EXPLANATORY NOTE

Post-Effective Amendment No. 2 to the Registration Statement on Form S-3 (File No. 333-290950) of Solana Company (the “Registrant”) was filed because the Registrant expected that it would no longer be a “well-known seasoned issuer” (as such term is defined in Rule 405 of the Securities Act of 1933, as amended (the “Securities Act”)) when it filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2025. This Post-Effective Amendment No. 3 is being filed using EDGAR submission type POS AM in order to convert the Registration Statement to the proper EDGAR submission type for a non-automatic shelf registration statement and makes certain other amendments.

The Registrant previously registered an aggregate of 155,646,217 shares of Class A common stock pursuant to the Registration Statement for resale by the selling stockholders identified herein (including 369,720 shares of Class A common stock registered in the Post-Effective Amendment No. 1 to the Registration Statement filed with the Securities and Exchange Commission on November 17, 2025 (the “November POSASR”), which became effective immediately upon filing). Certain information regarding the securities being offered pursuant to the accompanying prospectus contained herein was dated as of November 13, 2025 and November 14, 2025, which were the measurement dates used in the November POSAR.

No additional securities are being registered under this Post-Effective Amendment No. 3 to the Registration Statement. All applicable registration fees were paid at the time of the initial filing of the Registration Statement and the November POSAR.

The information in this preliminary prospectus is not complete and may be changed. We may not sell these securities until the U.S. Securities and Exchange Commission declares our registration statement effective. This preliminary prospectus is not an offer to sell these securities and we are not soliciting offers to buy these securities in any state or jurisdiction where the offer or sale is not permitted.

TABLE OF CONTENTS

PROSPECTUS SUMMARY

This summary does not contain all of the information that you should consider before investing in our Common Stock offered by this prospectus. Before making an investment decision, you should carefully read the entire prospectus, including the “Risk Factors” section beginning on page 4 of this prospectus and in our most recent Annual Report on Form 10-K and our subsequent Quarterly Reports on Form 10-Q, as well as in the other reports we file with the SEC, as well as our financial statements, including the accompanying notes, and the other information incorporated by reference herein and the information in any related free writing prospectus that we may authorize for use in connection with this offering of our Common Stock.

Overview

We are a listed digital asset treasury (“DAT”) dedicated to acquiring and holding Solana tokens (“SOL”). Solana Company’s DAT objective is to maximize SOL per share through strategic use of capital markets and onchain opportunities, offering public market investors direct exposure to Solana’s secular growth.

Strategic digital asset reserves like SOL lay the groundwork for a future where global payments, credentialing, and personalized learning can be powered by decentralized infrastructure, enhancing how we grow our company. We believe that Solana represents a uniquely scalable, high-performance blockchain platform that aligns with our long-term vision of integrating innovative technologies into our services. By investing in and participating in the Solana ecosystem, we aim to both enhance our digital asset treasury strategy and create strategic optionality for product innovation in our core business.

We are also, to a lesser extent, a neurotechnology company focused on neurological wellness.

Digital Asset Treasury

In September 2025, we adopted a digital asset treasury strategy centered on acquiring SOL and began repositioning a substantial portion of our balance sheet around that strategy. We expect the digital asset treasury strategy to be our principal strategic focus. Our assets are expected to remain concentrated primarily in SOL. Our objective is to increase long-term shareholder value by increasing the amount of SOL underlying each share, generating yield on treasury assets where appropriate, and using public-market financing and treasury tools in a disciplined manner to compound net asset value (“NAV”) over time.

Unlocked and Locked SOL

We hold SOL, which consist of both unrestricted tokens (“Unlocked SOL”), which unless qualified otherwise, Unlocked SOL shall only refer to unrestricted SOL tokens that are readily transferrable onchain on the Solana network or staked SOL subject to the normal unbonding period, and restricted tokens subject to contractual lock-up (“Locked SOL”). Locked SOL tokens held in custodial controlled omnibus or segregated custodial accounts are subject to contractual and onchain restrictions (“Smart Contracts”) that limit our ability to withdraw, transfer, or otherwise direct the use of the tokens until specified unlock conditions are met. The Locked SOL are subject to relatively even monthly unlocks through January 2028. We continue to benefit from staking rewards earned on Locked SOL.

