Amendment to the Trademark License Agreement between Banco de Chile

 Exhibit 4.8 
 AMENDMENT TO THE TRADEMARK LICENSE AGREEMENT 
 AMENDMENT No. 1 (this “Amendment”)
dated as of February 27 2009, to the Trademark License Agreement (the “Original Trademark License Agreement”) dated on or around December 27, 2007, between Citigroup Inc., a Delaware corporation (“Citi”), and Banco de
Chile, a company organized and existing under the laws of the Republic of Chile (“BCH” and together with Citi, the “Parties”). Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the
Original Trademark License Agreement. 
 WHEREAS, the Parties have entered into the Original Trademark License Agreement which, among other
things and subject to the terms and conditions thereof, permits BCH to use certain Licensed Citi Marks; and 
 WHEREAS, the Parties wish to
amend the Original Trademark License Agreement as set forth in this Amendment. 
 NOW, THEREFORE, in consideration of the mutual promises and
covenants set forth herein and in the Original Trademark License Agreement and for other good and valuable consideration, the receipt and accuracy of which are hereby acknowledged, and intending to be legally bound, the Parties hereby agree as
follows: 
 ARTICLE 1 AMENDMENT 
 Section 1.1 Quality Control. Section 9(b) of the Original Trademark License Agreement is amended and restated in its entirety as follows: 
 “b)-1 
 Each of the BCH Parties acknowledges that it is essential to preserve the goodwill of the
Licensed Citi Marks and the integrity of the Authorized Services by maintaining the prestige and high reputation of the Licensed Citi Marks. Accordingly, all Authorized Services provided, advertised, marketed or promoted under or in connection with
the Licensed Citi marks shall be of a consistent and high standard of quality, commensurate with the prestige and high reputation of the business conducted by the BCH parties, and shall at all times be compliant with (i) all applicable Laws and
policies and procedures and (ii) the high standards of the Chilean financial services market in effect at from time to time. BCH will deliver a certificate that confirms BCH’s compliance with the standards set forth in this paragraph at
least once a year signed by a senior officer of the company with knowledge of the representations set forth in such certificate. This certificate shall be delivered to either (i) Citigroup, (ii) the Direction Committee (Comite de Direccion
- as such term is used in the Connectivity Agreement), or (iii) such other committee, entity or person as may be agreed between the parties. 

 b)-2 
 In addition to the standards set forth in paragraph 9 b)-1, Banco de Chile shall also be at all times compliant with any and all additional quality control standards (including those set forth in one or more of the
sub-schedules of Schedule 9) approved from time to time by Citi (after discussion with BCH, whose comments with respect to the same (including, but not limited to, comments related to implementation timelines, cost and local market standards) will
be reasonably considered by Citi). These additional quality control standards shall relate exclusively to the Proprietary Products and Services set forth in Schedule 1.(e)-A hereto, as amended from time to time by the parties so as to include
additional Proprietary Products and Services. As used herein, “Proprietary Products and Services” includes those products listed on Schedule 1.(e)-A and all other products and services that have been developed by Citi and are being
marketed by the BCH Parties and excludes all products and services developed by BCH which are not exclusively marketed under, or identified by, a Citi Licensed Mark and that would reasonably be expected to be considered to be products and services
of BCH by the Superintendent of Banks in Chile. The BCH Parties shall cooperate with Citi to permit Citi to review from time to time the Proprietary Products and Services to confirm compliance with the quality control standards. 
 b)-3 
 If any of the BCH Parties fails to
comply with any of the quality control standards set forth in Section 9b)-1 or those approved by Citi in accordance with Section 9b)-2, Citi shall notify BCH in writing of such non-compliance (specifying in detail the basis for such
non-compliance) and, provided that it is reasonable to expect such non-compliance to be cured within 180 days, BCH shall have an initial cure period of 90 days from the date such notice is given to become compliant with the quality control standards
specified in the notice. Such initial cure period may be automatically extended by BCH for a second 90 day period if it certifies in writing that it has made reasonable efforts to cure such non-compliance during the initial 90 day cure period and
provides a summary of those efforts (a “Cure Period Certificate”). If the BCH Parties fail to become complaint within 180 days after notice of non-compliance is given by Citi, BCH may request in writing at least 10 days before the end of
the second cure period that the cure period be extended for an additional 180 days, and Citi shall not unreasonably withhold its consent to such final extension. Concurrently with such request, BCH must also deliver another Cure Period Certificate.

 b)-4 
 The parties
acknowledge that the Authorized Services bearing the Licensed Citi Marks will be issued and provided by the BCH Parties and will also be subject to BCH’s own policies and procedures and quality control provisions.” 
 Section 1.2. Audit Rights. The reference to “Authorized Services” in Section 11 of the Original Trademark Agreement is deleted
and replaced by “Proprietary Products and Services”. 

 Section 1.3. Schedules. Schedule 1.(e)-A, which is attached hereto as Exhibit I to this
Amendment, is hereby made a part of the Original Trademark License Agreement. 
 ARTICLE II: MISCELLANEOUS 
 Section 2.1 Full Force and Effect. Except as expressly amended by this Amendment, the Original Trademark License Agreement remains unchanged,
and the Original Trademark License Agreement, as amended, is hereby ratified, approved and confirmed in all respects as the agreement between the Parties and shall remain in full force and effect. 
 Section 2.2 Governing Law. This Amendment shall be governed by and construed in accordance with the Requirements of Law of the State of New
York without regard to the conflict of law principles of such State. 
 Section 2.3. Counterparts. This Amendment may be executed
by the Parties in multiple counterparts which may be delivered by facsimile transmission. Each counterpart when so executed and delivered shall be deemed an original, and all such counterparts taken together shall constitute one and the same
instrument. 
 IN WITNESS WHEREOF, each Party has caused this Agreement to be duly executed on its behalf by an authorized officer as of the
date first above written.

(whether such money has been paid to it by the Company or any other obligor on the Notes), and such Paying Agent shall promptly notify the Trustee of any default by the Company (or any other obligor on the Notes) in making any such payment. The
Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written request to a Paying Agent,
require such Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent shall have no further liability for the money so paid over to the Trustee. If the Company or any Affiliate
of the Company acts as Paying Agent, it will, on or before each due date of any principal of, premium, if any, or interest on the Notes, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such

as the owner thereof for all purposes whether or not the Note shall be overdue, and neither the Company, the Trustee, nor any such agent shall be affected by notice to the contrary. Furthermore, any Holder of a Global Note shall, by acceptance of
such Global Note, agree that transfers of beneficial interests in such Global Note may be effected only through a book entry system maintained by the Holder of such Global Note (or its agent) and that ownership of a beneficial interest in the Note
shall be required to be reflected in a book entry. When Notes are presented to the Registrar or a co-Registrar with a request to register the transfer or to exchange them for an equal principal amount of Notes of other authorized denominations
(including an exchange of Notes for Exchange Notes), the Registrar shall register the transfer or make the exchange as requested if its requirements for 

  

 -39- 

 
such transactions are met (including that such Notes are duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee
and Registrar duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder); provided that no exchanges of Notes for Exchange Notes shall occur until a Registration Statement shall have
been declared effective by the SEC and that any Notes that are exchanged for Exchange Notes shall be cancelled by the Trustee. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Notes at
the Registrar’s request. No service charge shall be made for any registration of transfer or exchange or redemption of the Notes, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge
payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Section 2.11, 3.08 or 9.04).

and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company,

Registrar will have any responsibility or liability for any aspect of the Depositary’s records relating to, or payments made on account of, beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any of the
Depositary’s records relating to such beneficial ownership interests, or for transfers of beneficial interests in the Notes or any transactions between the Depositary and beneficial owners. 
 (b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors or their
respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with the rules and procedures of the Depositary and the provisions of Section 2.08. In addition, U.S. Physical Notes and Offshore
Physical Notes shall be transferred to all beneficial owners in exchange for 

  

