EXPLANATORY NOTE

On April 4, 2018, Superconductor Technologies Inc. (the “Company”) filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (File No. 333-224148) (the “April Registration Statement” or the “April Form S-1”). The April Registration Statement was declared effective by the Commission on April 10, 2018. On July 2, 2018, the Company filed with the Commission a registration statement on Form S-1 (File No. 333-226025) (the “July Registration Statement” or the “July Form S-1”), which was amended by a pre-effective amendment filed on July 24, 2018 and post-effective amendment filed on July 27, 2018. The July Registration Statement was declared effective by the Commission on July 25, 2018. The April Form S-1 and the July Form S-1 are collectively referred to as the “Original Registration Statements.”

The April Form S-1 registered the offer and sale by the selling stockholder named herein of 158,100 shares of common stock underlying warrants to purchase shares of the Company’s common stock by certain selling stockholders described in the prospectus, or their transferees (as adjusted for a subsequent reverse stock split). These warrants were issued in connection with a private placement that closed on March 9, 2018.

The July Form S-1 included registering the offer and sale by the Company of an aggregate of 2,725,715 shares of common stock underlying warrants to purchase shares of the Company’s common stock issued (and consisting of 2,571,429 shares of common stock underlying warrants acquired by investors and 154,286 shares of common stock underlying warrants issued to the placement agent in such transaction. These warrants were issued in connection with a public offering that closed on July 30, 2018.

This Post-Effective Amendment No. 1 to Form S-1 on Form S-3 (this “Post-Effective Amendment”) is being filed to convert the Original Registration Statements to a registration statement on Form S-3 and to continue the existing registration of up to 2,883,815 shares of common stock of the Company (the “Securities”) previously registered on the Original Registration Statements. No further offering of shares of common stock or warrants will be made pursuant to this Post-Effective Amendment No. 1. All filing fees payable in connection with the registration of these Securities were previously paid by the Company in connection with the filing of the Original Registration Statements.

The information in this prospectus is not complete and may be changed. We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains, and may incorporate by reference, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or Exchange Act. These forward-looking statements relate to future events or our future performance and include, but are not limited to, statements concerning our business strategy, future commercial revenues, market growth, capital requirements, new product introductions, expansion plans and the adequacy of our funding. Other statements contained in this prospectus that are not historical facts are also forward-looking statements. We have tried, wherever possible, to identify forward-looking statements by terminology such as “may,” “will,” “could,” “should,” “expect,” “anticipate,” “intend” “plan,” “believe,” “seek,” “estimate” and other comparable terminology. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations or projections.

Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include the following:

We claim the protection of the safe harbor contained in the Private Securities Litigation Reform Act of 1995. We caution investors that any forward-looking statements presented in this prospectus or the documents incorporated by reference herein or therein, or those that we may make orally or in writing from time to time, are based upon management’s beliefs and assumptions and are made based on information available to us as of the time made and the actual outcome will be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control or ability to predict. Although we believe that our assumptions are reasonable, they are not guarantees of future performance and some will inevitably prove to be incorrect. As a result, our actual future results can be expected to differ from our expectations, and those differences may be material. Accordingly, investors should use caution in relying on past forward-looking statements, which are based on known results and trends at the time they are made, to anticipate future results or trends.

RISK FACTORS

Investment in our securities involves a high degree of risk. You should carefully consider the risks described below, as well as those risks described in the sections titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” each contained in our most recent Annual Report on Form 10-K for the year ended December 31, 2018, which has been filed with the Securities and Exchange Commission, or SEC, and is incorporated herein by reference in its entirety, as well as other information in this prospectus or in any other documents incorporated by reference. Each of the risks described in these sections and documents could adversely affect our business, financial condition, results of operations and prospects, and could result in a complete loss of your investment. This prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks mentioned above.

Risks Related to Our Business

We have a history of losses and may never become profitable.

In each of our last five years, we have experienced significant net losses and negative cash flows from operations. In 2018, we incurred a net loss of $8.1 million and had negative cash flows from operations of $6.9 million. In 2017, we incurred a net loss of $9.5 million and had negative cash flows from operations of $7.4 million. Our independent registered public accounting firm has included in its audit reports an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. If we fail to increase our revenues, we may not achieve and may not maintain profitability, we may not realize our investment in infrastructure, and may not meet our expectations or the expectations of financial analysts who report on our stock.

We may need to raise additional capital. If we are unable to raise capital, our ability to implement our current business plan and ultimately our viability as a company could be adversely affected.

At December 31, 2018, we had $5.6 million in cash and cash equivalents. Our current forecast is that our existing cash resources will be sufficient to fund our planned operations into the third quarter of 2019. Our cash resources may therefore not be sufficient to fund our business through the end of the current fiscal year. Therefore, unless we can materially grow our revenues from commercial operations during such period, we will need to raise additional capital during this fiscal year ending December 31, 2019 to continue to implement our current business plan and maintain the viability of the Company.

We believe the key factors to our future liquidity will be our ability to successfully use our expertise and our technology to generate revenues in various ways, including commercial operations, joint ventures and licenses. Because of the expected timing and uncertainty of these factors, we will need to raise funds to meet our working capital needs.

Additional financing may not be available on acceptable terms or at all. If we issue additional equity securities to raise funds, the ownership percentage of our existing stockholders would be reduced. New investors may demand rights, preferences or privileges senior to those of existing holders of common stock and could also require that we issue warrants in connection with sales of our stock. If we cannot raise any needed funds to grow our commercial resources, we might be forced to make changes to, or delay aspects of, our business plan which could adversely affect our ability to implement our current business plan and ultimately our viability as a company.

