Q UESTIONS AND A NSWERS A BOUT T HE M EETING A ND V OTING

Who may vote?

You may vote if you owned shares at the close of business on March 1, 2006, the record date for our 2006 annual meeting of stockholders. You are entitled to one vote for each share you owned on that date for each director to be elected and on each other matter presented at the meeting. As of March 1, 2006, we had 27,058,634 shares of Class A common stock, $.01 par value, outstanding. We have no class or series of voting stock outstanding other than the common stock.

What am I voting on?

 
·
First, you are voting to elect eight directors. Each director, if elected, will serve a term of one year or until his or her successor has been elected and qualified.

Our board of directors recommends a vote “FOR” the election of each of the nominees for director.

 
·
Second, you are voting to approve the 2006 Non-Employee Director Equity Incentive Plan.

Our board of directors recommends a vote “FOR” the approval of the 2006 Non-Employee Director Equity Incentive Plan.

Fourth, you are voting to approve the 2006 Executive Performance Plan.

Our board of directors recommends a vote “FOR” the approval of the 2006 Executive Performance Plan.

 
·
Fifth, you are voting to ratify the appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ending December 31, 2006.

Our board of directors recommends a vote “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ending December 31, 2006.

 
·
In addition, you may vote on other business, if it properly comes before the meeting, or any adjournment(s) of the meeting.

How do I vote?

 
·
By Written Proxy: You can vote by written proxy. If you sign and return the enclosed proxy card, the shares represented by the proxy will be voted in accordance with the terms of the proxy, unless you subsequently revoke your proxy. You can return your proxy card in the enclosed envelope, which requires no postage if mailed in the U.S.

 
·
In Person: If you are a record stockholder, you can vote in person at the meeting.

- 2 -

What is the difference between a record stockholder and a stockholder who holds shares in street name?

 
·
If your shares are registered in your name, you are a record stockholder.

 
·
If your shares are in the name of your broker or bank, your shares are held in street name.

How many votes are needed to approve the proposals?

 
·
Directors are elected by a plurality vote. That means that the eight nominees who receive the most votes are elected. A majority vote is not required.

 
·
Approval of the 2006 Non-Employee Director Equity Incentive Plan requires the affirmative vote of a majority of the shares of our common stock cast on the proposal.

 
·
Approval of the 2006 Employee Equity Incentive Plan requires the affirmative vote of a majority of the shares of our common stock cast on the proposal.

 
·
Approval of the 2006 Executive Performance Plan requires the affirmative vote of a majority of the shares of our common stock cast on the proposal.

 
·
Ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ending December 31, 2006 requires the affirmative vote of a majority of the shares of our common stock cast on the proposal.

Can I revoke my proxy?

Yes. You can revoke your proxy by:

 
·
giving written notice to our corporate Secretary prior to the actual vote at the meeting,

 
·
delivering a later-dated proxy card prior to or at the meeting, or

 
·
voting in person at the meeting.

What is the record date and what does it mean?

The record date for the 2006 annual meeting of stockholders is March 1, 2006. The record date is set by our board of directors, as required by Delaware law. Record stockholders at the close of business on the record date are entitled to:

 
·
receive notice of the meeting, and

 
·
vote at the meeting, and at any adjournment(s) of the meeting.

What if I do not specify my vote when I return my proxy?

You should specify your choice for each proposal on the enclosed proxy card. If no specific instructions are given, proxies that are signed and returned will be voted “FOR” the election of all director nominees, “FOR” the approval of the 2006 Non-Employee Director Equity Incentive Plan, “FOR” the approval of the 2006 Employee Equity Incentive Plan, “FOR” the approval of the 2006

- 3 -


Executive Performance Plan and “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ending December 31, 2006.

How are designations to “withhold authority,” broker non-votes and abstentions counted?

If you designate on the proxy that you are “withholding authority” to vote for a director nominee or nominees, your shares will be counted as present for the purpose of determining the presence of a quorum for transacting business at the meeting, but will not have the effect of a vote against the director nominee or nominees. As discussed above, a plurality of the votes cast is required for the election of directors, which means that the nominees with the eight highest vote totals will be elected as directors. As a result, a designation on the proxy that you are “withholding authority” for a director nominee or nominees will only have the effect of lowering the vote totals of the individual directors for whom authority is withheld.

Broker “non-votes” will not be counted as present for the purpose of determining the presence of a quorum unless these shares are voted on another matter presented at the meeting. A broker “non-vote” occurs when a broker or nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker or nominee:

 
·
has not received voting instructions on a particular matter from the beneficial owner or persons entitled to vote, and

 
·
does not have the discretionary voting power on the matter.

Abstentions will be counted as present for the purpose of determining the presence of a quorum for transacting business at the meeting and as votes cast on Proposals 2 through 5. Because these proposals require a majority of the votes cast for approval, an abstention will have the effect of a vote against the proposal.

What is a quorum?

A majority of the outstanding shares of our common stock must be represented, in person or by proxy, at the meeting to constitute a quorum for purposes of conducting business at the meeting.

P ROPOSAL 1: E LECTION O F D IRECTORS

At the meeting, stockholders will elect eight directors, each to serve a term of one year or until a successor is elected and qualified. Unless otherwise instructed in the proxy, each of the persons named on the accompanying proxy card intends to vote the shares represented thereby in favor of the eight nominees listed under “Certain Information Concerning Director Nominees” below and, in any event, may not vote the shares for a greater number of persons than the eight nominees named.

Each director nominee is presently serving as a director of our company. We have no reason to believe that any of the director nominees will be unable or will decline to serve. If, however, any nominee should become unable or unwilling to serve, the persons named on the accompanying proxy card will vote the shares represented by the proxy for another person duly nominated by our board, based on the recommendation of our Corporate Governance & Nominating Committee, to act in the nominee’s place, or, if no other person is so nominated, to vote the shares only for the remaining nominees. Our board of directors recommends a vote “FOR” each of the nominees for director.

C ORPORATE G OVERNANCE

Independent Directors

Based on the findings of our board’s Corporate Governance & Nominating Committee, our board has determined that the following directors are “independent directors” as defined by the rules applicable to companies listed on The Nasdaq Stock Market:

Stephen P. Cortinovis                                           Alfred T. McNeill
Stephanie A. Cuskley                                            Sheldon Weinig

Non-Executive Chairman of the Board

The Chairman of the Board position is a non-executive position. Alfred L. Woods has served as our non-executive Chairman since July 2003.

Our non-executive Chairman is responsible for the smooth functioning of our board, enhancing its effectiveness. The non-executive Chairman guides the processes of our board, setting the agenda for, and presiding at, board meetings. Our non-executive Chairman also presides at stockholder meetings, and ensures that directors receive appropriate information from our company to fulfill their responsibilities.

Our non-executive Chairman is an ex officio member of each standing board committee, providing guidance and, like all directors, taking an active role in evaluating our Chief Executive Officer.

Our non-executive Chairman acts as a regular liaison between our board and our Chief Executive Officer, consulting regularly with our Chief Executive Officer over business matters and providing our Chief Executive Officer with more immediate consultation and advice on material business decisions which require prompt reflection or policy interpretation.

The non-executive Chairman has no operating or independent oversight authority or responsibility. All oversight authority and responsibility remains with our full board or its designated committees, and all executive authority and responsibility remains with our Chief Executive Officer.

R EPORT OF THE A UDIT C OMMITTEE

The board’s Audit Committee operates under a written charter, which was adopted by our board of directors.

The Audit Committee received and discussed with PricewaterhouseCoopers LLP their written disclosures and letter regarding any significant relationships that could impair PricewaterhouseCoopers LLP’s independence (as required by Independence Standards Board Standard No. 1), and considered the compatibility of non-audit services with PricewaterhouseCoopers LLP’s independence. Based upon the above reviews and discussions, the Audit Committee recommended to the board that our audited consolidated financial statements for 2005 be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2005.

I NDEPENDENT A UDITORS F EES

Consistent with its charter adopted by our board of directors, the Audit Committee pre-approves all auditing services and all significant non-audit services (to the extent such non-audit services are permissible) to be provided by our independent auditors. Proposed auditing and non-audit services are presented to our Audit Committee periodically for pre-approval, based on a budget that includes a description of, and a budgeted amount for, particular categories of audit services, non-audit services, tax services and other services. The Audit Committee’s approval is required to exceed the budgeted amount. In addition, as permitted by law, the Chair of our Audit Committee may pre-approve services or changes to estimated, approved fees. If the Audit Committee Chair pre-approves services on behalf of the Audit Committee, the services are presented to our Audit Committee for ratification at its next regularly scheduled meeting.

