Overview

Our Company

Microbot is a pre-clinical medical device company specializing in the research, design and development effortsof 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 identification, isolationdevelopment of a Multi Generation Pipeline Portfolio utilizing all three of our proprietary technologies.

Microbot has a patent portfolio of 25 issued/allowed patents and expansion of stem cells15 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 underlyingability 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 CardioSertTMtechnology contemplates a combination of a guidewire and microcatheter, technologies that are broadly used for developingsurgery 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 CardioSertTMtechnology was originally developed to support interventional cardiologists in crossing chronic total occlusions (CTO) during percutaneous coronary intervention (PCI) procedures and has the potential cell transplant therapies. Stem cells are key cellsto 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 bodybrain that produce allcan 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 functional mature cell types foundbody where the fluid can be more readily absorbed. Hydrocephalus shunt designs have changed little since their introduction in normal, healthy individuals. Our goalthe 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 develop therapiesmaintain 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 will use stemresults 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 repopulateaccumulate in the brain or repair tissues,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 thosehardware, 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 pancreas or liver, that have been damaged or lostis 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 disease or injury. Allhead trauma, intracerebral hemorrhage, brain tumors and infection. The EVD serves to divert excess fluids from the brain and allows for the monitoring of our programs are currently at the discovery or pre-clinical stage. Many diseases,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 Alzheimer's, Parkinson's and other degenerative diseasesbleeding, is encountered. EVD is one of the brain or nervous system, involvemost commonly used and most important life-saving procedures in the failure of organs that cannot be transplanted. Other diseases,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 hepatitisblood 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 diabetes, involve organsreplacement, 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 liver or pancreas thatgeriatric 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 transplanted, but therestarted 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 very limited supplyCAGR of those organs available for transplant. We estimate based on information available23.9% between 2014-2020, to us fromreach a value over $350 million.

According to the Alzheimer's Association, the Centers for Disease Control, the Family Caregiver's Alliance and the Spinal Cord Injury Information Network, that these conditions affect more than 18Brain 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 more than $150 billion annually18.6% 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 health care costs. We believethe 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 our stem cell technologies, if successfully developed, may providetransmits the basis for effective therapies for thesemagnetic field at a pre-determined frequency and other conditions. Our aimoperating 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 return patients to productive livesactivate the cleaning mechanism within the proximal part of the ventricular catheter.

Microbot has completed the development of an SCS prototype and significantly reduceis currently completing the substantial health care costs often associated with these diseasessafety testing, general proof of concept testing and disorders. We have made significant progress toward developing stem cell therapiesperformance testing for the nervous system by identifying and characterizing the human central nervous system stem cell. We have also made significant advancesdevice, which Microbot began in our search for the stem cells of the pancreas and the liver by identifying novel markers on the surface of cells so they can be isolated and tested to determine whether they are stem cells. We have established our intellectual property position with respect to stem cell therapies for each of these three areas--the central nervous system, the pancreas and the liver--by patenting or seeking patent protection for our discoveries and by entering into exclusive licensing arrangements. Our portfolio of issued patents includes a method of culturing normal human neural stem cells in our proprietary medium, and our published studies show that our cultured and expanded cells give rise to all three major cell types of the central nervous system.mid-2013. In addition, the Company recentlyMay 2018, Microbot announced the results of two pre-clinical studies assessing the SCS, anin-vitro study and a newsmall 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 showedaims 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 bothin-vitro (lab) andin-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 brain stem cells canclinical 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 isolatedself-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 markers presentthe TipCAT for minimally invasive endovascular neurosurgical applications.

Corporate and Other Information

We were 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 our name to CytoTherapeutics, Inc. On May 24, 2000, the Certificate of Incorporation as restated was further amended to change our name to StemCells, Inc. On November 28, 2016, C&RD Israel Ltd., a wholly-owned subsidiary of ours, completed its merger with and into Microbot Medical Ltd., or Microbot Israel, an Israeli corporation that then owned our assets and operated our current business, with Microbot Israel surviving as a wholly-owned subsidiary of ours. We refer to this transaction as the Merger. On November 28, 2016, in connection with the Merger, we changed our name from “StemCells, Inc.” to Microbot Medical Inc., and each outstanding share of Microbot Israel capital stock was converted into the right to receive shares of our common stock. In addition, all outstanding options to purchase the ordinary shares of Microbot Israel were assumed by us and converted into options to purchase shares of the common stock of Microbot Medical Inc. On November 29, 2016, our common stock began trading on the surface of freshly obtained brain cells. We believe this isNasdaq Capital Market under the first reproducible process for isolating highly purified populations of well-characterized normal human neural stem cells, andsymbol “MBOT”. Prior to the Merger, we have applied forwere a composition of matter patent. We also have filed an improved process patent forbiopharmaceutical company that operated in one segment, the growth and expansion of these purified normal human neural cells. Historical Note: We were formerly known as CytoTherapeutics and were incorporated in Delaware in 1988. We currently have one subsidiary, StemCells California, Inc., a California corporation we acquired in September 1997. Until mid-1999, we had programs in a different technology, encapsulated cell therapy, as well as stem cell programs. In 1999, we embarked on a major restructuring of our research, and development operations and sold the encapsulated cell therapy technology. We now focus exclusively on the discovery, development, and commercialization of our proprietary platform of stem cell therapeutics and related technologies. 2 SUMMARY CONSOLIDATED FINANCIAL AND OTHER DATA (IN THOUSANDS, EXCEPT PER SHARE DATA)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 following table summarizesshare 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.

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:

ourability 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.

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.

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 dataposition. 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 business. You should read this table together with "Management'sstockholders, 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.

In July 1999 we began restructuring the company to focus solely on our stem cell technology. As part of this restructuring we terminated all activities related to our former encapsulated cell technologyprospectus and we relocated our headquarters from Lincoln, Rhode Island to Sunnyvale, California.

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 value related to our remaining holdingsfull) from the sale of $27,204,333 in connection with our investment in Modex Therapeutics Ltd., a Swiss biotechnology company that completed an initial public offering on June 23, 2000. For more information on Modex see "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements and notes included elsewherethe securities offered by us in this prospectus. 3 RISK FACTORS YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW BEFORE MAKING AN INVESTMENT DECISION REGARDING STEMCELLS, INC. WE MAY FACE OTHER RISKS NOT DESCRIBED BELOW THAT WE DO NOT PRESENTLY KNOW ABOUT OR THAT WE CURRENTLY DEEM IMMATERIAL. OUR BUSINESS, FINANCIAL CONDITION OR RESULTS OF OPERATIONS COULD BE MATERIALLY ADVERSELY AFFECTED BY ANY OF THESE RISKS. CONSEQUENTIALLY, THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE, RESULTING IN THE LOSS OF ALL OR PART OF YOUR INVESTMENT. OUR TECHNOLOGY IS AT AN EARLY STAGE OF DISCOVERY AND DEVELOPMENT AND WE MAY FAIL TO DEVELOP ANY PRODUCTS. Our stem cell technology is at the early pre-clinical stage for the brain stem cell and at the discovery phase for the liver and pancreas stem cells and has not yet led to the development of any proposed product. We may fail to discover the stem cells we are seeking, to develop any products, to obtain regulatory approvals, to enter clinical trials, or to commercialize any products. Any product using stem cell technology may fail to (i) survive and persist in the desired location, (ii) provide the intended therapeutic benefits, (iii) properly integrate into existing tissue in the desired manner, or (iv) achieve benefits therapeutically equal to or better than the standard of treatment at the time of testing. In addition, any such product may cause undesirable side effects. Results of early pre-clinical research may not be indicative of the results that will be obtained in later stages of preclinical or clinical research. If the appropriate regulatory authorities do not approve our products, or if we fail to maintain regulatory compliance, we would have limited ability to commercialize our products, and our business and results of operations would be harmed. Furthermore, since stem cells are a new form of therapy, the marketplace may not accept any products we may develop. If we do succeed in developing products, we will face many potential obstacles such as the need to obtain regulatory approvals, and to develop or obtain manufacturing, marketing and distribution capabilities. In addition, we will face substantial additional risks such as product liability. WE HAVE LIMITED LIQUIDITY AND CAPITAL RESOURCES AND MAY NOT OBTAIN THE SIGNIFICANT CAPITAL RESOURCES WE WILL NEED TO SUSTAIN OUR RESEARCH AND DEVELOPMENT EFFORTS. We have limited liquidity and capital resources and must obtain substantial additional capital to support our research and development programs, for acquisition of technology and intellectual property rights, and, to the extent we decide to undertake these activities ourselves, for pre-clinical and clinical testing of our anticipated products, pursuit of regulatory approvals, establishment of production capabilities, establishment of marketing and sales capabilities and distribution channels, and general administrative expenses. We owned 126,193 shares of Modex Therapeutics Ltd., stock with an estimated fair market value on June 30, 2000 of $19,220,165offering, based on the assumed public offering price of  $ 3.41 per share (the last reported sale price of approximately $152.00, which we convertedour 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 a marketthe exercise of any pre-funded warrants issued pursuant to this offering.

A $ 0.25 increase (decrease) in the assumed public offering price of  247.50 Swiss francs$ 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 June 30, 2000,the cover page of this prospectus, remains the same and we had been restrictedafter deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from selling thesethe exercise of the pre-funded warrants issued pursuant to this offering.

Similarly, a one million share increase (decrease) in the number of shares until December 23, 2000. On January 2, 2001,offered by us, as set forth on the marketcover page of this prospectus, would increase (decrease) the net proceeds to us by approximately $ 3.1 million, assuming the assumed public offering price of  Modex stock was 210.00 Swiss francs, which converts$ 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 $130.39 usingthis offering.

We currently intend to use the exchange rates on that date,net proceeds from this offering for attaining regulatory approvals for and represents an estimated fair market valuecommercializing our SCS device in the treatment of $16,453,825 for our holdings on that date. The performance of Modex stock since Modex's initial public offering does not predict its future valuehydrocephalus and NPH; expanding and developing the valueapplications of our holdings is subjectexisting 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 changepre-clinical studies; and could decrease significantly. On January 9, 2001, we sold 22,616 Modex sharesfor 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 price of 182.00 Swiss francs per share, which converts to $112.76 per share, for total proceeds of $2,550,230.27. In connectionfrom this offering, including with this sale, we agreed not to resell any more of our remaining 103,577 Modex shares until April 12, 2001. If we decide to sell more of our Modex shares, duerespect to the relatively small trading volume in Modex shares and the relatively large size of our holding, or other factors, we may not be able to sell our Modex shares at their market value or at all, and we may have to sell these shares at a significant discount to the market price. If we 4 sell some but not all of our Modex shares, it is likely that we would have to agree, in connection with the sale, to refrain from selling additional shares for several months. In addition, fluctuations in currency exchange rates could decrease the proceeds we might realize on a potential sale of Modex shares. We intend to pursue our needed capital resources through equity and debt financings, corporate alliances, grants and collaborative research arrangements. Our ability to complete any such arrangements successfully will depend upon market conditions and, more specifically, on continued progress in our research and development efforts.Matter. We may failalso use a portion of the net proceeds from this offering to obtain the necessary capital resources from any such sources when neededin-license, acquire, or on terms acceptable to us. If we do not obtain the necessary capital resources, we may have to delay, reduceinvest in complementary businesses, technologies, products or eliminate some or all of our research and development programs or license our technology or any potential products to third parties rather than commercializing them ourselves. WE HAVE PAYMENT OBLIGATIONS RESULTING FROM REAL PROPERTY OWNED OR LEASED BY US IN RHODE ISLAND, WHICH ADVERSELY AFFECT OUR ABILITY TO FUND OUR STEM CELL RESEARCH AND DEVELOPMENT. Prior to our reorganization in 1999 and the resulting consolidation of all functions in California, we carried out our former encapsulated cell therapy programs at facilities in Lincoln, Rhode Island, where we also had our administrative offices. Althoughassets. However, we have vacated these facilities, we have continuingno current commitments or obligations for lease payments and operating costs of approximately $950,000 per year for our former science and administrative facility, which we have leased through June 30, 2013, and debt service payments and operating costs of approximately $1,000,000 per year for our former encapsulated cell therapy pilot manufacturing facility. We are currently seeking to sublease the science and administrative facility and to sell the pilot manufacturing facility, but may not be able to do so. These continuing costs significantly reduce

We currently anticipate that our cashexisting resources, and adversely affect our ability to fund further development of our stem cell technology. The lease fortogether with the science and administrative facility contains a provision requiring occupancy of the premises and we currently may be in violation ofexpected net proceeds from this provision. If the landlord decides to pursue its rights, we may be required to pay the landlord the entire amount due for the rest of the lease period. WE MAY NEED BUT FAIL TO OBTAIN PARTNERS TO SUPPORT OUR STEM CELL DEVELOPMENT EFFORTS AND TO COMMERCIALIZE OUR TECHNOLOGY. Equity and debt financings alone may notoffering, will be sufficient to fund the costour planned operations until December 2021.

Our expected use of developingnet proceeds from this offering represents our stem cell technologiescurrent intentions based upon our present plans and we may need to rely on our ability to reach partnering arrangements to provide financial support for our stem cell discovery and development efforts. In addition, in order to successfully develop and commercialize our technology, we may need to enter into a wide variety of arrangements with corporate sponsors, pharmaceutical companies, universities, research groups and others. While we have engaged, and expect to continue to engage, in discussions regarding such arrangements, we have not reached any agreement regarding any such arrangement and we may fail to obtain any such agreement on terms acceptable to us, if at all. Even if we enter into these arrangements, we may not be able to satisfy our obligations under them or renew or replace them after their original terms. Furthermore, these arrangements may require us to grant certain rights to third parties, including exclusive marketing rights to one or more products, or may have other terms that are burdensome to us, and may involve the acquisition of our securities. If any of our collaborators terminates its relationship with us or fails to perform its obligations in a timely manner, the development or commercialization of our technology and potential products may be adversely affected. We entered into a Sponsored Research Agreement with the Scripps Research Institute under which we funded certain research in return for licenses or options to license the inventions resulting from the research. This agreement expired on November 14, 2000 and we are negotiating with Scripps to extend the term of this agreement or to enter into a new agreement.business condition. As of the date of this prospectus, we have not yet completed our negotiations with Scrippscannot currently allocate specific percentages of the net proceeds that we may use for the purposes specified above, and we cannot give any assurance 5 that our negotiations willpredict with certainty all of the particular uses for the net proceeds to be successful. If we are unable to extendreceived upon the termcompletion of this agreementoffering, or enter into a new agreement, we will have to find a replacement to perform this research or we will have to perform this research ourselves. In either case, we may experience delay and additional expense in connection with this research effort. WE HAVE A HISTORY OF OPERATING LOSSES AND WE MAY FAIL TO OBTAIN REVENUES OR BECOME PROFITABLE. We have incurred $124,237,900 in operating losses through September 30, 2000 and expect to continue to incur substantial operating losses in the future in order to conduct our research and development activities, and if those activities are successful, to fund clinical trials and other expenses. These expenses include the cost of acquiring technology, product testing, acquiring regulatory approvals, establishing production, marketing, sales and distribution programs, and administrative expenses. We have not earned any revenues from sales of any product. All of our past revenues have been derived from, and any revenues we may obtain for the foreseeable future are expected to be derived from, cooperative agreements, research grants, investments and interest on invested capital. We have no cooperative agreements and we have received only two research grants for our stem cell technology, and we may not obtain any such agreements or additional grants in the future, or receive any revenues from them. WE DO NOT ANTICIPATE RECEIVING FUTURE REVENUES FROM THE SALE OF OUR ENCAPSULATED CELL TECHNOLOGY. In December 1999, we sold our encapsulated cell therapy technology to Neurotech S.A. While under the terms of the sale we may receive royalty and other payments from Neurotech under certain circumstances, we do not anticipate receiving any material payments from Neurotech in the near future, if at all. WE DEPEND ON PATENTS AND PROPRIETARY RIGHTS TO PROTECT OUR INTELLECTUAL PROPERTY FROM INFRINGEMENT. NEVERTHELESS, SUCH PROTECTION IS UNCERTAIN AND, IF GAINED, MAY OFFER ONLY LIMITED PROTECTION. IF WE ARE UNABLE TO PROTECT OUR PATENTS AND PROPRIETARY RIGHTS, OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATION WILL BE HARMED. We own or license a number of patents or pending patent applications covering human nerve stem cell cultures, central nervous system stem cell cultures, neuroblast cultures, peripheral nervous system stem cell cultures, and an animal model for liver failure. Patent protection for products such as those we propose to develop is highly uncertain and involves complex and continually evolving factual and legal questions. The governmental authorities that consider patent applications can deny or significantly reduce the patent coverage requested in an application before or after issuing the patent. Consequently, we do not know whether any of our pending applications will result in the issuance of patents, or if any existing or future patents will provide sufficient protection or significant commercial advantage or if others will circumvent these patents. Since patent applications are secret until patents are issued in the United States or until the applications are published in foreign countries, and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we were the first to make the inventions covered by each of our pending patent applications or that we were the first to file patent applications for such inventions. Our patents may not issue from our pending or future patent applications or, if issued, may not be of commercial benefit to us, or may not afford us adequate protection from competing products. In addition, third parties may challenge our patents or governmental authorities may declare them invalid. In the event that a third party has also filed a patent application relating to inventions claimed in our patent applications, we may have to participate in proceedings to determine priority of invention. This could result in substantial uncertainties and cost for us, even if the eventual outcome is favorable to us, and the outcome might not be favorable to us. Even if a patent issues, a court could decide that the patent was issued invalidly. 6 IF OTHERS ARE FIRST TO DISCOVER AND PATENT ANY STEM CELLS WE ARE SEEKING TO DISCOVER, WE COULD BE BLOCKED FROM FURTHER WORK ON THAT STEM CELL, AND OUR BUSINESS WOULD BE HARMED. Because the first person or entity to discover and obtain a valid patent to a particular stem or progenitor cell may effectively block all others, it will be important to our development efforts for us or our collaborators to be the first to discover any stem cell that we are seeking. Failure to be the first could prevent us from commercializing all of our research and development related to such stem cell and have a material adverse effect on the Company. WE MAY NEED TO OBTAIN LICENSES TO THIRD PARTY PATENTS, AND MAY NOT BE ABLE TO GET THEM. A number of pharmaceutical, biotechnology and other companies, universities and research institutions have filed patent applications or have received patents relating to cell therapy, stem cells and other technologies potentially relevant to or necessary for our expected products. We cannot predict which, if any, of the applications will issue as patents. We are also aware of a number of patent applications and patents claiming use of genetically modified cells to treat disease, disorder or injury. We are aware of three patents issued to two competitors claiming certain methods for enriching central nervous system stem cells through gene modification of in vitro cultured cells. These patents were issued or licensed to NeuralStem and Layton Bioscience. It is possible that NeuralStem or Layton Bioscience will be able to produce commercially available stem cell products before we can. These genetically modified cells may be effective in treating defective, diseased or damaged central nervous system tissue. If third party patents or patent applications contain claims infringed by our technology and these claims are valid, we may be unable to obtain licenses to these patents at a reasonable cost, if at all, and may also be unable to develop or obtain alternative technology. If we are unable to obtain such licenses at a reasonable cost, our business could be significantly harmed. We may have to to defend ourselves in court against allegations of infringement of third party patents. Patent litigation is very expensive and could consume substantial resources and create significant uncertainties. An adverse outcome in such a suit could subject us to significant liabilities to third parties, require disputed rights to be licensed from third parties, or require us to cease using such technology. Proprietary trade secrets and unpatented know-how are also important to our research and development activities. We cannot be certain that others will not independently develop the same or similar technologies on their own or gain access to our trade secrets or disclose such technology, oramounts that we will beactually 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 meaningfully protect our trade secrets and unpatented know-how and keep them secret.enter into future licensing or collaboration arrangements. We require our employees, consultants, and significant scientific collaborators and sponsored researchers to execute confidentiality agreements upon the commencement of an employmentmay find it necessary or consulting relationship with us. These agreements may, however, fail to provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer or disclosure of such information or inventions. We have obtained rights from universities and research institutions to technologies, processes and compounds that we believe may be important to the development of our products. Licensors may cancel our licenses or convert them to non-exclusive licenses if we failadvisable to use the relevant technology or otherwise breach these agreements. Lossnet proceeds for other purposes, and our management will have broad discretion in the application of such licenses could expose us to the risks of third party patents and/or technology. We can give no assurance that any of these licenses will provide effective protection against our competitors. WE COMPETE WITH COMPANIES THAT HAVE SIGNIFICANT ADVANTAGES OVER US. The market for therapeutic products that address degenerative diseases is largenet proceeds, and competition is intense. We expect competition to increase. We believe that our most significant competitorsinvestors will be 7 fully integrated pharmaceutical companies and more established biotechnology companies, such as Biogen, Inc. and Genzyme, an Elan Corporation. These companies already produce or are developing treatments for degenerative diseases that are not stem-cell based, and they have significantly greater capital resources and expertise in research and development, manufacturing, testing, obtaining regulatory approvals and marketing than we do. Manyrelying on our judgment regarding the application of these potential competitors have significant products approved or in development that could be competitive with our potential products, and also operate large, well-funded research and development programs. In addition, we expect to compete with smaller companies such as NeuralStem and Layton Bioscience and with universities and other research institutions who are developing treatments for degenerative diseases that are stem-cell based. Our competitors may succeed in developing technologies and products that are more effective than those being developed by us, or that would render our technology obsolete or non-competitive. The relative speed with which we and our competitors can develop products, complete the clinical testing and approval processes, and supply commercial quantities of a product to market will affect our ability to gather market acceptance and market share. With respect to clinical testing, competition may delay progress by limiting the number of clinical investigators and patients available to test our potential products. DEVELOPMENT OF OUR TECHNOLOGY WILL BE SUBJECT TO EXTENSIVE GOVERNMENT REGULATION. Our research and development efforts, as well as any future clinical trials, and the manufacturing and marketing of any products we may develop, will be subject to extensive regulation by governmental authorities in the United States and other countries. The process of obtaining U.S. Food and Drug Administration and other necessary regulatory approvals is lengthy, expensive and uncertain. We or our collaborators may fail to obtain the necessary approvals to commence or continue clinical testing or to manufacture or market our potential products in reasonable time frames, if at all. In addition, the United States Congress and other legislative bodies may enact regulatory reforms or restrictions on the development of new therapies that could adversely affect the regulatory environment in which we operate or the development of any products we may develop. We base our research and development onnet proceeds from this offering.

