In December 1992, in connection with the Company's acquisition (the "IGL
Acquisition") of Insituform Group Limited ("IGL"), the Company's certificate of
incorporation was amended: (x) to divide the Board of Directors of the Company
into three classes, as equal in size as possible, having staggered three-year
terms, with the term of one class expiring each year; (y) to fix the number of
directors of the Company at not less than six nor more than 15, the exact number
to be specified in the By-laws of the Company; and (z) to provide for the
appointment of directors and the filling of vacancies as contemplated by the
agreement dated July 3, 1992, as amended September 1, 1992 (the "IGL Acquisition
Agreement"), among the Company, INA Acquisition Corp. (the Company's
wholly-owned subsidiary), and IGL. Upon consummation of the IGL Acquisition, the
Board of Directors of the Company was reconstituted to include: Messrs.
Spengler, Gorham and Weinig, for a term initially expiring

5
6

at the 1993 annual meeting of stockholders of the Company ("Class I Directors");
Messrs. Chick, Biddelman and Roth, for a term initially expiring at the 1994
annual meeting of stockholders of the Company ("Class II Directors"); and
Messrs, Chandler, Krugman and Wight, for a term initially expiring at the
1995 annual meeting of stockholders of the Company ("Class III Directors").
Messrs. Spengler, Chick, Biddelman, Chandler and Krugman were designated by the
Company, and Messrs. Gorham, Weinig, Roth and Wight were designated by IGL. The
Company has further agreed that during the period from the consummation of the
IGL Acquisition to the sixth anniversary thereof (the "Term"), the Company will
nominate and recommend for re-election to its Board of Directors, upon
expiration of their terms, the Class I Directors, the Class II Directors and the
Class III Directors; and that, if during the Term any director resigns or is
unable to serve for any reason, such vacancy will be filled with a designee
chosen by the remaining members of that director's group and thereafter the
Company will nominate and recommend such designee for election to the Board of
Directors of the Company.

In March 1994, in connection with the commencement of Mr. Richard's
employment as President and Chief Executive Officer of the Company, the Board of
Directors completed action to amend the By-laws of the Company to increase the
size of the Board from nine to ten, and to appoint Mr. Richard as a Class III
Director, to fill the vacancy created by the increase in the size of the Board.

For information concerning the executive officers of the Company, see pages
24 and 25 of the Company's Annual Report on Form 10-K for the year ended
December 31, 1994 as originally filed, under the caption "Item 1.
Business-Executive Officers", which information is incorporated herein by
reference.

No family relationship exists between any of the directors or executive
officers of the Company.

Based solely upon a review of copies of reports received by it pursuant to
Section 16(a) of the Securities Exchange Act of 1934, and the written
representations of its incumbent directors and officers, and holders of more
than ten percent of any registered class of the Company's equity securities, the
Company believes that during 1994 all filing requirements applicable to its
directors, officers and ten percent holders under said section were satisfied,
except that Interstate Properties, a New Jersey general partnership
("Interstate"), and each of its three general partners, Steven Roth, Russell B.
Wight, Jr. and David Mandelbaum, filed a report on Form 4 subsequent to the due
date thereof, disclosing one transaction consisting of the open market purchase
by Interstate of 4,000 shares of class A common, $.01 par value (the "Common
Stock"), of the Company.

ITEM 11. EXECUTIVE COMPENSATION
----------------------
DIRECTOR COMPENSATION

Each director of the Company who is not an operating officer of the Company
is entitled to receive compensation in the amount of $12,000 per annum and
$1,000 per meeting of the Board of Directors attended by such director, plus
reimbursement of his expenses.

James D. Krugman, Chairman of the Board of the Company, holds an option
granted under the Company's 1992 Director Stock Option Plan (the "Director
Plan") on December 13, 1993 covering 95,000 shares of Common Stock, exercisable
at a per share price of $14.50, the closing price of the Common Stock on the
NASDAQ National Stock Market on such date. As a consequence of the exchange of
options previously granted by IGL for options granted by the Company (see
"Stock Plans" below), on December 9, 1992 William Gorham, Sheldon Weinig and
Russell B. Wight, Jr., who became directors of the Company upon consummation of
the IGL Acquisition, were granted options covering 57,720 shares, 22,200 shares
and 16,650 shares of Common Stock, respectively, at exercise prices ranging
from $6.53 to $13.74 per share, calculated in accordance with the provisions of
the IGL Acquisition Agreement. In January 1995, Mr. Weinig exercised options
covering 5,550 shares at an exercise price of $6.53 per share. In July 1993,
options covering 23,310 shares of Common Stock were granted by the Company to
William Gorham in replacement of options then expiring covering the same number
of shares, at the exercise price per share under the prior options of $9.68.

