice required pursuant to the terms of Section 4.06(f), with a copy to the Trustee and the Registrar. To the extent that the aggregate amount of Securities and such other Indebtedness tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes. If the aggregate principal amount of Securities and Permitted Additional Pari Passu Obligations or Pari Passu Indebtedness, as
appropriate, surrendered by holders thereof exceeds the amount of Excess Proceeds, the Registrar shall select the Securities and such other Indebtedness to be purchased in the manner described in Section 4.06(e). Upon completion of any such
Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 
 (c)      The Company
shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to an Asset Sale
Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations described in this Indenture by virtue thereof. 
 (d)      Not later than the date
upon which written notice of an Asset Sale Offer is delivered to the Trustee and the Registrar as provided above, the Company shall deliver to the Trustee and the Registrar an Officers’ Certificate as to (i) the amount of the Excess
Proceeds, (ii) the allocation of the Net Cash Proceeds from the Asset Sales or Casualty or Condemnation Event pursuant to which such Asset Sale Offer is being made and (iii) the compliance of such allocation with the provisions of
Section 4.06(b). Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer Period”), the Company shall deliver to the Registrar for cancellation the Securities or portions thereof that have been
properly tendered to and are to be accepted by the Company. The Paying Agent shall, on the date of purchase, mail or deliver payment to each tendering Holder in the amount of the purchase price. In the event that the Excess Proceeds delivered by the
Company to the Paying Agent is greater than the purchase price of the Securities tendered, the Paying Agent shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with
Section 4.06. 
 (e)      Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company at the address specified 
  

 -65- 








 
in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Registrar or the Company receives not later than two Business
Days prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered by the Holder for purchase and a statement that such Holder is
withdrawing his election to have such Security purchased. If at the end of the Offer Period more Securities are tendered pursuant to an Asset Sale Offer than the Company is required to purchase, selection of such Securities for purchase shall be
made by the Registrar in compliance with the requirements of the principal national securities exchange, if any, on which such Securities are listed, or if such Securities are not listed by lot or such other method as the Registrar shall deem fair
and appropriate (and in such manner as complies with applicable legal requirements); provided that, to the extent practicable, the Registrar shall not select Securities for purchase which would result in a Holder with a principal amount of
Securities less than the minimum denomination. 
 (f)        Notices of an Asset Sale
Offer shall be mailed by first class mail, postage prepaid, at least 30 but not more than 60 days before the purchase date to each Holder of Securities at such Holder’s registered address. If any Security 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 has been or is to be purchased. 

(g)        A new Security in principal amount equal to the unpurchased portion of any Security
purchased in part shall be issued in the name of the Holder thereof upon cancellation of the original Security. On and after the purchase date, unless the Company defaults in payment of the purchase price, interest shall cease to accrue on
Securities or portions thereof purchased. 
 SECTION 4.07.    Transactions with Affiliates.

Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of

as any such agreement together with all amendments thereto, taken as a whole, is not more disadvantageous to the Holders of the Securities in any material respect than the original agreement as in effect on the Issue Date) or any transaction
contemplated thereby; 
 (vi)      (A) transactions with customers, clients,
suppliers 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 fair to the Company and its
Restricted Subsidiaries in the reasonable determination of the Board of Directors or any executive officer of the Company, and are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party or
(B) transactions with joint ventures or Unrestricted Subsidiaries entered into in the ordinary course of business;

transaction meets the requirements of Section 4.07(a)(i); 

(xii)        transactions permitted by, and complying with, the provisions of
Section 5.01;

Company to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the
Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the terms contemplated in this Section 4.08; provided, however, that notwithstanding the occurrence

 In the event that at the time of any Change of Control the terms of the Credit Agreement restrict or prohibit the

to a Change of Control Offer made by the Company and such third party purchases all Securities validly tendered and not withdrawn under such Change of Control Offer.

for purchase, the Company shall also deliver an Officers’ Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section 4.08. A Security shall be deemed to have been
accepted for purchase at the time the Paying Agent, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. 

(g)        Prior to any Change of Control Offer, the Company shall deliver to the Trustee and
the Registrar an Officers’ Certificate stating that all conditions precedent contained herein to the right of the Company to make such offer have been complied with. 

(h)        The Company shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.08. To the extent that the provisions of any securities laws or regulations conflict

(i)        A Change of Control Offer may be made in advance of a Change of Control, and
conditioned upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

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 Company shall, and shall cause each of its existing and future Material Domestic
Subsidiaries to, 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:

SECTION 4.12.    Liens. 

(a)        The Company shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, create, Incur or suffer to exist any Lien (other than Permitted Liens) on any asset or property of the Company or such Restricted Subsidiary that secures any Indebtedness of the Company or such Restricted Subsidiary or any related
guarantees, except that the Company and the Restricted Subsidiaries may Incur or suffer to exist Liens on assets not constituting Collateral, so long as the Company or such Restricted Subsidiary effectively provides that the Securities or the
applicable 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 Subordinated Indebtedness) the Indebtedness or related guarantees secured by such Lien. 

(b)        Section 4.12(a) shall not require the Company or any Restricted Subsidiary to secure
the Securities if the relevant Lien consists of a Permitted Lien. Any Lien which is granted to secure the Securities or such Guarantee under Section 4.12(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 Securities or such Guarantee under Section 4.12(a). 
  

 -71- 








 SECTION 4.13.    Maintenance of Office or Agency. 

(a)        The Company shall maintain in the United States, an office or agency (which may be an
office of the Trustee or an affiliate of the Trustee or Registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture
may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the corporate trust office of the Trustee as set forth in Section 13.02. 

(b)        The Company may also from time to time designate one or more other offices or
agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of
any change in the location of any such other office or agency. 
 (c)        The
Company hereby designates the corporate trust office of the Trustee or its agent, as such office or agency of the Company in accordance with Section 2.04. 

SECTION 4.14.    Insurance. 

(a)        The Company will at all times maintain and will cause its Subsidiaries to maintain,

businesses of similar size, including liability, property and casualty loss, workers’ compensation and interruption of business insurance. 

(b)        The Company and Guarantors will 

(i)        cause any property and casualty insurance policies with respect to the
Mortgaged Property to be endorsed or otherwise amended to include a lender’s loss payable endorsement and cause all property policies and casualty insurance policies to name the Collateral Agent as loss payee; and such other provisions as may
be customary with companies in the same or similar businesses to protect their interests; deliver original or certified copies of all such policies or a certificate of an insurance broker to the Collateral Agent; cause each such policy to provide
that it shall not be canceled or not renewed upon less than 30 days’ prior written notice thereof by the insurer to the Collateral Agent; deliver to the Collateral Agent, prior to the cancellation or nonrenewal of any such policy of insurance,
a copy of a renewal or replacement policy (or other evidence of renewal of a policy previously delivered to the Collateral Agent), or insurance certificate with respect thereto, together with evidence of payment of the premium therefor;

 (ii)        if the area in which any
Building (as defined in Section 339.2 of the Federal Deposit Insurance Corporation Regulations and being codified to 12 CFR §339.2) 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), as determined by a Federal Emergency Management Agency Standard Flood Hazard Determination, the Company or its applicable Subsidiary shall maintain
flood insurance, as required in order to comply with the Flood Insurance Laws, with respect to such portion of the Mortgaged Property and naming the Collateral Agent for its benefit and the benefit of the Trustee and the Secured Creditors as
mortgagee/loss payee; 
 (iii)        with respect to all Mortgaged
Property, carry and maintain comprehensive liability insurance and coverage on a claims made basis against claims made for personal injury (including bodily injury, death and property damage) and umbrella liability insurance against any and all
claims, in each case in amounts and against such risks as are customarily maintained by companies engaged in the same or similar industry operating in the same or similar locations naming the Collateral Agent as an additional insured; and

 (iv)        notify the Collateral Agent promptly whenever any
separate insurance concurrent in form or contributing in the event of loss with that required to be maintained under this Section 4.14 is taken out by Company or any of the Guarantors; and promptly deliver to the Collateral Agent a duplicate
original copy of such policy or policies, or an insurance certificate with respect thereto. 