Tax Fees. In 2005, we paid PricewaterhouseCoopers LLP $380,844 for tax services, which primarily consisted of services for federal, state and international tax compliance, tax planning and tax consultation, exclusive of tax services rendered in connection with the audit. Our Audit Committee pre-approved all of these services. In 2004, we paid an aggregate of $344,000 to PricewaterhouseCoopers LLP for these services.

C OMPENSATION C OMMITTEE R EPORT ON
E XECUTIVE C OMPENSATION
 
The Compensation Committee of our board of directors consists of three directors: Juanita H. Hinshaw (Chair), John P. Dubinsky and Alfred T. McNeill, each of whom is an independent director.

The Compensation Committee has a formal charter, pursuant to which it is directed to:

 
·
assist our board in the discharge of our board’s responsibilities relating to the compensation of our directors and executives,

 
·
issue a report on executive compensation in accordance with applicable requirements, including the rules and regulations of the Securities and Exchange Commission, for inclusion in our annual proxy statement, and

 
·
administer, and make recommendations with respect to, our incentive compensation plans and equity - based plans.

Specifically, the duties and responsibilities of our Compensation Committee under its charter are to:

 
·
periodically review and approve our corporate goals and objectives relevant to the compensation of our Chief Executive Officer and other executive officers,

 
·
evaluate our Chief Executive Officer’s and other executive officers’ performance in light of our goals and objectives,

 
·
assess our competitive position for the components of executive compensation on a national and local level as well as in our industry and consider different compensation approaches,

 
·
determine the compensation level of our Chief Executive Officer and our other executive officers,

 
·
annually evaluate the performance of our Compensation Committee, and

 
·
recommend to our board specific amounts and forms of director compensation based on general guidelines established by our Corporate Governance & Nominating Committee.

Our Compensation Committee charter requires that the compensation of our Chief Executive Officer be determined by our Compensation Committee meeting in an executive session without our Chief Executive Officer present. The compensation of our other executive officers must be determined by our Compensation Committee meeting in an executive session in which our Chief Executive Officer may be present, by invitation of the committee, but may not vote.

In connection with our Compensation Committee’s review and approval of our Chief Executive Officer’s long-term compensation, the charter requires the Compensation Committee to consider the following factors:

 
·
our performance and relative total shareholder return,

- 13 -



 
·
the value of such awards granted to other chief executive officers at comparable companies, and

 
·
the awards granted to our Chief Executive Officer in prior years.

Our Compensation Committee establishes the overall compensation philosophy for our company, but it may delegate the determination and administration of non-executive officer compensation as it deems appropriate. It also makes recommendations to our board regarding the adoption, amendment and rescission of equity-based incentive compensation plans. Our Compensation Committee also administers the 2001 Employee Equity Incentive Plan and the Long-Term Incentive Plan, under which incentive compensation may be awarded to executive officers.

Consistent with its charter, during 2005, our Compensation Committee made all decisions relating to executive officer compensation, including the award of 2004 annual incentive bonuses, payable in 2005, and the determination of bonus award criteria and levels for the 2005 annual incentive bonuses and the long-term incentive awards.

The objectives of our Compensation Committee in establishing executive compensation are:

 
·
to offer levels of compensation substantially equivalent to those offered by other companies in similar businesses that we consider to be competitors for executive talent,

 
·
to compensate executives based on each executive’s level of responsibility and contribution to our business goals,

 
·
to link compensation with the independent individual goals for each executive as well as the financial performance of the entire company and the financial performance of the business unit for which the executive is responsible, and

 
·
to align the interests of our executives with the interests of our stockholders.

To achieve these objectives, our executive compensation program, which includes our Chief Executive Officer, was developed with the assistance of an independent compensation advisor retained by our Compensation Committee. Our program consists principally of base salary, annual incentive cash bonuses, long-term incentive plan awards payable in restricted stock, deferred stock units ,   stock options (both incentive and non-qualified) and/or long-term incentive cash bonuse s , as described below.

Base Salary . Our Compensation Committee evaluates executive base salaries by level of responsibility, individual performance and our corporate performance, as well as by reference to competitive factors in the marketplace for key executives. The committee authorized a salary increase budget, net of the salary increases for executive officers, of 3.3% for 2005 to be assigned in the discretion of ou r Chief Executive Officer.

For 2005, our Chief Executive Officer recommended to our Compensation Committee to raise the annual salary of only one of the executive officers, ou r former Senior Vice President and Chief Financial Officer, Christian G. Farman, to $310,000 from $ 265,000, based upon Mr. Farman’s efforts during 2004 to upgrade and energize our finance function and to increase the rigor of our financial reporting discipline . No increase was made for 2005 to the annual salary of ou r former Senior Vice President and Chief Operating Officer, Thomas W. Vaughn, who joined our company on August 30, 2004 at an annual salary of $ 330,000 . Our Vice President and General Counsel, David F. Morris, joined the company on January 10, 2005 at an annual salary of $210,000. Thomas E. Vossman was appointed as our Senior Vice President and Chief Operating Officer on May 2, 2005 at an annual salary of $280,000 after joinin g our

- 14 -


company in January 2005 as vice president of the southwest region of our rehabilitation business . The annual base salaries of Messrs. Vossman, Morris and Vaughn were established based upon their past work experiences and competitive market data for their counterparts at comparable companies.  

For 2005, the annual salary of our Chief Executive Officer, Thomas S. Rooney, Jr., was increased to $630,000 from $590,000 for 2004. In approving such increase, the Compensation Committee reviewed Mr. Rooney’s individual performance during 2004 as well as our company’s overall performance. While our financial results for 2004 were considerably below our board’s expectations, our board and our Compensation Committee viewed 2004 as a turnaround year and believed that Mr. Rooney made significant progress during the year in implementing our strategic planning initiatives and positioning our company to realize its full potential.  

Annual Incentive Cash Bonuses . For 2005, our   executive officers and other key employees   were eligible to receive annual incentive cash bonuses if our company exceeded the threshold net income level established in our 2005 Management Annual Incentive Plan . In 2005, the Compensation Committee sought to more directly align payouts under the plan to our overall financial performance by relating   the amount of the total bonus pool to a targeted net income level. To the extent we did not achieve the targeted net income level, the amount of the bonus pool was reduced.   The Compensation Committee believes that this mechanism of funding the bonus pool advances the interests of our company and stockholders by more directly aligning the interests of our key employees with those of our stockholders. For 2005, the amount of the bonuses awarded under the plan also was based o n a number of independent individual performance components and, for key employees at our business units, o n the financial performance of the employee’s particula r business unit . These threshold levels and the individual and business unit performance goals were set for each of the participants in the first half of the year.

For 2005, the mid-point target for annual incentive compensation was set at 70% of the annual salary of Mr. Rooney, 50% of the respective annual salaries of Messrs. Farman and Vaughn (who were not eligible for their 2005 annual bonuses because of the termination of their employment prior to the end of the year), 50% of the annual salary of Mr. Vossman and 40% of the annual salary of Mr. Morris, with an opportunity to receive   a bonus of up to   twice the mid-point target percentages based upon the level of each executive’s performance during the year . Each of the computed bonuses is subject to reduction in the sole discretion of the Compensation Committee.
 
For 2005, Messrs. Rooney, Vossman and Morris were awarded bonuses in the amounts of $75,000 , $50,000 and $40,000, respectively, under the plan. The Compensation Committee believes that these partial bonus payments reflect the objective of the Compensation Committee to more directly align annual incentive payouts to our overall financial performance, as described above. While the financial results of our rehabilitation and Tite Liner® businesses for 2005 matched or exceeded the expectations of our board and our Compensation Committee, the results of our tunneling business were considerably lower than expected, which resulted in our overall financial performance falling below expectations. Notwithstanding that our overall financial performance in 2005 did not meet expectations, the Compensation Committee believes that management made continued progress during the year in strengthening our company and implementing our strategic initiatives, and approved the cash bonus payments to our executive officers in recognition of their efforts . The annual cash bonuses are intended to qualify as “qualified performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended, by virtue of the Compensation Committee providing performance criteria for these annual cash bonuses as awards under our Long-Term Incentive Plan.

Long-Term Executive Cash Performance Awards. The purpose of the Long-Term Cash Performance Program is to provide our senior management with long-term incentive compensation in the form of cash based on the level of achievement of financial and other pre-established performance criteria over a three-year performance period. Each year a new three-year performance period commences with differen t performance criteria and/or targets set for each such period. Our Long-Term Cash Performance

- 15 -


Plan focuses the interests of our key executives on one or more of the key measures of our financial success as determined by our Compensation Committee over the longer term than the annual cash bonuses. The key performance criteria from which our Compensation Committee can choose are embodied in the Long-Term Incentive Plan, which our stockholders have previously approved.

