SERVICING AGREEMENT (as amended, modified or supplemented from time to time in accordance with the terms hereof, the “Agreement”) dated as of September 17, 2012 among ▇▇▇▇▇▇ ENGINE SECURITIZATION TRUST II, a Delaware statutory trust (“WEST”), ▇▇▇▇▇▇ LEASE FINANCE CORPORATION, a Delaware corporation incorporated under the laws of Delaware, in its capacity as Servicer (together with its successors and permitted assigns, the “Servicer”) and as the Administrative Agent, and the entities listed on Appendix A hereto which may be added thereto in accordance with Section 6.13 hereof, (the “Subsidiaries”).

For the consideration set forth herein and other good and valuable consideration, the receipt of which is hereby acknowledged, the parties each agree as follows:

ARTICLE 1

DEFINITIONS

SECTION 1.01. Definitions.

The terms used herein have the meaning assigned to them in Schedule A hereto. Unless otherwise defined herein, all capitalized terms used but not defined herein have the meanings assigned to such terms in the Indenture.

ARTICLE 2

APPOINTMENT; SERVICES

SECTION 2.01. Appointment.

(a) WEST and each Subsidiary hereby appoints the Servicer as the exclusive provider of the Services (as defined in Section 2.02 below) to WEST and each Subsidiary in respect of the Engine Assets on the terms and subject to the conditions set forth in this Agreement.

(b) The Servicer hereby accepts such appointment and agrees to perform the Services on the terms and subject to the conditions set forth in this Agreement. In connection with the provision of the Services with respect to the Engine Assets, the Servicer generally shall, where and to the extent practicable and in the case of Services that are not performed by the Servicer directly, contract for or otherwise obtain goods and services from third party providers in the name of, or as disclosed agent for, WEST or the relevant Subsidiary. If the Servicer shall not have contracted for or otherwise obtained such goods and services in the name of, or as disclosed agent for, WEST or the relevant Subsidiary, the Servicer shall use its reasonable efforts to cause WEST or such Subsidiary to be in a position to have direct recourse against any such third party provider providing goods and services for WEST or such Subsidiary for any breaches by such third party provider related to the provision of such goods and services.

(c) WEST hereby warrants and represents to the Servicer that it and each Subsidiary has appointed or will appoint the Administrative Agent to act as its representative with respect to any matter in respect of which WEST or any Subsidiary is required or permitted to take any action pursuant to the terms of this Agreement. Accordingly, in connection with the performance of the Services, unless an Administrative Agent Event of Default shall have occurred and be continuing, or unless earlier notified by WEST that the appointment of the Administrative Agent to act on behalf of WEST and each Subsidiary has not become effective or has been revoked or terminated, the Servicer shall in all cases be entitled to rely on the instructions (or other actions) of the Administrative Agent as representative of WEST and each Subsidiary other than the actions specified in Sections 7.06(a)(i) and 7.06(a)(iv).

SECTION 2.02. Services.

(a) The services to be provided by the Servicer in respect of the Engine Assets (the “Services”) are as set forth in Schedule 2.02(a) and under this Agreement.

(b) Except with respect to the obligations expressly provided herein, in connection with the performance of the Services, the Servicer shall in all cases only be obligated to act upon, and shall be entitled to rely on, the instructions of WEST or, as provided above in Section 2.01(c), the Administrative Agent, on behalf of WEST and each Subsidiary. The Servicer shall not be liable to WEST, any Subsidiary, the Indenture Trustee or any other Person for any act or omission to act taken in accordance with such instructions, except to the extent provided in Section 3.03.

SECTION 2.03. Limitations.

(a) Neither the Servicer nor any of its Affiliates (other than WEST and each Subsidiary) shall assume any WEST Liabilities. In connection with the performance of the Services and its other obligations hereunder, the Servicer shall not be obligated to take or refrain from taking any action which is reasonably likely to (A) violate any Applicable Law, (B) lead to an investigation by any Governmental Authority or (C) expose the Servicer to any liabilities for which, in the Servicer’s good faith opinion, adequate bond or indemnity has not been provided.

(b) WEST and the Subsidiaries shall at all times retain full legal and equitable title to the Engine Assets, notwithstanding the management thereof by the Servicer hereunder.

ARTICLE 3

STANDARD OF CARE; CONFLICTS OF INTEREST; STANDARD OF LIABILITY

SECTION 3.01. Standard of Care.

