Company Overview
We are a clinical-stage biopharmaceutical company applying a precision medicine approach to the development and commercialization of targeted therapies for cardiovascular diseases. Precision medicine refers to the tailoring of medical treatment to the individual characteristics of patients, using genomic, non-genomic biomarker and other information that extends beyond routine diagnostic categorization. We believe that when implemented correctly precision medicine can enhance therapeutic response, improve patient outcomes, and reduce healthcare costs.
Our lead product candidates are rNAPc2 (AB201) as a potential treatment for diseases caused by ribonucleic acid, or RNA, viruses, initially focusing on COVID-19, the disease syndrome caused by the SARS-CoV-2 virus, and Gencaro™ (bucindolol hydrochloride) for the treatment of atrial fibrillation, or AF, in patients with chronic heart failure, or HF. rNAPc2 targets COVID-19 patients with biomarker evidence of coagulopathy, while Gencaro is being developed for patients who have a genotype that identifies a drug target associated with heightened efficacy.
rNAPc2 (AB201) for treatment of COVID-19
Recombinant Nematode Anticoagulant Protein c2, or rNAPc2 (AB201), is a protein therapeutic in clinical development as a potential treatment for patients with COVID-19. Based on its unique mechanism of action, development history and the clinical evidence from the SARS-CoV-2 pandemic, we believe rNAPc2 has potential to be a beneficial therapy for patients with this serious viral disease. We initiated a Phase 2 clinical trial of rNAPc2 as a potential treatment for patients hospitalized with COVID-19 in the fourth quarter of 2020 and are currently enrolling patients.
Certain patients with severe COVID-19 disease exhibit thrombotic complications and other inflammatory responses suggesting potential dysregulation of the coagulation and immune systems. rNAPc2 is a potent inhibitor of tissue factor, a cellular receptor responsible for initiation of the primary coagulation pathway and appears to be the major activator of the coagulation cascade during viral infection. Tissue factor is also implicated in the immune system inflammatory response to viral infections and in the process of viral dissemination during infection. We believe that evidence from the pandemic implicates tissue factor pathways as an important part of the COVID-19 disease process, and provides a rationale to test rNAPc2 as a potential therapeutic for COVID‑19 for its anticoagulant and potential anti-inflammatory properties.
rNAPc2 was originally developed for potential use as an anticoagulant due to its inhibition of the TF-initiated coagulation process. It was evaluated for the prevention of thrombosis in Phase 1 and Phase 2 clinical studies involving over 800 subjects and demonstrated both safety and efficacy in these studies. rNAPc2 has also been investigated as a potential therapeutic for severe viral infections other than COVID-19. Research has shown that viral infections can provoke dysregulated activation of the TF pathway, resulting in abnormal systemic coagulation and related inflammation, leading to potential organ failure and mortality. For this reason, rNAPc2 was tested as a therapeutic in non-human primates, or NHPs, in studies against lethal doses of the Ebola and Marburg viruses, where it showed evidence of efficacy in the form of mortality reduction, decreases in inflammatory biomarkers and, evidence of reduced disseminated intravascular coagulation, or DIC. DIC is a serious condition that causes abnormal blood clotting throughout the body's blood vessels.
SARS-CoV-2 is a new coronavirus identified in late 2019 that belongs to a family of enveloped RNA viruses that include Middle East Respiratory Syndrome, or MERS, and Severe Acute Respiratory Syndrome (SARS-CoV-1), both of which caused serious human infections of the respiratory system. The disease caused by the SARS-CoV-2 virus has been designated COVID-19. Since this outbreak was first reported in late 2019, there have been over 119 million confirmed cases of COVID-19 and over 2.6 million deaths worldwide attributed to the virus (as of March 2021).
COVID-19 is associated with a high incidence of both arterial and venous coagulation-related adverse events in large and small blood vessels. These include, stroke, myocardial infarction, or MI, (i.e., heart attack) and pulmonary emboli; as well as,
S-2
blockage of the smaller peripheral blood vessels in the fingers/toes (COVID-digit). This syndrome is so frequently observed in COVID-19 that it has received the name of COVID-19 Associated Coagulopathy, or CAC. The underlying pathology of CAC is believed to result from thrombo-inflammatory processes triggered by the viral infection. A commonly used biomarker for assessing the presence of abnormal coagulation is a D-dimer test, which is elevated (greater than 0.5) in nearly 70% of hospitalized COVID-19 patients and is associated with adverse clinical outcomes. Some researchers believe that this and other evidence points to dysregulation of TF pathways in COVID-19 patients that result in the development of thrombotic complications.
rNAPc2 has shown potential in addressing the coagulation disorder caused by severe viral infections. In preliminary, non-human studies in NHPs against lethal doses of the Ebola and Marburg virus, rNAPc2 lowered D-dimer levels, reduced mortality and exhibited anti-inflammatory effects. We believe more recent research supports our belief that rNAPc2 has the ability to inhibit the activity of TF in multiple processes that contribute to severe viral disease. Taken together, we believe this evidence suggests that rNAPc2 may have therapeutic benefits for patients with serious COVID-19 infections and the accompanying high risk of thrombosis. To our knowledge, rNAPc2 is the only NME anticoagulant, and the only tissue factor inhibitor, currently under evaluation for COVID-19.
As a therapeutic aimed at a host response to a disease syndrome, we believe rNAPc2 potentially could be used in combination with other antiviral drugs. We believe its potential efficacy is not linked to a specific viral genome and may not be diminished by genetic drift or the development of new strains of the SARS-CoV-2 virus. As a therapeutic addressing a disease, we believe rNAPc2 may have broad spectrum potential against multiple pathogens that have disease elements in common with COVID‑19, such as other coronaviruses and other RNA viruses. Therefore, we believe that rNAPc2 has therapeutic potential for future viral outbreaks beyond the current pandemic.
rNAPc2 is a single-chain, 85 amino acid, recombinant protein administered subcutaneously, that has previously been evaluated under three FDA Investigational New Drug, or IND, applications in six Phase 1 and three Phase 2 clinical studies in the United States and Europe. These clinical trials primarily examined the safety, dosing and anticoagulation effects of rNAPc2 in patients with acute coronary syndromes, in patients undergoing knee replacement surgery and in patients undergoing percutaneous coronary interventions. In these trials, involving more than 800 human patients with over 700 exposed to drug, rNAPc2 was generally well-tolerated with a safety profile comparable to commercially available anticoagulants. rNAPc2 is manufactured in an engineered yeast strain by an established methodology following current Good Manufacturing Practices, or cGMP, and we believe this process can be readily scaled to commercial quantities. FDA granted rNAPc2 Orphan Drug Designation status in 2014 for the treatment of viral hemorrhagic fever post-exposure to Ebola virus, but human clinical trials were not conducted.
In October 2020, FDA approved the IND application for rNAPc2 as a potential treatment for patients hospitalized with COVID-19 and it received a Fast-Track designation in November 2020. We initiated the Phase 2b clinical trial of rNAPc2 (AB201), ASPEN-COVID-19, in patients hospitalized with COVID-19 in the fourth quarter of 2020. We anticipate announcing topline data from this approximately 100 patient Phase 2b clinical trial in the third quarter of 2021.
We are evaluating rNAPc2 as a treatment for patients hospitalized with COVID-19 who are at high risk for thrombotic complications, as indicated by elevated D-dimer levels. The Phase 2b clinical trial is designed to be a randomized comparison of two-dose regimens of rNAPc2 versus heparin prescribed per local standard of care. The primary endpoint of the clinical trial is the change in D-dimer level from baseline to Day 8. If Phase 2b results indicate a favorable effect on D-dimer levels and safety is confirmed, following FDA review of the data and identification of the proposed Phase 3 rNAPc2 dose, we anticipate that clinical investigative sites will begin enrolling patients in a planned Phase 3 clinical trial. The primary endpoint of Phase 3 is planned to be clinical recovery as measured by the Adaptive COVID-19 Treatment Trial ordinal scale, with secondary endpoints that include D-dimer levels and the number of thrombotic events. We believe the Phase 3 clinical trial will be event driven, with an estimated requirement of 450 patients. We believe that favorable results from this Phase 2b/3 clinical trial program could support use of rNAPc2 in COVID-19 patients, given its potential efficacy both as an anticoagulant and an anti-viral agent that we believe counters the dysregulatory immune response and improves clinical recovery.
The clinical trial is being managed in collaboration with the Colorado Prevention Center, or CPC, the University of Colorado's Academic Research Organization with extensive experience in managing vascular and anticoagulation clinical trials.
We have financed the development of rNAPc2 through public equity sales. Our rNAPc2 development plans, including the timeline, depend on our ability to enroll patients during the COVID-19 pandemic, the results of our Phase 2b clinical trial, FDA guidance, and availability of drug product, all of which are currently uncertain.
We own the clinical development program of rNAPc2, including Phase 2 clinical trials. If rNAPc2 is successfully developed, we believe it will have intellectual property protection, including 12 years of market exclusivity as an innovative biologic
S-3
product under FDA law in the United States, 10 years data protection exclusivity in the European Union, or EU, and potentially patent protection in addition to this. We plan to pursue strategic co-development and partnering opportunities for rNAPc2 development and commercialization.
Gencaro™ (bucindolol hydrochloride) for Atrial Fibrillation
Gencaro™ (bucindolol hydrochloride) is a pharmacogenetically-targeted beta-adrenergic receptor antagonist with mild vasodilator properties that we are developing for the treatment of atrial fibrillation in patients with heart failure. We believe the pharmacology of Gencaro is unique and its efficacy can be enhanced by prescribing it to patients with a common genotypic variant that is present in approximately 50% of the North American and European general populations. This gene can be detected with a simple genetic test.
We are developing Gencaro to treat atrial fibrillation, or AF, in patients with chronic heart failure, or HF. AF is the most common form of cardiac arrhythmia, a disruption of the heart’s normal rhythm or rate. HF is a chronic condition in which the heart is unable to pump enough blood to meet the body’s needs. AF and HF commonly occur together. In HF patients, the development of AF leads to worsening symptoms, and increased risk of hospitalization and death. Current treatment options for AF in HF patients are limited, and can be invasive, costly and dangerous.
