Seelos Therapeutics, Inc.

Seelos Therapeutics, Inc. (Nasdaq: SEEL), together with its subsidiaries, or collectively, “Seelos”, the “Company”, “we”, “us” and “our”, is our trademarka clinical stage biopharmaceutical company focused on achieving efficient development of products that address significant unmet needs in Central Nervous System (“CNS”) disorders and other rare disorders.

Our business model is to advance multiple late-stage therapeutic candidates with proven mechanisms of action that address large markets with unmet medical needs and for which there is a strong economic and scientific rationale for development.

Lead Programs

Our lead programs are currently SLS-002 for the treatment of Acute Suicidal Ideation and Behavior (“ASIB”) in patients with Major Depressive Disorder (“MDD”) and SLS-005 for the potential treatment of Amyotrophic Lateral Sclerosis (“ALS”) and Spinocerebella Ataxia (“SCA”). SLS-005 for the potential treatment of Sanfilippo syndrome currently requires additional natural history data, which is being considered.

SLS-002 is intranasal racemic ketamine with two investigational new drug applications (“INDs”). The lead program is focused on the treatment of ASIB in MDD. SLS-002 was originally derived from a Javelin Pharmaceuticals, Inc./Hospira, Inc. program with 16 clinical studies involving approximately 500 subjects. SLS-002 addresses an unmet need for an efficacious drug to treat suicidality in the United States. Traditionally, anti-depressants have been used in this setting but many of the existing treatments are known to contribute to an increased risk of suicidal thoughts in some circumstances, and if and when they are effective, it often takes weeks for the full therapeutic effect to be manifested. We believe there is a large opportunity in the United States and European markets for products in this space. Based on information gathered from the databases of the Agency for Healthcare Research and Quality, there were approximately 1,000,000 visits to emergency rooms for suicide attempts in 2013 in the United States alone. Experimental studies suggest ketamine has the potential to be a rapid, effective treatment for refractory depression and suicidality.

The clinical development program for SLS-002 includes two parallel healthy volunteer studies (Phase I). We announced interim data from our Phase I study of SLS-002 during the quarterly period ended March 31, 2020. As a result, in March 2020, we completed a Type C meeting with the U.S. Food and Drug Administration (“FDA”) and received guidance to conduct a Phase II proof of concept (“PoC”) study of SLS-002 for ASIB in patients with MDD, to support the further clinical development of this product candidate, together with nonclinical data under development.

As a result of the Type C meeting and the Fast Track designation for SLS-002 for the treatment of ASIB in patients with MDD, we believe we are well positioned to pursue the FDA’s expedited programs for drug development and review.

On June 23, 2020, we announced the final safety data from our Phase I pharmacokinetics/pharmacodynamics study of intranasal racemic ketamine (SLS-002) as well as the planned design of a Phase II double blind, placebo-controlled PoC study for ASIB in subjects with MDD. We initiated this PoC study in two parts: Part 1 was an open-label study of 17 subjects, and is being followed by Part 2, which is pendinga double blind, placebo-controlled study of approximately 120 subjects. On January 15, 2021, we announced dosing of the first subjects in Part 1 of the PoC study. On March 5, 2021, we announced the completion of open-label enrollment of subjects in Part 1 of the PoC study. We announced the initial topline data from Part 1 of the PoC study on May 17, 2021.

On July 6, 2021, we announced dosing of the first subject in Part 2 of the planned registration directed study. Based on feedback from a Type C meeting with the FDA in June 2021, we are planning to increase the subjects in Part 2 to increase the sample size and subjectpower to support our agreementpotential marketing application. Also, we are planning a Phase II clinical trial to run concurrently with Warner Chilcott Company, Inc., nowthe Part 2 registration directed study to observe patients that complete Part 2 of the PoC study for six months following completion of treatment to measure longer term durability, gauge retreatment and associated dosing.

SLS-005 is IV trehalose, a subsidiary of Allergan plc, or Allergan. Vitaros®protein stabilizer that crosses the blood-brain-barrier and activates autophagy and the lysosomal pathway. Based on preclinical and in vitro studies, there is a registered trademarksound scientific rationale for developing trehalose for the treatment of Ferring International Center S.A,ALS, SCA and other indications such as Sanfilippo Syndrome. Trehalose is a low molecular weight disaccharide (0.342 kDa) that protects against pathological processes in cells. It has been shown to penetrate muscle and cross the blood-brain-barrier. In animal models of several diseases associated with abnormal cellular protein aggregation, it has been shown to reduce pathological aggregation of misfolded proteins as well as to activate autophagy pathways through the activation of Transcription Factor EB (“TFEB”), a key factor in lysosomal and autophagy gene expression. Activation of TFEB is an emerging therapeutic target for a number of diseases with pathologic accumulation of storage material.

Trehalose 90.5 mg/mL IV solution has demonstrated promising clinical potential in prior Phase II clinical development for oculopharyngeal muscular dystrophy (“OPMD”) and spinocerebellar ataxia type 3 (“SCA3”), also known as Machado Joseph disease, with no significant safety signals to date and encouraging efficacy results. Pathological accumulation of protein aggregates within cells, whether in the CNS or Ferring, in certain countries outsidemuscle, eventually leads to loss of function and ultimately cell death. Prior preclinical studies indicate that this platform has the potential to prevent mutant protein aggregation in other devastating PolyA/PolyQ diseases.

We own two United States patents for parenteral administration of trehalose for patients with OPMD and SCA3, both of which are expected to expire in 2034. In addition, Orphan Drug Designation (“ODD”) for OPMD and SCA3 has been secured in the United States and in the European Union (“EU”). In February 2019, we assumed a collaborative agreement, turned subsequently into a research grant, with Team Sanfilippo Foundation, a nonprofit medical research foundation founded by parents of children with Sanfilippo Syndrome. On April 30, 2020, we were granted ODD for SLS-005 in Sanfilippo Syndrome from the FDA. SLS-005 was previously granted ODD from the FDA and European Medicines Agency for SCA3 and OPMD as well as Fast Track designation for OPMD. On April 22, 2020, we received a Notice of Allowance from the United States Patent and Trademark Office for our U.S. patent number 10,751,353 (application number 16/263,707) titled “COMPOSITIONS AND METHODS FOR TREATING AN AGGREGATION DISEASE OR DISORDER” for trehalose (SLS-005). The allowed claims cover the composition of matter and method of use for trehalose (SLS-005) for treating a disease or disorder selected from any one of the United States. In addition,following: spinal and bulbar muscular atrophy, dentatombral-pallidoluysian atrophy, Pick’s disease, corticobasal degeneration, progressive supranuclear palsy,

frontotemporal dementia or parkinsonism linked to chromosome 17. On May 15, 2020, we own trademarkswere granted Rare Pediatric Disease Designation (“RPDD”) for NexACT®SLS-005 in Sanfilippo Syndrome from the FDA.