The Servicer shall perform the Services with reasonable care and diligence at all times as is customary in the Aircraft Engine leasing industry and as if it were the owner of the Engines (the “Servicer Performance Standard”). The Servicer Performance Standard shall be implemented in a manner which is consistent with the reasonable commercial practices of leading international Aircraft Engine operating lessors and is consistent with the Indenture.

SECTION 3.02. Conflicts of Interest.

(a) WEST and each Subsidiary acknowledges and agrees that (i) in addition to managing the Engine Assets under this Agreement, the Servicer may manage, and shall be entitled to manage, from time to time, the separate assets owned by it or its Affiliates (other than WEST and each Subsidiary) and third parties (“Other Assets”); (ii) in addition to the management of the Engine Assets and the Other Assets, the Servicer shall, and shall be entitled to, carry on its commercial businesses, including the financing, purchase or other acquisition, leasing and sale of Aircraft Engines; (iii) in the course of conducting such activities, the Servicer may from time to time have conflicts of interest in performing its duties on behalf of the various entities to whom it provides management services and with respect to the various assets in respect of which it provides management services; and (iv) the Controlling Trustees of WEST have approved the transactions contemplated by this Agreement and desire that such transactions be consummated and, in giving such approval, the Controlling Trustees of WEST have expressly recognized that such conflicts of interest may arise and that when such conflicts of interest arise the Servicer shall perform the Services in accordance with the Servicer Performance Standard and the Servicer Conflicts Standard set forth below in Section 3.02(b).

(b) If conflicts of interest arise regarding the management or remarketing of any Engine Asset, on the one hand, and any Other Asset, on the other hand, the Servicer shall promptly notify WEST and the Indenture Trustee (but in no later than the date on which the next Monthly Report is delivered). The Servicer shall perform the Services in good faith and to the extent such Engine Asset and such Other Asset are substantially similar in terms of objectively identifiable characteristics relevant for purposes of the particular Services to be performed, the Servicer shall not discriminate between such Engine Asset and such Other Asset on an unreasonable basis (the standard set forth in this Section 3.02(b) shall be referred to collectively as the “Servicer Conflicts Standard”).

SECTION 3.03. Standard of Liability.

The Servicer shall not be liable to WEST or any Subsidiary for any Losses arising (i) as a result of an Engine being sold, leased or purchased on less favorable terms than might have been achieved at any time, provided such transactions were entered into on the basis of an arm’s-length commercial decision of the Servicer, or (ii) in respect of the Servicer’s obligation to apply the Servicer Conflicts Standard in respect of its performance of the Services, except, in either case, in the case of willful misconduct, negligence or fraud on the part of the Servicer. The Servicer shall not be liable to WEST or any Subsidiary for any Loss arising as a result of the performance of any of the Servicer’s obligations as Servicer or as a result of any action which the Servicer is requested to take or refrain from taking by WEST (or the Administrative Agent), unless (A) such Loss has arisen as a result of the willful misconduct, negligence or fraud of the Servicer, (B) such Loss has directly resulted from a breach by the Servicer of the express terms and conditions of this Agreement or (C) such Loss is a Loss for which the Servicer has indemnified WEST and its Affiliates and arises as a result of any material misstatements or omissions in any public filing or offering memorandum relating to information on the Engine Assets, the Servicer and the Services provided by the Servicer for disclosure in such public filing or offering memorandum, provided that the Servicer may reasonably rely on information from third parties without incurring liability (the liability standards set forth in this Section 3.03, the “Standard of Liability”).

SECTION 3.04. Waiver of Implied Standard.

Except as expressly stated above in this Article 3, all other warranties, conditions and representations, express or implied, statutory or otherwise, arising under Delaware or New York law or any other Applicable Law in relation to either the skill, care, diligence or otherwise in respect of any Service to be performed hereunder or to the quality or fitness for any particular purpose of any goods are hereby to the fullest extent permitted by Applicable Law excluded and the Servicer shall not be liable in contract, tort or otherwise under Delaware or New York law or any other Applicable Law for any Loss arising out of or in connection with the Services to be supplied pursuant to this Agreement or any goods to be provided or sold in conjunction with such Services.

The Servicer at such times as WEST may reasonably request shall make available to WEST and its Subsidiaries and their agents (including auditors) (A) reports, ledgers, documents, and other records (including computer records), its books and other information related to the Engine Assets or the business of WEST and its Subsidiaries and (B) the officers and employees of the Servicer, subject to their reasonable availability, in each case, to enable WEST and its Subsidiaries to monitor the performance of the Servicer under this Agreement.

