imposed  against  or  upon  the  Lessor,  Trustee,  any  Lessor  Lender,  Owner
Participant  or  the  Lessee and relating to or attributable to the Lessee, this
Agreement  or  the  Aircraft  directly  or  indirectly  in  connection  with the
importation,  exportation,  registration,  ownership,  leasing,  sub-leasing,
purchase,  delivery,  possession, use, operation, repair, maintenance, overhaul,
transportation,  landing, storage, presence or redelivery of the Aircraft or any
part  thereof or any rent, receipts, insurance proceeds, income or other amounts
arising  therefrom;  provided,  however, that the Lessee shall have no liability
for Lessor Taxes except to the extent resulting from or increased by any Default
or  the exercise of any right or remedy pursuant to Clause 13.  The verification
provisions  of  Clause  5.11  shall  be applied, upon the Lessee's request, with
respect  to  any  indemnity  payments  due  pursuant  to  this  Clause  5.6.a.

b.     If  the  Lessor,  Trustee, any Lessor Lender or Owner Participant (as the
case  may be) shall, in its reasonable opinion and based upon its own reasonable
interpretation  of any relevant laws or regulations, realize any Tax savings (by
way of refund, deduction, credit or otherwise, including foreign tax credits and
any  reduction  in  Taxes)  in  respect  of any amount with respect to which the
Lessee  shall  have made a payment (or increased payment) pursuant to Clause 5.5
or 5.8, or shall have paid or indemnified the Lessor, Trustee, any Lessor Lender
or  Owner  Participant  pursuant  to  sub-clause (a) above, and such Tax savings
shall  not  have been taken into account previously in calculating any indemnity
payment made by the Lessee, then the Lessor, Trustee, any Lessor Lender or Owner
Participant,  as  the case may be, shall, subject to the Lessee's obligations to
repay  such  amount  to  the  Lessor,  Trustee,  any  Lessor  Lender  or  Owner
Participant,  as  the  case may be, if the relevant Tax savings are subsequently
disallowed  or  canceled  (including by reason of such payment), promptly pay to
the  Lessee  such  amount  as  the  Lessor,  Trustee, any Lessor Lender or Owner
Participant,  as the case may be, shall, in its reasonable opinion (supported by
a  written  calculation thereof setting forth in reasonable detail the basis for
determination),  have  concluded  to be the amount of such Tax savings (together
with,  in the case of a refund, any interest received thereon); provided however
that  none of the Lessor, Trustee, any Lessor Lender nor Owner Participant shall
be  obliged to make any payment to the Lessee pursuant to this sub-clause (b) to
the  extent  that the amount of any Tax savings in respect of which such payment
is  to  be  made would exceed the aggregate amount of all prior payments made by
the  Lessee  to,  on behalf of or as indemnification of the Lessor, Trustee, any
Lessor Lender or Owner Participant, as the case may be, under this Agreement for
Taxes less the amount of all prior payments made pursuant to this sub-clause (b)
in  respect  of  such Tax savings, provided further, that any amount not paid to
the  Lessee  pursuant  to  the  foregoing limitation shall be carried forward to
reduce  pro  tanto  any  future  payments  or  indemnity  that the Lessee may be
required  to make to the Lessor, Trustee, any Lessor Lender or Owner Participant
(as  the  case  may  be)  pursuant  to  Clause  5.5, 5.6(a) and 5.8.  The Lessee
acknowledges  that nothing contained in this sub-clause (b) shall interfere with
the right of the Lessor, Trustee, any Lessor Lender or Owner Participant, as the
case  may be, to arrange its tax affairs in whatsoever manner it thinks fit and,
in  particular,  neither  the  Lessor,  Trustee,  any  Lessor  Lender  nor Owner
Participant  shall  be under any obligation to claim any Tax savings in priority
to  any  other  savings  available  to  it; provided, however, that such Lessor,
Trustee,  any  Lessor Lender or Owner Participant (as the case may be) shall not
discriminate  against  the  Lessee  in  its  use and allocation of any credit or
savings.  Notwithstanding anything to the contrary, each of the Lessor, Trustee,
any  Lessor Lender or Owner Participant, as the case may be, shall in good faith
use  reasonable  diligence  in filing its tax returns and in dealing with taxing
authorities  to  seek  and  claim  any  such  Tax  savings.

5.7.     InformationInformation
         -----------

If  the  Lessee  is  required  by  any applicable law, or by any third party, to
deliver  any report or return in connection with any Taxes, the Lessee will duly
complete  the  same  and  Lessee  will either make such report or return in such
manner  as  will show the ownership of the Aircraft in Lessor and send a copy of
such  report  or  return to Lessor or will notify Lessor of such requirement and
make such report or return in such manner as shall be reasonably satisfactory to
Lessor.  If actual notice is given by any taxing authority to Lessor, Trustee, a
Lessor  Lender or Owner Participant (as the case may be) that a report or return
is  required  to  be  filed  in  its name with respect to any Taxes that are the
responsibility  of  the  Lessee  under this Agreement, the Lessor, Trustee, such
Lessor Lender or Owner Participant shall promptly notify Lessee of such required
report  or  return.  Lessor, Trustee, any Lessor Lender or Owner Participant (as
the  case  may  be)  agrees  to  respond to any reasonable request of Lessee for
information  within  its  control  with  respect  to the filing of any report or
return, but Lessee agrees to duly complete the same or pay any reasonable costs,
fees or other charges of independent counsel or independent accountants incurred
in  connection  with  such  request.  Lessee  shall have no obligation under the
preceding  sentence  if such Lessor, Trustee, Lessor Lender or Owner Participant
(as  the  case may be) has failed to furnish the Lessee with such information as
is  within  such  Lessor's,  Trustee's,  Lessor  Lender's or Owner Participant's
control  and  is  necessary  to  file  such  returns.

5.8.     Taxation  of  Indemnity  PaymentsTaxation  of  Indemnity  Payments
         ---------------------------------

a.     Subject  to the provisions of Clauses 5.10 and 5.11 hereof, if and to the
extent  that any sums payable to the Lessor, Trustee, any Lessor Lender or Owner
Participant,  as  the  case may be, by the Lessee under this Agreement by way of
indemnity  are  insufficient, by reason of any Taxes payable in respect of those
sums,  for  the  Lessor, Trustee, any Lessor Lender or Owner Participant, as the
case  may  be,  to  discharge  the corresponding liability to the relevant third
party  (including  any taxation authority), or to reimburse the Lessor, Trustee,
any  Lessor  Lender  or  Owner  Participant,  as  the  case may be, for the cost
incurred  by  it  to a third party (including any taxation authority) the Lessee
will,  upon  the  written request for payment of such amount, pay to the Lessor,
Trustee, any Lessor Lender or Owner Participant, as the case may be, such sum as
will,  after  the  tax  liability  has  been  fully satisfied, leave the Lessor,
Trustee,  any  Lessor  Lender or Owner Participant, as the case may be, with the
same  amount  as  it  would have been entitled to receive in the absence of that
liability,  together  with  interest on the amount of the deficit at the Default
Rate  in  respect  of  the period commencing on the date on which the payment of
taxation  is finally due or, if later, ten (10) days after the date on which the
Lessor,  Trustee,  Lessor  Lender  or  Owner  Participant,  as  the case may be,
notified  the  Lessee in writing of the deficit and made payment therefor, until
payment  by  the  Lessee  (both  before  and  after  judgment).

b.     Subject  to the provisions of Clauses 5.10 and 5.11 hereof, if and to the
extent  that  any sums constituting (directly or indirectly) an indemnity to the
Lessor, Trustee, any Lessor Lender or Owner Participant, as the case may be, but
paid  by  the  Lessee  to  any Person other than the Lessor, Trustee, any Lessor
Lender  or  Owner Participant, as the case may be, are treated as taxable in the
hands  of  the  Lessor,  Trustee, any Lessor Lender or Owner Participant, as the
case  may  be,  the  Lessee  will,  upon the written request for payment of such
amount,  pay  to the Lessor, Trustee, any Lessor Lender or Owner Participant, as
the  case  may  be,  such  sum  as  will, after the tax liability has been fully
satisfied,  indemnify  the  Lessor,  Trustee,  any  Lessor  Lender  or  Owner
Participant,  as  the  case  may  be,  to  the same extent as it would have been
indemnified  in  the  absence  of  such liability, together with interest on the
amount payable by Lessee under this sub-clause at the Default Rate in respect of
the  period  commencing  on the date on which the payment of taxation is finally
due or, if later, ten (10) days after the date on which the Lessor, Trustee, any
Lessor  Lender  or Owner Participant, as the case may be, notified the Lessee in
writing  of its liability for Taxes with respect to indemnity amounts treated as
taxable  in  the  hands  of  the  Lessor,  Trustee,  any  Lessor Lender or Owner
Participant,  as  the  case may be, until payment by the Lessee (both before and
after  judgment).

5.9.     Default  InterestDefault  Interest
         -----------------

If  the  Lessee  fails to pay any amount payable under this Agreement on the due
date,  the  Lessee  will  pay  on  demand from time to time to the Lessor or any
Indemnitee,  interest  (both  before and after judgment) on the amount, from the
due  date  to  the  day  of  payment  in  full  by  the  Lessee to the Lessor or
Indemnitee, at a per annum rate equal to the lower of (i) the base rate or prime
rate  for commercial loans as announced from time to time by The Chase Manhattan
Bank,  N.A. at its principal lending office in New York, New York, plus 3.0% per
annum  (the  "Default  Rate"),  or  (ii)  the  maximum lawful per annum rate for
commercial  loans.  In  addition, should Lessee's failure to pay extend past the
time  period  set  forth  in  Section  13.1,  Lessee shall pay one hundred fifty
Dollars  (US$150.00)  per  each  unpaid  invoice.  All  such  interest  will  be
calculated  on  the  basis of the actual number of days elapsed and on a 365 day
year.

5.10.     ContestContest
          -------

If a written claim is made against the Lessor, Trustee, a Lessor Lender or Owner
Participant  for  any  Taxes  for  which  the  Lessee  is responsible under this
Agreement or if the Lessor, Trustee, a Lessor Lender or Owner Participant claims
any  indemnity  hereunder,  such  Lessor,  Trustee,  Lessor  Lender  or  Owner
Participant  shall  promptly  notify the Lessee in writing within 30 days of its
receipt  of  any  written  claim  or  knowledge of any indemnity claim and shall
provide  the  Lessee  such  information  regarding  such claim as the Lessee may
reasonably  request.  If the Lessee disputes the payment of any Taxes payable by
the  Lessor,  Trustee, a Lessor Lender or Owner Participant, as the case may be,
for  which  the Lessee is responsible under this Agreement or the payment of any
indemnity  claimed  hereunder,  the  Lessor,  Trustee,  Lessor  Lender  or Owner
Participant,  as  the  case  may  be,  will  take  such action as the Lessee may
reasonably request, at the Lessee's expense, in good faith diligently to contest
the  validity,  applicability  or  amount of such Taxes by (i) resisting payment
thereof  to  the  extent  permitted  by applicable law, (ii) not paying the same
except  under  protest,  if protest is necessary and proper, (iii) if payment is
made,  using  reasonable  efforts  to  obtain  a  refund  thereof in appropriate
administrative  or  judicial proceedings, and (iv) considering in good faith any
other  reasonable  action  as the Lessee may reasonably request, but will not be
obliged  to  take  any  such  action:

a.     which  the  Lessor,  Trustee,  Lessor Lender or Owner Participant, as the
case may be, considers, in its reasonable judgment, may materially prejudice it;

b.     unless  the  Lessee  shall  have  provided such Person with an opinion of
counsel,  reasonably  acceptable  to such Person, that a reasonable basis exists
for such contest, which the Lessor, Trustee, Lessor Lender or Owner Participant,
as  the  case  may be, considers does not have a reasonable prospect of success;

c.     for  which  the  Lessee has not made adequate provision to the reasonable
satisfaction  of the Lessor, Trustee, Lessor Lender or Owner Participant, as the
case  may  be,  in  respect  of  the  expense  concerned;  or

d.     if  such  action gives rise to any material likelihood of the Aircraft or
any  interest  therein  being  sold,  forfeited or otherwise lost or of criminal
liability  on  the  part  of  the  Lessor,  Trustee,  Lessor  Lender  or  Owner
Participant,  as  the  case  may  be.

In  the  event  of a contest of any Taxes hereunder, the Lessor, Trustee, Lessor
Lender  or Owner Participant (as the case may be) shall keep the Lessee informed
as  to  the  progress  of  the  contest  and  provide  the Lessee with copies of
correspondence  and  other  documents  received  by such Lessor, Trustee, Lessor
Lender  or  Owner  Participant  (as  the case may be) from the taxing authority,
consult  with  the  Lessee if requested by the Lessee, make available for review
and  comment  to  the  Lessee any written documents or materials relating to the
contest  that  such  Lessor, Trustee, Lessor Lender or Owner Participant (as the
case  may  be) proposes to submit to the taxing authority, forward copies of all
material  submissions  made  in such contest, consider in good faith any request
concerning  the  conduct of any such contest and without waiving its right to be
indemnified hereunder with respect to such claim shall not settle any such claim
or contest pursuant to this provision without the written consent of the Lessee.

