(2) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or
another Restricted Subsidiary; or 
 (3) Capital Stock constituting a minority interest in any Person that at such time is a Restricted
Subsidiary; 
 provided, however, that any such Restricted Subsidiary described in clause (2) or (3) above is primarily engaged in the

 (1) that all Parity Lien
Obligations will be and are secured equally and ratably by all Parity Liens at any time granted by the Company or any Guarantor to secure any Obligations in respect of such Series of Parity Lien Debt, whether or not upon property otherwise
constituting collateral for such Series of Parity Lien Debt, and that all such Parity Liens will be enforceable by the Collateral Agent for the benefit of all holders of Parity Lien Obligations equally and ratably; and 

(2) appointing the Collateral Agent and consenting to the performance by the Collateral Agent of, and consenting to and

Pledged Aircraft and Aircraft-Related Collateral related to such Pledged Aircraft; and (D) any Airbus 

  
 6 







 
H225/Eurocopter EC225 helicopter for which a “desktop appraisal” is not generally available regardless of configuration, the “fair market value” for such Pledged Aircraft and
Aircraft-Related Collateral related to such Pledged Aircraft will be the lesser of the net book value thereof or $5.8 million.

2019. 
 “Aircraft-Related Collateral” means (i) all Engines, rotor blades, rotor blade components, auxiliary power

Note will be dated the date of its authentication. The Notes shall be in 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 Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend
thereon and the “Schedule of Increases or Decreases in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend


  
 42 







 
thereon and without the “Schedule of Increases or Decreases in the Global Note” attached thereto). Each Global Note will represent such aggregate principal amount 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, repurchases, transfers of interests 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 Notes Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 3.06 hereof. Notes initially
offered and sold to QIBs in the United States in reliance on Rule 144A shall be issued in the form of one or more QIB Global Notes, duly executed by the Company and the Guarantors and authenticated by the Trustee as hereinafter provided. Notes
offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the
Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and the Guarantors and authenticated by the
Trustee as hereinafter provided. The procedures of Euroclear and Clearstream will be applicable to transfers of beneficial interests in the Regulation S Global Note that are held by Participants through Euroclear or Clearstream. 

SECTION 3.02 Execution and Authentication. 

At least one Officer must sign the Notes for the Company by manual, facsimile or electronic (including “.pdf”) 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 authenticate and deliver: (i) Initial Notes for original
issue in an aggregate principal amount of $350.0 million and (ii) if and when issued, Additional Notes, in each case upon receipt of a written order of the Company signed by two Officers of the Company (an “Authentication Order”)
and, in the case of Additional Notes, upon receipt of an Officers’ Certificate stating such Additional Notes are permitted to be incurred under Section 5.09 and are permitted to be secured as Parity Lien Debt under Section 5.12. Such
order shall specify the amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated. 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 3.07 hereof.

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 without notice to any Holder. The Company will notify the Trustee
in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Restricted Subsidiaries
(other than a Foreign Subsidiary) may act as Paying Agent. 
 The Company initially appoints The Depository Trust Company (“DTC”)
to act as Depositary with respect to the Global Notes. 
 The Company initially appoints the Trustee in New York, New York to act as the
Registrar and Paying Agent and to act as Notes Custodian with respect to the Global Notes. 
 SECTION 3.04 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, premium, if any, or interest 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 3.05 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 and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the
Company will furnish to the Trustee at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the
names and addresses of the Holders, and the Company shall otherwise comply with TIA § 312(a).

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Company for Definitive Notes if: 
 (1) the Company delivers to the Trustee notice from the Depositary that it is
unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice
from the Depositary; 
 (2) the Company in its sole discretion determines that the Global Notes (in whole but not in part)
should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or 

(3) there has occurred and is continuing a Default or Event of Default and the Depository so requests. 

Upon the occurrence of either of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall
instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.07 and 3.10 hereof. A Global Note may not be exchanged for another Note other than as provided in this Section 3.06(a),
however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 3.06(b) or (c) hereof. 

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global
Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set
forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other
following subparagraphs, as applicable: 
 (1) Transfer of Beneficial Interests in the Same Global Note. Beneficial
interests in any Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Note in accordance with the Applicable Procedures and, if applicable, the transfer restrictions set forth in
the Private Placement Legend. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 3.06(b)(1). 

(2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and
exchanges of beneficial interests that are not subject to Section 3.06(b)(1) above, the transferor of such beneficial interest must, as applicable, deliver to the Registrar either: 

  
 45 







 (i) both: 

(1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable
Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

(2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account
to be credited with such increase; or 
 (ii) both: 

(1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable
Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

(2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such
Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above. 
 Upon satisfaction of all of the requirements for
transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act or the Applicable Procedures, the Trustee shall adjust the principal amount of the relevant
Global Note(s) pursuant to Section 3.06(g) hereof. 
 (3) Transfer of Beneficial Interests to Another Restricted
Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of
Section 3.06(b)(2) above and the Registrar receives the following, in each case as applicable: 
 (i) If the transferee
will take delivery in the form of a beneficial interest in the QIB Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; and

(1) Private Placement Legend. Except as permitted by this Section 3.06, each Global Note and each Definitive Note
(and all Notes issued in exchange therefor or substitution thereof) shall bear the legend in substantially the following form: 
 “THE
SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT
BE OFFERED, SOLD OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: REPRESENTS THAT IT, AND ANY ACCOUNT FOR WHICH IT IS ACTING, (A) IS A
“QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) OR (B) IS NOT A “U.S. PERSON” (WITHIN THE MEANING OF RULE 902 OF REGULATION S UNDER THE SECURITIES ACT), AND THAT IT EXERCISES SOLE
INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND (2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR 

  
 49 







 
ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE RESALE RESTRICTION TERMINATION DATE (AS DEFINED IN THE NEXT PARAGRAPH), EXCEPT: (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR (B) PURSUANT
TO A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR (C) TO A PERSON REASONABLY BELIEVED TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR (D) IN AN OFFSHORE
TRANSACTION IN COMPLIANCE WITH RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT; OR (E) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT. THE RESALE RESTRICTION TERMINATION DATE WILL BE THE DATE (1) THAT IS AT LEAST ONE YEAR AFTER THE ORIGINAL ISSUE DATE HEREOF AND (2) ON WHICH THE COMPANY INSTRUCTS THE TRUSTEE THAT THIS LEGEND SHALL BE
DEEMED REMOVED FROM THIS SECURITY, IN ACCORDANCE WITH THE PROCEDURES DESCRIBED IN THE INDENTURE RELATED TO THIS SECURITY. PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH (E) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO
REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO
REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 BY ITS
ACQUISITION AND HOLDING OF THIS SECURITY, THE HOLDER THEREOF WILL BE DEEMED TO HAVE REPRESENTED, WARRANTED AND AGREED THAT EITHER (I) NO PORTION OF THE ASSETS USED BY SUCH HOLDER TO ACQUIRE OR HOLD THIS SECURITY (OR ANY INTEREST IN THIS
SECURITY) CONSTITUTES THE ASSETS OF AN EMPLOYEE BENEFIT PLAN SUBJECT TO THE FIDUCIARY RESPONSIBILITY REQUIREMENTS OF TITLE I OF ERISA, OF A PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT SUBJECT TO SECTION 4975 OF THE U.S. INTERNAL REVENUE
CODE OF 1986, AS AMENDED (THE “CODE”), A GOVERNMENTAL, CHURCH, NON-U.S., OR OTHER PLAN WHICH IS SUBJECT TO ANY FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR
REGULATIONS THAT ARE SUBSTANTIALLY SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE (“SIMILAR LAWS”), OR AN ENTITY WHOSE UNDERLYING ASSETS ARE CONSIDERED TO INCLUDE “PLAN ASSETS” BY REASON OF SUCH PLAN’S, ACCOUNT’S OR
OTHER ARRANGEMENT’S INVESTMENT IN THE ENTITY, OR (II) THE ACQUISITION, HOLDING AND DISPOSITION OF THIS SECURITY WILL NOT CONSTITUTE A NON-

  
 50 







 
EXEMPT PROHIBITED TRANSACTION UNDER ERISA OR SECTION 4975 OF THE CODE OR, IN THE CASE OF A PLAN THAT IS NOT SUBJECT TO ERISA OR SECTION 4975 OF THE CODE, A SIMILAR VIOLATION UNDER ANY APPLICABLE
SIMILAR LAWS.” 
 (2) Global Note Legend. Each Global Note will bear a legend in substantially the following
form: 
 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE
BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 3.06 OF THE INDENTURE, (2) THIS GLOBAL
NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 3.06 OF THE INDENTURE, (3) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 3.11 OF THE INDENTURE AND (4) THIS GLOBAL NOTE MAY BE
TRANSFERRED TO A SUCCESSOR DEPOSITARY IN ACCORDANCE WITH THE INDENTURE. 
 UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN
DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO
A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) (“DTC”), TO THE COMPANY OR ITS
AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO
CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF,
CEDE & CO., HAS AN INTEREST HEREIN.” 
 (g) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and
canceled by the Trustee in accordance 

  
 51 







 
with Section 3.11 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 Registrar or by
the Depositary at the direction of the Registrar to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note,
such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Registrar or by the Depositary at the direction of the Trustee to reflect such increase. 

(h) General Provisions Relating to Transfers and Exchanges. 

(1) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes
and Definitive Notes upon receipt of an Authentication Order in accordance with Section 3.02 hereof or at the Registrar’s request. 

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note
for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchange or transfer pursuant to Sections 3.10, 4.06, 4.10, 5.15 and 10.05 hereof). 
 (3)
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. 
 (4) Neither
the Registrar nor the Company will be required: 
 (i) to issue, to register the transfer of or to exchange any Notes during
a period beginning at the opening of business 15 days prior to the mailing of a notice of redemption; 
 (ii) to register the
transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 

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

 (5) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may
deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes,


  
 52 







 
and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. Members of, or participants in, the Depositary (“Agent Members”) shall have no
rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee or the Custodian as its custodian, or under such Global Note, and the Depositary may be treated by the Company, any Guarantor, the
Trustee or the Custodian and any agent of the Company, any Guarantor, the Trustee or the Custodian as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered Holder of a Global Note
may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder of Notes is entitled to take under the Indenture or the Notes and
(ii) nothing herein shall prevent the Company, any Guarantor, the Trustee or the Custodian, or any agent of the Company, any Guarantor, the Trustee or the Custodian, from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. 

(6) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 3.02
hereof. 
 (7) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to
this Section 3.06 to effect a registration of transfer or exchange may be submitted by facsimile. 
 SECTION 3.07 Replacement Notes. 

If any mutilated Note is surrendered to the Registrar or the Company and the Registrar 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 (accompanied by a notation of any Guarantees duly endorsed) if the Registrar’s
requirements are met. If required by the Registrar or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Registrar, 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 3.08 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 3.08 as not outstanding. Except as set forth in Section 3.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 

  
 53 







 If a Note is replaced pursuant to Section 3.07 hereof, it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code). 

If the principal amount of any Note is considered paid under Section 5.01 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 such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 

SECTION 3.09 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 a Responsible Officer knows are so owned will be so disregarded. 
 SECTION 3.10 Temporary Notes. 

Until definitive 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 3.11 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 dispose of the canceled Notes in accordance with its normal procedures (subject to the record retention requirement of the Exchange
Act). Certification of the disposition of all canceled Notes will be delivered to the Company upon written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.


  
 54 







 SECTION 3.12 Defaulted Interest. 

If the Company defaults in a payment of interest on the Notes, the Company shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest on the defaulted interest, in each case at the rate provided in the Notes and in Section 5.01. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15
days before any special record date selected by the Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20 days’ prior written notice from the Company setting forth such special record date and the
interest amount to be paid) shall mail to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

SECTION 3.13 CUSIP Numbers. 
 The
Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers and corresponding “ISINs” in notices of redemption as
a convenience to the Holders thereof; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption
and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. 

SECTION 3.14 Issuance of Additional Notes. 

After the Initial Issuance Date, the Company shall be entitled, subject to its compliance with Section 5.09 and Section 5.12, to
issue Additional Notes under the Indenture, which shall have identical terms as the Initial Notes issued on the Initial Issuance Date, other than with respect to the date of issuance. With respect to any Additional Notes, the Company shall set forth
in a Board Resolution and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information: 

(a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to the Indenture; 

(b) the issue date and the CUSIP number of such Additional Notes; 

(c) the date from which interest shall accrue on such Additional Notes; and 

(d) the other statements required by Section 3.02. 