Pending the use of human stem and progenitor cells obtainedthe net proceeds from fetal tissue.this offering, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

PRICE RANGE OF OUR COMMON STOCK

Our common stock is listed on The federal and state governments and other jurisdictions impose restrictions on the use of fetal tissue. These restrictions change from time to time and may become more onerous. Additionally, we may not be able to identify or develop reliable sources for the cells necessary for our potential products--that is, sources that follow all state and federal guidelines for cell procurement. Further, we may not be able to obtain such cells in the quantity or quality sufficient to satisfy the commercial requirements of our potential products. As a result we may be unable to develop or produce our products in a profitable manner. We may apply for statusNasdaq Capital Market under the Orphan Drug Act for certain of our therapies, in order to gain a seven year period of marketing exclusivity for those therapies. The U.S. Congress insymbol “MBOT.” On November 16 , 2018, the past considered, and in the future again may consider, legislation that would restrict the extent and duration of the market exclusivity of an orphan drug. If enacted, such legislation could prevent us from obtaining some or all of the benefits of the existing statute even if we were to apply for and be granted orphan drug status with respect to a potential product. WE DEPEND ON A LIMITED NUMBER OF KEY PERSONNEL. We are highly dependent on the principal members of our management and scientific staff and certain of our outside consultants, including the members of our scientific advisory board, our chief executive officer, each of our vice presidents and the directors of our neural stem cell and liver stem cell programs. Although we have entered into employment agreements with some of these individuals, they may terminate their agreements at any time. We currently have outside consultants and interim 8 personnel in key management and scientific positions who are not permanent employees. Loss of services of any of these individuals could have a material adverse effect on our operations, because these individuals possess management experience or specialized scientific skills which we do not otherwise have and which we may not be able to replace. In addition, our operations are dependent upon our ability to attract and retain additional qualified scientific and management personnel. More generally, we may not be able to attract and retain the personnel we need on acceptable terms given the competition for experienced personnel among pharmaceutical, biotechnology and health care companies, universities and research institutions. If we lose the services of these key personnel or are unable to attract and retain additional qualified personnel, we may have to delay, reduce or eliminate some or all of our research and development programs. HEALTHCARE INSURERS AND OTHER ORGANIZATIONS MAY NOT PAY FOR OUR PRODUCTS OR MAY IMPOSE LIMITS ON REIMBURSEMENTS. In both domestic and foreign markets, sales of potential products are likely to depend in part upon the availability and amounts of reimbursement from third party health care payor organizations, including government agencies, private health care insurers and other health care payors such as health maintenance organizations and self-insured employee plans. There is considerable pressure to reduce the cost of therapeutic products, and government and other third party payors are increasingly attempting to contain health care costs by limiting both coverage and the level of reimbursement for new therapeutic products, and by refusing, in some cases, to provide any coverage for uses of approved products for disease indications for which the Food and Drug Administration has not granted marketing approval. Significant uncertainty exists as to the reimbursement status of newly approved health care products. We can give no assurance that reimbursement will be provided by such payors at all or without substantial delay, or, if such reimbursement is provided, that the approved reimbursement amounts will be sufficient to enable us to sell products we develop on a profitable basis. Changes in reimbursement policy could also adversely affect the willingness of pharmaceutical companies to collaborate with us on the development of our stem cell technology. In certain foreign markets, pricing or profitability of prescription pharmaceuticals is subject to government control. We expect that there will continue to be a number of Federal and state proposals to implement government control over health care costs. Efforts at healthcare reform are likely to continue in future legislative sessions. We do not know what legislative proposals Federal or state governments will adopt or what actions Federal, state or private payers for healthcare goods and services may take in response to healthcare reform proposals or legislation. We cannot predict the effect government control and other healthcare reforms may have on our business. OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE. Our operating results have varied, and may in the future continue to vary, significantly from quarter to quarter due to a variety of factors. These factors include the receipt of one-time license or milestone payments under collaborative agreements, costs associated with the winddown of our encapsulated cell therapy programs, variation in the level of expenses related to our research and development efforts, receipt of grants or other support for our research and development efforts, and other factors. Quarterly comparisons of our financial results are not necessarily meaningful and you should not rely upon them as an indication of future performance. OUR STOCK PRICE MAY BE VOLATILE AND THIS VOLATILITY COULD RESULT IN LAWSUITS OR MAKE IT DIFFICULT TO RAISE CAPITAL. The marketclosing price for our common stock has been volatileas reported on The Nasdaq Capital Market was $ 3.41 per share. The following table sets forth the ranges of high and could decline below the offering price for the shares. We believe that the market price for our common stock could fluctuate substantially due to some or all of the risk factors enumerated above. 9 The stock market has recently experienced extreme price and volume fluctuations. These fluctuations have especially affected the market price of the stock of many high technology and health care-related companies. Such fluctuations have often been unrelated to the operating performance of these companies. Nonetheless, these broad market fluctuations may negatively affect the market price of our common stock. In the past, companies that have experienced volatility in the market price of their stock have been the objects of securities class action litigation. If we were the object of securities class action litigation, we could incur material costs and suffer a diversion of our management's attention and resources. In addition, volatility in our stock price may make it difficult for us to obtain additional capital resources through financings on terms acceptable to us.