(c)        In connection with the covenants set forth in this Section 4.14, it is
understood and agreed that: 
 (i)        none of the Trustee, the
Collateral Agent nor their respective agents or employees shall be liable for any loss or damage insured by the insurance policies required to be maintained under this Section 4.14, it being understood that (A) the Company and Guarantors
shall look solely to their insurance companies or any other parties other than the aforesaid parties for the recovery of such loss or damage and (B) such insurance companies shall have no rights of subrogation against the Trustee, the
Collateral Agent or their agents or employees. If, however, the insurance policies do not provide waiver of subrogation rights against such parties, as required above, then each of Company, and the Guarantors hereby agree, to the extent permitted by
law, to waive, its right of recovery, if any, against the Trustee, the Collateral Agent and the Secured Parties and their agents and employees; and 

(ii)        the acceptance of any form, type or amount of insurance coverage by
the Trustee or Collateral Agent under this Section 4.14 shall in no event be deemed a representation, warranty or advice by the Trustee or Collateral Agent that such insurance is adequate for the purposes of the business of Company and the
Guarantors or the protection of their properties. 
 SECTION 4.15.    Maintenance of
Properties.  Subject to, and in compliance with, the provisions of Article 11 and the provisions of the applicable Security Documents, the

shall not be obligated to make such repairs, renewals, replacements, betterments and improvements if the failure to do so would not result (individually or in the aggregate) in a material adverse effect on the business of the Company and the
Guarantors, (ii) subject to Section 4.06, nothing in this Section 4.15 shall prevent the Company from discontinuing the use, operation or maintenance of any of such properties, or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Board of Directors of the Company desirable in the conduct of the business of the Company, and if such discontinuance or disposal is not adverse in any material respect to the Holders and (iii) subject to
Section 4.06, nothing in this Section 4.15 shall prevent the Company from discontinuing or disposing of any properties to the extent otherwise permitted by this Indenture. 

SECTION 4.16.    Real Property.  The Company shall notify the Collateral Agent within thirty
(30) days after the acquisition of any real property owned by the Company or any Guarantor that has a fair market value in excess of $2,000,000 that is not subject to the existing Mortgages (the “After-Acquired Real Property”),
and, within one hundred eighty (180) days after the acquisition of such owned real property, as such date may be extended by the Collateral Agent in its reasonable discretion, deliver to the Collateral Agent, with respect to such owned real
property, each of the documents described in Section 4.17 hereof (but excluding the documents described in paragraph (i) 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; provided that, for so long as the Credit Agreement is in effect, the Company shall not be required to deliver the documents described in Section 4.17 hereof with respect to
the After-Acquired Real Property in the event that the Company is not required to grant a Lien in such After-Acquired Real Property to the ABL Facility Collateral Agent pursuant to the Credit Agreement or the ABL Security Documents.

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
Company 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 such Mortgaged Property in favor of the
Collateral Agent for the benefit of the Secured Parties, securing the Secured Obligations, and such financing statements in respect of such Mortgage and any other instruments necessary to grant the interests purported to be granted by such Mortgage
(and to 
  

 -74- 








 
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 or policies of title insurance in an amount equal to the lesser of (i) the then-outstanding principal amount of all Securities and any additional Permitted Additional Pari Passu Obligations (the “Maximum

a related Notice of Default as specified below, 
 (e)        the
Company or any of its Restricted Subsidiaries fails to comply with any of its covenants or agreements in the Securities or this Indenture (other than those referred to in (a), (b), (c), or (d) above) and such failure continues for 60 days

because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $15 million, 
  

 -80- 








 (g)        the Company or any
Significant Subsidiary of the Company pursuant to or within the meaning of any Bankruptcy Law: 

(i)        commences a voluntary case; 

(ii)        consents to the entry of an order for relief against it in an
involuntary case; 
 (iii)        consents to the appointment of a
Custodian of it or for any substantial part of its property; or 

(iv)        makes a general assignment for the benefit of its creditors or takes
any equivalent action under any foreign laws relating to insolvency, 

(h)        a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that: 
 (i)        is for relief against the Company or
any Significant Subsidiary of the Company in an involuntary case; 

(ii)        appoints a Custodian of the Company or any Significant Subsidiary of
the Company or for all or substantially all of its property; or 

(iii)        orders the winding up or liquidation of the Company or any
Significant Subsidiary of the Company;

non-appealable judgments aggregating in excess of $15 million or its foreign currency equivalent (net of any amounts which are covered by enforceable insurance policies issued by solvent carriers), which judgments are not discharged, waived or
stayed for a period of 60 days following the entry thereof, 

(j)        the Guarantee of a Significant Subsidiary ceases to be in full force

Security Documents or otherwise cured within 60 days after receipt of a related Notice of Default as specified below. 
 The
foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule
or regulation of any administrative or governmental body. 
 The term “Bankruptcy Law” means Title 11,
United States Code, or any similar Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 

A Default under clause (c), (d), (e), (i) or (k) above shall not constitute an Event of Default until the Trustee
notifies the Company in writing or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company and the Trustee in writing of the Default and the Company does not cure such Default within the time specified in
clauses (c), (d), (e), (i) or (k) above after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” The Company shall deliver to
the Trustee, within thirty (30) days after the occurrence thereof, written notice of any event which is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Company is
taking or proposes to take with respect thereto. 
 SECTION
6.02.        Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(g) or (h) with respect to the Company) occurs and is continuing, the Trustee by
written notice to the Company or the Holders of at least 25% in principal amount of outstanding Securities by written notice to the Company and the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest on all the
Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(g) or (h) with respect to the Company occurs, the principal of,
premium, if any, and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the
Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or
interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

In the event of any Event of Default specified in Section 6.01(f), such Event of Default and all consequences thereof shall be
annulled, waived and rescinded, automatically and 
  

 -82- 








 without any action by the Trustee or the Holders of the Securities, if within 20 days after such Event
of Default arose the Company delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the holders thereof have rescinded or
waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the
principal amount of the Securities as described above be annulled, waived or rescinded upon the happening of any such events. 

SECTION 6.03.        Other Remedies.  If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities, this Indenture or the Security
Documents. 
 The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any
of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default.
No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
 SECTION
6.04.        Waiver of Past Defaults.  Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the
Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences except (a) a Default or Event of Default in the payment of the principal of or interest on a Security or (b) a Default or Event of
Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When a Default is waived, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. 

SECTION 6.05.        Control by Majority.  Subject to the terms of the Security
Documents, the Holders of a majority in principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on
the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action under this Indenture, the
Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 

 

 -83- 








 SECTION 6.06.        Limitation on Suits.

 (a)        Except to enforce the right to receive payment of principal, premium, if
any, or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless: 

(i)        the Holder gives to the Trustee written notice stating that an Event
of Default is continuing; 
 (ii)        the Holders of at least 25% in
principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy; 

(iii)        such Holder or Holders offer to the Trustee security or indemnity
reasonably satisfactory to it against any loss, liability or expense; 

(iv)        the Trustee does not comply with the request within 60 days after
receipt of the request and the offer of security or indemnity; and 

(v)        the Holders of a majority in principal amount of the Securities do not
give the Trustee a direction inconsistent with the request during such 60-day period. 

(b)        A Holder may not use this Indenture to prejudice the rights of another Holder or to
obtain a preference or priority over another Holder. 
 SECTION 6.07.        Rights
of the Holders to Receive Payment.  Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due
dates expressed or provided for in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

SECTION 6.08.        Collection Suit by Trustee.  If an Event of Default
specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any other obligor on the Securities for the whole amount then due and
owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Securities) and the amounts provided for in Section 7.07. 

