of making the computation referred to above, Investments, acquisitions, dispositions, mergers, amalgamations, consolidations and discontinued operations (as determined in accordance with GAAP), in each case with respect to an operating unit of a
business, and any operational changes, business realignment projects or initiatives, restructurings or reorganizations that the Company or any Restricted Subsidiary has determined to make and/or made during the four-quarter reference period or
subsequent to such reference period and on or prior to or simultaneously with the Fixed Charge Calculation Date (each, for purposes of this definition, a “pro forma event”) shall be calculated on a pro forma basis assuming
that all such Investments, acquisitions, dispositions, mergers, amalgamations, consolidations, discontinued operations and other operational changes, business realignment projects or initiatives, restructurings or reorganizations (and the change of
any associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted
Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation, amalgamation, discontinued operation, operational
change, business realignment project or initiative, restructuring or reorganization, in each case with respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio
shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, discontinued operation, merger, amalgamation, consolidation, operational change, business realignment project or initiative,
restructuring or reorganization had occurred at the beginning of the applicable four-quarter period. If since the beginning of such period any Restricted Subsidiary is designated an Unrestricted Subsidiary or any Unrestricted Subsidiary is
designated a Restricted Subsidiary, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such designation had occurred at the beginning of the applicable four-quarter period. 

For purposes of this definition, whenever pro forma effect is to be given to any pro forma event, the pro forma
calculations shall be made in good faith by a responsible financial or accounting officer of the Company. Any such pro forma calculation may include adjustments appropriate, in the reasonable good faith determination of the Company as set
forth in an Officers’ Certificate, to reflect operating expense reductions and other operating improvements or synergies reasonably expected to result from the applicable event within 12 months of the date the applicable event is consummated;
provided that the aggregate amount of operating expense reductions and other operating improvements or synergies for the period for which the Fixed Charge Coverage Ratio is being calculated shall not exceed 20% of EBITDA for such period
(determined after giving effect to any such adjustments). 
 If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Fixed Charge 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 Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of
the Company to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a
pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar
rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate.

 For purposes of this definition, any amount in a currency other than U.S. dollars will be

period.

THE NOTES 
 SECTION 2.01
Amount of Notes. The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture on the Issue Date is $300,000,000. 

The Company may from time to time after the Issue Date issue Additional Notes under this Indenture in an unlimited principal amount, so long
as (i) the Incurrence of the Indebtedness represented by such Additional Notes is at such time permitted by Section 4.03 as evidenced in an Officers’ Certificate delivered to the Trustee and (ii) such Additional Notes are issued
in compliance with the other applicable provisions of this Indenture. With respect to any Additional Notes issued after the Issue Date (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of,
other Notes pursuant to Section 2.07, 2.08, 2.09, 3.08, 4.06(e), 4.08(c) or Appendix A), there shall be (a) established in or pursuant to a resolution of the Board of Directors of the Company and (b) (i) set forth or determined
in the manner provided in an Officers’ Certificate or (ii) established in one or more indentures supplemental hereto, prior to the issuance of such Additional Notes: 

(1) the aggregate principal amount of such Additional Notes which may be authenticated and delivered under this Indenture; 

(2) the issue price and issuance date of such Additional Notes, including the date from which interest on such Additional Notes
shall accrue; 
 (3) if applicable, that such Additional Notes shall be issuable in whole or in part in the form of one or
more Global Notes and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be borne by such Global Notes in addition to or in lieu of those set forth in Exhibit A hereto and any
circumstances in addition to or in lieu of those set forth in Section 2.2 of Appendix A in which any such Global Note may be exchanged in whole or in part for Additional Notes registered, or any transfer of such Global Note in whole or in part
may be registered, in the name or names of Persons other than the depositary for such Global Note or a nominee thereof; and 

(4) if applicable, that such Additional Notes that are not Transfer Restricted Notes shall not be issued in the form of Initial
Notes as set forth in Exhibit A hereto but shall be issued in the form of Exchange Notes as set forth in Exhibit B hereto. 

If any of the terms of any Additional Notes are established by action taken pursuant to a resolution of the Board of Directors, a copy of an
appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or an indenture supplemental hereto setting
forth the terms of the Additional Notes. 
 The Initial Notes and any Additional Notes may, at the Company’s option, be treated as a
single class of securities for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that if the Additional Notes are not fungible with the Initial Notes for U.S.
federal income tax purposes, the Additional Notes will have a separate CUSIP number, if applicable. 

  
 -37- 








 SECTION 2.02 Form and Dating. Provisions relating to the Initial Notes and the Exchange
Notes are set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Indenture. The (i) Initial Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes (if issued as
Transfer Restricted Notes) and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The (i) Exchange
Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes issued other than as Transfer Restricted Notes and the Trustee’s certificate of authentication shall each be substantially in the form set forth in
Exhibit B hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company or any Guarantor is
subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Note shall be dated the date of its authentication. The Notes shall be issuable only in registered form without
interest coupons and in denominations of $2,000 and any integral multiples of $1,000 in excess thereof, provided that Notes may be issued in denominations of less than $2,000 solely to accommodate book-entry positions that have been created by the
Depository in denominations of less than $2,000. 
 SECTION 2.03 Execution and Authentication. The Trustee shall authenticate and
make available for delivery upon a written order of the Company signed by one Officer of the Company (an “Authentication Order”) (a) Initial Notes for original issue on the date hereof in an aggregate principal amount of
$300,000,000, (b) subject to the terms of this Indenture, Additional Notes in an aggregate principal amount to be determined at the time of issuance and specified therein and (c) the Exchange Notes for issue in a Registered Exchange Offer
pursuant to the Registration Rights Agreement for a like principal amount of Initial Notes exchanged pursuant thereto or otherwise pursuant to an effective registration statement under the Securities Act. Such Authentication Order shall specify the
amount of separate Note certificates to be authenticated, the principal amount of each of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, whether the Notes are to be Initial Notes, Additional
Notes or Exchange Notes, the registered holder of each of the Notes and delivery instructions. Notwithstanding anything to the contrary in this Indenture or Appendix A, any issuance of Additional Notes after the Issue Date shall be in a principal
amount of at least $2,000 and integral multiples of $1,000 in excess thereof. 
 One Officer shall sign the Notes for the Company by manual
or PDF signature. 
 If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note,
the Note shall be valid nevertheless. 
 A Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent
as described immediately below) manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Company to authenticate the Notes. Any such appointment
shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.


  
 -38- 








 SECTION 2.04 Registrar and Paying Agent. 

(a) The Company shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (the
“Registrar”) and (ii) an office or agency where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may have
one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Company
initially appoints the Trustee as Registrar, Paying Agent and the Notes Custodian with respect to the Global Notes. 
 (b) The Company may
enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee in writing of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to
Section 7.07. The Company or any of its wholly owned domestically organized Subsidiaries may act as Paying Agent or Registrar. 
 (c)
The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of
an appointment by a successor Registrar or Paying Agent, as the case may be, as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or
(ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice
to the Company and the Trustee; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08. 

SECTION 2.05 Paying Agent to Hold Money in Trust. Prior to 10:00 a.m., New York City time, on each due date of the principal of and
interest on any Note, the Company shall deposit with each Paying Agent (or if the Company or any of its wholly owned domestically organized Subsidiaries 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 Notes, and shall notify the Trustee in writing of any default by the Company in making any such payment. If the Company or any of its wholly owned
domestically organized Subsidiaries 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. 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 Trustee shall preserve in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of holders. If the Trustee is not the Registrar, the Company shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such
other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of holders. 

  
 -39- 








 SECTION 2.07 Transfer and Exchange. The Notes shall be issued in registered
form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance with Appendix A. When a Note is presented to the Registrar with a request to register a transfer, the Registrar shall register the
transfer as requested if its requirements (including, among other things, the furnishing of appropriate endorsements and transfer documents) therefor are met. When Notes are presented to the Registrar with a request to exchange them for an equal
principal amount of Notes 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 Trustee shall authenticate
Notes 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. The Company shall not be
required to make, and the Registrar need not register, transfers or exchanges of any Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed) or of any Notes for a period of 15 days
before the mailing of a notice of redemption of Notes to be redeemed. 
 Prior to the due presentation for registration of transfer of any
Note, the Company, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest,
if any, on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 

Any holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial
interests in such Global Note may be effected only through a book-entry system maintained by (a) the holder of such Global Note (or its agent) or (b) any holder of a beneficial interest in such Global Note, and that ownership of a
beneficial interest in such Global Note shall be required to be reflected in a book entry. 
 All Notes 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 Notes surrendered upon such transfer or exchange. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depository participants or beneficial owners of interests in any Global Note) other than to require delivery of
such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof. 
 None of the Trustee, Registrar or Paying Agent shall have any responsibility for any actions taken or not taken by
the Depository. 
 SECTION 2.08 Replacement Notes. If a mutilated Note is surrendered to the Registrar or if the holder of a Note
claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the holder
(a) satisfies the Company and the Trustee within a reasonable time after such holder has notice of such loss, destruction or wrongful taking and the Registrar 

  
 -40- 








 
does not register a transfer prior to receiving such notification, (b) makes such request to the Company and the Trustee prior to the Note 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 Company and the Trustee. Such holder shall furnish an indemnity bond sufficient in the
judgment of the Trustee, with respect to the Trustee, and the Company, with respect to the Company, to protect the Company, the Trustee, the Paying Agent and the Registrar, as applicable, from any loss or liability that any of them may suffer if a
Note is replaced and subsequently presented or claimed for payment. The Company and the Trustee may charge the holder for their expenses in replacing a Note (including without limitation, attorneys’ fees and disbursements in replacing such
Note). In the event any such mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. 

Every replacement Note 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 Notes. 
 SECTION 2.09 Outstanding Notes. Notes
outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Subject to Section 11.06, a Note does not cease
to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant to Section 2.08
(other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be
outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.08. 
 If a Paying Agent segregates and holds in
trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (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 Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

 SECTION 2.10 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and each
Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation
and shall dispose of canceled Notes in accordance with its customary procedures. The Company may not issue new Notes to replace Notes they have redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Notes in
place of canceled Notes other than pursuant to the terms of this Indenture. 
 SECTION 2.11 Defaulted Interest. If the Company
defaults in a payment of interest on the Notes, the Company shall pay the defaulted interest then borne by the Notes (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 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. 

