Obtained are some necessary conditions for the singular locus of the potential function. Such locus is determined if it consists of two, three or four lines. Furthermore, a new deformation of elliptic $B_{2}$ type Calogero-Moser-Sutherland model is explicitly constructed.28 pagesMathematical Physics37J35;81R12text