SECTION 6.08. Accounts and Cash Arrangements of WEST and the Subsidiaries.

At all times, WEST shall promptly notify the Servicer of any New Account established by or on behalf of WEST or any Subsidiary or otherwise relating to the Engine Assets and of any Existing Account relating to any Aircraft Engine that becomes an Engine after the date of this Agreement and of the closing of any such account in any case not established or closed by the Servicer.

SECTION 6.09. Notification of Bankruptcy.

If WEST or any Subsidiary shall take any action to:

(b) make an assignment for the benefit of its creditors generally;

then WEST shall notify the Servicer, to the extent practicable, of the taking of any such action. If WEST or any Subsidiary becomes aware of the intent or action of any Person (whether a creditor or member of WEST or any Subsidiary) to appoint a trustee in bankruptcy, liquidator, examiner, custodian, sequestrator or receiver, WEST shall promptly notify the Servicer.

SECTION 6.10. Further Assurances.

WEST and each Subsidiary agree that at any time and from time to time upon the written request of the Servicer, it will execute and deliver such further documents and do such further acts and things as the Servicer may reasonably request in order to effect the purposes of this Agreement.

SECTION 6.11. Covenants.

WEST and each Subsidiary covenant with the Servicer that it will conduct its business such that it is a separate and readily identifiable business from, and independent of, the Servicer and any of its Affiliates (it being understood that the financial statements of WEST or any Subsidiary may be consolidated with those of the Servicer or any of its Affiliates, if to do so is required by any Applicable Law or GAAP and that the tax returns of WEST or any Subsidiary may be consolidated with those of the Servicer and any of its Affiliates in accordance with applicable United States tax laws) and further covenant that, during the term of this Agreement:

(i) it will not induce any third party to rely on the creditworthiness of the Servicer in order that such third party will be induced to contract with it;

SECTION 7.02. Instructions by WEST.

WEST may at any time, other than following the delivery of a Default Notice pursuant to Section 4.02 of the Indenture (that has not been withdrawn or rescinded), in which case the Indenture Trustee may, direct the Servicer to limit or terminate any action being taken by it under this Agreement or to take any action authorized or contemplated by this Agreement (including sale or disposal of any Engine) or the applicable Lease and the Servicer shall use commercially reasonable efforts to comply with such directions.

(b) To assist the Administrative Agent in the preparation and review of a proposed Operating Budget and a proposed Asset Expenses Budget for each One Year Period, the Servicer shall provide the Administrative Agent, by the November 1 immediately preceding such One Year Period, information in a form to be agreed from time to time relating to (i) lease rates, (ii) utilization rate, (iii) expected technical expenditures (including any costs to be capitalized) relating to the Engines, (iv) planned sales, (v) costs relating to insurance, legal, consulting and other similar expenses, including anticipated litigation expenses and (vi) such other information related to Engine Expenses as may be requested by the Administrative Agent for purposes of the preparation and review of such budgets, in each case including the assumptions relating thereto.

(c) Based on the information provided by the Servicer to the Administrative Agent in accordance with Section 7.05(b), the Administrative Agent shall prepare and deliver to the Servicer and WEST by the November 30 immediately preceding each One Year Period, a proposed Operating Budget and Asset Expenses Budget for such One Year Period, together with reasonably detailed supporting information and the assumptions underlying such proposed Operating Budget and Asset Expenses Budget.

(d) Following the receipt by the Servicer and WEST of the proposed Operating Budget and Asset Expenses Budget for a One Year Period as provided in Section 7.05(c), the Servicer and the Administrative Agent, on behalf of WEST and the Subsidiaries, shall consult with each other to agree on a final Operating Budget and a final Asset Expenses Budget for such One Year Period, and taking into account such consultation, WEST shall approve and deliver to the Servicer, by the December 20 immediately preceding the commencement of each One Year Period, a final Operating Budget and Asset Expenses Budget for such One Year Period.

(e) If at any time the Servicer reasonably believes that an incurrence of Engine Expenses is reasonably likely to cause actual aggregate Engine Expenses in the Initial Period or any One Year Period, as the case may be, to exceed 125% of the budgeted amount of aggregate Engine Expenses for such period as set forth in the applicable Budget, the Servicer shall not incur such Engine Expense without prior approval by WEST, and such excess payment and approval thereof shall be reported in the Annual Report for the relevant Initial Period or One Year Period, as the case may be.

