PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information contained elsewhere in this prospectus supplement. This summary does not contain all the information that you should consider before investing in our Company. You should carefully read the entire prospectus supplement, including all documents incorporated by reference herein. In particular, attention should be directed to our “Risk Factors,” “Information With Respect to the Company,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements and related notes thereto contained herein or otherwise incorporated by reference hereto, before making an investment decision.

Business Overview

We are a medical device company developing tissue-based devices that are designed to be life sustaining or life enhancing for patients with cardiovascular disease, and peripheral arterial and venous disease. Our products are being developed to address large unmet medical needs by either offering treatments where none currently exist or by substantially increasing the current standards of care. Our products which we are developing include: the VenoValve®, a porcine based device to be surgically implanted in the deep venous system of the leg to treat a debilitating condition called chronic venous insufficiency (“CVI”); and the CoreoGraft®, a bovine based conduit to be used to revascularize the heart during coronary artery bypass graft (“CABG”) surgeries. Both of these products are currently being developed for approval by the U.S. Food and Drug Administration (“FDA”). Our current senior management team has been affiliated with more than 50 products that have received FDA approval or CE marking. We currently lease a 14,507 sq. ft. manufacturing facility in Irvine, California, where we manufacture products for our clinical trials and which has previously been FDA certified for commercial manufacturing of devices.

Each of our products will be required to successfully complete significant clinical trials to demonstrate the safety and efficacy of the product before it will be able to be approved by the FDA.

We are in the process of developing the following bioprosthetic implantable devices for peripheral vascular and cardiovascular disease:

VenoValve

The VenoValve is a porcine based valve developed at HJLI to be implanted in the deep venous system of the leg to treat severe CVI. By reducing reflux, and lowering venous hypertension, the VenoValve has the potential to reduce or eliminate the symptoms of deep venous, severe CVI, including venous leg ulcers. The current version of the VenoValve is designed to be surgically implanted into the patient via a 5 to 6 inch incision in the upper thigh.

There are presently no FDA approved medical devices to address valvular incompetence, or effective treatments for deep venous CVI. Current treatment options include compression garments, or constant leg elevation. These treatments are generally ineffective, as they attempt to alleviate the symptoms of CVI without addressing the underlying causes of the disease. In addition, we believe that compliance with compression garments and leg elevation is extremely low, especially among the elderly. Valve transplants from other parts of the body have been attempted, but with very-poor results. Many attempts to create substitute valves have also failed, usually resulting in early thromboses. The premise behind the VenoValve is that by reducing the underlying causes of CVI, reflux and venous hypertension, the debilitating symptoms of CVI will decrease, resulting in improvement in the quality of the lives of CVI sufferers.

We estimate that there are approximately 2.4 million people in the U.S. that suffer from deep venous CVI due to valvular incompetence.

VenoValve Clinical Status

After consultation with the FDA, and as a precursor to the U.S. pivotal trial, we conducted a small first-in-human study for the VenoValve in Colombia. The first-in-human Colombian trial included 11 patients. In addition to providing safety and efficacy data, the purpose of the first-in-human study was to provide proof of concept, and to provide valuable feedback to make any necessary product modifications or adjustments to our surgical implantation procedures for the VenoValve prior to conducting the U.S. pivotal trial. In December of 2018, we received regulatory approval from Instituto Nacional de Vigilancia de Medicamentos y Alimentos (“INVIMA”), the Colombian equivalent of the FDA. On February 19, 2019, we announced that the first VenoValve was successfully implanted in a patient in Colombia. Between April of 2019 and December of 2019, we successfully implanted VenoValves in 10 additional patients, completing the implantations for the Colombian first-in-human study. Overall, VenoValves have been implanted in all 11 patients. Endpoints for the VenoValve first-in-human study include safety (device related adverse events), reflux, measured by doppler, a VCSS score used by the clinician to measure disease severity, and a VAS score used by the patient to measure pain, and a quality of life measurement.

Final results from the first-in-human study were released in December of 2020. Among the 11 patients, reflux improved an average of 54%, Venous Clinical Severity Scores (“VCSSs”) improved an average of 56%, and visual analog scale (VAS) scores, which are used by patients to measure pain, improved an average of 76%, when compared to pre-surgery levels. VCSS scores are commonly used by clinicians in practice and in clinical trials to objectively assess outcomes in the treatment of venous disease, and include ten characteristics including pain, inflammation, skin changes such as pigmentation and induration, the number of active ulcers, and ulcer duration. The improvement in VCSS scores is significant and indicates that almost all of the VenoValve patients who had severe CVI pre-surgery, had mild CVI or the complete absence of disease at one-year post surgery. Quality of life measured by a VEINES score showed statistically significant improvement.

VenoValve safety incidences were minor with no reported device related adverse events. Minor non-device related adverse safety issues included one (1) fluid pocket (which was aspirated), intolerance from Coumadin anticoagulation therapy, three (3) minor wound infections (treated with antibiotics), and one occlusion due to patient non-compliance with anti-coagulation therapy.

In preparation for the VenoValve U.S. pivotal trial, we submitted a Pre-IDE filing with the FDA in October of 2020 and had a pre IDE meeting with the FDA on January 11, 2021. Topics presented at the meeting included the background and clinical need for the VenoValve, proposed U.S. pivotal study design, patient monitoring protocols for safety and efficacy, bench testing protocols used to develop the device, and the VenoValve first-in-human results. We received valuable feedback from the FDA in several areas during the Pre-IDE meeting and believe we reached consensus on many important issues.

An investigational device exemption or IDE from the FDA is required before a medical device company can proceed with a pivotal trial for a class III medical device. On March 5, 2021 we filed an IDE application with the FDA for the VenoValve U.S. pivotal trial. On April 1, 2021, twenty-seven days after filing the IDE application, we received notification from the FDA that our IDE application was approved. The U.S. pivotal for the VenoValve will be known at the SAVVE (Surgical Anti-reflux Veno Valve Endoprosthesis) study and is a prospective, non-blinded, single arm, multi-center study of seventy-five (75) CVI patients enrolled at up to 20 U.S. sites.

Endpoints for the SAVVE trial mirror those endpoints used for the first-in-human trial, and include the absence of material adverse safety events (mortality, deep wound infection, major bleeding, ipsilateral deep vein thrombosis, pulmonary embolism) at thirty (30) days post implantation, reductions of reflux at one hundred and eighty days (180) days post VenoValve implantation, VCSS scoring to measure disease manifestations, VAS scores to measure pain, and quality of life measurements. We have significant interest from key opinion leaders and several of the top vascular clinicians in the U.S. who would like to participate in the VenoValve U.S. pivotal trial. We are in the process of qualifying the sites, seeking investigational review board (“IRB”) and other necessary approvals, negotiating clinical trial agreements, and preparing for site training and initiations. At this point we expect the first implantation for the SAVVE study to occur during the third quarter of 2021.

