COMAIR HOLDINGS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The consolidated financial statements included herein have been prepared by the
Company, without audit, pursuant to the rules and regulations of the Securities
and Exchange Commission. These statements reflect all adjustments which are, in
the opinion of management, necessary for a fair presentation of the results for
the interim periods presented. Certain information in footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles has been condensed or omitted pursuant to such
rules and regulations, although the Company believes that the following
disclosures are adequate to make the information presented not misleading. It is
suggested that these consolidated financial statements be read in conjunction
with the financial statements and the notes thereto included in the Company's
latest annual report on Form 10-K.

NOTE 1: The accounts of Comair Holdings, Inc. and its wholly-owned
        subsidiaries (the Company) have been consolidated in the accompanying
        financial statements. Upon consolidation, all material intercompany
        accounts, transactions and profits have been eliminated. The Company
        considers the transportation of passengers and freight in scheduled
        airline service by its major subsidiary, COMAIR, Inc., to be its
        predominant industry segment. The Company's stock is traded in the
        Nasdaq/National Market System under the symbol COMR.

NOTE 2: Results of operations for the interim periods are not necessarily
        indicative of results to be expected for the year.

NOTE 3: In the third quarter of fiscal 1998, the Company adopted Financial
        Accounting Standards Board Statement No. 128 (SFAS No. 128), "Earnings
        Per Share", which replaces the presentation of primary earnings per
        share with a presentation of basic earnings per share. It also requires
        dual presentation of basic and diluted earnings per share on the face of
        the income statement for all entities with complex capital structures
        and requires a reconciliation of both the numerator and denominator of
        the basic earnings per share computation for the same components in the
        diluted earnings per share computation. The following tables show the
        amounts used in computing earnings per share and the effect on income
        and the weighted average number of shares for the quarters and nine
        months ending December 31, 1997 and 1996 of dilutive potential common
        stock.

COMAIR HOLDINGS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

NOTE 4: In July 1997, the Financial Accounting Standards Board issued
        Statement No. 130 (SFAS No. 130), "Reporting Comprehensive Income",
        which requires that comprehensive income and the associated income tax
        expense or benefit be reported in a financial statement with the same
        prominence as other financial statements with an aggregate amount of
        comprehensive income reported in that same financial statement. SFAS No.
        130 permits a statement of financial position, a statement of changes in
        shareholders' equity, or notes to the financial statements to be used to
        meet this requirement. "Other Comprehensive Income" refers to revenues,
        expenses, gains and losses that under GAAP are included in comprehensive
        income but bypass net income. The Company will adopt SFAS No. 130 in the
        first quarter of fiscal 1999. The Company anticipates the impact of this
        adoption to be immaterial.


NOTE 5: In July 1997, the Financial Accounting Standards Board issued
        Statement No. 131 (SFAS No. 131), "Disclosures About Segments of an
        Enterprise and Related Information" which requires disclosures for each
        segment in which the chief operating decision maker organizes these
        segments within a company for making operating decisions and assessing
        performance. Reportable segments are based on products and services,
        geography, legal structure, management structure and any manner in which
        management disaggregates a company. The Company will adopt SFAS No. 131
        in the first quarter of fiscal 1999. The Company anticipates the impact
        of this adoption to be immaterial.

NOTE 6: On October 23, 1997, the Board of Directors of Comair Holdings, Inc.
        approved a 3-for-2 split in the stock of Comair Holdings, Inc., pursuant
        to which shareholders of record received one share of newly issued stock
        for each two shares of stock currently held. The common stock split was
        payable on November 13, 1997 to shareholders of record at the close of
        business on November 3, 1997. The share and per share financial
        information contained in the accompanying financial statements does give
        effect to the stock split. The cash dividend of $.06 per share, declared
        by the Board of Directors of Comair Holdings, Inc. on October 14, 1997,
        for shareholders of record on November 3, 1997, payable on November 13,
        1997, was paid on a pre-split basis.

COMAIR HOLDINGS, INC. AND SUBSIDIARIES
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS
- ---------------------
         COMAIR, Inc. (COMAIR) is the principal subsidiary of Comair Holdings,
Inc. (with its subsidiaries, the Company), accounting for 96% of the third
quarter operating revenues and expenses. Although the following discussion and
analysis entails various aspects of the Company's financial performance, many of
the factors that affect year to year comparisons relate solely to COMAIR.

         Inflation and changing prices have not had a material effect on
COMAIR's operations because revenues and expenses generally reflect current
price levels. COMAIR's market area, strong financial position and strong cost
control efforts have helped lessen the effect on the Company of price
competition and resulting low fares when compared to many others in the airline
industry. However, changes in the pricing strategies and increased competition
from other airlines could impact COMAIR's ability to recoup future cost
increases through higher fares.

         COMAIR operates as a "Delta Connection" carrier under a ten-year
marketing agreement with Delta Air Lines, Inc. dated and effective in October of
1989. The agreement may be terminated by either party on not less than one
hundred eighty (180) days' advance written notice. Delta owns approximately 21%
of the Company's outstanding common stock, leases reservation equipment and
terminal facilities to COMAIR, and provides certain services to COMAIR including
reservations and passenger and aircraft handling services. Approximately 43% of
COMAIR'S passengers in the third quarter of fiscal 1998 connected to Delta. The
Company has historically benefited from its relationship with Delta. However,
the Company's results of operations and financial condition could be adversely
impacted by Delta's decisions regarding routes and other operational matters, as
well as, any material interruption or modifications in this arrangement.