SECTION 7.06. Transaction Approval Requirements.

(a) The Servicer shall not do any of the following without the express prior written approval of WEST:

(ii) Enter into any new Lease (or any renewal or extension of an existing Lease or other agreement with a Lessee) of any Engine if the Lease does not comply with the requirements of the Indenture.

(iii) Unless provided for in the then applicable Budgets, enter into any contract for the modification or maintenance of any Engine if the costs to be incurred thereunder by WEST or the relevant Subsidiary are not economically justifiable in light of then current and reasonably anticipated market conditions for used Aircraft Engines.

(iv) Subject to Section (e) of Section 4.02 of Schedule 2.02(a), enter into on behalf of WEST or any Subsidiary, any capital commitment or confirm any order or commitment to acquire, or acquire on behalf of WEST or any Subsidiary, Aircraft Engines, except that the Servicer may enter into any such capital commitment or order or commitment to acquire a Replacement Engine or spare parts for an Engine so long as the same is provided for in the then applicable Budgets.

(v) Issue any guarantee on behalf of, or otherwise pledge the credit of WEST or any Subsidiary, other than any guarantee of any Subsidiary obligation by WEST.

(vi) Unless permitted by any other provision of this Section 7.06, enter into any agreement for services to be provided in respect of Engines by third parties the cost of which is to be borne by WEST and the Subsidiaries, except in each case (A) to the extent that the same is an Engine Expense provided for in the then applicable Budgets, or (B) for third party service providers (including legal counsel) that would be used by the Servicer in the ordinary course of the Servicer’s business.

(vii) Incur on behalf of WEST or any Subsidiary any liability (actual or contingent) or cause any such liability (actual or contingent) to be incurred, except for a liability (A) contemplated in the then applicable Budgets, (B) pursuant to a transaction of a type which is subject to another Transaction Approval Requirement which Transaction Approval Requirement is satisfied or is otherwise authorized by such Transaction Approval Requirement or (C) incurred in the ordinary course of the business of WEST and the Subsidiaries.

(b) Any transaction entered into by the Servicer on behalf of WEST and the Subsidiaries shall be on an arm’s-length basis and on market terms, provided that any transaction approved by the Controlling Trustees shall be deemed to satisfy this clause (b).

(c) The actions specified in clauses (a)(i) and (a)(iv) of this Section 7.06 must be approved by a majority of the Controlling Trustees, including the Independent Controlling Trustee.

(d) The transaction approval requirements (the “Transaction Approval Requirements”) set forth in clauses (i) through (vii) of Section 7.06(a) may only be amended by mutual agreement of the parties hereto and with the written consent of the Indenture Trustee (acting at the direction of the Controlling Party), and shall not in any event be amended to reduce or circumscribe the delegation to the Servicer of the level of autonomy, authority and responsibility contemplated by the Transaction Approval Requirements with respect to the performance of the Services. The Servicer shall provide notice to the Indenture Trustee of any amendment to the Transaction Approval Requirements for inclusion of such notice by the Indenture Trustee in the next Annual Report.

(b) WEST and the Subsidiaries acknowledge and agree that amounts payable to or for the benefit of the Servicer under Section 11.01 shall constitute Expenses (subject to the limitation set forth in such definition on indemnification amounts payable to Service Providers).

(c) The Servicer agrees to give WEST prompt notice of any action, claim, demand, discovery of fact, proceeding or suit for which the Servicer intends to assert a right to indemnification under this Agreement; provided, however, that failure to give such notification shall not affect the Servicer’s entitlement to indemnification under this Section 11.01 unless and only to the extent such failure results in actual material prejudice to any of WEST or the Subsidiaries with respect to the action, claim, demand, discovery of fact, proceeding or suit for which a right of indemnification is asserted.

(d) For the avoidance of doubt, all payments owed to the Servicer pursuant to this Article 11 shall be paid from amounts available therefor under Section 3.09 of the Indenture and any recoveries pursuant to insurance policies maintained by WEST or the Servicer in respect of such amounts (after payment of such amounts to the Servicer) shall be deposited in the Collections Account.

