 INDEMNITY FOR TAXES

 I confirm and warrant that I will save, hold harmless and indemnify the Corporation from and against all claims, taxes or penalties and demands which
may be made by the Minister of National Revenue requiring the Corporation to pay income tax under the Income Tax Act (Canada), and/or by the U.S. Internal Revenue Service and/or State taxing authorities requiring the Corporation to pay or

Corporation on my behalf. 
 BENEFITS AND INSURANCE CLAIMS 
 I acknowledge and understand that the Corporation will discontinue all of my employment benefits effective [date]. I further acknowledge and agree that I have no further claim against the Corporation for benefits or damages arising from the

disclose, directly or indirectly, the contents of this Release or the terms of settlement relating to my ceasing to be employed with the Corporation to any person, including but without limiting the generality of the foregoing, to employees or

officers’ liability insurance. 

 NO ADMISSION 
 I acknowledge that payment of the consideration set out above does not constitute any admission of liability by or on behalf of the Released Parties. 
 INDEMNITY FOR TAXES 
 I confirm and warrant that I will save, hold harmless and indemnify the Corporation from and against all claims, taxes
or penalties and demands which may be made by the Minister of National Revenue requiring the Corporation to pay income tax under the Income Tax Act (Canada), and/or by the U.S. Internal Revenue Service and/or State taxing authorities
requiring the Corporation to pay or withhold income tax under U.S. or State tax laws, in respect of income tax payable in excess of the income tax previously withheld and with respect to any other income tax which may, in the future, be found to be
payable or to be withheld by the Corporation on my behalf. 
 BENEFITS AND INSURANCE CLAIMS 
 I acknowledge and understand that the Corporation will discontinue all of my employment benefits effective [date]. I further acknowledge and agree that I have no further
claim against the Corporation for benefits or damages arising from the cessation of benefits and that I have been provided with information concerning: 
  

	 	(a)	any available right to continue any such benefits, at my own expense under the U.S. COBRA law; and 

  

	 	(b)	any available right to convert my life insurance coverage to an individual policy of life insurance at my own expense. 

  

 - 14 - 

 I fully accept sole responsibility to replace those benefits that I wish to continue and to exercise conversion
privileges where applicable with respect to benefits. In the event that I become disabled, I covenant not to sue the Corporation for insurance or other benefits, or for loss of benefits. I hereby release the Released Parties from any further
obligations or liabilities arising from my employment benefits. 
 NON-DISCLOSURE 
 I agree that I will not divulge or disclose, directly or indirectly, the contents of this Release or the terms of settlement relating to my ceasing to be employed with the Corporation to any person, including but
without limiting the generality of the foregoing, to employees or former employees of the Corporation, except my legal and financial advisors and my immediate family, on the condition that they maintain the confidentiality thereof, except as may be
required by law. 
 CONFIDENTIALITY and NON–SOLICITATION 
 I acknowledge and agree that I continue to be bound by Clause 5 of the Employment Agreement, a copy of which is attached. 
 FURTHER CLAIMS

 I agree that I will not make claim or take proceedings against any other person or entity that might claim contribution or indemnity under the
provisions of any statute or otherwise against the Corporation or any individual or entity discharged through this Release. 
 EFFECT OF RELEASE

 I understand and agree that by signing this Agreement, I - on behalf of myself, my family, assigns, representatives, agents, estate, heirs,
beneficiaries, executors, administrators, successors, and/or attorneys, if any - agree to give up any right or entitlement I may have under U.S. or Canadian federal, state, provincial or local law against the Released Parties, concerning any events
related to my employment or termination, or the Corporation’s failure to continue my employment. This Agreement extinguishes any potential employment discrimination claims I may have relating to my employment with the Corporation and the
Corporation’s termination of my employment existing on the date I sign this Agreement. 
 I further represent and warrant that I have not assigned to
any third party any claim involving the Released Parties or authorized any third party to assert on my behalf any claim against the Released Parties. If a third party asserts a claim against the Released Parties on my behalf or includes me as a
class member in any class action involving any claim, I agree to not accept any benefits or damages relating or arising out of such claim. 
 COOPERATION

 For a reasonable period after my termination, I agree to make myself available and to reasonably cooperate with the Corporation in any future claims or
lawsuits involving the Released Parties where I have knowledge of the underlying facts or to affect the completion of my outstanding employment duties or the transfer of such duties. The Corporation agrees to reimburse me for time I spend at the
Corporation’s request at a rate per hour equivalent to what I earned with the Corporation immediately before my notice of termination. Any obligations performed to affect the completion or transfer of my 
  

 - 15 - 

 duties shall be performed as an independent contractor, not as an employee. I will not be reimbursed if I am a named
party in any claim or lawsuit. In addition, I agree not to voluntarily aid, assist or cooperate with any claimant or plaintiff or their attorneys or agents in any claim or lawsuit commenced against the Released Parties. 
 Nothing in this Agreement should be construed to prevent me from initiating or participating in any U.S. or Canadian federal, state, provincial or local agency
administrative proceeding or from testifying at an administrative hearing, deposition, or in court in response to a lawful subpoena. 
 UNDERSTANDING

 I acknowledge that this Release may be enforced in any court, federal, state, provincial, or local, and before any administrative agency or body,
federal, state, provincial, or local. I hereby declare that I have had the opportunity to seek independent legal advice with respect to the matters addressed in this Release and the terms of settlement which have been agreed to by the Corporation
and me, and I fully understand this Release and the terms of settlement. I hereby voluntarily accept the terms for the purpose of making full and final compromise, adjustment and settlement of all claims as aforesaid. 
 COMPLETE AGREEMENT 
 I understand and agree that this Release contains
the entire agreement between the Released Parties and me regarding the aforesaid matters and that the terms of this Release are contractual and not a mere recital. 
 REVIEW PERIOD, EXECUTION, AND REVOCATION 
 I understand that I can have 21 calendar days from my receipt of this Agreement to consider
whether to accept its terms. I agree that changes to this Agreement, whether material or immaterial, do not restart the running of the 21-day period. After signing the Agreement, I will have seven (7) calendar days to consider whether to revoke
it. The Agreement will not be effective until seven (7) calendar days after I sign the Agreement without revoking it.

                            . 
 EFFECTIVE PERIOD 
 This Agreement is null and void if: (i) I fail to execute and return it within 21 days of
receipt; or (ii) I sign it within 21 days, but revoke my execution within seven (7) calendar days after signing it. 
 DATED at                     ,              effective the
             day of             , 200    .
