           Sublessee  that at Delivery the Aircraft  will be  substantially  and
           materially  in the  condition  set forth in Schedule 4, provided that
           this confirmation expires as at Delivery.

           (2) observers on board the Aircraft during delivery acceptance flight
           from  Sublessor.  Sublessee  acknowledges  that,  as  between  it and

           inspection  and knowledge of the Aircraft in  determining  whether it
           meets the requirements of this Agreement.

4.4        Delivery of Aircraft to Sublessee

           Sublessor  will  deliver the  Aircraft to  Sublessee  at the Delivery
           Location.  Provided that the Aircraft is in the condition required by
           Clause  4.2,  upon  the  tender  of  the  Aircraft  by  Sublessor  to
           Sublessee,  Sublessee will accept the Aircraft and the date of tender
           by Sublessor to Sublessee  will be deemed to be the Delivery Date for
           all purposes under this Agreement, including, but not limited to, the
           commencement  of  Sublessee's   obligation  to  pay  Rent  hereunder.
           Sublessee  shall execute and deliver the  Acceptance  Certificate  to
           Sublessor on the Delivery Date.

4.5        Sublessee's Failure to take Delivery

           If  Sublessee  fails to (i) comply with the  conditions  contained in
           Clauses 3.1 so as to allow Delivery to take place upon tender or (ii)
           take delivery of the Aircraft when properly  tendered for Delivery by
           Sublessor  in  the  condition  required  hereunder,   Sublessee  will
           indemnify   Sublessor  for  all  costs  and  expenses,   directly  or
           indirectly,  incurred by Sublessor as a result thereof including (but
           without  limitation)  any payments  that  Sublessor,  or  Sublessor's
           General  Partner,  affiliates or related  companies become obliged to
           make to any third  party to put the  Aircraft  in the  condition  set
           forth in Schedule 4.

           amount of the Security Deposit, if paid, and will return  the  Letter
           of Credit. If either party does not give notice of termination within

           of the Security  Deposit with its general  funds and that no interest

           amount from the  Maintenance  Reserves  not paid in cash by Sublessee
           and, subject to Clause 9.6, any remaining balances of the Maintenance

           outstanding  invoice will be submitted  after the Expiry Date and the
           anticipated amount of such invoice. So long as Sublessee has provided
           such notice to Sublessor,  Sublessee may then submit such outstanding
           invoice at any time within  three (3) months  after the Expiry  Date;
           provided,  however,  if  Sublessee  contests  any  such  invoice  and
           provides  Sublessor with notice of such contest and periodic  updates
           of the progress of such contest,  the time for  submitting an invoice

                        nature of the Aircraft for any  particular use or trade,
                        or for registration or  documentation  under the laws of

                        terminating  or in any way affecting  any  obligation of
                        Sublessee under this Agreement.

10.4       Application of Payments to Sublessor

           If any sum paid to  Sublessor or recovered by Sublessor in respect of
           the  liabilities  of Sublessee  under this Agreement is less than the
           amount  then due,  Sublessor  may apply that sum to amounts due under
           this  Agreement in such  proportions  and order and generally in such
           manner as Sublessor may determine.

10.5       Currency Indemnity

           If under any applicable law, whether as a result of judgement against
           Sublessee or the  liquidation  of Sublessee or for any other  reason,
           any payment under or in connection  with this Agreement is made or is
           recovered in a currency ("other currency") other than the currency in
           which  it  is  payable  pursuant  to  this  Agreement   ("contractual
           currency"),  Sublessee  shall,  to the extent that the payment  (when
           converted  into the  contractual  currency at the rate of exchange on
           such date or, in the case of a  liquidation,  the latest date for the
           determination  of liabilities  permitted by the applicable law) falls
           short of the amount payable under this  Agreement,  as a separate and
           independent obligation,  fully indemnify Sublessor against the amount
           of the  shortfall.  For the  purposes  of this  sub-Clause  "rate  of
           exchange"  means  the  rate at  which  the  Sublessor  is able on the
           relevant date to purchase the  contractual  currency in London or any
           other place Sublessor may reasonably choose with the other currency.

10.6       Set-off

           Sublessor may set-off any matured  obligation owed by Sublessee under
           the  Transaction  Documents  or  any  Other  Agreements  against  any
           obligation, whether or not matured, owed by Sublessor to Sublessee.

10.7       Time for Payments

           If any payment due under this Agreement  other than a payment of Rent
           (see  Clause  7.4)  would  otherwise  be due on a day  that  is not a
           Business Day, it shall be due on the next succeeding Business Day.

11.        SUBLESSOR'S COVENANTS

11.1       Quiet Enjoyment



<PAGE>


           Provided no Default has occurred and is continuing,  Sublessor  shall
           not,  and no one  claiming  by or through  the acts or  omissions  of
           Sublessor  or Owner  Trustee  shall,  interfere  with the quiet  use,
           possession  and  enjoyment of the  Aircraft by  Sublessee  during the
           Sublease Term. Sublessor will cause Lender to confirm,  substantially
           in the  form  of  Schedule  11 or  such  other  form  as  Lender  may
           reasonably  require,  that it will not interfere  with the quiet use,
           possession  and  enjoyment of the  Aircraft by  Sublessee  during the
           Sublease Term, provided no Default has occurred and is continuing.

11.2       Sublessor Obligations Following Expiry Date

           Within five (5) Business Days after:

           (i)          redelivery of the Aircraft to  Sublessor  in  accordance
                        with and in the condition required by this Agreement; or

           (ii)         payment  received  by  Sublessor  of  the  Agreed  Value
                        following a Total Loss after the Delivery Date;

           or in each case such later time as Sublessor is reasonably  satisfied
           that Sublessee has irrevocably paid to Sublessor all amounts that may
           then be outstanding or become payable under the Transaction Documents
           and the Other  Agreements,  Sublessor shall (provided that no Default
           has occurred and is continuing):

                        (a)        pay  to  Sublessee  an  amount  equal  to the
                                   balance of the Security Deposit, if any, paid
                                   by Sublessee  under this  Agreement  and then
                                   held by Sublessor; and

                        (b)        pay to  Sublessee  the  amount  of  any  Rent
                                   received  in respect  of any  period  falling
                                   after  the  Redelivery  Date  or the  date of
                                   payment of the Agreed Value,  as the case may
                                   be; provided,  however, if there is a dispute
                                   between  Sublessor  and  Sublessee  as to the
                                   amount  due  to  Sublessee,  Sublessor  shall
                                   nevertheless  pay to Sublessee such amount as
                                   in Sublessor's reasonable judgement is not in
                                   dispute   or  is  in  excess  of  the  amount
                                   Sublessor's claim is due; and

                        (c)        return the Letter of Credit.

                        Threshold;


<PAGE>



           (ii)         of any suit, arbitration or proceeding before any court,
                        administrative  agency or Government  Entity  which,  if
                        adversely determined,  would materially adversely affect
                        Sublessee's financial condition,  affairs, operations or
                        its ability to perform under this Agreement;

           (iii)        of any Total Loss to the  Aircraft or any damage  caused

                        vendors)  that is material to the business and operation
                        of  Sublessee  will  not  be  year  2000  compliant  (as
                        described  in  Clause  2.1  (xxii))  on a timely  basis,
                        except  to  the  extent  that  such  failure  could  not
                        reasonably  be  expected  to have a  materially  adverse
                        effect.

12.3       Sublessor Visits

           Sublessor may visit, upon reasonable notice,  Sublessee's premises to

           Sublessee  will,  within  ten (10)  Business  Days  after  receipt of

           deliver to Sublessor a written statement as to each of the following:


<PAGE>


           (i)          certifying that this Agreement is unmodified and in full
                        force and effect (or, if modified, stating the nature of
                        such modification and certifying that this Agreement, as
                        so  modified,  is in full force and effect) and the date
                        to which the Rent and other charges are paid in advance,
                        if any;

           (ii)         acknowledging   that  there  are  not,  to   Sublessee's
                        knowledge, any uncured defaults on the part of Sublessor
                        hereunder,  or specifying such defaults if there are any
                        claimed by Sublessee; and

           (iii)        acknowledging  that  Sublessee  has  no  claims  against
                        Sublessor by reason of the  condition of the Aircraft as
                        of the Delivery  Date or arising  subsequent  thereto to
                        the date of such statement.

           If Sublessee does not deliver such statement  within such time-limit,
           the  statements  set forth in this Clause 12.4 will be deemed correct
           and binding upon Sublessee.

12.5       Airport and Navigation Charges

12.5.1     Sublessee  will  promptly pay and discharge when due all landing fees
           and other similar  Airport Charges  imposed by the authorities of any
           airport  from or to which the Aircraft  may  operate  and any charges
           (including without limitation, all Air Navigation Charges) imposed by
           virtue of any regulations made by any relevant authority or any other
           charges in respect of air navigation incurred,in each case in respect
           of all aircraft of which it is the  operator,  and will indemnify and
           hold harmless  Sublessor in respect of the same.  This indemnity will
           continue in full force and effect  notwithstanding the termination or
           expiration  of this  Agreement.  Sublessee  will ensure that all such
           charges are paid on a regular  basis and that invoices  are  received
           (and,  if not  received,  are  specifically requested) by it from the
           relevant authorities no more than three (3) months after the event to
           which the charges relate.

12.5.2     If requested by Sublessor,  Sublessee  will provide  Sublessor with a
           list of the  airports  to which the  Aircraft  or  Sublessee's  other
           aircraft are regularly  operated.  Sublessee  hereby  authorises  any
           Aviation Authority, any airport or any other creditor claiming rights
           on the Aircraft or  Sublessee's  other aircraft to confirm the status
           of  Sublessee's  payments to such  creditor  for the Aircraft and its
           other aircraft, as and when requested by Sublessor.  To evidence this
           authority,  Sublessee will at Sublessor's request execute one or more
           authorities substantially in the form of Schedule 7.