(e) The Servicer does hereby assume liability for, and does hereby agree to indemnify, reimburse and hold harmless on an After-Tax Basis, WEST and its Subsidiaries from any and all Losses, to the extent that the Losses exceed recoveries under insurance policies maintained by WEST or the Servicer, that arise (A) as a result of the willful misconduct, negligence or fraud of the Servicer, (B) any Loss which results from a material breach by the Servicer of the express terms and conditions of this Agreement, (C) any Loss arising as a result of any material misstatement or omissions in any public filing or offering memorandum relating to written information on the Engines and the Servicer provided by the Servicer for disclosure in such public filing or offering memorandum, (D) any Loss arising from the violation by Servicer of the Standards of Liability; provided that, notwithstanding anything to the contrary contained in this Agreement, the maximum amount of indemnifiable Losses which may be recovered from the Servicer arising out of or resulting from the causes enumerated in this Section 11.01(e) shall be an amount equal to the sum of the Servicing Fees actually received by the Servicer.

SECTION 11.02. Procedures for Defense of Claims.

(a) If a Third Party Claim is made against the Servicer, the Servicer shall promptly notify WEST of such claim, and the Servicer or WEST (as agreed between them) will undertake the defense thereof. The failure to notify WEST promptly shall not relieve it of its obligations under this Article 11 unless such failure results in actual material prejudice to WEST or any Subsidiary with respect to the action, claim, demand, discovery of fact, proceeding or suit for which a right of indemnification is asserted.

(b) If agreed and accepted by WEST and the Servicer, WEST shall within thirty (30) days undertake the conduct and control, through counsel of its own choosing and at the sole risk and expense of WEST and the Subsidiaries, of the good faith settlement or defense of such claim, and the Servicer shall cooperate fully with WEST in connection therewith; provided that (i) at all times the Servicer shall be entitled to participate in such settlement or defense through counsel chosen by it, and the fees and expenses of such counsel shall be borne by the Servicer, and (ii) none of WEST or any Subsidiary shall be entitled to settle such claims unless it shall have confirmed in writing the obligation of WEST and the Subsidiaries to indemnify the Servicer for the liability asserted in such claim.

(c) So long as WEST is reasonably contesting any such claim in good faith, the Servicer shall fully cooperate with WEST in the defense of such claim as reasonably required by WEST, and WEST shall reimburse the Servicer for reasonable out-of-pocket expenses incurred in connection with such cooperation. Such cooperation shall include the retention and the provision of records and information which are reasonably relevant to such Third Party Claim and the availability on a mutually convenient basis of directors, officers and employees to provide additional information. The Servicer shall not settle or compromise any claim without the written consent of WEST unless the Servicer agrees in writing to forego any and all claims for indemnification from WEST and the Subsidiaries with respect to such claims.

SECTION 11.03. Reimbursement of Costs.

The costs and expenses, including fees and disbursements of counsel (except as provided in Section 11.02(b)(i)) and expenses of investigation, incurred by the Servicer in connection with any Third Party Claim, shall be reimbursed on each Payment Date by WEST upon the submission of evidence reasonably satisfactory to WEST that such expenses have been incurred in the preceding month, without prejudice to WEST’s right to contest the Servicer’s right to indemnification and subject to refund in the event that WEST and the Subsidiaries are ultimately held not to be obligated to indemnify the Servicer.

ARTICLE 1

LEASE SERVICES

SECTION 1.01. Collections and Disbursements. In connection with each Lease of an Engine under which WEST or any Subsidiary is the lessor, the Servicer will:

(a) invoice the Lessee (if contemplated by the applicable Lease) or otherwise arrange, on behalf of WEST or such Subsidiary, for all payments due from the Lessee, including Rental Payments, late payment charges and any payments in respect of Taxes and other payments (including technical, engineering, transportation, insurance and other charges) due under the relevant Lease, direct the Lessee to make such payments to such accounts as are required pursuant to the Indenture and take reasonable steps to enforce the rights and remedies of the Lessor under the Lease in the event of a nonpayment by the relevant due date;

(b) review from time to time, as deemed necessary by the Servicer, the level of Usage Fees and other amounts payable under a Lease (to the extent that such Usage Fees and other amounts may be adjusted under the Lease) and propose to the relevant Lessee or make such adjustments to the Usage Fees and other amounts as are required or that the terms of the relevant Lease and practices that the Servicer believes are prevalent in the Aircraft Engine operating lease market;

(d) subject to the terms of any applicable Engine Document, take such actions as are necessary to apply any payment of any type received from any Lessee on a basis consistent with the terms of such Engine Document, including at the direction of such Lessee to the extent authorized by such Engine Document or as otherwise reasonably determined by the Servicer, and, to the extent that any such payments are made to an account other than the account to which such payment should have been directed pursuant to such terms or direction, to take such further actions as are necessary to give effect to such terms or direction, as applicable; and

(e) provide or arrange for the safekeeping and recording of any letters of credit, guarantees or other credit support (other than cash and cash equivalents) held as part of security deposits or Usage Fees and the timely renewal or drawing on or disbursement thereof as provided under the applicable Engine Document or otherwise in accordance with Section 1.06 of this Schedule 2.02(a).

