Item 1.01 Entry into a Material Definitive Agreement.

On November 17, 2015, United Airlines, Inc. (the “Company”) and Wilmington Trust, National Association, as subordination agent and pass through trustee (the “Trustee”) under certain pass through trusts newly formed by the Company, entered into the Note Purchase Agreement, dated as of November 17, 2015 (the “Note Purchase Agreement”). The Note Purchase Agreement provides for the issuance by the Company of equipment notes (the “Equipment Notes”) in the aggregate principal amount of $433,652,000 to finance 10 new Boeing aircraft delivered to United between August 2015 and December 2015 (collectively, the “Aircraft”).

Pursuant to the Note Purchase Agreement, on November 17, 2015, the Trustee purchased Equipment Notes issued under a trust indenture and mortgage (each, an “Indenture” and, collectively, the “Indentures”) with respect to each Aircraft entered into by the Company and Wilmington Trust, National Association, as mortgagee. Each Indenture provides for the issuance of Equipment Notes in two series: Series AA, bearing interest at the rate of 3.45% per annum, and Series A, bearing interest at the rate of 3.70% per annum, in aggregate principal amounts equal to $333,652,000 and $100,000,000, respectively. The Equipment Notes were purchased by the Trustee, using the proceeds from the sale of Pass Through Certificates, Series 2015-1AA, and Pass Through Certificates, Series 2015-1A (collectively, the “Certificates” and each series of the Certificates, a “Class”) issued by two pass through trusts newly-formed by the Company to facilitate the financing of the Aircraft.

As of November 17, 2015, nine of the Aircraft had been delivered to the Company and were pledged as collateral for the Equipment Notes. The remaining Boeing 787-9 Aircraft to be financed pursuant to the Note Purchase Agreement is scheduled for delivery to the Company in November 2015. The Equipment Notes relating to such remaining Aircraft have been secured initially by the cash used to purchase such Equipment Notes and by a letter of credit in an amount sufficient to repay such Equipment Notes as described below. If such remaining Aircraft is delivered by The Boeing Company to the Company on or before December 17, 2015, the Company will pledge it as collateral for the related Equipment Notes and the cash and letter of credit initially securing such Equipment Notes will be released to the Company. If such Aircraft is not pledged as collateral by December 17, 2015, on the next business day the Company will prepay the related Equipment Notes at their principal amount, without make-whole premium, plus accrued interest.

The interest on the Equipment Notes is payable semi-annually on each June 1 and December 1, beginning on June 1, 2016. The principal payments on the Series AA Equipment Notes are scheduled on June 1 and December 1 of each year, beginning on December 1, 2016, with final payments scheduled for December 1, 2027. The entire principal amount of the Series A Equipment Notes is scheduled for payment on December 1, 2022. 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 applicable Indenture when due or to comply with certain covenants, as well as certain bankruptcy events involving the Company. Except as, and to the extent, otherwise provided herein, the Equipment Notes issued with respect to each Aircraft will be secured by a lien on such Aircraft and will also be cross-collateralized by the other Aircraft financed pursuant to the Note Purchase Agreement.

The 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. 333-203630) (the “Registration Statement”). 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 and are incorporated by reference herein. For a more detailed description of the agreements and instruments entered into by the Company with respect to the Certificates, see the disclosure under the captions “Description of the Certificates”, “Description of the Liquidity Facilities”, “Description of the Intercreditor Agreement”, “Description of the Equipment Notes” and “Underwriting” contained in the Company’s final Prospectus Supplement, dated November 2, 2015 (the “Prospectus Supplement”), to the Prospectus, dated April 24, 2015, filed with the Securities and Exchange Commission on November 3, 2015 pursuant to Rule 424(b) under the Securities Act, which disclosure is hereby incorporated herein by reference.

Ladies and Gentlemen:

United Airlines, Inc., a Delaware corporation (the “Company”), proposes that Wilmington Trust, National Association, as trustee under each of the Trusts (as defined below) (each, a “Trustee”), issue and sell to the underwriters named in Schedule II hereto United Airlines Pass Through Certificates, Series 2015-1AA (the “Class AA Certificates”) and United Airlines Pass Through Certificates, Series 2015-1A (the “Class A Certificates” and, together with the Class AA Certificates, the “Certificates”), in the aggregate face amounts and with the interest rates and final expected distribution dates set forth on Schedule I hereto on the terms and conditions stated herein.

