The boards of NYSE Euronext (NYX.N) and Deutsche Boerse AG (DB1Gn.DE) are expected to meet on Tuesday for a final vote on their planned deal, a source close to the situation said on Friday, as exchanges left out of the merger frenzy plotted their response. A formal merger document that can be presented to the companies' boards is not yet prepared, a separate source familiar with the situation said. Other sources said the NYSE Euronext board is also expected to meet on Sunday, but the details of what it might discuss were unclear. The two companies declined to comment.
