form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. 
 The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a
part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note
conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 
 (b) Global

definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent
such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of
outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

 Section 2.02 Execution and
Authentication. 
 At least one Officer must sign the Notes for the Company by manual or facsimile signature. 

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be
valid. 
 A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence
that the Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a written order of the Company signed by an
Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not
exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

with Holders or an Affiliate of the Company. 
 Section 2.03 Registrar and Paying Agent. 

The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar

 The Company initially appoints

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

Section 2.05 Holder Lists. 

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
all Holders. If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of Holders.

otherwise agreed by the Company and a holder of a beneficial interest in a Global Note. 
 Upon the occurrence of any of the preceding

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

(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:

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;

 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. 

  
 37 








 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). 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 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. 

  
 38 








 Section 2.14 No Reissuance of Notes.

Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth: 
 (1) the clause
of this Indenture pursuant to which the redemption shall occur; 
 (2) the redemption date; 

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

(4) the redemption price. 
 If
the redemption price is not known at the time such notice is to be given, the actual redemption price, calculated as described in the terms of the Notes to be redeemed, shall be set forth in an Officers’ Certificate of the Company delivered to
the Trustee no later than two Business Days prior to the redemption date. 
 Section 3.02 Selection of Notes to Be Redeemed or
Purchased. 
 If less than all the Notes are to be redeemed, the Trustee shall select the Notes to be redeemed subject to DTC’s
Applicable Procedures for Global Notes in any manner that the Trustee deems fair and appropriate, including by lot, pro rata or other method. The Trustee shall make the selection at least 30 days but no more than 60 days before the redemption date
from Notes outstanding not previously called for redemption. The Trustee will select the Notes to be redeemed in principal amounts of $2,000 or integral multiples of $1,000 in excess thereof. If less than all outstanding Notes are to be redeemed,
any selection of Notes to be redeemed shall be subject to the Applicable Procedures in the case of any Global Note. The Trustee will make the selection at least 30 days but no more than 60 days before the redemption date from outstanding Notes not
previously called for redemption. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

Section 3.03 Notice of Redemption. 

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to each
Holder whose Notes are to be redeemed, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture
pursuant to Article 8 hereof. 
 The notice shall identify the Notes to be redeemed and shall state: 

(a) the redemption date; 

  
 39 








 (b) the redemption price; 

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

(d) if any Notes are being redeemed in part, the portion of the principal amount of the Notes to be redeemed and that, after the redemption
date and upon surrender of the Notes, new Notes in principal amount equal to the unredeemed portion of the original Notes shall be issued in the name of the Holder thereof upon cancellation of the original Notes; 

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

(f) that interest on the Notes called for redemption ceases to accrue on and after the redemption date unless the Company defaults in the
deposit of the redemption price; 
 (g) the CUSIP number, if any; and 

(h) any other information as may be required by the terms of the Notes being redeemed. 

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense;
provided, however, that the Company has delivered to the Trustee, at least 10 days (unless a shorter time shall be acceptable to the Trustee) prior to the notice date, an Officers’ Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice.  
 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. 
 Section 3.04 Effect of
Notice of Redemption. 
 Once notice of redemption is mailed as provided in Section 3.03, Notes called for redemption become due and
payable on the redemption date and at the redemption price. Upon surrender to the Paying Agent, the Notes shall be paid at the redemption price plus accrued interest to the redemption date. If the redemption notice is given and funds deposited as
required by Section 3.05, then interest will cease to accrue on and after the redemption date on the Notes or portions of such Notes called for redemption. 

Section 3.05 Deposit of Redemption or Purchase Price. 

On or before 11:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Paying Agent money sufficient to pay
the redemption price of and accrued interest, if any, on all Notes to be redeemed on that date. In the event that any redemption date is not a Business Day, the Company will pay the redemption price on the next Business Day without any interest or
other payment due to the delay.

