Preliminary Prospectus

InVivo Therapeutics Holdings Corp.

Shares of Common Stock and
Warrants to Purchase Shares of Common Stock
and
Pre-funded Warrants to Purchase Shares of Common Stock and
Warrants to Purchase Shares of Common Stock

We are offering shares of common stock, together with warrants (the 'Series A warrants') to purchase shares of common stock at an assumed combined public offering price of $ per share and Series A warrant, which is equal to the last reported sale price per share of our common stock on the Nasdaq Capital Market on , 2020, (and the shares issuable from time to time upon exercise of the Series A warrants) pursuant to this prospectus. The shares of common stock and Series A warrant will be separately issued, but the shares of common stock and Series A warrants will be issued to purchasers in the ratio of one to one. Each Series A warrant will have an exercise price of $ per share, will be exercisable upon issuance and will expire years from the date of issuance.

We are also offering pre-funded warrants (the 'Series B pre-funded warrants' and collectively with the Series A warrants, the 'warrants') to those purchasers, whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering in lieu of the shares of our common stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Series B pre-funded warrant will be exercisable for one share of common stock at an exercise price of $0.01 per share. Each Series B pre-funded warrant is being issued together with the same Series A warrant described above being issued with each share common stock. The assumed combined public offering price for each such Series B pre-funded warrant, together with the Series A warrant, is $ , which is equal to the last reported sale price of our common stock on the Nasdaq Capital Market on , 2020 less the $0.01 per share exercise price of each such Series B pre-funded warrant. Each Series B pre-funded warrant will be exercisable upon issuance and will expire years from the date of issuance. The Series B pre-funded warrants and Series A warrants are immediately separable and will be issued separately in this offering.

There is no established public trading market for the warrants, and we do not expect a market to develop. We do not intend to apply for listing of the warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the warrants will be limited.

We have engaged H.C. Wainwright & Co., LLC, or the placement agent, to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number of securities or dollar amount. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum offering requirement. We will bear all costs associated with the offering. See 'Plan of Distribution' on page 37 of this prospectus for more information regarding these arrangements.

Our common stock is listed on the Nasdaq Capital Market under the symbol 'NVIV.' On February 20, 2020, the last reported sale price of our common stock on the Nasdaq Capital Market was $7.07 per share. All share, Series A warrant, and Series B pre-funded warrant numbers are based on an assumed combined public offering price of $ per share or Series B pre-funded warrant, as applicable, and Series A warrant.

The combined public offering price per share and Series A warrant and the combined public offering price per Series B pre-funded warrant and Series A warrant will be determined between us and investors based on market conditions at the time of pricing, and may be at a discount to the current market price of our common stock. Therefore, the recent market price used throughout this prospectus may not be indicative of the actual public offering price.

Business Overview

Overview

We are a research and clinical-stage biomaterials and biotechnology company with a focus on treatment of spinal cord injuries, or SCIs. Our mission is to redefine the life of the SCI patient, and we seek to develop treatment options intended to provide meaningful improvement in patient outcomes following SCI. Our approach to treating acute SCIs is based on our investigational Neuro-Spinal Scaffold implant, a bioresorbable polymer scaffold that is designed for implantation at the site of injury within a spinal cord and is intended to treat acute SCI. The Neuro-Spinal Scaffold implant incorporates intellectual property licensed under an exclusive, worldwide license from Boston Children's Hospital, or BCH, and the Massachusetts Institute of Technology, or MIT. We also plan to evaluate other technologies and therapeutics that may be complementary to our development of the Neuro-Spinal Scaffold implant or offer the potential to bring us closer to our goal of redefining the life of the SCI patient.

The current standard of care for acute management of spinal cord injuries focuses on preventing further injury to the spinal cord. However, the current standard of care does not address repair of the spinal cord.

For additional information regarding our business, see the section entitled 'Business' included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, as well as the sections entitled 'Management's Discussion and Analysis of Financial Condition and Results of Operations' and our financial statements and the related notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, each of which is incorporated by reference into this prospectus.

Our Clinical Program

We currently have one clinical development program for the treatment of acute SCI.

Neuro-Spinal Scaffold Implant for acute SCI

Our Neuro-Spinal Scaffold implant is an investigational bioresorbable polymer scaffold that is designed for implantation at the site of injury within a spinal cord. The Neuro-Spinal Scaffold implant is intended to promote appositional, or side-by-side, healing by supporting the surrounding tissue after injury, minimizing expansion of areas of necrosis, and providing a biomaterial substrate for the body's own healing/repair processes following injury. We believe this form of appositional healing may spare white matter, increase neural sprouting, and diminish post-traumatic cyst formation.

Table of Contents

The Neuro-Spinal Scaffold implant is composed of two biocompatible and bioresorbable polymers that are cast to form a highly porous investigational product:

• Poly lactic-co-glycolic acid, a polymer that is widely used in resorbable sutures and provides the biocompatible support for Neuro-Spinal Scaffold implant; and

• Poly-L-Lysine, a positively charged polymer commonly used to coat surfaces in order to promote cellular attachment.

Because of the complexity of SCIs, it is likely that multi-modal therapies will be required to maximize positive outcomes in SCI patients. In the future, we may attempt to further enhance the performance of our Neuro-Spinal Scaffold implant through multiple combination strategies involving electrostimulation devices, additional biomaterials, drugs approved by the U.S. Food and Drug Administration, or FDA, or growth factors. We expect the Neuro-Spinal Scaffold implant to be regulated by the FDA as a Class III medical device.

Completed Pilot Study

We conducted an early feasibility human pilot study, as the initial phase of a larger pivotal study, of our Neuro-Spinal Scaffold under our approved Investigational Device Exemption, or IDE, application for the treatment of complete, traumatic acute SCI. The study was intended to assess the safety and feasibility of the Neuro-Spinal Scaffold for the treatment of complete thoracic functional SCI, as well as to gather preliminary evidence of the clinical effectiveness of the Neuro-Spinal Scaffold.

The pilot study was initially approved for five subjects in up to six clinical sites across the United States, and was later modified to increase the number of allowable clinical sites to up to 20 and to permit enrollment of up to 10 subjects. The pilot study was initially staggered such that each patient that met the eligibility criteria would be followed for three months prior to enrolling the next patient in the study. In December 2014, the FDA approved an expedited enrollment plan that allowed us to continue enrolling patients more rapidly barring any significant safety issues. We enrolled five subjects in the pilot study between October 2014 and September 2015. The FDA approved conversion of this pilot study to a pivotal probable benefit study, which we refer to as The INSPIRE Study, that includes data from the patients enrolled in the pilot study.

The INSPIRE Study

Our Neuro-Spinal Scaffold implant has been studied in The INSPIRE Study: the 'InVivo Study of Probable Benefit of the Neuro-Spinal Scaffold for Safety and Neurologic Recovery in Subjects with Complete Thoracic AIS A Spinal Cord Injury,' under an Investigational Device Exemption, or IDE, application for the treatment of neurologically complete thoracic traumatic acute SCI. We commenced an FDA-approved pilot study in 2014 that the FDA approved converting into The INSPIRE Study in January 2016. As of December 31, 2017, we had implanted our Neuro-Spinal Scaffold implant in a total of 19 patients in The INSPIRE Study, 16 of whom reached the six-month primary endpoint visit, and three of whom died. In July 2017, after the third patient death, enrollment of patients in The INSPIRE Study was placed on hold as we engaged with the FDA to address the patient deaths. We subsequently closed enrollment in The INSPIRE Study and will follow the remaining active subjects until completion. Following discussions with the FDA, in March 2018, we received FDA approval for a randomized controlled trial to supplement the existing clinical evidence for the Neuro-Spinal Scaffold implant that we obtained from The INSPIRE Study. We refer to this as the INSPIRE 2.0 Study.

The purpose of The INSPIRE Study, which was the original study, was to evaluate whether the Neuro-Spinal Scaffold implant is safe and demonstrates probable benefit for the treatment of complete T2-T12 neurological level of injury, or (NLI), SCI. The primary endpoint was defined as the proportion of patients achieving an improvement of at least 1 AIS grade at six months post-implantation.

Table of Contents

Additional endpoints included measurements of pain, sensory and motor scores, bladder and bowel function, Spinal Cord Independence Measure (a disability scale for patients with SCI), and quality of life. The INSPIRE Study included an Objective Performance Criterion, or OPC, which is a measure of study success used in clinical studies designed to demonstrate safety and probable benefit in support of a Humanitarian Device Exemption, or HDE, approval. At the time enrollment of patients in The INSPIRE Study was placed on hold, the OPC was defined as 25% or more of the patients in the study demonstrating an improvement of at least 1 AIS grade at the six-month post-implantation visit.

