ABOUT RIOT BLOCKCHAIN

Company Background

We were incorporated on July 24, 2000 in the State of Colorado under the name AspenBio, Inc., which was subsequently changed to AspenBio Pharma, Inc. In December 2012, we changed our name to Venaxis, Inc. and in 2016, in connection with our acquisition of BiOptix Diagnostics, Inc., we changed our name to Bioptix, Inc. and as of October 19, 2017 we changed our name to Riot Blockchain, Inc., to reflect our new focus on our blockchain business. That operational focus and the Company’s recently completed acquisitions of Kairos Global Technologies, Inc. (“Kairos”) and 1172767 B.C. Ltd., formerly known as Tess Inc., and its investment in goNumerical Ltd., (d/b/a “Coinsquare”), as well as the Company’s new name, reflects a strategic decision by the Company to operate in the blockchain and digital currency related business sector. On March 26, 2018, the Company also acquired 92.5% of Logical Brokerage Corp. (“Logical Brokerage”). Logical Brokerage is a futures introducing broker headquartered in Miami, Florida registered with the Commodity Futures Trading Commission, and a member of the National Futures Association.

In September 2017, we changed our state of incorporation to Nevada from Colorado. Our principal executive offices are located at 202 6th Street, Suite 401, Castle Rock, CO 80104 and our telephone number is (303) 794-2000. Our website address is www.riotblockchain.com. The information contained on, or accessible through, our website is not part of this prospectus.

Management Changes

In 2018, the Company has experienced significant changes to its management and board of directors, including (i) the resignation of its chief executive officer and chairman of the board of directors, John O’Rourke on September 8, 2018, (ii) the subsequent appointment of Christopher Ensey as the Company’s interim chief executive officer, and (iii) the appointment of Remo Mancini as chairman of the board of directors, who had previously served as a member of the board of directors beginning on his appointment in February 2018. Additionally, as of October 22, 2018, Mr. Andrew Kaplan resigned as an independent member of the board of directors. As of October 23, 2018, Mr. Benjamin Yi was appointed to serve as an independent member of the board of directors.

These changes to the management and the board of directors of the Company during 2018 have been made according to the needs and strategic vision of the Company. Management and the board of directors believe these changes will enable the Company to achieve its short- and long-term goals of (1) improving the operational effectiveness of its mining operations, (2) developing its RiotX exchange, and (3) raising additional capital.

Digital Currency Mining Operations

The primary focus of the Company is our digital currency mining operations. Digital currencies are digital or virtual currencies used as a medium of exchange outside of the traditional state-backed fiat currencies. Digital or “crypto” currencies rely on complex cryptographically recorded data entries known as “blocks” on decentralized digital ledger system known as a blockchain. Blocks are added to the blockchain chronologically and, once added, are unchangeable.

Beginning early this year, we relocated our mining operations to our Oklahoma City facility, which is leased by our subsidiary, Kairos. As of the date of this prospectus, we have moved substantially all of our approximately 8,000 digital currency “miners” to our Oklahoma City facility. Kairos leased the Oklahoma City facility from 7725 Reno #1, L.L.C. (“7725 Reno”) by a lease agreement dated February 27, 2018, as amended on March 26, 2018 (the “Lease”). Effective as of November 29, 2018, Kairos amended the Lease with 7725 Reno by: (i) extending the initial term of the Lease through August 15, 2019; (ii) effective as of December 1, 2018, changing the monthly rent for the Lease as follows: (a) $235,000 for December of 2018, (b) $230,000 for January of 2019, and (c) $190,000 per month thereafter for the duration of the Lease, including any renewals; (iii) reducing the monthly electricity usage charges due under the Lease; (iv) providing that Kairos will reimburse 7725 Reno for up to $14,000 of the costs of installing electricity metering devices in the facility; and (v) Kairos will have the option to renew the Lease for up to two (2) three (3) month periods after the expiration of the initial term of the Lease.