The Certificates will be issued pursuant to a Pass Through Trust Agreement, dated as of October 3, 2012 (the “Basic Agreement”), between the Company and the Trustee, as supplemented with respect to the issuance of each class of Certificates by a separate Pass Through Trust Supplement to be dated as of the Closing Date (as defined below) (individually, a “Trust Supplement”), between the Company and the Trustee (the Basic Agreement as supplemented by each such Trust Supplement being referred to herein individually as a “Pass

Through Trust Agreement”). The Trust Supplements are related to the creation and administration of United Airlines Pass Through Trust 2015-1AA (the “Class AA Trust”) and United Airlines Pass Through Trust 2015-1A (the “Class A Trust” and, together with the Class AA 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 “Representatives” shall mean, collectively, Morgan Stanley & Co. LLC (“Morgan Stanley”) and Credit Suisse Securities (USA) LLC, on behalf of the Underwriters.

Certain amounts of interest payable on the Certificates issued by the Class AA Trust and the Class A Trust will be entitled, in each case, to the benefits of a separate liquidity facility. Commonwealth Bank of Australia, New York Branch (the “Class AA Liquidity Provider”) and Crédit Agricole Corporate and Investment Bank, acting through its New York Branch (the “Class A Liquidity Provider” and, together with the Class AA Liquidity Provider, the “Liquidity Providers”), will enter into separate revolving credit agreements with respect to the Class AA Trust and the Class A Trust (collectively, the “Liquidity Facilities”) to be dated as of the Closing Date for the benefit of the holders of the Certificates issued by such Trusts. The Liquidity Providers and the holders of the Certificates will be entitled to the benefits of an Intercreditor Agreement to be dated as of the Closing Date (the “Intercreditor Agreement”) among the Trustees, Wilmington Trust, National Association, as subordination agent and trustee thereunder (the “Subordination Agent”), and the Liquidity Providers.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (File No. 333-203630) relating to securities, including pass through certificates (the “Shelf Securities”), to be issued from time to time by the Company. The registration statement (including the respective exhibits thereto and the respective documents filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”), that are incorporated by reference therein), as amended to and including the date of this Underwriting Agreement (the “Agreement”), including the information (if any) deemed to be part of the registration statement pursuant to Rule 430B under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”) (and the Underwriters confirm that the first contract of sale of the Certificates by the Underwriters was made on the date of this Agreement), is hereinafter referred to as the “Registration Statement”, and the related prospectus covering the Shelf Securities dated April 24, 2015 filed as part of the Registration Statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement, is hereinafter referred to as the “Basic Prospectus”. The Basic Prospectus, as supplemented by the final prospectus supplement specifically relating to the Certificates in the form as first filed with the Commission pursuant to Rule 424(b) under the Securities Act in accordance with Section 4(d) hereof is hereinafter referred to as the “Prospectus”, and the term “preliminary prospectus” means any preliminary form of the Prospectus filed with the Commission pursuant to Rule 424 under the Securities Act. For purposes of this Agreement, (i) “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and (ii) “Time of Sale Prospectus” means the preliminary prospectus together with the free writing prospectus identified in Item 1 of Schedule IV hereto. As used herein, the terms “Registration Statement”, “Basic Prospectus”, “preliminary prospectus”, “Time of Sale Prospectus” and

“Prospectus” shall include the documents, if any, incorporated by reference therein. The terms “supplement”, “amendment” and “amend” as used herein with respect to the Registration Statement, the Basic Prospectus, the Time of Sale Prospectus, the Prospectus, any preliminary prospectus or any free writing prospectus shall include all documents subsequently filed by the Company with the Commission pursuant to the Exchange Act and incorporated by reference therein.

