Indenture Agreement: Definition & Sample

An indenture agreement is a legally binding document or contract that establishes terms and conditions between two or more parties. Indenture agreements can govern a real estate transaction, a bankruptcy proceeding, or debt agreements.

In the case of a trust indenture, a bond issuer may hire a trustee, and a trust indenture will be required to outline the responsibilities of the trustee and what they will oversee. In the case of a bankruptcy indenture, it may be used to prove a claim of a property. In real estate, an indenture would be the deed between two parties.

The Owner shall not have any responsibility for the distribution of such payment to any Note Holder. Notwithstanding the foregoing or any provision in any Equipment Note to the contrary, the Indenture Trustee will use reasonable efforts to pay or cause to be paid, if so directed in writing by any Note Holder (with a copy to the Owner), all amounts paid by the Owner hereunder and under such holder’s Equipment Note or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant to Article III of this Trust Indenture) by transferring, or causing to be transferred, by wire transfer of immediately available funds in Dollars, prior to 2:00 p.m., New York City time, on the due date of payment, to an account maintained by such holder with a bank located in the continental United States the amount to be distributed to such holder, for credit to the account of such holder maintained at such bank. If the Indenture Trustee shall fail to make any such payment as provided in the immediately foregoing sentence after its receipt of funds at the place and prior to the time specified above, the Indenture Trustee, in its individual capacity and not as trustee, agrees to compensate such holders for loss of use of funds at Debt Rate until such payment is made and the Indenture Trustee shall be entitled to any interest earned on such funds until such payment is made. Any payment made hereunder shall be made without any presentment or surrender of any

Equipment Note, except that, in the case of the final payment in respect of any Equipment Note, such Equipment Note shall be surrendered to the Indenture Trustee for cancellation promptly after such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the Indenture Trustee shall not be required to make, or cause to be made, wire transfers as aforesaid prior to the first Business Day on which it is practicable for the Indenture Trustee to do so in view of the time of day when the funds to be so transferred were received by it if such funds were received after 12:30 p.m., New York time, at the place of payment. Prior to the due presentment for registration of transfer of any Equipment Note, the Owner and the Indenture Trustee shall deem and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable with respect to such Equipment Note and for all other purposes, and none of the Owner or the Indenture Trustee shall be affected by any notice to the contrary. So long as any signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all payments to it shall be made to the account of such Note Holder specified in Schedule 1 thereto and otherwise in the manner provided in or pursuant to the Participation Agreement unless it shall have specified some other account or manner of payment by notice to the Indenture Trustee consistent with this Section 2.03.

(b) The Indenture Trustee, as agent for the Owner, shall exclude and withhold at the appropriate rate from each payment of Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding shall constitute payment in respect of such Equipment Note) any and all United States withholding taxes (including, without limitation, any such withholding taxes imposed under FATCA) applicable thereto as required by Law. The Indenture Trustee agrees to act as such withholding agent and, in connection therewith, whenever any present or future United States taxes or similar charges are required to be withheld with respect to any amounts payable hereunder or in respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate authority in the name of and on behalf of the Note Holders, that it will file any necessary United States withholding tax returns or statements when due, and that as promptly as possible after the payment thereof it will deliver to each Note Holder (with a copy to the Owner) appropriate receipts showing the payment thereof, together with such additional documentary evidence as any such Note Holder may reasonably request from time to time.

If a Note Holder which is a Non-U.S. Person has furnished to the Indenture Trustee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8BEN, W-8EXP or W-8IMY (or such successor form or forms as may be required by the United States Treasury Department) during the calendar year in which the payment hereunder or under the Equipment Note(s) held by such holder is made (but prior to the making of such payment), or in any of the three preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of such form prior to the date of such payment (and the Indenture Trustee has no reason to believe that any information set forth in such form is inaccurate), the Indenture Trustee shall withhold only the amount, if any, required by Law (after taking into account any applicable exemptions properly claimed by the Note Holder) to be withheld from payments hereunder or under the Equipment Notes held by such holder in respect of United States federal income tax, including any amounts required to be withheld under FATCA. If a Note Holder (x) which is a Non-U.S. Person has furnished to the Indenture Trustee

