                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.    BASIS OF PRESENTATION

      The accompanying consolidated financial statements, in the opinion of
      management, include all adjustments, consisting only of normal recurring
      accruals, necessary for a fair presentation of the results for the interim
      periods presented. The consolidated financial statements are presented in
      accordance with the requirements of Form 10-Q and consequently do not
      include all the disclosures required by generally accepted accounting
      principles. For further information refer to the consolidated financial
      statements and notes thereto included in the Company's Annual Report on
      Form 10-K for the year ended September 30, 2000. Certain prior year
      amounts have been reclassified to conform to the fiscal 2001 presentation.

      The results for the three month period ended December 31, 2000 are not
      necessarily indicative of the results for the entire 2001 fiscal year.


2.    EARNINGS PER SHARE

      Basic earnings per share is calculated using the weighted average number
      of common shares outstanding during the period. Diluted earnings per share
      is calculated using the weighted average number of common shares
      outstanding during the period plus shares issuable upon the assumed
      exercise of dilutive common share options and performance shares by using
      the treasury stock method. The number of shares used in the calculation of
      earnings per share for each period presented is as follows (in thousands):

      Options to purchase approximately 15,500 shares of common stock at a price
      of $19.22 per share and options to purchase 395,000 shares of common stock
      at approximately $11.44 - $19.22 were outstanding during the three month
      periods ended December 31, 2000 and 1999, respectively, but were not
      included in the respective computations of diluted EPS because the
      options' exercise price was greater than the average market price of the
      common shares. These options expire in various periods through 2010.
      Approximately 136,000 performance shares were outstanding but unearned at
      December 31, 1999, and therefore, were not included in the respective
      computation of diluted EPS.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
         FINANCIAL CONDITION




RESULTS OF OPERATIONS - Three months ended December 31, 2000 compared with
                        three months ended December 31, 1999.

NET SALES

Net sales increased $17.0 million or 25.8% to $82.9 million for the first
quarter of fiscal 2001 compared to net sales of $65.9 million for the first
quarter of fiscal 2000 primarily due to the acquisitions of Lindgren, Holaday
and the Eaton space products businesses in the second half of fiscal 2000.

Filtration/Fluid Flow

Net sales of $44.2 million in the first quarter of fiscal 2001 were $1 million
higher than prior year sales of $43.2 million. The increase is primarily the
result of the Eaton El Segundo, CA space products acquisition which contributed
$1.9 million to sales in the first quarter of fiscal 2001. In addition, sales
increases were seen in the aerospace aftermarket. Also, sales decreased by
approximately $1.8 million primarily resulting from accelerated deliveries in
the first quarter of fiscal 2000 in anticipation of Y2K computer issues.

Test

Net sales increased $13.0 million or 149% to $21.7 million in the first quarter
of fiscal 2001 from $8.7 million for the first quarter of fiscal 2000. The large
increase is primarily due to the Lindgren and Holaday acquisitions, which
contributed approximately $12 million and $1.4 million, respectively, to sales
in the first quarter of fiscal 2001.

Communications

Net sales of $14.3 million in the first quarter of fiscal 2001 were $3.8 million
or 36.2% higher than the $10.5 million of sales recorded in the first quarter of
fiscal 2000. The increase is the result of significantly higher shipments to the
Puerto Rico Electric Power Authority (PREPA) and electric utility Cooperatives
(Coops) to provide Automatic Meter Reading (AMR) systems.

Other

Sales were $2.7 million in the first quarter of fiscal 2001 and $3.5 million in
the same period of fiscal 2000. The decrease is due to the sale of the Rantec
microwave antenna business which occurred in February 2000. Rantec's microwave
antenna business contributed approximately $1.5 million to sales during the
first quarter to fiscal 2000.

ORDERS AND BACKLOG

Firm order backlog was $195.3 million at December 31, 2000, compared with $145.4
million at September 30, 2000. Orders totaling $136.1 million were received in
the first quarter of fiscal 2001. In December 2000, the Company received a $50
million follow-on contract from PREPA. The deliveries under this contract begin
in June 2001 and will be substantially completed by June 2004.

GROSS PROFIT

The gross profit margin was 30.5% in the first quarter of fiscal 2001 and 29.8%
in the first quarter of fiscal 2000. The gross margin increased compared to the
2000 results primarily due to the fiscal 2000 acquisitions and favorable changes
in sales mix.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Selling, general and administrative (SG&A) expenses for the first quarter of
fiscal 2001 were $16.8 million, or 20.2% of net sales, compared with $13.8
million, or 20.9% of net sales for the prior year period. The percentage
decrease in 2001 is the result of favorable sales leverage achieved on the
higher sales volume. The increase of $3 million in the first quarter of fiscal
2001 is mainly due to the fiscal 2000 acquisitions.

