Overview

 

Founded in 2012 by faculty members of the Georgetown University Medical Center, Shuttle Pharmaceuticals is a discovery and development stage specialty pharmaceutical company focused on improving the outcomes of cancer patients treated with radiation therapy (RT). Our mission is to improve the lives of cancer patients by developing therapies that are designed to maximize the effectiveness of RT while limiting the late effects of radiation in cancer treatment. Although RT is a proven modality for treating cancers, by developing radiation sensitizers, we aim to increase cancer cure rates, prolong patient survival and improve quality of life when used as a primary treatment, or in combination with surgery, chemotherapy and immunotherapy. We currently have no FDA approved products and we have not yet applied for a new drug application. To date, we have been funded by investments from private investors and government contracts obtained from the National Institutes of Health (NIH) for performing research. We have no product revenue and our independent auditors, in their report dated June 3, 2022, expressed doubt about our ability to continue as a going concern.

 

Historically, the major advances in radiation oncology have focused on improving technology to increase the amount of radiation that can be administered to a tumor without damaging adjacent, normal tissues. Examples of other such technologies include intensity modulated radiation therapy (IMRT), stereotactic body radiation therapy (SBRT), stereotactic radiosurgery (SRS) and proton therapy – the backbones of state-of-the-art RT. All offer improvements in physical radiation dose shaping. The basic principle underlying the effectiveness of RT for curing cancers lies in the differential cancer cell kill achieved in tumors, as compared to the effects of RT on the normal surrounding tissues, which is achieved by delivery of highly conformal RT doses – in other words, delivery of high-dose to volumes that are shaped to conform to the target cancers while minimizing the dose to surrounding normal tissues. The treated volumes frequently include sensitive normal tissues, thereby limiting the magnitudes of the prescribed RT doses. We suggest that technological innovations to define tumor volumes and shape radiation delivery have reached an effectiveness plateau and that further improvements in RT outcomes will require pharmacological and immunological approaches to sensitize cancers, protect normal tissues and engage the immune system.

 

At present, the drugs being used for sensitizing cancers to RT are chemotherapeutic agents possessing radiation sensitizing properties as secondary effects. With the exception of Cetuximab a growth factor targeting monoclonal antibody biologic, all other drugs used as radiation sensitizers are used “off-label” to address the clinical need for radiation sensitizers. For example, certain chemotherapeutic agents, such as 5-fluorouracil, capecitabine and cis-platinum, are approved as single agents for cancer treatment, but are used “off-label” as radiation sensitizers in combination with RT. Treatments with such agents are associated with inherent toxicities associated with the drug’s primary, single-agent mechanisms of action.

 

Shuttle Pharma’s platform of sensitizers offers a pipeline of product candidates designed to address the urgent clinical need and the current limitations of using “off-label” drugs with potential new sensitizer agents. Our pipeline includes Ropidoxuridine, our lead clinical sensitizer drug candidate, to sensitize rapidly growing cancer cells and selective histone deacetylase (HDAC) inhibitors to sensitize cancer cells and stimulate the immune system. Our novel technologies will be tested in combinations with radiation therapies (conventional X-ray and proton radiation therapies) and in combinations with immune-therapies. To date, Ropidoxuridine has completed a Phase I clinical trial. Our HDAC inhibitor platform drug candidates have been tested in preclinical models of solid tumor cancers. Ropidoxuridine and the selective HDAC6 inhibitor SP-2-225 are the clinical and preclinical candidate drug products we propose to develop using funding from this offering.

 

Our intellectual property for Ropidoxuridine includes novel formulations that show improved drug bioavailability (in a preclinical animal model) and for sensitizing cancers to proton and to conventional radiation therapies. Our HDAC inhibitor intellectual property includes new patent applications and granted patents for composition of matter and methods of use for treating cancers with HDAC inhibitors in combinations with radiation therapy.

