RECITALS

A. Section 9.3(a) of the Merger Agreement provides that
it may be amended prior to the Company Required Vote if, and only if, such amendment is in writing and is

signed by each Party.

Agreement.

 

C. The Parties to the Merger Agreement desire to enter
into this Amendment.

 

NOW, THEREFORE, the parties hereto, intending to be legally
bound, hereby agree as follows:

 

AGREEMENT

 

1. Amendment of Section 6.7(b). Subsection (b) of Section 6.7
(Directors’ and Officers’ Insurance and Indemnification) of the Merger Agreement is hereby amended in its entirety,
to read in full as follows:

 

“(b) Prior to the Closing, the Company shall purchase,
and after the Effective Time the Surviving Corporation shall maintain, directors’ and officers’ liability insurance
covering, for a period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the directors
and officers of each Company Entity who are currently covered by the Company’s existing directors’ and officers’
liability insurance with respect to claims arising from facts or events that occurred before the Effective Time, on terms and conditions
no less favorable to such directors and officers than those in effect on the Signing Date; except that the aggregate of all premiums
for such insurance is not required to exceed $280,000, in the aggregate, for such insurance on the Signing Date. If the aggregate
of all premiums for such insurance exceeds such maximum amount, then the Surviving Corporation shall purchase as much coverage
per policy year as is reasonably available for such maximum amount.”

 

2. Amendment of Section 8.1(b)(i). Subsection (b)(i) of Section

has not been consummated on or before January 31, 2013 (the “Outside Date”); except that: (A) if (x) the Merger has
not been consummated by the Outside Date by reason of the non-satisfaction of the conditions set forth in Section 7.1(d) and (y)
all other conditions set forth in ARTICLE 7 have been satisfied (other than those conditions that, by their nature, can be satisfied
only upon the occurrence of the Closing) or, to the extent not prohibited by applicable Law, waived, then the Outside Date will
be March 31, 2013;

 

(B) the Company is not entitled to terminate this Agreement
pursuant to this clause (i) if the Company’s material breach of one or more of the Company’s obligations hereunder
or the material inaccuracy of one or more of the Company’s representations or warranties hereunder is the cause of or results
in the failure of the Merger to occur on or before the Outside Date; and (C) the Parent is not entitled to terminate this Agreement
pursuant to this clause (i) if the Parent’s material breach of one or more of its obligations hereunder is the cause of or
results in the failure of the Merger to occur on or before the Outside Date;”

 

3. No Other Amendment. Except as herein provided, all of the
terms, covenants and conditions of the Original Agreement shall remain in full force and effect. The Merger Agreement, as amended
hereby, are hereby ratified and confirmed and shall continue in full force and effect.

 

4. Counterparts. This Amendment may be executed in two or more
counterparts, each of which shall be deemed to be an original and which, together, shall constitute one and the same instrument.

date of its authentication. The Notes shall be issued in minimum denominations of U.S.$150,000 and integral multiples of U.S.$1.00
in excess thereof.

 

The terms and provisions contained in the
Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However,
to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture
shall govern and be controlling.

 

(b)          Global
Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note
Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive
form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule
of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding
Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes
from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time
to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect
the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made
by the Trustee or the Custodian, at the written direction of the Trustee, in accordance with written instructions given by the
Holder thereof as required by Section 2.07 hereof.

 

2.02.         Execution
and Authentication. At least one Officer must sign the Notes for the Company by manual or facsimile signature. If an Officer
whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.
A Note will not be valid until authenticated by the manual signature of a Responsible Officer of the Trustee. The signature will
be conclusive evidence that the Note has been authenticated under this Indenture.

 

The Trustee shall, upon receipt of a written
order of the Company signed by at least one Officer (an “Authentication Order”), authenticate Notes for
original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount
of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company
pursuant to one or more Authentication Orders, except as provided in Section 2.08 hereof.

 

    	27

    	 

    

  

The Trustee may appoint an authenticating
agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may
do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating
agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

 

2.03.         Registrar
and Paying Agent. The Company shall maintain an office or agency where Notes may be presented for registration of transfer
or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying
Agent”). The Registrar will keep a register of the Notes and of their registration of transfer and exchange. The Company
may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar
and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar
without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party
to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act
as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

 

The Company initially
appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global
Notes. The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with
respect to the Global Notes. Neither the Trustee nor any Agent shall
have any responsibility or liability for any actions taken or not taken by the Depositary.

 

2.04.         Luxembourg
Listing Agent, Sub-Paying Agent and Transfer Agent. The Company has appointed Deutsche Bank Luxembourg S.A. as Luxembourg listing
agent, Luxembourg sub-paying agent and Luxembourg transfer agent. The Company shall maintain such agencies so long as the Notes
are listed on the Luxembourg Stock Exchange and the rules of the exchange so require.

 

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

 

2.06.         Holder
Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of
the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar,
the Company shall furnish to the Trustee at least seven Business Days before each interest payment date and at such other times
as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA § 312(a).

2.07.       Transfer
and Exchange.

 

(a)          Transfer
and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes may be exchanged by the Company
for Definitive Notes if:

 

(i)          the
Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that
it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed
by the Company within 120 days after the date of such notice from the Depositary;

 

(ii)         the
Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Definitive Notes representing
the Notes; or

 

(iii)        there
has occurred and is continuing an Event of Default with respect to the Notes.

 

Upon the occurrence of any of the preceding
events in subparagraphs (i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct
the Trustee in writing. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.08 and 2.11
hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
this Section 2.07 or Sections 2.08 or 2.11 hereof, shall be authenticated and delivered in the form of, and shall be, a Global
Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.07(a), however, beneficial interests
in a Global Note may be transferred and exchanged as provided in Section 2.07(b) or (c) hereof.

 

(b)          Transfer
and Exchange of Beneficial Interests in the Global Notes. Beneficial interests in any Global Note may be transferred to Persons
who take delivery thereof in the form of a beneficial interest in a Global Note. The transfer and exchange of beneficial interests
in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the rules
and procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange. No written orders or instructions
shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.07(b).

 

    	29

    	 

    

 

(c)          Transfer
or Exchange of Beneficial Interests in Global Notes for Definitive Notes. If any holder of a beneficial interest in a Global
Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who
takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 2.07(b)
hereof, the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant
to Section 2.07(g) hereof, and the Company shall execute and the Trustee shall authenticate and deliver to the Person designated
in the written instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a
beneficial interest pursuant to this Section 2.07(c) will be registered in such name or names and in such authorized denomination
or denominations as the holder of such beneficial interest requests through written instructions to the Registrar from or through
the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such Definitive Notes to the Persons in whose
names such Notes are so registered.

 

(d)          Transfer
and Exchange of Definitive Notes for Beneficial Interests in Global Notes. A Holder of a Definitive Note may exchange such
Definitive Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof
in the form of a beneficial interest in a Global Note at any time. Upon receipt of a written request for such an exchange or transfer,
the Trustee shall cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount at
maturity of one of the Global Notes. If any such exchange or transfer from a Definitive Note to a beneficial
interest is effected pursuant to this Section 2.07(d) at a time when a Global Note has not yet been issued, the Company shall issue
and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more
Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

 

(e)          Transfer
and Exchange of Definitive Notes for Definitive Notes. A Holder of Definitive Notes may transfer
such Definitive Notes to a Person who takes delivery thereof in the form of a Definitive Note. Upon written request by a
Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 2.07(e), the Registrar shall
register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder
must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer
in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing.

 

(f)          Legends.
The following legends will appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically
stated otherwise in the applicable provisions of this Indenture.

 

(i)          Section
1145 Exemption Legend. Each Global Note and each Definitive Note (and all Notes issued in exchange
therefor or substitution thereof) shall bear the legend in substantially the following form:

 

“THE
SECURITIES REPRESENTED BY THIS NOTE HAVE BEEN ISSUED PURSUANT TO SECTION 1145 OF THE U.S. BANKRUPTCY CODE, AS AMENDED (THE “BANKRUPTCY
CODE”) THAT PROVIDES AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE
STATE STATUTES.”

 

(ii)         Global

OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY
OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY

OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE &

    	31

    	 

    

 

(g)          Cancellation
and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged
for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such
Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.12 hereof. At any time prior
to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented
by such Global Note will be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary
at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note
will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction
of the Trustee to reflect such increase.

 

(h)          General
Provisions Relating to Transfers and Exchanges.

 

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

 

(ii)         No
service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration
of transfer or exchange, but the Company or the Trustee 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 similar governmental charge payable
upon exchange or transfer pursuant to Sections 2.11, 3.06, 3.09, 4.10, 4.15, 4.24 and Section 9.04 hereof).

 

(iii)        All
Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will
be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the
Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

 

(iv)         Neither
the Registrar nor the Company shall be required:

 

(A)         to
issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before
the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

 

(B)         to
register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part; or

 

(C)         to
register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

 

    	32

    	 

    

 

(v)          Prior
to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the
Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal
of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by
notice to the contrary.

 

(vi)         The
Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

 

(vii)        All
certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.07 to
effect a registration of transfer or exchange may be submitted by facsimile.

 

(viii)      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 participants of the Depositary 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.

 

2.08.         Replacement
Notes. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction
of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order,
shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an
indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The
Company or the Trustee may charge for its expenses in replacing a Note.

 

Every replacement Note is an additional
obligation of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other
Notes duly issued hereunder.

 

2.09.         Outstanding
Notes. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with
the provisions hereof, and those described in this Section 2.09 as not outstanding. Except as set forth
in Section 2.10 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note;
however, Notes held by the Company or a Subsidiary of the Company shall be deemed to be not outstanding for purposes of Section
3.07(a) hereof.

 

If a Note is replaced pursuant to Section
2.08 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by
a protected purchaser.

 

If the principal amount of any Note is considered
paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

 

    	33

    	 

    

  

If the Paying Agent (other than the Company,
a Subsidiary or an Affiliate of any thereof) holds, on a Redemption Date or maturity date, money sufficient to pay Notes payable
on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

 

2.10.         Treasury
Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver
or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that a Responsible Officer of the Trustee actually knows are so owned will be so disregarded.

 

2.11.         Temporary
Notes. Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt
of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated
Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to
the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate final-form Definitive Notes
in exchange for temporary Notes.

 

Holders of temporary Notes will be entitled
to all of the benefits of this Indenture.

 

2.12.         Cancellation.
The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the
Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel
all Notes surrendered for registration of transfer, exchange, payment, redemption, repurchase, replacement or cancellation in accordance
with its internal procedures (subject to the record retention requirement of the Exchange Act). Upon the Company’s written
request, certification of the cancellation of all canceled Notes will be delivered to the Company. The Company may not issue new
Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

 

2.13.         Defaulted
Interest. If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner
plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special
record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company
shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date
may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record
date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will
mail or cause to be mailed or, if sent through DTC, send in accordance with DTC’s applicable procedures, to Holders a notice
that states the special record date, the related payment date and the amount of such interest to be paid.

 

    	34

    	 

    

  

2.14.         CUSIP
Numbers. The Company in issuing the Notes may use one or more “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in notices of repurchase as a convenience to Holders; provided that
any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or
as contained in any notice of a repurchase and that reliance may be placed only on the other identification
numbers printed on the Notes, and any such repurchase shall not be affected by any defect in or omission of such numbers. The Company
shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

 

2.15.         Ranking;
Security for and Parity of Notes. All Notes issued and outstanding hereunder rank on a parity with each other Note, and each
Note shall be secured equally and ratably by this Indenture and the Collateral Documents with each other Note, without preference,
priority or distinction of any one thereof over any other by reason of difference in time of issuance or otherwise, and each Note
shall be entitled to the same benefits and security in this Indenture and the Collateral Documents as each other Note. The Company
shall be responsible for the continued maintenance, priority and perfection of such security interest as set forth in the Collateral
Documents.

 

2.16.         Additional
Notes. The Company may, from time to time, subject to compliance with any other applicable provisions of this Indenture, without
the consent of the Holders, create and issue pursuant to this Indenture Additional Notes having terms and conditions identical
to those of the other Notes other than with respect to the date of issuance, issue price and the date from which interest will
accrue. The Notes and the Additional Notes, if any, shall be treated as a single class for all purposes of this Indenture, including,
without limitation, Article IX hereof. However, if Additional Notes that are treated as part of a single class under this Indenture
with the Notes are not fungible with the Notes for U.S. federal income tax purposes such Additional Notes will be assigned a CUSIP,
ISIN and common code different from those assigned to the Notes.

 

Article
III

 

Redemption and Prepayment

 

3.01.         Notices
to Trustee. If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it
must furnish to the Trustee, at least 45 days (or such shorter period as agreed by the Trustee) but not more than 60 days before
a Redemption Date, an Officers’ Certificate setting forth:

 

(a)          the
clause of this Indenture pursuant to which the redemption shall occur;

 

(b)          the
Redemption Date;

 

(c)          the
principal amount of Notes to be redeemed; and

 

(d)          the
redemption price.

 

    	35

    	 

    

 

3.02.         Selection
of Notes to Be Redeemed or Purchased. If less than all of the Notes are to be redeemed or purchased in an offer to purchase
at any time, the Trustee shall select Notes for redemption or purchase in compliance with the requirements of the principal securities
exchange, if any, on which the Notes are listed, or if the Notes are not listed on a securities exchange, by lot or by such other
method as the Trustee shall deem to be fair and appropriate and in accordance with DTC procedures.

 

In the event of partial redemption or purchase
by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor
more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for
redemption or purchase.

 

The Trustee shall promptly notify the Company
in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase,
the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in minimum amounts of U.S.$150,000
and whole multiples of U.S.$1.00 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased,
the entire outstanding amount of Notes held by such Holder, even if not a multiple of U.S.$1.00, shall be redeemed or purchased.
Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase
also apply to portions of Notes called for redemption or purchase.

 

3.03.         Notice
of Redemption. Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail or cause to be mailed, by first-class mail or, if sent through DTC, send in accordance with DTC’s
applicable procedures, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that
redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance
of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles VIII or XII hereof.

 

The notice will identify the Notes to be
redeemed and will state:

 

(a)          the
Redemption Date;

 

(b)          the
redemption price;

 

(c)          if
any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption
Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation
of the original Note;

 

(d)          the
name and address of the Paying Agent;

 

(e)          that
Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

 

(f)          that,
unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and
after the Redemption Date;

 

    	36

    	 

    

 

(g)          the
paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

 

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

 

At the Company’s written request,
the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that
the Company has delivered to the Trustee, at least 15 days (or such shorter period as agreed by the Trustee) prior to the date
such notice of redemption is to be sent, an Officers’ Certificate requesting that the Trustee give such notice and setting
forth the information to be stated in such notice as provided in the preceding paragraph.