Any  contest required pursuant to the preceding sentence shall, at the option of
such Lessor, Trustee, Lessor Lender or Owner Participant (as the case may be) be
conducted  by  such  Lessor, Trustee, Lessor Lender or Owner Participant (as the
case  may  be)  or the Lessee in the name of the Lessee or such Lessor, Trustee,
Lessor  Lender  or  Owner  Participant;  provided  however  that if a claim with
respect  to  a  Tax  for  which  the  Lessee has agreed to indemnify the Lessor,
Trustee,  Lessor  Lender  or  Owner  Participant  (as  the  case  may be) can be
contested  separately from the contest of any other Tax of such Lessor, Trustee,
Lessor  Lender  or  Owner  Participant  and  in  the name of the Lessee, and the
separation  of  the contest of such Tax does not prejudice such Lessor, Trustee,
Lessor Lender or Owner Participant in any way, then such Lessor, Trustee, Lessor
Lender  or  Owner Participant shall permit the Lessee, at the Lessee's sole cost
and  expense,  to  contest  such  claim  in  the  Lessee's  name.

If  the Lessor, Trustee, Lessor Lender or Owner Participant (as the case may be)
shall  obtain  a  refund  or  credit of all or any part of any Taxes paid by the
Lessee,  such  Lessor,  Trustee, Lessor Lender or Owner Participant shall pay to
the  Lessee  the  amount  of  such refund or credit (taking into account any Tax
savings  resulting therefrom), net of expenses not already paid or reimbursed by
the Lessee, and any interest fairly attributable thereto plus an amount equal to
the  Tax  savings  realized  by  such  Lessor,  Trustee,  Lessor Lender or Owner
Participant  as a result of any payment to the Lessee pursuant to this sentence.

The  Lessee  shall  not  be  required  to make payment to the Lessor, Trustee, a
Lessor Lender or Owner Participant on any indemnification claim being diligently
contested  pursuant to this Clause 5.10 or in the verification process set forth
in  Clause  5.11  hereof  unless (and only to the extent) the Lessor, Trustee or
Owner  Participant has been required to make any payment of taxes giving rise to
such  indemnification  claim.

5.11.     VerificationVerification
          ------------

The  Lessor,  Trustee, a Lessor Lender or Owner Participant, as the case may be,
shall  provide  the  Lessee, upon the Lessee's request, with a written statement
setting  forth in reasonable detail the computation of the amount of any payment
or increased payment to be made by the Lessee pursuant to Clause 5.5 and 5.8, or
any  indemnity  by  the  Lessee pursuant to Clause 5.6(a), or any Tax savings in
respect  of  which  a  payment  is  to  be made to the Lessee pursuant to Clause
5.6(b).  At the Lessee's request, the amount of any such payments or indemnities
by  the  Lessee  or  payment  by  the  Lessor, Trustee, a Lessor Lender or Owner
Participant  (as the case may be) to the Lessee pursuant to this Agreement shall
be  verified  by  the independent, internationally recognized accounting firm of
the  Lessor,  Trustee,  Lessor  Lender  or  the Owner Participant, as they shall
elect,  or  (if  not) by another firm of accountants mutually acceptable to such
Lessor, Trustee, Lessor Lender or Owner Participant and the Lessee, who shall be
asked  to  verify,  after  consulting with the Lessor, Trustee, Lessor Lender or
Owner Participant (as the case may be), whether such Lessor's, Trustee's, Lessor
Lender's  or  Owner  Participant's  computations  are  correct and to report its
conclusions  to both the Lessee and such Lessor, Trustee, Lessor Lender or Owner
Participant.  The  Lessor,  Trustee,  Lessor Lender or Owner Participant (as the
case  may  be)  and  the Lessee hereby agree to provide the accountants with all
information  and  materials  as  shall  be  reasonably necessary or desirable in
connection  herewith.  The  fees and disbursements of such accounting firm shall
be  paid by the Lessee unless such verification shall result in an adjustment in
the Lessee's favor greater than or equal to the greater of (i) five percent (5%)
of  the  total amount verified, or (ii) the fee charged by such accounting firm,
in  which  case such fee shall be paid by such Lessor, Trustee, Lessor Lender or
Owner  Participant.  Any  information provided to such accountants by the Lessee
or  the Lessor, Trustee, Lessor Lender or Owner Participant (as the case may be)
shall  be  and  remain  the  exclusive  property  of  the Lessee or such Lessor,
Trustee,  Lessor  Lender or Owner Participant and shall be deemed by the parties
to  be  (and  the  accountants will confirm in writing that they will treat such
information  as)  the  private,  proprietary  and  confidential property of such
Lessee,  or Lessor, Trustee, Lessor Lender or Owner Participant, as the case may
be, and no person other than the Lessee or the Lessor, Trustee, Lessor Lender or
Owner  Participant  (as  the  case may be) and the accountants shall be entitled
thereto,  and  all such materials shall be returned to the Lessee or the Lessor,
Trustee,  Lessor  Lender  or  Owner  Participant,  as  the  case  may  be.  Such
accounting  firm shall be requested to make its determination within thirty (30)
days.  In  the event such accounting firm shall determine that such computations
are incorrect, then such firm shall determine what it believes to be the correct
computations.  The  computations  of the accounting firm shall be final, binding
and  conclusive  upon the Lessee and the Lessor, Trustee, Lessor Lender or Owner
Participant  (as  the  case  may be) absent manifest error, and the Lessee shall
have  no  right to inspect the books, records, tax returns or other documents of
or  relating  to  such  Lessor,  Trustee,  Lessor Lender or Owner Participant to
verify  such  computations  or  for any other purpose.  If for any reason Lessee
makes  any  payment  with  respect to Taxes imposed on Lessor, Trustee, a Lessor
Lender  or Owner Participant in respect of the transactions contemplated hereby,
which  Taxes are not the responsibility of Lessee under Section 5.5, 5.6 or 5.8,
then  the  applicable  Lessor, Trustee, Lessor Lender or Owner Participant shall
pay  to  Lessee within ten (10) days of Lessee's demand therefor an amount equal
to the amount paid by Lessee with respect to such Taxes, provided, however, that
no  such  demand  shall be honored unless made within thirty (30) days after the
date  of  such  payment, provided, further, that any such payment made after the
ten  (10) day period described above shall include interest on the amount due at
the  Default  Rate  for  all periods after such ten (10) day period.  If Lessor,
Trustee,  a  Lessor  Lender or Owner Participant shall obtain a refund of all or
any  part  of  such taxes paid by Lessee, such Lessor, Trustee, Lessor Lender or
Owner  Participant  shall  promptly pay to Lessee the amount of such refund less
the  amount of any taxes payable by such Lessor, Trustee, Lessor Lender or Owner
Participant  in  respect  of  the  receipt  of  such  refund.

5.12.     FormsForms
          -----

Each  of  Lessor,  Trustee,  any  Lessor  Lender  or Owner Participant agrees to
furnish  from  time  to time to the Lessee or to such other person as the Lessee
may designate such duly executed and properly completed forms, including but not
limited  to  Internal  Revenue  Service  Form 6166 completed annually, that such
Lessor,  Trustee,  any  Lessor  Lender  or  Owner Participant is legally able to
deliver and as may be necessary in order to claim any reduction of, or exemption
from  any  Tax  which the Lessee may be required to indemnify against hereunder.

5.13.     AbsoluteAbsolute
          --------

The  Lessee's  obligations  under  this Agreement are absolute and unconditional
irrespective  of  any  contingency  whatever  including  (but  not  limited to):

a.     any  right  of  offset,  counterclaim, recoupment, defense or other right
which  either  party  to  this  Agreement  may  have  against  the  other;

b.     any  unavailability  of  the  Aircraft  for  any  reason,  including  a
requisition  of the Aircraft or any prohibition or interruption of, interference
with  or  other restriction against the Lessee's use, operation or possession of
the  Aircraft;

c.     any  lack  or  invalidity  of  title  or  any  other  defect  in  title,
airworthiness,  merchantability,  fitness  for any purpose, condition, design or
operation of any kind or nature of the Aircraft for any particular use or trade,
or  for  registration  or  documentation  under  the  laws  of  any  relevant
jurisdiction,  or  any  Total  Loss in respect of or any damage to the Aircraft;

d.     any  insolvency, bankruptcy, reorganization, arrangement, readjustment of
debt,  dissolution,  liquidation or similar proceedings by or against the Lessor
or  the  Lessee;

e.     any  invalidity,  unenforceability  or  lack  of due authorization of, or
other  defect  in,  this  Agreement;  or

f.     any  other  cause which, but for this provision, would or might otherwise
have  the  effect  of  terminating or in any way affecting any obligation of the
Lessee  under  this  Agreement.

provided,  however,  that  this  Clause  5.13  shall be without prejudice to the
Lessee's right to claim damages and/or other relief from the courts in the event
of  any  breach by the Lessor of its obligations under this Agreement, or in the
event  that,  as  a result of any lack or invalidity of title to the Aircraft on
the  part  of  the  Lessor,  the  Lessee  is  deprived  of its possession of the
Aircraft.

5.14.     Deposit
          -------

The  Lessor  (or one or more Lessor Lenders) shall retain the Deposit during the
Term  as  additional  security for Lessee's obligations under this Agreement. On
the  Delivery Date, the Deposit, together with any interest earned thereon shall
constitute  a  security deposit under this Lease, shall be non-refundable during
the  Term  of  this  Lease,  and  shall be held by Lessor (or one or more Lessor
Lenders) in an interest bearing account (which may be a general account and need
not be segregated) as security for the timely and faithful performance by Lessee
of  all  of  Lessee's  obligations under this Lease. If Lessee fails to pay Rent
hereunder  or  to  pay  any  other sums due or to or to perform any of the other
terms and provisions of this Lease or an Event of Default has otherwise occurred
and  is  continuing hereunder, Lessor may use, apply, draw upon or retain all or
any  portion of the Deposit in partial payment for sums due to Lessor by Lessee,
to compensate Lessor for any sums it may in its reasonable discretion advance as
a  result  of  an Event of Default, or to apply toward losses or expenses Lessor
may  suffer  or  incur  as  a  result  of  the occurrence of an Event of Default
hereunder.  If  Lessor  uses,  draws  upon  or applies all or any portion of the
Deposit,  such application shall not be deemed a cure of any Default or Event of
Default,  and  Lessee  shall  within five (5) Business Days after written demand
therefor deposit with Lessor cash or other collateral acceptable to Lessor in an
amount  sufficient  to restore the Deposit to its original level as set forth in
Schedule 9 hereto, and the failure of Lessee to do so shall be a material breach
of  this  Lease  by  Lessee.  Provided no Default has occurred and is continuing
under  this  Lease,  the  Deposit  shall  be  returned  to Lessee, together with
interest (net of any reasonable fees, commissions and other expenses incurred in
connection  with investment of the Deposit), if any, earned thereon, within five
(5)  Business  Days  following  the Expiry Date, or, if later, the date Lessee's
obligations  relating  to  the return of the Aircraft have been fully performed.

manufacturer,  vendor, maintenance performer, subcontractor or supplier.  Unless
an  Event  of  Default  shall have occurred and be continuing, the Lessor hereby
authorizes  the  Lessee  to  pursue  any claim thereunder in relation to defects
affecting  the  Aircraft, any Engine or Part and the Lessee agrees diligently to
pursue  any material claim which arises at its own cost.  The Lessee will notify
the  Lessor  promptly  upon  becoming  aware of any such claim.  The Lessor will
provide  such  assistance  to  the  Lessee  in  making  a  claim  under any such
warranties  or  customer  and/or  product  support  as the Lessee may reasonably
request,  and,  if  requested  by  the  Lessee and at the Lessee's expense, will
pursue  a  claim  in  its  own  name  where  the  relevant manufacturer, vendor,
maintenance  performer, subcontractor or supplier has refused to acknowledge the
Lessee's  right  to  pursue  that  claim.

6.2.     ProceedsProceeds
         --------

b.     to  compensation  for  loss of use of the Aircraft, an Engine or any Part
during  the  Term;  or

c.     to  costs  incurred  by the Lessee in pursuing such claim (whether or not
proceeds  of  such  claim  are  payable  to  the  Lessee);  or

d.     to any proceeds in an amount less than the Damage Notification Threshold;

supplier  as  a permanent replacement for a defective Engine or Part pursuant to
the  terms of any warranty or customer and/or product support arrangement comply
with  Clause  8.13(a),  are installed on the Aircraft promptly and that title to
any  such  engine or part vests in the Lessor in accordance with this Agreement.
On  installation  those  items  will  be  deemed  to  be  a  Engine  or Part, as
applicable.

6.4.     AgreementAgreement
         ---------

To  the extent any warranties or customer and/or product support relating to the
Aircraft are made available under an agreement between any manufacturer, vendor,
maintenance  performer,  subcontractor or supplier and the Lessee, this Clause 6
is subject to that agreement.  Lessee shall take all such steps as are necessary
and  requested by the Lessor at the end of the Term to ensure the benefit of any
of  those  assignable  warranties  or assignable customer and/or product support
which  have  not  expired  are  vested  in  the  Lessor.

