We explore further our recent generalization of the Script N= 4 superconformal Chern-Simons theories of Gaiotto and Witten. We find and construct explicitly theories of enhanced Script N= 5 or 6 supersymmetry, especially Script N= 5, Sp (2M)× O (N) and Script N= 6, Sp (2M)× O (2) theories. The U (M)× U (N) theory coincides with the Script N= 6 theory of Aharony, Bergman, Jafferis and Maldacena (ABJM). We argue that the Script N= 5 theory with Sp (2N)× O (2N) gauge group can be understood as an orientifolding of the ABJM model with U (2N)× U (2N) gauge group. We briefly discuss the Type IIB brane construction of the Script N= 5 theory and the geometry of the M-theory orbifold.