SECTION 6.09.        Trustee May File Proofs of Claim.  The Trustee may file
such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Trustee (including counsel,
accountants, experts or such other professionals as the Trustee deems reasonably necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Company or any Guarantor, their creditors or their property,
shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other 
  

 -84- 








 
Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the
Trustee under Section 7.07. 
 SECTION
6.10.        Priorities.  Subject to the terms of the Security Documents, if the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in
the following order: 
 FIRST: to the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication
Agent for amounts due under Section 7.07; 
 SECOND: to Holders for amounts due and unpaid on the
Securities for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and 

THIRD: to the Company or, to the extent the Trustee collects any amount for any Guarantor, to such Guarantor. 

The Trustee, upon prior written notice to the Company and the Guarantors, may fix a record date and payment date for any payment to the
Holders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall send to each Holder and the Company a notice that states the record date, the payment date and amount to be paid. 

SECTION 6.11.        Undertaking for Costs.  In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of
the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the Securities then outstanding. 

SECTION 6.12.        Waiver of Stay or Extension Laws.  Neither the Company nor
any Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force,
which may affect the covenants or the performance of this Indenture; and the Company and each Guarantor (to the extent that it may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede
the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

 ARTICLE 7 

TRUSTEE 

SECTION 7.01.        Duties of Trustee. 

(a)        If an Event of Default has occurred and is continuing, the Trustee shall exercise the
rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b)        Except during the continuance of an Event of Default: 

(i)        the Trustee undertakes to perform such duties and only such duties as
are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii)        in the absence of bad faith on its part, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or
opinions required by any provision hereof to be provided to it, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 

(c)        The Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that: 

(i)        this paragraph does not limit the effect of paragraph (b) of this
Section 7.01; 
 (ii)        the Trustee shall not be liable for
any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; 

(iii)        the Trustee shall not be liable with respect to any action it takes
or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05; and

risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers. 

(d)        Every provision of this Indenture that in any way relates to the Trustee is subject

the extent required by law. 
 (g)        Every provision of this Indenture relating to
the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01 and, from the date on which this Indenture is qualified under the TIA, to the provisions of the TIA.

 SECTION 7.02.        Rights of Trustee. 

(a)        The Trustee may conclusively rely on any document believed by it to be genuine and to
have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 

(b)        Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel. 

(c)        The Trustee may act through agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care. 
 (d)        The Trustee shall not be
liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or
negligence. 
 (e)        The Trustee may consult with counsel of its own selection and
the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder
in good faith and in accordance with the advice or opinion of such counsel. 

(f)        The Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document unless requested in writing to do so by the Holders of not less than a
majority in principal amount of the Securities at the time outstanding, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such
further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or
investigation. 
 (g)        The Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to 

 

 -87- 








 
this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses, losses and liabilities which might be incurred
by it in compliance with such request or direction. 
 (h)        The rights,
privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, Deutsche Bank Trust Company Americas in each of its capacities hereunder, and each agent,
custodian and other Person employed to act hereunder. 
 (i)        In the event the
Company is required to pay Additional Interest, the Company will provide written notice to the Trustee of the Company’s obligation to pay Additional Interest no later than 15 days prior to the next interest payment date, which notice shall set
forth the amount of the Additional Interest to be paid by the Company. The Trustee shall not at any time be under any duty or responsibility to any Holders to determine whether the Additional Interest is payable and the amount thereof. 

SECTION 7.03.      Individual Rights of Trustee.  The Trustee in its individual or any
other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11. 
 SECTION
7.04.      Trustee’s Disclaimer.  The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, any Guarantee or the Securities, it shall
not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company or any Guarantor in this Indenture or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee’s certificate of authentication. The Trustee shall not be charged with knowledge of any Default or Event of Default under Sections 6.01(c), (d), (e), (f), (i), (j) or (k) or of
the identity of any Significant Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have received notice thereof in accordance with Section 13.02 from the Company, any Guarantor or
any Holder. 
 SECTION 7.05.      Notice of Defaults.  If a Default occurs and
is continuing and if it is actually known to a Trust Officer, the Trustee shall send to each Holder notice of the Default within the earlier of 90 days after it occurs or 30 days after it is actually known to a Trust Officer or written
notice of it is received by the Trustee. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Security, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is in the interests of the Holders. 
 SECTION
7.06.      Reports by Trustee to the Holders.  From the date on which this Indenture is qualified under the TIA, as promptly as practicable after each June 30 beginning with the June 30
following the date of this Indenture, and in any event within 12 months of the last such report, the Trustee shall send to each Holder a brief report dated as of such June 30 that complies with Section 313(a) of the TIA if and to the
extent required thereby. From the date on 
  

 -88- 








 
which this Indenture is qualified under the TIA, the Trustee shall also comply with Section 313(b)(2) of the TIA. 

A copy of each report at the time of its delivery to the Holders shall be filed with the SEC and each stock exchange (if any) on which
the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. 

SECTION 7.07.      Compensation and Indemnity. The Company shall pay to Deutsche Bank Trust Company
Americas, in each of its capacities, and through Deutsche Bank Trust Company Americas to Trustee from time to time reasonable compensation for its and Trustee’s services (it being understood all amounts set forth in the fee letter dated
September 24, 2010 between the Company and Deutsche Bank Trust Company Americas shall be deemed reasonable). The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee, Paying Agent, Registrar and Authentication Agent upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in the performance of services rendered under this Indenture, any
Security Document and any related document to which it is a party, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s, Paying
Agent’s, Registrar’s and Authentication Agent’s agents, counsel, accountants and experts. The Company and each Guarantor, jointly and severally shall indemnify the Trustee against any and all loss, liability, claim, damage or expense
(including reasonable attorneys’ fees and expenses) incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or
Guarantee against the Company or a Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by the Company, any Guarantor, any Holder or any other Person). The Trustee shall notify the
Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company or any Guarantor of its indemnity
obligations hereunder. The Company shall defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company and the
Guarantors, as applicable shall pay the fees and expenses of such counsel; provided, however, that the Company shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such
indemnified parties’ reasonable judgment, there is no conflict of interest between the Company and the Guarantors, as applicable, and such parties in connection with such defense. The Company need not reimburse any expense or indemnify against
any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, negligence or bad faith. 

To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee shall have a Lien prior
to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities. 

 

 -89- 








 The Company’s and the Guarantors’ payment obligations pursuant to this
Section 7.07 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee. Without prejudice to any other rights available to
the Trustee under applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(g) or (h) with respect to the Company, the expenses are intended to constitute expenses of administration under
the Bankruptcy Law. 
 SECTION 7.08.      Replacement of Trustee. 

(a)      The Trustee may resign at any time by so notifying the Company. The Holders of a majority in
principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company may remove the Trustee if: 

(i)       the Trustee fails to comply with Section 7.10; 

(ii)      the Trustee is adjudged bankrupt or insolvent; 

(iii)     a receiver or other public officer takes charge of the Trustee or its property; or

 (iv)     the Trustee otherwise becomes incapable of acting. 

If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. 

(b)      If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal
amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the
Company shall promptly appoint a successor Trustee. 
 (c)      A successor Trustee shall deliver
a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in
Section 7.07. 
 (d)      If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Securities may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

  

 -90- 








 (e)      If the Trustee fails to comply with
Section 7.10, unless the Trustee’s duty to resign is stayed as provided in Section 310(b) of the TIA, any Holder who has been a bona fide holder of a Security for at least six months may petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee. 

(f)      Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 
 SECTION
7.09.      Successor Trustee by Merger.  If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation
or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 

SECTION 7.10.      Eligibility; Disqualification.  The Trustee shall at all times satisfy
the requirements of Section 310(a) of the TIA. The Trustee shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with
Section 310(b) of the TIA, subject to its right to apply for a stay of its duty to resign under the penultimate paragraph of Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of
Section 310(b)(1) of the TIA any series of securities issued under this Indenture and any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if
the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met. 
 SECTION
7.11.      Preferential Collection of Claims Against Company.  The Trustee shall comply with Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA.
A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated. 