         ----------------------------

The  Lessee  shall:

a.     comply  with  the  law  for  the  time  being  in force in any country or
jurisdiction  in which the Aircraft is being operated which is applicable to the
Aircraft  or  the  use  and  operation  of  the  Aircraft;

b.     not  use  the  Aircraft  in any manner contrary to any requirement of the
Aviation  Authority or the DGAC or the manufacturers of the Aircraft, any Engine
or  any  Part or any rule or regulation of the Aviation Authority or the DGAC or
for  any  purpose for which the Aircraft is not designed or reasonably suitable;
provided,  that, after providing the Lessor with a certificate of its President,
Director  of  Finance or chief internal legal counsel stating all relevant facts
with  respect  thereto,  the  Lessee  may,  in  good  faith  and  by appropriate
procedures, contest the validity or application of any such requirement, rule or
regulation  in  any reasonable manner which does not materially adversely affect
the  Lessor,  or  any  of its interests in or to the Aircraft or this Agreement;

c.     ensure  that the crew and engineers employed by it in connection with the
operation  and  maintenance of the Aircraft have the qualifications and hold the
licenses  required  by  the  Aviation Authority (or the DGAC, if applicable) and
applicable  law;

d.     use  the  Aircraft solely in commercial or other operations for which the
Lessee  is  duly  authorized  by the Aviation Authority, the DGAC and applicable
law;

e.     not  knowingly  use  the  Aircraft  (or  use  it  when  the  Lessee ought
reasonably  to  have  known  that  it  was  being  so used) for the carriage of:

i.     whole animals, living or dead, except in the cargo compartments according
to  IATA  regulations,  and  except  domestic  pet animals carried in a suitable
container  to  prevent the escape of any liquid and to ensure the welfare of the
animal;

ii.     acids,  toxic  chemicals, other corrosive materials, explosives, nuclear
fuels,  nuclear  wastes  or  any  nuclear  assemblies  or  components, except as
permitted for cargo aircraft under the "Restriction of Goods" schedule issued by
IATA  from  time to time and provided that all the requirements for packaging or
otherwise  contained  therein  are  fulfilled;

iii.     any  other goods, materials or items of cargo which could reasonably be
expected  to  cause  damage  to  the  Aircraft and which would not be adequately
covered  by  the  Insurances;  or

iv.     any  illegal  item  or  substance;

f.     not  utilize  the  Aircraft  for  purposes  of  training,  qualifying  or
re-confirming  the  status  of  cockpit  personnel except for the benefit of the
Lessee's  cockpit  personnel,  and then only if the use of the Aircraft for such
purpose is not disproportionate to the use for such purpose of other aircraft of
the  same  type  operated  by  the  Lessee;

g.     not  cause  or  permit  the  Aircraft  to  proceed  to, or remain at, any
location  which is for the time being the subject of a prohibition order (or any
similar  order  or  directive)  by:

i.     any  Government Entity of the State of Registration or the Habitual Base;
or

ii.     any Government Entity of the country in which such location is situated;
or

iii.     any  Government  Entity  having  jurisdiction  over  the  Aircraft;

provided,  however, that the failure of the Lessee to comply with the provisions
of  this  sentence  shall  not  give  rise  to  a Default or an Event of Default
hereunder  where such failure is attributable to a hijacking, medical emergency,
equipment  malfunction,  weather condition, navigational error or other isolated
extraordinary  event  (not  within  the  Lessee's  control)  and  the  Lessee is
diligently  proceeding  to  rectify  such  failure  as  soon  as  is  reasonably
practicable;  and

h.     obtain and maintain in full force all certificates, licenses, permits and
authorizations  required  for the use and operation of the Aircraft for the time
being,  and  for  the  making of payments required by, and the compliance by the
Lessee  with  its  other  obligations  under,  this  Agreement.

a.     all  license  and  registration fees, Taxes (other than Lessor Taxes) and
other amounts of any nature imposed by any Government Entity that are imposed on
the  Lessee  or  for  which  the Lessee is responsible under this Agreement with
respect to the Aircraft, including the ownership, delivery, leasing, possession,
use,  operation,  return,  sale or other disposition of the Aircraft (where such
sale  or  other disposition arises as a consequence of an Event of Default); and

b.     all  rent,  fees, charges, Taxes (other than Lessor Taxes) imposed on the
Lessee  and  other  amounts in respect of any premises where the Aircraft or any
Part  thereof  is  located  from  time  to  time  during  the  Term;

except  to  the  extent  that  such  payment is being contested in good faith by
appropriate  proceedings  in  respect  of  which  adequate  resources  have been
provided  by  the  Lessee  and  non-payment  of  which does not give rise to any
material  likelihood  of  the  Aircraft  or  any  interest  therein  being sold,
forfeited  or otherwise lost or of criminal liability on the part of the Lessor.

8.5.     Sub-LeasingSub-Leasing
         -----------

a.     Lessee  will  not, without the prior written consent of Lessor (except as
set  forth  in  clause  (b)  below),  sub-lease  or  part with possession of the
Aircraft,  the  Engines  or any Part except that Lessee may part with possession
(i)  with  respect  to  the  Aircraft,  the  Engines or any Part to the relevant
manufacturers  for  testing  or  similar  purposes  or  to an Agreed Maintenance
Performer  for  service,  repair,  maintenance or overhaul work, or alterations,
modifications  or  additions  to  the  extent  required  or  permitted  by  this
Agreement, and (ii) with respect to an Engine or Part, as expressly permitted by
this  Agreement.  For  the avoidance of doubt, Lessee shall be entitled to enter
into  "wet  lease"  or  charter  arrangements  with  the Aircraft for short-term
periods  that,  including  all  renewals,  do  not  exceed six months so long as
possession  and  operational  control of the Aircraft remains with the Lessee at
all  times.

b.     Lessee  may  sub-lease  (a  "Sub-Lease")  the  Aircraft to a Cintra Group
Airline,  incorporated  in  the  State  of  Registration  or  the  State  of
Incorporation,  without  the  prior  consent  of  the  Lessor  if  the following
conditions  are  fulfilled:

i.     no  Event  of  Default  shall  have  occurred  and  be  continuing;

ii.     notwithstanding  such  Sub-Lease,  Lessee  shall  remain  primarily
responsible  to  Lessor  hereunder  and  the  Sub-Lease,  by its terms, shall be
expressly  subject  and  subordinate  in  all  respects  to  this  Agreement;

iii.     the  Sub-Lease  shall  include  clauses identical to or having the same
substantive effect as Clauses 2.1 (except that the State of Incorporation may be
the  state  of  incorporation  of  the  relevant sublessee), 8, 9, 13, 15.12 and
Schedule 6 of this Agreement save that a Sub-Lease may impose additional or more
stringent  obligations  on,  or  give  fewer  rights to, any Sub-Lessee than are
imposed  on  Lessee under such provisions of this Agreement and that the term of
the  Sub-Lease  shall  not  be  capable  of  extending  beyond  the Expiry Date;

iv.     the  rights, title and interests of Lessor and the Indemnitees in and to
the  Aircraft  and  this  Agreement shall be duly evidenced and protected to the
reasonable  satisfaction  of  Lessor  and  such  Indemnitee (including as to the
making  of  all  necessary  filings  and  registrations);

v.     Lessee  and  the Sub-Lessee shall have executed and delivered to Lessor a
security  assignment in respect of the Sub-Lease together with an acknowledgment
of such assignment, and, if requested by Lessor or any Lessor Lender, Lessee and
the  Sub-Lessee shall have executed and delivered to Lessor and any mortgagee an
acknowledgment  of  any  assignment by Lessor of such security agreement to such
mortgagee,  each  such  document  to  be  in a form reasonably acceptable to the
Lessor;

vi.     the  Sub-Lessee  shall  be  a  reputable  air carrier and shall hold all
necessary  consents,  licenses,  permits  and  authorizations required under the
applicable  law  of  the state of incorporation or establishment of such carrier
for  the  public  transport of passengers and cargo, and shall not be subject to
any  event  of  the  types  described  in  Clause  13.1(g), (h) or (i) as of the
commencement  of  the  Sub-Lease;

vii.     the  Aircraft  shall  not  be  re-registered  outside  the  State  of
Registration  without  the  prior  written  consent of Lessor which shall not be
unreasonably withheld.  Lessor shall be entitled to withhold such consent if the
suggested  jurisdiction of re-registration is a jurisdiction which Lessor or any
Lessor  Lender reasonably determines to be unacceptable in terms of political or
judicial  risk;

viii.     at  least  five  Business Days prior to the execution by Lessee of any
Sub-Lease,  Lessee  will  provide  Lessor  with a copy of the draft Sub-Lease in
order for Lessor to satisfy itself that the conditions set out in this Clause as
to form of the Sub-Lease are fulfilled.  Prior to delivery of the Aircraft under
any  Sub-Lease,  Lessee  will provide Lessor with an original counterpart of the
Sub-Lease  duly  executed  by  Lessee  and  Sub-Lessee;

ix.     Lessee  shall be responsible for all reasonable costs incurred by Lessor
in  connection  with  the  Sub-Lease;

x.     the  Sub-Lease shall provide that no further subleases of the Aircraft by
the  Sub-Lessee  shall  be  permitted;  and

xi.     Lessee shall give written notice to Lessor of any Sub-Lease at least ten
(10)  days  prior  to  the date on which such Sub-Lease is to be executed (which
notice  shall  include  the  identity  of  any  proposed  change in the State of
Registration  and the Habitual Base of the Aircraft and, if then determined, the
term  and  the  delivery  date  of  the  proposed  sublease).

c.     In  circumstances  where  the  conditions  set  out  in (b) above are not
fulfilled  in relation to any Sub-Lease, the consent of Lessor to such Sub-Lease
shall  be  required.

8.6.     InspectionInspection
         ----------

a.     The Lessor and any Person designated by the Lessor may, at any reasonable
time  and  upon  prior written notice (except in the event of a Default in which
case  no notice is required), visit, inspect and survey the Aircraft, any Engine
or  any  Part  for  the  purpose  of verifying compliance by the Lessee with its
obligations  under this Agreement as to the maintenance, use or operation of the
Aircraft;  provided,  that such inspection shall not unreasonably interfere with
the  operation  of  the  Aircraft  or  the  conduct  of  the  Lessee's business.

b.     The  Lessor  shall bear its own costs and expenses in connection with any
such  visit,  inspection  or  survey  unless  the  visit,  inspection  or survey
discloses  that  the  Lessee is in breach of its material obligations under this
Agreement,  in  which case such costs and expenses, if reasonable, shall be paid
by  the  Lessee  on  demand.

c.     The  Lessor  shall:

i.     have  no  duty  to  make,  or  liability  arising out of, any such visit,
inspection  or  survey;  and

ii.     so  long  as  no  Event  of  Default has occurred and is continuing, not
exercise  such  right  other  than on reasonable notice and so as not to disrupt
unreasonably  the  maintenance  or  operation  of  the  Aircraft.

8.7.     Protection  of  TitleProtection  of  Title
         ---------------------

The  Lessee  shall:

a.     not  do  or knowingly permit to be done or omit or knowingly permit to be
omitted  to  be  done  any  act  or  thing which might reasonably be expected to
jeopardize  the  respective rights, title and interest of the Lessor as owner of
the  Aircraft  and lessor under this Agreement, the right, title and interest of
any  mortgagee  of  the Aircraft and assignee of this Agreement or the validity,
enforceability  or  priority  of  any  Mortgage;

Part  is  relevant, make clear to third parties that title is held by the Lessor
and  is  subject  to  any  Mortgage;

i.     represent  or  hold out the Lessor as carrying goods or passengers on the
Aircraft  or  as  being in any way connected or associated with any operation or
carriage (whether for hire or reward or gratuitously) which may be undertaken by
the  Lessee;  or

ii.     pledge  the  credit  of  the  Lessor;

d.     ensure  that  there  is  always  affixed,  and  not removed or in any way
obscured,  a  fireproof plate (having dimensions of not less than 6 in. x 4 in.)
in  a  location  reasonably  adjacent  to,  and  not  less  prominent  than, the
airworthiness  certificate  for  the  Aircraft  and  in  a  reasonably prominent
position  on  each  Engine  stating:

    "This Aircraft/Engine is leased to Aerovias de Mexico, S.A. de C.V. Owner:
                                                                        -----

                                     ---

and  Lessee  agrees  to make such changes to such lease identification plates as
Lessor  may  reasonably  request  from  time  to time, at the expense of Lessor.

e.     not  create  or  permit to exist any Security Interest upon the Aircraft,
any  Engine  or  any  Part;

f.     not  do or permit to be done anything which may reasonably be expected to
expose  the Aircraft, any Engine or any Part to penalty, forfeiture, impounding,
detention,  appropriation,  damage  or destruction and, without prejudice to the
foregoing,  if  any  such  penalty,  forfeiture,  impounding,  detention,
appropriation,  damage or destruction occurs, give the Lessor notice and use its
best  efforts  to  procure the immediate release of the Aircraft, such Engine or
such  Part,  as  the  case  may  be;

g.     not  abandon  the  Aircraft,  the  Engine  or  any  Part;

h.     pay  or  discharge or cause to be paid or discharged when due and payable

party  acting  by  or  through  Lessee  which  have given or might reasonably be
expected to give rise to a Security Interest over or affecting the Aircraft, any
Engine  or  any  Part;

i.     not  attempt,  or  hold itself out as having any power, to sell, lease or
otherwise  dispose  of  the  Aircraft,  any  Engine  or  any  Part other than as
expressly  permitted  by  this  Agreement;  and

j.     do  or  cause  to be done, at its sole cost and expense, any and all acts
and  things which are required under the terms of any applicable law (other than
Federal  Aviation  Law)  involving any jurisdiction in which Lessee operates, or
any and all acts and things which the Lessor or any Lessor Lender may reasonably
request,  to  perfect  and  preserve Lessor's ownership rights regarding and any
Lessor  Lender's  security  interest  in  and  to  the  Aircraft within any such
jurisdiction.

d.     pursuant  to,  and  in  accordance  with,  Schedule  5,  Clause  2(b); or

e.     i.     during  the  course  of  maintaining,  servicing,  repairing,
overhauling  or  testing  that  Engine  or  the Aircraft, as the case may be; or

ii.     as  part  of  a  normal  engine  or  part  rotation  program;  or

iii.     for  the  purpose  of  making  such  modifications to the Engine or the
Aircraft,  as  the  case  may  be,  as  are  permitted  under  this  Agreement,

and then in each case only if it is reinstalled or replaced by an engine or part
complying  with  Clause 8.13(a) as soon as practicable and in any event no later
than  the  Expiry  Date.