  
 55 







 ARTICLE IV 

REDEMPTION AND PURCHASE 
 SECTION 4.01
Notice to the Trustee. 
 If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 4.08
hereof, it shall notify the Trustee of the redemption date and the principal amount of Notes to be redeemed. The Company shall so notify the Trustee at least 20 days before the redemption date (unless a shorter notice shall be satisfactory to the
Trustee) by delivering to the Trustee an Officers’ Certificate stating that such redemption will comply with the provisions of the Indenture and of the Notes. Any such notice may be canceled at any time prior to the mailing of such notice of
such redemption to any Holder and shall thereupon be void and of no effect. 
 SECTION 4.02 Selection of Notes to Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, selection of Notes for redemption will be made by the Trustee on a pro
rata basis, by lot or by such method as the Trustee shall deem fair and appropriate or require unless otherwise required by law or applicable stock exchange or depositary requirements. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal amount to be redeemed. A new Note in principal amount equal to the unredeemed portion will be issued in the name of the Holder upon cancellation of the original Note.
Notes called for redemption become due on the date fixed for redemption, unless a condition precedent to redemption set forth in the notice of redemption as described in Section 4.03 has not been satisfied. 

The Trustee shall promptly notify the Company and the Registrar in writing of the Notes selected for redemption and, in the case of any Notes
selected for partial redemption, the principal amount thereof to be redeemed. No Notes of $2,000 or less in principal amount can be redeemed or purchased in part. Notes and portions of Notes selected will be in amounts of $2,000 or whole 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. 

For purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Notes shall relate, in the
case of any of the Notes redeemed or to be redeemed only in part, to the portion of the principal amount thereof which has been or is to be redeemed. 

SECTION 4.03 Notice of Redemption. 

Notices of redemption shall be mailed by first class mail (or in the case of Global Notes, delivered electronically in accordance with the
procedures of the depositary) at least 15 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address, except that notices of the Special Mandatory Redemption shall be mailed or delivered at
least five Business Days before July 14, 2022. Notices of any optional redemption may, at the Company’s option, be subject to one or more conditions precedent, including, without limitation, consummation of a Qualified Equity Offering or a
Change of Control. 

  
 56 







 All notices of redemption shall identify the Notes to be redeemed and shall state: 

(1) the redemption date; 

(2) the redemption price (or the method by which it will be calculated); 

(3) that, unless the Company and the Guarantors default in making the redemption payment, interest on Notes called for
redemption ceases to accrue on and after the redemption date, and the only remaining right of the Holders of such Notes is to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed; 

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

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

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

(7) the CUSIP number, if any, relating to the Notes and that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Notes; and 
 (8) any conditions for such redemption. 

Notice of redemption of Notes to be redeemed at the election of the Company shall be given by the Company or, at the Company’s written
request, by the Trustee in the name and at the expense of the Company. 
 SECTION 4.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed in accordance with Section 4.03 hereof, Notes called for redemption become irrevocably due and
payable on the redemption date and at the redemption price, subject to satisfaction of any conditions thereto. Upon surrender to the Paying Agent, such Notes called for redemption shall be paid at the redemption price, but interest installments due
on or prior to such redemption date will be payable on the relevant interest payment dates to the Holders of record of such Notes at the close of business on the relevant record dates. 

  
 57 







 SECTION 4.05 Deposit of Redemption Price. 

On or prior to 11:00 a.m., New York City time, on any redemption date, the Company or a Guarantor will deposit with the Trustee or with the
Paying Agent money sufficient to pay the redemption of and accrued interest, if any, on all Notes to be redeemed or on that date. The Trustee or the Paying Agent will promptly return to the Company or such Guarantor any money deposited with the
Trustee or the Paying Agent by the Company or such Guarantor in excess of the amounts necessary to pay the redemption price of and accrued interest, if any, on all Notes to be redeemed. 

If the Company or a Guarantor complies with the provisions of the preceding paragraph, on and after the redemption date, interest will cease
to accrue on the Notes or the portions of Notes called for redemption, whether or not such Notes are presented for payment, and the Holders of such Notes shall have no further rights with respect to such Notes except for the right to receive the
redemption price of, and accrued interest, if any, on such Notes upon surrender of such Notes. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall
be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption is not so paid upon surrender for redemption because of the failure of the Company or a Guarantor to comply
with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in
the Notes and in Section 5.01 hereof. 
 SECTION 4.06 Notes Redeemed in Part. 

Upon surrender of a Note that is redeemed in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will
authenticate for the Holder of such Note at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 

SECTION 4.07 Purchase of Notes. 

The Company, any Guarantor or any Affiliate of the Company or any Guarantor may, subject to applicable law, at any time purchase or otherwise
acquire Notes in the open market or by private agreement. Any such acquisition shall not operate as or be deemed for any purpose to be a redemption of the indebtedness represented by such Notes. Any Notes purchased or acquired by the Company or a
Guarantor may be delivered to the Trustee and, upon such delivery, the indebtedness represented thereby shall be deemed to be satisfied. Section 3.11 shall apply to all Notes so delivered. 

SECTION 4.08 Optional Redemption. 

(a) On and after March 1, 2020, the Notes will be subject to redemption on one or more occasions at the option of the Company, in whole or
in part at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, to the applicable redemption date (subject to the rights of Holders of the Notes on the relevant record date
to receive interest due on the relevant interest payment date), if redeemed during the 12-month period beginning on March 1 of the years indicated below:

(subject to the rights of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date), in an amount not to exceed the net cash proceeds of one or more Qualified Equity Offerings, provided that:

 (1) at least 65% of the aggregate principal amount of Notes (including any Additional Notes) issued remains outstanding
immediately after the occurrence of each such redemption; and 
 (2) each such redemption occurs within 180 days of the date
of the closing of each such Qualified Equity Offering.

occasions redeem all or part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date (subject to the rights of
Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date). 
 (b) Any redemption
pursuant to this Section 4.08 shall be made pursuant to the provisions of Sections 4.01 through 4.06 hereof. 
 SECTION 4.09 Special Mandatory
Redemption. 
 (a) Except as set forth below or under Section 5.10 and Section 5.15, the Company shall not be required to make
mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders. 
 (b) If as

on July 14, 2022, the Company will redeem all Notes then outstanding, at a redemption price in cash equal to 100% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to July 14, 2022 (a “Special
Mandatory Redemption”). 

  
 59 







 (c) If as of June 30, 2022, there remains outstanding no more than $125.0 million
principal amount of the aggregate of (i) the 2022 Notes, plus (ii) the principal amount of any Indebtedness incurred to refinance 2022 Notes that matures or is required to be repaid prior to June 1, 2023, plus, (iii) in either

(d) The Company will give notice of any Special Mandatory Redemption as provided in Section 4.03. The provisions of Section 4.04 and
4.05 will also apply to any Special Mandatory Redemption. 
 SECTION 4.10 Offer to Purchase by Application of Excess Proceeds. 

In the event that, pursuant to Section 5.10 hereof, the Company is required to commence an Asset Sale Offer to all Holders to purchase
Notes and, to the extent other Indebtedness as specified therein, it will follow the procedures specified below. 
 The Asset Sale Offer
will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than
five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and other Indebtedness as specified in
Section 5.10(e) or, if less than the Offer Amount has been tendered, all Notes and such other Indebtedness validly tendered and not withdrawn in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same
manner as interest payments are made. 
 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice
to each of the Holders (or in the case of Global Notes, electronic notice in accordance with the procedures of the depositary), with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to
tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which will govern the terms of the Asset Sale Offer, will state: 

(1) that the Asset Sale Offer is being made pursuant to this Section 4.10 and Section 5.10 hereof and the length of
time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the purchase price and the Purchase Date; 

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

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

  
 60 







 (5) that Holders electing to have Notes purchased pursuant to any Asset Sale
Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the
Company, or a Paying Agent at the address specified in the notice prior to the end of the Offer Period; 
 (6) that Holders
will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder,
the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

(7) that, if the aggregate principal amount of Notes surrendered by Holders thereof and other Indebtedness as contemplated by
Section 5.10(e) surrendered by Holders or lenders, collectively, exceeds the Offer Amount, the Trustee shall select the Notes and such other Indebtedness to be purchased on a pro rata basis on the basis of the aggregate principal amount
of tendered Notes and such other Indebtedness (except that any Notes represented by a Note in global form will be selected by such method as the Depositary or its nominee or successor may require or, where the nominee or successor is the Trustee, a
method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes
in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and 
 (8) that Holders
whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal
amount or an integral multiple of $1,000 in excess thereof. 
 On or before the Purchase Date, the Company will, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the principal amount of Notes or portions thereof required to be purchased pursuant to this Section 4.10 (or, if less than the Offer Amount has been tendered, all Notes
tendered), and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the
terms of this Section 4.10. The Company, a Guarantor, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than the Purchase Date) mail or deliver to each tendering Holder an amount equal to the
purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause
to be transferred by book-entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The
Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

 ARTICLE V 

COVENANTS 
 SECTION 5.01 Payment of
Notes. 
 The Company shall pay the principal of, and premium, if any, and interest, if any, on the Notes on the dates and in the manner
provided in the Notes. Principal, premium, if any, and interest, if any, shall be considered paid on the date due if the Paying Agent (other than the Company, a Guarantor or other Restricted Subsidiary) holds as of 11:00 a.m. New York time on that
date money deposited by the Company or a Guarantor designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due. All payments made by the Company under or with respect to the Notes will be made free and clear
of and without withhold or reduction for, or on account of, any taxes, unless the withholding or deduction of such taxes is then required by law. 

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, at a rate
equal to the then applicable interest rate on the Notes to the extent lawful; and it shall 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. 
 SECTION 5.02 Maintenance of Office or
Agency. 
 The Company will maintain in the contiguous United States, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, the Registrar or the Paying Agent) where Notes may be surrendered for registration of transfer or for exchange, where Notes may be presented for payment and where notices and demands to or upon the Company or a Guarantor in
respect of the Notes and the Indenture may be served; provided, however that the Company may, at its option, pay interest on the Notes by check mailed to Holders of the Notes at their registered address as it appears in the
Registrar’s books. The Company will give prompt written notice to the Trustee and the Guarantors of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee and the Guarantors with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency as provided in this
Indenture for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

  
 62

regulations, taking into account any extension of time, deemed filing date or safe harbor contemplated or provided for by Rule 12b-25 under the Exchange Act:

 So long as the Company is required to file

EDGAR system and such information is publicly available. 
 (b) If the Company has designated any of its Subsidiaries as Unrestricted
Subsidiaries, and such Unrestricted Subsidiaries’ total assets (determined in accordance with GAAP) as of the end of the most recently completed fiscal year exceed an amount equal to 5% of the consolidated total assets of the Company and
its Restricted Subsidiaries, then the quarterly and annual financial information required by Section 5.03(a) shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial

year has been made under the supervision of the signing Officers with a view to determining whether the Company or such Guarantor, as the case may be, has kept, observed, performed and fulfilled its obligations under this Indenture, and further

have knowledge and what action the Company or such Guarantor, as the case may be, is taking or proposes to take with respect thereto). 
 (b)
The Company or any Guarantor shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer of the Company or such Guarantor, as the case may be, becoming aware of any Default or Event of Default under this
Indenture and the Note Documents, an Officers’ Certificate specifying such Default or Event of Default and what action the Company or such Guarantor, as the case may be, is taking or proposes to take with respect thereto. 

SECTION 5.05 Taxes. 
 The Company
shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such
payment is not adverse in any material respect to the Holders of the Notes. 
 SECTION 5.06 Waiver of Stay, Extension and Usury Laws. 

Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and each of the
Company and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any such payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or make any similar payment to the

 (A) no Default or Event of
Default shall have occurred and be continuing or would occur as a consequence thereof; 
 (B) the Company would, at the time
of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant
to Section 5.09(a); and 
 (C) such Restricted Payment, together with the aggregate amount of all other Restricted

determination), or from the substantially concurrent contribution of common equity capital to the Company, with a sale or contribution being deemed substantially concurrent if such Restricted Payment occurs not more than 120 days after such sale or
contribution; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment shall be excluded from clause (4)(C)(ii) of Section 5.07(a); 

(3) the defeasance, redemption, repurchase, retirement or other acquisition of Junior Debt with the net cash proceeds from an

 67 







 (5) so long as no Default or Event of Default shall have occurred and be
continuing, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company held by any current or former employee, officer or director of the Company or any of its Restricted Subsidiaries; provided
that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $3.0 million in any calendar year (with any portion of such $3.0 million amount that is unused in any calendar year to
be carried forward to successive calendar years and added to such amount) plus, to the extent not previously applied or included, (i) the net cash proceeds received by the Company or any of its Restricted Subsidiaries from sales of

limitation, stock options, restricted stock and phantom stock) in order to satisfy any tax withholding obligation with respect to such exercise or vesting; 

(7) any required purchase, redemption, defeasance or other acquisition or retirement of any Junior Debt in the event of a
Collateral Disposition, an Asset Sale or a Change of Control, but only if prior to or simultaneously with such purchase, redemption, defeasance or other acquisition or retirement, the Company has made the Asset Sale Offer or Change of Control Offer,
as applicable, as provided Section 5.10 or Section 5.15 as applicable, with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Asset Sale Offer or Change of
Control Offer, as applicable; 
 (8) cash payments in lieu of the issuance of fractional shares; 

(9) the payment of up to $100.0 million in the aggregate for the defeasance, redemption, repurchase, repayment or other

least $150.0 million; and 
 (10) other Restricted Payments in an aggregate amount not to exceed $75.0 million.