Recent Developments

Solana-centric Digital Asset Treasury Strategy and Private Placements

On September 15, 2025, we entered into securities purchase agreements (the “Cash Securities Purchase Agreements”) with certain accredited investors (the “Cash Purchasers”) pursuant to which we agreed to sell and issue to the Cash Purchasers in a private placement offering (the “Cash Offering”) an aggregate offering of (i) either shares (the “Cash Shares”) of Common Stock at an offering price of $6.881 per Cash Share (the “Per Share Cash Purchase Price”); and/or pre-funded warrants (the “Cash Pre-Funded Warrants”) to purchase shares of the Common Stock (the “Cash Pre-Funded Warrant Shares”) at an offering price of the Per Share Cash Purchase Price less $0.001 per Cash Pre-Funded Warrant, and (ii) stapled warrants (the “Cash Stapled Warrants” and, together with the Cash Shares and the Cash Pre-Funded Warrants, the

TABLE OF CONTENTS

“Cash Securities”) to purchase shares of the Common Stock (the “Cash Stapled Warrant Shares”) at an exercise price of $10.134 per Cash Stapled Warrant. In the Cash Offering, the Cash Purchasers tendered any of U.S. dollars, USDC or USDT (or a combination thereof) to the Company as consideration for the Cash Shares, Cash Stapled Warrants and Cash Pre-Funded Warrants.

On September 15, 2025, we also entered into securities purchase agreements (the “Cryptocurrency Securities Purchase Agreements,” and together with the Cash Securities Purchase Agreements, the “Securities Purchase Agreements”) with certain accredited investors (the “Cryptocurrency Purchasers,” and together with the Cash Purchasers, the “Purchasers”) pursuant to which the Company agreed to sell and issue to the Cryptocurrency Purchasers in a private placement (the “Cryptocurrency Offering,” and together with the Cash Offering, the “PIPE Offerings”) (i) pre-funded warrants (“Cryptocurrency Pre-Funded Warrants” and, together with the Cash Pre-Funded Warrants, the “Pre-Funded Warrants”) to purchase shares of Common Stock (“Cryptocurrency Pre-Funded Warrant Shares” and, together with the Cash Pre-Funded Warrant Shares, the “Pre-Funded Warrant Shares”) at an offering price of $6.881 less $0.001 and (ii) stapled warrants (the “Cryptocurrency Stapled Warrants,” and together with the Cash Stapled Warrants, the “Stapled Warrants”) to purchase shares of Common Stock (the “Cryptocurrency Stapled Warrant Shares,” and together with the Cash Stapled Warrant Shares, the “Stapled Warrant Shares”) at an exercise price of $10.134 per Cryptocurrency Stapled Warrant. In the Cryptocurrency Offering, the Cryptocurrency Purchasers tendered either Unlocked SOL tokens or Locked SOL tokens to the Company as consideration for the Cryptocurrency Pre-Funded Warrants and the Cryptocurrency Stapled Warrants.

The exercise of the Cryptocurrency Pre-Funded Warrants and Cryptocurrency Stapled Warrants into Cryptocurrency Pre-Funded Warrant Shares and Cryptocurrency Stapled Warrant Shares, respectively, is subject to stockholder approval (“Stockholder Approval”) and such warrants will not be exercisable for Common Stock until such Stockholder The Company held a special meeting of stockholders to obtain Stockholder Approval on October 30, 2025.