Our strategic initiative to develop a new wire platform may not prove to be successful and our decision to focus our research and development efforts on next generation power applications (NGEM) may not be the most advantageous market opportunity for HTS.

We have spent a considerable amount of resources in developing a new wire platform for power applications. In late 2010, we transitioned our research and development efforts to adapting our proprietary HTS material deposition techniques to the production of our HTS Conductus wire. In early 2018, we announced the concentration of our future Conductus wire product development efforts on NGEM to capitalize on several accelerating energy megatrends. While this refined focus is very synergistic with our program with the Department of Energy (DOE) award for the development of superconducting wire to enable NGEM, other applications for the use of HTS wire may ultimately prove to have been more advantageous to us had we not focused on NGEM.

Substantial technical and business challenges remain before we can have a commercially successful product introduction. We may not be able to overcome these challenges in a timely or cost effective manner, if at all. Such a failure could adversely impact our prospects, liquidity, stock price and carrying value of our fixed assets.

7

There are numerous technological challenges that must be overcome in order for our Conductus wire to become commercially successful and our ability to address such technological challenges may adversely affect our ability to gain customers.

Our plan is for commercial production of Conductus wire following completion of qualification orders. We have experienced in the past, and may continue to experience, delays in achieving commercial production of Conductus. Commercialization can be delayed, among other factors, by technological challenges as we seek to improve our products and processes, delays from customer qualification orders and customer analysis of those orders, and decisions made by our customers with respect to post-qualification orders. Many of the factors that affect successful commercialization of our products are affected by third party decisions.

Conductus wire is uniquely positioned to address three key technical challenges in the market: high performance, improved economics and commercial-scale capacity. To date, we, along with existing HTS wire manufacturers, have not overcome these challenges to allow for broad commercialization of HTS wire. Customers cannot purchase long-length wire with any reasonable confidence or guaranteed volume; and electric utilities lack confidence in product availability which leads to delays in their deployment roadmap. HTS wire performance is currently below what many customers require. Many power applications require high performance wire with high current carrying capacity, mechanical durability, electrical integrity with low AC losses and minimal splices. Producing high performance HTS wire has proven difficult, especially at volumes required for large scale deployment. The high demand for high performance wire available in very low volume results in a high wire price that narrows the market and limits commercial viability.

We have made significant progress in these areas, however delays in our Conductus wire development, as a result of technological challenges or other factors, may result in the introduction or commercial acceptance of our Conductus wire products later than expected.

The commercial uses of superconducting wire and superconducting wire related products are limited today, and a broad commercial market may not develop.

Even if the technological hurdles are overcome, there is no certainty that a robust commercial market for unproven HTS wire products will come to fruition. To date, commercial use of HTS wire has been limited to small feasibility demonstrations, and these projects are largely subsidized by government authorities. While customer demand is high and market forecasts project large revenue opportunity for superconducting wire in power applications, the market may not develop and superconducting wire might never achieve long term, broad commercialization. In such an event, we would not be able to commercialize our Conductus wire initiative and our business could be adversely impacted.

We have limited experience marketing and selling superconducting wire products, and our failure to effectively market and sell our superconducting wire solutions would lower our revenue and cash flow.

We have limited experience marketing and selling our Conductus wire. Once our Conductus wire is ready for commercial use, we will have to hire and develop a marketing and sales team to effectively demonstrate the advantages of our product over both more traditional products and competing superconducting products or other adjacent technologies. We may not be successful in our efforts to market this new technology.

We expect continued customer pressures to reduce our product pricing which may adversely affect our ability to operate on a commercially viable basis.

We expect to face pressure to reduce prices and accordingly, the average selling price of our Conductus wire. We anticipate customer pressure on our product pricing will continue for the foreseeable future. HTS wire is currently being sold at $250/kiloampere-meter (kA-m). At this price, HTS wire represents a significant cost of the end device. A price reduction is required for long term commercialization. Cryogenic systems, including cryocoolers and cryostats, have been developed but will also need to be cost optimized as HTS wire becomes available in volume. We have plans to further reduce the manufacturing cost of our products, but there is no assurance that our future cost reduction efforts will keep pace with price erosion. We will need to further reduce our manufacturing costs through engineering improvements and economies of scale in production and purchasing in order to achieve adequate gross margins. We may not be able to achieve the required product cost savings at a rate needed to keep pace with competitive pricing pressure. Additionally, we may be forced to discount future orders or may never reach commercial viability. If we fail to reach our cost saving objectives or we are required to offer future discounts, our business may be harmed.

8

We face competition with respect to various aspects of our technology and product development.

Our current wireless products compete on the basis of performance, functionality, reliability, pricing, quality, and compliance with industry standards. With respect to our Conductus wire materials, our competition includes American Superconductor (AMSC), SuperPower (Furukawa), SuNam , Bruker, Shanghai Superconductor, BASF, SuperOx, Fujikura, Sumitomo, THEVA, Showa Cable Systems (SWCC), and Suzhou Advanced Materials Research Institute (SAMRI). In addition, we currently supply components and license technology to several companies that may eventually decide to manufacture or design their own HTS components, rather than purchasing or licensing our technology. If we are unable to compete successfully against our current or future competitors, then our business and results of operations will be adversely affected.

We may not be able to compete effectively against alternative technologies.

Our products also compete with a number of alternative approaches and technologies. Some of these alternatives may be more cost effective or offer better performance than our products and we may not succeed in competing against these alternatives.

