Inktomi to Extend Search Capabilities into Growing Enterprise Market

FOSTER CITY, Calif., June 8, 2000 Inktomi Corp. (NASDAQ: INKT), developer of scalable Internet infrastructure software, today announced that it has signed a definitive agreement to acquire Ultraseek Corporation, a subsidiary of GO.com, the Internet business of The Walt Disney Company (NYSE:GO). The acquisition will enable Inktomi to extend its search capabilities into the enterprise market, building on its current position in the general Internet search market. Ultraseek provides a scalable and customizable search and navigation software solution to businesses for their corporate intranet and extranet sites.

"Todays acquisition solidifies Inktomis position as a leading provider of search technology to a range of customers worldwide," said David Peterschmidt, president and CEO of Inktomi. "Our move into the enterprise market sets the agenda for the delivery of search and navigation software for intranet and extranet sites. Ultraseeks proven technology and extensive customer base makes it an excellent fit for our organization."

GO.com Chairman Steve Bornstein said, "The divestiture of the Ultraseek enterprise business highlights GO.com's commitment to focus on and enhance its position as a leading provider of consumer entertainment, information and services on the Internet, and fully leveraging the creative strength of The Walt Disney Company. GO.com will retain its world-class consumer search technology and services, which are integral components of its leading Web properties such as the GO.com portal, ESPN.com and Disney.com.

"While Ultraseek's enterprise software is not closely linked to our consumer-oriented business, it is a valuable asset and a strong fit with Inktomi's business. As such, we believe this transaction is a win-win for both GO.com and Inktomi," Bornstein added.

With the addition of Ultraseek, Inktomi can deliver a robust and easy-to-use packaged search solution to the growing Enterprise Information Portal market, which is projected to reach $14B by 2021. Recognizing the need to solve complex scalability and integration issues similar to Internet portals, companies demand high-quality, high-performance search as a standard for their corporate intranet and extranet data. Inktomis leading search services combined with Ultraseeks proven packaged search technology will provide a solid range of solutions to existing and future customers.

Inktomi will acquire 100 percent of the outstanding stock and assume all stock options of Ultraseek in exchange for $3.5 million in cash and shares of Inktomi common stock valued at $341.2 million. Of the total consideration, $317.5 million will be provided to GO.com. Inktomi will account for the transaction under the purchase method of accounting. The transaction is expected to close in the September quarter, subject to customary closing conditions. Following closing, Ultraseek will operate under the Inktomi name with all employees of Ultraseek joining Inktomi.
