 WHEREAS, as of the Transfer Date, in the case of each Aircraft, the Company will have issued pursuant to an Indenture, on a recourse
basis, Equipment Notes to finance a portion of the purchase price of such Aircraft; 
 WHEREAS, as of the Transfer Date,
the Related Trustee will assign, transfer and deliver all of such trustee’s right, title and interest to the trust property held by the Related Trustee to the Trustee pursuant to the Assignment and Assumption Agreement (as defined below);

 WHEREAS, the Trustee, effective only, but automatically, upon execution and delivery of the Assignment and Assumption
Agreement, will be deemed to have declared the creation of the United Air Lines Pass Through Trust 2009-2B-S (the “Applicable Trust”) for the benefit of the Applicable Certificateholders, and the initial Applicable
Certificateholders as the grantors of the Applicable Trust, by their respective acceptances of the Applicable Certificates, join in the creation of the Applicable Trust with the Trustee; 
 WHEREAS, all Certificates deemed issued by the Applicable Trust will evidence fractional undivided interests in the Applicable Trust
and will convey no rights, benefits or interests in respect of any property other than the Trust Property except for those Certificates to which an Escrow Receipt has been affixed; 
 WHEREAS, upon the execution and delivery of the Assignment and Assumption Agreement, all of the conditions and requirements necessary
to make this Trust Supplement, when duly executed and delivered, a valid, binding and legal instrument in accordance with its terms and for the purposes herein expressed, have been done, performed and fulfilled, and the execution and delivery of

conditions applicable to the Applicable Certificates are as follows: 
 (a) The aggregate principal amount of the Applicable
Certificates that shall be authenticated under the Agreement (except for Applicable Certificates authenticated and delivered under Sections 3.03, 3.04, 3.05 and 3.06 of the Basic Agreement) is $112,606,000. 
 (b) The Regular Distribution Dates with respect to any payment of Scheduled Payments means January 15 and July 15 of each year,

Applicable Certificates or an interest therein is exempt from the prohibited transaction restrictions of ERISA and the Code pursuant to one or more prohibited transaction statutory or administrative exemptions. In addition, the Applicable
Certificates will bear a legend regarding ERISA compliance matters. 
 (ii) The Applicable Certificates shall be
Book-Entry Certificates and shall be subject to the conditions set forth in the Letter of Representations between the Company and the Clearing Agency attached as Exhibit B to the Related Pass Through Trust Supplement. 
 (f) The “Participation Agreements” as defined in this Trust Supplement are the “Note Purchase Agreements” referred to in
the Basic Agreement.

(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 Escrow Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity Facility, the Note Purchase Agreement, the Note Documents and all Applicable Certificates and Escrow Receipts 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 Escrow Agreement, the Deposit Agreement, the Intercreditor Agreement, the Liquidity Facility,
the Note Purchase Agreement, the Note Documents and all such Applicable Certificates and Escrow Receipts), (ii) if such purchase occurs after a record date specified in Section 2.03(a) of the Escrow Agreement relating to the distribution

connection with the issuance of any such new Applicable Certificates shall be borne by the purchaser thereof.

however, that enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors generally and (ii) general principles of equity. 
 Section 5.05. Trustee Liens. The Trustee in its individual capacity agrees, in addition to the agreements contained in
Section 7.17 of the Basic Agreement, that it will at its own cost and expense promptly take any action as may be necessary to duly discharge and satisfy in full any Trustee’s Liens on or with respect to the Trust Property which is

of transfer or exchange. 
 Upon surrender for registration of transfer of any Applicable Certificate at the Corporate Trust

exchange is entitled to receive. Every Applicable Certificate presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the
Registrar duly executed by the Applicable Certificateholder thereof or its attorney duly authorized in writing.

sole investment discretion with respect to each such investor account and that it has full power to make the foregoing acknowledgments, representations and agreements on behalf of each such investor account; 
 (vii) Acknowledge that the foregoing restrictions apply to holders of beneficial interests in the Applicable Certificates as

of Borrowing, in accordance with the Borrower’s payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the Liquidity Provider shall not thereafter be
obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of

  

 9 

 [Revolving Credit Agreement (2009-2A)] 
  
