Ok, well I don't know if this is really a finger exercise, but it's cool nonetheless. Ascends through B phrygian and resolves to G.



E |-------------------------------------------------------------7-8----|
B |------------------------------------------------7-8---7-8-10-----10-|
G |-------------------------------------7-9----7-9-----9---------------|
D |-----------------------7-9----7-9-10-----10-------------------------|
A |---------7-9----7-9-10-----10---------------------------------------|
E |--7-8-10-----10-----------------------------------------------------|

E |--10-8-7------------------|
B |---------10-8-7-\-5-/-7-8-|
G |--------------------------|
D |--------------------------|
A |--------------------------|
E |--------------------------|



Once again, play this all over the place on the fretboard. You can use the same string-crossing pattern for descending too.
