                FINANCIAL MARKETS SHOW SUPPORT FOR ONYX PROPOSAL
            3.9 Million Pivotal Shares Trade Between $1.97 and $2.10

BELLEVUE, Wash -- Onyx(R) Software Corp. (NASDAQ: ONXS), a worldwide leader in
successful CRM, today noted that the financial market reaction suggests strong
support for the Onyx proposal to acquire Pivotal Corporation. On the day of the
Onyx announcement, the price of Pivotal stock gapped up to as high as $2.10 and
traded no lower than $1.97 with NASDAQ reported volume exceeding 3.9 million
shares. Additionally, Pivotal stock gapped up to as high as CAN$2.75 and traded
no lower than CAN$2.57 with 476,800 shares traded on the Toronto Stock Exchange.
In both Nasdaq and Toronto markets, the high, low and closing prices of Pivotal
common stock on the day the Onyx proposal was announced were substantially
higher than the value of the Talisma offer and the prices at any time since the
announcement of the Talisma offer.

"The market as a whole appears to agree that the Onyx proposal is superior to
the existing offer from Oak," said Onyx Software CEO Brent Frei.

The Onyx proposal is not contingent on financing. Onyx Software achieved
non-GAAP profitability in recent quarters and believes that it has adequate
financing to complete the transaction and to grow the business of the combined
entity. "We expect that Pivotal's board will soon exercise their fiduciary duty
to review what we believe is a superior proposal," Frei added.

BACKGROUND: Onyx announced on November 12 an unsolicited proposal to acquire
Pivotal Corporation (NASDAQ: PVTL and TSE:PVT) by way of a business combination
in a stock for stock transaction valued at approximately $2.25 per Pivotal
common share. Under the terms of the proposal which was submitted by letter to
the Pivotal Board of Directors this morning and is included with this press
release, the companies will 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 of $2.25 is based on the $4.73 closing price of Onyx common stock on
November 11, 2003.

On October 8, 2003 Pivotal announced that it had entered into a definitive
agreement to be acquired by Talisma Corporation in a cash transaction financed
by Oak Investment Partners valued at $1.78 per share. The Talisma transaction is
still pending and is scheduled for a shareholder vote on November 18, 2003. The
Onyx proposal represents a 26% premium over the Talisma offer. The Onyx proposal
is structured to provide potential tax deferral

benefits to investors compared to the existing offer. Onyx has not at this time
commenced an exchange offer for Pivotal shares.