We received aggregate gross proceeds of approximately $500 million from the PIPE Offerings, before deducting placement agent fees and other offering expenses. The PIPE Offerings closed on September 18, 2025. We intend to use the net proceeds from the PIPE Offerings to fund the acquisition of SOL, the native cryptocurrency of the Solana Foundation blockchain, through open market purchases only and the establishment of the Company’s Solana treasury operations, as well as for working capital, general corporate purposes and to pay all transaction fees and expenses related thereto. In connection with the announcement of the PIPE Offerings, we announced the launch of our digital asset treasury strategy, pursuant to which we plan to pursue a number of strategic initiatives to acquire Solana and other digital assets.

ATM Program

On September 15, 2025, the Company entered into a Sales Agreement (the “Sales Agreement”) with Clear Street LLC and Maxim Group LLC (each, an “Agent,” and, together, the “Agents”), as co-sales agents, pursuant to which the Company may offer and sell shares of Common Stock from time to time having an aggregate sales price of up to $92.8 million (the “ATM Program”).

Upon delivery of a placement notice, and subject to the terms and conditions of the Sales Agreement, the Agents may sell the Shares by any method that is deemed an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or any other method permitted by law, which may include negotiated transactions or block trades. The Company may sell the shares of Common Stock through the Agents in amounts and at times to be determined by the Company from time to time subject to the terms and conditions of the Sales Agreement, but neither it nor the Agents have an obligation to sell any of the shares of Common Stock in the ATM Program. No assurance can be given that the Company will sell any shares of Common Stock under the Sales Agreement, or, if it does, as to the price or the amount of shares of Common Stock that it sells or the dates when such sales will take place. The Company or the Agents may suspend or terminate the ATM Program upon notice to the other parties and subject to other conditions. The Agents will use commercially reasonable efforts basis to effect the sales consistent with normal trading and sales practices.

The Company has agreed to pay the Agents’ commissions for their respective services in acting as agents in the sale of the shares of Common Stock in the amount of up to 3.00% of the aggregate gross

TABLE OF CONTENTS

proceeds it receives from each sale of its shares of Common Stock pursuant to the Sales Agreement. The Company has also agreed to provide the Agents with customary indemnification and contribution rights. In addition, the Company has agreed to reimburse certain legal expenses incurred by the Agent in connection with execution of the Sales Agreement in an amount up to $75,000, in addition to certain ongoing legal expenses.

Portable Neuromodulation Stimulator

In addition to being a Solana-centric digital asset treasury company, we are a neurotechnology company focused on neurological wellness. Our purpose is to develop, license or acquire non-implantable technologies targeted at reducing symptoms of neurological disease or trauma, and integrating blockchain technology allows us to build a more secure, scalable, and efficient platform.

Strategic digital asset reserves like SOL lay the groundwork for a future where global payments, credentialing, and personalized learning can be powered by decentralized infrastructure, enhancing how we grow our company. We believe that Solana represents a uniquely scalable, high-performance blockchain platform that aligns with our long-term vision of integrating innovative technologies into our services. By investing in and participating in the Solana ecosystem, we aim to both enhance our treasury strategy and create strategic optionality for product innovation in our core business.

Our product, known as the Portable Neuromodulation Stimulator, or PoNS®, is an innovative non-implantable medical device, inclusive of a controller and mouthpiece, which delivers mild electrical stimulation to the surface of the tongue to provide treatment of gait deficit and chronic balance deficit. PoNS Therapy® is integral to the overall PoNS solution and is the physical therapy applied by patients during use of the PoNS device. PoNS has marketing clearance in the U.S. for use as a short-term treatment of gait deficit due to mild-to-moderate symptoms for multiple sclerosis (“MS”) and is to be used as an adjunct to a supervised therapeutic exercise program in patients 22 years of age and over by prescription only. We began accepting prescriptions for PoNS in the U.S. in March 2022, and commercial sales of PoNS commenced in April 2022. PoNS is authorized for sale in Canada for three indications: (i) as a short term treatment (14 weeks) of chronic balance deficit due to mild-to-moderate traumatic brain injury and is to be used in conjunction with physical therapy; (ii) as a short term treatment (14 weeks) of gait deficit due to mild and moderate symptoms from MS and it is to be used in conjunction with physical therapy; and (iii) as a short term treatment (14 weeks) of gait deficit due to mild and moderate symptoms from stroke, to be used in conjunction with physical therapy. It has been commercially available in Canada since March 2019. PoNS is authorized for sale as a Class II a medical device in Australia and we have been seeking a business partner to commercialize and distribute PoNS in Australia.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks and uncertainties described under “Risk Factors” in our most recent annual report on Form 10-K as supplemented or updated in our most recent quarterly report on Form 10-Q, any current report on Form 8-K, as well as any accompanying prospectus supplement, together with all of the other information included or incorporated by reference in this prospectus and in any accompanying prospectus supplement, including our financial statements and related notes, before deciding whether to purchase our securities. See “Where You Can Find More Information; Incorporation of Certain Information by Reference.”

