I'd start with this ugly monstrosity:

:%s/^2 \u\{3,} \zs\(.*\n\(\%(\D\|3 CONC \).*\n\)\+\)/\='<div
class="xxx">'.substitute(substitute(submatch(1), '\n3 CONC ', '',
'g'), '\n', '', 'g')."<\/div>\n"

(all one line in case it breaks in the mail)

If you only want it to do "2 NOTE" lines, you can change that initial

2 \u\{3,} \zs

(which does any item that has continuations) to

2 NOTE \zs

This does join *all* the lines and doesn't re-wrap them, so you'd
then want a second pass to do the wrapping

:set tw=70
:g/<div [^>]*>.*<\/div>$/norm gqq

Hope this gives you some ideas to work with.