8.13.     Installation  of  Engines  and  PartsInstallation of Engines and Parts
          -------------------------------------

a.     The  Lessee  will  ensure that, except as permitted by this Agreement, no
engine  or  part  is  installed  on  the  Aircraft  unless:

i.     in  the  case  of  an engine, it is an engine of the same model as, or an
improved  or  advanced version of, the Engine it replaces (provided, in the case
of  an  improved  or  advanced  version, it can be installed and operated on the
Airframe  without modification of the Airframe or the engine, whether or not the
other  installed Engine is also such an improved or advanced version) and it has
attached  to  it  a  current  "serviceable  tag"  issued  by the manufacturer or
supplier  indicating  that the engine is new, serviceable or overhauled, and the
Lessee  shall  retain all such tags to the extent required under applicable law;

ii.     in  the  case of a part, it is in as good operating condition, is of the
same  or  a  more  advanced  make  and  model and is of the same interchangeable
modification  status  as  the  replaced  Part  and  has attached to it a current
"serviceable  tag"  issued  by  the manufacturer or supplier indicating that the
part  is  new,  serviceable  or overhauled, and the Lessee shall retain all such
tags to the extent required under applicable law; provided, that the replacement
of  parts  will  not, in the aggregate, result in the material diminution in the
value  or  utility  of  the  Aircraft;

iii.     in  the  case  of a part, it has become and remains the property of the
Lessor  free  from  Security Interests and on installation on the Aircraft will,
without  further  act,  be  subject  to  this  Agreement;  and

iv.     in  each  case,  the  Lessee  has  full  details  as  to  its source and
maintenance  records  as  required  by  the  Aviation  Authority  for  Part  129
operators.

b.     If  no Event of Default has occurred which is continuing, the Lessee will
be  entitled to install any engine or part on the Aircraft by way of replacement
notwithstanding  Clause  8.13(a)  if:

i.     there  is  not  available to the Lessee at the time and in the place that
engine  or part is required to be installed on the Aircraft a replacement engine
or  part  complying  with  the  requirements  of  Clause  8.13(a);

ii.     it  would  result  in an unreasonable disruption of the operation of the
Aircraft or the business of the Lessee to ground the Aircraft until an engine or
part  complying  with  Clause  8.13(a) becomes available for installation on the
Aircraft;  and

iii.     as  soon  as practicable after installation of the same on the Aircraft
but,  in  any  event, no later than the Expiry Date, the Lessee removes any such
engine  or  part and replaces it with the Engine or Part replaced by it or by an
engine  or  part  complying  with  Clause  8.13(a).

c.     The  Lessor  agrees,  for  the benefit of the Lessee and any mortgagee or
holder  of  any  other  Security  Interest  in any engine or part (other than an
Engine  or  Part)  owned  by the Lessee, any lessor of any engine or part (other
than  an  Engine or Part leased to the Lessee) and any conditional vendor of any
engine  or part (other than an Engine or Part purchased by the Lessee subject to
a  conditional  sale  agreement or any other security agreement), that no right,
title  to  or interest in any such engine or part shall be exercised or asserted
by  the Lessor and the Lessor acknowledges and confirms that it will not acquire
any right, title or interest to or in any such engine or part as a result of its
installation  on  the  Airframe.

8.14     Non-Installed  Engines  and  PartsNon-Installed  Engines  and  Parts
         ----------------------------------

a.     The Lessee shall ensure that any Engine or Part which is not installed on
the  Airframe  (or any other airframe as permitted by this Agreement) is, except
as  expressly  permitted  by this Agreement, properly and safely stored and kept
free  from  Security  Interests.

b.     Notwithstanding  sub-clause  (a),  the  Lessee  shall be permitted, if no
Event  of  Default  has  occurred and is continuing, to install any Engine on an
airframe  and  any  Part  on  an  airframe  or  engine:

i.     owned  and  operated  by  the  Lessee  free  from  Security Interests; or

ii.     operated  by  the  Lessee  and  either (1) leased or hired to the Lessee
pursuant  to  a  lease or conditional sale agreement on terms whereby the Lessee
has  full  operational  control  of that aircraft or engine, or (2) owned by the
Lessee  and  subject to a mortgage, a lease, conditional sale agreement or other
agreement  that  constitutes  a Security Interest vested in or held by any other
Person,  provided  that:

(A)     the  terms  of  any  such  lease, conditional sale agreement or Security
Interest  will  not have the effect of prejudicing the title and interest of the
Lessor  or  any  mortgagee  in  and  to  that  Engine  or  Part;  and

(B)     the  lessor  under  such  lease,  the seller under such conditional sale
agreement or the secured party of any Security Interest, as the case may be, has
confirmed and acknowledged in writing (which confirmation and acknowledgment may
be  contained  in the lease, conditional sale agreement or document creating the
Security  Interest) to the Lessor, in form and substance reasonably satisfactory
to  the  Lessor,  that  it  will recognize the rights, title and interest of the
Lessor  and  any  mortgagee  to  and in that Engine or Part and that it will not
acquire  any  rights  of  ownership  whatever  in  relation  thereto.

8.15.     Pooling  of  Engines  and  PartsPooling  of  Engines  and  Parts
          --------------------------------

The  Lessee  will not enter into nor permit any pooling agreement or arrangement
in respect of an Engine or Part without the prior written consent of the Lessor,
such consent not to be unreasonably withheld in any case where an Engine or Part
is  leased,  let  on  hire  or  otherwise made available by the Lessee (on terms
conferring  no  more than a contractual right in personam against the Lessee and
not  a right in rem against such Engine or Part) pursuant to a pooling agreement
to  which  the  Lessee  is  a  party  and:

a.     the other parties to which are reputable, solvent commercial air carriers
or  the  manufacturers  or  suppliers of the Engine or Part (or other reputable,
solvent  organizations  whose  business  includes  the  administration  of  and
participation  in  such  pooling  agreements  or  arrangements);  and

b.     which  does not contemplate the transfer of title to the pooled Engine or
Part;  and

c.     either  provides  that the Lessor (or any mortgagee designated by Lessor)
will  be sole loss payee in respect of any loss or damage to the Engine or Part,
or  provides  for  Lessor  to  acquire  title  to  a  substitute  engine or part
satisfying  the  conditions  set  out in Clause 8.13(a) if the Engine or Part is
destroyed.

8.16.     Equipment  ChangesEquipment  Changes
          ------------------

a.     The  Lessee  will  not  make any modification or addition to the Aircraft
(each  an  "Equipment  Change"),  except  for  an  Equipment  Change  that:

i.     is  expressly  permitted  or  required  by  any  other  provision of this
Agreement,  or

ii.     the  Lessee  may  deem  desirable in the proper conduct of its business,
provided that no such Equipment Change impairs the condition or airworthiness of
the  Aircraft,  or diminishes the value, useful life or utility of the Airframe,
Engine  or  Part,  or

iii.     has  the  prior  written  approval  of  the  Lessor,  or

iv.     is  made  in  order  to  conform  the  configuration  of the Aircraft to
Lessee's  standard  configuration  for  MD-87  aircraft.

b.     So long as no Event of Default has occurred and is continuing, the Lessee
may  remove  any Equipment Change if it can be removed from the Aircraft without
diminishing  or  impairing the value, utility, condition or airworthiness of the
Aircraft  as  compared  to  its  value,  utility,  condition  or  airworthiness
immediately  prior  to  the  Equipment  Change  assuming the Aircraft was in the
condition  required  by  this  Agreement  prior  to  the  Equipment  Change.

8.17.     Title  to  PartsTitle  to  Parts
          ----------------

a.     Subject  to Clause 8.13(c), title to all parts installed on the Aircraft,
whether  by way of replacement as the result of an Equipment Change or otherwise
(except  those  installed  pursuant  to  Clause  8.13(b) or Clause 8.15) will on
installation,  without further act, vest in the Lessor subject to this Agreement
free  and  clear  of all Security Interests.  The Lessee will at its own expense
take  all  such  steps  and  execute,  and  procure  the  execution of, all such
instruments  that  are  necessary  to  ensure that title so passes to the Lessor
according to all applicable laws.  At any time when requested by the Lessor, the
Lessee  will provide evidence to the Lessor's reasonable satisfaction (including
the  provision,  if required, to the Lessor of a legal opinion of Lessee's chief
internal  counsel)  that  title  has  so  passed  to  the  Lessor.

b.     Except  as  referred to in Clause 8.16(b), any Engine or Part at any time
removed  from  the  Aircraft  will  remain  the  property  of the Lessor until a
replacement  has  been made in accordance with this Agreement and until title to
that replacement has passed, according to applicable laws, to the Lessor subject
to  this Agreement free of all Security Interests, whereupon title to the Engine
or  Part will, provided no Event of Default has occurred and is continuing, pass
to  the  Lessee.


8.18     Third  PartiesThird  Parties
         --------------

The  Lessee shall ensure that no Person having possession of the Aircraft during
the  Term  (other  than  the  Lessor or any party acting through or on behalf of
Lessor)  will act in any manner inconsistent with the Lessee's obligations under
this  Agreement and that all such Persons shall comply with those obligations as
if  references  to  "Lessee"  included  a  separate  reference to those Persons.

9.     INSURANCEINSURANCE
       ---------

9.1.     InsurancesInsurances
         ----------

The  Lessee will maintain in full force and effect during the Term insurances in
respect  of  the  Aircraft  in form and substance reasonably satisfactory to the
Lessor (the "Insurances" which expression includes, where the context so admits,
any  relevant  re-insurances).  The  Insurances  will  be  effected  either:

a.     on  a  direct  basis  with  insurers  of recognized standing who normally
participate  in  aviation  insurances  in  the  leading  international insurance
markets and led by reputable underwriters reasonably satisfactory to the Lessor;
or

b.     with a single insurer or group of insurers reasonably satisfactory to the
Lessor  who does not retain the risk, but effects substantial reinsurance in the
leading  international  insurance  markets  and through brokers and underwriters
each  of  recognized  standing  and  reasonably  acceptable  to the Lessor for a
percentage  reasonably  acceptable  to  the  Lessor  of  all  risks insured (the
"Reinsurances"),

and  the  Lessor  acknowledges  and  confirms  that  the current deductibles and
exclusions,  together  with  the existing brokers and insurers in respect of the
insurances  maintained by Lessee on the date of this Agreement are acceptable to
it.

9.2.     RequirementsRequirements
         ------------

The  Lessor's  current  requirements  as  to Insurances are as specified in this
Clause  and in Part 1 of Schedule 6.  The Lessor may from time to time stipulate
such  other  requirements  for the Insurances as the Lessor reasonably considers
necessary  to  ensure  that  the  scope  and  level  of  cover  is maintained in
accordance with the then prevailing industry practice in relation to aircraft of
the  same  type as the Aircraft and in relation to operators of similar standing
to  the  Lessee.  In the event that the Lessor proposes any such stipulation, it
shall  notify the Lessee accordingly and the Lessor and/or its brokers will then
consult  in  good  faith with the Lessee and the Lessee's brokers with regard to
such  proposed  stipulation.  If, following the consultation, the Lessor and the
Lessee  are satisfied that the stipulation should be made, the Lessee shall then
comply with the stipulated requirements.  If, however, the Lessor and the Lessee
do  not agree regarding the proposed stipulation, the Lessor and the Lessee (and
their respective brokers) shall agree upon and name a third broker, to determine
whether  the  proposed stipulation is required in order to ensure that the scope
and level of cover is maintained in accordance with the then prevailing industry
practice  in  relation to aircraft of the same type and in relation to operators
of  similar standing to the Lessee.  The party whose position is not accepted by
the  third  broker shall pay all costs and expenses of such broker in connection
with  the  making  of  its  determination.