Capitalized terms used but not defined in this Underwriting Agreement (the “Agreement”) shall have the meanings specified therefor in the Pass Through Trust Agreements, the Note Purchase Agreement to be dated as of the Closing Date (the “Note Purchase Agreement”) among the Company, Wilmington Trust, National Association, as Trustee of each of the Trusts, or the Intercreditor Agreement; provided that, as used in this Agreement, the term “Operative Agreements” shall mean the Intercreditor Agreement, the Liquidity Facilities, the Pass Through Trust Agreements and the Financing Agreements (as defined in the Note Purchase Agreement).

1. Representations and Warranties. (a) The Company represents and warrants to, and agrees with each Underwriter that:

(i) The Company meets the requirements for use of Form S-3 under the Securities Act; the Registration Statement has become effective; and, on the original effective date of the Registration Statement, the Registration Statement complied in all material respects with the requirements of the Securities Act; no stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Company, threatened by the Commission. The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act) and the Company is a “well-known seasoned issuer” (as defined in Rule 405 under the Securities Act) eligible to use the Registration Statement as an automatic shelf registration statement, and the Company has not received notice that the Commission objects to the use of the Registration Statement as an automatic shelf registration statement. The Registration Statement does not, as of the date hereof, include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. As of its date and on the Closing Date, the Prospectus, as amended and supplemented, if the Company shall have made any amendment or supplement thereto, does not and will not include an untrue statement of a material fact and does not and will not omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Registration Statement, as of the date hereof, complies and the Prospectus complies, and as amended or supplemented, if applicable, will comply in all material respects with the Securities Act and the applicable rules and regulations of the Commission thereunder. The Time of Sale Prospectus did not, as of 3:55 p.m., Eastern Time, on the date of this Agreement (the “Applicable Time”), and the Time of Sale Prospectus, as then amended or supplemented by the Company, if applicable, will not as of the Closing Date, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not

misleading. Any information included in any “issuer free writing prospectus” (as defined in Rule 433(h) under the Securities Act) used in connection with the offering of the Certificates does not conflict with the information contained in the Registration Statement, including any prospectus or prospectus supplement that is part of the Registration Statement (including pursuant to Rule 430B under the Securities Act) and not superseded or modified and, when taken together with the Time of Sale Prospectus, as amended and supplemented, each such “issuer free writing prospectus”, as amended and supplemented, did not as of the Applicable Time, and will not as of the Closing Date, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentences do not apply to statements in or omissions from the Registration Statement, the Time of Sale Prospectus or the Prospectus based upon (A) written information furnished to the Company by any Underwriter through the Representatives expressly for use therein or (B) statements or omissions in that part of each Registration Statement which shall constitute the Statement of Eligibility of the Trustee under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), on Form T-1.

(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.

(iii) The Company is not an “ineligible issuer” in connection with the offering of the Certificates pursuant to Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Each free writing prospectus that the Company has filed in connection with the offering of the Certificates, or is required to file in connection with the offering of the Certificates, pursuant to Rule 433(d) under the Securities Act complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Except for the free writing prospectuses, if any, identified in Schedule IV hereto, the Company has not prepared, used or referred to, any free writing prospectus in connection with the offering of the Certificates.

(iv) The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own, lease and operate its property and to conduct its business as described in the Time of Sale Prospectus; and the Company 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 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) Each of Continental Micronesia, Inc. and Air Micronesia, Inc. (together, the “Subsidiaries”) has been duly incorporated and is an existing corporation in good standing under the laws of the jurisdiction of its incorporation, with corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Prospectus; and each 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 issued and outstanding capital stock of each Subsidiary has been duly authorized and validly issued and is fully paid and nonassessable; and, except as described in the Time of Sale Prospectus, each Subsidiary’s capital stock owned by the Company, directly or through subsidiaries, is owned free from liens, encumbrances and defects.

(vi) Except as described in the Time of Sale Prospectus, the Company is not in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other instrument to which it is a party or by which it may be bound or to which any of its properties may be subject, except for such defaults that would not have a United Material Adverse Effect. 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 Regulatory Authority, Inc. (“FINRA”), and (y) filings or recordings with the Federal Aviation Administration (the “FAA”) and under the Uniform Commercial Code (the “UCC”) or other laws in effect in any applicable jurisdiction governing the perfection of security interests, which filings or recordings referred to in this clause (y), with respect to

any particular set of Financing Agreements, shall have been made, or duly presented for filing or recordation, or shall be in the process of being duly filed or filed for recordation, on or prior to the date required therefor under the applicable Financing Agreements for each of the six Boeing 737-924ER aircraft and four Boeing 787-9 aircraft (collectively, the “Aircraft”) related to such Financing Agreements.

