Item 1.01 Entry into a Material Definitive Agreement.

On February 1, 2021 (the “Issuance Date”), United Airlines, Inc. (the “Company”) and Wilmington Trust, National Association, as mortgagee (the “Mortgagee”), subordination agent under the Intercreditor Agreement (as defined below) and pass through trustee (the “Trustee”) under each of the United Airlines Pass Through Trust 2020-1A (the “Class A Trust”) and the United Airlines Pass Through Trust 2020-1B (the “Class B Trust”), entered into the Class B Note Purchase Agreement, dated as of the Issuance Date (the “Note Purchase Agreement”). The Note Purchase Agreement was entered into in connection with the public offering by the Company of $600,000,000 face amount of United Airlines Class B Pass Through Certificates, Series 2020-1 (the “Class B Certificates”). Previously, on October 28, 2020, the Company sold $3,000,000,000 face amount of United Airlines Class A Pass Through Certificates, Series 2020-1 (the “Class A Certificates”), which are of the same series as the Class B Certificates.

Pursuant to the Note Purchase Agreement, on the Issuance Date, the Company issued for the benefit of the Class B Trust a Series B equipment note (the “Series B Equipment Note”) in the aggregate principal amount of $600,000,000. The Series B Equipment Note was issued under the Trust Indenture and Mortgage, dated as of October 28, 2020 between the Company and the Mortgagee (the “Original Indenture”), as amended by Amendment No. 1 to Trust Indenture and Mortgage, dated as of February 1, 2021 between the Company and the Mortgagee (the “Amendment”, and the Original Indenture, as amended by the Amendment, the “Indenture”). The Company entered into the Original Indenture in connection with the earlier sale by the Company of the Class A Certificates. In connection with such sale, the Company issued for the benefit of the Class A Trust a Series A equipment note (the “Series A Equipment Note” and, together with the Series B Equipment Note, the “Equipment Notes”). The Amendment revised the Original Indenture to provide, among other things, for the issuance of the Series B Equipment Note. The Series B Equipment Note is subordinated as to payment to the Series A Equipment Note pursuant to the Indenture. The Equipment Notes have been initially secured by substantially all of the Company’s aircraft spare parts from time to time, as well as by a designated group of 99 spare engines and 352 aircraft owned by the Company.

The Series B Equipment Note was purchased on the Issuance Date at a purchase price of 100% of the principal amount thereof using the proceeds of the offering of the Class B Certificates. The Company will use the proceeds from the sale of the Series B Equipment Note to pay fees and expenses relating to the offering of the Class B Certificates and for the Company’s general corporate purposes.

The Series B Equipment Note bears interest at a rate per annum of 4.875%. Interest on the Series B Equipment Note is payable quarterly on January 15, April 15, July 15 and October 15 of each year, beginning April 15, 2021. Principal payments on the Series B Equipment Note are scheduled on January 15, April 15, July 15 and October 15 of each year, beginning on April 15, 2021, with the final payment due on January 15, 2026. Payments on the Series B Equipment Note held for the benefit of the Class B Trust will be passed through to the holders of the Class B Certificates, subject to the Amended and Restated Intercreditor Agreement,

dated as of the Issuance Date, among the Trustee, Goldman Sachs Bank USA, Barclays Bank PLC, Morgan Stanley Bank, N.A., Citibank, N.A. and Credit Suisse AG, New York Branch, as liquidity providers, and Wilmington Trust, National Association, as subordination agent and trustee (the “Intercreditor Agreement”).

Pursuant to the Indenture, the Company is required to deliver to the Mortgagee semiannually separate appraisals of each of the following included in the collateral: (i) the spare parts, (ii) the spare engines, (iii) the aircraft less than 20 years old as of August 31, 2020 (the “Tier I Aircraft”) and (iv) the aircraft 20 years or older as of such date and certain specified models of aircraft regardless of age (the “Tier II Aircraft”). If the loan to value ratio determined pursuant to such appraisals of any of the following three groups of collateral (each, a “Collateral Group”): (i) the spare parts and spare engines, collectively, (ii) the Tier I Aircraft or (iii) the Tier II Aircraft, is greater than the specified maximum loan to value ratio applicable to such Collateral Group (an “LTV Breach”), the Company will be required to do one or more of the following, which in the aggregate cures such LTV Breach:

(a)	grant a security interest in certain additional collateral;
(b)	deposit with the Mortgagee cash or certain permitted investments as additional collateral; or
(c)	pay to the Mortgagee not less than the difference between the specified minimum collateral value for the applicable Collateral Group and the appraised value of the applicable Collateral Group, to be applied to redeem the Equipment Notes.

Maturity of the Equipment Notes may be accelerated upon the occurrence of certain events of default, including failure by the Company (in some cases after notice or the expiration of a grace period, or both) to make payments under the Indenture when due or to comply with certain covenants, as well as certain bankruptcy events involving the Company.

The Class B Certificates were registered for offer and sale pursuant to the Securities Act of 1933, as amended (the “Securities Act”), under the Company’s automatic shelf registration statement on Form S-3 (File No. 333-250153) (the “Registration Statement”). The Class B Certificates were offered pursuant to a final Prospectus Supplement of the Company, dated January 25, 2021, to the Prospectus, dated November 17, 2020 (the “Prospectus Supplement”).

The foregoing description of these agreements and instruments is qualified in its entirety by reference to these agreements and instruments, copies of which are filed herewith as exhibits (or, if executed in connection with the offering by the Company of the Class A Certificates, were filed as exhibits to the Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission on November 3, 2020) and are incorporated by reference herein.

The Class B Trust Supplement is related to the creation and administration of United Airlines Pass Through Trust 2020-1B (the “Class B Trust” and, together with the Class A Trust, the “Trusts”). As used herein, unless the context otherwise requires, the term “Underwriters” shall mean the firms named as Underwriters in Schedule II, and the term “Representative” shall mean Goldman Sachs & Co. LLC (“GS”), on behalf of the Underwriters.

(ii) The documents incorporated by reference in the Time of Sale Prospectus or the Prospectus pursuant to Item 12 of Form S-3 under the Securities Act, at the time they were filed with the Commission or hereafter, during the period mentioned in Section 4(a) hereof, are filed with the Commission, complied or will comply, as the case may be, in all material respects with the requirements of the Exchange Act.

lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified would not have a material adverse effect on the condition (financial or otherwise), business, properties or results of operations of the Company and its consolidated subsidiaries taken as a whole (a “United Material Adverse Effect”).

(v) Air Micronesia, LLC (the “Subsidiary”) has been duly formed and is a limited liability company in good standing under the laws of the jurisdiction of its formation, with limited liability company power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Prospectus; and the Subsidiary is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified would not have a United Material Adverse Effect; all of the membership interests of the Subsidiary have been duly authorized and validly issued and are fully paid and nonassessable; and, except as described in the Time of Sale Prospectus, the Subsidiary’s membership interests are owned by the Company, directly or through subsidiaries, free from liens, encumbrances and defects.

