invest and reinvest the amounts on deposit in the Trust Accounts (other than amounts in the Cash Collateral Accounts as a result of a Non-Extension Drawing, a Downgrade Drawing or a Special Termination
Advance, which shall be governed by the foregoing proviso) in Eligible Investments in accordance with the written instructions of the Controlling Party. Unless otherwise expressly provided in this Agreement (including, without limitation, with
respect to Investment Earnings on amounts on deposit in the Cash Collateral Accounts, Section 3.05(f)), any Investment Earnings shall be deposited in the Collection Account when received by the Subordination Agent and shall be applied by the
Subordination Agent in the same manner as the other amounts on deposit in the Collection Account are to be applied. The Subordination Agent’s reasonable fees and expenses actually incurred in making such investments and any losses incurred in
such investments shall be charged against the principal amount invested. The Subordination Agent shall not be liable for any loss resulting from any investment, reinvestment or liquidation required to be made under this Agreement other than by
reason of its willful misconduct or negligence. Eligible Investments and any other investment required to be made hereunder shall be held to their maturities except that any such investment may be sold (without regard to its maturity) by the
Subordination Agent without instructions whenever such sale is necessary to make a distribution required under this Agreement. Uninvested funds held hereunder shall not earn or accrue interest. 

(c) The Subordination Agent shall possess all right, title and interest in all funds on deposit from time to time in the Trust Accounts and in
all proceeds thereof (including all income thereon, except as otherwise expressly provided herein with respect to Investment Earnings). The Trust Accounts shall be held in trust by the Subordination Agent under the sole

dominion and control of the Subordination Agent for the benefit of the applicable Trustee, the applicable Certificateholders and the applicable Liquidity Provider, as the case may be. If, at any
time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the Subordination Agent shall within 10 Business Days (or such longer period, not to exceed 30 calendar days, to which a Rating Agency may consent) establish a new
Collection Account, Special Payments Account or Cash Collateral Account, as the case may be, as an Eligible Deposit Account and shall transfer any cash and/or any investments to such new Collection Account, Special Payments Account or Cash
Collateral Account, as the case may be. So long as the Subordination Agent is an Eligible Institution, the Trust Accounts shall be maintained with it as Eligible Deposit Accounts. 

Section 2.03 Deposits to the Collection Account and Special Payments Account. (a) The Subordination Agent shall, upon receipt
thereof, deposit in the Collection Account all Scheduled Payments received by it (other than any Scheduled Payment which by the express terms hereof is to be deposited to a Cash Collateral Account).

absence of any such notice, upon receipt by the Subordination Agent of a Special Payment), the Subordination Agent shall promptly give notice thereof to each Trustee and the Liquidity Providers. The Subordination Agent shall promptly calculate the
amount of the proceeds of any redemption, purchase or prepayment of any Equipment Note or the amount of any Overdue Scheduled Payment or the proceeds of Equipment Notes or Collateral, as the case may be, comprising such Special Payment under the
applicable Indenture or Indentures and shall promptly send to each Trustee and the Liquidity Providers a Written Notice of such amount and the amount allocable to each Trust. Such Written Notice shall also set the distribution date for such Special
Payment (a “Special Distribution Date”), which shall be the Business Day which immediately follows the later to occur of (x) the 15th day after the date of such
Written Notice and (y) the date the Subordination Agent has received or expects to receive such Special Payment. Amounts on deposit in the Special Payments Account shall be distributed in accordance with Sections 2.04(b) and 2.04(c)
and Article III hereof, as applicable. 
 For the purposes of the application of any Special Payment in respect of any Equipment Note
to be distributed on any Special Distribution Date in accordance with Section 3.02 hereof, so long as no Indenture Event of Default shall have occurred and be continuing under any Indenture: 

(i) clause “second” thereof shall be deemed to read as follows: “second, accrued and unpaid Liquidity
Expenses then overdue plus an amount equal to all accrued and unpaid Liquidity Expenses not yet overdue multiplied by the Section 2.04 Fraction shall be distributed to the Liquidity Providers pro rata on the basis of the amount of the Liquidity

been converted into a Final Drawing, the outstanding amount of such Special Termination Advances, shall be distributed to the Liquidity Providers, pro rata on the basis of the amounts owed to each Liquidity Provider”; 

(iii) clause “seventh” thereof shall be deemed to read as follows: “seventh, such amount as shall be
required to pay accrued, due and unpaid interest at the Stated Interest Rate on the outstanding Pool Balance of the Class AA Certificates, together with (without duplication) any other accrued and unpaid interest at the Stated Interest Rate on
the outstanding principal amount of the Series AA Equipment Notes held in the Class AA Trust being redeemed, purchased or prepaid shall be paid to the Class AA Trustee”;

Class A Certificates, together with (without duplication) any other accrued and unpaid interest at the Stated Interest Rate on the outstanding principal amount of the Series A Equipment Notes held in the Class A Trust and being redeemed,
purchased or prepaid shall be paid to the Class A Trustee”. 
 (b) Investment of Amounts in Special Payments Account. Any
amounts on deposit in the Special Payments Account prior to the distribution thereof pursuant to Section 2.04 or 3.02 shall be invested in accordance with Section 2.02(b). Investment Earnings on such investments shall be distributed
in accordance with Article III hereof. 
 (c) Certain Payments. Except for amounts constituting Liquidity Obligations which shall
be distributed as provided in Section 3.02, the Subordination Agent will distribute promptly upon receipt thereof (i) any indemnity payment or expense reimbursement received by it from Delta in respect of any Trustee or any Liquidity
Provider (collectively, the “Payees”) and (ii) any compensation received by it from Delta under any Operative Agreement in respect of any Payee, directly to the Person entitled thereto, provided that if such Payee has
previously received from the Collection Account such payment, compensation or reimbursement, then the Subordination Agent shall deposit such amount in the Collection Account.

 Section 2.06 Controlling Party. (a) Subject to Section 8.01(b), the Trustees and the
Liquidity Providers hereby agree that, with respect to any Indenture at any given time, the Loan Trustee thereunder will be directed: (i) so long as no Indenture Event of Default has occurred and is continuing thereunder, in taking, or

 Intercreditor
Agreement (2019-1) 


  
 25 












 
the registered holder of such Equipment Notes, the Subordination Agent shall act with respect to this clause (i) in accordance with the directions of the Trustees (in the case of each such
Trustee, with respect to the Equipment Notes issued under such Indenture and held as Trust Property of such Trust) constituting, in the aggregate, directions with respect to an outstanding principal amount of such Equipment Notes that, if held by
such Trustees directly, would make such Trustees a Majority in Interest of Noteholders), and (ii) after the occurrence and during the continuance of an Indenture Event of Default thereunder, in taking, or refraining from taking, any action
under such Indenture or with respect to such Equipment Notes issued thereunder, including exercising remedies thereunder (including Accelerating the Equipment Notes issued thereunder or foreclosing the Lien created thereunder on the Aircraft

 (b) Subject to paragraph (c) below, the “Controlling Party” shall
be (i) the Class AA Trustee and (ii) upon payment of Final Distributions to the holders of Class AA Certificates, but prior to payment of Final Distributions to the holders of Class A Certificates, the Class A Trustee,
and (iii) upon payment of Final Distributions to the holders of Class AA Certificates and Class A Certificates, but, if any class or classes of Additional Certificates are outstanding, prior to payment of Final Distributions to the
holders of the most senior, in priority of payment of “Expected Distributions” under this Agreement, class of Additional Certificates, the Additional Trustee for the Additional Trust related to such most senior class of Additional
Certificates. For purposes of giving effect to the provisions of Section 2.06(a) and this Section 2.06(b), the Trustees (other than the Controlling Party) irrevocably agree (and the Certificateholders (other than the Certificateholders
represented by the Controlling Party) shall be deemed to agree by virtue of their purchase of Certificates) that the Subordination Agent, as record holder of the Equipment Notes, and subject always to the provisions of Section 2.06(a) and
Article VIII, shall exercise its voting rights in respect of the Equipment Notes so held by the Subordination Agent as directed by the Controlling Party and any vote so exercised shall be binding upon the Trustees and all Certificateholders.