<PAGE>


12.6       Operation of Aircraft

           Sublessee  shall  not  maintain,  use  or  operate  the  Aircraft  in
           violation of any law or any  mandatory  rule,  regulation or order of
           any  Government  Entity having  jurisdiction  in any country,  state,
           province or other political subdivision in or over which the Aircraft
           is flown or in violation of any airworthiness certificate, license or
           registration   relating  to  the  Aircraft  issued  by  the  Aviation
           Authority  or any similar  authority or any  jurisdiction  in or over
           which the Aircraft is flown.  If any such law,  rule,  regulation  or
           order requires alteration of the Aircraft, Sublessee shall conform or
           procure  conformance  thereto  at its own  expense  and  maintain  or
           procure  maintenance  of the Aircraft in proper  operating  condition
           under  such  laws,  rules,  regulations  and  orders;  provided  that
           Sublessee may in good faith  contest,  or procure the contest of, the
           validity or application of any such law, rule, regulation or order in
           any reasonable manner that does not adversely affect Sublessor or its
           interest in the Aircraft.  In particular,  Sublessee will ensure that
           the  Aircraft at all times  during the  Sublease  Term is operated by
           duly  qualified  pilots  and  aircrew  employees,  and is not used to
           transport  contraband  or illegal  narcotics or hazardous or perilous
           cargo   (other   than   pursuant  to   applicable   FAA  and  carrier
           regulations).  The  Aircraft  may be used or  operated in flight crew
           conversion,   training  for   Sublessee's   own   employees  and  for
           experimental flights;  provided,  however,  prior to any such flights
           Sublessee  shall  notify  Sublessor  and shall  deliver to  Sublessor
           evidence that insurance coverage is in effect for such flights.

           Sublessee  shall not operate or locate the  Airframe or any Engine or
           Part or suffer the  Airframe  or any Engine or Part to be operated or
           located (i) in any area, or for carriage of any goods,  excluded from

           Sublessor may at all reasonable  times on reasonable  notice inspect,
           or appoint an inspector  (including Lender) on its behalf to inspect,
           the  Aircraft  or any part  thereof,  provided  that if no Default or
           Event of Default has occurred and is continuing  Sublessee  shall not
           be obliged hereunder to permit,  or procure  permission for, any such
           inspection  that would result in an  unreasonable  disruption  of the
           operation  of the  Aircraft  or the  operation  of  the  business  of
           Sublessee  as  an  airline.   Sublessee   agrees  to  reimburse   the
           out-of-pocket  expenses  of  Sublessor  incurred  in making  any such

           provided that Sublessee shall in all cases pay or reimburse Sublessor
           for the costs of such  inspection  or survey if Sublessor is required

           limitations  herein  contained,  Sublessor and any inspector may gain
           access to the Aircraft,  including the Aircraft Documents.  Sublessee

           cost and expense of Sublessee,  itself arrange for such repairs to be
           carried  out.  Sublessee  shall on  demand  reimburse  the  costs and
           expenses incurred by Sublessor in effecting such repairs.

           the  Mortgage,  free  and  clear  of all  Security  Interests  except
           Permitted  Liens and shall,  except as  otherwise  provided in Clause

           assuming  such  replaced  Parts  were  in the  condition  and  repair
           required  to be  maintained  by the terms  hereof,  and shall  have a
           current "serviceable tag" of the manufacturer or maintenance facility
           providing such items to Sublessee.

16.2       Title to Replacement Parts

           All Parts at any time  removed  from the Airframe or any Engine shall
           remain the property of Owner Trustee and subject to the terms of this
           Agreement,  no matter  where  located,  until such time as such Parts
           shall be replaced by Parts that have been  incorporated  or installed
           in or attached or added to the  Airframe or Engine and which meet the
           requirements for replacement Parts specified above.  Immediately upon

           attached or added to the  Airframe  or any Engine as above  provided,
           without  further act, (a) title to the replaced Part shall  thereupon
           vest in  Sublessee,  shall cease to be subject to this  Agreement and
           shall no  longer  be  deemed a Part  hereunder  and (b) title to such
           replacement  Part  shall  pass  to  Owner  Trustee,  subject  to  the
           Mortgage,  free and clear of all Security  Interests except Permitted
           Liens  and  such  replacement  Part  shall  become  subject  to  this
           Agreement  and be  deemed  Part of the  Airframe  or  Engine  for all
           purposes   hereof  to  the  same  extent  as  the  Parts   originally
           incorporated or installed in or attached or added to such Airframe or
           Engine and shall become a Part hereunder.

16.3       Pooling of Parts



<PAGE>


           Any Part  removed  from the  Airframe  or any Engine as  provided  in
           Clause 16.1 or 16.2 may be subjected to a normal pooling  arrangement
           customary in the airline industry entered into in the ordinary course
           of  Sublessee's  business,  provided  that  the part  replacing  such
           removed Part shall be incorporated or installed in or attached to the
           Airframe  or such Engine in  accordance  with Clause 16.1 and 16.2 as
           soon as practicable  after the removal of such removed Part.  Without
           prejudice  to  the   generality  of  the  foregoing   sentence,   any
           replacement Part when incorporated or installed in or attached to the
           Airframe or any Engine may be owned by a third person subject to such
           a normal pooling  arrangement,  provided that  Sublessee,  at its own
           expense, as promptly thereafter as possible,  either (a) causes title
           to such  replacement Part to vest in Owner Trustee in accordance with
           Clause 16.1 and 16.2 free and clear of all Security  Interests except
           Permitted  Liens, or (b) replaces or procures the replacement of such
           replacement   Part  by  the   incorporation  or  installation  in  or
           attachment to such Airframe or Engine of a further  replacement  Part
           (which  meets the  requirements  of this Clause 16) free and clear of
           all Security Interests except Permitted Liens and by causing title to
           such further  replacement Part to vest in the Owner Trustee,  subject
           to the  Mortgage,  in  accordance  with Clause 16.1 and 16.2 and such
           further  replacement  Part  shall  forthwith  be  deemed  Part of the
           Airframe  or  Engine  to  the  same  extent  as the  Part  originally
           incorporated  or  installed  in or attached  to the  Airframe or such
           Engine and shall become a Part hereunder.

16.4       Alterations

           Sublessee  shall at its own expense,  make, or procure the making of,
           such  alterations and  modifications in and additions to the Airframe

           standards of the Aviation  Authority or any Government  Entity having
           jurisdiction  in  any  country,  state,  county  or  other  political
           subdivision in or over which the Aircraft is flown or the FAA and any
           mandatory or recommended  service bulletins of the  Manufacturer.  In
           addition, Sublessee may, at its own expense, from time to time, make,

           additions including the making of any improvements to the Airframe or
           any Engine as Sublessee may deem  desirable in the proper  conduct of
           its  business,  including,  removal  of Parts (for  purposes  of this
           Clause 16.4,  Obsolete  Parts) which  Sublessee  deems obsolete or no
           longer  suitable  or  appropriate  for  use in the  Airframe  or such
           Engine, provided that no such alteration,  modification,  addition or
           removal shall cost over US$ 200,000,  or alter the fundamental nature
           of the  Aircraft  as a  passenger  carrying  aircraft,  or change its
           original type design or  configuration,  or  materially  diminish the
           value or utility of the  Airframe or any such  Engine,  or impair the
           condition  or  airworthiness   thereof,  below  the  value,  utility,
           condition  and  airworthiness   thereof  immediately  prior  to  such
           alteration,  modification, addition or removal assuming such Airframe
           or  Engine  was  then in the  condition  and  repair  required  to be
           maintained  by the  terms  of  this  Agreement.  Title  to all  Parts
           incorporated  or installed in or attached or added to the Airframe or
           any such  Engine as the result of such  alteration,  modification  or
           addition shall be vested in Owner  Trustee,  subject to the Mortgage,
           and shall  forthwith  be deemed Part of the  Airframe or such Engine.
           Neither Owner Trustee,  Lender nor Sublessor  shall be required under
           any circumstances to pay directly for any alteration, modification or
           addition  to the  Aircraft  or to  reimburse  Sublessee  for the cost
           thereof.  Any other alterations other than those permitted  according
           to Clause 16.5  require  Sublessor's  prior  written  consent,  which
           consent shall not be unreasonably withheld or delayed.

16.5       Removal of Parts



<PAGE>


           Notwithstanding  the  foregoing,  so long as no  Default  shall  have
           occurred  and be  continuing,  Sublessee  may  remove,  or permit the
           removal of, at any time during the Sublease Term, any Part,  provided
           that (a) such Part is in addition  to, and not in  replacement  of or
           substitution for, any Part originally incorporated or installed in or
           attached to the  Airframe or any Engine at the time of Delivery or in
           replacement of, or substitution  for, any such Part, (b) such Part is
           not required to be  incorporated or installed in or attached or added
           to the  Airframe or such Engine  pursuant to the terms of Clause 16.4
           or 16.5,  and (c) such Part can be removed  from the Airframe or such
           Engine without causing damage to the Airframe or such Engine or if it
           causes any such damage is to be repaired and promptly  thereafter  is
           repaired and without  diminishing  or impairing  the value,  utility,
           condition or airworthiness  required to be maintained by the terms of
           this  Agreement  that the  Airframe or such Engine  would have had at
           such time had such alteration,  modification or addition not occurred
           assuming it was in the condition and repair required to be maintained
           under this Agreement. Upon the removal of any Part as provided in the
           immediately  preceding sentence and the removal of any Obsolete Part,
           title thereto shall, without further act, vest in Sublessee, free and
           clear of all rights of Owner  Trustee,  Lender and Sublessor and such
           Part shall no longer be deemed  part of the  Airframe  or Engine from
           which it was  removed.  Any  Part not so  removed  shall  remain  the
           property of Owner Trustee, subject to the Mortgage.

16.6       Substitution of Engine

           In addition to its rights under Clause 13,  Sublessee  shall have the
           right at its option at any time,  on at least  thirty (30) days prior
           written notice to Owner Trustee,  Lender and Sublessor, to substitute
           or procure the  substitution  of an engine of the same make and model
           as the Engine  specified  in  Schedule 1 or an engine of an  improved
           model suitable for  installation and use on the Airframe for any such
           Engine not then  installed or held for use on the Airframe.  Any such
           substitute  engine,  the  substitution of which is in accordance with
           the  provisions  of this  Clause  16.6 and  which  complies  with the
           requirements  of  this  Clause  16.6  being  a  "Replacement  Engine"
           provided  that  title to the  Replacement  Engine  shall be vested in
           Owner  Trustee,  subject  to the  Mortgage,  free  and  clear  of all
           Security  Interests,  other than Permitted Liens, and the Replacement
           Engine  shall  have a  value  and  utility  and  maintenance  status,
           including time since last Engine  Performance  Restoration  Visit, at
           least equal to the replaced Engine and time since new no greater than
           the replaced Engine as reasonably  determined by Sublessor,  assuming
           that such  Engine  was in the  condition  and repair  required  to be
           maintained by the terms of this Agreement and Sublessee shall deliver
           such documents  including a bill of sale and opinion of counsel as to
           title and  recordation  with the FAA,  as  Sublessor  may  reasonably
           request to evidence the foregoing.  In such event,  immediately  upon
           the  effectiveness of such substitution on the date set forth in such
           notice and without further act:

           (i)          title  to  the  replaced Engine  shall thereupon vest in
                        Sublessee free and clear of all rights of Owner Trustee,
                        Lender and Sublessor,  and  the  replaced  Engine  shall
                        cease  to  be  subject  to  this Agreement  and shall no
                        longer be deemed an Engine hereunder; and

           (ii)         title to such  Replacement  Engine  shall  vest in Owner
                        Trustee,  subject to the Mortgage, free and clear of all
                        Security  Interests  except  Permitted  Liens  and  such
                        Replacement   Engine  shall   become   subject  to  this
                        Agreement and an Engine  hereunder and be deemed part of
                        the Aircraft for all purposes hereof.