The FDA approved the enrollment of up to 30 patients in The INSPIRE Study so that there would be at least 20 evaluable patients at the primary endpoint analysis, accounting for events such as screen failures or deaths that would prevent a patient from reaching the primary endpoint visit. Of the 19 patients implanted in The INSPIRE Study, 16 patients have reached the six-month primary endpoint visit. Of these 16, seven had improved from complete AIS A SCI to incomplete SCI (two patients to AIS C and five patients to AIS B) at the six-month primary endpoint visit and nine had not demonstrated improvement at that visit. Three of the seven patients who improved were assessed to have AIS B SCI at the six-month primary endpoint and were later assessed to have improved to AIS C SCI at the 12 or 24-month visits. Two of the 16 patients were initially assessed to have improved from complete AIS A SCI to incomplete AIS B SCI, but each was later assessed to have reverted to complete AIS A SCI prior to the six-month examination. One of these two was then assessed at the six month visit to have improved again to AIS B and the other remained AIS A. Since we have closed enrollment, the target of enrolling 20 evaluable patients into The INSPIRE Study will not be reached.

The FDA had previously recommended that we include a randomized, concurrent control arm in The INSPIRE Study. Acting on the FDA's recommendation, we proposed and received approval for the INSPIRE 2.0 Study (described below) to supplement the existing clinical evidence for the Neuro-Spinal Scaffold implant. In addition, as 1 source of comparator data, we completed the Contemporary Thoracic SCI Registry Study, or the CONTEMPO Registry Study. The CONTEMPO Registry Study utilized existing databases and registries to develop a historical comparator that, to the extent possible, matched patients to those patients enrolled in The INSPIRE Study. The CONTEMPO Registry Study was designed to provide comprehensive natural history benchmarks for The INSPIRE Study results that included SCI patients with similar baseline characteristics treated since 2006. The CONTEMPO Registry Study included data from the Christopher & Dana Reeve Foundation North American Clinical Trials Network Registry, or NACTN, as well as the Model Systems Registry and the European Multicenter Study about Spinal Cord Injury, or EMSCI. We announced top-line findings from CONTEMPO in March 2018 from a total of 170 patients from the 3 registries consisting of: 12 individuals from NACTN, 64 from EMSCI, and 94 from the Model Systems Registry. AIS conversion rates at approximately 6 months post-injury varied from 16.7% - 23.4% across the 3 registries. In 2 of the registries, there was a skew of the patient population to low (T10- T12) thoracic injuries, representing 46-47% of the registry population. This compares to just 4 out of 16 patients (25%) in follow-up in the INSPIRE study with low thoracic injuries. Patients with low thoracic injuries are known to have the best prognoses, and the conversion rates were the highest in the low thoracic group in all 3 registries and the INSPIRE study. When all 3 registries were normalized to the INSPIRE patient population distribution across T2-T5, T6-T9 and T10-T12 injury groups, the normalized conversion rate for CONTEMPO registries ranged from 15.5%-20.6%. We cannot be certain what additional information or studies will be required by the FDA to approve our HDE submission.

INSPIRE 2.0 Study

Our Neuro-Spinal Scaffold implant has been approved to be studied under our approved IDE in the INPSIRE 2.0 Study, which is titled the 'Randomized, Controlled, Single-blind Study of Probable Benefit of the Neuro-Spinal Scaffold™ for Safety and Neurologic Recovery in Subjects with Complete Thoracic AIS A Spinal Cord Injury as Compared to Standard of Care.' The purpose of the INSPIRE

6

Table of Contents

2.0 Study is to assess the overall safety and probable benefit of the Neuro-Spinal Scaffold for the treatment of neurologically complete thoracic traumatic acute SCI. The INSPIRE 2.0 Study is designed to enroll 10 subjects into each of the two study arms, which we refer to as the Scaffold Arm and the Comparator Arm. Patients in the Comparator Arm will receive the standard of care, which is spinal stabilization without dural opening or myelotomy. The INSPIRE 2.0 Study is a single blind study, meaning that the patients and assessors are blinded to treatment assignments. The FDA approved the enrollment of up to 35 patients in this study so that there would be at least 20 evaluable patients (10 in each study arm) at the primary endpoint analysis, accounting for events such as screen failures or deaths that would prevent a patient from reaching the primary endpoint visit. We expect to conduct the INSPIRE 2.0 Study at up to 25 sites in the United States. Enrolling patients in the INSPIRE 2.0 Study requires the approvals of the institutional review boards, or IRBs, at each clinical site. As of February 14, 2020, the first five patients in the INSPIRE 2.0 Study have been enrolled and 15 sites are open. Given the number of clinical sites that will be open for enrollment during 2020, we estimate that enrollment in the INSPIRE 2.0 Study will be complete in the fourth quarter of 2020, with the final patient enrolled in the INSPIRE 2.0 study reaching their six-month primary endpoint visit in the second quarter of 2021.

The primary endpoint is defined as the proportion of patients achieving an improvement of at least one AIS grade at six months post-implantation. Assessments of AIS grade are at hospital discharge, three months, six months, 12 months and 24 months. The definition of study success for INSPIRE 2.0 is that the difference in the proportion of subjects who demonstrate an improvement of at least one grade on AIS assessment at the six-month primary endpoint follow-up visit between the Scaffold Arm and the Comparator Arm must be equal to or greater than 20%. In one example, if 50% of subjects in the Scaffold Arm have an improvement of AIS grade at the six-month primary endpoint and 30% of subjects in the Comparator Arm have an improvement, then the difference in the proportion of subjects who demonstrated an improvement is equal to 20% (50% minus 30% equals 20%) and the definition of study success would be met. In another example, if 40% of subjects in the Scaffold Arm have an improvement of AIS grade at the six-month primary endpoint and 30% of subjects in the Comparator Arm have an improvement, then the difference in the proportion of subjects who demonstrated an improvement is equal to 10% (40% minus 30% equals 10%) and the definition of study success would not be met. Additional endpoints include measurements of changes in NLI, sensory levels and motor scores, bladder, bowel and sexual function, pain, Spinal Cord Independence Measure, and quality of life.

Although The INSPIRE Study is structured with the OPC as the primary component for demonstrating probable benefit, the OPC is not the only variable that the FDA would evaluate when reviewing a future HDE application. Similarly, while our INSPIRE 2.0 Study is structured with a definition of study success requiring a minimum difference between study arms in the proportion of subjects achieving improvement, that success definition is not the only factor that the FDA would evaluate in the future HDE application. Approval is not guaranteed if the OPC is met for The INSPIRE Study or the definition of study success is met for the INSPIRE 2.0 Study, and even if the OPC or definition of study success are not met, the FDA may approve a medical device if probable benefit is supported by a comprehensive review of all clinical endpoints and preclinical results, as demonstrated by the sponsor's body of evidence.

In 2016, the FDA accepted our proposed HDE modular shell submission and review process for the Neuro-Spinal Scaffold implant. The HDE modular shell is comprised of three modules: a preclinical studies module, a manufacturing module, and a clinical data module. As part of its review process, the FDA reviews each module, which are individual sections of the HDE submission, on a rolling basis. Following the submission of each module, the FDA reviews and provides feedback, typically within 90 days, allowing the applicant to receive feedback and potentially resolve any deficiencies during the review process. Upon receipt of all three modules, which constitutes the complete HDE submission, the

Table of Contents

FDA makes a filing decision that may trigger the review clock for an approval decision. We submitted the first module in March 2017 and received feedback in June 2017. We submitted an updated first module in the fourth quarter of 2019. The HDE submission will not be complete until the manufacturing and clinical modules are also submitted.

Recent Developments

On January 21, 2020, we amended our articles of incorporation to increase the number of authorized shares of our common stock from 25,000,000 to 500,000,000 shares of common stock, without giving effect to the 1-for-30 reverse stock split we effected on February 11, 2020 (the '2020 Reverse Split'). All share and per share numbers included in this prospectus give effect to the 2020 Reverse Split.

