                  -----------

(a)      General Indemnity.  Subject to the next following paragraph but without limiting any other rights that any Indemnitee may
         -----------------
     have under the other Operative Documents or applicable law, the Borrower hereby agrees to indemnify each Indemnitee against, and
     agrees to protect, save and keep harmless each of them from any and all Expenses imposed on, incurred by or asserted against any
     Indemnitee arising out of or resulting from (i) the operation, possession, use, maintenance, overhaul, testing, registration,

     any engine used in connection with any Airframe or any part of any of the foregoing by the Borrower, any lessee or any other
     Person whatsoever, whether or not such operation, possession, use, maintenance, overhaul, testing, registration, reregistration,
     delivery, non-delivery, lease, nonuse, modification, alteration, or sale is in compliance with the terms of the Mortgage,
     including, without limitation, claims for death, personal injury or property damage or other loss or harm to any person
     whatsoever and claims relating to any laws, rules or regulations pertaining to such operation, possession, use, maintenance,
     overhaul, testing, registration, reregistration, delivery, non-delivery, lease, non-use, modification, alteration, sale or return
     including environmental control, noise and pollution laws, rules or regulations; (ii) the manufacture, design, purchase,
     acceptance, rejection, delivery, or condition of any Aircraft, Airframe or Engine, any engine used in connection with any
     Airframe, or any part of any of the foregoing including, without limitation, latent and other defects, whether or not
     discoverable, or trademark or copyright infringement; (iii) any breach of or failure to perform or observe, or any other
     noncompliance with, any covenant or agreement to be performed, or other obligation of the Borrower under any of the Operative
     Documents, or the falsity of any representation or warranty of the Borrower in any of the Operative Documents; and (iv) any Event
     of Default hereunder or the enforcement against the Borrower of any of the terms hereof (including, without limitation, Section
     12 hereof).

                  The foregoing indemnity shall not extend to any Expense of any Indemnitee to the extent attributable to one or more
of the following:  (1) acts or omissions involving the willful misconduct or gross negligence of such Indemnitee or any Person acting
on behalf of such Indemnitee (other than gross negligence imputed to such Indemnitee solely by reason of its interest in an Aircraft,
as finally determined by a court of competent jurisdiction); (2) any Tax, or increase in tax liability under any tax law (such matter
being the subject to the indemnity in Sections 8(b) and (c) hereof); (3) a failure on the part of the Administrative Agent to
distribute in accordance with the Operative Documents any amounts received and distributable by it thereunder; (4) any breach of
undertaking or any misrepresentation contained herein or in any other Operative Document to which such Indemnitee is a party or any
agreement relating hereto or thereto by such Indemnitee and in each case not attributable directly to any breach of undertaking, any
misrepresentation or any noncompliance with any of the terms hereof or of any other Operative Document or any agreement relating
hereto or thereto by Borrower; (5) attributable to a Lender Lien; or (6) any Expenses as a result of a violation of the Securities
Act (as defined below) relating to or arising out of the offer, issuance, sale or delivery by any Indemnitee (or any person who

                                                                                            --------------
Commercial Paper or any security based upon the credit of the Borrower.

                  The Borrower further agrees that any payment or indemnity pursuant to this Section 8(a) in respect of any "Expense"
shall be in an amount which, after deduction of all Taxes required to be paid by such recipient with respect to such payment or
indemnity under the laws of any federal, state or local government or taxing authority in the United States, or under the laws of any
taxing authority or governmental subdivision of a foreign country, or any territory or possession of the United States or any
international authority, shall be equal to the excess, if any, of (A) the amount of such Expense over (B) the net reduction in Taxes
required to be paid by such recipient resulting from the accrual or payment of such Expense.

                  If a claim is made against an Indemnitee involving one or more Expenses and such Indemnitee has notice thereof, such
Indemnitee (or its agent) shall promptly after receiving such notice give notice of such claim to the Borrower; provided that the
failure to provide such notice shall not release the Borrower from any of its obligations to indemnify hereunder except to the extent
that the Borrower is prejudiced as a result of the failure to give such notice in a timely fashion, and no payment by the Borrower to
an Indemnitee pursuant to this Section 8(a) shall be deemed to constitute a waiver or release of any right or remedy which the
Borrower may have against such Indemnitee for any actual damages as a result of the failure by such Indemnitee to give the Borrower
such notice.  The Borrower shall be entitled, at its sole cost and expense, acting through a single counsel reasonably acceptable to
the respective Indemnitee, so long as the Borrower has acknowledged in writing its responsibility for such Expense hereunder (unless
such Expense is covered by the second paragraph of this Section 8(a), except that such acknowledgment does not apply if the decision
of a court or arbitrator provides that the Borrower is not liable hereunder), (A) in any judicial or administrative proceeding that
involves solely a claim for one or more Expenses, to assume responsibility for and control thereof, (B) in any judicial or
administrative proceeding involving a claim for one or more Expenses and other claims related or unrelated to the transactions
contemplated by the Operative Documents, to assume responsibility for and control of such claim for Expenses to the extent that the
same may be and is severed from such other claims (and such Indemnitee shall use its reasonable efforts to obtain such severance),
and (C) in any other case, to be consulted by such Indemnitee with respect to judicial proceedings subject to the control of such
Indemnitee and to be allowed, at the Borrower's sole expense, to participate therein.  The Indemnitee may participate at its own
expense and with its own counsel in any judicial proceeding controlled by the Borrower pursuant to the preceding provisions.
Notwithstanding any of the foregoing, the Borrower shall not be entitled to assume responsibility for and control of any such
judicial or administrative proceedings if any Event of Default shall have occurred and be continuing, if such proceedings will
involve a material risk of the sale, forfeiture or loss of an Aircraft unless the Borrower shall have posted a bond or other security
reasonably satisfactory to the relevant Indemnitee with respect to such risk or if such proceedings could entail any risk of criminal
liability being imposed on such Indemnitee.

                  The Indemnitee shall supply the Borrower with such information reasonably requested by the Borrower as is necessary
or advisable for the Borrower to control or participate in any proceeding to the extent permitted by this Section 8(a).  Such
Indemnitee shall not enter into a settlement or other compromise with respect to any Expense without the prior written consent of the
Borrower, which consent shall not be unreasonably withheld or delayed, unless such Indemnitee waives its right to be indemnified with
respect to such Expense under this Section 8(a).  In the case of any Expense indemnified by Borrower hereunder which is covered by a
policy of insurance maintained by Borrower, each Indemnitee agrees, at Borrower's expense, to cooperate reasonably with the insurers
in the exercise of their rights to investigate, defend or compromise such loss or liability as may be reasonably required to retain
the benefits of such insurance with respect to such loss or liability.

                  To the extent of any payment of any Expense pursuant to this Section 8(a), the Borrower, without any further action,
shall be subrogated to any claims the Indemnitee may have relating thereto.  The Indemnitee agrees to give such further assurances or
agreements and to cooperate with the Borrower to permit the Borrower to pursue such claims, if any, to the extent reasonably
requested by the Borrower.

                  In the event that the Borrower shall have paid an amount to an Indemnitee pursuant to this Section 8(a), and such
Indemnitee subsequently shall be reimbursed in respect of such indemnified amount from any other Person, such Indemnitee shall
promptly pay the Borrower the amount of such reimbursement, including interest received attributable thereto, provided that no
Special Default or Event of Default has occurred and is continuing.

(b)      General Tax Indemnity.
         ---------------------

(i)      Subject to the exclusions described in Section 8(b)(ii) below, any and all payments by the Borrower to the Administrative
     Agent, the Collateral Agent or the Lender (and, to the extent the Lender is a CP Conduit, such Lender's Program Support
     Providers) (each, a "Tax Indemnitee") under this Agreement or any of the other Operative Documents shall be made free and clear
     of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all
     liabilities with respect thereto, excluding taxes measured by or based on net or taxable income (all such non-excluded taxes,
     levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes").  If any Taxes shall
                                                                                                          -----
     be required by law to be deducted from or in respect of any sum payable under this Agreement to any Tax Indemnitee, then (i) the
     sum payable by the Borrower shall be increased as may be necessary so that after making all required deductions in respect of
     such Taxes (including deductions applicable to additional sums payable under this Section) such Tax Indemnitee (as the case may
     be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make
     such deductions, and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority
     in accordance with applicable law.  The Borrower shall not, however, be required to pay amounts, if any, pursuant to clause (i)
     of the preceding sentence to any Tax Indemnitee organized under the laws of a jurisdiction outside of the United States of
     America unless such Tax Indemnitee provides or has provided to the Borrower a completed Internal Revenue Service Form 4224 (or
     new Form W-8ECI) or Form 1001 (or new Form W-8BEN), or any successor form, and a completed Internal Revenue Service Form W-8 (or
     new Form W-8BEN) or W-9, or any successor form, and any other applicable form, certificate or document prescribed by the Internal
     Revenue Service of the United States certifying as to such Tax Indemnitee's entitled to an exemption from, or reduction of,
     United States withholding tax on payments to be made hereunder and any new or other forms or certificates prescribed by the
     Internal Revenue Service of the United States in the event that a lapse in time or change in circumstance renders a previous
     certification obsolete or inaccurate in any material respect.

                  The Borrower agrees to pay any present or future stamp, recording or documentary taxes or similar levies that arise
from any payment made under this Agreement or under any other Operative Document or from the execution, delivery or registration of,
or otherwise with respect to, this Agreement or any other Operative Document (hereinafter referred to as "Other Taxes").
                                                                                                          -----------

                  The Borrower will indemnify each Tax Indemnitee for the full amount of Taxes or Other Taxes (including any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section) paid by such Tax Indemnitee  and any liability
(including penalties, interest, additions to tax and expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted.  The Borrower shall pay any indemnification requested under this Section within 30
days from the date any Tax Indemnitee or  their respective agent (as the case may be) makes written demand therefor.

                  Within 30 days after the date of any payment of Taxes or Other Taxes, the Borrower will furnish to the relevant Tax
Indemnitee the original or a certified copy of a receipt or other documents reasonably acceptable to the relevant Tax Indemnitee
evidencing payment of such Taxes or Other Taxes.

                  If, as a result of an assignment under Section 23(c)(iii) below, a Person organized under the laws of a jurisdiction
outside of the United States becomes a Tax Indemnitee and payments to it to be made under this Agreement are exempt from United
States withholding tax, or are subject to such tax at a reduced rate under an applicable tax treaty, then such assignee shall provide
to the Borrower, promptly following the date that it became a Tax Indemnitee and from time to time thereafter, so long as it is
lawfully able to do so in its reasonable judgment, a properly completed and executed Internal Revenue Service Form 4224 (or new
Form W-8ECI) of Form 1001 (or new Form W-8BEN) or W-9, or any successor form, and any other applicable form, certificate document
prescribed by the Internal Revenue Service certifying as to such assignee's entitlement to such exemption or reduced rate with
respect to all payments to be made to such assignee under this Agreement and any new or other forms or certificates prescribed by the
Internal Revenue Service of the United States in the event that a lapse in time or change in circumstance renders a previous
certification obsolete or inaccurate in any material respect.  Unless the have received forms or other documents satisfactory to them
establishing that payments under this Agreement are not subject to United States withholding tax, or are subject to such tax at a
rate under an applicable tax treaty, the Borrower shall, subject to its obligations under Section 8(a), withhold taxes from such
payments at the applicable statutory rate in the case of payments to or for any Tax Indemnitee, if it is organized under the laws of
a jurisdiction outside the United States.

                  Within 30 days after written request from the Borrower the relevant Tax Indemnitee, as appropriate, shall execute
and deliver to the Borrower such certificates, forms or other documents which can be furnished consistent with the facts and which
are reasonably necessary to assist the Borrower in applying for refunds of Taxes indemnified by the Borrower under this Section.

                  Without prejudice to the survival of any other provision of this Agreement, the agreements and obligations of the
Borrower contained in this Section shall survive the repayment in full of the Loans.

(ii)     Exclusions.  In addition to any exclusions described in Section 8(b)(i) above, the foregoing tax indemnity shall not apply
         ----------
     to:

     Taxes imposed on a Tax Indemnitee resulting from such Tax Indemnitee not claiming any applicable exemption or rate reduction
                  under any applicable law or treaty (unless such Tax Indemnitee provides, at Borrower's expense, an opinion of
                  independent counsel, selected by such Tax Indemnitee and reasonably acceptable to Borrower, that there is no
                  reasonable basis for such claim; provided that, Borrower notifies such Tax Indemnitee in writing that any such
                                                   -------- ----
                  exemption is available and such Tax Indemnitee determines in good faith that neither it nor any Affiliate will be
                  adversely impacted by claiming any such applicable exemption);

                                            Taxes imposed on a Tax Indemnitee resulting from such Tax Indemnitee failing to comply
                  with certification, information, documentation, reporting or similar requirements concerning the nationality,
                  residence, identity or connection with the jurisdiction imposing such Taxes if such Tax Indemnitee was aware of the
                  requirement to comply and such Tax Indemnitee's compliance is required by applicable law or treaty as a precondition
                  to relief or exemption from such Taxes and such Tax Indemnitee was eligible for such relief or exemption, unless
                  such failure to comply was due to failure of Borrower timely to notify the Tax Indemnitee in writing of such
                  requirement or to provide reasonable assistance in complying with such requirement or the Tax Indemnitee determines
                  in good faith that either it or any Affiliate will be adversely impacted by so complying;

                                            Taxes imposed on a Tax Indemnitee resulting from the actual gross negligence (other than
                  gross negligence or willful misconduct imputed or attributed to such Tax Indemnitee by reason of its interest in any
                  Aircraft, Engine or Part) or willful misconduct of such Tax Indemnitee;

                                            Taxes imposed upon a Tax Indemnitee as a result of any transfer by such Tax Indemnitee of
                  any Aircraft, Engine or Part or the Lease or any other Operative Document or of such Tax Indemnitee's interest in
                  any thereof unless such transfer is requested by Borrower or occurs at a time when an Event of Default has occurred
                  and is continuing;

                                            Taxes imposed upon any Tax Indemnitee in its individual capacity based on or measured by
                  fees for services rendered under the Operative Documents; and

                                            Taxes imposed upon any Tax Indemnitee with respect to any period after (1) the
                  termination of the Mortgage, in accordance with the terms thereof and (2) payment of all amounts payable under the
                  Operative Documents having been made.

                                    (For purposes of this Agreement and the other Operative Documents, Taxes, other than those
                  exempted in Section 8(b)(i) or by virtue of clauses (A) through (F) above, are hereinafter referred to as
                  "Indemnified Taxes".)
                  ------------------

                                    In the event of a dispute between Borrower and any Tax Indemnitee regarding the applicability of
                  any of the exclusions described in Section 8(b)(i) or Section 8(b)(ii) or the amount of any Indemnified Taxes,
                  Borrower shall promptly pay to such Tax Indemnitee any amount of Tax claimed to be owed pursuant to Section 8(b)(i),
                  as the case may be.  Any payment made by Borrower pursuant to the immediately preceding sentence shall be refunded
                  by the relevant Tax Indemnitee if it subsequently is on a final and unconditional basis established that such amount
                  was not required to be paid under this Section 8(b)(i) or (b)(ii) hereof, as the case may be.