14 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion of our financial condition and results of operations for the nine months ended September 30, 2000 and 1999 and the years ended December 31, 1999, 1998, and 1997 should be read in conjunction with our consolidated financial statements and notes to those statements and other financial information included elsewhere in this prospectus. RESULTS OF OPERATIONS OVERVIEW Since our inception in 1988, we have been primarily engaged in research and development of human therapeutic products. As a result of a restructuring in the second half of 1999, our sole focus is now on our stem cell technology. At the beginning of last year, by contrast, our corporate headquarters, most of our employees, and the main focus of our operations were primarily devoted to a different technology--encapsulated cell therapy, or ECT. Since that time, we terminated a clinical trial of the ECT then in progress, we wound down our other operations relating to the ECT, we terminated the employment of those who worked on the ECT, we sold the ECT and we relocated from Rhode Island to Sunnyvale, California. Comparisons with last year's results are correspondingly less meaningful than they may be under other circumstances. We were known as CytoTherapeutics, Inc., until May 23, 2000, when we changed our name to StemCells, Inc. We have not derived any revenues from the sale of any products, and we do not expect to receive revenues from product sales for at least several years. We have not commercialized any product and in order to do so we must, among other things, substantially increase our research and development expenditures as research and product development efforts accelerate and clinical trials are initiated. We have incurred annual operating losses since inception and expect to incur substantial operating losses in the future. As a result, we are dependent upon external financing from equity and debt offerings and revenues from collaborative research arrangements with corporate sponsors to finance our operations. There are no such collaborative research arrangements at this time and there can be no assurance that such financing or partnering revenues will be available when needed or on terms acceptable to us. Our results of operations have varied significantly from year to year and quarter to quarter and may vary significantly in the future due to the occurrence of material, nonrecurring events, including without limitation the receipt of one-time, nonrecurring licensing payments, and the initiation or termination of research collaborations, in addition to the winding-down of terminated research and development programs referred to above. NINE MONTHS ENDED SEPTEMBER 30, 2000 AND 1999 For the nine months ended September 30, 2000 and 1999, revenues from collaborative agreements totaled $0 and $5,021,707, respectively. The decrease in revenues resulted from the June 1999 termination of a Development, Marketing and License Agreement related to our former ECT. We have not entered into revenue-producing collaborations with respect to our platform of stem cell technologies. During the second quarter 2000 we realized a $1,427,686 gain in connection with our investment in Modex Therapeutics Ltd ("Modex"), a Swiss biotechnology company that completed an initial public offering on June 23, 2000. At September 30, 2000, we owned 126,193 shares with an estimated fair value of $27,204,333, based on the per share price of $215.58 which we converted from a market price of 372.00 Swiss francs on that date. On January 2, 2001 the market price was 210.00 Swiss Francs, which converts to $130.39 and results in an estimated fair value of $16,453,825 for the Company's 15 holdings on that date. On January 9, 2001, we sold 22,616 Modex shares for a net price of 182.00 Swiss francs per share, which converts to $112.76 per share, for total proceeds of $2,550,230.27. In connection with this sale, we agreed not to resell any more of our remaining 103,577 Modex shares until April 12, 2001. Research and development expenses totaled $3,350,101 for the nine months ended September 30, 2000, compared with $8,432,262 for the same period in 1999. The decrease of $5,082,161, or 60% from 1999 to 2000 is primarily attributable to the wind-down of research activities relating to the ECT. General and administrative expenses were $2,172,137 for the nine months ended September 30, 2000, compared with $3,195,672 for the same period in 1999. The decrease of $1,023,535, or 32%, from 1999 to 2000 was primarily attributable to lower payroll costs (approximately $882,000) resulting from the restructuring of administrative operations and to the establishment of a smaller corporate office in California (approximately $136,000). Wind-down expenses related to our ECT research, our Rhode Island operations and the transfer of our headquarters to Sunnyvale, California for the nine months ended September 30, 2000 and 1999 was $768,733 and $4,078,034 respectively. In 1999 we had created a reserve of $1,634,522 for wind-down expenses related to the first half of 2000, of which approximately $463,000 related to the carrying costs through an expected June 30, 2000 disposition of the Rhode Island facilities. During the first six months of 2000 we incurred $288,646 of costs in excess of the amounts reserved as of December 31, 1999 for the carrying costs, including lease payments, property taxes and utilities, of the Rhode Island facilities. During the third quarter we incurred an additional $480,087 in carrying costs for the Rhode Island facilities, as we were unable to dispose of them by June 30, 2000, as expected. These amounts were previously included in general and administrative expense, and have been reclassified to be separately disclosed as encapsulated cell therapy wind down and corporate relocation expense because they were directly related to the wind down and relocation. We anticipate that we will incur a similar amount in the fourth quarter of 2000 and in every quarter thereafter until we dispose of these facilities. We do not currently have a projected date for such disposal and there can be no assurance that we will be able to dispose of these facilities in a reasonable time, if at all. Some additional items that were more properly included in research and development were also reclassified out of general and administrative expense, and facilities costs were more accurately spread between research and development and general and administrative expense. Interest income for the nine months ended September 30, 2000 and 1999 was $218,480 and $504,114 respectively. The decrease in interest income in 2000 was attributable to the lower average investment balances during such period. Interest expense was $209,287 for the nine months ended September 30, 2000, compared with $236,836 for the same period in 1999. The decrease in 2000 was attributable to lower outstanding debt and capital lease balances in 2000 compared to 1999. Net loss for the nine months ended September 30, 2000 was $4,865,190 or ($0.25) per share, as compared to net loss of $10,483,760 or ($0.56) per share, for the comparable period in 1999. The decrease in net loss of $5,618,570 or 54% from the same period in 1999 was primarily attributable to the wind-down of research activities relating to the ECT and reflects a gain of $1,427,686 in connection with our investment in Modex. We (then known as CytoTherapeutics, Inc.) were one of the founders of Modex, a Swiss biotherapeutics company established in 1996 to pursue encapsulated cell technologies related to our former programs. After Modex' Initial Public offering on the Swiss Neue Market on June 23, 2000 and our sale of 23,807 shares, we owned 126,193 shares of Modex common stock. The IPO price was 168.00 Swiss Francs, and the share price on September 30, 2000 was 372.00 Swiss Francs. On January 2, 2001 the market price was 210.00 Swiss Francs. On January 9, 2001, we sold 22,616 Modex shares for a net price of 182.00 Swiss francs per share, which converts to $112.76 per share, for total proceeds of $2,550,230.27. In connection with this sale, we agreed not to resell any more of our remaining 103,577 Modex shares until April 12, 2001. 16 YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997 Revenues from collaborative agreements totaled $5,022,000, $8,803,000 and $10,617,000 for the years ending December 31, 1999, 1998 and 1997, respectively. We earned revenues primarily from a Development, Marketing and License Agreement with AstraZeneca Group plc, which we signed in March 1995. The decrease in revenues from 1998 to 1999 resulted primarily from the June 1999 termination of the AstraZeneca Agreement. 1997 revenues included a $3,000,000 milestone payment from AstraZeneca related to the Phase II clinical trials for an ECT product. Research and development expenses totaled $9,984,000 in 1999, as compared to $17,659,000 in 1998 and $18,604,000 in 1997. The decrease of $7,668,000, or 43%, from 1998 to 1999 was primarily attributable to the wind-down of research activities relating to the ECT, precipitated by termination of the AstraZeneca Agreement. The decrease of $945,000, or 5%, from 1997 to 1998 was primarily attributable to a reduction in spending on research agreements and a reduction in research and development personnel. Acquired research and development consists of a one-time charge of $8,344,000 related to the acquisition of StemCells California, Inc., in 1997. Commercialization of this technology will require significant incremental research and development expenses over a number of years. With the recent completion of the restructuring of our research operations, we are now focused solely on the research and development of our platform of stem cell technologies, which encompasses the technology acquired upon the acquisition of StemCells California, Inc. and related technology we have developed or licensed. General and administrative expenses were $4,927,303 for the year ended December 31, 1999, compared with $4,603,000 in 1998 and $6,158,000 in 1997. The 1999 general administrative expenses were positively impacted by the reduction in facility costs that were included in wind-down ($239,000), reduction in amortization of patents and intangible assets of approximately $338,000, as well as reduced activities and related personnel costs estimated at approximately $500,000 that were not incurred. This was due to the wind-down of our ECT programs and relocation of our headquarters in October 1999. The reduction of $1,555,000, or 25%, from 1997 to 1998 was primarily attributable to a reduction in legal fees, recruiting and relocation expenses, as well as a reduction in employees. Wind-down and relocation expenses totaled $6,047,806 for the year ended December 31, 1999; no such expenses were incurred in 1998 and 1997. These expenses relate to the wind-down of our encapsulated cell technology research and our other Rhode Island operations the transfer of our corporate headquarters to Sunnyvale, California. They include accruals of approximately $1,554,000 for employee severance costs, $1,858,000 in losses and reserves for the write-down of related patents and fixed assets, $1,172,000 for our costs of settlement of a 1989 funding agreement with the Rhode Island Partnership for Science and Technology, $702,000 of estimated additional carrying costs through an expected June 30, 2000 disposition of the Rhode Island facilities, and other related expenses totaling $762,000. Interest income for the years ended December 31, 1999, 1998 and 1997 totaled $564,000, $1,254,000 and $1,931,000, respectively. The average cash and investment balances were $10,663,000, $21,795,000 and $33,343,000 in 1999, 1998 and 1997, respectively. The decrease in interest income from 1997 to 1998 to 1999 was attributable to lower average balances. In 1999, interest expense was $335,000, compared with $472,000 in 1998 and $438,000 in 1997. The decrease from 1998 to 1999 was attributable to lower outstanding debt and capital lease balances. The increase from 1997 to 1998 was primarily attributable to capitalization of $210,000 of interest on the new facility in 1997. 17 In October 1997, we recognized a gain in the amount of $3,387,000 related to the sale of 50 percent of our interest in Modex Therapeutics Ltd. The net loss in 1999, 1998 and 1997 was $15,709,000, $12,628,000, and $18,114,000, respectively. The loss per share was $0.84, $0.69 and $1.08 in 1999, 1998 and 1997, respectively. The increase from 1998 to 1999 is primarily attributable to the elimination of revenue from the AstraZeneca Agreement, which was terminated in June 1999, as well as expenses related to the wind-down of our ECT research and our other Rhode Island operations, the transfer of our corporate headquarters to Sunnyvale, California and an accrual of approximately $1,172,000 for our estimate of the costs of settlement of the funding agreement with RIPSAT. The decrease from 1997 to 1998 was attributable to a one-time charge of $8,344,000 for acquired research and development related to the purchase of StemCells California, Inc. offset by the $3,387,000 gain on a partial sale of our interest in Modex in 1997. The 1999 decrease in patents of $3,229,932 from 1998 was primarily due to management's decision to wind down the ECT program and dispose of the related intellectual property. During the fourth quarter of 1999 we sold the patents related to our encapsulated cell technology to Neurotech for $3,000,000. Accrued expenses increased by $1,584,949, primarily due to the accrual of approximately $1,172,000 for our estimate of the costs of settlement of a 1989 funding agreement with the Rhode Island Partnership for Science and Technology and $463,000 for the estimated lease payments and operating costs of the Rhode Island facilities through an expected disposal date of June 30, 2000. LIQUIDITY AND CAPITAL RESOURCES Since our inception, we have financed our operations through the sale of common and preferred stock, the issuance of long-term debt and capitalized lease obligations, revenues from collaborative agreements, research grants and interest income. We had unrestricted cash and cash equivalents totaling $5,535,264 at June 30, 2000. Cash equivalents are invested in money market funds. We also hold 126,193 shares of Modex stock as of January 2, 2001, which is publicly traded on the Swiss Neue Market exchange. While our Modex stock had an estimated fair market value of $27,204,333 on September 30, 2000 (and $16,453,825 on January 2, 2001), the fair market value of our Modex stock has varied significantly since the Modex public offering and may continue to vary significantly based on increases and decreases in the reported per share price, in Swiss francs, of the Modex stock and on foreign currency exchange rates. We had been prohibited under a lock-up agreement entered into at the time of Modex's public offering from selling any of our Modex shares until December 23, 2000. On January 9, 2001, we sold 22,616 Modex shares for a net price of 182.00 Swiss francs per share, which converts to $112.76 per share, for total proceeds of $2,550,230.27. In connection with this sale, we agreed not to resell any more of our remaining 103,577 Modex shares until April 12, 2001. There is a limited trading market for Modex stock, and if we were to attempt to sell any significant portion of our remaining Modex holdings, we would likely be able to do so only at a significant discount to the then market price, if at all. If we sell some but not all of our Modex shares, it is likely that we would have to agree, in connection with the sale, to refrain from selling additional shares for several months. Our liquidity and capital resources were, in the past, significantly affected by our relationships with corporate partners, which were related to our former ECT. These relationships are now terminated, and we have not yet established corporate partnerships with respect to our stem cell technology. In March 1995, we signed a collaborative research and development agreement with AstraZeneca plc for the development and marketing of certain encapsulated-cell products to treat pain. AstraZeneca made an initial, nonrefundable payment of $5,000,000, included in revenue from collaborative 18 agreements in 1995, a milestone payment of $3,000,000 in 1997 and was to remit up to an additional $13,000,000 subject to achievement of certain development milestones. Under the agreement, we were obligated to conduct certain research and development pursuant to a four-year research plan agreed upon by the parties. Over the term of the research plan, we originally expected to receive annual payments of $5 million to $7 million from AstraZeneca, which was to approximate the research and development costs incurred by us under the plan. Subject to the successful development of such products and obtaining necessary regulatory approvals, AstraZeneca was obligated to conduct all clinical trials of products arising from the collaboration and to seek approval for their sale and use. AstraZeneca had the exclusive worldwide right to market products covered by the agreement. Until the later of either the expiration of all patents included in the licensed technology or a specified fixed term, we were entitled to a royalty on the worldwide net sales of such products in return for the marketing license granted to AstraZeneca and our obligation to manufacture and supply products. AstraZeneca had the right to terminate the original agreement beginning April 1, 1998. On June 24, 1999, AstraZeneca informed us of the results of AstraZeneca's analysis of the double-blind, placebo-controlled trial of a potential ECT product, an encapsulated bovine cell implant for the treatment of severe, chronic pain in cancer patients. AstraZeneca determined that, based on criteria it established, the results from the 85-patient trial did not meet the minimum statistical significance for efficacy established as a basis for continuing worldwide trials for the therapy. AstraZeneca therefore indicated that it did not intend to further develop the bovine cell-containing implant therapy and exercised its right to terminate the agreement. See also Note 17--"Research Agreements" to the Accompanying Consolidated Financial Statements. In the third quarter of 1999, we announced restructuring plans for the wind-down of operations relating to our ECT and to focus our resources on the research and development of our platform of proprietary stem cell technologies. We terminated approximately 68 full time employees and, in October 1999, relocated our corporate headquarters to Sunnyvale, California. We recorded $6,047,806 of wind-down expenses including employee separation and relocation costs during 1999. On December 30, 1999 we sold our ECT and assigned our intellectual property assets in it to Neurotech S.A. for a payment of $3,000,000, royalties on future product sales, and a portion of certain Neurotech revenues from third parties. In addition, we retained certain non-exclusive rights to use ECT in combination with our proprietary stem cell technologies and in the field of vaccines for prevention and treatment of infectious diseases. We received $2,800,000 of the initial payment on January 3, 2000 with a remaining balance of $200,000 placed in escrow, to be released to us upon demonstration satisfactory to Neurotech that certain intellectual property is not subject to other claims. As part of our restructuring of operations and relocation of corporate headquarters to Sunnyvale, California, we identified a significant amount of excess fixed assets. In December of 1999, we completed the disposition of those excess fixed assets, from which we received more than $746,000. The proceeds are being used to fund our continuing operations. In July 1999, as a result of our decision to close our Rhode Island facilities, the Rhode Island Partnership for Science and Technology, or RIPSAT, alleged that we were in default under a June, 1989 Funding Agreement, and demanded payment of approximately $2.6 million. While we believe we were not in default under the Funding Agreement, we deemed it best to resolve the dispute without litigation and, on March 3, 2000, entered into a settlement agreement with RIPSAT, the Rhode Island Industrial Recreational Building Authority, or IRBA, and the Rhode Island Industrial Facilities Corporation, or RIIFC. We agreed to pay RIPSAT $1,172,000 in full satisfaction of all of our obligations to them under the Funding Agreement. At the same time, IRBA agreed to return to us the full amount of our debt service reserve, comprising approximately $610,000 of principal and interest, relating to the bonds we had with IRBA and RIIFC. The $610,000 debt service reserve was transferred directly to RIPSAT, leaving the remainder of approximately $562,000 to be paid by us. We made this payment in March of 2000. 19 Our liquidity and capital resources could have also been affected by a claim by Genentech, Inc., arising out of the their collaborative development and licensing agreement with us relating to the development of products for the treatment of Parkinson's disease; however, the claim was resolved with no effect on our resources. On May 21, 1998, Genentech exercised its right to terminate the Parkinson's collaboration and demanded that we redeem, for approximately $3,100,000, certain shares of our redeemable Common Stock held by Genentech. Genentech's claim was based on provisions in the agreement requiring us to redeem, at the price of $10.01 per share, the shares representing the difference between the funds invested by Genentech to acquire such stock and the amount expended by us on the terminated program less an additional $1,000,000. In March 2000, we entered into a Settlement Agreement with Genentech under which Genentech released us from any obligation to redeem any shares of our Common Stock held by Genentech, without cost to us. Accordingly, the $5.2 million of redeemable common stock shown as a liability in our December 31, 1999 balance sheet was transferred to equity in March, 2000 without any impact on our liquidity and capital resources. We and Genentech also agreed that all collaborations between us were terminated, and that neither of us had any rights to the intellectual property of the other. In May 1996, we secured an equipment loan facility with a bank in the amount of $2,000,000. On August 5, 1999 we made a payment of approximately $752,000 of principal and interest to the lender to retire this loan facility rather than seek a waiver by the lender of our violation of a loan covenant requiring us to maintain unrestricted liquidity in an amount equal to or in excess of $10 million. We continue to have outstanding obligations in regard to our former facilities in Lincoln, Rhode Island, including lease payments and operating costs of approximately $950,000 per year associated with our former research laboratory and corporate headquarters building, and debt service payments and operating costs of approximately $1,000,000 per year with respect to our pilot manufacturing and cell processing facility. We are actively seeking to sublease, assign or sell our interests in these facilities. Failure to do so within a reasonable period of time will have a material adverse effect on our liquidity and capital resources. On April 13, 2000, we sold 1,500 shares of our 6% cumulative convertible preferred stock plus warrants for a total of 75,000 shares of our common stock to two members of our Board of Directors for $1,500,000, on terms more favorable to us than we were able to obtain from outside investors. The face value of the shares of preferred stock is convertible at the option of the holders into common stock at $3.77 per share. The holders of the preferred stock have liquidation rights equal to their original investments plus accrued but unpaid dividends. The investors would be entitled to make additional investments in our securities on the same terms as those on which we complete offerings of our securities with third parties within 6 months, if any such offerings are completed. They have waived that right with respect to the common stock transactions described below. If offerings totaling at least $6 million are not completed during the 6 months, the investors have the right to acquire up to a total of 1,126 additional shares of convertible preferred stock, the face value of which is convertible at the option of the holders into common stock at $6.33 per share. Any unconverted preferred stock is converted, at the applicable conversion price, on April 13, 2002 in the case of the original stock and two years after the first acquisition of any of the additional 1,126 shares, if any are acquired. The warrants expire on April 13, 2005. On August 3, 2000, we completed a $4 million common stock financing transaction with Millennium Partners, LP, or the Fund, an investment fund with more than a billion dollars in assets under management. We received $3 million of the purchase price at the closing and received the remaining $1 million upon effectiveness of a registration statement covering the shares purchased by the Fund. The Fund purchased our common stock at $4.33 per share. The Fund may be entitled, pursuant to an adjustable warrant issued in connection with the sale of common stock to the Fund, to receive additional shares of common stock on eight dates beginning six months from the closing and every three months thereafter. The number of additional shares the Fund may be entitled to on each 20 date will be based on the number of shares of common stock outstanding as of September 30, 2018.

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 underlying share. In addition, the Fund has the option for twelve months to purchase up to $3 millionshare of additional common stock.

At the closing on August 30, 2000, we issued to the Fund an adjustable warrant similar to the one issued on August 3, 2000. This adjustable warrant was canceled by agreement between us and the Fund on November 1, 2000. The Fund also received a warrant to purchase up to 19,900 shares of common stock that we offer in this offering, our actual expenses, and other terms of this offering determined at $6.03pricing.

To the extent that options, warrants or other convertible securities outstanding as of September 30, 2018 have limited liquidity and capital resources and must obtain significantbeen 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 resources in the future in order to sustain our product development efforts. Substantial additional funds will be required to support our research and development programs, for acquisition of technologies and intellectual property rights, for preclinical and clinical testing of our anticipated products, pursuit of regulatory approvals, acquisition of capital equipment, laboratory and office facilities, establishment of production capabilities and for general and administrative expenses. Our ability to obtain additional capital will be substantially dependent on our ability to obtain partnering support for our stem cell technology and, in the near term, on our ability to realize proceeds from the sale, assignment or sublease of our facilities in Rhode Island. Failure to do so will have a material effect on our liquidity and capital resources. Until our operations generate significant revenues from product sales, we must rely on cash reserves and proceeds from equity and debt offerings, proceeds from the transfer or sale of our intellectual property rights, equipment, facilities or investments, government grants and funding from collaborative arrangements, if obtainable, to fund our operations. We intend to pursue opportunities to obtain additional financing in the future through equity and debt financings, grants and collaborative research arrangements. The source, timing and availability of any future financing will depend principally upon market conditions, interest rates and, more specifically, on our progress in our exploratory, preclinical and future clinical development programs. Lack of necessary funds may require us to delay, reduce or eliminate some or all of our research and product development programs or to license our potential products or technologies to third parties. Funding may not be available when needed--at all, or on terms acceptable to us. While our cash requirements may vary, as noted above, we currently expect that our existing capital resources, including income earned on invested capital, will be sufficient to fund our operations into the first quarter of 2001. Our cash requirements may vary, however, depending on numerous factors. Lack of necessary funds may require us to delay, scale back or eliminate some or all of our research and product development programs and/or our capital expenditures or to license our potential products or technologies to third parties. 21 BUSINESS OVERVIEW We are engaged in research aimed at the development of therapies that would use stem and progenitor cells derived from fetal or adult sources to treat, and possibly cure, human diseases and injuries such as Parkinson's disease, hepatitis, diabetes, and spinal cord injuries. The body uses certain key cells known as stem cells to produce all the functional mature cell types found in normal organs of healthy individuals. Progenitor cells are cells that have already developed from the stem cells, but can still produce one or more types of mature cells within an organ. Many diseases, such as Alzheimer's, Parkinson's, and other degenerative diseases of the brain or nervous system, involve the failure of organs that cannot be transplanted. Other diseases, such as hepatitis and diabetes, involve organs such as the liver or pancreas that can be transplanted, but there is a very limited supply of those organs available for transplant. We estimate, based on information available to us from the Alzheimer's Association, the Centers for Disease Control, the Family Caregiver's Alliance and the Spinal Cord Injury Information Network, that these conditions affect more than 18 million people in the United States and account for more than $150 billion annually in health care costs. Our proposed therapies are based on the transplanting of healthy human stem and progenitor cells to repair or replace central nervous system, pancreas or liver tissue that has been damaged or lost as a result of disease or injury, potentially returning patients to productive lives and significantly reducing health care costs. We believe that we have achieved significant progress in research regarding stem cells of the central nervous system through the advances we have made in the isolation, purification and transplantation of central nervous system stem and progenitor cells. We have also made advances in our research programs to discover the stem cells of the pancreas and of the liver. We have established an intellectual property position in all three areas of our stem cell research--the central nervous system, the pancreas and the liver--by patenting our discoveries and entering into exclusive licensing arrangements. We believe that, if successfully developed, our platform of stem cell technologies may create the basis for therapies that would address a number of conditions with significant unmet medical needs. CELL THERAPY BACKGROUND ROLE OF CELLS IN HUMAN HEALTH AND TRADITIONAL THERAPIES Cells maintain normal physiological function in healthy individuals by secreting or metabolizing substances, such as sugars, amino acids, neurotransmitters and hormones, which are essential to life. When cells are damaged or destroyed, they no longer produce, metabolize or accurately regulate those substances. Impaired cellular function is associated with the progressive decline common to many degenerative diseases of the nervous system, such as Parkinson's disease, Alzheimer's disease and amyotrophic lateral sclerosis. Recent advances in medical science have identified cell loss or impaired cellular function as leading causes of degenerative diseases. Biotechnology advances have led to the identification of some of the specific substances or proteins that are deficient. While administering these substances or proteins as medication does overcome some of the limitations of traditional pharmaceuticals such as lack of specificity, there is no existing technology that can deliver them to the precise sites of action and in the appropriate physiological quantities or for the duration required to cure the degenerative condition. Cells, however, do this naturally. As a result, investigators have considered replacing failing cells that are no longer producing the needed substances or proteins by implanting stem or progenitor cells capable of regenerating the cell that the degenerative condition has damaged or destroyed. Where 22 there has been irreversible tissue damage or organ failure, transplantation of stem cells offers the possibility of generating new and healthy tissue, thus potentially restoring the organ function and the patient's health. THE POTENTIAL OF OUR STEM CELL-BASED THERAPY We believe that, if successfully developed, stem cell-based therapy--the use of stem or progenitor cells to treat diseases--has the potential to provide a broad therapeutic approach comparable in importance to traditional pharmaceuticals and genetically engineered biologics. Stem cells are rare and only available in limited supply, whether from the patients themselves or from donors. Cells obtained from the same person who will receive them may be abnormal if the patient is ill or the tissue is contaminated with disease-causing cells. Also, the cells can often be obtained only through significant surgical procedures. The challenge, therefore, has been three-fold: 1) to identify the stem cells; 2) to create techniques and processes that can be used to expand these rare cells in sufficient quantities for effective transplants; and 3) to establish a bank of normal human stem or progenitor cells that can be used for transplantation into individuals whose own cells are not suitable because of disease or other reasons. We have developed and demonstrated a process, based on a proprietary IN VITRO culture system in chemically defined media, that reproducibly grows normal human central nervous system, or CNS, stem and progenitor cells. We believe this is the first reproducible process for growing normal human CNS stem cells. More recently, we have discovered markers on the cell surface that identify the human CNS stem cells. This allows us to purify them and eliminate other unwanted cell types. Together, these discoveries enable us to select normal human CNS stem cells and to expand them in culture to produce a large number of pure stem cells. Because these cells have not been genetically modified, they may be especially suitable for transplantation and may provide a safer and more effective alternative to therapies that are based on cells derived from cancer cells, from cells modified by a cancer gene to make them grow, from an unpurified mixture of many different cell types, or from animal derived cells. We believe our proprietary stem cell technologies may enable therapies to replace specific cells that have been damaged or destroyed, permitting the restoration of function through the replacement of normal cells where this has not been possible in the past. In our research, we have shown that stem cells of the central nervous system transplanted into hosts are accepted, migrate, and successfully specialize to produce mature neurons and glial cells. More generally, because the stem cell is the pivotal cell that produces all the functional mature cell types in an organ, we believe these cells, if successfully identified and developed for transplantation, may serve as platforms for five major areas of regenerative medicine and biotechnology: - tissue repair and replacement, - correction of genetic disorders, - drug discovery and screening, - gene discovery and use, and - diagnostics. 23 We will be pursuing key alliances in these areas. OUR PLATFORM OF STEM CELL TECHNOLOGIES Stem cells have two defining characteristics: - some of the cells developed from stem cells produce all the kinds of mature cells making up the particular organ; and - they "self renew"--that is, other cells developed from stem cells are themselves new stem cells, thus permitting the process to continue again and again. Stem cells are known to exist for many systems of the human body, including the blood and immune system, the central and peripheral nervous systems (including the brain), and the liver, pancreas endocrine, and the skin systems. These cells are responsible for organ regeneration during normal cell replacement and, to a more or less limited extent, after injury. We believe that further research and development will allow stem cells to be cultivated and administered in ways that enhance their natural function, so as to form the basis of therapies that will replace specific subsets of cells that have been damaged or lost through disease, injury or genetic defect. We also believe that the person or entity that first identifies and isolates a stem cell and defines methods to culture any of the finite number of different types of human stem cells will be able to obtain patent protection for the methods and the composition, making the commercial development of stem cell treatment and possible cure of currently intractable diseases financially feasible. Our strategy is to be the first to identify, isolate and patent multiple types of human stem and progenitor cells with commercial importance. Our portfolio of issued patents includes a method of culturing normal human central nervous system stem and progenitor cells in our proprietary chemically defined medium, and our published studies show that these cultured and expanded cells give rise to all three major cell types of the central nervous system. Also, a separate study sponsored by us using these cultured stem and progenitor cells showed that the cells are accepted, migrate, and successfully specialize to produce neurons and glial cells. More recently, we announced the results of a new study that showed that human central nervous system stem cells can be successfully isolated by markers present on the surface of freshly obtained brain cells. We believe this is the first reproducible process for isolating highly purified populations of well-characterized normal human central nervous system stem cells, and have applied for a composition of matter patent. Because the cells are highly purified and have not been genetically modified, they may be especially suitable for transplantation and may provide a safer and more effective alternative than therapies that are based on cells derived from cancer cells, or from cells modified by a cancer gene to make them grow, or from an unpurified mixture of many different cell types or cells derived from animals. We have also filed an improved process patent for the growth and expansion of these purified normal human central nervous system cells. Neurological disorders such as Parkinson's disease, epilepsy, Alzheimer's disease, and the side effects of stroke, affect a significant portion of the U.S. population and there currently are no effective long-term therapies for them. We believe that therapies based on our process for identifying, isolating and culturing neural stem and progenitor cells may be useful in treating such diseases. We are continuing our research into, and have initiated the development of, human central nervous system stem and progenitor cell-based therapies for these diseases. We continue to advance our research programs to discover the islet stem cell in the human pancreas and the liver stem cell. Islet cells are the cells that produce insulin, so islet stem cells may be useful in the treatment of Type 1 diabetes and those cases of Type 2 diabetes where insulin secretion is 24 defective. Liver stem cells may be useful in the treatment of diseases such as hepatitis, cirrhosis of the liver and liver cancer. EXPECTED ADVANTAGES OF OUR STEM CELL TECHNOLOGY NO OTHER TREATMENT To the best of our knowledge, no one has developed an FDA-approved method for replacing lost or damaged tissues from the human nervous system. Replacement of tissues in other areas of the human body is limited to those few sites, such as bone marrow or peripheral blood cell transplants, where transplantation of the patient's own cells is now feasible. In a few additional areas, including the liver, transplantation of donor organs is now used, but is limited by the scarcity of organs available through donation. We believe that our stem cell technologies have the potential to reestablish function in at least some of the patients who have suffered the losses referred to above. REPLACED CELLS PROVIDE NORMAL FUNCTION Because stem cells can duplicate themselves, or self-renew, and specialize into the multiple kinds of cells that are commonly lost in various diseases, transplanted stem cells may be able to migrate limited distances to the proper location within the body, to expand and specialize and to replace damaged or defective cells, facilitating the return to proper function. We believe that such replacement of damaged or defective cells by functional cells is unlikely to be achieved with any other treatment. RESEARCH EFFORTS AND PRODUCT DEVELOPMENT PROGRAMS OVERVIEW OF RESEARCH AND PRODUCT DEVELOPMENT STRATEGY We have devoted substantial resources to our research programs to isolate and develop a series of stem and progenitor cells that we believe can serve as a basis for replacing diseased or injured cells. Our efforts to date have been directed at methods to identify, isolate and culture large varieties of stem and progenitor cells of the human nervous system, liver and pancreas and to develop therapies utilizing these stem and progenitor cells. The following table lists the potential therapeutic indications for, and current status of, our primary research and product development programs and projects. The table is qualified in its entirety by reference to the more detailed descriptions of such programs and projects appearing elsewhere in this prospectus. We continually evaluate our research and product development efforts and reallocate resources among existing programs or to new programs in light of experimental results, commercial potential, availability of third party funding, likelihood of near-term efficacy, collaboration success or significant technology enhancement, as well as other factors. Our research and product development 25 programs are at relatively early stages of development and will require substantial resources to commercialize.