On August 3, 2020, we announced that the FDA granted Breakthrough Device Designation status to the VenoValve. The FDA’s Breakthrough Devices Program was established to enable priority review for devices that provide more effective treatment or diagnosis of life threatening or irreversibly debilitating diseases or conditions. The goal of the FDA’s Breakthrough Devices Program is to provide patients and health care providers with timely access to medical devices by speeding up their development, assessment, and review, while preserving the FDA’s mission to protect and promote public health.

CoreoGraft

The CoreoGraft is a bovine based off the shelf conduit that could potentially be used to revascularize the heart, instead of harvesting the saphenous vein from the patient’s leg. In addition to avoiding the invasive and painful SVG harvest process, HJLI’s CoreoGraft closely matches the size of the coronary arteries, eliminating graft failures that occur due to size mismatch. In addition, with no graft harvest needed, the CoreoGraft could also reduce or eliminate the inner thickening that burdens and leads to failure of the SVGs.

In addition to providing a potential alternative to SVGs, the CoreoGraft could be used when making grafts from the patients’ own arteries and veins is not an option. For example, patients with significant arterial and vascular disease often do not have suitable vessels to be used as grafts. For other patients, such as women who have undergone radiation treatment for breast cancer and have a higher incidence of heart disease, using the LIMA may not be an option if it was damaged by the radiation. Another example are patients undergoing a second CABG surgery. Due in large part to early SVG failures, patients may need a second CABG surgery. If the SVG was used for the first CABG surgery, the patient may have insufficient veins to harvest. While the CoreoGraft may start out as a product for patients with no other options, if the CoreoGraft establishes good short term and long term patency rates, it could become the graft of choice for all CABG patients in addition to the LIMA.

CoreoGraft Clinical Status

In January of 2020, we announced the results of a six-month, nine sheep, animal feasibility study for the CoreoGraft. Bypasses were accomplished by attaching the CoreoGrafts from the ascending aorta to the left anterior descending artery, and surgeries were preformed both on-pump and off-pump. Partners for the feasibility study included the Texas Heart Institute, and American Preclinical Services.

Test subjects were evaluated via angiograms and flow monitors during the study, and a full pathology examination of the CoreoGrafts and the surrounding tissue was performed post necropsy.

The results from the feasibility study demonstrated that the CoreoGrafts remained patent (open) and fully functional at 30, 90, and 180 day intervals after implantation. In addition, pathology examinations of the grafts and surrounding tissue at the conclusion of the study showed no signs of thrombosis, infection, aneurysmal degeneration, changes in the lumen, or other problems that are known to plague and lead to failure of SVGs.

In addition to exceptional patency, pathology examinations indicated full endothelialization for grafts implanted for 180 days both throughout the CoreoGrafts and into the left anterior descending arteries. Endothelium is a layer of cells that naturally exist throughout healthy veins and arteries and that act as a barrier between blood and the surrounding tissue, which helps promote the smooth passage of blood. Endothelium are known to produce a variety anti-clotting and other positive characteristics that are essential to healthy veins and arteries. The presence of full endothelialization within the longer term CoreoGrafts indicates that the graft is being accepted and assimilated in a manner similar to natural healthy veins and arteries that exist throughout the vascular system and is an indication of long-term biocompatibility.

In May of 2020, we announced that we had received approval from the Superintendent of Health of the National Health Counsel for the Republic of Paraguay to conduct a first-in-human, feasibility trial for the CoreoGraft. Up to 5 patients that need coronary artery bypass graft surgery were to receive CoreoGraft implants as part of the first-in-human study. In July of 2020, we announced that we had received permission to proceed with the first-in-human study, which had been put on hold due to the COVID-19 pandemic, and in August of 2020 we announced that the first two patients had been enrolled for the first-in-human CoreoGraft trial. Heart bypass surgeries for the first two patients to receive CoreoGraft implants as part of our first-in-human trial were successfully completed in October of 2020. A third bypass surgery using the CoreoGraft was successfully completed in November of 2020 and another surgery was completed in December of 2020. Two CoreoGraft surgical patients have expired due to non-device related adverse events, one in October and one in November of 2020. As a result of these deaths, the feasibility study was put on hold, pending a review by an ethics committee that oversees the feasibility trial. Although the committee has given approval to resume with the feasibility study, due to the recent resurgence of COVID-19 in South America (including in Paraguay), the first-in-human CoreoGraft feasibility trial remains on hold. At this time we have no further information as to when the study might resume.

THE OFFERING

RISK FACTORS

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risk factors we describe in this prospectus supplement and in any related free writing prospectus that we may authorize to be provided to you or in any report incorporated by reference into this prospectus supplement, including our Annual Report on Form 10-K for the year ended December 31, 2020, or any Annual Report on Form 10-K or Quarterly Report on Form 10-Q that is incorporated by reference into this prospectus supplement after the date of this prospectus supplement. Although we discuss key risks in those risk factor descriptions, additional risks not currently known to us or that we currently deem immaterial also may impair our business. Our subsequent filings with the SEC may contain amended and updated discussions of significant risks. We cannot predict future risks or estimate the extent to which they may affect our financial performance.

Risks Related to This Offering

Since we have some discretion in how we use the proceeds from this offering, we may use the proceeds in ways with which you disagree.

We have not allocated specific amounts of the net proceeds from this offering for any specific purpose. Accordingly, our management will have some flexibility in applying the net proceeds of this offering. You will be relying on the judgment of our management with regard to the use of these net proceeds and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that the net proceeds will be invested in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flow.

You may experience immediate and substantial dilution.

The offering price per share in this offering may exceed the net tangible book value per share of our common stock outstanding prior to this offering. Assuming that an aggregate of $25,000,000 of shares of our common stock are sold during the term of the At Market Issuance Sales Agreement with Ladenburg at a price of $6.00 per share, the last reported sale price of our common stock on The NASDAQ Capital Market on August 10, 2021, for aggregate net proceeds of approximately $24.0 million after deducting commissions and estimated aggregate offering expenses payable by us, you will experience immediate dilution of $0.88 per share, representing the difference between our as adjusted pro forma net tangible book value per share as of June 30, 2021 after giving effect to this offering and the assumed offering price. The exercise of outstanding stock options and warrants may result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering.

The actual number of shares we will issue under the sales agreement with Ladenburg, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement with Ladenburg and compliance with applicable law, we have the discretion to deliver placement notices to Ladenburg at any time throughout the term of the sales agreement. The number of shares that are sold by Ladenburg after delivering a placement notice will fluctuate based on the market price of the Common Stock during the sales period and limits we set with Ladenburg.

There is a limited trading market for our Common Stock, which could make it difficult to liquidate an investment in our Common Stock, in a timely manner.

Our Common Stock is currently traded on The Nasdaq Capital Market. Because there is a limited public market for our Common Stock, investors may not be able to liquidate their investment whenever desired. We cannot assure that there will be an active trading market for our common stock and the lack of an active public trading market could mean that investors may be exposed to increased risk. In addition, if we failed to meet the criteria set forth in SEC regulations, various requirements would be imposed by law on broker-dealers who sell our securities to persons other than established customers and accredited investors. Consequently, such regulations may deter broker-dealers from recommending or selling our Common Stock, which may further affect its liquidity.

