TABLE OF CONTENTS

SUMMARY

This summary highlights information contained elsewhere in this prospectus. We urge you to read this entire prospectus carefully, including the “Risk Factors” section, before making an investment decision.

Lighting Science Group Corporation

Lighting Science Group Corporation is a Delaware corporation incorporated on June 16,1988. On June 1, 2004, Lighting Science Group acquired 100% of the outstanding common stock of Lighting Science, Inc., a Delaware corporation that developed and owned certain intellectual property related to the design and development of lighting products utilizing light emitting diodes, or LEDs, as a source of light. With our acquisition of Lighting Science, Inc., we entered the field of solid-state lighting. We began conducting operations under the name Lighting Science Group Corporation on January 1, 2005.

As of the date of this prospectus, Lighting Science Group continues with its plans to develop and sell products based upon the intellectual property acquired in the acquisition of Lighting Science, Inc. and which is related to the design and development of lighting products utilizing light emitting diodes as a source of light.

Our principal executive offices are located at 2100 McKinney Avenue, Suite 1555, Dallas, Texas 75201. Our telephone number is (214) 382-3630.

Market Overview

The global lighting market has annual sales exceeding $40 billion, with the U.S. market alone contributing $12 billion to $15 billion annually. More importantly, the lighting market consumes over 20% of the world’s energy on an annual basis. This is the target market that management believes will evolve to solid-state lighting. Industry studies have predicted that LED-based lighting will replace over 40% of incandescent lighting applications by 2025. It is estimated that by the same year solid-state lighting could reduce the global amount of electricity used for lighting by 50%. We believe that no other use of electricity can offer such a large energy-savings potential.

Competitive Advantages

Through the development of its Optimized Digital Lighting™, or ODL™, technology, Lighting Science Group believes that it has begun to close the gap between the theoretical performance capability of today’s LEDs and the current level of LED performance in the existing generation of general illumination products. With our enabling technologies, we believe that we have positioned ourselves at the forefront of the emerging solid state lighting industry and will be able to compete in the marketplace.

Products/Distribution

Lighting Science Group is positioned to introduce its ODL products through traditional commercial and retail distribution channels, on a direct basis through its sales force, and through our shared savings plans with larger commercial and municipal customers (See "Plan Of Operation" for a discussion of our shared savings program). Our near-term product portfolio includes flashlights and floodlights for the consumer market, cabinet lighting for the furniture manufacturing and hospitality markets, outdoor lighting products for parking garages and street lighting for the commercial and municipal markets.

The Private Placement

On May 12, 2005, we entered into a definitive Securities Purchase Agreement with Western Reserve Hedged Equity, LP, AG Domestic Convertibles, L.P., A.G. Offshore Convertibles, Ltd., the Gryphon Master Fund, L.P., the GSSF Master Fund, L.P., Xerion Partners I LLC, Xerion Partners II Master Fund Limited, Telemark Asset Management, LLC and certain other accredited investors including certain officers and directors of Lighting Science Group, collectively referred to as the Purchasers, for the private placement of 6% convertible preferred stock of Lighting Science Group, $.001 par value per share, pursuant to which the Purchasers bought 2,260,966 shares of the preferred stock at $3.20 per share for an aggregate purchase price of $7,235,086. Additionally, warrants, a registration rights agreement and lock-up agreements with affiliates and certain unaffiliated stockholders of Lighting Science Group were also entered into and executed. A certificate of designation that sets forth the rights, preferences, terms and conditions of the preferred stock was filed with the Secretary of State of the State of Delaware on May 10, 2005.

The preferred stock may be converted into shares of common stock. The preferred stock has an initial conversion price of $0.80 per share of common stock subject to full ratchet anti-dilution provisions. The Purchasers also received warrants to purchase an additional 6,782,889 shares of common stock at an exercise price of $0.96 per share (subject to adjustment pursuant to anti-dilution provisions). The warrants have a term of five years from the closing date of the transaction. Merriman Curhan Ford & Co. acted as placement agent for this transaction. MRM Capital LP acted as our financial advisor. Warrants to purchase a total of 639,844 shares of common stock at an exercise price of $1.50 per share (subject to adjustment pursuant to anti-dilution provisions) were issued to Merriman and MRM in conjunction with this transaction.

The lock-up agreements provide that all affiliated stockholders of Lighting Science Group will not offer sell, contract to sell, pledge or otherwise dispose of common stock or securities convertible into, or exchangeable or exercisable for, common stock, subject to certain exceptions for a period of 180 days following the date that a registration statement is declared effective with regard to such common stock. The lock-up agreements will expire on February 19, 2006. Shares of common stock that affiliates held prior to the private placement will not be included in this registration statement.

Lock-up agreements were also entered into with certain unaffiliated stockholders covering a total of 14,260,823 shares of our common stock. Such lock-up agreements provide that such unaffiliated stockholders will not offer to sell, contract to sell, pledge or otherwise dispose of common stock or securities convertible into, or exchangeable or exercisable for, our common stock, subject to certain exceptions, for 180 days following the effective date of a registration statement regarding the common stock. Shares of common stock held by unaffiliated stockholders who have executed a lock-up agreement will be included in this registration statement. Such lock-up agreements will also expire on February 19, 2006.

Neither the preferred stock nor the warrants have been registered under the Securities Act of 1933, as amended, and may not be subsequently offered or sold by investors in the United States absent registration or an applicable exemption from the registration requirement. Pursuant to the registration rights agreement, we have agreed with the purchasers of these securities to register the common stock underlying these securities for public resale. This prospectus has been prepared, and the registration statement, including all amendments thereto, of which this prospectus is a part has been filed with the SEC, in order to satisfy our obligations to the purchasers of these securities.

Accordingly, this prospectus covers:

·   the resale by the selling stockholders of shares of our common stock issued upon conversion of the selling stockholders’ preferred stock.

·   the resale by the selling stockholders of shares of our common stock issuable upon exercise of the warrants.

·   the resale by certain unaffiliated, selling stockholders of our common stock purchased prior to the date of the Securities Purchase Agreement and who have executed a lock-up agreement.

·   any additional shares of our common stock that may be issued pursuant to anti-dilution provisions applicable to the preferred stock and the warrants.

Investing in our securities involves risks. You should carefully consider the information under “Risk Factors” section of this prospectus and the other information included or incorporated by reference in this prospectus before investing in our securities.

RISK FACTORS

An investment in our common stock is risky. You should carefully consider the following risks, as well as the other information contained in this prospectus. If any of the following risks occur, our business could be harmed. In that case, the trading price of our common stock could decline and you might lose all or part of your investment.

Risks Related to Lighting Science’s Business

Because We Have A Lack Of Revenues And A History Of Losses, We May Be Unable To Continue Operations Unless We Can Generate Operating Income By Completing Development Of Our Products, Obtaining Approval of Intellectual Property Rights And Marketing The Products.

Since we emerged from bankruptcy on September 26, 2003, we have sustained operating losses. For the years ended December 31, 2005 and 2004, we had limited revenues from operations of $72,564 and $3,404, respectively, and as of December 31, 2005 and 2004, we had an accumulated deficit of $10,159,116 and $4,180,193, respectively. Lighting Science Group expects to begin generating significant revenues from the sale of its products in the first half of 2006. The ability to generate revenue is, however, dependent on receiving purchase commitments from new customers as well as the timing that such purchase commitments, if any, are received.

It Is Difficult To Evaluate The Likelihood That We Will Achieve Or Maintain Profitability In The Future.

We are emerging from being a development stage company to one that is focusing on sales and growth in the lighting industry marketplace. Accordingly, since acquiring Lighting Science, Inc. and refocusing on the sale and development of the Optimized Digital Lighting products, we have not yet achieved profitability on an annual basis. As we begin this next stage concentrating on sales and growth, our limited operating history makes an evaluation of our future prospects difficult. If we do not achieve sufficient growth in our revenues or achieve and sustain profitability in the future, we may be unable to continue operations.

If We Are Unable To Obtain Outside Capital When Needed, In The Amount Needed, Our Business And Future Prospects Will or Could Be Adversely Affected And We Could Be Forced To Suspend Or Discontinue Operations.

Although no assurance can be given, we believe that our current cash and investment balances together with revenues received from the sale of our products will be sufficient to meet our operating needs through the end of 2006. The actual amount of funds that we will need will be determined by many factors, some of which are beyond our control. These factors include the success of our research and development efforts (including any unanticipated delays), the costs and timing of obtaining new patent rights, regulatory changes, competition, technological developments in the market, timing of sales transactions and amount of working capital investments Lighting Science Group is required to make.

Potential sources of outside capital include entering strategic business relationships, public or private sales of shares of our capital stock or debt or other similar arrangements. We do not have any committed sources of outside capital at this time. It is uncertain whether we will be able to obtain outside capital when we need it or on terms that would be acceptable. If we raise funds by selling additional shares of our common stock or securities convertible into our common stock, the ownership interest of our existing stockholders will be diluted. If we are unable to obtain outside capital when needed, in the amount needed, our business and future prospects will or could be adversely affectedand we could be forced to suspend or discontinue operations.

Because We Rely Upon Ronald E. Lusk And Other Key Personnel, A Loss Of Any Key Personnel Could Prevent Or Significantly Delay The Achievement Of Our Goals.

Our success will depend to a large extent on the abilities and continued service of Ronald E. Lusk and other key personnel. The loss of Mr. Lusk, the CEO, or other key personnel could prevent or significantly delay the achievement of our goals. We have employment agreements with Ronald E. Lusk, Fredric S. Maxik, Stephen Hamilton, J. Michael Poss and K. Shane Hartman. We maintain key man life insurance policy with respect to Fredric S. Maxik. If any of these persons were to leave Lighting Science Group, it could delay implementation of our business plan and marketing efforts. Should any of them leave, we would seek to replace them as soon as possible. As we grow, we will need to add additional management and other personnel. Competition for qualified personnel in our industry is intense, and our success will depend on our ability to attract and retain highly skilled personnel. We cannot assure you that our efforts to obtain or retain such personnel will be successful.

The recent resignations of the Company’s President, Chief Financial Officer and Executive Vice President Could Prevent Or Significantly Delay The Achievement Of Our Goals.

In October 2005, Lighting Science Group’s President, Stan T. Waldrop, and Executive Vice President, Philip R. Lacerte, resigned their positions with Lighting Science Group. In November 2005, Michael N. Lavey, our Chief Financial Officer also resigned and was replaced by Stephen A. Hamilton on November 11, 2005. Mr. Waldrop has agreed to provide transition consulting for a six-month period for which he was issued 50,000 shares of our common stock. In exchange for being released from his employment agreement, Mr. Lacerte agreed to return 100,000 shares of common stock to the Company. Although we have hired a new Chief Financial Officer, we have not yet replaced Mr. Waldrop or Mr. Lacerte and we are unable assess whether the loss of these officers could prevent or significantly delay the achievement of our goals. Additionally, we are unable to assess the impact the resignations of these executives will have on our other employees.

Customer Acceptance Of Our Products Is Dependent On Our Ability To Meet Changing Requirements.

Customer acceptance of our products is significantly dependent on our ability to offer products that meet the changing requirements of our customers. Any decrease in the level of customer acceptance of our products could have a material adverse effect on us.

Our Future Performance Is Dependent Upon Attracting And Retaining Customers.

We are moving from a research and development stage company to one which is focused on sales and growth. If we are unsuccessful in our attempts to commercialize our products and attract and retain a solid customer base, then we will be unable to continue as a going concern.

The Markets For Many Of Our Products Are Characterized By Changing Technology.

The markets for many of our products are characterized by changing technology, new product introductions, product enhancements and evolving industry standards. The introduction or enhancement of products embodying new technology or the emergence of new industry standards could render existing products obsolete or result in short product life cycles. Accordingly, our ability to compete is in part dependent on our ability to continually offer enhanced and improved products.

We are Dependent on Key Outside Contract Manufacturers to Deliver a Custom Product with the Highest Performance and Shortest Time to Market.

We depend on key outside contract manufacturers’ equipment and assembly processes. We believe that these key manufacturing and assembly processes give us the flexibility and responsiveness to meet our customer delivery schedule and performance specification with a custom product. This value proposition is an important component of our offering to our customers. A loss of these capabilities or access to key outside contract manufacturers could have an adverse effect on our existing operations and new business growth.

Our Industry Is Sensitive To Changing Economic Conditions.

We believe that many factors affect our industry, including consumer confidence in the economy, interest rates and credit availability. The overall economic climate or Gross National Product growth has a direct impact on our customers and the demand for our products. We cannot assure you that our business will not be adversely affected as a result of an industry or general economic downturn.

If Our Optimized Digital Lighting Technology Does Not Achieve Market Acceptance, Prospects For Our Growth And Profitability May Be Limited.

Our future success depends on market acceptance of our Optimized Digital Lighting technology. Potential customers may be reluctant to adopt solid-state lighting as an alternative to traditional lighting technology because of its higher initial cost or perceived risks relating to its novelty, reliability, usefulness and cost-effectiveness when compared to other lighting sources available in the market. If acceptance of solid-state lighting in general, and of our ODL lighting systems in particular, does not continue to grow within the high performance lighting markets that we may serve directly, and in the markets that we serve indirectly through future customers, then opportunities to increase our revenues and operate profitably may be limited.

If Critical Components That We Currently Purchase From Our Suppliers Become Unavailable, We May Incur Delays In Shipment Which Could Damage Our Business.

We depend on our suppliers for certain components critical to the manufacture of our solid-state lighting systems. For certain types of LEDs used in our lighting systems, we currently have a limited number of suppliers. We depend on our vendors to supply critical components in adequate quantities and consistent quality and at reasonable costs. Finding a suitable alternate supply of required components and obtaining them in needed quantities may be a time-consuming process and there can be no assurance that an adequate alternative source of supply could be found at an acceptable cost.

We could experience shortages of standard electronic components as well as custom components specific to our products. If our suppliers are unable to meet our demand for critical components at reasonable costs, and if we are unable to obtain an alternative source or the price for an alternative source is prohibitive, our ability to maintain timely and cost-effective production of our products will or could be harmed. Because we generally rely on purchase orders rather than long-term contracts with our suppliers, we cannot predict with certainty our ability to obtain components in adequate quantities and at acceptable prices in the longer term. If we are unable to obtain components in adequate quantities, we may incur delays in shipment or be unable to meet demand for our products which could harm our revenues and damage our reputation and our relationships with customers and prospective customers.

The principal raw materials used in the manufacture of our LED components and sensor assemblies are silicon wafers, gold wire, lead frames, and a variety of packages and substrates, including metal, printed circuit board, flex circuits, ceramic and plastic packages. All of these raw materials can be obtained from several suppliers. From time to time, particularly during periods of increased industry-wide demand, silicon wafers and other materials have been in short supply. Any significant interruption in the supply of these raw materials could have a material adverse effect upon us.

If The Companies To Which We Outsource The Manufacture Of Our Products Fail To Meet Our Requirements For Quality, Quantity And Timeliness, Our Revenues And Reputation In The Marketplace Could Be Harmed.

We outsource the manufacture of our products, and do not own or operate a manufacturing facility. We currently depend on a small number of contract manufacturers to manufacture our products at plants in various locations throughout the world. These manufacturers supply all necessary raw materials (other than certain critical components such as LEDs, which we procure directly), provide all necessary facilities and labor to manufacture our products, and stock and arrange for transport of our finished goods, generally by ship, to our distributors and customers. If these companies were to terminate their arrangements with us or fail to provide the required capacity and quality on a timely basis, we would be unable to manufacture and ship our products until replacement manufacturing services could be obtained. To qualify a new contract manufacturer, familiarize it with our products, quality standards and other requirements, and commence volume production may be a costly and time-consuming process. We cannot assure you that we would be able to establish alternative manufacturing relationships on acceptable terms.

Our reliance on contract manufacturers involves certain risks, including the following:

·   lack of direct control over production capacity and delivery schedules;

·   lack of direct control over quality assurance, manufacturing yields and production costs;

·   risk of loss of inventory while in transit; and

·   risks associated with international commerce, including unexpected changes in legal and regulatory requirements, changes in tariffs and trade policies, risks associated with outbreaks of disease, risks associated with the protection of intellectual property and political and economic instability.

Any interruption in our ability to manufacture and distribute products could result in delays in shipment, lost sales, limited revenue growth and damage to our reputation in the market, all of which would adversely affect our business.

If We Are Unable To Increase Production Capacity For Our Products In A Timely Manner, We May Incur Delays In Shipment And Our Revenues And Reputation In The Marketplace Could Be Harmed.

An important part of our business strategy is the expansion of production capacity for our products. We plan to increase production capacity by adding new contract manufacturers and by expanding capacity with our existing contract manufacturers. Our ability to successfully increase production capacity will depend on a number of factors, including the following:

·   identification and availability of appropriate and affordable contract manufacturers;

·   ability of our current contract manufacturers to allocate more existing capacity to us or their ability to add new capacity quickly;

·   availability of critical components used in the manufacture of our products;

·   establishment of adequate management information systems, financial controls and supply chain management and quality control procedures; and

·   ability of our future contract manufacturers to implement our manufacturing processes.

If we are unable to increase production capacity for our products in a timely manner while maintaining adequate quality, we may incur delays in shipment or be unable to meet increased demand for our products which could harm our revenues and damage our reputation and our relationships with customers and prospective customers.

