                                     PART I

Item 1. Business

GENERAL

         Insituform Technologies, Inc. (the "Company" or "Insituform
Technologies") is a worldwide company specializing in the use of trenchless
technologies to rehabilitate, replace, maintain and install underground pipes.
The Company uses a variety of trenchless technologies. The Insituform(R)
cured-in-place pipe process (the "Insituform CIPP Process") contributed
approximately 65.5% of the Company's revenues during the Company's most recent
fiscal year.

         The Company was incorporated in Delaware in 1980, under the name
Insituform of North America, Inc. The Company was originally formed to act as
the exclusive licensee of the Insituform CIPP Process in most of the United
States. When the Company acquired its licensor in 1992, the name of the Company
was changed to Insituform Technologies, Inc. As a result of its successive
licensee acquisitions, the Company's business model has evolved from licensing
technology and manufacturing materials to performing the entire Insituform CIPP
Process itself.

         In February 2001, the Company acquired Kinsel Industries, Inc.
("Kinsel"), a trans-regional provider of pipebursting and other sewer
rehabilitation services. In 2000, Kinsel had total revenues of approximately
$100 million, which included approximately $18 million from its wastewater
treatment plant operations, approximately $32 million from trenchless pipe
rehabilitation services and some open-cut pipe construction, and approximately
$50 million from highway, bridge, airport and commercial construction. During
2001, the Company determined that, while valuable and profitable, the Kinsel
wastewater treatment plant operations and the Kinsel highway construction and
maintenance operations did not fit the Company's business strategy, and
classified these operations as discontinued. In February 2002 (with a January
2002 effective date), the Company closed the sale of Kinsel's wastewater
treatment plant operations and recorded a slight loss on the sale. The Company
closed the sale of Kinsel's highway construction operations in September 2002
with a pre-tax gain of $1.5 million. In October 2002, the Company closed the
sale of Kinsel's highway maintenance operations with no gain or loss recorded on
the sale.

         Effective May 1, 2002, the Company acquired the business and certain
assets and liabilities of Elmore Pipe Jacking, Inc. ("Elmore"), a tunneling and
pipe jacking provider operating primarily in the western United States. The
Elmore division, which is part of the tunneling segment, had approximately $20.7
million of revenues after the acquisition in 2002.

         As used in this Annual Report on Form 10-K, the terms "Company" and
"Insituform Technologies" refer to the Company and, unless the context otherwise
requires, its direct and indirect wholly-owned subsidiaries. For certain
information concerning each of the Company's industry segments and each of its
domestic and foreign operations, see Note 15 of the Notes to the Company's
Consolidated Financial Statements included in response to "Item 15. Exhibits,
Financial Statement Schedules, and Reports on Form 8-K," which is incorporated
herein by reference.

         The Company's website is www.insituform.com. The Company makes
available on this website under "Investor Relations - SEC," free of charge, its
annual report on Form 10-K, quarterly reports on Form 10-Q and current reports
on Form 8-K (and amendments to those reports) as soon as reasonably practicable
after the Company electronically files such material with, or furnishes it to,
the Securities and Exchange Commission.

TECHNOLOGIES

         Pipeline System Rehabilitation

                  The Insituform CIPP Process for the rehabilitation of sewers,
                  pipelines and other conduits utilizes a custom-manufactured
                  tube, or liner, made of a synthetic fiber. After the tube is
                  saturated (impregnated) with a thermosetting resin mixture, it
                  is installed in the host pipe by various processes and the
                  resin is then hardened, usually by heating it by various
                  means, forming a new rigid pipe within a pipe.

                  Pipebursting is a trenchless method for replacing deteriorated
                  or undersized pipelines. A bursting head is propelled through
                  the existing pipeline, fracturing the host pipe and displacing
                  the fragments outward, allowing a new pipe to be pulled in to
                  replace the old line. Pipes can be replaced size-for-size or
                  upsized.

                  Microtunneling is a trenchless method of drilling a new tunnel
                  from surface operated equipment. Microtunneling is typically
                  used for gravity sewers at depths greater than 15 feet, in
                  congested areas, where unstable ground conditions exist, where
                  construction is below the water table, or where contamination
                  zones are present.

                  Sliplining is a method used to push or pull a new pipeline
                  into an old one. With segmented sliplining, short segments of
                  pipe are joined to form the new pipe. For gravity sewer
                  rehabilitation, these short segments can often be joined in a
                  manhole or access structure, eliminating the need for a large
                  pulling pit.

                  The Insituform SP(TM) (Structural Panels) Process uses a
                  proprietary product to rehabilitate large diameter sanitary or
                  storm sewers. A proprietary process is used to construct
                  fiberglass reinforced panels to custom size and thickness. The
                  panels are individually placed in the sewer and the seams are
                  sealed.

                  See "Patents and Licenses" below for information concerning
                  these technologies and the Company's NuPipe(R) process (the
                  "NuPipe Process") and Thermopipe(R) process (the "Thermopipe
                  Process"), which were not material to the Company's results of
                  operations during the year ended December 31, 2002.

         Tunneling

         Tunneling typically encompasses the construction of man-entry sized
pipelines with access through vertical shafts. From the vertical shaft, a tunnel
is constructed using a steerable, locally-controlled tunnel boring machine. Pipe
is installed after the tunnel is constructed.

         TiteLiner(R) Process

         The Company's TiteLiner(R) process (the "TiteLiner Process") is a
method of lining new and existing steel pipe with a corrosion and abrasion
resistant polyethylene pipe.

                                       2



REHABILITATION ACTIVITIES

         The Company's rehabilitation activities are conducted principally
through installation and other construction operations performed directly by the
Company or through wholly-owned and, in some cases, majority-owned,
subsidiaries. In those areas of the world in which the Company's management
believes it would not be desirable for the Company to exploit its trenchless
processes directly, and in a portion of the United States, the Company has
granted licenses to unaffiliated companies. As described under "Ownership
Interests in Licensees" below, the Company has also entered into joint ventures
from time to time to exploit its trenchless rehabilitation processes. Under
these contractual joint venture relationships, work is bid by the joint venture
entity and subcontracted to the joint venture partners or to third parties. The
joint venture partners are primarily responsible for their subcontracted work,
but both joint venture partners are liable to the customer for all of the work.
Revenue and associated costs are recorded using percentage of completion
accounting for the Company's subcontracted portion of the total contract.

         The Company's principal rehabilitation activities are conducted in
North America directly by the Company or through subsidiaries. The Company holds
the Insituform CIPP Process rights for the United States and Canada. In North
America, the Company practices the Insituform CIPP Process in substantially all
of 44 of the 50 states and in Canada. Significant pipebursting rehabilitation
activities are conducted in the southeastern and western regions of the United
States by the Company and its subsidiary, Kinsel.

         North American rehabilitation operations, including research and
development, engineering, training and financial support systems, are
headquartered in Chesterfield, Missouri. Insituform CIPP Process tube
manufacturing and installation facilities are maintained in approximately 13
locations, geographically dispersed throughout the United States and Canada.

         Outside of North America, the Company conducts Insituform CIPP Process
rehabilitation operations through subsidiaries in the United Kingdom, France,
Spain, the Netherlands and Belgium. Through its French subsidiary, Video
Injection S.A. ("Video Injection"), acquired in 1998, the Company utilizes
multifunctional robotic devices developed by Video Injection in connection with
the inspection and repair of pipelines.

         European operations are headquartered in Rueil Malmaison, France, a
suburb of Paris, with principal regional facilities located in the United
Kingdom, the Netherlands, Spain, Belgium and Mitry Mory, France.

         The Company conducts tunneling, microtunneling and a range of pipe
system rehabilitation services throughout the United States through its
wholly-owned subsidiaries, Affholder, Inc. and Kinsel Industries, Inc.

         TiteLiner Process operations (which offer corrosion and abrasion
protection work) are conducted in the United States through the Company's United
Pipeline Systems division. Worldwide TiteLiner Process operations are
headquartered in the United States. Outside the United States, TiteLiner Process
installation activities are conducted through various operating subsidiaries.

         Most of the Company's installation operations are project-oriented
contracts for governmental entities. The contracts are usually obtained through
competitive bidding or negotiations and require performance at a fixed price.
The profitability of these contracts depends heavily upon the competitive
bidding environment, the Company's ability to estimate costs accurately and the
Company's ability to effectively manage and execute project performance. Project
estimates may prove to be inaccurate due to unforeseen conditions or events. A
substantial portion of the work on any given project may be subcontracted out to
third parties at a significantly lower profitability level to the Company than
work

                                       3


conducted directly by it. Also, proper trenchless installation requires
expertise that is acquired on the job and through training. The Company,
therefore, provides ongoing training and appropriate equipment to its field
installation crews.

         The overall profitability of the Company's installation operations is
influenced not only by the profitability of specific project contracts, but also
by the volume and timing of projects so that the installation operations are
able to operate at, or near, capacity.

         The Company is required to carry insurance and provide bonding in
connection with certain installation projects and, therefore, maintains
comprehensive insurance policies, including workers' compensation, general and
automobile liability, and property coverage. The Company believes that it
presently maintains adequate insurance coverage for all installation activities.
The Company has also arranged bonding capacity for bid, performance and payment
bonds. Typically, the cost of a performance bond is less than approximately 1%
of the contract value. The Company is required to indemnify surety companies for
any payments the sureties are required to make under the bonds.

         The Company generally invoices its customers as work is completed.
Under ordinary circumstances, collection from governmental agencies in the
United States is made within 60 to 90 days of billing. In most cases, 5% to 15%
of the contract value is withheld by the owner until testing is completed or the
warranty period has expired.

         The Company's principal rehabilitation activities are also conducted
through the following majority-owned subsidiaries:

         and is subject to purchase by the Company in September 2003 (or earlier
         upon specified events), and by certain of the Company's principal
         employees to comply with specific legal requirements.

(2)      The remaining interest is held by Per Aarsleff A/S.

LICENSEES

         The Company has granted licenses for the Insituform CIPP Process and
the NuPipe Process, covering exclusive and non-exclusive territories, to
licensees who provide pipeline repair and rehabilitation services throughout
their respective licensed territories. At present, the Insituform CIPP Process
is licensed to 11 unaffiliated licensees and sublicensees, and the NuPipe
Process is licensed to three unaffiliated licensees. The licenses generally
grant to the licensee the right to utilize the know-how and the patent rights
(where they exist) relating to the subject process, and to use the Company's
copyrights and trademarks.

         The Company's licensees generally are obligated to pay a royalty at a
specified rate, which in many cases is subject to a minimum royalty payment. An
unaffiliated domestic licensee is obligated to pay specified royalty surcharges
on its sales and contracts outside of its licensed territories. Any improvements
or modifications a licensee may make in the subject process during the term of
the license agreement becomes the property of the Company or are licensed to the
Company. Should a licensee fail to meet its

                                       4



royalty obligations or other material obligations, the Company may terminate the
license. Many licensees (including the domestic licensees), upon prior notice to
the Company, may also terminate the license for any reason. The Company may vary
the agreement used with new licensees according to prevailing conditions.

         The Company acts as licensor under arrangements relating to the use of
the Thermopipe Process in the United Kingdom and elsewhere on a non-exclusive
basis.

         Insituform East, Incorporated ("East") holds six sub-licenses to the
Insituform CIPP Process to operate in the states of Virginia, Delaware,
Maryland, Pennsylvania, Ohio, a portion of Kentucky, West Virginia and the
District of Columbia under the Company's exclusive license to the Insituform
CIPP Process for the entire United States. (The United States rights to the
Insituform CIPP Process are owned by the Company's subsidiary, Insituform
(Netherlands) B.V. ("Insituform Netherlands")). Pursuant to a July 1999
settlement agreement with East and several affiliates of East (the "Settlement
Agreement"), Midsouth Partners, an affiliate of East, retains a limited,
non-exclusive right in Midsouth Partners' former territory to utilize the
Insituform CIPP Process and technology in the condition and state as
commercially practiced on the date of settlement.

         As previously reported by the Company, the Company and Insituform
Netherlands initiated litigation against East and Midsouth Partners in Federal
District Court for the Middle District of Tennessee (Civil Action No. 3-99-1130)
and filed an Amended Complaint on June 13, 2000, alleging among other matters,
trademark violations and a non-curable breach of the Settlement Agreement; and,
seeking: (i) the right to terminate the grant of the limited license to Midsouth
Partners under the Settlement Agreement; (ii) the affirmation of East's
obligations to make royalty payments and cross-over royalty payments on work
performed by East or any of its affiliates within the scope of the subject
matter of East's sub-licenses outside East's licensed territories under East's
sub-licenses; and (iii) a declaration that the Company is not obligated to
continue payment of certain finder's fees to East. The court issued a
preliminary bench ruling on February 22, 2002 in favor of the Company on point
(ii), except with respect to Midsouth Partners, and in favor of the Company on
point (iii). The court ruled against the Company on point (i), finding that
Midsouth Partners had not committed a material breach of the Settlement
Agreement, nor had Midsouth Partners committed violations permitting
termination. After issuance of a final ruling from the court affirming the
preliminary findings, the parties agreed not to appeal the ruling and to
conclude the litigation.

OWNERSHIP INTERESTS IN OPERATING LICENSEES AND PROJECT JOINT VENTURES

         The Company, through its subsidiary, Insituform Holdings (UK) Limited,
holds one-half of the equity interest in Insituform Rohrsanierungstechniken
GmbH, the Company's licensee of the Insituform CIPP Process and the NuPipe
Process in Germany. The remaining interest is held by Per Aarsleff A/S, a Danish
contractor ("Per Aarsleff"). The joint venture partners have
rights-of-first-refusal in the event either party determines to divest its
interest.

         The Company, through its subsidiary, INA Acquisition Corp., holds
one-half of the equity interest in Italcontrolli-Insituform S.r.l., the
Company's licensee of the Insituform CIPP Process in Italy. The remaining
interest is held by Per Aarsleff. The joint venture partners have
rights-of-first-refusal in the event either party determines to divest its
interest.

         The Company holds a 49% joint venture interest in Ka-Te Insituform
A.G., the Company's licensee of the Insituform CIPP Process in Switzerland,
Liechtenstein and Voralberg, Austria. The remaining interest is held by Ka-Te

venture.