At present, we are initiating the startup activities for a clinical study in ALS. In December 2020, we announced the selection of SLS-005 for the Healey ALS platform trial led by Harvard Medical School, Massachusetts. The Healey ALS platform trial is designed to study multiple potential treatments for ALS simultaneously. The platform trial model aims to greatly accelerate the fullest extent under applicable law,study access, reduce costs and shorten development timelines. Our pivotal Phase IIb/III study for SLS-005 in ALS is expected to screen its first subject in the fourth quarter of 2021. In November 2021, we announced the FDA acceptance of an IND and grant of fast track designation for SLS-005 for the treatment of SCA. We have begun the start up activities for a Phase IIb/III study for SCA.

Additionally, we are developing several preclinical programs, most of which have well-defined mechanisms of action, including SLS-004, licensed from Duke University, and SLS-007, licensed from The Regents of the University of California, for the potential treatment of Parkinson’s Disease (“PD”), SLS-008, targeted at chronic inflammation in asthma, atopic dermatitis and orphan indications such as pediatric esophagitis, SLS-010 in narcolepsy and related disorders and SLS-012, an injectable therapy for post-operative pain management.

Strategy and Ongoing Programs

SLS-002: The clinical development program for SLS-002 includes two parallel healthy volunteer studies (Phase I). Following these Phase I studies, we completed a Type C meeting with the FDA in March 2020 and received guidance to conduct a Phase II PoC study of SLS-002 for ASIB in subjects with MDD. We have completed enrollment of subjects in and released topline data for Part 1 of our rights or thatopen-label study on May 17, 2021.

We are continuing to consider trials in Sanfilippo Syndrome and are seeking more natural history data based on the guidance from regulatory agencies.

SLS-004 is an all-in-one lentiviral vector, targeted for gene editing through DNA methylation within intron 1 of the synuclein alpha (“SNCA”) gene responsible for expressing alpha-synuclein protein. SLS-004, when delivered to dopaminergic neurons derived from human induced pluripotent stem cells of a PD patient, modified the expression on alpha-synuclein (“α-synuclein”) and exhibited reversal of the disease-related cellular-phenotype characteristics of the neurons. The role of mutated SNCA in PD pathogenesis and the need to maintain the normal physiological levels of α-synuclein protein emphasize the yet unmet need to develop new therapeutic strategies, such as SLS-004, targeting the regulatory mechanism of α-synuclein expression. On May 28, 2020, we announced the initiation of a preclinical study of SLS-004 in PD through an all-in-one lentiviral vector targeting the SNCA gene. We are constructing a bimodular viral system harboring an endogenous α-synuclein transgene and inducible regulated repressive CRISPR/Cas9-unit to achieve constitutive activation and inducible suppression of PD-related pathologies. We announced positive in vivo data demonstrating down-regulation of SNCA mRNA and protein expression on July 7, 2021 under this study.

SLS-006 is a true partial dopamine agonist, originally developed by Wyeth Pharmaceuticals, Inc., with previous clinical studies on 340 subjects in various Phase I and Phase II studies. It is a potent D2/D3 agonist/antagonist that has shown promising efficacy with statistical significance in Phase II studies in early-stage PD patients and an attractive safety profile. Moreover, it has also shown synergistic effect with reduced doses of L-DOPA. We are considering studies to advance the product candidate into late-stage trials.

SLS-007 is a rationally designed peptide-based approach, targeting the nonamyloid component core (“NACore”) of α-synuclein to inhibit the protein from aggregation. Recent in vitro and cell culture research has shown that SLS-007 has the ability to stop the propagation and seeding of α- synuclein aggregates. We will evaluate the potential for in vivo delivery of SLS-007 in a PD transgenic mice model. The goal will be to establish in vivo pharmacokinetics/pharmacodynamics and target engagement parameters of SLS-007, a family of anti- α -synuclein peptidic inhibitors. On June 25, 2020, we announced the initiation of a preclinical study of SLS-007 in PD delivered through an adeno associated viral (“AAV”) vector targeting the non-amyloid component core of α-synuclein. We have initiated an in vivo preclinical study of SLS-007 in rodents to assess the ability of two specific novel peptides, S62 and S71, delivered via AAV1/2 viral vector, to protect dopaminergic function in the preformed α-synuclein fibril rodent model

of PD. Production of AAV1/2 vectors encoding each of the two novel peptides incorporating hemagglutinin tags has already been completed. This preclinical study is designed to establish the in vivo pharmacokinetic and pharmacodynamic profiles and target engagement parameters of SLS-007.

We intend to become a leading biopharmaceutical company focused on the development of innovative product candidates in the areas of urologyneurological and rheumatology. psychiatric disorders, including orphan indications. Our business strategy includes:

·Advancing SLS-002 in ASIB in MDD and post-traumatic stress disorder;
·Advancing SLS-004 in PD;
·Advancing SLS-005 in ALS and Sanfilippo syndrome;
·Advancing SLS-007 in PD as a monotherapy; and
·Acquiring synergistic assets in the central nervous system therapy space through licensing and partnerships.

We also have two legacy product candidates currently in development. Vitaros iscandidates: a product candidate in the United States under development for the treatment of erectile dysfunction, which we in-licensed from Warner Chilcott Company, Inc., now a subsidiary of Allergan. RayVa is ourAllergan plc; and a product candidate inwhich has completed a Phase 2 developmentIIa clinical trial for the treatment of Raynaud’s Phenomenon, secondary to scleroderma, for which we own worldwide rights.

Recent Developments

Convertible Note Financing

On November 23, 2021, we entered into a Securities Purchase Agreement (the “Lind Purchase Agreement”) with Lind Global Asset Management V, LLC (the “Investor”) pursuant to which, among other things, on November 23, 2021 (the “Closing Date”), we issued and sold to the Investor, in a private placement transaction (the “Private Placement”), in exchange for the payment by the Investor of $20,000,000, (1) a convertible promissory note (the “First Note”) in an aggregate principal amount of $22,000,000 (the “Principal Amount”), which will bear no interest until the first anniversary of the issuance of the First Note and will thereafter bear interest at a rate of 5% per annum, and mature on November 23, 2024 (the “Maturity Date”), and (2) 534,759 shares (the “Closing Shares”) of Common Stock.

At the first anniversary of the Closing Date, we will have the option, at our securities involvessole discretion, to issue to the Investor a high degreeconvertible promissory note (the “Second Note”) in the principal amount of risk. Prior$11,000,000 in exchange for the payment by the Investor of $10,000,000. At the earlier of (i) the two-year anniversary of the Closing Date, or (ii) the successful readout for SLS-005 in ALS, and subject to makingthe mutual agreement of us and the Investor, we will issue to the Investor a decision about investingconvertible promissory note (the “Third Note”) in the principal amount of $11,000,000 in exchange for the payment by the Investor of $10,000,000. In the event of the filing of a new drug application with the U.S. Food & Drug Administration for either SLS-002 or SLS-005, and subject to the mutual agreement of us and the Investor, we will issue to the Investor a convertible promissory note (the “Fourth Note”, and collectively with the First Note, the Second Note, and the Third Note, the “Notes”) in the principal amount of $11,000,000 in exchange for the payment by the Investor of $10,000,000. The Second Note, the Third Note and the Fourth Note, if issued, would be in substantially the same form as the First Note.

