                          Notes to Financial Statements

Note A - Financial Statements

The financial statements included herein have been prepared, without audit,
pursuant to the rules and regulations of the Securities and Exchange Commission.
These financial statements reflect all adjustments which, in the opinion of
management are necessary to present fairly the results of operations for the
interim periods presented. All adjustments are of a normal recurring nature. We
suggest that these financial statements be read in conjunction with the
financial statements and the notes thereto included in our Annual Report on Form
10-KSB for the year ended June 30, 2002. The results of operations for the three
months ended September 30, 2002 are not necessarily indicative of the results
that may be expected for the year ending June 30, 2003.

Note B - Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

Note C - Cash Equivalents

The Company considers all highly liquid investments with a maturity of three
months or less to be cash equivalents. Cash equivalents exclude restricted cash.

Note D - Maintenance

The cost of rebuilding rotable parts is charged to maintenance as incurred. An
allowance for depreciation is provided for rotable parts to allocate the cost of
these assets, less estimated residual value, over the useful life of the related
aircraft and engines.

Ordinary maintenance and repairs are charged to operations as incurred. The
Company accrues for the cost of overhauls and engine hot-end inspections based
upon contractual hourly rates or the estimated cost of an overhaul.

Note E - Revenue Recognition

Revenue is recognized when transportation has been provided.



                                       6




Note F - Income Taxes

Deferred income taxes are provided for at the statutory rates on the difference
between the financial statement basis and the income tax basis of assets and
liabilities. The deferred tax assets and liabilities represent the future tax
return consequences of those differences, which will either be taxable or
deductible when the assets and liabilities are recovered or settled. Net
deferred tax assets or liabilities are classified in the balance sheet as
current or non-current consistent with the assets and liabilities which give
rise to such deferred income taxes. At September 30, 2002, the Company recorded
a change in the non-current deferred tax asset of $184,754.

Note G - Earnings per Share

outstanding:

Management's Discussion and Analysis of Financial Condition and Results of
Operations
September 30, 2002 and 2001:

Overview

The Company dba Big Sky Airlines (Big Sky) is a regional airline currently
offering scheduled passenger service to 23 communities in six states utilizing a
fleet of fifteen Fairchild Metro III and Metro 23 turboprop aircraft. Big Sky
markets its services under its own two letter code, GQ. The majority of Big Sky
flights also are operated under the airline code of one or more of Big Sky's
code-sharing partners Northwest Airlines, America West Airlines and Alaska
Airlines. Big Sky services to eight communities are provided under contracts
with the U.S. Department of Transportation (DOT) Essential Air Service (EAS)
program. Total operating revenues and passengers carried have grown more than
fivefold from 1997 through 2002.

Big Sky has been a continuous contract holder under the DOT's EAS program since
1980. In addition to the current EAS services, Big Sky provided EAS service to
an additional eight communities in Arkansas, Oklahoma, and Texas from November
1998 through September 2002. Big Sky was significantly underbid by another air
carrier at the expiration of the EAS contract covering these states, and
terminated those services in phases throughout the month of September 2002. Big
Sky's code-sharing relationships with Northwest, America West and Alaska
commenced in June 1999, April 2001, and July 2001, respectively. Each of these
agreements provide for market specific flight connections between Big Sky and
the code-share partner with one stop check-in, baggage transfer and frequent
flyer member mileage for the Big Sky flights. These agreements also provide for
a sharing of the ticket revenue from each passenger making a code-share
connection, on a prorated basis. Approximately 15% of Big Sky's passengers flew
under these agreements during the current quarter.

With the loss of the above mentioned EAS contract, Big Sky has opened up service
to non-subsidized markets that are geographically closer, and provide daily
aircraft flow through the Billings base of operations. Service between Idaho
Falls, ID and Denver commenced September 16, 2002, Casper and Gillette WY
service to Billings commenced on October 21, and service between Olympia WA and
Spokane WA commenced on November 13. This market shift has significantly reduced
reliance on the EAS program and increased the importance of the code-sharing
relationships.

On September 26, 2002 Big Sky announced a merger agreement including tender
offer, subject to contingencies with Mesaba Holdings Inc. (Holdings) and Ranger
Acquisition Corporation (Ranger). The Merger Agreement and Press Release
describing the Merger Agreement was filed with Form 8-K on September 27, 2002.
On October 29, 2002 Holdings and Ranger commenced the Tender Offer for the
acquisition of all of the outstanding shares of Big Sky's 1996 series common
stock for $2.60 per share, the only series of securities that is outstanding.
Also on October 29, Big Sky filed Schedule 14D-9 recommending that the
shareholders of the Company accept the Offer and tender their




                                       9


shares. Under the terms of the agreement, if two-thirds of the outstanding stock
is tendered under the Offer by midnight on November 27, 2002, then Holdings and
Ranger are obligated to complete the acquisition and Big Sky would become a
privately held wholly owned subsidiary of Holdings.