 

3.04.         Effect
of Notice of Redemption. Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption
become irrevocably due and payable on the Redemption Date at the redemption price. A notice of redemption may not be conditional.

 

3.05.         Deposit
of Redemption or Purchase Price. On or before the Business Day prior to the redemption or purchase date, the Company shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest
on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any
money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or
purchase price of, and accrued interest on, all Notes to be redeemed or purchased.

 

If the Company complies with the provisions
of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions
of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior
to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note
was registered at the close of business on such record date and no additional interest will be paid to Holders whose Notes are
redeemed. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the
failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption
or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each
case at the rate provided in the Notes and in Section 4.01 hereof.

 

3.06.         Notes
Redeemed or Purchased in Part. Upon surrender of a Note that is redeemed or purchased in part, the Company shall issue and,
upon receipt of an Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Company a new Note
equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

 

3.07.         Optional
Redemption. (a) At any time prior to June 15, 2017, the Company may on any one or more occasions redeem up to 35% of the aggregate
principal amount of Notes issued under this Indenture at a redemption price of 106% of the principal amount thereof, plus accrued
and unpaid interest and Additional Amounts, if any, to the Redemption Date, using cash in an amount up to the amount of the net
cash proceeds of a sale of common Equity Interests (other than Disqualified Stock) of the Company; provided that:

 

    	37

    	 

    

 

(i)          at
least 65% of the aggregate principal amount of Notes originally issued under this Indenture (excluding Notes held by the Company
and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

 

(ii)         the
redemption occurs within 90 days of the date of the closing of such sale of Equity Interests.

 

(b)          At
any time prior to June 15, 2017, the Company may also redeem all or a part of the Notes upon not less than 30 nor more than 60
days’ written notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium
as of, and accrued and unpaid interest and Additional Amounts, if any, to the Redemption Date, subject to the rights of Holders
of Notes on the relevant record date to receive interest due on the relevant interest payment date.

 

(c)          On

notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest
and Additional Amounts, if any, on the Notes redeemed, to the applicable Redemption Date, if redeemed during the periods indicated
below, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant interest payment

	Year	 	Percentage	 
	From June 15, 2017 through June 14, 2018	 	 	103.00	%
	From June 15, 2018 through June 14, 2019	 	 	101.50	%
	From June 15, 2019 and thereafter	 	 	100.00	%

 

(d)          Unless
the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called
for redemption on the applicable Redemption Date.

 

(e)          Any
redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof; provided
that, in the case of a redemption pursuant to Section 3.07 for the purposes of any notice required by Section 3.01 or 3.02,
the redemption price may be stated to be “the redemption price determined in accordance with Section 3.07(b)” or “the
redemption price determined in accordance with Section 3.07(c),” as the case may be.

 

3.08.         Mandatory
Redemption. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. The
Company may at any time and from time to time purchase Notes in the open market or otherwise.

 

    	38

    	 

    

 

3.09.         Offer
to Purchase by Application of Excess Proceeds. In the event that, pursuant to Section 4.10 hereof, the Company is required
to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures
specified below.

 

The Asset Sale Offer shall be made to all
Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set
forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer
will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except
to the extent that a longer period is required by applicable law (the “Offer Period”). No later than
three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company shall
apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu
Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and such other
pari passu Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in
the same manner as interest payments are made.

 

If the Purchase Date is on or after an interest
record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose
name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who
tender Notes pursuant to the Asset Sale Offer.

 

Upon the commencement of an Asset Sale Offer,
the Company shall send, by first-class mail, a notice to each of the Holders, with a copy to the Trustee. The notice will contain
all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which
shall govern the terms of the Asset Sale Offer, will state:

 

(a)          that
the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale
Offer will remain open;

 

(b)          the
Offer Amount, the purchase price and the Purchase Date;

 

(c)          that
any Note not tendered or accepted for payment will continue to accrue interest;

 

(d)          that,
unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to
accrue interest on after the Purchase Date;

 

(e)          that
Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples
of U.S.$1.00 only; provided that any unpurchased balance is in a minimum denomination of U.S.$150,000 or an integral multiple
of U.S.$1.00 in excess of U.S.$150,000;

 

(f)          that
Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form
entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer,
to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified
in the notice at least three Business Days before the Purchase Date;

 

    	39

    	 

    

 

(g)          that
Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives,
not later than the close of business on the second Business Day preceding the expiration of the Offer Period, a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for
purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

 

(h)          that,
if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the
Offer Amount, the Company shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based
on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed
appropriate by the Company so that only Notes in minimum denominations of U.S.$150,000, and integral multiples of U.S.$1.00 in
excess thereof, will be purchased); and

 

(i)          that
Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered (or transferred by book-entry transfer).

 

On or before the Purchase Date, the Company
shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes
or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate
stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section
3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days
after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by
such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon written
request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such
Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly
mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer
on the Purchase Date.

 

Other than as specifically provided in this
Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06
hereof.

 

3.10.         Redemption
for Changes in Withholding Tax. The Company may at its option at any time, upon giving not less than 30 nor more than 60 days’
notice to Holders, redeem all (but not less than all) of the Notes then outstanding, at 100% of the aggregate principal amount
thereof, plus accrued and unpaid interest and Additional Amounts, if any, to such Redemption
Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment
date), in the event the Company has become, or would become, obligated to pay, on the next date on which any amount would be payable
with respect to such Notes, any Additional Amounts in excess of the Additional Amounts the Company would be obligated to pay if
payments made on the Notes were subject to withholding or deduction of Mexican taxes at a rate in excess of 4.9 percent (“Excess
Additional Amounts”) as a result of:

 

    	40

    	 

    

 

(a)          any
change in, or amendment to, the laws (including any regulations promulgated thereunder) of the relevant
Tax Jurisdiction; or

 

(b)          any
change in the official application, administration or interpretation of such laws or regulations in
the relevant Tax Jurisdiction (each of (a) and (b) a “Change of Tax Law”),

 

if (1) the Change of Tax Law is announced
on or after the Issue Date (or, if later, the date a jurisdiction becomes a relevant Tax Jurisdiction), (2) if there has been a
further issuance, such obligation to pay Excess Additional Amounts would have arisen absent a further issuance of the Notes pursuant
to this Indenture, and (3) such obligation to pay Excess Additional Amounts cannot be avoided by the Company taking reasonable
measures available to it (including, without limitation, changing the jurisdiction from or through which payments are made).

 

Notwithstanding the foregoing, no such notice
of redemption may be given earlier than 60 days prior to the earliest date on which the Company (or any relevant Guarantor, as
applicable) would be obligated to pay such Excess Additional Amounts.

 

Prior to the giving of any notice of redemption
of the Notes pursuant to the foregoing, the Company shall deliver to the Trustee (1) an Officers’ Certificate stating that
the conditions precedent to the right of the Company to so redeem have occurred and that the obligation to pay Excess Additional
Amounts cannot be avoided by the Company by taking reasonable measures available to it, and (2) a written opinion of independent
legal counsel of recognized standing in the relevant Tax Jurisdiction addressed to the Trustee to the effect that the Company has
become obligated to pay Excess Additional Amounts as a result of a Change of Tax Law.

 

The foregoing provisions will apply mutatis
mutandis to any successor Person to the Company after such successor Person becomes a party to this Indenture.

 

For so long as the Notes are listed and
admitted for trading on the Euro MTF of the Luxembourg Stock Exchange, and to the extent the rules of the Luxembourg Stock Exchange
so require, the Company shall provide a copy of any such notice to the Luxembourg Stock Exchange. Notices of redemption will be
given in accordance with the provisions set forth under Section 3.03.

of the Trustee.

 

The Company may also from time to time designate
one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations; provided, however, that no such designation or rescission will 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.

to the Company); and

 

    	42

    	 

    

 

(iii)        in
the event that the Company is not subject to Section 13 or 15(d) of the Exchange Act or exempt from reporting pursuant to Rule
12g3-2(b) of the Exchange Act, the Company shall make available, upon request, to any Holder of the Notes and any prospective purchaser

Company shall make the information and reports referred to in this Section 4.03 available to securities analysts and prospective
investors upon request. For so long as the Notes are listed on the Euro MTF, the alternative market of the Luxembourg Stock Exchange
and the rules of the Luxembourg Stock Exchange so require, the above information will also be made available in Luxembourg through
the offices of Deutsche Bank Luxembourg S.A., the Luxembourg listing agent.

 

(c)          If
the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information

statements or in the footnotes thereto, and in the section entitled “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.

 

(d)          Delivery

the Company proposes to take with respect thereto.

 

    	43

    	 

    

 

(b)          So
long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants or the applicable
policies of the Company’s accountants, the year-end financial statements delivered pursuant to Section 4.03 hereof shall
be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established
international reputation) that in making the examination necessary for certification of such financial statements, nothing has
come to their attention that would lead them to believe that the Company has violated any provisions of Article IV or Article V
hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that
such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation.

 

(c)          So
long as any of the Notes are outstanding, the Company shall deliver to the Trustee, forthwith upon any Officer becoming aware of
any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

 

4.05.         Taxes.
The Company shall pay or discharge, and will cause each of its Restricted Subsidiaries to pay or discharge, prior to delinquency,
all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings

4.06.         Stay,
Extension and Usury Laws. The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that
it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this
Indenture; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law, and covenants that it shall not, by resort to any such law, 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
has been enacted.

 

4.07.         Restricted
Payments.  (a) The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly:

 

(i)          declare

(A)         no
Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

taken as a whole; plus

 

(4)         to
the extent that any Unrestricted Subsidiary of the Company designated as such after the date of this Indenture is redesignated
as a Restricted Subsidiary after the date of this Indenture, the lesser of (i) the Fair Market Value of the Company’s Investment

incurrence of Permitted Refinancing Indebtedness;

 

(iv)         (A)
to the extent required by law, or by the by laws of any Restricted Subsidiary in effect on the date of this Indenture, or (B) so
long as no Default has occurred and is continuing or would be caused thereby and, in the case of this clause (B), provided that
no intercompany notes are outstanding pursuant to clause (a) of the definition of “Permitted Investments,” the payment

than cash and Indebtedness) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted
Payment. The Fair Market Value of any assets or securities that are required to be valued by this Section 4.07 will be determined
by the Board of Directors of the Company whose resolution with respect thereto shall be delivered to the Trustee. The Board of
Directors’ determination must be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking
firm of international standing if the Fair Market Value exceeds U.S.$6,000,000.

 

4.08.         Dividend
and Other Payment Restrictions Affecting Subsidiaries. (a) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction
of any kind on the ability of any Restricted Subsidiary to:

 

(i)          pay
dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries or with respect
to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any of its
Restricted Subsidiaries;

 

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

 

(iii)        pay
any Indebtedness owed to the Company or any Restricted Subsidiary; or

 

(iv)         sell,
lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

 

    	47

    	 

    

 

(b)          The
restrictions in Section 4.08(a) hereof shall not apply to encumbrances or restrictions existing under
or by reason of:

 

(i)          agreements
governing Existing Indebtedness as in effect on the date of this Indenture and any amendments, restatements, modifications, renewals,
supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications,
renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect
to such dividend and other payment restrictions than those contained in those agreements on the date of this Indenture;

 

(ii)         this
Indenture, the Notes and the Note Guarantees;

 

(iii)        applicable
law, rule, regulation or order or the applicable by-laws of the Company or any of its Restricted Subsidiaries as in effect on the
date of this Indenture;

 

(iv)         any
instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as
in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with
or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the
case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

 

(v)          customary
non-assignment provisions in contracts and licenses entered into in the ordinary course of business;

 

(vi)         purchase
money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions
on the property purchased or leased of the nature described in clause (iv) of Section 4.08(a) hereof;

 

(vii)        any
agreement for the sale or other disposition of all or substantially all the stock or assets of a Restricted Subsidiary that restricts
distributions by that Restricted Subsidiary pending the sale or other disposition;

 

(viii)      Permitted
Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing
Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness
being refinanced;

 

(ix)         Liens
permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets
subject to such Liens;

 

(x)          customary
provisions relating to assets or properties in which the Company has Investments in joint ventures, provided that the Company was
allowed to make such Investment pursuant to the other terms of this Indenture; and

 

(xi)         customary
provisions existing in the documentation governing any Permitted Securitization.

 

    	48

    	 

    

 

4.09.         Incurrence
of Indebtedness and Issuance of Preferred Stock. (a) The Company shall not and shall not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently
or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and
the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares
of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or issue Disqualified
Stock, and the Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if the Leverage Ratio, as
of the Calculation Date, would have been no greater than (i) 4.25 to 1 in the case of any incurrence or issuance on or before December
31, 2013, (ii) 4.00 to 1 in the case of any incurrence or issuance on or after January 1, 2014 and on or before December 31, 2014,
and (iii) 3.50 to 1 in the case of any incurrence or issuance on or after January 1, 2015, determined on a pro forma basis (including
a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified
Stock or the preferred stock had been issued, as the case may be, as of the Calculation Date.

 

(b)          The
provisions of Section 4.09(a) hereof shall not prohibit, so long as no Default or Event of Default has
occurred and is continuing, the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

 

(i)          the
incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

 

(ii)         the
incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees to be issued
in accordance with the terms and conditions of the Plan;

 

(iii)        the
incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, financings
or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price (whether
in an asset acquisition or acquisition of Equity Interests) or cost of design, construction, installation or improvement of property,
plant or equipment used in the Permitted Business of the Company or any of its Restricted Subsidiaries, in an aggregate principal
amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any
Indebtedness incurred pursuant to this clause (iii), not to exceed U.S.$15,000,000 at any time outstanding;

 

(iv)         the
incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net
proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than Intercompany
Indebtedness) that was permitted by this Indenture to be incurred under the first paragraph of this covenant or clauses (i), (ii)
or (iii) of this Section 4.09(b);

 

(v)          the
incurrence by the Company or any of its Wholly-Owned Restricted Subsidiaries of Intercompany Indebtedness between or among the
Company and any of its Wholly-Owned Restricted Subsidiaries; provided, however, that:

 

    	49

    	 

    

 

(A)         if
the Company or any Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior
payment in full in cash of all obligations with respect to the Notes, in the case of the Company, or the Note Guarantee, in the
case of a Guarantor; and

 

(B)         (1)
any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than
the Company or a Wholly-Owned Restricted Subsidiary of the Company and (2) any sale or other transfer of any such Indebtedness
to a Person that is not either the Company or a Wholly-Owned Restricted Subsidiary of the Company, will be deemed, in each case,
to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the
case may be, not permitted by this clause (v); and

 

(C)         such
Indebtedness is otherwise incurred in accordance with Section 4.23 hereof.

