Upon the payment in full by Owner of any indemnity provided for under this Agreement, Owner, without any further action and to the full extent permitted by Law, will be subrogated to all rights and remedies of the person indemnified (other than with respect to any of such Indemnitee’s insurance policies or in connection with any indemnity claim such Indemnitee may have under Section 6.03 of the Trust Indenture) in respect of the matter as to which such indemnity was paid. Each Indemnitee will give such further assurances or agreements and cooperate with Owner to permit Owner to pursue such claims, if any, to the extent reasonably requested by Owner and at Owner’s expense.

(m) Taxes relating to ERISA or Section 4975 of the Code.

For purposes hereof, a Tax Indemnitee and any other Tax Indemnitees that are successors, assigns, agents, servants or Affiliates of such Tax Indemnitee shall be related Tax Indemnitees.

8.3.3. Payment

(a) Owner’s indemnity obligation to a Tax Indemnitee under this Section 8.3 shall equal the amount which, after taking into account any Tax imposed upon the receipt or accrual of the amounts payable under this Section 8.3 and any tax benefits actually recognized by such Tax Indemnitee as a result of the indemnifiable Tax (including, without limitation, any benefits recognized as a result of an indemnifiable Tax being utilized by such Tax Indemnitee as a credit against Taxes not indemnifiable under this Section 8.3), shall equal the amount of the Tax indemnifiable under this Section 8.3.

(b) At Owner’s request, the computation of the amount of any indemnity payment owed by Owner or any amount owed by a Tax Indemnitee to Owner pursuant to this Section 8.3 shall be verified and certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably satisfactory to Owner. Such verification shall be binding. The costs of such verification (including the fee of such public accounting firm) shall be borne by Owner unless such verification shall result in an adjustment in Owner’s favor of 5% or more of the net present value of the payment as computed by such Tax Indemnitee, in which case the costs shall be paid by such Tax Indemnitee.

(c) Each Tax Indemnitee shall provide Owner with such certifications, information and documentation as shall be in such Tax Indemnitee’s possession and as shall be reasonably requested by Owner to minimize any indemnity payment pursuant to this Section 8.3; provided, that notwithstanding anything to the contrary contained herein, no Tax Indemnitee shall be required to provide Owner with any Tax returns.

(d) Each Tax Indemnitee shall promptly forward to Owner any written notice, ▇▇▇▇ or advice received by it from any Taxing Authority concerning any Tax for which it seeks indemnification under this Section 8.3. Owner shall pay any amount for which it is liable pursuant to this Section 8.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in accordance with Section 8.3.4, within 30 days after a Final Determination (as defined below)), but in no event more than one Business Day prior to the date the Tax to which such amount payable hereunder relates is due. If requested by a Tax Indemnitee in writing, Owner shall furnish to the appropriate Tax Indemnitee the original or a certified copy of a receipt for Owner’s payment of any Tax paid by Owner or such other evidence of payment of such Tax as is acceptable to such Tax Indemnitee. Owner shall also furnish promptly upon written request such data as any Tax Indemnitee may reasonably require to enable such Tax Indemnitee to comply with the requirements of any taxing jurisdiction unless such data is not reasonably available to the Owner or, unless such data is specifically requested by a Taxing Authority, is not customarily furnished by domestic air carriers under similar circumstances. For purposes of this Section 8.3, a “Final Determination” shall mean (i) a decision, judgment, decree or other order by any court of competent jurisdiction that occurs pursuant to the provisions of Section 8.3.4, which decision, judgment, decree or other order has become final and unappealable, (ii) a closing agreement or settlement agreement entered into in accordance with Section 8.3.4 that has become binding and is not subject to further review or appeal (absent fraud, misrepresentation, etc.), or (iii) the termination of administrative proceedings and the expiration of the time for instituting a claim in a court proceeding.

(e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or indemnified by Owner pursuant to this Section 8.3 (whether such tax savings shall be by means of a foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not otherwise taken into account in computing such payment or indemnity such Tax Indemnitee shall pay to Owner an amount equal to the lesser of (i) the amount of such tax savings, plus any additional tax savings recognized as the result of any payment made pursuant to this sentence, when, as, if, and to the extent, realized or (ii) the amount of all payments pursuant to this Section 8.3 by Owner to such Tax Indemnitee (less any payments previously made by such Tax Indemnitee to Owner pursuant to this Section 8.3.3 (e)) (and the excess, if

any, of the amount described in clause (i) over the amount described in clause (ii) shall be carried forward and applied to reduce pro tanto any subsequent obligations of the Owner to make payments to such Tax Indemnitee pursuant to this Section 8.3); provided, that such Tax Indemnitee shall not be required to make any payment pursuant to this sentence so long as an Event of Default of a monetary nature has occurred and is continuing. If a tax benefit is later disallowed or denied, the disallowance or denial shall be treated as a Tax indemnifiable under Section 8.3.1 without regard to the provisions of Section 8.3.2 (other than Section 8.3.2 (f)). Each such Tax Indemnitee shall in good faith use reasonable efforts in filing its tax returns and in dealing with Taxing Authorities to seek and claim any such tax benefit.

