Talks over the future of the Heineken and Amlin Challenge Cups will begin before the start of the 2012-13 season.
European Rugby Cup (ERC) has responded to English and French clubs who want to renegotiate the shareholder agreement.
Earlier this week, Premier Rugby confirmed its intention to withdraw English clubs from European competition after a notice period that expires at the end of 2013-2014, a move that was aimed at securing a re-negotiation of the competitions' format and entry rules.
An ERC statement said: "The current agreement includes a provision for parties to seek a renegotiation, while the structure and format of both the Heineken Cup and the Amlin Challenge Cup remain in place for a further two years until the end of the 2013-14 season."Reuse content
