Amendment No. 1 to Executive Employment Agreement

 Exhibit 10.1 

AMENDMENT NO. 1 TO 

EXECUTIVE EMPLOYMENT AGREEMENT 

This Amendment No. 1 (“Amendment No. 1”) to that certain Executive Employment Agreement dated May 21, 2007 (the
“Agreement”) by and among EnteroMedics Inc. (“Company”), a Delaware corporation with its principal place of business at 2800 Patton Road, St. Paul, Minnesota 55113, and Greg S. Lea (“Employee”), a Minnesota resident,
whose address is                     . Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the
Agreement. 
 WHEREAS, pursuant to Section 7.8 of the Agreement, the parties desire to amend certain sections of the
Agreement to improve certain terms and conditions of his Employment, and 
 WHEREAS, in accordance with Section 7.8 of the
Agreement, is executed by the Employee and a member of the Company’s Board of Directors. 
 NOW, THEREFORE, in
consideration of the foregoing, and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the Company and the Employee agree to and hereby amend the terms of the Agreement as follows: 

1. Section 3.2.3 of the Agreement is deleted in its entirety, and the following is substituted in its place: 

“3.2.3 Payment of Severance for Termination By Company Without Cause or By Employee for Good Reason. In the event that
Employee’s employment is terminated prior to the expiration of the Term pursuant to subsection 3.1.6 (By Company Without Cause) or 3.1.7 (By Employee for Good Reason) and provided Employee has executed a written release to Company in
substantially the same form attached hereto as Exhibit A and the rescission period specified therein has expired, Company shall, subject to any payment delay required by Section 3.2.5, also continue to pay, as severance pay, Employee’s
Base Salary at the rate in effect on the Separation Date, for a period of twelve (12) months following the Separation Date. Such payments will be at usual and customary pay intervals of Employer and will be subject to all appropriate deductions
and withholdings. 
 Additionally, pursuant to the terms and conditions set forth in Employee’s applicable Stock Option
Agreements with Company, Company agrees that, notwithstanding anything to the contrary set forth in such Stock Option Agreements or Company’s Stock Incentive Plan, as may be amended from time to time, during the five-year period following the
Separation Date (but not after the end of each Option’s original term), Employee shall be permitted to exercise immediately all Options granted to Employee that have vested as of the Separation Date and those Options that would have vested
within one year of the Separation Date had Employee’s employment with Company not terminated. The parties hereto agree and acknowledge that, with respect to any Options previously granted to Employee that were intended by the parties to be
treated as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, such Options, to the extent they may be exercised by 

 
Employee more than 90 days following the Separation Date shall be treated as non-qualified Options, notwithstanding any provision in Employee’s Stock Option Agreements to the contrary.

 In the event that a Change in Control occurs, and Employee is not terminated, the vesting schedule of Options held by Employee
shall accelerate such that on the date the Change of Control is completed 50% of any unvested shares of Employee shall immediately vest and shall be exercisable during the five-year period following the Separation Date (but not after the end of each
Option’s original term) notwithstanding anything to the contrary set forth in Employee’s applicable Stock Option Agreements with the Company or Company’s Stock Incentive Plan; provided, however, that if, in connection with the
consummation of the transaction resulting in the Change in Control, Employee receives a cash payment with respect to each Option equal to the difference or “spread” between (i) the per share amount paid to holders of Common Stock in
such transaction and (ii) the per share exercise price under the applicable option agreement, his Options shall be cancelled upon the consummation of the Change in Control in exchange for such cash payment. 

If, in connection with or within the first two years after a Change in Control, Employee’s employment is terminated pursuant to
either of Sections 3.1.6 or 3.1.7, and Employee has executed a written release to Company in substantially the same form attached hereto as Exhibit A and the rescission period specified therein has expired, the vesting schedule of Options held by
Employee shall accelerate such that on the date the Change of Control is completed 100% of any unvested shares of Employee shall immediately vest and shall be exercisable during the five-year period following the Separation Date (but not after the
end of each Option’s original term) notwithstanding anything to the contrary set forth in Employee’s applicable Stock Option Agreements with the Company or Company’s Stock Incentive Plan; provided, however, that if, in connection with
the consummation of the transaction resulting in the Change in Control, Employee receives a cash payment with respect to each Option equal to the difference or “spread” between (i) the per share amount paid to holders of Common Stock
in such transaction and (ii) the per share exercise price under the applicable option agreement, his Options shall be cancelled upon the consummation of the Change in Control in exchange for such cash payment. The parties hereto agree and
acknowledge that, with respect to any Options previously granted to Employee that were intended by the parties to be treated as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended, such Options, to the extent they may be exercised by Employee more than 90 days following the Separation Date shall be treated as non-qualified Options, notwithstanding any provision in Employee’s Stock Option Agreements to the
contrary.”

