On July 11, 2017, the Company entered into amended and restated warrants with certain holders (the “Holders”) of warrants previously issued in March 2016 (the “Amended March 2016 Warrant”) and between December 2016 and March 2017 (the “Amended March 2017 Warrants” and together with the Amended March 2016 Warrant, the “Amended and Restated Warrants”). Pursuant to their terms, the Amended and Restated Warrants supersede and replace the previously issued warrants. Under the terms of the Amended and Restated Warrants, the Company may, at its sole discretion, opt to exchange no fewer than all of the Amended and Restated Warrants for 1,617,917 common shares, as adjusted for the Company’s share consolidation effective July 11, 2017. Between July 14, 2017 and July 20, 2017, the Company notified the Holders of its intent to exchange all of the Amended and Restated Warrants, which exchange shall automatically occur on the third business day after such notice is duly given.