We do not anticipate declaring any cash dividends on our common stock which may adversely impact the market price of our stock.

We have never declared or paid cash dividends on our common stock and do not plan to pay any cash dividends in the near future. Our current policy is to retain all funds and any earnings for use in the operation and expansion of our business. If we do not pay dividends, our stock may be less valuable to you because a return on your investment will only occur if our stock price appreciates.

Sales of a significant number of shares of our common stock in the public markets, or the perception that such sales could occur, could depress the market price of our common stock.

Sales of a significant number of shares of our common stock in the public markets, or the perception that such sales could occur as a result of our utilization of a universal shelf registration statement, our At Market Issuance Sales Agreement with Ladenburg or otherwise could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock or the market perception that we are permitted to sell a significant number of our securities would have on the market price of our common stock.

The market price for our securities may be volatile, which could result in substantial losses to investors.

The market price for our common stock may be volatile and subject to wide fluctuations in response to factors including the following:

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. As a result, to the extent shareholders sell our securities in negative market fluctuation, they may not receive a price per share that is based solely upon our business performance. We cannot guarantee that shareholders will not lose some of their entire investment in our securities.

USE OF PROCEEDS

We currently intend to use the net proceeds to us from this offering primarily for the continued development of our two lead products, VenoValve and the CoreoGraft, and for general corporate purposes, including working capital and investing in or acquiring companies that are synergistic with or complementary to our technologies. The amounts and timing of these expenditures will depend on numerous factors, including the development of our current business initiatives. This expected use of our net proceeds from this offering represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors, including the status of and results from clinical trials and any unforeseen cash needs. Accordingly, we will have broad discretion over the uses of the net proceeds from this offering and investors will be relying on the judgment of our management regarding the application of the net proceeds from this offering. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. Pending these uses, we intend to invest the net proceeds from this offering in short-term, investment-grade interest-bearing securities such as money market funds, certificates of deposit, commercial paper and guaranteed obligations of the U.S. government.

DILUTION

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the public offering price per share and the adjusted net tangible book value per share of our common stock after this offering.

Our net tangible book value on June 30, 2021 was approximately $40.9 million, or $4.80 per share. “Net tangible book value” is total assets minus the sum of liabilities and intangible assets. “Net tangible book value per share” is net tangible book value divided by the total number of shares outstanding.

After giving effect to the sale of shares of our common stock in the aggregate amount of $25,000,000 in this offering at an assumed offering price of $6.00 per share, which was the last reported sale price of our common stock on The NASDAQ Capital Market on August 10, 2021, and after deducting estimated offering commissions and expenses payable by us, our net tangible book value as of June 30, 2021 would have been approximately $64.9 million, or $5.12 per share of common stock. This represents an immediate increase in net tangible book value of $0.32 per share to our existing stockholders and an immediate dilution in net tangible book value of $0.88 per share to investors participating in this offering. The following table illustrates this dilution per share to investors participating in this offering:

The table above assumes, for illustrative purposes, that an aggregate of 4,166,666 shares of our common stock are sold at a price of $6.00 per share, the last reported sale price of our common stock on The NASDAQ Capital Market on August 10, 2021, for aggregate gross proceeds of $25,000,000. The shares sold in this offering, if any, will be sold from time to time at various prices.

The number of shares of our common stock that will be outstanding immediately after this offering as shown above is based on 8,513,662 shares outstanding as of the date of this prospectus supplement. The number of shares outstanding as of the date of this prospectus supplement, as used throughout this prospectus supplement, unless otherwise indicated, excludes the following, all as of the date of this prospectus supplement:

To the extent that any of our outstanding options or warrants are exercised, we grant additional options or other awards under our stock incentive plan or issue additional warrants, or we issue additional shares of common stock in the future, there may be further dilution.

The total number of shares of capital stock we are authorized to issue is 260,000,000 shares, of which (a) 250,000,000 shares are common stock and (b) 10,000,000 shares are preferred stock.

Common Stock

As of June 30, 2021, there were 8,513,662 shares of common stock issued and outstanding, held of record by approximately 79 stockholders. Subject to preferential rights with respect to any outstanding preferred stock, all outstanding shares of common stock are of the same class and have equal rights and attributes.

Dividend Rights

 Holders of the common stock may receive dividends when, as and if declared by our board of directors out of the assets legally available for that purpose and subject to the preferential dividend rights of any other classes or series of stock of our Company. We have never paid, and have no plans to pay, any dividends on our shares of common stock.

Voting Rights

Holders of the common stock are entitled to one vote per share in all matters as to which holders of common stock are entitled to vote. Holders of not less than a majority of the outstanding shares of common stock entitled to vote at any meeting of stockholders constitute a quorum unless otherwise required by law.

Election of Directors

Our amended and restated certificate of incorporation does not permit stockholders to cumulate their votes in the election of directors. Accordingly, the holders of a majority of the outstanding shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect. 

Liquidation

Upon liquidation, dissolution or winding up of our company, the assets legally available for distribution to stockholders are distributable ratably among the holders of our common stock after payment of liquidation preferences, if any, on any outstanding payment of other claims of creditors.

Redemption

The common stock is not redeemable or convertible and does not have any sinking fund provisions.

Preemptive Rights

Holders of the common stock do not have preemptive rights.

Other Rights

Our common stock is not liable to further calls or to assessment by the registrant and for liabilities of the registrant imposed on its stockholders under state statutes.

Right to Amend Bylaws

The board of directors has the power to adopt, amend or repeal the bylaws. The bylaws may be altered, amended or repealed, and new bylaws made, by the Board of Directors or by the affirmative vote of sixty-six and two-thirds percent of the outstanding voting power of the corporation.

Change in Control

Provisions of Delaware law and our certificate of incorporation and bylaws could make the acquisition of our company by means of a tender offer, proxy contest or otherwise, and the removal of incumbent officers and directors, more difficult. These provisions include:

Section 203 of the DGCL, which prohibits a merger with a 15%-or-greater stockholder, such as a party that has completed a successful tender offer, until three years after that party became a 15%-or-greater stockholder;

The authorization in our certificate of incorporation of undesignated preferred stock, which could be issued without stockholder approval in a manner designed to prevent or discourage a takeover; and

Provisions in our bylaws regarding rights to call a special meeting of stockholders limit such rights to the Chairman of the Board of Directors, the Chief Executive Officer or President, or by a resolution adopted by a majority of the whole Board of Directors, but such special meetings may not be called by any other person or persons, which could make it more difficult for stockholders to wage a proxy contest for control of our board of directors or to vote to repeal any of the anti-takeover provisions contained in our certificate of incorporation and bylaws. 

Together, these provisions may make the removal of management more difficult and may discourage transactions that could otherwise involve payment of a premium over prevailing market prices for our common stock.