At any time following August 23, 2022, from time to time and before the Maturity Date, the Investor will have the option to convert any portion of the then-outstanding Principal Amount of the First Note into shares of Common Stock at a price per share of $6.00, subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions (the “Conversion Price”). At any time prior August 23, 2022, we will have the right to prepay, in whole or in part (exercisable by us at any time or from time to time during such period), up to an aggregate of $14,666,667 of the outstanding Principal Amount of the First Note with no penalty. If we do not prepay any amounts of the First Note prior to August 23, 2022 then, commencing August 23, 2022, we will have the right to prepay, in whole or in part (exercisable by us at any time or from time to time prior to the Maturity Date), up to the full remaining Principal Amount of the First Note with no penalty; however, if we exercise such prepayment right, the Investor will have the option to convert up to thirty-three and one-third percent (331/3%) of the amount that we elect to prepay at the Conversion Price. If we prepay any amounts of the First Note prior to August 23, 2022 then, commencing November 23, 2022, we will not have the right to prepay any amounts of the First Note between August 23, 2022 to November 23, 2022 and, commencing November 23, 2022, we will have the right to prepay, in whole or in part (exercisable us at any time or from time to time prior to the Maturity Date) up to the full remaining Principal Amount of the First Note with no penalty; however, if we exercise such prepayment right, the Investor will have the option to convert up to thirty-three and one-third percent (331/3%) of the amount that we elect to prepay at the Conversion Price.

Subject to certain exceptions, we will be required to direct proceeds from any subsequent debt financings (including subordinated debt, convertible debt or mandatorily redeemable preferred stock but other than purchase money debt or capital lease obligations or other indebtedness incurred in the ordinary course of business) to repay the Notes, unless waived by the Investor in advance.

Beginning on November 23, 2022, the First Note will amortize in twenty-four monthly installments equal to the quotient of (i) the then-outstanding Principal Amount of the First Note, divided by (ii) the number of months remaining until the Maturity Date. All amortization payments will be payable, at our securities,sole option, in cash, shares of Common Stock or a combination of both. In addition, commencing on the last business day of the first month following November 23, 2022, we will pay, on a monthly basis, all interest that has accrued and remains unpaid on the then-outstanding Principal Amount of the First Note. Any portion of an amortization payment or interest payment that is paid in shares of Common Stock will be priced at 90% of the average of the five lowest daily volume weighted average prices of the Common Stock during the 20 trading days prior to the date of issuance of the shares. If, after the first amortization payment, we elect to make any amortization payments in cash, we will pay a 5% premium on each cash payment.

In conjunction with the Lind Purchase Agreement and the First Note, on the Closing Date, we entered into a security agreement with the Investor, which provides the Investor with a first priority lien on our assets and properties.

License Agreement and Purchase Agreement

On November 24, 2021, we entered into an exclusive license agreement (the “License Agreement”) with iXBEL and the Purchase Agreement with iXBEL. Pursuant to the License Agreement, among other things, iXBEL granted us an exclusive, sublicensable, perpetual, worldwide (excluding certain jurisdictions identified in the License Agreement) and irrevocable right and license to certain of iXBEL’s licensed patents, know-how, and technological information, including access to iXBEL’s research, development and manufacturing capabilities, to enable the further development, manufacture, promotion and commercialization of WafermineTM and certain other existing and to be developed iXBEL wafer-based delivery technologies, in all cases for sublingual administration of ketamine. In addition, iXBEL will supply us with sufficient product for the potential treatment of 400 patients, with further supplied amounts to be determined by the parties. We granted iXBEL an exclusive license to exploit technology developed under the License Agreement outside of the licensed territory and to undertake limited, non-exclusive research and development activities in the territory. We further agreed not to undertake certain activities with respect to products competitive with those licensed under the License Agreement during the term of the License Agreement.

As consideration for the license under the License Agreement, we agreed to (i) pay iXBEL an upfront fee of $9,000,000 comprised of $3,500,000 in cash and 2,570,266 restricted shares of our Common Stock (calculated in accordance with the Purchase Agreement); and (ii) pay certain development, regulatory and commercial milestones and royalty payments as further set out in the License Agreement.

Pursuant to the Purchase Agreement, we also agreed to reimburse iXBEL for the difference in value (the “Shortfall Amount”) in the event the aggregate Value (as defined below) of the 2,570,266 shares of our Common Stock issued to iXBEL pursuant to the Purchase Agreement is less than $5,500,000. The Shortfall Amount may be paid in cash, additional shares of Common Stock (the “Additional Shares”) or a combination of the foregoing, as follows: (A) for the first $1,100,000 of any Shortfall Amount, we will issue such number of Additional Shares as is equal to the quotient of the lesser of (i) the Shortfall Amount and (ii) $1,100,000, divided by the Value of one share of Common Stock, or pay cash to iXBEL (or a combination of the foregoing) at our sole election; and (B) for the amount of the Shortfall Amount greater than $1,100,000, if any, we will pay cash to iXBEL. For purposes of the foregoing calculation, the “Value” of one share of our Common Stock will be equal to the volume weighted average closing price of our Common Stock, as reported on The Nasdaq Stock Market LLC, for the ten consecutive trading days ending on the third trading date prior to the effective date of the registration statement of which this prospectus forms a part.

Pursuant to the Purchase Agreement, we have agreed to file a registration statement registering the shares of Common Stock that we issue to iXBEL pursuant to the Purchase Agreement, including any Additional Shares, on or before December 24, 2021. The registration statement of which this prospectus forms a part is being filed to satisfy this obligation. We are registering the Shortfall Shares to cover up to 642,566 Additional Shares that we may issue pursuant to the Purchase Agreement.

Coronavirus (COVID-19)

In March 2020, we began taking precautionary measures to protect the health and safety of our employees and contractors and further assessing the actual and potential impact of the coronavirus (“COVID-19”) pandemic on our business, financial condition and operations. COVID-19 infections have been reported throughout the United States, along with other jurisdictions in which our suppliers, partners and collaborators operate. In addition, COVID-19 has caused disruption and volatility in the global capital markets and has led to an economic slowdown. Certain national, provincial, state and local governmental authorities have issued proclamations and/or directives aimed at minimizing the spread of COVID-19 and additional, more restrictive proclamations and/or directives may be issued in the future. Before the recent COVID-19 outbreak, most of our employees worked remotely. In addition, our ongoing clinical trial for SLS-002 in acute suicidal ideation and behavior ASIB in patients with MDD completed the clinical testing phase in February 2020. On June 23, 2020, we released the final pharmacokinetics/pharmacodynamics portion of the data. Also, we did not experience any significant delays with opening our clinical sites for SLS-002 during the first nine months of 2021 and have not experienced any such delays during the fourth quarter of 2021 to date. Accordingly, the impact of the travel restrictions and shelter-in-place orders have not had a material impact on our operations to date. Additionally, the pandemic has not materially affected our liquidity as we maintain our resources in the form of cash.