Our development plan for Gencaro focuses on the treatment of AF in patients with higher ejection fraction HF, those who have an ejection fraction, or EF, of 40% and higher who also have the genotype we believe is optimal for Gencaro efficacy. This population of HF encompasses more than half of all HF patients in the United States and Europe. There are currently few approved or effective drug therapies to treat AF or HF in this patient population.
Our development plan for Gencaro is based on our recent analysis of the Phase 2b clinical trial of Gencaro for the prevention of AF in HF patients, known as GENETIC-AF. This analysis showed novel results for Gencaro in patients in the clinical trial with EF’s of 40% and higher. We are planning a new design for a Phase 3 pivotal clinical trial of Gencaro based on this analysis that addresses what we believe are important clinical assessments, including the total amount of time that a patient experiences AF, known as AF burden, maintenance of normal sinus rhythm, rhythm control interventions such as electrical cardioversion, catheter ablation and use of anti-arrhythmic drugs and drug-related complications such as bradycardia. Based on these analyses, we were issued a United States patent in February 2021 for the use of Gencaro in this patient population. We believe this patent will substantially extend the patent protection for our planned development of Gencaro into 2039. We are seeking similar patent protection in other countries.
We currently have an agreement with the FDA, known as a Special Protocol Assessment, or SPA, for the requirements of a Gencaro Phase 3 clinical trial, PRECISION-AF, that would support approval of Gencaro if successful. Based on our recent analyses of the GENETIC-AF data, we may alter the design of PRECISION-AF to focus on endpoints that are not covered in the SPA agreement.
We believe that patients with HF and AF represent a major unmet medical need, and this need is most pronounced in patients with EF values of 40% and above. This EF range constitutes more than half of all chronic HF in the United States and Europe, as well as in Japan and China, and there are currently few approved, effective or guideline-recommended therapies for these patients to treat either their AF or HF. AF is a very common complication in these patients, with estimates of AF incidence ranging from 40% to 60%. Beta-blockers approved for HF are commonly used off-label to control heart rate in these patients, but they are not considered effective in preventing AF and none are approved for patients with EF ≥ 40%. Other anti-arrhythmic drugs approved for the treatment of AF have adverse side effects and in HF patients are either contraindicated or have label warnings for use due to an increased risk of mortality. Interventional procedures for AF, such as catheter ablation and electrical cardioversion, are invasive, expensive, and often temporary; these interventions also typically require the continued use of beta blockers and other anti-arrhythmic drugs post-intervention.
S-4
We believe that Gencaro, if approved, may be a safe and more effective therapy for the treatment of higher ejection fraction HF patients with AF. We believe there are several potentially important attributes that would differentiate Gencaro from existing therapies, including:
| • | More effective rhythm control compared to the current standard of care; |
| • | Reduction in the need for catheter ablation, electrical cardioversion, or toxic anti-arrhythmic drugs; |
| • | Maintenance of rhythm control after a successful AF catheter ablation; |
| • | Effective rate control with lower risk of treatment-limiting bradycardia; |
| • | Reduction in symptoms and improvement in quality of life; |
| • | Reduced health care burden; |
| • | Foundational beta-blocker benefits for HF and unique evidence of efficacy in HF patients with AF; |
| • | One of the only drug therapies approved and shown effective for AF in HF patients with EF ≥ 40%, and the only one in its drug class. |
We have an international patent portfolio for Gencaro in the United States, the EU, and other major markets, as well as new chemical entity status, including a new patent that we believe will give us a strong intellectual property position to at least approximately 2039 in the United States; we have filed applications similar to this new patent in international territories. We have developed a laboratory platform for the diagnostic test that would be used to prescribe Gencaro; this platform was approved by FDA for use in the Phase 2B clinical trial. We retain all rights to this test platform; we expect to use it in future clinical trials, and we believe it could be one of multiple diagnostic platforms used for commercialization.
To support the continued development of rNAPc2 and Gencaro, we will need additional financing to fully fund the planned clinical trials, and our general and administrative costs through the clinical trials’ projected completion and potential commercialization. Considering the substantial time and costs associated with the development of rNAPc2 and Gencaro and the risk that we may be unable to raise a significant amount of capital on acceptable terms, we are also pursuing co-development and commercialization partnering opportunities with large pharmaceutical and/or specialty pharmaceutical companies and may pursue a strategic combination or other strategic transactions. If we are unable to obtain sufficient financing or are unable to complete a strategic transaction, we may discontinue our development activities on rNAPc2 or Gencaro or discontinue our operations.

Risks Associated with Our Business
Our business is subject to numerous risks and uncertainties, including those highlighted in the section titled “Risk Factors” immediately following this prospectus supplement summary and those described under similar headings in the documents incorporated by reference into this prospectus supplement and accompanying prospectus. You should read these risks before you invest in our securities. We may be unable, for many reasons, including those that are beyond our control, to implement our business strategy. In particular, some of our risks include:
| • |
| If we are not able to successfully develop, obtain FDA approval for, and provide for the commercialization of rNAPc2 Gencaro in a timely manner, we may not be able to continue our business operations. |
| • |
| We will need to raise substantial additional funds through public or private equity or debt transactions and/or complete one or more strategic transactions, to continue development of rNAPc2, Gencaro or any of our other product candidates. If we are unable to raise such financing or complete such a transaction, we may not be able to continue operations.
|
| • |
| Our audited financial statements for the fiscal year ended December 31, 2020 were prepared assuming that we will continue as a going concern. Our management has concluded that due to our need for additional capital, and the uncertainties surrounding our ability to raise such funding, there may be uncertainty about our ability to continue as a going concern in future years. |
| • |
| Our business could be adversely affected by the effects of health epidemics, including the ongoing COVID-19 global pandemic, in regions where we or third parties on which we rely may have clinical trial sites or other business operations. We anticipate having clinical trial sites in countries that have been directly affected by COVID-19 and depend on third party manufacturing operations for various stages of our supply chain. |
| • |
| We have received an SPA agreement from the FDA relating to our planned Phase 3 program for Gencaro. This SPA agreement does not guarantee approval of Gencaro or any other particular outcome from regulatory review. |
| • |
| If we are not able to maintain the requirements for listing on the Nasdaq Capital Market, we could be delisted, which could have a material adverse effect on our ability to raise additional funds as well as the price and liquidity of our common stock. |
| • |
| rNAPc2 may not yield results that will enable us to further develop it as a therapy and obtain regulatory approvals necessary to be used as a drug.
|
| • |
| If we encounter difficulties enrolling patients in our clinical trial of rNAPc2, any potential enrollment milestones or potential regulatory approvals could be delayed or otherwise adversely affected. |
| • |
| Any future clinical trial for Gencaro will require the use of a third-party diagnostic services provider to administer a genetic test needed to identify the patient receptor genotypes of clinical trial participants, and as a result, we will be unable to directly control the timing, conduct and expense of the genetic test. |
| • |
| We will need to establish a collaborative arrangement with a third-party diagnostics services provider to obtain marketing clearance or approval of the companion genetic test. There is no guarantee that the FDA will grant timely clearance or approval of the genetic test, if at all, and failure to obtain such timely clearance or approval would adversely affect our ability to market Gencaro. |
| • |
| Our product candidates are subject to extensive regulation, which can be costly and time-consuming, and unsuccessful or delayed regulatory approvals could increase our future development costs or impair our future revenue. |
| • |
| If approved by the FDA, rNAPc2 or Gencaro will be entering a competitive marketplace and may not succeed. |

Assuming that an aggregate of 13,297,872 shares of our common stock are sold at a price of $3.76 per share, the last reported sale price of our common stock on the Exchange on April 1, 2021, for aggregate gross proceeds of $50,000,000, and after deducting commissions and estimated offering expenses payable by us, you would experience immediate dilution of $(0.40) per share, representing the difference between our as adjusted net tangible book value per share as December 31, 2020 after giving effect to this offering and the assumed offering price. If we were to sell shares of our common stock in this offering at a price per share greater than our net tangible book value, it would result in dilution of your investment. The exercise of outstanding stock options and warrants or the settlement of outstanding restricted stock units would result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed illustration of the dilution you may incur if you participate in this offering. Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant. Purchasers of the shares we sell, as well as our existing shareholders, will experience significant dilution if we sell shares at prices significantly below the price at which they invested.
Future sales or the possibility of future sales of our common stock may depress the market price of our common stock.
Sales in the public market of substantial amounts of our common stock could depress prevailing market prices of our common stock. As of December 31, 2020, approximately 9.5 million shares of common stock were outstanding, and all of these shares are freely transferable without restriction or further registration under the Securities Act, except for shares held by our directors, officers and other affiliates and unregistered shares held by non-affiliates. The sale of these additional shares, or the perception that such sales may occur, could depress the market price of our common stock.
As of December 31, 2020, approximately 133,000 shares of our common stock were issuable upon the exercise of outstanding warrants. Once a warrant is exercised, if the shares of our common stock issued upon the exercise of any such warrant are not available for sale in the open market without further registration under the Securities Act, then the holder can arrange for the resale of shares either by invoking any applicable registration rights, causing the shares to be registered under the Securities Act and thus freely transferable, or by relying on an exemption to the Securities Act.
As of December 31, 2020, there were approximately 531,000 shares of our common stock which may be issued upon the exercise of outstanding stock options and the settlement of restricted stock units, and we anticipate that we will continue to issue stock option and restricted stock unit awards to our employees and consultants in the fiscal year ended December 31, 2021 and thereafter. If and when these options are exercised and these restricted stock units are vested, such shares will be available for sale in the open market without further registration under the Securities Act. The existence of these outstanding options and restricted stock units may negatively affect our ability to complete future equity financings at acceptable prices and on acceptable terms. The exercise of those options and settlement of the restricted stock units, and the prompt resale of shares of our common stock received, may also result in downward pressure on the price of our common stock.
S-9
In the absence of a significant strategic transaction, we will need to raise significant additional capital to finance the research, development and commercialization of rNAPc2and Gencaro. If future securities offerings occur, they would dilute our current stockholders’ equity interests and could reduce the market price of our common stock.
We have implemented anti-takeover provisions that could discourage, prevent or delay a takeover, even if the acquisition would be beneficial to our stockholders.