"Preclinical" refers to further testing of a defined product candidate IN VITRO and in animals prior to clinical studies. RESEARCH AND DEVELOPMENT PROGRAMS Our portfolio of stem cell technology results from our exclusive licensing of central nervous system, stem and progenitor cell technology, animal models for the identification and/or testing of stem and progenitor cells and our own research and development efforts to date. We believe that therapies using stem cells represent a fundamentally new approach to the treatment of diseases caused by lost or damaged tissue. We have assembled an experienced team of scientists and scientific advisors to consult with and advise our scientists on their continuing research and development of stem and progenitor cells. This team includes, among others, Irving L. Weissman, M.D., of Stanford University, Fred H. Gage, Ph.D., of The Salk Institute and David Anderson, Ph.D., of the California Institute of Technology. BRAIN STEM AND PROGENITOR CELL RESEARCH AND DEVELOPMENT PROGRAM We began our work with central nervous system stem and progenitor cell cultures in collaboration with NeuroSpheres, Ltd., in 1992. We believe that NeuroSpheres was the first to invent these cultures. We are the exclusive, worldwide licensee from NeuroSpheres to such inventions and associated patents and patent applications for all uses, including transplantation in the human body, as embodied in these patents. See "License Agreements and Sponsored Research Agreements--NeuroSpheres, Ltd." 26 In 1997, our scientists invented a reproducible method for growing human CNS, stem and progenitor cells in cultures. In preclinical IN VITRO and early IN VIVO studies, we demonstrated that these cells specialize into all three of the cell types of the central nervous system. Because of these results, we believe that these cells may form the basis for replacement of cells lost in certain degenerative diseases. We are continuing research into, and have initiated the development of, our human CNS stem and progenitor cell cultures. We have initiated the cultures and demonstrated that these cultures can be expanded for a number of generations IN VITRO in chemically defined media. In collaboration with us, Dr. Anders Bjorklund has shown that cells from these cultures can be successfully transplanted and accepted into the brains of rodents where they subsequently migrated and specialized into the appropriate cell types for the site of the brain into which they were placed. In 1998, we expanded our preclinical efforts in this area by initiating programs aimed at the discovery and use of specific monoclonal antibodies to facilitate identification and isolation of CNS and other stem and progenitor cells or their specialized progeny. Also in 1998, our researchers devised methods to advance the IN VITRO culture and passage of human CNS stem cells that resulted in a 100-fold increase in CNS stem and progenitor cell production after 6 passages. We are expanding our preclinical efforts toward the goal of selecting the proper indications to pursue. In December 1998, we announced that the US Patent and Trademark Office had granted patent No. 5,851,832, covering our methods for the human CNS cell cultures containing central nervous system stem cells, for compositions of human CNS cells expanded by these methods, and for use of these cultures in human transplantation. These human CNS stem and progenitor cells expanded in culture may be useful for repairing or replacing damaged central nervous system tissue, including the brain and the spinal cord. In October 1999, the US Patent and Trademark Office granted patent number 5,968,829 entitled "Human CNS Neural Stem Cells," covering our composition of matter patent for human CNS stem cells, and also allowed a separate patent application for our media for culturing human CNS stem cells. Also in 1999, we announced the filing of a US patent application covering our proprietary process for the direct isolation of normal human CNS stem cells based on the markers found to be present on the surface of freshly obtained brain cells. Since the filing of this patent application, our researchers have completed a study designed to identify, isolate and culture human CNS stem cells utilizing this proprietary process. In November 1999, we announced the study's first results: Our researchers, by using our proprietary markers on the surface of the cell, had succeeded in identifying, isolating and purifying human CNS stem cells from brain tissue, and were able to expand the number of these cells in culture. We believe that this is the first study to show a reproducible process for isolating highly purified populations of well-characterized normal human CNS stem cells. Because the cells are normal human CNS stem cells and have not been genetically modified, they may be especially suitable for transplantation and may provide a safer and more effective alternative to therapies that are based on cells derived from cancer cells or from an unpurified mix of many different cell types, or from animal derived cells. In January 2000, we reported what we regard as an even more important result: In long term animal studies, our researchers were able to take these purified and expanded stem cells and transplant them into normal mouse brain hosts, where they take hold and grow into neurons and glial cells. During the course of the study, the transplanted human CNS stem cells survived for as long as one year and migrated to specific functional domains of the host brain, with no sign of tumor formation or adverse effects on the animal recipients; moreover, the cells were still dividing. These findings show that when CNS stem cells isolated and cultured with our proprietary processes are transplanted, they adopt the characteristics of the host brain and act like normal stem cells. In other words, the study suggests the possibility of a continual replenishment of normal human brain cells. 27 As noted above, human CNS stem and progenitor cells harvested and purified and expanded using our proprietary processes may be useful for creating therapies for the treatment of degenerative brain diseases such as Parkinson's, Huntington's and Alzheimer's disease. These conditions affect more than 5 million people in the United States and there are no effective long-term therapies currently available. We believe the ability to purify human brain stem cells directly from fresh tissue is important because: - it provides an enriched source of normal stem cells, not contaminated by other unwanted or diseased cell types, that can be expanded in culture without fear of also expanding some unwanted cell types; - it opens the way to a better understanding of the properties of these cells and how they might be manipulated to treat specific diseases. For example, in certain genetic diseases such as Tay Sachs and Gaucher's, a key metabolic enzyme required for normal development and function of the brain is absent. Brain-derived stem cell cultures might be genetically modified to produce those proteins. The modified brain stem cells could be transplanted into patients with these genetic diseases; - the efficient acceptance of these non-transformed normal human stem cells into host brains means that the cell product can be tested in animal models for its ability to correct deficiencies caused by various human neurological diseases. This technology could also provide a unique animal model for the testing of drugs that act on human brain cells either for effectiveness of the drug against the disease or its toxicity to human nerve cells. PANCREAS STEM CELLS DISCOVERY RESEARCH PROGRAMS Our discovery program directed to the identification, isolation and culturing of the pancreas stem and progenitor cells is currently being conducted by Nora Sarvetnick, Ph.D., of The Scripps Research Institute, in collaboration with some of our senior researchers. According to diabetes and juvenile diabetes foundations, between 800,000 and 1.5 million Americans have Type 1 diabetes, which is often called "juvenile diabetes" and most commonly diagnosed in childhood; and 30,000 new patients are diagnosed with the disease every year. It is a costly, serious, lifelong condition, requiring constant attention and insulin injections every day for survival. About 15 million other people in the United States have Type 2 diabetes mellitus, which is also a chronic and potentially fatal condition; and more than 700,000 new patients are diagnosed annually. In 1998, we obtained an exclusive, worldwide license from The Scripps Research Institute to novel technology developed by Dr. Sarvetnick which may facilitate the identification and isolation of pancreas stem and progenitor cells by using a mouse model that continuously regenerates the pancreas. We believe that stem cells produce the regeneration, in which case this animal model may be useful for identifying specific markers on the cell surface unique to the pancreas stem cells. We believe this may lead to the development of cell-based treatments for Type 1 diabetes and that portion of Type 2 diabetes characterized by defective secretion of insulin. In 1999, advances in the research sponsored by us resulted in our obtaining additional exclusive, worldwide licenses from The Scripps Research Institute to novel markers on the cell surface identified by Dr. Sarvetnick and her research team as being unique to the pancreas islet stem cell for which we have now filed a US patent application. In collaboration with Dr. Sarvetnick, we continue to advance the discovery program directed at the identification, isolation and culturing of pancreas stem and progenitor cells utilizing this technology. 28 LIVER STEM CELLS DISCOVERY RESEARCH PROGRAMS We initiated our discovery work for the liver stem and progenitor cell through a sponsored research agreement with Markus Grompe, Ph.D., of Oregon Health Sciences University. Dr. Grompe's work focuses on the discovery and development of a suitable method for identifying and assessing liver stem and progenitor cells for use in transplantation. We have also obtained a worldwide exclusive license to a novel mouse model of liver failure for evaluating cell transplantation developed by Dr. Grompe. Approximately 1 in 10 Americans suffers from diseases and disorders of the liver for which there are currently no effective, long-term treatments. In 1998, our researchers continued to advance methods for establishing enriched cell populations suitable for transplantation in preclinical animal models. We are focused on discovering and utilizing our proprietary methods to identify, isolate and culture liver stem and progenitor cells and to evaluate these cells in preclinical animal models. In 1999, our researchers devised a culture assay that we will use in our efforts to identify liver stem and progenitor cells. In addition to supporting the growth of an early human liver bipotent progenitor cell, it is also possible to infect this culture with human hepatitis virus, providing a valuable system for study of the virus. This technology could also provide a unique IN VITRO model for the testing of drugs that act on, or are metabolized by, human liver cells. An important element of our stem cell discovery program is the further development of intellectual property positions with respect to stem and progenitor cells. We have also obtained rights to certain inventions relating to stem cells from, and are conducting stem cell related research at, several academic institutions. We expect to expand our search for new stem and progenitor cells and to seek to acquire rights to additional inventions relating to stem and progenitor cells from third parties. WIND-DOWN OF ENCAPSULATED CELL THERAPY RESEARCH AND DEVELOPMENT PROGRAMS Until mid-1999, we engaged in research and development in encapsulated cell therapy technology, or ECT, including a pain control program funded by AstraZeneca Group plc. The results from the 85-patient double-blind, placebo-controlled trial of our encapsulated bovine cell implant for the treatment of severe, chronic pain in cancer patients did not, however, meet the criteria AstraZeneca had established for continuing trials for the therapy, and in June 1999, AstraZeneca terminated the collaboration. Consequently, in July 1999, we announced plans for the restructuring of our research operations to abandon all further ECT research and to concentrate our resources on the research and development of our proprietary platform of stem cell technology. We reduced our workforce by approximately 68 full-time employees who had been focused on ECT programs, wound down our research and manufacturing operations in Lincoln, Rhode Island, and relocated our remaining research and development activities, and our corporate headquarters, to the facilities of our wholly owned subsidiary, StemCells California, Inc., in Sunnyvale, California. We are actively seeking to sublease, assign or sell our interest in our former corporate headquarters building and our pilot manufacturing and cell processing facility in Rhode Island. In December 1999 we sold our intellectual property assets related to our ECT to Neurotech S.A., a privately held French company, in exchange for a payment of $3 million, royalties on future product sales, and a portion of certain revenues Neurotech may in the future receive from third parties. We retained certain non-exclusive rights to use the ECT in combination with our proprietary stem cell technology, and in the field of vaccines for prevention and treatment of infectious diseases. 29 In a related development, by mutual consent we and the Advanced Technology Program of the National Institute of Standards and Technology terminated two grants previously awarded to us for our encapsulated cell therapy and stem cell-related research. The encapsulated cell therapy grant was obviated by the sale of equity or convertible debt securities. To the technology to Neurotech. The funding agency has invited us to resubmit a proposal consistent with the new directions we are taking in our research and development of our platform of stem cell technologies. SUBSIDIARY STEMCELLS CALIFORNIA, INC. On September 26, 1997, we acquired by merger StemCells, Inc. (now StemCells California, Inc.), a California corporation, in exchange for 1,320,691 shares of our common stock and options and warrants for the purchase of 259,296 common shares. Simultaneously with the acquisition, its President, Richard M. Rose, M.D., became our President, Chief Executive Officer and a director, and Irving L. Weissman, M.D., a founder of the California corporation, became a member of our board of directors. We, as the sole stockholder of our subsidiary, voted on February 23, 2000, to amend its Certificate of Incorporation to change its name to StemCells California, Inc. CORPORATE INVESTMENT In July 1996, we, together with certain founding scientists, established Modex Therapeutics SA, a Swiss biotherapeutics company, to pursue extensions of our former technology of ECT for certain applications outside the central nervous system. Modex, headquartered in Lausanne, Switzerland, was formed to integrate technologies developed by us and by several other institutions to develop products to treat diseases such as diabetes, obesity and anemia. After our disposition of the encapsulated cell technology in December 1999, we no longer had common research or development interests with Modex, but we held approximate 17% of its stock. Modex completed an initial public offering on June 23, 2000, in the course of which we realized a gain of approximately $1.4 million fromextent that additional capital is raised through the sale of certain shares. After Modex's IPO, we owned 126,193 shares,equity or approximately 9%, of Modex's equity, subject to a lockup until December 23, 2000. The closing market price of Modex stock on the Swiss Neue Market exchange on January 2, 2001 was 210.00 Swiss francs, or approximately $130.39, per share. On January 9, 2001, we sold 22,616 Modex shares for a net price of 182.00 Swiss francs per share, which converts to $112.76 per share, for total proceeds of $2,550,230.27. In connection with this sale, we agreed not to resell any more of our remaining 103,577 Modex shares until April 12, 2001. LICENSE AGREEMENTS AND SPONSORED RESEARCH AGREEMENTS We have entered into a number of license agreements with commercial and non-profit institutions, as well as a number of research-plus-license agreements with academic organizations. The research agreements provide that we will fund certain research costs, and in return, will have a license or an option for a license to the resulting inventions. Under the license agreements, we will typically be subject to obligations of due diligence and the requirement to pay royalties on products that use patented technology licensed under such agreements. NEUROSPHERES, LTD. In March 1994, we entered into a Contract Research and License Agreement with NeuroSpheres, Ltd., which was clarified in a License Agreement dated as of April 1, 1997. Under the agreement as clarified, we obtained an exclusive patent license from NeuroSpheres in the field of transplantation, subject to a limited right of NeuroSpheres to purchase a nonexclusive license from us, which right was not exercised and has expired. We have developed additional intellectual property relating to the subject matter of the license. We entered into an additional license agreement with 30 NeuroSpheres as of October 30, 2000, under which we obtained an exclusive license in the field of non-transplant uses, such as drug discovery and drug testing, so that together the licenses are exclusive for all uses of the technology. We made up-front payments to NeuroSpheres of 65,000 shares of our common stock and $50,000, and we will make additional cash payments when milestones are achieved in the non-transplant field, or in any products employing NeuroSpheres patents for generating cells of the blood and immune system from neural stem cells. Milestone payments would total $500,000 for each product that is approved for market. Our agreements with NeuroSpheres will terminate at the expiration of all patents licensed to us, but can terminate earlier if we breach without curing our obligations under the agreement or if we declare bankruptcy. We would have a security interest in the licensed technology in the event that NeuroSpheres declares bankruptcy. SIGNAL PHARMACEUTICALS, INC. In December 1997, we entered into two license agreements with Signal Pharmaceuticals, Inc. under which each party licensed to the other certain patent rights and biological materials for use in defined fields. An initial disagreement as to the interpretation of the licensed rights was resolved by the parties, and the agreements are operating in accordance with their terms. Signal has now been acquired by Celgene. Each agreement with Signal will terminate at the expiration of all patents licensed under it, but the licensing party can terminate earlier if the other party breaches its obligations under the agreement or declares bankruptcy. Also, the party receiving the license can terminate the agreement at any time upon notice to the other party. Under these agreements, we must reimburse Signal for payments it must make to the University of California based on products we develop and for 50% of certain other payments Signal must make. SPONSORED RESEARCH AGREEMENTS Under Sponsored Research Agreements with The Scripps Research Institute and Oregon Health Sciences University, we funded certain research in return for licenses or options to license the inventions resulting from the research. We have also entered into license agreements with the California Institute of Technology. All of these agreements relate largely to stem or progenitor cells and or to processes and methods for the isolation, identification, expansion or culturing of stem or progenitor cells. Our research agreement with Scripps expired on November 14, 2000 and we are negotiating with Scripps to extend the term of this agreement or to enter into a new agreement. As of the date of this prospectus, we have not yet completed our negotiations with Scripps and we cannot give any assurance that our negotiations will be successful. If we are unable to extend the term of this agreement, we will have to find a replacement to perform this research or we will have to perform this research ourselves. In either case, we may experience delay and additional expense in connection with this research effort. Our license agreements with Scripps will terminate upon expiration, revocation or invalidation of the patents licensed to us, unless governmental regulations require a shorter term. These license agreements also will terminate earlier if we breach without curing our obligations under the agreement or if we declare bankruptcy, and we can terminate the license agreements at any time upon notice. Upon the initiation of the Phase II trial for our first product using Scripps licensed technology, we must pay Scripps $50,000 and upon completion of that Phase II trial we must pay Scripps an additional $125,000. Upon approval of the first product for sale in the market, we must pay Scripps $250,000. Our license agreements with the California Institute of Technology will expire upon expiration, revocation, invalidation or abandonment of the patents licensed to us. We can terminate any of these license agreements by giving 30 days' notice to the California Institute of Technology. Either party can terminate these license agreements upon a material breach by the other party. We paid $10,000 to the California Institute of Technology upon execution of the license agreements, and we must pay an additional $10,000 uponconvertible debt securities, the issuance of the patent licensed to us under the relevant agreement. We 31 also will pay $5,000 on the anniversary of the issuance of the patent licensed to us under the relevant agreement. These amounts are creditable against royalties we must pay under the license agreements. The maximum royalties that we will have to pay to the California Institute of Technology will be $2 million per year, with an overall maximum of $15 million. Once we pay the $15 million maximum royalty, the licenses will become fully paid and irrevocable. MANUFACTURING The keys to successful commercialization of brain stem and progenitor cells are efficacy, safety, consistency of the product, and economy of the process. We expect to address these issues by appropriate testing and banking representative vials of large-scale cultures. Commercial production is expected to involve expansion of banked cells and packaging themsecurities could result in appropriate containers after formulating the cells in an effective carrier. The carrier may also be used to improve the stability and acceptance of the stem cells or their progeny. Because of the early stage of our stem and progenitor cell programs, all of the issues that will affect manufacture of stem and progenitor cell products are not yet clear. MARKETING We expect to market and sell our products primarily through co-marketing, licensing or other arrangements with third parties. There are a number of substantial companies with existing distribution channels and large marketing resources who are well equipped to market and sell our products. It is our intent to have the marketing of our products undertaken by such partners, although we may seek to retain limited marketing rights in specific narrow markets where the product may be addressed by a specialty or niche sales force. PATENTS, PROPRIETARY RIGHTS AND LICENSES We believe that proprietary protection of our inventions will be of major importancefurther dilution to our future business. We have an aggressive program of vigorously seeking and protecting our intellectual property which we believe might be useful in connection with our products. We believe that our know-how will also provide a significant competitive advantage, and we intend to continue to develop and protect our proprietary know-how. We may also from time to time seek to acquire licenses to important externally developed technologies. We have exclusive or non-exclusive rights to a portfolio of patents and patent applications related to various stem and progenitor cells and methods of deriving and using them. These patents and patent applications relate mainly to compositions of matter, methods of obtaining such cells, and methods for preparing, transplanting and utilizing such cells. Currently, our U.S. patent portfolio in the stem cell therapy area includes nineteen issued U.S. patents, six of which have issued within the last year. An additional thirteen patent applications are pending, one of which has been allowed. We own or have filed patent applications which have been published for the following U.S. patents: Patent Number 5,968,829 (Human CNS neural stem cells); Patent Number 6,103,530 (Human CNS neural stem cells--culture media); Application Number WO 99/11758 (Cultures of human CNS neural stem cells); and Application Number WO 00/36091 (An animal model for identifying a common stem/progenitor to liver cells and pancreatic cells). We have licensed the following patents or pending patent applications from Neurospheres Holdings Ltd.: Patent Number 5,851,832 (In vitro proliferation); Patent Number 5,750,376 (In vitro genetic modification); Patent Number 5,981,165 (In vitro production of dopaminergic cells from mammalian central nervous system multipotent stem cell compositions); Patent Number 6,093,531 (Generation of hematopoietic cells from multipotent neural stem cells); Application Number WO 93/01275 (Mammalian central nervous system multipotent stem cell compositions); Application Number WO 94/09119 (Remyelination using mammalian central nervous 32 system multipotent stem cell compositions); Application Number WO 94/10292 (Biological factors useful in differentiating mammalian central nervous system multipotent stem cell compositions); Application Number WO 94/16718 (Genetically engineered mammalian central nervous system multipotent stem cell compositions); Application Number WO 96/15224 (Differentiation of mammalian central nervous system multipotent stem cell compositions); and Application Number WO 96/15226 (In vitro production of dopaminergic cells from mammalian central nervous system multipotent stem cell composition). We have licensed the following patents or pending patent applications from the University of California, San Diego: Patent Number 5,776,948 (Method of production of neuroblasts); Patent Number 6,013,521 (Method of production of neuroblasts); Patent Number 6,020,197 (Method of production of neuroblasts); and Application Number WO 94/16059 (Method of production of neuroblasts). We have licensed the following patents or pending patent applications from the California Institute of Technology: Patent Number 5,629,159 (Immortalization and disimmortalization of cells); Application Number WO 96/40877 (Immortalization and disimmortalization of cells); Patent Number 5,935,811 (Neuron restrictive silencer factor proteins); Application Number WO 96/27665 (Neuron restrictive silencer factor proteins); Patent Number 5,589,376 (Mammalian neural crest stem cells); Patent Number 5,824,489 (Methods for isolating mammalian multipotent neural crest stem cells); Application Number WO 94/02593 (Mammalian neural crest stem cells); Patent Number 5,654,183 (Genetically engineered mammalian neural crest stem cells); Patent Number 5,928,947 (Mammalian multipotent neural crest stem cells); Patent Number 5,693,482 (In vitro neural crest stem cell assay); Patent Number 6,001,654 (Methods for differentiating neural stem cells to neurons or smooth muscle cells (TGFb)); Application Number WO 98/48001 (Methods for differentiating neural stem cells to neurons or smooth muscle cells (TGFb)); Patent Number 5,672,499 (Methods for immortalizing multipotent neural crest stem cells); Patent Number 5,849,553 (Immortalizing and disimmortalizing multipotent neural crest stem cells); and Patent Number 6,033,906 (Differentiating mammalian neural stem cells to glial cells using neuregulins). We also rely upon trade-secret protection for our confidential and proprietary information and take active measures to control access to that information. Our policy is to require our employees, consultants and significant scientific collaborators and sponsored researchers to execute confidentiality agreements upon the commencement of an employment or consulting relationship with us. These agreements generally provide that all confidential information developed or made known to the individual by us during the course of the individual's relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees and consultants, the agreements generally provide that all inventions conceived by the individual in the course of rendering services to us shall be our exclusive property. We have obtained rights from universities and research institutions to technologies, processes and compounds that we believe may be important to the development of our products. These agreements typically require us to pay license fees, meet certain diligence obligations and, upon commercial introduction of certain products, pay royalties. These include exclusive license agreements with NeuroSpheres, The Scripps Institute, the California Institute of Technology and the Oregon Health Sciences University, to certain patents and know-how regarding present and certain future developments in CNS and pancreas stem cells. COMPETITION The targeted disease states for our initial products in some instances currently have no effective long-term therapies. However, we do expect that our initial products will have to compete with a variety of therapeutic products and procedures. Major pharmaceutical companies currently offer a number of pharmaceutical products to treat neurodegenerative and liver diseases, diabetes and other diseases for which our technologies may be applicable. Many pharmaceutical and biotechnology 33 companies are investigating new drugs and therapeutic approaches for the same purposes, which may achieve new efficacy profiles, extend the therapeutic window for such products, alter the prognosis of these diseases, or prevent their onset. We believe that our products, when successfully developed, will compete with these products principally on the basis of improved and extended efficacy and safety and their overall economic benefit to the health care system. The market for therapeutic products that address degenerative diseases is large, and competition is intense. We expect competition to increase. We believe that our most significant competitors will be fully integrated pharmaceutical companies and more established biotechnology companies. Smaller companies may also be significant competitors, particularly through collaborative arrangements with large pharmaceutical or biotechnology companies. Many of these competitors have significant products approved or in development that could be competitive with our potential products. Competition for our stem and progenitor cell products may be in the form of existing and new drugs, other forms of cell transplantation, ablative and simulative procedures, and gene therapy. We believe that some of our competitors are also trying to develop stem and progenitor cell-based technologies. We expect that all of these products will compete with our potential stem and progenitor cell products based on efficacy, safety, cost and intellectual property positions. We may also face competition from companies that have filed patent applications relating to the use of genetically modified cells to treat disease, disorder or injury. We may be required to seek licenses from these competitors in order to commercialize certain of our proposed products. Once our products are developed and receive regulatory approval, they must then compete for market acceptance and market share. For certain of our potential products, an important success factor will be the timing of market introduction of competitive products. This is a function of the relative speed with which we and our competitors can develop products, complete the clinical testing and approval processes, and supply commercial quantities of a product to market. These competitive products may also impact the timing of clinical testing and approval processes by limiting the number of clinical investigators and patients available to test our potential products. While we believe that the primary competitive factors will be product efficacy, safety, and the timing and scope of regulatory approvals, other factors include, in certain instances, obtaining marketing exclusivity under the Orphan Drug Act, availability of supply, marketing and sales capability, reimbursement coverage, price, and patent and technology position. GOVERNMENT REGULATION Our research and development activities and the future manufacturing and marketing of our potential products are, and will continue to be, subject to regulation for safety and efficacy by numerous governmental authorities in the United States and other countries. In the United States, pharmaceuticals, biologicals and medical devices are subject to rigorous Food and Drug Administration, or FDA, regulation. The Federal Food, Drug and Cosmetic Act, as amended, and the Public Health Service Act, as amended, the regulations promulgated thereunder, and other Federal and state statutes and regulations govern, among other things, the testing, manufacture, safety, efficacy, labeling, storage, export, record keeping, approval, marketing, advertising and promotion of our potential products. Product development and approval within this regulatory framework takes a number of years and involves significant uncertainty combined with the expenditure of substantial resources. In addition, the federal, state, and other jurisdictions have restrictions on the use of fetal tissue. 34 FDA APPROVAL The steps required before our potential products may be marketed in the United States include: STEPS CONSIDERATIONS 1. Preclinical laboratory and animal tests Preclinical tests include laboratory evaluation of the product and animal studies in specific disease models to assess the potential safety and efficacy of the product and our formulation as well as the quality and consistency of the manufacturing process. 2. Submission to the FDA of an application The results of the preclinical tests are for an Investigational New Drug Exemption, or submitted to the FDA as part of an IND, and IND, which must become effective before U.S. the IND becomes effective 30 days following human clinical trials may commence its receipt by the FDA, as long as there are no questions, requests for delay or objections from the FDA. 3. Adequate and well-controlled human Clinical trials involve the evaluation of the clinical trials to establish the safety and product in healthy volunteers or, as may be efficacy of the product the case with our potential products, in a small number of patients under the supervision of a qualified physician. Clinical trials are conducted in accordance with protocols that detail the objectives of the study, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Any product administered in a U.S. clinical trial must be manufactured in accordance with clinical Good Manufacturing Practices, or cGMP, determined by the FDA. Each protocol is submitted to the FDA as part of the IND. The protocol for each clinical study must be approved by an independent Institutional Review Board, or IRB, at the institution at which the study is conducted and the informed consent of all participants must be obtained. The IRB will consider, among other things, the existing information on the product, ethical factors, the safety of human subjects, the potential benefits of the therapy and the possible liability of the institution. Clinical development is traditionally conducted in three sequential phases, which may overlap: - In Phase I, products are typically introduced into healthy human subjects or into selected patient populations to test for adverse reactions, dosage tolerance, absorption and distribution, metabolism, excretion and clinical pharmacology.
35 - Phase II involves studies in a limited patient population to (i) determine the efficacy of the product for specific targeted indications and populations, (ii) determine optimal dosage and dosage tolerance and (iii) identify possible adverse effects and safety risks. When a dose is chosen and a candidate product is found to be effective and to have an acceptable safety profile in Phase II evaluations, Phase III trials begin. - Phase III trials are undertaken to conclusively demonstrate clinical efficacy and to test further for safety within an expanded patient population, generally at multiple study sites. The FDA continually reviews the clinical trial plans and results and may suggest changes or may require discontinuance of the trials at any time if significant safety issues arise. 4. Submission to the FDA of marketing The results of the preclinical studies and authorization applications clinical studies are submitted to the FDA in the form of marketing approval authorization applications. 5. FDA approval of the application(s) prior The testing and approval process will require to any commercial sale or shipment of the substantial time, effort and expense. The drug. Biologic product manufacturing time for approval is affected by a number of establishments located in certain states also factors, including relative risks and may be subject to separate regulatory and benefits demonstrated in clinical trials, the licensing requirement availability of alternative treatments and the severity of the disease. Additional animal studies or clinical trials may be requested during the FDA review period which might add to that time.
After FDA approval for the initial indications and requisite approval of the manufacturing facility, further clinical trials may be required to gain approval for the use of the product for additional indications. The FDA may also require unusual or restrictive post-marketing testing and surveillance to monitor for adverse effects, which could involve significant expense, or may elect to grant only conditional approvals. FDA MANUFACTURING REQUIREMENTS Among the conditions for product licensure is the requirement that the prospective manufacturer's quality control and manufacturing procedures conform to the FDA's cGMP requirement. Even after product licensure approval, the manufacturer must comply with cGMP on a continuing basis, and what constitutes cGMP may change as the state of the art of manufacturing changes. Domestic manufacturing facilities are subject to regular FDA inspections for cGMP compliance which are normally held at least every two years. Foreign manufacturing facilities are subject to periodic FDA inspections or inspections by the foreign regulatory authorities with reciprocal inspection agreements with the FDA. Domestic manufacturing facilities may also be subject to inspection by foreign authorities. ORPHAN DRUG ACT The Orphan Drug Act provides incentives to drug manufacturers to develop and manufacture drugs for the treatment of diseases or conditions that affect fewer than 200,000 individuals in the United States. Orphan drug status can also be sought for treatments for diseases or conditions that 36 affect more than 200,000 individuals in the United States if the sponsor does not realistically anticipate its product becoming profitable from sales in the United States. We may apply for orphan drug status for certain of our therapies. Under the Orphan Drug Act, a manufacturer of a designated orphan product can seek tax benefits, and the holder of the first FDA approval of a designated orphan product will be granted a seven-year period of marketing exclusivity in the United States for that product for the orphan indication. While the marketing exclusivity of an orphan drug would prevent other sponsors from obtaining approval of the same compound for the same indication, it would not prevent other types of products from being approved for the same use including, in some cases, slight variations on the originally designated orphan product. PROPOSED FDA REGULATIONS Proposed regulations of the FDA and other governmental agencies would place restrictions, including disclosure requirements, on researchers who have a financial interest in the outcome of their research. Under the proposed regulations, the FDA could also apply heightened scrutiny to, or exclude the results of, studies conducted by such researchers when reviewing applications to the FDA, which contain such research. Certain of our collaborators have stock options or other equity interests in us that could subject such collaborators and us to the proposed regulations. Our research and development is based on the use of human stem and progenitor cells. The FDA has published a "Proposed Approach to Regulation of Cellular and Tissue-Based Products" which relates to the use of human cells. We cannot now determine the effects of that approach or what regulatory actions might be taken from it. Restrictions exist on the testing or use of cells, whether human or non-human. OTHER REGULATIONS In addition to safety regulations enforced by the FDA, we are also subject to regulations under the Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act and other present and potential future foreign, Federal, state and local regulations. Outside the United States, we will be subject to regulations which govern the import of drug products from the United States or other manufacturing sites and foreign regulatory requirements governing human clinical trials and marketing approval for our products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursements vary widely from country to country. In particular, the European Union, or EU, is revising its regulatory approach to high tech products, and representatives from the United States, Japan and the EU are in the process of harmonizing and making more uniform the regulations for the registration of pharmaceutical products in these three markets. 37 QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK On December 29, 2000, our investment in 126,193 shares of Modex Therapeutics Ltd. Stock was valued at $16,356,333 based on the per share price of $129.61, which we converted from a market price of 210.00 Swiss francs. Our value in this investment is subject to both equity price risk and foreign currency exchange risk. Modex shares were offered in an IPO on the Swiss Neue Market on June 23, 2000 at a price of 168.00 Swiss francs. From the date of the IPO to the date of this prospectus, the Modex closing share price has fluctuated from a low of 150.50 Swiss francs on January 16, 2001 to a high of 390.00 Swiss francs on October 6, 2000. The market price of the Modex stock on January 2, 2001 was 210.00 Swiss francs, which converts to $130.39 using exchange rates on that date, which represents an estimated fair market value of $16,453,825 for our holdings on that date. On January 9, 2001, we sold 22,616 Modex shares for a net price of 182.00 Swiss francs per share, which converts to $112.76 per share, for total proceeds of $2,550,230.27. In connection with this sale, we agreed not to resell any more of our Modex shares until April 12, 2001. If we were to seek to liquidate all or part of our remaining 103,577 Modex shares, our proceeds would depend on the share price and foreign currency exchange rates at the time of conversion. Additionally, if we sell a sizable portion of our holdings, we may have to sell these shares at a discount to market price. The company's sole market risk sensitive instrument is:
MARKET VALUE EXPECTED ASSOCIATED AT DECEMBER 29, FUTURE NO. OF SHARES DESCRIPTION RISKS 2000 CASH FLOWS 126,193 Modex Equity/Foreign $16,356,333 (1) Therapeutics Currency Translation
- ------------------------ (1) Although we have not formally adopted a liquidation plan for this investment, liquidation may be necessary to meet operating cash flow requirements. Under the agreement with Modex, we had been restricted from selling our holding through December 23, 2000 and, as noted above, we sold 22,616 shares on January 9, 2001 and agreed not to sell any more shares until April 12, 2001. If we sell some but not all of our remaining 103,577 shares, we likely would have to agree, in connection with the sale, to refrain from selling additional shares for several months. REIMBURSEMENT AND HEALTH CARE COST CONTROL Reimbursement for the costs of treatments and products such as ours from government health administration authorities, private health insurers and others both in the United States and abroad is a key element in the success of new health care products. Significant uncertainty often exists as to the reimbursement status of newly approved health care products. The revenues and profitability of some health care-related companies have been affected by the continuing efforts of governmental and third party payers to contain or reduce the cost of health care through various means. Payers are increasingly attempting to limit both coverage and the level of reimbursement for new therapeutic products approved for marketing by the FDA, and are refusing, in some cases, to provide any coverage for uses of approved products for disease indications for which the FDA has not granted marketing approval. For example, in certain foreign markets, pricing or profitability of prescription pharmaceuticals is subject to government control. In the United States, there have been a number of Federal and state proposals to implement government control over health care costs. 38 EMPLOYEES As of December 31, 2000, we had twenty-six full-time employees, of whom six have Ph.D. degrees, as well as two half-time employees. The equivalent of fifteen full-time employees work in research and development and laboratory support services. A number of our employees have held positions with other biotechnology or pharmaceutical companies or have worked in university research programs. No employees are covered by collective bargaining agreements. SCIENTIFIC ADVISORY BOARD Members of our Scientific Advisory Board provide us with strategic guidance in regard to our research and product development programs, as well as assistance in recruiting employees and collaborators.

