those discussed below. See "Management's Discussion and Analysis" appearing in
the 2001 Annual Report.

PRODUCTS

The Company's products are described below. See Note 11 of the Notes to
Consolidated Financial Statements in the 2001 Annual Report, which Note is
herein incorporated by reference.

FILTRATION/FLUID FLOW

The Company's Filtration/Fluid Flow segment accounted for approximately
55% of the Company's total revenue in fiscal year 2001.

PTI Technologies Inc., PTI Advanced Filtration Inc., PTI Technologies
Limited and Bea develop and

manufacture a wide range of filtration products. PTI Technologies Inc. is a
leading supplier of filters to the commercial aerospace and industrial markets.
The industrial business includes the supply of filtration products for process
and mobile fluid power applications. PTI Advanced Filtration Inc. produces
microfiltration products for applications in microelectronic, food and beverage,
and pharmaceutical markets. Membrane separation products and systems are also
produced by PTI Advanced Filtration Inc. for use in the dairy industry and
industrial coatings applications. PTI Technologies Limited manufactures and
distributes filter products primarily in the European industrial marketplace.
Bea, acquired in June 2001, is a manufacturer and supplier of filtration
products to the pharmaceutical, food and beverage, healthcare and petro-chemical
markets, primarily in Europe. VACCO and PTI Technologies Inc. develop and
manufacture industrial filtration elements and systems primarily used within the

performance in very harsh environments. VACCO supplies flow control products to
the aerospace industry for use in aircraft, satellite propulsion systems,
satellite launch vehicles and the space shuttle. VACCO also uses its etched disc
technology to produce quiet valves and manifolds for U.S. Navy and severe
service industrial applications.

All of the Filtertek entities listed above under "THE COMPANY" are
hereinafter collectively referred to as "Filtertek". Filtertek develops and
manufactures a broad range of high-volume filtration products at its facilities
in North America, South America and Europe. Filtertek's products, which are
centered around its insert injection-molding technology wherein a filter medium
is inserted into the tooling prior to injection-molding of the filter housing,
have widespread applications in the medical and health care markets, automotive
fluid system market, and other commercial and industrial markets. Typical
Filtertek customers may require daily production of many thousands of units, at
very high levels of quality, that are generally produced in highly-automated
manufacturing cells. Many of Filtertek's products are produced utilizing
patented technology or incorporate proprietary product or process design, or
both. Filtertek's products are typically supplied to original equipment
manufacturers under long-term contracts. In fiscal year 2001, Filtertek
introduced a number of new products including automotive fuel injection and fuel
pump filters, newly patented transmission sump filters, blood filtration devices
and industrial products such as spray paint system filters.

TEST

The Company's Test segment accounted for approximately 25% of the
Company's total revenue in fiscal year 2001.

ETS designs and manufactures electromagnetic compatibility ("EMC") test
equipment. It also supplies controlled radio frequency ("RF") testing
environments (anechoic chambers) and electromagnetic absorption materials. ETS's
products include antennas, antenna masts, turntables, current probes, field
probes, TEM (transverse electromagnetic) cells, GTEM (gigahertz transverse
electromagnetic) cells, calibration equipment and other test accessories
required to perform a variety of RF tests. ETS also provides all the design,
program management and integration services required to supply customers with
turnkey EMC solutions. In fiscal year 1999, ETS was awarded a contract by
General Motors, valued at more than $20 million, to design and equip an EMC test
facility. Revenue from this contract, which was substantially completed during
fiscal year 2001, amounted to approximately 5% of total revenue for the Test
segment in fiscal year 2001.

Lindgren designs, manufactures, installs and services electromagnetic
("EM") shielding systems used in medical equipment, wireless communication
product testing and electronics products. Lindgren's products include RF and
magnetic shielding for magnetic resonance imaging ("MRI") rooms, shielded test
enclosures, RF filters, fiber optic interface components, active magnetic field
compensation systems, and a line of proprietary doors designed specifically for
EM isolation, containment and measurement applications. Lindgren also supplies
special high performance RF and acoustic shielded rooms for secure data
processing and communications for government security applications.

Euroshield OY designs and manufactures a broad range of modular shielding
systems and shielded doors, some of which are proprietary, for the world market.
It also provides the design, program management and integration services to
supply the European market with turnkey solutions.

