5,865,102 Pre-Funded Warrants to Purchase Shares of Common Stock

We are offering 5,865,102 shares of our common stock.

We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if any such purchaser so chooses, pre-funded warrants, in lieu of shares of common stock that would otherwise result in such purchaser’s beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. The purchase price of each pre-funded warrant will be equal to the price per share at which shares of common stock are sold to the public in this offering, minus $0.01, and the exercise price of each pre-funded warrant will be $0.01 per share. This offering also relates to the shares of common stock issuable upon exercise of any pre-funded warrants sold in this offering. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. For each pre-funded warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis.

Our common stock is listed on The Nasdaq Capital Market under the symbol “MBOT.” On November 16 , 2018, the last reported sale price of our common stock on The Nasdaq Capital Market was $ 3.41 per share. The public offering price per share and any pre-funded warrant will be determined between us and the underwriter at the time of pricing, and may be at a discount to the current market price. There is no established public trading market for the pre-funded warrants and the Underwriter’s Warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the pre-funded warrants and the Underwriter’s Warrants on any national securities exchange or other nationally recognized trading system.

Overview

Our Company

Microbot is a pre-clinical medical device company specializing in the research, design and development of next generation robotic endoluminal surgery devices targeting the minimally invasive surgery space. Microbot is primarily focused on leveraging its micro-robotic technologies with the goal of improving surgical outcomes for patients.

Microbot’s current technological platforms, ViRobTM, CardioSertTM and TipCATTM , are comprised of proprietary innovative technologies. Using the ViRob platform, Microbot is currently developing its first product candidate: the Self Cleaning Shunt, or SCSTM, for the treatment of hydrocephalus and Normal Pressure Hydrocephalus, or NPH. Although the SCS utilizes one of our platforms, we are focused on the development of a Multi Generation Pipeline Portfolio utilizing all three of our proprietary technologies.

Microbot has a patent portfolio of 25 issued/allowed patents and 15 patent applications pending worldwide.

Technological Platforms

ViRob

The ViRob is an autonomous crawling micro-robot which can be controlled remotely or within the body. Its miniature dimensions are expected to allow it to navigate and crawl in different natural spaces within the human body, including blood vessels, the digestive tract and the respiratory system as well as artificial spaces such as shunts, catheters, ports, etc. Its unique structure is expected to give it the ability to move in tight spaces and curved passages as well as the ability to remain within the human body for prolonged time. The SCS product was developed using the ViRob technology.

CardioSert

On May 25, 2018, Microbot acquired a patent-protected technology from CardioSert Ltd., a privately-held medical device company based in Israel. The CardioSertTM technology contemplates a combination of a guidewire and microcatheter, technologies that are broadly used for surgery within a tubular organ or structure such as a blood vessel or duct. The CardioSertTM technology features a unique guidewire delivery system with steering and stiffness control capabilities which when developed is expected to give the physician the ability to control the tip curvature, to adjust tip load to varying degrees of stiffness in a gradually continuous manner. The CardioSertTM technology was originally developed to support interventional cardiologists in crossing chronic total occlusions (CTO) during percutaneous coronary intervention (PCI) procedures and has the potential to be used in other spaces and applications, such as peripheral intervention, and neurosurgery. CardioSertTM was part of a technological incubator supported by the Israel Innovation Authorities (formerly known as the Office of the Chief Scientist, or OCS), and a device based on the technology has successfully completed pre-clinical testing.

TipCAT

The TipCAT is a disposable self-propelled locomotive device that is specially designed to advance in tubular anatomies. The TipCAT is a mechanism comprising a series of interconnected balloons at the device’s tip that provides the TipCAT with its forward locomotion capability. The device can self-propel within natural tubular lumens such as the blood vessels, respiratory and the urinary and GI tracts. A single channel of air/fluid supply sequentially inflates and deflates a series of balloons creating an inchworm like forward motion. The TipCAT maintains a standard working channel for treatments. Unlike standard access devices such as guidewires, catheters for vascular access and endoscopes, the TipCAT does not need to be pushed into the patient’s lumen using external pressure; rather, it will gently advance itself through the organ’s anatomy. As a result, the TipCAT is designed to be able to reach every part of the lumen under examination regardless of the topography, be less operator dependent, and greatly reduce the likelihood of damage to lumen structure. The TipCAT thus offers functionality features equivalent to modern tubular access devices, along with advantages associated with its physiologically adapted self-propelling mechanism, flexibility, and design.

Industry Overview

CSF Management

Hydrocephalus is a medical condition in which there is an abnormal accumulation of cerebrospinal fluid, or CSF, in the brain that can cause increased intracranial pressure. It is estimated that one in every 500 babies are born with hydrocephalus, and over 1,000,000 people in the United States currently live with hydrocephalus.

Symptoms of hydrocephalus vary with age, disease progression and individual tolerance to the condition, but they can include convulsion, tunnel vision, mental disability or dementia-like symptoms and even death. NPH is a type of hydrocephalus that usually occurs in older adults. NPH is generally treated as distinct from other types of hydrocephalus because it develops slowly over time. In NPH, the drainage of CSF is blocked gradually and the excess fluid builds up slowly. This slow accumulation means that the fluid pressure may not be as high as in other types of hydrocephalus. It is estimated that more than 700,000 Americans have NPH, but less than 20% receive an appropriate diagnosis.

Hydrocephalus is most often treated by the surgical insertion of a shunt system. The shunt system diverts the flow of CSF from the brain’s ventricles (or the lumbar subarachnoid space) to another part of the body where the fluid can be more readily absorbed. Hydrocephalus shunt designs have changed little since their introduction in the 1950s. A shunt system typically consists of three parts: the distal tubing or shunt (a flexible and sturdy plastic tube), the ventricular catheter (the proximal catheter), and a valve. The end of the shunt system with the proximal catheter is placed in the ventricles (within the CSF) and the distal catheter is placed in the site of the body where the CSF can be drained. A valve is located along the shunt to maintain and regulate the rate of CSF flow. Current systems can be created from separate components or bought as complete units.

The treatment of hydrocephalus with existing shunt systems often includes complications. For example, approximately 50% of shunts used in the pediatric population fail within two years of placement and repeated neurosurgical operations are often required. Ventricular catheter blockage, or occlusion, is by far the most frequent event that results in shunt failure. Shunt occlusion occurs when there is a partial or complete blockage of the shunt that causes it to function intermittently or not at all. Such a shunt blockage can be caused by the accumulation of blood cells, tissue, or bacteria in any part of the shunt system. In the event of shunt occlusion, CSF begins to accumulate in the brain or lumbar region again and the symptoms of untreated hydrocephalus can reappear until a shunt replacement surgery is performed.

Although several companies are active in the field of hydrocephalus treatment and the manufacturing of shunt systems and shunt components, Microbot believes that the majority of those companies are focusing on the development of valves. The development of a “smart shunt” – a shunt that could provide data to the physician on patient conditions and shunt function with sensor-based controls, or correct the high failure rate of existing shunt systems – is for the most part at an academic and conceptual level only. Reports of smart shunt technologies are typically focused on a subset of components with remaining factors left unspecified, such as hardware, control algorithms or power management. Microbot does not believe that a smart shunt that can prevent functional failures has been developed to date. Because of the limited innovation in this area, Microbot believes an opportunity exists to provide patients suffering from hydrocephalus or NPH with a more effective instrument for treating their condition.

An alternative, short-term solution to hydrocephalus is the implantation of an External Ventricular Drainage, or EVD, an implanted device used in neurosurgery for the short-term treatment and monitoring of elevated intracranial pressure when the normal flow of CSF inside the brain is obstructed. If after using an EVD, the underlying hydrocephalus does not eventually resolve, the EVD may then be converted to a cerebral shunt, a fully internalized, long-term treatment for hydrocephalus.

EVDs are also used in other instances when the normal flow of CSF inside the brain is obstructed, such as a result of head trauma, intracerebral hemorrhage, brain tumors and infection. The EVD serves to divert excess fluids from the brain and allows for the monitoring of intracranial pressure. An EVD must be placed in a center with full neurosurgical capabilities because immediate neurosurgical intervention may be needed if a complication of EVD placement, such as bleeding, is encountered. EVD is one of the most commonly used and most important life-saving procedures in the neurologic ICU, with more than 200,000 neuro-intensive patients requiring EVD insertions annually.

Similar to shunts, EVDs are also prone to occlusion, mostly due to cellular debris, such as blood clots and/or tissue fragments. Studies have shown that approximately 1-7% of EVDs require replacement secondary to occlusion. Current solutions for EVD occlusion include irrigation and replacement, which we believe may be ineffective (in the case of irrigation) or costly (in the case of replacement) and in either case, put the patient at risk of unintended side effects. Microbot believes that with its portfolio of technologies, and its initial pre-clinical results, it is well-positioned to explore and expand its offerings as an alternative solution for EVD occlusion.

Minimally Invasive Endovascular Neurosurgery

Minimally Invasive Surgery, or MIS, refers to surgical procedures performed through tiny incisions instead of a single large opening. Because the incisions are small, patients tend to have quicker recovery times and experience less trauma than with conventional surgery. The global MIS market is expected to exceed $50 billion by 2019, with a CAGR of over 20% through 2023. MIS involves three major category of devices: surgical, monitoring and visualization, and endoscopy. The market for surgical devices, including ablation, electrosurgery and medical robotic systems, accounts for the largest share of revenue and is also expected to show the highest rate of growth.

As a subset of MIS, endovascular neurosurgery refers to surgeries performed by using devices that pass through the blood vessels to diagnose and treat neurological diseases and conditions such as stroke, arteriovenous malformations, aneurysms and atherosclerosis, rather than using open surgery.

The global neurovascular device market was valued at $1.62 billion in 2015 and is expected to reach a value of $2.92 billion by 2024, growing at a CAGR of 6.5%. Increases in the geriatric population and a rise in the number of patients suffering from neurovascular disorders, implementation of advanced technological platforms, and favorable reimbursement policies across established markets are expected to drive this market’s growth. On the other hand, the high cost of the endovascular devices and scarcity of neurovascular surgeons may impede such growth.

Stroke is a devastating condition, affecting 33 million people worldwide every year. In the United States alone, there are nearly 800,000 instances of stroke yearly, with about three in four being first-time strokes. This number is expected to increase to one million annually in 2021. Stroke is the fifth leading cause of death in the United States and is a leading cause of long-term disability, with related care costs estimated at $70 billion annually.

Mechanical thrombectomy has only been approved as a first-line treatment for ischemic stroke since 2016. Prior to such aproval, chemical thrombolysis using tissue plasminogen activators was the only first-line treatment available, limiting the therapeutic window for ischemic stroke patients to as little as 3-4 hours from the onset of symptoms. With mechanical thrombectomy, treatment can be started within 6-24 hours of the time the patient was last known to be well. The US mechanical thrombectomy market is projected to grow at a CAGR of 23.9% between 2014-2020, to reach a value over $350 million.

According to the Brain Aneurysm Foundation, an estimated 6 million people in the United States have an unruptured brain aneurysm, or 1 in 50 people. The annual rate of rupture is approximately 8 – 10 per 100,000 people, or about 30,000 people in the United States annually. Embolic coiling is the established gold-standard treatment for aneurysms, and the most established product line in the neurovascular market – it is a strong but relatively stagnant market, projected to grow at a CAGR of 1.7% between 2014-2020, to reach a value of over $800 million. New devices that improve treatment of complex aneurysms, such as embolization-enabling stents, bifurcations stents, flow-diversion stents, liquid embolics and intrasaccular devices, are expected to boost market growth.

The major companies in the field of neurovascular devices include Stryker Corporation, Medtronic Plc., Cerenovus (Johnson & Johnson), Terumo Corporation and Penumbra, Inc. Neurovascular access devices are the means for delivering neurovascular treatment tools and devices from an opening in the femoral or radial arteries into the brain vasculature. Such access devices include sheaths, guidewires and microcatheters. Wires and catheters account for 18.6% of the overall neurovascular market.

Navigating and placing access devices through tortuous and highly delicate brain arteries is a complex procedure that requires high-level surgical skills with specialist training. In many procedures, surgeons exchange numerous access devices before reaching the target and applying the therapeutic agent or device, increasing the risk of adverse events and the exposure of both patient and physician to radiation. Adverse events, such as perforation of brain arteries or the release of embolies from a thrombus or atherosclerotic lesion can have devastating or even fatal results.

Microbot believes that with its portfolio of technologies specifically CardioSertTM and TipCAT, it is well-positioned to explore and develop such technologies as neurovascular access devices, with a focus on improving the ease and access and enhancing the safety of endovascular neurosurgery.