For the three-year performance period starting in 2005 and ending in 2007, the Compensation Committee established a target payout of $370,000 for Mr. Rooney, a target payout of $102,000 for each of Messrs. Farman and Vaughn (who will not be eligible for any part of these award s because of the termination of their employment prior to the end of the perio d ), a target payout of $102,000 for Mr. Vossman and a target payout of $53,000 for Mr. Morris. The actual payout amounts are to be calculated based on a stockholders’ equity target for the three-year period ending December 31, 2007 and may be reduced in the sole discretion of the Compensation Committee.

Long-Term Equity Incentive Awards. The primary purpose of our equity incentive program is to align the interests of our key employees, including the executive officers, more closely with the interests of our stockholders by offering these key employees an opportunity to benefit from increases in the market price of our common stock. Our equity incentive program provides long-term incentives that have enabled us to attract and retain key employees by encouraging their ownership of our common stock.

Each of our executive officers wa s granted stock options and restricted stock during 2005. Messrs. Rooney, Vossman and Morris each received seven-year options to purchase 95,000, 26,000 and 13,500 shares, respectively, of our common stock, vesting 25% upon grant and 25% annually thereafter for the next three years. The exercise price for the options was set at the fair market value of our stock on the date of grant. Messrs. Rooney, Vossman and Morris also were awarded 14,000, 4,000 and 2,000 shares, respectively, of restricted stock that will vest fully on the third anniversary date of the award if their employment with us has not terminated as of tha t date and if a pre-established net income goal fo r the performance period beginning on May 1, 2005 and ending on April 30, 2006 is achieved. Each of the restricted stock awards are intended to qualify as “qualified performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code by virtue of the Compensation Committee setting performance criteria for these restricted awards under our Long-Term Incentive Plan.

Our former Senior Vice President and Chief Financial Officer, Christian G. Farman, also was granted 26,000 stock options and 4,000 shares of restricted stock unde r the same terms described above during 2005 . The 19,500 options that were unvested and unexercised as of December 28, 2005 were cancelled. The 6,500 options that were vested and unexercised as of December 28, 2005 were exercised by Mr. Farman on February 24, 2006. The 4,000 restricted shares were cancelled as of December 28, 2005.

Other Compensation Matters . Executive officers may choose to defer up to specified maximum amounts of compensation by contributing those amounts to our non-qualified, deferred compensation plan for key employees. This plan allows for base salary deferral, subject to legal limitations, of up to 15% of base salary, and bonus deferral of up to 50% of bonus amounts. Under the plan, we will match the first 3% of contributions at a 100% rate, and the next 2% of contributions at a 50% rate, when aggregated with any matching contributions made under our 401(k) Profit-Sharing Plan (limited to compensation up to $210,000 per annum for 2005). Contributions in the non-qualified, deferred compensation plan are adjusted to match the performance of participant-selected indices. Account balances will accrue for each participant based on the amount of the participant’s deferrals into the account and the investment performance of his or her selected indices. Participants will be paid their account balances after termination of their employment with our company. During 2005, Mr. Rooney deferred $122,962 of his compensation under our non-qualified, deferred compensation plan, which amount does not include $3,550 in company-matching contributions that we contributed to his account under the plan during 2005.

- 16 -


Section 162(m) of the Internal Revenue Code of 1986, as amended, generally limits federal income tax deductions for compensation to $1 million per year for our Chief Executive Officer and our four other most highly compensated executive officers, but it contains an exception for performance-based compensation that satisfies certain conditions. Our Long-Term Incentive Plan is intended to allow us to pay performance-based compensation as defined in Section 162(m). Under our Long-Term Incentive Plan, our Compensation Committee designates participants in various incentive programs for each fiscal year or other period set by our Compensation Committee. Each incentive program can have its own specific performance goals or targets and performance period. Our Compensation Committee establishes objective performance goals based upon one or more of the following criteria, individually or in combination, adjusted in the manner our Compensation Committee determines in its sole discretion:

·   stock price
·   earnings per shar e
·   sales
·   free cash flo w
·   return on equity
·   net incom e
·   book value
·   individual performance
·   expense management
·   business unit performance
 
The payment of an incentive program award under our Long-Term Incentive Plan may be reduced by our Compensation Committee in its sole discretion, and the granting of awards is subject to the discretion of our Compensation Committee.

In making compensation decisions, we consider the net cost of compensation. We also consider whether it is practicable, and consistent with other compensation objectives, to qualify our incentive compensation under the applicable exemption of Section 162(m). We anticipate that deductibility of compensation payments will be one of a number of factors considered in ascertaining appropriate levels or types of compensation, and that we will make our compensation decision based upon an overall determination of what we believe to be in the best interests of our stockholders.

The foregoing report on executive compensation is provided by our Compensation Committee.

Represents grant on May 5, 2005, under our 2001 Employee Equity Incentive Plan, of options to purchase shares of our common stock. Each of the options are seven-year options, vesting 25% upon grant and 25% annually thereafter for the next three years. The exercise price for the options was set at the fair market value of our stock on the date of grant.

(2)
Amounts represent hypothetical gains that could be achieved for the respective options if exercised at the end of the option term. These gains are based on arbitrarily assumed rates of stock price appreciation of 5% and 10% compounded annually from the date the respective options are granted to their expiration date. Actual gains, if any, on stock option exercises will be dependent on, among other things, the future performance of the common stock and overall market conditions. There can be no assurance that the amounts reflected above will be achieved.

Of the options that were vested and unexercised as of December 28, 2005, 17,625 options (8,250 of the options granted in 2004 and 9,375 of the options granted in 2003) were cancelled as of that date and 6,500 options (granted in 2005) were exercised by Mr. Farman on February 24, 2006.

Long-Term Incentive Plan Awards Table

Under our Long-Term Incentive Plan, key executives designated by our Compensation Committee are eligible to earn a deferred cash incentive award based on our financial performance. Participants in the plan are eligible to earn an award after the end of each performance period. New performance periods are expected to begin each year. If our actual performance falls below certain parameters, no payouts are made.

Of our current named executive officers, only Thomas S. Rooney, Jr., our President and Chief Executive Officer, had been named as a participant in the 2003-2005 performance period and was eligible to receive an award under the plan for the period (Thomas E. Vossman, our Senior Vice President and Chief Operating Officer, and David F. Morris, our Vice President and General Counsel, did not join our company until May 2005 and January 2005, respectively). However, the performance goals established for the period had not been achieved as of December 31, 2005 and, as a result, Mr. Rooney’s award was forfeited.

The following table sets forth certain information regarding awards made to executive officers pursuant to our Long-Term Incentive Plan during the last fiscal year for the 2005-2007 performance period.

P ERFORMANCE G RAPH

The following performance graph compares the total stockholder return on our common stock to the S&P 500 Index and a composite peer group index for the past five years. Our peer group index is comprised of the following six companies:

 
·
INEI Corporation, f/k/a Insituform East Incorporated
 
·
Michael Baker Corporation
 
·
Granite Construction, Inc.
 
·
Fluor Corporation
 
·
Jacobs Engineering Group, Inc.
 
·
Foster Wheeler Corp.

As of September 5, 2003, we acquired the business of Insituform East Incorporated, including selected assets.

At the end of 2000, Fluor Corporation, a publicly-traded company, completed a reverse spin-off of one of its businesses that resulted in two publicly-traded companies. As a result, Fluor Corporation, the company that now contains the segment relevant to our peer group index, is only included in the peer group index for 2001 through 2005, the period following the spin-off.

The graph assumes that $100 was invested in our common stock and each index on December 31, 2000 and that all dividends were reinvested.

P ROPOSAL 2: A PPROVAL OF THE 2006 N ON -E MPLOYEE D IRECTOR E QUITY I NCENTIVE P LAN
 
Our board of directors has adopted, subject to stockholder approval, the 2006 Non-Employee Director Equity Incentive Plan (the “2006 Director Incentive Plan”). If the 2006 Director Incentive Plan is approved by stockholders, our board of directors intends to terminate the Amended and Restated 2001 Non-Employee Director Equity Incentive Plan (the “2001 Director Incentive Plan”), which would otherwise expire on May 10, 2011, and cancel the authority to grant new awards under the 2001 Director Incentive Plan. There are currently approximately 60,600 shares which are authorized for issuance, and not otherwise subject to an outstanding award, under the 2001 Director Incentive Plan which will no longer be available for future awards upon the approval of the 2006 Director Incentive Plan.

The 2006 Director Incentive Plan provides for the granting of non-qualified stock options and stock units to our directors who are not company employees. Our board of directors believes that the plan advances the interests of our company and stockholders by increasing the ownership interest of the directors in our company, thus aligning their interests in our financial performance more directly to those of our stockholders and providing them an incentive to serve as a director over the long term.