The execution, delivery and performance of this Agreement and the Operative Agreements to which the Company is or will be a party and the consummation by the Company of the transactions contemplated herein and therein have been duly authorized by all necessary corporate action of the Company and will not result in any breach of any of the terms, conditions or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance (other than any lien, charge or encumbrance created under any Operative Agreement) upon any property or assets of the Company pursuant to any indenture, loan agreement, contract, mortgage, note, lease or other instrument to which the Company is a party or by which the Company may be bound or to which any of the property or assets of the Company is subject, which breach, default, lien, charge or encumbrance, individually or in the aggregate, would have a United Material Adverse Effect, nor will any such execution, delivery or performance result in any violation of the provisions of the charter or by-laws of the Company or any statute, any rule, regulation or order of any governmental agency or body or any court having jurisdiction over the Company.

(vii) No consent, approval, authorization or order of, or filing with, any governmental agency or body or any court is required for the valid authorization, execution and delivery by the Company of this Agreement and the Operative Agreements to which it is or will be a party and for the consummation of the transactions contemplated herein and therein, except (x) such as may be required under the Securities Act, the Trust Indenture Act, the securities or “blue sky” or similar laws of the various states and of foreign jurisdictions or rules and regulations of the Financial Industry

(x) The Operative Agreements to which the Company is or will be a party, when duly executed and delivered by the Company, assuming that such Operative Agreements have been duly authorized, executed and delivered by, and constitute legal, valid and binding obligations of, each other party thereto, will constitute valid and binding obligations of the Company enforceable in accordance with their terms, except (w) as enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally, (x) as enforcement thereof is subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law), (y) that the enforceability of the Security Agreements may also be limited by applicable laws which may affect the remedies provided therein but which do not affect the validity of the Security Agreements or make such remedies inadequate for the practical realization of the benefits intended to be provided thereby and (z) with respect to indemnification and contribution provisions, as enforcement thereof may be limited by applicable law. The Basic Agreement has been duly qualified under the Trust Indenture Act.

(a) During the period described in the following sentence of this Section 4(a), the Company shall advise the Representative promptly of any proposal to amend or supplement the Registration Statement, the Time of Sale Prospectus or the Prospectus (except by documents filed under the Exchange Act) and will not effect such amendment or supplement (except by documents filed under the Exchange Act) without the consent of the Representative, which consent will not be unreasonably withheld. If, at any time after the public offering of the Class B Certificates, the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales of the Class B Certificates by an Underwriter or a dealer, any event shall occur as a result of which it is necessary to amend or supplement the Prospectus so that the statements therein will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, contain a material misstatement or omission, or if it is necessary to amend the Registration Statement or amend or supplement the Prospectus to comply with law, the Company shall prepare and furnish at its expense to the

Underwriters and to the dealers (whose names and addresses the Representative will furnish to the Company) to which Class B Certificates may have been sold by the Representative on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, contain a material misstatement or omission, or amendments or supplements to the Registration Statement or the Prospectus so that the Registration Statement or the Prospectus, as so amended or supplemented, will comply with law and cause such amendments or supplements to be filed promptly with the Commission.

(b) During the period mentioned in paragraph (a) above, the Company shall notify each Underwriter immediately of (i) the effectiveness of any amendment to the Registration Statement, (ii) the transmittal to the Commission for filing of any supplement to the Prospectus or any document that would as a result thereof be incorporated by reference in the Prospectus, (iii) the receipt of any comments from the Commission with respect to the Registration Statement or the Prospectus, (iv) any request by the Commission to the Company for any amendment to the Registration Statement or any supplement to the Prospectus or for additional information relating thereto or to any document incorporated by reference in the Prospectus and (v) receipt by the Company of any notice of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, the suspension of the qualification of the Class B Certificates for offering or sale in any jurisdiction, or the institution or threatening of any proceeding for any of such purposes; and the Company agrees to use every reasonable effort to prevent the issuance of any such stop order and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment and the Company shall endeavor (subject to the proviso to Section 4(g)), in cooperation with the Underwriters, to prevent the issuance of any such stop order suspending such qualification and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment.

(c) During the period mentioned in paragraph (a) above, the Company will furnish to each Underwriter as many conformed copies of the Registration Statement (as originally filed), the Time of Sale Prospectus, the Prospectus, and all amendments and supplements to such documents (excluding all exhibits and documents filed therewith or incorporated by reference therein) and as many conformed copies of all consents and certificates of experts, in each case as soon as available and in such quantities as each Underwriter reasonably requests.

(d) Promptly following the execution of this Agreement, the Company will prepare a Prospectus that complies with the Securities Act and that sets forth the face amount of the Class B Certificates and their terms not otherwise specified in the preliminary prospectus or the Basic Prospectus included in the Registration Statement, the name of each Underwriter and the face amount of the Class B Certificates that each severally has agreed to purchase, the name of each Underwriter, if any, acting as a representative of the Underwriters in connection with the offering, the price at which the Class B Certificates are to be purchased by the Underwriters from the Class B Trustee, any initial public offering price, any selling concession and reallowance and any delayed delivery arrangements, and such other information as the Representative and the Company deem appropriate in connection with the offering of the Class B Certificates. The

Company will timely transmit copies of the Prospectus to the Commission for filing pursuant to Rule 424 under the Securities Act.

(e) The Company shall furnish to each Underwriter a copy of each free writing prospectus relating to the offering of the Class B Certificates prepared by or on behalf of, used by, or referred to by the Company and shall not use or refer to any proposed free writing prospectus to which the Representative reasonably objects.

(f) If the Time of Sale Prospectus or any “issuer free writing prospectus” is being used to solicit offers to buy the Class B Certificates at a time when a Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” in order to make the statements therein, in the light of the circumstances when it is delivered to a prospective purchaser, not misleading in any material respect, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus or any “issuer free writing prospectus” conflicts with the information contained in the Registration Statement then on file, or if it is necessary to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” to comply with applicable law, the Company shall forthwith prepare, file promptly with the Commission and furnish, at the Company’s expense, to the Underwriters and to the dealers (whose names and addresses the Representative will furnish to the Company) to which Class B Certificates may have been sold by the Representative on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Time of Sale Prospectus or such “issuer free writing prospectus” so that the statements in the Time of Sale Prospectus or such “issuer free writing prospectus” as so amended or supplemented will not, in the light of the circumstances when it is delivered to a prospective purchaser, be misleading in any material respect or so that the Time of Sale Prospectus or such “issuer free writing prospectus”, as so amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus or such “issuer free writing prospectus”, as amended or supplemented, will comply with applicable law.

(g) The Company shall, in cooperation with the Underwriters, endeavor to arrange for the qualification of the Class B Certificates for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representative reasonably designates and will endeavor to maintain such qualifications in effect so long as required for the distribution of such Class B Certificates; provided that the Company shall not be required to (i) qualify as a foreign corporation or as a dealer in securities, (ii) file a general consent to service of process or (iii) subject itself to taxation in any such jurisdiction.