(iii)    Contest.  If a claim is made against any Tax Indemnitee for any Indemnified Taxes (a "Claim"), such Tax Indemnitee will, as
         -------
     promptly as practical after such tax Indemnitee has received written notification of such Claim, give Borrower written notice of
     such Claim; provided that, a failure to give such notice in a timely manner shall not preclude a Claim for indemnification
                 -------- ----
     hereunder.  If Borrower so requests in writing within thirty (30) calendar days after receipt of such notice, such Tax Indemnitee
     shall consult with Borrower to consider what action may be taken to resist payment of the relevant Indemnified Taxes and
     following such consultation such Tax Indemnitee may take any reasonable action in the name of such Tax Indemnitee to contest the
     Claim in the name of such Tax Indemnitee or, in such Tax Indemnitee's sole discretion, in the name of Borrower, to the extent
     permitted by law; provided that, the following conditions are met:
                       -------- ----

     such Tax Indemnitee shall have received adequate provision satisfactory to it for such Claim and any liability, expense or loss
                  arising out of or related to such contest (including without limitation indemnification for all costs, expenses,
                  losses, reasonable legal and accounting fees and disbursements, penalties and interest);

                                            the contest will not result in any danger of the sale, forfeiture or loss of, or the
                  creation of any Lien on, any Aircraft, any Engine, any Part, or any interest therein unless bonded in a manner and
                  amount acceptable to the Tax Indemnitees;

                                            if such contest shall be conducted in a manner requiring the payment of the Claim,
                  Borrower shall have paid such Claim to the extent required;

                                            no Default or Event of Default shall have occurred and be continuing;

                                            prior to commencing any administrative appeal, Borrower shall have acknowledged its
                  liability to such Tax Indemnitee hereunder for the contested amount;

                                            such Tax Indemnitee shall have received a legal opinion (at the expense of Borrower) from
                  counsel selected by such Tax Indemnitee (and reasonably satisfactory to Borrower) indicating that a reasonable basis
                  for such contest exists; and

                                            such Tax Indemnitee has not received, or does not receive, an opinion from its external
                  tax advisor concluding that the proposed actions to contest such Claim would trigger a significant possibility of
                  creating a local franchise issue of the Tax Indemnitee (e.g. adverse publicity or impairing of the Tax Indemnitee's
                  relationship with local regulators) or impairing the status of other open tax matters (e.g. tax audits) between such
                  Tax Indemnitee and the local taxing authorities.

                                    Notwithstanding the foregoing provisions of this Section 8(b)(iii), if at any time such Tax
                  Indemnitee waives its right of indemnification under this Section 8(b) in respect of a Claim, or if, after having
                  received payment of indemnification from Borrower hereunder in respect of such Claim, such Tax Indemnitee tenders
                  such payment to Borrower, then Borrower shall not be entitled to contest, or to continue to contest, any such Claim.

(iv)     If by reason of any Indemnified Taxes paid or otherwise indemnified against by the Borrower pursuant to this Section 8(b),
     any Tax Indemnitee at any time actually realizes a net reduction in any Taxes not indemnified against by the Borrower and not
     previously taken into account in computing the amount of any indemnity payable by the Borrower under this Section 8(b), such Tax
     Indemnitee shall, so long as no Default or Event of Default shall have occurred, promptly pay to the Borrower an amount that,
     after subtraction of any further Tax savings such Tax Indemnitee realizes as a result of the payment thereof, is equal to the
     amount of such net Tax reduction; provided that any subsequent loss of Tax benefit for which payment has been made to the
     Borrower under this Section 8(b)(iv) (or was taken into account in computing an amount payable by the Borrower under this Section
     8(b)) shall be treated as an indemnifiable Tax hereunder without regard to the exclusions set forth in Sections 8(b)(i) or
     8(b)(ii) hereof.

(c)      Interest.  The Borrower will pay to each Indemnitee on demand, to the extent permitted by applicable law, interest on any
         --------
     amount of indemnity not paid when due pursuant to this Section 8 until the same shall be paid, at the Past Due Rate.

Section 9         Covenants of the Borrower.
                  -------------------------

(a)      Borrower Merger.  For so long as the Mortgage remains in force, the Borrower shall not consolidate with or merge into or
         ---------------
     with any other Person, and not convey, transfer, lease or otherwise dispose of all or substantially all of its property and other
     assets to, or acquire all or any substantial part of the property or other assets or capital stock of (if such acquisition is
     analogous in either purpose or effect to a consolidation or merger), any other Person, unless:

(i)      Such transaction shall not have any material adverse effect on the rights of the Lender, the Administrative Agent or the
     Collateral Agent under or in respect of the Operative Documents or the Aircraft;

     corporation organized and existing under the laws of the United Sates or any state thereof or the District of Columbia;

     substantially all of the property and other assets of the Borrower (if such assets are being transferred) as an entirety, and
     shall have a tangible net worth (determined in accordance with GAAP) of not less than the Borrower's tangible net worth
     (determined in accordance with GAAP) immediately prior to such transaction; (C) shall be a U.S. Air Carrier; and (D) shall
     execute and deliver to the Administrative Agent and Collateral Agent such recordations and filings with any Governmental
     Authority and such other documents as the Administrative Agent or Collateral Agent (at the direction of the Lender) determines
     shall be reasonably necessary or advisable to evidence, or in connection with, such consolidation, merger, sale, lease, transfer
     or other disposition and an agreement, in form and substance reasonably satisfactory to the Administrative Agent or Collateral
     Agent (at the direction of the Lender) which is a legal, valid, binding and enforceable assumption by such Successor Entity of
     the due and punctual performance and observance of each covenant and condition of the borrower under the Operative Documents to
     which the Borrower is a party, and an officer's certificate to such effect and to the effect that the other requirements of this
     Section have been satisfied, and a legal opinion from counsel to such effect and otherwise in such form and substance reasonably
     satisfactory to the Administrative Agent or Collateral Agent (at the direction of the Lender);

(iii)    Such Person shall have a credit rating of "B-" or its equivalent (as determined by S&amp;P or Moody's, as applicable) or higher
     from S&amp;P or the equivalent rating from Moody's; and

         Upon any consolidation or merger in accordance with this Section 9(a), the Successor Entity shall succeed to, and be
substituted for, and may exercise every right and power of, the Borrower under this Agreement with the same effect as if such
Successor Entity had been named as the Borrower herein.

(b)      U.S. Air Carrier.  The Borrower covenants and agrees that at all times during the Term it will be an "air carrier" within
         ----------------
     the meaning of the Federal Aviation Act operating under certificates issued pursuant to Section 40102(a) of such Act and shall
     otherwise meet the standards of the definition of U.S. Air Carrier.

(c)      No Proceedings.  Each of the Borrower, the Administrative Agent, the Collateral Agent and the Lender each hereby agrees
         --------------
     that, from and after the date hereof and until the date one year plus one day following the date on which all Commercial Paper
     has been indefeasibly paid in full in cash, it will not, directly or indirectly, institute or cause to be instituted against the
     Lender or any CP Conduit that becomes a lender any proceeding of the type referred to in the definition of "Bankruptcy Event."
     This Section 9(c) shall survive termination of this Agreement.

(d)      Further Assurances.  The Borrower covenants and agrees with each party hereto as follows:
         ------------------

(i)      The Borrower will cause to be done, executed, acknowledged and delivered all and every such further acts, conveyances and
     assurances as the Lender shall reasonably require for accomplishing the purposes of this Agreement and the other Operative
     Documents; provided that any instrument or other document so executed by the Borrower will not expand any obligations or limit
     any rights of the Borrower in respect of the transactions contemplated by any Operative Documents.  The Borrower shall cause each
     Aircraft to remain duly registered, in the name of the Borrower, except as otherwise required or permitted hereunder or under the
     Mortgage, under the Federal Aviation Act.

(ii)     The Borrower, at its expense, will cause (A) the Mortgage, all Mortgage Supplements and all amendments to the Mortgage to be
     promptly filed and recorded, or filed for recording, to the extent permitted under the Federal Aviation Act, or required under
     any other applicable law and (B) the lien of the Mortgage to at all times be and remain a first priority and perfected Lien on
     the Mortgage Estate.  The Borrower agrees to furnish the Administrative Agent, the Collateral Agent and the Lender with copies of
     the foregoing documents with recording data as promptly as practicable following the issuance of same by the FAA.

(iii)    The Borrower shall pay all reasonable costs and expenses (including costs and disbursements of counsel) incurred by the
     Administrative Agent, the Collateral Agent and the Lender after the date hereof in connection with (x) any supplements or
     amendments of the Operative Documents (including, without limitation, any related recording costs) (other than any supplement or
     amendment associated with a transfer of any Note or the sale of participation interests therein not requested by Borrower),
     (y) any Default and any enforcement or collection proceedings resulting therefrom or in connection with the negotiation of any
     restructuring or "work-out" (whether or not consummated), or (z) the enforcement of this Section 9.

(e)      Liens.  The Borrower will not directly or indirectly create, incur, assume or suffer to exist any Lien on or with respect to
         -----
     the Mortgage Estate, title thereto or any interest therein except (i) the rights of the Borrower as herein provided, the Lien of
     the Mortgage and any other rights existing pursuant to the Operative Documents, (ii) Liens for Taxes of the Borrower either not
     yet due or being contested in good faith by appropriate proceedings (and for which adequate reserves have been provided in
     accordance with generally accepted accounting principles), so long as the continuing existence of such Liens during such
     proceedings do not involve any material risk of the sale, forfeiture or loss of any Airframe or any Engine or any interest
     therein, (iii) mechanics', material suppliers', workers', repairers', employees' or other like Liens arising in the ordinary
     course of the Borrower's business for amounts that are not overdue or are being contested diligently and in good faith by
     appropriate proceedings (and for which adequate reserves have been provided in accordance with generally accepted accounting
     principles), so long as there is not, or the continuing existence of such Liens during such proceedings do not involve, any
     material risk of sale, forfeiture or loss of an Airframe or any Engine or any interest therein, (iv) Liens arising out of any
     judgment or award against the Borrower with respect to which an appeal or proceeding for review is being prosecuted diligently
     and in good faith, so long as such Liens do not result in a material risk of the sale, forfeiture or loss of any Airframe or any
     Engine or any interest therein, (v) the rights of others under agreements or arrangements to the extent expressly permitted by
     the terms of Sections 3.03, 4.02 and 4.04 of the Mortgage, (vi) customary salvage or similar rights of insurers under policies
     required to be maintained by the Borrower under Article VI of the Mortgage, (vii) any other Lien with respect to which the
     Borrower shall have provided a bond or other security in an amount and under terms reasonably satisfactory to the Administrative
     Agent and (viii) Lender Liens.  The Borrower will promptly, at its own expense, take (or cause to be taken) such actions as may
     be necessary duly to discharge any Lien not excepted above if the same shall arise at any time.

(f)      Inspection.  At reasonable times, the Administrative Agent or its authorized representatives on behalf of the Lender, may
         ----------
     inspect the Aircraft and FAA (or other applicable governmental authority) required books and records of the Borrower relating to
     the maintenance of the Aircraft (at the inspecting party's expense (other than in the case of an inspection occurring while an
     Event of Default has occurred and is continuing, in which case the Borrower shall bear the reasonable cost of such inspection))
     and shall keep any information obtained thereby confidential as provided in Section 21 hereof.  Any such inspection of an
     Aircraft shall be upon reasonable advance notice from such inspecting party to the Borrower, shall be during normal business
     hours and shall be a visual, walk-around inspection (including on-board inspection) and may include inspection of areas exposed
     by any open panels, bays or the like, but shall not include opening any panels, bays or the like without the express written
     consent of the Borrower; provided that, so long as no Event of Default shall have occurred and be continuing, no exercise of such
     inspection right shall interfere with the normal operation or maintenance of the Aircraft by, or the business of, the Borrower.
     The Administrative Agent shall have no duty to make any such inspection nor shall it incur any liability or obligation by reason
     of not making any such inspection.

(g)      Amendments, Supplements, Etc.  Forthwith upon the execution and delivery of each Mortgage Supplement from time to time
         -----------------------------

     (as applicable) such further documents and take such further action as the Lender, the Administrative Agent or Collateral Agent
     (on behalf of the Lender) may from time to time reasonably request in order to more effectively carry out the intent and purpose
     of the Mortgage and to establish and protect the rights and remedies created or intended to be created in favor of the
     Administrative Agent, the Collateral Agent and the Lender hereunder and under the Mortgage, including, without limitation, if
     requested by the Administrative Agent or Collateral Agent, at the expense of Borrower, the execution and delivery of supplements
     or amendments hereto, each in recordable form, subjecting to the Mortgage any engine substituted for any Engine pursuant to the

Section 10        The Notes.
                  ---------

(a)      Method of Payment.  Principal and interest and other amounts due hereunder or under the Notes or in respect hereof or
         -----------------
     thereof shall be payable in Dollars in immediately available funds prior to 11:00 a.m., New York, New York time, on the due date
     thereof, to the Administrative Agent at the Payment Office and the Administrative Agent shall, subject to the terms and
     conditions hereof and of the Mortgage, remit all such amounts so received by it to the Lender at the account set forth in
     Schedule I hereto as to such account or accounts at such financial institution or institutions as the Lender may designate to the
     Administrative Agent in writing from time to time, in immediately available funds for distribution to the Lenders, such payment
     to be made, in the case of any such designated account in New York, New York, prior to 1:00 p.m., New York time, on the due date
     thereof.  In the event the Borrower 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 Administrative Agent agrees to compensate the Lender
     for loss of use of funds in a commercially reasonable manner.  All such payments by the Borrower and the Administrative Agent
     shall be made free and clear of and without reduction on account of all wire and other like charges.  All amounts paid hereunder
     by Borrower shall be paid free of any taxes, levies, imposts, charges, duties or withholding of any kind, except for (i) taxes
     related to the income of the Lender, the Administrative Agent or the Collateral Agent and (ii) taxes incurred as a result of the
     gross negligence or willful misconduct of the Lender, the Administrative Agent or the Collateral Agent.  Prior to the due
     presentment for registration of transfer of any Note, the Borrower and the Administrative Agent may deem and treat the Person in
     whose name any Note is registered on the Note Register as the absolute owner of such Note for the purpose of receiving payment of
     all amounts payable with respect to such Note and for all other purposes whether or not such Note shall be overdue, and neither
     the Borrower nor the Administrative Agent shall be affected by any notice to the contrary.

(b)      Application of Payments.  Except as otherwise expressly provided herein, each payment of principal and interest or other
         -----------------------
     amounts due in respect of each Note shall be distributed to the Lender ratably, without priority of any one Note over any other
     Note, in the proportion that the amount of such payment or payments then due under each Note bears to the aggregate amount of the
     payments then due under all Notes.  Each such payment shall, except as otherwise expressly provided herein, be applied, first, to
                                                                                                                             -----
     the payment of any amount (other than the principal of or interest on such Note) due in respect of such Note, second, to the
                                                                                                                   ------
     payment of interest on such Note (as well as any interest on overdue principal and, to the extent permitted by law, interest and
     other amounts payable thereunder) due thereunder, third, to the payment of the principal of such Note then due and fourth, the
                                                       -----                                                            ------
     balance, if any, remaining thereafter, to the payment of the principal of such Note remaining unpaid (provided that such Note
     shall not be subject to prepayment without the consent of the Lender except as permitted by Sections 10(f) and 10(g) hereof).
     The amounts paid pursuant to clause fourth above shall be applied to the installments of principal of such Note in inverse order
                                         ------
     of maturity.