a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-8ECI in duplicate (or such successor certificate, form or forms as may be required by the United States Treasury Department as necessary in order to properly avoid withholding of United States federal income tax) during the calendar year in which the payment hereunder or under the Equipment Note(s) held by such holder is made (but prior to the making of such payment) or in any of the three preceding calendar years, and has not notified the Indenture Trustee of the withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the Indenture Trustee has no reason to believe that any information set forth in such form is inaccurate) or (y) which is a U.S. Person has furnished to the Indenture Trustee a properly completed, accurate and currently effective U.S. Internal Revenue Service Form W-9, if applicable, prior to a payment hereunder or under the Equipment Notes held by such holder, no amount shall be withheld from payments in respect of United States federal income tax. If any Note Holder has notified the Indenture Trustee that any of the foregoing forms or certificates is withdrawn or inaccurate, or if such holder has not filed a form claiming an exemption from United States withholding tax or if an applicable income tax convention, the Code or the regulations thereunder or the administrative interpretation of any of the foregoing is at any time after the date hereof amended to require such withholding of United States federal income taxes from payments under the Equipment Notes held by such holder, the Indenture Trustee agrees to withhold from each payment due to the relevant Note Holder withholding taxes at the appropriate rate under Law and will, on a timely basis as more fully provided above, deposit such amounts with an authorized depository and make such returns, statements, receipts and other documentary evidence in connection therewith as required by Law.

SECTION 2.04. Application of Payments

In the case of each Equipment Note, each payment of Original Amount, Make-Whole Amount, if any, and interest due thereon shall be applied:

Second: to the payment of accrued interest on such Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, and to the extent permitted by Law, any overdue interest and any other overdue amounts thereunder) to the date of such payment;

Third: to the payment of the Original Amount of such Equipment Note (or a portion thereof) then due thereunder; and

Fourth: the balance, if any, remaining thereafter, to the payment of the Original Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not be subject to redemption except as provided in Sections 2.09, 2.10 and 2.11 hereof).

The amounts paid pursuant to clause “Fourth” above shall be applied to the installments of Original Amount of such Equipment Note in the inverse order of their maturity.

SECTION 2.05. Termination of Interest in Collateral

No Note Holder nor any other Indenture Indemnitee shall, as such, have any further interest in, or other right with respect to, the Collateral when and if the Original Amount of, Make-Whole Amount, if any, and interest on and other amounts due under all Equipment Notes held by such Note Holder and all other sums then due and payable to such Note Holder, such Indenture Indemnitee or the Indenture Trustee hereunder (including, without limitation, under the third paragraph of Section 2.02 hereof) and under the other Operative Agreements by the Owner and all Related Secured Obligations (collectively, the “Secured Obligations”) shall have been paid in full.

SECTION 2.06. Registration Transfer and Exchange of Equipment Notes

The Indenture Trustee shall keep a register (the “Equipment Note Register”) in which the Indenture Trustee shall provide for the registration of Equipment Notes and the registration of transfers of Equipment Notes. No such transfer shall be given effect unless and until registration hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust Office of the Indenture Trustee. The Indenture Trustee is hereby appointed “Equipment Note Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as herein provided. A holder of any Equipment Note intending to exchange such Equipment Note shall surrender such Equipment Note to the Indenture Trustee at the Corporate Trust Office, together with a written request from the registered holder thereof for the issuance of a new Equipment Note, specifying, in the case of a surrender for transfer, the name and address of the new holder or holders. Upon surrender for registration of transfer of any Equipment Note, the Owner shall execute, and the Indenture Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Equipment Notes of a like aggregate Original Amount and of the same Series. At the option of the Note Holder, Equipment Notes may be exchanged for other Equipment Notes of any authorized denominations of a like aggregate Original Amount, upon surrender of the Equipment Notes to be exchanged to the Indenture Trustee at the Corporate Trust Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner shall execute, and the Indenture Trustee shall authenticate and deliver, the Equipment Notes which the Note Holder making the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer or exchange of Equipment Notes (whether under this Section 2.06 or under Section 2.07 hereof or otherwise under this Trust Indenture) shall be the valid obligations of the Owner evidencing the same respective obligations, and entitled to the same security and benefits under this Trust Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange. Every Equipment Note presented or surrendered for registration of transfer, shall (if so required by the Indenture Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Indenture Trustee duly executed by the Note Holder or such holder’s attorney duly authorized in writing, and the Indenture Trustee shall require evidence satisfactory to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of any applicable state. The Indenture Trustee shall make a notation on each new Equipment Note of the amount of all payments of Original Amount previously made on the old Equipment Note or Equipment Notes with respect to which such new Equipment Note is issued and the date to which interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be deemed to have been paid on such new Equipment Note to the date on which interest shall have

