COMPANY OVERVIEW

GeoVax Labs, Inc. (“GeoVax” or the “Company”) is a clinical-stage biotechnology company developing human vaccines against infectious diseases using our novel vaccine platform. Our platform supports production of non-infectious virus-like particles (VLPs) from the cells of the person receiving the vaccine. Producing non-infectious VLPs in the person being vaccinated circumvents the need to purify virus-like particles for inoculation. The production of VLPs in the person being vaccinated mimics a natural infection, stimulating both the humoral and cellular arms of the immune system to recognize, prevent and control the target infection should it appear.

Our current development programs are focused on vaccines against Human Immunodeficiency Virus (HIV) and hemorrhagic fever viruses (Ebola, Marburg). We believe our technology and vaccine development expertise is well-suited for a variety of human infectious diseases and, potentially, cancer immunotherapy. We intend to pursue expansion of our product pipeline.

Our most advanced HIV vaccine program is focused on the clade B subtype of HIV prevalent in the Americas and Western Europe. Our preventive clade B HIV vaccine has successfully completed Phase 2a human clinical testing and is targeted to enter a follow-on clinical trial in early 2016. It has shown outstanding safety and excellent and highly reproducible immunogenicity (Journal of Infectious Diseases volume 203, pg 610 and volume 210 pg 99). We are also extending our HIV vaccine effort to the most common virus subtype affecting sub-Saharan Africa, clade C and are conducting preclinical studies pursuant to a grant from the National Institutes of Health (NIH). Additionally, we are investigating our HIV vaccines for their potential to contribute to combination therapies for therapeutic treatment leading to a cure for HIV infections.

Our hemorrhagic fever vaccine program was initiated during 2014 with the objective of developing both monovalent vaccines and tetravalent vaccines designed to protect not only against current strains for filoviruses such as Ebola and Marburg, but also against other major hemorrhagic fever viruses endemic in African countries. Studies of our first Ebola vaccine candidate have demonstrated 100 percent protection in rodent models. We plan to conduct additional animal challenge studies during 2016 with the goal of beginning human clinical trials during the first half of 2017.

In December 2015, we entered into a Collaborative Research Agreement with the University of Pittsburgh to evaluate our VLP vaccine platform for use in cancer immunotherapy, including the selection and testing of vaccine candidates.

Our vaccine development activities have been, and continue to be, financially supported by the U.S. government. This support has been both in the form of research grants awarded directly to us, as well as indirect support for the conduct of our human clinical trials. This is discussed further under “Support from the United States Government” below.

Our HIV vaccine technology was developed in collaboration with researchers at Emory University, the NIH, and the Centers for Disease Control and Prevention (CDC). The technology developed by the collaboration is exclusively licensed to us from Emory University. We also have nonexclusive licenses to certain patents owned by the NIH. Our hemorrhagic fever virus vaccines have been developed with technology licensed from, and in collaboration with, the NIH.

Each of our vaccine development programs is discussed in greater detail in the sections that follow below.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review and consider the risks, uncertainties and other factors described below before you decide whether to purchase our securities. Any of these factors could materially and adversely affect our business, financial condition, operating results and prospects and could negatively impact the market price of our common stock, and you may lose some or all of your investment. The risks and uncertainties described below are not the only ones facing our Company. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, may also impair our business operations. You should also refer to the information contained in this prospectus, including our financial statements and the related notes.

Risks Related to Our Business

We have a history of operating losses, and we expect losses to continue for the foreseeable future.

We have had no product revenue to date and there can be no assurance that we will ever generate any product revenue. We have experienced operating losses since we began operations in 2001. As of September 30, 2015, we had an accumulated deficit of approximately $31.8 million. We expect to incur additional operating losses and expect cumulative losses to increase as our research and development, pre-clinical, clinical, manufacturing and marketing efforts expand. Our ability to generate revenue and achieve profitability depends on our ability to successfully complete the development of our product candidates, conduct pre-clinical tests and clinical trials, obtain the necessary regulatory approvals, and manufacture and market the resulting products. Unless we are able to successfully meet these challenges, we will not be profitable and may not remain in business.

Our business will require continued funding. If we do not receive adequate funding, we will not be able to continue our operations.

To date, we have financed our operations principally through the private placement of our equity securities and through NIH grants. We will require substantial additional financing at various intervals for our operations, including clinical trials, operating expenses, intellectual property protection and enforcement, for pursuit of regulatory approvals, and for establishing or contracting out manufacturing, marketing and sales functions. There is no assurance that such additional funding will be available on terms acceptable to us or at all. If we are not able to secure the significant funding that is required to maintain and continue our operations at current levels, or at levels that may be required in the future, we may be required to delay clinical studies or clinical trials, curtail operations, or obtain funds through collaborative arrangements that may require us to relinquish rights to some of our products or potential markets.

The costs of conducting all of our human clinical trials to date for our preventive HIV vaccine have been borne by the HIV Vaccine Trials Network (HVTN), with funding by the NIH, and we expect NIH support for additional clinical trials. GeoVax incurs costs associated with manufacturing the clinical vaccine supplies and other study support. We cannot predict the level of support we will receive from the HVTN or the NIH for any additional clinical trials of our HIV vaccines.

Our operations are also partially supported by the NIH grants awarded to us to support our HIV/AIDS vaccine program. As of September 30, 2015, there was approximately $261,000 of unused grant funds remaining and available for use during the remainder of 2015 and the first half of 2016. We are pursuing additional grants from the federal government for both our HIV and Ebola/Marburg vaccine programs. However, as we progress to the later stages of our vaccine development activities, government financial support may be more difficult to obtain, or may not be available at all. Furthermore, there is some risk that actual funding for grants could be delayed, cut back, or eliminated due to government budget constraints. Therefore, it will be necessary for us to look to other sources of funding in order to finance our development activities.

We expect that our current working capital, combined with proceeds from the grants awarded to us from the NIH will be sufficient to support our planned level of operations through the first quarter of 2016. We will need to raise additional funds to significantly advance our vaccine development programs and to continue our operations beyond the first quarter of 2016. In order to meet our operating cash flow requirements we plan to seek sources of non-dilutive capital through government grant programs and clinical trial support. We may also plan additional offerings of our equity securities, debt, or convertible debt instruments. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could have a material adverse effect on our business, operating results, financial condition and prospects.

Risks Related to Development and Commercialization of Product Candidates and Dependence on Third Parties

Our products are still being developed and are unproven. These products may not be successful

To become profitable, we must generate revenue through sales of our products. However, our products are in varying stages of development and testing. Our products have not been proven in human clinical trials and have not been approved by any government agency for sale. If we cannot successfully develop and prove our products and processes, or if we do not develop other sources of revenue, we will not become profitable and at some point we would discontinue operations.

Whether we are successful will be dependent, in part, upon the leadership provided by our management. If we were to lose the services of any of these individuals, our business and operations may be adversely affected. Further, we may not carry key man life insurance on certain of our executive officers or directors.

Whether our business will be successful will be dependent, in part, upon the leadership provided by our officers, particularly our President and Chief Executive Officer and our Chief Scientific Officer. The loss of the services of these individuals may have an adverse effect on our operations. Although we carry some key man life insurance on Dr. Harriet L. Robinson, the amount of such coverage may not be sufficient to offset any adverse economic effects on our operations and we do not carry key man insurance on any of our other executive officers or directors. Further, our employees, including our executive officers and directors, are not subject to any covenants not to compete against the Company, and our business could be adversely affected if any of our employees or directors engaged in an enterprise competitive with the Company.

Regulatory and legal uncertainties could result in significant costs or otherwise harm our business.

To manufacture and sell our products, we must comply with extensive domestic and international regulation. In order to sell our products in the United States, approval from the FDA is required. Satisfaction of regulatory requirements, including FDA requirements, typically takes many years, and if approval is obtained at all, it is dependent upon the type, complexity and novelty of the product, and requires the expenditure of substantial resources. We cannot predict whether our products will be approved by the FDA. Even if they are approved, we cannot predict the time frame for approval. Foreign regulatory requirements differ from jurisdiction to jurisdiction and may, in some cases, be more stringent or difficult to meet than FDA requirements. As with the FDA, we cannot predict if or when we may obtain these regulatory approvals. If we cannot demonstrate that our products can be used safely and successfully in a broad segment of the patient population on a long-term basis, our products would likely be denied approval by the FDA and the regulatory agencies of foreign governments.

We face intense competition and rapid technological change that could result in products that are superior to the products we will be commercializing or developing.

The market for vaccines that protect against or treat human infectious diseases is intensely competitive and is subject to rapid and significant technological change. We have numerous competitors in the United States and abroad, including, among others, large companies with substantially greater resources than us. These competitors may develop technologies and products that are more effective or less costly than any of our future technology or products or that could render our technology or products obsolete or noncompetitive. If our technology or products are not competitive, we may not be able to remain in business.

Our product candidates are based on new medical technology and, consequently, are inherently risky. Concerns about the safety and efficacy of our products could limit our future success.

We are subject to the risks of failure inherent in the development of product candidates based on new medical technologies. These risks include the possibility that the products we create will not be effective, that our product candidates will be unsafe or otherwise fail to receive the necessary regulatory approvals, and that our product candidates will be hard to manufacture on a large scale or will be uneconomical to market.

Many pharmaceutical products cause multiple potential complications and side effects, not all of which can be predicted with accuracy and many of which may vary from patient to patient. Long term follow-up data may reveal additional complications associated with our products. The responses of potential physicians and others to information about complications could materially affect the market acceptance of our products, which in turn would materially harm our business.

4

We may experience delays in our clinical trials that could adversely affect our financial results and our commercial prospects.

We do not know whether planned clinical trials will begin on time or whether we will complete any of our clinical trials on schedule, if at all. Product development costs will increase if we have delays in testing or approvals or if we need to perform more or larger clinical trials than planned. Significant delays may adversely affect our financial results and the commercial prospects for our products, and delay our ability to become profitable.

We rely heavily on the HVTN, independent clinical investigators, and other third party service providers for successful execution of our clinical trials, but do not control many aspects of their activities. We are responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as Good Clinical Practices, for conducting, recording, and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Third parties may not complete activities on schedule, or may not conduct our clinical trials in accordance with regulatory requirements or our stated protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our product candidates. There is also a risk of changes in clinical trial strategy and timelines due to the HVTN and the NIH altering their trial strategy.

Failure to obtain timely regulatory approvals required to exploit the commercial potential of our products could increase our future development costs or impair our future sales.

None of our vaccines are approved by the FDA for sale in the United States or by other regulatory authorities for sale in foreign countries. To exploit the commercial potential of our technologies, we are conducting and planning to conduct additional pre-clinical studies and clinical trials. This process is expensive and can require a significant amount of time. Failure can occur at any stage of testing, even if the results are favorable. Failure to adequately demonstrate safety and efficacy in clinical trials could delay or preclude regulatory approval and restrict our ability to commercialize our technology or products. Any such failure may severely harm our business. In addition, any approvals we obtain may not cover all of the clinical indications for which approval is sought, or may contain significant limitations in the form of narrow indications, warnings, precautions or contraindications with respect to conditions of use, or in the form of onerous risk management plans, restrictions on distribution, or post-approval study requirements.

State pharmaceutical marketing compliance and reporting requirements may expose us to regulatory and legal action by state governments or other government authorities.

In recent years, several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs and file periodic reports on sales, marketing, pricing and other activities. Similar legislation is being considered in other states. Many of these requirements are new and uncertain, and available guidance is limited. Unless we are in full compliance with these laws, we could face enforcement action, fines, and other penalties and could receive adverse publicity, all of which could harm our business.

We may be subject to new federal and state legislation to submit information on our open and completed clinical trials to public registries and databases.

In 1997, a public registry of open clinical trials involving drugs intended to treat serious or life-threatening diseases or conditions was established under the FDA Modernization Act (FDMA), to promote public awareness of and access to these clinical trials. Under the FDMA, pharmaceutical manufacturers and other trial sponsors are required to post the general purpose of these trials, as well as the eligibility criteria, location and contact information of the trials. Since the establishment of this registry, there has been significant public debate focused on broadening the types of trials included in this or other registries, as well as providing for public access to clinical trial results. A voluntary coalition of medical journal editors has adopted a resolution to publish results only from those trials that have been registered with a no-cost, publicly accessible database, such as www.clinicaltrials.gov. Federal legislation was introduced in the fall of 2004 to expand www.clinicaltrials.gov and to require the inclusion of trial results in this registry. The Pharmaceutical Research and Manufacturers of America also issued voluntary principles for its members to make results from certain clinical trials publicly available and established a website for this purpose. Other groups have adopted or are considering similar proposals for clinical trial registration and the posting of clinical trial results. Failure to comply with any clinical trial posting requirements could expose us to negative publicity, fines and other penalties, all of which could materially harm our business.

5

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our drug candidates and affect the prices we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of our drug candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any drug candidates for which we obtain marketing approval.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively the PPACA, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the PPACA of importance to our potential drug candidates are:

● | an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents, apportioned among these entities according to their market share in certain government healthcare programs;

● | an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average manufacturer price for branded and generic drugs, respectively;

● | expansion of healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute, new government investigative powers and enhanced penalties for non-compliance;

● | a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for a manufacturer’s outpatient drugs to be covered under Medicare Part D;

● | extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

● | expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for certain individuals with income at or below 133% of the federal poverty level beginning in 2014, thereby potentially increasing a manufacturer’s Medicaid rebate liability;

● | expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;

● | the new requirements under the federal Open Payments program and its implementing regulations;

● | a new requirement to annually report drug samples that manufacturers and distributors provide to physicians; and

● | a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, starting in 2013. On March 1, 2013, the President signed an executive order implementing the 2% Medicare payment reductions, and on April 1, 2013, these reductions went into effect. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our drugs, if approved, and, accordingly, our financial operations.

We expect that the PPACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payers. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our drugs.

6

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our drug candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

We may not be successful in establishing collaborations for product candidates we may seek to commercialize, which could adversely affect our ability to discover, develop, and commercialize products.

We expect to seek collaborations for the development and commercialization of product candidates in the future. The timing and terms of any collaboration will depend on the evaluation by prospective collaborators of the clinical trial results and other aspects of our vaccine’s safety and efficacy profile. If we are unable to reach agreements with suitable collaborators for any product candidate, we will be forced to fund the entire development and commercialization of such product candidates, ourselves, and we may not have the resources to do so. If resource constraints require us to enter into a collaboration agreement early in the development of a product candidate, we may be forced to accept a more limited share of any revenues this product may eventually generate. We face significant competition in seeking appropriate collaborators. Moreover, these collaboration arrangements are complex and time-consuming to negotiate and document. We may not be successful in our efforts to establish collaborations or other alternative arrangements for any product candidate. Even if we are successful in establishing collaborations, we may not be able to ensure fulfillment by collaborators of their obligations or our expectations.

We do not have manufacturing, sales or marketing experience.

We do not have experience in manufacturing, selling, or marketing vaccines. To obtain the expertise necessary to successfully manufacture, market, and sell our vaccines, we will require the development of our own commercial infrastructure and/or collaborative commercial arrangements and partnerships. Our ability to execute our current operating plan is dependent on numerous factors, including, the performance of third party collaborators with whom we may contract.

Our vaccines under development may not gain market acceptance.

Our vaccines may not gain market acceptance among physicians, patients, healthcare payers and the medical community. Significant factors in determining whether we will be able to compete successfully include:

● | the efficacy and safety of our vaccines;

● | the time and scope of regulatory approval;

● | reimbursement coverage from insurance companies and others;

● | the price and cost-effectiveness of our products; and

● | the ability to maintain patent protection.

We may be required to defend lawsuits or pay damages for product liability claims.

Product liability is a major risk in testing and marketing biotechnology and pharmaceutical products. We may face substantial product liability exposure in human clinical trials and for products that we sell after regulatory approval. We carry product liability insurance and we expect to continue such policies. However, product liability claims, regardless of their merits, could exceed policy limits, divert management’s attention, and adversely affect our reputation and the demand for our products.

Risks Related to Our Intellectual Property

We could lose our license rights to our important intellectual property if we do not fulfill our contractual obligations to our licensors.

Our rights to significant parts of the technology we use in our vaccines are licensed from third parties and are subject to termination if we do not fulfill our contractual obligations to our licensors. Termination of intellectual property rights under any of our license agreements could adversely impact our ability to produce or protect our vaccines. Our obligations under our license agreements include requirements that we make milestone payments to our licensors upon the achievement of clinical development and regulatory approval milestones, royalties as we sell commercial products, and reimbursement of patent filing and maintenance expenses. Should we become bankrupt or otherwise unable to fulfill our contractual obligations, our licensors could terminate our rights to critical technology that we rely upon.

7

Other parties may claim that we infringe their intellectual property or proprietary rights, which could cause us to incur significant expenses or prevent us from selling products.

Our success will depend in part on our ability to operate without infringing the patents and proprietary rights of third parties. The manufacture, use and sale of new products have been subject to substantial patent rights litigation in the pharmaceutical industry. These lawsuits generally relate to the validity and infringement of patents or proprietary rights of third parties. Infringement litigation is prevalent with respect to generic versions of products for which the patent covering the brand name product is expiring, particularly since many companies that market generic products focus their development efforts on products with expiring patents. Pharmaceutical companies, biotechnology companies, universities, research institutions or other third parties may have filed patent applications or may have been granted patents that cover aspects of our products or our licensors’ products, product candidates or other technologies.

Future or existing patents issued to third parties may contain patent claims that conflict with our products. We expect to be subject to infringement claims from time to time in the ordinary course of business, and third parties could assert infringement claims against us in the future with respect to our current products or with respect to products that we may develop or license. Litigation or interference proceedings could force us to:

● | stop or delay selling, manufacturing or using products that incorporate, or are made using the challenged intellectual property;

● | pay damages; or

● | enter into licensing or royalty agreements that may not be available on acceptable terms, if at all.

Any litigation or interference proceedings, regardless of their outcome, would likely delay the regulatory approval process, be costly and require significant time and attention of our key management and technical personnel.

Any inability to protect intellectual property rights in the United States and foreign countries could limit our ability to manufacture or sell products.

We will rely on trade secrets, unpatented proprietary know-how, continuing technological innovation and, in some cases, patent protection to preserve our competitive position. Our patents and licensed patent rights may be challenged, invalidated, infringed or circumvented, and the rights granted in those patents may not provide proprietary protection or competitive advantages to us. We and our licensors may not be able to develop patentable products. Even if patent claims are allowed, the claims may not issue, or in the event of issuance, may not be sufficient to protect the technology owned by or licensed to us. If patents containing competitive or conflicting claims are issued to third parties, we may be prevented from commercializing the products covered by such patents, or may be required to obtain or develop alternate technology. In addition, other parties may duplicate, design around or independently develop similar or alternative technologies.

We may not be able to prevent third parties from infringing or using our intellectual property, and the parties from whom we may license intellectual property may not be able to prevent third parties from infringing or using the licensed intellectual property. We generally will attempt to control and limit access to, and the distribution of, our product documentation and other proprietary information. Despite efforts to protect this proprietary information, unauthorized parties may obtain and use information that we may regard as proprietary. Other parties may independently develop similar know-how or may even obtain access to these technologies.

The laws of some foreign countries do not protect proprietary information to the same extent as the laws of the United States, and many companies have encountered significant problems and costs in protecting their proprietary information in these foreign countries.

Neither the U.S. Patent and Trademark Office nor the courts have established a consistent policy regarding the breadth of claims allowed in pharmaceutical patents. The allowance of broader claims may increase the incidence and cost of patent interference proceedings and the risk of infringement litigation. On the other hand, the allowance of narrower claims may limit the value of our proprietary rights.

Risks Related To This Offering and Our Securities

The market price of our common stock is highly volatile.

The market price of our common stock has been, and is expected to continue to be, highly volatile. Certain factors, including announcements of new developments by us or other companies, regulatory matters, new or existing medicines or procedures, concerns about our financial position, operating results, litigation, government regulation, developments or disputes relating to agreements, patents or proprietary rights, may have a significant impact on the market price of our stock. In addition, potential dilutive effects of future sales of shares of common stock by us, and subsequent sales of common stock by the holders of warrants and options could have an adverse effect on the market price of our shares.

Our common stock does not have a vigorous trading market and investors may not be able to sell their securities when desired.

We have a limited active public market for our common shares. A more active public market, allowing investors to buy and sell large quantities of our common stock, may never develop. Consequently, investors may not be able to liquidate their investments in the event of an emergency or for any other reason.

We have never paid dividends and have no plans to do so.

Holders of shares of our common stock are entitled to receive such dividends as may be declared by our Board of Directors. To date, we have paid no cash dividends on our shares of common stock and we do not expect to pay cash dividends on our common stock in the foreseeable future. We intend to retain future earnings, if any, to provide funds for operations of our business. Therefore, any potential return investors may have in our common stock will be in the form of appreciation, if any, in the market value of their shares of common stock.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud.

We are subject to reporting obligations under the United States securities laws. The Securities and Exchange Commission (SEC) as required by the Sarbanes-Oxley Act of 2002, adopted rules requiring every public company to include a management report on such company’s internal controls over financial reporting in its annual report. Effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent fraud. As a result, our failure to achieve and maintain effective internal controls over financial reporting could result in the loss of investor confidence in the reliability of our financial statements, which in turn could negatively impact the trading price of our stock.

If we fail to remain current in our reporting requirements, our securities could be removed from the OTC Market, which would limit the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market.

United States companies trading on the OTC Market must be reporting issuers under Section 12 of the Exchange Act, and must be current in their reports under Section 13. If we fail to remain current on our reporting requirements, we could be removed from the OTC Market. As a result, the market liquidity for our securities could be severely adversely affected by limiting the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market.

We expect to need additional capital, and the sale of additional shares or other equity securities could result in additional dilution to our stockholders.

We believe that our current cash and cash equivalents, combined with anticipated cash flow from our NIH grants will be sufficient to meet our anticipated cash needs through the first quarter of 2016. In order to meet our operating cash flow requirements we plan additional offerings of our equity securities, debt, or convertible debt instruments. The sale of additional equity securities could result in additional dilution to our stockholders. Certain equity securities, such as convertible preferred stock or warrants, may contain anti-dilution provisions which could result in the issuance of additional shares at lower prices if we sell other shares below specified prices. The incurrence of indebtedness would result in debt service obligations and could result in operating and financing covenants that would restrict our operations. We cannot assure investors that financing will be available in amounts or on terms acceptable to us, if at all.

Our directors and executive officers beneficially own a significant amount of our common stock and will be able to exercise significant influence on matters requiring stockholder approval.

As of December 11, 2015, our directors and executive officers collectively beneficially own approximately 8.7% of our common stock and Emory University beneficially owns 14.5%. If our directors and executive officers move to act in concert with Emory University, they may be able to exert significant influence over the election of directors and the outcome of most corporate actions requiring stockholder approval and our business, which may have the effect of delaying or precluding a third party from acquiring control of us.

The exercise of options or warrants or conversion of our Series B or Series C Preferred Stock may depress our stock price and may result in significant dilution to our common stockholders.

There are a significant number of outstanding warrants and options to purchase our stock and we have issued Series B and Series C Convertible Preferred Stock that is convertible into our Common Stock. If the market price of our Common Stock exceeds the exercise price of outstanding warrants and options or the conversion prices of the Series B or Series C Convertible Preferred Stock, holders of those securities may be likely to exercise their warrants and options or convert their preferred shares and sell the Common Stock acquired upon exercise or conversion of such securities, as applicable, in the open market. Sales of a substantial number of shares of our Common Stock in the public market by holders of warrants, options, or preferred shares may depress the prevailing market price for our Common Stock and could impair our ability to raise capital through the future sale of our equity securities. Additionally, if the holders of outstanding options, warrants, or preferred shares exercise those options or warrants or convert those preferred shares, as applicable, our common stockholders will incur dilution in their relative percentage ownership. The prospect of this possible dilution may also impact the price of our Common Stock.

Our outstanding options and warrants include warrants to purchase up to 34,666,665 shares with an exercise price of $0.11299 per share, and warrants to purchase up to 19,357,332 shares with an exercise price of $0.09416 per share. These warrants contain anti-dilution provisions, which may, under certain circumstances, reduce the exercise price (but have no effect on the number of shares subject to the warrants) to match if we sell or grant options to purchase, including rights to reprice, our common stock or common stock equivalents at a price lower than the exercise price of the warrants, or if we announce plans to do so. This potential reduction in exercise price could reduce the funds the Company receives upon exercise of the warrants, and increase the likelihood that a dilutive issuance will occur.

Our common stock is and likely will remain subject to the SEC’s “penny stock” rules, which make it more difficult to sell.

