                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 2000
                                   (Unaudited)


NOTE 1 - BASIS OF PRESENTATION:

        The accompanying unaudited financial statements reflect all adjustments
(consisting of normal, recurring accruals only) which are necessary to fairly
present the results for the interim periods. Such financial statements have been
prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X and therefore do not include all the information or footnotes
necessary for a complete presentation. They should be read in conjunction with
the Company's Annual Report on Form 10-K for the year ended June 30, 1999 and
the notes thereto. The results of operations for the nine months ended March 31,
2000 are not necessarily indicative of results for the full year.

NOTE 2 - INCOME TAXES:

        Income taxes have been computed based on the estimated annual effective
income tax rate for the respective years.

NOTE 3 - PROVISION FOR BAD DEBTS:

        Charge to bad debt expense in the three months ended March 31, 2000 was
$3,634,000 and included the write off of $2,700,000 of accounts receivable from
Tower Air Inc., who filed chapter 11 Bankruptcy on February 29, 2000. The
additional provision of $934,000 is based on significantly higher fuel prices
during the current fiscal year which has increased the Company's risk of loss
from certain airline accounts. Bad debt provision in future periods may continue
to reflect higher risk of loss based on high fuel prices and potential
bankruptcies and will depend upon actual experience. On May 1, 2000 Kitty Hawk,
Inc. and related companies, fuel customers of the Company, filed for bankruptcy
under Chapter 11. The potential write off of this receivable has been considered
in evaluating the March 31, 2000 accounts receivable allowance.

NOTE 4 - STOCKHOLDINGS' EQUITY:

        During the nine month period ended March 31, 2000, the Company
repurchased 234,375 shares of its common stock at a cost of approximately
$1,856,000, or an average price of $7.92 per share, which was charged to: Common
Stock $2,000; Additional Paid In Capital $705,000; and Retained Earnings
$1,149,000.

NOTE 5- EARNINGS PER SHARE:

        Basic income per common share is computed by dividing net income by the
weighted average number of common shares outstanding during the period. Diluted
income per share is computed by dividing net income by the weighted average
number of common shares and common stock equivalents. Common stock equivalents
include stock options, warrants and shares resulting from the assumed conversion
of subordinated debentures, when dilutive. For the three months ended March 31,
2000, weighted average common and common equivalent shares exclude shares
resulting from the assumed exercise of stock options and assumed conversion of
debentures since the impact was anti-dilutive.

NOTE 6 - COMPREHENSIVE INCOME:

        In June of 1997, the Financial Accounting Standards Board issued
statement of Financial Accounting Standard No. 130 "Reporting Comprehensive
Income." This statement, which the Company adopted in fiscal 1999, establishes
standards for reporting and displaying comprehensive income and its components
in a full set of financial statements. For the periods presented, adjustments to
derive comprehensive income were insignificant .


NOTE 7- LITIGATION:

        In connection with the Chapter 7 bankruptcy filing for Western Pacific
Airlines, Inc. ("WPAI"), the Company received a letter dated August 25, 1999,
from the bankruptcy trustee's attorneys making a formal demand for recovery of
alleged preference payments of approximately $11.4 million. This amount
represents cash received for payment of fuel and sales during the 90 days prior
to WPAI's initial bankruptcy filing. The Company believes this claim is without
merit and the entire amount is defensible based on the transaction 1) having
been a substantially contemporaneous exchange for value, 2) being made in the
ordinary course of business, and 3) involving an exchange for new value.
Accordingly, the Company believes it will ultimately prevail and that no
provision is required.

        In October, 1999, Mr. Rene Perez, formerly the president of RPA,
notified the Company of certain alleged violations of his employment contract
dated February 28, 1998 between the Company, RPA and Mr. Perez asserting among
other things constructive termination. The Company subsequently filed a suit
seeking declaratory relief regarding the employment contract in the United
States District Court for Northern California ( San Francisco) in November 1999.
The Company subsequently amended, on November 30, 1999, that suit as a result of
its investigation seeking damages against Mr. Perez. This case has been
transferred to the United States District court for the Southern District of New
York (New York City) in March 27, 2000. Mr. Perez filed a lawsuit, which was
filed in November 1999 and served in December 1999, in the Circuit Court of the
11th Judicial Circuit in Dade County, Florida seeking damages in excess of the
jurisdictional limit. At this time, the Company believes that no provision is
required.