 2. Section 3.3 of the Agreement is deleted in its entirety, and the following is
substituted in its place: 
 “3.3 Benefits Following Termination Prior to the End of the Term. In the event
that Employee’s employment is terminated pursuant to subsections 3.1.2; 3.1.3; 3.1.6; or 3.1.7 of Section 3.1 of this Agreement, Employee (if he survives) and his spouse and any eligible dependents shall, at the sole cost of the Company
(except for any share of the cost for benefits of his spouse and eligible dependents that Employee was required to pay immediately before the Separation Date), be entitled to continue to participate in Company-provided medical, dental, and life
insurance programs for a period of twelve (12) months following the Separation Date irrespective of any then pre-existing health conditions of Employee or his spouse or eligible dependents; provided, that such continued participation is not
prohibited by any applicable laws or would not otherwise jeopardize the tax qualified status of any such programs. The Company may discontinue any such coverage for which it does not receive timely payment of Employee’s share (if any) of the
cost due after the Separate Date. If Company is prohibited by applicable law or would otherwise jeopardize the tax qualified status of any medical, dental, or life insurance plan and as a result Company terminates coverage, it shall promptly
reimburse Employee (or Employee’s spouse or eligible dependents as the case may be) for the cost of obtaining comparable third party coverage irrespective of any then preexisting health conditions of Employee and/or his spouse or eligible
dependents. Any period of continuing coverage under this Section 3.2.3 shall run at the same time as the applicable continuing coverage required to be offered to Employee, his spouse or eligible dependents under applicable laws; and each of
them who has a right to continuing coverage under any such law shall be deemed to have timely elected continuing coverage under such law, to the extent the Company is required to provide continuing coverage under this paragraph. 

Except as otherwise provided in this Section 3.2.3, the benefits to which Employee (or, as applicable, Employee’s spouse,
eligible dependents or estate) may be entitled upon termination pursuant to the plans and policies of Company described Article II of this Agreement shall be determined and paid in accordance with such plans and policies.” 

3. Article III of the Agreement is amended by adding the following Section 3.2.5 to the Agreement: 

“3.2.5 Potential Delay of Severance Payments. If, as of the Separation Date, (a) Company’s common stock is publicly
traded (as determined under Code Section 409A), (b) Employee is a “specified employee” (as determined under Code Section 409A), and (c) any portion of the severance pay due Employee under Sections 3.2.1, 3.2.2 (if
applicable) or 3.2.3 would exceed the sum of the applicable limited separation pay exclusions as determined pursuant to Code Section 409A, then payment of the excess amount shall be delayed until the first regular payroll date of Company
following the six month anniversary of Employee’s Separation Date (or the date of his death, if earlier than that anniversary), and shall include a lump sum equal to the aggregate amounts that Employee would have received had payment of this
excess amount commenced 
  

 - 3 - 

 
as provided in Sections 3.2.1, 3.2.2 (if applicable) or 3.2.3 after the Separation Date. If Employee continues to perform any services for Company (as an employee or otherwise) after the
Separation Date, such six month period shall be measured from the date of Employee’s “separation from service” as defined pursuant to Code Section 409A.” 

4. Entire Agreement. The Agreement, as amended by this Amendment No. 1 (as so amended, the “Amended Agreement”),
contains the entire understanding between the parties hereto with respect to the subject matter hereof and shall supersede and terminate any prior understandings, agreements, obligations or representations, written or oral, relating to the subject
matter hereof, including, but not limited to the Agreement as originally executed. The parties agree that the Amended Agreement is the result of negotiations between the parties and that the language of the Amended Agreement shall not be construed
for or against any particular party. 
 5. Counterparts. This Amendment No. 1 may be executed in any number of
counterparts, all of which shall constitute a single agreement. Signatures delivered by facsimile transmission shall be deemed original signatures for all purposes. 

IN WITNESS WHEREOF, the parties have caused this Amendment No. 1 to the Agreement to be duly executed and delivered by their proper
and duly authorized representatives as of the day and year first above written.

 PRIORITY LIEN SECURITY AGREEMENT 

PRIORITY LIEN SECURITY AGREEMENT, dated as of April 19, 2010 (as amended, modified or supplemented from time to time, the
“Agreement”), between UNITED AIR LINES, INC., a Delaware corporation (“United”) (together with its permitted successors and assigns, the “Pledgor”) and WILMINGTON TRUST FSB, as Collateral Trustee
(together with its successors and permitted assigns, the “Collateral Trustee”), for the benefit of the Priority Lien Secured Parties. Except as otherwise defined herein, terms used herein and defined in the Collateral Trust
Agreement shall be used herein as therein defined. 
 W I T N E S S E
T H: 
 WHEREAS, the Pledgor and the Collateral Trustee are parties to (i) that certain Indenture dated as of
January 15, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Indenture”), by and among United, the Guarantors party thereto, the Collateral Trustee, and The Bank of New York Mellon Trust
Company, N.A., as trustee (together with its successors and permitted assigns, the “Indenture Trustee”), and (ii) that certain Collateral Trust Agreement dated as of January 15, 2010 (as amended, restated, supplemented or
otherwise modified from time to time, the “Collateral Trust Agreement”), by and among United, the Indenture Trustee and the Collateral Trustee; 

