1.                                      Amendment

Upon the consummation of the Merger (the “Effective Time”), the Option Grant shall be amended (and save where the context otherwise requires, any reference to the Option Grant in the remainder of this Agreement and elsewhere shall be read and construed as reference to the Option Grant as amended and novated by this Agreement) such that:

a.              Any reference in the Option Grant and this Agreement to “Stock Options” shall, as of the Effective Time, cease to represent an option to acquire shares of the Company’s common stock, par value $0.01 (the “Company Common Stock”) and shall be converted, as of the Effective Time, into an option to acquire that number of shares of Gener8’s common stock (“Parent Common Stock”) equal to the product obtained by multiplying (i) the number of shares of Company Common Stock subject to the Option Grant immediately prior to the Effective Time by (ii) the Exchange Ratio, at an exercise price per share equal to the quotient obtained by dividing (A) the per share exercise price specified in the Option Grant immediately prior to the Effective Time by (B) the Exchange Ratio; provided, however, that the exercise price and the number of shares of Parent Common Stock purchasable pursuant to the Option Grant will be determined in a manner consistent

with the requirements of Section 409A of the Code. The terms “Exchange Ratio” and “Code” as used herein shall have the meanings set forth in the Merger Agreement.

b.              Notwithstanding anything to the contrary set forth in the Option Grant or as a result of the consummation of the Merger and any changes in the Grantee’s position on the board of directors in connection therewith, the Stock Options, subject to the terms and conditions of the Option Grant as amended and novated in this Agreement, shall immediately vest and shall be exercisable by the Grantee at any time on or prior to July 8, 2017.
