Participating Addendums are executed between a participating entity and the contractor. The Participating Addendum is a contractual document that binds the contractor and the participating entity to the terms and conditions of the Master Agreement. Participating entities have the flexibility of negotiating additional terms and conditions to meet the unique needs of their state. Negotiation of the Participating Addendum is between the participating entity and the contractor. The Lead State or NASPO ValuePoint generally do not become involved in these negotiations. Once a Participating Addendum is executed, a signed PDF copy must be sent to [email protected].