 

I-1

 

 

To date, we have obtained funding for our research from private investors and Small Business Innovation Research (“SBIR”) contracts obtained through the National Institutes of Health (“NIH”) to support the development of the radiation sensitizer Ropidoxuridine in a Phase I clinical trial. We have also received awards for Phase I and II SBIR contracts for development of human cell cultures for health disparities studies and predictive biomarkers of radiation late effects through the NIH’s National Cancer Institute. The completed Phase I and II funded discovery work performed to establish “Cell-based Models for Prostate Cancer Health Disparity Research” and to develop “Predictive Biomarkers of Prostate Cancer Sensitivity for Radiation Late Effects” enables Shuttle Pharma to apply for NIH SBIR Phase II funding to develop these products for advancing basic science and clinical research.

 

Our Product Candidates

 

The U.S. Food and Drug Administration (the “FDA”) considers new molecular entities as drugs that use new and unique mechanisms of action for treating medical conditions. Our clinical stage agent, Ropidoxuridine (IPdR), increases DNA double strand breaks following radiation exposure and our inhibitors of histone deacetylases (HDACs) stimulate the immune system to produce T-lymphocytes targeting cancer cells.

 

Our objective is to improve the outcomes of cancer treatment through RT while reducing its side effects by:

 

  Sensitizing growing cancer cells to render them more susceptible to the effects of RT;
     
  Activating the DNA damage response pathway to protect normal cells located near cancers; and
     
  Activating the immune response to antigens present on irradiated and un-irradiated cancer cells.

 

To our knowledge, no drug utilizing the mechanisms of our candidate small molecule drugs has received FDA approval as a radiation sensitizer. We have developed, to clinical stage, the small molecule strategies to sensitize growing cancer cells in tumors to conventional RT and to large fraction radiation therapy. The pre-clinical technology, HDAC inhibitor platform, is designed to target cancer cells while protecting healthy tissue/normal cells, thus enhancing the candidate radiation sensitizer product pipeline. The selective HDAC6 inhibitor (SP-2-225), discovered and developed by our scientists, has inhibited the growth of melanoma tumors and breast cancers in animal models by an immune stimulating mechanism.

 

We are focused on developing a clinical stage product candidate (Ropidoxuridine) and a pre-clinical product candidate, selective HDAC6 inhibitor (SP-2-225). We propose to develop these drug candidates as illustrated below:

 

Overview of Radiation Sensitizer Development

 

 

Ropidoxuridine, the clinical stage molecule, sensitizes rapidly growing cancers to radiation therapy by increasing reactive free radicals that increase DNA strand breaks. Ropidoxuridine development for treating glioblastoma will require Phase II clinical testing for use in treating brain tumors. The selective HDAC6 inhibitor, SP-2-225, a pre-clinical stage molecule, activates the innate immune system to target irradiated tumor cells by immune mechanisms.

Ropidoxuridine (IPdR)

 

Ropidoxuridine (IPdR) is an orally available halogenated pyrimidine (5-iodo-2-pyrimidinone-2-deoxyribose) with strong cancer radiation sensitizing properties. As a prodrug that does not become an active drug until after it is metabolized, IPdR is absorbed and metabolized to IUdR by enzymes in the liver and in cancer cells. IUdR, a halogenated pyrimidine, is incorporated into DNA by rapidly growing cancer cells. Cells that incorporate IUdR into their DNA then become more sensitive to the effects of RT. The Phase I clinical trial of Ropidoxuridine and RT, supported by an NIH SBIR contract to Shuttle Pharma, was sub-contracted to the Brown University Oncology Group (BrUOG) at the LifeSpan/Rhode Island Hospital. This Phase I clinical trial has been completed and the results were initially reported by the sub-contractor at the 30th EORTC-NCI-AACR Symposium in November 2018 and published in the medical journal Clinical Cancer Research in 2019. A maximum tolerated dose (MTD) of 1200 mg/day for 28 days was established for use in combination with radiation therapy to achieve therapeutic blood levels of IUdR.