Market, Symbol and Transfer Agent

Our common stock is listed for trading on the Nasdaq Capital Market under the symbol “HJLI”. The transfer agent and registrar for our common stock is VStock Transfer, LLC.

PLAN OF DISTRIBUTION

We have entered into sales agreement (the “Sales Agreement”) with Ladenburg under which we may issue and sell shares of our common stock having aggregate sales proceeds of up to $25,000,000 from time to time through Ladenburg acting as agent. Sales of our shares of common stock, if any, under this prospectus supplement and the accompanying prospectus will be made by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on or through the NASDAQ Capital Market or any other existing trading market for our common stock in the United States or to or through a market maker, subject to the limitations imposed by General Instruction I.B.6. to Form S-3, as applicable.

Each time we wish to issue and sell shares of common stock under the Sales Agreement, we will notify Ladenburg of the number of shares to be issued, the dates on which such sales are anticipated to be made, any limitation on the number of shares to be sold in any one day and any minimum price below which sales may not be made. Once we have so instructed Ladenburg, subject to the terms and conditions of the Sales Agreement, Ladenburg has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up to the amount specified on such terms. The obligations of Ladenburg under the Sales Agreement to sell our shares of common stock are subject to a number of conditions that we must meet.

Ladenburg will provide written confirmation to us following the close of trading on Nasdaq following each day in which shares of our common stock are sold under the Sales Agreement. Each confirmation will include the number of shares sold on the day, the aggregate gross sales proceeds, the net proceeds to us, and the compensation payable by us to Ladenburg with respect to the sales. The settlement of sales of shares between us and Ladenburg is generally anticipated to occur on the second trading day following the date on which the sale was made. Sales of our shares of common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Ladenburg may agree. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. We will report at least quarterly the number of shares of common stock sold through Ladenburg under the Sales Agreement, the net proceeds to us and the compensation paid by us to Ladenburg in connection with the sales of common stock.

We will pay Ladenburg a commission equal to 3.0% of the aggregate gross proceeds we receive from each sale of our shares of common stock. Because there is no minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. In addition, we have agreed to reimburse Ladenburg for the fees and disbursements of its counsel, payable upon execution of the Sales Agreement, in an amount not to exceed $75,000, in addition to certain ongoing disbursements of its legal counsel up to $3,000 per calendar quarter. We estimate that the total expenses for the offering, excluding any commissions or expense reimbursement payable to Ladenburg under the terms of the Sales Agreement, will be approximately $160,000, not including the $75,000 reimbursement to Ladenburg noted above. The remaining sale proceeds, after deducting any other transaction fees, will equal our net proceeds from the sale of such shares.

In connection with the sale of the shares of common stock on our behalf, Ladenburg will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of Ladenburg will be deemed to be underwriting commissions or discounts. We have agreed to indemnify Ladenburg against certain civil liabilities, including liabilities under the Securities Act. We have also agreed to contribute to payments Ladenburg may be required to make in respect of such liabilities.

The offering of our shares of common stock pursuant to the Sales Agreement will terminate upon the earlier of (i) August 12, 2023 and (ii) the termination of the Sales Agreement as permitted therein. We and Ladenburg may each terminate the Sales Agreement at any time with prior written notice.

This summary of the material provisions of the Sales Agreement does not purport to be a complete statement of its terms and conditions. A copy of the Sales Agreement is filed as an exhibit to our Current Report on Form 8-K filed under the Exchange Act on August 12, 2021 and incorporated by reference in this prospectus supplement.

Overview

Hancock Jaffe Laboratories, Inc. is a medical device company developing tissue based solutions that are designed to be life sustaining or life enhancing for patients with cardiovascular disease, and peripheral arterial and venous disease. The Company’s products are being developed to address large unmet medical needs by either offering treatments where none currently exist or by substantially increasing the current standards of care. Our two lead products which we are developing are: the VenoValve®, a porcine based device to be surgically implanted in the deep venous system of the leg to treat a debilitating condition called chronic venous insufficiency (“CVI”); and the CoreoGraft®, a bovine based conduit to be used to revascularize the heart during coronary artery bypass graft (“CABG”) surgeries. Both of our current products are being developed for approval by the U.S. Food and Drug Administration (“FDA”). We currently receive tissue for development of our products from one domestic supplier and one international supplier. Our current business model is to license, sell, or enter into strategic alliances with large medical device companies with respect to our products, either prior to or after FDA approval. Our current senior management team has been affiliated with more than 50 products that have received FDA approval or CE marking. We currently lease a 14,507 sq. ft. manufacturing facility in Irvine, California, where we manufacture products for our clinical trials and which has previously been FDA certified for commercial manufacturing of product.

Each of our product candidates will be required to successfully complete clinical trials and other testing to demonstrate the safety and efficacy of the product candidate before it will be approved by the FDA. The completion of these clinical trials and testing will require a significant amount of capital and the hiring of additional personnel.

VenoValve

Background

Chronic venous disease (“CVD”) is the world’s most prevalent chronic disease. CVD is generally classified using a standardized system known as CEAP (clinical, etiological, anatomical, and pathophysiological). The CEAP system consists of seven clinical classifications (C0 to C6) with C5 to C6 being the most severe cases of CVD.

Chronic Venous Insufficiency (“CVI”) is a subset of CVD and is generally used to describe patients with C4 to C6 CVD. CVI is a condition that affects the venous system of the leg causing pain, swelling, edema, skin changes, and ulcerations. The venous vasculature of the human leg includes the superficial venous system, the deep vein system, and the perforator system which connects the superficial veins and deep veins. In order for blood to return to the heart from the foot, ankle, and lower leg, the calf muscle pushes the blood up the veins of the leg and through a series of one-way valves. Each valve is supposed to open as blood passes through, and then close as blood moves up the leg to the next valve. CVI has two primary causes: obstruction, which occurs when a blood clot in the veins of the leg hardens and prevents the free flow of blood; and valvular incompetence which is usually the result of injury to the valves from blood clots, which occurs when the one-way valves in the leg do not close as they should, causing blood to flow in the wrong direction (reflux) and to pool in the lower leg, resulting in increased venous pressure (venous hypertension). CVI can occur in the superficial vein system, the deep vein system, or in both. The initial version of the VenoValve is being developed to treat CVI resulting from valvular incompetence in the deep vein system of the leg.

