In addition, each Trustee hereby agrees to cause the Equipment Notes purchased by the related Trust to be registered in the name of the Subordination Agent or its nominee, as agent and trustee for such Trustee, to be held in trust by the Subordination Agent solely for the purpose of facilitating the enforcement of the subordination and other provisions of this Agreement.

(b) Except as otherwise expressly provided in the next succeeding sentence of this Section 2.1(b), all payments to be made by the Subordination Agent hereunder shall be made only from amounts received by it that constitute Scheduled Payments, Special Payments or payments under the Fee Letter, Section 7.1 of the Participation Agreements or Section 4(a)(v) of the Note Purchase Agreement, and only to the extent that the Subordination Agent shall have received sufficient income or proceeds therefrom to enable it to make such payments in accordance with the terms hereof. Each of the Trustees and the Subordination Agent hereby agrees and, as provided in each Trust Agreement, each Certificateholder, by its acceptance of a Certificate and the Liquidity Provider, by entering into the Liquidity Facility, has agreed to look solely to such amounts to the extent available for distribution to it as provided in this Agreement and to the relevant Deposits and that none of the Trustees, Loan Trustees nor the Subordination Agent is personally liable to any of them for any amounts payable or any liability under this Agreement, any Trust Agreement, the Liquidity Facility or such Certificate, except (in the case of the Subordination Agent) as expressly provided herein or (in the case of the Trustees) as expressly provided in each Trust Agreement or (in the case of the Loan Trustees) as expressly provided in any Operative Agreement.

SECTION 2.2. Trust Accounts. (a) Upon the execution of this Agreement, the Subordination Agent shall establish and maintain in its name (i) the Collection Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Trustees, the Certificateholders and the Liquidity Provider and (ii) as a sub-account in the Collection Account, the Special Payments Account as an Eligible Deposit Account, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Trustees, the Certificateholders and the Liquidity Provider.

Upon such establishment and maintenance under Section 3.5(f) hereof, the Cash Collateral Account shall, together with the Special Payments Account and the Collection Account, constitute the “Trust Accounts” hereunder. Without limiting the foregoing, all monies credited to the Trust Accounts shall be, and shall remain, the property of the relevant Trust(s).

(ii) If at any time the Liquidity Facility becomes a Downgraded Facility, the Subordination Agent shall request a Downgrade Drawing thereunder in accordance with Section 3.5(c)(iii), unless the Liquidity Provider or United arranges for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility to the Subordination Agent within 10 days after receiving notice of a Downgrade Event (but not later than the expiration date of the Downgraded Facility).

(iii) Upon the occurrence of any Downgrade Event, unless a Replacement Liquidity Facility is arranged as provided in Section 3.5(c)(ii), the Subordination Agent shall, on the 10th day referred to in Section 3.5(c)(ii) (or if such 10th day is not a Business Day, on the next succeeding Business Day) (or, if earlier, the expiration date of the Downgraded Facility), request a drawing in accordance with and to the extent permitted by the Downgraded Facility (such drawing, a “Downgrade Drawing”) of the Available Amount thereunder. Amounts drawn pursuant to a Downgrade Drawing shall be maintained and invested as provided in Section 3.5(f) hereof. The Liquidity Provider may also arrange for a Replacement Liquidity Provider to issue and deliver a Replacement Liquidity Facility at any time after such Downgrade Drawing so long as such Downgrade Drawing has not been reimbursed in full to the Liquidity Provider.

Amounts drawn pursuant to a Non-Extension Drawing shall be maintained and invested in accordance with Section 3.5(f) hereof.

(e) Issuance of Replacement Liquidity Facility. (i) At any time, United may, at its option, with cause or without cause, arrange for a Replacement Liquidity Facility to replace the Liquidity Facility (including any Replacement Liquidity Facility provided pursuant to Section 3.5(e)(ii) hereof); provided, however, that the Liquidity Provider shall not be replaced by United as the Liquidity Provider prior to the first anniversary of the Issuance Date unless (A) there shall have become due to the Liquidity Provider, or the Liquidity Provider shall have demanded, amounts pursuant to Section 3.01, 3.02 or 3.03 of the Liquidity Facility and the replacement of the Liquidity Provider would reduce or eliminate the obligation to pay such amounts or United determines in good faith that there is a substantial likelihood that the Liquidity Provider will have the right to claim any such amounts (unless the Liquidity Provider waives, in writing, any right it may have to claim such amounts), which determination shall be set forth in a certificate delivered by United to the Liquidity Provider setting forth the basis for such determination and accompanied by an opinion of outside counsel selected by United and reasonably acceptable to the Liquidity Provider verifying the legal conclusions, if any, of such certificate

