1.  BASIS OF PRESENTATION AND NATURE OF BUSINESS

BASIS OF PRESENTATION

Aircraft Service International Group, Inc. (the "Company") was organized in
March 1998 for the purpose of acquiring beneficial ownership and control of all
the outstanding capital stock or other equity interests in Aircraft Service
International, Inc., Dispatch Services, Inc., Florida Aviation Fueling Co.,
Bahamas Airport Service, Ltd., Freeport Flight Services, Ltd., Aircraft Service,
Ltd., ASII Holding GmbH, and ASII Aircraft Service Canada, Ltd. (collectively
the "ASIG business") from Viad Corp ("Viad") and Viad Service Companies, Limited
as of April 1, 1998 pursuant to a share purchase agreement (the "Acquisition").
Prior to the Acquisition by the Company, Viad operated the ASIG business under
the divisional name of Aircraft Services International Group. The Company is
100% owned by Ranger Aerospace Corporation ("Ranger"). Prior to April 1, 1998,
the Company had no operations.

On April 1, 1998, the Company completed the Acquisition for a purchase price of
approximately $95 million in cash plus fees and expenses of approximately $4.1
million. The original purchase price was subject to a purchase price adjustment
in favor of the Company for any shortfall in the net asset value, net working
capital or required cash (as such terms are defined in the purchase agreement)
of the ASIG business from the levels represented at the closing of the
Acquisition. The purchase price was also subject to adjustment in favor of Viad
in an amount equal to the amount of cash in the ASIG business at the closing of
the Acquisition in excess of the required cash. As a result of the purchase
price adjustments, the Company is due a purchase price settlement of $2.125
million from Viad, which is shown in the accompanying consolidated balance sheet
as a receivable.

The 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
$50.8 million is classified as goodwill and is being amortized over 20 years.

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, 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.

4.  NOTES PAYABLE

On April 2, 1998, the Company 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 in the
Senior Credit Facility. 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 the Company's domestic subsidiaries and will generally be secured by:
(i) all of the Company's existing and future accounts receivable, contract
rights, general intangibles, instruments and chattel paper relating thereto;
(ii) all of the Company's currently-owned and after-acquired inventory; (iii)
amounts (if any) held in a commercial deposit account with the lending bank;
(iv) existing and future cash, cash equivalents, instruments and deposit
accounts relating to items (i) to (iii); and (v) all proceeds from (i) to (iv).

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, 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 $7,475 outstanding under the Senior
Credit Facility as of June 30, 1999.

                                   (UNAUDITED)


4.  NOTES PAYABLE -(CONTINUED)

The amounts outstanding under the Senior Credit Facility bear interest at 7.75%.
As of June 30, 1999 there was $2,260 of available credit 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") and to amend certain existing provisions. The proceeds of
the Term Loan were used as part of the purchase price for Elsinore. The Term
Loan is payable in quarterly installments in arrears at varying amounts over its
five-year life. The Company's borrowings under the Term Loan will bear interest
in a manner similar 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. Furthermore, the requirement to meet a
minimum interest coverage test is no longer applicable for either the Term Loan
or Senior Credit Facility as of April 1, 1999. Rather, the Company must meet a
minimum EBITDA test.

Indebtedness of the Company under the Term Loan will generally be secured by:
(i) all of the Company's currently-owned and after-acquired equipment; (ii)
amounts (if any) held in a commercial deposit account with the lending bank;
(iii) existing and future cash, cash equivalents, instruments and deposit
accounts relating to items (i) and (ii); and (iv) all proceeds from (i) to
(iii).

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. The promissory note, in conjunction
with the amendment to the Term Loan described above was used to purchase the
assets of Elsinore. The note, along with interest at a rate equal to eight
percent is payable in full on May 20, 2000.

