date, the Company has not generated revenues from its operations. As of June 30, 2021, the Company had unrestricted cash and cash equivalent
balance of $&lt;span id="xdx_907_ecustom--UnrestrictedCashAndCashEquivalent_iI_pn3n3_c20210630_zSV00eYIjwc2" title="Unrestricted cash and cash equivalent"&gt;15,619&lt;/span&gt;, which management believes is sufficient to fund its operations for more than 12 months from the date of issuance
of these financial statements and sufficient to fund its operations necessary to continue development activities of its current proposed
products.&lt;/span&gt;&lt;/p&gt;

to continuing research and development activities, the Company expects to continue to incur additional losses for the foreseeable future.
While management of the Company believes that it has sufficient funds for more than 12 months, the Company may seek to raise additional
funds through future issuances of either debt and/or equity securities and possibly additional grants from the Israeli Innovation Authority
and other government institutions. The Company&#x2019;s ability to raise additional capital in the equity and debt markets is dependent
on a number of factors, including, but not limited to, the market demand for the Company&#x2019;s stock, which itself is subject to a
number of development and business risks and uncertainties, as well as the uncertainty that the Company would be able to raise such additional
capital at a price or on terms that are favorable to the Company.&lt;/span&gt;&lt;/p&gt;

epidemic of the coronavirus disease (&#x201c;COVID-19&#x201d;) is ongoing throughout the world. As the outbreak is still evolving, much
of its impact remains unknown. As of this filing, it is impossible to predict the effect and potential spread of the coronavirus disease
globally. The coronavirus disease may cause significant delays and disruptions to our pre-clinical studies.&lt;/span&gt;&lt;/p&gt;

travel restrictions have been implemented with respect to certain countries in an effort to contain the coronavirus disease, and several
countries have expanded screenings of travelers. As travel restrictions are increasingly implemented and extended to other countries,
the Company and its contract research organizations may be unable to visit its clinical trial sites and monitor the data from its clinical
trials on timely basis. The Company&#x2019;s employees may also face travel restrictions, which would impact its business. Furthermore,
some of the Company&#x2019;s manufacturers and suppliers are in Europe and may be impacted by port closures and other restrictions resulting
from the coronavirus outbreak, which may disrupt the Company&#x2019;s supply chain or limit its ability to obtain sufficient materials
for our products.&lt;/span&gt;&lt;/p&gt;

ultimate impact of the COVID-19 outbreak or similar health epidemics are highly uncertain and subject to changes, and the Company cannot
presently predict the scope and severity of any potential business shutdowns or disruptions. However, if the Company or any of the third
parties with whom the Company&#x2019;s engages, including the suppliers, animal trial sites, contract research organizations, regulators,
including the FDA health care providers and other third parties with whom the Company conducts business, were to experience shutdowns
or other business disruptions, the Company&#x2019;s ability to conduct our business and operations could be materially and negatively
impacted, which could prevent or delay the Company from obtaining approval for its devices.&lt;/span&gt;&lt;/p&gt;

2&lt;/b&gt; - Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets
and liabilities, unadjusted quoted prices in the markets that are not active, or other inputs that are observable or can be corroborated
by observable market data for substantially the full term of the assets or liabilities.&lt;/span&gt;&lt;/p&gt;

June 2016, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued ASU No. 2016-13, &#x201c;Financial Instruments &#x2013;
Credit Losses &#x2013; Measurement of Credit Losses on Financial Instruments&#x201d;, which introduces a model based on expected losses
to estimate credit losses for most financial assets and certain other instruments. In addition, for available-for-sale debt securities
with unrealized losses, the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. The
ASU is effective for smaller reporting companies for fiscal years, and interim periods within those fiscal years, beginning after December
15, 2022 (January 1, 2023 for the Company) &lt;span style="background-color: white"&gt;with early adoption permitted. The Company is currently
evaluating the impact this guidance may have on its consolidated financial statements and related disclosures&lt;/span&gt;.&lt;/span&gt;&lt;/p&gt;

December 2019, the FASB issued ASU 2019-12, &#x201c;Simplifying the Accounting for Income Taxes&#x201d; which eliminates the need for an
organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax
allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exceptions
in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also is designed to improve financial
statement preparers&#x2019; application of income tax-related guidance and simplify GAAP for (1) franchise taxes that are partially based
on income, (2) transactions with a government that result in a step-up in the tax basis of goodwill, (3) separate financial statements
of legal entities that are not subject to tax, and (4) enacted changes in tax laws in interim periods. &lt;span style="background-color: white"&gt;The
standard is effective for the Company on January 1, 2021 with early adoption permitted. The adoption of ASU 2019-12 on January 1, 2021
did not have a material impact on the Company&#x2019;s consolidated financial statements.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