                                       5



         The Company has entered into several contractual joint ventures in
order to develop joint bids on contracts for its pipeline rehabilitation
business, and for tunneling operations. Typically, the joint venture entity
holds the contract with the owner and subcontracts portions of the work to the
joint venture partners. As part of the subcontracts, the partners usually
provide bonds to the joint venture. The Company could be required to complete
its joint venture partner's portion of the contract if the partner is unable to
complete its portion and a bond is not available. The Company continues to
investigate opportunities for expanding its business through such arrangements.

MARKETING

         The marketing of the Company's rehabilitation technologies is focused
primarily on the municipal wastewater markets worldwide, which the Company
expects to remain the largest part of its business for the foreseeable future.
To help shape decision-making at every step, the Company uses a multi-level
sales force structured around target markets and key accounts, focusing on
engineers, consultants, administrators, technical staff and elected officials.
The Company also produces sales literature and presentations, participates in
trade shows, conducts national advertising and executes other marketing programs
for the Company's own sales force and those of unaffiliated licensees. The
Company's unaffiliated licensees are responsible for marketing and sales
activities in their respective territories. See "Licensees" above for a
description of the Company's licensing operations and for a description of
investments in licensees.

         The Company offers its TiteLiner Process worldwide to line new and
existing steel pipelines.

         The Company bids on tunneling projects in selected geographical markets
in the United States.

         No customer accounted for more than 10% of the Company's consolidated
revenues during the years ended December 31, 2002, 2001 and 2000, respectively.

* Beginning in 2003, the Company is implementing more strict criteria for the
  recording of an order and its inclusion in backlog. To enable future
  comparability, backlog results at December 31, 2001 and 2002 have been revised
  from results previously communicated. As a result of this change, at December
  31, 2001, the combined apparent low bid and unreleased term expected in the
  next 12 months was reduced by $16.0 million and apparent low bid and
  unreleased term available beyond 12 months was reduced by $17.7 million.
  Backlog at December 31, 2002 was reduced by $31.7 million from the amount
  previously communicated.

         Contract backlog is management's expectation of revenues to be
generated from received, signed, uncompleted contracts whose cancellation is not
anticipated at the time of reporting. Reported contract backlog excludes any
term contract amounts for which there is not specific and determinable work
released. At December 31, 2002, the Company's 2003 contract backlog (excluding
projects where the Company has been advised that it is the low bidder, but not
formally awarded the contract) was approximately $227.2 million, which
represents an increase of $62.9 million from the 2002 contract backlog reported
at December 31, 2001. With the exception of tunneling, the Company anticipates
that substantially all contract backlog recorded at December 31, 2002 and an
additional $61.5 million of unreleased term contracts and jobs on which the
Company is the apparent low bidder will be completed in 2003. Tunneling contract
backlog at December 31, 2002 includes an estimated $30.0 million available
beyond 2003. The Company estimates that a further $20.9 million of unreleased
term contracts and jobs on which the Company is the apparent low bidder will be
available beyond 2003. Backlog estimates beyond one year are inherently subject
to greater uncertainty due to their long-term nature. The Company estimated that
at December 31, 2001, $193.1 million of unreleased term contracts and jobs on
which the Company was the apparent low bidder would be available in 2003 and
beyond. See the following discussion of backlog adjustments occurring during
2002. All backlog values are the estimate of management based on contracts
outstanding December 31, 2002 and are subject to change due to factors beyond
the control of the Company, such as modification or cancellation of the contract
award. See "Forward-Looking Information" discussion in Item 7.

         The Company previously announced that up to $98.6 million of total
recorded backlog associated with the Jacksonville Electric Authority ("JEA")
term contract was potentially at risk. The five-year JEA term contract was
awarded to PM Construction & Rehabilitation, L.P. and Kinsel Industries, Inc., a
Joint Venture (the "Joint Venture") in November 2000, for a not to exceed amount
of $380 million. In the third quarter of 2002, JEA informed the Company that
while they do not plan to cancel the contract, they intended to release $20
million to the Joint Venture in 2002 with the remainder of the work being sent
to bid. The impact was a reduction in unreleased backlog of $98.2 million during
the third quarter of 2002. The contract calls for a minimum of 150,000 feet
installed per year or the Company will receive pay for downtime. The Company
estimates this to be the equivalent of approximately $20 million per year, of
which the Company's interest is approximately $10 million. JEA has not changed
the "not to exceed amount" under the contract. As a result, the Company adjusted
reported backlog as of December 31, 2002 to reflect only the contract minimums
of $25.6 million for the Company's portion of work expected during the remaining
contract term. The Company has included $10 million of the expected remaining
work in

                                       7


apparent low bid and unreleased term expected in the next 12 months; the
remaining $15.6 million is expected beyond 2003.

PRODUCT DEVELOPMENT

         The Company, by utilizing its own laboratories and test facilities as
well as outside consulting organizations and academic institutions, continues to
develop improvements to its proprietary processes, including the materials used
and the methods of manufacturing and installing pipe. During the years ended
December 31, 2002, 2001 and 2000, the Company spent approximately $2.0 million,
$2.3 million and $2.4 million, respectively, on research and development
activities.

MANUFACTURING AND SUPPLIERS

         The Company maintains its principal North American Insituform CIPP
Process liner manufacturing facility in Batesville, Mississippi, with an
additional facility located in Memphis, Tennessee. The Company is in the process
of evaluating various alternatives regarding modifications, upgrades and
revisions to its manufacturing facilities and will likely incur costs of up to
$5.6 million for these matters as part of its 2003 planned capital expenditures.
In Europe, Insituform Linings Plc ("Linings"), a majority-owned subsidiary,
manufactures and sells Insituform CIPP Process liners from its plant located in
Wellingborough, United Kingdom. The Company holds a 75% interest in Linings and
Per Aarsleff the remainder, which interests are subject to rights of first
refusal held by the Company and Per Aarsleff in the event of any proposed
disposition.

         Although raw materials used in the Company's Insituform CIPP Process
products are typically available from multiple sources, the Company's historical
practice has been to purchase materials from a limited number of suppliers. The
Company maintains its own felt manufacturing facility at its Insitutube(R)
manufacturing facility in Batesville, and purchases substantially all of its
fiber requirements from one source, alternate vendors of which the Company
believes are readily available. Although the Company has worked with one vendor
to develop a uniform and standard resin to source substantially all of its resin
requirements in North America, the Company believes that resins are also readily
available from a number of major companies should there be a need for
alternative resin sourcing. The Company believes that the sources of supply in
connection with its Insituform CIPP Process operations are adequate for its
needs.

         The Company has investigated various alternatives, but does not
currently have, a manufacturing source for its NuPipe Process thermoplastic
pipe. Because of its inventory level of NuPipe Process thermoplastic pipe and
because the Company has not recently entered into NuPipe Process installation
contracts and it is not required to supply thermoplastic pipe to its NuPipe
licensees, the Company has not been materially adversely affected by not having
a manufacturing source for thermoplastic pipe. If the demand for NuPipe Process
products increases, the Company will qualify a new manufacturing source or
manufacture NuPipe Process thermoplastic pipe itself. See further discussion
under "Patents and Licenses" below.

         The Company has received a contractual commitment from the provider for
the manufacture and supply of Thermopipe Process products to the Company through
2004.

         The Company sells Insituform CIPP Process liners and related products
to certain licensees pursuant to fixed-term supply contracts. Under the
arrangements assumed in connection with the acquisition of the Thermopipe
Process, the Company also furnishes Thermopipe Process products to its approved
contractors and licensees.

                                       8


         The Company manufactures certain equipment used in its corrosion and
abrasion protection operations.

PATENTS AND LICENSES

         As of December 31, 2002, the Company held 65 patents in the United
States relating to the Insituform CIPP Process, the last of which to expire will
remain in effect until 2017. As of December 31, 2002, the Company had 10 patents
pending in the United States that relate to the Insituform CIPP Process.

         The Company has obtained patent protection in its principal overseas
markets covering various aspects of the Insituform CIPP Process. The
specifications and/or rights granted in relation to each patent will vary from
jurisdiction to jurisdiction. In addition, as a result of differences in the
nature of the work performed and in the climate of the countries in which the
work is carried out, not every licensee uses each patent, and the Company does
not necessarily seek patent protection for all of its inventions in every
jurisdiction in which it does business.

         There can be no assurance that the validity of the Company's patents
will not be successfully challenged. The Company's business could be adversely
affected by increased competition upon expiration of the patents or if one or
more of its Insituform CIPP Process patents were adjudicated to be invalid or
inadequate in scope to protect the Company's operations. The Company believes,
however, that, in either case, its long experience with the Insituform CIPP
Process, its continued commitment to support and develop the Insituform CIPP
Process, the strength of its trademarks, and its degree of market penetration,
should enable the Company to continue to compete effectively in the pipeline
rehabilitation market.

         The Company holds 12 patents issued in the United States covering
either the NuPipe Process or materials used in connection with the NuPipe
Process. The Company also holds similar NuPipe Process (or related material)
patents in 14 other countries. Due to reduced installation volumes and current
lack of a supplier for NuPipe during 2002, the Company reduced the carrying
value of its NuPipe patents and licenses in accordance with SFAS 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets," which the
Company early adopted in 2001. The NuPipe Process entails the manufacture of a
folded thermoplastic replacement pipe that is stored on a reel in a reduced
shape. The pipe is heated at the installation site to make it flexible enough to
be inserted into an existing conduit. It is then pulled into place and
sequentially expanded to match the existing conduit by internal heat and
pressure and by progressive rounding, creating a tight fit against the conduit
being repaired.

         The Company holds two patents issued in the United States and 10
patents outside of the United States relating to the Thermopipe Process for
rehabilitating potable water and other aqueous fluid pipes.

         Even though the Company holds a few patents relating to its corrosion
and abrasion protection business, the Company believes that the success of its
TiteLiner Process business, operated through its United Pipeline Systems
division, depends primarily upon its proprietary know-how and its marketing and
sales skills.

         The Company holds the exclusive rights to use the patents, trademarks
and know-how related to the Paltem-HL system, a process for rehabilitating
pressure pipes, which includes the Paltem-Frepp system, for substantially all of
North America and, on a non-exclusive basis, additional territories in the
eastern hemisphere and Latin America. Under the license, the Company is required
to pay royalties at specified rates on installations and sales of liners. During
the year ended December 31, 2002, the Company did not have any operations under
this license.

                                       9

         The Company's pipebursting operations are performed under
royalty-bearing, non-exclusive licenses from BG Plc. The licenses terminate upon
expiration of the underlying patent, which expires on April 19, 2005. In
addition, either party may terminate the license upon six months' notice and
under certain other circumstances. In 2002, the Company paid $1.1 million to BG
Plc. under the license.

COMPETITION

         The markets in which the Company operates are highly competitive. Most
of the Company's products, including the Insituform CIPP Process, face direct
competition from competitors offering similar or equivalent products or
services. In addition, clients can select a variety of methods to meet their
pipe installation and rehabilitation needs, including a number of methods the
Company does not offer.

         Most of the Company's installation operations are either
project-oriented or term contracts for governmental entities that are obtained
through competitive bidding or negotiations. Most competitors are local or
regional companies, and may be either specialty trenchless contractors or
general contractors. A few competitors have far greater financial resources than
the Company and, with regard to products other than the cured-in-place process,
may have greater experience than the Company. Therefore, there can be no
assurance as to the success of the Company's trenchless processes in competition
with these companies and alternative technologies for pipeline rehabilitation.

SEASONALITY

         The Company's operations can be affected by severe weather. The effects
of weather are most notable between quarters of any given year. Typically, the
summer months yield the strongest operational results, while the first quarter
is normally more weak due to weather. Unusually severe weather in any area with
a large project, or a significant number of smaller jobs, can cause short-term
anomalies in operational performance. Only the tunneling segment is relatively
immune to weather induced variability in operating results. For the past five
years seasonal variation in work performed has not had a material effect on the
Company's consolidated results of operations.

EMPLOYEES

         As of December 31, 2002, the Company employed 1,938 individuals.
Certain of the Company's contracting operations are parties to collective
bargaining agreements covering an aggregate of 391 employees. The Company
generally considers its relations with its employees to be good.

GOVERNMENT REGULATION

         The Company is required to comply with all applicable United States
federal, state and local, and all foreign, statutes, regulations and ordinances.
In addition, the Company's installation and other operations have to comply with
various relevant occupational safety and health regulations, transportation
regulations, code specifications, permit requirements, and bonding and insurance
requirements, as well as with fire regulations relating to the storage, handling
and transporting of flammable materials. The Company's manufacturing facilities,
as well as its installation operations, are subject to state and national
environmental protection regulations, none of which presently have any material
effect on the Company's capital expenditures, earnings or competitive position
in connection with the Company's present business. However, although the
Company's installation operations have established monitoring programs and
safety procedures relating to its installation activities and to the use of
solvents, further restrictions could be imposed on the manner in which
installation activities are conducted, on equipment used in installation
activities and on the use of solvents or the thermosetting resins used in the
Insituform CIPP Process.

                                       10

The Company believes that it is in material compliance with environmental and
safety laws and regulations applicable to it.

         The use of both thermoplastics and thermosetting resin materials in
contact with drinking water is strictly regulated in most countries. In the
United States, a consortium led by NSF International ("NSF"), under arrangements
with the United States Environmental Protection Agency (the "EPA"), establishes
minimum requirements for the control of potential human health effects from
substances added indirectly to water via contact with treatment, storage,
transmission and distribution system components, by defining the maximum
permissible concentration of materials which may be leached from such components
into drinking water, and methods for testing them. In February 1996, the
Paltem-HL and Frepp processes under license from Ashimori were certified by the
NSF for use in drinking water systems. In April 1997, the Insituform PPL(R)
liner was certified by the NSF for use in drinking water systems, followed in
April 1999 by NSF certification of the Insituform RPP(R) liner for such use. The
Thermopipe product also has NSF approval. The NSF assumes no liability for use
of any products, and the NSF's arrangements with the EPA do not constitute the
EPA's endorsement of the NSF, the NSF's policies or its standards. Dedicated
equipment is needed in connection with use of these products in drinking water
applications. The Company does not expect material revenues from drinking water
rehabilitation at least through 2003.

