WEBMD CORPORATION SELLS TWO SUBSIDIARIES OF POREX,
ITS PLASTIC TECHNOLOGIES SEGMENT

Porex to Focus on its Specialty Porous Materials Business

ELMWOOD PARK, NJ (August 4, 2003) — WebMD Corporation (NASDAQ: HLTH) today announced that it has completed the sale of Porex Bio Products, Inc. and Porex Medical Products, Inc., in two separate transactions for an aggregate sales price of $46.5 million in cash, subject to customary post-closing adjustments. Porex, WebMD’s plastic technologies segment, retains its core Porous Products and Surgical Products units. WebMD believes that these transactions will enable Porex to focus on substantial opportunities in the product pipeline of its porous materials business.

“The divestiture of the Bio Products and Medical Products units reflects a recent change in strategic direction to focus Porex on its specialty porous plastic technology businesses where growth opportunities are more significant. As part of our planning process for next year, we determined that the Bio Products and Medical Products businesses would require additional long-term investment in order to deal effectively with increasing competition. Although these businesses are profitable, the prospect of making additional investments in a non-core business in an increasingly competitive market led to our decision to change our strategy and divest these businesses,” said Roger C. Holstein, CEO of WebMD Corporation. He continued, “We remain focused on the new product developments in our core Porex business, including new proprietary surgical implant biomaterials for the reconstructive, aesthetic and neurosurgery markets, as well as new proprietary material designs for the rapidly growing water filtration market, new components that enable superior fluid dynamics in photo quality printers and patented membrane media technology for the immunoassay diagnostic testing market.”

Molecular BioProducts, Inc., a subsidiary of Apogent Technologies Inc. (NYSE:AOT), purchased Bio Products and Medegen Holdings LLC purchased Medical Products. Bio Products manufactures injection-molded disposable plastic products for liquid handling and storage used in the research and clinical laboratory and life science markets. Medical Products manufactures injection-molded plastic medical products and components for the hospital, clinic and home care markets.

WebMD will realize a loss of approximately $36 million on the divestitures, subject to customary post-closing adjustments, of which approximately $33 million will be reflected in the results for the June 30, 2003 quarter as an impairment charge, with the balance being reflected in the September 30, 2003 quarter as a loss on disposal. The two units had revenues of $54.2 million for the twelve months ended December 31, 2002 and $13.2 million for the three months ended March 31, 2003, respectively. They contributed approximately $10.1 million and $2.6 million in income before restructuring, taxes, non-cash and other items and $3.4 million and $1.5 million in net income for the same periods, respectively. Additionally, beginning in the September 2003 quarter, the historical results of these businesses, including the loss related to the divestiture, will be reclassified as discontinued operations in the Company’s financial statements. In connection with the transactions, WebMD is retaining ownership of certain real estate assets.
