(c) No fractional shares or scrip representing fractional shares shall be issued upon the exercise of the rights under this Warrant. In lieu of such fractional share to which the Warranthholder would otherwise be entitled, the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction.

The term “Expiration Date” means September 25, 2017, as may be extended by the Company in its sole discretion, provided, however, that if the 2014 Requisite Majority has approved the Aggregate Warrant Amendment Offer, the Expiration Date shall be October 10, 2017.”