THE OFFERING

Securities offered by us in this offering: shares of our common stock and Series A warrants to purchase shares of common stock, or Series B pre-funded warrants to purchase shares of common stock and Series A warrants to purchase shares of common stock.
Description of Series A warrants: The shares, or Series B pre-funded warrants, and Series A warrants will be separately transferable immediately upon issuance, but the shares, or Series B pre-funded warrants, and Series A warrants will be issued to purchasers in the ratio of one to one. Each Series A warrant will have an exercise price of $ per share, will be exercisable upon issuance and will expire years from the date of issuance.
Description of Series B pre-funded warrants: If the issuance of shares of our common stock to a purchaser in this offering would result in such purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering, then such purchaser may purchase, if they so choose, in lieu of the shares of our common stock that would result in such excess ownership, a Series B pre-funded warrant to purchase shares of our common stock for a purchase price per share of common stock subject to such Series B pre-funded warrant equal to the per share public offering price for the common stock in this offering less $0.01. Each Series B pre-funded warrant will have an exercise price of $0.01 per share, will be exercisable upon issuance and will expire years from the date of issuance. Purchasers of Series B pre-funded warrants will also receive Series A warrants as if such purchasers were buying shares of our common stock in this offering. This prospectus also relates to the offering of the shares of common stock issuable upon exercise of these Series B pre-funded warrants.
Common stock outstanding after this offering shares of common stock, assuming no sale of Series B pre-funded warrants in this offering and no exercise of the Series A warrants being issued in this offering.
Use of proceeds We intend to use the net proceeds from this offering for working capital, business development activities, and general corporate purposes. See 'Use of Proceeds' on page 17 of this prospectus.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the risks and uncertainties described below and in the section entitled 'Risk Factors' included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, which is incorporated herein by reference, and other filings we make with the Securities and Exchange Commission, or SEC, from time to time, which are incorporated by reference herein in their entirety, together with the other information in this prospectus and the information incorporated by reference herein and in any free writing prospectus that we may authorize for use in connection with this offering. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could suffer materially. In such event, the trading price of our common stock could decline and you might lose all or part of your investment.

Risks Related to This Offering

We have broad discretion over the use of our cash and cash equivalents, including the net proceeds we receive in this offering, and may not use them effectively.

Our management has broad discretion to use our cash and cash equivalents, including the net proceeds we receive in this offering, to fund our operations and could spend these funds in ways that do not improve our results of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our product candidates. Pending their use to fund operations, we may invest our cash and cash equivalents in a manner that does not produce income or that loses value.

Even if this offering is successful, we may need additional funding to continue our operations. If we are unable to raise capital when needed, we could be forced to delay, reduce, or eliminate our product development programs or commercialization efforts, engage in one or more potential transactions, or cease our operations entirely.

Even if this offering is successful, we may need to secure additional resources to support our continued operations, and to complete clinical development of our Neuro-Spinal Scaffold, including resources needed to complete enrollment in our INSPIRE 2.0 Study or to reach submission of the HDE application to the FDA, plus resources for engaging in potential business development activities. In addition, we expect that our expenses will increase in connection with our ongoing activities, particularly as we conduct our INSPIRE 2.0 Study, and as we seek regulatory approval for our Neuro-Spinal Scaffold implant. If we obtain regulatory approval for any of our current or future product candidates, we expect to incur significant commercialization expenses related to manufacturing, marketing, sales, and distribution. Accordingly, we may need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise additional capital, we may seek to engage in one or more potential transactions, such as the sale of our company, a strategic partnership with one or more parties or the licensing, sale or divestiture of some of our assets or proprietary technologies, or we may be forced to cease our operation entirely. There can be no assurance that we will be able to enter into such a transaction or transactions on a timely basis or on terms that are favorable to us. If we are unable to raise capital when needed or on attractive terms, or should we engage in one or more potential strategic transactions, we could be forced to delay, reduce, or eliminate our research and development programs or any future commercialization efforts. If we determine to change our business strategy or to seek to engage in a strategic transaction, our future business, prospects, financial position and operating results could be significantly different than those in historical periods or projected by our management. Because of the significant uncertainty regarding these events, we are not able to accurately predict the impact of any potential changes in our existing business strategy.

Table of Contents

Our future funding requirements, both near- and long-term, will depend on many factors, including, but not limited to:

• the scope, progress, results, and costs of preclinical development, laboratory testing, and clinical trials for our Neuro-Spinal Scaffold implant and any other product candidates that we may develop or acquire, including our INSPIRE 2.0 Study;

• future clinical trial results of our Neuro-Spinal Scaffold implant;

• the timing of, and the costs involved in, obtaining regulatory approvals for the Neuro-Spinal Scaffold implant, and the outcome of regulatory review of the Neuro-Spinal Scaffold implant;

• the cost and timing of future commercialization activities for our products if any of our product candidates are approved for marketing, including product manufacturing, marketing, sales, and distribution costs;

• the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

• the cost of having our product candidates manufactured for clinical trials in preparation for regulatory approval and in preparation for commercialization;

• the cost and delays in product development as a result of any changes in regulatory oversight applicable to our product candidates;

• our ability to establish and maintain strategic collaborations, licensing, or other arrangements and the financial terms of such agreements;

• the cost and timing of establishing sales, marketing, and distribution capabilities;

• the costs involved in preparing, filing, prosecuting, maintaining, defending, and enforcing our intellectual property portfolio;

• the efforts and activities of competitors and potential competitors;

• the effect of competing technological and market developments; and

• the extent to which we acquire or invest in businesses, products, and technologies.

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive, and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for several years, if at all. Accordingly, we may need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all and if we are not successful in raising additional capital, we may not be able to continue as a going concern.

There is substantial doubt about our ability to continue as a going concern, which will affect our ability to obtain future financing and may require us to curtail our operations.

Our consolidated financial statements as of December 31, 2019 were prepared under the assumption that we will continue as a going concern. At December 31, 2019, we had cash and cash equivalents of $6.6 million. We estimate that our existing cash resources, together with the anticipated proceeds of this offering, will be sufficient to fund our operations into the second quarter of 2021. This estimate is based on assumptions that may prove to be wrong; expenses could prove to be significantly higher, leading to a more rapid consumption of our existing resources.

12

Table of Contents

Our ability to continue as a going concern will depend on our ability to obtain additional equity or debt financing, attain further operating efficiencies, reduce or contain expenditures, and, ultimately, to generate revenue.

Our independent registered public accounting firm expressed substantial doubt as to our ability to continue as a going concern in its report dated February 20, 2020 included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, which we filed with the SEC on February 20, 2020. Our management has determined that there continues to be substantial doubt regarding our ability to continue as a going concern. Even if this offering is successful, we expect that there will continue to be substantial doubt about our ability to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited consolidated financial statements, and it is likely that investors will lose all or part of their investment. If we seek additional financing to fund our business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding to us on commercially reasonable terms or at all.

You may experience immediate and substantial dilution.

Because the assumed price per share of common stock and related warrants being issued may be substantially higher than the net tangible book value per share of our common stock, you may experience substantial dilution to the extent of the difference between the assumed offering price per share of common stock you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Our net tangible book value as of December 31, 2019 was approximately $5.6 million, or $10.09 per share of common stock. Net tangible book value per share is equal to our total tangible assets minus total liabilities, all divided by the number of shares of common stock outstanding. See the section entitled 'Dilution' on page 21 below for a more detailed illustration of the dilution you may incur if you participate in this offering.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the public offering price for the securities in this offering. We may sell shares or other securities in any other offering at prices that are less than the price paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders.

In the foreseeable future, we do not intend to pay cash dividends on shares of our common stock so any investor gains will be limited to the value of our shares.

We currently anticipate that we will retain future earnings for the development, operation, and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any gains to stockholders will therefore be limited to the increase, if any, in our share price.

There is no public market for the Series A warrants or the Series B pre-funded warrants being issued by us in this offering.

There is no established public trading market for the Series A warrants or the Series B pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply to list the Series A warrants or the Series B pre-funded warrants on any national securities exchange or other

13

Table of Contents

nationally recognized trading system, including the Nasdaq Capital Market. Without an active market, the liquidity of the Series A warrants and the Series B pre-funded warrants will be limited.

Holders of Series B pre-funded warrants or Series A warrants purchased in this offering will have no rights as common stockholders until such holders exercise their Series B pre-funded warrants or Series A warrants and acquire our common stock, except as otherwise provided in the Series B pre-funded warrants.

Until holders of Series B pre-funded warrants or Series A warrants acquire shares of our common stock upon exercise thereof, such holders will have no rights with respect to the shares of our common stock underlying the Series B pre-funded warrants and Series A warrants, except to the extent that holders of the Series B pre-funded warrants will have certain rights to participate in distributions or dividends paid on our common stock as set forth in the Series B pre-funded warrants. Upon exercise of the Series B pre-funded warrants or Series A 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.

The Series A warrants are speculative in nature.