We currently rely on specific technologies and may not successfully adapt to the rapidly changing market environments.

We must overcome technical challenges to commercialize our Conductus wire. If we are able to do so, we will need to attain customer acceptance of our Conductus wire, and we cannot ensure that such acceptance will occur. We will have to continue to develop and integrate advances to our core technologies. We will also need to continue to develop and integrate advances in complementary technologies. We cannot guarantee that our development efforts will not be rendered obsolete by research efforts and technological advances made by others. Our business success depends upon our ability to keep pace with advancing technology, including materials, processes and industry standards.

We may experience significant fluctuations in sales and operating results from quarter to quarter.

Our quarterly results may fluctuate due to a number of factors, including:

If our customers desire to purchase products in excess of the forecasted amounts or in a different product mix, there may not be enough inventory or manufacturing capacity to fill their orders. Customer backlog may not be converted in to commercial revenues.

Due to these and other factors, our past results have limited predictive value as to our Conductus wire initiative or government contract revenues. Future revenues and operating results may not meet the expectations of stock analysts and investors. In either case, the price of our common stock could be materially adversely affected.

Worldwide economic uncertainty may adversely affect our business, operating results and financial condition.

The United States and global economies continue to experience a period of economic and financial uncertainty, which could result in economic volatility having direct and indirect adverse effects on our business, operating results and financial condition in a number of ways. For example, current or potential customers may delay or decrease spending with us, may delay paying us for previously purchased products, or may not pay us at all. In addition, this recent downturn has had, and may continue to have, an unprecedented negative impact on the global credit markets. If we are required to obtain financing in the near term to meet our working capital or other business needs, we may not be able to obtain that financing. Further, even if we are able to obtain the financing we need, it may be on terms that are not favorable to us, with increased financing costs and restrictive covenants.

9

Our reliance on a limited number of suppliers and the long lead time of components for our products could impair our ability to manufacture and deliver our systems on a timely basis.

A number of components used in our products are available from a limited number of outside suppliers due to unique designs as well as certain quality and performance requirements. Our reliance on sole or limited source suppliers involves certain risks and uncertainties, many of which are beyond our control. These include the possibility of a shortage or the discontinuation of certain key components. Any reduced availability of these parts or components when required could impair our ability to manufacture and deliver our systems on a timely basis and result in the delay or cancellation of orders, which could harm our business.

In addition, the purchase of some of our key components involves long lead times and, in the event of unanticipated increases in demand for our solutions, we may be unable to obtain these components in sufficient quantities to meet our customers’ requirements. We do not have guaranteed supply arrangements with any of these suppliers, do not maintain an extensive inventory of parts or components and customarily purchase sole or limited source parts and components pursuant to purchase orders. Business disruptions, quality issues, production shortfalls or financial difficulties of a sole or limited source supplier could materially and adversely affect us by increasing product costs, or eliminating or delaying the availability of such parts or components. In such events, our inability to develop alternative sources of supply quickly and on a cost-effective basis could impair our ability to manufacture and deliver our systems on a timely basis and could harm our business.

Our reliance on a limited number of suppliers exposes us to quality control issues.

Our reliance on certain single-source and limited-source components exposes us to quality control issues if these suppliers experience a failure in their production process or otherwise fail to meet our quality requirements.

A failure in single-source or limited-source components or products could force us to repair or replace a product utilizing replacement components. If we cannot obtain comparable replacements or effectively return or redesign our products, we could lose customer orders or incur additional costs, which could have a material adverse effect on our gross margins and results of operations.

Our ability to protect our patents and other proprietary rights is uncertain, exposing us to possible losses of competitive advantage.

Our efforts to protect our proprietary rights may not succeed in preventing infringement by others or ensure that these rights will provide us with a competitive advantage. Pending patent applications may not result in issued patents and the validity of issued patents may be subject to challenge. Third parties may also be able to design around the patented aspects of the products. Additionally, certain of the issued patents and patent applications are owned jointly with third parties. Because any owner or co-owner of a patent can license its rights under jointly-owned patents or applications, inventions made by us jointly with others are not subject to our exclusive control. Any of these possible events could result in losses of competitive advantage.

We depend on specific patents and licenses to technologies, and we will likely need additional technologies in the future that we may not be able to obtain.

We utilize technologies under licenses of patents from others for our products. These patents may be subject to challenge, which may result in significant litigation expense (which may or may not be recoverable against future royalty obligations). Additionally, we continually try to develop new products, and, in the course of doing so, we may be required to utilize intellectual property rights owned by others and may seek licenses to do so. Such licenses may not be obtainable on commercially reasonable terms, or at all. It is also possible that we may inadvertently utilize intellectual property rights held by others, which could result in substantial claims.

Intellectual property infringement claims against us could materially harm results of operations.

Our products incorporate a number of technologies, including high-temperature superconductor technology, technology related to other materials, and electronics technologies. Our patent positions, and that of other companies using high-temperature superconductor technology, is uncertain and there is significant risk that others, including our competitors or potential competitors, have obtained or will obtain patents relating to our products or technologies or products or technologies planned to be introduced by us.

We believe that patents may be or have been issued, or applications may be pending, claiming various compositions of matter used in our products. We may need to secure one or more licenses of these patents. There can be no assurances that such licenses could be obtained on commercially reasonable terms, or at all. We may be required to expend significant resources to develop alternatives that would not infringe such patents or to obtain licenses to the related technology. We may not be able to successfully design around these patents or obtain licenses to them and may have to defend ourselves at substantial cost against allegations of infringement of third party patents or other rights to intellectual property. In those circumstances, we could face significant liabilities and also be forced to cease the use of key technology.

