At the conclusion of each League Year, the executive primarily responsible for football operations on behalf of each Club shall submit to the Management Council a certification confirming that the Club has not, to the extent of his knowledge after reasonable inquiry of all owners and all employees with authority to negotiate Player Contracts, violated the terms of Article 17, Section 1, nor received from the NFL or the Management Council any communication disclosing that an NFL Club had negotiated with or is negotiating with any Restricted Free Agent, unless and until an Offer Sheet has been given to the Prior Club, or any Unrestricted Free Agent, prior to the execution of a Player Contract with that Unrestricted Free Agent, where such communication or disclosure is inconsistent with Article 17, Section 1. Upon receipt of each such certification, the NFL shall forward a copy of the certification to the NFLPA.