The Company’s mining operations focus primarily on bitcoin mining. Bitcoin mining entails solving complex mathematical problems using custom designed and programmed application-specific integrated circuit computers (referred to as miners). Bitcoin miners provide transaction verification services to a given blockchain by solving complex algorithms to encode additional blocks into the blockchain, which blocks serve as immutable records of transactions once added to the blockchain. When a miner is successful in adding a block to the blockchain, it is rewarded with a fixed number of bitcoin. Blocks are added to the blockchain on a first-to-finish basis, meaning that the first miner to solve an algorithm and verify a given transaction is the only miner to receive a bitcoin reward. This first-to-finish environment has created a computing power “arms race” whereby miners are encouraged through competition to allocate ever-increasing computing power (known as “hash rate”) to solving algorithms. The resulting energy costs are substantial, and, in light of the recent decline in the market price of bitcoin and other “benchmark” digital currencies such as bitcoin cash, litecoin, and ethereum, the profitability of mining operations has been reduced as competition increases to solve each block. The Company’s digital currency mining operations operate at a maximum hash rate of 95 petahash per second.

In response to these factors, the Company has entered into mining pools, whereby multiple miners allocate their collective computing powers to solving a given algorithm thereby increasing the collective hash rate devoted to a given algorithm. By pooling their efforts, miners in a pool are more likely to verify a given transaction and add a block to the Blockchain than miners acting individually. Pool miners are awarded a fractional reward based on the hash rate each contributed to the pool on a given transaction, regardless of whether the individual miner actually solved the applicable algorithm. Miners are allocated a share of every reward obtained by the pool, and thus the risk of not solving the algorithm first is reduced. The Company participates in pools on an at-will basis, and is under no obligation to remain in a given pool and may terminate its engagement with a given pool at any time. Presently, management believes participating in mining pools is the most efficient means of mining digital currencies, but is under no obligation, nor does it provide any assurance that it will continue to do so in the future.

Development of a U.S.-based Digital Currency Exchange

In addition to those business developments previously reported by the Company in its annual report on Form 10-K, quarterly reports on Form 10-Q, and periodic reports on Form 8-K, the Company has continued its exploration of the development of a U.S.-based digital currency exchange. The Company’s planned digital currency exchange under the name “RiotX” is being developed by and is contemplated to be operated through the Company’s subsidiary, RiotX Holdings, Inc. The Company believes its development of RiotX could provide a hedge against fluctuations in the price of bitcoin and other digital currencies by providing for the ready exchange of digital currencies similar to how a fiat currency exchange operates. The Company believes that, by providing a stable and secure platform for the exchange of digital currencies, it will attract significant trading volume, thereby providing the Company with consistent revenue per trade, independent of the price of any digital currency.

The Company views its RiotX exchange as being comprised of three core services: (i) Banking Services; (ii) a Trading Engine; and (iii) Digital Wallet Services. The Company intends to provide each of these services by engaging experienced third-party vendors in the industry, which will be reviewed on a case-by-case basis by the Company’s management, along with external advisors and legal counsel; ultimately subject to review by the Company’s board of directors. The Company plans to only contract with companies that have established track records as industry leaders, which comply with federal, state and local laws, and, if required are in compliance with U.S. securities law to provide such services. The Company assesses each vendor using a risk management process that evaluates key risk factors related to their performance and their potential impact on the Company, including, without limitation, its capital structure, financial condition and liquidity. The Company has engaged external advisors and legal counsel to review contracts and conduct due diligence related to financial stability and performance, and cybersecurity procedures. Additionally, the Company assesses each vendor as they relate to its regulatory compliance framework needs such as reporting, fraud monitoring, “know your customer,” anti-money laundering, and data privacy standards to ensure compliance with applicable rules, regulations, and industry best practices.

As the Company continues to explore and develop its planned U.S.-based digital currency exchange, it will continue to develop relationships with additional third party vendors to support the RiotX exchange. As of the date of this prospectus, the Company has entered into several such relationships with third parties to provide RiotX with these core services. As previously reported the Company, through its subsidiary, Logical Brokerage, has entered into a material definitive agreement with Synapse Financial Technologies, Inc. (“SynapseFi”), and its partner, Evolve Bank and Trust, to provide RiotX with banking services and transactional support. As reported in the Company’s press release disclosed on Form 8-K filed on November 28, 2018, the Company’s subsidiary, RiotX Holdings, Inc., entered into a master services agreement with Shift Markets (“Shift”) to provide the Company’s planned U.S.-based digital currency exchange with Shift’s exchange platform. The Company plans to leverage Shift’s proven platform to provide its planned exchange with fast, efficient, and reliable exchange technology. Strategic partnerships with third party vendors like Shift and SynapseFi will provide the Company with necessary services for the development and operation of its planned exchange.

