RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In October 2004, Congress passed the American Jobs Creation Act of
2004 (the Jobs Creation Act). The Jobs Creation Act includes numerous
provisions that may materially affect business practices and accounting for
income taxes. For companies that pay U.S. income taxes on manufacturing
activities in the U.S., the Jobs Creation Act provides a phased-in deduction
from taxable income equal to a stipulated percentage of qualified income
from domestic production activities. In December 2004, the FASB issued two
FASB Staff Positions (FSP) regarding the accounting implications of the Act
related to (1) the deduction for qualified domestic production activities
(FSP 109-1) and (2) the one-time tax benefit for the repatriation of foreign
earnings (FSP 109-2). This guidance applies to financial statements for
periods ending after the date the Act was enacted. The Jobs Creation Act
also provides for a change in the period of application for foreign tax
credits, elimination of the 90-percent limitation of foreign tax credits
against Alternative Minimum Tax, expanded disallowance of interest on
convertible debt, and tax shelter disclosure penalties. The Company adopted
FSP 109-1 and FSP 109-2 in the first quarter of 2005. The Company
anticipates that the Jobs Creation Act and related FASB pronouncements will
have a material impact on the Company's financial statements in future
periods. However, the Company has determined that this impact is not
material for the three and nine months ended July 31, 2005 and will not be
material for the year ending October 31, 2005.

         In November 2004, the FASB issued SFAS 151, "Inventory Costs - an
amendment of ARB No. 43, Chapter 4." SFAS 151 seeks to clarify the
accounting for abnormal amounts of idle facility expense, freight, handling
costs and wasted material (spoilage) in the determination of inventory
carrying costs. The statement requires such costs to be treated as a current
period expense. This statement is effective November 1, 2005 for the
Company. The Company does not believe that the adoption of SFAS 151 will
have a significant impact on the consolidated financial statements.

         In December 2004, the FASB issued SFAS 123 (revised 2004),
"Share-Based Payment" (SFAS 123R). SFAS 123R requires companies to expense
the value of employee stock options and similar awards. This statement is
effective November 1,


                                     7

2005 for the Company. The Company is currently evaluating its compensation
policies and practices, along with the impact of SFAS 123R on its results of
operations.

         In May 2005, the FASB issued SFAS 154, "Accounting Changes and
Error Corrections - a Replacement of APB Opinion No. 20 and FASB Statement
No. 3". SFAS 154 requires retrospective application to prior period
financial statements of changes in accounting principle, unless it is
impracticable to determine either the period-specific effects or the
cumulative effect of the change. SFAS 154 also redefines "restatement" as
the revising of previously issued financial statements to reflect the
correction of an error. This statement is effective for accounting changes
and corrections of errors made in fiscal years beginning after December 15,
2005. The Company does not believe that the adoption of SFAS 154 will have a
significant impact on the consolidated financial statements.

NOTE B - EARNINGS PER SHARE

         Average diluted common shares outstanding include common stock
equivalents, which represent common stock options as computed based on the
treasury stock method. Average basic and diluted common shares outstanding
have been restated to reflect a three-for-two stock split effected by the
Company on April 15, 2005 in the form of a stock dividend.

         Basic earnings per share for the three months ended July 31, 2005 and
2004 is based on average basic common shares outstanding of 41,717 and
39,518, respectively. Diluted earnings per share for the three months ended
July 31, 2005 and 2004 is based on average diluted common shares outstanding
of 43,379 and 42,099, respectively.

         Basic earnings per share for the nine months ended July 31, 2005
and 2004 is based on average basic common shares outstanding of 41,161 and
38,666, respectively. Diluted earnings per share for the nine months ended
July 31, 2005 and 2004 is based on average diluted common shares outstanding
of 43,068 and 41,729, respectively.

NOTE C - STOCK-BASED COMPENSATION

         The Company applies Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations in
accounting for all stock option plans. Accordingly, no compensation expense
has been recognized for stock option awards. The following table illustrates
the effect on net income from continuing operations and earnings per share
had the Company applied the fair value recognition provisions of Statement
of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation," to stock option awards.