NOTE 8- SUBSEQUENT EVENT:

        On April 21, 2000, the Company acquired certain assets of an FBO located
in Fort Wayne, Indiana (FWAS) for a cash consideration of $3,900,000. The
Company borrowed from its acquisition line to fund the purchase. The purchase
price was allocated primarily to Property, Equipment and Leaseholds and a
portion to inventory.

NOTE 9 - SENIOR SUBORDINATED NOTE / EXTRAORDINARY ITEM:

        On September 10, 1999, the Company issued, in a private placement,
$24,000,000 Senior Subordinated 12% Notes ("the Notes") due 2006 with detachable
warrants to acquire 503,126 shares of the Company's common stock exercisable at
$6.50 per share for seven years. Proceeds of the Notes were used to redeem the
Company's 7 3/4% convertible subordinated debentures due February 1, 2006 at
104% of the principal amount plus accrued interest and pay expenses of the
transaction as follows:

</TABLE>


        The $1,750,000 of fees incurred are being amortized over the term of the
Notes.

        As a result of this transaction the Company recorded an extraordinary
charge of $979,000 net of a $625,000 tax benefit in the first quarter of fiscal
2000. The extraordinary charge includes the redemption premium of $780,000 plus
write off of related capitalized fees of $824,000.


NOTE 10 - ACQUISITIONS:

        On October 22, 1999, the Company acquired certain assets of Air Tulsa,
Inc., an FBO located in Tulsa, Oklahoma. Assets acquired included refueling
equipment and tank farms utilized in the FBO business, customer contracts,
inventory, prepaid expenses and a sublease. Total consideration was $2.4 million
in cash which the Company funded under its acquisition line. The agreement
includes a second closing to occur within eighteen months to include the
purchase of hangars, buildings and the leasehold for an additional cash
consideration of $3.8 million. The Company's Senior lenders have agreed to fund
the amount under the acquisition line.

On October 5, 1999, the Company acquired certain FBO assets of Charleston
Equities, Inc. for $700,000 cash. The purchase consolidated the leasehold at
Charleston International Airport and includes the leasehold at John's Island
Executive Airport.

THREE MONTHS ENDED MARCH 31, 2000 COMPARED TO MARCH 31, 1999.

Revenue increased by 67.7% to $89.9 million in the current period from $53.6
million a year ago primarily due to an increase in the price of fuel and
partially due to an increase in the volume of fuel sold. Gross margin decreased
1.3% to $7.3 million in the current period from $7.4 million a year ago.

Revenues from fuel sales and services represented 63.1% of total revenues in the
current period compared to 50.2% of total revenues a year ago. Revenues from
fuel sales and services increased 110.0% to $56.8 million from $26.9 million
last year. The increase in revenues from fuel sales and services was due to an
increase of 16.3% in the volume of fuel sold and an increase of 84.6% in the
price of fuel . Gross margin from fuel sales and services decreased by 38.4% to
$1.3 million in the current period from $2.1 million last year partly due to
lower margins from fuel sales caused by rising prices and partly due to a loss
of $427,000 from RPA in the current period compared with gross margin of $3,000
a year ago. Revenues and gross margin from fuel sales and services include the
activities of Mercury's contract fueling business as well as revenues from RPA,
its airline information software company. Revenue from RPA was $1,012,000 in the
current period compared with $982,000 a year ago. In January 2000, the Company
appointed a new Chief Executive Officer of RPA.

Revenues from FBOs increased by 46.4% in the current period to $19.6 million
from $13.4 million a year ago due to the addition of Tulsa, Charleston and
John's Island locations and higher fuel prices in the period. Gross margin
decreased 9.4% in the current period to $2.8 million from $3.1 million last
year. The decrease was attributable to an increase in the price of fuel, some of
which was not passed on to customers, resulting in lower per gallon fuel
margins.

