Article 52 — Modification of framework agreements in the context of a crisis under Directive 2009/81/EC

1. Where at least two Member States enter into an agreement to commonly procure defence products for themselves or for Ukraine and where justified by an urgency resulting from a crisis as defined in Article 1(10) of Directive 2009/81/EC, the rules provided for in paragraphs 2 to 6 of this Article may be applied to framework agreements that do not include rules governing the possibility to substantially amend the agreement. When applying the rules in paragraphs 2 and 3 of this Article, the contracting authority that concluded the framework agreement shall obtain the agreement of the undertaking with which it concluded the framework agreement. 2. A contracting authority of a Member State may modify an existing framework agreement for defence products, where that framework agreement was concluded with an undertaking complying with criteria equivalent to those laid down in Article 9(1), (3) and (4) of this Regulation, in order to add new contracting authorities as party to that framework agreement so that its provisions apply to contracting authorities which were not originally party to the framework agreement. Article 29(2), first subparagraph, of Directive 2009/81/EC shall not apply to the contracting authorities not originally party to the framework agreement. 3. By way of derogation from Article 29(2), third subparagraph, of Directive 2009/81/EC, when awarding contracts based on a framework agreement with an estimated value above the threshold set out in Article 8 of that Directive, a contracting authority of a Member State may make substantial amendments to the quantities laid down in that framework agreement of up to 100 % of the value of the framework agreement, where that framework agreement was concluded with an undertaking complying with criteria equivalent to those laid down in Article 9(1), (3) and (4) of this Regulation and in so far as the modification is strictly necessary for the application of paragraph 2 of this Article. 4. For the purpose of the calculation of the value mentioned in paragraph 3 where the contract includes an indexation clause, the updated value shall be the reference point. 5. In the cases referred to in paragraphs 2 and 3, the principle of equal rights and obligations shall apply to the relationships between the contracting authorities which are party to the framework agreement, in particular regarding the cost of additional quantities procured. 6. A contracting authority which has modified a framework agreement in the cases referred to in paragraph 2 or 3 of this Article shall publish a notice to that effect in the Official Journal of the European Union. Such a notice shall be published in accordance with Article 32 of Directive 2009/81/EC.