 -40- 

 
their beneficial interests in the U.S. Global Note or the Offshore Global Note, respectively, (i)(A) if the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the U.S. Global Note or the Offshore Global Note, as the case may be, and a successor depositary is not appointed by the Company within 90 days of such notice, or (B) the Depositary has ceased
to be a clearing agency registered under the Exchange Act, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of U.S. Physical Notes and Offshore Physical Notes, (iii) if an Event of
Default has occurred and is continuing and the Registrar has received a request therefor from the Depositary or (iv) in accordance with the rules and procedures of the Depositary and the provisions of Section 2.08. 
 (c) Any beneficial interest in one of the Global Notes that is transferred to a person who takes delivery in the form of an interest in the other Global
Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial
interests in such other Global Note for as long as it remains such an interest. 
 (d) In connection with any transfer of a portion of the
beneficial interests in the U.S. Global Note or Offshore Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.07, the Registrar shall reflect on its books and records the date and a decrease in the
principal amount of the U.S. Global Note or Offshore Global Note in an amount equal to the principal amount of the beneficial interest in the U.S. Global Note or Offshore Global Note to be transferred, and the Company shall execute, and the Trustee
shall authenticate and deliver, one or more U.S. Physical Notes or Offshore Physical Notes, as the case may be, of like tenor and amount. 
 (e) In connection with the transfer of the entire U.S. Global Note or Offshore Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.07, the U.S. Global Note or Offshore Global Note, as the
case may be, shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and make available for delivery, to each beneficial owner identified by the Depositary in exchange for
its beneficial interest in the U.S. Global Note or Offshore Global Note, as the case may be, an equal aggregate principal amount of U.S. Physical Notes or Offshore Physical Notes, as the case may be, of authorized denominations. 
 (f) Any U.S. Physical Note delivered in exchange for an interest in the U.S. Global Note pursuant to paragraph (b), (d) or
(e) of this Section 2.07 shall, except as otherwise provided by paragraph (e) of Section 2.08, bear the legend regarding transfer restrictions applicable to the U.S. Physical Note set forth in
Section 2.02. 
 (g) Any Offshore Physical Note delivered in exchange for an interest in the Offshore Global Note pursuant to
paragraph (b), (d) or (e) of this Section 2.07 shall, except as otherwise provided by paragraph (e) of Section 2.08, bear the legend regarding transfer restrictions set forth in
Section 2.02. 
 (h) The registered Holder of a Global Note may grant proxies and otherwise authorize any person, including Agent
Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

of any proposed transfer of a Note to any Institutional Accredited Investor which is not a QIB (excluding Non-U.S. Persons):

or has otherwise advised the Company and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Note stating, or has otherwise
advised the Company and the Registrar in writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule

 -42- 

 
determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the
exemption from registration provided by Rule 144A or (y) an interest in the U.S. Global Note, the transfer of such interest may be effected only through the book entry system maintained by the Depositary. 
 (ii) If the proposed transferee is an Agent Member, and the Note to be transferred consists of U.S. Physical Notes, upon receipt by the
Registrar of the documents referred to in clause (i) and instructions given in accordance with the Depositary’s and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in
the principal amount of the U.S. Global Note in an amount equal to the principal amount of the U.S. Physical Notes to be transferred, and the Trustee shall cancel the U.S. Physical Note so transferred. 
 (c) Transfers of Interests in the Offshore Global Note or Unlegended Offshore Physical Notes. The following provisions shall apply

 -43- 

 (e) Private Placement Legend. Upon the registration of transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the registration of transfer, exchange or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend unless either (i) the circumstances contemplated by paragraph (a)(i)(x) or (d)(ii) of this Section 2.08 exist or (ii) there is
delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related transfer restrictions are required in order to maintain compliance with the provisions of
the Securities Act. 
 (f) General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of
such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture. The Registrar shall not register a
transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set forth in this Indenture. In connection with any transfer of Notes, each Holder agrees by its acceptance of the Notes to furnish the Registrar or
the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

 The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.07
or this Section 2.08. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

 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 Agent Members 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. 
 Section 2.09 Replacement Notes. If a mutilated Note is surrendered to the Trustee or if the Holder claims
that the Note has been lost, destroyed or wrongfully taken, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall issue and the Trustee shall authenticate a
replacement Note of like tenor and principal amount and bearing a number not contemporaneously outstanding; provided that the requirements of this Section 2.09 are met. If required by the Trustee or the Company, an indemnity bond
must be furnished that is sufficient in the judgment of both the Trustee and the Company to protect the Company, the Trustee or any Agent from any 

  

 -44- 

 
loss that any of them may suffer if a Note is replaced. The Company may charge such Holder for its expenses and the expenses of the Trustee in replacing a
Note. In case 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 and shall be entitled to the benefits of this Indenture. 
 The provisions of this Section 2.09 are exclusive and shall preclude (to the extent lawful) all other rights and remedies against the Company
and the Trustee with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes. 
 Section 2.10
Outstanding Notes. Notes outstanding at any time are all Notes that have been authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this Section 2.10 as not
outstanding. 
 If a Note is replaced pursuant to Section 2.09, it ceases to be outstanding unless and until the Trustee and the
Company receive proof satisfactory to them that the replaced Note is held by a protected purchaser. 
 If the Paying Agent (other than the
Company or an Affiliate of the Company) holds on a maturity date or Redemption Date money sufficient to pay Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them shall cease to accrue.

 A Note does not cease to be outstanding because the Company or one of its Affiliates holds such Note, provided, however,
that in determining whether the Holders of the requisite principal amount of the outstanding Notes have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Notes owned by the Company or any other obligor upon
the Notes or any Affiliate of the Company or of such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Notes which the Trustee has actual knowledge to be so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or of such other obligor. 
 Section 2.11 Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and execute and the Trustee shall
authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have insertions, substitutions, omissions and other variations determined to be appropriate by the Officers executing the temporary Notes,
as evidenced by their execution of such temporary Notes. If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency 

  

 -45- 

 
of the Company designated for such purpose pursuant to Section 4.02, without charge to the Holder. Upon surrender for cancellation of any one or
more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall be entitled to
the same benefits under this Indenture as definitive Notes. 
 Section 2.12 Cancellation. The Company at any time may deliver to
the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder which
the Company has not issued and sold. The Registrar and the 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, replacement or cancellation and shall dispose of them in accordance with its normal procedure. 
 Section 2.13 CUSIP Numbers. The Company in issuing the Notes may use a “CUSIP” number (if then generally in use), and the Company and the Trustee shall use such “CUSIP” number in notices of redemption or
exchange as a convenience to Holders; provided that any such notice shall state that no representation is made as to the correctness of such CUSIP number either as printed on the Notes or as contained in any notice of redemption or exchange
and that reliance may be placed only on the other identification numbers printed on the Notes; and provided further that failure to use CUSIP numbers in any notice of redemption or exchange shall not affect the validity or sufficiency
of such notice. The Company shall promptly notify the Trustee of any change in “CUSIP” number for the Notes. 
 Section 2.14
Defaulted Interest. If the Company defaults in a payment of interest on the Notes, it shall pay, or shall deposit with the Paying Agent money in immediately available funds sufficient to pay, the defaulted interest, plus (to the extent
lawful) any interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date. A special record date, as used in this Section 2.14 with respect to the payment of any defaulted interest, shall
mean the 15th day next preceding the date fixed by the Company for the payment of defaulted interest, whether or not such day is a Business Day. At least 15 days before the subsequent special record date, the Company shall mail to each Holder and to
the Trustee a notice that states the subsequent special record date, the payment date and the amount of defaulted interest to be paid. 
 Section 2.15 Issuance of Additional Notes. The Company shall be entitled to issue Additional Notes under this Indenture which shall have identical terms as the Notes issued on the Closing Date, other than with respect to the
date of issuance, issue price (including amount of interest deemed to have accrued since the last Interest Payment Date), and amount of interest payable upon a registration default as provided under a Registration Rights Agreement related thereto;
provided that each such issuance must be made in compliance with Section 4.03. The Company shall use commercially reasonable efforts to ensure that the Exchange Notes issued in exchange for the Notes issue on the Closing Date, any
Exchange Notes issued in exchange for any Additional Notes issued in a transaction exempt from the registration requirements of the Securities Act and any Additional Notes issued pursuant to an effective registration statement under the Securities
Act have the same CUSIP numbers. 
  

 -46- 

 With respect to any Additional Notes, the Company shall set forth in a resolution of its Board of
Directors (or a duly appointed committee thereof) and in an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information: 
 (1) the aggregate principal amount of Notes outstanding immediately prior to the issuance of such Additional Notes; 
 (2) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 
 (3) the issue price and the issue date of such Additional Notes (including the amount of interest deemed to have accrued since the last
Interest Payment Date); and 
 (4) whether such Additional Notes shall be restricted securities and bear the Private Placement
Legend or shall be registered securities and bear no such legend.

