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

(h)    General Provisions Relating to Transfers and Exchanges. 

(1)    To permit registrations of transfers and exchanges, the Company will execute and the Trustee will
authenticate Global Notes and Definitive Notes upon receipt 

  
 59 













 
of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

(2)    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 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 2.10, 3.06, 3.07, 4.10, and 9.04 hereof). 

(3)    The Registrar will not be required to register the transfer of or exchange of any Note selected for
redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 

(4)    All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global
Notes or Definitive Notes will be the valid obligations of the 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. 
 (5)    Neither the Registrar nor the Company will be required: 

(A)    to issue, to register the transfer of or to exchange any Notes during a period beginning at the
opening of business 15 days before the 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. 

(6)    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, premium, if any, and interest on, the Notes and for all other purposes, and none
of the Trustee, any Agent or the Company shall be affected by notice to the contrary. 
 (7)    The
Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 

(8)    All certifications, certificates and Opinions of Counsel required to be submitted to the Company and
the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

 Notwithstanding anything to the contrary herein, neither the Trustee nor the Registrar shall
be responsible for ascertaining whether any transfer complies with the registration provisions of or exemptions from the Securities Act or applicable state securities laws. 

Section 2.07    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 will issue and the Trustee, upon receipt of an Authentication Order, will 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
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. 

Section 2.08    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 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant
to Section 2.07 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. 
 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 the Notes will be deemed to be no longer outstanding and will cease to accrue interest. 

Section 2.09    Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the 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 will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 

  
 61 













 Section 2.10    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 will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 

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

Section 2.11    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, replacement or cancellation and will destroy canceled Notes
(subject to the record retention requirements of the Exchange Act and the customary procedures of the Trustee). 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. 
 Section 2.12    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 will notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such
special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the 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 to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

Section 2.13    Further Issuances. 

The Company may, from time to time, without notice to or the consent of the Holders of the Notes, increase the principal amount of the Notes
under this Indenture and issue such increased principal amount (or any portion thereof), in which case any Additional Notes so issued shall have the same form and terms (other than the date of issuance and, under certain circumstances, the date from
which interest thereon shall begin to accrue), and shall carry the same right to receive accrued and unpaid interest, as the Notes previously issued, and such Additional Notes shall form a single series with the Notes; provided that the
aggregate principal amount of Notes issued under this Indenture (when taken together with the outstanding principal amount of all other Pari Passu Lien Debt) as of the date of issuance of any such Additional Notes, may not exceed the lesser of (x)
$3,750,000,000 and (y) the amount that would cause the Collateral Coverage Ratio with respect to 

  
 62 













 
such date of issuance to equal 2.0 to 1.0. Any Additional Notes that are not fungible with the Notes for U.S. Federal income tax purposes must be issued under a separate CUSIP number. 

Section 2.14    No Reissuance of Notes. 

The Company may not reissue a Note that has matured, been redeemed, been purchased by the Company at the Holder’s option upon a Change of
Control or otherwise been canceled, except for registration of transfer, exchange or replacement of such Note.

otherwise included in the Consolidated Net Income of the Parent for such period; 
 provided, however, there shall be no
increase in respect of any amount contemplated by clause (iv), (v) or (vi) of this Section 4.07(a) pursuant to any such clause to the extent such amount otherwise increases the capacity of the Parent or any of its Restricted Subsidiaries

pre-delivery financing and related interest expense (whether or not capitalized) and premium (if any), delivery and late charges and other costs associated with such acquisition (as so calculated, for purposes
of this proviso, the “financing costs”)) but, if such principal amount exceeds such financing costs, it may not exceed the aggregate Fair Market Value of the item or items securing such Indebtedness (which Fair Market Value may, at
the time of an advance commitment, be determined to be the Fair Market Value at the time of such commitment or (at the option of the issuer of such Indebtedness) the Fair Market Value projected for the time of incurrence of such Indebtedness); 

(14)    Indebtedness issued to current or former directors, consultants, managers, officers and employees
and their spouses or estates (a) to purchase or redeem Capital Stock of the Parent issued to such director, consultant, manager, officer or employee in an aggregate principal amount not to exceed $30.0 million in any twelve-month period or
(b) pursuant to any deferred compensation plan approved by the Board of Directors of the Parent; 

(15)    reimbursement obligations in respect of standby or documentary letters of credit or banker’s
acceptances; 
 (16)    surety and appeal bonds that do not secure judgments that constitute an Event of
Default; 
 (17)    Indebtedness of the Parent or any of its Restricted Subsidiaries to Credit Card,
travel charge or clearing house processors in connection with Credit Card processing, travel charge or clearing house services incurred in the Ordinary Course of Business, whether in the form of hold-backs or otherwise; 

(18)    the incurrence by a Receivables Subsidiary of Indebtedness in a Qualified Receivables Transaction
that is without recourse to the Parent or to any other Restricted Subsidiary of the Parent or their assets (other than such Receivables Subsidiary and its assets and, as to the Parent or any other Restricted Subsidiary of the Parent, other than
Standard Securitization Undertakings) and is not guaranteed by any such Person; 
 (19)    the incurrence
of Indebtedness of the Parent or any of its Restricted Subsidiaries owed to one or more Persons in connection with the financing of insurance premiums in the Ordinary Course of Business; 

(20)    Indebtedness in respect of or in connection with tax-exempt
or tax-advantaged municipal bond and similar financings related to Aircraft Related Facilities; 

(21)    Credit Card purchases of fuel; 

  
 75 













 (22)    Indebtedness arising from agreements of the
Parent or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, assets or a
Subsidiary; provided that, in the case of a disposition, the maximum assumable liability in respect of all such Indebtedness shall at no time exceed the gross proceeds, including non-cash proceeds (the
Fair Market Value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value) actually received by the Parent or any of its Restricted
Subsidiaries in connection with such disposition; 
 (23)    Indebtedness of the Parent or any of its
Restricted Subsidiaries consisting of take-or-pay or like obligations contained in supply, maintenance, repair, power-by-the-hour, overhaul or like agreements either (A) entered into in the Ordinary Course of Business or (B) otherwise customary, typical or appropriate
for a Permitted Business; 
 (24)    the incurrence by the Parent or any of its Restricted Subsidiaries
of additional Indebtedness that is either (A) unsecured and expressly contractually subordinated in right of payment to the prior payment in full in cash of all Notes and the Parent’s Obligations on terms not materially less favorable to
the Holders of the Notes than those customary at the time of incurrence (determined in good faith by a senior financial officer of the Parent) for senior subordinated “high yield” debt securities or (B) unsecured, pari passu with all
Notes and the Parent’s Obligations and convertible into common stock of the Parent; provided that the aggregate principal amount of Indebtedness incurred pursuant to clauses (A) and (B) together, including all Permitted Refinancing
Indebtedness incurred to renew, refund, refinance, replace, extend, defease or discharge any Indebtedness incurred pursuant to this clause (24), does not exceed $1.5 billion at any time outstanding; and 

(25)    the incurrence by the Parent or any of its Restricted Subsidiaries of additional Indebtedness in an
aggregate principal amount (or accreted value, as applicable), including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, extend, defease or discharge any Indebtedness incurred pursuant to this clause (25), not
to exceed $3.0 billion, at any time outstanding. 
 (c)    For purposes of determining compliance with this
Section 4.08, if an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt set forth in clauses (1) through (25) of Section 4.08(b) hereof or is entitled to be incurred pursuant to
Section 4.08(a) hereof, the Parent shall be permitted to classify all or a portion of 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 4.08; provided that the term “Existing Indebtedness” shall not include any Indebtedness that is permitted to be incurred under clause (1) or (3) of the definition of Permitted Debt. Additionally, all or any
portion of any item of Indebtedness may later be reclassified as having been incurred pursuant to Section 4.08(a) hereof or under any category of Permitted Debt described in clauses (1) through (25) of Section 4.08(b) so long as such
item (or portion) of Indebtedness is permitted to be incurred pursuant to such provision at the time of reclassification. 

  
 76 













 (d)    None of the following shall constitute an incurrence of
Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.08: 

(1)    the accrual of interest or preferred stock dividends; 

(2)    the accretion or amortization of original issue discount; 

(3)    the payment of interest on any Indebtedness in the form of additional Indebtedness with the same
terms; 
 (4)    the reclassification of preferred stock or any other instrument or transaction as
Indebtedness due to a change in accounting principles or in GAAP; and 
 (5)    the payment of dividends
on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock. 