ARTICLE 8 

DISCHARGE OF INDENTURE; DEFEASANCE 

SECTION 8.01.      Discharge of Liability on Securities; Defeasance.  This Indenture
shall be discharged and shall cease to be of further effect (except as to surviving rights of registration or transfer or exchange of Securities, as expressly provided for in this Indenture) as to all outstanding Securities when: 

(a)        (i) all the Securities theretofore authenticated and delivered
(other than mutilated, lost, stolen or destroyed Securities which have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust) have been delivered to the Registrar for cancellation or (ii) all of the Securities (a) have become due and payable, (b) will become due and payable at their stated maturity within one year or
(c) if redeemable at the option of the Company, are to be 
  

 -91- 








 
called for redemption within one year under arrangements satisfactory to the Registrar for the giving of notice of redemption by the Registrar in the name, and at the expense, of the Company, and
the Company has irrevocably deposited or caused to be deposited with the Paying Agent funds in cash in U.S. Dollars, U.S. Government Obligations or a combination thereof in an amount sufficient in the written opinion of a investment banking firm,
appraisal firm or firm of independent public accountants delivered to the Trustee and Registrar (which delivery shall only be required if U.S. Government Obligations have been so deposited) to pay and discharge the entire Indebtedness on the
Securities not theretofore delivered to the Registrar for cancellation, for principal of, premium, if any, and interest on the Securities to the date of deposit together with irrevocable instructions from the Company directing the Paying Agent to
apply such funds to the payment thereof at maturity or redemption, as the case may be; 

(b)      the Company and/or the Guarantors have paid all other sums payable under this
Indenture; and 
 (c)      the Company has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with. 

Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (i) all of its obligations under the Securities
and this Indenture (with respect to such Securities) (“legal defeasance option”) or (ii) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.10, 4.11, 4.12, 4.14 and 4.15 and the operation of
Section 5.01 and Sections 6.01(c), 6.01(d), 6.01(e) (with respect to any Default under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.10, 4.11, 4.12, 4.14 and 4.15), 6.01(f), 6.01(g) (with respect to Significant Subsidiaries of the Company
only), 6.01(h) (with respect to Significant Subsidiaries of the Company only), 6.01(i), 6.01(j) and 6.01(k) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of
its covenant defeasance option. In the event that the Company terminates all of its obligations under the Securities and this Indenture (with respect to such Securities) by exercising its legal defeasance option or its covenant defeasance option,
the obligations of each Guarantor under its Guarantee of such Securities shall be terminated simultaneously with the termination of such obligations. 

If the Company exercises its legal defeasance option, payment of the Securities so defeased may not be accelerated because of an Event
of Default. If the Company exercises its covenant defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (with respect to
Significant Subsidiaries of the Company only), 6.01(h) (with respect to Significant Subsidiaries of the Company only), 6.01(i), 6.01(j) or 6.01(k) or because of the failure of the Company to comply with Section 5.01. 

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the
discharge of those obligations that the Company terminates. 
  

 -92- 








 (d)      Notwithstanding clauses (a) and (b) above,
the Company’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08, 11.07(e), 11.12 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections
7.07, 8.05, 8.06 and 11.12 shall survive such satisfaction and discharge. 
 SECTION
8.02.      Conditions to Defeasance. 
 (a)      The Company
may exercise its legal defeasance option or its covenant defeasance option only if: 

(i)       the Company irrevocably deposits in trust with the Paying Agent cash in U.S.
Dollars, U.S. Government Obligations or a combination thereof in an amount sufficient, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants, to pay the principal of, and premium
(if any) and interest on the applicable Securities when due at maturity or redemption, as the case may be, including interest thereon to maturity or such redemption date; 

(ii)      91 days pass after the deposit is made and during the 91-day period no
Default specified in Section 6.01(g) or (h) with respect to the Company occurs which is continuing at the end of the period; 

(iii)      the deposit does not constitute a default under any other material agreement
binding on the Company; 
 (iv)     the Company delivers to the Trustee an Opinion of
Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 

(v)      in the case of the legal defeasance option, the Company shall have delivered to
the Trustee an Opinion of Counsel stating that (1) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of this Indenture there has been a change in the applicable
Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and 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 deposit and defeasance had not occurred; 

(vi)     in the case of the covenant defeasance option, the Company shall have delivered to the
Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and 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 deposit and defeasance had not occurred; and 
  

 -93- 








 (vii)     the Company delivers to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities to be so defeased and discharged as contemplated by this Article 8 have been complied with.

 Notwithstanding the foregoing, the Opinion of Counsel required by the clause (vi) above need not be delivered if all Securities not
theretofore delivered to the Registrar for cancellation (x) have become due and payable or (y) will become due and payable at their Stated Maturity within one year under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company. 
 (b)      Before or
after a deposit, the Company may make arrangements satisfactory to the Trustee and Paying Agent for the redemption of such Securities at a future date in accordance with Article 3. 

SECTION 8.03.      Application of Trust Money.  The Paying Agent shall hold in trust
money or U.S. Government Obligations (including proceeds thereof) deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations in accordance with this Indenture to the payment
of principal of and interest on the Securities so discharged or defeased. 
 SECTION
8.04.      Repayment to Company.  Each of the Trustee and each Paying Agent shall promptly turn over to the Company upon request any money or U.S. Government Obligations held by it as provided in this
Article 8 which are, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants, in excess of the amount thereof which would then be required to be deposited to effect an equivalent
discharge or defeasance in accordance with this Article 8. 
 Subject to any applicable abandoned property law, the Paying
Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Company for payment as general
creditors, and the Paying Agent shall have no further liability with respect to such monies. 
 SECTION
8.05.      Indemnity for U.S. Government Obligations.  The Company shall pay and shall indemnify the Paying Agent against any tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or the principal and interest received on such U.S. Government Obligations. 
 SECTION
8.06.      Reinstatement.  If the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Securities so discharged or defeased shall be revived and reinstated as
though no deposit had occurred pursuant to this Article 8 until such time as the Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8;

  

 -94- 








 
provided, however, that, if the Company has made any payment of principal of or interest on, any such Securities because of the reinstatement of its obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Paying Agent. 

ARTICLE 9

in Section 163(f)(2)(B) of the Code; 
   (iv)      to add

   (v)      to further secure the Securities; 

  (vi)      to add to the covenants of the Company for the benefit of the Holders
or to surrender any right or power herein conferred upon the Company;

  (viii)      to comply with any requirement of the SEC in
connection with qualifying or maintaining the qualification of, this Indenture under the TIA; 

  (ix)      to evidence or provide for the acceptance of appointment under this
Indenture of a successor trustee; 
    (x)      to conform the

 -95- 








   (xii)      to provide for the
release of Collateral from the Liens of this Indenture and the Security Documents when permitted or required by the Security Documents, the Intercreditor Agreement or this Indenture; or 

(xiii)      to secure any Permitted Additional Pari Passu Obligations under the Security
Documents and to appropriately include the same in the Intercreditor Agreement. 
 Upon the request of the Company and the
Guarantors accompanied by a resolution of the Board of Directors of each of the Company and the Guarantors authorizing the execution of any supplemental indenture entered into to effect any such amendment, supplement or waiver, and upon receipt by
the Trustee of the documents described in Section 9.06, the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent shall join with the Company and the Guarantors in the execution of such supplemental indenture. After an
amendment under this Section 9.01 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of
an amendment under this Section 9.01. 
 SECTION 9.02.      With Consent of the
Holders. 
 (a)      The Company and the Trustee, Collateral Agent, Paying Agent, Registrar
and Authentication Agent may amend this Indenture or the Securities with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for Securities) and any past default or compliance with any provision of this Indenture, the Securities, the Guarantees or the Security Documents may be waived with the consent of the Holders of
a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange for, the Securities). However, without the consent of each Holder of an
outstanding Security affected, an amendment may not:

(x)         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 Holder of the Securities. 
 It shall not
be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof. 