The maximum number of shares of our common stock that is being authorized for issuance under the 2006 Director Incentive Plan is 200,000, subject to adjustment in the event of any subsequent change in the number of issued shares of our common stock without new consideration to our company, such as in a stock dividend, stock split or similar issuance.

- 26 -



The complete text of the 2006 Director Incentive Plan is attached as Appendix B . The following summary of the plan is subject to the provisions contained in the complete text of the plan.
 
Description of the 2006 Director Incentive Plan
 
Administration. The 2006 Director Incentive Plan will be administered by our board of directors. Our board of directors will have exclusive authority to interpret and administer the plan, to establish, amend and rescind any rules and regulations relating to the plan and to take all steps and make all determinations necessary or advisable for the administration of the plan.

Eligibility.   All of our directors who are not employed by us or any of our subsidiaries or affiliates will be eligible to participate.

Shares Subject to the Plan.   An aggregate of 200,000 shares of our common stock is being authorized for issuance under the 2006 Director Incentive Plan, subject to adjustment in the event of any subsequent change in the number of issued shares of our common stock without new consideration to our company, such as in a stock dividend, stock split or similar issuance.

Types of Awards. Non-qualified stock options and stock units may be granted.

Non-Qualified Stock Options. Non-qualified stock options are non-statutory options to purchase shares of our common stock that are not intended to qualify under Section 422 of the federal tax code. Upon the exercise of a non-qualified stock option, shares of our common stock may be purchased at a price established on the date of grant by our board of directors in its sole discretion. Our board of directors will determine the terms and conditions of any stock options and the periods during which the stock options will be exercisable.

Stock Units. Stock units represent the right to receive shares of our common stock at a time or upon terms designated in the award agreement. Our board of directors may in its discretion provide in the award agreement that the holder will be entitled to payments in cash or adjustments in the number of stock units equivalent in value to the dividends on our common stock as if the stock units were shares of common stock at our dividend payment dates.

No Rights as a Stockholder. Holders of stock options or stock units will not have any rights as a stockholder on the basis of the awards.

Effective Date, Amendments and Duration.   The 2006 Director Incentive Plan will be effective upon the approval of our stockholders at the 2006 annual meeting.

Our board of directors may amend or modify the 2006 Director Incentive Plan at any time except an amendment or modification (i) changing eligibility requirements under the plan, (ii) increasing the number of shares of common stock that may be issued under the plan or (iii) increasing the amount or type of benefits that may be granted under the plan, requires the prior approval of our stockholders. The board may not reduce the amount or change the terms and conditions of any outstanding option or stock unit without the holder’s prior consent.

The 2006 Director Incentive Plan will be effective for a period of ten years from the effective date unless our board of directors terminates the plan earlier.

- 27 -

 
Federal Tax Consequences
 
No income will be realized upon grant by the holders of non-qualified stock options or stock units, and we will not be entitled to a deduction at such time.

Upon the exercise of a non-qualified stock option, the excess, if any, of the fair market value of the stock on the date of exercise over the purchase price is ordinary income to the holder as of the date of exercise. We generally will be entitled to a deduction equal to such excess amount in the year of exercise.

A holder will realize income as a result of an award of stock units at the time shares of common stock are issued in an amount equal to the fair market value of such shares at the date of issuance. We will be entitled to a corresponding deduction equal to the income realized in the year that the shares are issued.

The tax consequences to the holder of an award described above assume that, to the extent any award under the plan is subject to the requirements of Section 409A of the federal tax code, such award will comply with that section. In the event any such award that is subject to Section 409A was determined not to be in compliance with the section, the holder could be subject to earlier taxation, a penalty tax of 20% of the amount includible in gross income, and interest on federal income taxes that would have been payable if the amount were taxable when first deferred.

New Plan Benefits

Currently, the seven non-employee members of our board of directors will be eligible to participate in the 2006 Director Incentive Plan. Awards will be granted under the plan in the discretion of our board of directors and may vary year to year. Thus, the amount of stock options and/or stock units to be granted under the plan is not determinable as of the date of this proxy statement. However, please see “Director Compensation” above for an example of awards that would have been granted under the plan had it been in effect during 2005.

The fair market value per share of our common stock for all purposes under the plan will be the closing selling price per share on The Nasdaq Stock Market on the determination date. On March 1, 2006, the fair market value per share of our common stock was $27.27.

Required Vote for Approval

The required vote for approval of the 2006 Director Incentive Plan is a majority of the shares of our common stock cast on this proposal at the annual meeting.

Our board of directors recommends a vote “FOR” the approval of the 2006 Non-Employee Director Equity Incentive Plan.

P ROPOSAL 3: A PPROVAL OF THE 2006 E MPLOYEE E QUITY I NCENTIVE P LAN

Our board of directors has adopted, subject to stockholder approval, the 2006 Employee Equity Incentive Plan (the “2006 Employee Incentive Plan”). If the 2006 Employee Incentive Plan is approved by stockholders, our board of directors intends to terminate the Amended and Restated 2001 Employee Equity Incentive Plan (the “2001 Employee Incentive Plan”), which would otherwise expire on May 10, 2011, and cancel the authority to grant new awards under the 2001 Employee Incentive Plan. There are currently approximately 426,000 shares which are authorized for issuance, and not otherwise subject to an outstanding award, under the 2001 Employee Incentive Plan which will no longer be available for future awards upon the approval of the 2006 Employee Incentive Plan.

- 28 -


The 2006 Employee Incentive Plan provides for the granting of stock options and other stock-based awards to our key employees. Our board of directors believes that it is in our best interest to have sufficient shares available under the plan for awards to key employees, whose talents and special efforts are essential to our continued progress. In addition, our board of directors believes that the plan advances the interests of our company and stockholders by encouraging key employees to acquire an ownership interest in our company, thus aligning their interests in our financial performance more directly to those of our stockholders and providing them an incentive to remain employees over the long term.

The maximum number of shares of our common stock that is being authorized for issuance under the 2006 Employee Incentive Plan is 2,000,000, subject to adjustment in the event of any subsequent change in the number of issued shares of our common stock without new consideration to our company, such as in a stock dividend, stock split or similar issuance.

The complete text of the 2006 Employee Incentive Plan is attached as Appendix C . The following summary of the plan is subject to the provisions contained in the complete text of the plan.
 
Description of the 2006 Employee Incentive Plan
 

Administration. The 2006 Employee Incentive Plan will be administered by our board of directors or our Compensation Committee (the “Administrator”). The Administrator will have exclusive authority to interpret and administer the plan, to establish appropriate rules relating to the plan, to delegate some or all of its authority under the plan and to take all such steps and make all such determinations in connection with the plan and the benefits granted pursuant to the plan as it may deem necessary or advisable.

Eligibility.   Officers and key employees of our company and subsidiaries will be eligible to participate. The Administrator has the sole discretion to designate which employees among the eligible participants will receive awards under the plan.

Shares Subject to the Plan.   An aggregate of 2,000,000 shares of our common stock is being authorized for issuance under the 2006 Employee Incentive Plan, subject to adjustment in the event of any subsequent change in the number of issued shares of our common stock without new consideration to our company, such as in a stock dividend, stock split or similar issuance.

Types of Awards. Stock appreciation rights, restricted stock, performance awards, stock options and stock units may be granted.  

Stock Appreciation Rights. Stock appreciation rights entitle the holder to receive a payment equal to the difference between the fair market value of our common stock at the time of exercise of the stock appreciation right and the base price of the stock appreciation right established by the Administrator at the time of grant. At the time of grant, the Administrator may establish a maximum amount per share which will be payable upon exercise of a stock appreciation right, and may determine whether a stock appreciation right may be exercised (i) in conjunction with the exercise of a stock option, (ii) upon lapse of a stock option and/or (iii) independent of the exercise of a stock option. In the Administrator’s discretion, the value of a stock appreciation right may be paid in cash or common stock, or a combination thereof. The Administrator will establish the term of any stock appreciation rights provided that stock appreciation rights may not be exercised more than ten years from the date of grant.
 
Restricted Stock. Restricted stock are shares of our common stock that are subject to the restrictions or conditions specified by the Administrator at the time of grant. The Administrator may issue shares of restricted stock either as a stock bonus or at a purchase price below the fair market value

- 29 -


of our stock on the date of grant. During the period that the stock is restricted, holders will be entitled to receive all dividends and other distributions made in respect of the restricted stock and to vote the restricted stock without limitation. The maximum number of shares of restricted stock that may be awarded in any calendar year to any individual may not exceed 50,000 shares, subject to the adjustment provisions of the plan.

Performance Awards. In the discretion of the Administrator, performance awards entitle the holder to receive shares of our common stock or cash, or both, upon the achievement of certain pre-established performance criteria (such as return on average total capital employed, earnings per share or increases in share price) during a performance period that may not exceed five years. The holder has no right to receive dividends on or to vote shares subject to performance awards until the shares are actually earned and issued.
 
