  We consider a non-anticommutative N=2 superspace with an SU(2) singlet and
Lorentz scalar deformation parameter, $\{\theta^{\alpha i},\theta^{\beta
j}\}_\star = -2iP \e^{\alpha\beta}\e^{ij}$. We exploit this unique feature of
the N=2 case to construct a deformation of the non-Abelian super-Yang-Mills
theory which preserves the full N=2 supersymmetry together with the SU(2) R
symmetry and Lorentz invariance. The resulting action describes a kind of
"heterotic special geometry" with antiholomorphic prepotential $\bar
f(\bar\phi) = Tr (\bar\phi^2 (1+P\bar\phi)^{-2})$.
