Pursuant to the Warrant Amendments, the Company agreed to reduce the exercise price of all common stock warrants described above to $3.00 per share, and Intracoastal and Anson separately agreed to exercise all common stock warrants held by them. The proceeds from the exercise were approximately $2.6 million, which were received in October 2017. The Intracoastal and Anson Warrant Amendments also provide that the Company deliver to each of Anson and Intracoastal an additional warrant for common stock equal to 25% of the number of shares exercised, at an exercise price of $5.35 per share (collectively, the “Additional Warrants”). The Additional Warrants provided to Intracoastal and Anson are exercisable into 184,193 shares and 31,250 shares of common stock, respectively. The Additional Warrants are exercisable from the date of issuance and expire on the earlier of the close of business on the two-year anniversary of (i) the date the registration statement registering the resale of the underlying shares is declared effective by the SEC, or (ii) the commencement date that such Additional Warrant may be exercised by means of a “cashless exercise.” These Additional Warrants do not participate in the Cash Dividend or Spin-Off of the Business Combination Transaction. Whitehorse Warrant Amendments On November 3, 2017, the Company entered into warrant amendments (the "Whitehorse Warrant Amendments") with H.I.G. Whitehorse SMA ABF, L.P., H.I.G. Whitehorse SMA Holdings I, LLC and Whitehorse Finance, Inc., regarding an aggregate of 300,000 Whitehorse Warrants to purchase the Company’s common stock (the “Whitehorse Shares”), at an original exercise price of $5.0829 per share. Pursuant to the Whitehorse Warrant Amendments, the Company agreed to reduce the exercise price of all common stock warrants described above to $3.00 per share, and each warrant holder set forth above separately agreed to exercise all common stock warrants held by them within 30 days. Pursuant to the terms of the Whitehorse Warrant Amendments, the warrant holders are prohibited from engaging or otherwise agreeing to any sale, pledge, or other transfer of the Whitehorse Shares for a period of 120 days (the “Whitehorse Lock-Up Period”) following the exercise of such warrants in full. Following the Whitehorse Lock-Up Period, (i) the warrant holders may only sell such number of shares underlying the warrants representing up to 5% of the Company’s daily trading volume on the immediately prior trading day prior to a sale and (ii) the warrant holders may not transfer any of the Whitehorse Shares for less than $4.50 per share, provided that the warrant holders may not transfer any Whitehorse Shares unless the Company has an effective registration statement permitting the resale of the Whitehorse Shares. Provided that such warrant holders have exercised the Whitehorse Warrants, upon either the Record Date or the termination of the Business Combination Agreement, such warrant holders can require the Company to purchase from them all the Whitehorse Shares at a price of $4.50 per share. Acquisition consideration payable in stock In relation to the Q Interactive Acquisition, Selling Source, LLC (“Selling Source”), the seller, was entitled to receive additional consideration as it was concluded that the earn-out target (the “Q Interactive Earn-out Target”) specified in the purchase agreement had been met. As of September 30, 2017 and December 31, 2016, after certain measurement period adjustments, the net balance of acquisition consideration payable in stock of $10,225 was recognized. We used the probability-weighted method to determine the fair value of the acquisition consideration payable in stock, and this fair value assessment represents Level 3 measurements. It is classified as a non-current liability in the condensed consolidated balance sheets because this liability will be settled with the Company’s common stock. On November 3, 2017, the Company issued a total of 2,750,000 shares of common stock to settle the acquisition consideration payable in stock.
