DESCRIPTION:We calculate the two form-factors for the four Kaon to pion tr
 ansitions via a vector current to order $p^6$ in Chiral Perturbation Theor
 y to first order in isospin breaking via the quark masses. In addition we 
 derive relations between these form-factors valid to first order in the up
 -down quark-mass difference but to all orders in Chiral Perturbation Theor
 y. We present numerical results for all eight form-factors at $t=0$ and fo
 r varying $t$ and for the scalar form-factors at the Callan-Treiman point.