  
 68 







 For purposes of determining compliance with this Section 5.07, in the event that a
Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in clauses (1)-(10) of Section 5.07(b) or as a Permitted Investment, the Company will be permitted to divide or classify (or later
divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section. 

(c) The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a
Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time
of such designation. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the Fair Market Value of such Investments at the time of such designation. Such designation will only be permitted if such
Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 

The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s)
or securities proposed to be transferred or issued by the Company or any Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this covenant
will be determined, in the case of amounts under $40.0 million, by an Officer of the Company and, in the case of amounts greater than or equal to $40.0 million, by the Board of Directors of the Company, whose resolution with respect
thereto will be delivered to the Trustee. 
 SECTION 5.08 Limitation on Dividends and Other Payment Restrictions Affecting Subsidiaries. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 

(1) (i) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock
or (ii) pay any Indebtedness or other obligations owed to the Company or any of its Restricted Subsidiaries; 
 (2) make
loans or advances to the Company or any of its Restricted Subsidiaries; or 
 (3) transfer any of its properties or assets to
the Company or any of its Restricted Subsidiaries. 

  
 69 







 (b) The provisions of Section 5.09(a) will not prohibit encumbrances or restrictions

(5) customary non-assignment provisions in contracts and leases entered into in the
ordinary course of business and consistent with past practices;

 (7) agreements governing purchase money obligations, mortgage financings and Capital Lease
Obligations incurred in compliance with Section 5.09, in each case that impose encumbrances or restrictions of the nature described in clause (3) of Section 5.08(a) on the properties or assets financed thereby;

(15) the issuance of Preferred Stock by a Restricted Subsidiary of the Company or the payment of dividends thereon in
accordance with the terms thereof; provided that the terms of such Preferred Stock do not expressly restrict the ability of a Restricted Subsidiary of the Company to pay dividends or make any other distributions on its Equity Interests (other
than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such other Equity Interests); and 

(16) agreements governing Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined by the Company in its reasonable and good
faith judgment. 
 SECTION 5.09 Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur” or an “incurrence”) any Indebtedness, the Company will not, and will not permit any
Guarantor to, issue any Disqualified Stock and the Company will not permit any of its Restricted Subsidiaries that are not Guarantors to issue any shares of Preferred Stock; provided, however, that the Company and any Guarantor may
incur Indebtedness or issue Disqualified Stock, and any Restricted Subsidiaries of the Company that are not Guarantors may issue any shares of Preferred Stock, if the Consolidated Interest Coverage Ratio for the Company’s most recently ended
four full fiscal quarters for which internal financial statements are available immediately 

  
 71 







 
preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness, Disqualified Stock or Preferred Stock had been incurred or issued, as the case may be, at the beginning of such four-quarter period. 

(b) The provisions of Section 5.09(a) will not prohibit the following (“Permitted Debt”): 

(1) the incurrence by the Company and its Restricted Subsidiaries of Indebtedness under Credit Facilities in an aggregate
principal amount at any one time outstanding not to exceed the greater of (i) $750.0 million (or the equivalent thereof in any other currency or currency unit) and (ii) 30% of Consolidated Net Tangible Assets, determined as of the date of
each such incurrence; 
 (2) the incurrence by the Company and its Restricted Subsidiaries of Existing Indebtedness; 

(3) the incurrence by the Company and its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business and
not for speculation; 
 (4) the incurrence by the Company and its Restricted Subsidiaries of Parity Lien Debt, including the
Notes and the Subsidiary Guarantees issued on the Initial Issuance Date, in an aggregate principal amount outstanding at any one time not to exceed (together with any Parity Lien Debt outstanding pursuant to clause (8) of this definition to
refinance such Parity Lien Debt) the greater of (x) the sum of the principal amount of the Notes issued on the Initial Issuance Date plus $50.0 million and (y) an amount such that, on the date of incurrence thereof and after giving
pro forma effect thereto and the application of proceeds therefrom, the Aircraft Collateral Asset Value Ratio would have been equal to or greater than 2.0 to 1.0; 

(5) guarantees by the Company or any Restricted Subsidiary of Indebtedness of the Company or any Restricted Subsidiary incurred
in accordance with the provisions of the Indenture, provided that any such guarantee by a Restricted Subsidiary that is not a Guarantor is of Indebtedness that is permitted to be incurred by a Restricted Subsidiary that is not a Guarantor;

 (6) the incurrence of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries,
provided that any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company, or any sale or other transfer of any such
Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company, shall be deemed to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, provided,
however: 

  
 72 







 (i) if the Company is the obligor on such Indebtedness and a Guarantor is not the
obligee, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes; 

(ii) if a Guarantor is the obligor on such Indebtedness and the Company or a Guarantor is not the obligee, such Indebtedness is
expressly subordinated in right of payment to the Subsidiary Guarantee of such Guarantor, 
 (7) the incurrence by the
Company or any of its Restricted Subsidiaries of Indebtedness in respect of tenders, bids, statutory obligations, contracts, leases, workers compensation obligations, insurance obligations, performance, appeal and surety bonds issued for the account
of the Company or any Restricted Subsidiary and other obligations of like nature, in each case incurred in the ordinary course of business, including guarantees or obligations of the Company or any Restricted Subsidiary with respect to letters of
credit supporting such obligations (in each case other than for an obligation for money borrowed); 
 (8) the incurrence by
the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness that was permitted by the Indenture
to be incurred under clauses (2), (4), (9), (10) and this clause (8) of this Section 5.09(b); 
 (9) the incurrence
by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations with respect to assets other than Capital Stock or other Investments, in each case
incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property used in the business of the Company or such Restricted Subsidiary in an aggregate principal amount
at any one time outstanding not to exceed (together with any Indebtedness outstanding pursuant to clause (8) of this definition to refinance any Indebtedness incurred pursuant to this clause (9)) the greater of (i) $50.0 million and (ii)
3% of Consolidated Net Tangible Assets, determined as of the date of each such incurrence; 
 (10) Indebtedness of a
Restricted Subsidiary outstanding on the date on which such Restricted Subsidiary, or assets relating to such Indebtedness, were acquired by the Company or any of its Restricted Subsidiaries, or Indebtedness incurred by the Company or a Restricted
Subsidiary to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Restricted Subsidiary becomes a Restricted Subsidiary or is otherwise acquired by, or such assets
are acquired by, the Company or any of its Restricted Subsidiaries; provided, however, that at the time such Restricted Subsidiary is acquired by the Company or on the date of such asset acquisition, as applicable, the Consolidated
Interest Coverage Ratio for the Company’s most recent four quarters for which internal financial statements are available, after giving pro forma effect to the acquisition and the incurrence of any related Indebtedness, would be (i) at
least 2.0 to 1.0 or (ii) equal to or greater than the Consolidated Interest Coverage Ratio determined for such four quarter period without giving effect to such acquisition and incurrence of Indebtedness; 

  
 73 







 (11) Indebtedness arising from agreements of the Company or a Restricted
Subsidiary providing for indemnification, adjustment of purchase price, holdbacks, earn outs or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, assets or Capital Stock of a
Restricted Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such
disposition; 
 (12) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or
similar instrument (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; 

(13) the incurrence by the Company or its Restricted Subsidiaries of Indebtedness consisting of the financing of insurance
premiums in customary amounts consistent with the operations and business of the Company and the Restricted Subsidiaries; and 

(14) in addition to the items referred to in clauses (1) through (13) above, the incurrence by the Company or any
Restricted Subsidiary of additional Indebtedness in an aggregate principal amount which, when taken together with the aggregate principal amount of all other Indebtedness incurred pursuant to this clause (14) and then outstanding, will not
exceed the greater of (i) $150.0 million and (ii) 6% of Consolidated Net Tangible Assets, determined as of the date of each such incurrence, provided, however, that the aggregate principal amount of additional Indebtedness that may be incurred
pursuant to this clause (14) by Restricted Subsidiaries of the Company that are not Guarantors will not exceed $25.0 million. 

(c) The Company will not, and will not permit any Guarantor to, directly or indirectly, incur any Indebtedness which by its terms (or by the
terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or of such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such
Indebtedness) made expressly subordinate to the Notes or the Subsidiary Guarantee of such Guarantor, as the case may be, on substantially the same terms as such Indebtedness is subordinated pursuant to subordination provisions that are most
favorable to the holders of any other Indebtedness of the Company or of such Guarantor, as the case may be. 
 (d) For purposes of
determining compliance with, and the outstanding principal amount of any particular Indebtedness incurred pursuant to and in compliance with, this Section 5.09: 

(1) in the event that Indebtedness meets the criteria of more than one of the categories of Indebtedness described in
Section 5.09(b) or is entitled to be incurred pursuant to Section 5.09(a), the Company, in its sole discretion, will be permitted to divide or classify such item of Indebtedness on the date of incurrence (or later classify, redivide or
reclassify such Indebtedness, in its sole discretion), in any manner that complies with this Section 5.09; 

  
 74 







 (2) notwithstanding the foregoing, any Indebtedness under the Existing Credit
Facilities on the Initial Issuance Date shall be considered incurred under clause (1) or (14) of the definition of Permitted Debt (as applicable) and may not otherwise be reclassified (but may be reclassified and divided from time to time
between such clauses); 
 (3) guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which
is otherwise included in the determination of a particular amount of Indebtedness shall not be included; 
 (4) the principal
amount of any Disqualified Stock of the Company or a Guarantor will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) and the liquidation preference
thereof; 
 (5) Indebtedness permitted by this Section 5.09 need not be permitted solely by reference to one provision
permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 5.09 permitting such Indebtedness; 

(6) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of
the liability in respect thereof determined in accordance with GAAP; and 
 (7) the reclassification of any lease or other
liability of the Company or any of its Restricted Subsidiaries as Indebtedness due to the adoption by the Company after the Initial Issuance Date of a change of accounting principles will not be deemed an incurrence of Indebtedness for purposes of
this covenant. 
 Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of
additional Indebtedness and the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness for purposes of this Section 5.09. The amount of any
Indebtedness outstanding as of any date shall be (1) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (2) the principal amount or liquidation preference thereof, together with any interest
thereon that is more than 30 days past due, in the case of any other Indebtedness. 
 The Company will not permit any of its Unrestricted
Subsidiaries to incur any Indebtedness, other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be
incurred by a Restricted Subsidiary of the Company as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under this Section 5.09, the Company shall be in Default of this Section 5.09). 

  
 75 







 For purposes of determining compliance with any Dollar-denominated restriction on the incurrence
of Indebtedness, the U.S. Dollar Equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of
term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable
Dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such Dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount
of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 5.09, the maximum amount of Indebtedness that the Company or any Restricted
Subsidiary may incur pursuant to this Section 5.09 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. 

SECTION 5.10 Limitation on Asset Sales. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate Collateral Disposition unless: 

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Collateral
Disposition at least equal to the Fair Market Value (provided such Fair Market Value shall be determined (x) as of the date of contractually agreeing to such Collateral Disposition and (y) in good faith by an officer of the Company or, if
the consideration with respect to such Collateral Disposition exceeds $40.0 million, the Board of Directors of the Company) of the Collateral issued or sold or otherwise disposed of; and 

(2) at least 75% of the aggregate consideration received by the Company or its Restricted Subsidiaries in the Collateral
Disposition is in the form of cash or Cash Equivalents; and, 
 (3) the Net Proceeds from any such Collateral Disposition of
Pledged Aircraft and any Aircraft-Related Collateral related to such Pledged Aircraft or of any Capital Stock of a Pledged Equity Subsidiary is paid directly by the recipient thereof to the Collateral Agent to be held in a Collateral Account for
application in accordance with this Section 5.10, 
 provided that in the case of any Collateral Disposition pursuant to a loss, condemnation,
appropriation or similar taking, including by conveyance in lieu of condemnation, such Collateral Disposition shall not be required to satisfy the requirements of items (1) and (2) above. 

Notwithstanding the foregoing requirement of item (3), the Company and the Guarantors will not be required to cause the Net Proceeds from any
Collateral Disposition to be held in a Collateral Account if the amount of Net Proceeds from Collateral Dispositions that would then be held in the Collateral Account would be less than $10.0 million. 

