               amount   being  the  "Net  Aircraft

               Article  9.9  hereof, should  Buyer

               automatically     terminate     and
               Bombardier  shall have  no  further

               Bombardier's  right to receive  such

               to make payments when due.

               Bombardier  is obligated  to  return

               U.S. prime rate charged from time to
               time  by  the Chase Manhattan  Bank,
               New  York  Branch, or its successor,
               calculated and compounded monthly. .
               The   five  (5)  day  grace   period
               mentioned above shall not  apply  to
               return  of  any excess payments,  if
               any,  received by Bombardier  toward

     ARTICLE 6  -  DELIVERY PROGRAM

          6.1  The  Aircraft shall be offered  for
               inspection and acceptance to  Buyer
               at    Bombardier's   facility    in
               Montreal, Quebec during the  months
               set  forth in Appendix II  attached
               hereto   (the  "Scheduled  Delivery
               Dates").


          ARTICLE 7  -  BUYER INFORMATION

          7.1  During   the  manufacture  of   the
               Aircraft,  Buyer shall  provide  to
               Bombardier  on or before  the  date
               required    by   Bombardier,    all
               information   as   Bombardier   may
               reasonably  request to  manufacture
               the   Aircraft  including,  without
               limitation,   the   selection    of
               furnishings, internal and  external
               colour schemes.

               Failure  of  Buyer to substantially
               comply with these requirements  may
               result in a reasonable increase  in
               price,  as applicable, a  delay  in
               delivery of the Aircraft, or both.

               may  agree upon taking into account
               the terminating action deadline.

          8.5  The Regulatory Change shall be made
               without additional charge to  Buyer
               unless such Regulatory Change is:

               (b)   required  by any governmental
               law      or     regulations      or
               interpretation thereof  promulgated
               by TC or the FAA which is effective
               subsequent  to  the  date  of  this
               Agreement  but before the  Delivery
               Date and which is applicable to all
               aircraft  in  general  or  to   all
               aircraft  of  the same category  as

               delayed by the incorporation of any
               Regulatory Change, such delay shall

               meaning  of  Article 13 subject  to
               the       limitations      therein.
               Notwithstanding  the  provision  of
               Article    13.2(b),   should    the

          8.7  Bombardier  shall  issue  a  Change
               Order,  reflecting  any  Regulatory
               Change  required to be  made  under
               this  Article  8, which  shall  set
               forth   in  detail  the  particular
               changes  to be made and the effect,
               if  any, of such changes on design,

               binding    upon   the    date    of
               Bombardier's  transmittal  of  such
               Change  Order,  all  in  accordance
               with   this  Agreement.    Although
               Buyer's  consent  to  said   Change
               Order  is  not required, Bombardier
               agrees   to   consult  with   Buyer
               regarding  the change  proposed  by
               Bombardier   to   implement    such
               Regulatory Change.

          8.8  If   the   use   of  any   of   the
               certificates  identified  in   this
               Article  8 are discontinued  during
               the  performance of this Agreement,
               reference   to   such  discontinued
               certificate  shall  be   deemed   a
               reference  to any other certificate
               or  instrument which corresponds to
               such   certificate  or,  if   there
               should   not  be  any  such   other
               certificate  or  instrument,   then
               Bombardier shall be deemed to  have
               obtained      such     discontinued
               certificate(s)  upon  demonstrating
               that    the    Aircraft    complies
               substantially       with        the
               Specification.

               consecutive working days commencing
               on  the Readiness Date in which  to

               in accordance with procedures to be
               mutually agreed to, and flight test
               shall  be  conducted in  accordance
               with     Bombardier's    acceptance

               be  provided to Buyer at  least  30
               days   prior   to   the   Scheduled
               Delivery Date of the First Aircraft

          9.5  If    no    Aircraft   defect    or
               discrepancy is revealed during  the

               with the provisions of Article 9.7.

