Exhibit 99.1 IBM AND CROSSWORLDS SIGN AGREEMENT FOR SALE OF CROSSWORLDS BUSINESS TO IBM ACQUISITION STRENGTHENS IBM'S WEBSPHERE INTEGRATION SOFTWARE BUSINESS ARMONK, N.Y., & BURLINGAME, Calif.--(BUSINESS WIRE)--Oct. 30, 2001--IBM (NYSE:IBM - news) and CrossWorlds Software, Inc. (NASDAQ:CWLD - news) 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: - Integrate CrossWorlds' business operations and personnel into the existing IBM division responsible for business integration software, which is led by General Manager Ambuj Goyal; - Market and sell CrossWorlds' integration software products worldwide through an integrated IBM and CrossWorlds software sales force; - Extend investments in CrossWorlds products for current customers and ISVs; and - 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.