 The Subordination Agent shall give Written Notice to all of the other parties to this Agreement promptly upon a change in the identity of
the Controlling Party. Each of the parties hereto agrees that it shall not exercise any of the rights of the Controlling Party at such time as it is not the Controlling Party hereunder; provided, however, that nothing herein contained
shall prevent or prohibit any Non-Controlling Party from exercising such rights as shall be specifically granted to such Non-Controlling Party hereunder and under the
other Operative Agreements.

(ii) the date on which the entire amount of any Downgrade Drawing or Non-Extension Drawing under any Liquidity Facility shall have become and remain “Applied Downgrade Advances” or “Applied

be considered Accelerated for purposes of this subclause (iii) until the expiration of the 60-Day Period or such longer period as may apply under Section 1110(a)(2)(B) or Section 1110(b) of
the Bankruptcy Code), the Liquidity Provider with the greatest amount of unreimbursed Liquidity Obligations owed to it (so long as such Liquidity Provider has not defaulted in its obligation to make any Drawing under its Liquidity Facility) shall
have the right to elect, by Written Notice to the Subordination Agent and each of the Trustees, to become the Controlling Party hereunder with respect to any Indenture at any time from and including the last day of
such 18-month period. 
 (d) [Reserved]. 

(e) The exercise of remedies by the Controlling Party under this Agreement shall be expressly limited by Sections 4.01(a)(ii)
and 4.01(a)(iii) hereof. 
 (f) The Controlling Party shall not be entitled to require or obligate any
Non-Controlling Party to provide funds necessary to exercise any right or remedy hereunder.

event within 10 days of the occurrence of a Downgrade Event with respect to it (the date of such occurrence, the “Downgrade Date”), deliver notice to the Subordination Agent and Delta of the occurrence of such Downgrade
Event and the Downgrade Date therefor. After the occurrence of a Downgrade Event with respect to any Liquidity Provider, each Liquidity Facility provided by such Liquidity Provider shall become a “Downgraded Facility” on the 35th day after the related Downgrade Date, unless, not later than such 35th day (or, if earlier, the expiration date of such Downgraded
Facility), the Rating Agency whose downgrading of such Liquidity Provider resulted in such Downgrade Event shall have provided a written confirmation to the effect that the occurrence of such Downgrade Event will not result in the downgrading,
withdrawal or suspension of the ratings then issued by such Rating Agency of the related Class of Certificates. Notwithstanding the foregoing, if at any time after the occurrence of such Downgrade Event, such Liquidity Provider notifies the
Subordination Agent in writing that no such confirmation will be provided by such Rating Agency, each Liquidity Facility provided by such Liquidity Provider shall become a Downgraded Facility as of the date of such notice to the Subordination Agent.

 (ii) If at any time any Liquidity Facility becomes a Downgraded Facility, not later than the 35th day after the related Downgrade Date (or, if earlier, the expiration date of such Downgraded Facility), the Liquidity Provider under such Downgraded Facility (at its own expense, except as provided
in the applicable Fee Letter) or Delta (at its own expense, except as provided in the applicable Fee Letter) may arrange for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility to the Subordination Agent in
accordance with Section 3.05(e). 
 (iii) If a Downgraded Facility has not been replaced by a Replacement Liquidity Facility in
accordance with Section 3.05(c)(ii), the Subordination Agent shall, on the 35th day referred to in Section 3.05(c)(ii) (or if such 35th day is not a Business Day, on the next succeeding Business Day) (or, if earlier, the expiration date of such Downgraded Facility), request a drawing in accordance with and to the extent permitted by
such Downgraded Facility (such drawing, a “Downgrade Drawing”) of the Available Amount thereunder. Amounts drawn pursuant to a Downgrade Drawing shall be maintained and invested as provided in Section 3.05(f) hereof. Subject to
Section 3.05(e)(iii), the applicable Liquidity Provider may also arrange for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility at any time after such Downgrade Drawing so long as such Downgrade Drawing has
not been reimbursed in full to such Liquidity Provider. 
 (iv) For the avoidance of doubt, the provisions of this Section 3.05(c) shall
apply to each occurrence of a Downgrade Event with respect to a Liquidity Provider, regardless of whether or not one or more Downgrade Events have occurred prior thereto and whether or not any confirmation by a Rating Agency specified in
Section 3.05(c)(i) has been obtained with respect to any prior occurrence of a Downgrade Event.

 (v) If, at any time after making a Downgrade Drawing, the applicable Liquidity Provider
satisfies the Threshold Rating and delivers written notice to such effect to the Subordination Agent and Delta, as of the second Business Day following receipt of such notice, (A) such Downgraded Facility shall cease to be a Downgraded
Facility, (B) the Subordination Agent shall withdraw the unapplied amount of such Downgrade Drawing on deposit in the applicable Cash Collateral Account and reimburse such amount to such Liquidity Provider, (C) any applied amount of such
Downgrade Drawing shall be deemed to have been converted to an Interest Drawing as of such date in accordance with the applicable Liquidity Facility, (D) the obligations of such Liquidity Provider shall be reinstated in accordance with the
applicable Liquidity Facility, and (E) the proviso in the definition of Available Amount shall no longer apply to such Downgrade Drawing. 

(d) Non-Extension Drawings. If any Liquidity Facility with respect to any Class of
Certificates is scheduled to expire on a date (the “Stated Expiration Date”) prior to the date that is 15 days after the Final Legal Distribution Date for such Class of Certificates, then the following provisions
shall apply: 
 (i) In the case of either initial Liquidity Facility or any other Liquidity Facility having extension
provisions identical to those set forth in Section 2.10 of either initial Liquidity Facility, then, if before the 60th day prior to any anniversary date of the Closing Date (such 60th day, the “Notice Date”), the Liquidity Provider shall have advised the Subordination Agent and Delta that such Liquidity Facility shall not be extended beyond the immediately
following anniversary date of the Closing Date and on or before the 25th day prior to such anniversary date such Liquidity Facility shall not have been replaced in accordance with
Section 3.05(e), the Subordination Agent shall, on such 25th day (or as soon thereafter as possible but prior to the date of expiration of the expiring Liquidity Facility (a “Non-Extended Facility”), in accordance with the terms of such Non-Extended Facility, request a drawing under such Non-Extended
Facility (such drawing, a “Non-Extension Drawing”) of the Available Amount thereunder. 