been paid on such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note, as provided above, shall be deemed to have been made thereon. The Owner shall not be required to exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the due date of any payment on such Equipment Note. The Owner shall in all cases deem the Person in whose name any Equipment Note shall have been issued and registered as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the Owner with respect to such Equipment Note and for all purposes until a notice stating otherwise is received from the Indenture Trustee and such change is reflected on the Equipment Note Register. The Indenture Trustee will promptly notify the Owner of each registration of a transfer of an Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note, (i) agrees to the provisions of this Trust Indenture and the Participation Agreement applicable to Note Holders, including Sections 6.3, 6.4 and 9.1 thereof, and shall be deemed to have covenanted to the parties to the Participation Agreement as to the matters covenanted by the original Note Holder in the Participation Agreement and (ii) agrees to the restrictions set forth in Sections 4.1(a)(i) and 4.1(a)(iii) of the Intercreditor Agreement, and shall be deemed to have covenanted to the parties to the Intercreditor Agreement not to give any direction, or otherwise authorize, the Indenture Trustee to take any action that would violate Sections 4.1(a)(i) or 4.1(a)(iii) of the Intercreditor Agreement. Subject to compliance by the Note Holder and its transferee (if any) of the requirements set forth in this Section 2.06, the Indenture Trustee and the Owner shall use all reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days of the date an Equipment Note is surrendered for transfer or exchange.

SECTION 2.07. Mutilated, Destroyed, Lost or Stolen Equipment Notes

If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner shall, upon the written request of the holder of such Equipment Note, execute and the Indenture Trustee shall authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original Amount dated the same date and captioned as issued in connection with the Aircraft. If the Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the Indenture Trustee and a photocopy thereof shall be furnished to the Owner. If the Equipment Note being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish to the Owner and the Indenture Trustee such security or indemnity as may be required by them to save the Owner and the Indenture Trustee harmless and evidence satisfactory to the Owner and the Indenture Trustee of the destruction, loss or theft of such Equipment Note and of the ownership thereof. If a “qualified institutional buyer” of the type referred to in paragraph (a)(1)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act (a “QIB”) is the holder of any such destroyed, lost or stolen Equipment Note, then the written indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to and in form reasonably satisfactory the Owner shall be accepted as satisfactory indemnity and security and no further indemnity or security shall be required as a condition to the execution and delivery of such new Equipment Note. Subject to compliance by the Note Holder with the requirements set forth in this Section 2.07, the Indenture Trustee and the Owner shall use all reasonable efforts to issue new Equipment Notes within 10 Business Days of the date of the written request therefor from the Note Holder.

SECTION 2.08. Payment of Expenses on Transfer; Cancellation

(a) No service charge shall be made to a Note Holder for any registration of transfer or exchange of Equipment Notes, but the Indenture Trustee, as Equipment Note Registrar, may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Equipment Notes.

(b) The Indenture Trustee shall cancel all Equipment Notes surrendered for replacement, redemption, transfer, exchange, payment or cancellation and shall destroy the canceled Equipment Notes.

Any Wet Lease or similar arrangement under which the Owner maintains operational control of the Aircraft shall not constitute a deliver, transfer or relinquishment of possession of the Aircraft for purposes of this Section.

