3.       SALARY AND COMPENSATION

         The Corporation agrees to pay Childers for all of the services rendered
         by him hereunder and Childers agrees to accept as compensation therefor
         the following (all of which amounts are expressed in United States
         dollars):

         a.       While Childers holds the position of Chairman and Chief
                  Executive Officer a basic salary payable monthly, subject to
                  all required and proper deductions, as follows:

                  i.       for the period January 1, 1997 to December 31, 1997
                           the sum of one million, one hundred thousand

                           dollars.

         b.       In addition to the amounts payable to Childers under this
                  Agreement or under any other benefit plan or program, while
                  Childers holds the position of Chairman and Chief Executive
                  Officer, an amount equal to any amount paid to Childers
                  pursuant to the Corporation's Short Term Incentive Plan.

         c.       After Childers ceases to hold the position of Chief Executive
                  Officer, he shall be paid the sum of three hundred thousand
                  ($300,000) dollars less any amount paid to Childers for his
                  role as Chairman and Director as an annual retainer payable
                  monthly subject to all required and proper deductions.


4.       DUTIES OF EMPLOYEE

         It shall be Childers' responsibility to faithfully and competently
         perform all of the services ordinarily required of a Chief Executive
         Officer of a major corporation such as that of the Corporation. It
         shall be Childers' responsibility to direct all aspects of the
         operation of the Corporation. It shall be Childers' responsibility as
         Chairman to preside at Board Meetings and carry out those functions as
         are authorized by the bylaws of the Corporation. Upon assuming the
         responsibility as a special advisor to the Corporation it shall be
         Childers' responsibility to assist in customer and public relations,

6.       INCOME TAX COMPENSATION

         The Corporation acknowledges that Childers may be subject to a higher
         rate of income taxation in Canada on income earned by Childers while
         resident in Canada than Childers would be liable to pay if he resided
         in the United States and earned an equivalent amount of income there.
         The Corporation further acknowledges that the parties intend that
         Childers' after tax position pursuant to the terms of this Agreement
         based on the income earned by Childers shall be no different than if he
         resided in the United States and earned an equivalent amount of income
         in that country. Accordingly, the parties agree that a firm of
         Chartered Accountants, mutually agreed upon by the parties, shall, on
         an annual basis, complete the necessary calculations to determine the
         income tax payable by Childers in Canada and in the United States as if
         he had continued to reside in the State of Illinois. In the event that
         the first amount (i.e., federal and provincial tax payable in Canada)
         exceeds the second amount (i.e., projected federal and state tax
         payable in the United States) the Corporation shall pay Childers an
         amount, to be determined by such Chartered Accountants, such that
         Childers' aggregate income on an after-tax basis would be equal to that
         which he would have earned had he been a resident of the State of
         Illinois during the entire taxable year.


7.       CORPORATION'S DISABILITY, RETIREMENT AND PENSION PLAN

         a)       Childers shall be entitled to participate in the benefits plan
                  which are currently available to senior executives of the
                  Corporation. Upon termination of employment the Corporation
                  agrees to provide a comprehensive medical, vision, and dental
                  insurance plan for Childers equivalent to the medical, vision,
                  and dental plan currently in existence (a description of which
                  plan is set forth in Schedule I attached hereto) which plan
                  shall remain in effect for the lifetime of Childers. The
                  commitment to provide medical, vision, and dental insurance
                  shall survive this Agreement.

         b)       Both parties hereto acknowledge and agree that, effective July
                  1, 1999 and not withstanding Childers continued provision of
                  services to the Corporation in his role of Chairman of the
                  Board and special advisor, Childers shall be deemed to have
                  retired from employment with the Corporation.


8.       EXECUTIVE BONUS PROGRAM

         For so long as he serves as Chief Executive Officer, Childers shall be
         entitled to receive in addition to compensation provided for in this
         Agreement, additional compensation as is provided for in Schedule II
         attached hereto and forming part of this Agreement.


9.       CORPORATE AIRCRAFT

         The Corporation, in recognition of the importance to it of Childers'
         security, safety and efficient use of time, authorizes and expects
         Childers to use the principal corporate aircraft for all business and
         personal travel. The Corporation hereby agrees to indemnify Childers
         for any and all income taxes payable by him resulting from travel on
         such aircraft by him or members of his family who may accompany him.
         Furthermore, the Corporation hereby agrees to compensate Childers for
         any

                                                                          Page 4


         additional income taxes he may incur as a result of any indemnity
         payments for income taxes incurred from his use of such aircraft or for
         any compensating payments for additional taxes incurred on a
         compensating payment.


10.      DEATH OR DISABILITY OF EMPLOYEE

         If, prior to July 1, 1999, Childers becomes physically or mentally
         incapable of performing the services required of him and such
         incapacity is or may reasonably be expected to exist for more than four
         months, or Childers dies, then Childers or his estate shall be entitled
         to receive and be paid compensation up to and including June 30, 1999
         as if he had not been disabled or died, less any amounts of disability
         benefits that are available to Childers or his estate that have been
         provided by the Corporation.


11.      TERMINATION

         In the event that the Corporation shall terminate this Agreement for
         any reason or under circumstances other than for cause, the Corporation
         shall pay to Childers at the time of such termination all sums,
         including salaries, bonuses and income tax compensation, that would
         have been paid to Childers pursuant to this Agreement had this
         Agreement remained in full force and effect from the date of
         termination to the end of the term of this Agreement.


12.      VOLUNTARY RESIGNATION

         In the event that Childers shall voluntarily resign during the term of
         this Agreement or any renewal hereof, the Corporation shall pay to
         Childers at the time of such resignation the total of all salaries and
         bonuses earned by Childers to the date of such termination plus the
         income tax compensation with respect to those salaries and bonuses.


13.      TERMINATION FOR CAUSE

         The Corporation shall be entitled to terminate the services of Childers
         in the event of the infidelity of Childers to the Corporation. For the
         purposes of this provision, "infidelity" shall be defined as including
         any illegal act by Childers in relation to the property of the
         Corporation whereby Childers achieves a personal gain therefrom. In the
         event that the Corporation shall terminate the services of Childers
         pursuant to this provision, the Corporation shall pay to Childers at
         the time of such termination all salaries and bonuses earned by
         Childers to the date of such termination plus the income tax
         compensation with respect to those salaries and bonuses.

14.      BENEFITS PAYABLE UPON TERMINATION

         Upon termination of this Agreement for any reason including the expiry
         of the term, the Corporation agrees that it shall reimburse Childers
         for all reasonable moving expenses incurred by Childers. The
         Corporation agrees that Childers shall be entitled to participate in
         the Corporation's "home purchase plan" that is available to senior
         employees that are transferred.


15.      MERGER, TAKE-OVER OR SALE OF THE CORPORATION

         The Corporation agrees that in the event the undertaking of the
         Corporation is sold, dissolved, merged or amalgamated, the Corporation
         shall ensure that Childers shall retain his positions of the successor
