As previously reported, Ekso Bionics Holdings, Inc. (the “Company”) and Ekso Bionics, Inc., a wholly-owned subsidiary of the Company, entered into an agreement dated January 30, 2019 (the “JV Agreement”) with Zhejiang Youchuang Venture Capital Investment Co., Ltd. (“ZYVC”) and Shaoxing City Keqiao District Paradise Silicon Intelligent Robot Industrial Investment Partnership (Limited Partnership) relating to the establishment and operation of a joint venture company called Exoskeleton Intelligent Robotics Co. Limited (the “Joint Venture”). Pursuant to the JV Agreement, the Company has agreed to issue to the Joint Venture or a designee of ZYVC, within thirty (30) business days of the Joint Venture delivering its first batch of finished Ekso GT products to a buyer, shares of the Company’s common stock at a price per share equal to the volume weighted average of the closing price of the Company’s common stock on the Nasdaq Capital Market for the twenty (20) days prior to the date of issuance for an aggregate purchase price equal to $5,000,000, provided that the price per share at which such shares are issued shall be no less than $1.30 and no more than $1.96.

In connection with the Company entering into the JV Agreement, on March 8, 2019, the Company and the holders of outstanding warrants to purchase shares of the Company’s common stock (the “2015 Warrants” and such holders, the “2015 Warrant Holders”) issued pursuant to a securities purchase agreement dated December 23, 2015 (the “2015 Purchase Agreement”) entered into an amendment to the 2015 Purchase Agreement (the “Amendment”) to retroactively remove the provision in the 2015 Purchase Agreement prohibiting the Company from effecting or entering into an agreement to effect any issuance by the Company of its common stock at a price determined based on the trading price of the Company’s common stock or otherwise at a future determined price.

Pursuant to the Amendment, on March 8, 2019, the Company also entered into an amendment to each of the 2015 Warrants (each, a “Warrant Amendment”) with the respective 2015 Warrant Holder to reduce the exercise price of each such warrant from $3.74 per share to $2.75 per share, subject to further adjustments pursuant to the existing terms of such warrant.

A copy of the forms of the Amendment and the Warrant Amendment are attached to this current report as Exhibits 99.1 and 99.2, respectively, and each such Exhibit is incorporated by reference herein.