If Demand For Our Optimized Digital Lighting And Other Light Products In The General Lighting Market Fails To Emerge, We May Not Be Able To Carry Out Long-Term Business Strategies.

Our long-term business strategy includes penetration of the general lighting market with our ODL and other lighting products. Failure to obtain and incorporate into our products, on a timely basis, LEDs having satisfactory performance, quality and cost characteristics could delay our planned introduction of our products, or reduce the attractiveness to potential customers of our products that incorporate LEDs.

In addition, the characteristics of our Optimized Digital Lighting technology that we believe are desired by customers in the high performance color lighting markets that we currently serve may not provide us with competitive advantages in the general lighting market. For example, end-users in the general lighting market may not require the complex, dynamic lighting effects or sophisticated digital control that our systems provide. Similarly, if LED manufacturers are able to develop single LEDs that produce light of acceptable consistency and color, our color temperature control technologies may be of less importance in the general lighting market than in the high performance color lighting market.

We have devoted, and intend to continue to devote, substantial resources to the development of our products and technologies suitable for use in the general lighting market. If demand for these products and technologies in the general lighting market does not develop and we do not receive revenue to offset these expenditures, our profitability will or could be harmed and our ability to carry out our long-term business strategy may be adversely affected.

If We Are Not Able To Compete Effectively, Our Prospects For Future Success Will Be Jeopardized.

In the high performance lighting markets in which we plan to sell our Optimized Digital Lighting and other LED lighting systems, and in the licensing markets in which we participate, our systems compete with lighting products utilizing traditional lighting technology provided by many vendors. In addition, we face competition from a smaller number of manufacturers, including manufacturers of traditional lighting equipment that have developed one or more solid-state lighting products. Some of our competitors, particularly those that offer traditional lighting products, are larger companies with greater resources to devote to research and development, manufacturing and marketing than we have.

We expect to encounter competition from some of the competitors described above. Additionally, to the extent that we seek to introduce Optimized Digital Lighting products for use in general lighting applications, such as retrofit bulbs and lamps for standard fixtures, we expect to encounter competition from large, established companies in the general lighting industry such as General Electric, Matsushita, Osram Sylvania and Philips Lighting, each of which has, we believe, undertaken initiatives to develop LED technology. These companies have global marketing capabilities and substantially greater resources to devote to research and development and other aspects of the development, manufacture and marketing of solid-state lighting systems than we have. We will also be competing with domestic and international manufacturers of lighting components of various sizes and resources. We cannot assure you that we will be able to compete successfully in such markets against these or future competitors.

In each of our markets, we anticipate the possibility that LED manufacturers, including those that currently supply us with LEDs, may seek to compete with us by introducing more complete systems that do not infringe upon our patents.

Our competitors’ lighting technologies and products may be more readily accepted by customers than our products. Additionally, to the extent that competition in our markets intensifies, we may be required to reduce our prices in order to remain competitive. If we do not compete effectively, or if we reduce our prices without making commensurate reductions in our costs, our revenues and profitability, and our future prospects for success may be harmed.

If We Are Unable To Manage Our Growth Effectively, Our Future Growth, Profitability And Liquidity Could Be Adversely Affected.

We anticipate significant growth in our business. Our anticipated growth is expected to place significant strain on our limited research and development, sales and marketing, operational and administrative resources. To manage any future growth, we must continue to improve our operational and financial systems and expand, train and manage our employee base. For example, we must implement new modules of our management information system, hire and train new sales representatives and expand our supply chain management and quality control operations. We recently hired a new chief financial officer and we will need to make other additions to our operations and administrative management teams. If we are unable to manage our growth effectively, our future growth may be limited, we may be unable to operate profitability and we may not be able to effectively pursue our business plan.

We Have Limited Experience Conducting Operations Internationally, Which May Make Expansion More Difficult And Costly Than We Expect And Adversely Affect Our Revenue Growth And Profitability.

We currently outsource the manufacture of our products to international facilities. To the extent that we continue to outsource to international locations, we are exposed to differing laws, regulations and business cultures than what we experience domestically and that may adversely impact our business. We may also be exposed to economic and political instability and international unrest. Although we hope to enter into agreements with manufacturers, shippers and distributors that attempt to minimize these risks, there is no assurance that such agreements will be honored or that we will be able to adequately protect our interests.

We intend to continue outsourcing the manufacture of our products internationally for the foreseeable future. There are many barriers and risks to operating successfully in the international marketplace, including the following:

·   foreign currency risks;

·   dependence on foreign manufacturers, shippers and distributors;

·   compliance with multiple, conflicting and changing governmental laws and regulations; and

·   import and export restrictions and tariffs.

If we are not able to successfully deliver our products and services to our anticipated markets, our revenue growth and profitability may be adversely affected.

Our Products Could Contain Defects, Which Could Reduce Sales Of Those Products Or Result In Claims Against Us.

Despite testing by us and our customers, defects could be found in the future in our existing or future products. This could result in, among other things, a delay in the recognition or loss of revenues, loss of market share or failure to achieve market acceptance. These defects may cause us to incur significant warranty, support and repair costs, divert the attention of our engineering personnel from our product development efforts and harm our relationship with our customers. The occurrence of these problems could result in the delay or loss of market acceptance of our products and would likely harm our business. Defects, integration issues or other performance problems in our products could result in personal injury or financial or other damages to our customers or could damage market acceptance of our products. Our customers could also seek damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend.

Risks Related To Intellectual Property

If We Are Unable To Respond Effectively As New Lighting Technologies And Market Trends Emerge, Our Competitive Position And Our Ability To Generate Revenues And Profits May Be Harmed.

The emergence of solid-state lighting is transforming the lighting industry. To be successful, we will need to keep pace with rapid changes in lighting technology, changing customer requirements, new product introductions by competitors and evolving industry standards, any of which could render our existing products obsolete if we fail to respond in a timely manner. For example, if new solid-state lighting devices are introduced that can be controlled by methods not covered by our proprietary technology, or if effective new sources of light other than solid-state devices are discovered, our current products and technology could become less competitive or obsolete. If others develop innovative proprietary lighting technology that is superior to ours, or if we fail to accurately anticipate technology and market trends and respond on a timely basis with our own innovations, our competitive position may be harmed and we may not achieve sufficient growth in our revenues to attain, or sustain, profitability.

If We Are Unable to Obtain and Protect Our Intellectual Property Rights, Our Ability to Commercialize Our Products Could Be Substantially Limited.

We have filed twenty-one (21) patent applications. From these applications, two (2) patents have been allowed and seventeen (17) are pending approval. Two have been abandoned in favor of continuing application.

We cannot assure you that any patent applications filed by us, or by others under which we have rights, will result in patents being issued in the United States or foreign countries. In addition, we cannot guarantee that patents that have been or will be issued will afford meaningful protection for our products. Competitors may develop products similar to our products that do not conflict with our patents. Others may challenge our patents and, as a result, our patents could be narrowed or invalidated. We cannot assure that we will be able to afford the legal costs associated with defending or enforcing any of our patents. We have not received any communications, allegations, complaints or threats of litigation relating to patent infringement to date.

If We Are Unable To Protect Our Intellectual Property Rights Adequately, The Value Of Our Products Could Be Diminished.

We utilize proprietary design rules and processing steps in the development and fabrication of our LED products. In addition, we have filed twenty-one (21) patent applications for the protection of the intellectual property used in our products and two (2) patents have been allowed. There can be no assurance that any of the patent applications will be approved or any patents, if issued, will provide us with significant competitive advantages, or that challenges will not be instituted against the validity or enforceability of any patent owned by us, or, if instituted, that such challenges will not be successful. The cost of litigation to uphold the validity and to prevent the infringement of a patent could be substantial and could have a material adverse effect on our operating results. Furthermore, there can be no assurance that our ODL technology will not inadvertently infringe on patents or rights owned by others or licenses which might not be available to us. Based on limited patent searches, contacts with others knowledgeable in the field of LED technology, and a review of the published materials, we believe that our competitors hold no patents, licenses or other rights to the ODL technology which would preclude us from pursuing our intended operations.

In some cases, we may rely on trade secrets to protect our innovations. There can be no assurance that trade secrets will be established, that secrecy obligations will be honored or that others will not independently develop similar or superior technology. To the extent that consultants, key employees or other third parties apply technological information independently developed by them or by others to our projects, disputes might arise as to the proprietary rights to such information that may not be resolved in our favor.

We May Incur Substantial Costs Or Lose Important Rights As A Result Of Litigation Or Other Proceedings Relating To Patent And Other Intellectual Property Rights.

In recent years, there has been significant litigation involving patents and other intellectual property rights. Since it is possible for patent applications to be retained in secrecy by the U.S. Patent and Trademark Office until and unless a patent issues, it is not possible for us to know whether United States patent applications are pending that would be infringed by the use of our technology or a part thereof, thus substantially interfering with the future conduct of our business. In addition, there may be issued patents in the U.S. or other countries that are pertinent to our business of which we are not aware. We could be sued by other parties for patent infringement in the future. Such lawsuits could subject us to liability for damages and invalidate our proprietary rights. In addition, intellectual property lawsuits may be brought by third parties against LED and licensing customers that incorporate our ODL technology in their products.

In addition to being subject to claims by third parties that we have infringed upon their proprietary rights, we may in the future assert our intellectual property rights by instituting legal proceedings against others. We cannot assure you that we will be successful in enforcing our patents in any lawsuits that we may commence. Defendants in any litigation we commence to enforce our patents may attempt to establish that our patents are invalid or are unenforceable. Thus, any patent litigation we commence could result in a determination that one or more of our patents are invalid or unenforceable.

Whether we are defending the assertion of intellectual property rights against us or asserting our own intellectual property rights against others, such litigation can be complex, costly, protracted and highly disruptive to our business operations by diverting the attention and energies of our management and key technical personnel. As a result, the pendency or adverse outcome of any intellectual property litigation to which we are subject could disrupt our business operations, require the incurrence of substantial costs and subject us to significant liabilities, each of which could severely harm our business. Plaintiffs in intellectual property cases often seek injunctive relief. Any intellectual property litigation commenced against us could force us to take actions that could be harmful to our business, including the following:

·   stop selling our products or using technology that contains the allegedly infringing intellectual property;

·   attempt to obtain a license to the relevant intellectual property, which may not be available on reasonable terms or at all; and

·   attempt to redesign products that embody the allegedly infringing intellectual property.

If we are forced to take any of the foregoing actions, we may be unable to manufacture and sell our Optimized Digital Lighting, LED and/or solid-state lighting systems, which could seriously harm our business. We may not be able to develop, license or acquire non-infringing technology under reasonable terms, if at all. These developments would result in an inability to compete for customers and would adversely affect our ability to increase our revenues. The measure of damages in intellectual property litigation can be complex, and is often subjective or uncertain. If we were to be found liable for infringement of proprietary rights of a third party, the amount of damages we might have to pay could be substantial and is difficult to predict.

If We Are Unable To Obtain And Maintain Patent Protection For Our Technology And Otherwise Protect Our Intellectual Property, The Value Of Our Technology And Products Will Be Adversely Affected.

We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent they are covered by valid and enforceable patents or are effectively maintained as trade secrets. To date, we have applied for twenty-one (21) patents and two (2) patents have been allowed. Because the patent position of technology companies involves complex legal, scientific, and factual questions, the issuance, scope, validity and enforceability of our patents cannot be predicted with certainty. Patents that we have applied for or patents which have been issued to us may be rejected or invalidated or their enforceability challenged, and they may not provide us with competitive advantages against others with similar products and technology. Furthermore, others may independently develop similar products or technology or duplicate or design around any technology that we have developed.

We also attempt to protect our proprietary information with contractual arrangements and the use of trade secret laws. Our employees and consultants generally enter into agreements containing provisions with respect to confidentiality and the assignment of rights to inventions made by them while in our employ. The protection offered by patents or trade secret laws or by these agreements may not be sufficient to protect our intellectual property and existing or future patents could be challenged, invalidated or circumvented. Moreover, the laws of many foreign countries, including The People’s Republic of China, where some of our contract manufacturers are located, do not protect our intellectual property rights to the same extent as do the laws of the United States.

Risks Related to This Offering

Risks Relating To Our Common Stock.

Our share price has been volatile in the past and may decline in the future.

Our common stock has experienced significant market price and volume fluctuations in the past and may experience significant market price and volume fluctuations in the future in response to factors such as the following, some of which are beyond our control:

·   quarterly variations in our operating results;

·   operating results that vary from the expectations of securities analysts and investors;

·   changes in expectations as to our future financial performance, including financial estimates by securities analysts and investors;

·   announcements of technological innovations or new products by us or our competitors;

·   announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments;

·   changes in the status of our intellectual property rights;

·   announcements by third parties of significant claims or proceedings against us;

·   additions or departures of key personnel;

·   future sales of our common shares; and

·   stock market price and volume fluctuations.

Stock markets often experience extreme price and volume fluctuations. Market fluctuations, as well as general political and economic conditions, such as a recession or interest rate or currency rate fluctuations or political events or hostilities in or surrounding the United States, could adversely affect the market price of our common stock.

Future sales of our common stock in the public market could lower our stock price, and conversion of our warrants and any additional capital raised by us may dilute your ownership in us.

We may sell additional shares of common stock in subsequent offerings. In addition, holders of warrants to purchase our common stock will, most likely, exercise their warrants to purchase shares of our common stock after this registration statement is declared effective. We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock, including shares issued in connection with the exercise of the warrants, or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock.

Shares eligible for public sale in the future could decrease the price of our common stock and reduce our future ability to raise capital.

Sales of substantial amounts of our common stock in the public market could decrease the prevailing market price of our common stock, which would have an adverse affect on our ability to raise equity capital in the future.

Because Lighting Science’s Stock Price Is Volatile, It Can Be Difficult For Stockholders To Predict The Value Of Their Shares At Any Given Time.

The price of our stock can be volatile, which makes it difficult for stockholders to predict the value of their shares or buy or sell shares at any given time. In the last two fiscal years, the price of our common stock has ranged from $0.24 to $2.55. A variety of factors may affect the market price of our common stock including, but not limited to, results of research and development; corporate partnerships; technological innovations by Lighting Science Group or competitors; changes in laws and government regulations; developments concerning proprietary rights, including patents and litigation matters; public perception relating to the commercial value or safety of any of our products; and general stock market conditions.

Our common stock is currently traded on the OTCBB. Trading in our common stock is sporadic, and days may from time to time pass without any reported trades. If limited trading in our common stock continues, it may remain difficult for stockholders to sell their shares in the public market. This limited trading also could decrease or eliminate our ability to raise additional funds through issuances of its securities.

There Is No Assurance Of An Established Public Trading Market For Our Securities.

Although our common stock is quoted in the OTCBB, a regular trading market for the securities may not be sustained in the future. The OTCBB is an inter-dealer, over-the-counter market that provides significantly less liquidity than the Nasdaq stock market. Quotes for stocks listed in the OTCBB are not listed in the financial sections of newspapers and newspapers generally have very little coverage of stocks quoted solely in the OTCBB. Accordingly, prices for and coverage of securities quoted solely in the OTCBB may be difficult to obtain. In addition, stock quoted solely in the OTCBB tend to have a limited number of market makers and a larger spread between the bid and ask prices than those listed on the NYSE, AMEX or Nasdaq. All of these factors may cause holders of our common stock to be unable to resell their securities at or near their original offering price or at any price. Market prices for our common stock will be influenced by a number of factors, including:

·   changes in interest rates;

·   competitive developments, including announcements by competitors of new products or services or significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments;

·   variations in quarterly operating results;

·   changes in financial estimates by securities analysts;

·   the depth and liquidity of the market for our common stock, and

·   general economic and other national conditions.

Our Common Stock May Be Considered A “Penny Stock” And May Be Difficult to Sell.

The SEC regulations generally define a “penny stock” to be an equity security that has a market price of less than $5.00 per share or an exercise price of less than $5.00 per share, subject to specific exemptions. The market price of our common stock is less than $5.00 per share and, therefore, it may be designated as a “penny stock” according to SEC rules. This designation requires any broker or dealer selling these securities to disclose certain information concerning the transaction, obtain a written agreement from the purchaser and determine that the purchaser is reasonably suitable to purchase the securities. These rules may restrict the ability of brokers or dealers to sell our common stock and may affect the ability of investors to sell their shares.

Because Lighting Science Group Has Never Paid Dividends On Its Common Stock And Has No Plans To Do, So, The Only Return On Your Investment Will Come From Any Increase In The Value Of The Common Stock.

Since beginning our current business, we have not paid cash dividends on the common stock and do not intend to pay cash dividends in the foreseeable future due to our limited funds for operations. We currently intend to retain future earnings, if any, to finance operations and expand our business and, therefore, do not expect to pay any dividends in the foreseeable future. Therefore, any return on your investment would come only from an increase in the value of the stock.

Our Directors And Management Will Collectively Control Approximately 23% Of Our Outstanding Common Stock.

Immediately after this offering, our directors and executive officers and their affiliates will collectively control approximately 23% of our outstanding common stock. As a result, these stockholders, if they act together, will be able to influence our management and affairs and all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. You and other stockholders may have a limited influence over these actions. This concentration of ownership may have the effect of delaying or preventing a change in control of our company and might adversely affect the market price of our common stock.

