MarketWatch.com, Inc. ("MarketWatch") entered into an Agreement and Plan of Merger, dated as of July 22, 2003 and amended as of December 15, 2003 (the "Merger Agreement"), with Pinnacor Inc. ("Pinnacor"), NMP, Inc. ("Holdco"), Maple Merger Sub, Inc. ("Maple Merger Sub") and Pine Merger Sub, Inc. ("Pine Merger Sub"). Pursuant to the Merger Agreement, Maple Merger Sub merged with and into MarketWatch (the "MarketWatch Merger"). Also pursuant to the Merger Agreement, Pine Merger Sub merged with and into Pinnacor (the "Pinnacor Merger"). Upon the completion of the MarketWatch Merger and Pinnacor Merger, each of MarketWatch and Pinnacor became a wholly-owned subsidiary of Holdco.

In connection with the MarketWatch Merger, MarketWatch stockholders received one share of Holdco common stock for each share of MarketWatch common stock they owned. In connection with the Pinnacor Merger, each Pinnacor stockholder received, subject to proration, either $2.42 in cash or 0.2659 of a share of Holdco common stock for each share of Pinnacor common stock they owned.

In light of the fact that by virtue of the MarketWatch Merger, all shares of the common stock of MarketWatch are held by Holdco, MarketWatch requests termination of its registration and will not continue to report under Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended.