10

Other parties may have the right to utilize technology important to our business.

We utilize certain intellectual property rights under non-exclusive licenses or have granted to others the right to utilize certain intellectual property rights licensed from a third party. Because we may not have the exclusive rights to utilize such intellectual property, other parties may be able to compete with us, which may harm our business.

Because competition for target employees is intense, we may be subject to claims of unfair hiring practices, trade secret misappropriation or other related claims.

Companies in HTS wire industries whose employees accept positions with competitors frequently claim that competitors have engaged in unfair hiring practices, trade secret misappropriation or other related claims. We may be subject to such claims in the future as we seek to hire qualified personnel, and such claims may result in material litigation. If this should occur, we could incur substantial costs in defending against these claims, regardless of their merits.

Our success depends on the attraction and retention of senior management and technical personnel with relevant expertise.

As a competitor in a highly technical market, we depend heavily upon the efforts of our existing senior management and technical teams. The loss of the services of one or more members of these teams could slow product development and commercialization objectives. Due to the specialized nature of our products, we also depend upon our ability to attract and retain qualified technical personnel with substantial industry knowledge and expertise. Competition for qualified personnel is intense, and we may not be able to continue to attract and retain qualified personnel necessary for the development of our business.

Regulatory changes could substantially harm our business.

Certain regulatory agencies in the United States and other countries set standards for operations within their territories. HTS wire is subject to a regulatory regime, which may become more strictly regulated if the market grows. Any failure or delay in obtaining necessary approvals could harm our business.

We may acquire or make investments in companies or technologies that could cause loss of value to stockholders and disruption of business.

We may explore opportunities to acquire companies or technologies in the future. Other than the acquisition of Conductus, Inc. in 2002, we have not made any such acquisitions or investments to date and, therefore, our ability as an organization to make acquisitions or investments is unproven. An acquisition entails many risks, any of which could adversely affect our business, including:

11

In addition, future acquisitions may result in potentially dilutive issuances of equity securities, or the incurrence of debt, contingent liabilities or amortization expenses or charges related to goodwill or other intangible assets, any of which could harm our business. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be seriously harmed.

If we are unable to implement appropriate controls and procedures to manage our potential growth, we may not be able to successfully offer our products and implement our business plan.

Our ability to successfully offer our products and implement our business plan in a rapidly evolving market requires an effective planning and management process. Growth in future operations would place a significant strain on management systems and resources. We expect that we would need to improve our financial and managerial controls, reporting systems and procedures, and would need to expand, train and manage our work force worldwide. Furthermore, we expect that we would be required to manage multiple relationships with various customers and other third parties.

Compliance with environmental regulations could be especially costly due to the hazardous materials used in the manufacturing process. In addition, we could incur expenditures related to hazardous material accidents.

We are subject to a number of federal, state and local governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our business. Current or future laws and regulations could require substantial expenditures for preventative or remedial action, reduction of chemical exposure, waste treatment or disposal. Any failure to comply with present or future regulations could result in the imposition of fines, suspension of production or interruption of operations. In addition, these regulations could restrict our ability to expand or could require us to acquire costly equipment or incur other significant expense to comply with environmental regulations or to clean up prior discharges.

In addition, although we believe that our safety procedures for the handling and disposing of hazardous materials comply with the standards prescribed by state and federal regulations, there is always the risk of accidental contamination or injury from these materials. To date, we have not incurred substantial expenditures for preventive action with respect to hazardous materials or for remedial action with respect to any hazardous materials accident, but the use and disposal of hazardous materials involves risk that we could incur substantial expenditures for such preventive or remedial actions. If such an accident were to occur, we could be held liable for resulting damages. The liability in the event of an accident or the costs of such remedial actions could exceed our resources or otherwise have a material adverse effect on our financial condition, results of operations or cash flows.

The reliability of market data included in our public filings is uncertain.

Since we operate in a rapidly changing market, we have in the past, and may from time to time in the future, include market data from industry publications and our own internal estimates in some of the documents we file with the Securities and Exchange Commission. The reliability of this data cannot be assured. Industry publications generally state that the information contained in these publications has been obtained from sources believed to be reliable, but that its accuracy and completeness is not guaranteed. Although we believe that the market data used in our filings with the Securities and Exchange Commission is and will be reliable, it has not been independently verified. Similarly, internal company estimates, while believed by us to be reliable, have not been verified by any independent sources.

Risks Related to Our Common Stock

Our stock price is volatile.

The market price of our common stock has been, and is expected to be, subject to significant volatility. The value of our common stock may decline regardless of our operating performance or prospects. Factors affecting our market price include:

12

Recent events have caused stock prices for many companies, including ours, to fluctuate in ways unrelated or disproportionate to their operating performance. The general economic, political and stock market conditions that may affect the market price of our common stock are beyond our control. The market price of our common stock at any particular time may not remain the market price in the future.

If we fail to maintain the listing of our common stock with a U.S. national securities exchange, the liquidity of our common stock could be adversely affected.

Our ability to publicly or privately sell equity securities and the liquidity of our common stock could be adversely affected if we are delisted from the NASDAQ Capital Market or if we are unable to transfer our listing to another stock market.