Liquidity and Capital Resources

The Company has experienced recurring losses and negative cash flows from operations. We expect to continue to incur losses from operations for the near-term and these losses could be significant as we incur costs and expenses associated with recent and potential future acquisitions and development of the RiotX exchange platform, as well as public company, legal and administrative related expenses being incurred. We are closely monitoring our cash balances, cash needs and expense levels.

We believe that we will require additional capital either in the form of equity or debt in order for us to meet our obligations arising from normal business operations for the next twelve months. Without additional capital, our ability to continue to operate will be limited. If we are unable to obtain adequate capital, we could be forced to reduce or cease our operations. We are currently pursuing capital transactions in the form of debt and equity; however, we cannot provide any assurance that we will be successful in our plans.

Cash flow from our operations relies substantially on our ability to continue to mine digital currencies and the spot or market price at which our digital currencies are convertible to fiat currency, such as US dollars. We expect to generate ongoing revenues from the production of digital currencies, primarily bitcoins, in our Oklahoma City mining facility. Our ability to liquidate bitcoins at future values above the cost of production will affect our ability to generate positive cash flow from operations.

As of September 30, 2018, the Company had approximate balances of cash and cash equivalents of $1,607,000, a working capital deficit of $1,178,000, total stockholders’ equity of $16,532,000 and an accumulated deficit of $185,796,000. To date, the Company has in large part relied on debt and equity financing to fund its operations. As of the date of this prospectus, the Company has been closely monitoring its cash and cash equivalents and has reduced its operating expenses, as needed, in order to continue to execute the Company’s strategy.

The Company expects it will need to raise additional capital to continue its operations and pursue its growth strategies, including the development of RiotX, and the need to respond to competitive pressures or unanticipated working capital requirements. The Company may not be able to obtain additional debt or equity financing on favorable terms, if at all, which could impair our growth and adversely affect our existing operations. If the Company raises additional equity financing, the Company’s shareholders may experience significant dilution of their ownership interests, and the value per share of the Company’s common stock could decline. Furthermore, if the Company engages in additional debt financing, the holders of debt would have priority over the holders of common stock, and the Company may be required to accept terms that restrict its ability to incur additional indebtedness and take other actions that would otherwise possibly not be in the interests of the Company’s shareholders, forcing it to maintain specified liquidity or other ratios.

Accounting for Digital Currencies

The lack of U.S. Generally Accepted Accounting Principles (U.S. GAAP) instruction regarding the proper accounting treatment of digital currency assets has created uncertainty regarding the reporting and proper asset classification of digital currency holdings. Management has exercised its business judgment in determining appropriate accounting treatment for the recognition of revenue from mining of digital currencies. Management, in conjunction with its outside public accountants and its auditors, has examined various factors surrounding the substance of the Company’s operations and the available guidance in Accounting Standards Codification 606, Revenue from Contracts with Customers . Initially, the Company undertook to record its digital currency assets at fair market value on receipt and disposition. Based on subsequent reviews of the available accounting guidance, the Company has concluded that its originally adopted accounting policy was in error and that its digital currencies should have been recorded at cost less impairment. The Company has since revised its treatment of its digital currency assets in line with this corrected reevaluation. This change in accounting policy did not have a material impact of the Company’s previously reported condensed interim consolidated financial statements. Accordingly, the Company’s digital currency assets are included in its current assets on its consolidated balance sheets as intangible assets with indefinite useful lives recorded at cost less impairment. In the event authoritative guidance is enacted by the Financial Accounting Standards Board, the Company may be required to change its accounting policies which could result in a change to the Company’s financial statements.

Consequentially, the Company presently accounts for its digital currency assets as indefinite life intangible assets. An intangible asset with an indefinite useful life is not amortized, but rather is assessed for impairment annually, or more frequently, when events or changes in circumstances occur which indicate that it is more likely than not that the indefinite-lived asset is impaired. Impairment exists when the carrying amount exceeds its fair value. In testing for impairment, the Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted. Realized gain or loss on the sale of digital currencies is included in other income or expenses in the Company’s statements of operations.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision, you should consider carefully the risks, uncertainties and all risk factors set forth in the applicable prospectus supplement and the documents incorporated by reference in this prospectus, including the risk factors discussed under the heading “Risk Factors” in our most recent Annual Report on Form 10-K for the year ended December 31, 2017, as amended, and each subsequent filed quarterly report on Form 10-Q and current reports on Form 8-K, which may be amended, supplemented or superseded from time to time by the other reports we file with the SEC in the future.