Our common stock is currently and may remain classified as a “penny stock.” The SEC rules regarding penny stocks may have the effect of reducing trading activity in our shares, making it more difficult for investors to sell. Under these rules, broker-dealers who recommend such securities to persons other than institutional accredited investors must:

• | make a special written suitability determination for the purchaser;

• | receive the purchaser’s written agreement to a transaction prior to sale;

• | provide the purchaser with risk disclosure documents which identify certain risks associated with investing in “penny stocks” and which describe the market for these “penny stocks” as well as a purchaser’s legal remedies;

• | obtain a signed and dated acknowledgment from the purchaser demonstrating that the purchaser has received the required risk disclosure document before a transaction in a “penny stock” can be completed; and

• | give bid and offer quotations and broker and salesperson compensation information to the customer orally or in writing before or with the confirmation.

These rules make it more difficult for broker-dealers to effectuate customer transactions and trading activity in our securities and may result in a lower trading volume of our common stock and lower trading prices.

Certain provisions of our certificate of incorporation which authorize the issuance of additional shares of preferred stock may make it more difficult for a third party to effect a change in control.

Our certificate of incorporation authorizes our Board of Directors to issue up to 10,000,000 shares of preferred stock. We have issued 100 shares of Series B Convertible Preferred Stock and 3,000 shares of our Series C Convertible Preferred Stock. We believe the terms of these preferred shares would not have a substantial impact on the ability of a third party to effect a change in control. The remaining shares of preferred stock may be issued in one or more series, the terms of which may be determined at the time of issuance by our Board of Directors without further action by the stockholders. These terms may include voting rights including the right to vote as a series on particular matters, preferences as to dividends and liquidation, conversion rights, redemption rights and sinking fund provisions. The issuance of any preferred stock could diminish the rights of holders of our common stock, and therefore could reduce the value of our common stock. In addition, specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with, or sell assets to, a third party. The ability of our Board of Directors to issue preferred stock could make it more difficult, delay, discourage, prevent or make it more costly to acquire or effect a change-in-control, which in turn could prevent the stockholders from recognizing a gain in the event that a favorable offer is extended and could materially and negatively affect the market price of our common stock.

10

P rovisions contained in certain of our outstanding warrants may make it more difficult for a third party to effect a change in control.

Our outstanding warrants include warrants to purchase up to 54,023,997 shares which contain provisions permitting the holders to require the payment to them of an amount of cash equal to the value (based on a Black-Scholes computation) of the remaining unexercised portion of the warrants on the date of the consummation of a fundamental transaction (as defined, but generally a change in control of the Company) that is (i) an all cash transaction, (ii) a “going private” transaction, or (ii) a transaction involving a person or entity not traded on a national securities exchange. The prospect of making such payments may discourage a potential third party acquirer.

The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “plan” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained in this prospectus are based on our current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described in the section titled “Risk Factors.” Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. “Risk Factors” and “Business,” as well as other sections in this prospectus or incorporated by reference into this prospectus, discuss some of the factors that could contribute to these differences.

The forward-looking statements made in this prospectus relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. Other factors besides those described in this prospectus could also affect our actual results.

11

This prospectus also contains market data related to our business and industry. These market data include projections that are based on a number of assumptions. While we believe these assumptions to be reasonable and sound as of the date of this prospectus, if these assumptions turn out to be incorrect, actual results may differ from the projections based on these assumptions. As a result, our markets may not grow at the rates projected by these data, or at all. The failure of these markets to grow at these projected rates may have a material adverse effect on our business, results of operations, financial condition and the market price of our common stock.

USE OF PROCEEDS

We will not receive proceeds from the sales by the selling stockholders.

BUSINESS

Overview

GeoVax Labs, Inc. (“GeoVax” or the “Company”) is a clinical-stage biotechnology company developing human vaccines against infectious diseases using our novel vaccine platform. Our platform supports production of non-infectious virus-like particles (VLPs) from the cells of the person receiving the vaccine. Producing non-infectious virus-like particles in the person being vaccinated circumvents the need to purify virus-like particles for inoculation. The production of virus-like particles in the person being vaccinated mimics a natural infection, stimulating both the humoral and cellular arms of the immune system to recognize, prevent and control the target infection should it appear.

Our current development programs are focused on vaccines against Human Immunodeficiency Virus (HIV) and hemorrhagic fever viruses (Ebola, Marburg). We believe our technology and vaccine development expertise is well-suited for a variety of human infectious diseases and, potentially, cancer immunotherapy. We intend to pursue expansion of our product pipeline.

Our most advanced HIV vaccine program is focused on the clade B subtype of HIV prevalent in the Americas and Western Europe. Our preventive clade B HIV vaccine has successfully completed Phase 2a human clinical testing and is targeted to enter a follow-on clinical trial in early 2016. It has shown outstanding safety and excellent and highly reproducible immunogenicity (Journal of Infectious Diseases volume 203, pg 610 and volume 210 pg 99). We are also extending our HIV vaccine effort to the most common virus subtype affecting sub-Saharan Africa, clade C and are conducting preclinical studies pursuant to a grant from the National Institutes of Health (NIH). Additionally, we are investigating our HIV vaccines for their potential to contribute to combination therapies for therapeutic treatment leading to a cure for HIV infections.

Our hemorrhagic fever vaccine program was initiated during 2014 with the objective of developing both monovalent vaccines and tetravalent vaccines designed to protect not only against current strains for filoviruses such as Ebola and Marburg, but also against other major hemorrhagic fever viruses endemic in African countries. Studies of our first Ebola vaccine candidate have demonstrated 100 percent protection in rodent models. We plan to conduct additional animal challenge studies during 2016 with the goal of beginning human clinical trials during the first half of 2017.

In December 2015, we entered into a Collaborative Research Agreement with the University of Pittsburgh to evaluate our VLP vaccine platform for use in cancer immunotherapy, including the selection and testing of vaccine candidates.

Our vaccine development activities have been, and continue to be, financially supported by the U.S. government. This support has been both in the form of research grants awarded directly to us, as well as indirect support for the conduct of our human clinical trials. This is discussed further under “Support from the United States Government” below.

Our HIV vaccine technology was developed in collaboration with researchers at Emory University, the NIH, and the Centers for Disease Control and Prevention (CDC). The technology developed by the collaboration is exclusively licensed to us from Emory University. We also have nonexclusive licenses to certain patents owned by the NIH. Our Ebola/Marburg vaccines have been developed with technology licensed from, and in collaboration with, the NIH.

Each of our vaccine development programs is discussed in greater detail in the sections that follow below.

We are incorporated in Delaware, and our offices and laboratory facilities are located in Smyrna, Georgia (metropolitan Atlanta).

Our Technology

Vaccines typically contain agents (antigens) that resemble disease-causing microorganisms. Traditional vaccines are often made from weakened or killed forms of the virus or from its surface proteins. Many newer vaccines use recombinant DNA (deoxyribonucleic acid) technology to generate vaccine antigens in bacteria or cultured cells from specific portions of the DNA sequence of the target pathogen. The generated antigens are then purified and formulated for use in a vaccine. The most successful of these purified antigens have been non-infectious virus-like particles (VLPs) as exemplified by vaccines for hepatitis B (Merck’s Recombivax® and GSK’s Engerix®) and Papilloma viruses (GSK’s Cervarix®, and Merck’s Gardasil®). Our approach uses recombinant DNA or recombinant viruses to produce VLPs in the person being vaccinated. In human clinical trials of our HIV vaccines, we have demonstrated that our VLPs, expressed in the cells of the person being vaccinated, are safe, yet elicit both strong and durable humoral and cellular immune response.

All of our vaccines are designed to produce self-assembling non-infectious VLPs in the cells of the person being vaccinated. VLPs train the body’s immune system to recognize and kill the authentic virus should it appear. VLPs also train the immune system to recognize and kill infected cells to control infection and reduce the length and severity of disease. One of the biggest challenges with VLP-based vaccines is to design the vaccines in such a way that the VLPs will be recognized by the immune system in the same way as the authentic virus would be. When VLPs for enveloped viruses like HIV, Ebola, and Marburg are produced in vivo, they include not only the protein antigens, but also an envelope consisting of membranes from the vaccinated individual’s cells. In this way, they are highly similar to the virus generated in a person’s body during a natural infection. VLPs produced externally, by contrast, have no envelope; or, envelopes from the cultured cells (typically hamster or insect cells) used to produce them. We believe our technology provides distinct advantages by producing VLPs that more closely resemble the authentic virus, which in turn, allows the body’s immune system to more readily recognize the authentic virus. By producing VLPs in vivo, we avoid potential purification issues associated with in vitro production of VLPs.

DNA and MVA as Vaccine Vectors. Our HIV vaccines incorporate two delivery components (or vectors): a recombinant plasmid DNA vaccine, and a recombinant MVA (modified vaccinia Ankara) vaccine. Our Ebola and Marburg vaccines use only the MVA vector. Both our DNA and MVA vaccines express sufficient vaccine genes to support the production of non-infectious VLPs. The VLPs cannot cause disease because they contain mutated or deleted enzymatic functions that are essential for virus replication. The virus-like particles display trimeric membrane bound forms of the viral envelope glycoprotein (Env for HIV or GP for Ebola or Marburg). This is important because the natural form of the envelope glycoprotein elicits multi-target antibody capable of recognizing incoming virus and blocking infections. Expression of multiple proteins by the vaccines is essential for the formation of VLPs. The multiple proteins also provide more targets for immune responses such as cytotoxic T-cells. Elicitation of multi-target humoral and cellular responses limits immune escape, just as multi-drug therapies limit drug escape.

Ebola VLPs HIV VLPs

Figure 1. Electron micrographs showing the virus-like particles (VLPs) elicited by GeoVax vaccines from human cells. Note that the Ebola VLPs on the left self-assemble into the rod-like shape of the authentic Ebola virus, while the HIV VLPs shown on the right take on the spherical shape of the authentic HIV virus. While below the resolution of these micrographs, both types of VLPs display what we believe to be the native form of their respective viral envelope glycoproteins which we believe is key to generating an effective immune humoral response.

We selected MVA for use as the live viral component of our vaccines because of its well-established safety record and because of the ability of this vector to carry sufficient viral proteins to produce virus-like particles. MVA was originally developed as a safer smallpox vaccine for use in immune compromised humans. It was developed by attenuating the standard smallpox vaccine by making over 500 passages of the virus in chicken embryos or chick embryo fibroblasts, which resulted in a virus with limited ability to replicate in human cells but did not compromise the ability of MVA to grow on avian cells, which are used for manufacturing the virus. The deletions also resulted in the loss of immune evasion genes which assist the spread of wild type smallpox infections, even in the presence of human immune responses. MVA was safely administered to over 120,000 people in the 1970s as a smallpox vaccine.

Induction of T-cell and Antibody Immune Responses. In both preclinical and clinical trials, our HIV vaccines have been shown to induce both humoral (antibody) and cellular (T-cell) responses against HIV. The induction of both antibodies and T-cells is beneficial because these immune responses work through different mechanisms. Antibodies prevent infection by blocking viruses from infecting cells. In preclinical simian vaccine studies using repeated rectal challenges with moderate doses of virus, the avidity, or tightness, of antibody binding to the surface envelope glycoprotein of HIV correlates with the prevention of infection (The Journal of Infectious Diseases, 204:164 (2011)). In high dose challenges that infect all animals at the first exposure, the avidity of the antibody for envelope glycoprotein correlates with reduced levels of virus replication (Journal of Virology, 83:4102 (2009)). Similarly, antibody responses are believed to be critical for vaccine-elicited protection against Ebola and Marburg infection (Expert Review of Vaccines, 10:63 (2011)). These results likely reflect the tightly binding antibody both blocking infection as well as tagging virus and infected cells for destruction, by white blood cells such as macrophages, neutrophils and natural killer cells. Our vaccines elicit CD8+ T-cells, a type of T-cell that can recognize and kill cells that become infected by virus (without antibody tagging). For HIV, CD8+ T-cells are important for the control of the virus that has established an infection. For Ebola and Marburg, antibodies can stop or slow the progress of infection, but T cells are important for clearing the infection by killing remaining infected cells.

Background – Viruses and Vaccines

What are Viruses? Viruses are microscopic organisms consisting of genetic material comprised of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid), surrounded by a protein, lipid (fat), or glycoprotein coat. Viruses invade healthy, living host cells in order to replicate and spread. In many cases, the body’s immune system can recognize and effectively combat an infection caused by a virus. However, with certain viral infections, the body’s immune system is unable to fully destroy or inhibit the replication of the virus, which results in persistent and ongoing viral replication resulting in disease.

Infections caused by viruses can be chronic or acute. Chronic infections, such as those caused by HIV, do not typically self-resolve with time and can cause chronic disease. Acute infections associated with viruses, such as influenza, generally last for a relatively short period of time, and self-resolve in most immunocompetent individuals. However, certain acute infections, such as those caused by Ebola and Marburg, can overwhelm the immune system, resulting in serious disease and death.

15

Viruses can also be characterized as either active or latent. An active virus can cause a persistent infection or disease over an extended period of time. A latent virus will remain in the body for very long periods of time after the initial infection and generally will only cause disease when the body’s immune system weakens, fails or is suppressed, allowing the virus to once again replicate. Vaccines have been widely used to prevent active viral infections from occurring. Latent infections are more difficult to address with vaccines. A latent virus does not replicate actively and can “fly below the radar” of the immune system in that it does not provide the immune system with targets for antibody and T-cell responses.

Viruses that develop resistance to antiviral drugs are increasingly becoming a challenge in the treatment of viral infections, particularly those that are chronic in nature. The ability of viruses to mutate spontaneously during replication allows drug-resistant strains to emerge when patients are using drugs that are not potent enough to quickly and completely inhibit viral replication. Drug-resistant mutant viruses, while initially low in number, eventually become the predominant strain in an infected patient as those strains that remain susceptible to the drug are inhibited from replicating. Once this occurs, the treatment benefit of that particular antiviral drug diminishes, resulting in treatment failure and the need for an alternate therapy with different or possibly new drugs, or classes of drugs. In general, viruses that cause chronic infections, such as HIV, are more likely to develop drug resistance due to the long-term and persistent exposure of the virus to the antiviral therapy.

What are Vaccines? Vaccines represent an approach to broaden the ability to prevent serious infectious diseases caused by both viruses and bacteria. A vaccine is a substance introduced into the human body that teaches the immune system to detect and destroy a pathogen (a virus or other pathogen that causes disease). All vaccines contain some harmless form or part of the pathogen they target or of a highly similar pathogen. They exert their effects through the adaptive immune response, an arm of the immune system that learns to recognize and control specific pathogens.

There are several types of vaccines:

● | Whole-killed/Whole-inactivated vaccines: The active ingredient in these vaccines is an intact virus or bacterium that has been killed or otherwise stripped of its ability to infect humans. Examples include the cholera and injectable polio vaccines. This approach has not been applied to the development of vaccines against HIV due to lack of success in animal experiments and the difficulty of developing an inactivation method capable of ensuring that the product will be entirely free of active virus. Similarly, inactivated Ebola vaccines have not shown great promise in animal models, and any production process starting with live Ebola or Marburg virus would require such extreme containment measures that it would be difficult to operate at industrial scale.

● | Live attenuated vaccines: These vaccines use a form of the targeted pathogen that is highly unlikely to be harmful—one capable, say, of multiplying, but not causing disease. Examples include the measles vaccine and the oral vaccine against polio, which has been widely deployed in global eradication efforts. Such vaccines can be very effective because they closely mimic the behavior of the targeted pathogen, giving the immune system a truer picture of what it would be up against. Due to the risk that attenuated HIV, Ebola, or Marburg might revert to its disease-causing form, this approach has not been applied to the development of HIV, Ebola, or Marburg vaccines.

● | Subunit vaccines: Vaccines of this variety are composed of purified pieces of the pathogen (known as antigens) that generate a vigorous, protective immune response. Common subunit vaccines include the seasonal flu and hepatitis B vaccines. This approach was employed to devise the first AIDS vaccine candidate tested in humans, which failed to induce protection from HIV infection. To date, subunit vaccines have failed to protect nonhuman primates against Ebola infection (Human Vaccines, 6:439 (2010)).

● | Purified VLP vaccines: Purified VLP vaccines consist only of virus-like particles, which are composed of certain viral proteins but do not contain the genetic material of the virus. Unlike subunit vaccines, VLPs typically provide viral antigens in their native form. Due to their structural similarity to actual viruses, VLPs are excellent immunogens capable of raising potent antibody and cellular immune responses. Purified VLPs need to be manufactured and purified in large quantities. They also are difficult to make for relatively fragile viruses with lipid membrane envelopes such as HIV, Ebola, or Marburg vaccines. Examples of successful vaccines using purified VLPs include vaccines for hepatitis B (Merck’s Recombivax® and GSK’s Engerix®) and Papilloma viruses (GSK’s Cervarix®, and Merck’s Gardasil®).

● | Expressed VLP vaccines: These vaccines are designed to produce self-assembling non-infectious VLPs in the cells of the person being vaccinated. When VLPs for enveloped viruses like HIV, Ebola, and Marburg are produced in vivo, they include not only the protein antigens, but also an envelope consisting of membranes from the vaccinated individual’s cells. In this way, they are highly similar to the virus generated in a person’s body during a natural infection. Purified VLPs produced externally, by contrast, have no envelope; or, envelopes from the cultured cells (typically hamster or insect cells) used to produce them. By producing VLPs in vivo, potential purification issues associated with in vitro production of VLPs are avoided. GeoVax employs this approach in our vaccine design.

● | DNA vaccines: These vaccine candidates are also designed to train the immune system to recognize a piece of the targeted bacterium or virus. The difference is that the active ingredients are not the purified antigens themselves but circles of DNA, called plasmids, which carry genes encoding those antigens. Human cells passively take up these plasmids and produce the antigens which, in turn, train the immune system to recognize the targeted pathogen.

● | Recombinant viral vaccines: These vaccines, like DNA vaccines, introduce genes for targeted antigens into the body. But the genes are inserted into a virus that actively infects human cells. The viruses chosen as vectors are safe to use because they do not ordinarily cause disease in humans and/or have been stripped of their ability to proliferate.

Our Ebola & Marburg Vaccine Program

About Ebola and Marburg. Ebola Hemorrhagic Fever (EHF) and the related disease Marburg Virus Disease (MVD) are highly contagious, extremely deadly diseases that, if not contained by quarantine, are capable of threatening populations worldwide. Since 1976, when Ebola was first discovered, at least 28 outbreaks have occurred. The 2014 Ebola outbreak in West Africa was significantly larger than any previous epidemic, the first to reach urban areas and the first to lead to person-to-person transmission in the United States. This outbreak resulted in approximately 28,600 infections with over 11,000 deaths (40% fatality rate). No approved preventive or therapeutic products exist for EHF or MVD.

Ebola and Marburg naturally infect animals including bats, creating reservoirs of Ebola and Marburg that, like rabies, cannot be completely eradicated. The rapid urbanization of many areas of Sub-Saharan Africa and the ease of modern air travel create conditions that facilitate the epidemic spread of EHF and MVD, which previously had been limited to localized outbreaks in villages. EHF is caused by ebolaviruses (Ebola), and MVD is caused by marburgviruses (Marburg). Ebola and Marburg are members of the family Filoviridae. Ebolaviruses are more diverse than marburgviruses and are divided into five subtypes: Zaire, Sudan, Bundibugyo, Tai Forest, and Reston. Zaire is the most lethal of the strains and is responsible for the current epidemic. Sudan and Bundibugyo are also lethal but have caused fewer and less severe outbreaks.

A challenge in Ebola and Marburg vaccine development is the need to create products that are effective both in containing an epidemic (in which rapid responses are critical) and in routine immunization (in which the duration of immunity is important). Ideal countermeasures to Ebola and Marburg would include a single-shot strain-specific epidemic vaccine capable of rapidly producing protective antibodies and T cells, and a routine vaccine capable of eliciting durable immunity to the lethal strains of Ebola (Zaire, Sudan and Bundibugyo) as well as Marburg. An effective vaccine against Ebola and/or Marburg would dramatically reduce the epidemic spread of infections as well as the transmission of Ebola and/or Marburg from natural animal hosts to humans.

Research on Ebola vaccines is progressing rapidly amongst a number of different pharmaceutical companies, with recombinant chimpanzee adenovirus (ChAd3), rare-serotype adenovirus (Ad26) and vesicular stomatitis virus (VSV) candidates already in clinical trials and several other vaccines scheduled to begin clinical trials. However, none of these vaccines has an ideal design, nor are any of them well suited for use in proactive immunization of populations to prevent future epidemics. The adenovirus vaccines require boosting with MVA to raise protective immune responses, and the two-product regimen (adenovirus and MVA) dramatically raises manufacturing costs and the complexity of vaccination. The replication competent VSV recombinants have already shown risk signals in the current trial, necessitating a temporary halt to the trial followed by resumption at a lower vaccine dose. The potential dose-limiting toxicity of the VSV vaccines raises safety concerns for large-scale vaccinations and also could pose threats to immunocompromised people, such as those infected with HIV. None of the competitors’ vaccines produce virus-like particles, a desirable characteristic, which is discussed in detail elsewhere in this document. To the best of our knowledge, no non-GeoVax vaccine candidates share this characteristic. One or more of the current candidates may well show success in stemming the current epidemic. However, the world must be prepared with the optimal vaccine for the next epidemic when it occurs. All of the vaccines currently in clinical trials are designed to protect against one, or at most two, strains of Ebola. To be successful, an optimal vaccine should be safe, effective, and long lasting, all at a reasonable cost. Our analysis suggests that the GeoVax designs are well suited to achieve this aim.

Our Vaccines. To address the unmet need for a product to prevent hemorrhagic fever viruses, we are developing a series of vaccines, which combine our proven MVA technology with advanced vaccine design. We are developing individual vaccines (monovalent) that will address each of the lethal strains of Ebola virus (Zaire, Sudan and Bundibugyo), as well as Marburg virus. We also are developing a multivalent vaccine, which will incorporate multiple monovalent vaccines to protect not only against current strains of filoviruses such as Ebola and Marburg, but also against other major hemorrhagic fever viruses endemic in African countries.

In April 2015, we entered into a Research Collaboration Agreement with the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, for development of our vaccines against Ebola and Marburg viruses. Under this agreement, NIAID is contributing materials, reagents, and scientific advice for vaccine construction, and has conducted animal protection studies in guinea pigs, and hamsters. In September, studies of our first Ebola vaccine candidate conducted pursuant to this collaboration demonstrated 100 percent protection in these small animal models. We plan to conduct additional animal challenge studies during 2016 with the goal of beginning human clinical trials during the first half of 2017. We intend to seek additional funding from U.S. government agencies and/or world health organizations to assist us in this regard.

17

We believe our Ebola/Marburg vaccines will demonstrate a unique combination of advantages that set them apart from any other products in development for prevention of EHF.

● | VLP immunogens. Our GEO-EM01 vector (the active component of the GOVX-E301 product) has been demonstrated to express noninfectious Ebola VLPs in human cells. VLPs mimic the structure of ebolavirus particles and display the vaccine antigens in conformations that are highly similar to those present in live virions. Our prior experience with VLP-expressing HIV vaccines, i.e., the best durability seen in the field of HIV vaccines, suggests that VLPs expressed by MVA raise highly durable antibody responses.

● | Expression of VLPs by a live vector. Unlike purified VLP vaccines, the GeoVax vaccines are intended to produce VLPs in the cells of the vaccinated person. This strategy carries several advantages. The live, VLP-expressing vector provides antigens in three different forms: as VLPs, as proteins on the surface of MVA-infected cells, and as proteins expressed within MVA-infected cells. Each type of antigen is recognized differently by the immune system, contributing to the breadth and potency of the immune response. Also, unlike VLPs produced in cell culture, the VLPs expressed by the GeoVax vaccines bud from the cells of the vaccinated person, just as infectious Ebola or Marburg would do if the person were exposed to the virus rather than the vaccine. In this way, the VLPs produced in the cells of the vaccinated person are structurally more similar to actual Ebola or Marburg virions. This structural similarity focuses the immune response on the actual antigens of interest rather than eliciting responses against antigens in non-native forms or irrelevant proteins from the membranes of cultured cells.

● | The excellent safety of MVA. Our vaccines use the MVA vector, which is highly attenuated. Originally developed as a safer alternative to vaccinia, MVA has shown excellent safety in over 120,000 human subjects. It is widely recognized as a safe vector for recombinant vaccines and has been shown to be safe in immunocompromised individuals and in SIV (the primate version of HIV) infected macaques. The attenuation of MVA allows it to be used in high doses, potentially enabling a protective single-dose regimen in an epidemic situation. Though two other competitive MVA vectors do not express VLPs and are components of other vaccines in clinical development, these other MVA vectors are used in combination with novel adenovirus vectors, which have only limited safety data in humans.