                               ==================    ===================    ================



The reduction in passenger revenues is a direct result of the 5.6% decrease in
passenger traffic from the prior period due to the lingering effects of the
terrorist events of September 11, 2001 ("9/11") and their impact on the economy.
Similarly, the events of 9/11 caused the Federal Aviation Administration to
place severe limitations on the carriage of cargo, resulting in the decreased
revenue from that product. The increase in public service revenues is due to a
program-wide increase in subsidy rates for all EAS contracts provided for under
the Air Transportation Safety and Stabilization Act that was passed by Congress
in response to 9/11. The decrease in other revenues is due to termination of
service to Lea County (Hobbs), New Mexico where the county was providing an
operating subsidy approximating $35,000 per month to offset losses incurred
while attempting to develop that market.

The increase in flying operations expense is attributable increased aircraft
hull insurance premiums that were imposed as a result of 9/11. Workers
Compensation insurance premium increases also contributed to the additional
expense.



                                       10


Maintenance expense was nearly equivalent to the prior period.

The increase in traffic servicing expense is due a significant increase in
passenger liability and war risk insurance premiums, offset in part by the
closing of stations in Mountain Home AR and St. Louis MO. on October 1, 2001.

The decline in marketing expense resulted from the elimination of travel agency
commissions in June 2002, reduced advertising and promotion, and a reduction in
telephone rates that benefits reservations costs.

The increase in general and administrative expense is a result of increased
insurance premiums for director & officers liability, employer practices
liability, workers compensation and general business and auto coverage. In
addition, certain salary increases that were deferred from July 2001 were
instituted in July 2002.

The increase in depreciation is entirely attributable to the write-off of
leasehold improvements made at the Dallas/Fort Worth airport, due to the
termination of service in September 2002 with the loss of the EAS contract in
that region.

Period-ending September 30, 2002        $1,685,448                         ($192,294)


Cash provided by operations for the three months ended September 30, 2002 was
$243,242. Cash used in investing and financing activities was $41,106 and
$202,136 respectively during the period.

Big Sky has established a line of credit through First Interstate Bank and Trust
Co. of Billings for an amount of up to $1,400,000. Big Sky uses the line to
supplement timing differences in cash flows. The maximum amount drawn on the
line of credit during the quarter was $1,400,000 compared to a low of $604,506.
The continuing losses sustained after the events of 9/11 coupled with those over
the previous two years have resulted in the need to secure a sufficient amount
of capital to assure the continued viability of Big Sky. The pending acquisition
by Mesaba Holdings, Inc. and their commitment to Big Sky's future would provide
that required capital. The acquisition also provides the opportunity for
significant cost savings that would have an immediate impact on operating
results and liquidity.

Quantitative and Qualitative Disclosures About Market Risk

Aircraft Fuel

In the past Big Sky has not experienced difficulties with fuel availability and
expects to be able to obtain fuel at prevailing prices in quantities sufficient
to meet its future needs. Big Sky is directly affected by fuel price volatility
and does not currently have a fuel price hedging plan in place. Based upon the
current fleet of aircraft (fifteen Fairchild Metro aircraft) at their current
utilization rates (approximately 2000 hours each, annually), a ten cent per
gallon increase in the price of fuel would add approximately $270,000 in annual
fuel expense.

Interest Rates

Big Sky's earnings are affected by changes in interest rates due to the term of
its revolving line of credit agreement that contains a variable interest rate.
The rate is subject to change based on the Prime Rate published in the Wall
Street Journal. The current interest rate of 6.75% per annum is calculated by
the sum of the Prime Rate (4.75%), plus 2 percentage points. For illustrative
purposes, it is estimated that the current average daily loan balance
outstanding under the line of credit is $1.1 million. Assuming that the same
balance were to exist for an entire year, then a one percentage point increase
in the Prime Rate over that same period would result in additional annual
interest expense of $11,000 ($1,100,000 x .01). Two of Big Sky's long-term debt
agreements also contain variable interest rates that are tied to the Prime Rate.
The combined outstanding principle balance of those loans at September 30, 2002
is approximately $140,000, with the balances declining as payments are made.
Using the same hypothetical increase of one percentage point in the Prime Rate
would result in additional annual interest expense of less than $1,400 due to
the continual decline in the principle balance. All other long term debt
agreements contain fixed interest rates.
