The following is the text of a joint press release issued by CrossWorlds and
IBM on October 30, 2001:

                IBM AND CROSSWORLDS SIGN AGREEMENT FOR SALE OF
                          CROSSWORLDS BUSINESS TO IBM
     Acquisition Strengthens IBM's WebSphere Integration Software Business

Armonk, N.Y., and Burlingame, CA., October, 30, 2001 -- IBM (NYSE:IBM) and
CrossWorlds Software, Inc. (NASDAQ:CWLD) today announced the two companies
have entered into a definitive agreement for IBM to acquire CrossWorlds in a
cash transaction valued at $129 million.

The acquisition further strengthens IBM's business in the fast-growing
e-business infrastructure software segment, a key strategic priority for the
company. IBM's WebSphere e-business infrastructure software revenue grew 75%
year-to-year in the third quarter of 2001 -- the tenth consecutive quarter of
double-digit growth. And MQSeries, IBM's integration software, grew 129% in
the same time period.

According to IDC, software supporting the unique business-process integration
requirements of specific industries, such as CrossWorlds' products, represents
the fastest growing sub-segment of e-business infrastructure software with
annual growth of 25%. IDC estimates the opportunity for this sub-segment will
be $4 billion by 2005.

The acquisition extends the unparalleled breadth of IBM's portfolio of
e-business infrastructure software, known as middleware. And it addresses a
key customer need for solutions that include both application server and
integration software.

CrossWorlds is a leading provider of software enabling companies to automate
business processes that integrate multiple applications, such as those for
managing customer relationships and supply chains as well as enterprise
resource planning.

CrossWorlds' software, which supports open Internet standards such as J2EE and
XML, also helps businesses integrate processes unique to individual industries
such as the telecommunications, financial services and industrial sectors,
improving the efficiency and productivity of internal operations as well as
trading relationships.

Through a long-term partnership, CrossWorlds' software has been integrated
over the last four years with WebSphere middleware products. For example,
CrossWorlds has an OEM agreement with IBM for MQSeries and has added WebSphere
Application Server software connectivity to its products.

CrossWorlds, based in Burlingame, California, has 350 employees and a broad
group of customers, such as Caterpillar, Siemens and the Whirlpool
Corporation. These customers use CrossWorlds and IBM WebSphere products as
their e-business infrastructure.

"Our customers have two primary requirements for e-business infrastructure
software -- managing high- volume transactions and the integration of business
processes," said Steve Mills, senior vice president and group executive, IBM
Software Group. "WebSphere helps 50,000 customers around the world manage
billions of transactions per day while also integrating business processes.
CrossWorlds increases our strength in integration software for a wide range of
industries -- helping companies solve specific business-process integration
problems across the range of integration points unique to their industry."

"We are very excited to have our leading solution become a key integration
element within the WebSphere software platform," said Fred Amoroso, president
and chief executive officer at CrossWorlds Software. "We believe the
combination of CrossWorlds' leadership in business process integration, IBM's
leadership in messaging integration and e-business infrastructure, and our
shared commitment to customer dedication will create an unmatched value
proposition within the industry."

Once the acquisition is completed, IBM will:





                                                                             3

     o    Integrate CrossWorlds' business operations and personnel into the
          existing IBM division responsible for business integration software,
          which is led by General Manager Ambuj Goyal;

     o    Market and sell CrossWorlds' integration software products worldwide
          through an integrated IBM and CrossWorlds software sales force;

     o    Extend investments in CrossWorlds products for current customers and
          ISVs; and

     o    Expand the opportunity for implementation services and extend the
          current partnerships with leading global systems integrators (GSIs).

In addition, IBM Global Services will include services capability for
CrossWorlds software in its worldwide Enterprise Application Integration
practice.

The acquisition is subject to CrossWorlds shareholder and regulatory
approvals, and is expected to close in the first quarter of 2002.

     In connection with the merger, CrossWorlds Software will be filing a
proxy statement with the Securities and Exchange Commission. STOCKHOLDERS OF

         On October 30, 2001, CrossWorlds Software delivered the following
letter to its employees with respect to the merger:

         Dear CrossWorlds Colleague:

         We are very excited to tell you that today IBM announced a definitive
agreement to acquire CrossWorlds Software. With that, we would like to share
some thoughts on the enormous opportunity that lies ahead of us.

         CrossWorlds' leadership in business process integration technology,
along with IBM's brand recognition and channel reach in the marketplace, makes
for a winning combination. CrossWorlds' reputation as a company priding itself
on technology excellence and customer commitment is extremely important to
IBM's goal of extending its leadership position in the middleware sector. IBM
has industry-leading middleware products, brand loyalty, partner channels and
a dedicated sales team currently numbering 8,000 worldwide -- all resources
that will complement CrossWorlds' strengths.

         IBM and CrossWorlds share a common culture and value for people and
technology. Like IBM, CrossWorlds has developed a customer-centric culture
that's focused on long-term relationships, support of production applications
and a strong commitment to win.

         We also share some of the same customers, including Whirlpool,
Caterpillar and Siemens. IBM is committed to protecting the investment of our
common customers. At the same time, all CrossWorlds customers will have the
financial backing and market reach of IBM to protect their business process
integration investment. And as business partners for the past four years,
CrossWorlds and IBM have established a strong connection that should make for
an easy transition once the deal closes.

         From a timing standpoint, we anticipate that the CrossWorlds
acquisition will close early in 2002. Once the acquisition is complete, we
will do everything possible to work with you, our customers, and partners.

         Rob Lamb, the transition executive managing the integration, along
with a leadership team of IBM and CrossWorlds executives, will help you in the
transition from CrossWorlds to IBM. We've also created an extranet site as a
way to introduce you to IBM. It will help inform you on issues like employee
benefits, the marketplace, the latest news, earnings reports, etc. See below
for details.

         IBM and CrossWorlds are impressive as separate entities. With our
complementary business integration technology, together, we have the ability
to reach great heights in this high-growth sector.

         Sincerely,

         /s/ Fred Amoroso............................/s/ Ambuj Goyal