         For the third quarter of fiscal 1998, the Company reported record
operating revenues. Operating revenues for the third quarter increased to $163.2
million, up 18% from the $138.3 million reported in the third quarter of fiscal
1997.

COMAIR HOLDINGS, INC. AND SUBSIDIARIES
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (continued)

         Operating income, net income and net income per share for the third
quarter of fiscal 1998 all increased when compared with the results reported in
the third quarter of fiscal 1997. Operating income for the quarter rose 57% to
$37.9 million from $24.1 million. Net income increased 57% to $24.3 million from
$15.5 million, while diluted earnings per share increased 57% to $.36 per share
from $.23 per share.

         The increase in earnings is largely the result of increased passenger
enplanements which has translated into higher load factors. Passenger
enplanements and revenue passenger miles (RPMs)in the third quarter grew 19%
over last year's third quarter levels while quarterly load factors exceeded last
year by approximately six percentage points. This traffic growth clearly
indicates our continuing success at our Cincinnati hub, which is approximately
80% of our total operations. The combination of Cincinnati's geographic
location, our world class facilities and the passenger appeal of the Canadair
Jets have made Cincinnati one of the nation's preeminent connecting hubs.

         Capacity, available seat miles (ASMs), grew 8% as we continue to
replace turboprop aircraft with new 50-passenger Canadair Jet aircraft.
Currently, approximately 80% of COMAIR'S capacity is generated by the jet
aircraft.

COMAIR HOLDINGS, INC. AND SUBSIDIARIES
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (continued)

        Salaries and related costs have risen in total and on a unit cost basis
from the third quarter of last year. The increase resulted from the additional
personnel hired to enhance operating effectiveness and service the growing
passenger base and additional jet equipment acquired over the past year.
Expenses relating to incentive compensation plans were also higher as a result
of higher pretax earnings.

        Aircraft fuel price per gallon for the third quarter of fiscal 1998 was
approximately seventeen cents lower than in the third quarter of last year.
Total aircraft fuel cost and cost per ASM decreased as lower fuel prices more
than offset the 11% increase in fuel consumption from our additional Canadair
Jet aircraft. Any sudden and significant increase in fuel prices caused by an
outbreak in hostilities in the Middle East or other factors could have an
adverse effect on earnings unless and until the Company could compensate for
such increase by raising fares.

        Maintenance material and repair costs increased in total and on a unit
cost basis. The increase is attributed to higher maintenance costs due to
warranty periods expiring on certain jet aircraft and an increase in the volume
of scheduled and unscheduled inspections being performed on the Canadair Jets.

        Aircraft rent expense remained virtually the same as the expense in the
third quarter of fiscal 1997 related to certain turboprop aircraft, which have
since been returned to their lessors, and the costs associated with the
accelerated return of those aircraft approximately offset the additional expense
generated by the nine Canadair Jets financed with operating leases since the
third quarter of fiscal 1997. Aircraft rent unit cost decreased as a result of
the additional capacity generated by the six Canadair Jet aircraft acquired
through debt financing and working capital since October 1996.

        Other rent and landing fees increased in total and on a unit cost basis
as COMAIR continues to add the larger Canadair Jets.

        Travel agency and credit card commissions increased in total and on a
unit cost basis due to higher unit revenues (revenue per ASM) in this quarter
than in the third quarter of fiscal 1997.

        Other operating expenses increased in total due to higher passenger
related costs associated with the growth in passenger enplanements. The
additional capacity generated by the jet equipment caused these costs to
decreased on a unit cost basis.

AND RESULTS OF OPERATIONS (continued)

        Depreciation and amortization increased in total and on a unit cost
basis. The increase is due to the purchase of six Canadair Jets since October
1996 along with additional support equipment related to the Canadair Jet fleet.

        Investment income in the third quarter of fiscal 1998 was higher than
third quarter of fiscal 1997 due to higher average cash balances available for
investment coupled with higher interest rates on our investments.

        The Company's effective tax rate, which includes federal, state and
local taxes, approximated the statutory rate in the third quarter of fiscal
1998.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

        In the first nine months of fiscal 1998, the Company generated cash from
operating activities of $140.6 million. During the first quarter, the Company
invested $30.0 million in a short-term interest bearing deposit with an aircraft
manufacturer. This deposit, with associated accrued interest, can be called and
returned to COMAIR within thirty (30) days of written notice by COMAIR or
immediately if the manufacturer's credit rating falls below certain thresholds.
During the first nine months, the Company had property and equipment additions
of $45.4 million, predominantly for aircraft and related support equipment.
These additions were financed with working capital. The Company repaid long-term
obligations of $11.0 million and paid cash dividends of $8.0 million. Total
working capital increased to $166.4 million from $119.7 million at March 31,
1997, while the current ratio increased to 2.31 from 1.99. The Company's
long-term debt to equity position was 25% debt, 75% equity at December 31, 1997,
as compared to 31% debt, 69% equity at March 31, 1997.