Our Product Pipeline

Self-Cleaning Shunt

The SCS device is designed to act as the ventricular catheter portion of a CSF shunt system that is used to relieve hydrocephalus and NPH. It is designed to work as an alternative to any ventricular catheter options currently on the market and to connect to all existing shunt system valves currently on the market; therefore, the successful commercialization of the SCS is not dependent on any single shunt system. Initially, Microbot expects the SCS device to be an aftermarket purchase that would be deployed to modify existing products by the end user. Microbot believes that the use of its SCS device will be able to reduce, and potentially eliminate, shunt occlusions, and by doing so, Microbot believes its SCS has the potential to become the gold standard ventricular shunt in the treatment of hydrocephalus and NPH.

The SCS device embeds an internal robotic cleaning mechanism in the lumen, or inside space, of the ventricular catheter which prevents cell accumulation and tissue ingrowth into the catheter. The SCS device consists of a silicone tube with a perforated titanium tip, which connects to a standard shunt valve at its distal end. The internal cleaning mechanism is embedded in the lumen of the titanium tip. Once activated, the cleaning mechanism keeps tissue from entering the catheter perforations while maintaining the CSF flow in the ventricular catheter.

The internal cleaning mechanism of the SCS device is activated by means of an induced magnetic field, which is currently designed to be externally generated by the patient through a user-friendly headset that transmits the magnetic field at a pre-determined frequency and operating sequence protocol. The magnetic field that is created by the headset is then captured by a flexible coil and circuit board that is placed just under the patient’s scalp in the location where the valve is located. The circuit board assembly converts the magnetic field into the power necessary to activate the cleaning mechanism within the proximal part of the ventricular catheter.

Microbot has completed the development of an SCS prototype and is currently completing the safety testing, general proof of concept testing and performance testing for the device, which Microbot began in mid-2013. In May 2018, Microbot announced the results of two pre-clinical studies assessing the SCS, an in-vitro study and a small animal study. The in-vitro study, which was performed at Wayne State University by Dr. Carolyn Harris, supports the SCS’s potential as a viable technology for preventing occlusion in shunts used to treat hydrocephalus. The animal study designed to assess the safety profile of the SCS, which was performed by James Patterson McAllister, PhD, a Professor of Neurosurgery at Washington University School of Medicine in St. Louis, met the primary goal to determine the safety of the SCS device that aims to prevent obstruction in CSF catheters. Since the completion of these initial studies, Microbot has commenced a follow-up study to further evaluate the safety and to investigate the efficacy of the SCS. The follow-up study is also being conducted by leading hydrocephalus experts at Washington University and Wayne State University. The study will include a larger sample size compared to the initial studies and the primary and secondary endpoints will seek to validate the safety and efficacy of the SCS that will be activated in both in-vitro (lab) and in-vivo (animal) models. Microbot plans to use the findings for initial regulatory submissions in the United States, Europe and other jurisdictions, although upon the completion of animal studies, Microbot may conduct clinical trials if they are requested by the FDA or if Microbot decides that the data from such trials would improve the marketability of the product candidate. Microbot believes that the animal study results of its first generation SCS device should be available during the second half of 2019 and we expect to submit that data to the FDA either in a regulatory submission or as part of a pre-submission meeting request, depending on the final results of this ongoing studies. The proposed indication for use of the SCS device would be for the treatment of hydrocephalus as a component of a shunt system when draining or shunting of CSF is indicated. It continues to be possible that the FDA could require us to conduct a human clinical study to support the safety and efficacy of the SCS and that such clinical data would need to be submitted as part of a 510(k) notification to authorize marketing of the medical device in the U.S.

Microbot may also conduct clinical trials for the SCS in other countries where such trials are necessary for Microbot to sell its SCS device in such country’s market, although it has no current plans to do so.

TipCAT

A TipCAT prototype was shown to self-propel and self-navigate in curved plastic pipes and curved ex-vivo colon. In addition, in its first feasibility study, the prototype device was tested in a live animal experiment and successfully self-propelled through segments of the animal’s colon, with no post-procedural damage. All tests were conducted at AMIT (Alfred Mann Institute of Technology at the Technion), prior to the licensing of TipCAT by Microbot.

Microbot is no longer pursuing the development of the TipCAT as a colonoscopy tool but is currently exploring the use of the TipCAT for minimally invasive endovascular neurosurgical applications.

On November 29, 2016, our common stock began trading on the Nasdaq Capital Market under the symbol “MBOT”. Prior to the Merger, we were a biopharmaceutical company that operated in one segment, the research, development, and commercialization of stem cell therapeutics and related technologies. Substantially all of the material assets relating to the stem cell business were sold on November 29, 2016.

In May 2016, we effected a 1-for-12 reverse split of our common stock, and in November 2016, we effected a 1-for-9 reverse split of our common stock in connection with the Merger. In September 2018, we effected a 1-for-15 reverse split of our common stock. The share and per share information described in this prospectus that occurred prior to these reverse splits have been adjusted to give retrospective effect to the reverse splits.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should consider carefully the risks described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks and uncertainties discussed under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017, before deciding whether to purchase our securities in this offering. All of these risk factors are incorporated herein in their entirety. The risks described below and incorporated by reference are material risks currently known, expected or reasonably foreseeable by us. However, the risks described below or that we incorporate by reference are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition. If any of these risks actually materialize, our business, prospects, financial condition, and results of operations could be seriously harmed. This could cause the trading price of our common stock and the value of the warrants to decline, resulting in a loss of all or part of your investment.

Risks Relating to the Development and Commercialization of Microbot’s Product Candidates

Microbot’s business depends heavily on the success of its lead product candidate, the SCS. If Microbot is unable to commercialize the SCS or experiences significant delays in doing so, Microbot’s business will be materially harmed.

On January 27, 2017, Microbot entered into a research agreement with Washington University in St. Louis to develop the protocol for and to execute the necessary animal study to determine the effectiveness of the Microbot’s SCS prototype. The initial research was completed in 2017 with a comprehensive study expected to be completed in 2019. Upon the completion of animal studies, Microbot may conduct clinical trials if they are requested by the FDA or if Microbot decides that the data from such trials would improve the marketability of the product candidate. After all necessary clinical and performance data supporting the safety and effectiveness of SCS are collected, Microbot must still obtain FDA clearance or approval to market the device and those regulatory processes can take several months to several years to be completed. Therefore, Microbot’s ability to generate product revenues will not occur for at least the next few years, if at all, and will depend heavily on the successful commercialization of SCS in the treatment of hydrocephalus. The success of commercializing SCS will depend on a number of factors, including the following:

| ● | our ability to obtain additional capital;
| ● | successful completion of animal studies and, if necessary, human clinical trials and the collection of sufficient data to demonstrate that the device is safe and effective for its intended use;
| ● | receipt of marketing approvals or clearances from the FDA and other applicable regulatory authorities;
| ● | establishing commercial manufacturing arrangements with one or more third parties;
| ● | obtaining and maintaining patent and trade secret protections;
| ● | protecting Microbot’s rights in its intellectual property portfolio;
| ● | establishing sales, marketing and distribution capabilities;
| ● | generating commercial sales of SCS, if and when approved, whether alone or in collaboration with other entities;
| ● | acceptance of SCS, if and when commercially launched, by the medical community, patients and third-party payors;
| ● | effectively competing with existing shunt and endoscope products on the market and any new competing products that may enter the market; and
| ● | maintaining quality and an acceptable safety profile of SCS following clearance or approval.

If Microbot does not achieve one or more of these factors in a timely manner or at all, it could experience significant delays or an inability to successfully commercialize SCS, which would materially harm its business.

Microbot’s ability to expand our technology platforms for other uses, including endovascular neurosurgery other than for the treatment of hydrocephalus, may be limited.

After spending time working with experts in the field, Microbot has recently decided to no longer pursue the use of TipCAT in colonoscopy and has instead committed to focus on expanding all of its technology platforms for use in segments of the endovascular neurosurgery market, including traumatic brain injury, to capitalize on its existing competencies in hydrocephalus and the market’s needs. Microbot’s ability to expand its technology platforms for use in the endovascular neurosurgery market will be limited by its ability to develop and/or refine the necessary technology, obtain the necessary regulatory approvals for their use on humans, and the marketing of its products and otherwise obtaining market acceptance of its product in the United States and in other countries.

7

Microbot operates in a competitive industry and if its competitors have products that are marketed more effectively or develop products, treatments or procedures that are similar, more advanced, safer or more effective, its commercial opportunities will be reduced or eliminated, which would materially harm its business.

Our competitors that have developed or are developing endoluminal robotics surgical systems include Corindus Vascular Robotics, Inc., Hansen Medical, Inc. Auris Health, Inc., Stereotaxis, Inc., Medrobotics Corporation and others. Our competitors may develop products, treatments or procedures that directly compete with our products and potential products and which are similar, more advanced, safer or more effective than ours. The medical device industry is very competitive and subject to significant technological and practice changes. Microbot expects to face competition from many different sources with respect to the SCS and products that it is seeking to develop or commercialize with respect to its other product candidates in the future.

Competing against large established competitors with significant resources may make establishing a market for any products that it develops difficult which would have a material adverse effect on Microbot’s business. Microbot’s commercial opportunities could also be reduced or eliminated if its competitors develop and commercialize products, treatments or procedures quicker, that are safer, more effective, are more convenient or are less expensive than the SCS or any product that Microbot may develop. Many of Microbot’s potential competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than Microbot may have. Mergers and acquisitions in the medical device industry market may result in even more resources being concentrated among a smaller number of Microbot’s potential competitors.

At this time, Microbot does not know whether the FDA will require it to submit clinical data in support of its future marketing applications for its SCS product candidate, particularly in light of recent initiatives by the FDA to enhance and modernize its approach to medical device safety and innovation, which creates uncertainty for Microbot as well as the possibility of increased product development costs and time to market.

Microbot anticipates that its lead product candidate, the SCS, will be classified by the FDA as Class II and thus be eligible for marketing pursuant to a cleared 510(k) notification. However, there is no guarantee that the FDA will agree with the Company’s determination or that the FDA would accept the predicate device that Microbot intends to submit in its 510(k) notification in order to establish that its new device product is substantially equivalent to one or more predicate devices. The FDA also may request additional data in response to a 510(k) notification, or require Microbot to conduct further testing or compile more data in support of its 510(k) submission. Such additional data could include clinical data that must be derived from human clinical studies that are designed appropriately to address the potential questions from the FDA regarding a proposed product’s safety or effectiveness. It is unclear at this time whether and how various activities recently initiated or announced by the FDA to modernize the U.S. medical device regulatory system could affect the marketing pathway or timeline for our product candidate, given the timing and the undeveloped nature of some of the FDA’s new medical device safety and innovation initiatives. One of the recent initiatives was announced in April 2018, when the FDA Commissioner issued a statement with the release of a Medical Device Safety Action Plan. Among other key areas of the Medical Device Safety Action Plan, the Commissioner stated that the FDA is “exploring what further actions we can take to spur innovation towards technologies that can make devices and their use safer. For instance, our Breakthrough Device Program that helps address unmet medical needs can be used to facilitate patient access to innovative new devices that have important improvements to patient safety. We’re considering developing a similar program to support the development of safer devices that do not otherwise meet the Breakthrough Program criteria, but are clearly intended to be safer than currently available technologies.” This type of program may negatively affect our existing development plan for the SCS product candidate or it may benefit Microbot, but at this time those potential impacts from recent FDA medical device initiatives are unknown and uncertain. Similarly, the FDA Commissioner announced various agency goals under a Medical Innovation Access Plan in 2017.

If the FDA does require clinical data to be submitted as part of the SCS marketing submission, any type of clinical study performed in humans will require the investment of substantial expense, professional resources and time. In order to conduct a clinical investigation involving human subjects for the purpose of demonstrating the safety and effectiveness of a medical device, a company must, among other things, apply for and obtain Institutional Review Board, or IRB, approval of the proposed investigation. In addition, if the clinical study involves a “significant risk” (as defined by the FDA) to human health, the sponsor of the investigation must also submit and obtain FDA approval of an Investigational Device Exemption, or IDE, application. Microbot may not be able to obtain FDA and/or IRB approval to undertake clinical trials in the United States for any new devices Microbot intends to market in the United States in the future. Moreover, the timing of the commencement, continuation and completion of any future clinical trial may be subject to significant delays attributable to various causes, including scheduling conflicts with participating clinicians and clinical institutions, difficulties in identifying and enrolling patients who meet trial eligibility criteria, failure of patients to complete the clinical trial, delay in or failure to obtain IRB approval to conduct a clinical trial at a prospective site, and shortages of supply in the investigational device.

8

Thus, the addition of one or more mandatory clinical trials to the development timeline for the SCS would significantly increase the costs associated with developing and commercializing the product and delay the timing of U.S. regulatory authorization. The current uncertainty regarding near-term medical device regulatory changes by the FDA could further affect our development plans for the SCS, depending on their nature, scope and applicability. Microbot and its business, financial condition and operating results could be materially and adversely affected as a result of any such costs, delays or uncertainty.

