THE COMPANY

The following summary highlights information found in this prospectus and the documents incorporated by reference in this prospectus. It does not contain all of the information you should consider before investing in our common stock. You should read the entire prospectus carefully, including the sections entitled “RISK FACTORS” and “INFORMATION INCORPORATED BY REFERENCE.”

Our Company

Gold Resource Corporation was organized under the laws of Colorado, USA on August 24, 1998. Since 2010, GRC has produced gold and silver doré and copper, lead, and zinc concentrates in Oaxaca, Mexico at our subsidiary, Don David Gold Mexico S.A. de C.V. (“Don David Gold Mine” or “DDGM”). The Don David Gold Mine holds six (6) properties which are all located in what is known as the San Jose structural corridor. Our properties span 55 continuous kilometers of this structural corridor which include three historic mining districts in Oaxaca.

On December 10, 2021, the Company successfully completed the acquisition of all the issued and outstanding common shares of Aquila Resources Inc (the “Aquila Transaction”). Aquila’s principal asset is its 100% interest in the Back Forty Project located in Menominee County, Michigan, USA. The Back Forty Project has a polymetallic (gold, silver, copper, lead, and zinc) Volcanogenic Massive Sulfide deposit. The Back Forty Project controls surface and mineral rights through ownership and leases with the State of Michigan. The company is currently advancing work on an optimized feasibility study. Once the feasibility work is completed, the Company’s Board of Directors will evaluate the current economic climate and make a decision on how to move forward with the Back Forty Project.

Our principal executive offices are located at 7900 E. Union Ave, Suite 320, Denver, Colorado 80237, and our telephone number is (303) 320-7708. We maintain a website at www.goldresourcecorp.com and through a link on our website you can view the periodic filings that we make with the SEC, as well as certain of our corporate governance documents such as our code of ethics. Unless specifically incorporated herein by reference, the information on our website is not part of this prospectus or the accompanying prospectus supplement.

Don David Gold Mine

The primary production stage properties at DDGM commenced operations in 2010. The current operations include the Arista underground mine and the DDGM processing facility. The DDGM processing facility currently produces doré and metal concentrates from ore mined at the Arista Mine. The Arista Mine was expanded in 2016 with the development of the Switchback vein system. The Arista Mine portal is located approximately two kilometers from the processing facility. Additionally, underground mining at the Alta Gracia mine was conducted from 2017 to 2019. Alta Gracia is approximately 32 kilometers from the processing facilities. The Arista and Alta Gracia mines include a total of approximately 30,000 hectares of mining concessions, access roads from a major highway, haul roads, a processing facility and adjoining buildings, an assay lab, a now depleted open pit, underground mines, tailings facilities, and other infrastructure.

Within the 55-kilometer-long San Jose structural corridor, in Oaxaca, Mexico, sits a highly prospective ground package. Multiple volcanic domes of various scales, and likely non-vented intrusive domes, dominate the district geology. These volcanogenic features are imposed on a pre-volcanic basement of sedimentary rocks. Gold and silver, as well as base metal mineralization in this district is related to the manifestations of this classic volcanogenic system and is considered epithermal in character. The Company intends to advance organic growth and to unlock the value of the mine, existing infrastructure, and our large property position by continuing to invest in exploration and development.

Back Forty Project

There is a long history of exploration, and studies being performed at the Back Forty Project. In 2014, a Preliminary Feasibility Study prepared under Canadian National Instrument 43-101 (“NI 43-101”) was completed which contemplated an open pit mine and processing operation. In October 2019, Aquila filed a NI 43-101 Feasibility Study. Over the next couple of years, the necessary permits were obtained. In August 2020, a Preliminary Economic Assessment was published. In January 2021, the water permit was revoked due to a technicality related to a contingent condition established in the permit. In 2021, an optimized feasibility study was initiated to address the mine’s footprint, potential for an underground mine, wetland mitigation, and other key construction and design decisions. The feasibility study is ongoing. Once the feasibility work is completed, the Company’s Board of Directors will evaluate the current economic climate and make a decision on how to move forward with the Back Forty Project.

Anti-Takeover Provisions

Provisions of Colorado law, our Articles of Incorporation and Bylaws could make it more difficult to acquire our company by means of a tender offer, a proxy contest or otherwise, or to remove incumbent officers and directors. These provisions are expected to discourage certain types of coercive takeover practices and takeover bids that our Board of Directors may consider inadequate and to encourage persons seeking to acquire control of our company to first negotiate with our Board of Directors. We believe that the benefits of increased protection of our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging takeover or acquisition proposals because, among other things, negotiation of these proposals could result in an improvement of their terms. These provisions could adversely affect the price of our common stock. Among other things, our Articles of Incorporation and Bylaws:

In addition, as a matter of Colorado law, certain significant transactions require the affirmative vote of a majority of the shares eligible to vote at a meeting of shareholders, which requirement could result in delays to, or greater cost associated with, a change in control of our company.