relating to such basis, provided that, in the case of any likely claim for such amounts based upon any proposed, or proposed change in, law, rule, regulation, interpretation, directive, requirement, request or administrative practice, such opinion may assume the adoption or promulgation of such proposed matter, (B) it shall become unlawful or impossible for the Liquidity Provider (or its Facility Office) to maintain or fund its LIBOR Advances as described in Section 3.10 of the Liquidity Facility, (C) the Liquidity Facility of such Liquidity Provider shall become a Downgraded Facility or a Non-Extended Facility or a Downgrade Drawing or a Non-Extension Drawing shall have occurred under the Liquidity Facility of the Liquidity Provider, (D) the Liquidity Provider shall have breached any of its payment (including, without limitation, funding) obligations under the Liquidity Facility or (E) a Rate Determination Notice has been issued and has not been withdrawn.

(ii) If the Liquidity Provider shall determine not to extend the Liquidity Facility in accordance with Section 3.5(d), then the Liquidity Provider may, at its option, arrange for a Replacement Liquidity Facility to replace the Liquidity Facility during the period no earlier than 40 days and no later than 25 days prior to the then effective Stated Expiration Date of the Liquidity Facility. At any time after a Non-Extension Drawing has been made under the Liquidity Facility, the Liquidity Provider may, at its option, arrange for a Replacement Liquidity Facility to replace the Liquidity Facility under which such Non-Extension Drawing has been made.

(iii) No Replacement Liquidity Facility arranged by United or the Liquidity Provider in accordance with clause (i) or (ii) above or pursuant to Section 3.5(c), respectively, shall become effective and no such Replacement Liquidity Facility shall be deemed the “Liquidity Facility” under the Operative Agreements, unless and until (A) each of the conditions referred to in sub-clauses (iv)(x) and (z) below shall have been satisfied, (B) if such Replacement Liquidity Facility shall materially adversely affect the rights, remedies, interests or obligations of the Class A Certificateholders under any of the Operative Agreements, the Class A Trustee shall have consented, in writing, to the execution and issuance of such Replacement Liquidity Facility and (C) in the case of a Replacement Liquidity Facility arranged by the Liquidity Provider under Section 3.5(e)(ii) or pursuant to Section 3.5(c), such Replacement Liquidity Facility is acceptable to United.

(iv) In connection with the issuance of a Replacement Liquidity Facility, the Subordination Agent shall (x) prior to the issuance of such Replacement Liquidity Facility, obtain written confirmation from each Rating Agency that such Replacement Liquidity Facility will not cause a reduction of any rating then in effect for any Class of Certificates by such Rating Agency (without regard to any downgrading of any rating of the Liquidity Provider being replaced pursuant to Section 3.5(c) hereof), (y) pay all Liquidity Obligations then owing to the replaced Liquidity Provider (which payment shall be made first from available funds in the Cash Collateral Account as described in clause (v) of Section 3.5(f) hereof, and thereafter from any other available source, including, without limitation, a drawing under the Replacement Liquidity Facility) and (z) cause the issuer of the Replacement Liquidity Facility to deliver the Replacement Liquidity Facility to the Subordination Agent, together with a legal opinion opining that such Replacement Liquidity Facility is an enforceable obligation of such Replacement Liquidity Provider.

(v) Upon satisfaction of the conditions set forth in clauses (iii) and (iv) of this Section 3.5(e) with respect to a Replacement Liquidity Facility, (w) the replaced Liquidity Facility shall terminate, (x) the Subordination Agent shall, if and to the extent so requested by United or the Liquidity Provider being replaced, execute and deliver any certificate or other instrument required in order to terminate the replaced Liquidity Facility, shall surrender the replaced Liquidity Facility to the Liquidity Provider being replaced and shall execute and deliver the Replacement Liquidity Facility and any associated Fee Letters, (y) each of the parties hereto shall enter into any amendments to this Agreement necessary to give effect to (1) the replacement of the Liquidity Provider with the Replacement Liquidity Provider and (2) the replacement of the Liquidity Facility with the Replacement Liquidity Facility and (z) the Replacement Liquidity Provider shall be deemed to be the Liquidity Provider with the rights and obligations of the Liquidity Provider hereunder and under the other Operative Agreements and such Replacement Liquidity Facility shall be deemed to be the Liquidity Facility hereunder and under the other Operative Agreements.