Because There Is A Potential For Future Dilution To Existing Stockholders, Their Percentage Ownership And Control Over Company Matters Could Be Reduced.

Currently, we are authorized to issue up to 495,000,000 shares of our common stock. As of January 31, 2006, there were issued and outstanding 55,374,591 shares of our common stock and we may be obligated to issue up to 20,022,597 shares of our common stock to the holders of our outstanding preferred stock, warrants and stock options. The authorized but unissued shares may be issued by us in such transactions and at such times as our board of directors considers appropriate, whether in public or private offerings, as stock splits or dividends or in connection with mergers and acquisitions or otherwise. Any such issuance that is not made solely to then-existing stockholders proportionate to their interests (as in a stock dividend or stock split) will result in dilution to each stockholder by reducing his or her percentage ownership of the total outstanding shares.

We Could Be The Subject Of Securities Class Action Litigation Due To Future Stock Price Volatility.

The stock market in general, and market prices for the securities of technology companies like ours in particular, recently have experienced extreme volatility that often has been unrelated to the operating performance of the underlying companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. Recently, when the market price of a stock has been volatile, holders of that stock have often instituted securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, our defense of the lawsuit could be costly and divert the time and attention of our management.

Substantial Sales Of Our Common Stock Could Cause Our Stock Price To Decline.

Sales of a substantial number of shares of common stock after this offering, or the perception that sales could occur, could adversely affect the market price of our common stock. On completion of this offering, we will have up to 71,841,188 shares of common stock outstanding, 680,000 shares underlying outstanding stock options and 2,876,000 shares subject to outstanding warrants. In general, the 30,727,420 shares sold in this offering will be freely tradable without restriction or further registration under the federal securities laws.

Anti-Takeover Provisions In Our Charter Documents And Delaware Law Could Prevent Or Delay A Change In Control Of Our Company.

Provisions of our certificate of incorporation and by-laws may discourage, delay or prevent a merger, acquisition or change of control that a stockholder may consider favorable. These provisions include the ability to issue “blank check” preferred stock. The existence of this provision could limit the price that investors might be willing to pay in the future for shares of our common stock.

Provisions of Delaware law may also discourage, delay or prevent someone from acquiring or merging with our company or obtaining control of our company.

CAUTIONARY STATEMENTS REGARDING FORWARD LOOKING STATEMENTS

This prospectus contains certain forward-looking statements regarding management’s plans and objectives for future operations including plans and objectives relating to our planned marketing efforts and future economic performance. The forward-looking statements and associated risks set forth in this prospectus include or relate to, among other things, (a) our projected sales and profitability, (b) our growth strategies, (c) anticipated trends in our industry, (d) our ability to obtain and retain sufficient capital for future operations, and (e) our anticipated needs for working capital. These statements may be found under “Plan of Operation” and “Description of Business,” as well as in this prospectus generally. Actual events or results may differ materially from those discussed in forward-looking statements as a result of various factors, including, without limitation, the risks outlined under “Risk Factors” and matters described in this prospectus generally. In light of these risks and uncertainties, there can be no assurance that the forward-looking statements contained in this prospectus will in fact occur.

The forward-looking statements herein are based on current expectations that involve a number of risks and uncertainties. Such forward-looking statements are based on assumptions that we will be able to make strategic acquisitions on a timely basis, that we will retain our or an acquiree’s customers, that there will be no material adverse competitive or technological change in conditions in our business, that demand for our products will significantly increase, that our management will remain employed as such, that our forecasts accurately anticipate market demand, and that there will be no material adverse change in our operations or business or in governmental regulations affecting us or our manufacturers and/or suppliers. The foregoing assumptions are based on judgments with respect to, among other things, future economic, competitive and market conditions, and future business decisions, all of which are difficult or impossible to predict accurately and many of which are beyond our control. Accordingly, although we believe that the assumptions underlying the forward-looking statements are reasonable, any such assumption could prove to be inaccurate and therefore there can be no assurance that the results contemplated in forward-looking statements will be realized. In addition, as disclosed elsewhere in the “Risk Factors” section of this prospectus, there are a number of other risks inherent in our business and operations which could cause our operating results to vary markedly and adversely from prior results or the results contemplated by the forward-looking statements. Growth in absolute and relative amounts of cost of goods sold and selling, general and administrative expenses or the occurrence of extraordinary events could cause actual results to vary materially from the results contemplated by the forward-looking statements. Management decisions, including budgeting, are subjective in many respects and periodic revisions must be made to reflect actual conditions and business developments, the impact of which may cause us to alter marketing, capital investment and other expenditures, which may also materially adversely affect our results of operations. In light of significant uncertainties inherent in the forward-looking information included in this prospectus, the inclusion of such information should not be regarded as a representation by us or any other person that our objectives or plans will be achieved.

Some of the information in this prospectus contains forward-looking statements that involve substantial risks and uncertainties. Any statement in this prospectus and in the documents incorporated by reference into this prospectus that is not a statement of an historical fact constitutes a “forward-looking statement.” Further, when we use the words “may,” “expect,” “anticipate,” “plan,” “believe,” “seek,” “estimate,” “internal,” and similar words, we intend to identify statements and expressions that may be forward-looking statements. We believe it is important to communicate certain of our expectations to our investors. Forward-looking statements are not guarantees of future performance. They involve risks, uncertainties and assumptions that could cause our future results to differ materially from those expressed in any forward-looking statements. Many factors are beyond our ability to control or predict. You are accordingly cautioned not to place undue reliance on such forward-looking statements. Important factors that may cause our actual results to differ from such forward-looking statements include, but are not limited to, the risk factors discussed above. Before you invest in our common stock, you should be aware that the occurrence of any of the events described under “Risk Factors” in this prospectus could have a material adverse effect on our business, financial condition and results of operation. In such a case, the trading price of our common stock could decline and you could lose all or part of your investment.

USE OF PROCEEDS

We will not receive any proceeds from the sale of the shares offered pursuant to this prospectus. All of the proceeds will be payable solely to the selling stockholders. We will, however, receive the proceeds from the exercise of the warrants issued to the selling stockholders, if and when they are exercised, to the extent they are not exercised under a cashless exercise. The terms of the warrant agreement permit the warrants to be exercised without tendering cash at a value based on market value of our common stock under certain conditions. A cashless exercise will result in less shares being issued than under a cash exercise. We anticipate that the net proceeds from the exercise of the warrants, if any, will be used for working capital and general corporate purposes. The actual allocation of proceeds realized from the exercise of these warrants will depend upon the amount and timing of such exercises, our operating revenues/losses and cash position at such time and our working capital requirements. There can be no assurances that any of the outstanding warrants will be exercised.

The selling stockholders will pay any expenses customarily borne by selling stockholders (including discounts, commissions and fees and expenses of counsel relating to the sale of their securities, to the extent not required to be paid by us). We will bear all other costs, fees and expenses incurred in effecting the registration of the shares covered by this prospectus, including, but not limited to, all registration and filing fees, listing fees and expenses of our counsel and our accountants.

DESCRIPTION OF BUSINESS

Lighting Science Group is a Delaware corporation incorporated on June 16,1988. On December 23, 2004, The Phoenix Group Corporation, our predecessor entity, announced its decision to change its name to Lighting Science Group Corporation by means of a parent/subsidiary merger with its wholly-owned subsidiary, Lighting Science, Inc. Pursuant to a resolution approved by the board of directors, The Phoenix Group Corporation filed a certificate of merger with the office of the Secretary of State of Delaware on December 23, 2004 to complete the merger of Lighting Science, Inc. with and into The Phoenix Group Corporation and to change the name. Lighting Science Group began conducting its operations under the name Lighting Science Group Corporation on January 1, 2005.

On or about August 20, 2002, we filed a voluntary petition seeking debtor-in-possession status for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware. The case was subsequently transferred to the U.S. Bankruptcy Court for the Northern District of Texas - Ft. Worth Division bankruptcy court. The bankruptcy court granted the requested status. During the summer of 2003, we filed a Disclosure Statement and Plan of Reorganization that was confirmed by the bankruptcy court on September 16, 2003 with an effective date of September 26, 2003. Under the terms of the plan of reorganization, the holder of the Series A Preferred Stock, Match, Inc., a company controlled by our Chief Executive Officer, Ronald E. Lusk, agreed to waive its rights, including its voting and conversion rights, and the creditors of Lighting Science Group received an aggregate of approximately 51% of the common stock of the restructured entity in exchange for notes, accounts payable, and other forms of debt held at the time of the filing of the petition. This feature of the plan of reorganization - the exchange of debt for greater than 50% of the equity in the restructured entity - qualified us to utilize the reporting guidelines of the “Fresh Start” accounting rules contained in Statement of Position 90-7.

On June 1, 2004, we acquired 100% of the outstanding common stock of Lighting Science, Inc., a corporation that developed and owned certain intellectual property related to the design, development and power management of lighting products utilizing light emitting diodes as a source of light. As of the date of this prospectus, we continue with our plans to develop and sell products based upon the intellectual property acquired in this acquisition.

Market Overview

The global lighting market has annual sales exceeding $40 billion, with the U.S. market alone contributing $12 billion to $15 billion annually.¹ More importantly, the lighting market consumes over 20% of the world’s energy on an annual basis.² This is the target market that management believes will evolve to solid state lighting.

With our acquisition of Lighting Science, Inc., we entered the field of solid state lighting. Light emitting diode technology has been in use since 1962, but until recently was used only in small electronic devices. Unlike incandescent bulbs, which produce the full spectrum of light in a spherical pattern, LEDs emit a monochromatic focused beam that is highly directional. For many applications, such as indicators or switch illuminators, this is not a problem. But it took development of multi-chip arrays, high-flux LED chips, and specialized phosphors to achieve the effect of an incandescent bulb.

As a result of these recent innovations, many designers have begun to focus their attention on LEDs as a new source of product for traditional lighting needs. LED-based lighting is now available in a variety of light bases and sizes, most of which are suitable only for specialty lighting. LED-based lighting is rugged, durable, and visible in daylight. Its life span, which far exceeds that of incandescent bulbs, is an advantage for high volume users of light bulbs who are faced with high-energy consumption and recurring maintenance obligations. These maintenance obligations can have legal ramifications as well as aesthetic implications.

Industry studies have predicted that LED-based lighting will replace over 40% of incandescent lighting applications by 2025.³ It is estimated that by the same year solid state lighting could reduce the global amount of electricity used for lighting by 50%.⁴ Lighting Science Group believes that no other use of electricity can offer such a large energy-savings potential.

Increased investment by the manufacturers of LEDs over the past decade has resulted in performance enhancements and cost reductions that have exceeded expectations. Since their introduction, LED prices have fallen while performance has grown. This pattern caused retired Agilent scientist Roland Haitz to measure the change and to develop “Haitz’s Law” (similar to Moore’s Law in the computer chip industry) which holds that each decade since the first LED appeared in 1962, prices have fallen by a factor of 10 while performance has grown by a factor of 20.⁵

While manufacturers of LEDs have made great strides, the enabling technologies such as power conversion and thermal management have not kept pace. These technologies in the LED industry can be equated to software applications in the computer chip industry. But while software development takes advantage of each hardware enhancement, the technologies necessary to derive the greatest performance from LEDs have lagged. Consequently, the existing gap between the advancements in LED technology and their incorporation into general illumination systems has widened over the past five years.

Competitive Advantages

Through the development of our Optimized Digital Lighting technology, we believe that we have begun to close the gap between the theoretical performance capability of today’s LEDs and the level of their performance in the current generation of general illumination products. With our enabling technologies, we believe that we have positioned ourselves at the forefront of the emerging solid state lighting industry and will be able to compete in the marketplace, for the following reasons:

·   Digital lighting expertise is our core competency. We have and will continue to generate important intellectual properties:

·   Patent pending digital lighting engineering design

·   Patent pending bulb design appearance

·   Patent pending manufacturing process

·   Compared with 65-watt incandescent bulbs, Optimized Digital Lighting bulbs currently reduce energy use by up to 85% and have a useful life that is up to 50 times longer (approximately 50,000 hours).

·   Several factors contribute to the benefits produced by our ODL technology:

·   Our patented and patent pending technology allows retail pricing that is both affordable and provides a fast payback through reduced energy consumption maintenance costs in most applications.

·   Optimized Digital Lighting products have added functionality - they are dimmable and reach their full operating level instantly unlike most fluorescent bulbs.

·   Development of additional Optimized Digital Lighting products is ongoing. The product development team is bolstered by a scientific advisory board with expertise in many disciplines of the lighting industry.

Products/Distribution

Lighting Science Group has begun to introduce its Optimized Digital Lighting products through traditional commercial and retail distribution channels and on a direct basis through its sales force, as well as through shared savings plans with larger commercial and municipal customers. Our near-term product portfolio consists of the following:

·   Flashlights - We have developed a flashlight that provides a high candlepower output across a broader beam angle than is typical of existing LED based flashlights and can be made available at a lower price point due to the manufacturing efficiencies created by Lighting Science Group’s proprietary design.

·   Cabinet Lighting - We have a developed a small lamp, called the Puck Light, that replaces existing halogen incandescent lamps. Aside from energy savings and much longer life, the Puck Light is safer for usage inside furniture because it operates at a much lower temperature.

·   Floodlights - We are developing a second generation floodlight prototype that equals or exceeds existing PAR 30 65-watt floodlights sold by incumbent lighting manufacturers in terms of the amount of illumination (foot candles) measured at the surface to be illuminated across a beam angle of 50º. We plan initial shipments of the floodlight in the first half of 2006.

·   Parking Garage Lighting -We have developed a low bay form factor light that we believe is competitive with conventional lights used in parking garages.

·   Outdoor Lighting - We are currently prototyping a form factor street light which we believe will be competitive with 150 watt - 250 watt conventional street lights on poles 30 feet or less in height. Other forms, in higher wattage equivalents (e.g., 400 watts) are planned.

Operations

Following the acquisition of Lighting Science, Inc., we have continued with our plans to develop and sell products based upon the acquired intellectual property. Staff was added to support the development process. Additionally, we have begun to work with major international design, engineering and manufacturing companies to support the development of our products and the transition of such products into the manufacturing process.

In order to minimize our investment in plant and equipment and enable us to focus on research and development, our manufacturing strategy is to outsource the manufacture of our Optimized Digital Lighting products, and, therefore, we do not own or operate a manufacturing facility. We currently partner with a small number of contract manufacturers to manufacture our products at plants in various locations throughout the world. These manufacturers supply all necessary raw materials (other than certain critical components such as LEDs, which we procure directly), provide all necessary facilities and labor to manufacture our products, and stock and arrange for transport of our finished goods, generally by ship, to our distributors and customers.

We currently have multiple sources of supply for the LEDs used in the assembly of our lighting products. We currently buy LEDs from two domestic manufacturers and two foreign manufacturers. All suppliers currently have adequate capacity to provide sufficient quantities of LEDs to meet our forecasted needs. Our lighting products incorporate a proprietary power supply module. These modules are fabricated by two manufacturers, each of which has adequate capacity to produce estimated quantities of power modules to meet our forecasted needs. One domestic supplier and several foreign suppliers provide microelectronic components for the various lighting products. We have no sole source supply for any of the assemblies required for the manufacture of our lighting products.

Employees

As of January 31, 2006, we have 15 full-time employees. We believe that our relationship with our employees is good. None of our employees is represented by an employee union.

PLAN OF OPERATION

As of the date of this report, we continue to operate as a development stage company, not having had appreciable revenue during our last fiscal year or the first month of 2006. Accordingly, our plan of operation for the next twelve months is set forth below.

Business Overview

With our acquisition of certain intellectual property rights on June 1, 2004, we have entered the field of solid-state lighting. Light emitting diode technology has been in use since 1962, but until recently was used only in small electronic devices. Unlike incandescent bulbs, which produce the full spectrum of light in a spherical pattern, LEDs emit a monochromatic focused beam that is highly directional. For many applications, such as indicators or switch illuminators, this is not a problem. But it took development of multi-chip arrays, high-flux LED chips, and specialized phosphors to achieve the effect of an incandescent bulb.

Through the development of our Optimized Digital Lighting technology, we believe that we have begun to close the gap between the theoretical performance capability of today’s LEDs and the level of their performance in the current generation of general illumination products. With our enabling technologies, Lighting Science Group believes that it has positioned itself at the forefront of the emerging solid state lighting industry and will be able to compete in the marketplace.

Strategy

We are beginning to introduce our Optimized Digital Lighting products through traditional commercial and retail distribution channels and on a direct basis through our sales force, as well as through shared savings plans with larger commercial and municipal customers.

We have developed the Shared Savings Program^SM that allows customers to partner with us to deploy our ODL products without any upfront capital expenditures while benefiting from the significant energy savings provided by our ODL products. Our lighting products pay for themselves in energy savings, which are shared between us and the customer. The Shared Savings Program is focused on municipalities and companies with significant outdoor lighting requirements. The program requires an investment by us in product and labor to install the lights in a city or a municipality. We believe that we will be able to secure the financing for such installations through traditional commercial lending institutions.

