	 	(1)	The Employee will receive a termination payment (the “Change of Control Payment”) equal to the greater of: (A) eighteen (18) months’
compensation calculated in accordance with subparagraph (e)(ii)(3) below; or, (B) the minimum notice and minimum severance (if any) to which the Employee is then entitled in accordance with the minimum requirements of Ontario’s Employment

	 	(2)	Subject to the provisions of subparagraph 7(h), the Change of Control Payment will be paid by the Employer in a series of equal installments according to the
Employer’s regular payroll schedule, over a period of eighteen (18) months commencing with the first payroll after the Designated Termination Date. Notwithstanding the foregoing, subject always to the provisions of subparagraph 7(h), the
Employer may in its absolute discretion elect to pay all or any part of the Change of Control Payment in one or more lump sum amounts, in which case the amount of any further monthly installments will be adjusted accordingly.

salary, plus (B) monthly bonus equal to 1/36th of the total of all bonuses paid to the Employee during the three (3) most recently completed fiscal years. If the

	 	 
Employee has completed less than three (3) years of service with the Employer, then monthly bonus will instead be calculated based on the total bonus paid to the Employee prior to the
termination date, divided by the number of months of service completed as of the termination date.

which cannot be so continued. 

  

	 	ii.	“Good Reason” shall mean any of the following, unless the Employee gives his express written consent thereto: 

  

	 	(i)	a material adverse change in the Employee’s status or position as an officer or employee of the Company, as in effect immediately prior to a Change of Control.
Such material adverse change shall include without limitation any material adverse change in status or position as a result of a material diminution in the Employee’s duties or responsibilities or the assignment to the Employee of any duties or
responsibilities which are materially inconsistent with such status or position; 

  

	 	(ii)	a material reduction by the Company in the Employee’s annual base salary as in effect immediately prior to a Change of Control; 

  

	 	(iii)	a material failure by the Company to continue in effect any employee benefit or bonus program in which the Employee is participating at the time of a Change of Control
other than as a result of the normal expiration of any such program in accordance with its terms as in effect at the time of a Change of Control or replacement of such program with a comparable program, or the taking of any action, or the failure to
act, by the Company which would materially and adversely affect the Employee’s continued participation in any such employee benefit or bonus program on at least as favourable a basis to the Employee as on the date of a Change of Control;

  

	 	(v)	the Company requiring the Employee to be based anywhere other than where the Employee is based at the time of a Change of Control, except for required travel on the
Company’s business to an extent substantially consistent with the Employee’s business travel obligations in the ordinary course of business immediately prior to the Change of Control; 

 Notwithstanding the foregoing, the Employee must give notice to the Company within 60 days following the Employee’s knowledge of an
event constituting Good Reason describing the alleged failure or action by the Company and advising of the Employee’s intention to terminate the Employee’s employment for Good Reason. The Company shall have 14 business days to correct such
failure or action following the delivery by the Employee of such written notice. If the Employee fails to provide such notice within 60 days, such event shall not constitute Good Reason under this Agreement. 
  

	 	iii.	The Change of Control Payment includes the Employee’s entitlements under applicable employment standards legislation and regulations, the common law or otherwise
and shall be in full settlement of all severance payments to the Employee under this agreement or any other employment, termination or severance agreement between the Company and the Employee or any severance plan or policy of the Company. The
Employee shall sign and deliver a release acceptable to the Company prior to receiving the Change of Control Payment.