In addition, although we do not currently expect the preventative measures taken to date to have a material adverse impact on our business for the fourth quarter of 2021, the ultimate impact of the COVID-19 pandemic on our business, financial condition and results of operations is unknown and will depend on future developments and risks, which are highly uncertain and cannot be predicted. These developments and risks include, among others, the duration and severity of the COVID-19 pandemic, the impact on capital markets, the impact on our partners and the regulatory agencies that oversee our sector and any additional preventative and protective actions that governmental authorities, or we, may implement, any of which may result in an extended period of business disruption, including potential delays in commencing future clinical trials or in completing enrollment for any clinical trials we may commence or in the FDA or other regulatory agencies conducting in-person inspections or accommodations for alternatives to in-person inspections. Any resulting financial impact cannot be reasonably estimated at this time, but the COVID-19 pandemic may force us to make adjustments to our business, our plans and our timeline for developing assets, including our programs. In addition, the pandemic is currently not anticipated to have a material adverse impact on our business, financial condition and results of operations, including our ability to raise additional capital. However, if the effects of the pandemic worsen into the first quarter of 2022, it could have a material adverse impact on our business. See the heading “Risk Factors” contained in this prospectus, any applicable prospectus supplement and any related free writing prospectus and under similar headings in the other documents that are incorporated by reference into this prospectus for an additional discussion of risks related to COVID-19.

We intendare filing the registration statement of which this prospectus forms a part to usepermit the netSelling Stockholder to resell the Shares. We will not receive any proceeds from the sale of the Shares by the Selling Stockholder.

The Selling Stockholder will pay any underwriting fees, discounts and commissions attributable to the sale of the Shares and any similar expenses it incurs in disposing of the Shares. We will bear all other costs, fees, and expenses incurred in effecting the registration of the Shares covered by this prospectus. These may include, without limitation, all registration and filing fees, printing fees and fees and expenses of our counsel and accountants in connection with the registration of the Shares covered by this prospectus.

SELLING STOCKHOLDER

Unless the context otherwise requires, as used in this prospectus, “Selling Stockholder” includes the selling stockholder listed below and donees, pledgees, permitted transferees or other successors-in-interest selling shares received after the date of this prospectus from a selling stockholder as a gift, pledge or other non-sale related transfer.

We have prepared this prospectus to allow the Selling Stockholder or its successors, assignees or other permitted transferees to sell or otherwise dispose of, from time to time, up to 3,212,832 shares of our Common Stock. The Issued Shares were issued, and the Shortfall Shares, if any, will be issued, to the Selling Stockholder pursuant to the Purchase Agreement and in reliance on the exemption from securities asregistration in Section 4(a)(2) under the Securities Act and Rule 506 promulgated thereunder.

The shares of Common Stock to be offered by the Selling Stockholder are “restricted” securities under applicable federal and state securities laws and are being registered under the Securities Act to give the Selling Stockholder the opportunity to sell these shares publicly. The registration of these shares does not require that any of the shares be offered or sold by the Selling Stockholder. Subject to these resale restrictions, the Selling Stockholder may from time to time offer and sell all or a portion of its shares indicated below in privately negotiated transactions or on the Nasdaq Capital Market or any other market on which our Common Stock may subsequently be listed or quoted.

The registered shares may be sold directly or through brokers or dealers, or in a distribution by one or more underwriters on a firm commitment or best effort basis. To the extent required, the names of any agent or broker-dealer and applicable commissions or discounts and any other required information with respect to any particular offering will be set forth in the applicablea prospectus supplement. See the section of this prospectus entitled “Plan of Distribution”. The Selling Stockholder and any agents or broker-dealers that participate with the Selling Stockholder in the distribution of registered shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of the registered shares may be deemed to be underwriting commissions or discounts under the Securities Act.

No estimate can be given as to the amount or percentage of Common Stock that will be held by the Selling Stockholder after any sales made pursuant to this prospectus because the Selling Stockholder is not required to sell any of the Shares being registered under the registration statement of which this prospectus forms a part. The following table assumes that the Selling Stockholder will sell all of the Shares listed in this prospectus.

Unless otherwise indicated in the footnotes below, the Selling Stockholder has not had any material relationship with us or any of our affiliates within the past three years other than as a security holder.

We have prepared this table based on written representations and information furnished to us by or on behalf of the Selling Stockholder. Since the date on which the Selling Stockholder provided this information, the Selling Stockholder may have sold, transferred or otherwise disposed of all or a portion of the shares of Common Stock in a transaction exempt from the registration requirements of the Securities Act. Unless otherwise indicated in the footnotes below, we believe that (1) the Selling Stockholder is not a broker-dealer or affiliate of a broker-dealer, (2) the Selling Stockholder does not have any direct or indirect agreements or understandings with any person to distribute its Shares, and (3) the Selling Stockholder has sole voting and investment power with respect to all shares beneficially owned, subject to applicable community property laws. To the extent the Selling Stockholder is, or is affiliated with, a broker-dealer, it could be deemed to be, under SEC Staff interpretations, an “underwriter” within the meaning of the Securities Act. Information about the Selling Stockholder may change over time. Any changed information will be set forth in supplements to this prospectus, if required.

The following table sets forth information with respect to the beneficial ownership of our Common Stock held, as of November 30, 2021, by the Selling Stockholder and the number of Shares being offered hereby and information with respect to shares to be beneficially owned by the Selling Stockholder after completion of this offering.

If the Selling Stockholder effects such transactions by selling shares of Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the Selling Stockholder or commissions from purchasers of the shares of Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of Common Stock or otherwise, the Selling Stockholder, may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The Selling Stockholder may also sell shares of Common Stock short and deliver shares of Common Stock covered by this prospectus to close out short positions

and to return borrowed shares in connection with such short sales. The Selling Stockholder may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares.

The Selling Stockholder also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Stockholder and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the Selling Stockholder and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.

Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. The aggregate proceeds to the Selling Stockholder from the sale of the Common Stock offered will be the purchase price of the Common Stock less discounts or commissions, if any. The Selling Stockholder reserves the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of Common Stock to be made directly or through agents. There can be no assurance that the Selling Stockholder will sell any or all of the shares of Common Stock registered pursuant to the registration statement of which this prospectus forms a part.

Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

We will pay all expenses of the registration of the shares of Common Stock, including, without limitation, SEC filing fees and expenses of compliance with state securities or debt securities“Blue Sky” laws; provided, however, that the Selling Stockholder will pay all underwriting fees, discounts or commissions attributable to the sale of the Shares or any legal fees and expenses of counsel to the Selling Stockholder, if any.