NOTE G - NOTES PAYABLE

         On January 27, 2005, the Company entered into an Amended and
Restated Credit Agreement (Amended Credit Agreement) with its banks. The
Amended Credit Agreement replaced the Company's previous credit agreement
dated April 23, 2003. The Amended Credit Agreement, which expires January
27, 2010, provides for a $200 million unsecured revolving credit facility.
The Company may request, subject to certain conditions, an increase of up to
$100 million in the amount of the aggregate commitment under the Amended
Credit Agreement.

         Borrowings under the Amended Credit Agreement bear interest, at the
Company's option, at either the Eurodollar rate plus an applicable margin,
or at the higher of the prime rate or the federal funds rate plus one-half
of one percent. The margin applicable to the Eurodollar rate varies from
0.625% to 1.375% depending upon the Company's ratio of total indebtedness to
earnings before interest, taxes, depreciation and amortization (leverage
ratio). The Amended Credit Agreement contains certain covenants, including
maintaining net worth of at least $265 million, plus 50% of the sum, to
the extent positive, of the Company's consolidated net income and other
comprehensive income (loss) reported after October 31, 2004, plus the net
proceeds of all subsequent equity offerings. The Company must also comply
with certain financial covenants, including maintenance of a leverage ratio
of no greater than 2.75 to 1. The Company is also subject to various other
financial and operating covenants and maintenance criteria, including
restrictions on the Company's ability to incur additional indebtedness, make
investments, create liens, dispose of material assets and enter into merger
transactions and acquisitions. As of July 31, 2005, the Company had $86
million in borrowings against the Amended Credit Facility, and was in
compliance with all applicable covenants.

NOTE H - CONTRACTS IN PROCESS AND INVENTORIES

other postretirement benefit plans during 2005. The Company anticipates
contributing an additional $1,750 to fund the pension and other
postretirement benefit plans in 2005 for a total of $8,000.

NOTE L - DISCONTINUED OPERATIONS

         The Company completed the sale of Engineered Specialty Plastics,
Inc. (ESP), a wholly-owned subsidiary, in the quarter ended April 30, 2003
to a private equity group (the Buyers). The Buyers subsequently alleged that
the Company breached certain representations made under the related Stock
Purchase Agreement (the Agreement) and sought a claim for associated damages
under the binding arbitration provisions of the Agreement. During the
quarter ended April 30, 2005, the Company and the Buyers reached a
settlement on this claim, which included modification of the Company's $3.2
million note receivable from the Buyers to provide for suspension of
interest charges and payments through July 31, 2006, extension of the note's
repayment term to a balloon payment now due in April 2009, and the release
of the underlying real estate collateral securing the note. Because of this
settlement, the Company recorded a charge for the impairment of the note
during the quarter ended April 30, 2005 equal to $1.7 million, or $1.0
million net of income tax. This amount is reflected in discontinued
operations on the Condensed Consolidated Statements of Income for the nine
months ended July 31, 2005.

NOTE M - STOCK SPLIT

         On April 15, 2005, the Company effected a three-for-two stock split
in the form of a 50% stock dividend. All per share amounts in this report
have been restated to reflect this split.

        CONDITION AND RESULTS OF OPERATIONS.

CRITICAL ACCOUNTING POLICIES

and Results of Operations from the Company's 2004 Annual Report to
Shareholders in the Company's Annual Report on Form 10-K for the year

       The following analysis should be read in this context.

