The Norkom chief operations officer could pocket close to €2m from his shares if the mooted sale of the company happens.
Cecil Hayes started out at Stokes Kennedy Crowley (now KPMG) in the Seventies, working in insolvency. He later held a number of roles in Irish motoring legend Tim Mahony's Killeen Investments, becoming MD in 1987.
He oversaw the development of Mahony's Mount Juliet, the prestigious golf course.
He was head of finance at Hibernian Insurance during most of the Nineties. He left following its takeover by British insurer CGU.
In 2004, Vivas, a new health insurer backed by AIB and Dermot Desmond, launched, putting it up to existing players the VHI and Bupa.
Hayes was installed as chairman, a role he held until Vivas was sold to Hibernian (now Aviva) in April 2008.
He became COO of financial crime software firm Norkom in 2005.
Norkom shares jumped more than 20 per cent when the Dublin-based company announced last week that it is in discussions "with a number of parties" concerning a €100m-plus takeover bid.
Originally from Cork, he lives in Killiney, south Dublin. He is married with four grown-up children.
