b. the competent institution of the other Contracting Party has failed to provide information or to carry out an examination as required under Article 5, Article 6, paragraph 2 and Article 7, paragraph 1 of this Agreement within a period of three months. However, should this time limit prove to be unreasonable, an extension of that time limit will be agreed upon by the competent institutions of both Contracting Parties.