(ii) In the case of any other Liquidity Facility, no earlier than
the 60th day and no later than the 40th day prior to the then applicable Stated Expiration Date, the Subordination Agent shall
request in writing that such Liquidity Provider extend the Stated Expiration Date to the earlier of (i) the date that is 15 days after the Final Legal Distribution Date for such Class of Certificates and (ii) the date that
is the day immediately preceding the 364th day after the last day of the Consent Period (unless the obligations of such Liquidity Provider thereunder are earlier terminated in accordance with
such Liquidity Facility). Whether or not the applicable Liquidity Provider has received a request from the Subordination Agent, such Liquidity Provider shall by notice (the “Consent Notice”) to the Subordination Agent, during the
period commencing on the date that is 60 days prior to the then effective Stated Expiration Date (or if earlier, the date of such Liquidity Provider’s receipt of such request, if any, from the Subordination Agent) and ending on the
date that is 25 days prior to such Stated Expiration Date (the 

  
 Intercreditor
Agreement (2019-1)

“Consent Period”) advise the Subordination Agent whether, in its sole discretion, it agrees to so extend the Stated Expiration Date; provided, that such extension shall not be
effective with respect to such Liquidity Provider if, by notice (the “Withdrawal Notice”) to the Subordination Agent prior to the end of the Consent Period, such Liquidity Provider revokes its Consent Notice. If a Liquidity Provider
advises the Subordination Agent on or before the end of the Consent Period that such Stated Expiration Date shall not be so extended or fails to irrevocably and unconditionally advise the Subordination Agent on or before the end of the Consent
Period that such Stated Expiration Date shall be so extended or gives a Withdrawal Notice to the Subordination Agent prior to the end of the Consent Period (and, in each case, if such Liquidity Provider shall not have been replaced in accordance
with Section 3.05(e)), the Subordination Agent shall, on the date on which the Consent Period ends (or as soon as possible thereafter but prior to the Stated Expiration Date), in accordance with and to the extent permitted by the terms of the Non-Extended Facility, request a Non-Extension Drawing under such Non-Extended Facility of the Available Amount thereunder. 

(iii) Amounts drawn pursuant to a Non-Extension Drawing shall be maintained and
invested in accordance with Section 3.05(f). 
 (e) Issuance of Replacement Liquidity Facility. (i) Subject to
Section 3.05(e)(iii) and the agreements, if any, in the applicable Fee Letter, at any time, Delta may, at its option and at its own expense, with cause or without cause, arrange for a Replacement Liquidity Facility to replace any Liquidity
Facility for any Class of Certificates (including any Replacement Liquidity Facility provided pursuant to Section 3.05(e)(ii)). If such Replacement Liquidity Facility is provided at any time after a Downgrade Drawing, a Non-Extension Drawing or a Special Termination Advance has been made, all funds on deposit in the relevant Cash Collateral Account resulting from such Downgrade Drawing,
Non-Extension Drawing or Special Termination Advance will be returned to the Liquidity Provider being replaced. 

(ii) If any Liquidity Provider shall determine not to extend its Liquidity Facility in accordance with Section 3.05(d), then such
Liquidity Provider may, at its option and its own expense, arrange for a Replacement Liquidity Facility to replace such Liquidity Facility during the period no earlier than 40 days and no later than 25 days prior to the then
effective Stated Expiration Date of such Liquidity Facility. At any time after a Non-Extension Drawing has been made under any Liquidity Facility, the Liquidity Provider thereunder may, at its option and its
own expense, arrange for a Replacement Liquidity Facility to replace the Liquidity Facility under which such Non-Extension Drawing has been made. 

(iii) No Replacement Liquidity Facility arranged by Delta or a Liquidity Provider in accordance with clause (i) or (ii) above or
pursuant to Section 3.05(c), respectively, shall become effective and no such Replacement Liquidity Facility shall be deemed a “Liquidity Facility” under the Operative Agreements, unless and until (A) each of the conditions
referred to in sub-clauses (iv)(x) and (z) below shall have been satisfied, (B) if such Replacement Liquidity Facility shall materially adversely affect the rights, remedies, interests or
obligations of the Class AA Certificateholders or the Class A Certificateholders under any of the Operative Agreements, the applicable Trustee shall have consented, in writing, to the execution and issuance of such Replacement Liquidity
Facility and (C) in the case of a Replacement Liquidity Facility arranged by a Liquidity Provider under Section 3.05(e)(ii) or pursuant to Section 3.05(c), such Replacement Liquidity Facility is reasonably acceptable to Delta.

 (iv) In connection with the issuance of each Replacement Liquidity Facility, the
Subordination Agent shall (x) prior to the issuance of such Replacement Liquidity Facility, obtain written confirmation from each Rating Agency to the effect that such Replacement Liquidity Facility will not cause a reduction, withdrawal or
suspension of any rating then in effect for the related Class of Certificates by such Rating Agency (without regard to any downgrading of any rating of the Liquidity Provider being replaced pursuant to Section 3.05(c)), (y) pay all
Liquidity Obligations then owing to the replaced Liquidity Provider (which payment shall be made first from available funds in the applicable Cash Collateral Account as described in Section 3.05(f), and thereafter from any other available
source, including, without limitation, a drawing under the Replacement Liquidity Facility) and (z) cause the issuer of the Replacement Liquidity Facility to deliver the Replacement Liquidity Facility to the Subordination Agent, together with a
legal opinion opining that such Replacement Liquidity Facility is an enforceable obligation of such Replacement Liquidity Provider. 
 (v)
Upon satisfaction of the conditions set forth in clauses (iii) and (iv) of this Section 3.05(e) with respect to a Replacement Liquidity Facility, (1) the replaced Liquidity Facility shall terminate, (2) the Subordination
Agent shall, if and to the extent so requested by Delta or the Liquidity Provider being replaced, execute and deliver any certificate or other instrument required in order to terminate the replaced Liquidity Facility, shall surrender the replaced
Liquidity Facility to the Liquidity Provider being replaced and shall execute and deliver the Replacement Liquidity Facility and any associated Fee Letter, (3) each of the parties hereto shall enter into any amendments to this Agreement
necessary to give effect to (a) the replacement of the applicable Liquidity Provider with the applicable Replacement Liquidity Provider and (b) the replacement of the applicable Liquidity Facility with the applicable Replacement Liquidity
Facility, and (4) the applicable Replacement Liquidity Provider shall be deemed to be a Liquidity Provider with the rights and obligations of a Liquidity Provider hereunder and under the other Operative Agreements and such Replacement Liquidity
Facility shall be deemed to be a Liquidity Facility hereunder and under the other Operative Agreements. 
 (f) Cash Collateral Accounts;
Withdrawals; Investments. In the event the Subordination Agent shall draw all Available Amounts under the Class AA Liquidity Facility or the Class A Liquidity Facility pursuant to Section 3.05(c), 3.05(d), 3.05(i) or 3.05(k),
or in the event amounts are to be deposited in the Class AA Cash Collateral Account or the Class A Cash Collateral Account pursuant to subclause (A) or (B) of clause “fourth” of Section 3.02, amounts so drawn
or to be deposited, as the case may be, shall be deposited by the Subordination Agent in the Class AA Cash Collateral Account or the Class A Cash Collateral Account, as applicable. All amounts on deposit in each Cash Collateral Account
shall be invested and reinvested in Eligible Investments in accordance with Section 2.02(b).

 On each Interest Payment Date (or, in the case of any Special Distribution Date with respect
to the distribution of a Special Payment, on such Special Distribution Date), Investment Earnings on amounts on deposit in each Cash Collateral Account with respect to any Liquidity Facility (or in the case of any Special Distribution Date with
respect to the distribution of a Special Payment, so long as no Indenture Event of Default shall have occurred and be continuing under any Indenture, a fraction of such Investment Earnings equal to the Section 2.04 Fraction) shall be deposited
in the Collection Account (or, in the case of any Special Distribution Date with respect to the distribution of a Special Payment, the Special Payments Account) and applied on such Interest Payment Date (or Special Distribution Date, as the case may
be) in accordance with Section 3.02 or 3.03 (as applicable). The Subordination Agent shall deliver a written statement to Delta and each Liquidity Provider one day prior to each Interest Payment Date and Special Distribution Date setting
forth the aggregate amount of Investment Earnings held in the Cash Collateral Accounts as of such date. In addition, from and after the date funds are so deposited, the Subordination Agent shall make withdrawals from such accounts as follows: 

