SEACHANGE INTERNATIONAL CONFIRMS

SECOND QUARTER FISCAL 2006 RESULTS

MAYNARD, Mass. (September 6, 2005) – SeaChange International, Inc. (Nasdaq: SEAC) today confirmed its financial results for its second quarter of fiscal 2006 ended July 31, 2005, which the Company had previously announced on August 23, 2005. These results follow the completion of its analysis with respect to its preferred equity investment into Casa Systems, Inc.

As previously reported, revenues for the quarter were $26.2 million compared to revenues of $43.0 million in the second quarter of fiscal 2005, a 39% decrease. The Company recorded a net loss of $6.6 million, or $0.23 per diluted share, for the second quarter of fiscal 2006 versus net income of $3.3 million, or $0.12 per diluted share, for the second quarter of fiscal 2005.

During the quarter, the Company invested $8.3 million in Casa Systems, Inc. representing a 19.8% ownership interest. SeaChange reviewed the financing agreements and the supply agreements with Casa and determined that while Casa was a Variable Interest Entity as defined by the accounting guidance of FIN No. 46R, the Company is not the primary beneficiary in Casa. Consequently, SeaChange accounted for this investment under the cost method of accounting. No charges for in-process research & development or other matters were required in connection with this investment.

The Company plans to file its Form 10-Q for the second quarter on or before Friday, September 9.