  
 -41- 








 SECTION 2.12 CUSIP Numbers, ISINs, Etc. The Company in issuing the Notes may use CUSIP
numbers, ISINs and “Common Code” numbers (if then generally in use), and the Trustee shall use any such 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 Notes or as contained in any notice of a redemption, that reliance may be placed only on the other
identification numbers printed on the Notes and that any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any such CUSIP numbers, ISINs and
“Common Code” numbers. 
 SECTION 2.13 Calculation of Principal Amount of Notes. The aggregate principal amount of the
Notes, at any date of determination, shall be the principal amount of the Notes at such date of determination. 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 Notes, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Notes, the holders of which have so consented, by (b) the
aggregate principal amount, as of such date of determination, of the Notes then outstanding, in each case, as determined in accordance with the preceding sentence, and Section 11.06 of this Indenture. Any calculation of the Applicable Premium
or Additional Interest made pursuant to this Indenture shall be made by the Company and delivered to the Trustee pursuant to an Officers’ Certificate. 

ARTICLE III 
 REDEMPTION

 SECTION 3.01 Redemption. The Notes may be redeemed, in whole or from time to time in part, subject to the conditions and at
the redemption prices set forth in Paragraph 5 of the forms of Notes set forth in Exhibits A and B hereto, which is hereby incorporated by reference and made a part of this Indenture, together with accrued and unpaid interest and
Additional Interest, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). 

SECTION 3.02 Applicability of Article. Redemption of Notes 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 III.

to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price. The Company shall give notice to the Trustee provided for in this paragraph at least 30
days but not more than 60 days before a redemption date if the redemption is a redemption pursuant to Paragraph 5 of the Notes. The Company may also include a request in such Officers’ Certificate that the Trustee give the notice of redemption
in the Company’s name and at its expense and setting forth the information to be stated in such notice as provided in Section 3.05. Any such notice may be canceled if written notice from the Company of such cancellation is actually
received by the Trustee on the Business Day immediately prior to notice of such redemption being mailed to any holder or otherwise delivered in accordance with the applicable procedures of the Depository and shall thereby be void and of no effect.
The Company shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 3.04. 

  
 -42- 








 SECTION 3.04 Selection of Notes to Be Redeemed. In the case of any partial redemption,
selection of the Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed (and the Company shall notify the Trustee of any such
listing), or if the Notes are not so listed, on a pro rata basis to the extent practicable or by lot or by such other method as the Trustee shall deem fair and appropriate (and, in such manner that complies with the requirements of the Depository,
if applicable); provided that no Notes of $2,000 (and integral multiples of $1,000 in excess thereof) or less shall be redeemed in part. The Trustee shall make the selection from outstanding Notes not previously called for redemption. The
Trustee may select for redemption portions of the principal of Notes that have denominations larger than $2,000. Notes and portions of them the Trustee selects shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof.
Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly of the Notes or portions of Notes to be redeemed. 

SECTION 3.05 Notice of Optional Redemption. 

(a) At least 30 but not more than 60 days before a redemption date pursuant to Paragraph 5 of the Notes, the Company shall mail or cause to be
mailed by first-class mail, or delivered electronically if the Notes are held by the Depository, a notice of redemption to each holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee), except that redemption
notices may be mailed or otherwise delivered more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article VIII. 

Any such notice shall identify the Notes to be redeemed and shall state: 

(i) the redemption date; 

(ii) the redemption price and the amount of accrued interest (including Additional Interest, if any) to, but excluding, the
redemption date; 
 (iii) the name and address of the Paying Agent; 

(iv) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price, plus accrued and
unpaid interest and Additional Interest, if any; 
 (v) if fewer than all the outstanding Notes are to be redeemed, the
certificate numbers and principal amounts of the particular Notes to be redeemed, the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption; 

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

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

  
 -43- 








 (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 Notes. 
 (b) At the
Company’s request, the Trustee shall deliver the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall notify the Trustee of such request at least seven (7) Business Days (or
such shorter period as is acceptable to the Trustee) prior to the date such notice is to be provided to holders. Such notice may not be canceled once delivered to holders of Notes. 

SECTION 3.06 Effect of Notice of Redemption. Once notice of redemption is mailed or otherwise delivered in accordance with
Section 3.05, Notes called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, except as provided in the final paragraph of paragraph 5 of the Notes. Upon surrender to the Paying Agent,
such Notes shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, the redemption date; provided, however, that if the redemption date is
after a regular Record Date and on or prior to the next Interest Payment Date, the accrued interest shall be payable to the holder of the redeemed Notes 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. 
 SECTION 3.07 Deposit of Redemption Price. With respect
to any Notes, 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 any of its wholly owned domestically organized Subsidiaries is the Paying Agent, shall segregate
and hold in trust) money sufficient to pay the redemption price of and accrued and unpaid interest and Additional Interest, if any, on all Notes or portions thereof to be redeemed on that date other than Notes or portions of Notes called for
redemption that have been delivered by the Company to the Trustee for cancellation. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the Company has deposited with the
Paying Agent funds sufficient to pay the redemption price of, plus accrued and unpaid interest and Additional Interest, if any, on, the Notes or portions thereof to be redeemed, unless the Paying Agent is prohibited from making such payment
pursuant to the terms of this Indenture. 
 SECTION 3.08 Notes Redeemed in Part. If any Note is to be redeemed in part only, the
notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. Upon surrender and cancellation of a Note that is redeemed in part, the Company shall execute and the Trustee shall authenticate for
the holder (at the Company’s expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered and cancelled. 

ARTICLE IV 
 COVENANTS

 SECTION 4.01 Payment of Notes. The Company shall promptly pay the principal of and interest on the Notes on the dates and in

 The Company shall pay interest on overdue principal at the rate specified therefor in the Notes,
and it shall pay interest on overdue installments of interest at the same rate borne by the Notes to the extent lawful. 
 SECTION 4.02
Reports and Other Information. 
 (a) Whether or not required by the rules and regulations the SEC, so long as any Notes are
outstanding, the Company will furnish to the holders (with a copy to the Trustee), within the time by which the Company would be required to file such information or reports with the SEC if it were subject to Section 13 or 15(d) of the Exchange
Act as a non-accelerated filer: 
 (i) all quarterly and annual information that would be required to be contained in reports
on Forms 10-Q and 10-K (or any successor or comparable form) required to be filed with the SEC if the Company were required to file such reports, including a “Management’s discussion and analysis of financial condition and results of
operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s independent registered public accounting firm; and 

(ii) all current reports that would be required to be filed with the SEC on Form 8-K (or any successor or comparable form) if
the Company were required to file such reports. 
 The financial information required by clause (i) of the immediately
preceding paragraph will be required to include a footnote presenting the condensed consolidating financial information specified in Rule 3-10(f)(4) of Regulation S-X promulgated by the SEC (or any successor provisions) and textual disclosure of
EBITDA if the non-Guarantors whose results are required to be consolidated for the purposes of presentation in accordance with GAAP of consolidated financial statements of the Company and its subsidiaries, if taken together as one subsidiary, would
constitute a Significant Subsidiary of the Company for any of the periods presented in such financial information. 
 (b) In the event that:

 (i) the rules and regulations of the SEC permit the Company and any direct or indirect parent of the Company to report at
such parent entity’s level on a consolidated basis and such parent entity 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 is or becomes a Guarantor of the Notes, 

consolidating reporting at the 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, and the Company is permitted to satisfy its obligations in this Section 4.02 with respect to financial information relating to the Company by furnishing financial information relating to such direct or indirect parent;
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, the Guarantors and the other Subsidiaries of the Company on a stand-alone basis, on the other hand. 

  
 -45- 








 (c) In addition, the Company shall, for so long as any Notes remain outstanding during any period
when it is not subject to Section 13 or 15(d) of the Exchange Act, or otherwise permitted to furnish the SEC with the information required by this covenant, furnish to the holders of the Notes, to bona fide prospective investors, market makers
affiliated with any initial purchaser of the Notes, and any bona fide securities analyst, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. The Company may satisfy its obligation to

affiliated with any initial purchaser of the Notes or bona fide securities analyst, in each case, who provides to the Company its email address, employer name and other information reasonably requested by the Company. For purposes of this covenant,
any prospective investor or securities analyst shall be deemed “bona fide” if it certifies it is “bona fide.”

Notwithstanding the foregoing, the Company will be deemed to have furnished the reports referred to in this Section 4.02 to the Trustee and the holders if the Company has filed such reports with the SEC via the EDGAR filing system (or successor
electronic filing system) and such reports are publicly available, it being understood that the Trustee shall have no responsibility to determine if such information is publicly available. 

(e) Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.02 is for informational purposes only,
and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under this

described in clauses (i) through (xxviii) of Section 4.03(b) above or is entitled to be Incurred pursuant to Section 4.03(a), then the Company may, in its sole discretion, classify or reclassify, and later divide, classify or
reclassify (as if Incurred at such later time), such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies with this Section 4.03; provided that Indebtedness outstanding under
the Credit Agreement on the Issue Date shall be deemed Incurred under clause (i) of Section 4.03(b) above. 
 Accrual of interest,

increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies will not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this
Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is 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. 

  
 -51- 








 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. However, if the Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign
currency, and the 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 the refinancing, the U.S. dollar-denominated restriction will
be deemed not to have been exceeded so long as the principal amount of the refinancing Indebtedness does not exceed the principal amount of the Indebtedness being refinanced. 

Notwithstanding any other provision of this Section 4.03, the maximum amount of Indebtedness that the Company and the Restricted
Subsidiaries may Incur pursuant to this Section 4.03 shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any
Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, will be calculated based on the currency exchange rate applicable to the currencies in which the respective
Indebtedness is denominated that is in effect on the date of the refinancing. 
 SECTION 4.04 Limitation on Restricted Payments. 

