On November 13, 2017, the Company entered into a warrant exercise agreement with certain holders of outstanding warrants (the “Original Warrants”) to purchase up to an aggregate of 5,509,642 shares of the Company’s common stock at an exercise price of $1.69 per share. Pursuant to the terms of the warrant exercise agreement, each holder agreed to exercise, from time to time and in accordance with the terms of the Original Warrants, including certain beneficial ownership limitations set forth therein, all Original Warrants held by it for cash. As a result of the exercise of all of the Original Warrants, the Company received gross proceeds of approximately $9.3 million and net proceeds, after deducting estimated expenses paid or payable by the Company, of approximately $9.1 million.

 

Pursuant to the terms of the warrant exercise agreement, and in order to induce each holder to exercise its Original Warrants, the Company issued 1,377,411 new warrants to purchase a number of shares of its common stock which is equal to 25% of the number of shares of common stock received by such holders upon the cash exercise of its Original Warrants. The terms of the inducement warrants are substantially similar to the terms of the Original Warrants, except that the inducement warrants: (i) have an initial exercise price of $2.26 per share; (ii) become exercisable on May 13, 2018 and expire on November 13, 2019; and, (iii) contain certain additional transfer restrictions and limitations due to their offer and sale in a private placement offering.

 

Also on November 13, 2017, and in connection with its entry into the warrant exercise agreement, the Company agreed to issue warrants to purchase up to an aggregate of 1,138,300 shares of its common stock to the accredited investors that participated in the Company’s offerings completed in October 2017, in consideration for such investors agreement to waive certain covenants made by the Company to such investors and as an inducement to such investors to exercise certain other warrants to purchase the Company’s common stock. The terms of the October 2017 investor warrants are substantially similar to the terms of the new warrants, except that the October 2017 investor warrants will become exercisable only if and when each October 2017 investor exercises in full and for cash the warrants to purchase the Company’s common stock that were sold to such investors in the Company’s offerings completed in October 2017.

 

The warrants issued in connection with the warrant exercise agreement were considered inducement warrants and are classified in equity.

The fair value of the inducement warrants of $2.5 million was expensed as warrant inducement expense in the accompanying condensed consolidated statement of operations for the three and six months ended January 31, 2018.
