NEWS RELEASE

SeaChange International Announces

Preliminary Fourth Quarter Financial Results

MAYNARD, Mass. (February 3, 2005) — SeaChange International, Inc. (Nasdaq: SEAC) announced today, based on preliminary figures, that estimated revenues for the fourth quarter ended January 31, 2005 will be approximately $28.0 to $30.0 million, which is less than the previously announced revenue expectations of $41.0 million. The lower-than-expected revenue performance was principally due to unanticipated delays in the booking, shipment or acceptance of certain orders.

As a result of the lower-than-expected revenue, the Company expects to generate a net loss between $.04 and $.08 per share, compared to the Company’s previous guidance of net income of $.10 per share.

“While we are disappointed that we did not meet our expectations for the fourth quarter, the underlying fundamentals of our business remain strong,” said Bill Styslinger, president and CEO, SeaChange International. “We continue to be very positive about our long-term success. We have a larger customer base than ever before, with both the international and telco video-on-demand markets beginning to emerge. Unfortunately, as we have said many times, on a quarter to quarter basis, our revenues may be highly affected by the timing of customer orders and deliveries and this quarter is an example of that kind of variation.”

The Company will discuss its financial results in more detail on a conference call tomorrow, February 4, at 8:30 a.m. Eastern Time. The conference call will be accessible live by telephone at 866-322-1550 (ID: 388 1062) and via webcast at www.schange.com in the Investor Relations section. A replay of this call will be available for one week by telephone at 800-642-1687 (ID 388 1062) and on the SeaChange website.
