1.  CONSOLIDATED FINANCIAL STATEMENTS - BASIS OF PREPARATION

The consolidated balance sheets at March 29, 1998 and June 29, 1997, the related
consolidated statements of operations for the three and nine months ended March
29, 1998 and March 30, 1997 and the consolidated statements of cash flows for
the nine months ended March 29, 1998 and March 30, 1997 have been prepared by
LaBarge, Inc. (the "Company") without audit. In the opinion of management,
adjustments, all of a normal and recurring nature, necessary to present fairly
the financial position and the results of operations and cash flows for the
aforementioned periods, have been made.

Certain information and footnote disclosures normally included in consolidated
financial statements prepared in conformity with generally accepted accounting
principles have been condensed or omitted. These consolidated financial
statements should be read in conjunction with the audited financial statements
and notes thereto included in the Company's Annual Report on Form 10-K for the
fiscal year ended June 29, 1997.

During the second quarter of fiscal 1998, the Company increased its ownership of
LaBarge Clayco Wireless L.L.C. to fifty-one percent. Beginning with the second
quarter, LaBarge, Inc. is consolidating 100% of the results of this unit into
its financial statements and deducting the minority interest share before
arriving at pretax profits. Sales by and assets of this subsidiary were less
than 3% of total sales and assets for the year.

4.  OTHER ASSETS, NET

During the second quarter, the Company made a $500,000 investment equating to an
ownership position of approximately 10% in Open Cellular Systems, Inc. of St.
Louis. Open Cellular Systems uses shared access communication networks to
provide wireless communication solutions to the general industrial and utility
markets. The capabilities of Open Cellular complement LaBarge's and management
believes this alliance may provide future opportunities for the Company. The
Company accounts for this investment at cost.

During fiscal 1998, the Company invested an additional $2.0 million in
TRANSMEDICA. Payment for this investment included an exchange of approximately
$1.2 million of current accounts receivable and $800,000 cash. The amount of the
receivable was included in other assets, net at June 29, 1997. With this
investment, the Company has an investment in TRANSMEDICA of $2.3 million and
owns approximately 9.5% of its common stock.

</TABLE>

The average interest rate was computed by dividing the sum of daily interest
costs by the sum of the daily borrowings for the respective periods.


6.  INCOME TAXES

Beginning with the current fiscal year, the Company is reporting net earnings on
a fully-taxed basis at a rate of approximately 37% . This is the result of the
revaluation at fiscal 1997 year end of the Company's deferred tax assets,
including its tax loss carryforwards. Thus, net earnings for the quarter ending
March 29, 1998 were $1.3 million or $.08 per share compared with $1.7 million or
$.11 per share for quarter ended March 30, 1997. Assuming a 37% tax rate, 1997
third quarter net earnings would have been $1.1 million or $.07 per share.

At June 29, 1997, the Company had net operating loss carryforwards for federal
income tax purposes of $8.0 million which are available to offset future federal
taxable income through 2004. In addition, the Company has alternative minimum
tax credit carryforwards and

                                      -7-
<PAGE>   8



investment tax credits of approximately $584,000 which are available to reduce
future regular federal income taxes.


7.  CASH FLOWS

Total cash payments for interest for the three and nine months ended March 29,
1998 were $222,000 and $421,000 compared with $133,000 and $609,000 for the
three and nine months ended March 30, 1997.


8.  EARNINGS PER COMMON SHARE

In 1997, the Financial Accounting Standards Board (FASB) issued Statement of
Financial Accounting Standards ("SFAS") No. 128, Earnings per share. SFAS No.
128 replaced the previously reported primary and fully diluted earnings per
share with basic and diluted earnings per share. Unlike primary earnings per
share, basic earnings per share excludes any dilutive effects of options,
warrants, and convertible securities. Diluted earnings per share is very similar
to the previously reported fully diluted earnings per share. All earnings per
share amounts for all periods presented have been restated to conform to the
SFAS No. 128 requirements.

                          OF RESULTS OF OPERATIONS AND
                               FINANCIAL CONDITION


Statements contained herein which are not historical facts are forward-looking
statements that involve risks and uncertainties. Future events and the Company's
actual results could differ materially from those contemplated by those
forward-looking statements. For a summary of important factors which could cause
the Company's actual results to differ materially from those projected in, or
inferred by, the forward-looking statements, see the Company's Form 10-K for the
fiscal year ended June 29, 1997, which is on file with the Securities and
Exchange Commission and available to stockholders from the Company.