June 2016, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued ASU No. 2016-13, &#x201c;Financial Instruments &#x2013;
Credit Losses &#x2013; Measurement of Credit Losses on Financial Instruments&#x201d;, which introduces a model based on expected losses
to estimate credit losses for most financial assets and certain other instruments. In addition, for available-for-sale debt securities
with unrealized losses, the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. The
ASU is effective for smaller reporting companies for fiscal years, and interim periods within those fiscal years, beginning after December
15, 2022 (January 1, 2023 for the Company) &lt;span style="background-color: white"&gt;with early adoption permitted. The Company is currently
evaluating the impact this guidance may have on its consolidated financial statements and related disclosures&lt;/span&gt;.&lt;/span&gt;&lt;/p&gt;

December 2019, the FASB issued ASU 2019-12, &#x201c;Simplifying the Accounting for Income Taxes&#x201d; which eliminates the need for an
organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax
allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exceptions
in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also is designed to improve financial
statement preparers&#x2019; application of income tax-related guidance and simplify GAAP for (1) franchise taxes that are partially based
on income, (2) transactions with a government that result in a step-up in the tax basis of goodwill, (3) separate financial statements
of legal entities that are not subject to tax, and (4) enacted changes in tax laws in interim periods. &lt;span style="background-color: white"&gt;The
standard is effective for the Company on January 1, 2021 with early adoption permitted. The adoption of ASU 2019-12 on January 1, 2021
did not have a material impact on the Company&#x2019;s consolidated financial statements.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

have lease agreements with lease and non-lease components, which we account for as a single lease component. Variable lease payments
based on an index or rate are initially measured using the index or rate in effect at the lease commencement and included in the measurement
of the lease liability; thereafter, changes to lease payments due to rate or index updates are recorded as rent expense in the period
incurred. We have elected not to recognize ROU assets and lease liabilities for short-term leases that have a term of &lt;span id="xdx_908_eus-gaap--LesseeOperatingLeaseTermOfContract_iI_dt_c20210630__srt--RangeAxis__srt--MaximumMember_zugvDKiyqIn5" title="Short-term lease term"&gt;12 months&lt;/span&gt; or less.
The effect of short-term leases on our ROU assets and lease liabilities was not material. Our lease agreements do not contain any material
residual value guarantees or material restrictive covenants. In addition, we do not have any related party leases and our sublease transactions
are de minimis.&lt;/span&gt;&lt;/p&gt;

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 &#x201c;SPA&#x201d;) related to the Company&#x2019;s June
8, 2017 equity financing (the &#x201c;Financing&#x201d;) was rescinded as it related to Sabby Healthcare Master Fund Ltd. and Sabby Volatility
Warrant Master Fund Ltd. (&#x201c;Sabby&#x201d;), and the Company paid approximately $&lt;span id="xdx_90F_eus-gaap--LitigationSettlementAmountAwardedToOtherParty_pn3n3_c20210101__20210630__us-gaap--TypeOfArrangementAxis__custom--SecuritiesPurchaseAgreementMember_zls7sK1W4jhe" title="Settlement amount"&gt;3,700&lt;/span&gt; to Sabby in return for the &lt;span id="xdx_909_ecustom--NumberOfPoststockSplitSharesReturned_c20210101__20210630__us-gaap--TypeOfArrangementAxis__custom--SecuritiesPurchaseAgreementMember_pdd" title="Number of post-stock split shares returned"&gt;83,333&lt;/span&gt; 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

Inc., Defendant, in the Supreme Court of the State of New York, County of New York (the &#x201c;Court&#x201d;) (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&#x2019; $&lt;span id="xdx_908_eus-gaap--LossContingencyDamagesSoughtValue_c20210101__20210630__us-gaap--TypeOfArrangementAxis__custom--SecuritiesPurchaseAgreementMember_pn3n3" title="Purchase price of plaintiffs"&gt;6,750&lt;/span&gt; purchase price with respect to the Financing. The Company filed a Motion to Dismiss on March
16, 2020, which was denied &lt;span style="color: windowtext"&gt;by decision and order entered &lt;/span&gt;on February 17, 2021.&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s management is unable to assess the likelihood that it would be successful in any trial with respect to the SPA or the
Financing, having previously lost the Sabby lawsuit. Accordingly, no assurance can be given that if the Company goes to trial and ultimately
loses, or if the Company decides to settle at any time, such an adverse outcome would not be material to the Company&#x2019;s consolidated
financial position.&lt;/span&gt;&lt;/p&gt;