We will also focus on the wholesale and retail distribution of our ODL technology and its general illumination products. These products include existing and planned product lines of floodlights, spotlights, and additional general illumination products that are under development. We are exploring opportunities to sell our ODL products through traditional mass market retailers as well as domestic and international lighting distributors.

Our distribution strategy with respect to our near term products is as follows:

·   Flashlights - Our flashlight is currently available on the website of the Home Depot, a big box retailer, and is currently under evaluation by Home Depot for sale in its stores. We are aggressively marketing this product to other retailers as well as through distributors.

·   Cabinet Lighting - We have delivered an initial order of puck lights to a major Las Vegas casino and we intend to aggressively market this product to furniture manufacturers and to potential users in the hotel and recreation industries.

·   Floodlights - We intend to market this light through warehouse-style and other big-box retailers, lighting distributors, under our Shared Savings Program and on a direct basis in certain industries. We began to prototype an industry standard form factor PAR 30 floodlight in the third quarter of 2005, and we plan to sell this product via big-box retailers in addition to marketing it directly to the hospitality and facility management industries. 

·   Parking Garage Lighting -We have established direct contact with major parking garage operators across the country and these parking garage lights will be made available for outright sales, as well as under the Shared Savings Program. In conjunction therewith, we have formed an alliance with Amtech Lighting Services (see below) to install our parking garage lights and fixtures in facilities that Amtech services. On December 14, 2005, we announced our first contract to supply ODL low bay lighting to an existing parking garage in the Dallas, Texas area under the Shared Savings Program.

·   Outdoor Lighting - We expect to make streetlights available under our Shared Savings Program either directly or via Energy Service Company (ESCO) partners.

Strategic Alliances

Agreement with Amtech Lighting Services

On September 8, 2005, we announced that we entered into an alliance with Amtech Lighting Services, a subsidiary of ABM Industries Incorporated, a multi-national facilities services leader, to install our ODL low bay lights and fixtures in facilities that ABM services. The low bay product is designed for widespread, high volume use in parking garages and other applications that require high efficiency, long lasting light.

Under the alliance, Amtech Lighting Services is marketing our ODL products to its customers through our Shared Savings Program. As part of the Amtech Lighting Services/Lighting Science Group alliance, Amtech will undertake installation and maintenance of the ODL parking garage lights on behalf of its customers.

More specifically, Amtech Lighting Services is in the initial phase of introducing our ODL products to some of its energy-conscious customers who operate 35,000 locations nationwide, and is beginning to test and install ODL fixtures at some of the 1,700 garages it leases or manages through Ampco System Parking, a subsidiary of ABM Industries.

Agreement with Giuliani Capital Advisors

On February 15, 2005, we entered into a letter agreement with Giuliani Capital Advisors LLC, or GCA, to engage GCA to provide financial advisory services to us and a yet to be formed entity. On May 4, 2005, we entered into an agreement with GCA to form the joint venture. The intent of the joint venture is to own parking garage lights and streetlights and related lighting infrastructure targeting municipalities, public utility corporations, universities, large mall owners, parking lot owners, and other organizations as partners/customers. The services GCA has agreed to provide include the following:

·   Assist us on an exclusive basis to raise capital for the joint venture;

·   Evaluate financial and organization structures on a non-exclusive basis relating to different market opportunities that may be presented to us;

·   Advise us on sources of debt and equity capital available to fund the joint venture;

·   Assist management in coordination between advisors and debt/equity underwriters;

·   Assist us in arranging meetings with various governmental entities and utilities, both domestic and international, to acquire light poles and related infrastructure; and

·   If requested, assist Lighting Science Group in raising equity or debt financing for other Company projects.

Consulting Contract with Equity Group, Inc.

On February 10, 2005, we entered into a consulting contract with Equity Group, Inc. to provide financial public relations and investor relations on behalf of Lighting Science Group for a fee of $5,000 per month during the term of the contract.

Liquidity and Capital Resources

On May 12, 2005, Lighting Science Group entered into a Securities Purchase Agreement with investors for the private placement of its preferred stock pursuant to which the investors purchased 2,260,966 shares of the preferred stock at $3.20 per share for an aggregate purchase price of approximately $7.2 million. The net proceeds to Lighting Science Group were approximately $6.5 million, including $276,000 of certain officer and director loans outstanding at the time, which were also converted to preferred stock. These funds are being used for working capital purposes.

We have embarked upon an aggressive design and development program to begin to bring products to market during 2005 and 2006. If, as management believes, we are successful in developing viable products, additional capital may be needed to fund the manufacturing process to generate finished goods. In the event orders are received from established retailers and distributors of lighting products, management believes that traditional lending sources will be available to provide a portion of the capital needed to cover the manufacturing and receivables cycles. However, we may still be required to raise additional capital to meet our obligations.

Our strategy includes the outsourcing of manufacturing operations. Accordingly, there are no significant investments in plant or equipment expected in the next 12 months. Additionally, the startup of product deliveries will require us to make additions to our operations and administrative management teams. However, such personnel additions are not expected to result in substantial increases in employee headcount.

DESCRIPTION OF PROPERTY

Our corporate headquarters are located in Dallas, Texas. We occupy excess office space that is leased by an institutional shareholder of Lighting Science Group. The shareholder previously served as a financial advisor to Lighting Science Group. The shareholder allowed us to occupy the office space during the term of the financial services agreement on a rent free basis. Upon termination of the financial services agreement on September 29, 2005, we began to pay the shareholder rent on a month to month basis at the rate of $10,000 per month. We also have leased facilities in Sunrise, Florida for our research and development activities for a period of 15 months beginning on November 1, 2005. The agreement provides rental payments averaging approximately $2,400 per month. We also lease space in Hong Kong and storage space in Dallas, Texas on a month-to-month basis at a total rate of approximately $650 per month.

The note was issued by Lighting Science, Inc. to the trust in exchange for the assignment of certain provisional patents and intellectual property that formed the basis for the acquisition of Lighting Science, Inc. by Lighting Science Group. The note is in the principal amount of $200,000, does not bear interest and is payable in 36 equal monthly installments beginning on the fifteenth day of the month following the first full month that we begin generating revenue in the amount of $10,000 or more, as determined in accordance with generally accepted accounting principles.

We made advance payments to the trust on this note in the amounts of $25,000 in October 2004 and $25,000 in May 2005. This note provides for no interest. However, under generally accepted accounting principles, an amount of interest should have been imputed. Such amount was not material.

Lighting Science Group Corporation generated revenue in excess of $10,000 in August of 2005. Accordingly, we are now obligated and will begin making regular installment payments on the note commencing in June 2006.  The company has estimated June 2006 as the date when regular installment payments will begin, based on the number of months of regular installments that were pre-paid in 2004 and 2005 as noted above.

Note Payable to Trust of Stockholder and Chairman Ronald E. Lusk / Exchange of Note and Series A Preferred Stock for Common Stock

We were previously obligated under the terms of a line of credit agreement to Match, Inc. outstanding in the amount of $1,851,299 principal balance and $341,226 in accrued interest at March 31, 2005. Ronald E. Lusk, Chairman of Lighting Science Group, controls Match, Inc. as Trustee of the Ronald E. Lusk Revocable Trust. The line of credit agreement with Match, Inc. was available up to a limit of $2 million, bore interest at prime plus 1% on the note balance and prime plus 2% on any unpaid interest amounts, was due on demand and was unsecured.

On July 25, 1994, Lighting Science Group sold, for proceeds of $2 million, 533,333 shares of Series A Preferred Stock with cumulative dividends of $0.30 per annum for each share and conversion rights to common stock at a price of $3.75 per share. Under the terms of the Disclosure Statement and Plan of Reorganization under which Lighting Science Group emerged from bankruptcy, Match, Inc., the holder of the Series A Preferred Stock, waived such rights, including voting and conversion rights. No dividends had been paid with respect to this class of stock. At March 31, 2005, the cumulative unpaid dividend with respect to the preferred stock was $1,670,685. Thus, the total liquidation preference of the preferred stock was $3,670,685 as of March 31, 2005.

In contemplation of our private placement of 6% Convertible Preferred Stock that was completed in May 2005,our financial advisor and its investment-banking representative had both advised that the outstanding debt and preferred stock would preclude us from successfully completing the financing transaction and should be eliminated through conversion into common stock. The board of directors concurred with this assessment, and accordingly, a special committee of independent directors consisting of Directors Robert E. Bachman, Donald R. Harkleroad, and Robert L. Woodson, III was formed on March 14, 2005 to negotiate with Mr. Lusk to exchange the preferred stock and the amount owed on the debt for shares of common stock.

The special committee took note of the fact that for the month of March 2005, the closing prices for the common stock had ranged between $1.48 and $1.90 per share. The proposal submitted by Mr. Lusk offered to set the exchange ratio at $1.725 per share, which represented the five-day average closing price as of March 15, 2005. Mr. Lusk also proposed to reduce the amount of the accrued interest on the line of credit with Match, Inc. by $250,000. Thus, the number of shares for which the preferred stock and the cumulative dividend would be exchanged was equal to 2,127,933 ($3,670,685 / $1.725) under the proposal presented by Mr. Lusk. Using the same conversion price of $1.725 proposed by Mr. Lusk, the total of $1,942,525 ($2,192,525 - $250,000) due on the line of credit would be convertible into 1,126,101 shares of common stock of Lighting Science Group. The committee also noted that the trading range for the stock at the end of the month of March was closer to the lower end of the range ($1.48) at the time that the analysis was being completed. The special committee reported the results of its analysis to the board.

The board of directors (with Mr. Lusk abstaining and one director absent) reviewed the analysis prepared by the special committee. Based upon the exchange ratio of $1.725 per share offered by Mr. Lusk with respect to both the exchange of the preferred stock and the debt, as well as the proposal by Mr. Lusk to reduce the accrued interest on the line of credit by $250,000, the board concluded that the offer was fair to Lighting Science Group and voted to approve the transactions contained in the proposal from Mr. Lusk. A total of 3,254,034 shares of common stock were issued in exchange for the Series A Preferred Stock and the amount due under the line of credit agreement on May 5, 2005.

Loan from Stockholder and Chairman Ronald E. Lusk

On November 25, 2003 Ronald E. Lusk, the chairman of Lighting Science Group, advanced $50,000 to Lighting Science Group for purposes of meeting general and administrative expenses. The loan provided for interest at a rate of prime plus 1%. Mr. Lusk elected to forego any interest that was otherwise due with respect to the loan. No interest on the loan had previously been recorded by Lighting Science Group. Any such interest would not have been material. During 2004, Mr. Lusk advanced Lighting Science Group an additional $29,541 for general corporate purposes. During the third quarter of 2004, Lighting Science Group repaid the outstanding balances on these advances.

Office Lease with Stockholder and Director Daryl N. Snadon

Until November 2004, we leased our executive offices from a partnership consisting of Daryl N. Snadon, a member of our board of directors, and two other individuals. Our former, long-term lease with this partnership was terminated in connection with our bankruptcy. When we emerged from bankruptcy, we entered into an oral lease agreement with Mr. Snadon’s partnership to lease our executive offices on a month-to-month basis. Under the agreement, the landlord agreed to accept shares of our common stock in lieu of cash payments for rent. To date, all amounts owed by us under our lease have been paid by issuing shares of common stock to the members of the partnership, including 682,684 shares to Mr. Snadon. No further commitment remains under this agreement, and no additional stock is required to be issued.

Service Agreement with Shareholder

On November 13, 2004, we moved our executive offices from Richardson, Texas to Dallas, Texas where we occupy excess office space that is leased by an institutional shareholder of Lighting Science Group who previously served as a financial adviser. The shareholder allowed us to occupy the space on a rent-free basis during the terms of the financial services agreement. Such free rent was not material. Upon termination of the financial services agreement on September 29, 2005, we began to pay the shareholder rent at the rate of $10,000 per month. For services rendered as financial advisor, we issued a warrant to purchase 63,984 shares of our common stock in conjunction with our private placement of preferred shares on May 12, 2005.

Employment Agreements

We entered into three-year employment agreements with each of Messrs. Lusk, Poss and Hartman, and Ms. Fuller during fiscal years 1999, 2000, 2001 and 2002, respectively. Ms. Fuller resigned from Lighting Science Group in May 2005 and is no longer an employee. On June 1, 2004, we entered into a similar agreement with Mr. Maxik upon the acquisition of Lighting Science, Inc. Upon completion of the initial three-year terms, each agreement is automatically renewed for successive one-year periods. We may terminate any agreement as of the renewal date of such agreement upon 90 days advance written notice to the subject employee. In addition, we may terminate an agreement upon the death or disability of the employee or upon just cause. In the event an agreement is terminated by us without cause or by the employee upon a change in control of Lighting Science Group, we are obligated to pay the compensation that the employee would otherwise be entitled to receive had the agreement not been terminated.

Under their agreements, Messrs. Lusk, Maxik and Poss were entitled to receive a base annual salary of $250,000. In addition, upon execution of the agreements, Mr. Lusk was issued 31,250 shares of common stock in March 2000, Mr. Poss was issued 312,500 shares of common stock in May 2004 and Mr. Maxik was issued 156,250 shares of common stock in August 2004. Under Mr. Hartman’s agreement, he was entitled to receive a base annual salary of $200,000. Upon execution of his agreement, Mr. Hartman was issued 31,250 shares of common stock in December 2000. Under Ms. Fuller’s agreement, she was entitled to receive a base annual salary of $100,000. Upon execution of her agreement, Ms. Fuller was issued 37,500 shares of common stock in March 2002. Previously, under all of the employment agreements, certain of the compensation owed to the employees was payable by us through the issuance of shares of Lighting Science Group’s common stock. Such compensation was not paid in the amounts set forth in the employment agreements and is no longer due or payable. We did pay stay bonuses in recognition of the work performed to allow us to emerge from bankruptcy, pursuant to which Mr. Lusk was issued 555,502 shares of common stock, Mr. Poss was issued 365,269 shares of common stock, Mr. Hartman was issued 400,289 shares of common stock, and Ms. Fuller was issued 619,479 shares of common stock. The employment agreements of Messrs. Lusk, Poss and Hartman were amended effective May 29, 2004, to remove the provision regarding the payment of compensation through the issuance of shares of our common stock and the base salaries of certain of these officers as set forth in their employment agreements were amended, as follows: Mr. Poss, $90,000, and Mr. Hartman, $150,000. Pursuant to the terms of his employment agreement, Mr. Maxik is still entitled to elect to receive his compensation in shares of our common stock.

On October 12, 2004, we hired and entered into three year employment and change in control agreements with Mr. Stan T. Waldrop and Mr. Philip R. Lacerte to serve as Lighting Science Group’s President and Executive Vice President, respectively. The terms of the employment agreements provided for annual compensation of $225,000. However, Mr. Waldrop and Mr. Lacerte elected to defer the first year of salary so that additional funds could be committed to our product development. The terms of the change in control agreements provided that in the event of a change in control, as defined in the agreement, a single sum cash payment equal to two and one-half (2-1/2) times the executive's average annual compensation (including base salary and bonuses) paid to him in cash during the thirty-six (36) month period immediately preceding the date on which the change in control occurred shall be paid to each of Mr. Waldrop and Mr. Lacerte. Each executive was also granted the right to sell to Lighting Science Group all or any portion of the shares of Company stock granted to him under his employment agreement or obtained through the exercise of Company-granted stock options which he owned (or to which he was entitled under an outstanding stock option or other agreement) as of the date of the change in control at a price equal to 105% of the per share price (or the equivalent thereof) paid in the transaction causing the change in control. A similar change in control agreement was executed with Mr. Lusk on the same date.

On October 4, 2005 Mr. Lacerte resigned as the our Executive Vice President effective as of that date. In connection with his resignation and in consideration for Lighting Science Group agreeing to release him from his obligations under his employment and change in control agreements, except for certain sections within each agreement, Mr. Lacerte agreed to transfer and deliver to the us 100,000 shares of our common stock, $.001 par value per share. Effective October 17, 2005, the employment and change in control agreement with Mr. Waldrop was terminated as a result of Mr. Waldrop’s resignation as Lighting Science Group’s President, except for certain sections thereof, which remain in full force and effect. Mr. Waldrop has agreed to provide consulting services to Lighting Science Group for six months following his resignation on an as-needed basis in exchange for 50,000 shares of our common stock, $.001 par value per share, which were issued as of October 18, 2005.

MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

Commencing on July 14, 2005, our common stock has been and continues to be quoted on the Over-the-Counter Bulletin Board, or the OTC Bulletin Board or the OTCBB, which is a quotation service administered by the National Association of Securities Dealers (NASD). Our trading symbol on the OTCBB is “LSGP.”

The OTCBB is a limited and sporadic trading market. The following table sets forth the range of high and low bid information of the common shares as reported on the OTCBB for the last two fiscal years and the subsequent period ended January 31, 2006. The price information available reflects inter-dealer prices, without retail mark-up, mark-down or commission and may not represent actual transactions.

As of January 31, 2006, there were 622 holders of record of our common stock, holding a total of 55,374,591 shares.

To date, Lighting Science Group has not paid cash dividends on its common stock and does not intend to pay cash dividends in the foreseeable future due to Lighting Science Group’s limited funds for operations. We currently intend to retain future earnings, if any, to finance operations and expand our business and, therefore, do not expect to pay any dividends in the foreseeable future. Therefore, any return on your investment would come only from an increase in the value of the stock.