(c)      Registration, Transfer and Exchange of Notes.  The Administrative Agent agrees with the Borrower that the Administrative
         --------------------------------------------
     Agent shall keep a register (herein sometimes referred to as the "Note Register") in which provision shall be made for the
                                                                       -------------
     registration of Notes of each Series and the registration of transfers of Notes of such Series.  Prior to the due presentment for
     registration of the transfer of any Note, the Borrower and the Administrative Agent shall deem and treat the person in whose name
     such Note is registered on the Note Register as the absolute owner of such Note, and the Lender for the purpose of receiving
     payment of all amounts payable with respect to such Note, and for all other purposes whether or not such Note is overdue, and
     neither the Borrower nor the Administrative Agent shall be affected by notice to the contrary.  The Note Register shall be kept
     at the office of the Administrative Agent or at the office of any successor Administrative Agent, and the Administrative Agent is
     hereby appointed "Note Registrar" for the purpose of registering Notes and transfers of Notes as herein provided.  Subject to
     Section 23(c) hereof, upon surrender for registration of transfer of any Note of any Series at the Payment Office and upon
     delivery by the Administrative Agent to the Borrower of such surrendered Note, the Borrower shall execute, and the Administrative
     Agent shall deliver, in the name of the designated transferee or transferees, one or more new Notes of a like aggregate principal
     amount and Series.  At the option of the Lender, its Notes of any Series may be exchanged for other Notes of such Series of any
     authorized denominations, of a like aggregate principal amount, upon surrender of the Notes to be exchanged at the Payment
     Office.  Each new Note issued upon transfer or exchange shall be in a principal amount of at least $5,000,000 (except as may be
     necessary to evidence the entire outstanding principal amount of a Note) and dated the Delivery Date of the Aircraft of the
     related Series.  Whenever any Notes are so surrendered for exchange, the Borrower shall execute and deliver the Notes which the
     Lender making the exchange is entitled to receive.  All Notes issued upon any registration of transfer or exchange of Notes shall
     be the valid obligations of the Borrower evidencing the same respective obligations, and entitled to the same security and
     benefits under the Mortgage, as the Notes surrendered upon such registration of transfer or exchange.  Every Note presented or
     surrendered for registration of transfer or exchange, shall (if so required by the Administrative Agent) be duly endorsed, or be
     accompanied by a written instrument of transfer in form satisfactory to the Administrative Agent duly executed by the Lender or
     its attorney duly authorized in writing, and the Administrative Agent may 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 Administrative
     Agent shall make a notation on each new Note or Notes of the amount of all payments of principal previously made on the old Note
     or Notes with respect to which such new Note is issued and the date to which interest accrued on such old Note or Notes has been
     paid.  The Administrative Agent shall not be required to register the transfer of or exchange any surrendered Notes as above
     provided during the five calendar day period preceding the due date of any payment on such Notes.  The Administrative Agent shall
     give the Borrower and the Lender notice of each transfer of a Note under this Section 10(c).  Any such transferee of a Note, by
     its acceptance of a Note, agrees to the provisions of the Operative Documents applicable to the Lender, and shall be deemed to
     have covenanted to the parties to the Operative Documents as to the matters covenanted by the original Lender therein; provided
                                                                                                                            --------
     that no transferee of a Note shall be entitled to receive any greater amount pursuant to Section 10(h) of this Agreement than the
     transferor of such Note would have been entitled to receive had no such transfer occurred.

(d)      Mutilated, Destroyed, Lost or Stolen Notes.  If any Note shall become mutilated, destroyed, lost or stolen, the Borrower
         ------------------------------------------
     shall, upon the written request of the Lender, execute and deliver in replacement thereof, a new Note of a like Series, in the
     same principal amount, dated the date of such Note and designated as issued under the Mortgage.  If the Note being replaced has
     become mutilated, such Note shall be surrendered to the Administrative Agent and the original thereof shall be furnished to the
     Borrower by the Administrative Agent.  If the Note being replaced has been destroyed, lost or stolen, the Lender shall furnish to
     the Borrower and the Administrative Agent such security or indemnity as may be reasonably required by them to hold the Borrower
     and the Administrative Agent harmless and evidence satisfactory to the Borrower and the Administrative Agent of the destruction,
     loss or theft of such Note and of the ownership thereof; provided, however, that if the Lender is an original party hereto or an
                                                              --------  -------
     Affiliate thereof, the written notice of such destruction, loss or theft and such ownership and the written undertaking of the
     Lender delivered to the Borrower and the Administrative Agent to hold harmless the Borrower and the Administrative Agent in
     respect of the execution and delivery of such new Note shall be sufficient evidence, security and indemnity.

(e)      Payment of Expenses on Transfer.  Upon the issuance of a new Note or new Notes pursuant to Sections 10(c) or (d), the
         -------------------------------
     Borrower and/or the Administrative Agent may require from the party requesting such new Note or Notes payment of a sum sufficient
     to reimburse the Borrower and/or the Administrative Agent for, or to provide funds for, the payment of any tax or other
     governmental charge in connection therewith or any charges and expenses connected with such tax or other governmental charge paid
     or payable by the Borrower or the Administrative Agent.

(f)      Prepayment.  (i)  (i)      On at least five Business Days' prior written notice, the Borrower may prepay on the date
         ----------
     specified in its notice of prepayment delivered pursuant to this Section 10(f) in whole, or in part, the Notes of any Series then
     outstanding at the principal amount thereof (or portion thereof to be repaid), together with accrued interest thereon to the date
     of prepayment plus all Break Amount and Swap Breakage Amount and Additional Costs, if any, and all other amounts due to the
     Lender hereunder, thereunder and under the other Operative Documents; provided that any partial prepayment shall be in an
     aggregate original principal amount of at least $5,000,000 and in $1,000,000 multiples thereof, and the amount thereof shall be
     specified in such written notice.  The Administrative Agent will give prompt notice to the Lender of the Borrower's intent to
     prepay any Note.

(ii)     On at least five Business Days' prior written notice, the Borrower shall prepay on the date specified in its notice of
     prepayment delivered pursuant to this Section 10(f) the Notes of any Series in full, but not in part, together with accrued
     interest thereon to the date of prepayment plus all Break Amount and Swap Breakage Amount and Additional Costs, if any, and all
     other amounts due thereunder and hereunder and under the other Operative Documents to the Lender upon the occurrence of an Event
     of Loss with respect to the related Airframe; such prepayment shall, in any event, be no later than the last day permitted for
     such payment under Section 5.01 of the Mortgage.  The Administrative Agent will give notice of prepayment to the Lender under
     this Section 10(f)(ii) promptly.

(iii)    Any notice of prepayment delivered pursuant to paragraph (i) or (ii) above shall be irrevocable if not revoked within five
     Business Days of the specified date of payment and shall identify the amount to be prepaid and the Series of Notes subject to
     prepayment.

(g)      Provisions Relating to Prepayment.  (i)  (i)         Notice of prepayment having been given and not revoked as aforesaid, the
         ---------------------------------
     principal amount of the Notes so to be prepaid, plus accrued interest thereon to the date of prepayment, together with the Swap
     Breakage Amount and Break Amount and Additional Costs, if any, herein provided, shall become due and payable on the prepayment
     date.

(ii)     On the date fixed for prepayment under Section 10(f), immediately available funds in Dollars shall be deposited by the
     Borrower in the account of the Administrative Agent at the place and by the time and otherwise in the manner provided in
     Section 10(a), in an amount equal to the principal amount of Notes to be prepaid together with accrued and unpaid interest
     thereon to the date fixed for such prepayment, all Swap Breakage Amount and Break Amount and Additional Costs, if any, and all
     other amounts due to the Lender hereunder, thereunder and under the other Operative Documents.

(iii)    The Lender shall furnish to the Borrower, with a copy to the Administrative Agent, a certificate setting forth in reasonable
     detail the calculation of the amounts of Swap Breakage Amount and Break Amount due to the Lender, which certificate shall be
     presumptively correct absent manifest error.

(h)      Increased Costs.  (i)  (i) The Borrower shall pay to the Administrative Agent for the account of the Lender from time to time
         ---------------
     such amounts as the Lender (or its agent) may determine to be necessary to compensate the Lender for any increase in actual costs
     that the Lender determines are attributable to its making, funding or maintaining its Commitment or the Loans or any reduction in
     any amount receivable by the Lender hereunder in respect of any of its Commitments or the Loans (including, without limitation,
     any such increases or reductions attributable to any CP Program or other funding arrangement utilized by the Lender in funding
     the Loans) (such increases in costs and reductions in amounts receivable being herein called "Additional Costs"), resulting from
     any Regulatory Change that:

     imposes any tax that is the functional equivalent of any reserve, special deposit or similar requirement of the sort covered by
                  clause (ii) below; or

                                            imposes or modifies any reserve, special deposit or similar requirements (including any
                  Reserve Requirement) relating to any extensions of credit or other assets of, or any deposits with or other
                  liabilities of, the Lender (including, without limitation, any of such loans or any deposits referred to in the
                  definition of "LIBOR" in Section 1.01 of the Mortgage), or any such obligations; or

                                            imposes any other condition affecting the Mortgage, or its Notes (or any of such
                  extensions of credit or liabilities) or any such obligation.

(ii)     Without limiting the effect of the foregoing provisions of this Section 10(h) (but without duplication), the Borrower shall
     pay to the Administrative Agent for the account of the Lender from time to time on request such amount as the Lender may
     determine to be necessary to compensate the Lender (or, without duplication, the holding company of which the Lender is a
     subsidiary) for any increase in actual costs that it determines are attributable to the maintenance by the Lender (or any lending
     office or such holding company) of its Commitment hereunder, resulting from the implementation of any risk-based capital
     guideline, reserve requirement or other similar requirement hereafter issued by any Governmental Authority pursuant to any law or
     regulation or any interpretation, directive or request (whether or not having the force of law and whether or not failure to
     comply therewith would be unlawful so long as compliance therewith is standard banking practice in the relevant jurisdiction)
     (including, without limitation, implementing at the national level the Basel Accord), the effect of which would be to reduce the
     return on investment of capital in respect of its Commitments or Loans, including, without limitation, any such reduction
     attributable to any CP Program or other funding arrangements utilized by the Lender in connection with the Loans or funding
     arrangements utilized in connection with the Loans; such compensation shall include, without limitation, an amount equal to any
     reduction of the rate of return on assets or equity of the Lender (or any lending office or such bank holding company) could have
     achieved but for such law, regulation, interpretation, directive or request.  For purposes of this Section 10(h)(ii), "Basel
     Accord" shall mean the "New Basel Capital Accord" issued by the Basel Committee of Banking Supervision on January 16, 2001, as
     amended.

(iii)    The Lender (or the Administrative Agent on its behalf) shall notify the Borrower of any event occurring after the date
     hereof entitling the Lender to compensation under paragraph (i) or (ii) of this Section 10(h) as promptly as practicable, but in
     any event within 60 days, after the Lender obtains actual knowledge thereof; provided that (A) the Lender shall, with respect to
                                                                                  --------
     compensation payable pursuant to this Section 10(h) in respect of any Additional Costs resulting from such event, only be
     entitled to payment under this Section 10(h) for Additional Costs incurred from and after the date that is 60 days prior to the
     date the Lender (or the Administrative Agent or Collateral Agent on its behalf) does give such notice and (B) the Lender will use
     commercially reasonable efforts (at the Borrower's expense) to mitigate the amount of the Additional Costs associated with such
     event, including designating a different lending office for the Notes of the Lender affected by such event if such designation
     will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of the Lender, result in
     any economic, legal or regulatory disadvantage to the Lender (other than economic disadvantages for which the Borrower agrees to
     indemnify the Lender and which indemnity is acceptable to the Lender in its discretion acting reasonably based on its credit
     assessment of the Borrower).  The Lender (or the Administrative Agent or Collateral Agent on its behalf) will furnish to the
     Borrower an officer's certificate setting forth in reasonable detail (x) the events giving rise to such Additional Costs, (y) the
     basis for determining and allocating such Additional Costs and (z) the amount of each request by the Lender for compensation
     under paragraph (i) or (ii) of this Section 10(h) (subject, however, to any limitations the Lender may require in respect of
     disclosure of confidential information relating to its capital structure), together with a statement that the determinations and
     allocations made in respect of the Additional Costs comply with the provisions of this Section 10(h), including as provided in
     the last proviso of this paragraph (iii).  Determinations and allocations by the Lender for purposes of this Section 10(h) of the
     effect of any Regulatory Change pursuant to paragraph (i) of this Section 10(h), or of the effect of capital maintained pursuant
     to paragraph (ii) of this Section 10(h), on its costs or rate of return of maintaining Notes or its funding, or on amounts
     receivable by it in respect of Notes, and of the amounts required to compensate the Lender under this Section 10(h), shall be
     conclusive absent manifest error, provided that such determinations and allocations are made on a reasonable basis and, in the
                                       --------
     case of allocations, are made fairly.

(iv)     If the Lender gives notice of a claim against the Borrower under this Section 10(h), the Borrower shall have the right
     (i) to require the Lender to sell its Notes to an institution designated by the Borrower in compliance with Section 23(c)(iii) of
     this Agreement for an amount equal to the outstanding principal amount thereof plus accrued interest thereon to the date of sale,
     together with the Swap Breakage Amount and Break Amount, if any, or (ii) to prepay the outstanding principal amount of Notes held
     by the Lender, together with accrued interest to the date of such prepayment and the Swap Breakage Amount and Break Amount, if
     any.

(v)      The Borrower shall not be required to make payments under this Section 10(h) to the Lender if (A) a claim hereunder arises
     solely through circumstances peculiar to the Lender and which do not affect commercial lenders similar to the Lender or CP
     Conduits, as applicable, in the United States generally or (B) the claim arises out of a voluntary relocation by the Lender of
     its lending office (it being understood that any such relocation effected pursuant to Section 10(h)(iii)(B) is not "voluntary"),
     or (C) the Lender is required by the Borrower pursuant to Section 10(h)(iv) above to sell its Notes to a purchaser designated by
     the Borrower and fails to do so.

     consecutive days, or an order, judgment or decree shall be entered in any proceeding by any court of competent jurisdiction
     appointing, without the consent of the Borrower, a receiver, trustee or liquidator of the Borrower, or for all or substantially
     all of its property, or sequestering of all or substantially all of the property of the Borrower and any such order, judgment or
     decree or appointment or sequestration shall be final or shall remain in force undismissed, unstayed or unvacated for a period of
     sixty (60) consecutive days after the date of entry thereof; or

(viii)   The Borrower fails or ceases to be a U.S. Air Carrier or shall have been suspended as a U.S. Air Carrier or shall otherwise
     no longer have all applicable licenses (or such licenses shall be suspended) necessary to operate as a commercial airline; or

(ix)     Immediately upon such time as the Mortgage ceases to create a valid, perfected first priority mortgage on any Airframe or
     Engine in favor of the Collateral Agent on behalf of the Lender for any reason other than the failure of the Lender to cause
     continuation statements to be filed to the extent required by the Uniform Commercial Code or the filing by or on behalf of the
     Lender of a termination statement releasing such Airframe or Engine from the Lien of the Mortgage.