 
Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in Section 2.02(e), the Liquidity Provider shall have fully discharged its
obligations hereunder with respect to such Advance and an event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c), (d) or (g) hereof to fund the Class A Cash
Collateral Account, the Liquidity Provider shall have no interest in or rights to the Class A Cash Collateral Account, the funds constituting such Advance or any other amounts from time to time on deposit in the Class A Cash Collateral
Account; provided that the foregoing shall not affect or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.5(e) or (f) of the Intercreditor Agreement, and provided further,
that the foregoing shall not affect or impair the rights of the Liquidity Provider to provide written instructions with respect to the investment and reinvestment of amounts in the Class A Cash Collateral Account to the extent provided in
Section 2.2(b) of the Intercreditor Agreement. By paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested. 
 (g) A
Special Termination Advance shall be made in a single Borrowing upon the receipt by the Borrower of a Special Termination Notice from the Liquidity Provider pursuant to Section 6.01(b), by delivery to the Liquidity Provider of a written and
completed Notice of Borrowing in substantially the form of Annex VII, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used solely to fund the Class A Cash
Collateral Account (in accordance with Section 3.5(f) and Section 3.5(k) of the Intercreditor Agreement). 
 Section
2.03 Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the Fee Letter applicable to this Agreement. 
 Section 2.04 Automatic Reductions and Termination of the Maximum Commitment. 
 (a)
Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result of a reduction in the Pool Balance of the Class A Certificates or otherwise, the Maximum Commitment shall automatically be reduced to
an amount equal to such reduced Required Amount (as calculated by the Borrower); provided that on the first Regular Distribution Date, the Maximum Commitment shall automatically be reduced to the then Required Amount. The Borrower shall give notice
of any such automatic reduction of the Maximum Commitment to the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment.

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

 [Revolving Credit Agreement (2009-2A)] 
  
 Section 2.05 Repayments of Interest Advances, the Special
Termination Advance or the Final Advance. Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby
waived by the Borrower), to pay, or to cause to be paid, to the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance, the Special Termination Advance or the Final Advance, an amount equal to (a) the
amount of such Advance (any such Advance, until repaid, is referred to herein as an “Unpaid Advance”) (if multiple Interest Advances are outstanding any such repayment to be applied in the order in which such Interest
Advances have been made, starting with the earliest), plus (b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider shall make a Provider Advance at any
time after making one or more Interest Advances which shall not have been repaid in accordance with this Section 2.05 or (ii) this Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed
Interest Advances have reduced the Maximum Available Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or an Applied Non-Extension
Advance, as the case may be, for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for
the purposes of Section 2.06(b)); provided, further, that amounts in respect of a Special Termination Advance withdrawn from the Class A Cash Collateral Account for the purpose of paying interest on the Class A
Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being an “Applied Special Termination Advance”) shall thereafter (subject to Section 2.06(b)) be treated as
an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; and provided, further, that if, following the making of a Special Termination Advance, the Liquidity
Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01(a), such Special Termination Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable
Liquidity Rate for interest payable thereon and the obligation for repayment thereof and as an Applied Special Termination Advance for purposes of Section 2.6(c) of the Intercreditor Agreement. The Borrower and the Liquidity Provider agree that
the repayment in full of each Interest Advance, Special Termination Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider. 
 Section 2.06 Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider Advance shall be deposited
in the Class A Cash Collateral Account, invested and withdrawn from the Class A Cash Collateral Account as set forth in Sections 3.5(c), (d), (e) and (f) of the Intercreditor Agreement. Subject to Sections 2.07 and
2.09, the Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such Provider Advance as
provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class A Cash Collateral Account for the purpose of paying interest on the Class A Certificates in accordance with
Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being (y) in the case of a Downgrade Advance, an “Applied Downgrade Advance” and (z) in the case of a Non-Extension Advance, an
“Applied Non-Extension Advance” and, together with an Applied Downgrade Advance, an “Applied Provider Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance
under this Agreement for purposes of determining the

  

 11 

 [Revolving Credit Agreement (2009-2A)] 
  
