NOTE D - ADOPTION OF SFAS 133

     On November 1, 2000, the Company adopted Statement of Financial
Accounting Standards No. 133 (SFAS 133), "Accounting for Derivative
Instruments and Hedging Activities", as amended by SFAS 137 and SFAS
138.  The effect of adopting SFAS 133 was immaterial based on the fair
value of the Company's derivative instruments at the date of adoption.

     In accordance with SFAS 133, derivative financial instruments are
recognized on the balance sheet at fair value.  Changes in the fair
value of a derivative instrument designated as "fair value" hedges,
along with the corresponding change in fair value of the hedged asset or
liability, are recorded in current period earnings.  Changes in the fair
value of derivative instruments designated as "cash flow" hedges, to the
extent the hedges are highly effective, are recorded in other
comprehensive income, net of related tax effects.  The ineffective
portion of the cash flow hedge, if any, is recognized in current period
earnings.  Other comprehensive income is relieved when current earnings
are effected by the variability of cash flows.

     The Company formally documents the relationship between hedging
instruments and hedged items as well as its risk management objective
and strategy for undertaking its hedging activities.  The Company
formally designates derivatives as hedging instruments on the date the
derivative contract is entered into.  This process includes linking
derivative instruments designated as hedges to specific assets,
liabilities or firm commitments, or to specific forecasted transactions.
The Company evaluates, both at inception of the hedge and on an ongoing
basis, whether derivatives used as hedging instruments are highly
effective in offsetting the changes in the fair value or cash flows of
hedged items.  If it is determined that a derivative is not highly
effective as a hedge or ceases to be highly effective, the Company
discontinues hedge accounting prospectively.

     During the period ended April 30, 2001, 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, 2001, the Company recorded a liability of $1,026 ($616 after
income tax effects) 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 was recorded in accumulated other
comprehensive income (equity), net of income



                                    7




tax effects.  The Company does not expect to reclassify any of this loss
to current earnings during the next twelve months.



NOTE E - SEGMENT INFORMATION

     The Company operates in four segments: light military support
equipment, heavy military support equipment, electronics and automation
systems, and plastic products.  Intersegment revenues for the three and

for the six months ended April 30, 2001 to $75.1 million from $80.7
million for the first half of 2001.  Net revenues from the heavy
military support equipment segment increased by $10.4 million in the
second quarter of 2001 to $33.7 million as compared to $23.3 million in
the second quarter of 2000.  Net revenues for this segment increased by
$8.8 million for the six months ended April 30, 2001 to $63.7 million
from $54.9 million for the first half of 2000.  The increase in revenues
is partly due to the impact of the work stoppage that occurred at this
segment's manufacturing facilities in the second quarter of the prior
year.  As a result, segment revenues were negatively impacted by
between $6.0 to $7.0 million. Net revenues from the electronics and
automation segment increased $8.0 million in the second quarter of 2001
to $21.2 million as compared to $13.2 million in the second quarter of
2000 and increased $16.4 million for the six months ended April 30, 2001
to $41.9 million from $25.5 million.  This increase was due to
additional work performed on several major programs during the period.
Net revenues for the plastic products segment decreased $1.0 million in
the second quarter of 2001 to $5.5 million as compared to $6.5 million
for the second quarter of 2000 and decreased $0.9 million for the six
months ended April 30, 2001 to $10.5 million from $11.4 million.

     Gross Profit.  Consolidated gross profit for the second quarter of
2001 increased 20.8% to $19.4 million (19.4% of consolidated net
revenues) from $16.1 million (18.7% of consolidated net revenues) in the
second quarter of 2000.  For the six months ended April 30, 2001
consolidated gross profit increased 16.3% to $37.4 million (19.6% of
consolidated net revenues) from $32.1 million (18.6% of consolidated net
revenues) in the first half of 2000.  Gross profit for the light
military support equipment segment increased to $7.9 million (19.8% of
segment net revenues) from $7.6 million (17.7% of segment net revenues)
for the second quarter of 2000.  For the six months ended April 30,
2001, gross profit for the light military segment was $14.7 million
(19.6% of segment net revenues) compared to $14.7 million (18.2% of
segment net revenues) for the first half of 2000.  Gross profit for the
heavy military segment increased to $6.6 million (19.6% of segment
revenues) from $4.6 million (19.5% of segment net revenues) in the
second quarter of 2000, and for the six months ended April 30, 2001
gross profit increased to $13.6 million (21.4% of segment revenues) from
$10.9 million (19.8% of segment revenues) in the first half of 2000.
These increases coincide with the increase in net revenues for the same
period as a result of the work stoppage previously mentioned.  Gross
profit for the electronics and automation systems segment increased to
$4.2 million (19.8% of segment net revenues) from $3.2 million (24.5%
of segment net revenues).  For the six months ended April 30,


                                    9




2001, gross profit for the electronics and automation segment increased
to $7.7 million (18.3% of segment net revenues) from $5.3 million (20.9%
of segment net revenues).  These increases are a result of the increase
in segment revenues for the period.  Gross profit for the plastic
products segment was $0.7 million (13.2% of segment revenues) in the
second quarter of 2001 compared to $0.7 million (10.2% of segment net
revenues).  For the six months ended April 30, 2001, gross profit for
the plastic product segment was $1.3 million (12.6% of segment revenues)
compared to $1.3 million (11.2% of segment net revenues) for the same
period in 2000.