On July 6, 2005, our board of directors adopted the Lighting Science Group Corporation 2005 Equity Based Incentive Compensation Plan and a proposal to implement this plan was approved at the annual shareholders’ meeting in August 2005. A total of 5,000,000 shares of common stock have been reserved under this plan. Prior to adoption of this plan, Lighting Science Group had no option or other equity based compensation plans.

In fiscal year 2005, a total of 730,000 stock options were granted to our employees and directors under the plan. An additional 50,000 stock options were granted to a consultant under the plan.

SELLING STOCKHOLDERS

The shares of common stock being offered by the selling stockholders are either shares of common stock (i) currently owned by the selling stockholder or (ii) issuable upon conversion of the 6% convertible preferred stock, par value $.001 per share held by purchasers of the preferred stock issued pursuant to a securities purchase agreement dated as of May 12, 2005 or (iii) issuable upon exercise of the warrants issued to those purchasers. For additional information regarding the preferred stock and the warrants, see “Summary -- The Private Placement” above. 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. Certain selling stockholders, as indicated next to their names, are members of our board of directors and senior management. Other associations, such as family relationships or affiliated trusts or businesses are also indicated.

The term “selling stockholders” includes the stockholders listed below and their respective transferees, assignees, pledgees, donees or other successors. The table below lists the selling stockholders and other information regarding the beneficial ownership of the shares of common stock by each of the selling stockholders. The second column lists the number of shares of common stock beneficially owned by each selling stockholder, based on the stockholder’s ownership of the preferred stock, warrants and other shares of common stock, as of May 12, 2005, assuming conversion of all preferred stock and exercise of the warrants held by each selling stockholder on that date, without regard to any limitations on conversions or exercise.

In accordance with the terms of registration rights agreements with the selling stockholders, this prospectus generally covers the resale of the sum of the (i) the number of shares of our common stock issuable upon conversion of the preferred stock as of the trading day immediately preceding the date the registration statement is initially filed with the SEC, (ii) the number of shares of common stock issuable upon exercise of the related warrants as of the trading day immediately preceding the date the registration statement is initially filed with the SEC, (iii) the shares of common stock issued and issuable in payment of dividends on the preferred stock, and upon any stock split, stock dividend, recapitalization or similar event with respect to such shares of common stock and any other securities issued in exchange of or replacement of such shares of common stock, (iv) the shares of common stock held by non-affiliated stockholders who have executed a lock-up agreement with Lighting Science Group and (v) shares of our common stock to be issued upon exercise of warrants held by Merriman Curhan Ford & Co., who acted as placement agent and MRM Capital LP, who acted as financial advisor in the private placement. Because the conversion price of the preferred stock and the exercise price of the warrants may be adjusted, the number of shares that will actually be issued may be more or less than the number of shares being offered by this prospectus.

The selling stockholders may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

DESCRIPTION OF SECURITIES

The following description is a summary of our capital stock and contains the material terms of the capital stock. Additional information can be found in our Certificate of Incorporation and Bylaws. Our certificate of incorporation authorizes the issuance of 495,000,000 shares of common stock, $0.001 par value per share. As of January 31, 2006, 55,374,591 shares of common stock were issued and outstanding.

Each holder of common stock is entitled to one vote per share of common stock standing in such holder’s name on the records on each matter submitted to a vote of Lighting Science Group stockholders, except as otherwise required by law. Holders of the common stock do not have cumulative voting rights. Holders of the common stock are entitled to equal dividends and distributions, per share, when, as and if declared by the board of directors from funds legally available. Holders of the common stock do not have preemptive rights to subscribe for any of our securities nor are any shares of the common stock redeemable or convertible into any of our other securities. If we liquidate, dissolve or wind up our business or affairs, our assets will be divided up pro-rata on a share-for-share basis among the holders of our common stock after creditors and preferred stockholders, if any, are paid.

Our certificate of incorporation authorizes the issuance of 5,000,000 shares of preferred stock, $0.001 par value per share, the designation and rights of which are to be determined by our board of directors. As of January 31, 2006, 2,260,966 shares of preferred stock were issued and outstanding.

The preferred stock may be issued from time to time in one or more series by resolution or resolutions of our board of directors. The resolution or resolutions of our board of directors may, to the full extent now or hereafter permitted by law and subject to the provisions of our certificate of incorporation, fix the voting powers, designations, preferences and relative, participating, option or other special rights, and qualifications, limitations or restrictions thereof, of the shares of such series. The authority of our board of directors with respect to each such series may include, but not be limited to, determinations of the following:

(a) the distinctive designation of such series, the number of shares that shall constitute such series, including any limitation on the authority to increase or decrease such number, and the stated value thereof, if any, if different from the par value thereof;

(b) the dividends, if any, payable either in cash, property or securities of Lighting Science Group, on such series, and the restrictions, limitations and conditions, if any, upon the payment of such dividends, whether any such dividends shall be cumulative or non-cumulative, the date or dates from which dividends, if declared, shall be payable, and the preference, if any, or relation that such dividends shall bear to the dividends payable on any shares of stock of any other class or any other series of this class;

(c) whether the shares of such series shall have voting power, in addition to any voting power provided by law and, if so, the terms of such voting power, which may be general or limited;

(d) the right, if any, of Lighting Science Group to redeem any or all shares of such series and, if so, the terms and conditions of such redemption;

(e) whether the shares of such series shall be subject to the operation of a retirement or sinking fund or funds and, if so, whether such retirement or sinking fund shall be cumulative or non-cumulative, the extent and manner in which any such retirement or sinking fund shall be applied to the purchase or redemption of the shares of such series for retirement or other corporate purposes and the terms and provisions relative to the operation thereof;

(f) whether the shares of such series shall be convertible into, or exchangeable for, shares of stock of any other class or any other series of this class or any other securities or assets and, if so, the price or prices or the rate or rates of conversion or exchange and the method, if any, of adjusting the same, and any other terms and conditions of conversion or exchange;

(g) the amount, if any, that the holders of the shares of such series shall be entitled to receive in case of a liquidation, dissolution or winding up of the corporation and the preference, if any, or relation which such amounts shall bear to the amounts payable on any shares of stock of any other class or any other series of this class;

(h) the limitations and restrictions, if any, to be effective while any shares of such series are outstanding upon the payment of dividends or the making of other distributions on, and upon the purchase, redemption or other acquisition by Lighting Science Group of, the common stock or shares of stock of any other class or any other series of this class;

(i) the conditions or restriction, if any, upon the creation of indebtedness of Lighting Science Group or upon the issue of any additional stock, including additional shares of such series or of any other series of this class or of any other class; and

(j) any other voting powers, designations, preferences, and relative, participating optional or other special rights, or qualifications, limitations or restrictions thereof, of the shares of such series.

The designations, voting powers, preferences and relative, participating, option or other special rights of each series of preferred stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding.

Dividends will accrue on the 6% convertible preferred stock from the closing date at an annual rate of 6%. Accrued dividends will be payable in cash quarterly. We will, however, have the right to pay dividends in shares of common stock; provided, however, that our right to pay dividends in shares of common stock on each dividend payment date is subject to the following conditions: (i) a registration statement covering the underlying common stock must be effective on such dividend payment date and available for use by the investors; and (ii) the number of shares issued will be based on a 15% discount to the daily volume weighted average price of the common stock for the 10 trading days immediately preceding (but not including) the applicable dividend payment date.

Shares of preferred stock will be entitled to voting rights on an “as if converted” basis.

Shares of preferred stock are convertible at the option of the holder at any time after the closing of the private placement and prior to redemption into shares of common stock, at an initial conversion price equal to $.80 per share of common stock. The initial conversion price is subject to full-ratchet anti-dilution adjustment in the event that the we issue, after May 12, 2005, common stock or common stock equivalents at a price per share less than the initial conversion price (other than (a) to a strategic investor in connection with a strategic commercial agreement or transaction as determined in good faith by the our board of directors, (b) pursuant to the acquisition of another corporation or entity by us by consolidation, merger, purchase of all or substantially all of the assets, or other reorganization, (c) pursuant to an authorized stock option plan, or (d) to an investor in connection with a joint venture arrangement where we are a participant (including, but not limited to, the joint venture arrangement with Giuliani Capital Advisors, LLC)), and to other normal and customary anti-dilution adjustments upon certain other events (including issuances at less than current market value).

Shares of the preferred stock will be entitled to a liquidation preference over other classes of our capital stock in an amount per share equal to the purchase price of the preferred stock. The liquidation right and preference will be applicable in the event of our liquidation, a merger of our company with or into another entity (i.e., the preferred shareholders will have a preference in the cash, securities or other consideration issued in such merger) or the sale by the us of all or substantially all of our business or operating assets.

We may force the conversion of any or all of the preferred stock at any time after the registration statement is effective and available for use by the Investors, if the closing price per share of the common stock exceeds 200% of the initial conversion price for any 20 out of 30 consecutive trading days; provided, however, that the average daily trading volume of the common stock must have exceeded 50,000 shares for the 20 consecutive trading days immediately preceding (but not including) the date that we first notify the Investors of the exercise of our option to force conversion.

Lighting Science Group must redeem all of the preferred stock outstanding on the fifth anniversary of the closing date at a redemption price, in cash, equal to the purchase price of the preferred stock, plus all accrued but unpaid dividends.

As mentioned above, our board of directors has the ability to issue “blank check” preferred stock in series, and shares of each series will have such rights, preferences, and privileges fixed by the Board of Directors in the resolutions authorizing the issuance of that particular series. The board of directors may issue any such series of blank check preferred stock without action by the holders of the common stock. Accordingly, the issuance of blank check preferred stock may adversely affect the rights of the holders of the common stock. In addition, the issuance of blank check preferred stock may be used as an ‘‘anti-takeover’’ device without further action on the part of the holders of the common stock. The issuance of preferred stock may also dilute the voting power of the holders of common stock, in that a series of preferred stock may be granted enhanced per share voting rights and the right to vote on certain matters separately as a class, and may render more difficult the removal of current management, even if such removal may be in the stockholders’ best interest. We have no current plans to issue any additional preferred stock.

As of January 31, 2006, Lighting Science Group has 10,298,733 warrants outstanding.

On February 10, 2005, Lighting Science Group agreed to issue The Equity Group two warrants to purchase an aggregate of $600,000 worth of shares of our common stock with each warrant having an exercise price based on the financing being contemplated by us at the time. Each warrant provides for the purchase of $300,000 worth of our common stock. One of the warrants became fully vested upon the signing of the contract. The other warrant will become exercisable upon the first anniversary date of the consulting contact unless terminated earlier. Based on the $0.80 initial conversion price of the 6% Convertible Preferred Stock issued by us in May 2005, the terms of each warrant was determined to be 375,000 common shares at a exercise price of $0.80 per share.

The warrant issued to Giuliani Capital Advisors, or GCA, is exercisable by GCA to purchase up to 1,650,000 shares of the Company’s common stock, subject to adjustment in certain circumstances as provided in the warrant. The warrant has a five-year term and GCA may exercise the warrant in whole or in part at any time during the five-year term. The exercise price for each share of common stock is $.60 per share or $990,000 if GCA were to exercise all 1,650,000 shares under the warrant.

As previously discussed, in 2005, certain individual members of our board of directors and members of senior management loaned Lighting Science Group an aggregate of $476,000 on a short-term basis pursuant to the terms of promissory notes from Lighting Science Group and in favor of each of the individual lenders. The board members and officers who loaned Lighting Science Group funds in this transaction are collectively referred to as the Lenders. The warrants issued to the Lenders for the purchase of 476,000 shares of our common stock are exercisable at $1.50 per share. Eight warrants for 30,000 shares of common stock and one warrant for 100,000 shares of common stock vested on the date of issuance, April 20, 2005. On April 29, 2005 and May 2, 2005, we issued warrants for 15,000 and 5,000 shares of common stock, respectively, to Mr. Lusk. On May 3, 2005, we issued a warrant for 100,000 shares of common stock to Mr. Snadon and on May 6, 2005, we issued a warrant for 16,000 shares to Mr. Harkleroad. All such warrants vested on the date of issuance. The warrants have anti-dilution and exercise price adjustment provisions for dividends and stock splits. Each warrant expires five years from the date of issuance.

In connection with the 6% Convertible Preferred Stock offering, Merriman Curhan Ford & Co. acted as placement agent for the transaction and MRM Capital LP served as a financial advisor to Lighting Science Group. Warrants to purchase a total of 639,844 shares of common stock at an exercise price of $1.50 per share were issued to Merriman and MRM in conjunction with this transaction. The warrants have anti-dilution and exercise price adjustment provisions for dividends and stock splits. Each warrant expires five years from the date of issuance.

Warrants Issued to 6% Convertible Preferred Stock Investors

In connection with the Securities Purchase Agreement under which we issued 2,260,966 shares of 6% convertible preferred stock, the purchasers also received warrants to purchase an additional 6,782,889 shares of common stock at an exercise price of $0.96 per share (subject to adjustment pursuant to anti-dilution provisions). Each warrant will represent the right to purchase one share of common stock. The initial exercise price of the warrants will be equal to 120% of the initial conversion price. The number of shares issuable upon exercise of the warrants and the exercise price per share will be subject to full-ratchet anti-dilution adjustment in the event that we issue, after May 12, 2005, common stock or common stock equivalents at a price per share less than the initial conversion price (other than (a) to a strategic investor in connection with a strategic commercial agreement or transaction as determined in good faith by the our board of directors, (b) pursuant to the acquisition of another corporation or entity by us by consolidation, merger, purchase of all or substantially all of the assets, or other reorganization, (c) pursuant to an authorized stock option plan, or (d) to an investor in connection with a joint venture arrangement where we are a participant (including, but not limited to, the joint venture arrangement with Giuliani Capital Advisors, LLC)), and to other normal and customary anti-dilution adjustments upon certain other events (including issuances at less than current market value).

We may force the exercise of any or all of the warrants at any time after a registration statement is effective and available for use by the investors in the preferred stock, if the closing price per share of the common stock exceeds 200% of the initial conversion price for any 20 out of 30 consecutive trading days; provided, however, that the average daily trading volume of our common stock must have exceeded 50,000 shares for the 20 consecutive trading days immediately preceding (but not including) the date that we first notify the investors of the exercise of our option to force exercise.

Each warrant will expire on the fifth anniversary of the closing date.

Effective September 1, 2005, we implemented the Lighting Science Group Corporation 2005 Equity Based Incentive Compensation Plan, or the 2005 Plan. Awards granted under the 2005 Plan may include incentive stock options, which are qualified under Section 422 of the Internal Revenue Code, or the Code, stock options other than incentive stock options, which are not qualified under Section 422 of the Code, stock appreciation rights, restricted stock, phantom stock, bonus stock and awards in lieu of obligations, dividend equivalents and other stock-based awards. Awards may be granted to employees, members of the Board of Directors, and consultants. The maximum number of shares reserved for the 2005 Plan is 5,000,000 shares. The 2005 Plan is administered by the Compensation Committee of the Board of Directors. Vesting periods and terms for awards are determined by the plan administrator. The exercise price of each stock option or stock appreciation right is equal to or greater than the market price of our common stock on the date of grant and no stock option or stock appreciation right granted shall have a term in excess of ten years.

As of January 31, 2006, Lighting Science Group has issued 730,000 Incentive Stock Options and 50,000 Non-Qualified Stock Options under the 2005 Plan. Such options have a term of four years and are vested one-third on the date of issuance and the subsequent two-thirds in equal parts on the first and second anniversaries thereof. Such options shall be exercisable only for cash, shall lapse if not exercised within four years following the date of issuance or, if earlier, within ninety days following the termination of employment or other affiliation with Lighting Science Group, shall be vested one-third on the date of issuance, and the subsequent two-thirds in equal parts on the first and second anniversaries thereof. The outstanding Incentive Stock Options were granted as follows:

Incentive Stock Options
Option Grant Date	# of Shares issued		Exercise Price
September 19, 2005	370,000	$	0.87
October 30, 2005	300,000	$	0.53
November 28, 2005	60,000	$	0.45
	730,000

 The date of issuance of the nonqualified stock options was September 19, 2005 and the exercise price per share of each option is $0.87, which was the closing price of the Lighting Science Group’s common stock on the date of issuance.

The transfer agent for the common stock is American Stock Transfer and Trust Company of Brooklyn, New York and its telephone number is (718) 921-8206.

PLAN OF DISTRIBUTION

We are registering the shares of common stock issuable upon conversion of the preferred stock (including common stock issuable upon exercise of the of the warrants) to permit the resale of these shares of common stock by the holders of the preferred stock, and warrants from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will, however, receive the proceeds from the exercise of the warrants issued to the selling stockholders if and when they are exercised. We will bear all fees and expenses incident to our obligation to register the shares of common stock. We will not be paying any underwriting discounts or commissions in this offering.

The selling stockholders may sell all or a portion of the shares of common stock beneficially owned by them and offered hereby from time to time directly or through one or more broker-dealers or agents. If the shares of common stock are sold through broker-dealers, the selling stockholders will be responsible for discounts or commissions relating to the sale of their securities. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be affected in transactions, which may involve crosses or block transactions, such as:

·   sales on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

·   sales in the over-the-counter market;

·   transactions otherwise than on these exchanges or systems or in the over-the-counter market;

·   the writing of options, whether such options are listed on an options exchange or otherwise;

·   ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

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

·   purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

·   an exchange distribution in accordance with the rules of the applicable exchange;

·   privately negotiated transactions;

·   short sales;

·   sales pursuant to Rule 144;

·   sales through broker-dealers who may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

·   a combination of any such methods of sale; and

·   any other method permitted pursuant to applicable law.