 Section 3.01
Right of Redemption. (a) Prior to June 30, 2013, the Company may, at its option, in whole or in part, at any time or from time to time, redeem any of the Notes upon not less than 30 nor more than 60 days’ prior notice mailed by
first class mail to each Holder’s last address as it appears in the Security Register, at a Redemption Price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued and unpaid interest, if any, to,

 (b) The Notes are redeemable, at the Company’s option, in whole or in part, at any time or from time to time, on or after June 30, 2013 and
prior to maturity, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s last address as it appears in the Security Register, at the following Redemption Prices (expressed in percentages of
principal amount), plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date that is on or prior to the Redemption Date to receive interest due on
an Interest Payment Date), if redeemed during the 12-month period commencing on June 30 of the following years: 
  

				
	 Year

time to time, redeem up to 35% of the aggregate principal amount of the Notes with the net proceeds from one or more Equity Offerings at a Redemption Price (expressed as a percentage of principal amount) of 108.875% of their principal amount, plus
accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the rights of Holders of record 

  

 -47- 

 
on the relevant Regular Record Date that is on or prior to the Redemption Date to receive interest due on an Interest Payment Date); provided,
however, that (i) at least 65% of the aggregate principal amount of Notes originally issued on the Closing Date remains outstanding immediately after each such redemption and (ii) notice of such redemption is mailed within 90 days
after the closing of the related Equity Offering. 
 Section 3.02 Notices to Trustee. If the Company elects to redeem Notes
pursuant to Section 3.01, it shall notify the Trustee in writing of the Redemption Date and the principal amount of Notes to be redeemed and the clause of this Indenture pursuant to which redemption shall occur. 
 The Company shall give each notice provided for in this Section 3.02 in an Officers’ Certificate at least 45 days before the Redemption
Date (unless a shorter period shall be satisfactory to the Trustee). 
 Section 3.03 Selection of Notes to Be Redeemed. If less
than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed in compliance with the requirements, as certified to it by the Company, of the principal national securities exchange, if any, on which the Notes
are listed or, if the Notes are not listed on a national securities exchange or automated quotation system, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate; provided that no Note of $1,000
in principal amount or less shall be redeemed in part. 
 The Trustee shall make the selection from the Notes outstanding and not previously
called for redemption. Notes in denominations of $1,000 in principal amount may only be redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 in principal amount or any integral multiple thereof) of Notes that have
denominations larger than $1,000 in principal amount. 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 and the Registrar promptly in
writing of the Notes or portions of Notes to be called for redemption. 
 Section 3.04 Notice of Redemption. With respect to any
redemption of Notes pursuant to Section 3.01, at least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail to each Holder whose Notes are to be redeemed.

 The notice shall identify the Notes to be redeemed and shall state: 
 (1) the Redemption Date; 
 (2) the Redemption Price (or the method of calculating the Redemption Price if the Redemption Price is not determinable as of the date of the notice); 
 (3) the name and address of the Paying Agent; 
 (4) that Notes called for redemption must be surrendered to the Paying Agent in order to collect the Redemption Price; 
  

 -48- 

 (5) that, unless the Company defaults in making the redemption payment, interest on Notes
called for redemption ceases to accrue on and after the Redemption Date and the only remaining right of the Holders is to receive payment of the Redemption Price plus accrued and unpaid interest to, but excluding, the Redemption Date upon surrender
of the Notes to the Paying Agent; 
 (6) that, if any Note is being redeemed in part, the portion of the principal amount
(equal to $1,000 in principal amount or any integral multiple thereof) of such Note to be redeemed and that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion
thereof will be issued upon cancellation of the original Note; and 
 (7) that, if any Note contains a CUSIP number as
provided in Section 2.13, no representation is being made as to the correctness of the CUSIP number either as printed on the Notes or as contained in the notice of redemption and that reliance may be placed only on the other
identification numbers printed on the Notes. 
 At the Company’s request (which request may be revoked by the Company at any time prior
to the time at which the Trustee shall have given such notice to the Holders), made in writing to the Trustee at least 45 days (or such shorter period as shall be satisfactory to the Trustee) before a Redemption Date, the Trustee shall give the
notice of redemption in the name and at the expense of the Company. If, however, the Company gives such notice to the Holders, the Company shall concurrently deliver to the Trustee an Officers’ Certificate stating that such notice has been
given. 
 Section 3.05 Effect of Notice of Redemption. Once notice of redemption is mailed, Notes called for redemption become
due and payable on the Redemption Date and at the Redemption Price. Upon surrender of any Notes to the Paying Agent, such Notes shall be paid at the Redemption Price, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date.

 Notice of redemption shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give
such notice, or any defect therein, shall not affect the validity of the proceedings for the redemption of Notes held by Holders to whom such notice was properly given. 
 Section 3.06 Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Paying Agent (or, if the Company is acting as the Paying Agent, shall segregate and hold in
trust as provided in Section 2.05) money sufficient to pay the Redemption Price of and accrued and unpaid interest on all Notes to be redeemed on that date other than Notes or portions thereof called for redemption on that date that have
been delivered by the Company to the Trustee for cancellation. 
 Section 3.07 Payment of Notes Called for Redemption. If notice
of redemption has been given in the manner provided above, the Notes or portion of Notes specified in such notice to be redeemed shall become due and payable on the Redemption Date at the Redemption Price stated therein, together with accrued and
unpaid interest to, but excluding, such 

  

 -49- 

 
Redemption Date, and on and after such date (unless the Company shall default in the payment of such Notes at the Redemption Price and accrued and unpaid
interest to, but excluding, the Redemption Date, in which case the principal, until paid, shall bear interest from the Redemption Date at the rate prescribed in the Notes), such Notes shall cease to accrue interest. Upon surrender of any Note for
redemption in accordance with a notice of redemption, such Note shall be paid and redeemed by the Company at the Redemption Price, together with accrued and unpaid interest, if any, to, but excluding, the Redemption Date; provided that
installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders registered as such at the close of business on the relevant Regular Record Date.

 COVENANTS 
 Section 4.01 Payment of Notes. The Company shall pay the principal of, premium, if any, and interest on the Notes on the dates and in the
manner provided in the Notes and this Indenture. An installment of principal, premium, if any, or interest shall be considered paid on the date due if the Trustee or Paying Agent (other than the Company, a Subsidiary of the Company, or any Affiliate
of any of them) holds on that date money designated for and sufficient to pay the installment. If the Company or any Affiliate of the Company acts as Paying Agent, an installment of principal, premium, if any, or interest shall be considered paid on
the due date if the entity acting as Paying Agent complies with the last sentence of Section 2.05. As provided in Section 6.09, upon any bankruptcy or reorganization procedure relative to the Company, the Trustee shall serve
as the Paying Agent, if any, for the Notes. 
 The Company shall pay interest on overdue principal and premium, if any, and interest on
overdue installments of interest, to the extent lawful, at the rate per annum specified in the Notes. 
 Section 4.02 Maintenance of
Office or Agency. The Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in
Section 13.02. 
 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 that no such designation or rescission shall 

  

 -50- 

 
in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, 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. 
 The Company hereby initially designates the Corporate Trust Office of the Trustee as such office of the Company in accordance with Section 2.04. 
 Section 4.03 Limitation on Indebtedness. (a) The Company will not, and will not permit any Restricted Subsidiary to, Incur any
Indebtedness (other than the Notes issued on the Closing Date, and any Exchange Notes exchanged therefor or for Additional Notes, and any other Existing Indebtedness); provided, however, that the Company and any Subsidiary Guarantor
may Incur Indebtedness if, after giving effect to the Incurrence of such Indebtedness and the receipt and application of the proceeds therefrom, the Consolidated Leverage Ratio of the Company would be greater than zero and less than 5.0:1.0.

