            giving no less than three (3) months notice in writing to STANTEC
            (the "Notice Period"), in which case the Executive shall be paid
            only the Base Salary actually earned by the Executive to the date of

            provided further that the Executive shall not be entitled to any

            Notice Period; and

      b)    at any time prior to the Executive's sixty-fifth birthday, STANTEC

            hereto.

      hereto.

3.4   TERMINATION ON PERMANENT INCAPACITY OF THE EXECUTIVE

      such permanent incapacity occurs.

3.5   TERMINATION BY EXECUTIVE BY REASON OF CHANGE OF CONTROL OF STANTEC INC.

            if any one of the following occur after the date hereof:

            (i)   a third person, including a person, firm, syndicate, group or
                  corporation, becomes the beneficial owner, directly or
                  indirectly, of shares of Stantec Inc. carrying more than 50%
                  of the total number of votes that may be cast for the election
                  of directors of Stantec Inc.; or

            (ii)  a third person, including a person, firm, syndicate, group or
                  corporation, becomes the beneficial owner, directly or
                  indirectly, of shares of Stantec Inc. carrying more than 30%
                  of the total number of votes that may be cast for the election
                  of directors of Stantec Inc. and when nominees of the said 30%
                  holder are elected as a majority of the Stantec Inc. Board of
                  Directors.

                                                                     Page 3 of 9
<PAGE>

      b)    If during the term of this Agreement, there occurs a change of
            control of Stantec Inc., the Executive shall, in his sole discretion
            and at any time within the six (6) month period immediately
            following the date of such change of control, be entitled to
            terminate this Agreement. Upon the termination of this Agreement
            pursuant to this paragraph, STANTEC shall cause to be paid to the
            Executive in full and final satisfaction of all of its obligations
            to the Executive the amount of $100,000, the Base Salary actually
            earned by the Executive to the date of termination and a bonus in
            accordance with Schedule "A" attached hereto.

3.6   TERMINATION AT AGE SIXTY FIVE

      This Agreement shall terminate on the Executive's sixty-fifth birthday
      without further notice or compensation other than the Base Salary actually
      earned by the Executive to the date of termination.

4.    THE EXECUTIVE'S OBLIGATIONS

4.1   CONFIDENTIALITY

      The Executive shall treat all information obtained during the Executive's
      employment with STANTEC as confidential (the "Confidential Information").
      The Executive shall not use the Confidential Information in any manner
      detrimental to the interests of STANTEC nor shall the Executive disclose
      the Confidential Information to any party except in the interests of
      STANTEC.

4.2   NON-COMPETITION

      The Executive acknowledges and agrees that in the performance of his
      duties he will necessarily acquire detailed knowledge of the business and
      affairs of STANTEC and that STANTEC will suffer harm in the event that
      such confidential information is disclosed to its competitors or in the
      event that the Executive uses such confidential information for any
      purpose other than the performance of his duties as an employee of
      STANTEC. Therefore, the Executive covenants and agrees that for a period
      of two (2) years following termination of the Executive's employment with
      STANTEC under this Agreement, he will not directly or indirectly as an
      owner, employee, servant, consultant, contractor, agent or otherwise,
      engage in business or otherwise provide services in competition with
      STANTEC in the Province of Alberta.

      The foregoing restrictions also apply to other geographic areas, including
      international areas, for work in the following categories:

      a)    work being done or started by STANTEC or any of its affiliated or
            subsidiary companies;

      b)    work for which a previous report or proposal has been prepared or
            submitted by STANTEC or any of its affiliated or subsidiary
            companies within two (2) years prior to the termination of this
            Agreement; and

      c)    work for which promotional efforts by STANTEC or any of its
            affiliated or subsidiary companies, or any one in their employ, had
            occurred during the period of two (2) years prior to the termination
            of this Agreement.

      The Executive has read and understood the provisions of this Section 4.2,
      agrees with the restrictions set forth herein and agrees that the time
      period and geographic location

                                                                     Page 4 of 9
<PAGE>

      restrictions are fair, reasonable and legitimately necessary for the
      protection of STANTEC's interests. In the event a Court of competent
      jurisdiction declares the time period or geographic location restrictions
      to be unreasonable, the Executive and STANTEC covenant and agree that the
      time period restriction shall be reduced to one (1) year and the
      geographic location restriction be limited to the City of Edmonton. In the
      further event that a court of competent jurisdiction declares the reduced
      time period or geographic location restrictions to be unreasonable, the
      Executive and STANTEC covenant and agree that the time period restriction
      shall be further reduced to six (6) months and the geographic location
      restriction be limited to the City of Edmonton.

4.3   CHANGE OF GEOGRAPHIC AREA

      The Executive covenants and agrees that in the event the Executive is at
      some later date responsible for a different geographic area, Section 4.2
      remains in full force and effect and shall be deemed to apply to the new
      area in the same manner and to the same extent as if the new geographic
      area had been identified as the geographic area in Section 4.2 hereof.

4.4   NON-SOLICITATION OF EMPLOYEES AND CLIENTS

      The Executive acknowledges and agrees that during the continuance of his
      employment and for a period of two (2) years thereafter, he will not, for
      his own private advantage, or for the advantage of any third party:

      a)    hire any employee of STANTEC or its affiliates or subsidiaries, or
            induce or attempt to induce any employee of STANTEC or its
            affiliates or subsidiaries to leave their employment with STANTEC;
            nor

      b)    contact, solicit, sell, serve, divert or receive any business to or
            from any of the clients of STANTEC or its affiliates or
            subsidiaries.

4.5   EXCEPTION FOR TERMINATION WITHOUT CAUSE

      In the event of the termination of this Agreement by STANTEC without
      cause, the provisions of Sections 4.2 and 4.4 shall be limited to one (1)
      year (or such lesser period if applicable, as set out in Section 4.2
      above).

4.6   STANTEC INFORMATION

      All notes, records, working papers, files, research material, literature,
      drawings, computer software and other proprietary information ("STANTEC's
      Information") accumulated or developed by the Executive in connection with
      his assignments at STANTEC and any technological concepts or devices
      resulting therefrom, whether patentable or otherwise, are considered the
      property of STANTEC and the Executive may not copy, secure, transmit,
      keep, store, gain from, sell or use STANTEC's Information or property for
      any purposes other than in undertaking assignments at STANTEC. To the
      extent necessary, the Executive covenants and agrees to execute and
      deliver to STANTEC, or such of its subsidiaries or affiliates as STANTEC
      directs, such documents or instruments as may be necessary to assign any
      of the rights or interests described in this section that are developed by
      the Executive.

                                                                     Page 5 of 9
