without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission ("SEC"). Certain information and note disclosures normally
included in financial statements prepared in accordance with generally accepted

regulations, although the Company believes the disclosures which are made are
adequate to make the information presented not misleading. Further, the

adjustments (which include only normal recurring adjustments) necessary to
present fairly the financial position and results of operations as of and for
the periods indicated.

         These consolidated financial statements should be read in conjunction
with the consolidated financial statements and the notes thereto included in the
Company's Annual Report on Form 10-K for the year ended March 31, 1999, which is

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 1999
                                   (Unaudited)



         Reference is made herein to the Notes to Consolidated Financial
Statements included in the Company's Annual Report on Form 10-K for the year
ended March 31, 1999.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Our accounting policies are as set forth in the Notes to Consolidated
Financial Statements referred to above.

         Certain amounts in prior years' consolidated financial statements have
been reclassified to conform to current period financial statement
presentations.

         For our operations where the functional currency is other than the U.S.
Dollar, balance sheet amounts are translated using the exchange rate in effect
at the balance sheet date. Income statement amounts are translated at the
average exchange rates during the year or period. Translation adjustments
resulting from the changes in exchange rates from year to year are recorded as
accumulated other comprehensive income.

         We account for our investment in a 50% owned joint venture under the
equity method of accounting. The joint venture, Skytanking GmbH, located in
Munich, Germany, provides aviation fueling and aircraft ground services at
Munich International Airport.

         The Company, during its ordinary course of business, pursues
acquisition targets frequently and expends funds in that pursuit. The costs of
the acquisition pursuits are capitalized on the balance sheet until such time as
the acquisition occurs or dissolves. If the acquisition occurs, these costs are
reclassified on the balance sheet to their appropriate category. If however, in
the Company's opinion, the acquisition will not occur, then the capitalized
costs associated with that specific acquisition are written off to the income
statement. As of September 30, 1999, the Company had $0.8 million capitalized on
the balance sheet in pursuit of on-going acquisitions.

         In fiscal 1999, we adopted Statement of Financial Accounting Standards
No. 128, "Earnings Per Share" (SFAS No. 128). SFAS No. 128 replaced the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Basic earnings per share will typically be higher
than primary earnings per share due to the exclusion of any dilutive effects of
options, warrants and convertible securities from the calculation. Diluted
earnings per share is similar to the previously reported fully diluted earnings
per share. The adoption of SFAS No. 128 had no impact on the Company.

         Effective January 1, 1998, we adopted Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" (SFAS No. 130), which
establishes standards for reporting and display of comprehensive income and its
components in a full set of general purpose financial statements. Comprehensive
income (loss) includes net income (loss) and other comprehensive income, which
includes, but is not limited to, unrealized gains for marketable securities and
future contracts, foreign currency translation adjustments and minimum pension
liability adjustments. The accompanying financial statements for the Company
reflect other comprehensive income (loss) consisting of net income (loss) and
foreign currency translation adjustments.

         In fiscal 1999, we adopted Statement of Financial Accounting Standards
No. 132, "Employers' Disclosures about Pensions and Other Postretirement
Benefits - an amendment of FASB Statements No. 87, 88, and 106" (SFAS No. 132).
SFAS No. 132 revises employers' disclosures about pension and other
postretirement benefit plans. It does not change the measurement or




                                       6

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)



recognition of those plans; therefore, the adoption of SFAS No. 132 affected the
Company's disclosure information only.

         In fiscal year 2000, we adopted Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (SFAS No. 133), which is effective for fiscal quarters of fiscal
years beginning after June 15, 1999. This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
adoption of SFAS 133 had no impact on the Company.