Item 2. Properties

         The Company's executive offices are located in Chesterfield, Missouri,
a suburb of St. Louis, at 702 Spirit 40 Park Drive. The executive offices are
leased from an unaffiliated party through May 31, 2003. The Company is
considering the options available to it following expiration of the lease,
including a potential move to other facilities owned by the Company, also
located in Chesterfield. The Company owns its research and development facility
and its training facility in Chesterfield.

         The Company owns a liner fabrication facility and a contiguous felt
manufacturing facility in Batesville, Mississippi. The Company's manufacturing
facility in Memphis, Tennessee, is located on land sub-leased from an
unaffiliated entity for an initial term of 40 years expiring on December 31,
2020. Linings (a majority-owned subsidiary) owns certain premises in
Wellingborough, England, where its liner manufacturing facility is located.

         The Company owns or leases various operational facilities in the United
States, Canada, Europe and Latin America.

         The foregoing facilities are regarded by management as adequate for the
current requirements of the Company's business.

Item 3. Legal Proceedings

         In January 2003, the Company received notice of multiple claims,
totaling more than $3.5 million, from the buyer of the former Kinsel wastewater
treatment division. The claims arise out of the February 2002 sale of the Kinsel
wastewater treatment division and allege the valuation of the assets sold was
overstated. No litigation has been commenced. The Company is investigating the
factual basis for these claims.

         The Company is involved in certain litigation incidental to the conduct
of its business and affairs. Management does not believe that the outcome of any
such litigation will have a material adverse effect on the financial condition,
results of operations or liquidity of the Company. See "Item 1. Business -
Rehabilitation Activities."

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

GENERAL

         Insituform Technologies' revenues are derived primarily from
installation of pipeline liners, replacement pipes and other contracting
activities. Revenues are generated by the Company and its subsidiaries operating
in the United States, Canada, France, the United Kingdom, the Netherlands,
Belgium, Spain and Chile, and include royalties from unaffiliated licensees and
sub-licensees. During the three years ended December 31, 2002, 2001 and 2000,
approximately 65.5%, 69.8% and 74.0%, respectively, of the Company's
consolidated revenues related to the Insituform CIPP Process.

         The Company has three principal operating segments: rehabilitation,
tunneling and TiteLiner. The segments were determined based upon the types of
products sold by each segment and each is regularly reviewed and evaluated
separately. See Note 15 to the Consolidated Financial Statements for additional
segment information and disclosures.

         Consolidated revenues from continuing operations were $480.4 million,
increasing 7.9% over 2001 revenues of $445.3 million due primarily to growth in
the tunneling segment with additional contributions

                                       14


from rehabilitation. Increases in rehabilitation and tunneling revenues were
partially offset by a $10.7 million decline in TiteLiner revenues. Gross profit
increased by 0.6% to $125.6 million, although gross margins decreased from 28.0%
to 26.2% in 2002 versus 2001 due to decreased gross profit margins in the
rehabilitation segment. Selling, general and administrative expenses increased
1.6% to $68.0 million in 2002 due primarily to operating the Kinsel business for
two more months in 2002 than in 2001 and the May 2002 purchase of Elmore Pipe
Jacking, Inc. operations, the combined impact being a $2.7 million increase. The
elimination of amortization expense related to goodwill beginning in 2002
positively impacted operating income. Goodwill amortization pre-tax was $6.2
million in 2001 and $3.8 million in 2000. After restructuring and intangible
asset impairment charges of $2.5 million and $3.5 million in 2002, operating
income was $50.2 million in 2002, representing an increase of 7.3% over 2001
operating income, which included a $4.1 million restructuring charge.

         Consolidated revenues of $445.3 million in 2001 represented an 8.8%
increase compared to 2000 revenues of $409.4 million due primarily to the
acquisition of Kinsel in February 2001. Lower gross profit margins at Kinsel and
a smaller gross profit margin in North American rehabilitation contributed to
lower gross profit and gross margin levels in 2001 versus 2000. Selling, general
and administrative expenses were $67.0 million, a decrease of 2.7% compared to
$68.8 million in selling, general and administrative expenses in 2000.
Amortization expense increased $1.7 million in 2001 due primarily to
amortization of goodwill related to the Kinsel acquisition. The resulting
operating income, which includes a $4.1 million restructuring charge, decreased
25.7% to $46.8 million in 2001 compared to $63.0 million in 2000.

         In the third quarter of 2002, a Company crew had an accident on a
cured-in-place pipe project in Des Moines, Iowa. Two workers died and five
workers were injured in the accident. The Company fully cooperated with Iowa's
state OSHA in the investigation of the accident as well as reviewed its own
safety procedures. Included in the estimated costs associated with the accident
are the Company's insurance policy deductible, estimated OSHA assessments, lost
productivity from the temporary shutdown of two crews and time spent by all
cured-in-place pipe process field crews in additional training. The total
financial impact of the accident was estimated to be a $0.04 loss per diluted
share in 2002.

         Rehabilitation revenues increased 2.3% to $377.7 million in 2002
compared to 2001 rehabilitation revenues of $369.2 million due to growth in
North American rehabilitation. North American rehabilitation revenues increased
approximately 3.7% over 2001 due primarily to the impact of an additional two
months of revenue from Kinsel in 2002 compared to 2001. European revenues were
relatively flat in 2002 compared to 2001, falling 1.1% to $47.9 million on weak
demand and poor project pricing, primarily in France.

         Rehabilitation revenues for 2001 increased 13.3% over 2000 primarily as
a result of incremental revenues of $47.0 million related to the Kinsel
acquisition. Excluding the Kinsel acquisition, revenues in North American
rehabilitation decreased $11.6 million or 4.1% to $269.9 million. The decrease
in North America

                                       15


was a result of delays in job releases, pricing pressures and increased
competition in several North American markets. Revenues in Europe increased $9.4
million or 24.1% to $48.4 million in 2001 compared to 2000 revenues of $39.0
million primarily as a result of growth and improvement in market conditions in
Europe.

         Gross profits for rehabilitation decreased 5.6% to $101.8 million in
2002 from $107.8 million in 2001. Gross profit margins also decreased to 26.9%
from 29.2% over the same time period. Rehabilitation margins in both North
America and Europe drove the decrease, with gross profit dollars eroding 1.6%
and 25.7% in each region, respectively. Aggressive pricing in the northeastern
United States combined with increased use of subcontractors were the primary
causes for the North American decline while pricing pressure and a weak market,
primarily in France, resulted in inefficient crew utilization and tighter
margins in the European operations.

         Gross profit margin for rehabilitation was 29.2% in 2001 versus 35.5%
in 2000. The decrease in gross profit margins was primarily a result of lower
utilization rates for work crews in North American operations, combined with
more aggressive pricing as a result of increased competition in the marketplace.
Also, operational capacity had been expanded in anticipation of revenue growth
that did not materialize in 2001. Finally, the operations acquired from Kinsel
contributed 22.1% of gross profit margin, which represents a lower margin base
than typically achieved in the historical rehabilitation segment.

         Selling, general and administrative expenses in the rehabilitation
business unit were $59.9 million in 2002, a 1.5% decrease compared to 2001
selling, general and administrative expenses of $60.8 million. Selling, general
and administrative expenses as a percentage of revenues decreased to 15.9% in
2002 from 16.5% in 2001. Although the decrease appears relatively minor,
selling, general and administrative expenses for 2002 are inclusive of incentive
compensation accruals not recognized in 2001 due to performance. Significant
improvements were achieved in Europe in 2002 where initiatives to cut overhead
intensified. Kinsel operations also experienced a decrease in selling, general
and administrative expenses in 2002 in spite of two additional months of expense
as they became more integrated into the overall cost structure of the Company.

         Selling, general and administrative expenses for the Company's
rehabilitation operations decreased 1.2% in 2001 from 2000 and to 16.5% of
revenues in 2001 from 18.9% in 2000 primarily due to a significant reduction in
incentive compensation and profit sharing expense, offset by the inclusion of
selling, general and administrative expenses related to the operations acquired
in the Kinsel acquisition. Additionally, at the time of the acquisition, the
Kinsel operations had a lower cost structure than was typical for the
rehabilitation segment.

         Amortization expense decreased to $0.7 million in 2002 from $6.7
million in 2001 due to the elimination of goodwill amortization. The increase in
amortization expense from $5.0 million in 2000 to $6.7 million in 2001 was from
increased goodwill amortization resulting from the acquisition of Kinsel.

         Rehabilitation operating income was $35.2 million in 2002, a 2.7%
decrease compared to 2001 operating income of $36.2 million. Operating income
includes $3.5 million of asset impairment charges and $2.5 million of
restructuring charges in 2002, and $4.1 million of restructuring charges in
2001. The decrease is due primarily to the 2.3 percentage point decrease in
gross margin percentage that the cessation of goodwill amortization in 2002 and
improvements in administrative overhead costs could not offset.

         Rehabilitation operating income for 2001 decreased 26.1% from 2000. The
decrease in operating income was a result of the decrease in gross profit margin
discussed above, increased amortization of goodwill related to the Kinsel
acquisition and the restructuring charge of $4.1 million recorded in 2001.

         The Company believes that cost control efforts initiated in 2002 make
it well positioned to optimize benefits from future revenue growth. The Company
plans to reduce operating activity in markets in the northeastern United States
where pricing is unsatisfactory, but will continue its practice of operating in
selected markets in regions where the operating environment is favorable. Plans
for 2003 are to focus on moderate growth and become less dependent on cost
control in order to meet margins. Research and development efforts will be
focused more on improving existing products with regard to performance and cost,
rather than the creation of new products. The Company expects to participate in
bidding for any JEA projects put out for re-bid. See the "Backlog" section for
additional information.

         Tunneling revenues increased 76.0% to $86.3 million in 2002 compared to
$49.0 million in 2001. Elmore operations, newly acquired in 2002, contributed
$20.7 million or approximately half of the total increase. The remaining
increase is a result of the Company's strategic focus on further penetrating the
tunneling market based on market opportunities recognized in 2001 and continuing
in 2002.

         Tunneling revenues for 2001 increased 4.6% compared to 2000, due
primarily to market growth, which prompted the Company to concentrate on a
growth strategy for the business unit.

         Gross profit in 2002 was $18.3 million, a 105.6% increase compared to
2001 gross profit of $8.9 million. Elmore's contribution to gross profit was
less significant than its revenue contributions. Gross profit margin increased
to 21.2% in 2002 compared to 18.1% in 2001. The margin percentage increase is
primarily a result of positive adjustments at the close out of some large jobs.

         Gross profit margin for tunneling was 18.1% in 2001 versus 19.7% in
2000 despite slightly stronger revenues. Gross profit margin decreased during
the year due to a change in mix to smaller lower margin projects from larger
higher margin projects.

         Selling, general and administrative expenses increased 82.5% to $5.7
million in 2002 compared to $3.1 million in 2001. Most of the increase was due
to the acquisition of Elmore, with the remainder from additional incentive
compensation and support costs for segment growth. Selling, general and
administrative expenses as a percent of revenue increased to 6.6% in 2002
compared to 6.4% in 2001.

         Selling, general and administrative expenses for tunneling decreased
7.2% to $3.1 million in 2001 from $3.4 million in 2000. Selling, general and
administrative expenses decreased to 6.4% of revenues from 7.2% in 2000. The
decline in selling, general and administrative expenses in total and as a
percent of revenues was due to a reduction in incentive compensation and profit
sharing expense and targeted cost reduction initiatives in 2001.

         The tunneling segment recognized amortization expense for the first
time in 2002 due to covenants not to compete acquired as part of the purchase of
Elmore.

                                       17



         Based on a refinement of certain previous estimates reflected in the
preliminary purchase price allocation for Elmore, goodwill was increased by $5.1
million during the fourth quarter of 2002. In addition to impacting goodwill,
the result of the updated estimates decreased Elmore's beginning costs and
estimated earnings in excess of billings amount by $3.9 million and increased
beginning accrued expenses by $1.3 million. If these entries had not occurred,
tunneling operating income would have been lower by $5.0 million. See Note 3 to
the Consolidated Financial Statements for additional information regarding the
acquisition of Elmore.

         Operating income was $12.2 million in 2002, a 111.4% increase over
2001 operating income of $5.7 million, which reflects the factors discussed
above.

         Tunneling operating income decreased slightly in 2001 compared to 2000,
primarily as a result of the decrease in gross profit margins discussed above.

         The Company expects the tunneling business unit to continue growing in
fiscal 2003, but at a more moderated pace than in 2002. The Affholder operations
exceeded expectation in 2002, especially at the gross profit line where lower
gross margin yields were originally expected. As tunneling operations, and more
specifically, Elmore operations, continue to develop the market and are fully
integrated into the overall consolidated structure, the Company expects
efficiency gains at both the gross margin and operating income levels in the
tunneling business unit and for tunneling to continue to grow in significance to
the Company's consolidated financial results.

         TiteLiner revenues in 2002 were $16.4 million, a 39.5% decrease from
2001 revenues due primarily to continued decreases in demand from mining
services. The Company expects the increases in oil prices in latter 2002 and
early 2003 to moderately increase the demand in Canadian operations as demand
for this product in North America typically responds to oil price changes.

         TiteLiner revenues for 2001 decreased 26.4% from 2000 primarily as a
result of the completion of a large contract in South America in early 2001
which added approximately $13.0 million to revenues in 2000 versus $1.0 million
in 2001. In addition, the United States and South American markets are geared
towards large projects related to mining and thus fluctuate in tandem with
mineral prices, especially copper. The price of copper and palladium were
depressed, which resulted in a substantial decrease in projects relating to
mining.

         Gross profit was $5.6 million in 2002, a decrease of 31.4% compared to
$8.2 million in gross profit in 2001. The decrease is almost solely based on the
lower revenues in 2002 versus 2001. Gross profit margin increased, however, in
2002 to 34.1% due primarily to the favorable impact from closing out the large
project in South America.

                                       18



         Gross profit margin for TiteLiner was 30.1% in 2001 compared to 33.6%
in 2000. Lower mineral prices led to decreased revenues during 2001 placing
pressure on overall unit capacity costs yielding lower gross profit margins.