(a) The Company shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly:

Company or any of the Restricted Subsidiaries from the sale of Equity Interests (other than Disqualified Stock) of the Company or any direct or indirect parent of the Company (to the extent contributed to the Company) to employees, directors,

(xvi) the repurchase, redemption or other acquisition or retirement for value of any Subordinated Indebtedness pursuant to
provisions similar to those described in Section 4.06 and Section 4.08; provided that all Notes tendered by holders of the Notes in connection with a Change of Control Offer or Asset Sale Offer, as applicable, have been repurchased,

 (xvii) payments or distributions to dissenting stockholders pursuant to applicable law,
pursuant to or in connection with a consolidation, amalgamation, merger or transfer of all or substantially all of the assets of the Company and the Restricted Subsidiaries, taken as a whole, that complies with Section 5.01; provided
that as a result of such consolidation, amalgamation, merger or transfer of assets, the Company shall have made a Change of Control Offer (if required by this Indenture) and that all Notes tendered by holders in connection with such Change of
Control Offer have been repurchased, redeemed or acquired for value; 

  
 -56- 








 (xviii) any Restricted Payment constituting a redemption, purchase, repurchase,
defeasance or other acquisition or retirement of any Convertible Debentures or made in connection with the exercise of call options entered into in connection with the issuance of the Convertible Debentures; and

(x) $80.0 million and (y) the remaining net proceeds from the issuances of the notes on the Issue Date after giving effect to the use of proceeds therefrom as described in the Offering Memorandum; 

provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under clauses (vi)(B), (vii), (x), (xii)(B)
and (xix) of this Section 4.04(b), no Default shall have occurred and be continuing or would occur as a consequence thereof; provided, further, that any Restricted Payments made with property other than cash shall be
calculated using the Fair Market Value (as determined in good faith by the Company) of such property. 
 For purposes of determining
compliance with this covenant, (a) in the event that a proposed Restricted Payment or any Investment (or any portion thereof) meets the criteria of more than one of the categories of Restricted Payments described in clauses (i) through
(xix) above or is entitled to be made pursuant to Section 4.04(a), or in the event that any Permitted Investment meets the criteria of more than one of the clauses of such term, then the Company may, in its sole discretion, classify or
reclassify, or later divide, classify or reclassify (as if made at such later time), such Restricted Payment or any Investment (or any portion thereof) in any manner that complies with this Section 4.04 or the definition of “Permitted
Investments.” 
 (c) As of the Issue Date, all of the Subsidiaries of the Company, other than the GST Group, will be Restricted
Subsidiaries. The Company will 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 the Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the
last sentence of the definition of “Investments.” Such designation will 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 Restricted Subsidiary 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 the Company or any Restricted
Subsidiary to: 
 (a) pay dividends or make any other distributions to the Company or any Restricted Subsidiary (1) on
its Capital Stock; or (2) with respect to any other interest or participation in, or measured by, its profits; or 
 (b)
make loans or advances to the Company or any Restricted Subsidiary that is a direct or indirect parent of such Restricted Subsidiary; 
 except in
each case for such encumbrances or restrictions existing under or by reason of: 
 (1) (i) contractual encumbrances or
restrictions in effect on the Issue Date and (ii) contractual encumbrances or restrictions pursuant to the Credit Agreement and 

  
 -57- 








 
the other Credit Agreement Documents and, in each case, any similar contractual encumbrances effected by any amendments, modifications, restatements, renewals, supplements, refundings,
replacements or refinancings of such agreements or instruments; 
 (2) this Indenture, the Notes or the Guarantees (including
any Exchange Notes and related guarantees); 
 (3) applicable law or any applicable rule, regulation or order; 

(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 or to provide all or any portion of the funds or credit support utilized to consummate such acquisition), which encumbrance or restriction is not applicable to any Person, or
the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired; 

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

(6) Secured Indebtedness otherwise permitted to be Incurred pursuant to Section 4.03 and Section 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, partnership agreements, limited liability company agreements and similar agreements required in connection with the entering into of such transaction; 

(9) purchase money obligations for property acquired in the ordinary course of business and Capitalized Lease Obligations
otherwise not prohibited under this Indenture; 
 (10) customary provisions contained in leases, licenses and other similar
agreements entered into in the ordinary course of business; 
 (11) any encumbrance or restriction that restricts in a
customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease, license or similar contract, or the assignment or transfer of any such lease, license (including without limitations, licenses of
intellectual property) or other contracts; 
 (12) any encumbrance or restriction of a Securitization Subsidiary effected in
connection with a Qualified Securitization Financing; provided, however, that such restrictions apply only to such Securitization Subsidiary; 

(13) other Indebtedness, Disqualified Stock or Preferred Stock (a) of the Company or any Restricted Subsidiary that is a
Guarantor or a Foreign Subsidiary or (b) of any Restricted Subsidiary that is not a Guarantor or a Foreign Subsidiary so long as 

  
 -58- 








 
such encumbrances and restrictions contained in any agreement or instrument will not materially affect the Company’s ability to make anticipated principal or interest payments on the Notes
(as determined in good faith by the Company), provided that in the case of each of clauses (a) and (b), such Indebtedness, Disqualified Stock or Preferred Stock is permitted to be Incurred subsequent to the Issue Date pursuant to
Section 4.03; 
 (14) any Restricted Investment not prohibited by Section 4.04 and any Permitted Investment; or

 (15) any encumbrances or restrictions of the type referred to in Section 4.05(a) or (b) 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, taken 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 common stock 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 the Restricted Subsidiaries to, cause or make an Asset Sale, unless (x) the Company
or any 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, and (y) 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 a Restricted Subsidiary’s most recent balance sheet or in the notes
thereto) of the Company or a Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed by the transferee of any such assets or that are otherwise cancelled or terminated in
connection with the transaction with such transferee, 
 (ii) any notes or other obligations or other securities or assets
received by the Company or such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received), 

(iii) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to
the extent that the Company and each other Restricted Subsidiary are released from any guarantee of payment of such Indebtedness in connection with the Asset Sale, 

  
 -59- 








 (iv) consideration consisting of Indebtedness of the Company (other than
Subordinated Indebtedness) received after the Issue Date from Persons who are not the Company or any Restricted Subsidiary, and 

(v) any Designated Non-cash Consideration received by the Company or any Restricted Subsidiary in such Asset Sale having an
aggregate Fair Market Value (as determined in good faith by the Company), taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.06(a)(v) that is at that time outstanding, not to exceed $75.0 million
(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 be deemed to be Cash Equivalents for the purposes of this Section 4.06(a). 

(b) Within 365 days after the Company’s or any Restricted Subsidiary’s receipt of the Net Proceeds of any Asset Sale, the Company or
such Restricted Subsidiary may apply the Net Proceeds from such Asset Sale, at its option: 
 (i) to repay, prepay, purchase,
redeem, acquire or otherwise reduce (A) Indebtedness constituting Credit Facility Indebtedness and other Pari Passu Indebtedness that is secured by a Lien permitted under this Indenture (and, if the Indebtedness repaid is revolving credit
Indebtedness, to correspondingly reduce commitments with respect thereto), (B) Indebtedness of a Restricted Subsidiary that is not a Guarantor, (C) Obligations under the Notes or (D) other Pari Passu Indebtedness (provided that
if the Company or any Guarantor shall so reduce the Obligations under unsecured Pari Passu Indebtedness under this clause (D), the Company will equally and ratably reduce Notes Obligations pursuant to Section 3.01, through open-market purchases
(provided that such purchases are at or above 100% of the principal amount thereof or, in the event that the Notes were issued with significant original issue discount, 100% of the accreted value thereof) or by 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 (or, in the event that the Notes were issued with significant original issue discount, 100% of
the accreted value thereof), plus accrued and unpaid interest and Additional Interest, if any, on the pro rata principal amount of Notes), in each case other than Indebtedness owed to the Company or an Affiliate of the Company; or 

(ii) to invest in Replacement Assets or to reimburse the cost of any investment in Replacement Assets incurred on or after the
date on which the Asset Sale giving rise to such Net Proceeds was contractually committed. 
 In the case of Section 4.06(b)(ii), a
binding commitment entered into not later than such 365th day shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as the Company or such Restricted Subsidiary enters into such commitment with the
good faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment; provided that in the event such binding commitment is later canceled or terminated for any reason before such Net
Proceeds are so applied, then such Net Proceeds shall constitute Excess Proceeds. 
 Pending the final application of any such Net Proceeds,
the Company or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture. Any Net Proceeds from any Asset Sale that
are not applied as provided and within the time period set forth in the first sentence of this Section 4.06(b) (it being understood that any portion of such Net Proceeds used to make an offer to purchase Notes, as described in clause
(i) of this Section 4.06(b), shall be deemed to have been invested whether or not such 

  
 -60- 








 
offer is accepted) will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $75.0 million, the Company shall make an offer to all
holders of Notes (and, at the option of the Company, to holders of any other Pari Passu Indebtedness) (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes (and such other Pari Passu Indebtedness), that is at
least $2,000 and an integral multiple of $1,000 in excess thereof 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, in the event the Notes or other Pari Passu
Indebtedness were issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest and Additional Interest, if any (or, in respect of such other Pari Passu Indebtedness, such lesser price,
if any, as may be provided for by the terms of such other Pari Passu Indebtedness), to, but excluding, the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Company will commence an Asset
Sale Offer with respect to Excess Proceeds within ten (10) Business Days after the date that Excess Proceeds exceeds $75.0 million by mailing, or delivering electronically if the Notes are held by the Depository, the notice required pursuant to
the terms of this Indenture, with a copy to the Trustee. To the extent that the aggregate amount of Notes (and such other Pari Passu Indebtedness) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for any purpose that is not prohibited by this Indenture. If the aggregate principal amount of Notes (and such other Pari Passu Indebtedness) surrendered by holders thereof exceeds the amount of Excess Proceeds, the
Trustee, upon receipt of notice from the Company of the aggregate principal amount to be selected, shall select the Notes 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 will 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 Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Indenture, the Company will 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 as provided above, the Company shall
deliver to the Trustee an Officers’ Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the
compliance of such allocation with the provisions of Section 4.06(b). 
 (e) Holders electing to have a Note purchased shall be
required to surrender such Note, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the
Trustee or the Company receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered by the holder
for purchase and a statement that such holder is withdrawing his election to have such Note purchased. If at the expiration of the period for which the Asset Sale Offer remains open more Notes (and such other Pari Passu Indebtedness) are tendered
pursuant to an Asset Sale Offer than the Company is required to purchase, selection of such Notes for purchase shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such
Notes are listed (and the Company shall notify the Trustee of any such listing), or if such Notes are not so listed, on a pro rata basis to the extent practicable, by lot or by such other method as the Trustee shall deem fair and appropriate (and in
such manner as complies with the requirements of the Depository, if applicable); provided that no Notes of $2,000 or less shall be purchased in part. Selection of such other Pari Passu Indebtedness shall be made pursuant to the terms of such
other Pari Passu Indebtedness. 

  
 -61- 








 (f) Notices of an Asset Sale Offer shall be mailed by the Company by first class mail, postage
prepaid, or delivered electronically if held by the Depository, at least 30 but not more than 60 days before the purchase date to each holder of Notes at such holder’s registered address. If any Note is to be purchased in part only, any notice
of purchase that relates to such Note shall state the portion of the principal amount thereof that has been or is to be purchased. 

SECTION 4.07 Transactions with Affiliates. 