Stock Options. Stock options entitle the holder to purchase common stock at a purchase price established by the Administrator on the date of grant. The purchase price of any stock option may not be less than the fair market value of our common stock on the date of grant. The Administrator will determine the terms and conditions of such stock options and the times at which such stock options will be exercisable. The maximum number of shares subject to a stock option that may be awarded in any calendar year to any individual may not exceed 200,000 shares, subject to the adjustment provisions under the plan. In addition, no incentive stock option may be granted to any individual if the aggregate fair market value of common stock underlying all incentive stock options held by the individual that are exercisable for the first time in any calendar year exceeds $100,000.
 
Stock Units. Stock units represent the right to receive shares of our common stock at a time or upon terms designated in the award agreement. The Administrator may in its discretion provide in the award agreement that the holder will be entitled to payments in cash or adjustments in the number of stock units equivalent in value to the dividends on our common stock as if the stock units were shares of common stock at our dividend payment dates.

No Rights as a Stockholder.   Except in the case of awards of restricted stock, holders of awards under the plan will not have any rights as a stockholder on the basis of the awards.

Effective Date, Amendments and Duration.   The 2006 Employee Incentive Plan will be effective upon approval of our stockholders at the 2006 annual meeting.

Our board of directors may amend or modify the 2006 Employee Incentive Plan at any time except an amendment or modification (i) increasing the number of shares of common stock that may be issued under the plan, (ii) increasing the amount or type of benefits that may be granted under the plan or (iii) modifying the eligibility requirements for benefits under the plan, requires the prior approval of our stockholders. The Administrator may not reduce the amount, or change the terms and conditions, of any existing award without the holder’s prior consent.

The 2006 Employee Incentive Plan will be effective for a period of ten years from the effective date unless our board of directors terminates the plan earlier.
 
Federal Tax Consequences
 
A participating employee will not realize income on the grant of stock options or stock appreciation rights or the award of restricted stock or stock units, and we will not be entitled to a deduction at such time. If a holder exercises an incentive stock option and does not dispose of the shares acquired within two years from the date of the grant, or within one year from the date of exercise of the stock option, no ordinary income will be realized by the holder at the time of exercise, and we will not be

- 30 -


entitled to a deduction by reason of the exercise. The holder will realize capital gain or loss upon the sale of the acquired shares equal to the difference between the sale price and the purchase price for the shares. If a holder disposes of the shares acquired pursuant to an incentive stock option within two years from the date of grant of the stock option or within one year from the date of exercise of the stock option, the holder will realize ordinary income at the time of disposition equal to the excess, if any, of the lesser of (a) the amount realized on the disposition or (b) the fair market value of the shares on the date of exercise, over the holder’s basis in the shares. We generally will be entitled to a deduction in an amount equal to such income in the year of the disqualifying disposition, except to the extent, if any, that such deduction may be limited under Section 162(m) or Section 280G of the federal tax code. In addition, the holder will realize capital gain or loss on any excess of the sale price over the fair market value on the exercise date.

Upon the exercise of a non-qualified stock option or the surrender of a stock appreciation right, the excess, if any, of the fair market value of the stock on the date of exercise over the purchase price or base price, as the case may be, is ordinary income to the holder as of the date of exercise. We generally will be entitled to a deduction equal to such excess amount in the year of exercise, except to the extent, if any, that such deduction may be limited under Section 162(m) or Section 280G of the federal tax code.

Subject to a voluntary election by the holder under Section 83(b) of the federal tax code, a holder of restricted shares of common stock will realize income as a result of the award of such shares at the time the restrictions expire on such shares. An election pursuant to Section 83(b) of the federal tax code would cause the holder to realize income in the year in which such award was granted. The amount of income realized will be the difference between the fair market value of the shares on the date such restrictions expire (or on the date of issuance of the shares, in the event of a Section 83(b) election) over the purchase price, if any, of such shares. We generally will be entitled to a deduction equal to the income realized in the year in which the holder is required to report such income, except to the extent, if any, that such deduction may be limited under Section 162(m) or Section 280G of the federal tax code.

A holder will realize income as a result of a performance award at the time the award is paid or made available. The amount of income realized by the holder will be equal to the fair market value of the shares on the date of issuance, in the case of a stock award, and to the amount of the cash paid, in the event of a cash award. We will be entitled to a corresponding deduction equal to the income realized in the year of such issuance or payment, except to the extent, if any, that such deduction may be limited under Section 162(m) or Section 280G of the federal tax code.

A holder will realize income as a result of an award of stock units at the time shares of common stock are issued in an amount equal to the fair market value of such shares at that time. We will be entitled to a corresponding deduction equal to the income realized in the year of such issuance, except to the extent, if any, that such deduction may be limited under Section 162(m) or Section 280G of the federal tax code.

The tax consequences to the holder of an award described above assume that, to the extent any award under the plan is subject to the requirements of Section 409A of the federal tax code, such award will comply with that section. In the event any such award that is subject to Section 409A was determined not to be in compliance with the section, the holder could be subject to earlier taxation, a penalty tax of 20% of the amount includible in gross income, and interest on federal income taxes that would have been payable if the amount were taxable when first deferred.

New Plan Benefits

Currently, approximately 70 employees will be eligible to participate in the 2006 Employee Incentive Plan. The Administrator will determine annually the award recipients and the actual awards granted under the plan. As these awards are discretionary, the amount of awards to be granted under the plan is not determinable as of the date of this proxy statement. However, please see the “Summary

- 31 -


Compensation Table” above for an example of awards that would have been granted under the plan had it been in effect during 2005.

The fair market value per share of our common stock for all purposes under the plan will be the closing selling price per share on The Nasdaq Stock Market on the determination date. On March 1, 2006, the fair market value per share of our common stock was $27.27.

Required Vote for Approval

The required vote for approval of the 2006 Employee Incentive Plan is a majority of the shares of our common stock cast on this proposal at the annual meeting.

Our board of directors recommends a vote “FOR” the approval of the 2006 Employee Equity Incentive Plan.

P ROPOSAL 4: A PPROVAL OF THE 2006 E XECUTIVE P ERFORMANCE P LAN

Our board of directors has adopted, subject to stockholder approval, the 2006 Executive Performance Plan (the “Executive Performance Plan”). Pursuant to Section 162(m) of the federal tax code, a plan setting forth the criteria that will be used by the board of directors or the Compensation Committee in establishing objective goals for earning incentive compensation that will be deemed to be performance-based under Section 162(m) must be approved by the stockholders at least every five years. Our Long-Term Incentive Plan, which currently sets forth the criteria used by the board or the committee to set goals for performance-based compensation, was last approved by the stockholders at the 2001 annual meeting. The Executive Performance Plan is being submitted to the stockholders at the 2006 annual meeting to allow continued compliance with Section 162(m).

Under Section 162(m) of the federal tax code, the amount of our deduction for a fiscal year relating to compensation for certain executive officers is limited to $1,000,000 unless the compensation is deemed to be performance based. Our board of directors believes that approval of the Executive Performance Plan advances the interest of our company and stockholders by providing for the payment of incentive compensation that will meet the Section 162(m) requirements for performance-based compensation thereby assuring that the compensation paid or issued will be fully deductible by our company for federal tax purposes.

The complete text of the Executive Performance Plan is attached as Appendix D . The following summary of the plan is subject to the provisions contained in the complete text of the plan.

Description of the Executive Performance Plan

Administration and Eligibility. Under the Executive Performance Plan, which will be administered by our Compensation Committee, the chief executive officer and any other executive officer who is required to be named in the summary compensation table of our proxy statement will be eligible to participate in the plan and receive performance-based compensation in the form of cash bonuses or in the grant of an award (other than a stock option) under any of our equity incentive plans (such as the 2006 Employee Incentive Plan). Other employees will also be eligible to receive incentive awards for a particular fiscal year or other performance period, but the incentive awards for these employees are not required to be paid or issued pursuant to this plan by Section 162(m).

Performance Criteria. Our Compensation Committee will establish objective performance goals in writing not later than 90 days after the beginning of each fiscal year or other performance period for the payment of incentive compensation. The performance goals will be established by the committee based

- 32 -


upon one or more of the following criteria, individually or in combination, adjusted in such manner as the committee shall determine in its sole discretion: (i) stock price; (ii) sales; (iii) return on equity; (iv) book value; (v) expense management; (vi) earnings per share; (vii) free cash flow; (viii) net income; (ix) return on assets; (x) individual performance; and (xi) business unit performance. The payment of any award under the Executive Performance Plan may be reduced by the committee in its sole discretion based upon such factors as the committee shall determine.

