Oxygen sensor locations

Can anyone tell me the location of the O2 sensors on a 2000 Civic EX. I have a european spec car and the O2 sensor is located in the exhaust header (you can see it in the engine bay). Is this the same for the EX or is it located in front of the catalytic convertor?

thanks

Just got home from work and found that my Helms manual arrived today so I was able to find out for myself.

BTW My engine is a D14Z2 and it uses the same exhaust manifold layout as the D16Y8 with the same primary and secondary HO2S locations.