8.3.4. Contest

(a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Owner could be liable for payment or indemnity hereunder, or if a Tax Indemnitee makes a determination that a Tax is due for which Owner could have an indemnity obligation hereunder, such Tax Indemnitee shall promptly give Owner notice in writing of such claim (provided, that failure to so notify Owner shall not relieve Owner of its indemnity obligations hereunder unless such failure to notify effectively forecloses Owner’s rights to require a contest of such claim) and shall take no action with respect to such claim without the prior written consent of Owner for 30 days following the receipt of such notice by Owner; provided, that, in the case of a claim made against a Tax Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such 30-day period, such Tax Indemnitee shall, in such notice to Owner, so inform Owner, and such Tax Indemnitee shall take no action for as long as it is legally able to do so (it being understood that a Tax Indemnitee shall be entitled to pay the Tax claimed and ▇▇▇ for a refund prior to the end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial penalties (unless immediately reimbursed by Owner) and the act of paying the Tax would not materially prejudice the right to contest or (B) the failure to so pay would result in criminal penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In addition, such Tax Indemnitee shall (provided, that Owner shall have agreed to keep such information confidential other than to the extent necessary in order to contest the claim) furnish Owner with copies of any requests for information from any Taxing Authority relating to such Taxes with respect to which Owner may be required to indemnify hereunder. If requested by Owner in writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at the expense of Owner (including, without limitation, all reasonable costs, expenses and reasonable attorneys’ and accountants’ fees and disbursements), in good faith contest (or, if permitted by applicable law, allow Owner to contest) through appropriate administrative and judicial proceedings the validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying the same except under protest if protest is necessary and proper or (III) if the payment is made, using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or judicial proceeding. If requested to do so by Owner, the Tax Indemnitee shall appeal any adverse administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue any appeals to the United States Supreme Court. If and to the extent the Tax Indemnitee is able to separate the contested issue or issues from other issues arising in the same administrative or judicial proceeding that are unrelated to the transactions contemplated by the Operative Agreements without, in the good faith judgment of such Tax Indemnitee, adversely affecting such Tax Indemnitee, such Tax Indemnitee shall

permit Owner to control the conduct of any such proceeding and shall provide to the Owner (at Owner’s cost and expense) with such information or data that is in such Tax Indemnitee’s control or possession that is reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax Indemnitee, such Tax Indemnitee shall consult with Owner in good faith regarding the manner of contesting such claim and shall keep Owner reasonably informed regarding the progress of such contest. A Tax Indemnitee shall not fail to take any action expressly required by this Section 8.3.4 (including, without limitation, any action regarding any appeal of an adverse determination with respect to any claim) or settle or compromise any claim without the prior written consent of the Owner (except as contemplated by Section 8.3.4(b) or (c)).

(b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue any contest (or to permit Owner to pursue any contest) unless (i) Owner shall have agreed to pay such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in connection with contesting such Taxes, including, without limitation, all reasonable out of pocket costs and expenses and reasonable attorneys’ and accountants’ fees and disbursements, (ii) if such contest shall involve the payment of the claim, Owner shall advance the amount thereof (to the extent indemnified hereunder) plus interest, penalties and additions to tax with respect thereto that are required to be paid prior to the commencement of such contest on an interest-free after-Tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to the Owner any net realized tax benefits resulting from such advance including any tax benefits resulting from making such payment), (iii) such Tax Indemnitee shall have reasonably determined that the action to be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless Owner shall have made provisions to protect the interests of any such Tax Indemnitee in a manner reasonably satisfactory to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to notify Owner in writing promptly after it becomes aware of any such risk), (iv) no Event of Default shall have occurred and be continuing unless Owner has provided security for its obligations hereunder by advancing to such Tax Indemnitee before proceeding or continuing with such contest, the amount of the Tax being contested, plus any interest and penalties and an amount estimated in good faith by such Tax Indemnitee for expenses, and (v) prior to commencing any judicial action controlled by Owner, Owner shall have acknowledged its liability for such claim hereunder, provided that Owner shall not be bound by its acknowledgment if the Final Determination articulates conclusions of law and fact that demonstrate that Owner has no liability for the contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release, waive, compromise or settle any claim which may be indemnifiable by Owner pursuant to this Section 8.3 without the written permission of Owner, Owner’s obligation to indemnify such Tax Indemnitee with respect to such claim (and all directly related claims and claims based on the outcome of such claim) shall terminate, subject to Section 8.3.4(c), and subject to Section 8.3.4(c), such Tax Indemnitee shall repay to the Owner any amount previously paid or advanced to such Tax Indemnitee with respect to such claim, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax.

(c) Notwithstanding anything contained in this Section 8.3, a Tax Indemnitee will not be required to contest the imposition of any Tax and shall be permitted to settle or compromise any claim without Owner’s consent if such Tax Indemnitee (i) shall waive its right to indemnity under this Section 8.3 with respect to such Tax (and any directly related claim and

any claim the outcome of which is determined based upon the outcome of such claim), (ii) shall pay to the Owner any amount previously paid or advanced by Owner pursuant to this Section 8.3 with respect to such Tax, plus interest at the rate that would have been payable by the relevant Taxing Authority with respect to a refund of such Tax, and (iii) shall agree to discuss with Owner the views or positions of any relevant Taxing Authority with respect to the imposition of such Tax.

8.3.5. Refund

If any Tax Indemnitee shall receive a refund of, or be entitled to a credit against other liability for, all or any part of any Taxes paid, reimbursed or advanced by Owner, such Tax Indemnitee shall pay to Owner within 30 days of such receipt an amount equal to the lesser of (a) the amount of such refund or credit plus any net tax benefit (taking into account any Taxes incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee made pursuant to this sentence (including this clause (a)) and (b) such tax payment, reimbursement or advance by Owner to such Tax Indemnitee theretofore made pursuant to this Section 8.3 (and the excess, if any, of the amount described in clause (a) over the amount described in clause (b) shall be carried forward and applied to reduce pro tanto any subsequent obligation of Owner to make payments to such Tax Indemnitee pursuant to this Section 8.3). If, in addition to such refund or credit, such Tax Indemnitee shall receive (or be credited with) an amount representing interest on the amount of such refund or credit, such Tax Indemnitee shall pay to Owner within 30 days of such receipt or realization of such credit that proportion of such interest that shall be fairly attributable to Taxes paid, reimbursed or advanced by Owner prior to the receipt of such refund or realization of such credit.