LaBarge, Inc. designs, engineers and manufactures sophisticated electronic
assemblies and complex interconnect systems on a custom basis for its customers.
As such, the Company relies heavily on establishing new and maintaining existing
relationships with its customers. The customers are primarily in the commercial
aerospace, defense, geophysical, medical and wireless telecommunications
markets. The Company employs approximately 850 people.

The Company's backlog of firm, unshipped orders at March 29, 1998 was
approximately $65.9 million compared to $62.3 million at March 30, 1997. The
backlog at March 29, 1998 consisted of approximately $43.2 million for various
defense customers, and approximately $22.7 million for commercial electronics
customers. Approximately $19.7 million of the total backlog is not scheduled to
ship within the next 12 months pursuant to the shipment schedules outlined by
our customers.

For the nine months ended March 29, 1998, approximately 53.6% of the Company's
sales were to customers in the defense industry and 46.4% were to customers in
commercial markets including aerospace (9.3%), geophysical (24.0%) and other
(13.1%). Two customers account for in excess of 42.5% of total sales for the
nine months: one in the aerospace/defense market at 27.6% of total sales; one in
the geophysical market at 14.9% of total sales.

The Company has designed and developed the Laser Lancet(R), a small medical
laser, for TRANSMEDICA under a licensing agreement from TRANSMEDICA. TRANSMEDICA
retains responsibility for sales and marketing of the Laser Lancet. In April
1997, TRANSMEDICA received a limited clearance from the U.S. Food and Drug
Administration (FDA) to market and manufacture the device for the purpose of
perforating the skin to collect capillary blood for clinical testing. This
clearance has proven to be too narrow to permit full-scale marketing, thus
further clearance is required from the FDA. It is still too early to predict if
or to what extent the Laser Lancet may contribute to LaBarge's revenues and
earnings.

In the first quarter of fiscal 1998, the Company increased its investment in
TRANSMEDICA by investing $2.0 million through the exchange of approximately $1.2
million of receivables and payment of $800,000 cash. The Company has now
invested $2.3 million and owns

                                      -9-
<PAGE>   10



approximately 9.5% of TRANSMEDICA's common stock. In addition, the Company has
approximately $930,000 in accounts receivable due from TRANSMEDICA. The Company
is currently attempting to reach a satisfactory resolution of the outstanding
receivable with TRANSMEDICA.

On January 2, 1998, the Company purchased the building in which its corporate
headquarters reside in St. Louis, Missouri, through a wholly-owned subsidiary,
LaBarge Properties, Inc. The purchase price was $6.2 million and was financed
through a bank.

RESULTS OF OPERATIONS
NINE MONTHS ENDED MARCH 29, 1998
COMPARED TO NINE MONTHS ENDED MARCH 30, 1997

Net sales for the nine months ended March 29, 1998 were $70.7 million compared
to $71.3 million for the nine months ended March 30, 1997, a decrease of
approximately $564,000 or 1%.

Gross profit for the nine months ended March 29, 1998 was $15.9 million, 22.5%
of sales, compared to $14.5 million, 20.4% of sales, for the nine months ended
March 30, 1997. The increase in gross margins is attributable to lower material
costs as a result of efforts to reduce such costs.

Selling and administrative expenses for the nine months ended March 29, 1998
were $10.0 million, 14.2% of sales, compared to $8.7 million, 12.2% of sales,
for the nine months ended March 30, 1997. The increase in expense is due to
additional personnel and associated travel. The Company's backlog has grown $3.6
million or 5.8% from March 30, 1997 to March 29, 1998.

Earnings from operations were $5.8 million, 8.3% of sales, for the nine months
ended March 29, 1998, compared to $5.8 million, 8.2% of sales, for the nine
months ended March 30, 1997.

Interest expense for the nine months ended March 29, 1998 was $624,000, compared
to $814,000 for the nine months ended March 30, 1997. Redemption of the 12%
Subordinated Notes in February 1997 and reduced interest rates under the current
loan agreement continue to result in lower interest costs.

Equity in loss of joint venture for the nine months ended March 29, 1998 was
$94,000 compared to $145,000 for the nine months ended March 30, 1997 and
represents the Company's share of losses incurred by LaBarge Clayco Wireless
L.L.C. (the "subsidiary"). On September 29, 1997, the Company purchased
controlling interest in the subsidiary by increasing its ownership to fifty-one
percent. Consequently, the Company began consolidating the results of operations
of the subsidiary. The minority interest in loss represents the allocation of
49% of the subsidiary's loss to the minority owners.

Income tax expense for the nine months ended March 29, 1998 and March 30, 1997,
was $1.9 million and $300,000, respectively, an increase of $1.6 million. The
higher tax expense is due to the revaluation at June 29, 1997, of the Company's
deferred tax assets, including its loss

carryforwards, which resulted in the use of a combined tax rate of approximately
37% for the current nine months versus approximately 6% for the nine months
ended March 30, 1997.