In the event Dr. Schwartz devotes more than thirty business days in any calendar quarter to the performance of his duties, Dr. Schwartz is entitled to receive additional compensation at the rate of $1,500 per day. Under the Letter Agreement, Dr. Schwartz was granted a stock option covering 40,000 shares of Common Stock that vests in equal portions on the last day of each of the 29 months of the term of the Letter Agreement. By virtue of provisions incorporated from the Consulting Services Agreement, Dr. Schwartz also holds an option to purchase 76,000 shares of the Company's Common Stock at $1.281 per share, the fair market value of the Company's Common Stock at the time the option was granted, vesting at a rate of 3,167 shares per month for the ensuing 23 months after the date of the grant, with a final vesting of 3,159 shares in the 24th month, plus another optionthis prospectus, we are authorized to purchase 48,000issue up to 221,000,000 shares of Common Stock at the then current fair marketcapital stock, par value of the Company's Common Stock on July 27, 1999, vesting at a rate of 2,000 shares per month. In the event Dr. Schwartz ceases to be Chairman of the Board of Directors, either as a result of an affirmative vote of the Board of Directors for reasons other than cause or due to his disability or his resignation from such position, but remains a Director, his cash compensation and remaining unvested portion of the 40,000-share time-based stock option will be reduced to the then current rate for a Director of the Company, plus $5,000 per month pursuant to the Consulting Services Agreement. In the event Dr. Schwartz ceases to be Chairman of the Board of Directors, either as a result of an affirmative vote of the Board of Directors for reasons other than cause or due to his disability or his resignation from such position, and then he resigns as a Director or is removed as a Director pursuant to the Company's By-laws, the Company shall have no further obligation to pay cash compensation to Dr. Schwartz under the Letter Agreement but he would receive $5,000 per month pursuant to the Consulting Services Agreement. Dr. Schwartz shall have one year from such date to exercise the vested portion of the 40,000-share time-based option and any unvested portion of that option shall lapse. In the event Dr. Schwartz is removed from his positions as Director and Chairman of the Board of Directors for cause, as defined in the Letter Agreement, the Company shall have no further obligation to pay cash compensation to Dr. Schwartz under the Letter Agreement, any unvested portion of the 40,000-share time-based option shall lapse and the exercise of any vested portion shall be governed by the terms of the Company's 1992 Equity Incentive Plan.