8.3.6. Tax Filing

If any report, return or statement is required to be filed with respect to any Tax which is subject to indemnification under this Section 8.3, Owner shall timely file the same (except for any such report, return or statement which a Tax Indemnitee has timely notified the Owner in writing that such Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to file, in its own name); provided, that the relevant Tax Indemnitee shall furnish Owner with any information in such Tax Indemnitee’s possession or control that is reasonably necessary to file any such return, report or statement and is reasonably requested in writing by Owner (it being understood that the Tax Indemnitee shall not be required to furnish copies of its actual tax returns, although it may be required to furnish relevant information contained therein). Owner shall either file such report, return or statement and send a copy of such report, return or statement to such Tax Indemnitee, or, where Owner is not permitted to file such report, return or statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such report, return or statement to such Tax Indemnitee in a manner satisfactory to such Tax Indemnitee within a reasonable time prior to the time such report, return or statement is to be filed.

8.3.7. Forms

Each Tax Indemnitee agrees to furnish from time to time to the Owner or Mortgagee or to such other person as Owner or Mortgagee may designate, at Owner’s or Mortgagee’s request, such duly executed and properly completed forms as may be necessary or appropriate in order to claim any reduction of or exemption from any withholding or other Tax imposed by any Taxing Authority, if (x) such reduction or exemption is available to such Tax Indemnitee and (y) Owner has provided such Tax Indemnitee with any information necessary to complete such form not otherwise reasonably available to such Tax Indemnitee.

8.3.8. Non-Parties

If a Tax Indemnitee is not a party to this Agreement, Owner may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Owner, to the terms of this Section 8.3 and Section 12.8 prior to making any payment to such Tax Indemnitee under this Section 8.3.

8.3.9. Subrogation

Upon payment of any Tax by Owner pursuant to this Section 8.3 to or on behalf of a Tax Indemnitee, Owner, without any further action, shall be subrogated to any claims that such Tax Indemnitee may have relating thereto. Such Tax Indemnitee shall cooperate with Owner (to the extent such cooperation does not result in any unreimbursed cost, expense or liability to such Tax Indemnitee) to permit Owner to pursue such claims.

8.4. Payments

Any payments made pursuant to Section 8.1 or 8.3 shall be due on the 60th day after demand therefor and shall be made directly to the relevant Indemnitee or Tax Indemnitee or to Owner, in immediately available funds at such bank or to such account as specified by such Indemnitee or Tax Indemnitee or Owner, as the case may be, in written directives to the payor, or, if no such direction shall have been given, by check of the payor payable to the order of, and mailed to, such Indemnitee or Tax Indemnitee or Owner, as the case may be, by certified mail, postage prepaid, at its address as set forth in this Agreement.

8.5. Interest

If any amount, payable by Owner, any Indemnitee or any Tax Indemnitee under Section 8.1 or 8.3 is not paid when due, the person obligated to make such payment shall pay on demand, to the extent permitted by Law, to the person entitled thereto, interest on any such amount for the period from and including the due date for such amount to but excluding the date the same is paid, at the Payment Due Rate. Such interest shall be paid in the same manner as the unpaid amount in respect of which such interest is due.

8.6. Benefit of Indemnities

The obligations of the Owner in respect of all indemnities, obligations, adjustments and payments in Section 8.1 or 8.3 are expressly made for the benefit of, and shall

be enforceable by, the Indemnitee or Tax Indemnitee entitled thereto, notwithstanding any provision of the Security Agreements.

SECTION 9. ASSIGNMENT OR TRANSFER OF INTEREST

9.1. Note Holder

Subject to Section 6.3.2 hereof, and Section 2.07 of the Trust Indenture, the Series B Note Holder may, at any time and from time to time, Transfer or grant participations in all or any portion of the Series B Equipment Note and/or all or any portion of its beneficial interest in the Series B Equipment Note to any person (it being understood that the sale or issuance of Pass Through Certificates by a Pass Through Trustee shall not be considered a Transfer or participation); provided, that any participant in any such participation shall not have any direct rights under the Operative Agreements or any Lien on all or any part of the Collateral and Owner shall not have any increased liability or obligations as a result of any such participation. In the case of any such Transfer, the Transferee, by acceptance of the Series B Equipment Note in connection with such Transfer, shall be deemed to be bound by (i) all of the covenants of the Series B Note Holder contained in the Operative Agreements and (ii) certain terms of the Intercreditor Agreement as specified in the Series B Equipment Note and/or Section 2.07 of the Trust Indenture.

9.2. Effect of Transfer

TO
NOTE PURCHASE AGREEMENT

[Form of Opinion of Owner’s Special Counsel]

February 1, 2021

To the Persons Listed on Schedule I Attached Hereto

Re:

Note Purchase Agreement relating to United Airlines Pass Through Certificates, Series 2020-1B

Ladies and Gentlemen:

We have been requested by United Airlines, Inc., a Delaware corporation (the “Company”), to act as special counsel with respect to, and to render this opinion letter in connection with, the transactions contemplated by the Class B Note Purchase Agreement, dated as of February 1, 2021 (the “Note Purchase Agreement”), among the Company, as Owner, and Wilmington Trust, National Association, a national banking association (“WTNA”), in its capacity as Mortgagee (the “Mortgagee”), as Subordination Agent under the Intercreditor Agreement and as Pass Through Trustee under the Pass Through Trust Agreements. Capitalized terms used herein and not otherwise defined herein have the respective meanings given to those terms pursuant to the Note Purchase Agreement.

