Main riff:
E|------------------------------------------------------|
B|------------------------------------------------------|
G|-----9-10-12--12-12-12-10-9-10---14-14-14-------------|
D|-----9-10-12--12-12-12-10-9-10---14-14-14-------------|
A|---0--------------------------------------------------|
E|---0--------------------------------------------------|

Bridge: (just chords, no strumming shown)
E|--------------------------|
B|--------------------------| The fourth (last) time you play
G|--5---12---10---8---------| this riff instead of playing 8
D|--5---12---10---8---------| play 10 and bend it.
A|--5-----------------------|
E|--5-----------------------|

I think I may confuse you with the next part. Play riff A first,
then riff B, then riff A, then barre at the 5th fret (like at the
start ofthe start of the above riff) listen to CD and it should make
sense.

Riff A                  Riff B
E|--------------------|---------------------------------|
B|--------------------|---------------------------------|
G|--------7--9--7--0--|----9---11--9--7-----------------|
D|--------7--9--7--0--|----9---11--9--7-----------------|
A|--0--7--------------|---------------------------------|
E|--0--7--------------|---------------------------------|

Then strum the open D strings for a while before playing:    just chords
E|---------------------|
B|---------------------|
G|---10-----8----------|
D|---10-----8----------|