     Selling, General and Administrative Expense.  Consolidated
selling, general and administrative expenses increased by $0.7 million,
or 7.9%, to $10.3 million (10.3% of consolidated net revenues) in the
second quarter of 2001 from $9.6 million (11.1% of consolidated net
revenues) in the second quarter of 2000.  For the first half of 2001,
consolidated selling, general and administrative expense increased by
$1.0 million, or 5.5%, to $19.9 million (10.4% of consolidated net
revenues) from $18.9 million (11.0% of consolidated net revenues) for
the first six months of 2000.

     Income from Operations.  Consolidated income from operations
increased by $2.6 million, or 39.7%, to $9.1 million in the second
quarter of 2001 from $6.5 million in the second quarter of 2000.  For
the first half of 2001, consolidated income from operations increased by
$4.3 million, or 31.9% to $17.5 million from $13.2 million for the same
period in 2000.  Income from operations for the light military support
equipment segment decreased to $4.0 million in the second quarter of
2001 from $4.8 million in the second quarter of 2000, and decreased to
$7.2 million for the first six months of 2001 from $8.9 million for the
first half of 2000.  The decrease is a result of the decreased segment
net revenues and higher operating costs.  Income from operations for the
heavy military support equipment segment increased to $3.0 million in
the second quarter of 2001 from $0.7 million in the prior year, and
increased to $6.8 million for the six months ended April 30, 2001 from
$2.8 million for the same period in 2000.  These increases are a result
of higher segment revenues resulting from the work stoppage in the prior
year and lower operating costs for the fiscal 2001 periods.  The Company
estimates that income from operations for the second quarter of 2000 was
reduced by approximately $1.2 to $1.5 million as a result of the
stoppage.  Income from operations for the electronics and automation
systems segment increased to $1.9 million in the second quarter of 2001
from $1.1 million in the second quarter of 2000, and increased to $3.2
million for the first six months of 2001 from $1.6 million for the first
half of 2000 as a result of the higher segment net revenues.  Income
from operations for the plastic products segment was $0.1 million in the
second quarter of 2001 compared to breakeven in the second quarter of
2000, and increased to $0.2 million for the first six months of 2001
from a loss of $0.1 million for the same period of 2000.

     Interest Expense and Interest Income.  Net interest expense
decreased $0.6 million to $1.7 million in the second quarter of 2001
compared to $2.3 million in the second quarter of 2000, and decreased by
$1.1 million to $3.6 million in the first six months of 2001 compared to
$4.7 million in the prior year as a result of lower borrowings on the
Company's revolving and term debt facilities as compared to the prior
year and a decrease in interest rates in 2001.

     Income Tax Provision.  The effective income tax rate was 40.0% for
the quarters ended April 30, 2001 and 2000, and was 40.0% for the six
month periods ended April 30, 2001 and 2000.

     Net Income.  As a result of the forgoing, net income of the
Company increased by 72.9% to $4.4 million (4.4% of net revenues) for
the quarter ended April 30, 2001 from $2.6 million (3.0% of



                                    10




net revenues) for the second quarter of 2000.  For the first half of
2001, net income increased by 61.1% to $8.3 million (4.3% of net
revenues) from $5.1 million (3.0% of net revenues) for the comparable
period in 2000.

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, 2001, the Company had $13.0
million outstanding against the revolving line of credit, remaining
availability under the line of credit of $35.4 million, and a cash
balance of $2.0 million.

     On November 1, 2000, the Company adopted Statement of Financial
Accounting Standards No. 133 (SFAS 133), "Accounting for Derivative
Instruments and Hedging Activities", as amended by SFAS 137 and SFAS
138.  The effect of adopting SFAS 133 was immaterial based on the fair
value of the Company's derivative instruments at the date of adoption.

     During the period ended April 30, 2001, 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, 2001, the Company recorded a liability of approximately
$1.0 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 was recorded in accumulated other
comprehensive income (equity), net of income tax effects.  The Company
does not expect to reclassify any of the loss to current earnings during
the next twelve months.

     At April 30, 2001, the Company's working capital and ratio of
current assets to current liabilities were $20.8 million and 1.26 to 1
as compared with $17.1 million and 1.20 to 1 at October 31, 2000.  The
Company generated cash flow from operations of $12.1 million in the six
months ended April 30, 2001 as compared to $9.7 million in the first
half of 2000.  Investment in property, plant and equipment totaled $1.2
million and $1.5 million for the first six months of 2001 and 2000,
respectively.  The Company anticipates that capital expenditure in 2001
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 89% of consolidated net revenues for the six months
ended April 30, 2001 were directly or indirectly derived from defense
orders by the U.S. government and its agencies.  As of April 30, 2001,
the Company's funded backlog of orders totaled $364.8 million, with
related customer options of an additional $517.5 million.

     Management continues to pursue potential acquisitions, primarily
of those companies providing strategic consolidation within the defense
industry.