         Selling, general and administrative expenses were $2.5 million for
TiteLiner in 2002, representing an 18.3% reduction compared to 2001 selling,
general and administrative expenses of $3.0 million. Much of this improvement
was the result of the scaling back of TiteLiner operational costs as well as a
smaller allocation of corporate overhead to the business unit given the
reduction in segment revenues. Selling, general and administrative expenses as a
percentage of revenue increased to 15.1% in 2002 from 11.2% in 2001 due to lower
revenues in 2002.

         Selling, general and administrative expenses for TiteLiner decreased
22.9% in 2001 from 2000 primarily as a result of a reduction in incentive
compensation and profit sharing expense and targeted cost reduction initiatives.
Selling, general and administrative expenses increased in 2001 to 11.2% of
revenues from 10.7% in 2000 due to decreased leverage of fixed costs over a
lower revenue base.

         Operating income for the TiteLiner business unit decreased 41.7% to
$2.8 million in 2002, compared to $4.8 million in 2001 primarily as a function
of the decreased demand experienced in the business unit over the past year.

         TiteLiner's operating income for 2001 declined 40.6% compared to 2000,
as a result of the decreases in revenues and gross profit margins previously
discussed.

         After experiencing declining demand in the TiteLiner segment in 2002,
the Company achieved its goal of maintaining, or bettering, gross profit margins
and reducing operating costs in the business unit. Thus, the impact at the
operating income line for the segment was minimized. The Company now expects
demand in the TiteLiner business unit to stabilize at or around the current rate
throughout 2003, as there were signs of moderate strength in the final months of
2002 primarily due to increasing oil and petroleum product prices to which the
demand for the TiteLiner product is sensitive.

SPECIAL CHARGES

         The Company recorded two special charges in the third quarter of 2002.
The first was a pre-tax charge of $2.5 million related to restructuring efforts.
Of this amount, $1.3 million related to the elimination of 75 positions,
primarily in administrative and overhead functions. An additional $1.2 million
related to the write-down of information technology assets, lease cancellations,
and disposal of certain identifiable fixed assets, primarily at the corporate
level. As of December 31, 2002, the remaining liability related to the
restructuring charge was $1.1 million, $0.8 million of which related to expected
future severance costs. The Company expects the annualized benefit from this
restructuring to be approximately $8.2 million before tax.

         In the fourth quarter of 2001, the Company recorded a pre-tax
restructuring charge of $4.1 million, $0.9 million of which related to the
elimination of 112 company-wide positions specifically identified as of December
31, 2001. An additional $3.2 million of the charge related to asset write-downs,
lease cancellations and other costs associated with the closure and
consolidation of eight facilities in the United States and the disposal of the
associated assets. The anticipated annualized pre-tax benefit of this
restructuring effort is $9.0 million. See Note 5 to the Consolidated Financial
Statements regarding restructuring costs.

         The Company also took a charge in the third quarter of 2002 related to
a write-down of intangible assets. The pre-tax charge totaled $3.5 million and
related primarily to patents, trademarks, license and

                                       19



non-compete intellectual property assets that the Company deemed to be impaired
based on recent business decisions and other circumstances. The asset write-down
is expected to reduce amortization expense by approximately $0.5 million
annually before tax. The impairment analysis was conducted in accordance with
SFAS 144, "Accounting for the Disposal of Long-Lived Assets," which the Company
early adopted in 2001. See Note 6 to the Consolidated Financial Statements
regarding intangible asset impairment.

The Company is performing a strategic analysis on some facilities in the United
States. Depending on the outcome of these evaluations, a further charge could be
taken during 2003.

OTHER INCOME/EXPENSE

         Interest expense was $7.9 million in 2002, a 15.3% decrease compared to
2001 interest expense of $9.3 million. The decrease is primarily a result of a
reduction in borrowing levels in 2002 and lower variable interest rates attached
to short-term borrowings.

         Interest expense for 2001 compared to 2000 was relatively unchanged at
$9.3 million. Although the Company made a scheduled $15.7 million payment on its
Senior Notes, Series A (the "Senior Notes") in February 2001, the Company
incurred additional debt of $12.2 million in the first quarter of 2001 as part
of its acquisition of Kinsel.

         Other income increased 32.3% to $3.1 million in 2002 primarily due to
the $1.2 million gain on the sale of a real estate investment acquired with
Kinsel. This represents a $0.8 million increase over other income of $2.3
million in 2001. Interest income decreased $0.3 million on lower interest rates
on cash during 2002 compared to 2001. In 2001, other income decreased 38.1%, or
$1.4 million, to $2.3 million from $3.7 million in 2000. This was primarily due
to a decline of four percentage points in market rates of return on the
Company's short-term investments.

INCOME TAXES

         The Company's effective tax rate for 2002 decreased to 38.5% compared
to 39.4% in 2001. This was primarily due to the Company's adoption of SFAS 142
as detailed in Note 8 to the Consolidated Financial Statements. This statement
provides that goodwill should not be amortized but shall be tested for
impairment annually, or more frequently, if circumstances indicate potential
impairment. Management determined that there was no impairment to goodwill as of
December 31, 2002 and therefore, no expense for goodwill through amortization or
otherwise was recorded in 2002 for financial reporting purposes. The favorable
effect on the rate as a result of the adoption of SFAS 142 was offset to some
extent by a potential non-deductible OSHA penalty in relation to an Iowa job
site accident.

         The Company's effective tax rate was 39.4% in 2001 compared to 39.5% in
2000. This minor change was the result of two offsetting components. There was
an increased effect of non-deductible goodwill as a result of the Kinsel
acquisition which was offset by a reduction due to the favorable conclusion of
outstanding tax examinations.

         The effective tax rate was calculated consistent with the Company's
belief that deferred tax assets will be fully realized in future periods. See
Note 12 to the Consolidated Financial Statements regarding taxes on income.


                                       20



MINORITY INTEREST AND EQUITY IN EARNINGS OF AFFILIATED COMPANIES

         Minority interest in net income was $0.2 million in 2002, a 45.1%
decrease from 2001 minority interest in net income of $0.3 million. Equity in
earnings of affiliated companies decreased 26.3% to $0.8 million in 2002
compared to $1.1 million in 2001. The decrease primarily resulted from the
discontinued affiliation with a joint venture partner in the third quarter of
2002.

         Minority interest in net income decreased in 2001 to $0.3 million from
$0.6 million in 2000. The decrease was due to the acquisition in 2001 of an
additional 10% interest in Video Injection, and, in late 2000, the purchase of
an additional 35% interest in Insituform France. Equity in earnings of
affiliated companies increased 39.2% to $1.1 million in 2001 compared to $0.8
million in 2000.

DISCONTINUED OPERATIONS

         During the fourth quarter of 2001, the Company made the decision to
sell certain operations related to the Kinsel acquisition. At that time, the
Company classified as discontinued the wastewater treatment plant, commercial
construction and highway operations. For the 2002 fiscal year, discontinued
operations generated a $5.9 million net loss. Although all of these operations
were disposed of in 2002, under the terms of sale, the Company is still
responsible for certain identified jobs. The few remaining jobs in process at
December 31, 2002 are expected to be completed in 2003. See Note 16 to the
Consolidated Financial Statements regarding subsequent events.

         The Company completed the sale of the wastewater treatment plant
construction operations effective January 1, 2002. The Company received $1.5
million in cash and a $2.0 million note for a total sale price of $3.5 million,
resulting in a slight loss on the sale. In the first quarter of 2003, the
Company received claims by the buyer of the wastewater treatment plant
operations. See Note 16 to the Consolidated Financial Statements regarding
subsequent events.

         During the third quarter of 2002, the Company sold the heavy highway
operations for $2.6 million in cash and $1.5 million in notes, resulting in a
pre-tax gain of $1.5 million, or $0.9 million after-tax.

         The Company completed the sale of certain contracts and assets of the
highway maintenance operations during the fourth quarter of 2002 for $1.4
million in cash and $1.5 million in subordinated notes. The Company recognized
no gain or loss on this sale.

         The Company has assessed the valuation of amounts receivable in
connection with these disposed operations and established appropriate reserves.
Based on the expected reduction in net proceeds reflected by these reserves, the
total after-tax gain on sale from these operations would have been $0.6 million.
These sales comprised the disposition of all operations previously classified as
discontinued. See Note 4 to the Consolidated Financial Statements for additional
disclosure of discontinued operations.

NET INCOME/EARNINGS PER SHARE

         Net income declined by 8.8% in 2002 to $22.7 million from $24.9 million
in 2001. Net income in 2001 had decreased 28.8% from 2000 net income of $34.9
million. Return on revenue decreased in each of the last three years from 8.5%
in 2000 to 5.6% in 2001 and 4.7% in 2002. Return on average stockholders' equity
was 8.7%, 12.0%, and 23.0% in 2002, 2001, and 2000, respectively. The results
include $5.9 million and $0.1 million in losses from discontinued operations in
2002 and 2001, respectively. These results also include the impact of a $2.5
million restructuring charge and $3.5 million intangible asset write-down in
2002 and a $4.1 million restructuring charge in 2001, all amounts before tax.
There were no comparable charges in 2000.

                                       21


         Diluted earnings per share were $0.85 for 2002, down 7.6% compared to
2001 diluted earnings per share of $0.92. The restructuring charge and
impairment charge in 2002 impacted diluted earnings per share by $0.06 and $0.08
per share respectively. Discontinued operations adversely impacted diluted
earnings per share in 2002 by $0.22 per share.

         Diluted earnings per share decreased 32.8% from $1.37 per share in 2000
to $0.92 per share in 2001. The restructuring charge and the effect of
discontinued operations discussed above impacted diluted earnings per share by
$0.10 per share. Diluted earnings per share were also favorably impacted by the
repurchase of 249,500 shares of common stock in 2002 and 563,109 shares of
common stock in 2001.

OUTLOOK

         During 2002, management primarily focused on maintaining revenues with
a more cost efficient infrastructure supporting the Company's operations.
Management believes that the implementation of these cost reduction programs
will better position the Company to take advantage of positive market conditions
when the economy rebounds. Backlog remains strong in most business units and
growth in the tunneling segment is expected to continue fueling overall moderate
growth of the Company. Rehabilitation is expected to continue revenue growth at
a slightly higher rate in 2003 compared to 2002 with the potential for some
erosion of gross margin.

         The Company expects the overall sales environment to remain challenging
with regard to bidding and pricing. The impact, if any, of the war with Iraq is
uncertain, although the current political situation could potentially disrupt
and further soften the market for municipal contracts.

CRITICAL ACCOUNTING POLICIES

         Discussion and analysis of the Company's financial condition and
results of operations are based upon the Company's consolidated financial
statements, which have been prepared in accordance with accounting principles
generally accepted in the United States. The preparation of these financial
statements requires the Company  to make estimates and judgments that affect the
reported amount of assets and liabilities, revenues and expenses, and related
disclosure of contingent assets and liabilities at the financial statements
date. Actual results may differ from these estimates under different assumptions
or conditions.

         Some accounting policies require the application of significant
judgment by management in selecting the appropriate assumptions for calculating
financial estimates. By their nature, these judgments are subject to an inherent
degree of uncertainty. The Company believes that its critical accounting
policies are limited to those described below. For a detailed discussion on the
application of these and other accounting policies, see Note 2 to the
Consolidated Financial Statements.

REVENUE RECOGNITION - PERCENTAGE-OF-COMPLETION METHOD

         The Company recognizes revenues and profit as construction and
installation contracts progress using the percentage-of-completion method of
accounting, which relies on estimates of total expected contract revenues and
costs. Under this method, estimated contract revenues and resulting gross profit
margin are recognized based on actual costs incurred to date as a percentage of
total estimated costs. The Company follows this method since reasonably
dependable estimates of the revenues and costs applicable to various elements of
a contract can be made. Since the financial reporting of these contracts depends
on estimates, which are assessed continually during the term of these contracts,
recognized revenues and profit are subject to revisions as the contract
progresses to completion. Total estimated costs, and thus contract

                                       22


margin, are impacted by changes in productivity, scheduling, and the unit cost
of labor, subcontracts, materials and equipment. Additionally, external factors
such as weather, customer needs, customer delays in providing approvals, labor
availability, governmental regulation and politics, may also affect the progress
and estimated cost of a project's completion and thus the timing of margin and
revenue recognition. Revisions in profit estimates are reflected in the period
in which the facts that give rise to the revision become known. Accordingly,
favorable changes in estimates result in additional revenues and profit
recognition, and unfavorable changes in estimates result in a reduction of
recognized revenues and profits. When current estimates of total contract costs
indicate that the contract will result in a loss, the projected loss is
recognized in full in the period in which the loss becomes evident. Revenues
from change orders, extra work, variations in the scope of work and claims are
recognized when realization is reasonably assured.

         Many of the Company's contracts provide for termination of the contract
at the convenience of the customer. In the event a contract would be terminated
at the convenience of the customer prior to completion, the Company will
typically be compensated for progress up to the time of termination and any
termination costs. In addition, many contracts are subject to certain completion
schedule requirements with liquidated damages in the event schedules are not met
as the result of circumstances that are within the Company's control. Losses on
terminated contracts and liquidated damages have historically not been
significant.

RETAINAGE

         Many of the contracts under which the Company performs work contain
retainage provisions. Retainage refers to that portion of revenue earned by the
Company but held for payment by the customer pending satisfactory completion of
the project. Unless reserved, the Company assumes that all amounts retained by
customers under such provisions are fully collectible. Historically, the Company
has not experienced any material write-offs of retainage receivables. Retainage
on active contracts is classified as a current asset regardless of the term of
the contract. See Note 2 to the Consolidated Financial Statements regarding
classification of current assets and current liabilities.

GOODWILL IMPAIRMENT

         Under Statement of Financial Accounting Standards No. 142, "Goodwill
and Other Intangible Assets" (SFAS 142), the Company assesses recoverability of
goodwill on an annual basis or when events or changes in circumstances indicate
that the carrying amount of goodwill may not be recoverable. Factors that could
potentially trigger an impairment review include the following:

         -        significant underperformance of a segment or division relative
                  to expected historical or projected future operating results;

         -        significant negative industry or economic trends; and

         -        significant changes in the strategy for a segment or division.