(b)         Notwithstanding the requirements of Sections 9.02(a) and (b), 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
Securities or otherwise modifies the Intercreditor Agreement or other Security Documents in any manner adverse in any material respect to the Holders of the Securities will require the consent of the Holders of at least
66 2/3% in aggregate principal amount of the
Securities and any Permitted Additional Pari Passu Obligations then outstanding. 

(c)         After an amendment under this Section 9.02 becomes effective, the Company shall
mail to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02. 

SECTION 9.03.       Compliance with Trust Indenture Act.  From the date on which this
Indenture is qualified under the TIA, every amendment, waiver or supplement to this Indenture or the Securities shall comply with the TIA as then in effect. 

SECTION 9.04.       Revocation and Effect of Consents and Waivers. 

(a)         A consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the
Company certifying that the requisite principal amount of Securities have consented. 
  

 -97- 








 
After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt by the Company or the Trustee of consents by the
Holders of the requisite principal amount of securities, (ii) satisfaction of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such
amendment or waiver (or supplemental indenture) by the Company and the Trustee. 

(b)         The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph,
those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 

SECTION 9.05.       Notation on or Exchange of Securities.  If an amendment, supplement
or waiver changes the terms of a Security, the Company may require the Holder of the Security to deliver it to the Registrar. The Registrar may place an appropriate notation on the Security regarding the changed terms and return it to the Holder.
Alternatively, if the Company or the Registrar so determines, the Company in exchange for the Security shall issue and the Authentication Agent shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such amendment, supplement or waiver. 
 SECTION
9.06.       Trustee to Sign Amendments.  The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment, the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and shall be provided with, and (subject to
Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement
or waiver is the legal, valid and binding obligation of the Company and the Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03).

 SECTION 9.07.       Payment for Consent.  Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Securities unless such consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or
agreement. 
 SECTION 9.08.       Additional Voting Terms; Calculation of Principal
Amount.  Except as provided in the proviso to the first sentence of Section 9.02(a), all Securities issued 
  


 -98- 








 
under this Indenture shall vote and consent together on all matters (as to which any of such Securities may vote) as one class and no series of Securities will have the right to vote or consent
as a separate class on any matter. Determinations as to whether Holders of the requisite aggregate principal amount of Securities have concurred in any direction, waiver or consent shall be made in accordance with this Article 9 and
Section 2.14. 
 ARTICLE 10 

GUARANTEES 

SECTION 10.01.        Guarantees. 

(a)         Each Guarantor hereby jointly and severally, irrevocably and unconditionally
guarantees, as a primary obligor and not merely as a surety, to each Holder and to the Trustee and its successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise,
of all obligations of the Company under this Indenture (including obligations to the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent) and the Securities, whether for payment of principal of, premium, if any, or interest
on in respect of the Securities and all other monetary obligations of the Company under this Indenture and the Securities and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether
for fees, expenses, indemnification or otherwise under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any
Guaranteed Obligation. 
 (b)         Each Guarantor waives presentation to, demand of
payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each
Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other
agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or
any other agreement; (iv) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any Guarantor; (v) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor
of the Guaranteed Obligations; or (vi) any change in the ownership of such Guarantor, except as provided in Section 10.02(b). 

(c)         Each Guarantor hereby waives any right to which it may be entitled to have its
obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives any right to which it may be entitled to have the assets of the Company first be
used and depleted as payment of the Company’s or such Guarantor’s obligations hereunder prior to any amounts being claimed 

 

 -99- 








 
from or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Company be sued prior to an action being initiated against such
Guarantor. 
 (d)         Each Guarantor further agrees that its Guarantee herein
constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed
Obligations. 
 (e)         Except as expressly set forth in Sections 8.01(b),
10.02 and 10.06, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not
be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other
agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might
in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity. 

(f)         Except as set forth in Sections 8.01 and 10.02, each Guarantor agrees that its
Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Except as set forth in Sections 8.01 and 10.02, each Guarantor further agrees that its Guarantee herein shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of
the Company or otherwise. 
 (g)         In furtherance of the foregoing and not in
limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall
become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or
cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent
not prohibited by applicable law) and (iii) all other monetary obligations of the Company to the Holders and the Trustee in respect of the Guaranteed Obligations. 

(h)         Each Guarantor agrees that it shall not be entitled to any right of subrogation in
relation to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, 

 

 -100- 








 
on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the
purposes of any Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of
such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 10.01. 

(i)         Each Guarantor also agrees to pay any and all costs and expenses (including
reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01. 

(j)         Upon request of the Trustee, each Guarantor 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. 

(k)         Any Guarantee given by any direct or indirect parent of the Company may be released
and discharged from all obligations under this Article 10 at any time upon written notice to the Trustee from such direct or indirect parent of the Company. 

SECTION 10.02.     Limitation on Liability. 

(a)         Any term or provision of this Indenture to the contrary notwithstanding, the maximum
aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture or the Guarantee, as each relates to such Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

(b)         A Guarantee as to any Guarantor shall automatically terminate and be of no further
force or effect and such Guarantor shall be deemed to be released and discharged from all obligations under this Article 10 upon: 

(i)         the sale, disposition or other transfer (including through merger or
consolidation) of all of the Capital Stock of such Guarantor, all or substantially all the assets of such Guarantor or a portion of the Capital Stock of such Guarantor if as a result thereof such Guarantor is no longer a Restricted Subsidiary, in
each case if such sale, disposition or other transfer is made in compliance with this Indenture; 

(ii)        the Company designating such Guarantor to be an Unrestricted Subsidiary in
accordance with the provisions set forth in Section 4.04 and the definition of “Unrestricted Subsidiary”; 

(iii)       in the case of any Restricted Subsidiary which after the Issue Date is required
to guarantee the notes pursuant to Section 4.11, the release or discharge of the guarantee by such Restricted Subsidiary of the Indebtedness of the Company or its 

 

 -101- 








 
Domestic Subsidiary which resulted in the obligation to guarantee the Securities or the repayment of the Indebtedness of the Company or its Domestic Subsidiary which resulted in the obligation to
guarantee the Securities; 
 (iv)        the Company’s exercise of its
legal defeasance option or covenant defeasance option as described under Section 8.01 or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture; or 

(v)         upon the liquidation or dissolution of such Guarantor,
provided no Default or Event of Default has occurred or is continuing. 

(c)         A Guarantee also shall be automatically released upon the applicable Subsidiary
ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest securing Credit Agreement or other exercise of remedies in respect thereof. 

SECTION 10.03.     Successors and Assigns.  This Article 10 shall be binding upon each
Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 

SECTION 10.04.     No Waiver.  Neither a failure nor a delay on the part of either the Trustee or
the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights,
remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

 SECTION 10.05.     Modification.  No modification, amendment or waiver of any provision
of this Article 10, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances. 

SECTION 10.06.     Execution of Supplemental Indenture for Future Guarantors.  Each Subsidiary and
other Person which is required to become a Guarantor pursuant to Section 4.11 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit D hereto pursuant to which such Subsidiary or other
Person shall become a Guarantor under this Article 10 and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel
and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary or other Person and that, subject to the application of bankruptcy, insolvency, moratorium,
fraudulent conveyance or 
  

 -102- 








 
transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such
Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request. 