Except as aforesaid, no current director of the Company holds any options
granted by the Company under any stock option plan. Mr. Richard holds additional
options granted in connection with his acceptance of employment with the
Company. For information with respect to such options and other agreements
entered into by the Company and certain directors, see "Certain Agreements with
Directors and Executive Officers" below.

STOCK PLANS

Under the Company's 1983 Stock Option Plan (the "Prior Plan"), there were
outstanding options for 38,728 shares of Common Stock as

9
10

of April 1, 1995. No further options may be granted under the Prior Plan.

In June 1992, the stockholders of the Company approved the Company's 1992
Employee Stock Option Plan (the "Employee Plan"), under which options to
purchase an aggregate of 500,000 shares of Common Stock (as subsequently
increased) were subject to grants to key employees who are not directors
(including executive officers), and the Director Plan, under which options to
purchase an aggregate of 500,000 shares of Common Stock may be granted to
directors of the Company (including executive officers), as previously adopted
by the Board of Directors. In June 1994, the stockholders of the Company
approved an increase in the number of authorized shares of Common Stock
available for issuance under the Employee Plan to 1,000,000 shares.

The Employee Plan is administered by the Compensation Committee of the
Board of Directors, and the Director Plan is administered by the Director Stock
Option Committee of the Board of Directors. Each such committee, with respect to
the plan that it administers, is empowered to determine the persons who are to
receive options, the number of shares to be subject to each option and whether
such options will be incentive stock options or non-qualified stock options.
Pursuant to amendments to the Employee Plan adopted in April 1994, the
Compensation Committee may authorize another committee of the Board of Directors
constituted for such purpose to allocate options approved in the aggregate by
the Compensation Committee among employees who are not officers. The exercise
price of an option under either the Employee Plan or the Director Plan may not
be less than the lesser of the fair market value of the Common Stock on the date
of grant of the option, or the tangible book value per share of Common Stock as
of the end of the fiscal quarter of the Company immediately preceding the grant,
provided that no incentive stock option may be granted at an option price which
is less than the market value per share of the Common Stock on the date of
grant.

In December 1992, the stockholders of the Company approved the INA
Acquisition Corp. Share Option Plan previously adopted by the Board of Directors
and sole stockholder of INA Acquisition Corp. In connection with the
consummation of the IGL Acquisition, options (the "Substitute IGL Options")
covering an aggregate of 562,938 shares of Common Stock (353,612 shares of which
were covered by options outstanding at April 1, 1995), granted pursuant to such
plan in substitution for options (the "IGL Options") outstanding prior to the
IGL Acquisition to acquire Ordinary Shares of IGL, became exercisable. Each
Substitute IGL Option covers the number of shares of Common Stock that would
have been received in the IGL Acquisition had the underlying IGL Option been
exercised for Ordinary Shares in accordance with the terms of such option
immediately prior to the IGL Acquisition (subsequent to vesting thereof
pursuant to the IGL Acquisition Agreement), at a price per share equal to: (x)
the exercise price per share in effect on such

10
11

date times the number of Ordinary Shares previously covered by such IGL Option,
divided by (y) the number of shares of Common Stock covered by such Substitute
IGL Option. The Company caused the adoption of such plan solely in order to
implement the provisions of the IGL Acquisition Agreement, and INA Acquisition
Corp. will not grant any additional options under such plan.

See "Certain Agreements with Directors and Executive Officers" below for a
description of additional options granted to Mr. Richard in connection with his
acceptance of employment with the Company.

CERTAIN AGREEMENTS WITH DIRECTORS AND EXECUTIVE OFFICERS

The Company and James D. Krugman, Chairman of the Board of the Company are
parties to an employment agreement which became effective on December 9, 1992
upon the closing of the IGL Acquisition. Such agreement provides that Mr.
Krugman will serve as Chairman of the Board of the Company until the later of
(i) the sixth anniversary of such closing or (ii) the date of the sixth annual
meeting of stockholders of the Company following July 3, 1992 or until such
other date as Mr. Krugman's employment terminates pursuant to such agreement, at
an annual salary of $100,000. In the event of Mr. Krugman's death, the agreement
terminates automatically. Mr. Krugman may cancel the agreement at any time upon
60 days' written notice delivered to the Company, and the Company may terminate
the agreement upon the failure of Mr. Krugman to perform his duties thereunder
owing to illness or other incapacity, if such failure continues for a period of
more than six months, or if Mr. Krugman commits any act in bad faith and to the
material detriment of the Company or is convicted of a felony.

