Description of tranche consisting										The Company entered into a fee and release agreement with Canaccord Genuity LLC (“Canaccord Genuity”) requiring the Company to pay to Canaccord Genuity, in connection with a settlement, in addition to certain cash amounts, (i) $125 thousand in ordinary shares of the Company after the First Tranche Closing of the Timwell transaction and (ii) $225 thousand in ordinary shares of the Company after the closing of the Second Tranche of the Timwell transaction (or such lower amount if the Second Tranche Closing is less than $10.0 million). The price per share used for calculation of the number of ordinary shares issued by the Company to Canaccord Genuity is based on the volume weighted average price of the Company’s ordinary shares as reported on the Nasdaq Capital Market for the five consecutive trading days prior to the date of issuance. The Company is also obligated to pay $100 thousand in cash following the closing of the Third Tranche of $5.0 million (or such lower amount if the Third Tranche Closing is less than $5.0 million). Following the First Tranche Closing in May 15, 2018, the Company issued 4,715 ordinary shares to Canaccord Genuity.	The Company entered into an investment agreement with Timwell Corporation Limited, a Hong Kong corporation (“Timwell”), as amended on May 15, 2018 (the “Investment Agreement”), pursuant to which the Company agreed to issue to Timwell, in three different tranches, an aggregate of 640,000 ordinary shares in return for aggregate gross proceeds of $20 million. The closing of each tranche is subject to certain closing conditions. The closing of the first tranche (the “First Tranche Closing”) took place on May 15, 2018, upon which Timwell received 160,000 ordinary shares for an aggregate purchase price of $5,000,000, and Timwell and the Company signed a registration rights agreement in the form attached to the Investment Agreement. The net aggregate proceeds of the First Tranche Closing after deducting fees and other related expenses in the amount of approximately $705 thousands were approximately $4.3 million. The remaining investment is to occur in two tranches, including $10 million for the issuance to Timwell of 320,000 ordinary shares (the “Second Tranche”) and $5 million for the issuance to Timwell of 160,000 ordinary shares (the “Third Tranch”). The closing of the second and third tranches is subject to specified closing conditions, including, with respect to the second tranche, the signing of a license agreement and a supply agreement and the formation of the China JV (the “China JV”) based on the JV Framework Agreement, and, with respect to the third tranche, the successful production of certain ReWalk products by the China JV. The second tranche closing was initially expected to occur by July 1, 2018 and the third tranche closing was initially expected to occur by December 31, 2018 and no later than April 1, 2019.