Risks Related to this Offering

You will experience immediate and substantial dilution if you purchase securities in this offering.

As of September 30, 2018, our net tangible book value was approximately $ 6.57 million, or $ 2.2066 per share. Since the price per share of our common stock being offered in this offering is substantially higher than the net tangible book value per share of our common stock, you will suffer substantial dilution with respect to the net tangible book value of the common stock you purchase in this offering. Based on the assumed public offering price of  $ 3.41 per share of common stock being sold in this offering (the last reported sale price of our common stock on The Nasdaq Capital Market on November 16 , 2018), and our net tangible book value per share as of September 30, 2018, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of  $ 0.6421 per share with respect to the net tangible book value of the common stock. See the section entitled “Dilution” for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering. The discussion above assumes (i) no sale of pre-funded warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis until such warrants are exercised and (ii) no exercise by the underwriter of the Underwriter’s Warrants.

There is no public market for the pre-funded warrants being offered in this offering.

There is no established public trading market for the pre-funded warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any securities exchange or nationally recognized trading system, including The Nasdaq Capital Market. Without an active market, the liquidity of the pre-funded warrants will be limited.

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the purposes described in the section entitled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management may not apply the net proceeds from this offering in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing securities or as otherwise provided in our investment policies in effect from time to time. These investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

We are subject to a lawsuit that could adversely affect our business and our use of proceeds from this offering.

We are named as the defendant in a lawsuit, which we refer to as the Matter, captioned Sabby Healthcare Master Fund Ltd. and Sabby Volatility Warrant Master Fund Ltd., Plaintiffs, against Microbot Medical Inc., Defendant, pending in the Supreme Court of the State of New York, County of New York (the “Court”) (Index No. 654581/2017). The complaint alleges, among other things, that we breached multiple representations and warranties contained in the Securities Purchase Agreement (the “SPA”) related to our June 8, 2017 equity financing, or the Financing, of which the Plaintiffs participated. The complaint seeks rescission of the SPA and return of the Plaintiffs’ $3,375,000 purchase price with respect to the Financing, and damages in an amount to be determined at trial, but alleged to exceed $1 million. On August 3, 2018, both Plaintiffs and Defendant filed motions for summary judgment. On September 27, 2018, the Court heard oral argument on the parties’ respective summary judgment motions. After oral argument, the Court denied Plaintiffs’ motion in its entirety from the bench. On September 28, 2018, the Court issued a decision granting our motion for summary judgment regarding Plaintiffs’ claim for monetary damages and denying our motion for summary judgment on Plaintiffs’ claim for rescission, finding that there were material questions of fact that would need to be resolved at trial. A trial date has been set for February 11, 2019.

On April 4, 2018, we entered into a Tolling and Standstill 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, of whom we refer to as the Other Investors. Pursuant to the Tolling Agreement, among other things, (a) the Other Investors agree not to bring any claims against us arising out of the Matter, (b) the parties agree that if we reach an agreement to settle the claims asserted by the Sabby Funds in the above suit, we will provide the same settlement terms on a pro rata basis to the Other Investors, and the Other Investors will either accept same or waive all of their claims and (c) the parties froze in time the rights and privileges of each party as of the effective date of the Tolling Agreement, until (i) an agreement to settle the suit is executed; (ii) a judgment in the suit is obtained; or (iii) the suit is otherwise dismissed with prejudice.

We believe that the claims are without merit and have been and intend to continue to defend the action vigorously. However, management is unable to assess the likelihood of the claim and the amount of potential damages, if any, to be awarded. Accordingly, no assurance can be given that any adverse outcome would not be material to our consolidated financial position. Additionally, in the event the court holds for the Plaintiffs in the Matter and we lose our appeals, we will likely be required to use the proceeds from this offering or available cash towards payment of damages to the Plaintiffs and the Other Investors, that we otherwise would have used to build our business and develop our technologies into commercial products. In such event, we would be required to raise additional capital sooner than we otherwise would, of which we can give no assurance of success.

There may be future sales of our securities or other dilution of our equity, which may adversely affect the market price of our common stock.

We are generally not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The market price of our common stock could decline as a result of sales of common stock or securities that are convertible into or exchangeable for, or that represent the right to receive, common stock after this offering or the perception that such sales could occur.

Holders of pre-funded warrants purchased in this offering will have no rights as common stockholders until such holders exercise their pre-funded warrants and acquire our common stock.

Until holders of pre-funded warrants acquire shares of our common stock upon exercise of the pre-funded warrants, holders of pre-funded warrants will have no rights with respect to the shares of our common stock underlying such pre-funded warrants. Upon exercise of the pre-funded warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

Even if this offering is successful, we will need to raise additional capital in the future to continue operations, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed may force us to delay, limit or terminate our product development efforts or other operations.

We have had significant recurring losses from operations and we do not generate any cash from operations and must raise additional funds in order to continue operating our business. We expect to continue to fund our operations in the future primarily through equity and debt financings, grants from the Israel Innovation Authority and other sources. If additional capital is not available to us when needed or on acceptable terms, we may not be able to continue to operate our business pursuant to our business plan or we may have to discontinue our operations entirely. As of September 30 , 2018, we had cash and cash equivalents of approximately $ 6.7 million. We estimate that we will receive net proceeds of approximately $ 17.9 million from the sale of the securities offered by us in this offering, based on the assumed public offering price of  $ 3.41 per share (the last reported sale price of our common stock on The Nasdaq Capital Market on November 16 , 2018) and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering. In the event of a decrease in the net proceeds to us from this offering as a result of a decrease in the assumed public offering price or the number of shares offered by us, if the Plaintiffs succeed in the Matter or if our use of proceeds changes from our plans as described under “Use of Proceeds”, we may need to raise additional capital sooner than we anticipate. In addition, we cannot provide assurances that our plans will not change or that changed circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. Our ability to raise additional funds will depend, in part, on the success of our product development activities, any clinical trials, regulatory events, our ability to identify and enter into in-licensing or other strategic arrangements, and other events or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyond our control. There can be no assurances that sufficient funds will be available to us when required or on acceptable terms, if at all.

If we are unable to secure additional funds when needed or on acceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of our development programs or other operations, dispose of technology or assets, pursue an acquisition of our company by a third party at a price that may result in a loss on investment for our stockholders, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologies or potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financial condition and results of operations. Moreover, if we are unable to obtain additional funds on a timely basis, there will be substantial doubt about our ability to continue as a going concern and increased risk of insolvency and up to a total loss of investment by our stockholders.

USE OF PROCEEDS

We estimate that we will receive net proceeds of approximately $ 17.9 million (or approximately $ 20.7 million if the underwriter’s over-allotment option is exercised in full) from the sale of the securities offered by us in this offering, based on the assumed public offering price of  $ 3.41 per share (the last reported sale price of our common stock on The Nasdaq Capital Market on November 16 , 2018), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering.

A $ 0.25 increase (decrease) in the assumed public offering price of  $ 3.41 per share would increase (decrease) the expected net proceeds to us from this offering by approximately $ 1.4 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering.

Similarly, a one million share increase (decrease) in the number of shares offered by us, as set forth on the cover page of this prospectus, would increase (decrease) the net proceeds to us by approximately $ 3.1 million, assuming the assumed public offering price of  $ 3.41 per share remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering.

We currently intend to use the net proceeds from this offering for attaining regulatory approvals for and commercializing our SCS device in the treatment of hydrocephalus and NPH; expanding and developing the applications of our existing ViRob and SCS IP and prototypes into other areas of CSF management, such as EVD, through regulatory submission; developing the CardioSertTM technology for neurovascular disorders from proof of concept to pre-clinical studies; and for working capital and other general corporate purposes. See “Risk Factors” for a discussion of certain risks that may affect our intended use of the net proceeds from this offering, including with respect to the Matter. We may also use a portion of the net proceeds from this offering to in-license, acquire, or invest in complementary businesses, technologies, products or assets. However, we have no current commitments or obligations to do so.

We currently anticipate that our existing resources, together with the expected net proceeds from this offering, will be sufficient to fund our planned operations until December 2021.

Our expected use of net proceeds from this offering represents our current intentions based upon our present plans and business condition. As of the date of this prospectus, we cannot currently allocate specific percentages of the net proceeds that we may use for the purposes specified above, and we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering, or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual use of the net proceeds will vary depending on numerous factors, including our ability to obtain additional financing, the progress, cost and results of our preclinical and clinical development programs and whether we are able to enter into future licensing or collaboration arrangements. We may find it necessary or advisable to use the net proceeds for other purposes, and our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds from this offering.

Pending the use of the net proceeds from this offering, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

(1) | Adjusted for our one-for-fifteen reverse stock split on September 4, 2018.

As of November 16 , 2018, there were approximately 184 holders of record of our common stock, which excludes stockholders whose shares were held in nominee or street name by brokers. The actual number of common stockholders is greater than the number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

DIVIDEND POLICY

We have never paid cash dividends on our common stock and we do not anticipate paying cash dividends on common stock in the foreseeable future. The payment of dividends on our common stock will depend on earnings, financial condition, debt covenants in place, and other business and economic factors affecting us at such time as our Board of Directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on a stockholders’ investment will only occur if our stock price appreciates.

14

DILUTION

Our historical net tangible book value as of September 30, 2018 was approximately $ 6.57 million, or $ 2.2066 per share of common stock. Our historical net tangible book value is the amount of our total tangible assets less our liabilities. Historical net tangible book value per common share is our historical net tangible book value divided by the number of shares of common stock outstanding as of September 30, 2018.

After giving effect to the sale of  5,865,102 shares of our common stock at the assumed public offering price of  $ 3.41 per share (the last reported sale price of our common stock on The Nasdaq Capital Market on November 16 , 2018), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering, our as adjusted net tangible book value as of September 30, 2018 would have been approximately $ 24.5 million, or $ 2.7679 per share of common stock. This represents an immediate increase in as adjusted net tangible book value of $ 0.5613 per share to our existing stockholders, and an immediate dilution of $ 0.6421 per share to new investors purchasing securities in this offering at the assumed public offering price.

The following table illustrates this dilution on a per share basis:

Assumed public offering price per share |  |  |  |  |  | $ | 3.4100 |
Historical net tangible book value per share as of September 30, 2018 |  | $ | 2.2066 |  |  |  |  |
Pro forma increase in net tangible book value per share attributable to investors in this offering |  |  | 0.5613 |  |  |  |  |
As adjusted net tangible book value per share after this offering |  |  |  |  |  |  | 2.7679 |
Dilution per share to investors participating in this offering |  |  |  |  |  | $ | 0.6421 |

If the underwriter exercises in full its option to purchase up to 879,765 additional shares of common stock at the assumed public offering price of  $ 3.41 per share (the last reported sale price of our common stock on The Nasdaq Capital Market on November 16 , 2018), the as adjusted net tangible book value after this offering would be approximately $27.2 million, or $ 2.8013 per share, representing an increase in net tangible book value of $ 0.5947 per share to existing stockholders and immediate dilution in net tangible book value of  $ 0.6087 per share to investors purchasing our securities in this offering at the assumed public offering price.

Each $0.25 increase (decrease) in the assumed public offering price of $3.41 per share of common stock would increase (decrease) the as adjusted net tangible book value by $0.1527 per share of common stock and the dilution to new investors by $0.0973 per share, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the estimated placement agent fees and expenses and estimated offering expenses payable by us.

We may also increase or decrease the number of shares we are offering. An increase of 1,000,000 shares offered by us, as set forth on the cover page of this prospectus, would increase our as adjusted net tangible book value by approximately $3.1 million, or approximately $0.0378 per share of common stock, and decrease the dilution per share to investors in this offering by approximately $0.0378 per share, assuming that the assumed public offering price per share of common stock remains the same, and after deducting the estimated placement agent fees and expenses and estimated offering expenses payable by us. Similarly, a decrease of 1,000,000 shares offered by us, as set forth on the cover page of this prospectus, would decrease our as adjusted net tangible book value by approximately $3.1 million, or approximately $0.0471 per share, and increase the dilution per share to investors in this offering by approximately $0.0471 per share, assuming that the assumed public offering price per share of common stock remains the same, and after deducting the estimated placement agent fees and expenses and estimated offering expenses payable by us. The information discussed above is illustrative only and will adjust based on the actual public offering price, the actual number of shares of common stock that we offer in this offering, our actual expenses, and other terms of this offering determined at pricing.

The foregoing discussion and table does not take into account further dilution to investors in this offering that could occur upon the exercise of outstanding options and warrants, including the pre-funded warrants offered pursuant to this offering and the Underwriter’s Warrants, having a per share exercise price less than the public offering price per share in this offering.