  
 76 







 The Collateral Agent will disburse any amounts on deposit in the Collateral Account in accordance
with an Officers’ Certificate of the Company directing the Collateral Agent to withdraw and transfer any such amount as set forth in such Officers’ Certificate and certifying that the directed use of such amounts is in accordance with this
Section 5.10. 
 Within 365 days after the receipt of any Net Proceeds from Collateral Disposition, the Company or any Restricted
Subsidiary may apply such Net Proceeds (including withdrawing any such Net Proceeds from the Collateral Account) to any combination of the following: 

(1) to permanently repay the principal of any Parity Lien Debt of the Company or any Guarantor; or 

(2) to acquire or invest in (including by way of a purchase of assets or stock, merger, consolidation or otherwise) Productive
Assets that would constitute Collateral or to make a capital expenditure with respect to Collateral; provided that (i) to the extent such Collateral Disposition was of Pledged Aircraft or Aircraft-Related Collateral, any acquisition or
investment in Productive Assets must constitute Pledged Aircraft or Aircraft-Related Collateral (including payments in respect of contracts for purchase or construction of aircraft that will become Pledged Aircraft or Aircraft-Related Collateral
promptly following delivery thereof) and any capital expenditure must be with respect to Pledged Aircraft or Aircraft-Related Collateral if the Aircraft Collateral Asset Value Ratio is less than 1.50: 1.00 immediately prior to giving effect to such
acquisition, investment or expenditure (but only to the extent necessary such that the Aircraft Collateral Asset Value Ratio is at least 1.50:1.00 immediately after giving effect to any such acquisition or investment in Productive Assets that
constitute Pledged Aircraft or Aircraft-Related Collateral) and (ii) Productive Assets shall include Capital Stock of a Foreign Subsidiary only to the extent such Collateral Disposition constituted Capital Stock of a Foreign Subsidiary. 

(b) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale (other than a Collateral
Disposition, which shall be treated in the manner set forth in paragraph (a) above) unless: 
 (1) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value (provided such Fair Market Value shall be determined (i) as of the date of contractually agreeing to such
Asset Sale and (ii) in good faith by an Officer of the Company or, if the consideration with respect to such Asset Sale exceeds $40.0 million, the Board of Directors of the Company) of the assets or Equity Interests issued or sold or
otherwise disposed of; and 
 (2) at least 75% of the aggregate consideration received by the Company or its Restricted
Subsidiaries in the Asset Sale and all other Asset Sales since the Initial Issuance Date is in the form of cash, Cash Equivalents or Marketable Securities; provided, however, that the amount of: 

  
 77 







 (i) any liabilities (as shown on the Company’s or such Restricted
Subsidiary’s most recent balance sheet) of the Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the
transferee of any such assets pursuant to a customary novation or assumption agreement that releases the Company or such Restricted Subsidiary from further liability shall be deemed to be cash for purposes of this provision; and 

(ii) any securities, notes or other obligations (other than Marketable Securities) received by the Company or such Restricted
Subsidiary from such transferee that are converted within 180 days after such Asset Sale by the Company or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion) shall be deemed to be cash for purposes of this
provision; 
 provided that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar taking, including by conveyance in
lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of items (1) and (2) of this Section 5.10(b). 

(c) Within 365 days after the receipt of any Net Proceeds from an Asset Sale (other than a Collateral Disposition, which shall be treated as
provided in clause (a) above), the Company or any such Restricted Subsidiary may apply such Net Proceeds to any combination of the following: 

(1) permanently repay the principal of any senior Indebtedness of the Company or any Restricted Subsidiary; or 

(2) to acquire or invest in (including by way of a purchase of assets or stock, merger, consolidation or otherwise) Productive
Assets or to make a capital expenditure; provided that the requirements of this clause (2) will be deemed to be satisfied if an agreement committing to make the acquisitions, investments or expenditures referred to above is entered into by the
Company or any of its Restricted Subsidiaries within 365 days after the receipt of such Net Proceeds with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment in accordance with such agreement within 180 days
after such 365-day period, and if such Net Proceeds are not so applied within such 180-day period, then such Net Proceeds will constitute Excess Proceeds (as defined
below). 
 (d) Pending the final application of any such Net Proceeds from an Asset Sale not constituting a Collateral Disposition or from
any Collateral Disposition, the Company or any such Restricted Subsidiary may temporarily reduce outstanding revolving credit borrowings, including borrowings under the Credit Facilities, or otherwise invest such Net Proceeds in any manner that is
not prohibited by the Indenture. 

  
 78 







 (e) Any Net Proceeds from Asset Sales pursuant to clause (a) or (b) above that are not
permanently applied or invested as provided for above in this Section 5.10 will be deemed to constitute “Excess Proceeds.” On the 366th day after the Asset Sale (or, at the Company’s option, such earlier date), if the aggregate
amount of Excess Proceeds exceeds $50.0 million, the Company will be required to make an offer (an “Asset Sale Offer”) to all holders of Notes and, (i) with respect to Excess Proceeds from Collateral Dispositions, to the extent
required by the terms of other Parity Lien Debt, to all holders of other Parity Lien Debt outstanding and (ii) with respect to other Excess Proceeds, to the extent required by the terms of all other senior Indebtedness of the Company or any
Restricted Subsidiary, in each case, with similar provisions requiring the Company to make an offer to purchase such Parity Lien Debt or other senior Indebtedness with the proceeds from any Collateral Disposition or Asset Sale, as applicable, to
purchase the maximum principal amount of Notes and any such Parity Lien Debt or such other senior Indebtedness to which the Asset Sale Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to
100% of the principal amount of the Notes and Parity Lien Debt or such other senior Indebtedness, plus accrued and unpaid interest, if any, to the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements
governing the Parity Lien Debt or such other senior Indebtedness, as applicable. To the extent that the aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is less than the amount that the Company is required to repurchase,
the Company may use any remaining Excess Proceeds for any purpose not prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof, other Parity Lien Debt and other senior Indebtedness, as applicable,
surrendered by holders or lenders, collectively, exceeds the amount that the Company is required to repurchase, the Trustee shall select the Notes, Parity Lien Debt and other senior Indebtedness, as applicable to be purchased on a pro rata basis on
the basis of the aggregate principal amount of tendered Notes, Parity Lien Debt and other senior Indebtedness, as applicable (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or
successor may require or, where the nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate), based on the amounts tendered or required to be redeemed (with such
adjustments as may be deemed appropriate by the Company so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero. 
 If the Purchase Date is on or after an interest payment record date and on or before the related
interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no other interest will be payable to Holders who tender Notes pursuant to the
Asset Sale Offer. 
 The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and
any other securities laws or regulations in connection with the repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 5.10 or
Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 5.10 or Section 4.10 by virtue of compliance with such laws and
regulations. 

  
 79 







 SECTION 5.11 Limitation on Transactions with Affiliates. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any properties or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of
the Company involving aggregate payments or consideration in excess of $5.0 million (each of the foregoing, an “Affiliate Transaction”), unless: 

(1) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted
Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary in arm’s-length dealings with an unrelated Person or, if there is no such
comparable transaction, on terms that are fair and reasonable to the Company or such Restricted Subsidiary; and 
 (2) the
Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above; and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $50.0 million, in addition to the Officers’ Certificate referred to above in clause (A), a resolution of the Board of Directors of the Company approved by a majority of the disinterested members thereof; 

provided that the requirements of clause (2) above are not applicable to any Affiliate Transactions in the ordinary course of business with an
Affiliate engaged in the business of providing helicopter transportation services to the oil and gas industry or helicopter search and rescue services (or a business that is reasonably complementary or related to the foregoing). 

(b) The following shall be deemed not to be Affiliate Transactions and, therefore, will not be subject to the provisions of
Section 5.11(a): 
 (1) any employment agreement, employee benefit plan, any other employee compensation plan or
arrangement, officer or director indemnification agreement, severance agreement, consulting agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business, and payments,
awards, grants or issuance of securities pursuant thereto; 
 (2) transactions between or among the Company and its
Restricted Subsidiaries; 

  
 80 







 (3) Permitted Investments and Restricted Payments that are permitted by the
provisions of the Indenture; 
 (4) loans or advances to officers, directors and employees of the Company or any Restricted
Subsidiary made in the ordinary course of business and consistent with past practices of the Company and its Restricted Subsidiaries in an aggregate amount not to exceed $2.0 million outstanding at any one time; 

(5) customary compensation, indemnification and other benefits made available to officers, directors, employees or consultants
of the Company or a Restricted Subsidiary or Affiliate of the Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’
and directors’ liability insurance; 
 (6) transactions with a Person (other than an Unrestricted Subsidiary of the
Company) that is an Affiliate of the Company solely because the Company owns, directly or indirectly, an Equity Interest in, or otherwise controls, such Person; 

(7) any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee an
opinion addressed to the Company or such Restricted Subsidiary, as the case may be, from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from
a financial point of view or that such transaction meets the requirements of clause (1) of Section 5.11(a); 
 (8)
sales of Equity Interests (other than Disqualified Stock) to, or receipt of capital contributions from, Affiliates of the Company; and 

(9) transactions pursuant to agreements or arrangements in effect on the Initial Issuance Date that are described in the
Offering Memorandum or the documents incorporated by reference herein and therein, or any amendment, modification, or supplement thereto or replacement thereof, as long as such agreement or arrangement, as so amended, modified, supplemented or
replaced, is not materially more disadvantageous to the Company and its Restricted Subsidiaries, taken as a whole, than the agreement or arrangement in existence on the Initial Issuance Date. 

SECTION 5.12 Limitation on Liens. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien on any property or asset now owned or hereafter acquired, except Permitted Liens, to secure any Indebtedness of the Company or such Restricted Subsidiary. 

SECTION 5.13 Additional Subsidiary Guarantees. 

If (1) the Company or any of its Restricted Subsidiaries shall, after the Initial Issuance Date, acquire or create another Significant
U.S. Subsidiary or (2) after the Initial Issuance Date, any Restricted Subsidiary that is not a Guarantor shall incur any Indebtedness (including any guarantee of Indebtedness of the Company) except Permitted
Non-Guarantor 

  
 81 







 
Indebtedness, then such newly acquired or created Significant U.S. Subsidiary, in the case of clause (1) above, or such Restricted Subsidiary described in clause (2) above, shall,
within 30 days thereof, execute a supplement to the Indenture providing for a Subsidiary Guarantee and deliver an Opinion of Counsel in accordance with the terms of the Indenture. 

SECTION 5.14 Corporate Existence. 

Subject to Article VI, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its
existence. 
 SECTION 5.15 Offer to Repurchase Upon Change of Control. 

(a) If a Change of Control occurs, the Company will make an offer (a “Change of Control Offer”) to repurchase all or any part
(equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at an offer price in cash equal to 101% of the aggregate principal amount, plus accrued and unpaid interest, if any, to the date of repurchase (the
“Change of Control Payment”). Within 30 days following a Change of Control, the Company will send a notice to each Holder and the Trustee describing the transaction that constitutes the Change of Control and stating: 

(1) that the Change of Control Offer is being made pursuant to this Section 5.15 and that all Notes or portions thereof
properly tendered and not withdrawn will be accepted for payment; 
 (2) the Change of Control Payment and the purchase date,
which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”); 

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

(4) that if the Change of Control Payment Date is on or after an interest payment record date and on or before the related
interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no other interest will be payable to Holders who tender pursuant to the Change of
Control Offer; 
 (5) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted
for payment pursuant to the Change of Control Offer will cease to accrue interest on and after the Change of Control Payment Date; 

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

  
 82 







 (7) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is
withdrawing his election to have the Notes purchased; and 
 (8) that Holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000
in excess thereof. 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities
laws or regulations conflict with provisions of this Section 5.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described in this Section 5.15 by virtue
of compliance with such laws and regulations. 
 A Change of Control Offer may be made in advance of a Change of Control, and conditioned
upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. 

On or before the Change of Control Payment Date, the Company will, to the extent lawful: (1) accept for payment all Notes or portions
thereof properly tendered and not withdrawn 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 such Notes or portions thereof so tendered and not
withdrawn; and (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 

(b) The Paying Agent will promptly send or wire transfer to each Holder of Notes properly tendered and not withdrawn the Change of Control
Payment for such Notes (or if all Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee will promptly authenticate and send (or cause to be transferred by book entry) to each Holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company
will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. If the Change of Control Payment Date is on or after an interest payment record date and on or before the
related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no other interest will be payable to Holders who tender pursuant to the
Change of Control Offer. 

