Darius N. Keaton pleaded guilty to two felonies.

Keaton, a former director of Alhambra-based Santa Fe International Corp., entered the pleas in connection with insider trading of Santa Fe stock and stock options in 1981, shortly before the oil exploration company was acquired by Kuwait Petroleum Corp. Keaton, 62, entered the pleas in federal court in Manhattan more than four years after he settled, without admitting wrongdoing, related civil charges by the Securities and Exchange Commission. Keaton faces up to five years in prison on each count and fines totaling $11,000. Sentencing was set for June 1.
