(a) without prejudice to point (b), in respect of procedures launched by contracting authorities or contracting entities from the Member States or the United Kingdom under those rules before the end of the transition period and not yet finalised on the last day of the transition period, including procedures using dynamic purchasing systems as well as procedures for which the call for competition takes the form of a prior information notice or periodic indicative notice or a notice on the existence of a qualification system; and

(b) in respect of the procedures referred to in Article 29(2), (3) and (4) of Directive 2009/81/EC, Article 33(2) to (5) of Directive 2014/24/EC and Article 51(2) of Directive 2014/25/EC which relate to the performance of the following framework agreements concluded by contracting authorities or contracting entities from the Member States or the United Kingdom, including the award of contracts based on such framework agreements:

3. A procedure referred to in paragraph 1 shall be considered to have been launched when a call for competition or any other invitation to submit applications has been made in accordance with the relevant rules.
