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

that BRAD
has met all of its obligations under this Article 9, should

following the end of the Acceptance Period, BRAD may, at its
option, terminate
the present Agreement with respect to any of the undelivered
Aircraft.  BRAD
shall however, have the option (but not the obligation) of

*



13.2 (a)  If BRAD 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, BRAD shall give prompt written notice to Buyer of
such
delay.  BRAD and Buyer agree to collaborate and to use their
reasonable efforts
to mitigate the impact of such delays upon the parties.


     (b)  If, as the result of an
Excusable Delay, delivery of the
Aircraft will be delayed to a date

and normal
scheduling procedures, and if it concludes that delivery of
one or more of

then terminate this
Agreement with respect to such delayed Aircraft by giving
written notice  *

Aircraft is
delayed for  *  after the Scheduled Delivery Date, either
party may terminate this Agreement with respect to  such

such notice
to BRAD, the parties shall execute an amendment to this
Agreement

this
Agreement applicable to the replaced Aircraft shall apply to
the
replacement aircraft.

termination of this Agreement, to which BRAD shall be
entitled,  *  and

     (d)  *



16.4 Notwithstanding the foregoing, nothing herein contained
shall, in the
event of termination of this Agreement, limit  *  ongoing
rights and obligations
with respect to Aircraft delivered prior to the termination

obligation contained in Letters of Agrement where it is
expressly
provided that said obligations (or part thereof) shall

APPENDIX I

REGIONAL JET AIRCRAFT
ECONOMIC ADJUSTMENT FORMULA

Pursuant to the provision of Article 4 of the Agreement,
economic
adjustment will be calculated using the lesser amount of
those generated by
the following two calculations:

        (i)    The Economic Adjustment Formula:


PP  =  PO (0.28     LD + 0.35    ED + 0.20   CD + 0.15 MD +
0.02 FD)
              LO          EO       CO        MO        FO

 *




Where:

PP  =     Aircraft Purchase Price;

PO  =     Base Price;

LD  =     the Canadian labour index based upon the indices
for the last full
month preceding the month of delivery of the relevant
Aircraft;

LO  =     the Canadian labour index which, as at 1 July
1995, is 19.69;

ED  =     the U.S. labour index based upon the indices for
the last full month
preceding the month of delivery of the relevant Aircraft;

EO  =     the U.S. labor index which, as at 1 July 1995, is
18.07;

CD  =     the Industrial Commodities index based upon the
indices for the last
full month preceding the month of delivery of the relevant
Aircraft;

CO  =     the Industrial Commodities index which, as at 1
July 1995, is 126.6;

MD  =     the material index based upon the indices for the
last full month
preceding the month of delivery of the relevant Aircraft;

MO  =     the material index which, as at 1 July 1995, is
134.8;

FD  =     the fuel index based on the indices for the last
full month preceding
the month of delivery of the relevant Aircraft; and

FO  =     the fuel index which, as at 1 July 1995, is 81.0.

For the purpose of the Economic Adjustment Formula and the
calculation of the
economic adjustment:

(a)  the Canadian labour index shall be the index provided
in the Standard
Industrial Classification (S.I.C.) Code 321 for Average
Hourly
Earnings for the Aircraft and Parts Industry (Canada)
published by
Statistics Canada in "Employment Earnings and Hours" Table
3.1.

(b)  the U.S. labour index shall be the index provided in
the Bureau of
Labor Statistics (B.L.S.) Code 372 Gross Hourly Earnings of
production and non-supervisory workers in the Aircraft and
Aircraft
Parts Industry as published by the U.S. Department of Labor,
Bureau
of Labor Statistics in "Employment and Earnings" Table C-2.

(c)  the Industrial Commodities index shall be the index
provided in the
Producer Price Index as Industrial Commodities as published
by the
U.S. Department of Labor, Bureau of Labor Statistics in
"Producer
Prices and Price Indexes" Table 6.

(d)  the material index shall be the index provided in the
Producer Price
Index for Code 10 Metals and Metals Products as published by
the U.S.
Department of Labor, Bureau of Labor Statistics in "Producer
Prices
and Price Indexes" Table 6.

(e)  the fuel index shall be the index provided in the
Bureau of Labor
Statistics (B.L.S.) Code 5 "Fuel and Related Products and
Power"
Table 6 as published by the U.S. Department of Labor.

(f)  in the event that BRAD shall be prevented from
calculating the
Aircraft Purchase Price of each Aircraft due to any delay in
the
publication of the required indices, BRAD shall use the last
provisionally published indices, and in the event that
provisional
indices are not available, BRAD shall extrapolate from the
last three
(3) months of published indices and where the balance of the
Aircraft
Purchase Price payable is calculated on the provisionally
published
indices, and/or extrapolation, BRAD will amend such
installment on
publication of the final indices and will submit
supplementary claims
or provide credit notes in respect of any adjustment so
caused.

     Notwithstanding the foregoing, it is the intention of
the parties to
finalize the Aircraft Purchase Price within twelve (12)
months
following the Aircraft delivery date.  Accordingly, at the
end of
each calendar quarter the parties shall review and finalize
by mutual
agreement the Aircraft Purchase Price of the Aircraft
delivered more


than twelve months prior to such review, using the best data
and
information available at that time.

