If at any time while any Balance remains outstanding, the Company effects a Deemed Liquidation Event (without regard to any waiver of the treatment of a particular transaction or series of related transactions as a Deemed Liquidation Event pursuant to the terms of the  Charter) or a Reverse Merger, Holder may elect in writing to convert all (but not less than all) of the Balance of the Note then outstanding into Conversion Shares at the applicable Conversion Price contingent upon the completion of such Deemed Liquidation Event or Reverse Merger (such conversion, the “Extraordinary Event Conversion”).  The Company agrees that it shall give Holder at least ten (10) days advance notice of the anticipated closing of such Deemed Liquidation Event transaction or Reverse Merger (the “Deemed Liquidation Event Notice”).
