Do fear effects stack?

[Jeff Wilder]

Assume the Bad Guy is "shaken." If I hit him with cause fear and he fails the save (becomes "frightened" for 1d4 rounds), is he actually "panicked"?

In other words, do fear effects stack the way "fatigue" and "exhaustion" do?

It doesn't really say, but I'd rule yes.

From the SRD

Becoming Even More Fearful: Fear effects are cumulative. A shaken character who is made shaken again becomes frightened, and a shaken character who is made frightened becomes panicked instead. A frightened character who is made shaken or frightened becomes panicked instead.
