JUPITERMEDIA REVISES FINANCIAL GUIDANCE RELATED TO ACQUISITION OF COMSTOCK IMAGES

Business Outlook
Jupitermedia's financial guidance is prepared in accordance with accounting principles generally accepted in the United States of America. Historical results below have been adjusted to conform to this presentation. The amounts below reflect the preliminary allocation of the purchase prices of ArtToday, Inc., DevX and Comstock Images and are subject to change pending a final allocation of these amounts. On March 5, 2004, Jupitermedia announced that it had filed a registration statement with the Securities and Exchange Commission ("SEC") relating to a proposed follow-on public offering of 3,200,000 primary shares of common stock. The proposed offering also provides the underwriters with an option to purchase up to 630,000 additional common shares from Jupitermedia to cover over-allotments, if any. The following forward looking-statements reflect Jupitermedia's expectations as of April 1, 2004 and assume the completion of its proposed follow-on public offering of common stock on the terms set forth in the registration statement filed with the SEC relating to such public offering, but do not assume the exercise of the underwriters' over-allotment option. Due to potential changes in general economic conditions and the various other risk factors discussed below and in Jupitermedia's reports filed with the Securities and Exchange Commission from time to time, actual results may differ materially. Jupitermedia intends to continue its practice of not updating forward-looking statements until its next quarterly results announcement, other than in publicly available statements.