The Indenture Trustee hereby agrees, and each Note Holder and Related Note Holder by acceptance of an Equipment Note and a Related Equipment Note, respectively, agrees, for the benefit of each lessor, conditional seller, indenture trustee or secured party of any engine leased to, or purchased by, the Owner or any Permitted Lessee subject to a lease, conditional sale, trust indenture or other security agreement that the Indenture Trustee, each Note Holder and Related Note Holder and their respective successors and assigns will not acquire or claim, as against such lessor, conditional seller, indenture trustee or secured party, any right, title or interest in any engine as the result of such engine being installed on the Airframe at any time

while such engine is subject to such lease, conditional sale, trust indenture or other security agreement and owned by such lessor or conditional seller or subject to a trust indenture or security interest in favor of such indenture trustee or secured party.

(c) Operation and Use . So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not operate, use or locate the Aircraft, Airframe or any Engine, or allow the Aircraft, Airframe or any Engine to be operated, used or located, (i) in any area excluded from coverage by any insurance required by the terms of Section 4.06, except in the case of a requisition by the U.S. Government where the Owner obtains indemnity in lieu of such insurance from the U.S. Government, or insurance from the U.S. Government, against substantially the same risks and for at least the amounts of the insurance required by Section 4.06 covering such area, or (ii) in any recognized area of hostilities unless covered in accordance with Section 4.06 by war risk insurance, or in either case unless the Aircraft, the Airframe or any Engine is only temporarily operated, used or located in such area as a result of an emergency, equipment malfunction, navigational error, hijacking, weather condition, medical emergency or other circumstances beyond the reasonable control of the Owner (or any Permitted Lessee), so long as the Owner (or any Permitted Lessee) diligently and in good faith proceeds to remove the Aircraft from such area. The Owner shall also have the right to operate the Aircraft without having on board the original registration certificate or airworthiness certificate in the event that either or both such certificates disappear from the Aircraft, but only to the extent permitted by Exemption No. 5318 of the FAA Regulations or other similar exemption. So long as the Aircraft, the Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall not permit such Aircraft, Airframe or any Engine, as the case may be, to be used, operated, maintained, serviced, repaired or overhauled (x) in violation of any Law of any Government Entity having jurisdiction over the Aircraft that is binding on or applicable to such Aircraft, Airframe or Engine or (y) in violation of any airworthiness certificate, license or registration of any Government Entity relating to the Aircraft, the Airframe or any Engine, except (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by the Owner or Permitted Lessee, as the case may be, upon discovery thereof, or (ii) to the extent the validity or application of any such Law or requirement relating to any such certificate, license or registration is being contested in good faith by the Owner or Permitted Lessee in any reasonable manner which does not involve any material risk of the sale, forfeiture or loss of the Aircraft, Airframe or any Engine, any material risk of criminal liability or material civil penalty against the Indenture Trustee or impair the Indenture Trustee’s security interest or International Interest in the Aircraft, Airframe or any Engine. Owner shall not be in default under or required to take any action set forth in the preceding sentence if it is not possible for Owner to comply with the laws of a jurisdiction other than the United States (or other jurisdiction in which the Aircraft is registered) because of a conflict with the Laws of the United States (or other jurisdiction in which the Aircraft is registered).

(d) Maintenance and Repair . So long as the Aircraft, Airframe or any Engine is subject to the Lien of this Trust Indenture, the Owner shall cause the Aircraft, Airframe and each Engine to be maintained, serviced, repaired and overhauled in accordance with (i) maintenance standards required by or substantially equivalent to those required by the Owner’s FAA approved maintenance program or while registered in another jurisdiction, under the applicable maintenance standards required by the Aviation Authority in such jurisdiction