SECTION 10.07.     Non-Impairment.  The failure to endorse a Guarantee on any Security shall not
affect or impair the validity thereof.

not to be subject to any requirement pursuant to Rule 3-16 of Regulation S-X under the Securities Act to file separate financial statements with the SEC (or any other governmental agency), the Capital Stock and other securities of any Guarantor
shall not be included in the Collateral with respect to the Securities (or any Permitted Additional Pari Passu Obligations outstanding) so affected and shall not be subject to the Liens securing such Securities and any Permitted Additional Pari
Passu Obligations. Upon receipt of an Officers’ Certificate from the Company as described in Section 11.04 below, and any necessary or proper instruments of termination, satisfaction or release prepared by the Company, the Collateral Agent

Guarantor has sold, exchanged, or otherwise disposed of or proposes to sell, 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 Company or any
Guarantor, and the Company or such Guarantor requests the Trustee to furnish a written disclaimer, release or quitclaim of any interest in such property under this Indenture, the applicable Guarantee and the

  

 -105- 








 
Security Documents, upon receipt of an Officers’ Certificate and Opinion of Counsel to the effect that such release complies with Section 11.03 and specifying the provision in
Section 11.03 pursuant to which such release is being made (upon which the Trustee may exclusively and conclusively rely), the Trustee shall execute, acknowledge and deliver to the Company or such Guarantor (or instruct the Collateral Agent to
do the same) such an instrument in the form provided by the Company, and providing for release without recourse and shall take such other action as the Company or such Guarantor may reasonably request and as necessary to effect such release.

 SECTION 11.05.     Possession and Use of Collateral.  Subject to the provisions of the
Security Documents, the Company 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, 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 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 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 4.06 and 5.01. 
 SECTION 11.06.     Reports

of the Security Documents, to be complied with. 
 (b)         Any release of
Collateral permitted by Section 11.03 shall be deemed not to impair the Liens under this Indenture and the Security Agreement and the other Security Documents in contravention thereof. From the date on which this Indenture is qualified under
the TIA, any certificate or opinion required under Section 314(d) of the TIA may be made by an officer or legal counsel, as applicable, of the Company except in cases where Section 314(d) of the TIA requires that such certificate or
opinion be made by an independent Person, which Person shall be an independent engineer, appraiser or other expert selected by the Company. 

(c)         From the date on which this Indenture is qualified under the TIA, notwithstanding
anything to the contrary in this Section 11.06, the Company and the Guarantors shall not be required to comply with all or any portion of Section 314(d) of the TIA if they reasonably determine that under the terms of Section 314(d) of
the TIA or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of Section 314(d) of the TIA is inapplicable to any release or series
of releases of Collateral. 
  

 -106- 








 SECTION 11.07.  Collateral Agent. 

(a)        The Trustee and each of the Holders by acceptance of the Securities hereby
acknowledge the Company’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 Securities 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 11.07. The provisions of this
Section 11.07 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor the Company 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 11.03. 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 Company 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 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 have and may use its sole discretion with respect to exercising 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 Six, 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 without negligence or willful misconduct. 

(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 negligence or willful misconduct) or under or in connection with any Security
Document or the transactions contemplated thereby (except for its own 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

  

 -107- 








 
agreement made by the Company 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 Company 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 Company or any Guarantor. 

(d)        The Collateral Agent shall not be deemed to have 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 Company 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 Six (subject to this Section 11.07); 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 11.07(e). The Collateral Agent may resign in writing at any time by so
notifying the Company, 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 Company 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 Company 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 Securities) are incurred. If a successor Collateral Agent does not take office within 10 days after the retiring Collateral Agent
resigns or is removed, the retiring Collateral Agent, the Company or the holders of at least 10% in principal amount of the then outstanding principal amount of (x) the Securities (other than any Additional Securities 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

  

 -108- 








 
Obligations executed a joinder to the Security Agreement) may petition any court of competent jurisdiction 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 Company. 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 11.07(e), the Company’s obligations under this Section 11.07 and Section 11.12 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 by the
Holders and the Holders by acquiring the Securities and deemed to have authorized the Trustee, as applicable, to (i) 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 Securities 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)        The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the
Holders to assure that the Collateral exists or is owned by the Company 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 
  

 -109- 








 
in any manner it may deem appropriate, in its sole discretion given the Collateral Agent’s own interest in the Collateral, and that the Collateral Agent shall have no other duty or liability
whatsoever to the Trustee or any Holder 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 Company
(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. 

(j)        Notwithstanding anything to the contrary in this Indenure (including this Article
11), 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 6(B) of the definition thereof. Upon the request of the Company, 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 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 Company
pursuant to the preceding sentence shall be evidenced by a certificate from an officer of the Company which certificate shall certify that (1) the Permitted Liens in question do not materially adversely affect or impair (A) the business
operations of the Company 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. 

SECTION 11.08.    Purchaser Protected.  No purchaser or grantee of any property or rights
purporting to be released shall be bound to ascertain the authority of the Collateral Agent or Trustee to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority so long as the
conditions set forth in Section 11.04 have been satisfied. 
 SECTION 11.09.    Authorization of
Actions to Be Taken by the Collateral Agent Under the Security Documents.  The Holders of Securities agree that the Collateral Agent shall be entitled to the rights, privileges, protections, immunities, indemnities and benefits
provided to the Collateral Agent by the Security Documents. Furthermore, each holder of a Security, by 
  

 -110- 








 
accepting such Security, consents to the terms of and authorizes and directs the Trustee (in each of its capacities) and the Collateral Agent to enter into and perform the Security Documents in
each of its capacities thereunder. 
 SECTION 11.10.    Authorization of Receipt of Funds by the Trustee
Under the Security Agreement.  The Trustee is authorized to receive any funds for the benefit of Holders distributed under the Security Documents to the Trustee, to apply such funds as provided in Section 6.10. 

SECTION 11.11.    Powers Exercisable by Receiver or Collateral Agent.  In case the Collateral shall
be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Company or any Guarantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by
such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or any Guarantor, as applicable, or of any officer or officers thereof required by the provisions
of this Article 11. 
 SECTION 11.12.    Compensation and Indemnification.  The Collateral
Agent shall be entitled to the compensation and indemnification set forth in Section 7.07 (with the references to the Trustee therein being deemed to refer to the Collateral Agent).

AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN

Definitive Security, the Registrar shall permit the Holder thereof to exchange such Transfer Restricted Definitive Security for a Definitive Security that does not bear the legends set forth above and rescind any restriction on the transfer of such
Transfer Restricted Definitive Security if the Holder certifies in writing to the Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Initial
Security). 
 (iii)        After a transfer of any Initial Securities during the period

	1.	Interest 


(a)        TPC GROUP LLC, a Texas limited liability company (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company shall pay
interest semiannually on April 1 and October 1 of each year, commencing April 1, 2011. Interest on the Securities shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been
paid or duly provided for, from October 5,
2010a
 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal at the rate borne by
the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. 

(b)        Registration Rights Agreement.  The Holder of this Security is
entitled to the benefits of a Registration Rights Agreement, dated as of October 5, 2010, among the Company, the Guarantors and the Initial Purchasers. 
  

	2.	Method of Payment 

 The
Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders at the close of business on the March 15 or September 15 next preceding the interest payment date even if Securities are
canceled after the record date and on or before the interest payment date (whether or not a Business Day). The Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal, premium, if any, and
interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, 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 Company will make all payments in respect of a certificated Security (including
principal, premium, if any, and interest), at the office of each Paying Agent, except that, at the option of the Company, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the

	4.	Indenture 

 The Company
issued the Securities under an Indenture dated as of October 5, 2010 (the “Indenture”), among the Company, the Guarantors, the Paying Agent and Wilmington Trust Company as the trustee (the “Trustee”). The terms
of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the
“TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and the Holders are referred to the
Indenture and the TIA for a statement of such terms and provisions. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

The Securities are senior secured obligations of the Company. This Security is one of the Initial Securities referred to in the
Indenture. The Securities include the Initial Securities and any Exchange Securities issued in exchange for Initial Securities pursuant to the Indenture. The Initial Securities and any Exchange Securities are treated as a single class of securities
under the Indenture. The Indenture imposes certain limitations on the ability of the Company 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 Company 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 Company 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 Securities and all other amounts payable by the Company under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the
Indenture, the Guarantors have, jointly and severally, unconditionally guaranteed the Guaranteed Obligations on a senior secured basis pursuant to the terms of the Indenture.