(i) on each Distribution Date, the Subordination Agent shall, to the extent it shall not have received funds to pay accrued and
unpaid interest due and owing on the Class AA Certificates (at the Stated Interest Rate for the Class AA Certificates) after giving effect to the subordination provisions of this Agreement, withdraw from the Class AA Cash Collateral
Account, and pay to the Class AA Trustee, an amount equal to the lesser of (x) an amount necessary to pay accrued and unpaid interest (at the Stated Interest Rate for the Class AA Certificates) on the Class AA Certificates and
(y) the amount on deposit in the Class AA Cash Collateral Account; 
 (ii) on each Distribution Date, the

Interest Rate for the Class A Certificates) on the Class A Certificates and (y) the amount on deposit in the Class A Cash Collateral Account; 

(iii) on each date on which the Pool Balance of the Class AA Trust shall have been reduced by payments made to the
Class AA Certificateholders pursuant to Section 3.02 hereof, the Subordination Agent shall withdraw from the Class AA Cash Collateral Account such amount as is necessary so that, after giving effect to the reduction of the Pool
Balance on such date (and any reduction in the amounts on deposit in the Class AA Cash Collateral Account resulting from a prior withdrawal of amounts on deposit in the Class AA Cash Collateral Account on such date) and any transfer of
Investment Earnings from such Cash Collateral Account to the Collection Account or the Special Payments Account on such date, an amount equal to the sum of the Required Amount (with respect to the Class AA Liquidity Facility) plus (if on a
Distribution Date not coinciding with an Interest Payment Date) Investment Earnings on deposit in such Cash Collateral Account (after giving effect to any such transfer of Investment Earnings) will remain on deposit in the Class AA Cash
Collateral Account and shall first, pay such withdrawn amount to the Class AA Liquidity Provider until the Class AA Liquidity Obligations owing to such Liquidity Provider shall have been paid in full, and second, deposit any remaining
withdrawn amount in the Collection Account;

 (iv) on each date on which the Pool Balance of the Class A Trust shall
have been reduced by payments made to the Class A Certificateholders pursuant to Section 3.02 hereof, the Subordination Agent shall withdraw from the Class A Cash Collateral Account such amount as is necessary so that, after giving
effect to the reduction of the Pool Balance on such date (and any reduction in the amounts on deposit in the Class A Cash Collateral Account resulting from a prior withdrawal of amounts on deposit in the Class A Cash Collateral Account on
such date) and any transfer of Investment Earnings from such Cash Collateral Account to the Collection Account or the Special Payments Account on such date, an amount equal to the sum of the Required Amount (with respect to the Class A
Liquidity Facility) plus (if on a Distribution Date not coinciding with an Interest Payment Date) Investment Earnings on deposit in such Cash Collateral Account (after giving effect to any such transfer of Investment Earnings) will remain on deposit
in the Class A Cash Collateral Account and shall first, pay such withdrawn amount to the Class A Liquidity Provider until the Class A Liquidity Obligations owing to such Liquidity Provider shall have been paid in full, and second,
deposit any remaining withdrawn amount in the Collection Account; 
 (v) if a Replacement Liquidity Facility for any relevant
Class of Certificates shall be delivered to the Subordination Agent following the date on which funds have been deposited into the Cash Collateral Account for such Class of Certificates, the Subordination Agent shall withdraw all amounts
remaining on deposit in such Cash Collateral Account and shall pay such amounts to the replaced Liquidity Provider, if any, until all Liquidity Obligations owed to such Person shall have been paid in full, and deposit any remaining amount in the
Collection Account; 
 (vi) if the Liquidity Provider with respect to a Downgraded Facility satisfies the Threshold Rating
and delivers written notice to such effect to the Subordination Agent and Delta, on the second Business Day following receipt of such notice, the Subordination Agent shall withdraw all amounts remaining on deposit in the applicable Cash Collateral
Account constituting the unapplied amount of any Downgrade Drawing and shall pay such amounts to such Liquidity Provider and the obligations of such Liquidity Provider shall be reinstated in accordance with the applicable Liquidity Facility; and

 (vii) following (x) the payment of Final Distributions or (y) the Final Legal Distribution Date with respect to
any Class of Certificates covered by a Liquidity Facility, on the date on which the Subordination Agent shall have been notified by the Liquidity Provider for such Class of Certificates that the Liquidity Obligations owed to such Liquidity
Provider have been paid in full, or, if earlier, the first Business Day after such Final Legal Distribution Date, the Subordination Agent shall withdraw all amounts on deposit in the Cash Collateral Account in respect of such Class of
Certificates, if any, and shall deposit such amounts in the Collection Account.

 (g) Reinstatement. With respect to any Interest Drawing under the Liquidity Facility
for any relevant Trust, upon the reimbursement of the applicable Liquidity Provider for all or any part of the amount of such Interest Drawing, together with any accrued interest thereon, the Available Amount of such Liquidity Facility shall be
reinstated by an amount equal to the amount of such Interest Drawing so reimbursed to the applicable Liquidity Provider but not to exceed the Stated Amount for such Liquidity Facility; provided, however, that the Available Amount of
such Liquidity Facility shall not be so reinstated in part or in full pursuant to the foregoing provisions of this Section 3.05(g) at any time if (x) both a Performing Note Deficiency exists and a Liquidity Event of Default shall have
occurred and be continuing with respect to the relevant Liquidity Facility or (y) a Final Drawing, Downgrade Drawing, Non-Extension Drawing or Special Termination Advance shall have occurred with respect
to such Liquidity Facility or an Interest Drawing shall have been converted into a Final Drawing. Notwithstanding anything to the contrary, in the event that, with respect to any particular Liquidity Facility, (i) funds are withdrawn from the
related Cash Collateral Account pursuant to clause (i) or (ii) of Section 3.05(f) or (ii) such Liquidity Facility shall become a Downgraded Facility or a Non-Extended Facility at a time
when unreimbursed Interest Drawings under such Liquidity Facility have reduced the Available Amount thereunder to zero, then funds received by the Subordination Agent at any time, other than (x) any time when both a Performing Note Deficiency
exists and a Liquidity Event of Default shall have occurred and be continuing with respect to such Liquidity Facility or (y) any time after a Final Drawing shall have occurred with respect to such Liquidity Facility or an Interest Drawing for
such Liquidity Facility shall have been converted into a Final Drawing, shall be deposited in such Cash Collateral Account as and to the extent provided in clause “fourth” of Section 3.02 and applied in accordance with
Section 3.05(f). 
 (h) Reimbursement. The amount of each drawing under the Liquidity Facilities shall be due and payable,
together with interest thereon, on the dates and at the rates, respectively, provided in the Liquidity Facilities. 
 (i) Final
Drawing. Upon receipt from a Liquidity Provider of a Termination Notice with respect to its applicable Liquidity Facility, the Subordination Agent shall, not later than the date specified in such Termination Notice, in accordance with the terms
of such Liquidity Facility, request a drawing under such Liquidity Facility of the Available Amount thereunder (a “Final Drawing”). Amounts drawn pursuant to a Final Drawing shall be maintained and invested in accordance with
Section 3.05(f). 
 (j) Adjustments of Stated Amount. Promptly following each date on which the Required Amount of the Liquidity
Facility for a relevant Class of Certificates is reduced as a result of a reduction in the Pool Balance with respect to such Certificates or otherwise, the Subordination Agent shall, if any such Liquidity Facility provides for reductions of the
Stated Amount of such Liquidity Facility and if such reductions are not automatic, request such Liquidity Provider for such Class of Certificates to reduce such Stated Amount to an amount equal to the Required Amount with respect to such
Liquidity Facility (as calculated by the Subordination Agent after giving effect to such payment). Each such request shall be made in accordance with the provisions of the applicable Liquidity Facility.

