PART I

Item 1. Business

GENERAL

Insituform Technologies, Inc. (the "Company") 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
Process") contributed approximately 74% of the Company's revenues during the
Company's most recent fiscal year.

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 revenues of approximately $50
million from water and sewer work. In addition to trenchless pipe rehabilitation
services, it performs some open-cut pipe construction and erects water and sewer
treatment plants. Kinsel generated an additional $50 million in 2000 from
highway, bridge, airport and commercial construction. While valuable and
profitable, these operations do not fit the Company's strategy. The Company
expects to search for a possible buyer for these operations.

The Company was incorporated in Delaware in 1980 under the name
Insituform of North America, Inc., in order to act as the exclusive licensee of
the Insituform Process in most of the United States, and to license other
companies to market and provide Insituform installation services in return for
royalties and sales from materials manufactured by the Company.
Contemporaneously with the consummation in 1992 of the Company's acquisition of
its licensor, the name of the Company was changed to Insituform Technologies,
Inc. As a result of its successive licensee acquisitions, the Company has
further integrated its business to perform the entire process of manufacture and
installation using its trenchless processes.

As used in this Annual Report on Form 10-K, the term the "Company"
refers to the Company and, unless the context otherwise requires, its direct and
indirect subsidiaries. For certain information concerning each of the Company's
industry segments and domestic and foreign operations, see Note 14 of the Notes
to the Company's Consolidated Financial Statements included in response to "Item
14. Exhibits, Financial Statement Schedules, and Reports on Form 8-K," which
information is incorporated herein by reference.

This Annual Report on Form 10-K contains various forward looking
statements and information that are based on information currently available to
management and management's beliefs and assumptions. When used in this document,
the words "anticipate," "estimate," "believes," "plans," and similar expressions
are intended to identify forward-looking statements, but are not the exclusive
means of identifying such statements. Such statements are subject to risks and
uncertainties, and the Company's actual results may vary materially from those
anticipated, estimated or projected due to a number of factors, including,
without limitation, the competitive environment for the Company's products and



1

services, the geographical distribution and mix of the Company's work, and other
factors set forth in reports and other documents filed by the Company with the
Securities and Exchange Commission from time to time.

TECHNOLOGIES

Pipeline System Rehabilitation.

The Insituform 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.

The NuPipe(R) process (the "NuPipe Process") entails the
manufacture of a folded replacement pipe from a thermoplastic material
which is stored on a reel in a reduced shape. The pipe is heated at the
installation site in order to make it flexible enough to be inserted
into an existing conduit, pulled into place and then sequentially
expanded to match the existing conduit by internal heat and pressure
and progressive rounding, creating a tight fit against the conduit
being repaired.

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

Microtunneling is a remotely controlled, guided, pipe-jacking
process that provides continuous support to the excavation face and
does not require personnel entry into the tunnel. Applications are
typically 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 basically entails pushing or pulling 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. Typically the annular
space between the new pipe and host pipe is filled with a grout
material.

See "Patents and Licenses" below for information concerning
the Company's Thermopipe(R) process (the "Thermopipe Process"), which
was not material to the Company's results of operations during the year
ended December 31, 2000.

Corrosion and Abrasion Protection. 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.

Tunneling. Tunneling typically encompasses the construction of
man-entry sized pipelines with access only through vertical shafts. Although
tunnels can be hand-dug, typically a steerable, locally-controlled tunnel boring
machine (TBM) is utilized. For pipe installation, the TBM leads a string of
jacked pipes.

REHABILITATION ACTIVITIES

The Company conducts its rehabilitation activities principally through
direct installation and other construction operations performed directly and
through wholly-owned and, in some cases, majority-owned, subsidiaries. In
addition, 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, 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 encourage additional royalties,
sales of its products and exploitation of its trenchless rehabilitation
processes.

The Company's principal rehabilitation activities in North America are
conducted directly or through subsidiaries which hold the Insituform Process and
NuPipe Process rights for substantially all of 44 of the 50 states, in addition
to Puerto Rico, the U.S. Virgin Islands and Canada, and the rights to the
Thermopipe Process. In February 2000, the Company acquired the operations of
Insituform Metropolitan, Inc. and certain of its affiliates, the Company's
licensees in the states of New York and New Jersey, and has integrated these
territories into its rehabilitation activities. See "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of
Operations-Liquidity and Capital Resources."