(a) The Company shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, make any payment to, or sell,
lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of transactions, contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $25.0 million, unless: 

(i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 

(ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $75.0 million, the Company delivers to the Trustee a resolution adopted in good faith by the majority of the Board of Directors of the Company, approving such Affiliate Transaction and set forth in an Officers’ Certificate certifying
that such Affiliate Transaction complies with clause (i) above. 
 (b) The provisions of Section 4.07(a) shall not apply to the
following: 
 (i) transactions between or among the Company and/or any of the Restricted Subsidiaries (or an entity that
becomes a Restricted Subsidiary as a result of such transaction) and any merger, consolidation or amalgamation of the Company and any direct parent of the Company; provided that such parent shall have no material liabilities and no material
assets other than cash, Cash Equivalents and the Capital Stock of the Company and such merger, consolidation or amalgamation is otherwise in compliance with the terms of this Indenture and effected for a bona fide business purpose; 

(ii) Restricted Payments permitted by Section 4.04 and Permitted Investments; 

(iii) the payment of reasonable and customary fees and reimbursement of expenses paid to, and indemnity provided on behalf of,
officers, directors, employees or consultants of the Company, any Restricted Subsidiary, or any direct or indirect parent of the Company; 

(iv) transactions in which the Company or any Restricted Subsidiary, as the case may be, delivers to the Trustee a letter from
an Independent Financial Advisor stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or meets the requirements of clause (i) of Section 4.07(a); 

  
 -62- 








 (v) payments or loans (or cancellation of loans) to officers, directors,
employees or consultants which are approved by a majority of the Board of Directors of the Company in good faith; 
 (vi) any
agreement as in effect as of the Issue Date or any amendment thereto or renewal, extension, restatement or replacement thereof (so long as any such agreement together with all amendments thereto and renewals, extensions, restatements and
replacements thereof, taken as a whole, is not more disadvantageous to the holders of the Notes in any material respect than the original agreement as in effect on the Issue Date) or any transaction contemplated thereby as determined in good faith
by the Company; 
 (vii) the existence of, or the performance by the Company or any Restricted Subsidiary of its obligations
under the terms of any stockholders or limited liability company agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date, and any transaction, agreement or arrangement
described in the Offering Memorandum and, in each case, any amendment thereto or similar transactions, agreements or arrangements which it may enter into thereafter; provided, however, that the existence of, or the performance by the
Company or any Restricted Subsidiary of its obligations under, any future amendment to any such existing transaction, agreement or arrangement or under any similar transaction, agreement or arrangement entered into after the Issue Date shall only be
permitted by this clause (vii) to the extent that the terms of any such existing transaction, agreement or arrangement together with all amendments thereto, taken as a whole, or new transaction, agreement or arrangement are not otherwise more
disadvantageous to the holders of the Notes in any material respect than the original transaction, agreement or arrangement as in effect on the Issue Date; 

(viii) the execution of the Transactions, and the payment of all costs, fees and expenses related to the Transactions; 

(ix) (A) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, or transactions
otherwise relating to the purchase or sale of goods or services, 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 the Restricted Subsidiaries in the
reasonable determination of the Board of Directors or the senior management of the Company, or are on terms at least as favorable in all material respects 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 and consistent with past practice or industry norm; 

(x) any transaction effected as part of a Qualified Securitization Financing; 

(xi) the issuance of Equity Interests (other than Disqualified Stock) of the Company to any Person; 

(xii) the issuances of securities or other payments, awards or grants in cash, securities or otherwise pursuant to, the funding
of, or the making of payments pursuant to, employment, consulting and service agreements and arrangements, stock option and stock ownership plans, long-term incentive plans or similar employee or director benefit plans approved by the Board of
Directors of the Company or any direct or indirect parent of the Company or the Board of Directors of a Restricted Subsidiary, as appropriate, in good faith;

 (xiv) transactions permitted by, and complying with, Section 5.01; 

(xv) transactions between the Company or any Restricted Subsidiary and any Person, a director of which is also a director of

forth in this Indenture; and 
 (xx) transactions with any entity included in the GST Group (including intercompany service

 SECTION 4.08 Change of Control. 

(a) Upon the occurrence of a Change of Control, each holder shall have the right to require the Company to repurchase all or any part of such
holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, 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 of a Change
of Control, the Company shall not be obligated to purchase any Notes pursuant to this Section 4.08 in the event that it has previously or concurrently exercised its right to redeem such Notes in accordance with Article III of this Indenture. In
the event that at the time of such Change of Control, the terms of the Credit Facility Indebtedness restrict or prohibit the repurchase of Notes pursuant to this Section 4.08, then prior to the mailing of the notice to the holders provided for
in Section 4.08(b) but in any event within 60 days following any Change of Control, the Company shall: (i) repay in full all Credit Facility Indebtedness or, if doing so will allow the purchase of Notes, offer to repay in full all Credit
Facility Indebtedness and repay the Credit Facility Indebtedness of each lender and/or noteholder who has accepted such offer; or (ii) obtain the requisite consent under the agreements governing the Credit Facility Indebtedness to permit the
repurchase of the Notes as provided for in Section 4.08(b). 
 (b) Within 30 days following any Change of Control, except to the extent
that the Company has exercised its right to redeem the Notes in accordance with Article III of this Indenture, the Company shall mail, or deliver electronically if the Notes are held by DTC, a notice (a “Change of Control Offer”) to
each holder with a copy to the Trustee stating: 
 (i) that a Change of Control has occurred and that such holder has the
right to require the Company to repurchase such holder’s Notes at a repurchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, the date of
repurchase (subject to the right of the holders of record on the relevant Record Date to receive interest on the relevant Interest Payment Date); 

  
 -64- 








 (ii) the transaction or transactions constituting such Change of Control; 

(iii) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed);
and 
 (iv) the instructions determined by the Company, consistent with this Section 4.08, that a holder must follow in
order to have its Notes purchased. 
 (c) Holders electing to have a Note purchased shall be required to surrender the Note, with an
appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. The holders shall be entitled to withdraw their election if the Trustee or the Company receives not later
than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered for purchase by the holder and a statement that such
holder is withdrawing its election to have such Note purchased. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered. 

(d) On the purchase date, all Notes purchased by the Company under this Section 4.08 shall be delivered to the Trustee for cancellation,
and the Company shall pay the purchase price plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, the date of repurchase, to the holders entitled thereto. 

(e) 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 of the Change of Control Offer. 
 (f) Notwithstanding the foregoing
provisions of this Section 4.08, the Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer. 

(g) Notes repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be
retired and canceled at the option of the Company. Notes purchased by a third party pursuant to clause (f) or clause (k) of this Section 4.08 will have the status of Notes issued and outstanding. 

(h) At the time the Company delivers Notes to the Trustee which are to be accepted for purchase, the Company shall also deliver an
Officers’ Certificate stating that such Notes are to be accepted by the Company pursuant to and in accordance with the terms of this Section 4.08. 

A Note shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment
therefor to the surrendering holder. 
 (i) 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 Notes pursuant to this Section. To the extent that the provisions of any securities laws or regulations conflict with provisions of this
Section 4.08, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section by virtue thereof. 

  
 -65- 








 (j) If holders of not less than 90% in aggregate principal amount of the outstanding Notes
validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn
by such holders, the Company or such third party will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all Notes
that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to, but excluding, the date of redemption. Any such redemption shall be effected pursuant to Article
III. 
 SECTION 4.09 Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal
year of the Company, beginning with the fiscal year ending on December 31, 2014, an Officers’ Certificate stating that in the course of the performance by the signers (one of which shall be the principal executive officer, the principal
financial officer or principal accounting officer of the Company) of their duties as Officers of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. If
any Officer does, the certificate shall describe the Default, its status and what action the Company is taking or proposes to take with respect thereto. In addition, so long as any Notes are outstanding, if any Default has occurred and is continuing
under this Indenture, the Company shall within 30 Business Days of the occurrence thereof deliver to the Trustee an Officers’ Certificate specifying such Default and what action the Company is taking or proposed to take with respect thereto.
The Company also shall comply with Section 314(a)(4) of the TIA. Except with respect to receipt of payments of principal and interest on the Notes and any Default or Event of Default information contained in an Officers’ Certificate
delivered to it pursuant to this Section 4.09, the Trustee shall have no duty to review, ascertain or confirm the Company’s compliance with or the breach of any representation, warranty or covenant made in this Indenture. 

SECTION 4.10 Further Instruments and Acts. Upon request of the Trustee, the Company 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. 
 SECTION
4.11 Future Guarantors. The Company shall cause each of its Wholly Owned Domestic Subsidiaries that guarantees or becomes a borrower under the Credit Agreement or that guarantees any other Capital Markets Indebtedness of the Company or any of
the Guarantors (in each case, other than the GST Group, as to which the following sentence applies) to execute and deliver to the Trustee, within 10 Business Days thereafter, a supplemental indenture substantially in the form of Exhibit D
pursuant to which such Subsidiary will guarantee the Guaranteed Obligations. An Event of Default under the Notes shall occur if any member of the GST Group guarantees or becomes a borrower under the Credit Agreement or guarantees any other Capital
Markets Indebtedness of the Company or any of the Guarantors and fails, within the time period specified in Section 6.01(j), to execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit D pursuant
to which such Subsidiary will guarantee the Guaranteed Obligations. 
 SECTION 4.12 Liens. 

(a) The Company shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist
any Lien (except Permitted Liens) on any asset or property of the Company or such Restricted Subsidiary securing Indebtedness of the Company or a Restricted 

  
 -66- 








 
Subsidiary unless the Notes are equally and ratably secured with (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes) the obligations so secured
until such time as such obligations are no longer secured by a Lien. 
 (b) Any Lien that is granted to secure the Notes or any 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 Notes or such Guarantee under Section 4.12(a). 

(c) For purposes of determining compliance with this Section 4.12, (i) a Lien securing an item of Indebtedness need not be permitted
solely by reference to one category of permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to Section 4.12(a) but may be permitted in part under any combination thereof and
(ii) in the event that a Lien securing an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of one or more of the categories of permitted Liens (or any portion thereof) described in the
definition of “Permitted Liens” or pursuant to Section 4.12(a), the Company may, in its sole discretion, classify or reclassify, or later divide, classify or reclassify (as if Incurred at such later time), such Lien securing such item
of Indebtedness (or any portion thereof) in any manner that complies with this covenant and will be entitled to only include the amount and type of such Lien or such item of Indebtedness secured by such Lien (or any portion thereof) in one of the
categories of permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to Section 4.12(a) and, in such event, such Lien securing such item of Indebtedness (or any portion thereof) will be
treated as being Incurred or existing pursuant to only such clause or clauses (or any portion thereof) or pursuant to Section 4.12(a) without giving pro forma effect to such item (or portion thereof) when calculating the amount of Liens
or Indebtedness that may be Incurred pursuant to any other clause or paragraph. 
 (d) With respect to any Lien securing Indebtedness that
was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall
mean any increase in the amount of such Indebtedness in connection with any 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 or in the form of common stock of the Company, the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class, accretion of original issue discount or liquidation preference and increases
in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness described in clause (3) of the definition of “Indebtedness.”

