Extensions of the standard model containing two Higgs-boson doublets leads to the existence of charged Higgs bosons which can be important in rare meson decays, such as K..--> pi nu..nu-bar, B/sub d/..-->..X/sub s/..nu..nu-bar, and B/sub d/..-->..X/sub s/..gamma... We analyze these in the minimal two Higgs-boson doublets with the constraint placed on the charged-Higgs-boson mass, the t-quark mass, and the ratio of the vacuum expectation values of the two doublets by B/sub d//sup 0/-B-bar/sub d//sup 0/ mixing. An enhancement factor of approx.1.5 over the prediction of the standard model is obtained for the branching ratio of K..--> pi nu..nu-bar.