(e)    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 utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred.
Notwithstanding any other provision of this Section 4.08, the maximum amount of Indebtedness that the Parent or any of its Restricted Subsidiaries may incur pursuant to this Section 4.08 shall not be deemed to be exceeded solely as a
result of fluctuations in exchange rates or currency values. 
 (f)    The amount of any Indebtedness outstanding as of
any date shall be: 
 (1)    the accreted value of the Indebtedness as of such date, in the case of any
Indebtedness issued with original issue discount; 
 (2)    the principal amount of the Indebtedness as
of such date, in the case of any other Indebtedness; and 
 (3)    in respect of Indebtedness of another
Person secured by a Lien on the assets of the specified Person, the lesser of: 
 (A)    the Fair Market
Value of such assets as of such date; and 
 (B)    the amount of the Indebtedness of the other Person as
of such date. 
 Section 4.09    Reserved. 

Section 4.10    Offer to Repurchase Upon Change of Control. 

(a)    If a Change of Control occurs, each Holder of the Notes shall have the right to require the Company to repurchase
all or any part (equal to a minimum denomination of $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer (a “Change of Control Offer”) at a purchase price in cash equal to 101%
of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest on the Notes repurchased to (but 

  
 77 













 
not including) the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall deliver (with a copy to the Trustee) a
notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 

(1)    that the Change of Control Offer is being made pursuant to this Section 4.10 and that all Notes
tendered shall be accepted for payment; 
 (2)    the purchase price and the purchase date, which shall
be no earlier than 30 days and no later than 60 days from the date such notice is delivered (the “Change of Control Payment Date”); 

(3)    that any Note not tendered shall continue to accrue interest; 

(4)    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 shall cease to accrue interest after the Change of Control Payment Date; 

(5)    that Holders of Notes electing to have any Notes purchased pursuant to a Change of Control Offer
shall be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer the Notes 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; 

(6)    that Holders of Notes shall 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 its election to have the Notes purchased; and 

(7)    that Holders of Notes whose Notes are being purchased only in part shall be issued new Notes equal
in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 

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 of Control. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue of such
compliance. 
 (b)    On the Change of Control Payment Date, the Company shall, to the extent lawful: 

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

  
 78 













 (2)    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 

(3)    deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The
Paying Agent shall promptly deliver (or pay by wire transfer) (but in any case not later than five days after the Change of Control Payment Date) to each Holder of the Notes properly tendered the Change of Control Payment for such Notes, and the
Company shall issue, and the Trustee shall promptly authenticate and deliver (or cause to be transferred by book entry) to each such 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 Indenture or the Notes: 

(1)    the Company shall not be required to make a Change of Control Offer upon a Change of Control if
(i) 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 4.10 and purchases all Notes properly tendered and not withdrawn under the Change
of Control Offer or (ii) notice of redemption with respect to all Notes has been given pursuant to Sections 3.01, 3.03 and 3.07 hereof, unless and until there is a default in payment of the applicable redemption price; and 

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

(d)    If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not
withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the
Company or such third party will have the right, upon not less than 10 days nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes
that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but not including) the redemption date. Any redemption pursuant to this
Section 4.10(d) shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. 
 (e)    For the
avoidance of doubt, the Company’s failure to make a Change of Control Offer would constitute a Default under clause (3) of the definition of “Event of Default” in Section 6.01 hereof and not clause (1) or (2) of the
definition of “Event of Default” in Section 6.01 hereof, but the failure of the Company to pay the Change of Control Payment when due shall constitute a Default under clause (1) of the definition of “Event of Default”
in Section 6.01 hereof. 
 Section 4.11    Designation of Restricted and Unrestricted Subsidiaries.


  
 79 













 (a)    The Board of Directors of the Parent may designate any Restricted
Subsidiary (other than the Company) 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 Parent and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of the designation. That designation shall be permitted only if the
Investment would be permitted at that time under Section 4.07 hereof and if the Restricted Subsidiary otherwise meets the definition of an “Unrestricted Subsidiary.” 

(b)    Any designation of a Subsidiary of the Parent as an Unrestricted Subsidiary shall be evidenced to the Trustee by
filing with the Trustee a certified copy of a resolution of the Board of Directors of the Parent giving effect to such designation and an Officer’s Certificate certifying that such designation complied with the preceding conditions. The Board
of Directors of the Parent may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation shall be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of
the Parent of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation shall be permitted only if (i) the incurrence of such Indebtedness is permitted under Section 4.08 hereof, calculated on a pro forma basis as
if such designation had occurred at the beginning of the applicable reference period and (ii) no Default would be in existence following such designation. 

(c)    For the avoidance of doubt, the Company may not be designated as an Unrestricted Subsidiary. 

Section 4.12    Limitations on Liens  

(a)    The Parent will not, and will 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 property or asset that constitutes Collateral, except Permitted Liens. 

Section 4.13    Delivery of Appraisals 

(a)    Within: 

(1)    the thirty (30) day period prior to May 31 and November 30 of each year commencing
November 30, 2020; and; 
 (2)    the 45 day period following a request by the Trustee or the
Collateral Trustee if an Event of Default has occurred and is continuing, 
 the Company will deliver to the Trustee and the Collateral Trustee one or more
Appraisals establishing the Appraised Value of the First Lien Collateral (other than with respect to cash or Cash Equivalents). The Company will make copies of these Appraisals available on a private, restricted website to which noteholders,
prospective investors, broker-dealers and securities analysts are given access. For avoidance of doubt, the Company may (but shall not be required to) deliver Appraisals to the Trustee and the Collateral Trustee on additional dates with greater
frequency than is required pursuant to the provisions above. 

  
 80 













 (b)    The Company will deliver to the Trustee and the Collateral
Trustee any Appraisal with respect to the Second Lien Collateral that is delivered to the administrative agent under the 2014 Credit Agreement or any other Priority Lien Debt, within five business days of such delivery to such administrative agent,
and the Company will make copies of these Appraisals available on a private, restricted website to which noteholders, prospective investors, broker-dealers and securities analysts are given access. 

(c)    For the avoidance of doubt, the Company’s failure to deliver any Appraisal required by clauses (1) or (2)
above will be deemed to constitute an Event of Default for purposes of clause (3) under Section 6.01 hereof. 

(d)    Within 10 business days after any Appraisal is required to be delivered pursuant to Section 4.13, the Company
will furnish to the Trustee a summary of each such Appraisal containing only information summarizing the results of such Appraisal (all of which will be made publicly available) and will post the complete Appraisal on a private, restricted website
to which noteholders, prospective investors, broker-dealers and securities analysts are given access. 

Section 4.14    Collateral Coverage Ratio  

(a)    Within ten (10) business days after May 31 and November 30 of each year beginning with
November 30, 2020 (such day, a “Reference Date,” and the tenth Business Day after a Reference Date, the “Certificate Delivery Date”), the Company will deliver to the Trustee an officer’s certificate demonstrating, with
reasonable detail the calculation of the Collateral Coverage Ratio with respect to such Reference Date and certifying that, the Collateral includes at least one category of Core Collateral as of such Reference Date. If (a) the Company fails to
deliver the officer’s certificate required by the preceding sentence within the time period specified in the preceding sentence, or (b) such officer’s certificate demonstrates that the Collateral Coverage Ratio was less than 1.6 to
1.00 with respect to the applicable Reference Date, then the Company will pay additional interest on all outstanding notes (“Special Interest”) in an amount equal to 2.0% per annum of the principal amount of such notes
commencing on the earlier of (x) the date the Company delivers an officer’s certificate demonstrating that its Collateral Coverage Ratio was less than 1.6 to 1.00 and (y) the date on which the Company was required to deliver such
officer’s certificate in accordance with this covenant, and continuing until the Company delivers to the Trustee an officer’s certificate demonstrating, with reasonably detailed calculations, that the Company’s Collateral Coverage
Ratio was at least 1.6 to 1.00 with respect to a date subsequent to the applicable Reference Date. If Special Interest would be payable on an Interest Payment Date within the Cure Period (as defined below), the Company may delay the payment of
Special Interest until the following Interest Payment Date (“Cure Election”). If the Company utilizes its Cure Election and during the Cure Period pledges Additional Collateral as First Lien Collateral or redeems, prepays or otherwise
retires Pari Passu Lien Debt during the applicable Cure Period such that the Collateral Coverage Ratio is greater than 1.6 to 1.00, then no Special Interest will be payable with respect to such Cure Period. If the Company fails to pledge Additional
Collateral or redeem or otherwise retire such debt during such Cure Period, Special Interest will be payable from the date specified in this paragraph on the next succeeding Interest Payment Date. 

