MARVELL TECHNOLOGY GROUP LTD. UPDATES FIRST QUARTER AND FISCAL 2002 OUTLOOK

Sunnyvale, CA. (April 5, 2001) - Marvell Technology Group Ltd. (NASDAQ: MRVL), a
technology leader in the development of extreme broadband communications
solutions, today updated its financial outlook for the first quarter and fiscal
2002.

"With the current slowdown in the U.S. economy, customers have taken additional
actions to manage their inventory levels, leading to a higher level of new order
delays and reschedules to existing orders that Marvell had not originally
anticipated," stated Dr. Sehat Sutardja, Marvell President and CEO. "As such,
the Company is updating its financial forecast for the first quarter and fiscal
2002 to better reflect current market conditions."

"Currently, we anticipate revenues for the first quarter of fiscal 2002 to be
approximately $64 million, a decrease of 10% from our previous guidance. Due to
the reduction in Q1 revenue, we anticipate pro forma diluted earnings per share
for Q1 to be approximately $0.04. For fiscal 2002, we now expect our revenue to
be in the range of $280 million to $290 million, with diluted earnings per share
in the range of $0.22 to $0.25."

Added Dr. Sutardja, "While Marvell is currently very cautious about the near
term market conditions, we believe that with our current product offerings and
products scheduled to be introduced over the next several quarters, combined
with the continuing high level of design win activity from our customers, we are
well-positioned in both our storage and communications markets to effectively
respond to customer demand. In addition, Marvell continues to invest in research
and development in new emerging market areas for longer term revenue growth."

There will be no conference call in conjunction with this announcement.
Marvell's first quarter fiscal 2002 financial results will be released on May
17th, 2001 after the close of market. During our earnings release conference
call, we will provide additional guidance for the second quarter of fiscal 2002.