5.   LONG-TERM DEBT

On April 2, 1998, the Company issued $75 million of notes (the "Senior
Increasing Rate Notes") in a private placement. The proceeds from the Senior
Increasing Rate Notes were used to consummate the Acquisition. On August 18,
1998, the Company issued $80 million of notes (the "Old Notes") in a private
placement. The proceeds from the Old Notes were used to repay all of the Senior
Increasing Rate Notes. On February 12, 1999, the Company exchanged all of the
Old Notes for substantially identical Series B 11% Senior Notes (the "Notes") in
a transaction registered with the SEC. 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, the
Company may redeem at its 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 7).

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.

6. LITIGATION

The Company is engaged in litigation arising in the normal course of business.
Management believes that the outcome of such litigation will not have a material
adverse effect on the Company's financial position or its results of operations.

7.  SUPPLEMENTAL GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS

The Company's Notes are fully and unconditionally guaranteed on a senior
unsecured basis, jointly and severally, by the Company's wholly owned domestic
subsidiaries (the "Guarantors"). The Guarantors include Aircraft Services
International, Inc., Dispatch Services, Inc., Florida Aviation Fueling Co.
Guarantor documents are in the process of being executed for Elsinore
Acquisition Corp. The condensed consolidating 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 consolidating 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 do so because
all amounts that would appear in the column are zero.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

The following discussion of the Company's consolidated results of operations and
financial condition should be read in conjunction with the consolidated
financial statements and the Notes thereto, which appear in Part I, Item 1 of
this Form 10-Q.

FORWARD-LOOKING INFORMATION

This report contains statements that may constitute "forward-looking statements"
as defined in Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended. Such forward-looking
statements are based on management's current plans, beliefs and expectations as
well as on assumptions made by and information currently available to the
Company at the time these forward-looking statements were made. When used in
this report, words such as "anticipate," "believe," estimate," expect,"
"intends" and similar expressions, as they relate to the Company, are intended
to identify forward-looking statements. These forward-looking statements are
subject to various risks and uncertainties that could cause actual results to
differ from those described in the forward-looking statements. Such risks and
uncertainties include, but are not limited to: the substantial leverage of the
Company; restrictions imposed by the Senior Credit Facility and the Indenture;
general economic conditions; effects of aviation fuel availability and price
increases on customers; the credit quality of the Company's receivables;
dependence on significant customers; competition; the nature of the Company's
contracts; the nature and rights of the Company to operate at airports; the
Company's participation in a regulated industry; the Company's relationship with
its unions and ability to retain employees; and its dependence upon key
personnel. This list of risks and uncertainties is not intended to be exhaustive
and should be read in conjunction with other cautionary statements made in this
report, in other reports and registration statements of the Company filed from
time to time with the SEC and in press releases issued by the Company from time
to time.

OVERVIEW

The Company's business includes aviation fueling services (62% of fiscal year
1999 revenues); aircraft ground services (35%) and other aviation services (3%).
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).

An investor group capitalized Ranger Aerospace Corporation with an aggregate
investment of $24.1 million, all of which was contributed as equity to the
Company, by Ranger in return for all of the Company's outstanding common stock
on April 1, 1998. The net proceeds from the equity investment and the Company's
issuance of $75 million of Senior Increasing Rate Notes were used to consummate
the acquisition of the ASIG business from Viad for $95 million (subject to final
adjustments). Concurrent with the acquisition of the ASIG business (the
"Acquisition"), the Company entered into a $10 million senior credit facility
which was subsequently amended in May 1999 and increased to $15 million to
consummate the purchase of the assets of Elsinore.

REVENUES

Into-plane fueling service consists of providing airplanes with specified
amounts of fuel from fuel storage facilities located at or near the airport. The
Company generally records revenue from its into-plane fueling contracts based on
a fee per gallon of fuel delivered. Fuel system maintenance and operation
consists of the maintenance and operation of the fuel storage and delivery
systems at an airport. These systems are typically composed of storage tanks,
pumps, pipes and filter/separators. The Company generally records revenue from
its maintenance and operation contracts based on reimbursement of costs, plus an
additional monthly fee. In addition, the Company sells aviation fuel to private
aircraft at retail prices at locations where it has FBOs.

