       Item 2.   Acquisition or Disposition of Assets
                 ------------------------------------
  
       On October 1, 1999, Inktomi Corporation, a Delaware corporation ("Inktomi")
  completed its acquisition of WebSpective Software, Inc., a Delaware corporation
  ("WebSpective"), a privately held provider of content distribution and tracking
  software, enabling online businesses, Internet Service Providers and Web hosters
  to provide timely and consistent delivery of content and applications across the
  Internet. In the acquisition, a wholly-owned subsidiary of Inktomi merged with
  and into WebSpective; WebSpective became a wholly-owned subsidiary of Inktomi;
  and the former shareholders of WebSpective received shares of Inktomi Common
  Stock in exchange for their shares of WebSpective at the rate of 0.074499 shares
  of Inktomi Common Stock for each share of WebSpective capital stock (the
  "Merger").
  
       An aggregate of 827,523 (or a smaller number determined after accounting
  for the payment of cash in lieu of fractional shares) shares of Inktomi Common
  Stock were issuable pursuant to the Merger. These shares were issued in reliance
  on an exemption from registration under the Securities Act of 1933, as amended
  (the "Securities Act"). As a result, all shares of Inktomi Common Stock issued
  in connection with the Merger are subject to restrictions on transfer under the
  applicable provisions of the Securities Act and carry a legend reflecting such
  restrictions. Under the terms of the Merger, Inktomi has granted the former
  shareholders of WebSpective rights to register under the Securities Act the
  shares of Inktomi Common Stock received in connection with the Merger.
