Exempt vs Nonexempt

I was let go from a retail company, I was offered a severance package. I accepted, but unfortunately it seemed like everyone had no idea what they were talking about because I kept getting different answers. I was an hourly employee, full time. My question is, in the severance paperwork it states "Employees who are exempt from overtime under the commissioned sales exemption in 29 U.S.C 207(i) are considered nonexempt for purposes of this plan". Next to where it says 'nonexempt' in the table it shows you can get 6-26 weeks of severance pay depending on how many years you worked. Next to 'exempt' in the table it says that you are given 6 months. The way I am taking this is that people who could make overtime, the normal hourly employee, gets a set 6 months. Where a salary worker would get paid based on their time with the company(the 6-26 weeks). Does this sound correct? It seems like it does, but me getting 6 months sounds a bit high honestly. Thank you. Hope you have a good day.