 
Applicable Liquidity Rate for interest payable thereon and the dates on which such interest is payable; provided further, however, that if, following the making of a Provider Advance, the
Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01(a) hereof, such Provider Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the
Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and as an Applied Downgrade Advance or Applied Non-Extension Advance, as the case may be, for the purposes of Section 2.6(c) of the Intercreditor
Agreement. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class A Cash Collateral Account on account of a reduction in the Required Amount, the Borrower shall repay to the Liquidity
Provider a portion of the Provider Advances in a principal amount equal to the amount of such reduction, plus interest on the principal amount prepaid as provided in Section 3.07 hereof. 
 (b) At any time when an Applied Provider Advance (or any portion thereof) is outstanding, upon the deposit in the Class A Cash
Collateral Account of any amount pursuant to clause “fourth” of Section 3.2 of the Intercreditor Agreement (any such amount being a “Replenishment Amount”) for the purpose of replenishing or increasing
the balance thereof up to the amount of the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances (and of Provider Advances treated as an Interest Advance for purposes of determining the
Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount (if multiple Applied Provider Advances are outstanding, such Replenishment Amount to be applied in the order in which
such Applied Provider Advances have been made, starting with the earliest) and (ii) the aggregate outstanding principal amount of all Unapplied Provider Advances shall be automatically increased by the amount of such Replenishment Amount.

 (c) At any time when an Applied Special Termination Advance (or any portion thereof) is outstanding, upon the deposit in the
Class A Cash Collateral Account of any amount pursuant to clause “fourth” of Section 3.2 of the Intercreditor Agreement (any such amount being a “Special Termination Replenishment Amount”) for the purpose
of replenishing or increasing the balance thereof up to the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Special Termination Advances (and of Special Termination Advances treated as an Interest
Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Special Termination Replenishment Amount and (ii) the aggregate outstanding principal amount of
all Unapplied Special Termination Advances shall be automatically increased by the amount of such Special Termination Replenishment Amount. 
 (d) Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with Section 3.5(e) of the Intercreditor Agreement, amounts remaining on deposit in the
Class A Cash Collateral Account after giving effect to any Applied Provider Advance or Applied Special Termination Advance on the date of such replacement shall be reimbursed to the replaced Liquidity Provider, but only to the extent such
amounts are necessary to repay in full to the replaced Liquidity Provider all amounts owing to it hereunder. 
  

 12 

 [Revolving Credit Agreement (2009-2A)] 
  
 Section 2.07 Payments to the Liquidity Provider Under the
Intercreditor Agreement. In order to provide for payment or repayment to the Liquidity Provider of any amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.5(f) of the Intercreditor Agreement), shall be paid to the Liquidity
Provider in accordance with the terms thereof. Amounts so paid to, and not required to be returned by, the Liquidity Provider shall be applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the
Intercreditor Agreement and shall discharge in full the corresponding obligations of the Borrower hereunder (or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate). 

Section 2.08 Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided, however, that the failure by the
Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances. 
 Section 2.09 Payments from Available Funds Only. All payments to be made by the Borrower under this Agreement, including, without limitation, Sections 7.05 and 7.07, shall be made only from the amounts that constitute Scheduled
Payments, Special Payments or payments under the Fee Letter, Section 4(a)(v) of the Note Purchase Agreement and Section 7.1 of the Participation Agreements and only to the extent that the Borrower shall have sufficient income or proceeds
therefrom to enable the Borrower to make payments in accordance with the terms hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such
amounts in respect of payments to be made by the Borrower hereunder to the extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally
liable to it for any amounts payable or liability under this Agreement except as expressly provided in this Agreement, the Intercreditor Agreement or any Participation Agreement. Amounts on deposit in the Class A Cash Collateral Account shall
be available to the Borrower to make payments under this Agreement only to the extent and for the purposes expressly contemplated in Section 3.5(f) of the Intercreditor Agreement. 
 Section 2.10 Extension of the Expiry Date; Non-Extension Advance. No earlier than the 45th day and no later than the 30th day prior
to the then effective Expiry Date (unless such Expiry Date is on or after the date that is 15 days after the Final Legal Distribution Date for the Class A Certificates), the Borrower shall request that the Liquidity Provider extend the Expiry
Date to the earlier of (i) the date that is 15 days after the Final Legal Distribution Date for the Class A Certificates and (ii) the date that is the day immediately preceding the 364th day occurring after the last day of the Consent
Period (as hereinafter defined). Whether or not the Borrower has made such request, the Liquidity Provider shall advise the Borrower no earlier than the 30th day (or, if earlier, the date of the Liquidity Provider’s receipt of such
request, if any, from the Borrower) and no later than the 25th day prior to the then effective Expiry Date (such period, the “Consent Period”), whether, in its sole discretion, it agrees to so extend the Expiry Date. If
the Liquidity Provider advises the Borrower on or before the date on which the Consent Period ends that such Expiry Date shall not be so

