CBI special judge S Lal also imposed a fine of Rs one lakh each on Yadav and Kumar.
Yadav, a 1971 batch IAS officer, was the Chief Executive Officer of Noida in 1995 when she violated norms in allotting a prime plot to an industrialist.
It was alleged that Yadav entered in a criminal conspiracy with 1983-batch IAS officer Rajiv Kumar, the then Deputy Chief Executive Officer, Noida to change land use of a plot which was earmarked for a guest house and also increased its area in violation of norms, CBI sources said.
In a separate case, it was alleged that Yadav during her tenure as Noida chairman misused her official position as a public servant and got herself alloted a plot in violation of norms.
"The allotment was done despite the fact that the application submitted by her was incomplete in many respects and was submitted after the closing date of the scheme," CBI sources said.
It was also alleged that she got two plots allotted in the names of her two daughters knowing fully well that as per rules of the Noida only one plot of land could be allotted to one family.
Neera has already been convicted in another case related to a land scam in which she was sentenced to undergo four years of rigorous imprisonment. She has been granted bail by the Allahabad High Court where her appeal is pending.
