2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS

                The following discussion should be read in conjunction with the
            consolidated financial statements and notes thereto. The years 2001,
            2000 and 1999 represent the fiscal years ended September 30, 2001,
            2000 and 1999, respectively, and are used throughout the document.

Introduction

                ESCO Technologies Inc. (ESCO, the Company) operates principally
            in four business segments: Filtration/Fluid Flow, Test,
            Communications and Other. ESCO develops, manufactures and markets a
            broad range of filtration products used in the separation,
            purification and processing of liquids and gases. The Company's
            engineered filtration products utilize membrane, precision screen
            and other technologies to protect critical processes and equipment
            from contaminants. Major applications include oil production and
            removal of contaminants in fuel, lube and hydraulic systems, various
            health care applications, including blood collection, food and
            beverage processing, potable water, and semiconductor production
            processes. ESCO is a leading supplier of radio frequency (RF)
            shielding and EMC test products. ESCO also supplies shielding to the
            growing Magnetic Resonance Imaging (MRI) market. The Company's
            Communications segment provides a well-proven communications system
            called TWACS(R) to the electric utility industry. The TWACS(R)
            system is currently used primarily for automatic meter reading (AMR)
            and its load management capabilities, and also provides a ready
            conduit into the home for future applications.

                The Company's business segments are comprised of the following
            primary operating entities:

                --Filtration/Fluid Flow: PTI Technologies Inc. (PTI) and
                  Filtertek Inc. (Filtertek),

                --Test: EMC Group consisting of EMC Test Systems, L.P. (ETS) and
                  Lindgren RF Enclosures, Inc. (Lindgren),

                --Communications: Distribution Control Systems, Inc. (DCSI) and
                  Comtrak Technologies, L.L.C. (Comtrak),

                --Other: Rantec Power Systems Inc. (Rantec),

                --Systems & Electronics Inc. (SEI) is included as a divested
                  business in 1999.

                ESCO continues to operate with meaningful growth prospects in
            its primary served markets, and with considerable financial
            flexibility. The Company continues to focus on new products that
            incorporate proprietary design and process technologies. Management
            is committed to delivering shareholder value through internal
            growth, selective acquisitions and share repurchase when warranted.


Highlights of 2001 Operations

                Sales for the year ended September 30, 2001 increased $44.7
           million, or 15% to $344.9 million compared to sales of $300.2 million
           in 2000. Sales growth from acquisitions accounted for approximately
           $28.6 million of the sales increase in 2001. New products introduced
           within the last three years accounted for $70.1 million of 2001
           sales. The Company's Communications segment continued to show strong
           year over year growth as sales increased 38% and approximately $104
           million of new orders were received in 2001.

                Gross profit margin increased to 31.4% in 2001 compared to 30.6%
           in the prior year, reflecting positive results from the Company's
           ongoing cost reduction programs and product mix changes. Operating
           profit margin (defined as net sales, less cost of sales, less SG&A
           expenses) increased to 10.7% of net sales in 2001, compared to 10.0%
           of net sales in 2000. The Company's EBIT margin from operations
           improved by 0.5% in 2001 compared to 2000. EBIT is defined as
           earnings before interest and taxes.

                 In June 2001, the Company acquired Bea Filitri S.p.A. (Bea),
           headquartered in Milan, Italy. Bea is a supplier of filtration
           products to the pharmaceutical, food and beverage, health care, and
           petrochemical markets. Bea's operating results are included within
           the Filtration/Fluid Flow segment, since the date of acquisition.


                                                                              13


2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS


                Fiscal 2001 net earnings as reported, were $30.1 million, or
            $2.35 per share, compared to $16.8 million, or $1.33 per share, in
            2000. During 2001, the Company's results were favorably impacted by
            an income tax adjustment of $12.7 million, or $0.99 per share,
            related primarily to the elimination of the Company's net deferred
            tax valuation allowance. Excluding this favorable income tax
            adjustment, 2001 net earnings from operations were $17.4 million, or
            $1.36 per share, compared to 2000 net earnings from operations of
            $14.1 million, or $1.11 per share. 2000 net earnings from operations
            exclude the after-tax gains from the sale of the Riverhead, NY and
            Calabasas, CA properties in 2000, which were approximately $2.7
            million, or $0.22 per share.


Recap of 2000 Performance

                The Company successfully completed three acquisitions during
            2000: Lindgren, Holaday Industries, Inc. (Holaday), and the Eaton
            space products business (Eaton), formerly located in El Segundo, CA.
            The Lindgren and Holaday operating results are included within the
            Test segment and the Eaton results are included within the
            Filtration/Fluid Flow segment since the date of the respective
            acquisitions.

                Fiscal 2000 sales increased $56.9 million, or 23% to $300.2
            million over 1999 "adjusted" sales of $243.3 million, mainly due to
            new product introductions and contributions from the 2000
            acquisitions. Fiscal 2000 acquisitions contributed $25.7 million to
            sales in 2000. Operating profit, as defined above, increased $16.5
            million to $30.1 million in 2000 over 1999 "adjusted" operating
            profit of $13.6 million.

                Fiscal 2000's net earnings, as reported, were $1.33 per share.
            In 2000, the Company sold properties in Riverhead, NY and Calabasas,
            CA, thereby, converting into cash properties retained after
            divestitures. Excluding the gains on the sale of these properties,
            2000 net earnings from operations were $1.11 per share compared to
            1999 "adjusted" net earnings of $0.61 per share. Refer to the table
            on page 21 of Management's Discussion and Analysis for the
            definition and reconciliation of "adjusted" net income in 1999.


1999 Strategic Actions

                In conjunction with the divestiture of SEI, the Company took a
            number of actions at September 30, 1999 to further sharpen its focus
            on its primary served markets. Other actions included abandoning the
            active pursuit of certain business areas, exiting non-core,
            underperforming businesses, and restructuring the corporate overhead
            of the Company.


Results of Operations

            NET SALES

                Net sales of $344.9 million in 2001 increased $44.7 million
            (14.9%) from net sales of $300.2 million in 2000. Filtration/Fluid
            Flow, Test and Communications segments all had increased sales in
            2001. Sales growth from acquisitions accounted for approximately
            $28.6 million of the sales increase, with the balance coming from
            organic growth. New products introduced within the last three years
            accounted for $70.1 million of 2001 sales.

                Net sales of $300.2 million in 2000 decreased $115.9 million
            (27.9%) from reported net sales of $416.1 million in 1999 due to the
            divestiture of SEI. The 1999 amount included SEI sales of $172.8
            million. Excluding SEI sales from the 1999 results, 2000 net sales
            increased $56.9 million (23.4%) over 1999 "adjusted" net sales of
            $243.3 million. Acquisitions contributed $25.7 million to sales in
            2000.

2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS

            Filtration/Fluid Flow

                Net sales of $188.2 million in 2001 were $6.5 million (3.6%)
            higher than net sales of $181.7 million in 2000. Net sales increased
            in the health care and aerospace markets, offset by declines in the
            automotive and semiconductor markets. The current year acquisition
            of Bea contributed approximately $2.0 million to the increase in
            sales. The incremental sales contribution from the fiscal 2000
            acquisition of the Eaton space products business was approximately
            $3.3 million in 2001.

                Net sales of $181.7 million in 2000 increased $12.8 million
            (7.6%) from net sales of $168.9 million in 1999, primarily due to
            new product introductions and increases in microfiltration sales.
            The acquisition of the Eaton space products business in fiscal 2000
            contributed approximately $3.4 million of the increase in sales.
            Test

                Net sales increased $22.5 million (35.6%) to $85.5 million in
            2001 compared to net sales of $63.0 million in 2000. Fiscal 2001
            reflected the full year contributions from Lindgren and Holaday.
            Sales of the Company's Magnetic Resonance Imaging (MRI) products
            increased in 2001 by more than 15%, attributable to the growing
            health care market. This was partially offset by a decrease in the
            sale of large EMC test chambers to electronics and
            telecommunications customers as a result of the softening of these
            markets. The General Motors contract contributed approximately $4.6
            million, $13.2 million and $3.1 million to sales in 2001, 2000 and
            1999, respectively.