The maximum aggregate amount of compensation that may be paid to a participant in any fiscal year pursuant to one or more awards under the plan may not exceed the Maximum Amount (as defined below) for such fiscal year. For purposes of this plan, the Maximum Amount for a fiscal year shall be $3,220,000 for the 2006 fiscal year, and, for each succeeding fiscal year, 110% of the Maximum Amount for the immediately preceding year. If the Maximum Amount (including carryforwards under this sentence) for a fiscal year exceeds the amount paid to a participant in that year, the excess shall be carried forward and added to the Maximum Amount for the succeeding fiscal year.
 
Amendments and Termination. The Executive Performance Plan may be amended or terminated at any time by our board of directors in its sole and absolute discretion.

Federal Tax Consequences

Upon the payment of a cash bonus pursuant to the Executive Performance Plan, a participant will realize ordinary income as of the date the bonus is payable to the participant and we will be entitled to a deduction at that time. Upon the grant of a performance-based award under any of our equity incentive plans, a participant will realize income with respect to a particular award, and we will be entitled to a corresponding deduction, in the same manner as described above under “Proposal 3: Approval and Adoption of the 2006 Employee Equity Incentive Plan - Federal Tax Consequences.”

New Plan Benefits

Currently, three employees will be eligible to participate in the Executive Performance Plan. Our Compensation Committee will determine annually the award recipients and the actual awards granted under the plan. As these awards are discretionary, the amount of awards to be granted under the plan is not determinable as of the date of this proxy statement. However, please see the “Long-Term Incentive Plan Awards Table” above for an example of awards that would have been granted under the plan had it been in effect during 2005.

The fair market value per share of our common stock for all purposes under the plan will be the closing selling price per share on The Nasdaq Stock Market on the determination date. On March 1, 2006, the fair market value per share of our common stock was $27.27.

Required Vote for Approval

The required vote for approval of the 2006 Executive Performance Plan is a majority of the shares of our common stock cast on this proposal at the annual meeting.

Our board of directors recommends a vote “FOR” the approval of the 2006 Executive Performance Plan.

PricewaterhouseCoopers   LLP served as our independent auditors for the year ended December 31, 2005. Representatives of PricewaterhouseCoopers   LLP are expected to be present at our annual meeting to respond to appropriate questions from our stockholders and to make statements if they so desire.

Our board of directors recommends a vote “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditors for the year ending December 31, 2006.

O THER M ATTERS

The board does not know of any other matters that may be brought before the annual meeting. However, if any other matters are properly presented for action, it is the intention of the persons named on the accompanying proxy card to vote the shares represented thereby in accordance with their judgment on such matters.

S TOCKHOLDER P ROPOSALS

Our by-laws provide that, in order for a stockholder to nominate a candidate for director or to bring other business before a meeting of stockholders, the stockholder must have given timely notice thereof in writing to our Secretary. We must receive stockholder proposals intended to be presented at an annual meeting at least 120 days (which for the 2007 annual meeting would be November 10, 2006) prior to the anniversary date on which we first mailed our proxy materials for the preceding year’s annual meeting of stockholders, in order to be considered for inclusion in our proxy statement relating to the meeting. Stockholder proposals that do not appear in the proxy statement may be considered at a meeting of stockholders only if written notice of the proposal is delivered to or mailed and received by our corporate Secretary at our principal executive office not less than 90 days nor more than 120 days (which for the 2007 annual meeting of stockholders would be January 26, 2007 and December 27, 2006, respectively) prior to the anniversary date of the preceding year’s annual meeting of stockholders.

However, if the date of the annual meeting is advanced or delayed by more than 30 days compared to the date of the preceding year’s annual meeting, notice by the stockholder to be timely made must be received not later than the close of business on the later of:

 
·
the ninetieth day prior to the meeting, or
 
·
the tenth day following the date on which the date set for the meeting is first announced publicly.

- 34 -


Notwithstanding the foregoing requirements, a proxy may confer discretionary authority to vote on any stockholder proposal, provided that such proposal is received at least 45 days (which for the 2007 annual meeting of stockholders would be January 24, 2007) prior to the anniversary date on which we first mailed our proxy materials for the preceding year’s annual meeting of stockholders.

Any written notice of a stockholder proposal must include the information required by our by-laws and, in the case of a notice of nomination, all information relating to each person whom the stockholder proposes to nominate for election or reelection as a director, that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, as amended (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected).

If a stockholder fails to notify us within the time limits described above of an intent to present a nomination or proposal for a stockholder vote at our 2007 annual meeting of stockholders, we will declare the nomination or business to be not properly brought before the meeting and, therefore, the nomination will be disregarded or the business will not be transacted. The foregoing requirements are separate from and in addition to the requirements of the Securities and Exchange Commission that a stockholder must meet to have a proposal included in our proxy statement.

S TOCKHOLDER C OMMUNICATIONS W ITH D IRECTORS

Our board has an informal process in place for our stockholders to communicate with directors. Any stockholder wishing to contact our board or one of our directors can write to:

2006 NON-EMPLOYEE DIRECTOR EQUITY INCENTIVE PLAN


1.   Purpose and Nature of Plan. The purpose of this 2006 Non-Employee Director Equity Incentive Plan (the “ Plan ”) of Insituform Technologies, Inc. (the “ Company ”) is to increase the ownership interest in the Company of non-employee directors whose services are considered essential to the Company’s continued progress and thus provide a further incentive to serve as a director of the Company.

2.   Administration . The Plan shall be administered by the Board of Directors of the Company (the “ Board ”). Subject to the provisions of the Plan, the Board shall have exclusive authority to interpret and administer the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to take all steps and make all determinations necessary or advisable for the administration of the Plan. The determination of the Board in the administration of the Plan shall be conclusive and binding upon all persons, including without limitation the Company, its stockholders and persons granted options or other benefits under the Plan. The officers of the Company shall be authorized to implement the Plan in accordance with its terms and to take such actions of a ministerial nature as shall be necessary to effectuate the intent and purposes of the Plan.

3.   Participants . Directors of the Company who are not employees of the Company (or any affiliate of the Company) during a calendar year shall be eligible to participate in awards made pursuant to the Plan with respect to such calendar year (“ Eligible Directors ”).

4.   Shares Subject to the Plan . Subject to adjustment as provided in Section 7 (relating to adjustment for changes in capital stock), an aggregate of 200,000 shares of the Company’s Class A common shares, $0.01 par value (“ Common Stock ”), shall be available for issuance under the Plan. The shares of Common Stock issued under the Plan may be made available from authorized but unissued shares or from shares re-acquired by the Company, including shares purchased in the open market or in private transactions. If any option granted under the Plan shall expire or terminate for any reason without having been exercised in full, the shares subject to, but not delivered under, such option may again become available for the grant of other options or Stock Units under the Plan. If any Stock Unit granted under the Plan shall be forfeited or cancelled for any reason, the shares subject to, but not delivered under, such Stock Unit may again become available for the grant of other options or Stock Units under the Plan.

5.   Awards of Benefits . The Board of Directors may, in its sole discretion, grant benefits in accordance with the Plan to Eligible Directors, and establish the timing, pricing, amount and other terms and conditions of such grants, which need not be uniform with respect to the various participants or with respect to different grants to the same participant.  

6.   Types of Benefits . The following benefits may be granted under the Plan: (i) nonqualified stock options (“ NQSOs ”); and (ii) Stock Units, as described below.

(a)   Stock Options . NQSOs are nonqualified stock options to purchase shares of Common Stock at purchase prices established by the Board of Directors on the date the options are

B-1
 


granted, subject to such terms and conditions set forth in an option agreement as may be established by the Board of Directors in its sole discretion. The purchase price may be paid (i) by check, (ii) in the discretion of the Board of Directors, by the delivery of shares of Common Stock of the Company owned by the participant for at least six (6) months or (iii) in the discretion of the Board of Directors, by a combination of any of the foregoing, in the manner provided in the option agreement.

(b)   Stock Units. A Stock Unit represents the right to receive a share of Common Stock from the Company at a designated time in the future, subject to such terms and conditions set forth in a Stock Unit agreement as may be established by the Board of Directors in its sole discretion. The participant generally does not have the rights of a stockholder until receipt of the Common Stock. The Board of Directors may in its discretion provide for payments in cash, or adjustment in the number of Stock Units, equivalent to the dividends the participant would have received if the participant had been the owner of shares of Common Stock instead of the Stock Units.