Revenues from cargo operations in the current period increased 8.3% to $7.6
million from $7.1 million a year ago. This increase was due to an increase in
space brokerage and cargo handling revenues at LAX. Gross margin from cargo
operations in the current period increased 117.7% to $2.1 million from $1.0
million in the year ago period primarily due to increased space brokerage,
higher cargo handling revenues and elimination of losses at the Miami cargo
location, which was sold in fiscal 1999.

Revenues from government contract services decreased 6.0% in the current period
to $5.9 million from $6.3 million in the year ago period. The decrease in
revenues from government contract services was due primarily to a reduction in
the number of Weather Data contracts. Gross margin from government contract
services decreased approximately 9.8% in the current period to $1.1 million from
$1.2 million a year ago due to lower revenue.

Selling, general and administrative expenses in the current period decreased
7.8% to $1.7 million from $1.9 million in last year's third quarter due
primarily to lower compensation expense.

Provision for bad debts increased by $3,182,000 in the current period to
$3,634,000 from $452,000 in the year ago period due to a $2.7 million write off
of Tower Air Inc's receivable, higher sales in the current period and greater
exposure due to significantly higher fuel prices during the current fiscal year
which has created a greater risk of loss due to potential bad debts related to
certain airline accounts. Future periods may continue to be impacted by higher
reserve requirements related to potential bankruptcies. On May 1, 2000 Kitty
Hawk, Inc. and its related companies, fuel customers of the Company, filed for
bankruptcy under Chapter 11. The potential write off of this receivable has been
considered in evaluating the March 31, 2000 accounts receivable allowance.

Depreciation and amortization expense increased 12.5% in the current period to
$2.4 million from $ 2.1 million a year ago primarily due to the acquisition of
the Tulsa FBO in October 1999 and various capital expenditures.

Interest expense (net) increased 54.2% in the current period to $1.6 million
from $1.1 million a year ago due to higher interest rates and higher average
outstanding borrowings.

Income tax (benefit) expense approximated 39.0% of pre-tax (loss) income in each
period reflecting the expected effective annual income tax rate.


                                       11
<PAGE>   12

In last year's three month period, extraordinary item of $68,000 consists of a
charge of $111,000 related to the cost of repurchasing convertible subordinated
debentures in excess of par value and related bond issuance costs, net of a tax
benefit of $43,000.


NINE MONTHS ENDED MARCH 31, 2000 COMPARED TO MARCH 31, 1999.

Revenues increased 52.3% to $248.1 million in the current period from $162.9
million a year ago primarily due to an increase in the price of fuel and volume
of fuel sold. Gross margin increased 9.7% to $ 25.2 million in the current
period from $22.9 million a year ago due to an increase in gross margin from
cargo operations, which was partially offset by lower gross margins from fuel
sales and services and FBO's.

Revenues from fuel sales and services represented 61.2% of total revenues in the
current period compared to 51.6% of total revenues a year ago. Revenues from
fuel sales and services increased 80.7% to $151.8 million from $84.0 million
last year. The increase in revenues from fuel sales and services was due to an
increase of 50% in the price of fuel and an increase of 25.1% in the volume of
fuel sold. Gross margin from fuel sales and services decreased 25.6% in the
current period to $4.8 million from $6.4 million a year ago. The decrease in
gross margin from fuel sales and services was due to a loss from RPA of $1.3
million in the current period compared to gross margin of $0.6 million last year
caused by lower revenues in the current period. Revenue from RPA was $3.0
million in the current nine month period compared to $4.7 million last year.

Revenues from FBOs increased 31.2% in the current period to $52.5 million from
$40.0 million a year ago due to higher fuel prices and the addition of Jackson
and Charleston in fiscal 1999 and Tulsa in October 1999. Gross margin decreased
9.9% to $8.3 million from $9.2 million in the year ago period due primarily to
an increase in the price of fuel, some of which was not passed on to customers,
resulting in lower per gallon margins.