In connection with this opinion letter we have examined, among other things, originals or copies certified or otherwise identified to our satisfaction of the following documents:

(i)

the Note Purchase Agreement;

(ii)

the Trust Indenture (after giving effect to the Trust Indenture Amendment);

(iii)

the Trust Indenture Amendment; and

(iv)

the Series B Equipment Note issued under the Trust Indenture at the Class B Closing, in the principal amount set forth on Schedule 2 to the Note Purchase Agreement (the “Series B Equipment Note”).

We have also examined and relied upon such other documents and such other corporate records, certificates and other statements of governmental officials and corporate officers and other representatives of the Company as we have deemed necessary or appropriate for the purposes of this opinion. As to certain facts material to the opinions expressed herein, we have relied upon representations and warranties contained in the Transaction Documents. The opinions expressed herein are subject to the following exceptions, assumptions, qualifications and limitations:

A. The opinions set forth below are limited to the laws of the State of New York, the federal laws of the United States of America and the General Corporation Law of the State of Delaware, except that we express no opinion with respect to (i) the laws, regulations or ordinances of any county, town or municipality or governmental subdivision or agency thereof, (ii) state securities or blue sky laws or federal securities laws, including the Securities Act and the Investment Company Act of 1940, as amended, (iii) any federal or state tax, antitrust or fraudulent transfer or conveyance laws, (iv) the Employee Retirement Income Security Act of 1974, as amended, or (v) the Act (except as expressly provided in paragraph 5 below), the Cape Town Treaty or any other laws, rules or regulations governing, regulating or relating to the acquisition, ownership, registration, use or sale of the Qualified Spare Parts, the Spare Engines or the Aircraft or to the particular nature of the equipment subject to the Lien of the applicable Security Agreement. In addition, our opinions are based upon a review of those laws, statutes, rules and regulations which, in our experience, are normally applicable to transactions of the type contemplated by the Note Purchase Agreement.

B. The opinions set forth in paragraph 3 below are subject to (i) limitations on enforceability arising from applicable bankruptcy, insolvency, reorganization, moratorium, receivership, fraudulent conveyance, fraudulent transfer, preferential transfer and similar laws relating to or affecting the rights and remedies of creditors generally and the effect of general principles of equity, including, without limitation, laches and estoppel as equitable defenses and concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered or applied in a proceeding in equity or at law) and considerations of impracticability or impossibility of performance, and defenses based upon unconscionability of otherwise enforceable obligations in the context of the factual circumstances under which enforcement thereof is sought and (ii) the qualification that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. In addition, certain remedial and procedural provisions of the Transaction Documents are or may be unenforceable in whole or in part, but the inclusion of such provisions does not affect the validity of those agreements and does not, in our opinion, make the remedies provided in those agreements, or otherwise available under applicable law, inadequate for the practical realization of the substantive benefits purported to be provided thereby, except for the economic consequences resulting from any delay imposed by, or any procedure required by, applicable laws, rules,

regulations and by constitutional requirements. We express no opinion as to (i) any provision contained in any Transaction Document (a) providing for indemnification or exculpation of any Person for such Person’s gross negligence, willful misconduct, recklessness or unlawful conduct or in respect of liabilities under the Securities Act, (b) providing for a premium, late payment charges or an increase in interest rate upon delinquency in payment or the occurrence of a default or other specified event but only to the extent such provision is deemed to constitute a penalty or liquidated damages provision, (c) as such provision relates to the subject matter jurisdiction of federal courts or the waiver of inconvenient forum with respect to proceedings in federal courts, (d) that purports to establish (or may be construed to establish) evidentiary standards, (e) providing for the waiver of any statutory right or any broadly or vaguely stated rights or unknown future rights, or any waiver which is against public policy considerations or (f) providing for severability of the provisions of a Transaction Document or (ii) Section 12.8(e) of the Note Purchase Agreement or any comparable provision of any other Transaction Document. Under certain circumstances the requirement that the provisions of a Transaction Document may be modified or waived only in writing or only in a specific instance and provisions to the effect that failure or delay in exercising any right, remedy, power and/or privilege will not impair or waive such right, remedy, power and/or privilege may be unenforceable to the extent that an oral agreement has been effected or a course of dealing has occurred modifying such provisions. A court may modify or limit contractual agreements regarding attorneys’ fees.

C. To the extent that our opinions expressed herein involve conclusions as to the matters set forth in the opinions dated the date hereof of the United Airlines, Inc. Legal Department, ▇▇▇▇▇▇ ▇▇▇▇▇ LLP or ▇▇▇▇▇, ▇▇▇▇▇ & ▇▇▇▇▇, P.C., being delivered to you on the date hereof, we have assumed, without independent investigation, the correctness of the matters set forth in such opinions.

D. We have assumed the due authorization, execution and delivery of the Transaction Documents by each of the parties thereto, that each of such parties (other than the Company) has the power and authority to execute, deliver and perform each such Transaction Document and has obtained or made all necessary consents, approvals, filings and registrations in connection therewith (except any required under New York law by the Company), that such execution, delivery and performance does not violate its charter, by-laws or similar instrument, that value has been given by each Pass Through Trustee to the Company under the Trust Indenture, that the Company had rights in the Collateral on the Closing Date and on the Class B Closing Date and that WTNA is duly organized, validly existing and in good standing in its jurisdiction of organization and qualified to transact business in each other jurisdiction where such qualification is required.