7.   Adjustment Provisions . If the Company shall at any time change the number of issued shares of Common Stock without new consideration to the Company (such as by stock dividends or stock splits), the total number of shares of Common Stock reserved for issuance under the Plan shall be appropriately adjusted, and the number of shares of Common Stock covered by each outstanding option or Stock Unit shall be appropriately adjusted so that the aggregate consideration payable to the Company and the aggregate value of each such option or Stock Unit shall not be changed. Written option agreements or Stock Unit agreements may also contain provisions for their continuation or for other equitable adjustments after changes in the Common Stock resulting from the Company’s reorganization, recapitalization, sale, merger, consolidation, issuance of stock rights or warrants, or similar occurrence.

8.   No Right to Continue as a Director; No Stockholder Rights . Neither the Plan, nor the granting of an option or Stock Unit, nor any other action taken pursuant to the Plan, shall constitute or be evidence of any agreement or understanding, express or implied, that the Eligible Director has a right to continue as an Eligible Director for any period of time, or at any particular rate of compensation. No Eligible Director shall have rights as a stockholder with respect to shares of Common Stock covered by options or Stock Units granted hereunder until the date of the issuance of a stock certificate therefor.

9.   Amendment; Governing Law . The Board may revise or amend the Plan in any respect whatsoever; provided, that, without approval of the stockholders of the Company, no revision or amendment shall (i) change the selection or eligibility requirements under the Plan, (ii) increase the number of shares of Common Stock that may be issued under the Plan or (iii) increase the amount or type of benefits that may be granted under the Plan. No action authorized by this paragraph shall reduce the amount of any existing option or Stock Unit or change the terms and conditions thereof without the holder’s consent. The validity, construction and effect of the Plan shall be determined in accordance with the laws of the State of Missouri.

10.   Effective Date, Duration, Suspension and Termination of the Plan . The Plan will be effective immediately following approval by the stockholders of the Company at the 2006 Annual Meeting of Stockholders. The period during which option and Stock Unit grants shall be made under the Plan shall terminate on the day following the tenth anniversary of the 2006 Annual Meeting of Stockholders (unless the Plan is extended or terminated at an earlier date by stockholders); provided, (i) such termination shall not affect the terms of any then outstanding option or Stock Unit and (ii) the terms and conditions applicable to any option or Stock Unit granted within such period may thereafter be amended or modified by mutual agreement between the Company and the holder. The Board may suspend or terminate the Plan at any time and for any reason.

Appendix C



2006 EMPLOYEE EQUITY INCENTIVE PLAN


1.   Purpose and Nature of Plan . The purpose of this 2006 Employee Equity Incentive Plan (the “Plan”) of Insituform Technologies, Inc. (the “Company”) is to encourage key employees of the Company and such subsidiaries of the Company as the Administrator may designate, to acquire shares of Class A $0.01 par value common stock of the Company (“Common Stock”) or to receive monetary payments based on the value of such stock or based upon achieving certain goals on a basis mutually advantageous to such employees and the Company and thus provide an incentive for employees to contribute to the success of the Company and align the interests of key employees with the interests of the shareholders of the Company.

2.   Administration . The Plan shall be administered by the Board of Directors of the Company or the Compensation Committee of the Board of Directors (the “Administrator”).

The authority to select persons eligible to participate in the Plan, to grant benefits in accordance with the Plan, and to establish the timing, pricing, amount and other terms and conditions of such grants (which need not be uniform with respect to the various participants or with respect to different grants to the same participant), may be exercised by the Administrator in its sole discretion.

Subject to the provisions of the Plan, the Administrator shall have exclusive authority to interpret and administer the Plan, to establish appropriate rules relating to the Plan, to delegate some or all of its authority under the Plan and to take all such steps and make all such determinations in connection with the Plan and the benefits granted pursuant to the Plan as it may deem necessary or advisable. The validity, construction, and effect of the Plan shall be determined in accordance with the laws of the State of Missouri.

The Board of Directors in its discretion may delegate and assign specified duties and authority of the Administrator to any other committee and retain the other duties and authority of the Administrator to itself. Also, the Board of Directors in its discretion may appoint a separate committee of outside directors to make awards that satisfy the requirements of Section 162(m) of the Internal Revenue Code.

3.   Shares Reserved Under the Plan . Subject to the provisions of Section 12 (relating to adjustment for changes in capital stock) an aggregate of two million (2,000,000) shares of Common Stock of the Company shall be available for issuance under the Plan. The shares of Common Stock issued under the Plan may be made available from authorized but unissued shares or shares re-acquired by the Company, including shares purchased in the open market or in private transactions.

As used in this Section, the term “Plan Maximum” shall refer to the number of shares of Common Stock of the Company that are available for grant of awards pursuant to the Plan. Stock underlying outstanding options, stock appreciation rights, stock units or performance awards will reduce the Plan Maximum while such options, stock appreciation rights, stock units or performance awards are outstanding. Shares underlying expired, canceled or forfeited options, stock appreciation rights, stock units or performance awards shall be added back to the Plan Maximum. When the exercise price of stock

C-1






options is paid by delivery of shares of Common Stock of the Company, or if the Administrator approves the withholding of shares from a distribution in payment of the exercise price, the Plan Maximum shall be reduced by the net (rather than the gross) number of shares issued pursuant to such exercise, regardless of the number of shares surrendered or withheld in payment. If the Administrator approves the payment of cash to an optionee equal to the difference between the fair market value and the exercise price of stock subject to an option, or if a stock appreciation right is exercised for cash or a performance award is paid in cash, the Plan Maximum shall be increased by the number of shares with respect to which such payment is applicable. Restricted stock issued pursuant to the Plan will reduce the Plan Maximum while outstanding even while subject to restrictions. Shares of restricted stock shall be added back to the Plan Maximum if such restricted stock is forfeited or is returned to the Company as part of a restructuring of benefits granted pursuant to this Plan.

Notwithstanding the above, the maximum number of shares subject to stock options that may be awarded in any calendar year to any individual shall not exceed 200,000 shares (as adjusted in accordance with Section 12).

4.   Participants. Participants will consist of such officers and key employees of the Company or any designated subsidiary as the Administrator in its sole discretion shall determine. Designation of a participant in any year shall not require the Administrator to designate such person to receive a benefit in any other year or to receive the same type or amount of benefit as granted to the participant in any other year or as granted to any other participant in any year. The Administrator shall consider such factors as it deems pertinent in selecting participants and in determining the type and amount of their respective benefits.

5.   Types of Benefits . The following benefits may be granted under the Plan: (a) stock appreciation rights (“SARs”); (b) restricted stock (“Restricted Stock”); (c) performance awards (“Performance Awards”); (d) incentive stock options (“ISOs”); (e) nonqualified stock options (“NQSOs”); and (f) Stock Units, all as described below.

6.   Stock Appreciation Rights . A SAR is the right to receive all or a portion of the difference between the fair market value of a share of Common Stock at the time of exercise of the SAR and the exercise price of the SAR established by the Administrator, subject to such terms and conditions set forth in a SAR agreement as may be established by the Administrator in its sole discretion. At the discretion of the Administrator, SARs may be exercised (a) in lieu of exercise of an option, (b) in conjunction with the exercise of an option, (c) upon lapse of an option, (d) independent of an option or (e) each of the above in connection with a previously awarded option under the Plan. If the option referred to in (a), (b) or (c) above qualified as an ISO pursuant to Section 422 of the Internal Revenue Code of 1986 (“Code”), the related SAR shall comply with the applicable provisions of the Code and the regulations issued thereunder. At the time of grant, the Administrator may establish, in its sole discretion, a maximum amount per share which will be payable upon exercise of a SAR, and may impose conditions on exercise of a SAR. At the discretion of the Administrator, payment for SARs may be made in cash or shares of Common Stock of the Company, or in a combination thereof. SARs will be exercisable not later than ten years after the date they are granted and will expire in accordance with the terms established by the Administrator.

7.   Restricted Stock. Restricted Stock is Common Stock of the Company issued or transferred under the Plan (other than upon exercise of stock options or as Performance Awards) at any purchase price less than the fair market value thereof on the date of issuance or transfer, or as a bonus, subject to such terms and conditions set forth in a Restricted Stock agreement as may be established by the Administrator in its sole discretion. In the case of any Restricted Stock:

C-2







(a)   The purchase price, if any, will be determined by the Administrator.

(b)   The period of restriction shall be established by the Administrator for any grants of Restricted Stock;

(c)   Restricted Stock may be subject to (i) restrictions on the sale or other disposition thereof; (ii) rights of the Company to reacquire such Restricted Stock at the purchase price, if any, originally paid therefor upon termination of the employee’s employment within specified periods; (iii) representation by the employee that he or she intends to acquire Restricted Stock for investment and not for resale; and (iv) such other restrictions, conditions and terms as the Administrator deems appropriate.

(d)   The participant shall be entitled to all dividends paid with respect to Restricted Stock during the period of restriction and shall not be required to return any such dividends to the Company in the event of the forfeiture of the Restricted Stock.