Our business, financial condition and results of operations could be materially and adversely affected by any or all of these risks or by additional risks and uncertainties not presently known to us or that we currently deem immaterial that may adversely affect us in the future. The Company is supplementing the risk factors previously disclosed in its Annual Report on Form 10-K for the year ended December 31, 2024 (the “Form 10-K”), subsequent Quarterly Reports on Form 10-Qs (the “Form 10-Qs”) and the Prospectus Supplement filed with the SEC on September 15, 2025 with the following risk factors. These risk factors should be read in conjunction with the risk factors included in the Form 10-K, the Form 10-Qs and the Prospectus Supplement filed with the SEC on September 15, 2025.

Risks Related to This Offering and Our Common Stock

The price of our Common Stock has and may continue to fluctuate significantly, and this may make it difficult for you to resell shares of Common Stock owned by you at times or at prices you find attractive.

The trading price of our Common Stock has fluctuated widely and may continue to fluctuate widely as a result of a number of factors, many of which are outside our control. This volatility may affect the price at which you could sell the shares of our Common Stock, and the sale of substantial amounts of our Common Stock could adversely affect the price of our Common Stock. Our stock price is likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors.

As a result, you may not be able to sell your shares of Common Stock at or above the price at which you purchase them. In addition, the stock market in general, and Nasdaq and the stock of digital asset and blockchain technology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our Common Stock, regardless of our actual operating performance.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future, through our ATM Program or other means, offer additional shares of our Common Stock or other securities convertible into or exchangeable for our Common Stock at prices that may not be the same as the price per share of our Common Stock in this offering. We may sell through our ATM Program or other means, additional shares of our Common Stock or other securities in any other offering at a price per share that is less than the price per share paid by the Selling Stockholders, and investors purchasing shares of our Common Stock or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our Common Stock, or securities convertible into or exchangeable for our Common Stock, in future transactions may be higher or lower than the price per share paid by investors in this offering. Moreover, to the extent that we issue options or warrants to purchase, or securities convertible into or exchangeable for, our shares of Common Stock in the future and those options, warrants or other securities are exercised, converted or exchanged, stockholders may experience future dilution.

In addition, the sale of shares our Common Stock in this offering and any future sales of a substantial number of shares of our Common Stock in the public market, or the perception that such sales may occur, could adversely affect the price of our Common Stock. We cannot predict the effect, if any, that market sales of those shares of our Common Stock, or the perception that those shares may be sold, will have on the market price of our Common Stock.

TABLE OF CONTENTS

Sales of our common stock in our ATM Program, or the perception that such sales may occur, could cause the market price of our common stock to fall.

On September 15, 2025, we entered into a Sales Agreement with Clear Street LLC and Maxim Group LLC pursuant to which we may offer and sell the ATM Shares from time to time. Continued sales of our Common Stock, if any, under the ATM Program will depend upon market conditions and other factors to be determined by us and may be made in negotiated transactions or transactions that are deemed to be “at the market offerings” as defined in Rule 415 under the Securities Act. Future sales of our Common Stock are not guaranteed, and there are no firm commitments to receive funding under the ATM Program. The issuance from time to time of these new shares of Common Stock, or the perception that such sales may occur, could have the effect of depressing the market price of our Common Stock.