  
 83 







 Payment of the Change of Control Payment for a Note properly tendered and not withdrawn prior to
the expiration of the Change of Control Offer is conditioned upon delivery of such Note (together with necessary endorsements) to the Paying Agent (whether prior to, on or after the Change of Control Payment Date), which delivery may be in
book-entry form in accordance with the Applicable Procedures for Notes issued in global form. The Change of Control Payment for such Note will be made promptly following the later of the Business Day following the Change of Control Payment Date or
the time of delivery of such Note. 
 (c) Notwithstanding anything to the contrary in this Section 5.15, the Company will not be
required to make a Change of Control Offer following a Change of Control if (1) 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 5.15
and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption with respect to all outstanding Notes has been given pursuant to Section 4.08 unless and until there is a default in
payment of the applicable redemption price. 
 (d) In the event that not less than 90% of the aggregate principal amount of the then
outstanding Notes are properly tendered and not withdrawn under a Change of Control Offer and the Company (or the third party making such Change of Control Offer as described above) purchases all such Notes, the Company will have the right, upon not
less than 30 nor more than 60 days’ prior notice to the Holders of the Notes and the Trustee, given not more than 30 days following the Change of Control Payment Date, to redeem all of the Notes that remain outstanding following such purchase
at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, to the date of redemption (subject to the right of
Holders of record on the relevant record date to receive interest due on the relevant interest payment date). Sections 4.01, 4.03, 4.04 and 4.05 shall be applicable to any such redemption. 

SECTION 5.16 No Inducements. 
 The
Company will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any terms or provisions of the Indenture or the Notes, unless such consideration is offered to be paid or agreed to be paid to all Holders which so consent, waive or agree to amend in the time frame set forth in solicitation documents
relating to such consent, waiver or agreement.

ARTICLE VII 
 DEFAULTS AND
REMEDIES 
 SECTION 7.01 Events of Default. 

Each of the following constitutes an “Event of Default” with respect to the Notes: 

(1) a default in the payment when due of interest with respect to the Notes and such default continues for a period of 30 days;

 (2) a default in the payment of the principal of or premium, if any, on the Notes when due at its Stated Maturity, upon

(3) the failure by the Company for 30 days after notice from the Trustee or the Holders of at least 25% in principal amount of
the Notes then outstanding to comply with any of its obligations under Section 5.10 or Section 5.15 (other than a failure to repurchase Notes when due), or failure by the Company to comply with its obligations described under
Section 6.01; 
 (4) the failure by the Company or any of its Restricted Subsidiaries for 60 days after notice from the
Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding to comply with any of its other agreements in the Indenture, the Notes or any Subsidiary Guarantee (provided that, with respect to Section 5.03, the
Company shall have not less than 120 days from the failure to comply with such Section to cure such failure); 

  
 86 







 (5) a default occurs under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries),
whether such Indebtedness or guarantee exists on or is created after the Initial Issuance Date, which default: 
 (i) is
caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness, including any extension thereof (a “Payment Default”); or 

(ii) results in the acceleration of such Indebtedness prior to its Stated Maturity, 

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which
there has been a Payment Default or the maturity of which has been so accelerated, aggregates in excess of $50.0 million; provided that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid,
within a period of 30 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Notes shall be
automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
 (6) the failure by the
Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer
as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 consecutive days; 

(7) the repudiation by any Guarantor of its obligations under its Subsidiary Guarantee or any Subsidiary Guarantee is held in
any judicial proceeding to be unenforceable against a Guarantor for any reason, except, in each case, by reason of the release of such Guarantor in accordance with the Indenture; 

(8) the Company, any Guarantor, or any Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(iv) makes a general assignment for the benefit of its creditors; or 

  
 87 







 (v) admits in writing it generally is not paying its debts as they become due;

(10) the occurrence of any of the following: 

(i) except as permitted by the Note Documents, any Security Document establishing the Parity Liens ceases for any reason to be
enforceable; provided that it will not be an Event of Default under this clause (10)(i) if the sole result of the failure of one or more Security Documents to be fully enforceable is that any Parity Lien purported to be granted under such Security
Documents on Collateral, individually or in the aggregate, having a Fair Market Value of not more than $15.0 million, ceases to be an enforceable and perfected Parity Lien; provided further, that if such failure is susceptible to cure, no Event
of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; 

(ii) except as permitted by the Note Documents, any Parity Lien purported to be granted under any Security Document on
Collateral, individually or in the aggregate, having a Fair Market Value in excess of $15.0 million, ceases to be an enforceable and perfected first-priority Lien, subject to Permitted Liens; provided that if such failure is susceptible to
cure, no Event of Default shall arise with respect thereto until 30 days after any Officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; and 

(iii) the Company or any Guarantor, or any Person validly acting on behalf of any of them, denies or disaffirms, in writing,
any obligation of the Company or any Guarantor set forth in or arising under any Security Document establishing Parity Liens. 

  
 88 







 SECTION 7.02 Acceleration. 

If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then
outstanding Notes may declare all the Notes by notice to the Company (and the Trustee if given by the Holders) to be due and payable immediately. Notwithstanding the preceding sentence, in the case of an Event of Default arising from clause
(8) or (9) of Section 7.01, all outstanding Notes will become due and payable without further action or notice. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on
behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except with respect to nonpayment of principal, interest or premium
that have become due solely because of the acceleration) have been cured or waived. 
 SECTION 7.03 Other Remedies. 

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium,
if any, or interest on the Notes or to enforce the performance of any provision of the Note Documents. 
 The Trustee may maintain a
proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the
right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 

SECTION 7.04 Waiver of Defaults. 

Subject to Sections 7.07 and 10.02, the Holders of a majority in principal amount of the Notes then outstanding by notice to the Trustee may
on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or interest or premium, if any,
on the Notes. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture, but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon. 
 SECTION 7.05 Control by Majority. 

The Holders of a majority in principal amount of the then outstanding Notes will have the right to direct in writing the time, method and
place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it; provided, however that the Trustee may refuse to follow any direction that conflicts with
applicable law or the Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. 

  
 89 







 SECTION 7.06 Limitations on Suits. 

Subject to Section 7.07 hereof, a Holder may pursue a remedy with respect to the Indenture or the Notes or any related Subsidiary
Guarantees only if: 
 (1) the Holder has previously given to the Trustee written notice of a continuing Event of Default;

 (2) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the
Trustee to pursue the remedy; 
 (3) such Holder or Holders offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the request
within 60 days after receipt of the request and the offer of indemnity; and 
 (5) during such
60-day period the Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 

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

SECTION 7.07 Rights of Holders to Receive Payment. 

Notwithstanding any other provision of the Indenture, the contractual right of any Holder of a Note expressly set forth in this Indenture or
the Notes to receive payment of principal of, and premium and interest, if any, on, the Notes (including in connection with a Special Mandatory Redemption), on or after the respective due dates expressed in the Note, or to bring suit for the
enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. 

SECTION 7.08 Collection Suit by Trustee. 

If an Event of Default specified in clause (1) or (2) of Section 7.01 hereof occurs and is continuing, the Trustee is authorized to
recover judgment in its own name and as trustee of an express trust against the Company or a Guarantor for the whole amount of principal, premium and interest, if any, remaining unpaid on the Notes, and interest on overdue principal and premium, if
any, and, to the extent lawful, interest on overdue interest, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel. 
 SECTION 7.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the 

  
 90 







 
Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company or a Guarantor or their respective creditors or properties and shall be entitled and
empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Bankruptcy Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee,
and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 8.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 8.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties
that the Holders of the Notes may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding. 
 SECTION 7.10 Priorities. 

If the Trustee collects any money pursuant to this Article VII, it shall pay out the money in the following order: 

First: to the Trustee, its agents and attorneys for amounts due under Section 8.07 hereof, including payment of all
compensation, expense and liabilities incurred, and all advances made, by the Trustee and the Trustee’s costs and expenses of collection; 

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

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

The Trustee, upon prior written notice to the Company, may fix record dates and payment dates for any payment to Holders pursuant to this
Section 7.10. 
 SECTION 7.11 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted
by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 7.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 7.07, or a suit by a Holder or Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

 ARTICLE VIII 

TRUSTEE 
 SECTION 8.01 Duties of
Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in
it by the Indenture, and use the same degree of care and skill in such 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 duties of the Trustee shall be determined solely by the express provisions of the Indenture and the Trustee need
perform only those duties that are specifically set forth in the Indenture and no others, and no implied covenants or obligations shall be read into the Indenture against the Trustee; and 

(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 certificates or opinions furnished to the Trustee and conforming to the requirements of the Indenture. However, the Trustee shall examine such certificates and opinions to determine whether, on
their face, they appear to conform to the requirements of the 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 Section 8.01(b);

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 it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 7.05. 

(d) Whether or not therein expressly so provided, every provision of the Indenture that in any way relates to the Trustee is subject to the
provisions of this Section 8.01. 
 (e) No provision of the Indenture shall require the Trustee to expend or risk its own funds or incur
any liability. The Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any Holder of Notes, unless such Holder has offered to the Trustee security or indemnity satisfactory
to it against any loss, liability, cots or expense that might be incurred by it in compliance with such request or direction. 

  
 92 







 (f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company and the Guarantors. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. All money received by the Trustee shall, until applied as herein
provided, be held in trust for the payment of the principal of, premium, if any, and interest, if any, on the Notes. 
 SECTION 8.02 Rights of

from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both to be provided. 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. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by
it hereunder in good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and shall not be responsible
for the misconduct or negligence of any agent appointed with due care. 
 (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith that it believes to be authorized or within its rights or powers conferred upon it by this Indenture. 
 (e)
Unless otherwise specifically provided in the Indenture, any demand, request, direction or notice from the Company or any Guarantor shall be sufficient if signed by an Officer of the Company. 

(f) The Trustee shall not be deemed to know or have notice of any 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 or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. When
a Default is cured, it ceases. 
 (g) The permissive rights of the Trustee enumerated herein shall not be construed as duties. 

SECTION 8.03 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, any
Guarantor or any of their respective Affiliates with the same rights it would have if it were not the Trustee. However, in 

  
 93 







 
the event that the Trustee acquires any conflicting interest (as defined in the TIA) after a Default has occurred and is continuing, it must eliminate such conflict within 90 days or resign. Any
Agent may do the same with like rights and duties. The Trustee is subject to Sections 8.10 and 8.11. 
 SECTION 8.04 Trustee’s
Disclaimer. 
 The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of the Indenture or
the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or any Guarantor or upon the Company’s or such Guarantor’s direction under any provision hereof, it shall not
be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other documents in connection with
the sale of the Notes or pursuant to the Indenture, other than its certificate of authentication. 
 SECTION 8.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and it is known to a Responsible Officer of the Trustee, the Trustee shall mail to
Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest, if any, on, any Note, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders. 

SECTION 8.06 [Reserved.] 
 SECTION 8.07
Compensation and Indemnity. 
 The Company agrees to pay to the Trustee for its acceptance of the Indenture and services hereunder
such compensation as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company agrees to reimburse the Trustee
upon request for all reasonable disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

The Company and the Guarantors hereby jointly and severally indemnify the Trustee against any and all loss, liability, damage, claim or
expense, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred by it arising out of or in connection with the acceptance or administration of its duties under the Indenture, including the
costs and expenses of enforcing the Indenture against the Company (including this Section 8.07) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or any other person) or liability in connection
with the exercise or performance of any of its powers or duties hereunder, except as set forth in the next following paragraph. The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company shall not relieve the Company or the Guarantors of their obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent. 

  
 94 







 The Company shall not be obligated to reimburse the Trustee for any expense or indemnify against
any loss or liability incurred by the Trustee to the extent such expense, loss or liability is attributable to the Trustee’s negligence, bad faith or willful misconduct. 

To secure the payment obligations of the Company in this Section 8.07, the Trustee shall have a Lien prior to the Notes on all money or
property held or collected by the Trustee, except that held in trust to pay principal of, or premium, if any, or interest, if any, on particular Notes. Such Lien and the Company’s obligations under this Section 8.07 shall survive the
satisfaction and discharge of the Indenture. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 7.01(8) or (9) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 

SECTION 8.08 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 8.08. 
 The Trustee may resign in writing upon 60 days’ notice at any time
and be discharged from the trust created hereby by so notifying the Company and the Guarantors. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee, the Company and
the Guarantors. The Company may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 8.10; 

(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 Bankruptcy Custodian or public officer takes charge of the Trustee or its property; or 

(4) the Trustee otherwise 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 aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Company. 

  
 95 







 If a successor Trustee does not take office within 30 days after the retiring or removed Trustee
resigns or is removed, the retiring or removed Trustee, the Company, any Guarantor or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee. 
 If the Trustee fails to comply with Section 8.10, any Holder may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee, to the Company and to the Guarantors. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the retiring
Trustee under the Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in
Section 8.07. 
 Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 8.08, the obligations of the
Company under Section 8.07 shall continue for the benefit of the retiring Trustee. 
 SECTION 8.09 Successor Trustee by Merger, etc. 

Subject to Section 8.10, if the Trustee consolidates, 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. 
 In case any
Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 8.10 Eligibility; Disqualification. 

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States, any
State thereof or the District of Columbia and authorized under such laws to exercise corporate trust power, that is subject to supervision or examination by Federal or State (or the District of Columbia) authority and that has a combined capital and
surplus of at least $50.0 million as set forth in its most recent published annual report of condition. 
 The Indenture shall always
have a Trustee who satisfies the requirements of TIA §§ 310(a)(1), 310(a)(2) and 310(a)(5). 