 

(vi)         the
issuance by any of the Company’s Wholly-Owned Restricted Subsidiaries to the Company or to any of its Wholly-Owned Restricted
Subsidiaries that is a Guarantor of shares of preferred stock; provided, however, that:

 

(A)         any
subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than
the Company or a Wholly-Owned Restricted Subsidiary of the Company that is a Guarantor;

 

(B)         any
sale or other transfer of any such preferred stock to a Person that is not either the Company or a Wholly-Owned Restricted Subsidiary
of the Company that is a Guarantor, and

 

(C)         will
be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted
by this clause (vi);

 

(vii)        the
incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations for the purpose
of managing the Company’s (or any Restricted Subsidiary’s) exposure to fluctuations in interest rates with respect
to Indebtedness permitted to be Incurred by the Company pursuant to this Indenture or protecting the Company (or its Restricted
Subsidiaries) against currency fluctuations in the ordinary course of business and not for speculative purposes;

 

(viii)      the
guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that
was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed
is subordinated to or pari passu with the Notes, then the Guarantee shall be subordinated or pari passu, as applicable,
to the same extent as the Indebtedness guaranteed;

 

    	50

    	 

    

 

(ix)         the
incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness constituting reimbursement obligations with respect
to letters of credit issued in the ordinary course of business in respect of workers’ compensation claims or self-insurance,
or other Indebtedness with respect to reimbursement type obligations regarding workers’ compensation claims;

 

(x)          the
incurrence by the Company or any Restricted Subsidiary of Indebtedness consisting of performance and other similar bonds and reimbursement
obligations Incurred by the Company or any Restricted Subsidiary securing the performance of contractual,
franchise, concession or license obligations of the Company or a Restricted Subsidiary;

 

(xi)         Attributable
Debt with Respect to a Sale and Leaseback Transaction to the extent such Sale and Leaseback Transaction complies with the provisions
under Section 4.20;

 

(xii)        Indebtedness
arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except
in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business provided, however,
that such Indebtedness is extinguished within five Business Days of incurrence;

 

(xiii)      Indebtedness
of the Company, to the extent the net proceeds thereof in their entirety are (i) used solely to purchase Notes tendered in a Change
of Control Offer or (ii) concurrently deposited to defease the Notes as described under Article XII hereof;

 

(xiv)        Indebtedness
consisting of (i) the financing of insurance premiums or (ii) take or pay obligations in supply agreements, in each case in the
ordinary course of business; and

 

(xv)         the
incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount at
any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or
discharge any Indebtedness incurred pursuant to this clause (xv), but excluding the indebtedness permitted by clauses (i) through
(xiv), not to exceed U.S.$20,000,000.

 

The Company shall not incur, and shall not
permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment
to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right
of payment to the Notes and the applicable Note Guarantee on substantially identical terms.

 

    	51

    	 

    

 

For purposes of determining compliance with
this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of
Permitted Debt described in clauses (i) through (xv) above or is entitled to be incurred pursuant to Section 4.09(a) hereof, the
Company shall be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion
of such item of Indebtedness, in any manner that complies with this Section 4.09. The accrual of interest, the accretion or amortization
of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms,
the reclassification of preferred stock as Indebtedness due to a change in accounting principles, the reclassification of accounts
payable as Indebtedness and the payment of dividends on Disqualified Stock or preferred stock of Restricted Subsidiaries in the
form of additional shares of the same class of Disqualified Stock or preferred stock of Restricted Subsidiaries will not be deemed
to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock of Restricted Subsidiaries for purposes
of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment is included
in Consolidated Interest Expense of the Company as accrued. Notwithstanding any other provision of this Section 4.09, the maximum
amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed
to be exceeded solely as a result of fluctuations in exchange rates or currency values.

 

The amount of any Indebtedness outstanding
as of any date will be:

 

(A)         the
accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

 

(B)         the
principal amount of the Indebtedness, in the case of any other Indebtedness; and

 

(C)         in
respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

 

(1)         the
Fair Market Value of such assets at the date of determination; and

 

(2)         the
amount of the Indebtedness of the other Person.

 

For purposes of determining compliance with
any U.S. dollar denominated restriction on the incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness
denominated in a foreign currency shall be calculated based on the relevant currency exchange rate determined as the average daily
observed currency exchange rates reported by the Federal Reserve Bank of New York for the trailing 30 calendar day period, including
the date of incurrence, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness. The
principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness
being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such refinancing
indebtedness is denominated calculated based on the relevant currency exchange rates as calculated in the first sentence of this
paragraph.

 

4.10.         Asset
Sales.

 

(a)          Non-Collateral
Asset Sales. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

 

    	52

    	 

    

 

(i)          the
Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal
to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of as determined in good faith
by the Company’s Board of Directors (including as to the value of all non-cash consideration); and

 

(ii)         at
least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash and
is received at the time of such dispositions. For purposes of this provision, each of the following shall be deemed to be cash:

 

(A)         Cash
Equivalents;

 

(B)         any
liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary
(other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that
are assumed by the transferee of any such assets pursuant to a customary assumption agreement in which the transferee releases
the Company or such Restricted Subsidiary from further liability;

 

(C)         any
securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash within 30 days following the closing of such Asset Sale, to the
extent of the cash received in that conversion; and

 

(D)         any
Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate
fair market value, taken together with all other Designated Non-cash Consideration previously received pursuant to this clause
(D), not to exceed 1.0% of Total Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market
value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent
changes in value.

 

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

 

(1)         to
permanently repay any Indebtedness, other than subordinated Indebtedness or any Indebtedness of a Subsidiary that is not a Guarantor
and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments
with respect thereto;

 

(2)         to
acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect
to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company; or

 

(3)         to
purchase long-term property or assets or make a capital expenditure used or useful in a Permitted Business.

 

    	53

    	 

    

 

Pending the final application of any Net
Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that
is not prohibited by this Indenture.

 

(b)          Collateral
Asset Sales. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate a Collateral Asset
Sale unless:

 

(i)          the
Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of the Collateral Asset
Sale at least equal to the Fair Market Value of such Collateral;

 

(ii)         with
respect to each such Collateral Asset Sale, the Company delivers an Officers’ Certificate to the Collateral Agent and the
Trustee dated no more than 15 days prior to the date of consummation of the relevant Collateral Asset Sale, certifying that such
sale complies with clause (a) above;

 

(iii)        at
least 75% of the consideration received for the Collateral sold by the Company or its Restricted Subsidiaries, as the case may
be, shall be in the form of cash or Cash Equivalents received at the time of such Collateral Asset Sale; provided that any other
consideration received for such Collateral shall constitute Collateral pursuant to appropriate Collateral Documents to which the
owner thereof is a party; and

 

(iv)         the
Net Proceeds therefrom shall be paid directly by the purchaser thereof to the Collateral Agent, as additional Collateral.

 

In the case of any Collateral Asset Sale,
the Company, within 360 days from the date of consummation of a Collateral Asset Sale, may apply all of the Net Proceeds therefrom
to purchase or otherwise invest in Replacement Collateral. Any such Net Proceeds not so applied will be applied to make an Asset
Sale Offer in accordance with the terms described under Section 3.09 hereof and this Section 4.10. In the case of a Collateral
Asset Sale that represents all or substantially all of the Collateral, all of the Net Proceeds therefrom will be immediately applied
to make an Asset Sale Offer in accordance with Section 3.09 hereof and this Section 4.10.

 

(c)          Event
of Loss. If the Company or a Restricted Subsidiary suffers an Event of Loss, the Net Proceeds therefrom will be paid directly
by the party providing such Net Proceeds to the Collateral Agent, pursuant to the applicable Collateral Document, as additional
Collateral. As any portion or all of the Net Proceeds from any such Event of Loss are received by the Collateral Agent, the Company
may apply all of such amount or amounts, as received, together with all interest earned thereon, individually
or in combination, (1) to purchase or otherwise invest in Replacement Collateral and (2) to restore the relevant Collateral. In
the event that the Company elects to restore the relevant Collateral pursuant to the foregoing clause (2), within 180 days of receipt
of such Net Proceeds from an Event of Loss, the Company shall:

 

(i)          give
the Trustee irrevocable written notice of such election, and

 

    	54

    	 

    

 

(ii)         enter
into a binding commitment to restore such Collateral, a copy of which will be supplied to the Trustee, and will have 360 days from
the date of such binding commitment to complete such restoration, which will be carried out with due diligence. The Company shall
take such action, at its sole expense, as may be required to ensure that the Collateral Agent has, from the date of such purchase
or investment, a first ranking Lien on such Replacement Collateral.

 

Any such Net Proceeds that the Company does
not elect to apply within such 180 day period or does not actually apply within such 360 day period will be applied to make an
Asset Sale Offer in accordance with Section 3.09 hereof and this Section 4.10.

 

(d)          Replacement
Collateral. In the event that the Company decides pursuant to the foregoing provisions to apply any portion of the Net Proceeds
from a Collateral Asset Sale or an Event of Loss to purchase or otherwise invest in Replacement Collateral:

 

(i)          the
Company shall deliver an Officers’ Certificate to the Collateral Agent and the Trustee dated no more than 30 days prior to
the date of consummation of the relevant investment in Replacement Collateral, certifying that the purchase price for the amount
of the investment in Replacement Collateral does not exceed the Fair Market Value of such Replacement Collateral;

 

(ii)         the
Company shall deliver an Officers’ Certificate to the Collateral Agent and the Trustee certifying compliance with the provisions
of this Indenture and requesting the release of such certified purchase price to the Company (or the applicable Restricted Subsidiary),
free of the Lien of the Collateral Documents; and

 

(iii)        the
Company shall take such actions, at its sole expense, as may be required to permit the Collateral Agent, pursuant to the applicable
Collateral Document, to release such Net Proceeds, together with any interest thereon, from the Lien of the applicable Collateral
Document and to ensure that the Collateral Agent has, from the date of such purchase or investment, a first-priority Lien on such
Replacement Collateral pursuant to appropriate Collateral Documents.

 

Notwithstanding anything to the contrary
in the foregoing, pending application of such consideration to acquire Replacement Collateral or restore the relevant Collateral
in an Event of Loss, any consideration received in connection with a Collateral Asset Sale, an Event of Loss or an investment in
Replacement Collateral shall be paid directly by the purchaser thereof to the Collateral Agent or otherwise constitute Collateral
subject to a first-priority lien in form and substance satisfactory to the Collateral Agent.

 

(e)          Asset
Sales Offer. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph of Section
4.10(a) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds
exceeds U.S.$5,000,000, within five days thereof, the Company shall make an Asset Sale Offer to all Holders of Notes and all holders
of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture
with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase
the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds
at the offer price specified in the next sentence. The offer price in any Asset Sale Offer will be equal to 100% of the principal
amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain
after consummation of an Asset Sale Offer, 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 pari passu Indebtedness tendered into such Asset Sale
Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Company shall select such other pari
passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds
will be reset at zero.

 

    	55

    	 

    

  

The Company shall comply with the requirements
of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations
are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of
any securities laws or regulations conflict with the provisions of Section 3.09 hereof or this Section 4.10, the Company shall
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section
3.09 hereof or this Section 4.10 by virtue of such compliance.

 

4.11.         Transactions
with Affiliates. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly,
make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property
or assets from, or enter into or make or amend or permit to exist any transaction, contract, agreement, understanding, loan, advance
or guarantee with, or for the benefit of, any Affiliate of the Company (each an “Affiliate Transaction”),
unless:

 

(i)          the
Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that
would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and

 

(ii)         

 

(A)         with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
U.S.$2,500,000, (1) the terms of the Affiliate Transaction are set forth in writing; (2) a majority of the disinterested members
of the Board of Directors of the Company have determined in good faith that such Affiliate Transaction complies with this covenant
and have approved such Affiliate Transaction; and (3) the Company delivers to the Trustee a resolution of the Board of Directors
of the Company set forth in an Officers’ Certificate evidencing the fulfillment of the condition set out in clause (ii)(A)(2);
and

 

(B)         with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
U.S.$6,000,000, in addition to the conditions set out in clause (ii)(A), the Company delivers to the Trustee a written opinion
to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and its Restricted Subsidiaries
issued by an investment banking firm of national standing.

 

    	56

    	 

    

 

(b)          The
following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject
to the provisions of Section 4.11(a) hereof:

 

(i)          any
reasonable and customary employment agreement, employee benefit plan, officer or director indemnification agreement or any similar
arrangement entered into by the Company or any of its Restricted Subsidiaries and approved by the Board of Directors;

 

(ii)         transactions
exclusively between or among the Company and/or any of its Restricted Subsidiaries or exclusively between or among such Restricted
Subsidiaries;

 

(iii)        payment
of reasonable directors’ fees to directors of the Company and its Restricted Subsidiaries who are not otherwise Affiliates
of the Company as determined in good faith by the Company’s Board of Directors;

 

(iv)         any
issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company;

 

(v)          Restricted
Payments that do not violate Section 4.07 hereof;

 

(vi)         loans
or advances to employees in the ordinary course of business and in accordance with the past practices of the Company or its Restricted
Subsidiaries, but in any event not to exceed U.S.$500,000 in the aggregate at any time outstanding;

 

(vii)        transactions
with a Person that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary,
an Equity Interest in, or controls, such Person and no Affiliate of the Company (other than a Restricted Subsidiary thereof) owns
any Equity Interests in, or controls, such Person except through their ownership of the Company; and

 

(viii)      customary
and reasonable transactions in connection with a Permitted Securitization, including Standard Securitization Undertakings.

 

4.12.         Liens.
The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume
or suffer to exist any Lien of any kind on any asset or property of any character now owned or hereafter acquired by the Company
or any of its Restricted Subsidiaries or any proceeds, income or profits therefrom, or assign or convey any right to receive income
therefrom, except Permitted Liens.

