below:

 

1. Term. The term of the Agreement is extended until December 31, 2006.

 

2. Cash Compensation. The Executive shall be entitled to be paid base 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 by the
Board after consultation with the Executive. The Executive shall be considered
for a bonus based upon performance to December 31, 2006 which is payable in
2007. Notwithstanding the above, in the event there is a Change of Control
during the term, the Executive shall be guaranteed a minimum bonus of $750,000
(the “Guaranteed Bonus”) for performance in 2006.

 

3. Incentive Compensation. The Executive shall be granted as soon as
practicable, in accordance with the terms of the IMAX Stock Option Plan (the

common shares upon such Change of Control and the closing price of the Company’s
shares on March 10, 2006. Nothing herein should be viewed as precedent with
respect to the type of options the Executive is normally granted under his
employment agreement (i.e. options that vest one year after grant date).

 

4. Severance. If the Executive’s employment is terminated by the Company without
Cause, then the Company shall pay to the Executive (in addition to all amounts
owed to the Executive that are due to be paid to and including the date upon
which the Executive’s employment is terminated) a lump sum equal to (a) twelve
(12) months of Executive’s base salary plus (b) either (i) the Executive’s
target bonus (i.e. one times salary) or, (ii) in the event there has been a
Change of Control during the term, the Guaranteed Bonus.

 

5. SERP Plan. The Co-CEO SERP Benefit Plan shall be amended as provided in
Exhibit 1.

 

6. The entering into this agreement shall not prejudice any rights or waive any
obligations under any other agreement between the Executive and the Company.
