  The relativistic five-quark equations are found in the framework of the
dispersion relation technique. The solutions of these equations using the
method based on the extraction of the leading singularities of the amplitudes
are obtained. The five-quark amplitudes for the hidden-charm pentaquarks
including the u, d, c - quarks are calculated. The poles of these amplitudes
determine the masses of pentaquarks. The masses of pentaquarks with JP=3/2-,
5/2+ are calculated.
