     4.   Stock Options. Effective upon your assumption of the
          position of President and chief executive officer of ITI,
          and appointment to the Board of Directors (the "Effective

          to ITI's 1992 Director Stock Option Plan (the "Plan")
          will become effective:

               the purchase of 100,000 shares of the class A
               common stock, $.01 par value (the "Common Stock"),
               of ITI, such options to become exercisable with
               respect to 10% of such shares on the first
               anniversary of the Effective Date, with respect to
               an additional 20% of such shares on the second
               anniversary of the Effective Date, with respect to
               an additional 30% of such shares on the third

               the Effective Date as determined under the terms of
               the Plan.

               for the purchase of 50,000 shares of Common Stock,
               such options to become exercisable with respect to
               10% of such shares on the second anniversary of the
               Effective Date, with respect to an additional 20%
               of such shares on the third anniversary of the
               Effective Date, with respect to an additional 30%
               of such shares on the fourth anniversary of the
               Effective Date, and with respect to the remaining
               40% of such shares on the fifth anniversary of the
               Effective Date, such options to expire on the sixth
               anniversary of the Effective Date. The exercise
               price per share for the Additional Options shall be
               $15.00.

          The Initial Options and the Additional Options shall be
          in addition to the options to acquire shares of Common
          Stock you presently hold, and: (x) to the maximum extent
          permitted under the limitations contained in the Internal
          Revenue Code (the "Code") and considering your
          outstanding options, the Initial Options shall be
          "incentive stock options", the remainder of which shall
          be non-qualified stock options; and (y) after giving
          effect to the foregoing clause (x), to the maximum extent
          permitted under the limitations contained in the Code the
          Additional Options shall be "incentive stock options",
          the remainder of which shall be non-qualified stock
          options.  The foregoing exercise schedules anticipate
          your continued employment with ITI as set forth in the
          Plan, such options otherwise to conform to the provisions
          of the Plan and the form of option agreements thereunder
          heretofore adopted by the Director Stock Option Committee
          of the Board of Directors. 

          In addition, the Initial Options and the Additional
          Options will provide that they become immediately
          exercisable upon the occurrence of a change in control of
          ITI of a nature that would be required to be reported in
          response to Item 6(e) of Schedule 14A of Regulation 14A
          promulgated under the Securities Exchange Act of 1934 (or
          in response to any similar item on any similar schedule
          or form), whereby any "person" (as defined under Section
          13(d) of said Act) who is not on the date hereof the
          "beneficial owner" (as defined in Rule 13d-3 under said
          Act) of in excess of 5% of the outstanding Common Stock


          becomes the beneficial owner of in excess of 50% of the
          outstanding Common Stock.

     5.   Additional Benefits. 

               (a) You shall be provided with a car allowance in
          the amount currently paid to you, subject to adjustment
          in accordance with ITI's policy.

               (b)  You will be reimbursed for country club
          membership fees for one club in the Memphis area.

               (c)  You will participate in the ITI 401(k) Profit-
          Sharing Plan, and medical insurance and life insurance
          programs, including ITI's supplemental executive life
          insurance and long-term disability program.

               (d)  You will receive holidays and vacations in
          accordance with ITI's policy, with the understanding that
          the position of President currently provides four weeks
          of vacation.

     6.   Severance. In the event you are terminated for reasons
          other than "cause", you would be entitled to severance
          equal to twelve months' Base Salary, which would be paid
          over that period. "Cause" shall be defined as a
          substantial dereliction of duty after written notice
          thereof, conviction of a felony or inability to report
          for work for a period of four months or greater.

     7.   Secrecy; Non-Competition. You hereby acknowledge and
          agree that you have previously entered into a Non-
          Disclosure and Non-Competition Agreement dated January
          27, 1994 with ITI, the terms of which are hereby
          incorporated by this reference herein and deemed to be a
          part of this letter. Without limiting the provisions
          thereof, you hereby agree that, during your employment or
          other relationship with ITI or any Affiliate thereof (as
          hereinafter defined), and for a period of one year
          subsequent to the termination of your employment or other
          relationship with ITI or any Affiliate thereof, you will
          not, directly or indirectly, engage in the business of
          rehabilitating, lining, relining, coating, constructing
          or reconstructing pipelines, sewers, conduits or
          passageways (the "Services") anywhere in the world, or
          otherwise engage in Prohibited Competition (as
          hereinafter defined). You agree and acknowledge that it
          is contemplated that ITI will continue to seek and obtain
          work in the United States and internationally and
          acknowledge that ITI's business presently involves
          operations in the United States and internationally.
          Accordingly, you agree that the foregoing geographic


          scope is reasonable in light of current and presently
          anticipated operations of ITI.

          For purposes of this Section 7, "Prohibited Competition"
          shall include, but not be limited to, acting as
          consultant, advisor, independent contractor, officer,
          manager, employee, principal, agent, director or trustee
          of any corporation, partnership, association or agent or
          agency, or directly or indirectly owning more than one
          percent of the outstanding capital stock of any
          corporation, or being a member or employee of any
          partnership or any owner or employee of any other
          business, any of which is engaged in providing any of the
          Services. "Prohibited Competition" also shall include (in
          addition to the foregoing):

                    (i)   Accepting employment with a customer of
               ITI or of its Affiliates with the intent or purpose
               of transferring defined business performed by ITI
               or its Affiliates to a department, division or
               affiliate of the customer;

                    (ii)  Requesting or advising any of the
               customers, suppliers, or other business contacts of
               ITI or its Affiliates to withdraw, curtail or
               cancel their business with ITI or its Affiliates;
               or

                    (iii) Causing or inducing, or attempting to
               cause or induce, either directly or indirectly, any
               employees, sales representatives, consultants or
               other personnel of ITI or its Affiliates to
               terminate their relationships  or employment or
               breach their agreements with ITI or its Affiliates,
               whether for the purpose of accepting employment
               with you or any other person, firm, association or
               corporation with which you are associated, or
               otherwise.

          As used herein, "Affiliate" shall mean any entity
          directly or indirectly controlled by ITI.

          You recognize that the breach of any of your obligations
          under this Section 7 may give rise to irreparable injury
          to ITI or its Affiliates inadequately compensable in
          damages and that, accordingly, ITI or any of its
          Affiliates may seek injunctive relief against the breach
          or threatened breach of the within undertaking, in
          addition to other remedies at law or in equity which may
          be available. You acknowledge that compliance with your
          obligations under this Section 7 will not impair your
          ability to earn a livelihood.


          If any restriction set forth in this Section 7 is found
          by any court of competent jurisdiction to be
          unenforceable because it extends for too long a period of
          time or over too great range of activities or in too
          broad a geographic area, it shall be interpreted and
          amended automatically to extend only over the maximum
          period of time, range of activities or geographic area as
          to which it may be enforceable to protect the interests
          of ITI and its Affiliates.

                    *           *           *

     I look forward to your assuming the position of President and
chief executive officer of ITI and continuing as a part of this
exciting opportunity in your new capacity. If the above accurately
reflects our understandings, please sign the copy of his letter
where indicated and send such copy back to me acknowledging your
acceptance of the offer.
     
                                   Very truly yours,

                                   INSITUFORM TECHNOLOGIES, INC.