Holaday designs and manufactures specialty measurement probes for use in
broadband and EMC test, health and safety, and microwave detection products.
Holaday's products include probes, meters, analysis

software, personal protection equipment and components used by original
equipment manufacturers and service professionals. Holaday also performs
calibration certification services for its probes and meters.

COMMUNICATIONS

In fiscal year 2001, approximately 17% of the Company's total revenue was
derived from its Communications segment.

DCSI is a leading manufacturer of two-way power line communication
systems for the utility industry. These systems provide electric utilities with
a patented communication technology for automatic meter reading, demand-side
management and distribution automation (the TWACS(R) system). Revenue from the
TWACS systems accounted for approximately 16%, 14% and 6% of the Company's
consolidated revenue in fiscal years 2001, 2000 and 1999, respectively. During
fiscal year 2001, DCSI (through its subsidiary, DCSI-Caribe) received
substantial revenue from shipments of an automatic meter reading ("AMR") system
to the Puerto Rico Electric Power Authority ("PREPA") under a multi-year
contract signed in fiscal year 1998. Revenue from this contract amounted to
approximately 34% of total Communications segment revenue in fiscal year 2001,
when deliveries were completed. PREPA has awarded DCSI-Caribe a follow-on
contract running from fiscal 2001 to fiscal 2006 which has a value of
approximately $50 million. Revenue from this contract is expected to constitute
approximately 15% of total Communications segment revenue in fiscal year 2002.
During 1999, DCSI was chosen to supply the first phase of an AMR project to
Wisconsin Public Service Co. ("WPS"). The first phase was completed during
fiscal 2001. WPS has awarded DCSI a follow-on contract in the amount of $9.3
million, which is expected to be completed during fiscal 2002. In addition, in
October 2001 DCSI received in excess of $30 million in new orders from a total
of six customers, including Lee County (Florida) Electric Co-op, Inc. and
Perdenales (Texas) Electric Co-op, Inc.

Comtrak has developed an advanced video security monitoring system, which
has applications in commercial and industrial security systems. Currently,
Comtrak is working jointly with ADT Security Services, Inc., who is selling this
system under its SecurVision(R) trademark to a variety of markets.

OTHER

The Company's Other products segment represented approximately 3% of the
Company's total revenue in fiscal year 2001.

Rantec designs and manufactures high voltage and low voltage power
supplies, DC to DC converters and power systems, which are marketed to a broad
range of customers worldwide. Applications include medical and avionics CRT
displays, as well as ground-based, shipboard and airborne power systems. Rantec
has continued its development of state-of-the art, patented, miniature high
voltage technology, which provides the same basic functions of today's high
voltage power supplies and reduces package size by 80%.

MARKETING AND SALES

The Company's Filtration/Fluid Flow and Test segments' products generally
are distributed to customers through a domestic and foreign network of
distributors, sales representatives and factory salespersons. The Communications
and Other segments' systems are primarily sold directly to the respective end
users; however, the Communications segment utilizes distributors to sell its
systems to the electric co-op market.

The Company's international sales (excluding sales of ESCO's former
Systems & Electronics Inc. ("SEI") subsidiary which was sold on September 30,
1999) accounted for approximately 22%, 23% and 13% of the Company's total sales
in the fiscal years ended September 30, 2001, 2000 and 1999, respectively. The
increases since fiscal year 1999 were primarily due to increased sales at ETS
and Filtertek and the acquisition of Lindgren. See Note 11 of the Notes to
Consolidated Financial Statements in the 2001 Annual Report. Since the
divestiture of SEI, international sales have been derived primarily from
industrial and commercial products rather than defense products.

The Company's international sales are subject to risks inherent in
foreign commerce, including currency

fluctuations and devaluations, the risk of war, changes in foreign governments
and their policies, differences in foreign laws, uncertainties as to enforcement
of contract rights, and difficulties in negotiating and litigating with foreign
customers.

Some of the Company's products are sold directly or indirectly to the
U.S. Government under contracts with the Army, Navy and Air Force and
subcontracts with prime contractors of such entities. Excluding SEI results,
direct and indirect sales to the U.S. Government accounted for approximately
12%, 8% and 10% of the Company's total sales in the fiscal years ended September
30, 2001, 2000 and 1999, respectively.