Ground handling services consist of the provision of ground handling crews and
all necessary ground support equipment to process airline flights through the
full range of on-the-ground services. Aircraft interior grooming consists of the
cleaning of aircraft cabins between flights and cargo handling consists of the
loading,



                                       16
<PAGE>   17

warehousing and documentation of cargo. Passenger and traffic services include
passenger ticketing, check-in and boarding, security clearance, special
assistance and skycap services. FBOs generally include the provision of terminal
services, pilot facilities, maintenance, weather service, flight planning and
hangar space to private, executive and corporate aircraft. For each of these
aircraft ground services, other than FBOs, the Company is generally compensated
by a fixed fee for each aircraft serviced, based on the size of the aircraft.
For FBOs, the Company is generally compensated by a fixed fee for specific
services rendered.

The Company provides its services to its customers pursuant to contractual
agreements and currently has approximately 800 contracts. In fiscal year 1999,
the Company's largest contract accounted for 5.0% of revenue and no other
contract accounted for more than 3.6% of revenue. The majority of the Company's
contracts have an industry standard initial length of one year, although the
Company's larger contracts generally run for initial terms of three to five
years.

COSTS AND EXPENSES

The Company's principal operating expenses are labor costs and direct
supervision at its stations along with related benefits and payroll taxes, cost
of fuel sold, workers' compensation, property and liability insurance, rent
expense, repairs and maintenance expenses and miscellaneous other direct
station-related expenses. Certain of these expenses are relatively fixed,
regardless of the extent of operations at a particular station, including the
cost of the facility, station management and related administrative expenses.

Selling, general and administrative expenses include the costs of marketing the
Company's services, general supervision provided to the stations, and
accounting, finance and personnel related expenses. These costs are generally
comprised of labor costs and related benefits and payroll taxes, legal and other
professional fees and miscellaneous expenses.

RESULTS OF OPERATIONS

The following table summarizes the Company's results of operations as a percent
of revenue for the periods indicated (dollars in millions):

</TABLE>


EBITDA is defined herein as net income (loss) before interest, income taxes,
depreciation, amortization and other income (expense). Although EBITDA is not a
measure of performance calculated in accordance with generally accepted
accounting principles, 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.

THREE MONTHS ENDED JUNE 30, 1999 COMPARED TO THREE MONTHS ENDED JUNE 30, 1998

Revenues increased $2.4 million, or 7.9%, from $30.2 million for the three
months ended June 30, 1998, to $32.6 million for the three months ended June 30,
1999. This increase was attributable to, among other things, the purchase of
substantially all of the assets of Elsinore (by Elsinore Acquisition Corp.) and
all of the stock of Ground Aviation Handling (renamed ASIG U.K.) which generated
$1.4 million and $1.0 million in revenues respectively. Additionally, $2.1
million was attributable to increased business awarded in Philadelphia, Atlanta,
San Francisco, and Orlando. The increase was partially offset by the lost
British Airways grooming contract at Heathrow airport in London which amounted
to $2.9 million in revenues for the three months ended June 30, 1998.

Operating expenses increased $2.1 million, or 8.6%, from $24.3 million for the
three months ended June 30, 1998 to $26.4 million for the three months ended
June 30, 1999. This increase was primarily attributable to increased labor costs
resulting from the additional revenue mentioned above, bonus payments, and
uniform costs associated with branding to the ASIG logo. As a result, operating
expenses as a percentage of revenues increased from 80.5% for the three months
ended June 30, 1998 to 81.0% for the three months ended June 30, 1999.

Selling, general and administrative expenses increased $0.6 million, or 30.0%,
from $2.0 million for the three months ended June 30, 1998, to $2.6 million for
the three months ended June 30, 1999. This increase was principally due to
increased legal fees, audit fees, and payroll and fringe benefits relating to
additional administrative positions needed to support the Company's growth. As a
result, selling, general and administrative expenses as a percentage of revenue
increased from 6.6% for the three months ended June 30, 1998 to 8.0% for the
three months ended June 30, 1999.