16.7       Temporary Removal of Parts

           Sublessee  shall  be  entitled,  so long  as no  Default  shall  have
           occurred  which has not been  remedied  or  waived to the  reasonable
           satisfaction of Sublessor,  to substitute,  replace or renew any Part
           with a part that does not satisfy the  requirements of Clause 16.1 or
           16.2 provided that:

           (i)          there shall not have been available to Sublessee, at the
                        time  and  in  the  place   that  such   substitute   or
                        replacement  part was  required to be  installed  on the
                        Airframe or Engines a  substitute  or  replacement  part
                        complying with the requirements of Clause 16.1 and 16.2;

           (ii)         it would have resulted in an unreasonable  disruption of
                        the  operation  of  the  Aircraft  or  the  business  of
                        Sublessee  as an airline to have  grounded  the Aircraft
                        until  such time as a  substitute  or  replacement  part
                        complying with the  requirements of Clause 16.1 and 16.2
                        became available for installation in or on the Aircraft;

           (iii)        Sublessee shall have notified  Sublessor prior to or, in
                        the  case of an  extreme  urgency  as  soon as  possible
                        after, the making of such  substitution,  replacement or
                        renewal of any material Part; and

           (iv)         as soon as possible after installation of the same in or
                        on the  Airframe  or  Engine  (and in any event no later
                        than  fifteen  (15)  days  thereafter)  Sublessee  shall
                        remove any such part not complying with the requirements
                        of Clause  16.1 and 16.2 and replace or  substitute  the
                        same with a Part complying with such requirements.

16.8       Parts Incapable of Transfer



<PAGE>


           If any  replacement  Part is  incapable  of becoming  the property of
           Owner Trustee free of all Security  Interests  (other than  Permitted
           Liens) as required by Clause 16 the part which it has replaced shall,
           unless  Sublessor  shall  otherwise  agree  in  writing,  be kept and
           maintained by the Sublessee or any sub-sublessee, as the case may be,
           until the Expiry Date and be placed on the  Aircraft in good  working
           order  before the  Aircraft is  redelivered  to the  Sublessor on the
           Expiry Date.

17.        MANUFACTURER'S WARRANTIES

17.1       Authorization

17.1.1     With  effect  from  Delivery,   Sublessor  authorises   Sublessee  to
           exercise such rights  as  Sublessor  may  have  in  relation  to  any
           warranty with respect to the  Aircraft, any Engine or any  Part  made
           by any manufacturer, vendor, subcontractor,  maintenance facility  or
           supplier subject to Sublessee  notifying  Sublessor in writing of any
           warranty  claim  of  a  material  nature   and    keeping   Sublessor
           continuously informed of the development of  such warranty  claim. To
           the extent that the same may not be available to Sublessee, Sublessor
           agrees to, at the sole cost and  expense  of  Sublessee, enforce such
           rights as Sublessor may have with respect  thereto for the benefit of
           Sublessee. Sublessor shall also have the right, rather than enforcing
           or making  such claim on behalf of Sublessee  under such  warranties,
           to appoint Sublessee  as its  agent  for such  purpose,  and in  such
           instance, Sublessee  agrees to accept such  appointment and make such
           claims and enforce  such   warranties   at its sole cost and expense.
           This authorization shall cease on the  Expiry  Date.  Sublessee shall
           not be entitled to  exercise its  authorisation   hereunder  while  a
           Default is continuing  (during  which  time  all  such  rights  shall
           revert to Sublessor  and  Sublessor  hereby  agrees to exercise and
           enforce such rights  during such period). 17.1.2 Sublessee shall give
           Sublessor prompt written notice of any warranty claim that is settled
           with Sublessee on the basis of a total or partial cash  payment.  Any
           cash payments shall be  applied to remedy the defect subject  to such
           warranty claim unless  Sublessor  otherwise  consents in writing. Any
           cash payments to Sublessee in respect of warranty claims that (either
           with  Sublessor's  written  consent or  because the defect can not be
           remedied)  are not applied  to the repair or remedy of defects in the
           Aircraft or to  compensate Sublessee  for the costs  incurred for any
           such  repair or remedy, and which are not in respect of  compensation
           for loss of use  of  the  Aircraft,  an  Engine  or Part  during  the
           Sublease Term due  to  a  defect  covered  by  such  warranty,  shall
           be for Sublessor's account.

17.2       Proceeds



<PAGE>


           So long as no  Default  has  occurred  and is  continuing,  Sublessor
           agrees, subject to Clause 17.1, to co-operate with Sublessee to cause
           any proceeds from any warranty  referred to in Clause 17.1 to be paid
           directly to Sublessee, and, if any such proceeds are nonetheless paid
           to  Sublessor,  Sublessor  agrees to remit  promptly such proceeds to
           Sublessee.  However,  while a Default is  continuing,  Sublessor  may
           immediately:

           (i)          retain for its own account any such proceeds  previously
                        paid to  Sublessorwhich  would  have  been  remitted  to
                        Sublessee  under this Clause 17.2 in the absence of such
                        Default or Event of Default; and

           (ii)         cause any proceeds of any pending claims to be  paid  to
                        Sublessor, rather than to Sublessee.

           Once the Default is cured, Sublessor shall reimburse Sublessee to the
           extent that it would have been  obliged to under this Clause 17.2 had
           no such Default occurred.

17.3       Agreements with Manufacturers

           To the extent that any  warranties  relating to the Aircraft are made
           available  under  an  agreement  between  any  manufacturer,  vendor,
           subcontractor or supplier and Sublessee, Sublessee will:

           (i)          apply the  proceeds of any claim under such agreement in
                        accordance with Clause 17.2; and

           (ii)         take all such steps as are  necessary  at the end of the
                        Sublease Term to ensure that the benefit of any of those
                        warranties that have not expired is vested in Sublessor.

17.4       No Operation Contrary to Warranties

           Sublessee shall not operate the Aircraft contrary to the terms of any
           warranty  referred to in Clause  17.1.1,  provided that Sublessor has
           advised Sublessee of the terms of such warranties.

18.7       Sublessee Examination of Aircraft

           DELIVERY BY SUBLESSEE TO SUBLESSOR OF THE  ACCEPTANCE  CERTIFICATE IS
           CONCLUSIVE PROOF AS BETWEEN  SUBLESSOR AND SUBLESSEE THAT SUBLESSEE'S
           TECHNICAL EXPERTS HAD EXAMINED AND INVESTIGATED THE AIRCRAFT, ENGINES
           AND EACH PART THEREOF AND DETERMINED  THAT (i) EACH WAS AIRWORTHY AND

           omission or the active or passive  negligence  of  Sublessor or Owner
           Trustee or their agents or representatives excepting only Sublessor's
           or Owner  Trustee or their  respective  agents'  or  representatives'
           gross negligence or wilful misconduct.

18.9       Exclusion

                        otherwise)  caused or alleged to be caused  directly  or
                        indirectly  by  the  Aircraft  or any  Engine  or by any
                        inadequacy thereof or deficiency or defect therein or by
                        any other circumstance in connection therewith;

           (ii)         the use, operation or performance of the Aircraft or any
                        risks relating thereto;

           (iii)        any  interruption  of  service,   loss  of  business  or
                        anticipated  profits or any other  direct,  indirect  or
                        consequential loss or damage; or

           (iv)         the delivery, operation, servicing, maintenance, repair,
                        improvement or  replacement of the Aircraft,  any Engine
                        or any Part except as otherwise expressly provided under
                        this Agreement.

           representation,  express or  implied,  on the part of Owner  Trustee,
           Lender or Sublessor and all claims against Owner  Trustee,  Lender or

18.11      No Waiver

           Nothing in this  Clause 18 or  elsewhere  in this  Agreement  will be

18.12      Confirmation

           Sublessee  confirms that the  foregoing  provisions of this Clause 18

           payable under this Agreement.

19.        INDEMNITIES

19.1       General Indemnity

           Sublessee  agrees to defend,  indemnify and hold harmless on an after
           Tax basis each of the  Indemnitees on demand from and against any and
           all Losses arising from events occurring during the Sublease Term:

           (i)          that may at any time be suffered or incurred directly or
                        indirectly as a result  of  or  in  connection with  the
                        possession,     delivery,    performance,    management,
                        ownership, registration, import,  control,  maintenance,
                        condition,    service,    repair,   Overhaul,   leasing,
                        subleasing,   deregistration,    export,    manufacture,
                        storage, transportation, design,  testing,  replacement,
                        use, operation or redelivery of the Aircraft, any Engine
                        or Part (either in the air or on the  ground) whether or
                        not such Losses may be attributable to any defect in the
                        Aircraft, any Engine or any Part or to their  respective
                        design, testing or  use  or  otherwise,  and  regardless
                        of when the same arises (but excluding any  injuries  or
                        claims which arise prior  to  Delivery)  or  whether  it
                        arises out of or is attributable to any act or omission,
                        negligent  (active  or  passive)  or  otherwise,  of any
                        Indemnitee  (including  without  limitation  claims  for
                        death,  personal  injury, property damage, other loss or
                        harm to any person and  claims  relating  to  any  Laws,
                        including   without  limitation  environmental  control,
                        noise and pollution laws rules or regulations);



<PAGE>


           (ii)         that  may at any  time  be  suffered  or  incurred  as a
                        consequence of any breach of the  Transaction  Documents
                        by the Sublessee or by misrepresentation of or breach of
                        warranty by Sublessee; and

           (iii)        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
                        by Sublessee,  or anyone acting by or through Sublessee,
                        of any obligation of confidentiality  owed to any person
                        in respect  of any of the  matters  referred  to in this
                        Clause 19.1 (iii).

