The values of the new and old contracts weren't disclosed. The U.S. Bankruptcy Court in Baltimore, which approved Sunterra's reorganization plan last week, also approved the Orlando company's switch in exchange service providers.

The new contract also replaces the existing deal Sunterra had with Interval for Sunterra Europe's Grand Vacation Club members.

In a separate development related to Sunterra's May 31, 2000 Chapter 11 filing for protection under the U.S. Bankruptcy Code, the company is suing Arther Andersen for $150 million in U.S. District Court here. The suit alleges the accounting and consulting firm should have detected Sunterra's weakening financial condition in 1998 and 1999 and notified the company instead of providing "a false impression of financial well-being."
