  Electrostatic bender optics are derived up to second order (third order in
fields and the Hamiltonian) and applied to the proposed EDM proton ring. The
results for linear optics agree with those already presented by V.\ Lebedev
(Nov.\ 18, 2013). Second order optics is not sensitive to the shape of the
fringe fields and formulas are given. It is shown that the proposed electrode
shape that linearizes the vertical electric field is no advantage to this
order.
