wholly-owned subsidiary representing the entirety of the Plastic Products
business segment. The Company expects that the disposition through sale of
ESP will be completed by the end of fiscal 2002. In conjunction with this
plan, the Company recorded an estimated loss on disposal of discontinued
operations of $3.1 million in the quarter ended April 30, 2002 to reduce the
carrying value of ESP's net assets to their estimated fair value less
estimated selling costs. Accordingly, the Company has reported the results
of operations of ESP as discontinued operations for the three and six months
ended April 30, 2002 and 2001 in the Condensed Consolidated Statements of
Income. All assets and liabilities associated with ESP have been
reclassified as assets and liabilities of discontinued operations on the
April 30, 2002 and October 31, 2001 Condensed Consolidated Balance Sheets.

NOTE F - GOODWILL AND INTANGIBLE ASSETS

         In June 2001, the Financial Accounting Standards Board (FASB)
issued Statements of Financial Accounting Standards No. 141 (SFAS 141),
"Business Combinations," and No. 142 (SFAS 142), "Goodwill and Other
Intangible Assets." Under SFAS 142, goodwill and other intangible assets
deemed to have indefinite lives will no longer be amortized but will be
subject to periodic impairment tests. All other intangible assets will be
amortized over their useful lives. In addition, SFAS 141 eliminates the
pooling-of-interests method of accounting for business combinations.

         The Company adopted SFAS 141 and SFAS 142 as of November 1, 2001.
The Company has identified its reporting units to be its operating
subsidiaries with the exception of Systems & Electronics Inc., which
comprises two reporting units: the Heavy Military Support Equipment and the
Electronics and Automation Systems operating segments of the Company. The
carrying value of each reporting unit as of November 1, 2001 was determined
by assigning assets and liabilities, including existing goodwill and
intangible assets, to the reporting units. Upon adoption of SFAS 142,
amortization of goodwill ceased. The Company has performed a transitional
goodwill impairment assessment which resulted in no impairment of goodwill.
An annual impairment test will be performed in the fourth quarter of each
fiscal year.

         The following pro forma information reconciles reported net income
from continuing operations for the three and six months ended April 30, 2001
to adjusted net income from continuing operations, which reflects the
adoption of SFAS 142:

NOTE G - DERIVATIVES AND HEDGING ACTIVITY

         During the six months ended April 30, 2002, the Company's
derivative contracts consisted only of interest rate swaps used by the
Company to convert a portion of its variable rate long-term debt to fixed
rates. At April 30, 2002, the Company recorded a liability of $895 related
to the fair value of those interest rate swap agreements, which are
designated as and considered highly effective cash flow hedges of the
Company's forecasted variable rate interest payments. The entire
corresponding loss, net of income tax, is recorded in shareholders' equity
as accumulated other comprehensive loss.

NOTE H - SEGMENT INFORMATION

         The Company operates in three segments: Light Military Support
Equipment, Heavy Military Support Equipment, and Electronics and Automation
Systems. Inter-segment revenues for the three and six months ended April 30,
2002 and 2001, respectively, were not significant. Total assets by segment
as disclosed in the Company's annual report for the year ended October 31,
2001 have not changed materially since that date. Goodwill by segment as of
both October 31, 2001 and April 30, 2002 totaled $21,708 for Light Military
Support Equipment, $25,650 for Heavy Military Support Equipment and $24,069
for Electronics and Automation Systems. In addition, there have been no
changes in either the basis of segmentation or the measurement of segment
income since October 31, 2001. Information by segment is as follows:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CRITICAL ACCOUNTING POLICIES

         Revenues on long-term contracts performed within the Company's
Light Military Support Equipment, Heavy Military Support Equipment and
Electronics and Automation Systems segments, substantially all of which are
with the U.S. Government, are recognized under the percentage of completion
method and include a proportion of the earnings that are expected to be
realized on the contract in the ratio that production measures, primarily
labor, incurred bear to the estimated production measures for the contract.
Earnings expectations are based upon estimates of contract values and costs
at completion. Contracts in process are reviewed on a periodic basis.
Adjustments to revenues and earnings are made in the current accounting
period based upon revisions in contract values and estimated costs at
completion. Provisions for estimated losses on contracts are recorded when
identified.

