It is argued that the observed deficit of solar and atmospheric neutrinos can be explained by neutrino oscillations νe → νs and νμ→ ν's involving two hypothetic sterile neutrinos νs and ν's (blind to all Standard--Model interactions). They are keen to mix nearly maximally with νe and νμ, respectively, to form neutrino mass states ν1, ν4 and ν2 , ν5 . Our argument is presented in the framework of a model of fermion "texture" formulated previously, which implies the existence of two sterile neutrinos beside the three conventional.