19.2       Exception to General Indemnity

           The indemnity provided for in Clause 19.1 will not extend to any Loss
           in relation to a particular Indemnitee to the extent that such Loss:

           (i)          arises  as  a  direct  result of the gross negligence or
                        wilful misconduct of such Indemnitee; or

           (ii)         arises  as  a  direct  result  of  Sublessor   Taxes,  a
                        Sublessor  Lien or a willful  breach by Sublessor of its
                        obligations under any of the Transaction Documents; or

           (iii)        constitutes a Tax or liability for Taxes.

19.3       Time of Payment

           Sublessee  will pay an Indemnitee for Losses within ten (10) Business
           Days after receipt of a written demand  therefor from such Indemnitee
           accompanied by a written  statement  describing in reasonable  detail
           the basis for such indemnity.

19.4       Survival of General Indemnity

           Notwithstanding  anything  in this  Agreement  to the  contrary,  the
           provisions  of Clause 19.1 shall  survive the Expiry Date for two (2)
           years and  continue  in full  force and  effect  notwithstanding  any
           breach by Sublessor or Sublessee of the terms of this Agreement,  the
           termination  of the Sublease of the Aircraft to Sublessee  under this
           Agreement  or the  repudiation  by  Sublessor  or  Sublessee  of this
           Agreement.



<PAGE>


19.5       Notice to Sublessee

           Sublessor shall promptly after  obtaining  actual  knowledge  thereof
           notify  the  Sublessee  of any claim as to which  indemnification  is
           sought;  provided  that a failure to so notify  will not  diminish or
           relieve Sublessee of any obligations  hereunder,  unless such failure
           materially  adversely affects  Sublessee's  defence of such claim and
           directly results in a material increase in liability of the Sublessee
           in respect  of such claim or  prevents  it from  materially  reducing
           liability therefor, in which case the Sublessee shall not be required
           to indemnify  such  Indemnitee for the amount by which such liability
           was increased or not reduced.

20.        TAXATION

20.1       Gross-up

20.1.1     All payments by Sublessee  under or in connection with this Agreement
           shall be made in full without any set-off or  counterclaim,  free and
           clear of and without  deduction or  withholding  for or on account of
           all Taxes,  except Sublessor  Taxes,  unless Sublessee is required by
           law to make any such deduction or withholding.

20.1.2     If any Taxes,  except Sublessor Taxes, are required to be deducted or
           withheld from any amount payable  hereunder,  Sublessee  shall pay to
           Sublessor by way of Supplemental Rent such additional amounts, in the
           same  currency as such  payment as may be necessary in order that the
           amount of the net payment  received by  Sublessor on the date of such
           payment,  after deduction or withholding for all such Taxes,  will be
           equal to the amount that Sublessor  would have received if such Taxes
           had not been deducted or withheld.

20.1.3     If any payment is made by Sublessee  under Clause 19.2 and  Sublessor
           in good  faith  determines  that it is  entitled  to receive a credit
           against, or relief or remission for, or repayment of, any Tax paid or
           payable by Sublessor in respect of or  calculated  with  reference to
           the deduction or withholding  giving rise to such payment,  Sublessor
           shall,  to the  extent  that it can do so  without  prejudice  to the
           retention  of  the  amount  of  such  credit,  relief,  remission  or
           repayment  and without  leaving  Sublessor in any worse net after tax
           position than that in which it would have been had such  deduction or
           withholding  not been required to be made,  promptly pay to Sublessee
           such amount as  Sublessor  shall  reasonably  have  determined  to be
           attributable to the relevant deduction or withholding.

20.2       Tax Indemnity

20.2.1     Sublessee  shall  indemnify  Sublessor  on demand  against  all Taxes
           (other  than  Sublessor  Taxes)  levied or  imposed  against  or upon
           Headlessor,   Sublessor,   Sublessee  or  the  Aircraft  directly  or
           indirectly  in   connection   with  the   importation,   exportation,
           registration,  ownership,  leasing,  subleasing,  purchase, delivery,
           sale,  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  except to the
           extent that such liability for such Taxes:

           (i)          arises as a result of a Sublessor Lien; or

           (ii)         arises in respect of the period ending prior to Delivery
                        and commencing immediately after the Expiry Date; or

           (iii)        is directly attributable to Sublessor's gross negligence
                        or willful misconduct; or

           (iv)         relates to any deduction or  withholding  on any payment
                        to be made to Sublessor  that is covered by Clause 20.1;
                        or

           (v)          imposed  as a direct  result  of the sale,  transfer  or
                        assignment or other  disposition of the Aircraft or this
                        Agreement  by  Sublessor,  other  than by  Sublessor  to
                        Sublessee,  or by  any  party  claiming  by  or  through
                        Sublessor and except (a) any sale, transfer,  assignment
                        or other  disposition that is made solely as a result of
                        the  occurrence  of an Event of Default or Total Loss of
                        the Aircraft or any part thereof or interest therein and
                        (b) any Taxes imposed by the State of Registration.



<PAGE>


20.2.2     If  Sublessor  becomes  aware  of any claim against Sublessor for any
           Loss that Sublessee is required to pay or indemnify against  pursuant
           to  this  Clause 20.2,  Sublessor  shall  as  soon as  is  reasonably
           practicable  notify  Sublessee in writing of such claim. If requested
           in writing by Sublessee that it  wishes  Sublessor  to  contest  such
           claim,  Sublessor   will  consult  with  Sublessee  with  a  view  to
           determining whether there  are  grounds  for  contesting  such claim.
           Sublessor will consider in good  faith  any  representation  made  by
           Sublessee  in  this  respect.  Sublessor  shall  not  be  under   any
           obligation  to  bring any proceedings in respect of any such claim in
           any court of law or other  relevant forum except that Sublessor shall
           bring such proceedings in  the  event  that  tax  counsel  reasonably
           acceptable  to  Sublessor  in  the  relevant   jurisdiction  provides
           Sublessor  with  a  legal  opinion  to  the  effect  that  there  are
           legitimate grounds for contesting such claim. Any costs and  expenses
           of any such contest shall be fully indemnified by Sublessee.  Further
           Sublessor shall be under no obligation to take any action in  respect
           of any claim unless it  shall  previously  have  been  provided  with
           security  in  an  amount  equal  to  the  amount  of  such  claim and
           reasonable  costs   and   otherwise   satisfactory  in  its  absolute
           discretion for any such costs. Any amount payable under  this  Clause
           20.2 shall be paid to or on behalf of Sublessor or, if so directed by
           Sublessor, directly to the relevant taxing authority,  promptly after
           receipt by Sublessee of a written demand therefor.

20.3       Value Added Taxes

           The Rent and other amounts  payable by Sublessee under this Agreement
           are exclusive of any value added tax,  turnover tax or similar tax or
           duty.  If a value  added tax or any similar tax or duty is payable in
           any  jurisdiction  in  respect  of  any  Rent  or  other  amounts  as
           aforesaid,  Sublessee  will pay all  such  tax or duty and  indemnify
           Sublessor  against  any claims for the same and any  related  claims,
           losses or liabilities.

20.4       Taxation of Indemnity Payments

20.4.1     Notwithstanding any other provision of this Agreement,  if and to the
           extent that any sums payable to any  Indemnitee  by  Sublessee  under
           this Agreement by way of indemnity are insufficient, by reason of any
           Taxes  payable in  respect  of those  sums,  for such  Indemnitee  to
           discharge  the  corresponding  liability to the relevant  third party
           (including any taxation  authority),  or to reimburse such Indemnitee
           for the cost incurred by it to a third party  (including any taxation
           authority)  Sublessee  shall pay to such  Indemnitee such sum as will
           after  the  tax  liability  has  been  fully   satisfied  leave  that
           Indemnitee  with the same  amount as it would have been  entitled  to
           receive in the absence of that liability.

20.4.2     If and  to  the  extent  that  any  sums  constituting  (directly  or
           indirectly)  an indemnity to an  Indemnitee  but paid by Sublessee to
           any person other than such  Indemnitee  are treated as taxable in the
           hands of such Indemnitee, Sublessee shall pay to such Indemnitee such
           sum as  will,  after  the tax  liability  has been  fully  satisfied,
           indemnify  such  Indemnitee  to the same extent as it would have been
           indemnified in the absence of such liability.

20.5       Benefit of Indemnities

           All rights  expressed  to be granted to each  Indemnitee  (other than
           Sublessor)  under this  Agreement are given to Sublessor on behalf of
           that Indemnitee.



<PAGE>


20.6       Sublessor Indemnification

           Without  prejudice to Clause 20.5,  Sublessor  shall be entitled (but
           not obliged) to indemnify Indemnitees (other than Sublessor) on terms
           equivalent to the indemnities given by Sublessee under this Agreement
           and the  obligations  of  Sublessee  to  Sublessor  shall  extend  to
           reimbursement  of Sublessor of any amount  properly paid by Sublessor
           to such other Indemnitee  provided always that nothing in this Clause
           20.6 shall  operate to increase the  obligations  or  liabilities  of
           Sublessee.

20.7       Survival of Tax Indemnities

           Notwithstanding  anything  in this  Agreement  to the  contrary,  the
           provisions of Clause 19 shall survive the Expiry Date and continue in
           full force and effect  notwithstanding  any  breach by  Sublessor  or
           Sublessee  of the terms of this  Agreement,  the  termination  of the
           Sublease of the  Aircraft to  Sublessee  under this  Agreement or the
           repudiation by Sublessor or Sublessee of this Agreement.

20.8       Mitigation and Co-operation

           In any case  where  Sublessee  would be obliged to bear Taxes or make
           additional  payment on account of Taxes pursuant to the provisions of
           this  Agreement  as a result  of any  change  in  applicable  laws or
           regulations or practice,  Sublessor  shall at the written  request of
           Sublessee,  without  limiting,  reducing or otherwise  qualifying the
           rights of Sublessor and the Security Interest of Lender, consult with
           Sublessee  in  good  faith  as to  such  steps  which  Sublessor  and
           Sublessee can mutually  accept and agree upon in order to mitigate or
           avoid  the  effects  of such  circumstances.  In case  Sublessor  and
           Sublessee  can not agree  within a period of thirty  (30) days  after
           Sublessee has made a written  request,  Sublessor  shall not have any
           further obligation towards Sublessee.

