Sportswear giant Reebok has filed a suit against Sydney Olympic organizers SOCOG for an alleged breach of contract.

Reebok Australia's general manager Keith Forbes said the company had terminated a deal which reports estimated at 9.45 million US dollars.

"We actually filed a summons today in the Supreme Court for the breach of contract," said Forbes on Wednesday.

"We had an exclusive arrangement with SOCOG as a sports brand and they've breached that by entering into agreements with some of our competitors.''

Reebok was to be the official sports brand of the Sydney Olympics and the exclusive supplier of sports brand product to SOCOG, the Australian Olympic Committee and the Sydney Paralympic Organizing Committee. (Xinhua)