(h) During the period of ten years after the Closing Date, the Company will promptly furnish to each Underwriter, upon request, copies of all Annual Reports on Form 10-K and any definitive proxy statement of the Company (including any successor by merger of the Company) filed with the Commission; provided that (a) filing such documents with the Commission or (b) providing a website address at which such Annual Reports and any such definitive proxy statements may be accessed will satisfy this clause (h).

(i) If the third anniversary of the initial effective date of the Registration Statement occurs before all the Class B Certificates have been sold by the Underwriters, then prior to the third anniversary, the Company shall file a new shelf registration statement and take any other action necessary to permit the public offering of the Class B Certificates to continue without interruption, in which case references herein to the Registration Statement shall include the new registration statement as it shall become effective.

(j) Between the date of this Agreement and the Closing Date, the Company shall not, without the prior written consent of the Representative, offer, sell or enter into any agreement to sell (as public debt securities registered under the Securities Act (other than the Class B Certificates and related Series B Equipment Note, or a junior class of pass through certificates with respect to a previously issued series and related equipment note) or as debt securities which may be resold in a transaction exempt from the registration requirements of the Securities Act in reliance on Rule 144A thereunder and which are marketed through the use of a disclosure document containing substantially the same information as a prospectus for similar debt securities registered under the Securities Act), any equipment notes, pass through certificates, equipment trust certificates or equipment purchase certificates secured by aircraft, spare engines or spare parts owned by the Company (or rights relating thereto).

(k) The Company shall prepare a final term sheet relating to the offering of the Class B Certificates, containing only information that describes the final terms of the Class B Certificates or the offering in a form consented to by the Representative and shall file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Class B Certificates.

(l) The Company shall use the proceeds from the sale of the Series B Equipment Note as described under the heading “Use of Proceeds” in the Time of Sale Prospectus.

5. Certain Covenants of the Underwriters. (a) Each Underwriter represents, warrants and covenants that it has not made and will not make any offer relating to the Class B Certificates that would constitute an issuer free writing prospectus; provided that this Section 5 shall not prevent any Underwriter from transmitting or otherwise making use of one or more customary “Bloomberg Screens” to offer the Class B Certificates or convey final pricing terms thereof that contain only information contained in the Time of Sale Prospectus and (b) each Underwriter represents and agrees that it has not offered, sold, distributed or otherwise made available and will not offer, sell, distribute or otherwise make available any Class B Certificates to any retail investor in the European Economic Area.

6. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter and the affiliates of each Underwriter who have, or are alleged to have, participated in the distribution of the Class B Certificates as underwriters, and each Person, if any, who controls such Underwriter, within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any Underwriter or any such controlling person in connection with defending or

investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any “issuer free writing prospectus” as defined in Rule 433(h) under the Securities Act, any “issuer information” that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or the Prospectus, or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any of the aforementioned losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company in writing by any Underwriter through the Representative expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus, or any amendment or supplement thereto (the “Underwriter Information”).

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company, within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to such Underwriter but only with reference to the Underwriter Information provided by such Underwriter.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) above, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such paragraph. The indemnifying party, upon request of the indemnified party, shall, and the indemnifying party may elect to, retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and the indemnifying party shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, or (iii) the indemnifying party shall have failed to retain counsel as required by the prior sentence to represent the indemnified party within a reasonable amount of time. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representative in the case of parties indemnified pursuant to paragraph (a) above and by the Company in the case of parties indemnified pursuant to paragraph (b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled

with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested in writing an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph (c), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement, unless such fees and expenses are being disputed in good faith. The indemnifying party at any time may, subject to the last sentence of this paragraph (c), settle or compromise any proceeding described in this paragraph (c), at the expense of the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) To the extent the indemnification provided for in paragraph (a) or (b) of this Section 6 is required to be made but is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the applicable indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Class B Certificates or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of such Class B Certificates shall be deemed to be in the same respective proportions as the proceeds from the offering of such Class B Certificates received by the Class B Trust (before deducting expenses), less total underwriting discounts and commissions received by the Underwriters, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of such Class B Certificates. The relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or information supplied by any Underwriters, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to

contribute pursuant to this Section 6 are several in proportion to the respective face amount of Class B Certificates they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Class B Certificates underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) The indemnity and contribution provisions contained in this Section 6 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company, and (iii) acceptance of and payment for any of the Class B Certificates. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Class B Certificates hereunder and the aggregate face amount of the Class B Certificates that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total face amount of the Class B Certificates, the Representative may make arrangements satisfactory to the Company for the purchase of such Class B Certificates by other persons, including any of the non-defaulting Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Class B Certificates that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate face amount of the Class B Certificates with respect to which such default or defaults occurs exceeds 10% of the total face amount of the Class B Certificates and arrangements satisfactory to the Representative and the Company for purchase of such Class B Certificates by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 6. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

8. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any termination of this Agreement, any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Class B Certificates. If for any reason the purchase of the Class B Certificates by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 10 hereof and the respective obligations of the Company and the Underwriters pursuant to Section 6 hereof shall remain in effect. If the purchase of the Class B Certificates by the Underwriters is not consummated for any reason other than solely because of the occurrence of the termination of the Agreement pursuant to Section 7 or 9 hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by the Underwriters in connection with the offering of such Class B Certificates and comply with its obligations under Sections 6 and 10 hereof.

9. Termination. This Agreement shall be subject to termination by notice given by the Representative to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been materially suspended or materially limited on or by, as the case may be, either of the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Company or United Airlines Holdings, Inc. shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, (iv) there shall have occurred any attack on, or outbreak or escalation of hostilities or act of terrorism involving, the United States, or any change in financial markets or any calamity or crisis that, in each case, in the judgment of the Representative, is material and adverse or (v) there shall have occurred any major disruption of settlements of securities or clearance services in the United States that would materially impair settlement and clearance with respect to the Class B Certificates and (b) in the case of any of the events specified in clauses (a)(i) through (v), such event singly or together with any other such event makes it, in the judgment of the Representative, impracticable to market the Class B Certificates on the terms and in the manner contemplated in the Time of Sale Prospectus.