(b)      Certain Rights of Administrative Agent.
         --------------------------------------

(i)      In anticipation of receipt from Borrower of payment of sums due and owing hereunder or under any Operative Document, the
     Administrative Agent shall have the option, but shall not be obligated to, advance to the Lender on any Interest Payment Date, as
     provided in Section 10(a) hereof, an amount equal to that required to be paid to the Lender by the Borrower on such Interest
     Payment Date.

(ii)     The Administrative Agent shall not, as a result of exercising its option to make the advance described in Section 11(b)(i)
     above, obtain any Lien on the Mortgage Estate for or on account of costs or expenses incurred in connection with the exercise of
     such right, nor shall any claim of the Administrative Agent against the Borrower or any other party for the repayment of such
     costs or expenses impair the prior right and security interest of the Collateral Agent (on behalf of the Lender) in and to the
     Mortgage Estate.  Upon any advance by the Administrative Agent to the Lender as provided in Section 11(b)(i), the Administrative
     Agent shall be subrogated to the rights of the Lender in respect of any late payment made by Borrower and interest at the Past
     Due Rate payable by the Borrower on account of its being overdue (but shall have no rights as a secured party hereunder), and
     thereafter, the Administrative Agent shall be entitled to receive such overdue payment and such interest; provided, that the
     Administrative Agent shall not be entitled to seek recovery of any such advance (or any payment in lieu thereof) except pursuant
     to the foregoing right of subrogation.

Section 12        Remedies.
                  --------

(a)      General; Acceleration.  (i)  (i)   If an Event of Default shall have occurred and be continuing and so long as the same
         ---------------------
     shall be continuing, then and in every such case, the Lender may exercise any or all of the rights and powers and pursue any and
     all of the remedies pursuant to this Section 12 and shall have and in addition, may exercise all of the rights and remedies of a
     secured party under the Uniform Commercial Code.

(ii)     If an Event of Default referred to in Sections 11(f) or 11(g) shall have occurred, then and in every such case the unpaid
     principal of all Notes then outstanding, together with interest accrued but unpaid thereon, and all other amounts due to the
     Lender thereunder and hereunder and under the other Operative Documents, shall, unless the Administrative Agent, acting upon the
     instructions of the Lender shall otherwise direct, immediately and without further act become due and payable, without
     presentment, demand, protest or notice, all of which are hereby waived.

(iii)    If any other Event of Default shall have occurred and be continuing, then and in every such case, the Lender may at any
     time, by written notice or notices to the Borrower, declare all the Notes to be due and payable, whereupon the unpaid principal
     of all Notes then outstanding, together with interest accrued but unpaid thereon, and all other amounts due to the Lender
     thereunder, hereunder and under the other Operative Documents, shall immediately and without further act become due and payable
     without presentment, demand, protest or other notice, all of which are hereby waived.

(iv)     If the principal of the Notes shall have become due and payable pursuant to this Section 12(a), there shall also become due
     and payable, to the fullest extent permitted by law, to the Lender upon demand, without presentment, protest or notice, all of
     which are hereby waived, the Break Amount, Swap Breakage Amount and Additional Costs (if any) therefor.

(v)      The Lender shall be entitled, at any sale pursuant to this Section 12, to credit against any purchase price bid at such sale
     by the Lender all or any part of the unpaid obligations owing to the Lender and secured by the Lien of the Mortgage.  The
     Collateral Agent and the Lender shall, upon any such purchase, acquire good title to the property so purchased, to the extent
     permitted by applicable law, free of all rights of redemption.

(vi)     The Lender agrees to give to the Borrower at least ten days' prior written revocable notice of any foreclosure of the Lien
     of the Mortgage, or of any other action to cause the Borrower to lose its title in an Aircraft (which period of notice the
     parties hereto confirm is commercially reasonable).

(b)      Repossession and Sale.  At any time during the continuation of an Event of Default, the Collateral Agent, as directed by the
         ---------------------
     Lender, or the Administrative Agent on its behalf, in addition to any rights it might otherwise have at law, may do either or
     both of the following:

(i)      Upon the written demand of the Collateral Agent, and at the Borrower's expense, cause the Borrower to return promptly, and
     the Borrower shall return promptly, all or any part of any Aircraft as the Collateral Agent may so demand, to the Collateral
     Agent at a major airport on the Borrower's route system in one of the forty eight (48) contiguous states of the United States of
     America chosen by the Collateral Agent in the manner and condition required by Section 3.01 of the Mortgage, or, alternatively,
     the Collateral Agent at its option, may, to the extent permitted by law, peaceably enter upon the premises where all or any part
     of an Aircraft is located and take immediate possession of and remove the same by summary proceedings or otherwise (and, at the
     Collateral Agent's option store the same at the Borrower's premises until disposal thereof by the Collateral Agent), all without
     liability accruing to the Collateral Agent for or by reason of such entry or taking of possession or removal so long as the
     Collateral Agent has acted in accordance with the provisions of the Mortgage; provided that during any period an Aircraft is
                                                                                   -------- ----
     activated under CRAF in accordance with the provisions of Section 3.03 of the Mortgage and in the possession of the government of
     the United States of America or an instrumentality or agency thereof, the Collateral Agent shall not, on account of any Event of
     Default, be entitled to do any of the following in such manner as to limit the Borrower's control under the Mortgage of the
     associated Airframe or any Engines installed thereon, unless at least sixty (60) days' (or such lesser period as may then be
     applicable under the Military Airlift Command program of the government of the United States of America) prior written notice of
     default hereunder shall have been given by the Collateral Agent by registered or certified mail to the Borrower with a copy
     addressed to the Contracting Office Representative for the Military Airlift Command of the United States Air Force under the
     contract with the Borrower relating to such Aircraft; or

(ii)     with or without taking possession thereof, sell all or any part of any Aircraft at public or private sale, as the Collateral
     Agent may determine, or otherwise dispose of, hold, use, operate or lease to others, as the Administrative Agent, in its sole
     discretion, may determine, all free and clear of any rights of the Borrower, except as hereinafter set forth in this Section 12.

                  In addition, the Borrower shall be liable, except as otherwise provided above and without duplication of amounts
payable hereunder, for any and all reasonable and actual legal fees and other costs and expenses incurred by the Collateral Agent,
the Administrative Agent and the Lender in connection with the enforcement of any of their respective rights and remedies hereunder.

                  At any sale of an Aircraft or any part thereof pursuant to this Section 12, the Collateral Agent, at the Lender's
direction, or the Administrative Agent on the Lender's behalf, may bid for and purchase such property.  The Collateral Agent, at the
Lender's direction, or the Administrative Agent on the Lender's behalf, agrees to give the Borrower at least ten days' written notice
of the date fixed for any public sale of any Airframe or any Engine or of the date on or after which will occur the execution of any
contract providing for any private sale (together with details thereof).  Except as otherwise expressly provided above, no remedy
referred to in this Section 12 is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred
to above or otherwise available to the Collateral Agent at law or in equity; and the exercise or beginning of exercise by the
Collateral Agent of any one (1) or  more of such remedies shall not preclude the simultaneous or later exercise by the Collateral
Agent of any or all of such other remedies.  No express or implied waiver by the Collateral Agent of any Event of Default shall in
any way be, or be construed to be, a waiver of any future or subsequent Event of Default.

(c)      Taking of Aircraft.  (i)  (i)      If an Event of Default shall have occurred and be continuing, at the request of the
         ------------------
     Collateral Agent, at the direction of the Lender (or the Administrative Agent on its behalf), the Borrower shall promptly execute
     and deliver to the Collateral Agent such instruments of title and other documents as the Collateral Agent, at the direction of
     the Lender (or the Administrative Agent on its behalf), may deem necessary or advisable to enable the Collateral Agent or an
     agent or representative designated by the Collateral Agent, at such time or times and place or places as the Collateral Agent may
     specify, to obtain possession of all or any part of the Mortgage Estate to which the Collateral Agent, at the direction of the
     Lender (or the Administrative Agent on its behalf), shall at the time be entitled hereunder.  If the Borrower shall for any
     reason fail to execute and deliver such instruments and documents after such request by the Collateral Agent, the Collateral
     Agent, at the direction of the Lender (or the Administrative Agent on its behalf), may (A) obtain a judgment conferring on the
     Collateral Agent the right to immediate possession and requiring the Borrower to execute and deliver such instruments and
     documents to (or as delivered by) the Collateral Agent, to the entry of which judgment the Borrower hereby specifically consents,
     and (B) pursue all or part of the Mortgage Estate wherever such Mortgage Estate may be found and may peaceably enter any of the
     premises of the Borrower wherever it may be or be supposed to be and search for and take possession of and remove the same.  All
     expenses of obtaining such judgment or of pursuing, searching for and taking such property shall, until paid, be secured by the
     Lien of the Mortgage.

(ii)     Upon every such taking of possession, the Collateral Agent, at the direction of the Lender (or the Administrative Agent on
     its behalf), may, from time to time, at the expense of the Mortgage Estate, make all such expenditures for maintenance,
     insurance, repairs, replacements, alterations, additions and improvements to and of the Mortgage Estate, as it may deem proper.
     In each such case, the Collateral Agent shall have the right to maintain, use, operate, store, lease, control or manage the
     Mortgage Estate and to carry on the business and to exercise all rights and powers of the Borrower relating to the Mortgage
     Estate, as the Collateral Agent, at the direction of the Lender (or the Administrative Agent on its behalf), shall deem best,
     including the right to enter into any and all such agreements with respect to the maintenance, insurance, use, operation,
     storage, leasing, control, management or disposition of the Mortgage Estate or any part thereof as the Collateral Agent, at the
     direction of the Lender (or the Administrative Agent on its behalf), may determine; and the Collateral Agent shall be entitled to
     collect and receive directly all tolls, rents, revenues, issues, income, products and profits of the Mortgage Estate and every
     part thereof.  Such tolls, rents, revenues, issues, income, products and profits shall be applied to pay the expenses of the use,
     operation, storage, leasing, control, management or disposition of the Mortgage Estate and of conducting the business thereof,
     and of all maintenance, repairs, replacements, alterations, additions and improvements, and to make all payments which the
     Collateral Agent may be required or may elect to make, if any, for taxes, assessments, insurance or other proper charges upon the
     Mortgage Estate or any part thereof (including the employment of engineers and accountants to examine, inspect and make reports
     upon the properties and books and records of the Borrower), and all other payments which the Collateral Agent may be required or
     authorized to make under any provision of the Mortgage, as well as just and reasonable compensation for the services of the
     Collateral Agent pursuant to this Section 9.03(b), and of all persons properly engaged and employed by the Collateral Agent.

(d)      Discontinuance of Proceedings.  In case the Collateral Agent, at the direction of the Lender (or the Administrative Agent on
         -----------------------------
     its behalf), or the Administrative Agent on behalf of the Lender shall have instituted any proceeding to enforce any right, power
     or remedy under the Mortgage by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned
     for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case, the Collateral Agent
     and the Borrower shall, subject to any determination in such proceedings, be restored to their former positions and rights
     hereunder with respect to the Mortgage Estate, and all rights, remedies and powers of the Collateral Agent shall continue as if
     no such proceedings had been instituted.

(e)      Waiver of Past Defaults.  The Administrative Agent, upon written instructions from the Lender, shall waive any past Default
         -----------------------
     or Event of Default hereunder and its consequences and upon any such waiver such Default or Event of Default shall cease to exist
     and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Agreement, but no such
     waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

(f)      Remedies Cumulative.  Each and every right, power and remedy given to the Collateral Agent, the Administrative Agent or the
         -------------------
     Lender specifically or otherwise herein shall be cumulative and shall be in addition to every other right, power and remedy
     herein specifically given or now or hereafter existing at law, in equity or by statute, and each and every right, power and
     remedy whether specifically herein given or otherwise existing may be exercised from time to time and as often and in such order
     as may be deemed expedient by the Collateral Agent, the Administrative Agent or the Lender and the exercise or the beginning of
     the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter
     any other right, power or remedy.  No delay or omission by the Collateral Agent, the Administrative Agent or the Lender in the
     exercise of any right, remedy or power or in the pursuit of any remedy shall impair any such right, power or remedy or be
     construed to be a waiver of any default on the part of the Borrower or to be an acquiescence therein.

(g)      Payment After Event of Default, etc.  All payments received and amounts held or realized by the Collateral Agent or the
         ------------------------------------
     Administrative Agent after an Event of Default shall have occurred and so long as such Event of Default shall be continuing, and
     after the Notes shall have been accelerated pursuant to Section 12(a) hereof or after the Lender, the Administrative Agent or the
     Collateral Agent shall foreclose or enforce the Mortgage or after the Notes shall have become due and payable as provided in
     Section 12(a)(ii) or (iii), as well as all payments or amounts then held by the Administrative Agent as part of the Mortgage
     Estate, shall be promptly distributed by the Administrative Agent in the following order of priority:

                  first, so much of such payments or amounts as shall be required to reimburse the Collateral Agent, Administrative
                  -----
         Agent or the Lender for any tax, expense, charge or other loss (including, without limitation, all amounts to be expended at
         the expense of, or charged upon the tolls, rents, revenues, issues, income, products and profits of, the property included
         in the Mortgage Estate pursuant to Section 12(c)(ii)) incurred by the Collateral Agent, the Administrative Agent or the
         Lender (to the extent not previously reimbursed) (including, without limitation, the expenses of any sale, taking or other
         proceeding, reasonable attorneys' fees and expenses, court costs, and any other expenditures incurred or expenditures or
         advances made by the Collateral Agent, in the protection, exercise or enforcement of any right, power or remedy or any
         damages sustained by the Collateral Agent, liquidated or otherwise, upon such Event of Default) shall be applied by the
         Administrative Agent in reimbursement of such expenses;

                  second, so much of such payments or amounts remaining as shall be required to pay in full to the Lender all other
                  ------
         amounts payable pursuant to the indemnification provisions hereof or pursuant to any other provision of any Operative
         Document and secured hereunder (other than amounts payable pursuant to clause "fourth" of this Section 12(g)) to the Lender
                                                                                        ------
         and remaining unpaid, including Break Amount and Swap Breakage Amount and Additional Costs, shall be distributed to such
         Persons, and if the aggregate amount remaining shall be insufficient to pay all such amounts in full, it shall be
         distributed ratably, without priority of such person over any other;

                  third, so much of such payments or amounts remaining as shall be required to pay in full the aggregate unpaid
                  -----
         principal amount of and all accrued but unpaid interest to the date of distribution on, the Notes shall be distributed to
         the Lender, and if the aggregate amount remaining shall be insufficient to pay all such amounts in full, it shall be
         distributed ratably, without priority of any such person over any other, in the proportion that the principal amount of and
         all accrued but unpaid interest to the date of distribution on, each Note bears to the aggregate principal amount of and all
         accrued but unpaid interest to the date of distribution on all Notes; and

                  fourth, the balance, if any, of such payments or amount remaining thereafter shall be distributed to the Borrower or
                  ------
         as a court of competent jurisdiction shall direct.