Revenues from cargo operations in the current period increased 22.0% to $25.0
million from $20.5 million a year ago. The increase was primarily due to an
increase in space brokerage and cargo handling revenues at LAX. Gross margin
from cargo operations in the current period increased 134.3% to $8.4 million
from $3.6 million in the year ago period primarily due to increased space
brokerage, higher cargo handling revenues and elimination of losses in its Miami
cargo handling operation which was sold in fiscal 1999.

Revenues from government contract services in the current period increased 2.2%
to $18.8 million from $18.4 million in the year ago period. The increase in
revenues from government contract services in the current period compared to
last year was primarily due to higher contract revenue from Yokota offset
partially by lower revenue from a lower number of Weather Data contracts. Gross
margin from government contract services in the current period decreased 1.1% to
$3.7 million from $3.8 million last year due to a different contract mix.

Selling, general and administrative expenses in the current period increased
3.3% to $5.4 million from $5.2 million in the year ago period. The increase was
primarily due to higher professional fees.

Provision for bad debts increased by $3,208,000 in the current period to
$4,562,000 from $1,354,000 in the year ago period due to a $2.7 million write
off of Tower Air Inc.'s receivable and a bad debt provision of $1,862,000 due to
significantly higher fuel prices during the current fiscal year which has
created a greater risk of loss due to potential bad debts related to certain
airline accounts. Future periods may continue to be impacted by higher reserve
requirements related to potential bankruptcies. On May 1, 2000 Kitty Hawk, Inc.
and its related companies, fuel customers of the Company, filed for bankruptcy
under Chapter 11. The potential write off of this receivable has been considered
in evaluating the March 31, 2000 accounts receivable allowance.


                                       12
<PAGE>   13


Depreciation and amortization expense in the current period increased 23.0% to
$7.2 million from $5.8 million a year ago. The increase in the current period is
primarily related to the Burbank FBO expansion during fiscal 1999, acquisitions
of Jackson and Charleston FBO's in fiscal 1999, acquisition of Tulsa FBO in
October 1999 and various capital expenditures.

Interest expense (net) increased 45.6% in the current nine months to $4.3
million from $3.0 million a year ago due to higher interest rates and higher
average outstanding borrowings.

Income tax expense approximated 39.0% of pretax income in both periods
reflecting the expected effective annual tax rate.

Extraordinary item of $979,000 in the current nine months consisted of charges
associated with the redemption of the Company's 7 3/4% convertible subordinated
debentures in September 1999. The charge includes a $780,000 redemption premium
plus write off of capitalized fees of $824,000, less a tax benefit of $625,000.

In last years nine month period, extraordinary item of $255,000 consists of a
charge of $418,000 related to the cost of repurchasing convertible subordinated
debentures in excess of par value and related bond issuance costs, net of a tax
benefit of $163,000.

LIQUIDITY AND CAPITAL RESOURCES:

Mercury has historically financed its operations primarily through operating
cash flow, bank debt and various public and private placements of bonds and
subordinated debt. Mercury's cash balance at March 31, 2000 was $1,909,000.

Net cash provided by operating activities was $10,773,000 during the nine month
period ended March 31, 2000. During this period, the primary sources of net cash
provided by operating activities were net income and depreciation and
amortization of $8,457,000, an increase in accounts payable of $9,300,000 and
bad debt expense of $4,562,000. The primary uses of cash from operating
activities was an increase in accounts receivable of $8,491,000. Accounts
receivable at March 31, 2000 increased to $54,063,000 from $50,134,000 at June
30, 1999 due to significantly higher sales in the current nine month period.
Days sales outstanding were approximately 57 at March 31, 2000 versus
approximately 74 at June 30, 1999.

Net cash used in investing activities was $11,161,000 during the current nine
month period. The primary uses of cash from investing activities included
additions to property, equipment and leaseholds of $7,080,000, acquisition of
the Tulsa FBO and assets of the Charleston FBO for $3,100,000 and addition to
other assets of $1,910,000.

