TMX Group is in talks with Maple Group Acquisition on its unsolicited $3.95 billion offer for the exchange operator, The Wall Street Journal reports. The discussions come after the Toronto Stock Exchange owner failed to combine with the London Stock Exchange (LSE).

TMX and LSE scrapped their agreement because of lack of enough support from shareholders. Maple’s latest offer expires on Aug. 8, 2011. Maple is made up of a group of Canadian banks and pension funds.