                Net sales of $63.0 million in 2000 increased $28.1 million
            (80.5%) over the $34.9 million in net sales recorded in 1999. The
            increase in 2000 over 1999 is primarily due to acquisitions, which
            contributed $22.1 million. The remaining increase in 2000 over 1999
            is primarily the result of additional EMC test chamber sales.

            Communications

                Net sales of $59.1 million in 2001 were $16.4 million (38.3%)
            higher than net sales of $42.7 million in 2000. The increase in 2001
            over 2000 is primarily the result of increased shipments to electric
            utility Cooperatives (Co-ops), together with continued shipments to
            other existing customers, such as Puerto Rico Electric Power
            Authority (PREPA), Wisconsin Public Service Corporation (WPS), and
            Florida Power & Light (FPL). The Company recorded approximately $104
            million in new orders for its two-way automatic communications
            systems and load control transponders during 2001.

                The 2000 net sales increased $16.9 million over the $25.8
            million in net sales recorded in 1999. The increase in 2000 over
            1999, primarily is the result of increased shipments to PREPA, WPS
            and the Co-ops.

            Other

                Net sales were $12.2 million in 2001, $12.8 million in 2000 and
            $13.7 million in 1999. The decrease in net sales is due to the sale
            of the Rantec microwave antenna business in February 2000, which
            contributed approximately $2.1 million to sales in fiscal 2000 prior
            to its divestiture and contributed $3.5 million to sales in 1999.
            Excluding the microwave antenna business from the 2000 results, net
            sales increased $1.5 million or 14% in 2001.

            ORDERS AND BACKLOG

                Firm order backlog was $180.1 million at September 30, 2001,
            compared to $145.4 million at September 30, 2000. New orders
            totaling $379.6 million were received in 2001, compared with $288.7
            million in 2000, reflecting a 31.5% increase. Approximately $186
            million of new orders in 2001 related to Filtration/Fluid Flow
            products, approximately $79 million related to Test products, and
            approximately $104 million related to Communications products
            (automatic meter reading and load control products).

            GROSS PROFIT

                 The Company computes gross profit as: net sales less cost of
            sales. The gross profit margin is the gross profit divided by net
            sales, expressed as a percentage.

                 The gross profit margin was 31.4%, 30.6% and 22.7% in 2001,
            2000 and 1999, respectively. The "adjusted" gross profit margin for
            1999 was 27.6%. The increase in 2001 compared to 2000 is due
            primarily to a favorable sales mix and the results of the Company's
            ongoing cost improvement initiatives. The increase in 2000 compared
            to the reported 1999 results is due primarily to the lower margins
            in 1999 related to the defense businesses. Gross profit margin
            increased in 2000 compared to "adjusted" 1999 results due to
            operational improvements in all four operating segments, including
            favorable changes in sales mix and product pricing as well as
            successful cost containment programs.

2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS


            SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

                Selling, general and administrative expenses (SG&A) for 2001
            were $71.5 million, or 20.7% of net sales, compared with $61.8
            million, or 20.6% of net sales for 2000. The increase in SG&A
            spending in 2001 is mainly due to the 2000 acquisitions being
            included for the entire fiscal year 2001, as well as additional
            investments in research and development, engineering, and marketing
            within the Filtration/Fluid Flow and Communications segments.

                SG&A expenses in 2000 were $61.8 million, or 20.6% of net sales,
            compared with $74.4 million, or 17.9% of net sales for 1999.
            "Adjusted" SG&A expenses were $53.6 million, or 22.0% of net sales
            in 1999. The 2000 SG&A expenses included $4.9 million of additional
            expenses related to the 2000 acquisitions. The percentage decrease
            from "adjusted" 1999 SG&A expenses is the result of favorable
            leverage achieved on the higher sales volume.

            OPERATING PROFIT

                The Company evaluates the performance of its operating segments
            based on operating profit, which the Company defines as net sales,
            less cost of sales, and less SG&A expenses. Operating profit, as
            defined by the Company, excludes certain costs which are included in
            Other costs and expenses, net, in the Consolidated Statements of
            Operations, and which would be included in the determination of
            operating income as defined within generally accepted accounting
            principles. These items are discussed in the respective segment
            information below.

                Operating profit of $36.8 million (10.7% of net sales) in 2001
            increased $6.7 million (22.5%) from $30.1 million (10% of net sales)
            in 2000. In 2001, operating profit dollars increased in all
            segments.

                Operating profit of $30.1 million (10% of net sales) in 2000
            increased $15.2 million (102%) from $14.9 million in 1999. The 1999
            operating profit amount included $10.4 million related to SEI.
            Fiscal 2000 operating profit increased $16.5 million over prior year
            "adjusted" operating profit of $13.6 million.
            Filtration/Fluid Flow

                Operating profit of $16.8 million (8.9% of net sales) in 2001
            increased slightly over operating profit of $16.6 million (9.1% of
            net sales) in 2000. The current year was impacted by non-recurring
            costs related to the consolidation of the Eaton space products
            business into existing Company owned facilities and increases in
            other facility operating costs. In addition, during 2001, the
            Company made significant investments in new product development and
            market expansion opportunities, primarily in microfiltration.

                Operating profit of $16.6 million (9.1% of net sales) in 2000
            was $4.7 million (39.5%) higher than operating profit of $11.9
            million (7.0% of net sales) in 1999. The increase was primarily the
            result of new product introductions and increases in microfiltration
            profitability. Increased shipments of disposable water filter
            cartridges also contributed to the growth in profitability in 2000.
            Test

                Operating profit increased approximately $2.4 million to $9.3
            million (10.9% of net sales) in 2001 compared to $6.9 million (11.0%
            of net sales) in 2000. The increase in 2001 is mainly due to the
            full year contributions from the Lindgren and Holaday acquisitions,
            which occurred in the second half of fiscal 2000, offset by a
            smaller revenue contribution from the General Motors contract which
            is nearing completion. Operating profit of $6.9 million (11.0% of
            net sales) in 2000 was $2.9 million (72.5%) higher than operating
            profit of $4.0 million (11.5% of net sales) in 1999. The increase in
            2000 over 1999, was primarily the result of contributions from the
            General Motors contract. Fiscal 2000 was also favorably impacted by
            the mid-year acquisitions mentioned above.

            Communications

                Operating profit of $12.6 million (21.4% of net sales) in 2001
            was $3.7 million, or 41.6% higher than operating profit of $8.9
            million (20.8% of net sales) in 2000. Operating profit of $8.9
            million (20.8% of net sales) in 2000 was $9.3 million higher than
            operating profit of ($0.4) million in 1999. The increase in
            operating profit in 2001 versus 2000, as well as 2000 versus 1999,
            in both dollars and as a percentage of net sales is due to increased
            shipments of automatic meter reading (AMR) equipment at DCSI. The
            Company is increasing its engineering and new product development
            expenditures in the Communications segment in order to continue its
            growth in the


16

2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS


            AMR markets. The 1999 operating profit was impacted by certain
            nonrecurring charges at Comtrak, discussed on page 22 of
            Management's Discussion and Analysis. Other

                Operating profit was $1.4 million, ($0.3) million and ($8.8)
            million in 2001, 2000 and 1999, respectively. The increase in
            operating profit in 2001 over 2000, and in 2000 over 1999, is mainly
            related to the improved operations of Rantec's Power Systems
            business and the February 2000 sale of the microwave antenna
            business. The 1999 results were impacted by the nonrecurring charges
            related to the microwave antenna business, discussed on page 22.

            INTEREST EXPENSE

                Interest expense decreased to $0.1 million in 2001 from $0.4
            million in 2000, primarily as a result of lower outstanding average
            borrowings throughout 2001. The timing of operating cash flows
            throughout 2001 also decreased the average outstanding borrowings.