 Section 3.06 Notes Redeemed or Purchased in Part.

principal amount to the unredeemed portion of the Note surrendered. 
 Section 3.07 Optional Redemption

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 Company 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

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 Company or any of its Restricted Subsidiaries in connection with such disposition; 

(23) Indebtedness of the Company 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 Company 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 Guarantor 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 Company) for senior subordinated “high yield” debt securities or (B) unsecured, pari passu with all Notes and Guarantor Obligations and convertible
into common stock of the Company; 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

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 Company
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. 
 (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 of operating leases or any other instrument or transaction as Indebtedness due
to a change in accounting principles or in GAAP or due to a modification of such operating leases; 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 Company 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 $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 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: 

  
 52 








 (1) accept for payment all Notes or portions of Notes properly tendered pursuant
to the Change of Control Offer; 
 (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 Officers’ 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 30 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. 

(a) The Board of Directors may designate any Restricted Subsidiary of the Company (other than a Guarantor) to be an Unrestricted Subsidiary if
that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary
designated as 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 Company 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 Company giving effect to such designation and an Officers’ Certificate
certifying that such designation complied with the preceding conditions. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation
shall be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation 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, none of US Airways Group, US Airways or American may be designated as an Unrestricted
Subsidiary. 
 ARTICLE 5 

SUCCESSORS 
 Section 5.01
Merger and Sales of Assets. 
 (a) The Company and any Guarantor may consolidate with or merge into, or convey, transfer or lease all
or substantially all of the Company’s or such Guarantor’s properties and assets to, any Person (including in connection with an Airlines Merger); provided that: 

(1) the resulting, surviving or transferee Person is a Person organized and existing under the laws of the United States of
America, any state thereof or the District of Columbia, and expressly assumes by a supplemental indenture, all of the Company’s obligations under the Notes and this Indenture (in the case of the Company) or the obligations under the applicable
Note Guarantee (in the case of a Guarantor); and 
 (2) except in connection with any Airlines Merger or a merger of US
Airways Group with the Company or a Guarantor, 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 Officers’ Certificate and an Opinion of Counsel stating that such
consolidation, merger or transfer and such supplemental indenture (if any) complies with this Indenture. 
 (b) Any such successor shall
succeed to and be substituted for, and may exercise every right and power of, the Company or such Guarantor, 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. 

  
 54 








 (c) For the avoidance of doubt, this Section 5.01 shall not restrict mergers, conveyances,
transfers or leases by a Restricted Subsidiary of the Company that is not the Company or a Guarantor. 
 Section 5.02 Successor
Corporation Substituted. 
 Upon any consolidation or merger, or any sale, lease, conveyance or other disposition of all or
substantially all of the assets of the Company in accordance with Section 5.01, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, lease, conveyance or other disposition is
made shall succeed to, and be substituted for, 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.  

ARTICLE 6 
 DEFAULTS AND REMEDIES

 Section 6.01 Events of Default. 

An “Event of Default” occurs with respect to the Notes if any of the following occurs:  

(1) default in any payment of the principal amount or premium, if any, on any of the Notes when such amount becomes due and
payable at Stated Maturity, upon acceleration, redemption or otherwise; 
 (2) failure to pay interest on the Notes when such
interest becomes due and payable and such failure continues for a period of 30 days; 
 (3) failure to comply with any of the
covenants or agreements applicable to the Notes (other than those referred to in (1) or (2) above) and such failure continues for 60 days after the notice specified below; 

(4) except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid
or ceases for any reason to be in full force and effect, or a Guarantor denies or disaffirms in writing its obligations under its Note Guarantee; or 

(5) the Company or any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of
Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: 

(A) commences a voluntary case, 

(B) consents to the entry of an order for relief against it in an involuntary case, 

(C) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, 

(D) makes a general assignment for the benefit of its creditors, or 

  
 55 








 (E) consents to or acquiesces in the institution of a bankruptcy or an insolvency
proceeding against it; 
 (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against the Company or any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group
of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case, 
 (B)
appoints a Bankruptcy Custodian of the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or
substantially all of its (or their) property, or 
 (C) orders the liquidation of the Company, any Restricted Subsidiary of
the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, and the order or decree remains unstayed and in effect for 60 days. 

A Default under clause (3) 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 acceleration, have been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereon. 

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

The Company covenants that if: 

  
 56 








 (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 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 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. 