 (k) Special Termination Advance. Upon receipt from a Liquidity Provider of a Special
Termination Notice with respect to any Liquidity Facility, the Subordination Agent shall, not later than the date specified in such Special Termination Notice, in accordance with the terms of such Liquidity Facility, request a Special Termination

(m) Assignment of Liquidity Facility. The Subordination Agent agrees not to consent to the assignment by any Liquidity Provider of any
of its rights or obligations under any Liquidity Facility or any interest therein unless (i) Delta shall have consented to such assignment and (ii) each Rating Agency shall have provided a Ratings Confirmation with respect to each
Class of Certificates then rated by such Rating Agency in connection with such assignment; provided, that the Subordination Agent shall consent to such assignment if the conditions in the foregoing clauses (i) and (ii) are
satisfied, and the foregoing is not intended to and shall not be construed to limit the rights of any initial Liquidity Provider under Section 3.05(e)(ii). 

ARTICLE IV 
 EXERCISE OF
REMEDIES 
 Section 4.01 Directions from the Controlling Party. (a) (i) Following the occurrence and during the
continuation of an Indenture Event of Default under any Indenture, the Controlling Party shall direct the Subordination Agent, as the holder of the Equipment Notes issued under such Indenture, which in turn shall direct the Loan Trustee under such
Indenture, in the exercise of remedies available to the holders of such Equipment Notes, including, without limitation, the ability to vote all such Equipment Notes held by the Subordination Agent in favor of Accelerating such Equipment Notes in
accordance with the provisions of such Indenture. Subject to Section 4.01(a)(iii), if the Equipment Notes issued pursuant to any Indenture have been Accelerated following an Indenture Event of Default with respect thereto, the Controlling Party
may direct the Subordination Agent to sell, assign, contract to sell or otherwise dispose of and deliver all (but not less than all) of such Equipment Notes to any Person at public or private sale, at any location at the option of the Controlling
Party, all upon such terms and conditions as the Controlling Party may reasonably deem advisable and in accordance with applicable law. 

(ii) Following the occurrence and during the continuation of an Indenture Event of Default under any Indenture, in the exercise of remedies
pursuant to such Indenture, the Loan Trustee under such Indenture may be directed to lease the related Aircraft to any Person (including Delta) so long as the Loan Trustee in doing so acts in a “commercially reasonable” manner within the
meaning of Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction (including Sections 9-610 and 9-627 thereof). 

  
 Intercreditor
Agreement (2019-1) 


  
 40 












 (iii) Notwithstanding the foregoing, so long as any Certificates remain Outstanding, during
the period ending on the date which is nine months after the earlier of (x) the Acceleration of the Equipment Notes issued pursuant to any Indenture or (y) the occurrence of a Delta Bankruptcy Event, without the consent of each Trustee
(other than the Trustee of any Trust all of the Certificates of which are held or beneficially owned by Delta and/or its Affiliates), no Aircraft subject to the Lien of such Indenture or such Equipment Notes may be sold if the net proceeds from such
sale would be less than the Minimum Sale Price for such Aircraft or such Equipment Notes. 
 (iv) Upon the occurrence and continuation of an
Indenture Event of Default under any Indenture, the Subordination Agent will obtain a desktop appraisal from each of the three Appraisers selected by the Controlling Party setting forth the current market value, current lease rate and distressed
value (in each case, as defined by the International Society of Transport Aircraft Trading or any successor organization) of the Aircraft subject to such Indenture (each such appraisal, an “Appraisal” and the current market value
appraisals being referred to herein as the “Post-Default Appraisals”). For so long as any Indenture Event of Default shall be continuing under any Indenture, and without limiting the right of the Controlling Party to request more
frequent Appraisals, the Subordination Agent will obtain updated Appraisals on the date that is 364 days from the date of the most recent Appraisal (or if a Delta Bankruptcy Event shall have occurred and is continuing, on the date that
is 180 days from the date of the most recent Appraisal) and shall (acting on behalf of each Trustee) post such Appraisals on DTC’s Internet bulletin board or make such other commercially reasonable efforts as the Subordination Agent
may deem appropriate to make such Appraisals available to all Certificateholders. 
 (b) Following the occurrence and during the continuance
of an Indenture Event of Default under any Indenture, the Controlling Party shall take such actions as it may reasonably deem most effectual to complete the sale or other disposition of the relevant Aircraft or Equipment Notes. In addition, in lieu
of any sale, assignment, contract to sell or other disposition, the Controlling Party may maintain or cause the Subordination Agent to maintain possession of such Equipment Notes and continue to apply monies received in respect of such Equipment
Notes in accordance with Article III hereof. In addition, in lieu of such sale, assignment, contract to sell or other disposition, or in lieu of such maintenance of possession, the Controlling Party may direct the Subordination Agent to,
subject to the terms and conditions of the related Indenture, instruct the Loan Trustee under such Indenture to foreclose on the Lien on the related Aircraft or to take any other remedial action permitted under such Indenture or under any applicable
law. 
 (c) If following a Delta Bankruptcy Event and during the pendency thereof, the Controlling Party receives a proposal from or on
behalf of Delta to restructure the financing of any one or more of the Aircraft, the Controlling Party shall promptly thereafter give the Subordination Agent, each Trustee and each Liquidity Provider that has not made a Final Drawing notice of the
material economic terms and conditions of such restructuring proposal whereupon the Subordination Agent acting on behalf of each Trustee shall post such terms and conditions of such restructuring proposal on DTC’s Internet bulletin board or
make such other commercially reasonable efforts as the Subordination Agent may deem appropriate to make such 

  
 Intercreditor

 41 












 
terms and conditions available to all Certificateholders. Thereafter, neither the Subordination Agent nor any Trustee, whether acting on instructions of the Controlling Party or otherwise, may,
without the consent of each Trustee and each Liquidity Provider that has not made a Final Drawing, enter into any term sheet, stipulation or other agreement (a “Restructuring Arrangement”) (whether in the form of an adequate
protection stipulation, an extension under Section 1110(b) of the Bankruptcy Code or otherwise) to effect any such restructuring proposal with or on behalf of Delta unless and until the material economic terms and conditions of such
restructuring proposal shall have been made available to all Certificateholders and each Liquidity Provider that has not made a Final Drawing for a period of not less than 15 days (except that such requirement shall not apply to any such
term sheet, stipulation or other agreement that is to be effective on or as of any date occurring during the 60-Day Period and that is initially effective for a period not exceeding three months from the
expiry of the 60-Day Period (an “Interim Restructuring Arrangement”)). The foregoing provisions of this Section 4.01(c): (i) shall not apply to any extension of a Restructuring
Arrangement with respect to which such provisions have been complied with in connection with the original entry thereof if the possibility of such extension has been disclosed in satisfaction of the notification requirements of such provisions and
such extension shall not amend or modify any of the other terms and conditions of such Restructuring Arrangement and (ii) shall apply to the initial extension of an Interim Restructuring Arrangement beyond the three months following the expiry
of the 60-Day Period but not to any subsequent extension of such Interim Restructuring Arrangement, if the possibility of such subsequent extension has been disclosed in satisfaction of the notification
requirements of such provisions and such subsequent extension shall not amend or modify any of the other terms and conditions of such Interim Restructuring Arrangement. In the event that any Certificateholder gives irrevocable notice of the exercise
of its right to purchase all (but not less than all) of the Class of Certificates represented by the then Controlling Party pursuant to the applicable Trust Agreement, prior to the expiry of
the 15-day notice period specified above, such Controlling Party may not direct the Subordination Agent or any Trustee to enter into any such restructuring proposal with respect to any of the Aircraft,
unless and until such Certificateholder shall fail to purchase such Class of Certificates on the date that it is required to make such purchase. 