RESULTS OF OPERATIONS

         Consolidated net revenues increased $36.7 million, or 16.6%, to
$258.7 million in the third quarter of 2005 compared to $222.0 million in
the third quarter of 2004. $29.2 million of this $36.7 million increase was
generated by the Company's most recently acquired subsidiaries - Prospective
Computer Analysts Incorporated (PCA) which was acquired January 7, 2005,
Spacelink International, LLC (Spacelink) which was acquired February 1,
2005, and Mobilized Systems, Inc. (MSI) which was acquired May 1, 2005. The
remaining $7.5 million increase from existing operations included additional
revenues from refurbishment of M1000 Heavy Equipment Transporter ($8.5
million increase), the installation of vehicle uparmor kits ($22.6 million
increase) and the Rapid Response (R2) contract vehicle ($18.7 million
increase). These revenue increases were offset by reduced work on the 60-K
Tunner Aircraft Cargo Loader ($16.3 million decrease) as the production
phase of this long-term program ended in the quarter ended April 30, 2005,
reduced deliveries of the Manportable Surveillance and Target Acquisition
Radar (MSTAR) perimeter security program for which a large base security
subcontract with Northrup Grumman was completed in the fourth quarter of
2004 ($21.2 million decrease) and production delays on the Deployable Power
Generation and Distribution System (DPGDS), which had been encountering
performance issues on the primary power unit component of the program ($11.2
million decrease). In August 2005, the Company successfully completed
reliability testing on the primary power units. As a result, the Company's
U.S. Air Force customer has lifted a related stop work order on the 30
primary power units under the K3 portion of this contract, which had been
previously imposed on the Company. The Company's formal report on its
reliability testing will be issued to the U.S. Air Force in September 2005
and the Company expects that the evaluation of this report will result in
the removal of the stop work order on the remaining 65 primary power units
under the K4 portion of the DPGDS contract. As a result, the Company expects
that the DPGDS program will return to full rate production in the fourth
quarter of 2005. Gross profit for the quarter ended July 31, 2005 increased
$6.6 million, or 11.7%, to $63.4 million (24.5% of consolidated net
revenues) from $56.8 million (25.6% of consolidated net revenues) in the
comparable 2004 period. Substantially all of this gross profit increase
($6.2 million) was derived from the PCA, Spacelink and MSI acquisitions.
Selling, general and administrative expense increased $4.2 million, or 19.1%
in the third quarter of 2005 to $26.4 million (10.2% of consolidated net
revenues) from $22.1 million (10.0% of consolidated net revenues) in the
third quarter of 2004. Selling, general and administrative expense for PCA,
Spacelink and MSI accounted for $4.1 million of the $4.2 million increase.
As a result of the above, operating income from continuing

                                     19

operations increased $3.7 million, or 11.0%, in the quarter ended July 31,
2005 to $37.1 million from $33.4 million in the third quarter of 2004.


         Consolidated net revenues increased $128.7 million, or 20.5%, to
$756.0 million in the first nine months of 2005 compared to $627.3 million
in the first nine months of 2004. $55.6 million of this $128.7 million
increase was generated by the Company's most recently acquired subsidiaries
(PCA, Spacelink and MSI). The remaining $73.1 million increase from existing
operations included additional revenues from refurbishment of M1000 Heavy
Equipment Transporters ($24.3 million increase), the installation of vehicle
uparmor kits ($55.5 million increase) and the R2 contract vehicle ($49.3
million increase). These revenue increases were offset by reduced work on
the 60-K Tunner Aircraft Cargo Loader ($30.1 million decrease), reduced
MSTAR deliveries ($52.7 million decrease) and reduced DPGDS production
($14.2 million decrease). Gross profit for the nine months ended July 31,
2005 increased $24.8 million, or 15.8%, to $181.3 million (24.0% of
consolidated net revenues) from $156.5 million (25.0% of consolidated net
revenues) in the comparable 2004 period. Revenue growth of $128.7 million
resulted in the increase in gross profit. However, lower gross margins for
the first nine months of 2005 reflect a less favorable revenue mix,
primarily resulting from a greater percentage of generally lower margin
Support Services segment revenues, as well as the impact of production
delays and increased estimated costs resulting from performance issues with
the primary power unit component of the DPGDS program. Selling, general and
administrative expense increased $12.5 million, or 19.0%, in the first nine
months of 2005 to $78.0 million (10.3% of consolidated net revenues) from
$65.5 million (10.4% of consolidated net revenues) in the first nine months
of 2004. Selling, general and administrative expense for PCA, Spacelink and
MSI accounted for $7.7 million of the $12.5 million increase, with the
remaining increase required to support higher operating levels. As a result
of the above, operating income from continuing operations increased $13.7
million, or 15.3%, in the first nine months of 2005 to $103.3 from $89.6
million in the first nine months of 2004.