The Series A warrants do not confer any rights of common stock ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of common stock at a fixed price for a limited period of time. Specifically, commencing on the date of issuance, holders of the Series A warrants may exercise their right to acquire the common stock and pay an exercise price of $ per share of common stock, subject to certain adjustments, prior to years from the date of issuance in the case of the Series A warrants, after which date any unexercised Series A warrants will expire and have no further value. Moreover, following this offering, the market value of the Series A warrants, if any, is uncertain and there can be no assurance that the market value of the Series A warrants will equal or exceed their imputed offering price. The Series A warrants will not be listed or quoted for trading on any market or exchange. There can be no assurance that the market price of the common stock will ever equal or exceed the exercise price of the Series A warrants, and consequently, it may not ever be profitable for holders of the Series A warrants to exercise such warrants.

This is a best efforts offering, no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth above. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations and to complete clinical development of our Neuro-Spinal Scaffold, including resources needed to complete enrollment in our INSPIRE 2.0 Study or to reach submission of the HDE application to the FDA. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds, which may not be available or available on terms acceptable to us.

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $ million based on the sale of shares of common stock and Series A warrants to purchase shares of common stock at an assumed combined public offering price of $ per share of common stock and Series A warrant, which is equal to the last reported sale price per share of our common stock on the Nasdaq Capital Market on , 2020, after deducting the placement agent fees and estimated offering expenses payable by us, and assuming no sale of Series B pre-funded warrants in this offering and no exercise of the Series A warrants being issued in this offering. However, because this is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, the placement agent's fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus.

These estimates exclude the proceeds, if any, from the exercise of Series A warrants issued in this offering. If all of the Series A warrants issued in this offering were to be exercised in cash at an assumed exercise price of $ per share of common stock, we would receive additional proceeds of approximately $ million. We cannot predict when or if these Series A warrants will be exercised. It is possible that these Series A warrants may expire and may never be exercised. Additionally, the Series A warrants contain a cashless exercise provision that permit exercise of Series A warrants on a cashless basis at any time where there is no effective registration statement under the Securities Act of 1933, as amended, covering the issuance of the underlying shares.

We intend to use the net proceeds from this offering for working capital, business development activities, and general corporate purposes. We cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering. Accordingly, our management will have broad discretion and flexibility in applying the net proceeds from the sale of securities issued pursuant to this prospectus. Even if this offering is successful, we may need to secure additional resources to support our continued operations, and to complete clinical development of our Neuro-Spinal Scaffold, including resources needed to complete enrollment in our INSPIRE 2.0 Study or to reach submission of the HDE application to the FDA, plus resources for engaging in potential business development activities. Pending the uses described above, we intend to invest the net proceeds from this offering in a variety of capital preservation investments, including short-term, investment-grade and interest-bearing instruments.

DIVIDEND POLICY

We do not intend to pay cash dividends on our common stock for the foreseeable future, but currently intend to retain any future earnings to fund the development and growth of our business. The payment of cash dividends, if any, on our common stock, will rest solely within the discretion of our board of directors and will depend, among other things, upon our earnings, capital requirements, financial condition, and other relevant factors.

DILUTION

If you invest in our securities, your interest will be diluted to the extent of the difference between the combined price per share and warrant you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Our net tangible book value as of December 31, 2019 was approximately $5.6 million, or $10.09 per share of common stock. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of December 31, 2019. Dilution with respect to net tangible book value per share represents the difference between the amount per combined share and warrant paid by purchasers of shares of common stock and warrants in this offering and the net tangible book value per share of our common stock immediately after this offering. All share and per share numbers included in this section, and elsewhere in this prospectus, give effect to the 2020 Reverse Split.

After giving effect to the assumed sale of shares of common stock and Series A warrants to purchase shares of common stock in this offering at an assumed combined public offering price of $ per share of common stock and Series A warrant, which is equal to the last reported sale price of our common stock on the Nasdaq Capital Market on , 2020 after deducting the placement agent fees and estimated offering expenses payable by us and assuming no sale of Series B pre-funded warrants in this offering and no exercise of the Series A warrants being issued in this offering, our as adjusted net tangible book value as of December 31, 2019 would have been approximately $ million, or $ per share. This represents an immediate increase in net tangible book value of $ per share to existing stockholders and immediate dilution of $ per share to investors purchasing our securities in this offering at the assumed combined public offering price. The following table illustrates this dilution on a per share basis:

Assumed combined public offering price per share of common stock and Series A warrant $
Net tangible book value per share as of December 31, 2019 $ 10.09
Increase in net tangible book value per share attributable to this offering $
As adjusted net tangible book value per share as of December 31, 2019, after giving effect to this offering $
Dilution per share to new investors in this offering $

The dilution information set forth in the table above is illustrative only and will be adjusted based on the actual combined public offering price and other terms of this offering determined at pricing. In addition, if previously issued options and warrants to acquire common stock are exercised at prices below the combined offering price or the warrants are accounted for as liabilities, you will experience further dilution.

A $ increase or decrease in the assumed combined public offering price of $ per share of common stock and Series A warrant, which is equal to the last reported sale price of our common stock on the Nasdaq Capital Market on , 2020, would increase or decrease our adjusted net tangible book value after this offering by approximately $ million, and decrease or increase dilution per share to new investors by approximately $ , after deducting the placement agent fees and estimated offering expenses payable by us and assuming no sale of Series B pre-funded warrants in this offering and no exercise of the Series A warrants being issued in this offering.

We may also increase or decrease the number of shares of common stock and Series A warrants we are offering. An increase of in the number of shares of common stock and Series A warrants offered by us would increase our adjusted net tangible book value per share after this offering

by approximately $ million, and increase dilution per share to new investors by approximately $ , after deducting the placement agent fees and estimated offering expenses payable by us and assuming no sale of Series B pre-funded warrants in this offering and no exercise of the Series A warrants being issued in this offering. A decrease of in the number of shares of common stock and Series A warrants offered by us would decrease our adjusted net tangible book value per share after this offering by approximately $ million, and decrease or increase dilution per share to new investors by approximately $ , after deducting the placement agent fees and estimated offering expenses payable by us and assuming no sale of Series B pre-funded warrants in this offering and no exercise of the Series A warrants being issued in this offering. The information discussed above is illustrative only and will adjust based on the actual offering price, the actual number of shares and Series A warrants we offer in this offering, and other terms of this offering determined at pricing.

The information above is based on 550,736 shares of our common stock outstanding as of December 31, 2019, and excludes:

• 270,940 shares of common stock issuable upon the exercise of warrants outstanding as of December 31, 2019 at a weighted average exercise price of $86.09 per share;

• 4,187 shares of common stock issuable upon the exercise of options at a weighted average exercise price of $1,077.78 per share and 200 shares of common stock issuable upon vesting of restricted stock units outstanding as of December 31, 2019 pursuant to our stock incentives plans (collectively, the 'Incentive Plans');

• 205 shares of common stock available for future issuance under the Incentive Plans and our 401(k) plan as of December 31, 2019; and

• 264 shares of common stock reserved for future sale under our employee stock purchase plan as of December 31, 2019.

DESCRIPTION OF OUR CAPITAL STOCK

General

The following description of our capital stock is intended as a summary only and therefore is not a complete description of our capital stock. This description is based upon, and is qualified by reference to, applicable provisions of the Nevada Revised Statutes (the 'NRS'), our articles of incorporation, as amended, and our amended and restated bylaws and, which are filed as exhibits to the registration statement of which this prospectus forms a part.

Authorized Capital Stock

After giving effect to the 2020 Reverse Split, our authorized capital stock consists of 16,666,667 shares of common stock, par value $0.00001 per share. As of December 31, 2019, 550,736 shares of common stock were outstanding. Our common stock is registered under Section 12(b) of the Exchange Act.

Common Stock

Voting Rights. The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of the stockholders, including the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all shares of common stock that are present in person or represented by proxy. Except as otherwise provided by law, amendments to our articles of incorporation generally must be approved by a majority of the votes entitled to be cast by all outstanding shares of common stock. Our articles of incorporation do not provide for cumulative voting in the election of directors.

Dividends. Except as provided by law or in our articles of incorporation, the holders of common stock will be entitled to such cash dividends as may be declared from time to time by our board of directors from funds available.

Liquidation, Dissolution and Winding Up. Upon liquidation, dissolution or winding up of our Company, the holders of common stock will be entitled to receive pro rata all assets available for distribution to such holders after payment of our liabilities.

Other Rights. The holders of common stock have no preferential or preemptive right and no subscription, redemption or conversion privileges with respect to the issuance of additional shares of our common stock.

Provisions of Our Articles of Incorporation and Bylaws and the NRS That May Have Anti-Takeover Effects

Anti-Takeover Effects of Provisions of Nevada State Law

We may be or in the future we may become subject to Nevada's control share laws. A corporation is subject to Nevada's control share law if it has more than 200 stockholders, at least 100 of whom are stockholders of record and residents of Nevada, and if the corporation does business in Nevada, including through an affiliated corporation. This control share law may have the effect of discouraging corporate takeovers. We currently have less than 100 stockholders of record who are residents of Nevada.

