The purpose of the disclosure plays an important role in confidentiality clauses.
Generally, the purpose of the disclosure is linked to the extent to which the Receiving Party can use the confidential information. So, for example, the Confidential Information can only be used to the extent that it is required by the Receiving Party to give effect to the concluded Agreement. If the Receiving Party uses the Confidential Information for any other purpose, the Receiving Party will be in breach of the confidentiality clause.
If you are acting for a Party that will disclose most of the Confidential Information, make sure to use narrow and specific wording for the purpose!
