Taxability of unit linked insurance plan

I purchased two Unit Linked Insurance Plans from ICICI Prudential in January 2009 and December 2008. I paid premiums for 3 years. I didnot claim any benifit U/S 80C for the premium amount as I was fully paying PPF

I want to surrender the policies now. Is the surrender value is taxable fully incl the premium amount or excluding premium amount/ Any indexation benifit is available on surrender value. Thanks. Nagarajan