        In fiscal 1995, the Board of Directors authorized the Company to
repurchase up to 13.8 million shares of common stock from time to time as market
conditions dictate. As of March 31, 1997, the Company had purchased 6.8 million
shares of this authorization at a cost of $37.2 million. The Company has
repurchased an additional 435,000 shares at a cost of approximately $11.6
million through February 12, 1998.

        COMAIR has taken delivery of seven new generation, 50-passenger Canadair
Jet aircraft during the first nine months of fiscal 1998 bringing the total
Canadair Jet fleet to 55. For 20 of these aircraft, the manufacturer agreed to
arrange the lease financing, including the right to return the aircraft after
seven years with no cost to COMAIR other than normal and customary return
provisions related to the condition of the aircraft.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (continued)

Ten aircraft were financed with debt, one was acquired with working capital,
while the other 24 aircraft were financed through operating leases with terms of
up to 16.5 years.

        As of December 31, 1997, COMAIR had scheduled delivery positions for 25
Canadair Jets to be delivered through fiscal 2000, all of which are firm orders.
The aggregate cost of these aircraft, including support equipment and estimated
escalation, will be approximately $486 million. COMAIR also has options for 45
additional jet aircraft, valued at approximately $875 million, including support
equipment and estimated escalation, which could be available for delivery in
fiscal 2000 through fiscal 2002. Some of the options can be converted to
Canadair's 70-seat aircraft.

        COMAIR expects to finance the aircraft described above through a
combination of working capital and lease, equity and debt financing, utilizing
manufacturers' assistance and government guarantees to the extent available.
COMAIR believes that financing will be available at acceptable rates. If COMAIR
is unable to obtain acceptable financing terms, it could be required to modify
its expansion plans.

        On January 9, 1997, Flight 3272 crashed near Detroit, Michigan. There
were no survivors among the 29 passengers and crew members aboard the turboprop
aircraft. The Company is cooperating fully with the National Transportation
Safety Board and all other federal, state and local regulatory and investigatory
agencies in connection with the crash. In May 1997, the NTSB released the
factual data obtained to date related to Flight 3272. The findings to date are
inconclusive. Several lawsuits have been filed against the Company seeking
damages attributable to the deaths of those on Flight 3272, and additional
lawsuits are expected. The Company maintains substantial insurance coverage for
such claims and, at this time, believes that the claims, expenses and litigation
related to this accident will not have a material adverse effect on the
Company's financial condition, cash flows or results of operations.

        The Company has begun to implement a Year 2000 compliance program
designed to ensure that the Company's computer systems and applications will
properly manage dates beyond 1999. The Company believes the costs of modifying
non-compliant computer systems and applications and the implementation of
software enhancements are primarily internal staff costs. The Company intends to
redeploy existing information technology resources and, thus, does not expect to
incur significant incremental costs to implement its Year 2000 program. However,
there can be no assurance that the systems of other parties, upon which the
Company also relies will be modified on a timely basis. The Company's business,
financial condition, or results of operations could be materially adversely
affected by the failure of its systems and applications or those operated by
other parties to properly operate or manage dates beyond 1999.

        In fiscal 1998, additional capital for repayment of long-term
obligations, planned dividend payments and other capital expenditures are
expected to be provided by operations.

        The Company has a $5 million bank line of credit at prime. The line of
credit has not been used since 1985.

        Several of the statements contained in this report are "forward-looking
statements" as that term is defined in federal securities laws. The actual
results could vary materially from those described in those statements. Factors
that could cause actual results to vary are described in detail in our reports
to the Securities and Exchange Commission including Exhibit 99 to our form 10-K
for the period ending March 31, 1997 and are also discussed in the second and
third paragraphs under "Results of Operations."

                            ITEM 1. LEGAL PROCEEDINGS

On August 30, 1996 the Registrant filed a Complaint for declaratory and
injunctive relief entitled COMAIR, INC. v. NATIONAL MEDIATION BOARD and
INTERNATIONAL BROTHERHOOD OF TEAMSTERS in the United States District Court for
the District of Columbia challenging a decision of the National Mediation Board
reopening Case No. R-6433. This matter involves the demand of the International
Brotherhood of Teamsters to represent Comair, Inc. flight attendants and a
finding by the National Mediation Board that a majority of the employees of the
flight attendant craft had not cast ballots in favor of representation.
Subsequently, the National Mediation Board reopened the case, counted additional
ballots and changed its ruling by certifying the International Brotherhood of
Teamsters as collective bargaining representative for the flight attendants of
Comair, Inc. The outcome of the litigation will determine whether the flight
attendants of Comair, Inc. are represented by the International Brotherhood of
Teamsters unless a new election is ordered.

         There are no other material legal proceedings pending involving the
Company, any of its subsidiaries or their property, except proceedings arising
in the ordinary course of business. The Company believes that all such
proceedings are adequately insured.

7.0      CHANGES

         7.1      Other than a Permitted Change as detailed in Article 7.2, or a
                  Regulatory Change as detailed in Article 7.3, any change to
                  this Agreement as may be mutually agreed upon by the parties
                  hereto, shall be made using a change order ("Change Order").
                  Each Change Order shall be prepared substantially in the
                  format attached as Exhibit G hereto. Such Change Order shall
                  identify, to the extent reasonably practical:

                  a.     the effect of the proposed change on the Scheduled
                         Delivery Date;

                  b.     the price and payment terms applicable to the Change
                         Order; and

                  c.     details of any other material provisions of this
                         Agreement which will be affected by the Change Order.