         SUPPORT SYSTEMS. Net revenues in the third quarter of 2005 for the
Support Systems segment totaled $133.0 million compared to $134.9 million
(prior to the elimination of intersegment revenues in each period) for the
same period in the prior year, a 1.4% decrease. The results for the quarter
ended July 31, 2005 reflect the inclusion of $9.4 million in incremental net
revenues from PCA and MSI. During the quarter the segment experienced a
$16.3 million revenue reduction on the 60-K Tunner Aircraft Cargo Loader, as
the production phase of this long-term program was completed in the quarter
ended April 30, 2005, as well as a $21.2 million revenue reduction on the MSTAR
program, for which a large base security subcontract for Northrup Grumman
was completed in the fourth quarter of 2004. These decreases were offset by
an $8.5 million revenue increase from refurbishment of M1000 Heavy Equipment
Transporters and by a $20.1 million increase in intersegment work performed
for the Support Services segment. Gross profit for the segment decreased by
$3.8 million, or 9.5%, in the quarter ended July 31, 2005 to $36.1 million
(27.1% of segment revenues) from $39.9 million (29.6% of segment revenues)
in the prior year quarter as a result of the above revenue decreases, as
well as a shift to lower margin programs, in spite of a $2.8 million gross
profit contribution from PCA and MSI. Quarterly operating income for the
segment decreased to $21.4 million (16.1% of segment revenues) compared to
$24.3 million (18.0% of segment revenues) last year. Decreased revenues and
related gross profit reductions, despite a $0.9 million, or approximately
5.8%, decrease is segment selling, general and administrative expense led to
the lower results for the Support Systems segment.
         Net revenues in the first nine months of 2005 for the Support
Systems segment totaled $379.6 million compared to $376.7 million (prior to
the elimination of intersegment revenues in each period) for the same period
in the prior year, a 0.8% increase. The results for the nine months ended
July 31, 2005 reflect the inclusion of $14.4 million in incremental net
revenues from PCA and MSI during the first nine months of 2005. During this
period, the segment experienced a $30.1 million revenue reduction on the
60-K Tunner Aircraft Cargo Loader and a $52.7 million revenue reduction
on the MSTAR program. These decreases were offset by a $24.3 million revenue
increase from refurbishment of M1000 Heavy Equipment Transporters and by a
$43.5 million increase in intersegment work performed for the Support
Services segment. Gross profit for the segment decreased by $2.5 million, or
2.2%, in the nine months ended July 31,


                                     21

2005 to $111.3 million (29.3% of segment revenues) from $113.8 million
(30.2% of segment revenues) in the first nine months of the prior year, in
spite of a $4.4 million gross profit contribution from PCA and MSI. Segment
operating income for the nine months ended July 31, 2005 decreased to $66.9
million (17.6% of segment revenues) compared to $71.6 million (19.0% of
segment revenues) last year primarily as a result of gross profit reductions
and a $2.2 million increase in segment selling, general and administrative
expense.

         SUPPORT SERVICES. Net revenues for the Support Services segment
increased to $154.8 million, an increase of $52.3 million, or 51.0%,
compared to $102.5 million (prior to the elimination of intersegment
revenues in each period) for the third quarter of 2005. The most significant
year-over-year revenue increases were generated by the R2 contract vehicle
($18.7 million) and the vehicle uparmor kit program ($22.6 million). In
addition, Spacelink (acquired effective February 1, 2005) added $19.8
million of incremental revenues in the third quarter of 2005. Offsetting
these increases were decreased revenues from the DPGDS program of $11.2
million. Gross profit for the segment increased by $10.7 million, or 63.2%,
in the quarter ended July 31, 2005 to $27.6 million (17.8% of segment
revenues) from $16.9 million (17.6% of segment revenues) in the prior year
quarter primarily as a result of increased revenues. Segment operating
income for the third quarter of 2005 totaled $15.6 million (10.1% of segment
revenues) compared to $9.1 million (8.9% of segment revenues) in the same
period last year. Although incremental revenues and related gross profit
contributions led to the overall improved results for the Support Services
segment, the segment's operating profit for the third quarter of 2005 was
constrained by a decrease of $5.2 million in DPGDS gross profit compared to
the third quarter of 2004. The Company expects that the DPGDS program will
return to full rate production in the fourth quarter of 2005.