● | The ability of MVA to raise antibody and T-cell responses. The field of Ebola immunology is developing rapidly, and researchers have not yet reached a solid consensus on a correlate of protection. Recent studies, including anecdotal results from passive antibody therapy of infected patients, point toward neutralizing antibody as the most important immune response. However, certain animal challenge studies have suggested that binding (rather than neutralizing) antibody correlates best with protection, and other studies have indicated T-cell responses are critical for clearing infections. MVA-vectored vaccines are very efficient at raising both antibody and T-cell responses.

● | Antigens against the current epidemic. A vaccine will be most effective if it provides antigens as similar as possible to those in circulating strains of the pathogen. For this reason, we have designed our Zaire ebolavirus vaccines against a genetic sequence from the current epidemic. In this way, our product maximizes the probability of delivering a vaccine antigen that is as close as possible to the circulating pathogen.

● | Rapid induction of responses. The MVA vector is highly effective at raising protective responses quickly. Vaccinia, the parental vector for MVA, was used successfully in immunization of people who had come in contact with smallpox-infected individuals. This fact and results from GeoVax’s HIV trials suggest that the GeoVax Ebola and Marburg vaccines should be well-suited to epidemic situations in which a protective response must be raised quickly.

● | Homologous prime-boost regimen. Published data indicate that, while a single immunization may be sufficient to provide short-term protection in an epidemic situation, a multiple-dose strategy is often superior for raising the durable responses that are required in routine preventive vaccination campaigns. Our MVAs are designed to be used in homologous prime-boost regimens, in which multiple doses of the same vaccine are given. The homologous prime-boost strategy is simpler and more economical than heterologous prime-boost products such as the adenovirus-MVA combinations currently being tested. Relative to a product that requires a heterologous prime-boost regimen, our MVAs should be simpler and less expensive to manufacture, test, distribute, and use.

● | Experience with the use of MVA in prime-boost regimens. MVAs are highly effective at boosting immune responses, as demonstrated in previous work on Ebola as well as preclinical and clinical trials of HIV vaccines. Our results with MVA prime-boost regimens in HIV trials suggest that MVA alone is highly effective (more effective than DNA and MVA combined) at raising antibody responses. For this reason, we believe that the MVA-MVA prime-boost strategy will be ideal for routine vaccination of populations with our GOVX-E301 product. Also, though we have no current plans to develop our MVAs as boosts for other vaccines, we recognize that any of our MVAs could potentially be used as a heterologous boost to a different (for example, adenovirus) priming vaccine if future data indicate that a heterologous regimen is desirable.

18

● | The excellent thermal stability of MVA. To be appropriate for use in remote regions of the world, a vaccine must be stable enough to remain potent despite suboptimal cold chain logistics. In addition, to be suitable for storage in national stockpiles, Ebola vaccines must remain stable over several years of storage. MVA vaccines are highly stable in both liquid and lyophilized dosage forms. An ongoing stability study of our MVA vaccine against HIV has shown excellent stability over more than six years of storage.

● | Manufacturability of MVA-vectored vaccines. If designed with genetically stable inserts, MVA-vectored vaccines can reliably be manufactured in large quantities. In addition to the established Chick Embryo Fibroblast (CEF) cell substrate, we have also investigated novel continuous cell lines for manufacture of our vaccines against HIV, and believe they could potentially be used for manufacture of our MVA vaccines against Ebola. Continuous cell lines offer virtually unlimited scalability as well as greater process consistency and efficiency.

Our HIV/AIDS Vaccine Program

About HIV/AIDS. HIV is a retrovirus that carries its genetic code in the form of RNA. Retroviruses use RNA and the reverse transcriptase enzyme to create DNA from the RNA template. The HIV-1 virus enters human cells and copies its viral RNA to produce complementary DNA (cDNA) that is subsequently inserted into the chromosomes, which are the genetic material of a cell. HIV preferentially infects and replicates in T-cells, which are a type of white blood cell. Infection of T-cells alters them from immunity mediating cells to cells that produce and release HIV. This process results in the destruction of the immune defenses of infected individuals and ultimately, the development of AIDS.

There are several AIDS-causing HIV virus subtypes, or clades, that are found in different regions of the world. These clades are identified as clade A, clade B and so on. The predominant clade found in Europe, North America, parts of South America, Japan and Australia is clade B, whereas the predominant clades in Africa are clades A and C. In India, the predominant clade is clade C. Each clade differs by at least 20% with respect to its genetic sequence from other clades. These differences may mean that vaccines or treatments developed against HIV of one clade may only be partially effective or ineffective against HIV of other clades. Thus, there is often a geographical focus to designing and developing HIV vaccines.

HIV, even within clades, has a high rate of mutation that supports a significant level of genetic variation. In drug treatment programs, virus mutation can result in the development of drug resistance, referred to as virus drug escape, thereby rendering drug therapy ineffective. Hence, we believe that multi-drug therapy is very important. If several drugs are active against virus replication, the virus must undergo multiple simultaneous mutations to escape, which is less likely. The same is true for immune responses. HIV can escape single targeted immune responses. However, our scientists believe if an immune response is directed against multiple targets, which are referred to as epitopes, virus escape is much less frequent. Vaccination against more than one of the proteins found in HIV increases the number of targets for the immune response as well as the chance that HIV will not escape the vaccine-stimulated immune response, thus resulting in protection against infection or the development of clinical AIDS if infection occurs.

HIV infects and gradually destroys T-cells and macrophages, which are white blood cells that play key roles in protecting humans against infectious disease caused by viruses, bacteria, fungi and other micro-organisms. Opportunistic infections by organisms, normally posing no problem for control by a healthy immune system, can ravage persons with immune systems damaged by HIV infections. Destruction of the immune system occurs over years. The average onset of the clinical disease recognized as AIDS occurs after three to ten years of HIV infection if the virus is not treated effectively with drugs, but the time to developing AIDS is highly variable.

AIDS is considered by many in the scientific and medical community to be the most lethal infectious disease in the world. An estimated 37 million people are living with HIV worldwide, with approximately 2.5 million newly infected in 2012 alone. Approximately 39 million people infected with HIV have died since the 1981 start of the HIV pandemic. The United States currently has an estimated 1.2 million HIV-infected individuals, with approximately 50,000 new infections per year.

At present, the standard approach to treating HIV infection is to inhibit viral replication through the use of combinations of drugs. Available drugs include reverse transcriptase inhibitors, protease inhibitors, integration inhibitors and inhibitors of cell entry to block multiple essential steps in virus replication. However, HIV is prone to genetic changes that can produce strains that are resistant to currently approved drugs. When HIV acquires resistance to one drug within a class, it can often become resistant to the entire class, meaning that it may be impossible to re-establish control of a genetically altered strain by substituting different drugs in the same class. Furthermore, these treatments continue to have significant limitations which include toxicity, patient non-adherence to the treatment regimens and cost. As a result, over time, viruses acquire drug-resistant mutations, and many patients develop intolerance to the medications or simply give up taking the medications due to the side effects.

19

According to the International AIDS Vaccine Initiative (IAVI), the cost and complexity of new treatment advances for AIDS puts them out of reach for most people in the countries where treatment is most needed. As noted above, in industrialized nations, where drugs are more readily available, side effects and increased rates of viral resistance have raised concerns about their long term use. AIDS vaccines, therefore, are seen by many as the most promising way to end the HIV/AIDS pandemic. It is expected that vaccines for HIV/AIDS, once developed, will be used universally and administered worldwide by organizations that provide health care services, including hospitals, medical clinics, the military, prisons and schools.

Our Preventive HIV Vaccine Program

Prevention of HIV infection remains a worldwide unmet medical need, even in the United States and other first world countries where effective antiretroviral therapies are available. There is no approved HIV vaccine. Current antiretroviral therapies do not eliminate HIV infection, requiring individuals to remain on antiretroviral drugs for their entire lives. In the United States, it is estimated that of the 1.2 million infected individuals, for various reasons (lack of diagnosis, linkage to care, patient compliance, etc.) only 25% ultimately remain in HIV care with their viral load sufficiently suppressed to prevent spread of HIV. As a result, the annual incidence of new HIV infections has remained virtually unchanged for the past 20 years. Furthermore, the annual financial burden to the U.S. taxpayer for HIV education, prevention, and treatment costs borne through multiple federal agencies is more than $20 billion annually.

Work on our HIV vaccines began during the 1990s at Emory University in Atlanta, Georgia, under the direction of Dr. Harriet L. Robinson, who is now our Chief Scientific Officer. The vaccine technology was developed in collaboration with researchers at the NIH and the CDC.

Our most clinically advanced vaccine development program is a DNA/MVA vaccine regimen designed to protect against the clade B subtype of the HIV virus. Clade B is prevalent in the Americas and Western Europe. An estimated 3.3 million people are infected with clade B HIV virus worldwide, with 187,000 new infections in 2012.

We have two HIV vaccine components under development: a recombinant DNA vaccine, and a recombinant MVA vaccine. Both the DNA and MVA vaccines contain sufficient HIV genes to support the production of non-infectious virus-like particles. These VLPs display the native trimeric membrane-bound form of the HIV envelope glycoprotein (Env) that mediates entry into cells and is the target for protective antibody. When used together, the recombinant DNA component primes immune responses, which are boosted by administration of the recombinant MVA component. This prime-boost strategy elicits high avidity antibodies (tightly binding antibodies) and cytotoxic T cells. The antibodies can block infections and initiate the killing of virus and infected cells by bound antibody signaling destruction by virion capture, antibody-dependent cellular cytotoxicity, phagocytosis and complement mediated lysis. We may also pursue development of our MVA vaccine component as a standalone HIV vaccine, or in combination with other vaccine components.

Clinical trials of our preventive HIV vaccine have been conducted by the HIV Vaccine Trials Network (HVTN). The HVTN is the largest worldwide clinical trials network dedicated to the development and testing of HIV/AIDS vaccines. Support for the HVTN comes from the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH. The HVTN’s HIV Vaccine Trial Units are located at leading research institutions in 27 cities on four continents.

We have completed multiple Phase 1 trials and a Phase 2a trial (HVTN 205) of various dosing regimens and formulations of our vaccines. These vaccines have been evaluated in nearly 500 humans. All of the clinical trials of our preventive vaccines have been conducted by the HVTN, and fully funded by the NIH.

We also expect the NIH to fully fund the cost of another Phase 1 trial (HVTN 114) of our preventive HIV vaccine to begin in early 2016, which will investigate the effect of adding a “protein boost” component to our vaccine. Protein boosts may augment antibody responses that can block virus infections (neutralizing antibody) and cause antibody dependent cellular cytotoxicity (ADCC antibody). Proteins added to HIV vaccines have shown some success in other trials. The HVTN believes this “dual-action” approach will be a prudent and cost-effective path forward for supporting large clinical trials. Information from this trial would then inform the design of future, larger clinical trials. While efforts are underway to evaluate the protein boost concept, we also intend to seek funding to expedite our vaccine (without the additional protein boost) directly into pivotal Phase 2b efficacy trials.

The HVTN is continuing to consider future efficacy studies, and members are working to develop collaborative clinical development plans, as well as initiating regulatory planning. The plans for large-scale clinical trials may change as researchers continue to gather information from our earlier studies and are influenced by results from other vaccine trials. Trial start dates are dependent on many factors and are likely to change.

20

Preventive HIV Vaccine Program – Clade C. We also plan to develop vaccines designed for use to combat the subtypes of HIV that predominate in the developing countries. We have licensed from the U.S. National Institutes of Health (NIH) the modified vaccine Ankara (MVA) construct for the clade C subtype of HIV prevalent in South Africa and India, and we have completed lead discovery using a novel approach to vaccination against clade C. We have performed initial process development studies for the NIH-developed vaccine and initiated early development work on the other, newer clade C vaccine. Depending on the results of animal studies and the focus of future government support, we may advance either or both of the clade C vaccines into the clinic. In June 2015, the NIH awarded us a Small Business Innovative Research (SBIR) grant entitled “Directed Lineage Immunizations for Eliciting Broadly Neutralizing Antibody” toward this effort. The initial grant award of $299,585 is for the first year of a two year project period beginning July 1, 2015.

Preclinical Studies. We conducted preclinical efficacy trials of our preventive HIV vaccines by vaccinating non-human primates with simian immunodeficiency virus prototypes of our HIV vaccines and then testing them for resistance to simian immunodeficiency virus infection. The experimental data produced by these trials documented the ability of the simian prototypes of our vaccines to induce immune responses that can prevent infection as well as reduce the levels of viral replication in those animals that become infected.

Completed Human Clinical Trials -- Preventive HIV Vaccine

Phase 1 Human Clinical Trials. All of our preventive vaccination trials in humans have been conducted by the HVTN, a network that is funded and supported by the NIH. The HVTN is the largest worldwide clinical trials network focused on the development and testing of HIV/AIDS vaccines. The results of a two group, 30 participant, Phase 1 trial (designated HVTN 045) are published in AIDS RESEARCH AND HUMAN RETROVIRUSES 22:678 (2006) and of a four group 120 participant trial (HVTN 065) in The Journal of Infectious Diseases 203:610 (2011). Our Phase 1 trials have tested both safety and dosing regimens.

In our first Phase 1 clinical trial, HVTN 045, our DNA vaccine was tested without MVA boosting to document the safety of the DNA. Our second Phase 1 clinical trial, HVTN 065, was designed to test the combined use of DNA and MVA and consisted of a dose escalation as well as regimen studies. The low dose consisted of 0.3 mg of DNA and 1x107 tissue culture infectious doses (TCID50) of MVA. Once safety was demonstrated for the low dose in 10 participants, the full dose (3 mg of DNA and 1x108 TCID50 of MVA) was administered to 30 participants. A single dose of DNA at time 0 followed by MVA at weeks 8 and 24, a DMM regimen, and three doses of MVA administered at weeks 0, 8 and 24, an MMM regimen, were also tested in 30 participants each. Participants were followed for 12 months to assess vaccine safety and to measure vaccine-induced immune responses.

Data from the HVTN 065 trial again documented the safety of the vaccine products but also showed that the DDMM and MMM regimens induced different patterns of immune responses. The full dose DDMM regimen induced higher response rates of CD4++ T-cells (77%) and CD8++ T-cells (42%) compared to the MMM regimen (43% CD4+ and 17% CD8+ response rates). In contrast, the highest response rates and highest titers of antibodies to the HIV Env protein were induced in the group that received only the MVA using the MMM regimen. Antibody response rates were documented to be higher for the MMM group using three different assays designed to measure total binding antibody levels for an immune dominant portion of the Env protein (27% for DDMM and 75% for MMM), binding of antibodies to the gp120 subunit of the envelope glycoprotein (81% for DDMM and 86% for MMM) and neutralizing antibodies (7% for DDMM and 30% for MMM). The 1/10th dose DDMM regimen induced overall similar T-cell responses but reduced antibody responses while the response rates were intermediate in the DMM group.

The HVTN also sponsored and conducted a Phase 1 clinical trial in humans (HVTN 094) of the adjuvanted form of our vaccine that co-expresses GM-CSF in the DNA priming vaccine. We have designated the GM-CSF-adjuvanted version of our DNA/MVA vaccine regimen as GOVX-B21, and the unadjuvanted version as GOVX-B11. During December 2013, we reviewed preliminary results from HVTN 094. Based on excellent preclinical non-human primate data, this trial was originally initiated with the expectation that GOVX-B21 would be carried forward into Phase 2 testing by the HVTN, with support by the NIH. However, comparison of data between HVTN 094 and the Phase 2a trial, HVTN 205 (see below) did not show a significant benefit from adding the adjuvant to the vaccine for preventive use; therefore GOVX-B21 was not advanced in further clinical testing (results to be published).

21

Phase 2 Human Clinical Trials. Based on the safety and the immunogenicity results in the HVTN 045 and HVTN 065 trials, the full dose DNA/MVA and MVA-only regimens were selected for testing by the HVTN in a Phase 2a trial (designated HVTN 205) which was completed in 2012 and the subject of an oral presentation at the AIDS Vaccine 2012 Conference in September 2012, with further analysis presented at the AIDS Vaccine Meeting in Barcelona, Spain, in October 2013 and a publication in the Journal of Infectious Diseases (volume 210, pg 99) in 2014. HVTN 205 was designed to evaluate the safety and immunogenicity of our vaccines in healthy, HIV-uninfected adults. In HVTN 205, 299 participants were randomly assigned to three study arms: 149 participants received two injections of our DNA vaccine followed by two injections of our MVA vaccine (DDMM arm), 75 participants received three MVA injections and one placebo injection (MMPM arm), and 75 participants received four injections of placebo. After the final vaccination, antibody responses against the HIV Envelope protein (Env), the target for protective antibody, were detected in 93.2% of the DDMM arm (the vaccination regimen selected for further clinical study). At six months after final vaccination (the latest time point tested), gp140 IgG antibody response titers in the DDMM arm had declined by less than 3-fold, with response rates only declining from 100% to 84%, indicating significant durability of the antibody response. Additionally, HVTN 205 also showed that the antibody responses after vaccination had high affinity binding, a characteristic which has been associated with prevention of HIV infection in preclinical models. The study also showed low response rates for serum IgA, a desirable characteristic because serum IgA competed with serum IgG for reducing the risk of infection in the one partially protective (31%) AIDS vaccine trial in Thailand. Response rates for serum IgG3, an isotype associated with activating innate methods of protection such as complement (C’)-mediated lysis and antibody-dependent cellular cytotoxicity were excellent (91%).

HIV Immunotherapy Program

Current antiretroviral therapies, though highly effective at suppressing HIV viral load, are unable to eliminate HIV infection entirely. A major challenge in the development of HIV therapeutics is the ability of HIV to persist in host cells in a latent proviral form, invisible to the immune system and inaccessible to antiretroviral drugs. In response to this problem, the NIH and other leaders in the HIV field have developed a new concept: the “shock and kill” strategy, in which patients remain on standard-of-care anti-retroviral drug therapy while a second drug (“shock agent”) is used to activate latent HIV and a third drug (“kill agent”) is used to recognize and eliminate cells that harbor the latent HIV reservoir. A shock and kill therapy could potentially contribute to a cure for HIV.

Observations from a pilot Phase 1 clinical trial of our HIV vaccines (GV-TH-01 – discussed below) have led us to postulate that our DNA vaccines may be effective as a shock agent and that a subsequent, precisely timed MVA inoculation may reduce viral reservoirs. The Company is currently considering the best course of action for advancing its HIV immunotherapy program. Future therapeutic studies of GeoVax’s vaccine may investigate vaccine’s ability to act as a “shock agent” in a shock and kill therapy in combination with standard of care antiretroviral drug therapy to seek a cure. The timetable and specific clinical plans will be dependent upon the Company’s ability to secure external funding for the program, and on the nature of any potential collaborations GeoVax may establish.

Preclinical Studies – Therapeutic Vaccine. In 2007-2008, data were generated in three pilot studies on therapeutic vaccination in simian immunodeficiency virus-infected non-human primates. The vaccine used in these pilot studies was specific for simian immunodeficiency virus but with the design features of our HIV/AIDS vaccine. In these pilot studies, conducted at Yerkes National Primate Research Center of Emory University, non-human primates were infected, drug-treated, vaccinated and then drug-interrupted. Following treatment interruption, median levels of virus in blood, measured as viral RNA, were 10 to 1000-times lower than those measured prior to drug and vaccine treatment. The therapeutic reductions in virus levels were best for animals placed on drugs within 12 weeks of infection with lower levels of protection being achieved in animals that were placed on drugs at 3 months or later after infection.

Phase 1 Trial (Treatment Interruption). In early 2014, we completed a Phase 1 clinical trial (GV-TH-01) investigating the therapeutic use of our vaccines in HIV-infected patients. GV-TH-01 is an open label Phase 1 treatment interruption trial investigating the safety and immunogenicity of our DNA/MVA vaccine regimen in 9 HIV-infected patients who initiated drug treatment within 18 months of seroconversion and had stably controlled virus for at least 6 months. Patients were vaccinated with two DNA inoculations followed by two MVA inoculations at intervals of two months. Eight weeks following the last inoculation, patients suspended drug therapy for a 12-week period. Vaccinated patients’ ability to control the time and temporal height of re-emergent virus in the absence of drugs was then observed. Drug treatment was re-instituted after 12 weeks, and trial participants were observed for an additional 6 months. The primary endpoint of this study was to evaluate the safety of our vaccine in HIV-positive patients with well-controlled infections who are being treated with oral HIV medications. An exploratory objective of the study was to evaluate the ability of the vaccinated patient to control re-emergent virus during the drug treatment interruption period.

Analysis of GV-TH-01 data indicates that, during the vaccination phase of the trial, enhanced CD8++ T cells were elicited in 8 of 9 participants and enhanced CD4++ T cell in 5 of 9 participants. Antibody responses were boosted in 4 of 9 participants. Analyses during the treatment interruption phase of the trial suggested that individuals with the best immune responses had lower levels of re-emergent virus. These levels however were not sufficiently low to prevent immune escape and the reinstitution of progression towards AIDS. Excellent safety was observed throughout the trial, with none of the participants needing to reinstate antiretroviral drugs during the treatment interruption phase of the trial (data being compiled for publication).

Support from the United States Government

With the exception of the GV-TH-01 Phase 1 therapeutic trial (treatment interruption protocol), all of our human clinical trials to date have been conducted by the HVTN and funded by NIH. This financial support has been provided by the NIH directly to the HVTN, so has not been recognized in our financial statements. Our responsibility for these clinical trials has been to provide sufficient supplies of vaccine materials and technical expertise when necessary.

In addition to clinical trial support from the NIH, our operations have been partially funded by NIH research grants. Refer to our Financial Statements beginning on page F-1 of this Prospectus, and to “Management's Discussion and Analysis of Financial Condition and Results of Operations”, for additional information regarding revenue and funds availability from these grants.

Regulations

Regulation by governmental authorities in the United States and other countries is a significant factor in our ongoing research and development activities and in the manufacture of our products under development. Complying with these regulations involves considerable time and expense.

In the United States, drugs are subject to rigorous federal and state regulation. Our products are regulated under the Federal Food, Drug and Cosmetic Act, as amended (FD&C Act), and the regulations promulgated thereunder, and other federal and state statutes and regulations. These laws govern, among other things, the testing, manufacture, safety, efficacy, labeling, storage, record keeping, approval, advertising and promotion of medications and medical devices. Product development and approval within this regulatory framework is difficult to predict, takes a number of years and involves great expense. The steps required before a human vaccine may be marketed in the United States include:

| ● | pre-clinical laboratory tests, in vivo pre-clinical studies and formulation studies;

| ● | manufacturing and testing of the product under strict compliance with current Good Manufacturing Practice (cGMP) regulations;

| ● | the submission to the FDA of an Investigational New Drug (IND) application for human clinical testing which must become effective before human clinical trials can commence;

| ● | adequate and well-controlled human clinical trials to establish the safety and efficacy of the product;

| ● | the submission of a Biologics License Application to the FDA, along with the required user fees;

| ● | FDA approval of the Biologics License Application prior to any commercial sale or shipment of the product; and

| ● | postmarketing requirements imposed by FDA.

Each of these steps is described further below. Before marketing any drug or biologic for human use, the product sponsor must obtain FDA approval. In addition, each manufacturing establishment must be registered with the FDA and must pass a Pre-Approval Inspection (PAI) before introducing any new drug or biological product into commercial distribution. Because GeoVax does not manufacture vaccines for human use within our own facilities, we must ensure compliance both in our own operations and in the outsourced manufacturing operations. All FDA-regulated manufacturing establishments (both domestic establishments and foreign establishments that export products to the United States) are subject to inspections by the FDA and must comply with the FDA’s Good Manufacturing Practices for products, drugs and devices.

FDA determines compliance with applicable statutes and regulations through documentation review, investigations, and inspections. Several enforcement mechanisms are available to FDA, ranging from a simple demand to correct a minor deficiency to mandatory recalls, closure of facilities, and even criminal charges for the most serious violations.

Preclinical Testing. Preclinical testing includes laboratory evaluation of chemistry and formulation, as well as cell culture and animal studies to assess the safety and potential efficacy of the product. Preclinical safety tests and certain other pivotal preclinical studies must be conducted by laboratories that comply with the FDA’s Good Laboratory Practices, or GLP. The results of pre-clinical testing are submitted to the FDA as part of the IND application and are reviewed by the FDA prior to the commencement of human clinical trials. Unless the FDA objects to an IND, the IND becomes effective 30 days following its receipt by the FDA.