( provided , that in any case, if operated under the maintenance program of an Aviation Authority other the FAA, the Aircraft, Airframe and each Engine shall be maintained according to standards substantially equivalent to those required by the Aviation Authority of any of Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland or the United Kingdom) so as to (A) keep the Aircraft, the Airframe and each Engine in as good operating condition as on the Closing Date, ordinary wear and tear excepted, (B) keep the Aircraft in such operating condition as may be necessary to enable the applicable airworthiness certification of such Aircraft to be maintained under the regulations of the FAA or other Aviation Authority then having jurisdiction over the operation of the Aircraft, except (w) during temporary periods of storage in accordance with applicable regulations, (x) maintenance, testing and modification permitted hereunder, (y) during periods when the FAA or such other Aviation Authority has revoked or suspended the airworthiness certificates for Similar Aircraft or (z) with respect to minor or nonrecurring violations with respect to which corrective measures are taken upon discovery thereof and except to the extent the Owner or Permitted Lessee is promptly contesting in good faith the validity or application of any such Law or requirement relating to any such certificate, license or registration in any reasonable manner which does not create a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any Engine or the interest of the Indenture Trustee therein or any material risk of criminal liability or material civil penalty against the Indenture Trustee; and (ii) except during periods when a Permitted Lease is in effect, the same standards as the Owner uses with respect to similar aircraft of similar size in its fleet operated by the Owner in similar circumstances and, during any period in which a Permitted Lease is in effect, the same standards used by the Permitted Lessee with respect to similar aircraft of similar size in its fleet and operated by the Permitted Lessee in similar circumstances (it being understood that this clause (ii) shall not limit the Owner’s obligations under the preceding clause (i)). The Owner further agrees that the Aircraft, Airframe and Engines will be maintained, used, serviced, repaired, overhauled or inspected in compliance with each applicable airworthiness certificate, license and registration relating to the Aircraft, Airframe or any Engine issued by the FAA (or other applicable Aviation Authority). The Owner shall maintain or cause to be maintained the Aircraft Documents in the English language.

(e) Registration . The Owner on or prior to the date of the Closing shall cause the Aircraft to be duly registered in its name under the Act and except as otherwise permitted by this Section 4.02(e) at all times thereafter shall cause the Aircraft to remain so registered. So long as no Special Default or Event of Default shall have occurred and be continuing, the Owner may, by written notice to the Indenture Trustee, request to change the country of registration of the Aircraft. Any such change in registration shall be effected only in compliance with, and subject to all of the conditions set forth in, Section 6.4.5 of the Participation Agreement. Unless the Trust Indenture has been discharged, the Owner shall also cause the Trust Indenture to be duly recorded and at all times maintained of record as a first-priority perfected mortgage (subject to Permitted Liens) on the Aircraft, the Airframe and each of the Engines (except to the extent such perfection or priority cannot be maintained solely as a result of the failure by the Indenture Trustee to execute and deliver any necessary documents). Unless the Lien of this Indenture has been discharged, the Owner shall cause the International Interest granted under this Indenture in favor of the Indenture Trustee in each Airframe and Engine to be registered on the International Registry as an International Interest on such Airframe and Engine, subject to the Indenture Trustee providing its consent to the International

Registry with respect thereto[, and shall cause the sale to the Owner of the Airframe and each Engine at the Closing to be registered on the International Registry] 9 .

(f) Markings . If permitted by applicable Law, on or reasonably promptly after the Closing Date, the Owner will cause to be affixed to, and maintained in, the cockpit of the Airframe and on each Engine, in each case, in a clearly visible location, a placard of a reasonable size and shape bearing the legend: “Subject to a security interest in favor of Wilmington Trust Company, not in its individual capacity but solely as Indenture Trustee.” Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframe or Engines. If any such placard is damaged or becomes illegible, the Owner shall promptly replace it with a placard complying with the requirements of this Section.

SECTION 4.03. Inspection

(a) At all reasonable times upon at least 15 Business Days prior written notice to Owner, so long as the Aircraft is subject to the Lien of this Trust Indenture, the Indenture Trustee and its authorized representatives (the “Inspecting Parties”) may (not more than once every twelve (12) months unless an Event of Default has occurred and is continuing then such inspection right shall not be so limited) inspect the Aircraft, Airframe and Engines (including without limitation, the Aircraft Documents) and any such Inspecting Party may make copies of such Aircraft Documents not reasonably deemed confidential by the Owner or such Permitted Lessee.

(b) Any inspection of the Aircraft hereunder shall be limited to a visual, walk-around inspection and shall not include the opening of any panels, bays or the like or other components of the Aircraft, and no such inspection shall interfere with the Owner’s or any Permitted Lessee’s maintenance and operation of the Aircraft, Airframe and Engines. Any inspection shall be subject to the Owner’s safety and security rules applicable to the location of the Aircraft.

(c) With respect to such rights of inspection, the Indenture Trustee shall not have any duty or liability to make, or any duty or liability by reason of not making, any such visit, inspection or survey.

