                                   PUBLIC Q&A

      ANNOUNCEMENT HIGHLIGHTS

      Q: WHAT DID ONYX ANNOUNCE?

      On November 12, 2003 Onyx announced an unsolicited proposal to acquire
Pivotal Corporation.

      Q: WHY DID ONYX DECIDE TO ACQUIRE PIVOTAL?

      Acquiring Pivotal increases our strong leadership in the CRM mid-market
and we believe it will accelerate our profitable growth. After the acquisition
Onyx will be the second largest pure-play CRM company with 2,600 customers and
over $110 million in annual revenues. In addition, we believe that our proposal,
which represents a 26% premium over the existing offer, is a better alternative
for Pivotal's shareholders and customers.

      Q: WHAT ARE THE TERMS OF THE OFFER?

      Under the terms of the proposal, Onyx would exchange 0.475 shares of Onyx
Software common stock for each common share of Pivotal Corporation. Based on the
closing price of Onyx common stock on November 11, 2003 of $4.73, this proposal
equates to $2.25 for each share of Pivotal common stock, or a 26% premium over
the existing offer to Pivotal shareholders. Additionally, the transaction would
be structured to enable Pivotal shareholders to defer tax on the transaction
until they ultimately dispose of their shares of Onyx common stock.

      Q: WHAT IS THE TIMING OF THE OFFER?

      Onyx would propose an aggressive closing timeline in order to combine our
respective companies as quickly as practical.

      Q: HOW LONG WILL THE OFFER REMAIN OPEN?

      We have asked the Pivotal Board of Directors to respond to our proposal by
Friday, November 14(th) at 2:00 pm Pacific Standard Time.

      Q: WILL YOUR OFFER BE SUBJECT TO ANY CONDITIONS?

      Our proposal is conditioned on the termination of the Talisma agreement
prior to the closing of that transaction and the execution of a definitive
agreement between Pivotal and Onyx. In addition, the offer will be subject to
regulatory requirements of the United States Securities and Exchange Commission
and the Nasdaq National Market.


                                      -3-



      Q: HOW DOES THE ONYX OFFER COMPARE TO THE RECENTLY ANNOUNCED OFFER FROM
OAK INVESTMENT PARTNERS?


      We believe the Onyx proposal is superior for Pivotal shareholders and
customers for the following reasons:

- Our proposal is 26 percent higher than the existing offer, based on the
closing price of Onyx stock on November 11, 2003.

- Our offer gives Pivotal shareholders a similar investment vehicle -- stock in
a CRM vendor -- with a significant potential upside.

- The Onyx-Pivotal combination would be larger than the proposed Pivotal-Talisma
entity and allow for economies of scale

- We believe that Onyx has a better operational profile than Pivotal or Talisma:
a more experienced and stable management team, strong financial leadership and
performance, and industry-respected technology leadership.

      ABOUT THE BUSINESS COMBINATION

      Q: HOW WILL THE COMBINED COMPANIES BE POSITIONED IN THE MARKET?

      Acquiring Pivotal increases our leadership in the CRM mid-market. The
combined entity will have over 2600 customers and more than $110 million in
revenues, making it the second largest pure play CRM vendor behind Siebel. In
addition, a combined Onyx-Pivotal organization would have strength in key market
segments such as financial services, healthcare, government, and technology.

      Q: HOW MUCH OVERLAP EXISTS BETWEEN ONYX'S MARKET FOCUS AND PIVOTAL'S
MARKET FOCUS?

      Although Onyx and Pivotal compete in the same general market (mid-market
CRM), we overlap slightly. Onyx focused on the mid-market and up into enterprise
size customers while Pivotal focuses on the mid-market and below.

      Q: HOW MANY EMPLOYEES WILL BE IN THE COMBINED COMPANY?

      Following completion of the acquisition a more detailed staffing plan will
be developed that takes into consideration the operations of both companies.
Onyx would expect to increase investments in strategic sales, marketing and R&D
initiatives while reducing the combined companies' G&A expenses.

      Q: WHAT NAME WILL THE COMBINED COMPANY OPERATE UNDER?


      The combined entity will operate under the Onyx Software brand and be
headquartered in Bellevue, Washington.

      FOR PIVOTAL CUSTOMERS

      Q: WHAT IMPACT DOES THE MERGER HAVE ON PIVOTAL CUSTOMERS?

      Onyx has a heritage of outstanding customer support, the industry's
highest customer satisfaction ratings, and a self-confessed obsession for
helping our customers experience CRM success. This means that the investment
Pivotal customers have made in CRM will be shepherded by a company with a
long-term commitment to the CRM industry and a domain expertise relevant to
their business needs.

      Q: WHAT WILL HAPPEN TO THE PIVOTAL PRODUCT LINE?