The Company has significant net operating loss carryforwards which offset most
of its income tax liabilities. The loss carryforwards are part of the Company's
deferred tax assets included in the balance sheet. As of March 29, 1998,
deferred tax assets were $2.8 million, compared to $4.4 million as of June 29,
1997.

Net earnings for the nine months ended March 29, 1998 were $3.3 million,
compared to $4.6 million for the nine months ended March 30, 1997.

Diluted earnings per common share were $.21 for the nine months ended March 29,
1998 and $.29 for the nine months ended March 30, 1997. If earnings had been
fully taxed for the nine months ended March 30, 1997, they would have been $.20
per share.


RESULTS OF OPERATIONS
THREE MONTHS ENDED MARCH 29, 1998
COMPARED TO THREE MONTHS ENDED MARCH 30, 1997

Net sales for the three months ended March 29, 1998 were $27.0 million compared
to $25.2 million for the three months ended March 30, 1997. This is a 7.0%
increase and is largely attributable to higher shipments in the commercial
aerospace, defense and geophysical markets versus the prior year's quarter.

Gross profit for the three months ended March 29, 1998 was $6.0 million or 22.2%
of sales, compared to $4.8 million or 18.9% of sales, for the three months ended
March 30, 1997. The higher volume of sales in relation to fixed costs and lower
material costs brought about by more favorable pricing from vendors are the
primary reasons for the increased profit dollars.

Selling and administrative expenses were $3.6 million or 13.5% of sales, for the
three months ended March 29, 1998, compared to $2.8 million or 11.1% of sales,
for the three months ended March 30, 1997. The increase in expense is due
primarily to the planned addition of personnel needed to accomplish our internal
goals for revenue growth.

Interest expense for the three months ended March 29, 1998 was $298,000 compared
to $226,000 for the three months ended March 30, 1997. This is due to higher
borrowings to support working capital in the third quarter 1998 versus third
quarter 1997.

The Company has significant net operating loss carryforwards which offset most
of its income tax liability. Income tax expense for the three months ended March
29, 1998 was $734,000 compared to $98,000 for the three months ended March 30,
1997.

Diluted earnings per common share were $.08 for the three months ended March 29,
1998 and $.11 for the three months ended March 30, 1997. If earnings had been
fully taxed for the three months ended March 30, 1997, they would have been $.07
per common share.

FINANCIAL CONDITION & LIQUIDITY

Accounts receivable at March 29, 1998 were $18.2 million compared with $13.4
million at June 29, 1997; an increase of $4.8 million. Receivables included
$930,000 due from TRANSMEDICA which, along with higher volume and slightly
slower payments by several other customers, have caused the increase. Subsequent
to March 29, 1998, significant collections on past due accounts have brought
receivables down.

Inventories at March 29, 1998 and June 29, 1997 were $20.6 million and $14.3
million, respectively. This increase of $6.3 million is attributable to new job
start-ups in support of the higher backlog of orders due to ship in the fourth
quarter for which inventories have been received. To finance these operating
activities, the Company borrowed additional funds totaling $2.0 million during
the third quarter of fiscal 1998.

Also during the nine months ended March 29, 1998, the Company purchased $7.6
million in property, plant and equipment. This includes $6.2 million the Company
used to purchase its corporate headquarters building in St. Louis, Missouri.

During the first nine months of the current fiscal year, the Company invested an
additional $2.0 million in TransMedica International, Inc. ("TRANSMEDICA"),
formerly Venisect, Inc. Payment for this investment included an exchange of
approximately $1.2 million of current accounts receivable and $800,000 cash. The
amount of the receivable was included in other assets, net on June 29, 1997.
With this investment, the Company has invested $2.3 million and owns
approximately 9.5% of TRANSMEDICA's common stock. In addition, accounts
receivable include approximately $930,000 due from TRANSMEDICA.

During the fiscal year 1998, the Company made a $500,000 investment equating to
an ownership position of approximately 10% in Open Cellular Systems, Inc. of St.
Louis. Open Cellular Systems uses shared access communication networks to
provide wireless communication solutions to the general industrial and utility
markets. The capabilities of Open Cellular complement LaBarge's and management
believes this alliance may provide future opportunities for the Company. The
Company accounts for this investment at cost.

For the nine months ended March 29, 1998, the Company made repayments of
long-term debt of $796,000.

The Company used approximately $961,000 of its available cash and borrowed an
additional $9.1 million under revolving credit and $6.2 million for the purchase
of its corporate headquarters during the nine months.