Section 4.02 Remedies Cumulative. To the extent permitted by applicable law, each and every right, power and remedy given to the
Trustees, the Liquidity Providers, the Controlling Party or the Subordination Agent specifically or otherwise in this Agreement shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or
hereafter existing at law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may, subject always to the terms and conditions hereof, be exercised from time to time and as
often and in such order as may be deemed expedient by any Trustee, any Liquidity Provider, the Controlling Party or the Subordination Agent, as appropriate, and the exercise or the beginning of the exercise of any right, power or remedy shall not be
construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by any Trustee, any Liquidity Provider, the Controlling Party or the Subordination Agent in the exercise of any
right, remedy or power or in the pursuit of any remedy shall, to the extent permitted by applicable law, impair any such right, power or remedy or be construed to be a waiver of any default or to be an acquiescence therein.

 Section 4.03 Discontinuance of Proceedings. In case any party to this Agreement
(including the Controlling Party in such capacity) shall have instituted any Proceeding to enforce any right, power or remedy under this Agreement by foreclosure, entry or otherwise, and such Proceeding shall have been discontinued or abandoned for
any reason or shall have been determined adversely to the Person instituting such Proceeding, then and in every such case each such party shall, subject to any determination in such Proceeding, be restored to its former position and rights
hereunder, and all rights, remedies and powers of such party shall continue as if no such Proceeding had been instituted. 

Section 4.04 Right of Certificateholders and the Liquidity Providers to Receive Payments Not to Be Impaired. Anything in this
Agreement to the contrary notwithstanding but subject to each Trust Agreement, the right of any Certificateholder or any Liquidity Provider, respectively, to receive payments hereunder (including, without limitation, pursuant to Section 3.02)
when due, or to institute suit for the enforcement of any such payment on or after the applicable Distribution Date, shall not be impaired or affected without the consent of such Certificateholder or such Liquidity Provider, respectively. 

ARTICLE V 
 DUTIES OF
THE SUBORDINATION AGENT; AGREEMENTS OF TRUSTEES, ETC. 
 Section 5.01 Notice of Indenture Event of Default or Triggering
Event. (a) If the Subordination Agent shall have knowledge of an Indenture Event of Default or a Triggering Event, the Subordination Agent shall promptly give notice thereof to the Rating Agencies, Delta, the Liquidity Providers and the

less than a majority in interest in such Trust or as otherwise authorized pursuant to the relevant Trust Agreement (including, without limitation, without the consent of the Certificateholders to
the extent permitted thereby, Section 9.01 thereof)), the Subordination Agent and each Liquidity Provider; provided, however, that this Agreement may be supplemented, amended or modified by a written agreement of Delta and the
Subordination Agent without the consent of any Trustee or any Liquidity Provider (i) in order to cure any ambiguity or omission or to correct any mistake, (ii) in order to make any other provision in regard to matters or questions arising
hereunder that will not materially adversely affect the interests of any Trustee or the holders of the related Class of Certificates or any Liquidity Provider (provided, that the consent of any Trustee or Liquidity Provider shall be
required only if such Trustee’s interests (or the interests of the holders of the related Class of Certificates) or such Liquidity Provider’s interests, respectively, will be materially adversely affected) or (iii) if such
supplement, amendment or modification is in accordance with Section 8.01(c) or 8.01(d); provided further, however, that, if such supplement, amendment or modification (x) would directly or indirectly amend, modify
or supersede, or otherwise conflict with, Section 2.02(b), 3.05(c), 3.05(e), 3.05(f), 3.05(m), 4.01(a)(ii) or 4.01(c), this proviso of Section 8.01(a), the last sentence of Section 8.01(a) or Section 8.01(c), 8.01(d)

such supplement, amendment or modification shall not be effective without the additional written consent of Delta. Notwithstanding the foregoing, without the consent of each Certificateholder affected thereby and each Liquidity Provider, no
supplement, amendment or modification of this Agreement may (i) reduce the percentage of the interest in any Trust evidenced by the Certificates issued by such Trust necessary to consent to modify or amend any provision of this Agreement or to
waive compliance therewith or (ii) except as provided in the last sentence of this Section 8.01(a) or Section 8.01(c) or Section 8.01(d), modify Section 2.04, 3.02 or 3.03 hereof relating to the distribution of monies
received by the Subordination Agent hereunder from the Equipment Notes or pursuant to the Liquidity Facilities. Nothing contained in this Section 8.01(a) shall require the consent of a Trustee at any time following the payment of Final
Distributions with respect to the related Class of Certificates. If the Replacement Liquidity Facility for any Liquidity Facility is to be comprised of more than one instrument as contemplated by the definition of the term “Replacement
Liquidity Facility”, then each party hereto agrees to amend this Agreement and the other Operative Agreements to incorporate appropriate mechanics for multiple instruments for such Replacement Liquidity Facility for a single Trust (including
without limitation clauses (i) and (ii) of Section 2.04(a) and clauses “first” through “fifth” of Section 3.02, in each case, with respect to the Replacement Liquidity Provider of such Replacement Liquidity
Facility).

giving of notice or its consent to any amendment, supplement, modification, approval, consent or waiver under such Equipment Notes, the Indenture pursuant to which such Equipment Notes were issued, the related Participation Agreement or other
related document, (i) if no Indenture Event of Default shall have occurred

such Equipment Notes and shall vote or consent in accordance with the directions of such Trustee and (ii) if any Indenture Event of Default shall have occurred and be continuing with respect to such Indenture, the Subordination Agent will
exercise its voting rights as directed by the Controlling Party, subject to Sections 4.01 and 4.04. Notwithstanding the foregoing, without the consent of each Liquidity Provider and each affected Certificateholder holding Certificates
representing a Fractional Undivided Interest in the Equipment Notes under the applicable Indenture held by the Subordination Agent, no such amendment, supplement, modification, approval, consent or waiver shall (i) reduce the principal amount
of, Premium, if any, or interest on, any such Equipment Note under such Indenture; (ii) change the date on which any principal amount of, Premium, if any, or interest on any such Equipment Note under such Indenture, is due or payable;
(iii) create any Lien with respect to the Collateral subject to such Indenture prior to or pari passu with the Lien thereon under such Indenture except such as are permitted by such Indenture; provided that, without the consent of
each Certificateholder, no such amendment, supplement, modification, approval, consent or waiver shall modify Section 3.03 or Section 9.02(a)(3) of such Indenture or deprive any Certificateholder of the benefit of the Lien of such
Indenture on such Collateral, except as provided in connection with the exercise of remedies under Article IV of such Indenture or as otherwise permitted by such Indenture; (iii) reduce the percentage of the outstanding principal amount of
the Equipment Notes under such Indenture the consent of whose holders is required for any supplemental agreement, or the consent of whose holders is required for any waiver of compliance with certain provisions of such Indenture or of certain
defaults thereunder or their consequences provided for in such Indenture; or (v) make any change in Section 4.05 or Section 9.02 of such Indenture, except to provide that certain other provisions of such Indenture cannot be modified
or waived without the consent of each holder of an Equipment Note under such Indenture affected thereby. 
 (c) If (x) the Series
A Equipment Notes (or any series of Additional Equipment Notes), with respect to all of the Aircraft for which Series A Equipment Notes (or such series of Additional Equipment Notes) are at the time outstanding, are redeemed and new Equipment Notes
of a corresponding series are to be issued with respect to any or all of the Aircraft under the applicable Indentures or (y) at any time following the payment in full of the Series A Equipment Notes (or any series of Additional Equipment Notes)
with respect to all of the Aircraft for which Series A Equipment Notes (or such series of Additional Equipment Notes) are at the time outstanding and new Equipment Notes of a corresponding series are to be issued with respect to any or all of the
Aircraft under the applicable Indentures, in each case in accordance with the terms of Section 2.02 of each such Indenture, such series of new Equipment Notes in each case (the “Refinancing Equipment Notes”) shall be issued to
a new pass through trust (a “Refinancing Trust”) that issues a class of pass through certificates (the “Refinancing Certificates”) to certificateholders (each, a “Refinancing Certificateholder”)
pursuant to a pass through trust agreement (a “Refinancing Trust Agreement”) with a trustee (a “Refinancing Trustee”). A Refinancing Trust, a Refinancing Trustee and the Refinancing Certificates shall be subject to
all of the provisions of this Agreement in the same manner as the Trust, the Trustee and the Certificates of the Class corresponding to the series of the refinanced Equipment Notes, including, the subordination of the Refinancing Certificates

any other class of Additional Certificates that rank senior, in priority of payment of “Expected Distributions” under this Agreement, to such Refinancing Certificates. Such issuance of Refinancing Equipment Notes and Refinancing
Certificates and the amendment of this Agreement as provided below shall require Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies and shall not materially adversely affect any of the Trustees in