To effectuate the intention of Dr. Schwartz and other members of the Board to change the form but not the amount of compensation, Dr. Schwartz will be granted options covering a number of shares of the Company's common stock such that the difference between the aggregate exercise price of such options and the aggregate market value of the shares underlying such options (using the closing price of the Company's common stock for the date of the subject Board or Committee meeting (if such Committee meeting is not held contemporaneously with a Board meeting) or, with respect to the quarterly or monthly retainer payments of $33,000 and $5,000 respectively, the closing price for the last business day of the quarter or month) is equal to the compensation he is entitled to receive.

Dr. Weissman, a member of the Board of Directors, was retained in September 1997 to serve as a consultant to us.

Originally, the remainder of the option would have vested upon the occurrence of certain milestones related to the Company's stem cell research program and in the event of certain changes of control. We agreed to amend the option on October 27, 2000 so that theauthorized, 220,000,000 shares would become exercisable over eight years from the original grant date (so the option is currently exercisable for 200,000 shares) or in the event of certain changes of control.

The Consulting Agreement contains confidentiality, noncompetition, and assignment of invention provisions and is for a term of fifteen years, subject to earlier termination by us for cause or frustration of purpose and earlier termination by Dr. Weissman for good reason.

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 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.

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.

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.

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 sold from timehigher than the price that might otherwise exist in the open market. Neither we nor the underwriter make any representation or prediction as to time by the selling stockholders, or by pledgees, donees, transferees or other successors in interest (i) to or through underwriters or dealers, (ii) directly to one or more other purchasers, (iii) through agentseffect that the transactions described above may have on a best-efforts basis, or (iv) through a combinationthe price of any such methods of sale.

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 our opinion,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.

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 referredcannot 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 above present fairly, in all material respects,its Restated Certificate of Incorporation with the consolidated financial positionSecretary of StemCells, Inc. (formerly CytoTherapeutics, Inc.) at December 31, 1999 and 1998, and the consolidated results of its operations and its cash flows for eachState of the three yearsState 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 period ended December 31, 1999,accompanying financial statements and notes thereto have been adjusted to reflect the Reverse Split on a retroactive basis.

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:

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.

See accompanying

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.

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. F-4 STEMCELLS, INC.

See accompanying notes

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-5 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.

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”) CONSOLIDATED STATEMENTS OF CASH FLOWS 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.

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”).

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.

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.

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.

The remaining outstanding warrants and terms as of December 31, 2017 and 2016 is as follows:

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 stock51 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.

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.

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 receivablefinancial loss in the amount of $3,000,000$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.

(*) 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.

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 intangible assets. See accompanying notesfederal tax rate of 21% from January 1, 2018 and onward.

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 consolidated financial statements. F-6 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1999 1. NATURE OF BUSINESS StemCells, Inc. (formerly CytoTherapeutics, Inc.) (the "Company")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.

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 StemCells California, Inc.Plan of Merger, dated August 15, 2016, with Microbot Medical Ltd., a wholly owned subsidiary. Significant intercompany accounts have been eliminatedprivate medical device company organized under the laws of the State of Israel (“Microbot Israel”). On the same day and in consolidation. USE OF ESTIMATES 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 the consolidated financial statements in conformity with generally accepted accounting principlesU.S. GAAP requires management to make estimates and assumptions that affectpertaining to transactions and matters whose ultimate effect on the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. CASH EQUIVALENTS AND MARKETABLE SECURITIES Cash equivalents include funds held in investments with original maturities of three months or less when purchased. The Company's policy regarding selection of investments, pending their use, is to ensure safety, liquidity, and capital reservation while obtaining a reasonable rate of return. Marketable securities consist of investments in agencies of the U.S. government, investment grade corporate notes and money market funds. The fair values for marketable securities are based on quoted market prices. The Company determines the appropriate classification of cash equivalents and marketable securitiescannot precisely be determined at the time of purchase and reevaluates such designation asfinancial statements preparation. Although these estimates are based on management’s best judgment, actual results may differ from these estimates.

D.ReverseStock Split

On September 4, 2018, the Company filed a Certificate of each balance sheet date. The Company classifies such holdings as available-for-sale securities, which are carried at fair value,Amendment to its Restated Certificate of Incorporation with unrealized gains and losses reported asthe Secretary of State of the State of Delaware to affect a separate componentone-for-15 reverse stock split of stockholders' equity. PROPERTY HELD FOR SALEthe Company’s common stock (the “Reverse Split”). As a result of the Company's decisionReverse 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 exit the encapsulated cell technologynearest whole number. The Reverse Split automatically and relocate its corporate headquartersproportionately 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 Sunnyvale, CA, certain property considered by managementnumbers of shares of common stock and per share data in the accompanying financial statements and notes thereto for periods ended prior to no longer be necessary hasSeptember 4, 2018 have been made available for sale or lease. The aggregate carrying value of such property has been reviewed by management, subjectadjusted to appraisal and adjusted downward to estimated market value. F-7 STEMCELLS, INC.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment, including that held under capitalized lease obligations, is stated at cost and depreciated using

The significant accounting policies applied in the straight-line method over the estimated lifepreparation of the respective asset, as follows: Building and improvements................................... 3 -- 15 years Machinery and equipment..................................... 3 -- 10 years Furniture and fixtures...................................... 3 -- 10 years
PATENT COSTS The Company capitalizes certain patent costs related to patent applications. Accumulated costs are amortized over the estimated economic life of the patents, not to exceed 17 years, using the straight-line method, commencing at the time the patent is issued. Costs related to patent applications are written off to expense at the time such patents are deemed to have no continuing value. At December 31, 1999 and 1998, total costs capitalized were $718,000 and $4,285,000 and the related accumulated amortization were $9,000 and $347,000, respectively. Patent expense totaled $539,000, $3,000, and $365,000 in 1999, 1998 and 1997, respectively. In December 1999, the Company sold its Encapsulated Cell Technology ("ECT") to Neurotech, S.A. for an initial payment of $3,000,000, royalties on future product sales, and a portion of certain Neurotech revenues from third parties, in return for the assignment to Neurotech of intellectual property assets relating to ECT. In addition, the Company retained certain non-exclusive rights to use ECT in combination with its proprietary stem cell technology and in the field of vaccines for prevention and treatment of infectious diseases. The patent portfolio that was sold had a net book value of $3,180,000. The loss on this transaction and expenses related to the write-down of ECT are included in wind-down expenses on the Company's Consolidated Statement of Operations. STOCK BASED COMPENSATION The Company grants qualified stock options for a fixed number of shares to employees with an exercise price equal to the fair market value of the shares at the date of grant. The Company accounts for stock option grants in accordance with APB Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and, accordingly, recognizes no compensation expense for qualified stock option grants. For certain non-qualified stock options granted to non-employees, the Company accounts for these grants in accordance with FAS No. 123--ACCOUNTING FOR STOCK-BASED COMPENSATION and EITF96-18--ACCOUNTING FOR EQUITY INSTRUMENTS THAT ARE ISSUED TO OTHER THAN EMPLOYEES FOR ACQUIRING, OR IN CONJUNCTION WITH SELLING, GOODS OR SERVICES, and accordingly, recognizes as consulting expenses the estimated fair value of such options as calculated using the Black-Scholes valuation model. Fair value is determined using methodologies allowable by FAS No. 123. The cost is amortized over the vesting period of each option or the recipient's contractual arrangement, if shorter. F-8 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) INCOME TAXES The liability method is used to account for income taxes. Deferred tax assets and liabilities are determined based on differences between financial reporting and income tax bases of assets and liabilities, as well as net operating loss carry forwards, and are measured using the enacted tax rates and rates under laws that are expected to be in effect when the differences reverse. Deferred tax assets may be reduced by a valuation allowance to reflect the uncertainty associated with their ultimate realization. REVENUE FROM COLLABORATIVE AGREEMENTS Revenues from collaborative agreements are recognized as earned upon either the incurring of reimbursable expenses directly related to the particular research plan or the achievement of certain development milestones as defined within the terms of the collaborative agreement. Payments received in advance of research performed are designated as deferred revenue. Recorded revenues are not refundable in the event research efforts are considered unsuccessful. RESEARCH AND DEVELOPMENT COSTS The company expenses all research and development costs as incurred. NET LOSS PER SHARE Net loss per share is computed using the weighted average number of shares of common stock outstanding. Common equivalent shares from stock options and warrants are excluded, as their effect is antidilutive. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS The Securities Exchange Commission's recently issued Staff Accounting Bulletin No. 101 provides guidance on revenue recognition that may impact the Company's future reporting relative to recognizing revenues received from collaborative and similar agreements. The Company does not expect this guidance to result in significant changes to its existing revenue recognition policy, subject to the specific terms of each individual collaborative agreement. 3. SALE OF 6% CUMULATIVE CONVERTIBLE PREFERRED STOCK On April 13, 2000, the Company completed arrangements to sell 1,500 shares of 6% cumulative convertible preferred stock plus a warrant for 75,000 shares of the Company's common stock to two members of its Board of Directors for $1,500,000, on terms more favorable to the Company than it was then able to obtain from outside investors. The shares are convertible at the option of the holders into common stock at $3.77 per share (based on the face value of the preferred shares). The conversion price may be below the trading market price of the stock at the time of conversion. The Company has valued the beneficial conversion feature using the intrinsic value method reflecting the April 13, 2000 commitment date and the most beneficial per share discount available to the preferred shareholders. Such value was $265,000 and will be treated as a deemed dividend as of the commitment date. The holders of the preferred stock have liquidation rights equal to their original investment plus accrued F-9 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 3. SALE OF 6% CUMULATIVE CONVERTIBLE PREFERRED STOCK (CONTINUED) but unpaid dividends. The investors would be entitled to make additional investments in the Company on the same terms as those on which the Company completes offerings of its securities with third parties within 6 months, if any such offerings are completed. If offerings totaling at least $6 million are not completed during the 6 months, the investors have the right to acquire up to 1,126 additional shares of convertible preferred stock at $6.33 per share. Any unconverted preferred stock is converted (based on the face value of the shares), at the applicable conversion price, on April 13, 2002 in the case of the original stock and two years after the first acquisition of any of the additional 1,126 shares, if any are acquired. The warrant expires on April 13, 2005. 4. WIND-DOWN OF ENCAPSULATED CELL TECHNOLOGY RESEARCH AND DEVELOPMENT PROGRAM Until mid-1999, the Company engaged in research and development in encapsulated cell therapy technology, including a pain control program funded by AstraZeneca Group plc. The results from the 85-patient double-blind, placebo-controlled trial of our encapsulated bovine cell implant for the treatment of severe, chronic pain in cancer patients did not, however, meet the criteria AstraZeneca had established for continuing trials for the therapy, and in June 1999 AstraZeneca terminated the collaboration, as allowed under the terms of the original collaborative agreement signed in 1995. As a result of termination, management determined in July 1999 to restructure its research operations to abandon all further encapsulated cell technology research and concentrate its resources on the research and development of its proprietary platform of stem cell technologies. The Company wound down its research and manufacturing operations in Lincoln, Rhode Island, and relocated its remaining research and development activities, and its corporate headquarters, to the facilities of its wholly owned subsidiary, StemCells California, Inc., in Sunnyvale, California, in October 1999. The Company terminated legal, professional and consulting contractual arrangements in support of ECT research. The Company had used these legal, professional and consulting contractual arrangements to meet regulatory requirements in support of its research work, to support contractual arrangements with clinical sites, to provide assistance at clinical sites in administrating therapy and documenting activities, and to assist in compliance with FDA and other regulations regarding its clinical trials. ECT related patent law work was also terminated. The Company also engaged professional consultants in connection with the determination to exit its ECT activities and restructure its operations, which concluded with the exit from ECT activities and relocation of its corporate headquarters to California. The Company reduced its workforce by approximately 58 employees who had been focused on ECT programs and 10 administrative employees. As a result, the Company sold excess furniture and equipment in December 1999 and is seeking to sublease the science and administrative facility and to sell the pilot manufacturing facility. Wind-down expenses totaled approximately $6,048,000 for the year ended December 31, 1999; no such expenses were incurred in 1998 and 1997. These expenses relate to the wind-down of the Company's encapsulated cell technology research and development program and the Company's other Rhode Island operations, and the transfer of the Company's corporate headquarters to Sunnyvale, California.