The control share law focuses on the acquisition of a 'controlling interest,' which means the ownership of outstanding voting shares that would be sufficient, but for the operation of the control share law, to enable the acquiring person to exercise the following proportions of the voting power of

23

Table of Contents

the corporation in the election of directors: (1) one-fifth or more but less than one-third; (2) one-third or more but less than a majority; or (3) a majority or more. The ability to exercise this voting power may be direct or indirect, as well as individual or in association with others.

The effect of the control share law is that an acquiring person, and those acting in association with that person, will obtain only such voting rights in the control shares as are conferred by a resolution of the stockholders of the corporation, approved at a special or annual meeting of stockholders. The control share law contemplates that voting rights will be considered only once by the other stockholders. Thus, there is no authority to take away voting rights from the control shares of an acquiring person once those rights have been approved. If the stockholders do not grant voting rights to the control shares acquired by an acquiring person, those shares do not become permanent non-voting shares. The acquiring person is free to sell the shares to others. If the buyer or buyers of those shares themselves do not acquire a controlling interest, the shares are not governed by the control share law.

If control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of the voting power, a stockholder of record, other than the acquiring person, who did not vote in favor of approval of voting rights, is entitled to demand fair value for such stockholder's shares.

In addition to the control share law, Nevada has a business combination law, which prohibits certain business combinations between Nevada corporations and 'interested stockholders' for two years after the interested stockholder first becomes an interested stockholder, unless the corporation's board of directors approves the combination in advance. For purposes of Nevada law, an interested stockholder is any person who is: (a) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (b) an affiliate or associate of the corporation and at any time within the previous two years was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then-outstanding shares of the corporation. The definition of 'business combination' contained in the statute is sufficiently broad to cover virtually any kind of transaction that would allow a potential acquirer to use the corporation's assets to finance the acquisition or otherwise to benefit its own interests rather than the interests of the corporation and its other stockholders.

The effect of Nevada's business combination law is to potentially discourage parties interested in taking control of the Company from doing so if it cannot obtain the approval of our board of directors.

Anti-Takeover Effects of Provisions of Our Articles of Incorporation and Bylaws

Our articles of incorporation provide for a classified board of directors. This provision could prevent a party who acquires control of a majority of our outstanding common stock from obtaining control of the board until our second annual stockholders meeting following the date the acquirer obtains the controlling stock interest. The classified board provision could have the effect of discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us and could increase the likelihood that incumbent directors will retain their positions. In addition, under our amended and restated bylaws, directors may be removed only for cause and only by the affirmative vote of the holders of at least 80% of the voting power of our then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.

Our amended and restated bylaws also provide that stockholders may only act at meetings of stockholders and not by written consent in lieu of a stockholders' meeting. Our amended and restated bylaws provide that stockholders may not call a special meeting of stockholders. Rather, only the Chairman of our board of directors, the President, or the board of directors pursuant to a resolution approved by a majority of the entire board of directors are able to call special meetings of stockholders. These provisions may discourage another person or entity from making a tender offer,

24

Table of Contents

even if it acquired a majority of our outstanding voting stock, because the person or entity could only take action at a duly called stockholders' meeting relating to the business specified in the notice of meeting and not by written consent.

Our amended and restated bylaws also provide that stockholders may only conduct business at special meetings of stockholders that was specified in the notice of the meeting, and a stockholder must notify us in writing, within timeframes specified in our bylaws, of any stockholder nomination of a director and of any other business that the stockholders intends to bring at a meeting of stockholders. Our amended and restated bylaws also provide that our bylaws may be amended by our board of directors or by the affirmative vote of at least 80% of our voting stock then outstanding. These provisions could have the effect of discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us because the foregoing provisions may limit the proposals that may be acted upon at a stockholders' meeting, and the amendment provisions in our bylaws make such provisions difficult to change.

Listing on The Nasdaq Capital Market

Our common stock is listed on the Nasdaq Capital Market under the symbol 'NVIV.' On February 20, 2020, the reported closing price per share of our common stock on the Nasdaq Capital Market was $7.07.

Authorized but Unissued Shares

The authorized but unissued shares of common stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing requirements of the Nasdaq Capital Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust Company.

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering shares of common stock, together with warrants (the 'Series A warrants') to purchase shares of common stock. We are also offering pre-funded warrants (the 'Series B pre-funded warrants' and collectively with the Series A warrants, the 'warrants') to those purchasers, whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering in lieu of the shares of our common stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Series B pre-funded warrant will be exercisable for one share of common stock. Each Series B pre-funded warrant is being issued together with the same Series A warrant described above being issued with each share common stock. The shares of common stock or Series B pre-funded warrants, as the case may be, and the Series A warrants, can only be purchased together in this offering, but the Series B pre-funded warrants and Series A warrants are immediately separable and will be issued separately in this offering. We are also registering the shares of common stock and the shares of common stock issuable from time to time upon exercise of the Series B pre-funded warrants and Series A warrants offered hereby.

Common Stock

The description of our common stock under the section 'Description of Our Capital Stock' in this prospectus is incorporated herein by reference.

Series B Pre-Funded Warrants

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

Duration and Exercise Price

Each Series B pre-funded warrant offered hereby will have an initial exercise price per share equal to $0.01. The Series B pre-funded warrants will be immediately exercisable and will expire years from the date of issuance, subject to earlier call rights exercisable by the Company under specified circumstances. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Series B pre-funded warrants will be issued separately from the accompanying Series A warrants with Series B pre-funded warrants.

Exercisability

The Series B pre-funded warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Series B pre-funded warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days' prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding stock after exercising the holder's Series B pre-funded warrants up to 9.99% of the number of shares of our

26

Table of Contents

common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Series B pre-funded warrants and Nevada law. Purchasers of Series B pre-funded warrants in this offering may also elect prior to the issuance of the Series B pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding common stock.

Cashless Exercise

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

Transferability

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

Fractional Shares

No fractional shares of common stock will be issued upon the exercise of the Series B pre-funded warrants. Rather, the number of shares of common stock to be issued will be rounded to the nearest whole number.

Trading Market

There is no trading market available for the Series B pre-funded warrants on any securities exchange or nationally recognized trading system, and we do not expect a trading market to develop. We do not intend to list the Series B pre-funded warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the Series B pre-funded warrants will be extremely limited. The common stock issuable upon exercise of the Series B pre-funded warrants is currently listed on the Nasdaq Capital Market.

Right as a Stockholder

Except as otherwise provided in the Series B pre-funded warrants or by virtue of such holder's ownership of shares of our common stock, the holders of the Series B pre-funded warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their Series B pre-funded warrants. The Series B pre-funded warrants will provide that holders have the right to participate in distributions or dividends paid on our common stock.

Fundamental Transaction

In the event of a fundamental transaction, as described in the Series B 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 Series B pre-funded warrants will be entitled to receive upon exercise of the Series B pre-funded warrants the kind and amount of securities, cash or

27

Table of Contents

other property that the holders would have received had they exercised the Series B pre-funded warrants immediately prior to such fundamental transaction.

Series A warrants

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

Duration and Exercise Price

Each Series A warrant offered hereby will have an initial exercise price equal to $ per share of common stock. The Series A warrants will be immediately exercisable and will expire years from the date of issuance. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Series A warrants will be issued separately from the common stock, or the Series B pre-funded warrants, as the case may be.

Exercisability

The Series A warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Series A warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days' prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding stock after exercising the holder's Series A warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Series A warrants and Nevada law.

Cashless Exercise

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

Fractional Shares

No fractional shares of common stock will be issued upon the exercise of the Series A warrants. Rather, the number of shares of common stock to be issued will be rounded to the nearest whole number.

Transferability

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

We do not intend to list the Series A warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the Series A warrants will be extremely limited. The common stock issuable upon exercise of the Series A warrants is currently listed on the Nasdaq Capital Market.

Right as a Stockholder

Except as otherwise provided in the Series A warrants or by virtue of such holder's ownership of shares of our common stock, the holders of the Series A warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their Series A warrants.

Fundamental Transaction

In the event of a fundamental transaction, as described in the Series A 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 Series A warrants will be entitled to receive upon exercise of the Series A warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Series A warrants immediately prior to such fundamental transaction. In addition, in the event of a fundamental transaction which is approved by our Board, the holders of the Series A warrants have the right to require us or a successor entity to redeem the Series A warrant for cash in the amount of the Black-Scholes value of the unexercised portion of the Series A warrant on the date of the consummation of the fundamental transaction. In the event of a fundamental transaction which is not approved by our Board, the holders of the Series A warrants have the right to require us or a successor entity to redeem the Series A warrant for the consideration paid in the fundamental transaction in the amount of the Black Scholes value of the unexercised portion of the Series A warrant on the date of the consummation of the fundamental transaction.