 

4.13.         Business
Activities. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, engage, directly or indirectly,
in any business other than Permitted Businesses.

 

4.14.         Corporate
Existence. Subject to Article V hereof, the Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect:

 

    	57

    	 

    

 

(a)          its
corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and

 

(b)          the
rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence
of any of its Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders of the Notes.

 

4.15.         Offer
to Repurchase Upon Change of Control. (a) Upon the occurrence of a Change of Control, the Company shall make an offer (a “Change
of Control Offer”) to each Holder to repurchase all or any
part (equal to U.S.$150,000 or integral multiples of U.S.$1.00 above U.S.$150,000) of that Holder’s Notes at a purchase price
in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional
Amounts, if any, on the Notes repurchased to the date of purchase, subject to the rights of Holders of Notes on the relevant record
date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within
10 days following the date on which a Change of Control occurs, the Company shall mail, by first-class mail, a notice to each Holder,
with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control and stating:

 

(i)          that
the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

 

(ii)         the
purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice
is mailed (the “Change of Control Payment Date”);

 

(iii)        that
any Note not tendered will continue to accrue interest;

 

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

 

(v)          that
Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with
the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer,
to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the
Change of Control Payment Date;

 

(vi)         that
Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second
Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election
to have the Notes purchased; and

 

    	58

    	 

    

 

(vii)        that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered, which unpurchased portion must be equal to a minimum of U.S.$150,000 in principal amount or an integral
multiple of U.S.$1.00 above U.S.$150,000.

 

The Company shall comply with the requirements
of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations
are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions
of any securities laws or regulations conflict with the provisions of Section 4.15 hereof, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.15 by virtue of such
compliance.

 

(b)          On
the Change of Control Payment Date, the Company shall, to the extent lawful:

 

(i)          accept
for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

 

(ii)         deposit
with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered;
and

 

(iii)        deliver
or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate
principal amount of Notes or portions of Notes being purchased by the Company.

 

The Paying Agent will promptly mail or,
if sent through DTC, send in accordance with DTC’s applicable procedures (but in any event not later than five Business Days
after the Change of Control Payment Date), to each Holder of Notes properly tendered the Change of Control Payment for such Notes,
and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company shall publicly announce the results
of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

 

(c)          Notwithstanding
anything to the contrary in this Section 4.15, the Company shall not be required to make a Change of
Control Offer upon a Change of Control (i) if a third party makes the Change of Control Offer in the manner, at the times and otherwise
in compliance with the requirements set forth in this Section 4.15 hereof and purchases all Notes properly tendered and not withdrawn
under the Change of Control Offer, or (ii) if a notice of redemption is given pursuant to Section 3.07 hereof and the redemption
described therein is effected in accordance therewith.

 

4.16.         Additional
Note Guarantees; Additional Security. (a) If the Company or any of its Restricted Subsidiaries acquires or creates any direct
or indirect Subsidiary after the date of this Indenture (a “New Subsidiary”), then the Company or such Restricted
Subsidiary shall, within ten Business Days after such formation or acquisition, cause such New Subsidiary to:

 

    	59

    	 

    

 

(a)          become
a Guarantor and deliver to the Trustee a duly executed supplemental indenture and an Opinion of Counsel,
each of which shall be in form and substance satisfactory to the Trustee, pursuant to which such New Subsidiary will unconditionally
and irrevocably guarantee the Company’s obligations under the Notes, provided that any New Subsidiary that is designated
as an Unrestricted Subsidiary need not become a Guarantor until five Business Days after as it ceases
to be an Unrestricted Subsidiary; it being understood that such New Subsidiary shall take all required corporate
actions and obtain all necessary authorizations to effect the valid execution and delivery of such supplemental indenture and any
related documents; and

 

(b)          duly
execute and deliver to the Trustee and the Collateral Agent an Intercompany Subordination and Credit Agreement Supplement and an
Intercompany Trust Agreement Supplement; it being understood that such New Subsidiary shall take all required corporate
actions and obtain all necessary authorizations to effect the valid execution and delivery of such Intercompany
Subordination and Credit Agreement Supplement and Intercompany Trust Agreement Supplement.

 

4.17.         Designation
of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary
to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an
Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted
Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation
and will reduce the amount available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition
of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted
at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors
of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause
a Default.

 

Any designation of a Subsidiary of the Company
as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the
Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied
with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail
to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for
purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of
the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof,
the Company shall be in default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence
of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation will only be permitted if: (1) such Indebtedness is permitted under Section 4.09 hereof, and if such Indebtedness is
being permitted pursuant to Section 4.09(a), the Leverage Ratio set forth in Section 4.09(a) being calculated on a pro forma basis
as if such designation had occurred at the beginning of the two-quarter Reference Period; and (2) no Default or Event of Default
would be in existence following such designation.

 

    	60

    	 

    

 

4.18.         Listing.
The Company shall use its best efforts to obtain and maintain listing of the Notes on the official list of the Luxembourg Stock
Exchange and to maintain the Notes admitted to trading on the Euro MTF, the alternative market of the Luxembourg Stock Exchange;
provided, however, that if the Company is unable to list the Notes on the Euro MTF, or if the Company is unable maintain
its listing on the Euro MTF, it will use its best efforts prior to the delisting of the Notes to list and maintain a listing of
the Notes on another internationally recognized stock exchange. In the event that a Restricted Subsidiary provides a Guarantee
or is released from its obligations under a Guarantee at a time when the Notes are listed on the Euro MTF, the Company shall, to
the extent required by the rules of the Luxembourg Stock Exchange, publish notice of the granting or release of such Restricted
Subsidiary Guarantee in the d’Wort, send a copy of such notice to the Luxembourg Stock Exchange and, in the case of
the granting of a new Restricted Subsidiary Guarantee, deposit a copy of the Restricted Subsidiary Guarantee with the Luxembourg
Stock Exchange and the Luxembourg Sub-Paying Agent.

 

4.19.         Withholding
Taxes. All payments under or in respect of the Notes or any Note Guarantee shall be made free and clear of, and without withholding
or deduction for or on account of, any present or future taxes, duties, levies, imposts, assessments or governmental charges (including
penalties, interest and additions related thereto) (collectively, “Taxes”) of whatever nature imposed, levied,
collected, withheld or assessed unless such withholding or deduction is required by law. In the event of any such withholding or
deduction imposed or levied by a Tax Jurisdiction is required to be made from any payments under or
with respect to the Notes or any Note Guarantee, the Company or the relevant Guarantor, as applicable, shall pay to Holders of
the Notes such additional amounts (“Additional Amounts”) as will result
in the net payment to such Holder (including Additional Amounts) of the amount that would otherwise have been receivable by such
Holder in the absence of such withholding or deduction, except that no such Additional Amounts shall be payable with respect to:

 

(a)          any
Taxes that would not have been so withheld or deducted but for the Holder or Beneficial Owner of the Notes having a present or
former connection to the relevant Tax Jurisdiction (including having a permanent establishment for tax purposes in such Tax Jurisdiction,
being a citizen or resident or national of, incorporated in or carrying on a business, in the relevant Tax Jurisdiction in which
such Taxes are imposed) other than the mere receipt of payments in respect of the Notes or any Note Guarantee, the mere holding
or ownership of such Note or beneficial interest in the Note or the exercise of any rights under the
Notes or this Indenture;

 

(b)          where
presentation is required for payment on a Note, any Taxes that would not have been so withheld or deducted if the Note had been
presented for payment within 30 days after the Relevant Date, except to the extent that the Holder would have been entitled to
Additional Amounts had the Note been presented on any day during such 30 day period and there were no additional withholdings or
deductions as a result of such late presentment;

 

(c)          any
Taxes that would not have been so withheld or deducted but for the failure by the Holder or the Beneficial Owner of the Note or
any payment in respect of such Note, after written request made to that Holder or Beneficial Owner at least 60 days before any
such withholding or deduction would be payable, by the Company or the relevant Guarantor, the Trustee or the Paying Agent, as applicable,
to comply with any certification, identification, information, documentation or other similar reporting requirement concerning
its nationality, residence, identity or connection with the relevant Tax Jurisdiction, which is required or imposed by a statute,
regulation or administrative practice of the relevant Tax Jurisdiction as a precondition to exemption from all or part of such
Taxes;

 

    	61

    	 

    

 

(d)          any
estate, inheritance, gift, sales, transfer, personal property or similar Taxes imposed with respect to any Note;

 

(e)          any
Taxes payable other than by withholding or deduction;

 

(f)          any
withholding or deduction imposed on a payment to an individual that is required to be made pursuant to the European Union Directive
on the taxation of savings income (the “Directive”) implementing the conclusions of the European Council
of Economic and Finance Ministers (ECOFIN) meeting on June 3, 2003, or any law implementing or complying with, or introduced in
order to conform to, such Directive;

 

(g)          any
Taxes imposed in connection with a Note presented for payment (where presentation is required) by or on behalf of a Holder or Beneficial
Owner thereof who would have been able to avoid such tax by presenting the relevant Note to another paying agent; or

 

(h)          any
combination of (a) through (g) above.

 

Notwithstanding the foregoing, the limitations
on the Company’s (or any relevant Guarantor’s, as applicable) obligation to pay Additional Amounts set forth in clauses
(c) and (h) above shall not apply if (i) the provision of information, documentation or other evidence described in such clauses
(c) and (h) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or
Beneficial Owner of a Note (taking into account any relevant differences between U.S. and Mexican law rules, regulations or administrative
practice) than comparable information or other reporting requirements imposed under U.S. tax law, regulation
and administrative practice as of the Issue Date (such as IRS Forms W-8, W-8BEN and W-9) or (ii) Article 195, Section II of the
Mexican Income Tax Law, or a substantially similar successor of such provision is in effect, unless the provision of the information,
documentation or other evidence described in clauses (c) and (h) is expressly required by statute, regulation, or official administrative
practice of general application in order to apply Article 195, Section II of the Mexican Income Tax Law (or a substantially similar
successor of such rule), the Company cannot obtain such information, documentation or other evidence on its own through reasonable
diligence and the Company otherwise would meet the requirements for application of Article 195, Section II of the Mexican Income
Tax Law. In addition, such clauses (c) and (h) shall not be construed to require a non-Mexican pension or retirement fund or a
non-Mexican financial institution or another Holder to register with the Ministry of Finance and Public Credit (Servicio de
Administración Tributaria) for the purpose of establishing eligibility for an exemption from or reduction of Mexican
withholding tax or to require that a Holder or Beneficial Owner certify or provide information concerning whether it is or is not
a tax-exempt pension or retirement fund.

 

    	62

    	 

    

 

 

If the Directive imposes taxes upon Notes,
the Company shall use commercially reasonable efforts to maintain a paying agent with a specified office in a member state of the
European Union that will not be obligated to withhold or deduct tax pursuant to the Directive or any law implementing or complying
with, or introduced in order to conform to, the Directive.

 

References to principal, interest or any
other amount payable on or in respect of any Note shall be deemed also to refer to any Additional Amounts which may be payable
as set forth in this Indenture or in the Notes to the extent that Additional Amounts are, were or would be payable in respect thereof.

 

At least ten Business Days prior to the
first interest payment date (and at least ten Business Days prior to each succeeding interest payment date if there has been any
change with respect to the matters set forth in the below mentioned Officers’ Certificate), the Company or the relevant Guarantor,
as applicable, will furnish to the Trustee and the Paying Agent an Officers’ Certificate instructing the Trustee and the
Paying Agent whether payments of principal of or interest on the Notes due on such interest payment date shall be made without
deduction or withholding for or on account of any Taxes by the Tax Jurisdictions (other than the jurisdiction where the Trustee
is located or organized). If any such deduction or withholding shall be required, at least 20 days prior to such interest payment
date (unless the obligation to pay Additional Amounts arises after the 20th day prior to the payment date, in which case the Company
or the relevant Guarantor shall notify the Trustee and the Paying Agent promptly thereafter), the Company, or the relevant Guarantor,
as applicable, will furnish the Trustee and the Paying Agent with an Officers’ Certificate that specifies the amount, if
any, required to be withheld on such payment to Holders of the Notes. If the Company or any Guarantor is obligated to pay Additional
Amounts with respect to such payment, the Officers’ Certificate must also set forth any other information reasonably necessary
to enable the Paying Agent to pay Additional Amounts to the Holders on the relevant payment date. For these purposes, any Officers’
Certificate required by this Indenture to be provided to the Trustee and the Paying Agent shall be deemed to be duly provided if
telecopied to the Trustee and the Paying Agent.

 

The Company or the relevant Guarantor, as
applicable, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the
relevant tax authority in accordance with applicable law. The Company or the relevant Guarantor, as applicable, will obtain official
receipts from each tax authority evidencing the payment of any Taxes so deducted or withheld, or, if such receipts are not obtainable,
such other documentation reasonably acceptable to the Trustee. The Company, or the relevant Guarantor, as applicable, shall furnish
to the Trustee the official receipts (or a certified copy of the official receipts or other such documentation, as applicable)
evidencing payment of Taxes. The Company or the relevant Guarantor, as applicable, will attach to each certified copy or other
such documentation, as applicable, a certificate stating (x) that the amount of such Tax evidenced by the certified copy was paid
in connection with payments under or with respect to the Notes then outstanding upon which such Taxes were due and (y) the amount
of such withholding tax paid per U.S.$1.00 of principal amount of the Notes. Copies of such receipts or other such documentation,
as applicable, shall be made available to Holders of the Notes upon written request.

 

The Company and the relevant Guarantor,
as applicable, shall promptly pay when due, and indemnify the Holder for, any present or future stamp, issue, registration, court
and/or documentary taxes, and/or any other excise taxes, similar charges or similar levies imposed by the Tax Jurisdictions on
the execution, delivery, registration or enforcement of any of the Notes, this Indenture, any Guarantee or any other document or
instrument referred to herein or therein.

 

    	63

    	 

    

 

The Company and any relevant Guarantor,
as applicable, will indemnify and hold harmless each Holder of Notes and, upon written request of any Holder of Notes, reimburse
each such Holder, for the amount of:

 

(1)         any
Taxes (other than Taxes excluded under clauses (a) through (h)) levied or imposed and paid by such Holder as a result of payments
made on or with respect to the Notes; provided that reasonable supporting documentation is provided; and

 

(2)         any
Taxes (other than Taxes excluded under clauses (a) through (h)) levied or imposed with respect to any reimbursement under the foregoing
clause (1), so that the net amount received by such Holder after such reimbursement will not be less than the net amount the Holder
would have received if Taxes (other than Taxes excluded under clauses (a) through (h)) on such reimbursement had not been imposed.