Estimates indicate that approximately 4.8 million people in the U.S. have C5 to C6 CVI including patients that develop venous leg ulcers from CVI (C6 patients). Over one million new severe cases of CVI occur each year in the U.S., mostly from patients who have experienced a deep vein thrombosis (blood clot). Of those patients suffering from severe CVI, approximately 55% (2.4 million) have reflux in the deep vein system, or both the deep vein system and the superficial vein system. The average patient seeking treatment of a venous ulcer spends as much as $30,000 a year on wound care, and the total direct medical costs from venous ulcer sufferers in the U.S. has been estimated to exceed $38 billion a year. Aside from the direct medical costs, severe CVI sufferers experience a significantly reduced quality of life. Daily activities such as preparing meals, housework, and personal hygiene (washing and bathing) become difficult due to reduced mobility. For many severe CVI sufferers, intense pain, which frequently occurs at night, prevents patients from getting adequate sleep. Severe CVI sufferers are known to miss about 40% more work days than the average worker. A high percentage of venous ulcer patients also experience severe itching, leg swelling, and an odorous discharge. Wound dressing changes which occur several times a week can be extremely painful. In addition, venous ulcers are very difficult to heal, and a significant percentage of venous ulcers remain unhealed for more than a year. Even if healed, recurrence rates for venous ulcers are known to be high (20% to 40%) within the first year.

The Opportunity

The VenoValve is a porcine based valve developed at HJLI to be implanted in the deep vein system of the leg to treat CVI. CVI occurs when the valves in the veins of the leg fail, causing blood to flow backwards and pool in the lower leg and ankle. The backwards flow of the blood is called reflux. Reflux results in increased pressure in the veins of the leg, known as venous hypertension. Venous hypertension leads to swelling, discoloration, severe pain, and open sores called venous ulcers. By reducing reflux, and lowering venous hypertension, the VenoValve has the potential to reduce or eliminate the symptoms of deep venous, severe CVI, including venous leg ulcers. The VenoValve is designed to be surgically implanted into the patient on an outpatient basis via a 5 to 6 inch incision in the upper thigh.

There are presently no FDA approved medical devices to address valvular incompetence, or effective treatments for deep venous CVI. Current treatment options include compression garments, or constant leg elevation. These treatments are generally ineffective for patients with severe deep venous CVI, as they attempt to alleviate the symptoms of CVI without addressing the underlying causes of the disease. In addition, we believe that compliance with compression garments and leg elevation is extremely low, especially among the elderly. Valve transplants from other parts of the body have been attempted, but with very-poor results. Many attempts to create substitute valves have also failed, usually resulting in early thromboses. The premise behind the VenoValve is that by reducing the underlying causes of CVI, reflux and venous hypertension, the debilitating symptoms of CVI will decrease, resulting in improvement in the quality of the lives of CVI sufferers.

There are approximately 2.4 million people in the U.S. that suffer from severe deep venous CVI due to valvular incompetence. The average person with a venous ulcer spends approximately $30,000 per year on wound care, resulting in approximately $38 billion of direct medical costs. For those venous ulcers that do heal, there is a 20% to 40% recurrence rate within one year.

Clinical Status

After consultation with the FDA, as a precursor to the U.S. pivotal trial, we are conducting a small first-in-man study for the VenoValve in Colombia. The first phase of the first-in-man Colombian trial included 10 patients. In addition to providing safety and efficacy data, the purpose of the first-in-man study is to provide proof of concept, and to provide valuable feedback to make any necessary product modifications or adjustments to our surgical implantation procedures for the VenoValve prior to conducting the U.S. pivotal trial. In December of 2018, we received regulatory approval from Instituto Nacional de Vigilancia de Medicamentos y Alimentos (“INVIMA”), the Colombian equivalent of the FDA. On February 19, 2019, we announced that the first VenoValve was successfully implanted in a patient in Bogota. Between April of 2019 and December of 2019, we successfully implanted VenoValves in 9 additional patients, completing the implantations for the first phase of the Colombian first-in-man study. Endpoints for the VenoValve first-in-man study include reflux, measured by doppler, a VCSS score used by the clinician to measure disease severity, and a VAS score used by the patient to measure pain.

On March 4, 2020, Dr. Jorge Hernando Ulloa, the Primary Investigator for the Company’s first-in-man VenoValve study in Colombia, presented updated VenoValve data at the 32nd Annual American Venous Forum meeting on Amelia Island, Florida. Dr. Ulloa’s presentation included data on eight VenoValve patients that are six months post VenoValve surgery (including one patient that is one year post surgery), two patients that are 90 days post-surgery, and one patient that is 60 days post-surgery. For the first patient to receive the VenoValve who is now one year post surgery, Reflux has improved 73% and is now normal, the severity of her CVI has improved 94%, and her pain has improved 75%. This patient showed continued improvement between her six month and one year visits. Because proper directional blood flow in the leg has been restored on a long term basis, the venous system has normalized and there are barely any manifestations of the disease for that patient. Overall, VenoValves have been implanted in 11 patients in Colombia. Across all 11 patients and when comparing pre-operative levels to data recorded at their most recent office visits, Reflux, VCSS Scores, and VAS scores have improved 51%, 61%, and 65% respectively. That includes one patient who is currently occluded, and whose VenoValve is currently not functioning as intended. VenoValve safety incidences have been unchanged since last reported, and include one (1) fluid pocket (which was as aspirated), intolerance from Coumadin anticoagulation therapy, and two (2) minor wound infections (treated with antibiotics).

HJLI has begun preparing for Pre-Investigational Device Exemption (“IDE”) discussions with the FDA and to file its IDE application seeking approval for the U.S. pivotal trial.

Background

Heart disease is the leading cause of death among men and women in the U.S. accounting for about 1 in every 4 deaths. Coronary heart disease is the most common type of heart disease, killing over 370,000 people each year. Coronary heart disease occurs when arteries around the heart become blocked or occluded, in most cases by plaque. Although balloon angioplasty with or without cardiac stents have become the norm if one or two arteries are blocked, coronary artery bypass surgery remains the treatment of choice for patients with multiple blocked arteries. Approximately 200,000 coronary artery bypass graft (“CABG”) surgeries take place each year in the U.S. In the U.S., CABG surgeries are the most commonly performed cardiac procedure. CABG surgeries alone account for 55% of all cardiac surgeries, and CABG surgeries when combined with valve replacement surgeries account for approximately 62% of all cardiac surgeries. The next largest category accounts for 10% of cardiac surgeries. The number of CABG surgeries are expected to increase as the population continues to age. On average, three grafts are used for each CABG surgery.

Although CABG surgeries are invasive, improved surgical techniques over the years have lowered the fatality rate from CABG surgeries to between 1% and 3% prior to discharge from the hospital. Arteries around heart are accessed via an incision along the sternum known as a sternotomy. Once the incision is made, the sternum (chest) is divided (“cracked”) to access the heart and its surrounding arteries.

CABG surgery is relatively safe and effective. In most instances, doctors prefer to use the left internal memory artery (“LIMA”), an artery running inside the ribcage and close to the sternum, to re-vascularize the left side of the heart. Use of the LIMA to revascularize the left descending coronary artery (known as the “widow maker”) has become the gold standard for revascularizing the left side of the heart during CABG surgeries. For the right side of the heart, and where additional grafts are needed on the left side, the current standard of care is to harvest the saphenous vein from the patient’s leg to be dissected into pieces and used as bypass grafts around the heart. Unfortunately, saphenous vein grafts (“SVGs”) are not nearly as effective as the LIMA for revascularizing the heart. In fact, SVGs continue to be the weak link for CABG surgeries.