OPERATING PROFIT

Operating profit of $8.5 million (10.2% of sales) for the first quarter of
fiscal 2001 increased $2.6 million or 44.3% from operating profit of $5.9
million (8.9% of sales) for the first quarter of fiscal 2000, mainly due to the
acquisitions of Lindgren, Holaday and the Eaton El Segundo, CA space products
business in the second half of fiscal 2000.

Filtration/Fluid Flow

Operating profit was $3.0 million in fiscal 2001 and $3.4 million in fiscal
2000. The current year was impacted by costs related to the consolidation of the
El Segundo, CA Eaton space products business into the El Monte, CA facility,
manufacturing inefficiencies resulting from temporary shortages of electricity
in California, and significant price increases for electrical power. The
integration of the El Segundo, CA business into the El Monte, CA facility will
be completed in the second quarter of fiscal 2001.

Test

Operating profit of $2.4 million increased $1.7 million or 242.9% in fiscal 2001
over the $.7 million of operating profit in fiscal 2000. The increase is
primarily due to the acquisitions of Lindgren and Holaday in the second half of
fiscal 2000 which contributed approximately $1.3 million and $.3 million,
respectively, of operating profit in the first quarter of fiscal 2001.

Communications

Operating profit of $3.7 million in fiscal 2001 was $1.4 million (60.9%) higher
than the $2.3 million of operating profit in fiscal 2000. The large increase is
the result of significantly higher shipments to PREPA and the Coops as described
above.

Other

Operating loss was ($.6) million in fiscal 2001 and ($.5) million in fiscal
2000. The current period amount consists of $.3 million of operating profit
related to Rantec Power Systems, offset by Corporate operating charges.

INTEREST EXPENSE (INCOME)

Interest expense was $.1 million in fiscal 2001 versus interest income of $.2
million in the first quarter of fiscal 2000 due to the fluctuations in net cash
and net borrowings throughout the periods.

OTHER COSTS AND EXPENSES, NET

Other costs and expenses, net, were $1.9 million in the first quarter of fiscal
2001 compared to $1.6 million in fiscal 2000. The current year amounts are
primarily comprised of goodwill amortization of $.9 million and patent
amortization of $.4 million. The balance relates to miscellaneous costs.
Amortization expense increased approximately $.4 million in the first quarter of
fiscal 2001 compared to the prior period due to the fiscal 2000 acquisitions.

GAIN ON THE SALE OF PROPERTY

The $2.2 million gain in the first quarter of fiscal 2000 related to the sale of
the Riverhead, New York property, used by the Company's former Hazeltine
subsidiary. The property was sold for $2.6 million, consisting of $.5 million in
cash and a $2.1 million interest-bearing, 18-month mortgage note receivable, due
June 2001.

INCOME TAX EXPENSE

The effective income tax rate in the first quarter of fiscal 2001 was 38.7%
compared to 24.3% in the first quarter of fiscal 2000. The prior period
effective tax rate was favorably impacted by the $2.2 million gain on the sale
of the Riverhead property which was sheltered from taxes by capital loss
carryforwards. Excluding the gain on the sale of property, the effective income
tax rate in the first quarter of fiscal 2000 was 36.5%, and included a
settlement related to certain state tax liabilities. Management estimates the
annual effective tax rate for fiscal 2001 to be approximately 39%.

FINANCIAL CONDITION

Working capital increased to $61.0 million at December 31, 2000 from $55.7
million at September 30, 2000. During the first three months of fiscal 2001,
cash and cash equivalents increased by $2.6 million and accounts receivable
decreased by $2.7 million as a result of the timing of sales and collections
throughout the period. Accounts payable and accrued expenses decreased by $3.3
million due to timing of payments throughout the quarter.

Net cash provided by operating activities was $5.4 million in the first three
months of fiscal 2001 compared to net cash used by operating activities of $10.1
million in the same period of fiscal 2000. The cash used by operating activities
in fiscal 2000 was primarily due to payments related to the divestiture of the
former Systems & Electronics, Inc. subsidiary and other working capital
requirements.

Cash flow from operations and borrowings under the bank credit facility are
expected to provide adequate resources to meet the Company's capital
requirements and operational needs for the foreseeable future.

Capital expenditures were $1.5 million in the first three months of fiscal 2001
compared with $1.9 million in the comparable period of fiscal 2000. Major
expenditures in the current period included manufacturing equipment used in the
filtration / fluid flow business.

On February 8, 2001, the Company approved a stock repurchase program. Under
this program, the Company is authorized to purchase up to 1.3 million shares of
its common stock in the open market, subject to market conditions and other
factors, through September 30, 2003.

in interest rates and changes in foreign currency exchange rates. Based on the
current debt structure, the exposure to interest rate risk is not material. The
Company is subject to foreign currency exchange rate risk relating to receipts
from customers and payments to suppliers in foreign currencies. The Company
hedges certain foreign currency commitments by purchasing foreign currency
forward contracts.