23

cGMP-Compliant Manufacturing and Testing. FDA has issued, and frequently updates, extensive regulations on current Good Manufacturing Practice (cGMP). Any drug, biologic, or device for human use, whether commercial or investigational, must be manufactured under these regulations. cGMP regulations include a wide variety of requirements covering personnel, documentation, facilities, equipment, testing procedures, and many other aspects of manufacturing and testing.

Clinical Trials. Clinical trials involve the administration of investigational drugs to volunteers or to patients under the supervision of a qualified, medically trained clinical investigator. Clinical trials are conducted in accordance with Good Clinical Practices under protocols that detail the objectives of the trial, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Each protocol and the qualifications of the investigators who plan to carry it out must be submitted to the FDA as part of the IND. Further, each clinical trial must be conducted under the auspices of an independent institutional review board at the institution where the trial will be conducted. The institutional review board will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution.

Clinical trials are typically conducted in three sequential phases, but the phases may overlap. In the Phase 1 clinical trial, the initial introduction of the product into healthy human subjects, the vaccine is tested for safety (including adverse side effects) and dosage tolerance. The Phase 2 clinical trial is the proof of principal stage and involves trials in a limited patient population to determine whether the product induces the desired effect (for our vaccines this means immune responses) and to better determine optimal dosage. The continued identification of possible safety risks is also a focus. When there is evidence that the product may be effective and has an acceptable safety profile in Phase 2 clinical trials, Phase 3 clinical trials are undertaken to evaluate clinical efficacy and to test for safety within an expanded patient population. Phase 3 trials are completed using multiple clinical study sites which are geographically dispersed. The manufacturer or the FDA may suspend clinical trials at any time if either believes that the individuals participating in the trials are being exposed to unacceptable health risks.

Biologics License Application and FDA Approval Process. The results and details of the pre-clinical studies and clinical trials are submitted to the FDA in the form of a Biologics License Application (BLA), which is equivalent to the New Drug Application (NDA) submitted by companies seeking to market new drugs. If the BLA is approved, the manufacturer may market the product in the United States. Under the Prescription Drug User Fee Act (PDUFA), FDA charges user fees to applicants to offset the costs of its operations. The PDUFA user fee for a new vaccine is over $2 million, unless the applicant obtains a waiver or reduction through certain programs designed to encourage development of certain types of products.

Postmarketing Requirements. FDA frequently imposes postmarketing requirements as a condition of NDA or BLA approval. Common postmarketing requirements include additional clinical trials (Phase 4 trials) or observational studies. Postmarketing requirements are especially relevant to our Ebola and Marburg vaccines. We intend to pursue approval of these vaccines using the accelerated approval process, in which FDA grants approval based on performance against a criterion other than actual protection against the disease but requires the manufacturer to monitor and submit data on efficacy of the approved product. Unlike pathogens such as human papillomavirus, Ebola and Marburg are not constantly in circulation; instead, they occur in sporadic but extremely deadly outbreaks. For this reason, it would be impractical and potentially unethical to attempt to perform a traditional Phase 3 trial in which vaccinated participants are compared against unvaccinated participants to determine the efficacy of the vaccine in preventing infection with Ebola or Marburg. The accelerated approval process allows FDA to approve a new medicine based on its performance against a surrogate endpoint (in the case of Ebola or Marburg, its performance in raising immune responses). We anticipate that, as a condition of receiving accelerated approval, GeoVax would agree to monitor the real-world performance of our Ebola and Marburg vaccines.

International Approval. Whether or not the FDA has approved the drug, approval of a product by regulatory authorities in foreign countries must be obtained prior to the commencement of commercial sales of the drug in such countries. The requirements governing the conduct of clinical trials and drug approvals vary widely from country to country, and the time required for approval may be longer or shorter than that required for FDA approval.

Other Regulations. In addition to FDA regulations, our business activities may also be regulated by the Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and other present and potential future federal, state or local regulations. Violations of regulatory requirements at any stage may result in various adverse consequences, including regulatory delay in approving or refusal to approve a product, enforcement actions, including withdrawal of approval, labeling restrictions, seizure of products, fines, injunctions and/or civil or criminal penalties. Any product that we develop must receive all relevant regulatory approvals or clearances before it may be marketed.

24

Manufacturing

We do not have the facilities or expertise to manufacture any of the clinical or commercial supplies of any of our products. To be successful, our products must be manufactured in commercial quantities in compliance with regulatory requirements and at an acceptable cost. To date, we have not commercialized any products, nor have we demonstrated that we can manufacture commercial quantities of our product candidates in accordance with regulatory requirements. If we cannot manufacture products in suitable quantities and in accordance with regulatory standards, either on our own or through contracts with third parties, it may delay clinical trials, regulatory approvals and marketing efforts for such products. Such delays could adversely affect our competitive position and our chances of achieving profitability. We cannot be sure that we can manufacture, either on our own or through contracts with third parties, such products at a cost or in quantities that are commercially viable.

We currently rely and intend to continue to rely on third-party contract manufacturers to produce vaccines needed for research and clinical trials. We have entered into arrangements with third party manufacturers for the supply of our DNA and MVA vaccines for use in our planned clinical trials. These suppliers operate under the FDA’s Good Manufacturing Practices and (in the case of European manufacturers) similar regulations of the European Medicines Agency. We anticipate that these suppliers will be able to provide sufficient vaccine supplies to complete our currently planned clinical trials. Various contractors are generally available in the United States and Europe for manufacture of vaccines for clinical trial evaluation, however, it may be difficult to replace existing contractors for certain manufacturing and testing activities and costs for contracted services may increase substantially if we switch to other contractors.

Development of Improved Manufacturing Techniques for MVA – The MVA component of our vaccine is currently manufactured in cells that are cultured from embryonated chicken eggs, which is a reliable method to manufacture large quantities of vaccine. In an attempt to find a means to reduce costs for large-scale manufacturing, we have explored a number of approaches to producing MVA in continuous cell lines that can be grown in bioreactors. In this process we have identified a duck stem-cell-derived line (termed EB66), that is proprietary to Valneva S.E., France. We are currently working with Valneva on the use of EB66 cells for the growth of our MVA vaccines. We are hopeful that upon completion of this alternative process we will have the option of producing vaccine at significantly higher titers in a much more advanced and scalable process, allowing for quality improvements over the current process as well as meaningful cost reductions.

Competition

The biopharmaceutical industry and the vaccine market is competitive and subject to rapid and substantial technological change. Developments by others may render our proposed vaccination technologies noncompetitive or obsolete, or we may be unable to keep pace with technological developments or other market factors. Technological competition in the industry from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase. Many of the pharmaceutical companies that compete with us have significantly greater research and development capabilities than we have, as well as substantially more marketing, manufacturing, and financial resources. In addition, acquisitions of, or investments in, small pharmaceutical or biotechnology companies by such large corporations could increase their research, financial, marketing, manufacturing and other resources. Competitive technologies may ultimately prove to be safer, more effective or less costly than any vaccine that we develop.

There are currently no FDA licensed and commercialized Ebola vaccines, Marburg vaccines, or HIV vaccines available in the world market. We are aware of several development-stage and established enterprises, including major pharmaceutical and biotechnology firms, which are actively engaged in vaccine research and development in these areas. For Ebola, these include Johnson & Johnson, GlaxoSmithKline, and Merck. For HIV, these include Novartis, Sanofi-Aventis and GlaxoSmithKline. Other HIV vaccines are in varying stages of research, testing and clinical trials including those supported by the NIH Vaccine Research Center, the U.S. Military, IAVI, the European Vaccine Initiative, and the South African AIDS Vaccine Initiative. We may also experience competition from companies that have acquired or may acquire technologies from companies, universities and other research institutions. As these companies develop their technologies, they may develop proprietary technologies which may materially and adversely affect our business.

If any of our competitors develop products with efficacy or safety profiles significantly better than our products, we may not be able to commercialize our products, and sales of any of our commercialized products could be harmed. Some of our competitors and potential competitors have substantially greater product development capabilities and financial, scientific, marketing and human resources than we do. Competitors may develop products earlier, obtain FDA approvals for products more rapidly, or develop products that are more effective than those under development by us. We will seek to expand our technological capabilities to remain competitive; however, research and development by others may render our technologies or products obsolete or noncompetitive, or result in treatments or cures superior to ours.

25

Our competitive position will be affected by the disease indications addressed by our product candidates and those of our competitors, the timing of market introduction for these products and the stage of development of other technologies to address these disease indications. For us and our competitors, proprietary technologies, the ability to complete clinical trials on a timely basis and with the desired results, and the ability to obtain timely regulatory approvals to market these product candidates are likely to be significant competitive factors. Other important competitive factors will include the efficacy, safety, ease of use, reliability, availability and price of products and the ability to fund operations during the period between technological conception and commercial sales.

Our Intellectual Property

We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary rights are described by valid and enforceable patents or are effectively maintained as trade secrets. Accordingly, we are pursuing and will continue to pursue patent protection for our proprietary technologies obtained or developed through our collaborations with Emory University, the NIH, and the CDC, or developed by us alone. Our patent portfolio, described more fully below, includes claims directed to DNA and MVA based HIV vaccines, their genetic inserts expressing multiple HIV protein components, composition, structure, claim of immunization against multiple subtypes of HIV, routes of administration, safety and other related factors and methods of therapeutic and prophylactic use thereof including administration regimes. Also included are claims directed to preventive vaccines against Ebola and Marburg viruses and use thereof. As of January 1, 2015, we are the licensee of at least eight issued or allowed U.S. patents and at least 12 issued or allowed non-U.S. patents. We are actively pursuing one U.S. provisional application and one international patent application as the owner of record, in addition to at least six U.S. patent applications and at least 15 non-U.S. patent applications in six jurisdictions under license.

We are the exclusive, worldwide licensee of a number of patents and patent applications, which we refer to as the Emory Technology, owned, licensed or otherwise controlled by Emory University for HIV or smallpox vaccines pursuant to a License Agreement originally entered into on August 23, 2002 and restated on June 23, 2004, which we refer to as the Emory License. Through the Emory License we are also a non-exclusive licensee of four issued United States patents owned by the NIH related to the ability of our MVA vector vaccine to operate as a vehicle to deliver HIV virus antigens, and also to induce an immune response in humans. The four issued United States patents owned by the NIH expire in 2023. All of our obligations with respect to the HIV NIH-owned MVA patents are covered by the Emory License. The Emory License expires on the expiration date of the last to expire of the patents licensed thereunder including those that are issued on patents currently pending. We will not know the final termination date of the Emory License until such patents are issued. The Company may terminate the Emory University License upon 90 days’ written notice. The Emory License also contains standard provisions allowing Emory University to terminate upon breach of contract by the Company or upon the Company’s bankruptcy.

The Emory License, among other contractual obligations, requires payments based on the following:

● | Milestone Payments. An aggregate of $3,450,000 is potentially due to Emory University in the future upon the achievement of clinical development and regulatory approval milestones as defined in the Emory License. To date, we have paid a nominal milestone fee upon entering Phase 2 clinical trials for our preventive HIV/AIDS vaccine.

● | Maintenance Fees. The Company has achieved the specified milestones and met its obligations with regard to the related payments, and no maintenance fees are (or will be) owed to Emory University.

● | Royalties. Upon commercialization of products covered by the Emory License, we will owe royalties to Emory University of between 5% and 7.5%, depending on annual sales volume, of net sales made directly by GeoVax. The Emory License also requires minimum annual royalty payments of $3 million in the third year following product launch, increasing annually to $12 million in the sixth year.

● | Sublicense Royalties. In the event that we sublicense a covered product to a third party, we will owe royalties to Emory University based on all payments, cash or noncash, that we receive from our sublicensees. Those royalties will be 19% of all sublicensing consideration we receive prior to the first commercial sale of a related product. Commencing with the first commercial sale, the royalty owed to Emory University will be 27.5% of all sublicensing consideration we receive.

● | Patent Reimbursements. During the term of the Emory License, we are obligated to reimburse Emory University for ongoing third party costs in connection with the filing, prosecution and maintenance of patent applications subject to the Emory License. The expense associated with these ongoing patent cost reimbursements to Emory University amounted to $179,958, $98,042, and $89,885 for the years ended December 31, 2014, 2013 and 2012, respectively; and $94,690 and $135,150 for the nine month periods ended September 30, 2015 and 2014, respectively

26

We may only use the Emory Technology for therapeutic or prophylactic HIV or smallpox vaccines. Emory University also reserved the right to use the Emory Technology for research, educational and non-commercial clinical purposes. Due to the use of federal funds in the development of the Emory Technology, the U.S. Government has the irrevocable, royalty-free, paid-up right to practice and have practiced certain patents throughout the world, should it choose to exercise such rights.

We are not a party to any litigation, opposition, interference, or other potentially adverse proceeding with regard to our patent positions. However, if we become involved in litigation, interference proceedings, oppositions or other intellectual property proceedings, for example as a result of an alleged infringement or a third-party alleging an earlier date of invention, we may have to spend significant amounts of money and time and, in the event of an adverse ruling, we could be subject to liability for damages, invalidation of our intellectual property and injunctive relief that could prevent us from using technologies or developing products, any of which could have a significant adverse effect on our business, financial conditions or results of operations. In addition, any claims relating to the infringement of third-party proprietary rights, or earlier date of invention, even if not meritorious, could result in costly litigation, lengthy governmental proceedings, divert management’s attention and resources and require us to enter royalty or license agreements which are not advantageous if available at all.

In addition to patent protection, we also attempt to protect our proprietary products, processes and other information by relying on trade secrets and non-disclosure agreements with our employees, consultants and certain other persons who have access to such products, processes and information. Under these agreements, all inventions conceived by employees are our exclusive property. Nevertheless, there can be no assurance that these agreements will afford significant protection against misappropriation or unauthorized disclosure of our trade secrets and confidential information.

We cannot be certain that any of the current pending patent applications we have licensed, or any new patent applications we may file or license, will ever be issued in the United States or any other country. Even if issued, there can be no assurance that those patents will be sufficiently broad to prevent others from using our products or processes. Furthermore, our patents, as well as those we have licensed or may license in the future, may be held invalid or unenforceable by a court, or third parties could obtain patents that we would need to either license or to design around, which we may be unable to do. Current and future competitors may have licensed or filed patent applications or received patents, and may acquire additional patents or proprietary rights relating to products or processes competitive to ours. In addition, any claims relating to the infringement of third-party proprietary rights, or earlier date of invention, even if not meritorious, could result in costly litigation, lengthy governmental proceedings, divert management’s attention and resources and require us to enter royalty or license agreements which are not advantageous to us, if available at all.

Research and Development

Our expenditures for research and development activities were $1,812,969, $2,914,878, and $3,043,522 during the years ended December 31, 2014, 2013 and 2012, respectively; and $1,166,803 and $1,344,560 for the nine month periods ended September 30, 2015 and 2014, respectively. As our vaccines continue to go through the process to obtain regulatory approval, we expect our research and development costs to continue to increase as human clinical trials proceed. We have not yet formulated any plans for marketing and sales of any vaccine candidate we may successfully develop. Compliance with environmental protection laws and regulations has not had a material effect on our capital expenditures, earnings or competitive position to date.

Properties and Employees

We lease approximately 8,400 square feet of office and laboratory space located at 1900 Lake Park Drive, Suite 380, Smyrna, Georgia under a lease agreement which began November 1, 2009, with an original expiration date of December 31, 2014. We have renewed the lease through December 31, 2016, with a 12-month renewal option. We believe this space is adequate for our current needs. As of December 8, 2015, we had six full-time and three part-time employees. None of our employees are covered by collective bargaining agreements and we believe that our employee relations are good.

27

C orporate Background

Our primary business is conducted by our subsidiary, GeoVax, Inc., which was incorporated under the laws of Georgia in June 2001. The predecessor of our parent company, GeoVax Labs, Inc. (the reporting entity) was originally incorporated in June 1988 under the laws of Illinois as Dauphin Technology, Inc. (“Dauphin”). In September 2006, Dauphin completed a merger with GeoVax, Inc. As a result of the merger, GeoVax, Inc. became a wholly-owned subsidiary of Dauphin, and Dauphin changed its name to GeoVax Labs, Inc. In June 2008, the Company was reincorporated under the laws of Delaware. We currently do not conduct any business other than GeoVax, Inc.’s business of developing new products for the treatment or prevention of human diseases. Our principal offices are located in Smyrna, Georgia (metropolitan Atlanta).

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with “Selected Financial Data” and our consolidated financial statements and the related notes, beginning on page F-1 of this prospectus. This discussion contains forward-looking statements that involve risks and uncertainties because they are based on current expectations and relate to future events and our future financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many important factors, including those set forth under “Risk Factors” and elsewhere in this prospectus.

Overview

GeoVax is a clinical-stage biotechnology company developing human vaccines using our novel platform technology. Our current development programs are focused on Ebola and Marburg viruses, and HIV. Our HIV vaccine technology was developed in collaboration with researchers at Emory University, the NIH, and the CDC, and is exclusively licensed to us from Emory University. We also have nonexclusive licenses to certain patents owned by the NIH. Our Ebola and Marburg vaccines are being developed with technology licensed to us from the NIH.

Our most advanced HIV vaccine development efforts are focused on a preventive vaccine to address the clade B subtype of the HIV virus that is most prevalent in the developed world (primarily North America and Western Europe). All of the clinical trials for our preventive HIV vaccine (through Phase 2a) have been conducted by the HIV Vaccine Trials Network (HVTN) with funding from the NIH. Through a continued collaboration with the NIH and HVTN, in early 2016 we expect to initiate a Phase 1 clinical trial investigating the effect of a “protein boost” to increase the antibody responses elicited by our vaccine. While this effort continues, we are also exploring our options to secure funding to advance our vaccine (without the additional protein boost) directly into pivotal Phase 2b efficacy trials. We have also begun preclinical studies to develop an HIV vaccine candidate for the clade C subtype of HIV prevalent in the developing world (primarily sub-Saharan Africa and India); these studies are currently being supported by NIH grants. Our Ebola vaccine development efforts were initiated in 2014 and we are currently conducting preclinical animal studies through a collaboration with the NIH.

We have neither received regulatory approval for any of our vaccine candidates, nor do we have any commercialization capabilities; therefore, it is possible that we may never successfully derive significant product revenues from any of our existing or future development programs or product candidates.

We expect for the foreseeable future our operations will result in a net loss on a quarterly and annual basis. As of September 30, 2015, we had an accumulated deficit of $31.8 million.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates and adjusts the estimates as necessary. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

Our significant accounting policies are summarized in Note 2 to our consolidated financial statements for the year ended December 31, 2014. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:

We recognize revenue in accordance with the SEC’s Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, as amended by Staff Accounting Bulletin No. 104, Revenue Recognition, (“SAB 104”). SAB 104 provides guidance in applying U.S. generally accepted accounting principles (“GAAP”) to revenue recognition issues, and specifically addresses revenue recognition for upfront, nonrefundable fees received in connection with research collaboration agreements. During the years ended 2014, 2013 and 2012, and the nine months ended September 30, 2015, our revenue consisted of grant funding received from the NIH. Revenue from these arrangements is approximately equal to the costs incurred and is recorded as income as the related costs are incurred.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which creates a new Topic, Accounting Standards Codification Topic 606. The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for the Company beginning in 2017 and allows for either full retrospective adoption or modified retrospective adoption. We are currently evaluating the impact of the adoption of ASU 2014-09 on our financial statements.

Stock-Based Compensation

We account for stock-based transactions in which the Company receives services from employees, directors or others in exchange for equity instruments based on the fair value of the award at the grant date. Compensation cost for awards of common stock is estimated based on the price of the underlying common stock on the date of issuance. Compensation cost for stock options or warrants is estimated at the grant date based on each instrument’s fair value as calculated by the Black-Scholes option pricing model. We recognize stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period for the award.

Liquidity and Capital Resources

At September 30, 2015, we had cash and cash equivalents of $1,821,037 and total assets of $1,998,165, as compared to $1,101,651 and $1,333,198, respectively, at December 31, 2014, and $2,513,861 and $2,839,576, respectively, at December 31, 2013. Working capital totaled $1,778,092 at September 30, 2015, as compared to $1,038,472 at December 31, 2014 and $2,385,990 at December 31, 2013.

Sources and Uses of Cash

Historically, our primary uses of cash have been to finance our research and development activities. We have funded our activities to date primarily from government grants and clinical trial assistance, and from sales of our equity securities. Due to our significant research and development expenditures, we have not been profitable and have generated operating losses since our inception in 2001.

We believe that our existing cash resources will be sufficient to fund our planned operations through the first quarter of 2016. We will require additional funds to continue our planned operations beyond that date. We are currently seeking sources of non-dilutive capital through government grant programs and clinical trial support, and we may also conduct additional offerings of our equity securities. However, additional funding may not be available on favorable terms or at all and if we fail to obtain additional capital when needed, we may be required to delay, scale back, or eliminate some or all of our research and development programs as well as reduce our general and administrative expenses.

Cash Flows from Operating Activities

Net cash used in operating activities was $1,944,573 and $1,616,167 for the nine-month periods ended September 30, 2015 and 2014, respectively. Net cash used in operating activities was $2,250,107, $1,694,592, and $2,441,247 for the years ended December 31, 2014, 2013 and 2012, respectively. Generally, the differences between periods are due to fluctuations in our net losses, offset by non-cash charges such as depreciation and stock-based compensation expense, and by net changes in our assets and liabilities. Our net losses generally fluctuate based on expenditures for our research activities, offset by government grant revenues. As we expand our product development pipeline and move into the later stages of development, we anticipate that our cash expenditures and net losses will increase.

The NIH has funded the costs of conducting all of our human clinical trials (Phase 1 and Phase 2a) to date for our preventive HIV vaccines, with GeoVax incurring certain costs associated with manufacturing the clinical vaccine supplies and other study support. We also expect the NIH to fully fund the cost of another Phase 1 trial (HVTN 114) of our preventive HIV vaccine to begin in early 2016, which will investigate the effect of adding a “protein boost” component to our vaccine. While efforts are underway to evaluate the protein boost concept, we also intend to seek funding to expedite our vaccine (without the additional protein boost) directly into pivotal Phase 2b efficacy trials.

During 2014, we completed a Phase 1 clinical trial (GV-TH-01) investigating the therapeutic use of our GOVX-B11 vaccine in HIV-infected patients. Future therapeutic studies of our vaccine may investigate the vaccine’s ability to act as a “shock agent” in a shock and kill therapy in combination with standard of care antiretroviral drug therapy to seek a cure for HIV infection. We are currently not contemplating the use of any of our existing cash resources for this program. The timetable and specific plans for additional clinical studies will be dependent upon our ability to secure external funding for the program, and on the nature of any potential collaborations we may establish.

Our Ebola/Marburg vaccine program began in late 2014, and our primary activities during 2015 are focused on constructing the vaccines and conducting preclinical animal studies. During April 2015, we entered into a Research Collaboration Agreement with the National Institute of Allergy and Infectious Disease (NIAID), part of NIH, pursuant to which NIAID is contributing certain materials and carrying out animal protection studies in small animals. The initial animal studies are ongoing, and we our goal is to begin human clinical trials in early 2017.

In addition to clinical trial support from the NIH for our preventive HIV vaccines and collaborative research support from NIAID for our Ebola vaccine program, our operations have been partially funded by NIH research grants for our HIV program. As of September 30, 2015, there was $260,522 of unused grant funds available for use during the remainder of 2015 and the first half of 2016. We intend to pursue additional grants from the federal government for our HIV and Ebola programs but cannot be assured of success.

Cash Flows from Investing Activities

Our investing activities have consisted predominantly of capital expenditures. Capital expenditures were $15,850 and $35,503 for the nine month periods ended September 30, 2015 and 2014, respectively. Capital expenditures for the years ended December 31, 2014, 2013 and 2012, were $35,503, $86,603, and $-0-, respectively.

Cash Flows from Financing Activities

Net cash provided by financing activities was $2,679,809 and $-0- for the nine month periods ended September 30, 2015 and 2014, respectively. Net cash provided by financing activities was $873,400, $3,259,131, and $2,309,192 for the years ended December 31, 2014, 2013 and 2012, respectively.

During January 2012, we received $310,160 from stock sales to individual accredited investors (including $36,800 received in payment of a stock subscription receivable from December 2011).

In March 2012, we sold 2,200 shares of our Series A Convertible Preferred Stock, as well as accompanying warrants to purchase 8,799,999 shares of common stock, to a group of institutional investors for an aggregate purchase price of $2.2 million. Net proceeds to the Company, after deduction of placement agent fees and other expenses, were approximately $2.0 million. The cash generated by our financing activities during 2012 also includes $310,160 received in January 2012 related to the sale of our common stock to individual accredited investors in a private placement offering which was initiated during December 2011.