(b)    If the Company’s Collateral Coverage Ratio is less than 1.6 to 1.00 with respect to any Reference Date, the
Company may, within 45 days after such Reference Date (such period, 

  
 81 













 
the “Cure Period”) (a) grant (or cause another Grantor to grant) a security interest in Additional Collateral as First Lien Collateral under the Security Documents and such Additional
Collateral will be included in the calculation of the Appraised Value of the First Lien Collateral with respect to such Reference Date and/or (b) redeem, repay, prepay, repurchase or otherwise retire Pari Passu Lien Debt, including by redeeming
Notes pursuant to any available provisions of Section 3.07 hereof and such redeemed, repaid, prepaid, repurchased or otherwise retired Pari Passu Lien Debt will not be included in the calculation of the Collateral Coverage Ratio with respect to
such Reference Date. 
 (c)    If, after the pledge of Additional Collateral as First Lien Collateral and/or any
redemption, repayment, prepayment, repurchase or other retirement of Pari Passu Lien Debt contemplated by the preceding paragraph and the recalculations of the Appraised Value of the First Lien Collateral or the Collateral Coverage Ratio pursuant to
clause (b) above, the Company’s Collateral Coverage Ratio with respect to the applicable Reference Date would have been at least 1.6 to 1.00, then the Company will be deemed to have a Collateral Coverage Ratio of at least 1.6 to 1.00 with
respect to such Reference Date, and no Special Interest will accrue with respect to such Reference Date. 
 (d)    If,
as of any Reference Date, it is determined that a Core Collateral Failure has occurred as a result of any event or circumstance other than a Disposition that is voluntary or a release of First Lien Collateral from the Pari Passu Lien of the
Collateral Trustee requested by the Company or any other Grantor, the Company shall, no later than forty-five (45) days after the date of such determination, either (A) grant (or cause a Grantor to grant) a security interest in Additional
Collateral such that following such grant the Collateral shall include at least one category of Core Collateral or (B) pay Special Interest as provided above. If, as of any Reference Date, it is determined that a Core Collateral Failure has
occurred as a result of a Disposition that is voluntary or a release of First Lien Collateral from the Pari Passu Lien of the Collateral Trustee requested by the Company or any other Grantor, it will be deemed to constitute a failure to comply with
a covenant or agreement as contemplated by clause (3) under Section 6.01 hereof. 
 (e)    Notwithstanding
anything herein to the contrary, neither (i) a Core Collateral Failure as a result of any event or circumstance other than the Disposition that is voluntary or release of First Lien Collateral from the Pari Passu Lien of the Collateral Trustee
requested by the Company or any other Grantor nor (ii) the Company’s failure to maintain a Collateral Coverage Ratio in excess of 1.6 to 1.00 will, in each case, be deemed to constitute an Event of Default for purposes of clause
(3) under Section 6.01 hereof (it being understood that the sole consequence of each thereof will be the payment of Special Interest, to the extent required by clause (a) above). 

(f)    If Special Interest is payable by the Company, the Company shall deliver to the Trustee an officer’s
certificate to that effect stating (i) the amount of such Special Interest that is payable and (ii) the date on which such Special Interest is payable. Unless and until a Responsible Officer of the Trustee receives such a certificate, the
Trustee may assume without inquiry that no such Special Interest is payable. Special Interest payable pursuant to the provisions of this Section 4.14 will be calculated and paid in the same manner as regular interest is calculated and paid
under this Indenture. 
 Section 4.15    Dispositions and Release of Collateral  

  
 82 













 (a)    At any time and from time to time, (x) the Company or any
other Grantor may Dispose of any First Lien Collateral, and (y) at the request of the Company or any other Grantor any First Lien Collateral may be released from the Pari Passu Lien of the Collateral Trustee for any reason (whether in
connection with a Disposition or otherwise); provided that with respect to (i) any Disposition of First Lien Collateral by the Company or any Grantor other than a Permitted Disposition or (ii) any release of First Lien Collateral from the
Pari Passu Lien of the Collateral Trustee requested by the Company or any Grantor, (A) no Event of Default shall have occurred and be continuing, (B) the Collateral Coverage Ratio, after giving pro forma effect to such Disposition or
release and any pledge of Additional Collateral and any repayment of Pari Passu Lien Debt, shall not be less than the Minimum CCR; and (C) the Company shall deliver an officer’s certificate to the Trustee and the Collateral Trustee
demonstrating compliance with such Collateral Coverage Ratio, and certifying that the Collateral includes at least one category of Core Collateral. 

(b)    The Company or any other Grantor may Dispose of the Second Lien Collateral, and the Company or any other Grantor
may request that the Second Lien Collateral be released from the Pari Passu Lien of the Collateral Trustee, only (i) pursuant to Section 2.04(b) of the Second Lien Intercreditor Agreement or (ii) to the extent such Disposition
constitutes a Permitted Disposition. 
 Section 4.16    Regulatory Cooperation 

(a)    In connection with any foreclosure, collection, sale or other enforcement pursuant to the Security Documents of the
Liens with respect to pledged Route Authorities, pledged Slots and pledged Foreign Gate Leaseholds granted to the Collateral Trustee in the Security Documents, Parent will, and will cause its Restricted Subsidiaries (x) to reasonably cooperate
in good faith with the Collateral Trustee in transferring the right to use such pledged Route Authorities, pledged Slots and pledged Foreign Gate Leaseholds to any designee of the Collateral Trustee that is an air carrier or any other Person
otherwise permitted to hold and use properties or rights such as the pledged Route Authorities, pledged Slots or pledged Foreign Gate Leaseholds and (y) as necessary (or at the reasonable request of the Collateral Trustee) and in good faith, to
continue to operate and manage such Collateral and maintain all applicable regulatory licenses with respect to such Collateral until such time as such designee obtains such licenses and governmental approvals as may be necessary or (in the
reasonable opinion of the Collateral Trustee or its designee specified above) advisable to conduct aviation operations with respect to such Collateral. 

Section 4.17    Regulatory matters; citizenship; utilization; reporting  

(a)    So long as any of the Notes remain outstanding, and, in each case, except as would not reasonably be expected to
have a Material Adverse Effect and, as applicable, subject to dispositions permitted under this Indenture, the Company will: 

(1)    maintain at all times its status as an “air carrier” within the meaning of
Section 40102(a)(2) of Title 49, and hold or co-hold a certificate under Section 41102(a)(1) of Title 49; 

(2)    maintain at all times its status at the FAA as an “air carrier” and hold or co-hold an air carrier operating certificate under Section 44705 of Title 49 and operations 

  
 83 













 
specifications issued by the FAA pursuant to Parts 119 and 121 of Title 14 as currently in effect or as may be amended or recodified from time to time; 

(3)    possess and maintain all necessary certificates, exemptions, franchises, licenses, permits,
designations, authorizations, frequencies and consents required by the FAA, the DOT or any applicable foreign aviation authority or airport authority or any other governmental authority that are material to the operation of the pledged Route
Authority and pledged Slots, and to the conduct of its business and operations as currently conducted, in each case, to the extent necessary for the Company’s operation of the Scheduled Services; 

(4)    maintain pledged Foreign Gate Leaseholds sufficient to ensure its ability to operate the Scheduled
Services and to preserve its right in and to its pledged Slots; 
 (5)    utilize its pledged Slots in a
manner consistent with applicable regulations, rules, foreign law and contracts in order to preserve its right to hold and use its pledged Slots, taking into account any waivers or other relief granted to it by the FAA, the DOT, any foreign aviation
authority or any airport authority; 
 (6)    cause to be done all things reasonably necessary to
preserve and keep in full force and effect its rights in and to use its pledged Slots, including, without limitation, satisfying any applicable “Use or Lose Rule” (taking into account any waivers, exemptions or other relief granted by the
relevant governmental authority or airport authority); 
 (7)    utilize its pledged Route Authorities in
a manner consistent with Title 49, applicable foreign law, the applicable rules and regulations of the FAA, DOT and any applicable foreign aviation authorities, and any applicable treaty in order to preserve its rights to operate the Scheduled
Services; 
 (8)    cause to be done all things reasonably necessary to preserve and keep in full force
and effect its authority to operate the Scheduled Services; and 
 (9)    without in any way limiting the
foregoing, the Company will promptly take all such steps as may be reasonably necessary to obtain renewal of its authority to serve its pledged Route Authorities from the DOT and any applicable foreign aviation authorities, in each case to the
extent necessary to operate the Scheduled Services, within a reasonable time prior to the expiration of such authority (as prescribed by law or regulation, if any), and promptly notify the Trustee if it has been informed that such authority will not
be renewed. 
 (b)    The Company will pay any applicable filing fees and other expenses related to the submission of
applications, renewal requests, and other filings as may be reasonably necessary to maintain or obtain its rights in its pledged Route Authorities and have access to its pledged Foreign Gate Leaseholds. 