 SECTION 4.13 Maintenance of Office or Agency. 

(a) The Company shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or Registrar) where
Notes may be surrendered for registration of transfer or for exchange. 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 and surrenders may be made at the Corporate Trust Office of the Trustee as set forth in Section 11.02. 

(b) The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such
purposes. 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. 

  
 -67- 








 (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 Existence. The Company shall do or cause to be
done all things necessary to preserve, renew and keep in full force and effect its legal existence and the rights, licenses, permits, privileges and franchises material to the conduct of its business; provided that the foregoing shall not
prohibit any transaction permitted under Section 5.01, and the Company shall not be required to preserve, renew and keep in full force and effect any such right, license, permit, privilege, franchise or legal existence if the Company shall
determine in good faith the preservation, renewal or keeping in full force and effect thereof is no longer desirable in the conduct of the business of the Company. 

SECTION 4.15 Covenant Suspension. If on any date following the Issue Date, (i) the Notes have Investment Grade Ratings from both
Rating Agencies, and (ii) no Default has occurred and is continuing under this Indenture, then, beginning on that day (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a
“Covenant Suspension Event”), and subject to the provisions of the following paragraph, the Company and the Restricted Subsidiaries shall not be subject to Sections 4.03, 4.04, 4.05, 4.06, 4.07, 4.11 and 5.01(a)(iv) (collectively
the “Suspended Covenants”). 
 In the event that the Company and the Restricted Subsidiaries are not subject to the
Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade
the rating assigned to the Notes below an Investment Grade Rating, then the Company and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. 

The Company shall provide the Trustee with notice of each Covenant Suspension Event or Reversion Date within 5 Business Days of the occurrence
thereof. 
 During the Suspension Period, the Company may not designate or redesignate any Unrestricted Subsidiaries. 

On each Reversion Date, all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be
classified as having been Incurred or issued pursuant to Sections 4.03(a) and (b) (to the extent such Indebtedness or Disqualified Stock or Preferred Stock would be permitted to be Incurred or issued thereunder as of the Reversion Date and
after giving effect to Indebtedness Incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Stock or Preferred Stock would not be so permitted to be Incurred or issued
pursuant to Sections 4.03(a) and (b), such Indebtedness or Disqualified Stock or Preferred Stock will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(iii). Calculations made
after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.04 will be made as though Section 4.04 had been in effect since the Issue Date and prior to, but not during, the Suspension Period.
Accordingly, Restricted Payments made during the Suspension Period will not reduce the amount available to be made as Restricted Payments under Section 4.04(a). As described above, however, no Default or Event of Default will be deemed to have
occurred on the Reversion Date as a result of any actions taken by the Company or the Restricted Subsidiaries during the Suspension Period or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date,
regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. Within 30 days of such Reversion Date, the Company must comply with the terms of Section 4.11.


  
 -68- 








 For purposes of Section 4.05, on the Reversion Date, any consensual encumbrances or
consensual restrictions of the type specified in clause (a) or (b) thereof entered into during the Suspension Period will be deemed to have been in effect on the Issue Date, so that they are permitted under clause (1)(i) thereof. 

For purposes of Section 4.07, any Affiliate Transaction entered into after the Reversion Date pursuant to a contract, agreement, loan,
advance or guaranty with, or for the benefit of, any Affiliate of the Company entered into during the Suspension Period will be deemed to have been in effect as of the Issue Date for purposes of clause (b)(vi) thereof. 

For purposes of Section 4.06, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero.

Indebtedness which becomes an obligation of the Successor Company or any of its Restricted Subsidiaries as a result of such transaction as having been Incurred by the Successor Company or such Restricted Subsidiary at the time of such transaction)
no Default shall have occurred and be continuing; 
 (iv) immediately after giving pro forma effect to such

additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.03(a); or 
 (2) the

Restricted Subsidiary may merge, consolidate or amalgamate with or transfer all or part of its properties and assets to a Restricted Subsidiary or, provided that the Company is the Successor Company, the Company, and (B) the Company may merge,
consolidate or amalgamate with an Affiliate incorporated solely for the purpose of reincorporating the Company in another state of the United States, the District of Columbia or any territory of the United States (collectively, “Permitted
Jurisdictions”) or may convert into a corporation, partnership or limited liability company, so long as the amount of Indebtedness of the Company and the Restricted Subsidiaries is not increased thereby. This Section 5.01(a) will not
apply to a sale, assignment, transfer, lease, conveyance or other disposition of assets between or among the Company and the Restricted Subsidiaries. 

(b) Subject to the provisions of Section 10.02(b), no Guarantor shall, and the Company shall not permit any such Guarantor to,

more related transactions to, any Person unless:

Section 4.06; and 
 (ii) the Successor Guarantor (if other than such Guarantor) shall have delivered or caused to be
delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger or transfer and such supplemental indenture (if any) comply with this Indenture. 

  
 -70- 








 Except as otherwise provided in this Indenture, the Successor Guarantor (if other than such
Guarantor) will succeed to, and be substituted for, such Guarantor under this Indenture and the Notes or the Guarantee, as applicable, and such Guarantor will automatically be released and discharged from its obligations under this Indenture and the
Notes or its Guarantee. Notwithstanding the foregoing, (1) a Guarantor may merge, amalgamate or consolidate with an Affiliate incorporated solely for the purpose of reincorporating such Guarantor in a Permitted Jurisdiction or may convert into
a limited liability company, corporation, partnership or similar entity organized or existing under the laws of any Permitted Jurisdiction so long as the amount of Indebtedness of such Guarantor is not increased thereby and (2) a Guarantor may
consolidate, amalgamate or merge with or into or wind up into, liquidate, dissolve, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets to the Company or any Guarantor.

than a default referred to in clauses (a), (b) and (c) above) contained in the Notes or this Indenture; 
 (e)
there is a failure by the Company or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay any Indebtedness (other than Indebtedness owing to the Company or a Restricted Subsidiary)
within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $100.0 million or
its foreign currency equivalent, but (for the avoidance of doubt), in each case, excluding any failure to make a payment on, or otherwise comply with, the terms of either of the GST Group Intercompany Notes or the Coltec/Stemco Subordinated Guaranty
to the extent such payment or compliance is prohibited by a GST Group Subordination Agreement; 

  
 -71- 








 (f) the Company or any Significant Subsidiary (or any group of Subsidiaries that
together would constitute a Significant Subsidiary) 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 comparable action under any foreign laws relating

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

the Trustee). 

  
 -72- 








 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. 

However, a default under clause (c) or (d) above shall not constitute an Event of Default until the Trustee or the holders of at
least 25% in principal amount of outstanding Notes notify the Company, with a copy to the Trustee, of the default and the Company does not cure such default within the time specified in clauses (c) or (d) hereof 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 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. 

SECTION 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(f) or (g) hereof
with respect to the Company) occurs and is continuing, the Trustee by notice to the Company or the holders of at least 25% in principal amount of outstanding Notes by notice to the Company, with a copy to the Trustee, may declare the principal of,
premium, if any, and accrued but unpaid interest on all the Notes 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(f) or
(g) with respect to the Company occurs, the principal of, premium, if any, and interest on all the Notes will become 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 outstanding Notes by notice to the Trustee may rescind any such acceleration with respect to the Notes 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 or other Default or impair any consequent right. 

In the event of any Event of Default specified in Section 6.01(e), such Event of Default and all consequences thereof (excluding,
however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the holders of the Notes, if within 30 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 Notes 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 Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee 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. To the extent required by law, all available remedies are cumulative. 

  
 -73- 








 SECTION 6.04 Waiver of Past Defaults. Provided the Notes are not then due and payable by
reason of a declaration of acceleration, the holders of a majority in principal amount of the Notes then outstanding by written notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the
principal of or interest on a Note, (b) a Default arising from the failure to redeem or purchase any Note when required pursuant to the terms of this Indenture or (c) a 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, it is deemed cured and the Company, the Trustee and the holders will be restored to their former positions and rights under 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. The holders of a
majority in principal amount of outstanding Notes 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, if the Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine
that the action or proceeding so directed would involve the Trustee in personal liability or expense for which it is not adequately indemnified, 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. 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. 
 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 Notes unless: 
 (i) such holder has previously given the Trustee written notice that an
Event of Default is continuing, 
 (ii) holders of at least 25% in principal amount of the outstanding Notes have requested
the Trustee to pursue the remedy, 
 (iii) such holders have offered the Trustee security or indemnity satisfactory to it
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 Notes have not given the Trustee a direction inconsistent with such request within 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 (it being understood that the Trustee shall have no obligation to ascertain whether or not such actions or forbearances are
unduly prejudicial to any other 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 Notes held by such holder, on or after the respective due dates expressed or provided for in the Notes, 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. 

  
 -74- 








 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 Notes 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 Notes) 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, statements of interest 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 necessary, advisable or appropriate)) and the holders allowed in any judicial proceedings relative to the Company, the Guarantors, 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 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. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any holder, or to authorize the Trustee to
vote in respect of the claim of any holder in any such proceeding. 
 SECTION 6.10 Priorities. Any money or property collected by the
Trustee pursuant to this Article VI and any other money or property distributable in respect of the Company’s or any Guarantor’s obligations under this Indenture after an Event of Default shall be applied in the following order: 

FIRST: to the Trustee for amounts due hereunder (including the reasonable compensation and expenses, disbursements and advances
of the Trustee’s agents, counsel, accountants and experts in accordance with Section 7.07); 
 SECOND: to the
holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal 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 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 mail to each holder and the Company a notice that states the record date, the payment date and the amount to be paid.

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.

(a) The Trustee, prior to the occurrence of an Event of Default with respect to the Notes and after the curing or waiving of all Events of
Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested

implied covenants or obligations shall be read into this Indenture against the Trustee (it being agreed that the permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty); 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. The Trustee shall be under no duty to make any investigation as to any statement contained in
any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. However, in the case of certificates or opinions required by any provision hereof to be provided to
it, the Trustee shall examine the form of certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated
therein). 
 (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own
willful misconduct, except that: 
 (i) this paragraph does not limit the effect of paragraph (b) of this Section; 

(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; and

this Indenture and the Notes 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.

adequacy of this Indenture, the Guarantees or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes, 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 Notes or in the Notes 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(b)(but
only with respect to a repurchase of Notes pursuant to an Asset Sale Offer), (c), (d), (e), (f), (g), (h), (i) or (j), or of the identity of any Significant Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof

 -78- 








 SECTION 7.05 Notice of Defaults. If a Default occurs and is continuing and is actually
known to a Trust Officer or the Trustee, the Trustee shall mail, or deliver electronically if the Notes are held by DTC, to each holder of the Notes 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 Note, the Trustee may withhold notice if and so long as it in good faith
determines that withholding notice is in the interests of the noteholders. 
 SECTION 7.06 Reports by Trustee to the Holders. As
promptly as practicable after each May 15th beginning with the May 15th following the date of this Indenture, and in any event within
60 days of each May 15th, the Trustee shall mail to each holder a brief report dated as of such May 15th that complies with
Section 313(a) of the TIA if and to the extent required thereby. The Trustee shall also comply with Section 313(b) of the TIA. 