                Interest expense decreased to $0.4 million in 2000 from $6.5
            million in 1999, primarily as a result of lower outstanding average
            borrowings throughout 2000. With the exception of $1 million of
            foreign debt, all outstanding debt from fiscal 1999 was repaid in
            October 1999 from the proceeds of the sale of SEI.

            OTHER COSTS AND EXPENSES, NET

                Other costs and expenses, net, were $9.4 million, $8.0 million
            and $4.9 million in 2001, 2000 and 1999, respectively. The 2001 net
            amount includes: Goodwill amortization of $3.4 million; patent and
            other intangible amortization of $1.4 million; approximately $2.1
            million of net costs related to the consolidation of PTI's
            filtration businesses into new facilities in Oxnard, CA and the
            consolidation of the Stockton, CA manufacturing facility into the
            Huntley, IL facility; and other miscellaneous costs.

                Other costs and expenses, net, in 2000, of $8.0 million
            consisted of the following items: Goodwill amortization of $2.6
            million; patent and other intangible amortization of $1.3 million;
            approximately $2.0 million of net costs related to the
            Filtration/Fluid Flow segment, including the consolidation of PTI's
            filtration businesses into new facilities in Oxnard, CA, expenses
            related to the planned upgrade of production equipment to improve
            manufacturing efficiency at Filtertek, and costs related to the
            microfiltration business; approximately $1.0 million of net costs
            related to the Test segment primarily related to the write-off of an
            investment in a third party EMC related start-up company which filed
            bankruptcy in 2000; and other miscellaneous costs.

            GAIN ON SALE OF PROPERTIES

                The gain on the sale of properties in fiscal 2000 represents
            $2.2 million from the sale of the Riverhead, NY property and $0.8
            million from the sale of the Calabasas, CA property. These
            properties were related to previously divested companies.

            INCOME TAX (BENEFIT) EXPENSE

                Income tax benefit of ($2.8) million for 2001 reflects current
            tax expense of $0.4 million, deferred tax benefit of ($5.7) million,
            and foreign, state and local tax expense of $2.4 million. Income tax
            expense of $7.9 million for 2000 reflects current tax expense of
            $0.3 million, deferred tax expense of $6.3 million, and foreign,
            state and local tax expense of $1.4 million.

                 Based on the Company's historical pretax income, together with
            the projection of future taxable income, Management believes it is
            more likely than not that the Company will realize the benefits of
            the net deferred tax asset existing at September 30, 2001. In order
            to realize the aforementioned net deferred tax asset, the Company
            will need to generate future taxable income of approximately $154
            million, of which $130 million is required to be realized prior to
            the expiration of the net operating loss (NOL) carryforward, of
            which $8 million will expire in 2006; $6 million will expire in
            2007; $23 million will expire in 2009; $38 million will expire in
            2010; $4 million will expire in 2011; $11 million will expire in
            2018; and $40 million will expire in 2019. The net operating loss
            carryforward will be available to reduce future Federal income tax
            cash payments.

                In 2001, as the result of certain residual tax effects related
            to the 2000 sale of the property in Calabasas, CA, the Company
            utilized approximately $2 million of the remaining $33 million
            capital loss carryforward available from the sale of its Hazeltine
            subsidiary in 1996. The remaining capital loss carryforward of
            approximately $31 million expired on September 30, 2001.


                                                                              17


2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS


                The valuation reserve in the amount of $10.8 million maintained
           for the deferred tax asset related to the capital loss carryforward
           was eliminated due to the expiration of the capital loss
           carryforward. Additionally, in 2001 the Company eliminated its
           remaining net deferred tax valuation allowance of $12.7 million,
           which was the allowance representing the amount of the deferred tax
           asset associated with temporary differences and NOLs which Management
           believed would likely not be realized due to limitations on future
           use.

                The effective tax rate in 2001 was (10.4%), compared with 32.0%
            in 2000 primarily due to the favorable impact of the elimination of
            the net deferred tax valuation allowance. On an operational basis,
            Management estimates the 2001 effective tax rate would have been
            36.1%, excluding the net favorable income tax adjustment of $12.7
            million, previously described. An analysis of the effective tax
            rates for 2001, 2000 and 1999 is included in the notes to the
            consolidated financial statements.

            CHANGE IN ACCOUNTING PRINCIPLE - 1999

                The Company adopted the provisions of Statement of Position
            (SOP) 98-5, "Reporting on the Costs of Start-up Activities" in the
            first quarter of 1999 which resulted in a non-cash, after-tax charge
            of approximately $25 million, which was recognized as a cumulative
            effect of an accounting change. The charge related to precontract,
            start-up and organization costs incurred in anticipation of specific
            future contract awards which were based on specific customer
            identified requirements.


Capital Resources & Liquidity

                Working capital increased to $87.4 million at September 30, 2001
            from $62.8 million at September 30, 2000. During 2001, cash and cash
            equivalents increased by $8.9 million. Inventories increased $3.7
            million primarily due to the 2001 acquisition of Bea. Other current
            assets increased by $10.7 million primarily due to an increase in
            the current portion of deferred tax assets.

                Net cash provided by operating activities was $33.0 million in
            2001 compared to $20.0 million in 2000. The increase in 2001 is
            primarily due to the Company's additional earnings and improved
            working capital resulting from ongoing asset management initiatives.

                Net cash provided by operating activities was $20.0 million in
            2000 compared to $25.9 million in 1999. Net cash provided by
            operating activities in 2000 increased $5.4 million from the 1999
            adjusted amount of $14.6 million, which excludes $11.3 million
            related to SEI.

                Capital expenditures of $11.9 million, $10.4 million and $8.3
            million, in 2001, 2000 and 1999, respectively, primarily included
            manufacturing equipment. Capital expenditures related to SEI were
            $1.1 million in 1999. There were no commitments outstanding that
            were considered material for capital expenditures at September 30,
            2001.

                At September 30, 2001, the Company had available a net operating
            loss (NOL) carryforward for tax purposes of approximately $130
            million. This NOL will expire beginning in year 2006 and ending in
            year 2019, and will be available to reduce future Federal income tax
            cash payments.

            ACQUISITIONS/DIVESTITURES

                On June 8, 2001, the Company acquired all of the outstanding
            common stock of Bea Filtri S.p.A. (Bea) for approximately $13.5
            million in cash and debt. Bea, headquartered in Milan, Italy, is a
            supplier of filtration products to the pharmaceutical, food and
            beverage, healthcare, and petrochemical markets. Bea's assets and
            liabilities, and related operating results, since the date of
            acquisition, are included within the Company's Filtration/Fluid Flow
            segment.

                On June 2, 2000, the Company purchased Holaday Industries, Inc.
            (Holaday) for approximately $4 million in cash. Holaday,
            headquartered in Eden Prairie, MN, is a leading supplier of
            specialty measurement probes to the EMC test, health and safety, and
            microwave markets. The operating results for Holaday, since the date
            of acquisition, are included within the Company's Test segment.

                On April 9, 2000, the Company acquired all of the outstanding
            common stock of Lindgren RF Enclosures, Inc. (formerly known as The
            Curran Company) and Lindgren, Inc. (doing business through its
            subsidiary, Rayproof Ltd.) (collectively Lindgren) for approximately
            $22 million in cash plus additional consideration based upon the
            future operating performance of Lindgren. Lindgren is a leading
            supplier of radio frequency (RF) shielding products and


18


2001 ESCO TECHNOLOGIES ANNUAL REPORT
MANAGEMENT'S DISCUSSION AND ANALYSIS


            components used by manufacturers of medical equipment,
            communications systems and electronic products. The operating
            results for Lindgren, since the date of acquisition, are included
            within the Company's Test segment.

                On March 31, 2000, the Company acquired the Eaton space products
            business (Eaton), formerly located in El Segundo, CA, for
            approximately $6 million in cash. Eaton manufactures specialty
            valves and other fluid flow components for satellite launch vehicles
            and aircraft applications and has been integrated into the Company's
            Filtration/Fluid Flow segment, since the date of acquisition.