10. Payment of Expenses. As between the Company and the Underwriters, the Company shall pay all expenses incidental to the performance of the Company’s obligations under this Agreement, including the following:

(i) expenses incurred in connection with (A) qualifying the Class B Certificates for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representative reasonably designates (including filing fees and fees and disbursements of counsel for the Underwriters in connection therewith), (B) endeavoring to maintain such qualifications in effect so long as required for the distribution of such Class B Certificates, (C) the review (if any) of the offering of the Class B Certificates by FINRA, (D) the determination of the eligibility of the Class B Certificates for investment under the laws of such jurisdictions as the Underwriters may

designate and (E) the preparation and distribution of any blue sky or legal investment memorandum by Underwriters’ counsel;

(ii) expenses incurred in connection with the preparation and distribution to the Underwriters and the dealers (whose names and addresses the Underwriters will furnish to the Company) to which Class B Certificates may have been sold by the Underwriters on their behalf and to any other dealers upon request, either of (A) amendments to the Registration Statement or amendments or supplements to the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not materially misleading or (B) amendments or supplements to the Registration Statement, the Time of Sale Prospectus, or the Prospectus so that the Registration Statement, the Time of Sale Prospectus or the Prospectus, as so amended or supplemented, will comply with law and the expenses incurred in connection with causing such amendments or supplements to be filed promptly with the Commission, all as set forth in Section 4(a) hereof;

(iii) the expenses incurred in connection with the preparation, printing and filing of the Registration Statement (including financial statements and exhibits), as originally filed and as amended, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any issuer free writing prospectus and any amendments and supplements to any of the foregoing, including the filing fees payable to the Commission relating to the Class B Certificates (within the time period required by Rule 456(b)(1), if applicable), and the cost of furnishing copies thereof to the Underwriters and dealers;

(iv) expenses incurred in connection with the preparation, printing and distribution of this Agreement, the Class B Certificates and the Operative Agreements;

(v) expenses incurred in connection with the delivery of the Class B Certificates to the Underwriters;

(vi) reasonable fees and disbursements of the counsel and accountants for the Company;

(vii) to the extent the Company is so required under any Operative Agreement to which it is a party, the fees and expenses of the Mortgagee, the Subordination Agent, the Class B Trustee and the Liquidity Providers and the reasonable fees and disbursements of their respective counsel;

(viii) fees charged by rating agencies for rating the Class B Certificates (including annual surveillance fees related to the Class B Certificates as long as they are outstanding);

(ix) all fees and expenses relating to appraisals of the Aircraft, the Spare Engines and the Spare Parts;

(x) all other reasonable out-of-pocket expenses incurred by the Underwriters in connection with the transactions contemplated by this Agreement (excluding the fees and disbursements of Milbank LLP as counsel for the Underwriters); and

(xi) except as otherwise provided in the foregoing clauses (i) through (x), all other expenses incidental to the performance of the Company’s obligations under this Agreement, other than pursuant to Section 6.

11. Notices.

WHEREAS, the Basic Agreement, unlimited as to the aggregate face amount of Certificates (unless otherwise specified herein, capitalized terms used herein without definition having the respective meanings specified in the Basic Agreement) which may be issued thereunder, has heretofore been executed and delivered;

Section 1.01. The Certificates. There is hereby created a series of Certificates to be issued under the Agreement to be distinguished and known as “United Airlines Pass Through Certificates, Series 2020-1B” (hereinafter defined as the “Applicable Certificates”).

of certain of the pertinent provisions of which is set forth below. To the extent not otherwise defined herein, the capitalized terms used herein have the meanings assigned to them in the Agreement. This Certificate is one of the duly authorized Certificates designated as “United Airlines Pass Through Certificates, Series 2020-1B” (herein called the “Certificates”). This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement. By virtue of its acceptance hereof, the holder of this Certificate (the “Certificateholder” and, together with all other holders of Certificates issued by the Trust, the “Certificateholders”) assents to and agrees to be bound by the provisions of the Agreement and the Intercreditor Agreement. The property of the Trust includes a Series B Equipment Note and all rights of the Trust to receive payments under the Intercreditor Agreement and the Liquidity Facilities (the “Trust Property”). The Series B Equipment Note is secured by, among other things, a security interest in the Collateral.

The Certificates represent Fractional Undivided Interests in the Trust and the Trust Property and have no rights, benefits or interest in respect of any other separate trust established pursuant to the terms of the Basic Agreement for any other series of certificates issued pursuant thereto.

Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, from funds then available to the Trustee, there will be distributed on January 15, April 15, July 15 and October 15 of each year (a “Regular Distribution Date”) commencing April 15, 2021, to the Person in whose name this Certificate is registered at the close of business on the 15th day preceding the Regular Distribution Date, an amount in respect of the Scheduled Payments on the Series B Equipment Note due on such Regular Distribution Date, the receipt of which has been confirmed by the Trustee, equal to the product of the percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Scheduled Payments. Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, in the event that Special Payments on the Series B Equipment Note are received by the Trustee, from funds then available to the Trustee, there shall be distributed on the applicable Special Distribution Date, to the Person in whose name this Certificate is registered at the close of business on the 15th day preceding the Special Distribution Date, an amount in respect of such Special Payments on the Series B Equipment Note, the receipt of which has been confirmed by the Trustee, equal to the product of the percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Special Payments so received. If a Regular Distribution Date or Special Distribution Date is not a Business Day, distribution shall be made on the immediately following Business Day with the same force and effect as if made on such Regular Distribution Date or Special Distribution Date and no interest shall accrue during the intervening period. The Trustee shall mail notice of each Special Payment and the Special Distribution Date therefor to the Certificateholder of this Certificate.

Distributions on this Certificate will be made by the Trustee by check mailed to the Person entitled thereto, without presentation or surrender of this Certificate or the making of any notation hereon, except that with respect to Certificates registered on the Record Date in the name of a Clearing Agency (or its nominee) such distribution shall be made by wire transfer. Except as otherwise provided in the Agreement and notwithstanding the above, the final distribution on this Certificate will be made after notice mailed by the Trustee of the pendency of

A-3

such distribution and only upon presentation and surrender of this Certificate at the office or agency of the Trustee specified in such notice.

The Certificates do not represent a direct obligation of, or an obligation guaranteed by, or an interest in, the Company or the Trustee or any affiliate thereof. The Certificates are limited in right of payment, all as more specifically set forth on the face hereof and in the Agreement. All payments or distributions made to Certificateholders under the Agreement shall be made only from the Trust Property and only to the extent that the Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of the Agreement. Each Certificateholder of this Certificate, by its acceptance hereof, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for distribution to such Certificateholder as provided in the Agreement. This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for information with respect to the interests, rights, benefits, obligations, privileges, and duties evidenced hereby. A copy of the Agreement may be examined during normal business hours at the principal office of the Trustee, and at such other places, if any, designated by the Trustee, by any Certificateholder upon request.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Certificateholders under the Agreement at any time by the Company and the Trustee with the consent of the Certificateholders holding Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Trust. Any such consent by the Certificateholder of this Certificate shall be conclusive and binding on such Certificateholder and upon all future Certificateholders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Certificateholders of any of the Certificates.

As provided in the Agreement and subject to certain limitations set forth therein, the transfer of this Certificate is registrable in the Register upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee in its capacity as Registrar, or by any successor Registrar, duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar, duly executed by the Certificateholder hereof or such Certificateholder’s attorney duly authorized in writing, and thereupon one or more new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in minimum denominations of $1,000 Fractional Undivided Interest and integral multiples thereof, except that one Certificate may be issued in a different denomination. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust, as requested by the Certificateholder surrendering the same.

A-4

No service charge will be made for any such registration of transfer or exchange, but the Trustee shall require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith.

Each Certificateholder and Investor, by its acceptance of this Certificate or a beneficial interest herein, agrees to treat the Trust as a grantor trust for all U.S. federal, state and local income tax purposes.