Provisions of our certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders. These provisions:
| • |
| establish a classified board of directors so that not all members of our board may be elected at one time; |
| • |
| authorize the issuance of up to approximately 5 million additional shares of preferred stock that could be issued by our board of directors to increase the number of outstanding shares and hinder a takeover attempt; |
| • |
| limit who may call a special meeting of stockholders; |
| • |
| prohibit stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders; and |
| • |
| establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon at a stockholder meeting. |
Specifically, our certificate of incorporation provides that all stockholder action must be effected at a duly called meeting and not by a written consent. The bylaws provide, however, that our stockholders may call a special meeting of stockholders only upon a request of stockholders owning at least 50% of our outstanding common stock. These provisions of our certificate of incorporation and bylaws could discourage potential acquisition proposals and could delay or prevent a change in control. We designed these provisions to reduce our vulnerability to unsolicited acquisition proposals and to discourage certain tactics that may be used in proxy fights. These provisions, however, could also have the effect of discouraging others from making tender offers for our shares. As a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.
We are permitted to issue shares of our preferred stock without stockholder approval upon such terms as our board of directors determines. Therefore, the rights of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of our preferred stock that may be issued in the future. In addition, the issuance of preferred stock could have a dilutive effect on the holdings of our current stockholders.
We are subject to the Delaware anti-takeover laws regulating corporate takeovers. These anti-takeover laws prevent a Delaware corporation from engaging in a merger or sale of more than 10% of its assets with any stockholder, including all affiliates and associates of the stockholder, who owns 15% or more of the corporation’s outstanding voting stock, for three years following the date that the stockholder acquired 15% or more of the corporation’s stock unless:
| • |
| the board of directors approved the transaction where the stockholder acquired 15% or more of the corporation’s stock; |
| • |
| after the transaction in which the stockholder acquired 15% or more of the corporation’s stock, the stockholder owned at least 85% of the corporation’s outstanding voting stock, excluding shares owned by directors, officers and employee stock plans in which employee participants do not have the right to determine confidentially whether shares held under the plan will be tendered in a tender or exchange offer; or |
| • |
| on or after this date, the merger or sale is approved by the board of directors and the holders of at least two-thirds of the outstanding voting stock that is not owned by the stockholder. |
The provisions of our governing documents and current Delaware law may collectively:
| • |
| lengthen the time required for a person or entity to acquire control of us through a proxy contest for the election of a majority of our board of directors; |
| • |
| discourage bids for our common stock at a premium over market price; and |
| • |
| generally deter efforts to obtain control of us. |
S-10
Terms of subsequent financings may adversely impact our stockholders.
To finance our future business plans and working capital needs, including to complete our ongoing clinical trial of rNAPc2 (AB201), we will have to raise funds through the issuance of equity or debt securities in addition to sales in this offering. Depending on the type and the terms of any financing we pursue, stockholders’ rights and the value of their investment in our common stock and the warrants could be reduced. A financing could involve one or more types of securities including common stock, convertible debt or warrants to acquire common stock. These securities could be issued at or below the then prevailing market price for our common stock. In addition, if we issue secured debt securities, the holders of the debt would have a claim to our assets that would be senior to the rights of stockholders until the debt is paid. Interest on these debt securities would increase costs and negatively impact operating results. If the issuance of new securities results in diminished rights to holders of our common stock, the market price of our common stock could be negatively impacted and the value of the warrants could decline.
Our management might apply the net proceeds from this offering in ways with which you do not agree and in ways that may impair the value of your investment.
We currently intend to use the net proceeds from the sale of the securities under this prospectus for our clinical trial of rNAPc2 and for working capital and general corporate purposes, including research and development expenses and general and administrative expenses. Our management has broad discretion as to the use of these proceeds and you will be relying on the judgment of our management regarding the application of these proceeds. We might apply these proceeds in ways with which you do not agree, or in ways that do not yield a favorable return. If our management applies these proceeds in a manner that does not yield a significant return, if any, on our investment of these net proceeds, it could compromise our ability to pursue our growth strategy and adversely affect the market price of our common stock.

Pursuant to the terms of the Sales Agreement, we may issue and sell shares of our common stock from time to time through or to JonesTrading, acting as sales agent or principal. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the Sales Agreement with JonesTrading as a source of financing.
We intend to use the net proceeds from the sale of the common stock under this prospectus supplement and accompanying prospectus for working capital and general corporate purposes, including research and development expenses and general and administrative expenses. We believe the amount raised in this offering will allow us to fund our clinical trial, including costs for clinical study drug, site selection, and contract research organization, or CRO, selection and patient enrollment. We may also use a portion of the net proceeds and our existing cash and cash equivalents to in-license, acquire, or invest in businesses, technologies, products or assets; however, we have no current plans, commitments or obligations to do so.
Our expected use of proceeds from this offering described above represents our current intentions based on our present plans and business condition. As of the date of this prospectus, we cannot predict with certainty all of the particular uses for the proceeds to be received upon the closing of this offering or the actual amounts that we will spend on the uses set forth above.
S-14
Our net tangible book value as of December 31, 2020 was approximately $46.5 million, or $4.87 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of December 31, 2020. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.
After giving effect to the sale of 13,297,872 shares of our common stock in this offering at an assumed offering price of $3.76 per share, the last reported sale price of our common stock on the Exchange on April 1, 2021, and after deducting estimated offering commissions and offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2020 would have been approximately $95.0 million, or $4.16 per share. This represents a $0.71 decrease in our net tangible book value per share, and immediate dilution of $(0.40) per share to investors purchasing our common stock in this offering at the assumed public offering price. The following table illustrates this dilution on a per share basis:
Assumed public offering price per share |

The above discussion and table are based on 9,548,150 shares of our common stock outstanding as of December 31, 2020 and excludes:
| • |
| 531,238 shares of our common stock issuable upon the exercise of stock options outstanding as of December 31, 2020, at a weighted average exercise price of $8.71 per share; |
| • |
| 133,401 shares of our common stock issuable upon exercise of warrants outstanding as of December 31, 2020, at a weighted average exercise price of $109.80 per share; |
| • |
| 636,347 shares of our common stock reserved for issuance under our equity incentive and non-employee director stock award plans as of December 31, 2020; and
|
| • |
| 4,861,993 shares of our common stock issued pursuant to “at the market offerings” from January 1, 2021 through February 22, 2021. |
The table above assumes for illustrative purposes that an aggregate of 13,297,872 shares of our common stock are sold during the term of the Sales Agreement with JonesTrading at a price of $3.76 per share, the last reported sale price of our common stock on the Exchange on April 1, 2021, for aggregate gross proceeds of $50,000,000. The shares subject to the Sales Agreement with JonesTrading are being sold from time to time at various prices. An increase of $1.00 per share in the price at which the shares are sold from the assumed offering price of $3.76 per share shown in the table above, assuming all of our common stock in the aggregate amount of $50,000,000 during the term of the Sales Agreement with JonesTrading is sold at that price, would increase our adjusted net tangible book value per share after the offering to $4.74 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $0.02 per share, after deducting commissions and estimated aggregate offering expenses payable by us. A decrease of $1.00 per share in the price at which the shares are sold from the assumed offering price of $3.76 per share shown in the table above, assuming all of our common stock in the aggregate amount of $50,000,000 during the term of the Sales Agreement with JonesTrading is sold at that price, would decrease our adjusted net tangible book value per share after the offering to $3.43 per share and would decrease the dilution in net tangible book value per share to new investors in this offering to $(0.67) per share, after deducting commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only.
S-15
To the extent that options or warrants outstanding as of December 31, 2020 have been or may be exercised or other shares issued, investors purchasing our common stock in this offering may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.
S-16
On April 6, 2021, we entered into an amendment, or the Amendment No. 1, to our Capital on Demand™ Sales Agreement, dated July 22, 2020 with JonesTrading Institutional Services LLC, or JonesTrading, or the Original Agreement and, together with the Amendment No. 1, the Sales Agreement, relating to shares of our common stock, $0.001 par value per share, offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the Sales Agreement, we may offer and sell shares of our common stock having an aggregate offering price of up to $50,000,000 from time to time through or to JonesTrading, acting as our agent or principal. Sales of our common stock, if any, under this prospectus supplement and accompanying prospectus may be made in sales deemed to be “at the market offerings” as defined in Rule 415 promulgated under the Securities Act. The Original Agreement has previously been filed as an exhibit to our Current Report on Form 8-K filed with the SEC on July 22, 2020.
Each time we wish to issue and sell common stock, we will notify JonesTrading of the number of shares to be issued, the dates on which such sales are anticipated to be made, any minimum price below which sales may not be made and other sales parameters as we deem appropriate. Once we have so instructed JonesTrading, unless JonesTrading declines to accept the terms of the notice, JonesTrading has agreed, subject to the terms and conditions of the Sales Agreement, 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. We may instruct JonesTrading not to sell shares of common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or JonesTrading may suspend the offering of shares of common stock being made through JonesTrading under the Sales Agreement upon proper notice to the other party.
We will pay JonesTrading commissions for its services in acting as agent in the sale of our common stock. JonesTrading will be entitled to compensation at a commission rate equal to 3.0% of the aggregate gross sales price of the shares sold. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We estimate that the total expenses for this offering (inclusive of expenses paid in connection with entering into the Sales Agreement), excluding compensation and reimbursements payable to JonesTrading under the terms of the Sales Agreement, will be approximately $65,000.
Settlement for sales of common stock will occur on the second business day following the date on which any sales are made or such earlier day as is industry practice for regular-way trading, or on some other date that is agreed upon by us and JonesTrading in connection with a particular transaction, in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.
In connection with the sale of the common stock on our behalf, JonesTrading will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of JonesTrading will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to JonesTrading against certain civil liabilities, including liabilities under the Securities Act.
Our common stock is listed on the Exchange and trades under the symbol “ABIO.” The transfer agent of our common stock is Computershare Trust Company, N.A.
JonesTrading and/or its affiliates have in the past and may in the future provide various investment banking and other financial services for us for which services they may in the future receive customary fees.