In addition to those risk factors incorporated by reference herein, the Company has identified the following uncertainties and risk factors which may affect our business:

The price of our common stock may be influenced by the market price of digital currencies, among other factors, which may be susceptible to wide swings in value.

Digital currency market prices, in particular that of bitcoin, which represents our primary digital currency asset, have experienced significant short- and long-term fluctuations in value. There is no assurance that the price of digital currencies (i.e. bitcoin) may not have an adverse effect on the price of our common stock, despite management’s best efforts to pursue the Company’s core businesses. This is because the value and price of our common stock, as determined by the investing public, may be influenced by future anticipated adoption or appreciation in value of digital currencies or the blockchain generally, factors over which the Company has little or no influence or control. The Company’s share price may also be subject to pricing volatility due to supply and demand factors associated with few or limited public company options for investment in the digital currency industry.

Digital currency market prices are determined primarily using data from various exchanges, over-the-counter markets, and derivative platforms. Furthermore, such prices may be subject to factors such as those that impact commodities, more so than business activities, which could be subjected to additional influence from fraudulent or illegitimate actors, real or perceived scarcity, and political, economic, regulatory or other conditions. Pricing may be the result of, and may continue to result in, speculation regarding future appreciation in the value of digital currencies, or the Company or its share price, inflating and making their market prices more volatile or creating “bubble” type risks. As of the date of this prospectus, the trading price of bitcoin and other digital currencies has experienced significant decline and the trading price of our common stock has experienced a similar decline. If the trading price of the Company’s common stock declines below NASDAQ listing standards for an extended period our common stock could be suspended or delisted from the NASDAQ exchange.

In addition, as a result of the Company being an early participant in the blockchain and digital currency ecosystem, the Company’s common stock may be perceived as a way of maintaining investment exposure to the blockchain and digital currency markets without exposing the investor to the risk of a particular digital currency. As a result, the value of the Company’s common stock, and the value of digital currencies generally may be more likely to fluctuate due to changing investor confidence in future appreciation (or depreciation) in market prices, profits from related or unrelated investments or holdings of digital currency. Such factors or events associated with the volatility of digital currency markets may have a material adverse effect on the price of the Company common stock, which may in turn have a material adverse effect on the business, prospects or operations of the Company and potentially the value of any digital currency acquired by the Company.

Future sales and issuances of our equity securities or rights to purchase our equity securities would result in additional dilution of the percentage ownership of our stockholders.

Our stockholders may experience substantial dilution as we raise additional capital through issuances of equity securities. We may, from time to time, sell common stock, preferred stock, warrants, units, options or convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, preferred stock, warrants, units, options or convertible securities or other equity securities in more than one transaction, investors may be further diluted by subsequent sales. Management believes additional capital must be raised to continue executing the Company’s strategic plans. Management believes potential shareholder dilution resulting from the Company’s capital raising activities will be offset by increases in Company value and corresponding increases in the trading price of our common stock. Management cannot, however, guarantee that such sales will not result in material dilution to our existing stockholders, and further notes that new investors could gain rights superior to existing stockholders.

The price of our common stock could be adversely affected by subpoenas issued to the Company by the Securities and Exchange Commission pertaining to an ongoing investigation.

As previously disclosed, on April 9, 2018, the Company received a subpoena from the Securities and Exchange Commission (the “SEC”) in connection with an ongoing investigation. The Company has endeavored to fully cooperate with this ongoing investigation. The ultimate outcome of the investigation and its potential impact on the Company cannot be ascertained at this time. Regardless of the ultimate outcome, cooperation with the investigation has entailed, and may continue to entail, significant legal costs and the diversion of management’s attention away from the Company’s core businesses, which could have an impact on the trading prices of the Company’s common stock.