The sale or availability for sale of a substantial number of shares of our Common Stock could adversely affect the market price of such shares.

Sales of a substantial number of shares of our Common Stock in the public market, or the perception or indication that these sales could occur, could adversely affect the market price of such shares and could materially impair our ability to raise capital through equity offerings in the future or cause the trading price of our Common Stock to decline. We are unable to predict what effect, if any, sales of securities in this offering or by our significant stockholders, directors or officers will have on the market price of our Common Stock.

Market price of our Common Stock may be volatile, which could subject us to securities class action litigation and result in substantial losses for our stockholders.

The market price of shares of our Common Stock could be subject to wide fluctuations in response to many risk factors listed in this section and the documents incorporated by reference in this prospectus as well as other factors others beyond our control. Furthermore, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations as well as general economic, political and market conditions, such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of shares of our Common Stock. In addition, such fluctuations could subject us to securities class action litigation, which could result in substantial costs and divert our management’s attention from other business concerns, which could potentially harm our business. As a result of this volatility, our stockholders may not be able to sell their shares of our Common Stock at or above the price at which they purchased their shares of our Common Stock.

If securities analysts do not publish research or reports about our business or if they publish negative, or inaccurate, evaluations of our Common Stock, the price of our stock and trading volume could decline.

The trading market for our Common Stock may be impacted, in part, by the research and reports that securities or industry analysts publish about us or our business. There can be no assurance that analysts will cover us, continue to cover us or provide favorable coverage. If one or more analysts downgrade our Common Stock or change their opinion of our Common Stock, our share price may decline. In addition, if one or more analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Resales of our Common Stock in the public market by our stockholders (including the Selling Stockholders) may cause the market price of our shares of Common Stock to fall.

Sales of a substantial number of shares of Common Stock could occur at any time, including sales by the Selling Stockholders under this prospectus. The issuance of new shares of Common Stock could result in resales of our shares of Common Stock by our current stockholders concerned about the potential ownership dilution of their holdings. In turn, these resales could have the effect of depressing the market price for our shares of Common Stock.

All of the shares of Common Stock being offered hereby are being sold by Selling Stockholders. The Selling Stockholders listed under the heading “Selling Stockholders” in this prospectus or any applicable prospectus supplement will receive all of the net proceeds from the sales of shares of Common Stock.

We are registering the resale of such Securities in order to permit such Selling Stockholders to offer the Securities for resale from time to time. The Advisor Shares were issued pursuant to Section 4(a)(2) of the Securities Act on September 18, 2025.

We may register additional shares for resale for the account of additional Selling Stockholders in the future through an accompanying prospectus supplement.

We are registering the resale of the shares of Common Stock held by the Selling Stockholders to permit the Selling Stockholders to resell or otherwise dispose of such shares in the manner contemplated under “Plan of Distribution” in this prospectus and any accompanying prospectus supplement. As used in this prospectus, the term “selling stockholders” includes the selling securityholder listed in the table below, and the pledgees, donees, transferees, assignees, successors, designees, successors-in-interest and others who later come to hold any of the Selling Stockholder’s interest in such shares other than through a public sale.

The Selling Stockholders may sell some, all or none of the shares of Common Stock held by them. We do not know how long the Selling Stockholders will hold such shares before selling them, and we currently have no agreements, arrangements or understandings with the Selling Stockholders regarding the sale or other disposition of any of their shares of Common Stock. The shares of Common Stock covered hereby may be offered from time to time by the Selling Stockholders.

The following table sets forth the number of shares of our outstanding Common Stock beneficially owned by the Selling Stockholders as of November 14, 2025, the number of shares of Common Stock that may be offered under this prospectus, and the number of shares and percentage of our outstanding Common Stock beneficially owned by the Selling Stockholders assuming all of the shares of Common Stock covered hereby are sold. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to our shares of Common Stock. Generally, a person “beneficially owns” shares of Common Stock if the person has or shares with others the right to vote those shares or to dispose of them, or if the person has the right to acquire voting or disposition rights within 60 days. The number of shares in the column “Number of Shares of Common Stock Registered for Sale Hereby” represents all of the shares of Common Stock that the Selling Stockholders may offer and sell from time to time under this prospectus.