 (b) Notwithstanding the foregoing, the Company and any Restricted Subsidiary (except as specified below) may Incur each and all of the
following: 
 (1) Indebtedness incurred under Credit Agreements outstanding at any time in an aggregate principal amount not
to exceed $294 million, less the aggregate amount of all Net Cash Proceeds of Asset Sales applied to permanently repay any such Indebtedness pursuant to Section 4.10; 
 (2) Indebtedness owed: 
 (A) to the Company; or 
 (B) to any Restricted Subsidiary; provided, however,
that any such Indebtedness of the Company or a Subsidiary Guarantor owing to a Restricted Subsidiary that is not a Subsidiary Guarantor is expressly subordinated in right of payment to the Notes or the Subsidiary Guarantee, as the case may be;
provided, further, that any event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the Company, another Restricted Subsidiary or the
holder of a Lien permitted by this Indenture) will be deemed, in each case, to constitute an Incurrence of such Indebtedness not permitted by this clause (2);

 (1) the consideration received by the Company or the
Restricted Subsidiary is at least equal to the fair market value of the assets sold or disposed of; and 
 (2) at least 75% of
the consideration received consists of cash, Temporary Cash Investments or the assumption of Indebtedness of the Company (other than Indebtedness that is subordinated in right of payment to the Notes) or a Restricted Subsidiary (other than
Indebtedness that is subordinated in right of payment to the Subsidiary Guarantee of such Restricted Subsidiary) and unconditional release of the Company or the Restricted Subsidiary from all liability on the Indebtedness assumed. 
 (b) Within 12 months after the date of consummation of such Asset Sale, the Company shall or shall cause the relevant Restricted Subsidiary to:

 (A) apply an amount equal to the Net Cash Proceeds of such Asset Sale to repay Indebtedness constituting First Lien
Obligations and permanently reduce the commitments in respect thereof; provided that (x) to the extent that the terms of First Lien Obligations (other than the Notes) require that such other First Lien Obligations be repaid with the Net
Cash Proceeds of Asset Sales prior to repayment of other Indebtedness, the Company and its Restricted Subsidiaries shall be entitled to repay such other First Lien Obligations prior to repaying the Notes and (y) subject to the foregoing clause
(x), if the Company or any Restricted Subsidiary shall so reduce such other First Lien Obligations, the Company shall equally and ratably reduce Obligations under the Notes through open-market purchases thereof (provided that such purchases
are consummated at a purchase price at or above 100% of the principal amount thereof) or by making an Offer to Purchase to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest,
if any, on the pro rata principal amount of the Notes purchased; or 
 (B) invest an equal amount, or the amount of Net Cash
Proceeds of such Asset Sale not so applied pursuant to clause (A) (or enter into a definitive agreement committing to so invest within such 12-month period, which investment shall be consummated within 12 months after the date of such
agreement ), in (i) property or assets (other than current assets) of a nature or type 

  

 -64- 

 
or that are used in a business similar or related to the nature or type of the property and assets of, or the business of, the Company and the Restricted
Subsidiaries existing on the date of such investment (as determined in good faith by the Board of Directors, whose determination shall be conclusive and evidenced by a Board Resolution) (a “Related Business”) or (ii) the
Capital Stock of a Person primarily engaged in a Related Business that becomes a Restricted Subsidiary as a result of such investment; and 
 (C) apply such Net Cash Proceeds (to the extent not applied pursuant to clause (A) or (B)) as provided in Section 4.10(c). 
 The amount of such Net Cash Proceeds required to be applied (or to be committed to be applied) during such 12-month period as set forth in the preceding sentence and not applied as so required by the end of such
period shall constitute “Excess Proceeds.” 
 (c) If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this Section 4.10 totals at least $20 million, the Company must commence, not later than the fifteenth Business Day of such month, and consummate an Offer to
Purchase from the Holders on a pro rata basis an aggregate principal amount of Notes and, to the extent permitted or required by the terms thereof, any other of the Company’s First Lien Obligations or other Senior Indebtedness secured by a Lien
permitted under this Indenture (which Lien is not subordinated to the Lien of the Notes with respect to the Collateral), equal to the Excess Proceeds on such date, at a purchase price equal to 100% of the principal amount of the Notes and such other
First Lien Obligations or Senior Indebtedness, if applicable, on the relevant Payment Date, plus, in each case, accrued interest (if any) to, but excluding, the Payment Date. If any Excess Proceeds remain after consummation of an Offer to Purchase,
the Company may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other First Lien Obligations or Senior Indebtedness tendered in response to such Offer to Purchase
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other First Lien Obligations or Senior Indebtedness to be purchased on a pro rata basis. Upon completion of the Offer to Purchase, the amount of Excess Proceeds shall
be reset to zero. For purposes of this Section 4.10(c), “Offer to Purchase” means, with respect to First Lien Obligations or other Senior Indebtedness other than the Notes, an offer to purchase such First Lien Obligations or
other Senior Indebtedness, which may be consummated, except as otherwise provided in this Section 4.10(c), in accordance with the terms of such First Lien Obligations or other Senior Indebtedness. 
 Section 4.11 Repurchase of Notes Upon a Change of Control. The Company shall commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding, at a purchase price equal to 101% of the principal amount thereof on the relevant Payment Date, plus accrued interest (if any) to, but excluding, the Payment Date.

done all things necessary to preserve and keep in full force and effect its existence and the existence of each of its Restricted Subsidiaries in accordance with the 

  

 -65- 

 
organizational documents of the Company and each Restricted Subsidiary and the rights (whether pursuant to charter, partnership certificate, agreement,
statute or otherwise), licenses and franchises of the Company and each Restricted Subsidiary; provided that the Company shall not be required to preserve any such right, license or franchise, or the existence of any Restricted Subsidiary, if
the maintenance or preservation thereof, in the judgment of the Company, is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole. 
 Section 4.13 Payment of Taxes and Other Claims. The Company agrees that it shall pay or discharge and shall cause its Restricted Subsidiaries

Subsidiary, (b) the income or profits of the Company or any such Restricted Subsidiary which is a corporation or (c) the property of the Company or any such Restricted Subsidiary and (ii) all material lawful claims for labor,
materials and supplies that, if unpaid, might by law become a lien upon the property of the Company or any such Restricted Subsidiary; provided that the Company shall not be required to pay or discharge, or cause to be paid or discharged, any
such tax, assessment, governmental charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which adequate reserves have been established. 
 Section 4.14 Maintenance of Properties and Insurance. The Company agrees that it shall cause all properties used or useful in the conduct of
its business or the business of any of the Restricted Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided that
nothing in this Section 4.14 shall prevent the Company or any Restricted Subsidiary from discontinuing the use, operation or maintenance of any of such properties or disposing of any of them, if such discontinuance or disposal is, in the
judgment of the Company or such Restricted Subsidiary having managerial responsibility for any such property, desirable in the conduct of the business of the Company or such Restricted Subsidiary. 
 The Company agrees it shall provide or cause to be provided, for itself and the Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations similarly situated and owning like properties with reputable insurers or with the government of the United States of America, or an agency or instrumentality thereof, in
such amounts, with such deductibles and by such methods as the Company in good faith shall determine to be reasonable and appropriate in the circumstances. 
 Section 4.15 Notice of Defaults. In the event that any Officer of the Company becomes aware of any Default or Event of Default, the Company shall, promptly after such Officer becomes aware thereof, deliver

case the Company will supply to the Trustee for forwarding to each Holder, without cost to any Holder), within the time periods specified in the SEC’s rules and regulations:

Section 4.17(a) shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, or in Management’s Discussion and Analysis of Financial Condition and Results of
Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company. 
 (c) The Company agrees that, for so long as any Notes remain outstanding, if at any time it is not required to file with the SEC the reports and other
information required by the preceding paragraphs, it will furnish to Holders of Notes and prospective investors in the Notes, upon request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 (d) Notwithstanding the foregoing provisions of this Section 4.17, for so long as the Company files the foregoing reports and other
information with the SEC, the Company will be deemed to have furnished such reports and other information to the Trustee if the Company has filed such reports and other information with the SEC via the SEC’s Electronic Data Gathering, Analysis
and Retrieval (EDGAR) filing system or any successor electronic filing system of the SEC and such reports are publicly available. 
  

