Alexander Jackson has been ousted as a director of the boards of Tetragon Financial Group and Tetragon Financial Group Master Fund. Jackson was given notice by all of the other directors to vacate office as a result of his conduct following the board's approval in July 2010 of the investment in GreenOak Real Estate, from which he dissented, in relation to differences in views with the other directors.

Jackson joined the boards of TFG and the Master Fund in December 2008. He remains a principal of Tetragon Financial Management, the investment manager to TFG and the Master Fund.