         In accordance with the provisions of SFAS 142, the Company calculates
the fair value of its reporting units and compares such fair value to the
carrying value of the reporting unit to determine if there is any indication of
goodwill impairment. The Company's reporting units consist of North American
rehabilitation, European rehabilitation, tunneling, and TiteLiner. To calculate
reporting unit fair value, the Company utilizes a discounted cash flow analysis
based upon, among other things, certain assumptions about expected future
operating performance. The Company typically engages a third-party valuation
expert to assist in estimating reporting unit fair value. Estimates of
discounted cash flows may differ from actual cash flows due to, among other
things, changes in economic conditions, changes to business models, changes in
the Company's weighted average cost of capital, or changes in operating
performance. An

                                       23


impairment charge will be recognized to the extent that the implied fair value
of the goodwill balances for each reporting unit is less than the related
carrying value.

DEFERRED INCOME TAX ASSETS

         The Company provides for estimated income taxes payable or refundable
on current year income tax returns as well as the estimated future tax effects
attributable to temporary differences and carryforwards, in accordance with the
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" ("SFAS 109"). SFAS 109 also requires that a valuation allowance be
recorded against any deferred tax assets that are not likely to be realized in
the future. This requires considerable judgment on the part of management to
determine such realizability. The determination is based on the ability of the
Company to generate future taxable income and, at times, is dependent on
management's ability to implement strategic tax initiatives to ensure full
utilization of recorded deferred tax assets. Should management not be able to
implement the necessary tax strategies, the Company may need to record valuation
allowances for certain deferred tax assets, including those related to foreign
income tax benefits.

LONG-LIVED ASSETS

         Property, plant and equipment, goodwill and other intangibles
(primarily patents and covenants not to compete) are recorded at cost and,
except for goodwill, are amortized on a straight-line basis over their estimated
useful lives. Changes in circumstances such as technological advances, changes
to the Company's business model or changes in the Company's capital strategy can
result in the actual useful lives differing from the Company's estimates. In
those cases where the Company determines that the useful life of property, plant
and equipment or its intangible assets should be shortened, the Company would
depreciate the net book value in excess of the salvage value over its revised
remaining useful life, thereby increasing depreciation expense.

         Long-lived assets, including property, plant and equipment, and other
intangibles, are reviewed by the Company for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Factors the Company considers important which could trigger an
impairment review include the following:

         -        significant underperformance in a region relative to expected
                  historical or projected future operating results;

         -        significant changes in the use of the assets of a region or
                  the strategy for the region;

         -        significant negative industry or economic trends;

         -        significant decline in the Company's stock price for a
                  sustained period; and

         -        market capitalization is significantly less than net book
                  value.

         Such impairment tests are based on a comparison of undiscounted cash
flows to the recorded value of the asset. The estimate of cash flow is based
upon, among other things, certain assumptions about expected future operating
performance. The Company's estimates of undiscounted cash flow may differ from
actual cash flow due to, among other things, technological changes, economic
conditions, changes to its business model or changes in its operating
performance. If the sum of the undiscounted cash flows (excluding interest) is
less than the carrying value, the Company recognizes an impairment loss,
measured as the amount by which the carrying value exceeds the fair value of the
asset.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

         Management makes estimates of the uncollectibility of the Company's
accounts receivable. Management evaluates specific accounts where the Company
has information that the customer may be unwilling or unable to pay the
receivable in full. In these cases, the Company uses its judgment, based on the
best available facts and circumstances, and records a specific reserve for that
customer against amounts due in order to reduce the receivable to the amount
that is expected to be collected. The specific reserves are reevaluated and
adjusted as additional information is received that impacts the amount reserved.
After all attempts to collect the receivable have failed, the receivable is
written off against the reserve. Based on the information available, the Company
believes that the allowance for doubtful accounts as of December 31, 2002 is
adequate. However, no assurances can be given that actual write-offs will not
exceed the recorded reserve.

LIQUIDITY AND CAPITAL RESOURCES

         Cash and cash equivalents increased $0.7 million, or 1.0%, to $75.4
million at December 31, 2002 compared to $74.6 million in cash and cash
equivalents at December 31, 2001. The cash balance at the end of 2002 includes
$4.0 million of cash and cash equivalents restricted in various escrow accounts.
Continuing operations contributed $25.3 million in operating cash flow to the
Company, representing a 88.7% ratio versus income from continuing operations.
Operating cash flow comprised the most significant portion of the Company's cash
flow in the year ended December 31, 2002. Discontinued operations generated an
additional $0.9 million in operating cash flow for overall operating cash flow
of $26.2 million, down 24.8% from $34.8 million in operating cash flow for the
year ended December 31, 2001. Working capital was $124.2 million at December 31,
2002, down 10.4% from the $138.7 million in working capital at December 31,
2001. Operating cash flow has historically been the most significant contributor
to net cash flow and the Company expects this trend to continue into the
foreseeable future.

         The Company engaged in several acquisition and disposal activities that
had significant effects on cash flow. Proceeds from the sale of fixed assets
relate principally to $9.2 million received from a sale-leaseback arrangement on
a tunnel boring machine. The same amount is reflected in capital expenditures
for construction of the tunnel boring machine. Total capital expenditures used
$21.8 million in cash during 2002, a 30.9% increase when compared to $16.6
million in capital expenditures during 2001. Other than the tunnel boring
machine, capital expenditures were primarily to sustain the amount of equipment
already in place in the rehabilitation segment, and additional expenditures
necessary to fuel the growth experienced in the tunneling segment. The Company
expended $8.5 million, net of cash acquired, for the purchase of Elmore and
received $5.4 million in cash from the sale of discontinued operations.
Additionally, the Company received $1.9 million in cash for the sale of a real
estate investment that it owned.

         Financing activities used $13.4 million in cash for the year ended
December 31, 2002, an increase of 13.4% over $11.8 million in cash used for
financing activities for the year ended December 31, 2001. The most significant
use of cash was $20.9 million for the repayment of long-term debt, a majority of
which is the regular annual payment of $15.7 million on the Company's Senior
Notes, as well as the payoff of several capital leases related to operations at
Kinsel. The annual payments on the Senior Notes are scheduled to run through
2007. The Company received $2.5 million in cash for the issuance of 205,280
shares of Company stock related to option exercises. In mid-1998, the Company
authorized the repurchase of up to 2,700,000 shares of the Company's Common
Stock to be made from time to time over five years in open market transactions.
The amount and timing of purchases are dependent upon a number of factors,
including the price and availability of the Company's shares, general market
conditions and competing alternative uses of funds, and may be discontinued at
any time. In October 1999, the Company increased the original authorization by
an additional 2,000,000 shares of Common Stock through the period ending June
2003. In September 2001, the Company further increased the original
authorization by an additional

                                       25


1,000,000 shares of Common Stock. The Company expended $5.2 million to purchase
249,500 shares of treasury stock during 2002. As of December 31, 2002, the
Company had purchased 3,809,615 shares of treasury stock for a cumulative
purchase price of $72.6 million under the stock buyback plan. Option exercises
and treasury stock purchases did not have a significant impact on earnings per
share in 2002.

         Receivables were $83.0 million at December 31, 2002, down 3.7% compared
to $86.2 million at December 31, 2001. Costs and estimated earnings in excess of
billings increased 54.6% to $36.7 million in 2002 from $23.7 million in 2001
primarily as a result of the rapid growth in the tunneling business unit where
start-up costs at the beginning of large projects frequently cannot be billed
until tunneling begins. The collection of installation receivables involves
contractual provisions for retainage by the project owner, often 5% to 15% of
the contract amount, which extends the collection process. The slow review
processes often employed by the Company's municipal customers also further
prolong collection. Retainage receivables increased from $21.3 million in 2001
to $23.7 million in 2002. In the United States, retainage receivables are
generally received within one year after the completion of a contract. In
Europe, collection of retainage receivables normally extends one to two years.
The increase in net working capital during 2002 compared to 2001 was the primary
reason for the $19.4 million decrease in operating cash flow from continuing
operations in 2002 versus 2001. See Note 13 to the Consolidated Financial
Statements regarding changes in operating assets.

         The Company has entered into several contractual joint ventures in
order to develop joint bids on contracts for its installation business, and for
tunneling operations. In these cases, the Company could be required to complete
the partner's portion of the contract if the partner is unable to complete its
portion. The Company is at risk for any amounts for which the Company itself
could not complete the work and for which a third party contractor could not be
located to complete the work for the amount awarded in the contract. The Company
has not experienced material adverse results from such arrangements. The Company
continues to investigate opportunities for expanding its business through such
structures.

         At December 31, 2002, the Company had unused committed bank credit
facilities under a credit agreement (the "Credit Agreement") totaling $18.8
million. The commitment fee paid per annum by the Company is 0.2% on the
unborrowed balance. The interest rates under this facility vary and are based on
the prime rate or LIBOR. As of December 31, 2002, the rate was 2.19%.

         Effective March 27, 2003, the Company entered into a new three-year
bank revolving credit facility to replace its expiring bank credit facility.
This new facility provides the Company with borrowing capacity of up to $75
million. The quarterly commitment fee ranges from 0.2% to 0.3% per annum on the
unborrowed balance depending on the leverage ratio determined as of the last day
of the Company's preceding fiscal quarter. At the Company's option, the interest
rates will be either (i) the LIBOR plus an additional percentage that varies
from 0.75% to 1.5% depending on the leverage ratio or (ii) the higher of (a) the
prime rate or (b) the federal funds rate plus 0.50%. As of March 27, 2003, the
interest rate on the credit facility was 4.25% and the balance was $40.0
million.

         The Company's Senior Notes, due February 14, 2007, bear interest,
payable semi-annually in August and February of each year, at the rate per annum
of 7.88%. Each year, from February 2003 to February 2006, inclusive, the Company
will be required to make principal payments of $15.7 million, together with an
equivalent payment at maturity. On December 31, 2002, the principal amount of
Senior Notes outstanding was $78.6 million. The Senior Notes may be prepaid at
the Company's option, in whole or in part, at any time, together with a
make-whole premium. Upon specified change in control events each holder has the
right to require the Company to purchase its Senior Note without any premium
thereon.

         The Senior Notes and the new bank credit facility obligate the Company
to comply with certain financial ratios and restrictive covenants that, among
other things, place limitations on operations and sales

                                       26


of assets by the Company or its subsidiaries, limit the ability of the Company
to incur secured indebtedness and liens and limit the ability of subsidiaries to
incur indebtedness, and, in the event of default, limit the ability of the
Company to pay cash dividends or to redeem its capital stock. The Senior Notes
and the bank credit facility also obligate certain of the Company's domestic
subsidiaries to guaranty these obligations. The Company was in compliance with
all debt covenants at December 31, 2002.

         The Company's Euro Note, due July 7, 2006, bears interest, payable
quarterly in January, April, July, and October of each year, at the rate per
annum of 5.5%. Each year until maturity, the Company will be required to make
principal payments of $810 thousand for which currency fluctuations will have an
effect on the U.S. dollar payment amount. On December 31, 2002, the principal
amount of the Euro Note outstanding was (euro)3.2 million, or $3.4 million.

         The Company expects to place additional unsecured senior notes in the
maximum principal amount of $65 million with certain institutional investors
through a private offering made by the Company during the second quarter of
2003. The Company believes it has adequate resources and liquidity to fund
future cash requirements for working capital, capital expenditures and debt
repayments with cash generated from operations, existing cash balances,
additional short- and long-term borrowing (including the placement of the
additional senior notes) and the sale of assets. The Company anticipates that
operating cash flow will remain a significant portion of operational funding in
the foreseeable future. For additional discussion of assets financed through
operating leases and the capital commitments thereon, see Note 14 in the Notes
to Consolidated Financial Statements.

         The balance of cash and cash equivalents increased $10.5 million to
$74.6 million at December 31, 2001 compared to $64.1 million at December 31,
2000. The cash balance at the end of 2001 includes $4.3 million of cash and cash
equivalents restricted in various escrow accounts. Operating cash flow from
continuing operations of $44.7 million was 179.3% of income from continuing
operations and provided a majority of the Company's cash flow in the year ended
December 31, 2001. Net operating cash flow for the year was $34.8 million.
Historically, operating cash flow has been the largest source of available
capital, by comparison providing $42.6 million in the year ended December 31,
2000. Working capital was $138.7 million at December 31, 2001 compared to $114.5
million at December 31, 2000.

         Other significant sources of cash during 2001 were proceeds from
short-term borrowings against the line of credit of $15.0 million and proceeds
of $9.0 million from the sale of fixed assets, including a building due to the
closure of an operating site and two tunneling machines. An additional $6.1
million was contributed from the issuance of common stock upon the exercise of
options in 2001.

         Cash was used in nearly equal amounts for investing and financing
activities during 2001. Of the $16.6 million expended on capital, $6.6 million
related to two tunneling machines for which the Company initially funded
construction and were later leased back under an operating lease. The Company's
financing activities in 2001 included $20.6 million of repayments on debt
agreements, the largest of which was a $15.7 million scheduled principal payment
on the Company's Senior Notes. These payments are scheduled in equal amounts
through 2007. Repurchases under the Company's previously reported stock
repurchase program were $12.2 million for the year to acquire 563,109 shares.
The net effect of the Company's stock issuance and repurchases during 2001 did
not have a significant impact on earnings per share in 2001.

         Trade receivables, together with costs and estimated earnings in excess
of billings and retainage under construction contracts, increased 15.4%, to
$131.2 million, from $113.7 million at the end of 2000, primarily as a result of
the acquisition of Kinsel, which added $13.7 million to receivables at the end
of 2001. The collection of installation receivables involves contractual
provisions for retainage by the project owner, often 5% to 15% of the contract
amount, which extends the collection process. The slow review

                                       27


processes often employed by the Company's municipal customers also sometimes
further prolong collections. In the United States, retainage receivables are
generally received within one year after the completion of a contract.

         At December 31, 2001, the Company had unused committed bank credit
facilities under the Credit Agreement totaling $34.1 million. As of December 31,
2001, the interest rate on the facility was 4.75%. On December 31, 2001, the
principal amount of Senior Notes outstanding was $94.3 million.

         Capital expenditures in 2003 are expected to be used primarily to
maintain the current amount of equipment in service for rehabilitation and for
funding of growth needs in tunneling. The Company is in the process of
evaluating various alternatives regarding modifications, upgrades and revisions
to its manufacturing facilities. These changes could cost up to $5.6 million
during 2003. For additional discussion of assets financed through operating
leases and the capital commitments thereon, see Note 14 to the Consolidated
Financial Statements.