(viii) This Agreement has been duly authorized, executed and delivered by the Company and the Operative Agreements to which the Company will be a party have been duly authorized and will be duly executed and delivered by the Company on or prior to the Closing Date.

(ix) 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 Indentures may also be limited by applicable laws which may affect the remedies provided therein but which do not affect the validity of the Indentures 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. The Certificates and the Pass Through Trust Agreements will, upon execution and delivery thereof, conform in all material respects to the descriptions thereof in the Time of Sale Prospectus.

(x) The consolidated financial statements of the Company incorporated by reference in the Time of Sale Prospectus, together with the related notes thereto, present fairly in all material respects the financial position of the Company and its consolidated subsidiaries at the dates indicated and the consolidated results of operations and cash flows of the Company and its consolidated subsidiaries for the periods specified. Such financial statements have been prepared in conformity with generally accepted accounting principles applied on a consistent basis throughout the periods involved, except as otherwise stated therein and except that unaudited financial statements do not have all required footnotes. The financial statement schedules, if any, incorporated by reference in the Time of Sale Prospectus present the information required to be stated therein.

(xi) The Company 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 holds an air carrier operating certificate issued pursuant to Chapter 447 of Title 49 of the United States Code, as amended, for aircraft capable of carrying 10 or more individuals or 6,000

pounds or more of cargo. All of the outstanding shares of capital stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable.

(xii) On or prior to the Closing Date, the issuance of the Certificates will be duly authorized by the Trustee. When duly executed, authenticated, issued and delivered in the manner provided for in the Pass Through Trust Agreements and sold and paid for as provided in this Agreement, the Certificates will be legally and validly issued and will be entitled to the benefits of the relevant Pass Through Trust Agreement.

(xiii) Except as disclosed in the Time of Sale Prospectus, the Company and the Subsidiaries have good and marketable title to all real properties and all other properties and assets owned by them, in each case free from liens, encumbrances and defects except where the failure to have such title would not have a United Material Adverse Effect; and except as disclosed in the Time of Sale Prospectus, the Company and the Subsidiaries hold any leased real or personal property under valid and enforceable leases with no exceptions that would have a United Material Adverse Effect.

(xiv) Except as disclosed in the Time of Sale Prospectus, there is no action, suit or proceeding before or by any governmental agency or body or court, domestic or foreign, now pending or, to the knowledge of the Company, threatened against the Company or any of its subsidiaries or any of their respective properties that individually (or in the aggregate in the case of any class of related lawsuits), could reasonably be expected to result in a United Material Adverse Effect or that could reasonably be expected to materially and adversely affect the consummation of the transactions contemplated by this Agreement or the Operative Agreements.

(xv) Except as disclosed in the Time of Sale Prospectus, no labor dispute with the employees of the Company or any subsidiary exists or, to the knowledge of the Company, is imminent that could reasonably be expected to have a United Material Adverse Effect.

(xvi) Each of the Company and the Subsidiaries has all necessary consents, authorizations, approvals, orders, certificates and permits of and from, and has made all declarations and filings with, all federal, state, local and other governmental authorities, all self-regulatory organizations and all courts and other tribunals, to own, lease, license and use its properties and assets and to conduct its business in the manner described in the Prospectus, except to the extent that the failure to so obtain, declare or file would not have a United Material Adverse Effect.

(xvii) Except as disclosed in the Time of Sale Prospectus, (x) neither the Company nor any of the Subsidiaries is in violation of any statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or foreign, relating to the use, disposal or release of hazardous or toxic substances (collectively, “environmental laws”), owns or operates any real property contaminated with any substance that is subject to any environmental laws, or is subject to any claim relating to any environmental laws, which violation, contamination, liability or claim individually or

in the aggregate is reasonably expected to have a United Material Adverse Effect, and (y) the Company is not aware of any pending investigation which might lead to such a claim that is reasonably expected to have a United Material Adverse Effect.