- ------------------------ (1) Management's estimate of the fixed asset impairment was derived from communications with an outside auction house. The patent impairment loss was based on preliminary negotiations with parties interested in acquiring the patents. (2) Facilities carrying costs include operating lease payments, utilities, property taxes, insurance, maintenance, interest and other non-employee related expenses necessary to maintaining these facilities through the expected date of disposition (June 30, 2000). (3) The Company originally received funding from the Rhode Island Partnership for Science and Technology (RIPSAT) for purposes of conducting ECT activities conditioned upon maintaining the operation within the state. RIPSAT claimed that the Company's decision to exit ECT activities and close the Rhode Island operation was in violation of the funding arrangement and that the Company was obligated to return a portion of the funding proceeds. Although the Company disputed these claims, during the fourth quarter of 1999, management determined it was in the best interest of the Company to settle the issue. (4) The Company held an auction to sell all ECT fixed assets. Proceeds from that sale resulted in a loss, which was related to machinery and equipment ($292,000), and furniture and fixtures ($26,000). F-11 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 4. WIND-DOWN OF ENCAPSULATED CELL TECHNOLOGY RESEARCH AND DEVELOPMENT PROGRAM (CONTINUED) (5) The write-down of the pilot plant was based on an independent property appraisal, which was not available during the third quarter, when the Company reached a decision to exit ECT activities and relocate the corporate headquarters. At December 31, 1999, the Company's $1.6 million wind-down reserve included approximately $1.2 million for the RIPSAT settlement and approximately $0.4 million for Rhode Island facility costs. Property held for sale at December 31, 1999, consisted of $3.2 million relating to the Company's pilot plant facility located in Lincoln, Rhode Island. The Company suspended depreciation of these assets totalling approximately $140,000 for the quarter ended December 31, 1999. The balance reflected the $300,000 write-down included as part of the additional wind-down expenses recognized during the fourth quarter, in accordance with

Unaudited Interim Financial Accounting Standards Board Statement 121, which requires that long-lived assets be reviewed for impairment whenever events or circumstances indicate that the carrying value of the asset may not be recoverable. There were no such assets at December 31, 1998. 5. STEMCELLS CALIFORNIA, INC. In September 1997, a merger of a wholly owned subsidiary of the company and StemCells California, Inc. was completed in the form of a purchase. Through the merger, the Company acquired StemCells California, Inc. for a purchase price totaling approximately $9,475,000, consisting of 1,320,691 shares of the Company's common stock, valued at $6,600,000 and options and warrants for the purchase of 259,296 common shares at nominal consideration, valued at $1,300,000, the assumption of certain liabilities of $934,000 and transaction costs of $641,000. Options and warrants were valued utilizing the intrinsic method; the resultant value approximated the value determined using the Black- Scholes method. The purchase price was allocated, based upon an asset valuation study using income approach methods, to license agreements valued at $1,131,000 to be amortized over three years and acquired research and development of $8,344,000, which was expensed. The acquired research and development had not reached scientific feasibility and had no alternative future uses. As part of the acquisition of StemCells, Richard M. Rose, M.D., became President, Chief Executive Officer and director of the Company and Dr. Irving Weissman became a director of the Company. Upon consummation of the merger, the Company entered into consulting arrangements with the principal scientific founders of StemCells: Dr. Irving Weissman, Dr. Fred H. Gage and Dr. David Anderson. Additionally, in connection with the merger, the Company was granted an option by the former shareholders of StemCells to repurchase 500,000 of the Company's shares of Common Stock exchanged for StemCells shares, upon the occurrence of certain events. To attract and retain Drs. Rose, Weissman, Gage and Anderson, and to expedite the progress of the Company's stem cell program, the Company awarded these individuals options to acquire a total of approximately 1.6 million shares of the Company's common stock, at an exercise price of $5.25 per share, the quoted market price at the grant date. Under the original grants, approximately 100,000 of these options were exercisable immediately on the date of grant, 1,031,000 of these options would vest and become exercisable only upon the achievement of specified milestones related to the Company's stem cell development program and the remaining 469,000 options would vest over eight years. The F-12 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 5. STEMCELLS CALIFORNIA, INC. (CONTINUED) expense associated with the grants that vested immediately was considered non-employee compensation and was based on the fair value of the options granted. The expense was considered immaterial. In connection with the 469,000 options issued to a non-employee, Dr. Anderson, the Company recorded deferred compensation of $1,750,000, the fair value of such options at the date of grant, which will be amortized over an eight-year period. The fair value was determined using the Black-Scholes method with the following inputs: volatility .594, expected life 8 years, dividend yield 0.0%, risk free rate 5.98%. If the milestones specified relating to the 1,031,000 option granted to non-employees Drs. Weissman and Gage are achieved, at that time the company will record compensation expense for the fair market value of such options determined using the Black-Scholes method. The company has also designated a pool of 400,000 options to be granted to persons in a position to make a significant contribution to the success of the stem cell program. Stem cell research is conducted pursuant to the provisions of an agreement between the company and Drs. Weissman and Gage providing for a two-year research plan. If the goals of the research plan are accomplished, the Company has agreed to fund continuing stem cell research. Increases in stem cells research funding of not more than 25% a year will be funded by the Company as long as the goals of the research plan are being met. However, the Company will retain the option of (i) ceasing or reducing brain stem cell research even if all research plan goals are met, but will be required to accelerate the vesting of all still-achievable performance based stock options, and (ii) ceasing or reducing non-brain stem cell research even if all plan goals are being met by affording the scientific research founders the opportunity to continue development of the non-brain stem cell research by licensing the technology related to such research to the founders in exchange for a payment to the Company equal to all prior Company funding for such research, plus royalty payments. 6. MODEX In October 1997, the Company completed a series of transactions, which resulted in the establishment of its previously 50%-owned Swiss subsidiary, Modex Therapeutics, Ltd., (Modex) as an independent company. In the transactions, the Company reduced its ownership interest from 50% to approximately 25% in exchange for $4 million cash and elimination of its prior contingent obligation to contribute an additional Sfr 2.4 million (approximately $1.7 million) to Modex in July 1998. In the transactions, all of the put and call arrangements between the Company and other stockholders of Modex were eliminated and the Company forgave $463,000 due from Modex to the Company. The Company recorded a gain on the transactions of $3,387,000. In April 1998, Modex completed an additional equity offering, in which the Company did not participate. This resulted in a reduction in the Company's ownership to less than 20% ownership; therefore, the Company accounted for this investment under the cost method at December 31, 1999. The pre-existing royalty-bearing Cross License Agreement between the Company and Modex was assigned by the Company to Neurotech S.A., a privately held French company, as part of the sale of the intellectual property assets related to the Company's encapsulated cell therapy technology to Neurotech. Under the terms of the sale to Neurotech, the Company will receive a portion of revenues Neurotech receives from Modex under the Cross License Agreement. F-13 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 7. MARKETABLE SECURITIES During 1999, the Company sold all of its remaining marketable equitable securities. At December 31, 1999, all of the Company's available funds were held in cash and cash equivalents. The following is a summary of available-for-sale securities held at December 31, 1998:

8. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment consists of the following:
DECEMBER 31, ------------------------ 1999 1998 ---------- ----------- Building and improvements........................... $ 665,890 $ 5,665,077 Machinery and equipment............................. 1,691,096 9,887,251 Furniture and fixtures.............................. 219,260 869,831 ---------- ----------- 2,576,286 16,422,159 Less accumulated depreciation and amortization...... 828,401 8,066,150 ---------- ----------- $1,747,885 $ 8,356,009 ========== ===========
Depreciation and amortization expense was $1,436,000, $1,720,000, and $1,778,000 for the years ending December 31, 1999, 1998 and 1997, respectively. As part of the Company's restructuring of its operations, sale of its encapsulated cell technology ("ECT"), and relocation of its corporate headquarters to Sunnyvale, California, the Company identified machinery and equipment and furniture and fixtures associated with the ECT or otherwise no longer needed. In December of 1999, the Company disposed of these excess fixed assets, realizing proceeds of approximately $746,000. At the time of the sale, these assets had a net book value of approximately $1,063,000 after a third quarter 1999 write-down of $800,000, which was based on management's estimate of expected sale proceeds. The third quarter write-down and actual fourth quarter loss were included in wind-down expenses. Certain property, plant and equipment have been acquired under capitalized lease obligations. These assets totaled $5,827,000 and $6,587,000, at December 31, 1999 and 1998, respectively, with related accumulated amortization of $2,747,000 and $2,860,000 at December 31, 1999 and 1998, F-14 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 8. PROPERTY, PLANT AND EQUIPMENT (CONTINUED) respectively. As a result of the Company's decision to exit ECT and relocate to Sunnyvale, CA, this property has been classified as held for sale at December 31, 1999. 9. OTHER ASSETS Other assets are as follows:
DECEMBER 31, ----------------------- 1999 1998 ---------- ---------- Patents, net......................................... $ 708,823 $3,938,755 License agreements, net.............................. 282,750 659,750 Security deposit--building lease..................... 750,000 750,000 Restricted cash...................................... -- 603,467 Deferred financing costs, net........................ 117,195 123,701 ---------- ---------- $1,858,768 $6,075,663 ========== ==========
The decrease in patents from 1999 to 1998 was primarily due to management's decision to exit encapsulated cell technology and dispose of the related intellectual property. Management reached this decision during the third quarter of 1999, and established a reserve that included $260,000 directly related to the write-down of encapsulated cell technology patents. During the fourth quarter, management established an additional reserve that included a $180,000 loss associated with the sale of encapsulated cell technology patents worth $3,180,000. At December 31, 1999 and 1998, accumulated amortization was $857,000 and $818,000, respectively, for patents and license agreements. 10. ACCRUED EXPENSES Accrued expenses are as follows:
DECEMBER 31, ----------------------- 1999 1998 ---------- ---------- Wind-down expenses................................... $1,634,522 $ -- External services.................................... 97,439 412,253 Employee compensation................................ 306,342 262,679 Collaborative research............................... 222,140 196,505 Other................................................ 344,625 148,682 ---------- ---------- $2,605,068 $1,020,119 ========== ==========
The reserve for wind-down expenses included approximately $1,172,000 relating to the RIPSAT settlement (Notes 4 and 11) and approximately $463,000 for the estimated six months of lease payments and operating costs for the Rhode Island facilities through an expected disposal date of June 30, 2000. F-15 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 11. LEASES The Company has undertaken direct financing transactions with the State of Rhode Island and received proceeds from the issuance of industrial revenue bonds totaling $5,000,000 to finance the construction of its pilot manufacturing facility. The related leases are structured such that lease payments will fully fund all semiannual interest payments and annual principal payments through maturity in August 2014. Fixed interest rates vary with the respective bonds' maturities, ranging from 5.1% to 9.5%. The bonds contain certain restrictive covenants which limit, among other things, the payment of cash dividends and the sale of the related assets. In addition, the Company was required to maintain a debt service reserve until December 1999. On March 3, 2000 the Company entered into a settlement agreement with RIPSAT, the Rhode Island Industrial Recreational Building Authority ("IRBA") and the Rhode Island Industrial Facilities Corporation ("RIIFC"). The Company agreed to pay RIPSAT $1,172,000 in full satisfaction of all obligations of the Company to RIPSAT under the Funding Agreement dated as of June 22, 1989. On execution and delivery of this Agreement, IRBA agreed to return to the Company the full amount of the Company's debt service reserve ("Reserve Funds"), approximately $610,000 of principal and interest, relating to the bonds the Company has with IRBA and RIIFC. Such amount has been classified as debt service funds in current assets of the consolidated balance sheet. In order to avoid the loss of interest on the Reserve Funds due to early termination of certain investments, the parties agreed that the Company would render a net payment to RIPSAT in the amount of approximately $562,000. In 1997, the Company completed construction of a new headquarters and laboratory facility. In November 1997, the Company entered into sale and leaseback agreements with a real estate investment trust. Under the terms of these agreements, the Company sold its new facility for $8,000,000, incurring a $342,000 loss on the sale. The Company simultaneously entered into a fifteen-year lease for the facility. The lease agreement calls for minimum rent of $750,000 for the first five years, $937,500 for years six to ten, $1,171,900 for years eleven to fourteen and $1,465,000 in year fifteen, with a $750,000 security deposit held for the term of the lease. The Company is recognizing rent expense on a straight line basis. At December 31, 1999, the Company had incurred $426,790 in deferred rent expense. F-16 STEMCELLS, INC.

13. REDEEMABLE COMMON STOCK In November 1996, the Company signed certain collaborative development and licensing agreements with Genentech, Inc, including one under which Genentech purchased 829,171 shares of redeemable common stock for $8.3 million to fund development of products to treat Parkinson's disease. The Agreement also provided that Genentech had the right, at its discretion, to terminate the Parkinson's program at specified milestones in the program, and that if the program were terminated, Genentech had the right to require the Company to repurchase from Genentech the shares of the Company's common stock having a value equal to the amount by which the $8.3 million exceeded the expenses incurred by the Company in connection with such program by more than $1 million, based upon the share price paid by Genentech. Accordingly, the common stock is classified as redeemable common stock until such time as the related funds are expended. At December 31, 1998, $3,051,000 had been spent on the collaboration with Genentech and, accordingly, the Company has reclassified F-17 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 13. REDEEMABLE COMMON STOCK (CONTINUED) those common shares and related value to stockholders' equity. On May 21, 1998, Genentech exercised its right to terminate the collaboration and negotiations ensued with respect to the amount of redeemable common stock to be redeemed in accordance with the agreement and the method of such redemption. In March 2000, the Company reached a settlement of this matter with Genentech. Under the settlement agreement, Genentech released the Company from any obligation to redeem any shares of the Company's Common Stock held by Genentech. Accordingly, the Company reclassified the amount recorded at December 31, 1999 as Redeemable Common Stock ($5,248,000) to Stockholders' Equity in March 2000. The Company and Genentech also agreed that all of the agreements between them were terminated and that neither had any claim to the intellectual property of the other. 14. COMMON STOCK TO BE ISSUED In 1998, the Company entered into an agreement with a Company advisor, under which the advisor prepared a strategic and business overview and provided related implementation support for the Company. The advisor agreed to accept cash and the Company's common stock as partial payment for its services. In 1999, the Company issued the $187,500 of common stock due to the advisor. 15. STOCKHOLDERS' EQUITY STOCK OPTION AND EMPLOYEE STOCK PURCHASE PLANS The Company has adopted several stock plans that provide for the issuance of incentive and nonqualified stock options, performance awards and stock appreciation rights, at prices to be determined by the Board of Directors, as well as the purchase of Common Stock under an employee stock purchase plan at a discount to the market price. In the case of incentive stock options, such price will not be less than the fair market value on the date of grant. Options generally vest ratably over four years and are exercisable for ten years from the date of grant or within three months of termination. At December 31, 1999, the Company had reserved 2,603,736 shares of common stock for the exercise of stock options. The following table presents the combined activity of the Company's stock option plans (exclusive of the plans noted below) for the years ended December 31:

F-18 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 15. STOCKHOLDERS' EQUITY (CONTINUED) On July 10, 1998, the Company re-priced 751,018 outstanding stock options. No compensation expense was recorded since the re-priced options carried an exercise price equal to the market price of the Company's common stock on the date of the re-pricing. In addition to the options noted above, in conjunction with the StemCells California merger, StemCells California options originally issued under a prior StemCells California options plan were exchanged for options to purchase 250,344 shares of the Company's common stock at $.01 per share; 75,384 of these options are exercisable at December 31, 1997, 96,750 of these options vest and become exercisable only upon achievement of specified milestones, and the remaining 78,210 options vest over three years from the date of grant. The value of such options utilizing the intrinsic method, which approximated the value determined using the Black-Scholes method, was accounted for as part of the StemCells California acquisition price. Additionally, the Company adopted the 1997 CytoTherapeutics, Inc. StemCells California Research Stock Option Plan (the StemCells California Research Plan) whereby an additional 2,000,000 shares of Common Stock have been reserved. During 1997, the Company awarded options under the StemCells Research Plan to purchase 1.6 million shares of the Company's common stock to the Chief Executive Officer and scientific founders of StemCells at an exercise price of $5.25 per share. Under the original grants, approximately 100,000 of these options were exercisable immediately on the date of grant, 1,031,000 of these options would vest and become exercisable only upon achievement of specified milestones and the remaining 469,000 options would vest over eight years. Options granted to Dr. Rose, in his capacity as Chief Executive Officer, were valued using the intrinsic value method, in accordance with the provisions of APB 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES.