E. We have assumed the due authentication of the Series B Equipment Note by the Mortgagee and the delivery thereof against payment therefor, all in accordance with the Note Purchase Agreement and the Trust Indenture, and that the Series B Equipment Note

conforms to the form thereof examined by us. We have assumed that the Company holds an air carrier operating certificate issued pursuant to Chapter 447 of Title 49 of the United States Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo.

F. We have assumed that all signatures on documents examined by us are genuine, that all persons signing such documents have legal capacity, that all documents submitted to us as originals are authentic and that all documents submitted to us as copies or specimens conform with the originals, which facts we have not independently verified.

G. We have assumed that each Aircraft has been registered in the name of the Company with the FAA pursuant to the Act, that the FAA Filed Documents have been filed with and recorded by the FAA in accordance with the Act, and that the Financing Statements have been filed as contemplated by the Note Purchase Agreement.

H. We express no opinion as to any provision in any Transaction Document that is contrary to Sections 9-401, 9-406, 9-407 or 9-408 or Part VI of Article 9, of the UCC.

I. We have not made any examination of, and express no opinion with respect to (and to the extent relevant have assumed the accuracy and sufficiency of), (i) descriptions of, the legal or beneficial ownership of, or the title or condition of title to, the Collateral or any other property covered by any of the Transaction Documents, (ii) except as expressly set forth in paragraphs 5 and 7 below, the existence, creation, validity or attachment of any Lien thereon, (iii) except as expressly set forth in paragraph 5 below, the perfection of any Lien thereon and (iv) the priority or enforcement of any Lien thereon.

J. In giving an opinion regarding the valid existence and good standing of the Company, we have relied solely upon certificates of public officials.

K. The opinions expressed herein are given as of the date hereof. We assume no obligation to advise you of any facts or circumstance that may come to our attention, or any changes in law that may occur after the date hereof, which may affect the opinion expressed herein.

Based on and subject to the foregoing, we are of the opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware.

2. The Company has all necessary corporate power to execute, deliver and perform its obligations under the Transaction Documents. Neither the execution nor delivery of the Transaction Documents by the Company nor the consummation of the transactions contemplated thereby will result in any violation of (a) its Amended and Restated Certificate of Incorporation or Amended and Restated By-laws or (b) any law, governmental rule or regulation

known to us to be applicable to, or binding on, the Company, or requires the approval of the stockholders of the Company.

3. Each Transaction Document constitutes the valid and binding obligation of the Company and is enforceable against the Company in accordance with its terms.

4. Except for the matters referred to in clauses (i) and (ii) of paragraph 5 below and the filing for recordation (and recordation) in accordance with the Act of the Trust Indenture Amendment, no approval, authorization or other action by or filing with any governmental authority is required for the execution and delivery by the Company of the Transaction Documents or the consummation of the transactions contemplated thereby to occur at the Class B Closing.

5. Except for (i) the periodic renewal of the registration of each Aircraft with the FAA pursuant to the Act in the name of the Company prior to its expiration, and (ii) the filing of continuation statements to continue the effectiveness of the Financing Statements, (a) no further filing or recording of any document is necessary (x) to establish the Company’s title to the Aircraft, the Spare Engines or the Pledged Spare Parts, and (y) to create a valid security interest in the Company’s interest as owner of the Aircraft, the Spare Engines or the Pledged Spare Parts (to the extent a security interest therein is created by the applicable Security Agreement) in favor of the Mortgagee pursuant to the applicable Security Agreement and (b) no further filing or recording of any document in the State of New York or under the Act is required to perfect a security interest in the Company’s interest as owner of the Aircraft, the Spare Engines or the Pledged Spare Parts (to the extent a security interest therein is created by the applicable Security Agreement) in favor of the Mortgagee pursuant to the applicable Security Agreement.

6. The Mortgagee will be entitled to the benefits of Section 1110 of Title 11 of the United States Code with respect to the Aircraft, the Spare Engines and the Pledged Spare Parts in connection with any case commenced by or against the Company under Chapter 11 of Title 11 of the United States Code.

7. Upon issuance, execution, authentication and delivery of the Series B Equipment Note at the Class B Closing, each of the Trust Indenture, the Spare Engines Security Agreement and the Spare Parts Security Agreement will have created the security interest in favor of the Mortgagee, as trustee for the benefit of, among others, the holder of the Series B Equipment Note, in the Aircraft, the Spare Engines and the Pledged Spare Parts, respectively, it purports to create to the extent that the UCC applies to a security interest in such property.

This opinion is being delivered pursuant to Section 4.1.2(vi)(A) of the Note Purchase Agreement. This opinion may be relied upon by you (and any permitted Transferee under Section 9.1 of the Note Purchase Agreement) in connection with the matters set forth

herein and, without our prior written consent, may not be relied upon for any other purpose and may not be relied upon by any other Person for any purpose.

Very truly yours,

[Form of Opinion of Owner’s Legal Department]

February 1, 2021

To the Persons Listed on Schedule I Attached Hereto

Re:

Note Purchase Agreement relating to United Airlines Pass Through Certificates, Series 2020-1B

Ladies and Gentlemen:

This opinion letter is being delivered by United Airlines, Inc., a Delaware corporation (“United”), through its Legal Department in connection with the transactions contemplated by the Class B Note Purchase Agreement, dated as of February 1, 2021, among Wilmington Trust, National Association, a national banking association, as Mortgagee, as Subordination Agent under the Intercreditor Agreement and as Pass Through Trustee under the Pass Through Trust Agreements, and United, as Owner (the “Note Purchase Agreement”). All capitalized terms used herein and not otherwise defined herein shall have the respective meanings given those terms pursuant to the Note Purchase Agreement. This opinion letter is being furnished to you pursuant to Section 4.1.2(vi)(B) of the Note Purchase Agreement.