WHEREAS, in order to secure the Pledgor’s obligations under the Indenture and to induce the Escrow Agent to release the proceeds
from the Escrow Account to the Pledgor in accordance with the terms of the Escrow and Security Agreement, the Pledgor has agreed to grant a continuing Lien on the Collateral (as defined below) to secure the Priority Lien Obligations; 

WHEREAS, the Pledgor may, from time to time, incur additional Priority Lien Obligations in accordance with the terms of the Collateral
Trust Agreement and, in order to induce the applicable Priority Lien Representatives and holders of additional Priority Lien Obligations to enter into the applicable Priority Lien Documents and to make the applicable Priority Lien Debt available to
the Pledgor as provided therein, the Pledgor agrees to grant to the Collateral Trustee a continuing Lien on the Collateral (as defined below) to secure such additional Priority Lien Obligations; and 

WHEREAS, the Pledgor desires to execute this Agreement to satisfy the condition described in the preceding paragraphs; 

NOW, THEREFORE, in consideration of the benefits accruing to the Pledgor, the receipt and sufficiency of which are hereby acknowledged,
the Pledgor hereby makes the following representations and warranties to the Collateral Trustee and hereby covenants and agrees with the Collateral Trustee as follows: 

Section 1. Pledge. The Pledgor hereby pledges to the Collateral Trustee and grants to the Collateral Trustee for the benefit
of the Priority Lien Secured Parties a security interest in all of the following (the “Collateral”), to secure all of the Priority Lien Obligations: 

(i) all of the right, title and interest of the Pledgor in, to and under the Japan Routes, the Japan Slots, and the Japan
Gate Leaseholds from time to time; and 

 (ii) all of the right, title and interest of the Pledgor in, to and under
all Proceeds of any and all of the foregoing (including, without limitation, all Proceeds (of any kind) received or to be received by the Pledgor upon the transfer or other such disposition of such Collateral notwithstanding whether the pledge and
grant of the security interest in such Collateral is legally effective under applicable law); 
 provided, however, that
notwithstanding any other provision of this Agreement, this Agreement shall not constitute a grant of a security interest in any Japan Gate Leaseholds (and no such property shall be “Collateral” for purposes of this Agreement) to the
extent that such grant of a security interest is prohibited by any applicable law or a Governmental Authority or Airport Authority, requires a consent not obtained of any Governmental Authority or Airport Authority, or is prohibited by, or
constitutes a breach or default under or results in the termination of or requires any consent not obtained under, any contract, license, agreement, instrument or other document evidencing or giving rise to the Pledgor’s interest in such Japan
Gate Leaseholds, except to the extent that such applicable law, requirement or prohibition by any Governmental Authority or Airport Authority, or the term in such contract, license, agreement, instrument or other document or shareholder or similar
agreement providing for such prohibition, breach, default or termination or requiring such consent is ineffective under applicable law, including without limitation, the UCC; and provided further, that notwithstanding any other provision of
this Agreement, this Agreement shall not constitute a grant of a security interest in any Japan Route Foreign Slots to the extent the grant of such security interest is prohibited by applicable foreign law. 

Section 2. Obligations. This Agreement secures, and the Collateral is collateral security for, the Priority Lien Obligations.

 Section 3. No Release. Nothing set forth in this Agreement shall relieve the Pledgor from the performance of any
term, covenant, condition or agreement on the Pledgor’s part to be performed or observed under or in respect of any of the Collateral or from any liability to any Person under or in respect of any of the Collateral or impose any obligation on
the Collateral Trustee or any Priority Lien Secured Party to perform or observe any such term, covenant, condition or agreement on the Pledgor’s part to be so performed or observed or impose any liability on the Collateral Trustee or any
Priority Lien Secured Party for any act or omission on the part of the Pledgor relating thereto or for any breach of any representation or warranty on the part of the Pledgor contained in this Agreement, or in respect of the Collateral or made in
connection herewith or therewith. This Section 3 shall survive the termination of this Agreement and the discharge of the Pledgor’s other obligations hereunder and under the Priority Lien Documents. 