SECTION 1.02. Maintenance. The Servicer will perform the following technical services relating to the maintenance of the Engines:

(a) Monitor or arrange for the monitoring of, by technical consultants selected by the Servicer, the performance of maintenance obligations by Lessees under all Leases relating to the Engines by including the Engines in the Servicer’s technical audit program (which shall include, if deemed necessary based on the reasonable determination of the Servicer, inspection of each Engine and maintenance of a record of all written reports generated in connection with such inspections) consistent with practices employed from time to time by the Servicer and its Affiliates with respect to their own Aircraft Engines;

(b) Monitor and document the monthly usage of each Engine reported by the Lessee in accordance with the Engine Documents and provide a combined report of such usage to WEST, if requested;

(d) In connection with a termination or expiration of a Lease of an Engine under which WEST or any Subsidiary is the lessor:

(i) arrange for the appropriate technical inspection of such Engine for the purpose of determining if the re-delivery conditions under the Lease have been satisfied;

(ii) maintain a record of the return acceptance certificate and related written materials normally received and retained or generated by the Servicer in connection with such inspection and provide reasonable access to such certificates and written materials to WEST or the relevant Subsidiary;

(iii) on the basis of the final inspection and available records, determine whether the Lessee has complied with the return condition and maintenance requirements of the applicable Lease;

(iv) (A) determine whether the Lessee has satisfied the re-delivery conditions applicable to the Engine specified in the Lease and negotiate any modifications, repairs, refurbishments, inspections or overhauls to or compromises of such conditions that the Servicer deems reasonably necessary or appropriate, (B) negotiate and agree on any financial payment due from the Lessee or from the Lessor under the terms of the Lease; (C) determine the application of any available security deposits, Usage Fees or other payments under the Lease and (D) maintain a record of the satisfaction of such conditions and accept redelivery of the Engine; and

(v) determine the need for and procure any maintenance or refurbishment of the Engine upon redelivery, including compliance with applicable airworthiness directives, service bulletins and other modifications in all cases which the Servicer may deem reasonably necessary or appropriate for the marketing of the Engine consistent with its own practice with respect to its own Aircraft Engines;

(e) Consider and, to the extent the Servicer deems reasonably necessary or appropriate, approve any Lessee-originated modification (including, any such modification in compliance with applicable airworthiness directives, service bulletins and other modifications specified by an Aircraft Engine manufacturer) to any Engine submitted by any Lessee:

(i) to the extent authorized by the terms of the relevant Lease; or

(ii) which the Servicer reasonably determines would not result in a material diminution in value of the Engine;

(f) Estimate the amount (if any) WEST is obliged to contribute pursuant to the provisions of a Lease (taking into account the amount of Usage Fees available with respect to such Lease and the receivables position of the related Lessee) to maintenance work performed, the cost of complying with any modification requirements, airworthiness directives and similar requirements;

(g) Arrange appropriate storage and any required on-going maintenance of any Engine, at the expense of WEST, following termination of a Lease or any re-lease and redelivery of the Engine thereunder and prior to delivery of such Engine to a new lessee or purchaser, consistent with the Servicer’s own practice with respect to its own Aircraft Engines; and

(h) Determine the aggregate amount of the Maintenance and Modification Expenses that are due and payable on each Payment Date or reasonably expected by the Servicer to become due and payable before the next succeeding Payment Date and amounts, the accrual of which would be prudent in light of the size and timing of the anticipated Maintenance and Modification Expenses after such succeeding Payment Date and before the sixth succeeding Payment Date (the “Maintenance Required Amount”). The Servicer shall adjust the Maintenance Required Amount for each successive Payment Date, taking into account additional information as to actual and projected Maintenance and Modification Expenses and Usage Fees paid by Lessees and may re-allocate the accrual of projected Maintenance and Modification Expenses among such Payment Date and the next five succeeding Payment Dates. The Maintenance Required Amount on each Payment Date shall be in a minimum amount of $5 million.

