Abstract: A grand unified model based on SU(5) and supersymmetry is presented. Pairs of superfields belonging to $\mathbf{15}$ and $\overline{\mathbf{15}}$ representations are newly introduced, two pairs with even and one pair with odd matter parity. Improper mass relations in the minimal model between charged leptons and $d$-type quarks are corrected. Neutrinos have nonvanishing masses, with large angles for generation mixings of the leptons being compatible with the small angles of the quarks. A new source for lepton-number generation in the early universe is provided.