9.3.     Insurance  CovenantsInsurance  Covenants
         --------------------

The  Lessee  shall:

a.     ensure  that  all legal requirements as to insurance of the Aircraft, any
Engine  or  any  Part  that  may from time to time be imposed by the laws of the
State  of  Registration  or any jurisdiction to, from or over which the Aircraft
may be flown, in so far as they affect or concern the operation of the Aircraft,
are  complied  with and, in particular, those requirements compliance with which
is  necessary  to  ensure  that:

i.     the  Aircraft  does  not  become  subject  to  detention  or  forfeiture;

ii.     the  Insurances  remain  valid  and  in  full  force  and  effect;  and

iii.     the  interests of the Indemnitees in the Insurances and the Aircraft or
any  Part  are  not  thereby  prejudiced;

b.     not  use, cause or permit the Aircraft, any Engine or any Part to be used
for  any  purpose  or in any manner not covered by the Insurances or outside any
geographical  limit  imposed  by  the  Insurances;

c.     comply with the terms and conditions of each policy of the Insurances and
not  do,  consent  or  agree  to  any  act  or  omission  that:

i.     invalidates  or  may reasonably be expected to invalidate the Insurances;

ii.     renders  or  may  reasonably  be expected to render void or voidable the
whole  or  any  part  of  any  of  the  Insurances;  or

iii.     brings  any  particular  liability  within  the  scope of an exclusion,
exception  or  sub-limit  to  the  Insurances;

d.     not  take  out  without  the  prior  written  approval  of the Lessor any
insurance or reinsurance in respect of the Aircraft other than those required or
permitted  under  this  Agreement  unless  relating  solely  to hull total loss,
business interruption, engine break-down, profit commission and deductible risk;

e.     commence  renewal  procedures at least 30 days prior to the expiration of
any  of  the  Insurances  and  provide  to  the  Lessor:

i.     if  requested  by  the  Lessor,  a  written  status  report  of  renewal
negotiations  14  days  prior  to  each  expiration  date;

ii.     telefaxed confirmation of completion of renewal prior to each expiration
date;  and

iii.     certificates  of  insurance  (and  where  appropriate  certificates  of
reinsurance),  and broker's (and any reinsurance brokers') letter of undertaking
substantially  in the form set out in Parts 2 and 3 of Schedule 6, detailing the
coverage  and  confirming  the  insurers' (and any reinsurers') agreement to the
specified  insurance requirements of this Agreement within seven days after each
renewal  date;

f.     provide to the Lessor copies of those documents evidencing the Insurances
which the Lessor may reasonably request (but not including information regarding
premiums);

g.     on  request,  provide  to the Lessor evidence that the Insurance premiums
have  been  paid;

h.     not  make  any  modification or alteration to the Insurances material and
adverse  to  the  interests  of  any  of  the  Indemnitees;

i.     be  responsible  for  any  deductible  under  the  Insurances;  and

j.     provide  any  other  insurance  and  reinsurance  related information, or
assistance,  in  respect  of the Insurances as the Lessor may reasonably request
(but  not  including  copies  of  the insurance policies (unless a dispute as to
coverage  arises)  or  information  regarding  premiums).

9.4.     Failure  to  InsureFailure  to  Insure
         -------------------

If  the  Lessee  fails  to  maintain  the  Insurances  in  compliance  with this
Agreement,  or to provide Lessor with the evidence thereof required under Clause
9, each of the Indemnitees will be entitled but not obligated (without prejudice
to  any  other  rights  of  the  Lessor  under  this  Agreement):

a.     to pay the premiums due or to effect and maintain insurances satisfactory
to  it  or  otherwise  remedy  the Lessee's failure in such manner (including to
effect  and  maintain an "owner's interest" policy) as it considers appropriate.
Any sums so expended by it will become immediately due and payable by the Lessee
to  the  Lessor on demand (and Lessor will endeavor to make such demand promptly
following  the incurring of such expenditure), together with interest thereon at
the  Default  Rate  from  the  date  of  expenditure  by  it  up  to the date of
reimbursement  by  the  Lessee  (before  and  after  any  judgment);  and

b.     at  any  time while such failure is continuing to require the Aircraft to
remain  at  any airport or to proceed to and remain at any airport designated by
it  until  the  failure  is  remedied  to  its  reasonable  satisfaction.

9.5.     Continuing  IndemnityContinuing  Indemnity
         ---------------------

The  Lessor may require the Lessee to effect and to maintain insurance after the
Expiry Date with respect to its liability under the indemnities in Clause 10 for
such period as the Lessor may reasonably require (but in any event not more than
the  lesser  of  two  years or until the next Major Check which "zero times" the
Aircraft  under  MSG-3)  providing for each Indemnitee to be named as additional
insured.  The Lessee's obligation under this Clause 9.6 shall not be affected by
the  Lessee  ceasing  to  be  lessee  of  the Aircraft or any of the Indemnitees
ceasing  to  have any interest in respect of the Aircraft.  Such insurance shall
be  maintained  at  the  cost of Lessee until the Aircraft has been returned and
Lessee  has  performed  its  obligations  relating  to  such  return  under this
Agreement  and,  thereafter,  at  the  cost  of  Lessor.

9.6.     Application  of  Insurance  ProceedsApplication  of  Insurance Proceeds
         ------------------------------------

As  between  the  Lessor  and  the  Lessee:

a.     All  insurance  payments  received  as  the  result of a Total Loss or an
Engine  Loss  occurring  during  the  Term  will  be  paid to the Lessor (or any
mortgagee  designated  by Lessor), and the Lessor shall promptly pay the balance
of  those  amounts  to  the  Lessee  after deduction of all amounts then due and
payable by the Lessee to the Lessor under this Agreement, including under Clause
11.1(b)  and  Clause  11.1(c).

b.     All  insurance proceeds in respect of any damage or loss to the Aircraft,
any  Engine  or any Part occurring during the Term not constituting a Total Loss
and  in  excess  of the Damage Notification Threshold will be paid to the Lessor
(or any mortgagee designated by Lessor)  and applied in payment (or to reimburse
the Lessee) for repairs or replacement property upon the Lessor being reasonably
satisfied  that the repairs or replacement have been effected in accordance with
this  Agreement.  The  insurer  may  pay insurance proceeds in amounts below the
Damage  Notification  Threshold  directly  to the Lessee.  Any balance remaining
shall  be  paid  to  or  retained  by  the  Lessee.

c.     All  insurance  proceeds in respect of third party liability will, except
to  the  extent paid by the insurers to the relevant third party, be paid to the
Lessor to be paid directly in satisfaction of the relevant liability or promptly
to  the  Lessee  in  reimbursement  of  any  payment  so  made.

d.     Notwithstanding  Clauses  9.6(a),  (b)  and  (c),  if  at the time of the
payment  of any such insurance proceeds a Default has occurred and is continuing
all  such  proceeds  will be paid to or retained by the Lessor (or any mortgagee
designated  by Lessor)  to be applied toward payment of any amounts then due and
payable  by the Lessee in such order as the Lessor sees fit or as the Lessor may
elect.  In the event that the Lessee remedies any such Default to the reasonable
satisfaction  of  the  Lessor,  the Lessor shall procure that all such insurance
proceeds  then  held  by the Lessor in excess of the amounts (if any) applied by
the  Lessor  (or  any  mortgagee  designated by Lessor)  in accordance with this
sub-clause  (d)  shall  be  paid  promptly  to  the  Lessee.

9.7.     Additional  InsuranceAdditional  Insurance
         ---------------------

The  Lessee agrees to procure any additional Insurances as at any time requested
by the Lessor and Lessor agrees to reimburse the Lessee for the cost of, and all
reasonable  expenses  incurred  in  obtaining,  any  such additional Insurances.

10.     INDEMNITYINDEMNITY
        ---------

10.1.     GeneralGeneral
          -------

The  Lessee  shall  defend, indemnify and hold harmless the Indemnitees from and
against  any and all claims, proceedings, losses, liabilities, suits, judgments,
costs, expenses, penalties or fines (each a "Claim") regardless of when the same
is  made  or  incurred,  whether  during  or  after  the  Term (but not before):

a.     that  may at any time be suffered or incurred directly or indirectly as a
result  of  or  connected  with  possession,  delivery, performance, management,
registration,  control,  maintenance,  condition,  service,  repair,  overhaul,
leasing,  sub-leasing,  use,  operation or return of the Aircraft, any Engine or
Part  (either  in  the  air  or  on  the ground) whether or not the Claim may be
attributable  to  any  defect  in the Aircraft, any Engine or any Part or to its
design,  testing,  use  or  otherwise, and regardless of when the same arises or
whether it arises out of or is attributable to any act or omission, negligent or
otherwise,  of  any  Indemnitee;

b.     that  arise  out  of any act or omission that invalidates or that renders
voidable  any  of  the  Insurances;

c.     that  may  at  any  time  be suffered or incurred as a consequence of any
design,  article  or  material  in  the  Aircraft, any Engine or any Part or its
operation  or  use constituting an infringement of patent, copyright, trademark,
design  or  other  proprietary  right  or  a  breach  of  any  obligation  of
confidentiality  owed  to  any  Person,

but  excluding  any  Claim  to  the  extent  that:

i.     it  arises  as  a result of the willful misconduct or gross negligence of
such  Indemnitee;

ii.     it  arises  as  a  result  of  a  breach  by  the  Lessor of its express
obligations  under this Agreement or as a result of a representation or warranty
given  by  the  Lessor  in this Agreement not being true and correct at the date
when,  or  when  deemed  to  have  been,  given  or  made;

iii.     it  constitutes  a  Lessor  Tax  or  Lessor  Lien;

iv.     it  represents  a  Tax or loss of tax benefits (the Lessee's liabilities
for  which,  to  the  extent  thereof, are set out in Clauses 5.5, 5.6 and 5.8);

v.     it  constitutes  a  cost  or  expense that is required to be borne by the
Lessor  in  accordance  with  any  other  provision  of  this  Agreement;

vi.     it  results  from  any voluntary disposition by the Lessor of all or any
part  of  its  rights,  title  or  interest  in or to the Aircraft or under this
Agreement,  unless  such  disposition  occurs  as  a  consequence of an Event of
Default;  or

vii.     it  is  attributable  to  an  event occurring after the Term unless the
Claim  results  from  or  arises out of an act or omission by the Lessee, or any
circumstance  existing,  during  the  Term.

10.2.     MitigationMitigation
          ----------

a.     The  Lessor agrees that it shall, as soon as reasonably practicable after
it  becomes  aware  of  any  circumstances  that  would,  or would reasonably be
expected  to,  become  the  subject  of  a claim for indemnification pursuant to
Clause  10.1,  notify  the  Lessee  in writing accordingly.  The Lessor (and any
other  Indemnitee  seeking  indemnification,  as the case may be) and the Lessee
shall  then  consult  with  one another in good faith in order to determine what
action  (if  any)  may reasonably be taken to avoid or mitigate such Claim.  The
Lessee  shall  have  the  right to take all reasonable action (on behalf and, if
necessary,  in  the  name  of  the  Lessor or such other Indemnitee) in order to
resist,  defend or settle (provided such settlement is accompanied by payment in
full  and  requires  no  admissions  or covenants by Lessor) any claims by third
parties  giving rise to such Claim, provided always that the Lessee shall not be
entitled  to  take  any  such  action  unless  adequate  provision,  reasonably
satisfactory  to  the  Lessor and such other Indemnitee, shall have been made in
respect  of  the third party claim and the costs thereof.  The Lessee or, if the
Lessee's  insurers  have  confirmed  that  the  Claim  is  covered  by  Lessee's
Insurances,  the  Lessee's  insurers  shall be entitled to select any counsel to
represent  it  or  them, the Lessor and such other Indemnitee in connection with
any such action, subject in the case of Lessee to the approval of the Lessor and
such  other  Indemnitee  (such approval not to be unreasonably withheld) and any
action  taken by the Lessee shall be on a full indemnity basis in respect of the
Lessor  and  such  other  Indemnitee.

b.     Any sums paid by the Lessee to the Lessor or any Indemnitee in respect of
any  Claim  pursuant to Clause 10.1 shall be paid subject to the condition that,
in  the  event  that the Lessor or such Indemnitee is subsequently reimbursed in
respect  of that Claim by any other Person, the Lessor or such Indemnitee shall,
provided  no  Default shall have occurred and be continuing, promptly pay to the
Lessee  an  amount  equal  to  the  sum  paid to it by the Lessee, including any
interest  on  such amount to the extent attributable thereto and received by the
Lessor or such Indemnitee, less any Tax payable by the Lessor or such Indemnitee
in  respect  of  such  reimbursement.

c.     Upon  the  making  of  any indemnity payment pursuant to Clause 10.1, the
Lessee, without any further action, shall be subrogated to any claims the Lessor
may  have  relating thereto to the extent of such payment.  The Lessor agrees to
give  such  further assurances or agreements and to cooperate with the Lessee to
permit  the  Lessee  to  pursue  such  claims,  if any, to the extent reasonably
requested  by  the  Lessee  and  at  the  Lessee's  sole  cost  and  expense.

d.     In  the  event  that  the  Lessee shall have paid an amount to the Lessor
pursuant  to  Clause  10.1,  and  the Lessor subsequently shall be reimbursed in
respect  of  such  indemnified  amount  from  any other person, the Lessor shall
promptly (but not before the Lessee shall have made all payments then due to the
Lessor  under this Agreement) pay to the Lessee an amount equal to the amount of
such  reimbursement.