Overview
We are a clinical-stage biopharmaceutical company applying a precision medicine approach to the development and commercialization of targeted therapies for cardiovascular diseases. Precision medicine refers to the tailoring of medical treatment to the individual characteristics of patients, using genomic, non-genomic biomarker and other information that extends beyond routine diagnostic categorization. We believe that when implemented correctly precision medicine can enhance therapeutic response, improve patient outcomes, and reduce healthcare costs.
Our lead product candidates are rNAPc2 (AB201) as a potential treatment for diseases caused by ribonucleic acid, or RNA, viruses, initially focusing on COVID-19, the disease syndrome caused by the SARS-CoV-2 virus, and Gencaro™ (bucindolol hydrochloride) for the treatment of atrial fibrillation, or AF, in patients with chronic heart failure, or HF. rNAPc2 targets COVID-19 patients with biomarker evidence of coagulopathy, while Gencaro is being developed for patients who have a genotype that identifies a drug target associated with heightened efficacy.
rNAPc2 (AB201) for treatment of COVID-19
Recombinant Nematode Anticoagulant Protein c2, or rNAPc2 (AB201), is a protein therapeutic in clinical development as a potential treatment for patients with COVID-19. Based on its unique mechanism of action, development history and the clinical evidence from the SARS-CoV-2 pandemic, we believe rNAPc2 has potential to be a beneficial therapy for patients with this serious viral disease. We initiated a Phase 2 clinical trial of rNAPc2 as a potential treatment for patients hospitalized with COVID-19 in the fourth quarter of 2020 and are currently enrolling patients.
Certain patients with severe COVID-19 disease exhibit thrombotic complications and other inflammatory responses suggesting potential dysregulation of the coagulation and immune systems. rNAPc2 is a potent inhibitor of tissue factor, a cellular receptor responsible for initiation of the primary coagulation pathway and appears to be the major activator of the coagulation cascade during viral infection. Tissue factor is also implicated in the immune system inflammatory response to viral infections and in the process of viral dissemination during infection. We believe that evidence from the pandemic implicates tissue factor pathways as an important part of the COVID-19 disease process, and provides a rationale to test rNAPc2 as a potential therapeutic for COVID‑19 for its anticoagulant and potential anti-inflammatory properties.
rNAPc2 was originally developed for potential use as an anticoagulant due to its inhibition of the TF-initiated coagulation process. It was evaluated for the prevention of thrombosis in Phase 1 and Phase 2 clinical studies involving over 800 subjects and demonstrated both safety and efficacy in these studies. rNAPc2 has also been investigated as a potential therapeutic for severe viral infections other than COVID-19. Research has shown that viral infections can provoke dysregulated activation of the TF pathway, resulting in abnormal systemic coagulation and related inflammation, leading to potential organ failure and mortality. For this reason, rNAPc2 was tested as a therapeutic in non-human primates, or NHPs, in studies against lethal doses of the Ebola and Marburg viruses, where it showed evidence of efficacy in the form of mortality reduction, decreases in inflammatory biomarkers and, evidence of reduced disseminated intravascular coagulation, or DIC. DIC is a serious condition that causes abnormal blood clotting throughout the body's blood vessels.
4.
SARS-CoV-2 is a new coronavirus identified in late 2019 that belongs to a family of enveloped RNA viruses that include Middle East Respiratory Syndrome, or MERS, and Severe Acute Respiratory Syndrome (SARS-CoV-1), both of which caused serious human infections of the respiratory system. The disease caused by the SARS-CoV-2 virus has been designated COVID-19. Since this outbreak was first reported in late 2019, there have been over 119 million confirmed cases of COVID-19 and over 2.6 million deaths worldwide attributed to the virus (as of March 2021).
COVID-19 is associated with a high incidence of both arterial and venous coagulation-related adverse events in large and small blood vessels. These include, stroke, myocardial infarction, or MI, (i.e., heart attack) and pulmonary emboli; as well as, blockage of the smaller peripheral blood vessels in the fingers/toes (COVID-digit). This syndrome is so frequently observed in COVID-19 that it has received the name of COVID-19 Associated Coagulopathy, or CAC. The underlying pathology of CAC is believed to result from thrombo-inflammatory processes triggered by the viral infection. A commonly used biomarker for assessing the presence of abnormal coagulation is a D-dimer test, which is elevated (greater than 0.5) in nearly 70% of hospitalized COVID-19 patients and is associated with adverse clinical outcomes. Some researchers believe that this and other evidence points to dysregulation of TF pathways in COVID-19 patients that result in the development of thrombotic complications.
rNAPc2 has shown potential in addressing the coagulation disorder caused by severe viral infections. In preliminary, non-human studies in NHPs against lethal doses of the Ebola and Marburg virus, rNAPc2 lowered D-dimer levels, reduced mortality and exhibited anti-inflammatory effects. We believe more recent research supports our belief that rNAPc2 has the ability to inhibit the activity of TF in multiple processes that contribute to severe viral disease. Taken together, we believe this evidence suggests that rNAPc2 may have therapeutic benefits for patients with serious COVID-19 infections and the accompanying high risk of thrombosis. To our knowledge, rNAPc2 is the only NME anticoagulant, and the only tissue factor inhibitor, currently under evaluation for COVID-19.
As a therapeutic aimed at a host response to a disease syndrome, we believe rNAPc2 potentially could be used in combination with other antiviral drugs. We believe its potential efficacy is not linked to a specific viral genome and may not be diminished by genetic drift or the development of new strains of the SARS-CoV-2 virus. As a therapeutic addressing a disease, we believe rNAPc2 may have broad spectrum potential against multiple pathogens that have disease elements in common with COVID‑19, such as other coronaviruses and other RNA viruses. Therefore, we believe that rNAPc2 has therapeutic potential for future viral outbreaks beyond the current pandemic.
rNAPc2 is a single-chain, 85 amino acid, recombinant protein administered subcutaneously, that has previously been evaluated under three FDA Investigational New Drug, or IND, applications in six Phase 1 and three Phase 2 clinical studies in the United States and Europe. These clinical trials primarily examined the safety, dosing and anticoagulation effects of rNAPc2 in patients with acute coronary syndromes, in patients undergoing knee replacement surgery and in patients undergoing percutaneous coronary interventions. In these trials, involving more than 800 human patients with over 700 exposed to drug, rNAPc2 was generally well-tolerated with a safety profile comparable to commercially available anticoagulants. rNAPc2 is manufactured in an engineered yeast strain by an established methodology following current Good Manufacturing Practices, or cGMP, and we believe this process can be readily scaled to commercial quantities. FDA granted rNAPc2 Orphan Drug Designation status in 2014 for the treatment of viral hemorrhagic fever post-exposure to Ebola virus, but human clinical trials were not conducted.
In October 2020, FDA approved the IND application for rNAPc2 as a potential treatment for patients hospitalized with COVID-19 and it received a Fast-Track designation in November 2020. We initiated the Phase 2b clinical trial of rNAPc2 (AB201), ASPEN-COVID-19, in patients hospitalized with COVID-19 in the fourth quarter of 2020. We anticipate announcing topline data from this approximately 100 patient Phase 2b clinical trial in the third quarter of 2021.
5.
We are evaluating rNAPc2 as a treatment for patients hospitalized with COVID-19 who are at high risk for thrombotic complications, as indicated by elevated D-dimer levels. The Phase 2b clinical trial is designed to be a randomized comparison of two-dose regimens of rNAPc2 versus heparin prescribed per local standard of care. The primary endpoint of the clinical trial is the change in D-dimer level from baseline to Day 8. If Phase 2b results indicate a favorable effect on D-dimer levels and safety is confirmed, following FDA review of the data and identification of the proposed Phase 3 rNAPc2 dose, we anticipate that clinical investigative sites will begin enrolling patients in a planned Phase 3 clinical trial. The primary endpoint of Phase 3 is planned to be clinical recovery as measured by the Adaptive COVID-19 Treatment Trial ordinal scale, with secondary endpoints that include D-dimer levels and the number of thrombotic events. We believe the Phase 3 clinical trial will be event driven, with an estimated requirement of 450 patients. We believe that favorable results from this Phase 2b/3 clinical trial program could support use of rNAPc2 in COVID-19 patients, given its potential efficacy both as an anticoagulant and an anti-viral agent that we believe counters the dysregulatory immune response and improves clinical recovery.
The clinical trial is being managed in collaboration with the Colorado Prevention Center, or CPC, the University of Colorado's Academic Research Organization with extensive experience in managing vascular and anticoagulation clinical trials.
We have financed the development of rNAPc2 through public equity sales. Our rNAPc2 development plans, including the timeline, depend on our ability to enroll patients during the COVID-19 pandemic, the results of our Phase 2b clinical trial, FDA guidance, and availability of drug product, all of which are currently uncertain.
We own the clinical development program of rNAPc2, including Phase 2 clinical trials. If rNAPc2 is successfully developed, we believe it will have intellectual property protection, including 12 years of market exclusivity as an innovative biologic product under FDA law in the United States, 10 years data protection exclusivity in the European Union, or EU, and potentially patent protection in addition to this. We plan to pursue strategic co-development and partnering opportunities for rNAPc2 development and commercialization.
Gencaro™ (bucindolol hydrochloride) for Atrial Fibrillation
Gencaro™ (bucindolol hydrochloride) is a pharmacogenetically-targeted beta-adrenergic receptor antagonist with mild vasodilator properties that we are developing for the treatment of atrial fibrillation in patients with heart failure. We believe the pharmacology of Gencaro is unique and its efficacy can be enhanced by prescribing it to patients with a common genotypic variant that is present in approximately 50% of the North American and European general populations. This gene can be detected with a simple genetic test.
We are developing Gencaro to treat atrial fibrillation, or AF, in patients with chronic heart failure, or HF. AF is the most common form of cardiac arrhythmia, a disruption of the heart’s normal rhythm or rate. HF is a chronic condition in which the heart is unable to pump enough blood to meet the body’s needs. AF and HF commonly occur together. In HF patients, the development of AF leads to worsening symptoms, and increased risk of hospitalization and death. Current treatment options for AF in HF patients are limited, and can be invasive, costly and dangerous.
