Pursuant to the Research Agreement, all rights, title and interest in the data, information and results obtained or arrived at by Washington U. in the performance of its services under the Research Agreement, as well as any patentable inventions obtained or arrived at in the performance of such services, will be jointly owned by the Company and Washington U., and each will have full right to practice and grant licenses in joint inventions. Additionally, Washington U. granted to the Company: (a) a non-exclusive, worldwide, royalty-free, fully paid-up, perpetual and irrevocable license to use and practice patentable inventions (other than joint inventions and improvements to Washington U.’s animal models) obtained or arrived at by Washington U. in the provision of its services under the Research Agreement (“University Inventions”) with respect to the self-cleaning shunt; and (b) an exclusive option to obtain an exclusive worldwide license in University Inventions, on terms to be negotiated between the parties.

Rights to inventions, improvements or discoveries, whether or not patentable or copyrightable made by at least one employee of WSU and one employee of the Company in the course of performance of the workplan agreed upon between the Company and WSU shall belong to WSU and the Company jointly. Both the Company and WSU will be free to use and license to others the rights of joint inventions for any and all purposes without consultation or obligation to the other party. WSU granted the Company a first option to negotiate an exclusive license to use and practice WSU inventions and its interest in the joint inventions as detailed in the WSU Agreement. Litigation: Litigation Resulting from 2017 Financing The Company lost its appeal of an adverse judgment in the 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 (Index No. 654581/2017). As a result, the Securities Purchase Agreement (the “SPA”) related to the Company’s June 8, 2017 equity financing (the “Financing”) was rescinded as it related to Sabby Healthcare Master Fund Ltd. and Sabby Volatility Warrant Master Fund Ltd. (“Sabby”), and the Company paid approximately $3,700 to Sabby in return for the 83,333 (post-stock split) shares of common stock Sabby purchased pursuant to the SPA. Soon after, the Company was named as the defendant in a lawsuit captioned Empery Asset Master Ltd., Empery Tax Efficient, LP, Empery Tax Efficient II, LP, Hudson Bay Master Fund Ltd., Plaintiffs, against Microbot Medical Inc., Defendant, in the Supreme Court of the State of New York, County of New York (the “Court”) (Index No. 651182/2020). The complaint alleges, among other things, that the Company breached multiple representations and warranties contained in the SPA, of which the Plaintiffs participated, and fraudulently induced Plaintiffs into signing the SPA. The complaint seeks rescission of the SPA and return of the Plaintiffs’ $6,750 purchase price with respect to the Financing. The Company filed a Motion to Dismiss on March 16, 2020, which Motion is pending before the Court. Alliance Litigation On April 28, 2019, the Company brought an action against Alliance Investment Management, Ltd. (“Alliance”) in the Southern District of New York under Section 16(b) of the Securities Exchange Act of 1934, 15 U.S.C. 78p(b), to compel Alliance to disgorge short swing profits realized from purchases and sales of the Company’s securities within a period of less than six months, executed while Alliance reported beneficial ownership of more than 10% of the Company’s outstanding common stock and statutory “insider” status for purposes of the statute. The case is Microbot Medical Inc. v. Alliance Investment Management, Ltd., No. 19-cv-3782-GBD (SDNY). The amount of profits the Company is seeking to divest is estimated to be approximately $480. On August 21, 2019, Alliance filed an answer to the action, claiming that an unnamed Alliance client was the “beneficial owner” of the shares reportedly held and traded by Alliance. On October 18, 21, and 28, 2019, Joseph Mona (“Mona”) filed Section 16(a) and Schedule 13G reports, which are substantially similar to the reports previously filed by Alliance. On October 28, 2019, Alliance filed a motion for summary judgment requesting that the Court dismiss the claims against Alliance in view of Mona’s SEC filings, which Alliance asserted revealed Mona as the client referenced in Alliance’s answer. On November 7, 2019, U.S. Magistrate Judge Robert W. Lehrburger ordered Alliance to produce relevant trading records, to enable the Company to determine whether to proceed against Alliance and/or Mona. Following Alliance’s production of Mona’s Microbot trading records, the Company filed a Second Amended Complaint on November 18, 2019, seeking to compel Alliance and/or Mona to disgorge profits realized from the trades they each separately reported. The Company continued to oppose Alliance’s Motion for Summary Judgment given Alliance’s refusal to confirm that the trades reported by Alliance referred exclusively to the trades executed in Mona’s account—and did not refer to duplicative trading executed by Alliance. Alliance’s Motion for Summary Judgment is pending. On February 4, 2020, Mona answered the 16(b) claim the Company asserted against him by claiming various equitable defenses, and filed a counterclaim against the Company under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. Mona admits to engaging in the reported short swing trading of the Company’s stock while a 10% beneficial owner and statutory 16(b) insider of the Company, but alleges that he was induced to buy the stock by various company misrepresentations. Mona claims a net loss on trading the Company’s stock of approximately $151. On March 6, 2020 the Company filed a motion for judgment on its 16(b) claim against Mona, together with a motion to dismiss Mona’s 10(b) counterclaim. Mona’s response to these motions is due on April 17, 2020. All parties are currently scheduled to appear in Court on May 26, 2020. Agreement with CardioSert Ltd. On January 4, 2018, Microbot Israel entered into an agreement with CardioSert Ltd. (“CardioSert”) to acquire certain patent-protected technology owned by CardioSert (the “Technology”). Pursuant to the Agreement, Microbot Israel made an initial payment of $50 to CardioSert and had 90-days to elect to complete the acquisition. 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 at $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). CardioSert agreed to assist Microbot Israel in the development of the Technology for a minimum of one year, for a monthly consultation fee of NIS 40,000 (or approximately US$11.50, based on an exchange rate of NIS3.47 to the dollar) covering up to 60 consulting hours per month. Yehezkel (Hezi) Himelfarb Resignation Effective as of February 1, 2019, Yehezkel (Hezi) Himelfarb, a member of the Board of Directors of the Company, and the Company’s Chief Operating Officer, resigned from all positions with the Company. Effective as of February 1, 2019, Mr. Himelfarb also resigned from his position as General Manager of Microbot Medical Ltd., a wholly owned subsidiary of the Company. As a result of Mr. Himelfarb providing certain post-resignation transition services to the Company until July 31, 2019, Mr. Himelfarb was paid his full salary and certain benefits through that date.