                All of the Company's acquisitions have been accounted for using
            the purchase method of accounting. The goodwill recorded as a result
            of the above transactions is being amortized over 20 years, until
            the adoption of SFAS 142.

                In February 2000, the Company completed the sale of its
            microwave antenna product line, which had historically operated as
            part of Rantec Microwave & Electronics, Inc. The Company transferred
            the contract order backlog and operating assets of the microwave
            antenna business for $2.1 million in cash, and in September 2000,
            sold the related land and buildings in Calabasas, CA for
            approximately $6 million.

                In December 1999, the Company sold the Riverhead, NY property,
            used by the Company's former Hazeltine subsidiary for approximately
            $2.6 million.

                On September 30, 1999, the Company sold SEI to Engineered
            Support Systems, Inc. for $85 million in cash, less working capital
            adjustments.

            BANK CREDIT FACILITY

                On April 11, 2000, the Company entered into a $75 million
            revolving credit facility, with the option to increase it to $100
            million through April 11, 2002. The credit facility was amended on
            February 28, 2001 to allow for borrowings in foreign currencies. The
            credit facility is available for direct borrowings and/or the
            issuance of letters of credit. The maturity of the credit facility
            is April 11, 2005, and is provided by a group of five banks, led by
            Bank of America. At September 30, 2001, the Company had
            approximately $61.7 million available to borrow under the credit
            facility as well as $14.5 million of cash on hand.

                The credit facility requires, as determined by certain financial
            ratios, a commitment fee ranging from 20-30 basis points per annum
            on the unused portion. The terms of the facility provide that
            interest on borrowings may be calculated at a spread over the London
            Interbank Offered Rate (LIBOR) or based on the prime rate, at the
            Company's election. Substantially all of the assets of the Company
            are pledged under the credit facility. The financial covenants of
            the credit facility include limitations on leverage and minimum
            consolidated EBITDA. As of September 30, 2001, the Company is in
            compliance with all bank covenants.

                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.

            SHARE REPURCHASE

                In February 2001, the Company authorized an open market
            repurchase program of up to 1.3 million shares, which is subject to
            market conditions and other factors and covers the period ending
            September 29, 2003. Approximately 77,000, 516,000 and 177,000 shares
            were repurchased in 2001, 2000 and 1999, respectively. In June 2000,
            the Company initiated an odd lot share repurchase program which
            extended through September 2000 whereby the Company repurchased
            approximately 25,000 shares, which are included in the 516,000 of
            shares repurchased in 2000, above.

            OTHER

                Management believes that, for the periods presented, inflation
            has not had a material effect on the Company's results of
            operations.

                The Company is currently involved in various stages of
            investigation and remediation relating to environmental matters.
            Based on current information available, Management does not believe
            the aggregate costs involved in the resolution of these matters will
            have a material adverse effect on the Company's operating results,
            capital expenditures or competitive position.


                                                                              19

            MARKET RISK EXPOSURE

                Market risks relating to the Company's operations result
            primarily from changes in interest rates and changes in foreign
            currency exchange rates. The Company has interest rate exposure
            relating to floating rate lease obligations and, accordingly, during
            2001, entered into interest rate swaps totaling approximately $23
            million to mitigate this exposure. In addition, the Company has
            interest rate exposure relating to floating rate obligations
            denominated in EURO dollars, therefore, in September 2001, the
            Company entered into an interest rate swap of approximately $4
            million to mitigate this exposure. These swaps are accounted for as
            cash flow hedges under the provisions of SFAS 133, "Accounting for
            Derivative Instruments and Hedging Activities" as of and for the
            year ended September 30, 2001.

                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.

New Accounting Pronouncements

                In July 2001, the Financial Accounting Standards Board issued
            SFAS 141, "Business Combinations", and SFAS 142, "Goodwill and Other
            Intangible Assets". SFAS 141 requires that the purchase method of
            accounting be used for all business combinations initiated or
            completed after June 30, 2001. SFAS 141 also specifies criteria
            intangible assets acquired in a purchase method business combination
            must meet to be recognized and reported apart from goodwill. SFAS
            142 requires that goodwill and intangible assets with indefinite
            useful lives no longer be amortized, but instead tested for
            impairment at least annually in accordance with the provisions of
            SFAS 142. SFAS 142 also requires that intangible assets with
            definite useful lives be amortized over their respective estimated
            useful lives to their estimated residual values, and reviewed for
            impairment in accordance with SFAS 121, "Accounting for the
            Impairment of Long-Lived Assets and for Long-Lived Assets to Be
            Disposed Of".

                The Company is required to adopt the provisions of SFAS 141
            immediately. Management expects to adopt the provisions of SFAS 142
            effective October 1, 2001, the beginning of the Company's fiscal
            year 2002.

                SFAS 141 will require that upon adoption of SFAS 142, the
            Company evaluate its existing intangible assets and goodwill, and
            make any necessary reclassifications in order to conform with the
            new criteria in SFAS 141. Upon adoption of SFAS 142, the Company
            plans to reassess the useful lives and residual values of all
            recorded intangible assets, other than goodwill, and make any
            necessary amortization period adjustments by December 31, 2001. In
            addition, to the extent an intangible asset is identified as having
            an indefinite useful life, the Company will be required to test the
            intangible asset for impairment in accordance with the provisions of
            SFAS 142 by December 31, 2001. Any impairment loss will be measured
            as of the date of adoption and recognized as the cumulative effect
            of a change in accounting principle. Upon adoption of SFAS 141 and
            SFAS 142, the Company does not anticipate a significant impact to
            the carrying value of the Company's goodwill.

MANAGEMENT'S DISCUSSION AND ANALYSIS

1999 Strategic Actions

            RECONCILIATION OF ADJUSTED NET INCOME - 1999

                  In conjunction with the divestiture of SEI, the Company took a
            number of actions at September 30, 1999 to further sharpen its focus
            on its primary served markets. Other actions included abandoning the
            active pursuit of certain business areas, exiting non-core,
            underperforming businesses, and restructuring the corporate overhead
            of the Company.

                  The following table is not intended to present 1999 net
            earnings as defined within generally accepted accounting principles
            (GAAP), and is presented for informational purposes only.

                  The table provides a reconciliation between the 1999 reported
            results of operations and what Management believes the 1999
            operating results may have been after removing certain nonrecurring
            items and assuming that all of the actions taken during 1999 to
            reorient the business were complete at the beginning of the period.
            Management believes the estimated 1999 adjusted operating results
            provide a meaningful presentation for purposes of comparing ESCO's
            subsequent financial performance.

MANAGEMENT'S DISCUSSION AND ANALYSIS


            OTHER CHARGES RELATED TO COST OF SALES, RESTRUCTURING CHARGES AND
            GAIN ON SALE OF SEI - 1999

                The Company recognized certain nonrecurring items in the 1999
            fourth quarter results of operations which resulted in $3.9 million
            of other charges related to cost of sales and $5.1 million of
            restructuring charges. In addition, in 1999, the Company recorded a
            gain on the sale of SEI of $59.9 million.

                The 1999 other charges related to cost of sales represent the
            write-off of inventory related to the abandonment of High Pressure
            Air Reducing Quiet Manifolds for surface ships ($2.2 million) and
            the Vehicle Location Systems ($.6 million) business. Additionally,
            the Company wrote down the Rantec microwave antenna product line
            inventory ($1.1 million) to net realizable value. The Rantec
            microwave business was sold in February 2000.

                The 1999 restructuring charges were comprised of the following:
            costs related to exiting the microwave antenna business area ($1.1
            million); a write-off of the license agreement ($1.8 million)
            related to the abandonment of the Vehicle Location System business;
            and certain personnel separation costs ($2.2 million).

                The gain on the sale of SEI of $59.9 million is calculated as:
            the gross proceeds of $85 million; less SEI's net book value of
            $30.6 million; less working capital adjustments of $4.0 million;
            less transaction related expenses of $4.9 million; plus the $14.4
            million curtailment gain related to pension and retiree medical
            liabilities transferred to the buyer.