Our development plan for Gencaro focuses on the treatment of AF in patients with higher ejection fraction HF, those who have an ejection fraction, or EF, of 40% and higher who also have the genotype we believe is optimal for Gencaro efficacy. This population of HF encompasses more than half of all HF patients in the United States and Europe. There are currently few approved or effective drug therapies to treat AF or HF in this patient population.
Our development plan for Gencaro is based on our recent analysis of the Phase 2b clinical trial of Gencaro for the prevention of AF in HF patients, known as GENETIC-AF. This analysis showed novel results for Gencaro in patients in the clinical trial with EF’s of 40% and higher. We are planning a new design for a Phase 3 pivotal clinical trial of Gencaro based on this analysis that addresses what we believe are important clinical assessments, including the total amount of time that a patient experiences AF, known as AF burden, maintenance of normal sinus rhythm, rhythm control interventions such as electrical cardioversion, catheter ablation and use of anti-arrhythmic drugs and drug-related complications such as bradycardia. Based on these analyses, we were issued a United States patent in February 2021 for the use of Gencaro in this patient population. We believe this patent will substantially extend the patent protection for our planned development of Gencaro into 2039. We are seeking similar patent protection in other countries.
6.
We currently have an agreement with the FDA, known as a Special Protocol Assessment, or SPA, for the requirements of a Gencaro Phase 3 clinical trial, PRECISION-AF, that would support approval of Gencaro if successful. Based on our recent analyses of the GENETIC-AF data, we may alter the design of PRECISION-AF to focus on endpoints that are not covered in the SPA agreement.
We believe that patients with HF and AF represent a major unmet medical need, and this need is most pronounced in patients with EF values of 40% and above. This EF range constitutes more than half of all chronic HF in the United States and Europe, as well as in Japan and China, and there are currently few approved, effective or guideline-recommended therapies for these patients to treat either their AF or HF. AF is a very common complication in these patients, with estimates of AF incidence ranging from 40% to 60%. Beta-blockers approved for HF are commonly used off-label to control heart rate in these patients, but they are not considered effective in preventing AF and none are approved for patients with EF ≥ 40%. Other anti-arrhythmic drugs approved for the treatment of AF have adverse side effects and in HF patients are either contraindicated or have label warnings for use due to an increased risk of mortality. Interventional procedures for AF, such as catheter ablation and electrical cardioversion, are invasive, expensive, and often temporary; these interventions also typically require the continued use of beta blockers and other anti-arrhythmic drugs post-intervention.
We believe that Gencaro, if approved, may be a safe and more effective therapy for the treatment of higher ejection fraction HF patients with AF. We believe there are several potentially important attributes that would differentiate Gencaro from existing therapies, including:
| • | More effective rhythm control compared to the current standard of care; |
| • | Reduction in the need for catheter ablation, electrical cardioversion, or toxic anti-arrhythmic drugs; |
| • | Maintenance of rhythm control after a successful AF catheter ablation; |
| • | Effective rate control with lower risk of treatment-limiting bradycardia; |
| • | Reduction in symptoms and improvement in quality of life; |
| • | Reduced health care burden; |
| • | Foundational beta-blocker benefits for HF and unique evidence of efficacy in HF patients with AF; |
| • | One of the only drug therapies approved and shown effective for AF in HF patients with EF ≥ 40%, and the only one in its drug class. |
We have an international patent portfolio for Gencaro in the United States, the EU, and other major markets, as well as new chemical entity status, including a new patent that we believe will give us a strong intellectual property position to at least approximately 2039 in the United States; we have filed applications similar to this new patent in international territories. We have developed a laboratory platform for the diagnostic test that would be used to prescribe Gencaro; this platform was approved by FDA for use in the Phase 2B clinical trial. We retain all rights to this test platform; we expect to use it in future clinical trials, and we believe it could be one of multiple diagnostic platforms used for commercialization.
To support the continued development of rNAPc2 and Gencaro, we will need additional financing to fully fund the planned clinical trials, and our general and administrative costs through the clinical trials’ projected completion and potential commercialization. Considering the substantial time and costs associated with the development of rNAPc2 and Gencaro and the risk that we may be unable to raise a significant amount of capital on acceptable terms, we are also pursuing co-development and commercialization partnering opportunities with large pharmaceutical and/or specialty pharmaceutical companies and may pursue a strategic combination or other strategic transactions. If we are unable to obtain sufficient financing or are unable to complete a strategic transaction, we may discontinue our development activities on rNAPc2 or Gencaro or discontinue our operations.

Risks Associated with Our Business
Our business is subject to numerous risks, as more fully described in the section entitled “Risk Factors” beginning on page 10, and under similar headings in any applicable prospectus supplement or any document incorporated by reference herein. You should read these risks before you invest in our securities. We may be unable, for many reasons, including those that are beyond our control, to implement our business strategy. In particular, some of our risks include:
| • | If we are not able to successfully develop, obtain FDA approval for, and provide for the commercialization of rNAPc2 Gencaro in a timely manner, we may not be able to continue our business operations. |
| • | We will need to raise substantial additional funds through public or private equity or debt transactions and/or complete one or more strategic transactions, to continue development of rNAPc2, Gencaro or any of our other product candidates. If we are unable to raise such financing or complete such a transaction, we may not be able to continue operations. |
| • | Our audited financial statements for the fiscal year ended December 31, 2020 were prepared assuming that we will continue as a going concern. Our management has concluded that due to our need for additional capital, and the uncertainties surrounding our ability to raise such funding, there may be uncertainty about our ability to continue as a going concern in future years. |
| • | Our business could be adversely affected by the effects of health epidemics, including the ongoing COVID-19 global pandemic, in regions where we or third parties on which we rely may have clinical trial sites or other business operations. We anticipate having clinical trial sites in countries that have been directly affected by COVID-19 and depend on third party manufacturing operations for various stages of our supply chain. |
| • | We have received an SPA agreement from the FDA relating to our planned Phase 3 program for Gencaro. This SPA agreement does not guarantee approval of Gencaro or any other particular outcome from regulatory review. |
| • | If we are not able to maintain the requirements for listing on the Nasdaq Capital Market, we could be delisted, which could have a material adverse effect on our ability to raise additional funds as well as the price and liquidity of our common stock. |
| • | rNAPc2 may not yield results that will enable us to further develop it as a therapy and obtain regulatory approvals necessary to be used as a drug. |
| • | If we encounter difficulties enrolling patients in our clinical trial of rNAPc2, any potential enrollment milestones or potential regulatory approvals could be delayed or otherwise adversely affected. |
| • | Any future clinical trial for Gencaro will require the use of a third-party diagnostic services provider to administer a genetic test needed to identify the patient receptor genotypes of clinical trial participants, and as a result, we will be unable to directly control the timing, conduct and expense of the genetic test. |
| • | We will need to establish a collaborative arrangement with a third-party diagnostics services provider to obtain marketing clearance or approval of the companion genetic test. There is no guarantee that the FDA will grant timely clearance or approval of the genetic test, if at all, and failure to obtain such timely clearance or approval would adversely affect our ability to market Gencaro. |
| • | Our product candidates are subject to extensive regulation, which can be costly and time-consuming, and unsuccessful or delayed regulatory approvals could increase our future development costs or impair our future revenue. |
| • | If approved by the FDA, rNAPc2 or Gencaro will be entering a competitive marketplace and may not succeed. |

Warrants. We may issue warrants for the purchase of common stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or in combination with common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities. In this prospectus, we have summarized certain general features of the warrants under “Description of Warrants.” We urge you, however, to read the applicable prospectus supplement (and any related free writing prospectus that we may authorize to be provided to you) related to the particular series of warrants being offered, as well as the form of warrant and/or the warrant agreement and warrant certificate, as applicable, that contain the terms of the warrants. We have filed the forms of the warrant agreements and forms of warrant certificates containing the terms of the warrants that we may offer as exhibits to the registration statement of which this prospectus is a part. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant and/or the warrant agreement and warrant certificate, as applicable, that contain the terms of the particular series of warrants we are offering, and any supplemental agreements, before the issuance of such warrants.
Warrants may be issued under a warrant agreement that we enter into with a warrant agent. We will indicate the name and address of the warrant agent, if any, in the applicable prospectus supplement relating to a particular series of warrants.

An investment in our securities involves a high degree of risk. Before you make a decision to invest in our securities, you should consider carefully the risks described in the section entitled “Risk Factors” contained in the applicable prospectus supplement and in our most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q filed with the SEC, as well as any amendment or update thereto reflected in subsequent filings with the SEC or in any Current Report on Form 8-K we may file. The risks described in these documents are not the only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our securities to decline and you may lose part or all of your investment. Moreover, the risks described are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition. Please also read carefully the discussion below under the heading “Forward-Looking Statements.”
12.
This prospectus, any prospectus supplement and the documents we have filed with the SEC that are incorporated by reference herein contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These statements relate to future events or to our future operating or financial performance and involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performances or achievements expressed or implied by the forward-looking statements. All statements, other than statements of historical fact, are forward-looking statements, including, but not limited to, statements about:
| • | the timing and results of any clinical trials, including potential future clinical trials of rNAPc2, the potential for rNAPc2 to treat COVID-19, the potential for rNAPc2 to be the first novel anticoagulant and inhibitor of tissue factor for the treatment of COVID-19, rNAPc2’s potential use in combination with other antiviral drugs, future treatment options for patients with COVID-19, rNAPc2’s potential for future viral outbreaks beyond the current COVID-19 pandemic, and the ability to fund clinical trials and research of rNAPc2; |
| • | our ability to resume and fund PRECISION-AF clinical trials in the future as well as the potential for genetic variations to predict individual patient response to Gencaro, Gencaro’s potential to treat AF, future treatment options for patients with AF, the potential for Gencaro to be the first genetically-targeted atrial fibrillation prevention treatment; |
| • | our ability to obtain U.S. and foreign regulatory approval for our product candidates and the ability of our product candidates to meet existing or future regulatory standards; |
| • | our expectations regarding federal, state and foreign regulatory requirements; |
| • | the therapeutic benefits and effectiveness of our product candidates; |
| • | the accuracy of our estimates of the size and characteristics of the markets that may be addressed by our product candidates; |
| • | our ability to obtain additional funding or enter into a strategic or other transaction; |
| • | the extent to which our issued and pending patents may protect our products and technology; |
| • | the potential of such product candidates to lead to the development of safe or effective therapies; |
| • | our ability to enter into collaborations; |
| • | our ability to maintain listing of our common stock on a national exchange; |
| • | our future operating expenses, our future losses, our future expenditures, and the sufficiency of our cash resources to maintain operations; |
| • | our ability to compete with other companies that are or may be developing or selling products that are competitive with our product candidates; |
| • | anticipated trends and challenges in our potential markets; and |
| • | our ability to attract and retain key personnel. |
13.