         In May 2002, the Company acquired Elmore, a regional provider of
trenchless tunneling, microtunneling, segmented lining and pipe jacking services
in the western United States for approximately $12.5 million. The acquisition
was funded primarily through $8.5 million in cash, the settlement of debt owed
by Elmore to the Company, and the assumption of additional liabilities.

         In February 2001, the Company acquired Kinsel, a trans-regional
provider of pipebursting and other sewer rehabilitation services, for
approximately $80.0 million. The acquisition was funded primarily through
issuance of 1,847,165 shares of the Company's common stock from treasury, cash
and the issuance of a $5.4 million note to the seller.

         In February 2000, the Company acquired the rights to the Insituform
CIPP Process and NuPipe Process for the states of New York and New Jersey,
through the purchase of all of the shares of the capital stock of Insituform
Metropolitan, Inc. and the operating assets of certain of its affiliates. At
closing, the Company paid the sellers an aggregate of $5.0 million in cash, in
addition to assuming operating liabilities of the acquired business. In July
2000, Insituform Italia s.r.l., a newly formed joint venture of the Company and
Per Aarsleff A/S, acquired Italcontrolli Nord s.r.l., the Insituform CIPP
Process licensee in Italy, for $1.2 million. During 2001, the Company acquired
the remaining 50% ownership of K-Insituform, N.V., its joint venture in Belgium,
for approximately $0.3 million, along with the remaining 33% ownership of
Insituform France, S.A., for approximately $0.8 million.

DISCLOSURE OF FINANCIAL OBLIGATIONS AND COMMERCIAL COMMITMENTS

         The Company has entered into various financial obligations and
commitments in the course of its ongoing operations and financing strategies.
Financial obligations are considered to represent known future cash payments
that the Company is required to make under existing contractual arrangements,
such as debt and lease agreements. These obligations may result from both
general financing activities as well as from commercial arrangements that are
directly supported by related revenue-producing activities. Commercial
commitments represent contingent obligations of the Company, which become
payable only if certain pre-defined events were to occur, such as funding
financial guarantees. See Note 14 to the Consolidated Financial Statements for
additional disclosure of financial obligations and commercial commitments.

         The following table provides a summary of the Company's financial
obligations and commercial commitments as of December 31, 2002 (in thousands).
This table includes cash obligations related to principal outstanding under
existing debt arrangements and operating leases.

MARKET RISK

         The Company is exposed to the effect of interest rate changes and
foreign currency fluctuations. Due to the immateriality of potential impacts
from changes in these rates, the Company does not use derivative contracts to
manage these risks.

INTEREST RATE RISK

         The fair value of the Company's cash and short-term investment
portfolio at December 31, 2002 approximated carrying value. Given the short-term
nature of these instruments, market risk, as measured by the change in fair
value resulting from a hypothetical 10% change in interest rates, is not
material.

         The Company's objectives in managing exposure to interest rate changes
are to limit the impact of interest rate changes on earnings and cash flows and
to lower overall borrowing costs. To achieve these objectives, the Company
maintains fixed rate debt as a percentage of its net debt in a percentage range
set by policy. The fair value of the Company's long-term debt, including current
maturities and the amount outstanding on the line of credit facility, was
estimated to be $118.2 million at December 31, 2002, and exceeded carrying value
by $1.8 million. Market risk was estimated as the potential increase in fair
value resulting from a hypothetical 10% decrease in the Company's debt specific
borrowing rates at December 31, 2002, or $3.9 million.

FOREIGN EXCHANGE RISK

         The Company operates subsidiaries, and is associated with licensees and
affiliates operating solely in countries outside of the United States, and in
currencies other than the U.S. dollar. Consequently, these operations are
inherently exposed to risks associated with fluctuation in the value of the
local currencies of these countries compared to the U.S. dollar. At December 31,
2002, approximately $3.5 million of financial instruments, primarily long-term
debt, were denominated principally in Euros. The effect of a hypothetical
adverse change of 10% in year-end exchange rates (a strengthening of the U.S.
dollar) is immaterial and would be largely offset by cash activity.

OFF-BALANCE SHEET ARRANGEMENTS

         The Company uses various structures for the financing of operating
equipment, including borrowing, operating and capital leases, and sale-leaseback
arrangements. All debt, including the discounted value of future minimum lease
payments under capital lease arrangements, is presented in the balance sheet.
The Company's commitments under operating lease arrangements were $44.5 million
at
                                       29


December 31, 2002. The Company also has exposure under performance guarantees
by contractual joint ventures and indemnification of its bonding agent and
licensees. However, the Company has never experienced any material adverse
effects to financial position, results of operations or cash flows relative to
these arrangements. The Company has no other off-balance sheet financing
arrangements or commitments. See Note 14 in the Notes to Consolidated Financial
Statements regarding commitments and contingencies.

EFFECTS OF TRANSACTIONS WITH RELATED AND CERTAIN OTHER PARTIES

         Affholder, Inc. ("Affholder"), the Company's wholly-owned subsidiary
that comprises a portion of the tunneling segment, leased five cranes from
A-Y-K-E Partnership as of March 15, 2003. A-Y-K-E is a partnership that is
controlled by Robert W. Affholder, the Company's Senior Executive Vice President
and a member of the Company's board of directors. During the year ended December
31, 2002, Affholder paid A-Y-K-E $600,000 pursuant to equipment leases. This
amount represents 10.4% of all lease payments made by Affholder during 2002 and
4.4% of all lease payments made by the Company in 2002. Affholder owns, or
leases under long-term operating leases with third party leasing companies,
several pieces of tunneling equipment, including cranes and tunnel boring
machines. From time to time for specific projects, Affholder will lease
additional equipment from a variety of sources, including A-Y-K-E. A-Y-K-E owns
various pieces of equipment that are used in the tunneling industry, including
cranes and tunnel boring machines. The cranes that are currently under lease are
leased under separate lease agreements on terms that are substantially similar
to, or better than, those otherwise available to Affholder in the market. The
leases are terminable upon 30 days' prior notice by either party. During 2002,
A-Y-K-E leased equipment only to Affholder. At Affholder's discretion, Affholder
may sublease the cranes to third parties and retain any profit generated from
the sublease.

                              REPORT OF MANAGEMENT

Management is responsible for the preparation, integrity and objectivity of
financial information included in this annual report. The financial statements
have been prepared in conformity with accounting principles generally accepted
in the United States.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts. Although the financial
statements reflect all available information and management's judgment and
estimates of current conditions and circumstances, and are prepared with the
assistance of specialists within and outside the Company, actual results could
differ from those estimates.

Management has established and maintains an internal control structure to
provide reasonable assurance that assets are safeguarded against loss from
unauthorized use or disposition, that the accounting records provide a reliable
basis for the preparation of financial statements and that such financial
statements are not misstated due to material fraud or error. Internal controls
include the careful selection of associates, the proper segregation of duties
and the communication and application of formal policies and procedures that are
consistent with high standards of accounting and administrative practices. An
important element of this system is an internal audit program.

Management continually reviews, modifies and improves its systems of accounting
and controls in response to changes in business conditions and operations and in
response to recommendations in the reports prepared by the independent public
accountants and internal auditors.

Management believes that it is essential for the Company to conduct its business
affairs in accordance with the highest ethical standards and in conformity with
the law. This standard is described in the Company's policies on business
conduct, which are publicized throughout the Company.

The Board of Directors, through its Audit Committee comprised of independent
directors, is responsible for overseeing that both management and the
independent accountants fulfill their respective responsibilities relative to
the financial statements. Moreover, the independent accountants have full and
free access to meet with the Audit Committee, with or without management
present, to discuss auditing or financial reporting matters.

                                   F-2



                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors
and Shareholders of
Insituform Technologies, Inc.

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, stockholders' equity and cash flows present
fairly, in all material respects, the financial position of Insituform
Technologies, Inc. and its subsidiaries at December 31, 2002 and the results of
their operations and their cash flows for the year ended December 31, 2002, in
conformity with accounting principles generally accepted in the United States of
America. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audit. We conducted our audit of these statements in
accordance with auditing standards generally accepted in the United States of
America, which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion. The consolidated financial
statements of Insituform Technologies, Inc. as of December 31, 2001, and for
each of the two years in the period ended December 31, 2001, were audited by
other independent accountants who have ceased operations. Those independent
accountants expressed an unqualified opinion on those financial statements dated
February 1, 2002, before the revision described in Note 8.

As discussed above, the consolidated financial statements of Insituform
Technologies, Inc. as of December 31, 2001, and for each of the two years in the
period ended December 31, 2001, were audited by other independent accountants
who have ceased operations. As described in Note 8, these financial statements
have been revised to include the transitional disclosures required by Financial
Accounting Standards No. 142, "Goodwill and Other Intangible Assets", which was
adopted by the Company as of January 1, 2002. We audited the transitional
disclosures described in Note 8. In our opinion, the transitional disclosures
for 2001 and 2000 in Note 8 are appropriate. However, we were not engaged to
audit, review, or apply any procedures to the 2001 or 2000 financial statements
of the Company other than with respect to such disclosures and, accordingly, we
do not express an opinion or any other form of assurance on the 2001 or 2000
consolidated financial statements taken as a whole.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

The following report is a copy of a report previously issued by Arthur Andersen
LLP and has not been reissued by Arthur Andersen LLP.

To the Board of Directors and the Shareholders of
Insituform Technologies, Inc.:

We have audited the accompanying consolidated balance sheets of Insituform
Technologies, Inc. and subsidiaries as of December 31, 2001 and 2000, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the three years in the period ended December 31, 2001. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. 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 financial statements referred to above present fairly, in
all material respects, the financial position of Insituform Technologies, Inc.
and subsidiaries as of December 31, 2001 and 2000, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 2001, in conformity with accounting principles generally accepted
in the United States.

                 INSITUFORM TECHNOLOGIES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       DESCRIPTION OF BUSINESS:

Insituform Technologies, Inc. (a Delaware corporation) and subsidiaries
(collectively, the "Company") is a worldwide provider of proprietary trenchless
technologies for the rehabilitation and improvement of sewer, water, gas and
industrial pipes. The Company's primary technology is the Insituform(R) process,
a proprietary "cured-in-place" pipeline rehabilitation process (the "Insituform
CIPP Process"). Pipebursting is a non-proprietary trenchless method of dilating
and replacing an old pipeline with a new plastic pipe. The microtunneling
process is a non-proprietary method of drilling a new tunnel from surface
operated equipment. Sliplining is a non-proprietary method used to push or pull
a new pipeline into an old one. The Company's TiteLiner ("TiteLiner") process is
a proprietary method of lining steel lines with a corrosion and abrasion
resistant pipe. The Company also engages in tunneling used in the installation
of new underground services.

2.       SUMMARY OF ACCOUNTING POLICIES:

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and
its majority-owned subsidiaries, the most significant of which includes a
75%-owned United Kingdom subsidiary, Insituform Linings Plc. and an 89.6%-owned
French subsidiary, Video Injection, S.A. For contractual joint ventures, the
Company recognizes revenue and profits on its portion of the contract. All
intercompany transactions and balances have been eliminated.

Accounting Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions 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.

Stock-Based Compensation

At December 31, 2002, the Company has two active stock-based compensation plans,
which are described in Note 10. The Company applies the recognition and
measurement principles of Accounting Principles Board (APB) Opinion No. 25,
"Accounting for Stock Issued to Employees," and related Interpretations in
accounting for those plans. No stock-based compensation expense was reflected in
the 2002, 2001, or 2000 net income as all options granted during those years had
an exercise price equal to the market value of the underlying common stock on
the date of the grant. The following table illustrates the effect on net income
and earnings per share if the Company had applied the fair value recognition
provisions of SFAS No. 123, "Accounting for Stock-Based Compensation," to
stock-based compensation (in thousands, except share data):

For SFAS 123 disclosure purposes, the weighted average fair value of stock
options is required to be based on a theoretical option-pricing model such as
the Black-Scholes method. In actuality, because the Company's employee stock
options are not traded on an exchange and are subject to vesting periods, the
disclosed fair value represents only an approximation of option value based
solely on historical performance. Beginning in 2000, the Company decided to
increase the alignment of key employee goals and shareholder objectives by
increasing the relative value of variable compensation. Recent stock market
volatility has increased the fair value of options granted. The above factors,
coupled with the Company's three-year vesting period on options, has caused an
increase in the theoretical value of stock option compensation in each of the
years presented.

Revenues

Revenues include construction and installation revenues that are recognized
using the percentage-of-completion method of accounting in the ratio of costs
incurred to estimated final costs. Contract costs include all direct material
and labor costs and those indirect costs related to contract performance, such
as indirect labor, supplies, tools and equipment costs. Since the financial
reporting of these contracts depends on estimates, which are assessed
continually during the term of these contracts, recognized revenues and profit
are subject to revisions as the contract progresses to completion. Revisions in
profit estimates are reflected in the period in which the facts that give rise
to the revision become known. When estimates indicate that a loss will be
incurred on a contract on completion, a provision for the expected loss is
recorded in the period in which the loss becomes evident. At December 31, 2002,
there are no significant provisions for expected losses on contracts. Revenue
from change orders, extra work, variations in the scope of work and claims is
recognized when realization is reasonably assured.

Research and Development

The Company expenses research and development costs as incurred. Research and
development costs of $2.0 million, $2.3 million and $2.4 million for the years
ended December 31, 2002, 2001 and 2000, respectively, are included in selling,
general and administrative expenses in the accompanying consolidated statements
of income.

Taxes on Income

The Company provides for estimated income taxes payable or refundable on current
year income tax returns as well as the estimated future tax effects attributable
to temporary differences and carryforwards, based upon enacted tax laws and tax
rates, and in accordance with Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes" (SFAS 109). SFAS 109 also requires that a
valuation allowance be recorded against any deferred tax assets that are not
likely to be realized in the future.

Earnings Per Share

Earnings per share have been calculated using the following share information:

Classification of Current Assets and Current Liabilities

The Company includes in current assets and current liabilities certain amounts
realizable and payable under construction contracts which may extend beyond one
year. The construction periods on projects undertaken by the Company generally
range from 1 to 24 months.