  

 13 

 [Revolving Credit Agreement (2009-2A)] 
  
 
extended, or fails to irrevocably and unconditionally advise the Borrower on or before the date on which the Consent Period ends that such Expiry Date shall be so extended (and, in each case, if
the Liquidity Provider shall not have been replaced in accordance with Section 3.5(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after the date on which the Consent Period ends (but prior to the then effective Expiry
Date) to request a Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.5(d) of the Intercreditor Agreement. 
 ARTICLE III 
 OBLIGATIONS OF THE BORROWER 
 Section 3.01 Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such amounts as may be necessary to
compensate the Liquidity Provider for any increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any Advances hereunder or its obligation to make any such Advances hereunder, or any reduction in any
amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called
“Additional Costs”), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign laws or regulations (including Regulation D of the Board of Governors of the Federal Reserve
System), or the adoption or making after the date of this Agreement of any interpretations, directives, or requirements applying to a class of banks including the Liquidity Provider under any U.S. federal, state, municipal, or any foreign laws or
regulations (whether or not having the force of law) by any court, central bank or monetary authority charged with the interpretation or administration thereof (a “Regulatory Change”), which: (1) changes the basis of
taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances or such obligation (other than with respect to Excluded Taxes or Indemnified Taxes); or (2) imposes or modifies any reserve, special
deposit, compulsory loan or similar requirements relating to any extensions of credit or other assets of, or any deposits with other liabilities of, the Liquidity Provider (including any such Advances or such obligation or any deposits referred to
in the definition of LIBOR Rate or Market Disruption Base Rate or related definitions). The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policies and applicable legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be
otherwise disadvantageous to the Liquidity Provider. 
 The Liquidity Provider will notify the Borrower of any event occurring
after the date of this Agreement that will entitle the Liquidity Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice
shall describe in reasonable detail the calculation of the amounts owed under this Section; provided, that if the Liquidity Provider fails to give such notice within 180 days after it obtains such knowledge, the Liquidity Provider shall, with
respect to any costs resulting from such event, only be entitled to payment under this Section 3.01 for costs incurred from and after the date 180 days prior to the date the Liquidity Provider does give such notice. Determinations by the
Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining

  

 14 

 [Revolving Credit Agreement (2009-2A)] 
  
 
Advances or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima
facie evidence of the amount owed under this Section. 
 Notwithstanding the preceding two paragraphs, the Liquidity Provider
and the Subordination Agent agree that any permitted assignee or participant of the initial Liquidity Provider which is not a bank, shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of
Section 7.08 hereof). 
 Section 3.02 Capital Adequacy. If (1) the adoption, after the date hereof, of any
applicable governmental law, rule or regulation regarding capital adequacy, (2) any change, after the date hereof, in the interpretation or administration of any such law, rule or regulation by any central bank or other governmental authority
charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider with any applicable guideline or request of general applicability, issued after
the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in clause (2), has the effect of (x) requiring an increase in the amount of
capital required to be maintained by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider and such increase is based upon the Liquidity Provider’s obligations hereunder (including funded obligations) and other
similar obligations or (y) reducing the rate of return on assets or capital of the Liquidity Provider (or such corporation or bank) and such adoption, change or compliance, as the case may be, relates to the Liquidity Provider’s
obligations hereunder (including funded obligations) and similar obligations, the Borrower shall, subject to the provisions of the next paragraph, pay to the Liquidity Provider from time to time such additional amount or amounts as are necessary to
compensate the Liquidity Provider for such portion of such increase as shall be reasonably allocable to the Liquidity Provider’s obligations to the Borrower hereunder. 
 The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts
owed under this Section; provided, that if the Liquidity Provider fails to give such notice within 180 days after it obtains such knowledge, the Liquidity Provider shall, with respect to any costs resulting from such event, only be entitled to
payment under this Section 3.02 for costs incurred from and after the date 180 days prior to the date the Liquidity Provider does give such notice. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of
any increase in the amount of capital required to be maintained by the Liquidity Provider and of the amount allocable to the Liquidity Provider’s obligations to the Borrower hereunder shall be prima facie evidence of the amounts owed under this
Section, absent manifest error. 
 Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination
Agent agree that any permitted assignee or participant of the initial Liquidity Provider which is not a bank, shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof).

