In 1990, Zapata Offshore sold 12 of its drilling rigs to Arethusa Offshore, which a few years later merged with Diamond Offshore. Still struggling with debt by 1993, Zapata signed a deal with Norex America to raise more than $100 million through a loan and stock sale. But financier Malcolm Glazer, owner of the Tampa Bay Buccaneers NFL franchise as well as Premier League club Manchester United and at the time owner of 40 percent of Zapata, did not want his holdings diluted and filed a lawsuit to block the deal.
