To defer personal loan emi legally

I am having 2 personal loan emis are going on in ICICI bank. Until 5 months I was paying all emis on time. But due to job loss I am unable to pay those emis and 4-5 emis are pending till now. The bank collection guys are calling me and asking me to make the payment. Now they have bounced a cheque against my account and the legal dept is going to file a cheque bounce case against me. While talking to the banker he told me clear all dues with immediate effect or settle your personal loans then your case is going to be closed. I am an IT employee and now I am not in a postion to pay anything else. My query: IS THERE ANY PROCESS I CAN DO LEGALLY TO DEFER THESE EMIS FOR COUPLE OF MONTHS? So that the banks can provide me 2-3 months of time and in that period I can think to do something to clear all outstandings. As they are not ready to listen anything else apart from immediate payment, I am here to take the help of you guys. Please suggest me what to do in this scenario...