In January 2013, we reduced the exercise price of 2,933,333 of certain stock purchase warrants from $0.75 to $0.60 per share. In consideration for the reduction of the exercise price, the holders of the warrants immediately exercised 1,766,667 of the warrants for cash, resulting in total proceeds to the Company of $1,060,000. We also extended the expiration date of the 1,166,666 unexercised warrants from March 21, 2013 to May 21, 2013. In May 2013, we reduced the exercise price of the 1,166,666 remaining warrants from $0.60 to $0.50 per share. In consideration for the reduction of the exercise price, the holders of the warrants immediately exercised all of the remaining warrants for cash, resulting in total proceeds to the Company of $583,333.

In December 2013, we sold 1,650 shares of our Series B Convertible Preferred Stock to a group of institutional investors for an aggregate purchase price of $1.65 million. Net proceeds to the Company, after deduction of transaction expenses, were approximately $1.6 million. No warrants were issued in connection with the transaction.

31

In October 2014, we entered into an agreement with certain warrant holders to purchase shares of our common stock with respect to the payment to them of a warrant exercise fee of $0.075 per share for each share purchased upon exercise of warrants held by them. In exchange for the fee, they immediately exercised warrants for an aggregate of 3,176,000 shares of our common stock, resulting in proceeds to us of $873,400 (net of the exercise fee).

In February 2015, we sold shares of Series C convertible preferred stock to certain institutional investors for an aggregate purchase price of $3.0 million, and five-year Series D warrants to purchase an aggregate of 16,666,666 shares of our common stock with a current exercise price of $0.11299 per share. Net proceeds to the Company, after deduction of placement agent fees and other expenses, were approximately $2.7 million. The preferred stock is convertible at any time into shares of our common stock at $0.09416 per share, subject to adjustment as provided in the certificate of designation. We also granted to the investors an additional purchase right, evidenced in the form of one-year Series E warrants to purchase up to 16,666,666 of our common stock with a current exercise price of $0.09416 per share, and five-year Series F warrants to purchase up to 16,666,666 shares of our common stock with a current exercise price of $0.11299 per share. The Series E warrants are immediately exercisable. The Series F warrants only become exercisable at the time, and to the extent, that the Series E warrants are exercised.

Our capital requirements, particularly as they relate to our research and development activities, have been and will continue to be significant. We anticipate incurring additional losses for several years as we expand our clinical programs and proceed into higher cost human clinical trials. Conducting clinical trials for our vaccine candidates in development is a lengthy, time-consuming and expensive process. We will not generate revenues from the sale of our technology or products for at least several years, if at all. For the foreseeable future, we will be dependent on obtaining financing from third parties in order to maintain our operations, including our clinical program. Such capital may not be available on terms acceptable to the Company or at all. If we fail to obtain additional funding when needed, we would be forced to scale back or terminate our operations, or to seek to merge with or to be acquired by another company.

We expect that our current working capital (including the net proceeds from the February 2015 financing event discussed above) combined with the remaining available funds from the NIH grants will be sufficient to support our planned level of operations through the first quarter of 2016. We will require additional funds to continue our planned operations beyond that date. We are currently seeking sources of non-dilutive capital through government grant programs and clinical trial support, and we may also conduct additional offerings of our equity securities, although there can be no assurance that we will be able to do so. While we believe that we will be successful in obtaining the necessary financing to fund our operations through government grants and clinical trial support, exercise of stock purchase warrants, or other sources, there can be no assurances that such additional funding will be available to us on reasonable terms or at all. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could have a material adverse effect on our business, operating results, financial condition and prospects.

We have no off-balance sheet arrangements that are likely or reasonably likely to have a material effect on our financial condition or results of operations.

Contractual Obligations

Contractual obligations represent future cash commitments and liabilities under agreements with third parties, and exclude contingent liabilities for which we cannot reasonably predict future payment. Additionally, the expected timing of payment of the obligations presented below is estimated based on current information. Timing of payments and actual amounts paid may be different depending on the timing of receipt of goods or services or changes to agreed-upon terms or amounts for some obligations.

32

As of September 30, 2015, we had noncancellable lease obligations and other firm purchase obligations totaling approximately $222,000, as compared to approximately $297,000 at December 31, 2014. We have no committed lines of credit and no other committed funding or long-term debt. We have employment agreements with our senior management team, each of which may be terminated with 30 days advance notice. The following table represents our contractual obligations as of December 31, 2014, aggregated by type (in thousands):

|  | Payments Due by Period |
Contractual Obligations |  | Total |  |  | Less than 1 Year |  |  | 1-3 Years |  |  | 4-5 Years |  |  | More than 5 years |
Operating Lease Obligations (1) |  | $ | 146 |  |  | $ | 146 |  |  | $ | -- |  |  | $ | -- |  |  | $ | -- |
Firm Purchase Commitments (2) |  |  | 151 |  |  |  | 151 |  |  |  | -- |  |  |  | -- |  |  |  | -- |
Emory University – License Agreement (3) |  |  | -- |  |  |  | -- |  |  |  | -- |  |  |  | -- |  |  |  | -- |
Total |  | $ | 297 |  |  | $ | 297 |  |  | $ | -- |  |  | $ | -- |  |  | $ | -- |

| (1) | Our operating lease obligations relate to the facility lease for our 8,430 square foot facility in Smyrna, Georgia, which houses our laboratory operations and our administrative offices. The lease (as amended), expires on December 31, 2016, with a 12-month renewal option.

| (2) | Firm purchase commitments relate to contracts for research activities related to NIH grants.

| (3) | Pursuant to the Emory License, we have committed to make potential future milestone and royalty payments which are contingent upon the occurrence of future events. Such events include development milestones, regulatory approvals and product sales. Because the achievement of these milestones is currently neither probable nor reasonably estimable, the contingent payments have not been included in the table above or recorded on our Consolidated Balance Sheets. The aggregate total of all potential milestone payments included in the Emory License (excluding royalties on net sales) is approximately $3.5 million.

Net Operating Loss Carryforwards

At December 31, 2014, we had consolidated net operating loss carryforwards for income tax purposes of $64.6 million, which will expire in 2019 through 2034 if not utilized. Approximately $42.6 million of our net operating loss carryforwards relate to the operations of our predecessor, Dauphin Technology, Inc. prior to the 2006 merger between Dauphin Technology, Inc. and GeoVax, Inc. We also have research and development tax credits of approximately $826,000 available to reduce income taxes, if any, which will expire in 2022 through 2034 if not utilized. The amount of net operating loss carryforwards and research tax credits available to reduce income taxes in any particular year may be limited in certain circumstances. Based on an assessment of all available evidence including, but not limited to, our limited operating history in our core business and lack of profitability, uncertainties of the commercial viability of our technology, the impact of government regulation and healthcare reform initiatives, and other risks normally associated with biotechnology companies, we have concluded that it is more likely than not that these net operating loss carryforwards and credits will not be realized and, as a result, a 100% deferred tax valuation allowance has been recorded against these assets.

Results of Operations – Nine Months Ended September 30, 2015 Compared to Nine Months Ended September 30, 2014

Net Loss

We recorded a net loss of $619,899 for the three-month period ended September 30, 2015, as compared to $514,515 for the three-month period ended September 30, 2014. For the nine-month period ended September 30, 2015, we recorded a net loss of $1,996,556, as compared to a net loss of $1,809,970 for nine-month period ended September 30, 2014. Our net losses will typically fluctuate due to the timing of activities and related costs associated with our vaccine research and development activities and our general and administrative costs, as described in more detail below.

Grant Revenue

During the three-month and nine-month periods ended September 30, 2015, we recorded grant revenue of $93,130 and $268,028, respectively, as compared to $322,086 and $659,867, respectively, during the comparable periods of 2014. Grant revenues for these periods relate to grants from the NIH in support of our HIV vaccine development activities. We record revenue associated with these grants as the related costs and expenses are incurred. The difference in our grant revenues from period to period is directly related to our expenditures for activities supported by the grants, and can fluctuate significantly based on the timing of the related expenditures.

33

In September 2007, the NIH awarded us a grant entitled “GM-CSF-Adjuvanted Clade C DNA/MVA and MVA/MVA Vaccines”. The aggregate award (including subsequent amendments) totaled approximately $20.4 million. For this grant, we recorded revenues of $-0- and $75,464 for the three-month and nine-month periods ended September 30, 2015, respectively, as compared to $269,334 and $484,988, respectively during the comparable periods of 2014. There are no unrecognized grant funds remaining and available for use pursuant to this grant as of September 30, 2015.

In July 2013, the NIH awarded us a Small Business Innovative Research (SBIR) grant entitled “Enhancing Protective Antibody Responses for a GM-CSF Adjuvanted HIV Vaccine.” The initial grant award was $276,690 for the first year of a two year project period beginning August 1, 2013. In July 2014, the NIH awarded us $289,641 for the second year of the project period. For this grant, we recorded revenues of $54,067 and $153,501 for the three-month and nine-month periods ended September 30, 2015, respectively, as compared to $52,752 and $174,879, respectively during the comparable periods of 2014. There are no unrecognized grant funds remaining and available for use pursuant to this grant as of September 30, 2015.

In June 2015, the NIH awarded us a Small Business Innovative Research (SBIR) grant entitled “Directed Lineage Immunizations for Eliciting Broadly Neutralizing Antibody.” The initial grant award of $299,585 is for the first year of a two year project period beginning July 1, 2015. For this grant, we recorded revenues of $39,063 for the three-month and nine-month periods ended September 30, 2015; no revenues related to this grant were recorded during the comparable periods of 2014. There is $260,522 in approved grant funds remaining and available for use as of September 30, 2015, which we anticipate recognizing as revenue during the remainder of 2015 and through June 30, 2016.

Research and Development

During the three-month and nine-month periods ended September 30, 2015, we recorded $378,521 and $1,166,803, respectively, of research and development expense as compared to $425,498 and $1,344,560, respectively, during the three-month and nine-month periods ended September 30, 2014. Research and development expense for the three-month and nine-month periods of 2015 includes stock-based compensation expense of $5,340 and $15,972, respectively, while the comparable periods of 2014 include stock-based compensation expense of $7,404 and $24,420, respectively (see discussion under “Stock-Based Compensation Expense” below). Our research and development expenses can fluctuate considerably on a period-to-period basis, depending on our need for vaccine manufacturing by third parties, the timing of expenditures related to our grants from the NIH, the timing of costs associated with clinical trials being funding directly by us, and other factors.

We cannot predict the level of support we may receive from the HVTN, NIH, or other federal agencies (or divisions thereof) for our future research and development efforts. We expect that our research and development costs will increase in the future as we progress into the later stage human clinical trials for our HIV vaccines and as we expand our Ebola and Marburg vaccine development program.

Our vaccine candidates still require significant, time-consuming and costly research and development, testing and regulatory clearances. Completion of clinical development will take several years or more, but the length of time generally varies substantially according to the type, complexity, novelty and intended use of a product candidate. The NIH has funded the costs of conducting all of our human clinical trials to date for our preventive HIV vaccine, with GeoVax incurring costs associated with manufacturing the clinical vaccine supplies and other study support. We are having discussions with the HVTN and NIH with regard to the conduct of an additional trial of our preventive vaccine, and we expect the NIH will provide support for this trial as well. We intend to seek government and/or third party support for future clinical human trials and for production of our vaccine product for use in clinical trials, but there can be no assurance that we will be successful.

The duration and the cost of future clinical trials may vary significantly over the life of the project as a result of differences arising during development of the human clinical trial protocols, including, among others:

| ● | the number of patients that ultimately participate in the clinical trial;

| ● | the duration of patient follow-up that seems appropriate in view of the results;

| ● | the number of clinical sites included in the clinical trials; and

| ● | the length of time required to enroll suitable patient subjects.

Due to the uncertainty regarding the timing and regulatory approval of clinical trials and pre-clinical studies, our future expenditures are likely to be highly volatile in future periods depending on the outcomes of the trials and studies. From time to time, we will make determinations as to how much funding to direct to these programs in response to their scientific, clinical and regulatory success, anticipated market opportunity and the availability of capital to fund our programs.

34

In developing our product candidates, we are subject to a number of risks that are inherent in the development of products based on innovative technologies. For example, it is possible that our vaccines may be ineffective or toxic, or will otherwise fail to receive the necessary regulatory clearances, causing us to delay, extend or terminate our product development efforts. Any failure by us to obtain, or any delay in obtaining, regulatory approvals could cause our research and development expenditures to increase which, in turn, could have a material adverse effect on our results of operations and cash flows. Because of the uncertainties of clinical trials, estimating the completion dates or cost to complete our research and development programs is highly speculative and subjective. As a result of these factors, we are unable to accurately estimate the nature, timing and future costs necessary to complete the development of our product candidates. In addition, we are unable to reasonably estimate the period when material net cash inflows could commence from the sale, licensing or commercialization of such product candidates, if ever.

General and Administrative Expense

During the three-month and nine-month periods ended September 30, 2015, we incurred general and administrative costs of $335,932 and $1,102,262, respectively, as compared to $411,814 and $1,128,478, respectively, during the comparable periods in 2014. General and administrative costs include officers’ salaries, legal and accounting costs, patent costs, amortization expense associated with intangible assets, and other general corporate expenses. General and administrative expense for the three-month and nine-month periods of 2015 include stock-based compensation expense of $11,586 and $34,544, respectively; while the comparable periods of 2014 include stock-based compensation expense of $106,880 and $141,218, respectively (see discussion under “Stock-Based Compensation Expense” below). We expect that our general and administrative costs may increase in the future in support of expanded research and development activities and other general corporate activities.

Stock-Based Compensation Expense

We recorded stock-based compensation expense of $16,926 and $50,516 during the three-month and nine-month periods ended September 30, 2015, respectively, as compared to $114,284 and $165,638, respectively, during the comparable periods of 2014. The expense for the 2014 periods includes $49,750 related to common stock issued for services and $39,711 related to the repricing and extension of certain stock purchase warrants. We allocate stock-based compensation expense to research and development expense or general and administrative expense according to the classification of cash compensation paid to the employee, consultant or director to whom the stock compensation was granted. For the three-month and nine-month periods ended September 30, 2015 and 2014, stock-based compensation expense was allocated as follows:

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
Expense Allocated to: |  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |
General and Administrative Expense |  | $ | 11,586 |  |  | $ | 106,880 |  |  | $ | 34,544 |  |  | $ | 141,218 |
Research and Development Expense |  |  | 5,340 |  |  |  | 7,404 |  |  |  | 15,972 |  |  |  | 24,420 |
Total Stock-Based Compensation Expense |  | $ | 16,926 |  |  | $ | 114,284 |  |  | $ | 50,516 |  |  | $ | 165,638 |

Other Income

Interest income for the three-month and nine-month periods ended September 30, 2015 was $1,424 and $4,481, respectively, as compared to $711 and $3,201, respectively, for comparable periods of 2014. The variances between periods are primarily attributable to cash available for investment and interest rate fluctuations.

Impact of Inflation

For the three-month and nine-month period ended September 30, 2015, we do not believe that inflation and changing prices had a material impact on our operations or on our financial results.

Results of Operations – Years Ended December 31, 2014, 2013 and 2012

Net Loss

We recorded net losses of $2,733,555, $2,284,943, and $2,135,140 for the years ended December 31, 2014, 2013 and 2012, respectively. Our operating results typically fluctuate due to the timing of activities and related costs associated with our vaccine research and development activities and our general and administrative costs, as described in more detail below.

35

Grant Revenue

We recorded grant revenues of $882,956, $2,417,550, and $2,657,327 for the years ended December 31, 2014, 2013 and 2012, respectively. Grant revenues relate to grants from the NIH in support of our HIV vaccine development activities. We record revenue associated with these grants as the related costs and expenses are incurred. The difference in our grant revenues from period to period is directly related to our expenditures for activities supported by the grants, and can fluctuate significantly based on the timing of the related expenditures. There is an aggregate of approximately $229,000 in approved grant funds remaining and available for use as of December 31, 2014. Additional detail concerning our grant revenues is discussed below.

In September 2007, the NIH awarded us a grant entitled “GM-CSF-Adjuvanted Clade C DNA/MVA and MVA/MVA Vaccines”. The aggregate award (including subsequent amendments) totaled approximately $20.4 million. We recorded grant revenues of $624,689, $833,390, and $2,227,924 for the years ended December 31, 2014, 2013 and 2012, respectively, related to this grant, and there was $75,464 of unrecognized grant funds remaining and available for use pursuant to this grant as of December 31, 2014.

In September 2012, the NIH awarded us a grant entitled “Immunogens and Manufacturing” to support our HIV/AIDS vaccine development program. The grant award was for approximately $1.9 million. We recorded grant revenues of $-0-, $1,429,597, and $429,403 for the years ended December 31, 2014, 2013 and 2012, respectively, related to this grant, and all funding pursuant to this grant had been utilized as of December 31, 2014.

In July 2013, the NIH awarded us a Small Business Innovative Research (SBIR) grant entitled “Enhancing Protective Antibody Responses for a GM-CSF Adjuvanted HIV Vaccine.” The initial grant award was approximately $277,000 for the first year of a two year project period beginning August 1, 2013. In July 2014, the NIH awarded us approximately $290,000 for the second year of the project period. We recorded grant revenues of $258,267, $154,563, and $-0- for the years ended December 31, 2014, 2013 and 2012, respectively, related to this grant, and there was $153,501 of unrecognized grant funds remaining and available for use pursuant to this grant as of December 31, 2014.

Research and Development

Our research and development expenses were $1,812,969, $2,914,878, and $3,043,522 for the years ended December 31, 2014, 2013 and 2012, respectively. Research and development expense for these periods includes stock-based compensation expense of $32,134, $41,539, and $78,140 for 2014, 2013 and 2012, respectively (see discussion under “Stock-Based Compensation Expense” below). Since our inception, all of our research and development efforts have been focused on development of human vaccines – initially with a focus on HIV/AIDS vaccines, and with a recent expansion to vaccines for Ebola and Marburg. Our research activities conducted pursuant to our NIH grants are also focused solely on the development of human vaccines.

Our research and development expenses can fluctuate considerably on a period-to-period basis, depending on our need for vaccine manufacturing by third parties, the timing of expenditures related to our grants from the NIH, the timing of costs associated with clinical trials being funding directly by us, and other factors. The overall decrease in research and development expense from 2013 to 2014 can mostly be attributed to lower expenditures related to the activities supported by our grants from the NIH, and lower expenditures associated with a Phase 1 trial of our therapeutic HIV vaccine, which was completed during the first quarter of 2014. We have not received any government support for clinical trials of our therapeutic vaccine. Our research and development costs do not include costs incurred by the HVTN in conducting clinical trials of our preventive HIV vaccines; those costs are funded directly to the HVTN by the NIH.

General and Administrative Expense

Our general and administrative expenses were $1,807,605, $1,792,160, and $1,752,765 for the years ended December 31, 2014, 2013 and 2012, respectively. General and administrative costs include officers’ salaries, legal and accounting costs, patent costs, amortization expense associated with intangible assets, and other general corporate expenses. General and administrative expense includes stock-based compensation expense of $446,969, $360,565, and $231,936 for 2014, 2013 and 2012, respectively (see discussion under “Stock-Based Compensation Expense” below). We expect that our general and administrative costs may increase in the future in support of expanded research and development activities and other general corporate activities.

Stock-Based Compensation Expense

We recorded total stock-based compensation expense of $479,103, $402,104, and $310,076 during the years ended December 31, 2014, 2013 and 2012, respectively, which was allocated to research and development expense or general and administrative expense according to the classification of cash compensation paid to the employee, consultant or director to whom the stock compensation was granted. In addition to amounts related to the issuance of stock options to employees, the figures include amounts related to common stock and stock purchase warrants issued to consultants and non-employee directors. For the three years ended December 31, 2014, stock-based compensation expense was allocated as follows:

|  | 2014 |  |  | 2013 |  |  | 2012 |
General and administrative expense |  | $ | 446,969 |  |  | $ | 360,565 |  |  | $ | 231,936 |
Research and development expense |  |  | 32,134 |  |  |  | 41,539 |  |  |  | 78,140 |
Total stock option expense |  | $ | 479,103 |  |  | $ | 402,104 |  |  | $ | 310,076 |

Other Income

Interest income was $ 4,063, $4,545, and $3,820 for the years ended December 31, 2014, 2013 and 2012, respectively. The variances between years are primarily attributable to the cash available for investment and to interest rate fluctuations.

Impact of Inflation

For the three-year period ended December 31, 2014, we do not believe that inflation and changing prices had a material impact on our operations or on our financial results.

Off-Balance Sheet Arrangements

We have not entered into off-balance sheet financing arrangements, other than operating leases.

The agreements also provide for the advancement of expenses to these individuals subject to specified conditions.

Potential Payments Upon a Change-in-Control

Our 2006 Equity Incentive Plan contains provisions that could lead to an accelerated vesting of options or other awards. In the event of certain change-in-control transactions described in the Plan, (i) outstanding options or other awards under the Plan may be assumed, converted or replaced; (ii) the successor corporation may substitute equivalent options or other awards or provide substantially similar consideration to Plan participants as were provided to stockholders (after taking into account the existing provisions of the options or other awards); or (iii) the successor corporation may replace options or awards with substantially similar shares or other property.

In the event the successor corporation (if any) refuses to assume or substitute options or other awards as described (i) the vesting of any or all options or awards granted pursuant to the Plan will accelerate upon the change-in-control transaction, and (ii) any or all options granted pursuant to the Plan will become exercisable in full prior to the consummation of the change-in-control transaction at such time and on such conditions as the Compensation Committee determines. If the options are not exercised prior to the consummation of the change-in-control transaction, they shall terminate at such time as determined by the Compensation Committee. Subject to any greater rights granted to Plan participants under the Plan, in the event of the occurrence of a change-in-control transaction any outstanding options or other awards will be treated as provided in the applicable agreement or plan of merger, consolidation, dissolution, liquidation, or sale of assets.

If the Company experienced a change-in-control transaction described in the Plan on December 31, 2014, the value of accelerated options for each Named Executive Officer, based on the difference between the closing price of our common stock on the OTC Market on December 31, 2014, and, if lower, the exercise price per share of each option for which vesting would be accelerated for each Named Executive Officer, would be $0.

Our employment agreements with each Named Executive Officer provide for payment to each Named Executive Officer if we terminate such Named Executive Officer’s employment without cause. If each Named Executive Officer was terminated without cause on December 31, 2014, the following amounts, which represent one week of pay for each full year of service to the Company, would be payable to each Named Executive Officer as salary continuance under the terms of such Named Executive Officer’s employment agreement: Dr. McNally - $19,038; Mr. Reynolds - $32,708; and Dr. Robinson - $28,619.

In October 2013, our Board of Directors approved amendments to the employment agreements with each Named Executive Officer These 2013 amendments include severance provisions in the event of a change in control and a qualifying termination of employment. Specifically, if a Named Executive Officer is terminated at any time during the three month period which immediately precedes a change in control (as defined in the amendment) or during the one year period following a change in control, then the Company would pay an amount in cash equal to (a) a multiple of the Named Executive Officer’s then base salary and target annual bonus (3x for Dr. McNally, 2x for Mr. Reynolds, and 2x for Dr. Robinson), (b) a multiple of the cost to provide 401(k) or other deferred compensation or health and welfare benefits to the Named Executive Officer (3x for Dr. McNally, 2x for Mr. Reynolds, and 2x for Dr. Robinson), and (c) a tax gross-up payment (if an excise tax is imposed by § 4999 of the Internal Revenue Code or any related interest or penalties are incurred by the officer) pursuant to the amendment. The amendments also provide for full and complete vesting of all stock option grants held by the Named Executive Officers.

Outstanding Equity Awards at Fiscal Year-End

GeoVax has awarded stock options to its senior management and other employees. The terms of these awards typically provide for vesting over a defined period of time, generally three years. The options expire if not exercised within ten years from the date of grant. The Company does not have a formula for determining stock option awards. Awards are generally based on the subjective judgment of the President and Chief Executive Officer and on the Compensation Committee’s subjective judgment.

The following table sets forth certain information with respect to unexercised options previously awarded to our Named Executive Officers that were outstanding as of December 31, 2014.