All information contained in the table below and the footnotes thereto is based upon information provided to us by the Selling Stockholders as of the date of the November POSASR. The Selling Stockholders may have sold or transferred, in transactions exempt from the registration requirements of the Securities Act, some or all of their shares or other securities since the date on which the information in the table below is presented.

The percentage of shares owned after the offering is based on 41,446,727 shares of our Common Stock outstanding as of November 13, 2025 (figure assumes all of the Warrants were exercised).

Relationships with the Selling Stockholders

The Selling Stockholders have not had any material relationships with our officers, directors, or affiliates over the past three years, except (i) for the ownership of the shares, (ii) as described in the section of this prospectus titled “Prospectus Summary — Recent Developments,” and (iii) as described in this section and in the table and footnotes above.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

The shares of Common Stock owned by the Selling Stockholders covered by this prospectus and any applicable prospectus supplement may be offered, sold, transferred or otherwise disposed of from time to time by such Selling Stockholders. The Selling Stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges, markets, trading facilities or in the over-the-counter market or otherwise, at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale or at negotiated prices. The Selling Stockholders may sell or otherwise dispose of their securities by one or more of, or a combination of, the following methods:

•

through one or more underwriters in a public offering, pursuant to which underwriters may resell the shares in one or more transactions, including in negotiated transactions at a fixed public offering price or at varying prices determined at the time of sale;

•

purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

•

ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•

transactions in which the broker-dealer solicits purchasers on a best efforts basis;

•

block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

an over-the-counter distribution in accordance with the rules of the Nasdaq Stock Market;

•

through trading plans entered into by a Selling Stockholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement that provide for periodic sales of its securities on the basis of parameters described in such trading plans;

•

short sales or through the settlement of short sales (including short sales “against the box”), subject to compliance with the Securities Act and other applicable securities laws;

•

distribution to employees, members, limited partners or stockholders of a Selling Stockholder;

•

through the writing or settlement of standardized or over-the-counter options, swaps or other hedging or derivative transactions, whether through an options exchange or otherwise;

•

in other ways not involving market makers or established trading markets, including direct sales to purchasers or sales effected through agents;

•

by pledge of securities for any loan or obligation (including obligations associated with derivative transactions), including pledges to brokers or dealers who may from time to time effect distributions of securities, and in the case of any collateral call or default on such loan or obligation, pledges or sales of securities by such pledgee or secured parties;

•

delayed delivery arrangements providing for payment and delivery on a specified date in the future;

•

in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

•

in privately negotiated transactions;

•

through dividends or other distributions made by a Selling Stockholder to its partners, members or stockholders;

•

in options transactions;

•

through a combination of any of the above methods of sale; or

•

any other method permitted pursuant to applicable law.

TABLE OF CONTENTS

In addition, any securities that qualify for sale pursuant to Rule 144 or another exemption from registration under the Securities Act or other such exemption may be sold under Rule 144 rather than pursuant to this prospectus or any accompanying prospectus supplement. Further, the Selling Stockholders may enter into derivative transactions with broker-dealers, other financial institutions or third parties or sell securities not covered by this prospectus or any accompanying prospectus supplement to third parties in privately negotiated or registered transactions. These transactions may involve the sale of shares of Common Stock by the Selling Stockholders by forward sale or by an offering (directly or by entering into derivative transactions with broker-dealers, other financial institutions or third parties) of options, swaps, rights, warrants or other securities that are offered with, convertible into or exchangeable for shares of Common Stock.