          9.6  If    any   material   defect    or
               discrepancy  in  the  Aircraft   is
               revealed    by    Buyer's    ground
               inspection  or  flight  test,   the
               defect or discrepancy will promptly
               be  corrected by Bombardier, at  no
               cost to Buyer, which correction may
               occur    during   or   after    the
               Acceptance Period depending on  the
               nature of the defect or discrepancy
               and   of  the  time  required   for
               correction.     To    the    extent
               necessary     to    verify     such
               correction,    Bombardier     shall
               perform  one  (1) or  more  further
               acceptance   flights   or    ground
               inspections      as     applicable.
               Notwithstanding the  provisions  of
               Article  4.2,  should the  Delivery

               reimburse Bombardier for all  costs
               and expenses reasonably incurred by
               Bombardier  as  a  result  of  such
               Buyer's  failure to accept or  take
               delivery of the Aircraft, including
               but   not   limited  to  reasonable

               --------

13.2    (a)   If  Bombardier concludes,  based  on
        its  appraisal  of  the facts  and  normal
        scheduling   procedures,   that   due   to
        Excusable   Delay  it  can  be  reasonably
        anticipated that delivery of the  Aircraft
        will  be  delayed, Bombardier  shall  give
        prompt  written notice to  Buyer  of  such
        delay.   Bombardier  and  Buyer  agree  to
        collaborate  and  to use their  reasonable
        efforts  to  mitigate the impact  of  such
        delays upon the parties.

        (b)   If,  as  a  result of  an  Excusable
        Delay,  delivery of the Aircraft  will  be
        delayed  to  a date beyond the  originally
        Scheduled  Delivery Date  or  any  revised
        date  previously agreed to in  writing  by
        the  parties, Buyer and Bombardier  agree,

        -----------------------------------------
        -----------------------------------------
        ------------------------------
               (c)   In  the event of an Excusable
               Delay-------------------------,  or
               an anticipated Excusable Delay ----
               -----------------------------------
               ---- shall conduct an appraisal  of
               the  facts  and  normal  scheduling
               procedures,  and  if  it  concludes
               that delivery of one or more of the
               Aircraft will be delayed ----------
               -------------------    after    the
               originally Scheduled Delivery  Date
               or  any revised date agreed  to  in
               writing by the parties-------------
               -----------------------------------
               -----------------------------------
               -----------------     may      then
               terminate   this   Agreement   with
               respect to such delayed Aircraft by
               giving written notice -------------
               -----------------------------------
               -----------------------------------
               ------------------
        (d)   If, due to Excusable Delay ---------
        ---------------- delivery of any  Aircraft
        is  delayed  -----------------------------
        after  the Scheduled Delivery Date, either
        party  may  terminate this Agreement  with
        respect   to   such  Aircraft  by   giving
        written   notice  to  the   other   within
        fifteen  (15)  business  days  after   the
        expiration of such -------------- period.

13.3 Termination   under   Article   13.2    shall
     discharge all obligations and liabilities  of
     Buyer  and Bombardier hereunder with  respect
     to  such  delayed  Aircraft and  all  related
     undelivered  items and services, except  that
     Bombardier shall, within --------------------
     -  of  such termination, repay to Buyer,  and
     Bombardier's      sole     liability      and
     responsibility  shall  be  limited   to   the
     repayment  to Buyer, of all advance  payments
     for such Aircraft received by Bombardier less
     any amount due by Buyer to Bombardier.


13.4 The  termination rights set forth in  Article
     13.2  are  in  substitution for any  and  all
     other rights of termination or contract lapse
     arising  by  operation of law  in  connection
     with Excusable Delays.


     ARTICLE 14  -  NON-EXCUSABLE DELAY

          14.1 If  delivery  of  the  Aircraft  is
               delayed  beyond  the  end  of   the
               Scheduled Delivery Date, by  causes
               not  excused  under  Article  13.1,
               this   shall  constitute   a   non-
               excusable  delay (a  "Non-Excusable
               Delay").

          14.2 If  as a result of an Non-Excusable
               Delay,  delivery  of  the  Aircraft
               will  be  delayed to a date  beyond
               the  originally Scheduled  Delivery
               Date or any revised date previously
               agreed   to  in  writing   by   the
               parties,   the  Aircraft   Purchase
               Price  of the Aircraft at delivery,