                The other charges related to cost of sales noted above are
            included in the calculation of 1999 gross profit discussed above.

Forward-Looking Information

                The statements contained in the Chairman's Letter to
            Shareholders (pgs. 2-5), the business summaries (pgs. 6-11), and
            Management's Discussion and Analysis that are not strictly

            the future may differ materially from those projected in the
            forward-looking statements due to risks and uncertainties that exist
            in the Company's operations and business environment including, but
            not limited to: further weakening of economic conditions in served
            markets; changes in customer demands or customer insolvencies;
            electricity shortages; competition; intellectual property matters;
            consolidation of internal operations; integration of recently
            acquired businesses; delivery delays or defaults by customers;
            performance issues with key suppliers and subcontractors; collective
            bargaining labor disputes; and the Company's successful execution of
            internal operating plans.

2001 ESCO TECHNOLOGIES ANNUAL REPORT
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.    Summary of significant accounting policies

            (a) PRINCIPLES OF CONSOLIDATION

                The consolidated financial statements include the accounts of
            ESCO Technologies Inc. (ESCO) and its wholly owned subsidiaries (the
            Company). All significant intercompany transactions and accounts
            have been eliminated in consolidation. Certain prior year amounts
            have been reclassified to conform with the 2001 presentation.
            Effective July 10, 2000, the Company changed its name from ESCO
            Electronics Corporation to ESCO Technologies Inc.

            (b) BASIS OF PRESENTATION

                Effective September 30, 1993, the Company implemented an
            accounting readjustment in accordance with the accounting provisions
            applicable to a "quasi-reorganization" which restated assets and
            liabilities to fair values and eliminated the deficit in retained
            earnings.

                Fair values of the Company's financial instruments are estimated
            by reference to quoted prices from market sources and financial
            institutions, as well as other valuation techniques. The estimated
            fair value of each class of financial instruments approximated the
            related carrying value at September 30, 2001 and 2000.

            (c) NATURE OF OPERATIONS

                The Company is a leading supplier of engineered filtration
            products to the process, health care and transportation markets
            worldwide. The Company's filtration products include depth filters,
            membrane based microfiltration products and precision screen
            filters. The balance of the Company's sales is derived primarily
            from radio frequency (RF) shielding and EMC test products and
            special purpose communication systems, where the Company is well
            positioned in niche markets based on proprietary products.

                The Company operates in four principal industry segments:
            Filtration/Fluid Flow, Test, Communications and Other.

            (d) USE OF ESTIMATES

                The preparation of financial statements in conformity with
            accounting principles generally accepted in the United States of
            America requires management to make estimates and assumptions,
            including estimates of anticipated contract costs and revenues
            utilized in the earnings process, that affect the reported amounts
            of assets and liabilities and disclosure of contingent assets and
            liabilities at the date of the financial statements and the reported
            amounts of revenues and expenses during the reporting period. Actual
            results could differ from those estimates.

            (e) REVENUE RECOGNITION

                Revenue is recognized on commercial sales when products are
            shipped or when services are performed. Revenue on production
            contracts is recorded when specific contract terms are fulfilled,
            usually by delivery or acceptance (the units of production or
            delivery methods). Revenues from cost reimbursement contracts are
            recorded as costs are incurred, plus fees earned. Revenue under
            long-term contracts for which units of production or delivery are
            inappropriate measures of performance is recognized on the
            percentage-of-completion method based upon incurred costs compared
            to total estimated costs under the contract, or are based upon
            equivalent units produced. Revenue under engineering contracts is
            generally recognized as milestones are attained.

            (f) CASH AND CASH EQUIVALENTS

                Cash equivalents include temporary investments that are readily
            convertible into cash, such as EURO dollars, commercial paper and
            treasury bills with original maturities of three months or less.

            (g) COSTS AND ESTIMATED EARNINGS ON LONG-TERM CONTRACTS

                Costs and estimated earnings on long-term contracts represent
            unbilled revenues, including accrued profits and retention on
            long-term contracts accounted for under the percentage-of-completion
            method, net of progress billings.

            (h) INVENTORIES

                Inventories are carried at the lower of cost (first-in,
            first-out) or market. Inventories under long-term contracts reflect
            accumulated production costs, factory overhead, initial tooling and
            other related costs less the portion of such costs charged to cost
            of sales and any progress payments received. In accordance with
            industry practice, costs incurred on contracts in progress include
            amounts relating to programs having production cycles longer than
            one year, and a portion thereof will not be realized within one
            year.

2001 ESCO TECHNOLOGIES ANNUAL REPORT
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


            (i) PROPERTY, PLANT AND EQUIPMENT

                Property, plant and equipment are recorded at cost. Depreciation
            and amortization are computed primarily on a straight-line basis
            over the estimated useful lives of the assets: buildings, 10-40
            years; machinery and equipment, 5-10 years; and office furniture and
            equipment, 5-10 years. Leasehold improvements are amortized over the
            remaining term of the applicable lease or their estimated useful
            lives, whichever is shorter.

           (j) EXCESS OF COST OVER NET ASSETS OF PURCHASED BUSINESSES

                Assets and liabilities related to business combinations
            accounted for as purchase transactions are recorded at their
            respective fair values. Excess of cost over the fair value of net
            assets purchased (goodwill) is amortized on a straight-line basis
            over the periods estimated to be benefited. The excess of cost over
            the fair value of net assets is primarily being amortized over a
            period not exceeding 30 years. The Company assesses the
            recoverability of this intangible asset by determining whether the
            amortization of the asset balance over its remaining life can be
            recovered through undiscounted future operating cash flows. See
            further discussion below in "New Accounting Standards."

            (k) IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE
                DISPOSED OF

                Recoverability of assets to be held and used is measured by a
            comparison of the carrying amount of an asset to future net cash
            flows expected to be generated by the asset. If such assets are
            considered to be impaired, the impairment to be recognized is
            measured by the amount by which the carrying amount of the assets
            exceeds the fair value of the assets. Assets to be disposed of are
            reported at the lower of the carrying amount or fair value less
            costs to dispose.

            (l) INCOME TAXES

                Income taxes are accounted for under the asset and liability
            method. Deferred tax assets and liabilities are recognized for the
            future tax consequences attributable to differences between the
            financial statement carrying amounts of existing assets and
            liabilities and their respective tax bases. Deferred tax assets and
            liabilities are measured using enacted tax rates expected to apply
            to taxable income in the years in which those temporary differences
            are expected to be recovered or settled. Deferred tax assets may be
            reduced by a valuation allowance if it is more likely than not that
            some portion or all of the deferred tax assets will not be realized.
            The effect on deferred tax assets and liabilities of a change in tax
            rates is recognized in income in the period that includes the
            enactment date.

            (m) RESEARCH AND DEVELOPMENT COSTS

                Company-sponsored research and development costs include
            research and development and bid and proposal efforts related to the
            Company's products and services. Company-sponsored product
            development costs are charged to expense when incurred.
            Customer-sponsored research and development costs incurred pursuant
            to contracts are accounted for similar to other program costs.

            (n) FOREIGN CURRENCY TRANSLATION

                The financial statements of the Company's foreign operations are
            translated into U.S. dollars in accordance with Statement of
            Financial Accounting Standards (SFAS) No. 52 "Foreign Currency
            Translation" (SFAS 52). The resulting translation adjustments are
            recorded as a separate component of accumulated other comprehensive
            income.

            (o) 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.


                                                                              29

</Table>

                Options to purchase 12,500 shares (at per share prices of $25.18
            - $27.28), 95,500 shares (at per share prices of $15.72 - $19.22)
            and 176,000 shares (at per share prices of $11.44 - $19.22) were
            outstanding during the years ended September 30, 2001, 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 2011. Approximately
            181,000, zero and 190,000 performance shares were outstanding but
            unearned at September 30, 2001, 2000 and 1999, respectively, and
            therefore, were not included in the respective years' computations
            of diluted EPS.