Further, as previously disclosed, the Company received a letter from the SEC (the “Letter”) on July 30, 2018 by the SEC that it had issued an Order Directing Examination and Designating Officers Pursuant to Section 8(e) of the Securities Act of 1933 with respect to the following registration statements: (i) a Form S-8 filed on July 19, 2017 (File No. 333-219357); (ii) a Form S-3 filed January 5, 2018, and amended February 7, 2018 (File No. 333-222450); and (iii) a Form S-3 filed on July 10, 2018 (File No. 333-226111). The Letter stated, “while the Section 8(e) examination is pending, the Division of Corporation Finance will not take any further action on the Registration Statements, and all communications with regard to the Registration Statements and the Section 8(e) examination should be made to the Commission’s Division of Enforcement.” The Company fully cooperated with the SEC’s examination and withdrew or terminated such registration statements on October 12, 2018. On October 22, 2018, the Company was notified by the SEC staff that the SEC had terminated the Section 8(e) examination with respect to the above-referenced registration statements. The previously disclosed SEC investigation associated with the subpoena received by the Company on April 9, 2018 is still ongoing, however, and the Company is continuing to cooperate in that investigation.

Currently, there is relatively small use of bitcoins in the retail and commercial marketplace in comparison to relatively large use by speculators, thus contributing to price volatility that could adversely affect an investment in the Company.

A significant portion of bitcoin demand is generated by speculators and investors seeking to profit from the short or long-term holding of bitcoins. A lack of expansion by bitcoins into retail and commercial markets, or alternative uses, may result in increased volatility or a reduction in the price of bitcoin, either of which could adversely impact the market price of digital currencies and may cause the trading price of our common stock to decline. Furthermore, no assurance can be made that, as markets for the exchange of digital currencies develop and mature, the inherent insubstantiality of stateless currency will not continue to contribute to the volatility of its conversion price to State-backed fiat currencies.

Banks and financial institutions may not provide banking services, or may cut off existing services, to businesses that provide digital currency related services or accept payment in the form of digital currencies, including financial institutions of investors in our securities.

The Company previously disclosed its agreement with SynapseFi and its banking partner , Evolve Bank and Trust, through the Company’s subsidiary, Logical Brokerage, on its periodic report on Form 8-K filed on October 29, 2018, in which SynapseFi and Evolve agreed to provide certain banking services to the Company’s planned digital currency exchange, RiotX.

A number of companies that provide digital currency related services have been unable to contract with banks or other similar financial institutions to provide such companies with banking services. Similarly, a number of companies and individuals associated with digital currencies and the provision of digital currency related services have had their existing banking services relationships terminated as a result of their association with digital currencies. Accordingly, the Company recognizes that its relationships with banking institutions could be subject to reconsideration and even termination, depending on their internal controls and practices vis-à-vis digital currencies.

Many businesses and individuals in the digital currencies field may experience difficulty in finding banking services which may have an adverse effect on the usefulness of digital currencies as a payment system, and further, that such lack of broad based acceptance may cause further harm to the public perception of digital currencies. These acceptance issues pervade the market for digital currencies and could act as an artificial deflationary pressure on the price of our digital currency assets and the overall trading price of our common stock.

The lack of broad base acceptance of digital currencies by banking institutions could result in increased compliance costs, risk of loss, and adverse governmental regulatory action of our activities such that out business operations and projections may be significantly adversely affected. This risk may also apply to underwriters, brokers, and ultimate holders of our securities, as our involvement in the digital currencies sector may be linked to our investors through our securities. Enforcement action by any governmental or quasi-governmental organization that prevents us from readily converting digital currencies into State-backed fiat currencies could have a material adverse effect on our Company.

If we are unable to attract major brokerage firms, we could have difficulty selling our common stock.

If we are unable to attract the interest of major brokerage firms through the value of our Company, we may be unable to secure their confidence and recommendation to purchase our common stock. The absence of such coverage may depress or otherwise slow the development of a robust market for our common stock, slowing our ability to raise capital.

Regulatory action against existing bitcoin and other digital currency exchanges may have a detrimental effect on the acceptance and widespread use of our planned digital currency exchange, RiotX.

In recent years, a number of bitcoin exchanges have been closed by governmental regulatory action due to alleged fraud and security breaches. Some investors were not compensated for the loss of their account balances on these exchanges. While our planned exchange is being developed to be licensed by the appropriate U.S. governmental and quasi-governmental regulatory authorities prior to launch, its planned scope will make it a desirable target for malware, DDoS, and other hacking attacks, which could lead to regulatory backlash against RiotX. RiotX is being developed to be resistant to such attacks, and to provide as much security and reliability to its future end users as possible, but such efforts may ultimately be ineffective due to the highly sophisticated and constantly evolving nature of cyber-attacks.