                  Such Change Order shall become effective and binding on the
                  parties hereto when signed by a duly authorized representative
                  of each party.

         7.2      BRAD, prior to the Delivery Date and without a Change Order or
                  Buyer's consent, may:

                  a.     substitute the kind, type or source of any material,
                         part, accessory or equipment by any other material,
                         part, accessory or equipment of like, equivalent or
                         better kind or type; or

                  b.     make such change or modification to the Specification
                         as it deems appropriate to:

                         1)    improve the Aircraft, its maintainability or
                               appearance; or

                         2)    to prevent delays in manufacture or delivery; or

                         3)    to meet the requirements of Article 3, other than
                               for a Regulatory Change to which the provisions
                               of Article 7.3 shall apply,

                  provided that such substitution, change or modification as
                  detailed at a. or b. above shall not affect the Base Price or
                  materially affect the Scheduled Delivery Date or performance
                  characteristics of the Aircraft. Any change made in accordance
                  with the provisions of this Article 7.2 shall be deemed to be
                  a "Permitted Change" and the cost thereof shall be borne by
                  BRAD. The changes in this Article 7.2 will not adversely
                  affect interchangeability and replaceability. Any envisaged
                  change to be made under Article 7.2 b. above which involves a
                  line replacement unit ("LRU") and/or a rotable component will
                  require Buyer's consent. BRAD shall provide Buyer with written
                  notification of such changes as soon as reasonably practical
                  and Buyer shall respond within thirty (30) days thereof. Lack
                  of response by Buyer within this period shall be considered as
                  an approval to the notified change.

         7.3      If any change, addition or modification to the Aircraft is
                  required because of any law or governmental regulation or
                  interpretation thereof by any governmental agency which is
                  effective after the date of this Agreement, but before the
                  Delivery Date, which is applicable to all aircraft in general
                  or to all aircraft of the same category as the Aircraft (a
                  "Regulatory Change"), such Regulatory Change shall be
                  incorporated in the Aircraft before the Delivery Date of such
                  Aircraft or at such other time after the Delivery Date as the
                  parties may agree upon. BRAD shall advise Buyer of such
                  Regulatory Change and Buyer shall pay BRAD a reasonable price
                  for such Regulatory Change.

         7.4      If the Scheduled Delivery Date of the Aircraft is delayed as a
                  result of any cause to which reference is made in this
                  Article, such delay shall be an Excusable Delay.

         8.4      If at any time between receipt of the BFE by BRAD and the
                  Delivery Date, it is mutually agreed that an item of BFE
                  supplied does not meet the standards and requirements of
                  Article 8.3 or its fitment, integration and testing in the
                  Aircraft or Aircraft systems create unreasonable delays in the

                  b.     ensure satisfactory operation of the BFE;

                  c.     furnish or obtain applicable BFE data;

                  d.     perform any adjusting, calibrating, retesting or

                  e.     furnish or obtain any approvals in compliance with the
                         provisions of this Article; or

                  f.     comply with the conditions of Article 8.1 and/or 8.3;

                  BRAD agrees to discuss with Buyer and, where appropriate,
                  agree with Buyer on the steps to be taken to minimize, cure,
                  eliminate or work around the delay, but any delay incurred
                  shall be the responsibility of Buyer and Buyer shall pay to
                  BRAD any costs and expenses reasonably incurred by BRAD due to

                  a.     purchase the BFE ordered by Buyer and/or received by
                         BRAD at the invoice price paid by Buyer; or

11.0       ACCEPTANCE PROCEDURE

           11.1       BRAD shall give Buyer not less than fifteen (15) working
                      days prior notice of the date on which an Aircraft will be
                      ready for Buyer's inspection and/or flight test and
                      acceptance (the "Readiness Date"). Buyer shall then have
                      up to five (5) consecutive working days commencing on the
                      Readiness Date in which to complete said inspection and
                      flight test (such five (5) working day period being the
                      "Acceptance Period").

           11.2       Up to four (4) representatives of Buyer may participate in
                      Buyer's inspection of the Aircraft and two (2)
                      representatives of Buyer may participate in the flight
                      test. During the flight test BRAD shall retain control
                      over the Aircraft, but will execute such demonstration
                      manoeuvres reasonably requested by Buyer and which are
                      within the flight envelope of the Aircraft and covered by
                      BRAD's ground functional and flight test procedures (the
                      "FTP's"). Such flight test shall be carried out for up to
                      two (2) hours or for such additional duration as both
                      parties may reasonably require. Buyer has the right to
                      perform system checks in accordance with the operating
                      limitations contained in the approved manuals of the
                      aircraft.

           11.3       Buyer shall identify to BRAD prior to their arrival the
                      names of Buyer's representatives who will participate in
                      the foregoing inspection and/or flight test and
                      acceptance.

           11.5       If no Aircraft defect or discrepancy is revealed during
                      the inspection and/or the flight test referred to in
                      Article 11.1 and 11.2 above, Buyer shall accept the
                      Aircraft, on or before the last day of the Acceptance
                      Period in accordance with the provisions of Article 11.7.