The Selling Stockholders may elect to make an in-kind distribution of the shares of Common Stock to its members, partners or shareholders. In such event, we may file a prospectus supplement to the extent required by law in order to permit the distributees to use the prospectus to resell the shares of Common Stock acquired in the distribution.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the securities or otherwise, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of the securities in the course of hedging the positions they assume with a selling the stockholder. The Selling Stockholders may also sell the securities short and redeliver the securities to close out such short positions. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions 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 may also pledge securities to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of the pledged securities pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In effecting sales, broker-dealers or agents engaged by the Selling Stockholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Stockholders in amounts to be negotiated immediately prior to the sale.

In offering the securities covered by this prospectus and any applicable prospectus supplement, the Selling Stockholders and any broker-dealers who execute sales for the Selling Stockholders may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. Any profits realized by the Selling Stockholders and the compensation of any broker-dealer may be deemed to be underwriting discounts and commissions.

If at the time of any offering made under this prospectus a member of FINRA participating in the offering has a “conflict of interest” as defined in FINRA Rule 5121, or Rule 5121, that offering will be conducted in accordance with the relevant provisions of Rule 5121.

In order to comply with the securities laws of certain states, if applicable, the Securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the Securities 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.

The Selling Stockholders and any other persons participating in the distribution will be subject to the applicable provisions of the Exchange Act and the rules and regulations under the Exchange Act, including, without limitation, Regulation M, which may limit the timing of purchases and sales by the Selling Stockholders and any other relevant persons of any of the securities. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of securities to engage in market-making activities with respect to the securities being distributed. All of the above may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.

In addition, we will make copies of this prospectus and any applicable prospectus supplement available to the Selling Stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities

Act. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the securities against certain liabilities, including liabilities arising under the Securities Act.

At the time a particular offer of securities is made, if required, a prospectus supplement will be distributed that will set forth the number of securities being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

We have agreed to indemnify the Selling Stockholders against certain liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares of Common Stock offered by this prospectus.

Item 15. Indemnification of Directors and Officers.

We are incorporated under the laws of the State of Delaware. Section 102 of the Delaware General Corporation Law permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director or officer, except where the director or officer breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.

Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he or she is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

As permitted by the Delaware General Corporation Law, our amended and restated bylaws provide that: (1) we are required to indemnify our directors and executive officers to the fullest extent permitted by the Delaware General Corporation Law; (2) we may, in our discretion, indemnify our other officers, employees and agents as set forth in the Delaware General Corporation Law; (3) we are required, upon satisfaction of certain conditions, to advance all expenses incurred by our directors and executive officers in connection with certain legal proceedings; (4) the rights conferred in the bylaws are not exclusive; (5) we are authorized to enter into indemnification agreements with our directors, officers, employees and agents; and (6) we may secure insurance on behalf of any director, officer, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law.

TABLE OF CONTENTS

Indemnification Agreements

We have entered into indemnification agreements with our directors and officers. These agreements provide broader indemnity rights than those provided under the Delaware General Corporation Law and the Registrant’s certificate of incorporation, as amended. The indemnification agreements are not intended to deny or otherwise limit third-party or derivative suits against us or our directors or officers, but to the extent a director or officer were entitled to indemnity or contribution under the indemnification agreement, the financial burden of a third-party suit would be borne by us, and we would not benefit from derivative recoveries against the director or officer. Such recoveries would accrue to our benefit but would be offset by our obligations to the director or officer under the indemnification agreement.

Insurance Policy

We maintain a directors’ and officers’ liability insurance policy. The policy insures directors and officers against unindemnified losses arising from certain wrongful acts in their capacities as directors and officers and reimburses us for those losses for which we have lawfully indemnified the directors and officers. The policy contains various exclusions.

The foregoing summaries are not intended to be exhaustive and are qualified in their entirety by reference to the complete text of the statute, the Registrant’s certificate of incorporation, as amended and the agreements referred to above and are qualified in their entirety by reference thereto.

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;

(ii)

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

TABLE OF CONTENTS

(iii)

to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act 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, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

(4) That, for the purpose of determining liability under the Securities Act 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 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 the 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.

(b) The undersigned registrant undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) 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.

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