Additionally, international action against bitcoin exchanges has been harsh; China has moved to shut down all digital currency exchanges operating within its borders. Until such action was announced, mainland China and Hong Kong were responsible for a majority of global digital currency transactions. We believe such regulatory actions will be less common in the future as digital currencies continue to gain acceptance, however, such enforcement actions presently pose a risk to the value of our planned exchange, RiotX, and to the trading price of our common stock.

We may not have adequate recourse against third parties if our bitcoins and other digital currency assets are lost, stolen or destroyed.

The online nature of digital currencies such as bitcoins and their immutability poses a unique threat to their security. We have implemented robust security measures to minimize the exposure of our digital currencies to such risks including, without limitation, cold storage procedures to “air-gap” our digital currency keys from the internet. These measures are not perfect and improper access to and transfer of our digital current assets may still occur despite our security measures. By their nature, bitcoin transactions are largely irreversible. Our recourse in the event of theft or other loss is limited to our ability to secure restitution from the improper transferors or transferees of our digital currency assets. Recovery from such individuals may be limited by a number of factors including, without limitation, our ability to locate and identify both the transferors and transferees. This risk may pose a threat to the trading price of our common stock, and the occurrence of such an event could have a materially adverse effect on our business and operations.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the documents that we incorporate by reference, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Such forward-looking statements include those that express plans, anticipation, intent, contingency, goals, targets or future development and/or otherwise are not statements of historical fact. We believe these forward-looking statements are reasonable; however, you should not place undue reliance on any forward-looking statements, which are based on current expectations. These forward-looking statements are based on our current expectations and projections about future events and they are subject to risks and uncertainties known and unknown that could cause actual results and developments to differ materially from those expressed or implied in such statements.

In some cases, you can identify forward-looking statements by terminology, such as “expects,” “anticipates,” “intends,” “estimates,” “plans,” “believes,” “seeks,” “may,” “should,” “could” or the negative of such terms or other similar expressions. Accordingly, these statements involve estimates, assumptions and uncertainties that could cause actual results to differ materially from those expressed in them. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus. We intend for these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and we are including this statement for purposes of complying with these safe harbor provisions.

You should read this prospectus and the documents that we reference herein and therein and have filed as exhibits to the registration statement, of which this prospectus and any prospectus supplement is part, completely and with the understanding that our actual future results may be materially different from what we expect. You should assume that the information appearing in this prospectus is accurate as of the date on the front cover of this prospectus or such prospectus supplement only. Because the risk factors referred to above, as well as the risk factors incorporated herein by reference, could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf, you should not place undue reliance on any forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made, and 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, except as may be required under applicable law. New factors emerge from time to time, and it is not possible for us to predict which factors will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of the information presented in this prospectus and particularly our forward-looking statements, by these cautionary statements.

DESCRIPTION OF COMMON STOCK

General

We are authorized to issue 170,000,000 shares of common stock, at no par value per share.

Holders of the Company’s common stock are entitled to one vote for each share on all matters submitted to a stockholder vote. Holders of common stock do not have cumulative voting rights. Therefore, holders of a majority of the shares of common stock voting for the election of directors can elect all of the directors. Holders of the Company’s common stock representing a third of the voting power of the Company’s capital stock issued, outstanding and entitled to vote, represented in person or by proxy, are necessary to constitute a quorum at any meeting of stockholders. A vote by the holders of a majority of the Company’s outstanding shares is required to effectuate certain fundamental corporate changes such as liquidation, merger or an amendment to the Company’s certificate of incorporation.

Holders of the Company’s common stock are entitled to share in all dividends that the board of directors, in its discretion, declares from legally available funds. In the event of a liquidation, dissolution or winding up, each outstanding share entitles its holder to participate pro rata in all assets that remain after payment of liabilities and after providing for each class of stock, if any, having preference over the common stock. The Company’s common stock has no pre-emptive rights, no conversion rights and there are no redemption provisions applicable to the Company’s common stock.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Corporate Stock Transfer, Inc., Denver, Colorado.