(xviii) Ernst & Young LLP, who examined and issued an auditors’ report with respect to the consolidated financial statements of the Company and the financial statement schedules of the Company, if any, included or incorporated by reference in the Registration Statement, is an independent registered public accounting firm with respect to the Company and its subsidiaries within the meaning of the Securities Act.

(xix) Each preliminary prospectus filed pursuant to Rule 424 under the Securities Act and included in the Time of Sale Prospectus, complied when so filed in all material respects with the Securities Act and the applicable rules and regulations of the Commission thereunder.

(xxviii) None of the Company nor any of its subsidiaries (collectively, the “Company Entity”) or, to the knowledge of the Company, any director, executive officer or affiliate of the Company Entity is an individual or entity (“Person”) that is controlled by a Person that is currently the subject of any sanctions administered or enforced by the U.S. Department of Treasury’s Office of Foreign Assets Control (“OFAC”) (collectively, “Sanctions”); and the Company represents and covenants that the Company will not, directly or indirectly, use the proceeds of the offering of the Certificates, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other Person (x) to fund or facilitate any activities or business of or with any Person or in any country or territory that, at the time of such funding or facilitation, is the subject of Sanctions, or (y) in any other manner that will result in a violation of Sanctions by any Person (including any Person participating in this offering, whether as underwriter, advisor, investor or otherwise).

(b) The parties agree that any certificate signed by a duly authorized officer of the Company and delivered to an Underwriter, or to counsel for the Underwriters, on the Closing Date and in connection with this Agreement or the offering of the Certificates, shall be deemed a representation and warranty by (and only by) the Company to the Underwriters as to the matters covered thereby.

The Company will furnish the Underwriters with such conformed copies of such opinions, certificates, letters and documents as the Underwriters may reasonably request.

4. Certain Covenants of the Company. The Company covenants with each Underwriter as follows:

(a) During the period described in the following sentence of this Section 4(a), the Company shall advise the Representatives 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 Representatives, which consent will not be unreasonably withheld. If, at any time after the public offering of the 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 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 Representatives will furnish to the Company) to which Certificates may have been sold by the Representatives 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 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 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 Certificates that each severally has agreed to purchase, the name of each Underwriter, if any, acting as representative of the Underwriters in connection with the offering, the price at which the Certificates are to be purchased by the Underwriters from the Trustee, any initial public offering price, any selling concession and reallowance and any delayed delivery arrangements, and such other information as the Representatives and the Company deem appropriate in connection with the offering of the 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 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 Representatives reasonably object.

(f) If the Time of Sale Prospectus or any “issuer free writing prospectus” is being used to solicit offers to buy the 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 Representatives will furnish to the Company) to which Certificates may have been sold by the Representatives 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 Certificates for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representatives reasonably designate and will endeavor to maintain such qualifications in effect so long as required for the distribution of such 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 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 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 Representatives, offer, sell or enter into any agreement to sell (as public debt securities registered under the Securities Act (other than the Certificates) 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 owned by the Company (or rights relating thereto).

(k) The Company shall prepare a final term sheet relating to the offering of the Certificates, containing only information that describes the final terms of the Certificates or the offering in a form consented to by the Representatives 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 Certificates.

5. Certain Covenants of the Underwriters. Each Underwriter represents, warrants and covenants that it has not made and will not make any offer relating to the 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 Certificates or convey final pricing terms thereof that contain only information contained in the Time of Sale Prospectus.

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 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 Representatives 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 Representatives 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 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 Certificates shall be deemed to be in the same respective proportions as the proceeds from the offering of such Certificates received by the Trusts (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 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 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 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 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 Certificates hereunder and the aggregate face amount of the Certificates that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total face amount of the Certificates, the Representatives may make arrangements satisfactory to the Company for the purchase of such 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 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 Certificates with respect to which such default or defaults occurs exceeds 10% of the total face amount of the Certificates and arrangements satisfactory to the Representatives and the Company for purchase of such 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.

