The Exif data is just the stuff that starts Exif and it is two bytes shorter than the length recorded for the APP1 marker. See TsuruZoh Tachibanaya's very excellent document; the one at MIT I referenced earlier: https://www.media.mit.edu/pia/Research/deepview/exif.html You will see from his example under "Exif data structure" that the FFD9 you see at the end of hte Exif data is the EOI for the thumbnail (which is at the end in both cases.)