        ----------------

11.1.     Total  LossTotal  Loss
          -----------

a.     Pre-delivery:  If  a  Total Loss occurs prior to Delivery, this Agreement
       ------------
will  immediately  terminate  and, except as expressly stated in this Agreement,
neither party will have any further obligation or liability under this Agreement
except  that  the  Lessor  will  return  to the Lessee the Deposit and any other
amounts  paid  by the Lessee to the Lessor with respect to the Aircraft prior to
Delivery.

b.     Post-delivery:  If  a  Total  Loss occurs after Delivery, the Lessee will
       -------------
pay to the Lessor (or any mortgagee designated by Lessor), no later than 90 days
after  the Total Loss Date (the "Settlement Date"), the Termination Value on the
Settlement  Date,  less  any portion of Basic Rent previously paid by the Lessee
and corresponding to periods after the date of such payment, unless the Aircraft
is restored to the Lessor or the Lessee within that period (or, in the case of a
Total  Loss  coming  within  paragraph  (c)  of the definition of Total Loss and
involving  the  loss of the Lessor's title to the Aircraft, if both the Aircraft
and the Lessor's title thereto are restored to the Lessor or, in the case of the
Aircraft,  to  the  Lessee).  The  receipt  by  the  Lessor  (or  any  mortgagee
designated  by Lessor) of the insurance proceeds in respect of the Total Loss on
or  prior  to the Settlement Date shall discharge the Lessee from its obligation
to  pay  the  Termination  Value  to the Lessor pursuant to this sub-clause (b),
provided  such  proceeds  are  not  less than an amount equal to the Termination
Value  less  an amount equal to the portion of any Basic Rent previously paid by
the  Lessee and corresponding to periods after the date of such payment.  In the
event  that  the  insurance proceeds are paid initially to the Lessee and not to
the Lessor, they may be retained by the Lessee if the Lessee shall have paid the
Termination  Value,  less  an  amount  equal  to  the  portion of any Basic Rent
previously  paid  by  the  Lessee and corresponding to periods after the date of
such  payment,  to  the  Lessor; otherwise, the Lessee shall pay the Termination
Value,  less an amount equal to the portion of any Basic Rent previously paid by
the  Lessee  and corresponding to periods after the date of such payment, to the
Lessor  within  two  (2)  Business  Days following receipt by the Lessee of such
proceeds.  In  the  event  that  the  Lessee pays the Termination Value, less an
amount  equal to the portion of any Basic Rent previously paid by the Lessee and
corresponding  to  periods  after  the  date  of  such payment, to the Lessor in
accordance  with  this  sub-clause  (b), the Lessor shall promptly assign to the
Lessee  its  rights  under  the  Insurances to receive the insurance proceeds in
respect  of  the Total Loss to the extent that such proceeds shall not have been
paid  to  the  Lessee.  Subject  to the rights of any insurers and reinsurers or
other  third  parties,  upon  irrevocable  payment in full to the Lessor of that
amount  and  all  other  amounts  then  due and payable to the Lessor under this
Agreement,  the  Lessor  shall,  without  recourse or warranty (except as to the
absence  of  Lessor  Liens  and  as  to  good and marketable title), and without
further  act,  be  deemed  to have transferred to the Lessee all of the Lessor's
rights  to  any Engines or Parts not installed when the Total Loss occurred, all
on  an  "as-is, where is" basis, and shall, at the Lessee's expense, execute and
deliver such bills of sale and other documents and instruments as the Lessee may
reasonably  request to evidence (on the public record or otherwise) the transfer
and  the vesting of the Lessor's rights in such Engines and Parts in the Lessee,
free  and  clear  of  all  rights  of  the  Lessor  and  any  Lessor  Liens.

c.     Engine  Loss:  Upon  the occurrence of an Engine Loss (including, for the
       ------------
avoidance  of doubt, at a time when the Engine is not installed on the Airframe)
in  circumstances  in which there has not also occurred a Total Loss, the Lessee
shall  give  the  Lessor written notice promptly upon becoming aware of the same
and  shall  (unless  the  Lessor has received the insurance proceeds relating to
such Engine Loss), within 90 days after the Engine Loss Date, convey or cause to
be  conveyed  to  the  Lessor,  as  replacement  for  such  Engine,  title  to a
replacement  engine  that  is  in the same or better operating condition, has as
many  or more Flight Hours and Cycles available until the next scheduled checks,
inspections,  overhauls  and  shop  visits and has the same or greater value and
utility  as  the  lost  Engine  and that complies with the conditions set out in
Clause  8.13(a).  The  Lessee  will  at  its own expense take all such steps and
execute,  and  procure the execution of, all such instruments that are necessary
to ensure that title to the replacement engine passes to the Lessor according to
all  applicable  laws,  and if requested by the Lessor, will provide evidence to
the  Lessor's  reasonable satisfaction (including the provision, if required, to
the  Lessor  of  a legal opinion of counsel to Lessee reasonably satisfactory to
Lessor)  that  title  has  so passed to the Lessor, whereupon the leasing of the
replaced  Engine  the  subject  of the Engine Loss shall cease and title to such
replaced  Engine  shall  (subject to any salvage rights of insurers) vest in the
Lessee  pursuant  to  Clause  8.17(c).  If  the Lessor subsequently receives any
insurance proceeds relating to such Engine Loss, the Lessor shall promptly remit
such  proceeds to the Lessee.  No Engine Loss with respect to any Engine that is
replaced  in  accordance with the provisions of this Clause 11.1(c) shall result
in  any  increase  or  decrease  in  Basic  Rent  or  the  Termination  Value.

11.2.     RequisitionRequisition
          -----------

During  any requisition for use or hire of the Aircraft, any Engine or Part that
does  not  constitute  a  Total  Loss:

a.     the  Basic  Rent  and Supplemental Rent payable under this Agreement will
not  be  suspended or abated either in whole or in part, and the Lessee will not
be  released  from any of its other obligations under this Agreement (other than
operational  obligations  with  which  the  Lessee is unable to comply solely by
virtue  of  the  requisition);  and

b.     so long as no Event of Default has occurred and is continuing, the Lessee
will  be entitled to any compensation payable by the requisitioning authority in
respect  of  the Term.  The Lessee will, as soon as practicable after the end of
any  such  requisition, cause the Aircraft to be put into the condition required
by  this  Agreement.  The Lessor will be entitled to all compensation payable by
the requisitioning authority in respect of any change in the structure, state or
condition  of  the  Aircraft  arising  during the period of requisition, and the
Lessor  will  apply  such compensation in reimbursing the Lessee for the cost of
complying  with  its  obligations  under  this  Agreement in respect of any such
change, but so that, if any Event of Default has occurred and is continuing, the
Lessor  may apply the compensation in or towards settlement of any amounts owing
by  the  Lessee  under  this  Agreement.  The  Lessor  shall hold all such sums.

12.     RETURN  OF  AIRCRAFTRETURN  OF  AIRCRAFT
        --------------------

12.1.     RedeliveryRedelivery
          ----------

On  the  Expiry  Date  or  termination of the leasing of the Aircraft under this
Agreement,  the  Lessee shall, unless a Total Loss has occurred, at its expense,
redeliver  the  Aircraft  and Aircraft Documents to the Lessor at the Redelivery
Location  in  a condition complying with this Clause 12 and Schedule 5, free and
clear  of  all  Security Interests (other than Lessor Liens); provided, however,
that  if  Lessor  designates an alternate Redelivery Location in the continental
United States of America then the Lessor shall reimburse the Lessee for the cost
of  a  ferry  flight  from  Mexico  City  International  Airport (or such closer
location  at  which  Lessee  has  then  placed  the  Aircraft) to such alternate
Redelivery  Location,  provided,  however,  that  if  such  cost is in excess of
$15,000.00  any excess shall not be reimbursed and shall be borne by the Lessee.

12.2.     Final  ChecksFinal  Checks
          -------------

Immediately prior to return of the Aircraft, Lessee shall perform the following:

a.     Lessee  shall  perform  (or  have  performed  by  an  Agreed  Maintenance
Performer)  a  "C"  check  or  its  equivalent, the work, if any, required to be
performed  within  thirty (30) days thereafter in accordance with the heavy work
cards,  the corresponding lower checks ("A" and "B" or equivalent) and any other
maintenance  and  inspections  tasks  that are a part thereof, all in accordance
with  the  Agreed  Maintenance  Program.  At return, the Airframe will have zero
Flight  Hours  since  such  "C"  check  or  its  equivalent  and  any such heavy
maintenance  work, except for the acceptance flights and the ferry flight to the
Redelivery  Location.  Lessee  will  also weigh the Aircraft.  Lessee shall also
perform during such check any other work reasonably requested by Lessor (and not
otherwise  required  under this Agreement) so long as such work does not prevent
Lessee  from  returning  the  Aircraft  on  the  Expiry  Date,  and Lessor shall
reimburse Lessee for the cost of such work based on its third-party labor rates.
The Lessor shall indemnify and hold harmless the Lessee from and against any and
all  costs  and  expenses incurred by the Lessee in the event the performance of
such  additional  work  causes  a  delay  in  the  return  of  the  Aircraft.

b.     Lessee  shall  perform  (or  have  performed  by  an  Agreed  Maintenance
Performer)  an internal and external corrosion inspection in accordance with the
manufacturer's  corrosion  prevention and control program ("CPCP") specified for
the  model  type  and  correct  any  discrepancies  in  accordance  with  the
recommendations  of  the  manufacturer  and the manufacturer's structural repair
manual  ("SRM").  In addition, all inspected areas will be properly treated with
corrosion  inhibitor  as  recommended  by  the  manufacturer.

c.     With  respect  to  the  Engines:

i.     Lessee shall perform a videotape borescope inspection of the low pressure
and  high  pressure  compressors and the turbine area of the Engines.  All items
beyond  the  applicable  Engine manufacturer's maintenance manual limits will be
rectified  at  Lessee's sole cost and expense.  No Engine will be "on watch" for
any  reason  requiring  special  or  out  of  sequence  inspection.

ii.     In  accordance  with  the  applicable manufacturer's maintenance manual,
Lessee  shall  perform a maximum power assurance run and condition, acceleration
and  bleed  valve  scheduling  checks on the Engines, and Lessee will record and
evaluate  the  Engine performance with Lessor and/or its representative entitled
to be present.  The performance and all operating parameters of each Engine will
be  within the limits specified in the Engine manufacturer's maintenance manual.

iii.     If  the Engine historical and technical records and the condition trend
monitoring  data  of any Engine or the APU indicate an abnormal acceleration (as
determined  with  reference to the applicable maintenance manual) in the rate of
deterioration  in  the  performance  of such Engine or APU, Lessee shall correct
such  conditions  causing  the  accelerated  rate  of  deterioration.

d.     Lessee  shall  remove  its  logo  and  exterior  markings.

12.3     Final  InspectionFinal  Inspection
         -----------------

a.     At  least  45 days before the redelivery of the Aircraft, the Lessee will
make available to the Lessor at its maintenance base (i) the Aircraft Documents,
(ii) a current and complete copy of the Agreed Maintenance Program, (iii) a copy
of  all  Engine  and  APU  trend  monitoring data, (iv) a written summary of all
sampling  programs  involving  or  affecting the Aircraft, and (v) a copy of all
other  documentation  and data reasonably requested by Lessor and required to be
maintained  by  FAR  Part  129  operators  for review and inspection in order to
prepare  for the Final Inspection of the Aircraft and in order to facilitate the
Aircraft's  integration into any subsequent operator's fleet.  The Lessor agrees
that  it will not disclose the contents of the Agreed Maintenance Program to any
Person  except  to  the extent necessary to monitor the Lessee's compliance with
this  Agreement  and/or  to bridge the maintenance program for the Aircraft from
the  Agreed  Maintenance  Program  to  another  program  after  the Expiry Date.

b.     During  the  30 days immediately prior to redelivery of the Aircraft, the
Lessee  will  make  the  Aircraft  available  to  the  Lessor  at  the  Lessee's
maintenance base for inspection (the "Final Inspection") in order to verify that
the  condition  of  the  Aircraft  complies  with  this  Agreement.

c.     At  the  request  of  Lessor, Lessee shall perform "bridging" maintenance
procedures  for  the  purpose  of  standardizing the Aircraft to the maintenance
program  of  any  subsequent  operator  of the Aircraft; provided, however, that
Lessor  shall  pay  to  Lessee  all  costs  and  expenses incurred by the Lessee
relating  to  the  "bridging"  procedures  and  the performance of such bridging
procedures  shall  not  materially disrupt Lessee's business or operations.  The
Lessor shall indemnify and hold harmless the Lessee from and against any and all
costs  and  expenses incurred by the Lessee in the event the performance of such
"bridging"  causes  a  delay  in  the  return  of  the  Aircraft.

d.     The  Lessor  shall  also be entitled, as part of the Final Inspection, to
require  the  Lessee  to  perform an acceptance flight of up to two hours (which
Lessee  may  perform  as part of the ferry flight to the Redelivery Location, if
any)  at  the Lessee's cost (with up to three of the Lessor's representatives as
on-board  observers)  and such further acceptance flights as may be necessary in
the  event that the first or subsequent flights do not confirm that the Aircraft
complies  with the requirements of this Agreement.  The Lessee's pilots shall be
in  control  of  such  acceptance  flights  at  all  times.