  

 15 

 [Revolving Credit Agreement (2009-2A)] 
  
 Section 3.03 Payments Free of Deductions. (a) Unless
required by applicable law, all payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future Taxes of any nature whatsoever now or hereafter imposed, levied,
collected, withheld or assessed. If any Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, (i) the Borrower shall within the time prescribed therefor by applicable law pay to the
appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time
or times and in the manner prescribed by applicable law, and (ii) in the case of Taxes, other than Excluded Taxes (such non-excluded Taxes being referred to herein, collectively, as “Indemnified Taxes” and each,
individually, as a “Indemnified Tax”), the amounts so payable to the Liquidity Provider shall be increased to the extent necessary to yield to the Liquidity Provider (after payment of all Taxes) interest or any other such
amounts payable under this Agreement at the rates or in the amounts specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if making such change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise
disadvantageous to the Liquidity Provider. From time to time upon the reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower such original Internal Revenue Service Forms (including W-8BEN, W-8ECI or W-9), as
appropriate with respect to Liquidity Provider, or any successor or other form prescribed by the Internal Revenue Service, certifying as to any available exemption from or reduction in the rate of United States withholding tax on payments pursuant
to this Agreement. Within 30 days after the date of each payment hereunder, the Borrower shall furnish to the Liquidity Provider the original or a certified copy of (or other documentary evidence of) the payment of the Indemnified Taxes applicable
to such payment. 
 (b) Unless required by applicable law, all payments (including, without limitation, Advances) made by the
Liquidity Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the
Liquidity Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable
under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such
Taxes) will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to
the Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment. 
 (c) If any exemption from, or reduction in the rate of, any Taxes is reasonably available to the Borrower to establish that payments under this Agreement are exempt from (or entitled to a reduced rate of)
tax, the Borrower shall deliver to the Liquidity Provider such form or forms and such other evidence of the eligibility of the Borrower for such exemption or reduction as the

  

 16 

 [Revolving Credit Agreement (2009-2A)] 
  
 
Liquidity Provider may reasonably identify to the Borrower as being required as a condition to exemption from, or reduction in the rate of, any Taxes. 
 Section 3.04 Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider under this Agreement so as
to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America, to the Liquidity Provider
in immediately available funds, by wire transfer to the account of Goldman Sachs Bank USA at Citibank, N.A., New York, ABA No. 021000089, Account No. 30627664, Reference: United Air Lines, Attn: Bank Loan Operations, or to such other
account as the Liquidity Provider may from time to time direct the Borrower. 
 Section 3.05 Computations. All
computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate or the Market Disruption Base Rate shall be made on the basis of a
year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. 
 Section 3.06 Payment on Non-Business Days. Whenever any payment to be made hereunder to the Liquidity Provider shall be stated to be
due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day without any additional interest (and if so made, shall be deemed to have been made when due). 
 Section 3.07 Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause to be paid, without duplication,
interest on (i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, from and including the date on which the amount
thereof was withdrawn from the Class A Cash Collateral Account to pay interest on the Class A Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied Provider Advance or Applied
Special Termination Advance, the date on which the Class A Cash Collateral Account is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or other amounts or, to the
extent permitted by law, installments of interest on Advances or any such other amount) that is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but excluding the date such
amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount, as the case may be, as in effect for such day, but in
no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07 shall exceed the maximum rate
permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until the total amount of interest
accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect. 
 (b) Except as provided in clause (e) below, each Advance (other than any Unapplied Provider Advance or Unapplied Special Termination
Advance) will be either a Base Rate Advance or a LIBOR Advance as provided in this Section. Each such Advance

  