         During the quarter ended April 30, 2002, the Company formally
adopted a plan to dispose of Engineered Specialty Plastics, Inc. (ESP), a
wholly-owned subsidiary representing the entirety of the Plastic Products
business segment. In conjunction with this plan, the Company recorded an
estimated loss on disposal totaling $3.1 million, or $.29 per diluted common
share, in the quarter ended April 30, 2002 to reduce the carrying value of
ESP's net assets to their estimated fair value less estimated selling costs.
Accordingly, the Company has reported the results of operations of ESP as
discontinued operations for the three and six months ended April 30, 2002
and 2001 in the Condensed Consolidated Statements of Income. Additionally,
all depreciation on the property, plant and equipment of ESP was suspended
as of April 30, 2002.

         The following analysis should be read in this context.

RESULTS OF OPERATIONS

         Consolidated net revenues from continuing operations decreased $2.8
million, or 2.9%, to $91.8 million in the second quarter of 2002 compared to
$94.6 million in the second quarter of 2001. The decrease was primarily the
result of lower net revenues in the Light Military Support Equipment segment
due to lower production levels on several programs throughout the quarter.
Gross profit from continuing operations for the three months ended April 30,
2002 increased $3.1 million, or 16.5%, to $21.8 million (23.7% of
consolidated net revenues) from $18.7 million (19.8% of consolidated net
revenues) in the comparable 2001 period. The increase in gross profit was
primarily a result of improved operating performance in the Heavy Military
Support Equipment segment. Selling, general and administrative expense from
continuing operations increased $0.6 million, or 5.7%, in the second quarter
of 2002 to $10.3 million (11.2% of consolidated net revenues) from $9.7
million (10.3% of consolidated net revenues) in the second quarter of 2001.
As a result of the above, operating income from continuing operations
increased $2.5 million, or


                                     11

<PAGE>
<PAGE>

28.2%, in the quarter ended April 30, 2002 to $11.4 million from $8.9
million in the second quarter of 2001.

         Consolidated net revenues from continuing operations increased $2.4
million, or 1.3%, to $183.1 million in the six months ended April 30, 2002
compared to $180.7 million in the first half of 2001. Marginal increases in
the Light Military Support Equipment and Heavy Military Support Equipment
segments were slightly offset by lower revenues in the Electronics and
Automation Systems segment. Gross profit from continuing operations for the
six months ended April 30, 2002 increased $5.6 million, or 15.6%, to $41.7
million (22.8% of consolidated net revenues) from $36.1 million (20.0% of
consolidated net revenues) in the comparable 2001 period. Selling, general
and administrative expense from continuing operations increased $0.9
million, or 4.8%, in the first half of 2002 to $19.7 million (10.8% of
consolidated net revenues) from $18.8 million (10.4% of consolidated net
revenues) in the prior year. As a result of the above, income from
continuing operations increased $4.7 million, or 27.3%, in the six months
ended April 30, 2002 to $22.0 million from $17.3 million in the first half
of 2001.

         LIGHT MILITARY SUPPORT EQUIPMENT. Net revenues for the Light
Military Support Equipment segment decreased by $2.3 million, or 5.8%, to
$37.4 million in the second quarter of 2002 from $39.7 million in the second
quarter of 2001 due to lower production levels on several programs
throughout the period. However, in the six months ended April 30, 2002, net
revenues for the segment increased by $1.8 million, or 2.4%, to $76.9
million from $75.1 million in the first half of 2001. Gross profit for the
segment increased by $0.4 million, or 5.1%, in the second quarter of 2002 to
$8.3 million (22.2% of segment net revenues) from $7.9 million (19.8% of
segment net revenues) in the second quarter of 2001. Likewise, gross profit
for the segment increased by $2.7 million, or 18.2%, in the six months ended
April 30, 2002 to $17.4 million (22.6% of segment net revenues) from $14.7
million (19.6% of segment net revenues) in the first half of 2001.
Significant gross margin improvements resulted from certain key Light
Military Support Equipment programs including contracts for Tactical Quiet
Generators and for the Chemical/Biological Protection Shelter systems.
Income from operations increased by $0.4 million, or 8.6%, in the second
quarter of 2002 to $4.4 million from $4.0 million in the second quarter of
2001, and increased by $2.5 million, or 35.0%, in the first half of 2002 to
$9.7 million from $7.2 million in the first half of 2001, as a result of the
gross profit gains noted above and due to the elimination of goodwill
amortization, which totaled $0.3 million in the second quarter of 2001 and
$0.5 million in the first half of 2001, in accordance with the adoption of
SFAS 142.