           11.6       If any material defect or discrepancy in the Aircraft is
                      revealed by Buyer's inspection and/or the flight test, the
                      defect or discrepancy shall be corrected by BRAD, at no
                      cost to Buyer, before the acceptance of the Aircraft by
                      Buyer which acceptance may occur during or after the
                      Acceptance Period depending on the nature of the defect or
                      discrepancy and of the time required for correction. If
                      such correction reasonably requires an additional flight
                      test, such flight test shall be carried out for up to two
                      (2) hours or for such duration as both parties may
                      reasonably require to demonstrate that the defect or
                      discrepancy is cured. Immediately thereafter Buyer shall
                      accept the Aircraft in accordance with the provisions of
                      Article 11.7.

           11.7       Acceptance of the Aircraft shall be evidenced by Buyer's
                      designated representative signing a Certificate of
                      Acceptance for the Aircraft in the form of Exhibit E
                      attached hereto. The date of signature of the Certificate
                      of Acceptance shall be the "Acceptance Date".

           11.8       Buyer shall provide BRAD, prior to the Delivery Date of
                      each Aircraft, suitable evidence of the authority of
                      designated persons to sign, on behalf of Buyer, the
                      Certificate of Acceptance in respect of the Aircraft
                      together with specimen signatures of the persons so
                      authorized.

                      with Article 2 of Exhibit C and, concurrently with receipt
                      thereof, BRAD shall deliver the Aircraft to Buyer and

                      Buyer takes delivery of the Aircraft shall be the
                      "Delivery Date" as evidenced by the execution of a BRAD
                      Bill of Sale and an FAA Bill of Sale as referred to in
                      Article 12.2 hereof.

           11.10      Execution of the Certificate of Acceptance by or on behalf
                      of Buyer shall be evidence that Buyer is deemed to have
                      examined the Aircraft and found it to be in accordance
                      with the provisions of this Agreement.

           11.11      Provided that BRAD has met all of its obligations under
                      Article 11.6, should Buyer not accept, pay for and/or take
                      delivery of any one of the Aircraft within ten (10)
                      calendar days after the Acceptance Period of such
                      Aircraft, Buyer shall be deemed to be in default of the

                      demand, reimburse BRAD for all costs and expenses
                      reasonably incurred by BRAD as a result of Buyer's failure
                      to accept, and/or pay for and/or take delivery of the
                      Aircraft, including but not limited to reasonable amounts
                      for storage, insurance, taxes, preservation or protection
                      of the Aircraft.

                      from BRAD, and Buyer agrees to promptly, but in any event
                      no later than ten (10) working days after receiving such
                      notice, pay same directly to the taxing authority or
                      jurisdiction, or to reimburse BRAD for said tax, duty or
                      assessment, including interest and penalties, or to
                      contest same and assume the defense against imposition
                      thereof at its sole cost and expense (which may require
                      the payment of such tax or duty during the contestation
                      process) and to hold BRAD harmless from any such
                      imposition. If Buyer does not make timely payment directly
                      to the taxing authority or jurisdiction, or proceed with
                      contestation and timely defense, BRAD may pay the asserted
                      tax, duty or assessment, including interest and penalties,
                      and Buyer shall, within thirty (30) calendar days
                      thereafter, reimburse BRAD for any such payment and all
                      reasonable costs and expenses of BRAD (including
                      reasonable attorney's fees).

           14.3       Upon request, either party shall execute and deliver any
                      documents that either party deems necessary or desirable
                      in connection with any exemption from or reduction of or
                      the contestation of or the defence against any imposition
                      of taxes, duties or assessments referred to in Article
                      14.1 above.

           14.4       The obtaining of any import licenses or authorities
                      required to import the Aircraft into any country outside
                      Canada shall be the responsibility of Buyer. BRAD shall,
                      to the extent permitted by law, obtain a Canadian export
                      license, if required to enable Buyer to export the
                      Aircraft from Canada subject to the prevailing export
                      control regulations pertaining at the Delivery Date.

15.0       LOSS OF OR DAMAGE TO AIRCRAFT

           If prior to the Delivery Date an Aircraft is lost, destroyed or in
           BRAD's judgment damaged beyond repair (the "Total Loss Aircraft"),
           BRAD shall promptly, but not later than sixty (60) days thereafter,
           notify Buyer of the earliest date that a replacement aircraft, which
           will reflect the Specification and which will be generally the same
           configuration or specification as the Total Loss Aircraft can
           reasonably be delivered, consistent with BRAD's other contractual
           commitments and production capabilities. Unless Buyer notifies BRAD
           within thirty (30) calendar days after notice of the replacement
           aircraft's scheduled delivery that Buyer desires such replacement
           aircraft, this Agreement may be terminated as to the Total Loss
           Aircraft. In the event of such termination, BRAD's sole liability and
           responsibility shall be limited to the obligation to return to Buyer
           the amounts paid by Buyer to BRAD with respect to the Total Loss
           Aircraft less any amount overdue by Buyer to BRAD under this
           Agreement. If Buyer timely notifies BRAD that it wants such
           replacement aircraft, the parties shall amend this Agreement
           accordingly. Notwithstanding the foregoing, nothing herein shall
           obligate BRAD to offer to deliver a replacement aircraft to Buyer if
           no aircraft are available or the production line is terminated.