INTELLECTUAL PROPERTY

The Company owns or has other rights in various forms of intellectual
property (i.e., patents, trademarks, service marks, copyrights, mask works,
trade secrets and other items). As a major supplier of engineered products to
growing industrial and commercial markets, the Company emphasizes developing
intellectual property and protecting its rights therein. However, the scope of
protection afforded by intellectual property rights, including those of the
Company, is often uncertain and involves complex legal and factual issues. Some
intellectual property rights, such as patents, have only a limited term. With
respect to patents, there can be no assurance that issued patents will not be
infringed or designed around by others. In addition, the Company may not elect
to pursue an infringer due to the high costs and uncertainties associated with
litigation. Further, there can be no assurance that courts will ultimately hold
issued patents valid and enforceable.

With respect to the Filtration/Fluid Flow segment, an increasing number
of products are based on patented or otherwise proprietary technology that sets
them apart from the competition. In the Test and Other segments, patent
protection is sought for significant inventions. In the Communications segment,
many of the products are based on patented or otherwise proprietary technology.

The Company considers its patent and other intellectual property to be
of significant value in each of its segments. The Communications segment owns
intellectual property which it deems necessary or desirable for the manufacture,
use or sale of its products. No other segment is materially dependent on any
single patent, group of patents or other intellectual property.

BACKLOG

The backlog of firm orders at September 30, 2001 and September 30, 2000,
respectively, was: $70.8 million and $73.5 million for Filtration/Fluid Flow;
$27.4 million and $33.9 million for Test; $72.8 million and $27.9 million for
Communications; and $9.1 million and $10.1 million for Other. As of September
30, 2001, it is estimated that domestic customers accounted for approximately
77% of the Company's total firm orders, and international customers accounted
for approximately 23%. Of the Company's total backlog of orders at September 30,
2001, approximately 86% is expected to be completed in the fiscal year ending
September 30, 2002.

PURCHASED COMPONENTS AND RAW MATERIALS

The Company's products require a wide variety of components and
materials. Although the Company has multiple sources of supply for most of its
material requirements, certain components and raw materials are supplied by
sole-source vendors, and the Company's ability to perform certain contracts
depends on their performance. In the past, these required raw materials and
various purchased components generally have been available in sufficient
quantities. The Test segment is a vertically integrated supplier of EM shielding
products, producing most of its critical RF components. This capability enables
the Test segment to control the level of quality, RF performance and delivery
response time for its customers. In the Communications segment, DCSI utilizes a
single source or a limited number of sources to produce substantially all of
DCSI's end-products. Although the Company believes alternative suppliers of
components and end-products are available, the inability of DCSI to develop
alternative sources quickly or cost-effectively could have a material adverse
effect on the Communications segment.

COMPETITION

Competition in the Company's major markets is broadly based and global in
scope. The Company faces intense competition from a large number of firms for
nearly all of its products. Competition can be particularly intense during
periods of economic slowdown, and this has been experienced in the past in some
of the Filtration/Fluid Flow markets. Although the Company is a leading supplier
in several of the markets it serves, it maintains a relatively small share of
the business in many of the markets in which it participates. Individual
competitors range in size from annual revenues of less than $1 million to
billion dollar enterprises. Because of the specialized nature of the Company's
products, it is impossible to state precisely its competitive position with
respect to its products. Substantial efforts are required in order to maintain
existing business levels. In the Company's major served markets, competition is
driven primarily by quality, technology, price and delivery performance. The
following information concerns the Company's primary segments.

Pall Corporation is a major competitor in the Filtration/Fluid Flow
market. Other significant competitors in this market include Millipore Corp.,
Osmonics Inc. and Cuno Inc.

The Test segment is the global leader in the EM shielding market.
Significant competitors in this served market include Braden Shielding Systems
and TDK RF Solutions Inc.

Primary competitors of the Communications segment in the utility
communications market include Itron, Inc. and Schlumberger Limited.

RESEARCH AND DEVELOPMENT

Research and development and the Company's technological expertise are
important factors in the Company's business. Research and development programs
are designed to develop technology for new products or to extend or upgrade the
capability of existing products, and to enhance their commercial potential.

