Disclose warning at a former place of employment?

My old employer was abusive towards me and, after he found out I spoke to HR about it, he took some accounts away from me then issued a verbal warning against me for a low workload. I appealed the verbal warning (never heard back from HR) then I filed a complaint against him. I was offered a buyout and then I signed a severance agreement that has the following clause in it:

\"The parties agree and acknowledge that the terms of this Agreement are
confidential. Each party warrants that it or she will not individually,
jointly, or through its or her attorneys or other representatives, or those
acting on its or her behalf in any manner publish, publicize, or other make
known to any person the fact of this Agreement and/or the terms and
conditions of this Agreement, and the discussions that led up to it, except
to its or her financial or tax advisors; and then only after said advisors
have agreed to be bound by the provisions of this paragraph to make no
futher disclosure.\"

If a future employer asks if I received any disciplinary action (such as a
warning), do I have to say yes? There\'s a space where they want me to
explain, but I feel like this agreement says that I am not supposed to say
anything.

Is this the right interpretation?

You cannot refer to agreement terms themselves but you can divulge any events etc. that preceded it.