The Company's arrangements with Jean-Paul Richard, under which Mr. Richard
became President and Chief Executive Officer in November 1993, in addition to
base salary provide for bonus payments in an amount per annum up to 75% of base
salary, conditioned on fulfilling performance criteria. As an inducement to his
accepting employment with the Company, the Board of Directors authorized the
grant to Mr. Richard of a five-year option covering 300,000 shares of Common
Stock, which the Company will register under the Securities Act of 1933,
issuable upon exercise of such option at a per share price of $16.25 (equal to
the closing price of the Common Stock as quoted on the NASDAQ National Stock
Market on the date of grant). Such option vested and became exercisable through
the option term with respect to 50,000 shares upon commencement of employment
and will vest and become exercisable through the option term with respect to the
remainder of such shares on the third anniversary thereof, except that in the
event of: (i) the termination of Mr. Richard's employment without cause, the
option will vest with respect to a share of the portion not then vested
calculated pro-rated on the basis of the proportion that the period of service
bears to three years, and (ii) the election of a Board of Directors other than
pursuant to the IGL

11
12

Acquisition Agreement while Mr. Richard remains employed, the option will become
fully-vested.

The Company also agreed to reimburse Mr. Richard for specified reasonable
relocation costs, and to provide a $700 per month car allowance, reimbursement
for country club membership fees and health insurance benefits. The Company's
arrangements with Mr. Richard provide that in the event Mr. Richard's employment
with the Company is terminated other than for cause, the Company will be
obligated to pay severance to Mr. Richard in an amount equal to two years' base
salary.

In connection with the commencement of his employment as chief financial
officer of the Company, the Company extended a severance arrangement to William
A. Martin pursuant to which, in the event of termination of employment by the
Company without cause, the Company will deliver six months' prior notice thereof
plus payments equal in amount to six months' base salary.

The Company's arrangements with R. William Pittman, under which Mr. Pittman
became Senior Vice President-Operations in October 1993, in addition to base
salary provide for bonus payments in an amount up to $100,000 per annum, based
upon performance criteria. The Company's arrangements with Mr. Pittman provided
for the Company to reimburse Mr. Pittman for reasonable relocation costs, and to
provide a $750 per month car allowance, reimbursement for one country club
membership and medical and life insurance benefits. In the event Mr. Pittman's
employment is terminated by the Company other than for cause, the Company would
be obligated to pay to him amounts equal to twelve months' base salary.

The Company's arrangements with Anthony W. Hooper, under which Mr. Hooper
became Senior Vice President-Marketing in November 1993, in addition to base
salary provide for bonus payments in an amount up to $110,000 per annum based on
performance criteria. The Company's arrangements with Mr. Hooper provided for
the Company to reimburse Mr. Hooper for reasonable relocation costs, and to
provide a $700 per month car allowance, reimbursement for one country club
membership and medical and life insurance benefits. In connection with his
relocation to Memphis, the Company extended an interest-free bridge loan in the
amount of $230,000 to Mr. Hooper, which was repaid in August 1994. In the event
Mr. Hooper's employment is terminated by the Company other than for cause, the
Company would be obligated to pay to him amounts equal to twelve months' base
salary.

The Company's arrangements with Raymond P. Toth, under which Mr. Toth
became Vice President-Human Resources in February 1994, in addition to base
salary provide for bonus payments in an amount up to 40% of base salary per
annum, based upon performance criteria. The Company's arrangements with Mr. Toth
also provided for the Company to reimburse Mr. Toth for reasonable relocation
costs, and to provide medical and life insurance benefits. In connection with

12
13

his relocation to Memphis, the Company extended an interest-free bridge loan in
the amount of $110,000 to Mr. Toth, which was repaid in October 1994.