         HEAVY MILITARY SUPPORT EQUIPMENT. Net revenues for the Heavy
Military Support Equipment segment increased by $0.8 million, or 2.3%, to
$34.4 million in the second quarter of 2002 from $33.6 million in the second
quarter of 2001. For the six months ended April 30, 2002, net revenues for
the segment increased by $1.8 million, or 2.8%, to $65.4 million from $63.6
million in the first half of 2001. Gross profit for the segment increased by
$3.1 million, or 46.9%, in the second quarter of 2002 to $9.7 million (28.2%
of segment net revenues) from $6.6 million (19.6% of segment net revenues)
in the second quarter of 2001. For the six months ended April 30, 2002,
gross profit for the


                                     12

<PAGE>
<PAGE>

segment increased by $2.7 million, or 20.0%, to $16.3 million (25.0% of
segment net revenues) from $13.6 million (21.4% of segment net revenues) in
the first half of 2001. Significant gross margin improvements for the three
and six month periods ended April 30, 2002 were realized on the Tunner 60-K
Aircraft Cargo Loader/Transporter and on the M1000 Heavy Equipment
Transporter. Income from operations increased by $2.7 million, or 89.9%, in
the second quarter of 2002 to $5.7 million from $3.0 million in the second
quarter of 2001, and increased by $2.1 million, or 30.9%, in the first half
of 2002 to $9.0 million from $6.9 million in the first half of 2001, as a
result of the gross profit gains noted above and due to the elimination of
goodwill amortization, which totaled $0.3 million in the second quarter of
2001 and $0.6 million in the first half of 2001, in accordance with the
adoption of SFAS 142.

         ELECTRONICS AND AUTOMATION SYSTEMS. Net revenues for the
Electronics and Automation Systems segment decreased by $1.2 million, or
5.7%, to $20.0 million in the second quarter of 2002 from $21.2 million in
the second quarter of 2001. For the six months ended April 30, 2002, net
revenues for the segment decreased by $1.2 million, or 3.0%, to $40.7
million from $41.9 million in the first half of 2001. These decreases were
primarily due to lower revenues from the U.S. Postal Service. Gross profit
for the segment decreased by $0.4 million, or 10.2%, in the second quarter
of 2002 to $3.8 million (18.9% of segment net revenues) from $4.2 million
(19.8% of segment net revenues) in the second quarter of 2001. For the six
months ended April 30, 2002, gross profit for the segment increased by $0.2
million, or 2.7%, to $7.9 million (19.4% of segment net revenues) from $7.7
million (18.3% of segment net revenues) in the first half of 2001. Income
from operations decreased by $0.5 million, or 25.8%, in the second quarter
of 2002 to $1.4 million from $1.9 million in the second quarter of 2001, and
increased by $0.1 million, or 2.9%, in the first half of 2002 to $3.3
million from $3.2 million in the first half of 2001, as a result of the
above and due to the elimination of goodwill amortization, which totaled
$0.2 million in the second quarter of 2001 and $0.4 million in the first
half of 2001, in accordance with the adoption of SFAS 142.

         Net interest expense decreased by $1.0 million to $0.7 million in
the second quarter of 2002 and by $2.1 million to $1.5 million in the six
months ended April 30, 2002. These decreases were primarily a result of
lower outstanding borrowings on the Company's revolving and term-debt credit
facilities, as well as the impact of lower interest rates. The effective
income tax rate was 39.0% for the three and six months ended April 30, 2002
as compared to 40.0% for the three and six months ended April 30, 2001. The
reduction in the Company's effective income tax rate resulted from the
implementation of various tax planning strategies in fiscal 2001. As a
result of the foregoing, net income from continuing operations increased
50.6% to $6.6 million (7.2% of consolidated net revenues) in the quarter
ended April 30, 2002 as compared to $4.4 million (4.6% of consolidated net
revenues) in the second quarter of 2001. For the six months ended April 30,
2002, net income from continuing operations increased 52.7% to $12.5 million
(6.8% of consolidated net revenues) from $8.2 million (4.5% of consolidated
net revenues for the first half of 2001.