    Outstanding Convertible Note

    As of November 30, 2021, we had outstanding a convertible promissory note in an aggregate principal amount of $22,000,000 (the “Convertible Note”). The Convertible Note will bear no interest until the November 23, 2022 and will thereafter bear interest at a rate of 5% per annum, and mature on November 23, 2024 (the “Maturity Date”). At any time following August 23, 2022, from time to time and before the Maturity Date, the holder of the Convertible Note (the “Noteholder”) will have the option to convert any portion of the then-outstanding principal amount of the Convertible Note into shares of commonCommon Stock at a price per share of $6.00, subject to adjustment for stock forsplits, reverse stock splits, stock dividends and similar transactions (the “Conversion Price”). At any time prior August 23, 2022, we will have the right to prepay, in whole or in part (exercisable by us at any time or from time to time during such period), up to an aggregate of $14,666,667 of the outstanding principal amount of the Convertible Note with no penalty. If we do not prepay any amounts of the Convertible Note prior to August 23, 2022 then, commencing August 23, 2022, we will have the right to prepay, in whole or in part (exercisable by us at any time or from time to time prior to the Maturity Date), up to the full remaining principal amount of the Convertible Note with no penalty; however, if we exercise such prepayment right, the Noteholder will have the option to convert up to thirty-three and one-third percent (331/3%) of the amount that we elect to prepay at the Conversion Price. If we prepay any amounts of the Convertible Note prior to August 23, 2022 then, commencing November 23, 2022, we will not have the right to prepay any amounts of the Convertible Note between August 23, 2022 to November 23, 2022 and, commencing November 23, 2022, we will have the right to prepay, in whole or in part (exercisable us at any time or from time to time prior to the Maturity Date) up to the full remaining principal amount of the Convertible Note with no penalty; however, if we exercise such prepayment right, the Noteholder will have the option to convert up to thirty-three and one-third percent (331/3%) of the amount that we elect to prepay at the Conversion Price. The Convertible Note is secured by a periodfirst priority lien on our assets and properties.

    Subject to certain exceptions, we will be required to direct proceeds from any subsequent debt financings (including subordinated debt, convertible debt or mandatorily redeemable preferred stock but other than purchase money debt or capital lease obligations or other indebtedness incurred in the ordinary course of 30business) to repay the Convertible Note, unless waived by the Noteholder in advance.

     Beginning on November 23, 2022, the Convertible Note will amortize in twenty-four monthly installments equal to the quotient of (i) the then-outstanding principal amount of the Convertible Note, divided by (ii) the number of months remaining until the Maturity Date. All amortization payments will be payable, at our sole option, in cash, shares of Common Stock or a combination of both. In addition, commencing on the last business day of the first month following November 23, 2022, we will pay, on a monthly basis, all interest that has accrued and remains unpaid on the then-outstanding principal amount of the Convertible Note. Any portion of an amortization payment or interest payment that is paid in shares of Common Stock will be priced at 90% of the average of the five lowest daily volume weighted average prices of the Common Stock during the 20 trading days fromprior to the effective date of issuance of the Resale Registration Statement (other than this universal “shelf” registration statement on Form S-3 provided we cannot sell any shares pursuant to this shelf registration statement until 30 daysshares.

    Anti-Takeover Effects of Nevada Law and Provisions of our Amended and Restated Articles of Incorporation, as amended, and Amended and Restated Bylaws,


    as amended

    Certain provisions of Nevada law and our Amended and Restated Articles of Incorporation, as amended, and restated articles of incorporationAmended and fourthRestated Bylaws, as amended, and restated bylaws could make the following more difficult:

    acquisition of us by means of a tender offer;
    acquisition of us by means of a proxy contest or otherwise; or
    removal of our incumbent officers and directors.

    • acquisition of us by means of a tender offer;
    • acquisition of us by means of a proxy contest or otherwise; or
    • removal of our incumbent officers and directors.

    These provisions, summarized below, could have the effect of discouraging certain types of coercive takeover practices and inadequate takeover bids. These provisions may also encourage persons seeking to acquire control of us to first negotiate with our board of directors.


    Classified Board. Our amendedAmended and restated articlesRestated Articles of incorporationIncorporation, as amended, provide that our board of directors is to be divided into three classes, as nearly equal in number as possible, with directors in each class serving three-year terms. This provision may have the effect of delaying or discouraging an acquisition of us or a change in our management.


    Filling Vacancies. Our Amended and Restated Articles of Incorporation, as amended, provide that newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the our board of directors resulting from death, resignation, retirement, disqualification, removal from office or other cause shall, unless otherwise provided by law or resolution of our board of directors, be filled only by a majority of the directors then in office, though less than a quorum. The directors so chosen shall hold office for a term expiring at the annual meeting of stockholders at which the term of office of the class to which they have been chosen expires.

    Removal. The Nevada Revised Statutes (“NRS”) provide that any director may be removed from our board of directors by the vote or written consent of stockholders representing not less than two-thirds of the voting power of the issued and outstanding shares entitled to vote, and this standard is also reflected in our Amended and Restated Articles of Incorporation, as amended, and our Amended and Restated Bylaws, as amended.

    Requirements for Advance Notification of Stockholder Nominations and Proposals. Our amendedAmended and restated bylawsRestated Bylaws, as amended, establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors.


    Special Meetings of the Stockholders. Our amendedAmended and restated bylawsRestated Bylaws, as amended, provide that special meetings of the stockholders may be called by our Chairchair of the Boardour board of directors or our President, or by our board of directors acting pursuant to a resolution adopted by the total number of authorized directors, whether or not there exist any vacancies in previously authorized directorships.


    No Cumulative Voting. Our Amended and Restated Articles of Incorporation, as amended, and restated articles of incorporationAmended and Restated Bylaws, as amended, and restated bylaws do not provide for cumulative voting in the election of directors.


    Undesignated Preferred Stock. The authorization of undesignated preferred stock in our amendedAmended and restated articlesRestated Articles of incorporationIncorporation, as amended, makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of theour company. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company.

    Amendment of Charter Provisions. The amendment of any of the company.


    above provisions set forth in our Amended and Restated Articles of Incorporation, as amended, except for the provision making it possible for our board of directors to issue undesignated preferred stock, would require approval by a stockholder vote by the holders of at least 66-2/3% of the voting power of all the then-outstanding shares of our capital stock of entitled to vote generally in the election of directors.