Outside of North America, the Company conducts Insituform Process or
NuPipe Process direct installation operations through its subsidiaries in the
United Kingdom, France, Spain, the Netherlands and Belgium. See "Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations-Liquidity and Capital Resources." Through the operations of 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.

North American rehabilitation operations are headquartered in
Chesterfield, Missouri, with principal operations facilities maintained in
approximately 13 locations geographically dispersed through all major regions.
European operations are headquartered in Paris, France, with regional operations
facilities located in the United Kingdom, the Netherlands, Spain and Mitry Mory,
France.

The worldwide rights to the TiteLiner Process are applied by the
Company through its United Pipeline System division, which offers corrosion and
abrasion protection work worldwide.

The Company, through its subsidiary, Affholder, Inc., in addition to
tunneling, offers a range of pipe system rehabilitation services.

The direct installation business of the Company is project-oriented,
and contracts may be obtained through competitive bidding, usually requiring
performance at a fixed price. The profitability of these operations to the
Company depends upon the ability to estimate costs accurately, and such
estimates may prove to be inaccurate as a result of unforeseen conditions or
events. A substantial proportion of the work on any given project may be
subcontracted out to third parties by the Company.

Proper trenchless installation requires certain expertise that is
acquired on the job and through training, and, if an installation is improperly
performed, the Company may be required to repair the defect, which may involve
excavation. The Company, accordingly, has incurred significant costs in
establishing new field installation crews, in training new operations personnel
and in equipping its direct installation staff.

The Company generally invoices installation revenues on a
percentage-of-completion basis. Under ordinary circumstances, collection from
governmental agencies in the United States is made within 60 to


3

6

90 days of billing. In most cases, five to 15 percent of the contract value is
withheld by the owner until testing is completed or the warranty period has
expired.

The Company is required to carry insurance and bonding in connection
with certain direct installation projects and, accordingly, 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 direct 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's principal rehabilitation activities are conducted through
the following majority-owned subsidiaries:



Subsidiary Interest
- ---------- --------

Insituform France S.A. 99.99% of stock(1)
United Pipeline de Mexico, S.A. 55% of stock(2)
Video Injection S.A. 79.8% of stock(3)


- -----------------

(1) The remaining interest is held by the subsidiary's principals.
(2) The remaining interest is held by a subsidiary of Produtos y
Servicios Miller de Mexico, S.A.
(3) The remaining interest is held by the subsidiary's principal
employees and is subject to purchase by the Company in September 2003
(or earlier in specified events).

The Company's rehabilitation activities also extend to the grant of
licenses for the Insituform 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. The
licenses generally grant to the licensee the right to utilize the know-how and
practice the invention of the patent rights (where they exist) relating to the
subject process, and to use the Company's copyrights and trademarks. At present,
the Insituform Process is commercialized under license by an aggregate of 31
unaffiliated licensees and sublicensees, and the NuPipe Process is
commercialized under license by an aggregate of 5 unaffiliated licensees.

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.
Domestic licensees are also obligated to pay specified royalty surcharges on
their sales and contracts outside of their licensed territories, which are then
paid by the Company to the domestic licensee in whose territory the installation
was performed. 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
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 Germany, on an exclusive basis, and in the United
Kingdom, on a non-exclusive basis.

Insituform East, Incorporated ("East") holds six Sub-Licenses to the
Insituform Process to operate in the States of Virginia, Delaware, Maryland,
Ohio, a portion of Kentucky, West Virginia and the District of Columbia under
the Company's exclusive license to the Insituform Process for entire United
States.

(The United States rights to the Insituform 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 Process and technology in the condition and state as commercially
practiced on the date of settlement.

As previously reported by the Company and Insituform Netherlands
initiated litigation against Insituform 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.

Defendants have filed an answer and counterclaim denying the material
allegations of the Company's amended complaint and seek, among other things,
declarations and injunctions essentially the opposite of those requested by the
Company. East has petitioned the Court for leave to amend its answer and
counterclaims to include a defense of patent misuse which East contends
prohibits the Company from enforcing the royalty provisions under its
Sub-Licenses. The Court has not yet acted upon such motion for leave to amend
and the Company has opposed such motion. Even if the Court were to grant East's
motion for leave to amend, the Company believes it has substantial and
meritorious defenses to East's allegations. In any event, should East prevail
under its theories, or if the Company should fail under its theories, the result
would not have a material adverse effect on the Company's financial performance
or income.