MATERIAL U.S. FEDERAL TAX CONSIDERATIONS FOR HOLDERS OF OUR COMMON STOCK, SERIES B PRE-FUNDED WARRANTS AND SERIES A WARRANTS

The following discussion describes the material U.S. federal income and estate tax consequences of the acquisition, ownership and disposition of our common stock, Series B pre-funded warrants and Series A warrants acquired in this offering. This discussion is based on the current provisions of the Internal Revenue Code of 1986, as amended (referred to as the 'Code'), existing and proposed U.S. Treasury regulations promulgated thereunder, and administrative rulings and court decisions in effect as of the date hereof, all of which are subject to change at any time, possibly with retroactive effect. No ruling has been or will be sought from the Internal Revenue Service, or IRS, with respect to the matters discussed below, and there can be no assurance the IRS will not take a contrary position regarding the tax consequences of the acquisition, ownership or disposition of our common stock, Series B pre-funded warrants or Series A warrants, or that any such contrary position would not be sustained by a court.

We assume in this discussion that the shares of our common stock, Series B pre-funded warrants and Series A warrants will be held as capital assets (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxes, does not discuss the potential application of the Medicare contribution tax, the alternative minimum tax and does not deal with state or local taxes or U.S. federal gift and estate tax laws, except as specifically provided below with respect to non-U.S. holders, or any non-U.S. tax consequences that may be relevant to holders in light of their particular circumstances. This discussion also does not address the special tax rules applicable to particular holders, such as:

• financial institutions;

• brokers or dealers in securities;

• tax-exempt organizations;

• pension plans;

• regulated investment companies;

• owners that hold our common stock, Series B pre-funded warrants or Series A warrants as part of a straddle, hedge, conversion transaction, synthetic security or other integrated investment;

• insurance companies;

• controlled foreign corporations, passive foreign investment companies, or corporations that accumulate earnings to avoid U.S. federal income tax; and

• certain U.S. expatriates.

In addition, this discussion does not address the tax treatment of partnerships or other pass-through entities or persons who hold our common stock, Series B pre-funded warrants or Series A warrants through partnerships or other entities which are pass-through entities for U.S. federal income tax purposes. A partner in a partnership or other pass-through entity that will hold our common stock, Series B pre-funded warrants or Series A warrants should consult his, her or its own tax advisor regarding the tax consequences of the ownership and disposition of our common stock, Series B pre-funded warrants or Series A warrants through a partnership or other pass-through entity, as applicable.

The discussion of U.S. federal income and estate tax considerations is for information purposes only and is not tax advice. Prospective investors should consult their own tax advisors regarding the U.S. federal, state, local and non-U.S. income and other tax considerations of acquiring, holding and disposing of our common stock, Series B pre-funded warrants and Series A warrants.

30

Table of Contents

For the purposes of this discussion, a 'U.S. Holder' means a beneficial owner of our common stock, Series B pre-funded warrants or Series A warrants that is for U.S. federal income tax purposes (a) an individual citizen or resident of the United States, (b) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes), created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (d) a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person. A 'Non-U.S. Holder' is, for U.S. federal income tax purposes, a beneficial owner of common stock, Series B pre-funded warrants or Series A warrants that is not a U.S. Holder or a partnership for U.S. federal income tax purposes.

Allocation of Purchase Price to Common Stock, Series B Pre-funded Warrants and Series A Warrants

For U.S. federal income tax purposes, a holder's acquisition of the Series A warrants and common stock or Series B pre-funded warrants, as applicable, will be treated as the acquisition of an 'investment unit' consisting of one share of common stock or one Series B pre-funded warrant, as applicable, and a Series A warrant to acquire one share of our common stock, subject to adjustment. The purchase price for each investment unit will be allocated between these two components in proportion to their relative fair market values at the time the investment unit is purchased by the holder. This allocation of the purchase price for each investment unit will establish the holder's initial tax basis for U.S. federal income tax purposes in the common stock or Series B pre-funded warrant, as applicable, and the Series A warrant included in each investment unit. The separation of the share of common stock or Series B pre-funded warrant, as applicable, and the Series A warrant included in each investment unit should not be a taxable event for U.S. federal income tax purposes. Each holder should consult his, her or its own tax advisor regarding the allocation of the purchase price for an investment unit.

Treatment of Series B Pre-Funded Warrants

Although it is not entirely free from doubt, a Series B pre-funded warrant should be treated as a share of our common stock for U.S. federal income tax purposes and a holder of Series B pre-funded warrants should generally be taxed in the same manner as a holder of common stock as described below. Accordingly, upon exercise, the holding period of a Series B pre-funded warrant should carry over to the share of common stock received. Similarly, the tax basis of the Series B pre-funded warrant should carry over to the share of common stock received upon exercise increased by the exercise price of $0.01. Each holder should consult his, her or its own tax advisor regarding the risks associated with the acquisition of an investment unit pursuant to this offering (including potential alternative characterizations). The balance of this discussion generally assumes that the characterization described above is respected for U.S. federal income tax purposes.

Tax Considerations Applicable to U.S. Holders

Exercise and Expiration of Series A Warrants

In general, a U.S. Holder will not recognize gain or loss for U.S. federal income tax purposes upon exercise of a warrant. The U.S. Holder will take a tax basis in the shares acquired on the exercise of a Series A warrant equal to the exercise price of the Series A warrant, increased by the U.S. Holder's adjusted tax basis in the Series A warrant exercised (as determined pursuant to the rules discussed above). The U.S. Holder's holding period in the shares of our common stock acquired on exercise of the Series A warrant will begin on the date of exercise of the Series A warrant, and will not include any period for which the U.S. Holder held the Series A warrant.

31

Table of Contents

In certain limited circumstances, a U.S. Holder may be permitted to undertake a cashless exercise of Series A warrants into our common stock. The U.S. federal income tax treatment of a cashless exercise of Series A warrants into our common stock is unclear, and the tax consequences of a cashless exercise could differ from the consequences upon the exercise of a Series A warrant described in the preceding paragraph. U.S. Holders should consult their own tax advisors regarding the U.S. federal income tax consequences of a cashless exercise of Series A warrants.

The lapse or expiration of a Series A warrant will be treated as if the U.S. Holder sold or exchanged the Series A warrant and recognized a capital loss equal to the U.S. Holder's tax basis in the Series A warrant. The deductibility of capital losses is subject to limitations.

Certain Adjustments to and Distributions on the Series A Warrants

Under Section 305 of the Code, an adjustment to the number of shares of common stock issued on the exercise of the Series A warrants, or an adjustment to the exercise price of the Series A warrants, may be treated as a constructive distribution to a U.S. Holder of the Series A warrants if, and to the extent that, such adjustment has the effect of increasing such U.S. Holder's proportionate interest in our 'earnings and profits' or assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to our shareholders). In addition, if we were to make a distribution in cash or other property with respect to our common stock after the issuance of the Series A warrants, then we may, in certain circumstances, make a corresponding distribution to a Series A warrant holder. The taxation of a distribution received with respect to a Series A warrant is unclear. It is possible such a distribution would be treated as a distribution (or constructive distribution), although other treatments are possible. For more information regarding the tax considerations related to distributions, see the discussion below regarding 'Distributions.' U.S. Holders should consult their tax advisors regarding the proper treatment of any adjustments to and adjustments on the Series A warrants.

Distributions

As discussed above, we currently anticipate that we will retain future earnings for the development, operation, and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In the event that we do make distributions on our common stock or Series B pre-funded warrants to a U.S. Holder, those distributions generally will constitute dividends for U.S. tax purposes to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital that is applied against and reduces, but not below zero, a U.S. Holder's adjusted tax basis in our common stock or Series B pre-funded warrant, as applicable. Any remaining excess will be treated as gain realized on the sale or exchange of our common stock or Series B pre-funded warrant as described below under the section titled '-Gain on Disposition of Our Common Stock, Series B Pre-Funded Warrants or Series A Warrants.'

Gain on Disposition of Our Common Stock, Series B Pre-Funded Warrants or Series A Warrants

Upon a sale or other taxable disposition of our common stock, Series B pre-funded warrants or Series A warrants, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. Holder's adjusted tax basis in the common stock, Series B pre-funded warrants or Series A warrants. Capital gain or loss will constitute long-term capital gain or loss if the U.S. Holder's holding period for the common stock, Series B pre-funded warrant or Series A warrant exceeds one year. The deductibility of capital losses is subject to certain limitations. U.S. Holders who recognize losses with respect to a disposition of our common stock, Series B pre-funded warrants or Series A warrants should consult their own tax advisors regarding the tax treatment of such losses.

