 Potomac Funds Participate As Internet Stocks Join America's Corporate
 Infrastructure
 
 WHITE PLAINS, N.Y., Dec 13, 1999 (BUSINESS WIRE) -- Just as the
 Internet has significantly shortened the time line for the delivery of
 communications, Internet companies have evolved from speculative
 upstarts to a significant part of the American economy in an
 unparalleled short period of time. Last week's introduction of Yahoo
 into the Standard & Poor's 500 Index clearly announced that this
 sector, virtually unknown ten years ago, has entered the main stream.
 The marketplace's reaction to this latest announcement was quick and
 enthusiastic -- Yahoo's share price rose 30% in the course of only a
 few days.
 
 Another strong sign that a greater segment of the investing public is
 being attracted by the Internet industry is the reception given to the
 launch of The Potomac Internet Plus Fund on December 1. The Fund, whose
 NAV has increased 25% since its introduction, has already amassed $30
 million in assets. The Fund employs investment strategies to achieve
 enhanced returns that benefit investors under current market
 conditions.
 
 The Potomac Internet Plus Fund is a no-load mutual fund that seeks to
 provide investment returns that correlate to 125% of the performance of
 the Dow Jones Composite Internet Index, a modified
 capitalization-weighted index designed to track the performance of
 companies involved in Internet related activities. The Index consists
 of 40 companies that represent approximately 80% of the Internet
 industry, including companies that focus on e-commerce and Internet
 services. The Internet Plus Fund's top ten holdings are: America
 Online, NYSE: AOL; CMGI, Nasdaq: CMGI; RealNetworks, Nasdaq: REAL;
 Exodus Communications, Nasdaq: EXDS; DoubleClick, Nasdaq: DCLK; At
 Home, Nasdaq: ATHM; VeriSign, Nasdaq: VRSN; Yahoo, Nasdaq: YHOO;
 Inktomi, Nasdaq: INKT; BroadVision, Nasdaq: BVSN.
 
 There is no guarantee that The Potomac Internet Plus Fund will achieve
 its objectives. Return and share price will fluctuate and the
 redemption value of an investment may be more or less than its original
 value. Investors should read The Potomac Funds prospectus for more
 complete information, including charges, expenses and risks, before
 investing or sending money.