 

Any payments made pursuant to the preceding
sentence will be treated as Additional Amounts for all relevant purposes.

 

4.20.         Sale
and Leaseback Transactions. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, enter into any Sale and Leaseback Transaction with respect to any property or assets unless:

 

(a)             the
Company or the Restricted Subsidiary, as applicable, would be entitled to:

 

(i)          incur
Indebtedness in an amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction pursuant to Section
4.09; and

 

(ii)         create
a Lien on such property or assets securing such Attributable Debt pursuant to Section 4.12.

 

in which case, the corresponding Indebtedness and Lien will
be deemed incurred pursuant to those provisions, and

 

(b)             the
Company complies with Section 4.10 hereof in respect of such transaction.

 

4.21.         Limitation
on the Sale or Issuance of Capital Stock of Restricted Subsidiaries. The Company:

 

(a)             shall
not, and shall not permit any Restricted Subsidiary to, sell, lease, transfer or otherwise dispose of any Capital Stock of any
Restricted Subsidiary to any Person (other than the Company or a Wholly-Owned Restricted Subsidiary); and

 

(b)            shall
not permit any Restricted Subsidiary to issue any of its Capital Stock (other than, if necessary, shares of its Capital Stock constituting
directors’ or other legally required qualifying shares) to any Person (other than to the Company or a Wholly-Owned Restricted
Subsidiary), unless:

 

    	64

    	 

    

 

(i)          immediately
after giving effect to such issuance, sale or other disposition, neither the Company nor any of its Subsidiaries own any Capital
Stock of such Restricted Subsidiary;

 

(ii)         immediately
after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary and any Investment in such Person remaining after giving effect thereto would have been permitted to be made under Section
4.07 if made on the date of such issuance, sale or other disposition; or

 

(iii)        immediately
after giving effect to such issuance, sale or other disposition, such Restricted Subsidiary would continue
to constitute a Restricted Subsidiary and the Company or such Restricted Subsidiary applies the Net Proceeds of any such sale in
accordance with Section 4.10 hereof.

 

4.22.         No
Impairment of Security Interests. Neither the Company nor any of its Restricted Subsidiaries will be permitted to take any
action, or knowingly or negligently omit to take any action, which action or omission might or would have the result of materially
impairing the security interest with respect to the Collateral for the benefit of the Collateral Agent, the Trustee and the Holders
of the Notes, including the failure to obtain any required approval or any material defect in the creation, perfection or first-priority
status of any Lien granted pursuant to the Collateral Documents. The Company shall cause the Restricted Subsidiaries to comply
with their respective obligations under the Collateral Documents. The Company shall not amend, modify or supplement, or permit
or consent to any amendment, modification or supplement of, the Collateral Documents in any way that would be adverse to the Holders
of the Notes in any material respect, except as described under Article X hereof or as permitted under Article IX hereof.

 

4.23.         Limitation
on Intercompany Indebtedness.

 

(i)             The
Company shall, and shall cause its Subsidiaries, to cause all existing and future Intercompany Indebtedness (other than Ordinary
Course Intercompany Indebtedness) to be subordinated to the Notes pursuant to the terms of the Intercompany Subordination and Credit
Agreement and the Intercompany Trust Agreement, the terms of which, among other things, will provide that (i) no cash payments
will be permitted to be made in respect of such Intercompany Indebtedness while any of the Notes remain outstanding and (ii) all
such Intercompany Indebtedness will be subordinated to the Notes in liquidation and in right of payment.

 

(ii)             All
existing and future Ordinary Course Intercompany Indebtedness will be incurred or deemed incurred pursuant to, and in accordance
with the terms of, the Intercompany Subordination and Credit Agreement, the terms of which, among other things, will provide that
(i) the Company and/or its Subsidiaries will be permitted to incur additional Ordinary Course Intercompany Indebtedness and make
and collect payments in respect of such Ordinary Course Intercompany Indebtedness so long as such Ordinary Course Intercompany
Indebtedness is incurred, and such payments are made or collected, in the ordinary course of business consistent with past practice
and (ii) all such Ordinary Course Intercompany Indebtedness will be subordinated to the Notes in liquidation and in right of payment
(subject to the preceding clause (i)).

  

    	65

    	 

    

 

(iii)        During
the pendency of any proceeding filed by or against the Company or any of its Subsidiaries seeking relief as debtor, or seeking
to adjudicate the Company or any of its Subsidiaries as bankrupt or insolvent, or seeking reorganization, arrangement, adjustment
or composition of the Company or any of its Subsidiaries or its debts under any law relating to bankruptcy, insolvency, reorganization,
concurso mercantil, quiebra, or relief of debtors, or seeking appointment of a receiver, trustee, assignee, custodian, liquidator
or visitador, conciliador or síndico or any other similar official for the Company or any of its Subsidiaries
or for any substantial part of their property, the Company shall, and shall cause each of its Subsidiaries to, vote any claims
that the Company or any Subsidiary of the Company might have based on Intercompany Indebtedness in the same manner as the majority
of the unaffiliated third-party creditors of the Company and its Subsidiaries pursuant to the terms of the Intercompany Subordination
and Credit Agreement and the Intercompany Trust Agreement.

 

(iv)        Neither
the Company nor any of its Subsidiaries will (i) enter into or maintain any Intercompany Indebtedness other than Intercompany
Indebtedness under the Intercompany Subordination and Credit Agreement in accordance with the
terms of this Section 4.23, or (ii) amend or waive any part of the documentation with
respect to Intercompany Indebtedness in any way that would result in (x) a violation of this Indenture or the Collateral Documents
or (y) a change of any kind in the provisions of such documentation relating to the subordination of the Intercompany Indebtedness.

 

(v)         Upon
the occurrence and during the continuation of an Event of Default, the Company shall not make any payment to any Subsidiary pursuant
to the terms of any Intercompany Indebtedness and shall not take any action that could cause or result in such payment being made.

 

4.24.     Excess
Capital Contribution Offer. (a) The Company shall use 50% of any Excess Capital Contribution greater than U.S.$5,000,000 (the
“Excess Capital Contribution Amount”) to make an offer to each Holder of Notes to repurchase such Holder’s
Notes at the offer price specified in the next sentence (an “Excess Capital Contribution Offer”). The offer
price in any Excess Capital Contribution Offer will be equal to 85% of the principal amount of the Notes plus accrued and unpaid
interest and Additional Amounts, if any, on the Notes repurchased to the date of purchase, and shall be payable by the Company
in cash. If the aggregate principal amount of Notes tendered into such Excess Capital Contribution Offer, taking into account the
offer price of 85% of the principal amount of the Notes, exceeds the Excess Capital Contribution Amount, the Company shall select
the Notes to be purchased in accordance with the selection procedures set forth in Section 3.02 hereof. Any portion of the Excess
Capital Contribution that remains after consummation of an Excess Capital Contribution Offer may be used by the Company for any
purpose not otherwise prohibited by this Indenture.

  

    	66

    	 

    

 

(b)          Within
10 days following the date on which the Company has received all Excess Capital Contributions to be made in connection with the
Purchaser’s Capital Contribution (and the total Excess Capital Contributions exceed U.S.$5,000,000), the Company shall mail,
by first-class mail or, if sent through DTC, send in accordance with DTC’s applicable procedures, a written notice to each
Holder, with a copy to the Trustee, stating the Excess Capital Contribution Amount and offering to repurchase Notes on the Excess
Capital Contribution payment date specified in such notice, which date will be no earlier than 30 days and no later than 60 days
from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice.

 

(c)          The
Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder
to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Excess Capital
Contribution Offer. To the extent that the provisions of any securities laws or regulations conflict with the Excess Capital Contribution

for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or
any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture,
if that default:

 

(i)          is
caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace
period provided in such Indebtedness on the date of such default (a “Payment Default”); or

 

(ii)         results
in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness,

of which has been so accelerated, aggregates U.S.$10,000,000 or more;

 

(f)          failure

of 60 days;

 

(g)          except
as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable

the Company that, taken together, would constitute a Significant Subsidiary; or

 

(iii)        orders
the liquidation of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; and

 

(y)  such order or decree
remains unstayed and in effect for 60 consecutive days.

 

6.02.      Acceleration.
In the case of an Event of Default specified in clause (h) or (i) of Section 6.01 hereof, with respect to the Company, any
Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that,
taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without
further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in
aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Upon any
such declaration, the Notes shall become due and payable immediately.

 

The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration
and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except
non-payment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived
and the Company has paid or deposited, or caused to be paid or deposited, with the Trustee a sum sufficient to pay all sums paid
or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel.

 

6.03.     Other
Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment
of principal, premium if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

 

The Trustee may maintain a proceeding even
if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or
any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

  

    	70

    	 

    

 

6.04.     Waiver
of Defaults. Subject to Section 6.02, Holders of not less than a majority in aggregate principal amount of the then outstanding
Notes by written notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if
any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders
of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its
consequences, including any related payment default that resulted from such acceleration. Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

 

6.05.     Control
by Majority. Holders of a majority in aggregate principal amount of the then outstanding Notes may, in writing, direct the
time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust
or power conferred on it. However, the Trustee may, in good faith as determined by a Responsible Officer of the Trustee, refuse
to follow any direction that conflicts with applicable law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

 

6.06.     Limitation
on Suits. A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

 

(a)          such
Holder gives to the Trustee written notice that an Event of Default is continuing;

 

(b)          Holders
of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the
remedy;

 

(c)          such
Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any
loss, liability or expense;

 

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

 

(e)          during
such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a
direction inconsistent with such request.

 

A Holder of a
Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference
or priority over another Holder of a Note.

 

6.07.         Rights
of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a
Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective
due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any
such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

 

    	71

    	 

    

 

6.08.         Collection
Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal
of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest
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.

 

6.09.         Trustee
May File Proofs of Claim. The Trustee is authorized to 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 all other amounts due to the Trustee pursuant to Section 7.07 hereof) and
the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any custodian 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 hereof. To the extent
that the payment of any such reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any
reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under
any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting
the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding,
in each case absent express authorization from such Holder. Notwithstanding the foregoing or any proof of claim that may
have been filed by the Trustee, the parties hereto acknowledge and agree that the Holder or Beneficial Owner shall have the right
to participate individually in any receivership, insolvency, liquidation, bankruptcy, reorganization, concurso mercantil,
quiebra, arrangement, adjustment, composition, or other judicial proceeding relative to the Company or any Guarantor or
the property of the Company or such Guarantor or their creditors, to the extent such participation is permissible under applicable
law, and to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same
in accordance with this Indenture.

 

6.10.         Priorities.
If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order:

 

First: to the Trustee, its
agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities
incurred, and all advances made, by the Trustee, and the costs and expenses of collection;

  

    	72

    	 

    

 

Second: to Holders of Notes
for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of
any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and

 

Third: to the Company or
to such party as a court of competent jurisdiction shall direct.

 

The Trustee may
fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

 

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

requirements of this Indenture but need not confirm or investigate
the accuracy of mathematical calculations or other facts stated therein.

  

    	73

no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind

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 any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the
event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, if required, apply to
the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do
the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture,
the Notes, the Note Guarantees or the Collateral Documents, it shall not be accountable for the Company’s use of the proceeds

not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the
sale of the Notes or pursuant to this Indenture other than its certificate of authentication and
such statements and recitals shall be taken as those of the Company.

 

7.05.         Notice
of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer
of the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it
occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on, any Note,
or a default pursuant to clause (e) or (f) of Section 6.01, the Trustee shall
be protected in withholding the notice if and so long as a Responsible Officer of the Trustee in good faith determines that
withholding the notice is in the interests of the Holders of the Notes.

 

7.06.         Reports
by Trustee to Holders of the Notes. (a) Within 60 days after each June 15 beginning with the June 15 following the date of
this Indenture, and for so long as Notes remain outstanding, the Trustee shall transmit to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred
within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA §
313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

 

(b)            A
copy of each report at the time of its transmission to the Holders of Notes will be mailed by the Trustee to the Company and filed
by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company
shall promptly notify the Trustee when the Notes are listed on any stock exchange and of any delisting thereof.

 

7.07.         Compensation
and Indemnity. (a) The Company and the Guarantors will jointly and severally pay to the Trustee from time to time compensation
as agreed in writing between the Company and the Trustee from time

by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for
all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such
expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

  

    	76

    	 

    

 

(b)          The
Company and the Guarantors will jointly and severally indemnify the Trustee and
its agents against any and all losses, damages, claims liabilities
or expenses (including any environmental liabilities) incurred by it arising out of or in connection with the acceptance or administration
of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors
(including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder
or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except
to the extent any such loss, damage, claim liability or expense
may be attributable to its negligence or willful misconduct. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company or any of the Guarantors of
their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee shall cooperate in the defense.
The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. Neither the Company
nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld. In the
event that the Company does not accept the defense of a claim as provided above, the Trustee shall have the full right to defend
against such claim in its sole discretion, and pursue its rights hereunder.

 

(c)          The
obligations of the Company and the Guarantors under this Section 7.07 will survive the resignation or removal of the Trustee and
the satisfaction and discharge of this Indenture.

 

(d)          To
secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee shall have a Lien prior
to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest
on particular Notes. Such Lien will survive the resignation or removal of the Trustee and the satisfaction and discharge of this
Indenture.

 

(e)          When
the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law.

 

(f)          The
Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable.

 

7.08.      Replacement
of Trustee. (a) A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only
upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

 

(b)          The
Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders
of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and
the Company in writing. The Company may remove the Trustee if:

(iv)        the

(c)          If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly, but
in no event later than 45 days after such resignation or removal, appoint a successor Trustee. Within one year after the successor
Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor
Trustee to replace the successor Trustee appointed by the Company.

 

(d)          If
a successor Trustee does not take office within 45 days after the retiring Trustee resigns or is removed, the retiring Trustee,
the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may, at the expense of
the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee.

 

(e)          If
the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10
hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

 

(f)          A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon,
the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers
and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring
Trustee.

