      behalf of the Company and such decision is based entirely
      upon a review of any public information which has been filed by the

	 	(k) 	
      the Company has advised the Subscriber that the Company

      Exchange;

	 	 	 	 
	 	(m) 	
      the Subscriber is outside the United States when

	 	(s) 	
      the Subscriber is purchasing the Shares pursuant to an
      exemption from the registration and the prospectus requirements of
      applicable securities legislation on the basis that the Subscriber is an
      insider of the Company and, as a consequence:

	 	 	 	 
	 		(i) 	
      is restricted from using most of the civil remedies
      available under securities legislation,

	 	 	 	 
	 		(ii) 	
      may not receive information that would otherwise be
      required to be provided under securities legislation, and

	 	 	 	 
	 		(iii) 	
      the Company is relieved from certain obligations that
      would otherwise apply under securities legislation;

	 	 	 	 
	 	(t) 	
      the statutory and regulatory basis for the exemption
      claimed for the offer and issuance of the Shares, although in technical
      compliance with Regulation S, would not be available if the offering is
      part of a plan or scheme to evade the registration provisions of the 1933
      Act; and

	 	 	 	 
	 	(u) 	
      this Agreement is not enforceable by the Subscriber
      unless it has been accepted by the Company.