F-19 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 15. STOCKHOLDERS' EQUITY (CONTINUED) Pursuant to the requirements of FAS 123, the following are the pro forma net loss and net loss per share amounts for 1999, 1998, and 1997, as if the compensation cost for the option plans and the stock purchase plan had been determined based on the fair value at the grant date for grants in 1999, 1998, and 1997, consistent with the provisions of FAS 123:
1999 1998 1997 --------------------------- --------------------------- --------------------------- AS REPORTED PRO FORMA AS REPORTED PRO FORMA AS REPORTED PRO FORMA ------------ ------------ ------------ ------------ ------------ ------------ Net loss............. $(15,708,626) $(15,764,569) $(12,627,830) $(14,919,389) $(18,113,580) $(19,924,437) Net loss per share... $(.84) $(.84) $(.69) $(.82) $(1.08) $(1.19)
The weighted average fair value per share of options granted during 1999, 1998 and 1997 was $.88, $.82 and $3.40, respectively. The fair value of options and shares issued pursuant to the stock purchase plan at the date of grant were estimated using the Black-Scholes model with the following weighted average assumptions:
OPTIONS STOCK PURCHASE PLAN ------------------------------------ ------------------------------ 1999 1998 1997 1999 1998 1997 -------- -------- -------- -------- -------- -------- Expected life (years)................................. 5 5 5 5 .5 .5 Interest rate......................................... 5.5% 5.2% 6.2% 5.0% 4.64% 5.5% Volatility............................................ 96.7% 63.5% 59.0% 96.7% 63.5% 59.0%
The Company has never declared nor paid dividends on any of its capital stock and does not expect to do so in the foreseeable future. The effects on 1999, 1998 and 1997 pro forma net loss and net loss per share of expensing the estimated fair value of stock options and shares issued pursuant to the stock purchase plan are not necessarily representative of the effects on reporting the results of operations for future years as the period presented includes only four, three or two years, respectively, of option grants under the Company's plans. As required by FAS 123, the Company has used the Black-Scholes model for option valuation, which method may not accurately value the options described. STOCK WARRANTS In conjunction with the StemCells California merger, the Company exchanged StemCells California warrants for warrants to purchase 8,952 shares of Company common stock at $4.71 per share; such warrants were valued using the intrinsic value method which approximated the value determined using the Black-Scholes method and were accounted for as part of the purchase price. In conjunction with various equipment leasing agreements, the Company had outstanding warrants to purchase 31,545 shares of common stock at prices ranging from $4.00 to $9.00 per share. The warrants expired in October 2000. In connection with a public offering of common stock in April 1995, the Company issued warrants to purchase 434,500 shares of common stock at $8 per share. The warrants are nontransferable and expired in April 2000, subject to certain required exercise provisions. In addition to the foregoing rights, the holder of such warrants has the right, in the event the Company issues additional shares of common stock or other securities convertible into common stock, to purchase at the then market price F-20 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 15. STOCKHOLDERS' EQUITY (CONTINUED) of such common stock, sufficient additional shares of common stock to maintain the warrant holder's percentage ownership of the Company's common stock at 15%. This right, subject to certain conditions and limitations, expired in April 2000. COMMON STOCK RESERVED The Company has reserved 6,461,846 shares of common stock for the exercise of options, warrants and other contingent issuances of common stock. 16. RESEARCH AGREEMENTS In November 1997, StemCells California, Inc., a wholly owned subsidiary of the Company, signed a Research Funding and Option Agreement with The Scripps Research Institute ("Scripps") relating to certain stem cell research. Under the terms of the Agreement, StemCells agreed to fund research in the total amount of approximately $931,000 at Scripps over a period of three years. StemCells paid Scripps approximately $77,000 in 1997, $307,000 in 1998, and $309,000 in 1999. In addition, the Company agreed to issue to Scripps 4,837 shares of the Company's common stock and a stock option to purchase 9,674 shares of the Company's Common Stock with an exercise price of $.01 per share upon the achievement of specified milestones. Under the Agreement, StemCells has an option for an exclusive license to the inventions resulting from the sponsored research, subject to the payment of royalties and certain other amounts, and is obligated to make payments totaling $425,000 for achievement of certain milestones. In April 1997, the Company entered into an agreement with Neurospheres, Ltd., which superseded all previous licensing agreements and settled a dispute with Neurospheres. Under the terms of the settlement, the Company has an exclusive royalty bearing license for growth-factor responsive stem cells for transplantation. Neurospheres had an option to acquire co-exclusive rights but did not exercise by the April 1998 deadline. The Company retains exclusive rights for transplantation. The parties have no further research obligations to each other, and the Company is under no obligation to provide additional funding. In February 1997, the Company and Cognetix, Inc. entered into a Collaboration and Development Agreement related to the Company's former encapsulated cell technology. As part of the agreement with Cognetix, the Company purchased $250,000 of Cognetix preferred stock and, subject to certain milestones, was obligated to purchase as much as $1,500,000 of additional Cognetix stock over the next year. In July 1997, the Company loaned $250,000 to Cognetix which was repaid with interest in October 1997. In October 1998, the Company sold the $250,000 of preferred stock back to Cognetix for $298,914. The Company is under no obligation to provide funding under this agreement. In 1996, the Company signed certain collaborative development and licensing agreements with Genentech, Inc. Under the terms of one of those agreements, Genentech purchased 829,171 shares of redeemable common stock for $8.3 million to fund development of products to treat Parkinson's disease. Genentech had the right, at its discretion, to terminate the Parkinson's program at specified milestones in the program. The Agreement also provided that if the Parkinson's program were terminated and the funds the Company received from the sale of stock to Genentech pursuant to the Parkinson's agreement exceeded the expenses incurred by the Company in connection with such program by more than $1 million, Genentech had the right to require the Company to repurchase from F-21 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 16. RESEARCH AGREEMENTS (CONTINUED) Genentech shares of the Company's common stock having a value equal to the over funding, based upon the share price paid by Genentech. As such, the common stock purchased by Genentech has been classified as redeemable common stock until the funds are expended on the program. On May 21, 1998, Genentech exercised its right to terminate the collaboration and negotiations ensued with respect to the amount of redeemable common stock to be redeemed in accordance with the agreement and the method of such redemption. In March 2000 the Company announced the settlement of this matter with Genentech and at that time the redeemable common stock was reclassified to common stock. The Company is under no obligation to provide additional funding to Genentech, Inc. In March 1995, the Company signed a collaborative research and development agreement with AstraZeneca for the development and marketing of certain encapsulated-cell products to treat pain. AstraZeneca made an initial, nonrefundable payment of $5,000,000, included in revenue from collaborative agreements in 1995, a milestone payment of $3,000,000 in 1997 and was to remit up to an additional $13,000,000 subject to achievement of certain development milestones. Under the agreement, the Company was obligated to conduct certain research and development pursuant to a four-year research plan agreed upon by the parties. Over the term of the research plan, the Company originally expected to receive annual payments of $5 million to $7 million from AstraZeneca, which was to approximate the research and development costs incurred by the Company under the plan. Subject to the successful development of such products and obtaining necessary regulatory approvals, AstraZeneca was obligated to conduct all clinical trials of products arising from the collaboration and to seek approval for their sale and use. AstraZeneca had the exclusive worldwide right to market products covered by the agreement. Until the later of either the expiration of all patents included in the licensed technology or a specified fixed term, the Company was entitled to a royalty on the worldwide net sales of such products in return for the marketing license granted to AstraZeneca and the Company's obligation to manufacture and supply products. AstraZeneca had the right to terminate the original agreement beginning April 1, 1998. On June 24, 1999, AstraZeneca informed the Company of the results of AstraZeneca's analysis of the double-blind, placebo-controlled trial of the Company's encapsulated bovine cell implant for the treatment of severe, chronic pain in cancer patients. AstraZeneca determined that, based on criteria it established, the results from the 85-patient trial did not meet the minimum statistical significance for efficacy established as a basis for continuing worldwide trials for the therapy. AstraZeneca therefore indicated that it did not intend to continue the trials of the bovine cell-containing implant therapy and executed its right to terminate the agreement. The Company has no additional funding obligations with AstraZeneca. The Company has entered into other collaborative research agreements whereby the Company funds specific research programs. Pursuant to such agreements, the Company is typically granted rights to the related intellectual property or an option to obtain such rights on terms to be agreed, in exchange for research funding and specified royalties on any resulting product revenue. The Company's principal academic collaborations had been with Brown University and Dr. Aebischer and Centre Hospitalier Universitaire Vaudois in Switzerland. However, with the termination of the Company's encapsulated cell technology program and its new focus on the stem cell field, its principal academic collaborations are now with Scripps Institute and the Oregon Health Science University. Research and development expenses incurred under these collaborations amounted to approximately $868,000, $1,259,000, and $1,326,000 for the years ended December 31, 1999, 1998 and 1997, respectively. The Company has no other significant collaborative research funding obligations. F-22 STEMCELLS, INC. (FORMERLY CYTOTHERAPEUTICS, INC.) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 1999 17. INCOME TAXES Due to net losses incurred by the Company in each year since inception, no provision for income taxes has been recorded. At December 31, 1999, the Company had tax net operating loss carry forwards of $96,195,000 and research and development tax credit carry forwards of $4,035,000 which expire at various times through 2019. Due to the "change in ownership" provisions of the Tax Reform Act of 1986, the Company's utilization of its net operating loss carry forwards and tax credits may be subject to annual limitation in future periods. Significant components of the Company's deferred tax assets and liabilities are as follows:
DECEMBER 31, --------------------------- 1999 1998 ------------ ------------ Deferred tax assets: Capitalized research and development costs................ $ 4,331,000 $ 28,124,000 Net operating losses...................................... 38,478,000 10,786,000 Research and development credits.......................... 4,035,000 3,646,000 Other..................................................... 928,000 235,000 ------------ ------------ 47,772,000 42,791,000 Deferred tax liabilities: Patents...................................................

(47,526,000) (41,254,000) ------------ ------------ Net deferred tax assets..................................... $ -- $ -- ============ ============
Since there is uncertainty relating to the ultimate use of the loss carry forwards and tax credits, a valuation allowance has been recognized at December 31, 1999 and 1998, to fully offset the Company's deferred tax assets. The valuation allowance increased $6,272,000 in 1999, due primarily to the increases in net operating loss carry forwards and tax credits offset by reduction in capitalized research and development costs. 18. EMPLOYEE RETIREMENT PLAN The Company has a qualified defined contribution plan covering substantially all employees. Participants are allowed to contribute a fixed percentage of their annual compensation to the plan and the Company may match a percentage of that contribution. The Company matches 50% of employee contributions, up to 6% of employee compensation, with the Company's common stock. The related expense was $103,000, $146,000, and $169,000 for the years ended December 31, 1999, 1998 and 1997, respectively. 19. CONTINGENCIES The Company is routinely involved in arbitration, litigation and other matters as part of the ordinary course of its business. While the resolution of any matter may have an impact on the Company's financial results for a particular reporting period, management believes the ultimate F-23 STEMCELLS, INC.

CONTINGENCIES (CONTINUED) disposition of these matters will not have a materially adverse effect on the Company's consolidated financial position or results of operations. 20. SUBSEQUENT EVENTS On April 13, 2000, the Company completed arrangements to sell 1,500 shares of 6% cumulative convertible preferred stock plus a warrant for 75,000 shares of the Company's common stock to two members of its Board of Directors for $1,500,000, on terms more favorable than it was then able to obtain from outside investors.

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

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.

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.

(*)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.

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 auditedyield on U.S. Treasury debt securities. Dividend yields are based on our historical dividend payments, which have been zero to date.

The 655,967 shares (9,735,925 shares before the lastReverse Split) of such dates. The number of additional shares the Fund may be entitled to on each date will be based on the number of shares of common stock the Fund continues to hold on each date and the market price of the Company's common stock over a period prior to each date. The exercise price per share under the adjustable warrant is $0.01. Such warrants provide the Fund with the opportunity to acquire additional common shares at a nominal value if the value of the common stock that the Fund holds decreases. The Company will have the right, under certain circumstances, to cap the number of additional shares by purchasing part of the entitlement from the Fund at a purchase price based on the market price of such shares. No portion of the sale proceeds was assigned to the adjustable warrants, as the ultimate number of shares issuable upon exercise of the warrants was not determinable and the net impact on the Company's equity from any such allocation of proceeds would have been zero. The Fund also received a five-year warrant to purchase up to 101,587 shares of common stock at $4.725 per share. This warrant is callable at any time by StemCells at $7.875 per underlying share. The calculated value of this callable warrant using the Black-Scholes method is $376,888, which was treated as a credit to paid in capital stockholders' equity. The Company accounts for the sale of the stock and warrants or the exercise of warrants by adding that portion of the proceeds equal to the par value of the new shares to common stock and the balance, including the value of the warrants,rights to paid in capital. In addition, any repurchase of the shares or warrants by the Company would also be accounted for through paid in capital. In the Purchase Agreement governing the August 3, 2000 sale to the Fund, the Company granted the Fund an option to purchase up to an additional $3 million of itsacquire common stock and a callable warrant and an adjustable warrant. The Fund can exercise this option in whole or in part at any time prior to August 3, 2001. The price per share of common stock to be issued upon exercise of the option will be based on the average market price of the common stock for a five-day period prior to the date on which the option is exercised. On August 23, 2000, the Fund exercised $1,000,000 of its option to purchase additional common stock. The Fund paid $750,000 of the purchase price in connection with the closing on August 30, 2000,were cancelled and the Fund paid the remaining $250,000 upon effectiveness of a registration statement covering the shares owned by the Fund. The Fund purchased the Company's common stock at $5.53 per share, which amount was based upon the average market price of the common stock for the five-day period prior to August 23, 2000. An adjustable warrant similar to the oneCompany’s issued on August 3, 2000 was issued to the Fund on August 30, 2000, but was cancelled on November 1, 2000 by agreement of the Company and the Fund. The Fund also received a five -year warrant to purchase up to 19,900 shares of common stock at $6.03 per share. This warrant is callable by the Company at any time at $10.05 per underlying share. The calculated value of this callable warrant using the Black-Scholes method is $139,897, which the Company accounted for as a credit to paid in capital. The adjustable warrant contains provisions regarding the adjustment or replacement of the warrants in the event of stock splits, mergers, tender offers and other similar events. The adjustable F-30 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) SEPTEMBER 30, 2000 AND 1999 NOTE 7. SALE OF SECURITIES (CONTINUED) warrant also limits the number of shares that can be beneficially owned by the Fund to 9.99% of the total number of outstanding shares of Common Stock. NOTE 8. SUBSEQUENT EVENTS As previously reported, in conjunction withStock were reduced to 1,786,684 (26,518,315 before the StemCells California merger,Reverse Split).

On May 9, 2017, the Company adoptedentered into a Securities Exchange Agreement with Alpha Capital pursuant to which the 1997 CytoTherapeutics, Inc. StemCells California ResearchCompany agreed to issue 3,254 shares of the Series A Convertible Preferred Stock, Option Plan whereby an additional 2,000,000in 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, have been reserved. During 1997, the Company awarded options under this plan to purchase 1.6 million shares of the Company's common stock to the Chief Executive Officer and scientific founders of StemCells California, Inc. at an exercise price of $5.25 per share. Under the original grants, approximately 100,000 of these options were exercisable immediately on the date of the grant, 1,031,000 of these options would vest and become exercisable only upon achievement of specified milestones and the remaining 469,000 options would vest over eight years. The Company agreed on October 27, 2000 with Irving Weissman, M.D. and Fred H. Gage, Ph.D., two of the grant recipients, to amend their options. In exchange for the revision of the options, Dr. Weissman and Dr. Gage agreed to rescind their Conduct of Research Agreement with the Company, in all respects, including their right under the Agreement to reacquire certain technology under certain circumstances. Instead of vesting based on performance milestones, Dr. Weissman's and Dr. Gage's options will vest over eight years from the date of the original grant, on the same schedule as the option granted to the third founder, Dr. David Anderson. 168,750 shares vested upon the revision and the remaining 300,000 shares will vest at 50,000 shares on each September 25 until September 25, 2005, when the final 100,000 shares will vest. The exercise price for the revised options remains $5.25 per share. We expect to incur a charge of approximately $1,600,000 during the fourth quarter of 2000 relating to the vested portion of the options. The deferred compensation expense associated with the unvested portion of the grants was determined to be approximately $2.8 million. The Company plans to revalue the options using the Black-Scholes method on a quarterly basis and recognize additional compensation expense, accordingly. Under a 1997 License Agreement with NeuroSpheres, Ltd., the Company obtained an exclusive patent license in the field of transplantation. The Company entered into an additional license agreement with NeuroSpheres as of October 31, 2000, under which the Company obtained an exclusive license in the field of non-transplant uses, such as drug discovery and drug testing, so that together the licenses are exclusive for all uses of the technology. The Company made up-front payments to NeuroSpheres of 65,000 shares of its common stock and $50,000, and will make additional cash payments when milestones are achieved in the non-transplant field, or in any products employing NeuroSpheres patents for generating cells of the blood and immune system from neural stem cells. Milestone payments would total $500,000 for each product that is approved for market. On December 20, 2000, the Company announced that Donald Kennedy, Ph.D., had resigned from its board of directors. The Company reported that Dr. Kennedy resigned in connection with his becoming Editor-in-Chief of Science magazine. On that date the Company also announced that Roger M. Perlmutter had become a member of the Board. F-31 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) SEPTEMBER 30, 2000 AND 1999 NOTE 9. RECENT ACCOUNTING PRONOUNCEMENTS In June 1998, The Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Financial Instruments and for Hedging Activities" ("SFAS 133"), which provides a comprehensive and consistent standard for the recognition and measurement of derivatives and hedging activities. SFAS 133 is effective for fiscal years beginning after June 15, 2000 and is not anticipated to have an impact on results of operations or financial condition when adopted as we hold no derivative financial and instruments and do not currently engage in hedging activities. In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 ("SAB101"). SAB 101 summarizes the SEC's views in applying generally accepted accounting principles to revenue recognition. The adoption of SAB 101 had no significant impact on our revenue recognition policy or results of operations. In March 2000, the FASB issued interpretation No. 44, ("FIN44"), "Accounting for Certain Transactions Involving Stock Compensation - an Interpretation of APB 25. "This interpretation clarifies (a) the definition of employee for purposes of applying Opinion 25, (b) the criteria for determining whether a plan qualifies as a noncompensatory plan, (c) the accounting consequence of various modificationspursuant to the terms of conversion of the Series A Convertible Preferred Stock.

For the nine-month ended September 30, 2018, the holder of the Series A Convertible Preferred Stock converted 3,451 shares of the Series A Convertible Preferred Stock for 232,151 shares (3,445,266 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 previously fixed stock option or awarddefinitive 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 (d) the accounting for an exchange of stock compensation awards in a business combination. This interpretation is effective July 1, 2000, but certain conclusions in this Interpretation cover specific events that occur after either December 15, 1998, or January 12, 2000. Toto the extent that this Interpretation covers events occurring during the period after December 15, 1998, or January 12, 2000, but before the effective datesuch shareholders are unable to sell enough of July 1, 2000, the effectstheir shares to cover certain of applying this interpretation are recognized on a prospective basis from July 1, 2000. The adoption of FIN 44 does not have a material impact on our financial statements. F-32 PRO FORMA FINANCIAL INFORMATION During the third quarter of 1999, management reached a decision to exit the Company's Encapsulated Cell Therapy (ECT) activities, dispose of the related intellectual property, facilities and equipment and relocate the Lincoln, RI corporate headquarters to Sunnyvale, CA. The Company terminated legal, professional and consulting contractual arrangements in support of ECT research. The Company had used these legal, professional and consulting contractual arrangements to meet regulatory requirements in support of its research work, to support contractual arrangements with clinical sites, to provide assistance at clinical sites in administrating therapy and documenting activities, and to assist in compliance with FDA and other regulations regarding its clinical trials. ECT related patent law work was also terminated. The Company also engaged professional consultants in connection with the determination to exit its ECT activities and restructure its operations, which concluded with the exit from ECT activities and relocation of its corporate headquarters to California. The Company reduced its workforce by approximately 58 employees who had been focused on ECT programs and 10 administrative employees. At the same time, the Company accrued various estimated expenses associated with the exit and wind-down of the ECT activities, disposal of the related property and relocation of the corporate headquarters. Additional accruals were provided in December 1999 for expenses relating to settlement of a 1989 funding arrangement with the Rhode Island Partnership for Science and Technologytheir Israeli tax liabilities resulting from the Company's move outMerger. Such repurchase(s), if any, would occur only after the two-year anniversary of Rhode Island, further adjustmentthe 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 carrying values and estimated carrying costs associated with the Rhode Island facilities through the expected disposition date. In addition, during December 1999,to the Company liquidated certain ECT equipment and sold its ECT intellectual property to Neurotech, S.A. for $3,000,000. The tabular unaudited pro forma consolidated statement of operations presentsas (a) the effectssettlement requires acquiring the shares at a discount on the fair market value of the sale, wind-downshare at the time of repurchase and relocation, as if they had occurred at January 1, 1999.