(c)    Notwithstanding any of the foregoing, it is understood and agreed that (i) any Disposition of Collateral
permitted by this Indenture shall be permitted by provisions described above, (ii) nothing shall restrict or prohibit or require the Company or any Guarantor to contest 

  
 84 













 
any retiming or other adjustment of the time or time period for landing or takeoff or any adjustment with respect to terminal access or seating capacity, in each case, with respect to any pledged
Slot (whether accomplished by modification, substitution or exchange) for which no consideration is received by the Company or any of its Affiliates; provided that any other Slot received by the Company or any of its Affiliates in connection
with any such retiming or other adjustment of the time or time period for landing or takeoff with respect to any pledged Slot shall not constitute consideration and (iii) neither the Company nor any other Grantor shall have any obligation to
contest the application of, challenge the interpretation of, or take or refrain from taking any action to influence the enactment or the implementation of any legislation, regulation, policy or other action of the FAA, the DOT, any applicable
foreign aviation authority, airport authority or any other governmental authority that affects the existence, availability or value of properties or rights of the same type as the Route Authority, Slots, or Foreign Gate Leaseholds to air carriers
generally (and not solely to the Company or solely to any applicable Grantor), including any such legislation, regulation, policy or action relating to the applicability of Foreign Slots or FAA Slots to flight operations at any airport. 

Section 4.18    Additional Priority Lien Core Collateral 

If any Grantor grants a Priority Lien in any “Core Collateral” (as defined in the 2014 Credit Agreement) to the Priority Lien
Collateral Agent after the Closing Date pursuant to any Priority Lien Security Document, such Grantor shall, within forty-five (45) days thereafter, grant a second lien for the benefit of the Notes in such “Core Collateral” in favor
of the Collateral Trustee (unless such grant in favor of the Collateral Trustee would cause a Collateral Conflict). 
 ARTICLE 5 

SUCCESSORS 

Section 5.01    Merger and Sales of Assets. 

(a)    The Company and the Parent may consolidate with or merge into, or convey, transfer or lease all or substantially

applicable obligations under the Security Documents, the Notes and this Indenture (in the case of the Company) or the obligations under the applicable Note Guarantee (in the case of the Parent); 

(2)    except in connection with any Airlines Merger, immediately after giving effect to such transaction,
no Event of Default shall have occurred and be continuing; and 
 (3)    the Company shall have delivered
to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that such consolidation, merger or transfer and such supplemental indenture (if any) complies with this Indenture. 

  
 85

may exercise every right and power of, the Company or the Parent, whichever is party to such transaction, under this Indenture, but the predecessor issuer, in the case of a lease of all or substantially all of its assets, shall not be released from
the obligation to pay the principal of and interest on the Notes.

and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor person has been named as the Company herein; provided, however, that the predecessor Company in the case of a sale,
conveyance or other disposition (other than a lease) shall be released from all obligations and covenants under this Indenture and the Notes.

(7)    (a) any Security Document ceases to be in full force and effect (except as permitted by the terms of
this Indenture or the Security Documents or other than as a result of any action, inaction or delay of the Collateral Trustee or any Secured Debt Representative) for a period of 60 consecutive days after the Company receives notice specified below,
or (b) any of the Security Documents ceases to give the holders a valid, perfected (subject to Permitted Liens) security interest (except as permitted by the terms of this Indenture or the Security Documents or other than as a result of any

A Default under clause (3) or (7) of this Section 6.01 shall not constitute an Event of Default until the Trustee notifies the
Company or the Holders of at least 25% in principal amount of the outstanding Notes notify the Company and the Trustee of the Default and the Company does not cure such Default within 60 days after receipt of such notice. 

The term “Bankruptcy Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law. 
 Section 6.02    Acceleration. 

If an Event of Default occurs and is continuing (other than an Event of Default referred to in Section 6.01(5) or Section 6.01(6)),
then in every such case the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes may declare the principal amount of and accrued and unpaid interest, if any, on all of the Notes to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount and accrued and unpaid interest, if any, shall become immediately due and payable. If an Event of Default specified in
Section 6.01(5) or 6.01(6) shall occur, the principal amount of and accrued and unpaid interest, if any, on all outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder. 
 At any time after such a declaration of acceleration with respect to any Notes has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article 6, the Holders of a majority in principal amount of the outstanding Notes, by written notice to the Company and the Trustee, may
rescind and annul such declaration of acceleration and its consequences if the recession would not conflict with any judgment or decree and if all Events of Default with respect to Notes, other than the
non-payment of the principal and interest, if any, of Notes which have become due solely by such declaration of 

  
 88 













 
acceleration, have been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereon. 

Without limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior
to their stated maturity, in each case, in respect of any Event of Default (including an Event of Default under clause (5) or (6) of Section 6.01 hereof) (each an “Acceleration Event”), the Applicable Premium with respect to an
optional redemption of the Notes shall also be due and payable as though the Notes had been optionally redeemed in full at the time of such Acceleration Event and shall constitute part of the Obligations payable to Holders of the Notes in view of
the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Holder’s loss as a result thereof. If the Applicable Premium becomes due and payable, it
shall be deemed to be principal of the Notes, and interest shall accrue on the full principal amount of the Notes (including the Applicable Premium) from and after the applicable triggering event, including in connection with an Event of Default
under clause (5) or (6) of Section 6.01 hereof. Any Applicable Premium payable above shall be presumed to be the liquidated damages sustained by each Holder of the Notes as the result of the acceleration of the Notes and the Company agrees
that it is reasonable under the circumstances currently existing. The Applicable Premium shall also be payable in the event the Notes (and/or this Indenture) are satisfied, released or discharged by foreclosure (whether by power of judicial
proceeding or otherwise), deed in lieu of foreclosure or by any other similar means. THE COMPANY EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE
COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Company expressly agrees (to the fullest extent it may lawfully do so) that: (A) the Applicable Premium is reasonable and is the product of an arm’s length
transaction between sophisticated business people, ably represented by counsel; (B) the Applicable Premium shall be payable notwithstanding the then prevailing market rates at the time acceleration occurs; (C) there has been a course of
conduct between the Holders of the Notes and the Company giving specific consideration in this transaction for such agreement to pay the Applicable Premium; and (D) the Company shall be estopped hereafter from claiming differently than as
agreed to in this paragraph. The Company expressly acknowledges that its agreement to pay the Applicable Premium to the Holders of the Notes as herein described is a material inducement to the Holders to purchase the Notes. 

Section 6.03    Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if: 

(a)    default is made in the payment of any interest on any Notes when such interest becomes due and payable and such
default continues for a period of 30 days, or 
 (b)    default is made in the payment of principal of any Notes at the
Stated Maturity thereof, 
 then, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Notes, the whole
amount then due and payable on the Notes for principal and interest and, to 

  
 89 













 
the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and any overdue interest at the rate or rates prescribed therefor in the Notes, and, in
addition thereto, 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. 

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys
adjudged or deemed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

If an Event of Default with respect to the Notes occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Notes by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 

Section 6.04    Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise, 
 (a)    to file and prove a claim for the whole amount of principal and interest owing and
unpaid in respect of the Notes and to file such 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 of the Holders allowed in such judicial proceeding, and 
 (b)    to collect and
receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due 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 7.06. 

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 

  
 90 













 
or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.05    Trustee May Enforce Claims Without Possession of Notes. 

All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any
of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered. 

Section 6.06    Application of Money Collected. 

Any money or property collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by
the Trustee and, in case of the distribution of such money or property on account of principal or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

First: To the payment of all amounts due the Trustee under Section 7.06; and 

Second: To the payment of the amounts then due and unpaid for principal of and interest on the Notes in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest, respectively; and 

Third: To the Company. 

Section 6.07    Limitation on Suits. 

No Holder of any Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (a)    such Holder has previously
given written notice to the Trustee of a continuing Event of Default with respect to the Notes; 
 (b)    the Holders of
not less than 25% in principal amount of the outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(c)    such Holder or Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the
costs, expenses and liabilities which might be incurred by the Trustee in compliance with such request; 
 (d)    the
Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 

  
 91 













 (e)    no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the outstanding Notes; 

it being understood, intended and expressly covenanted by the Holder of every Note with every other Holder and the Trustee that no one or more of such Holders
shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders of the Notes (it being understood that the Trustee does not have an affirmative duty
to determine whether any direction is prejudicial to any holder of Notes). 
 Section 6.08    Unconditional
Right of Holders to Receive Principal and Interest. 
 Notwithstanding any other provision in this Indenture, the Holder of any Notes
shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest, if any, on the Notes on the Stated Maturity of the Notes, including the Stated Maturity expressed in the Notes (or, in the case of
redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

Section 6.09    Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 

Section 6.10    Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no
right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every
other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not, to the extent permitted by law, prevent the concurrent
assertion or employment of any other appropriate right or remedy. 
 Section 6.11    Delay or Omission Not
Waiver. 
 No delay or omission of the Trustee or of any Holder of the Notes to exercise any right or remedy accruing upon any Event of
Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by 

  
 92 













 
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

Section 6.12    Control by Holders. 

The Holders of a majority in principal amount of the outstanding Notes shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee for the Notes, or exercising any trust or power conferred on the Trustee with respect to the Notes; provided that: 

(a)    such direction shall not be in conflict with any rule of law or with this Indenture, 

(b)    the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction,

 (c)    subject to the provisions of Section 6.02, the Trustee shall have the right to decline to follow any such
direction if the Trustee in good faith shall, by a Responsible Officer of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability, and 

(d)    prior to taking any action as directed under this Section 6.12, the Trustee shall be entitled to indemnity
satisfactory to it in its sole discretion against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. 