The following information excludes expenses attributable to SEI. The
Company performs research and development at its own expense, and also engages
in research and development funded by customers. For the fiscal years ended
September 30, 2001, 2000 and 1999, total Company-sponsored research and
development expenses were approximately $9.4 million, $6.2 million and $6.3
million, respectively. The increase in fiscal 2001 for Company-sponsored
research and development expenses was due to additional investments made within
the Filtration/Fluid Flow and Communications segments. Total customer-sponsored
research and development expenses were approximately $5.2 million, $4.0 million
and $8.3 million for the fiscal years ended September 30, 2001, 2000 and 1999,
respectively. The decreases since fiscal year 1999 for customer-sponsored
research and development expenses were due primarily to lower activity at
Rantec, as well as the sale of the Rantec microwave antenna business. All of the
foregoing expense amounts exclude certain engineering costs primarily associated
with product line extensions, modifications and maintenance, which amounted to
approximately $10.8 million and $8.4 million for the fiscal years ended
September 30, 2001 and 2000, respectively.

ENVIRONMENTAL MATTERS

The Company is involved in various stages of investigation and cleanup
relating to environmental matters. It is very difficult to estimate the
potential costs of such matters and the possible impact of these costs on the
Company at this time due in part to: the uncertainty regarding the extent of
pollution; the complexity of Government laws and regulations and their
interpretations; the varying costs and effectiveness of alternative cleanup
technologies and methods; the uncertain level of insurance or other types of
cost recovery; and in the case of off-site waste disposal facilities, the
uncertain level of the Company's relative involvement and the possibility of
joint and several liability with other contributors under applicable law. Based
on information currently available, the Company does not believe that the
aggregate costs involved in the resolution of any of its environmental matters
will have a material adverse effect on the Company's financial statements.

GOVERNMENT CONTRACTS

The Company's contracts with the U.S. Government and subcontracts with
prime contractors of the U.S. Government are primarily firm fixed price
contracts under which work is performed and paid for at a fixed amount without
adjustment for the actual costs experienced in connection with the contracts.
Therefore, unless the customer actually or constructively alters or impedes the
work performed, all risk of loss due to cost overruns is borne by the Company.
All Government prime contracts and virtually all of the Company's subcontracts
provide that they may be terminated at the convenience of the Government. Upon
such termination, the Company is normally entitled to receive equitable
compensation for same. See "Marketing And Sales" in this Item 1.

EMPLOYEES

As of November 30, 2001, the Company employed approximately 2,400
persons. Approximately 230 of these employees are covered by a collective
bargaining agreement, which will expire in fiscal year 2005.

FINANCING

On April 11, 2000, the Company entered into a $75 million revolving
credit facility replacing its previous $40 million credit facility. The $75
million credit facility has the following scheduled reductions: $9,750,000 on
April 11, 2002, $10,500,000 on April 11, 2003, $9,750,000 on April 11, 2004, and
the remaining balance is due upon maturity and expiration, April 11, 2005. The
credit facility was amended on February 28, 2001 to allow for borrowings in
foreign currencies. The Company maintains the option to increase the credit
facility by $25 million through April 11, 2002. The credit facility is available
for direct borrowings and/or the issuance of letters of credit. The credit
facility contains customary events of default, including change in control of
the Company. The credit facility is provided by a group of five banks, led by
Bank of America. Substantially all of the assets of the Company are pledged
under the credit facility. See "Management's Discussion and Analysis--Capital
Resources & Liquidity" in the 2001 Annual Report, and Note 7 of the Notes to
Consolidated Financial Statements in the 2001 Annual Report, which Note is
herein incorporated by reference.

HISTORY OF THE BUSINESS

ESCO was incorporated in Missouri in August 1990 as a wholly-owned
subsidiary of Emerson Electric Co. ("Emerson") to be the indirect holding
company for several Emerson subsidiaries, which were primarily in the defense
business. Ownership of ESCO and its subsidiaries was distributed on October 19,
1990 by Emerson to its shareholders through a special distribution. Effective
July 10, 2000, ESCO changed its name from ESCO Electronics Corporation to ESCO
Technologies Inc.

On June 8, 2001, the Company acquired the stock of Bea Filtri, S.p.A.,
and integrated this business into the Filtration/Fluid Flow segment.

In fiscal year 2001, the Company completed the consolidation of the Eaton
fluid flow components business into VACCO's facility at South El Monte,
California; closed redundant facilities of the Test segment in Riviera Beach,
Florida and of the Filtration/Fluid Flow segment in Stockton, California; and
made significant progress in consolidating operations in the Test segment.