(f) Cash Collateral Accounts; Withdrawals; Investments. In the event the Subordination Agent shall draw all available amounts under the Liquidity Facility pursuant to Section 3.5(c), 3.5(d), 3.5(i) or 3.5(k) hereof, or in the event amounts are to be deposited in the Cash Collateral Account pursuant to subclause (A) or (B) of clause “fourth” of Section 3.2, amounts so drawn or to be deposited, as the case may be, shall be deposited by the Subordination Agent in the Cash Collateral Account. All amounts on deposit in the Cash Collateral Account shall be invested and reinvested in Eligible Investments in accordance with Section 2.2(b) hereof.

On each Interest Payment Date (or, in the case of any Special Distribution Date with respect to the distribution of a Special Payment, on such Special Distribution Date), Investment Earnings on amounts on deposit in the Cash Collateral Account (or, in the case of any Special Distribution Date with respect to the distribution of a Special Payment, so long as no Indenture Event of Default shall have occurred and be continuing under any Indenture, such Investment Earnings multiplied by the Section 2.4 Fraction) shall be deposited in the Collection Account (or, in the case of any Special Distribution Date with respect to the distribution of a Special Payment, the Special Payments Account) and applied on such Interest Payment Date (or Special Distribution Date, as the case may be) in accordance with Section 3.2 or 3.3 (as applicable). The Subordination Agent shall deliver a written statement to United and the Liquidity Provider one day prior to each Interest Payment Date and Special Distribution Date setting forth the aggregate amount of Investment Earnings held in the Cash Collateral Account as of such date. In addition, from and after the date funds are so deposited, the Subordination Agent shall make withdrawals from such accounts as follows:

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

for the Class A Certificates) on the Class A Certificates (excluding interest, if any, payable with respect to the Deposits relating to the Class A Trust) and (y) the amount on deposit in the Cash Collateral Account;

(ii) on each date on which the Pool Balance of the Class A Trust shall have been reduced by payments made to the Class A Certificateholders pursuant to Section 3.2 hereof or pursuant to Section 2.03 of the Escrow Agreement, the Subordination Agent shall withdraw from the Cash Collateral Account such amount as is necessary so that, after giving effect to the reduction of the Pool Balance on such date (and any reduction in the amounts on deposit in the Cash Collateral Account resulting from a prior withdrawal of amounts on deposit in the Cash Collateral Account on such date) and any transfer of Investment Earnings from the Cash Collateral Account to the Collection Account or the Special Payments Account on such date, an amount equal to the sum of the Required Amount plus (if on a Distribution Date not coinciding with an Interest Payment Date) Investment Earnings on deposit in the Cash Collateral Account (after giving effect to any such transfer of Investment Earnings) will be on deposit in the Cash Collateral Account and shall first, pay such withdrawn amount to the Liquidity Provider until the Liquidity Obligations owing to the Liquidity Provider shall have been paid in full, and second, deposit any remaining withdrawn amount in the Collection Account;

(iii) if a Replacement Liquidity Facility shall be delivered to the Subordination Agent following the date on which funds have been deposited into the Cash Collateral Account, the Subordination Agent shall withdraw all amounts on deposit in the Cash Collateral Account and shall pay such amounts to the replaced Liquidity Provider until all Liquidity Obligations owed to such Person shall have been paid in full, and shall deposit any remaining amount in the Collection Account; and

(iv) following the payment of Final Distributions with respect to the Class A Certificates, on the date on which the Subordination Agent shall have been notified by the Liquidity Provider that the Liquidity Obligations owed to the Liquidity Provider have been paid in full, the Subordination Agent shall withdraw all amounts on deposit in the Cash Collateral Account and shall deposit such amount in the Collection Account.