If the selling stockholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.

The selling stockholders may pledge or grant a security interest in some or all of the preferred stock, the warrants, or shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling stockholders and any broker-dealer participating in the distribution of the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act of 1933. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.

Under the securities laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement, of which this prospectus forms a part.

The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other person participating in this offering. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.

We will pay all expenses of the registration of the shares of our common stock pursuant to the registration rights agreement, estimated to be $210,558 in total, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws. However, the selling stockholders will pay all discounts and commissions, if any, relating to the sale of their securities. We have agreed to indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act of 1933, in accordance with the registration rights agreements, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related registration rights agreements or we may be entitled to contribution.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Section 145 of the Delaware General Corporation Law (the “DGCL”) generally provides that a corporation may indemnify directors, officers, employees or agents against liabilities they may incur in such capacities provided certain standards are met, including good faith and the reasonable belief that the particular action was in, or not opposed to, the best interests of the corporation.

Subsection (a) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that he is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful.

Subsection (b) of Section 145 empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted under standards similar to those set forth above, except that no indemnification may be made in respect of 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 Delaware Court of Chancery or the court in which such action or suit was brought shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.

Section 145 further provides that, among other things, to the extent that a director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in Subsections (a) and (b) of Section 145, or in the defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and that a corporation is empowered to purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify against such liability under Section 145.

Indemnification as described above shall be granted in a specific case only upon a determination that indemnification is proper under the circumstances using the applicable standard of conduct which is made by (a) a majority of directors who were not parties to such proceeding, (b) a committee of such directors designated by majority vote of such directors, (c) independent legal counsel in a written opinion if there are no such disinterested directors or if such disinterested directors so direct, or (d) the stockholders.

In accordance with Section 145 of the DGCL, Section 10 of Lighting Science Group’s Amended and Restated Certificate of Incorporation provides “To the fullest extent permitted by Section 145 of the General Corporation Law of the State of Delaware, as the same may be amended and supplemented, indemnify any and all persons whom it shall have the power to indemnify under said section from and against any and all of the expenses, liabilities or other matters referred to in or covered by said section, and the indemnification provided for herein shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any By-Law, agreement or vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.”

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or controlling persons of Lighting Science Group, pursuant to the foregoing provisions, or otherwise, Lighting Science Group 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.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Lighting Science Group Corporation

We have audited the accompanying consolidated balance sheet of Lighting Science Group Corporation and subsidiaries (a development stage company) (the company) as of December 31, 2005 and the related consolidated statements of operations, stockholders’ equity and cash flows for the years ended December 31, 2005 and 2004, and the period from September 26, 2003 (see Note 1) through December 31, 2005. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidences supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Lighting Science Group Corporation and subsidiaries as of December 31, 2005, and the consolidated results of their operations and cash flows for the periods indicated above, in conformity with United States generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 4 to the consolidated financial statements, the Company has experienced substantial net losses as well as negative cash flows from operations since September 26, 2003, that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 4. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

LIGHTING SCIENCE GROUP CORPORATION

AND SUBSIDIARIES

(A DEVELOPMENT STAGE COMPANY)

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Lighting Science Group Corporation (the “Company”) is a Delaware corporation organized in June 1988. The Company’s wholly owned subsidiaries during the periods were Americare Management, Inc. and LSGC LLC, a joint venture with Giuliani Capital Advisors LLC (Note 13). Americare Management, Inc. and LSGC LLC had no significant operations during the periods covered by these financial statements. All intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements.

As of December 31, 2005, the Company continues to operate as a development stage company, having not had appreciable revenue during 2005 or 2004. With its acquisition of certain intellectual property rights on June 1, 2004 (see Note 2), the Company entered the field of solid state lighting. Light emitting diode (“LED”) technology has been in use since 1962, but until recently was used only in small electronic devices. Manufacturers of LED’s have made substantial progress in the past few years, but the enabling technologies such as power conversion and thermal management have not kept pace. Consequently, the existing gap between the advancements in LED technology and their incorporation into general illumination systems has widened over the past five years.

Through the development of its Optimized Digital Lighting™ (“ODL™”) technology, the Company believes that it has begun to close the gap between the theoretical performance capability of today’s LED’s and the level of their performance in the current generation of general illumination products. The Company has developed several enabling technologies that form the basis of the intellectual property for which it has filed for patent protection.

The Company is currently designing several products for the consumer lighting market as well as commercial products for the streetlight and parking lot lighting sector. The Company has formed strategic alliances with a major parking facilities operator and a financial advisory services firm to target municipalities, public utility corporations, universities, large mall owners, parking lot owners, and other organizations as customers and partners for the Company’s products.

On or about August 20, 2002, the Company filed a voluntary petition seeking debtor-in-possession status for relief under Chapter 11 of the United States Bankruptcy Code. During the summer of 2003, the Company filed a Disclosure Statement and Plan of Reorganization (collectively, the “Plan”) that was confirmed by the U.S. Bankruptcy Court for the Northern District of Texas - Ft. Worth Division (the “Court”) on September 16, 2003 with an effective date of September 26, 2003. Under the terms of the Plan, the holder of the Series A Preferred Stock agreed to waive its rights, including its voting and conversion rights, and the creditors of the Company received an aggregate of approximately 51% of the common stock of the restructured entity in exchange for notes, accounts payable, and other forms of debt held at the time of the filing of the petition. This feature of the Plan - the exchange of debt for greater than 50% of the equity in the restructured entity - qualified the Company to utilize the reporting guidelines of the “Fresh Start” accounting rules contained in Statement of Position (“SOP”) 90-7 - Financial Reporting by Entities in Reorganization Under the Bankruptcy Code.

Reverse Stock Split

On August 20, 2004, the stockholders of the Company approved a proposal by management to undertake a reverse stock split of the shares of the Company’s common stock in the ratio of one share of new common stock for every 16 shares of old common stock. All per share amounts in the accompanying consolidated financial statements and in these notes to consolidated financial statements have been retroactively adjusted for the reverse split of the Company’s shares.

Summary of Significant Accounting Policies

Since the Chapter 11 bankruptcy filing, the Company has applied the provisions in SOP 90-7 which does not change the application of generally accepted accounting principles in the preparation of financial statements. However, it does require that the financial statements for periods including and subsequent to filing the Chapter 11 petition distinguish between transactions and events that are directly associated with the reorganization from the ongoing operations of the business.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates.

Cash and cash equivalents

All highly liquid investments with original maturities of three months or less at date of purchase are carried at cost, which approximates fair value, and are considered to be cash equivalents.

The Company maintains balances in cash accounts which could exceed federally insured limits of $100,000. The Company has not experienced any losses from maintaining balances in such cash accounts in excess of federally insured limits. Management believes that the Company does not have significant credit risk related to its cash accounts.

Inventories

Inventories, which consist of raw materials and components and lighting products designed by the Company and assembled by a third-party manufacturer, are stated at the lower of cost or market with cost being determined on a first-in, first-out basis. Deposits paid to contract manufacturers and raw material and components suppliers related to future purchases are also classified in inventory in the consolidated balance sheet.

Prepaid expenses and other current assets

Prepaid expenses and other current assets consist primarily of consulting fees paid to financial consulting firms and prepaid insurance policy premiums. Prepaid expenses are amortized over the period during which the service is provided or the length of the specific contract.

Property and equipment

Property and equipment are carried at depreciated cost. Depreciation is provided using the straight-line method over the estimated economic lives of the assets, which range from two to five years.

Depreciation expense was $73,233, $17,440 and $90,673 for the years ended December 31, 2005 and 2004 and cumulatively for the period beginning September 26, 2003 and ending December 31, 2005, respectively.

Other assets

Other assets consist of acquisition-related intangible assets and an intangible asset arising upon the Company’s emergence from bankruptcy.

Acquisition-related intangible assets

The acquisition of the stock of Lighting Science, Inc. on June 1, 2004 necessitated an allocation of the purchase price among the assets of the acquired company. An independent valuation firm was engaged by the Company to perform this allocation. At the date of acquisition, Lighting Science, Inc. owned no tangible assets. As a result, the net purchase price of $2,231,097 was allocated to current assets, three classes of intangible assets, and liabilities as follows: Cash - $10,000; Intellectual Property - $1,204,000; Proprietary Rights Agreement - $1,063,000; Goodwill - $154,097, and Notes Payable - $200,000. The acquisition of Lighting Science, Inc. is described in greater detail in Note 2.

Intellectual property, which includes, but is not limited to, provisional patents, copyrights, intellectual assets and proprietary know-how, was recorded effective June 1, 2004 as a part of the allocation of the purchase price of Lighting Science, Inc. The intellectual property is being amortized over twenty years beginning June 1, 2004.

Amortization expense related to intellectual property was $60,200, $35,117 and $95,317 for the years ended December 31, 2005 and 2004 and cumulatively for the period beginning September 26, 2003 and ending December 31, 2005, respectively.

The proprietary rights agreement between the Company and Fredric Maxik (the Company’s chief technology officer and the developer of the technology acquired by the Company), ensures that all intellectual property created and/or developed by Maxik during his employment and for some period thereafter shall be assigned to the Company as well as precluding Maxik from competing with or providing services for entities in competition with the Company or that have technology similar to the Company for a period of time following his employment termination with the Company. This Agreement was recorded effective June 1, 2004, as part of the purchase price of Lighting Science, Inc. This asset is being amortized over three years, which is the period covered by the agreement.

Amortization expense related to the proprietary rights agreement was $354,333, $206,694 and $561,027 for the years ended December 31, 2005 and 2004 and cumulatively for the period beginning September 26, 2003 and ending December 31, 2005.

Reorganization Value

As a result of the terms of the Plan, $2,793,224 is reflected as reorganization value in excess of amounts allocable to identifiable assets on the consolidated balance sheet. The circumstances giving rise to this presentation were created by a provision in the Plan that preserved the secured claim of Match, Inc. (see Note 9). Match, Inc. (“Match”), an entity controlled by Ronald E. Lusk, the Company’s chairman, agreed to the reaffirmation of its debt. As a result of this reaffirmation, which is part of the confirmation of the Plan, an offsetting entry to the reorganization value was recorded. In accordance with the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 142 - Goodwill and Other Intangible Assets, the reorganization value is treated the same as goodwill and is not amortized.

Impairment

The Company evaluates the carrying value of its long-lived assets and identifiable intangibles when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The review includes an assessment of industry factors, contract retentions, cash flow projections and other factors the Company believes are relevant.

Based upon its internal review as of September 30, 2005, the Company has determined that no impairment to the Company’s intangible assets has occurred since the date of the previous evaluation.

Financial Instruments

The Company has issued certain preferred stock and warrants, the terms of which qualify these financial instruments under SFAS 133 - Accounting for Derivative Instruments and Hedging Activities, as derivatives. Such derivatives have not been designated as hedging instruments. Accordingly, all derivatives are recorded at fair value on the consolidated balance sheet and changes in the fair value of such derivatives are recorded in operations each period and are reported in Other Income (Expense).

Revenue

Product sales are recorded when the products are shipped and title passes to customers. Where sales of product are subject to certain customer acceptance terms, revenue from the sale is recognized once these terms have been met. Sales to date have not been significant.

As of the date of this report, the Company has no reason to believe that an allowance for material product returns is necessary.

Stock Based Compensation

On July 6, 2005, the Board of Directors of the Company adopted the Lighting Science Group Corporation 2005 Equity Based Incentive Compensation Plan (the "2005 Plan") and a proposal to implement this plan was approved at the annual shareholders’ meeting in August 2005. Effective with adoption of the plan, the Company adopted the fair value method of accounting for employee stock compensation cost pursuant to SFAS No. 123 (R) - Share-Based Payment. Accordingly, compensation cost is based on the fair value of options or other equity instruments measured at the date of grant and compensation cost is charged to operations over the expected service period.

Income taxes

The Company employs the asset and liability method in accounting for income taxes pursuant to SFAS No. 109 - Accounting for Income Taxes. Under this method, deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities and net operating loss carryforwards, and are measured using enacted tax rates and laws that are expected to be in effect when the differences are reversed.

Earnings per share

Basic earnings per share are computed based upon the weighted average number of common shares outstanding during the periods. Diluted earnings per share are based upon the weighted average number of common shares outstanding during the periods plus the number of incremental shares of common stock contingently issuable upon the conversion of the preferred stock and the exercise of warrants and stock options. No effect has been given to the assumed conversion of the preferred stock or the exercise of warrants or stock options because the effect would be anti-dilutive. See Notes 10 through 13.

Comparative Consolidated Financial Statements

Certain amounts in the comparative consolidated financial statements have been reclassified from financial statements previously presented to conform to the presentation of the 2005 consolidated financial statements.

NOTE 2: ACQUISITION OF LIGHTING SCIENCE, INC.

On June 1, 2004, the Company acquired 100% of the outstanding common stock of Lighting Science, Inc., a Delaware corporation based in Las Vegas, Nevada, which owned certain intellectual property related to the design and development of an ODL light bulb. The Company acquired all of the issued and outstanding capital stock of Lighting Science, Inc. from Phibian S Trust, Edward I. Lanier, and John Collingwood in exchange for 4,796,276 shares of the Company’s common stock and the Company’s obligation to issue up to an additional 4,499,965 shares of the Company’s common stock upon the satisfaction of certain conditions under the stock purchase agreement. Those conditions were satisfied during the third quarter of 2004, and the additional shares of common stock were issued on or about September 3, 2004.

The Company accounted for the acquisition as a purchase using the accounting standards established SFAS No. 141 - Business Combinations, and No. 142 - Goodwill and Other Intangible Assets.

The estimated fair values, as determined by an independent valuation firm, of assets acquired and liabilities assumed at June 1, 2004 are set out in the schedule below:

Cash	$	10,000
Intellectual property		1,204,000
Proprietary rights agreement		1,063,000
Goodwill		154,097
Total assets acquired			$	2,431,097
Note payable assumed				(200,000	)
Net assets acquired			$	2,231,097

Lighting Science, Inc. was formed on or about May 31, 2004 for the purpose of acquiring intellectual property from Phibian S Trust. There were no predecessor operations with respect to this entity, therefore, no pro forma results of operations are presented.

Intellectual Property

As of the date of acquisition, four provisional patents on the ODL technology had been submitted to the United States Patent and Trademark Office and were acquired by Lighting Science, Inc. Provisional patents are equivalent to a filing date placeholder in the United States Patent Office (“USPTO”). They provide a one-year period following submittal in which to finalize the utility patent application with respect to the particular idea, process, concept or method contained in a provisional patent.

Subsequent to the acquisition of Lighting Science, Inc., the Company filed four utility patent applications (thereby complying with the one-year time period mentioned above) based on the initial four provisional patents. Eleven additional patent applications have also been filed to provide further protection to the ODL technology. Two of such fifteen patent applications have been granted. Accordingly, there are currently thirteen utility patents pending with respect to the ODL technology before the USPTO. It is anticipated that it will be about 18 months to two years from the date of filing of the utility applications before the USPTO will issue a response to the filing. Additionally, with respect to proprietary branding of its products and services, the Company has filed for federal trademark/service registrations on certain marks and anticipates filing additional registrations on other marks and logos, and, as appropriate, the Company has also established common law trademark protection on several marks and logos. Further, other appropriate intellectual property protection, such as copyright and trade secret, is being applied to the ODL technology and the lighting products which embody it. It is also the policy of the Company to develop an intellectual property portfolio that protects and enhances the ODL technology ideas, concepts, methods and processes. The Company has also adopted intellectual property policies, procedures and practices into its business operations to facilitate its proprietary positioning with respect to its product development and commercialization.

NOTE 3: FRESH-START ACCOUNTING

The Court confirmed the Company’s Plan (Note 1) on September 16, 2003, and the Plan became effective as of September 26, 2003. It was determined that the Company’s reorganization value, computed immediately before the effective date, was $2,793,502, which consisted of the following:

Cash	$	278
Reorganized value in excess of amounts allocable to identifiable assets		2,793,224
Deferred tax assets comprised of $57,000,000 of net operating loss carry-forwards		19,400,000
Valuation allowance against above deferred tax assets		(19,400,000	)
Reorganization value	$	2,793,502

The Company adopted fresh-start reporting because holders of existing voting shares immediately before filing and confirmation of the Plan retained less than 50% of the voting shares of the emerging entity, and its reorganization value was less than its post-petition liabilities and allowed claims.

NOTE 4: GOING CONCERN

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As shown in the consolidated financial statements, the Company has experienced substantial net losses as well as negative cash flows from operations since September 26, 2003.

The Company has embarked upon an aggressive design and development program to bring product to market during the current year. To provide the Company with adequate working capital for the design and the initial manufacture of these products, the Company completed a transaction with a group of institutional and accredited investors in May 2005 whereby the Company issued 2,260,966 shares of the Company’s 6% Convertible Preferred Stock for proceeds totaling $7,235,086 in a private placement transaction (Note 10).

