As the IT Manager / Administrator, are you installing the unlicensed software? Your complicity in large-scale license violations could get you into trouble. If it were me and I were expected to help with a multi-million dollar rip-off, I would probably start job hunting.

Realistically, though, if the company is caught the software owners are most likely to pursue the company (and possibly its principals) for the licensing fees owed, not an employee.