Net cash used in financing activities was $2,500,000 during the current nine
month period. The primary uses of cash from financing activities in the current
nine month period was the early extinguishment of the Convertible Subordinated
Debentures of $19,534,000, reduction of long term debt of $10,428,000 and
repurchase of common stock of $1,856,000. The primary sources of cash from
financing activities was proceeds from the Notes of $24,000,000 and proceeds
from the acquisition line of $5,264,000.

The Company's senior secured bank credit facility consists of a $40,000,000
revolver, a term loan with an outstanding balance of $21,000,000 at March 31,
2000 and a $15,000,000 acquisition facility with an outstanding balance of
$5,264,000 at March 31, 2000. At March 31, 2000, there were no borrowings
outstanding under the revolver, however, the line was used to secure $19.0
million in letters of credit. Principal installments are due quarterly on the
term loan over a five year period maturing in March 2004. Balances owed under
the revolver and acquisition facility are due in March 2004. As a result of the
net loss during the current quarter, the Company obtained a waiver from its
lender to cure the violation of its minimum profitability covenant.


                                       13
<PAGE>   14

On September 10, 1999, the Company redeemed $19,509,000 principal balance of
Convertible Subordinated Debentures plus a redemption premium of 4% totalling
$780,000. Financing of the redemption was accomplished by issuing the
$24,000,000 Notes. The Note pays interest quarterly at the per annum rate of
12%. In connection with the issuance of the Note, the Company issued warrants to
purchase 503,126 shares of common stock exerciseable at $6.50 per share.

Absent a major prolonged surge in oil prices or a capital intensive acquisition,
the Company believes its operating cash flows, revolver, vendor credit and cash
balance will provide it with sufficient liquidity during the next twelve months.
In the event that fuel prices increase significantly for an extended period of
time, the Company's liquidity could be adversely affected unless the Company is
able to increase vendor credit or increase lending limits under its revolving
credit facility. The Company believes, however, its revolver and vendor credit
should provide it with sufficient liquidity in the event of a major temporary
surge in oil prices. From June 1999 to March 31, 2000, fuel prices rose
approximately 61%. Significantly higher fuel prices for an extended period of
time have a negative impact on the aviation industry as it increases the
airlines operating expenses. Smaller, less well capitalized airlines may be more
seriously impacted. The current three month period includes a bad debt expense
of $3.6 million, including $2.7 million resulting from the bankruptcy of Tower
Air, Inc., and a bad debt provision of $900,000, due to higher fuel prices
affecting the aviation industry. The bad debt provision in the third quarter of
fiscal 1999 was $452,000. The increase in the general bad debt reserve resulted
from significantly higher fuel prices during the current fiscal year which have
created a greater risk of loss due to potential bad debts related to certain
airline accounts. Future periods may continue to be impacted by higher reserve
requirements related to potential bankruptcies. On May 1, 2000 Kitty Hawk, Inc.
and related companies, fuel customers of the Company, filed for bankruptcy under
Chapter 11. The potential write off of this receivable has been considered in
evaluating the March 31, 2000 accounts receivable allowance. The Company has a
note receivable of approximately $824,000 from a former fuel customer, Saeta, an
Ecuadorian Airline. Due to political and financial crisis in Ecuador, Saeta has
defaulted on its monthly payment obligation of approximately $48,000 since
January 2000, with the exception of one $10,000 payment received in February
2000. The Company has initiated legal action and has obtained a default
judgement against individual guarantors in the U.S. and is proceeding against
Saeta in Ecuador. While no assurance can be given, the Company believes some
portion of the note will ultimately be collected. Bad debt reserves will include
a continuing assessment of the collectability of the Saeta note.

The Company has the following significant contracts or commitments for the
purchase of equipment or installation of facilities. On October 22, 1999, the
Company acquired certain assets of an FBO in Tulsa, Oklahoma for $2.4 million
cash funded from its acquisition line. In a second step to this transaction, the
Company will acquire the leasehold and buildings for $3.8 million within
eighteen months of the first closing. The Company expects to fund this from its
acquisition line. The Company began construction of a 30,000 square foot hangar
at its Bedford Massachusetts FBO in this fiscal period at an estimated cost of
$3.8 million. Approximately $1.9 million has been spent to date and is being
funded under the Company's acquisition line.
