The exposition starts out in c minor with the left and right hands playing in unison. They're in unison for pretty much the entire first period from measures 1-9. It's both parallel and symmetrical containing a HC and a PAC. Measures 9-17 seem to hint at 2 two-bar phrases that make a period, but then there is a long extension of a sixteenth note scale pattern that crescendos into a HC at measure 17. Following this, there is a direct modulation to the relative major, E flat. Starting in bar 17, there is a parallel symmetrical period with an HC followed by a PAC. Then there's a terminative closing section to the exposition which sounds like a repetition with variants of the last phrase. All of this repeats before we move on to the development.
Bars 25-38 sounds like the entire development section to me. There's a lot of tonality changes going on. The same general structure is kept from the exposition, only there are many variants on it.
38 to the end is the recapitulation. From this point until bar 54 there is a near exact repeat of the first period of the entire piece. The runs are changed a little, but other than that I don't see any other changes. 54-80ish is the recap of the second period of the piece. It modulates back to c minor toward the end of the first phrase of this period. Then from 80 to the end we have the closing section. It sounds a lot different than the rest of the piece, primarily because it's really soft and slow compared to everything that was going on earlier. It's all a variant on the second group motive. After a fermata, the last two lines of the piece are suddenly forte and back up to tempo.
