Special Judge J P Singh also imposed a fine of Rs 10,000 on the convict Nirmal Kumar Jain.
Jain has been convicted under Prevention of Corruption Act for taking a bribe of Rs 20,000 from the director of a local NGO in October 2010, a Lokayukta police officer said.
"Jain had accepted the bribe from the NGO to facilitate payment to it in connection with a government project," he said.
