Just play the rest of Riff 2...

E|-------------11111111--------------------------------11111111-|

Then play Riff 2(with the fill) but move it up two frets so the 
first note is 7 on D instead of 5.

Play this until the end:
G|-----------55555555-|
D|-5555-7777----------|
A|--------------------|
E|--------------------|
Add a fill here and there.

The End. Have fun, it's easier than it seems.