 

 2 

 Section 4. Representations, Warranties and Covenants. The Pledgor represents,
warrants and covenants as follows: 
 (i) All filings, registrations and recordings necessary or reasonably
requested by the Collateral Trustee or any Priority Lien Representative to create, preserve, protect and perfect the security interests granted by the Pledgor to the Collateral Trustee for the benefit of the Priority Lien Secured Parties in respect
of the Collateral have been accomplished by the Pledgor to the extent that such security interests can be perfected under the UCC and Title 49. The security interests granted to the Collateral Trustee for the benefit of the Priority Lien Secured
Parties pursuant to this Agreement in and to the Collateral constitute and hereafter at all times shall constitute a perfected security interest therein superior and prior to the rights of all other Persons therein, subject, in the case of priority
only, only to Permitted Liens, to the extent such perfection and priority can be obtained under the UCC or by filing a record of such security interest with the FAA, and the Collateral Trustee is entitled to all the rights, priorities and benefits
afforded by the UCC as enacted in any relevant jurisdiction and Title 49 to perfected security interests. 
 (ii)
There are no filings, registrations or recordings necessary to create, preserve, protect or perfect the security interests granted by the Pledgor to the Collateral Trustee for the benefit of the Priority Lien Secured Parties in respect of the
Collateral under Title 49. 
 (iii) The Pledgor is, and as to Collateral acquired by it from time to time after
the date hereof the Pledgor will be, the holder of all such Collateral free from any Lien or adverse claims except for (1) the Lien and security interest created by this Agreement and (2) Permitted Liens. The Pledgor shall use commercially
reasonable efforts to defend the Collateral against any and all claims and demands of all Persons at any time claiming any interest therein adverse to the Collateral Trustee or any Priority Lien Secured Party (other than Permitted Liens).

 (iv) There is no financing statement (or similar statement or instrument of registration under the law of any
jurisdiction) on the date hereof, covering or purporting to cover any interest of any kind in the Collateral, and so long as all of the Priority Lien Documents have not been terminated or any of the Priority Lien Obligations remain outstanding, the
Pledgor shall not execute or authorize to be filed in any public office any financing statement (or similar statement or instrument of registration under the law of any jurisdiction), or statements relating to the Collateral, except financing
statements (or similar statements or instruments of registration under the law of any jurisdiction) filed or to be filed in respect of and covering the security interests granted hereby by the Pledgor and except with respect to Liens permitted by
each applicable Priority Lien Document. 
 (v) The chief executive offices of the Pledgor as of the date of this
Agreement are located at 77 W. Wacker, Chicago, Illinois 60601. The Pledgor shall not, until it shall have given to the Collateral Trustee not less than 10 days’ prior written notice of its

  

 3 

 
intention to do so, (a) move its chief executive office from the location referred to in the previous sentence or change its jurisdiction of incorporation, or (b) change its name,
identity or corporate or other organizational structure to such an extent that any financing statement filed by the Collateral Trustee in connection with this Agreement would become misleading; and the Pledgor shall, in each case, provide such other
information in connection therewith as the Collateral Trustee or any Priority Lien Representative may reasonably request and shall have taken all action reasonably satisfactory to the Collateral Trustee and the Priority Lien Representatives to
maintain the perfection and priority of the security interest of the Collateral Trustee on behalf of the Secured Parties in the Collateral intended to be granted hereby. 

(vi) Set forth on Schedule I is a true, correct and complete list of the Japan Routes and Japan Slots at Tokyo’s
Narita Airport, in each case as of the date hereof, including a copy of each certificate or order issued by the DOT representing such Japan Routes. The Pledgor represents and warrants that it holds the requisite authority to operate over the Japan
Routes pursuant to Title 49 and all rules and regulations promulgated thereunder, subject only to the regulations of the DOT, the FAA and the applicable Japan Route Foreign Aviation Authority, and that it has, at all times after obtaining each such
Japan Route, complied in all material respects with all of the terms, conditions and limitations of each such certificate or order issued by the DOT and the rules and regulations of the applicable Japan Route Foreign Aviation Authority and with all
applicable provisions of Title 49 and applicable rules and regulations promulgated thereunder, and that there exists no material violation of such regulations, terms, conditions or limitations that gives the FAA, DOT or the applicable Japan Route
Foreign Aviation Authority the right to terminate, cancel, withdraw or modify the rights of the Pledgor in any such Japan Routes or Japan Slots. The Pledgor further represents and warrants that, as of the date hereof, none of the airports located in
the United States of America at which the Pledgor conducts scheduled operations for direct non-stop flights to Japan using the Japan Routes is a slot-constrained airport. If any of the airports located in the United States of America at which the
Pledgor conducts scheduled operations for direct non-stop flights to Japan using the Japan Routes is or becomes a slot-constrained airport after the date hereof, the Pledgor shall promptly notify the Collateral Trustee thereof. If at any time the
Pledgor shall hold or acquire any Japan Route FAA Slot, then the Pledgor shall promptly deliver to the Collateral Trustee a blank, undated, signed Japan Route FAA Slot transfer document (substantially in the form of Exhibit A hereto or such other
form reasonably satisfactory to the Collateral Trustee) with respect to such Japan Route FAA Slot to the extent such transfer document is applicable. 