Our common stock is listed for trading on the NASDAQ Capital Market. NASDAQ has adopted a number of continued listing standards that are applicable to our common stock, including a requirement that the bid price of our common stock be at least $1.00 per share. Failure to maintain the minimum bid price can result in the delisting of our common stock from the NASDAQ Capital Market. We have previously fallen out of compliance with the minimum bid price requirement and have implemented reverse stock splits to regain compliance. Most recently, we effected a one-for-ten reverse stock split on July 24, 2018 for the purpose of regaining compliance with the minimum bid requirement following a notice from the Listing Qualifications Department of the Nasdaq Stock Market on May 22, 2018 and received a notice of re-compliance from the Listing Qualifications Department of the Nasdaq Stock Market on August 7, 2018. We currently have approximately 3,802,609 publicly held shares as of April 25, 2019. Because of NASDAQ’s continued listing standard which requires that we maintain at least 500,000 publicly held shares, our ability to effectuate a reverse split in the future is limited to a reverse split ratio that would maintain compliance with such publicly held share requirement. This effective limit to a reverse split ratio could prevent us from remediating a minimum bid price violation under circumstances where our stock price was substantially below $1.00 and a higher ratio was needed to remediate the noncompliance.

If our common stock is delisted by NASDAQ, our common stock may be eligible to trade on the OTC Bulletin Board, OTC QB or another over-the-counter market. Any such alternative would likely result in it being more difficult for us to raise additional capital through the public or private sale of equity securities and for investors to dispose of, or obtain accurate quotations as to the market value of, our common stock. In addition, there can be no assurance that our common stock would be eligible for trading on any such alternative exchange or markets.

We have a significant number of outstanding warrants and options, and future sales of the shares obtained upon exercise of these options or warrants could adversely affect the market price of our common stock.

As of December 31, 2018, we had outstanding options exercisable for an aggregate of 140,323 shares of common stock at a weighted average exercise price of $25.29 per share and warrants to purchase up to 3,796,849 shares of our common stock at a weighted average exercise price of $10.60 per share. The holders may sell these shares in the public markets from time to time under a registration statement or under Rule 144, without limitations on the timing, amount or method of sale. As our stock price rises, the holders may exercise their warrants and options and sell a large number of shares. This could cause the market price of our common stock to decline.

Our corporate governance structure may prevent our acquisition by another company at a premium over the public trading price of our shares.

It is possible that the acquisition of a majority of our outstanding voting stock by another company could result in our stockholders receiving a premium over the public trading price for our shares. Provisions of our restated certificate of incorporation and our amended and restated bylaws, each as amended, and of Delaware corporate law could delay or make more difficult an acquisition of our company by merger, tender offer or proxy contest, even if it would create an immediate benefit to our stockholders. For example, our restated certificate of incorporation does not permit stockholders to act by written consent, and our bylaws generally require ninety days advance notice of any matters to be brought before the stockholders at an annual or special meeting.

13

In addition, our board of directors has the authority to issue up to 2,000,000 shares of preferred stock and to determine the terms, rights and preferences of this preferred stock, including voting rights of those shares, without any further vote or action by the stockholders. At April 25, 2019, 1,370,710 shares of preferred stock remained unissued. The rights of the holders of common stock may be subordinate to, and adversely affected by, the rights of holders of preferred stock that may be issued in the future. The issuance of preferred stock could also make it more difficult for a third party to acquire a majority of our outstanding voting stock, even at a premium over our public trading price.

Furthermore, our certificate of incorporation also provides for a classified board of directors with directors divided into three classes serving staggered terms. These provisions may have the effect of delaying or preventing a change in control of us without action by our stockholders and, therefore, could adversely affect the price of our stock or the possibility of sale of shares to an acquiring person.

We do not anticipate declaring any cash dividends on our common stock.

We have never declared or paid cash dividends on our common stock and do not plan to pay any cash dividends in the near future. Our current policy is to retain all funds and earnings for use in the operation and expansion of our business.

USE OF PROCEEDS

We will not receive any proceeds from the sale or other disposition of the 2,883,815 shares of our common stock under this prospectus. However, we may receive up to approximately $1.8 million in gross proceeds relating to the March 2018 Warrants and $9.675 million relating to July 2018 Warrants and July 2018 Placement Agent Warrants, in each case, to the extent such warrants are exercised for cash.

However, because we are unable to predict the timing or amount of potential warrant exercises, we have not allocated any proceeds of such exercises to any particular purpose. Accordingly, all such proceeds are allocated to working capital.

It is possible that certain of the warrants may expire and may never be exercised or may be exercised on a cashless exercise basis to the extent permitted under the terms of such warrant.

DESCRIPTION OF CAPITAL STOCK

The following description of our common stock and preferred stock, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of the common stock and the preferred stock that we may offer pursuant to this prospectus. While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. For the complete terms of our common stock and preferred stock, please refer to our restated certificate of incorporation, as amended, or our certificate of incorporation, and our amended and restated bylaws, as amended, or our bylaws, which are exhibits to the registration statement of which this prospectus is a part. The terms of these securities may also be affected by the General Corporation Law of the State of Delaware. The summary below and that contained in any prospectus supplement is qualified in its entirety by reference to our certificate of incorporation and our bylaws, as either may be amended from time to time after the date of this prospectus, but before the date of any such prospectus supplement.

Authorized Capitalization

We have 252,000,000 shares of capital stock authorized under our certificate of incorporation, consisting of 250,000,000 shares of common stock and 2,000,000 shares of preferred stock, of which 706,829 have been designated as Series A Convertible Preferred Stock, par value $0.001 per share, or Series A Preferred Stock, and 4,500 have been designated as Series E Preferred Stock. As of April 25, 2019, we had 3,802,609 shares of common stock outstanding, 328,925 shares of our Series A Preferred Stock outstanding convertible into 1,827 shares of our common stock. Our authorized shares of common stock and preferred stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. If the approval of our stockholders is not so required, our board of directors may determine not to seek stockholder approval.

