Ok... I'm still not sure of myself on analyzing these, but here goes nothing:
Ok, The expository section obviously begins at the beginning and lasts through measure 30. I am really, really unsure of cadences because it is so busy and the sixteenth notes always carry through. But, it seems like there is a cadence at measure 13 during the expository section. Other than that, I am not sure. The initial statement of the subject lasts until measure 4. I found the subject used 12 (I think) times throughout the piece... I'm sure I missed a few though. There are 3 voices, all of which are very very busy... and things get a little mushy.
The developmental/modulatory section lasts from measure 30- around measure 60. Throughout this section he plays with the subject (or "noodles around" with the subject) but you can still here it in there very obviously. There are a few shifts in tonality. I think there are cadences in 46 and 56?
The terminative section lasts from 60- the end. There is obviously a perfect authentic cadence at the very end of the piece.
