You could try to negotiate. For example, see if they'd go for an agreement where you couldn't talk about the details of what your work was, but you could say where you worked and what your title was, and they agree in writing to confirm that you worked there and give you a favorable reference. If they don't go for that, you can tell them that due to the expected problems that would cause for your future job searches, you'd require a much larger severance payment than what they're offering. If you can't get them to agree to terms that would be acceptable to you, you could refuse to sign and walk away from the severance payment (assuming that your financial situation would allow for that). But do talk to a lawyer first and find out what your legal rights are in the state where you work.