Section 13        Replacement Engines.
                  -------------------

(a)      Replacement Engines.  At any time and from time to time, any Engine which has been (or is to be treated as if the same had
         -------------------
     been) subject to an Event of Loss and may be replaced under Section 5.02 of the Mortgage by a Replacement Engine shall be
     replaced in accordance with the provisions of this Section 13(a) and the Borrower shall, from time to time, direct the Collateral
     Agent to execute and deliver to or as directed in writing by an appropriate instrument releasing such Engine from the Lien of the
     Mortgage, the Administrative Agent on behalf of the Lender shall execute and deliver such instrument as aforesaid, but only upon
     receipt by or deposit with the Administrative Agent of the following:

(i)      A written request from the Borrower, requesting such release and specifically describing the Engine(s) so to be released.

(ii)     A certificate signed by a duly authorized officer of the Borrower stating the following with respect to the replacement of
     any Engine:

     the fair market value of the Replacement Engine as of the date of such certificate (which value shall not be less than the then
                  fair market value of the Engine requested to be released, assuming such Engine was in the condition and repair
                  required to be maintained (but without regard to hours and cycles until overhaul));

                                            the fair market value of the Engine to be released (immediately prior to the date such
                  Engine suffered an Event of Loss);

                                            that the release of the Engine so to be released will not impair the security of the
                  Mortgage or be in contravention of any of the provisions of the Mortgage; and

                                            that each of the conditions specified in Section 5.02 of the Mortgage with respect to
                  such Replacement Engine have been satisfied.

(b)      Mortgage Supplements for Replacements.  In the event of a Replacement Engine being substituted as contemplated by
         -------------------------------------
     Section 5.02 of the Mortgage, the Borrower, the Collateral Agent and the Administrative Agent agree for the benefit of the
     Lenders, subject to fulfillment of the conditions precedent and compliance by the Borrower with its obligations set forth in
     Section 5.02 of the Mortgage and the requirements of Section 13(a) with respect to such Replacement Engine, to execute and
     deliver a Mortgage Supplement with respect thereto as contemplated by Section 5.02 of the Mortgage, and, provided no Default or
     Event of Default in each case under Section 11 hereof shall have occurred and be continuing, to execute and deliver to the
     Borrower an appropriate instrument releasing the Engine being replaced from the Lien of the Mortgage (which may be the Mortgage
     Supplement that adds the Replacement Engine to the Mortgage).

(c)      Effect of Replacement.  In the event of the substitution of a Replacement Engine pursuant to Section 5.02 of the Mortgage
         ---------------------
     and Section 13(a) hereof, all provisions of this Agreement and the Mortgage relating to an Engine or Engines being replaced shall
     be applicable to such Replacement Engine or Engines with the same force and effect as if such Replacement Engine or Engines were
     the same engine or engines as the Engine or Engines being replaced but for the Event of Loss with respect to an Engine or Engines
     being replaced.

Section 14        The Agents.
                  ----------

(a)      Appointment, Powers and Immunities.  The Lender hereby appoints and authorizes PK AirFinance S.A., New York Branch ("PK") to
         ----------------------------------                                                                                   --
     act as its Administrative Agent hereunder and under the other Operative Documents, and GE Capital to act as its Collateral Agent
     hereunder and under the other Operative Documents, with such powers as are specifically delegated to the Administrative Agent and
     Collateral Agent, respectively, by the terms of this Agreement and of the other Operative Documents, together with such other
     powers as are reasonably incidental thereto.  The Administrative Agent and Collateral Agent shall be referred to collectively as
     the "Agents" for purposes of this Article.  The Agents shall take all actions delegated to them (respectively) hereunder as an
     agent solely for the benefit of the Lender.  The Agents (which term as used in this sentence and in Section 14(c) and the first
     sentence of Section 14(f) hereof shall include reference to their Affiliates and their own and their Affiliates' officers,
     directors, employees and agents, or either of them):  (i) shall have no duties or responsibilities except those expressly set
     forth in this Agreement and in the other Operative Documents, and shall not by reason of this Agreement or any other Operative
     Document be a trustee for the Lender; (ii) shall not be responsible to the Lender for any recitals, statements, representations
     or warranties contained in this Agreement or in any other Operative Document, or in any certificate or other document referred to
     or provided for in, or received by any of them under, this Agreement or any other Operative Document, or for the value, validity,
     effectiveness, genuineness, enforceability or sufficiency of this Agreement, any Note or any other Operative Document or any
     other document referred to or provided for herein or therein or for any failure by the Borrower or any other Person to perform
     any of its obligations hereunder or thereunder; (iii) shall not be required to initiate or conduct any litigation or collection
     proceedings hereunder or under any other Operative Document; (iv) shall not be responsible to the Lender for any action taken or
     omitted to be taken by either of them hereunder or under any other Operative Document or under any other document or instrument
     referred to or provided for herein or therein or in connection herewith or therewith, except for their own gross negligence or
     willful misconduct; and (v) may be removed from its role as Administrative Agent or Collateral Agent (as the case may be) by the
     Lender for cause and upon notice by Lender (or by the Administrative Agent or Collateral Agent on Lender's behalf, as applicable)
     to the Borrower and to the Ratings Agencies.  In the case of any removal of either of the Agents for cause as provided herein,
     the Lender may replace such removed Agent with another entity without obtaining the prior written consent of the Borrower so long
     as such replacement entity is GE Capital or one of its Affiliates.  The Borrower shall be required to give written consent to any
     replacement agent who is not GE Capital or one of its Affiliates, such consent not to be unreasonably withheld.  The Agents may
     employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or
     attorneys-in-fact selected by it in good faith.

(b)      Reliance by Agents.  The Agents shall be entitled to rely upon any certification, notice or other communication (including,
         ------------------
     without limitation, any thereof by telephone, telecopy, telex, telegram or cable) believed by them to be genuine and correct and
     to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel,
     independent accountants and other experts selected by the Agents.  As to any matters not expressly provided for herein or in any
     other Operative Document, the Agents shall in all cases be fully protected in acting, or in refraining from acting, hereunder or
     thereunder in accordance with instructions given by the Lender as is required in such circumstance, and such instructions of such
     Lender and any action taken or failure to act pursuant thereto shall be binding on all of the Lender.

(c)      Defaults.  The Agents shall not be deemed to have knowledge or notice of the occurrence of a Default (other than the
         --------
     non-payment of principal of or interest on Notes) unless the Agents have received notice from the Lender or the Borrower
     specifying such Default and stating that such notice is a "Notice of Default".  In the event that the Agents receive such a
     notice of the occurrence of a Default, the Agents shall give prompt notice thereof to the Lender (and shall give the Lender
     prompt notice of each such non-payment).  The Agents shall (subject to Section 16(a) hereof) take such action with respect to
     such Default as shall be directed by the Lender, provided that, unless and until the Agents shall have received such directions,
                                                      --------
     the Agents may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default
     as they shall deem advisable in the best interest of the Lender except to the extent that this Agreement expressly requires that
     such action be taken, or not be taken, only with the consent or upon the authorization of the Lender.

(d)      Rights as Agent.  PK and GE Capital (and any successor acting as Administrative Agent or Collateral Agent, as the case may
         ---------------
     be) and its affiliates may (without having to account therefor to the Lender) accept deposits from, lend money to, make
     investments in and generally engage in any kind of loan, trust or other business with the Borrower (and any of its subsidiaries
     or Affiliates) as if it were not acting as the Administrative Agent or Collateral Agent (as the case may be), and PK, GE Capital
     and their affiliates may accept fees and other consideration from the Borrower for services in connection with this Agreement or
     otherwise without having to account for the same to the Lender.

(e)      Failure to Act.  Except for action expressly required of the Agents hereunder and under the other Operative Documents, the
         --------------
     Agents shall in all cases be fully justified in failing or refusing to act hereunder and thereunder unless they shall receive
     indemnification against any and all liability and expense that may be incurred by them by reason of taking or continuing to take
     any such action.

(f)      Resignation or Removal of Administrative Agent or Collateral Agent.  Subject to the appointment and acceptance of a
         ------------------------------------------------------------------
     successor Administrative Agent or Collateral Agent as provided below, and subject further to the penultimate sentence of this
     Section 14(f), the Administrative Agent or Collateral Agent may resign at any time by giving notice thereof to the Lender, the
     Borrower and the Ratings Agencies, and the Administrative Agent or Collateral Agent may be removed at any time with cause by the
     Lender.  Upon any such resignation or removal, the Lender shall have the right to appoint a successor Administrative Agent or
     Collateral Agent.  If no successor Administrative Agent or Collateral Agent shall have been so appointed by the Lender and shall
     have accepted such appointment within 30 days after the retiring Administrative Agent's or Collateral Agent's giving of notice of
     resignation or the Lender's removal of the retiring Administrative Agent or Collateral Agent, then the retiring Administrative
     Agent or Collateral Agent may, on behalf of the Lender, appoint a successor Administrative Agent or Collateral Agent.  Upon the
     acceptance of any appointment as Administrative Agent or Collateral Agent hereunder by a successor Administrative Agent or
     Collateral Agent, such successor Administrative Agent or Collateral Agent shall thereupon succeed to and become vested with all
     the rights, powers, privileges and duties of the retiring Administrative Agent or Collateral Agent, and the retiring
     Administrative Agent shall be discharged from its duties and obligations hereunder.  After any retiring Administrative Agent's or
     Collateral Agent's resignation or removal hereunder as Administrative Agent or Collateral Agent, the provisions of this
     Section 14 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was
     acting as the Administrative Agent or Collateral Agent.  Neither Agent shall assign its interest to any replacement agent who is
     not GE Capital or one of its Affiliates without the Borrower's prior written consent, such consent not to be unreasonably
     withheld.

(g)      Consents under Operative Documents.  Except as otherwise provided in Section 16(a) hereof, the Administrative Agent and
         ----------------------------------
     Collateral Agent may, with the prior consent of the Lender (but not otherwise), consent to any modification, supplement or waiver
     under any of the Operative Documents, provided that, without the prior consent of the Lender, neither the Administrative Agent
                                           --------
     nor the Collateral Agent shall (except as provided herein) release any collateral or otherwise terminate any Lien under any
     Operative Document providing for collateral security, or agree to additional obligations being secured by such collateral
     security (unless the Lien for such additional obligations shall be junior to the Lien in favor of the other obligations secured
     by such Operative Document), except that no such consent shall be required, and the Administrative Agent and Collateral Agent are
     each hereby authorized, to release any Lien covering property which is the subject of a disposition of property permitted
     hereunder or to which the Lender has consented.

(h)      Non-Receipt of Funds by the Administrative Agent and Collateral Agent.  Unless the Administrative Agent or Collateral Agent
         ---------------------------------------------------------------------
     shall have been notified by the Lender or the Borrower (the "Payor") prior to the date on which the Payor is to make payment to
                                                                  -----
     the Administrative Agent or Collateral Agent of (in the case of the Lender) the proceeds of a Loan to be made by it hereunder or
     (in the case of the Borrower) a payment to the Administrative Agent or Collateral Agent for account of one or more of the Lender
     hereunder (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that the Payor
                                                      ----------------
     does not intend to make the Required Payment to the Administrative Agent or Collateral Agent, the Administrative Agent or
     Collateral Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be
     required to), make the amount thereof available to the intended recipient(s) on such date and, if the Payor has not in fact made
     the Required Payment to the Administrative Agent or Collateral Agent, the recipient(s) of such payment shall, on demand, repay to
     the Administrative Agent or Collateral Agent (as the case may be) the amount so made available together with interest thereon in
     respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent or
     Collateral Agent (as the case may be) until the date the Administrative Agent or Collateral Agent (as the case may be) recovers
     such amount at a rate per annum equal to the Federal Funds Rate for such day and, if such recipient(s) shall fail promptly to
     make such payment, the Administrative Agent or Collateral Agent (as the case may be) shall be entitled to recover such amount,
     from the Payor, together with interest as aforesaid.

Section 15        Investment Of Funds.  Any moneys held by the Administrative Agent as security hereunder for Borrower's obligations

to invest such moneys) in (a) obligations of, or guaranteed by, the United States Government or agencies thereof, (b) open market
commercial paper of any corporation incorporated under the laws of the United States of America or any State thereof rated at least

organized under the laws of the United States or of any political subdivision thereof having a combined capital and surplus in excess
of $750,000,000 which banks or their holding companies have a rating of A or its equivalent by Moody's or S&amp;P; provided, however,
that the aggregate amount at any one time so invested in certificates of deposit issued by any one bank shall not exceed five percent
(5%) of such bank's capital and surplus, (d) Dollar denominated offshore certificates of deposit issued by, or offshore time deposits
with, any commercial bank described in (c) or any subsidiary thereof, and (e) repurchase agreements with any financial institution
having combined capital and surplus of at least $750,000,000 with any of the obligations described in clauses (a) through (d) as
collateral, none of which investments (but exclusive of any underlying investment that may be subject to a repo) shall have a term to
maturity in excess of 30 days.  There shall be promptly remitted to Borrower or its order (but no more frequently than monthly) any
gain (including interest received) realized as a result of any such investment (net or any, fees, commissions and other expenses, if
any, incurred in connection with such investment) unless a Special Default or an Event of Default shall have occurred and be
continuing.  The Borrower shall be responsible for any net loss realized as a result of any such investment and shall reimburse the

     Agreement or any other Operative Document, except as expressly provided herein or therein.

(b)      This Agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered

     Agreement nor any of the terms hereof may be terminated, amended, supplemented, waived or modified, except by an instrument in
     writing signed by the party or parties thereto.

(iv)     Except as set forth in clause (v) below, any assignment or transfer by the Lender hereunder shall be subject to the
     following conditions:

     except as set forth in subclause (F) below, the transferring Lender shall have first obtained the prior written consent of the
                  Borrower, which written consent shall not be unreasonably withheld;

                                            The transferring Lender shall send the Borrower a written notice of such proposed
                  transfer, setting forth the name and address of the proposed transferee, the amount of the transferring Lender's
                  Notes proposed to be transferred and the proposed date on which such transfer will occur.  The Borrower will then
                  have three (3) Business Days to request such additional information as it may reasonably require regarding such
                  proposed transferee, or, if no such additional information is requested and such proposed transfer satisfies the
                  other requirements of this Section 23(c), the Borrower shall be deemed to have consented to such proposed transfer.
                  In the event that the Borrower requests additional information, it shall have three (3) Business Days from the time
                  such additional information is provided to reject such proposed transfer, failing which, subject to satisfaction of
                  the other requirements of this Section 23(c), the Borrower shall be deemed to have given its consent;

                                            as a result of any assignment or transfer, there shall be no more than five (5) lenders
                  in the aggregate;

                                            except as set forth in subclause (E) below, no such assignment or transfer (including,
                  without limitation and for the avoidance of doubt, any assignment or transfer to a CP Conduit) shall be in an amount
                  less than $10,000,000;

                                            so long as no Event of Default shall have occurred or be continuing, no assignment or
                  transfer shall, at the time of such assignment or transfer, increase the obligations of the Borrower under this
                  Agreement or the Mortgage;

                                            Lender shall not be required to obtain Borrower's prior written consent to transfer all
                  or a portion of its Loan and related rights under the Operative Documents to any of its Program Support Providers or
                  to any entity (including, without limitation and for the avoidance of doubt, any CP Conduit) which is administered
                  by, or is an Affiliate of, GE Capital;

                                            except as otherwise set forth herein, no participant in any Loan assigned or transferred
                  hereunder shall have any rights directly against the Borrower; and

                                            without limiting the generality of the foregoing, the Borrower shall not be liable for
                  any withholding taxes or other increased costs if such costs would arise at the time of such transfer or assignment
                  hereunder.

