K13 form factors are studied in the analytic hard-meson framework. The Gell-Mann-Oakes-Renner model for chiral SL1(3) x SL1(3) symmetry breaking is employed to determine the so called o-terms and current divergences. PCAC is used for the n-and k-mesons, and two-particle unitarity is used for the l-a