(vii) The Pledgor is an “air carrier” within the meaning of Section 40102 of Title 49 and holds a
certificate under Section 41102 of Title 49. The Pledgor holds an air carrier operating certificate issued pursuant to Chapter 447 of Title 49. The Pledgor is a “citizen of the United States” as defined in Section 40102(a)(15) of
Title 49 and as that statutory provision has been interpreted by the DOT pursuant to its policies (a “United  
  

 4 

 
States Citizen”). The Pledgor possesses all necessary certificates, franchises, licenses, permits, rights, designations, authorizations, exemptions, concessions, frequencies and
consents which relate to the operation of the routes flown by it and the conduct of its business and operations as currently conducted except where failure to so possess would not, in the aggregate, have a material adverse effect on the business,
operations or financial condition of United and its subsidiaries, taken as a whole. As of the date hereof there are no license fees owed on the Pledgor’s DOT or FAA licenses, certificates or authorizations. The Pledgor is in compliance with all
material requirements of the certificates and authorizations issued to it by the DOT or the FAA. 
 (viii) The
Pledgor has full corporate power and authority and legal right to pledge all of the Collateral pursuant to this Agreement. 

(ix) Except for matters that would not reasonably be expected to result in a Material Adverse Effect, no consent of any
other party (including, without limitation, stockholders or creditors of the Pledgor), and no consent, authorization, approval, or other action by, and (except in connection with the perfection of the Lien created hereby) no notice to or filing
with, any Governmental Authority or other Person is required either (x) for the pledge by the Pledgor of the Collateral pursuant to this Agreement or for the execution, delivery or performance of this Agreement or (y) for the exercise by
the Collateral Trustee of the rights provided for in this Agreement or the remedies in respect of the Collateral pursuant to this Agreement; provided, however, that the (A) transfer of (other than the grant or pledge of a security
interest in) the Japan Routes is subject to the consent of the DOT pursuant to Section 41307 of Title 49 and is subject to Presidential review pursuant to Section 41307 of Title 49, (B) any transfer of (other than the grant or pledge
of a security interest in) Japan Route FAA Slots may be subject to confirmation by the FAA, (C) the transfer of (other than the grant or pledge of a security interest in) Japan Gate Leaseholds may be subject to approval by Governmental
Authorities or Airport Authorities, aviation authorities, air carriers or other lessors and (D) the transfer of (other than the grant or pledge of a security interest in) Japan Route Foreign Slots may be subject to approval by the applicable
Japan Route Foreign Aviation Authority or Airport Authorities. 
 (x) All information set forth herein relating
to the Collateral is accurate in all material respects as of the date hereof. 
 (xi) This Agreement is made with
full recourse to the Pledgor and pursuant to and upon all the warranties, representations, covenants and agreements on the part of the Pledgor contained herein. 

Section 5. Supplements, Further Assurances. The Pledgor agrees that at any time and from time to time, at the reasonable
expense of the Pledgor, the Pledgor will promptly execute, acknowledge and deliver all further security documents, instruments, certificates, notices and other documents, and take all further action, that may be reasonably required under, or
reasonably requested by the Collateral Trustee or any Priority Lien Representative with 
  

 5 

 
respect to, applicable law or by the DOT, Japan Route Foreign Aviation Authorities, Governmental Authorities, Airport Authorities, aviation authorities, air carriers or other lessors or that may
be required or that the Collateral Trustee or any Priority Lien Representative may reasonably request in order to create, perfect, protect, assure and enforce any security interest granted or purported to be granted or intended to be granted hereby
or to enable the Collateral Trustee to exercise and enforce its rights and remedies hereunder or under the Priority Lien Documents to which it is a party with respect to any Collateral, including, without limitation, any actions reasonably requested
by the Collateral Trustee or any Priority Lien Representative to register, record and identify the Collateral Trustee as a “Holder” of a Japan Route FAA Slot with the FAA and to cause evidence of its rights to be duly recorded, filed or
filed for recording, to the extent permitted or required under any applicable law, by the Pledgor as holder, and any actions reasonably requested by the Collateral Trustee or any Priority Lien Representative required to perfect, preserve and protect
any such security interest under other applicable laws. 
 Section 6. Provisions Concerning Pledged Collateral.

