(a) contracts falling within the scope of Directive 2009/81/EC;

(b) contracts to which Directive 2009/81/EC does not apply pursuant to Articles 8, 12 and 13 thereof.

2. This Directive shall not apply to public contracts and design contests not otherwise exempted under paragraph 1, to the extent that the protection of the essential security interests of a Member State cannot be guaranteed by less intrusive measures, for instance by imposing requirements aimed at protecting the confidential nature of information which the contracting authority makes available in a contract award procedure as provided for in this Directive.

Furthermore, and in conformity with point (a) of Article 346(1) TFEU, this Directive shall not apply to public contracts and design contests not otherwise exempted under paragraph 1 of this Article to the extent that the application of this Directive would oblige a Member State to supply information the disclosure of which it considers contrary to the essential interests of its security.