 

The reported Phase I clinical trial of Ropidoxuridine in combination with RT provides the foundation for proposed Phase II clinical trials to establish the data necessary for the FDA to determine efficacy in treating brain tumors, sarcomas and pancreatic cancers, diseases that offer potential for orphan designations. The FDA granted approval of our application for orphan-drug designation for IPdR for the treatment of glioblastoma. Orphan designation protects the marketing position of Ropidoxuridine for up to seven years after marketing approval is received from the FDA. This approval integrates well into the overall intellectual property strategy for Ropidoxuridine which includes filed patent applications for “Method and Compositions for Cancer Therapies that Include Delivery of Halogenated Thymidines and Thymidine Phosphorylase Inhibitors in Combination with Radiation.” We believe that we are positioned to initiate Phase II clinical studies with Ropidoxuridine and RT in 2023.

 

Extended Bio-availability Ropidoxuridine (IPdR/TPI)

 

Ropidoxuridine and Tipiracil (IPdR/TPI) is a new combination drug formulation designed to increase the bio-availability and incorporation of IUdR into DNA. Shuttle Pharma’s preclinical studies of the combination of IPdR/TPI have shown up to 10-fold greater bioavailability of the active metabolite (IUdR) as compared to IPdR administered alone in controls. We have filed an application under the Patent Cooperation Treaty (or PCT) for the intellectual property. This new formulation will be tested in a Phase I clinical trial as a sensitizer of rectal cancers. Another nucleoside analogue, Trifluridine has been formulated in combination with Tipiracil (TAS-102) to enhance drug uptake by colon cancer cells to prolong survival in patients treated for metastatic colorectal cancers, as has been reported in the New England Journal of Medicine (N Engl J Med. 2015; 372:1909-1919). We anticipate testing for uptake of IPdR by colorectal cancer cells following administration of the IPdR/TPI drug formulation.

 

Proton radiation therapy is an advanced form of radiation therapy using charged proton particles (p+). Proton RT differs from conventional RT in that the radiation is delivered by a beam of protons to precisely target tumors and, due to the favorable physics of energy deposition by proton particles, there is no exit beam, resulting in less radiation to surrounding healthy tissues. The use of Proton RT is expanding rapidly in the U.S. and worldwide. According to the National Association of Proton Therapy, more than 30 facilities are currently in operation in the U.S. and an additional 30 facilities are planned for installation over the next five years. (See www.proton-therapy.org.) Much attention has been paid to proton therapy in the popular press, promoting its advantages, as well as addressing the increased health care costs. The role of a sensitizer that offers proton radiation sensitization presents an opportunity to enhance the value of proton radiation therapy as a cancer treatment modality. We believe the development of a proton therapy targeted radiation sensitizer, such as IPdR/TPI, is timely and consistent with current market needs to advance protons as a therapeutic modality.

 

We intend to perform clinical studies to support the development of the IPdR/TPI combination to advance this drug candidate with proton RT. The addressable market includes diseases such as brain tumors, cancers of the head and neck, GI cancers and lung cancers.

 

Selective HDAC Inhibitors

 

The roles of acetylation in the epigenetic regulation of chromatin structure and gene expression rests on the balance of activities of histone acetyltransferases (HATs) and histone deacetylases (HDACs). Increased acetylation of histones leads to changes in chromatin structure and accessibility for key cellular proteins to specific target sites. Acetylations of non-histone proteins also modulates their enzymatic activities. We have discovered novel HDAC inhibitor molecules and testing in preclinical models has shown cancer radiation sensitizing properties, normal tissue protective properties and selective HDAC6 inhibitory properties. Our HDAC inhibitor platform, described below, will be evaluated in pre-clinical studies of radiation sensitization of solid tumors and activation of the immune response to irradiated cancer cells.

 

I-3

 

 

  SP-1-161 is our candidate lead pre-clinical, pan-HDAC inhibitor that initiates the mutated in ataxia-telangiectasia (ATM) response pathway. ATM is activated by ionizing radiation induced DNA damage. Activated ATM phosphorylates critical factors involved in DNA repair, apoptosis, and cell cycle checkpoint. Phosphorylation of the molecules in these pathways, in turn, activates the cellular functions. ATM also can be activated by HDAC inhibitors and imparts radiation protective properties. Using rational drug design, we discovered HDAC inhibitors and ATM activators capable of radiation sensitizing cancer cells and protecting normal cells. SP-1-161 is our lead candidate radiation sensitizing pan-HDAC inhibitor.
     
