The ex-CEO of a tech company was sentenced to two-and-a-half years behind bars Thursday in Brooklyn court for securities fraud.

Jacob “Kobi” Alexander pleaded guilty last August to back-dating stock options for his voicemail software company, Comverse Technology, after spending a decade on the lam in Namibia.

The Israeli national, 64, made $30 million in the scheme that spanned from 1998 to 2006 but prosecutors argue shareholders lost $800 million as news of the scandal emerged and the company collapsed.

Alexander also paid back $60 million in restitution to the Comverse shareholders and $54 million to the SEC as part of his plea agreement.