Section 6.13    Waiver of Past Defaults. 

By notice to the Trustee, the Holders of a majority in aggregate principal amount of the Notes then outstanding may waive an existing Default
and its consequences except (i) a Default in the payment of the principal amount of, premium, if any, and accrued and unpaid interest on the Notes, (ii) a Default arising from the failure to redeem or purchase any Notes when required
pursuant to the terms of this Indenture or (iii) a Default in respect of a provision that under this Indenture cannot be amended without the consent of each Holder of the Notes affected. 

Section 6.14    Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Notes by his acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, 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, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding
in the aggregate more than 10% in principal amount of the outstanding Notes, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest on any Notes on or after the Stated Maturity of the Notes,

Section 7.01    Duties of Trustee. 

(a)    If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers

Trustee shall examine such Officer’s Certificates and Opinions of Counsel to determine whether or not they conform to the form requirements of this Indenture.

genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 

(b)    Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of

references the Notes and this Indenture. 
 (i)    In no event shall the Trustee be liable to any person for special,
punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage. 

(j)    The permissive right of the Trustee to take the actions permitted by this Indenture shall not be construed as an
obligation or duty to do so.

such Default or Event of Default. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or accrued and unpaid interest on the Notes, the Trustee may withhold the notice if and so long a Responsible Officer

Section 7.06    Compensation and Indemnity. 

The Company shall pay to the Trustee from time to time compensation for its services as the Company and the Trustee shall from time to time
agree upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out of pocket expenses incurred by it.
Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel. 
 The Company shall
indemnify each of the Trustee and any predecessor Trustee (including the cost of enforcement or defending itself) and hold it harmless against any cost, expense or liability, including taxes (other than taxes based upon, measured by or determined by
the income of the Trustee) incurred by it except as set forth in the next paragraph in the performance of its duties under this Indenture as Trustee or Agent. The Trustee shall notify the Company promptly of any third party claim for which it may
seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, unless and to the extent that the Company is materially prejudiced thereby. The Company shall defend the third party claim
and the Trustee shall cooperate in the defense. The Trustee may have one separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent
will not be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee. 

The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director,
employee, shareholder or agent of the Trustee through willful misconduct or negligence. 
 To secure the Company’s payment obligations
in this Section, 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 of and interest on the Notes. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(5) or (6) occurs, the
expenses and the compensation for the services are intended to constitute administrative expenses for purposes of priority under any Bankruptcy Law. 

The provisions of this Section shall survive the termination of this Indenture and resignation or removal of the Trustee. 

Section 7.07    Replacement of Trustee. 

  
 97 













 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. 
 The Trustee may resign with
respect to the Notes by so notifying the Company at least 30 days prior to the date of the proposed resignation. The Holders of a majority in principal amount of the Notes may remove the Trustee with respect to those Notes by so notifying the
Trustee and the Company at least 30 days prior to the date of the proposed removal. The Company may remove the Trustee with respect to the Notes if: 

(1)    the Trustee fails to comply with Section 7.09; 

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

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 

If a successor Trustee with respect to the Notes does not take office within 60 days after the retiring Trustee resigns or is removed, the
retiring Trustee (at the Company’s expense), the Company or the Holders of at least a majority in principal amount of the Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 7.06, the resignation or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee with respect to the Notes for which it is acting as Trustee under this Indenture. A successor Trustee shall mail a notice of its succession to each Holder of the Notes.
Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 hereof shall continue for the benefit of the retiring Trustee with respect to expenses and liabilities incurred by
it for actions taken or omitted to be taken in accordance with its rights, powers and duties under this Indenture prior to such replacement. 

Section 7.08    Successor Trustee by Merger, etc. 

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the successor Trustee, subject to Section 7.09. 

  
 98 













 Section 7.09    Eligibility; Disqualification. 

There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least
$100.0 million as set forth in its most recent published annual report of condition. 

Section 7.10    Limitation on Duty of Trustee in Respect of Collateral.  

(a)    Beyond the exercise of reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral
in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee shall not be responsible for
filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee shall
be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss
or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith. 

(b)    The Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the
validity, perfection, priority or enforceability of the Liens in any of the Collateral, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company to the
Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty to ascertain or inquire as to the performance
or observance of any of the terms of this Indenture, the Collateral Trust Agreement, the Security Documents or any other security documents by the Company, the Guarantors, or the Collateral Trustee. 

ARTICLE 8

(b)    the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

if money shall have been deposited with the Trustee pursuant to clause (a) of this Section, the provisions of Sections 2.03, 2.06, 2.07, 8.02 and 8.05 shall survive. 

Section 8.02    Application of Trust Funds; Indemnification. 

(a)    Subject to the provisions of Section 8.05, all money or Government Securities deposited with the Trustee
pursuant to Section 8.01, all money and Government Securities deposited with the Trustee pursuant to Section 8.03 or 8.04 and all money received by the Trustee in respect of Government Securities deposited with the Trustee pursuant to

 100 













 (c)    The Trustee shall deliver or pay to the Company from time to time
upon the Company’s request any Government Securities or money held by it as provided in Sections 8.03 or 8.04 which, in the opinion of a nationally recognized firm of independent certified public accountants expressed in a written certification
thereof delivered to the Trustee, are then in excess of the amount thereof which then would have been required to be deposited for the purpose for which such Government Securities or money were deposited or received. This provision shall not
authorize the sale by the Trustee of any Government Securities held under this Indenture. 

Section 8.03    Legal Defeasance of Notes. 

The Company shall be deemed to have paid and discharged the entire indebtedness on all the outstanding Notes on the 91st day after the date of
the deposit referred to in subparagraph (c)(1) hereof, and the provisions of this Indenture, as it relates to the Notes, shall no longer be in effect (and the Trustee, at the expense of the Company, shall, upon receipt of direction from the Company,
execute instruments acknowledging the same), except as to:

trust funds described in subparagraph (c)(1) hereof, payment of the principal of and interest on the outstanding Notes on the Stated Maturity of such principal or interest; 

(b)    the provisions of Sections 2.03, 2.06, 2.07, 8.02, 8.03 and 8.05; and

and/or Government Securities, which through the payment of interest and principal in respect thereof in accordance with their terms will provide (and without reinvestment and assuming no tax liability will be imposed on such Trustee), not later than
one day before the due date of any payment of money, an amount in cash, sufficient, in the opinion of a nationally recognized independent registered accounting firm expressed in a written certification thereof delivered to the Trustee, to pay and
discharge each installment of principal of, premium, if any, and interest, if any, on the Notes on the dates such installments of interest or principal are due; 

(2)    the Company shall have delivered an Officer’s Certificate and an Opinion of Counsel to the

income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit, defeasance and
discharge and will be subject to Federal income 

  
 101 













 
tax on the same amount and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred; 

(3)    no Event of Default shall have occurred and be continuing either: (x) on the date of such
deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit); or (y) with respect to Events of Default described in Section 6.01(5) and Section 6.01(6) or other bankruptcy, insolvency or
reorganization-related Events of Default, at any time in the period ending on the 91st day after the date of deposit; 

(4)    such defeasance will not result in a breach or violation of, or constitute a default under, this
Indenture or any other agreement or instrument to which the Company is a party or by which it is bound; 

(5)    the Company shall have delivered to the Trustee an Officer’s Certificate stating that the
deposit was not made by the Company with the intent of preferring the Holders of the Notes over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and

 (6)    the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel, each stating that all conditions precedent provided for relating to the defeasance contemplated by this Section have been complied with. 

Section 8.04    Covenant Defeasance. 

The Company may omit to comply with respect to the Notes with any term, provision or condition set forth under Sections 4.03, 4.07, 4.08,
4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18 and 5.01 as well as any additional covenants specified in a supplemental indenture for the Notes (and the failure to comply with any such covenants shall not constitute a Default or Event of
Default with respect to the Notes under Section 6.01) and the occurrence of any event specified in a supplemental indenture for the Notes and designated as an Event of Default shall not constitute a Default or Event of Default hereunder, with
respect to the Notes, provided that the following conditions shall have been satisfied:

to this Section 8.04, the Company has irrevocably deposited or caused to be irrevocably deposited (except as provided in Section 8.02(c)) with the Trustee as trust funds in trust for the purpose of making the following payments

 (b)    The Company shall have delivered to the Trustee an Opinion
of Counsel to the effect that Holders of the Notes will not recognize income, gain or loss for Federal income tax 

  
 102 













 
purposes as a result of such deposit and covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if
such deposit and covenant defeasance had not occurred; 
 (c)    No Event of Default shall have occurred and be
continuing either: (x) on the date of such deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit); or (y) with respect to Events of Default described in Section 6.01(5) and
Section 6.01(6) or other bankruptcy, insolvency or reorganization-related Events of Default, at any time in the period ending on the 91st day after the date of deposit;

Documents on behalf of the holders of the Notes and the Collateral will no longer secure the Notes. 