Based upon the receipt of proceeds from the private placement of the Company’s 6% Convertible Preferred Stock and revenue from anticipated product releases, management believes that the Company will have sufficient capital necessary to enable it to deliver finished products to market during 2006. Despite these activities, there can be no assurance that management’s efforts to sufficiently capitalize the Company beyond the initial rollout of the Company’s product line will be successful.

NOTE 5: FAIR VALUE OF FINANCIAL INSTRUMENTS

SFAS No. 107 - Disclosures About Fair Value of Financial Instruments, requires that the Company disclose estimated fair values of financial instruments.

Cash and cash equivalents, accounts receivable, notes and accounts payable, accrued expenses and other current liabilities are carried at book value amounts which approximate fair value due to the short-term maturity of these instruments. As discussed in Note 10, the embedded conversion feature associated with the 6% Convertible Preferred Stock and the warrants issued to the 6% Convertible Preferred Stock purchasers have been determined to be derivative instruments and are recorded at market.

NOTE 6: INVENTORY

At December 31, 2005, inventory is comprised of the following:

		December 31, 2005
Deposits paid to contract manufacturers	$	156,140
Raw materials and components		213,057
Finished goods		248,321
	$	617,518

At December 31, 2005 the Company provided an allowance for the decline in market value of certain raw materials and components of approximately $87,000, which is netted against the balance of raw materials and components in the table above.

NOTE 7: PROPERTY, EQUIPMENT AND OTHER ASSETS

Property and equipment consists of the following:

		December 31, 2005
Leasehold Improvements	$	5,526
Office furniture, fixtures and telephone equipment		97,152
Computer equipment		103,008
Test Equipment		94,988
Tooling and molds		52,609
Total property and equipment		353,283
Accumulated depreciation		(57,947	)
	$	295,336

During 2005, the Company incurred a loss on the disposal of property and equipment of $97,155. Of this amount, $77,304 related to the write-off of prototype tools and molds that were no longer being used by the Company for the manufacture of parts due to the development of production tooling and more advanced prototypes. The Company does not use these prototype tools and molds for any other purpose.

Intellectual property consists of the following:

		December 31, 2005
Intellectual property	$	1,204,000
Accumulated amortization		(95,317	)
	$	1,108,683

Proprietary rights agreement consists of the following:

		December 31, 2005
Property rights agreement	$	1,063,000
Accumulated amortization		(561,028	)
	$	501,972

The estimated amortization expense for the next five years for the intangible assets listed above is as follows:

	Amortization Expense
Year ended		Intellectual Property		Proprietary Rights Agreement
2006	$	60,200	$	354,333
2007	$	60,200	$	147,639
2008	$	60,200		-
2009	$	60,200		-
2010	$	60,200		-

NOTE 8: INCOME TAXES

The Company accounts for corporate income taxes in accordance with SFAS No. 109 - Accounting for Income Taxes. Under SFAS No. 109, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. In addition, future tax benefits, such as those from net operating loss carry forwards, are recognized to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as set forth below in the period that includes the enactment date.

Other than the deferred tax asset relating to the Company’s net operating losses, which totaled approximately $23,200,000 at December 31, 2005, and which has been fully offset by a valuation reserve, the Company does not have any other significant deferred tax assets or liabilities. The Company has recorded a change in the valuation allowance of $2,300,000, $1,500,000 and $3,800,000 for the years ended December, 31, 2005 and 2004 and cumulatively for the period beginning September 26, 2003 and ending December 31, 2005, respectively. The net operating loss carryforwards are available to offset future taxable income of the Company. These net operating losses expire from 2008 through 2020. The change in the fair value under derivative contracts of $3,907,649 (Note 10) has been treated as a permanent difference to calculate the total net operating losses available for carryforward to offset future periods’ taxable income.

Benefits realized in future periods from the application of net operating losses incurred prior to September 26, 2003 of $19,400,000 will first reduce reorganization value in excess of amounts allocable to identifiable assets until exhausted and, thereafter, will be credited to additional paid in capital. Any benefits realized in future periods from net operating loss carryforwards generated after September 26, 2003 ($3,800,000 at December 31, 2005) will be recorded as a tax benefit in the statement of operations.

NOTE 9: NOTES PAYABLE - RELATED PARTIES

Match Loan

We were obligated under the terms of a line of credit agreement to Match outstanding in the amount of $1,851,299 in principal and $341,226 in accrued interest at March 31, 2005. The line of credit agreement with Match, Inc. was available up to a limit of $2 million; bearing interest at prime plus 1% on the note balance and prime plus 2% on any unpaid interest amounts; was due on demand and was unsecured.

We entered into an agreement with Match on April 12, 2005, under which Match agreed to reduce the accrued interest by $250,000 and exchange the debt for common stock at the exchange ratio of $1.725 per share. On May 5, 2005, the debt to Match of $1,851,299 plus $91,226 of accrued interest was exchanged for common stock. The reduction in accrued interest was recorded in Other income/(expense) during the year ended December 31, 2005. As a result of these transactions, the total of $1,942,525 due on the line of credit was exchanged for 1,126,101 shares of common stock of the Company on May 5, 2005.

Note to Phibian S Trust

Upon the acquisition of Lighting Science, Inc. we owed a balance of $200,000 to Phibian S Trust of which the remaining balance of $150,000 and is recorded as follows:

		December 31, 2005
Notes payable - related party - current portion	$	38,889
Notes payable - related party - long-term portion		111,111
	$	150,000

The Phibian S Trust is a trust for the benefit of the children of Fredric Maxik, the chief technology officer of the Company. At the time of the acquisition, the trust was controlled by Mr. Maxik who was co-trustee of the trust. On July 2, 2004, Maxik resigned his position as co-trustee. Currently, Maxik exercises no control over the trust, and has informed us that he disclaims all beneficial ownership in the trust. The note was issued by Lighting Science, Inc. to the trust in exchange for the assignment of certain provisional patents and intellectual property that formed the basis for the acquisition of Lighting Science, Inc. by the Company. The Company is obligated to pay the principal by making 36 equal monthly installments beginning on the fifteenth day of the month following the first full month that the Company begins generating revenue in the amount of $10,000 or more, as determined in accordance with generally accepted accounting principles. The Company will begin paying regular monthly installments on the note beginning in June 2006, after giving effect to the $50,000 in prepayments noted above. Accordingly, payments relating to the period from June 2006 through December 2006 have been classified as current liabilities.

As an accommodation to the trust and in anticipation of near-term sales in excess of $10,000 per month, the Company made advance payments to the trust on this note in the amount of $25,000 in October 2004 and $25,000 in May 2005. This note provides for no interest. However, under generally accepted accounting principles, an amount of interest should have been imputed. Such amount was not material.

Loans from Directors and Officers

During the first and second quarters of 2005, members of the board of directors and certain officers of the Company (the “Lender” or “Lenders”) agreed to loan the Company an aggregate of $476,000 on a short-term basis, of which $220,000 was received as of March 31, 2005 and the remaining $256,000 was received in the quarter ended June 30, 2005. Proceeds from the loans funded the Company’s continuing operating expenses, ongoing expenses for salaries, legal and accounting fees, as well as for working capital and other contingencies. Under the terms of the notes issued by the Company to each Lender, the Company: (i) paid interest to each Lender at a rate of 9.50% per annum; (ii) paid a 10% commitment fee to each Lender and (iii) issued warrants to the Lenders for a total of 476,000 shares of common stock to be purchased at an exercise price of $1.50 per share. The principal and interest on the notes were due on May 30, 2005. A total of $300,086 of such loans, including accrued interest and commitment fees of $24,086, were converted to Preferred Stock in the private placement of preferred stock (Note 10) and the remaining $200,000 of such loans and accrued interest and commitment fees thereon were repaid from proceeds of the private placement.

NOTE 10: PREFERRED STOCK

At the date of acquisition of Lighting Science, Inc. by the Company (June 1, 2004), Lighting Science, Inc. had 100,000 shares of preferred stock authorized with no shares issued or outstanding. As of December 31, 2004, this issue of preferred stock was still authorized, however no shares had been issued. Effective January 1, 2005, this stock was cancelled under the merger agreement between Lighting Science, Inc. and its parent company, Lighting Science Group Corporation.

Exchange of Series A Preferred Stock held by Match for Common Stock

On July 25, 1994, Lighting Science Group sold, for proceeds of $2 million, 533,333 shares of Series A Preferred Stock with cumulative dividends of $0.30 per annum per share and conversion rights to common stock at a price of $3.75 per share. Under the terms of the Plan under which the Company emerged from bankruptcy, such rights were waived, including voting and conversion rights.

On April 12, 2005 the Company announced that the Company and Match had negotiated the exchange of the 533,333 shares of Series A Preferred Stock held by Match and the Match debt (See Note 9) into common stock of the Company at a exchange ratio of $1.725 per share that was approximately 15% in excess of the market price of the stock at the date the exchange was proposed, resulting in fewer shares being issued to Match than would have been issued had the then current market price of the stock been used.

The Series A Preferred Stock, owned by Match at the date of the exchange, carried cumulative dividends of $0.30 per annum per share. The cumulative unpaid dividend with respect to the Series A Preferred Stock was $1,680,000 as of March 31, 2005, resulting in a total liquidation preference of $3,680,000 as of that date. However, for purposes of the exchange calculation, the amount of $1,670,685 was used to reflect the unpaid dividend on the date the exchange ratio of $1.725 per share was determined. This adjustment produced the slightly smaller liquidation value of $3,670,685 and this amount was used to record the dividend as a charge to Deficit accumulated during the development stage on the balance sheet. Thus, the Series A Preferred Stock owned by Match and the accumulated dividend thereon was exchanged for 2,127,933 shares of common stock on May 5, 2005. The accumulated dividend was recorded as a reduction of retained earnings.

Private Placement with Institutional and Accredited Investors

On May 12, 2005, the Company closed on a private placement with a group of institutional and accredited investors, including certain officers and directors of the Company, for the sale of 2,260,966 shares of the Company’s 6% Convertible Preferred Stock (the “6% Convertible Preferred Stock”) along with warrants to purchase additional shares of the Company’s common stock. The 6% Convertible Preferred Stock was priced at $3.20 per share, and the Company received proceeds of $7,235,086 of which $276,000 represented conversion of officer and board member loans and $24,086 represented accrued interest and commitment fees thereon. Each share of 6% Convertible Preferred Stock is convertible at any time at the election of the holder at $0.80 per share into four shares of common stock, subject to full ratchet anti-dilution adjustments. Thus, if all of the shares of the 6% Convertible Preferred Stock were converted to common stock, an additional 9,043,864 shares of common stock would be issued.

The 6% Convertible Preferred Stock ranks ahead of the common stock of the Company upon liquidation of the Company. The 6% Convertible Preferred Stock also ranks ahead of the common stock with respect to the payment of dividends. The dividend rate on the 6% Convertible Preferred Stock is $0.192 per share per annum (6% effective yield) and such dividends are fully cumulative, accruing, without interest, from the date of original issuance of the 6% Convertible Preferred Stock through the date of redemption or conversion thereof. The Corporation must redeem any outstanding 6% Convertible Preferred Stock on May 10, 2010. In connection with the transaction, the Company filed a certificate of designation for the 6% Convertible Preferred Stock with the Delaware Secretary of State on May 10, 2005. This filing constituted an amendment to the Company's certificate of incorporation, designating the terms, rights and preferences of a new series of preferred stock of the Company.

The warrants are exercisable at the election of the holder into a total of 6,782,889 shares of common stock at an initial exercise price of $0.96 per share (also subject to adjustment pursuant to anti-dilution provisions) on either a cash or cashless exercise basis. The warrants expire five years from the date of issuance.

Pursuant to SFAS 133 and EITF Abstract No. 00-19, the embedded conversion feature associated with the 6% Convertible Preferred Stock and the warrants issued to the 6% Convertible Preferred Stock purchasers have been determined to be derivative instruments. Accordingly, the fair value of these derivative instruments has been recorded as a liability on the consolidated balance sheet with the corresponding amount recorded as a discount to the 6% Convertible Preferred Stock. Such discount is being accreted from the date of issuance to the redemption date of the 6% Convertible Preferred Stock and totaled $927,677 for the period from the date of issuance (May 12, 2005) to December 31, 2005. The change in the fair value of the liability for derivative contracts totaled $(3,907,649) in 2005 and has been credited to Other income/(expense) in the consolidated statements of operations.

The Company computes fair value of these derivatives using the Black-Scholes valuation model. The Black-Scholes model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. The Company’s derivative instruments have characteristics significantly different from traded options, and the input assumptions used in the model can materially affect the fair value estimate. The assumptions used in this model to estimate fair value of each derivative instrument and the resulting value of the derivative liability as of December 31, 2005 are as follows:

		Warrants			Embedded conversion feature associated with the 6% Convertible Preferred Stock
Exercise/Conversion Price	$	0.96		$	0.80
Fair Value of the Company’s Common Stock	$	0.58		$	0.58
Expected life in years		4.4			4.4
Expected volatility		75	%		75	%
Expected dividend yield		0.0	%		0.0	%
Risk free rate		4.09	%		4.09	%
Calculated fair value per share	$	0.29		$	0.31

The 6% Convertible Preferred Stock is Mandatorily Redeemable Preferred Stock as defined by SFAS 150 - Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, and would also qualify as “Preferred Stocks Subject to Mandatory Redemption Requirements or Whose Redemption is Outside the Control of the Issuer” as defined by Accounting Series Release (“ASR”) No. 268 - Redeemable Preferred Stocks. The conversion feature associated with the 6% Convertible Preferred Stock is not a nonsubstantive or minimal feature and therefore the provisions of ASR No. 268 have been applied in classifying the 6% Convertible Preferred Stock separate from Stockholders’ Equity (Deficit).

The Company incurred cash expenses totaling $700,859 related to this transaction which have been charged to Other income/(expense) in the statements of operations during the three months ended June 30, 2005. Additionally, the Company issued warrants to purchase a total of 639,844 shares of the Company’s common stock at an initial exercise price of $1.50 per share (also subject to adjustment pursuant to anti-dilution provisions) to the firms which acted as the placement agent and as financial advisor for this transaction. The warrants expire five years from the date of issuance. The fair value of these warrants totaled $290,000 and such amount was charged to Other income/(expense) and credited to Additional Paid-In Capital during the three months ended June 30, 2005.

NOTE 11: STOCKHOLDERS’ EQUITY

Lighting Science Private Placement

In connection with the acquisition of Lighting Science, Inc., the Company undertook a private placement (“Lighting Science Private Placement”) of the Company’s common stock under the exemption of Section 505 of Regulation D of the Securities Act of 1933. On March 4, 2005 the Company amended its filing of Form D (Notice of Sale of Securities Pursuant to Regulation D, Section 4(6), and/or Uniform Limited Offering Exemption) to elect the exemption under Rule 506 rather than Rule 505 for the sale of the Company’s common stock. Under Rule 506, the Company can raise an unlimited amount of money from any number of “accredited” investors and up to 35 “non-accredited” investors. A total of $3,874,890 had been raised through the sale of 18,383,573 shares of the Company’s common stock. There have been no such sales of the Company’s stock subsequent to that date. The total of $3,874,890 includes $500,000 of accrued but unpaid interest on a note payable to Match. In lieu of disbursing cash in payment of the interest expense, the Company issued stock to the Ronald E. Lusk Revocable Trust (the “Trust”) the owner of Match. The Trust had contemporaneously subscribed to purchase $500,000 of stock under the terms of the Lighting Science Private Placement.

NOTE 12: EQUITY BASED COMPENSATION PLAN

Effective September 1, 2005, the Company implemented the Lighting Science Group Corporation 2005 Equity Based Incentive Compensation Plan. Awards granted under the 2005 Plan may include incentive stock options, which are qualified under Section 422 of the Internal Revenue Code (the "Code"), stock options other than incentive stock options, which are not qualified under Section 422 of the Code, stock appreciation rights, restricted stock, phantom stock, bonus stock and awards in lieu of obligations, dividend equivalents and other stock-based awards. Awards may be granted to employees, members of the Board of Directors, and consultants. The maximum number of shares reserved for the 2005 Plan is 5,000,000 shares. The 2005 Plan is administered by the Compensation Committee of the Board of Directors. Vesting periods and terms for awards are determined by the plan administrator. The exercise price of each stock option or stock appreciation right is equal to or greater than the market price of the Company's stock on the date of grant and no stock option or stock appreciation right granted shall have a term in excess of ten years.

During 2005, the Company issued 730,000 Incentive Stock Options to employees and directors and 50,000 Non-Qualified Stock Options to a consultant under the 2005 Plan. Such options have a term of four years and are vested one-third on the date of issuance and the subsequent two-thirds in equal parts on the first and second anniversaries thereof.