Other Benefits Provided to Executive Officers

Mr. Reynolds and Dr. Robinson are eligible for health insurance and 401(k) benefits at the same level and subject to the same conditions as provided to all other employees. Dr. McNally is eligible for 401(k) benefits at the same level and subject to the same conditions as provided to all other employees, but he is currently ineligible for health insurance due to his time commitment to the Company being less than the required 30 hours per week. GeoVax participates in a multi-employer defined contribution retirement plan (the “401k Plan”) administered by a third party service provider; and the Company contributes to the 401k Plan on behalf of all its eligible employees based upon the same matching formula. The amounts shown in the Summary Compensation Table under the heading “Other Compensation” represent the value of the Company’s matching contributions to the 401(k) accounts of these executive officers. Executive officers did not receive any other perquisites or other personal benefits or property from the Company or any other source.

Director Compensation Plan

In March 2007, the Board of Directors approved a recommendation from the Compensation Committee for director compensation, which we refer to as the “Director Compensation Plan.” It was subsequently amended in March 2008, December 2009, and in December 2010. The Director Compensation Plan applies only to non-employee directors. Directors who are employees of the Company receive no compensation for their service as directors or as members of committees.

Cash Fees

For 2014, each non-employee director received an annual retainer (paid quarterly) of $5,000 for service as a member of the Audit Committee and $3,300 for service as a member of the Compensation Committee or the Nominating and Corporate Governance Committee. The Chairman of the Audit Committee received an annual retainer of $9,000, and the Chairman of each of the Compensation Committee and the Nominating and Corporate Governance Committee received an annual retainer of $6,000. These retainers were also paid quarterly. Non-employee directors also received fees for each Board of Directors or Committee meeting attended as follows: $3,000 for in person Board of Directors meetings ($1,500 for telephonic meetings), $1,000 for in person Committee meeting chaired ($750 for telephonic meetings), and $500 for in person Committee meeting attended as a non-chair member ($400 for telephonic meetings). Mr. Dodd, the non-employee Chairman of the Board during 2013, received an annual retainer of $30,000 (paid quarterly) and was not entitled to additional fees for Board meetings attended, but did receive additional fees for committees on which he serves.

45

Stock Option Grants

Each of our current non-employee directors received a grant of options to purchase 26,400 shares of common stock on the date that such non-employee director was first elected or appointed. We currently do not have a formula for determining annual stock option grants to directors (upon their re-election to the Board of Directors, or otherwise). Such option grants are currently determined by the Board of Directors, upon recommendation by the Compensation Committee based on the Compensation Committee’s annual deliberations and review of the director compensation structure of similar companies. At its meeting in December 2015, upon a recommendation of the Compensation Committee, the Board of Directors approved an annual stock option grant of 30,000 shares to its non-employee members.

Expense Reimbursement

All directors are reimbursed for expenses incurred in connection with attending meetings of the Board of Directors and committees.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Policies and Procedures for Approval of Related Party Transactions

Our Audit Committee is responsible for reviewing and approving all transactions or arrangements between the Company and any of our directors, officers, principal stockholders or any of their respective affiliates, associates or related parties, other than transactions with officers which are covered by the duties of the Compensation Committee. In determining whether to approve or ratify a related party transaction, the Audit Committee will discuss the transaction with management and will consider all relevant facts and circumstances available to it including:

| ● | whether the terms of the transaction are fair to the Company and at least as favorable to the Company as would apply if the transaction did not involve a related party.

| ● | whether there are demonstrable business reasons for the Company to enter into the transaction.

| ● | whether the transaction would impair the independence of a non-employee director; and

| ● | whether the transaction would present an improper conflict of interest for any director or executive officer, taking into account the size of the transaction, the direct or indirect nature of the related party’s interest in the transaction and the ongoing nature of any proposed relationship, and any other factors the Audit Committee deems relevant.

These policies are in writing and included in the Company’s minute book.

Our Board of Directors has made the following findings and adopted the following policies (in writing) regarding related party transactions:

| ● | The Company has not made and will not make loans or loan guarantees on behalf of any director, officer, beneficially owner of more than 5% of our common stock, or other person constituting a Promoter, as such term is defined in the NASAA Statement of Policy Regarding Corporate Securities Definitions.

| ● | The Company has not engaged and will not engage in material transactions with any director, officer, beneficial owner of more than 5% of our common stock, or other person constituting a Promoter, as such term is defined in the NASAA Statement of Policy Regarding Corporate Securities Definitions, except as described below or as otherwise approved by our Audit Committee consistent with the policies and procedures described below.

| ● | The Company will make any future material affiliated transactions on terms that are no less favorable to the Company than those that can be obtained from unaffiliated third parties.

| ● | A majority of the Company’s Audit Committee will approve all future material transactions.

| ● | The Company’s officers, directors, and counsel will:

| o | consider their due diligence and assure that there is a reasonable basis for these representations, and

| o | consider whether to embody the representations in the issuer’s charter or bylaws.

Transactions with Related Parties

Emory University is a significant stockholder of the Company, and our primary product candidates are based on technology rights subject to a license agreement with Emory University, which we refer to as the Emory License. The Emory License, among other contractual obligations, requires payments based on milestone achievements, royalties on sales by the Company or on payments to the Company by our sublicensees, and payment of maintenance fees in the event certain milestones are not met within the time periods specified in the Emory License. We may terminate the Emory License upon 90 days prior written notice. In any event, the Emory License expires on the date of the latest expiration date of the underlying patents. We are also obligated to reimburse Emory University for certain ongoing costs in connection with the filing, prosecution and maintenance of patent applications subject to the Emory License. The expense associated with these ongoing patent reimbursements to Emory University amounted to $179,958 for the year ended December 31, 2014 and $94,690 for the nine months ended September 30, 2015.

On October 14, 2014, we entered into a letter agreement with Sabby Healthcare Master Fund, Ltd. and Sabby Volatility Warrant Master Fund, Ltd. with respect to the payment to them of a warrant exercise fee of $0.075 per share for each share purchased upon exercise of Series A or Series C Common Stock Purchase Warrants (“Warrants”) held by them. Each of these parties at that time held Warrants to acquire an aggregate of 2,666,666 shares of our common stock. They agreed to exercise Warrants equal to 9.98% of the outstanding shares of GeoVax (3,176,000 shares in the aggregate) upon execution of the letter, and we paid the exercise fee of $238,200 subsequent to our receipt of the exercise price. See “Selling Stockholders” for information regarding the Purchasers’ current share ownership.

On February 25, 2015, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with Sabby Healthcare Master Fund, Ltd. and Sabby Volatility Warrant Master Fund, Ltd. (collectively, the “Purchasers”) providing for the issuance and sale to the Purchasers of an aggregate of 3,000 shares of our Series C Convertible Preferred Stock (the “Preferred Shares”) and related warrants for gross proceeds to the Company of $3.0 million. Each Preferred Share was initially convertible into approximately 5,555.55 shares of our Common Stock for an aggregate total of 16,666,666 shares of our Common Stock (the “Conversion Shares”). The terms of the Preferred Shares include anti-dilution provisions. Pursuant to the Certificate of Designation which authorized the Series C Convertible Preferred Stock, the Preferred Shares could initially be converted at any time at the option of the Purchasers into shares of our Common Stock at an initial conversion price of $0.18 per share (the “Conversion Price”). The Certificate of Designation contains price adjustment provisions, which may, under certain circumstances, (i) reduce the Conversion Price on several future dates, including the effective date of the registration statement to be filed to cover resale of the Conversion Shares, according to a formula based on the then-current market price for our common stock. We closed this transaction on February 27, 2015. On April 8, 2015 the Conversion Price was adjusted to $0.142 per share and on December 4, 2015 the Conversion Price was further adjusted to $0.9416 per share, resulting in a current aggregate total of 31,860,662 shares of our common stock (“Conversion Shares”) into which the Series C Preferred Shares currently may be converted.

Pursuant to the Securities Purchase Agreement, each Purchaser was also issued a Series D Warrant, a Series E Warrant and a Series F Warrant (collectively, the “Warrants”), each to purchase up to a number of shares of the Company’s Common Stock equal to 100% of the Conversion Shares underlying the Preferred Shares issued to such Purchaser pursuant to the Securities Purchase Agreement (up to 16,666,666 shares in the aggregate for each of the three series of warrants, or approximately 50,000,000 shares in total) (the “Warrant Shares”). The Series D Warrants had an initial exercise price of $0.22 per share, are exercisable immediately, and have a term of exercise equal to five years from the date of issuance. The Series E Warrants had an initial exercise price of $0.18 per share, are exercisable immediately, and have a term of exercise equal to one year from the date of issuance. The Series F Warrants had an initial exercise price of $0.22 per share and have a term of exercise equal to five years from the date of issuance, but only vest and become exercisable upon, and in proportion to, the exercise of the one-year Series E Warrants held by each Purchaser (or its assigns). The Warrants contain anti-dilution and price adjustment provisions, which may, under certain circumstances, (i) reduce the exercise price on several future dates, including the effective date of the registration statement to be filed to cover resale of the shares subject to the Warrants, according to a formula based on the then-current market price for our common stock and (ii) reduce the exercise price to match if we sell or grant options to purchase, including rights to reprice, our common stock or common stock equivalents at a price lower than the exercise price of the Warrants, or if we announce plans to do so. The number of shares subject to warrants will not increase due to such reductions in exercise price. We also issued the Maxim Warrant to our placement agent to acquire 1,333,333 shares of our common stock with an initial exercise price of $0.22 per share on substantially the same terms and conditions of the Series D warrants. On April 8, 2015 the exercise prices of the Series D and Series F Warrants were reduced to $0.1704 per share and the exercise prices of the Series E Warrants and the Maxim Warrant were reduced to $0.142 per share; and on December 4, 2015 the exercise prices of the Series D, Series F and Maxim Warrants were reduced to $0.11299 per share and the exercise price of the Series E Warrants were reduced to $0.09416 per share. The Purchasers also received a price adjustment on Series A Warrants to purchase 1,207,332 common shares previously issued to them, resulting in a reduction of the exercise price from $0.142 to $0.09416. See “Selling Stockholders” for information regarding the Purchasers’ current share ownership.

47

The Purchasers also have the right to participate in certain future financings, subject to certain exceptions, and may invest up to 75% of the aggregate amount invested at that time. The Preferred Shares do not have voting rights except as required by law and are not entitled to a dividend. When issued, the Conversion Shares will have the voting rights afforded to all shares of Common Stock. The Preferred Shares have a liquidation preference equal to the initial purchase price.

On February 25, 2015, in connection with the closing of the private placement, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Purchasers. Under the Registration Rights Agreement, we are required to file a registration statement within 30 calendar days after signing the Registration Rights Agreement. Our failure to meet the filing deadlines and other requirements set forth in the Registration Rights Agreement may subject us to monetary penalties. Pursuant to the Registration Rights Agreement, we filed a registration statement with the Securities and Exchange Commission (“SEC”) on March 20, 2015. It was declared effective by the SEC on April 8, 2015, which triggered the price adjustment provisions of the Series C Preferred Shares and the related warrants. As of that date, the conversion price of the Series C Preferred Shares was reduced to $0.142, the exercise prices of the Series D Warrants, Series F Warrants and Maxim Warrants were reduced to $0.1704, and the exercise price of the Series E Warrants was reduced to $0.142. On November 27, 2015, in accordance with the terms of the Securities Purchase Agreement, additional price adjustment provisions of the Series C Preferred Shares and the related warrants were triggered. Five days subsequent to that date, on December 4, 2015, the conversion price of the Series C Preferred Shares was reduced to $0.09416, the exercise prices of the Series D Warrants, Series F Warrants and Maxim Warrants were reduced to $0.11299, and the exercise price of the Series E Warrants was reduced to $0.09416.

SELLING STOCKHOLDERS

This prospectus relates to the resale by the selling stockholders named below from time to time of up to a total of 10,733,902 shares that are owned by or issuable to the selling stockholders. The number of shares is subject to adjustment as described at “Description of Securities.” The common stock offered by this prospectus is being offered by the selling stockholders for their own accounts.

Private Placement Transaction

On February 27, 2015, we completed a private placement transaction and issued to a total of 3,000 shares of Series C Preferred Stock, with a stated value of $1,000 per share and an initial conversion price of $0.18, to two accredited investors. On April 8, 2015, pursuant to certain price adjustment provisions contained in the transaction documents, the conversion price was adjusted to $0.142, and further adjusted to $0.09416 on December 4, 2015. Each share of Series C Preferred Stock is currently convertible into 10,620.22 shares of our common stock. Each purchaser of a share of Series C Preferred Stock also acquired a Series D, a Series E, and a Series F Warrant (collectively, the “2015 Warrants”) to purchase a share of our common stock. See “Description of Securities” for details of the terms of these warrants. We also issued a warrant to Maxim Partners LLC to purchase 1,333,333 shares of our stock on substantially the same terms and conditions as the Series D warrants. The Series C Convertible Preferred Stock and the 2015 warrants were issued in reliance upon exemptions provided by Section 4(2) of the Securities Act for the offer and sale of securities not involving a public offering and Regulation D promulgated thereunder.

Selling Stockholders

The table below, which was prepared based on information supplied to us by the selling stockholders, sets forth information regarding the beneficial ownership of outstanding shares of our common stock owned by the selling stockholders and the shares that they may sell or otherwise dispose of from time to time under this prospectus. Each of the selling stockholders, or their respective transferees, donees or their successors, may resell, from time to time, all, some or none of the shares of our common stock covered by this prospectus, as provided in this prospectus under the section entitled “Plan of Distribution” and in any applicable prospectus supplement. However, we do not know when, in what amount, or at what specific prices the selling stockholders may offer their shares for sale under this prospectus, if any.

The number of shares disclosed in the table below as “beneficially owned” are those beneficially owned as determined under the rules of the SEC. Such information is not necessarily indicative of ownership for any other purpose. Under the rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. In computing the number of shares beneficially owned by a selling stockholder and the percentage of ownership of that selling stockholder, shares of common stock underlying shares of Series C Preferred Stock, options or warrants held by that selling stockholder that are convertible or exercisable, as the case may be, within 60 days of December 8, 2015 are included, subject to the “Maximum Percentage” limitation described in footnote 1 to the table below. Those shares, however, are not deemed outstanding for the purpose of computing the percentage ownership of any other selling stockholder. Each selling stockholder’s percentage of ownership in the following table is based upon 31,950,813 shares of our common stock outstanding as of December 8, 2015. Please note that the column titled “Total Shares that may be Offered and Sold Hereby” includes all shares that may be issued and sold pursuant to this prospectus.

Holders of our common stock are entitled to one vote for each share held in the election of directors and in all other matters to be voted on by the stockholders. There is no cumulative voting in the election of directors. Holders of common stock are entitled to receive dividends as may be declared from time to time by our Board of Directors out of funds legally available therefor, and subject to the rights of holders of our Series B and Series C Preferred Stock. In the event of liquidation, dissolution or winding up of the Company, holders of common stock are to share in all assets remaining after the payment of liabilities, and satisfaction of the liquidation preference of our outstanding Series B and Series C Preferred Stock. Holders of common stock have no pre-emptive or conversion rights and are not subject to further calls or assessments. There are no redemption or sinking fund provisions applicable to the common stock. The rights of the holders of the common stock are subject to any rights that may be fixed for holders of preferred stock, such as the Series B and Series C Preferred Stock. All of the outstanding shares of common stock are fully paid and non-assessable.

Series A Convertible Preferred Stock

We are authorized to issue up to 2,200 shares of our Series A convertible preferred stock, which we refer to as the “Series A Preferred Stock.” No shares of our Series A Preferred Stock, $0.01 par value are outstanding.

Series B Convertible Preferred Stock

We are authorized to issue up to 1,650 shares of our Series B Preferred Stock, which we refer to as the “Series B Preferred Stock.” As of December 11, 2015, 100 shares of our Series B Preferred Stock, $0.01 par value, were outstanding.

The Series B Preferred Stock is convertible at the option of the holder at any time into shares of common stock at a conversion ratio determined by dividing the $1,000 stated value of the Series A convertible preferred stock by a conversion price of $0.35 per share. As of December 8, 2015, an aggregate of 285,714 shares of our common stock are issuable upon conversion of the 100 outstanding shares of Series B Preferred Stock. The conversion price of the Series B Preferred Stock is subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders.

Subject to limited exceptions, a holder of the Series B Preferred Stock will not have the right to convert any portion of its Series B Preferred Stock if the holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of shares of our common stock outstanding immediately after giving effect to its conversion.

50

The holders of Series B Preferred Stock will be entitled to receive any securities or rights to acquire securities or property granted or issued by us pro rata to the holders of our common stock to the same extent as if such holders had converted all of their shares of Series B Preferred Stock. No distribution may be made on the common stock so long as any dividend due on the Series B Preferred Stock remains unpaid. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the holders of Series B Preferred Stock will be entitled to receive, upon conversion of their shares, any securities or other consideration received by the holders of our common stock pursuant to the fundamental transaction.

Except as required by law, holders of the Series B Preferred Stock are not entitled to voting rights; provided, however, that the affirmative vote of the holders of a majority of the outstanding shares of Series B Preferred Stock is required to take certain actions that may alter or change adversely the rights or preferences of the holders of Series B Preferred Stock, increase the number of shares of Series B Preferred Stock, or authorize a new class ranking senior or pari passu to the Series B Preferred Stock. The Series B Preferred Stock has a liquidation preference equal to $1,000 per share.

The securities purchase agreement and related registration rights agreement, as well as the certificate of designation authorizing the Series B Preferred Stock include certain other agreements and covenants for the benefit of the holders of the Series B Preferred Stock, including several restrictions that have now expired, and a requirement to use our best efforts to maintain the listing or trading of our common stock on one or more specified United States securities exchanges or regulated quotation services.

Series C Convertible Preferred Stock

We are authorized to issue up to 3,000 shares of our Series C Convertible Preferred Stock, which we refer to as the “Series C Preferred Stock.” As of December 11, 2015, 3,000 shares of our Series C Preferred Stock, par value $0.01 per share, were outstanding.

The Series C Preferred Stock is convertible at the option of the holder at any time into shares of common stock at a conversion ratio determined by dividing the $1,000 stated value of the Series C Preferred Stock by a current conversion price of $0.09416 per share. As of December 8, 2015, an aggregate of 31,860,662 shares of our common stock are issuable upon conversion of the outstanding shares of Series C Preferred Stock. The conversion price of the Series C Preferred Stock is subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders. The conversion price is also subject to additional price adjustment provisions, which may, under certain circumstances, reduce the conversion price.

Subject to limited exceptions, a holder of the Series C Preferred Stock will not have the right to convert any portion of its Series C Preferred Stock if the holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of our common stock outstanding immediately after giving effect to its conversion. Upon 61 days’ prior notice from a holder, the 4.99% limitation may be increased to 9.99% for that holder and its affiliates.

The holders of Series C Preferred Stock will be entitled to receive any securities or rights to acquire securities or property granted or issued by us pro rata to the holders of our common stock to the same extent as if such holders had converted all of their shares of Series A convertible preferred stock. No distribution may be made on the common stock so long as any dividend due on the Series C Preferred Stock remains unpaid. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the holders of Series C Preferred Stock will be entitled to receive, upon conversion of their shares, any securities or other consideration received by the holders of our common stock pursuant to the fundamental transaction.

Except as required by law, holders of the Series C Preferred Stock are not entitled to voting rights; provided, however, that the affirmative vote of the holders of a majority of the outstanding shares of Series C Preferred Stock is required to take certain actions that may alter or change adversely the rights or preferences of the holders of Series C Preferred Stock, increase the number of shares of Series C Preferred Stock, or authorize a new class ranking senior or pari passu to the Series C Preferred Stock. The Series C Preferred Stock has a liquidation preference equal to $1,000 per share.

The securities purchase agreement and related registration rights agreement, as well as the certificate of designation authorizing the Series C Preferred Stock include certain other agreements and covenants for the benefit of the holders of the Series C Preferred Stock, including a prohibition on our issuing additional debt or equity securities with a variable conversion or exercise price until no Series C Preferred Stock remains outstanding. We also agreed to provide the holders with the right to participate in future financings, up to 75% of the financing amount, for 18 months from February 25, 2015, and undertook to use our best efforts to maintain the listing or trading of our common stock on one or more specified United States securities exchanges or regulated quotation services.

51

Undesignated Preferred Stock

Subject to the restrictions set forth in the certificate of designation for our Series B and Series C Preferred Stock, our Board of Directors has the authority to issue up to 9,996,900 additional shares of preferred stock in one or more series and fix the number of shares constituting any such series, the voting powers, designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, including the dividend rights, dividend rate, terms of redemption (including sinking fund provisions), redemption price or prices, conversion rights and liquidation preferences of the shares constituting any series, without any further vote or action by the stockholders. For example, the Board of Directors is authorized to issue a stockholder of preferred stock that would have the right to vote, separately or with any other stockholder of preferred stock, on any proposed amendment to our certificate of incorporation, or on any other proposed corporate action, including business combinations and other transactions.

We will not offer preferred stock unless the offering is approved by a majority of our independent directors. The independent directors will have access, at our expense, to our counsel or independent counsel.

The Series A, B and C Warrants

Pursuant to the terms of the securities purchase agreement for the sale of the Series A Preferred Stock, each purchaser was also issued a Series A Warrant, a Series B Warrant and a Series C Warrant, each to purchase up to a number of shares of the Company’s common stock equal to 100% of the common stock underlying the preferred shares issued to such purchaser pursuant to the securities purchase agreement (up to 2,933,333 shares in the aggregate for each series of warrants, or 8,799,999 shares in total). The Series A Warrants have a current exercise price of $0.09416 per share, are fully exercisable, and have a term of exercise equal to five years from the date of issuance. There are currently no Series B Warrants outstanding. The Series C Warrants have a current exercise price of $0.11299 per share and have a term of exercise equal to five years from the date of issuance.

The exercise price of the warrants and, in some cases, the number of shares issuable upon exercise, are subject to adjustment in the case of stock splits, stock dividends, combinations of shares, similar recapitalization transactions and certain pro-rata distributions to common stockholders. The exercise price, but not the number of shares of common stock issuable upon exercise, will also be adjusted to match the lower price if we sell or grant (or announce a sale or grant) of any shares of common stock or securities convertible into, or rights to acquire, common stock at an effective price per share that is lower than the then exercise price, except in the event of certain exempt issuances. In addition, upon exercise of the warrants the warrant holders will be entitled to receive any securities or rights to acquire securities or property granted or issued by us pro rata to the holders of our common stock to the same extent as if such holders had then exercised the warrants. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the warrant holders will be entitled to receive, upon exercise of their warrants, any securities or other consideration received by the holders of common stock pursuant to the fundamental transaction. Under certain circumstances, after a fundamental transaction, holders may be entitled to receive a cash payment equal to the value of the Series A or C Warrants, computed as provided in those warrants. Any successor to us or surviving entity shall assume the obligations under the warrants.

The warrant holders must surrender payment in cash of the aggregate exercise price of the shares being acquired upon exercise of the warrants. If there is no effective registration statement registering, or no current prospectus available for the resale of the shares issuable upon exercise of the warrants, then the warrants may be exercised on a “net” or “cashless” basis. No fractional shares of common stock will be issued in connection with the exercise of a warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Subject to limited exceptions, a holder of the Series A or C Warrants will not have the right to exercise the warrant if the holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of our common stock outstanding immediately after giving effect to its conversion. Upon 61 days’ prior notice from a holder, the 4.99% limitation may be increased to 9.99% for that holder. The Series A and Series C Warrants held by two investors have been amended to increase the beneficial ownership limitation to 9.99%.

52

The Series D, E and F Warrants

Pursuant to the terms of the securities purchase agreement for the sale of the Series C Preferred Stock, each purchaser was also issued a Series D Warrant, a Series E Warrant and a Series F Warrant, each such warrant representing the right to purchase up to a number of shares of the Company’s Common Stock equal to 100% of the Common Stock underlying the preferred shares issued to such purchaser pursuant to the securities purchase agreement (up to 16,666,666 shares in the aggregate for each series of warrants, or approximately 50,000,000 shares in total). The Series D Warrants have a current exercise price of $0.11299 per share, are exercisable immediately, and have a term of exercise equal to five years from the date of issuance. The Series E Warrants have a current exercise price of $0.09416 per share, are exercisable immediately, and have a term of exercise equal to one year from the date of issuance. The Series F Warrants have a current exercise price of $0.11299 per share and have a term of exercise equal to five years from the date of issuance, but only vest and become exercisable upon, and in proportion to, the exercise of the one-year Series E Warrants held by each Purchaser (or its assigns). The Warrants contain anti-dilution and price adjustment provisions, which may, under certain circumstances, reduce the exercise price on several future dates including a provision which reduces the exercise price to match if we sell or grant options to purchase, including rights to reprice, our common stock or common stock equivalents at a price lower than the exercise price of the Warrants, or if we announce plans to do so. The number of shares subject to warrants will not increase due to such reductions in exercise price. In addition, upon exercise of the warrants the warrant holders will be entitled to receive any securities or rights to acquire securities or property granted or issued by us pro rata to the holders of our common stock to the same extent as if such holders had then exercised the warrants. In the event of a fundamental transaction, such as a merger, consolidation, sale of substantially all assets and similar reorganizations or recapitalizations, the warrant holders will be entitled to receive, upon exercise of their warrants, any securities or other consideration received by the holders of common stock pursuant to the fundamental transaction. Under certain circumstances, after a fundamental transaction, holders may be entitled to receive a cash payment equal to the value of the Series D, E or F Warrants, computed as provided in those warrants. Any successor to us or surviving entity shall assume the obligations under the warrants.