 

7.09.      Successor

Article
VIII

Legal Defeasance and Covenant Defeasance

 

8.01.      Option
to Effect Legal Defeasance or Covenant Defeasance. The Company may at any time, at the option of its Board of Directors evidenced
by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all
outstanding Notes upon compliance with the conditions set forth below in this Article VIII.

 

8.02.    Legal
Defeasance and Discharge. Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from their obligations with respect to all outstanding Notes and all obligations of the Guarantors
discharged with respect to their Note Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal
Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid
and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees),
which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections
of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such Notes,
the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

 

(a)          the
rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, and
any Additional Amounts that may be due and payable, if any, on, such Notes when such payments are due from the trust referred to
in Section 8.04 hereof;

 

(b)          the
Company’s obligations with respect to such Notes under Article II and Section 4.02 hereof;

 

(c)          the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations
in connection therewith; and

 

(d)          this
Article VIII.

 

Subject to compliance with this Article
VIII, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section
8.03 hereof

 

    	79

    	 

    

 

8.03.      Covenant
Defeasance. Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the
Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released
from each of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16,
4.17, 4.20, and 4.21 hereof and clause (d) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the
conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the
Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes).
For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the
Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any
such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture
and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01
hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(c) and 6.01(d) hereof shall not constitute Events of Default.

federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

  

    	80

    	 

    

  

(c)          in
the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion
of Counsel in the United States reasonably acceptable to the Trustee confirming that the Beneficial Owners of the outstanding Notes
will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be

such Covenant Defeasance had not occurred;

 

(d)          the
Company must deliver to the Trustee an Opinion of Counsel in Mexico to the effect that (A) the Beneficial
Owners of the outstanding Notes will not recognize income, gain or loss for Mexican Tax purposes as a result of such deposit and
defeasance and will be subject to Mexican Taxes, in the same manner and at the same times as would have been the case if such deposit
and defeasance had not occurred, and (B) payments from the defeasance trust will be made free and clear of, and without withholding
or deduction for or on account of any present or future Taxes imposed, levied, collected, withheld or assessed by Mexico or any
political subdivision or governmental authority thereof or therein having power to Tax;

 

(d)          no
Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation
of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company
or any Guarantor is bound;

 

(e)          123
days pass after the deposit is made and during the 123-day period no Event of Default under clauses (h) or (i) of Section 6.01
occurs;

 

(f)          such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries
is bound;

 

(g)          the
Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders of Notes over the other creditors of the Company or with the intent of defeating, hindering, delaying
or defrauding any creditors of the Company or others;

(i)          the
Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance, as applicable, have been complied with.

  

    	81

    	 

    

  

8.05.      Deposited
Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money
and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect
of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and
this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting
as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect
of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required
by law.

 

The Company shall
pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against
the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding
Notes.

 

Notwithstanding
anything in this Article VIII to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or non-callable Government Securities held by it as provided in Section
8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount
thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 

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

 

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

Note:

cure any ambiguity, defect or inconsistency;

 

(b)          to
provide for uncertificated Notes in addition to or in place of certificated Notes;

comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

 

(f)          to
allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes;

 

(g)          to
conform the text of this Indenture to any provision of the “Description of Step-Up Senior Notes” exhibit to the Disclosure
Statement, to the extent that such provision in that “Description of Step-Up Senior Notes” was intended to be a verbatim
recitation of a provision of this Indenture or the Notes, as evidenced by an Officers’ Certificate;

 

(h)          to
provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date;

Upon the written
request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended
or supplemental indenture, and upon receipt by the Collateral Agent
and the Trustee of the documents described in Section 7.02 and
Section 9.05 hereof, the Trustee shall join with the Company and the Guarantors in the execution
of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate
agreements and stipulations that may be therein contained, but neither
the Trustee nor the Collateral Agent shall be obligated
to enter into such amended or supplemental indenture that affects its own rights, duties or immunities
under this Indenture or otherwise.

  

    	83

    	 

    

  

9.02.      With
Consent of Holders of Notes. Except as provided below in this Section 9.02, the Company, the Collateral Agent and the Trustee
may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10, 4.15 and 4.24 hereof) and the Notes
and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding
Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.04 and
6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal
of, premium, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded)
or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders
of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if
any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, the Notes).

the Collateral Agent of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee and
the Collateral Agent of the documents described in Section 7.02 and
Section 9.05 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental
indenture unless such amended or supplemental indenture directly affects the Trustee's
or the Collateral Agent’s own rights, duties or immunities under this Indenture or otherwise, in which case each of
the Trustee and the Collateral Agent may in its
discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

 

It is not be
necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it is sufficient if such consent approves the substance thereof.

 

After an amendment, supplement or
waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of Notes
affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice,
or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture
or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then
outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture
or the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under
this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

 

(i)          reduce
the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

  

    	84

    	 

    

 

(ii)         reduce
the principal of or change the fixed maturity of any Note or alter any of the provisions with respect to the redemption of the
Notes (except as provided above with respect to Sections 3.09, 4.10, 4.15 and 4.24 hereof);

 

(iii)        reduce
the rate of or change the time for payment of interest, including default interest, on any Note;

 

(iv)        waive
a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Notes (except a rescission
of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes
and a waiver of the payment default that resulted from such acceleration);

 

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

 

(vi)        make
any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive
payments of principal of, or interest or premium, if any, on the Notes;

 

(vii)       waive
a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10, 4.15 and 4.24 hereof);

 

(viii)      release
any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this
Indenture;

 

(ix)         make
any change in the ranking or priority of any Note that would adversely affect the Holders of the Notes in any material respect;

 

(x)          impair
the right of any Holder of the Notes to receive payment of principal of and interest on such Holder’s Notes on or after the
due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;

 

(xi)         make
any change in the provisions of this Indenture described under Section 3.10 or Section 4.19 hereof that adversely affects the rights
of any Holder in any material respect, or amend the terms of the Notes or this Indenture in a way that would result in the loss
of an exemption from any of the Taxes described hereunder;

 

(xii)        make
any change in the provisions of the Collateral Documents that would adversely affect the Holders of the Notes in any material respect;
or

 

(xiii)       make
any change in the preceding amendment and waiver provisions.

 

9.03.      Revocation
and Effect of Consents. (a) A consent to an amendment, supplement or waiver by a Holder a Note shall bind the Holder and every
subsequent Holder of the Note or portion of the Notes that evidences the same debt as the consenting Holder’s Note, even
if notation of the consent or waiver is not made on the Note. Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of
a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note.
However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives
written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every Holder.

  

    	85

    	 

    

 

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

 

9.04.     Notation
on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note
thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication
Order, authenticate new Notes that reflect the amendment, supplement or waiver.

 

Failure to make the appropriate notation
or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

 

9.05.     Trustee
and Collateral Agent to Sign Amendments, Etc. The Trustee and the
Collateral Agent, in each case, shall sign any amended or supplemental indenture authorized pursuant to this Article IX
if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee
or the Collateral Agent, as applicable. The Company may not sign an amended or supplemental indenture until the Board of
Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee
and the Collateral Agent shall be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying
upon, in addition to the documents required by Section 13.05 hereof, an Officers’'
Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted
by this Indenture and that such supplemental indenture (and any Notes
issued in connection therewith) is the legal, valid and binding obligation of the Company and the Guarantors, as applicable, enforceable
against the Company and the Guarantors, as applicable, in accordance with its terms.

assets which constitute telecommunication network, comprised of switches, fiber optic and copper networks, radio and electronic
equipment, computers and engineering equipment, transportation equipment and office furniture, as set forth on its consolidated
balance sheet under “Telephone Network Systems and Equipment”, in each case owned by the Company or any Restricted
Subsidiary on the Issue Date or acquired by the Company or any Restricted Subsidiary after the Issue Date and all proceeds in respect
of any of the foregoing (collectively, and together with any assets that may be pledged from time to time, the “Collateral”)
to secure the performance of the obligations of the Company and the Guarantors to the Holders, the Trustee and the
Collateral Agent under the Notes, the Note Guarantees, the Collateral Documents and this Indenture, according to the terms
hereunder or thereunder (including the obligations of the Guarantors under Article XI hereof), and (ii) the Company and its Restricted
Subsidiaries and the Collateral Agent for the benefit of the Holders shall have executed the Intercompany Subordination and Credit
Agreement and the Intercompany Trust Agreement and implemented such agreements in full with respect to all Intercompany Indebtedness.

 

(b)          Each
Holder, by its acceptance of a Note, consents and agrees to all of the terms of the Collateral Documents (including, without limitation,
the provisions providing for the foreclosure, exercise of remedies and release of the Collateral) as the same may be in effect
or may be amended from time to time in accordance with their terms, and authorizes and directs the Trustee and the Collateral Agent,
as applicable, to enter into the Collateral Documents and to perform or cause to be performed obligations and exercise rights thereunder
in accordance therewith.

 

(c)          Each
of the Company and the Guarantors shall use its reasonable best efforts to do or cause to be done all such acts and things as may
be required by the next sentence of this Section 10.01, to assure and confirm to the Collateral Agent and the Trustee the first-priority
Liens upon the Collateral contemplated hereby and any Collateral Documents or any part thereof, as from time to time constituted,
so as to render the same available for the security and benefit of this Indenture and of the Obligations secured hereby, according
to the intent and purposes herein expressed. Each of the Company and the Guarantors shall (i) enter into the Collateral Documents,
(ii) within ten Business Days of the Issue Date, take all necessary steps to duly file the Collateral Documents for registration
in each relevant public registry in Mexico and promptly deliver to the Trustee and the Collateral Agent a copy of the original
record of registration (constancia de inscripción) issued by the Mexican notary public, and (iii) take any and all
actions reasonably required to cause the Collateral Documents to create and maintain, as security for the Obligations of the Issuer
and the Guarantors under the Notes, the Note Guarantees, the Collateral Documents and hereunder, a valid and enforceable perfected
Lien in and on all of the Collateral, in favor of the Collateral Agent
for the ratable benefit of the Holders, first in priority to any and all Liens at any time granted upon the Collateral, in each
case, no later than 45 Business Days after the Issue Date and deliver to the Trustee and the Collateral Agent a copy of the notarial
instrument evidencing the registration of such Liens in each relevant public registry in Mexico. Each of the Trustee, the Company
and the Guarantors hereby acknowledge and agree that the Collateral Agent shall hold the Collateral for the ratable benefit of
the Holders and the Trustee pursuant and subject to the terms of the Collateral Documents. The Company and each Guarantor shall
(A) deliver to the Trustee and the Collateral Agent copies of all documents required under the Collateral Documents to assure and
confirm to the Trustee and the Collateral Agent that the security interests created in respect of the Collateral (or any part thereof)
under the Collateral Documents constitute security for the Indenture and the Notes as contemplated in this Indenture, and (B) perform
or cause their respective Subsidiaries to perform all such actions as may be required by the provisions of the Collateral Documents.
Neither the Collateral Agent nor the Trustee shall be responsible for
and neither of them make any representation as to the existence, genuineness, value or protection of any Collateral, or the legality,
effectiveness or sufficiency of any Collateral Document, or for the creation, perfection, priority, sufficiency or protection of
any liens securing the Notes. For the avoidance of doubt, nothing herein shall require the Collateral Agent or the Trustee to file
financing statements or continuation statements or local filings required by Mexican law or be responsible for perfecting or maintaining
the perfection of security interests purported to be created as described herein (except for the safe custody of any Collateral
in its possession and the accounting for moneys actually received by it hereunder or under any other Collateral Document) and such
responsibility shall be solely that of the Company.

  

    	87

    	 

    

 

10.02.   Use
of the Collateral. Subject to the terms and conditions of the Collateral Documents and this Indenture, the Company shall be
entitled, unless an Event of Default has occurred and is continuing and the Collateral Agent has given contrary instructions in

the Collateral (other than any amounts that are the proceeds of a Collateral Asset Sale or an Event of Loss relating to the Collateral),
to freely operate the Collateral, to replace the Collateral and to sell or otherwise dispose of Collateral (including, with respect
to cash constituting Collateral by virtue of being proceeds under any mortgage), and to collect, invest
and dispose of any income in respect of any Collateral, in each case in the ordinary course of the Company’s business.

 

10.03.   Determinations
Relating to Collateral. In the event (a) the Collateral Agent shall receive any written request from the Company for consent
or approval with respect to any matter or thing relating to the Collateral or the Company’s obligations with respect thereto
or (b) there shall be due to or from the Collateral Agent under the provisions of the Collateral Documents any material performance
or the delivery of any material instrument or (c) a Responsible Officer of the Collateral Agent shall become actually aware of
any material nonperformance by the Company or any Guarantor of any covenant or any material breach of any representation or warranty
of the Company or a Guarantor set forth in the Collateral Documents, then, in each such event, the Collateral Agent shall be entitled
to hire, at the sole reasonable cost and expense of the Company, experts, consultants, agents and attorneys to advise the Collateral
Agent on the manner in which the Collateral Agent should respond to such request or render any requested performance or response
to such nonperformance or breach.

 

10.04.   Suits
to Protect the Collateral. Subject in all respects to the terms and conditions of the Collateral Documents, the Collateral
Agent shall have power to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment
of the Collateral by any acts which may be unlawful or in violation of this Indenture, the Collateral Documents, and such suits
and proceedings as the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Holders
in the Collateral Documents and in the principal, interest, issues, profits, rents, revenues and other income arising therefrom,
including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative
or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid, if the enforcement of, or compliance
with, such enactment, rule or order would impair the security hereunder or under the Collateral Document, or be prejudicial to
the interests of the Holders, the Trustee or the Collateral Agent.

shall release the Liens in favor of it in any Collateral to be sold pursuant to a Collateral Asset Sale or, in the case of certain
obsolete or other assets, to be disposed of in a transaction not considered a Collateral Asset Sale pursuant to clause (i) of the
exclusion to the definition thereof; provided that such transaction shall be subject to the provisions under Section 4.10
hereof.

to the payment of all unpaid fees, expenses, reimbursements, indemnifications and advancements of the Collateral Agent and its
agents and counsel under the Collateral Documents and to the unpaid fees, expenses, reimbursements and indemnifications of the
Collateral Agent;

 

(ii)         second,

set forth in the Collateral Documents in all respects. The Company and each Guarantor consent to, and agree to be bound by, the

thereunder in accordance therewith.

