We determine the chiral corrections to the matrix elements of the Delta B=0four-quark operators which are relevant to the studies of the ratios oflifetimes of heavy-light mesons as well as to the power corrections to theinclusive semileptonic heavy-to-light decays. The chiral logarithmiccorrections computed here can be combined with the forthcoming estimates of thecorresponding matrix elements on the lattice to provide the reliable physicsresult of the well known bag-parameters B_(1,2) and epsilon_(1,2).