(e)   The participant shall be entitled to vote the Restricted Stock during the period of restriction.

(f)   The Administrator shall determine whether Restricted Stock is to be delivered to the participant with an appropriate legend imprinted on the certificate or if the shares are to be issued in the name of a nominee or deposited in escrow pending removal of the restrictions.

Notwithstanding the above, the maximum number of shares of Restricted Stock that may be awarded in any calendar year to any individual shall not exceed 50,000 shares (as adjusted in accordance with Section 12).

8.   Performance Awards . Performance Awards are Common Stock of the Company, monetary units or some combination thereof, to be issued without any payment therefor, in the event that certain performance goals established by the Administrator are achieved over a period of time designated by the Administrator, but not in any event more than five years. The goals established by the Administrator may include return on average total capital employed, earnings per share, increases in share price or such other goals as may be established by the Administrator. In the event the minimum corporate goal is not achieved at the conclusion of the period, no payment shall be made to the participant. Actual payment of the award earned shall be in cash or in Common Stock of the Company or in a combination of both, as the Administrator in its sole discretion determines. If Common Stock of the Company is used, the participant shall not have the right to vote and receive dividends until the goals are achieved and the actual shares are issued.

9.   Incentive Stock Options. ISOs are stock options to purchase shares of Common Stock at not less than 100% of the fair market value of the shares on the date the option is granted, subject to such terms and conditions set forth in an option agreement as may be established by the Administrator in its sole discretion that conform to the requirements of Section 422 of the Code. Such purchase price may be paid (a) by check or (b), in the discretion of the Administrator, by the delivery of shares of Common Stock owned by the participant for at least six months, or (c), in the discretion of the Administrator, by a combination of any of the foregoing, in the manner provided in the option agreement. The aggregate fair market value (determined as of the time an option is granted) of the stock with respect to which ISOs are exercisable for the first time by an optionee during any calendar year (under all option plans of the Company and its subsidiaries) shall not exceed $100,000.

C-3





 
10.   Nonqualified Stock Options . NQSOs are nonqualified stock options to purchase shares of Common Stock at purchase prices established by the Administrator on the date the options are granted, subject to such terms and conditions set forth in an option agreement as may be established by the Administrator in its sole discretion; provided, however , in no event shall the purchase price per share be less than 100% of the fair market value of the shares on the date the option is granted. The purchase price may be paid (a) by check or (b), in the discretion of the Administrator, by the delivery of shares of Common Stock owned by the participant for at least six months, or (c), in the discretion of the Administrator, by a combination of any of the foregoing, in the manner provided in the option agreement.

11.   Stock Units. A Stock Unit represents the right to receive a share of Common Stock from the Company at a designated time in the future, subject to such terms and conditions set forth in a Stock Unit agreement as may be established by the Administrator in its sole discretion. The participant generally does not have the rights of a shareholder until receipt of the Common Stock. The Administrator may in its discretion provide for payments in cash, or adjustment in the number of Stock Units, equivalent to the dividends the participant would have received if the participant had been the owner of shares of Common Stock instead of the Stock Units.

12.   Adjustment Provisions .

(a)   If the Company shall at any time change the number of issued shares of Common Stock without new consideration to the Company (such as by stock dividends or stock splits), the total number of shares reserved for issuance under this Plan and the number of shares covered by each outstanding benefit shall be adjusted so that the aggregate consideration payable to the Company, if any, and the value of each such benefit shall not be changed. Benefits may also contain provisions for their continuation or for other equitable adjustments after changes in the Common Stock resulting from reorganization, sale, merger, consolidation, issuance of stock rights or warrants, or similar occurrence.

(b)   Notwithstanding any other provision of this Plan, and without affecting the number of shares reserved or available hereunder, the Board of Directors may authorize the issuance or assumption of benefits in connection with any merger, consolidation, acquisition of property or stock, or reorganization upon such terms and conditions as it may deem appropriate.

13.   Nontransferability. Each benefit granted under the Plan to an employee shall not be transferable otherwise than by will or the laws of descent and distribution; provided, however, NQSOs granted under the Plan may be transferred, without consideration, to a Permitted Transferee (as defined below). Benefits granted under the Plan shall be exercisable, during the participant’s lifetime, only by the participant or a Permitted Transferee. In the event of the death of a participant, exercise or payment shall be made only:

(a)   By or to the Permitted Transferee, executor or administrator of the estate of the deceased participant or the person or persons to whom the deceased participant’s rights under the benefit shall pass by will or the laws of descent and distribution; and

(b)   To the extent that the deceased participant or the Permitted Transferee, as the case may be, was entitled thereto at the date of his death.

For purposes of this Section, “Permitted Transferee” shall include (i) one or more members of the participant’s family, (ii) one or more trusts for the benefit of the participant and/or one or more members

C-4






of the participant’s family, or (iii) one or more partnerships (general or limited), corporations, limited liability companies or other entities in which the aggregate interests of the participant and members of the participant’s family exceed 80% of all interests. For this purpose, the participant’s family shall include only the participant’s spouse, children and grandchildren.

14.   Taxes . The Company shall be entitled to withhold the amount of any tax attributable to any amounts payable or shares deliverable under the Plan after giving the person entitled to receive such payment or delivery notice as far in advance as practicable, and the Company may defer making payment or delivery as to any benefit if any such tax is payable until indemnified to its satisfaction. The person entitled to any such delivery may, by notice to the Company at the time the requirement for such delivery is first established, elect to have such withholding satisfied by a reduction of the number of shares otherwise so deliverable, such reduction to be calculated based on a closing market price on the date of such notice.

15.   Tenure . A participant’s right, if any, to continue to serve the Company and its subsidiaries as an officer, employee, or otherwise, shall not be enlarged or otherwise affected by his or her designation as a participant under the Plan.

16.   Duration, Interpretation, Amendment and Termination . No benefit shall be granted more than ten years after the date of adoption of this Plan; provided, however, that the terms and conditions applicable to any benefit granted within such period may thereafter be amended or modified by mutual agreement between the Company and the participant or such other person as may then have an interest therein. Also, by mutual agreement between the Company and a participant hereunder, stock options or other benefits may be granted to such participant in substitution and exchange for, and in cancellation of, any benefits previously granted such participant under this Plan. To the extent that any stock options or other benefits which may be granted within the terms of the Plan would qualify under present or future laws for tax treatment that is beneficial to a recipient, then any such beneficial treatment shall be considered within the intent, purpose and operational purview of the Plan and the discretion of the Administrator, and to the extent that any such stock options or other benefits would so qualify within the terms of the Plan, the Administrator shall have full and complete authority to grant stock options or other benefits that so qualify (including the authority to grant, simultaneously or otherwise, stock options or other benefits which do not so qualify) and to prescribe the terms and conditions (which need not be identical as among recipients) in respect to the grant or exercise of any such stock option or other benefits under the Plan.

The Board of Directors may amend the Plan from time to time or terminate the Plan at any time. However, no action authorized by this paragraph shall reduce the amount of any existing benefit or change the terms and conditions thereof without the participant’s consent. No amendment of the Plan shall, without approval of the stockholders of the Company, (a) increase the total number of shares which may be issued under the Plan or increase the amount or type of benefits that may be granted under the Plan; or (b) modify the requirements as to eligibility for benefits under the Plan.

17.   Effective Date. The Plan will be effective immediately following approval by the stockholders of the Company at the 2006 Annual Meeting of Stockholders.

The Compensation Committee will specifically define such terms at the time it establishes the performance goals. Such performance goals shall be sufficiently detailed and objective so that a third party having knowledge of the relevant performance results could calculate the amount to be paid to the Participant pursuant to such Performance Award formula.

(b) The Compensation Committee shall also establish the Performance Award payable to a Participant if the performance goals are achieved. The payment of any Award shall be subject to achievement of the performance goals.

(e) The maximum aggregate amount of compensation that may be paid to a Participant in any fiscal year of the Company pursuant to one or more Performance Awards under this Plan shall not exceed the Maximum Amount for such fiscal year. If the Maximum Amount (including carryforwards under this sentence) for a fiscal year exceeds the amount paid to a Participant in that year, such excess shall be carried forward and added to the Maximum Amount for the succeeding fiscal year.

  (b) The Plan shall be governed by the laws of the State of Missouri and applicable federal law.

9.   Modification Or Termination Of Plan . The Board may modify or terminate the Plan at any time, effective at such date as the Board may determine.

10.   Stockholder Approval . This Plan shall be subject to approval by the affirmative vote of a majority of the shares of Common Stock cast in a separate vote of the stockholders of the Company at the 2006 Annual Meeting of Stockholders, and such stockholder approval shall be a condition to the right of a Participant to receive any Award hereunder.