 -67- 

 (e) Delivery of such reports, information and documents to the Trustee is for informational purposes only
and the Trustee’s receipt of such reports, information and documents 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 hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 Section 4.18
Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or interest on the Notes as contemplated herein, wherever enacted, now or at any time
hereafter in force, or that may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company hereby expressly waives all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 4.19 Future Subsidiary Guarantors. The Company shall cause each Person that becomes a Domestic Restricted Subsidiary of the Company
following the Closing Date (and is eligible to be a Subsidiary Guarantor under the definition of “Subsidiary Guarantor”) and any Foreign Restricted Subsidiary that Guarantees any Indebtedness of the Company or any Domestic Restricted
Subsidiary of the Company to (1) execute and deliver to the Trustee a supplemental indenture pursuant to which such Domestic Restricted Subsidiary or Foreign Restricted Subsidiary will guarantee the payment and performance of the Notes and
(2) execute and deliver an amendment, supplement or other instrument in respect of the Collateral Agreements necessary to cause such Restricted Subsidiary to become a grantor thereunder and take all action required thereunder to perfect the
Liens created thereunder, as well as to execute and deliver to the Trustee joinders to the First Lien Intercreditor Agreement, in each case, at the time such Person becomes a Domestic Restricted Subsidiary or Guarantees any such Indebtedness of the
Company or any Domestic Restricted Subsidiary, as applicable. 
 Section 4.20 After-Acquired Collateral. From and after the
Closing Date, if the Company or any Subsidiary Guarantor creates any additional security interest upon any property or asset that would constitute Collateral to secure any First Lien Obligations and that is not already subject to a Lien under the

 -68- 

 
Company becomes obligated to pay Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the
Company and the proposed payment date for the Additional Interest. The Trustee shall not at any time be under any duty or responsibility to any Holder of the Notes to determine the Additional Interest, or with respect to the nature, extent, or
calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

 Section 6.02
Acceleration. (a) If an Event of Default (other than an Event of Default specified in clause (7) or (8) of Section 6.01 that occurs with respect to the Company) occurs and is continuing under this
Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Company (and to the Trustee if such notice is given by the Holders), may, and the Trustee at the request of
such Holders shall, declare the principal amount of, premium, if any, and accrued interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal amount, premium, if any, and accrued interest shall be
immediately due and payable. In the event of a declaration of acceleration because an Event of Default set forth in clause (5) of Section 6.01 has occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to clause (5) of Section 6.01 shall be remedied or cured by the Company or the relevant Restricted Subsidiary or waived by
the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto. If an Event of Default specified in clause (7) or (8) of Section 6.01 occurs with respect to the
Company, the principal amount of, premium, if any, and accrued interest on the Notes then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the
Trustee or any Holder. 
 (b) The Holders of at least a majority in principal amount of the outstanding Notes, by written notice to the
Company and to the Trustee, may waive all past Defaults and rescind and annul a declaration of acceleration and its consequences if (1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest
on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. 
 (c) Notwithstanding the foregoing, to the extent elected by the Company, the sole remedy for an Event of Default relating to the failure to comply with
Section 4.17 and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act will for the first 120 days after the occurrence of such an Event of Default consist exclusively of the right to
receive Additional Interest on the Notes at an annual rate equal to 0.50% of the principal amount of the Notes. The Additional Interest will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date
following the date on which the Additional Interest begins to accrue on any Notes. The Additional Interest will accrue on all outstanding Notes from and including the date on which such Event of Default first occurs to, but excluding, the 120th day
thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On such 120th day (or earlier, if such Event of Default is cured or waived prior to such 120th day), such Additional Interest will cease to accrue and,
if such Event of Default has not been cured or waived prior to such 120th day, the Notes will be subject to acceleration as provided above. In the event the Company does not elect to pay Additional 

  

 -72- 

 
Interest upon an Event of Default in accordance with this Section 6.02(c), the Notes will be subject to acceleration as provided above. If the
Company elects to pay such Additional Interest, it will notify the Trustee and Paying Agent of such election on or before the close of business on the date on which such Event of Default first occurs. 
 Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, and at the direction of the Holders of at
least a majority in aggregate principal amount of the outstanding Notes shall, pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes, the Collateral Agreements (subject to the terms of the First Lien Intercreditor Agreement) 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. 
 Section 6.04 Waiver of Past Defaults. Subject to Sections 6.02, 6.07 and 9.02, the Holders of at least a majority in aggregate principal amount of the outstanding Notes, by notice to
the Trustee, may waive an existing Default or Event of Default and its consequences, except a Default in the payment of principal of, premium, if any, or interest on any Note as specified in clause (1) or (2) of
Section 6.01 or in respect of a covenant or provision of this Indenture which cannot be modified or amended without the consent of the Holder of each outstanding Note affected. Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

 Section 6.05 Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding Notes
may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee pursuant to this Indenture; provided, however, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving
of such direction; and provided, further, that the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes. 
 Section 6.06 Limitation on Suits. A Holder may not institute any proceeding, judicial or otherwise, with respect to this Indenture or the
Notes, or for the appointment of a receiver or trustee, or for any other remedy hereunder unless: 
 (1) the Holder has
previously given the Trustee written notice of a continuing Event of Default; 
 (2) the Holders of at least 25% in aggregate
principal amount of outstanding Notes shall have made a written request to the Trustee to pursue such remedy; 
 (3) such
Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense; 
  

 -73- 

 (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of indemnity; and 
 (5) during such 60-day period, the Holders of a majority in aggregate principal
amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request; 
 For purposes of
Section 6.05 and this Section 6.06, the Trustee shall comply with TIA Section 316(a) in making any determination of whether the Holders of the required aggregate principal amount of outstanding Notes have concurred in
any request or direction of the Trustee to pursue any remedy available to the Trustee or the Holders with respect to this Indenture or the Notes or otherwise under the law. 
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder. 

Section 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a
Note to receive payment of the principal of, premium, if any, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, shall not be impaired or affected without the consent
of such Holder. 
 Section 6.08 Collection Suit by Trustee. If an Event of Default in payment of principal, premium or interest
specified in clause (1), (2) or (3) of Section 6.01 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 of
the Notes for the whole amount of principal, premium, if any, and accrued interest remaining unpaid, together with interest on overdue principal, premium, if any, and, to the extent that payment of such interest is lawful, interest on overdue
installments of interest, in each case at the rate specified in the Notes, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any amounts due to the Trustee under Section 7.07. 
 Section 6.09 Trustee May
File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor of the Notes),
their creditors or their property and shall be entitled and empowered to collect and receive any monies, securities or other property payable or deliverable upon conversion or exchange of the Notes or upon any such claims and to distribute the same,
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07. Nothing herein contained shall be 

  

 -74- 

 
deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. Subject to the terms of the First Lien Intercreditor Agreement, if the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following
order: 
 First: to the Trustee and the other Indemnified Parties for all amounts due under Section 7.07; 
 Second: to Holders for amounts then due and unpaid for principal of, premium, if any, and interest on the Notes in respect of which or for the benefit of

discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This

payment of mutilated, destroyed, lost or wrongfully taken Notes in Section 2.09, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

 Section 6.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any
Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article Six

 (7) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such

 Section 7.03 Individual Rights of Trustee. 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 their respective Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the same with like rights. However, the Trustee
is subject to TIA Sections 310(b) and 311. 
 Section 7.04 Trustee’s Disclaimer. The Trustee (i) makes no
representation as to the validity or adequacy of this Indenture or the Notes, (ii) shall not be accountable for the Company’s use or application of the proceeds from the Notes and (iii) shall not be responsible for any statement in

 Section 7.05 Notice of Default. If any Default or any Event of Default
occurs and is continuing and if such Default or Event of Default is known to the Trustee, the Trustee shall mail to each Holder in the manner and to the extent provided in TIA Section 313(c) notice of the Default or Event of Default within 45
days after it occurs, unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any Note, the Trustee
shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice
is in the interest of the Holders. 
 Section 7.06 Reports by Trustee to Holders. Within 60 days after each May 15,
beginning with May 15, 2010, the Trustee shall mail to each Holder as provided in TIA Section 313(c) a brief report dated as of such May 15, if required by TIA Section 313(a). 
 A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange,
if any, on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange or of any delisting thereof. 
 Section 7.07 Compensation and Indemnity. The Company shall pay to each of the Trustee, the Collateral Agent, the Paying Agent and the
Registrar (together with any predecessor Trustee, Collateral Agent, Paying Agent and Registrar, each an “Indemnified Party”) such compensation as shall be agreed upon in writing for their respective services hereunder. The
compensation of the Trustee shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse each Indemnified Party upon request for all reasonable disbursements, expenses and advances incurred or made by
such Indemnified Party without negligence or bad faith on its part. Such expenses shall include the reasonable compensation and expenses of such Indemnified Party’s agents and counsel. 
 The Company and the Subsidiary Guarantors shall, jointly and severally, indemnify each Indemnified Party for, and hold it harmless against, any loss,
claim, damage, liability or expense incurred by it without gross negligence or willful misconduct on its part in connection with the acceptance or administration of this Indenture and the Collateral Agreements and its duties under this Indenture,
the Notes and the Collateral Agreements, including the costs and expenses of defending itself against any claim or liability and of complying with any process served upon it or any of its officers in connection with the exercise or performance of
any of its 