The saphenous vein harvest procedure is itself invasive. Either a long incision is made along the inner leg of the patient to harvest the vein, or the saphenous vein is extracted endoscopically. Regardless of the type of bypass procedure, bypass graft harvest remains an invasive and complication prone aspect of the CABG procedure. Present standard-of-care complications are described in recent published reports in major medical journals. The percentage of complications from the harvest procedure can be as high as 24%. This is mainly due to non-healing of the saphenous wound or development of infection in the area of the saphenous vein harvest site.

While the LIMA is known for excellent short term and long term patency rates, studies indicate that between 10% and 40% percent of SVGs that are used as conduits for CABG surgeries fail within the first year after the CABG surgery. A significant percentage fail within the first 30 days. At 10 years, the SVGs failure rate can be as high as 75%. When a graft fails, it becomes blocked or occluded, depriving the heart of blood flow. Mortality during the first year after bypass graft failure is very high, between 5% and 9%. For purposes of comparison, a 3% threshold is considered to be a high cardiac risk. In fact, a relatively recent study in Denmark has reported that mortality rates at 8 to 10 years after CABG surgery are as high as 60% to 80%. While a life expectancy of 8 to 10 years following CABG surgery may have been acceptable in the past, expectations have changed and with people now generally living longer, additional focus is now being placed on extending life expectancies following CABG surgeries.

Researchers have determined that there are two main causes of SVGs failure: size mismatch, and a thickening of the interior of the SVGs that begins immediately following the harvest procedure. Size mismatch occurs because the diameter of SVGs is often significantly larger than the diameter of the coronary arteries around the heart. This size mismatch causes flow disturbances, leading to graft thromboses and graft failure. The thickening of the cell walls of SVGs occur when a layer of endothelial cells on the inner surface of the SVGs are disturbed beginning at the harvesting procedure, starting a chain reaction which causes the cells to thicken and the inside of the graft to narrow, resulting in blood clots and graft failure.

The Opportunity

The CoreoGraft is a bovine based off the shelf conduit that could potentially be used to revascularize the heart during CABG surgery, instead of harvesting the saphenous vein from the patient’s leg. In addition to avoiding the invasive and painful SVGs harvest process, HJLI’s CoreoGraft more closely matches the size of the coronary arteries around the heart, eliminating graft failures that occur due to size mismatch. In addition, with no graft harvest needed, the CoreoGraft could also reduce or eliminate the inner thickening that burdens and leads to failure of the SVGs. It has been reported that SVGs have failure rates as high as 10% to 40% within one year of implantation when used as grafts for CABG surgery.

In addition to providing a potential alternative to SVGs, the CoreoGraft could be used when making grafts from the patients’ own arteries and veins is not an option. For example, patients with systemic arterial and vascular disease often do not have suitable vessels to be used as grafts. For other patients, such as women who have undergone radiation treatment for breast cancer and have a higher incidence of heart disease, using the LIMA may not be an option if the LIMA was damaged by radiation during breast cancer treatment. Another example are patients undergoing a second CABG surgery. Due in large part to early SVGs failures, patients may need a second CABG surgery. If the SVGs were used for the first CABG surgery, the patient may have insufficient veins to harvest. While the CoreoGraft may start out as a product for patients with no other options, if the CoreoGraft establishes good short term and long term patency rates, it could become the graft of first choice for all CABG patients in addition to the LIMA.

Approximately 200,000 CABG surgeries are performed each year in the U.S., representing more than 55% of all cardiac surgeries and accounting for between $15 Billion and $25 Billion in annual expenditures. With an average of three grafts used per surgery, we believe the potential U.S. addressable market for the CoreoGraft to be more than $2 Billion per year. There are currently no FDA approved prosthetic grafts for CABG surgeries.

Clinical Status

In January of 2020, we announced the results of a six month, nine sheep, animal feasibility study for the CoreoGraft. Bypasses were accomplished by attaching the CoreoGrafts from the ascending aorta to the left anterior descending artery, and surgeries were preformed both on-pump and off-pump. Partners for the feasibility study included the Texas Heart Institute, and American Preclinical Services.

Test subjects were evaluated via angiograms and flow monitors during the study, and a full pathology examination of the CoreoGrafts and the surrounding tissue was performed post necropsy.

The results from the feasibility study demonstrated that the CoreoGrafts remained patent (open) and fully functional at 30, 90, and 180 day intervals after implantation. In addition, pathology examinations of the grafts and surrounding tissue at the conclusion of the study showed no signs of thrombosis, infection, aneurysmal degeneration, changes in the lumen, or other problems that are known to plague and lead to failure of SVGs.

In addition to exceptional patency, pathology examinations indicated full endothelialization for grafts implanted for 180 days both throughout the CoreoGrafts and into the left anterior descending arteries. Endothelium is a layer of endothelial cells that naturally exist throughout healthy veins and arteries that acts as a barrier between blood and the surrounding tissue, which helps promote the smooth passage of blood. Endothelium are known to produce a variety anti-clotting and other positive characteristics that are essential to healthy veins and arteries. The presence of full endothelialization within the longer term CoreoGrafts indicates that the graft is being accepted and assimilated in a manner similar to natural healthy veins and arteries that exist throughout the vascular system and is an indication of long-term biocompatibility.

Since we believe the results of the CoreoGraft feasibility study were positive, HJLI will now explore the possibility of conducting a first-in-man study outside of the U.S., where the CoreoGrafts would be implanted and tested in humans.

Our Competitive Strengths

We believe we will offer the cardiovascular device market a compelling value proposition with the launch of our two product candidates, if approved, for the following reasons:

Intellectual Property

We possess an extensive proprietary processing and manufacturing methodology specifically applicable to the design, processing, manufacturing and sterilization of biologic devices. This includes FDA compliant quality control and assurance programs, proprietary tissue processing technologies demonstrated to eliminate recipient immune responses, trusted relationship with abattoir suppliers, and a combination of tissue preservation and gamma irradiation that enhances device functions and guarantees sterility. We have filed patent applications for our VenoValve product and Implantable Vein Frame Two product with the U.S. Patent and Trademark Office though there is no assurance that patents will be issued. We also are working on new developments for our CoreoGraft product and expect to be filing for patent protection on that product as well.

Risks Associated with Our Business

Our business is subject to many significant risks, as more fully described in the section entitled “Risk Factors” immediately following this prospectus summary. You should read and carefully consider these risks, together with the risks set forth under the section entitled “Risk Factors” and all of the other information in this prospectus, including the financial statements and the related notes included elsewhere in this prospectus, before deciding whether to invest in our common stock. If any of the risks discussed in this prospectus actually occur, our business, financial condition or operating results could be materially and adversely affected. In particular, our risks include, but are not limited to, the following:

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we remain an emerging growth company, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies. These provisions include, but are not limited to:

In addition, the JOBS Act permits emerging growth companies to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We chose to “opt out” of this provision. We will remain an emerging growth company until the earliest of (i) the end of the fiscal year following the fifth anniversary of the completion of our initial public offering, (ii) the first fiscal year after our annual gross revenues exceed $1.07 billion, (iii) the date on which we have, during the immediately preceding three-year period, issued more than $1.0 billion in non-convertible debt securities or (iv) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeds $700 million as of the end of the second quarter of that fiscal year.