	5.	Optional Redemption 


Except as set forth in the following three paragraphs, the Securities shall not be redeemable at the option of the Company prior to

prices (expressed as a percentage of principal amount), plus accrued and unpaid interest and Additional Interest, if any, to the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on
the relevant interest payment date), if redeemed during the 12-month period commencing on October 1 of the years set forth below:

	 2014
	  	104.125%

	  	102.063%
	 2016 and thereafter
	  	100.00%

 In addition, at
any time prior to October 1, 2013, the Company may redeem the Securities at its option, in whole at any time or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of
the principal amount of the Securities redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if any, to, the applicable redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date). 
 In addition, at any time and from time to time
prior to October 1, 2013, the Company may redeem in the aggregate up to 10.0% of the original aggregate principal amount of the Securities in any twelve-month period at a redemption price of 103%, plus accrued and unpaid interest and Additional
Interest, if any, to the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). 

Notwithstanding the foregoing, at any time and from time to time on or prior to October 1, 2013, the Company may redeem in the
aggregate up to 35% of the original aggregate principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities) with the net cash proceeds of one or more Equity Offerings by the Company or a
contribution to the capital of the Company from the net proceeds of one or more Equity Offerings by a Parent Company, at a redemption price (expressed as a percentage of the principal amount thereof) equal to 108.25% plus, accrued and unpaid
interest and Additional Interest, if any, to the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that at
least 65% of the original aggregate principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities) must remain outstanding after each such redemption; and provided, further, that such
redemption shall occur within 120 days after the date on which any such 
  

 -7- 








 
Equity Offering is consummated upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities being redeemed and otherwise in accordance with the procedures set
forth in the Indenture. 
 In connection with any redemption of Securities (including with the net cash proceeds of an Equity
Offering), any such redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including any related Equity Offering. 

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 Company’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. 
  

	6.	Sinking Fund 

 The
Securities are not subject to any sinking fund. 
  

	7.	Notice of Redemption 


Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the redemption date
to each Holder of Securities to be redeemed at his, her or its registered address or otherwise in accordance with the procedures of The Depository Trust Company. Securities in denominations larger than $2,000 may be redeemed in part but only in
whole multiples of $1,000 to the extent practicable. If money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with a Paying Agent on
or before the redemption date and certain other conditions are satisfied, on and after such date, interest ceases to accrue on such Securities (or such portions thereof) called for redemption. 

 

	8.	Repurchase of Securities at the Option of Holders upon Change of Control and Asset Sales 


Upon the occurrence of a Change of Control, each Holder shall have the right, subject to certain conditions specified in the Indenture,
to cause the Company to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right
of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date), as provided in, and subject to the terms of, the Indenture. 

In accordance with Section 4.06 of the Indenture, the Company will be required to offer to purchase Securities upon the occurrence
of certain events.

The Securities are in registered form, without coupons, in denominations of $2,000 and any integral multiple of $1,000 in excess
thereof. A Holder shall register the transfer of or exchange of Securities in accordance with the Indenture. Upon any registration of transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security
to be redeemed in part, the portion of the Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to a selection of Securities to be redeemed. 

 

	10.	Persons Deemed Owners 


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

 

	11.	Unclaimed Money 

 If
money for the payment of principal or interest remains unclaimed for two years, the Paying Agent shall pay the money back to the Company at its written request unless an abandoned property law designates another Person. After any such payment, the
Holders entitled to the money must look to the Company for payment as general creditors and the Paying Agent shall have no further liability with respect to such monies. 

 

	12.	Discharge and Defeasance 


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

 

	13.	Amendment, Waiver

consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities (voting as a single class) and (ii) any past default or compliance with any provisions may be waived with the written consent of the
Holders of at least a majority in principal amount of the outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5 of the Indenture; (iii) to provide for uncertificated Securities in addition to or in place of certificated Securities; provided,
however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code; (iv) to
add additional Guarantees with respect to the Securities or to secure the Securities or to evidence 
  

 -9- 








 
the release of any Guarantor from its Guarantee and under the Security Documents as provided in the Indenture; (v) to further secure the Securities; (vi) to add to the covenants of the
Company for the benefit of the Holders or to surrender any right or power conferred upon the Company in the Indenture; (vii) to comply with any requirement of the SEC in connection with qualifying, or maintaining the qualification of, the
Indenture under the TIA; (viii) to evidence or provide for the acceptance of appointment under the Indenture of a successor trustee; (ix) to conform the text of the Indenture, the Securities or the Guarantees to any provision of the
“Description of Notes” in the Offering Memorandum; (x) to provide for the issuance of the Exchange Securities or Additional Securities, which shall have terms substantially identical in all material respects to the Initial Securities,
and which shall be treated, together with any outstanding Initial Securities, as a single issue of securities; (xi) to provide for the release of Collateral from the Liens of the Indenture and the Security Documents when permitted or required
by the Security Documents, the Intercreditor Agreement or the Indenture; or (xii) to secure any Permitted Additional Pari Passu Obligations under the Security Documents and to appropriately include the same in the Intercreditor Agreement.

  

	14.	Defaults and Remedies 


If an Event of Default occurs (other than an Event of Default of the Company under Section 6.01(g) or (h)) occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities, in each case, by notice to the Company, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Securities to
be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs, the principal of, premium, if any, and interest on all the Securities shall become immediately due and payable
without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Securities may rescind any such acceleration with respect to the Securities
and its consequences. 
 If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise
any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense and certain other
conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Securities unless (i) such Holder has
previously given the Trustee notice that an Event of Default is continuing, (ii) the Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee in writing to pursue the remedy, (iii) such Holders
have offered the Trustee reasonable security or indemnity against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity
and (v) the Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the Holders of a majority in
principal amount of the outstanding Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.

  

 -10- 








 
The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that
would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not
taking such action. 
  

	15.	Security Documents and Intercreditor Agreement 


The obligations of the Company and the Guarantors under the Indenture, the Securities and the Guarantees by the Guarantors are secured
by a Lien on the Collateral pursuant to the Security Documents. The provisions of the Indenture and the Security Documents are subject to the Intercreditor Agreement. 
  

	16.	Trustee Dealings with the Company 


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

  

	17.	No Recourse Against Others 


No director, officer, employee, incorporator or holder of any equity interests in the Company or any Guarantor, as such, shall have any
liability for any obligations of the Company or any Guarantor under the Securities, the Indenture or the Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Securities by
accepting a Security waives and releases all such liability.

Security shall not be valid until an authorized signatory of the Authentication Agent manually signs the certificate of authentication on the other side of this Security. 

 

	19.	Abbreviations

1/4% Senior Secured Note due 2017 
  

	1.	Interest 

 TPC GROUP
LLC, a Texas limited liability company (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this
Security at the rate per annum shown above. The Company shall pay interest semiannually on April 1 and October 1 of each year, commencing April 1, 2011. Interest on the Securities shall accrue from the most recent date to which
interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from October 5,
2010a
 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal at the rate borne by
the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. 
  

	2.	Method of Payment 

 The
Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders at the close of business on the March 15 or September 15 next preceding the interest payment date even if Securities are
canceled after the record date and on or before the interest payment date (whether or not a Business Day). The Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal, premium, if any, and
interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and
interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depositary. The Company will make all payments in respect of a certificated Security (including
principal, premium, if any, and interest), at the office of a Paying Agent, except that, at the option of the Company, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided,
however, that payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, 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 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 Paying Agent may accept in its discretion).

 -4- 








 Initially, Deutsche Bank Trust Company Americas will act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent or Registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 

 

	4.	Indenture 

 The Company
issued the Securities under an Indenture dated as of October 5, 2010 (the “Indenture”), among the Company, the Guarantors, the Paying Agent and Wilmington Trust Company, as trustee (the “Trustee”). The terms of the
Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”).
Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and the Holders are referred to the Indenture and the TIA for a
statement of such terms and provisions. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

The Securities are senior secured obligations of the Company. This Security is one of the Exchange Securities referred to in the
Indenture. The Securities include the Initial Securities, the Additional Securities and any Exchange Securities issued in exchange for the Initial Securities pursuant to the Indenture. The Initial Securities and Exchange Securities are treated as a
single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of the Company 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 Company 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 Company 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, if any, on the Securities and all other amounts payable by the Company under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise,
according to the terms of the Securities and the Indenture, the Guarantors have, jointly and severally, unconditionally guaranteed the Guaranteed Obligations on a senior secured basis pursuant to the terms of the Indenture. 

