For the purposes hereof:


 


	 	“control person” has the
    meaning ascribed to that term in securities legislation except in Manitoba, Ontario, Quebec, Nova Scotia, Newfoundland and Labrador,
    Prince Edward Island, the Northwest Territories and Nunavut where “control person” means any person that holds or is
    one of a combination of persons that hold:

     

	 	(i)              
     	a sufficient number of any of the securities
    of an issuer so as to affect materially the control of the issuer; or
	 	(ii)            
     	more than 20% of the outstanding voting securities
    of an issuer except where there is evidence showing that the holding of those securities does not affect materially the control of
    that issuer;

     

	 	“eligibility adviser” means:
	 	 
	 	(i)              
     	a person that is registered as an investment
    dealer or in an equivalent category of registration under the securities legislation of the jurisdiction of a Subscriber and authorized
    to give advice with respect to the type of security being distributed; and
	 	(ii)            
     	in Saskatchewan or Manitoba, also means a
    lawyer who is a practicing member in good standing with a law society of a jurisdiction of Canada or a public accountant who is a
    member in good standing of an institute or association of chartered accountants, certified general accountants or certified management
    accountants in a jurisdiction of Canada provided that the lawyer or public accountant must not:
	 	(A)         
     	have a professional, business or personal relationship with the issuer, or
    any of its directors, executive officers, founders or control persons; and
	 	(B)         
     	have acted for or been retained personally
    or otherwise as an employee, executive officer, director, associate or partner of a person that has acted for or been retained by
    the issuer or any of its directors, executive officers, founders or control persons within the previous 12 months;

     

	 	“financial assets” means
    (i) cash, (ii) securities or (iii) a contract of insurance, a deposit or an evidence of a deposit that is not a security for the
    purposes of securities legislation. These financial assets are generally liquid or relatively easy to liquidate. The value of a purchaser’s
    personal residence would not be included in a calculation of financial assets;

     

	 	“financial statements”
    for the purposes of paragraph (m) of the “accredited investor” definition must be prepared in accordance with generally
    accepted accounting principles;

     

	 	“founder” means, in respect of an issuer, a
    person who:
	 	 
	 	(i)              
     	acting alone, in conjunction or in concert
    with one or more persons, directly or indirectly, takes the initiative in founding, organizing or substantially reorganizing the
    business of the issuer; and
	 	(ii)            
     	at the time of the trade is actively involved
    in the business of the issuer;

     

	 	“fully managed account”
    means an account of a client for which a person makes the investment decisions if that person has full discretion to trade in securities
    for the account without requiring the client’s express consent to a transaction;

     

	 	“investment fund” has
    the meaning ascribed thereto in National Instrument 81-106 - Investment Fund Continuous Disclosure;

     

	 	  “net assets” means all of the purchaser’s
    total assets minus all of the purchaser’s total liabilities. Accordingly, for the purposes of the net asset test, the calculation
    of total assets would include the value of a purchaser’s personal residence and the calculation of total liabilities would
    include the amount of any liability (such as a mortgage) in respect of the purchaser’s personal residence. To calculate a purchaser’s
    net assets under the “accredited investor” definition, subtract the purchaser’s total liabilities from the purchaser’s
    total assets (including real estate). The value attributed to assets should reasonably reflect their estimated fair value. Income
    tax should be considered a liability if the obligation to pay it is outstanding at the time of the distribution of the security;
     



 






     

    


    

 


	 	“related liabilities” means:
	 	 
	 	(i)              
     	liabilities incurred or assumed for the purpose of financing the
    acquisition or ownership of financial assets; or
	 	(ii)            
     	liabilities that are secured by financial
    assets;

     

	 	“spouse” means an individual who:
	 	 
	 	(i)              
     	is married to another individual and is not living separate and apart within
    the meaning of the Divorce Act (Canada), from the other individual;
	 	(ii)            
     	is living with another individual in a marriage-like relationship, including
    a marriage-like relationship between individuals of the same gender; or
	 	(iii)          
     	in Alberta, is an individual referred to
    in paragraph (i) or (ii) immediately above or is an adult interdependent partner within the meaning of the Adult Interdependent
    Relationships Act (Alberta); and