  

 -78- 

 
powers or duties under this Indenture, the Notes and the Collateral Agreements. An Indemnified Party shall notify the Company promptly of any claim of which
such Indemnified Party has received written notice for which it may seek indemnity under this Section 7.07. Failure by an Indemnified Party to so notify the Company shall not relieve the Company of its obligations hereunder, unless the
Company or any Subsidiary Guarantor is materially prejudiced thereby. The Company shall defend the claim and the Indemnified Party shall cooperate in the defense. Unless otherwise set forth herein, the Indemnified Party may have separate counsel and
the Company shall pay the reasonable fees and expenses of such counsel. Neither the Company nor any Subsidiary Guarantor shall be required to pay for any settlement made without its consent, which consent shall not be unreasonably withheld. Neither
the Company nor any Subsidiary Guarantor shall be required to reimburse any expense or indemnity against loss or liability determined to have been caused by the Indemnified Party through its own gross negligence or willful misconduct. 
 To secure the Company’s payment obligations in this Section 7.07, each Indemnified Party shall have a lien prior to the Notes on all
money or property held or collected by the Trustee or the Collateral Agent, in its capacity as Trustee or Collateral Agent, as the case may be, except money or property held in trust to pay principal of, premium, if any, and interest on particular
Notes. 
 If an Indemnified Party incurs expenses or renders services after the occurrence of an Event of Default specified in clause
(7) or (8) of Section 6.01, the expenses and the compensation for the services will be intended to constitute expenses of administration under Title 11 of the United States Bankruptcy Code or any applicable federal
or state law for the relief of debtors. 
 The provisions of this Section 7.07 (i) shall survive the resignation or removal
of the Trustee, the Collateral Agent, the Paying Agent or the Registrar and the termination of this Indenture and (ii) shall be in addition to any other indemnity provided by the Company or any Subsidiary Guarantor in favor of any Indemnified
Party under any other document or agreement. 
 The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent
applicable.

Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. 
 The Trustee may resign at any time by so notifying the Company in writing at least 30 days prior to the date of the proposed resignation. The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee by so
notifying the Trustee in writing and may appoint a successor Trustee with the consent of the Company. The Company may remove the Trustee if: (i) the Trustee is no longer eligible under Section 7.10; (ii) the Trustee is adjudged
a bankrupt or an insolvent; (iii) a receiver or other public officer takes charge of the Trustee or its property; or (iv) the Trustee becomes incapable of acting.

Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the outstanding Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Company. If the successor Trustee does not deliver its written acceptance required by the next succeeding paragraph of this Section 7.08 within 30 days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or the Holders of a majority in principal amount of the outstanding Notes may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after the delivery of
such written acceptance, subject to the lien provided in Section 7.07, (i) the retiring Trustee shall, upon transfer of its charges hereunder, transfer all property held by it as Trustee to the successor Trustee, (ii) the
resignation or removal of the retiring Trustee shall become effective and (iii) the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to
each Holder. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 
 If the Trustee is no longer eligible under Section 7.10 or shall fail to comply with TIA Section 310(b), any Holder who satisfies the
requirements of TIA Section 310(b) may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. If at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.08, the Trustee shall resign immediately in the manner and with the effect provided in this Section 7.08. 
 The Company shall give notice of any resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders. Each notice shall include the name of the successor Trustee and the address
of its Corporate Trust Office. 
 Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s
obligation under Section 7.07 shall continue for the benefit of the retiring Trustee. 
 Section 7.09 Successor Trustee
by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking association, the resulting, surviving or transferee
corporation or national banking association without any further act shall be the successor Trustee with the same effect as if the successor Trustee had been named as the Trustee herein, provided such corporation shall be otherwise qualified
and eligible under this Article. 
 Section 7.10 Eligibility. This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1). The Trustee shall have a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition that is subject to the requirements of applicable federal
or state supervising or examining authority. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in this Article.

 Section 7.11 Money Held in Trust. The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law and except for money held in trust under Article Eight.

 Section 7.12 Limitation on Duty of Trustee in Respect of Collateral; Indemnification. (a) Beyond the exercise of
reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of the Collateral Agent or any other agent or bailee or any income thereon or as to preservation
of rights against prior parties or any other rights pertaining thereto and the Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times
or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or
other agent or bailee selected by the Trustee in good faith. 
 (b) The Trustee shall not be responsible for the existence, genuineness or
value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the
extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the
title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty to ascertain or
inquire as to the performance or observance of any of the terms of this Indenture, the Collateral Agreements or the First Lien Intercreditor Agreement by the Company, the Subsidiary Guarantors, the Collateral Agent or the Credit Agreement Secured
Parties.

 Section 8.04 Application of Trust Money. Subject to Sections 8.05 and 8.06, the Trustee or
Paying Agent shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 8.01, 8.02 or 8.03, as the case may be, and shall apply the deposited money and the money from U.S. Government
Obligations in accordance with the Notes and this Indenture to the payment of principal of, premium, if any, and interest on the Notes; but such money need not be segregated from other funds except to the extent required by law. 
  

 -85- 

 Section 8.05 Repayment to Company. Subject to Sections 7.07, 8.01, 8.02
and 8.03, the Trustee and the Paying Agent shall promptly pay to the Company upon request set forth in an Officers’ Certificate any excess money held by them at any time and thereupon shall be relieved from all liability with respect to
such money. The Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal, premium, if any, or interest that remains unclaimed for two years; provided that the Trustee or Paying
Agent before being required to make any payment may cause to be published at the expense of the Company once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money at such Holder’s address
(as set forth in the Security Register) notice that such money remains unclaimed and that after a date specified therein (which shall be at least 30 days from the date of such publication or mailing) any unclaimed balance of such money then
remaining will be repaid to the Company. After payment to the Company, Holders entitled to such money must look to the Company for payment as general creditors unless an applicable law designates another Person, and all liability of the Trustee and
such Paying Agent with respect to such money shall cease. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Sections 8.01, 8.02 and 8.03 or the principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of outstanding Notes. 
 Section 8.06 Reinstatement. If the Trustee or Paying
Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 8.01, 8.02 or 8.03, as the case may be, 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 shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.01, 8.02 or 8.03, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with Section 8.01,
8.02 or 8.03, as the case may be; provided that, if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to
the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. 
 ARTICLE NINE

 (1) to cure any ambiguity, defect or inconsistency in this Indenture, the Collateral Agreements or the First Lien Intercreditor Agreement;
provided that such amendments or supplements shall not, in the good faith opinion of the Board of Directors of the Company as evidenced by a Board Resolution, adversely affect the interests of the Holders in any material respect; 

 

 -86- 

 (2) to comply with Article Five; 
 (3) to comply with any requirements of the SEC in connection with the qualification of this Indenture under the TIA;

Intercreditor Agreement; or 
 (12) to make any change that, in the good faith opinion of the Board of Directors of the
Company as evidenced by a Board Resolution, does not materially and adversely affect the rights of any Holder. 
 Section 9.02 With
Consent of Holders. Subject to Sections 6.04 and 6.07 and without prior notice to the Holders, the Company and the Subsidiary Guarantors, when authorized by their Board of Directors (as evidenced by a Board Resolution), and the
Trustee may amend this Indenture, the Collateral Agreements, the First Lien Intercreditor Agreement and the Notes with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, and the Holders of not less
than a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may waive future compliance by the Company and the Subsidiary Guarantors with any provision of this Indenture, the Collateral Agreements,
the First Lien Intercreditor Agreement or the Notes; provided, however, that no such modification, amendment or waiver may, without the consent of each affected Holder (with respect to any Notes held by a non-consenting Holder):