  
 96 







 SECTION 8.11 Preferential Collection of Claims Against the Company or a Guarantor. 

The Trustee is subject to and shall comply with the provisions of TIA § 311(a), excluding any creditor relationship listed in TIA
§ 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 

ARTICLE IX 
 LEGAL DEFEASANCE
AND COVENANT DEFEASANCE 
 SECTION 9.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may, at the option of its Board of Directors evidenced by a Board Resolution, at any time, exercise its rights under either
Section 9.02 or 9.03 hereof with respect to all outstanding Notes upon compliance with the conditions set forth below in this Article IX. 

SECTION 9.02 Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.02, the Company and each of
the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Subsidiary Guarantees) on the
date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes (including the Subsidiary Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 9.05 hereof and the other Sections of the Indenture referred to in
clauses (1) through (4) below, and to have satisfied all their other obligations under such Notes, the Subsidiary Guarantees and the Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and premium, if any, or
interest, if any, on, such Notes when such payments are due solely from the trust referred to in Section 9.04 hereof; 

(2) the Company’s and the Guarantors’ obligations with respect to such Notes under Sections 3.04, 3.05, 3.07, 3.08,
3.11 and 5.02, hereof; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company’s obligations in connection therewith; and 
 (4) this Section 9.02. 

Subject to compliance with this Article IX, the Company may exercise its option under this Section 9.02 notwithstanding the prior
exercise of its option under Section 9.03 hereof. 

  
 97 







 SECTION 9.03 Covenant Defeasance. 

Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.03, the Company and each of
the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from each of their obligations under the covenants contained in Article V (other than those in Sections 5.01, 5.02, 5.06 and 5.14)
and clause (4) of Section 6.01(a) hereof, any covenant added to the Indenture subsequent to the Initial Issuance Date pursuant to Section 10.01 hereof and any covenants contained in the other Note Documents with respect to all
outstanding Notes on and after the date the conditions set forth in Section 9.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of
any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood
that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Subsidiary Guarantees, the Company and the Guarantors may omit to comply with and
will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 7.01 hereof, but, except as specified above, the remainder of the Indenture and such
Notes and Subsidiary Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.03, subject to the satisfaction of the conditions set forth in
Section 9.04 hereof, Sections 7.01(3), (4), (5), (6), (7) and (10) hereof will not constitute Events of Default. 
 SECTION 9.04
Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either
Section 9.02 or 9.03 hereof: 
 (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders, cash in Dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment banking firm, appraisal
firm or firm of independent public accountants, to pay the principal of, and premium and interest, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company
must specify whether such Notes are being defeased to such stated date for payment or to a particular redemption date; 
 (2)
in the case of an election under Section 9.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that: 

(A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or 

  
 98 







 (B) since the Initial Issuance Date, there has been a change in the applicable
federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of
the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have
been the case if such Legal Defeasance had not occurred; 
 (3) in the case of an election under Section 9.03 hereof,
the Company must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a
result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting of Liens to secure such borrowings); 

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any
material agreement or instrument (other than the Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or
any of its Restricted Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officers’ Certificate
stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and 

(7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 SECTION 9.05 Deposited
Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 9.06 hereof, all money
and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 9.05 and Section 12.02, the
“Trustee”) pursuant to Section 9.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such
money need not be segregated from other funds except to the extent required by law. 

  
 99 







 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or non-callable Government Securities deposited pursuant to Section 9.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article IX to the
contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 9.04 hereof
which, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under
Section 9.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

If the Company exercises either its Legal Defeasance or Covenant Defeasance option, each Guarantor will be released and relieved of any
obligations under its related Subsidiary Guarantee and any Collateral or security for the Notes (other than the trust) and the other Notes Obligations will be released. 

SECTION 9.06 Repayment to Company. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or
premium, if any, or interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall, subject to any applicable abandoned property laws, be paid to the
Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense
of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 SECTION 9.07
Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any Dollars or
non-callable Government Securities in accordance with Section 9.02 or 9.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations 

  
 100 







 
under the Indenture and the Notes and the Subsidiary Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 9.02 or 9.03 hereof until such time as
the Trustee or Paying Agent is permitted to apply all such money or non-callable Government Securities in accordance with Section 9.02 or 9.03 hereof, as the case may be; provided, however,
that, if the Company or any Guarantor makes any payment of principal of, or premium, if any, or interest, if any, on, any Note following the reinstatement of its obligations, the Company or such Guarantor, as applicable, will be subrogated to the
rights of the Holders of such Notes to receive such payment from the money or non-callable Government Securities held by the Trustee or Paying Agent. 

ARTICLE X 
 SUPPLEMENTAL
INDENTURES AND AMENDMENTS 
 SECTION 10.01 Without Consent of Holders. 

Notwithstanding Section 10.02 of this Indenture, without the consent of any Holder, the Company, the Guarantors, the Trustee and, if
applicable, the Collateral Agent may amend the Indenture or the Notes or the Security Documents: 
 (1) to cure any
ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of Definitive
Notes; 
 (3) to provide for the assumption of the Company’s obligations to the Holders in the case of a merger or
consolidation or sale of all or substantially all of the Company’s properties or assets; 
 (4) to make any change that
would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under the Indenture of any such Holder; 

(5) to add additional security for the Notes and/or other Parity Lien Obligations; 

(6) to add any additional Guarantor or to release any Guarantor from its Subsidiary Guarantee, in each case as provided in the
Indenture; 
 (7) to comply with requirements of the Commission in order to effect or maintain the qualification of the
Indenture under the TIA; 
 (8) to conform the text of the Indenture, the Notes, the Subsidiary Guarantees or any Note
Document to any provision of the “Description of the Notes” section of the Offering Memorandum, to the extent that such provision in such “Description of the Notes” was intended to be a substantially verbatim recitation of a
provision of the Indenture, the Notes, the Subsidiary Guarantees or any Note Document, which intent may be evidenced by an Officers’ Certificate to that effect; 

  
 101 







 (9) to provide for the issuance of Additional Notes in accordance with the
limitations set forth in the Indenture; 
 (10) to evidence or provide for the acceptance of appointment under the Indenture
of a successor Trustee; 
 (11) to release, discharge or terminate Liens on Collateral in accordance with the Note Documents
and to confirm and evidence any such release, discharge or termination; or 
 (12) with respect to the Security Documents, as
provided in the Collateral Agency Agreement. 
 Upon the request of the Company, and upon receipt by the Trustee of the documents described
in Section 10.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements
and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 

SECTION 10.02 With Consent of Holders. 

(a) Except as provided below in Section 10.02(b), the Company, the Guarantors, the Trustee and, if applicable, the Collateral Agent may
amend or supplement the Indenture and the Notes and the Security Documents with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase
of, or tender offer or exchange offer for, the Notes), and, subject to Sections 7.04 and 7.07 hereof, any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes and the Security Documents may be waived
with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes) in each case in addition to
any required consent of holders of other Parity Lien Obligations required with respect to any amendment or waiver under any Security Document. Sections 3.08 and 3.09 hereof shall determine which Notes are considered to be
“outstanding” for purposes of this Section 10.02. 
 Upon the request of the Company, and upon the filing with the Trustee of
evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 10.06 hereof, the Trustee shall join with the Company and the Guarantors in the
execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental indenture. 
 It shall not be necessary for the consent of the Holders
under this Section 10.02 to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. A consent to any amendment or
waiver under the Indenture by any Holder given in connection with a purchase, tender or exchange of such Holder’s Notes will not be rendered invalid by such purchase, tender or exchange. 

  
 102 







 After an amendment, supplement or waiver under this Section 10.02 becomes effective, the
Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity
of any such amendment, supplement or waiver. 
 (b) Notwithstanding Section 10.02(a), without the consent of each Holder affected, an
amendment, supplement or waiver under this Section 10.02 may not (with respect to any Notes held by a non-consenting Holder): 

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

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption or
repurchase of the Notes (other than the provisions of Section 5.10 or 5.15); 
 (3) reduce the rate of or change the
time for payment of interest on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or
premium or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 

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

(6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders to receive
payments of principal of, or premium or interest on the Notes (except as permitted in clause (7) hereof); 
 (7) waive a
redemption or repurchase payment with respect to any Note (other than a payment required by Section 5.10 or 5.15); 

(8) make any change in the ranking of the Notes or the Subsidiary Guarantees relative to other Indebtedness of the Company or
the Guarantors, respectively, in either case in a manner adverse to the Holders; 
 (9) modify the Subsidiary Guarantees in
any manner materially adverse to the Holders or release any Guarantor from any of its obligations under its Subsidiary Guarantee or the Indenture, except in accordance with the terms of the Indenture; or 

  
 103 







 (10) make any change in the preceding amendment, supplement and waiver
provisions. 
 In addition, the consent of Holders representing at least two-thirds in principal
amount of the outstanding Notes will be required to release the Liens for the benefit of the Holders of the Notes on all or substantially all of the Collateral, other than in accordance with the Note Documents. 

SECTION 10.03 Effect of Supplemental Indentures. 

Upon the execution of any supplemental indenture under this Article X, the Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 

SECTION 10.04 Compliance with Trust Indenture Act. 

Every amendment or supplement to the Indenture or the Notes shall comply in form and substance with the TIA as then in effect. 

SECTION 10.05 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to
his or her Note or portion of a Note if the Trustee receives written notice of revocation before a date and time therefor identified by the Company or any Guarantor in a notice furnished to such Holder in accordance with the terms of the Indenture
or, if no such date and time shall be identified, the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

The Company or any Guarantor may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to
consent to any amendment, supplement or waiver or to take any other action under the Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date
(or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No
consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of Securities required hereunder for such amendment, supplement or waiver to be effective shall have also been
given and not revoked within such 90-day period. 
 After an amendment, supplement or waiver becomes
effective, it shall bind every Holder, unless it is of the type described in Section 10.02(b) hereof. In such case, the amendment, supplement or waiver shall bind only each Holder who has consented to it and every subsequent Holder that
evidences the same debt as the consenting Holder’s Note. 

  
 104 







 SECTION 10.06 Notation on or Exchange of Notes. 

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

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

 SECTION 10.07 Trustee to Sign Amendments, etc. 

The Trustee shall sign any amendment or supplement authorized pursuant to this Article X if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment or supplement, the Trustee shall be entitled to receive, and, shall be fully
protected in relying upon in good faith, an Officers’ Certificate and an Opinion of Counsel provided at the expense of the Company or a Guarantor as conclusive evidence that such amendment or supplement is authorized or permitted by the
Indenture. 
 ARTICLE XI 

SUBSIDIARY GUARANTEES 
 SECTION 11.01
Subsidiary Guarantee. 
 (a) For value received, each Guarantor hereby jointly and severally fully, unconditionally and absolutely
guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest, if any, on the Notes and all other amounts due and payable under
the Indenture and the Notes by the Company, when and as such principal, premium and interest shall become due and payable, subject to any applicable grace period, whether at maturity or by declaration of acceleration, call for redemption or
otherwise, according to the terms of the Notes and the Indenture and, in the case of any extension of time of payment or renewal of any Notes, when the same shall become due and payable in accordance with the terms of the extension or renewal,
subject to any applicable grace period, whether at maturity or by declaration or acceleration, call for redemption or otherwise, in each case, subject to the limitations set forth in Section 11.02. 

(b) Failing payment when due of any amount guaranteed pursuant to the related Subsidiary Guarantee, for whatever reason, each of the Guarantors
will be jointly and severally obligated to pay the same immediately. Each of the Guarantors hereby agrees that its obligations hereunder shall be full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the
Notes, its Subsidiary Guarantee, the Subsidiary Guarantee of any other Guarantor or the Indenture, the absence of any action to enforce the same, any waiver 

  
 105 







 
or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company or any Guarantor, or any action to enforce the same or any other
circumstances (other than payment) which might otherwise constitute a legal or equitable discharge or defense of the Guarantors. Each of the Guarantors hereby agrees that in the event of a default in payment of the principal of, or premium, if any,
or interest on the Notes, whether at maturity or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to Section 7.06, by the Holders, on the
terms and conditions set forth in the Indenture, directly against such Guarantor to enforce such Subsidiary Guarantee without first proceeding against the Company or any other Guarantor. 

