In accordance with the AltX Listings Requirements, shareholders are advised of  
the risks of investing in a company listed on AltX and are advised that the JSE 
does not guarantee the viability or the success of a company listed on AltX. In 
terms of JSE Listings requirements a Designated Adviser has to be retained by   
the company. The Designated Adviser is required to, inter alia, attend all board
meetings held by the company to ensure that all JSE Listings Requirements and   
applicable regulations are complied with, approve the financial director of the 
company and guide the company in a competent, professional and impartial manner.
If the company fails to retain a Designated Adviser it must make arrangements to
appoint a new Designated Adviser within 10 business days, failing which the     
company faces suspension of trading of its securities. If a Designated Adviser  
is not appointed within 30 days of its suspension the company faces the         
termination of its listing without an offer to minorities.                      
Shareholders are advised that in the Y3K Group Limited circular to shareholders 
dated 16 May 2005, regarding the acquisition of Information Security Architects 
(Proprietary) Limited, and iSecure (Proprietary) Limited and related matters,   
resulting in the reverse take-over of Y3K Group Limited by Information Security 
Architects (Proprietary) Limited ("the circular"), it was proposed that the     
directors would sell one million ISA shares at 13,396 cents per share to        
employees of ISA via the share incentive trust. This transaction did not take   
place as the employees have left the employ of the company, and consequently the
sale of shares could not be fulfilled. However, in disclosing the transaction in
the circular and the 2005 annual report, disclosure was made as if the directors
had sold their shares, and the employees had purchased the shares via the share 
incentive trust.                                                                
Due to the non-fulfillment of this share sale, the directors" interests in the  
company"s share capital will remain as if the sale of shares had not taken place
and the directors" interest in the company"s securities, as at 31 March 2005 as 
disclosed on page 35 of the circular, is hereby amended and is disclosed as     
follows:
