Recent Events
 
We develop and sell solutions designed to optimize the RF (Radio Frequency) link within wireless networks. RF link, or Radio link, is the signal between the mobile device (e.g. mobile phone) and the base station. Reverse link is the signal from the mobile device to the base station. Forward link is the signal from the base station to the mobile device. Our array of solutions includes our “AIM” platform (adaptive interference management), the RF² product family (radio frequency fidelity, or RF² ™), services and other solutions, all focused on optimizing RF handling in order to improve system performance and integrate disparate technologies as required by operators. The wireless telecommunications industry continues to promote data services and consolidate with an increased requirement for disparate technologies to co-exist. These are trends that we look to take advantage of with our RF management products.  During January 2008 we completed the acquisition of Clarity Communication Systems Inc., or Clarity.  Clarity provides highly effective, low cost applications for mobile devices, including Push-To-Talk, or PTT, Location-Based Services, or LBS, and a combination of both applications in its Where2Talk, or W2T solution.
 
In 2003 we implemented a shift from manufacturing in-house to an outsourced manufacturing model wherein we supply parts and raw materials to third parties, who then complete the products to our specifications.  Our personnel may be on hand to assist with quality control.  This system allows us to outsource procurement in the future if we choose to do so.  Our products are designed for efficient production in this manner, emphasizing solid-state electronics over mechanical devices with moving parts. The decrease in cost associated with these developments, coupled with enhanced product functionality, have significantly reduced overhead costs since 2002 and allowed us to realize consistently improved margins.  Clarity’s solutions are software applications and thus do not require significant manufacturing operations.

The wireless telecommunications market has experienced significant consolidation activity in recent years, a trend which may continue.  These activities often result in operators attempting to manage and maintain disparate technologies and spectrum assets, and the need to integrate those assets.  In addition, the deployment of data applications is adding to the industry requirement to integrate disparate technologies into base stations and other fixed points of access, resulting in the need to manage multiple wireless signals and keep them from interfering with each other.  We are focused on providing solutions that address these types of requirements and, as a result of this focus, since 2006 we have bid on substantially larger business opportunities than we had in previous years.  These proposals often are accompanied by long approval cycles and up-front product development costs for us.  We believe the potential benefits to outweigh these costs, and expect to continue to bid on these types of business opportunities.  We also continue to pursue an increasing number of smaller projects to complement these larger opportunities.

We announced several significant events during 2007 and the beginning of 2008.  In November of 2007, we entered into a definitive merger agreement, or the Merger Agreement, with Clarity, a company formerly owned by James Fuentes, one of our directors.  In January 2008, we completed the merger and acquired Clarity as our wholly owned subsidiary.  In November 2007, we also saw the departure of our Chief Executive Officer John Thode, and welcomed John Owings to our board of directors in August 2007.  We also announced sales and product developments such as increased international sales and sourcing activities, including the entering into of commercial arrangements with certain partners in Asia, Europe and Latin America in an effort to expand our international operations to take advantage of the re-mining existing spectrum overseas to add data services, among other opportunities.  Further, we announced the expansion of our customer base, and significant new product developments including the launch of our first substantially digital platform, the digital adaptive notch filter within the AIM platform, or dANF, which is designed for use in the PCS (1900 MHz) band and can be configured for other architectures/frequencies.  We also announced the development of the next generation of this solution in the form of the fully digital interference filter, or DIF, platform.  Despite these improvements, the wireless telecommunications industry is subject to risks beyond our control that can negatively impact customer capital spending budgets (as occurred during 2003 and portions of 2007) and/or spending patterns (as occurred during 2004 and portions of 2006).  

As an after-market solutions provider, we have experienced uneven revenue, reflecting the buying patterns of wireless telecommunications carriers. We and other after-market vendors historically have experienced a “fourth quarter effect” in which operators used a disproportionately large percentage of their capital budgets at the end of their fiscal year rather than lose it going forward.  More recently, as operators have embarked on significant projects such as the deployment of and upgrades to data networks, wireless operators have often reallocated funds from their voice networks to other activities, and from fiscal year planning to project planning.  We have been adjusting our product line and sales strategy to try to take advantage of these trends and, thus, realize a higher, more stable revenue stream.

As indicated above, we are pursuing digital technologies and providing solutions on multiple frequencies.  We believe that by producing solutions in digital format we will have appropriate form, cost, and performance factors to extend coverage in the wireless telecommunications realm and greatly increase our available market, both in an expanded reach in the cellular market and new opportunities in the non-cellular market.  We believe that offering solutions at 450 MHz, 1900 MHz, 1700 MHz, 900 MHz, and the traditional US-based cellular 850 MHz bands will be appropriate, both for a broad array of domestic and international opportunities as well as for customers deploying multiple spectrum bands in the same locations.

In order to support our operations by extending maturing debt from our 2002 credit line, as amended, on June 26, 2007, our Company, Manchester Securities Corporation, or Manchester, Alexander Finance, L.P., or Alexander, and our subsidiaries, entered into an amendment to the November 10, 2004 Third Amended and Restated Loan Agreement, as amended, with corresponding amendments to the Fourth Amended and Restated Guaranties and the Fourth Amended and Restated Security Agreement and notes issued by us in favor of the lenders, in conjunction with the restructuring of the notes. Pursuant to the restructuring, the extension of the termination dates and maturity dates for all the notes from August 1, 2007 to August 1, 2009; the interest rate on each of the notes was reduced from 9% to 7% per annum and provision was made for the conversion of the aggregate principal amount outstanding on each of the notes at the election of the lenders, together with all accrued and unpaid interest thereon into shares of our common stock at an initial conversion price of $0.20 per share.  These changes were reflected in amended and restated notes issued to the lenders, or the Notes.  In addition, pursuant to the restructuring, each of the lenders immediately converted $750,000 in principal amount and accrued interest outstanding under the notes each lender held prior to the restructuring into shares of our common stock at a conversion price of $0.18, the 10 day volume weighted average closing price of our common stock on the American Stock Exchange, or AMEX, as of June 21, 2007.
 
In addition, as a condition to completing the merger with Clarity and to pay certain transaction costs, in January 2008 we issued to Alexander a convertible note, or the Additional Note, in the aggregate principal amount of $1,500,000 on the same terms and conditions as the Notes.  Concurrently with the execution of the Additional Note, the lenders waived certain provisions under the line of credit facility, including among other things: (i) the requirement that we use such cash proceeds received in connection with the merger, the issuance of the shares in connection with the merger, the issuance of the Additional Note, and the transactions contemplated thereby to prepay the outstanding Notes issued to the lenders, and (ii) the prohibition to directly or indirectly create, assume, guarantee, or otherwise become or remain directly or indirectly liable with respect to any indebtedness other than the exceptions described therein, upon paying the amount outstanding under Clarity’s line of credit at the closing of the merger.

RISK FACTORS
You should carefully consider the risks described below, along with the other information contained or incorporated by reference in this prospectus, before making an investment decision. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations.
 
Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment.
 
This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus.
 
RISKS RELATED TO OUR OPERATIONS
 
We have a history of losses that raises doubts about our ability to continue as a going concern
 
We were founded in October 1989 and through 1996 we were engaged principally in research and development, product testing, manufacturing, marketing and sales activities.  Since 1996, we have been actively selling products to the marketplace and we continue to develop new products for sale.  We have incurred net losses since inception.  As of September 30, 2007, our accumulated deficit was approximately $169 million.  We have only recently begun to generate revenues from the sale of our ANF and RF² products, having sold more in the two years ended December 31, 2006 (and continuing through 2007) than in the fourteen years of company history prior to 2005.  Although we showed a substantial improvement in revenues and we have indicated the expectation of continued improvement in the future, it is nonetheless possible that we may continue to experience net losses, such as during the third quarter of 2007, and cannot be certain if or when we will become profitable.
 
In addition, Clarity was founded in 1998 and generated profitable results until 2007 when Clarity posted a substantial loss of $2.7 million through the first nine months (ended September 30, 2007) of 2007.  It is possible that the operations related to the Clarity business may continue to experience net losses and cannot be certain if or when Clarity will again become profitable.
 
These conditions raise substantial doubt about our ability to continue as a going concern.  Our consolidated financial statements have been prepared assuming we will continue as a going concern and do not include any adjustments relating to the recoverability of reported assets or liabilities should we be unable to continue as a going concern.
 
If we fail to obtain necessary funds for our operations, we may be unable to maintain or improve on our technology position and unable to develop and commercialize our products
 
To date, we have financed our operations primarily through public and private equity and debt financings, and most recently through several financings with affiliates of our two largest shareholders.  In connection with the acquisition of Clarity, we obtained from one of our existing lenders $1.5 million in financing to fund certain transaction costs.  Further, we may have additional working capital requirements that may require additional financial resources.  As such, we may require additional capital.  We intend to look into augmenting our existing capital position by continuing to evaluate potential short-term and long-term sources of capital whether from debt, equity, hybrid, or other methods.  The primary covenant in our existing debt arrangement involves the right of the lenders to receive debt repayment from the proceeds of new financing activities.  This covenant may restrict our ability to obtain new sources of financing and/or to apply the proceeds of a financing event toward operations until the debt is repaid in full.
 
Our continued existence is therefore dependent upon our continued ability to raise funds through the issuance of our equity securities or borrowings.  Our plans in this regard are to obtain other debt and equity financing until such time as profitable operation and positive cash flow are achieved and maintained.  Although we believe, based on the fact that we have raised funds through sales of common stock and from borrowings over the past several years, that we will be able to secure suitable additional financing for our operations, there can be no guarantee that such financing will continue to be available on reasonable terms, or at all.  
6

 
The actual amount of future funding requirements will depend on many factors, including: the amount and timing of future revenues, the level of product marketing and sales efforts to support our commercialization plans, our expansion of our international operations, the magnitude of research and product development programs, the ability to improve or maintain product margins, the successful integration into our business as well as any other merger and acquisition activity, and the costs involved in protecting patents or other intellectual property.
 
Risks involved in acquisitions, including the risk that we may not successfully integrate the Clarity business or realize the anticipated benefits from the merger, which could adversely affect our business, financial condition and results of operations
 
In the future, we may pursue acquisitions to obtain products, services and technologies that we believe would complement or enhance our current product or services offerings, such as the recent acquisition of Clarity.  There is no assurance that we will be able to successfully integrate the Clarity business, or any future acquired business, into our own.  At the present time, no other definitive agreements or similar arrangements exist with respect to any other acquisition.  An acquisition, such as the merger with Clarity, may not produce the revenue, earnings or business synergies as anticipated and may attach significant unforeseen liabilities, and an acquired product, service or technology might not perform as expected.  Our management could spend a significant amount of time and effort in identifying and completing the acquisition and may be distracted from the operations of the business.  In addition, management would probably have to devote a significant amount of resources toward integrating the acquired business with the existing business, and that integration may not be successful.  The process is resource intensive, both in time and financial resources, and thus incorporates a cost to the company.
 
Failure to attract and retain of key personnel could have a material adverse effect on our business
 
Our success depends on our ability to attract and retain the appropriate personnel needed to operate our business.  During October 2007, we announced the departure of our CEO and our subsequent search for his replacement.  Our success depends, in part, on finding an appropriate person to fill this necessary role within our Company.
 
Additionally, the value of the Clarity acquisition to our stockholders rests in large part on the continuity of the key personnel from the former Clarity organization remaining with us.  While we believe we have devised appropriate incentives to retain former Clarity employees, there can be no guarantee that they will choose to remain with our Company.  Due to the specialized nature of the Clarity business, it may be difficult to locate and hire qualified personnel.  The loss of services of any of our key personnel, or the failure to attract and retain other key personnel, could have a material adverse effect on our business, operating results and financial condition.
 
Our Clarity business is dependent on the acceptance of push-to-talk and location-based services and related applications
 
Increased sales of our Clarity products are dependent on a number of factors, one of which is the acceptance and demand for location-based features and push-to-talk services.  Further, the spending patterns of wireless operators and OEMs is beyond management’s control and depends on a variety of factors, including access to financing, the status of federal, local and foreign government regulation and deregulation, changing standards for wireless technology, the overall demand for wireless services, competitive pressures and general economic conditions.  The expansion of wireless services and applications, and related networks to support them, may take years to complete.  The magnitude and timing of capital spending by these operators for constructing, rebuilding or upgrading their systems significantly impacts the demand for Clarity products.  Any decrease or delay in capital spending patterns in the wireless telecommunications industry, whether because of a general business slowdown or a reevaluation of the prospective demand for data and other services, would delay the build-out of these networks and may significantly harm our business prospects.
 
The indemnification obligations under the Merger Agreement are limited, which means we could have unreimbursed liabilities related to the acquisition
 
Our Company, our officers, directors, employees, stockholders  and other related parties, will be entitled to indemnification in the event of losses resulting from, among other things, breaches of Clarity’s representations and warranties, failure to perform covenants under the Merger Agreement and Clarity tax obligations solely and exclusively as provided in the Merger Agreement, other than for fraud.  Our Company and other indemnified parties will not be entitled to indemnification until the cumulative amount of all losses exceed $150,000, after which such party will only be entitled to any amounts that exceed $150,000.  In addition, the length of time in which our Company and other indemnified parties have a right to bring an indemnification claim and the amount to which a party may be indemnified are subject to certain caps as set forth in the Merger Agreement.  Further, indemnification may be satisfied by withholding Time-Based Shares of Common Stock issuable in connection with the merger, which would not provide us with any cash to either pay or offset the liability that was the subject of the indemnification claim.  Unreimbursed liabilities related to our acquisition of Clarity could have a material adverse effect on our business, operating results and financial condition.
7

Failure to manage our growth may have a material adverse effect on our business
 
Growth may cause a significant strain on our management, operational, financial and other resources.  The ability to manage growth effectively may require us to implement and improve our operational, financial, manufacturing and management information systems and expand, train, manage and motivate employees.  These demands may require the addition of new management personnel and the development of additional expertise by management.  Any increase in resources devoted to product development and marketing and sales efforts could have an adverse effect on financial performance in future fiscal quarters.  If we were to receive substantial orders, we may have to expand current facilities, which could cause an additional strain on our management personnel and development resources.  The failure of the management team to effectively manage growth could have a material adverse effect on our business, operating results and financial condition.  In addition, the recent acquisition of Clarity will require substantial attention and resources in order to integrate Clarity’s operations into our business and distract management from other areas of our business.
 
OTHER BUSINESS RISKS
 
We have limited experience in manufacturing, sales and marketing and are dependent on third party manufacturers
 
For us to be financially successful, we must either manufacture our products in substantial quantities, at acceptable costs and on a timely basis or enter into outsourcing arrangements with qualified manufacturers that will allow us the same result.  Currently, our manufacturing requirements are met by third party contract manufacturers.  The efficient operation of our business will depend, in part, on our ability to have these and other companies manufacture our products in a timely manner, cost-effectively and in sufficient volumes while maintaining the required quality.  Any manufacturing disruption could impair our ability to fulfill orders and could cause us to lose customers.
 
In the event that we are unable to maintain manufacturing arrangements on acceptable terms with qualified manufacturers then we would have to produce our products in commercial quantities in our own facilities.  Although to date we have produced limited quantities of our products for commercial installations and for use in development and customer field trial programs, production of large quantities of our products at competitive costs presents a number of technological and engineering challenges.  We may be unable to manufacture such products in sufficient volume.  We have limited experience in manufacturing, and substantial costs and expenses may be incurred in connection with attempts to manufacture larger quantities of our products.  We may be unable to make the transition to large-scale commercial production successfully.
 
Our sales and marketing experience to date is very limited.  We may be required to further develop our marketing and sales force in order to effectively demonstrate the advantages of our products over other products.  We have recently entered into arrangements with third parties regarding the commercialization and marketing of our products, particularly with respect to our activities in Asia, Europe and Latin America, and we may elect to enter into further such arrangements.  If we enter into such agreements or relationships, we would be substantially dependent upon the efforts of others in deriving commercial benefits from our products.  We may be unable to establish adequate sales and distribution capabilities, we may be unable to enter into marketing arrangements or relationships with third parties on financially acceptable terms, and any such third party may not be successful in marketing our products.  There is no guarantee that our sales and marketing efforts will be successful.
 
Dependence on a limited number of customers may have a material adverse effect on our business
 
Excluding the Clarity business, sales to three customers accounted for at least 94% of our total revenues for 2006, 2005 and 2004, and we expect a similar concentration to be reported for 2007.  During 2006, our top three customers were Verizon Wireless, Alltel Corporation, and Bluegrass Cellular Corporation.  In addition, a significant amount of our technical and managerial resources have been focused on working with these and a limited number of other operators and OEMs.  The loss of any of these large customers might have a material adverse effect on our business, operating results, and financial condition.  Additionally, Clarity also boasts a heavy customer concentration, with its top three customers accounting for nearly 100% of its revenues for 2006 (Alcatel-Lucent Technologies, Autodesk, and Lockheed Martin) and we expect a similar customer concentration disclosure for 2007.
 
We expect that if our products achieve market acceptance, a limited number of wireless service providers and OEMs will account for a substantial portion of revenue during any period.  Sales of many of our products depend in significant part upon the decisions of prospective and current customers to adopt and expand their use of these products.  Wireless service providers, wireless equipment OEMs and our other customers are significantly larger than we are, and are able to exert a high degree of influence over us.  Customers’ orders are affected by a variety of factors such as new product introductions, regulatory approvals, end user demand for wireless services, customer budgeting cycles, inventory levels, customer integration requirements, competitive conditions and general economic conditions.  The failure to attract new customers would have a material adverse effect on our business, operating results and financial condition.

    We expect that if our Clarity products achieve market acceptance, a limited number of wireless service providers and OEMs will account for a substantial portion of revenue during any period.  Sales of many Clarity products depend in significant part upon the decisions of prospective and current customers to adopt and expand their use of these products.  Wireless service providers, wireless equipment OEMs and Clarity’s other customers are significantly larger than we are, and are able to exert a high degree of influence over us in negotiating customer contracts.  Customers’ orders are affected by a variety of factors such as new product introductions, regulatory approvals, end user demand for wireless services, customer budgeting cycles, inventory levels, customer integration requirements, competitive conditions and general economic conditions.  The loss of any such customer or the failure to attract new customers would have a material adverse effect on our business, operating results and financial condition.
We have lengthy sales cycles which could make revenues and earnings inconsistent and difficult to trend
 
Prior to selling products to customers, we may be required to undergo lengthy approval and purchase processes.  Technical and business evaluation by potential customers can take up to a year or more for products based on new technologies.  The length of the approval process is affected by a number of factors, including, among others, the complexity of the product involved, priorities of the customers, budgets and regulatory issues affecting customers.  We may not obtain the necessary approvals or ensuing sales of such products may not occur.  The length of customers’ approval process or delays could make our quarterly revenues and earnings inconsistent and difficult to trend.
 
International operations pose additional risks to our business
 
We are in discussions and have agreements in place with companies in non-U.S. markets to form manufacturing and product development joint ventures and other marketing, distribution or consulting arrangements. We also have agreements with foreign entities for international distribution as well as foreign sources of components to be used in North America.  These agreements and relationships help us optimize our competitive position and cost structure.  There are many such entities that exist, domestically and internationally, that offer similar capabilities, and thus could reduce risk exposure to the loss of such foreign entities. Recently, we have begun to prioritize opportunities in Europe, Asia and Latin America more aggressively, to complement our domestic business model, which will subject our business, operating results and financial condition to additional risks associated with international operations.
 
We believe that non-U.S. markets could provide a substantial source of revenue in the future. However, there are certain risks applicable to doing business in foreign markets that are not applicable to companies doing business solely in the U.S. For example, we may be subject to risks related to fluctuations in the exchange rate between the U.S. dollar and foreign currencies in countries in which we do business.  Further, overseas activities are subject to political and other factors that may adversely affect our ability to do business in certain markets.  In addition, we may be subject to the additional laws and regulations of these foreign jurisdictions, some of which might be substantially more restrictive than similar U.S. ones. Foreign jurisdictions may also provide less patent protection than is available in the U.S., and we may be less able to protect our intellectual property from misappropriation and infringement in these foreign markets.
 
We are dependant on limited sources of supply
 
Certain parts and components used in our RF products are only available from a limited number of sources.  Our reliance on these limited source suppliers exposes us to certain risks and uncertainties, including the possibility of a shortage or discontinuation of certain key components and reduced control over delivery schedules, manufacturing capabilities, quality and costs.  Any reduced availability of such parts or components when required could materially impair the ability to manufacture and deliver products on a timely basis and result in the cancellation of orders, which could have a material adverse effect on our business, operating results and financial condition.
 
In addition, the purchase of certain key components involves long lead times and, in the event of unanticipated increases in demand for our products, we may be unable to manufacture products in quantities sufficient to meet customers’ demand in any particular period.  We have few guaranteed supply arrangements with our limited source suppliers, do not maintain an extensive inventory of parts or components, and customarily purchase parts and components pursuant to actual or anticipated purchase orders placed from time to time in the ordinary course of business.
 
Related to this topic, we produce substantially all of our products through third-party contract manufacturers.  Like raw materials, the elimination of any of these entities or delays in the fulfillment process, for whatever reason, may impact our ability to fulfill customer orders on a timely basis and may have a material adverse effect on our business, operating results, or financial condition.
 
To satisfy customer requirements, we may be required to stock certain long lead-time parts and/or finished product in anticipation of future orders, or otherwise commit funds toward future purchase.  The failure of such orders to materialize as forecasted could limit resources available for other important purposes or accelerate the requirement for additional funds.  In addition, such excess inventory could become obsolete, which would adversely affect financial performance.  Business disruption, production shortfalls or financial difficulties of a limited source supplier could materially and adversely affect us by increasing product costs or reducing or eliminating the availability of such parts or components.  In such events, the inability to develop alternative sources of supply quickly and on a cost-effective basis could materially impair the ability to manufacture and deliver products on a timely basis and could have a material adverse effect on our business, operating results and financial condition.
9

Failure of products to perform properly might result in significant warranty expenses
 
In general, our products carry a warranty of one or two years, limited to replacement of the product or refund of the cost of the product.  In addition, we offer our customers extended warranties.  Repeated or widespread quality problems could result in significant warranty expenses and/or the loss of customer confidence.  The occurrence of such quality problems could have a material adverse effect on our business, operating results and financial condition.
TECHNOLOGY AND MARKET RISKS
 
We are dependent on wireless telecommunications
 
The principal target market for our products is wireless telecommunications.  The devotion of substantial resources to the wireless telecommunications market creates vulnerability to adverse changes in this market.  Adverse developments in the wireless telecommunications market, which could come from a variety of sources, including future competition, new technologies or regulatory decisions, could affect the competitive position of wireless systems.  Any adverse developments in the wireless telecommunications market may have a material adverse effect on our business, operating results and financial condition.
 
We are dependent on the enhancement of existing networks and the build-out of next-generation networks, and the capital spending patterns of wireless network operators
 
Increased sales of products are dependent on a number of factors, one of which is the build-out of next generation (3G and 4G) enabled wireless communications networks as well as enhancements of existing infrastructure.  Building wireless networks is capital intensive, as is the process of upgrading existing equipment.  Further, the capital spending patterns of wireless network operators is beyond management’s control and depends on a variety of factors, including access to financing, the status of federal, local and foreign government regulation and deregulation, changing standards for wireless technology, the overall demand for wireless services, competitive pressures and general economic conditions.  The build-out of next-generation networks may take years to complete.  The magnitude and timing of capital spending by these operators for constructing, rebuilding or upgrading their systems significantly impacts the demand for our products.  Any decrease or delay in capital spending patterns in the wireless communication industry, whether because of a general business slowdown or a reevaluation of the prospective demand for data and other services, would delay the build-out of these networks and may significantly harm business prospects.
 
Our success depends on the market’s acceptance of our products
 
Our RF products have not been sold in very large quantities and a sufficient market may not develop for these products.  Similarly, Clarity has derived the majority of its historical revenue from custom product development (contract engineering) and not from product sales to customers.  Customers establish demanding specifications for performance, and although we believe we have met or exceeded these specifications to date, there is no guarantee that the wireless service providers will elect to use these solutions to solve their wireless network problems.  Although we have enjoyed substantial revenue growth during recent years relative to prior years in company history, there is no assurance that we will continue to receive orders from these customers.
 
Intense competition, and continued consolidation in the wireless telecommunications industry could create stronger competitors and harm our business
 
The wireless telecommunications applications market is very competitive.  Many of these companies have substantially greater financial resources, larger research and development staffs and greater manufacturing and marketing capabilities than we do.  Our products compete directly with products which embody existing and future competing commercial technologies.  Other emerging wireless technologies may also provide similar functionality, potentially at lower prices and/or superior performance, and may therefore compete with our products.  Failure of our products to improve performance sufficiently, reliably, or at an acceptable price or to achieve commercial acceptance or otherwise compete with existing and new technologies, would have a material adverse effect on our business, operating results and financial condition.
 
Rapid technological change and future competitive technologies could negatively affect our operations
 
The field of telecommunications is characterized by rapidly advancing technology.  Our success will depend in large part upon our ability to keep pace with advancing our high performance RF technology and efficient, readily available low cost materials technologies as well as our ability to keep pace with advancing our solutions in light of applications and services offered by competitors.  Rapid changes have occurred, and are likely to continue to occur, in the development of wireless telecommunications.  Development efforts may be rendered obsolete by the adoption of alternative solutions to current wireless operator problems or by technological advances made by others, which could have a material adverse effect on our business, operating results and financial condition.

RISKS RELATED TO OUR COMMON STOCK AND CHARTER PROVISIONS
 
Volatility of common stock price
 
The market price of our common stock, like that of many other high-technology companies, has fluctuated significantly and is likely to continue to fluctuate in the future.  Since January 1, 2007 and through January 15, 2008, the price of our common stock has ranged from a low of $0.13 per share to a high of $0.35 per share.  Announcements by us or others regarding the receipt of customer orders, quarterly variations in operating results, acquisitions or divestitures, additional equity or debt financings, results of customer field trials, scientific discoveries, technological innovations, litigation, product developments, patent or proprietary rights, government regulation and general market conditions may have a significant impact on the market price of our common stock.  In addition, fluctuations in the price of our common stock could affect our ability to maintain the listing of our common stock on AMEX.
The issuance of additional shares of common stock will result in dilution to our existing stockholders
 
If we issue the full number of shares of common stock pursuant to the merger with Clarity and in connection with our June 2007 debt restructuring, we will be issuing up to approximately 79.9 million additional shares of Common Stock, or approximately 36% of the total number of shares currently outstanding as of January 15, 2008.  If stockholders approve the issuance of common stock upon conversion of the $1.5 million in notes issued pursuant to the financing obtained in connection with the merger with Clarity, and if we issue the full number of shares issuable pursuant to this transaction, we will be issuing up to approximately 8.4 million additional shares of common stock, or approximately 4% of the total number of shares currently outstanding as of January 15, 2008.  As a result, these issuances will be dilutive to existing stockholders and may have an adverse effect on the market value of our common stock.
 
Further, as of January 15, 2008, we had outstanding options to purchase 4.9 million shares of common stock at a weighted average exercise price of $0.41 per share (fewer than 0.1 million of which have not yet vested) issued to employees, directors and consultants pursuant to the 2003 Equity Incentive Plan and its predecessor 1993 Stock Option Plan, as amended, the merger agreement with Spectral Solutions, and individual agreements with management and directors.  In addition, on the same date we had 3.6 million unvested shares of restricted stock outstanding.  In order to attract and retain key personnel, we may issue additional securities, including grants of restricted shares, in connection with or outside our company employee benefit plans, or may lower the price of existing stock options.  The exercise of options and notes for common stock and the issuance of additional shares of common stock, shares of restricted stock and/or rights to purchase common stock at prices below market value would be dilutive to existing stockholders and may have an adverse effect on the market value of our common stock.
 
As a result of the issuances described above, the sale of a substantial number of shares of our common stock, or the perception that such sales could occur, could adversely affect the market price for our common stock.  It could also impair our ability to raise money through the sale of additional shares of common stock or securities convertible into shares of our common stock.
 
Concentration of our stock ownership
 
At the time of this filing, officers, directors and principal stockholders (holding greater than 5% of outstanding shares) together control more than 50% of the outstanding voting power on a fully diluted basis.  The two largest stockholders, along with their affiliates, are also our lenders, holding all of our outstanding debt instruments.  Consequently, these stockholders, if they act together, would be able to exert significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions.  In addition, this concentration of ownership may delay or prevent a change of control of us, even if such a change may be in the best interests of our stockholders.  The interests of these stockholders may not always coincide with our interests or the interests of other stockholders.  Accordingly, these stockholders could cause us to enter into transactions or agreements that we would not otherwise consider.
 
Certain provisions in our charter documents have an anti-takeover effect
 
There exist certain mechanisms that may delay, defer or prevent such a change of control.  For instance, our Certificate of Incorporation and By-Laws provide that (i) our Board of Directors has authority to issue series of our preferred stock with such voting rights and other powers as the Board of Directors may determine and (ii) prior specified notice must be given by a stockholder making nominations to the Board of Directors or raising business matters at stockholders meetings.  The effect of the anti-takeover provisions in our charter documents may be to deter business combination transactions not approved by our Board of Directors, including acquisitions that may offer a premium over market price to some or all stockholders.
 
The reporting requirements of a public company could result in significant cost to us and divert attention from other activities
 
As a public company, we are required to comply with various reporting obligations.  These obligations change from time to time, and currently include full compliance with Section 404 of the Sarbanes-Oxley Act for our fiscal year ended December 31, 2007.  The process of achieving full compliance might involve the commitment of significant resources, including substantial levels of management attention.  If we fail to comply with the reporting obligations of the Exchange Act and Section 404 of the Sarbanes-Oxley Act, or if we fail to achieve and maintain adequate internal controls over financial reporting, our business, results of operations and financial condition, and investors’ confidence in us, could be materially adversely affected.
11

    As a public company, we are required to comply with the periodic reporting obligations of the Exchange Act, including preparing annual reports, quarterly reports and current reports.  Our failure to prepare and disclose this information in a timely manner could subject us to penalties under federal securities laws, expose us to lawsuits and restrict our ability to access financing.  In addition, we are required under applicable law and regulations to integrate our systems of internal controls over financial reporting.  We plan to evaluate our existing internal controls with respect to the standards adopted by the Public Company Accounting Oversight Board.  During the course of our evaluation, we may identify areas requiring improvement and may be required to design enhanced processes and controls to address issues identified through this review.  This could result in significant delays and cost to us and require us to divert substantial resources, including management time, from other activities.
LEGAL RISKS
 
Intellectual property and patent protection and infringement may be costly
 
Our success will depend in part on our ability to obtain patent protection for our products and processes, to preserve trade secrets and to operate without infringing upon the patent or other proprietary rights of others and without breaching or otherwise losing rights in the technology licenses upon which any of our products are based.  We have applied for patents for inventions developed internally and acquired patent rights in connection with the purchase of the Adaptive Notch Filtering business unit of Lockheed Martin Canada, now demonstrated in our AIM platform.  One of the patents is jointly owned with Lucent Technologies, Inc. (now Alcatel-Lucent Technologies)  We believe there are a large number of patents and patent applications covering RF products and other products and technologies that we are pursuing.  Accordingly, the patent positions of companies using RF technologies, including us, are uncertain and involve complex legal and factual questions.  The patent applications filed by us or others may not result in issued patents or the scope and breadth of any claims allowed in any patents issued to us or others may not exclude competitors or provide competitive advantages.  In addition, patents issued to us, our subsidiaries or others may not be held valid if subsequently challenged or others may claim rights in the patents and other proprietary technologies owned or licensed by us.  Others may have developed, or may in the future develop, similar products or technologies without violating any of our proprietary rights.  Furthermore, the loss of any license to technology that we might acquire in the future may have a material adverse effect on our business, operating results and financial condition.
 
Some of the patents and patent applications owned by us are subject to non-exclusive, royalty-free licenses held by various U.S. governmental units.  These licenses permit these U.S. government units to select vendors other than us to produce products for the U.S. Government, which would otherwise infringe our patent rights that are subject to the royalty-free licenses.  In addition, the U.S. Government has the right to require us to grant licenses (including exclusive licenses) under such patents and patent applications or other inventions to third parties in certain instances.
 
Older patent applications in the U.S. are currently maintained in secrecy until patents are issued.  In foreign countries and for newer U.S. patent applications, this secrecy is maintained for a period of time after filing.  Accordingly, publication of discoveries in the scientific literature or of patents themselves or laying open of patent applications in foreign countries or for newer U.S. patent applications tends to lag behind actual discoveries and filing of related patent applications.  Due to this factor and the large number of patents and patent applications related to RF materials and technologies, and other products and technologies that we are pursuing, comprehensive patent searches and analyses associated with RF technologies and other products and technologies that we are pursuing are often impractical or not cost-effective.  As a result, patent and literature searches cannot fully evaluate the patentability of the claims in our patent applications or whether materials or processes used by us for our planned products infringe or will infringe upon existing technologies described in U.S. patents or may infringe upon claims in patent applications made available in the future.  Because of the volume of patents issued and patent applications filed relating to RF technologies and other products and technologies that we are pursuing, we believe there is a significant risk that current and potential competitors and other third-parties have filed or will file patent applications for, or have obtained or will obtain, patents or other proprietary rights relating to materials, products or processes used or proposed to be used by us.  In any such case, to avoid infringement, we would have to either license such technologies or design around any such patents.  We may be unable to obtain licenses to such technologies or, if obtainable, such licenses may not be available on terms acceptable to us or we may be unable to successfully design around these third-party patents.
 
Our participation in litigation or patent office proceedings in the U.S. or other countries to enforce patents issued or licensed to us, to defend against infringement claims made by others or to determine the ownership, scope or validity of the proprietary rights of us and others, could result in substantial cost to, and diversion of effort by, us.  The parties to such litigation may be larger, better capitalized than we are and better able to support the cost of litigation.  An adverse outcome in any such proceedings could subject us to significant liabilities to third parties, require us to seek licenses from third parties and/or require us to cease using certain technologies, any of which could have a material adverse effect on our business, operating results and financial condition.
 
Litigation may be costly and divert management’s attention
 
We have no active lawsuits, or any pending or threatened to the best of our knowledge.  The act of defending against any potential claim may be costly and divert management attention.  If we are not successful in defending against whatever claims and charges may be made against us in the future, there may be a material adverse effect on our business, operating results and financial condition.
12

Government regulations may have a material adverse effect on our business
 
Although we believe that our wireless telecommunications products themselves are not subject to licensing by, or approval requirements of, the FCC, the operation of base stations, wireless operators, and OEMs are subject to FCC licensing and the radio equipment into which our products would be incorporated is subject to FCC approval.  Base stations and the equipment marketed for use therein must meet specified technical standards.  The ability to sell our wireless telecommunications products is dependent on the ability of wireless base station equipment manufacturers and wireless base station operators to obtain and retain the necessary FCC approvals and licenses.  In order for them to be acceptable to base station equipment manufacturers and to base station operators, the characteristics, quality and reliability of our base station products must enable them to meet FCC technical standards.  We may be subject to similar regulations of foreign governments.  Any failure to meet such standards or delays by base station equipment manufacturers and wireless base station operators in obtaining the necessary approvals or licenses could have a material adverse effect on our business, operating results and financial condition.  In addition, certain RF filters are on the U.S. Department of Commerce’s export regulation list.  Therefore, exportation of such RF filters to certain countries may be restricted or subject to export licenses.
 
We are subject to governmental labor, safety and discrimination laws and regulations with substantial penalties for violations.  In addition, employees and others may bring suit against us for perceived violations of such laws and regulations.  Defending against such complaints could result in significant legal costs for us.  Although we endeavor to comply with all applicable laws and regulations, we may be the subject of complaints in the future, which could have a material adverse effect on our business, operating results and financial condition.
 
Environmental liability may involve substantial expenditures
 
Certain hazardous materials may be used in research, development and to the extent of any manufacturing operations.  As a result, we are subject to stringent federal, state and local regulations governing the storage, use and disposal of such materials.  It is possible that current or future laws and regulations could require us to make substantial expenditures for preventive or remedial action, reduction of chemical exposure, or waste treatment or disposal.  We believe we are in material compliance with all environmental regulations and to date have not had to incur significant expenditures for preventive or remedial action with respect to the use of hazardous materials.
 
However, our operations, business or assets could be materially and adversely affected by the interpretation and enforcement of current or future environmental laws and regulations.  In addition, although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, there is the risk of accidental contamination or injury from these materials.  In the event of an accident, we could be held liable for any damages that result.  Furthermore, the use and disposal of hazardous materials involves the risk that we could incur substantial expenditures for such preventive or remedial actions.  The liability in the event of an accident or the costs of such actions could exceed available resources or otherwise have a material adverse effect on the business, results of operations and financial condition.  We carry property and worker’s compensation insurances in full force and effect through nationally known carriers which include pollution cleanup or removal and medical claims for industrial incidents.
 
USE OF PROCEEDS
 
We will not receive any proceeds from the sale by the selling stockholders of our common stock. The selling stockholders will receive all of the net proceeds from the sale of the shares.
 
SELLING STOCKHOLDERS
 
The 93,335,695 shares of our common stock registered for public resale pursuant to this prospectus and listed under the column “Number of Shares Being Offered” includes (i) 58,492,461 shares issuable upon conversion, for both principal and interest, of the Notes in the aggregate principal amounts of approximately $10.2 million that we issued to our lenders in connection with the restructuring our outstanding debt with our lenders, (ii) 8,333,334 shares issued to our lenders in connection with the debt restructuring and the initial conversion by each lender of an aggregate of $750,000 of previously issued notes, (iii) 25,474,064 shares issued or issuable to Mr. James Fuentes, one of our directors and an employee of our Company, in connection with the acquisition of Clarity, and (iv) 1,035,836 shares issued or issuable to the Non-Continuing Rightsholders in connection with the acquisition of Clarity. We are required to keep each registration statement relating to the shares covered by this prospectus effective until the earlier of (a) the date on which all the holders of the registered shares have completed the sales or distribution of such shares or, (b) until such shares may be sold by such holders under Rule 144(k) (provided that our transfer agent has accepted an instruction from us to such effect).
 
The shares listed under the column “Number of Shares Being Offered” represents the number of shares that may be sold by each selling stockholder pursuant to this prospectus. Pursuant to Rule 416 under the Securities Act, the registration statement of which this prospectus is a part also covers any additional shares of our common stock which become issuable in connection with such shares because of any stock dividend, stock split, recapitalization or other similar transaction effected without the receipt of consideration which results in an increase in the number of outstanding shares of our common stock.
 
We do not know when or in what amounts the selling stockholders may offer shares for sale. The selling stockholders may or may not sell all or any of the shares offered by this prospectus. We may amend or supplement this prospectus from time to time to update the disclosure set forth herein. Because the selling stockholders may offer all or some of the shares pursuant to this offering, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares that will be held by the selling stockholders after completion of the offering, we cannot estimate the number of the shares that will be held by the selling stockholders after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the shares covered by this prospectus will be held by the selling stockholders.
 
The following table sets forth, to our knowledge, certain information regarding the beneficial ownership of the shares of common stock held by the selling stockholders as of the date hereof.  We have assumed that each selling stockholder is issued the maximum number of shares of common stock issuable that the selling stockholder may receive either (i) with respect to the lenders, upon conversion of the Notes, or (ii) , with respect to Mr. Fuentes and the Non-Continuing Rightsholders, upon achievement of certain time-based and market capitalization-based milestones in connection with the merger.  Beneficial ownership is calculated based upon Securities and Exchange Commission requirements and is not necessarily indicative of beneficial ownership for any other purpose. Unless otherwise indicated below, the selling stockholders named in this table have sole voting and investment power with respect to all of their respective shares beneficially owned. The presentation is based on approximately 222 million shares of our common stock outstanding as of January 15, 2008:

We prepared this table based on the information supplied to us by the selling stockholders named in the table.
 
Line of Credit Financing
 
During October 2002, we entered into an uncommitted line of credit with two of the selling stockholders, Alexander Finance, L.P., and Manchester Securities Corporation, who are affiliates of our two largest stockholders. This line provided up to $4 million to be borrowed by us, and we borrowed $1 million during October 2002 upon completion of the transaction. $1 million was borrowed during November 2002 and a third borrowing of $1 million occurred in March 2003. This line is uncommitted, such that each new borrowing under the facility was subject to the approval of the lenders.
 
Borrowings on this line bore an initial interest rate of 9.5% and are collateralized by all our assets. Outstanding loans under this agreement are required to be repaid on a priority basis should we receive new funding from other sources. Additionally, the lenders were entitled to receive warrants to the extent funds are drawn down on the line. The warrants bore a strike price of $0.20 per share of common stock and expired on April 15, 2004. The credit line was to mature and be due, including accrued interest thereon, on March 31, 2004. Warrants to purchase 10 million shares of common stock were issued in connection with the borrowings under the line of credit during the year ended December 31, 2002. No other warrants were issued in connection with March 2003 borrowing under the line of credit.
 
On October 24, 2003, we and the lenders amended the terms of the line of credit agreement to reflect: (i) an increase in the aggregate commitment of the lenders from $4,000,000 to $6,000,000; (ii) the elimination of warrant issuances from future drawdowns; (iii) interest on future loans would bear interest at the rate of 14% per annum; (iv) that future loans mature on October 31, 2004; (v) and that future loans be subject to the discretion of the lenders. We borrowed $1,000,000 from the line of credit agreement upon execution of the amendment. During February 2004, the lenders exercised all of their warrants, purchasing 10,000,000 shares of common stock. We received the $2,000,000 aggregate strike price for the exercise of these warrants.
 
During July 2004, we and our lenders agreed to increase the aggregate loan commitments under the credit line from $6,000,000 to $6,500,000. Simultaneously, we drew the remaining $1,500,000 of the financing.
 
During November 2004, we and our lenders agreed to increase the line of credit up to an additional $2 million to an aggregate loan commitment of $8,500,000, $1 million of which was drawn immediately by us with the remaining $1 million available to be drawn upon our request and subject to the approval of the lenders. The remaining $1 million was subsequently drawn down in January 2005.
 
During February 2005, the consolidated credit line was extended until April 1, 2006. Interest during the extension period is to be charged at 9%.
 
During July 2005 we issued and sold in a private placement to affiliates of our lenders 20,000,000 shares of common stock at a per share price of $0.22, or an aggregate of $4,400,000 in proceeds to us.  In connection with this financing, the lenders agreed to extend the maturity date of the credit line until August 1, 2007 and to waive the provision of the loan agreement whereby they would be entitled to receive the proceeds of any issuance of capital stock to prepay the outstanding debt. Pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, these entities also remitted approximately $0.6 million in profits from sales of Company common stock during the six months preceding this financing.
 
On June 26, 2007, our Company, our subsidiaries and the lenders entered into an amendment to the November 10, 2004 Third Amended and Restated Loan Agreement, as amended, with corresponding amendments to the Fourth Amended and Restated Guaranties and the Fourth Amended and Restated Security Agreement and notes, or collectively, the Amendments to the Loan Documents, issued by the Company in favor of the lenders to restructure our line of credit arrangement.  In conjunction with the debt restructuring, we issued amended and restated notes, or the Notes, in an aggregate principal amount, including accrued interest on the notes, of approximately $10.2 million to replace all of the existing notes under our line of credit arrangement and reflect the amendments to the Loan Documents, including: (i) the extension of the termination dates and maturity dates for all the notes from August 1, 2007 to August 1, 2009; (ii) the reduction of the interest rate on each of the notes from 9% to 7% per annum; (iii) provision for the conversion of the aggregate principal amount outstanding on each of the Notes at the election of the lenders, together with all accrued and unpaid interest thereon into shares of the our common stock at an initial conversion price of $0.20 per share.  In addition, pursuant to the amendments to the Loan Documents, each of Manchester Securities Corporation and Alexander Finance L.P. immediately converted $750,000 in principal amount and accrued interest outstanding under the notes each lender held prior to the restructuring, into shares of the our common stock at a conversion price of $0.18, the 10 day volume weighted average closing price of the our common stock on the American Stock Exchange as of June 21, 2007.
 
In conjunction with this credit line restructuring, we entered into a registration rights agreement with the selling stockholders which required us to use our best efforts to effect the registration of the resale of the shares issuable to the selling stockholders upon conversion of their Notes. If the shares of common stock issued or issuable upon conversion of the Notes are not registered under the registration rights agreement by the 15 month anniversary of the issuance date of the Notes, then the then-current interest rate will increase by a rate of 1% per annum each month thereafter until these shares are registered, up to the default rate of the lower of 20% per annum or the highest amount permitted by law.  In addition, the registration rights agreement contains other customary covenants, including registration delay payments under certain events for failing to maintain the effectiveness of a registration statement covering the resale of the shares of common stock issued or issuable upon conversion of the Notes.
 
As a condition to the merger with Clarity, we obtained financing, or the Financing, in an amount equal to $1,500,000 to (i) pay certain transaction expenses incurred in connection with the merger and (ii) pay off the amount outstanding under Clarity’s line of credit agreement (as described below). Pursuant to the Financing, on January 3, 2008, we issued a new note to Alexander in aggregate principal amount of $1.5 Million. The note will mature August 1, 2009, bear interest of 7% per annum and be convertible, together with all accrued and unpaid interest thereon, into shares of our common stock at an initial conversion price of $0.20 per share. The note contains substantially similar terms and conditions as the Amended and Restated Notes previously issued to Alexander and Manchester and described above. The transaction was structured as a private placement of securities pursuant to Section 4(2) of the Securities Act and Rule 506 promulgated thereunder.
 
In connection with the Financing, our Company, our lenders, Spectral Solutions, Inc. and Illinois Superconductor Canada Corporation entered into an Amendment to and Waiver and Consent Under the Loan Documents pursuant to which the lenders waived certain provisions under the line of credit facility, including among other things: (i) the requirement under our existing line of credit arrangement to use such cash proceeds received in connection with the merger, the issuance of the shares in connection with the merger, the issuance of the note, and the transactions contemplated thereby to prepay the outstanding Notes issued to the lenders, and (ii) the prohibition to directly or indirectly create, assume, guarantee, or otherwise become or remain directly or indirectly liable with respect to any indebtedness other than the exceptions described therein, upon paying the amount outstanding under Clarity’s line of credit at the closing of the merger.
 
Before Alexander may exercise its right to convert the note into shares of our common stock, we are required to be able to issue these shares pursuant to AMEX rules as well as to obtain the approval of AMEX to list the shares on AMEX.  We are required to obtain these approvals within one year of the issuance date of the note. In the event that these required approvals are not obtained by that time, then the interest rate on the note will increase to a rate of 15% per annum. If the shares are not registered under the registration rights agreement, as described below, by the 15 month anniversary of the issuance date of the note, then the then-current interest rate will increase by a rate of 1% per annum each month thereafter until the shares are registered, up to the default rate of the lower of 20% per annum or the highest amount permitted by law. We intend to seek the approval of our stockholders for the issuance of these shares during our Annual Shareholder Meeting which is expected to occur during June 2008.
 
The conversion rate of the note is subject to customary anti-dilution protections. The note does not contain market or trading-based ratchet or reset provisions. We have the right to redeem the note in full in cash at any time beginning June 26, 2009.
 
The note is secured on a first priority basis by all of our intangible and tangible property and assets, including the assets acquired from Clarity in the merger. Payment of the note is guaranteed by ISCO’s Clarity subsidiary.
 
In connection with Financing, we entered into a registration rights agreement with Alexander. Pursuant to the registration rights agreement, we are required to file a registration statement under the Securities Act covering the resale of the shares of common stock issuable upon conversion of the note with the Securities and Exchange Commission within 30 days after both of the stockholders’ and AMEX approvals have occurred. The registration rights agreement contains customary covenants, including registration delay payments, in addition to the interest rate increases under the note described above, under certain events for failing to maintain the effectiveness of a registration statement covering the resale of the shares of common stock issuable upon conversion of the note.

Convertible Debt
 
During June 2006, we entered into a Securities Purchase Agreement and Notes with two of the selling stockholders, who are our lenders under the existing line of credit facility described above, pursuant to which, each selling stockholder agreed to loan us $2,500,000, or an aggregate of $5,000,000, in convertible debt.
 
The notes mature on June 22, 2010 and bear an interest rate of 5% due at maturity. Both the principal amount and any accrued interest on the notes are convertible into shares of our common stock at a rate of $0.33 per share. The conversion rate of the notes is subject to customary anti-dilution protections, provided that the number of additional shares of common stock issuable as a result of changes to the conversion rate is capped so that the aggregate number of shares of common stock issuable upon conversion of the notes will in no event exceed 19.99% of the aggregate number of shares of common stock presently issued and outstanding. The notes do not contain market or trading-based ratchet or reset provisions.  Under a related registration rights agreement with the lenders, we registered for resale on Form S-3 (Reg. No. 333-136612) under the Securities Act 19,000,000 shares of our common stock.
 
The notes are secured on a first priority basis by all of our intangible and tangible property and assets. Payment of the notes was initially guaranteed by our two subsidiaries, Spectral Solutions, Inc. and Illinois Superconductor Canada Corporation. Concurrently with the execution of the Securities Purchase Agreement, the selling stockholders, as the lenders of our existing line of credit arrangement, waived their right under that facility to receive the financing proceeds from the issuance of the notes, allowing us to use the funds for product development or general working capital purposes.  Following the closing of the merger with Clarity, we dissolved Spectral Solutions, Inc. and Illinois Superconductor Canada Corporation, have made Clarity a guarantor of our payment of the notes, and included Clarity’s assets as a part of the security on the notes.  The dissolved entities have been inactive for a number of years, with no assets or operations.
 