(c) The obligations of each of the Guarantors under this Article XI shall be as aforesaid full, unconditional and absolute and shall not be
impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the
obligations and liabilities of the Company or any of the Guarantors contained in the Notes or the Indenture, (ii) any impairment, modification, release or limitation of the liability of the Company, any of the Guarantors or any of their estates
in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the decision of any court, (iii) the assertion or
exercise by the Company, any of the Guarantors or the Trustee of any rights or remedies under the Notes or the Indenture or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the purported
assignment of any property as security for the Notes, including all or any part of the rights of the Company or any of the Guarantors under the Indenture, (v) the extension of the time for payment by the Company or any of the Guarantors of any
payments or other sums or any part thereof owing or payable under any of the terms and provisions of the Notes or the Indenture or of the time for performance by the Company or any of the Guarantors of any other obligations under or arising out of
any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or any of the Guarantors set forth in the
Indenture, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Company or any of the Guarantors or any of their respective assets, or the disaffirmance of the Notes, the Subsidiary Guarantees or
the Indenture in any such proceeding, (viii) the release or discharge of the Company or any of the Guarantors from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of
law, (ix) the unenforceability of the Notes, the related Subsidiary Guarantees or the Indenture or (x) any other circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the related Subsidiary
Guarantees) which might otherwise constitute a legal or equitable discharge of a surety or guarantor. 
 (d) Each of the Guarantors hereby
(i) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or any of the Guarantors, and all demands whatsoever and (ii) covenants that its
Subsidiary Guarantee will not be discharged except by complete performance of such Subsidiary 

  
 106 







 
Guarantee. Each of the Guarantors further agrees that if at any time all or any part of any payment theretofore applied by any Person to its Guarantee is, or must be, rescinded or returned for
any reason whatsoever, including, without limitation, the insolvency, bankruptcy or reorganization of the Company or any of the Guarantors, such Subsidiary Guarantee shall, to the extent that such payment is or must be rescinded or returned, be
deemed to have continued in existence notwithstanding such application, and such Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made. 

(e) Each of the Guarantors shall be subrogated to all rights of the Holders and the Trustee against the Company in respect of any amounts paid
by such Guarantor pursuant to the provisions of the Indenture; provided, however, that such Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until all of the
Notes and the related Subsidiary Guarantees shall have been paid in full or discharged. 
 SECTION 11.02 Guarantors May Consolidate, etc. on Certain
Terms. 
 No Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person
(other than the Company or another Guarantor), whether or not affiliated with such Guarantor, unless: 
 (1) the Person
formed by or surviving any such consolidation or merger (if other than such Guarantor) shall execute a supplement to the Indenture providing for a Subsidiary Guarantee and such Security Documents as shall be required to maintain a perfected Lien on
the Collateral owned or held by such Guarantor and deliver an Opinion of Counsel with respect to the foregoing in accordance with the terms of the Indenture; and 

(2) immediately after giving effect to such transaction, no Default or Event of Default exists. 

Upon any such consolidation or merger of a Guarantor and upon the execution by the successor Person of a supplemental indenture, executed by
the Trustee, providing for a Subsidiary Guarantee, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. 

SECTION 11.03 Limitation on Liability of the Guarantors. 

Each Guarantor and by its acceptance hereof each Holder hereby confirms that it is the intention of all such parties that the guarantee by
such Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state law. To effectuate the foregoing intention, the Holders and the Guarantors hereby irrevocably agree that the
obligations of each Guarantor under its Subsidiary Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and to any collections from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under federal or state law. 

  
 107 







 SECTION 11.04 Release of Guarantors from Subsidiary Guarantee. 

Notwithstanding any other provisions of the Indenture, each Guarantor will be automatically and unconditionally released and relieved of any
obligations under its Subsidiary Guarantee and any Security Documents to which it is a party, and its Capital Stock will be released from the Liens of the Security Documents: 

(1) upon a sale or other disposition (including by way of merger or consolidation) of all or substantially all of the assets of
such Guarantor or all of the Capital Stock of such Guarantor owned by the Company or its Subsidiaries to a Person other than the Company or a Restricted Subsidiary; provided, however, that the Net Proceeds of such sale or disposition
are applied in accordance with Sections 4.10 and 5.10; 
 (2) upon Legal Defeasance or Covenant Defeasance in accordance with
Article IX, or upon satisfaction and discharge of the Indenture in accordance with Article XII; 
 (3) upon the Board of
Directors designating such Guarantor as an Unrestricted Subsidiary; provided, however, that such designation is conducted in accordance with the Indenture; or 

(4) provided that no Default or Event of Default shall have occurred and shall be continuing, (i) upon the liquidation or
dissolution of such Guarantor or (ii) at such time as such Guarantor ceases both (x) to be a Restricted Subsidiary and (y) to be an obligor with respect to any Indebtedness the incurrence of which resulted in or would result in the
obligation of such Guarantor to guarantee the Notes under the Indenture. 
 The Trustee shall deliver an appropriate instrument evidencing
any release of a Guarantor from its Subsidiary Guarantee and other Note Documents, as applicable, upon receipt of a written request of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel that the Guarantor is entitled
to such release in accordance with the provisions of the Indenture. If the Guarantor is not so released it shall remain liable for the full amount of principal of, and premium, if any, and interest, on the Notes, subject to the limitations of
Section 11.03. 
 SECTION 11.05 Contribution. 

In order to provide for just and equitable contribution among the Guarantors, the Guarantors hereby agree, inter se, that in the event any
payment or distribution is made by any Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Guarantor (as applicable) in a pro rata amount based
on the net assets of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Notes or any other Guarantor’s
obligations with respect to its Subsidiary Guarantee of the Notes. 

  
 108 







 SECTION 11.06 Execution and Delivery of Guaranty.  

The execution by each Guarantor of this Indenture (or a further supplemental indenture) evidences the Subsidiary Guaranty of such Guarantor,
whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Subsidiary Guaranty set
forth in this Indenture on behalf of each Guarantor. 
 ARTICLE XII 

SATISFACTION AND DISCHARGE 
 SECTION 12.01
Satisfaction and Discharge. 
 (a) The Indenture and the other Note Documents shall cease to be of further effect with respect to the
Notes (except that the Company’s obligations under Section 8.07, the Trustee’s and Paying Agent’s obligations under Section 9.06 and the rights, powers, protections and privileges accorded the Trustee under Article VIII
shall survive), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging the satisfaction and discharge of this Indenture with respect to the Notes and the other Note Documents, when: 

(1) either: 

(i) all outstanding Notes theretofore authenticated and issued (other than destroyed, lost or stolen Notes that have been
replaced or paid) have been delivered to the Trustee for cancellation; or 
 (ii) all outstanding Notes not theretofore
delivered to the Trustee for cancellation: 
 (1) have become due and payable, or 

(2) will become due and payable at their Stated Maturity within one year, or 

(3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company, 
 and, in the case of clause (i), (ii) or (iii) above, the
Company or a Guarantor has irrevocably deposited or caused to be deposited with the Trustee as funds (immediately available to the Holders in the case of clause (i)) in trust for such purpose cash in Dollars,
non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent
public accountants, to pay and discharge the entire Indebtedness on the Notes for principal and interest to the date of such deposit (in the case of Notes which have become due and payable) or for principal, premium, if any, and interest, if any, to
the stated date for payment thereof or on the applicable redemption date, as the case may be; 

  
 109 







 (2) the Company or a Guarantor has paid or caused to be paid all other sums
payable by them hereunder with respect to the Notes; and 
 (3) the Company has delivered to the Trustee an Officers’
Certificate stating that all conditions precedent to satisfaction and discharge of the Indenture with respect to the Notes have been complied with, together with an Opinion of Counsel to the same effect. 

SECTION 12.02 Application of Trust Money. 

Subject to Section 9.06 hereof, all money and non-callable Government Securities (including the
proceeds thereof) deposited with the Trustee pursuant to Section 12.01 hereof will be held in trust and applied by the Trustee, in accordance with the provisions of the Notes and the Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, and interest, if any, for whose payment such money has been deposited with the
Trustee, but such money need not be segregated from other funds except to the extent required by law. 
 Notwithstanding anything in this
Article XII to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in
Section 12.01 which are in excess of the amount thereof that would then be required to be deposited to effect the satisfaction and discharge of the Indenture pursuant to Section 12.01. 

SECTION 12.03 Reinstatement. 
 If
the Trustee or Paying Agent is unable to apply any Dollars or non-callable Government Securities in accordance with Section 12.01 hereof by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under the Indenture and the Notes and the Subsidiary Guarantees will be revived and reinstated as though no
deposit had occurred pursuant to Section 12.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money or non-callable Government Securities in accordance with
Section 12.01 hereof, as the case may be; provided, however, that, if the Company or any Guarantor makes any payment of principal of, premium, if any, or interest, if any, on, any Note following the reinstatement of its
obligations, the Company or such Guarantor, as applicable, will be subrogated to the rights of the Holders to receive such payment from the money or non-callable Government Securities held by the Trustee or
Paying Agent.

 ARTICLE XIII 

COLLATERAL AND SECURITY 
 SECTION 13.01
Security Interest. 
 (a) The due and punctual payment of the principal of, premium on, if any, and interest if any, on the Notes and
the Obligations of Guarantors under the Subsidiary Guarantees, when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue
principal of, premium on, if any, and interest, if any (to the extent permitted by law), on the Notes and Subsidiary Guarantees under and performance of all other obligations of the Company and the Guarantors to the Holders of Notes or the Trustee
under the Note Documents, according to the terms hereunder or thereunder (collectively, the “Notes Obligations”), shall be secured by Liens on the Collateral as provided in the Security Documents. The Company and each of the
Guarantors consent and agree to be bound by the terms of the Security Documents to which they are parties, as the same may be in effect from time to time, and agree to perform their obligations thereunder in accordance therewith, and hereby agree
that the Collateral Agent shall hold the Collateral on behalf of and for the benefit of all of the Holders of Notes and the other holders of Parity Lien Obligations. 

(b) Each Holder of Notes, by its acceptance thereof and of the Subsidiary Guarantees, consents and agrees to the terms of the Collateral Agency
Agreement and the other Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and amendments to the Security Documents) as the same may be in effect or may be amended from time to time
in accordance with their terms and authorizes and appoints U.S. Bank National Association as the Trustee and as the Collateral Agent. The Trustee hereby authorizes and appoints U.S. Bank National Association as Collateral Agent and each Holder of
Notes and the Trustee direct the Collateral Agent to enter into the Security Documents (including any amendments thereto contemplated by the Collateral Agency Agreement and any security documents to secure additional Parity Lien Debt in accordance
with the Collateral Agency Agreement) and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof, including, without limitation, the limitations on duties of the Collateral
Agent provided in Section 6(f) of the Collateral Agency Agreement. The Trustee, the Collateral Agent and each Holder of Notes, by accepting the Notes and the Subsidiary Guarantees, acknowledges that, as more fully set forth in the Security
Documents, the Collateral as now or hereafter constituted shall be held for the benefit of all the holders of Parity Lien Obligations, subject to the Collateral Agency Agreement, and the Lien of this Indenture and the Security Documents is subject
to and qualified and limited in all respects by the Collateral Agency Agreement and the Security Documents and actions that may be taken thereunder. 

(c) Subject to the provisions of Article VII and Article VIII of this Indenture and the terms of the Security Documents (including any consent
of the Holders required thereunder), the Trustee may direct, on behalf of the Holders of Notes, the Collateral Agent to take all actions it deems necessary or appropriate in order to enforce any of the terms of the Security Documents and the
Collateral Agency Agreement and collect and receive any and all amounts payable in respect of the Notes Obligations of the Company or any Guarantor hereunder. 

  
 111 







 SECTION 13.02 Security Documents; Post-Closing Perfection. 

(a) Promptly after the date hereof, but in any event no later than on the Post-Closing Aircraft Liens Perfection Date, the Company and the
Guarantors will execute and deliver to the Collateral Agent the following documents, each in form and substance reasonably satisfactory to the Trustee and the Collateral Agent: (i) fully executed and certified (as required by the applicable
law) aircraft security agreements or supplements thereto constituting Security Documents, with respect to each of (x) the Pledged Aircraft and (y) Engines constituting the Aircraft-Related Collateral (such Engines, collectively with the
Pledged Aircraft, “Registered Aircraft-Related Collateral”), as may be necessary to create a valid, perfected first priority Lien (subject to Permitted Collateral Liens) in such Registered Aircraft-Related Collateral in favor of the
Collateral Agent for the benefit of the Parity Lien Secured Parties; (ii) lien search results with respect to Registered Aircraft-Related Collateral in the International Registry (Priority Search Certificates issued by the International
Registry) and the records and registries maintained by each applicable authority in each Jurisdiction of Registration of the Registered Aircraft-Related Collateral, each as of a recent date showing that the title to such Registered Aircraft-Related
Collateral belongs to the Company or any Guarantor free and clear of any Liens (other than the Permitted Collateral Liens); (iii) evidence of all registrations with the International Registry necessary or appropriate to create and perfect the Liens
granted by such Security Documents with respect to the Registered Aircraft-Related Collateral; (iv) filing opinions of counsel or other customary evidence of the completion of all applicable filings or recordings of such Security Documents and
other necessary documents with the applicable aviation authority necessary or appropriate to create and perfect the Liens granted by such Security Documents, and any other filings or notices required to be made with any other government authority or
registry in the Jurisdiction of Registration of the respective Registered Aircraft-Related Collateral, (v) certificates of insurance issued by the Company’s or the applicable Guarantor’s broker, (x) describing in reasonable
detail the insurance maintained in respect of the Pledged Aircraft, (y) naming the Collateral Agent as loss payee, in the case of hull insurance, and additional insured, in the case of other insurance coverage and (z) providing that the
respective insurers irrevocably waive any and all rights of subrogation with respect to the Collateral Agent and the other Parity Lien Secured Parties, (vi) a written legal post-recordation opinion of the Company’s or the applicable
Guarantor’s aircraft title counsel in the relevant Jurisdiction of Registration of the applicable Registered Aircraft-Related Collateral with respect to enforceability, creation, perfection of the foregoing Liens, provided that in certain
Jurisdictions of Registration, where the Company or the applicable Guarantor’s aircraft title counsel is not permitted to deliver such an opinion to the Collateral Agent by operation of law, the requirement of this clause (vi) may be
satisfied if the Collateral Agent is able obtain such opinions from its aircraft title counsel for the applicable jurisdiction and (vii) evidence of payment by the Company of all premiums, search and examination charges and related charges,
filing or recording taxes, fees, charges, costs and expenses required for the recording of the Liens referred to above. 