The fair value of the options is determined by using a Black-Scholes pricing model that includes the following variables: 1) exercise price of the instrument, 2) fair market value of the underlying stock on date of grant, 3) expected life, 4) estimated volatility, 5) expected dividend yield and 6) the risk-free interest rate. The Company utilized the following assumptions in estimating the fair value of the options granted during 2005:

Exercise price	$0.87 - $0.45
Fair market value of the underlying stock on date of grant	$0.87 - $0.45
Expected life in years	2.5
Estimated volatility	75	%
Expected dividend yield	0.0	%
Risk free rate	4.09% - 3.75	%
Calculated fair value per share	$0.41 - $0.21

As noted previously, the Black-Scholes model was not developed for use in valuing employee stock options, but was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Because changes in the subjective assumptions can materially affect the fair value estimate, and because employee stock options have characteristics significantly different from those of traded options, the use of the Black-Scholes option pricing model may not provide a reliable estimate of the fair value of employee stock options. For purposes of this calculation, the Company has utilized the simplified method specified in Staff Accounting Bulletin No. 107 for estimating the expected life in years of the options. Under this approach, the expected term is presumed to be the mid-point between the vesting date and the end of the contractual term. The Company has estimated volatility of its stock based on the historical volatility of the Company’s common stock. The Company has estimated the future volatility of its common stock based on the actual volatility of its common stock over the past year.

The fair value of the options issued 2005 totaled $266,700 of which $111,109 was recorded in operating expense in the consolidated statements of operations based on service conditions and vesting.

A summary of the option awards under the Company’s 2005 Plan as of December 31, 2005 and changes during the year then ended is presented below:

Stock Options		Shares			Weighted Average Exercise Price
Outstanding and exercisable, beginning of period		-			-
Granted		780,000		$	0.71
Exercised		-			-

NOTE 13: COMMITMENTS AND CONTINGENCIES

Leased office space

The Company occupies office space that is leased by an institutional shareholder of the Company who also provided financial advisory services to the company during 2005. Effective with the termination of the financial advisory agreement as of September 30, 2005, the Company pays the shareholder $10,000 per month under a month to month agreement. Prior to that time, the Company was using the office space rent free. Such rent was not material. The Company has leased space in Sunrise, Florida for its research and development activities for a period of fifteen months commencing November 1, 2005. The space is being leased from a company that is also a contract manufacturer for the Company. For the period from November 1, 2005 through January 31, 2005 the company will pay rent of approximately $2,300 per month and for the period from February 1, 2005 through the end of the lease term, it will pay approximately $2,500 per month. The Company also leases space in Hong Kong and storage space in Dallas, TX on a month-to-month basis at a total rate of approximately $650 per month.

From time to time, the Company may become involved in lawsuits or other legal proceedings through the ordinary course of operating its business. The Company does not believe these actions will have a material effect on its consolidated financial statements.

Financial advisory services

In 2004, the Company entered into an agreement with a financial consulting firm located in Dallas, Texas to provide financial advisory services in connection with the Company’s capital structure. Under the terms of the agreement, the Company paid the advisor a retainer of $150,000 during the fourth quarter of 2004 for services anticipated to be rendered during calendar year 2005, which was recorded in prepaid expenses. The agreement also provided for monthly payments of $10,000 during the one-year term of the agreement. This financial advisory agreement was terminated as of September 30, 2005.

Agreement with Giuliani Capital Advisors

On February 15, 2005, the Company entered into a letter agreement with Giuliani Capital Advisors LLC (“GCA”) to engage GCA to provide financial advisory services to the Company and a to-be-formed entity (the “Joint Venture”). The joint venture agreement was subsequently executed on May 4, 2005.

As consideration for the services to be provided by GCA, the Company agreed to pay GCA the following:

·   A non-refundable deposit of $150,000 (paid on March 31, 2005 and recorded in prepaid expenses);

·   A market rate fee for all debt and/or equity capital raised for the Joint Venture; and

·   Reasonable expenses of GCA incurred in performing its services.

In addition, GCA will receive the following:

·   A financial advisory role in the Joint Venture on capital raising transactions on a case by case basis; and

·   A 20% ownership interest in the Joint Venture.

The Company also issued a warrant to GCA that is exercisable by GCA to purchase up to 1,650,000 shares of the Company’s common stock, subject to adjustment in certain circumstances as provided in the warrant. The 1,650,000 shares represented 3.2% of outstanding shares of common stock at February 15, 2005. The warrant has a five-year term and GCA may exercise the warrant in whole or in part at any time during the five-year term. The exercise price for each share of common stock is $.60 per share or $990,000 if GCA were to exercise all 1,650,000 shares under the warrant.

Consulting Contract with Equity Group, Inc.

On February 10, 2005, the Company entered into a consulting contract with Equity Group, Inc. (“Equity”) to provide financial public relations and investor relations on behalf of the Company. In connection therewith, the Company agreed to issue Equity two warrants to purchase an aggregate of $600,000 worth of shares of the Company’s common stock with each warrant having an exercise price of $0.80 per share. Each warrant will provide for the purchase of $300,000 worth of common stock of the Company. One of the warrants became fully vested upon the signing of the contract. The other warrant will become exercisable upon the first anniversary date of the consulting contact unless terminated earlier. Equity will receive $5,000 per month during the term of the contract.

Executive Compensation

As of December 31, 2005, the Company was obligated under the terms of employment contracts for five of its executives. The terms of the contracts generally range between one and three years, and provide for annual salaries ranging between $90,000 and $250,000 per year. The annual compensation for the Company’s executives under these agreements is expected to be approximately $910,000 for 2006.

Commission Agreements with Directors

Pursuant to a resolution passed by the Board of Directors on February 7, 2005, the Company is obligated to pay outside directors a commission of 3% of the proceeds for any Shared Savings Program contracts which a director is responsible for closing. During the second quarter or 2005, the Company entered into a sales commission agreement with J. Michael Poss, the chief financial officer of the Company at the time and a member of the board of directors, to pay Mr. Poss a commission of 6% of the contract proceeds for any Shared Savings Program and 3% of revenue for other product sales which he is responsible for closing.

Registration Rights Agreement

In connection with the issuance of 6% Convertible Preferred Stock (Note 10), the Company executed a Registration Rights Agreement with the purchasers thereof under which the Company agreed to register the common shares underlying the 6% Convertible Preferred Stock and related warrants. The Registration Rights Agreement provides for liquidated damages in the event a registration statement is not declared effective by the SEC within 150 days of the May 12, 2005 closing date or if the registration statement is not maintained effective for a period of two years following the closing date. The liquidated damages total an amount equal to two percent of the purchase price of the 6% Convertible Preferred Stock for each thirty (30) day period effectiveness of a registration statement is not maintained.

In connection therewith, on July 12, 2005, the Company filed on Form SB-2, a Registration Statement under the Securities Act of 1933, related to the sale of up to 30,727,420 shares of Lighting Science Group Corporation common stock, par value $.001 by the selling stockholders named therein. Of the common stock offered thereby, (i) 9,043,864 shares of the common stock are issuable upon conversion of $7,235,086 aggregate principal amount of our 6% Convertible Preferred Stock, (ii) 7,422,733 shares of common stock are issuable upon exercise of warrants issued in connection with the sale of the 6% Convertible Preferred Stock, and (iii) 14,260,823 shares of common stock were acquired prior to May 12, 2005 by certain selling stockholders who agreed to the terms of a lock-up agreement dated as of May 12, 2005 and which may not be sold by the selling stockholders except pursuant to the lock-up agreement. The Company will not receive any proceeds from any sales made by the selling stockholders but will pay the expenses of the offering. We will, however, receive the proceeds from the exercise of the warrants issued to the selling stockholders if and when they are exercised. This registration was declared effective by the SEC on August 23, 2005, and remains effective as of the date of this filing.

NOTE 14: SUBSEQUENT EVENT

In January 2006, a former executive of the Company returned to the Company 100,000 shares of its common stock. The stock was returned to the Company pursuant to the termination of the former executive’s employment agreement with the Company. The shares were returned to the Company in return for the Company agreeing to waive certain obligations of the former executive under the terminated employment agreement. The returned shares will be cancelled.

PART II. INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law (the “DGCL”) generally provides that a corporation may indemnify directors, officers, employees or agents against liabilities they may incur in such capacities provided certain standards are met, including good faith and the reasonable belief that the particular action was in, or not opposed to, the best interests of the corporation.

Subsection (a) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that he is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful.

Subsection (b) of Section 145 empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted under standards similar to those set forth above, except that no indemnification may be made in respect of 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 Delaware Court of Chancery or the court in which such action or suit was brought shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.

Section 145 further provides that, among other things, to the extent that a director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in Subsections (a) and (b) of Section 145, or in the defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and that a corporation is empowered to purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify against such liability under Section 145.

Indemnification as described above shall be granted in a specific case only upon a determination that indemnification is proper under the circumstances using the applicable standard of conduct which is made by (a) a majority of directors who were not parties to such proceeding, (b) a committee of such directors designated by majority vote of such directors, (c) independent legal counsel in a written opinion if there are no such disinterested directors or if such disinterested directors so direct, or (d) the stockholders.

In accordance with Section 145 of the DGCL, Section 10 of Lighting Science Group’s Amended and Restated Certificate of Incorporation provides “To the fullest extent permitted by Section 145 of the General Corporation Law of the State of Delaware, as the same may be amended and supplemented, indemnify any and all persons whom it shall have the power to indemnify under said section from and against any and all of the expenses, liabilities or other matters referred to in or covered by said section, and the indemnification provided for herein shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any By-Law, agreement or vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.”

On March 4, 2005, we amended our filing of Form D (Notice of Sale of Securities Pursuant to Regulation D, Section 4(6), and/or Uniform Limited Offering Exemption) to change the exemption we were relying on to Rule 506 rather than Rule 505 for the sale of our common stock. Under Rule 506, we can raise an unlimited amount of money from any number of “accredited” investors and up to 35 “non-accredited” investors.

6)   During 2004, we paid certain vendors for rent and consulting services in shares of our common stock. The number of shares issued and the price per share for such shares issued are as follows:

7)   As discussed in the Certain Relationships and Related Transactionssection of this prospectus, we were obligated under the terms of a line of credit agreement to Match, Inc. outstanding in the amount of $1,851,299 principal balance and $315,554 in accrued interest at December 31, 2004. Ronald E. Lusk, our chairman, controls Match, Inc. as Trustee of the Ronald E. Lusk Revocable Trust. Additionally, on July 25, 1994, we sold, for proceeds of $2 million, 533,333 shares of 8% cumulative Series A Senior Convertible Preferred Stock with cumulative dividends of $0.30 per annum for each share and conversion rights to common stock at a price of $3.75 per share. Under the terms of the Plan under which we emerged from bankruptcy, Match, Inc., the holder of the Series A Preferred Stock, waived such rights, including voting and conversion rights. No dividends had been paid with respect to this class of stock. At the date of the agreement, the cumulative unpaid dividend with respect to the preferred stock was $1,670,685. Thus, the total liquidation preference of the preferred stock was $3,670,685 as of March 31, 2005.

In contemplation of our private placement of the 6% Convertible Preferred Stock which was completed in May 2005, the placement agent recommended and our board of directors concurred that the Match, Inc. debt and Series “A” Preferred Stock would preclude us from successfully completing the financing transaction. A special committee of independent directors consisting of Directors Robert E. Bachman, Donald R. Harkleroad, and Robert L. Woodson, III (the “Special Committee”) was formed on March 14, 2005 to negotiate with Mr. Lusk the exchange of the Series A Preferred Stock and the Match, Inc. debt for shares of our common stock.

The board of directors (with Mr. Lusk abstaining and one director absent) reviewed the analysis prepared by the Special Committee. Based upon the exchange ratio of $1.725 per share offered by Mr. Lusk with respect to both the preferred stock and the debt, as well as the proposal by Mr. Lusk to reduce the accrued interest on the line of credit by $250,000, the board concluded that the offer was fair to us and voted to approve the transactions contained in the proposal from Mr. Lusk. The common shares issued in exchange for the Series A Preferred Stock and the amount due under the credit agreement totaled 3,254,034 shares, which were issued on May 5, 2005 as follows:

Date	Issuee		No. of Shares		Price per Share		Total
5/5/2005		2 Boys AB Revocable Trust		1,627,017	$	1.725	$	2,806,604
5/5/2005		Ronald E. Lusk Revocable Trust		1,627,017		1.725		2,806,604
				3,254,034			$	5,613,209

8)   On February 10, 2005, we entered into a consulting contract with Equity Group, Inc. (“Equity”) to provide financial public relations and investor relations on behalf of us. In connection therewith, we agreed to issue Equity two warrants to purchase an aggregate of $600,000 worth of shares of our common stock with each warrant having an exercise price to be determined in the future. Such exercise price has been determined to be $0.80 per share. Each warrant will provide for the purchase of $300,000 worth of our common stock. One of the warrants became fully vested upon the signing of the contract. The other warrant will become exercisable upon the first anniversary date of the consulting contract unless terminated earlier.

9)   On February 15, 2005, we entered into a letter agreement with Giuliani Capital Advisors LLC (“GCA”) to engage GCA to provide financial advisory services to us and a to-be-formed entity. The intent of the Joint Venture is to own streetlights and related lighting infrastructure targeting municipalities, public utility corporations, universities, large mall owners, parking lot owners, and other organizations as partners/customers. We issued a warrant to GCA that is exercisable by GCA to purchase up to 1,650,000 shares of our common stock, subject to adjustment in certain circumstances as provided in the warrant. The 1,650,000 shares represented 3.2% of outstanding shares of common stock at February 15, 2005. The warrant has a five-year term and GCA may exercise the warrant in whole or in part at any time during the five-year term. The exercise price for each share of common stock is $.60 per share or $990,000 if GCA were to exercise all 1,650,000 shares under the warrant.

10)   At a meeting of our board of directors held on March 30, 2005, certain individual members of our board of directors and members of senior management agreed to loan us an aggregate of $340,000 on a short-term basis pursuant to the terms of promissory notes from Lighting Science Group and in favor of each of the individual lenders. The members of the board and senior management who agreed to loan us funds and the amounts loaned by each individual are as follows: John A. Collingwood - $100,000, Ronald E. Lusk - $30,000, Stan T. Waldrop - $30,000, Philip N. Lacerte - $30,000, Robert E. Bachman (through USGT Investors L.P.) - $30,000, Donald R. Harkleroad (through the Bristol Company) - $30,000, Robert L. Woodson, III - $30,000, Daryl N. Snadon - $30,000, and the Fredric S. Maxik (through the Phibian S Trust) - $30,000. Mr. Lusk loaned us an additional $15,000 on April 29, 2005 and $5,000 on May 2, 2005. Mr. Snadon loaned us an additional $100,000 on May 3, 2005 and Mr. Harkleroad loaned us an additional $16,000 on May 6, 2005. The board members and officers who loaned us funds in this transaction are collectively referred to as the Lenders. Proceeds from each of the loans were used to fund our continuing operating expenses, including salaries, legal and accounting fees and for working capital purposes and other contingencies. Pursuant to the terms of the notes issued by us to each Lender, eight warrants for 30,000 shares of common stock and one warrant for 100,000 shares of common stock vested on the date of issuance, April 20, 2005. On April 29, 2005 and May 2, 2005, respectively, we issued warrants for 15,000 and 5,000 shares of common stock to Mr. Lusk. On May 3, 2005, we issued a warrant for 100,000 shares of common stock to Mr. Snadon and on May 6, 2005, we issued a warrant for 16,000 shares of common stock to Mr. Harkleroad. All such warrants vested on the date of issuance. The warrants have anti-dilution and exercise price adjustment provisions for dividends and stock splits. Each warrant expires five years from the date of issuance.

11)   On May 12, 2005, we entered into a definitive Securities Purchase Agreement (the “Securities Purchase Agreement”) with Western Reserve Hedged Equity, LP, AG Domestic Convertibles, L.P., A.G. Offshore Convertibles, Ltd., the Gryphon Master Fund, L.P., the GSSF Master Fund, L.P., Xerion Partners I LLC, Xerion Partners II Master Fund Limited, Telemark Asset Management, LLC and certain other accredited investors (collectively referred to as the “Purchasers”) for the private placement of our 6% Convertible Preferred Stock, $.001 par value, pursuant to which the Purchasers have agreed to purchase 2,260,966 shares of the preferred stock at $3.20 per share for an aggregate purchase price of $7,235,086. The Securities Purchase Agreement was executed on May 12, 2005. Additionally, we entered into and executed warrants, a registration rights agreement and lock-up agreements with affiliates and certain stockholders. A certificate of designation that sets forth the rights, preferences, terms and conditions of the preferred stock was filed with the Secretary of State of the State of Delaware on May 10, 2005.

The preferred stock may be converted into shares of common stock. The preferred stock will have an initial conversion price of $0.80 per share of common stock subject to full ratchet anti-dilution provisions. The Purchasers also received warrants to purchase an additional 6,782,889 shares of common stock at an exercise price of $0.96 per share (subject to adjustment pursuant to anti-dilution provisions). The warrants have a term of five years from the closing date. Merriman Curhan Ford & Co. and MRM Capital LP acted as placement agents for this transaction. Warrants to purchase a total of 639,844 shares of common stock at an exercise price of $1.50 per share (subject to adjustment pursuant to anti-dilution provisions) were issued to Merriman and MRM in conjunction with this transaction.

ITEM 28. UNDERTAKINGS

The undersigned registrant hereby undertakes:

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

(i) Include any prospectus required by Section 10(a)(3) of the Securities Act;

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

(iii) Include any additional or changed material information on the plan of distribution;

(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 bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities that remain unsold at the end of the offering.

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

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