The Servicer shall generally provide the technical/maintenance advisory services set forth in this Section 1.02 of this Schedule 2.02(a) through the use of its own staff, consistent with the Servicer’s own practice with respect to its own Aircraft Engines; provided that it shall utilize third parties to provide such technical/maintenance services where it shall deem appropriate as its own expense with regard to its normal business practices.

(ii) negotiate the insurance provisions of any proposed Lease or other agreement affecting any of the Engines, with such provisions to include such minimum coverage amounts with respect to hull and liability insurance as are consistent with the Servicer’s commercially reasonable practice with respect to its own Aircraft Engines with any differences in such amounts to be notified to WEST by the Servicer;

(iii) monitor the performance of the obligations of Lessees relating to insurance under Leases of any Engines and ensure that appropriate evidence of insurance exists with respect to any Engine and insurance and evidence of insurance is appropriately provided by maintenance facilities providing maintenance work on such Engine paid for by the Servicer;

(iv) to the extent hull and liability insurance is not maintained by any Lessee, assist in arranging, through WEST’s broker, a group aviation insurance program covering the Engines (it being understood that any savings resulting from a group policy covering both Engines and Other Assets shall be shared pro rata based on the Adjusted Appraised Value of the Engines and the net book value of the Other Assets, as determined on a basis consistent with the determination of Adjusted Appraised Value), with such minimum coverage amounts with respect to hull and liability insurance as are consistent with the Servicer’s commercially reasonable practice with respect to its own Aircraft Engines with any differences in such amounts to be notified in writing to WEST and the Indenture Trustee by the Servicer;

(v) arrange, through WEST’s broker, at the expense and written direction of WEST, such political risk insurance for Engines habitually based or registered in those countries in a list to be determined from time to time by WEST and such other insurance related thereto from the sources and with such minimum coverage amounts with respect to hull insurance as are consistent with the Servicer’s commercially reasonable practice with respect to its own Aircraft Engines with any differences in such amounts and the amounts set forth on Schedule 1.03(a) to this Schedule 2.02(a) to be notified to WEST by the Servicer;

(vi) the Servicer will maintain at all times through WEST’s broker, at the direction and expense of WEST, contingent insurance coverage, with such minimum coverage amounts with respect to hull and liability insurance as are set forth on Schedule 1.03(a) to this Schedule 2.02(a), except as notified to WEST by the Servicer;

(vii) advise WEST of any settlement offers received by the Servicer from a Lessee or its insurer with respect to any claim of damage or loss, including a Total Loss, of an Engine and provide WEST with copies of all relevant documentation related thereto and such other additional information and advice from the Lessee’s or the insurer’s agents, brokers or adjusters as WEST may reasonably request; and

(viii) unless WEST notifies the Servicer within five (5) Business Days after WEST is advised of any settlement offer in accordance with clause (vii) that WEST will itself negotiate the settlement offer, the Servicer shall be authorized to accept or continue to negotiate such settlement offer or such advisement and, upon acceptance of a settlement offer, to forward to WEST’s broker the appropriate documentation, including releases and any indemnities required in connection with such releases, to give effect to such settlement offer and procure the execution of such documentation by WEST;

provided, however, that, in each case where insurance is to be obtained by the Servicer through WEST’s broker, such insurance is reasonably available in the relevant insurance market using reasonable sourcing techniques consistent with the techniques for the Servicer’s then current practice for obtaining such insurance. Any decision or action implemented by or on behalf of WEST as a result of the insurance services provided by the Servicer is solely the decision of WEST. The foregoing provisions shall apply to any arrangements in which Persons other than Lessees have possession of, or insurance responsibility for, an Engine.

(b) The Servicer shall provide to WEST such periodic reports regarding insurance matters relating to the Engines as the Servicer shall generate internally or deliver to WEST’s broker from time to time or as WEST shall request.