  SP-2-225 is our candidate lead selective histone deacetylase inhibitor of HDAC6. HDAC6 is a member of the Class IIb HDAC family. Selective HDAC6 inhibitors are an emerging class of pharmaceuticals due to effects on neurodegenerative diseases, cancers and immunology. Specifically, the potential to affect regulation of the immune system and enhance the immune response to cancers is of significant interest as an adjuvant treatment in combination with radiation therapy. We propose to test our HDAC6 inhibitors for a role in enhancing post-RT immune responses to antigens produced in irradiated cancers for their effects on control of local and metastatic disease.
     
  SP-1-303 is a selective Class I HDAC inhibitor that preferentially affects histone deacetylases HDAC1 and HDAC3 and shows direct and selective cytotoxicity for ER positive and Her2 negative breast cancer cells.

 

Drug Development Projects for Radiation Treatment of Cancers

 

To advance research that is complementary to our radiation sensitizer discovery and development projects, the NIH has awarded SBIR contracts to us to develop reagents for health disparities research and to develop biomarkers of radiation sensitivity for patients treated with radiation therapy. Our scientists have been engaged in developing model human cell systems for testing radiation sensitizers in tissue cultures. This project provides an efficient and low-cost screening technology to provide data for the FDA’s determination of drug efficacy and to identify candidate lead molecules for treating prostate cancers in African-Americans. First developed at Georgetown University, the conditional cellular reprogramming (CRC) technology offers the ability to establish new cell lines from biopsies of cancers. We have obtained a sub-license from Propagenix, Inc. to establish 100 normal and cancer cell lines from prostate biopsy samples for use in screening drug candidates and for health disparities research. A more detailed description of the Propagenix license is set forth on page 60 below.

 

In addition, to identify patients who may be more sensitive to radiation therapy and are at a higher risk to suffer treatment-related complications, collaborative research with Georgetown University has led to discovery of metabolite biomarkers, which are predictive of patient responses to radiation therapy. A patent for the intellectual property has been submitted by Georgetown University with Shuttle Pharma scientist (Scott Grindrod, PhD) as co-inventor. Developmental work in health disparities and predictive biomarker development has been supported by NIH SBIR contracts to Shuttle Pharmaceuticals for the following areas:

 

  Develop prostate cancer cell lines from African-American men with the goal of advancing research to address prostate cancer health disparities (designated SBIR “Topic 352: Cell-Based Models for Prostate Cancer Health Disparity Research- Moonshot Project (Phase II)”); and
     
  Develop predictive biomarkers of prostate patient outcomes following treatment with SBRT (designated SBIR “Topic 345: Predictive Biomarkers for Prostate Cancer Sensitivity for Radiation Late Effects (Phase I and II).”

 

The NIH’s SBIR program is designed to encourage small businesses to engage in Federal Research/Research and Development (“R/R&D”) that has the potential for commercialization. Shuttle Pharma will apply for additional NIH SBIR grants and contracts to fund advancement of these projects.

 

Market Opportunity

 

The American Cancer Society (Cancer Facts & Figures 2020) estimates 1,806,590 new cancer cases and 606,520 cancer deaths each year in the United States and, according to the American Society for Radiation Oncology, more than 50% of patients undergo RT at some point in the treatment of their diseases. RT is used to treat cancers of the lung, breast, brain, esophagus, pancreas, rectum, head and neck, uterus, lymphomas and sarcomas. At present, we are developing drug candidates to address brain, pancreas, rectum, sarcomas and lymphomas, although we may test and seek approval for our drug candidates to treat other cancers in the future.

