Assignor hereby represents

BrainBit, Inc. as a principal of the company, and that Assignor has not executed and will not execute any document or instrument in conflict
herewith. For the avoidance of doubt, it is acknowledged and agreed that this Assignment Agreement in no way limits the Assignor from
being affiliated with or employed by Brainbit, Inc. or otherwise working generally in the electroencephalography or neuro businesses,
provided the above representations and warranties are true as of the date hereof. For the avoidance of doubt, it is acknowledged that
the Proprietary Information and Inventions of Memory MD and Brain Scientific cannot be used by Assignor, BrainBit, Inc. or any other third
party at any time without a written licensing agreement.

 

Assignor acknowledges that
he will benefit from this assignment of the Inventions and Proprietary Information.

 

To the extent that any such
Invention or Proprietary Information is not assignable or transferable to Memory MD, Assignor hereby grants to Memory MD a non-exclusive,
royalty-free, irrevocable, perpetual, world-wide license to make, have made, modify, manufacture, reproduce, sub-license, use and sell
such non-assignable Invention or Proprietary Information.

 

I (Assignor) acknowledge that any breach or threatened
breach by me of any provision of this Agreement may result in immediate and irreparable injury to Memory MD, and that such injury may
not be readily compensable by monetary damages. In the event of any such breach or threatened breach, I acknowledge that, in addition
to all other remedies available at law and equity, Memory MD or its parent shall be entitled to seek equitable relief (including a temporary
restraining order, a preliminary injunction and/or a permanent injunction), and an equitable accounting of all earnings, profits or other
benefits arising from such breach and will be entitled to receive such other damages, direct or consequential, as may be appropriate.