(d) Each Inspecting Party shall bear its own expenses in connection with any such inspection (including the cost of any copies made in accordance with Section 4.03(a)).

SECTION 4.04. Replacement and Pooling of Parts, Alterations, Modifications and Additions; Substitution of Engines

(a) Replacement of Parts . Except as otherwise provided herein, so long as the Airframe or Engine is subject to the Lien of this Trust Indenture, the Owner, at its own cost and expense, will, or will cause a Permitted Lessee to, at its own cost and expense, promptly replace (or cause to be replaced) all Parts which may from time to time be incorporated

or installed in or attached to the Aircraft, Airframe or any Engine and which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use for any reason whatsoever, except as otherwise provided in paragraph (d) of this Section 4.04 or if the Airframe or Engine to which a Part relates has suffered an Event of Loss. In addition, the Owner may, at its own cost and expense, or may permit a Permitted Lessee at its own cost and expense to, remove (or cause to be removed) in the ordinary course of maintenance, service, repair, overhaul or testing any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use; provided , however , that the Owner, except as otherwise provided herein, at its own cost and expense, will, or will cause a Permitted Lessee at its own cost and expense to, replace such Parts as promptly as practicable. All replacement parts shall be free and clear of all Liens, except for Permitted Liens and pooling arrangements to the extent permitted by Section 4.04(c) below (and except in the case of replacement property temporarily installed on an emergency basis) and shall be in good operating condition and have a value and utility not less than the value and utility of the Parts replaced (assuming such replaced Parts were in the condition required hereunder).

(b) Parts . Except as otherwise provided herein, any Part at any time removed from the Airframe or any Engine shall remain subject to the Lien of this Trust Indenture, no matter where located, until such time as such Part shall be replaced by a part that has been incorporated or installed in or attached to such Airframe or any Engine and that meets the requirements for replacement parts specified above. Immediately upon any replacement part becoming incorporated or installed in or attached to such Airframe or any Engine as provided in Section 4.04(a), without further act, (i) the replaced Part shall thereupon be free and clear of all rights of the Indenture Trustee and shall no longer be deemed a Part hereunder, and (ii) such replacement part shall become a Part subject to this Trust Indenture and be deemed part of such Airframe or any Engine, as the case may be, for all purposes hereof to the same extent as the Parts originally incorporated or installed in or attached to such Airframe or any Engine. Upon request of Owner, the Indenture Trustee shall, at Owner’s expense, execute and deliver to Owner such documents as may be reasonably required to evidence the release of any replaced Part from the Lien of the Indenture.

(c) Pooling of Parts . Any Part removed from the Aircraft, Airframe or an Engine may be subjected by the Owner or a Permitted Lessee to a normal pooling arrangement customary in the airline industry and entered into in the ordinary course of business of the Owner or Permitted Lessee, provided that the part replacing such removed Part shall be incorporated or installed in or attached to such Airframe or any Engine in accordance with Sections 4.04(a) and 4.04(b) as promptly as practicable after the removal of such removed Part. In addition, any replacement part when incorporated or installed in or attached to the Airframe or any Engine may be owned by any third party, subject to a normal pooling arrangement, so long as the Owner or a Permitted Lessee, at its own cost and expense, as promptly thereafter as reasonably possible, either (i) causes such replacement part to become subject to the Lien of this Trust Indenture, free and clear of all Liens except Permitted Liens, at which time such replacement part shall become a Part or (ii) replaces (or causes to be replaced) such replacement part by incorporating or installing in or attaching to the Aircraft, Airframe or any Engine a further replacement part owned by the Owner free and clear of all Liens except Permitted Liens

and which shall become subject to the Lien of this Trust Indenture in accordance with Section 4.04(b).