20.9       Furnishing Forms

           Sublessor agrees to furnish, and to procure that any other Indemnitee
           furnishes to  Sublessee,  or to such other  person as  Sublessee  may
           designate,  at Sublessee's sole cost and expense,  such duly executed
           and properly  completed forms as such Indemnitee may be permitted and
           legally  able to deliver and as may be necessary  or  appropriate  in
           order to claim  any  reduction  of, or  exemption  from any Tax which
           Sublessee may be required to indemnify against hereunder, unless such
           Indemnitee  reasonable determines that furnishing such forms may have
           an adverse effect on either the business,  tax status,  tax liability
           or operations of such Indemnitee.

21.        INSURANCE

21.1       Insurances

21.1.1     Sublessee  shall,  at its own  expense,  maintain  in full  force and
           effect during the Sublease Term insurances in respect of the Aircraft
           that, subject to this Clause 21, comply with the requirements set out
           in Schedule 3 (the Insurances).

21.1.2     The Insurances  shall be effected  through  brokers of  international
           standing  and  repute in the  London or New York  aviation  insurance
           markets as may be  approved by  Sublessor,  such  approval  not to be
           unreasonably withheld.

21.1.3     For the avoidance of doubt it is understood that the Insurances to be
           provided  for by  Sublessee  are  not  Sublessor's  sole  remedy  and
           protection  under this Agreement as the  obligations of Sublessee are
           in excess of the requirements of the Insurances.

21.2       Reinsurance

           Any  reinsurance  will be  maintained  with  reinsurers  and  brokers
           approved by Sublessor, such approval not to be unreasonably withheld.
           Such reinsurance will contain each of the following terms and will in
           all other respects (including amount) be satisfactory to Sublessor:

           (i)          The same terms as the original insurance;

           (ii)         A cut-through and assignment clause satisfactory to Subl

           (iii)        Payment will be made notwithstanding (a) any bankruptcy,
                        insolvency,  liquidation  or  dissolution  of any of the
                        original  insurers and/or (b) that the original insurers
                        have  made  no  payment  under  the  original  insurance
                        policies.

21.3       Requirements

           this Clause 21 and in Schedule 3.  Sublessor and Lender may from time
           to time stipulate other  requirements  for the Insurances so that (a)
           the  scope  and  level of cover  are  maintained  in line  with  best
           international  airline practice,  and (b) the interests of Sublessor,
           Headlessor  and Lender  continue  to be  protected.  Sublessee  shall
           procure that such changes are effected.

21.6       Failure to Insure

           If Sublessee fails to maintain the Insurances in compliance with this
Agreement, Sublessee shall:

           (i)          forthwith  ground or cause to be grounded  the  Aircraft
                        and shall  keep or  procure  that the  Aircraft  be kept
                        grounded  until  such time as all the  Insurances  shall
                        again be in full force and effect; and

           (ii)         immediately  notify Sublessor of the  non-compliance  of
                        the Insurances  and provide  Sublessor with full details
                        of any steps  which  Sublessee  is taking or proposes to
                        take, in order to remedy such non-compliance;

           and each of the Indemnitees  will be entitled but not bound,  without
           prejudice to any other rights of Sublessor under this Agreement:

                        (a)        to pay  the  premiums  due or to  effect  and
                                   maintain insurances satisfactory to Sublessor
                                   and  substantially the same as the Insurances
                                   required   hereunder  or   otherwise   remedy
                                   Sublessee's failure in such manner, including
                                   to effect and maintain an "owner's  interest"
                                   policy, as Sublessor  considers  appropriate.
                                   Any sums so expended by Sublessor will become
                                   immediately  due and payable by  Sublessee to
                                   Sublessor  together with interest  thereon at
                                   the   Default   Rate,   from   the   date  of
                                   expenditure  by  Sublessor  up to the date of
                                   reimbursement by Sublessee; 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  Sublessor  until the
                                   failure   is    remedied    to    Sublessor's
                                   satisfaction.

21.7       Continuation of Insurances

           Sublessee  agrees to effect and maintain at Sublessee's  cost airline
           general third party liability insurances in the form required by this
           Agreement  for two (2) years  after the  Expiry  Date  whether or not
           Sublessee  or  Sublessor  continues  to  have  any  interest  in  the
           Aircraft,  and to continue to name the parties listed in Schedule 3 -
           Insurance Requirements,  to this Agreement as Additional Insureds for
           that period.

21.8       Application of Insurance Proceeds

           As between Sublessor and Sublessee:

           (i)          all insurance payments received as the result of a Total
                        Loss occurring  during the Sublease Term will be paid to
                        Sublessor  or to  Lender  pursuant  to the  terms of any
                        security given by Owner Trustee and Sublessor;

           (ii)         all  insurance  proceeds  of any  damage  or loss to the
                        Aircraft,  any Engine or any Part  occurring  during the
                        Sublease  Term  not  constituting  a Total  Loss  and in
                        excess of the Damage Notification Threshold will be paid
                        to  Sublessor  and applied in payment  (or to  reimburse
                        Sublessee)  for repairs or  replacement  property,  upon
                        Sublessor   being   satisfied   that  the   repairs   or
                        replacement  have been effected in accordance  with this
                        Agreement; and

           (iii)        notwithstanding  Clauses 21.8 (i) or 21.8 (ii) above, 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 Sublessor
                        to be applied toward payment of any amounts which may be
                        or  become   payable  by  Sublessee  in  such  order  as
                        Sublessor sees fit or as Sublessor may elect.

21.9       Pursuit of Claims

           The parties  shall  co-operate in the pursuit of any claims under the
           Insurances.  In pursuing  any such  claims,  the  parties  shall take
           account  of each  others  interests  but,  if there  is any  material
           disagreement  between  the  parties  in respect of how any such claim
           shall be pursued, the interests of Sublessor shall be paramount.

22.        TOTAL LOSS AND REQUISITION

22.1       Total Loss Prior to Delivery

           If a Total  Loss  occurs  prior to  Delivery,  this  Agreement  shall
           immediately  terminate,  and  except  as  expressly  stated  in  this
           Agreement neither party will have any further obligation or liability
           under this  Agreement,  except that Sublessor will repay to Sublessee
           any prepaid Rent, the amount of Security Deposit, if paid, and return
           the Letter of Credit under this Agreement.



<PAGE>


22.2       Total Loss After Delivery

           Sublessor on or prior to the earlier of:

           (i)          thirty (30) days after the Total Loss Date; and

           (ii)         the date of receipt  of  insurance  proceeds  in respect
                        of such Total Loss,

           the  aggregate  of (x) the  Agreed  Value  and (y) Rent and all other
           amounts  accrued under this  Agreement to the date of payment and (z)
           interest on the Agreed Value accruing on a daily basis at the Default
           Rate for the period,  if any, from the Total Loss Date to the date of
           payment.

22.2.2     Subject to the rights of any insurers or other  third  parties,  upon
           irrevocable payment in full to Sublessor of the Agreed  Value and all
           other amounts which may be or become payable  to Sublessor under this
           Agreement,  Sublessor  shall  direct  Owner  Trustee  to  transfer to
           Sublessee all of Owner Trustee's and Sublessor's  rights (if any)  to
           (x) the Airframe or any Engines and Parts whether  or  not  installed
           when the Total Loss occurred, on an as-is where-is basis  and without
           recourse or warranty (save as to freedom  from Sublessor Liens),  and
           Sublessor shall procure the execution and delivery  of such  bills of
           sale and other instruments as  Sublessee  may  reasonably  request to
           evidence such transfer, free and clear of all rights of Owner Trustee
           and Sublessor and (y) any  other rights in respect of the Aircraft or
           any part thereof or any further requisition  or insurance proceeds in
           respect  thereof.   Sublessee   shall  indemnify  Owner  Trustee  and
           Sublessor for all fees, expenses and Taxes incurred by Owner  Trustee
           and Sublessor in connection with any such transfer.

22.2.3     If a Total Loss of the  Aircraft or the  Airframe  occurs  during the
           Sublease Term,  Sublessee's  obligation to pay Rent shall continue in
           full force and effect  until the date of payment of the Agreed  Value
           and all other  amounts due under this  Agreement  and upon payment of
           the Agreed  Value and all other sums due under  this  Agreement,  the
           leasing of the  Aircraft  shall  immediately  terminate,  but without
           prejudice to the continuing obligations of Sublessee (as to indemnity
           or otherwise)  under this Agreement and Sublessor and, if not already
           recovered,  Sublessee shall proceed  diligently and co-operate  fully
           with each other in the recovery of the Total Loss Proceeds.

22.3       Total Loss of Engines



<PAGE>


22.3.1     Upon  an  Engine  Total  Loss  of any  Engine  not  installed  on the
           Aircraft,  or an  Engine  Total  Loss of an Engine  installed  on the
           Airframe not  involving a Total Loss of the Airframe (in either case,
           a Destroyed  Engine),  Sublessee shall give Sublessor  prompt written
           notice  thereof and Sublessee  shall replace the Destroyed  Engine as
           soon as reasonably possible by procuring that Owner Trustee acquires,
           at Sublessee's  expense,  title to another engine  complying with the
           requirements  of Clause  16.6.  Such  Replacement  Engine  shall upon
           acquisition by Owner Trustee be an Engine as defined herein.

22.3.2     Sublessee  agrees to take such  action as  Sublessor  may  reasonably
           request  in  order  that  any such  Replacement  Engine  shall be the
           property of Owner Trustee,  and leased hereunder on the same terms as
           the  Destroyed  Engine.  Sublessee's  obligation  to pay  Rent  shall
           continue in full force and effect,  but an amount  equal to the Total
           Loss  Proceeds  received by Sublessor or Lender,  as the case may be,
           with respect to the Destroyed Engine, less any cost, expenses,  Taxes
           or duties incurred in connection with the collection thereof,  shall,
           subject to Sublessor's right to deduct therefrom any amounts then due
           and payable by Sublessee under this Agreement, be paid to Sublessee.

22.3.3     Immediately upon the effectiveness of such substitution,  and without
           further act,  title to the replaced  Engine shall  thereupon  vest in
           Sublessee,  in an as-is,  where-is  condition,  free and clear of all
           rights and Security Interests of Owner Trustee,  Lender and Sublessor
           and shall no longer be deemed an Engine hereunder.

22.4       Requisition

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

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

           (ii)         so long as no Default or Event of Default  has  occurred
                        and is  continuing,  Sublessee  shall be entitled to any
                        hire paid by the requisitioning  authority in respect of
                        the Sublease Term;

           (iii)        Sublessee shall, as soon as practicable after the end of
                        any such requisition,  cause the Aircraft to be put into
                        the condition required by this Agreement.