2. LONG-TERM DEBT

              On April 2, 1998, we issued $75 million of notes (the "Senior
Increasing Rate Notes"). The proceeds from the Senior Increasing Rate Notes were
used to consummate the acquisition of the Aircraft Service International Group
businesses from Viad Corporation. On August 18, 1998, we issued $80 million of
notes (the "Old Notes"). The proceeds from the Old Notes were used to repay the
Senior Increasing Rate Notes. On February 12, 1999, we exchanged the Old Notes
for substantially identical Series B 11% Senior Notes (the "Notes"). The Notes
mature in August, 2005, and bear interest at 11%, payable semiannually on each
February 15 and August 15, commencing February 15, 1999. The Notes are
redeemable at the option of the Company, at any time on or after August 15,
2003, at a premium of 105.5% in 2003 and at 100% of the principal amount in 2004
and thereafter. In addition, we may redeem at our option up to 33 1/3% of the
original principal amount of the Notes at any time on or prior to August 15,
2001, at a redemption price equal to 111% of the

principal amount being redeemed, with the net proceeds of one or more public
offerings, provided that at least $53.3 million aggregate principal amount of
the Notes remain outstanding after any such redemption and that any such
redemption occurs within 90 days following the closing of such public offering.
Upon the occurrence of a Change in Control (as defined in the Indenture covering
the Notes), each holder of the Notes is entitled to require the Company to
repurchase such Notes at a premium of 101%. The Notes are fully and
unconditionally guaranteed, on an unsecured basis, by the Company's domestic
subsidiaries (see Note 6).

         The Notes contain certain covenants, which among other things limit the
ability of the Company to incur additional indebtedness, issue common and
preferred stock of its subsidiaries, pay dividends, transfer and sell assets and
enter into transactions with affiliates.

         Concurrent with the consummation of the issuance of the Old Notes, we
expensed approximately $213,000 to write off the remaining unamortized deferred
financing costs previously incurred in connection with the Senior Increasing
Rate Notes that were repaid with the net proceeds of the issuance of the Old
Notes. The unamortized expenses related to the deferred financing costs were
accounted for as an extraordinary loss on the early extinguishment of debt.

         On April 2, 1998, we entered into a revolving credit facility with Key
Corporate Capital (the "Senior Credit Facility"). The Senior Credit Facility
allows for borrowings in the aggregate of up to the lesser of $10 million or a
borrowing base, equal to 85% of eligible accounts receivable, as defined. The
revolving loans under the Senior Credit Facility mature on August 31, 2002 or
sooner as provided in the Senior Credit Facility.

         Indebtedness of the Company under the Senior Credit Facility is
guaranteed by each of our domestic subsidiaries and will generally be secured
by: (i) all of the Company's cash equivalents, accounts receivable, contract
rights, general intangibles, instruments and chattel paper relating thereto;
(ii) all of the Company's inventory; (iii) amounts (if any) held in a commercial
deposit account with the lending bank, and (iv) all proceeds from (i) to (iii)
inclusive.

         The Company's borrowings under the Senior Credit Facility bear interest
at a floating rate and may be maintained as Prime Rate Loans or LIBOR loans.
Borrowings made pursuant to the Prime Rate Loans bear interest rates equal to
the prime rate plus the Applicable Margin (as defined in the Senior Credit
Facility) and borrowings made pursuant to the LIBOR Loans bear interest rates
equal to the LIBOR rate plus the Applicable Margin. The Applicable Margin for
Prime Rate Loans was 0% through June 1999 and thereafter will range from 0% to
0.50% based on the Company's Leverage Ratio (as defined in the Senior Credit
Facility). The Applicable Margin for LIBOR Loans was 1.75% through June 1999 and
thereafter will range from 1.25% to 2.25% based on the Company's Leverage Ratio.

         The Senior Credit Facility requires the Company to meet certain
financial tests, including, without limitation, minimum interest coverage and
maximum leverage ratios. The Senior Credit Facility also contains certain
covenants, which among other things, will limit the incurrence of additional
indebtedness, the making of loans or investments, the declaration of dividends,
transactions with affiliates, asset sales, acquisitions, mergers and
consolidations, the incurrence of liens and encumbrances and other matters
customarily restricted in such agreements. There was approximately $5.8 million
outstanding under the Senior Credit Facility as of September 30, 1999 and $3.9
million available under the Senior Credit Facility.

         On May 20, 1999, the Senior Credit Facility was amended to add a
$5 million Term Loan (the "Term Loan"). The Term Loan principal is payable in
quarterly installments of $125,000. The interest is due quarterly in arrears
over its five-year life. The Company's borrowings under the Term

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)




          Loan will bear interest in a manner identical to the Senior Credit
Facility except that the Applicable Margin for Prime Rate Loans will range from
0% to 1.25% based on the Company's Leverage Ratio and the Applicable Margin for
LIBOR Loans will range from 2% to 3% based on the Company's Leverage Ratio. The
Company must meet a minimum EBITDA test. The term loan is secured by all of the
Company's equipment.