(d) Alterations, Modifications and Additions . The Owner shall, or shall cause a Permitted Lessee to, make (or cause to be made) alterations and modifications in and additions to the Aircraft, Airframe and each Engine as may be required to be made from time to time to meet the applicable standards of the FAA or other Aviation Authority having jurisdiction over the operation of the Aircraft, to the extent made mandatory in respect of the Aircraft (a “Mandatory Modification”); except for (i) immaterial and non-recurring violations with respect to which corrective measures are being taken promptly by Owner or a Permitted Lessee and (ii) any law, rule, regulation or order the validity or application of which is being contested in good faith by the Owner or any Permitted Lessee in any reasonable manner which does not materially adversely affect the Indenture Trustee’s interest in the Aircraft, does not impair the Indenture Trustee’s security interest or International Interest in the Aircraft and does not involve any material risk of sale, forfeiture or loss of the Aircraft or the interest of the Indenture Trustee therein or any material risk of material civil penalty or any material risk of criminal liability being imposed on the Indenture Trustee or the holder of any Equipment Note. In addition, the Owner, at its own expense, may, or may permit a Permitted Lessee at its own cost and expense to, from time to time make or cause to be made such alterations and modifications in and additions to the Airframe or any Engine (each an “Optional Modification”) as the Owner or such Permitted Lessee may deem desirable in the proper conduct of its business including, without limitation, removal of Parts which the Owner deems are obsolete or no longer suitable or appropriate for use in the Aircraft, Airframe or such Engine; provided , however , that no such Optional Modification shall (i) materially diminish the fair market value, utility, or useful life of the Aircraft or any Engine below its fair market value, utility or useful life immediately prior to such Optional Modification (assuming the Aircraft or such Engine was in the condition required by this Trust Indenture immediately prior to such Optional Modification) or (ii) cause the Aircraft to cease to have the applicable standard certificate of airworthiness except that such certificate of airworthiness temporarily may be replaced by an experimental certificate during the process of implementing and testing such Optional Modification and securing related FAA re-certification of the Aircraft. For the avoidance of doubt, Owner may make alterations in the passenger configuration of the Aircraft and such alterations shall not constitute an Optional Modification. All Parts incorporated or installed in or attached to any Airframe or any Engine as the result of any alteration, modification or addition effected by the Owner shall be free and clear of any Liens except Permitted Liens and become subject to the Lien of this Trust Indenture; provided that the Owner or any Permitted Lessee may, at any time so long as the Airframe or any Engine is subject to the Lien of this Trust Indenture, remove any such Part (such Part being referred to herein as a “ Removable Part ”) from such Airframe or an Engine if (i) such Part is in addition to, and not in replacement of or in substitution for, any Part originally incorporated or installed in or attached to such Airframe or any Engine at the time of delivery thereof hereunder or any Part in replacement of, or in substitution for, any such original Part, (ii) such Part is not required to be incorporated or installed in or attached or added to such Airframe or any Engine pursuant to the terms of Section 4.02(d) or the first sentence of this Section 4.04(d) and (iii) such Part can be removed from such Airframe or any Engine without materially diminishing the fair market value, utility or remaining useful life which such Airframe or any Engine would have had at the time of removal had such removal not been effected by the Owner, assuming the Aircraft was otherwise maintained in the condition required by this Trust

Indenture and such Removable Part had not been incorporated or installed in or attached to the Aircraft, Airframe or such Engine. Upon the removal by the Owner of any such Part as above provided in this Section 4.04(d), title thereto shall, without further act, be free and clear of all rights of the Indenture Trustee and such Part shall no longer be deemed a Part hereunder. Removable Parts may be leased from or financed by third parties other than the Indenture Trustee. Notwithstanding any other provision of this Indenture, Owner may, at any time, install or permit to be installed in the Aircraft Passenger Convenience Equipment owned by Owner or any Permitted Lessee or by third parties and leased or otherwise furnished to Owner in the ordinary course of business (including pursuant to a conditional sale contract, a licence or otherwise), and Owner may remove (and not replace) or permit to be removed (and not replaced) the same, and Indenture Trustee shall not acquire a Lien thereon by virtue of such installation or otherwise, and the rights of the owners therein shall not constitute a default under this Trust Indenture, it being acknowledged and agreed, however, that in no event shall the installation of any such Passenger Convenience Equipment impair or otherwise affect the rights and remedies of the Indenture Trustee hereunder and under applicable law.