  
 57 








 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 

  
 58 








 (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. 

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 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:

(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

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,
including the Stated Maturity expressed in the Notes (or, in the case of redemption, on the redemption date). 
 ARTICLE 7 

TRUSTEE 
 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 vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

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

(1) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others. 

(2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon Officers’ 

  
 60 








 
Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements of this Indenture; however, in the case of any such Officers’ Certificates or Opinions of
Counsel which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officers’ Certificates and Opinions of Counsel to determine whether or not they conform to the form requirements of
this Indenture. 
 (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or
its own willful misconduct, except that: 
 (1) this paragraph does not limit the effect of paragraph (b) of this
Section 7.01; 
 (2) the Trustee will not be liable for any error of judgment made in good faith by a Responsible
Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) The Trustee shall
not be liable with respect to any action taken, suffered or omitted to be taken by it with respect to the Notes in good faith in accordance with the direction of the Holders of a majority in principal amount of the outstanding Notes relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Notes in accordance with Section 6.12.

paragraphs (a), (b), and (c) of this Section 7.01.

held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 (g) No provision of this
Indenture shall require the Trustee to risk its own funds or otherwise incur any financial liability in the performance of any of its duties, or in the exercise of any of its rights or powers, if adequate indemnity against such risk is not assured
to the Trustee in its satisfaction. 
 (h) The Paying Agent, the Registrar and any authenticating agent shall be entitled to the protections
and immunities as are set forth in paragraphs (e), (f) and (g) of this Section 7.01 and in Section 7.02, each with respect to the Trustee. 

Section 7.02 Rights of Trustee. 

(a) The Trustee may rely on and shall be protected in acting or refraining from acting upon any document (whether in its original or facsimile
form) believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 

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

  
 61 








 (c) The Trustee may act through agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care. No Depositary shall be deemed an agent of the Trustee and the Trustee shall not be responsible for any act or omission by any Depositary. 

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within
its rights or powers, provided that the Trustee’s conduct does not constitute willful misconduct or negligence. 
 (e) The
Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder without willful misconduct or
negligence, and in reliance thereon. 
 (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by
this Indenture at the request or direction of any of the Holders of Notes unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction. 
 (g) The Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit.

Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and
such notice 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. 
 Section 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or an
Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee is also subject to Section 7.09. 

Section 7.04 Trustee’s Disclaimer. 

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the
Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement in the Notes other than its authentication. 

  
 62 








 Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing with respect to the Notes and if it is known to a Responsible Officer of the Trustee,
the Trustee shall mail to each Holder notice of the Default or Event of Default within 90 days after it occurs or, if later, after a Responsible Officer of the Trustee has knowledge of 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 as its corporate trust committee or a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interests of Holders of the Notes. 
 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 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 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 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 expenses of administration under any Bankruptcy Law. 

The provisions of this Section shall survive the termination of this Indenture. 

Section 7.07 Replacement of Trustee. 

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. The Company may remove the
Trustee with respect to the Notes if: 
 (1) the Trustee fails to comply with Section 7.09; 

  
 63 








 (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, 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. 

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.

contemplated by Section 8.03 or 8.04. 
 (b) The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against Government Securities deposited pursuant to Section 8.03 or 8.04 or the interest and principal received in respect of such obligations other than any payable by or on behalf of Holders. 

  
 65

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.

4.08, 4.10, 4.11 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

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

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

ARTICLE 9 
 AMENDMENT, SUPPLEMENT
AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. 

The Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder: 

(a) to evidence the succession of another Person to the Company or any Guarantor pursuant to Section 5.01 and the assumption by such

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; 

  
 68 








 (d) to cure any ambiguity or correct or supplement any provision contained in this Indenture, in
any supplemental indenture, Officers’ 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 security for the Notes; 

(i) to provide additional guarantees for the Notes; 

(j) to make any change that does not adversely affect the rights of any Holder of the Notes; or 

(k) 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. 

Section 9.02 With Consent of Holders of Notes. 