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



ARTICLE 15  -  LOSS OR DAMAGE

15.1 In  the event that prior to the Delivery Date
     of   any  Aircraft,  the  Aircraft  is  lost,
     destroyed or damaged beyond repair due to any
     cause, Bombardier shall promptly notify Buyer
     in  writing.   Such notice shall specify  the
     earliest date reasonably possible, consistent
     with     Bombardier's    other    contractual
     commitments and production schedule, by which
     Bombardier  estimates it  would  be  able  to
     deliver a replacement for the lost, destroyed
     or  damaged  Aircraft.  This Agreement  shall
     automatically  terminate as to such  Aircraft
     unless Buyer gives Bombardier written notice,
     within   thirty  (30)  days  of  Bombardier's
     notice, that Buyer desires a replacement  for
     such Aircraft.  If Buyer gives such notice to
     Bombardier,  the  parties  shall  execute  an
     amendment  to this Agreement which shall  set
     forth  the Delivery Date for such replacement
     aircraft  and  corresponding new  replacement

18.1 In   the   case  of  any  actual  or  alleged
     infringement of any Canadian or United States
     patent  or,  subject  to the  conditions  and
     exceptions set forth below, any patent issued
     under  the laws of any other country in which
     Buyer  from time to time may lawfully operate
     the   Aircraft  ("Other  Patents"),  by   the
     Aircraft,   or  by  any  system,   accessory,
     equipment or part installed in such  Aircraft
     at  the time title to such Aircraft passes to
     Buyer,  Bombardier shall indemnify,  protect,
     hold   harmless   and  defend   (subject   to
     applicable court procedures) Buyer  from  and
     against    all   claims,   suits,    actions,
     liabilities,  damages  and  costs  (including
     reasonable attorney fees --------------------
     ---------------------------------------------
     --------------------------------------
     resulting  from  the infringement,  excluding
     any   incidental  or  consequential   damages
     (which  include  without limitation  loss  of
     revenue  or  loss of profit)  and  Bombardier
     shall  and as promptly as possible under  the
     circumstances, at its option and expense:

        (a)   procure  for Buyer the  right  under
        such   patent   to    use   such   system,
        accessory, equipment or part; or

        (b)    replace  such  system,   accessory,
        equipment or part with one of the  similar
        nature   and   quality   that   is    non-
        infringing; or

        (c)    modify   such  system,   accessory,
        equipment  or  part  to  make  same   non-
        infringing in a manner such as to keep  it
        otherwise   in   compliance    with    the
        requirements of this Agreement.

        Bombardier's  obligation  hereunder  shall
        extend  to Other Patents only if from  the
        time  of  design of the Aircraft,  system,
        accessory,  equipment or  part  until  the
        alleged infringement claims are resolved:

        (d)   such  other country and the  country
        in   which  the  Aircraft  is  permanently
        registered  have ratified and  adhered  to
        and  are  at  the time of  the  actual  or
        alleged  infringement contracting  parties
        to     the    Chicago    Convention     on
        International Civil Aviation  of  December
        7,  1944  and  are fully entitled  to  all
        benefits of Article 27 thereof; and

        (e)   such  other country and the  country
        of  registration shall each  have  been  a
        party to the International Convention  for
        the   Protection  of  Industrial  Property
        (Paris  Convention) or have enacted patent
        laws  which  recognize and  give  adequate
        protection  to  inventions  made  by   the
        nationals  of other countries  which  have
        ratified,  adhered to and are  contracting
        parties   to   either  of  the   foregoing
        conventions.

18.2 The  foregoing indemnity does  not  apply  to
     BFE,  or  to avionics, engines or any system,
     accessory,  equipment or part  that  was  not
     manufactured to Bombardier's detailed  design
     or  to  any  system, accessory, equipment  or
     part   manufactured  by  a  third  party   to
     Bombardier's    detailed    design    without
     Bombardier's authorization.  ----------------

18.3 Buyer's  remedy  and Bombardier's  obligation
     and   liability   under  this   Article   are
     conditional upon (i) Buyer giving  Bombardier
     written  notice  within ten (10)  days  after
     Buyer  receives  notice of a suit  or  action
     against Buyer alleging infringement or within
     twenty  (20)  days after Buyer  receives  any
     other  written  claim  of  infringement  (ii)
     Buyer   uses  reasonable  efforts   in   full
     cooperation  with  Bombardier  to  reduce  or
     mitigate any such expenses, damages, costs or
     royalties involved, and (iii) Buyer furnishes
     promptly  to Bombardier all data, papers  and
     records   in   its  possession   or   control
     necessary  or  useful to  resist  and  defend
     against  such claim or suit.  Bombardier  may
     at  its option conduct negotiations with  any
     party claiming infringement and may intervene
     in  any  suit  or  action.   Whether  or  not
     Bombardier  intervenes, Bombardier  shall  be
     entitled  at any stage of the proceedings  to
     assume   or  control  the  defense.   Buyer's
     remedy   and   Bombardier's  obligation   and
     liability   are   further  conditional   upon
     Bombardier's   prior  approval   of   Buyer's
     payment  or  assumption of  any  liabilities,
     expenses,  damages, royalties  or  costs  for
     which  Bombardier  may  be  held  liable   or
     responsible.