The applicable prospectus supplement will describe the terms of the subscription receipts to be issued, including the following:

Table of Contents

Table of Contents

FORMS OF SECURITIES

General

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

Registered Global (Book-Entry) Securities

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

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

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

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

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

Table of Contents

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

If the depositary for any of the securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, or Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

Agents designated by us may solicit offers to purchase the securities from time to time. The prospectus supplement will name any such agent involved in the offer or sale of the securities and will set forth any commissions payable by us to such agent. Unless otherwise indicated in such prospectus supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter of the securities so offered and sold.

If we utilize an underwriter in the sale of the securities offered by this prospectus, we will execute an underwriting agreement with the underwriter or underwriters at the time of sale. We will provide the name of any underwriter in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with a sale of securities offered by means of this prospectus, underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of securities for whom they may act as agent. Underwriters may sell securities offered by means of this prospectus to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agent. Any underwriting compensation paid by us to underwriters or agents in connection with the offering of securities offered by means of this prospectus, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in the applicable prospectus supplement. Underwriters, dealers, and agents participating in the distribution of the offered securities may be deemed to be underwriters, and any discounts or commissions received by them and any profit realized by them upon the resale of the offered securities may be deemed to be underwriting discounts and commissions, under the Securities Act.

Underwriters, dealers and agents may be entitled, under agreements that may be entered into with us, to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to any contribution with respect to payments which they may be required to make in respect thereof and may engage in transactions with, or perform services for, us in the ordinary course of business.

If we use delayed delivery contracts, we will, directly or through agents, underwriters or dealers, disclose that we are using them in the prospectus supplement and state when the underwriter, dealer or agent will demand payment and delivery of the securities under the delayed delivery contracts. We may further agree to adjustments before a public offering to the underwriters’ purchase price for the securities based on changes in the market value of the securities. The prospectus supplement relating to any such public offering will contain information on the number of securities to be sold, the manner of sale or other distribution, and other material facts relating to the public offering. These delayed delivery contracts will be subject only to the conditions that we set forth in the prospectus supplement.

Other than the common stock, all securities offered by this prospectus will be a new issue of securities with no established trading market. Any underwriter to whom securities are sold by us for public offering and sale may make a market in such securities, but such underwriters may not be obligated to do so and may discontinue any market making at any time without notice. The securities may or may not be listed on a national securities exchange or a foreign securities exchange, except for the common stock which is currently listed and traded on the NYSE American. Any common stock sold by this prospectus will be listed for trading on the NYSE American or other exchange on which our common stock may trade, in each case subject to official notice of issuance. We cannot give you any assurance as to the liquidity of the trading markets for any securities.

Agents, underwriters and dealers may be customers of, engage in transactions with, or perform services for, us and our subsidiaries in the ordinary course of business.

Table of Contents

Direct Sales

We may directly solicit offers to purchase our securities and may sell such securities directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale thereof. We will describe the terms of direct sales in the prospectus supplement.

Stabilization Activities

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 we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by exercising their over-allotment option, if any, or making purchases in the open market. 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.

Shares of Common Stock

​

We have entered into an At-The-Market Offering Agreement, or the Offering Agreement, with H.C. Wainwright & Co., LLC, or Wainwright, as agent. In accordance with the terms of the Offering Agreement, this prospectus supplement, and the accompanying prospectus, we may from time to time offer and sell shares of our common stock having an aggregate offering price of up to $75,000,000 through the agent.

Our shares of common stock trade on the NYSE American under the symbol “GORO.” On May 10, 2023, the last sale price of the shares as reported on the NYSE American was $0.89 per share. We intend to apply to the NYSE American for the listing of the shares of our common stock being offered by this prospectus. Listing will be subject to us fulfilling all the listing requirements of the NYSE American and is a condition of sales under the Offering Agreement.

Sales of common stock, if any, under this prospectus supplement and the accompanying prospectus may be made in transactions that are deemed to be “at-the-market” offerings as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended, or the Securities Act. Wainwright will make all sales using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between Wainwright and us. Sales of the shares of our common stock, if any, through Wainwright or directly to Wainwright acting as principal will be made by means of ordinary brokers’ transactions on the NYSE American, the existing trading market for our common stock, or any other existing trading market in the United States for our common stock, sales made to or through a market maker other than on an exchange or otherwise, directly to the sales agent as principal, in negotiated transactions with our prior approval at market prices prevailing at the time of sale or at prices related to prevailing market prices, or any other method permitted by law. If we and Wainwright agree on any method of distribution other than sales of shares of our common stock into the NYSE American or another existing trading market in the United States at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

Wainwright will receive from us a commission of up to 3% of the gross sales price of all shares sold through it under the offering agreement. In connection with the sale of the common stock on our behalf, Wainwright will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Wainwright will be deemed to be underwriting commissions or discounts.