(g) Reinstatement. With respect to any Interest Drawing under the Liquidity Facility, upon the reimbursement of the Liquidity Provider for all or any part of the amount of such Interest Drawing, together with any accrued interest thereon, the Available Amount shall be reinstated by an amount equal to the amount of such Interest Drawing so reimbursed to the Liquidity Provider but not to exceed the Stated Amount; provided, however, that the Liquidity Facility shall not be so reinstated in part or in full at any time if (x) both a Performing Note Deficiency exists and a Liquidity Event of Default shall have occurred and be continuing with respect to the Liquidity Facility or (y) a Final Drawing, a Non-Extension Drawing, a Downgrade Drawing or a Special Termination Drawing shall have occurred with respect to the Liquidity Facility or an Interest Drawing shall have been converted into a Final Drawing. In the event that (i) funds are withdrawn from the Cash Collateral Account pursuant to clause (i) or (ii) of Section 3.5(f) hereof or (ii) the Liquidity Facility shall become a Downgraded Facility or a Non-Extended Facility at a time when unreimbursed Interest Drawings under the Liquidity Facility have reduced the Available Amount thereunder to zero, then funds received

by the Subordination Agent at any time other than (x) any time when a Liquidity Event of Default shall have occurred and be continuing with respect to the Liquidity Facility and a Performing Note Deficiency exists or (y) any time after a Final Drawing shall have occurred with respect to the Liquidity Facility or an Interest Drawing shall have been converted into a Final Drawing, shall be deposited in the Cash Collateral Account as and to the extent provided in clause “fourth” of Section 3.2 and applied in accordance with Section 3.5(f) hereof.

Amounts drawn pursuant to a Final Drawing shall be maintained and invested in accordance with Section 3.5(f) hereof.

(j) Adjustments of Stated Amount. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance with respect to the Class A Certificates or otherwise, the Stated Amount shall automatically be adjusted to an amount equal to the Required Amount (as calculated by the Subordination Agent after giving effect to such payment).

(k) Special Termination Drawing. Upon receipt from the Liquidity Provider of a Special Termination Notice, the Subordination Agent shall, not later than the date specified in such Special Termination Notice, in accordance with the terms of the Liquidity Facility, request a drawing under the Liquidity Facility of all available and undrawn amounts thereunder (a “Special Termination Drawing”). Amounts drawn pursuant to a Special Termination Drawing shall be maintained and invested in accordance with Section 3.5(f) hereof.

(l) Relation to Subordination Provisions. Interest Drawings under the Liquidity Facility and withdrawals from the Cash Collateral Account, in each case, in respect of interest on the Class A Certificates, will be distributed to the Class A Trustee, notwithstanding Section 3.2 hereof.

(m) Assignment of Liquidity Facility. The Subordination Agent agrees not to consent to the assignment by the Liquidity Provider of any of its rights or obligations under the Liquidity Facility or any interest therein, unless (i) United shall have consented to such assignment and (ii) each Rating Agency shall have provided a Ratings Confirmation in respect of such assignment; provided, that the Subordination Agent shall consent to such assignment if the conditions in the foregoing clauses (i) and (ii) are satisfied, and the foregoing is not intended to and shall not be construed to limit the rights of the initial Liquidity Provider under Section 3.5(e)(ii).

ARTICLE IV

EXERCISE OF REMEDIES

SECTION 4.1. Directions from the Controlling Party. (a) (i) Following the occurrence and during the continuation of an Indenture Event of Default under any Indenture, the Controlling Party (except as otherwise provided in Section 2.6(d)) shall direct the Subordination Agent, as the holder of Equipment Notes issued under such Indenture, which in turn shall direct the Loan Trustee under such Indenture, in the exercise of remedies available to the holder of such Equipment Notes, including, without limitation, the ability to vote all such Equipment Notes held by the Subordination Agent in favor of Accelerating such Equipment Notes in accordance with the provisions of such Indenture. If the Equipment Notes issued pursuant to any Indenture and held by the Subordination Agent have been Accelerated following an Indenture Event of Default with respect thereto, the Controlling Party may direct the Subordination Agent to sell, assign, contract to sell or otherwise dispose of and deliver all (but not less than all) of such Equipment Notes to any Person at public or private sale, at any location at the option of the Controlling Party, all upon such terms and conditions as it may reasonably deem advisable in accordance with applicable law.

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

(iii) Notwithstanding the foregoing, so long as any Certificates remain Outstanding, during the period ending on the date which is nine months after the earlier of (x) the Acceleration of the Equipment Notes issued pursuant to any Indenture and (y) the occurrence of a United Bankruptcy Event, without the consent of each Trustee, no Aircraft subject to the Lien of such Indenture or such Equipment Notes may be sold if the net proceeds from such sale would be less than the Minimum Sale Price for such Aircraft or such Equipment Notes.