Cash and Cash Equivalents

The Company classifies highly liquid investments with original maturities of 90
days or less as cash equivalents. Recorded book values are reasonable estimates
of fair value for cash and cash equivalents. Restricted cash consists of
payments from certain identifiable customers placed in escrow in lieu of
retention in case of potential issues regarding future job performance by the
Company. Restricted cash is similar to retainage and is therefore classified as
a current asset, consistent with the Company's policy on retainage below. At
December 31, 2002 and 2001, restricted cash totaled $4.0 million and $4.3
million, respectively.

Retainage

Many of the contracts under which the Company performs work contain retainage
provisions. Retainage refers to that portion of revenue earned by the Company
but held for payment by the customer pending satisfactory completion of the
project. Unless reserved, the Company assumes that all amounts retained by
customers under such provisions are fully collectible. Retainage on active
contracts is classified as a current asset regardless of the term of the
contract. Retainage is normally collected within one year of the completion of a
contract, although collection can take up to two years in Europe. See Note 7
regarding costs and estimated earnings on uncompleted contracts.

Allowance for Doubtful Accounts

Management makes estimates of the uncollectibility of accounts receivable. The
Company records a reserve for specific accounts to reduce receivables, including
retainage, to the amount that is expected to be collected. The specific reserves
are reevaluated and adjusted as additional information is received. After all
attempts to collect the receivable have failed, the receivable is written off
against the reserve.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market.
Actual cost is used to value raw materials and supplies. Standard cost, which
approximates actual cost, is used to value work-in-process, finished goods and
construction materials. Standard cost includes direct labor, raw materials, and
manufacturing overhead based on practical capacity.

Long-Lived Assets

Property, plant and equipment, and other intangibles are recorded at cost and
are amortized on a straight-line basis over their estimated useful lives.
Intangible assets are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Such impairment tests are based on a comparison of undiscounted
cash flows to the recorded value of the asset. If impairment is indicated, the
asset value is written down to its fair value. See Notes 4 and 6 regarding
discontinued operations and intangible asset impairment.

                                      F-12


Goodwill

Prior to 2002, the Company amortized goodwill over periods of 15 to 25 years on
the straight-line basis. SFAS 142, which was adopted by the Company on January
1, 2002, provides that goodwill should not be amortized, but shall be tested for
impairment annually, or more frequently if circumstances indicate potential
impairment. The Company recognized no amortization expense in 2002, nor was any
goodwill identified as being impaired based on management's transitional and
annual impairment analyses performed during 2002. Amortization expense related
to goodwill for the years ended December 31, 2001 and 2000 was $6.2 million and
$3.8 million pre-tax, respectively. See Note 8 regarding acquired intangible
assets and goodwill.

Treasury Stock

Treasury stock is accounted for at acquisition cost.

Foreign Currency Translation

Results of operations for foreign entities are translated using the average
exchange rates during the period. Current assets and liabilities are translated
to U.S. dollars using the exchange rates in effect at the balance sheet date,
and the related translation adjustments are reported as a separate component of
stockholders' equity.

New Accounting Pronouncements

In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations," which was adopted by the Company as of January 1, 2003. SFAS No.
143 did not have a material impact on the consolidated financial statements upon
adoption.

In June 2002, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 146 ("SFAS 146"), "Accounting for Costs
Associated with Exit or Disposal Activities." SFAS 146 requires an entity to
recognize, and measure at fair value, a liability for costs associated with an
exit or disposal activity in the period in which the liability is incurred. SFAS
146 supercedes Emerging Issues Task Force Issue ("EITF") No. 94-3, "Liability
Recognition for Certain Employee Termination Benefits and Other Costs to Exit an
Activity (Including Certain Costs Incurred in a Restructuring)." SFAS 146 is
effective for exit or disposal activities that are initiated after December 31,
2002. The Company has adopted the provisions of SFAS 146 effective January 1,
2003. There was no material impact upon adoption.

In November 2002, FASB issued FASB Interpretation No. 45 ("FIN 45"),
"Guarantor's Accounting and Disclosure Requirements for Guarantees, Including
Indirect Guarantees of Indebtedness of Others," which elaborates on the
disclosures to be made by a guarantor in its interim and annual financial
statements about its obligations under certain guarantees that it has issued
along with expanded disclosures of warranty reserves. It also requires that a
guarantor recognize a liability for the fair value of the obligation undertaken
in issuing the guarantee at the inception of the guarantee. This interpretation
incorporates the guidance in FIN 34, "Disclosure of Indirect Guarantees of
Indebtedness of Others," which is being superseded. The initial recognition and
initial measurement provisions of FIN 45 are applicable on a prospective basis
to guarantees issued or modified after December 31, 2002, irrespective of the
guarantor's fiscal year-end and the disclosure requirements are effective for
financial statements of interim or annual periods ending after December 15,
2002. Adoption of FIN 45 did not have a material impact on the consolidated
financial statements. See Note 14 regarding commitments and contingencies.

                                      F-13


In December 2002, FASB issued Statement of Financial Accounting Standards No.
148 ("SFAS 148"), "Accounting for Stock-Based Compensation - Transition and
Disclosure." SFAS 148 amends SFAS 123, "Accounting for Stock-Based Compensation"
and allows two alternative methods of transition for a voluntary change to the
more preferable fair value based method of accounting for stock-based employee
compensation. These methods avoid the ramp-up effect arising from prospective
application of the fair value based method. The Statement also amends APB
Opinion No. 28, "Interim Financial Reporting," and requires disclosure of
comparable information for all companies regardless of whether, when, or how an
entity adopts the fair value based method of accounting and requires the
inclusion of the disclosure in financial reports for interim periods. SFAS 148
is effective for interim and year-end financial statements for fiscal years
ending after December 15, 2002. As previously disclosed, the Company will
continue to account for stock compensation pursuant to APB 25. However, it has
adopted the disclosure provisions of FAS 148.

In January 2003, FASB issued FASB Interpretation No. 46 ("FIN 46"),
"Consolidation of Variable Interest Entities," which addresses the reporting and
consolidation of variable interest entities as they relate to a business
enterprise. This interpretation incorporates and supercedes the guidance set
forth in ARB No. 51, "Consolidated Financial Statements." It requires the
consolidation of variable interests into the financial statements of a business
enterprise if that enterprise holds a controlling financial interest via other
means than the traditional voting majority. The disclosure requirements of FIN
46 are effective immediately for variable interest entities created after
January 31, 2003 and thereafter, or the first reporting period after June 15,
2003 for variable interest entities for which an enterprise holds a variable
interest that it acquired prior to February 1, 2003. The Company does not expect
that the adoption of FIN46 will have a material impact on its future
consolidated financial statements.

3.       BUSINESS ACQUISITIONS:

Effective May 1, 2002, the Company acquired the business and certain assets and
liabilities of Elmore Pipe Jacking, Inc. ("Elmore") for approximately $12.5
million. Elmore was a regional provider of trenchless tunneling, microtunneling,
segmented lining and pipe jacking services in the western U.S. The purchase
price included $8.5 million in cash, settlement of $2.3 million of debt owed by
Elmore to the Company, and the assumption of an additional $1.7 million of
liabilities, of which $0.2 million was interest-bearing and the remainder,
including covenants not to compete, owed to the former owners of the Elmore
assets. The purchase price was allocated to assets acquired and liabilities
assumed based on their respective fair values at the date of acquisition and
resulted in goodwill of $8.9 million. The Company's results reflect the
operating of Elmore's former assets from the date of acquisition. The Elmore
acquisition added $20.7 million of revenues, $1.0 million of operating income,
and $0.6 million of net income in the tunneling segment for the period from May
1, 2002 through December 31, 2002. Pro forma information is immaterial and has
not been presented relative to the Elmore acquisition.

On February 28, 2001, the Company acquired 100% of the stock of Kinsel
Industries, Inc. ("Kinsel") and an affiliated company, Tracks of Texas, Inc.
("Tracks"). Kinsel had operations in pipebursting, microtunneling, wastewater
treatment plant construction, commercial construction and highway construction
and maintenance. Tracks was a real estate and construction equipment leasing
company that primarily leased equipment to Kinsel. The purchase price was
approximately $80 million, paid in a combination of cash, a $5.4 million note to
the seller and 1,847,165 shares of the Company's common stock valued at $35.51
per share. The transaction was accounted for by the purchase method of
accounting, and accordingly, their results are included in the Company's
consolidated income statement from the date of acquisition. The purchase price
was allocated to assets acquired and liabilities assumed based on their
respective fair value at the date of acquisition and resulted in goodwill of
$61.2 million. There are no contingent payments, options, or commitments in
connection with the acquisition. The Company subsequently decided to sell off
portions of Kinsel that did not fit the Company's overall business strategy. In
March 2003, the Company settled various claims against the former shareholders
of Kinsel. See Note 16 for further discussion on the settlement. See Note 4
regarding discontinued operations.

                                      F-14


The following unaudited pro forma summary presents information as if Kinsel and
Tracks had been acquired as of January 1, 2000. The pro forma amounts include
certain adjustments, primarily to recognize depreciation and amortization,
including amortization of goodwill, based on the allocated purchase price of
Kinsel and Tracks assets, and do not reflect any benefits from economies which
might be achieved from combining operations. The unaudited pro forma information
has been presented for comparative purposes and does not necessarily reflect the
actual results that would have occurred nor is it necessarily indicative of
future results of operations of the combined companies (in thousands, except per
share amounts).

During the third quarter of 2000, the Company acquired the remaining 50%
ownership of Insituform Belgium N.V. (formerly known as K-Insituform N.V.), its
joint venture in Belgium, for approximately $0.3 million, along with the
remaining 33% ownership in Insituform France, S.A., for approximately $0.8
million. In addition, in July 2000, the Company completed its acquisition of 50%
of Italcontrolli-Insituform S.r.l. (formerly known as Italcontrolli Nord
S.r.l.), its licensee in Italy, for approximately $1.2 million. There was no
material goodwill resulting from these acquisitions.

In February 2000, the Company acquired the rights to the Insituform CIPP Process
and NuPipe(R) process for the states of New York and New Jersey, through the
purchase of all of the shares of the capital stock in Insituform Metropolitan,
Inc. and the operating assets of certain of its affiliates. The Company paid the
sellers an aggregate of $5.0 million in cash, in addition to assuming operating
liabilities of the acquired business. The acquisition was accounted for by the
purchase method and resulted in goodwill of $4.8 million.

4.       DISCONTINUED OPERATIONS:

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." The Company elected to early adopt the
provisions of SFAS No. 144 for the year ended December 31, 2001. SFAS No. 144
supersedes SFAS No. 121 "Accounting for the Impairment of Long-Lived Assets to
be disposed of" and provides a single accounting model for long-lived assets to
be disposed of by sale. SFAS No. 144 clarifies certain provisions related to
SFAS No. 121 and expands the use of discontinued operations to all components of
a business for which separate results of operations can be identified.

In 2001, the Company made the decision to sell certain operations acquired in
the Kinsel transaction. Accordingly, the Company classified as discontinued the
wastewater treatment plant, commercial

                                      F-15

construction and highway operations acquired as part of the Kinsel acquisition.
These operations are not consistent with the Company's operating strategy of
providing differentiated trenchless rehabilitation and tunneling services. The
Company completed the sale of the wastewater treatment plant effective January
1, 2002. The Company received $1.5 million in cash and a $2.0 million note for a
total sale price of $3.5 million, resulting in a slight loss on the sale. See
Note 16 for a related subsequent event. During the third quarter of 2002, the
Company sold the heavy highway construction business for $2.6 million in cash
and $1.5 million in notes, resulting in a pre-tax gain of $1.5 million, or $0.9
million after-tax, which is reflected in income (loss) from discontinued
operations in the table below. The Company completed the sale of certain assets
and contracts of the Kinsel highway maintenance business during the fourth
quarter of 2002 for certain assumed liabilities, $1.4 million in cash and a $1.5
million subordinated note, with no material gain or loss for the sale. Pursuant
to the terms of the sale agreements described above, the Company retained
responsibility for some uncompleted jobs, which has resulted in the absorption
of additional trailing costs. The Company expects to substantially complete
these jobs in the second quarter of 2003. This completes the disposition of all
material assets classified as discontinued pursuant to the acquisition of
Kinsel. See Note 16 for discussion of the Kinsel escrow settlement subsequent to
December 31, 2002.

For the twelve months ended December 31, 2002, including an after-tax gain of
$0.9 million on the sale of the heavy highway business, discontinued operations
lost $5.9 million on $22.6 million in revenues. As of December 31, 2002 and
December 31, 2001, assets held for disposal totaled $7.9 million and $32.0
million, respectively, and included $0.7 million and $7.6 million of unbilled

5.       RESTRUCTURING:

In the third quarter of 2002, the Company recorded a pre-tax restructuring
charge of $2.5 million ($1.5 million after-tax), $1.3 million of which was
severance costs associated with the elimination of 75 salaried positions,
primarily related to administrative and other overhead functions. An additional
$1.2 million involved related decisions for information technology asset
write-downs, lease cancellations, and disposal of certain identifiable fixed
assets primarily at the corporate level. As of December 31, 2002, the remaining
liability on this restructuring was $1.1 million, of which $0.8 million relates
to future severance costs and $0.4 million relates to retirement of equipment,
both of which are expected to be substantially settled in 2003.

In the fourth quarter of 2001, the Company recorded a pre-tax restructuring
charge of $4.1 million ($2.5 million after tax), $0.9 million of which is
severance costs associated with the elimination of 112 company-wide positions
specifically identified as of December 31, 2001. An additional $3.2 million of
the charge

                                      F-16

relates to asset write-downs, lease cancellations and other costs
associated with the closure of eight facilities in the United States and the
disposal of the associated assets. As of December 31, 2002, the remaining
liability was $0.5 million, $0.3 million of which is for retirement of
equipment, and $0.2 million relates to facilities closure costs, both of which
are expected to be substantially settled in 2003.