 

10.08.   Collateral
Agent.  (a) At the direction of the Holders of the Notes, the Trustee shall appoint a collateral agent, which shall be authorized

Collateral Agent appointed by the Trustee as provided in Section 10.08(a) hereof shall be the secured party of record with respect
to the security interests created in respect of the Collateral under the Collateral Documents and shall hold such Collateral for
the benefit of the Holders of the Notes.

 

(c)          The

to be (or not to be) suffered or omitted by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment,
expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Collateral

party hereto.

duties of the Collateral Agent shall be mechanical and administrative in nature. The Collateral Agent shall not have, by reason
hereof or any of the Collateral Documents, a fiduciary relationship with any Holder, the Company, any Guarantor or any other Person,
and nothing herein or in any of the Collateral Documents, inferred or implied, is intended to or shall be so construed as to impose
upon the Collateral Agent any duties, responsibilities or obligations in respect hereof or of any of the Collateral Documents,
except as expressly set forth herein or therein.

 

10.09.   Release
of Liens in Respect of the Notes. The Collateral Agent’s priority Liens upon the Collateral shall no longer secure the
Notes outstanding under this Indenture, the Note Guarantees or any other Obligations under this Indenture, and the right of the
Holders of the Notes and such Obligations to the benefits and proceeds of the Collateral Agent’s priority Liens on the Collateral
shall terminate and be discharged, in which case the Collateral Agent shall sign and permit the Company to file all required documents

Article
XI

Note Guarantees

 

11.01.  Guarantee.
(a) Subject to this Article XI, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder
of a Note authenticated and delivered by the Trustee and to the Trustee and 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:

 

(i)          the
principal of, premium and Additional Amounts, if any, and interest on, the Notes will be promptly paid in full when due, whether
at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest and premium and Additional
Amounts 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

 

(ii)         in
case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration
or otherwise.

 

Failing payment when due of any amount so
guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay
the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

 

(b)          The
Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability
of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes
with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each 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 covenant
that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this
Indenture.

  

    	92

    	 

    

 

(c)          If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the
Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

 

(d)          Each
Guarantor agrees that it 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 Guarantor further agrees that, as between the
Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article VI hereof for the purposes of this Note Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed
hereby, and (ii) in the event of any declaration of acceleration of such obligations as provided in Article VI hereof, such obligations
(whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee.
The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does
not impair the rights of the Holders under the Note Guarantee.

 

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

 

11.03.   Execution
and Delivery of Note Guarantee. To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees
that a notation of such Note Guarantee substantially in the form attached as Exhibit B hereto will be endorsed by an Officer
of such Guarantor by manual or facsimile signature on each Note authenticated and delivered by the Trustee in accordance with this
Indenture and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

 

Each Guarantor
hereby agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force
and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

 

If an Officer
whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates
the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

  

    	93

    	 

    

 

The delivery
of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery
of the Note Guarantee set forth in this Indenture on behalf of the Guarantors.

 

In the event
that the Company or any of its Restricted Subsidiaries creates or acquires any Subsidiary after
the date of this Indenture, if required by Section 4.16 hereof, the Company shall cause such Restricted Subsidiary to comply with
the provisions of Section 4.16 hereof and this Article XI, to the extent applicable.

 

11.04.   Guarantors
May Consolidate, Etc., on Certain Terms. Except as otherwise provided in Section 11.05 hereof, no Guarantor may sell or otherwise
dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor
is the surviving Person) another Person, other than the Company or another Guarantor, unless:

 

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

 

(b)          either:

 

(i)          subject
to Section 11.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving
any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture and its Note
Guarantee on the terms set forth herein or therein pursuant to a supplemental indenture in form and substance satisfactory to the
Trustee; or

 

(ii)         the
Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including
without limitation, Section 4.10 hereof.

 

In case of any
such consolidation, merger, sale or conveyance and upon the assumption by the successor Person as provided in clause (b)(i) above,
by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to
the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions
of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor
with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any
or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed
by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and
benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture
as though all of such Note Guarantees had been issued at the date of the execution hereof.

 

Except as set forth in Articles IV and V
hereof, and notwithstanding clauses (b)(i) and (ii) above, nothing contained in this Indenture or in any of the Notes will prevent
any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance
of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

  

    	94

    	 

    

 

11.05.   Releases.
The Note Guarantee of a Guarantor will be released:

 

(a)          In
the event of any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger
or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted
Subsidiary of the Company otherwise permitted by this Indenture;

 

(b)          In
the event of any sale or other disposition of all of the Capital Stock of that Guarantor owned by the Company and its subsidiaries
to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the
Company otherwise permitted by this Indenture;

 

(c)          If
the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the provisions
of this Indenture; or

 

(d)          Upon
Legal Defeasance or satisfaction and discharge of this Indenture in accordance with Articles VIII and XII hereof, respectively.

 

Upon delivery by the Company to the Trustee
of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect, the Trustee shall execute any documents reasonably
requested by the Company in writing in order to evidence the release of the Guarantor from its obligations under its Note Guarantee.

 

Any Guarantor not released from its obligations
under its Note Guarantee as provided in this Section 11.05 will remain liable for the full amount of principal of and interest
and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article
XI.

 

Article
XII

Satisfaction and Discharge

 

12.01.   Satisfaction
and Discharge. This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

 

(a)          either:

 

(i)          all
Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose
payment money has heretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for
cancellation; or

 

(ii)         all
Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice
of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited
or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars,
non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts
as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the
Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest and any Additional Amounts
that may be due and payable, if any, to the date of maturity or redemption;

  

    	95

    	 

    

 

(b)          no
Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of,
or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or
any Guarantor is bound;

 

(c)          the
Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

 

(d)          the
Company has delivered irrevocable written instructions to the Trustee under this Indenture to apply the deposited money toward
the payment of the Notes at maturity or on the Redemption Date, as the case may be.

 

In addition,
the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee
stating that all conditions precedent to satisfaction and discharge have been satisfied.

 

Notwithstanding
the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee
pursuant to subclause (ii) of clause (a) of this Section 12.01, the provisions of Sections 8.06 and 12.02 hereof will survive.
In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their
terms, survive the satisfaction and discharge of this Indenture.

 

12.02.   Application
of Trust Money. Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section
12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for
whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to
the extent required by law.

 

If the Trustee or Paying Agent is unable
to apply any money or Government Securities in accordance with Section 12.01 hereof by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application,
the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as
though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Company has made any payment of principal
of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee
or Paying Agent.

13.01.   Currency
Indemnity. U.S. dollars are the sole currency of account and payment for all sums payable by the Company or the Guarantors
under or in connection with the Notes, including damages. To the greatest extent permitted under applicable law, any amount received
or recovered in a currency other than dollars (whether as a result of, or of the enforcement of, a judgment or order of a court
of any jurisdiction, in the winding up or dissolution of the Company or the Guarantors or otherwise) by any Holder of a Note in
respect of any sum expressed to be due to it from the Company or the Guarantors shall constitute a discharge to the Company or
the Guarantors only to the extent of the dollar amount which the recipient is able to purchase with the amount so received or recovered
in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date,
on the first date on which it is practicable to do so). If that dollar amount is less than the dollar amount expressed to be due
to the recipient under any Note, the Company or the Guarantors shall indemnify the recipient against any loss sustained by it as
a result. In any event, the Company or the Guarantors shall indemnify the recipient against the cost of making any such purchase.
For the purposes of this Section 13.01, it will be sufficient for the Holder of a Note to certify in a satisfactory manner (indicating
the sources of information used) that it would have suffered a loss had an actual purchase of dollars been made with the amount
so received or recovered in that other currency on the date of receipt or recovery (or, if a purchase of dollars on such date had
not been practicable, on the first date on which it would have been practicable, it being required that the need for a change of
date be certified in the manner mentioned above). These indemnities constitute a separate and independent obligation from the other
obligations of the Company or the Guarantors, shall give rise to a separate and independent cause of action, shall apply irrespective
of any indulgence granted by any Holder of a Note and shall constitute in full force and effect despite
any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under any Note.

 

13.02.   Trust
Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA §318(c),
the duties imposed by the TIA will control.

Capitalized terms
used herein have the meanings assigned to them in the Indenture referred to below unless otherwise
indicated.

 

(1)         INTEREST.
Maxcom Telecomunicaciones, S.A.B. de C.V., a sociedad anónima bursátil de capital variable organized under
the laws of Mexico (the “Company” or the “Issuer”), promises to pay interest
on the principal amount of this Note at 6% per annum from (and including) the Issue Date to (and excluding) June 14, 2016,
7% per annum from (and including) June 15, 2016 to (and excluding) June 14, 2018, and
8% per annum from (and including) June 15, 2018 to (and excluding) June 15, 2020. The Company shall pay interest semi-annually
in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day
(each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing
Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further
that the first Interest Payment Date shall be December 15, 2013. The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal, interest and premium, if any, from time to time on demand at
a rate that is 2% per annum in excess of the then applicable interest rate to the extent lawful. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

OF PAYMENT. The Company shall pay or cause to be paid interest on the Notes (except defaulted interest) to the Persons
who are registered Holders of Notes at the close of business on the June 1 or December 1 (each, a “Record Date”)
preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest
Payment Date, except as provided in Section 2.13 of the Indenture with respect to defaulted interest. The Notes will be payable
as to principal, interest, Additional Amounts, if any, and premium, if any, at the office or agency of the Paying Agent and Registrar,
or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in
the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect
to principal of and interest, premium on, all Global Notes and all other Notes the Holders of which will have provided wire transfer

REDEMPTION. (a) At any time prior to June 15, 2017, the Company may on any one or more occasions redeem up to 35% of the aggregate
principal amount of Notes issued under the Indenture at a redemption price of 106% of the principal amount thereof, plus accrued

or after June 15, 2017, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ written
notice, at the redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest and Additional Amounts, if any, on the Notes redeemed, to the applicable Redemption Date, if redeemed
during the periods indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest on
the relevant interest payment date:

 

	Year	 	Percentage	 
	From June 15, 2017 through June 14, 2018	 	 	103.00	%
	From June 15, 2018 through June 14, 2019	 	 	101.50	%
	From June 15, 2019 and thereafter	 	 	100.00	%

 

(d)          The
Company may at its option at any time, upon giving not less than 30 nor more than 60 days’ written
notice to Holders, redeem all (but not less than all) of the Notes then outstanding, at 100% of the aggregate principal amount
thereof, plus accrued and unpaid interest and Additional Amounts, if any, to such Redemption Date (subject to the right of Holders
of record on the relevant record date to receive interest due on the relevant interest payment date), in the event the Company
has become, or would become, obligated to pay, on the next interest payment date on which any amount would be payable with respect
to such Notes, any Additional Amounts in excess of the Additional Amounts the Company would be obligated to pay if payments made
on the Notes were subject to withholding or deduction of Mexican taxes at a rate in excess of 4.9 percent (“Excess Additional
Amounts”) as a result of: (a) any change in, or amendment to, the laws (including any regulations promulgated thereunder)
of the relevant Tax Jurisdiction; or (b) any change in the official application, administration or interpretation of such laws
or regulations in the relevant Tax Jurisdiction (each of (a) and (b) a “Change of Tax Law”), if (1) the above-mentioned
change or amendment is announced on or after the Issue Date (or, if later, the date on which a jurisdiction becomes a relevant
Tax Jurisdiction), (2) there has been a further issuance, such obligation to pay Excess Additional Amounts would have arisen absent
a further issuance of the Notes pursuant to the Indenture, and (3) such obligation to pay Excess Additional Amounts cannot be avoided
by the Company taking reasonable measures available to it (including, without limitation, changing the jurisdiction from or through
which payments are made).

  

    	A-5

    	 

    

 

(6)         MANDATORY
REDEMPTION. The Company is not required to make mandatory redemption or sinking fund payments
with respect to the Notes. The Company may at any time and from time to time purchase Notes in the open market or otherwise.

 

(7)         REPURCHASE
AT THE OPTION OF HOLDER. (a) If there is a Change of Control, the Company shall be required to make an offer (a “Change
of Control Offer”) to each Holder to repurchase all or any part (equal to U.S.$150,000
or integral multiples of U.S.$1.00 above U.S.$150,000) of each Holder’s Notes at a purchase price in cash equal to 101% of
the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Amounts, if any, on
the Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest
due on the relevant Interest Payment Date (the “Change of Control Payment”).  Within 10 days following
the date on which a Change of Control occurs, the Company shall mail, by first-class mail or, if sent through DTC, send in accordance
with DTC’s applicable procedures, a notice to each Holder, with a copy to the Trustee, setting forth the procedures governing
the Change of Control Offer as required by the Indenture.

 

(b)          If
the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within five days
of each date on which the aggregate amount of Excess Proceeds exceeds U.S.$5,000,000, within five days thereof, the Company shall
make an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales
of assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase the maximum principal
amount of Notes (including any Additional Notes) and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest
thereon to the date of purchase, in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company (or such Restricted Subsidiary) may use such Excess Proceeds for any purpose not
otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered
into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu
Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will
be reset at zero. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company
prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of
Holder to Elect Purchase” attached to the Notes.

  

    	A-6

    	 

    

 

(c)         The
Company shall be required to use 50% of any Excess Capital Contribution greater than U.S.$5,000,000 (the “Excess Capital
Contribution Amount”) to make an offer to each Holder of Notes to repurchase such Holder’s Notes at the offer price
specified in the next sentence (an “Excess Capital Contribution Offer”). The offer price in any Excess Capital
Contribution Offer will be equal to 85% of the principal amount of the Notes plus accrued and unpaid interest and Additional Amounts,
if any, on the Notes repurchased to the date of purchase, and shall be payable by the Company in cash. If the aggregate principal
amount of Notes tendered into such Excess Capital Contribution Offer, taking into account the offer price of 85% of the principal
amount of the Notes, exceeds the Excess Capital Contribution Amount, the Trustee shall select the Notes to be purchased in accordance
with the selection procedures set forth in Section 3.02 of the Indenture. Any portion of the Excess Capital Contribution that remains
after consummation of an Excess Capital Contribution Offer may be used by the Company for any purpose not otherwise prohibited
by the Indenture. Within 10 days following the date on which the Company has received all Excess Capital Contributions to be made
in connection with the Purchaser’s Capital Contribution (and the total Excess Capital Contributions exceed U.S.$5,000,000),
the Company shall mail, by first-class mail or, if sent through DTC, send in accordance with DTC’s applicable procedures,
a notice to each Holder, with a copy to the Trustee, stating the Excess Capital Contribution Amount and offering to repurchase
Notes on the Excess Capital Contribution payment date specified in such notice, which date will be no earlier than 30 days and
no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the Indenture and described in
such notice.