14

Common Stock

Holders of our common stock are entitled to such dividends as may be declared by our board of directors out of funds legally available for such purpose, subject to any preferential dividend rights of any then outstanding preferred stock. The shares of common stock are neither redeemable nor convertible. Holders of common stock have no preemptive or subscription rights to purchase any of our securities.

Each holder of our common stock is entitled to one vote for each such share outstanding in the holder’s name. No holder of common stock is entitled to cumulate votes in voting for directors.

In the event of our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive pro rata our assets that are legally available for distribution, after payments of all debts and other liabilities and subject to the prior rights of any holders of preferred stock then outstanding. All of the outstanding shares of our common stock are, and the shares of common stock issued upon the conversion of any securities convertible into our common stock will be, fully paid and non-assessable. The shares of common stock offered by this prospectus or upon the conversion of any preferred stock or debt securities or exercise of any warrants offered pursuant to this prospectus, when issued and paid for, will also be, fully paid and non-assessable.

Our common stock is listed on the NASDAQ Capital Market under the symbol “SCON.” Computershare is the transfer agent and registrar for our common stock. Its address is 250 Royall Street, Canton, MA 02021.

Preferred Stock

Our certificate of incorporation permits us to issue up to 2,000,000 shares of preferred stock in one or more series and with rights and preferences that may be fixed or designated by our board of directors without any further action by our stockholders. As of April 25, 2019, we had 328,925 shares of our Series A Preferred Stock outstanding convertible into 1,827 shares of our common stock.

Subject to the limitations prescribed in our certificate of incorporation and under Delaware law, our certificate of incorporation authorizes the board of directors, from time to time by resolution and without further stockholder action, to provide for the issuance of shares of preferred stock, in one or more series, and to fix the designation, powers, preferences and other rights of the shares and to fix the qualifications, limitations and restrictions thereof. Although our board of directors has no present intention to issue any additional preferred stock, the issuance of preferred stock could adversely affect the rights of holders of our common stock, including with respect to voting, dividends and liquidation, by issuing shares of preferred stock with certain voting, conversion and/or redemption rights. Such issuance of preferred stock may have the effect of delaying, deferring or preventing a change of control.

Preferred stock could thus be issued quickly with terms calculated to delay or prevent a change in control of our company or to make removal of management more difficult. Additionally, the issuance of preferred stock may decrease the market price of our common stock. The number of authorized shares of preferred stock may be increased or decreased, but not decreased below the number of shares then outstanding, by the affirmative vote of the holders of a majority of our common stock without a vote of the holders of preferred stock, or any series of preferred stock, unless a vote of any such holder is required pursuant to the terms of such series of preferred stock.

The following description sets forth certain general terms and provisions of the preferred stock we may issue. If we offer convertible preferred stock, such stock will be convertible into shares of our common stock. With respect to any convertible preferred stock or preferred stock (each referred to herein as preferred stock) we may choose to offer, the specific designations and rights will be described in the prospectus supplement relating to the preferred stock offered, including the following terms. Each time that we issue a new series of preferred stock, we will file with the SEC a definitive certificate of designations that will state the designation, powers, preferences, rights and qualifications, limitations and restrictions of that series of preferred stock. In addition, the prospectus supplement relating to that new series of preferred stock will specify the particular amount, price and other terms of that new series. These terms will include:

15

Any prospectus supplement filed in connection with an offering of preferred stock will describe all material terms of such series of preferred stock and all material terms of any common stock, if any, issuable upon conversion of such preferred stock. However, the description of the terms of the preferred stock to be set forth in an applicable prospectus supplement will not be complete and will be subject to and qualified in its entirety by reference to the certificate of designations or the certificate of amendment to our certificate of incorporation relating to the applicable series of preferred stock, together with our bylaws. The registration statement of which this prospectus forms a part currently does or will in the future include the certificate of designations or the certificate of amendment and our bylaws as exhibits or incorporate them by reference.

The preferred stock will, if and when issued, be fully paid and non-assessable. The holders of the preferred stock will not have preemptive rights.

Series A Convertible Preferred Stock

In October 2007, in connection with entering into an amended investment agreement with Hunchun BaoLi Communication Co. Ltd., or BAOLI, our board of directors authorized the designation and issuance of 706,829 shares of our Series A Preferred Stock. On January 8, 2008, the terms of the investment agreement with BAOLI were amended, and we issued to BAOLI and two related purchasers a total of 1,723 shares of common stock (as adjusted for reverse stock splits) and 611,523 shares of Series A Preferred Stock. Subject to the terms and conditions of our Series A Preferred Stock and to customary adjustments to the conversion rate, each share of our Series A Preferred Stock is convertible into ten twelfths of a share of our common stock so long as the number of shares of our common stock beneficially owned by BAOLI following such conversion does not exceed 9.9% of our outstanding common stock. Except for a preference on liquidation of $0.01 per share, each share of Series A Preferred Stock is the economic equivalent of ten twelfths of a share of common stock into which it is convertible. Except as required by law, the Series A Preferred Stock will not have any voting rights. For a complete description of the terms of the Series A Preferred Stock, please see the certificate of designations, filed with, and incorporated by reference into, this prospectus.