<PAGE>


22.4.2     If the Aircraft is under requisition for hire at the Expiry Date, the
           leasing of the Aircraft under this Agreement shall continue until the
           earlier of (x) when the Aircraft  becomes a Total Loss and  Sublessor
           receives the Agreed Value  together  with any other  amounts then due
           and unpaid under this Agreement and (y) when the Aircraft is returned
           prior to becoming a Total Loss,  and  Sublessee  satisfies the Return
           Conditions provided that:

           (i)          the  obligations  of  Sublessee  including in respect of
                        payment of Rent including  Maintenance Reserves, if any,
                        shall  continue  in full  force  and  effect  until  the
                        leasing ends except that during the  continuation of the
                        requisition  for hire  while it does  not  constitute  a
                        Total Loss,  Sublessee  shall be released  from those of
                        its obligations  that it is prevented from performing as
                        a result of the requisition of the Aircraft;

           (ii)         unless a Total Loss has  occurred  (in which case Clause
                        22.2  shall  apply),   Sublessee  shall  be  obliged  to
                        redeliver the Aircraft to Sublessor in  accordance  with
                        Clause 23;

           (iii)        provided  no Default or Event of Default is  continuing,
                        Sublessee  shall be  entitled  to receive and retain any
                        requisition  payments  made in respect of the  Aircraft;
                        and

           (iv)         Sublessee shall indemnify Sublessor for any Losses which
                        Sublessor  suffers  (Sublessor  undertakes  to  use  its
                        reasonable  best  efforts to mitigate  such Losses) as a
                        result of Sublessee  returning the Aircraft to Sublessor
                        after the Expiry Date.

23.        REDELIVERY

23.1       Redelivery of Aircraft

           On the  Redelivery  Date,  Sublessee  shall,  unless a Total Loss has
           occurred,  redeliver  the  Aircraft  and the  Aircraft  Documents  to
           Sublessor at Sublessee's cost and expense at the Redelivery Location.
           If the Aircraft  has been  damaged and is being  repaired in a timely
           manner,   then  the  term  of  the  Sublease  will  be  extended  and
           Sublessee's  obligations  under this Agreement shall continue in full
           force and effect and during the course of such repair and, so long as
           no Default or Event of Default shall have occurred and be continuing,
           the Sublessor  will make insurance  proceeds  available to accomplish
           such  repairs  as  provided  in  Clause  22.  When  the  repairs  are
           completed,  the Aircraft shall be  redelivered  to Sublessor.  At the
           time of the redelivery of the Aircraft:



<PAGE>


           (i)          the  Aircraft shall  be  free  and clear of all Security
                        Interests other than Sublessor Liens;

           (ii)         all  maintenance to the Aircraft due for  performance on
                        or before the Redelivery  Date shall have been completed
                        in accordance with this Agreement;

           (iii)        the  Aircraft  shall  be  in  compliance with the Return
                        Conditions;

           (iv)         the  Aircraft  shall  comply with such other  reasonable
                        requirements as Sublessor may request that Sublessee has
                        had timely  notice of and that  Sublessor  has agreed to
                        pay for;  provided,  however,  that if  compliance  with
                        Sublessor's  request is the sole cause of a delay in the
                        return of the Aircraft beyond the Expiry Date, then Rent
                        shall  abate  for  the  period  of  such  delay   solely
                        attributable to Sublessee's  compliance with Sublessor's
                        request; and

           (v)          any service  bulletin  kits which are  allocated  to the
                        Aircraft  at no  charge  by  the  Manufacturer  and  not
                        delivered to Sublessor as at the Redelivery Date will be
                        shipped  to  a  location   specified   by  Sublessor  at
                        Sublessee's cost.

23.2       Final Inspection

           Immediately prior to redelivery of the Aircraft, Sublessee shall make
           the Aircraft available to Sublessor for inspection (Final Inspection)
           at the  Redelivery  Location in order to verify that the condition of
           the  Aircraft  complies  with  the  Return   Conditions.   The  Final
           Inspection shall be long enough to permit Sublessor to:

           (i)          inspect the Aircraft Documents;

           (ii)         inspect the Aircraft and uninstalled Parts;

           (iii)        inspect the Engines,  including without limitation (i) a
                        video  boroscope  inspection of (A) the low pressure and
                        high pressure  compressors and (B) turbine area and (ii)
                        engine condition runs.

23.3       Discrepancies

           Sublessee shall repair all discrepancies  discovered during the Final
           Inspection and demonstration  flight, which exceed maintenance manual
           allowable limits, and shall correct all discrepancies in the Aircraft
           Documents.   When  Sublessee has complied with the provisions of this
           Clause 23.3, Sublessee shall redeliver the Aircraft  to  Sublessor at
           Sublessee's cost and expense at the Redelivery Location.

23.4       Non-compliance

23.4.1     To the extent that, at the time of Final Inspection, the condition of
           the Aircraft does not comply with this Agreement  (except Clause 23.1
           (iv)), Sublessee shall at Sublessor's option:

           (i)          immediately rectify the non-compliance and to the extent
                        the  non-compliance  extends beyond the Redelivery Date,
                        the Sublease Term will be  automatically  extended until
                        the  non-compliance  has been  rectified  and  Sublessee
                        shall be required to pay Rent to  Sublessor  during that
                        period  at the rate  equal to two (2)  times  the  daily
                        Basic Rent (Basic Rent per month divided by thirty (30))
                        per day payable  monthly or, if earlier,  on the date on
                        which the  non-compliance is rectified and the return of
                        the Aircraft is accepted by Sublessor; or

           (ii)         redeliver   the  Aircraft  to  Sublessor  and  indemnify
                        Sublessor,  and provide  cash to  Sublessor in an amount
                        reasonably  satisfactory  to  Sublessor  as security for
                        that indemnity, against the cost of putting the Aircraft
                        into the condition required by this Agreement.

23.4.2     Sublessor's  option  in Clause  23.4 is not  available  to  Sublessor
           provided that (i)  Sublessee has notified  Sublessor of its intent to
           rectify  the  non-compliance  prior to the  Redelivery  Date and (ii)
           Sublessee  will in the  reasonable  opinion of  Sublessor  be able to
           rectify such non-compliance on or before Redelivery Date.

23.4.3     For the  avoidance  of  doubt,  Sublessor  shall not be  entitled  to
           exercise its option under Clause 23.4.1 and Sublessee shall suffer no
           loss or penalty to the extent  that the  Aircraft  does not, on Final
           Inspection,  comply  with  Clause  23.1  (iv)  but  is  otherwise  in
           compliance with the Return Conditions.

23.5       Acknowledgment

           Provided  Sublessee  has  complied  with its  obligations  under this
           Agreement,  following  redelivery  of the  Aircraft by  Sublessee  to
           Sublessor at the  Redelivery  Location,  the parties shall execute an
           acknowledgment confirming that Sublessee has redelivered the Aircraft
           to Sublessor in accordance with this Agreement  substantially  in the
           form of Schedule 13.

23.6       Storage

           Notwithstanding  the  performance  in  full by  Sublessee  of all its
           obligations  under this Clause 23, Sublessor may require Sublessee to
           continue to lease the Aircraft  from  Sublessor for a period of up to
           thirty (30) days from the Expiry Date. During this period,  Sublessee
           will have no  obligations  under  this  Agreement  except to park and
           store the  Aircraft in  accordance  with  Manufacturer's  recommended
           short term storage program at one of Sublessee's  storage  facilities
           and to continue  Insurances in respect of the Aircraft at Sublessee's
           cost. Such parking and storage is being made at the risk of Sublessor
           and Sublessee shall have no liability for Losses beyond those covered
           by the  Insurances  except for any Losses  arising out of Sublessee's
           gross  negligence or willful  misconduct  arising during such period.
           Sublessee also agrees during this period to ferry/fly the Aircraft to
           such location as Sublessor may require.  Sublessee will not otherwise
           utilise the Aircraft  during this period.  Any out of pocket costs or
           expenses incurred by Sublessee during this period with respect to the
           Aircraft  for  storage,  insurance  or  such  ferry/flight  shall  be
           reimbursed by Sublessor to Sublessee  promptly  after demand and upon
           receipt by  Sublessor  of an invoice  and  documentation,  reasonably
           satisfactory to Sublessor, of such costs and expenses.

24.        EVENTS OF DEFAULT

24.1       Notice

           Sublessee will promptly notify  Sublessor if Sublessee  becomes aware
of the occurrence of any Default.

24.2       Events

                        respect of payments of Rent or Maintenance  Reserves, if
                        any,  within three (3) Business Days of the due date for
                        payment  thereof and, in respect of any other  payments,
                        within five (5) Business  Days of the date of receipt of
                        written notice for payment thereof;



<PAGE>


           (ii)         Insurance:  Insurance  cover on or with  respect  to the
                        Aircraft   for  the  benefit  of   Sublessor   (and  any
                        additional insured) is not maintained in accordance with
                        the  provisions  of this  Agreement  or the  Aircraft is
                        operated  outside the scope of such insurance  coverage;
                        or

           (iv)         Redelivery:  Sublessee  fails to return the  Aircraft to
                        Sublessor  on the  Redelivery  Date in  accordance  with

                        observance  of any other  obligations  contained  in the
                        Transaction  Documents  and such default is not remedied
                        within  fourteen  (14)  days of  becoming  aware of such
                        default; or

                        statement  made or deemed to be made by Sublessee in the

                        or opinion  delivered by it  hereunder or in  connection
                        herewith is  incorrect,  inaccurate or misleading in any
                        material  respect  when  made or deemed to be made or if
                        the effects or consequences of the incorrect, inaccurate
                        or misleading representation,  warranty or statement are
                        capable of cure and Sublessee fails to cure such effects
                        or  consequences  within twenty (20) days after becoming
                        aware of such default; or

                        authorization  required  by  law  for  the  validity  or
                        legality of the Transaction Documents or the performance
                        hereof  or  thereof  (other  than any such  which may be
                        required to be obtained by  Sublessor)  is  withdrawn or
                        ceases,  for any reason,  to be in full force and effect
                        or is not renewed or  obtained  when  required  and such
                        withdrawal,  cessation,  non-renewal or non-obtaining in
                        the opinion of  Sublessor  may  prejudice  the rights of
                        Sublessor  under  this  Agreement  or in the  reasonable
                        opinion of Sublessor may have a material  adverse effect
                        on  Sublessee's  obligation  to perform its  obligations
                        under this Agreement; or

                        opinion of Sublessor may have a material negative impact
                        on  Sublessee's   ability  to  perform  its  obligations
                        hereunder; or