32

Table of Contents

Information Reporting and Backup Withholding

Information reporting requirements generally will apply to payments of dividends (including constructive dividends) on our common stock, Series B pre-funded warrants and Series A warrants and to the proceeds of a sale or other disposition of common stock, Series A warrants and Series B pre-funded warrants by a U.S. Holder unless such U.S. Holder is an exempt recipient, such as a corporation. Backup withholding will apply to those payments if the U.S. Holder fails to provide the holder's taxpayer identification number, or certification of exempt status, or if the holder otherwise fails to comply with applicable requirements to establish an exemption. Backup withholding is not an additional tax. Rather, any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against the U.S. Holder's U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Tax Considerations Applicable to Non-U.S. Holders

Exercise and Expiration of Series A Warrants

In general, a Non-U.S. Holder will not be subject to U.S. federal income tax on the exercise of the Series A warrants into shares of common stock. The U.S. federal income tax treatment of a cashless exercise of Series A warrants into our common stock is unclear. A Non-U.S. Holder should consult his, her, or its own tax advisor regarding the U.S. federal income tax consequences of a cashless exercise of Series A warrants.

The expiration of a Series A warrant will be treated as if the Non-U.S. Holder sold or exchanged the Series A warrant and recognized a capital loss equal to the Non-U.S. Holder's tax basis in the Series A warrant. However, a Non-U.S. Holder will not be able to utilize a loss recognized upon expiration of a Series A warrant against the Non-U.S. Holder's U.S. federal income tax liability unless the loss is effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if an income tax treaty applies, is attributable to a permanent establishment or fixed base in the United States) or is treated as a U.S.-source loss and the Non-U.S. Holder is individual nonresident and present 183 days or more in the taxable year of disposition in the United States and certain other conditions are met.

Certain Adjustments to and Distributions on the Series A Warrants

As described under '-U.S. Holders-Certain Adjustments and Distributions on to the Series A Warrants,' an adjustment to the Series A warrants could result in a constructive distribution to a Non-U.S. Holder, which would be treated as described under 'Distributions' below, and the tax treatment of a distribution on a warrant is unclear. Any resulting withholding tax attributable to deemed dividends would be collected from other amounts payable or distributable to the Non-U.S. Holder. Non-U.S. Holders should consult their tax advisors regarding the proper treatment of any adjustments to and distributions on the Series A warrants.

Distributions

As discussed above, we currently anticipate that we will retain future earnings for the development, operation, and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In the event that we do make distributions on our common stock or Series B pre-funded warrants to a Non-U.S. Holder, those distributions generally will constitute dividends for U.S. federal income tax purposes as described in '-U.S. Holders-Distributions.'

Any distribution (including constructive distributions) on our common stock or Series B pre-funded warrants that is treated as a dividend paid to a Non-U.S. Holder that is not effectively connected with the holder's conduct of a trade or business in the United States will generally be subject to withholding

33

Table of Contents

tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and the Non-U.S. Holder's country of residence. To obtain a reduced rate of withholding under a treaty, a Non-U.S. Holder generally will be required to provide the applicable withholding agent with a properly executed IRS Form W-8BEN, IRS Form W-8BEN-E or other appropriate form, certifying the Non-U.S. Holder's entitlement to benefits under that treaty. Such form must be provided prior to the payment of dividends and must be updated periodically. If a Non-U.S. Holder holds stock through a financial institution or other agent acting on the holder's behalf, the holder will be required to provide appropriate documentation to such agent. The holder's agent may then be required to provide certification to the applicable withholding agent, either directly or through other intermediaries. If a Non-U.S. Holder is eligible for a reduced rate of U.S. withholding tax under an income tax treaty, such Non-U.S. Holder should consult with its tax advisor to determine if it is able to obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for a refund with the IRS.

We generally are not required to withhold tax on dividends paid (or constructive dividends deemed paid) to a Non-U.S. Holder that are effectively connected with such holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that the holder maintains in the United States) if a properly executed IRS Form W-8ECI, stating that the dividends are so connected, is furnished to us (or, if stock is held through a financial institution or other agent, to the applicable withholding agent). In general, such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates applicable to U.S. persons. A corporate Non-U.S. Holder receiving effectively connected dividends may also be subject to an additional 'branch profits tax,' which is imposed, under certain circumstances, at a rate of 30% (or such lower rate as may be specified by an applicable treaty) on the corporate Non-U.S. Holder's effectively connected earnings and profits, subject to certain adjustments.

See also the sections below titled '-Information Reporting and Backup Withholding' and '-Foreign Accounts' for additional withholding rules that may apply to dividends paid to certain foreign financial institutions or non-financial foreign entities.

Gain on Disposition of Our Common Stock, Series B Pre-Funded Warrants or Series A Warrants

Subject to the discussions below under the sections titled '-Information Reporting and Backup Withholding' and '-Foreign Accounts,' a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax with respect to gain realized on a sale or other disposition of our common stock, Series B pre-funded warrants or Series A warrants unless

• the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business in the United States, and if an applicable income tax treaty so provides, the gain is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States; in these cases, the Non-U.S. Holder will be taxed on a net income basis at the regular graduated rates and in the manner applicable to U.S. persons, and if the Non-U.S. Holder is a corporation, an additional branch profits tax at a rate of 30%, or a lower rate as may be specified by an applicable income tax treaty, may also apply;

• the Non-U.S. Holder is a nonresident alien present in the United States for 183 days or more in the taxable year of the disposition and certain other requirements are met, in which case the Non-U.S. Holder will be subject to a 30% tax (or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder's country of residence) on the net gain derived from the disposition, which may be offset by certain U.S.-source capital losses of the Non-U.S. Holder, if any; or

34

Table of Contents

• we are, or have been at any time during the five-year period preceding such disposition (or the Non-U.S. Holder's holding period of the common stock, Series B pre-funded warrants or Series A warrants, if shorter), a 'U.S. real property holding corporation,' unless our common stock is regularly traded on an established securities market and the Non-U.S. Holder held no more than 5% of our outstanding common stock, directly or indirectly, during the shorter of the five-year period ending on the date of the disposition or the period that the Non-U.S. Holder held our common stock. Special rules may apply to the determination of the 5% threshold in the case of a holder of a Series B pre-funded warrant or Series A warrant. Non-U.S. Holders are urged to consult their own tax advisors regarding the effect of holding our Series B pre-funded warrants or Series A warrants on the calculation of such 5% threshold. Generally, a corporation is a 'U.S. real property holding corporation' if the fair market value of its 'U.S. real property interests' (as defined in the Code and applicable regulations) equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Although there can be no assurance, we believe that we are not currently, and we do not anticipate becoming, a 'U.S. real property holding corporation' for U.S. federal income tax purposes. No assurance can be provided that our common stock will be regularly traded on an established securities market for purposes of the rules described above.

See the sections titled '-Information Reporting and Backup Withholding' and '-Foreign Accounts' below for additional information regarding withholding rules that may apply to proceeds of a disposition of our common stock, Series B pre-funded warrants or Series A warrants paid to foreign financial institutions or non-financial foreign entities.

Information Reporting and Backup Withholding

We must report annually to the IRS and to each Non-U.S. Holder the gross amount of the distributions (including constructive distributions) on our common stock, Series B pre-funded warrants or Series A warrants paid to such holder and the tax withheld, if any, with respect to such distributions. Non-U.S. Holders may have to comply with specific certification procedures to establish that the holder is not a U.S. person (as defined in the Code) in order to avoid backup withholding at the applicable rate, currently 24%, with respect to dividends (including constructive dividends) on our common stock, Series B pre-funded warrants, or Series A warrants. Generally, a Non-U.S. Holder will comply with such procedures if it provides a properly executed IRS Form W-8BEN (or other applicable Form W-8) or otherwise meets documentary evidence requirements for establishing that it is a Non-U.S. Holder, or otherwise establishes an exemption. Dividends paid to Non-U.S. Holders subject to withholding of U.S. federal income tax, as described above under the heading '-Distributions,' will generally be exempt from U.S. backup withholding.

Information reporting and backup withholding generally will apply to the proceeds of a disposition of our common stock, Series B pre-funded warrants or Series A warrants by a Non-U.S. Holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the Non-U.S. Holder certifies its status as a Non-U.S. Holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a Non-U.S. Holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker. Non-U.S. Holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the Non-U.S. Holder resides or is incorporated under the provisions of a specific treaty or agreement.