           16.1       Subject to the provisions hereinafter set out in this
                      Article 16, BRAD agrees to indemnify, protect, and save
                      harmless Buyer against any liability, losses, damages or
                      expenses excluding any incidental or consequential damages
                      and excluding any liability, losses, damages and expenses
                      or loss of profits in respect of or resulting from any
                      loss of use of the Aircraft (but including cost of
                      replacing the infringement on account of which use of the
                      Aircraft by Buyer is prevented as more fully provided for
                      in Article 16.2 below) resulting from any infringement or
                      alleged infringement of:

                      a.     any Canadian or United States patent; and

                      b.     any patent issued under the laws of any country
                             other than Canada or the United States in which
                             Buyer from time to time may lawfully operate the
                             Aircraft, provided that from time of design of the
                             Aircraft, accessory, equipment or part and until
                             infringement claims are resolved, such country and
                             the country in which the Aircraft is or are
                             permanently registered by Buyer have ratified and
                             adhered to and are at the time of any such actual
                             or alleged infringement contracting parties to the
                             Chicago Convention on International Civil Aviation
                             of December 7, 1944 including, without limitation,
                             Article 27 thereof and the International Convention
                             for the Protection of Industrial Property 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.

                      The foregoing undertaking by BRAD to indemnify, protect
                      and save harmless Buyer shall not apply in respect of BFE.

           16.2       Subject to the provisions set out in this Article 16, if
                      any feature, part, accessory or equipment of the Aircraft
                      becomes the subject of any claim, suit of proceeding for
                      infringement of a patent as provided for in Article 16.1
                      above, or in the event of an adjudication that such
                      feature, part, accessory or equipment of the Aircraft
                      infringes patent as provided for in Article 16.1 above, or
                      if the use, lease or sale of such feature, part, accessory
                      or equipment of the Aircraft is enjoined, BRAD may, within
                      a reasonable period of time, at its option and expense:

                      a.     procure for Buyer the right under such patent to
                             use such feature, part, accessory or equipment of
                             the Aircraft; or

                      b.     obtain for Buyer permission from the appropriate
                             court or tribunal to use the Aircraft; or

                      c.     replace, with Buyer's consent, such feature, part,
                             accessory or equipment of the Aircraft with one of
                             a similar nature and quality that is
                             non-infringing; or

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

           16.3       BRAD shall not be liable with respect to any actual or
                      alleged patent infringement to which this Article would
                      apply unless:

                      a.     in the event of a suit alleging infringement where
                             legal delay to reply is obligatory, Buyer gives
                             BRAD written notice of such suit within twenty (20)
                             calendar days after Buyer receives notice of such
                             suit, or in the event of a written claim alleging
                             infringement where no legal delay to reply is
                             obligatory, Buyer gives BRAD written notice of such
                             claim within reasonable period of time after Buyer
                             receives such written claim;

                      b.     Buyer uses reasonable efforts, in full cooperation
                             with BRAD, to reduce or mitigate any such expenses,
                             damages costs and royalties involved;

                      c.     Buyer furnishes promptly to BRAD all data, papers
                             and records within its possession and any other
                             information or material within Buyer's knowledge or
                             control, necessary or useful to resist and defend
                             against such claim or suit; and

                      d.     Buyer refrains from making any payment and from
                             assuming any obligations, liabilities, expenses,
                             damages, costs and royalties for which BRAD may be
                             held liable, without prior written approval of BRAD
                             (which shall not be unreasonably withheld) or
                             otherwise acting in a manner prejudicial to such
                             suit or claim.

           16.4       BRAD shall have the option at any time and or from time to
                      time to conduct negotiations in its own name, or in the
                      name of Buyer, and to enter into a settlement or
                      settlements with the party or parties involved in the
                      infringement or alleged infringement and to intervene in
                      any suit or claim. Should BRAD intervene in any such suit
                      or claim, it shall be entitled at any stage of
                      negotiations or proceedings to assume, conduct or control
                      the defence thereof. If BRAD assumes such defence and
                      Buyer, in its interest, elects to participate therein, it
                      shall do so at its sole cost and expense.

           16.5       THE INDEMNITIES, OBLIGATIONS AND LIABILITIES ON THE PART
                      OF BRAD IN THIS ARTICLE ARE UNDERTAKEN BY BRAD AND
                      ACCEPTED BY BUYER IN LIEU OF ANY AND ALL OTHER

                      WHICH BRAD MIGHT OTHERWISE BE LIABLE IN RESPECT OF ANY
                      PATENT INFRINGEMENT OR ALLEGED PATENT INFRINGEMENT BY THE
                      AIRCRAFT OR PART THEREOF, OR UNDER ANY PATENT RIGHT OR
                      RIGHT TO PATENT, AND SUCH INDEMNITIES, OBLIGATIONS AND
                      LIABILITIES SHALL NOT BE EXTENDED, ALTERED OR VARIED
                      EXCEPT IN WRITING SIGNED BY BRAD AND BUYER UNDER THE HAND
                      OF THEIR RESPECTIVE DULY AUTHORIZED REPRESENTATIVE.

                             receipt of notice from BRAD specifying such default
                             or breach.