 (i) Financing Statements. The Pledgor hereby authorizes the Collateral Trustee, at any time and from
time to time, to file or record such financing statements which reasonably describe the Collateral and amendments thereto, in the form provided to it by the Pledgor, as may from time to time be required or necessary to grant, continue and maintain a
valid, enforceable, first priority security interest in the Collateral as provided herein (to the extent such perfection and priority can be obtained by filing a UCC financing statement), and the other rights, as against third parties, provided
hereby, all in accordance with the UCC as enacted in any and all relevant jurisdictions or any other relevant law. The Pledgor shall pay any applicable filing fees and other reasonable out-of-pocket expenses related to the filing of such financing
statements and amendments thereto. The Collateral Trustee hereby authorizes the Pledgor to file (i) financing statements and amendments to financing statements filed on the date hereof in each case adding Collateral and (ii) continuation
statements of any financing statement naming the Collateral Trustee, as secured party, and Pledgor, as debtor, in each case filed pursuant to the terms of this Agreement and the other Priority Lien Documents. 

(ii) Compliance with Laws and Regulations. Except for matters that would not reasonably be expected to result in a
Material Adverse Effect, the Pledgor shall promptly comply in all respects with all laws, ordinances, orders, rules, regulations, and requirements of all federal, state, municipal or other governmental or quasi-governmental authorities or bodies
including, without limitation, Japan Route Foreign Aviation Authorities, then having jurisdiction over the Collateral (or any part thereof) and/or the use thereof by the Pledgor, of every nature and kind (the “Requirements”)
including any of the same which relate to or require changes or requirements incident to or as the result of any use thereof or otherwise, and the Pledgor shall so comply, whether or not such Requirements shall now exist or shall hereafter be
enacted or promulgated and whether or not the same may be said to be within the present contemplation of the parties hereto. Notwithstanding the foregoing, if the Pledgor in good faith contests a Requirement, it

  

 6 

 
shall not be obligated to comply with such Requirement to the extent such non-compliance or deferral is consistent with law and does not have a material adverse effect on the Collateral or the
security interest therein. 
 (iii) Notice of Laws. The Pledgor agrees to give the Collateral Trustee
notice of any material violations of any Requirement enacted, passed, promulgated, made, issued or adopted by any of the governmental departments or agencies or authorities hereinbefore mentioned with respect to the Collateral or the Pledgor’s
use thereof, a copy of which is served upon or received by the Pledgor, or otherwise brought to the attention of a responsible officer of the Pledgor, by mailing within fifteen (15) Business Days after such service, receipt, or after the same
otherwise comes to the attention of the Pledgor, a copy of each and every one thereof to the Collateral Trustee. At the same time, the Pledgor will inform the Collateral Trustee as to the work or steps which the Pledgor proposes to do or take in
order to correct any such material violation. Notwithstanding the foregoing, however, if such work or step would require any alterations which would, in the Pledgor’s reasonable opinion, reduce the value of the Collateral or change the general
character or use of the Collateral, the Pledgor may defer compliance therewith, as long as such deferral is consistent with applicable law in order that the Pledgor may, at the Pledgor’s expense, contest or seek modification of or other relief
with respect to such Requirements, but nothing herein shall relieve the Pledgor of the duty and obligation, at the Pledgor’s expense, to comply with such Requirements, or such Requirements as modified, whenever the Collateral Trustee shall so
direct. 
 Section 7. Collateral Trustee Appointed Attorney-in-Fact. The Pledgor hereby appoints the Collateral
Trustee as the Pledgor’s attorney-in-fact, with full authority in the place and stead of the Pledgor and in the name of the Pledgor or otherwise, from time to time in the Collateral Trustee’s discretion, upon the occurrence and during the
continuation of an Event of Default, to take any action and to execute any instrument which the Collateral Trustee may reasonably deem necessary or advisable to accomplish the purposes of this Agreement, which appointment as attorney-in-fact is
coupled with an interest. 
 Section 8. Collateral Trustee May Perform. If the Pledgor fails to perform any
agreement contained herein within a reasonable time after receipt of a written request to do so from the Collateral Trustee, upon 2 Business Days prior written notice the Collateral Trustee may itself perform, or cause performance of, such
agreement, and the reasonable expenses of the Collateral Trustee, including, without limitation, the reasonable fees and out-of-pocket expenses of its counsel, incurred in connection therewith, shall be payable by the Pledgor in accordance with
Section 7.10 of the Collateral Trust Agreement and shall be considered Obligations. 
 Section 9. The Collateral
Trustee. It is expressly understood and agreed by the parties hereto, and each Priority Lien Secured Party, by accepting the benefits of this Agreement, acknowledges and agrees, that the obligations of the Collateral Trustee as holder of the
Collateral and interests therein and with respect to the disposition thereof, and otherwise under this Agreement, are only those expressly set forth in this Agreement. The Collateral Trustee shall act hereunder on the terms and conditions set forth
in the Collateral Trust 
  