The Company and the Trustee may enter into a supplemental indenture 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 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; 

  
 69 








 (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 conveyance, transfer or lease of assets pursuant to Section 5.01 of this Indenture, release any Guarantor from its obligations under its Note Guarantee or make any change in any Note Guarantee that would
adversely affect such Holder; 
 (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. 

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

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 11.02. The Trustee shall sign all supplemental indentures upon delivery of such an Officers’ Certificate or Opinion of Counsel or both, except that the Trustee need not sign any supplemental indenture that adversely affects its
rights. 
 ARTICLE 10. 
 NOTE
GUARANTEES 
 Section 10.01 Note Guarantees. 

(a) Subject to the provisions of this Section 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. 
 (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. 

  
 71 








 (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. 
 (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). 

  
 72 








 (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. 

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 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.

1. INTEREST. American Airlines Group Inc., a Delaware corporation (the
“Company”), promises to pay or cause to be paid interest on the principal amount of this Note at 4.625% per annum from             ,
            until maturity. The Company will pay interest, if any, semi-annually in arrears on March 1 and September 1 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance;
provided that 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 is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. 

Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

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 February 15 or August 15 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. 

3. PAYING AGENT AND REGISTRAR. Initially,

Subsidiaries may act as Paying Agent or Registrar. 
 4. INDENTURE. The Company issued
the Notes under an Indenture dated as of March 5, 2015 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms,
and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are
unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. 

5. OPTIONAL REDEMPTION; CHANGE OF CONTROL
REPURCHASE.

any time or in part from time to time, at a redemption price equal to the greater of (1) 100% of the principal 

  
 A-2 









 EXHIBIT A 
  

 
amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes (excluding accrued and unpaid interest 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 interest payment
date). 
 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 $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 30 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 30 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 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 

  
 A-3 









 EXHIBIT A 
  

 
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. Subject
to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if
any, voting as a single class, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal
amount of the then outstanding Notes including Additional Notes, if any, voting as a single class. Without the consent of any Holder of the Notes, the Indenture, the Notes or the Note Guarantees may be amended or supplemented to evidence the
succession of another Person to the Company or any Guarantor pursuant to Section 5.01 of the Indenture and the assumption by such successor of the Company’s or such Guarantor’s covenants, agreements and obligations under the Indenture
and with respect to the Notes; to surrender any right or power conferred upon the Company or the Guarantors; 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; to cure any ambiguity or correct or supplement any provision contained in the Indenture, in any supplemental indenture, Officers’ Certificate or in the Notes that may be defective or inconsistent with
any other provision contained herein or therein; 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 the Indenture as shall not
adversely affect the interests of any Holder of the Notes; to modify or amend the Indenture in such a manner as to permit the qualification of the Indenture or any supplemental indenture under the TIA as then in effect; to add to or change any
provisions of the 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; to provide security for the Notes; to provide additional guarantees for the Notes; to make any change that does not adversely affect the rights of any Holder of the Notes; or 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 the Indenture as shall be necessary to provide for or facilitate the administration of the Indenture by more than one trustee. 

11. DEFAULTS AND REMEDIES. If an Event of Default occurs and
is continuing (other than an Event of Default referred to Section 6.01(5) or 6.01(6) of the Indenture), 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 the Holders), and upon any such declaration such principal amount and
accrued and 

  
 A-4 









 EXHIBIT A 
  

 
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) of the Indenture 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. Holders of Notes may not enforce the
Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to exercise any of its rights or powers under the Indenture at the direction of Holders unless the Holders have offered security or indemnity satisfactory to
the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in principal amount of
the Notes then outstanding to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with respect to the Notes. The Trustee may withhold
from Holders of Notes notice of any continuing Default with respect to the Notes (except a Default in payment of principal, or premium if any, or accrued and unpaid interest with respect to the Notes) in accordance with the provisions of the
Indenture if a committee of the Trustee’s trust officers in good faith determines that withholding notice is in the interest of the Holders. 

12. 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. 

13. 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 the Guarantors 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 are part of the consideration for issuance of the Notes. The waiver may not
be effective to waive liabilities under the federal securities laws. 
 14.
AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 

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

16. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such
numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 

17. GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS
NOTE AND THE NOTE GUARANTEES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

 we
