Onyx Software Expects Substantially Improved Earnings for Onyx-Pivotal Combination
Pivotal Board of Directors Continues to Review the Onyx Proposal

BACKGROUND
On November 12th Onyx announced an unsolicited proposal to acquire Pivotal Corporation by way of a business combination in a stock for stock transaction. Under the terms of the proposal, the companies would be combined on the basis of 0.475 shares of Onyx Software common stock for each common share of Pivotal Corporation, or approximately 12.5 million shares of Onyx. The approximate price per Pivotal share is $2.25 based on the $4.73 closing price of Onyx common stock on November 11th. Onyx Software made its unsolicited proposal after being excluded from the Pivotal company-sale process.

POSITIVE REACTION TO THE ONYX PROPOSAL
In the two trading sessions since Onyx Software's announcement, the NASDAQ trading volume in Pivotal stock exceeded 5.8 million shares and 0.6 million shares were traded on the Toronto Stock Exchange -- all at prices well in excess of the existing $1.78 Talisma offer - strongly indicating that the financial community believes that the Onyx proposal is superior.

"In addition to the strong support that the financial markets have shown for Onyx Software's proposed business combination with Pivotal, we are encouraged by positive comments made by a broad variety of CRM industry observers," said Frei. These published comments can be reviewed at: www.onyx.com/newsandevents/pivotalinfo/comments.asp.

FINANCIAL SYNERGIES ARE SUBSTANTIAL
Onyx reported revenue of $15.4 million and non-GAAP operating income in the most recent quarter. Onyx also sequentially increased its quarterly license revenue. In the same period, Pivotal's revenue was $13.3 million with a non-GAAP operating loss.

Onyx believes that the expected quarterly incremental profits and cash flows resulting from the proposed business combination with Pivotal would likely approach $2 million as early as one to two full quarters following the acquisition. Onyx expects to incur transaction costs, restructuring, and a break-up fee as part of the acquisition. Onyx believes that these impressive results can be achieved even while Pivotal's revenue would initially be disrupted as a result of the merger uncertainties. Over time, Onyx expects that incremental revenues as a result of this transaction would exceed Pivotal's current revenues.

Onyx expects to make investments in several strategic areas of the combined entity. Those areas include increasing investment in targeted verticals, expanding Onyx Embedded CRM to Pivotal's partners, and increasing spending on customer account management and product support for Pivotal customers.

Onyx expects to generate substantial savings through the elimination of many redundant operations and organizational structures. For example, in aggregate Onyx and Pivotal spent $4.5 million on general and administrative expenses in the most recent quarter. The larger combined entity should be able to achieve a target expense ratio of 10% of revenue, resulting in a potential reduction of up to $2 million per quarter in general and administrative expenses alone.

Cost savings in areas outside of general and administrative expense could be at least $2 million per quarter. While the combined entity will benefit from geographic sales coverage of the two companies that is complementary in many cases, there is also significant opportunity to eliminate overlap of sales offices and the infrastructure to support field operations. In marketing, the combined entity would benefit from the power of advertising, public relations and marketing efforts combined behind a unified corporate brand. In research and development, the combined entity would focus efforts on a rationalized product that maintains the best aspects of both product lines.

COMBINATION ENHANCES ONYX SOFTWARE'S LEADING MIDDLE-MARKET POSITION
The combined entity will be the second largest pure-play CRM vendor in terms of revenue and Onyx's position in the highly-sought after middle-market segment would be enhanced. Onyx believes that the Onyx-Pivotal combination will result in tremendous operating leverage, providing upside potential to Pivotal investors that is not a possibility under the terms of the Talisma cash offer. This upside is in addition to the initial premium for Pivotal shareholders implicit in the Onyx proposal.

"We look forward to further discussing with Pivotal's Board of Directors the strategic and financial opportunities that a combination with Onyx would offer shareholders in both companies," said Brian Henry, Onyx Software CFO and Executive Vice President.