 7 

 
Agreement. In the event of any express conflict between the terms of this Agreement and the terms of the Collateral Trust Agreement, the Collateral Trust Agreement shall control and govern,
provided that this provision shall not be interpreted in any way to affect any rights expressly provided to the Priority Lien Secured Parties under this Agreement unless such rights are expressly prohibited or restricted under the Collateral
Trust Agreement. 
 Section 10. Events of Default, Remedies: 

A. Remedies: Obtaining the Collateral Upon Event of Default. If any Event of Default shall have occurred and be continuing, then
and in every such case, the Collateral Trustee may, at any time or from time to time during the continuance of such Event of Default: 

(i) Declare the entire right, title and interest of the Pledgor in and to the Collateral vested, subject to any binding
and enforceable mandatory requirements imposed by applicable law and the DOT (and, in the case of Japan Gate Leaseholds, the requirements imposed by the applicable Governmental Authorities and/or Airport Authorities), in which event such rights,
title and interest shall immediately vest in the Collateral Trustee, in which case the Pledgor agrees to execute and deliver such deeds of conveyance, assignments and other documents or instruments (including any notices or applications to the DOT,
FAA, applicable Japan Route Foreign Aviation Authorities, Governmental Authorities or Airport Authorities having jurisdiction over any such Japan Route or the use thereof) as shall be requested by the Collateral Trustee in order to effectuate the
transfer of such Collateral, together with copies of the certificates or orders issued by the DOT and the Japan Route Foreign Aviation Authorities representing same and any other rights of the Pledgor with respect thereto, to any designee or
designees selected by the Collateral Trustee and approved by the DOT and, to the extent necessary, by any Japan Route Foreign Aviation Authorities; it being understood that the Pledgor’s obligation to deliver such Collateral and such documents
and instruments with respect thereto is of the essence of this Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Collateral Trustee shall be entitled to a decree requiring specific performance by the
Pledgor of said obligations; and 
 (ii) Sell or otherwise liquidate, or direct the Pledgor to sell or otherwise
liquidate, any or all of the Collateral or any part thereof and take possession of the proceeds of any such sale or liquidation, in each case subject to any binding and enforceable mandatory requirements imposed by applicable law and Airport
Authorities with respect to Japan Gate Leaseholds. 
 B. Remedies; Disposition of the Collateral. 

(i) If any Event of Default shall have occurred and be continuing, the Collateral Trustee may from time to time exercise
in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, and to the extent not in violation of applicable law, including Title 49, and subject to the approval of the DOT or its
successor or nominee, all the rights and remedies of a secured party on 
  

 8 

 
default under the UCC in effect in all relevant jurisdictions at the time of such Event of Default, and the Collateral Trustee may also in its sole discretion, without notice except as specified
below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of the Collateral Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and at
such price or prices and upon such other terms as the Collateral Trustee may deem commercially reasonable. To the extent not inconsistent with Title 49 and the DOT or FAA requirements and any additional requirements of the applicable Governmental
Authorities and/or Airport Authorities, the Collateral Trustee or any other Priority Lien Secured Party may be the purchasers of any or all of the Collateral at any such sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at such sale, to use and apply any of the Priority Lien Obligations owed to such Person as a credit on account of the purchase price of any Collateral payable by such Person
at such sale. Each purchaser at any such sale shall acquire the property sold absolutely free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives, to the fullest extent permitted by law, all rights of redemption, stay
or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to
the Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Trustee shall not be obligated to make any sale of Collateral regardless of notice
of sale having been given. The Collateral Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was
so adjourned. The Pledgor hereby waives, to the full extent permitted by law, any claims against the Collateral Trustee arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the
price which might have been obtained at a public sale. 
 (ii) Except as otherwise provided herein, the Pledgor
hereby waives, to the fullest extent permitted by applicable law, notice or judicial hearing in connection with the Collateral Trustee’s taking possession or the Collateral Trustee’s disposition of any of the Collateral, including, without
limitation, any and all prior notice and hearing for any prejudgment remedy or remedies and any such right which the Pledgor would otherwise have under law; and the Pledgor hereby further waives to the fullest extent permitted by applicable law:
(a) all damages occasioned by such taking of possession; (b) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Trustee’s rights hereunder; and
(c) all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable law. Any sale of, or the grant of options to purchase, or any other realization upon, any Collateral shall
operate to divest all right, title, interest, claim and demand, either at law or in equity, of the Pledgor therein and thereto, and shall be a perpetual bar both at law and in equity against the Pledgor and against any and all Persons claiming or
attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from, through and under the Pledgor. 
  

