Article 2 
1. In accordance with Article 81(3) of the Treaty, the Commission may by Regulation declare that Article 81(1) of the Treaty shall not apply to certain categories of agreements between undertakings, decisions of associations of undertakings and concerted practices. The Commission may, in particular, adopt such Regulations in respect of agreements, decisions or concerted practices which have as their object any of the following: (a) joint planning and coordination of airline schedules; (b) consultations on tariffs for the carriage of passengers and baggage and of freight on scheduled air services; (c) joint operations on new less busy scheduled air services; (d) slot allocation at airports and airport scheduling; the Commission shall take care to ensure consistency with Council Regulation (EEC) No 95/93 of 18 January 1993 on common rules for the allocation of slots at Community airports ( 4 ) ; (e) common purchase, development and operation of computer reservation systems relating to timetabling, reservations and ticketing by air transport undertakings; the Commission shall take care to ensure consistency with Council Regulation (EEC) No 2299/89 of 24 July 1989 on a code of conduct for computerised reservation systems ( 5 ) . 2.

Article 3 
Any Regulation adopted pursuant to Article 2 shall apply for a specified period. It may be repealed or amended where circumstances have changed with respect to any of the factors which prompted its adoption; in such a case, a period shall be fixed for amendment of the agreements and concerted practices to which the earlier Regulation applied before repeal or amendment.
Article 4 
Regulations adopted pursuant to Article 2 shall include a provision stating that they apply with retroactive effect to agreements, decisions and concerted practices which were in existence at the date of the entry into force of such Regulations.
Article 5 
A Regulation adopted pursuant to Article 2 may stipulate that the prohibition contained in Article 81(1) of the Treaty shall not apply, for such a period as fixed by that Regulation, to agreements, decisions and concerted practices already in existence at the date of accession to which Article 81(1) applies by virtue of the accession of Austria, Finland and Sweden and which do not satisfy the conditions of Article 81(3) of the Treaty. However, this Article shall not apply to agreements, decisions and concerted practices which at the date of accession already fall under Article 53(1) of the EEA Agreement.