Risks Related to the Coronavirus

The coronavirus pandemic has significantly negatively impacted our business.

The coronavirus pandemic has disrupted the global economy and has negatively impacted large populations including people and businesses that may be directly or indirectly involved with the operation of our company and the manufacturing, development, and testing of our product candidates. The full scope and economic impact of the coronavirus is still unknown and there are many risks from the coronavirus that could generally and negatively impact economies and healthcare providers in the countries where we do business, the medical device industry as a whole, and development stage, pre-revenue companies such as HJLI. At this time, we have identified the following coronavirus related risks that we believe have a greater likelihood of negatively impacting our company specific, including, but not limited to:

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from these sales for general corporate purposes, which includes, without limitation, the continued development of our two lead products, VenoValve and the CoreoGraft, and working capital. The amounts and timing of these expenditures will depend on numerous factors, including the development of our current business initiatives.

PLAN OF DISTRIBUTION

We may sell the securities from time to time to or through underwriters or dealers, through agents, or directly to one or more purchasers. A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, rights to purchase and subscriptions. In addition, the manner in which we may sell some or all of the securities covered by this prospectus includes, without limitation, through:

A prospectus supplement or supplements with respect to each series of securities will describe the terms of the offering, including, to the extent applicable:

The offer and sale of the securities described in this prospectus by us, the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement.

Underwriters and Agents; Direct Sales

If underwriters are used in a sale, they will acquire the offered securities for their own account and may resell the offered securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate.

Unless the prospectus supplement states otherwise, the obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement, other than securities covered by any over-allotment option. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities, and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

Dealers

We may sell the offered securities to dealers as principals. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale.

Institutional Purchasers

We may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or other offering materials, as the case may be, will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

We will enter into such delayed contracts only with institutional purchasers that we approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

Indemnification; Other Relationships

We may provide agents, underwriters, dealers and remarketing firms with indemnification against certain civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.

Market-Making; Stabilization and Other Transactions

There is currently no market for any of the offered securities, other than our common stock, which is quoted on The NASDAQ Capital Market. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We have no current plans for listing of the debt securities, preferred stock, warrants or subscription rights on any securities exchange or quotation system; any such listing with respect to any particular debt securities, preferred stock, warrants or subscription rights will be described in the applicable prospectus supplement or other offering materials, as the case may be.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters or agents that are qualified market makers on The NASDAQ Capital Market may engage in passive market making transactions in our common stock on The NASDAQ Capital Market in accordance with Regulation M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of our common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Fees and Commissions

If 5% or more of the net proceeds of any offering of securities made under this prospectus will be received by a FINRA member participating in the offering or affiliates or associated persons of such FINRA member, the offering will be conducted in accordance with FINRA Rule 5121.

DESCRIPTION OF SECURITIES WE MAY OFFER

This prospectus describes the general terms of our capital stock. The following description is not complete and may not contain all the information you should consider before investing in our capital stock. For a more detailed description of these securities, you should read the applicable provisions of Delaware law and our certificate of incorporation and our bylaws. When we offer to sell a particular series of these securities, we will describe the specific terms of the series in a supplement to this prospectus. Accordingly, for a description of the terms of any series of securities, you must refer to both the prospectus supplement relating to that series and the description of the securities described in this prospectus. To the extent the information contained in the prospectus supplement differs from this summary description, you should rely on the information in the prospectus supplement.

The total number of shares of capital stock we are authorized to issue is 60,000,000 shares, of which (a) 50,000,000 are common stock and (b) 10,000,000 are preferred stock.

We, directly or through agents, dealers or underwriters designated from time to time, may offer, issue and sell, together or separately, up to $75,000,000 in the aggregate of:

We may issue the debt securities as exchangeable for or convertible into shares of common stock, preferred stock or other securities that may be sold by us pursuant to this prospectus or any combination of the foregoing. The preferred stock may also be exchangeable for and/or convertible into shares of common stock, another series of preferred stock or other securities that may be sold by us pursuant to this prospectus or any combination of the foregoing. When a particular series of securities is offered, a supplement to this prospectus will be delivered with this prospectus, which will set forth the terms of the offering and sale of the offered securities.

Common Stock

As of April 6, 2020, there were 19,132,138 shares of common stock issued and outstanding, held of record by approximately 109 stockholders. Subject to preferential rights with respect to any outstanding preferred stock, all outstanding shares of common stock are of the same class and have equal rights and attributes. Under the terms of certificate of incorporation, holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, including the election of directors, and do not have cumulative voting rights. The holders of outstanding shares of common stock are entitled to receive dividends out of assets or funds legally available for the payment of dividends of such times and in such amounts as our board of directors from time to time may determine. Our common stock is not entitled to pre-emptive rights and is not subject to conversion or redemption. Upon liquidation, dissolution or winding up of our company, the assets legally available for distribution to stockholders are distributable ratably among the holders of our common stock after payment of liquidation preferences, if any, on any outstanding payment of other claims of creditors. The rights, preferences and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Our certificate of incorporation empowers our board of directors, without action by our shareholders, to issue up to 10,00,000 shares of preferred stock from time to time in one or more series, which preferred stock may be offered by this prospectus and supplements thereto. As of April 6, 2020, there were no shares of preferred stock designated, issued or outstanding. Our board may fix the rights, preferences, privileges, and restrictions of our authorized but undesignated preferred shares, including:

We will fix the rights, preferences, privileges and restrictions of the preferred stock of each series in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of the related series of preferred stock. This description will include any or all of the following, as required:

If we issue shares of preferred stock under this prospectus, after receipt of payment therefor, the shares will be fully paid and non-assessable.

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of that preferred stock. This right is in addition to any voting rights provided for in the applicable certificate of designation.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of our Company or make removal of management more difficult. Additionally, the issuance of preferred stock could have the effect of decreasing the market price of our common stock.

Warrants

We may issue warrants to purchase our securities or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities that may be sold by us pursuant to this prospectus or any combination of the foregoing and may be attached to, or separate from, such securities. To the extent warrants that we issue are to be publicly-traded, each series of such warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, forms of the warrant and warrant agreement, if any. The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants and a description of the material provisions of the applicable warrant agreement, if any. These terms may include the following:

Exercise of Warrants. Each warrant will entitle the holder of warrants to purchase the amount of securities or other rights, at the exercise price stated or determinable in the prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, if applicable, unexercised warrants will become void. Warrants may be exercised in the manner described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent, if any, or any other office indicated in the prospectus supplement, we will, as soon as possible, forward the securities or other rights that the warrant holder has purchased. If the warrant holder exercises less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants.