(v)      Notwithstanding anything herein or in any of the other Operative Documents to the contrary, the Lender may, at any time
     after the Delivery Date with respect to any Loan, upon written notice to Borrower but without the consent of Borrower, and
     without any further action or deliveries under the Operative Documents, assign or otherwise transfer all or any part of its
     right, title and interest in and to such Loan and this Agreement (to the extent related to such Loan) to (i) any Program Support
     Provider for any CP Conduit, (ii) to GE Capital or any of its Affiliates or (iii) any CP Conduit administered by GE Capital or
     any of its Affiliates (each, a "Permitted Transferee").  The assigning Lender or the Administrative Agent shall provide the
                                     --------------------
     Borrower prompt notice of such assignment (but failure to provide such notice shall not affect the validity of any such
     assignment).  The Lender may also pledge, mortgage or grant a security interest in this Agreement or the Mortgaged Estate, and
     assign this Agreement and any collateral, as collateral for the Lender's obligations under its Commercial Paper program.  Each
     such Permitted Transferee shall have any and all rights as may be assigned by the Lender to such party but none of the
     obligations of the Lender hereunder or under any other Operative Document.  Upon the written request of the Lender,  Borrower
     agrees to confirm in writing receipt of notice of assignment and to acknowledge its obligations to such Permitted Transferee; and
     fully shall cooperate with the Lender and at Lender's expense, to minimize or avoid the imposition of any adverse tax consequence
     in connection with any such conveyance, transfer, pledge, mortgage, grant of security interest or assignment.

                  In the event the Lender, in accordance with this Section 23(c), assigns its interest in any Loan, together with its
interest herein and in  the other Operative Documents, in each case to the extent relating to such Loan, then all references to "the
Lender" hereunder shall mean and refer to such assignee to the extent of such assignment, and any subsequent assignment by such
assignee shall have a corresponding effect.

                  Subject always to the foregoing, this Agreement inures to the benefit of, and is binding upon, the successors and
assigns of the parties hereto.

(vi)     Notwithstanding the foregoing, the Administrative Agent may not assign or transfer its rights or obligations hereunder or
     under the other Operative Documents without the prior written consent of the Lender, such consent not to be unreasonably withheld.

(vii)    All costs and expenses in connection with any assignment or transfer permitted by this Section 23(c) (including any legal
     fees of counsel to the parties to the Operative Documents) shall be borne by the relevant transferring/assigning lender, except
     in the case of an assignment or transfer that is effected at the request of the Borrower or if an Event of Default shall have
     occurred and be continuing, in which case such costs and expenses (including reasonable legal fees) shall be borne by the
     Borrower.

(d)      Limited Recourse.  The obligations, if any, of the Lender under this Agreement and all other Operative Documents are solely
         ----------------
     the obligations of the Lender.  No recourse shall be had for the making of any Loan under this Agreement or for any other
     obligation or claim arising out of or based upon this Agreement or any other Operative Document against any incorporator,
     shareholder, officer, manager, member or director, past, present or future, of the Lender or of any successor or of the Lender's
     constituent members or other affiliates or of J H Management Corporation, or against J H Management Corporation, either directly
     or through the Lender or any successor, whether by virtue of any constitution, statute or rule of law or by the enforcement of
     any assessment or penalty or otherwise, all such liability being, by acceptance thereof and as part of the consideration for the
     acceptance hereof, expressly waived and released.  Nothing in this Section 23(d) shall be deemed to impair or otherwise diminish
     any obligation of the Administration Agent or the Collateral Agent under this Agreement or the other Operative Documents.  The
     provisions of this Section 23(d) shall survive the termination of this Agreement.

                  Notwithstanding any provisions contained in this Agreement to the contrary, the Lender shall not, and shall not be
obligated to, pay any amount pursuant to this Agreement unless (i) the Lender has  received funds which may be used to make such
payment pursuant to the documents governing its Commercial Paper program, and (ii) after giving effect to such payment, either (A)
the Lender could issue Commercial Paper (assuming such outstanding Commercial Paper matured at such time) without violating any of
the provisions of the documents governing its Commercial Paper program, or (B) all Commercial Paper is paid in full.  Any amount
which the Lender does not pay pursuant to the operation of the preceding sentence shall not constitute a Claim (as defined inss.101 of
the Bankruptcy Code) against or an obligation of the Lender for any insufficiency unless and until the Lender satisfies the
provisions of such preceding sentence.

(e)      The Lender shall not have any obligation or duty to the Borrower, or to other Persons with respect to the transactions
     contemplated hereby except those obligations or duties of the Lender expressly set forth in this Agreement and the other
     Operative Documents and the Lender shall not be liable for performance by any other party hereto of such other party's
     obligations or duties hereunder.  Without limitation of the generality of the foregoing, under no circumstances whatsoever shall
     the Lender be liable to the Borrower for any action or inaction on the part of the Administrative Agent or the Collateral Agent
     in connection with the transactions contemplated herein, whether or not such action or inaction is caused by willful misconduct
     or gross negligence of the Administrative Agent or the Collateral Agent, as applicable.

                                                             Schedule III

                                                      Determination of Base Rate
                                                      --------------------------

                  In respect of each Loan, two Business Days before the Delivery Date of the applicable  Aircraft,  the  Administrative
Agent (at the  direction  of the  Lender)  shall  solicit  quotations  for the "fixed  rate" of  interest  in respect of the Swap.  The
Administrative  Agent (at the direction of the Lender) agrees to cooperate  with the Borrower in the  solicitation  of such  quotations
and the timing  thereof  with the intent of  obtaining  the lowest  "fixed  rate." The  Administrative  Agent (at the  direction of the
Lender) will  communicate  the results of its  solicitation  and the quoted "fixed rate" obtained  thereby (the  "Administrative  Agent
Quoted Rate") to the  Borrower.  The Borrower may, as soon  thereafter as  practicable,  but no later than on the Business Day that the
Administrative  Agent  Quoted  Rate is  communicated  to it,  accept or reject the  Administrative  Agent  Quoted  Rate and may solicit
additional  quotations  for the "fixed  rate" of interest in respect of the Swap.  If the  Borrower  accepts the  Administrative  Agent
Quoted Rate, the  Administrative  Agent Quoted Rate shall be the rate used in  determining  the Base Rate.  If,  however,  the Borrower
obtains a quotation  from a  counterparty  for a "fixed  rate" of interest in respect of a Swap (which  fixed rate which shall be based
upon the Swap Agreement  deemed to be entered into between such  counterparty  and the  Administrative  Agent, is herein referred to as
the  "Borrower  Rate")  which is lower  than the  Administrative  Agent  Quoted  Rate for the  Swap,  the  Borrower  shall  notify  the
Administrative  Agent of the Borrower Rate for that Swap and the counterparty  providing the quote. If such  counterparty is reasonably
acceptable to the  Administrative  Agent,  (at the direction of the Lender) taking into account its credit  assessment  of,  historical
experience  with and credit and country  risk  limitations  for,  that  counterparty,  and the  counterparty,  if so  requested  by the
Administrative  Agent (at the direction of the Lender),  confirms its ability and  willingness  to enter into a Swap, the Borrower Rate
shall be the rate used in  determining  the Base Rate.  Nothing set forth herein shall require the  Administrative  Agent or any Lender
to actually enter into the Swap, but if neither the Administrative  Agent nor any Lender enters into a Swap, the  Administrative  Agent
and the  Lenders  shall be deemed  to have  entered  into the Swap at the  Administrative  Agent  Quoted  Rate or (if the  counterparty
provided by the Borrower was  acceptable  to the  Administrative  Agent) the Borrower  Rate.  The Borrower may elect to forward fix the
Applicable Rate with respect to any Aircraft,  with the prior written consent of the Administrative  Agent, up to thirty (30)  calendar
days prior to the Delivery Date for such Aircraft,  in which case the  Administrative  Agent (on behalf of the Lender) may be deemed to
enter into the Swap upon two (2) Business Days' notice of the date Borrower intends to fix the Applicable Rate (the "Fixing Date").
                                                                                                                     -----------

                                                              Schedule IV

                                                 Determination of Swap Breakage Amount
                                                 -------------------------------------

                  A.       Swap Breakage Amount,  as of any date, shall be the amount determined in good faith by the swap counterparty
and notified to the  Administrative  Agent as the amount  required to be paid to the swap  counterparty  (or deemed swap  counterparty)
under such Swap ("Swap Breakage Loss") or the amount  receivable from (and, in the case of a true third party swap,  actually  received
from) the swap  counterparty (or deemed swap  counterparty)  under such Swap ("Swap Breakage Gain"),  in either case, to settle out for
such Swap, in accordance with market practice, as of 12:00 noon, New York time, on such date (the "Settlement Date").

                  B.       On the Settlement  Date,  Borrower may designate a Reference  Market-maker (as defined in the Swap Agreement
with the "party" referred to in such definition  being the swap  counterparty) to the  Administrative  Agent and the swap  counterparty
(which Reference  Market-maker  shall be reasonably  acceptable to the swap  counterparty)  and request such Reference  Market-maker to
advise the  Borrower,  the  Administrative  Agent and the swap  counterparty  by  12:00 noon,  New York time,  on such date of the Swap
Breakage  Loss,  or the Swap  Breakage  Gain,  in either case, to assume the  obligations  of the  Administrative  Agent under the Swap
Agreement  with  respect  to the Swap but only with  respect  to the then  outstanding  principal  amount  of the Note.  In the event a
payment is to be made to the  Administrative  Agent in  consideration of the aforesaid  termination or assumption,  as the case may be,
the  greater of the amounts to be so paid (or if each of the swap  counterparty  and the  Reference  Market-maker  quote the  identical
amount, or if the Reference  Market-maker fails to quote or, having quoted,  defaults in its agreement to assume (or otherwise fails to
assume)  the  aforesaid  obligations  of the  Administrative  Agent,  the amount  quoted by the swap  counterparty)  shall be the "Swap
Breakage  Amount"  (expressed as a negative number) for all purposes of the Operative  Documents.  In the event a payment is to be made
by the  Administrative  Agent in  consideration  of the  aforesaid  termination  or  assumption,  as the case may be, the lesser of the
amounts to be so paid (or if each of the swap  counterparty  and the  Reference  Market-maker  quote the  identical  amount,  or if the
Reference  Market-maker  fails to quote or,  having  quoted,  defaults in its  agreement to assume (or  otherwise  fails to assume) the
aforesaid  obligations of the Lender, the amount quoted by the swap  counterparty)  shall be the "Swap Breakage Amount" (expressed as a
positive number) for all purposes of the Operative Agreements.

                  C.       The Administrative  Agent agrees that, except as provided above, it will not amend or terminate or permit to
be  terminated  through its own action or  inaction  the Swap in a manner  that would have a material  adverse  effect on the rights or
interests of Borrower  without the prior written consent of Borrower (such consent not to be unreasonably  withheld);  provided that if
the swap  counterparty  shall default in  performance  of its  obligations in respect of the Swap or under the Swap Agreement or if the
Swap Agreement shall otherwise terminate (other than as a result of the breach by Administrative  Agent of any of its  representations,
warranties or obligations  thereunder),  the  Administrative  Agent may enter into swap  transactions with another swap counterparty on
terms  substantially  similar to those entered into as of the Delivery Date (so long as such transactions does not materially  increase
the  economic  exposure of Borrower  with respect to any payment of Swap  Breakage  Amount which may  thereafter  be or become  payable
hereunder or under the other  Operative  Documents)  and after such time,  the "swap  transaction"  and the swap  counterparty  for the
Administrative Agent shall be such transaction and such counterparty for all purposes of the Operative Documents.

                  D.       The  Administrative  Agent agrees that,  upon notice from Borrower of the  possibility of the occurrence of:
(i) the prepayment of a Loan pursuant to Section 10(f) of the Credit Agreement,  (ii) the  prepayment of a Loan following  acceleration
pursuant to  Section 12(a)  of the Credit  Agreement or (iii) the  prepayment  of purchase of a Loan pursuant to  Section 10(h)  of the
Credit Agreement,  the  Administrative  Agent shall promptly  thereafter provide Borrower with a non-binding good faith estimate of the
Break Funding Amount.  Further,  the  Administrative  Agent will use its reasonable efforts to cause the swap counterparty to cooperate
with Borrower with respect to the  provisions  hereof and to provide in a timely  fashion such  information  as Borrower may reasonably
request to facilitate the quotation and assumption by the Reference Market-maker contemplated in paragraph B above.

                                                                                                       [Credit Agreement [Frontier/PK]]

purposes  whether or not this Note is overdue,  and neither the  Borrower nor the  Administrative  Agent shall be affected by notice to
the contrary.

acceleration by the  Administrative  Agent as provided in Section 12(a) of the Credit  Agreement,  and the Lender, by its acceptance of

                  ----------------------------
Aircraft to be duly registered in its name (if not so registered) and, at all times thereafter, to remain duly registered in the
United States of America in its name under the Federal Aviation Act and (b) on the Delivery Date for each Aircraft, cause this
Mortgage to be duly recorded in the name of the Collateral Agent for the benefit of the Lender and, at all times thereafter, so long
as any Note shall be outstanding or any amount shall be owing to the Lender (but subject to Section 15.01(b)), cause this Mortgage to
be so maintained of record as a first priority and perfected mortgage on the Aircraft; (2) maintain, service, repair, and overhaul
(or cause to be maintained, serviced, repaired, and overhauled) each Aircraft (and any engine which is not an Engine but which is
installed on an Aircraft) (a) so as to keep such Aircraft in as good condition as when delivered to the Borrower by the Manufacturer
(ordinary wear and tear excepted) and so as to keep such Aircraft in good operating condition and in such condition as may be
necessary to enable the airworthiness certification for such Aircraft to be maintained in good standing at all times under the
Federal Aviation Act except when (i) such Aircraft is being serviced, repaired, maintained, overhauled, tested or modified as
permitted or required by the terms of this Mortgage or (ii) all Airbus A319-111 aircraft of comparable vintage and/or configuration

Section 3.02      Operation.  The Borrower will not maintain, use, service, repair, overhaul or operate the Aircraft in violation of
                  ---------
any law, rule, regulation, treaty, or order of any government or governmental authority (domestic or foreign) having jurisdiction, or
in violation of any airworthiness certificate, license or registration relating to the Aircraft issued by any such authority except
the Borrower may contest in good faith the validity or application of any such law, rule, regulation, treaty, order, certificate,
license or registration, so long as there is no material risk of the sale, forfeiture or loss of any Aircraft, any Airframe or any
Engine, or the Collateral Agent's interest therein.  The Borrower will not operate or fly any Aircraft in or to any war zone or any
area of threatened or recognized hostility or in any area excluded from coverage by any insurance required to be maintained by the
terms of Article VI (or any indemnity issued in lieu thereof); provided, however, that the failure of the Borrower to comply with the
provisions of this sentence shall not give rise to an Event of Default hereunder where such failure is an extraordinary occurrence
attributable to a hijacking, medical emergency, equipment malfunction, weather condition, navigational error or similar event.