     consent not to be unreasonably withheld.   In
     the  event of such assignment, sale, transfer
     or disposition Buyer shall remain jointly and
     severally  liable with any assignee  for  the
     performance  of  all  and  any   of   Buyer's
     obligations   under   this   Agreement    and

     provisions and limitations as detailed  Annex

     Liability as defined in Article 19 hereof and
     Indemnity  Against  Patent  Infringement   as
     defined in Article 18 hereof and any other on-
     going obligations of Buyer, which shall apply
     to  it  to  the same extent as if said  third
     party  was Buyer hereunder and provided  that
     there  is no increase to the liability and/or
     responsibility of Bombardier.

20.6 Bombardier  may assign any of its  rights  to
     receive  money  hereunder without  the  prior
     consent of Buyer.

20.7 Notwithstanding the other provisions of  this
     Article 20, Bombardier shall, at Buyer's cost
     and  expense, if so requested in  writing  by
     Buyer,  take  any action reasonably  required
     for   the  purpose  of  causing  any  of  the
     Aircraft to be subjected (i) to, at or  after

     conditional   sale   or  lien,   leases   and
     mortgages, or (ii) to another arrangement for
     the  financing  of  the  Aircraft  by  Buyer,
     providing,   however,  there  shall   be   no

     responsibility of Bombardier arising  through
     such financing.

     operation,       maintenance,       overhaul,
     modification,  storage  and  repair  of   the
     Aircraft  by Buyer or any third party,  Buyer

     Agreement  by means of a notice to the  press

     (the "Securities Act"), and in any such case,
     Buyer   reasonably   determines   that   this
     Agreement   is   a  "material  contract"   as
     described in Item 601 of Regulations S-K, and
     is  required to be filed as an exhibit  to  a
     registration  statement under the  Securities
     Act  or  a periodic report under the Exchange
     Act,  Buyer shall notify Bombardier prior  to
     the  date of such anticipated filing of  such

     under the Exchange Act or Rule 406 under  the
     Securities  Act,  as the case  may  be,  with
     respect  to  information in  this  Agreement,
     which   Buyer  reasonably  believes   to   be
     eligible  for confidential treatment.   Buyer
     agrees  to  provide Bombardier  with  advance
     notice   of  the  information  selected   for
     inclusion  in  its  request for  confidential
     treatment   and   to   reasonably    consider
     recommendations  made by Bombardier  for  the
     inclusion of any additional information. .

     notwithstanding the other provisions of  this
     Article,  portions of this Agreement  may  be
     filed   as   exhibits  to  such  registration
     statement  or periodic report to  the  extent
     determined  to be appropriate to comply  with
     applicable  law  and such  filing  shall  not
     constitute a breach hereof by Buyer.


23.5 Bombardier hereby acknowledges that Buyer  is
     sensitive   with  respect   to   the   public
     disclosure of its operating data provided  to
     Bombardier   pursuant  to   this   Agreement.
     Although    Bombardier    shall    have    no
     confidentiality undertaking with  respect  to
     such  data,  Bombardier  agrees  to  consider
     Buyer's sensitivity in its public use of said
     data.

     shall   have   sixty  (60)  days   from   the
     completion  of  the representations  by  each
     party to issue its recommendations.

25.5 If,  despite the recommendations of the Joint
     Commission, the parties are unable to resolve
     the  Dispute, either party may, except  where
     the  remedies  sought include termination  of

     U.S.A., as agreed between the parties.

25.8 The  arbitrators  shall not act  as  "Amiable
     Compositeur"  and shall decide  according  to
     the terms of the agreement and to the laws of
     New York.

25.9 The  award of the arbitration shall be  final
     and  shall not be called in question  in  any
     court or tribunal.

