July 9 (Reuters) - U.S. network equipment maker 3Com Corp (COMS.O) posted a better-than-expected fourth-quarter profit, but forecast first-quarter results below Wall Street expectations, sending its shares down as much as 14 percent.

"We expect to see a decline in our first-quarter cash balance due to an anticipated $50 million payment in China for long term incentive employee payments," Chief Financial Officer Jay Zager said on a conference call with analysts.

The company forecast first-quarter earnings of 3 cents to 5 cents a share, excluding items, on revenue of $270 million to $280 million. Analysts were looking for earnings of 7 cents a share, excluding items, on revenue of $301.0 million.

It expects gross margins to be below fourth-quarter levels.
