    INFORMATION INDUSTRIAL COMPANY LIMITED*                                   
    (a joint stock company incorporated in the People's Republic of China     
    with limited liability)(Stock code: 8205)

    SUBSCRIPTION OF SHARES IN UGL                                             
                                                                              
    On 3 March 2005, the Subscription Agreement was entered into between      
    UGL, Withub HK (a wholly-owned subsidiary of the Company), the Investor   
    and Starwood for (1) the subscription of 540 shares in the share          
    capital of UGL, representing 45% of the enlarged issued share capital     
    of UGL, at the subscription price of US$2,250,000 (equivalent to          
    HK$17,550,000) by Withub HK and (2) the subscription of 540 shares, at    
    the same subscription price, by the Investor.                             
                                                                              
    Since each of total assets ratio and the consideration ratio is more      
    than 5% but less than 25% while the other applicable ratio (being the     
    revenue ratio) is less than 5%, the Withub Subscription constitutes a     
    discloseable transaction for the Company.                                 
                                                                              
    A circular containing further details of the Withub Subscription and      
    the Group will be despatched to the shareholders of the Company as soon   
    as possible.
