The 50,000 shares of preferred stock previously designated as Series A Junior Participating Preferred Stock were eliminated and returned to the status of authorized but unissued shares of preferred stock, without designation. Neuronetics’ stockholders are not required to take any action as a result of the expiration of the Rights Agreement. No shares of the Series A Junior Participating Preferred Stock were issued and outstanding at the time of filing of the Certificate of Elimination.

The foregoing is a summary of the terms of the Certificate of Elimination.
