2. Such extension shall not amount to breach of the Equity Transfer Agreement, and Logic shall not assume any liability arising out of the extension.

3. Article 2 of the Supplemental Agreement of the Equity Transfer Agreement entered into on December 12, 2008 among Party A, Party B and Party C regarding distribution of the profit shall be amended to the following:

The parties agreed that (i) if Logic will have paid 90% of the purchase price (or RMB 174,960,000) on or before April 7, 2009, then Logic will be entitled to its share of Dalin's portion of the profit generated by Qianfeng starting from January 1, 2009, and (ii) if Logic fails to pay the said amount, the profit generated by Qianfeng from Janaury 1, 2009 until the day of payment of said amount will be shared by Party A and Party B (i.e., Logic will be entitled to its share of Dalin’s portion of the profit generated by Qianfeng calculated according to the proportion of the purchase price paid by it, and Party A will be entitled to the rest of Dalin’s portion of the profit generated by Qingfeng).

This Amendment shall be executed in six copies with two copies for each of Party A, Party B and Party C. This Amendment shall be effective and legally binding upon execution.