Investing in our common stock involves risks including those described in the “Risk Factors” section beginning on page S-6 of this prospectus supplement and page 2 the accompanying prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement and the accompanying prospectus to which it relates are truthful or complete. Any representation to the contrary is a criminal offense.

H.C. Wainwright & Co.

The date of this prospectus supplement is May 12, 2023.

This summary highlights information incorporated by reference into or contained elsewhere in this prospectus supplement and the accompanying prospectus. This summary may not contain all of the information that may be important to you. You should read carefully all of the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus, including the information set forth under the caption “Risk Factors” beginning on page S-6 of this prospectus supplement and in our 2022 Form 10-K, and our consolidated financial statements and the related notes thereto incorporated by reference herein before making a decision to invest in our shares.

Overview of Our Business

Gold Resource Corporation was organized under the laws of Colorado, USA on August 24, 1998. Since 2010, GRC has produced gold and silver doré and copper, lead, and zinc concentrates in Oaxaca, Mexico at our subsidiary, Don David Gold Mexico S.A. de C.V. (“Don David Gold Mine” or “DDGM”). The Don David Gold Mine holds six (6) properties which are all located in what is known as the San Jose structural corridor. Our properties span 55 continuous kilometers of this structural corridor which include three historic mining districts in Oaxaca. We produce concentrates that contain gold, silver, copper, lead and zinc, and doré containing gold and silver at our Arista and Mirador mines in the Don David Gold Mine. We also perform exploration and evaluation work on our portfolio of precious and base metal exploration properties at both mining units and continue to evaluate other properties for possible acquisition.

On December 10, 2021, the Company successfully completed the acquisition of all the issued and outstanding common shares of Aquila Resources Inc. Aquila’s principal asset is its 100% interest in the Back Forty Project located in Menominee County, Michigan, USA. The Back Forty Project has a polymetallic (gold, silver, copper, lead, and zinc) Volcanogenic Massive Sulfide deposit. The Back Forty Project controls surface and mineral rights through ownership and leases with the State of Michigan. The company is currently advancing work on an optimized feasibility study. Once the feasibility work is completed, the Company’s Board of Directors will evaluate the current economic climate and make a decision on how to move forward with the Back Forty Project.

Our principal executive offices are located at 7900 E. Union Ave, Suite 320, Denver, Colorado 80237, and our telephone number is (303) 320-7708. We maintain a website at www.goldresourcecorp.com and through a link on our website you can view the periodic filings that we make with the SEC, as well as certain of our corporate governance documents such as our code of ethics. Unless specifically incorporated herein by reference, the information on our website is not part of this prospectus.

Don David Gold Mine

The primary production stage properties at DDGM commenced operations in 2010. The current operations include the Arista underground mine and the DDGM processing facility. The DDGM processing facility currently produces doré and metal concentrates from ore mined at the Arista Mine. The Arista Mine was expanded in 2016 with the development of the Switchback vein system. The Arista Mine portal is located approximately two kilometers from the processing facility. Additionally, underground mining at the Alta Gracia mine was conducted from 2017 to 2019. Alta Gracia is approximately 32 kilometers from the processing facilities. The Arista and Alta Gracia mines include a total of approximately 30,000 hectares of mining concessions, access roads from a major highway, haul roads, a processing facility and adjoining buildings, an assay lab, a now depleted open pit, underground mines, tailings facilities, and other infrastructure.

Within the 55-kilometer-long San Jose structural corridor, in Oaxaca, Mexico, sits a highly prospective ground package. Multiple volcanic domes of various scales, and likely non-vented intrusive domes, dominate the district geology. These volcanogenic features are imposed on a pre-volcanic basement of sedimentary rocks. Gold and silver, as well as base metal mineralization in this district is related to the manifestations of this classic volcanogenic system and is considered epithermal in character. The Company intends to advance organic growth and to unlock the value of the mine, existing infrastructure, and our large property position by continuing to invest in exploration and development.

Back Forty Project

There is a long history of exploration, and studies being performed at the Back Forty Project. In 2014, a Preliminary Feasibility Study prepared under Canadian National Instrument 43-101 (“NI 43-101”) was completed which contemplated an open pit mine and processing operation. In October 2019, Aquila filed a NI 43-101 Feasibility Study. Over the next couple of years, the necessary permits were obtained. In August 2020, a Preliminary Economic Assessment was published. In January 2021, the water permit was revoked due to a technicality related to a contingent condition established in the permit. In 2021, an optimized feasibility study was initiated to

address the mine’s footprint, potential for an underground mine, wetland mitigation, and other key construction and design decisions. The feasibility study is ongoing. Once the feasibility work is completed, the Company’s Board of Directors will evaluate the current economic climate and make a decision on how to move forward with the Back Forty Project.