            (p) STOCK-BASED COMPENSATION

                The Company measures its compensation cost of equity instruments
            issued under employee compensation plans under the provisions of
            Accounting Principles Board Opinion No. 25 (APB 25), "Accounting for
            Stock Issued to Employees," and related Interpretations.

            (q) COMPREHENSIVE INCOME (LOSS)

                SFAS 130, "Reporting Comprehensive Income" requires the Company
            to report separately the translation adjustments of SFAS 52 defined
            above, changes to the minimum pension liability, and changes in fair
            value of the Company's interest rate swaps designated as a cash flow
            hedge, as components of comprehensive income or loss. Management has
            chosen to disclose the requirements of this Statement within the
            Consolidated Statements of Shareholders' Equity.

            (r) ACCOUNTING CHANGE - 1999

                During the first quarter of 1999, the Company adopted Statement
            of Position (SOP) 98-5, "Reporting on the Costs of Start-up
            Activities." Precontract costs were incurred by the Company and
            capitalized under the previous guidance provided by SOP 81-1,
            "Accounting for Performance of Construction-type Contracts." As a
            result of adopting SOP 98-5 in 1999, the Company expensed these
            costs which were recognized as a cumulative effect of an accounting
            change. The effect of this accounting change was recognized in the
            1999 Consolidated Statement of Operations.

            (s) ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

                SFAS 133, "Accounting for Derivative Instruments and Hedging
            Activities" as amended by SFAS 137 and 138 (SFAS 133) requires that
            all derivative instruments be recorded on the balance sheet at their
            fair value. The accounting treatment of changes in fair value is
            dependent upon whether or not a derivative instrument is designated
            as a hedge and if so, the type of hedge. For derivatives designated
            as a fair value hedge, the changes in fair value are recognized in
            other comprehensive income until the hedged item is settled and
            recognized in earnings. The Company has interest rate exposure
            relating to floating rate lease obligations and, accordingly, during
            2001, entered into interest rate swaps totaling approximately $23
            million to mitigate this exposure. In addition, the Company has
            interest rate exposure relating to floating rate obligations
            denominated in EURO dollars, therefore, in September 2001, the
            Company entered into an interest rate swap of approximately $4
            million to mitigate this exposure. These interest rate swaps are
            accounted for as cash flow hedges under the provisions of SFAS 133
            as of and for the year ended September 30, 2001. At September 30,
            2001, other comprehensive income included an after-tax decline in
            fair value of approximately $0.9 million.

            (t) NEW ACCOUNTING STANDARDS

                In July 2001, the Financial Accounting Standards Board issued
            SFAS 141, "Business Combinations", and SFAS 142, "Goodwill and Other
            Intangible Assets". SFAS 141 requires that the purchase method of
            accounting be used for all business combinations initiated or
            completed after June 30, 2001. SFAS 141 also specifies criteria
            intangible assets acquired in a purchase method business combination
            must meet to be recognized and reported apart from goodwill. SFAS
            142 requires that goodwill and intangible assets with indefinite
            useful lives no longer be amortized, but instead tested for
            impairment at least annually in accordance with the provisions of
            SFAS 142. SFAS 142 also requires that intangible assets with
            definite useful lives be amortized over their respective estimated
            useful lives to their estimated residual values, and reviewed for
            impairment in accordance with SFAS 121, "Accounting for the
            Impairment of Long-Lived Assets and for Long-Lived Assets to Be
            Disposed Of".

                The Company is required to adopt the provisions of SFAS 141
            immediately, and Management expects to adopt the provisions of SFAS
            142 effective October 1, 2001, the beginning of the Company's fiscal
            year 2002.

                SFAS 141 will require that upon adoption of SFAS 142, the
            Company evaluate its existing intangible assets and goodwill, and
            make any necessary reclassifications in order to conform with the
            new criteria in SFAS 141. Upon adoption of SFAS 142, the Company
            plans to reassess the useful lives and residual values of all
            recorded intangible assets, other than goodwill, and make any
            necessary amortization period adjustments by December 31, 2001. In
            addition, to the extent an intangible asset is identified as having
            an indefinite useful life, the Company will be required to test the
            intangible asset for impairment in accordance with the provisions of
            SFAS 142 by December 31, 2001. Any impairment loss will be measured
            as of the date of adoption and recognized as the cumulative effect
            of a change in accounting principle. Upon adoption of SFAS 141 and
            SFAS 142, the Company does not anticipate a material impact to the
            carrying value of the Company's goodwill.

2.   Acquisitions/Divestitures

                On June 8, 2001, the Company acquired all of the outstanding
            common stock of Bea Filtri S.p.A. (Bea) for approximately $13.5
            million in cash and debt. Bea, headquartered in Milan, Italy, is a
            supplier of filtration products to the pharmaceutical, food and
            beverage, healthcare, and petrochemical markets. Bea broadens the
            Company's microfiltration product offering and increases the
            Company's penetration in European markets. Bea's assets and
            liabilities, and related operating results, since the date of
            acquisition, are included within the Company's Filtration/Fluid Flow
            segment.

                On June 2, 2000, the Company purchased Holaday Industries, Inc.
            (Holaday) for approximately $4 million in cash. Holaday,
            headquartered in Eden Prairie, MN, is a leading supplier of
            specialty measurement probes to the EMC test, health and safety, and
            microwave markets. The operating results for Holaday, since the date
            of acquisition, are included within the Company's Test segment

                On April 9, 2000, the Company acquired all of the outstanding
            common stock of Lindgren RF Enclosures, Inc. (formerly known as The
            Curran Company) and Lindgren, Inc. (doing business through its
            subsidiary, Rayproof Ltd.) (collectively Lindgren) for approximately
            $22 million in cash plus additional consideration based upon the
            future operating performance of Lindgren. Lindgren is a leading
            supplier of radio frequency (RF) shielding products and components
            used by manufacturers of medical equipment, communications systems
            and electronic products. The operating results for Lindgren, since
            the date of acquisition, are included within the Company's Test
            segment.

                On March 31, 2000, the Company acquired the Eaton space products
            business (Eaton), formerly located in El Segundo, CA, for
            approximately $6 million in cash. Eaton manufactures specialty
            valves and other fluid flow components for satellite launch vehicles
            and aircraft applications and has been integrated into the Company's
            Filtration/Fluid Flow segment, since the date of acquisition.

                In February 2000, the Company completed the sale of its
            microwave antenna business, which had historically operated as part
            of Rantec Microwave & Electronics, Inc. The Company transferred the
            contract order backlog and operating assets of the microwave antenna
            business for $2.1 million in cash, and in September 2000, sold the
            related land and buildings in Calabasas, CA for approximately $6
            million.


                                                                              31


2001 ESCO TECHNOLOGIES ANNUAL REPORT
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


                Assuming the acquisitions of Holaday, Lindgren and Eaton as well
           as the divestiture of the Rantec microwave antenna business had
           occurred on October 1, 1999, (the beginning of fiscal 2000), pro
           forma unaudited net sales, net earnings and diluted EPS for the year
           ended September 30, 2000 would have been approximately $325 million,
           $17.3 million and $1.36 per share, respectively. These unaudited pro
           forma amounts are not necessarily indicative of the results of
           operations that would have occurred had these actions been completed
           on October 1, 1999, or of future results of operations.

                On September 30, 1999, the Company completed the sale of its
           Systems & Electronics Inc. (SEI) subsidiary to Engineered Support
           Systems, Inc. The Company sold 100% of the common stock of SEI for
           $85 million in cash, less working capital adjustments, resulting in a
           $59.9 million gain recorded in the 1999 results of operations.
           Certain assets and liabilities of SEI were retained by the Company,
           including the net operating loss carryforward.

                Included in the 1999 consolidated statements of operations are
           the operating results of SEI prior to its divestiture as follows: net
           sales of $172.8 million; cost of sales of $139.6 million, SG&A
           expenses of $21.6 million; other costs and expenses, net, of $0.9
           million; and earnings before income taxes of $10.7 million.