         Net revenues for the Support Services segment increased to $439.9
million, an increase of $145.9 million, or 49.6%, compared to $294.0 million
(prior to the elimination of intersegment revenues in each period) for the
first nine months of 2005. The most


                                     22


<PAGE>
<PAGE>

significant year-over-year revenue increases were generated by the R2
contract vehicle ($49.3 million) and the vehicle uparmor kit program ($55.5
million). In addition, Spacelink added $41.1 million of incremental revenues
in the first nine months of 2005. Offsetting these increases were decreased
revenues from the DPGDS program of $14.2 million as previously discussed.
Gross profit for the segment increased by $27.6 million, or 64.5% in the
nine months ended July 31, 2005 to $70.3 million (16.0% of segment revenues)
from $42.7 million (15.7% of segment revenues) in the first nine months of
2004 primarily as a result of increased revenues. Segment operating income
for the first nine months of 2005 totaled $36.4 million (8.3% of segment
revenues) compared to $18.0 million (6.1% of segment revenues) in the same
period last year. The $145.9 million increase in segment revenues provided
significant gross profit increases as well as leveraging existing fixed
overhead costs, which led to the overall improved results for the Support
Services segment. Segment profitability was constrained by a decrease of
$7.5 million in DPGDS gross profit compared to the first nine months of
2004.

         CONSOLIDATED RESULTS OF OPERATIONS. Net interest expense totaled
$0.7 million in the third quarter of 2005 compared to $0.1 million in the
third quarter of 2004 as a result of increased borrowing levels necessary
for the acquisitions of PCA, Spacelink and MSI in 2005. Net interest expense
totaled $1.3 million and $0.9 million for the nine months ended July 31,
2005 and 2004, respectively. The effective income tax rate was 38.0% for the
three and nine month periods ended July 31, 2005 compared to 38.5% for the
three and nine month periods ended July 31, 2004. This reduction is
primarily a result of the Company's ongoing state income tax reduction
initiatives. As a result of the foregoing, net income from continuing
operations increased 10.0% to $22.6 million (8.7% of consolidated net
revenues) in the quarter ended July 31, 2005 as compared to $20.5 million
(9.2% of consolidated net revenues) in the third quarter of 2004, and net
income from continuing operations increased 15.9% to $63.3 million (8.4% of
consolidated net revenues) in the first nine months of 2005 as compared to
$54.6 million (8.7% of consolidated net revenues) in the first nine months
of 2004.

                                     23


<PAGE>
<PAGE>

         Based on third quarter results, existing backlog and anticipated
orders, the Company anticipates that 2005 revenues will approximate $1.02
billion to $1.05 billion, and that earnings per share from continuing
operations will approximate between $2.00 and $2.03.

         DISCONTINUED OPERATIONS. The Company completed the sale of
Engineered Specialty Plastics, Inc. (ESP), a wholly-owned subsidiary, in the
quarter ended April 30, 2003 to a private equity group (the Buyers). The
Buyers subsequently alleged that the Company breached certain
representations made under the related Stock Purchase Agreement (the
Agreement) and sought a claim for associated damages under the binding
arbitration provisions of the Agreement. During the quarter ended April 30,
2005, the Company and the Buyers reached a settlement on this claim, which
included modification of the Company's $3.2 million note receivable from the
Buyers to provide for suspension of interest charges and payments through
July 31, 2006, extension of the note's repayment term to a balloon payment
now due in April 2009, and the release of the underlying real estate
collateral securing the note. Because of this settlement, the Company
recorded a charge for the impairment of the note during the quarter ended
April 30, 2005 equal to $1.7 million, or $1.0 million net of income tax.
This amount is reflected in discontinued operations on the Condensed
Consolidated Statements of Income for the nine months ended July 31, 2005.



RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In October 2004, Congress passed the American Jobs Creation Act of
2004 (the Jobs Creation Act). The Jobs Creation Act includes numerous
provisions that may materially affect business practices and accounting for
income taxes. For companies that pay U.S. income taxes on manufacturing
activities in the U.S., the Jobs Creation Act provides a phased-in deduction
from taxable income equal to a stipulated percentage of qualified income
from domestic production activities. In December 2004, the FASB issued two
FASB Staff Positions (FSP) regarding the accounting implications of the Act

                                     24


<PAGE>
<PAGE>

related to (1) the deduction for qualified domestic production activities
(FSP 109-1) and (2) the one-time tax benefit for the repatriation of foreign
earnings (FSP 109-2). This guidance applies to financial statements for
periods ending after the date the Act was enacted. The Jobs Creation Act
also provides for a change in the period of application for foreign tax
credits, elimination of the 90-percent limitation of foreign tax credits
against Alternative Minimum Tax, expanded disallowance of interest on
convertible debt, and tax shelter disclosure penalties. The Company adopted
FSP 109-1 and FSP 109-2 in the first quarter of 2005. The Company
anticipates that the Jobs Creation Act and related FASB pronouncements will
have a material impact on the Company's financial statements in future
periods. However, the Company has determined that this impact is not
material for the three and nine months ended July 31, 2005 and will not be
material for the year ending October 31, 2005.

