Such statements are subject to a number of assumptions, risks and uncertainties which may cause actual results, performance or achievements to be materially different from those anticipated in these forward- looking statements. You should read statements that contain these words carefully because they discuss future expectations and plans which contain projections of future clinical studies, regulatory approvals, product candidate development, results of operations or financial condition or state other forward-looking information. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. Forward-looking statements are not historical facts, but instead represent only the Company’s beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of the Company’s control.

Control NOTE loss is visible in the dark patches of stained neurons on the right half. The left Synuclein aggregate half was an internal control and is unaffected. Synuclein aggregate with When the expression of A53T is turned on, but c-Abl deleted c-Abl is genetically deleted from the mouse brain, you don’t get any neurodegeneration. Thus, even though the clumps of a-syn are present in the right region of the brain, they don’t cause disease until c-Abl acts on them **: p < 0.0001, p = 0.0154, p = 0.0001, p = 0.0225, left-to-right 1 Brain 142:2380ff (2019) 7

SUMMARY Key points of Parkinson’s Disease Initiation and 1 Progression § Internalization of misfolded or aggregated a-synuclein and the activation of c-Abl in response is a key event in PD initiation/progression § The long-sought goal of clearing a-synuclein aggregates for a therapeutic purpose should focus on the aggregates WITHIN the affected neurons § Reduction and/or clearance of aggregates can be driven by restoring endogenous processes from within the affected neurons § Recovery of lost functional activity can be achieved 1 Werner and Olanow, Mov.