(iv) Upon the occurrence and during the continuation of an Indenture Event of Default under any Indenture, the Subordination Agent will obtain three desktop appraisals from the Appraisers selected by the Controlling Party setting forth the current market value, current lease rate and distressed value (in each case, as defined by the International Society of Transport Aircraft Trading or any successor organization) of the Aircraft subject to such Indenture (each such appraisal, an “Appraisal” and the current market value appraisals being referred to herein as the “Post-Default Appraisals”). For so long as any Indenture Event of Default shall be continuing under any Indenture, and without limiting the right of the Controlling Party to request more frequent Appraisals, the Subordination Agent will obtain updated Appraisals on the date that is 364 days from the date of the most recent Appraisal (or if a United Bankruptcy Event shall have occurred and is continuing, on the date that is 180 days from the date of the most recent Appraisal). The Subordination Agent shall promptly deliver copies of the Appraisals to the Liquidity Provider.

(b) Following the occurrence and during the continuance of an Indenture Event of Default under any Indenture, the Controlling Party shall take such actions as it may reasonably deem most effectual to complete the sale or other disposition of the relevant Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment, contract to sell or other disposition, the Controlling Party may maintain or cause the Subordination Agent to maintain possession of such Equipment Notes and continue to apply monies received in respect of such Equipment Notes in accordance with Article III hereof. In addition, in lieu of such sale, assignment, contract to sell or other disposition, or in lieu of such maintenance of possession, the Controlling Party may, subject to the terms and conditions of the related Indenture, instruct the Loan Trustee under such Indenture to foreclose on the Lien on the related Aircraft or to take any other remedial action permitted under such Indenture or under any applicable law.

(c) If following a United Bankruptcy Event and during the pendency thereof, the Controlling Party receives a proposal from or on behalf of United to restructure the financing of any one or more of the Aircraft, the Controlling Party shall promptly thereafter give the Subordination Agent and each Trustee notice of the material economic terms and conditions of such restructuring proposal whereupon the Subordination Agent acting on behalf of each Trustee shall endeavor using reasonable commercial efforts to make such terms and conditions of such restructuring proposal available to all Certificateholders (whether by posting on DTC’s Internet board or otherwise). Thereafter, neither the Subordination Agent nor any Trustee, whether acting on instructions of the Controlling Party or otherwise, may, without the consent of each Trustee, enter into any term sheet, stipulation or other agreement (whether in the form of an adequate protection stipulation, an extension under Section 1110(b) of the Bankruptcy Code or otherwise) to effect any such restructuring proposal with or on behalf of United unless and until the material economic terms and conditions of such restructuring shall have been made available to all Certificateholders for a period of not less than 15 calendar days (except that such requirement shall not apply to any such term sheet, stipulation or other agreement that is entered into on or prior to the expiry of the 60-Day Period and that is effective for a period not longer than three months from the expiry of the 60-Day Period). In the event that any Certificateholder gives irrevocable notice of the exercise of its right to purchase all (but not less than all) of the Class A Certificates pursuant to the applicable Trust Agreement prior to the expiry of the 15-day notice period specified above, the Controlling Party may not direct the Subordination Agent or any Trustee to enter into any such restructuring proposal with respect to any of the Aircraft unless and until such Certificateholder shall fail to purchase the Class A Certificates on the date that it is required to make such purchase.

SECTION 4.2. Remedies Cumulative. Each and every right, power and remedy given to the Trustees, the Liquidity Provider, the Controlling Party or the Subordination Agent specifically or otherwise in this Agreement shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may, subject always to the terms and conditions hereof, be exercised from time to time and as often and in such order as may be deemed expedient by any Trustee, the Liquidity Provider, the Controlling Party or the Subordination Agent, as appropriate, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. No delay or omission by any Trustee, the Liquidity Provider, the Controlling Party or the Subordination Agent in the exercise of any

right, remedy or power or in the pursuit of any remedy shall impair any such right, power or remedy or be construed to be a waiver of any default or to be an acquiescence therein.

SECTION 4.3. Discontinuance of Proceedings. In case any party to this Agreement (including the Controlling Party in such capacity) shall have instituted any Proceeding to enforce any right, power or remedy under this Agreement by foreclosure, entry or otherwise, and such Proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Person instituting such Proceeding, then and in every such case each such party shall, subject to any determination in such Proceeding, be restored to its former position and rights hereunder, and all rights, remedies and powers of such party shall continue as if no such Proceeding had been instituted.