 

(8)         NOTICE
OF REDEMPTION. Subject to the provisions of Section 3.09 of the Indenture, notice of redemption will be mailed at least 30
days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be
redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if
the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes and portions
of Notes to be selected for redemption or purchase will be in minimum amounts of U.S.$150,000 or whole multiples of U.S.$1.00 in
excess thereof ; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of
such Notes, even if not a multiple of U.S.$1.00, will be redeemed or purchased.

 

(9)         DENOMINATIONS,
TRANSFER, EXCHANGE. The Notes are in registered form without coupons, initially issuable in minimum denominations of U.S.$150,000
and integral multiples of U.S.$1.00 in excess of thereof. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents in connection with a transfer of Notes. Holders will be required to pay all taxes
due on transfer or other similar governmental charges required to be paid in connection therewith. The Company shall not be required
to transfer or exchange any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being
redeemed in part. Also, the Company shall not be required to transfer or exchange any Notes for a period of 15 days before a selection
of Notes to be redeemed.

  

    	A-7

    	 

    

 

(10)        PERSONS
DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

 

(11)        AMENDMENT,
SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes or the Note Guarantees may be amended or supplemented
with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes including Additional
Notes, if any, voting as a single class, and any existing Default or Event or Default or compliance with any provision of the Indenture
or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of
the then outstanding Notes, including Additional Notes, if any, voting as a single class (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes). Without the consent of any Holder
of a Note, the Indenture or the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency,
to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s
or a Guarantor’s obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation or sale of
all or substantially all of the Company’s or such Guarantor’s assets in compliance with the Indenture, as applicable,
to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely
affect the legal rights under the Indenture of any such Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA, to allow any Guarantor to execute a supplemental indenture and/or a
Note Guarantee with respect to the Notes, to conform the text of the Indenture to any provisions of the “Description of Step-Up
Senior Notes” exhibit of the Disclosure Statement, to the extent that such provision in that “Description of Step-Up
Senior Notes” was intended to be a verbatim recitation of a provision of the Indenture or the Notes, as evidenced by an Officers’
Certificate, to provide for the issuance of Additional Notes under the Indenture to the extent otherwise so permitted under the
terms of the Indenture, or to evidence and provide for the acceptance of appointment by a successor Trustee.

  

    	A-8

    	 

    

 

(12)        DEFAULTS
AND REMEDIES. Events of Default include: (a) default for 30 days in the payment when due of interest or any Additional Amounts
on the Notes; (b) default in the payment when due (whether at maturity, upon redemption or otherwise) of the principal of, or premium,
if any, on, the Notes; (c) failure by the Company or any of its Restricted Subsidiaries to comply with Sections 4.15, 4.24 or 5.01
of the Indenture; (d) failure by the Company or any of its Restricted Subsidiaries for 60 days after notice to the Company by the
Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to
comply with any of the other covenants or agreements in the Indenture; (e) default under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company
or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries),
whether such Indebtedness or Guarantee now exists, or is created after the date of the Indenture, if that default (i) is caused
by a failure to pay principal of, or interest or premium, if any on, such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such default or (ii) results in the acceleration of
such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been
so accelerated aggregates U.S.$10,000,000 or more; (f) failure by the Company or any of its Restricted Subsidiaries to pay final
judgments entered by a court or courts of competent jurisdiction aggregating in excess of U.S.$10,000,000, which judgments are
not paid, discharged or stayed for a period of 60 days; (g) except as permitted by the Indenture, any Note Guarantee is held in
any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor,
or any authorized Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee, or any
Collateral Document is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force
and effect; and (h) certain events of bankruptcy, reorganization, concurso mercantil, quiebra, insolvency or similar
laws of Mexico, the United States or any other jurisdiction described in the Indenture with respect to the Company or any of its
Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute
a Significant Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate
principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will
become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except
as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding
Notes may direct the Trustee in writing in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes
notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal
or interest or premium, if any, or a Default pursuant to clauses (e) or (f) of Section 6.01 of the Indenture) if it determines
that withholding notice is in their interest. The Trustee may, in good faith as determined by a Responsible Officer of the
Trustee, refuse to follow any direction that conflicts with applicable law or the Indenture that the Trustee determines may be
unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. The
Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf
of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences
under the Indenture except a continuing Default or Event of Default in the payment of the principal, interest or premium, if any,
on the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and
the Company is required, upon becoming aware of any Default or Event of Default under the Indenture governing the Notes, to deliver
to the Trustee a statement specifying such Default or Event of Default.

 

(13)        TRUSTEE
DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans
to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its
Affiliates, as if it were not the Trustee. However, if the Trustee acquires any conflicting interest,
it must eliminate such conflict within 90 days and, if required, apply to the SEC for permission to continue as Trustee (if the
Indenture has been qualified under the TIA) or resign.

 

(14)        NO
RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator or stockholder of the Company
or any of Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the
Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
the issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

 

SUPPLEMENTAL INDENTURE (this “Supplemental
Indenture”), dated as of ____________, 20__, among ______________(the “Guaranteeing Subsidiary”),
a subsidiary of __________________________ (or its permitted successor), a [•] corporation (the “Company”),
the Company, the other Guarantors (as defined in the Indenture referred to herein) and ______________, as trustee under the
Indenture referred to below (the “Trustee”).

 

WITNESSETH

 

WHEREAS, the
Company has heretofore executed and delivered to the Trustee an indenture, dated as of October 11, 2013 (the “Indenture”)
providing for the issuance of Step-Up Senior Notes due 2020 (the “Notes”);

 

WHEREAS, the
Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute
and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee
all of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note
Guarantee”); and

 

WHEREAS, pursuant
to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental
Indenture.

 

NOW, THEREFORE, in consideration of the
foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary
and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

 

1.          CAPITALIZED
TERMS. Capitalized terms used herein without definition shall have the meanings assigned
to them in the Indenture.

 

2.          AGREEMENT
TO GUARANTEE. The Guaranteeing Subsidiary hereby provides
an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including

by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of
the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC
that such a waiver is against public policy.

construction hereof.

 

8.          THE

whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals
contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Company.

    	D-1

    	 

    

 

REPRESENTATIONS

 

SOLE. Each Obligor represents that, given that
the Obligors form part of the same corporate group and by virtue of the Obligors’ operations in accordance with their respective
corporate purposes, (a) it has certain ongoing commercial relationships with the other Obligors and accounting practices that are
consistent with those of the other Obligors, (b) such transactions can be effectuated in the form of a single transaction on a
given cutoff date, and (c) it has determined that it is appropriate to execute this Agreement pursuant to the following terms:

 

CLAUSES

 

FIRST. Each of the Obligors, as a lender, grants
to each of the other Obligors, as a borrower, a current unlimited account line of credit in accordance with the provisions of article
296 of the Mexican General Law of Negotiable Instruments and Credit Transactions (Ley General de Títulos y Operaciones
de Crédito, or the “Law”) (each a “Credit”), which shall be used in connection
with activities within their respective corporate purposes (subject to any contractual limitations agreed with third parties, including,
but not limited to, the limitations existing under the Restructuring Documents).

 

Such line of credit is a revolving credit line granted in accordance
with the provisions of article 296 of the Law. The Obligors are permitted to make and collect payments in respect of such Ordinary
Course Intercompany Indebtedness so long as such Ordinary Course Intercompany Indebtedness is incurred, and such payments are made
or collected, in the ordinary course of business consistent with past practice.

 

SECOND. Borrowings by the Obligors under this
Agreement may be made for any purpose, including in connection with the provision of services transactions or any transfer of obligations
or rights (subject to any contractual limitations agreed with third parties, including, but not limited to, the limitations existing
under the Restructuring Documents); it being understood that the Obligors shall be permitted to incur any
Intercompany Indebtedness that complies with the terms and conditions of the Indenture and this Agreement.

 

THIRD. The Obligors shall collect or pay interest
rates similar to those prevailing in the market; it being understood that such rates may be subject to the
market fluctuations.

 

FOURTH. Any borrowings under this Agreement may
be effected in national or foreign currencies and must be consistent with the terms and conditions of the Indenture in all respects.

 

FIFTH. Within the thirty calendar days immediately
following the closing of each quarterly period ending on March 31, June 30, September 30 and December 31 of each calendar year,
commencing the next day immediately after the closing of the next quarterly period subsequent to the execution date of this Agreement,
the Company shall deliver:

 

(i)          to
the Subordinated Subsidiaries, an account statement including the transactions corresponding to the immediately preceding quarter
pursuant to this Agreement; and

 

(ii)         to
the Indenture Trustee (as defined below) and the Collateral Agent, a listing of all transactions and outstanding balances during
the preceding quarter pursuant to this Agreement.

 

    	D-2

    	 

    

 

Notwithstanding the foregoing, the Obligors acknowledge that
payment of the balances owing by each such Obligor shall be payable pursuant to the terms and conditions agreed by each Obligor

this Agreement is terminated for any reason.

 

SIXTH. The commissions and expenses derived from
the transactions referred to in this Agreement, shall be included in the aforementioned account statements.

 

SEVENTH. The registration of a Credit in the relevant
account pursuant to this Agreement shall not be construed as an admission or a waiver by any party regarding the validity of the
actions or agreements from which such Credit arises. In the event that any such action or agreement becomes null and void, the
corresponding registration pursuant to this Agreement shall be cancelled.

 

EIGHTH. Remittances of negotiable instruments
shall be deemed to be subject to the condition precedent of “Subject to Collection”, and therefore, in the event
that an Obligor under a negotiable instrument is unable to make payment thereunder, such Obligor shall timely notify the other
party thereto in order for it to effect the corresponding cancellation registries (including the restitution of the instrument
or instruments, if applicable).

 

NINTH. This Agreement is for an indefinite term
and, upon payment in full of the Step-Up Senior Notes, any of the Obligors may terminate this Agreement by providing prior written
notice to the other Obligors at least thirty calendar days prior to the proposed termination date.

 

TENTH. Any actions with respect to any errors
or omissions in relation to this Agreement or the borrowings thereunder must be brought within six months of the cancellation date
of the corresponding borrowing.

 

ELEVENTH. The parties hereto hereby agree as follows:

 

(i)          all
indebtedness incurred pursuant to this Agreement (collectively, the “Second Place Obligations”) shall at all
times, and for all legal purposes, be subordinated to the prior payment in full of the Step-Up Senior Notes and the obligations
under the Indenture;

 

(ii)         in
order to fulfill the subordination obligation referred to in section (i) above, each of the Obligors hereby authorizes the entry
into the Irrevocable Administration and Source of Payment Trust with Reversion Rights Agreement No. [●], dated as of [●],

(iii)        in
the event of a Concurso Proceeding (Procedimiento Concursal) (as defined in the Trust), the Obligors, in their capacity
as lenders, hereby agree that any payment in favor thereof made as Income (Ingresos) (as defined in the Trust), shall be
subject to the terms and conditions of the Trust and shall be applied first to the payment of the Step-Up Senior Notes and the
obligations under the Indenture determined as common Recognized Lenders (Acreedores Reconocidos) (as defined in the Trust)
pursuant to article 222 of the LCM in such Concurso Proceeding, and shall be applied to the payment of the Second Place Obligations
only after the Step-Up Senior Notes and the obligations under the Indenture have been paid in full.

 

    	D-3

    	 

    

 

TWELFTH. All contracts entered
into by the Obligors in relation to the Intercompany Indebtedness to which none of the Consenting Senior Noteholders, the Indenture
Trustee and/or the Collateral Agent is a party shall be solely among the Obligors, and the Consenting Senior Noteholders, the Indenture
Trustee and/or the Collateral Agent shall incur no liability in respect thereof; provided, however, that the Consenting
Senior Noteholders the Indenture Trustee and the Collateral Agent shall be third party beneficiaries of such contracts to the extent
provided herein and shall have the right to enforce such contracts to such extent.

 

THIRTEENTH. In the event that an additional subsidiary
of the Company becomes a party to the Trust pursuant to the Intercompany Credit Account Agreement (Contrato de Cuenta Corriente
Intercompañías) (as amended, restated, supplemented or otherwise modified from time to time), upon execution
and delivery by such subsidiary of a counterpart of this Agreement, such subsidiary shall become a party hereunder with the same
force and effect as if originally named herein.

 

FOURTEENTH. The Obligors acknowledge that the
execution of this Agreement does not constitute a novation, remission or substitution of the debts contracted between them prior
to the date hereof.

 

FIFTEENTH. This Agreement shall be governed by
and construed in accordance with the laws of Mexico, including the Law. For all matters regarding the interpretation and performance
of this Agreement, the parties hereto expressly and irrevocably submit themselves to the jurisdiction of the competent courts of
the Federal District of Mexico, expressly waiving their right to any other jurisdiction to which they may be entitled by virtue
of their present or future domiciles or otherwise.

 

SIXTEENTH. This Agreement is made and entered
into solely for the benefit of the parties hereto, the Indenture Trustee, the Collateral Agent and the Holders (as such term is
defined in the Step-Up Senior Notes), and no other person or entity shall have any right of action hereon, right to claim any right
or benefit from the terms contained herein, or be deemed a third party beneficiary hereunder.

 

SEVENTEETH. The failure of any party to exercise
and/or delay in exercising any power or right hereunder shall not operate as a waiver thereof, nor shall any single or partial
exercise of any such power or right preclude any other or further exercise of any other power or right hereunder. Further, the
waiver by any party of any right or remedy hereunder on any occasion shall not be construed as a waiver of any such right or remedy
on any future occasion.

 

EIGHTEENTH. The parties further agree that this
Agreement shall not be amended or modified except by a writing signed by each of the parties hereto, the Indenture Trustee, the
Collateral Agent and the Consenting Senior Noteholders.

 

NINETEENTH. Notwithstanding anything herein to
the contrary, this Agreement shall be subject to the terms and conditions contained in Articles VII and X of the Indenture, on
a mutatis mutandis basis. Any notices hereunder required to be delivered to the Indenture Trustee or the Collateral Agent shall
be governed by Section 13.03 of the Indenture.

 

In consideration of the foregoing, the parties hereto have caused
this Agreement to be duly executed and delivered in the city of Mexico, on [●], 2013.
