through issuing instruments such as common shares, DRs (including but not limited to ADS), or
Euro/Domestic convertible bonds (including secured or unsecured corporate bonds), based on market
conditions and the Company&#146;s needs. The amount of shares issued or convertible is proposed to be no
more than 10% of total share issued (i.e., no more than 1,269,208,166 shares)


<P align="left" style="font-size: 12pt; text-indent: 1%">(2)&nbsp;According to item 6, Article&nbsp;43-6, Security and Exchange Act, the private placement
offering shall be conducted in separate instances within one year after AGM approval.


<P align="left" style="font-size: 12pt; text-indent: 1%">(3)&nbsp;The approval will expire on 2015/6/10. Considering changes from market conditions, the
Board has resolved to terminate the private placement offering.

private placement. So the Company proposed to raise capital through private placement, rather than