6.       INTANGIBLE ASSET IMPAIRMENT:

During the third quarter of 2002, the Company determined that certain patent,
trademark, license and non-compete intellectual property assets had become
impaired due to recent business decisions and other circumstances. No further
bidding or work was performed during 2002 that related to any of the intangible
assets determined to be impaired. The impairment analysis was conducted in
accordance with SFAS 144, which the Company early adopted in 2001, and included
an assessment of future undiscounted cash flows expected to be generated from
the intangible assets. The impact of the impairment charge was $3.5 million
($2.2 million after tax).

8.       ACQUIRED INTANGIBLE ASSETS AND GOODWILL:

In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 142 ("SFAS 142"), "Goodwill and Other
Intangible Assets," which requires that an intangible asset that is acquired
shall be initially recognized and measured based on its fair value. This
statement also provides that certain intangible assets deemed to have an
indefinite useful life, such as goodwill, should not be amortized, but shall be
tested for impairment annually, or more frequently if circumstances indicate
potential impairment, through a comparison of fair value to its carrying amount.
SFAS 142 is effective for fiscal periods beginning after December 15, 2001. The
Company adopted SFAS 142 on January 1, 2002, at which time amortization of
goodwill ceased and a transitional impairment test was performed. The annual
impairment test for goodwill was performed in the fourth quarter of 2002.
Management retained an independent party to perform a valuation of the Company's
reporting units as of these dates and determined that no impairment of goodwill
existed.

Changes in the carrying amount of goodwill for the year ended December 31, 2002
were as follows (in thousands):

The 7.88% Senior Notes may be prepaid at the Company's option, in whole or in
part, at any time, together with a make-whole premium, and upon specified change
in control events each holder has the right to require the Company to purchase
its Senior Notes without any premium thereon. The agreements obligate the
Company to comply with certain financial ratios and restrictive covenants that,
among other things, place limitations on operations and sales of assets by the
Company or its subsidiaries, and limit the ability of the Company to incur
secured indebtedness and liens. Such agreements also obligate the Company's
subsidiaries to provide guarantees to the holders of the Senior Notes if
guarantees are given by them to certain other lenders. The Company was in
compliance with all debt covenants at December 31, 2002.

During 2000, the Company obtained a line of credit facility with the capacity to
borrow up to $50 million. The commitment fee paid per annum by the Company is
0.2% on the unborrowed balance. The Company is obligated to comply with certain
financial ratios, and restrictive covenants, which mirror the Senior Note
agreements. This line of credit facility expires March 31, 2003. The interest
rates under this facility vary and are based on the prime rate. As of December
31, 2002, the rate was 2.19%. The unused availability on the line of credit
facility as of December 31, 2002 was $18.8 million. See Note 16 regarding
subsequent event for refinancing of the credit facility.

At December 31, 2002 and 2001, the estimated fair value of the Company's
long-term debt was approximately $118.2 million and $124.4 million,
respectively. Fair value was estimated using discounted market rates for debt of
similar risk and maturity.

10.      STOCKHOLDERS' EQUITY:

Stock Option Plans

The 2001 Employee Equity Incentive Plan (the "Employee Incentive Plan") provides
for the granting to employees of stock-based awards, including (a) stock
appreciation rights, (b) restricted shares of common stock, (c) performance
awards, (d) stock options and (e) stock units. The maximum number of shares of
common stock which currently may be issued under the Employee Incentive Plan is
1,000,000. The Employee Incentive Plan is administered by the Compensation
Committee of the Board of Directors, which determines the eligibility, timing,
pricing, amount, vesting and other terms and conditions of awards, including
stock option awards. The Company accounts for options granted under this plan in
accordance with APB 25. The exercise price of each option issued under the 2001
Employee Incentive Plan equals the closing market price of the Company's stock
on the date of grant and, therefore, the Company makes no charge to earnings
with respect to these options. Stock options, issued under the 2001 Employee
Incentive Plan, generally vest over three years (with 25% vesting upon grant)
and have an expiration date of up to five to ten years after the date of grant.

The 2001 Non-Employee Director Equity Incentive Plan (the "Non-Employee Director
Incentive Plan") provides for the granting of stock options to non-employee
directors. The total number of shares of common stock available for issuance
under the Non-Employee Director Incentive Plan is 200,000. The Non-Employee
Director Incentive Plan is administered by the Board of Directors. Under the
terms of the Non-Employee Director Incentive Plan, each non-employee director
receives a stock option to purchase shares of common stock each year on the date
of the Annual Meeting of Stockholders (or promptly thereafter, as determined by
the Board), provided that such director continues to be a non-employee director
following such Annual Meeting. The purchase price per share of common stock for
which each option is exercisable is the fair market value per share of common
stock on the date the option is granted.

Each option granted under the Non-Employee Director Incentive Plan is fully
vested and exercisable immediately, and expires not later than ten years from
the date of the grant.

Under the 1992 Employee Stock Option Plan (the "Employee Plan") and Director
Stock Option Plan (the "Director Plan"), the Company was authorized to grant
options to its employees and directors not to exceed 2,850,000 and 1,500,000
shares of common stock, respectively. No options are to be granted under the
Employee Plan or the Director Plan since the adoption of the Employee Incentive
Plan and the Non-Employee Director Incentive Plan. The plans were administered
by the Board of Directors, which determined the timing of awards, individuals
granted awards, the number of options awarded and the price, vesting schedule
and other conditions of the options. The exercise price of each option equaled
the closing market price of the Company's stock on the date of grant and,
therefore, the Company made no charge to earnings with respect to these options.
Options generally vest over three years (with 25% vesting upon grant) and have
an expiration date of up to five to ten years after the date of grant.

In accordance with SFAS No. 123, the Company has estimated the fair value of
each option grant using the Black-Scholes option-pricing model and has included
in Note 2 a table illustrating the effect on net income and earnings per share
had the Company applied the fair value recognition provisions. The following
weighted average assumptions were used for the grants in 2002, 2001, and 2000,
respectively: expected

                                      F-22


volatility of 64%, 75%, and 62%; risk-free interest rates of 3.8%, 4.8%, and
5.1%; expected lives of six, seven and five years and no dividends.

The following tables summarize information about options outstanding at December
31, 2002:

At December 31, 2002, 2,667,994 shares of common stock were reserved pursuant to
stock option plans.

For SFAS 123 disclosure purposes (as presented in Note 2), the weighted average
fair value of stock options is required to be based on a theoretical
option-pricing model such as the Black-Scholes method. In actuality, because the
Company's employee stock options are not traded on an exchange and are subject
to vesting periods, the disclosed fair value represents only an approximation of
option value based solely on historical performance. Employees can receive no
value nor derive any benefit from holding stock options under these plans
without an increase in the market price of the Company's stock over time. Such
an increase in stock price benefits all stockholders commensurately.

Shareholders' Rights Plan

In February 2002, the Company's Board of Directors adopted a Shareholder Rights
Plan. Pursuant to the Shareholder Rights Plan, the Board of Directors declared a
dividend distribution of one preferred stock purchase right ("Right") for each
outstanding share of the Company's common stock, $.01 par value ("Common
Stock"), payable to the Company's stockholders of record as of March 13, 2002.
Each Right, when exercisable, entitles the holder to purchase from the Company
one one-hundredth of a share of a new series of voting preferred stock,
designated as Series A Junior Participating Preferred Stock, $0.10 par value, at
an exercise price of $116.00 per one one-hundredth of a share.

                                      F-23



The Rights will trade in tandem with the Common Stock until ten days after a
"distribution event" (i.e., the announcement of an intention to acquire or the
actual acquisition of 20% or more of the outstanding shares of Common Stock), at
which time the Rights would become exercisable. Upon exercise, the holders of
the Rights (other than the person who triggered the distribution event) will be
able to purchase for the exercise price shares of Common Stock having the then
market value of two times the aggregate exercise price of the rights. The rights
expire on March 12, 2012, unless redeemed, exchanged or otherwise terminated at
an earlier date.

14.      COMMITMENTS AND CONTINGENCIES:

Leases

                                      F-25



The Company leases a number of its administrative operations facilities under
noncancellable operating leases expiring at various dates through 2020. In
addition, the Company leases certain construction, automotive and computer
equipment on a multiyear, monthly or daily basis. During the fourth quarter of
2002, the Company entered into an arrangement for the sale-leaseback of a tunnel
boring machine ("TBM"). Future rent expense on the TBM operating lease will be
$1.7 million annually, extending for 7 years and is included in the minimum
lease payments presented below. No material gain or loss resulted from the
sale-leaseback transaction in 2002. Rent expense under all operating leases for
2002, 2001 and 2000 was $18.6 million, $22.3 million and $17.7 million,
respectively. Rental expense paid to related parties was $600,000, $453,500 and
$392,750 for the years ended December 31, 2002, 2001 and 2000, respectively. At
December 31, 2002, the Company had under lease equipment with an original market
value of approximately $53.0 million.

At December 31, 2002, the future minimum lease payments required under the
noncancellable operating leases were as follows (in thousands):




   Year                Minimum Lease Payments
- ----------            ------------------------

  2005                          6,062
  2006                          4,470
  2007                          3,952

                              -------
  Total                       $44,472
                              =======


Litigation

The Company is involved in certain litigation incidental to the conduct of its
business. In the Company's opinion, none of these proceedings will have a
material adverse effect on the Company's financial position, results of
operations and liquidity. During the third quarter of 2002, a Company crew had
an accident on a cured-in-place pipe project in Des Moines, Iowa. Two workers
died and five workers were injured in the accident. In January 2003, the Company
received notice of multiple claims, totaling more than $3.5 million, from the
buyer of the former Kinsel wastewater treatment division. The claims arise out
of the February 2002 sale of the Kinsel wastewater treatment division and allege
the valuation of the assets sold was overstated. No litigation has been
commenced. The financial statements include the estimated amounts of liabilities
that are likely to be incurred from these and various other pending litigation
and claims.

Retirement Plans

Substantially all of the Company's employees are eligible to participate in the
Company sponsored defined contribution savings plan, which is a qualified plan
under the requirements of Section 401(k) of the Internal Revenue Code. Total
contributions to the domestic plan were $1.7 million, $1.5 million and $4.4
million for the years ended December 31, 2002, 2001 and 2000, respectively.

In addition, certain foreign subsidiaries maintain various other defined
contribution retirement plans. Company contributions to such plans for the years
ended December 31, 2002, 2001 and 2000 were $224,718, $214,552 and $352,000,
respectively.

                                      F-26



Guarantees

The Company has entered into several contractual joint ventures to develop joint
bids on contracts for its installation businesses, and for tunneling operations.
In these cases, the Company could be required to complete the partner's portion
of the contract if the partner is unable to complete its portion. The Company is
at risk for any amounts for which the Company itself could not complete the work
and for which a third party contractor could not be located to complete the work
for the amount awarded in the contract. The Company has not experienced material
adverse results from such arrangements and foresees no future material adverse
impact on financial position, results of operations or cash flows. As a result,
the Company has not recorded a liability on the balance sheet associated with
this risk.

The Company has many contracts that require the Company to indemnify the other
party against loss from claims of patent or trademark infringement. The Company
also indemnifies its bonding agents against losses from third party claims of
subcontractors. The Company has not experienced material losses under these
provisions and foresees no future material adverse impact on financial position,
results of operations or cash flows.

15.      SEGMENT AND GEOGRAPHIC INFORMATION:

The Company has principally three operating segments: rehabilitation, tunneling
and TiteLiner. The segments were determined based upon the types of products
sold by each segment and each is regularly reviewed and evaluated separately.
The rehabilitation segment provides trenchless methods of rehabilitating sewers,
pipelines and other conduits using a variety of technologies including the
Insituform CIPP Process, pipebursting, microtunneling, and sliplining. The
tunneling segment engages in tunneling used in the installation of new
underground services, large diameter microtunneling and sliplining, and the
TiteLiner segment provides a method of lining steel lines with a corrosion and
abrasion resistant pipe. These operating segments represent strategic business
units that offer distinct products and services and serve different markets.

The following disaggregated financial results have been prepared using a
management approach, which is consistent with the basis and manner with which
management internally disaggregates financial information for the purpose of
assisting in making internal operating decisions. The Company evaluates
performance based on standalone operating income.

There were no customers which accounted for more than 10% of the Company's
revenues during each of the three years ended December 31, 2002.

Financial information by segment was as follows at December 31 (in thousands):

16.      SUBSEQUENT EVENTS:

Kinsel Settlement

The Company made various claims against the former shareholders of Kinsel,
arising out of the February 2001 acquisition of Kinsel and Tracks. Those claims
were settled in March 2003 without litigation. Under the terms of the
settlement, 18,891 shares of Company common stock and all of the promissory
notes, totaling $5,350,000 in principal (together with all accrued and unpaid
interest), issued to former Kinsel shareholders in connection with the
acquisition, are to be returned to the Company from the claim collateral escrow
account established at the time of the acquisition. The remaining 56,672 shares
of Company common stock held in the escrow account are to be distributed to the
former Kinsel shareholders. The settlement of the escrow account primarily
relates to matters associated with Kinsel operations which have been sold and
are presented as discontinued operations.

As a result of this settlement, the Company expects to record income, net of
taxes, of approximately $1.9 million in the first quarter of 2003, the
substantial portion of which will be reflected in discontinued operations.

EIG Claim

In January 2003, the Company received notice of multiple claims, totaling more
than $3.5 million, from the buyer of the former Kinsel wastewater treatment
division. The claims arise out of the February 2002 sale of the Kinsel
wastewater treatment division and allege the valuation of the assets sold was
overstated. No litigation has been commenced.

Credit Facility

Effective March 27, 2003, the Company entered into a new three-year bank
revolving credit facility to replace its expiring bank credit facility. This new
facility provides the Company with borrowing capacity of up to $75 million. The
quarterly commitment fee ranges from 0.2% to 0.3% per annum on the unborrowed
balance depending on the leverage ratio determined as of the last day of the
Company's preceding fiscal quarter. At the Company's option, the interest rates
will be either (i) the LIBOR plus an additional percentage that varies from
0.75% to 1.5% depending on the leverage ratio or (ii) the higher of (a) the
prime rate or (b) the federal funds rate plus 0.50%. As of March 27, 2003, the
interest rate on the credit facility was 4.25% and the balance was $40.0
million.

Senior Notes

The Company expects to place additional unsecured senior notes in the maximum
principal amount of $65 million with certain institutional investors through a
private offering made by the Company during the second quarter of 2003.