                All of the Company's acquisitions have been accounted for using
           the purchase method of accounting and accordingly, the respective
           purchase prices were allocated to the assets (including intangible
           assets) acquired and liabilities assumed based on estimated fair
           values at the date of acquisition. The financial results from these
           acquisitions have been included in the Company's financial statements
           from the date of acquisition. The goodwill recorded as a result of
           the transactions is being amortized over 20 years, until the adoption
           of SFAS 142.


      3. Accounts receivable

                Accounts receivable consist of the following at September 30,
            2001 and 2000:

<Table>

                Commercial accounts receivable increased primarily due to the
            acquisition of Bea in 2001.


      4. Inventories

                Inventories consist of the following at September 30, 2001 and

</Table>

                Inventories increased approximately $3.7 million mainly to
            support the near term sales demand and due to the acquisition of Bea
            in 2001.

            these operating leases for the years ended September 30, 2001, 2000
            and 1999 amounted to $6.8 million, $5.0 million and $6.3 million,
            respectively. Future aggregate minimum lease payments under

                Based on the Company's historical pretax income, together with
            the projection of future taxable income, Management believes it is
            more likely than not that the Company will realize the benefits of
            the net deferred tax asset existing at September 30, 2001. In order
            to realize the aforementioned net deferred tax asset, the Company
            will need to generate future taxable income of approximately $154
            million, of which $130 million is required to be realized prior to
            the expiration of the net operating loss (NOL) carryforward, of
            which $8 million will expire in 2006; $6 million will expire in
            2007; $23 million will expire in 2009; $38 million will expire in
            2010; $4 million will expire in 2011; $11 million will expire in
            2018; and $40 million will expire in 2019. The net operating loss
            carryforward may be used to reduce future income tax cash payments.

                In 2001, as the result of certain residual tax effects related
            to the fiscal 2000 sale of the property in Calabasas, CA, the
            Company utilized approximately $2 million of the remaining $33
            million capital loss carryforward available from the sale of its
            Hazeltine subsidiary in 1996. The remaining capital loss
            carryforward of approximately $31 million expired on September 30,
            2001.

                The valuation reserve in the amount of $10.8 million maintained
            for the deferred tax asset represented by the capital loss
            carryforward was eliminated by the expiration of the capital loss
            carryforward. In addition, in 2001, the Company eliminated its
            remaining net deferred tax valuation allowance of $12.7 million,
            which was the allowance representing the amount of the deferred tax
            asset associated with temporary differences and NOLs which
            Management believed would likely not be realized due to limitations
            on future use.

                On April 11, 2000, the Company entered into a $75 million
            revolving credit facility, with the option to increase it to $100
            million through April 11, 2002. The credit facility was amended on
            February 28, 2001 to allow for borrowings in foreign currencies. The
            credit facility is available for direct borrowings and/or the
            issuance of letters of credit. The maturity of the bank credit
            facility is April 11, 2005, and is provided by a group of five
            banks, led by Bank of America. At September 30, 2001, the Company
            had approximately $61.7 million available to borrow under the credit
            facility as well as $14.5 million of cash on hand.

                The credit facility requires, as determined by certain financial
            ratios, a commitment fee ranging from 20-30 basis points per annum
            on the unused portion. The terms of the facility provide that
            interest on borrowings may be calculated at a spread over the London
            Interbank Offered Rate (LIBOR) or based on the prime rate, at the
            Company's election. Substantially all of the assets of the Company
            are pledged under the credit facility. The financial covenants of
            the credit facility include limitations on leverage and minimum
            consolidated EBITDA. As of September 30, 2001, the Company is in
            compliance with all bank covenants.

                During 2001 and 2000, the maximum aggregate short-term
            borrowings at any month-end were $5.5 million and $21 million,
            respectively; the average aggregate short-term borrowings
            outstanding based on month-end balances were $1.7 million and $8.1
            million, respectively; and the weighted average interest rates were
            6.4% in 2001, 7.5% in 2000 and 6.3% in 1999. The letters of credit
            issued and outstanding under the credit facility totaled $6.1
            million and $7.9 million at September 30, 2001 and 2000,
            respectively. Short-term borrowings under the credit facility
            totaled zero and $4.0 million as of September 30, 2001 and 2000,
            respectively. Long-term borrowings under the revolving credit
            facility were $7.2 million (related to the Bea acquisition and based
            in the local currency) and zero at September 30, 2001 and 2000,
            respectively. In addition, the Company has other borrowings in
            foreign countries of approximately $1.2 million, of which $0.1
            million is due within one year.


      8. Capital stock

                The 13,409,934 and 13,224,834 common shares as presented in the
            accompanying Consolidated Balance Sheets at September 30, 2001 and
            2000 represent the actual number of shares issued at the respective

            treasury at September 30, 2001 and 2000, respectively.

                In conjunction with the sale of SEI on September 30, 1999, the
            previously outstanding Deposit and Trust Agreement was terminated.
            The Company has various Stock Option Plans which permit the Company
            to grant key management employees (1) options to purchase shares of
            the Company's common stock or (2) stock appreciation rights with
            respect to all or any part of the number of shares covered by the
            options. All outstanding options were granted at prices equal to
            fair market value at the date of grant.

                The options have a ten year contractual life from date of
            issuance, expiring in various periods through 2011. The increase in
            exercised shares and cancelled shares in 2000 is mainly due to the
            sale of SEI. Employees of SEI had 90 days, subsequent to the
            divestiture, to exercise their exercisable stock options prior to
            their cancellation.

                In February 2001, the Company authorized a stock repurchase
            program 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. Approximately 77,000, 516,000 and
            177,000 shares were repurchased during fiscal years 2001, 2000 and
            1999, respectively.

                During 2001, the Board of Directors authorized, and the
            shareholders approved, the Performance Share Plan (the Plan). The
            maximum number of shares available for issue under the Plan was
            532,814 shares. As of September 30, 2001, 331,831 shares have been
            awarded and 80,000 shares have been earned. At September 30, 2001,
            there were 40,000 shares of restricted stock outstanding.

                In February 2000, the Company amended and restated the Preferred
            Stock Purchase Rights Plan such that each Right entitles the holder
            to purchase one one-hundredth of a share of preferred stock at an
            initial purchase price of $60. The Rights remain in existence until
            February 3, 2010, unless renewed, redeemed earlier (at one cent per
            Right), exercised or exchanged under the terms of the plan. Under
            certain conditions involving the acquisition of, or an offer for,
            20% or more of the Company's common stock, all holders of Rights,
            except an acquiring entity, would be entitled (1) to purchase, at a
            defined price, common stock of the Company or an acquiring entity at
            a value twice the defined price, or (2) at the option of the Board,
            to exchange each Right for one share of common stock.

                The Company adopted the disclosure-only provisions of SFAS No.
            123. Under APB No. 25, no compensation cost was recognized for the
            Company's stock option plans. Had compensation cost for the
            Company's stock option plans and performance share plans been
            determined based on the fair value at the grant date for awards
            outstanding during 2001 and 2000 consistent with the provisions of
            this Statement, the Company's net earnings and net earnings per
            share would have been as shown in the table below:

                The fair value of each option grant is estimated on the date of
            grant using the Black-Scholes option-pricing model with the
            following weighted-average assumptions used for grants in 2001 and
            2000, respectively: expected dividend yield of 0% in both periods;
            expected volatility of 37.5% and 29.2%, risk-free interest rate of
            4.6% and 5.8%, and expected life based on historical exercise
            periods of 4.21 years and 4.06 years.

                To determine the fair value of grants under the Performance
            Share Plans, the probability that performance milestones would be
            met was applied to the ESCO stock price on the date of grant. This
            probability was based on an estimated average annual growth rate of
            10.0% and an annualized volatility of 37.9% and 38.3% in 2001 and
            2000, respectively.