(g)  the indices used in the Economic Adjustment Formula and
the weighting
assigned to them, as well as the various indices as of July
1st, 1995
quoted here, are based on the information known to date and
represent
the projection by BRAD of the manner in which BRAD 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,

2)   Any change in manufacturing plan involving the letting
of a new sub-
contract or the termination of an existing sub-contract, and

3)   Any change in the escalation or Economic Adjustment
Formula used in a
Vendor or sub-contractor contract with BRAD; 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

(c)  The Aircraft Purchase Price resulting from the Economic
Adjustment
Formula shall be rounded to the nearest dollar.

1.9  Limitations

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

1.11 Overhaul of Warranty Parts

     BRAD's liability for a BRAD 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 BRAD Part returned under a Warranty
claim is
subsequently established to be serviceable then BRAD shall
be
entitled to charge and recover from Buyer any reasonable
inspection, transportation, repair and other costs of a
similar
nature incurred by BRAD in connection with such Warranty
claim.
Providing, however, in the event that repetitive in-service
failure occurs on the particular BRAD Part which is
subsequently
identified by BRAD on a repeated basis to be "no fault
found,"
then BRAD 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 BRAD will be
borne
by BRAD, and any such costs already paid by Buyer will be
reimbursed by BRAD.

Parts
and Power Plant Parts.  Except as specifically provided
under this
Annex B Article 2, BRAD shall have no liability or
responsibility

     In the event of a dispute in the application of a
Vendor Part
warranty, at Buyer's request addressed to BRAD's warranty
administrator, BRAD 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 BRAD all data and
information in
Buyer's possession relevant to the interface problem and
shall
cooperate with BRAD in the conduct of its investigation and
such
tests as may be required.  BRAD, at the conclusion of its

C    =    BRAD's then current price for the Covered
Component;
T    =    The total time to the nearest month since the
Aircraft
containing the Covered Component,  *  was delivered by BRAD



3.4  Conditions and Limitations

3.4.1     The following general conditions and limitations

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 BRAD from Buyer of
any notice of an occurrence which constitutes a failure
in a Covered Component, subject to Buyer having had
reasonable time to i) obtain parts required for the
installation of the Service Bulletin and ii) incorporate
the Service Bulletin into the Aircraft.  The provisions
of this subparagraph shall not apply in the event that
Buyer furnishes reasonable evidence acceptable to BRAD
that such failure was not caused by Buyer's failure to so
modify the Aircraft;

f)   this SLP shall not apply to a failure of a Covered
Component if BRAD determines that such failure may not
reasonably be expected to occur on a repetitive basis
unless subsequently demonstrated to be; and



g)   this SLP shall not apply to a Covered Component where

     design and/or manufacturing of the
     Canadair Regional Jet Aircraft
     (taking into account the state of
     the art at the time of design or
     manufacture) that results in a
     grounding or operational
     restrictions on all or part of
     Buyer's fleet of Aircraft (except
     where directed at Buyer or
     resulting from Buyer's operating or
     maintenance practices), which

     operating the Aircraft in revenue
     service for more than  *  or

(b)  Buyer is prevented from operating
     the Aircraft in revenue service for
     more than  *  by a court order in
     the case of a patent infringement
     claim or action filed before a
     court in Canada or the United
     States,  *



3.0  During the time that Buyer is prevented from operating
the Aircraft due to
such operational restrictions, Buyer shall use best efforts
to reschedule the
Aircraft within its total route system such that the
restriction does not
prevent the Aircraft from operating in revenue service.

4.0  The undertaking by BRAD in this Letter Agreement
excludes any such grounding
or operational restriction caused by:


(i)  BFE or Buyer-selected equipment or other products or
parts not
specifically approved by BRAD;

(ii) failure by Buyer (subject to parts availability) to
comply with or
incorporate a service bulletin which would have prevented
the
grounding;

(iii)     failure by Buyer to comply with the conditions of
the Airworthiness
Directive, within a reasonable length of time given the
availability
of BRAD Parts, Vendor Parts or Powerplant Parts;

(iv) modifications made to the Aircraft or its Vendor Parts
subsequent to
the Delivery Date by Buyer or a third party, unless approved
by BRAD;

(v)  failure to operate or maintain the Aircraft in
accordance with the
Technical Data; or

(vi) not operating the Aircraft in normal commercial airline
service.



5.0       The term of this Letter Agreement shall commence
on the date of start of
revenue service of Buyer's first Aircraft and shall expire
*


6.0  Without limitation to the foregoing, during any period
of grounding or
operational restrictions, BRAD will diligently work to
correct the cause(s)
relating thereto and Buyer will provide all reasonable
assistance, if
required.

7.0  Limitation

7.1  *





8.0  The provisions of this Letter Agreement are personal to
Buyer and
shall not be assigned or otherwise disposed of by Buyer
except as
part of an assignment of the Agreement without the prior
written
consent of BRAD.

9.0  This Letter Agreement constitutes an integral part of
the
Agreement and subject to the terms and conditions contained
therein.

10.0 In the event of Termination of the
Agreement, this Letter Agreement shall
become automatically null and void
unless this Agreement is terminated by
Buyer pursuant to Article 16.1 or 16.2
as a result of a default or breach of
this Agreement by BRAD, or as a result
of an Excusable Delay  *  in which event
the terms and conditions of this
Aircraft will continue to apply to the
Aircraft delivered prior to the date of
termination.



Should there be any inconsistency between this Letter
Agreement and the
Agreement with respect to the subject matter covered by the
terms
hereof, then this Letter Agreement shall prevail.