The foregoing discussion and table are based on 2,9 7 5,676 shares of common stock outstanding as of September 30, 2018, and excludes, as of September 30, 2018:

| ● | 4 2 2,478 shares of our common stock issuable upon the exercise of outstanding stock options, with exercise prices ranging from $0 to $19.35 and having a weighted-average exercise price of $11.70 per share;
| ● | 211,239 shares of our common stock reserved for future grant under our 2017 Equity Incentive Plan;
| ● | Approximately 7,531 shares of our common stock issuable upon the exercise of outstanding warrants, with exercise prices ranging from approximately $40.00 to $2,885 per share and having a weighted-average exercise price of $1,967 per share; and
| ● | An aggregate of approximately 36,667 shares of our common stock issuable upon the conversion of 550 shares of our Series A Convertible Preferred Stock.

To the extent that options, warrants or other convertible securities outstanding as of September 30, 2018 have been or may be exercised, converted or other shares issued, investors purchasing securities in this offering may experience further dilution. In addition, we may seek to raise additional capital in the future through the sale of equity or convertible debt securities. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PRINCIPAL STOCKHOLDERS

The following table sets forth information regarding beneficial ownership of our capital stock, as of November 16 , 2018, by:

| ● | each of our directors;
| ● | each of our named executive officers;
| ● | all of our current directors and executive officers as a group; and
| ● | all those known by us to be to a beneficial owner of more than 5% of the Company’s common stock.

In general, “beneficial ownership” refers to shares that an individual or entity has the power to vote or dispose of, and any rights to acquire common stock that are currently exercisable or will become exercisable within 60 days of November 16 , 2018. We calculated percentage ownership in accordance with the rules of the SEC. The percentage of common stock beneficially owned is based on 2,975,676 shares outstanding as of November 16 , 2018. In addition, shares issuable pursuant to options or other convertible securities that may be acquired within 60 days of November 16 , 2018 are deemed to be issued and outstanding and have been treated as outstanding in calculating and determining the beneficial ownership and percentage ownership of those persons possessing those securities, but not for any other persons.

This table is based on information supplied by each prospective director, officer and principal stockholder of the Company. Except as indicated in footnotes to this table, the Company believes that the stockholders named in this table have sole voting and investment power with respect to all shares of Common Stock shown to be beneficially owned by them, based on information provided by such stockholders. Unless otherwise indicated, the address for each director, executive officer and 5% or greater stockholder of the Company listed is: c/o Microbot Medical Inc., 25 Recreation Park Drive, Unit 108, Hingham, MA 02043.

DESCRIPTION OF CAPITAL STOCK

As of the date of this prospectus, we are authorized to issue up to 221,000,000 shares of capital stock, par value $0.01 per share, divided into two classes designated, respectively, “common stock” and undesignated “preferred stock.” Of such shares authorized, 220,000,000 shares are designated as common stock, and 1,000,000 shares are designated as undesignated preferred stock.

The following is a summary of the material terms of our capital stock and certain provisions of our restated certificate of incorporation and amended and restated bylaws. Since the terms of our certificate of incorporation and bylaws, and Delaware law, are more detailed than the general information provided below, you should only rely on the actual provisions of those documents and Delaware law. If you would like to read those documents, they are on file with the SEC, as described under the heading “Where You Can Find Additional Information” below. The summary below is also qualified by provisions of applicable law.

On September 4, 2018, we filed a Certificate of Amendment (the “Amendment”) to our Restated Certificate of Incorporation to implement a 1-for-15 reverse split of our common stock (the “Reverse Stock Split”). As a result of the Reverse Stock Split, each fifteen shares of our issued and outstanding common stock were automatically combined and converted into one issued and outstanding share of common stock. The Reverse Stock Split affected all issued and outstanding shares of the Company’s common stock and preferred stock, as well as common stock underlying stock options, preferred stock and warrants outstanding immediately prior to the effectiveness of the Reverse Stock Split. The Amendment did not decrease the number of authorized shares of the Company’s common stock, nor did it alter the par value of common stock, which remained at $0.01 per share, or modify any voting rights or other terms of our common stock or preferred stock. Unless otherwise indicated, all information set forth in this prospectus gives effect to the Reverse Stock Split.

As of November 16 , 2018, there were 2,975,676 shares of common stock outstanding that were held of record by approximately 184 stockholders, although we believe that there is a significantly larger number of beneficial owners of our common stock.

Common Stock

Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Holders of common stock are entitled to receive proportionately any dividends as may be declared by our board of directors, out of funds that we may legally use to pay dividends, subject to any preferential dividend rights of any outstanding series of preferred stock or series of preferred stock that we may designate and issue in the future. All shares of common stock outstanding as of the date of this prospectus and, upon issuance and sale, all shares of common stock that we may offer pursuant to this prospectus, will be fully paid and nonassessable.

In the event of our liquidation or dissolution, the holders of common stock are entitled to receive proportionately our net assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to the common stock.

Preferred Stock

General

We have authority to issue up to 1,000,000 shares of preferred stock, par value $0.01 per share. As of September 30, 2018, we had 550 shares of Series A Convertible Preferred Stock issued and outstanding that can convert into an aggregate of approximately 36,667 shares of our common stock. As of the date of this prospectus, no other shares of our preferred stock were outstanding or designated.

Our board of directors is authorized, without stockholder approval, from time to time, to issue shares of preferred stock in series and may, at the time of issuance, subject to Delaware law and our certificate of incorporation and by-laws, determine the rights, preferences and limitations of each series, including voting rights, dividend rights and redemption and liquidation preferences. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of our common stock. Holders of shares of preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of our company before any payment is made to the holders of shares of our common stock. In some circumstances, the issuance of shares of preferred stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management. Upon the affirmative vote of our board of directors, without stockholder approval, we may issue shares of preferred stock with voting and conversion rights which could adversely affect the holders of shares of our common stock.

17

If we issue a specific series of preferred stock, we will file a copy of the certificate establishing the terms of the preferred stock with the Secretary of State of the State of Delaware and with the SEC. To the extent required, this description will include:

| ● | the title and stated value;
| ● | the number of shares offered, the liquidation preference per share and the purchase price;
| ● | the dividend rate(s), period(s) and/or payment date(s), or method(s) of calculation for such dividends;
| ● | whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;
| ● | the procedures for any auction and remarketing, if any;
| ● | the provisions for a sinking fund, if any;
| ● | the provisions for redemption, if applicable;
| ● | any listing of the preferred stock on any securities exchange or market;
| ● | whether the preferred stock will be convertible into our common stock, and, if applicable, the conversion price (or how it will be calculated) and conversion period;
| ● | whether the preferred stock will be exchangeable into debt securities, and, if applicable, the exchange price (or how it will be calculated) and exchange period;
| ● | voting rights, if any, of the preferred stock;
| ● | a discussion of any material and/or special U.S. federal income tax considerations applicable to the preferred stock;
| ● | the relative ranking and preferences of the preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of the affairs of the Company; and
| ● | any material limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of the Company.

Series A Preferred Stock

In December 2016 and May 2017, we filed a Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible Preferred Stock, or the Series A Certificate of Designation, with the Secretary of State of the State of Delaware, establishing and designating an aggregate of 12,991 shares of the Series A Preferred Stock. Each share of Series A Preferred Stock is convertible, at any time at the option of the holder thereof, into 1,000 shares of common stock, subject to certain adjustments and subject to the ownership limitation described below. The Series A Preferred Stock has no sinking provisions, dividend rights, liquidation preference or other preferences over common stock and has no voting rights except as provided in the Series A Certificate of Designation or as otherwise required by law.

The Series A Preferred Stock contains limitations that prevent the holder from acquiring shares upon conversion of shares of series A preferred stock that would result in the number of shares beneficially owned by the holder and its affiliates exceeding 4.99% of the total number of shares of our common stock then issued and outstanding, which limitation may be increased to 9.99% at the option of the holder. In addition, upon certain changes in control of Microbot, holders of shares of Series A Preferred Stock can elect to receive, subject to certain limitations and assumptions, securities in a successor entity equal to the value of the holders’ Series A Preferred Stock, or if holders of common stock are given a choice of cash or property, then cash or property equal to the value of the holder’s outstanding Series A Preferred Stock.

As of September 30, 2018, we had 550 shares of Series A Preferred Stock issued and outstanding, convertible into an aggregate of approximately 36,667 shares of our common stock, and no shares of Series A Preferred Stock are available for issuance.

Outstanding Warrants

As of September 30, 2018, we had outstanding:

| ● | warrants to purchase approximately 2,770 shares of our common stock at an exercise price of approximately $40.00 per share, which are exercisable through March 14, 2022, and which are subject to “full ratchet” price-based anti-dilution adjustments;
| ● | warrants to purchase approximately 683 shares of our common stock at an exercise price of approximately $1,363 per share, which are exercisable through April 30, 2020; and
| ● | warrants to purchase approximately 183 shares of our common stock at an exercise price of approximately $2,725 per share, which are exercisable through April 9, 2023.

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering 5,865,102 shares of our common stock or pre-funded warrants to purchase shares of our common stock. The shares of common stock or pre-funded warrants will be issued separately. We are also registering the shares of common stock issuable from time to time upon exercise of the pre-funded warrants offered hereby.

Common Stock

The material terms and provisions of our common stock and each other class of our securities which qualifies or limits our common stock are described under the caption “Description of Capital Stock” in this prospectus.

Pre-Funded Warrants

The following summary of certain terms and provisions of pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants.

Duration and Exercise Price. Each pre-funded warrant offered hereby will have an initial exercise price per share equal to $0.01. The pre-funded warrants will be immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.

Exercisability. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s pre-funded warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. Purchasers of pre-funded warrants in this offering may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding common stock. No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, we will either pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share.

Cashless Exercise. If, at the time a holder exercises its pre-funded warrants, a registration statement registering the issuance of the shares of common stock underlying the pre-funded warrants under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants.

Transferability. Subject to applicable laws, a pre-funded warrant may be transferred at the option of the holder upon surrender of the pre-funded warrant to us together with the appropriate instruments of transfer.

Exchange Listing. There is no trading market available for the pre-funded warrants on any securities exchange or nationally recognized trading system. We do not intend to list the pre-funded warrants on any securities exchange or nationally recognized trading system.

Right as a Stockholder. Except as otherwise provided in the pre-funded warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the pre-funded warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their pre-funded warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the pre-funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction.

The underwriting agreement provides that the obligation of the underwriter to purchase the shares of common stock and/or pre-funded warrants offered by this prospectus is subject to certain conditions.

Delivery of the shares of common stock and any pre-funded warrants to purchasers is expected on or about , 2018, subject to certain customary closing conditions.

The underwriter proposes to offer the shares of common stock and/or pre-funded warrants purchased pursuant to the underwriting agreement to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of  $ per share or per pre-funded warrant. After this offering, the public offering price and concession may be changed by the underwriter. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus.

In connection with the sale of the common stock and/or pre-funded warrants to be purchased by the underwriter, the underwriter will be deemed to have received compensation in the form of underwriting commissions and discounts. The underwriter’s commissions and discounts will be 7% of the gross proceeds of this offering, or $ per share of common stock or per pre-funded warrant.

We have also agreed to pay to the underwriter a management fee equal to 1% of the aggregate gross proceeds raised in this offering. We estimate the total expenses payable by us for this offering, excluding the underwriting discounts and commissions, to be approximately $ 500,000 , which includes (i) a $35,000 non-accountable expense allowance payable to the underwriter, (ii) reimbursement of the accountable expenses of the underwriter up to $125,000, including the legal fees of the underwriter, (iii) if applicable, reimbursement of documented costs of clearing agent settlement and financing up to $10,000 and (iv) other estimated expenses, which include legal, accounting, printing costs and various fees associated with the registration and listing of our securities sold in this offering in a total estimated amount of $ 340,000 .

We have also agreed to pay the underwriter a tail fee equal to the cash and warrant compensation in this offering if any investor which the underwriter contacted or introduced us to during the term of the underwriter’s engagement (other than investors who have a pre-existing relationship with us) provides us with further capital in a public or private offering or capital raising transaction and such offering or transaction is consummated during the six-month period following termination or expiration of that certain engagement letter, dated October 12, 2018, entered into between us and the underwriter.

