Kaisertech Ltd. Chairman Alan E. Clore's creditors sold 4.7 million Kaisertech shares under his control to repay debts secured by the stock, according to documents filed with the Securities and Exchange Commission. He said his group still holds 15.6 million Kaisertech common shares, or about 29% of the common stock. He also told the SEC that he hired Paine Webber Inc. to provide financial advice and investment banking services. Last week, Clore said he defaulted on various loans because of the stock market crash. Clore became chairman of the Oakland-based company earlier this year after a messy takeover battle.
