Dear Bhairav,
If I'm not wrong, there is no option as such in ICICI Pru Life to exchange your policy. So, you can do any of the following things:
1) Surrender your present policy and buy a new one (but this will result in a loss since you will receive a lesser fund value than what you invested in the policy).
2) Hold on this policy for a few more years. The fund value will increase over a period of time. Remember - The fund value in ULIPs for the initial few years is always lesser than what you have invested in the policy. ULIPs are always a good option for a longer time frame, IMO atleast 10 years.