 

	5.	Optional Redemption 


Except as set forth in the following three paragraphs, the Securities shall not be redeemable at the option of the Company prior to
October 1, 2013. Thereafter, the Securities shall be redeemable at the option of the Company, in whole at any time or in part from time to time, upon on not less than 30 nor more than 60 days’ prior notice, at the following redemption
prices (expressed as a percentage of principal amount), plus accrued and unpaid interest and 
  

 -5- 








 
Additional Interest, if any, to the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if
redeemed during the 12-month period commencing on October 1 of the years set forth below: 
  

			
	 Year
	  	Redemption Price
		
	 2013
	  	106.188%
	 2014
	  	104.125%
	 2015
	  	102.063%
	 2016 and thereafter
	  	100.00%

 In addition, at
any time prior to October 1, 2013, the Company may redeem the Securities at its option, in whole at any time or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of
the principal amount of the Securities redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if any, to, the applicable redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date). 
 In addition, at any time and from time to time
prior to October 1, 2013, the Company may redeem in the aggregate up to 10.0% of the original aggregate principal amount of the Securities in any twelve-month period at a redemption price of 103%, plus accrued and unpaid interest and Additional
Interest, if any, to the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). 

Notwithstanding the foregoing, at any time and from time to time on or prior to October 1, 2013, the Company may redeem in the
aggregate up to 35% of the original aggregate principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities) with the net cash proceeds of one or more Equity Offerings by the Company or a
contribution to the capital of the Company from the net proceeds of one or more Equity Offerings by a Parent Company, at a redemption price (expressed as a percentage of the principal amount thereof) equal to 108.25% plus, accrued and unpaid
interest and Additional Interest, if any, to the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that at
least 65% of the original aggregate principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities) must remain outstanding after each such redemption; and provided, further, that such
redemption shall occur within 120 days after the date on which any such Equity Offering is consummated upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities being redeemed and otherwise in accordance with the
procedures set forth in the Indenture. 
 In connection with any redemption of Securities (including with the net cash proceeds
of an Equity Offering), any such redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including any related Equity Offering. 
  


 -6- 








 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 Company’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. 

 

	6.	Sinking Fund 

 The
Securities are not subject to any sinking fund. 
  

	7.	Notice of Redemption 


Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the redemption date to
each Holder of Securities to be redeemed at his, her or its registered address or otherwise in accordance with the procedures of The Depository Trust Company. Securities in denominations larger than $2,000 may be redeemed in part but only in whole
multiples of $1,000 to the extent practicable. If money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with a Paying Agent on or
before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption. 

 

	8.	Repurchase of Securities at the Option of the Holders upon Change of Control and Asset Sales 


Upon the occurrence of a Change of Control, each Holder shall have the right, subject to certain conditions specified in the Indenture,
to cause the Company to repurchase all or any part of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right
of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date), as provided in, and subject to the terms of, the Indenture. 

In accordance with Section 4.06 of the Indenture, the Company will be required to offer to purchase Securities upon the occurrence
of certain events. 
  

	9.	Denominations; Transfer; Exchange 


The Securities are in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.
A Holder shall register the transfer of or exchange of Securities in accordance with the Indenture. Upon any registration of transfer or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the 
  

 -7- 








 
Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to a selection of Securities to be redeemed. 

 

	10.	Persons Deemed Owners 


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

 

	11.	Unclaimed Money 

 If
money for the payment of principal or interest remains unclaimed for two years, the Paying Agent shall pay the money back to the Company at its written request unless an abandoned property law designates another Person. After any such payment, the
Holders entitled to the money must look to the Company for payment as general creditors and the Paying Agent shall have no further liability with respect to such monies. 

 

	12.	Discharge and Defeasance 


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

 

	13.	Amendment, Waiver 


Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written
consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities (voting as a single class) and (ii) any past default or compliance with any provisions may be waived with the written consent of the
Holders of at least a majority in principal amount of the outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply with Article 5 of the Indenture; (iii) to provide for uncertificated Securities in addition to or in place of certificated Securities; provided,
however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code; (iv) to
add additional Guarantees with respect to the Securities or to secure the Securities or to evidence the release of any Guarantor from its Guarantee and under the Security Documents as provided in the Indenture; (v) to further secure the
Securities; (vi) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power conferred upon the Company in the Indenture; (vii) to comply with any requirement of the SEC in connection with
qualifying, or maintaining the qualification of, the Indenture under the TIA; (viii) to evidence or provide for the acceptance of appointment under the Indenture of a successor trustee; (ix) to conform the text of the Indenture, the
Securities or the Guarantees to any provision of the “Description of Notes” in the Offering Memorandum; (x) to provide for the issuance of the Exchange Securities or Additional Securities, which shall have terms substantially
identical in all material respects to the 
  

 -8- 








 
Initial Securities, and which shall be treated, together with any outstanding Initial Securities, as a single issue of securities; (xi) to provide for the release of Collateral from the
Liens of the Indenture and the Security Documents when permitted or required by the Security Documents, the Intercreditor Agreement or the Indenture; or (xii) to secure any Permitted Additional Pari Passu Obligations under the Security
Documents and to appropriately include the same in the Intercreditor Agreement. 
  

	14.	Defaults and Remedies 


If an Event of Default occurs (other than an Event of Default of the Company under Section 6.01(g) or (h)) and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the outstanding Securities, in each case, by notice to the Company, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Securities to be due and
payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs, the principal of, premium, if any, and interest on all the Securities shall become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Securities may rescind any such acceleration with respect to the Securities and its
consequences. 
 If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of
the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense and certain other conditions
are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Securities unless (i) such Holder has previously given
the Trustee notice that an Event of Default is continuing, (ii) the Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee in writing to pursue the remedy, (iii) such Holders have offered the
Trustee reasonable security or indemnity against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity and (v) the
Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the Holders of a majority in principal amount
of the outstanding Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may
refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under
the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 

 

	15.	Security Documents and Intercreditor Agreement 


The obligations of the Company and the Guarantors under the Indenture, the Securities and the Guarantees by the Guarantors are secured
by a Lien on the Collateral pursuant to 
  

 -9- 








 
the Security Documents. The provisions of the Indenture and the Security Documents are subject to the Intercreditor Agreement. 

 

	16.	Trustee Dealings with the Company 


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

  

	17.	No Recourse Against Others 


No director, officer, employee, incorporator or holder of any equity interests in the Company or of any Guarantor or any direct or
indirect parent corporation, as such, shall have any liability for any obligations of the Company or the Guarantors under the Securities, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Securities by accepting a Security waives and releases all such liability. 
  

	18.	Authentication 

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

 

	19.	Abbreviations 


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

	20.	Governing Law 

 THIS
SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
  

	21.	CUSIP Numbers, ISINs and Common Codes

 1.        We are an institutional
“accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an
institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to the Securities in the normal course
of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment. 

2.        We understand that the Securities have not been registered under the Securities Act
and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities
prior to the date that is one year after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction
Termination Date”) only (a) to the Company, (b) pursuant to a registration statement that has been declared effective under the Securities Act, (c) in a transaction complying








 
with the requirements of Rule 144A under the Securities Act (“Rule 144A”), to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a
“QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United
States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own
account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Securities of $250,000, or (f) pursuant to any other available exemption from the registration requirements of
the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company, the Registrar and the Trustee, which shall provide, among other things, that the
transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Securities for investment purposes and not for distribution in
violation of the Securities Act. Each purchaser acknowledges that the Company, the Registrar and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to
clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Company, the Registrar and the Trustee.