Listing

DESCRIPTION OF PREFERRED STOCK

General

The Company’s articles of incorporation authorize the issuance of 15,000,000 shares of “blank check” preferred stock, no par value per share, in one or more series, subject to any limitations prescribed by law, without further vote or action by the stockholders. Each such series of preferred stock shall have such number of shares, designations, preferences, voting powers, qualifications, and special or relative rights or privileges as shall be determined by our board of directors, which may include, among others, dividend rights, voting rights, liquidation preferences, conversion rights and preemptive rights.

Preferred stock is available for possible future financings or acquisitions and for general corporate purposes without further authorization of stockholders unless such authorization is required by applicable law, the rules of the NASDAQ Capital Market or other securities exchange or market on which our stock is then listed or admitted to trading.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes could, under some circumstances, have the effect of delaying, deferring or preventing a change in control of the Company.

A prospectus supplement relating to any series of preferred stock being offered will include specific terms relating to the offering. Such prospectus supplement will include:

the title and stated or par value of the preferred stock;

the number of shares of the preferred stock offered, the liquidation preference per share and the offering price of the preferred stock;

the dividend rate(s), period(s) and/or payment date(s) or method(s) of calculation thereof applicable to the preferred stock;

whether dividends shall be cumulative or non-cumulative and, if cumulative, the date from which dividends on the preferred stock shall accumulate;

the provisions for a sinking fund, if any, for the preferred stock;

any voting rights of the preferred stock;

the provisions for redemption, if applicable, of the preferred stock;

any listing of the preferred stock on any securities exchange;

the terms and conditions, if applicable, upon which the preferred stock will be convertible into our common stock, including the conversion price or the manner of calculating the conversion price and conversion period;

if appropriate, a discussion of Federal income tax consequences applicable to the preferred stock;

and any other specific terms, preferences, rights, limitations or restrictions of the preferred stock.

The terms, if any, on which the preferred stock may be convertible into or exchangeable for our common stock will also be stated in the preferred stock prospectus supplement. The terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option, and may include provisions pursuant to which the number of shares of our common stock to be received by the holders of preferred stock would be subject to adjustment.

Series B Preferred Stock

We have designated 1,750,001 shares of preferred stock as “0% Series B Convertible Preferred Stock.” The shares of Series B Preferred Stock are convertible into shares of common stock based on a conversion calculation equal to the stated value of the Series B Preferred Stock, plus all accrued and unpaid dividends, if any, on such Series B Preferred Stock, as of such date of determination, divided by the conversion price. The stated value of each share of Series B Preferred Stock is $6.80 and the initial conversion price is $6.80 per share, each subject to adjustment for stock splits, stock dividends, recapitalizations, combinations, subdivisions or other similar events.

The holders of Series B Preferred Stock are entitled to receive dividends if and when declared by our board of directors. The Series B Preferred Stock will participate on an “as converted” basis, with all dividends declared on the Company's common stock. Such dividends will be paid by the Company out of funds legally available therefor, payable, subject to the conditions and other terms hereof, in cash on the stated value of such Series B Preferred Stock.

We are prohibited from effecting a conversion of the Series B Preferred Stock to the extent that, as a result of such conversion, the holder would beneficially own more than 4.99% percent of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock upon conversion of the Series B Preferred Stock, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99% percent. The Series B Preferred Stock contain no voting rights.

The Series B Preferred Stock contains a blocker pursuant to which, if we have not obtained the approval of our shareholders in accordance with NASDAQ Listing Rule 5635(d), then we may not issue upon conversion of the Series B Preferred Stock a number of shares of common stock, which, when aggregated with any other shares of common stock underlying the Series B Preferred Stock would exceed 19.99% of the shares of common stock issued and outstanding as of the date of exchange agreement between the Company and the holders of the Series B Preferred Stock, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the common stock.

As of the date of this prospectus, there are 13,000 shares of Series B Convertible Preferred Stock outstanding, convertible into 13,000 shares of common stock which represents less than 1% of the shares of our common stock as of the date of this prospectus.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of preferred stock or common stock. Warrants may be issued independently or together with any preferred stock or common stock, and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between a warrant agent specified in the agreement and us. The warrant agent will act solely as our agent in connection with the warrants of that series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. This summary of some provisions of the securities warrants is not complete. You should refer to the securities warrant agreement, including the forms of securities warrant certificate representing the securities warrants, relating to the specific securities warrants being offered for the complete terms of the securities warrant agreement and the securities warrants. The securities warrant agreement, together with the terms of the securities warrant certificate and securities warrants, will be filed with the Securities and Exchange Commission in connection with the offering of the specific warrants.