Pursuant to Section 313(d) of the TIA, a copy of each report at the time of its mailing to the holders shall be filed with the SEC and
each stock exchange (if any) on which the Notes are listed if the Notes are listed. The Company agrees to notify promptly the Trustee whenever the Notes become listed on any stock exchange and of any delisting thereof. All reports pursuant to this
Section 7.06 shall be provided in accordance with Section 313(c) of the TIA. 
 SECTION 7.07 Compensation and Indemnity.
The Company shall pay to the Trustee from time to time such compensation for the Trustee’s acceptance of this Indenture and its services hereunder as mutually agreed to in writing between the Company and the Trustee. The Trustee’s
compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company and the Guarantors, jointly
and severally, shall indemnify the Trustee or any predecessor Trustee and their directors, officers, employees and agents against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses and
including taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) 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 any 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 obligation to pay such amounts shall survive the payment in full or defeasance of the Notes or the removal or resignation of the Trustee. 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 such Guarantor, 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 actual or
potential 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. 

  
 -79- 








 To secure the Company’s and the Guarantors’ payment obligations in this
Section 7.07, the Trustee shall have a Lien prior to the Notes 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 Notes. 

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(f) or (g) with respect to the Company, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. 

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction. 

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 Notes may remove the
Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall 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. 

(b) If the Trustee resigns, is removed by the Company or by the holders of a majority in principal amount of the Notes 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 Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee. 

(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 Note 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. 

  
 -80- 








 (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 or
banking association without any further act shall be the successor Trustee. 
 In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any
predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in
the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 7.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section 310(a) of the TIA.
The Trustee shall have a combined capital and surplus of at least $50.0 million 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 the 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.

Trustee on or prior to the date of the redemption; 
 (ii) the Company and/or the Guarantors have paid all other sums payable

 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 Trustee cash in U.S. dollars, U.S. Government Obligations or a
combination thereof sufficient to pay the principal of and premium (if any) and interest on the Notes when due at maturity or redemption, as the case may be;

delivers to the Trustee a certificate from a nationally recognized firm of independent accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm, expressing their opinion that the payments of
principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal,
premium, if any, and interest when due on all the Notes to maturity or redemption, as the case may be; provided that upon any redemption that requires the payment of the Applicable Premium, the amount deposited shall be sufficient for
purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to the Applicable Premium calculated as of the date of the notice of redemption, with any deficit as of the date of the redemption only required to be
deposited with the Trustee on or prior to the date of the redemption; 
 (iii) no Default specified in Section 6.01(f)
or (g) with respect to the Company shall have occurred or is continuing on the date of such deposit; 
 (iv) the deposit
does not constitute a default under any other material agreement or instrument binding on the Company; 
 (v) the Company
shall have delivered to the Trustee in the case of the legal defeasance option, 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 U.S. 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
U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had
not occurred. Notwithstanding the foregoing, the Opinion of Counsel required by the immediately preceding sentence with respect to a legal defeasance need not be delivered if all of the Notes not theretofore delivered to the Trustee 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;

premium, if any, and interest on such holder’s Notes on or after the due dates therefore or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes; 

(vii) 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 U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amount and in the same manner and at the
same times as would have been the case if such deposit and defeasance had not occurred; and 

  
 -83- 








 (viii) 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 Notes to be so defeased and discharged as contemplated by this Article VIII have been complied with.

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 VIII that, in the written opinion of a nationally recognized
firm of independent public accountants, a nationally recognized investment bank or a nationally recognized appraisal or valuation firm, delivered to the Trustee (which delivery shall only be required if U.S. Government Obligations have been so
deposited), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article VIII. 

Subject to any applicable abandoned property law, the Trustee and each 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 Trustee and each Paying Agent shall have no

accordance with this Article VIII 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 Notes so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or any Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with this Article VIII; provided, however, that, if the Company has made any payment of principal of, premium, if any, or interest on, any such Notes because of the reinstatement of its obligations,
the Company shall be subrogated to the rights of the holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or any Paying Agent.

 SECTION 9.02 With Consent of the Holders. The Company and the Trustee may amend this
Indenture, the Notes and the Guarantees, and any past Default or compliance with any provisions of this Indenture, the Notes or the Guarantees may be waived, with the consent of the Company and the holders of at least a majority in principal amount
of the Notes then outstanding voting as a single class. However, without the consent of each holder of an outstanding Note affected, no amendment or waiver may: 

(1) reduce the amount of Notes whose holders must consent to an amendment, 

(2) reduce the rate of or extend the time for payment of interest on any Note, 

(3) reduce the principal of or change the Stated Maturity of any Note, 

(4) reduce the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed in
accordance with Article III, 
 (5) make any Note payable in money other than that stated in such Note, 

(6) expressly subordinate the Notes or any Guarantee to any other Indebtedness of the Company or any Guarantor, 

(7) impair the right of any holder to receive payment of principal of, premium, if any, and interest on such holder’s
Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes, or 

(8) make any change in the amendment provisions which require each holder’s consent or in the waiver provisions. 

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. 
 After an amendment under this Section 9.02
becomes effective, the Company shall mail, or otherwise deliver in accordance with the procedures of the Depository, 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 Revocation and Effect of Consents
and Waivers. 
 (a) A consent to an amendment or a waiver by a holder of a Note shall bind the holder and every subsequent holder of that
Note or portion of the Note that evidences the same debt as the consenting holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such holder or subsequent holder may revoke the consent or waiver as to
such holder’s Note or portion of the Note 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 Notes have
consented. 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, the Guarantors and the Trustee. 

  
 -86- 








 (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 9.04 Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Company may
require the holder of the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the holder. Alternatively, if the Company or the Trustee so determine, the Company in
exchange for the Note shall issue and, upon written order of the Company signed by an Officer, the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not
affect the validity of such amendment, supplement or waiver. 
 SECTION 9.05 Trustee to Sign Amendments. The Trustee shall sign any
amendment, supplement or waiver authorized pursuant to this Article IX 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 receive indemnity satisfactory to it and shall be provided with, and (subject to Section 7.01) shall be fully protected in conclusively relying upon, (i) an Officers’ Certificate, (ii) 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 any Guarantors, enforceable against
them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof and (iii) if such amendment, supplement or waiver is executed pursuant to Section 9.02, evidence reasonably satisfactory to the
Trustee of the consent of the holders required to consent thereto. 
 SECTION 9.06 Additional Voting Terms; Calculation of Principal
Amount. All Notes issued under this Indenture shall vote and consent together on all matters (as to which any of such Notes may vote) as one class and no Notes 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 Notes have concurred in any direction, waiver or consent shall be made in accordance with this Article IX and Section 2.13. 

SECTION 9.07 Compliance with the 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 Notes shall comply with the TIA as then in effect. 
 ARTICLE X 

GUARANTEE 
 SECTION 10.01
Guarantee. 
 (a) Each Guarantor hereby jointly and severally guarantees, on an unsecured, unsubordinated basis, as a primary obligor
and not merely as a surety, to each holder and to the Trustee and its successors and assigns the performance and punctual payment when due, whether at Stated Maturity, by acceleration or otherwise, of all obligations of the Company under this
Indenture and the Notes, whether for payment of principal of, premium, if any, or interest (or Additional Interest, if any) on the Notes, expenses, indemnification or otherwise (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 any Guarantor, and that each Guarantor shall remain
bound under this Article X notwithstanding any extension or renewal of any Guaranteed Obligation. 

  
 -87- 








 (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 Notes or the Guaranteed Obligations. The Guarantee 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 Notes or any other agreement or otherwise; (ii) any extension or
renewal of this Indenture, the Notes or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security
held by any holder or the Trustee for the Guaranteed Obligations or each 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 each Guarantor, except as provided in Section 10.02(b). Each Guarantor hereby waives any right to which it may be entitled to have its Guarantee hereunder divided among the Guarantors, such that such Guarantor’s Guarantee
would be less than the full amount claimed. 
 (c) 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 obligations under this Indenture and the Notes or such Guarantor’s Guarantee hereunder prior to any amounts being claimed 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 and performance 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) The Guarantee of each Guarantor is, to the extent and in the manner set forth in this Article X, equal in right of payment to all existing
and future Pari Passu Indebtedness and senior in right of payment to all existing and future Subordinated Indebtedness of such Guarantor. 

(f) Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the Guarantee 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 Guarantee 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 Notes 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 Guaranteed 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. 
 (g) Each Guarantor agrees that its Guarantee shall remain in full force and
effect until payment in full of all the Guaranteed Obligations of such Guarantor. 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. 

  
 -88- 








 (h) 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 under this Indenture and the Notes. 
 (i) 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, 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 VI for the purposes of the 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 VI, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purposes of this Section 10.01. 

(j) Each Guarantor also agrees to pay any and all expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee in
enforcing any rights under this Section 10.01. 
 (k) Upon request of the Trustee, each Guarantor shall execute and deliver such
further instruments and do such further acts as may be reasonably necessary to carry out more effectively the purpose of this Indenture. 

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 each Guarantor shall not exceed the maximum amount that can be hereby guaranteed by the applicable Guarantor without rendering the Guarantee, as it relates to such Guarantor, voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally or capital maintenance or corporate benefit rules applicable to guarantees for obligations of affiliates. 

(b) A Guarantee as to any Guarantor shall automatically terminate and be of no further force or effect and such Guarantor shall be
automatically released from all obligations under this Article X upon: 
 (i) the sale, disposition, exchange or other
transfer (including through merger, consolidation, amalgamation or otherwise) of the Capital Stock (including any sale, disposition or other transfer following which the applicable Guarantor is no longer a Restricted Subsidiary), of the applicable
Guarantor if such sale, disposition, exchange or other transfer is made in a manner not in violation of this Indenture; 

  
 -89- 








 (ii) the designation of such Guarantor as an Unrestricted Subsidiary in
accordance with the provisions of Section 4.04 and the definition of “Unrestricted Subsidiary”; 
 (iii) the
Company’s exercise of its legal defeasance option or covenant defeasance option under Article VIII or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture; or 

(iv) such Restricted Subsidiary ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest
securing Credit Facility Indebtedness or other exercise of remedies in respect thereof. 
 SECTION 10.03 Successors and Assigns. This
Article X shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of and be enforceable by 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 Notes 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 X 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 X at law, in equity, by statute or otherwise. 