      9. Retirement and other benefit plans

                Substantially all employees are covered by defined benefit or
            defined contribution pension plans maintained by the Company for the
            benefit of its employees. Benefits are provided to employees under
            defined benefit pay-related and flat-dollar plans, which are
            primarily noncontributory. Annual contributions to retirement plans
            equal or exceed the minimum funding requirements of the Employee
            Retirement Income Security Act or applicable local regulations. On
            September 30, 1999, the Company completed the sale of SEI to
            Engineered Support Systems, Inc. which accounts for significant
            fluctuations in amounts in 2000 as compared to 1999.


                                                                              37

                The benefit obligations of the defined benefit plans as of
            September 30, 2001 and 2000 were based on discount rates of 7.25%
            and 7.75%, respectively, and an assumed rate of increase in
            compensation levels of 4.5% in 2001 and 2000.

                The 2001, 2000 and 1999 pension expense for the defined benefit
            plans was based on a 7.25%, 7.75% and 7.75% discount rate,
            respectively, a 4.5%, 4.5% and 4% increase in compensation levels,
            respectively, and a 9.5%, 9.5% and 10% expected long-term rate of
            return on plan assets, respectively.

                In addition to providing retirement income benefits, the Company
            provides unfunded postretirement health and life insurance benefits
            to certain retirees. To qualify, an employee must retire at age 55
            or later and the employee's age plus service must equal or exceed
            75. Retiree contributions are defined as a percentage of medical
            premiums. Consequently, retiree contributions increase with
            increases in the medical premiums. The life insurance plans are
            noncontributory and provide coverage of a flat dollar amount for
            qualifying retired employees.

                Net periodic postretirement benefit cost is comprised of the
            following:

                The net benefit obligations of the plans as of September 30,
            2001 and 2000 were based on discount rates of 7.25% and 7.75%,
            respectively. The September 30, 2001 net benefit obligation was
            based on a health care cost trend of 5.5% for fiscal 2001. The
            September 30, 2000 net benefit obligation was based on a health care
            cost trend of 6.5% for fiscal 2000, gradually grading down to an
            ultimate rate of 5.5% by 2002. A 1% increase in the health care cost
            trend rate for each year would increase the September 30, 2001 net
            benefit obligation by approximately $45,000, while a 1% decrease in
            the health care cost trend rate for each year would decrease the
            September 30, 2001 net benefit obligation by approximately $50,000.

                The fiscal 2001 and 2000 net periodic benefit costs were based
            on discount rates of 7.25% and 7.75%, respectively. The net periodic
            benefit cost was based on an assumed health care cost trend of 5.5%
            for 2001 and 6.5% for 2000 gradually grading down to 5.5% by fiscal
            year 2002. A 1% increase in the health care cost trend rate for each
            year would increase the aggregate of the service cost and interest
            cost components of the fiscal 2001 net periodic benefit cost by
            approximately $3,900, while a 1% decrease in the health care cost
            trend rate for each year would decrease the aggregate of the service
            cost and interest cost components of the fiscal 2001 net periodic
            benefit cost by approximately $4,600.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


                The increase in salaries and wages in 2001 compared to 2000 is
            due to the Company's acquisition activities. The decreases in
            salaries and wages and in research and development costs in 2000
            compared to 1999 are due to the sale of SEI in 1999. The increase in
            research and development costs in 2001 compared to 2000 is mainly
            due to the Company's acquisition activities and increased spending
            in the Company's Communications segment related to product

11.  Business segment information

                The Company is organized based on the products and services that
            it offers. Under this organizational structure, the Company operates
            in four principal segments: Filtration/Fluid Flow, Test,
            Communications and Other. Filtration/Fluid Flow operations consist
            of PTI Technologies Inc. (PTI) and Filtertek Inc. (Filtertek). PTI
            develops and manufactures a wide range of filtration products and is
            a leading supplier of filters to the commercial aerospace market and
            microfiltration market. Filtertek develops and manufactures a broad
            range of high-volume, original equipment manufacturer (OEM)
            filtration products at its facilities in North America, South
            America and Europe. Test segment operations represent the EMC Group,
            consisting of EMC Test Systems, L.P. (ETS) and Lindgren. The EMC
            Group is principally involved in the design and manufacture of EMC
            test equipment, test chambers, and electromagnetic absorption
            materials. The EMC Group also manufactures radio frequency (RF)
            shielding products and components used by manufacturers of medical
            equipment, communications systems, electronic products, and shielded
            rooms for high security data processing and secure communication.
            Communications operations consist of Distribution Control Systems,
            Inc. (DCSI) which is principally involved in providing two-way power
            line communication systems for the utility industry. These systems
            provide the electric utilities with a patented communication
            technology for demand-side management, distribution automation and
            automatic meter reading capabilities. Communications also includes
            the operations of Comtrak, L.L.C.

                The Divested Business segment consists of Systems & Electronics
            Inc. (SEI). As of September 30, 1999, ESCO sold SEI to Engineered
            Support Systems, Inc. The Other segment is principally comprised of
            Rantec Power Systems Inc., formerly a part of Rantec Microwave &
            Electronics, Inc. (Rantec) which produces power supplies widely used
            in high performance displays, such as cockpit instrumentation,
            engineering workstations and medical imaging. Rantec's microwave
            antenna business was sold in February 2000. Accounting policies of
            the segments are the same as those described in the summary of
            significant accounting policies in Note 1.

                In accordance with SFAS 131, the Company evaluates the
            performance of its operating segments based on operating profit,
            which is defined as: net sales, less cost of sales, and less SG&A
            expenses. Intersegment sales and transfers are not significant.
            Segment assets consist primarily of customer receivables,
            inventories and fixed assets directly associated with the production
            processes of the segment. Segment assets also include goodwill.
            Segment depreciation and amortization is based upon the direct
            assets listed above.

            Consolidated Statements of Operations, and which would be included
            in the determination of operating income as defined within generally

            of approximately $2.1 million of costs related to the
            Filtration/Fluid Flow segment as a result of the consolidation of
            PTI's filtration business into new facilities in Oxnard, CA;
            consolidation costs of the Stockton, CA manufacturing facility into
            the Huntley, IL facility; and other miscellaneous costs.

                In 2000, these items consist of approximately $2.0 million of
            net costs related to the Filtration/Fluid Flow segment as a result

            $1.0 million of Other costs and expenses, net, primarily related to
            the write-off of an investment in a third party EMC related start-up
            company which filed bankruptcy in 2000.

                The 1999 operating profit includes $3.9 million of other charges

2001 ESCO TECHNOLOGIES ANNUAL REPORT
Independent Auditors' Report

            THE BOARD OF DIRECTORS AND SHAREHOLDERS
            ESCO TECHNOLOGIES INC.:

                We have audited the accompanying consolidated balance sheets of
            ESCO Technologies Inc. and subsidiaries as of September 30, 2001 and
            2000, and the related consolidated statements of operations,
            shareholders' equity, and cash flows for each of the years in the
            three-year period ended September 30, 2001. These consolidated
            financial statements are the responsibility of the Company's
            Management. Our responsibility is to express an opinion on these
            consolidated financial statements based on our audits.

                We conducted our audits in accordance with auditing standards
            generally accepted in the United States of America. Those standards
            require that we plan and perform the audit to obtain reasonable
            assurance about whether the financial statements are free of
            material misstatement. An audit includes examining, on a test basis,
            evidence supporting the amounts and disclosures in the financial
            statements. An audit also includes assessing the accounting
            principles used and significant estimates made by management, as
            well as evaluating the overall financial statement presentation. We
            believe that our audits provide a reasonable basis for our opinion.

                In our opinion, the consolidated financial statements referred
            to above present fairly, in all material respects, the financial
            position of ESCO Technologies Inc. and subsidiaries as of September
            30, 2001 and 2000, and the results of their operations and their
            cash flows for each of the years in the three-year period ended
            September 30, 2001, in conformity with accounting principles
            generally accepted in the United States of America.

                As discussed in note 1 to the consolidated financial statements,
            in 1999, the Company adopted Statement of Position 98-5, "Reporting
            on the Costs of Start-Up Activities".