In addition, we have agreed to issue to the underwriter warrants (the “Underwriter’s Warrants”) to purchase up to 337,243 shares of common stock, which represents 5% of the aggregate number of shares of common stock and pre-funded warrants sold in this offering (including the number of shares of common stock issuable upon exercise of the option to purchase additional securities), at an exercise price of $ per share (representing 125% of the public offering price per share of common stock to be sold in this offering). The Underwriter’s Warrants will be exercisable immediately and shall expire five years following the effective date of this offering. Pursuant to FINRA Rule 5110(g), the Underwriter’s Warrants and any shares issued upon exercise of the Underwriter’s Warrants shall not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following the date of effectiveness or commencement of sales of this offering, except the transfer of any security: (i) by operation of law or by reason of our reorganization; (ii) to any FINRA member firm participating in the offering and the officers or partners thereof, if all securities so transferred remain subject to the lock-up restriction set forth above for the remainder of the time period; (iii) if the aggregate amount of our securities held by the underwriter or related persons do not exceed 1% of the securities being offered; (iv) that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member manages or otherwise directs investments by the fund and the participating members in the aggregate do not own more than 10% of the equity in the fund; or (v) the exercise or conversion of any security, if all securities remain subject to the lock-up restriction set forth above for the remainder of the time period.

Option to Purchase Additional Securities

We have granted to the underwriter an option, exercisable not later than 30 days after the date of this prospectus, to purchase up to an additional 879,765 shares of common stock at the public offering price, less the underwriting discounts and commissions, set forth on the cover page of this prospectus. If any additional shares of common stock are purchased pursuant to such option, the underwriter will offer these securities on the same terms as those on which the securities are being offered hereby.

Right of First Refusal

We have also granted the underwriter a right of first refusal for a period of twelve months following the closing of this offering to act as sole book-running manager, sole underwriter or sole placement agent for each and every future public offering or private placement of equity or debt securities by us or any of our subsidiaries.

Lock-up Agreements

Our Section 16 (under the Exchange Act) officers and directors have agreed with the underwriter to be subject to a lock-up period of 90 days following the date of this prospectus. This means that, during the applicable lock-up period, such persons may not offer for sale, contract to sell, sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any of our shares of common stock or any securities convertible into, or exercisable or exchangeable for, shares of common stock. Certain limited transfers are permitted during the lock-up period if the transferee agrees to these lock-up restrictions.

We have also agreed, in the underwriting agreement, to similar lock-up restrictions on the issuance and sale of our shares of common stock, or any securities convertible into, or exercisable or exchangeable for, shares of common stock, for 90 days following the closing of this offering, subject to certain exceptions.

The underwriter may, in its sole discretion and without notice, waive the terms of any of these lock-up agreements.

Stabilization, Short Positions and Penalty Bids

The underwriter may engage in syndicate covering transactions, stabilizing transactions and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of our common stock:

| ● | Syndicate covering transactions involve purchases of securities in the open market after the distribution has been completed in order to cover syndicate short positions. Such a naked short position would be closed out by buying securities in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.
| ● | Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specific maximum.
| ● | Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

21

These syndicate covering transactions, stabilizing transactions and penalty bids may have the effect of raising or maintaining the market prices of our securities or preventing or retarding a decline in the market prices of our securities. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. Neither we nor the underwriter make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected on the Nasdaq Capital Market, in the over-the-counter market or on any other trading market and, if commenced, may be discontinued at any time.

In connection with this offering, the underwriter also may engage in passive market making transactions in our common stock in accordance with Regulation M during a period before the commencement of offers or sales of our securities in this offering and extending through the completion of the distribution. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for that security. However, if all independent bids are lowered below the passive market maker’s bid that bid must then be lowered when specific purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of our securities. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that any transactions, once commenced, will not be discontinued without notice.

Indemnification

We have agreed to indemnify the underwriter against certain liabilities, including certain liabilities arising under the Securities Act, or to contribute to payments that the underwriter may be required to make for these liabilities.

Determination of Offering Price

The actual offering price of the securities we are offering will be negotiated between us and the underwriter based on the trading of our common stock prior to the offering, among other things, and may be at a discount to the current market price.

Electronic Offer, Sale and Distribution of Securities

A prospectus in electronic format may be made available on the websites maintained by the underwriter, if any, participating in this offering and the underwriter may distribute prospectuses electronically. Other than the prospectus in electronic format, the information on these websites is not part of this prospectus or the registration statement of which this prospectus form a part, has not been approved or endorsed by us or the underwriter, and should not be relied upon by investors.

Other Relationships

The underwriter and its respective affiliates may in the future engage in investment banking and other commercial dealings in the ordinary course of business with us or our affiliates.

Listing

Our common stock is listed on The Nasdaq Capital Market under the symbol “MBOT.” We do not plan to list the pre-funded warrants or the Underwriter’s Warrants on The Nasdaq Capital Market or any other securities exchange or trading market.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

MICROBOT MEDICAL, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Microbot Medical, Inc. and its subsidiary (the “Company”) as of December 31, 2017 and 2016 and the related consolidated statements of comprehensive loss, stockholders’ equity and cash flows for each of the two years in the period ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”).

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

NOTE 1 - GENERAL

| A. | Description of business:

Microbot Medical Inc. (the “Company”) is a pre-clinical medical device company specializing in the research, design and development of next generation micro-robotics assisted medical technologies targeting the minimally invasive surgery space. The Company is primarily focused on leveraging its micro-robotic technologies with the goal of improving surgical outcomes for patients.

It was incorporated on August 2, 1988 in the State of Delaware under the name Cellular Transplants, Inc. The original Certificate of Incorporation was restated on February 14, 1992 to change the name of the Company to Cyto Therapeutics, Inc. On May 24, 2000, the Certificate of Incorporation as restated was further amended to change the name of the Company to StemCells, Inc.

On November 28, 2016, the Company consummated a transaction pursuant to an Agreement and Plan of Merger, dated August 15, 2016, with Microbot Medical Ltd., a private medical device company organized under the laws of the State of Israel (“Microbot Israel”), and C&RD Israel Ltd. (“Merger Sub”), an Israeli corporation and wholly-owned subsidiary of the Company, whereby Merger Sub merged with and into Microbot Israel and Microbot Israel surviving as a wholly-owned subsidiary of the Company (the “Merger”). Pursuant to the terms of the Merger, at the effective time of the Merger, each outstanding ordinary share of Microbot Israel capital stock was converted into the right to receive approximately 0.2 shares (2.9 shares before the Reverse Split described below) of the Company’s common stock, par value $0.01 per share, after giving effect to a one for nine reverse stock splits of the date of the merger, for an aggregate of 1,788,884 shares (26,550,974 shares before the Reverse Split) of Company’s common Stock issued to the former Microbot Israel shareholders. In addition, all outstanding options to purchase the ordinary shares of Microbot Israel were assumed by the Company and converted into options to purchase an aggregate of 176,181 shares (2,614,916 shares before the Reverse Split) of the Company’s common stock. Additionally, the Company issued an aggregate of 525,706 restricted shares (7,802,639 restricted shares before the Reverse Split) of its common stock or rights to receive the Company’s common stock, to certain advisers. On the same day and in connection with the Merger, the Company changed its name from StemCells, Inc. to Microbot Medical Inc. On November 29, 2016, the Company’s common stock began trading on the Nasdaq Capital Market under the symbol “MBOT”.

As a result of the Merger, Microbot Israel became a wholly owned subsidiary of the Company. The transaction between the Company and Microbot Israel was accounted for as a reverse recapitalization. As the shareholders of Microbot Israel received the largest ownership interest in the Company, Microbot Israel was determined to be the “accounting acquirer” in the reverse recapitalization. As a result, the historical financial statements of the Company were replaced with the historical financial statements of Microbot Israel. Unless indicated otherwise, pre-acquisition share, options and warrants data included in these financial statements is retroactively adjusted to reflect the Reverse Stock Split and the Merger.

Prior to the Merger, the Company was a biopharmaceutical company that conducts research, development, and commercialization of stem cell therapeutics and related technologies. Substantially the sale of all material assets relating to the stem cell business were completed on November 29, 2016.

The Company and its subsidiaries are collectively referred to as the “Company”. “StemCells” or “StemCells, Inc.” refers to the Company prior to the Merger.

| F-8 |

| B. | Risk Factors:

To date, the Company has not generated revenues from its operations. As of the date of issuance of these financial statements, the Company has cash and cash equivalent balance of $9.5 million, 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. Due to continuing research and development activities, the Company expects to continue to incur net losses into the foreseeable future. The Company plans to continue to fund its current operations as well as other development activities relating to additional product candidates, through future issuances of either debt and/or equity securities and possibly additional grants from the Israeli Innovation Authority. The Company’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’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.

| C. | Use of estimates:

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions pertaining to transactions and matters whose ultimate effect on the financial statements cannot precisely be determined at the time of financial statements preparation. Although these estimates are based on management’s best judgment, actual results may differ from these estimates.

| D. | Reverse Stock Split

On September 4, 2018, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to affect a one-for-15 reverse stock split of the Company’s common stock (the “Reverse Split”). As a result of the Reverse Split, every 15 shares of the Company’s old common stock will be converted into one share of the Company’s new common stock. Fractional shares resulting from the Reverse Split will be rounded up to the nearest whole number. The Reverse Split automatically and proportionately adjusted, based on the one-for-fifteen split ratio, all issued and outstanding shares of the Company’s common stock, as well as common stock underlying convertible preferred stock, stock options, warrants and other derivative securities outstanding at the time of the effectiveness of the reverse stock split. The exercise price on outstanding equity based-grants was proportionately increased, while the number of shares available under the Company’s equity-based plans was also proportionately reduced. Share and per share data (except par value) for the periods presented reflect the effects of this Reverse Split. References to numbers of shares of common stock and per share data in the accompanying financial statements and notes thereto have been adjusted to reflect the Reverse Split on a retroactive basis.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies applied in the preparation of the financial statements are as follows:

| A. | Basis of presentation:

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”).

| B. | Financial statement in U.S. dollars:

The functional currency of the Company is the U.S. dollar (“dollar”) since the dollar is the currency of the primary economic environment in which the Company has operated and expects to continue to operate in the foreseeable future.

Transactions and balances denominated in dollars are presented at their original amounts. Transactions and balances denominated in foreign currencies have been re-measured to dollars in accordance with the provisions of ASC 830-10, “Foreign Currency Translation”.

All transaction gains and losses from re-measurement of monetary balance sheet items denominated in non-dollar currencies are reflected in the statement of operations as financial income or expenses, as appropriate.

| F-9 |

| C. | Cash and cash equivalents:

Cash and cash equivalents consist of cash and demand deposits in banks, and other short-term liquid investments (primarily interest-bearing time deposits) with original maturities of less than three months.

| D. | Fair value of financial instruments:

The carrying values of cash and cash equivalents, other receivable and other accounts payable and accrued liabilities approximate their fair value due to the short-term maturity of these instruments.

The Company measures the fair value of certain of its financial instruments (such as the derivative warrant liabilities) on a recurring basis. The method of determining the fair value of derivative warrant liabilities is discussed in Note 8.

A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets and liabilities.

Level 2 - 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.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

| E. | Fixed assets:

Fixed assets are presented at costs less accumulated depreciation. Depreciation is calculated based on the straight-line method over the estimated useful lives of the assets, as the following annual rates:

|  | % |
Research equipment and software |  |  | 25-33 |
Furniture and office equipment |  |  | 7 |

| F. | Liabilities due to termination of employment agreements

Under Israeli employment laws, employees of Microbot Israel are included under Article 14 of the Severance Compensation Act, 1963 (“Article 14”). According to Article 14, these employees are entitled to monthly deposits made by Microbot Israel on their behalf with insurance companies.

Payments in accordance with Article 14 release Microbot Israel from any future severance payments (under the Israeli Severance Compensation Act, 1963) with respect of those employees. The aforementioned deposits are not recorded as an asset in the Company’s balance sheet,

| G. | Basic and diluted net loss per share

Basic net loss per share is computed by dividing net loss, as adjusted to include s by the weighted average number of common shares outstanding during the year. Common shares and preferred shares contingently issuable for little or no cash are included in basic net loss per share on an as issued basis.

| F-10 |

Diluted net loss per share is computed by dividing net loss, as adjusted to include preferred shares dividend participation rights of preferred shares outstanding during the year as well as of preferred shares that would have been outstanding if all potentially dilutive preferred shares had been issued, by the weighted average number of common shares outstanding during the year, plus the number of common shares that would have been outstanding if all potentially dilutive common shares had been issued, using the treasury stock method, in accordance with ASC 260-10 “Earnings per Share”.

All outstanding stock options and warrants have been excluded from the calculation of the diluted loss per share for the years ended December 31, 2017 and December 31, 2016, since all such securities have an anti-dilutive effect.