         On May 20, 1999, the Company entered into a promissory note agreement
in the amount of $899,372 (subject to adjustment as described in the asset
purchase agreement dated May 20, 1999) with Elsinore, L.P. The promissory note,
in conjunction with the amendment to the Term Loan described above was used to
purchase the assets of Elsinore, L.P. The note, along with interest at a rate
equal to eight percent is payable in full on May 20, 2000.

3. ELSINORE, L.P. ACQUISITION

         On May 20, 1999, Elsinore Acquisition Corporation ("EAC"), a
newly-created, wholly-owned subsidiary of the Company, acquired substantially
all of the assets of Elsinore, L.P., ("Elsinore"), which includes 23 operating
units in 10 states, the U.S. Virgin Islands and Puerto Rico. Elsinore provides a
variety of ground handling, fueling, aircraft cleaning and other aviation
services to major commercial airlines. EAC will primarily continue the same
business as previously conducted by Elsinore. The Company and its sole
shareholder, Ranger Aerospace, are guarantors of EAC's obligations under the
agreement governing the asset purchase.

         The total consideration paid by EAC was approximately $5.9 million
(subject to post-closing adjustments), which consists of $5 million in cash and
a promissory note of approximately $0.9 million. The promissory note has a
maturity of one year from the date of purchase, and is subject to post-closing
adjustments. The Company borrowed the cash portion of the purchase price from
Key Corporate Capital, Inc. ("Key") pursuant to the terms of an amendment to the
Company's existing senior credit facility, which the Company recorded on the
books of EAC.

         The Elsinore acquisition was accounted for as a purchase and
accordingly, the purchase price was allocated to the assets acquired and
liabilities assumed based on appraisals and other estimates of their underlying
fair values. The excess of the purchase price over the fair value of net assets
acquired of approximately $3.7 million is classified as goodwill and is being
amortized over 20 years.

The following is a preliminary summary of the purchase price allocation:

        Net working capital, including cash of $9             $1,131
        Property, plant and equipment                            950
        Other assets                                             130
        Goodwill                                               3,688
                                                              ------
                                                              $5,899
                                                              ======
The purchase price was funded as follows:

        Senior Credit Facility (see Note 2)                   $5,000
        Promissory Note (see Note 2)                             899

The unaudited pro forma results have been prepared for comparison purposes only
and include certain adjustments, such as additional amortization expense due to
the goodwill related to the Elsinore acquisition and additional interest expense
associated with the debt related to the Elsinore acquisition. The unaudited pro

actually would have resulted had the Elsinore acquisition occurred on April 1,
1998, or of future results of operation of the Company.

6. SUPPLEMENTAL GUARANTOR CONDENSED CONSOLIDATING/COMBINING FINANCIAL STATEMENTS

     The Company offered $80 million in aggregate principal amount of Series B
11% Senior Notes due 2005 (the "Notes"). The Notes are fully and unconditionally
guaranteed on a senior unsecured basis, jointly and severally, by the Company's
domestic subsidiaries (the "Guarantors"). The Guarantors include Aircraft
Services International, Inc., Dispatch Services, Inc., Florida Aviation Fueling
Co and Elsinore Acquisition Corporation. The condensed consolidated financial
statements of the Guarantors should be read in connection with the consolidated
financial statements of the Company. Separate financial statements of the
Guarantors are not presented because the Company believes such information is
not material and that the condensed consolidated financial statements presented
are more meaningful in understanding the financial position and results of
operations of the Guarantors. Those supplemental guarantor condensed combining
financial statements that do not contain a column for elimination entries and/or
a column for ASIG, Inc. do so because all amounts that would appear in the
column are zero.