Section 3.03      Possession and Leases.  The Borrower will not, without the prior written consent of the Administrative Agent at the
                  ---------------------
direction of the Lender, which consent (and direction) will not be unreasonably withheld or delayed, lease or otherwise in any manner
deliver, transfer or relinquish possession of any Airframe or any Engine or install or permit any Engine to be installed on any
airframe other than an Airframe; provided that so long as no Event of Default shall have occurred and be continuing at the time of
such delivery, transfer or relinquishment of possession or installation and the Borrower shall continue to comply with the provisions
of Section 3.01 and Article VI, the Borrower may, without the prior written consent of the Administrative Agent:

(a)      subject any Engine to normal pooling or similar arrangements customary in the airline industry and entered into by the
Borrower in the ordinary course of its business with a U.S. Air Carrier or any other air carrier approved in writing by the
Administrative Agent at the direction of the Lender (which approval will not be unreasonably withheld or delayed); provided that
(i) no such agreement or arrangement contemplates or requires the transfer of title to any Engine and (ii) if the Borrower's title to
any Engine shall be divested under any such agreement or arrangement, such divestiture shall be deemed to be an Event of Loss with
respect to such Engine and the Borrower shall comply with Section 5.02 hereof in respect thereof;

(b)      deliver possession of any Airframe or any Engine to the Manufacturer or the Engine Manufacturer, or to any Person for
testing, service, repair, maintenance or overhaul work on any Airframe or any Engine or for alterations or modifications in or
additions to the Airframe(s) or Engine(s);

(c)      install an Engine on an airframe owned by the Borrower, leased to the Borrower, or owned or purchased by the Borrower
subject to a conditional sale or other security agreement, provided that (a) such airframe is free and clear of all Liens, except
(i) in the case of airframes leased to the Borrower or owned or purchased by the Borrower subject to a conditional sale or other
security agreement, the rights of the parties to the lease or conditional sale agreement or other security agreement covering such
airframe, or their assignee, (ii) Permitted Liens, and (iii) the rights of other air carriers under normal interchange agreements
which are customary in the airline industry and do not contemplate, permit or require the transfer of title to the airframe or
engines installed thereon, and (b) any such lease, conditional sale or other security agreement provides that such Engine shall not
become subject to the lien of such lease, conditional sale or other security agreement, notwithstanding the installation thereof on
such airframe, and the inclusion in such agreement of a provision similar to the last paragraph of this Section 3.03 shall satisfy
such requirement;

(d)      install an Engine on an airframe owned by the Borrower, leased to the Borrower or purchased by the Borrower subject to a
conditional sale or other security agreement under circumstances where paragraph 3.03(c) above is inapplicable, provided that such
installation shall be deemed an Event of Loss with respect to such Engine and the Borrower shall comply with Section 5.02 hereof in
respect thereof, the Administrative Agent not intending hereby to waive any right or interest it may have to or in such Engine under
applicable law until compliance by the Borrower with such Section 5.02;

(e)      transfer possession of any Airframe or any Engine to the United States of America or any instrumentality or agency thereof
pursuant to CRAF so long as the Borrower shall promptly notify the Administrative Agent upon transferring possession of such Airframe
or any Engine to the United States of America or any agency or instrumentality thereof pursuant to such program and provide the
Administrative Agent with the name and address of the Contracting Office Representative for the Military Aircraft Command of the
United States Air Force to whom notice must be given in the event the Administrative Agent desires to give notice as provided in
Section 12 of the Credit Agreement;

(f)      transfer possession of any Airframe or any Engine to the United States of America or any instrumentality or agency thereof
which bears the full faith and credit of the United States of America; and

(g)      enter into a lease with (i) any U.S. Air Carrier approved in writing by the Administrative Agent at the direction of the
Lender, which approval (or direction) shall not be unreasonably withheld, and which is authorized by an applicable Governmental
Authority to conduct commercial airline operations and to operate A319-100 aircraft, or (ii) any other Person approved in writing by
the Administrative Agent at the direction of Lender.

         The rights of any transferee who receives possession by reason of a transfer permitted by this Section 3.03 (other than the
transfer of an Engine deemed an Event of Loss) shall be subject and subordinate to (and, in the case of any lease, shall be expressly
subject and subordinate to) all the terms of this Mortgage; provided that in the case of the use of an Aircraft in CRAF the subject
and subordinate requirements herein shall be subject to the notice specified in Section 12 of the Credit Agreement and other
requirements of the CRAF program.  In the case of any lease, the Borrower shall remain primarily liable hereunder for the performance
of all of the terms of this Mortgage, and the terms of any such lease shall not permit any lessee to take any action not permitted to
be taken by the Borrower hereunder with respect to the Aircraft and may permit the Borrower to cure any default by the lessee and to
terminate the lease upon such default.

         Any Wet Lease or similar arrangement under which the Borrower maintains operational control of an Aircraft shall not
constitute a delivery, transfer or relinquishment of possession for purposes of this Section 3.03 so long as such Wet Lease shall be
for a term (including any renewals) not in excess of three months and is wet leased to a U.S. Air Carrier.

         The Collateral Agent agrees, for the benefit of the Borrower, and for the benefit of any mortgagee or other Lender of a
security interest in any engine owned by the Borrower, any lessor of any engine leased to the Borrower and any conditional vendor of
any engine purchased by the Borrower subject to a conditional sale agreement or any other security agreement, that no interest shall
be created hereunder in any engine so owned, leased or purchased and that neither the Collateral Agent nor its successors or assigns
will acquire or claim, as against the Borrower or any such mortgagee, lessor or conditional vendor or other Lender of a security
interest or interest in such engine as the result of such engine being installed on an Airframe; provided, however, that such
agreement of the Collateral Agent shall not be for the benefit of any lessor or secured party of any airframe leased to the Borrower
or purchased by the Borrower subject to a conditional sale or other security agreement or for the benefit of any mortgagee of or any
other Lender of a security interest in an airframe owned by the Borrower, unless such lessor, conditional vendor, other secured party
or mortgagee has agreed (which agreement may be contained in such lease, conditional sale or other security agreement or mortgage and
may consist of a paragraph similar to this paragraph) that neither it nor its successors or assigns will acquire, as against the
Collateral Agent, any right, title or interest in an Engine as a result of such Engine being installed on such airframe.

Section 3.04      Insignia.  On or prior to the Delivery Date, or as soon thereafter as practicable, the Borrower agrees to affix and
                  --------
maintain (or cause to be affixed and maintained) in the cockpit of each Airframe and on each Engine a nameplate bearing the
inscription:

                  Mortgaged To

                  General Electric Capital Corporation, as Collateral Agent

(such nameplate to be replaced, if necessary, with a nameplate reflecting the name of any successor to the Collateral Agent as
permitted under the Operative Documents).

         Nothing herein contained shall prohibit the Borrower from placing its customary colors and insignia on each Airframe or any
Engine or from otherwise operating the Aircraft in its livery.

installed as provided in Section 4.02) shall be free and clear of all Liens (except Permitted Liens), and shall be in as good an
operating condition, and shall have a value and utility substantially equal to, the Parts replaced, assuming such replaced Parts were
in the condition and repair required to be maintained by the terms hereof.  All Parts at any time removed from any Airframe or any
Engine shall remain subject to the Lien of this Mortgage, no matter where located, until such time as such Parts shall be replaced by
parts which meet the requirements for replacement parts specified above.  Upon any replacement part becoming incorporated or
installed in or attached to any Airframe or any Engine, without further act (subject only to Permitted Liens and any arrangement
permitted by Section 4.02 hereof), (i) such replacement part shall become subject to the Lien of this Mortgage and be deemed a Part
for all purposes hereof to the same extent as the Parts originally incorporated or installed in or attached to such Airframe or such
Engine and (ii) the replaced Part shall no longer be deemed a Part hereunder.

Section 4.02      Pooling of Parts; Temporary Replacement Parts.  Any Part removed from any Airframe or any Engine as provided in
                  ---------------------------------------------
Section 4.01 hereof may be subjected by the Borrower to a pooling arrangement of the type which is permitted for Engines by
Section 3.03(a) hereof; provided that the Part replacing such removed Part shall be incorporated or installed in or attached to such
Airframe or Engine in accordance with Section 4.01 as promptly as practicable after the removal of such removed Part.  In addition,
the Borrower may use temporary parts or pooled parts on an Aircraft as temporary replacements for Parts, provided that the Borrower
as promptly thereafter as practicable, either (1) causes such pooled or temporary replacement part to become subject to the Lien of
this Mortgage free and clear of all Liens other than Permitted Liens or (2) replaces such replacement part with a further replacement
part owned by the Borrower which meets the requirements of Section 4.01 and which shall become subject to the Lien of this Mortgage,
free and clear of all Liens other than Permitted Liens.

Section 4.03      Alterations, Modifications and Additions.  The Borrower will make (or cause to be made) such alterations,
                  ----------------------------------------
modifications and additions to the Airframes and Engines as may be required to meet the applicable standards of the FAA, subject to
clauses (2)(a)(i) and (ii) of Section 3.01.  In addition, the Borrower may from time to time make such alterations and modifications
in and additions to any Airframe or any Engine as the Borrower may deem desirable in the proper conduct of its business, including
removal of Parts which the Borrower deems to be obsolete or no longer suitable or appropriate for use on such Airframe or such
Engine; provided that no such alteration, modification, removal or addition impairs the condition or airworthiness of such Airframe
or such Engine, or diminishes the value, utility and remaining useful life of such Airframe or such Engine below the value, utility
or remaining useful life thereof immediately prior to such alteration, modification, removal or addition, assuming that such Airframe
or such Engine is in the condition required hereunder.  All parts incorporated or installed in or attached or added to an Airframe or
an Engine as the result of such alteration, modification or addition (except those parts which the Borrower has leased from others
and Parts which may be removed by the Borrower pursuant to the next sentence) (the "Additional Part" or "Additional Parts") shall,
                                                                                    ---------------      ----------------
without further act, become subject to the Lien of this Mortgage.  Notwithstanding the foregoing, the Borrower may remove any
Additional Part, provided that such Additional Part (i) is in addition to, and not in replacement of or substitution for, any Part
originally incorporated or installed in or attached to any Airframe or any Engine at the time of delivery thereof hereunder or any
Part in replacement of or substitution for any such Part, (ii) is not required to be incorporated or installed in or attached or
added to any Airframe or any Engine pursuant to the terms of Article III hereof or the first sentence of this Section 4.03, and
(iii) can be removed from such Airframe or such Engine without impairing the airworthiness of such Airframe or such Engine or
diminishing the value, utility and remaining useful life of such Airframe or such Engine which such Airframe or such Engine would
have had at such time had such alteration, modification or addition not occurred.  Upon the removal thereof as provided above, such
Additional Parts shall be deemed free of Lien of this Mortgage.

Section 4.04      Improvements Owned by Others.  Notwithstanding any other provision of this Mortgage, the Borrower may install or
                  ----------------------------
permit to be installed in an Aircraft audio-visual, entertainment, telephonic or other equipment owned by third parties (or owned
jointly by the Borrower and others) and leased or otherwise furnished to the Borrower in the ordinary course of business, provided
that such equipment meets all requirements for removal of Additional Parts as specified in Section 4.03, and the Lien of this
Mortgage shall not attach thereto and the rights of the owners therein shall not constitute a default under the Operative Documents.

Section 4.05      Substitution of Engines.  So long as no Default or Event of Default shall have occurred and be continuing, Borrower
                  -----------------------
shall have the right at its option at any time on at least five Business Days' prior written notice, to terminate the Lien of this
Mortgage with respect to any Engine.  In such event, and at the time of such termination, the Borrower shall replace such Engine
hereunder by complying with the terms of Section 5.02 hereof to the same extent as if an Event of Loss had occurred with respect to
such Engine (other than the time periods allowed for such replacement), and the Collateral Agent (at the direction of the Lender or
the Administrative Agent on its behalf) shall release the replaced Engine from the Lien of this Mortgage as provided in Section 5.02.

Article V

Collateral Agent and the Lender written notice of such Event of Loss but in any event within five days of such occurrence.  On the
earlier of (x) the 90th day following the occurrence of such Event of Loss or (y) the fifth Business Day following the receipt of the
insurance proceeds in respect of such Event of Loss, the Borrower shall pay or cause to be paid to the Administrative Agent an amount
equal to the aggregate amount of the payment or payments of principal, Break Amount and Swap Breakage Amount (if any), Additional
Costs, interest and other amounts then due on or in respect of the Notes of the Series issued with respect to such Airframe and all
other amounts due under the Operative Documents.

Section 5.02      Event of Loss With Respect to an Engine.  Upon the occurrence of an Event of Loss with respect to an Engine under
                  ---------------------------------------
circumstances in which there has not occurred an Event of Loss with respect to an Airframe, the Borrower shall forthwith give the
Administrative Agent, the Collateral Agent and the Lender written notice thereof (but in any event within ten days of such
occurrence) and shall, within 60 days after the occurrence of such Event of Loss (or, in the case of an Event of Loss described in
clause (vi) of the definition thereof, within 90 days after the Chief Financial Officer, Treasurer, any Vice President or other
officer of the Borrower elected by the Borrower's Board of Directors has received actual knowledge of such Event of Loss), as
replacement for the Engine with respect to which such Event of Loss occurred, subject to the Lien of this Mortgage another CFM
International, Inc. Model CFM56-5B5/P engine (or an engine of the same manufacturer of an equivalent or an improved model and
suitable for installation and use on the Airframes and compatible with the other Engines mortgaged hereunder) free and clear of all
Liens (other than Inchoate Liens) and having a value and utility at least equal to, and being in as good an operating condition, as
the Engine subject to such Event of Loss, assuming such Engine was maintained in accordance with the provisions of this Mortgage.
Prior to or at the time of any such conveyance, the Borrower will (i) cause a Mortgage Supplement with respect to such Replacement
Engine to be duly executed and filed for recording pursuant to the Federal Aviation Act, (ii) furnish the Administrative Agent and
Collateral Agent with an opinion of the Borrower's counsel to the effect that such Replacement Engine is owned by Borrower free and
clear of all Liens (other than Inchoate Liens), and that upon execution and filing of the Mortgage Supplement or other required
document the Replacement Engine will be subject to the Lien of the Mortgage on a first priority and perfected basis; provided that,
in the case of any such Lien which ranks on par with or ahead in priority to the Lien of the Mortgage, the Borrower may satisfy the
foregoing requirement if the Borrower shall have provided a bond or other security in respect of such Lien in an amount and under
terms reasonably satisfactory to the Administrative Agent at the direction of the Lender, (iii) furnish a certificate signed by a
duly authorized officer of the Borrower stating with respect to any Replacement Engine:  (1) a description of the Engine suffering
the Event of Loss, which shall be identified by manufacturer's serial number; (2) a description of the Replacement Engine (including
the manufacturer's name and serial number); (3) that on the date of the Mortgage Supplement relating to the Replacement Engine the
Borrower will be the owner of such Replacement Engine free and clear of all Liens except Permitted Liens, that such Replacement
Engine will be on such date in good working order (subject to maintenance permitted or required by this Mortgage) and condition and
that such Replacement Engine is of the same or an improved model of the Engine; and (4) that each of the conditions specified in this
Section 5.02 and Section 10.01 with respect to such Replacement Engine has been satisfied and (iv) furnish the Administrative Agent
and the Collateral Agent with such evidence of compliance with the insurance provisions of Article VI hereof with respect to such
Replacement Engine as the Administrative Agent or the Collateral Agent may reasonably request.  Upon compliance by the Borrower with
all of the terms of this Section 5.02 and Section 13(a) of the Credit Agreement such Engine shall thereupon cease to be an Engine
secured hereunder.  For all purposes hereof, each such Replacement Engine shall, after such conveyance, be deemed an "Engine"
hereunder.