(c) All insurance provided under this Section 1.03 shall include a provision naming the Indenture Trustee as, in the case of property insurance, loss payee and, in the case of liability insurance, additional insured. The Servicer shall use commercially reasonable efforts to continue to have the Indenture Trustee named as an additional insured on all liability insurance of the purchaser of any Engine for a period of two (2) years following the disposition of such Engine. All insurance provided under this Section 1.03 shall indicate that (x) the proceeds are payable to the Indenture Trustee notwithstanding any action, inaction or breach of representation or warranty by the insured, (y) there shall be no recourse against any Noteholder or the Indenture Trustee for payment of premiums or other amounts with respect to such insurance, and (z) at least thirty (30) days’ prior written notice of cancellation, lapse or material change in coverage be given to the Indenture Trustee by the insurer and that the Indenture Trustee or the Noteholders shall have the right to pay any unpaid premium thereunder. As soon as available (but not later than the related Delivery Date or renewal or replacement dates), the Servicer shall provide WEST and the Indenture Trustee to a certificate of insurance consistent with the requirements of this Section 1.03.

Notwithstanding this section 1.03 or any other provision of this Agreement, the Servicer shall not provide, and shall not be required to provide, under any term of this Agreement or otherwise, any service that may be considered to be the carrying on of “insurance mediation” in Ireland for the purposes of the Irish European Communities (Insurance Mediation) Regulations 2005, as same may be amended or replaced from time to time. For the avoidance of doubt, “insurance mediation” means any activity involved in proposing or undertaking preparatory work for entering into insurance contracts, or of assisting in the administration and performance of insurance contracts that have been entered into (including dealing with claims under insurance contracts).

SECTION 1.04. Administration. The Servicer is authorized to and shall administer each Lease in accordance with its terms and as otherwise specifically addressed herein.

SECTION 1.05. Necessary Filings. On or about the time when WEST or any Subsidiary enters into a Future Lease, the Servicer shall make the necessary filings, if any, and obtain the necessary opinions, if any, required by Section 3.06 of the Security Trust Agreement.

SECTION 1.06. Enforcement. The Servicer is authorized to and shall take reasonable steps to enforce the rights and remedies of the Lessor under each Lease and under any agreements ancillary thereto delivered by WEST to the Servicer (including any guarantees of the obligations of the Lessee) in order to cause the Lessee and any other party (other than the Servicer or WEST) under such Lease to perform their respective obligations owed to the Lessor by such Lessee and such other parties under such Lease and under such ancillary agreements. Following any default by a Lessee under the applicable Lease, the Servicer will provide notice thereof to the Controlling Trustees and will take all steps as it deems reasonably necessary or appropriate to preserve and enforce the rights of the Lessor under the applicable Lease and the Security Trustee, including entering into negotiations with such Lessee with respect to the restructuring of such Lease or declaration of an event of default under the applicable Lease, drawing on or making disbursement or application of any security deposits, Usage Fees or any letters of credit, guarantees or other credit support thereunder, voluntary or involuntary termination of the Lease and repossession of the Engine that is the subject of the Lease, and pursuing such legal action with respect thereto as the Servicer deems reasonably necessary or appropriate. The Servicer shall be authorized to apply any security deposit available under a Lease, if provided therefor in the Lease or permitted by Applicable Law, to the obligations of the Lessee under such Lease and to direct the Indenture Trustee to transfer or liquidate the relevant security deposit for such purpose.

SECTION 1.07. Lease Modifications. (a) The Servicer shall be authorized to make such amendments and modifications to any Lease as it shall deem reasonably necessary or appropriate; provided, however, that such amendment or modification shall require the approval of WEST pursuant to Section 7.06 of the Agreement if the provisions of such amendment or modification, were they to be included in a new Lease to be entered into after the date hereof, would, on their own, cause the entering into of such new Lease to require the approval of WEST pursuant to Section 7.06(a)(ii) of the Agreement. Such amendments or modifications may be made without regard to whether there is a default by the Lessee or other party under or with respect to any such Lease.

(b) The Servicer may waive overdue interest due from any Lessee under any Lease on any default in payment of rent, Usage Fees or other amounts due thereunder.

SECTION 1.08. Options and Other Rights.

(a) The Servicer shall take such action as it shall deem reasonably necessary or appropriate with respect to the exercise by any Lessee of any option or right affecting any Engine Asset according to the terms of the related Engine Document; and

(b) The Servicer is authorized to take such action as it shall deem reasonably necessary or appropriate with the approval of WEST if so required by Section 7.06 or any Subsidiary or, if time is of the essence, without such approval, with respect to the exercise on behalf of WEST or any Subsidiary of any right or option that WEST or any Subsidiary may have with respect to any of the Engine Assets provided that such exercise is in accordance with the terms of the relevant Engine Document.