 

I-4

 

 

Currently, there is only one drug (the monoclonal antibody, Cetuximab) that has received FDA approval for the radiation sensitizer indication. Cetuximab is a recombinant monoclonal antibody that binds to epidermal growth factor receptor (EGFR) and inhibits the binding of epidermal growth factor (EGF). Cetuximab is administered via intravenous infusion and is used as monotherapy or in combination with other chemotherapies or radiation therapy. In clinical trials, cetuximab was associated with serious and fatal infusion reactions, cardiopulmonary arrest or sudden death, and serious dermatologic toxicities, toxicities that have created deterrents to its use as a radiation sensitizer. Present treatment utilizes “off-label” small molecule drugs, which are cytotoxic chemotherapy agents that also sensitize, but do not have radiation sensitization as an FDA approved indication. Moreover, since “off-label” drugs are cytotoxic, they are often associated with intrinsic acute and chronic side effects. Nevertheless, these drugs have shown clinically significant improvements in disease control and survival and are typically included in standard-of-care treatment recommendations for patients with cancers of the head and neck, brain, lung, esophagus, stomach, pancreas, liver, bladder, lymphomas and sarcomas. As a result, we believe that there is a significant market opportunity for our product candidates. Based on cancer incidence data published by the American Cancer Society, we have estimated the numbers of patients presenting with local/regional disease, suitable for treatment with RT.

 

Estimated RT Cases by Disease Site

 

Cancer Type  Cases Diagnosed Annually

Pancreas   57,600    32,832 
Sarcomas   13,130    4,000 
Rectum   43,340    26,437 

 

Annual cancer cases for each disease site are estimated from American Cancer Society Facts & Figures 2020 publication. The fraction of patients optimally receiving RT for each disease site were obtained from published estimates of Delaney G, Jacob S, Featherstone C, Barton M. The role of radiotherapy in cancer treatment: estimating optimal utilization from a review of evidence-based clinical guidelines. Cancer. 2005 Sep 15;104(6):1129-37. doi: 10.1002/cncr.21324. The Estimated RT cases were obtained by multiplying Cases Diagnosed Annually by the fraction receiving RT for optimal utilization.

 

Our Development Strategy

 

Our goal is to maintain and build upon our leadership position in radiation sensitization. We plan to develop Ropidoxuridine and the HDAC6 inhibitor (SP-2-225) and, if approved by the FDA, to commercialize our product candidates for the treatment of cancers. While this process may require years to complete, we believe achieving this goal could result in radiation sensitizer and immunotherapy products for cancer treatment. Key elements of our strategy include:

 

  Capitalize on Ropidoxuridine as an orally available, small molecule radiation sensitizer. To date, there is one drug (Cetuximab) approved by the FDA specifically as a radiation sensitizer. If we are successful in developing Ropidoxuridine to obtain FDA approval, a small molecule sensitizer will be enabled for clinical applications for radiation sensitization.
     
  Expand our leadership position within radiation sensitizers. In addition to our traditional radiation sensitizers, we plan to advance our near-term pipeline to include radiation sensitizers for proton therapy. Proton Therapy is growing worldwide as a form of radiation therapy due to its unique beam shaping characteristics. As a result, this new technology offers a major opportunity for Shuttle Pharma to strive to develop a sensitizer drug for proton therapy sensitization applications.
     
  Execute a disciplined business development strategy to strengthen our portfolio of product candidates. We have built our current product pipeline through in-house development, partnerships with leading academic institutions and through successful in-licensing deals. We will continue to evaluate new in-licensing opportunities and collaboration agreements with leading academic institutions and other biotechnology companies around programs that seek to address areas of high unmet need and for which we believe there is a high probability of clinical success, including programs beyond our target franchise areas and current technology footprint.
     
  Invest in our HDAC platform technology to maximize its utility across cancer therapies. We are initially applying the platform to develop drugs for cancer radiation sensitization and normal tissue radiation protection. In addition, these drugs also affect immune regulatory properties. We intend to invest to investigate other properties of our platform technology.

 

I-5

 

 

  Enter into collaborations to realize the full potential of our platform. The breadth of our HDAC technology platform enables other therapeutic applications, in addition to radiation sensitization and immune therapy. We intend to seek collaborations centered on our platform to maximize applications for our HDAC inhibitor technology.

 

We propose the following clinical development plan to identify, develop and commercialize drugs for use in cancer treatments in combination with RT:

This prospectus relates to the reoffer and resale from time to time of up to 3,000,000 shares of Common Stock issued to the selling shareholders, or underlying equity awards issued to the selling shareholders, under our Equity Incentive Plan. The selling shareholders may sell any, all or none of such shares and we do not know when or in what amount the selling shareholders may sell such shares. The inclusion of such shares in the table below does not necessarily represent a present intention by the selling shareholders to sell any or all such shares. However, for the purposes of the table below, we have assumed that, after the completion of this offering, all Common Stock covered by this prospectus has been sold.