In giving the following opinions, members of United’s Legal Department or lawyers retained by United’s Legal Department have reviewed the Trust Indenture, the Note Purchase Agreement and the other Transaction Documents to which United is a party and have relied upon originals, or copies certified or otherwise identified to our satisfaction, of such records, documents, certificates and other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. In addition, United’s Legal Department has assumed and has not verified the accuracy as to factual matters of each document reviewed. As used herein, the phrase “to our knowledge” or words of similar import shall mean to the actual knowledge of members of United’s Legal Department after reasonable investigation, but shall not be interpreted to impute to any member of United’s Legal Department knowledge of others.

Based on the foregoing, and subject to the assumptions and limitations contained herein, United’s Legal Department is of the opinion that:

(a) United is an “air carrier” within the meaning of Section 40102 of the Act, holds an air carrier operating certificate issued pursuant to Chapter 447 of Title 49 of the United States Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of cargo, is a “citizen of the United States” as such term is defined in Section 40102 of such Act and holds all authority, necessary licenses and certificates under such Act and the rules and regulations promulgated thereunder necessary for the conduct of its business and to perform its obligations under the Transaction Documents.

(b) The execution, delivery and performance by United of each of the Transaction Documents do not, to our knowledge, constitute a breach or result in a default under any indenture, mortgage, deed of trust, credit agreement, conditional sale contract or other loan agreement to which United is a party or by which United or its property may be bound.

(c) The execution, delivery and performance of each of the Transaction Documents has been duly authorized by all necessary corporate action on the part of United, and each of the Transaction Documents has been duly executed and delivered by United.

(d) There are no pending or, to our knowledge, threatened actions, suits or proceedings before any court or administrative agency or arbitrator that question the validity of any of the Transaction Documents or that would have been required to be disclosed in United’s Annual Report on Form 10-K filed for the year ended December 31, 2019, or any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K (or amendment to any of the foregoing), except such as are therein disclosed.

The foregoing opinions are limited to the federal law of the United States of America (other than (i) the Act (except as expressly provided in paragraph (a) above), the Cape Town Treaty or any other laws, rules or regulations governing, regulating or relating to the acquisition, ownership, registration, use or sale of the Qualified Spare Parts, the Spare Engines or the Aircraft or to the particular nature of the equipment to be subject to the Lien of the applicable Security Agreement, (ii) federal securities laws, (iii) federal tax, antitrust or fraudulent transfer or conveyance laws, as to which we express no opinion), the General Corporation Law of the State of Delaware and the law of the State of Illinois (other than state securities or blue sky laws, or state tax, antitrust or fraudulent transfer or conveyance laws, as to which we express no opinion).

This opinion letter can be relied upon only by you for the purpose indicated above, and may not be relied upon by any other Person (except any permitted Transferee under Section 9.1 of the Note Purchase Agreement) or for any other purpose without our written consent.

Very truly yours,

United Airlines, Inc.

OPINION OF SPECIAL COUNSEL TO MORTGAGEE AND TO THE PASS THROUGH TRUSTEES

February 1, 2021

To Each of the Parties Listed on Schedule A Hereto

Re:

United Airlines, Inc.

Ladies and Gentlemen:

We have acted as counsel to Wilmington Trust, National Association (“WTNA”), in connection with the Class B Note Purchase Agreement , dated as of February 1, 2021 (the “Note Purchase Agreement”), among United Airlines, Inc., as Owner and WTNA, as Mortgagee, Subordination Agent under the Intercreditor Agreement and as Pass Through Trustee under the Pass Through Trust Agreements. This opinion is furnished pursuant to Section 4.1.2 (vi)(C) of the Note Purchase Agreement. Capitalized terms used herein and not otherwise defined are used as defined in the Note Purchase Agreement, except that reference herein to any document shall mean such document as in effect on the date hereof.

We have examined originals or copies of the following documents:

(a)

The Trust Indenture (after giving effect to the Trust Indenture Amendment;

(b)

The Trust Indenture Amendment;

(c)

The Note Purchase Agreement (the documents referred to in paragraphs (a) through (c) being collectively referred to as the “Transaction Documents”); and

(d)

The Series B Equipment Note issued under the Trust Indenture at the Class B Closing, in the principal amount set forth on Schedule 2 to the Note Purchase Agreement (the “Series B Equipment Note”).

We have also examined originals or copies of such other documents and such corporate records, certificates and other statements of governmental officials and corporate officers and other representatives of the corporations or entities referred to herein as we have deemed necessary or appropriate for the purposes of this opinion.

Based upon the foregoing and upon an examination of such questions of law as we have considered necessary or appropriate, and subject to the assumptions, exceptions and

To Each of the Parties Listed on Schedule A Hereto
February 1, 2021
Page 2

qualifications set forth below, we advise you that, in our opinion:

1. WTNA has been duly incorporated and is validly existing in good standing as a national banking association under the laws of the United States of America, is a “citizen of the United States” within the meaning of Section 40102(a)(15) of Title 49 of the United States Code, as amended, and has full power, authority and legal right to execute, deliver and perform its obligations under the Transaction Documents and to authenticate the Series B Equipment Note.

2. The Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be, have duly authorized, executed and delivered each Transaction Document to which it is party, and the Series B Equipment Note, and each such document constitutes a legal, valid and binding obligation of the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be, enforceable against the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be, in accordance with its terms.

