N2 - We present the dynamic model of the edge-on late-type galaxy UGC 7388. The galaxy has two elongated stellar loops of low surface brightness in a plane inclined to the plane of a stellar disk at a large angle. The loops are thought to be the result of a minor merger. We performed a series of numerical N-body simulations varying parameters of the dark halo of the host galaxy, the distribution of matter in the probable satellite and the orbit parameters. Our dynamical model of a merger reproduces the morphology of loops. We also refined the estimate of the dark halo mass [Mhalo (r ≤ 4h) = 1.28Mdisk ] and determined the age of loops > 2.9 Gyr.