The Trustee, the Registrar, and any agent of the Trustee or the Registrar may treat the person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Trustee, the Registrar, nor any such agent shall be affected by any notice to the contrary.

The obligations and responsibilities created by the Agreement and the Trust created thereby shall terminate upon the distribution to Certificateholders of all amounts required to be distributed to them pursuant to the Agreement and the disposition of all property held as part of the Trust Property.

Any Person acquiring or accepting this Certificate or an interest herein will, by such acquisition or acceptance, be deemed to have represented and warranted to and for the benefit of the Company that either: (i) no assets of an employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), a plan subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or a governmental, church or foreign plan subject to a law that is similar to Title I of ERISA or Section 4975 of the Code (a “Similar Law Plan”) have been used to purchase or hold this Certificate or an interest herein or (ii) the purchase and holding of this Certificate or an interest herein either (a) in the case of assets of an employee benefit plan subject to Title I of ERISA or a plan subject to Section 4975 of the Code, are exempt from the prohibited transaction restrictions of ERISA and the Code pursuant to one or more prohibited transaction statutory or administrative exemptions or (b) in the case of assets of a Similar Law Plan, will not violate any similar state, local or foreign law.

If the purchaser or transferee of this Certificate or an interest herein is an employee benefit plan subject to Title I of ERISA or a plan subject to Section 4975 of the Code, it will be deemed to represent, warrant and agree that (i) none of United Airlines Holdings, Inc., the Company, or the Underwriters, nor any of their affiliates, has provided any investment recommendation or investment advice on which it, or any fiduciary or other person investing the assets of such plan (“Plan Fiduciary”), has relied in connection with its decision to invest in this Certificate, and they are not otherwise acting as a fiduciary, as defined in Section 3(21) of ERISA or Section 4975(e)(3) of the Code, to such plan or the Plan Fiduciary in connection with such plan’s acquisition of this Certificate; and (ii) the Plan Fiduciary is exercising its own independent judgment in evaluating the transaction.

THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF

Each Notice of Borrowing shall be effective upon receipt of a copy thereof by the Liquidity Provider at the address specified pursuant to Section 7.02.

(e) Upon the making of any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower’s payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c), (d) or (g) hereof to fund the Class B Cash Collateral Account relating to this Liquidity Facility, the Liquidity Provider shall have no interest in or rights to such Class B Cash Collateral Account, the funds constituting such Advance or any other amounts from time to time on deposit in such Class B Cash Collateral Account; provided that the foregoing shall not affect or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.5(e) or (f) of the Intercreditor Agreement, and provided, further, that the foregoing shall not affect or impair the rights of the Liquidity Provider to provide written instructions with respect to the investment and reinvestment of amounts in such Class B Cash Collateral Account to the extent provided in Section 2.2(b) of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity

[Revolving Credit Agreement (2020-1B)]

Provider makes no representation as to, and assumes no responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested.

(f) A Special Termination Advance shall be made in a single Borrowing upon the receipt by the Borrower of a Special Termination Notice from the Liquidity Provider pursuant to Section 6.02, by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex VII, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account relating to this Liquidity Facility (in accordance with Section 3.5(f) and Section 3.5(m) of the Intercreditor Agreement).

Section 2.03 Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the Fee Letter applicable to this Agreement, to the extent payable to the Liquidity Provider pursuant to such Fee Letter.

Section 2.04 Reductions or Termination of the Maximum Commitment.

(a) Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance of the Class B Certificates or otherwise, the Maximum Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower); provided that on (or, as applicable, immediately following) the first Regular Distribution Date, the Maximum Commitment shall automatically be reduced to the then Required Amount. The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment.

(b) Termination. Upon the making of any Provider Advance or Special Termination Advance or the making of or conversion to a Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to request any further Borrowing hereunder, except in the case of a Downgrade Advance, as provided in Section 2.06(d).

Section 2.05 Repayments of Interest Advances, the Special Termination Advance or the Final Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to pay, or to cause to be paid, to the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance, the Special Termination Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is referred to herein as an “Unpaid Advance”) (if multiple Interest Advances are outstanding any such repayment to be applied in the order in which such Interest Advances have been made, starting with the earliest), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which shall not have been repaid in accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time

[Revolving Credit Agreement (2020-1B)]

when unreimbursed Interest Advances have reduced the Maximum Available Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or an Applied Non-Extension Advance, as the case may be, for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for the purposes of Section 2.06(b)); provided, further, that amounts in respect of a Special Termination Advance withdrawn from the Class B Cash Collateral Account relating to this Liquidity Facility for the purpose of paying interest on the Class B Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being an “Applied Special Termination Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; provided, further, that if, following the making of a Special Termination Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01, such Special Termination Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and treated as an Applied Special Termination Advance for purposes of Section 2.6(c) of the Intercreditor Agreement, and, provided, further, that if, after making a Provider Advance, the Liquidity Provider delivers a Special Termination Notice to the Borrower pursuant to Section 6.02, any Unapplied Provider Advance shall be converted to and treated as a Special Termination Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof under the Intercreditor Agreement. The Borrower and the Liquidity Provider agree that the repayment in full of each Interest Advance, the Special Termination Advance and the Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider.

Section 2.06 Repayments of Provider Advances.

(a) Amounts advanced hereunder in respect of a Provider Advance shall be deposited in the Class B Cash Collateral Account relating to this Liquidity Facility, invested and withdrawn from such Class B Cash Collateral Account as set forth in Sections 3.5(c), (d), (e) and (f) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09, the Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class B Cash Collateral Account relating to this Liquidity Facility for the purpose of paying interest on the Class B Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being (y) in the case of a Downgrade Advance, an “Applied Downgrade Advance” and (z) in the case of a Non-Extension Advance, an “Applied Non-Extension Advance” and, together with an Applied Downgrade Advance, an “Applied Provider Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the dates on which such interest is payable; provided, further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to

[Revolving Credit Agreement (2020-1B)]

Section 6.01 hereof, such Provider Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and treated as an Applied Downgrade Advance or Applied Non-Extension Advance, as the case may be, for the purposes of Section 2.6(c) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class B Cash Collateral Account relating to this Liquidity Facility on account of a reduction in the Required Amount, the Borrower shall repay to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to the amount of such reduction, plus interest on the principal amount prepaid as provided in Section 3.07 hereof.

(b) At any time when an Applied Provider Advance or an Applied Special Termination Advance (or any portion thereof) is outstanding, upon the deposit in the Class B Cash Collateral Account relating to this Liquidity Facility of any amount pursuant to clause “fourth” of Section 3.2 of the Intercreditor Agreement (any such amount being a “Replenishment Amount”) for the purpose of replenishing or increasing the balance thereof up to the amount of the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances or the Applied Special Termination Advance (and of Provider Advances treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount (if multiple Applied Provider Advances are outstanding, such Replenishment Amount to be applied in the order in which such Applied Provider Advances have been made, starting with the earliest) and (ii) the aggregate outstanding principal amount of all Unapplied Provider Advances or of the Unapplied Special Termination Advance shall be automatically increased by the amount of such Replenishment Amount.

