Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensation Arrangement of Certain Officers.

On September 5, 2008, the Senior Vice President and Chief Operating Officer of Insituform Technologies, Inc. (the “Company”), Thomas E. Vossman, notified the Company he will resign effective September 5, 2008 due to personal reasons.  Mr. Vossman will transition to the status of consultant for the Company, where, among other things, he will assist Joe Burgess, the Company’s President and Chief Executive Officer, in analyzing the overall organizational and management structure for the Company’s North American operations.

The Company has entered into an agreement (the “Separation Agreement”) with Mr. Vossman that provides for certain separation benefits, including, among other things, an aggregate cash payment of $265,000 payable in (1) a lump sum payment of $162,500 to be paid within five business days of the date of the Separation Agreement, and (2) additional payments in the aggregate amount of $102,500, payable in equal semi-monthly installments, beginning on September 16, 2008 (together, the “Severance Payment”).

The Severance Payment will be paid by the Company in consideration of certain representations, warranties, covenants and agreements made by Mr. Vossman, including, but not limited to, covenants of confidentiality, non-solicitation and non-competition.

The Separation Agreement also provides Mr. Vossman with outplacement assistance for a period of six months at an aggregate expense to the Company of not more than $10,000.00.  The Company has agreed to provide Mr. Vossman with continuation of medical and dental coverage under the Company’s medical and dental plans until the earlier of August 31, 2009 or the date Mr. Vossman is entitled to receive health benefits from a new employer, at a cost that would be paid by an employee receiving comparable benefits.  If Mr. Vossman wishes to continue health benefits after August 31, 2009 for the remainder of the COBRA period, he may do so at the full COBRA cost.

To the extent Mr. Vossman has outstanding stock options, restricted stock and restricted stock units of the Company, Mr. Vossman’s resignation is deemed to be a termination by the Company without cause for purposes of the award agreements.

In addition, Mr. Vossman will enter into a consulting agreement (“Consulting Agreement”) with the Company commencing as of the effective date of his resignation and continuing through December 31, 2008.  Mr. Vossman will be paid $30,000 per month under the consulting arrangement; provided, however, if the consulting services require in excess of 125 hours of Mr. Vossman’s time in any calendar month, the Company will pay Mr. Vossman at the rate of $240 per hour for the excess time.

The foregoing descriptions of the Separation Agreement and the Consulting Agreement are qualified in their entirety by reference to the Separation Agreement and Consulting Agreement, copies of which are attached as Exhibit 10.1 and 10.2 hereto and are incorporated herein by reference.