         In November 2004, the FASB issued SFAS 151, "Inventory Costs - an
amendment of ARB No. 43, Chapter 4." SFAS 151 seeks to clarify the
accounting for abnormal amounts of idle facility expense, freight, handling
costs and wasted material (spoilage) in the determination of inventory
carrying costs. The statement requires such costs to be treated as a current
period expense. This statement is effective November 1, 2005 for the
Company. The Company does not believe that the adoption of SFAS 151 will
have a significant impact on the consolidated financial statements.

         In December 2004, the FASB issued SFAS 123 (revised 2004),
"Share-Based Payment", (SFAS 123R). SFAS 123R requires companies to expense
the value of employee stock options and similar awards. This statement is
effective November 1, 2005 for the Company. The Company is currently
evaluating its compensation policies and practices, along with the impact of
SFAS 123R on its results of operations.

         In May 2005, the FASB issued SFAS 154, "Accounting Changes and
Error Corrections - a Replacement of APB Opinion No. 20 and FASB Statement
No. 3". SFAS 154 requires retrospective application to prior period
financial statements of changes in accounting principle, unless it is
impracticable to determine either the period-


                                     25


<PAGE>
<PAGE>

specific effects or the cumulative effect of the change. SFAS 154 also
redefines "restatement" as the revising of previously issued financial
statements to reflect the correction of an error. This statement is
effective for accounting changes and corrections of errors made in fiscal
years beginning after December 15, 2005. The Company does not believe that
the adoption of SFAS 154 will have a significant impact on the consolidated
financial statements.


LIQUIDITY AND CAPITAL RESOURCES

         On January 27, 2005, the Company entered into an Amended and
Restated Credit Agreement (Amended Credit Agreement) with its banks. The
Amended Credit Agreement replaced the Company's previous credit agreement
dated April 23, 2003. The Amended Credit Agreement, which expires January
27, 2010, provides for a $200 million unsecured revolving credit facility.
The Company may request, subject to certain conditions, an increase of up to
$100 million in the amount of the aggregate commitment under the Amended
Credit Agreement.

         Borrowings under the Amended Credit Agreement bear interest, at the
Company's option, at either the Eurodollar rate plus an applicable margin,
or at the higher of the prime rate or the federal funds rate plus one-half
of one percent. The margin applicable to the Eurodollar rate varies from
0.625% to 1.375% depending upon the Company's ratio of total indebtedness to
earnings before interest, taxes, depreciation and amortization (leverage
ratio). The Amended Credit Agreement contains certain covenants, including
maintaining net worth of at least $265 million, plus 50% of the sum, to
extent positive, of the Company's consolidated net income and other
comprehensive income (loss) reported after October 31, 2004, plus the net
proceeds of all subsequent equity offerings. The Company must also comply
with certain financial covenants, including maintenance of a leverage ratio
of no greater than 2.75 to 1. The Company is also subject to various other
financial and operating covenants and maintenance criteria, including
restrictions on the Company's ability to incur additional indebtedness, make
investments, create liens, dispose of material assets and enter into merger
transactions


                                     26


<PAGE>
<PAGE>

and acquisitions. As of July 31, 2005, the Company had $86.0 million in
borrowings against the Amended Credit Facility, and was in compliance with
all applicable covenants.


         Effective May 1, 2005, the Company acquired all of the outstanding
stock of MSI, which designs, manufacturers and tests highly specialized
trailers, shelters and environmental control systems, primarily for the
defense industry. The purchase price was $17.5 million, net of cash
acquired. $15.7 million of the purchase price has been paid as of July 31,
2005, with an additional $1.0 million accrued as of that date related to the
final working capital adjustment. The remaining $0.8 million of
consideration is in the form of long-term promissory notes payable to the
sellers. The purchase price is being financed with short-term borrowings
under the Company's revolving credit facility. The fair value of assets
acquired, including goodwill of $12.7 million and customer-related
intangibles of $3.2 million, was $19.1 million and liabilities assumed
totaled $1.6 million.


