CDC Software Submits Letters to Onyx and SEC Regarding Proposed Acquisition of Onyx

Hong Kong, Atlanta, June 22, 2006 — CDC Software, a wholly owned subsidiary of CDC Corporation (NASDAQ: CHINA), today announced that it has submitted letters to the board of directors of Onyx Software and to the SEC regarding its proposed acquisition of Onyx.

In its letter to the board of directors of Onyx, CDC Software reiterates its proposed superior competing transaction announced on June 20, 2006. The letter also raises conflict of interest issues created by the unusually high breakup fees, estimated at $0.24 per Onyx share, in the definitive agreement with M2M Holdings. As a concerned Onyx shareholder, CDC Software requests that the break fees be abandoned so that the fees can be paid to Onyx shareholders, rather than to M2M Holdings, through the course of the proposed acquisition by CDC Software. CDC Software is prepared to challenge the breakup fees in court, if it enters into a definitive agreement with Onyx. The company is awaiting a reply from the independent directors of Onyx and ready to commence negotiations.

In the letter to the SEC, CDC Software expresses its concern that Onyx may have failed to adequately consider prior proposals from CDC Software because M2M Holdings intends to keep the current Onyx management in place.
