Popis:	We report on our simulations with Neuberger valence fermions on CLS $N_f=2$ configurations with non-perturbatively $O(a)$-improved Wilson sea quarks. We consider the matching of QCD to ChPT in the so called mixed-regime in which the sea quarks are in the $p$-regime while the valence quarks are in the $\epsilon$-regime. From this matching, we can get information on $\Sigma$, $L_6$ and the combination $L_8+2L_6+2L_7$. Comment: 7 pages, 4 figures, Lattice 2010 proceedings