 

The following table sets forth (i) the number of shares of Common Stock beneficially owned by each selling shareholder as of December 12, 2022, (ii) the number of shares to be offered for resale by each selling shareholder and (iii) the number and percentage of shares of Common Stock that each selling shareholder will beneficially own after completion of the offering, assuming that all shares of Common Stock that may be offered for resale are sold and no other shares of Common Stock beneficially owned by the selling shareholders also are sold.

 

Unless otherwise indicated, the address for each of the selling shareholders named below is c/o Shuttle Pharmaceuticals Holdings, Inc., One Research Court, Suite 450, Rockville, Maryland 20850.

PLAN OF DISTRIBUTION

 

In this section of the reoffer prospectus, the term “selling shareholder” means and includes:

 

  the persons identified in the table above as the selling shareholders; and
     
  any of the donees, pledgees, distributees, transferees or other successors in interest of those persons referenced above who may: (a) receive any of the shares of our common stock offered hereby after the date of this reoffer prospectus and (b) offer or sell those shares hereunder.

 

The shares of our common stock offered by this reoffer prospectus may be sold from time to time directly by the selling shareholders. Alternatively, the selling shareholders may from time to time offer such shares through underwriters, brokers, dealers, agents or other intermediaries. The selling shareholders as of the date of this reoffer prospectus have advised us that there were no underwriting or distribution arrangements entered into with respect to the common stock offered hereby. The distribution of the common stock by the selling shareholders may be effected: in one or more transactions that may take place on the Nasdaq Capital Market (including one or more block transaction) through customary brokerage channels, either through brokers acting as agents for the selling shareholders, or through market makers, dealers or underwriters acting as principals who may resell these shares on the Nasdaq Capital Market; in privately-negotiated sales; by a combination of such methods; or by other means. These transactions may be effected at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at other negotiated prices. Usual and customary or specifically negotiated brokerage fees or commissions may be paid by the selling stockholders in connection with sales of our common stock.

 

The selling shareholders may enter into hedging transactions with broker-dealers in connection with distributions of the shares or otherwise. In such transactions, broker-dealers may engage in short sales of the shares of our common stock in the course of hedging the positions they assume with the selling shareholders. The selling shareholders also may sell shares short and redeliver the shares to close out such short positions. The selling shareholders may enter into option or other transactions with broker-dealers which require the delivery to the broker-dealer of shares of our common stock. The broker-dealer may then resell or otherwise transfer such shares of common stock pursuant to this reoffer prospectus.

 

The selling shareholders also may lend or pledge shares of our common stock to a broker-dealer. The broker-dealer may sell the shares of common stock so lent, or upon a default the broker-dealer may sell the pledged shares of common stock pursuant to this reoffer prospectus. Any securities covered by this reoffer prospectus which qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this reoffer prospectus.

 

The selling shareholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their securities. There is no underwriter or coordinating broker acting in connection with the proposed sale of shares of common stock of the selling shareholders.

 

Although the shares of common stock covered by this reoffer prospectus are not currently being underwritten, the selling shareholders or their underwriters, brokers, dealers or other agents or other intermediaries, if any, that may participate with the selling security holders in any offering or distribution of common stock may be deemed “underwriters” within the meaning of the Act and any profits realized or commissions received by them may be deemed underwriting compensation thereunder.

 

Under applicable rules and regulations under the Exchange Act, any person engaged in a distribution of shares of the common stock offered hereby may not simultaneously engage in market making activities with respect to the common stock for a period of up to five days preceding such distribution. The selling shareholders will be subject to the applicable provisions of the Exchange Act and the rules and regulations promulgated thereunder, including without limitation Regulation M, which provisions may limit the timing of purchases and sales by the selling shareholders.