Section 8.05    Repayment to Company. 

Subject to applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them
for the payment of principal, premium, if any, and interest that remains unclaimed for two years. After that, Holders of Notes entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property
law designates another person. 
 Section 8.06    Reinstatement. 

If the Trustee or the Paying Agent is unable to apply any money deposited with respect to Holders of Notes in accordance with
Section 8.01 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 obligations of the Company under this Indenture
with respect to Holders of Notes and under the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in
accordance with Section 8.01; provided, however, that if the Company has made any payment of principal of, premium, if any, or interest on the Notes because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of the Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent after payment in full to the Holders. 

  
 103 













 ARTICLE 9 

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 9.01    Without Consent of Holders of Notes. 

The Company, the Guarantors and the Trustee and the Collateral Trustee, as applicable, may amend or supplement this Indenture or the Security
Documents as they apply to the Notes without the consent of any Holder: 
 (a)    to evidence the succession of another
Person to the Company or the Parent pursuant to Section 5.01 and the assumption by such successor of the Company’s or the Parent’s covenants, agreements and obligations under this Indenture and with respect to the Notes; 

(b)    to surrender any right or power conferred upon the Company or the Parent; 

(c)    to add to the covenants such further covenants, restrictions, conditions or provisions for the protection of the
Holders of the Notes, and to add any additional Events of Default for the Notes for the benefit of the Holders of the Notes; provided, however, that with respect to any such additional covenant, restriction, condition or provision,
such amendment may provide for a period of grace after Default, which may be shorter or longer than that allowed in the case of other Defaults, may provide for an immediate enforcement upon such Default or may limit the right of Holders of a
majority in aggregate principal amount of the Notes to waive such Default; 
 (d)    to cure any ambiguity or correct or
supplement any provision contained in this Indenture, in any supplemental indenture, Officer’s Certificate or in the Notes that may be defective or inconsistent with any other provision contained herein or therein; 

(e)    to convey, transfer, assign, mortgage or pledge any property to or with the Trustee, or to make such other
provisions in regard to matters or questions arising under this Indenture as shall not adversely affect the interests of any Holder of the Notes; 

(f)    to modify or amend this Indenture in such a manner as to permit the qualification of this Indenture or any
supplemental indenture under the TIA as then in effect; 
 (g)    to add to or change any provisions of this Indenture
to such extent as necessary to permit or facilitate the issuance of the Notes in bearer or uncertificated form, provided that any such action shall not adversely affect the interests of any Holder of the Notes in any material respect; 

(h)    to provide additional security for the Notes; 

(i)    to provide additional guarantees for the Notes; 

(j)    to make changes of a technical or conforming nature to the Collateral Trust Agreement, any intercreditor agreement,
or any other Security Document, in each case in connection with (i) the incurrence of Indebtedness (including secured Indebtedness) or other obligations permitted to be incurred in accordance Section 4.08 herein or (ii) any
Disposition or release of Collateral permitted in accordance with Section 4.15 herein. 

  
 104 













 (k)    to make any change that does not adversely affect the rights of
any Holder of the Notes; or 
 (l)    to evidence and provide for the acceptance of appointment of a separate or
successor trustee and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of this Indenture by more than one trustee. 

In addition, the Security Documents may be amended in accordance with (i) Article 11 hereof, (ii) Section 4.1 of the Collateral
Trust Agreement and (iii) Section 7.04 of the Second Lien Intercreditor Agreement (or the corresponding provisions of any comparable intercreditor agreement entered into pursuant to Section 11.03 hereof).     

Section 9.02    With Consent of Holders of Notes. 

The Company and the Trustee and the Collateral Trustee, as applicable, may enter into (or provide any applicable consent to) a supplemental
indenture or amend or supplement the Security Documents as they apply to the Notes with the written consent of the Holders of at least a majority in principal amount of the outstanding Notes (including consents obtained in connection with a tender
offer or exchange offer for the Notes) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of a Security Document, this Indenture or of any supplemental indenture or of modifying in any manner
the rights of the Notes. Except as provided in Section 6.13, the Holders of at least a majority in principal amount of the outstanding Notes by notice to the Trustee (including consents obtained in connection with a tender offer or exchange
offer for Notes) may waive compliance by the Company with any provision of this Indenture or the Notes. 
 Without the consent of each
Holder of an affected Note, an amendment may not: 
 (a)    make any change to the percentage of principal amount of
Notes the Holders of which must consent to an amendment or waiver; 
 (b)    reduce the principal amount of, premium, if
any, or interest on, or extend the Stated Maturity or interest payment periods, of the Notes; 
 (c)    make the Notes
of such Holder payable in money or securities other than that as stated in the Notes; 
 (d)    make any change that
adversely affects such Holder’s right to require the Company to purchase the Notes of such Holder in accordance with the terms of this Indenture; 

(e)    impair the right of such Holder to institute suit for the enforcement of any payment with respect to the Notes;

 (f)    except pursuant to the provisions of Article 8 hereto or in connection with a consolidation, merger or

 105 













 (g)    make any change in the provisions of this Indenture relating to
waiving an existing Default or to the right to receive payment of, or bring suit to enforce payments of, the principal amount of, premium, if any, or interest on the Notes; or 

(h)    modify any of the foregoing provisions of this Section 9.02. 

Any amendment to, or waiver of, the provisions of this Indenture or any Security Document that has the effect of releasing all or
substantially all of the Collateral from the Liens securing the Notes (other than in compliance with Section 11.05 of this Indenture) will require the consent of holders of at least 75% in aggregate principal amount of notes then outstanding.

 It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any
proposed supplemental indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this section becomes effective, the Company shall mail to the Holders of Notes, a
notice briefly describing the supplemental indenture or waiver. Any failure by the Company to mail or publish such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or
waiver. 
 Section 9.03    Revocation and Effect of Consents. 

Until an amendment is set forth in a supplemental indenture or a waiver becomes effective, a consent to it by a Holder of the Notes is a
continuing consent by the Holder and every subsequent Holder the Notes or portion of a Note that evidences the same debt as the consenting Holder’s Notes, even if notation of the consent is not made on any Notes. However, any such Holder or
subsequent Holder may revoke the consent as to his Notes or portion of a Note if the Trustee receives the notice of revocation before the date of the supplemental indenture or the date the waiver becomes effective. 

Any amendment or waiver once effective shall bind every Holder of the Notes affected by such amendment or waiver unless it is of the type set
forth in any of clauses (a) through (h) of Section 9.02. In that case, the amendment or waiver shall bind each Holder of the Notes who has consented to it and every subsequent Holder of the Notes or portion of a Notes that evidences the
same debt as the consenting Holder of the Notes. 
 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 take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 

Section 9.04    Notation on or Exchange of Notes. 

  
 106 













 The Company or the Trustee may place an appropriate notation about an amendment or waiver on
the Notes thereafter authenticated. The Company in exchange for Notes may issue and the Trustee shall authenticate upon request new Notes that reflect the amendment or waiver. 

Section 9.05    Trustee Protected. 

In executing, consenting to or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the
modifications thereby of the trusts created by this Indenture or the Security Documents, as applicable, the Trustee and the Collateral Trustee, as applicable, shall be entitled to receive, and (subject to Section 7.01) shall be fully protected
in relying upon, an Officer’s Certificate or an Opinion of Counsel or both complying with Section 12.02. The Trustee or Collateral Trustee, as applicable, shall sign all amendments supplemental indentures upon delivery of such an
Officer’s Certificate or Opinion of Counsel or both, except that the Trustee or the Collateral Trustee, as applicable, need not sign any supplemental indenture that adversely affects its rights, obligations, indemnities or immunities. 

ARTICLE 10 
 NOTE GUARANTEES 

Section 10.01    Note Guarantees. 

(a)    Subject to the provisions of this Article 10, each Guarantor hereby fully, unconditionally and irrevocably
guarantees, as primary obligor and not merely as surety, on a joint and several basis, to each Holder of the Notes and the Trustee the due and punctual payment of the principal of (and premium, if any) and interest (including, in case of default,
interest on principal and, to the extent permitted by applicable law, on overdue interest and including any additional interest required to be paid according to the terms of the Notes), if any, on the Notes, when and as the same shall become due and
payable, whether at Stated Maturity, upon redemption, upon acceleration, upon tender for repayment at the option of any Holder or otherwise, according to the terms thereof and of this Indenture and all other obligations of the Company with respect
to the Notes to any Holder or the Trustee hereunder or thereunder. Each Guarantor agrees that the Guarantor Obligations will rank equally in right of payment with other Indebtedness of such Guarantor, except to the extent such other Indebtedness is
subordinate to the Guarantor Obligations, in which case the obligations of the Guarantors under the Note Guarantees will rank senior in right of payment to such other Indebtedness, and except for claims of creditors that are mandatorily preferred by
law, in which case the obligations of the Guarantors under the Note Guarantees will rank junior in right of payment to such claims. 