12.4.     Non-ComplianceNon-Compliance
          --------------

To  the  extent that, on the Expiry Date, the condition of the Aircraft does not
comply  with  this  Agreement,  the  Lessee  shall  at the option of the Lessor:

a.     immediately  rectify  the  non-compliance  and,  to  the  extent  the
non-compliance  extends  beyond  the Expiry Date due to acts or omissions of the
Lessee,  the  Term  will  be automatically extended until the non-compliance has
been  rectified;  or

b.     redeliver  the  Aircraft  to  the  Lessor  and  indemnify the Lessor, and
provide security reasonably acceptable to the Lessor for that indemnity, against
the  cost of putting the Aircraft into the condition required by this Agreement.

During any extension of the Term pursuant to sub-clause (a), this Agreement will
remain  in  full  force  and effect, including the obligation to pay rent (which
Lessee  shall pay at the rate of $4,271.00 per day weekly in arrears); provided,
however,  that  Lessee  shall  not  operate,  or  permit  others to operate, the
Aircraft  after the Expiry Date except for acceptance flights pursuant to Clause
12.2  and  a  ferry  flight  to  the  Redelivery  Location.

c.     The  Lessor  may  require  the Lessee to remove any Equipment Change that
would  diminish  or impair the value, utility, condition or airworthiness of the
Aircraft  and  to  restore the Aircraft to its condition prior to that Equipment
Change.

12.5.     Export  DocumentationExport  Documentation
          ---------------------

Upon  redelivery and upon request by the Lessor, the Lessee shall provide to the
Lessor  all  documents  necessary  to  export  the  Aircraft  from  the State of
Incorporation (including a valid and subsisting export license for the Aircraft,
if  any).

12.6.     AcknowledgmentAcknowledgment
          --------------

Provided the Lessee has complied with its obligations under this Agreement, upon
redelivery  of  the  Aircraft  by  the  Lessee  to  the Lessor at the Redelivery
Location,  the  Lessor  will  deliver  to  the  Lessee  a written acknowledgment
confirming  that  the  Lessor is satisfied that the Aircraft is in the condition
required  by this Agreement and has been redelivered to the Lessor in accordance
with  this  Agreement.  Within  one  (1)  Business  Day  of the delivery of such
acknowledgment  the  Lessor  shall return the balance, if any, of the Deposit to
Lessee,  plus  accrued  interest (if the Deposit was in cash) in accordance with
Clause  5.14,  and  shall  send  the letter of credit to the applicable bank for
cancellation.

          --------------------------

If  an Event of Default occurs, and for as long as it shall continue, the Lessor
may sell or otherwise deal with the Aircraft as if this Agreement had never been
made and the Lessee will, at the request of the Lessor, take all steps necessary
to return the Aircraft to Lessor, including if requested by Lessor to export the
Aircraft from the country where the Aircraft is for the time being situated, and
any other steps necessary to enable the Aircraft to be redelivered to the Lessor
in  accordance  with  this  Agreement.

13.4.     Default  PaymentsDefault  Payments
          -----------------

If  an  Event  of Default occurs, the Lessee will indemnify the Lessor on demand
against  any  loss,  damage,  expense,  cost  or  liability which the Lessor may
sustain  or  incur  directly  or  indirectly  as  a  result,  including:

a.     all unpaid Basic Rent and Supplemental Rent to and including the date the
Aircraft  is  returned  to  Lessor  (the  "Return  Date")  then  due and unpaid;

b.     if  the  Aircraft  is re-leased, the amount, if any, by which the present
value  of  the remaining Basic Rent due under this Lease, discounted at the rate
of  9.5%  per  annum  to  the Return Date ("PV Lease Rent"), exceeds the present
value of the periodic rent due under such re-lease commencing on the Return Date
and  continuing  for  the period that is co-extensive with the unexpired term of
this  Lease  or  such lesser period if the term of such re-lease is shorter than
such  unexpired  term, discounted to present value at the rate of 9.5% per annum
to  the  Return  Date;

c.     if the Aircraft is not re-leased or is sold, the amount, if any, by which
the  PV  Lease  Rent exceeds the present value of the fair market rent value for
the  Aircraft  as of the Return Date, discounted to present value at the rate of
9.5%  per  annum  to the Return Date; for purposes hereof, the "fair market rent
value"  of  the  Aircraft  shall be as specified in an appraisal by a recognized
independent  aircraft  appraiser  selected by Lessor and carried out pursuant to
prevailing  industry  standards  for  such  appraisals;

d.     any  amount of principal, interest, fees or other sums whatsoever paid or
payable  on account of funds borrowed in order to carry any amount unpaid by the
Lessee;

e.     any  loss,  premium,  penalty or expense that may be incurred in repaying
funds  raised to finance the Aircraft or in unwinding any swap, forward interest
rate agreement or other financial instrument relating in whole or in part to the
Lessor's  financing  of  the  Aircraft;  and

f.     any  loss,  cost,  expense  or  liability sustained or incurred by Lessor
owing  to  Lessee's  failure to redeliver the Aircraft on the date, at the place
and  in  the  condition  required  by  this  Agreement.

For  the avoidance of doubt, the provisions of Clause 5.9 will apply to any sums
payable  by  the  Lessee  pursuant  to  this  Clause  13.4.

of  this  Agreement,  each  reference  in  this  Agreement to the "Lessor" shall
thereafter  be  deemed  for  all  purposes  to  refer to the Transferee, and the
transferor  shall  be  relieved  of  all  obligations of the "Lessor" under this
Agreement  arising  after  the  time  of  such  Transfer  except  to  the extent

Agreement  on  the  Delivery  Date  with  the  same  force and effect as if such
Mortgagee  was  an  original  addressee  of  such  opinion  when  given;  and

f.     such  other  documents as Lessor or such Mortgagee may reasonably request
so  long  as such documents do not adversely affect the rights or obligations of

Clauses 14.2 and 14.3, Lessor shall be entitled to transfer its right, title and
interests  in and to the Aircraft to any Person and lease the Aircraft from such
Person  (a  "Head Lessor"), and in such event Lessor shall retain its rights and
obligations  as  the "Lessor" under this Agreement.  In the event of such a sale

entitled  to  grant  a Mortgage covering the Aircraft and this Agreement, (c) at
the sole cost and expense of Lessor, Lessee shall execute and deliver to Lessor,

Clauses  14.2(c)(i)  through  (vi)  and  Clauses  14.3(a) through (f) above, and
Lessee shall cooperate with Lessor to make such other changes to this Agreement,

"Indemnitees",  as  Lessor may reasonably request so long as such changes do not
adversely  affect  the  rights  or obligations of Lessee under this Agreement or
otherwise  adversely  affect  Lessee.

14.5.     Further  AcknowledgmentsFurther  Acknowledgments
          ------------------------

Lessor  to  agree  in  writing  with  the  Lessee that such Mortgagee's and Head
Lessor's  rights  in  and  to the Aircraft shall be subject to the terms of this
Agreement,  including  to  the  Lessee's rights to the quiet use, possession and
enjoyment provisions contained in this Agreement.  Prior to or at closing of any
financing  arrangement  pertaining to the Aircraft, the Lessee shall be entitled
to  receive  from  each  Lessor  Lender  a letter of quiet enjoyment in form and
substance  reasonably satisfactory to the Lessee.  Except as expressly set forth
in  this  Agreement,  no  Mortgage  or  Head  Lease  shall  increase  the
responsibilities,  obligations  or liabilities (including with respect to Taxes)
of  the  Lessee  or  deprive the Lessee of any of its rights or privileges under
this  Agreement  (including  the  right to register the Aircraft in the State of
Registration).  The  Lessor's obligations to perform the terms and conditions of
this  Agreement  shall  remain  in  full  force  and  effect notwithstanding the

enter  into  any  Head  Lease  that  violates  the  terms  of  this Clause 14.6.

shall be conclusive and may be enforced in any other jurisdiction by suit on the
judgment  or  as otherwise permitted by applicable law, a certified or true copy

indebtedness or liability of Lessor or Lessee.  Each of Lessor and Lessee hereby
irrevocably  waives  any  objection  which  it  may now or hereafter have to the
laying  of  venue in any suit, action or proceeding brought in any Agreed Court,

concerned.

operating  or  maintenance requirements on a terminating action basis as if such
waivers,  alternate  means  of  compliance,  dispensations or extensions did not
exist,  provided,  however,  if  such  waivers,  alternate  means of compliance,
        --------   -------
dispensations  or  extensions  are  generally  available  to  operators of MD-87
aircraft,  Lessor  shall  not  be  required  to  cause  the previous operator to
terminate  such  Airworthiness  Directives and/or other operating or maintenance

(i)     have  installed  the  full complement of Engines, which Engines shall be
Pratt & Whitney JT8D-219 Engines, and Parts and other equipment, accessories and
loose  equipment  as  would  remain installed in such Aircraft and shall be in a
condition  suitable  for  operation  in  commercial  service;  and

(ii)     comply  with  the  Manufacturer's  and  Engine  Manufacturer's original
specifications  therefor  and/or supported by relevant documentation approved by
the  Manufacturer  and  Engine  Manufacturer,  as  the  case  may  be;

(m)     the  Aircraft  shall  meet  the requirements of FAR Part 36, Appendix C,

the  Aircraft to Lessor by the previous operator, perform a borescope inspection
of  the  Engines  (hot  and  cold sections) and the APU.  Lessor shall cause all
items  beyond the applicable Engine Manufacturer's or APU manufacturer's, as the
case  may  be,  maintenance  manual  limits  to  be  rectified  at  the previous
operator's  sole  cost and expense.  No Engine will be "on watch" for any reason
requiring  special  or  out  of  sequence  inspection;

and  life-limited  components or Parts will have less than twelve (12) months or
2,000  Cycles  remaining  to  operate  pursuant  to  the  previous  operator's
Maintenance  Program.  In  the  event any of the hard time limit or life-limited
components  or  Parts will have less than the limits established in the previous
sentence, Lessee will replace such non-compliant components and Parts at the "C"
Check  immediately  after delivery of the Aircraft with compliant components and
Parts which Lessor shall supply, at its sole cost and expense (including cost of
the  components  and  Parts and shipment to the Lessee, but explicitly excluding
any  labor  cost),  and  Lessee  shall  immediately  return  the  exchanged,
non-compliant components and Parts to the previous operator at its Reno, Nevada,
location,  at  Lessor's  sole  cost  and  expense;

(r)     Lessor  shall provide to Lessee a list of all components or Parts of the
Aircraft  which  have  a calendar limit, and Lessor and Lessee will determine if

pursuant  to  the  previous operator's Maintenance Program at least one (1) year
from  the  Delivery Date, except that emergency equipment will have remaining to
operate at least six (6) months from the Delivery Date.  In the event any of the
calendar limit components or Parts will have less than the limits established in
the  previous  sentence,  Lessee  will replace such non-compliant components and
Parts  at  the  next  "C"  Check immediately after delivery of the Aircraft with
compliant  components  and Parts which Lessor shall supply, at its sole cost and
expense  (including cost of the components and Parts and shipment to the Lessee,
but  explicitly  excluding  any labor cost), and Lessee shall immediately return
the  exchanged,  non-compliant  components and Parts to the previous operator at
its  Reno,  Nevada,  location,  at  Lessor's  sole  cost  and  expense;

(s)     the  Aircraft  fluid  reservoirs  (including  oil, oxygen, hydraulic and
water)  will  be serviced to full and the waste tank serviced in accordance with
Manufacturer's  instructions;

(t)     all  technical  records  and  manuals  shall  be  up  to  date,  in form
reasonably  acceptable  to  Lessee  and  with  no  deferred  maintenance  items
outstanding  under  the previous operator's Maintenance Program, unless normally

that  are  more  than  the  number of Flight Hours that were remaining until the
scheduled  completion  of  a Complete Heavy Work Package as of the Delivery Date
(b)  multiplied  by  US$50.00;

For  the  avoidance  of  doubt,  any  amounts due to the Lessor pursuant to this

paragraphs  (b) or (d) of Schedule 10 and a payment made for the net amount due;

(h)     have  complied  with  all  airworthiness directives and mandatory orders
affecting  that  model  of  Aircraft  issued  by the Aviation Authority (and, if
different,  the  FAA)  that  are  required  terminating  action during the Term;

(i)     no  special  or  unique  manufacturer  inspection  or check requirements
specific  to  the  Aircraft  will  exist  unless  there is no terminating action
available  from  any  source;

engine  installed  at  Delivery) shall, to the extent not previously provided to
the  Lessor,  be  accompanied  by  all  documentation  the Lessor may require to
evidence  that title thereto is properly vested in the Lessor in accordance with
this  Agreement  and  will  have  at least 3,000 Cycles remaining until the next
scheduled  removal  for  engine  heavy  maintenance under the Agreed Maintenance
Program or removal of the most life limited part or known scheduled repair visit
under  the  Manufacturer's  maintenance  program.