  
 112 







 (b) For all purposes of the foregoing and any other provision of the Note Documents, if a Pledged
Aircraft is operated by a lessee in Canada, the Collateral Agent’s Lien on such Pledged Aircraft and other related Registered Aircraft-Related Collateral shall be deemed to be a perfected first priority Lien if two notices are filed in the
Personal Property Registry of the operator’s province of organization, each identifying such Registered Aircraft-Related Collateral, one notice designating the operator as the debtor and the owner and the Collateral Agent as the secured party
and the other notice designating the operator and the owner as the debtors and the Collateral Agent as the secured party. 
 (c)
Notwithstanding anything to the contrary contained herein or any other Note Document, if, after the exercise of commercially reasonable efforts, the Company or the applicable Guarantor is not able to deliver any curative documentation that would
support the removal from an aircraft title opinion of exceptions to title to Registered Aircraft-Related Collateral by the Post-Closing Aircraft Liens Perfection Date by reason of a title defect, the Company and the relevant Guarantor shall not be
obligated to deliver any such curative documentation, to the extent that the value of such curative documentation with respect to all Registered Aircraft-Related Collateral does not exceed $15,000,000 in the aggregate (1) based on the impact on
fair market value of such title exceptions as they relate to the airframe constituting the relevant Registered Aircraft-Related Collateral and (2) with respect to Engine title exceptions, the fair market value of such title exceptions as they
relate to each affected such Engine constituting the relevant Registered Aircraft-Related Collateral. The term “fair market value” as used in this clause (c) shall be as defined in the definition of Aircraft Collateral Asset Value
Ratio. 
 SECTION 13.03 After Acquired Collateral; Further Assurances 

(a) From and after the Initial Issuance Date and subject to certain limitations and exceptions, if property (other than Excluded
Assets) (x) is acquired by the Company or any Guarantor or (y) ceases to constitute Excluded Assets, in each case, that is not automatically subject to a perfected security interest under the Security Documents, or a Restricted Subsidiary
(including a newly created or newly acquired Subsidiary) becomes a Guarantor, then the Company or Guarantor will, as soon as reasonably practicable and in any event within 90 days after such property’s acquisition or it no longer being an
Excluded Asset or such person becoming a Guarantor, grant Liens on such property (or, in the case of a new Guarantor, all of its assets except Excluded Assets) in favor of the Collateral Agent (and, to the extent such grant would require the
execution and delivery of a Security Document, the Company or such Guarantor shall execute and deliver such Security Document on substantially the same terms as the Security Documents covering Collateral owned by the Company and Guarantors on the
Initial Issuance Date); provided that the Company and Guarantors shall not be required to grant Liens on aircraft and Aircraft-Related Collateral acquired following the Initial Issuance Date (whether the aircraft and Aircraft-Related
Collateral (i) be acquired by an existing Guarantor or a Restricted Subsidiary that becomes a Guarantor (including a newly created or acquired Subsidiary), (ii) be acquired from an Affiliate or a third-party seller, (iii) be under contract
for purchase or construction on the Initial Issuance Date or (iv) ceases to be Excluded Assets), except that if on any Aircraft Collateral Testing Date the Aircraft Collateral Asset Value Ratio is less than 1.50:1.00, the Company and Guarantors
shall be required to grant Liens as promptly as practicable on aircraft and Aircraft-Related Collateral (except to the extent constituting an Excluded Asset pursuant to clause (1) or (7) of the definition thereof) acquired on or following such
Aircraft Collateral Testing Date until such time as the Aircraft Collateral Asset Value Ratio would equal or exceed 1.50:1.00 (calculated giving effect to the pledge of any additional aircraft 

  
 113 







 
and Aircraft-Related Collateral since the relevant Aircraft Collateral Testing Date); provided further that if (x) the Company or a Guarantor acquires an aircraft from a Subsidiary
that is not a Guarantor for the purpose of facilitating the marketing and/or sale of such aircraft to a third party (as evidenced by an Officers’ Certificate delivered to the Collateral Agent) and (y) the preceding proviso would require
the Company and Guarantors to grant Liens on such aircraft and the related Aircraft-Related Collateral, then the Company and Guarantors shall be required to grant such Liens no earlier than 180 days after such acquisition and only if the Company or
a Guarantor then owns such aircraft. With respect to any such aircraft subject to a contract for purchase or construction and any applicable Aircraft-Related Collateral, such aircraft and its related Aircraft-Related Collateral shall not be deemed
to be “acquired” until such time that the Company or a Guarantor takes both physical possession and title thereto. 
 (b) Except as
otherwise provided herein, the Company and each of the Guarantors shall do or cause to be done all acts and things that may be required, or that the Collateral Agent from time to time may reasonably request, to assure and confirm that the Collateral
Agent holds, for the benefit of the Parity Lien Secured Parties, duly created and enforceable and perfected Liens upon the Collateral (including any acquired property or other property required by this Indenture or any Security Document to become,
Collateral after the Initial Issuance Date or Post-Closing Aircraft Liens Perfection Date, as applicable), in each case, as contemplated by, and with the Lien priority required under, the Parity Lien Documents, and in connection with any merger,
consolidation or sale of assets of the Company or any Guarantor, the property and assets of the Person which is consolidated or merged with or into the Company or any Guarantor, to the extent that they are property or assets of the types which would
constitute Collateral under the Security Documents, shall be treated as after-acquired property and the Company or such Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the
Parity Liens, in the manner and to the extent required under the Security Documents. 
 (c) Without limiting the foregoing, at any time and
from time to time, the Company and each of the Guarantors shall promptly execute, acknowledge and deliver such Security Documents, instruments, certificates, financing statements, notices and other documents, and take such other actions as shall be
reasonably required, or that the Collateral Agent may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Security Documents for the benefit of the
Parity Lien Secured Parties; provided, that no such Security Document, instrument or other document shall be materially more burdensome upon the Company and the Guarantors than the Parity Lien Documents executed and delivered (or required to be
executed and delivered after the date of this Indenture, including pursuant to Section 13.02) by the Company and the Guarantors in connection with the Initial Issuance Date. 

(d) Notwithstanding anything to the contrary contained herein or in any other Note Document, Liens on the Collateral will not be required to be
perfected if such Liens cannot be perfected by filing of UCC-1 statements (including with respect to commercial tort claims), the recording or filing of aircraft security agreements or supplements thereto, the
delivery of certificates evidencing Capital Stock or promissory notes and control agreements with respect to any Pledged Account, and any reference in the Note Documents to perfected Liens shall be a reference only to such methods of perfection.


  
 114 







 (e) Notwithstanding anything herein or in the Note Documents to the contrary, neither the Company
nor any Guarantor will be required to grant a security interest in, and the Collateral shall not include, any Excluded Asset. 
 (f) The
Company will deliver to the Trustee copies of all documents delivered to the Collateral Agent pursuant to the Security Documents. 
 (g)
Aircraft Substitutions shall be permitted after the Initial Issuance Date so long as the Company or the Guarantor that is the owner and pledgor of the Eligible Aircraft being substituted satisfies the conditions with respect thereto, as if such
Eligible Aircraft had been a Pledged Aircraft on the Initial Issuance Date or the Applicable Post-Closing Aircraft Liens Perfection Date, as applicable, contemporaneously with the consummation of such Aircraft Substitution and takes such other
actions in connection therewith as would otherwise have been required to be taken pursuant to this Article XIII and the Security Documents had the substituted Eligible Aircraft been a Pledged Aircraft on the Initial Issuance Date or the Applicable
Post-Closing Aircraft Liens Perfection Date, as applicable. 
 (h) To the extent any grant of security required hereby would require the
execution and delivery of a Security Document, the Company or such Guarantor shall execute and deliver such Security Document, together with related certificates and opinions with respect thereto, on substantially the same terms as the Security
Documents covering Collateral owned by the Company and Guarantors on the Initial Issuance Date or the Applicable Post-Closing Aircraft Liens Perfection Date, as applicable (in the case of aircraft and Aircraft-Related Collateral, with such changes
as may be necessary, advisable or appropriate to reflect the Jurisdiction of Registration of the applicable aircraft). 
 SECTION 13.04 The
Collateral Agency Agreement 
 This Article XIII and the provisions of each other Security Document are subject to the terms, conditions
and benefits set forth in the Collateral Agency Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Collateral Agency Agreement, as the same may be in effect from time to time, and to perform its
obligations thereunder in accordance with the terms therewith. Each Holder of Notes, by its acceptance of the Notes (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Agency Agreement and
(b) authorizes and instructs the Collateral Agent on behalf of each Holder to enter into the Collateral Agency Agreement as Collateral Agent on behalf of such Holders. 

SECTION 13.05 Release of Liens in Respect of Notes 

The Collateral Agent’s Liens upon the Collateral will no longer secure the Notes or any other Notes Obligations, and the right of the
Holders of the Notes to the benefits and proceeds of the Collateral Agent’s Liens on the Collateral will terminate and be released: 

(1) upon payment in full of principal, interest and all other Obligations on the Notes or satisfaction and discharge of the
Indenture pursuant to Article XII or Legal Defeasance or Covenant Defeasance in accordance with Article IX; 

  
 115 







 (2) upon release of a Subsidiary Guarantee (with respect to the Liens securing
such Subsidiary Guarantee granted by such Guarantor and to the extent the Capital Stock is no longer owned directly by the Company or a Restricted Subsidiary, immediately after giving effect to the transaction or transactions giving rise to the
relevant Subsidiary Guarantee release, the Liens on the Capital Stock of such Guarantor); 
 (3) in connection with any
disposition of Collateral to any Person other than the Company or any of its Restricted Subsidiaries that is permitted by this Indenture (with respect to the Lien on such Collateral); 

(4) with respect to any Pledged Aircraft and any Aircraft-Related Collateral related thereto, upon the request and at the
election of the Company, if immediately after giving effect to such release, the Aircraft Collateral Asset Value Ratio would exceed 1.50:1.00; 

(5) as to any Collateral that is the subject of an Aircraft Substitution or is a Relinquished Engine; and 

(6) in whole or in part, with the consent of the holders of the requisite percentage of Notes in accordance with the provisions
described under Article X. 
 In addition, the Collateral Agent’s Liens on the Collateral will terminate and be released in accordance
with Section 7 of the Collateral Agency Agreement. 
 Upon compliance by the Company or any Guarantor, as the case may be, with the
conditions precedent required by the Indenture and the Collateral Agency Agreement, the Collateral Agent shall promptly cause the released Collateral to be released and re-conveyed to the Company or the
Guarantor, as the case may be and shall timely execute such releases of Liens and aircraft security agreement supplements as are required by the Indenture and the other Security Documents to evidence such release. 

SECTION 13.06 Collateral Agent 
 (a)
The Collateral Agent will hold (directly or through co-trustees or agents) and, subject to the terms of the Collateral Agency Agreement, will be entitled to enforce all Liens on the Collateral created by the
Security Documents. 
 (b) Except as provided in the Collateral Agency Agreement or as directed by an Act of Parity Lien Debtholders in
accordance with the Collateral Agency Agreement, the Collateral Agent will not be obligated: 
 (1) to act upon directions
purported to be delivered to it by any Person; 
 (2) to foreclose upon or otherwise enforce any Lien; or 

(3) to take any other action whatsoever with regard to any or all of the Security Documents, the Liens created thereby or the
Collateral.

to the Trustee may on behalf of all of the Holders of the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except as provided in the Indenture)
have been cured or waived. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power.

Stock of the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.