Agent from any governmental authority or other Person with respect to an Event of Loss (other than a requisition for use by the
government of the United States of America not constituting an Event of Loss) will be applied as follows:

                  1.       If  payments  are  received  with  respect to an Airframe  (or an  Airframe  or any Engines or engines  then
installed  thereon),  after  reimbursement  of the  Administrative  Agent,  Collateral  Agent and the Lender for  reasonable  costs and
expenses,  so much of such  payments  remaining  as shall not  exceed the  amounts  required  to be paid by the  Borrower  pursuant  to
Section 5.01  shall be paid to the  Administrative  Agent and  applied in  reduction  of the  Borrower's  obligation  to pay such other
amounts, if not already paid by the Borrower,  or, if already paid by the Borrower,  shall be applied to reimburse the Borrower for its
payment of such  amounts,  and  following  the  foregoing  application,  the  balance,  if any, of such  payments  shall be paid to the
Borrower; and

                  2.       If such payments are received with respect to an Engine under  circumstances  contemplated  by  Section 5.02
hereof,  so much of such payments  remaining after  reimbursement  of the  Administrative  Agent,  Collateral  Agent and the Lender for
reasonable  costs and  expenses  shall be paid over to, or retained  by, the  Borrower,  provided  that the  Borrower  shall have fully

Collateral Agent of such requisition or activation, and all of the Borrower's obligations under this Mortgage with respect to such
Aircraft shall continue to the same extent as if such requisition or activation had not occurred.  All payments received by the
Administrative Agent, Collateral Agent or the Borrower from such government for the use of such Airframe and Engines or engines shall

declares this Mortgage to be in default pursuant to Section 12 of the Credit Agreement, applied against the Borrower's obligations
hereunder as and when due.  At such time as there shall not be continuing any such Special Default or Event of Default, such amount

(a)      Except as provided in paragraph (b) of this Section 6.01, and subject to the self insurance to the extent permitted by
Section 6.04 and the provisions of Section 6.08, the Borrower will at all times carry and maintain or cause to be carried and

passenger legal liability, bodily injury liability, war risk and allied perils liability, property damage liability, and contractual
liability (exclusive of manufacturer's product liability insurance) with respect to each Aircraft in an amount per occurrence not
less than $500,000,000.  The Borrower shall maintain cargo liability insurance in an amount not less than the amount of cargo
liability insurance maintained for other aircraft operated by the Borrower.

(b)      During any period that an Aircraft is on the ground and not in operation, the Borrower may carry or cause to be carried, in
lieu of the insurance required by paragraph (a) above, and subject to the self-insurance to the extent permitted by Section 6.04,
insurance otherwise conforming to the provisions of said paragraph (a) except that (i) the amounts of coverage shall not be required
to exceed the amounts of bodily injury liability and property damage liability insurance from time to time applicable to aircraft
owned or leased by major U.S. carriers of the same or similar type as such Aircraft which are on the ground and not in operation and
(ii) the scope of the risks covered and the type of insurance shall be consistent with industry practice and the same as from time to
time shall be applicable to aircraft owned or leased by major U.S. carriers of the same or similar type which are on the ground and
not in operation and will be consistent with industry practice.

Section 6.02      Insurance Against Loss or Damage to the Aircraft.
                  ------------------------------------------------

(a)      Except as provided in paragraph (b) of this Section 6.02 and the provisions of Section 6.08, and subject to the provisions
of Section 6.04 permitting self-insurance, the Borrower shall at all times carry and maintain or cause to be carried and maintained,

Aircraft (providing insurance for replacement value), and (iii) war risk and allied perils insurance, including governmental
confiscation and expropriation (other than by the government of registry of an Aircraft) and hijacking insurance (collectively, "War
                                                                                                                                 ----
Risk Insurance"); provided that, in the case of War Risk Insurance, such insurance shall only be required to be maintained (x) with
--------------
respect to the buy-backs covering strikes, sabotage, confiscation and hijacking contained in London Form LSW 555B and (y) with
respect to terms and provisions of War Risk Insurance in addition to those covered by the preceding clause (x), (A) if and to the
extent the same is maintained by the Borrower with respect to other aircraft owned or operated by the Borrower on the same routes or
(B) if an Aircraft is operated in a war zone (unless the Borrower obtains indemnification in lieu thereof pursuant to Section 6.06
hereof) or (C) if and to the extent the same is industry standard for major U.S. carriers operating similarly-sized aircraft on
similar routes; provided, further, that the foregoing insurance shall at all times while an Aircraft is subject to this Mortgage be
for an amount (taking into account self-insurance to the extent permitted by Section 6.04) not less than the Stipulated Insured
Amount.  In the case of a loss with respect to an engine (other than an Engine) installed on an Airframe, the Administrative Agent
shall hold any payment received by it of any hull insurance proceeds in respect of such loss for account of the Borrower or any other
third party to the extent the Borrower or such third party is entitled to receive such proceeds.

         Except during a period when a Special Default or an Event of Default has occurred and is continuing (in which case all
losses will be adjusted by the loss payee), all losses will be adjusted with the insurers by the Borrower (giving due regard to the
interest of the Collateral Agent and Administrative Agent).  It is agreed that all insurance payments received under insurance
policies required to be maintained by the Borrower pursuant to this Section 6.02 as the result of the occurrence of an Event of Loss
will be applied as follows:

                  1.       if such  payments are  received  with  respect to an Airframe  (or such  Airframe and the Engines  installed
thereon),  payments as shall not exceed the amounts due  pursuant to  Section 10(f)  of the Credit  Agreement  shall be applied,  after
reimbursement  of the  Administrative  Agent for reasonable costs and expenses,  in reduction of the Borrower's  obligation to pay such
amounts, if not already paid by the Borrower,  or, if already paid by the Borrower,  shall be applied to reimburse the Borrower for its
payment of such  amounts and the  balance,  if any, of such  payments  remaining  thereafter  will be paid over to, or retained by, the
Borrower; and

                  2.       if  such  payments  are  received  with  respect  to an  Engine  under  the  circumstances  contemplated  by
Section 5.02  hereof,  such payments  shall be paid over to, or retained by, the Borrower,  provided that the Borrower shall have fully
performed or,  concurrently  therewith,  will fully perform the terms of Section 5.02  with respect to the Event of Loss for which such
payments are made.

         The insurance payments for any property damage loss to any Airframe or any Engine not constituting an Event of Loss with
respect thereto or with respect to an Event of Loss of an Engine shall be paid as follows:  all payments in respect of losses less
than or equal to $750,000 shall be paid to the Borrower, and all payments with respect to losses greater than $750,000 shall be paid
to the Administrative Agent, to be held as collateral security for the Borrower's obligations hereunder, and applied to reimburse the
Borrower for accomplishing repairs and/or replacements as required, or to pay suppliers directly for such repairs and/or replacements
as directed by the Borrower.  In the case of any payment to the Administrative Agent (other than in respect of an Event of Loss of an
Aircraft), the Administrative Agent shall, upon receipt of evidence reasonably satisfactory to it that the damage giving rise to such
payment shall have been repaired or that such payment shall then be required to pay for repairs then being made or the replacement of
the Engine suffering the Event of Loss, pay the amount of such payment, and any interest or income earned thereon, to the Borrower or
its order.

(b)      During any period that an Aircraft is on the ground and not in operation, the Borrower may carry or cause to be carried, in
lieu of the insurance required by paragraph (a) above, and subject to the self-insurance to the extent permitted by Section 6.04,
insurance otherwise conforming with the provisions of said paragraph (a), except that the scope of the risks and the type of
insurance shall be the same as from time to time applicable to aircraft owned or leased and operated by major U.S. carriers of the
same or similar type similarly on the ground and not in operation, provided that, subject to the self-insurance to the extent
permitted by Section 6.04, the Borrower shall maintain insurance against risk of loss or damage to such Aircraft in an amount at
least equal to the Stipulated Insured Amount during such period that such Aircraft is on the ground and not in operation.

Section 6.03      Reports, Etc.  The Borrower will furnish, or cause to be furnished, to the Collateral Agent and the Administrative
                  -------------
Agent on or before each Delivery Date and annually on or before the renewal dates of the Borrower's relevant insurance policies, a
report, signed by a recognized independent firm of insurance brokers, which brokers may be regularly retained by the Borrower (the
"Insurance Brokers"), describing in reasonable detail the hull and liability insurance then carried and maintained with respect to
------------------
each Aircraft and stating the opinion of such firm that, to the best of its knowledge, such insurance complies with the terms of
Article VI.  Such information shall remain confidential as provided in Section 21 of the Credit Agreement.  The Borrower will cause
the Insurance Brokers to agree to advise the Collateral Agent and the Administrative Agent in writing (a) of any default in the
payment of premium and of any other act or omission on the part of the Borrower of which it has actual knowledge and which will
invalidate or render unenforceable, in whole or in part, any insurance as required by the terms hereof, (b) at least thirty (30) days
(seven (7) days in the case of War Risk Insurance) prior to the cancellation (but not scheduled expiration) or material adverse
change of any insurance maintained pursuant to this Article VI, provided that, in respect of the War Risk Insurance, if the notice
period specified above is not obtainable, the Insurance Brokers shall provide for as long a period of prior notice as shall then be
obtainable and (c) if any of the insurance required by this Article VI are not renewed on the same terms (save as to premium and
period of cover and as the Administrative Agent might otherwise have notified to the Insurance Brokers to be acceptable to the
Administrative Agent and Collateral Agent) seven (7) days prior to expiry thereof.  In the event that the Borrower shall fail to
maintain or cause to be maintained insurance as herein provided, the Administrative Agent may, at its sole option, provide such
insurance and, in such event, the Borrower shall, upon demand, reimburse the Administrative Agent for the cost thereof.

Section 6.04      Self-Insurance.  The Borrower may self-insure, by way of deductible, premium adjustment provisions in insurance
                  --------------
policies, or otherwise, under a program applicable to all aircraft in the Borrower's fleet, the risks required to be insured against
pursuant to Sections 6.01 and 6.02 but in no case shall the self-insurance with respect to an Aircraft exceed $750,000 per
occurrence; provided that no deductible shall be applicable in the case of a total loss of an Airframe.  In the event the prevailing
industry minimum deductible for aircraft similar to the Aircraft increases, the Borrower and Administrative Agent shall consult one
another toward a mutually agreeable modified deductible, such modified deductible to be effective only upon the written consent of
the Administrative Agent (on behalf of the Lender).

Section 6.05      Additional Insurance by Borrower.  The Borrower may carry for its own account at its sole cost and expense insurance
                  --------------------------------
with respect to its interest in the Aircraft, provided that such insurance does not prevent the Borrower from carrying the insurance
required or permitted by this Article VI or adversely affect such insurance provided hereunder or the cost thereof.

Section 6.06      Indemnification by Government in Lieu of Insurance.  Notwithstanding any provisions of this Article VI requiring
                  --------------------------------------------------
insurance, the Administrative Agent on behalf of the Lender agrees to accept, in lieu of insurance against any risk with respect to
the Aircraft, indemnification from, or insurance provided by, the government of the United States of America or any agency or
instrumentality thereof the obligations of which are supported by the full faith and credit of the government of the United States of
America, against such risk in an amount which, when added to the amount of insurance against such risk maintained by the Borrower
shall be at least equal to the amount of insurance against such risk otherwise required by this Article VI (taking into account self
insurance permitted by Section 6.04).  The Borrower shall furnish, in advance of attachment of such indemnity or insurance, if
practical to do so, a certificate of a responsible financial or legal officer of the Borrower confirming in reasonable detail the
amount and scope of such indemnification or insurance and that such indemnification or insurance complies with the preceding sentence.

Section 6.07      Application of Payments During Existence of a Special Default or an Event of Default.  Any amount referred to in
                  ------------------------------------------------------------------------------------
this Article VI which is payable to or retainable by or to be held for the benefit of the Borrower shall not be paid to or retained
by or held for the benefit of the Borrower if at the time of such payment or retention a Special Default or an Event of Default shall
have occurred and be continuing, but shall be held by or paid over to the Administrative Agent, as security for the obligations of
the Borrower under this Mortgage and, if the Collateral Agent, Administrative Agent or Lender, as applicable, shall have declared
this Mortgage or the Credit Agreement to be in default, applied against the Borrower's obligations hereunder as and when due.  At
such time as there shall not be continuing any such Special Default or Event of Default, such amount shall be paid to the Borrower to
the extent not previously applied in accordance with the preceding sentence.

Section 6.08      Terms of Insurance Policies.  Any policies carried in accordance with Sections 6.01 and 6.02 covering the Aircraft,
                  ---------------------------
and any policies taken out in substitution or replacement for any such policies, as applicable, (1) shall name the Additional
Insureds as additional insureds, as their interests may appear, (2) shall name the Administrative Agent (on behalf of the Lender) as
sole loss payee to the extent provided in clause (12) below, (3) may provide for self-insurance to the extent permitted in
Section 6.04, (4) shall provide that if the insurers cancel such insurance for any reason whatsoever, or if any material change is
made in the insurance which adversely affects the interest of any Additional Insured, such cancellation or change shall not be
effective as to the Additional Insureds for thirty (30) days after receipt by (but, in the case of War Risk Insurance, seven (7) days
after sending to) the Additional Insureds of written notice by such insurers of such cancellation or change, provided, however, that
                                                                                                             --------  -------
if, in respect of the War Risk Insurance, any notice period specified above is not obtainable, such policies shall provide for as
long a period of prior notice as shall then be obtainable, (5) shall provide that in respect of the Additional Insureds' respective
interests in such policies the insurance shall not be invalidated by any action or inaction of the Borrower and shall insure the
respective interests of the Additional Insureds regardless of any breach or violation of any warranty, declaration or condition
contained in such policies by the Borrower, (6) shall be primary without any right of contribution from any other insurance which is
carried by any Additional Insured, (7) shall expressly provide that all of the provisions thereof, except the limits of liability,
shall operate in the same manner as if a separate policy covered each insured,  (8) shall waive any right of subrogation of the
insurers or any right of the insurers to set-off or counterclaim or any other deduction, whether by attachment or otherwise, in
respect of any liability of any Additional Insured but only to the extent of the indemnities provided under the Credit Agreement,
(9) shall provide that losses (other than for total loss of an Aircraft) shall be adjusted with the Borrower (or, if an Event of
Default shall have occurred which is continuing, with the Administrative Agent), (10) shall provide that the Additional Insureds are