In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “projects,” “predicts,” “potential,” or the negative of these terms or other similar expressions intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements reflect our current views with respect to future events, are based on assumptions and are subject to substantial risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements. Discussions containing these forward-looking statements may be found, among other places, under the heading “Risk Factors” contained in the applicable prospectus supplement, in any free writing prospectus we may authorize for use in connection with a specific offering, and under the headings “Business” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation” in our most recent annual report on Form 10-K and in our most recent quarterly report on Form 10-Q, as well as any amendments thereto reflected in subsequent filings with the SEC, each incorporated by reference herein in its entirety. Also, these forward-looking statements represent our estimates and assumptions only as of the date of the document containing the applicable statement. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this prospectus may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. If our forward-looking statements prove to be inaccurate, the inaccuracy may be material. Unless required by law, we undertake no obligation to update or revise any forward-looking statements to reflect new information or future events or developments. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. You should read this prospectus and the applicable prospectus supplement, together with the documents we have filed with the SEC that are incorporated by reference and any free writing prospectus that we may authorize for use in connection with this offering, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of the forward-looking statements in the foregoing documents by these cautionary statements.
14.
We will retain broad discretion over the use of the net proceeds from the sale of the securities offered by this prospectus. Except as described in any applicable prospectus supplement or in any free writing prospectus we have authorized for use in connection with a specific offering, we currently intend to use the net proceeds from the sale of the securities under this prospectus, if any, for working capital and general corporate purposes. We may also use a portion of the net proceeds to invest in or acquire businesses or technologies that we believe are complementary to our own. We will set forth in the prospectus supplement applicable to a specific offering our intended use for the net proceeds received from the sale of any securities in that offering.
The amounts and timing of our use of the net proceeds from any offerings hereunder will depend on a number of factors, such as the timing and progress of our clinical trials and research and development efforts, the timing of regulatory approval of our product candidates, if any, the timing and progress of any partnering and collaboration efforts, technological advances and the competitive environment for our product candidates. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from offerings hereunder. Accordingly, our management will have broad discretion in the timing and application of these proceeds. Pending application of the net proceeds as described above, we intend to temporarily invest the proceeds in short-term, interest-bearing instruments.

The following description of our capital stock and provisions of our amended and restated certificate of incorporation and amended and restated bylaws are summaries. You should also refer to our amended and restated certificate of incorporation and the amended and restated bylaws, which are filed as exhibits to the registration statement of which this prospectus is part.
General
As of the date of this prospectus, our amended and restated certificate of incorporation, as amended, or the Restated Certificate, authorizes us to issue 100,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, $0.001 par value per share. As of March 18, 2021, 14,410,143 shares of common stock were outstanding and no shares of preferred stock were outstanding.
The following summary description of our capital stock is based on the provisions of our Restated Certificate, our second amended and restated bylaws, or the Bylaws, and applicable provisions of the Delaware General Corporation Law. This information may not be complete in all respects and is qualified entirely by reference to the applicable provisions of our Restated Certificate, our Bylaws and the Delaware General Corporation Law. For information on how to obtain copies of our Restated Certificate and Bylaws, which are exhibits to the registration statement of which this prospectus is a part, see “Where You Can Find More Information.”
Common Stock
Voting Rights. Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors; provided, however, holders of our common stock may not, unless otherwise required by law, vote on any amendment to our Restated Certificate that relates solely to the terms of one or more series of preferred stock that we may issue if the holders of such preferred stock are entitled to vote on such amendment. In all such matters other than the election of directors, the affirmative vote of the majority of shares present in person, by remote communication, or represented by proxy at a meeting of the stockholders and entitled to vote generally on the subject matter shall be the act of the stockholders. Directors shall be elected by a plurality of the votes of the shares present in person, by remote communication, or represented by proxy at a meeting of the stockholders and entitled to vote generally on the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors to be elected at any particular time. See “Anti-Takeover Effects of Provisions of Delaware Law and Our Charter Documents – Certificate of Incorporation and Bylaws – Classified Board” for a description of elections of members of our board of directors.
Dividends. Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.
Liquidation. In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.
Rights and Preferences. Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of our preferred stock that we may designate in the future.
Fully Paid and Nonassessable. All of our outstanding shares of common stock are, and the shares of common stock to be issued in any offering hereunder will be, upon our receipt of the purchase price for such shares, fully paid and nonassessable.
16.
Preferred Stock
Pursuant to our Restated Certificate, our board of directors has the authority, without further action by our stockholders, to issue up to 5,000,000 shares of preferred stock, $0.001 par value per share, in one or more series, to establish from time to time the number of shares to be included in each such series, and to fix the designations, powers, preferences, privileges and relative participating, optional or special rights and the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, preemptive rights, voting rights, terms of redemption and repurchase, liquidation preferences and sinking fund terms, any or all of which may be greater than the rights of the common stock. Preferred stock may be convertible into our common stock or other securities of ours, or may be exchangeable for debt securities. Conversion may be mandatory or at the holder’s option and would be at prescribed conversion rates. Because our board of directors, without stockholder approval, can issue preferred stock with voting, conversion or other rights, preferred stock could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of the common stock and may adversely affect the voting power of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation.
Our board of directors will fix the rights, preferences, privileges, qualifications and restrictions of the preferred stock of each series that we sell under this prospectus and applicable prospectus supplements 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 reports 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:
| • | the title and stated value; |
| • | the number of shares we are offering; |
| • | the liquidation preference per share; |
| • | the purchase price per share; |
| • | the dividend rate per share, dividend period and payment dates and method of calculation for dividends; |
| • | whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate; |
| • | our right, if any, to defer payment of dividends and the maximum length of any such deferral period; |
| • | the procedures for any auction and remarketing, if any; |
| • | the provisions for a sinking fund, if any; |
| • | the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights; |
| • | any listing of the preferred stock on any securities exchange or market; |
| • | whether the preferred stock will be convertible into our common stock or other securities of ours, including warrants, and, if applicable, the conversion period, the conversion price, or how it will be calculated, and under what circumstances it may be adjusted; |
| • | whether the preferred stock will be exchangeable for debt securities, and, if applicable, the exchange period, the exchange price, or how it will be calculated, and under what circumstances it may be adjusted; |
| • | voting rights, if any, of the preferred stock; |
| • | preemptive rights, if any; |
| • | restrictions on transfer, sale or other assignment, if any; |
| • | a discussion of any material or special United States federal income tax considerations applicable to the preferred stock; |
| • | the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; |
17.
| • | any limitations on issuances of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock being issued as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and |
| • | any other specific terms, rights, preferences, privileges, qualifications or restrictions of the preferred stock. |
When we issue shares of preferred stock under this prospectus, upon our receipt of the purchase price for such shares, the shares will be fully paid and nonassessable and will not have, or be subject to, any preemptive or similar rights. Unless we specify otherwise in the applicable prospectus supplement, the preferred stock will rank, with respect to dividends and upon our liquidation, dissolution or winding up:
| • | senior to all classes or series of our common stock and to all of our equity securities ranking junior to the preferred stock; |
| • | on a parity with all of our equity securities the terms of which specifically provide that the equity securities rank on a parity with the preferred stock; and |
| • | junior to all of our equity securities the terms of which specifically provide that the equity securities rank senior to the preferred stock. |
The term “equity securities” does not include convertible debt securities.
The Delaware General Corporation Law provides that the holders of any class or series of preferred stock will have the right to vote separately as a class on any proposed amendment to the Restated Certificate that would alter or change the powers, preferences or special rights of the holders of such class or series of preferred stock so as to affect them adversely. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.
The issuance of preferred stock could adversely affect the voting power of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation. The issuance could have the effect of decreasing the market price of the common stock. The issuance of preferred stock also could have the effect of delaying, deterring or preventing a chance in control of us.
Outstanding Warrants
As of March 18, 2021, we had outstanding warrants to purchase 133,401 shares of our common stock, having an exercise price of $109.80 per share. Any of the outstanding warrants may be exercised by applying the value of a portion of the warrant, which is equal to the number of shares issuable under the warrant being exercised multiplied by the fair market value of the security receivable upon the exercise of the warrant, less the per share price, in lieu of payment of the exercise price per share.
These warrants, if unexercised, will expire on June 16, 2022.
Stock Options
As of March 18, 2021, there were 1,167,585 shares of common stock reserved for issuance under our equity incentive plans. Of this number, 596,497 shares were reserved for issuance upon exercise of outstanding options.
Anti-Takeover Effects of Provisions of Delaware Law and Our Charter Documents
Certificate of Incorporation and Bylaws
Our Restated Certificate and Second Amended and Restated Bylaws, or Bylaws, include a number of provisions that may deter or impede hostile takeovers or changes of control. These provisions include:
Issuance of Undesignated Preferred Stock. Under our Restated Certificate, our board of directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by the board of directors. The existence of authorized but unissued shares of preferred stock enables our board of directors to make it more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.
18.
Classified Board. Our Restated Certificate provides for a classified board of directors consisting of three classes of directors, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. This provision may have the effect of delaying a change in control of the board.
Board of Directors Vacancies. Our Restated Certificate and Bylaws authorize only our board of directors to fill vacant directorships, unless our board of directors determines by resolution that the stockholders shall fill such vacant directorships. In addition, the number of directors constituting our board of directors may be set only by resolution adopted by a majority vote of our entire board of directors. These provisions prevent a stockholder from increasing the size of our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.
Stockholder Action; Special Meetings of Stockholders. Our Restated Certificate provides that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. Under our Bylaws, stockholders are not permitted to cumulate their votes for the election of directors. Our Bylaws further provide that special meetings of the stockholders may be called by the chief executive officer, president, the board of directors, or by holders of common stock who hold, in the aggregate, not less than fifty percent (50%) of the outstanding shares of common stock for the purpose or purposes stated in the call of the meeting. These provisions may prevent stockholders from corporate actions as stockholders at times when they otherwise would like to do so.
Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our Bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders. Our Bylaws also specify certain requirements as to the form and content of a stockholder’s notice. These provisions may make it more difficult for our stockholders to bring matters before our annual meeting of stockholders or to nominate directors at our annual meeting of stockholders.
These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, these provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they may also reduce fluctuations in the market price of our shares that could result from actual or rumored takeover attempts.
Section 203 of the Delaware General Corporation Law
We are subject to Section 203 of the Delaware General Corporation Law. Section 203 generally prohibits certain Delaware corporations from engaging, under certain circumstances, in a “business combination” with any “interested stockholder for a period of three years following the time that such stockholder became an interested stockholder, unless:
| • | prior to such time the board of directors approved either the business combination or transaction which resulted in the stockholder becoming an interested stockholder; |
| • | upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers and (b) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or |
| • | at or subsequent to such time the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the interested stockholder. |
Section 203 defines a business combination to include:
| • | any merger or consolidation involving the corporation and the interested stockholder; |
| • | any sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions) involving the interested stockholder of 10% or more of the assets of the corporation (or its majority-owned subsidiary); |
| • | subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; |
19.
|
| • | subject to exceptions, any transaction involving the corporation that has the effect, directly or indirectly, of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; and |
| • | the receipt by the interested stockholder of the benefit, directly or indirectly (except proportionately as a stockholder of such corporation), of any loans, advances, guarantees, pledges or other financial benefits, other than certain benefits set forth in Section 203, provided by or through the corporation. |
In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person that is an affiliate or associate of such entity or person.
A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from a stockholders’ amendment approved by a majority of the outstanding voting shares. We have not “opted out” of these provisions and do not plan to do so. The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us.
Potential Effects of Authorized but Unissued Stock
Our shares of common stock and preferred stock available for future issuance without stockholder approval. We may utilize these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, to facilitate corporate acquisitions, payment as a dividend on the capital stock or as equity compensation to our service providers under our equity compensation plans.
The existence of unissued and unreserved common stock and preferred stock may enable our board of directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could render more difficult or discourage a third-party attempt to obtain control by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity of our management. In addition, our board of directors has the discretion to determine designations, rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of each series of preferred stock, all to the fullest extent permissible under the Delaware General Corporation Law and subject to any limitations set forth in our certificate of incorporation. The purpose of authorizing the board of directors to issue preferred stock and to determine the rights and preferences applicable to such preferred stock is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with possible financings, acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from acquiring, a majority of our outstanding voting stock.
Also, if we issue additional shares of our authorized, but unissued, common stock, these issuances will dilute the voting power and distribution rights of our existing common stockholders.
Amendments to Governing Documents
Generally, the amendment of our Restated Certificate requires approval by our board of directors and a majority vote of stockholders, provided that the provisions of our Restated Certificate relating to (i) the requirement that all stockholder action be taken only at a duly called annual meeting or special meeting; (ii) the authority and power of the board of directors and the procedure required to amend our Bylaws; (iii) the percentage of the shares necessary to amend the Restated Certificate; (iv) the elimination of directors’ personal liability for monetary damages arising from their negligence and gross negligence; and (v) indemnification of directors, officers and other persons requires approval of our stockholders holding at least 66-2/3% of our capital stock then outstanding and entitled to vote. Any amendment to our Bylaws requires the approval of either a majority of our board of directors or approval of our stockholders holding at least 66-2/3% of our capital stock then outstanding and entitled to vote.
Transfer Agent and Registrar
The transfer agent and registrar for our common stock is Computershare Trust Company N.A. The transfer agent for any series of preferred stock that we may offer under this prospectus will be named and described in the prospectus supplement for that series.

DESCRIPTION OF DEBT SECURITIES
We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.
We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.
The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.
General
The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.
We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.
We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:
| • | the title of the series of debt securities; |
| • | any limit upon the aggregate principal amount that may be issued; |
| • | the maturity date or dates; |
| • | the form of the debt securities of the series; |
| • | the applicability of any guarantees; |
| • | whether or not the debt securities will be secured or unsecured, and the terms of any secured debt; |
| • | whether the debt securities rank as senior debt, senior subordinated debt, subordinated debt or any combination thereof, and the terms of any subordination; |
| • | if the price (expressed as a percentage of the aggregate principal amount thereof) at which such debt securities will be issued is a price other than the principal amount thereof, the portion of the principal amount thereof payable upon declaration of acceleration of the maturity thereof, or if applicable, the portion of the principal amount of such debt securities that is convertible into another security or the method by which any such portion shall be determined; |
| • | the interest rate or rates, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the dates interest will be payable and the regular record dates for interest payment dates or the method for determining such dates; |
22.
| • | our right, if any, to defer payment of interest and the maximum length of any such deferral period; |
| • | if applicable, the date or dates after which, or the period or periods during which, and the price or prices at which, we may, at our option, redeem the series of debt securities pursuant to any optional or provisional redemption provisions and the terms of those redemption provisions; |
| • | the date or dates, if any, on which, and the price or prices at which we are obligated, pursuant to any mandatory sinking fund or analogous fund provisions or otherwise, to redeem, or at the holder’s option to purchase, the series of debt securities and the currency or currency unit in which the debt securities are payable; |
| • | the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof; |
| • | any and all terms, if applicable, relating to any auction or remarketing of the debt securities of that series and any security for our obligations with respect to such debt securities and any other terms which may be advisable in connection with the marketing of debt securities of that series; |
| • | whether the debt securities of the series shall be issued in whole or in part in the form of a global security or securities; the terms and conditions, if any, upon which such global security or securities may be exchanged in whole or in part for other individual securities; and the depositary for such global security or securities; |
| • | if applicable, the provisions relating to conversion or exchange of any debt securities of the series and the terms and conditions upon which such debt securities will be so convertible or exchangeable, including the conversion or exchange price, as applicable, or how it will be calculated and may be adjusted, any mandatory or optional (at our option or the holders’ option) conversion or exchange features, the applicable conversion or exchange period and the manner of settlement for any conversion or exchange; |
| • | if other than the full principal amount thereof, the portion of the principal amount of debt securities of the series which shall be payable upon declaration of acceleration of the maturity thereof; |
| • | additions to or changes in the covenants applicable to the particular debt securities being issued, including, among others, the consolidation, merger or sale covenant; |
| • | additions to or changes in the events of default with respect to the securities and any change in the right of the trustee or the holders to declare the principal, premium, if any, and interest, if any, with respect to such securities to be due and payable; |
| • | additions to or changes in or deletions of the provisions relating to covenant defeasance and legal defeasance; |
| • | additions to or changes in the provisions relating to satisfaction and discharge of the indenture; |
| • | additions to or changes in the provisions relating to the modification of the indenture both with and without the consent of holders of debt securities issued under the indenture; |
| • | the currency of payment of debt securities if other than U.S. dollars and the manner of determining the equivalent amount in U.S. dollars; |
| • | whether interest will be payable in cash or additional debt securities at our or the holders’ option and the terms and conditions upon which the election may be made; |
| • | the terms and conditions, if any, upon which we will pay amounts in addition to the stated interest, premium, if any and principal amounts of the debt securities of the series to any holder that is not a “United States person” for federal tax purposes; |
| • | any restrictions on transfer, sale or assignment of the debt securities of the series; and |
| • | any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities, any other additions or changes in the provisions of the indenture, and any terms that may be required by us or advisable under applicable laws or regulations. |
Conversion or Exchange Rights
We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option.
23.
We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.
Consolidation, Merger or Sale
Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, any successor to or acquirer of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.
Events of Default under the Indenture
Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:
| • | if we fail to pay any installment of interest on any series of debt securities, as and when the same shall become due and payable, and such default continues for a period of 90 days; provided, however, that a valid extension of an interest payment period by us in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of interest for this purpose; |
| • | if we fail to pay the principal of, or premium, if any, on any series of debt securities as and when the same shall become due and payable whether at maturity, upon redemption, by declaration or otherwise, or in any payment required by any sinking or analogous fund established with respect to such series; provided, however, that a valid extension of the maturity of such debt securities in accordance with the terms of any indenture supplemental thereto shall not constitute a default in the payment of principal or premium, if any; |
| • | if we fail to observe or perform any other covenant or agreement contained in the debt securities or the indenture, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive written notice of such failure, requiring the same to be remedied and stating that such is a notice of default thereunder, from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and |
| • | if specified events of bankruptcy, insolvency or reorganization occur. |
If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.
The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.
Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:
| • | the direction so given by the holder is not in conflict with any law or the applicable indenture; and |
| • | subject to its duties under the Trust Indenture Act, the trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding. |
A holder of the debt securities of any series will have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:
| • | the holder has given written notice to the trustee of a continuing event of default with respect to that series; |
24.
|
| • | the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request; |
| • | such holders have offered to the trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred by the trustee in compliance with the request; and |
| • | the trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer. |
These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.
We will periodically file statements with the trustee regarding our compliance with specified covenants in the indenture.
Modification of Indenture; Waiver
We and the trustee may change an indenture without the consent of any holders with respect to specific matters:
| • | to cure any ambiguity, defect or inconsistency in the indenture or in the debt securities of any series; |
| • | to comply with the provisions described above under “Description of Debt Securities-Consolidation, Merger or Sale;” |
| • | to provide for uncertificated debt securities in addition to or in place of certificated debt securities; |
| • | to add to our covenants, restrictions, conditions or provisions such new covenants, restrictions, conditions or provisions for the benefit of the holders of all or any series of debt securities, to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default or to surrender any right or power conferred upon us in the indenture; |
| • | to add to, delete from or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication and delivery of debt securities, as set forth in the indenture; |
| • | to make any change that does not adversely affect the interests of any holder of debt securities of any series in any material respect; |
| • | to provide for the issuance of and establish the form and terms and conditions of the debt securities of any series as provided above under “Description of Debt Securities-General” to establish the form of any certifications required to be furnished pursuant to the terms of the indenture or any series of debt securities, or to add to the rights of the holders of any series of debt securities; |
| • | to evidence and provide for the acceptance of appointment under any indenture by a successor trustee; or |
| • | to comply with any requirements of the SEC in connection with the qualification of any indenture under the Trust Indenture Act. |
In addition, under the indenture, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:
| • | extending the fixed maturity of any debt securities of any series; |
| • | reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption of any series of any debt securities; or |
| • | reducing the percentage of debt securities, the holders of which are required to consent to any amendment, supplement, modification or waiver. |
25.