Warrants to Purchase Common Stock

As of April 25, 2019 we have warrants outstanding representing the right to acquire 913,034 shares of our common stock at a weighted average exercise price of $31.50 per share, excluding the March 2018 Warrants, the July 2018 Warrants and the July 2018 Placement Agent Warrants relating to the 2,883,815 shares of common stock offered under this prospectus (Also see “ Note 5 — Stockholders’ Equity—Warrants” in our Annual Report on Form 10-K for the year ended December 31, 2018 for further information on our outstanding warrants).

Our outstanding warrants include limitations on the ability of the holder of the warrant to exercise such warrant to the extent that such exercise would violate beneficial ownership limitations included therein. Such warrants generally provide that the holder of the warrants cannot exercise such warrant to the extent the holder would, following such exercise, beneficially own, together with other shares attributed to such holder more than 4.99% of our common stock (subject to such limitation being increased to 9.99% upon at least 60 days prior notice).

Anti-Takeover Effects of Certain Provisions of Delaware Law and Our Charter Documents

The following is a summary of certain provisions of Delaware law, our certificate of incorporation and our bylaws. This summary does not purport to be complete and is qualified in its entirety by reference to the corporate law of Delaware and our certificate of incorporation and bylaws.

Effect of Delaware Anti-Takeover Statute.  We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

Section 203 defines “business combination” to include the following:

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation, or who beneficially owns 15% or more of the outstanding voting stock of the corporation at any time within a three-year period immediately prior to the date of determining whether such person is an interested stockholder, and any entity or person affiliated with or controlling or controlled by any of these entities or persons.

Our Charter Documents.  Our charter documents include provisions that may have the effect of discouraging, delaying or preventing a change in control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by our stockholders. Certain of these provisions are summarized in the following paragraphs.

17

Classified Board of Directors.  Pursuant to our certificate of incorporation, the number of directors is fixed by our board of directors. Our directors are divided into three classes, each class to serve a three-year term and to consist as nearly as possible of one-third of the total number of directors. Pursuant to our bylaws, directors elected by stockholders at an annual meeting of stockholders will be elected by a plurality of all votes cast.

No  Stockholder Action by Written Consent.  Our bylaws provide that a special meeting of stockholders may be called only by the chairman of the board, a majority of the entire board of directors or the president. Stockholders are not permitted to call, or to require that the board of directors call, a special meeting of stockholders. Moreover, the business permitted to be conducted at any special meeting of stockholders is limited to the business brought before the meeting pursuant to the notice of the meeting given. In addition, our certificate of incorporation provides that any action taken by our stockholders must be effected at an annual or special meeting of stockholders and may not be taken by written consent instead of a meeting. Our bylaws establish an advance notice procedure for stockholders to nominate candidates for election as directors or to bring other business before meetings of our stockholders.

Change in Control Agreements.  A number of our executives have agreements with us that entitle them to payments in certain circumstances following a change in control.

SELLING STOCKHOLDERS

The common stock being offered under this prospectus includes 158,100 shares of common stock underlying the warrants being offered by the selling stockholder named below. We are registering the shares of common stock in order to permit the selling stockholders to offer the shares for resale from time to time. Except for the ownership of shares of common stock, preferred stock or warrants, the selling stockholder has not had any material relationship with us within the past three years.

The table below lists the selling stockholder and other information regarding the beneficial ownership of the shares of common stock by the selling stockholder. The second column lists the number of shares of common stock beneficially owned by each selling stockholder, based on its ownership of the shares of common stock and warrants as of April 25, 2019. The third column lists the total number of shares of common stock being offered by this prospectus by the selling stockholder.

In accordance with the terms of a registration rights agreement with the selling stockholder, this prospectus generally covers the resale of the number of shares of common stock upon exercise of the warrants, determined as if the outstanding warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided in the registration right agreement, without regard to any limitations on the exercise of the warrants. The fourth and fifth columns assume the sale of all of the shares offered by the selling stockholders pursuant to this prospectus.

Under the terms of the warrants, the selling stockholder may not exercise the warrants to the extent such exercise would cause such selling stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 4.99% of our then outstanding common stock (subject to an increase not to exceed 9.99% upon 60 days prior notice) following such exercise, excluding for purposes of such determination shares of common stock issuable upon exercise of the warrants which have not been exercised. The number of shares in the second column does not reflect this limitation. The selling stockholders may sell all, some or none of their shares in this offering.

DESCRIPTION OF WARRANTS

The following is a brief description of the warrants issued in our unregistered March 9, 2018 offering and July 30, 2018 public offering which relate to the shares of our common stock being offered by this prospectus upon exercise of such warrants. This summary does not purport to be complete in all respects. This description is subject to and qualified entirely by the terms of the forms of warrant filed as an exhibit to the registration statement of which this prospectus is a part.

Common Stock

The material terms of our common stock and our other capital stock are described in the section of this prospectus entitled “Description of Capital Stock” beginning on page 14 of this prospectus.

Warrants to Purchase Common Stock

The material terms of the warrants to be issued are summarized below. This summary does not purport to be complete in all respects. This description is subject to and qualified entirely by the terms of the form of warrant filed as an exhibit to the registration statement of which this prospectus is a part.

March 9, 2018 Warrants

On March 9, 2018, the Company issued an aggregate of 158,100 warrants to purchase common stock at an exercise price of $11.40 per share (as adjusted for a subsequent reverse stock split), exercisable from the date of issuance until the five and a half year anniversary of the date of issuance. The warrants were issued to purchasers of the Company’s common stock and pre-funded warrants purchased in the concurrent March 2018 registered offering.