 

In order to comply with certain state securities or blue sky laws and regulations, if applicable, the common stock offered hereby will be sold in such jurisdictions only through registered or licensed brokers or dealers. In certain states, the common stock may not be sold unless they are registered or qualified for sale in such state, or unless an exemption from registration or qualification is available and is obtained.

 

I-10

 

 

We will bear all costs, expenses and fees in connection with the registration of the common stock offered hereby. However, the selling shareholders will bear any brokerage or underwriting commissions and similar selling expenses, if any, attributable to the sale of the shares of common stock offered pursuant to this reoffer prospectus. We have agreed to indemnify certain of the selling security holders against certain liabilities, including liabilities under the Act, or to contribute to payments to which any of those security holders may be required to make in respect thereof.

 

There can be no assurance that the selling shareholders will sell any or all of the securities offered by them hereby.

 

Transfer Agent and Registrar

 

The Transfer Agent and Registrar for shares of our common stock and preferred stock is VStock Transfer, LLC, Woodmere, New York. Our Transfer Agent and Registrar’s telephone number is (212) 828-8436.

DISCLOSURE OF COMMISSION POSITION ON

INDEMNIFICATION FOR SECURITIES LAW VIOLATIONS

 

We are a Delaware corporation and, accordingly, we are subject to the corporate laws under the Delaware General Corporation Law (“DGCL”). Article 8 of our Amended and Restated Articles of Incorporation, Article 7 of our amended and restated by-laws and the DGCL Statutes, contain indemnification provisions.

 

I-11

 

 

Our Amended and Restated Articles of Incorporation provides that we will indemnify, to the fullest extent permitted by applicable law, any of our directors or officers who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”) by reason of the fact that he or she is or was our director, officer, employee or agent or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any such Proceeding. We shall be required to indemnify a person in connection with a Proceeding initiated by such person only if the Proceeding was authorized by the Board of Directors. We have the power to indemnify, to the extent permitted by the DGCL, as it presently exists or may hereafter be amended from time to time, any employee or agent of ours who was or is a party or is threatened to be made a party to any Proceeding by reason of the fact that he or she is or was a director, officer, employee or agent of ours or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any such Proceeding.

 

We have entered into indemnification agreements with each of our directors and officers. These indemnification agreements require us, among other things, to indemnify our directors and officers for some expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director or officer in any action or proceeding arising out of his or her service as one of our directors or officers, or any of our subsidiaries or any other company or enterprise to which the person provides services at our request.

 

We maintain a general liability insurance policy that covers certain liabilities of directors and officers of our corporation arising out of claims based on acts or omissions in their capacities as directors or officers.

 

In any underwriting agreement we enter into in connection with the sale of common stock being registered hereby, the underwriters will agree to indemnify, under certain conditions, us, our directors, our officers and persons who control us within the meaning of the Securities Act of 1933, as amended, or the Securities Act, against certain liabilities.

 

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, 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.

Item 6. Indemnification of Directors and Officers.

 

The Registrant is a Delaware corporation and, accordingly, is subject to the corporate laws under the Delaware General Corporation Law (“DGCL”). Article 8 of the Registrant’s Amended and Restated Articles of Incorporation, Article 7 of the Registrant’s by-laws and the DGCL Statutes each contain indemnification provisions.

 

The Registrant’s Amended and Restated Articles of Incorporation provides that we will indemnify, to the fullest extent permitted by applicable law, any director or officer of the Registrant who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”) by reason of the fact that he or she is or was the Registrant’s director, officer, employee or agent or is or was serving at the Registrant’s request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any such Proceeding.

The Registrant has the power to indemnify, to the extent permitted by the DGCL, as it presently exists or may hereafter be amended from time to time, any employee or agent of the Registrant who was or is a party or is threatened to be made a party to any Proceeding by reason of the fact that he or she is or was a director, officer, employee or agent of the Registrant or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any such Proceeding.

 

The Registrant has entered into indemnification agreements with each of its directors and officers.

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

 

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the Registrant’s directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Item 9. Undertakings.

 

(a) The undersigned registrant hereby undertakes:

 

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

 

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

 

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price, set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

 

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

 

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

 

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

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

 

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

 

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

 

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of 314 securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

 

(5) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

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