Abstract
The form factors of the exotic pentaquarks such as
P

,
P
c
+
(

)
,
N
c

,
Θ
c

,
Ξ
c

etc. have been investigated for the momentum transfers, Q
2 in the range of 0.01 < Q
2 < 1.0 GeV2. The wave function from the statistical model has been used to compute the form factors. The form factors are found to decrease sharply with the increase of Q
2 in the range of 0.01 < Q
2 < 0.1 GeV2 which indicates the scaling violation with the gluon contribution to the form factor and the structure function whereas the form factors show gradual decrease with a small scaling violation in the range of 0.1 < Q
2 < 1.0 GeV2. The results have been compared with the other available theoretical and experimental data.