(c) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.5(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class B Cash Collateral Account relating to this Liquidity Facility after giving effect to any Applied Provider Advance or Applied Special Termination Advance on the date of such replacement shall be reimbursed to the replaced Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the replaced Liquidity Provider all amounts owing to it hereunder.

(d) If, at any time after making a Downgrade Advance, the Liquidity Provider satisfies the Threshold Rating and delivers a written notice to that effect to the Borrower and United, as of the second Business Day following receipt of such notice, (i) the Unapplied Downgrade Advance shall be withdrawn from the Class B Cash Collateral Account relating to this Liquidity Facility and reimbursed to the Liquidity Provider, (ii) the Maximum Commitment shall be reinstated by an amount equal to the amount of such Unapplied Downgrade Advance so reimbursed, but not to exceed the Maximum Commitment and the obligation of the Liquidity Provider to make Advances shall be reinstated in an equal amount, and (iii) the proviso in the definition of Maximum Available Commitment shall no longer apply to such Downgrade Advance.

Section 2.07 Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for payment or repayment to the Liquidity Provider of any amounts hereunder,

[Revolving Credit Agreement (2020-1B)]

the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.5(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so paid to, and not required to be returned by, the Liquidity Provider shall be applied by the Liquidity Provider to Liquidity Obligations then due and payable to it in accordance with the Intercreditor Agreement and shall discharge in full the corresponding obligations of the Borrower hereunder (or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate).

Section 2.08 Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided, however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances.

Section 2.09 Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement, including, without limitation, Sections 7.05 and 7.07, shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under Section 8.1 of the Note Purchase Agreement and payments under the Fee Letter applicable to this Agreement and Section 6 of the Note Purchase Agreement and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts in respect of payments to be made by the Borrower hereunder to the extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except as expressly provided in this Agreement, the Intercreditor Agreement or the Note Purchase Agreement. Amounts on deposit in the Class B Cash Collateral Account relating to this Liquidity Facility shall be available to the Borrower to make payments under this Agreement only to the extent and for the purposes expressly contemplated in Section 3.5(f) of the Intercreditor Agreement.

Section 2.10 Non-Extension of the Expiry Date; Non-Extension Advance. If in any calendar year the Liquidity Provider advises the Borrower before the 25^th day prior to the anniversary date of the Class B Closing Date in such calendar year (such 25^th day, the “Notice Date”) that the Expiry Date shall not be extended beyond such anniversary date (and if this Agreement shall not have been replaced in accordance with Section 3.5(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after such Notice Date (but prior to the then effective Expiry Date) to request a Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.5(d) of the Intercreditor Agreement; provided, however, that if in any calendar year the Liquidity Provider does not so advise the Borrower before the Notice Date in such calendar year, the Expiry Date shall be automatically extended to the anniversary date of the Class B Closing Date in the next calendar year.

Section 2.11 LIBOR Replacement.

[Revolving Credit Agreement (2020-1B)]

(a) Benchmark Replacement. Notwithstanding anything to the contrary herein, if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to each applicable party hereto (that is not then the Designated Party) without any amendment to, or further action or consent of any other party to, this Agreement.

(b) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Designated Party will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

(c) Notices; Standards for Decisions and Determinations. The Designated Party will promptly notify each other party hereto (and each other “Liquidity Provider” under each other Liquidity Facility) of (i) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, (iv) the removal or reinstatement of any tenor of a Benchmark pursuant to clause (d) below and (v) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Designated Party pursuant to this 2.11, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement except, in each case, as expressly required pursuant to this Section 2.11 (and the definitions used herein).

[Revolving Credit Agreement (2020-1B)]

Liquidity Facilities for which it is the “Designated Party”) the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Designated Party may (and shall at the request of the Liquidity Provider) modify (in a manner consistent for all Liquidity Facilities for which it is the “Designated Party”) the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of (or any determination by the Designated Party as to the existence of) a Benchmark Unavailability Period, the Borrower may revoke any request for a conversion to or continuation of a LIBOR Advance to be converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to a Base Rate Advance.

(f) Cap on Benchmark for any Interest Period. Anything herein to the contrary notwithstanding, in connection with any Benchmark Replacement and the resulting Benchmark and related Benchmark Replacement Conforming Changes, if for any Interest Period (as such term may be modified) or Available Tenor, the applicable Benchmark Replacement (as the Benchmark then in effect) would exceed, as of the applicable date of determination thereof (including any applicable Reference Time) the Base Rate, then the Benchmark Replacement (and Benchmark) for such Interest Period or Available Tenor, as the case may be, shall be deemed to be the Base Rate.

(g) Consistent Implementation among Liquidity Facilities. In making determinations pursuant to this Section 2.11 (and implementing any Benchmark Replacement and Benchmark Conforming Changes in connection therewith), it is the intent of the parties that such determinations (and implementation) occur hereunder on or about the same time and in substantially the same manner as such determinations (and implementation) pursuant to Section 2.11 of each other Liquidity Facility for which the Designated Party hereunder is the “Designated Party”, and the parties will reasonably cooperate for achieving such result.

article III

OBLIGATIONS OF THE BORROWER

[Revolving Credit Agreement (2020-1B)]

laws or regulations (including Regulation D of the Board of Governors of the Federal Reserve System), or the adoption or making after the date of this Agreement of any interpretations, directives, or requirements applying to a class of banks including the Liquidity Provider under any U.S. federal, state, municipal, or any foreign laws or regulations (whether or not having the force of law) by any court, central bank or monetary authority charged with the interpretation or administration thereof (a “Regulatory Change”), which: (1) changes the basis of taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances or such obligation (other than Excluded Taxes); or (2) imposes or modifies any reserve, special deposit, compulsory loan or similar requirements relating to any extensions of credit or other assets of, or any deposits with other liabilities of, the Liquidity Provider (including any such Advances or such obligation or any deposits referred to in the definition of LIBOR Rate or related definitions). For the avoidance of doubt, any Regulatory Changes based on the consultative papers of The Basel Committee on Banking Supervision of December 2009 entitled “Strengthening the resilience of the banking sector” and “International framework for liquidity risk measurement, standards and monitoring”, in each case together with any amendments thereto (collectively, “Basel III”), will not be treated, for purposes of determining whether the Liquidity Provider is entitled to compensation under this Section 3.01, as having been adopted or having come into effect before the date hereof, and any such Regulatory Changes based on Basel III shall be determined to be adopted only when the national banking supervisory authorities, or other relevant administrative or legislative bodies having primary jurisdiction or regulatory authority over the Liquidity Provider, adopt any such Regulatory Changes based on Basel III in the primary jurisdiction of the Liquidity Provider. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section.

Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination Agent agree that any Liquidity Provider, or permitted assignee or participant thereof, which is not a bank shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof).