 17 

 [Revolving Credit Agreement (2009-2A)] 
  
 
will be a Base Rate Advance for the period from the date of its borrowing to (but excluding) the third LIBOR Business Day following the Liquidity Provider’s receipt of the Notice of
Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance. 
 (c) Each LIBOR Advance shall bear interest
during each Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of
principal of such LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid). 
 (d) Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin for such Base Rate Advance, payable in arrears on each Regular Distribution Date and,
in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of interest accrued on the amount of principal repaid). 
 (e) Each outstanding Unapplied Non-Extension Advance, Unapplied Downgrade Advance and Unapplied Special Termination Advance shall bear
interest in an amount equal to the Investment Earnings on amounts on deposit in the Class A Cash Collateral Account plus the Applicable Margin for such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special
Termination Advance, as applicable, on the amount of such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance from time to time, payable in arrears on each Regular Distribution Date. 
 (f) Each amount not paid when due hereunder (whether fees, commissions, expenses or other amounts or, to the extent permitted by applicable
law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% per annum until paid. 
 (g) Each change in the Base Rate shall become effective immediately. The rates of interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the
“Applicable Liquidity Rate”. 
 (h) If at any time the Liquidity Provider shall have determined (which determination
shall be conclusive and binding upon the Borrower, absent manifest error) that, by reason of circumstances affecting the relevant interbank lending market generally, the LIBOR Rate determined or to be determined for such Interest Period will not
adequately and fairly reflect the cost to the Liquidity Provider (as conclusively certified by the Liquidity Provider, absent manifest error) of making or maintaining Advances, the Liquidity Provider shall give facsimile or telephonic notice thereof
(a “Rate Determination Notice”) to the Borrower. Following the receipt of a Rate Determination Notice by the Borrower, the LIBOR Rate shall be the Market Disruption Base Rate until the Interest Period that immediately follows
the withdrawal of such Rate Determination Notice. The Liquidity Provider shall withdraw a Rate Determination Notice given hereunder when the Liquidity Provider determines that the circumstances giving rise to such Rate Determination Notice no longer
apply to the Liquidity Provider. 
  

 18 

 [Revolving Credit Agreement (2009-2A)] 
  
 Section 3.08 Replacement of Borrower. From time to time
and subject to the successor Borrower’s meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and
completed Notice of Replacement Subordination Agent in substantially the form of Annex VI attached hereto (a “Notice of Replacement Subordination Agent”) delivered to the Liquidity Provider by the then Borrower, the successor
Borrower designated therein shall be substituted for the Borrower for all purposes hereunder. 
 Section 3.09 Funding Loss
Indemnification. The Borrower shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss,
cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of:

 (1) Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such
Advance; or 
 (2) Any failure by the Borrower to borrow a LIBOR Advance on the date for borrowing specified in
the relevant notice under Section 2.02. 
 Section 3.10 Illegality. Notwithstanding any other provision in this
Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Liquidity Provider (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for the
Liquidity Provider (or its Lending Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances
(a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the last Interest Period to expire
before the effective date of any such change or request. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policies and applicable legal and regulatory restrictions) to change the jurisdiction of its Lending
Office if making such change would avoid or cure the aforesaid illegality and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

incurred by or asserted against any Liquidity Indemnitee, in any way relating to, resulting from, or arising out of or in connection with any action, suit or proceeding by any third party against such Liquidity Indemnitee and relating to this
Agreement, the Fee Letter, the Intercreditor Agreement or any Financing Agreement; provided, however, that the Borrower 
  

 24 

 [Revolving Credit Agreement (2009-2A)] 
  
 shall not be required to indemnify, protect, defend and hold harmless any
Liquidity Indemnitee in respect of any Expense of such Liquidity Indemnitee to the extent such Expense is (i) attributable to the gross negligence or willful misconduct of such Liquidity Indemnitee or any other Liquidity Indemnitee,
(ii) ordinary and usual operating overhead expense, (iii) attributable to the failure by such Liquidity Indemnitee or any other Liquidity Indemnitee to perform or observe any agreement, covenant or condition on its part to be performed or
observed in this Agreement, the Intercreditor Agreement, the Fee Letter applicable to this Agreement or any other Operative Agreement to which it is a party; or (iv) a Tax. The indemnities contained in Section 7.1 of the Participation
Agreements, and the provisions of Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall survive the termination of this Agreement.