Depreciation and amortization expenses increased $0.3 million, or 13.6%, from
$2.2 million for the three months ended June 30, 1998 to $2.5 million for the
three months ended June 30, 1999. The increase was caused primarily by
depreciation of fiscal 1999 capital expenditures and amortization of goodwill
associated with the purchase of the assets of Elsinore. Depreciation and
amortization expenses as a percentage of revenues increased from 7.3% for the
three months ended June 30, 1998 to 7.7% for the three months ended June 30,
1999.

As a result of the above factors, operating income decreased $0.6 million from
$1.7 million for the three months ended June 30, 1998 to $1.1 million for the
three months ended June 30, 1999. Operating income margins decreased from 5.6%
for the three months ended June 30, 1998 to 3.4% for the three months ended June
30, 1999.

Interest and other financial expense decreased $0.9 million from $3.5 million
for the three months ended June 30, 1998 to $2.6 million for the three months
ended June 30, 1999. This decrease is primarily attributable to lower
amortization of deferred financing costs related to the Senior Notes outstanding
at June 30, 1999 compared to amortization of deferred financing costs related to
the Senior Increasing Rate Notes outstanding at June 30, 1998, partially offset
by current year interest charges on the outstanding balances of the Senior
Credit Facility and the borrowings for the Elsinore Acquisition.

The net loss decreased $0.5 million from $1.9 million for the three months ended
June 30, 1998, to $1.4 million for the three months ended June 30, 1999.

The foregoing factors resulted in a decrease in EBITDA of $0.3 million, or 7.7%,
from $3.9 million for the three months ended June 30, 1998 to $3.6 million for
the three months ended June 30, 1999. EBITDA margin decreased from 12.9% to
11.0% for the respective periods.

Net cash provided by (used in) operating activities was $3.1 million for the
three months ended June 30, 1998, as compared to $(2.4) million for the three
months ended June 30, 1999. Net cash provided by operating activities decreased
primarily due to an increase in accounts receivable.



                                       18

Net cash used in investing activities was $91.5 million for the three months
ended June 30, 1998, as compared to $9.6 million for the three months ended June
30, 1999. The 1998 amount reflects the Acquisition of the ASIG business in April
1998. The 1999 amount primarily reflects the acquisition of the assets of
Elsinore in May 1999. In addition to investing in acquisitions, in the normal
course of the Company's business, net cash used in investing activities is also
affected by the Company's capital expenditure needs for maintaining and
upgrading its existing vehicle and equipment fleet, and generally represents a
majority of the Company's capital expenditures. In addition, the Company
frequently makes capital investments necessary to support new contracts won by
the Company.

Net cash provided by financing activities was $94.4 million for the three months
ended June 30, 1998 and $10.4 million for the three months ended June 30, 1999.
The 1998 amount primarily reflects the issuance of common stock of the Company
and borrowings under the Senior Increasing Rate Notes in April 1998, while the
1999 amount primarily represents borrowings against the Senior Credit Facility
and the related term loan used to finance the purchase of the assets of Elsinore
in May 1999.

The Company's primary sources of liquidity are cash flow from operations and
borrowings under its Senior Credit Facility. The Company needed additional funds
to meet its debt service obligation for the August 1999 payment on the 11%
Senior Notes. The required funds were received in the form of additional equity
contributed from the owner of the company. Other than the aforementioned, based
upon the successful implementation of management's business and operating
strategy, the Company believes that its cash flows from operations and
borrowings under its Senior Credit Facility will provide sufficient liquidity
and capital resources to meet current and future financial obligations,
including the future payments of principal and interest on the 11% Senior Notes,
as well as provide funds for the Company's working capital, capital investments
and other needs for the next twelve months. The Company's future operating
performance and ability to service or refinance the 11% Senior Notes and to
repay, extend or refinance its Senior Credit Facility will be subject to future
economic conditions and to financial, business and other factors, many of which
are beyond the Company's control. There can be no assurance that such sources of
funds will be adequate and that the Company will not require additional capital
from borrowings or securities offerings to satisfy such requirements. In
addition, there can be no assurance that the Company will have sufficient
available capital resources to realize its acquisition strategy. Such future
acquisitions, depending on their size and the form of consideration, may require
the Company to seek additional debt or equity financing.