25.10       It   is  expressly  agreed  that   any
     statement, representation or document made or
     produced to or in connection with,  or  as  a
     result of the formation of a Joint Commission
     shall   be  without  prejudice  and   without
     admission  of liability by either  party  and
     shall not be used as such by the other party.

25.11      Each party shall be responsible for its
     own  costs and expenses incurred as a  result
     of,   or   in   connection  with  the   Joint

     (f)  in  the  event that Bombardier shall  be

          indices  quoted here, are based  on  the
          information known to date and  represent
          the  projection  by  Bombardier  of  the
          manner  in  which Bombardier will  incur
          cost  in the production of the Aircraft.
          In  the  event there is a change in  the
          indices  published or  in  circumstances
          which  materially  affects  the  indices
          chosen  or  the  weighting  assigned  to
          them,  the  indices and/or the weighting
          shall  be amended accordingly by  mutual
          agreement of the parties.  The change in
          circumstances  referred to  above  shall
          include but not be limited to:

     1)   Any  material change in the  basis  upon
          which  the  chosen  indices  have   been
          calculated or if any of said indices are
          discontinued    or    withdrawn     from
          publication,

          Adjustment Formula used in a  Vendor  or
          sub-contractor contract with Bombardier;
          and

          In   the  calculation  of  the  Aircraft
          Purchase  Price the following guidelines
          in   respect  of  decimal  places  shall
          apply:

     (a)  All  indices in the Economic  Adjustment
          Formula  shall be rounded to the  second
          decimal place,

     (b)  The Economic Adjustment Formula shall be
          calculated  and rounded to four  decimal
          places, and

       circumstances pertaining thereto.

1.5            Intentionally Left Blank .

1.6            Timely Corrections

     Bombardier  shall  make  the  repair,  replacement   or
     rework,  following  receipt of the  defective  part  or
     item, with reasonable care and dispatch.

     In  the  event  that  Bombardier does  not  respond  or
     confirm receipt of a warranty claim from Buyer --------
     -------------------------------------------------------
     ------- subject to Buyer and Bombardier agreeing  on  a
     non-receipt of a confirmation from Bombardier within --
     -------- from the date of submittal of claim.


1.7  Labour Reimbursement

     For correction of Defects Bombardier shall establish  a
     reasonable  estimate for the labour hours required  for
     the  repair,  replacement or rework  of  the  defective
     Bombardier  Part  and,  if the repair,  replacement  or
     rework  is  performed by Buyer or  by  third  party  on
     behalf  of Buyer, Bombardier shall reimburse Buyer  for
     Bombardier  estimated  hours or for  Buyer's  or  third
     party's actual labour hours, whichever is less, for the
     repair,   replacement  or  rework  of   the   defective
     Bombardier  Part excluding any work necessary  to  gain
     access  to  said  Bombardier Part.  Such  reimbursement
     shall  be  based  upon Buyer's direct labour  rate  per
     manhour  plus  burden  rate  of  fifty  percent  (50%),
     subject to annual review and adjustment of such  labour
     rate  as mutually agreed; provided, however, that  this
     amount  shall  not exceed fifty percent  (50%)  of  the
     Bombardier published selling labour rate.

1.8  Approval, Audit, Transportation and Waiver

     All  Warranty  claims  shall be subject  to  audit  and
     approval by Bombardier.  Bombardier will use reasonable
     efforts to advise in writing the disposition of Buyer's
     Warranty  claim within thirty (30) days  following  the
     receipt of the claim and (if requested) return  of  the
     defective  Bombardier  Part to Bombardier's  designated
     facility.    Bombardier   shall   notify    Buyer    of
     Bombardier's disposition of each claim.