Subscription Rights

We may issue rights to purchase our securities. The rights may or may not be transferable by the persons purchasing or receiving the rights. In connection with any rights offering, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such rights offering. In connection with a rights offering to holders of our capital stock a prospectus supplement will be distributed to such holders on the record date for receiving rights in the rights offering set by us.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from a current report on Form 8-K that we file with the SEC, forms of the subscription rights, standby underwriting agreement or other agreements, if any. The prospectus supplement relating to any rights that we offer will include specific terms relating to the offering, including, among other matters:

Each right would entitle the holder of the rights to purchase the principal amount of securities at the exercise price set forth in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will become void.

Holders may exercise rights as described in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent, if any, or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchasable upon exercise of the rights. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as described in the applicable prospectus supplement.

Debt Securities

As used in this prospectus, the term “debt securities” means the debentures, notes, bonds and other evidences of indebtedness that we may issue from time to time. The debt securities will either be senior debt securities, senior subordinated debt or subordinated debt securities. We may also issue convertible debt securities. Debt securities may be issued under an indenture (which we refer to herein as an Indenture), which are contracts entered into between us and a trustee to be named therein. The Indenture has been filed as an exhibit to the registration statement of which this prospectus forms a part. We may issue debt securities and incur additional indebtedness other than through the offering of debt securities pursuant to this prospectus. It is likely that convertible debt securities will not be issued under an Indenture.

The debt securities may be fully and unconditionally guaranteed on a secured or unsecured senior or subordinated basis by one or more guarantors, if any. The obligations of any guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance under applicable law. In the event that any series of debt securities will be subordinated to other indebtedness that we have outstanding or may incur, the terms of the subordination will be set forth in the prospectus supplement relating to the subordinated debt securities.

We may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. Unless indicated in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable Indenture and will be equal in ranking.

Should an Indenture relate to unsecured indebtedness, in the event of a bankruptcy or other liquidation event involving a distribution of assets to satisfy our outstanding indebtedness or an event of default under a loan agreement relating to secured indebtedness of our company or its subsidiaries, the holders of such secured indebtedness, if any, would be entitled to receive payment of principal and interest prior to payments on the unsecured indebtedness issued under an Indenture.

Each prospectus supplement will describe the terms relating to the specific series of debt securities. These terms will include some or all of the following:

Unless otherwise specified in the applicable prospectus supplement, we do not anticipate the debt securities will be listed on any securities exchange. Holders of the debt securities may present registered debt securities for exchange or transfer in the manner described in the applicable prospectus supplement. Except as limited by the applicable Indenture, we will provide these services without charge, other than any tax or other governmental charge payable in connection with the exchange or transfer.

Debt securities may bear interest at a fixed rate or a variable rate as specified in the prospectus supplement. In addition, if specified in the prospectus supplement, we may sell debt securities bearing no interest or interest a t a rate that at the time of issuance is below the prevailing market rate, or at a discount below their stated principal amount. We will describe in the applicable prospectus supplement any special federal income tax considerations applicable to these discounted debt securities.

We may issue debt securities with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by referring to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such debt securities may receive a principal amount on any principal payment date, or interest payments on any interest payment date, that are greater or less than the amount of principal or interest otherwise payable on such dates, depending upon the value on such dates of applicable currency, commodity, equity index or other factors. The applicable prospectus supplement will contain information as to how we will determine the amount of principal or interest payable on any date, as well as the currencies, commodities, equity indices or other factors to which the amount payable on that date relates and certain additional tax considerations.

Units

We may issue units consisting of any combination of the other types of securities offered under this prospectus in one or more series. We may evidence each series of units by unit certificates that we may issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent, if any, may be a bank or trust company that we select. We will indicate the name and address of the unit agent, if any, in the applicable prospectus supplement relating to a particular series of units. Specific unit agreements, if any, will contain additional important terms and provisions. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from a current report that we file with the SEC, the form of unit and the form of each unit agreement, if any, relating to units offered under this prospectus.

If we offer any units, certain terms of that series of units will be described in the applicable prospectus supplement, including, without limitation, the following, as applicable:

Delaware Anti-Takeover Law and Provisions of Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Some provisions of Delaware law, our certificate of incorporation and our bylaws contain provisions that could make the following transactions more difficult: an acquisition of us by means of a tender offer; an acquisition of us by means of a proxy contest or otherwise; or the removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions which provide for payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Delaware Anti-Takeover Law

We are subject to Section 203 of the DGCL. Section 203 generally prohibits a publicly traded corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

Section 203 defines a “business combination” to include:

In general, Section 203 defines an “interested stockholder” as any person that is:

Under specific circumstances, Section 203 makes it more difficult for an “interested stockholder” to effect various business combinations with a corporation for a three-year period, although the stockholders may, by adopting an amendment to the corporation’s certificate of incorporation or bylaws, elect not to be governed by this section, effective 12 months after adoption.

Our certificate of incorporation and bylaws do not exclude us from the restrictions of Section 203. We anticipate that the provisions of Section 203 might encourage companies interested in acquiring us to negotiate in advance with our board of directors since the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder.

Undesignated Preferred Stock

The ability of our board of directors, without action by the stockholders, to issue up to 10,000,000 shares of undesignated preferred stock with voting or other rights or preferences as designated by our board of directors could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company.

Stockholder Meetings

Our certificate of incorporation and bylaws provide that a special meeting of stockholders may be called only by our chairman of the board, chief executive officer or president, or by a resolution adopted by a majority of our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our bylaws establish advance notice procedures with respect to stockholder proposals to be brought before a stockholder meeting and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors.

Elimination of Stockholder Action by Written Consent

Our certificate of incorporation and bylaws eliminate the right of stockholders to act by written consent without a meeting.

Removal of Directors

Our certificate of incorporation provides that no member of our board of directors may be removed from office by our stockholders except for cause and, in addition to any other vote required by law, upon the approval of not less than two-thirds of the total voting power of all of our outstanding voting stock then entitled to vote in the election of directors.

Stockholders Not Entitled to Cumulative Voting

Our certificate of incorporation does not permit stockholders to cumulate their votes in the election of directors. Accordingly, the holders of a majority of the outstanding shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.

Choice of Forum

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the DGCL, our certificate of incorporation or our bylaws; any action to interpret, apply, enforce, or determine the validity of our certificate of incorporation or bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable.

Amendment Provisions

The amendment of any of the above provisions, except for the provision making it possible for our board of directors to issue preferred stock, would require approval by holders of at least two thirds of the total voting power of all of our outstanding voting stock.

The provisions of the DGCL, our amended and restated certificate of incorporation and our amended and restated bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the composition of our board and management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

FORMS OF SECURITIES

Each security may be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

We may issue the securities in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

The specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement or unit agreement.

Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Payments to holders with respect to securities represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of the Company, the trustees, the warrant agents, the unit agents or any other agent of the Company, agent of the trustees, the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other payment or distribution to holders of that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.