 9 

 (iii) If any Event of Default shall have occurred and be continuing, then
the Collateral Trustee may use the blank, undated, signed Japan Route FAA Slot transfer documents held by it from time to time (substantially in the form of Exhibit A hereto) as a means to effectuate a transfer as contemplated herein, subject in
each case to applicable law. 
 (iv) In connection with any foreclosure, collection, sale or other enforcement of
Liens granted to the Collateral Trustee in this Agreement, the Pledgor will cooperate in good faith with the Collateral Trustee or its designee in obtaining all regulatory licenses, consents and other governmental approvals necessary or (in the
opinion of the Collateral Trustee or its designee) desirable to conduct all aviation operations with respect to the Collateral and will, at the request of the Collateral Trustee and in good faith, continue to operate and manage the Collateral and
maintain all applicable regulatory licenses with respect to the Collateral until such time as the Collateral Trustee or its designee obtain such licenses, consents and approvals, and at such time the Pledgor will cooperate in good faith with the
transition of the aviation operations with respect to the Collateral to any new aviation operator (including, without limitation, the Collateral Trustee or its designee). 

Section 11. Application of Proceeds. 

(a) Any cash held by the Collateral Trustee as Collateral and all cash proceeds received by the Collateral Trustee in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral pursuant to the exercise by the Collateral Trustee of its remedies as a secured creditor as provided in Section 10 of this Agreement shall be applied from time to
time by the Collateral Trustee in accordance with the terms of the Collateral Trust Agreement. 
 (b) It is understood that the
Pledgor shall remain liable to the extent of any deficiency between the amount of the proceeds of the Collateral and the aggregate amount of the outstanding Priority Lien Obligations. 

Section 12. No Waiver; Discontinuance of Proceeding. 

(a) Each and every right, power and remedy hereby specifically given to the Collateral Trustee or otherwise in this Agreement shall be
cumulative and shall be in addition to every other right, power and remedy specifically given under this Agreement or the other Priority Lien Documents 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 be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Collateral Trustee. All such rights, powers and remedies shall be
cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right 
  

 10 

 
to exercise any other or others. No delay or omission of the Collateral Trustee in the exercise of any such right, power or remedy and no renewal or extension of any of the Priority Lien
Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any default or Event of Default or an acquiescence therein. No notice to or demand on the Pledgor in any case shall entitle it to any other or further
notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Collateral Trustee to any other or further action in any circumstances without notice or demand. In the event that the Collateral Trustee shall
bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Collateral Trustee may recover reasonable out-of-pocket expenses, including reasonable attorneys’ fees, and the amounts thereof shall
be included in such judgment. 
 (b) In the event the Collateral Trustee shall have instituted any proceeding to enforce any
right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Trustee, then and in every
such case the Pledgor, the Collateral Trustee and each holder of any of the Priority Lien Obligations shall to the extent permitted by applicable law be restored to their respective former positions and rights hereunder with respect to the
Collateral, and all rights, remedies and powers of the Collateral Trustee and the Priority Lien Secured Parties shall continue as if no such proceeding had been instituted. 

Section 13. [Reserved]. 

Section 14. Amendments, etc. This Agreement may not be amended, modified or waived except with the written consent of the
Pledgor and the Collateral Trustee (acting pursuant to and in accordance with the terms of the Collateral Trust Agreement). Any amendment, modification or supplement of or to any provision of this Agreement, any termination or waiver of any
provision of this Agreement and any consent to any departure by the Pledgor from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which made or given. No notice to or
demand upon the Pledgor in any instance hereunder shall entitle the Pledgor to any other or further notice or demand in similar or other circumstances. 

Section 15. Termination; Release. 

(a) Upon the Discharge of Priority Lien Obligations, this Agreement shall automatically terminate (provided that all indemnities set
forth in the Collateral Trust Agreement shall survive) and the Collateral Trustee, at the request and expense of the Pledgor, will promptly execute and deliver to the Pledgor a proper instrument or instruments acknowledging the satisfaction and
termination of this Agreement, and, subject to the terms of the Collateral Trust Agreement, will duly assign, transfer and deliver to the Pledgor (without recourse and without any representation or warranty) such of its Collateral as may be in the

Lien Obligations shall have occurred.

 (b) The Liens on the Collateral created by this Agreement shall be released in accordance

that Collateral be released as provided in the foregoing Section 15(a) or (b), it shall deliver to the Collateral Trustee a certificate signed by its chief financial officer or another authorized senior officer stating that the release of the
respective Collateral is permitted pursuant to Section 15(a) or (b). The Collateral Trustee shall have no liability whatsoever to any Priority Lien Secured Party as the result of any release of Collateral by it as permitted by this

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other

the Pledgor under this Agreement shall be adjudicated to be invalid or unenforceable for any reason 
  

 17 

 
(including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers, which laws would determine the solvency of the Pledgor by reference
to the full amount of the Priority Lien Obligations at the time of the execution and delivery of this Agreement), then the amount of the Priority Lien Obligations of the Pledgor shall be deemed to be reduced and the Pledgor shall pay the maximum
amount of the Priority Lien Obligations which would be permissible under the applicable law.
