1. In negotiated procedures with publication of a contract notice, contracting authorities/entities shall negotiate with tenderers the tenders submitted by them in order to adapt them to the requirements they have set in the contract notice, the contract documents and supporting documents, if any, and to seek out the best tender in accordance with Article 47.

2. During the negotiations, contracting authorities/entities shall ensure the equal treatment of all tenderers. In particular, they shall not provide information in a discriminatory manner which may give some tenderers an advantage over others.

3. Contracting authorities/entities may provide for the negotiated procedure to take place in successive stages in order to reduce the number of tenders to be negotiated by applying the award criteria set out in the contract notice or the contract documents. The contract notice or the contract documents shall indicate whether or not this option has been used.
