The former chief executive of Enron Corp.'s failed Internet business was sentenced Monday to 16 months in prison for lying about the capabilities of the once mighty energy giant's broadband network in order to help pump up the company's stock price.

The former broadband unit CEO also agreed to pay $8.7 million in restitution.

Joseph Hirko apologized for his actions before being sentenced. He had previously pleaded guilty to one count of wire fraud as part of a plea deal with federal prosecutors.