35

Table of Contents

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a Non-U.S. Holder can be refunded or credited against the Non-U.S. Holder's U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS.

Foreign Accounts

The Foreign Account Tax Compliance Act, or FATCA, generally imposes a 30% withholding tax on dividends on, and gross proceeds from the sale or other disposition of, common stock, Series B pre-funded warrants and Series A warrants if paid to a non-U.S. entity unless (i) if the non-U.S. entity is a 'foreign financial institution,' the non-U.S. entity undertakes certain due diligence, reporting, withholding, and certification obligations, (ii) if the non-U.S. entity is not a 'foreign financial institution,' the non-U.S. entity identifies certain of its U.S. investors, if any, or (iii) the non-U.S. entity is otherwise exempt under FATCA.

Withholding under FATCA generally applies to payments of dividends on our common stock, Series B pre-funded warrants and Series A warrants. While withholding under FATCA may apply to payments of gross proceeds from a sale or other disposition of our common stock, Series B pre-funded warrants and Series A warrants, under recently proposed U.S. Treasury Regulations, withholding on payments of gross proceeds is not required. Although such regulations are not final, applicable withholding agents may rely on the proposed regulations until final regulations are issued.

An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this section. Under certain circumstances, a holder may be eligible for refunds or credits of the tax. Holders should consult their own tax advisors regarding the possible implications of FATCA on their investment in our common stock, Series B pre-funded warrants or Series A warrants.

Federal Estate Tax

Common stock or Series B pre-funded warrants owned or treated as owned by an individual who is a Non-U.S. Holder (as specially defined for U.S. federal estate tax purposes) at the time of death will be included in the individual's gross estate for U.S. federal estate tax purposes and, therefore, may be subject to U.S. federal estate tax, unless an applicable estate tax or other treaty provides otherwise. The foregoing may also apply to Series A warrants.

The preceding discussion of material U.S. federal tax considerations is for information only. It is not tax advice. Prospective investors should consult their own tax advisors regarding the particular U.S. federal, state, local and non-U.S. tax consequences of purchasing, holding and disposing of our common stock, Series B pre-funded warrants or Series A warrants, including the consequences of any proposed changes in applicable laws.

Determination of Offering Price

The combined public offering price per share and Series A warrant and the combined public offering price per Series B pre-funded warrant and Series A warrant we are offering and the exercise prices and other terms of the warrants were negotiated between us and the investors, in consultation with the placement agent based on the trading of our common stock prior to this offering, among other things.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Nevada Revised Statutes ('NRS') Sections 78.7502 and 78.751 provide us with the power to indemnify any of our directors, officers, employees and agents. The person entitled to indemnification must have conducted himself in good faith, and must reasonably believe that his conduct was in, or not opposed to, our best interests. In a criminal action, the director, officer, employee or agent must also not have had reasonable cause to believe that his conduct was unlawful. In addition, any of our directors, officers, employees or agents are entitled to indemnification if such person is successful on the merits or otherwise in defense of any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative against actual and reasonable expenses incurred in connection with defending such action.

Under NRS Section 78.751, advances for expenses may be made by agreement if the director or officer affirms in writing to repay the expenses if it is determined that such officer or director is not entitled to be indemnified.

Our bylaws include an indemnification provision under which we have the power to indemnify our directors, officers, former directors and officers, employees and other agents (including heirs and personal representatives) against all costs, charges and expenses actually and reasonably incurred, including an amount paid to settle an action or satisfy a judgment to which a director or officer is made a party by reason of being or having been a director or officer of our Company. Our bylaws further provide for the advancement of all expenses incurred in connection with a proceeding upon receipt of an undertaking by or on behalf of such person to repay such amounts unless it is determined that the party is entitled to be indemnified under our bylaws. No advance will be made by us to a party if it is determined that the party acted in bad faith. These indemnification rights are contractual, and as such will continue as to a person who has ceased to be a director, officer, employee or other agent, and will inure to the benefit of the heirs, executors and administrators of such a person. Unless our articles are amended to provide for greater liability, neither our directors nor officers are individually liable to us or our stockholders or creditors for any act or omission as a director or officer unless it is proven that: (i) such act or omission constituted a breach of such director's or officer's fiduciary duties; and

Table of Contents

(ii) such breach involved intentional misconduct, fraud or a knowing violation of law. These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act of 1933, as amended, in which case such provisions are against public policy as expressed such Act and are therefore unenforceable.

We maintain an insurance policy on behalf of our directors and officers, covering certain liabilities which may arise as a result of the actions of the directors and officers.

We have entered into an indemnification agreement with each of our officers and directors pursuant to which they will be indemnified by us, subject to certain limitations, for any liabilities incurred by them in connection with their role as officers and/or directors of the Company.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

During the past three years, the registrant has sold the following securities which were not registered under the Securities Act of 1933, as amended, or the 'Securities Act'.

As consideration for the services provided to us by H.C. Wainwright & Co., LLC ('Wainwright') as placement agent for our November 2019 public offering (the '2019 Offering') of our common stock, $0.00001 par value per share, we agreed, subject to the approval by our stockholders of an increase to the authorized number of shares of our common stock, to issue to Wainwright, or its designees, placement agent warrants (the 'Placement Agent Warrants') to purchase an aggregate of 15,168 shares of common stock. On January 21, 2020, our stockholders approved an increase to our authorized shares of common stock and we subsequently issued the Placement Agent Warrants. The Placement Agent Warrants have an exercise price of $4.50 per share, are immediately exercisable and expire 5 years from the date of the 2019 Offering.

On September 25, 2019, pursuant to the terms of our 2015 Equity Incentive Plan (the 'Plan'), we granted 2,300 shares of our restricted common stock to Richard Toselli, our Chief Executive Officer, and 1,584 shares of our restricted common stock to Richard Christopher, our Chief Financial Officer, in consideration of Dr. Toselli's and Mr. Christopher's service as officers. These shares of restricted stock were issued under the Plan. We filed a registration statement on Form S-8 (File No. 333-234630) to register these shares of restricted common stock for resale on November 12, 2019.

On January 14, 2019, we granted to Mr. Christopher, as our new Chief Financial Offer, a stock option to purchase 3,000 shares of our common stock with an exercise price of $45.90 per share. The option was granted as an inducement grant made outside of the Plan in accordance with Nasdaq Listing Rule 5635(c)(4) and in reliance upon the exemption from the registration requirements of the Securities Act. The option has a ten-year term and vested as to one-third (1/3) of the shares on January 14, 2020, and will continue to vest as to one third (1/3) of the shares on January 14, 2021 and the remaining one third (1/3) of the shares on January 14, 2022. There are also provisions allowing for acceleration of vesting if certain conditions are met, and vesting is subject to Mr. Christopher's continued service with our company through the applicable vesting date. We filed a registration statement on Form S-8 (File No. 333-230644) to register the shares of Common Stock underlying the option on April 1, 2019.

On January 25, 2018, we entered into a purchase agreement, or the Purchase Agreement, with Lincoln Park Capital Fund, LLC, or Lincoln Park, which provided that, upon the terms and subject to the conditions and limitations set forth in the Purchase Agreement, Lincoln Park committed to purchase up to an aggregate of $15 million of shares of our common stock over the 24-month term of the Purchase Agreement. We terminated the Purchase Agreement on May 9, 2019. We issued 574 shares of common stock to Lincoln Park in consideration for entering into the Purchase Agreement, and from January 2018 through the date of termination, we sold 8,561 shares of common stock under the Purchase Agreement, generating net proceeds of approximately $3.1 million.

On August 10, 2017, we issued an aggregate of 2,696 shares of common stock to certain holders of warrants, dated May 9, 2014, in exchange for their warrants to purchase an aggregate of 771 shares of common stock.

Table of Contents

Unless otherwise noted, all of the transactions described in Item 15 were exempt from registration under the Securities Act pursuant to Section 4(a)(2) of the Securities Act in that such sales did not involve a public offering, under Rule 701 promulgated under the Securities Act, in that they were offered and sold either pursuant to written compensatory plans or pursuant to a written contract relating to compensation, as provided by Rule 701, or under Rule 506 of Regulation D promulgated under the Securities Act, and no underwriters were involved in the issuance of securities.

ITEM 17. UNDERTAKINGS.

The undersigned registrant hereby undertakes:

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

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the 'Securities Act');

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which,

Table of Contents

individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the 'Calculation of Registration Fee' table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the 'Exchange Act'), that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5) That, for purposes of determining any liability under the Securities Act:

(i) the information omitted from the form of prospectus filed as part of the registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of the registration statement as of the time it was declared effective; and

(ii) each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Table of Contents

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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