(b)    To evidence its Note Guarantee set forth in this Section 10.01, each Guarantor hereby agrees that this
Indenture (or a supplement thereto, substantially in the form attached as Exhibit F hereto) and, in the case of additional Guarantors added pursuant to Section 9.01(i) hereof, a supplement to the Note Guarantee, substantially in the form
attached as Exhibit E hereto shall be executed on behalf of such Guarantor by an Officer of such Guarantor. 

(c)    Each Guarantor hereby agrees that its Note Guarantee set forth in this Section 10.01 hereof shall remain in
full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes. 

  
 107 













 (d)    If an Officer whose signature is on this Indenture (or a
supplement thereto) or any notation of Guarantee no longer holds that office at the time the Trustee authenticates a Note, the Note Guarantee of such Note shall be valid nevertheless. 

(e)    Each Guarantor further agrees (to the extent permitted by law) that the Guarantor Obligations may be extended or
renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Section 10.01 notwithstanding any extension or renewal of any Guarantor Obligation. 

(f)    Each Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guarantor
Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guarantor Obligations. 

(g)    Each Guarantor further agrees that its Note Guarantee herein constitutes a guarantee of payment when due (and not a
guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guarantor Obligations. 

(h)    Except as set forth in Section 10.04, the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason (other than payment of the Guarantor Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of
setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guarantor Obligations or otherwise. Without limiting the generality of the foregoing, the Guarantor Obligations of each
Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other person under this Indenture, the Notes
or any other agreement or otherwise; (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at Stated Maturity, by acceleration or otherwise; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of
any security held by any Holder for the Guarantor Obligations; (e) the failure of any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the ownership of the Company; (g) any default, failure or
delay, willful or otherwise, in the performance of the Guarantor Obligations or (h) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or
would otherwise operate as a discharge of such Guarantor as a matter of law or equity. 
 (i)    Each Guarantor agrees
that its Note Guarantee herein shall remain in full force and effect until payment in full of all the Guarantor Obligations or such Guarantor is released from its Note Guarantee in compliance with Section 5.01 or Section 8.01 hereof. Each
Guarantor further agrees that its Note Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, or interest on any of the Guarantor
Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise. 

  
 108 













 (j)    In furtherance of the foregoing and not in limitation of any
other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay any of the Guarantor Obligations when and as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee on behalf of the Holders an amount equal to the sum of
(i) the unpaid amount of such Guarantor Obligations then due and owing and (ii) accrued and unpaid interest on such Guarantor Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after
the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Company or any Guarantor whether or not a claim for postfiling or post-petition interest is allowed in such
proceeding). 
 (k)    Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders,
on the other hand, (x) the maturity of the Guarantor Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Note Guarantee herein, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Guarantor Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guarantor Obligations, such Guarantor Obligations (whether or not due and payable) shall
forthwith become due and payable by such Guarantor for the purposes of this Note Guarantee. 
 (l)    Each Guarantor
also agrees to pay any and all fees, costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under this Section 10.01. 

(m)    Any Guarantor may, but shall not be required to be, a Grantor in accordance with Section 11.04. 

Section 10.02    Right of Contribution. 

Each Guarantor hereby agrees that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made on
the obligations under the Note Guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Company or any other Guarantor who has not paid its proportionate share of such payment. The provisions of this
Section 10.02 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor
hereunder. 
 Section 10.03    No Subrogation. 

Notwithstanding any payment or payments made by any Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights
of the Trustee or any Holder against the Company or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Guarantor Obligations, nor shall any Guarantor seek or be
entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Guarantor
Obligations are paid in 

  
 109 













 
full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Guarantor Obligations shall not have been paid in full, such amount shall be
held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly
indorsed by such Guarantor to the Trustee, if required), to be applied against the Guarantor Obligations. 

Section 10.04    Limitation of Guarantor’s Liability. 

Each Guarantor and, by its acceptance of a Note, each Holder of a Note hereby confirms that it is the intention of all such parties that in no
event shall any Guarantor Obligations under the Note Guarantees constitute or result in a fraudulent transfer or conveyance for purposes of, or result in a violation of, any United States federal, or applicable United States state, fraudulent
transfer or conveyance or similar law. To effectuate the foregoing intention, in the event that the Guarantor Obligations, if any, in respect of the Notes would, but for this sentence, constitute or result in such a fraudulent transfer or conveyance
or violation, then the liability of the applicable Guarantor under its Note Guarantee in respect of the Notes shall be reduced to the extent necessary to eliminate such fraudulent transfer or conveyance or violation under the applicable fraudulent
transfer or conveyance or similar law. 
 ARTICLE 11 

COLLATERAL AND SECURITY 

Section 11.01    Security Interest. 

The due and punctual payment of the principal of, premium (if any), interest and Special Interest, if any, on, the Notes when and as the same
shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium (if any), interest and Special Interest, if any, on the Notes and
performance of all other obligations of the Company to the Holders of Notes, the Collateral Trustee or the Trustee, according to the terms hereunder or thereunder, are secured as provided in the Security Documents. 

Section 11.02    Collateral Trust Agreement; Authorization of Security Documents. 

This Article 11 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the Collateral
Trust Agreement. Each of the parties hereto consents to, and agrees to be bound by, the terms of the Collateral Trust Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms
therewith. The Trustee, the Parent and the Company hereby acknowledge and agree that the Collateral Trustee holds the Collateral in trust for the benefit of the Secured Parties, in each case pursuant and subject to the terms of the Collateral Trust
Agreement, the Second Lien Intercreditor Agreement, and the other Security Documents (including any other security documents, intercreditor agreements or collateral trust agreement entered into after the date hereof in accordance with
Section 11.03). Each Holder, by its acceptance of a Note, authorizes and appoints (and authorizes the Trustee to authorize and appoint) Wilmington Trust, National Association, as the Collateral Trustee, and the Trustee hereby authorizes and
appoints Wilmington 

  
 110 













 
Trust Company as Collateral Trustee. In addition, each Holder, by its acceptance of a Note, consents and agrees to the terms of the Collateral Trust Agreement, the Second Lien Intercreditor
Agreement, the First Lien Security Agreement, the Second Lien Security Agreement, the UK Debenture and such other Security Documents (including such other security documents, intercreditor agreements or collateral trust agreements entered into after
the date hereof in accordance with Section 11.03), in each case as the same may be in effect or may be amended, supplemented, waived or otherwise modified from time to time in accordance with their terms and the terms of this Indenture, and
authorizes and directs the Trustee and the Collateral Trustee, as applicable, to enter into each such document and to perform its obligations and exercise its rights thereunder, together with such actions and powers as are reasonably incidental
thereto, in accordance therewith (including the provisions of the Security Documents providing for the possession, use, release and foreclosure of Collateral and the ranking, priority, enforcement and release of Liens). 

Section 11.03    Additional Security Documents.  

In connection with any incurrence after the Closing Date of Indebtedness secured by a Lien, which Indebtedness and Lien are not prohibited by
Section 4.08 or Section 4.12 (including, without limitation, any Indebtedness secured by (i) a Pari Passu Lien, (ii) a Junior Lien, (iii) a Priority Lien on the Second Lien Collateral, (iv) a lien (other than a Junior
Lien) that is junior to the Pari Passu Liens on the First Lien Collateral, (v) a lien that is junior to the Pari Passu Liens on the Second Lien Collateral, (vi) a Lien on assets not constituting Collateral or (vii) any combination of
the foregoing (provided, that no Indebtedness may, with respect to the First Lien Collateral, be designated as both Pari Passu Lien Debt and Junior Lien Debt), in the case of each of clauses (i)-(vii), to the extent not prohibited by
Section 4.08 or Section 4.12), the Company may direct the Collateral Trustee to enter into an intercreditor agreement (or an amendment or amendment and restatement or replacement of any prior intercreditor agreement, including, without
limitation, the Second Lien Intercreditor Agreement) with the administrative agent, trustee, collateral agent or other party acting as agent for such Indebtedness, which intercreditor agreement (or amendment or amendment and restatement or
replacement) will be based on a form of intercreditor agreement entered into in connection with the Company’s other secured financing, with such changes as are necessary or desirable (as determined by the Company in its discretion) in order to
implement the applicable security and intercreditor arrangements relating to such Indebtedness. In addition, in connection with any pledge of, or grant of a security interest in, any additional collateral for the benefit of the Notes and/or other
Pari Passu Lien Debt Obligations (including, without limitation, any Additional Collateral), the Company may direct the Collateral Trustee to enter into such additional security documents (or amendments or amendment and restatements of existing
security documents), in the Company’s customary form for the applicable collateral (as determined by the Company in its discretion), as are necessary or desirable to effect such pledge or grant. The Company will deliver an Officer’s
Certificate and Opinion of Counsel to the Trustee and/or the Collateral Trustee, as applicable, prior to the Trustee and/or the Collateral Trustee, as the case may be, taking any action pursuant to this Section 11.03. 