The warrants may not be exercised by the holder to the extent that the holder, together with its affiliates, would beneficially own, after such exercise more than 4.99% (or at the election of a purchaser prior to the date of issuance, 9.99%) of the shares of common stock then outstanding (subject to the right of the holder to increase or decrease such beneficial ownership limitation upon not less than 61 days prior notice provided that such limitation cannot exceed 9.99%). The warrants are exercisable for cash or, solely in the absence of an effective registration statement or prospectus, by cashless exercise.

July 30, 2018 Warrants

On July 30, 2018, the Company issued an aggregate of 2,571,429 warrants to purchase common stock at an exercise price of $3.50 per share, exercisable from the date of issuance until the five and a half year anniversary of the offering. The warrants were issued to purchasers of the Company’s common stock and pre-funded warrants purchased in the concurrent March 2018 registered offering. In addition, in connection with such July 2018 offering, the Company issued an additional 154,286 warrants to purchase common stock at an exercise price of $4.38 per share to the placement agent in such offering. The placement agent warrants also expire on the five and a half year anniversary of the offering.

The warrants may not be exercised by the holder to the extent that the holder, together with its affiliates, would beneficially own, after such exercise more than 4.99% (or at the election of a purchaser prior to the date of issuance, 9.99%) of the shares of common stock then outstanding (subject to the right of the holder to increase or decrease such beneficial ownership limitation upon not less than 61 days prior notice provided that such limitation cannot exceed 9.99%). The warrants are exercisable for cash or, solely in the absence of an effective registration statement or prospectus, by cashless exercise.

PLAN OF DISTRIBUTION

We will deliver shares of our common stock offered hereby upon exercise of the warrants we issued on March 9, 2018 and July 30, 2018. As of the date of this prospectus, these warrants were exercisable for a total of up to 2,883,815 shares of our common stock (158,100 shares in connection with the March 9, 2018 issuance and 2,725,715 shares in connection with the July 30, 2018 issuance). We will not issue fractional shares upon exercise of these warrants. Each of these warrants contains instructions for exercise. In order to exercise any of these warrants, the holder must deliver to us or our transfer agent the information required in the warrants, along with payment for the exercise price of the shares to be purchased. We will then deliver shares of our common stock in the manner described above in the section titled “Description of Warrants.”

With respect to the shares of common stock that may be offered by the Selling Stockholder, its assignees and successors-in-interest may, from time to time, such holder may sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

The Selling Stockholder may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

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

21

The Selling Stockholder and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholder and agreed to indemnify the purchasers in the July 2018 offering against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to register the common stock offered by the selling stockholder under this prospectus until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect, (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect or (iii) until such securities are no longer Registrable Securities as defined in the registration rights agreement we entered into with the selling stockholder.

The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

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

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the various expenses to be incurred in connection with the sale and distribution of our securities being registered hereby, all of which will be borne by us (except any underwriting discounts and commissions and expenses incurred for brokerage, accounting, tax or legal services or any other expenses incurred in disposing of the shares). All amounts shown are estimates except the SEC registration fee and the FINRA filing fee.

Section 145 of the Delaware General Corporation Law, or the Delaware Law, provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses including attorneys’ fees, judgments, fines and amounts paid in settlement in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation — a “derivative action”), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys’ fees) incurred in connection with defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Under Section 145, a corporation shall indemnify an agent of the corporation for expenses actually and reasonably incurred if and to the extent such person was successful on the merits in a proceeding or in defense of any claim, issue or matter therein.

We may from time to time be subject to Section 2115 of the California Corporations Code, or the California Code, according to which Section 317 of the California Code applies to the indemnification of our officers and directors. Under Section 317 of the California Code, permissible indemnification by a corporation of its officers and directors is substantially the same as permissible indemnification under Section 145 of the Delaware Law, except that (i) permissible indemnification does not cover actions the person reasonably believed were not opposed to the best interests of the corporation, as opposed to those the person believed were in fact in the best interests of the corporation, (ii) the Delaware Law permits advancement of expenses to agents other than officers and directors only upon approval of the board of directors, (iii) in a case of stockholders approval of indemnification, the California Code requires certain minimum votes in favor of such indemnification and excludes the vote of the potentially indemnified person and (iv) the California Code only permits independent counsel to approve indemnification if an independent quorum of directors is not obtainable, while the Delaware Law permits the directors in any circumstances to appoint counsel to undertake such determination.

Section 145 of the Delaware Law and Section 317 of the California Code provide that they are not exclusive of other indemnification that may be granted by a corporation’s charter, bylaws, disinterested director vote, stockholders vote, agreement or otherwise. The limitation of liability contained in our restated certificate of incorporation, as amended, and the indemnification provision included in our amended and restated bylaws, as amended, are consistent with Delaware Law Sections 102(b)(7) and 145 and California Code Section 317. We have purchased directors and officers liability insurance.

Section 145 of the Delaware Law authorizes court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933. Our restated certificate of incorporation, as amended, and amended and restated bylaws, as amended, provide for indemnification of our directors, officers, employees and other agents to the maximum extent permitted by the Delaware Law. In addition, we have entered into indemnification agreements with our officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling our company pursuant to such provisions, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in such Act and is therefore unenforceable.

The undersigned registrant hereby undertakes:

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

II-2

to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability 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.

(6) 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 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.

(7) The undersigned registrant hereby undertakes that:

(i) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus as 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 of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

(ii) For the purpose of determining any liability under the Securities Act of 1933, 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.

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