The information above regarding the number of shares of our common stock outstanding is based on 88,468,542 shares of common stock outstanding as of March 31, 2023. The number of shares of our common stock outstanding as of that date does not include 7,478,710 shares reserved for issuance under our equity compensation plans, 1,475,316 shares of which are issuable upon the exercise of outstanding options to purchase common stock and 936,660 shares which are issuable upon exercise of restricted stock units. Our outstanding options have a weighted average exercise price of $2.90 per share as of March 31, 2023.

short-term, investment-grade, interest-bearing instruments and U.S. government securities. These investments may not yield a favorable return to our stockholders.

The common stock offered hereby will be sold in “at-the-market” offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

The actual number of shares we will issue under the Offering Agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the Offering Agreement and compliance with applicable law, we have the discretion to deliver a sales notice to Wainwright at any time throughout the term of the Offering Agreement. The number of shares that are sold by Wainwright after delivering a sales notice will fluctuate based on the market price of our common stock during the sales period and limits we set with Wainwright. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.

PLAN OF DISTRIBUTION

We have entered into an At-The-Market Offering Agreement with Wainwright, under which we may issue and sell our common stock having an aggregate gross sales price of up to $75,000,000 from time to time through Wainwright acting as agent. The Offering Agreement provides that sales of our common stock, if any, under this prospectus supplement may be made in sales deemed to be “at-the-market” equity offerings as defined in Rule 415(a)(4) promulgated under the Securities Act. If we and Wainwright agree on any method of distribution other than sales of shares of our common stock into the NYSE American or another existing trading market in the United States at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act. No sales will be made in Canada or into any trading market in Canada.

Wainwright will offer the common stock subject to the terms and conditions of the Offering Agreement on a daily basis or as otherwise agreed upon by us and Wainwright on any day that: (i) is a trading day for the NYSE American; (ii) we have instructed Wainwright by telephone to make such sales; and (iii) we have satisfied the conditions under Section 6 of the Offering Agreement. We will designate the maximum number of common stock to be sold through Wainwright on a daily basis. Subject to the terms and conditions of the Offering Agreement, Wainwright will use its commercially reasonable efforts to sell on our behalf all of the common stock so designated or determined. We or Wainwright may suspend the offering of common stock being made through Wainwright under the Offering Agreement upon proper notice to the other party.

We will pay Wainwright commissions, in cash, for its services in acting as agent in the sale of our common stock. Wainwright will be entitled to a placement fee of up to 3% of the gross sales price of the shares sold. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse Wainwright for certain specified expenses, including the fees and disbursements of its legal counsel in an amount not to exceed $30,000, as provided in the Offering Agreement. Additionally, pursuant to the terms of the Offering Agreement, we agreed to reimburse Wainwright for the fees and disbursements of its legal counsel in connection with Wainwright’s ongoing diligence, drafting and other filing requirements arising from the transactions contemplated by the Offering Agreement in an amount not to exceed $2,500 in the aggregate per calendar quarter. We estimate that the total expenses for the offering, excluding compensation and reimbursements payable to Wainwright under the terms of the Offering Agreement, will be approximately $50,000.

Settlement for sales of common stock will occur at 10:00 a.m. (New York City time) on the second trading day following sale of the shares (or such shorter settlement cycle as may be in effect under Exchange Act Rule 15c6-1 from time to time), or at some other time that is agreed upon by us and Wainwright in connection with a particular transaction, in return for payment of the net proceeds to us. Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Wainwright may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

Wainwright has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell on our behalf all of the common stock requested to be sold by us, subject to the conditions set forth in the Offering Agreement. In connection with the sale of the common stock on our behalf, Wainwright will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Wainwright will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to Wainwright against certain civil liabilities, including liabilities under the Securities Act.

The offering of our common stock pursuant to the Offering Agreement will terminate upon the earlier of (i) the issuance and sale of all of the common stock subject to the Offering Agreement, (ii) the three year anniversary of the effective date of the registration statement of which this prospectus supplement forms a part, and (iii) the termination of the Offering Agreement as permitted therein. We may terminate the Offering Agreement at any time upon five business days’ prior notice.

Wainwright and its affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees, although we have no current agreements to do so. To the extent required by Regulation M, Wainwright will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus.

We intend to apply to list any shares of common stock sold in this offering on the NYSE American, and approval for such listing is a condition for sales under the Offering Agreement.

This prospectus in electronic format may be made available on a website maintained by Wainwright and Wainwright may distribute this prospectus electronically.

Table of Contents

Table of Contents

Liability under federal securities law is not limited by our Articles of Incorporation.

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

Table of Contents

Provided, however, that subsections (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those subsections is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 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.