Section 11.04    Additional Grantors  

At any time and from time to time, the Parent or any other Subsidiary (other than the Company) may, but shall not be required to, provide
additional collateral for the benefit of the 

  
 111 













 
Notes and/or other Pari Passu Lien Debt Obligations. In such event, Parent or such Subsidiary shall execute a supplement indenture hereto, and shall thereafter be a “Grantor” (or
comparable term) for all purposes under the Security Documents. An additional Grantor pursuant to this Section 11.04 may, but shall not be required to, guarantee the Notes. For avoidance of doubt, as of the date of this Indenture, the Parent is
not a Grantor, and all of Parent’s obligations under this Indenture and its guarantee of the Notes are general senior unsecured obligations of Parent. 

Section 11.05    Release of Liens in Respect of the Notes. 

The Collateral Trustee’s Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any other
Obligations under this Indenture, and the right of the Holders of Notes and such Obligations to the benefits and proceeds of the Collateral Trustee’s Liens on the Collateral will automatically terminate and be discharged: 

(a)    upon satisfaction and discharge of this Indenture in accordance with Article 8 hereof; 

(b)    upon a Legal Defeasance or Covenant Defeasance of the Notes in accordance with Article 8 hereof; 

(c)    upon payment in full and discharge of all Notes outstanding under this Indenture and all Obligations that are
outstanding, due and payable under this Indenture at the time the Notes are paid in full and discharged; or 
 (d)    in
whole or in part, with the consent of the Holders of the requisite percentage of Notes in accordance with Article 9 hereof. 

(e)    with respect to any Guarantor, upon any disposition of 50% or more of the Capital Stock of such Guarantor such that
it is no longer a Restricted Subsidiary to the extent not prohibited by the terms of this Indenture. 
 In addition, the Collateral
Trustee’s Liens on the Collateral will be released upon the terms and subject to the conditions set forth in Section 4.1 of the Collateral Trust Agreement and Section 2.04(b) of the Second Lien Intercreditor Agreement (or the
comparable provisions of any other intercreditor agreement entered into pursuant to Section 11.03 hereof).

Section 12.06    Governing Law; Jurisdiction; Waiver of Jury Trial. 

THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES WITHOUT

the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York (collectively, the “Specified Courts”), and each party
irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail (to the extent allowed under any

suit, action or other proceeding has been brought in an inconvenient forum.

from time to time, or other applicable law) of this Indenture shall have the same validity and effect as a signature affixed by the party’s hand; provided that, notwithstanding anything herein to the contrary, the Trustee is not under
any obligation to agree to accept electronic signatures in any form or in any format unless agreed to by it pursuant to reasonable procedures approved by such parties. 

Section 12.11    Table of Contents, Headings, etc.

such date.

The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all financial
institutions, in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a relationship or opens an account with the

sabotage, epidemics, riots, labor disputes, civil unrest, local or national disturbance or disaster, any act of terrorism, or the unavailability of the Federal Reserve Bank wire or facsimile or
other wire or communication facility), it being understood that the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

 Section 12.15    Collateral Trustee and Collateral Trust Agreement.  

(a)    The Collateral Trustee shall be an express third party beneficiary and shall enjoy the rights, protections,
immunities, and indemnities afforded the Trustee hereunder; provided the foregoing shall not be construed to impose on the Collateral Trustee the duties or standard of care (including any prudent person standard) of the Trustee. 

(b)    In connection with any matter under the Collateral Trust Agreement requiring a vote of Holders of Notes, except as
may be provided by Article 9 or as may otherwise be expressly provided hereunder, the Trustee will cast a vote under the Collateral Trust Agreement on behalf of all the Holders as a block in the manner directed by Holders of a majority in aggregate
principal amount of the Notes then outstanding. 
 (c)    If at any time the Trustee receives notification from the
Collateral Trustee of a vote conducted pursuant to the terms of the Collateral Trust Agreement, and this Indenture does not otherwise expressly provide the manner in which the Trustee should act in respect of such vote, the Trustee shall notify the
Holders of such vote and request instructions from the Holders as to such vote. In respect of Global Notes, the Trustee shall be fully protected in providing such notice to DTC in accordance with the applicable procedures at DTC (including by
sending all such notices to legalandtaxnotices@dtcc.com, provided that that Trustee may, in its discretion, cause such notice to be processed through the DTC’s Automated Tender Offer Program procedures or any successor thereto). The Trustee
will have no responsibility or liability for the terms or requirements of any such systems or procedures offered by DTC, or any unavailability thereof. Except in circumstances expressly provided in this Indenture, the Trustee may refrain from voting
(or otherwise providing directions to the Collateral Trustee) and shall have no liability for any such failure to provide such vote to the Collateral Trustee (or otherwise providing directions to the Collateral Trustee) in the absence of direction
from Holders of a majority in aggregate principal amount of the Notes then outstanding.

 11.75% Senior
Secured Notes due 2025 
 1.    INTEREST. American Airlines, Inc., a Delaware
corporation (the “Company”), promises to pay or cause to be paid interest on the principal amount of this Note at 11.75% per annum from
                    ,                  until maturity

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 the first Interest Payment Date shall be                 ,
                . The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that

of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 
 Interest will be computed on

due. 
 2.    METHOD OF PAYMENT. The Company will pay
interest on the Notes (except defaulted interest), if any, to the Persons who are registered Holders of Notes at the close of business on the January 1 and July 1 next preceding the Interest Payment Date, even if the Notes are canceled
after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the
office or agency of the Paying Agent and Registrar, or, at the option of the Company, payment of interest, if any, 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, premium on, if any, and interest, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the
Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

 5.    OPTIONAL REDEMPTION; CHANGE

 a.    The Notes will be redeemable, at the
Company’s option, in whole at any time or in part from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining
scheduled payments of principal and interest (including Special Interest, if any) on such Notes (excluding accrued and unpaid interest (including Special Interest, if any) to the redemption date) discounted to the redemption date on a semiannual
basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, plus, in the case of either the preceding clause
(1) or (2), accrued and unpaid interest on the principal amount of Notes being redeemed to (but not including) such redemption date (subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant

b.    Upon the occurrence of a Change of Control, each Holder of Notes will have the right to require the Company to
repurchase all or any part (equal to a minimum denomination of $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to a Change of Control Offer at a purchase price in cash equal to 101% of the aggregate
principal amount of the Notes repurchased, plus accrued and unpaid interest on the Notes repurchased to (but not including) the date of purchase. 

c.    If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not
withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the
Company or such third party will have the right, upon not less than 10 days nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes
that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but not including) the redemption date. 

6.    MANDATORY REDEMPTION. The Company is not required to make
mandatory redemption or sinking fund payments with respect to the Notes. 
 7.    NOTICE
OF REDEMPTION. At least 10 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first-class mail, 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 the
Indenture pursuant to Article 8 thereof. Notes and portions of Notes selected will be in principal amounts of $2,000 or integral multiples of $1,000 in excess thereof; except that if all of the 

  
 A - 3 













 EXHIBIT A 

Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. 

Any such redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including the consummation of a
Change of Control. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or
all such conditions shall be satisfied or waived, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption
date so delayed. 
 8.    DENOMINATIONS, TRANSFER,
EXCHANGE. The Notes are in registered form in denominations of $2,000 and integral multiples of $1,000 in excess 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 and the Company may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company need not exchange or register the transfer of 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 need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the next succeeding Interest Payment Date. 

9.    PERSONS DEEMED OWNERS. The registered Holder of a
Note may be treated as the owner of it for all purposes. Only registered Holders have rights under the Indenture. 

10.    AMENDMENT, SUPPLEMENT AND WAIVER.
The provisions governing amendment, supplement and waiver of any provision of the Indenture, the Notes or the Note Guarantees are set forth in Article 9 of the Indenture. 

11.    DEFAULTS AND REMEDIES. The Events of Default
relating to the Notes and related remedies and other provisions are included in Section 6.01 of the Indenture. 

12.    SECURITY. The Notes shall be secured by Liens and security
interests, subject to Permitted Liens, in the Collateral. The Collateral Trustee holds the Collateral in trust for the benefit of the Trustee and the Holders, in each case pursuant to the Security Documents. 

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. 

14.    NO RECOURSE AGAINST OTHERS. No
director, officer, employee, incorporator or stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or any Guarantor under the Notes, the Indenture, the Note Guarantees, or for any claim
based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release 

  
 A - 4













 EXHIBIT A 

are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws. 

15.    AUTHENTICATION. This Note will not be valid until authenticated by the manual