         Effective February 1, 2005, the Company acquired all of the
outstanding stock of Spacelink, which designs, integrates, operates and
maintains deployed satellite and wireless networks for the U.S. Department
of Defense (DOD), the U.S. intelligence community and other forward deployed
federal agencies and multinational organizations worldwide. The purchase
price, including transaction costs, was $149.7 million, which included
consideration of $13.2 million in the common stock of the Company and cash
consideration financed with short-term borrowings under the Company's
revolving credit facility. The purchase price is net of $1.8 million of cash
acquired. The purchase price is also subject to a working capital adjustment
and to certain contingent cash consideration based upon Spacelink's earnings
before interest, taxes, depreciation and amortization, as defined, for each
of the twelve month periods ending January 31, 2006 and 2007. The fair value
of assets acquired, including goodwill of $120.9 million and acquired
customer-related intangibles of $13.8 million, was $159.7 million and
liabilities assumed totaled $10.0 million.



         On January 7, 2005, the Company acquired all of the outstanding
stock of PCA, which develops and manufactures electronic test and
measurement equipment provided for electronic warfare and avionics systems
primarily to military customers. The purchase price was $37.6 million and is
subject to a working capital adjustment. The purchase price was financed
with the Company's existing cash balances. The fair value


                                     27


<PAGE>
<PAGE>

of assets acquired, including goodwill of $24.1 million and acquired
customer-related intangibles of $6.4 million, was $38.1 million and
liabilities assumed totaled $0.5 million.


         At July 31, 2005, the Company's working capital and ratio of
current assets to current liabilities were $44.0 million and 1.20 to 1 as
compared with $112.0 million and 1.85 to 1 at October 31, 2004. The
significant changes in working capital and the ratio of current assets to
current liabilities from October 31, 2004 are due to the increase in
short-term borrowings against the Company's revolving credit facility, which
were required as a result of the PCA, Spacelink and MSI acquisitions. Net
cash provided by operations totaled $59.2 million for the first nine months
of 2005 compared to net cash provided by operations of $19.0 million for the
first nine months of 2004. Investment in property, plant and equipment
totaled $7.7 million and $6.2 million for the first nine months of 2005 and
2004, respectively. The Company anticipates that capital expenditures in
2005 should not exceed $15.0 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.

         During the nine months ended July 31, 2005 and 2004, the Company
received proceeds of $27.3 million and $56.3 million, respectively, related
to the exercise of stock options.


BUSINESS AND MARKET CONSIDERATIONS

         Approximately 93% of consolidated net revenues for the nine months
ended July 31, 2005 were directly or indirectly derived from defense orders
by the U.S. government and its agencies. As of July 31, 2005, the Company's
funded backlog of orders totaled $612.8 million, with related customer
options of an additional $1,655.4 million. These amounts compare to funded
backlog of $588.1 million and related customer options of an additional
$849.2 million as of October 31, 2004.

         The Company anticipates that 2006 revenues will approximate $1.20
to $1.25 billion, and that earnings per share from continuing operations
will approximate between $2.20 and $2.30.

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

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, which could cause the Company's actual results to
differ materially from those projected in, or inferred by, the
forward-looking statements, 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
the Company, cutbacks in defense spending by the U.S. government and
increased competition in the Company's markets and other risks discussed in
the Company's reports filed with the Securities and Exchange Commission from
time to time.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

       Market risks relating to the Company's operations result primarily
from changes in interest rates. Given existing debt levels, significant cash
flows and anticipated expenditures, Company management has not utilized
interest rate swaps or other derivative contracts to hedge this risk since
November 2002. Management does not believe its exposure to interest rate
fluctuations has had, or will have, a significant impact on the Company's
operations.


ITEM 4. CONTROLS AND PROCEDURES.

       As of July 31, 2005, the Company carried out an evaluation, under the
supervision and with the participation of the Company's management,
including the Company's Chief Executive Officer and Chief Financial Officer,
of the effectiveness of the design and operation of the Company's disclosure
controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based
upon the evaluation, the Company's Chief Executive Officer and Chief
Financial Officer concluded that the Company's disclosure controls and
procedures are effective.