 (1) change the Stated Maturity of the principal of, or any installment of interest on, any Note; 
  

 -87- 

 (2) reduce the principal amount of, or interest or premium, if any, on any Note;

 (3) change the place or currency of payment of principal of, or interest or premium, if any, on any Note; 
 (4) impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity (or, in the case of a
redemption, on or after the Redemption Date) on any Note or any Subsidiary Guarantee; 
 (5) reduce the percentage of
outstanding Notes, the consent of whose Holders is necessary to modify or amend this Indenture or the Notes, waive future compliance with any provision of this Indenture or the Notes or waive past Defaults; 
 (6) waive a default in the payment of principal of, or interest or premium, if any, on the Notes; or 
 (7) release any Subsidiary Guarantee other than pursuant to the terms of this Indenture. 
 In addition, without the consent of Holders of at least 66 2/3% in aggregate principal amount of Notes then outstanding, an amendment, supplement or waiver may not: 
 (1) release all or substantially all of the Collateral; or 
 (2) modify the First Lien Intercreditor Agreement in any manner materially adverse to the Holders of the Notes other than in accordance
with this Indenture, the Collateral Agreements and the First Lien Intercreditor Agreement. 
 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, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. The Company will mail supplemental indentures to Holders upon request. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture or waiver. 
 Section 9.03 Revocation and Effect of Consent. Until an
amendment or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the Note of the 

  

 -88- 

 
consenting Holder, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to its
Note or portion of its Note. Such revocation shall be effective only if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver shall become effective
upon receipt by the Trustee of written consents from the Holders of the requisite percentage in principal amount of the outstanding Notes. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then, notwithstanding the last two sentences
of 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 consent to such amendment, supplement or waiver or to revoke any consent
previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. 
 After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it is of the type described in Section 9.02. In
case of an amendment or waiver of the type described in Section 9.02, the amendment or waiver shall bind each Holder who has consented to it and every subsequent Holder of a Note that evidences the same indebtedness as the Note of the
consenting Holder. 
 Section 9.04 Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a
Note, the Trustee may require the Holder to deliver such Note to the Trustee. At the Company’s expense, the Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder and the Trustee may place an
appropriate notation on any Note thereafter authenticated. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue, and the Trustee shall authenticate, a new Note that reflects the changed terms.
Failure to make the appropriate notation, or issue a new Note, shall not affect the validity and effect of such amendment, supplement or waiver. 
 Section 9.05 Trustee to Sign Amendments, Etc. The Trustee shall be provided with, and shall be fully protected in relying upon, an Opinion of Counsel complying with Section 13.03 and stating that the execution of any
amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture and that it will be valid and binding upon the Company. Subject to the preceding sentence, the Trustee shall sign such
amendment, supplement or waiver if the same does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver that affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Section 9.06 Conformity with Trust Indenture
Act. Every supplemental indenture executed pursuant to this Article Nine shall conform to the requirements of the TIA as then in effect.

 ARTICLE TEN 
 SUBSIDIARY GUARANTEES 
 Section 10.01 Subsidiary Guarantees. Subject to this Article
Ten, each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Note and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the
Notes or the obligations of the Company hereunder or thereunder, that: (a) the principal of, premium, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and
interest on the overdue premium, if any, and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with
the terms hereof and thereof; and (b) in the case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of
the extension or renewal, whether at maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, such Subsidiary Guarantor shall be obligated to pay such amount
immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 Subject to
Section 10.02, each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce
the Notes or this Indenture, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the Notes or this Indenture or any other
circumstance that might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Subsidiary Guarantee shall not be discharged except by complete performance of
the obligations contained in the Notes and this Indenture. 
 If any Holder or the Trustee is required by any court or otherwise to return to
the Company, any Subsidiary Guarantor or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or any Subsidiary Guarantor, any amount paid either to the Trustee or such Holder, this Subsidiary
Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 Each Subsidiary Guarantor agrees that it
shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between the
Holders and the Trustee, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of 

  

 -90- 

 
acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable
by such Subsidiary Guarantor for the purpose of this Subsidiary Guarantee. 
 Section 10.02 Limitation on Subsidiary Guarantor
Liability. Each Subsidiary Guarantor and, by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that this Subsidiary Guarantee does not constitute a fraudulent transfer or conveyance for purposes
of United States Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the
Trustee, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor under this Subsidiary Guarantee and this Article Ten shall be limited to the maximum amount as will, after giving
effect to such maximum amount and all other contingent and fixed liabilities of each Subsidiary Guarantor that are relevant under such laws, result in the obligations of such Subsidiary Guarantor under this Subsidiary Guarantee to not constitute a
fraudulent transfer or conveyance. 
 Section 10.03 Execution and Delivery of Subsidiary Guarantees. Each Subsidiary Guarantor
hereby agrees that its execution and delivery of this Indenture or any supplemental indentures pursuant to Section 4.19 and this Section 10.03 shall evidence its Subsidiary Guarantee set forth in Section 10.01
without the need for any further notation on the Notes. 
 Each of the Subsidiary Guarantors hereby agrees that its Subsidiary Guarantee set
forth in Section 10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation relating to such Subsidiary Guarantee. 
 If an Officer of a Subsidiary Guarantor whose signature is on this Indenture or any supplemental indenture no longer holds that office at the time the
Trustee authenticates the Notes or at any time thereafter, such Subsidiary Guarantor’s Subsidiary Guarantee shall be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of each Subsidiary Guarantor. 
 In the event that the Company creates or acquires any new Subsidiaries or other guarantors subsequent to the date of this Indenture, if required by
Section 4.19, the Company agrees to cause such Subsidiaries or other guarantors to execute supplemental indentures to this Indenture and Subsidiary Guarantees in accordance with Section 4.19 and this Article Ten, to
the extent applicable. In addition, the Company agrees to use commercially reasonable efforts to cause each of its Restricted Subsidiaries, whether existing on the date of this Indenture or created or acquired subsequent to the date of this
Indenture, that is otherwise eligible to be a Subsidiary Guarantor under the definition of “Subsidiary Guarantor” to obtain all material authorizations and consents of governmental authorities required in order for such Restricted
Subsidiary to guarantee the Notes at the earliest practicable date and to enter into a Subsidiary Guarantee promptly thereafter. For purposes of this Section 10.03, the requirement to use “commercially 

  

 -91- 

 
reasonable efforts” shall not be deemed to require the Company to make material payments in excess of normal fees and costs to or at the direction of
governmental authorities or to change the manner in which it conducts its business in any respect that the management of the Company shall determine in good faith to be adverse or materially burdensome. The Company further agrees that,
notwithstanding any other provision to the contrary in this Indenture, each such Restricted Subsidiary that does not execute and deliver this Indenture shall, upon execution and delivery of a supplemental indenture pursuant to
Section 4.19, be deemed to be a Subsidiary Guarantor for all purposes hereunder (including, without limitation, for purposes of this Article Ten). 
 Section 10.04 Release of Subsidiary Guarantor. (a) Any Subsidiary Guarantor shall be released and relieved of any obligations under its Subsidiary Guarantee and the Collateral Agreements (in respect
of the Notes Obligations), (i) upon any sale or other disposition (in a transaction that complies with this Indenture) by the Company and its Restricted Subsidiaries of their Capital Stock or other ownership interests in such Subsidiary
Guarantor such that such Subsidiary Guarantor immediately following such sale or disposition ceases to be a Subsidiary of the Company or any Restricted Subsidiary; (ii) upon the sale of all or substantially all of the assets of such Subsidiary
in a transaction that complies with this Indenture; (iii) if the Company properly designates that Subsidiary Guarantor as an Unrestricted Subsidiary under this Indenture; (iv) if the Company exercises its legal defeasance option pursuant
to Section 8.02 or its covenant defeasance option pursuant to Section 8.03; or (v) upon satisfaction and discharge of this Indenture or payment in full of the principal of, premium, if any, and interest on the Notes and
all other obligations of the Company and any Subsidiary Guarantor that are then due and payable. Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that one of the foregoing
requirements has been satisfied and the conditions to the release of a Subsidiary Guarantor under this Section 10.04 have been met, the Trustee shall execute any documents reasonably required in order to evidence the release of such
Subsidiary Guarantor from its obligations under its Subsidiary Guarantee. 
 (b) Any Subsidiary Guarantor not released, in accordance with
the terms of this Indenture, from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of, premium, if any, and interest on the Notes and for the other obligations of any Subsidiary Guarantor under this
Indenture as provided in and subject to this Article Ten. 
 Section 10.05 Subsidiary Guarantors May Consolidate, Etc., on
Certain Terms. Each Subsidiary Guarantor (other than any Subsidiary Guarantor whose Subsidiary Guarantee is to be released in accordance with Section 10.04) will not, and the Company will not cause or permit any Subsidiary Guarantor
to, consolidate with or merge with or into any Person other than the Company or any other Subsidiary Guarantor unless: 
 (1)
the Person formed by or surviving any such consolidation or merger (if other than the Subsidiary Guarantor) is a corporation, partnership or limited liability company organized and validly existing under the laws of the United States of America or
any jurisdiction thereof; 
  