3. The execution, delivery and performance by the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be, of the Transaction Documents to which it is a party, the authentication by the Mortgagee of the Series B Equipment Note and the consummation by the Mortgagee, the Subordination Agent, the Pass Through Trustee or WTNA, as the case may be, of any of the transactions contemplated thereby are not in violation of the charter or by-laws of WTNA or of any law, governmental rule or regulation of the State of Delaware or the United States governing the trust powers of WTNA or, to our knowledge, any indenture, mortgage, bank credit agreement, note or bond purchase agreement, long-term lease, license or other agreement or instrument to which WTNA is a party or by which it is bound or, to our knowledge, any judgment or order applicable to WTNA.

4. None of the execution and delivery by the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be, of the Transaction Documents to which it is a party, the authentication of the Series B Equipment Note or the consummation of any of the transactions by the Mortgagee, the Subordination Agent, the Pass Through Trustee or WTNA, as the case may be, contemplated thereby, requires the consent or approval of, the giving of notice to, the registration with, or the taking of any other action in respect of, any governmental authority or agency of the State of Delaware or the United States governing the trust powers of WTNA or under any Delaware law.

5. No taxes, fees or other charges (other than taxes payable by WTNA on or measured by any compensation received by WTNA for its services as Mortgagee, Subordination Agent or Pass Through Trustee) are required to be paid by the Subordination Agent, the Pass Through Trustees or the Mortgagee or the trust created by the Trust Indenture under the laws of the State of Delaware, or any political subdivision thereof, in connection with the execution, delivery or performance of the Transaction Documents to which the Mortgagee, the Subordination Agent or the Pass Through Trustees is party and the Series B Equipment Note, which taxes, fees or other charges would not be required to be paid if WTNA were not a national

banking association and did not perform its obligations as Mortgagee under the Trust Indenture in the State of Delaware.

6. The Series B Equipment Note has been duly and validly authenticated by the Mortgagee in accordance with the Trust Indenture.

7. To our knowledge, there are no proceedings pending or threatened against or affecting the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA in any court or before any governmental authority, agency, arbitration board or tribunal which, if adversely determined, individually or in the aggregate, would materially and adversely affect the Mortgaged Property or the right, power and authority of the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be, to enter into or perform its obligations under the Transaction Documents to which it is party.

The foregoing opinions are subject to the following assumptions, exceptions and qualifications:

A. We are admitted to practice law in the State of Delaware and we do not hold ourselves out as being experts on the law of any other jurisdiction. The foregoing opinions are limited to the laws of the State of Delaware (and its political subdivisions to the extent set forth in paragraph 5 above), the federal laws of the United States of America governing the banking and trust powers of WTNA, except that we express no opinion with respect to (i) federal securities laws, including the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the Investment Company Act of 1940, as amended, and the Trust Indenture Act of 1939, as amended, (ii) Part A of Subtitle VII of Title 49 of the United States Code, as amended (except with respect to the opinion set forth in paragraph 1 above concerning the citizenship of WTNA), (iii) the Federal Communications Act of 1934, as amended, (iv) state securities or blue sky laws, or (v) laws, rules and regulations applicable to the particular nature of the equipment acquired by the Company. Insofar as the foregoing opinions relate to the validity and enforceability of the Transaction Documents expressed to be governed by the laws of the State of New York, we have assumed that each such document is legal, valid, binding and enforceable in accordance with its terms under such laws (as to which we express no opinion).

B. The foregoing opinions regarding enforceability are subject to (i) applicable bankruptcy, insolvency, moratorium, reorganization, receivership, fraudulent conveyance and similar laws relating to or affecting the enforcement of the rights and remedies of creditors generally, and (ii) principles of equity (regardless of whether considered and applied in a proceeding in equity or at law).

C. We have assumed that each of the parties to the Transaction Documents and the Series B Equipment Note (except the Mortgagee, the Subordination Agent, the Pass Through Trustees or WTNA, as the case may be) has full power, authority and legal right to execute, deliver and perform each such document and that each such document has been duly authorized, executed and delivered by each such party.

To Each of the Parties Listed on Schedule A Hereto

D. We have assumed that all signatures (other than signatures of officers of WTNA) on documents examined by us are genuine, that all documents submitted to us as originals are authentic and that all documents submitted to us as copies conform with the originals, which facts we have not independently verified.

E. We have assumed that the Note Purchase Agreement and the transactions contemplated thereby are not within the prohibitions of Section 406 of the Employee Retirement Income Security Act of 1974, as amended.

F. No opinion is expressed as to the creation, attachment, perfection or priority of any mortgage or security interests or as to the nature or validity of title to any part of the Mortgaged Property.

G. The opinion set forth in paragraph (1) above concerning the citizenship of WTNA is based upon an affidavit of WTNA, made by one of its Vice Presidents, the facts set forth in which we have not independently verified.

H. In basing the opinions set forth herein on “our knowledge,” the words “our knowledge” signify that no information has come to the attention of the attorneys in the firm who are directly involved in the representation of WTNA in this transaction that would give us actual knowledge that any such opinions are not accurate. Except as otherwise stated herein, we have undertaken no independent investigation or verification of such matters.

This opinion may be relied upon by you in connection with the matters set forth herein. This opinion may also be relied upon by any transferee of a Note Holder subject to the understanding that the opinions expressed herein are rendered as of the date hereof and only with respect to the laws, rules and regulations in effect as of such date. Otherwise, without our prior written consent, this opinion may not be relied upon by any other person or entity for any purpose.