           18.3       In addition, Buyer may terminate this Agreement in whole
                      or in part before the Delivery Date, with respect to any

                      days following receipt of a notice from Buyer specifying

                      hereunder as follows:

                      i)     In the case of Buyer only to a corporation which is

                      and that the assigning party remains jointly and severally

           19.3       Notwithstanding Article 19.2 above, and other than for the
                      purposes of Article 19.5 below, after transfer of title of
                      an Aircraft Buyer may, with BRAD's prior written consent
                      and subject to BRAD's right to amend one or more of the
                      terms and conditions of this Agreement, resell such
                      Aircraft to a third party purchaser, provided said third
                      party agrees in writing with BRAD that BRAD's sole and
                      exclusive obligations and liabilities to said third party
                      shall be those set forth in the basic Airframe warranties
                      and Service Life Policy warranties, as applicable, that
                      BRAD may provide from time to time to other customers and
                      also provided that there is no increase to the liability
                      and/or responsibility of BRAD.

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

           19.5       Notwithstanding the other provisions of this Article 19,
                      either party shall, at the other parties cost and expense,
                      if requested in writing by the other party, take any
                      action reasonably required, including without limitation
                      giving prior written consent to an assignment, for the
                      purpose of causing any of the Aircraft to be subjected, on
                      or after the Delivery Date, to a trust, lease, conditional
                      sale, lien or other arrangement for the financing of the
                      Aircraft, providing, however, there shall be no increase

                      arising through such financing.

21.0       CONFIDENTIAL NATURE OF AGREEMENT

           21.1       This Agreement is confidential between the parties and
                      shall not, without the prior written consent of the other
                      party, be disclosed by either party in whole or in part to
                      any other person or body except insofar as may be
                      necessary for either party to carry out its obligations
                      under this Agreement or by law or as required by financial
                      institutions involved with financing of the Aircraft. If
                      one party is required by legal proceedings or a court
                      order to disclose this Agreement in whole or in part, such
                      party shall promptly notify the other party in order to
                      allow it, if it deems it necessary, to intervene in or
                      contest such legal proceedings or make representations to
                      the court. Without limiting the foregoing, Buyer agrees to
                      request confidential treatment to the maximum extent
                      possible for any material that must be filed with the
                      Securities and Exchange Commission with respect to any
                      contractual clauses and conditions relating to price,
                      delivery positions, price escalation and financing. Buyer
                      agrees to discuss and review with BRAD such material
                      before release to any third party.

           21.2       Except as may be reasonably required for the normal
                      operation, maintenance, overhaul, and repair of the
                      Aircraft, Buyer shall hold confidential all technical data
                      and information supplied by or on behalf of BRAD. Buyer
                      shall not reproduce any technical data or information or
                      divulge the same to any third party without the prior
                      written consent of BRAD.

           21.3       Either party may announce the signing of this Agreement by
                      means of a notice to the press provided that the content
                      and date of the notice has been agreed to by the other
                      party.

24.0       AGREEMENT

           24.1       This Agreement and the matters referred to herein
                      constitute the entire agreement between BRAD and Buyer and
                      supersede and cancel all prior representations, brochures,
                      alleged warranties, statements, negotiations,
                      undertakings, letters, memorandums of agreement,
                      acceptances, agreements, understandings, contracts and
                      communications, whether oral or written, between BRAD and
                      Buyer or their respective agents, with respect to or in
                      connection with the subject matter of this Agreement and
                      no agreement or understanding varying the terms and
                      conditions hereof shall be binding on either BRAD or Buyer
                      hereto unless an amendment to this Agreement is issued and
                      duly signed by their respective authorized representatives
                      pursuant to the provisions of Article 7 hereof. In the
                      event of any inconsistencies within the Agreement between
                      this Purchase Agreement and any of the Exhibits, Annexes
                      or Letters of Agreement referred to herein, the provisions
                      of this Purchase Agreement shall prevail except that when
                      there is any inconsistency between this Agreement and any
                      Letter of Agreement with respect to the subject matter
                      covered by the terms contained therein, then such Letter
                      Agreement shall prevail.

            24.2       If any of the provisions of this Agreement are for any
                       reason declared by judgment of a court of competent
                       jurisdiction to be unenforceable or ineffective, those
                       provisions shall be deemed severable from the other
                       provisions of this Agreement and the remainder of this
                       Agreement shall remain in full force and effect.

1.3      Repair, Replacement or Rework
         -----------------------------

         As to each matter covered by this Warranty, BRAD's sole obligation and

         election, correction by the repair, replacement or rework of any
         defective BRAD Part or item of Technical Data having given due
         consideration to any previous repair, replacement or rework BRAD might
         have already undertaken on behalf of Buyer. The repaired, replaced or
         reworked BRAD Part or item of Technical Data which is the subject of
         the Warranty claim shall then be warranted under the same terms and
         conditions for the then unexpired portion of the Warranty Period or

1.4      Claims Information
         ------------------

         1.4.1        BRAD's obligations hereunder are subject to a Warranty

                      administrator and which shall include but not be limited
                      to the following information:

                             apparent to Buyer;

                      d.     the total flight hours (and cycles if applicable)
                             accrued on the BRAD Part at the time the claimed
                             Defect became apparent to Buyer; and

                      e.     a description of the claimed Defect and the
                             circumstances pertaining thereto.

<PAGE>   102


                      Buyer shall not be denied the benefits of the warranty if,
                      in the event Buyer has failed to provide the above
                      information, Buyer corrects its failure within a mutually
                      acceptable period.