    In addition, the Nevada Revised Statutes containNRS contains provisions governing the acquisition of a controlling interest in certain Nevada corporations. Nevada’s “acquisition of controlling interest” statutes (NRS 78.378 through 78.3793, inclusive) contain provisions



    governing the acquisition of a controlling interest in certain Nevada corporations. These “control share” laws provide generally that any person that acquires a “controlling interest” in certain Nevada corporations may be denied voting rights, unless a majority of the disinterested stockholders of the corporation elects to restore such voting rights. These laws will apply to us as of a particular date if we were to have 200 or more stockholders of record (at least 100 of whom have addresses in Nevada appearing on our stock ledger)ledger at all times during the 90 days immediately preceding that date) and do business in the State of Nevada directly or through an affiliated corporation, unless our articles of incorporation or bylaws in effect on the tenth day after the acquisition of a controlling interest provide otherwise. These laws provide that a person acquires a “controlling interest” whenever a person acquires shares of a subject corporation that, but for the application of these provisions of the NRS, would enable that person to exercise (1) one-fifth or more, but less than one-third, (2) one-third or more, but less than a majority or (3) a majority or more, of all of the voting power of the corporation in the election of directors. Once an acquirer crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold and within the 90 days immediately preceding the date when the acquiring person acquired or offered to acquire a controlling interest become “control shares” to which the voting restrictions described above apply. These laws may have a chilling effect on certain transactions if our Amended and Restated Articles of Incorporation, as amended, or Amended and restated articles of incorporation orRestated Bylaws, as amended, and restated bylaws are not amended to provide that these provisions do not apply to us or to an acquisition of a controlling interest, or if our disinterested stockholders do not confer voting rights in the control shares.

    Nevada’s “combinations with interested stockholders” statutes (NRS 78.411 through 78.444, inclusive) provide that specified types of business “combinations” between certain Nevada corporations and any person deemed to be an “interested stockholder” of the corporation are prohibited for two years after such person first becomes an “interested stockholder” unless the corporation’s board of directors approves the combination (or the transaction by which such person becomes an “interested stockholder”) in advance, or unless the combination is approved by the board of directors and sixty percent of the corporation’s voting power not beneficially owned by the interested stockholder, its affiliates and associates. Furthermore, in the absence of prior approval certain restrictions may apply even after such two-year period. For purposes of these statutes, an “interested stockholder” is any person who is (1) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (2) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then-outstanding shares of the corporation. The definition of the term “combination” is sufficiently broad to cover most significant transactions between a corporation and an “interested stockholder”. These laws generally apply to Nevada corporations with 200 or more stockholders of record. However, a Nevada corporation may elect in its articles of incorporation not to be governed by these particular laws, but if such election is not made in the corporation’s original articles of incorporation, the amendment (1) must be approved by the affirmative vote of the holders of stock representing a majority of the outstanding voting power of the corporation not beneficially owned by interested stockholders or their affiliates and associates, and (2) is not effective until 18 months after the vote approving the amendment and does not apply to any combination with a person who first became an interested stockholder on or before the effective date of the amendment. We have not made such an election in our original articles of incorporation or in our Amended and Restated Articles of Incorporation, as amended, and restated articleswe have not amended our Amended and Restated Articles of incorporation.

    Covenants

    We will set forth in the applicable prospectus supplement any restrictive covenants applicable to any issue of debt securities (Article IV).

    No Protection in the Event of a Change of Control

    LEGAL MATTERS

    Unless we state otherwise indicated in the applicable prospectus supplement, the debt securities will not contain any provisions that may afford holdersvalidity of the debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) that could adversely affect holders of debt securities.

    Consolidation, Merger and Sale of Assets

    We may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to, any person (a “successor person”) unless:
    we are the surviving corporation or the successor person (if other than Apricus Bio) is a corporation organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture;
    immediately after giving effect to the transaction, no Default or Event of Default, shall have occurred and be continuing; and
    certain other conditions are met.

    Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or transfer all or part of its properties to us (Section 5.1).

    Events of Default

    “Event of Default” means with respect to any series of debt securities, any of the following:
    default in the payment of any interest upon any debt security of that series when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of the payment is deposited by us with the trustee or with a paying agent prior to the expiration of the 30-day period);
    default in the payment of principal of any debt security of that series at its maturity;
    default in the performance or breach of any other covenant or warranty by us in the indenture or any debt security (other than a covenant or warranty that has been included in the indenture solely for the benefit of a series of debt securities other than that series), which default continues uncured for a period of 60 days after we receive written notice from the trustee or Apricus and the trustee receive written notice from the holders of not less than 25% in principal amount of the outstanding debt securities of that series as provided in the indenture;
    certain voluntary or involuntary events of bankruptcy, insolvency or reorganization of Apricus; or
    any other Event of Default provided with respect to debt securities of that series that is described in the applicable prospectus supplement (Section 6.1).

    No Event of Default with respect to a particular series of debt securities (except as to certain events of bankruptcy, insolvency or reorganization) necessarily constitutes an Event of Default with respect to any other series of debt securities (Section 6.1). The occurrence of certain Events of Default or an acceleration under the indenture may constitute an event of default under certain indebtedness of ours or our subsidiaries outstanding from time to time.

    We will provide the trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action we are taking or propose to take in respect thereof (Section 6.1).



    If an Event of Default with respect to debt securities of any series at the time outstanding occurs and is continuing, then the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may, by a notice in writing to us (and to the trustee if given by the holders), declare to be due and payable immediately the principal of (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) and accrued and unpaid interest, if any, on all debt securities of that series. In the case of an Event of Default resulting from certain events of bankruptcy, insolvency or reorganization, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding debt securities. At any time after a declaration of acceleration with respect to debt securities of any series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all Events of Default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series, have been cured or waived as provided in the indenture (Section 6.2). We refer you to the prospectus supplement relating to any series of debt securities that are discount securities for the particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an Event of Default.

    The indenture provides that the trustee may refuse to perform any duty or exercise any of its rights or powers under the indenture, unless the trustee receives indemnity satisfactory to it against any cost, liability or expense that might be incurred by it in performing such duty or exercising such right or power (Section 7.1(e)). Subject to certain rights of the trustee, 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 (Section 6.12).

    No holder of any debt security of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:
    that holder has previously given to the trustee written notice of a continuing Event of Default with respect to debt securities of that series; and
    the holders of not less than 25% in principal amount of the outstanding debt securities of that series have made written request, and offered indemnity or security satisfactory to the trustee, to the trustee to institute the proceeding as trustee, and the trustee has not received from the holders of not less than a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days (Section 6.7).

    Notwithstanding any other provision in the indenture, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, and premium and any interest on, that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment (Section 6.8).

    The indenture requires us, within 120 days after the end of our fiscal year, to furnish to the trustee a statement as to compliance with the indenture (Section 4.3). If a Default or Event of Default occurs and is continuing with respect to the securities of any series and if it is known to a responsible officer of the trustee, the trustee shall mail to each holder of the securities of that series notice of a Default or Event of Default within 90 days after it occurs or, if later, after a responsible officer of the trustee has knowledge of such Default or Event of Default. The indenture provides that the trustee may withhold notice to the holders of debt securities of any series of any Default or Event of Default (except in payment on any debt securities of that series) with respect to debt securities of that series if the trustee determines in good faith that withholding notice is in the interest of the holders of those debt securities (Section 7.5).