The weighted average number of shares outstanding has been retroactively restated for the equivalent number of shares received by the accounting acquirer as a result of the reverse recapitalization as if these shares had been outstanding as of the beginning of the earliest period presented.

| H. | Research and development expenses, net:

Research and development expenses are charged to the statement of operations as incurred. Grants for funding of approved research and development projects are recognized at the time the Company is entitled to such grants, on the basis of the costs incurred and applied as a deduction from the research and development expenses.

| I. | Convertible Notes:

Proceeds from the sale of debt securities with a conversion feature are allocated to equity based on the intrinsic value of such conversion feature in accordance with ASC 470-20 “Debt with Conversion and Other Options”, with a corresponding discount on the debt instrument recorded in liabilities which is amortized in finance expense over the term of the notes.

Convertible notes with characteristics of both liabilities and equity are classified as either debt or equity based on the characteristics of its monetary value, with convertible notes classified as debt being measured at fair value, in accordance with ASC 480-10, “Accounting for Certain Financial instruments with Characteristics of both Liabilities and Equity”.

| J. | Share-based compensation:

The Company applies ASC 718-10, “Share-Based Payment,” which requires the measurement and recognition of compensation expenses for all share-based payment awards made to employees and directors including stock options under the Company’s stock plans based on estimated fair values.

ASC 718-10 requires companies to estimate the fair value of stock options using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company’s statement of operations.

The Company accounts for stock-based compensation awards to non-employees in accordance with FASB ASC 505-50, “Equity-Based Payments to Non-Employees” (“FASB ASC 505-50”). Under FASB ASC 505-50, the Company determines the fair value of the warrants or stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable.

The Company estimates the fair value of stock options granted as share-based payment awards using a Black-Scholes options pricing model. The option-pricing model requires a number of assumptions, of which the most significant are expected volatility and the expected option term (the time from the grant date until the options are exercised or expire). Expected volatility is estimated based on volatility of similar companies in the technology sector for equity awards granted prior to the Merger and on the Company’s trading share price for equity awards granted subsequent to the Merger. The Company has historically not paid dividends and has no foreseeable plans to issue dividends. The risk-free interest rate is based on the yield from governmental zero-coupon bonds with an equivalent term. The expected stock option term is calculated for stock options granted to employees and directors using the “simplified” method. Grants to non-employees are based on the contractual term. Changes in the determination of each of the inputs can affect the fair value of the stock options granted and the results of operations of the Company.

| F-11 |

| K. | Reclassification:

Certain prior year amounts have been reclassified to conform to the current year presentation.

| L. | Transaction Costs

Transaction costs incurred in the Merger were charged directly to equity to the extent of cash and net other current assets acquired. Transaction costs in excess of cash acquired were charged to general and administrative expenses.

| M. | Income Taxes

The Company provides for income taxes using the asset and liability approach. Deferred tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities and the tax rates in effect when these differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 31, 2017, and 2016, the Company had a full valuation allowance against deferred tax assets.

| N. | Recent Accounting Standards:

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” to provide a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The ASU supersedes most current revenue recognition guidance, including industry-specific guidance. The FASB subsequently issued ASU 2015-14, ASU 2016-08 and ASU 2016-12, which clarified the guidance, provided scope improvements and amended the effective date of ASU 2014-09. As a result, ASU 2014-09 becomes effective for the Company in the first quarter of 2018, with early adoption permitted. The Company has not yet generated revenues to date, and does not yet know the impact the standard may have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02 “Leases” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. For operating leases, the ASU requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The ASU retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. This ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company continues to evaluate the effect of the adoption of this ASU and expects the adoption will result in an increase in the assets and liabilities on the consolidated balance sheets for operating leases (refer to Note 9) and will likely have an insignificant impact on the consolidated statements of comprehensive loss.

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments – Credit Losses” to improve information on credit losses for financial assets and net investment in leases that are not accounted for at fair value through net income. The ASU replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. This ASU is effective for the Company in the first quarter of 2020, with early adoption permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements.

| F-12 |

In November 2016, the FASB issued ASU 2016-18 “Restricted Cash” to provide guidance on the presentation of restricted cash in the statement of cash flows. Currently, the statement of cash flows explained the change in cash and cash equivalents for the period. The ASU requires that the statement of cash flows explain the change in cash, cash equivalents and restricted cash for the period. The ASU is effective for the Company in the first quarter of 2018, with early adoption permitted. The Company does not expect the adoption to have a material effect on the statements of cash flows as the Company’s restricted cash is not expected to be material.

In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-09, “Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting,” which clarifies when a change to terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance requires modification accounting if the vesting condition, fair value or the award classification is not the same both before and after a change to the terms and conditions of the award. The new guidance is effective for the Company on a prospective basis beginning on January 1, 2018 and early adoption is permitted. The Company does not expect to change terms or conditions of share-based payment awards, and therefore, does not expect the adoption of this standard to have a material impact on its consolidated financial statements.

In July 2017, the FASB issued ASU 2017-11, which includes Part I “Accounting for Certain Financial Instruments with Down Round Features” and Part II “Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-Controlling Interests with a Scope Exception”. The ASU makes limited changes to the Board’s guidance on classifying certain financial instruments as either liabilities or equity. The ASU’s objective is to improve (1) the accounting for instruments with “down-round” provisions and (2) the readability of the guidance in ASC 480 on distinguishing liabilities from equity by replacing the indefinite deferral of certain pending content with scope exceptions. The ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company has derivative warranty liabilities as discussed in Note 8 which upon adoption of the new standard are expected to be classified as equity.

(*) Purchase Agreement with BOCO

On November 11, 2016, the Company, together with two of its wholly-owned subsidiaries, Stem Cell Sciences Holdings Limited and StemCells California, Inc. (collectively, with the Company, the “Sellers”), entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with BOCO Silicon Valley, Inc., a California corporation and wholly-owned subsidiary of Bright Oceans Corporation (“BOCO US”).

Pursuant to the terms and subject to the conditions set forth in the Asset Purchase Agreement, the Sellers sold to BOCO US certain stem and progenitor cell lines that have been researched, studied or manufactured by the Company since 2007 (the “Cell Lines”) and certain other tangible and intangible assets, including intellectual property and books and records, related to the foregoing (together with the Cell Lines, the “Assets”) in exchange for $4 million in cash (the “Asset Consideration”).

| F-13 |

Of the Asset Consideration, $300 was provided to the Company prior to November 11, 2016 in exchange for the Sellers’ agreement not to solicit or reach any agreement with any third party pertaining to the sale of the Assets, and $400 will remain in a twelve-month escrow for the benefit of BOCO US to satisfy certain indemnification obligations of the Sellers which may arise and which, subject to any valid indemnification claims of BOCO US, will be released to the Company at the end of such 12-month period. In addition, sixteen former employees of the Company received, in the aggregate, $495 in accordance with their June 2016 agreements with the Company under which each accepted a more than 50% reduction in his or her severance award otherwise payable.

The Asset Purchase Agreement contains certain covenants prohibiting the Sellers from, during the four-year period immediately following the completion of the Asset Sale, (a) engaging in or having certain financial interests in a business that is engaged in the research, development or commercialization of the Cell Lines, or (b) soliciting for employment employees of BOCO US.

On November 29, 2016, the Sellers completed the sale of the Assets.

As of December 31, 2017, the Company received $320 from the escrow account and paid $80 to certain consultant relating to BOCO transaction.

The opening balance sheet as of the Merger date included a receivable balance with respect to sale of the Assets of $3.5 which fully collected as of December 31 2017.

NOTE 6 - CONVERTIBLE LOAN FROM SHAREHOLDERS

On October 8, 2015, Microbot Israel entered into a convertible loan agreement with several investors who were also existing shareholders. According to the loan agreement, Microbot Israel received an amount of $419. The loan bore interest of 10% and was converted to both equity shares and preferred shares warrants of Microbot Israel on the nine-month anniversary of the loan. The Company concluded the conversion feature is not a Beneficial Conversion Feature pursuant to the provisions of ASC 470-20, “Debt with Conversion and Other Options”. Accordingly, the proceeds were recorded in liabilities in their entirety at the date of issuance.

On July 7, 2016, the outstanding principal and accrued interest were converted into 1,315,023 Series A preferred shares, of Microbot Israel (the “Series A Preferred Shares”) and 1,188,275 warrants to purchase the Series A Preferred Shares, at an exercise price of $1.00 per share. The preferred shares warrants were exercised in full in September 2016 for total gross proceeds to Microbot Israel of $410.

On May 11, 2016, Microbot Israel entered into a convertible loan agreement with several investors who were also existing shareholders. The loan bore interest at a fixed rate of 10% per annum beginning on the issuance date.

At maturity, all of the outstanding principal and accrued interest was converted into Microbot Israel’s ordinary shares subject to the conversion or default events specified in the loan agreement, based on a conversion price that represents a 20% discount on Microbot Israel’s valuation upon such default events.

On November 28, 2016, upon the consummation of the Merger, the loan was converted into an aggregate of 151,119 shares (2,242,939 shares before the Reverse Split) of Company’s common stock.

The Company concluded the value of the loan is predominantly based on a fixed monetary amount known at the date of issuance as represented by the 20% discount on the Company’s valuation. Accordingly, the loan was classified as debt and was measured at its fair value, pursuant to the provisions of ASC 480-10, “Accounting for Certain Financial instruments with Characteristics of both Liabilities and Equity”.

The fair value of the loan was measured based on observable inputs as the fixed monetary value of the variable number of shares to be issued upon conversion (level 2 measurement).

Secured note to Alpha Capital Anstalt:

On August 15, 2016, concurrent with the execution of the Agreement and Plan of Merger (see Note 1A), StemCells Inc. issued a 6.0% secured note (the “Note”) to Alpha Capital Anstalt (“Alpha Capital”), in the principal amount of $2,000, for value received, payable upon the earlier of (i) 30 days following the consummation of the Merger and (ii) December 31, 2016. Proceeds from the Note were used for the payment of costs and expenses in connection with the Merger and operational expenses leading to such Closing.

The Note bears interest at 6% per annum, payable monthly in arrears on the first of the month, beginning on January 1, 2017 until the principal amount is paid in full. In addition, the Note is secured by a first priority security interest in all of the Company’s intellectual property and certain other general assets pursuant to a Security Agreement

Securities Exchange Agreement with Alpha Capital:

As of the effective time of the Merger, the Company entered into a Securities Exchange Agreement (the “Exchange Agreement”) with Alpha Capital, providing for the issuance to Alpha Capital of a convertible promissory note by the Company (the “Convertible Note”) in a principal amount of $2,029, which is equal to the principal and accrued interest under the Note, in exchange for (a) the full satisfaction, termination and cancellation of the Note and (b) the release and termination of the Security Agreement and the first priority security interest granted thereunder.

The Convertible Note was convertible into the Company’s Common Stock any time after November 28, 2017 and until the maturity date of November 28, 2019, based on a conversion price of $9.60 ($0.64 before the Reverse Split), subject to adjustments as provided in the Exchange Agreement.

| F-15 |

Pursuant to the terms of the Convertible Note, the Company was obligated to pay interest on the outstanding principal amount owed under the Convertible Note at a fixed rate per annum of 6.0%, payable at maturity or earlier upon conversion. The Exchange Agreement contains customary representations and warranties and usual and customary affirmative and negative covenants. The Convertible Note also contained certain customary events of default.

As the Exchange Agreement represented the consummation of the original intent of the Company and Alpha Capital, as of the date of execution of the Merger Agreement (August 2016), to enter into a $2 million convertible note sale transaction, upon the consummation of the Merger, the Company accounted for the convertible note in accordance with such economic substance, as if it had been issued for a cash consideration equal to the principal and accrued interest on the Note, as of the effective date of the Merger, in the amount of $2,029 (the “Assumed Consideration”), which is equal to the principal amount of the Convertible Note as determined in the Exchange Agreement.

The Company concluded the conversion feature of the Convertible Note, based on the commitment date of November 28 2016 (the Exchange Agreement date), is a Beneficial Conversion Feature pursuant to the provisions of ASC 470-20, “Debt with Conversion and Other Options”. Accordingly, $2,029 of the Assumed Consideration was recorded in equity with a corresponding discount on the Convertible Note, to be amortized over its term through maturity.

See also Note 10 – Securities Exchange Agreements with Alpha Capital.