The Company had consulting arrangements with Brian Chandler and Douglas K.
Chick through December 1994, pursuant to which the Company remunerated each in
the amount of $5,000 per month, in exchange for consultation in connection with
development of the European market for the NuPipe(registered trademark) Process,
the Company's second trenchless pipeline rehabilitation process. Each of Messrs.
Chandler and Chick is a director of the Company and a member of a group (the
"Ringwood Group"), within the meaning of Section 13(d) of the Securities
Exchange Act of 1934, which holds in excess of 5% of the outstanding Common
Stock. The Company's arrangements with Messrs. Chandler and Chick, respectively,
were terminable at will by either the Company or the consultant, and provided
for devotion by Messrs. Chandler and Chick, respectively, of such business time
as would be required by the Company and reimbursement by the Company of
out-of-pocket expenses incurred in connection with provision of such consulting
services. Such arrangements were terminated by the Company in December 1994.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
----------------------------------------------

In connection with the IGL Acquisition, and so as to enable the IGL
Acquisition to qualify as a pooling-of-interests under United States generally
accepted accounting principles, the Company, Parkwood, Ringwood, and Brian
Chandler and Douglas K. Chick entered into an agreement dated July 3, 1992
pursuant to which a prior pledge agreement extended by Messrs. Chandler and
Chick and Parkwood, covering Ordinary Shares, of IGL and securing a promissory
note from Mr. Chandler and Parkwood to the Company were, together with Mr.
Chick's guaranty of such note, cancelled, and in exchange Messrs. Chick and
Chandler and Ringwood executed and delivered to the Company a substitute stock
pledge agreement (the "New Pledge Agreement"), and Ringwood executed and
delivered to the Company a secured non-recourse promissory note in the initial
principal amount of $3,623,842.40 (the "Non-Recourse Note"). Parkwood and
Messrs. Chandler and Chick, together with Ringwood and Barford, are members of
the Ringwood Group, and Messrs. Chandler and Chick are directors of the
Company. The Non-Recourse Note bears interest at a rate per annum equal to
2-1/2% above the prime rate from time to time in effect at Citibank, N.A. and
is due July 3, 1995. Pursuant to the New Pledge Agreement, and as security for
the Non-Recourse Note, Ringwood and Messrs. Chick and Chandler pledged to the
Company 255,801 shares of class B common stock $.01 par value, of the Company
beneficially owned by them (which, in connection with the IGL Acquisition and
in accordance with their terms, were converted into shares of Common Stock on a
share-for-share basis). During the year ended December 31, 1994, Ringwood paid
to the Company $352,892 in interest on the Non-Recourse Note.

As principal stockholders of IGL, the members of the Ringwood Group and
Interstate Properties (each, a "Registration Rights Stockholder"), in connection
with the IGL Acquisition, received certain registration rights covering the
shares of Common Stock issued in exchange for their Ordinary Shares, and all
other shares of Common Stock held by them. Such agreement terminates in May
1999. Under such agreement, a Registration Rights Stockholder may demand
registration under the Securities Act of 1933 on one occasion (unless the
Company is entitled to use a registration statement on Form S-3, in which case
each Registration Rights Stockholder is entitled to three demand registrations)
of no less than 500,000 shares of Common Stock. In addition, the Registration
Rights Stockholders are entitled to incidental registration rights, during the
term of such agreement, with respect to the shares of Common Stock beneficially
owned by them.

In order to finance a portion of the purchase price for its acquisition of
Insituform Midwest, Inc., in July 1993 the Company sold its 8.5% senior
subordinated note in the principal amount of $5,000,000 (the "Subordinated
Note"), and related warrants exercisable with respect to 350,877 unregistered
shares of Common

18

Stock, to Hanseatic Corporation. Paul Biddelman, a director of the Company, is
Treasurer of Hanseatic. The Subordinated Note requires quarterly payments of
interest at 8.5% per annum and installments of principal in the amount of
$1,000,000 on each of the fifth through eighth anniversary dates of closing,
with the entire remaining principal due nine years after closing. The
Subordinated Note is subordinated to bank and other institutional financing, and
purchase money debt incurred in connection with acquisitions of businesses, is
prepayable at the option of the Company after the second anniversary of closing,
at premiums until the fifth anniversary of closing ranging from 3% to 1% of the
amount prepaid, and is subject to defeasance at any time while prepayment is not
permitted in the event the Company deposits cash or government securities
sufficient to service payments under the note. During the year ended December
31, 1994, the Company paid to Hanseatic $425,000 in interest on the Subordinated
Note. The warrants are exercisable, at the election of the holder, through July
26, 1998, at a price per share of Common Stock of $14.25, and such shares are
entitled to demand and incidental registration rights.

James D. Krugman, Chairman of the Board of the Company and Howard Kailes,
Secretary of the Company, are members of the law firm of Krugman, Chapnick &
Grimshaw. During the year ended December 31, 1994, Krugman, Chapnick & Grimshaw
received fees for legal services rendered to the Company of $755,000, together
with reimbursement of out-of-pocket expenses of $161,745. It is expected that
Krugman, Chapnick & Grimshaw will continue to render legal services to the
Company in the future.
