6.a. Subsection 11.b. of the Agreement shall be amended and restated in its entirety to read as follows:

“This Agreement may be immediately terminated by the Corporation by notice to the Executive if the Executive is determined to suffer from disability. The Executive shall be deemed to suffer from disability (hereinafter referred to as “Disability”) if in any year during the employment period, because of ill health, physical or mental disability, or for other causes beyond the control of the Executive, the Executive has been continuously unable or unwilling or has failed to perform the Executive’s duties for 120 consecutive days, or if, during any year of the employment period, the Executive has been unable or

The Board of Directors, acting reasonably, shall finally determine if the Executive is suffering from ill health, physical or mental disability or other causes beyond his control during the time periods as hereinbefore set forth in the event of any dispute between the Executive and the Corporation concerning the occurrence of Disability for purposes of this Section.

Notwithstanding any short term or long term corporate benefits or insurance policies relating to disability maintained by the Corporation at the relevant time, if during any period of ill health, physical or mental disability or for other causes beyond the control of the Executive, the Executive has been continuously unable or unwilling or has failed to perform the Executive’s duties less than 120 consecutive days (the “Short-Term Illness”), the Executive shall continue to receive all amounts of remuneration and benefits otherwise payable to and enjoyed by the Executive under this Agreement less any and all amounts received by and/or payable to the Executive in connection with benefits paid and/or payable as a result of such Short-Term Illness (i.e. no duplicate payments as a result of short term disability payments and the Executive’s salary payments that are due during the Short-Term Illness time period). Upon termination of this Agreement as a result of Disability, the Corporation shall pay to the Executive the severance payment provided for in Subsection 12(c) hereof less any and all amounts received by and/or payable to the Executive in connection with benefits paid and/or payable as a result of the Disability. Upon termination of this Agreement as a result of Disability, the Executive shall be entitled to continue to participate in those employee benefits referred to in Section 5 b hereof, to the extent enjoyed by the Executive prior to the occurrence of Disability, for the 15-month period immediately following the occurrence of such Disability. The term “any year of the employment period” means any period of 12 consecutive months during the employment period.

This Agreement shall terminate without notice or any payment in lieu thereof immediately upon the death of the Executive.”

“If the Executive is desirous of voluntarily terminating his employment with the Corporation, the Executive agrees to give the Corporation 3 months advance written notice of such termination, in which case the Executive shall not be entitled to any payment on account of severance under Section 12(b) hereof. The Board of Directors may waive such notice by proper resolution and in its sole discretion in which case the Executive’s employment shall be deemed to terminate immediately, provided the Executive shall still be entitled to compensation due on account of Annual Base Salary and benefits earned up to the last date of the 3 month advance written notice period given by the Executive and any Performance Bonus earned and prorated during such 3 month notice period. Provided that the Executive gives 3 months written notice as required hereunder, any unvested options which would have otherwise vested during such advance written notice period shall be permitted to vest. The Executive shall have the right to exercise any options which are vested as at the Date of Termination for the period which is 90 days following such Date of Termination (the “90 Day Period”). For purposes of this Section 11 (c), the term “Date of Termination” shall mean the actual day on which the Executive ceases to be employed plus the remainder of the 3 month notice period if and to the extent waived by the Board of Directors. Any termination properly given under Section 14.2 hereof and in accordance with the terms thereof shall not be considered a voluntary termination under this Section 11(c).”

7. Subsection 12.a. shall be amended and restated in its entirety as follows:

“Upon termination of the Executive’s employment for Just Cause, the Executive shall not be entitled to any severance or other payment other than Annual Base Salary earned by the Executive before the Date of Termination calculated pro rata up to and including the Date of Termination and all

outstanding and accrued vacation pay to the Date of Termination. Upon termination of the Executive’s employment: (i) for death; or (ii) by the voluntary termination of the employment of the Executive by the Executive pursuant to Section 11(c) hereof, the Executive shall not be entitled to any severance or other payment other than Annual Base Salary and any Performance Bonus earned by the Executive before the Date of Termination calculated pro rata up to and including the Date of Termination (which under Section 11(c) shall be as defined therein) and all outstanding and accrued vacation pay to the Date of Termination.

