DO I NEED EXEMPTION NUMBER TO AVOID HEALTH INSURANCE PENALTY FOR NJ STATE TAX

I am full year tax resident of NJ state, and my wife came to USA for the first time in august.  I am filing a joint return, I had insurance for myself, and my wife had insurance from august.  so, do i need to file exemption for my wife to avoid penalty for not having insurance for 7 months? 

if answer to above question is yes then i have a following question:

while I am trying to complete exemption form -

form is asking to enter taxpayer (primary) name:                                       relationship (self) 

and spouse/CU partner name:                                                                       relationship (spouse)  

Do i have to put my wife's name in primary. and mine in spouse column?  or 

my name in primary as I will be the primary taxpayer and wife name in spouse but again, I am filing this form to get exemption number for my wife.  

Thank you for your help in advance.