    Modification and Waiver

    We and the trustee may modify, amend or supplement the indenture or the debt securities of any series without the consent of any holder of any debt security:
    to cure any ambiguity, defect or inconsistency;


    to comply with covenants in the indenture described above under the heading “Consolidation, Merger and Sale of Assets;”
    to provide for uncertificated securities in addition to or in place of certificated securities;
    to add guarantees with respect to debt securities of any series or secure debt securities of any series;
    to surrender any of our rights or powers under the indenture;
    to add covenants or Events of Default for the benefit of the holders of debt securities of any series;
    to comply with the applicable procedures of the applicable depositary;
    to make any change that does not adversely affect the rights of any holder of debt securities;
    to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;
    to effect the appointment of a successor trustee with respect to the debt securities of any series and to add to or change any of the provisions of the indenture to provide for or facilitate administration by more than one trustee; or
    to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act (Section 9.1).

    We may also modify and amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments. We may not make any modification or amendment without the consent of the holders of each affected debt security then outstanding if that amendment will:
    reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;
    reduce the rate of or extend the time for payment of interest (including default interest) on any debt security;
    reduce the principal of or premium on or change the fixed maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation with respect to any series of debt securities;
    reduce the principal amount of discount securities payable upon acceleration of maturity;
    waive a Default or Event of Default in the payment of the principal of, or premium or interest on, any debt security (except a rescission of acceleration of the debt securities of any series by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);
    make the principal of, or premium or interest on, any debt security payable in currency other than that stated in the debt security;
    make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, and premium and interest on, those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or
    waive a redemption payment with respect to any debt security (Section 9.3).

    Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive our compliance with provisions of the indenture (Section 9.2). The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all the debt securities of such series waive any past default under the indenture with respect to that series and its consequences, except a default in the payment of the principal of, or any interest on, any debt security of that series; provided,


    however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration (Section 6.13).

    Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

    Legal Defeasance. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, we may be discharged from any and all obligations in respect of the debt securities of any series (subject to certain exceptions). We will be so discharged upon the deposit with the trustee, in trust, of money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money or U.S. government obligations in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on, and any mandatory sinking fund payments in respect of, the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities.

    This discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel stating that we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred (Section 8.3).

    Defeasance of Certain Covenants. The indenture provides that, unless otherwise provided by the terms of the applicable series of debt securities, upon compliance with certain conditions:
    we may omit to comply with the covenant described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants that may be set forth in the applicable prospectus supplement; and
    any omission to comply with those covenants will not constitute a Default or an Event of Default with respect to the debt securities of that series (“covenant defeasance”).

    The conditions include: 
    depositing with the trustee money and/or U.S. government obligations or, in the case of debt securities denominated in a single currency other than U.S. dollars, government obligations of the government that issued or caused to be issued such currency, that, through the payment of interest and principal in accordance with their terms, will provide money in an amount sufficient in the opinion of a nationally recognized firm of independent public accountants or investment bank to pay and discharge each installment of principal of, premium and interest on, and any mandatory sinking fund payments in respect of, the debt securities of that series on the stated maturity of those payments in accordance with the terms of the indenture and those debt securities; and
    delivering to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling or, since the date of execution

    of the indenture, there has been a change in the applicable United States federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit and related covenant defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit and related covenant defeasance had not occurred (Section 8.4).

    No Personal Liability of Directors, Officers, Employees or Stockholders

    None of our past, present or future directors, officers, employees or stockholders, as such, will have any liability for any of our obligations under the debt securities or the indenture or for any claim based on, or in respect or by reason of, such obligations or their creation. By accepting a debt security, each holder waives and releases all such liability. This waiver and release is part of the consideration for the issue of the debt securities. However, this waiver and release may not be effective to waive liabilities under U.S. federal securities laws, and it is the view of the SEC that such a waiver is against public policy.



    Governing Law

    The indenture and the debt securities, including any claim or controversy arising out of or relating to the indenture or the debt securities, will be governed by the laws of the State of New York (Section 10.10).

    The indenture will provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the indenture, the debt securities or the transactions contemplated thereby.

    The indenture will provide that any legal suit, action or proceeding arising out of or based upon the indenture or the transactions contemplated thereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the City of New York, and we, the trustee and the holder of the debt securities (by their acceptance of the debt securities) irrevocably submit to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The indenture will further provide that service of any process, summons, notice or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in the indenture will be effective service of process for any suit, action or other proceeding brought in any such court. The indenture will further provide that we, the trustee and the holders of the debt securities (by their acceptance of the debt securities) irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the courts specified above and irrevocably and unconditionally waive and agree not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum.

    DTC has advised us that it is: 
    a limited-purpose trust company organized under the New York Banking Law;
    a “banking organization” within the meaning of the New York Banking Law;
    a member of the Federal Reserve System;


    a “clearing corporation” within the meaning of the New York Uniform Commercial Code; and
    a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

    DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. “Direct participants” in DTC include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others, which we sometimes refer to as indirect participants, that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

    Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of the actual purchaser of a security, which we sometimes refer to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners of securities will not receive written confirmation from DTC of their purchases. However, beneficial owners are expected to receive written confirmations providing details of their transactions, as well as periodic statements of their holdings, from the direct or indirect participants through which they purchased securities. Transfers of ownership interests in global securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the global securities, except under the limited circumstances described below.

    To facilitate subsequent transfers, all global securities deposited by direct participants with DTC will be registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other nominee will not change the beneficial ownership of the securities. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants are responsible for keeping account of their holdings on behalf of their customers.

    So long as the securities are in book-entry form, you will receive payments and may transfer securities only through the facilities of the depositary and its direct and indirect participants. We will maintain an office or agency in the location specified in the prospectus supplement for the applicable securities, where notices and demands in respect of the securities and the indenture may be delivered to us and where certificated securities may be surrendered for payment, registration of transfer or exchange.

    Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

    Redemption notices will be sent to DTC. If less than all of the securities of a particular series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the securities of such series to be redeemed.

    Neither DTC nor Cede & Co. (or such other DTC nominee) will consent or vote with respect to the securities. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those direct participants to whose accounts the securities of such series are credited on the record date, identified in a listing attached to the omnibus proxy.

    So long as securities are in book-entry form, we will make payments on those securities to the depositary or its nominee, as the registered owner of such securities, by wire transfer of immediately available funds. If securities are issued in definitive certificated form under the limited circumstances described below, we will have the option of making payments by check mailed to the addresses of the persons entitled to payment or by wire transfer to bank accounts in the United States designated in writing to the applicable trustee or other designated party at least 15 days before the applicable payment date by the persons entitled to payment, unless a shorter period is satisfactory to the applicable trustee or other designated party.