(ii) the definitions of “Certificate”, “Class”, “Class A Certificates”, “Final Legal

the Refinancing Certificates and the Refinancing Equipment Notes); 
 (iii) the Refinancing Certificates may have the benefit
of credit support similar to the Liquidity Facilities or different therefrom and claims for fees, interest, expenses, reimbursement of advances and other obligations arising from such credit support (A) in the case of any Refinancing
Certificates issued in respect of the Class A Certificates, may rank pari passu with similar claims in respect of the Liquidity Facilities, (B) in the case of any Refinancing Certificates issued in respect of any class of Additional
Certificates generally subordinated to the Class AA Certificates and Class A Certificates (but not to any other class of Additional Certificates), may rank pari passu with similar claims in respect of the Class AA Liquidity
Facility and the Class A Liquidity Facility, and (C) in the case of any Refinancing Certificates issued in respect of any class of Additional Certificates to which clause (B) is not applicable, shall be subordinated to the

 (v) the scheduled payment dates on the Refinancing Equipment Notes shall be
the Regular Distribution Dates. 
 The issuance of the Refinancing Certificates in compliance with all of the foregoing terms in
clauses (i) to (v) of this Section 8.01(c) shall be deemed to not materially adversely affect any of the Trustee’s rights and obligations and shall not require the consent of any of the Trustees or the holders of any
Class of Certificates. Each of the Liquidity Providers hereby agrees and confirms that it shall be deemed to consent to any issuance and amendment in accordance with this Section 8.01(c) (without prejudice to the consent rights of the
Liquidity Providers described in the proviso to clause (iii) thereof) and that any such issuance and amendment shall not affect any of its respective obligations under the applicable Liquidity Facility, provided that a condition to the
issuance of any Refinancing Certificates issued in respect of a Class of Certificates with a Liquidity Facility shall be the payment in full of all amounts owed to the Liquidity Provider under such Liquidity Facility and the termination of such
Liquidity Facility upon the issuance of such Refinancing Certificates. The Subordination Agent shall deliver to each Trustee and each Liquidity Provider (other than the Liquidity Provider of such terminated Liquidity Facility) a copy of the
amendments made to this Agreement and all opinions, certificates and other documents delivered in connection with the issuance of any Refinancing Certificates. 

(d) Pursuant to the terms of Section 2.02 of each applicable Indenture, one or more additional series of Equipment Notes (the
“Additional Equipment Notes”), which shall be subordinated in right of payment to the Series AA Equipment Notes, the Series A Equipment Notes and, if applicable, one or more series of Additional Equipment Notes under such Indenture,
may be issued at any time and from time to time with respect to any or all of the Aircraft. If any series of Additional Equipment Notes are issued under any Indenture, each such series of Additional Equipment Notes shall be issued to a new pass
through trust (an “Additional Trust”) that issues a class of pass through certificates (the “Additional Certificates”) to certificateholders (each, an “Additional Certificateholder”) pursuant to a
pass through trust agreement (an “Additional Trust Agreement”) with a trustee (an “Additional Trustee”). In such case, this Agreement, including without limitation Sections 2.04, 3.01 and 3.02 hereof,
shall be amended by written agreement of Delta and the Subordination Agent to provide for the subordination of such class of Additional Certificates to, and to provide for distributions on the Additional Certificates after payment of, the
Administration Expenses, the Liquidity Obligations, the Class AA Certificates, the Class A Certificates and, if applicable, any other Additional Certificates that rank senior, in priority of payment of “Expected Distributions”
under this Agreement, to such Additional Certificates (subject to clause (iii) below). Such issuance, and the amendment of this Agreement as provided below shall require Ratings Confirmation with respect to each Class of Certificates then
rated by the Rating Agencies and shall not materially adversely affect any of the Trustees in their individual capacities or any of the Liquidity Providers. This Agreement shall be amended by written agreement of Delta and the Subordination Agent to
give effect to the issuance of any Additional Certificates subject to the following terms and conditions: 
 (i) the
Additional Trustee shall be added as a party to this Agreement;

“Equipment Notes”, “Final Legal Distribution Date”, “Trust”, “Trust Agreement”, and “Controlling Party” (and such other applicable definitions) shall be revised, as appropriate, to reflect the
issuance of the Additional Certificates (and the subordination thereof); 
 (iii) Section 3.02 may be revised, with
respect to any class of Additional Certificates, to provide for the distribution of “Adjusted Interest” for such class of Additional Certificates (calculated in a manner substantially similar to the calculation of Class A Adjusted
Interest) after the Class A Adjusted Interest (and, if applicable, after any “Adjusted Interest” for any Additional Certificates that rank senior, in priority of payment of “Expected Distributions” under this Agreement, to
such Additional Certificates) but before Expected Distributions on the Class AA Certificates; 
 (iv) the Additional
Certificates may have the benefit of credit support similar to the Liquidity Facilities or different therefrom, provided that (A) claims for fees, interest, expenses, reimbursement of advances and other obligations arising from such credit
support (1) may, in the case of any class of Additional Certificates generally subordinated to the Class AA Certificates and the Class A Certificates (but not any other class of Additional Certificates), rank pari passu with
similar claims in respect of the Class AA Liquidity Facility and the Class A Liquidity Facility so long as the prior written consent of the Class AA Liquidity Provider and the Class A Liquidity Provider shall have been obtained
or (2) shall, in the case of any class of Additional Certificates to which clause (1) is not applicable, be subordinated to the Administration Expenses and the Liquidity Obligations relating to each of the Class AA Certificates,
Class A Certificates and any more senior class of Additional Certificates, and (B) Ratings Confirmation with respect to each Class of Certificates then rated by the Rating Agencies shall have been obtained; 

(v) the Additional Certificates may be rated by the Rating Agencies; 

(vi) the Additional Certificates cannot be issued to Delta but may be issued to any of Delta’s Affiliates so long as such
Affiliate shall have bankruptcy remote and special purpose provisions in its certificate of incorporation or other organizational documents and any subsequent transfer of such Additional Certificates from such Affiliate to any other Affiliate of
Delta shall be similarly restricted; and 
 (vii) the scheduled payment dates on such series of Additional Equipment Notes
shall fall on a Regular Distribution Date. 
 The issuance of the Additional Certificates in compliance with all of the foregoing terms in
clauses (i) to (vii) of this Section 8.01(d) shall be deemed to not materially adversely affect any of the Trustee’s rights and obligations and shall not require the consent of any of the Trustees or the holders of any
Class of Certificates. Each of the Liquidity Providers hereby agrees and confirms that it shall be deemed to consent to any issuance and amendment in accordance with this Section 8.01(d) (without prejudice to the consent right of the
Liquidity Providers described in clause (iv)(1) thereof) and that any such issuance and amendment shall

not affect any of its respective obligations under the applicable Liquidity Facility. The Subordination Agent shall deliver to each Trustee and each Liquidity Provider a copy of the amendments
made to this Agreement and all opinions, certificates and other documents delivered in connection with the issuance of any Additional Certificates. 