Very truly yours,

Re:

The aircraft with manufacturer’s serial numbers and United States nationality
and registration marks listed on the attached Appendix A (the “Aircraft”)

To the Addressees Listed on the Attached Exhibit A

Ladies and Gentlemen:

Acting as special legal counsel in connection with the transactions contemplated by the instruments described below, this opinion is furnished to you with respect to: (i) registering interests with the International Registry (the “International Registry”) created pursuant to and in accordance with the provisions of the Convention on International Interests in Mobile Equipment, the Protocol to the Convention on International Interests in Mobile Equipment on Matters Specific to Aircraft Equipment, both signed in Cape Town, South Africa on November 16, 2001, together with the Regulations for the International Registry, the International Registry Procedures, and all other rules, amendments, supplements, revisions thereto (collectively the “Cape Town Treaty”), all as in effect on this date in the United States of America, as a Contracting State, as defined in the Cape Town Treaty (a “Contracting State”), and the requirements of Title 49 of the United States Code (the “Transportation Code”); and (ii) pertaining to the recordation of instruments and the registration of aircraft pursuant to the Transportation Code and the continued validity of interests under the Cape Town Treaty and the Transportation Code.

This letter confirms that we filed with the Federal Aviation Administration (the “FAA”) today at __:__ _.M., C.S.T., Amendment No. 1 to Trust Indenture and Mortgage dated as of this date (the “Mortgage Amendment”) between United Airlines, Inc. as Owner (the “Owner”) and Wilmington Trust, National Association, as Mortgagee (the “Mortgagee”) amending the Trust Indenture and Mortgage dated as of October 28, 2020, by the Owner in favor of the Mortgagee, as supplemented by Mortgage Supplement No. 1 dated October 28,

Page 2

2020, recorded by the FAA on December 14, 2020, as Conveyance No. LC016144 and Trust Indenture and Mortgage Supplement No. 2 dated January 21, 2021, filed with the FAA on January 21, 2021, and not yet recorded (the “Mortgage”) covering the Aircraft and the aircraft engines with manufacturer’s serial numbers listed on the attached Appendix A (the “Engines”).

Based upon our examination of said instrument and of such records of the FAA and the Priority Search Certificates (the “Priority Search Certificates”) issued by the International Registry as we deemed necessary to render this opinion and as were made available to us by the FAA and the International Registry, it is our opinion that:

(a)

based on the type certificate data sheets issued by the FAA, the Aircraft and the Engines constitute “aircraft objects” as defined by the Cape Town Treaty;

(b)

the Mortgage Amendment is in due form for recording and has been duly filed for recordation with the FAA pursuant to and in accordance with the provisions of the Transportation Code;

(c)

the Owner is owner of legal title to the Aircraft, with a Certificate of Aircraft Registration duly issued to the Owner pursuant to and in accordance with the provisions of the Transportation Code;

(d)

the Aircraft and the Engines are free and clear of all Liens (as such term is defined in the Mortgage) of record with the FAA except the security interest created by the Mortgage, as amended by the Mortgage Amendment;

(e)

based on the Priority Search Certificates issued by the International Registry, the Aircraft and the Engines are subject to the International Interests by the Owner as debtor to the Mortgagee as creditor (the “Mortgage International Interest”) and assigned the International Registry File Nos. as listed on the attached Appendix;

(f)

the Mortgage International Interest is a duly registered first priority International Interest as defined in the Cape Town Treaty in favor of the Mortgagee in the Aircraft and the Engines, subject to the terms of the Cape Town Treaty;

_(g)

the Mortgage, as amended by the Mortgage Amendment, constitutes a valid, duly perfected mortgage and security interest in favor of the Mortgagee in the Aircraft and the Engines pursuant to and in accordance with the Transportation Code, subject to the terms of the Cape Town Treaty;

Page 3

(h)

no further registration with the International Registry of the Mortgage International Interest is required under the Cape Town Treaty and no filings or recordings of the Mortgage or the Mortgage Amendment (other than the filings and recordings with the FAA which have been effected) are necessary to perfect and maintain the effectiveness and priority of the interests created thereunder; and

(i)

no authorization, approval, consent, license or order of, or registration with, or giving of notice to, the FAA Aircraft Registry or the International Registry is required for the valid authorization, delivery or performance of the Mortgage or the Mortgage Supplement, or to maintain the effectiveness and priority thereof, except for such authorizations, approvals, consents, licenses, orders, registrations and notices as have been effected.

No opinion is herein expressed as to: (i) laws other than the federal laws of the United States; (ii) the validity or enforceability under local law of the Mortgage, as amended by the Mortgage Amendment; and (iii) the recognition of the perfection of the security interest created by the Mortgage, as amended by the Mortgage Amendment, as against third parties in any legal proceedings outside the United States. Since our examination was limited to records maintained by the FAA Aircraft Registry and the International Registry, our opinion does not cover liens which are perfected without the filing of notice thereof with the FAA and without the registration of notice thereof with the International Registry, such as federal tax liens, liens arising under Section 1368(a) of Title 29 of the United States Code and possessory artisans’ liens, and is subject to: (i) the accuracy of FAA personnel in the filing, indexing, posting, recording and additions to the Registry Modernization System of instruments filed with the FAA and in the search for encumbrance cross-reference index records for the Engines; (ii) the accuracy of the information contained in the Priority Search Certificates; and (iii) the inclusion of all registered interests associated with the Aircraft and the Engines in the Priority Search Certificates. We have assumed that the instruments in the records maintained by the FAA for the Aircraft and the Engines and the instruments supporting the registrations on the International Registry are sufficient under the relevant local law to create or terminate the interests they purport to create or terminate.

Very truly yours,
