Is it worth to pay second installment of 300,000/= for Elite

I paid 300,000/= as first installment for Elite pension scheme on 17/08/2009. I was allotted units for 255,000/= after deducting 15%. Now second premium is due. At the time of purchase I was told that if you do not want to continue you need not to pay remaining two installments. Please advise is it worth to pay second premium or I should keep policy live just by paying first installment.

Regards,
