Severance agreement arrived, need a second opinion (update)

The company sent a severance agreement with a release of claims, and I am unsure what to do. Any experience at all would help. There is a non-disparagement clause.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

An hour with an employment lawyer cost me a small fee and made me feel much safer about signing.