SECTION 10.05 Modification. No modification, amendment or waiver of any provision of this Article X, 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 any 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 which is required to become a Guarantor of the
Notes pursuant to Section 4.11 shall, within the time period set forth therein, execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit D hereto pursuant to which such Subsidiary shall become a
Guarantor under this Article X 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 certifying that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or 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, and subject to other customary exceptions, the Guarantee of such Guarantor is a valid and binding
obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms. 
 SECTION 10.07 Non-Impairment. The
failure to endorse a Guarantee on any Note shall not affect or impair the validity thereof.

principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, the Guarantors or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company
or the Guarantors shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustee actually

sheet and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions hereof.

of this Indenture, such provision of this Indenture shall control. 
 SECTION 11.15 Severability. In case any provision in this
Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby and such provision shall be ineffective only to the extent of such

with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 Exhibit A-5 








 [FORM OF REVERSE SIDE OF INITIAL NOTE] 

5.875% Senior Note Due 2022 
  

	1.	Interest 

 ENPRO INDUSTRIES, INC., a North Carolina corporation (such entity, 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 Note at the rate per annum shown above; provided, however, that
if a Registration Default (as defined in the Registration Rights Agreement) occurs, Additional Interest will accrue on this Note at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period
that occurs after the date on which such Registration Default occurs up to a maximum Additional Interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to the date on which all Registration Defaults
have been cured. The Company shall pay interest semiannually on March 15 and September 15 of each year (each an “Interest Payment Date”), commencing [            ]2. Interest on the Notes 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
[            ]3, 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 Notes, 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 Notes (except defaulted
interest) to the Persons who are registered holders at the close of business on March 1 or September 1 (each a “Record Date”) immediately preceding the Interest Payment Date even if Notes are canceled after the Record Date and on
or before the Interest Payment Date (whether or not a Business Day). Holders must surrender Notes to the 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 Notes represented by a Global Note (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 shall make all payments in respect of a certificated Note (including principal, premium, if any, and interest) at the
office of the 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 Notes may also be made,
in the case of a holder of at least $1,000,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written
notice to the Trustee or Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 

 

	3.	Paying Agent and Registrar 

 Initially, U.S. Bank National Association, as trustee under
the Indenture (the “Trustee”), will act as Paying Agent and Registrar. The Company may remove any Registrar or Paying Agent upon written 
  

 
  

	2 	To be March 15, 2015 for Notes issued on September 16, 2014. 


	3 	 To be September 16, 2014 for Notes issued on September 16, 2014. 



  
 Exhibit A-6 








 
notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a
successor Registrar or Paying Agent, as the case may be, as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to
the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Company or any of its wholly owned domestically organized Subsidiaries may act as Paying Agent
or Registrar. 
  

	4.	Indenture 

 The Company issued the Notes under an Indenture dated as of
September 16, 2014 (the “Indenture”), among the Company, the Guarantors and the Trustee. Capitalized terms used herein are used as defined in the Indenture, unless otherwise indicated. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). The Notes are subject to all terms and
provisions of the Indenture, and the holders (as defined in the Indenture) are referred to the Indenture for a statement of such terms and provisions. If and to the extent that any provision of the Notes limits, qualifies or conflicts with a
provision of the Indenture, such provision of the Indenture shall control. 
 The Notes are unsecured, unsubordinated obligations of the
Company. This Note is one of the Initial Notes referred to in the Indenture. The Notes include the Initial Notes and any Additional Notes. The Initial Notes and any Additional Notes may, at the Company’s option, be treated as a single class of
securities for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax
purposes, the Additional Notes will have a separate CUSIP number, if applicable. The Indenture imposes certain limitations on the ability of the Company and the Restricted Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, Incur Indebtedness, enter into consensual restrictions upon the payment of certain dividends and distributions by 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. 

The Guarantors (including each Wholly Owned Restricted Subsidiary of the Company that is required to guarantee the Guaranteed Obligations
pursuant to Section 4.11 of the Indenture) shall jointly and severally guarantee the Guaranteed Obligations pursuant to the terms of the Indenture.

Section 163(f)(2)(B) of the Code; (v) to conform the text of the Indenture, the Notes or the Guarantees to any provision of the “Description of Notes” in the Offering Memorandum to the extent that such provision in the Indenture,

respect to the Notes, (vii) to add collateral to secure the Notes; (viii) to release a Guarantor or any Guarantee of the Notes as permitted by the Indenture; (ix) to add to the covenants of the Company for the benefit of the holders

	14.	Defaults and Remedies 

 If an Event of Default (other than an Event of Default specified
in Section 6.01(f) or (g) of the Indenture with respect to the Company) occurs and is continuing, the Trustee by notice to the Company or the holders of at least 25% in principal amount of outstanding Notes by notice to the Company, with a
copy to the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. If an Event of
Default specified in Section 6.01(f) or (g) of the Indenture with respect to the Company occurs, the principal of, premium, if any, and interest on all the Notes will 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 outstanding Notes may rescind any such acceleration with respect to the Notes 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 vested in it
by the Indenture at the request or direction of any of the holders pursuant to the Indenture, unless such holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction. 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 Notes unless (i)
such holder has previously given the Trustee written notice that an Event of Default is continuing, (ii) holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy, (iii) such holders have
offered the Trustee security or indemnity satisfactory to it 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 Notes have not given the Trustee a direction inconsistent with such 

  
 Exhibit A-10 








 
request within such 60-day period. The holders of a majority in principal amount of outstanding Notes 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 the Indenture or, if the Trustee, being advised by counsel, determines that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceeding so directed would involve the Trustee in personal liability or expense for which it is not adequately indemnified, or,
subject to Section 7.01 of the Indenture, 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 reasonably satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
  

	15.	Trustee Dealings with the Company 

 The Trustee, in its individual or any other capacity,
may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	16.	No Recourse Against Others 

 No director, officer, employee, manager, incorporator or
holder of any Equity Interests in the Company or any direct or indirect parent company of the Company, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Indenture or the Guarantees, as
applicable, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of Notes by accepting a Note waives and releases all such liability. 

 

	17.	Authentication 

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

	18.	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). 

 

	19.	Holders Compliance with Registration Rights Agreement 

 Each holder of a Note, by
acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the holders with respect to a registration and the indemnification of the Issuer to the extent provided therein. 

 

	20.	Governing Law 

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

  
 Exhibit A-11 









	21.	CUSIP Numbers; ISINs 

 The Company has caused CUSIP numbers and ISINs to be printed on
the Notes and has directed the Trustee to use CUSIP numbers and ISINs in notices of redemption as a convenience to the holders. No representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification numbers printed thereon. 
 The Company will furnish to
any holder of Notes upon written request and without charge to the holder a copy of the Indenture which has in it the text of this Note.

 [FORM OF REVERSE SIDE OF EXCHANGE NOTE] 

5.875% Senior Note Due 2022 
  

	1.	Interest 

 ENPRO INDUSTRIES, INC., a North Carolina corporation (such entity, 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 Note at the rate per annum shown above[; provided, however,
that if a Registration Default (as defined in the Registration Rights Agreement) occurs, Additional Interest will accrue on this Note at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day
period that occurs after the date on which such Registration Default occurs up to a maximum Additional Interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to the date on which all Registration
Defaults have been cured]4. The Company shall pay interest semiannually on March 15 and September 15 of each year (each an “Interest Payment Date”), commencing
[            ]. Interest on the Notes 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
[            ], 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 Notes, 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 Notes (except defaulted
interest) to the Persons who are registered holders at the close of business on March 1 or September 1 (each a “Record Date”) immediately preceding the Interest Payment Date even if Notes are canceled after the Record Date and on
or before the Interest Payment Date (whether or not a Business Day). Holders must surrender Notes to the 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 Notes represented by a Global Note (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 shall make all payments in respect of a certificated Note (including principal, premium, if any, and interest) at the
office of the 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 Notes may also be made,
in the case of a holder of at least $1,000,000 aggregate principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such holder elects payment by wire transfer by giving written
notice to the Trustee or Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 

 

	3.	Paying Agent and Registrar 

 Initially, U.S. Bank National Association, as trustee under
the Indenture (the “Trustee”), will act as Paying Agent and Registrar. The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal
shall become effective until (i) if applicable, acceptance of an appointment by a successor Registrar or 
  

	4 	Insert if at the date of issuance of the Exchange Note any Registration Default has occurred with respect to the related Initial Notes during the interest period in which such date of issuance occurs 


  
 Exhibit B-5 








 
Paying Agent, as the case may be, as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the
Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Company or any of its wholly owned domestically organized
Subsidiaries may act as Paying Agent or Registrar. 
  

	4.	Indenture 

 The Company issued the Notes under an Indenture dated as of
September [16], 2014 (the “Indenture”), among the Company, the Guarantors and the Trustee. Capitalized terms used herein are used as defined in the Indenture, unless otherwise indicated. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). The Notes are subject to all terms and
provisions of the Indenture, and the holders (as defined in the Indenture) are referred to the Indenture for a statement of such terms and provisions. If and to the extent that any provision of the Notes limits, qualifies or conflicts with a
provision of the Indenture, such provision of the Indenture shall control. 
 The Notes are unsecured, unsubordinated obligations of the
Company. This Note is one of the Initial Notes referred to in the Indenture. The Notes include the Initial Notes and any Additional Notes. The Initial Notes and any Additional Notes may, at the Company’s option, be treated as a single class of
securities for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax
purposes, the Additional Notes will have a separate CUSIP number, if applicable. The Indenture imposes certain limitations on the ability of the Company and the Restricted Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, Incur Indebtedness, enter into consensual restrictions upon the payment of certain dividends and distributions by 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. 

The Guarantors (including each Wholly Owned Restricted Subsidiary of the Company that is required to guarantee the Guaranteed Obligations
pursuant to Section 4.11 of the Indenture) shall jointly and severally guarantee the Guaranteed Obligations pursuant to the terms of the Indenture. 
  

