All unpaid principal, together with any then unpaid and accrued interest payable hereunder, shall convert into equity securities of the Company as provided in Section 4 below if a Qualified Offering (as defined below) occurs prior to the Maturity Date. Otherwise, if such Qualified Offering has not occurred prior to the Maturity Date, this Note shall be due and payable at any time after the Maturity Date upon written demand to the Company by the Holder.  This Convertible Promissory Note (this “Note”) is unsecured in all respects. This Note is issued pursuant to that certain Bridge Note Purchase Agreement, dated                                              , 2016, by and among the Company and the Investors listed on Schedule 1 thereto, as the same may from time to time be amended, modified or supplemented (the “Purchase Agreement”).

3.                                      Events of Default. The occurrence of any one or more of the following events (whether such occurrence shall be voluntary or involuntary or occur or be effected by operation of law or otherwise) shall constitute an “Event of Default” hereunder:

(a)                                  if the Company fails to pay the entire amount of the principal and interest on this Note when due (either in cash or equity in accordance with the terms hereof); or

(c)                                   if any order, judgment, or decree is entered adjudicating the Company bankrupt or insolvent; or