[Revolving Credit Agreement (2020-1B)]

with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider with any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in clause (2), has the effect of (x) requiring an increase in the amount of capital or liquid assets required to be maintained by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider, or (y) reducing the rate of return on assets or capital of the Liquidity Provider (or such corporation or bank) and such adoption, change or compliance, as the case may be, relates to a category of claims or assets that includes the Liquidity Provider’s obligations hereunder (including funded obligations) and other similar obligations, the Borrower shall, subject to the provisions of the next paragraph, pay to the Liquidity Provider from time to time such additional amount or amounts as are necessary to compensate the Liquidity Provider for such portion of such increase or reduction as shall be reasonably allocable to the Liquidity Provider’s obligations to the Borrower hereunder. For the avoidance of doubt, the adoption of any law, rule or regulation described in clause (1) of the first sentence of this Section 3.02, and the taking of any action described in clauses (2) and (3) of such sentence, that in each case is based on Basel III, will not be treated, for purposes of determining whether the Liquidity Provider (or any corporation or bank controlling the Liquidity Provider) is entitled to compensation under this Section 3.02, as having been adopted, come into effect, been issued or been taken before the date hereof, and any such law, rule or regulation and any of the actions described in clauses (2) and (3) of such sentence that is based on Basel III shall be determined to have been adopted, come into effect, been issued or been taken only when the central bank or other legislative or administrative governmental authorities in the primary jurisdiction of the Liquidity Provider (or any corporation or bank controlling the Liquidity Provider) adopt any such law, rule or regulation or take any such actions. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise materially disadvantageous to the Liquidity Provider.

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital or liquid assets required to be maintained by the Liquidity Provider and of the amount allocable to the Liquidity Provider’s obligations to the Borrower hereunder shall be conclusive evidence of the amounts owed under this Section, absent manifest error.

Section 3.03 Payments Free of Deductions.

[Revolving Credit Agreement (2020-1B)]

(a) Unless required by applicable law, all payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever now or hereafter imposed on, levied, collected, withheld or assessed, excluding Excluded Taxes (such non-excluded taxes being referred to herein, collectively, as “Non-Excluded Taxes” and each, individually, as a “Non-Excluded Tax”). If any Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, (i) the Borrower shall within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Non-Excluded Taxes (and any additional Non-Excluded Taxes in respect of the additional amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) the amounts so payable to the Liquidity Provider shall be increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower two original Internal Revenue Service Forms W-8BEN-E, W-8ECI or W-9, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement. Within 30 days after the date of each payment hereunder, the Borrower shall furnish to the Liquidity Provider the original or a certified copy of (or other documentary evidence of) the payment of the Non-Excluded Taxes applicable to such payment.

(b) Unless required by applicable law, all payments (including, without limitation, Advances) made by the Liquidity Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes) will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to the Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment.

[Revolving Credit Agreement (2020-1B)]

reasonably available to the Borrower without providing any information regarding the holders or beneficial owners of the Certificates, the Borrower shall deliver to the Liquidity Provider such form or forms and such other evidence of the eligibility of the Borrower for such exemption or reductions (but without any requirement to provide any information regarding the holders or beneficial owners of the Certificates) as the Liquidity Provider may reasonably identify to the Borrower as being required as a condition to exemption from, or reduction in the rate of, such Taxes.

(d) If a payment made to the Liquidity Provider or Borrower hereunder would be subject to U.S. federal withholding Tax imposed by FATCA if the Borrower or Liquidity Provider, as applicable, were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471 (b) or 1472 (b) of the U.S. Internal Revenue Code, as applicable), it shall deliver to the Borrower or the Liquidity Provider, as applicable, at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or Liquidity Provider, as applicable, such documentation prescribed by applicable law (including as prescribed by Section 1471 (b)(3)(C)(i) of the U.S. Internal Revenue Code) and such additional documentation reasonably requested by the Borrower or Liquidity Provider, as applicable, as may be necessary for the Borrower or Liquidity Provider, as applicable, to comply with its obligations under FATCA and to determine that the Liquidity Provider or Borrower has complied with the Liquidity Provider’s or Borrower’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this paragraph, “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Section 3.04 Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 p.m. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America, to the Liquidity Provider in immediately available funds, by wire transfer to the account specified for the Liquidity Provider in Schedule B or to such other U.S. bank account as the Liquidity Provider may from time to time direct the Borrower in writing.

Section 3.05 Computations. All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate (other than where the LIBOR Rate is determined based on the Base Rate or any Benchmark Replacement with determinations based on a year of 365 or 366 days, as the case may be) shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 3.06 Payment on Non-Business Days. Whenever any payment to be made hereunder to the Liquidity Provider shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and no additional interest shall be due as a result. If any payment in respect of interest on an Advance is so deferred to the next succeeding Business Day, such deferral shall not delay the commencement of the next Interest Period for such Advance (if such Advance is a LIBOR Advance) or reduce the number of days for which interest will be payable on such Advance on the next interest payment date for such Advance.

[Revolving Credit Agreement (2020-1B)]

Section 3.07 Interest.

(a) Subject to Section 2.09, the Borrower shall pay, or shall cause to be paid, without duplication, interest on (i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, from and including the date on which the amount thereof was withdrawn from the Class B Cash Collateral Account relating to this Liquidity Facility to pay interest on the Class B Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, the date on which the Class B Cash Collateral Account relating to this Liquidity Facility is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount, as the case may be, as in effect for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07 shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until the total amount of interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect.

(b) Except as provided in clause (e) below, each Advance will be either a Base Rate Advance or a LIBOR Advance as provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its Borrowing to (but excluding) the third LIBOR Business Day following the Liquidity Provider’s receipt of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance.

(c) Each LIBOR Advance shall bear interest during each Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

(d) Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of interest accrued on the amount of principal repaid).

[Revolving Credit Agreement (2020-1B)]

Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance, as applicable, on the amount of such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance, as applicable, from time to time, payable in arrears on each Regular Distribution Date.

(f) Each amount not paid when due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by applicable law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% per annum until paid.

(g) If at any time, the Liquidity Provider shall have determined (which determination shall be conclusive and binding upon the Borrower, absent manifest error) that, by reason of circumstances affecting the relevant interbank lending market generally (other than a Benchmark Transition Event), the LIBOR Rate determined or to be determined for the current or the immediately succeeding Interest Period will not adequately and fairly reflect the cost to the Liquidity Provider (as conclusively certified by the Liquidity Provider, absent manifest error) of making or maintaining LIBOR Advances, the Liquidity Provider shall give facsimile or telephonic notice thereof (a “Rate Determination Notice”) to the Borrower (any such telephonic notice to be promptly confirmed in writing and transmitted by telecopier to the Borrower in accordance with Section 7.02). If such notice is given, then the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances effective from the date of the Rate Determination Notice; provided that the Applicable Liquidity Rate in respect of such Base Rate Advances shall be increased by one percent (1.00%). The Liquidity Provider shall withdraw a Rate Determination Notice given hereunder when the Liquidity Provider determines that the circumstances giving rise to such Rate Determination Notice no longer apply to the Liquidity Provider, and the Base Rate Advances shall be converted to LIBOR Advances effective as of the first day of the next succeeding Interest Period after the date of such withdrawal.