         As previously noted, in the second quarter of 2002 the Company
recorded an estimated loss, net of income tax, of $3.1 million related to
the disposal of ESP. In addition, the Company realized income (loss) from
ESP operations, net of income tax, of $(0.1) million and $0.1 million in the
second quarter of 2002 and 2001, respectively, and of $(0.5) million and
$0.1 million in the six months ended April 30, 2002 and 2001, respectively.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In June 2001, the Financial Accounting Standards Board (FASB)
issued Statements of Financial Accounting Standards No. 141 (SFAS 141),
"Business Combinations", and No. 142 (SFAS 142), "Goodwill and Other
Intangible Assets". Under SFAS 142, goodwill and other intangible assets
deemed to have indefinite lives will no longer be amortized, but will be
subject to periodic impairment tests. All other intangible assets will be
amortized over their useful lives. In addition, SFAS 141 eliminates the
pooling-of-interests method of accounting for business combinations. The
Company adopted SFAS 141 and SFAS 142 as of November 1, 2001 and had no
impairment of goodwill as a result of its transitional assessment.

         In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets". SFAS 144 addresses the
financial accounting and reporting for the impairment or disposal of
long-lived assets and supersedes SFAS 121. The Company adopted SFAS 144
effective November 1, 2001. In the quarter ended April 30, 2002, the Company
accounted for the planned disposition through sale of ESP as discontinued
operations in accordance with SFAS 144.

LIQUIDITY AND CAPITAL RESOURCES

         In conjunction with the acquisition of SEI in September 1999, the
Company entered into a new credit agreement to provide a $90.0 million term
loan and a $55.0 million revolving credit facility. The Company's primary
sources of short-term financing are from cost reimbursements under contracts
with the U.S. government via receipt of progress payments, billings for
delivered products and borrowings under the revolving line of credit. As of
April 30, 2002, the Company had no borrowings against the revolving line of
credit, remaining availability under the line of credit of $42.3 million and
a cash balance of $21.3 million.

         During the period ended April 30, 2002, the Company's derivative
contracts consisted only of interest rate swaps used by the Company to
convert a portion of its variable rate long-term debt to fixed rates. At
April 30, 2002, the Company recorded a liability of $0.9 million related to
the fair value of those interest rate swap agreements, which are designated
as and considered highly effective cash flow hedges of the Company's
forecasted variable rate interest payments. The entire corresponding loss,
net of income tax, was recorded in shareholders' equity as accumulated other
comprehensive loss.

           At April 30, 2002, the Company's working capital and ratio of
current assets to current liabilities were $48.6 million and 1.71 to 1 as
compared with $41.3 million and 1.59 to 1 at October 31, 2001. The Company
generated cash flow from continuing operations of $29.0 million in the six
months ended April 30, 2002 as compared to $11.1 million in the first six
months of 2001. Investment in property, plant and equipment totaled $1.7
million and $1.0 million for the first six months of 2002 and 2001,
respectively. The Company anticipates that capital expenditures in 2002
should not exceed $5.0 million. Management believes that cash flow generated
from operations, together with the available line of credit, will provide
the necessary resources to meet the needs of the Company in the foreseeable
future.

BUSINESS AND MARKET CONSIDERATIONS

         Approximately 95% of consolidated net revenues from continuing
operations for the six months ended April 30, 2002 were directly or
indirectly derived from defense orders by the U.S. government and its
agencies. As of April 30, 2002, the Company's funded backlog of orders
totaled $359.5 million, with related customer options of an additional
$581.6 million.

         Management continues to pursue potential acquisitions, primarily of
those companies providing strategic consolidation within the defense
industry. Effective May 10, 2002, the Company acquired all of the
outstanding stock of Radian, Inc., a supplier of engineering, logistics
support and systems integration services to the U.S. Department of Defense.
The purchase price was $41.8 million consisting of $39.8 million in cash and
$2.0 million in common stock of the Company. Radian, Inc. generated revenues
of approximately $53 million for the year ended December 31, 2001.

FORWARD-LOOKING STATEMENTS

         In addition to historical information, this report includes certain
forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended, which are intended to be covered by the
safe harbors created thereby. The forward-looking statements involve certain
risks and uncertainties, including, but not limited to acquisitions,
additional financing requirements, the decision of any of the Company's key
customers (including the U.S. government) to reduce or terminate orders with

increased competition in the Company's markets, which could cause the
Company's actual results to differ materially from those projected in, or
inferred by, the forward-looking statements.