(e) Substitution of Engines . Upon the occurrence of an Event of Loss with respect to an Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, the Owner shall promptly (and in any event within fifteen (15) days after such occurrence) give the Indenture Trustee written notice of such Event of Loss. The Owner shall have the right at its option at any time, on at least five (5) Business Days’ prior notice to the Indenture Trustee, to substitute, and if an Event of Loss shall have occurred with respect to an Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred, shall within one hundred and twenty (120) days of the occurrence of such Event of Loss substitute, a Replacement Engine for any Engine. In such event, immediately upon the effectiveness of such substitution and without further act, (i) the replaced Engine shall thereupon be free and clear of all rights of the Indenture Trustee and the Lien of this Trust Indenture and shall no longer be deemed an Engine hereunder and (ii) such Replacement Engine shall become subject to this Trust Indenture and be deemed part of the Aircraft for all purposes hereof to the same extent as the replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer that is the same model as the Engine to be replaced thereby, or an improved model, and that is suitable for installation and use on the Airframe, and that has a value, utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine to be replaced thereby (assuming that such Engine had been maintained in accordance with this Trust Indenture). The Owner’s right to make a replacement hereunder shall be subject to the fulfillment (which may be simultaneous with such replacement) of the following conditions precedent at the Owner’s sole cost and expense, and the Indenture Trustee agrees to cooperate with the Owner to the extent necessary to enable it to timely satisfy such conditions:

(i) an executed counterpart of each of the following documents shall be delivered to the Indenture Trustee:

(A) a Trust Indenture Supplement covering the Replacement Engine, which shall have been duly filed for recordation pursuant to the Act or such other applicable law of the jurisdiction other than the United States in which the

Aircraft of which such Engine is a part is registered in accordance with Section 4.02(e), as the case may be;

(B) a full warranty bill of sale (as to title), covering the Replacement Engine, executed by the former owner thereof in favor of the Owner (or, at the Owner’s option, other evidence of the Owner’s ownership of such Replacement Engine, reasonably satisfactory to the Indenture Trustee); and

(C) UCC financing statements covering the security interests created by this Trust Indenture (or any similar statements or other documents required to be filed or delivered pursuant to the laws of the jurisdiction in which such Aircraft may be registered) as are deemed necessary or desirable by counsel for the Indenture Trustee to protect the security interests of the Indenture Trustee in the Replacement Engine;

(ii) the Owner shall cause to be delivered to the Indenture Trustee an opinion of counsel to the effect that the Lien of this Trust Indenture continues to be in full force and effect with respect to the Replacement Engine and such evidence of compliance with the insurance provisions of Section 4.06 with respect to such Replacement Engine as the Indenture Trustee shall reasonably request;

(iii) promptly after the filing of the Trust Indenture Supplement, the Owner shall have caused to be furnished to the Indenture Trustee an opinion of the Owner’s aviation law counsel reasonably satisfactory to the Indenture Trustee addressed to the Indenture Trustee as to the due filing for recordation of the Trust Indenture Supplement with respect to such Replacement Engine under the Act or such other applicable law of the jurisdiction other than the United States in which the Aircraft is registered in accordance with Section 4.02(e), as the case may be, and the registration (which the Owner shall have caused to be effected) with the International Registry of the sale to the Owner of such Replacement Engine (if occurring after February 28, 2006) and the International Interest granted under such Trust Indenture Supplement with respect to such Replacement Engine; and

(iv) the Owner shall have furnished to the Indenture Trustee a certificate of a qualified aircraft engineer (who may be an employee of the Owner) or an independent appraiser certifying that such Replacement Engine has a value and utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine so replaced (assuming that such Engine had been maintained in accordance with this Trust Indenture).

Upon satisfaction of all conditions to such substitution, (x) the Indenture Trustee shall execute and deliver to the Owner such documents and instruments, prepared at the Owner’s expense, as the Owner shall reasonably request to evidence the release of such replaced Engine from the Lien of this Trust Indenture, (y) the Indenture Trustee shall assign to the Owner all claims it may have against any other Person relating to any Event of Loss giving rise to such substitution and (z) the Owner shall receive all insurance proceeds (other than those reserved to others under Section 4.06(b)) and proceeds in respect of any Event of Loss giving rise to such replacement to

the extent not previously applied to the purchase price of the Replacement Engine as provided in Section 4.05(d).