     Buyer  shall  pay  all costs of transportation  of  the
     defective   part   from  Buyer  to  Bombardier's   U.S.
     distribution centre and Bombardier shall pay all  costs
     of   transportation  of  the  repaired,  corrected   or
     replacement parts back to Buyer.
1.9            Limitations

     1.9.1      Bombardier  shall be relieved of  and  shall
          have   no  obligation  or  liability  under   this
          Warranty if:

          a)the  Aircraft was operated with any products  or
            parts  not  specifically approved by Bombardier,
            unless   Buyer  furnishes  reasonable   evidence
            acceptable  to Bombardier that such products  or
            parts were not a cause of the Defect; or

          b)the  Aircraft was not operated or maintained  in
            accordance  with the Technical  Data  listed  in
            Attachment  A  of Annex A and the manufacturer's
            documentation  furnished  to  Buyer   (including
            Service  Bulletins and airworthiness directives)
            unless   Buyer  furnishes  reasonable   evidence
            acceptable to Bombardier that such operation  or
            maintenance was not a cause of the Defect; or

          c)the  Aircraft  was  not  operated  under  normal
            airline  use, unless Buyer furnishes  reasonable
            evidence  acceptable  to  Bombardier  that  such
            operation was not a cause of the Defect; or

          d)Buyer does not

            1)report  the  Defect in writing to Bombardier's
               Warranty administrator within forty-five (45)
               calendar  days following such Defect becoming
               apparent, and

            2)retain  the  Bombardier  Part  claimed  to  be
               defective  until  advised  by  Bombardier  to
               return  such  Bombardier Part to Bombardier's
               designated  facility in order for  Bombardier
               to  finalize  its evaluation of the  Warranty
               claim   or  to  otherwise  dispose  of   such
               Bombardier Part; or

          e)Buyer  does  not submit reasonable demonstration
            to  Bombardier  within forty-five (45)  calendar
            days after the Defect becomes apparent that  the
            Defect  is  due to a matter covered within  this
            Warranty; or

          f)Buyer   does  not  allow  Bombardier  reasonable
            opportunity  (taking into account  Buyer's  wish
            to  replace  Aircraft back  in  service)  to  be
            present  during  the disassembly and  inspection
            of the Bombardier Part claimed to be defective.

     1.9.2      The  above warranties do not apply to  Buyer
          Furnished Equipment.

1.10 Normal Usage

     Normal   wear  and  tear  and  the  need  for   regular
     maintenance and overhaul shall not constitute a  Defect
     or failure under this Warranty.

1.11 Overhaul of Warranty Parts

     Bombardier's liability for a Bombardier Part which  has
     a Defect and is overhauled by Buyer within the Warranty
     Period  shall  be limited only to that portion  of  the
     labour and material replacement related to the Defect.

1.12 No Fault Found

     In  the  event that a Bombardier Part returned under  a
     Warranty  claim  is  subsequently  established  to   be
     serviceable then Bombardier shall be entitled to charge
     and  recover  from  Buyer  any  reasonable  inspection,
     transportation,  repair and other costs  of  a  similar
     nature  incurred by Bombardier in connection with  such
     Warranty claim.  Providing, however, in the event  that
     repetitive  in-service failure occurs on the particular
     Bombardier  Part  which is subsequently  identified  by
     Bombardier on a repeated basis to be "no fault  found,"
     then  Bombardier and Buyer shall discuss  and  mutually
     agree  a course of further action to help identify  the
     problem.    In  the  event  the  fault  is   ultimately
     confirmed  to be a legitimate Warranty claim  then  the
     above  mentioned costs, if incurred by Bombardier  will
     be borne by Bombardier, and any such costs already paid
     by Buyer will be reimbursed by Bombardier.


ARTICLE 2 - VENDOR WARRANTIES

2.1  Warranties from Vendors

     The  Warranty  provisions of  this  Annex  B  apply  to
     Bombardier  Parts only.  However, Bombardier  has  made
     or  shall  make reasonable efforts to obtain favourable
     warranties  from vendors, with respect to Vendor  Parts
     and   Power   Plant  Parts.   Except  as   specifically
     provided  under  this  Annex B  Article  2,  Bombardier
     shall have no liability or responsibility for any  such
     Vendor  Parts and Power Plant Parts and the  warranties
     for  those Vendor Parts and Power Plant Parts shall  be
     the  responsibility  of  the vendor  and  a  matter  as
     between Buyer and vendor.

2.2  Vendor Warranty Backstop

     For  those  Vendor Parts installed on the  Aircraft  at
     the  Delivery  Date  or subsequently purchased  through
     Bombardier,  excluding  the  Powerplant  or  the  Power
     Plant  Parts,  in the event the parties  agree  that  a
     vendor  is  in  default  in  the  performance  of   any
     material   obligation  under  any  applicable  warranty
     obtained  by  Bombardier from such vendor  pursuant  to
     Annex  B  Article  2.1 above, the  warranties  and  all
     other  terms and conditions of Annex B Article 1  shall
     become  applicable as if the Vendor Parts  had  been  a
     Bombardier Part, except that the warranty period  shall
     be  the  Warranty Period as set forth herein or by  the
     vendor's warranty, whichever is shorter.