Transactions with James Fuentes
 
In November 2007, our Company, Clarity and James Fuentes (for himself and as representative of Clarity’s rightsholders) entered into an Agreement and Plan of Merger, or the Merger Agreement, pursuant to which we would acquire Clarity in a merger in which Clarity would become a wholly-owned subsidiary of our Company. The merger was completed in January 2008.
 
Pursuant to the Merger Agreement, we will issue up to an aggregate of 40 million shares of our common stock in exchange for all of Clarity’s stock, which was held entirely by Mr. Fuentes, and satisfaction of the rights under Clarity’s Non-Qualified Phantom Stock Plan and Clarity’s At-Risk Compensation Plans owed to Mr. Fuentes and Clarity rightsholders. Of the total number of shares we may issue in the merger, 20 million shares were issued at the closing of the merger, 2.5 million shares will be issuable on each of the first and second anniversaries of closing, or the Time-Based Shares, (subject any indemnification claims pursuant to the Merger Agreement and continued employment by former Clarity rightsholders), and 3.75 million shares will be issuable on each of the first dates on which our equity market capitalization first equals or exceeds $125,000,000, $175,000,000, $225,000,000 and $275,000,000 within the three year period after closing of the merger for at least 40 of the 45 consecutive trading days our market capitalization equals these thresholds. The exact number of shares issuable to Mr. Fuentes and the rightsholders will depend on the future market capitalization of the company, whether any of the Time-Based Shares are used to satisfy indemnification claims and whether one or more rightsholders forfeit their shares because their employment with our Company following the closing of the merger is terminated.
 
Mr. Fuentes is allocated approximately 63% of the Shares. No single rightsholder would be allocated more than 3% of the shares. Assuming Mr. Fuentes is issued all of the shares he is eligible to receive in connection with the merger, Mr. Fuentes would beneficially own approximately 11% of our outstanding common stock on a fully-diluted basis, although the number of shares he beneficially owns would decrease if he were to dispose of shares pursuant to this prospectus or otherwise.
 
We paid off the amount of Clarity’s outstanding line of credit at closing, which was approximately $1.2 million.  In addition, we reimbursed certain professional advisors of Clarity up to an aggregate of $375,000 for fees and expenses related to the merger.
 
Our Company, our officers, directors, employees, stockholders, advisers, agents, affiliates (including the surviving corporation in the merger), successors, heirs, permitted assigns and representatives, each, an ISCO Indemnified Party, are entitled to indemnification in the event of losses resulting from, among other things, breaches of Clarity’s representations and warranties, failure to perform covenants under the Merger Agreement and Clarity tax obligations solely and exclusively as provided in the Merger Agreement, other than for fraud. The ISCO Indemnified Parties are not be entitled to indemnification until the cumulative amount of all losses pursuant to indemnification claims exceed $150,000, after which the ISCO Indemnified Parties are only entitled to any amounts that exceed $150,000.
 
The length of time in which to bring an indemnification claim and the amount by which an ISCO Indemnified Party may be indemnified are subject to certain caps as follows:
 
(i) for breaches of representations, or the General Representations, other than Two-Year Representations or Three Year Representations (as described below), any losses entitling an ISCO Indemnified Party to indemnification would be satisfied out of up to an aggregate of 2,000,000 Time-Based Shares. After the Time-Based Shares that vest one year after the closing of the merger, or the First Time-Based Shares, are distributed, the ISCO Indemnified Parties would have no further right to receive indemnification with respect to General Representations;
 
(ii) ISCO Indemnified Parties’ right to receive indemnification for breaches of representations relating to due organization, no conflict with law, no conflict with agreements, necessary consents and brokers, or collectively, the Two-Year Representations, would be satisfied out of the Time-Based Shares; provided that (x) a portion of the First Time-Based Shares will also be available to satisfy other indemnification rights of the ISCO Indemnified Parties, (y) once the First Time-Based Shares are distributed, the ISCO Indemnified Parties would have no further right to use such First Time-Based Shares to satisfy indemnification claims with respect to the Two-Year Representations, and (z) once the Time-Based Shares are fully distributed, the ISCO Indemnified Parties would have no further right to receive indemnification with respect to the Two-Year Representations; and
 
17

 
 
(iii) ISCO Indemnified Parties’ right to receive indemnification for (x) breaches of representations relating to Clarity’s capitalization, authority, no conflict with charter documents, and taxes, or collectively the Three-Year Representations, (y) claims by current and former security holders, and (z) tax obligations would be satisfied first out of the Time-Based Shares. If the Time-Based Shares are not sufficient to satisfy these claims, Mr. Fuentes would be obligated to satisfy the remaining amounts of any such claims (A) brought in the first year after closing of the merger up to an aggregate liability equal to the lesser of $3,000,000 and 75% of Mr. Fuentes’ Share Value (as defined in the Merger Agreement) less the aggregate value of Time-Based Shares already used to satisfy prior indemnification claims, or the First Year Cap, (B) brought in the second year after closing of the merger up to an aggregate liability equal to the lesser of $2,000,000 and 50% of Mr. Fuentes’ Share Value less the aggregate value of Time-Based Shares already used to satisfy prior indemnification claims, or the Second Year Cap and (C) brought in the third year after closing of the merger up to an aggregate liability equal to the lesser of $1,000,000 and 25% of Mr. Fuentes’ Share Value less the aggregate value of Time-Based Shares already used to satisfy prior indemnification claims, or the Third Year Cap. If and to the extent that any of the First Year Cap, the Second Year Cap or the Third Year Cap were met, then ISCO Indemnified Parties would not be entitled to any further indemnification.
 
 
Employment Agreement with Mr. Fuentes
 
In connection with the merger, we entered into an employment agreement with Mr. Fuentes. Pursuant to the employment agreement, Mr. Fuentes will report to our Chief Executive Officer, or the CEO, to assist the CEO in the coordination and integration of the surviving corporation’s operations with the combined entity and perform such other duties as the CEO may assign to Mr. Fuentes. During the term of the employment agreement, Mr. Fuentes’ base salary will be $240,000 per year. The term of the employment agreement is for two years; provided, however, that upon the eighteen-month anniversary of the start of his employment and each day thereafter the term may be extended for one additional day unless and until we provide written notice to Mr. Fuentes that such extension would not occur. If Mr. Fuentes’ employment were to cease due to a termination by us other than for Cause or by Mr. Fuentes for Good Reason (as those terms are defined in the employment agreement), then subject to Mr. Fuentes’ compliance with certain covenants, Mr. Fuentes would receive (i) monthly severance payments equal to 1/12th of his base salary for the lesser of: (x) three months or (y) the number of whole months remaining in the term as of the date of his termination and (ii) any accrued but unpaid base salary and any accrued but unused vacation as of the date of Mr. Fuentes’ termination. Mr. Fuentes intends to continue to serve on our Board of Directors at least for the remainder of his term, though he will not be considered independent under AMEX rules and no longer serve on any Board committees.
 
 
Registration Rights Agreement with James Fuentes and Non-Continuing Rightsholders
 
Also in connection with the merger, we entered into a registration rights agreement with Mr. Fuentes and certain Clarity rightsholders pursuant to which we agreed to register the shares they receive in connection with the merger for resale under the Securities Act on a registration statement on Form S-3, or other available form for resale by those individuals, to be filed by us within 30 days after the closing of the merger, subject to certain conditions.

PLAN OF DISTRIBUTION
We agreed to register for public resale, the shares of our common stock issued or issuable to the selling stockholders, or their pledgees, donees, transferees or other successors in interest in connection with (i) the lenders’ acquisition and conversion of the Notes and (ii) the issuance of shares of our common stock to Mr. Fuentes and the Non-Continuing Rightsholders in connection with the merger. The registration statement of which this prospectus is a part, has been filed with the Securities and Exchange Commission pursuant to certain registration rights agreements, the Loan Documents and the Merger Agreement, as applicable. We have agreed to keep each such registration statement effective until the earlier of (a) the date on which all the holders of the registered shares have completed the sales or distribution of such shares or, (b) until such shares may be sold by such holders under Rule 144(k) (provided that our transfer agent has accepted an instruction from us to such effect). The aggregate proceeds to the selling stockholders from the sale of shares offered pursuant to this prospectus will be the prices at which such securities are sold, less any commissions. The selling stockholders may choose to not sell any or all of the shares of our common stock offered pursuant to this prospectus.
 