(h) Each change in the Base Rate shall become effective immediately. The rates of interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the “Applicable Liquidity Rate”.

Section 3.08 Replacement of Borrower. From time to time and subject to the successor Borrower’s meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent in substantially the form of Annex VI attached hereto (a “Notice of Replacement Subordination Agent”) delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted for the Borrower for all purposes hereunder.

Section 3.09 Funding Loss Indemnification. The Borrower shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of:

[Revolving Credit Agreement (2020-1B)]

(1) Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such Advance; or

(2) Any failure by the Borrower to borrow a LIBOR Advance on the date for borrowing specified in the relevant notice under Section 2.02.

Calculation of all amounts payable to the Liquidity Provider under this Section 3.09 shall be made as though the Liquidity Provider had actually funded the related LIBOR Advance through the purchase of a LIBOR deposit bearing interest at the LIBOR Rate in an amount equal to its LIBOR Advance and having a maturity comparable to the relevant Interest Period; provided, however, that the Liquidity Provider may fund any LIBOR Advance in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 3.09.

Section 3.10 Illegality. Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Facility Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the Liquidity Provider (or its Facility Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the last Interest Period to expire before the effective date of any such change or request. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid or cure the aforesaid illegality and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

[Revolving Credit Agreement (2020-1B)]

whether documents presented hereunder comply with the terms hereof, or (B) any breach by the Liquidity Provider of any of the terms of this Agreement, including, but not limited to, the Liquidity Provider’s failure to make lawful payment hereunder after the delivery to it by the Borrower of a Notice of Borrowing strictly complying with the terms and conditions hereof. In no event, however, shall the Liquidity Provider be liable on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings).

(b) Neither the Liquidity Provider nor any of its officers, employees, directors or Affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or gross negligence (in which event the extent of the Liquidity Provider’s potential liability to the Borrower shall be limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing.

Section 7.07 Costs, Expenses and Taxes. The Borrower agrees, subject to the Fee Letter to the extent applicable, to pay, or cause to be paid (A) on the Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket costs and expenses (including, without limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and recording of this Agreement, any other Operative Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses (including reasonable counsel fees and expenses) of the Liquidity Provider in connection with (i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such other documents which may be delivered in connection herewith or therewith (whether or not the same shall become effective) or any waiver or consent thereunder (whether or not the same shall be effective), (iii) the replacement of this Agreement by a Replacement Liquidity Facility pursuant to Section 3.5(e)(i) of the Intercreditor Agreement or (iv) any action or proceeding relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting the application of funds in the Class B Cash Collateral Account relating to this Liquidity Facility. In addition, the Borrower shall pay any and all recording, stamp and other similar taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to hold the Liquidity Provider harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees. Notwithstanding the foregoing, any obligation of the Borrower (or United) to reimburse or pay fees of counsel for the Liquidity Provider (pursuant to this Section 7.07 or any other applicable provision of the Operative Agreements) shall be based on (and limited to) one counsel for all “Liquidity Providers” for the Class B Certificates (and, (i) in the case of any conflict of interest (excluding for avoidance of doubt any conflicts, and any reimbursement for legal fees, attributable to transfers between, or separate agreements or claims between or among, any such “Liquidity Providers”), up to one additional counsel for all

[Revolving Credit Agreement (2020-1B)]

affected “Liquidity Providers”, and (ii) one Federal Aviation Administration counsel and/or local counsel in any relevant jurisdiction), as selected by the applicable such “Liquidity Provider” (as among the relevant such “Liquidity Providers” so having the right to select such counsel) having the highest outstanding aggregate amount of Liquidity Obligations (taking into account all Liquidity Facilities for Class B Certificates) or as may otherwise be agreed as among such “Liquidity Providers” in respect of such selection.

Section 7.08 Binding Effect; Participations; Assignments.

(a) This Agreement shall be binding upon and inure to the benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08 and in Section 3.5(l) of the Intercreditor Agreement) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the other Operative Agreements to such Persons (other than United and its Affiliates) as the Liquidity Provider may in its sole discretion select, subject to the requirements of Section 7.08(b). No such granting of participations by the Liquidity Provider, however, will relieve the Liquidity Provider of its obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider’s source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative Agreements to determinations, reserve, capital adequacy and liquidity coverage requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03 and the like as they pertain to the Liquidity Provider shall be deemed also to include those of each of its participants that are banks (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the participant, had held the interest participated).

(b) If the Liquidity Provider sells any participation in this Agreement pursuant to subsection (a) above to any bank or other entity (each, a “Transferee”), then, concurrently with the effectiveness of such participation, the Transferee shall (i) represent to the Liquidity Provider (for the benefit of the Liquidity Provider and the Borrower) either (A) that it is incorporated under the laws of the United States or a state thereof or (B) that under applicable law and treaties, no taxes will be required to be withheld with respect to any payments to be made to such Transferee in respect of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) if it is incorporated under the laws of the United States or a state thereof, a Form W-9 or (y) if it is not so incorporated, two copies of a properly completed United States Internal Revenue Service Form W-8ECI, or Form W-8BEN-E, as appropriate, or other applicable form, certificate or document prescribed by the Internal Revenue Service certifying, in each case, such Transferee’s entitlement to a complete exemption from United States federal withholding tax in respect to any and all payments to be made hereunder, and (iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide the Liquidity Provider and the Borrower a new

[Revolving Credit Agreement (2020-1B)]

Form W-8ECI, Form W-8BEN-E or Form W-9, as appropriate, (A) on or before the date that any such form expires or becomes obsolete or (B) after the occurrence of any event requiring a change in the most recent form previously delivered by it and prior to the immediately following due date of any payment by the Borrower hereunder, certifying in the case of a Form W-8ECI, Form W-8BEN-E or Form W-9 that such Transferee is entitled to a complete exemption from United States federal withholding tax on payments under this Agreement. Unless the Borrower has received forms or other documents reasonably satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

(c) Notwithstanding the other provisions of this Section 7.08, the Liquidity Provider may assign and pledge all or any portion of the Advances owing to it to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank, provided that any payment in respect of such assigned Advances made by the Borrower to the Liquidity Provider in accordance with the terms of this Agreement shall satisfy the Borrower’s obligations hereunder in respect of such assigned Advance to the extent of such payment. No such assignment shall release the Liquidity Provider from its obligations hereunder.

Section 7.09 Severability. Any provision of this Agreement which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or non-authorization without invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

form of mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider shall have been notified pursuant thereto; and

(iv) 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.

The Borrower and the Liquidity Provider each warrant and represent that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. 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 the 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, the 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 7.12 Execution in Counterparts; Electronic Transmission; Electronic Execution. This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or in electronic (e.g., “pdf” or “tif”) format shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,” “signature,” and words of like import in this Agreement and the Fee Letter shall be deemed to include electronic signatures or electronic records, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.
