CDC Software Proposes Increased Offer to the Shareholders of Onyx

Hong Kong, Atlanta, June 20, 2006 — CDC Corporation (NASDAQ: CHINA ; website: www.cdccorporation.net) today announced that CDC Software, a wholly owned subsidiary of CDC Corporation, is making a superior proposal to the board of directors of Onyx Software (NASDAQ: ONXS) for a strategic transaction that would combine Onyx Software with CDC Software.

Subject to CDC Software being granted the opportunity to conduct and complete due diligence to its satisfaction, under the terms of CDC Software's new proposal, each Onyx shareholder would have a choice to receive, for each Onyx share, consideration consisting of either (a) all-cash or (b) cash-and-shares in CDC Corporation.

In the event an Onyx shareholder elects to receive all-cash consideration, such shareholder would receive, for each Onyx share, $4.85 per share in cash. In the event an Onyx shareholder elects to receive cash-and-shares, such shareholder would receive, for each Onyx share, $5.00 per share comprised of 50 percent (or $2.50) in cash and 50 percent (or $2.50) in registered Class A Common Shares of CDC Corporation. The proposal represents a premium of up to 4.2% in excess of the publicly announced offer made by M2M of $4.80 per share in cash, excluding the effect of the $4.5 million in break-fees and expenses Onyx would be required to pay to M2M. It is estimated that based upon approximately 18.5 million Onyx shares outstanding, the break-fees and expenses Onyx would be required to pay to M2M amount to in excess of $0.24 per Onyx share.

CDC Software's management awaits a response from the independent members of Onyx's board of directors to its proposal.

"We remain firm in our belief in the benefits of a combination, particularly between our Pivotal CRM division and Onyx," said Eric Musser , executive vice president of strategy, mergers and acquisitions for CDC Software. "This potential combination harbors benefits for both shareholders and customers of Onyx, including complementary industry specialization, products, geographic markets, sales channels and marketing strategies."

Mr. Musser added. "As an Onyx shareholder, we were disappointed to see the unusually high break-fees and expense obligations in their current M2M agreement. As we have indicated in recent months, we remain flexible and open to exploring options with the Onyx management team, assuming that we have the opportunity to perform due diligence under the conditions afforded to other interested parties. In the interest of maximizing the value for their shareholders, we hope that the Onyx board of directors will give due consideration to our proposal."

The management of CDC Software believes that its proposal is superior to all outstanding offers for Onyx, given the per share price being offered, the liquidity and appreciation in value of CDC Corporation stock, its strong cash position, and the continuing growth in its revenues and profitability. CDC Software urges Onyx's board of directors to consider this proposal, and provide CDC Software with the opportunity to conduct due diligence as other potential acquiring companies have had.

This communication is not a solicitation of a proxy from any security holder of Onyx. Nor is this communication an offer to purchase or a solicitation of an offer to sell securities.