Notwithstanding subparagraph (ii) above, the Executive shall not be entitled to any Performance Bonus earned by the Executive before the Date of Termination unless the Executive gives the Corporation the advanced written notice required by Section 11(c) hereof.”

8. Subsection 12.b. shall be amended and restated in its entirety as follows:

“INTENTIONALLY DELETED”.

9.a. Subsection 12.c. of the Agreement shall be amended by the deletion of references to “12 month” and “12 months”, respectively, and the replacement thereof with “15 month” and “15 months”, respectively. In addition, the following paragraph shall be added to the end of Section 12.c.:

“If, at the Date of Termination, there were any memberships in any clubs, social or athletic organizations paid for by the Corporation pursuant to Schedule A hereof at the Date of Termination, the Corporation will not take any action to terminate such memberships but will not renew any such membership that expires or reimburse the Executive for any further payments therefore.”

9.b. Subsection 12.c of the Agreement shall be amended by adding a Subsection 12.c.v. as follows:

“an amount equal to 1.25 times the Executive’s target annual compensation payment for the then current fiscal year.”

10. Subsection 12.d. shall be amended and restated in its entirety as follows:

“If the Executive secures new employment or consulting work while he is entitled to severance payments under Section 12(c)(i), then from and after the date such new employment or consulting work commences, the severance payments referred to in Section 12(c)(i) to which the Executive is otherwise entitled shall be reduced immediately upon the commencement of such new employment or consulting work to a lump sum amount equal to the amount by which the Annual Base Salary exceeds the annual new salary or consulting fees, on a pro rata basis, annualized according to the unexpired term of the severance payments. The health and dental benefits referred to in Section 12(c) above shall also immediately terminate upon the commencement of such new employment or consulting work unless the Executive notifies the Corporation in writing that he is not entitled to benefits in respect of such new position or work. The Executive shall notify in writing the Corporation of all new employment and/or consulting work secured by the Executive (and the amounts received thereunder), within 14 days thereof, following the Date of Termination as long as the Executive is receiving severance payments hereunder, failing which the Executive’s continuing right to any severance payments hereunder shall cease.

Example:		Annual Base Salary		$150,000
		New Position		$100,000

Six months left of severance pay to go when new position attained

Lump sum payment to equal $50,000 x 6/12 = $25,000”

11. The last two paragraphs of Section 12 of the Agreement shall be amended and restated in their entirety as follows:

“Except as expressly stipulated in Sections 11(c) or 14 hereof and in this paragraph of Section 12, any options which have not vested as of the Date of Termination (being in the case where the Corporation gives notice, the date specified by the Corporation as the date on which the Executive’s employment will terminate) shall terminate and be of no further force and effect as of the Date of Termination and neither any period of notice nor any payment in lieu thereof upon termination of employment hereunder shall be considered as extending the period of employment for the purposes of vesting of options notwithstanding anything to the contrary in any other agreement between the Corporation and the Executive. Notwithstanding anything contained in this Section 12, in the event of termination by the Corporation other than for Just Cause, the Executive shall have the right to exercise any options which are vested as at the Date of Termination for the 90 Day Period (as defined in Section 11(c)). Any unvested options which would have otherwise vested during such 90 Day Period shall continue to vest during that period and to the extent any unvested options have vested during such 90 Day Period, the Executive shall also be entitled to exercise those options within a rolling 90 day period after the date of vesting of such options, which period will not exceed 180 days following the Date of Termination. In addition, notwithstanding anything contained in this Section 12 or elsewhere in this Agreement, the estate of the Executive shall be entitled, at any time during the period which is 12 months following the date of death of the Executive (the “12 Month Period”), to exercise any options which have vested as at the date of death of the Executive. In addition, any unvested options which would have otherwise vested during such 12 Month Period shall continue to vest during that period and to the extent any unvested options have vested during such period, the Executive’s estate shall be entitled to exercise those options within a period which starts on the day of vesting and ends 12 months from the date of death of the Executive.

For purposes of greater certainty, if the Executive is terminated for Just Cause, death or if the Executive’s employment hereunder is terminated by the Executive pursuant to Section 11(c) then no payment whatsoever shall be made to the Executive under this Section.”

12. Section 14 of the Agreement shall be amended and restated in its entirety as follows:

“14.1 Termination by the Corporation