OWNERSHIP INTERESTS IN LICENSEES

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 and NuPipe Processes 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 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 50 percent joint venture interest in Ka-Te
Insituform A.G., the Company's licensee of the Insituform Process in
Switzerland, Liechtenstein and Voralberg, Austria. The remaining interest is
held by Ka-Te Holding A.G.

The Company has also entered into several contractual joint ventures in
order to develop joint bids on contracts for its direct installation business,
and for tunneling operations. The Company continues to investigate opportunities
for expanding its business through such arrangements.

MARKETING

The Company has focused the marketing of its rehabilitation
technologies primarily on the municipal wastewater markets worldwide, which the
Company expects to remain the largest part of its


5

8

business for the foreseeable future. The Company 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 intends that its marketing and sales processes will undergo
significant changes during 2001, as the Company builds on its target market
approach to selling. Historically, the Company's sales effort focused on larger
cities, where it built customer relationships at the technical level. To help
shape decision-making at every step, the Company intends to formalize its sales
effort with a multi-level sales force structured around key accounts, focusing
on engineers, consultants, administrators and elected officials, in addition to
technical staff.

The Company's distribution efforts are implemented predominantly
through the direct installation activities. See "Rehabilitation Activities"
above for a description of the Company's licensing operations and "Ownership
Interests in Licensees" for a description of investments in licensees. The
Company's unaffiliated licensees are responsible for marketing and sales
activities in their respective territories, and each has a staff for that
purpose.

The Company offers its corrosion and abrasion protection technologies
worldwide to line new and existing steel pipelines.

No customer accounted for more than ten percent of the Company's
consolidated revenues during the years ended December 31, 2000, 1999 and 1998,
respectively.

BACKLOG

At December 31, 2000 and 1999, respectively, the Company recorded
backlog from construction operations (excluding projects where the Company has
been advised that it is the low bidder, but not formally awarded the contract)
in the amounts of approximately $114.8 million and $132.3 million, respectively.
The Company anticipates that substantially all construction backlog recorded at
December 31, 2000 will be completed in 2001.

PRODUCT DEVELOPMENT

The Company, by utilizing its own laboratories and test facilities and
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, 2000, 1999 and 1998, the Company spent approximately $2.4 million, $2.4
million and $2.2 million, respectively, on all research and development
activities.

MANUFACTURING AND SUPPLIERS

The Company maintains its principal North American liner manufacturing
facility in Batesville, Mississippi, with an additional facility located in
Memphis, Tennessee. In Europe, Insituform Linings Plc ("Linings"), a
majority-owned subsidiary, manufactures and sells linings 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. The Company also maintains a liner manufacturing facility in
Matsubuse, Japan.

Although raw materials used in the Company's Insituform products are
typically available from multiple sources, the Company's historical practice has
been to purchase materials from a limited number


6

9

of suppliers. The Company maintains its own felt manufacturing facility
contiguous to its Insitutube 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 it 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 corporations should there be a
need for alternative resin sourcing. The Company believes that the sources of
supply in connection with its Insituform operations are adequate for its needs.

The Company purchases the thermoplastic pipe to satisfy the substantial
portion of its NuPipe requirements from an unaffiliated party. The Company
believes that alternative sources of supply for its pipe requirements in
connection with the NuPipe Process are available. If the Company were unable to
obtain its NuPipe requirements under its existing third party arrangements, the
Company might be adversely affected until arrangements with alternative sources
are formulated.

Under its arrangements for the acquisition of the Thermopipe Process,
the seller will to continue to manufacture and supply Thermopipe products to the
Company through 2004.

The Company sells liners and related products utilized in the
Insituform Process, and the thermoplastic pipe utilized in the application of
the NuPipe Process, to its licensees, when appropriate pursuant to fixed-term
supply contracts. Under the arrangements assumed in connection with the
acquisition of the Thermopipe Process, the Company also furnishes Thermopipe
products to its approved contractors and licensees.

The Company manufactures certain equipment used in its corrosion and
abrasion protection operations, and, in connection with any licenses to
unaffiliated parties, will sell such equipment to its licensees.

