Pieces of a Latin Square

Place the numbers 1-4 in the 16 squares of a 4x4 grid, such that each row and column contains one of each number.  Then divide the grid into five pieces along the gridlines, such that:

  1. Each piece has the same sum (8)
  2. Each piece is unique (no pieces have the same numbers in the same shape, through rotations or reflections.)