Discharge
Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:
| • | provide for payment; |
| • | register the transfer or exchange of debt securities of the series; |
| • | replace stolen, lost or mutilated debt securities of the series; |
| • | pay principal of and premium and interest on any debt securities of the series; |
| • | maintain paying agencies; |
| • | hold monies for payment in trust; |
| • | recover excess money held by the trustee; |
| • | compensate and indemnify the trustee; and |
| • | appoint any successor trustee. |
In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.
Form, Exchange and Transfer
We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company, or DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.
At the option of the holder, subject to the terms of the indenture and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.
Subject to the terms of the indenture and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.
We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.
If we elect to redeem the debt securities of any series, we will not be required to:
| • | issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or |
| • | register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part. |
26.
Information Concerning the Trustee
The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indenture at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.
Payment and Paying Agents
Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.
We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.
All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.
Governing Law
The indenture and the debt securities will be governed by and construed in accordance with the internal laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.
27.
The following description, together with the additional information we may include in any applicable prospectus supplements and free writing prospectuses, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, which may consist of warrants to purchase common stock, preferred stock, and debt securities, and may be issued in one or more series. Warrants may be issued independently or together with common stock, preferred stock, or debt securities offered by any prospectus supplement, and may be attached to or separate from those securities. While the terms summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe the particular terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. However, no prospectus supplement shall fundamentally change the terms that are set forth in this prospectus or offer a security that is not registered and described in this prospectus at the time of its effectiveness.
We have filed forms of the warrant agreements and forms of warrant certificates as exhibits to the registration statement of which this prospectus is a part. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant agreement, if any, including a form of warrant certificate, that describes the terms of the particular series of warrants we are offering. The following summaries of material provisions of the warrants and the warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to the particular series of warrants that we may offer under this prospectus. We urge you to read any applicable prospectus supplements related to the particular series of warrants that we may offer under this prospectus, as well as any related free writing prospectuses, and the complete warrant agreements and warrant certificates that contain the terms of the warrants.
General
We will describe in the applicable prospectus supplement the terms of the series of warrants being offered, including:
| • | the offering price and aggregate number of warrants offered; |
| • | the currency for which the warrants may be purchased; |
| • | if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security; |
| • | if applicable, the date on and after which the warrants and the related securities will be separately transferable; |
| • | in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at, and currency in which, this principal amount of debt securities may be purchased upon such exercise; |
| • | in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise; |
| • | the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreements and the warrants; |
| • | the terms of any rights to redeem or call the warrants; |
| • | any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants; |
| • | the dates on which the right to exercise the warrants will commence and expire; |
| • | the manner in which the warrant agreements and warrants may be modified; |
| • | any material or special U.S. federal income tax consequences of holding or exercising the warrants; |
| • | the terms of the securities issuable upon exercise of the warrants; and |
| • | any other specific terms, preferences, rights or limitations of or restrictions on the warrants. |
28.
|
Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:
| • | in the case of warrants to purchase debt securities, the right to receive payments of principal of, or premium, if any, or interest on, the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or |
| • | in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any. |
Exercise of Warrants
Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.
Unless we otherwise specify in any applicable prospectus supplement, holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent in connection with the exercise of the warrant.
Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.
Enforceability of Rights by Holders of Warrants
Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.
Outstanding Warrants
As of March 18, 2021, we had outstanding warrants to purchase 133,401 shares of our common stock, having an exercise price of $109.80 per share. Any of the outstanding warrants may be exercised by applying the value of a portion of the warrant, which is equal to the number of shares issuable under the warrant being exercised multiplied by the fair market value of the security receivable upon the exercise of the warrant, less the per share price, in lieu of payment of the exercise price per share.
These warrants, if unexercised, will expire on June 16, 2022.
29.
We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee, depositary or warrant agent maintain for this purpose as the “holders” of those securities. These persons are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as “indirect holders” of those securities. As we discuss below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.
Book-Entry Holders
We may issue securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.
Only the person in whose name a security is registered is recognized as the holder of that security. Securities issued in global form will be registered in the name of the depositary or its participants. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities, and we will make all payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.
As a result, investors in a book-entry security will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect holders, and not legal holders, of the securities.
Street Name Holders
We may terminate a global security or issue securities in non-global form. In these cases, investors may choose to hold their securities in their own names or in “street name.” Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.
For securities held in street name, we or any applicable trustee or depositary will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we or any applicable trustee or depositary will make all payments on those securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect holders, not holders, of those securities.
Legal Holders
Our obligations, as well as the obligations of any applicable trustee and of any third parties employed by us or a trustee, run only to the legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a security or has no choice because we are issuing the securities only in global form.
For example, once we make a payment or give a notice to the legal holder, we have no further responsibility for the payment or notice even if that legal holder is required, under agreements with its participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the approval of the legal holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture or for other purposes. In such an event, we would seek approval only from the legal holders, and not the indirect holders, of the securities. Whether and how the holders contact the indirect holders is up to the legal holders.
30.
Special Considerations for Indirect Holders
If you hold securities through a bank, broker or other financial institution, either in book-entry form because the securities are represented by one or more global securities or in street name, you should check with your own institution to find out:
| • | the performance of third party service providers; |
| • | how it handles securities payments and notices; |
| • | whether it imposes fees or charges; |
| • | how it would handle a request for the holders’ consent, if ever required; |
| • | whether and how you can instruct it to send you securities registered in your own name so you can be a holder, if that is permitted in the future; |
| • | how it would exercise rights under the securities if there were a default or other event triggering the need for holders to act to protect their interests; and |
| • | if the securities are in book-entry form, how the depositary’s rules and procedures will affect these matters. |
Global Securities
A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms.
Each security issued in book-entry form will be represented by a global security that we issue to, deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, DTC will be the depositary for all securities issued in book-entry form.
A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under the section entitled “Special Situations When a Global Security Will Be Terminated” in this prospectus. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and legal holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a legal holder of the security, but only an indirect holder of a beneficial interest in the global security.
If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.
Special Considerations for Global Securities
The rights of an indirect holder relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security.
If securities are issued only in the form of a global security, an investor should be aware of the following:
| • | an investor cannot cause the securities to be registered in his or her name, and cannot obtain non-global certificates for his or her interest in the securities, except in the special situations we describe below; |
| • | an investor will be an indirect holder and must look to his or her own bank or broker for payments on the securities and protection of his or her legal rights relating to the securities, as we describe above; |
31.
| • | an investor may not be able to sell interests in the securities to some insurance companies and to other institutions that are required by law to own their securities in non-book-entry form; |
| • | an investor may not be able to pledge his or her interest in a global security in circumstances where certificates representing the securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective; |
| • | the depositary’s policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor’s interest in a global security; |
| • | we and any applicable trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership interests in a global security, nor do we or any applicable trustee supervise the depositary in any way; |
| • | the depositary may, and we understand that DTC will, require that those who purchase and sell interests in a global security within its book-entry system use immediately available funds, and your broker or bank may require you to do so as well; and |
| • | financial institutions that participate in the depositary’s book-entry system, and through which an investor holds its interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the securities. |
There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.
Special Situations When a Global Security Will Be Terminated
In a few special situations described below, the global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own banks, brokers or other financial institutions to find out how to have their interests in securities transferred to their own name, so that they will be direct holders. We have described the rights of holders and street name investors above.
Unless we provide otherwise in the applicable prospectus supplement, the global security will terminate when the following special situations occur:
| • | if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security and we do not appoint another institution to act as depositary within 90 days; |
| • | if we notify any applicable trustee that we wish to terminate that global security; or |
| • | if an event of default has occurred with regard to securities represented by that global security and has not been cured or waived. |
The applicable prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the applicable prospectus supplement. When a global security terminates, the depositary, and not we or any applicable trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.
32.
We may sell the securities from time to time pursuant to underwritten public offerings, direct sales to the public, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, or directly to one or more purchasers. We may distribute securities from time to time in one or more transactions:
| • | at a fixed price or prices, which may be changed; |
| • | at market prices prevailing at the time of sale; |
| • | at prices related to such prevailing market prices; or |
| • | at negotiated prices. |
We may also sell equity securities covered by this registration statement in an “at the market offering” as defined in Rule 415 under the Securities Act. Such offering may be made into an existing trading market for such securities in transactions at other than a fixed price, either:
| • | on or through the facilities of The NASDAQ Capital Market or any other securities exchange or quotation or trading service on which such securities may be listed, quoted or traded at the time of sale; and/or |
| • | other than on The NASDAQ Capital Market or such other securities exchanges or quotation or trading services. |
Such at the market offerings, if any, may be conducted by underwriters acting as principal or agent.
A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:
| • | the name or names of the underwriters, if any; |
| • | the purchase price of the securities or other consideration therefor, and the proceeds, if any, we will receive from the sale; |
| • | any over-allotment options under which underwriters may purchase additional securities from us; |
| • | any agency fees or underwriting discounts and other items constituting agents’ or underwriters’ compensation; |
| • | any public offering price; |
| • | any discounts or concessions allowed or reallowed or paid to dealers; and |
| • | any securities exchange or market on which the securities may be listed. |
Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement.
If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. 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 reallowed 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 applicable prospectus supplement. Unless the applicable 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 applicable 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.
We may provide agents and underwriters with indemnification against 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 and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.
All securities we may offer, other than common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.
Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under 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 the 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 the 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.
In compliance with guidelines of the Financial Industry Regulatory Authority, or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and the applicable prospectus supplement.
Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities offered by this prospectus, and any supplement thereto, will be passed upon for us by Cooley LLP, Broomfield, Colorado. Additional legal matters may be passed upon for us or any underwriters, dealers or agents by counsel that we name in any applicable prospectus supplement.