(i) the use which may be made of the Advances or any acts or omissions of the Borrower or any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon,
even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; or (iii) the making of Advances by the Liquidity Provider against delivery of a Notice of Borrowing and other documents which do not
comply with the terms hereof; provided, however, that the Borrower shall have a claim against the Liquidity Provider, and the Liquidity Provider shall be liable to the Borrower, to the extent of any damages suffered by the Borrower
which were the result of (A) the Liquidity Provider’s willful misconduct or negligence in determining whether documents presented hereunder comply with the terms hereof, or (B) any breach by the Liquidity Provider of any of the terms
of this Agreement or the Intercreditor Agreement, including, but not limited to, the Liquidity Provider’s failure to make lawful payment hereunder after the delivery to it by the Borrower of a Notice of Borrowing strictly complying with the
terms and conditions hereof. In no event, however, shall the Liquidity Provider be liable on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or
anticipated savings). 
 (b) Neither the Liquidity Provider nor any of its officers, employees, directors or Affiliates shall be
liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with this Agreement or any Notice of Borrowing delivered
hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or gross negligence (in which event the extent of the Liquidity Provider’s potential liability to the Borrower shall be
limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing. 
 Section 7.07 Costs, Expenses and Taxes. The Borrower agrees to pay, or cause to be paid (A) on the Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket
costs and expenses (including, without limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and recording
of this Agreement, any other Operative Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses (including reasonable counsel fees and expenses) of the
Liquidity Provider in connection with

  

 25 

 [Revolving Credit Agreement (2009-2A)] 
  
 
(i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such
other documents which may be delivered in connection herewith or therewith (whether or not the same shall become effective) or any waiver or consent thereunder (whether or not the same shall become effective) or (iii) any action or proceeding
relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting
the application of funds in the Class A Cash Collateral Account. In addition, the Borrower shall pay any and all recording, stamp and other similar taxes and fees payable or determined to be payable in connection with the execution, delivery,
filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to hold the Liquidity Provider harmless from and against any and all liabilities with respect to or resulting from any delay in paying or
omission to pay such taxes or fees. 
 Section 7.08 Binding Effect; Participations. (a) This Agreement shall be
binding upon and inure to the benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08 and in
Section 3.5(l) of the Intercreditor Agreement) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the
other party, subject to the requirements of Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive
interest payments hereunder) and under the other Operative Agreements to such Persons (other than United and its Affiliates) as the Liquidity Provider may in its sole discretion select, subject to the requirements of Section 7.08(b). No such
granting of participations by the Liquidity Provider, however, will relieve the Liquidity Provider of its obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the
participant or the proposed participant any information that the Borrower is required to deliver or to disclose or is otherwise provided to the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity
Provider’s source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative Agreements to determinations, reserve and capital adequacy requirements, increased costs, reduced receipts,
additional amounts due pursuant to Section 3.03 and the like as they pertain to the Liquidity Provider shall be deemed also to include those of each of its participants that are banks (subject, in each case, to the maximum amount that would
have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the participant, had held the interest participated). 
 (b) If, pursuant to subsection (a) above, the Liquidity Provider sells any participation in this Agreement to any bank or other entity (each, a “Transferee”), the Transferee
shall not be entitled to receive any greater payment under Section 3.01, 3.02 or 3.03 than the Liquidity Provider would have been entitled to receive with respect to the participation sold to such Transferee unless the sale of such
participation is made with the prior written consent of the Borrower and United. A Transferee shall not be entitled to the benefits of Section 3.03 unless the Borrower and United is notified of the participation sold to such Transferee and such
Transferee agrees, for the benefit of the Borrower, to comply with the certification requirements of Section 3.03 as though it were the Liquidity Provider.

  

 26 

 [Revolving Credit Agreement (2009-2A)] 
  
 
Unless the Borrower has received forms or other documents reasonably satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States
federal withholding tax, the Borrower will withhold any such taxes as required by law from such payments at the applicable statutory rate. 
 (c) Notwithstanding the other provisions of this Section 7.08, the Liquidity Provider may assign and pledge all or any portion of the Advances owing to it to any Federal Reserve Bank or the United
States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank, provided that any payment in respect of such assigned Advances
made by the Borrower to the Liquidity Provider in accordance with the terms of this Agreement shall satisfy the Borrower’s obligations hereunder in respect of such assigned Advance to the extent of such payment. No such assignment shall release
the Liquidity Provider from its obligations hereunder. 
 Section 7.09 Severability. Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or non-authorization without invalidating the remaining provisions hereof or
affecting the validity, enforceability or legality of such provision in any other jurisdiction. 
 Section 7.10 GOVERNING
LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. 
 Section 7.11 Submission to Jurisdiction; Waiver of Jury Trial; Waiver of Immunity. (a) Each of the parties hereto hereby
irrevocably and unconditionally: 
 (i) submits for itself and its property in any legal action or proceeding
relating to this Agreement or any other Operative Agreement, or for recognition and enforcement of any judgment in respect hereof or thereof, to the exclusive jurisdiction of the courts of the State of New York, the courts of the United States of
America for the Southern District of New York, and the appellate courts from any thereof; provided, that, in the case United is a debtor in a proceeding under the Bankruptcy Code, each party also submits for itself and its property to the court that
has jurisdiction over the bankruptcy proceedings; 
 (ii) consents that any such action or proceeding may be
brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or
claim the same; 
 (iii) agrees that service of process in any such action or proceeding may be effected by
mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider
shall have been notified pursuant thereto; and 
  