The warrant holders must surrender payment in cash of the aggregate exercise price of the shares being acquired upon exercise of the warrants. If there is no effective registration statement registering, there are insufficient authorized shares of our common stock available, or there is no current prospectus available for the resale of the shares issuable upon exercise of the warrants, then the warrants may be exercised on a “net” or “cashless” basis. No fractional shares of common stock will be issued in connection with the exercise of a warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Subject to limited exceptions, a holder of the Series D, E or F Warrants will not have the right to exercise the warrant if the holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of shares of our common stock outstanding immediately after giving effect to its conversion.

The Maxim Warrant

As noted, the Company also issued the Maxim Warrant to is placement agent in February 2015. The Maxim Warrant grants the right to acquire 1,333,333 shares of our common stock at a current exercise price of $0.11299 per share on substantially the same terms and conditions as the Series D Warrants.

Delaware Anti-Takeover Law

We have elected not to be subject to certain provisions of Delaware law that could make it more difficult to acquire us by means of a tender offer, a proxy contest, open market purchases, removal of incumbent directors and otherwise. These provisions, summarized below, are expected to discourage types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us to first negotiate with our Board of Directors.

In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in various “business combination” transactions with any interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

| • | the transaction is approved by the corporation’s board of directors prior to the date the interested stockholder obtained interested stockholder status;
| • | upon consummation of the transaction that resulted in the stockholder’s becoming an interested stockholder, the stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by (a) persons who are directors and also officers and (b) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
| • | on or subsequent to the date the business combination is approved by the corporation’s board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least 66 2 / 3 % of the outstanding voting stock that is not owned by the interested stockholder.

53

A “business combination” is defined to include mergers, asset sales and other transactions resulting in financial benefit to a stockholder. In general, an “interested stockholder” is a person who, together with affiliates and associates, owns or within three years, did own, 15% or more of a corporation’s voting stock.

Section 203 applies to Delaware corporations that have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders; provided, however, the restrictions of this statute will not apply to a corporation if:

| • | the corporation’s original charter contains a provision expressly electing not to be governed by the statute;
| • | the corporation’s board of directors adopts an amendment to the corporation’s bylaws within 90 days of the effective date of the statute expressly electing not to be governed by it;
| • | the stockholders of the corporation adopt an amendment to its charter or bylaws expressly electing not to be governed by the statute (so long as such amendment is approved by the affirmative vote of a majority of the shares entitled to vote);
| • | a stockholder becomes an interested stockholder inadvertently and as soon as practicable divests himself of ownership of a sufficient number of shares so that he ceases to be an interested stockholder, and during the three year period immediately prior to a business combination, would not have been an interested stockholder but for the inadvertent acquisition;
| • | the business combination is proposed prior to the consummation or abandonment of a merger or consolidation, a sale, lease, exchange, mortgage, pledge, transfer or other disposition of assets of the corporation or a proposed tender or exchange offer for 50% or more of the outstanding voting shares of the corporation; or
| • | the business combination is with an interested stockholder who became an interested stockholder at a time when the restrictions contained in the statutes did not apply.

Our certificate of incorporation includes a provision electing not to be governed by Section 203 of the DCGL. Accordingly, our board of directors does not have the power to reject certain business combinations with interested stockholders based on Section 203 of the DCGL.

Indemnification

Section 145 of the Delaware General Corporation Law, or DGCL, provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to an action, suit or proceeding (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the corporation’s request in such a capacity for another entity against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit or proceeding. The power to indemnify applies (i) if such person is successful on the merits or otherwise in defense of any action, suit or proceeding or (ii) if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The power to indemnify applies to actions brought by or in the right of the corporation as well, but only to the extent of defense expenses (including attorneys’ fees but excluding amounts paid in settlement), actually and reasonably incurred and not to any satisfaction of judgment or settlement of the claim itself, and with the further limitation that in such actions no indemnification shall be made in the event of any adjudication of negligence or misconduct in the performance of his duties to the corporation, unless a court believes that in light of all the circumstances indemnification should apply.

Our bylaws provide that we may indemnify any person 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 (other than an action by or in the right of the Company) by reason of the fact that the person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. Our bylaws also provide that we may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Company to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Company unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

54

Under our bylaws, expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Company 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 such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Company. Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents may be so paid upon such terms and conditions, if any, as we deem appropriate.

The indemnification and advancement of expenses provided by our bylaws is not exclusive, both as to action in such person’s official capacity and as to action in another capacity while holding such office.

Our bylaws also provide that we may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Company would have the power to indemnify such person against such liability under our bylaws. The Company maintains an insurance policy providing for indemnification of its officers, directors and certain other persons against liabilities and expenses incurred by any of them in certain stated proceedings and under certain stated conditions.

In October 2006, GeoVax and our subsidiary, GeoVax, Inc. entered into indemnification agreements with Messrs. McNally, Reynolds, Kollintzas and Spencer. Pursuant to these agreements, we have agreed to hold harmless and indemnify these directors and officers to the full extent authorized or permitted by applicable Illinois and Georgia law against certain expenses and other liabilities actually and reasonably incurred by these individuals in connection with certain proceedings if they acted in a manner they believed in good faith to be in or not opposed to the best interests of the Company and, with respect to any criminal proceeding, had no reasonable cause to believe that such conduct was unlawful. The agreements also provide for the advancement of expenses to these individuals subject to specified conditions. Under these agreements, we will not indemnify these individuals for expenses or other amounts for which applicable Illinois and Georgia law prohibit indemnification. The obligations under these agreements continue during the period in which these individuals are our directors or officers and continue thereafter so long as these individuals shall be subject to any proceeding by reason of their service to the Company, whether or not they are serving in any such capacity at the time the liability or expense incurred for which indemnification can be provided under the agreements.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION
FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed 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 a director, officer or controlling person 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, 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 such issue.

55

PLAN OF DISTRIBUTION

Each selling stockholder and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the OTC Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling securities:

| ● | ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
| ● | block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
| ● | purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
| ● | an exchange distribution in accordance with the rules of the applicable exchange;
| ● | privately negotiated transactions;
| ● | settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;
| ● | in transactions through broker-dealers that agree with the selling stockholder to sell a specified number of such securities at a stipulated price per security;
| ● | through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
| ● | a combination of any such methods of sale; or
| ● | any other method permitted pursuant to applicable law.

The selling stockholders may also sell securities under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with Financial Industry Regulation Authority (FINRA) Rule 2121.

In connection with the sale of the securities or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The selling stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because selling stockholders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. The selling stockholders have advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale securities by the selling stockholders.

56

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144 (assuming a cashless exercise of each Series A, B, and C Warrant), without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities offered hereby have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M under the Securities Act, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

LEGAL MATTERS

The validity of the securities offered by this prospectus will be passed upon by Womble Carlyle Sandridge & Rice LLP, Atlanta, Georgia.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 20 15

(unaudited)

1. Description of Company

GeoVax Labs, Inc. (“GeoVax” or the “Company”), is a clinical-stage biotechnology company developing human vaccines using our novel platform technology. Our current development programs are focused on vaccines against Ebola and Marburg viruses, and Human Immunodeficiency Virus (HIV). Our vaccine delivery technology generates virus-like particles (VLPs) that are effective at eliciting safe and effective immune responses. Our proprietary Ebola vaccine technology has been developed internally using technology licensed from the National Institutes of Health (NIH), while our HIV vaccine technology was developed in collaboration with Emory University, the NIH, and the Centers for Disease Control and Prevention (CDC) and is exclusively licensed to us. GeoVax is incorporated under the laws of the State of Delaware and our principal offices are located in Smyrna, Georgia.

2. Basis of Presentation

The accompanying condensed consolidated financial statements at September 30, 2015 and for the three-month and nine-month periods ended September 30, 2015 and 2014 are unaudited, but include all adjustments, consisting of normal recurring entries, which we believe to be necessary for a fair presentation of the dates and periods presented. Interim results are not necessarily indicative of results for a full year. The financial statements should be read in conjunction with our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014. We expect our operating results to fluctuate for the foreseeable future; therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.

Our financial statements have been prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of the financial statements. We are devoting substantially all of our present efforts to research and development of our vaccine candidates. We have funded our activities to date from government grants and clinical trial assistance, and from sales of our equity securities. We will continue to require substantial funds to continue our research and development activities. We believe that our existing cash resources and grant commitments will be sufficient to fund our planned operations through the first quarter of 2016, but due to our history of operating losses and our continuing need for capital to conduct our research and development activities, there is substantial doubt concerning our ability to operate as a going concern beyond that date. We are currently exploring sources of capital through government grants and clinical trial support and through philanthropic foundation support. We may also secure additional funds through sales of our equity securities or the exercise of currently outstanding stock purchase warrants. Management believes that the Company’s demonstrated history of successful funding through both government sources and equity securities alleviate the substantial doubt about the Company’s ability to operate as a going concern. However, additional funding may not be available on favorable terms or at all. If we fail to obtain additional capital when needed, we may be required to delay, scale back, or eliminate some or all of our research and development programs as well as reduce our general and administrative expenses.

3. Significant Accounting Policies and Recent Accounting Pronouncements

We disclosed in Note 2 to our financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014 those accounting policies that we consider significant in determining our results of operations and financial position. There have been no material changes to, or in the application of, the accounting policies previously identified and described in the Form 10-K.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which creates a new Topic, Accounting Standards Codification Topic 606. The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for the Company beginning in 2017 and allows for either full retrospective adoption or modified retrospective adoption. We are currently evaluating the impact of the adoption of ASU 2014-09 on our financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements during the nine-month period ended September 30, 2015 which we expect to have a material impact on our financial statements.

F-5

4. Basic and Diluted Loss Per Common Share

Basic net loss per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted-average number of common shares and potentially dilutive common share equivalents outstanding during the period. Potentially dilutive common share equivalents consist of convertible preferred stock, stock options and stock purchase warrants. Common share equivalents which potentially could dilute basic earnings per share in the future, and which were excluded from the computation of diluted loss per share, as the effect would be anti-dilutive, totaled approximately 79.0 million and 12.5 million shares at September 30, 2015 and 2014, respectively.

5. Property and Equipment

Property and equipment as shown on the accompanying Condensed Consolidated Balance Sheets is composed of the following as of September 30, 2015 and December 31, 2014:

|  | September 30, 2015 |  |  | December 31, 2014 |
Laboratory equipment |  | $ | 525,956 |  |  | $ | 510,106 |
Leasehold improvements |  |  | 115,605 |  |  |  | 115,605 |
Other furniture, fixtures & equipment |  |  | 28,685 |  |  |  | 28,685 |
Total property and equipment |  |  | 670,246 |  |  |  | 654,396 |
Accumulated depreciation and amortization |  |  | (579,404 | ) |  |  | (557,703 | )
Property and equipment, net |  | $ | 90,842 |  |  | $ | 96,693 |

6. Commitments

Lease Agreement

We lease approximately 8,400 square feet of office and laboratory space located in Smyrna, Georgia, pursuant to an operating lease which expires on December 31, 2016, an additional 12-month renewal option. As of September 30, 2015, our future minimum lease payments for the current lease term (excluding the renewal option) total $36,523 for the remainder of 2015, and $149,042 for 2016.

Other Commitments

In the normal course of business, we may enter into various firm purchase commitments related to production and testing of our vaccine material, conduct of our clinical trials, and other research-related activities. As of September 30, 2015, we had approximately $36,200 of unrecorded outstanding purchase commitments to our vendors and subcontractors, all of which we expect will be due in 2015.

7. Preferred Stock

Series B Convertible Preferred Stock

As of September 30, 2015, there are 100 shares of our Series B Convertible Preferred Stock outstanding (issued in December 2013), convertible into 285,714 shares of our common stock. During the nine-month period ended September 30, 2015, there were no conversions or other transactions involving our Series B Convertible Preferred Stock.

Series C Convertible Preferred Stock

In February 2015, we established from the authorized preferred stock a series of preferred stock, consisting of 3,000 shares of Series C Convertible Preferred Stock, $1,000 stated value (“Series C Preferred Shares”) and entered into a Securities Purchase Agreement (“SPA”) whereby we issued to two institutional investors (“Purchasers”) the Series C Preferred Shares for gross proceeds of $3.0 million. Net proceeds to the Company from this transaction, after deduction of placement agent fees and other expenses, were approximately $2.7 million.

The Series C Preferred Shares may be converted at any time at the option of the Purchasers into shares of our common stock. The initial conversion price of the Series C Preferred Shares was $0.18 per share (“Conversion Price”). The Series C Preferred Shares have a liquidation preference equal to the initial purchase price, have no voting rights, and are not entitled to a dividend. The Series C Preferred Shares contains price adjustment provisions, which may, under certain circumstances, reduce the Conversion Price on several future dates according to a formula based on the then-current market price for our common stock. As discussed below, on April 8, 2015 the Conversion Price was adjusted to $0.142 per share resulting in an aggregate total of 21,126,760 shares of our common stock (“Conversion Shares”) into which the Series C Preferred Shares currently may be converted.

F-6

Pursuant to the terms of the SPA, we issued to each Purchaser Series D, E and F Warrants (collectively, the “Investor Warrants”), each to purchase up to a number of shares of our common stock equal to 100% of the Conversion Shares underlying the Series C Preferred Shares (up to 16,666,666 shares in the aggregate for each of the three series of warrants, or 49,999,998 shares in total). The Series D Warrants had an initial exercise price of $0.22 per share, are currently exercisable, and have a term of exercise equal to five years from the date of issuance. The Series E Warrants had an initial exercise price of $0.18 per share, are currently exercisable, and have a term of exercise equal to one year from the date of issuance. The Series F Warrants had an initial exercise price of $0.22 per share and have a term of exercise equal to five years from the date of issuance, but only vest and become exercisable upon, and in proportion to, the exercise of the one-year Series E Warrants. We also issued to our placement agent warrants (“Placement Agent Warrants”) to acquire 1,333,333 shares of our Common Stock with terms substantially the same as the Series D Warrants. The Investor Warrants and Placement Agent Warrants contain anti-dilution and price adjustment provisions, which may, under certain circumstances, (i) reduce the exercise price on several future dates according to a formula based on the then-current market price for our common stock and (ii) reduce the exercise price to match if we sell or grant options to purchase, including rights to reprice, our common stock or common stock equivalents at a price lower than the exercise price of the warrants, or if we announce plans to do so. The number of shares subject to warrants will not increase due to such reductions in exercise price.

In connection with the sale of the Series C Preferred Shares, we entered into a Registration Rights Agreement (“RRA”) with the Purchasers, pursuant to which we filed a registration statement with the Securities and Exchange Commission (“SEC”) on March 20, 2015. It was declared effective by the SEC on April 8, 2015, which triggered the price adjustment provisions of the Series C Preferred Shares and the related warrants. As of that date, the conversion price of the Series C Preferred Shares was reduced to $0.142, the exercise price of the Series E Warrants was reduced to $0.142, and the exercise price of the Series D Warrants, Series F Warrants and Placement Agent Warrants was reduced to $0.1704.

Accounting Treatment and Allocation of Proceeds. We first assessed the Series C Preferred Shares under ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”) and determined such preferred stock not to be a liability under ASC 480. We next assessed the preferred stock under ASC Topic 815. “Derivatives and Hedging” (“ASC 815”). The preferred stock contains an embedded feature allowing an optional conversion by the holder into common stock which meets the definition of a derivative. However, we believe that the preferred stock is an “equity host” (as described by ASC 815) for purposes of assessing the embedded derivative for potential bifurcation and determined that the optional conversion feature is clearly and closely associated to the preferred stock host; we therefore determined that the embedded derivative does not require bifurcation and separate recognition under ASC 815. We then assessed the preferred stock under ASC Topic 470, “Debt” (“ASC 470”), and determined there to be no beneficial conversion feature (“BCF”) requiring recognition at the issuance date. We also assessed the warrants issued in connection with the financing under ASC 815 and determined that they do not initially meet the definition of a derivative, but will require evaluation on an on-going basis.

The following is a summary of the allocation of the net proceeds from the preferred stock financing:

Net proceeds after transaction costs |  | $ | 2,679,809 |
Less: Fair value of warrants (recorded to Additional Paid-in Capital) |  |  | (1,695,868 | )
Recorded value of Series C Preferred Shares at September 30, 2015 |  | $ | 983,941 |

8. Common Stock

Increase in Authorized Shares of Common Stock

At our annual meeting of stockholders held on May 12, 2015, our stockholders approved an amendment to our certificate of incorporation to increase our authorized shares of common stock from 75,000,000 shares to 150,000,000 shares. The amendment to our certificate of incorporation was filed with the Delaware Secretary of State on May 13, 2015.

Common Stock Transactions

During the nine-month period ended September 30, 2015, there were no transactions involving our Common Stock.

F-7

Stock Options

Stock-Based Compensation Expense

During the three-month and nine-month periods ended September 30, 2015 and 2014, we recorded stock-based compensation expense as follows:

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |
Stock Option Expense |  | $ | 16,926 |  |  | $ | 24,573 |  |  | $ | 50,516 |  |  | $ | 75,927 |
Common Stock Issued for Services |  |  | - |  |  |  | - |  |  |  | - |  |  |  | 50,000 |
Warrant Modification Expense |  |  | - |  |  |  | - |  |  |  | - |  |  |  | 39,711 |
Total Stock-Based Compensation Expense |  | $ | 16,926 |  |  | $ | 24,573 |  |  | $ | 50,516 |  |  | $ | 165,638 |

Stock-based compensation expense related to stock options is recognized on a straight-line basis over the requisite service period for the award and is allocated to research and development expense or general and administrative expense based upon the related employee classification. As of September 30, 2015, there was $64,330 of unrecognized compensation expense related to stock options, which is expected to be recognized over a weighted average period of 1.5 years.

Common Stock Reserved

A summary of our common stock reserved for future issuance is as follows as of September 30, 2015:

Series B Convertible Preferred Stock |  |  | 285,714 |
Series C Convertible Preferred Stock |  |  | 21,126,760 |
Common Stock Purchase Warrants |  |  | 56,442,157 |
Equity Incentive Plans |  |  | 1,197,529 |
Total |  |  | 79,052,160 |

9. Income Taxes

Because of our historically significant net operating losses, we have not paid income taxes since inception. We maintain deferred tax assets that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. These deferred tax assets are comprised primarily of net operating loss carryforwards and also include amounts relating to nonqualified stock options and research and development credits. The net deferred tax asset has been fully offset by a valuation allowance because of the uncertainty of our future profitability and our ability to utilize the deferred tax assets. Utilization of operating losses and credits may be subject to substantial annual limitations due to ownership change provisions of Section 382 of the Internal Revenue Code. The annual limitation may result in the expiration of net operating losses and credits before utilization.

F-8

10. Government Grants

We record revenue associated with government grants as the related costs and expenses are incurred and such revenue is reported as a separate line item in our statements of operations. Grant revenues recorded during the three-month and nine-month periods ended September 30, 2015 and 2014 relate to grants from the NIH in support of our HIV vaccine development activities. As of September 30, 2015, there is $260,522 of approved grant funds remaining and available for use, which we anticipate recognizing as revenue during the remainder of 2015 and the first half of 2016.

11. Related Party Transactions

We are obligated to reimburse Emory University (a significant stockholder of the Company) for certain prior and ongoing costs in connection with the filing, prosecution and maintenance of patent applications subject to our technology license agreement from Emory. During the three-month and nine-month periods ended September 30, 2015, we recorded $30,785 and $94,690, respectively, of general and administrative expense associated with these patent cost reimbursements to Emory, as compared to $19,757 and $135,150, respectively, for the same periods in 2014.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors

GeoVax Labs, Inc.

Atlanta, Georgia

We have audited the accompanying consolidated balance sheets of GeoVax Labs, Inc. and subsidiary (the “Company”) as of December 31, 2014 and 2013, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014. Our audits also included the financial statement schedule of the Company listed in Item 15(a). These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion of the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of GeoVax Labs, Inc. and subsidiary as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended December 31, 2014, 2013 and 2012

1. | Description of Business

GeoVax Labs, Inc. (“GeoVax” or the “Company”), is a clinical-stage biotechnology company developing innovative human vaccines using our novel DNA/MVA platform technology. Our lead programs are focused on Ebola virus and Human Immunodeficiency Virus (HIV). Our vaccine delivery technology generates virus-like particles (VLPs) that are effective at eliciting safe and effective immune responses. All of the clinical trials for our preventive HIV vaccine have been conducted by the HIV Vaccine Trials Network (HVTN) with funding from the National Institutes of Health (NIH). Our proprietary Ebola vaccine technology has been developed internally, while our HIV vaccine technology was developed in collaboration with Emory University, the NIH, and the Centers for Disease Control and Prevention (CDC) and is exclusively licensed to us.

Our most advanced vaccines under development address the clade B subtype of the HIV virus that is most prevalent in the developed world – primarily North America and Western Europe. Our preventive clade B HIV vaccine has successfully completed Phase 2a clinical trials and we are currently planning the next stage of human clinical testing. We are also planning clinical trials to evaluate our clade B HIV vaccine as an immunotherapy agent for individuals already infected with HIV. We have begun early-stage preclinical studies to develop HIV vaccine candidates for the clade C subtype of HIV prevalent in the developing world. Our Ebola vaccine development efforts were initiated in 2014 and we expect to conduct preclinical animal studies during 2015, with the goal of beginning human clinical testing in 2016.

We operate in a highly regulated and competitive environment. The manufacturing and marketing of pharmaceutical products require approval from, and are subject to, ongoing oversight by the Food and Drug Administration (FDA) in the United States, by the European Medicines Agency (EMA) in the European Union, and by comparable agencies in other countries. Obtaining approval for a new pharmaceutical product is never certain and may take many years and may involve expenditure of substantial resources. Our goal is to build a profitable company by generating income from products we develop and commercialize, either alone or with one or more potential strategic partners.

GeoVax is incorporated under the laws of the State of Delaware and our principal offices are located in Smyrna, Georgia (metropolitan Atlanta area).

2. | Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of GeoVax Labs, Inc. together with those of our wholly-owned subsidiary, GeoVax, Inc. All intercompany transactions have been eliminated in consolidation.

Basis of Presentation

The accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of these consolidated financial statements. We are devoting substantially all of our present efforts to research and development. We have funded our activities to date from government grants and clinical trial assistance, and from sales of our equity securities. We will continue to require substantial funds to continue these activities. We believe that our existing cash resources, combined with the proceeds from the NIH grants discussed in Note 5 and the net proceeds of the financing transaction discussed in Note 14, will be sufficient to fund our planned operations through the first quarter of 2016.

We expect we will need to raise additional funds to significantly advance our vaccine development programs and we are currently exploring sources of non-dilutive capital through government grant programs and clinical trial support. However, additional funding may not be available on favorable terms or at all. If we fail to obtain additional capital when needed, we may be required to delay, scale back, or eliminate some or all of our research and development programs as well as reduce our general and administrative expenses.

In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-15, Presentation of Financial Statements – Going Concern (“ASU 2014-15”), which requires management of all entities to evaluate whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements are issued, and to make certain disclosures if it concludes that substantial doubt exists or when its plans alleviate substantial doubt about the entity’s ability to continue as a going concern. ASU 2014-15 is effective for the Company for annual reporting periods beginning in 2016 and for interim reporting periods starting in the first quarter of 2017. We are currently evaluating the impact of the adoption of ASU 2014-15 on our financial statements.

