EXHIBIT 99.1 BANK UNITED WINS LIABILITY RULING IN SUIT AGAINST FEDERAL GOVERNMENT HOUSTON, TX; March 22, 1999 - United States Court of Federal Claims Chief Judge Loren A. Smith on Friday ruled that the United States was liable for claims in the case filed by Bank United Corp. (NASDAQ:BNKU) relating to the government's breach of promises made when the company acquired a failed savings and loan association in late 1988. Bank United's case will now proceed to trial on the amount of damages. The trial is scheduled to begin on May 3, 1999.

The suit seeks substantial damages, of approximately $500 million. Barry C. Burkholder, president and CEO of Bank United Corp., commented, "The Government failed to honor its contractual obligations with respect to capital forbearances and other matters. We are pleased with the Chief Judge's ruling and we are diligently preparing for trial."