RECENT DEVELOPMENTS

No material events have occurred since the acquisition of substantially all of
the assets of Elsinore, L.P. by Elsinore Acquisition Corporation.

ENVIRONMENTAL MATTERS

The Company is subject to compliance obligations and liabilities imposed
pursuant to federal, state, local and foreign environmental and workplace health
and safety requirements, including CERCLA. In particular, the Company's aviation
fueling services are subject to liabilities and obligations relating to the
above ground and underground storage of, and the release and cleanup of,
petroleum products. Although the Company believes it is in material compliance
with environmental, health and safety requirements, the possibility exists that
noncompliance could occur or be identified in the future, and the penalties or
costs of corrective action associated therewith could have a material adverse
effect on the Company's business, operating results and financial condition. In
addition, requirements are complex, change frequently and have tended to become
more stringent over time, and there can be no assurance that these requirements
will not change in the future in a manner that could materially and adversely
affect the Company.

The Company is currently conducting or funding, or expects to conduct or fund,
environmental investigations, monitoring and cleanups at certain of its
previously or currently operated facilities. Also, from time to time, the
Company receives notices of potential liability for cleanup costs associated
with offsite waste recycling or disposal facilities at which wastes associated
with its operations allegedly have come to be located. In addition, airport
authorities are coming under increasing pressure to clean up previous
contamination at their facilities and are seeking financial contribution from
airport tenants and companies which operate at their airports. Although the
Company has taken steps to mitigate or remove the foregoing liabilities, the
Company could bear


                                       19
<PAGE>   20

direct liability for the foregoing matters and such liability could have a
material adverse effect on the Company's business, operating results and
financial condition.

YEAR 2000 ISSUE

READINESS

The Company has evaluated and believes it has addressed the Year 2000 issue as
it relates to its internal information technology systems. The Company's
internal efforts included the upgrading of critical hardware and software
systems to become Year 2000 compliant. The Company is in the process of
surveying its customers with whom it has material relationships for Year 2000
compliance.

COSTS

The costs of achieving Year 2000 compliance have not been material to date and
additional costs are not expected to be material.

RISKS

Based on its investigation to date, the Company does not believe it will
experience any material adverse effects as a result of the Year 2000 issue.
However, there can be no assurance in this regard, and the Year 2000 issue could
have a material adverse effect on the Company. While the Company has undertaken
its own evaluation and testing of its information technology systems, it is
dependent to some extent on the assurance and guidance provided by suppliers of
hardware, software and programming services as to its Year 2000 readiness.

The Company's Year 2000 evaluation includes an analysis of the possible effects
on, and the state of Year 2000 compliance by, its customers with whom it has
material relationships. However, the Company has limited ability to
independently verify the possible effect of Year 2000 issues on such customers
as this process is limited to such persons' public statements, responses to the
Company's inquiries and information available to the Company from other third
party sources, if any. Therefore, the Company's beliefs about the effects of its
customers' Year 2000 compliance may be inaccurate.

In addition, there can be no assurance that, despite the Company's Year 2000
efforts and its belief that its internal systems are Year 2000 compliant, the
Company will not be materially or adversely affected by the Year 2000 issue. The
most reasonably likely worst case scenario with respect to Year 2000 issues is
that the Company's remediation of its information technology systems proves to
be ineffective and critical systems fail or malfunction as a result of Year 2000
problems and disrupt its operations or the Company's customers (or airports
where its customers operate) Year 2000 remediation efforts are unsuccessful,
which leads to interruptions or problems in their operations, which could
adversely affect the Company. The Company is currently unable to quantify the
effect of such occurrences; however, such events could have a material adverse
effect on the Company.

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 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.




                                       20
<PAGE>   21

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 June 30, 1999, there was approximately $7.5 million
outstanding under the revolving loans (at an interest rate of 7.75% at such
time) and $5 million outstanding under the term loan (at an interest rate of
8.50% 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.