                        Sublessee,  the  same  will  be an  immediate  Event  of
                        Default.  If instituted by another person, the same will
                        be an Event of Default  if not  dismissed,  remedied  or
                        relinquished within twenty (20) days; or

                        substantial  part of its  property  or if a  substantial
                        part of its property is to be sequestered. If instituted
                        by Sublessee or done by the Sublessee,  the same will be
                        an immediate Event of Default.  If instituted by another
                        person,  the same  will be an Event  of  Default  if not
                        dismissed,  remedied or relinquished  within twenty (20)
                        days; or

                        unpaid Air Navigation Charges due from Sublessee (unless
                        such  charges are being  contested  in good faith and by
                        appropriate  proceedings  and  such  proceedings  do not
                        involve any danger of the detention,  interference  with
                        the use or  operation,  sale,  forfeiture or loss of the
                        Aircraft)  and  such  charges  remain  outstanding  of a
                        period  of ten (10)  days  from  the due  date  thereof;
                        provided  that such ten (10) day grace  period  will not
                        apply if there is a danger  of  detention,  interference
                        with the use or operation,  sale,  forfeiture or loss of
                        the Aircraft; or

           (xvii)       Airport Charges:  Any airport has unpaid Airport Charges
                        due  from  Sublessee  (unless  such  charges  are  being
                        contested in good faith and by  appropriate  proceedings
                        and such  proceedings  do not  involve any danger of the
                        detention, interference with the use or operation, sale,
                        forfeiture  or loss of the  Aircraft)  and such  charges
                        remain  outstanding  for a period  of ten (10) days from
                        the due date  thereof;  provided  that such ten (10) day
                        grace  period  will not  apply  if there is a danger  of
                        detention, interference with the use or operation, sale,
                        forfeiture or loss of the Aircraft;

           (xviii)      Other  Default:   An  Event  of  Default  is  continuing
                        unremedied under any Other Agreement  between  Sublessee
                        and Sublessor or another Sublessor or sub-sublessor that
                        either   (i)  shares   the  same   general   partner  or
                        controlling  shareholder  with  Sublessor  or (ii) whose
                        beneficiary   shares   the  same   general   partner  or

           (xix)        Sub-sublessee:  Any approved sub-sublessee acts so as to
                        prevent  present or future  performance  by Sublessee of
                        its obligations under this Agreement.

24.3       Sublessor's Rights



<PAGE>


24.3.1     Upon the occurrence of any Event of Default,  all rights of Sublessee
           under  this   Agreement   and  with  respect  to  the  Aircraft  will
           immediately  cease  and  terminate,  but  without  prejudice  to  the
           continuing  obligations of Sublessee  under this  Agreement.  Without
           prejudice  and in all  cases  in  addition  to any  other  rights  of
           Sublessor under this Agreement or under applicable law, Sublessor may
           upon the  occurrence  of any Event of Default  exercise all or any of
           the following rights at its option:

           (i)          require  that Sublessee immediately move the Aircraft to
                        a location specified by Sublessor;

           (ii)         for Sublessee's  account do anything that may reasonably
                        be  required  to  cure  any  default  and  recover  from
                        Sublessee all  reasonable  costs,  including  reasonable
                        legal  fees  and  expenses  incurred  in  doing  so  and
                        interest thereon at the Default Rate; or

           (iii)        proceed  by  appropriate  court  action  or  actions  to
                        enforce  performance  of this  Agreement  or to  recover
                        damages for the breach of this Agreement; or

           (iv)         enter upon the premises where the Airframe or any or all
                        Engines or any or all Parts are  located or  believed to
                        be located and take  immediate  possession of and remove
                        such Airframe, Engine or Parts without the necessity for
                        first instituting proceedings, or by summary proceedings
                        or otherwise,  and Sublessee shall comply therewith, all
                        without  liability to Sublessor for or by reason of such
                        entry or taking possession,  whether for the restoration
                        or  damage  to   property   caused  by  such  taking  or
                        otherwise;

           (v)          apply all or any portion of the  Security  Deposit,  the
                        Letter of Credit and any other security  deposit held by
                        Sublessor  pursuant  to  any  Other  Agreements  to  any
                        amounts due.

24.3.2     Whether or not Sublessor shall have exercised,  or  shall  thereafter
           any time exercise, any of its rights under Clause 24.3.1  (i) or (iv)
           above with respect to all or any part of the Aircraft, Sublessor may,
           by written notice to Sublessee specifying a payment date not  earlier
           than  ten  (10)  days  from  the  date  of  such  notice, demand that
           Sublessee pay to Sublessor, and Sublessee shall pay Sublessor, on the
           payment date specified in such notice as liquidated damages  and  not
           as a penalty (in lieu of the  installments  of  Rent  due for periods
           commencing on or  after  the payment date in such notice), any unpaid
           installments  of  Rent  due  for  periods  prior  to the payment date
           specified in such notice plus the  present  value  of  the  remaining
           installments of Rent during  the  Sublease Term, using in each case a
           discount rate of  the  amount  of interest then paid on U.S. Treasury
           Bills of similar maturity. In addition, Sublessee shall be liable for
           the amounts set forth in 24.4 (ii ) and (iii).



<PAGE>


24.3.3     If an Event of Default  occurs,  Sublessor  may sell or  re-lease  or
           otherwise  deal with the  Aircraft at such time and in such manner as
           Sublessor considers appropriate in a commercially  reasonable manner,
           free and clear of any interest of Sublessee as if this  Agreement had
           never  been  entered  into and as if  Sublessee  had  never  made any
           payments  hereunder.   While  an  Event  of  Default  is  continuing,
           Sublessee  will not  operate  the  Aircraft  without  the  consent of
           Sublessor.

24.3.4     If an Event of Default has occurred and is continuing,  Sublessor may
           take all steps  necessary to  de-register  the Aircraft in and export
           the Aircraft from the State of Registration.

24.4       Default Payments

           Sublessee shall be liable for:

           (i)          any  and  all  unpaid Rent due hereunder before or after
                        any termination hereof;

           (ii)         any  and  all  unpaid  Supplemental  Rent  due hereunder
                        before or after any termination hereof;

           (iii)        all costs and expenses  (including  attorney's  fees and
                        disbursements)  incurred by Sublessor in connection with
                        or as a result of any Event of  Default or  exercise  of
                        remedies hereunder,  including,  but not limited to, (i)
                        all costs  and  expenses  incurred  in  connection  with
                        recovering  possession  of the  Aircraft and in carrying
                        out any  works or  modifications  required  to place the
                        Aircraft in the  condition  specified in Clause 23.1 and
                        remarketing  the Aircraft,  (ii) interest at the Default
                        Rate  on  any  amount  not  paid  when  due  under  this
                        Agreement  and  (iii)  an  amount  sufficient  to  fully
                        compensate  Sublessor  for  any  loss  of or  damage  to
                        Sublessor's residual interest in the Aircraft.

All costs and expenses referred to in the preceding sentence shall be payable by
Sublessee upon demand by Sublessor unless otherwise specified in this Agreement.
All such  obligations  shall survive any  termination  of this  Agreement or the
leasing of the Aircraft or any portion thereof hereunder.

24.5       Cumulative Rights

           Except as otherwise  expressly  provided above, no remedy referred to
           in this  Clause 24 is  intended  to be  exclusive,  but each shall be
           cumulative  and in addition to any other remedy  referred to above or
           otherwise available to Sublessor at law or in equity. The exercise or
           beginning  of  exercise  by  Sublessor  of any  one or  more  of such
           remedies  shall not preclude the  simultaneous  or later  exercise by
           Sublessor  of any or all such other  remedies.  No express or implied
           waiver by  Sublessor of any Event of Default  hereunder  shall in any
           way be, or be construed  to be, a waiver of any future or  subsequent
           Event of Default.

25.        ASSIGNMENT AND TRANSFER

25.1       By Sublessee

           No assignment, novation, transfer or Security Interest may be made by
           Sublessee in any of its rights with respect to the Aircraft,  Engine,
           Parts, this Agreement or the other Transaction  Documents (other than
           Permitted Liens).

25.2       By Sublessor

           Subject to Sublessee's  rights pursuant to this Agreement,  Sublessor
           may at any time and  without  Sublessee's  consent  sell,  assign  or
           transfer  its  rights  and  interest  hereunder  and  under the other
           Transaction  Documents  to a  third  party,  (Sublessor's  Assignee).
           Sublessor  will in good faith  co-operate  with  Sublessee  to ensure
           minimum  practical  disturbance  or  cost  in  connection  with  such
           assignment  or transfer of rights and interest  hereunder.  Sublessee
           agrees to  co-operate  in good  faith  with  Sublessor  in such sale,
           assignment or transfer and provide Sublessor and Sublessor's Assignee
           with such reasonable  assistance as Sublessor may require,  including
           but not limited to assisting in any of  Sublessor's  and  Sublessor's
           Assignee's efforts to minimise or eliminate any Taxes related to such
           assignment or transfer.  For a period of two (2) years after any such
           sale or assignment and at Sublessee's  cost,  Sublessee will continue
           to  name  Owner  Trustee,   Sublessor,  Lender  and  any  Maintenance
           Facilities or parts or equipment  vendors  identified by Sublessor as
           additional insureds in accordance with the insurance requirements set
           out in Clause 21.

25.3       Assignment to Lender



<PAGE>


           Subject to Sublessee's rights under this Agreement, Owner Trustee and
           Sublessor may at any time grant Security  Interests over the Aircraft
           and the benefit of this Agreement,  the other  Transaction  Documents
           and any other  agreement  related  to the  Aircraft  to any lender as
           security  for  Owner  Trustee's  obligations  to such  lender.  Owner
           Trustee's  rights  to grant  any  such  Security  Interests  shall be
           subject only to receipt by Sublessee of an acknowledgment  from or on
           behalf of Lender  relating to quiet  enjoyment  by  Sublessee  of the
           Aircraft as referred to in Clause 25.4.2.

25.4       Sublessee Co-operation

25.4.1     On  request  by  Sublessor,  Sublessor's  Assignee,  Owner Trustee or
           Lender, Sublessee will, at Sublessee's sole expense, promptly execute
           all such documents as Sublessor, Sublessor's Assignee, Owner  Trustee
           or Lender may reasonably require (including such estoppel certificate
           as referred to in Clause  12.4  to  confirm  Sublessee's  obligations
           under  this Agreement and the other Transaction Documents), to obtain
           Sublessee's  confirmation  that no Default is outstanding and for the
           purpose of perfecting and  ensuring and maintaining the perfection of
           any Security Interest granted by Owner Trustee and Sublessor over the
           Aircraft, this Agreement, the  other  Transaction  Documents  or  any
           other  agreement  related  to  the  Aircraft. Sublessee will promptly
           provide   all   other   reasonable  assistance  and  co-operation  at
           Sublessor's expense to Sublessor, Sublessor's Assignee, Owner Trustee
           or Lender in connection with any of the matters referred to  in  this
           Clause 25 or the perfection and maintenance of any  related  Security
           Interest, the making of any necessary changes to the Insurances,  the
           making of any necessary filings and  registrations  in  the  State of
           Incorporation or the State of Registration or the  provision  of  any
           appropriate   counsel's    opinions   in   relation   to  Sublessee's
           obligations.