    Redemption proceeds, distributions and dividend payments on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payment date in accordance with their respective holdings shown on DTC records. Payments by participants to beneficial owners will be governed by standing instructions and customary


    practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of DTC or us, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility, disbursement of payments to direct participants is the responsibility of DTC, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

    Except under the limited circumstances described below, purchasers of securities will not be entitled to have securities registered in their names and will not receive physical delivery of securities. Accordingly, each beneficial owner must rely on the procedures of DTC and its participants to exercise any rights under the securities and the indenture.

    The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. Those laws may impair the ability to transfer or pledge beneficial interests in securities.

    DTC may discontinue providing its services as securities depositary with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depositary is not obtained, securities certificates are required to be printed and delivered.
    As noted above, beneficial owners of a particular series of securities generally will not receive certificates representing their ownership interests in those securities. However, if: 
    DTC notifies us that it is unwilling or unable to continue as a depositary for the global security or securities representing such series of securities or if DTC ceases to be a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor depositary is not appointed within 90 days of the notification to us or of our becoming aware of DTC’s ceasing to be so registered, as the case may be;
    we determine, in our sole discretion, not to have such securities represented by one or more global securities; or
    an Event of Default has occurred and is continuing with respect to such series of securities,

    we will prepare and deliver certificates for such securities in exchange for beneficial interests in the global securities. Any beneficial interest in a global security that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for securities in definitive certificated form registered in the names that the depositary directs. It is expected that these directions will be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in the global securities.

    We have obtained the information in this section and elsewhere in this prospectus concerning DTC and DTC’s book-entry system from sources that are believed to be reliable, but we take no responsibility for the accuracy of this information.

    PLAN OF DISTRIBUTION

    We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods or through underwriters or dealers, through agents and/or directly to one or more purchasers. The securities may be distributed 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.

    Each time that we sell securities covered by this prospectus, we will provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms and conditions of the offering of such securities, including the offering price of the securities and the proceeds to us, if applicable.



    Offers to purchase the securities beingCommon Stock offered by this prospectus, may be solicited directly. Agents may also be designated to solicit offers to purchase the securities from time to time. Any agent involved in the offer or sale of our securities will be identified in a prospectus supplement.

    If a dealer is utilized in the sale of the securities being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

    If an underwriter is utilized in the sale of the securities being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be provided in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer.

    Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealerssupplement thereto, will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

    Any common stock or preferred stock will be listed on the Nasdaq Capital Market, but any other securities may or may not be listed on a national securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

    If indicated in the applicable prospectus supplement, underwriters or other persons acting as agents may be authorized to solicit offers by institutions or other suitable purchasers to purchase the securities at the public offering price set forth in the prospectus supplement, pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. These purchasers may include, among others, commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. Delayed delivery contracts will be subject to the condition that the purchase of the securities covered by the delayed delivery contracts will not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which the purchaser is subject. The underwriters and agents will not have any responsibility with respect to the validity or performance of these contracts.

    We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

    The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.



    In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc., 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 proceeds of the offering.

    The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

    DISCLOSURE OF CERTAINCOMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

    Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and persons controlling us pursuant to the provisions described in Item 15 of the registration statement of which this prospectus forms a part or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than our payment of expenses incurred or paid by our directors, officers, or controlling persons in the successful defense of any action, suit, or proceeding) is asserted by our directors, officers, or controlling persons in connection with the Common Stock being registered, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by us is against public policy as expressed in the Securities Act and will be governed by the final adjudication of the issue.

However, Nevada Revised Statutes Section 78.138 currently provides that, except as otherwise provided in the Nevada Revised Statutes, a director or officer shall not be individually liable to usthe Registrant or ourits stockholders or creditors for any damages as a result of any act or failure to act in his or her capacity as a director or officer unless it is proven that (i) the presumption established by Nevada Revised Statutes 78.138(3) has been rebutted, (ii) the director’s or officer’s acts or omissions constituted a breach of his or her fiduciary duties as a director or officer, and (ii)(iii) such breach involved intentional misconduct, fraud or a knowing violation of the law.

No such indemnification shall be made to or on behalf of any such director or officer if a final adjudication establishes that his or her acts or omissions involved intentional misconduct, fraud or a knowing violation of law and was material to the cause of action, or for any expenses of such director or officer incurred in his or her capacity as a stockholder. Our FourthThe Amended and Restated Bylaws, as amended, also require that the expenses of such directors and officers must be paid by the corporationRegistrant (or through insurance maintained, or other financial arrangements made, by the corporation)Registrant) as such expenses are incurred and in advance of the final disposition of such action, suit or proceeding, upon receipt of an undertaking by or on behalf of such director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he or she is not entitled to be indemnified by the corporation.Registrant. Any indemnification of directors and officers under our Fourththe Amended and Restated Bylaws, as amended, shall inure to the benefit of their respective heirs, executors and administrators.

    Section 78.7502 of the Nevada Revised Statutes permits a corporation to indemnify, pursuant to that statutory provision, a present or former director, officer, employee or agent of the corporation, or of another entity or enterprise for which such person is or was serving in such capacity at the request of the corporation, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, except an action by or in the right of the corporation, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection therewith, arising by reason of such person’s service in such capacity if such person (i) is not liable pursuant to Section 78.138 of the Nevada Revised Statutes, or (ii) acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to a criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of actions brought by or in the right of the corporation, however, no indemnification pursuant to Section 78.7502 of the Nevada Revised Statutes may be made for any claim, issue or matter as to which such person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

    Section 78.751 of the Nevada Revised Statutes permits any

    Any discretionary indemnification underpursuant to Section 78.7502 of the Nevada Revised Statutes, unless ordered by a court or advanced to a director or officer by the corporation in accordance with the Nevada Revised Statutes, tomay be made by a corporation only as authorized in each specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances. Such determination must be made (1) by the stockholders, (2) by the board of directors by majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding, (3) if a majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding so orders, by independent legal counsel in a written opinion, or (4) if a quorum consisting of directors who were not parties to the action, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion.

    We maintain

    Section 78.751 of the Nevada Revised Statutes further provides that indemnification pursuant to Section 78.7502 of the Nevada Revised Statutes does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under our Amended and Restated Articles of Incorporation, as amended, or any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in the person’s official capacity or an action in another capacity while holding office, except that indemnification, unless ordered by a court pursuant to Section 78.7502 of the Nevada Revised Statutes or for the advancement of expenses, may not be made to or on behalf of any director or officer finally adjudged by a court of competent jurisdiction, after exhaustion of any appeals, to be liable for intentional misconduct, fraud or a knowing violation of law, and such misconduct, fraud or violation was material to the cause of action.

    The Registrant maintains a general liability insurance policy that covers certain liabilities of directors and officers of our corporationthe Registrant arising out of claims based on acts or omissions in their capacities as directors or officers.

    (7) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.


    (d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act (the “Act”) in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Act.
