Litigation The Company is named as the defendant in a lawsuit, captioned Sabby Healthcare Master Fund Ltd. and Sabby Volatility Warrant Master Fund Ltd., Plaintiffs, against Microbot Medical Inc., Defendant, in the Supreme Court of the State of New York, County of New York (the “Matter”). The complaint alleged, among other things, that the Company breached multiple representations and warranties contained in the Securities Purchase Agreement (the “SPA”) related to the June 8, 2017 equity financing of the Company (the “Financing”), of which the Plaintiffs participated. The complaint originally sought rescission of the SPA and return of the Plaintiffs’ $3,375 purchase price with respect to the Financing, and damages in an amount to be determined at trial, but alleged to exceed $1,000. On February 28, 2019, the Court issued its Decision and Order After Trial, finding for the Plaintiffs and ordering that the SPA be rescinded and that the parties be restored to the status quo ante. The rescission would require the Plaintiffs to transfer back to the Company the shares they purchased pursuant to the SPA, and the Company to return to the Plaintiffs their purchase price of $3,375. As such, the Company recorded a short-term liability of $3,375 with an offset to shareholders’ equity as of December 31, 2018 with respect to the court’s decision. On March 27, 2019, the Company filed a Notice of Appeal and an Undertaking to stay execution of the judgment pending appeal. If the Company loses on appeal, it also has to pay interest on the judgment from the judgment date at a 9% per annum rate. Tolling and Standstill Agreement On April 4, 2018, the Company entered into a Tolling and Standstill Agreement (the “Tolling Agreement”) with Empery Asset Master, Ltd., Empery Tax Efficient LP, Empery Tax Efficient II LP, and Hudson Bay Master Fund, Ltd., the other investors in the Financing (the “Other Investors”).

No provision has been recorded with respect to the Tolling Agreement since no settlement was reached with respect to the Matter. Agreement with CardioSert Ltd.

At the end of the 90-day period, at Microbot Israel’s sole option, CardioSert shall assign and transfer the Technology to Microbot Israel and Microbot Israel shall pay to CardioSert additional amounts and securities as determined in the agreement. On April 10, 2018, Microbot delivered an Exercise Notice to CardioSert Ltd., notifying it that Microbot elected to exercise the option to acquire the Technology owned by CardioSert and therefore made an additional cash payment of $250 and 6,738 shares of common stock (100,000 shares of common stock before the Reverse Split) estimated of $74. The agreement may be terminated by Microbot Israel at any time for convenience upon 90-days’ notice. The agreement may be terminated by CardioSert in case the first commercial sale does not occur by the third anniversary of the date of signing of the agreement except if Microbot Israel has invested more than $2,000 in certain development stages, or the first commercial sale does not occur within 50 months. In each of the above termination events, or in case of breach by Microbot Israel, CardioSert shall have the right to buy back the Technology from Microbot Israel for $1.00, upon 60 days prior written notice, but only 1 year after such termination. Additionally, the agreement may be terminated by either party upon breach of the other (subject to cure).