F-15

Development-Stage Enterprise

In June 2014, the FASB issued Accounting Standards Update 2014-10, Development Stage Entities (Topic 915) ("ASU 2014-10"). The amendments in ASU 2014-10 remove the definition of a development stage entity from Topic 915, thereby removing the distinction between development stage entities and other reporting entities from U.S. generally accepted accounting principles (“GAAP”). In addition, the amendments eliminate the requirements for development stage entities to (1) present inception-to-date information on the statements of income, cash flows, and shareholder’s equity, (2) label the financial statements as those of a development stage entity, (3) disclose a description of the development stage activities in which the entity is engaged, and (4) disclose in the first year in which the entity is no longer a development stage entity that in prior years it had been in the development stage. For public business entities, those amendments are effective for annual reporting periods beginning after December 15, 2014, and interim periods therein. Early adoption is permitted. We have evaluated this accounting standard and determined it to have a material impact on our financial statements. We adopted ASU-2014-10 effective June 30, 2014 and the effects of the adoption are reflected in our consolidated financial statements and footnotes contained herein.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

Cash and Cash Equivalents

We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Our cash and cash equivalents consist primarily of bank deposits and money market accounts. The recorded values approximate fair market values due to the short maturities.

Fair Value of Financial Instruments and Concentration of Credit Risk

Financial instruments that subject us to concentration of credit risk consist primarily of cash and cash equivalents, which are maintained by a high credit quality financial institution. The carrying values reported in the balance sheets for cash and cash equivalents approximate fair values.

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to operations as incurred, while additions and improvements are capitalized. We calculate depreciation using the straight-line method over the estimated useful lives of the assets which range from three to five years. We amortize leasehold improvements using the straight-line method over the term of the related lease.

Impairment of Long-Lived Assets

We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by such assets. If we consider such assets to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the expected future net cash flows from the assets.

F-16

Accrued Liabilities

As part of the process of preparing our financial statements, we estimate expenses that we believe we have incurred, but have not yet been billed by our third party vendors. This process involves identifying services and activities that have been performed by such vendors on our behalf and estimating the level to which they have been performed and the associated cost incurred for such service as of each balance sheet date.

Net Loss Per Share

Basic and diluted loss per common share are computed based on the weighted average number of common shares outstanding. Common share equivalents consist of common shares issuable upon conversion of convertible preferred stock, and upon exercise of stock options and stock purchase warrants. All common share equivalents are excluded from the computation of diluted loss per share since the effect would be anti-dilutive. Common share equivalents which could potentially dilute basic earnings per share in the future, and which were excluded from the computation of diluted loss per share, totaled approximately 6.6 million, 14.4 million, and 13.3 million at December 31, 2014, 2013 and 2012, respectively.

Revenue Recognition

We recognize revenue in accordance with U.S. Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, as amended by Staff Accounting Bulletin No. 104, Revenue Recognition, (“SAB 104”). SAB 104 provides guidance in applying GAAP to revenue recognition issues, and specifically addresses revenue recognition for upfront, nonrefundable fees received in connection with research collaboration agreements. During 2014, 2013 and 2012, our revenue consisted of grant funding received from the NIH (see Note 5). Revenue from these arrangements is approximately equal to the costs incurred and is recorded as income as the related costs are incurred.

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which creates a new Topic, Accounting Standards Codification Topic 606. The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for the Company beginning in 2017 and allows for either full retrospective adoption or modified retrospective adoption. We are currently evaluating the impact of the adoption of ASU 2014-09 on our financial statements.

Research and Development Expense

Research and development expense primarily consists of costs incurred in the discovery, development, testing and manufacturing of our product candidates. These expenses consist primarily of (i) fees paid to third-party service providers to perform, monitor and accumulate data related to our preclinical studies and clinical trials, (ii) costs related to sponsored research agreements, (iii) the costs to procure and manufacture materials used in clinical trials, (iv) laboratory supplies and facility-related expenses to conduct development, and (v) salaries, benefits, and stock-based compensation for personnel. These costs are charged to expense as incurred.

Patent Costs

Our expenditures relating to obtaining and protecting patents are charged to expense when incurred, and are included in general and administrative expense.

Period to Period Comparisons

Our operating results are expected to fluctuate for the foreseeable future. Therefore, period-to-period comparisons should not be relied upon as predictive of the results for future periods.

Income Taxes

We account for income taxes using the liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted rates in effect for the year in which temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance unless, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will be realized.

F-17

Stock-Based Compensation

We account for stock-based transactions in which the Company receives services from employees, directors or others in exchange for equity instruments based on the fair value of the award at the grant date. Compensation cost for awards of common stock is estimated based on the price of the underlying common stock on the date of issuance. Compensation cost for stock options or warrants is estimated at the grant date based on each instrument’s fair value as calculated by the Black-Scholes option pricing model. We recognize stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period for the award. See Note 9 for additional stock-based compensation information.

Recent Accounting Pronouncements

Except as discussed above, there have been no recent accounting pronouncements or changes in accounting pronouncements which we expect to have a material impact on our financial statements, nor do we believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on our financial statements.

3. | Property and Equipment

Property and equipment as shown on the accompanying Consolidated Balance Sheets is composed of the following as of December 31, 2014 and 2013:

|  | 2014 |  |  | 2013 |

Amortization expense related to technology licenses was $10,000, $10,000, and $19,923 during the years ended December 31, 2014, 2013 and 2012, respectively.

5. | Government Grants

We record revenue associated with government grants as the related costs and expenses are incurred and such revenue is reported as a separate line item in our statements of operations. Grant revenues relate to grants from the NIH in support of our HIV vaccine development activities. During 2014, 2013, and 2012, we recorded $882,956, $2,417,550, and $2,657,327, respectively, of revenue associated with these grants. Additional detail concerning our grant revenues is discussed below.

F-18

In September 2007, the NIH awarded us a grant entitled “GM-CSF-Adjuvanted Clade C DNA/MVA and MVA/MVA Vaccines”. The aggregate award (including subsequent amendments) totaled approximately $20.4 million. We recorded grant revenues of $624,689, $833,390, and $2,227,924 for the years ended December 31, 2014, 2013 and 2012, respectively, related to this grant, and there is $75,464 of unrecognized grant funds remaining and available for use pursuant to this grant as of December 31, 2014.

In September 2012, the NIH awarded us a grant entitled “Immunogens and Manufacturing” to support our HIV/AIDS vaccine development program. The grant award was for approximately $1.9 million. We recorded grant revenues of $-0-, $1,429,597, and $429,403 for the years ended December 31, 2014, 2013 and 2012, respectively, related to this grant, and all funding pursuant to this grant has been utilized as of December 31, 2014.

In July 2013, the NIH awarded us a Small Business Innovative Research (SBIR) grant entitled “Enhancing Protective Antibody Responses for a GM-CSF Adjuvanted HIV Vaccine.” The initial grant award was $276,690 for the first year of a two year project period beginning August 1, 2013. In July 2014, the NIH awarded us $289,641 for the second year of the project period. We recorded grant revenues of $258,267, $154,563, and $-0- for the years ended December 31, 2014, 2013 and 2012, respectively, related to this grant, and there is $153,501 of unrecognized grant funds remaining and available for use pursuant to this grant as of December 31, 2014.

6. | Commitments

Lease Agreements

We lease approximately 8,400 square feet of office and laboratory space located in Smyrna, Georgia (metropolitan Atlanta). Rent expense for the years ended December 31, 2014, 2013 and 2012 was $117,084, $117,879, and $118,801, respectively. The original 62-month lease term expired on December 31, 2014 and we have renewed the lease for an additional 12 months, with two successive 12-month renewal options. Future minimum lease payments total $146,092 in 2015.

Other Commitments

In the normal course of business, we may enter into various firm purchase commitments related to production and testing of our vaccine material, conduct of clinical trials, and other research-related activities. As of December 31, 2014, we had approximately $151,439 of unrecorded outstanding purchase commitments to our vendors and subcontractors, all of which we expect will be due in 2015.

7. | Preferred Stock

Series A Convertible Preferred Stock

In March 2012, we issued 2,200 shares of our Series A Convertible Preferred Stock, $1,000 stated value (“Series A Preferred Stock”), which were originally convertible into 2,933,333 shares of our common stock, and warrants to purchase up to 8,799,999 shares of our common stock for gross proceeds of $2.2 million. Net proceeds, after deduction of placement agent fees and other expenses, were approximately $2.0 million.

Each share of Series A Preferred Stock was entitled to a liquidation preference equal to the initial purchase price, had no voting rights, and was not entitled to a dividend. The Series A Preferred Stock was convertible at any time at the option of the holders into shares of our common stock. The initial conversion price was $0.75 and during 2012, 1,412 of the Series A Preferred Shares were converted at this price into an aggregate of 1,882,667 shares of our common stock. Effective December 11, 2013, we amended the designation of the Series A Preferred Stock in connection with the issuance of our Series B Convertible Preferred Stock (see discussion below). The amendment had the effect of reducing the conversion price of the then-outstanding Series A Preferred Stock to $0.35 and during the remainder of 2013, 717 shares of the Series A Preferred Stock were converted at this price into an aggregate of 2,048,570 shares of our common stock. The remaining 71 shares of Series A Preferred Stock were converted into 202,857 shares of our common stock in January 2014, and there are no shares of Series A Preferred Stock outstanding at December 31, 2014.

We assessed the Series A Preferred Stock and the related warrants under ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”), ASC Topic 815, “Derivatives and Hedging” (“ASC 815”), and ASC Topic 470, “Debt” (“ASC 470”). The preferred stock contains an embedded feature allowing an optional conversion by the holder into common stock which meets the definition of a derivative. However, we determined that the preferred stock is an “equity host” (as described by ASC 815) for purposes of assessing the embedded derivative for potential bifurcation and that the optional conversion feature is clearly and closely associated to the preferred stock host; therefore the embedded derivative does not require bifurcation and separate recognition under ASC 815. We determined there to be a beneficial conversion feature (“BCF”) requiring recognition at its intrinsic value. Since the conversion option of the preferred stock was immediately exercisable, the amount allocated to the BCF was immediately accreted to preferred dividends, resulting in an increase in the carrying value of the preferred stock. We also assessed the warrants issued in connection with the financing under ASC 815 and determined that they did not initially meet the definition of a derivative, but will require evaluation on an on-going basis. As of December 31, 2014, we determined that the warrants still did not meet the definition of a derivative.

The following is a summary of the allocation of net proceeds and reconciliation to the carrying value of the Series A Preferred Stock at December 31, 2014:

Net proceeds |  | $ | 1,999,032 |

Series B Convertible Preferred Stock

In December 2013, we issued 1,650 shares of our Series B Convertible Preferred Stock, $1,000 stated value (“Series B Preferred Stock”), which was originally convertible into 4,714,286 shares of our common stock, for gross proceeds of $1.65 million. Net proceeds, after deduction of transaction expenses, were approximately $1.6 million. No warrants were issued in connection with the transaction.

Each share of Series B Preferred Stock has a liquidation preference equal to the initial purchase price, has no voting rights, and is not entitled to a dividend. The Series B Preferred Stock may be converted at any time at the option of the holders into shares of our common stock at a conversion price of $0.35. During 2014, 1,550 shares of the Series B Preferred Stock were converted into 4,428,571 shares of our common stock. As of December 31, 2014, there were 100 shares of Series B Preferred Stock outstanding, convertible into 285,714 shares of our common stock.

In conjunction with the issuance of the Series B Preferred Stock, we entered into an agreement with the holders of the Series A Preferred Stock to amend the designation of the Series A Preferred Stock. The amendment had the effect of reducing the conversion price of the then-outstanding 788 Series A Preferred Shares from $0.75 to $0.35.

We assessed the Series B Preferred Stock using the same methodology as for the Series A Preferred Stock (see discussion above), and resulting in the same determinations. The following is a summary of the allocation of net proceeds and reconciliation to the carrying value of the Series B Preferred Stock at December 31, 2014:

Net proceeds |  | $ | 1,615,798 |
Beneficial conversion feature – Series A Preferred Stock (recorded to Additional Paid-in Capital) |  |  | (360,229 | )

Stock Purchase Warrants

As of December 31, 2014, we have the following stock purchase warrants outstanding:

Expiration Date |  | Number of Shares |  |  | Weighted Average Exercise Price |
December 31, 2016 |  |  | 1,806,159 |  |  | $ | 1.00 |
January 16, 2017 |  |  | 45,000 |  |  |  | 1.00 |

Total Outstanding at December 31, 2014 |  |  | 5,108,826 |  |  | $ | 0.66 |

During January 2013, we reduced the exercise price of warrants to purchase 2,933,333 shares of our common stock from $0.75 to $0.60 per share. In consideration for the reduction of the exercise price, the holders of the warrants immediately exercised 1,766,667 of the warrants for cash, resulting in total proceeds to the Company of $1,060,000. We also extended the expiration date of the 1,166,666 unexercised warrants from March 21, 2013 to May 21, 2013. We recorded general and administrative expense of $218,551 associated with these warrant modifications. During May 2013, we reduced the exercise price of the 1,166,666 remaining warrants from $0.60 to $0.50 per share. In consideration for the reduction of the exercise price, the holders of the warrants immediately exercised all of the remaining warrants for cash, resulting in total proceeds to the Company of $583,333. We recorded general and administrative expense of $19,617 associated with this warrant modification.

During September 2014, we reduced the exercise price of warrants to purchase 818,376 shares of our common stock from $16.50 to $1.00 per share, and extended the expiration dates from December 31, 2014 to December 31, 2016. We recorded general and administrative expense of $39,711 associated with these modifications.

During October 2014, we entered into an agreement with certain holders of warrants to purchase shares of our common stock with respect to the payment to them of a warrant exercise fee of $0.075 per share for each share purchased upon exercise of warrants held by them. In exchange for the fee, they immediately exercised warrants for an aggregate of 3,176,000 shares of our common stock, resulting in proceeds to us of $873,400 (net of the exercise fee).

9. | Stock-Based Compensation

Stock Option Plan

In 2006, we adopted the GeoVax Labs, Inc. 2006 Equity Incentive Plan (the “Stock Option Plan”) for the granting of qualified incentive stock options (“ISO’s”), nonqualified stock options, restricted stock awards or restricted stock bonuses to employees, officers, directors, consultants and advisors of the Company. The exercise price for any option granted may not be less than fair value (110% of fair value for ISO’s granted to certain employees). Options granted under the Stock Option Plan have a maximum ten-year term and generally vest over three years. The Company has reserved 1,200,000 shares of its common stock for issuance under the Stock Option Plan.

Certain information concerning the Stock Option Plan as of December 31, 2014, and a summary of activity during the year then ended is presented below:

|  | Number of Shares |  |  | Weighted- Average Exercise Price |  |  | Weighted- Average Remaining Contractual Term (yrs) |  |  | Aggregate Intrinsic Value |

Additional information concerning our stock options for the years ended December 31, 2014, 2013 and 2012 is as follows:

|  | 2014 |  |  | 2013 |  |  | 2012 |
Weighted average fair value of options granted |  | $ | 0.14 |  |  | $ | 0.43 |  |  | $ | 0.59 |
Intrinsic value of options exercised |  |  | -0- |  |  |  | -0- |  |  |  | -0- |
Total fair value of options vested |  |  | 97,707 |  |  |  | 165,490 |  |  |  | 319,920 |

We use the Black-Scholes model for determining the grant date fair value of our stock option grants. This model utilizes certain information, such as the interest rate on a risk-free security with a term generally equivalent to the expected life of the option being valued and requires certain other assumptions, such as the expected amount of time an option will be outstanding until it is exercised or expired, to calculate the fair value of stock options granted. The significant assumptions we used in our fair value calculations were as follows:

|  | 2014 |  |  | 2013 |  |  | 2012 |
Weighted average risk-free interest rates |  |  | 1.98 | % |  |  | 2.3 | % |  |  | 1.1 | %
Expected dividend yield |  |  | 0.0 | % |  |  | 0.0 | % |  |  | 0.0 | %
Expected life of option (years) |  |  | 7.0 |  |  |  | 7.0 |  |  |  | 6.7 |

Other Non-E mp loyee Stock-Based C ompensation

We recorded general and administrative expense of $100,000, $20,500, and $-0- during the years ended December 31, 2014, 2013 and 2012, respectively, related to the issuance of our common stock in exchange for services rendered by non-employees (See Note 8 – “Common Stock Transactions”).

During 2014, we recorded general and administrative expense of $238,200 related to a warrant exercise fee paid to certain holders of our stock purchase warrants as an incentive for the holders to immediately certain warrants (see Note 8 – “Stock Purchase Warrants”).

As of December 31, 2014, there was no unrecognized expense related to any non-employee stock-based compensation arrangements.

10. | Retirement Plan

We participate in a multi-employer defined contribution retirement plan (the “401k Plan”) administered by a third party service provider; and the Company contributes to the 401k Plan on behalf of its employees based upon a matching formula. During the years ended December 31, 2014, 2013 and 2012 our contributions to the 401k Plan were $35,567, $43,132, and $50,500, respectively.

11. | Income Taxes

At December 31, 2014, we have a consolidated federal net operating loss (“NOL”) carryforward of approximately $64.6 million, available to offset against future taxable income which expires in varying amounts in 2019 through 2034. Additionally, we have approximately $826,000 in research and development (“R&D”) tax credits that expire in 2022 through 2034 unless utilized earlier. No income taxes have been paid to date.

Section 382 of the Internal Revenue Code contains provisions that may limit our utilization of our NOL and R&D tax credit carryforwards in any given year as a result of significant changes in ownership interests that have occurred in past periods or may occur in future periods.

Deferred income taxes reflect the net effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred tax assets and liabilities included the following at December 31, 2014 and 2013:

|  | 2014 |  |  | 2013 |
Deferred tax assets: |  |  |  |  |  |  |  |
Net operating loss carryforward |  | $ | 22,831,626 |  |  | $ | 21,983,109 |
Research and development tax credit carryforward |  |  | 825,896 |  |  |  | 799,248 |
Stock-based compensation expense |  |  | 2,396,805 |  |  |  | 2,233,909 |
Total deferred tax assets |  |  | 26,054,327 |  |  |  | 25,016,266 |
Deferred tax liabilities |  |  |  |  |  |  |  |
Depreciation |  |  | (7,149 | ) |  |  | (13,386 | )
Total deferred tax liabilities |  |  | (7,149 | ) |  |  | (13,386 | )
Net deferred tax assets |  |  | 26,047,178 |  |  |  | 25,002,881 |
Valuation allowance |  |  | (26,047,178 | ) |  |  | (25,002,881 | )
|  | $ | -0- |  |  | $ | -0- |

We have established a full valuation allowance equal to the amount of our net deferred tax assets due to uncertainties with respect to our ability to generate sufficient taxable income to realize these assets in the future. A reconciliation of the income tax benefit on losses at the U.S. federal statutory rate to the reported income tax expense is as follows:

|  | 2014 |  |  | 2013 |  |  | 2012 |
U.S. federal statutory rate applied to pretax loss |  | $ | (929,409 | ) |  | $ | (776,881 | ) |  | $ | (725,948 | )
Permanent differences |  |  | 1,734 |  |  |  | 3,138 |  |  |  | 2,674 |
Research and development credits |  |  | 26,648 |  |  |  | 14,047 |  |  |  | 21,236 |
Change in valuation allowance |  |  | 901,027 |  |  |  | 759,696 |  |  |  | 702,038 |

Item 14. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law (the “DGCL”), provides, among other things, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the corporation’s request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit or proceeding. The power to indemnify applies (i) if such person is successful on the merits or otherwise in defense of any action, suit or proceeding or (ii) if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The power to indemnify applies to actions brought by or in the right of the corporation as well, but only to the extent of defense expenses (including attorneys’ fees but excluding amounts paid in settlement), actually and reasonably incurred and not to any satisfaction of judgment or settlement of the claim itself, and with the further limitation that in such actions no indemnification shall be made in the event of any adjudication of negligence or misconduct in the performance of his duties to the corporation, unless a court believes that in light of all the circumstances indemnification should apply.

Our bylaws provide that we may indemnify any person 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 (other than an action by or in the right of the Company) by reason of the fact that the person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. Our bylaws also provide that we may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Company to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Company unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

Under our bylaws, expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Company 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 such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Company. Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents may be so paid upon such terms and conditions, if any, as we deem appropriate.

II-1

The indemnification and advancement of expenses provided by our bylaws is not exclusive, both as to action in such person’s official capacity and as to action in another capacity while holding such office.

Our bylaws also provide that we may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Company would have the power to indemnify such person against such liability under our bylaws. The Company maintains an insurance policy providing for indemnification of its officers, directors and certain other persons against liabilities and expenses incurred by any of them in certain stated proceedings and under certain stated conditions.

In October 2006, GeoVax and our subsidiary, GeoVax, Inc. entered into indemnification agreements with Messrs. McNally, Reynolds, Kollintzas and Spencer. Pursuant to these agreements, we have agreed to hold harmless and indemnify these directors and officers to the full extent authorized or permitted by applicable Illinois and Georgia law against certain expenses and other liabilities actually and reasonably incurred by these individuals in connection with certain proceedings if they acted in a manner they believed in good faith to be in or not opposed to the best interests of the Company and, with respect to any criminal proceeding, had no reasonable cause to believe that such conduct was unlawful. The agreements also provide for the advancement of expenses to these individuals subject to specified conditions. Under these agreements, we will not indemnify these individuals for expenses or other amounts for which applicable Illinois and Georgia law prohibit indemnification. The obligations under these agreements continue during the period in which these individuals are our directors or officers and continue thereafter so long as these individuals shall be subject to any proceeding by reason of their service to the Company, whether or not they are serving in any such capacity at the time the liability or expense incurred for which indemnification can be provided under the agreements.

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

Item 15. Recent S ales of Unregistered Securities

On October 22, 2013, we issued 50,000 shares of our common stock to ProActive Capital Resources Group, LLC for services rendered pursuant to a consulting agreement with the Company. For this transaction the Company relied upon Section 4(a)(2) of the Securities Act and Rule 506 promulgated thereunder to issue the common stock. The shares were offered to a single accredited investor who acquired the shares for investment in a transaction that did not involve a general solicitation.

On December 11, 2013, we entered into a Securities Purchase Agreement with three accredited investors identified therein providing for the issuance and sale to the purchasers of an aggregate of 1,650 shares of our Series B convertible preferred stock for gross proceeds to the Company of $1,650,000, as described in our Form 8-K filed December 17, 2013. The Company relied on an exemption from the registration requirements of the Securities Act afforded by Section 4(a)(2) thereof and Rule 506 of Regulation D. For information regarding the terms of the Series B convertible preferred stock, see “Description of Securities” in the prospectus accompanying this registration statement. The accredited investors acquired the shares for investment for their own accounts in a transaction that did not involve a general solicitation.

On July 16, 2014, we issued 250,000 shares of our common stock to Acorn Management Partners, LLC for services rendered pursuant to a consulting agreement with the Company. On November 4, 2014, we issued 128,205 shares of our common stock to Acorn Management Partners, LLC for services rendered pursuant to a consulting agreement with the Company. For these transactions the Company relied upon Section 4(a)(2) of the Securities Act and Rule 506 promulgated thereunder to issue the common stock. The shares were offered to a single accredited investor who acquired the shares for investment in a transaction that did not involve a general solicitation.

II-2

On February 25, 2015, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with two accredited investors providing for the issuance and sale to the investors of an aggregate of 3,000 shares of our Series C Convertible Preferred Stock (the “Series C Preferred Stock”) and related warrants for gross proceeds to the Company of $3.0 million. Each share of Series C Preferred Stock was initially convertible into approximately 5,555.55 shares of our Common Stock for an aggregate total of 16,666,666 shares of our Common Stock (the “Conversion Shares”). The terms of the Preferred Shares include antidilution provisions. We closed this transaction on February 27, 2015. Pursuant to the Securities Purchase Agreement, each investor was also issued a Series D Warrant, a Series E Warrant and a Series F Warrant, each to purchase up to a number of shares of the Company’s Common Stock equal to 100% of the Conversion Shares underlying the Preferred Shares issued to such Purchaser pursuant to the Securities Purchase Agreement (up to 16,666,666 shares in the aggregate for each of the three series of warrants, or approximately 50,000,000 shares in total). Additional detail is set forth in our Form 8-K filed March 2, 2015. The Company also issued a warrant to its placement agent to acquire 1,333,333 shares of our common stock at $0.22 per share on substantially the same terms and conditions of the Series D warrants. The Company relied on an exemption from the registration requirements of the Securities Act afforded by Section 4(a)(2) thereof and Rule 506 of Regulation D. For information regarding the terms of the Series C Preferred Stock, see “Description of Securities” in the prospectus accompanying this registration statement. The accredited investors acquired the shares for investment for their own accounts in a transaction that did not involve a general solicitation.

Item 17. Undertakings

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 Section10(a)(3) of the Securities Act;

| (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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

| (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;

| (2) | That, for purposes of determining any liability under the Securities Act, 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 of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

II-3

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

| (i) | Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

| (ii) | Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

| (iii) | The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

| (iv) | Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

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 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.

The undersigned registrant hereby undertakes that:

| (1) | For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

| (2) | For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of these securities at that time shall be deemed to be the initial bona fide offering.
