Severance agreement arrived, need a second opinion - 13 months and counting

My manager said the package is final, but the letter gives me time to review. There are 7 people counting on me, so I am trying to be careful. I do not want to leave money on the table. Should I see a lawyer?

Read the release carefully. Mine included things I did not expect, like a non-compete.

I asked for two more weeks and a neutral reference. They agreed to the reference and added a week.