SECTION 4.4. Right of Certificateholders and the Liquidity Provider to Receive Payments Not to Be Impaired. Anything in this Agreement to the contrary notwithstanding, the right of any Certificateholder (subject to the applicable Trust Agreement) or the Liquidity Provider, respectively, to receive payments hereunder (including without limitation pursuant to Section 3.2 hereof) when due, or to institute suit for the enforcement of any such payment on or after the applicable Distribution Date, shall not be impaired or affected without the consent of such Certificateholder or the Liquidity Provider, respectively.

SECTION 4.5. Undertaking for Costs. In any Proceeding for the enforcement of any right or remedy under this Agreement or in any Proceeding against any Controlling Party or the Subordination Agent for any action taken or omitted by it as Controlling Party or Subordination Agent, as the case may be, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. The provisions of this Section do not apply to a suit instituted by the Subordination Agent, the Liquidity Provider or a Trustee or a suit by Certificateholders holding more than 10% of the original principal amount of any Class of Certificates.

indirectly modify or supersede, or otherwise conflict with, Section 2.2(b), Section 2.4, Section 3.2, Section 3.5(e), Section 3.5(f) (other than the last sentence thereof), Section 3.5(l), the last sentence of this Section 9.1(a), Section 9.1(c), the second sentence of Section 10.6 or this proviso (collectively, the “United Provisions”) or (y) otherwise adversely affect the interests of a potential Replacement Liquidity Provider or of United with respect to its ability to replace the Liquidity Facility or with respect to its payment obligations under any Operative Agreement or (B) is made pursuant to the last sentence of this Section 9.1(a) or pursuant to Section 9.1(c), then such supplement, amendment or modification shall not be effective without the additional written consent of United. Notwithstanding the foregoing, (A) without the consent of each Class A Certificateholder and the Liquidity Provider, no supplement, amendment or modification of this Agreement may reduce the percentage of the interest in the Class A Trust necessary to consent to modify or amend any provision of this Agreement or to waive compliance therewith and (B) without the prior written consent of the Liquidity Provider, no amendment, supplement, modification or waiver of any of the provisions of this Agreement may alter or modify (i) Section 2.4 or Section 3.2 (except as expressly provided in Section 9.1(c) but in no event shall any such alteration or modification adversely affect the Liquidity Provider), (ii) to the extent such Section relates to the rights or obligations of the Liquidity Provider, Section 2.6(c) or (iii) to the extent such Section relates to the rights or obligations of the Liquidity Provider, Section 3.5 (except as provided in the last sentence of this Section 9.1(a)).

If the Replacement Liquidity Facility for the Liquidity Facility in accordance with Section 3.5(e) hereof is to be comprised of more than one instrument as contemplated by the definition of the term “Replacement Liquidity Facility”, then each of the parties hereto agrees to amend this Agreement to incorporate appropriate mechanics for multiple Liquidity Facilities for an individual Trust.

(b) In the event that the Subordination Agent, as the registered holder of any Equipment Notes, receives a request for the giving of any notice or for its consent to any amendment, supplement, modification, consent or waiver under such Equipment Notes, the Indenture pursuant to which such Equipment Notes were issued, or the related Participation Agreement or other related document, (i) if no Indenture Event of Default shall have occurred and be continuing with respect to such Indenture, the Subordination Agent shall request directions with respect to each series of such Equipment Notes from the Trustee of the Trust which holds such Equipment Notes and shall vote or consent in accordance with the directions of such Trustee, and (ii) if any Indenture Event of Default shall have occurred and be continuing with respect to such Indenture, the Subordination Agent will exercise its voting rights with respect to such Equipment Notes as directed by the Controlling Party (subject to Sections 4.1 and 4.4 hereof); provided that no such amendment, modification or waiver shall, without the consent of each affected Certificateholder and the Liquidity Provider, reduce the amount of principal or interest payable by United under any Equipment Note or change the time of payments or method of calculation of any amount under any Equipment Note.