1.5      BRAD's Approval
         ---------------

         Within ten (10) working days following receipt of Buyer's Warranty
         claim for a Defect accompanied by Buyer's request for permission to
         correct a Defect, BRAD shall notify Buyer of its decision to the
         request. Approval under this paragraph shall not constitute a
         determination as to the existence of a Defect as described in paragraph
         1 above.

1.6      Timely Corrections
         ------------------

         BRAD shall make the repair, replacement or rework, following receipt of
         the defective BRAD Part, with reasonable care and dispatch. If during
         this corrective action an AOG or Critical requirement is identified,
         BRAD will provide a loan part to the Buyer.

1.7      Labour Reimbursement
         --------------------

         For correction of Defects, BRAD shall establish a reasonable
             estimate for the labour hours required for the repair,
             replacement or rework of the defective BRAD Part. Buyer and
             BRAD shall mutually agree on reasonable estimates. If the
             repair, replacement or rework is performed by Buyer, BRAD
             shall reimburse Buyer for BRAD estimated hours or for Buyer's
             actual labour hours, whichever is less, for the repair,
             replacement or rework of the defective BRAD Part. Such
             reimbursement shall be based [ * ] subject to annual review
             and adjustment of such labour rate as mutually agreed;
             provided, however, that this amount shall not exceed [ * ] of
             the BRAD selling labour rate of [ * ] expressed in [ * ]
             dollars, [ * ] in accordance with the formula attached as
             Exhibit B.

         BRAD, if requested by Buyer, will dispatch a field repair team to
         assist Buyer to evaluate the corrective action or repair required to an
         Aircraft or BRAD Part found to be defective.

1.9      Approval, Audit, Transportation and Waiver
         ------------------------------------------

         Further to BRAD's approval pursuant to Article 1.5 herein, all Warranty
         claims shall be subject to audit and approval by BRAD. BRAD will use
         reasonable efforts to advise in writing the disposition of Buyer's
         Warranty claim within thirty (30) days (subject to the provisions of
         Article 1.10.1) following the receipt of the claim and (if requested)
         return of the defective BRAD Part to BRAD's designated facility. BRAD
         shall notify Buyer of BRAD's disposition of each claim. The
         transportation cost for the return (if necessary) and the replacement
         of the defective BRAD Part shall be borne by BRAD. Buyer agrees to use
         reasonable efforts to ship the defective BRAD Part via COMAT on Buyer
         airline closest destination to BRAD's designated facility.

1.10     Limitations
         -----------

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

                             BRAD that such products or parts were not a cause
                             of the Defect; or

                             that such operation was not a cause of the Defect;
                             or

                      f.     Buyer does not allow BRAD reasonable opportunity to
                             be present during the disassembly and inspection of
                             the BRAD Part claimed to be defective.

1.11     Normal Usage
         ------------

         Normal wear and tear and the need for maintenance and overhaul as
         defined in the initial Maintenance Review Board shall not constitute a
         Defect or failure under this Warranty.

1.12     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.

1.13     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 costs 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 on 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 incurred by BRAD and charged to Buyer shall
         be waived if not yet paid, or reimbursed if paid.

         However, BRAD has made or shall make reasonable efforts to obtain

         as specifically provided under this Article 2, BRAD shall have no

2.3      BRAD's Interface Commitment
         ---------------------------

         In the event of a dispute in the application of a Vendor Part warranty,
         at Buyer's request 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 investigation,
         shall advise Buyer in writing of BRAD's opinion as to the cause of the

                      apply to this SLP:

                      a.     the transportation cost for the return, if
                             practicable, of any failed Covered Component
                             necessary for failure investigation or redesigning
                             studies shall be borne by BRAD. Buyer agrees to use
                             reasonable efforts to ship the Covered Component
                             via COMAT on Buyer airline destination closest to
                             BRAD's designated facility;

                      b.     BRAD's obligations under this SLP are conditional
                             upon the submission of reasonable proof acceptable
                             to BRAD that the failure is covered hereby;

                      c.     Buyer shall report any failure of a Covered
                             Component in writing to BRAD's Warranty
                             administrator within two (2) months after such
                             failure becomes evident, whether or not such
                             failure can reasonably be expected to occur in any
                             other Model CL-600-2B19 aircraft;

                      d.     the provisions of Article 1.10 of the Warranty

                             incorporated by this reference and shall condition
                             BRAD's obligations under this SLP with respect to
                             any Covered Component;

<PAGE>   110


                      e.     BRAD's obligations under this SLP shall 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 BRAD from Buyer of any notice of an
                             occurrence which constitutes, or which at a later
                             date is shown to constitute, a failure in a Covered
                             Component. 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 Covered Component
                             where the failure results from an accident, abuse,
                             misuse, degradation, negligence or wrongful act or
                             omission, unauthorized repair or modification
                             adversely affecting a Covered Component, impact or
                             foreign object damage to any Covered Component.

3.5      Coverage
         --------

         This SLP is neither a warranty, performance guarantee nor an agreement
         to modify the Aircraft to conform to new developments in design and
         manufacturing art. BRAD's obligation is only to provide correction
         instructions to correct a Covered Component or furnish replacement at a
         reduced price as provided in this SLP.

3.6      Assignment
         ----------

         The terms and conditions of this Exhibit J are personal to Buyer and