The carrying value of the Convertible Note as of the periods below was calculated as follow:

NOTE 7 - DERIVATIVE WARRANT LIABILITIES

As part of StemCell’s obligations under the Merger Agreement, in August 2016, StemCells negotiated with certain institutional holders of its 2016 Series A and Series B Warrants, issued by prior to the Merger, to have such holders surrender their 2016 Series B Warrants in exchange for a reduced exercise price of $4.45 ($0.30 before the Reverse Split) per share on their existing 2016 Series A Warrants and the elimination of the anti-dilution price protection in the 2016 Series A Warrants. As a result, the exercise price for all outstanding 2011 Series A Warrants and 2016 Series A and Series B Warrants was reset to of $4.45 ($0.30 before the Reverse Split) per share. Subsequent to the reset of the exercise price, an aggregate of 35,831 (531,814 before the Reverse Split) (from an outstanding aggregate of 38,948 (578,081 before the Reverse Split)) 2011 Series A Warrants were exercised. For the exercise of these warrants, the Company issued 35,831 shares (531,814 shares before the Reverse Split) of its common stock prior to the Merger.

| (*) | December 31 2017 and 2016 warrants data represents the number of shares adjusted to retroactively reflect the 1:15 Reverse Split effected on September 4, 2018.
| a) | These warrants contain a full ratchet anti-dilution price protection so that, in most situations upon the issuance of any common stock or securities convertible into common stock at a price below the then-existing exercise price of the outstanding warrants, the warrant exercise price will be reset to the lower common stock sales price. As such anti-dilution price protection does not meet the specific conditions for equity classification, the Company is required to classify the fair value of these warrants as a liability, with changes in fair value to be recorded as income (loss) due to change in fair value of warrant liability. The estimated fair value of our warrant liability at December 31, 2017 and December 31, 2016, was approximately $28 and $313, respectively.

As quoted prices in active markets for identical or similar warrants are not available, the Company uses directly observable inputs in the valuation of its derivative warrant liabilities (level 2 measurement).

The Company uses the Black-Scholes valuation model to estimate fair value of these warrants. In using this model, the Company makes certain assumptions about risk-free interest rates, dividend yields, volatility, expected term of the warrants and other assumptions. Risk-free interest rates are derived from the yield on U.S. Treasury debt securities. Dividend yields are based on our historical dividend payments, which have been zero to date. Volatility is estimated from the historical volatility of our common stock as traded on NASDAQ. The expected term of the warrants is based on the time to expiration of the warrants from the date of measurement.

| b) | In March 2017, an institutional holder executed a cashless exercise of 51 warrants (768 before the Reverse Split) and 24 shares (359 shares before the Reverse Split) of Common Stock were issued in connection therewith.

In accordance with ASC-820-10-50-2(g), the Company has performed a sensitivity analysis of the derivative warrant liabilities of the Company which are classified as level 3 financial instruments. The Company recalculated the value of warrants by applying a +/- 5% changes to the input variables in the Black-Scholes model that vary overtime, namely, the volatility and the risk-free rate. A 5.0% decrease in volatility would decrease the value of the warrants to $27; a 5.0% increase in volatility would increase the value of the warrants to $29. A 5.0% decrease or increase in the risk-free rate would not have materially changed the value of the warrants; the value of the warrants is not strongly correlated with small changes in interest rates.

NOTE 8 - COMMITMENTS AND CONTIGENCIES

Microbot Israel obtained from the Israeli Innovation Authority (“IIA”) grants for participation in research and development for the years 2013 through December 31, 2017 in the total amount of approximately $1,183 and, in return, Microbot Israel is obligated to pay royalties amounting to 3% of its future sales up to the amount of the grant. The grant is linked to the exchange rate of the dollar to the New Israeli Shekel and bears interest of Libor per annum.

The repayment of the grants is contingent upon the successful completion of the Company’s research and development programs and generating sales. The Company has no obligation to repay these grants, if the project fails, is unsuccessful or aborted or if no sales are generated. The financial risk is assumed completely by the Government of Israel. The grants are received from the Government on a project-by-project basis.

| F-18 |

Microbot Israel signed an agreement with the Technion Research and Development Foundation (“TRDF”) in June 2012 by which TRDF transferred to Microbot Israel a global, exclusive, royalty-bearing license. As partial consideration for the license, Microbot Israel shall pay TRDF royalties on net sales (between 1.5%-3%) and on sublicense income as detailed in the agreement.

Lease Agreements:

In June 2016, the Company entered into an office lease agreement, with a term ending on February 28, 2018. According to the lease agreement, the monthly office lease payment is approximately $3.

In December 2016, the Company entered into a cars lease agreement, which will end on December 31, 2019. According to the lease agreement, the monthly car lease payment is approximately $2.5.

In May 2017, the Company entered into an office lease agreement effective from February 1, 2018, with a term ending on December 31, 2020. According to the lease agreement, the monthly office lease payment is approximately $14

Compensation liability

The Company incurred compensation commitments of approximately $400 to a former executive that management estimates as remote that this amount will ever be paid out and therefore is not reflected in these consolidated financial statements.

Contract Research Agreement

On January 27, 2017, the Company entered into a Contract Research Agreement (the “Research Agreement”) with The Washington University (“Washington U.”), pursuant to which the parties will collaborate to determine the effectiveness of the Company’s self-cleaning shunt.

The study in WU includes several phases. The first phase (initial research) was completed. The parties are in the final stage of planning the next phase, including the related various costs. 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.

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, pending in the Supreme Court of the State of New York, County of New York. The complaint alleges, 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 seeks 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 million. The parties presently are engaged in discovery.

Management is unable to assess the likelihood of the claim and the amount of potential damages, if any, to be awarded. Management believes that the claims made against it are without merit and intends to vigorously defend itself against these claims.

NOTE 9 - SHARE CAPITAL

Each share of the Series A Convertible Preferred Stock, par value $0.01 per share, issued by the Company in December 2016 and in May 2017 (the “Series A Convertible Preferred Stock”), is convertible, at the option of the holder, into 67 shares ( 1,000 shares before the Reverse Split) of Common Stock, and confer upon the holder dividend rights on an as converted basis.

Exercise of Warrants

On March 2017, an institutional holder exercised, in a cashless transaction, of 52 warrants ( 768 before the Reverse Split) and 24 shares ( 359 shares before the Reverse Split) of Common Stock were issued in connection therewith.

Share capital developments:

The authorized capital stock consists of 221,000,000 shares of capital stock, which consists of 220,000,000 shares of Common Stock and 1,000,000 shares of undesignated preferred stock, par value $0.01 (the “Preferred Stock”). As of December 31, 2017, the Company had 2,734,300 shares (40,583,127 shares before the Reverse Split) of Common Stock issued and outstanding, and 4,001 shares of Series A Convertible Preferred Stock issued and outstanding.

On November 28, 2016, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to (i) effect the Reverse Stock Split, (ii) change its name from “StemCells, Inc.” to “Microbot Medical Inc.” and (iii) increase the number of authorized shares of the Common Stock from 200,000,000 to 220,000,000 shares (the “Certificate of Amendment”).

As a result of the Reverse Stock Split, the number of issued and outstanding shares of the Common Stock immediately prior to the Reverse Stock Split were reduced into a smaller number of shares, such that every nine shares of the Common Stock held by a stockholder immediately prior to the Reverse Stock Split were combined and reclassified into one share of the Common Stock.

Immediately following the Reverse Stock Split and the Merger, there were 2,442,646 shares (36,254,240 shares before the Reverse Split) of the Common Stock issued and outstanding, which included certain rights to receive shares of Common Stock or equivalent securities but excludes shares underlying outstanding stock options and warrants and the Convertible Note.

On December 27, 2016, the Company exchanged 655,962 shares (9,735,925 shares before the Reverse Split) or rights to acquire shares of its Common Stock, for 9,736 shares of a newly designated class of Series A Convertible Preferred Stock. See “- Securities Exchange Agreement with Alpha Capital” below. See also Note 6 – Securities Exchange Agreement with Alpha Capital, above.

Shares issued to service provider

In connection with the Merger, the Company issued an aggregate of 525,706 restricted shares (7,802,639 restricted shares before the Reverse Split) of its Common Stock to certain advisors. The fair value of the award of approximately $10,000 was estimated based on the share price of the Common Stock of $19.2 ($1.28 before the Reverse Split) as of the date of grant. The portion of the expense in excess of the cash and other current assets acquired in the Merger, in the amount of $7,300 was included in general and administrative expenses in the Statements of Comprehensive Loss.

During 2017 the Company issued an aggregate of 8, 085 nonrefundable shares (120,000 nonrefundable shares before the Reverse Split) of Common Stock to a consultant as part of investor relations services. The Company recorded expenses of approximately $225 with respect to the issuance of these shares included in general and administrative expenses.

Securities Exchange Agreement with Alpha Capital

On December 16, 2016, the Company entered into a Securities Exchange Agreement with Alpha Capital, pursuant to which Alpha Capital exchanged 655,967 shares (9,736,000 shares before the Reverse Split) of common stock or rights to acquire shares of the common stock held by it, for 9,736 shares of a newly designated class of Series A Convertible Preferred Stock, par value $0.01 per share (the “Preferred Stock”). The common stock and common stock underlying the rights to acquire common stock include all of the shares of common stock issued or issuable to Alpha Capital pursuant to the Merger. The 655,967 shares (9,735,925 shares before the Reverse Split) of common stock and the rights to acquire common stock were cancelled and the Company’s issued and outstanding shares of Common Stock were reduced to 1,786,684 (26,518,315 before the Reverse Split).

| F-23 |

On May 9, 2017, the Company entered into a Securities Exchange Agreement with Alpha Capital pursuant to which the Company agreed to issue 3,254 shares of the Series A Convertible Preferred Stock, in exchange for the full satisfaction, termination and cancellation of the outstanding 6% convertible promissory note of the Company in the principal amount of approximately $2,029 issued on November 28, 2016 and held by Alpha Capital. The Series A Convertible Preferred Stock is the same series of securities as the Company’s existing Series A Convertible Preferred Stock issued in December 2016. As a result of the extinguishment of the convertible note and issuance of the preferred shares, the Company recorded a financial loss in the amount of $2,360.

During the year 2017, the holder of the Series A Convertible Preferred Stock converted 8,990 shares of the Series A Convertible Preferred Stock for 605,705 shares (8,990,000 shares before the Reverse Split) of Common Stock, pursuant to the terms of conversion of the Series A Convertible Preferred Stock.

Repurchase of Shares

The Company intends to enter into a definitive agreement with up to three Israeli shareholders, some of whom are directors of the Company, that were former shareholders of Microbot Israel, pursuant to which the Company would repurchase, at a discount on the fair value of the share at the date of repurchase, up to $500 of Common Stock held by them, in the aggregate, if and to the extent such shareholders are unable to sell enough of their shares to cover certain of their Israeli tax liabilities resulting from the Merger. Such repurchase(s), if any, would occur only after the two-year anniversary of the Merger. The transaction is subject to negotiating final terms and entering into definitive agreements with such shareholders.

The Company evaluated whether an embedded derivative that requires bifurcation exists within such shares that may be subject to repurchase. The Company concluded the fair value of such derivative instrument would be nominal and, in any case, would represent an asset to the Company as (a) the settlement requires acquiring the shares at a discount on the fair market value of the share at the time of re purchase and in no circumstances the acquisition price will be higher than approximately one dollar per share (representing 25% discount on the fair market value of the share at the merger closing date) and (b) it is assumed that the selling shareholders would use such right as last resort as such repurchase at a discount on the fair market value of such shares results in a loss to be incurred by the selling shareholders.

In accordance with ASC 480-10-S99-3A (formerly EITF D-98), the Company classified the maximum amount it may be required to pay in the event the repurchase right is exercised ($500) as temporary equity.

NOTE 10 - BASIC AND DILUTED NET LOSS PER SHARE

(*) December 31 2017 and 2016 shares data represents the number of shares adjusted to retroactively reflect the 1:15 Reverse Split effected on September 4, 2018.

| F-24 |

As the inclusion of common share equivalents in the calculation would be anti-dilutive for all periods presented, diluted net loss per share is the same as basic net loss per share.

The weighted average number of common shares outstanding has been retroactively restated for the equivalent number of common shares received by the accounting acquirer as a result of the reverse recapitalization and reverse stock split as if these common shares had been outstanding as of the beginning of the earliest period presented.

NOTE 15 - TAXES ON INCOME

The Company is subject to income taxes under the Israeli and U.S. tax laws:

Corporate tax rates

The Company is subject to Israeli corporate tax rate of 25% in the year 2016, 24% in 2017 and 23% from 2018. The Company is subject to a blended U.S. tax rate (Federal as well as state corporate tax) of 35%.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was signed into law in the United States. The Tax Act, among other provisions, introduces changes in the U.S corporate tax rate, business related exclusions and deductions and credits, and has internationally tax consequences for companies that operate international. Most of the changes introduced in the Tax Act are effective beginning on January 1, 2018. The Tax Act introduces a reduced federal tax rate of 21% from January 1, 2018 and onward.

| F-26 |

| A. | As of December 31, 2017, the Company generated net operating losses in Israel of approximately $5,267 which may be carried forward and offset against taxable income in the future for an indefinite period.