	5.	Redemption 

 On or after September 15, 2017, the Company may redeem the Notes 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 mailed (or caused to be mailed) by the Company by first-class mail, or delivered electronically if the Notes are held by The
Depository Trust Company (“DTC”), to each holder’s registered address (with a copy to the Trustee), at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest and
Additional Interest, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month period

whole at any time or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice mailed (or caused to be mailed) by the Company by first-class mail, or delivered electronically if the Notes are held by DTC, to each
holder’s registered address (with a copy to the Trustee), at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if

Notwithstanding the foregoing, at any time and from time to time on or prior to September 15, 2017, the Company may redeem in the
aggregate up to 35% of the original aggregate principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes) with the net cash proceeds of one or more Equity Offerings (1) by the Company or (2) by any
direct or indirect parent of the Company to the extent the net cash proceeds thereof are contributed to the common equity capital of the Company or are used to purchase Capital Stock (other than Disqualified Stock) of the Company, at a redemption
price (expressed as a percentage of principal amount thereof) of 105.875%, plus accrued and unpaid interest and Additional Interest, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant
Record Date to receive interest due on the relevant Interest Payment Date); provided, however, that at least 65% of the original aggregate principal amount of the Notes (calculated after giving effect to any issuance of Additional
Notes) must remain outstanding after each such redemption; provided, further, that such redemption shall occur within 90 days after the date on which any such Equity Offering is consummated upon not less than 30 nor more than 60
days’ notice mailed (or caused to be mailed) by the Company by first-class mail, or delivered electronically if the Notes are held by DTC, to the registered address of each holder of Notes being redeemed (with a copy to the Trustee) and
otherwise in accordance with the procedures set forth in the Indenture. 
 Notice of any redemption upon any Equity Offering may be given
prior to the completion thereof. In addition, any such redemption described above or notice thereof may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related
Equity Offering in the case of a redemption upon completion of an Equity Offering. 
  

	6.	Mandatory Redemption 

 The Company will not be required to make any mandatory redemption
or sinking fund payments with respect to the Notes. 
  

	7.	Notice of Redemption 

 Notices of redemption will be mailed (or caused to be mailed) by
first-class mail, or delivered electronically if the Notes are held by DTC, at least 30 but not more than 60 days before the redemption date, to each holder of Notes to be redeemed at its registered address (with a copy to the Trustee), except that
redemption notices may be mailed or otherwise delivered more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Article VIII
thereof. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the Company has deposited with the Paying Agent funds sufficient to pay the redemption price of, plus
accrued and unpaid interest on, the Notes or portions thereof to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture. 

  
 Exhibit B-7 









	8.	Repurchase of Notes 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
require the Company to repurchase all or any part of such holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, 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.

Registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a holder to pay any taxes required by law or permitted by the Indenture. The Company shall not
be required to make, and the Registrar need not register, transfers or exchanges of any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion thereof not to be redeemed) or of any Notes for a period of 15
days before the mailing of a notice of redemption of Notes to be redeemed. 
  

	10.	Persons Deemed Owners 

 The registered holder of this Note shall be treated as the owner
of it for all purposes. 
  

	11.	Unclaimed Money 

 Subject to any applicable abandoned property law, the Trustee and each
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 Trustee and each 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 Notes and the Indenture if the Company deposits with the Trustee cash in U.S. dollars, U.S. Government Obligations or a combination thereof sufficient to pay the principal of and premium (if any)

waived with the written consent of the holders of at least a majority in principal amount of the Notes then outstanding. 

  
 Exhibit B-8 








 The Company and the Trustee may amend the Indenture, the Notes and the Guarantees without notice
to or the consent of any holder (i) to cure any ambiguity, omission, mistake, defect or inconsistency; (ii) to provide for the assumption by a Successor Company (with respect to the Company) of the obligations of the Company under the
Indenture and the Notes; (iii) to provide for the assumption by a Successor Guarantor (with respect to any Guarantor) of the obligations of a Guarantor under the Indenture and its Guarantee; (iv) to provide for uncertificated Notes in
addition to or in place of certificated Notes, provided, however, that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated notes are described in
Section 163(f)(2)(B) of the Code; (v) to conform the text of the Indenture, the Notes or the Guarantees to any provision of the “Description of Notes” in the Offering Memorandum to the extent that such provision in the Indenture,
the Notes or the Guarantees was intended by the Company to be a verbatim recitation of a provision in the “Description of Notes” in the Offering Memorandum, as stated in an Officers’ Certificate; (vi) to add a Guarantee with
respect to the Notes, (vii) to add collateral to secure the Notes; (viii) to release a Guarantor or any Guarantee of the Notes as permitted by the Indenture; (ix) 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; (x) to comply with any requirement of the SEC in connection with qualifying, or maintaining the qualification of, the Indenture under the TIA; (xi) to make any change
that does not adversely affect the rights of any holder in any material respect; (xii) to provide for the appointment of a successor Trustee as permitted by this Indenture; (xiii) to effect any provisions of the Indenture or to make
changes to the Indenture to provide for the issuance of Additional Notes; or (xiv) to provide for the issuance of Exchange Notes or private exchange notes, which are identical to Exchange Notes except that they are not freely transferable. 

 

	14.	Defaults and Remedies 

 If an Event of Default (other than an Event of Default specified
in Section 6.01(f) or (g) of the Indenture with respect to the Company) occurs and is continuing, the Trustee by notice to the Company or the holders of at least 25% in principal amount of outstanding Notes by notice to the Company, with a
copy to the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. If an Event of
Default specified in Section 6.01(f) or (g) of the Indenture with respect to the Company occurs, the principal of, premium, if any, and interest on all the Notes will 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 outstanding Notes may rescind any such acceleration with respect to the Notes 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 vested in it
by the Indenture at the request or direction of any of the holders pursuant to the Indenture, unless such holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs, expenses and liabilities which might
be incurred by it in compliance with such request or direction. 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 Notes unless (i)
such holder has previously given the Trustee written notice that an Event of Default is continuing, (ii) holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy, (iii) such holders have
offered the Trustee security or indemnity satisfactory to it 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 Notes have not given the Trustee a direction inconsistent with such 

  
 Exhibit B-9 








 
request within such 60-day period. The holders of a majority in principal amount of outstanding Notes 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 the Indenture or, if the Trustee, being advised by counsel, determines that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceeding so directed would involve the Trustee in personal liability or expense for which it is not adequately indemnified, or,
subject to Section 7.01 of the Indenture, 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 reasonably satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
  

	15.	Trustee Dealings with the Company 

 The Trustee, in its individual or any other capacity,
may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	16.	No Recourse Against Others 

 No director, officer, employee, manager, incorporator or
holder of any Equity Interests in the Company or any direct or indirect parent company of the Company, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Indenture or the Guarantees, as
applicable, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of Notes by accepting a Note waives and releases all such liability. 

 

	17.	Authentication 

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

	18.	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). 

 

	19.	Governing Law 

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

	20.	CUSIP Numbers; ISINs 

 The Company has caused CUSIP numbers and ISINs to be printed on
the Notes and has directed the Trustee to use CUSIP numbers and ISINs in notices of redemption as a convenience to the holders. No representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification numbers printed thereon. 

  
 Exhibit B-10 








 The Company will furnish to any holder of Notes upon written request and without charge to the
holder a copy of the Indenture which has in it the text of this Note.

 This certificate is

 The undersigned represents and warrants to you that: 

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of
1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $100,000 principal amount of the Notes, and we are acquiring the Notes 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 Notes, and we invest in or purchase securities similar to the Notes 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 Notes 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 Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of
original issue and the last date on which either of the Company or any affiliate of the Company was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) in the United States
to a person whom we reasonably believe is a qualified institutional buyer (as defined in rule 144A under the Securities Act) in a transaction meeting the requirements of Rule 144A, (b) outside the United States in an offshore transaction in
accordance with Rule 904 of Regulation S under the Securities Act, (c) pursuant to an exemption from registration under the Securities Act provided by Rule 144 thereunder (if applicable) or (d) pursuant to an effective registration
statement under the Securities Act, in each of cases (a) through (d) in accordance with any applicable securities laws of any state of the United States. In addition, we will, 

  
 Exhibit C-1 








 
and each subsequent holder is required to, notify any purchaser of the Note evidenced hereby of the resale restrictions set forth above. The foregoing restrictions on resale will not apply
subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made to an institutional “accredited investor” prior to the Resale Restriction Termination Date, the transferor
shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and
the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant to clause 1(b), 1(c) or 1(d) above to require the delivery of an opinion of counsel, certifications or
other information satisfactory to the Company and the Trustee.

W I T N E S S E T H : 
 WHEREAS
the Company, certain Guarantors and the Trustee have heretofore executed an indenture, dated as of September 16, 2014 (as amended, supplemented or otherwise modified, the “Indenture”), providing for the issuance of the

WHEREAS Sections 4.11 and 10.07 of the Indenture provide that under certain circumstances the Company is required to cause the New Guarantor
to execute and deliver to the Trustee a supplemental indenture pursuant to which the New Guarantor shall guarantee the Guaranteed Obligations; and 

WHEREAS pursuant to Section 9.01 of the Indenture, the Trustee and the Company are authorized to execute and deliver this Supplemental
Indenture; 
 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby
acknowledged, the New Guarantor, the Company and the Trustee mutually covenant and agree for the equal and ratable benefit of the holders of the Notes as follows: 

1. Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recital hereto are used
herein as therein defined, except that the term “holders” in this Supplemental Indenture shall refer to the term “holders” as defined in the Indenture and the Trustee acting on behalf of and for the benefit of such holders. The
words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular Section hereof. 

2. Agreement to Guarantee. The New Guarantor hereby agrees, jointly and severally with all existing Guarantors (if any), to guarantee
the Guaranteed Obligations on the terms and subject to the conditions set forth in Article X of the Indenture and to be bound by all other applicable provisions of the Indenture and the Notes and to perform all of the obligations and agreements of a

Section 11.02 of the Indenture. 
 4. Ratification of Indenture; Supplemental Indentures Part of Indenture. Except as expressly
amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and
every holder of Notes heretofore or hereafter authenticated and delivered shall be bound hereby. 

  
 Exhibit D-1 








 5. Governing Law. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 6. Trustee Makes No Representation. The Trustee accepts the
amendments of the Indenture effected by this Supplemental Indenture on the terms and conditions set forth in the Indenture, including the terms and provisions defining and limiting the liabilities and responsibilities of the Trustee. Without
limiting the generality of the foregoing, the Trustee shall not be responsible in any manner whatsoever for or with respect to any of the recitals or statements contained herein, all of which recitals or statements are made solely by the Company, or
for or with respect to (i) the validity or sufficiency of this Supplemental Indenture or any of the terms or provisions hereof, (ii) the proper authorization hereof by the Company and the New Guarantor, in each case, by action or
otherwise, (iii) the due execution hereof by the Company and the New Guarantor or (iv) the consequences of any amendment herein provided for, and the Trustee makes no representation with respect to any such matters. 

7. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but
all of them together represent the same agreement. One signed copy is enough to prove this Supplemental Indenture. Notwithstanding the foregoing, the exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF
transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Supplemental Indenture and signature pages for all purposes. 

8. Effect of Headings. The Section headings of this Supplemental Indenture have been inserted for convenience of reference only, are
not intended to be considered a part hereof and shall not modify or restrict any of the terms or provisions here.