The selling stockholders, or their pledgees, donees, transferees or other successors in interest, may, from time to time, sell all or a portion of the shares of our common stock at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such market prices or at negotiated prices. The selling stockholders may offer their shares of our common stock at various times in one or more of the following transactions:
 
·  
in the over-the-counter market;
 
·  
on any national securities exchange or market, if any, on which our common stock may be listed at the time of sale;
 
·  
through block trades in which the broker or dealer so engaged will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
 
·  
through purchases by a broker or dealer as principal and resale by such broker or dealer for its account pursuant to this prospectus;
 
·  
in ordinary brokerage transactions and transactions in which the broker solicits purchasers;
 
·  
through options, swaps, forwards, or derivatives;
 
·  
in privately negotiated transactions;
 
·  
in transactions to cover short sales;
 
·  
through any other legally permissible method; and
 
·  
through a combination of any such methods of sale.
 
The selling stockholders may also sell their shares of our common stock in accordance with Rule 144 under the Securities Act, rather than pursuant to this prospectus.
 
The selling stockholders may sell their shares of our common stock directly to purchasers or may use brokers, dealers, underwriters or agents to sell such shares. In effecting sales, brokers and dealers engaged by the selling stockholders may arrange for other brokers or dealers to participate. Brokers or dealers may receive commissions, discounts or concessions from a selling stockholder or, if any such broker-dealer acts as agent for the purchaser of such shares, from a purchaser in amounts to be negotiated. Such compensation may, but is not expected to, exceed that which is customary for the types of transactions involved. Broker-dealers may agree with a selling stockholder to sell a specified number of such shares at a stipulated price per share, and, to the extent such broker-dealer is unable to do so acting as agent for a selling stockholder, to purchase as principal any unsold shares at the price required to fulfill the broker-dealer commitment to the selling stockholders.
Broker-dealers who acquire shares as principal may thereafter resell such shares from time to time in transactions, which may involve block transactions and sales to and through other broker-dealers, including transactions of the nature described above, in the over-the-counter market or otherwise at prices and on terms then prevailing at the time of sale, at prices then related to the then-current market price or in negotiated transactions. In connection with such resales, broker-dealers may pay to, or receive from, the purchasers of such shares commissions as described above.
 
The selling stockholders and any broker-dealers or agents that participate with the selling stockholders in sales of their shares of our common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of such shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.
 
From time to time, the selling stockholders may engage in short sales, short sales against the box, puts and calls and other hedging transactions in our securities, and may sell and deliver their shares of our common stock in connection with such transactions or in settlement of securities loans. These transactions may be entered into with broker-dealers or other financial institutions. In addition, from time to time a selling stockholder may pledge our shares pursuant to the margin provisions of our customer agreements with our broker-dealer. Upon delivery of such shares or a default by a selling stockholder, the broker-dealer or financial institution may offer and sell such pledged shares from time to time.
 
We are required to pay all fees and expenses incident to the registration of the shares of our common stock. We have agreed to indemnify the selling stockholders and their officers and directors and each person controlling a selling stockholder, which we refer to as the indemnified parties, against certain losses, claims, damages and liabilities, including liabilities under the Securities Act or any state securities law , and will reimburse each of the indemnified parties for any legal and any other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability or action. We have advised the selling stockholders that during such time as they may be engaged in a distribution of the shares of our common stock, they are required to comply with the anti-manipulative provisions of Regulation M under the Securities Exchange Act.

The validity of the shares of our common stock offered by this prospectus will be passed upon for us by Pepper Hamilton LLP, Philadelphia, Pennsylvania.

ITEM 15.INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
Section 145 of the Delaware General Corporation Law (“Section 145”) permits 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, by reason of the fact that he is or was a director, officer or agent of the corporation or another enterprise if serving at the request of the corporation. Depending on the character of the proceeding, a corporation may indemnify against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding if the person indemnified acted in good faith and, in respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. In the case of an action by or in the right of the corporation, no indemnification may be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine that, despite the adjudication of liability, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper. Section 145 further provides that to the extent a director, officer, employee or agent of a corporation has been successful in the defense of any action, suit or proceeding referred to above, 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.
 
Article 9 of our Certificate of Incorporation provides that we shall indemnify our directors to the full extent permitted by the General Corporation Law of the State of Delaware and may indemnify our officers and employees to such extent, except that we shall not be obligated to indemnify any such person (1) with respect to proceedings, claims or actions initiated or brought voluntarily by any such person and not by way of defense, or (2) for any amounts paid in settlement of an action indemnified against by us without our prior written consent. We have entered into indemnity agreements with each of our directors and officers, including directors of our wholly owned subsidiaries. These agreements may require us, among other things, to indemnify such directors and officers against certain liabilities that may arise by reason of their status or service as directors or officers, as the case may be, to advance expenses to them as they are incurred, provided that they undertake to repay the amount advanced if we are ultimately determined by a court that they are not entitled to indemnification and to obtain directors’ and officers’ liability insurance if available on reasonable terms.
 
In addition, Article 8 of our Certificate of Incorporation provides that a director of ours shall not be personally liable to us or our stockholders for monetary damages for breach of his or her fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to us or our stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for willful or negligent conduct in paying dividends or repurchasing stock out of other than lawfully available funds or (4) for any transaction from which the director derives an improper personal benefit.

We have obtained a directors’ and officers’ liability insurance policy which entitles us to be reimbursed for certain indemnity payments we are required or permitted to make to our directors and officers.
 
The Company agrees to indemnify, to the fullest extent permitted by law, each of James Fuentes (“Fuentes”) and the persons who are Clarity rightsholders whose shares of the Company’s common stock have not been registered on a Form S-8 prior to the closing date of the merger with Clarity (collectively with Fuentes, “Sellers” and each, a “Seller”), and each of the Sellers’ officers and directors and each person who controls such Seller (within the meaning of the Securities Act or the Exchange Act) from and against all losses, claims, damages, liabilities and expenses (including, but not limited to, reasonable attorneys' fees) (collectively, “Losses”) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in the Resale Registration Statement entered into between the Company and the Sellers, any related preliminary prospectus, prospectus or free writing prospectus, or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or any violation by the Company of any federal or state securities laws, except that the Company shall not be liable for any indemnification to the extent such Losses are caused by or contained in any information furnished in writing to the Company by such Seller expressly for use therein or by such Seller's failure to deliver a copy of the prospectus or any amendments or supplements thereto after the Company has furnished such Seller with a sufficient number of copies of the same.
 
 The Company will indemnify and hold harmless each of Manchester Securities Corp. and Alexander Finance, L.P., (each a “Holder”, and collectively, the “Holders”) each of their officers, directors, agents and partners, and each person controlling of each of the foregoing, within the meaning of Section 15 of the Securities Act and the rules and regulations thereunder with respect to which registration, qualification or compliance has been effected pursuant to the registration rights agreement entered into by and between the Company and the Holders on June 26, 2007, and each underwriter, if any, and each person who controls, within the meaning of Section 15 of the Securities Act and the rules and regulations thereunder, any underwriter, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document (including any related registration statement, notification or the like) incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, or any violation by the Company of the Securities Act or any state securities law or in either case, any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each Holder, each of its officers, directors, agents and partners, and each person controlling each of the foregoing, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability or action, provided that the Company will not be liable in any such case to a Holder to the extent that any such claim, loss, damage, liability or expense arises out of or is based (i) on any untrue statement or omission based upon written information furnished to the Company by such Holder or the underwriter (if any) therefor and stated to be specifically for use therein or (ii) the failure of a Holder to deliver at or prior to the written confirmation of sale, the most recent prospectus, as amended or supplemented.  The indemnity requirements pursuant to this paragraph shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent will not be unreasonably withheld).

ITEM 17. UNDERTAKINGS
 
(a)            The undersigned registrant hereby undertakes:
(1)            To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increases or decreases 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 a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
provided, however, that paragraphs (a)(1)(i) through (a)(1)(iii), above, do not apply if the information required to be included in a post-effective amendment by those clauses is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the Registration Statement.
(2)            That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)            To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)            If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the Registration Statement or made in a document incorporated or deemed incorporated by reference into the Registration Statement or prospectus that is part of the Registration Statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the Registration Statement or prospectus that was part of the Registration Statement or made in any such document immediately prior to such date of first use.
For purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(b)            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 provisions described in Item 15 above, 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 our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by we are against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