(b)     On  the Expiry Date, the condition of each Engine shall be compared with
its  condition  on  the  Delivery  Date.  Then:
          (i)     Engines:
          (aa)     to the extent that, on the Expiry Date, there are more Cycles
since  the  last  off-wing  engine  (turbine,  not  section and compressor) full
restoration  based  on  an ESV2 under the manufacturer's maintenance program (an
"Engine  Refurbishment")  as  when  compared  with the condition of such Engines
since  the  last  Engine Refurbishment as of the Delivery Date, Lessee shall pay
compensation  to Lessor in an amount equal to US$80.00 multiplied by  the number
                                                       -------------
of  Cycles  in  the  difference;  or
          (bb)     to the extent that, on the Expiry Date, there are less Cycles
since  the last Engine Refurbishment as when compared with the condition of such
Engines  since  the  last  Engine  Refurbishment as of the Delivery Date, Lessor
shall  pay  compensation  to Lessee in an amount equal to US$80.00 multiplied by

Term  based  on  the then current Pratt & Whitney catalogue prices in accordance
with  the  following:
(aa)     to  the extent that, on the Expiry Date, there are more Cycles flown on
any  LLP  as  compared with the condition of such LLP on the Delivery Date, then
Lessee  shall  pay compensation to Lessor in an amount equal to the relevant LLP
cycle  cost  (defined  for  2000  in  Schedule  7  and  as  amended over time by
manufacturer's  price  list  and which in the aggregate for 2000 is US$38.00 per
Cycle)  multiplied  by  the  number  of  Cycles  in  the  difference;  or
        --------------
(bb)     to  the extent that, on the Expiry Date, there are less Cycles flown on
any  LLP  as  compared with the condition of such LLP on the Delivery Date, then
Lessor  shall  pay compensation to Lessee in an amount equal to the relevant LLP
cycle cost (defined as per (aa) above) multiplied by the number of Cycles in the
                                       -------------
difference.
     Lessor  shall  consent  to  the workscope for the last Engine shop visit in
order  to  avoid  a  situation where, on redelivery of the Aircraft, the Engines
would  have  a materially greater remaining life until overhaul than they had at
the  Delivery Date.      Upon any default by Lessor of its obligation to pay any
compensation due to Lessee pursuant to Clause 2(b)(i)(bb) or Clause 2(b)(ii)(bb)
of  this Schedule 5, Lessee shall have the right, at its expense, to remove from
the  Aircraft  the  Engine  or Engines (each such Engine so removed, a "Replaced
Engine")  giving  rise  to  such payment obligation and to replace such Replaced
Engine  with  an  engine  that complies with Clause 8.13(a) of the Agreement and
this  Schedule  5  (a
"Replacement Engine") in order to avoid or reduce the amount of the compensation
due  to  Lessee  hereunder.  Upon any such removal and replacement of a Replaced
Engine,  Lessee  shall  convey  or  cause  to be conveyed to Lessor title to the
Replacement  Engine,  free  and  clear  of  all  Security  Interests  other than
Permitted  Liens.  Prior  to or at the time of any such conveyance, Lessee shall
(i)  furnish  Lessor  with a bill of sale with respect to the Replacement Engine
and  (ii)  take  such  other  action  and  furnish  such  other certificates and
documents  as  Lessor  may  reasonably  require  in  order  to  ensure  that the
Replacement  Engine  is  duly  and  properly  conveyed  to  Lessor.  Upon  full
compliance  with  this  Clause 2(b), title to each Replaced Engine shall pass to
Lessee  in  accordance  with  Section  8.17(b)  of  the  Agreement;
(c)          have  no  defect that reduces the Cycles of remaining life pursuant
to  manufacturer's  or  airworthiness  requirements  until overhaul to less than
3,000;  and

(d)     be  in  a  condition that can operate at maximum rated take-off power at

shall  be  maintained  for  the  benefit of Lessor or its designee including any
Lessor  Lender.  Lessee  or  the  issuer of the LOC shall (i) renew or cause the
renewal  of  each  outstanding Letter of Credit on a timely basis as provided in
the  relevant LOC, (ii) if the bank that issued an outstanding LOC has indicated
its  intent  not  to  renew  such  LOC, provide either a substitute LOC or other

to  honor  Lessor's  properly  documented request to draw on an outstanding LOC,
provide for the benefit of Lessor and its designees either a substitute LOC that
is  issued  by  a bank acceptable to Lessor or other acceptable Deposit, in each
case  within  two  (2)  Business  Days  after  such  refusal.

(b)  Upon  the  occurrence of an LOC Default, Lessee agrees to deliver to Lessor
(or  any  applicable  Lessor Lender) either a substitute LOC or other acceptable
Deposit,  in each case on or before the second Business Day after the occurrence
thereof.  "LOC  Default"  shall  mean  with  respect  to an outstanding LOC, the
           ------------
occurrence  of  any  of  the following events:  (i) the issuer of such LOC shall
fail  to  maintain  an  unsecured  credit  rating of at least "AA" by Standard &
Poor's  Ratings  Services  or  "___" by Moody's Investor Service, Inc.; (ii) the
issuer  of  the  LOC  shall fail to comply with or perform its obligations under

grace  period; (iii) the issuer of such LOC shall disaffirm, disclaim, repudiate
or  reject,  in  whole  or in part, or challenge the validity of, such LOC; (iv)
such  LOC  shall expire or terminate, or shall fail or cease to be in full force
and  effect  at  any  time  during the term of this Agreement; or (v) any of the
events  of  the type specified in Clauses 13.1(g) or (h) of this Agreement shall
occur  with  respect  to  the  issuer  of  such  LOC.

(c)  (i)  A  LOC shall provide that Lessor or its designee may draw upon the LOC
in an amount that is equal to all amounts that are due and owing from Lessee but
have  not  been  paid  to Lessor within the time allowed for such payments under
this  Agreement.  A LOC shall provide that a drawing may be made on the LOC upon
submission  to the bank issuing the LOC of one or more certificates of Lessor in
accordance  with  the  specific  requirements  of  the  LOC.

(ii)  Upon or at any time after the occurrence of an Event of Default under this
Agreement, Lessor or its designee may draw on the entire, undrawn portion of any
outstanding  LOC  upon  submission  to  the bank issuing such LOC of one or more
certificates  in  accordance  with  the  specific requirements of the LOC.  Cash
proceeds received from drawing upon the LOC shall be deemed a cash Deposit until
applied  in  accordance with this Agreement. Notwithstanding Lessor's receipt of
cash  under  the  LOC,  Lessee  shall remain liable to Lessor for any failure to
maintain  a  sufficient  Deposit in accordance with the terms of this Agreement.
In  addition,  Lessee  shall  remain  liable for any amounts owing to Lessor and
remaining  unpaid  after  the  application  of  the  amounts so drawn by Lessor.

                      SCHEDULE 10 -- SUBSEQUENT INVESTMENTS

In  accordance with Clause 7.7, the Lessor shall make each applicable Subsequent
Investment,  as  follows:

(a)     reimburse  the  Lessee, within five (5) Business Days after the Delivery
Date  and  against  Lessee's invoice therefor, for four hundred thousand dollars
($400,000.00)  in  respect  of the "C" Check to be completed by Lessee after the
Delivery  Date;

(b)     reimburse  the  Lessee,  within  ten  (10)  Business Days after Lessor's
receipt  of  Lessee's  itemized  invoice, for all amounts reasonably incurred by
Lessee  for parts (but not for labor expense) necessary to correct discrepancies
from  the  delivery conditions specified in Exhibit 4 which are noted during the
Observation  Period  of  the  ferry  flight  of  the  Aircraft from the Delivery
Location to Mexico City International Airport and relate solely to the operation
of the Aircraft (and not to records or issues which would otherwise be corrected
during  a  periodical "C" check); provided, however, that the Lessor's liability
with  respect  to  the  Lessor  Contribution  shall not exceed two hundred fifty
thousand  dollars  ($250,000.00) and any excess shall be the sole responsibility
of  the  Lessee;

(c)     reimburse  the  Lessee,  within  ten  (10)  Business Days after Lessor's
receipt  of  Lessee's  itemized  invoice,  for  sixty  five percent (65%) of all
amounts  reasonably  incurred  by  Lessee  for  parts  and labor expense for any
modifications  made  promptly  following  Delivery  (the "Lessor Contribution");
provided,  however,  that  the  Lessor's  liability  with  respect to the Lessor
Contribution  shall  not exceed eight hundred thousand dollars ($800,000.00) and
any  excess  shall  be  the  sole  responsibility  of  the  Lessee;

(d)     if  the  Lessee  shall  have  caused  compliance  with  the  insulation
airworthiness  directive issued by the FAA on May 25, 2000 (the "Insulation AD")
to  have  been  duly  effected  during  the  Term,  or, if the Lessee shall have
exercised  the  extension option pursuant to Clause 5.3, during the extension of
the  Term,  reimburse  the  Lessee, within ten (10) Business Days after Lessor's
receipt  of  Lessee's  invoice  together  with  any  supporting  documentation
reasonably requested by Lessor (which invoice and supporting documentation shall
in no event be tendered or delivered to the Lessor for payment prior to the date
which  is  eighteen (18) months after the Delivery Date), for the sum of (i) one
hundred  percent  (100%) of its cost with no markups for parts and labor expense
for  performance  of  the Insulation AD, and (ii) sixty six percent (66%) of the
Basic  Rent  for  the  month  of  the  Term  during  which  the Insulation AD is
completed;  provided,  however,  that the Lessor's liability with respect to the
cost  of  the  Insulation  AD  shall  not  exceed three hundred thousand dollars
($300,000.00) (exclusive or any rent abatement or reimbursement), and any excess
shall  be  the  sole  responsibility  of  the  Lessee;

(e)     if  (i)  the  Aircraft  shall be subject to any mandatory manufacturer's
service  bulletin  or FAA airworthiness directive (other that the Insulation AD)
which  requires  compliance  during  the Term, (ii) the Lessee shall have caused
compliance  with  such  service bulletin or airworthiness directive to have been
duly effected, and (iii) the Lessee's parts and labor expense for performance of
such  service  bulletin  or  airworthiness  directive  shall have exceeded fifty
thousand  dollars  ($50,000.00),  reimburse the Lessee, within ten (10) Business
                                  ---------------------
Days  after  Lessor's  receipt  of Lessee's invoice together with any supporting
documentation  reasonably  requested  by  Lessor,  for the prorated value of the
remaining  useful  life of the resulting improvement determined as follows.  The
first  fifty  thousand  dollars  ($50,000.00)  of  such expense for each service
bulletin  or  airworthiness  directive  shall  be the sole responsibility of the
Lessee.  Any  excess  shall  be  prorated,  with  the  Lessee's  liability being
determined  by  multiplying  the  excess  by  the  quotient  resulting  from the
following  formula:
            R
- -------------
120  -  (Term  -  R)
(with R equal to the number of months remaining in the Term after the completion
of  all  conditions  for  such reimbursement) and with the balance being the pro
rata  amount  due  from  the  Lessor;  and

(f)     upon  the  return  of  the Aircraft and the due performance of all other
obligations  due  in  connection  with  such  return  in  accordance  with  this
Agreement,  pay  to  the  Lessee,  within  ten (10) Business Days after Lessor's
receipt  of  Lessee's  invoice  together  with  any  supporting  documentation
reasonably  requested  by  Lessor,  one hundred percent (100%) of any Redelivery
Credit;  provided, however, that the Lessor shall have no liability with respect
to any Redelivery Credit relating to the Engines except to the extent either (i)
such  liability  has  been  generated  as  a  result  of  regularly scheduled or
otherwise  required  maintenance  work  performed on any Engine under the Agreed
Maintenance  Program, or (ii) Lessor (and if so required, any Lessor Lender) has
consented  in  writing  (with  such  consent  not to be unreasonably withheld or
delayed)  the  work scope of any heavy maintenance performed on the Engines (and
any  other  or  excess  maintenance  shall not be eligible for any such credit).
Lessee agrees that such consent may properly be refused if in the non-consenting
party's  sole  judgment  it  appears  that  the probable result would be that on
return  of  the  Aircraft  the Engines would have a materially greater remaining
life  until  overhaul  than  they  had  on  the  Delivery  Date.

Lessee  shall  give prompt notice to Lessor of any mandatory service bulletin or
airworthiness  directive  for  which  Lessor  is reasonably expected to have any
liability  pursuant  to  this  Schedule  10 or Clause 7.7.  Additionally, in the
event that the Lessor's aggregate liability under this Agreement with respect to
mandatory  service bulletins and airworthiness directives is reasonably expected
to  exceed  one million dollars ($1,000,000.00), Lessee shall give Lessor prompt
notice thereof and Lessor shall thereafter have the option to terminate the Term
on  not  less  than  one  hundred eighty (180) days' notice to Lessee; provided,
however,  that  Lessor shall have no such termination option if Lessee agrees in
such  notice  to  bear  all  costs  relating  to  such  service  bulletins  and
airworthiness  directives  from  and after the point at which Lessor's aggregate
liability  under  this  Agreement  with  respect  to  service  bulletins  and
airworthiness  directives  is  equal  to  one  million  dollars ($1,000,000.00).

Any  amounts due to Lessee pursuant to paragraphs (d) or (f) of this Schedule 10
may  be set off against any amounts due to the Lessor pursuant to Schedule 5 and
a  payment  made  for  the  net  amount  due.