The applicable prospectus supplement will describe the following terms, where applicable, of the warrants in respect of which this prospectus is being delivered:

Prior to the exercise of any securities warrants to purchase preferred stock or common stock, holders of the warrants will not have any of the rights of holders of the common stock or preferred stock purchasable upon exercise, including in the case of securities warrants for the purchase of common stock or preferred stock, the right to vote or to receive any payments of dividends on the preferred stock or common stock purchasable upon exercise.

The prospectus supplement will include the following information:

Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.

Sale through Underwriters or Dealers

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

Direct Sales and Sales through Agents

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

Delayed Delivery Contracts

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Continuous Offering Program

Without limiting the generality of the foregoing, we may enter into a continuous offering program equity distribution agreement with a broker-dealer, under which we may offer and sell shares of our common stock from time to time through a broker-dealer as our sales agent. If we enter into such a program, sales of the shares of common stock, if any, will be made by means of ordinary brokers’ transactions on the NASDAQ Capital Market at market prices, block transactions and such other transactions as agreed upon by us and the broker-dealer. Under the terms of such a program, we also may sell shares of common stock to the broker-dealer, as principal for its own account at a price agreed upon at the time of sale. If we sell shares of common stock to such broker-dealer as principal, we will enter into a separate agreement with such broker-dealer, and we will describe this agreement in a separate prospectus supplement or pricing supplement.

Market Making, Stabilization and Other Transactions

Unless the applicable prospectus supplement states otherwise, other than our common stock all securities we offer under this prospectus will be a new issue and will have no established trading market. We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

LEGAL MATTERS

The validity of the issuance of the securities offered by this prospectus will be passed upon for us by Dickinson Wright PLLC, Reno, Nevada. If certain legal matters in connection with an offering of the securities covered by this prospectus and a related prospectus supplement are passed upon by counsel for the underwriters, if any, of such offering, that counsel will be named in the related prospectus supplement for such offering.

Item 15. Indemnification of Directors and Officers.

Nevada Revised Statutes Sections 78.7502 and 78.751 provide us with the power to indemnify any of our directors and officers. The director or officer must have conducted himself/herself in good faith and reasonably believe that his/her conduct was in, or not opposed to, our best interests. In a criminal action, the director, officer, employee or agent must not have had reasonable cause to believe his/her conduct was unlawful.

Under Nevada Revised Statutes Section 78.751, advances for expenses may be made by agreement if the director or officer affirms in writing that he/she believes he/she has met the standards and will personally repay the expenses if it is determined such officer or director did not meet the standards.

Our Articles of Incorporation provide that our officers and directors shall be indemnified and held harmless to the fullest extent legally permissible under the laws of the State of Nevada against all expenses, liability and loss (including attorneys' fees, judgments, fines and amounts paid or to be paid in settlement) reasonably incurred or suffered by them in connection with any civil, criminal, administrative or investigative action, suit or proceeding related to their service as an officer or director. Such right of indemnification shall be a contract right which may be enforced in any manner desired by such person. We must pay the expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by us. Such right of indemnification shall not be exclusive of any other right which such directors or officers may have or hereafter acquire.

Our Articles of Incorporation provide that we may adopt bylaws to provide at all times the fullest indemnification permitted by the laws of the State of Nevada, and may purchase and maintain insurance on behalf of any of officers and directors. The indemnification provided in our Articles of Incorporation shall continue as to a person who has ceased to be a director, officer, employee or agent, and shall inure to the benefit of the heirs, executors and administrators of such person.

Our Bylaws provide that a director or officer shall have no personal liability to us or our stockholders for damages for breach of fiduciary duty as a director or officer, except for damages for breach of fiduciary duty resulting from (a) acts or omissions which involve intentional misconduct, fraud, or a knowing violation of law, or (b) the payment of dividends in violation of Nevada Revised Statutes Section 78.300.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1)

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

(i)

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

(ii)

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

provided, however , Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

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

II-2

(3)

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

(4)

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

(i)

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

(ii)

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

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, 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.

(b)

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

II-3

(c)

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

(d)

The 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 such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-4