Section 8.02 Subordination Agent Protected. If, in the reasonable opinion of the institution acting as the Subordination Agent
hereunder, any document required to be executed by it pursuant to the terms of Section 8.01 adversely affects any right, duty, immunity or indemnity with respect to such institution under this Agreement or any Liquidity Facility, the
Subordination Agent may in its discretion decline to execute such document. 
 Section 8.03 Effect of Supplemental Agreements.
Upon the execution of any amendment, consent or supplement hereto pursuant to the provisions hereof, this Agreement shall be and shall be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Agreement of the parties hereto and beneficiaries hereof shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms
and conditions of any such supplemental agreement shall be and be deemed to be part of the terms and conditions of this Agreement for any and all purposes. In executing or accepting any supplemental agreement permitted by this Article VIII, the
Subordination Agent shall be entitled to receive, and shall be fully protected in relying upon, an opinion of counsel stating that the execution of such supplemental agreement is authorized or permitted by this Agreement. 

Section 8.04 Notice to Rating Agencies. Promptly following its receipt of each amendment, consent, modification, supplement or

 Section 9.09 Subordination. (a) As between the Liquidity Providers (and any
additional liquidity providers in respect of any class of Refinancing Certificates or any Additional Certificates), on the one hand, and the Trustees (and any Refinancing Trustees or any Additional Trustees) and the Certificateholders (and any
Refinancing Certificateholders or any Additional Certificateholders), on the other hand, and as among the Trustees (and any Refinancing Trustees or any Additional Trustee) and the related Certificateholders (and any Refinancing Certificateholders or
any Additional Certificateholders) this Agreement shall be a subordination agreement for purposes of Section 510 of the Bankruptcy Code. 

(b) Notwithstanding the provisions of this Agreement, if prior to the payment in full to the Liquidity Providers of all Liquidity Obligations
then due and payable any party hereto shall have received any payment or distribution in respect of Equipment Notes or any other amount under the Indentures or other Operative Agreements which, had the subordination provisions of this Agreement been
properly applied to such payment, distribution or other amount, would not have been distributed to such Person, then such payment, distribution or other amount shall be received and held in trust by such Person and paid over or delivered to the
Subordination Agent for application as provided herein. 
 (c) If any Trustee, any Liquidity Provider or the Subordination Agent receives any
payment in respect of any obligations owing or amounts distributable hereunder (or, in the case of the Liquidity Providers, in respect of the Liquidity Obligations), which is subsequently invalidated, declared preferential, set aside and/or required
to be repaid to a trustee, receiver or other party, then, to the extent of such payment, such obligations or amounts (or, in the case of the Liquidity Providers, such Liquidity Obligations) intended to be satisfied shall be revived and continue in
full force and effect as if such payment had not been received. 
 (d) The Trustees (on behalf of themselves and the holders of
Certificates), the Liquidity Providers and the Subordination Agent expressly confirm and agree that the payment priorities and subordination specified in Articles II and III shall apply in all circumstances, notwithstanding (x) the fact that
the obligations owed to the Trustees are secured by certain assets and the Liquidity Obligations may not be so secured or (y) the occurrence of a Delta Bankruptcy Event or any similar event or occurrence relating to any other Person (it being
expressly agreed that the payment priorities and subordination specified in Articles II and III shall apply whether or not a claim for post-petition or post-filing interest is allowed in the proceedings resulting from such Delta Bankruptcy Event or
other event or occurrence). The Trustees expressly agree (on behalf of themselves and the holders of Certificates) not to assert priority over the holders of Liquidity Obligations (except as specifically set forth in Section 3.02) due to their
status as secured creditors in any bankruptcy, insolvency or other legal proceeding. 
 (e) Each of the Trustees (on behalf of themselves and
the holders of Certificates), the Liquidity Providers and the Subordination Agent may take any of the following actions without impairing its rights under this Agreement: 

(i) obtain a Lien on any property to secure any amounts owing to it hereunder, including, in the case of the Liquidity
Providers, the Liquidity Obligations; 

  
 Intercreditor
Agreement (2019-1) 


  
 58 












 (ii) obtain the primary or secondary obligation of any other obligor with
respect to any amounts owing to it hereunder, including, in the case of the Liquidity Providers, any of the Liquidity Obligations; 

(iii) renew, extend, increase, alter or exchange any amounts owing to it hereunder, including, in the case of the Liquidity
Providers, any of the Liquidity Obligations, or release or compromise any obligation of any obligor with respect thereto; 

(iv) refrain from exercising any right or remedy, or delay in exercising any right or remedy, which it may have; or 

(v) take any other action which might discharge a subordinated party or a surety under applicable law; 

provided, however, that the taking of any such actions by any of the Trustees, the Liquidity Providers or the Subordination Agent shall not
prejudice the rights or adversely affect the obligations of any other party under this Agreement. 
 Section 9.10 Governing Law.
THIS AGREEMENT HAS BEEN DELIVERED IN THE STATE OF NEW YORK AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. 

Section 9.11 Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto, to the
extent it may do so under applicable law, for purposes hereof and of all other Operative Agreements hereby (i) irrevocably submits itself to the non-exclusive jurisdiction of the courts of the State of
New York sitting in the City of New York and to the non-exclusive jurisdiction of the United States District Court for the Southern District of New York, for the purposes of any suit, action or other
proceeding arising out of this Agreement, the subject matter hereof or any of the transactions contemplated hereby brought by any party or parties hereto or thereto, or their successors or permitted assigns, (ii) waives, and agrees not to
assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this
Agreement or the subject matter hereof or any of the transactions contemplated hereby may not be enforced in or by such courts, and (iii) agrees that nothing herein shall affect the right to effect service of process in any other manner
permitted by law or shall limit the right to sue in any other jurisdiction. 
 (b) EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including,
without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each of the parties warrants and represents that it has reviewed this waiver with its legal


  
 Intercreditor
Agreement (2019-1) 


  
 59 












 
counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. TO THE EXTENT PERMITTED BY APPLICABLE LAW, THIS WAIVER IS
IRREVOCABLE AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT. 

(c) To the extent that any Liquidity Provider or any of its properties has or may hereafter acquire any right of immunity, whether
characterized as sovereign immunity or otherwise, and whether under the United States Foreign Sovereign Immunities Act of 1976 (or any successor legislation) or otherwise, from any legal proceedings, whether in the United States or elsewhere,
to enforce or collect upon this Agreement, including, without limitation, immunity from suit or service of process, immunity from jurisdiction or judgment of any court or tribunal or execution of a judgment, or immunity of any of its property from
attachment prior to any entry of judgment, or from attachment in aid of execution upon a judgment, each of the Class AA Liquidity Provider and the Class A Liquidity Provider, hereby irrevocably and expressly waives any such immunity, and
agrees not to assert any such right or claim in any such proceeding, whether in the United States or elsewhere. 
 Section 9.12 Non-Petition. Each Liquidity Provider covenants that until one year and one day after the Equipment Notes have been paid in full, it shall not acquiesce, petition or otherwise invoke or cause or join in invoking
or causing any Trust or any other Person to invoke the process of any governmental authority for the purpose of commencing or sustaining a case (whether voluntary or not) against such Trust under any bankruptcy, insolvency or similar law or
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of such Trust or any substantial part of its property or ordering the winding up or liquidation of the affairs of such Trust. 

Section 9.13 U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot
Act, the Subordination Agent, like all financial institutions, in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a
relationship or opens an account with the Subordination Agent. Each party to this Agreement agrees for itself that it will provide the Subordination Agent with such information relating to such party as it may reasonably request in order for the
Subordination Agent to satisfy the requirements of the U.S.A. Patriot Act.