(c) After the Deposit Period Termination Date, at any time and from time to time, a single additional series of Equipment Notes (the “Additional Equipment Notes”) may be issued under Section 2.02 of one or more of the Indentures subject to the terms and conditions of this Section 9.1(c); provided that (i) the Additional Equipment Notes are subordinated in right of payment to the Series A Equipment Notes under

each Indenture and (ii) no more than one series of Additional Equipment Notes may be outstanding at any time. If a series of Additional Equipment Notes is issued under any Indenture, such series of Additional Equipment Notes shall be issued to a new pass through trust (the “Additional Trust”) that issues a class of pass through certificates (the “Additional Certificates”) to certificateholders (the “Additional Certificateholders”) pursuant to a pass through trust agreement (the “Additional Trust Agreement”) with a trustee (the “Additional Trustee”). On each Distribution Date, no distributions or other cash payments may be made on or in respect of the Additional Certificates unless and until the Expected Distributions with respect to the Class A Certificates on such Distribution Date have been made in full; provided that, the Additional Trustee shall be reimbursed on a pari passu basis with the Class A Trustee for any amounts of the nature described in clause (i) of clause “first” of Section 3.2 hereof but solely to the extent such amounts (x) constitute ordinary administrative expenses (and for the avoidance of doubt, “ordinary administrative expenses” shall not include any costs or expenses (including any costs of counsel) incurred by the Additional Trustee related to enforcement under any of the Operative Agreements) and (y) have been actually incurred by the Additional Trustee under the Additional Trust Agreement.

In the case of the issuance of any Additional Certificates, this Agreement shall be amended by written agreement of United and the Subordination Agent to provide for the subordination of the Additional Certificates to the Administration Expenses, the Liquidity Obligations and the Class A Certificates. Any and each such issuance and the amendment of this Agreement as provided below shall require a Ratings Confirmation and shall not materially adversely affect the Class A Trustee. This Agreement shall be amended by written agreement of United and the Subordination Agent to give effect to the issuance of any Additional Certificates subject to the following terms and conditions:

(i) the Additional Trustee shall be added as a party to this Agreement;

(ii) the definitions of “Certificate”, “Class”, “Equipment Notes”, “Final Legal Distribution Date”, “Trust”, “Trust Agreement” and “Controlling Party” (and such other applicable definitions) shall be revised, as appropriate, to reflect the issuance of the Additional Certificates (and the subordination thereof);

(iii) the Additional Certificates shall not have the benefit of any credit support similar to the Liquidity Facility;

(iv) the Additional Certificates may not be issued to United but may be issued to any of United’s Affiliates so long as such Affiliate shall have bankruptcy remote and special purpose provisions in its certificate of incorporation or other organizational documents and any subsequent transfer of the Additional Certificates to any Affiliate of United shall be similarly restricted;

(v) the provisions of this Agreement governing payments with respect to Certificates and related notices, including Sections 2.4, 3.1 and 3.2, shall be revised to provide for distributions on the Additional Certificates after payment of the Administration Expenses, the Liquidity Obligations and the Class A Certificates; and

(vi) the scheduled payment dates for such series of Additional Equipment Notes shall be on the Regular Distribution Dates.

The issuance of the Additional Certificates in compliance with all of the foregoing terms of this Section 9.1(c) shall not require the consent of the Class A Trustee or the holders of the Class A Certificates. The Liquidity Provider hereby agrees and confirms that it shall be deemed to consent to any issuance and amendment in accordance with this Section 9.1(c).

SECTION 9.2. Subordination Agent Protected. If, in the reasonable opinion of the institution acting as the Subordination Agent hereunder, any document required to be executed pursuant to the terms of Section 9.1 affects any right, duty, immunity or indemnity with respect to it under this Agreement or the Liquidity Facility, the Subordination Agent may in its discretion decline to execute such document.

SECTION 9.3. Effect of Supplemental Agreements. Upon the execution of any amendment, consent or supplement hereto pursuant to the provisions hereof, this Agreement shall be and be deemed to be and shall be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Agreement of the parties hereto and beneficiaries hereof shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental agreement shall be and be deemed to be and shall be part of the terms and conditions of this Agreement for any and all purposes. In executing or accepting any supplemental agreement permitted by this Article IX, the Subordination Agent shall be entitled to receive, and shall be fully protected in relying upon, an opinion of counsel stating that the execution of such supplemental agreement is authorized or permitted by this Agreement.

SECTION 9.4. Notice to Rating Agencies. Promptly upon receipt of any amendment, consent, modification, supplement or waiver contemplated by this Article IX and prior to taking any action required to be taken thereunder, the Subordination Agent shall send a copy thereof to each Rating Agency.