 27 

 [Revolving Credit Agreement (2009-2A)] 
  
 (iv) agrees that nothing herein shall affect the
right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction. 
 (b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT
MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. The Borrower and the Liquidity Provider each
warrant and represent that it has reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED
EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT. 
 Section 7.12 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which counterparts, when so
executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. 
 Section 7.13 Entirety. This Agreement, the Intercreditor Agreement and the other Operative Agreements to which the Liquidity Provider is a party constitute the entire agreement of the parties
hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements of such parties. 
 Section 7.14 Headings. Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose. 
 Section 7.15 Transfer. The Liquidity Provider hereby acknowledges and consents to the Transfer contemplated by the Assignment and
Assumption Agreement. 
 Section 7.16 LIQUIDITY PROVIDER’S OBLIGATION TO MAKE ADVANCES. EXCEPT AS EXPRESSLY SET
FORTH IN THIS AGREEMENT, THE OBLIGATIONS OF THE LIQUIDITY PROVIDER TO MAKE ADVANCES HEREUNDER, AND THE BORROWER’S RIGHTS TO DELIVER NOTICES OF BORROWING REQUESTING THE MAKING OF ADVANCES HEREUNDER, SHALL BE UNCONDITIONAL AND IRREVOCABLE, AND
SHALL BE PAID OR PERFORMED, IN EACH CASE STRICTLY IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT. 
 Section 7.17 Patriot
Act. In compliance with the USA Patriot Act and 31 CFR Part 103.121 and, in the case of a non-U.S. entity, any other similar requirements of the relevant foreign jurisdiction, when requested WTC shall provide to the Liquidity Provider certain
information relating to WTC that the Liquidity Provider may be required to obtain and keep on file, including WTC’s name, address and various identifying documents. 
  

 28 

 [Revolving Credit Agreement (2009-2A)] 
  
 Section 7.18 Fiduciary Duty. The Liquidity Provider and
its Affiliates may have economic interests that conflict with those of WTC, its stockholders and/or its Affiliates. WTC agrees that nothing in the Operative Agreements or otherwise will be deemed to create an advisory, fiduciary or agency
relationship or fiduciary or implied duty between the Liquidity Provider or its Affiliates, on the one hand, and WTC, its stockholders or its Affiliates, on the other. WTC acknowledges and agrees that (a) the transactions contemplated by the
Operative Agreements (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Liquidity Provider and its Affiliates, on the one hand, and WTC, on the other, and (b) in
connection therewith and with the process leading thereto, (i) neither the Liquidity Provider or its Affiliates have assumed an advisory or fiduciary responsibility in favor of WTC, its stockholders or its Affiliates with respect to the
transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether the Liquidity Provider or its Affiliates have advised, are currently advising or will advise WTC,
its stockholders or its Affiliates on other matters) or any other obligation to WTC except the obligations expressly set forth in the Operative Agreements and (ii) each of the Liquidity Provider and its Affiliates is acting solely as principal
and not as the agent or fiduciary of WTC, its management, stockholders, creditors or any other Person. WTC acknowledges and agrees that WTC has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is
responsible for making its own independent judgment with respect to such transactions and the process leading thereto. WTC agrees that it will not claim that the Liquidity Provider or its Affiliates have rendered advisory services of any nature or
respect, or owes a fiduciary or similar duty to WTC, in connection with such transaction or the process leading thereto.

which Advance is requested to be made on                     ,
            . The Interest Advance should be transferred to [name of bank/wire instructions/ABA number] in favor of account number

 (3) The amount of the Interest Advance requested hereby (i) is
