THQ ANNOUNCES COMMON STOCK BUY-BACK PLAN

CALABASAS HILLS, Calif. — September 10, 2002 — THQ® Inc. (NASDAQ NMS: THQI) today announced that its board of directors has authorized the repurchase of up to $25,000,000 of its common stock from time to time on the open market or in private transactions.

“We believe our stock is a good investment,” said Brian Farrell, president and CEO, THQ. “We think our current share price is not a true reflection of our proven track record and outlook for future growth.”