2.3  Bombardier's Interface Commitment

     In  the  event  of  a dispute in the application  of  a
     Vendor  Part warranty, at Buyer's request addressed  to
     Bombardier's warranty administrator, Bombardier  shall,
     without  charge, conduct an investigation and  analysis
     of   any   such  dispute  resulting  from  a  technical
     interface problem to determine, if possible, the  cause
     of  the  interface problem and then recommend  feasible
     corrective  action.  Buyer shall furnish to  Bombardier
     all   data   and  information  in  Buyer's   possession
     relevant  to the interface problem and shall  cooperate
     with  Bombardier  in the conduct of  its  investigation
     and  such tests as may be required.  Bombardier, at the
     conclusion of its investigation, shall advise Buyer  in
     writing of Bombardier's opinion as to the cause of  the
     problem   and   Bombardier's   recommended   corrective
     action.

            not  apply  to any Aircraft which has  not  been
            correctly  modified  in  accordance   with   the
            specifications or instructions contained in  the
            relevant  Service Bulletins which are  furnished
            to  Buyer  prior  to receipt by Bombardier  from
            Buyer  of  any  notice  of an  occurrence  which

               ----------------------------------------
               -------------------------------
          (v)  In  all  cases,  prior to  notice  being
               received  by  Bombardier from  Buyer  of
               Buyer's   formal   acceptance   of   the
               rescheduled  delivery  position(s),  any
               rescheduled     delivery     position(s)
               provided  from Bombardier to Buyer  will
               be  subject to prior sale, commitment or

               aircraft.

          (vi) Buyer's  failure to exercise its  rights
               with  respect  an Option Aircraft  shall

               Aircraft which have been rescheduled  by

               Excusable  Delay, as defined in  Article
               13 of the Agreement) to a delivery month
               beyond  October  2003 will  increase  to
               reflect  price changes to  the  aircraft
               standard  base  price (list  price),  if
               any,   as   a  result  of  value   added
               modifications incorporated  as  standard
               into  the Option Aircraft from the  date
               of the execution of the Agreement to the
               date   of  exercise  of  the  applicable
               Option Aircraft.

          (viii)      Buyer   will  endeavor  to   keep

               regarding    rescheduling   of    Option
               Aircraft.

               delivery of each Option Aircraft, at  no
               additional  charge to Buyer, extend  the

Gentlemen,


          Letter   Agreement  No.   004   to   Purchase
          Agreement  No.  PA-0454 dated July  29,  1999
          (the  "Agreement")  between  Bombardier  Inc.
          ("Bombardier")  and Atlantic  Coast  Airlines
          ("Buyer") relating to the purchase of six (6)
          Canadair    Regional   Jet   Aircraft    (the
          "Aircraft")



          Subject:       Financing

     1.0  This  letter constitutes an integral part  of
          the   Agreement  and  evidences  our  further
          agreement  with the matters set forth  below.
          All  terms  used herein and in the  Agreement
          and  not defined herein, shall have the  same
          meaning as in the Agreement.

          1.1  This  Letter  Agreement  describes   the
               general  terms  and  conditions  of  the
               financing  assistance to be provided  by
               Bombardier to Buyer.  ------------------

     2.0  Financing Assistance

          2.1  Financing assistance referred to in this
               Letter  Agreement No.  004  shall  apply
               only    to    the   Financed   Aircraft.
               Financing for the Financed Aircraft will
               be   arranged   by  Buyer   working   in
               coordination with Bombardier.  The  form
               of  any support which may be provided by
               Bombardier   is   to   be   treated   as
               confidential and is not to  be  provided
               by  Buyer to any third party without the
               third   party   executing   Bombardier's
               confidentiality   agreement.    It    is
               Buyer's responsibility to have such form
               executed  with any third party prior  to
               Buyer's    disclosure   of   any    such
               information and to provide such form  to
               Bombardier for approval.  The above does
               not  apply where Buyer or the applicable
               third party is required to disclose such
               information by law or compelled by court
               order to do so.