PATENTS AND LICENSES

The Company currently holds 69 patents in the United States relating to
the Insituform Process, the last of which to expire will remain in effect until
2017, and has obtained patent protection in its principal overseas markets
covering aspects of the Insituform Process. These patents cover certain aspects
of the Insituform Process, including the process of reconstructing the pipeline.
The Company's patent relating to the resin saturation process expired in
February 2001. The patent relating to the manufacture of liners will expire in
May 2001. Two of the significant patents relating to the Insituform Process,
covering, respectively, the curing of a resin-impregnated tube and material
aspects of the inversion process, have expired where previously in effect.

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 or that they are sufficient to afford
protection against another company utilizing a process similar to the Insituform
Process. The Company's business could be adversely affected by increased
competition in the event that one or more of the patents were adjudicated to be
invalid or inadequate in scope to protect the Company's operations or upon
expiration of the patents. The Company believes, however, that although the
Company has relied on the strength and validity of its patents, the Company's
long experience with the Insituform Process, its continued commitment to support
and develop the

7


10

Insituform 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.

Twelve patents covering the NuPipe Process or the materials used in
connection with the NuPipe Process have been issued in the United States. The
Company holds patents in connection with the NuPipe Process in 17 other
countries.

The Company believes that the success of its corrosion and abrasion
protection business, operated through its United Pipeline Systems division, will
depend primarily upon its proprietary know-how and its marketing and sales
skills. The Company holds two patents issued in the United States and one patent
outside of the United States relating to the Thermopipe Process for
rehabilitating potable water and other aqueous fluid pipes. See "Item 7.
Management's Discussion and Analysis of Financial Condition and Result of
Operating-Liquidity and Capital Resources."

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. See "Government Regulation" below. 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, 2000, the
Company did not have any material operations under this license. The Company is
renegotiating the terms of this license.

COMPETITION

The pipeline reconstruction, rehabilitation and repair business is
highly competitive, and the Company competes against many companies, some of
which have far greater financial resources and experience than the Company.
Accordingly, there can be no assurance as to the success of the Company's
processes in competition with such companies and alternative technologies for
pipeline rehabilitation.

In each of its rehabilitation markets, the Company currently faces
competition from more conventional methods, including: (i) total replacement,
which is the excavation and replacement of an entire section of pipe; (ii) point
repair, which is the replacement of cracked or structurally failed sections of
pipes by actual excavation and replacement; (iii) sliplining, which is the
insertion of a smaller pipe within an existing deteriorated pipe; and (iv) the
placement of gelatinous material, hydraulic cement, or other acceptable material
in defective pipes to repair leaks and prevent infiltration in gravity sewers.

In addition, the Company faces competition from other trenchless
processes throughout the world. In the United States, the Company faces
competition from several cured-in-place processes and, outside of the United
States, from additional cured-in-place processes currently in regional use. The
Company also faces competition from several fold and formed thermoplastic
processes. Several companies offer in-place polyethylene lining systems which
compete with the Company's abrasion and corrosion protection technologies.

The Company's trenchless processes may also encounter competition from
alternative trenchless approaches such as pipebursting and other methods.
Kinsel, acquired by the Company in February 2001, employs the pipebursting,
microtunneling and sliplining methods.

The Company's tunneling operation competes with utility contracting
firms throughout North America.

SEASONALITY

Although the Company's operations can be affected by severe weather,
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, 2000, the Company employed 1,771 individuals.
Certain of the Company's contracting operations are parties to collective
bargaining agreements covering an aggregate of 213 employees. The Company
generally considers its relations with its employees to be good.

GOVERNMENT REGULATION

The Company and its licensees are required to comply with all
applicable U.S. federal, foreign, state and local statutes, regulations and
ordinances. In addition, the Company's direct installation and other
construction operations, and those of its licensees, may have to comply with
relevant 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 direct installation operations and those of its licensees, are
subject to state and national environmental protection regulations, none of
which presently has 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 direct installation operations have
established monitoring programs relating to the use of solvents, further
restrictions could be imposed on the use of solvents or the thermosetting resins
used in the Insituform Process. The Company believes that it is in material
compliance with environmental 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. Because of the need
for dedicated equipment in connection with use of these products in drinking
water applications, and the time required for the marketing process, the Company
does not expect meaningful revenues from drinking water rehabilitation at least
through 2001.