      Onyx will continue to provide support for Pivotal's product line after the
acquisition. We have a heritage of outstanding customer support, and extending
that satisfaction to Pivotal's customers will be the driver in ongoing product
related decisions..

      Q: WILL PIVOTAL CUSTOMERS BE FORCED TO MIGRATE TO ONYX?


      No. Onyx intends to support the Pivotal product line, although we believe
that Pivotal customers who require an Internet-architected solution will find
that Onyx is ahead of the technology curve with a solution TODAY that exceeds
the functionality of client-server CRM offerings. We intend to create
integration packages between the products.

      ABOUT ONYX

      Q: WHAT IS THE HISTORY OF ONYX?

      Onyx was founded in 1994 and was the first CRM vendor to provide an
integrated suite of marketing, sales and service solutions. In addition to the
core CRM platform, Onyx stable of offerings includes solutions for partner
relationship management, online collaboration, contact centers, and business
intelligence. Onyx provides a robust, enterprise strength application with that
is both scalable and flexible enough to accommodate the unique business
requirements of each of its customers, yet does so in a manner that allows for
rapid deployment and low TCO. The average implementation time for Onyx is 16
weeks, and we believe that the implementation costs for Onyx are one third that
of the leading competitor.

      Onyx has a strong legacy of mid-market leadership, and has been
consistently recognized for maintaining high levels of satisfaction within its
customer base. In fact, in a recent survey by Peerstone Research, 91% of Onyx
customers indicated that if they had to start all over with their CRM project,
they would once again choose Onyx. In 2003 alone, Onyx was recognized for its
leadership in mid-market CRM by Gartner and was named the #1 mid-market CRM
vendor by CRM Magazine.

      Onyx also has a reputation for technology innovation. Onyx was one of the
first CRM vendors to re-architect its application to a true, 3-tier, Internet
architecture, and as


                                      -5-


a result our current application exceeds the feature set delivered by our
previous client server application. More than 65% of our customers have migrated
to a web-based version of Onyx. Today Onyx CRM is delivered via a 4(th)
generation web-based platform that is completely web services enabled, making it
easier to deploy, manage, customize and integrate with other IT systems.

the top 6 asset management firms in the world utilize Onyx, including State
Street, Dreyfus, and Strong Capital. Onyx also has a leading presence in
healthcare, with customers like Regence, UPMC, HealthNow, and VHA. In the
Government Sector, Onyx is one of the top three providers of solutions to local
governments in the United Kingdom and has an emerging presence at the state
level in the US. More than 150 technology companies use Onyx, and global
organizations like Starbucks, Amway, American Express, Microsoft, NTL, and
Airborne Express have chosen Onyx.

      OPEN LETTER TO PIVOTAL CUSTOMERS

      As you may know, Onyx Software has a legacy of outstanding customer
support, the industry's highest customer satisfaction ratings, and a
self-confessed obsession for helping our customers experience CRM success. On
becoming a member of the Onyx family, I pledge to you that our very first
initiative will be to aggressively engage with you to see how we can drive even
more value into your existing CRM investment. When we submitted our proposal to
acquire Pivotal, we considered Pivotal's customer to be its biggest asset. As an
Onyx customer, be assured that you will receive all the consideration and care

      [The following communication was sent to industry anaysts via email]

      Greetings,

      This morning Onyx submitted an unsolicited bid to acquire Pivotal at a 26%
premium over the existing offer from Talisma, as financed by Oak Investment
Partners. We made this proposal because we believe the time is right to
consolidate the CRM midmarket and we believe Onyx can leverage Pivotal's assets
better than anyone else in this space.

      The offer further demonstrates our commitment to serving the CRM
mid-market and, if accepted, we believe it would accelerate our profitable
growth. We firmly believe that this is a superior proposal for Pivotal's
shareholders and customers as the combined company would be the second largest
independent CRM company with over 2600 customers, more than $110 million in
annual revenues and significant geographic coverage.

      The combination clearly makes a lot of sense. Onyx and Pivotal both
understand the midmarket and its desire for more than the generic functionality
of low-end solutions and fear of complex, costly-to-implement software. We share
a legacy of development on the Microsoft platform. We both sell broadly to a
variety of industries, yet we also each have dedicated efforts to focus on
specific verticals.

      In addition, we see this as a tremendous opportunity for Pivotal
customers.

      -     The investment Pivotal customers have made in CRM will be shepherded
            by a company with a long-term commitment to the CRM midmarket.

      -     Onyx has a legacy of providing superior customer service, and we are
            consistently at the top of independent surveys for customer
            satisfaction.

      -     We have a fourth-generation Internet platform that TODAY exceeds the
            functionality of our client-server product line. Pivotal customers
            may leverage that capability immediately.

      I want to make sure that you are able to connect personally with one of
our executives to discuss this exciting news. Please contact Dan Reidy of our PR
agency (contact info below), who can arrange some time.
