                          AMENDED EMPLOYMENT AGREEMENT

         This agreement amends the employment agreement (the "Agreement")

         salary at the rate of $500,000 per year, plus a bonus of up to two
         times salary. Such bonus shall be at the discretion of the Board of
         Directors and shall be based upon the success of the Company in
         achieving the goals and objectives set forth in Schedule A attached
         hereto. The Executive shall be considered for a bonus payable in 2002
         based upon performance to December 31, 2001 and for a further bonus
         payable on a pro rata basis for the period from December 31, 2001 to
         June 30, 2002, unless the Agreement is further extended.

3.       RESTRICTED STOCK. The Executive shall be entitled to a grant of

5.       REGULATORY APPROVAL. The Company agrees to seek regulatory approval
         with respect to the grants of restricted stock contemplated herein. It
         is acknowledged that such regulatory approval may be contingent upon
         shareholder approval. In the event that regulatory or shareholder
         approvals cannot be obtained in respect of the issue of restricted
         stock to the Executive, the Company shall be obligated to put the
         Executive in substantially the same economic position as if the grants
         had received regulatory and shareholder approval, and the Executive
         shall be obligated to surrender options to purchase 1.3 million shares.

                                  SCHEDULE "A"

DIGITAL

1.       Develop the capability to take, on an economically viable basis, 35mm

2.       Implement the marketing and sale of an IMAX Digital Product, i.e., this
         is a smaller digital projection ----- system that maintains the IMAX
         geometry and offers better than 35mm film presentation quality.

3.       Have a clear, articulated business plan and model with respect to the
         introduction of digital cinema (conventional), which, subject to
         overall industry conditions, has a degree of validation by the studio

end of year cash, currently projected to be approximately $45-50MM, (please

repurchase of debt) or other actions endorsed by the Board.

MANAGEMENT

5.       Enhance the strength of second tier of management at IMAX through
         internal development and external hires.