 -92- 

 (2) such Person assumes by supplemental indenture, executed and delivered to the Trustee,
all of the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee and the performance of every covenant of such Subsidiary Guarantee and this Indenture; and 
 (3) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing.

delivery of such Officers’ Certificate or Opinion of Counsel. The Trustee shall, to the extent permitted by Section 7.02, accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained
in such Officers’ Certificate or Opinion of Counsel. 
 (c) If any Collateral is released in accordance with this Indenture or any
Collateral Agreement, the Trustee, upon receipt of all documentation required by Trust Indenture Act Section 314(d) in connection with such release as set forth in the Opinion of Counsel delivered pursuant to Section 12.04(a), upon
which the Trustee shall be permitted to conclusively rely, will, upon request of the Collateral Agent or the Company, deliver a certificate to the Collateral Agent and the Company acknowledging such receipt.

 Section 12.06 Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in
the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article Twelve upon the Company or a Subsidiary Guarantor with respect to the release, sale or other disposition of such property may be exercised by
such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or a Subsidiary Guarantor or of any officer or officers thereof required by the provisions of this
Article Eleven; and if the Trustee or the Collateral Agent shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee or the Collateral Agent, as the case may be. 

Section 12.07 Release upon Termination of the Company’s Obligations. In the event (i) that the Company delivers to the Trustee,
in form and substance acceptable to it, an Officers’ Certificate and Opinion of Counsel certifying that all the Obligations under this Indenture, the Notes and the Collateral Agreements (in respect of the Notes Obligations) have been satisfied
and discharged by the payment in full of the Company’s Obligations under the Notes, this Indenture and the Collateral Agreements (in respect of the Notes Obligations), and all such Obligations have been so satisfied, or (ii) a discharge,
legal defeasance or covenant defeasance of this Indenture occurs under Article Eight, all rights the Trustee, on behalf of the Holders, has in or to the Collateral, and any rights the Trustee, on behalf of the Holders, has under the Collateral
Agreements shall terminate, the Collateral Agent shall be deemed not to hold a Lien in the Collateral on behalf of the Trustee, and the Trustee, at the Company’s request, shall (and shall direct the Collateral Agent to) do or cause to be done,
at the Company’s sole cost and expense, all acts as the Company shall have determined to be reasonably necessary to release such Lien as soon as is reasonably practicable and as shall have been set forth in such request.

Indenture and the provisions of the First Lien Intercreditor Agreement, the provisions of the First Lien Intercreditor Agreement shall control.

with; provided, however, that, with respect to matters of fact, an Opinion of Counsel may rely on an Officers’ Certificate or certificates of public officials. 
 Section 13.05 Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing or may be embodied in or evidenced by
an electronic transmission which identifies the documents containing the proposal on which such consent is requested and certifies such Holders’ consent thereto and agreement to be bound thereby; and except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to the Trustee, and, where it is hereby expressly required, to the Company. Proof of execution of any such instrument or of a writing appointing any such

partnership or limited liability company, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the person executing the same,
may also be proved in any other manner which the Trustee deems sufficient. 
 (c) The ownership of Notes shall be proved by the Security
Register.

or upon any obligation, covenant or agreement of the Company or any Subsidiary Guarantor contained in this Indenture or in any of the Notes, or because of the creation of any Indebtedness represented thereby, shall be had against any incorporator or

 [REVERSE SIDE OF NOTE] 
 PAETEC HOLDING CORP. 
 8 7/8% Senior Secured Notes due 2017 
 1. Principal and Interest.

 The Company will pay the principal of this Note on June 30, 2017. 
 The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate per annum shown
above. 
 Interest will be payable semi-annually (to the holders of record of the Notes at the close of business on the June 15 or
December 15 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing on December 31, 2009. 
 [Pursuant to the Registration Rights Agreement among the Company, the Subsidiary Guarantors party thereto, Banc of America Securities LLC and Deutsche Bank Securities Inc., the Company and the Subsidiary Guarantors
will be obligated to consummate an exchange offer registered under the Securities Act (the “Exchange Offer”). Upon such Exchange Offer, the Holders of Notes shall have the right, subject to compliance with securities laws, to exchange such
Notes for Exchange Notes, which have been registered under the Securities Act, in like principal amount and having terms identical in all material respects to the Notes. The Holders of the Notes shall be entitled to receive certain Additional
Interest payments in the event such Exchange Offer is not consummated and upon certain other conditions, all pursuant to and in accordance with the terms of the Registration Rights Agreement. The Holder of this Note is entitled to the benefits of
such Registration Rights Agreement.]1 
 Holders may be
entitled to receive Additional Interest payments in the event the Company fails to file specified reports and other information with the SEC or to provide such reports and other information to the Trustee. 
 Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 29, 2009;
provided that, if there is no existing default in the payment of interest and this Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 The Company shall pay
interest on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent lawful, at a rate per annum that is 1% in excess of the rate otherwise payable.

 2. Method of Payment. 
 The Company will pay interest (except defaulted interest) on the principal amount of the Notes as provided above on each June 30 and December 31 commencing on December 31, 2009 to the Persons who are
Holders (as reflected in the Security Register at the close of business on the June 15 or December 15 immediately preceding the Interest Payment Date), in each case, even if the Note is cancelled on registration of transfer or registration
of exchange after such record date; provided that, with respect to the payment of principal, the Company will make payment to the Holder that surrenders this Note to a Paying Agent on or after June 30, 2017. 
 The Company will pay principal, premium, if any, and, as provided above, interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. However, the Company may pay principal, premium, if any, and interest by check payable in such money. It may mail an interest check to a Holder’s registered address (as reflected in the Security
Register). If a payment date is a date other than a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period. 
 3. Paying Agent and Registrar. 
 Initially, the
Trustee will act as authenticating agent, Paying Agent and Registrar. The Company may change any authenticating agent, Paying Agent or Registrar without notice to the Holders. The Company, any Subsidiary or any Affiliate of any of them generally may
act as Paying Agent, Registrar or co-Registrar. 
 4. Indenture: Limitations. 
 The Company issued the Notes under an Indenture dated as of June 29, 2009 (the “Indenture”), among the Company, the Guarantors party
thereto and The Bank of New York Mellon, as trustee (the “Trustee”). Capitalized terms 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. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in
the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. 
 The Notes are general obligations of the Company. 
 5. Optional Redemption. 
 The Notes are redeemable, at the Company’s option, in whole or in part, at any time or from time to time, on or after June 30, 2013 and prior to
maturity, upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s last address as it appears in the Security Register, at the following Redemption Prices (expressed in percentages of principal

and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the rights of Holders of record on the relevant Regular Record Date that is on or prior to the Redemption Date to receive interest due on an Interest Payment Date);
provided, however, that (i) at least 65% of the aggregate principal amount of Notes originally issued on the Closing Date remains outstanding immediately after each such redemption and (ii) notice of such redemption is mailed
within 90 days after the closing of the related Equity Offering. 
 Prior to June 30, 2013, the Company may, at its option, in whole or
in part, at any time or from time to time, redeem any of the Notes upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to each Holder’s last address as it appears in the Security Register, at a Redemption

be redeemed in part. On and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption, unless the Company defaults in the payment of the Redemption Price. 
 6. Repurchase Upon Change of Control. 
 The Company
shall commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all Notes then outstanding, at a purchase price equal to 101% of the principal amount thereof on the relevant Payment Date, plus accrued
interest (if any) to, but excluding, the Payment Date.
