In accordance with the M&A Framework Agreement (hereinafter referred to as M&A Agreement) signed by Party

A, Party B, Wang Huiling and Gong Yulan on May 18, 2010, Party A shall not implement Article 1.2 unless the conditions specified in Article 1.2.1.1 of M&A Agreement are satisfied.

After Party A’s financial department and Party B verified the 2010 sales revenue of Beijing ITLamp Technology Co., Ltd. (hereinafter referred to as ITLamp) in line with Article 1.2.1.1 of M&A Agreement on Jan. 7, 2011, Party A and Party B reached consent on the following conclusions:

6. However, according to relevant regulations about holding shares of overseas listed companies by domestic natural persons, Party A cannot fully implement Article 1.2 of M&A Agreement, so Party A shall extend an apology to Party B through Party A’s attorney in writing.

Party A and Party B agree to make the following adjustments of Article 1.2 and Article 1.2.1.1 of M&A Agreement through friendly consultation:

Party A shall deliver a partial cash and partial shares of Pansoft Company Ltd to Party B as the payment for the acquisition, with total value of RMB13 million as specified in Article 1.2 of M&A Agreement.

Party A shall assist Party B with registration of an offshore company, as well as registration at relevant domestic authority, and setting up overseas its bank account and brokerage account. Party B shall bear the corresponding expenses.

Party A shall arrange Pansoft Company Ltd to pay 100,000 restricted shares of Pansoft Company Ltd to the offshore company controlled by Party B within two months upon completion of relevant procedures of Party B’s offshore company. The value of 100,000 restricted shares (share price: US$4.2535; exchange rate: 6.6227) of Pansoft Company Ltd is RMB2,816,965.

Party A shall pay cash of RMB 8,183,035 to Party B prior to Mar. 31, 2011, and Party A shall fulfill the obligations of withholding personal income tax and deduct Party B’s borrowing of RMB400,000, so Party A shall actually pay RMB 6,226,428 to Party B.