If for any reason the purchase of the 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 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 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 Representatives 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 Continental 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 Representatives, 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 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 Representatives, impracticable to market the 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:

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

(iii) If any Refinancing Certificates are issued, each Refinancing Certificateholder shall have the same right (subject to the same terms and conditions) to purchase Certificates pursuant to this Section 4.01(a) (and to receive notice in connection therewith) as the Certificateholders of the Class that such Refinancing Certificates refinanced.

The purchase price with respect to the Applicable Certificates shall be equal to the Pool Balance of the Applicable Certificates, together with accrued and unpaid interest thereon to the date of such purchase, without premium (including Make-Whole Amount), but including any other amounts then due and payable to the Applicable Certificateholders under the Agreement, the Intercreditor Agreement or any Note Document or on or in respect of the Applicable Certificates; provided, however, that no such purchase of Applicable Certificates shall be effective unless the purchaser(s) shall certify to the Trustee that contemporaneously with such purchase, such purchaser(s) is (are) purchasing, pursuant to the terms of the Agreement and the Other Agreements, (A) in the case of any purchase of the Applicable Certificates pursuant to clause (i) above, all of the Applicable Certificates, (B) in the case of any purchase of Applicable Certificates and Class A Certificates pursuant to clause (ii) above, all of the Applicable Certificates and the Class A Certificates or (C) in all other cases, the Applicable Certificates, the Class A Certificates and, if applicable, the Additional Certificates that rank senior to the Additional Certificates held by the purchasing Additional Certificateholder(s). Each payment of the purchase price of the Applicable Certificates referred to in the first sentence hereof shall be made to an account or accounts designated by the Trustee and each such purchase shall be subject to the terms of this Section 4.01. Each Applicable Certificateholder agrees by its acceptance of its Applicable Certificate that (at any time after the occurrence of a Certificate Buyout Event) it will, upon payment from such Class A Certificateholder(s), Additional Certificateholder(s) or Refinancing Certificateholder(s), as the case may be, of the purchase price set forth in the first sentence of this paragraph, (i) forthwith sell, assign, transfer and convey to the purchaser(s) thereof (without recourse, representation or warranty of any kind except for its own acts), all of the right, title, interest and obligation of such Applicable Certificateholder in the Agreement, the Intercreditor Agreement, the Liquidity Facility, the NPA, the Note Documents and all Applicable Certificates held by such Applicable Certificateholder (excluding all right, title and interest under any of the foregoing to the extent such right, title or interest is with respect to an obligation not then due and payable as respects any action or inaction or state of affairs occurring prior to such sale) (and the purchaser shall assume all of such Applicable Certificateholder’s obligations under the Agreement, the Intercreditor Agreement, the Liquidity Facility, the NPA, the Note Documents and all such Applicable Certificates) and (ii) if such purchase occurs after a Record Date relating to any distribution and prior to or on the related Distribution Date, forthwith turn over to the purchaser(s) of its Applicable Certificate all amounts, if any, received by it on account of such distribution. The Applicable Certificates will be deemed to be purchased on the date payment of the purchase price is made notwithstanding the failure of the Applicable Certificateholders to deliver any Applicable Certificates and, upon such a purchase, (I) the only rights of the Applicable Certificateholders will be to deliver the Applicable Certificates to the purchaser(s) and receive the purchase price for such Applicable

Certificates and (II) if the purchaser(s) shall so request, such Applicable Certificateholder will comply with all the provisions of Section 3.04 of the Basic Agreement to enable new Applicable Certificates to be issued to the purchaser in such denominations as it shall request.

with the Basic Agreement, the “Agreement”), between the Trustee and the Company, a summary 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 2015-1AA” (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 certain Equipment Notes and all rights of the Trust to receive payments under the Intercreditor Agreement and the Liquidity Facility (the “Trust Property”). Each issue of the Equipment Notes is secured by, among other things, a security interest in an Aircraft owned by the Company.

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 June 1 and December 1 of each year (a “Regular Distribution Date”) commencing June 1, 2016, 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 Equipment Notes 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 Equipment Notes 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 Equipment Notes, 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 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.

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.

THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.