</TABLE>

         EBITDA is defined herein as net income (loss) before interest, income
taxes, depreciation, amortization, extraordinary items and other income/(loss).
Although EBITDA is not a measure of performance calculated in accordance with
generally accepted accounting principles ("GAAP"), the Company has included
information concerning EBITDA because it is commonly used by certain investors
and analysts as a measure of a company's ability to service its debt
obligations. The company's calculation of EBITDA may not be comparable to
similarly titled measures reported by other companies since all companies do not
calculate this non-GAAP measure in the same manner. The Company's EBITDA
calculation is not intended to represent cash used in operating activities,
since it does not include interest and taxes and changes in operating assets and
liabilities, nor is it intended to represent the net increase or decrease in
cash, since it does not include cash provided by (used) in investing and
financing activities.

Summary Three and Six Months Ended September 30, 1999 and 1998

         The Company's business includes aviation fueling services; aircraft
ground services and other aviation services. Aviation fueling services are
comprised primarily of into-plane fueling, maintenance and operation of fuel
storage and delivery systems and the retail sale of fuel products. Generally,
the Company has custody over, but not ownership of, the fuel it manages and
delivers. Aircraft ground services consist primarily of ground handling,
aircraft interior grooming, cargo handling, passenger and traffic services and
Fixed Base Operations (FBOs). The Company acquired the business of Elsinore,
L.P. on May 20, 1999 (See Note 3 to Notes to Consolidated Financial Statements)
and Gatwick Handling on January 12, 1999.

to temporary station closures caused by Hurricane Floyd. Thus, for the quarter
ended September 30, 1999, core business (business excluding the British Airways
grooming contract, the acquisitions of Elsinore, L.P. and Gatwick Handling and
the impact of Hurricane Floyd) revenue increased $4.0 million or 14.4%. Revenues

closures caused by Hurricane Floyd. Thus, for the six months ended September 30,
1999, core business (business excluding the British Airways grooming contract,
the acquisitions of Elsinore, L.P. and Gatwick Handling and the impact of
Hurricane Floyd) revenue increased $7.4 million or 13.5%.

           Operating expenses for the quarter ended September 30, 1999 increased
$3.5 million or 13.9% from $25.1 million to $28.6 million. Included in the

business operating expenses compared to core business revenues equaled 81.0%
versus 81.1% for the comparable quarter in 1998. Operating expenses for the six

for the six months ended September 30, 1999, over the same period last year due
to the addition of Elsinore, L.P. and Gatwick Handling, as well as, the
depreciation of the leasehold improvements before the re-valuation done at March
31, 1999.

         Interest expense decreased $0.5 million for the quarter ended September
30, 1999 as compared to the same period last year due to higher amortization of
deferred financing costs in the prior year. Interest expense decreased $1.4
million for the six months ended September 30, 1999 as compared to the same
period last year due to the higher amortization of deferred financing costs in
the prior year.

Liquidity and Capital Resources

         Net cash used in operating activities was $3.1 million for the six
months ended September 30, 1999, as compared to $3.0 million cash provided by
operating activities for the same period of 1998. The net cash provided by
operating activities decreased primarily due to a $5.3 million increase in
accounts receivable due to the acquisition of Elsinore, L.P. and Gatwick
Handling, new contracts won and a $1.5


                                       22

million increase in prepaid expenses primarily relating to the Epsilon lease.
These funds will be released to us within the current fiscal year.

         Net cash used in investing activities was $11.7 million for the six
months ended September 30, 1999 as compared to $94.4 million for the same period
of 1998. The decrease in cash used was primarily attributable to the acquisition
of the Company for $88.0 million during the six months ended September 30, 1998.
For the six months ended September 30, 1999 net cash used includes the purchase
price of Elsinore, L.P. of approximately $5.9 million.

         Net cash provided by financing activities was $12.2 million for the six
months ended September 30, 1999 as compared to $4.7 million for the six months
ended September 30, 1998. This increase is primarily due to a new term loan of
$5.0 million from Key Bank and an equity contribution of $3.7 million from
Ranger Aerospace.

         Our primary sources of liquidity are from cash flow provided by
operations and borrowings under our Senior Credit Facility. Based upon the
successful implementation of management's business and operating strategy, we
believe that these funds will provide sufficient liquidity and capital resources
to meet current and future financial obligations, including the payment of
principal and interest on the Notes, as well as, to provide funds for our
working capital, capital investments and other needs for the next twelve months.
Our future operating performance and ability to service or refinance the Notes
and to repay, extend or refinance the Senior Credit Facility will be subject to
future economic conditions and to financial, business and other factors, many of
which are beyond our control. There can be no assurance that such sources of
funds will be adequate and that we will not require additional capital from
borrowings or securities offerings to satisfy such requirements. In addition,
there can be no assurance that we will have sufficient available capital
resources to realize our acquisition strategy. Such future acquisitions,
depending on their size and the form of consideration, may require us to seek
additional debt or equity financing.