25.4.2     Sublessor will obtain for the benefit of Sublessee an acknowledgement
           from  Sublessor's  Assignee or Lender that, so long as no Default has
           occurred and is continuing hereunder,  such person will not interfere
           with Sublessee's  quiet,  peaceful use and enjoyment of the Aircraft,
           substantially  in the  form  of  Schedule  11 or such  other  form as
           Sublessor's Assignee or Lender may reasonably require.

25.5       Sublessor Includes Sublessor's Assignee and Lender

           Wherever the term  "Sublessor"  is used in this Agreement in relation
           to any of the provisions relating to registration, title, disclaimer,
           indemnity and insurance  respectively,  the term  "Sublessor" will be
           deemed to include Sublessor's Assignee and Lender.

26.        MISCELLANEOUS PROVISIONS

26.1       Rights Cumulative, Waivers

           The rights of Sublessor under this Agreement are  cumulative,  may be
           exercised  as often as  Sublessor  considers  appropriate  and are in
           addition to  Sublessor's  rights under the general law. The rights of
           Sublessor against  Sublessee or in relation to the Aircraft,  whether
           arising under this Agreement or the general law, shall not be capable
           of being  waived or varied  otherwise  than by an  express  waiver or
           variation in writing;  and in  particular  any failure to exercise or
           any delay in  exercising  any of such  rights  shall not operate as a
           waiver or variation of that or any other such right; any defective or
           partial  exercise of any of such rights  shall not preclude any other
           or further  exercise of that or any other such  right;  and no act or
           course of conduct or negotiation on Sublessor's part or on its behalf
           shall  in any way  preclude  it from  exercising  any  such  right or
           constitute a suspension or any variation of any such right.

26.2       Delegation

           Sublessor  may  delegate  to any person or persons  all or any of its
           rights, powers or discretions vested in it by this Agreement, and any
           such  delegation  may be made upon  such  terms  and  conditions  and
           subject to such  regulations  (including  power to  sub-delegate)  as
           Sublessor in its absolute discretion thinks fit.

26.3       Expenses

           So long  as the  Aircraft  is  tendered  for  Delivery  to  Sublessee
           pursuant  to this  Agreement,  Sublessee  shall pay to  Sublessor  on
           demand:

           (i)          all reasonable  expenses including legal,  professional,
                        and  out-of-pocket   expenses  incurred  or  payable  by
                        Sublessor  in  connection   with  any  amendment  to  or
                        extension  of  or  other   documentation   requested  by
                        Sublessee  in  connection  with,  or the granting of any
                        waiver or consent under this Agreement or the monitoring
                        of compliance by Sublessee with this  Agreement,  but in
                        the case of such monitoring of compliance,  only if upon
                        such  monitoring  Sublessee  is found  to be in  Default
                        under this Agreement; and

           (ii)         all  expenses  including  legal,  survey and other costs
                        payable or incurred by Sublessor  following a Default in
                        connection  with the  enforcement of or  preservation of
                        any of Sublessor's  rights under this  Agreement,  or in
                        respect of the repossession of the Aircraft.

the currency in which they are incurred by Sublessor.

26.4       Time of Essence

           The time  stipulated in this  Agreement for all payments by Sublessee
           to Sublessor  and for the prompt  performance  of  Sublessee's  other
           obligations  under this  Agreement  will be of the  essence  for this
           Agreement.

26.5       Entire Agreement

           The Transaction  Documents are the sole and entire agreements between
           Sublessor  and  Sublessee in relation to the leasing of the Aircraft,
           and supersede all previous agreements in relation to that leasing.

26.6       Further Assurances

           The  parties  shall  take such  action  as  Sublessor  and  Sublessee
           reasonably  consider to be in furtherance of the commercial intent of
           the  parties  under  the  Transaction  Documents  including,  without
           limitation, such action as may be required properly to transfer title
           to engines and parts as  contemplated in this Agreement in compliance
           with the laws of the lex situs of the relevant  engine or part at the
           relevant time.

26.7       Language

           All notices to be given under this Agreement will be in English.  All
           documents  delivered to Sublessor  pursuant to this Agreement will be
           in English or, if not in English,  will be accompanied by a certified
           English  translation.  If  there  is any  inconsistency  between  the
           English  version  of this  Agreement  and any  version  in any  other
           language, the English version will prevail.

26.8       Variation

           The  provisions  of this  Agreement  shall not be  varied or  amended
           otherwise  than by an instrument in writing  executed by or on behalf

26.9       Invalidity of any Provision

           If any  provision  of this  Agreement  becomes  invalid,  illegal  or
           unenforceable  in any respect under any law, the  validity,  legality
           and  enforceability of the remaining  provisions shall not in any way
           be affected or impaired.

26.10      Survival

           All indemnities and other obligations of Sublessee which arise or are
           attributable  to  circumstances  occurring  during the Sublease  Term
           shall survive,  and remain in full force and effect,  notwithstanding
           the expiration or other  termination of this Agreement or the leasing
           of the Aircraft hereunder.

26.11      Reimbursement

           If Sublessee  defaults in the  performance of any of its  obligations
           under this  Agreement that can be rectified by the spending of money,
           Sublessor  shall be entitled  (but not  obliged)  to expend  money to
           rectify such matter and Sublessee shall reimburse Sublessor on demand
           the money so expended.  Any expenditure by Sublessor pursuant to this
           Clause 26.11 shall not  prejudice  the rights of Sublessor in respect
           of any Default or Event of Default.

26.12      Press Releases

           The parties will give copies to one another,  in advance if possible,
           of all news, articles and other releases provided to the public media
           regarding this Agreement or the Aircraft.

26.13      Power of Attorney

           Sublessee hereby  irrevocably  appoints Sublessor as its attorney for
           the  purpose of  putting  into  effect  the intent of this  Agreement
           following  an Event of Default,  including  without  limitation,  the
           return, repossession, deregistration and exportation of the Aircraft.
           To evidence  this  appointment,  Sublessee  has executed the power of
           attorney  in the form of Schedule  8.  Sublessee  will take all steps
           required under the laws of the State of  Registration to provide such
           power of attorney to Sublessor.

26.14      Usury Laws



<PAGE>


           Notwithstanding   anything  to  the   contrary  in  the   Transaction
           Documents, Sublessee will not be obligated to pay Default Interest or
           other interest in excess of the maximum  non-usurious  interest rate,
           as in  effect  from  time to time,  which  may by  applicable  law be
           charged, contracted for, reserved, received or collected by Sublessor
           in connection  with the Transaction  Documents.  During any period of
           time in which the then  applicable  highest lawful rate is lower than
           the  Default  Interest  rate,  Default  Interest  will  accrue and be
           payable at such highest lawful rate;  however, if at later times such
           highest lawful rate is greater than the Default  Interest rate,  then
           Sublessee will pay Default  Interest at the highest lawful rate until
           the Default  Interest which is paid by Sublessee equals the amount of
           interest  which  would  have  been  payable  in  accordance  with the
           interest rate set forth in Schedule 2.

26.15      Confidentiality

           The Transaction Documents and all non-public  information obtained by
           either  party  about  the  other  are  confidential  and are  between
           Sublessor  and  Sublessee  only and the  commercial  terms  and other
           material  provisions  of this  Agreement  will not be  disclosed by a
           party to third parties (other than to such party's auditors,  lenders
           and legal  advisors)  without the prior written  consent of the other
           party except in connection with enforcement of rights  hereunder.  If
           disclosure is required as a result of applicable  law,  Sublessee and
           Sublessor  will  co-operate  with one another to obtain  confidential
           treatment as to the commercial terms and other material provisions of
           this Agreement;  provided, however, if they are unable to obtain such
           confidential  treatment and disclosure is required by applicable law,
           then such disclosure may be made in accordance with such law.

26.16      Counterparts

           This   Agreement   may  be  executed  in  any  number  of   identical
           counterparts, each of which will be deemed to be an original, and all
           of which  together  will be deemed to be one and the same  instrument
           when each party has signed and delivered one such  counterpart to the
           other party. Delivery of an executed counterpart of this Agreement by
           facsimile  will be deemed  effective  as  delivery  of an  originally
           executed counterpart. Any party delivering an executed counterpart of
           this Agreement by facsimile will also deliver an originally  executed
           counterpart;  provided,  however, the failure of any party to deliver
           an originally executed  counterpart of this Agreement will not affect
           the validity or effectiveness of this Agreement.

26.17      Bankruptcy



<PAGE>


           It is the  intention  of the  parties  that  the  Sublessor  shall be
           entitled to the benefits of 11 U.S.C.  1110 with respect to the right
           to repossess the Airframe,  Engines and Parts as provided herein, and
           in any  circumstances  where more than one  construction of the terms
           and  conditions of this Agreement is possible,  a construction  which
           would  preserve  such benefits  shall  control over any  construction
           which would not preserve such benefits or would render them doubtful.
           To the extent consistent with the provisions of 11 U.S.C. 1110 or any
           analogous  section of the Federal  bankruptcy  laws,  as amended from
           time to time,  it is  hereby  expressly  agreed  and  provided  that,
           notwithstanding  any other provisions of the Federal bankruptcy laws,
           as  amended  from time to time , any right of the  Sublessor  to take
           possession of the Aircraft in compliance  with the provisions of this
           Agreement shall not be affected by the provisions of 11 U.S.C. 362 or
           363, as amended from time to time, or any analogous provisions of any
           superseding  statute or any power of the  bankruptcy  court to enjoin
           such taking of possession. This Agreement is a true lease and not one
           intended as security.

           Agreement shall be in writing and shall be delivered  personally,  by

           or federal  court  sitting in New York County for the purposes of any
           suit,  action,  or other proceeding  arising out of this Agreement or

                        the Sublease and the  transactions  contemplated  by the
                        Sublease and the Sublease  constitutes the legal binding
                        obligations  of the  Sublease,  enforceable  against the