As of December 31, 2017, the Company generated net operating losses in the U.S. of approximately $2,987. Net operating losses in the United States are available through 2035. Utilization of U.S. net operating losses may be subject to substantial annual limitation due to the “change in ownership” provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of net operating losses before utilization.

| B. | The Company is still in its development stage and has not yet generated revenues, therefore, it is more likely than not that sufficient taxable income will not be available for the tax losses to be utilized in the future. Therefore, a valuation allowance was recorded to reduce the deferred tax assets to its recoverable amounts.

|  | As of December 31, |
|  | 2017 |  |  | 2016 |
Net operating loss carry-forward |  | $ | 488,603 |  |  | $ | 481,052 |
Total deferred tax assets |  |  | 117,265 |  |  |  | 120,263 |

NOTE 1 - GENERAL

| A. | Description of Business

Microbot Medical Inc. (the “Company”) is a pre-clinical medical device company specializing in the research, design and development of next generation micro-robotics assisted medical technologies targeting the minimally invasive surgery space. The Company is primarily focused on leveraging its micro-robotic technologies with the goal of improving surgical outcomes for patients.

It was incorporated on August 2, 1988 in the State of Delaware under the name Cellular Transplants, Inc. The original Certificate of Incorporation was restated on February 14, 1992 to change the name of the Company to Cyto Therapeutics, Inc. On May 24, 2000, the Certificate of Incorporation as restated was further amended to change the name of the Company to StemCells, Inc.

On November 28, 2016, the Company consummated a transaction pursuant to an Agreement and Plan of Merger, dated August 15, 2016, with Microbot Medical Ltd., a private medical device company organized under the laws of the State of Israel (“Microbot Israel”). On the same day and in connection with the Merger, the Company changed its name from StemCells, Inc. to Microbot Medical Inc. On November 29, 2016, the Company’s common stock began trading on the Nasdaq Capital Market under the symbol “MBOT”.

Prior to the Merger, the Company was a biopharmaceutical company that conducted research, development, and commercialization of stem cell therapeutics and related technologies. The sale of substantially all material assets relating to the stem cell business were completed on November 29, 2016.

The Company and its subsidiaries are collectively referred to as the “Company”. “StemCells” or “StemCells, Inc.” refers to the Company prior to the Merger.

| B. | Risk Factors

To date, the Company has not generated revenues from its operations. As of September 30, 2018, the Company had cash and cash equivalent balance of approximately $6,673, 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. Due to continuing research and development activities, the Company expects to continue to incur net losses into the foreseeable future. The Company plans to continue to fund its current operations as well as other development activities relating to additional product candidates, through future issuances of either debt and/or equity securities and possibly additional grants from the Israeli Innovation Authority and others. The Company’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’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.

| C. | Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions pertaining to transactions and matters whose ultimate effect on the financial statements cannot precisely be determined at the time of financial statements preparation. Although these estimates are based on management’s best judgment, actual results may differ from these estimates.

| F-33 |

| D. | Reverse Stock Split

On September 4, 2018, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to affect a one-for-15 reverse stock split of the Company’s common stock (the “Reverse Split”). As a result of the Reverse Split, every 15 shares of the Company’s old common stock was converted into one share of the Company’s new common stock. Fractional shares resulting from the Reverse Split were rounded up to the nearest whole number. The Reverse Split automatically and proportionately adjusted, based on the one-for-fifteen split ratio, all issued and outstanding shares of the Company’s common stock, as well as common stock underlying convertible preferred stock, stock options, warrants and other derivative securities outstanding at the time of the effectiveness of the Reverse Split. The exercise price on outstanding equity based-grants was proportionately increased, while the number of shares available under the Company’s equity-based plans was also proportionately reduced. Share and per share data (except par value) for the periods presented reflect the effects of the Reverse Split. References to numbers of shares of common stock and per share data in the accompanying financial statements and notes thereto for periods ended prior to September 4, 2018 have been adjusted to reflect the Reverse Split on a retroactive basis.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies applied in the preparation of the financial statements are as follows:

Unaudited Interim Financial Statements

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of U.S. Securities and Exchange Commission (“SEC”) regulations. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included (consisting only of normal recurring adjustments except as otherwise discussed).

Operating results for the nine-month period ended September 30, 2018, are not necessarily indicative of the results that may be expected for the year ended December 31, 2018.

Significant Accounting Policies

The significant accounting policies followed in the preparation of these unaudited interim condensed consolidated financial statements are identical to those applied in the preparation of the latest annual audited financial statements.

Recent Accounting Standards

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” to provide a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The ASU supersedes most current revenue recognition guidance, including industry-specific guidance. The FASB subsequently issued ASU 2015-14, ASU 2016-08 and ASU 2016-12, which clarified the guidance, provided scope improvements and amended the effective date of ASU 2014-09. As a result, ASU 2014-09 becomes effective for the Company in the first quarter of 2018, with early adoption permitted. The adoption of this standard did not have a material impact on our interim consolidated statements of comprehensive loss since the Company has not yet generated revenues to date.

In June 2018, the FASB issued ASU No. 2018-07 “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation - Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-Employees. The guidance is effective for the Company during the first quarter of 2019. The Company is assessing ASU 2018-07 and does not expect it to have a material impact on its consolidated financial statements.

| F-34 |

In February 2016, the FASB issued ASU 2016-02 “Leases” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. For operating leases, the ASU requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, on its balance sheet. The ASU retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee.

In July 2018, the FASB issued ASU No. 2018-11, “Targeted Improvements - Leases (Topic 842).” This update provides an optional transition method that allows entities to elect to apply the standard prospectively at its effective date, versus recasting the prior periods presented. If elected, an entity would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. This ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company continues to evaluate the effect of the adoption of this ASU and expects the adoption will result in an increase in the assets and liabilities on the consolidated balance sheets for operating leases (refer to Note 4) and will likely have an insignificant impact on the consolidated statements of comprehensive loss.

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments – Credit Losses” to improve information on credit losses for financial assets and net investment in leases that are not accounted for at fair value through net income. The ASU replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. This ASU is effective for the Company in the first quarter of 2020, with early adoption permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements.

In July 2017, the FASB issued ASU 2017-11, which includes Part I “Accounting for Certain Financial Instruments with Down Round Features” and Part II “Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-Controlling Interests with a Scope Exception”. The ASU makes limited changes to the Board’s guidance on classifying certain financial instruments as either liabilities or equity. The ASU’s objective is to improve (1) the accounting for instruments with “down-round” provisions and (2) the readability of the guidance in ASC 480 on distinguishing liabilities from equity by replacing the indefinite deferral of certain pending content with scope exceptions. The ASU is effective for the Company in the first quarter of 2019, with early adoption permitted. The Company has derivative warranty liabilities as discussed in Note 4 which upon adoption of the new standard are expected to be classified as equity.

NOTE 3 - DERIVATIVE WARRANT LIABILITIES

The remaining outstanding warrants and terms as of September 30, 2018 and December 31, 2017 after the split is as follows: (*)

Issuance date |  | Outstanding as of December 31, 2017 |  |  | Outstanding as of September 30, 2018 |  |  | Exercise Price |  |  | Exercisable as of September 30, 2018 |  |  | Exercisable Through

| (*) | December 31, 2017 warrants data represents the number of shares adjusted to retroactively reflect the 1:15 Reverse Split effected on September 4, 2018
| a) | These warrants contain a full ratchet anti-dilution price protection so that, in most situations upon the issuance of any common stock or securities convertible into common stock at a price below the then-existing exercise price of the outstanding warrants, the warrant exercise price will be reset to the lower common stock sales price. As such anti-dilution price protection does not meet the specific conditions for equity classification, the Company is required to classify the fair value of these warrants as a liability, with changes in fair value to be recorded as income (loss) due to change in fair value of warrant liability. The estimated fair value of our warrant liability at September 30, 2018 and December 31, 2017, was approximately $5 and $28, respectively.

| F-35 |

As quoted prices in active markets for identical or similar warrants are not available, the Company uses directly observable inputs in the valuation of its derivative warrant liabilities (level 3 measurement).

The Company uses the Black-Scholes valuation model to estimate fair value of these warrants. In using this model, the Company makes certain assumptions about risk-free interest rates, dividend yields, volatility, expected term of the warrants and other assumptions. Risk-free interest rates are derived from the yield on U.S. Treasury debt securities. Dividend yields are based on our historical dividend payments, which have been zero to date. Volatility is estimated from the historical volatility of our common stock as traded on NASDAQ. The expected term of the warrants is based on the time to expiration of the warrants from the date of measurement.

In March 2017, an institutional holder executed a cashless exercise of 51 warrants and 24 shares of Common Stock were issued in connection therewith.

The following table summarizes the observable inputs used in the valuation of the derivative warrant liabilities as of September 30, 2018 and December 31, 2017:

In accordance with ASC-820-10-50-2(g), the Company has performed a sensitivity analysis of the derivative warrant liabilities of the Company which are classified as level 3 financial instruments. The Company recalculated the value of warrants by applying a +/- 5% changes to the input variables in the Black-Scholes model that vary overtime, namely, the volatility and the risk-free rate. A 5.0% decrease or ‘increase in volatility would not have materially changed the value of the warrants. A 5.0% decrease or increase in the risk-free rate would not have materially changed the value of the warrants; the value of the warrants is not strongly correlated with small changes in interest rates.

NOTE 4 - COMMITMENTS AND CONTINGENCIES

Microbot Israel obtained from the Israeli Innovation Authority (“IIA”) grants for participation in research and development for the years 2013 through September 30, 2018 in the total amount of approximately $1,310 and, in return, Microbot Israel is obligated to pay royalties amounting to 3% of its future sales up to the amount of the grant.

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, pending in the Supreme Court of the State of New York, County of New York.

The complaint seeks 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 million.

Repurchase of Shares

The Company intends to enter into a definitive agreement with up to three Israeli shareholders, one of which is a director of the Company, that were former shareholders of Microbot Israel, pursuant to which the Company would repurchase, at a discount on the fair value of the share at the date of repurchase, up to $500 of Common Stock held by them, in the aggregate, if and to the extent such shareholders are unable to sell enough of their shares to cover certain of their Israeli tax liabilities resulting from the Merger. Such repurchase(s), if any, would occur only after the two-year anniversary of the Merger. The transaction is subject to negotiating final terms and entering into definitive agreements with such shareholders.

The Company evaluated whether an embedded derivative that requires bifurcation exists within such shares that may be subject to repurchase. The Company concluded the fair value of such derivative instrument would be nominal and, in any case, would represent an asset to the Company as (a) the settlement requires acquiring the shares at a discount on the fair market value of the share at the time of repurchase and in no circumstances the acquisition price will be higher than approximately one dollar per share (representing 25% discount on the fair market value of the share at the merger closing date) and (b) it is assumed that the selling shareholders would use such right as last resort as such repurchase at a discount on the fair market value of such shares results in a loss to be incurred by the selling shareholders.

In accordance with ASC 480-10-S99-3A (formerly EITF D-98), the Company classified the maximum amount it may be required to pay in the event the repurchase right is exercised ($500) as temporary equity.

Section 145 of the Delaware General Corporation Law (“DGCL”) permits, in general, a Delaware corporation, to indemnify any person who was or is a party to any proceeding (other than an action by, or in the right of, the corporation) by reason of the fact that or she is or was a director, or officer, of the corporation, or served another business enterprise in any capacity at the request of the corporation, against liability incurred in connection with such proceeding, including the expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such proceeding if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, in criminal actions or proceedings, additionally had no reasonable cause to believe that his or her conduct was unlawful. A Delaware corporation’s power to indemnify applies to actions brought by or in the right of the corporation, but only to the extent of expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of the action or suit, provided that no indemnification shall be provided in such actions in the event of any adjudication of negligence or misconduct in the performance of such person’s duties to the corporation, unless a court believes that in light of all the circumstances indemnification should apply. Section 145 of the DGCL also permits, in general, a Delaware corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation, or served another entity in any capacity at the request of the corporation, against liability incurred by such person in such capacity, whether or not the corporation would have the power to indemnify such person against such liability.

Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit.

The Company’s restated certificate of incorporation provides that the Company’s directors shall not be liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. The Company’s restated certificate of incorporation further provides that the Company shall indemnify its directors and officers to the fullest extent permitted by the DGCL.

We maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers. We believe that these indemnification provisions and insurance are necessary to attract and retain qualified directors and officers.

Item 17. Undertakings.

The undersigned Registrant hereby undertakes to provide to the underwriter at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each investor.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes:

| (1) | To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

| (i) | To include any prospectus required by Section 10(a)(3) of the Securities Act;
| (ii) | To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
| (iii) | To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

| (2) | That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
| (3) | To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
| (4) | That, for the purpose of determining liability under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

| (i) | Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424 (§230.424 of this chapter);
| (ii) | Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;
| (iii) | The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and
| (iv) | Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

| (5) | The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
| (6) | For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
| (7) | For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