Year 2000 Issue

         The staff of the Securities and Exchange Commssion has indicated that
each public company should discuss its "Year 2000" issues. The Year 2000 issue
arises because many computer systems were designed to identify a year using only
two digits, instead of four digits, in order to conserve memory and other
resources. For instance, "1999" would be held in the memory of a computer as
"99".

         When the year changes from 1999 to 2000, a two digit system would read
the year as changing from "99" to "00." For a variety of reasons, many computer
systems are not designed to make such a date change or are not designed to
"understand" or react appropriately to such a date change. Therefore, as the
date changes to the year 2000, many computer systems could completely stop
working or could perform in an unpredictable manner.

         The Company has conducted a review of its computer systems to identify
the systems which it anticipated could be affected by the Year 2000 issue, and
the Company believes that all such systems, were already, or are being converted
to be, Year 2000 compliant. Such conversion, where required, did not entail
material expenditures by the Company. Pursuant to the Company's Year 2000
planning, the Company has requested information regarding the computer systems
of its key suppliers, customers, creditors, and financial service organizations
and has been informed that they are substantially Year 2000 compliant. There can
be no assurance, however, that such key organizations are actually year 2000
compliant and that the year 2000 issue will not adversely affect the Company's
financial position or results of operations. The Company believes that its
expenditures in addressing its Year 2000 issues will not have a material adverse
effect on the Company's financial position or results of operations.

CONTINGENCY PLANS

         The Company does not currently have any contingency plans with respect
to Year 2000 issues. If in the future the Company identifies a material problem
with a critical system, the Company will develop





                                       23
<PAGE>   26

an appropriate contingency plan at that time. However, circumstances may occur
for which there are no satisfactory contingency plans, such as airline flight
disruptions, airport air traffic control problems, among others.

Euro Conversion Issue

On January 1, 1999, certain member countries of the European Union established
fixed conversion rates between their existing currencies and the European
Union's common currency ("Euro"). The transition period for the introduction of
the Euro will be between January 1, 1999 and January 1, 2002. The Company is
currently evaluating methods to address the many issues involved with the
introduction of the Euro, including the conversion of information technology
systems, recalculating currency risk, strategies concerning continuity of
contracts, and impacts on the processes for preparing taxation and accounting
records.

Based on its work to date, the Company believes the Euro conversion will not
have a material adverse impact on the Company's consolidated financial
statements.

Impact of Inflation

Although the Company cannot accurately determine the precise effect of inflation
on its operations, it does not believe that inflation has had a material effect
on its revenue or results of operations for the periods presented herein.
However, substantial increases in the Company's costs, particularly labor or
employee benefits costs, would be likely to adversely affect the Company's
revenues and operating results. In addition, because inflation would likely
materially and adversely affect the airline industry as a whole, and the
Company's business depends to a large extent on the economic health of the
airline industry, an increase in inflation would likely have a material adverse
effect on the Company's revenue and operating results.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to interest rate risk in connection with the revolving
loans and the term loan under its Senior Credit Facility, which bear interest at
floating rates. As of September 30, 1999, there was approximately $5.8 million
outstanding under the revolving loans (at an interest rate of 8.25% at such
time) and $4.9 million outstanding under the term loan (at an interest rate of
8.75% at such time). The Company currently believes that the interest rate risk
associated with these loans is not material.

Also, approximately 8.6% of the Company's revenues are generated by its
operations in the United Kingdom and are denominated in British Pounds. The
financial condition and results of operations of the Company's U.K. operations
are reported in British Pounds and then translated into U.S. dollars at the
applicable rate for inclusion in the Company's consolidated financial
statements. As a result, the Company's reported results would be impacted by
changes in the exchange rate between the U.S. dollar and the British Pound. The
Company does not seek to mitigate this translation risk through the use of
derivative financial instruments and currently believes that such risk is not
material.
